(1) Background: Psychological flexibility, the ability to adapt to changing demands while staying true to personal values, is linked to better health behaviors. However, its relationship with cardiovascular health behaviors, particularly in Filipino populations, remains underexplored. (2) Aim: This study aimed to examine the relationship between psychological flexibility and cardiovascular health behaviors among outpatients in Rizal, Philippines, focusing on BMI, smoking, physical activity, and dietary habits. (3) Methods: A cross-sectional, descriptive-correlational design was used with 100 outpatient participants from selected hospitals. Psychological flexibility was measured using the Acceptance and Action Questionnaire-II (AAQ-II), and cardiovascular health behaviors were assessed using a modified version of the American Heart Association’s Life Simple 7 tool. Descriptive statistics and Pearson’s correlation were applied. (4) Results: The findings showed that respondents had neutral levels of psychological flexibility. While most exhibited intermediate BMI and physical activity, dietary habits varied. A significant positive correlation was found between psychological flexibility and whole grain consumption. However, no significant associations were found with BMI, smoking, or physical activity. (5) Conclusions: Psychological flexibility appears to influence specific health behaviors, such as dietary choices, but does not strongly correlate with other cardiovascular health behaviors. Further research is needed to explore its broader role in cardiovascular disease prevention.

Background: Food security and dietary diversity are essential determinants of maternal health, particularly among pregnant women in refugee populations who face heightened vulnerabilities due to displacement and inadequate living conditions. This study examines the impact of food security on dietary diversity and nutritional intake among pregnant Rohingya women residing in the makeshift camps of Ukhiya, Cox’s Bazar. Methods: A descriptive cross-sectional study was conducted among 96 pregnant Rohingya women from June to September 2022. Data were collected using structured questionnaires assessing socio-demographic characteristics, food security, and dietary diversity. Food security was evaluated using the Household Food Insecurity Access Scale (HFIAS), while dietary diversity was assessed through a 24-hour dietary recall and a 7-day food frequency questionnaire. Data were analyzed using SPSS (Version 26) and Stata (Version 13), employing descriptive statistics and chi-square tests to examine associations. Results: Most participants (57.3%) were food secure, and 85.4% demonstrated high dietary diversity, consuming seven or more food groups. However, 21.9% of households experienced severe food insecurity, highlighting ongoing challenges in food access. The highest consumption was observed for starch, flesh foods, dark green leafy vegetables, and vitamin A-rich fruits and vegetables (99.0%), while dairy products (69.8%) and organ meat (34.4%) were consumed less frequently. Despite high dietary diversity, severe food insecurity persists, indicating gaps in food assistance programs. Conclusions: While food support programs appear to contribute to high dietary diversity among pregnant Rohingya women, severe food insecurity remains a significant concern. Strengthening food security interventions, improving access to diverse nutrient-rich foods, and integrating sustainable food assistance models are essential to addressing these challenges. Future research should explore long-term strategies to enhance food security and assess the impact of targeted nutritional interventions on maternal health outcomes in refugee settings.

Pembrolizumab-induced myelitis in stage 4 renal clear cell carcinoma: a case report

Abstract Pembrolizumab, an immune checkpoint inhibitor targeting the programmed cell death 1 (PD-1) protein, is widely used for renal cell carcinoma but rarely causes central nervous system adverse events such as myelitis. A 58-year-old woman with stage IV renal clear cell carcinoma developed radiating hip pain, paresthesia, hypoesthesia (T10 and below), constipation, urinary retention, and sudden [...] Read more.
Pembrolizumab, an immune checkpoint inhibitor targeting the programmed cell death 1 (PD-1) protein, is widely used for renal cell carcinoma but rarely causes central nervous system adverse events such as myelitis. A 58-year-old woman with stage IV renal clear cell carcinoma developed radiating hip pain, paresthesia, hypoesthesia (T10 and below), constipation, urinary retention, and sudden right-eye blurred vision one month after her sixth cycle of pembrolizumab and lenvatinib. Neurologic examination revealed asymmetrical inferior paraparesis, upper motor neuron signs, and right eye papilledema. MRI demonstrated patchy hyperintensity on C2-C6 and T2-T5, supportive of myelitis. Intravenous methylprednisolone was initiated, leading to pain relief and motor improvement. This is the first reported case of pembrolizumab-induced myelitis in Indonesia, emphasizing the importance of early recognition and corticosteroid therapy for optimal recovery.

Background: The COVID-19 pandemic posed significant psychological challenges to frontline healthcare workers (HCWs), including anxiety, stress, and emotional strain. Aim: This study investigates the psychological impact on HCWs during the pandemic and explores coping strategies employed to manage distress. Methods: An integrative review was conducted using 24 studies published between January and December 2020. These studies were analyzed to identify common psychological outcomes and coping mechanisms among HCWs. Results: Healthcare workers experienced significant psychological distress during the COVID-19 pandemic, including anxiety, stress, insomnia, and depression. Anxiety was the most commonly reported issue, particularly among women, younger healthcare workers, and frontline staff. Stress levels were heightened by high workloads, exposure to COVID-19 patients, and inadequate protective measures. Coping strategies and self-care behaviors, such as seeking social support and utilizing institutional resources, varied in effectiveness across populations. Conclusion: The findings highlight the urgent need for targeted mental health support and resilience programs for HCWs, ensuring they are better equipped to face future health crises.

Effect of Different Processing Methods on Total Phenolic and Total Flavonoid Content of Selected Indigenous Vegetables

Abstract Foods rich in phytochemicals are well recognized for their role in the prevention of chronic disease development, in addition to fulfilling the nutrient requirements. However, different processing methods employed during preparation may affect their levels and functionality as they are sensitive to different processing parameters such as temperature and light. This study aimed to evaluate the effects of three common processing methods; boiling, fermentation, and drying (sun and solar drying, with and without blanching), on total phenolic content and total flavonoid content in cassava (Manhot esculenta Crantz), black jack (Bidens pilosa) and bitter lettuce leaves (Launaea cornuta [...] Read more.

This study aimed to evaluate the effects of three common processing methods; boiling, fermentation, and drying (sun and solar drying, with and without blanching), on total phenolic content and total flavonoid content in cassava (Manhot esculenta Crantz), black jack (Bidens pilosa) and bitter lettuce leaves (Launaea cornuta) grown in Mkuranga District in the Eastern part of Tanzania. Total phenolic content and total flavonoid content were analyzed by using the spectrophotometric method with the use of Folin-Ciocalteu and Aluminum Chloride reagents, respectively. Total phenolic content ranged from 0.9±0.14 to 85.7 ± 0.56 mg Gallic Acid Equivalent (GAE)/100g and flavonoids ranged from 0.03±0.00 to 3.9±0.03 mg/100g across the treatments. Both parameters were adversely affected by fermentation and boiling, while solar and sun drying only reduced the flavonoid content. Results showed that direct solar and sun drying appear to be effective processing methods, for the retention and maintenance of total phenolic content in all samples while, none proved to be effective for flavonoid content.

We present a case of a critically ill patient with severe Legionella pneumonia complicated by morbid obesity (BMI ≥ 40 kg/m2) who was successfully treated with early initiation of veno-venous ECMO (V-V-ECMO) without any sequelae. The patient, a 48-year-old male, initially presented with symptoms of a sore throat, fever, significant fatigue, and decreased appetite. Upon diagnosis of severe pneumonia complicated by morbid obesity, he was transferred to our hospital for further management. Upon admission, he was promptly intubated and placed on mechanical ventilation. Due to a positive urinary Legionella antigen test indicating a risk of deterioration, V-V ECMO was initiated immediately after intubation. During ECMO support, the patient received Levofloxacin Hydrate at 500 mg/day and Prednisolone Sodium Succinate at 100 mg/day. He was successfully weaned off ECMO after 12 days and transferred back to the referring hospital on day 20. While ECMO therapy for morbidly obese patients was traditionally considered relatively contraindicated, this case suggest that obesity alone is not a contraindication to initiating ECMO.

Threatened Wildlife for an Instructional Approach about Biodiversity Conservation

Abstract Biodiversity is related to a global problem: its destruction, a fact supported by scientific authorities. It is not trivial that educational dimension has been contemplated as one of the strategies for its conservation. Since 1992 global initiatives such as the Convention on Biological Diversity postulates concepts that linked education and nature conservation. The main objective of this research work is to test the level of assimilation of extracurricular scientific knowledge by primary school pupils. The method chosen for the content was, on the one hand, a master class intervention with an interactive presentation on a digital whiteboard. Third cases were chosen. Each case consisted of a presentation of the current status of a species of fauna present in Spain. On the second part, students were asked to write an essay and to illustrate the experience during the presentation. Regarding the essays, students showed that they were more attracted to the first species that was presented (Iberian lynx) in a proportion of over 45% of cases. The “Endangered species” concept appeared in more than 77% of the texts reviewed. In terms of drawings, almost 55% of the responses seem to devote more attention to the second species described (Testudo graeca [...] Read more.

An attempt was made to offer rigorous, structured information related to different aspects of natural reality in order to contemplate the broadest possible vision. The example of an instructional intervention presented here aims to be an alternative to other transmissive teaching models. Likewise, the linking of abstract concepts with socio-cultural reality proved to be a successful strategy to reinforce knowledge about natural biodiversity, endangered species or threat factors.

The set of additional alien taxa here recorded for the vascular flora of Calabria includes: Acacia melanoxylon, Bidens subalternans, Buddleja davidii, Cucurbita moschata, Cyclospermum leptophyllum, Erigeron annuus subsp. annuus, Hesperocyparis glabra, Ligustrum ovalifolium, Mahonia aquifolium, Morus indica, Oenothera speciosa, Prunus serotina, Pyracantha fortuneana, Rudbeckia laciniata, Solanum nitidibaccatum, Sparaxis bulbifera, Tradescantia cerinthoides, Ulmus pumila. These additional 18 taxa bring the total number of alien species from 382 to 400. The most represented biological forms are scapose therophyte and scapose phanerophyte with 5 species (27.8% of the total). The most frequent biogeographic origins of the surveyed species are North America (6 species; 33.3%), followed by Asia and South America both with 4 species (22.2%). The most common habitats hosting the recorded alien taxa are roadsides (8 species; 44.4%), although all surveyed plants have been found in deeply anthropized environments. The altitude of occurrence, extending 3 to 1,286 m a.s.l., together with other ecological data provided, demonstrate the ability of aliens to potentially colonize a wide range of environments in the region.

Objective: aortic root enlargement (ARE) and descending thoracic aorta dilatation (DTAD) in combined aortic valve and ascending aorta replacement surgery (AV+AAR) are postoperative concerning issues. This retrospective observational analysis studies surgical factors which could determine those complications. Methods: 236 patients underwent AV+AAR. Mean-time follow-up by trans-thoracic echocardiography (TTE) and computer tomography (CT) was 44.7 ± 21.2 and 38.2 ± 18.4 months respectively. In long-term follow-up, outcome variables are: ARE equal/more than 10% of the preoperative TTE data and DTAD equal more than 5% of preoperative CT measurement at the same thoracic vertebrae axial slice. Results: ARE and DTAD appear strictly related to the discrepancy between prosthetic valve and straight vascular prosthesis diameters (p = 0.024), while there is not significant difference (log-rank = 0.917) related to aortic valve surgery type (replacement or repair). Considering diameter difference (DD) between vascular and aortic valve prosthesis, patients were subsequently grouped into two sections: L5 group, in which DD was less/equal than 5 mm, and M5, in which DD was more/equal than 5 mm. ARE was found in 30.8 % of L5 patients and only in 14.7 % among M5 patients (log-rank = 0.026). We have also observed descending thoracic aorta dilatation in 34.2 % of L5 and in 12.1 % of M5 (log-rank = 0.023). Conclusions: According with our data, difference between vascular prosthesis and aortic valve prosthesis equal/more than 5 mm is a protective factor against ARE and DATD.

Occupational lead (Pb) exposure continues to be an important public health problem globally, yet data is lacking on the associated risks and resources available for the prevention of Pb related diseases in low middle income countries (LMICs) like The Gambia. In this study, we used a case-control design to compare blood lead levels (BLLs) between the exposed (auto repair workers) and unexposed (healthcare workers) populations in The Greater Banjul Area. The data was analyzed using Chi square test of independence to determine the characteristic factors associated with BLL. Multivariate logistic regression was used to test the relationship between BLLs for auto repair and healthcare workers and their experiences. The results of this study indicated 82.1% of cases had higher BLLs compared to 52.9% of controls. Also, the proportion of workers with elevated BLLs was higher for certain factors including more than 80% of those with greater than 10 of years job experience, more than 70% of those who worked greater than 5 days a week, worked more than 8 hours per day, did not use personal protective equipment (PPE), were illiterate or had no formal education, and smoked or ate at work. The study results have implications for policies and practice in the auto repair industry and related workplaces in The Gambia and other LMICs with similar settings. Based on the findings of this study, it is essential to initiate discussions to establish national occupational health policies in The Gambia aimed at protecting workers and the general population.

In this study, we have investigated the status of faults in terms of precession and subsequence, and their relationship with vein mineralization in Kaybarkuh intrusive body in East of Iran. At least, three generations of faults are evidenced in Dasht-e-Bayaz (DB) fault terminal. During formation of faults, the stress orientation in the region has changed at least once probably due to DB fault evolution. Mineralization, especially gold and copper, is formed along the third-generation faults and sometimes on the fault surfaces. It can be predicted that mineralization also happened in the tensioned area of Kal-Shur covered by salt playa and Quaternary sediments, which requires subsurface and geophysics studies.

The government of Mexico City carried out the introduction of palm trees in the 50s to increase the visual appearance of the main avenues. As a result of introduction of these exotic species, phytosanitary problems appeared. Currently there is scarce information on how to evaluate the health of these majestic monocots, in this sense, it is necessary to implement assessment scales to determine the health condition of the most frequently found species to advance on their care and management. The present study had the following objectives: 1) To determine the current state of health of palm trees by means of a scale of visual evaluation of the crown; 2) To know the diversity and structural characteristics of palm trees and 3) To determine the influence of composite variables on the ecosystem services such as the amount of shade provided. Health of palm trees were evaluated two times (dry and rainy seasons in 2022) on 35 transects of 200 m length. An imaginary circle divided into twelfths was overlapped on palm tree “crowns”, and through it, two absolute variables, Live Crown Ratio (LCR) and Crown Quality (CQ) were evaluated. Composite variables were also calculated. The 12/12 health scale adapted in the present study was useful. Four health categories were obtained for the Live crown ratio (LCR): 7.62% of the palm trees were in critical condition, 7.80% were in intermediate condition, 80.36% were in normal condition, and 4.20% were in excellent condition. Meanwhile, for crown quality (CQ), the percentages were 13.50%, 20.00%, 56.96% and 0.43%, respectively. The total height and “crown” diameter showed a positive correlation with the volume composite variables. The shadow area projected as an important ecosystem service increased as the health of the palm trees improved. This is the first study on palm trees health assessment in Mexico City.

Studies on the use of pesticides in southwest Nigeria have revealed a substantial rise in a variety of pesticide-related illnesses, including mental impairment and reproductive problems. Those who work in agriculture and are regularly exposed to pesticides are the most impacted. The World Health Organization (WHO) predicts that three million severe pesticide poisoning episodes occur globally each year, with at least 300.000 deaths and 99% of cases occurring in low- and middle-income nations. The effects of longer-term exposure to pesticides on health are not yet precisely estimated. Objectives: To this end, the objective of this study is to assess the knowledge of pesticide residues and common pesticides in grain-based food (brown and white beans, yellow and white maize, brown millet and rice) about pesticide use in selected markets of Southwest Nigeria. Methods: A total of 240 respondents were selected from four states (Ado-Ekiti, Ibadan, Osun and Ondo) with the aid of structured questionnaire and interview guide using purposive sampling technique. The markets were Oja-titun (market) Ile-Ife, Osun; Alesinloye Market Ibadan, Oyo; Oja Oba, Ado-Ekiti, Ekiti; and Oja Oba, Akure Ondo State. The identification and quantification of pesticide residues was done using a Varian 3800/4000 gas chromatograph mass spectrometer while 60 structured questionnaires were administered to respondents including food merchants, buyers/consumers as well as food vendors. Data were analysed using descriptive statistics. Results: The experiment was conducted from November 2020 to November 2021. Up to 50.4% never read instructions on pesticide application while a shared 24.8% read them always and occasionally. The number of respondents who never read the instructions were particularly high in Ekiti and Ondo, up to 52.5% of the respondents in Ekiti do not know whether or not they are exposed to pesticides during application. Also, majority of the respondents never attended any professional training on pesticide application, this amounted to 79.3%. Most people were not aware that unsafe pesticide application is harmful to human health. Similarly, a wide variety of symptoms were reported by respondents following pesticide application or consumption of grains, these included headaches and dizziness, itching and redness of the eyes, skin allergy, diarrhea, and stomach disorder, vomiting and loss of appetite, weakness of the body, asthma, permanent skin patches, shortness of breath, excessive sweating. Millet recorded the highest number of OCP residues while maize had the lowest. On the contrary, maize had the highest number of OPP and carbamate residues while millet had the lowest number of OPP residues. Meanwhile, maize, rice and beans had only one carbamate pesticide residue. Conclusions: According to the study's conclusions, farmers who can only get information from agricultural extension officials should receive urgent and immediate attention for raising awareness. Additionally, extensive IPM training programs must be created with the intention of disseminating precautions for protecting human health and a healthy agro-ecosystem. In order to find more effective pest management methods that utilize less pesticides, it is crucial to reevaluate the pesticide residues and common pesticides found in grains in the targeted markets. To reduce farmers' exposure to pesticides, it is also required to establish personal protective measures, special educational initiatives, and legislation promoting the use of safer pesticides. Significance and novelty: This study gives policymakers a comprehensive understanding of the ways that may be utilized to close the significant knowledge gap on pesticide residues in grains and provides an insight into the knowledge of pesticide residues and common pesticides in grains.

Background: Shiga toxin producing Escherichia coli (STEC) inducing hemolytic uremic syndrome (HUS) with multiple organ involvement is associated with significant morbidity and mortality. The treatment has mostly been focused on kidney, respiratory and cardiovascular supports and not against the bacteria that cause STEC-HUS. The use of bactericidal therapy has been shown to be antibiotic dependent and certain antibiotics inhibit the production and release of Shiga toxin, eradicate STEC without harmful effects, and improve outcome. Methods: A previously healthy 18-months-old girl with STEC causing severe colitis, kidney failure and multi-organ dysfunction was treated with antibiotics that were known to inhibit the release of Shiga toxin as a supplement to supportive care. Results: The antibiotic regime stopped the pathophysiological process with prompt clinical improvement in association with the disappearance of the Shiga toxins. Conclusions: The present case report fortifies and recommends appropriate antibiotic treatment during STEC-HUS, suggesting clinicians to consider the use of these in severe STEC-HUS as early as possible.

Calabria is a floristic hotspot just at the center of Mediterranean Sea. Unfortunately, an increasing number of alien plant species threats this natural heritage, exactly while the crucial role of botany in secondary schools of Italy has been definitely dismantled. Calabrian Native Project is an environmental education project planned by Istituto Tecnico Agrario of Catanzaro that, reintroducing some key concepts of botany and biogeography, allowing pupils to experience a botanical excursion in the close-to-the-school Mediterranean Biodiversity Park, gives them the opportunity to become acquainted with both native and alien species. Pupils are asked to collect native plant propagules and to seed or cultivate the material in the school greenhouses, and to take care of these plants until their use. The prevalent outdoor and laboratory approach to the issue of bioinvasions, make the project very effective. This feature, with the low cost and reduced technology inputs, make the project highly replicable in other contexts, just focusing appropriate target species.

These equations are paradigmatic for modeling complexity and chaos. Even the simplest equation , easily leads to complex dynamics, its solutions are perfectly suited to simulate strong nonlinear phenomena such as large-to-small cascades of structures, intermixing, formation of fractals, etc. Second, in the main body of the article we present a small but very important part of the theory behind the above equation marked by . Just as the discrete-time analog of this equation induces the one-dimensional dynamical system on some interval , so the equation induces the infinite-dimensional dynamical system on the space of functions . In the latter case, not only are the long-term behaviours of solutions critically dependent on the limit behaviour of the sequence (as in the discrete case) but also on the internal structure of as . Assuming to be continuous, we consider the iterations of as the semigroup generated by on the space of continuous maps, and introduce the notion of a limit semigroup for in a wider map space in order to investigate asymptotic properties of . We construct a limit semigroup in the space of upper semicontinuous maps. This enables us to describe both of the aforementioned aspects of our interest around the iterations of.

Anthyllis hermanniae L. subsp. brutia Brullo & Giusso (Fabaceae): population survey and conservation tasks

Abstract Anthyllis hermanniae subsp. brutia, is an Italian endemic shrub occurring just in one locality by the Calabrian Ionian coast in southern Italy. Objective of this study is to provide data on population numbers, demography and ecology, as well as to identify the main threats on the long term conservation of the target taxon. The survey has been carried out through field census work, sampling biometric and dendrometric data, and applying simple statistics. The population, counting totally 962 individuals, is divided in two stands concentrated in the central part of the distribution area. It is restricted to a narrow belt on the inland part of the dune slope encompassed between an artificial pine forest at the dune top, and the dune-specialized vegetation on the slope. Some biometric insights, such as stem diameter, plant height and number of annual rings, suggest the role of micro-ecology in individual shaping. The most relevant threating factor for the long term conservation of this rare taxon is the rapidly spreading Pinus halepensis subsp. halepensis. Local population of this invasive alien species, deriving from planted individuals, is now invading the A. hermanniae subsp. brutia [...] Read more.

During the past few decades, many of the synthetic chemicals are able to produce nanoparticles and nanoclusters, although these chemicals primarily act as reducing and capping agents, they are very toxic and hazardous and make the nanoparticles biologically incompatible. Thus there is need for green chemistry that includes a clean, non-toxic and environmental friendly method of nanoparticles synthesis. Cobalt, iron and copper nanoparticles were synthesized using the stem-bark extract of khayasenegalensis (mahogany) where cobalt chloride (CoCl2 6H2O), ferric chloride (FeCl2), and copper sulphate (CuSO4 H2O) were used as the metal precursor respectively. The change in color from light brown to dark brown indicates the formation of cobalt nanoparticles, from light brown to dark green indicates the formation of copper nanoparticles and also the change in color from light brown to a dark color indicates formation of iron nanoparticles. The nanoparticles were further characterized using UV visible spectroscopy, FTIR, and SEM. The UV result for CoNPs showed the highest peak at 500nm and both FeNPs and CuNPs showed the highest peak at 300nm. The FTIR results for all the nanoparticles showed the presence of Alkaloids and triterpenes. Also the SEM result showed spherical granular, partially dispersed and monodispersed morphology for CoNPs, FeNPs and CuNPs respectively. Moreover, the antibacterial activity of the synthesized NPs when tested against two gram positive bacteria and two gram negative bacteria was evaluated and good results were obtained. The antifungal activity when tested against two fungi showed a very good result.

We present a case of untreated type II odontoid fracture, which evolved in severe dislocation 18 months later. Delayed dislocations in untreated type II odontoid fractures are already reported in literature. The singularity of our case is that CT-scan showed signs of fusion in the right C1-C2 articulation, which could have required a more complex surgical procedure to realign the upper cervical spine. Surprisingly, a CT scan performed in the extension position showed complete mobility of C1 and allowed us to perform a one stage posterior fixation. We want to highline both the importance of treating an Anderson type II fracture to prevent dislocation (acute or delayed), and the possibility to perform a flexion-extension CT scan to project a better surgical plan.

Objective: The effects of muscle fatigue appear to elicit a transient means of postural instability; however, the recovery of postural stability after fatiguing exercise has not been extensively studied. This study aimed to determine the immediate effect of local vibration applied to fatigued plantar flexor muscles on postural stability in healthy young adults. Design: True Experimental (pre-test - post test design with a control group). Setting: A tertiary care centre. Participations: 42 healthy young adults. Intervention: Fatigue of plantar flexors muscles was induced by repeated dynamic contractions performed to maximum exhaustion. Experimental group (n= 21) received local vibration to fatigued muscles with a handheld vibrator whereas the control group (n = 21) received no intervention (rest). Postural stability was assessed using one leg stance test (OLST) under three different conditions viz. pre-fatigue, post-fatigue and post rest/vibration. Results: Comparative analysis of postural stability within the group was done pre-fatigue, post-fatigue and post rest/vibration condition using Kruskal-Wallis test. A significant decrease from pre-fatigue to post-fatigue condition (p-value < 0.001); and a significant increase from post-fatigue to post rest/vibration condition (p-value < 0.001) was observed in OLST in both - control group and experimental group. However, further comparison of OLST between the groups (using unpaired t test) showed a significant difference in post-fatigue condition versus post rest/vibration condition in favour of the experimental group. Conclusion: Plantar flexors fatigue significantly affects one leg stance time in healthy young adults. Results of this study show that there is an immediate effect of vibration to fatigued muscles on recovery of postural stability in healthy young adults. Recovery of postural stability achieved quickly with such a simple tool may help increase the degree of participation in sports and other similar activities which can cause muscles to fatigue. However, more studies are required to determine this effect using other clinical measures.

Introduction: Colorectal cancer during pregnancy is a complex and rare condition often presenting with benign gastrointestinal symptoms that overlap with normal pregnancy related changes, leading to delayed or misdiagnosis. Further, hepatic metastases may complicate recognition, especially when initially interpreted as benign lesions such as hemangiomas. So, early identification and management are crucial and remain challenging for optimizing maternal and fetal outcomes. Clinical Description: A case of 39-year-old gravida 5 para 4 at 24 weeks+1 day with chronic hypothyroidism, longstanding anemia and a one year history of epigastric + right upper quadrant pain with suspected hemorrhage from a known liver hemangioma. Further imaging suggested a malignant hepatic lesion where colonoscopy and biopsy confirmed stage IV metastatic colon adenocarcinoma with liver and adrenal metastases. Her condition deteriorated and delivered a stillborn infant at 26 weeks of 780 grams following placental abruption. She continued to decline despite supportive care and died. Conclusion: This case illustrates the diagnostic challenges of colorectal cancer in pregnancy where nonspecific symptoms and inaccurate imaging results contributed to delayed diagnosis. The aggressive nature of the disease emphasizes the importance of prompt diagnosis and integrated care approach to improve both maternal and fetal outcome.

Background: Electronic cigarette (e-cigarette) use among adolescents is a growing public health concern, particularly in low-income and Black communities. However, little is known about how social determinants of health shape e-cigarette perceptions in this population. Aims: This study examined social determinants associated with perceptions of e-cigarette safety among Baltimore high school students. Methods: A cross-sectional survey (CEASE Youth: School Survey) was conducted with 604 Baltimore high school students aged 14–20. Participants completed a questionnaire assessing perceptions of e-cigarette safety, as well as parental education, race/ethnicity, parental employment, household composition, and community tobacco use. Results: Higher parental education was associated with lower perceived e-cigarette safety among students. Students in higher grades also reported lower perceived e-cigarette safety. In contrast, male students—particularly those in upper grades—were more likely to perceive e-cigarettes as safe. Race/ethnicity, household composition, parental employment, and community tobacco exposure were not associated with perceived e-cigarette safety. Conclusion: Higher parental education, female gender, and being in higher grades were associated with perceiving e-cigarettes as unsafe. These findings highlight the need for targeted interventions to address vaping perceptions among youth in urban settings.

Atypical Presentation of Lemierre’s Syndrome Masquerading as Gastroenteritis Lemierre’s Syndrome Mimicking Gastroenteritis

Abstract Lemierre’s syndrome (LS) is a rare clinical condition characterized by septic thrombophlebitis of the internal or external jugular vein, usually following an oropharyngeal infection. Here, we present a 20-year-old male patient who developed diarrhea, nausea, and vomiting after receiving clarithromycin for an upper respiratory tract infection. On admission, he had fever, hypotension, and elevation in acute phase reactants (WBC: 20,410/µL, CRP: 197 mg/L). Empirical treatment with ceftriaxone and metronidazole was initiated. Stool and throat cultures were negative. On the second day, abdominal tenderness developed; direct abdominal radiograph showed dilated bowel loops, but toxic megacolon was excluded during follow-up. Thoracic CT revealed septic emboli in the lungs. Due to persistent fever despite ceftriaxone and metronidazole therapy, treatment was escalated to meropenem on the fifth day. On the same day, blood cultures grew Fusobacterium necrophorum, raising suspicion of LS. Doppler ultrasound detected a thrombus in the left external jugular vein. Anticoagulant therapy with low-molecular-weight heparin and clopidogrel was initiated. The fever resolved by the seventh day of full antibiotherapy After three weeks of intravenous therapy, follow-up imaging showed regression of the thrombus. The patient completed a four-week course of antibiotics and anticoagulants and was discharged with full recovery. This case highlights the diagnostic challenge of LS presenting with gastrointestinal symptoms and emphasizes the importance of early blood cultures and imaging.

The Free Senior High School (FSHS) policy implementation in Ghana has garnered significant attention in academic research, with various studies delving into its advantages and implementation obstacles. Nevertheless, there has been a rise in school dropout rates among secondary school students amidst the programme implementation. There is therefore the need for a more localized scientific inquiry into the socio-economic factors contributing to school dropout among Senior High School (SHS) students in the Abofour community. The study employed a qualitative approach, using the case study design to conduct interviews with 22 students who had dropped out of SHS, to explore their experiences and identify key socio-economic factors influencing their decisions to leave school. Thematic data analysis revealed six main themes, namely, lack of parental support, peer influence, early marriage and pregnancy, economic conditions, and unsupportive school environment, as among the causative factors. The findings suggest that while the Free SHS policy has removed some direct financial barriers, other social, economic, and institutional factors continue to spur up dropout rates. The study concludes that addressing these underlying issues requires a multi-faceted approach that includes strengthening family support systems, improving school environments, and providing targeted interventions for at-risk students. In this regard, policymakers and other educational stakeholders are required to provide targeted supports to enhance student retention and reduce dropout rates in the Abofour community.

Marcus Gunn syndrome or unilateral trigemino-oculomotor syncinesis is a very rare autosomal dominant genetic disorder characterised by a combination of congenital ptosis and mandibulopalpebral syncinesis during certain mandibular movements. We report a series of two cases of children with Marcus Gunn syndrome. Case 1: A 5-year-old boy with no previous pathological findings presented with unilateral ptosis of the left upper eyelid at the age of 4 months. His visual acuity was 10/10 in right eye on the right and 5/10 in left eye. Second case: a 7-year-old girl, brought in by her parents for a ptosis of the left eye noted at birth. This is a 7-year-old girl brought in by her parents for ptosis of the left eye, diagnosed at birth. She had no particular pathological antecedents. Her visual acuity was 10/10 in right occlusion and 3/10 in left occlusion. Both children had undergone sectioning of the superior levator muscle with frontal suspension using prolene sutures, with good progression, followed by total optical correction and treatment of the amblyopia.

Background: Propranolol is a non-cardio-selective beta-blocker, commonly used in patients with hyperthyroidism to treat the hyperadrenergic symptoms but also for its additional effect of blocking the peripheral conversion of inactive T4 to active T3. However, propranolol has many side effects, one of them being secondary Raynaud phenomenon. Case presentation: S.K., 55 years old was hospitalized in the Endocrinology Department as an untreated hyperfunctioning goiter with typical clinical manifestations such as fatigue, anxiety, palpitations, heat intolerance, difficulties in swallowing and breathing. Unimazole 5 mg (2-2-2 tb) and Propranolol 40 mg (¼ -0- ¼ tb) were prescribed. Thirty minutes after taking Propranolol (the dose 40 mg), she had difficulties breathing, was agitated, sweating and had nausea. Her face was hyperemic and edematous and her extremities were getting blue and cold. Her vitals remained stable and her airways were opened, as evaluated from laryngoscopy and CT-scan of the neck. 8 hours later, her clinical manifestations got worse: her facial edema spread in her lips and submandibular region. On both cases, she clinically improved after prednisolone administration. 12 hours after taking propranolol, she showed no more signs of cyanosis or edema. Propranolol was replaced by Nebivolol, with no side effects. Conclusion: Secondary Raynaud phenomenon is a common side effect of beta-blockers and should be taken in consideration in very patient presenting with cold and cyanotic peripherals. In these cases, propranolol should be stopped and replaced. Further studies on beta-blockers side effects in patients with hyperthyroidism should be made.

Objective: This study explores the relationship between neighborhood stress and Body Mass Index (BMI) in adolescents, while also examining whether this association differs between Black and White adolescents. Methods: Data from the Adolescent Brain Cognitive Development (ABCD) Study were analyzed using linear regression models to examine the association between neighborhood stress (defined as a composite score based on three items measuring perceived safety and neighborhood fear) and BMI in adolescents, controlling for demographic and socioeconomic variables. We tested models both with and without interaction terms to assess whether race moderated the association. Stratified analyses were conducted to further explore potential differences between Black and White adolescents. Results: A positive association was observed between neighborhood stress and BMI across the overall sample. However, this association was weaker for Black adolescents compared to White adolescents, even after adjusting for potential confounders. Conclusions: The contribution of neighborhood stress to higher BMI in adolescents may vary by race. Our findings suggest that while neighborhood stress is associated with increased BMI, Black adolescents appear to be less affected by these stressors than their White peers. This weaker association could be due to the normalization of stress in environments where it is pervasive (what is common becomes normal) or the presence of other significant risk factors affecting BMI in Black youth, such as poverty, limited food access, food culture, and food deserts. Future research should explore processes of habituation, inoculation, or even sensitization to stress among Black populations, who are often exposed to a wide range of stressors throughout the life course.

This study explores the integration of Adinkra symbols into the set design of Ghana’s Most Beautiful (GMB), a popular beauty pageant and reality TV show that has aired on TV3; a private television station in Ghana. GMB showcases beauty, intelligence, cultural knowledge, and traditional values, celebrating Ghana's rich cultural heritage through female contestants representing the country's diverse ethnic groups. In response to the lack of coherent Ghanaian artistic elements in previous set designs, this study employed an artistic methodology to incorporate four Adinkra symbols, Okɔdeɛ Mmɔwerɛ, Duafe, Dweninimmɛn, and Mate Masie, into the set design for the show’s eighth season. These symbols, signifying beauty, strength, wisdom, and unity respectively, were creatively integrated into a crown-like set design for the grand finale, harmonizing aesthetic trends with cultural significance. The design process was informed by rigorous research and stakeholder interviews, ensuring that the selected symbols conveyed the intended cultural messages. The results highlight the potential of traditional symbols to enhance both the cultural relevance and visual appeal of television productions. The project enriches the cultural depth of GMB production and offers a blueprint for incorporating indigenous symbols into contemporary set design. The study recommends that future productions continue exploring traditional symbols to deepen the appreciation of Ghanaian heritage and strengthen cultural identity through visual arts.

This aimed to examine the societal perception of new religious movements' televangelism in Dunkwa-On-Offin, Ghana's Central Region. The study used a sequential explanatory mixed-methods design, using the mixed methods approach to research. The population of this study comprised Women, Regular churchgoers, believers, and those listening to televangelism services by new religious movements, as well as clergy, lay leaders, and other male worshippers. Random and purposive sampling techniques were used to select 200 women and 20 men from House of Power Ministry International and GILGAL Pentecostal Prayer Ministry International as the respondents for the study. The instruments used for data collection were questionnaires and interview guides. IBM SPSS statistics software version 23 was used to analyse the quantitative data, while qualitative data was analysed thematically with an interpretative lens. The study has revealed that society perceives the televangelism movements as helpful and encouraging but could also create trouble in fundamental Christian worship principles. The study also indicates that televangelists emphasise material things rather than spiritual matters. Other concerns included that televangelism brings about the separation of family and friends because they always inform members that their friends and family are evil. It is recommended that there is the need to change or improve the credibility perception among Christians in Ghana about televangelism. Televangelists must exhibit accountability and integrity to their worshippers by providing adequate information to encourage viewers to support their ministries.

Background: Education is widely recognized as a key driver of wealth generation, providing individuals with the opportunity to enhance their socioeconomic status. However, the effectiveness of education in generating wealth varies significantly across different social groups. In the United States, research has shown that Black individuals experience weaker economic returns on education compared to their White counterparts, a phenomenon explained by the theory of Minorities' Diminished Returns (MDRs). Although MDRs have been documented in various countries, their relevance to caste-based disparities in India remains unexplored. Objective: This study aims to investigate the caste-based diminished returns of education on wealth in India. We hypothesize that the returns on educational attainment, in terms of wealth generation, will be weaker for individuals from Scheduled Castes (SCs) compared to those from higher castes, using data from the India Demographic and Health Surveys (DHS). Methods: This study was a cross-sectional analysis of DHS -2019/2021 data from India, examining the relationship between educational attainment and wealth across different caste groups (scheduled castes and non-scheduled castes). Multivariate regression models will be employed to assess the interaction between caste and education in predicting wealth outcomes, controlling for relevant covariates such as age, gender, and region. Results: The study is expected to find that the returns on education, in terms of wealth, are significantly weaker for individuals from Scheduled Castes compared to those from higher castes. This would indicate that caste-based discrimination continues to hinder the economic progress of Scheduled Castes, even when they achieve similar levels of education as their upper-caste counterparts. Conclusion: The findings of this study will extend the MDR framework to the Indian context, demonstrating that caste-based disparities result in diminished returns on education for wealth generation. This study underscores the need for targeted policies that address the specific barriers faced by Scheduled Castes in translating educational attainment into economic success and highlights the ongoing impact of caste-based discrimination in India.

The purpose of present study was to investigate the therapeutic outcome of clinical application of CSC telescopic denture with magnetic attachment in treating the occlusion, mastication and speaking problems due to individual affected severe teeth missing. Similar to above conditions, there are many dental clinicians may choose to use the removable denture with bilateral I-bar application. The other way also can use the bilateral implant application. Little or limited literatures reported the use of removable denture combined with magnetic attachment application. The present case presented one modified approach related to oral rehabilization of mandibular posterior teeth using bilateral magnetic attachments combined with CSC telescopic denture (CSCTD) application. Result showed a remarkable clinical appearance and occlusal function of the improvement between outer crowns with magnet attachment and inner abutment with magnet attachments for a long time evaluation. It can be concluded that the design of the CSCTD combined with magnetic attachment appears to be an effectiveness method and provided the other modified approach in treating bilateral missing problems of posterior premolar and molar teeth.

Background: Recent research has identified structural racism—systemic policies and practices that perpetuate racial inequalities—as a significant social determinant of population health. Studies utilizing data from the Adolescent Brain Cognitive Development (ABCD) study have shown an association between higher levels of state-level structural racism and increased tobacco use among youth in the United States. However, there has been limited exploration of the psychosocial mediators of this relationship, particularly in the context of youth aged 10-16 years. Objective: This study aimed to assess the roles of socioeconomic status (SES), tobacco susceptibility, and perceived discrimination as potential mediators in the relationship between state-level structural racism and youth tobacco initiation rates. Methods: We analyzed data from the ABCD study, a nationally representative longitudinal survey of 11,698 youth followed from ages 9/10 to 15/16. These data were combined with state-level indicators of structural racism. We employed structural equation modeling (SEM) to investigate the mediators of the association between structural racism and self-reported initiation of tobacco use, while controlling for individual and state-level covariates. Results: Our findings indicate that higher levels of structural racism were associated with increased rates of tobacco initiation among youth. This relationship was partially mediated by lower SES, but not by perceived discrimination or tobacco susceptibility. Conclusion: The association between structural racism and youth tobacco initiation appears to be influenced in part by the lower SES prevalent in states with higher levels of racism. These results highlight the need for addressing both racism and SES inequalities as key strategies for reducing tobacco disparities among youth.

Groundwater is undeniably crucial to people's lives, particularly in coastal regions. Therefore, it is imperative to address this vital water source strategically and implement a management plan to maintain its optimal state. The salinization of groundwater poses a significant challenge for coastal communities, stemming from factors like excessive groundwater extraction from coastal aquifers, reduced recharge, rising sea levels, climate change, and other causes. Saltwater intrusion (SWI) is a prevalent issue that needs attention, as it significantly threatens groundwater quantity and quality. SWI happens when saline water infiltrates coastal aquifers, contaminating freshwater supplies. This review article aims to define SWI, explore its causes and influencing factors, and discuss various monitoring techniques. Additionally, it examines different modeling methods and management tools, including remote sensing, field surveys, modeling approaches, and optimization techniques. To mitigate the adverse effects of SWI, several control measures are outlined, along with their pros and cons. The final section reviews previous SWI studies and case studies from the Nile Delta, Sinai Peninsula, and North-West coast in Egypt. These studies offer suggestions, adaptations, and mitigation measures for future research.

Clinical differences between hospitalized patients with COVID-19-related pneumonia and those with influenza-related pneumonia during the omicron variant surge

Abstract Background: COVID-19-related pneumonia was initially rare, though influenza-related pneumonia is well known as a severe complication of influenza. However, COVID-19-related pneumonia may be increasing since the omicron variant of COVID-19 appeared. Methods: The clinical differences between COVID-19-related and influenza-related pneumonia patients were retrospectively investigated in patients hospitalized from January 2022 to December 2023. Results: COVID-19-related and influenza-related pneumonias were found in 46 of 285 (15.8%) and 6 of 12 (50.0%) patients, respectively (p<0.001). Their mean ages were 75.5 (45-93) years and 53.8 (19-73) years in COVID-19-related and influenza-related pneumonia cases, respectively (p=0.002). Aspiration pneumonia was more common in COVID-19-related pneumonia (28/46=60.9%) than in influenza-related pneumonia patients, and it was treated by sulbactam/ampicillin (31/46=67.4%). The influenza-related pneumonia patients were more often infected in the work place (2/6=33.3%) and not vaccinated (4/6=66.7%), compared with COVID-19-related patients. Death occurred in 7 of 46 (15.2%) COVID-19 patients, but none of 6 influenza-infected patients died. Conclusions: [...] Read more.

Qualitatively, the study focused constructivist research paradigm. A case study research design was adopted for the study. The study population comprised all six (6) Social Studies teachers, the headmaster and the School Improvement Support Officer (SISO). Purposive and convenient sampling techniques were used to select the participants for the study. The main instrument for data collection was a semi-structured interview guide and observation protocol. The data were analysed using the interpretative technique based on the themes arrived at during the data collection from the semi-structured interview. The study revealed that multimedia usage is a quality enhancer in educational settings for teaching Social Studies concepts. It also indicated that teachers perceived their incompetence when using technology as they feel less in control of their classes and are unlikely to explore new possibilities that utilise technology when planning their lessons. They learn the theoretical aspect and practice and perceive the teacher’s role in the classroom changes from an instructor to a facilitator, which changes the teaching method to student-centred (constructive methodology) which aids content absorption by the learner through learning by doing. The study also indicated that teachers perceived their incompetence when using technology as they felt less in control of their classes and were unlikely to explore new possibilities that utilised technology when planning their lessons. It is recommended that the Ministry of Education and National Teaching Council collaborate with Ghana Education Service to set up Social Studies training centres in all the district capitals equipped with competent staff to periodically organise in-service training for teachers to build their capacity on how to pedagogically incorporate multimedia resources in their instructions to improve students learning outcomes.

Challenges are part and parcel of human activities. Quantitatively, a relational survey model research was adopted for the study. The population for this study comprised all Junior High School (JHS) Religious and Moral Education (RME) students in Bokro M/A JHS and the Eziom Methodist JHS in the Nzema-East Municipality of the Western Region. Purposive and random sampling techniques were used to select the schools and respondents for the study. The main instruments for data collection were a test and a questionnaire. The data from both the control and experimental groups on the challenges learners face in using the flipped classroom model in RME were analysed using means and standard deviations. The study indicates the challenges learners face by employing the flipped classroom model to learn include lack of data to access the internet, frequent light outs, lack of technological devices to access contents, frequent power outages, and difficulty in comprehending some of the materials given to them. Given that learners face frequent power outages during periods that they watch videos assigned to them by their teachers, it is recommended that the government and the Electricity Company of Ghana ensure that there is a constant flow of power to allow learners trying to use the flipped classroom to learn are without any hindrance. It is also recommended that the Ghana education service should organise continuing professional development for RME teachers on effective uses of technology in teaching and learning subject concepts. The government should also supply the basic schools with all the needed technological devices to promote effective teaching, learning and assessment.

Qualitatively, the study adopted a content analysis approach. There were eight State of the Nation addresses that the Ex-President John Kufour delivered during his tenure of office but only two of them are analysed in this study. The purposive sampling approach was used to select two State of the Nation addresses samples. The State of the Nation addresses of two years were picked for the study. The years are: 16th February 2001, and 14th February 2008. The qualitative data was analysed by the use of the interpretative technique based on the themes arrived at during the content analysis of the two speeches delivered by ex-president Kufour. Selective coding was used to code the occurrence of the categories of the epistemic modality expressions in the data. The epistemic modal elements as well as the sentences in which they occurred were then manually copied for further verification. These processes made the frequency count faster, more effective and more accurate. The data shows the relevant clauses or sentences containing modal expressions sampled within the contexts of epistemic meanings in the texts. The study has made it apparent that the expression of certainty is predominant. The data also indicates that the Ex-president has a greater tendency to use more modal adjuncts followed by the other modal auxiliary verb categories in expressing certainty in the selected State of the Nation Addresses during his State of the Nation Addresses. One question that arises is, why the Ex-president had a greater tendency to express more certainty in his State of the Nation Addresses. The answer is that Ex-president was fully sure and convinced of the information on the nation’s development and future programmes captured in the addresses. Thus, he appeared a confident, trustworthy and knowledgeable leader. Furthermore, the use of epistemic modality in the State of the Nation Addresses is neither haphazard nor coincidental. Instead, it is informed by reason of specific communicative intent. It is recommended that Public speakers and politicians should take the epistemic markers into consideration when writing the State of the Nation Address or any other texts in order to clarify shared opinion. It is also recommended that the Faculty of Language of the University of Education of Winneba should consider the concept of epistemic modality as a course of study in all various Language Departments including the Department of Communication Skills.

The purpose of this study was to use an activity-based method to enhance the teaching and learning of Redox reactions among senior high school learners at Christ the King at Obuasi in the Ashanti Region, Ghana. Quantitatively, the study employed an action research design. The population of the study comprised all final-year elective chemistry students of Christ the King Senior High School (CKC) in the Ashanti region of Ghana. A purposive sampling technique was used to select thirty-five (35). The instruments used in the study were tested. Percentages of students who responded correctly to the pre-test items were compared to percentages of students who responded correctly to the post-test items. The pre-test and post-test mean scores were compared to see if there was any difference in their mean scores. The use of an activity-based teaching method in teaching chemistry appears to be used effectively in imparting the content knowledge of chemistry to students to become successful in their learning. Regarding the benefits of the activity-based method. The use of activity-based teaching methods in redox reaction motivates students to be self-learners and improves performance. It is also evident from the findings of this study that the use of the activity-based method of teaching could enhance student performance in a redox reaction. It is recommended that activity-based methods of teaching should be encouraged to be used by chemistry teachers in the Senior High Schools of Ghana in teaching redox reaction concepts to enhance students’ performance in redox reactions. It is also recommended that the Ghana education service should collaborate with the chemistry teachers’ Association of Ghana to organize professional development programs, seminars, and workshops for chemistry teachers on activity-based to improve their knowledge of teaching skills.

This study was conducted with beans to determine a protocol that will help reduce the cooking time of beans. It was carried out in the Foods laboratory at the University for Development Studies, Department of Family and Consumer Sciences. A quasi-experimental design was the design tool employed for this study to establish a cause-and-effect relationship between an independent and dependent variable where the independent variable is cooking time and dependent variable is softness of the beans. An experiment was carried out to text the effect of 2 different treatments given to beans during cooking to ascertain which treatment is best for reducing the cooking time for bean. The treatments meted out were addition of blended onion, crushed cassava and no additives. Addition of blended onion had a very significant effect in reducing cooking time with cooking time of 43minutes. Cooking beans with crushed cassava also saw some reduction in the cooking time for beans with 46 minutes. Cooking dry beans with no additive having the highest cooking time (47minutes). With quantity of water, the dry beans sample with crushed cassava used more quantity of water (3.4 liters). Cooking with blended onion and with no treatment both used 2.9 litres per 100grams beans each. The study therefore recommends that crushed onions are added to help reduce the cooking time of dry beans.

The purpose of this study was to examine Religious and Moral Eduction teachers’ usage of the flipped classroom model Model and its Influence on JHS Students’ Academic Performance in the Nzema-East Municipality of Ghana.The study adopted the quasi-experimental research design. The population for this study comprised all JHS Religious and Moral Education students and teachers within the Nzema-East Municipality of the Western Region. With the help of the Krejcie and Morgan’s sample determination table, a sample of 110 comprising 10 teachers and 100 students were selected for the study through multi-stage sampling. The instruments used for data collection were tests and questionnaires. The study indicated that, the flipped classroom is a very potent method of teaching RME. This is so because the study provides enough evidence that the flipped classroom significantly improves the performance of learners more than the traditional approaches to teaching. This is even more appropriate in a technological era such as ours. The study also revealed that, teachers have a positive view of the use of the flipped classroom in teaching RME. Junior High School RME teachers are ready to adopt the flipped classroom model in their teaching provided challenges students face are eliminated. It is recommended that, School Improvement Support Officers and Headteachers should ensure that teachers use the flipped classroom to bring variations in lesson delivery so as to improve the academic achievements of learners. It is also recommended that government should provide technological devices to schools and teachers and ensure that teachers employ the various technological devices at their disposal to the benefit of their students.

Exercise is an important factor of rehabilitation in heart failure patients, improving several indicators of disease prognosis and functional capacity. The aim of the present study was to examine the effect of a cardiorespiratory rehabilitation program on the physical and mental fatigue, general health and anxiety in patients suffering from heart failure. Thirty-one patients with heart failure [(M±SD) age: 67.59±7.60 years] participated in a cardiorespiratory rehabilitation program. The program included aerobic exercise on cycle ergometers and muscle strengthening for 3 months (12 weeks), 3 times/week. Before and after the program, patients' fatigue, general and mental health were assessed using the following self-reported questionnaires: a) Fatigue Assessment Scale (FAS), b) Goldberg's General Health Questionnaire (GHQ-28) and c) Spielberger's Anxiety Questionnaire. Data analysis showed a statistically significant tendency of reduction in social dysfunction (from 1.99±0.42 to 1.75±0.45, p=0.05), while anxiety (from 27.10±7.61 to 26.40±4.35) showed no change (p>0.05).Also, evaluating the changes in the health level after attending the program, there was a trend of improvement in physical activity and functioning with the appearance of fewer physical symptoms (from 1.38±0.43 to 1.24±0.31, p=0,13). These results show that exercise can contribute to increasing the general well-being of these patients and reducing feelings of helplessness, making them able to cope with their daily activities and tasks.

The study used a randomized complete block (RCBD) experiment in which 8 treatments in 4 replicas of each to make a total of 32 sub-plots. Two rows of maize spaced at 4.5cm within rows and 90cm between rows were intercropped with two rows of velvet beans spaced at 30cm with rows and 90cm between rows. Two rows of NABE16 spaced at 4.5cm within rows and 75cm between rows were intercropped with maize a pacing of 5.5cm within rows and 75cm between rows. Rows of beans were separated from those of maize by 75cm in a 10m by 8m sub-plot. The experiment was conducted in two seasons (March to May 2020 and August to November 2021). Standard agronomical practices were followed from planting to harvesting, after which dry maize grain weight was taken and recorded. Data analysis was done using ONE WAY ANOVA in STATA version 13. Results show that the significant statistical difference in season one (p = 0.0000)** was higher than that in season two (p = 0.0211)*. The study concluded that unpredictable (too much or too little) rainfall negatively affects maize productivity. Early planting and application of organic fertilizers were recommended to improve maize productivity.

One of the current issues facing humanity is ensuring sustained global food security in the face of devastating effects of climate change; this challenge is particularly pressing on the African continent. Here, I present an opinion piece identifying local animal genetic resources as "African leverage point" that provide the highest chances to cushion rural fork to climate change, enhance environmental sustainability and food security in Africa. When it comes to boosting food production, coping with climate change, or bolstering the delivery of a wide range of ecosystem services, I believe that African animal genetic resources are essential alternatives for the sustainable growth of the livestock industry and its contribution to food security. Africa needs to address the support and development of indigenous animal genetic resources in order to meet the basic food needs of more than 1 billion people, address numerous environmental issues with continental implications, and focus on more effective and resilient food systems with the greatest impact on food security. The indigenous animal resources diversity and support actions to this unique group could provide a boost in protein that is lacking to constitute healthy diets in Africa. The priorities of nonprofit organizations, foundations, governments, citizens' groups, and companies can be influenced by this leverage point in the African food system. Due to continuous food insecurity, which appears to be becoming worse with climate change and makes it even harder to accomplish the SDGs on the continent, Africa has paid a hefty price for being misled about the worth of its own animal genetic resources. To the contrary, it is highly improbable that a strategy to improve food security and rural livelihoods that undermines the utilization of indigenous animal genetic resources will be viable in long-term. If Africa makes an effort, is committed, and fully commits resources to putting indigenous animal genetic resources at the forefront of combating food insecurity and accelerating the achievement of SDGs, it can achieve more under the adverse prevailing climate change induce environmental conditions. Our personal opinion is that we would not have had the ongoing food problems, even in the face of climate change, if Africa had over the years implemented the necessary mechanisms to develop and promote local animal genetic resources. What lies ahead in terms of climate change effect on food security in Africa is anyone's guess – but whatever it is, promoting continental adapted indigenous animal genetic resources portfolio is ready to handle it. Development and promotion of African animal genetic resources should be part of a continental strategy to transform smallholder animal production by 2050, in line with the goals of achieving the SGDs, to improve rural household food security, and bringing rural economy prosperity, resilience, sustainability, and all other desired animal related food outcomes for rural healthy diets. African animal genetic resources are the most important but underutilized resource to address the issue of ongoing food insecurity. The responsible use of local animal genetic resources through climate smart animal husbandry practices also contributes to food security, rural development and increased employment opportunities. African genetic improvement programs involving indigenous animal genetic resources must be considered as regards to local agriculture and livestock development aspirations, appropriateness to local reality and livelihood security, as well as environmental friendliness. Animal agriculture will fill in the enormous gaps in the continent's food supply if this animal group receives adequate attention and is used integrated properly in crop and livestock systems which characterize smallholder farming sector in Africa. Because they have evolved over time to accommodate the various climatic conditions and environmental pressures on the continent, Africa's native animal genetic resources are particularly resilient. Indirectly, the impact of climate change offers a chance to use native animal genetics from Africa. The use of local animal genetic diversity has the potential to substantially improve Africa's food security landscape hence should be given special consideration for sociocultural, environmental, and economic aspects, and with regard for smallholder farmer-specific factors of interest. African animal genetic resources have contributed significantly to the food and nutrition security aspects of the millions of people in their communities of origin and custody in Africa. The purpose of the perception piece is to educate the reader about the fundamental mechanisms that control the use of continental animal genetic resources and how the outlook for these mechanisms can be manipulated in the future for the benefit of improving food security in Africa. The discussion provides in-depth insight into the pertinent literature in understanding the significance of local animal genetic resources in terms of their contribution to food security in Africa.

The Adventures of Sasa and Esi is a dance theatre that takes its story reference from two short Ghanaian folktale stories the Adventures of Sasa and Esi, and the Witch of the Forest which were written by Martin Otchere Owusu and directed by Johnson Kwaku Edu and Latipher Amma Osei. The production was staged at the Amu Theatre of the Department of Theatre Arts, University of Education (UEW), Winneba from the 3rd to the 6th of November, 2016. Though the play was written for children it appeals to adults due to the lessons embedded in it. Both plays were adapted by the authors to include Ghanaian folk and popular contemporary choreographed dances and theatrical special effects make-up as key theatrical elements to drive the production and to project the element of spectacle. The style of presentation was naturalism and realism. The production also served as a learning platform for the cast and crew who were students in the Department of Theatre Arts, UEW as they participated in it. Through experimentation, experiences, and concept development, the directors’ style and professional background in technical theatre and creative dance heightened the element of naturalism and realism to underscore the theme of the play, understanding, and interpretation of the play.

In this review proteins associated with tight junctions (TJs) is described with an emphasis on prostate cancer. Overall tight junctional proteins do not seem to play a decisive role in prostate carcinoma pathogenesis. Of TJ proteins, expression of some claudins show an association with clinical behaviour of the tumors. Claudin 1 expression appears to be related to a better prognosis partly due to its involvement in EMT abrogation. Claudin 3 and 4 are highly expressed in prostate cancer and their expression is associated with aggressive behaviour. Inhibition of claudin 8 promotes prostate carcinoma invasion and spread but studies are few. CPE has been known to bind to especially claudins 3 and 4 and cause cell lysis. Several experiments with modified CPE have been made in prostate cancer cell lines. Regardless of this effective CPE based human treatment for prostate cancer have not yet been developed.

The importance of resistance training (Conley & Pennington, 2022; Pennington, 2020) cardiovascular fitness (Pennington, 2015; 2016), and anaerobic power (Pennington, 2014) cannot be overstated for individuals enlisted in our country’s armed forces. The Army Combat Fitness Test (ACFT) is the new branch wide fitness test designed to replace the outdated Army Physical Fitness Test (APFT) (USAPHC TG 358, n.d.). The APFT was implemented in 1980 as the measure of Service Member (SM) fitness. However, this test is very limited in scope and failed to tell unit commanders how ready their SMs were for the rigors of a combat environment (US Army ACFT Field Testing Manual, n.d.). The APFT was a gender-based test that consisted of three events: a two-minute pushup evaluation to measure upper body endurance. The second event was a two-minute sit up evaluation to measure core and hip flexor endurance. While the final evaluation was a two-mile timed run, which was designed to test aerobic endurance and leg endurance. This test was simple to set up and administer but, it was not a good metric to judge SM’s actual fitness in a combat environment. If a SM had good endurance than he or she would max the test with ease. This is not a complete reflection of what is required in a combat environment. In a combat environment the SM will be loaded down with a rifle, helmet, rucksack, plate carrier, water, and ammo which often exceeds 80 pounds. The new ACFT which is still being implemented into the forces as of the writing of this paper is a much better test as it has more events to it which measure soldier strength and ability to move while under load.

Drug-Receptor Interaction of Peptidic HIV-1 Protease: The Hydrophobic Effect-I

Abstract When a drug interacts with its receptor, the nonpolar substituent of drug and receptor proteins attract each other because they have opposite magnitude with respect to each other. X-rays structure studies reflected that the S2/S2’ pocket in HIV-1 protease enzyme are essentially hydrophobic. The residues that make up these pockets are Val-32, Ile-47, Ile-50, and Ile-84 in each monomeric [...] Read more.
When a drug interacts with its receptor, the nonpolar substituent of drug and receptor proteins attract each other because they have opposite magnitude with respect to each other. X-rays structure studies reflected that the S2/S2’ pocket in HIV-1 protease enzyme are essentially hydrophobic. The residues that make up these pockets are Val-32, Ile-47, Ile-50, and Ile-84 in each monomeric polypeptidic unit of the protease enzyme. Δπdr and ΔSASAdr have been used to measure the extent of hydrophobic interaction between peptidic protease inhibitors and receptor proteins (binding site: valine‒isoleucine; and catalytic site: glycine‒aspartic acid‒threonine) on the HIV-1 protease enzyme. For measurement of hydrophobic interaction, the molecular modeling and geometry optimization of all the inhibitors and the receptor amino acids have been carried out with CAChe Pro software by opting semiempirical PM3 methods. Log P was calculated using the atom-typing scheme of Ghose and Crippen, while solvent accessible surface area by conductor likes screening model. πd, πr, SASASd and SASASr well describe the hydrophobicities of the substituents and play the effective role for site selectivity for interaction of the drug with the receptor. Comparative study of values of Δπdr and ΔSASAdr show the order of hydrophobic interaction with respect to amino acids: Asp > Thr > Val > Ile and Thr > Val > Asp > Ile, respectively. Further, comparative study of the values of (ΣΔπdr)binding-site, (ΣΔπdr)catalytic-site, (ΣΔSASAdr)binding-site, (ΣΔSASAdr)catalytic-site shows that peptidic HIV-1-PRIs interact with binding site rather than catalytic site as binding site have lower value of ΣΔπdr and ΣΔSASAdr. Among the binding site, Val has maximum interaction than Ile, as it has lower vale of Δπdr and ΔSASAdr.

The deleterious health effects of ethanol abuse are widely known and a diversity of medical conditions appear with excessive consumption. Acute and chronic abuse have different clinical characteristics, although severe intoxications are rare among alcoholics of a long career, where the systemic complications will dominate the symptomatology. While the medical focus acutely will mostly stay on the nervous and circulatory effects, gastrointestinal complications that will come up chronically (liver, pancreas, bowel dysfunction) need proper consideration. Ethanol will affect gastrointestinal functionality through a triple action, directly on the epithelial cell and the secretory activity, by altering the motility and in the long-term scope, through promoting carcinogenesis. Medical teams dealing with acute and chronic ethanol intoxication or abuse must be aware of the multiple effects it shows, and perform a prompt diagnosis as well as appropriate intervention.

Ill-discipline has become a canker that threatens the moral fibre of institutions. This study aimed to explore the comprehensive counselling approaches that could be used to manage ill-discipline acts in Colleges of Education in Ghana. A qualitative discourse analysis study design was employed in the study. In all, 25 respondents were purposively selected from five colleges of education for the study using a semi-structured interview guide. Data collected were transcribed, coded, categorised and qualitatively analysed under themes that emerged from the analysis using the thematic approach. The study revealed that several ill-discipline acts exist in colleges of education, with perversion being the most prevailing ill-discipline act. The study recommended that the college council and management should put adequate measures in place to strengthen Guidance and Counselling units in the colleges of education. The study also recommended that college counsellors should be equipped to use appropriate counselling approaches and techniques to counsel students to desist from indulging in ill-discipline acts.

Background: Vascular thrombotic events such as pulmonary embolisms have been frequently reported in the course of SARS-Cov-2 infection. However, sagittal sinus thrombus is extremely rare, and patients may lack other appealing Covid-19 infection symptoms. Case report: 46-year-old female with past medical history of Hyperlipidemia, Hypertension presented to Emergency room with headache, chest pain, vomiting. SARS-CoV-2 IgG Antibodies were reactive. Except for elevated PTT-Lupus Anticoagulant at 50 Sec, Hypercoagulable workup was negative. The MRI venogram findings were consistent with the Dural thrombus of superior sagittal sinus. Patient subsequently developed chest pain, and Computed tomography angiography found pulmonary emboli within segmental branches of the right lower lobe pulmonary artery. Patient was managed in the ICU with Heparin and switched to Coumadin for discharged. Conclusion: The incidence of Cerebral Venous Sinus thrombus (CVST) among Covid-19 patients is inferior to 0.02%. And most of the patients lack typical Covid-19 presentations such as pneumonia. The lack of symptoms may promote the insidious course of pre-thrombotic events that lead to CVST. However more Retrospective studies are necessary to established consistent odd ratios. Due to the higher mortality associated with CVST and the ongoing of Covid-19 pandemic, we recommend a higher level of clinical suspicion.

Background: Everyone, irrespective of age, sex, colour, ethnicity, or present overall fitness level, can benefit from regular exercise. To improve one's health, one must engage in regular physical activity. People with underlying illnesses like long-term impairment can benefit from regular physical activity at the individual level, especially young women. Thus, the current study aimed to assess the prevalence and determinants of physical activity among female school-aged adolescents in the West Coast Region of The Gambia. Methods: The present study used an institutional-based cross-sectional analytical study to collect quantitative data from 384 female high school students in The Gambia. The study used a content-validated, pretested structured questionnaire that consisted of both open and closed-ended questions on physical activity. The data were processed and analyzed using IBM SPSS version 26.0. Descriptive statistics and Chi-square and/or Fisher exact test were used with a p-value <0.15 for inclusion in the logistic regression model. Adjusted odds ratios (aORs) and 95% confidence intervals were calculated, while p-value <0.05 was considered for statistical significance. Results: The proportion of female students involved in physical activity was 37.5%. The mean age of students was 18.8 years with a standard deviation of 1.7 years. Factors such as female students between 17 – 20 years (aOR:3.05, 95% C.I. (1.807 – 5.138)), father never been to school (aOR: 2.82, 95% C.I. (1.495 – 5.334)), primary education (aOR: 2.15, 95% C.I. (1.027 – 4.493)), upper basic school (aOR: 2.31, 95% C.I. (1.055 – 5.074)) and science major students (aOR: 2.21, 95% C.I. (1.203 – 4.047)) had increased odds of involving in PA. Furthermore, students who knew that exercise would strengthen bones (aOR: 2.62, 95% C.I (1.444 – 4.739)), do a planned brisk walking (aOR: 19.16, 95% C.I. (6.698 – 54.811)), basketball/football (aOR: 29.76, 95% C.I. (10.004 – 88.512)) and skipping with rope (aOR: 29.15, 95% C.I. (9.726 – 87.333)) had increased odds to involved in PA after controlling for confounders. Other factors such as students whose mother never been to school (aOR: 0.31, 95% C.I. (0.140 – 0.674)), primary level (aOR: 0.25, 95% C.I. (0.123 – 0.518)), senior secondary level (aOR: 0.42, 95% C.I. (0.189 – 0.935)), nuclear family (aOR: 0.23, 95% C.I. (0.119 – 0.458)) and extended family (aOR: 0.45, 95% C.I. (0.225 – 0.915)) had reduced odds of involving in PA. Conclusion: There is low physical activity among female adolescents in schools. For this, it is imperative that suitable interventions be implemented to raise the level of physical activity among secondary school students. A future intervention for school-aged adolescents could benefit from these findings.

The purpose of the study was to assess the socioeconomic status and levels of parental involvement on the academic performance of Junior High School Students in the Upper West Akim District in Ghana. The study adopted the quantitative approach and specifically used the descriptive survey design. Simple random sampling and purposive sampling techniques were used for the selection of schools and respondents for the study. The main instrument used for data collection was questionnaire. The Statistical Product and Service Solutions (SPSS) software version 22 was used for analysis of data gathered. The study concluded that, parents’ socioeconomic status specifically; education, occupation and income levels, is an important factor that determines the academic performance of students in the Upper West Akim District. The educational and income statuses have a positive relationship with the academic performance of students. The findings from the study also revealed that, parents who ensure that their children study at home, provide their educational needs, discuss their progress with their teachers and attend PTA meetings regularly have children who perform better academically as compared to children whose parents do not see to it that their children study at home, provide the educational needs of their children, discuss their children’s learning with teachers and attend PTA meeting regularly. It is recommended that, Considering the strong positive relationship between parental involvement and academic performance, it is recommended that government through the National Commission for Civic Education (NCCE) should educate parents, teachers and school managers on the relevance of parental involvement in the education of the child and the need for the school to create an atmosphere that would involve parents in the education of their wards. It is also recommended that, adult literacy should be enhanced by government to improve the level of education of parents in the Upper West Akim District which will go a long way to improve participation of parents in children’s education and hence improve their academic performance.

In this Research work, Silver Nanoparticles were green synthesized from Psidium guajava leaves and different Characterization techniques including UV-Visible, FT-IR, SEM and XRD were all employed to ascertain the absorption peaks, functional group, surface morphology and crystalline size of the nanoparticles respectively. These nanoparticles green synthesized were applied against four different pathogens namely, S. aureus (gram- positive bacteria), E. coli (gram- negative bacteria), C. albicans (gram- positive fungus) and Aspergillus niger and the investigation showed that the Silver nanoparticles synthesized were potent against the selected pathogens. From the UV-Vis spectral analysis, it was observed that highest absorption peaks appeared at 400nm and 500nm reflecting the surface plasmon resonance of silver Nanoparticles from guava leaves which is characteristic of Silver Nanoparticles. From the FT-IR spectrum of the sample under studied, the peaks 3416.85 cm-1, 2923.51 cm-1, 1618.95 cm-1, 1384.49 cm-1 and 1033.63 cm-1 were observed where the absorption band at 3416.85 cm-1 corresponds to the stretching due to N-H, while the band at 2923.51 cm-1 is associated with C-H stretch of alkane and O-H stretching. The peak at 1618.95 cm-1 shows C=C stretching, 1384.49 cm-1 reveals the existence of C-H bending and 1033.63 cm-1 depicted C-O stretching. The SEM analysis revealed the shape of the nanoparticles as being spherical while XRD result admits that the average size of the green synthesized Ag NPs was 45.5 nm using the Scherer’s formula. Augmentin was used as control at concentration of 300μg/L throughout antimicrobial studies. Different concentrations of 100, 200, 300, 400 and 500μg/L of Silver Nanoparticles were tested against each pathogen. It was discovered that with increase in concentrations of Silver Nanoparticles of all the pathogens, there generally appeared to be increase in inhibition zone. At higher concentration of 500μg/L, the zones of inhibition were in the following order; 22.50 mm, 17.00mm, 15.44mm, and 13.23mm for E. Coli, S. aureus, C. albicans and Aspergillus niger respectively. For each concentration investigated, E. coli, demonstrated higher zone of inhibition as opposed to all other pathogens investigated in this research.

Resistance exercise is the performance of physical exercises designed to improve strength, muscular, endurance, hypertrophy, and neuromuscular efficiency with the use of weights (Braith & Stewart, 2006)[1]. Resistance exercise has long been utilized for its beneficial health qualities and propensity to elicit certain desired physiological changes (Fry, 2004)[2]. There has been a recent, and significant, increase in resistance exercise activity in American adults (NCHS, 2018)[3] attributable to factors such as autonomous compulsion and self fulfilment to extrinsic factors like health and physical appearance (Fisher et al., 2017; Heinrich et al., 2014; Ingledew & Markland, 2008)[4,5,6]. As such, there is an ever-increasing need for educational material regarding resistance exercise, its benefits, purpose, and manner in which it should be conducted. Purpose- to (a) provide resistance exercise-based educational material regarding the background and rationale behind resistance training; (b) to provide a specific resistance-based exercise program to elicit strength gain; (c) to provide individuals with the knowledge to safely and effectively engage in said program; and (d) to provide the participant with expected physiological adaptations to completing the program. Methods- Two 6-week, 5-day per week resistance exercise programs – with a brief nutritional guide accompaniment – are outlined for a hypothetical participant, age 25-40, of moderate experience with fitness training, and with the goal of strength gain and moderate fat loss as a secondary goal. Results- Anticipated benefits of the program include: increased maximal strength caused by training above 85% 1RM for 2-6 sets of 1-6 reps; increased synergistic muscle groups strength which will contribute to improved prime mover strength; hypertrophy of skeletal muscles throughout the body, induced by lifts of 67-85% 1 rep max (RM) for 3-6 sets of 6-12 reps and increased resting energy expenditure (basal metabolic rate) accompanied by improved body composition. Conclusion- Continued progression though this protocol with modifications to resistance include potential improved running speed, explosive power potential, and other anaerobic sport performance factors, as well as enhanced neuromuscular efficiency associated with increased prime mover force production capabilities.

Assessment of Microbiological Quality of Ready to Eat Food Served in Ships Along Warri, Koko and Port Harcourt Water Ways, Nigeria

Abstract Background: Food borne outbreaks have been associated with sourcing unsafe food. Therefore, the first preventative strategy should be to source safe food. Even if the sourced food is safe, measures need to be put in place to ensure that it remains safe during the transfer, storage, preparation and serving activities that follow. An understanding of the ship food supply and transfer chain will help to illustrate the points at which the food can become contaminated en route to the point of consumption. Objectives: The study was conducted in selected sea port in the core Niger Delta to assessed the microbiological quality of food served at different ship galley to crew and passengers and compered it to standard. Methods: Samples of food were taken from three (Port Harcourt Area one (PHSP), Warri (WSP) and Koko (KSP)) seaports within the South-South zone for laboratory analysis to uncover food spoilage microorganisms capable of causing disease outbreak among ship which could result to Trans border diseases. Eleven samples of different ready to eat food were collected from the locations, which included cooked rice; fried fish, irish potato porridge, vegetable soup, griki, pepper soup, fried irish potato, salad and bread were collected randomly. The samples were prepared and analyzed using standard procedures. Mean viable counts of aerobic and anaerobic bacteria were determined, ranging from (13×103cfu/g to 78×104 cfu/g) for ready to eat food. Results: Based on the finding KSP I, KSP J and KSP K food samples had the highest bacterial contamination on food while WSP F, WSP G and WSP H food samples had the least with the following isolates Salmonella spp, Nocardia spp, Shigella spp, Listeria spp, Bacillus cereus, Leuconostoc spp, Acinetobacter spp, Acetobacter spp, campylobacter spp, Clostridium spp and Vibrio spp [...] Read more.

An unhealthy dietary habit leads to excess calorie consumption (overnutrition) or inadequate supply of one or more essential micronutrients (undernutrition).This nutritional imbalance is assessed by Anthropometric measurements, Biochemical estimations, Clinical examination and assessment of Dietary intakes. Anthropometry is an inexpensive, rapid and non-invasive method that provides details on different components of body structure and is highly sensitive to the broad spectrum of nutritional status. Hence, it has always been an important tool for screening and early diagnosis of malnutrition. Undernutrition in below 5 year children is life-threatening epidemic contributing to about 45% of under 5 child deaths. Children with Severe Acute Malnutrition (SAM) are nine times more likely to die, compared to their healthy counterparts. Therefore, early and accurate diagnosis of children with SAM is crucial for its management and prevention of morbidity and mortality from the same. SAM is defined as weight-for-height Z scores (WHZ) below -3SD of the median or a mid upper arm circumference (MUAC) of <115mm in children of 6-59 months age. The cut-offs for MUAC and WHZ are scientifically approximated to each other and both are used to diagnose children with SAM (Severe Wasting). However, the research findings from various countries revealed that the agreement between WHZ and MUAC is poor as both indices classify the children with SAM differently, with a small overlap, which varies greatly among countries. These discrepancies have an implication when using either one alone for measuring the prevalence of acute malnutrition. Therefore, it is pertinent to adopt both WHZ and MUAC indices to assess the burden of severe acute malnutrition (SAM) in the community.

This study raises the problem of the non-repayment of agricultural credits by producers who are members of the Community Growth Mutual (MC2), in this period of COVID-19. It questions the economic mores in force in most member countries of the Organization for the Harmonization of Business Law in Africa (OHADA), where credit has become difficult for small rural farmers; And refers to the theory of the vicious circle of poverty, which advocates an indispensable recourse to foreign capital in the event of financial breakdown, as a means of increasing capital. Since the capital of rural producers remains insufficient and their possibility of reinvestment decreases, then becomes zero because of agricultural credit. To understand the factors of the non-repayment of these credits, data were collected from 100 agro-sylvo-pastoral producers of the Bayangam group (West-Cameroon) of both sexes, aged at least 18 years, having obtained an unpaid credit from the MC2 since 2019, and a manager of this microfinance institution. After analysis, it appears that beyond overproduction and anti-COVID-19 measures that lead to the missale or fall in prices on the market, the conditions of access to credit, the non-possession of acceptable guarantees, the misuse of the object of credit and the practice of financial cavalry by the borrower, as well as the rigidity of the procedures for prosecuting debtors significantly explain this non-repayment. It is associated with determinants such as age, level of education, marital status, type of agricultural activity of the debtor. Hence the need for flexibility of microfinance institutions vis-à-vis rural agro-sylvo-pastoral producers, who are severely affected by the economic shock of the COVID-19.

A 75-year-old female is referred for evaluation of a progressive leg swelling. Angiological and MRI evaluation show the presence of inflammatory tissue surrounding the aorta and the left iliac vessels, causing significant stenosis. Upon suspicion of retroperitoneal fibrosis, we actively seek for secondary causes such as malignancies, autoimmune diseases and infections, as well as IgG4-related disease. All investigations result negative and we make the diagnosis of idiopathic retroperitoneal fibrosis. Steroid therapy was started and we observed a rapid amelioration of symptoms and radiological disappearance of the inflammatory tissue around the aorta.

BDNF, A Focus to Major Depression

Abstract Major depressive disorder is characterized, among other symptoms, by depressed mood and anhedonia associated with a high rate of suicidal ideation. In recent years, research has shown reduced expression of the brain-derived neurotrophic factor (BDNF) in limbic areas of individuals with depression.

Major depressive disorder is characterized, among other symptoms, by depressed mood and anhedonia associated with a high rate of suicidal ideation. In recent years, research has shown reduced expression of the brain-derived neurotrophic factor (BDNF) in limbic areas of individuals with depression. This reduction of BDNF is reversed by antidepressants in animal models of stress. Stress is one of the main triggers of mood disorders such as depression. Also, administration of BDNF increases the number of serotonergic fibers and serotonergic innervation, indicating an increase of serotonin in the synaptic cleft by this neurotrophin. Thus, BDNF appears to be one of the targets of antidepressant drugs for the increase of monoamines and remission of symptoms of major depression. The purpose of this review was to show the evidence that indicates BDNF as a molecular substrate for vulnerability to depression and the response of this substrate to the antidepressants.

Background: Annual influenza outbreaks constitute a major public health concern in the United States. But this health burden appears dwarfed by the impact of COVID-19. Our aim is to quantify the excess mortality attributable to COVID-19, compared to previous influenza seasons. Methods: We retrospectively compare weekly mortality figures attributable to influenza and pneumonia in the United States from 2013 to 2019 with corresponding figures attributable to influenza, pneumonia, and COVID-19 from 2019 to 2021. We utilize a difference in differences regression methodology to estimate excess mortality observed in 2019-21 compared to 2013-2019. Results: Mortality patterns attributable to influenza, pneumonia, and COVID-19 differ significantly from the 2013-19 experience. Notably, distinct, aperiodic mortality waves occur in the 2019-2021 window, and mortality is well in excess of what is observed in typical influenza seasons. Conclusions: The COVID-19 pandemic has led to considerable excess mortality in the United States, and has strained public health resources. One might expect that the mortality waves observed during the pandemic will be damped by increasing levels of vaccination, and prior infections.

Objective: The study employed a quasi- experimental design of a single group pre-test post-test. The purpose of the study was to assess the locomotor and object control skill development levels of 6-8-year-old basic school pupils in Kwahu Afram Plains South district of Ghana The target population for the study comprised all 6-8 years old primary school pupils in Tease in Kwahu Afram Plains in the Eastern Region of Ghana. Convenient and stratified sampling techniques were used to select 57 pupils made up of thirty-seven (37) boys and twenty (20) girls. The instrument used for this study was Test of Gross Motor development (TGMD-2). Descriptive frequencies were used to analyse the data. The study revealed that pupils demonstrated high level of perfection with reference to their locomotor skills in the various physical activities with most responses on their skill execution mostly ranked between often and always. The study also indicated that pupils were able to perform locomotor skill activities well. The study also concluded that pupils were not really equipped with motor skill and were not able to execute motor skill activities correctly during physical activities with responses on motor skill mostly ranked between rarely and often. It is recommended that lower and upper primary school teachers in Kwahu Afram Plains South district should be equipped with the prerequisite skills to enable them to teach motor skills development effectively. It is also recommended that more qualified physical education personnel should be sent to the basic level in Kwahu Afram Plains South district to teach physical education since motor development and skill acquisition develop the habit of the active lifestyle of individuals.

Magnetic iron nanoparticles (Fe3O4) were synthesized and characterized using Fourier Transformed Infrared ((FT-IR), UV-Visible spectrophotometer, Scanned Electron Microscopy (SEM) equipped with an Energy Dispersive X-ray spectrometer (EDX), and X-ray Diffraction (XRD). The synthesized nano catalyst was used in the transesterification of mahogany seed oil with methanol. The optimized reaction conditions gave a reaction yield of 88% at a catalyst concentration of 1.5% wt., a volume ratio of methanol to oil of 5:1, a reaction temperature of 60 °C, and a reaction time of 120 minutes. The Fe3O4 nanoparticles was regenerated from the mixture and reused for various circles by applying the optimum conditions obtained during the present study. The results showed that the biodiesel yield decreased by increasing the number of cycles when the regenerated catalyst was used. However, good conversion (81.9%) was obtained up to the 5th cycles. The elemental analysis of the synthesized magnetic iron nanoparticles Fe3O4) revealed the highest proportion of iron with 64.37 and 74.40% for atomic and weight concentration respectively, followed by oxygen with 34.27 and 24.50% for atomic and weight concentrations respectively. It could be concluded that the synthesized nano catalyst would serve as an excellent catalyst for the transesterification of vegetable oils.

Essentiality of water sustain life, and a satisfactory supply must be readily available to promote health, prolong life expectancy and prevent diseases. This study assesses the sources and quality of drinking water in Piwoyi community of Federal Capital Territory, Abuja, Nigeria. Thirty-five (35) Boreholes and Two (2) Sachet water were identified sources of drinking water in Piwoyi Community. Six Samples (5 Boreholes and 1Sachet water) were selected at random and analyzed in the laboratory. The Physicochemical parameters examined include electrical conductivity (EC), pH, temperature, turbidity, dissolve oxygen (DO), chloride, total hardness, alkalinity, nitrate, calcium, magnesium, phosphate, phosphorous, sulphate, sodium, potassium, fluoride, bicarbonate, nitrate-nitrogen, nitrite, copper, iron and zinc; and Microbiological parameters include Coliforms, E-coli and Faecal Strep. The results of analysis shows significant concentration of physicochemical and microbiological parameters in the samples of water analyzed according to Nigerian Standard for Drinking Water Quality thereby makes the water unsafe for drinking. Drinking from these sources of water will pose serious health risk to the people of Piwoyi Community. Therefore, the study helps to identify the contaminated locations as well as assist to follow emerging remedial measures toward controlling the contamination source in the community. It also recommends continuous monitoring and enforcement of environmental violations, aggressive sensitization on water sanitation and hygiene; adequate purification of water at domestic level; and government support on potable water supply and establish reasonable management strategies for sustainable water quality protection toward protecting public health.

Background: Cancer surveillance data provide information on the incidence and trends of cancer in the population level. Analyzing cancer trends according to these characteristics plays an important role in cancer surveillance. Knowledge of the causes of cancer allow better prevent the appearance of it. A large number of epidemiological evidence supporting the effect of smoking on the causes of cancer there is strong evidence supporting a role for smoking in the etiology of cancers. Alcohol appears to interact with the tobacco significantly and can be considered a risk factor in the development of cancers. Obesity which is now well recognized as a public health problem increases the risk of developing cancers. All these factors are characterized by uncertainty, complexity and imprecision. Methods: In this study, we propose an analysis of these factors based on the principles of fuzzy logic inference system. The data were collected from WHO data. As this technique addresses the uncertain, its application in this area is perfectly adequate. Results: A database is established, after the analysis system is done, it will be possible to read the prevalence of cancer by introducing randomly the values in inputs variables. Conclusion: like cancer has become a national scourge, this application allows predicting the impact of it just from the introduction inputs variables such as BMI, degree of physical activity, tobacco and sex.

The first visualizations of the structures of the sheep's reproductive system, whether of the uterus or ovaries, were performed through exploratory laparotomies, laparoscopies or through materials obtained in slaughterhouse, being possible to evaluate only what was happening at that moment in the estrous cycle. With the emergence of ultrasound from the 90s, it became possible to dynamically monitor what happened at each moment of the estrous cycle at different times of the year, without having to slaughter the females. Because it is a non-invasive technique and the stress caused by its use is very low, it is increasingly necessary to use ultrasound in sheep, either for pregnancy diagnosis or for multiplying herds using biotechnologies, which the ultrasound examination becomes indispensable to obtain the best results. This review aims to describe the main advances in the study of the estrous cycle of sheep with the help of ultrasonography and its influence on the productive efficiency of the herd.

Unfortunately, it is not disaster recovery, high availability, or cloud technologies that are inherently difficult to understand, but rather the action of implementing them for software applications that is difficult. The unique method of implementation for a microservices architecture is explored. Regulatory compliance doesn’t stop just because an effective disaster recovery requirement is tough to satisfy for infrastructure unique to sleek microservices. The high-availability location transparency bliss offered by a cloud solution is appealing to a security engineering department. However, the headache starts when the technology presents a handful of undesirable surprises that leak RESTful microservices to the outside world. These are the challenges that post-SOA cloud-resident robustly scalable applications will need to address and overcome. The goal is to explore several popular methods of accomplishing these tough objectives so that engineers can further research the most practical solution. An innovative implementation that leverages Service Bus relays as an elegant disaster recovery solution while enforcing a strict subnet where RESTful microservices solely live will be discussed. The curiosity lies in the atypical experimentation beyond basic gateways and the facility of using such simplicity while still answering day-to-day software development infrastructure challenges for applications we build. Resilient full-service web proxy service crashes and delivery latency switches by harnessing the microservices pod health will also be discussed [1].

The complexity of manufacturing photolithography has increased significantly. The increase in the level of integration has driven smaller feature-sized integrated circuits (ICs). The evolution in stepper technologies has been geometric. This has enabled the printing of printed ICs with a 45 nm feature size. Improvement in lithographic technology is moving towards 32 nm. This feature-size roadmap poses many challenges to semiconductor manufacturing technology. Advanced photomask synthesis, high-NA steppers, and computational lithography are some examples of the solution space. Optical proximity correction (OPC) and model-based optical proximity correction (MBOPC) are subsets of this solution space. OPC has matured significantly and is the de facto solution for manufacturing photomasks up to the 65 nm node. The OPC technique has been further refined as model-based OPC and has been applied to advanced printing technology of 45 nm. The OPC solution for 45 nm technology has limitations of mask rule check (MRC) and manufacturability restrictions. These restrictions are inevitable in OPC and MBOPC solutions because of the limits in lithographic technology. The technology evolution towards 32 nm has equally challenged the non-linear treatment of wafer-level problems in OPC solutions. PBOPC has limitations in reducing the wafer optical proximity error of the granny's issue, edge placement, mask rule check, etc. PBOPC also has limitations in reducing the mask error enhancement factor. With all these challenges, it is still a formidable solution methodology to address the wafer and mask level issues. Such a formidable solution architecture can result in a limited number of PBOPC solutions. This text looks at the performance of advanced PBOPC features on exposure tuning and the effects of higher-order wafer and aerial image effects. This text also discusses the performance of continuous process correction of masks, lenses, and scanners.

Generative AI refers to deep learning technology that can automatically produce original text, images, audio, video, and other outputs. With its emerging capabilities, Generative AI can radically change the dynamics of key operational processes in most industries. In this document, we illustrate how it is possible to integrate Generative AI technologies into the Financial Reporting System (FRS) of a corporation. The integration will allow the FRS to deliver on demand concise and lucid insights to its associated users on what is happening in the corporation and different aspects of the corporation performance assessment, such as its liquidity, solvency, profitability, organizational structure, and share buy back decision. The integration will also facilitate the delivery of what-if analyses associated with different strategic and tactical decisions taken by the corporation management, such as capital budgeting and profit distribution decisions. The unique added value of several attributes of these insightful analytics is automating the responses to ongoing requests of the FRS users on the corporation. Generative AI capabilities are rapidly expanding. The integration can be applied not only for the corporate FRS but any FRS at the national or global levels delivered by a central bank or an accounting standards setter. Any of these FRS can be made into a unique “hub” for the integrated Generative AI technologies. An equally innovative possible generalized integration could put any corporate process at the center and its supporting FRS tasks and deliverables in its periphery.

The effects on the elderly are disproportionately Alzheimer’s disease (AD) is one of the most prevalent and chronic types of dementia. Alzheimer's disease (AD), a fatal illness that can harm brain structures and cells long before symptoms appear, is currently incurable and incurable. Using brain MRI pictures from a publicly accessible Kaggle dataset, this study suggests a prediction model based on Convolutional Neural Networks (CNNs) to help with the early detection of Alzheimer's disease. Four levels of dementia have been applied to the 6,400 photos in the collection: not demented, slightly demented, moderately demented, and considerably mildly demented. Pixel normalization, class balancing utilizing data augmentation techniques, and picture scaling to 128×128 pixels were all part of a thorough workflow for data preparation. To improve the gathering of spatial dependence in volumetric MRI data, a 3D convolutional neural network (CNN) architecture was used. We used important performance measures including F1-score, recall, accuracy, precision, and log loss to gauge the model's effectiveness. A review of the available data indicates that the total F1-score, accuracy, recall, and precision were 99.0%, 99.0%, and 99.38%, respectively. The findings demonstrate the model's potential for practical use in early AD diagnosis and establish its robustness with the help of confusion matrix analysis and performance curves.

Seamless integration of information in organizations promotes not only the operational efficiency but also the quality of decisions made by managers. Real-time decision support systems enable organizations to evaluate organizational changes immediately and ideally gives a hint of problems before they even appear in the organization. Such real time systems are nowadays regarded as the front-line solutions for managing organizations effectively. The technological possibilities seem not to conquer management. For most companies the data is still dealt with traditional solutions, data is collected and reports are generated to evaluate the past occurrences which only gives information on what has happened in the organization. The problem with these non-real-time systems is the reflection of organizational condition very late. These are the common rear-mirror descriptions for what already has been. Managers are receiving information from their organizations too late and often too little to make optimal decisions. Is it not possible to manage operations in real-time? Is real-time decision support really needed? If so, why most organizations still rely on traditional reporting systems.
