The accurate estimation of Individual Wave Components (IWC) is crucial for automated diagnosis of the human digestive system in a clinical setting. However, this process can be challenging due to signal contamination by other signal sources in the body, such as the lungs and heart, as well as environmental noise. To address this issue, various denoising techniques are commonly employed in bowel sound signal processing. While denoising is important, it can increase computational complexity, making it challenging for portable devices. Therefore, signal processing algorithms often require a trade-off between fidelity and computational complexity. This study aims to evaluate an IWC parameter extraction algorithm that was previously developed and reconstruct the IWC without denoising using synthetic and clinical data. To that end, the role of a reliable model in creating synthetic data is paramount. The rigorous testing of the algorithm is limited by the availability of quality and quantity recorded data. To overcome this challenge, a mathematical model has been proposed to generate synthetic bowel sound data that can be used to test new algorithms. The proposed algorithm’s robust performance is evaluated using both synthetic and clinically recorded data. We perform time-frequency analysis of original and reconstructed bowel sound signals in various digestive system states and characterize the performance using Monte Carlo simulation when denoising is not applied. Overall, our study presents a promising algorithm for accurate IWC estimation that can be useful for predicting anomalies in the digestive system.

Anaphylaxis can be associated with hemodynamic shock, which requires the early initiation of adrenaline as part of its management. Cardiogenic pulmonary edema is a frequent entity in emergency services with increased mortality in patients with acute coronary syndrome. The case report presents the case of a 55-year-old male patient who entered the emergency department with a non-ST-segment elevation myocardial infarction (NSTEMI) associated to pulmonary edema and anaphylaxis. During his stay in the emergency room, he had an anaphylactic reaction to dipyrone (metamizole) used for pain control. The patient presented signs of acute pulmonary edema, a hypertensive urgency after the use of adrenaline for the management of anaphylaxis.  There was doubt as to whether the dyspnea was of anaphylactic or cardiogenic origin, so an emergency ultrasound was performed, which suggested a bilateral pattern B.  This allowed timely management of ventilatory failure with systemic nitrates, diuretics, and oxygen therapy, which controlled blood pressure and resolved ventilatory failure. Subsequently, he was transferred to an institution with a hemodynamic service for the management of NSTEMI. We highlight the utility of emergency ultrasonography for immediate decision-making and the low prevalence of anaphylactic reaction in a patient with NSTEMI leading to acute pulmonary edema.

In this paper, we found a new model for a compact star with charged anisotropic matter distribution considering the generalized Chaplygin equation of state. The Einstein-Maxwell field equations have been solved with a particular form of metric potential and electric field intensity. The plots show that physical variables such as radial pressure, energy density, charge density, anisotropy, radial speed sound, and the mass are fully well defined and are regular in the star's interior. We obtained models consistent with stellar objects such as GJ 832, LHS 43, SAO 81292, GJ 380, GJ 412, and SAO 62377.

Acupuncture is an alternative medicine, actually it has had a greater acceptance in our continent being use for multiple therapeutic purposes. Although it is a minimally invasive procedure it is not exempt from complications, most common minor complications such as infections or local pain have been described, as well as less frequently but potentially fatal complications such as subarachnoid hemorrhage and tension pneumothorax. We report a case of pneumothorax secondary to acupuncture in a patient who was treated for carpal tunnel syndrome.

Meigs’ syndrome is a rare triad of a benign ovarian fibroma (or fibroma‑like tumor), ascites, and pleural effusion that resolves after tumor resection. A 53‑year‑old multiparous woman presented with progressive exertional dyspnea and right‑sided pleuritic chest pain. Respiratory and cardiac evaluations were initially unrevealing. Bedside assessment identified mild right basal dullness, and point‑of‑care abdominal ultrasound demonstrated mild free fluid and a solid right adnexal mass. Chest radiography confirmed a small right pleural effusion. Without computed tomography and without diagnostic paracentesis or thoracentesis, Meigs’ syndrome was suspected. The patient underwent laparotomy with total abdominal hysterectomy and bilateral salpingo‑oophorectomy. Histopathology confirmed an ovarian fibroma. Postoperatively, symptoms resolved dramatically, and follow‑up imaging demonstrated complete resolution of the pleural effusion and ascites. This case highlights the importance of considering gynecologic etiologies in unexplained pleural effusion and dyspnea, especially when accompanied by abdominal distension or pelvic pressure.

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. External jugular vein involvement due to F. necrophorum is rare and should be considered in patients presenting with septic emboli.

This study aimed to evaluate the Social Studies Curriculum for Senior High Schools in Ghana to determine whether the subject has attained its goal(s) or not, using Stake’s Countenance Evaluation Model. The study took place in the Asante Akim North District. The population for study were all Social Studies teachers and students in the district. The multi-stage sampling technique was adopted for the study and the sample size was 120, made up of 100 students and 20 teachers. The concurrent mixed method approach was adopted. The main instruments used for collecting data were questionnaires, interviews (focus group and unstructured interview), observation and documentary analysis. Quantitative data were tabulated, organised, analysed and interpreted to draw sound conclusions and generalisations. The data were presented in the form of tables and percentages. Words were used to interpret the tables and percentages for easy understanding. The qualitative data responses were described and explained in the form of themes. Sometimes responses were quoted verbatim to authenticate claims made. The study looked at the congruence between what was intended to occur and what was observed before and during the implementation of the curriculum in the Asante Akim North District. On the transactions, it was revealed that teachers in the district communicate the problem the topic seeks to address and the specific objectives to the learners during instruction. Also, teachers varied their teaching methods, techniques and strategies. However, teachers failed to take students out on field trips. Also, they failed to use video documentaries to deliver their lessons inhibiting students’ creativity as they are denied the opportunity to explore and get first-hand information to build up knowledge and develop the needed attitudes and values. From the findings, it is therefore recommended that the National Council for Curriculum and Assessment should increase the time allotted to the teaching of Social Studies at the SHS level from 3-periods of 40 minutes a week to 5-periods of 40 minutes a week to give teachers and learners ample time to discuss, debate, digest and solve problems during instructional hours to enable the goal of the subject attained.

The purpose of the study was to evaluate of Social Studies Teachers Knowledge in Nature, Goals, and Objectives in the Lesson Presentations The study adopted qualitative research approach. Data were collected through the use of individual interviews, observation and focus group discussions for triangulation purposes. Purposive, convenient and simple random sampling techniques were used to select the schools, teachers for the study. In all, seventeen (17) Social Studies teachers were selected from six (6) Senior High Schools. The study revealed that teachers were grossly deficient about the goals of Social Studies. To improve this system, it is recommended that the researchers suggests that the highest priority should be given to the training and development of a new breed of educator who are vocationally competent and academically sound. This can be done by heads of institutions to allow teachers who specialise in their respective areas to teach those subject areas at the various levels of education particularly Social Studies at the High school level.
