Drawing light from the pandemic: Rethinking strategies for health policy and beyond

Patterns of Mental Health and Resilience Among Nurses and Physicians Throughout the COVID-19 Pandemic: A 3-Year Longitudinal Study

OBJECTIVE

The COVID-19 pandemic is associated with increased difficulties in emotional well-being among healthcare workers. The current investigation assesses how changes in depression and anxiety symptoms fluctuate relative to resilience across three time points: baseline, 1-year, and 2-year follow-up among a cohort of physicians and nurses ( n = 728).

METHODS

Generalized linear mixed modeling for repeated-measures was used to assess the association between resilience and mental health symptoms using validated measures for all variables.

RESULTS

The odds of probable anxiety were reduced by 81% for each one-unit increase in resilience (odds ratio = 0.19, 95% confidence interval [0.14, 0.26]). The odds of probable depression were reduced by 88% for each one-unit increase in BRS (odds ratio = 0.12, 95% confidence interval [0.07, 0.2]).

CONCLUSIONS

Results highlight the importance of developing and implementing interventions that foster resilience among healthcare workers.

The attributes of public health leadership

The COVID-19 pandemic highlighted the importance of public health leadership. Yet, while there were many inspirational examples, too often, it was lacking. This personal perspective reflects on the experience of the pandemic, drawing on previous reflections on the role of public health professionals. It identifies eight key attributes that a public health leader should have. These are an ability to take the initiative, a sense of curiosity, a broad perspective on health threats, a recognition that there are those who are opposed to health, a willingness to speak truth to power, confidence, and the ability to engage with leaders in other sectors, a commitment to values, and an ability to communicate. In each case, it asks whether these attributes were apparent during the pandemic and why they might be needed in the future.

Nursing graduates' perceived future career pathway and career shift tendency in Egypt: a cross sectional study

PURPOSE

Addressing the dynamics shaping nurses' career trajectories and strategies to support workforce stability and retention in the healthcare sector. The aim of this study was to explore nursing graduates' perceptions of their future Career pathways, and their tendency toward career shifts. Additionally, the study examined the factors influencing career shift tendencies and the relation between career pathway perceptions and career shift tendencies.

METHODS

A descriptive cross-sectional study was used, with an online distributed questionnaire for study participants from different nursing graduates' categories. That included demographic characteristics, a section that measured nursing graduates' future career pathway perception, and career shift tendency.

RESULTS

Nursing graduates in Egypt were having a positive perception regarding their future career pathway. However, more than one quarter of them were considering career shift represents potential workforce instability and dissatisfaction within the nursing profession and financial factors was one of the main provoking drivers for career shift tendency. In addition, nursing graduates' perception of career pathway had a significant effect on their career shift tendency in future.

CONCLUSION

Based on the findings of this study, further efforts should be made to confront nursing shortage in Egypt, implementing targeted interventions to support nursing graduates in navigating their career pathways. Additionally, proactive measures should be taken to address the identified factors driving intentions to leave the profession, such as improving workplace conditions, fostering intergenerational collaboration, and offering mentorship programs. These strategies are essential for fostering a resilient and satisfied nursing workforce and ensuring the delivery of high-quality patient care in the healthcare sector.

An isothermal calorimetry assay for determining steady state kinetic and Ensitrelvir inhibition parameters for SARS-CoV-2 3CL-protease

This manuscript details the application of Isothermal Titration Calorimetry (ITC) to characterize the kinetics of 3CLpro, the main protease from the Severe Acute Respiratory Syndrome CoronaVirus-2 (SARS-CoV-2), and its inhibition by Ensitrelvir, a known non-covalent inhibitor. 3CLpro is essential for producing the proteins necessary for viral infection, which led to the COVID-19 pandemic. The ITC-based assay provided rapid and reliable measurements of 3CLpro activity, allowing for the direct derivation of the kinetic enzymatic constants KM and kcat by monitoring the thermal power required to maintain a constant temperature as the substrate is consumed. The manuscript highlights several advantages of the proposed ITC-based assay over traditional methods used to study 3CLpro, such as Förster Resonance Energy Transfer (FRET) and Liquid Chromatography-Mass Spectrometry (LC-MS) and overcomes the need for non-biological substrates or discontinuous post-reaction steps. The ease of application of the ITC method allowed for the determination of the temperature dependence of the catalytic constants, enabling the estimation of the reaction activation energy. Additionally, the assay was used to determine the inhibition mode and kinetic parameters for 3CLpro inhibition by Ensitrelvir. This molecule was revealed to act as a slow- and tight-binding inhibitor that forms an initial E•I complex (KI = 9.9 ± 0.7 nM) quickly transitioning to a tighter E•I* assembly (KI* = 1.1 ± 0.2 nM). This versatile calorimetric method is proposed for general use in the discovery and development of drugs targeting 3CLpro.

What makes health systems resilient? An analytical framework drawing on European learnings from the COVID-19 pandemic based on a multitiered approach

Introduction

The COVID-19 pandemic posed an unprecedented challenge, which caught many health systems widely unprepared. The aim of this research was to develop a comprehensive analytical framework on health system resilience in the context of pandemics. In addition to serving as a tool to analyse the preparedness and resilience of health systems, the framework is intended to provide guidance to decision-makers in health policy.

Methods

The analytical framework was developed based on a multitiered approach. A comprehensive review of the existing literature was conducted to identify relevant frameworks on health system resilience (published between 1 January 2000 and 30 November 2021) and determinants of resilience that emerged during the COVID-19 pandemic. Input was then gathered in several rounds of consultations with designated field experts and stakeholders, drawing on their experiences from the pandemic. Finally, the framework was empirically validated in several case studies.

Results

The framework distinguishes between prerequisites of resilience, pertaining to precautions to be taken in 'normal' times, and response strategies in the face of shocks. Both sections are further divided into six building blocks that were adapted from the WHO health system framework: governance and leadership, information and research, financing, physical resources, human resources, and service delivery. An overarching component on contextual factors-subdivided into situational, structural, cultural and international factors-represents an important addition to the existing spectrum of resilience frameworks.

Conclusions

Foundations for a resilient health system must be laid in 'normal' times and in all areas of the health system. In the face of a shock, adequate response strategies need to be developed. An essential learning from the COVID-19 pandemic has been that contextual factors of societies and subgroups play a major role in the ability of health systems to overcome a shock, as they impact the implementation and effectiveness of crisis management policies.

Prediction of viral spillover risk based on the mass action principle

Infectious zoonotic disease emergence, through spillover events, is of global concern and has the potential to cause significant harm to society, as recently demonstrated by COVID-19. More than 70% of the 400 infectious diseases that emerged in the past five decades have a zoonotic origin, including all recent pandemics. There have been several approaches used to predict the risk of spillover through some of the known or suspected infectious disease emergence drivers, largely using correlative approaches. Here, we predict the spatial distribution of spillover risk by approximating general transmission through animal and human interactions. These mass action interactions are approximated through the multiplication of the spatial distribution of zoonotic virus diversity and human population density. Although our results indicate higher risk in regions along the equator and in Southeast Asia where both virus diversity and human population density are high, it should be noted that this is primarily a conceptual exercise. We compared our spillover risk map to key factors, including the model inputs of zoonotic virus diversity estimate map, human population density map, and the spatial distribution of species richness. Despite the limitations of this approach, this viral spillover map is a step towards developing a more comprehensive spillover risk prediction system to inform global monitoring.

Health literacy, governance and systems leadership contribute to the implementation of the One Health approach: a virtuous circle

One Health is an important approach to addressing health threats and promoting health through interdisciplinary health, policy, legislation and leadership research to achieve better human and animal health and better outcomes for the planet. The Covid-19 pandemic has triggered an urgent awareness of the need to develop innovative integrative solutions to address root causes of such threats to health, which requires collaboration across disciplines and amongst different sectors and communities. We explore how achieving the Quadripartite Organizations' One Health Joint Plan of Action can be supported by the concepts of 'One Health literacy' and 'One Health governance' and promote both academic and policy dialogue. We show how One Health literacy and One Health governance influence and reinforce each other, while an interdisciplinary systems leadership approach acts as a catalyst and mechanism for understanding and enacting change. Based on our understanding of how these elements influence the implementation of the One Health approach, we describe a model for considering how external triggering events such as the Covid-19 pandemic may prompt a virtuous circle whereby exposure to and exploration of One Health issues may lead to improved One Health literacy and to better governance. We close with recommendations to international organisations, national governments and to leaders in policy, research and practice to enhance their influence on society, the planetary environment, health and well-being.

An isothermal calorimetry assay for determining steady state kinetic and enzyme inhibition parameters for SARS-CoV-2 3CL-protease

This manuscript describes the application of Isothermal Titration Calorimetry (ITC) to characterize the kinetics of 3CL pro from the Severe Acute Respiratory Syndrome CoronaVirus-2 (SARS-CoV-2) and its inhibition by Ensitrelvir, a known non-covalent inhibitor. 3CL pro is the main protease that plays a crucial role of producing the whole array of proteins necessary for the viral infection that caused the spread of COVID-19, responsible for millions of deaths worldwide as well as global economic and healthcare crises in recent years. The proposed calorimetric method proved to have several advantages over the two types of enzymatic assays so far applied to this system, namely Förster Resonance Energy Transfer (FRET) and Liquid Chromatography-Mass Spectrometry (LC-MS). The developed ITC-based assay provided a rapid response to 3CL pro activity, which was used to directly derive the kinetic enzymatic constants K M and k cat reliably and reproducibly, as well as their temperature dependence, from which the activation energy of the reaction was obtained for the first time. The assay further revealed the existence of two modes of inhibition of 3CL pro by Ensitrelvir, namely a competitive mode as previously inferred by crystallography as well as an unprecedented uncompetitive mode, further yielding the respective inhibition constants with high precision. The calorimetric method described in this paper is thus proposed to be generally and widely used in the discovery and development of drugs targeting 3CL pro .

The continuum of care as a unifying framework for intergenerational and interspecies health equity

Introduction

Unlocking the full potential of different people and organizations to address existential health threats requires shared goals and frameworks that allow people to see themselves contributing to a common and shared continuum of care. A new narrative to help people implement collective action for collective problems is needed.

Methods

This paper is draw from the co-authors experience working from the local to international level on planetary health problems.

Results

The proposed conceptual framework expands the socioecological model of health to help formulate multilevel approaches that foster healthier circumstances for all by revealing the mutual benefits that emerge from pooling expertise, funding, and political will to solve multiple problems with coordinated investment of resources and effort. It is intended to support program planning and communication. This framework is a response to the absence of systematic attempts to concurrently counteract the social and environmental conditions leading to disease, dysfunction and deficits which is increasingly seen as being problematic, especially as the root causes of health problems and solutions converge across species, sectors, and generations. The framework is embedded in the idea of interspecies and intergenerational health equity.

Discussion

Ensuring interspecies and intergenerational health equity requires each actor to fulfill their roles along the continuum while supporting the needs of others. A socio-ecological continuum of care provides bundled options that combine knowledge from different sectors, disciplines and perspectives to guide interventions over time across a comprehensive array of services and support spanning all levels of needs, species and generations.

Resilient health systems for already resilient countries? Pandemic discourses in the post-COVID-19 era

This study aimed to reconstruct and analyze the discourses of the pandemic in the post-COVID-19 era. The methodology was based on a critical review of the scientific literature on the pandemic, selecting 80 non-biomedical, clinical, or pharmacological articles published in journals indexed in Scopus or Web of Science from a sample of the 500 most cited scientific articles on the pandemic in Google Scholar. The theoretical approach was based on the debates on predictability, unpredictability, determination, and indeterminacy in the health and social sciences. As a result, six theses on the pandemic were identified and analyzed: a) the thesis of the unpredictability of pandemics; b) the thesis of pandemic denial; c) the thesis of the pandemic as a failure in predictability systems; d) the thesis of the prevention of catastrophic events with timely interventions; e) the thesis of the structural postponement of predictive care by non-developed countries; and f) the environmentalist-health thesis, of foreseeing a critical phase for the planet and humanity. We concluded on the limits of resilience as the center in preparing Latin American health systems in the post-pandemic.

The launch of the EU Health Emergency Preparedness and Response Authority (HERA): Improving global pandemic preparedness?

The crowded global health landscape has been joined by the European Union Health Emergency Preparedness and Response Authority (HERA). HERA will assume four broad areas of responsibility: horizon scanning for major health threats; research and development; support for capacity to manufacture drugs, vaccines, and equipment; and procuring and stockpiling key medical countermeasures. In this Health Reform Monitor article, we outline the reform process and describe HERA's structure and responsibilities, explore issues that arise from the creation of this new organisation, and suggest options for collaboration with existing bodies in Europe and beyond. The COVID-19 pandemic and other infectious disease outbreaks have shown the need to treat health as a cross-border issue, and there is now a broad consensus that greater direction and coordination at the European level is needed. This ambition has been matched with a considerable increase in EU funding to tackle cross-border health threats, and HERA can be used to deploy this funding in an effective manner. Yet this is contingent upon clearly defining its role and responsibilities vis-à-vis existing agencies to reduce redundancies.

Divergent COVID-19 vaccine policies: policy mapping of ten European countries

Background

The COVID-19 pandemic highlighted the fragmented nature of governmental policy decisions in Europe. However, the extent to which COVID-19 vaccination policies differed in various European countries remains unclear. Here, we mapped the COVID-19 vaccination policies that were in force in January 2022 as well as booster regulations as of April 2022 in Austria, Denmark, England, France, Germany, Ireland, Italy, the Netherlands, Poland, and Spain.

Methods

National public health and health policy experts from these ten European nations developed and completed an electronic questionnaire. The questionnaire included a series of questions that addressed six critical components of vaccine implementation, including (1) authorization, (2) prioritization, (3) procurement and distribution, (4) data collection, (5) administration, and (6) mandate requirements.

Results

Our findings revealed significant variations in COVID-19 vaccination policies across Europe. We observed critical differences in COVID-19 vaccine formulations that were authorized for use as well as the specific groups that were provided with priority access. We also identified discrepancies in how vaccination-related data were recorded in each country and what vaccination requirements were implemented.

Conclusion

Each of the ten European nations surveyed in this study reported different COVID-19 vaccination policies. These differences complicated efforts to provide a coordinated pandemic response. These findings might alert policymakers in Europe of the need to coordinate their efforts to avoid fostering divergent and socially disruptive policies.

Health systems resilience: is it time to revisit resilience after COVID-19?

The concept of health system resilience has been challenged by the COVID-19 pandemic. Even well-established health systems, considered resilient, collapsed during the pandemic. To revisit the concept of resilience two years and a half after the initial impact of COVID-19, we conducted a qualitative study with 26 international experts in health systems to explore their views on concepts, stages, analytical frameworks, and implementation from a comparative perspective of high- and low-and-middle-income countries (HICs and LMICs). The interview guide was informed by a comprehensive literature review, and all interviewees had practice and academic expertise in some of the largest health systems in the world. Results show that the pandemic did modify experts' views on various aspects of health system resilience, which we summarize and propose as refinements to the current understanding of health systems resilience.

SDG5 "Gender Equality" and the COVID-19 pandemic: A rapid assessment of health system responses in selected upper-middle and high-income countries

Introduction

The COVID-19 pandemic disrupted healthcare and societies, exacerbating existing inequalities for women and girls across every sphere. Our study explores health system responses to gender equality goals during the COVID-19 pandemic and inclusion in future policies.

Methods

We apply a qualitative comparative approach, drawing on secondary sources and expert information; the data was collected from March-July 2022. Australia, Brazil, Germany, the United Kingdom, and the USA were selected, reflecting upper-middle and high-income countries with established public health and gender policies but different types of healthcare systems and epidemiological and geo-political conditions. Three sub-goals of SDG5 were analyzed: maternity care/reproductive health, gender-based violence, and gender equality/women's leadership.

Results

We found similar trends across countries. Pandemic policies strongly cut into women's health, constrained prevention and support services, and weakened reproductive rights, while essential maternity care services were kept open. Intersecting gender inequalities were reinforced, sexual violence increased and women's leadership was weak. All healthcare systems failed to protect women's health and essential public health targets. Yet there were relevant differences in the responses to increased violence and reproductive rights, ranging from some support measures in Australia to an abortion ban in the US.

Conclusions

Our study highlights a need for revising pandemic policies through a feminist lens.

[Changes in sleep patterns and the doom-scrolling (doom-surfing) phenomenon as modifiable risk factors for anxiety due to continuous stress of the COVID-19 pandemic]

OBJECTIVE

To evaluate the modifiable daily behavior patterns associated with increased anxiety indicators in the general population in response to the COVID-19 pandemic.

MATERIAL AND METHODS

The study examined the characteristics of the Russian population (n=7777) of the international multicenter project COMET-G. In particular, variables were targeted to describe deviations in the behavior of adults during the period of application of measures of social isolation in connection with the pandemic, and revealing a relationship with the total score on the Spielberger State Anxiety Scale (STAI-S). Among these variables, experts selected those that could potentially be subject to change in the short term, that is, act as manageable or modifiable risk factors for the development of anxiety. The selected variables were analyzed in a statistical PLS-model to identify indicators that make the most significant contribution to the increase in the total anxiety score.

RESULTS

Our statistical model explained 48.4% of the variability in the STAI-S anxiety total scores related to changes in daily life habits. In particular, doom-scrolling/doom-surfing about the spread of the virus and the COVID-19 pandemic, changes in sleep patterns and usual daily life activities due to social isolation measures presented as factors significantly contributing to the increase of state anxiety.

CONCLUSION

Given the manageable or modifiable risk factors that we have identified, public awareness and therapeutic recommendations, pointing to the need to (I) control the amount of time spent in the internet and monitor their internet-based content consumption, (II) regulate sleep-wake patterns, (III) maintain daily habits and household activities, may reduce the likelihood of developing anxiety disorders in the context of the impact of a global chronic stress due to the COVID-19 pandemic and associated social isolation measures.

The impact of the COVID-19 pandemic on diabetes services: planning for a global recovery

The COVID-19 pandemic has disproportionately affected certain groups, such as older people (ie, >65 years), minority ethnic populations, and people with specific chronic conditions including diabetes, cardiovascular disease, kidney disease, and some respiratory diseases. There is now evidence of not only direct but also indirect adverse effects of COVID-19 in people with diabetes. Recurrent lockdowns and public health measures throughout the pandemic have restricted access to routine diabetes care, limiting new diagnoses, and affecting self-management, routine follow-ups, and access to medications, as well as affecting lifestyle behaviours and emotional wellbeing globally. Pre-pandemic studies have shown that short-term delays in delivery of routine care, even by 12 months, are associated with adverse effects on risk factor control and worse microvascular, macrovascular, and mortality outcomes in people with diabetes. Disruptions within the short-to-medium term due to natural disasters also result in worse diabetes outcomes. However, the true magnitude of the indirect effects of the COVID-19 pandemic on long-term outcomes and mortality in people with diabetes is still unclear. Disasters tend to exacerbate existing health disparities; as we recover ambulatory diabetes services in the aftermath of the pandemic, there is an opportunity to prioritise those with the greatest need, and to target resources and interventions aimed at improving outcomes and reducing inequality.

Structure and inhibition of SARS-CoV-1 and SARS-CoV-2 main proteases by oral antiviral compound AG7404

Severe acute respiratory syndrome coronaviruses 1 and 2 (SARS-CoV-1 and SARS-CoV-2) pose a threat to global public health. The 3C-like main protease (M^pro), which presents structural similarity with the active site domain of enterovirus 3C protease, is one of the best-characterized drug targets of these viruses. Here we studied the antiviral activity of the orally bioavailable enterovirus protease inhibitor AG7404 against SARS-CoV-1 and SARS-CoV-2 from a structural, biochemical, and cellular perspective, comparing it with the related molecule rupintrivir (AG7800). Crystallographic structures of AG7404 in complex with SARS-CoV-1 M^pro and SARS-CoV-2 M^pro and of rupintrivir in complex with SARS-CoV-2 M^pro were solved, revealing that all protein residues interacting with the inhibitors are conserved between the two proteins. A detailed analysis of protein-inhibitor interactions indicates that AG7404 has a better fit to the active site of the target protease than rupintrivir. This observation was further confirmed by biochemical FRET assays showing IC₅₀ values of 47 μM and 101 μM for AG7404 and rupintrivir, respectively, in the case of SARS-CoV-2 M^pro. Equivalent IC₅₀ values for SARS-CoV-1 also revealed greater inhibitory capacity of AG7404, with a value of 29 μM vs. 66 μM for rupintrivir. Finally, the antiviral activity of the two inhibitors against SARS-CoV-2 was confirmed in a human cell culture model of SARS-CoV-2 infection, although rupintrivir showed a higher potency and selectivity index in this assay.

It was good while it lasted: politics is at the heart of public health but are we willing to engage?

This paper, written to mark the 50th anniversary of the Faculty of Public Health, reflects on the challenges to governance in a United Kingdom outside the European Union. Drawing on Virchow's call to address the political determinants of health, it describes a situation in which the current government consistently displays disregard for the institutions of state, and the principles on which they are based, such as honesty and the rule of law. It argues that this is a departure from the past and that it undermines the trust that is essential for effective public health policies that attract public support. It ends with a challenge to the public health establishment in the United Kingdom to decide whether they will challenge the decline in public standards, and thus promote structures that can consider and prioritize health or continue to pick up the pieces of political failings.

Healthcare Workers' Perceptions and Medically Approved COVID-19 Infection Risk: Understanding the Mental Health Dimension of the Pandemic. A German Hospital Case Study

Introduction

This study analyses how healthcare workers (HCWs) perceived risks, protection and preventive measures during the COVID-19 pandemic in relation to medically approved risks and organizational measures. The aim is to explore “blind spots” of pandemic protection and make mental health needs of HCWs visible.

Methods

We have chosen an “optimal-case” scenario of a high-income country with a well-resourced hospital sector and low HCW infection rate at the organizational level to explore governance gaps in HCW protection. A German multi-method hospital study at Hannover Medical School served as empirical case; document analysis, expert information and survey data (n = 1,163) were collected as part of a clinical study into SARS-CoV-2 serology testing during the second wave of the pandemic (November 2020-February 2021). Selected survey items included perceptions of risks, protection and preventive measures. Descriptive statistical analysis and regression were undertaken for gender, profession and COVID-19 patient care.

Results

The results reveal a low risk of 1% medically approved infections among participants, but a much higher mean personal risk estimate of 15%. The majority (68.4%) expressed “some” to “very strong” fear of acquiring infection at the workplace. Individual protective behavior and compliance with protective workplace measures were estimated as very high. Yet only about half of the respondents felt strongly protected by the employer; 12% even perceived “no” or “little” protection. Gender and contact with COVID-19 patients had no significant effect on the estimations of infection risks and protective workplace behavior, but nursing was correlated with higher levels of personal risk estimations and fear of infection.

Conclusions

A strong mismatch between low medically approved risk and personal risk perceptions of HCWs brings stressors and threats into view, that may be preventable through better information, training/education and risk communication and through investment in mental health and inclusion in pandemic preparedness plans.

Antiviral Activities of High Energy E-Beam Induced Copper Nanoparticles against H1N1 Influenza Virus

The pandemic outbreak of COVID-19 in the year of 2020 that drastically changed everyone's life has raised the urgent and intense need for the development of more efficacious antiviral material. This study was designed to develop copper nanoparticles (Cu NPs) as an antiviral agent and to validate the antiviral activities of developed copper NP. The Cu NPs were synthesized using a high energy electron beam, and the characteristic morphologies and antiviral activities of Cu NPs were evaluated. We found that Cu NPs are of spherical shape and uniformly distributed, with a diameter of around 100 nm, as opposed to the irregular shape of commercially available copper microparticles (Cu MPs). An X-ray diffraction analysis showed the presence of Cu and no copper oxide II and I in the Cu NPs. A virus inactivation assay revealed no visible viral DNA after 10- and 30-min treatment of H1N1 virus with the Cu NPs. The infectivity of the Cu NPs-treated H1N1 virus significantly decreased compared with that of the Cu MPs-treated H1N1 virus. The viability of A549 bronchial and Madin-Darby Canine Kidney (MDCK) cells infected with Cu NPs-treated H1N1 was significantly higher than those infected with Cu MPs-treated H1N1 virus. We also found cells infected with Cu NPs-treated H1N1 virus exhibited a markedly decreased presence of virus nucleoprotein (NuP), an influenza virus-specific structural protein, compared with cells infected with Cu MPs-treated H1N1 virus. Taken together, our study shows that Cu NPs are a more effective and efficacious antiviral agent compared with Cu MPs and offer promising opportunities for the prevention of devastatingly infectious diseases.
