A Call to Action for Gender Equity in Climate Leadership.

Climate action is not advancing quickly enough to prevent catastrophic harm. Understanding why might require looking at existing leadership structures and the inequitable gender representation therein. Critically examining dominant power structures could pave the way toward more comprehensive, innovative, and expedient environmental solutions-and we argue that elevating women's climate leadership is key to safeguarding planetary health. Women have historically been left out of climate science and governance leadership. Women are disproportionately impacted by the health effects of climate change, particularly in Indigenous and low- and middle-income settings. Therefore, our call for women's climate leadership is both an issue of justice and a matter of effectiveness, given evidence that inclusive leadership rooted in gender justice leads to more equitable outcomes. Here, we present evidence for why gender equity in climate leadership matters along with considerations for how to attain it across sectors and stakeholders.

What We Lost in the Fire: Endemic Tropical Heart Diseases in the Time of COVID-19.

The COVID-19 pandemic has profoundly influenced the effort to achieve global health equity. This has been particularly the case for HIV/AIDS, tuberculosis, and malaria control initiatives in low- and middle-income countries, with significant outcome setbacks seen for the first time in decades. Lost in the calls for compensatory funding increases for such programs, however, is the plight of endemic tropical heart diseases, a group of disorders that includes rheumatic heart disease, Chagas disease, and endomyocardial fibrosis. Such endemic illnesses affect millions of people around the globe and remain a source of substantial mortality, morbidity, and health disparity. Unfortunately, these conditions were already neglected before the pandemic, and thus those living with them have disproportionately suffered during the time of COVID-19. In this perspective, we briefly define endemic tropical heart diseases, summarizing their prepandemic epidemiology, funding, and control statuses. We then describe the ways in which people living with these disorders, along with the healthcare providers and researchers working to improve their outcomes, have been harmed by the ongoing COVID-19 pandemic. We conclude by proposing the path forward, including approaches we may use to leverage lessons learned from the pandemic to strengthen care systems for these neglected diseases.

Ecological and socioeconomic factors associated with the human burden of environmentally mediated pathogens: a global analysis.

BACKGROUND: Billions of people living in poverty are at risk of environmentally mediated infectious diseases-that is, pathogens with environmental reservoirs that affect disease persistence and control and where environmental control of pathogens can reduce human risk. The complex ecology of these diseases creates a global health problem not easily solved with medical treatment alone. METHODS: We quantified the current global disease burden caused by environmentally mediated infectious diseases and used a structural equation model to explore environmental and socioeconomic factors associated with the human burden of environmentally mediated pathogens across all countries. FINDINGS: We found that around 80% (455 of 560) of WHO-tracked pathogen species known to infect humans are environmentally mediated, causing about 40% (129 488 of 359 341 disability-adjusted life years) of contemporary infectious disease burden (global loss of 130 million years of healthy life annually). The majority of this environmentally mediated disease burden occurs in tropical countries, and the poorest countries carry the highest burdens across all latitudes. We found weak associations between disease burden and biodiversity or agricultural land use at the global scale. In contrast, the proportion of people with rural poor livelihoods in a country was a strong proximate indicator of environmentally mediated infectious disease burden. Political stability and wealth were associated with improved sanitation, better health care, and lower proportions of rural poverty, indirectly resulting in lower burdens of environmentally mediated infections. Rarely, environmentally mediated pathogens can evolve into global pandemics (eg, HIV, COVID-19) affecting even the wealthiest communities. INTERPRETATION: The high and uneven burden of environmentally mediated infections highlights the need for innovative social and ecological interventions to complement biomedical advances in the pursuit of global health and sustainability goals.

Characterization and regulation of microplastic pollution for protecting planetary and human health.

Microplastics are plastic particles <5 mm in diameter. Since the 1950s, there has been an exponential increase in the production of plastics. As of 2015, it is estimated that approximately 6300 million metric tons of plastic waste had been generated of which 79% has accumulated in landfills or the natural environment. Further, it is estimated that if current trends continue, roughly 12,000 million metric tons of plastic waste will accumulate by 2050. Plastics and microplastics are now found ubiquitously-in the air, water, and soil. Microplastics are small enough to enter the tissues of plants and animals and have been detected in human lungs, stools, placentas, and blood. Their presence in human tissues and the food chain is a cause for concern. While direct clinical evidence or epidemiological studies on the adverse effects of microplastic on human health are lacking, in vitro cellular and tissue studies and in vivo animal studies suggest potential adverse effects. With the ever-increasing presence of plastic waste in our environment, it is critical to understand their effects on our environment and on human health. The use of plastic additives, many of which have known toxic effects are also of concern. This review provides a brief overview of microplastics and the extent of the microplastic problem. There have been a few inroads in regulating plastics but currently these are insufficient to adequately mitigate plastic pollution. We also review recent advances in microplastic testing methodologies, which should support management and regulation of plastic wastes. Significant efforts to reduce, reuse, and recycle plastics are needed at the individual, community, national, and international levels to meet the challenge. In particular, significant reductions in plastic production must occur to curb the impacts of plastic on human and worldwide health, given the fact that plastic is not truly recyclable.

An Online Ethics Curriculum for Short-Term Global Health Experiences: Evaluating a Decade of Use.

Background: Medical students and early career healthcare professionals commonly participate in short-term experiences in global health (STEGH). Objective: The authors evaluate the use of a free-to-access, case-based online curriculum addressing ethical issues trainees should consider prior to engaging in STEGH. Methods: Demographic data and feedback on specific cases were collected from 5,226 respondents accessing the online curriculum between November 1, 2011 and October 31, 2021. Feedback on the curriculum included 5-point Likert scale and open-ended responses. Quantitative data were analyzed using standard descriptive statistics. Qualitative data were independently dual coded and analyzed thematically in NVivo. Findings: The curriculum reached respondents from 106 countries. Undergraduate (36%) and graduate (38%) respondents included those from several different professional specialties. Less than a quarter of all of respondents, less than half with previous global health experience, and one-third with planned future global health experiences had received prior global health ethics training. Overall, the curriculum was highly rated; respondents felt it provided necessary tools to improve their thought processes, confidence, and behavior when encountering ethical issues during STEGH. Areas for curriculum improvement include balancing case specificity with generalizability. Conclusion: This curriculum has met a need for accessible introductory global health ethics education and demonstrates successful use of an online platform in case-based ethics learning.

What Do Global Health Practitioners Think about Decolonizing Global Health?

The growing awareness of colonialism's role in global health partnerships between HICs and LMICs and the associated calls for decolonization in global health has led to discussion for a paradigm shift that would lead to new ways of engagement and partnerships, as well as an acknowledgement that colonialism, racism, sexism, and capitalism contribute to inequity. While there is general agreement among those involved in global health partnerships that the current system needs to be made more equitable, suggestions for how to address the issue of decolonization vary greatly, and moving from rhetoric to reform is complicated. Based on a comprehensive (but not exhaustive) review of the literature, there are several recurring themes that should be addressed in order for the inequities in the current system to be changed. The degree to which decolonization of global health will be successful depends on how the global health community in both the HICs and LMICs move forward to discuss these issues. Specifically, as part of a paradigm shift, attention needs to be paid to creating a more equal and equitable representation of researchers in LMICs in decision-making, leadership roles, authorship, and funding allocations. There needs to be agreement in defining basic principles of best practices for global partnership, including a universal definition of 'decolonization of global health'; the extent to which current policies allow the perpetuation of power imbalance between HICs and LMICs; a set of principles, best practices, and models for equitable sharing of funds and institutional costs among partners; a mechanism to monitor progress prospectively the equitable sharing of credits (e.g., leadership, authorship), including a set of principles, best practices, and models; and, a mechanism to monitor progress prospectively the extent to which decolonialization will contribute to strengthening institutional capacity in the LMIC institutions.

Experiences of United States Graduates at the Latin American Medical School in Cuba: A Road Less Traveled.

OBJECTIVES: Determine if United States graduates of the Latin American Medical School in Cuba: 1) provide primary health care to disadvantaged populations; 2) complete licensing exams and obtain residencies; and 3) accrue additional debt during their medical education. METHODS: A Qualtrics secure web-based survey was provided to 158 graduates via email, completed anonymously. Responses were compiled and descriptive statistics generated. RESULTS: Fifty-six valid surveys were returned, for a response rate of 35.4%. Chi-square analysis showed no statistically significant differences between survey respondents and the sampling frame. Most graduates are people of color; 68% work in clinical medicine; of these, 90% are in primary care, with 100% serving disadvantaged populations. Most accrued no further educational loan debt. CONCLUSIONS: United States graduates of the Latin American Medical School work in primary care with disadvantaged populations. Graduates accrue little additional student loan debt.

The Stanford Global Health Media Fellowship: Training the Next Generation of Physician Communicators to Fight Health Misinformation.

PROBLEM: The COVID-19 pandemic and the spread of related health misinformation, especially on social media, have highlighted the need for more health care professionals to produce and share accurate health information to improve health and health literacy. Yet, few programs address this problem by training health care professionals in the art of science writing and medical journalism. APPROACH: Created in 2011, the Stanford Global Health Media Fellowship aims to train medical students and residents in public communication strategies. Each year, 1 physician-in-training is selected to complete the fellowship, which includes 3 rotations: (1) 1 academic quarter at Stanford's Graduate Program in Journalism, (2) 3 to 5 months with a national news network (previously NBC and ABC, now CNN), and (3) a placement at an international site. During the year-long program, fellows also complete a capstone project tackling a global health equity issue. OUTCOMES: Since 2011, 10 fellows have completed the program, and they have acquired skills in reporting, writing, multimedia, social media, and medical communications. During the news network rotation, they have completed more than 200 medical news pieces and improved the quality of the health information in a myriad of other pieces. Alumni have continued to write and report on medical stories throughout residency, other fellowships, and as practicing physicians. One alumnus is now a medical news producer at CNN. NEXT STEPS: Expanding high-quality training in medical journalism for physicians through partnerships with journalism schools; communications departments; and local, national, and international journalists can greatly improve physicians' ability to communicate with the public. It also has the potential to greatly improve the health information the public receives. Educators should consider embedding mass health communications training in medical education curricula and increasing opportunities for physicians to engage with diverse public audiences.

Climate change and global health: A call to more research and more action.

There is increasing understanding, globally, that climate change and increased pollution will have a profound and mostly harmful effect on human health. This review brings together international experts to describe both the direct (such as heat waves) and indirect (such as vector-borne disease incidence) health impacts of climate change. These impacts vary depending on vulnerability (i.e., existing diseases) and the international, economic, political, and environmental context. This unique review also expands on these issues to address a third category of potential longer-term impacts on global health: famine, population dislocation, and environmental justice and education. This scholarly resource explores these issues fully, linking them to global health in urban and rural settings in developed and developing countries. The review finishes with a practical discussion of action that health professionals around the world in our field can yet take.

Clinical Outcomes, Echocardiographic Findings, and Care Quality Metrics for People Living With Human Immunodeficiency Virus (HIV) and Rheumatic Heart Disease in Uganda.

BACKGROUND: Rheumatic heart disease (RHD) affects 41 million people worldwide, mostly in low- and middle-income countries, where it is co-endemic with human immunodeficiency virus (HIV). HIV is also a chronic inflammatory disorder associated with cardiovascular complications, yet the epidemiology of patients affected by both diseases is poorly understood. METHODS: Utilizing the Uganda National RHD Registry, we described the echocardiographic findings, clinical characteristics, medication prescription rates, and outcomes of all 73 people carrying concurrent diagnoses of HIV and RHD between 2009 and 2018. These individuals were compared to an age- and sex-matched cohort of 365 subjects with RHD only. RESULTS: The median age of the HIV-RHD group was 36 years (interquartile range [IQR] 15), and 86% were women. The HIV-RHD cohort had higher rates of prior stroke/transient ischemic attack (12% vs 5%, P = .02) than the RHD-only group, with this association persisting following multivariable adjustment (odds ratio [OR] 3.08, P = .03). Prevalence of other comorbidities, echocardiographic findings, prophylactic penicillin prescription rates, retention in clinical care, and mortality were similar between the 2 groups. CONCLUSIONS: Patients living with RHD and HIV in Uganda are a relatively young, predominantly female group. Although RHD-HIV comorbid individuals have higher rates of stroke, their similar all-cause mortality and RHD care quality metrics (such as retention in care) compared to those with RHD alone suggest rheumatic heart disease defines their clinical outcome more than HIV does. We believe this study to be one of the first reports of the epidemiologic profile and longitudinal outcomes of patients who carry diagnoses of both conditions.

Virtual Exchange in Global Health: an innovative educational approach to foster socially responsible overseas collaboration.

Educators who design and manage study abroad programs face a series of ethical responsibilities. Meeting these responsibilities is critical in the field of global health, where study abroad programs are often designed to provide healthcare services in under-resourced communities. Leaders in global health have thus formed working groups to study the ethical implications of overseas programming and have led the way in establishing socially responsible best practices for study abroad. Their recommendations include development of bidirectional programming that is designed for mutual and equitable benefits, focused on locally identified needs and priorities, attentive to local community costs, and structured to build local capacity to ensure sustainability. Implementation remains a key challenge, however. Sustainable, bidirectional programming is difficult and costly. In the present study, authors questioned how technology could be used to connect students of global health in distant countries to make socially responsible global health programming more accessible. Drawing on empirical research in the learning sciences and leveraging best practices in technology design, the authors developed a Virtual Exchange in Global Health to connect university students in the U.S. with counterparts in Lebanon, who worked in teams to address humanitarian problems in Syrian refugee camps. Early results demonstrate the value of this approach. At dramatically lower cost than traditional study abroad-and with essentially no carbon footprint-students recognized complementary strengths in each other through bidirectional programming, learned about local needs and priorities through Virtual Reality, and built sustaining relationships while addressing a difficult real-world problem. The authors learned that technology could effectively facilitate socially responsible global health programming and do so at low cost. The program has important implications for teaching and learning during the COVID-19 crisis and beyond.

Health system and patient-level factors serving as facilitators and barriers to rheumatic heart disease care in Sudan.

BACKGROUND: Rheumatic heart disease (RHD) remains a leading cause of morbidity and mortality in Sub-Saharan Africa despite widely available preventive therapies such as prophylactic benzathine penicillin G (BPG). In this study, we sought to characterize facilitators and barriers to optimal RHD treatment with BPG in Sudan. METHODS: We conducted a mixed-methods study, collecting survey data from 397 patients who were enrolled in a national RHD registry between July and November 2017. The cross-sectional surveys included information on demographics, healthcare access, and patient perspectives on treatment barriers and facilitators. Factors associated with increased likelihood of RHD treatment adherence to prophylactic BPG were assessed by using adjusted logistic regression. These data were enhanced by focus group discussions with 20 participants, to further explore health system factors impacting RHD care. RESULTS: Our quantitative analysis revealed that only 32% of the study cohort reported optimal prophylaxis adherence. Younger age, reduced primary RHD healthcare facility wait time, perception of adequate health facility staffing, increased treatment costs, and high patient knowledge about RHD were significantly associated with increased odds of treatment adherence. Qualitative data revealed significant barriers to RHD treatment arising from health services factors at the health system level, including lack of access due to inadequate healthcare staffing, lack of faith in local healthcare systems, poor ancillary services, and patient lack of understanding of disease. Facilitators of RHD treatment included strong interpersonal support. CONCLUSIONS: Multiple patient and system-level barriers to RHD prophylaxis adherence were identified in Khartoum, Sudan. These included patient self-efficacy and participant perception of healthcare facility quality. Strengthening local health system infrastructure, while enhancing RHD patient education, may help to improve treatment adherence in this vulnerable population.

Protocol for a feasibility randomized trial of self-management support for people with chronic obstructive pulmonary disease using lay health coaches.

Challenges with self-management are a major contributor to poor outcomes among adults with chronic obstructive pulmonary disease (COPD). The causes of poor self-management in COPD are manifold, and they arise from physical, cognitive, socioeconomic, environmental and societal sources. To address this complexity, we developed the Supporting self-Management Behaviors in Adults with COPD (SaMBA-COPD) model, which uses lay health coaches to identify a patient's barriers to effective COPD self-management and provide tailored support to help them overcome those barriers, reduce their symptoms and need for urgent care and improve their quality of life. The 6-month intervention includes referral of patients to a pharmacist for prescription of antibiotic and oral steroid "rescue packs" and support for a structured home exercise routine. All interactions of coaches and patients will take place by telephone or video call. We will test the feasibility and preliminary efficacy of SaMBA-COPD in a trial of 58 patients randomized 1:1 to the intervention or a COPD education control. Outcomes will be assessed at 6 and 9 months. Data from the trial will be used to inform the design of a fully powered, multi-site randomized trial of the intervention.

Global health security as it pertains to Zika, Ebola, and COVID-19.

PURPOSE OF REVIEW: Due to the impact of the COVID-19 pandemic this past year, we have witnessed a significant acceleration in the science, technology, and policy of global health security. This review highlights important progress made toward the mitigation of Zika, Ebola, and COVID-19 outbreaks. These epidemics and their shared features suggest a unified policy and technology agenda that could broadly improve global health security. RECENT FINDINGS: Molecular epidemiology is not yet in widespread use, but shows promise toward informing on-the-ground decision-making during outbreaks. Point-of-care (POC) diagnostics have been achieved for each of these threats; however, deployment of Zika and Ebola diagnostics lags behind those for COVID-19. POC metagenomics offers the possibility of identifying novel viruses. Vaccines have been successfully approved for Ebola and COVID-19, due in large part to public-private partnerships and advance purchase commitments. Therapeutics trials conducted during ongoing epidemics have identified effective antibody therapeutics for Ebola, as well as steroids (both inhaled and oral) and a broad-spectrum antiviral for COVID-19. SUMMARY: Achieving global health security remains a challenge, though headway has been made over the past years. Promising policy and technology strategies that would increase resilience across emerging viral pathogens should be pursued.

More Women Must Lead in Global Health: A Focus on Strategies to Empower Women Leaders and Advance Gender Equality.

Despite comprising 70% of the health workforce, women fill only 25% of senior and 5% of top health organization positions. Greater diversity in global health leadership, particularly greater representation of women, is essential to ensure diverse perspectives and ideas inform policies and priorities. Interviews and literature reviews surfaced many of the key challenges that women in global health face at individual, organizational and societal levels. Initiatives working to advance women's leadership are encouraged to consider 5 key priorities that address these challenges.
