Mathematical modeling plays a central role in infectious disease epidemiology, shaping outbreak response strategies and informing public health policy. The COVID-19 pandemic demonstrated the value of these models but also exposed persistent limitations related to data fragility, lack of transparency, limited stakeholder engagement, and insufficient consideration of social and political contexts. Rather than critiquing modeling as a discipline, this perspective argues for a reorientation of infectious disease modeling toward a more responsive, equity-centered, and participatory paradigm. We propose a conceptual framework built on three interrelated principles: adaptability through real-time data integration, transparency via open-source and reproducible practices, and relevance through interdisciplinary and co-produced model design. Drawing on illustrative examples from COVID-19 and dengue control efforts, we highlight how integrating behavioral dynamics, local knowledge, and policy feedback can improve model usefulness and public trust. Reconceptualizing models as dynamic systems of inquiry rather than static forecasting tools can enhance decision-making and promote more equitable and effective responses to future public health emergencies.

Complexity Leadership Theory (CLT) is a new and revolutionary concept in addressing healthcare crises worldwide. Its relevance and applications were tested during the COVID-19 pandemic. However, no definite and encompassing research was done to apply it to nursing leadership. Thus, this study examines CLT integration into nursing leadership to address the challenges posed by the pandemic. Through a systematic review of literature from PubMed, Scopus, and Web of Science, relevant studies were analyzed to determine how complexity leadership theory was defined, conceptualized, and operationalized within nursing leadership context. The findings reveal that traditional hierarchical leadership models are insufficient in a dynamic crisis environment like the pandemic. Instead, CLT’s framework which encompasses adaptive, administrative, and enabling leadership facilitates innovation, resilience, and effective interprofessional collaboration. Nurse leaders employing these strategies are better positioned to manage resources limitation, foster shared decision-making, and implement technological advancements in rapidly changing healthcare settings. Overall, this study underscores the potential of complexity leadership theory to transform nursing leadership practices by promoting continuous learning and empowerment, thereby enhancing crisis response and preparedness for future pandemics.

<b>Background:</b> The COVID-19 pandemic posed significant psychological challenges to frontline healthcare workers (HCWs), including anxiety, stress, and emotional strain. <b>Aim</b>: This study investigates the psychological impact on HCWs during the pandemic and explores coping strategies employed to manage distress. <b>Methods</b>: 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. <b>Results</b>: 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. <b>Conclusion</b>: 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.

Respiratory virus co-infections have been suggested to happen frequently and exacerbate patients’ conditions, but little is known about the detailed rates and the combinations of viruses during the COVID-19 pandemic period. A total of 255 symptomatic patients who underwent multiplex PCR tests were analyzed, and it was found that 6 (6/255=2.4%) patients were infected with multiple viruses. The patients ranged in age from 1 to 38 years, and one female patient was pregnant. Of the 6 patients, 4 had fever, and 5 had human rhinovirus/enterovirus and another virus. These data suggested that the rate of respiratory virus co-infection was low, and the combination of SAS-CoV-2 and other viruses was rare even during the COVID-19 pandemic.

The COVID-19 pandemic has had a significant impact on individuals worldwide, affecting not only their educational futures but also their mental health. This paper aims to explore college students' perceived barriers to accessing mental health services during the pandemic. The study finds that there is a significant difference between stigma-related and non-stigma-related barriers, with non-stigma items being rated higher on average. The most commonly reported non-stigma barriers include wanting to solve the problem independently, financial constraints, and the belief that the issue will resolve itself. Stigma-related barriers include feeling embarrassed or ashamed, concern about having a mental health problem on medical records, and fear of being seen as crazy or weak. This research sheds light on the challenges students face in seeking mental health care during the pandemic and highlights the need to address these barriers.

<b>Background:</b> There is paucity of data on health-related quality of life (HRQoL) among Health Information Managers/Health Record Officers (HROs) in the Nigeria health system. Hence, this study investigated the impact of the COVID-19 pandemic on health-related quality of life (QoL) among HROs in Obafemi Awolowo University Teaching Hospital Complex (OAUTHC), Ile-Ife, Nigeria. <b>Methods:</b> A cross-sectional study was conducted in the University Hospital, where a total of 52 health record officers were purposively sampled. Relevant data were collected using the Short Form survey (SF-36v2) questionnaire. One-way ANOVA was used to determine mean group differences across the nine and the two QoL (physical and mental) summary domains based on respondents’ socio-demographics, while level of significance was set at 0.05. <b>Results: </b>All the QoL sections of the instrument used yielded an α-Cronbach’s score of > 0.70. Analysis of some QoL physical component dimensions showed that; Bodily pain (BP) was found to be significantly (P=0.032) associated with marital status, Physical functioning (PF) with gender (P=0.023), and general health (GH) with age group (P=00.025) and highest level of education (P=0.023). On the other hand, mental health component analysis revealed that Social Functioning (SF) was associated with age group (P=014), Role limitation (RE) with marital status (P=0.048), highest level of education (P=0.048) and years of service (P=0.015) etc. <b>Conclusion:</b> The QoL among HROs studied was generally above average, and demographic characteristics such as age, gender and marital status significantly influence QoL. Health managers and stakeholders should consider some of the factors identified in managing HROs.

Background:</b> The COVID-19 pandemic disrupted routine osteoporosis care due to clinic closures and limited in-person consultations. Telehealth emerged as an alternative model enabling remote care delivery and monitoring. However, previous reviews on telehealth either did not include the pandemic period or had a limited focus in scope. Evidence synthesized specifically for osteoporosis care during the pandemic is needed but lacking. <b>Methods:</b> We systematically searched PubMed, MEDLINE, EMBASE, PsycINFO, Web of Science, and CINAHL for studies on telehealth for osteoporosis published between January 2021 and March 2023. Five studies met the inclusion criteria of: osteoporosis population, telehealth intervention, and COVID-19 pandemic timeframe. Data was extracted on study characteristics, COVID-19 outcomes, osteoporosis status, telehealth purpose, patient satisfaction, and clinical outcomes. <b>Result:</b> The five studies showed telehealth was used for monitoring data, delivering test results, adjusting medications, and assessments. Osteoporosis prevalence among telehealth users ranged 30-100%. High patient satisfaction was reported with telehealth versus in-person care. No major differences occurred in medication delays or fractures between telehealth and in-person groups. <b>Conclusion:</b> This review found telehealth enables effective osteoporosis care and monitoring during the pandemic, with high patient and provider satisfaction. However, more robust randomized controlled trials are needed to establish stronger evidence around telehealth's impacts on clinical osteoporosis outcomes. <b>Implications:</b> Though promising, further high-quality studies will help clarify telehealth's role in improving osteoporosis care and outcomes. Findings inform guidelines on integrating telehealth into routine management. Evidence on user perspectives optimizes telehealth implementation policies.

The pandemic of the SARS-CoV2 (COVID-19) that was declared by the World Health Organization (WHO) on 11 March 2020 is still ongoing. One of the early recommendations from CDC and other international agencies is the seasonal influenza vaccination to decrease the effects and burden of COVID-19 pandemic. This review suggests that during COVID-19 pandemic vaccination against seasonal influenza should be conducted all over the year, even for young age groups, because of several reasons. First, the complications of seasonal influenza, especially pneumonia, could increase the burden on the saturated healthcare systems worldwide. Second, the resemblance of symptoms and signs of both seasonal influenza and COVID-19 will difficult diagnosing and isolation of COVID-19 patients. Third, it has been postulated that there is a cross immunity between seasonal influenza and COVID-19.

This review aimed to analyze some problems and challenges that emerged from the COVID-19 pandemic since it has affected all global business sectors. During the pandemic, remote work was increased in response to social distance requirements to decrease the transmission of disease. In addition, increased delegation, teamwork, supply chains, sales activities, and business operations have all been disrupted. Many challenges have emerged in the management of organizations due to the pandemic including the lack of direct contact as the lockdown made many people work from home and placed restrictions on movement and travel and uncertainty about the future. The healthcare system was also affected by the COVID-19 pandemic and faced several difficulties including increased demand for medical supplies and personal protective equipment, a greater need for nurses and other skilled healthcare professionals, and increased pressure on healthcare facilities, emergency services, and critical care departments. These challenges have created some opportunities in the management systems of healthcare organizations and other sectors. It is recommended for leaders prepare and continuously work proactively to be ready for unexpected future crises. Risk management and planning for any unexpected situation are among the very important aspects of organizational management.

This article seeks to relate (trans)generational issues with the phenomenon of sociodromology and education in the COVID-19 pandemic period that began globally in the first months of 2020 and 2021. To make such crossings possible, we will initially present under which aspects we are addressing the term generation, and its respective phenomenological development, transgenerationality. Once these concepts have been properly presented it is also necessary to relate those information with the generations that are currently living within educational environments, especially schools. After such an exposition, we will present the theory that contemplates the vector of acceleration and its respective consequence for humanity. Sociodromology emerges as a theoretical instrument that makes it possible to critically glimpse how the speed of machines has dictated our lives, having a perverse facet of exclusion that determines which groups may be able or unfit at their pace. Finally the text concludes its reflection on the current educational context using the critical tools of socio-pedagogy, which views the subjects who are involved in the educational process as representatives of an even greater order in the world, which transcends schools. In this perspective, education as a pillar of knowledge acquisition should be revised in addition to its pre-determined role in society and should form individuals who could change the world and their communities.

As COVID-19 pandemic spreads worldwide, universities and academic institutions were forced to shift their face-to-face education to online learning since spring 2020. This shift was termed “emergency remote education or learning”, caused many distractions to students, and posed many challenges for both assessment and examination systems and practices at our Zhejiang University-University of Edinburgh (ZJU-UoE) Biomedical Science Institute, like other educational institutions worldwide. This necessitated the development of alternative and effective approaches and procedures to teach students, and several changes and adaptions of assessments and examinations at ZJU-UoE institute. In this article, we described the implications of the COVID-19 pandemic for student assessment systems and practices at ZJU-UoE Institute. The article is particularly reflecting on alternative approaches and strategies that we have developed at ZJU-UoE institute to change and adapt student assessments and examinations during COVID-19 pandemic. These changes involved developing general examination strategies and settings, including online (MCQ-type) test exam settings and online written exam settings, and developing effective procedure and policy to safeguard academic integrity during the COVID-19 pandemic that can help with facing various education and learning challenges in a time of crisis worldwide.

Given the limited access to medical facilities, impeding lockdown, and social isolation during the COVID-19 pandemic, an upsurge in postpartum depression among pregnant mothers in their puerperal period has become more apparent alongside an eventual increase in suicidal behavior. This article aimed to discuss the crucial aspects of different clinical case studies treated during recent periods throughout the COVID-19 pandemic via teleconsultations. We hoped to demonstrate tremendous opportunities for the application of healthcare via therapeutic tools online in telemedicine to manage such conditions in a developing country like Bangladesh with a severe scarcity of healthcare infrastructure and resources.

Digital formative assessments have the features of digital learning environment and can be used by teachers to both empower students’ learning and adapt the next steps in the learning process of their students. They are effective tools that can help lecturers and tutors to both collect and analyze the required information and data for supporting the teaching and learning processes. Importantly, digital formative assessments have been particularly critical during the COVID-19 pandemic due to increased students’ learning outside traditional classrooms, limited face-to-face classes and other students’ learning and assessment difficulties at many educational institutions worldwide. In this article, we describe the essential features and importance of digital formative assessments and their recently developed communication methods. We also discuss the significance of digital formative assessments in measuring students’ learning and skills in times of global crisis such as the COVID-19 pandemic.

<b>Background:</b> 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. <b>Methods:</b> 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. <b>Results:</b> 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. <b>Conclusions:</b> 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.

<b>Background:</b> Coronavirus disease has caused global turmoil especially causing huge impact on human life all over the world. Current reports states more than 3 million people have lost life and more than 160 million people are known to be suspected with the SARS-CoV-2. Transmission and disease incidence rates are indicators to assess the seriousness of COVID-19 pandemic and studies to understand the factors that aid in this direction are very vital to curb the disease. <b>Methods:</b> The study intends to discover the relationship by performing statistical analysis using correlation and multiple linear regression analysis between the variable’s population density, temperature, relative humidity, and active time of virus and find out the parameters that predict the cases reported per million population in 83 countries. <b>Results:</b> Analysis indicates active time of virus in days is very positively associated with the COVID -19 cases in all the countries <i>r </i>= .604, <i>p</i> < .01. Active time of virus shows strong negative correlation with temperature <i>r</i> = -.930, <i>p</i> < .01 revealing that rise in temperature will reduce the virus activity in the population. Together, these variables will account for 36.2% variance in the cases per million population with no significant prediction estimated from any factor. <b>Conclusion:</b> The study outcomes clearly state that population density alone is insufficient to estimate the extent of influence on COVID -19 cases as the number of persons living per sq. km of land is a dynamic quantity tend to fluctuate over time and space due to migration of population. In conjunction to the previous studies reported on the environmental and climatic factors influencing the cases reported, population dynamics does not show much significance on the disease spread and incidence.<b> Contribution:</b> The rise in confirmed cases and the high incidence rate reported in countries can be attributed to the active time of virus life expectancy as there is a positive correlation observed between the COVID-19 cases reported and the virus active time in the examined countries. Also, environment and climatic factors play a role in modulating the infection and transmission rate with less significant influence of population density on the COVID-19.

The economic and social effects that the COVID-19 pandemic and the associated measures to address it are having in Latin America may lead to serious long-term consequences that would affect the achievement of the Sustainable Development Goals. In this article, the collaboration of environmental economists from eight countries in the region discusses the possible effects of the pandemic on air pollution, deforestation, and other relevant environmental aspects related to the SDGs. In addition to presenting an account of some of the initial effects of the health crisis on the environment, the paper discusses potential effects in terms of environmental regulations and public policy interventions. Finally, the paper presents an agenda on new research topics that arise due to the pandemic or have gained greater importance due to it, including the impacts on the achievement of the Sustainable Development Goals. Briefly, this paper is a novel view of the sustainable development in Latin America and the Covid-19 impacts on this process.

COVID-19 demonstrated a global catastrophe that touched everybody, including the scientific community. As we respond and recover rapidly from this pandemic, there is an opportunity to guarantee that the fabric of our society includes sustainability, fairness, and care. However, approaches to environmental health attempt to decrease the populations burden of COVID-19, toward saving patients from becoming ill along with preserving the allocation of clinical resources and public safety standards. This paper explores environmental and public health evidence-based practices toward responding to Covid-19. A literature review tried to do a deep dive through the use of various search engines such as Mendeley, Research Gate, CAB Abstract, Google Scholar, Summon, PubMed, Scopus, Hinari, Dimension, OARE Abstract, SSRN, Academia search strategy toward retrieving research publications, “grey literature” as well as reports from expert working groups. To achieve enhanced population health, it is recommended to adopt widespread evidence-based strategies, particularly in this uncertain time. As only together can evidence-informed decision-making (EIDM) can become a reality which include effective policies and practices, transparency and accountability of decisions, and equity outcomes; these are all more relevant in resource-constrained contexts, such as Nigeria. Effective and ethical EIDM though requires the production as well as use of high-quality evidence that are timely, appropriate and structured. One way to do so is through co-production. Co-production (or co-creation or co-design) of environmental/public health evidence considered as a key tool for addressing complex global crises such as the high risk of severe COVID-19 in different nations. A significant evidence-based component of environmental/public health (EBEPH) consist of decisions making based on best accessible, evidence that is peer-reviewed; using data as well as systematic information systems; community engagement in policy making; conducting sound evaluation; do a thorough program-planning frameworks; as well as disseminating what is being learned. As researchers, scientists, statisticians, journal editors, practitioners, as well as decision makers strive to improve population health, having a natural tendency toward scrutinizing the scientific literature aimed at novel research findings serving as the foundation for intervention as well as prevention programs. The main inspiration behind conducting research ought to be toward stimulating and collaborating appropriately on public/environmental health action. Hence, there is need for a “Plan B” of effective behavioural, environmental, social as well as systems interventions (BESSI) toward reducing transmission.
