Crise global da atenção primária à saúde / Global crisis in primary health care / Crisis global de la atención primaria

Enquanto no Norte Global se discute uma crise na Atenção Primária à Saúde, a maioria dos países nunca chegou a constituir sistemas de saúde baseados propriamente numa atenção primária robusta. Nesse cenário, o Brasil apresenta uma tendência mais favorável, com conquistas importantes para a atenção primária e a medicina de família e comunidade nos últimos dez anos. Restam desafios a serem superados para que o Sistema Único de Saúde alcance níveis satisfatórios de acesso a seus serviços, com profissionais adequadamente formados e valorizados pela população.

While the Global North is discussing a crisis in primary health care, the majority of countries have never managed to establish health systems based on robust primary care. Brazil presents a more favorable trend, with important achievements for primary care and family practice over the last ten years. There are still challenges to be overcome so that the Unified Health System achieves satisfactory levels of access to its services, with professionals who are properly trained and valued by the public.

Mientras que en el Norte Global se habla de una crisis de la atención primaria, la mayoría de los países nunca han creado realmente sistemas sanitarios basados en una atención primaria robusta. Brasil, muestra una tendencia más favorable, con importantes logros para la atención primaria y la medicina familiar y comunitaria en los últimos diez años. Aún quedan retos por superar para que el Sistema Único de Salud alcance niveles satisfactorios de acceso a sus servicios, con profesionales debidamente formados y valorados por la población.

Vulnerability, social value and the equitable sharing of benefits from research: beyond the placebo and access debates.

The vulnerability of research participants is a critical topic for the 2024 revision of the Declaration of Helsinki, with the proposal to include "social value. " However, this proposal has been withdrawn and the relationship between the two concepts has not been clarified. This paper attempts to clarify: (1) the recent reform for the ethical inclusion of vulnerable study participants to promote diversity; (2) the social value, prerequisite for everyone, especially for those who are vulnerable and the most in need; (3) the requirements for promoting the inclusion of vulnerable participants, in particular the review of the norms for placebo-controlled trials and post-trial access; (4) finally, the direction of research ethics reform to achieve social value and equitable global health.

Advancing governance for digital transformation in health: insights from Georgia's experience.

Enhancing digital health governance is critical to healthcare systems in low-income and middle-income countries. However, implementing governance-enhancing reforms in these countries is often challenging due to the multiplicity of external players and insufficient operational guidance that is accessible. Using data from desktop research, in-depth interviews, focus group discussions and three stakeholder workshops, this paper aims to provide insights into Georgia's experience in advancing digital health governance reforms. It reveals how Georgia has progressed on this path by unpacking the general term 'governance' into operational domains, where stakeholders and involved institutions could easily relate their institutional and personal roles and responsibilities with the specific function needed for digital health. Based on this work, the country delineated institutional responsibilities and passed the necessary regulations to establish better governance arrangements for digital health. The Georgia experience provides practical insights into the challenges faced and solutions found for advancing digital health governance in a middle-income country setting. The paper highlights the usefulness of operational definitions for the digital health governance domains that helped (a) increase awareness among stakeholders about the identified domains and their meaning, (b) discuss possible governance and institutional arrangements relevant to a country context, and (c) design the digital health governance architecture that the government decreed. Finally, the paper offers a broad description of domains in which the governance arrangements could be considered and used for other settings where relevant. The paper points to the need for a comprehensive taxonomy for governance domains to better guide digital health governance enhancements in low-middle-income country settings.

Skin diseases among adults in Tasiilaq, East Greenland.

Cold climate and unique genetic and environmental factors may influence the prevalence of skin diseases in Greenland. However, there is a lack of epidemiological studies on skin diseases in the adult Greenlandic population. To address this unmet need a cross-sectional study, run by dermatologists from Denmark, the UK, and Switzerland estimated the prevalence and clinical manifestations of skin diseases among adults in East Greenland in May 2022. All adults ≥18 years in the town of Tasiilaq were invited, and 295 individuals aged 18-78 years participated (22.5% of the overall adult population in Tasiilaq). Two-hundred and three participants (69%) had visible signs of current skin disease, and among these, 242 cases of dermatoses were identified. The most common skin diseases were hand eczema (22.4%), lichen simplex (9.5%), discoid eczema (7.1%), psoriasis, atopic dermatitis and acne vulgaris (5.8% each). Scabies was the most frequent infectious skin disease (4.4%). No cases of skin cancer were identified. Atopic dermatitis and psoriasis presented with disease that was of limited extent and different from the classical presentations. Skin diseases showed a high prevalence among adults in East Greenland, and some of them were severe. This indicates a noteworthy public health problem that warrants better access to dermatologist support.

Noncaloric monosaccharides induce excessive sprouting angiogenesis in zebrafish via foxo1a-marcksl1a signal.

Artificially sweetened beverages containing noncaloric monosaccharides were suggested as healthier alternatives to sugar-sweetened beverages. Nevertheless, the potential detrimental effects of these noncaloric monosaccharides on blood vessel function remain inadequately understood. We have established a zebrafish model that exhibits significant excessive angiogenesis induced by high glucose, resembling the hyperangiogenic characteristics observed in proliferative diabetic retinopathy (PDR). Utilizing this model, we observed that glucose and noncaloric monosaccharides could induce excessive formation of blood vessels, especially intersegmental vessels (ISVs). The excessively branched vessels were observed to be formed by ectopic activation of quiescent endothelial cells (ECs) into tip cells. Single-cell transcriptomic sequencing analysis of the ECs in the embryos exposed to high glucose revealed an augmented ratio of capillary ECs, proliferating ECs, and a series of upregulated proangiogenic genes. Further analysis and experiments validated that reduced foxo1a mediated the excessive angiogenesis induced by monosaccharides via upregulating the expression of marcksl1a. This study has provided new evidence showing the negative effects of noncaloric monosaccharides on the vascular system and the underlying mechanisms.

Consuming too much sugar can damage blood vessels and contribute to diseases like diabetes and heart disease. Artificial sweeteners have been suggested as a healthier alternative, and are now included in many products like sodas and baked goods. However, some studies have suggested that people who consume large amounts of artificial sweeteners also have an increased risk of cardiovascular disease. Others suggest individuals may also experience spikes in blood sugar levels similar to those observed in people with diabetes. Yet few studies have examined how artificial sweeteners affect the network of vessels that transport blood and other substances around the body. To investigate this question, Wang, Zhao, Xu, et al. studied zebrafish embryos which had been exposed to sugar and a type of artificial sweetener known as non-caloric monosaccharides. Various imaging tools revealed that high levels of sugar caused the embryos to produce more new blood vessels via a process called angiogenesis. This excessive growth of blood vessels has previously been linked to diabetic complications, including cardiovascular disease. Wang, Zhao, Xu, et al. found that zebrafish embryos exposed to several different non-caloric monosaccharides developed similar blood vessel problems. All the sweeteners tested caused immature cells lining the blood vessels to develop into active tip cells that promote angiogenesis. This led to more new blood vessels forming that branch off already existing veins and arteries. These findings suggest that artificial sweeteners may cause the same kind of damage to blood vessels as sugar. This may explain why people who consume a lot of artificial sweeteners are at risk of developing heart disease and high blood sugar levels. Future studies could help scientists learn more about how genetics or other factors affect the health impact of sugars and artificial sweeteners. This may lead to a greater understanding of the long-term health effects of artificially sweetened foods.

Breaking Barriers: Ensuring Gender Neutral Care on Short Term Surgical Missions.

INTRODUCTION: Gender discrimination is prevalent worldwide in medical and surgical care. In the setting of short-term surgical missions (STSMs) conducted to address the global burden of surgical disease, patient selection raises ethical considerations regarding equitable distribution of limited clinical resources. The goal of this study was to examine if equitable distribution of operative care between male and female patients occurs in STSMs. METHODS: The International Surgical Health Initiative (ISHI) is a US based nonprofit, nongovernmental organization. Records from surgical missions to Ghana (2014-2023) and Sierra Leone (2013-2023) were analyzed to evaluate for gender equity in inguinal hernia repairs, the most common procedure performed. A control group was created from a literature review inclusive of all studies of inguinal hernia repairs that included over 500 patients and patient gender. RESULTS: The review of 26 studies, representing 3,239,043 patients, demonstrated a gender distribution of 13% female. In Sierra Leone 246 inguinal hernia repairs were performed between 2013 and 2023. 28 (11.4%) of the hernia repairs were in females, which was not significantly different from the control group (P = 0.45). In Ghana 150 inguinal hernia repairs were performed between 2014 and 2023. 12 (8%) of the hernia repairs were in females. This was not significantly different from the control group (P = 0.07). CONCLUSIONS: This is the first study investigating the gender equity conducted within the context of humanitarian surgical outreach. Equitable patient selection is a paramount consideration in STSMs, particularly to address gender-related disparities in surgical care.

Leveraging a Global Partnership to Address COVID-19-Related Mental Health Challenges.

INTRODUCTION: The COVID-19 pandemic profoundly affected nurses globally. As frontline workers, nurses faced increased responsibilities amid challenges such as isolation, infection risks, family obligations and disrupted social support systems. Coping with these challenges was associated with adverse mental health outcomes. AIM/QUESTION: This perspective paper examines a collaboration between two schools of nursing in the United States and India to address these mental health challenges. METHODS: Faculty from both institutions identified key mental health topics, leading to five webinars that delved into topics such as acute and long-term impacts of COVID-19 on nurse mental health, coping mechanisms, caregiving responsibilities and children's needs during the pandemic. RESULTS: Impressively, over 11,000 nurses from 60 countries engaged, fostering a global platform for sharing evidence-based knowledge, experiences and strategies. IMPLICATIONS FOR PRACTICE: This partnership exemplifies the value of international collaboration. By pooling resources and expertise across cultural contexts, the initiative not only disseminated crucial knowledge but also cultivated a sense of global community among nurses. The success of this collaboration underscores the potential of such global partnerships for healthcare institutions worldwide, offering avenues to share best practices and enhance support systems for nurses confronting similar crises globally.

Learning from the Montreal Protocol to improve the global governance of antimicrobial resistance.

The Montreal Protocol has played a critical role in promoting global collective action to phase out the use of ozone-depleting substances, ultimately preventing millions of cases of skin cancer, cataracts and other health issues related to ultraviolet radiation exposure. This success entails transferable lessons for coordinated action required to improve the global governance of other challenges. Like ozone depletion, antimicrobial resistance (AMR) is a challenge of the global commons, requiring coordinated actions across human, animal and environmental sectors. We identify equity, flexibility and accountability as three core governance principles that underlie the success of the protocol and employ the 3-i framework to understand how interests, ideas and institutions contributed to the protocol's success. Equity-promoting strategies consisted of an inclusive negotiation process, supporting developing countries with multilateral funding and a progressive compliance model. Flexibility was built into the protocol through the development of country-specific strategies, reorienting incentive structures for industry and facilitating regular amendments in response to emerging scientific evidence. Accountability was promoted by mobilising public advocacy, establishing targets and enforcement mechanisms and conducting independent scientific and technical assessments. Applying our proposed principles presents an opportunity to improve the global governance of AMR. Finally, we acknowledge limitations to our analysis, including our focus on a single environmental treaty, significantly greater funding requirements and multifacetted stakeholder involvement in the case of AMR, differing market and incentives structures in antibiotic development and distribution, and ethical concerns with using trade restrictions as a policy tool.

Cost-effectiveness of surgical interventions in low-income and middle-income countries: a systematic review and critical analysis of recent evidence.

BACKGROUND: Cost-effectiveness evidence is a critical tool to support resource allocation decisions. There is growing recognition that the development of benefit packages for surgical care should be guided by such evidence, particularly in resource-constraint settings. METHODS: We conducted a systematic review of evidence (Medline, Embase, Global Health, EconLit and grey literature) on the cost-effectiveness of surgery across low-income and middle-income countries published between January 2013 and January 2023. We included studies with minor and major therapeutic surgeries and minimally invasive intraluminal and endovascular interventions. We computed and compared the average cost-effectiveness ratios (ACERs) for different surgical interventions to the respective national gross domestic product per capita to determine cost-effectiveness and to common traditional public health interventions. RESULTS: We identified 87 unique studies out of 20 070 articles screened. Studies spanned 23 countries, with China (n=20), Thailand (n=12), Brazil (n=8) and Iran (n=8) accounting for about 55% of the evidence. Overall, the median ACERs across procedure groups ranged from I$17/disability-adjusted life year (DALY) for laparotomies to I$170 186/DALY for bariatric surgeries. Most of the ACER estimates were classified as cost-effective (89%) or very cost-effective (76%). Low-complexity surgical interventions compared favourably to common public health interventions. CONCLUSION: These findings reinforce the growing body of evidence that investments in surgery are economically smart. There remains however paucity of high-quality evidence that would allow decision-makers to assess the comparative cost-effectiveness of surgery and to determine best buys across a wide range of specialties and interventions. A concerted effort is needed to advance the generation and utilisation of economic evidence in the drive towards scale-up of surgical care across low-income and middle-income countries.

Epidemiology of Intermediate Uveitis.

Intermediate uveitis is defined as inflammation of the vitreous and pars planitis. Etiology can be infectious, associated with a systemic disease, neoplastic or idiopathic. Pars planitis is the term used for idiopathic intermediate uveitis that presents with snowballs and snowbanks. While relatively rare, intermediate uveitis is present globally and typically affects adult females. Awareness of the presentation and a dilated fundus examination in patients presenting with floaters is essential to the diagnosis. PCR testing has enhanced the ability to diagnose infectious and neoplastic conditions that masquerade as intermediate uveitis. A structured review of systems and focused imaging, and laboratory testing will assist with early diagnosis and initiation of treatment.

A qualitative study of nurse participation in global health in the English NHS: participation, interest, and barriers to participation.

BACKGROUND: Nurses contribute to the largest demographic of the healthcare workforce. However, given current global shortages of workforce capacity, this often leads to limited capacity to engage in extracurricular educational developments beyond their immediate role. Consequently, this significantly limits the range of workforce training and development opportunities that are available to them, which could enhance the variety of skills that are brought to the National Health Service (NHS). OBJECTIVE: We aimed to understand prior, current, and future participation in global health activities such as global health conferences, networks, and placements, among National Health Service (NHS) staff. Furthermore, we investigated the barriers and facilitators to participation in global health activities for nurses in our sample. METHOD: Qualitative and quantitative data was gathered from an online survey conducted in England from July to November 2021. Thematic analysis was used to examine the qualitative data collected from one open-ended question, whereas statistical analysis was used to examine the remaining quantitative data. RESULTS: Most (84%) nurses in our sample had not participated in a global health activity. Our results highlighted three barriers to participation, including insufficient communication, a lack of awareness, and capacity issues. CONCLUSION: This study showed that, despite low levels of prior participation, there is a strong desire among surveyed nurses to be involved in global health activities and education. Our findings also suggest that enhanced communication of opportunities available is needed, in addition to organisational support which incorporates strategies to overcome capacity constraints.

The path to sustainable cardiac surgery in Rwanda: analysis of costs for consumables used during cardiac surgery for a non-governmental organization.

BACKGROUND: Until local healthcare infrastructure is strengthened, cardiac surgical care in low- and middle-income countries is often provided by non-governmental organizations by way of visiting healthcare teams. This is generally considered to be a cost-effective alternative to transporting patients to high income countries for surgical care, but the costs of cardiac surgery consumables under this model are poorly understood. Our objective was to identify the per-patient cost of cardiac surgery consumables used in single and double valve replacements performed by a non-governmental organization in Rwanda. METHODS: Financial data from 2020 were collected from Team Heart, a non-governmental organization that supports cardiac surgical care in Rwanda. A comprehensive list of consumables was generated, including surgical, perfusion, anesthesia, and inpatient supplies and medications. Acknowledging the variability in perioperative needs, the quantities of consumables were calculated from an average of six patients who underwent single or double-valve replacement in 2020. Total costs were calculated by multiplying purchasing price by average quantity per patient. Costs absorbed by the local hospital were excluded from the calculations. RESULTS: The total cost per patient was estimated at $9,450. Surgical supplies comprised the majority of costs ($6,140 per patient), with the most substantial cost being that of replacement valves ($3,500 per valve), followed by surgical supplies ($1,590 per patient). CONCLUSIONS: This preliminary analysis identifies a cost of just over $9,000 per patient for consumables used in cardiac valve surgery in Rwanda, which is lower than the estimated costs of transporting patients to centers in high income countries. This work highlights the relative cost effectiveness of cardiac surgical care in low- and middle- income countries under this model and will be instrumental in guiding the allocation of local and international resources in the future.

Water, sanitation and hygiene (WASH): the evolution of a global health and development sector.

Despite some progress, universal access to safe water, sanitation and hygiene (WASH) by 2030-a remit of Sustainable Development Goal 6-remains a distant prospect in many countries. Policy-makers and implementers of the WASH sector are challenged to track a new path. This research aimed to identify core orienting themes of the sector, as legacies of past processes, which can provide insights for its future. We reviewed global policy, science and programmatic documents and carried out 19 expert interviews to track the evolution of the global WASH sector over seven decades. We situated this evolution in relation to wider trends in global health and development over the same time period.With transnational flows of concern, expertise and resources from high-income to lower-income countries, the WASH sector evolved over decades of international institutionalisation of health and development with (1) a focus on technologies (technicalisation), (2) a search for generalised solutions (universalisation), (3) attempts to make recipients responsible for environmental health (responsibilisation) and (4) the shaping of programmes around quantifiable outcomes (metricisation). The emergent commitment of the WASH sector to these core themes reflects a pragmatic response in health and development to depoliticise poverty and social inequalities in order to enable action. This leads to questions about what potential solutions have been obscured, a recognition which might be understood as 'uncomfortable knowledge'-the knowns that have had to be unknown, which resonate with concerns about deep inequalities, shrinking budgets and the gap between what could and has been achieved.

The impact of a multi-faceted intervention on non-prescription dispensing of antibiotics by urban community pharmacies in Indonesia: a mixed methods evaluation.

INTRODUCTION: Non-prescription antibiotic dispensing is prevalent among community pharmacies in several low- and middle-income countries. We evaluated the impact of a multi-faceted intervention to address this challenge in urban community pharmacies in Indonesia. METHODS: A pre-post quasi-experimental study was carried out in Semarang city from January to August 2022 to evaluate a 7-month long intervention comprising: (1) online educational sessions for pharmacists; (2) awareness campaign targeting customers; (3) peer visits; and (4) pharmacy branding and pharmacist certification. All community pharmacies were invited to take part with consenting pharmacies assigned to the participating group and all remaining pharmacies to the non-participating group. The primary outcome (rate of non-prescription antibiotic dispensing) was measured by standardised patients displaying symptoms of upper respiratory tract infection, urinary tract infection (UTI) and seeking care for diarrhoea in a child. χ2 tests and multivariate random-effects logistic regression models were conducted. Thirty in-depth interviews were conducted with pharmacists, staff and owners as well as other relevant stakeholders to understand any persistent barriers to prescription-based dispensing of antibiotics. FINDINGS: Eighty pharmacies participated in the study. Postintervention, non-prescription antibiotics were dispensed in 133/240 (55.4%) consultations in the participating group compared with 469/570 (82.3%) in the non-participating group (p value <0.001). The pre-post difference in the non-prescription antibiotic dispensing rate in the participating group was 20.9% (76.3%-55.4%) compared with 2.3% (84.6%-82.3%) in the non-participating group (p value <0.001).Non-prescription antibiotics were less likely to be dispensed in the participating group (OR=0.19 (95% CI 0.09 to 0.43)) and more likely to be dispensed for the UTI scenario (OR=3.29 (95% CI 1.56 to 6.94)). Barriers to prescription-based antibiotic dispensing included fear of losing customers, customer demand, and no supervising pharmacist present. INTERPRETATION: Multifaceted interventions targeting community pharmacies can substantially reduce non-prescription antibiotic dispensing. Future studies to evaluate the implementation and sustainability of this intervention on a larger scale are needed.

The challenging concept of eradication: A core concept guiding and frustrating public health.

The celebrated 1980 announcement that smallpox had been eradicated was made using the following definition of eradication: "Permanent reduction to zero of the worldwide incidence of infection caused by a specific agent as a result of deliberate efforts: intervention measures are no longer needed." Public health around the world works with this definition of "eradication," setting it as a goal for other infectious disease control programs. The definition is simple. Its application, however, has produced long-running and complex public health campaigns that threaten the commitment of funders, health care providers, and governments. In this paper, the authors demonstrate the disease-specific challenges of eradication through the example of the Global Polio Eradication Initiative (GPEI). While many deem eradication worth its high costs because it is the end of morbidity and mortality from a disease, it does not mean the end of disease control efforts. Public health must be prepared for the possibility of disease reoccurrence in the form of undetected natural reservoirs of disease, lab leaks from stored samples, bioterror attacks using stolen samples, and the synthetic recreation of microbes. This paper clarifies the role of reoccurrence prevention in eradication, calling for its addition in the definition of eradication.

RéSUMé: L'annonce célèbre de 1980 que la variole a été éradiquée utilisait la définition d'éradication suivante : « Réduction permanente à zero de l'incidence mondiale d'infection causée par un agent spécifique en conséquence d'efforts délibérés : mesures d'intervention ne sont plus nécessaires. ¼ La santé publique globale emploie cette définition de « éradication ¼, la fixant comme objectif pour d'autres programmes de contrôle des maladies transmissibles. La définition est simple. Pourtant, son application a produit des campagnes de santé publique complèxes et de longues durées, qui menacent l'engagement des bailleurs de fonds, les prestataires des soins de santé, et les gouvernements. Dans cet article savant, les auteurs démontrent les obstacles d'éradication spécifiques à une maladie transmissible à travers l'exemple de la Global Polio Eradication Initiative (GPEI). Tandis que l'éradication pourrait peut-être mériter les côuts élevés associés puisqu'elle signifie la fin de la morbidité et la mortalité d'une infection, ceci ne représente pas la fin des efforts de contrôle des maladies. La santé publique doit se préparer pour la possibilité de la réapparition d'une maladie infectieuse en forme de reservoir de maladie naturel non-détecté, fuites de laboratoires des échantillons conservés, attaques bioterroristes utilisant des échantillons volés, et la récréation synthétique des microbes. Cet article savant clarifie le rôle de la prévention de réocurrence dans l'éradication, et demande que ce role soit ajouté à la definition d'éradication.

Projected impact of climate change on human health in low- and middle-income countries: a systematic review.

Low- and middle-income countries (LMICs) contribute relatively little to global carbon emissions but are recognised to be among the most vulnerable parts of the world to health-related consequences of climate change. To help inform resilient health systems and health policy strategies, we sought to systematically analyse published projections of the impact of rising global temperatures and other weather-related events on human health in LMICs. A systematic search involving multiple databases was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to identify studies with modelled projections of the future impact of climate change on human health. Qualitative studies, reviews and meta-analyses were excluded. The search yielded more than 2500 articles, of which 70 studies involving 37 countries met criteria for inclusion. China, Brazil and India were the most studied countries while the sub-Saharan African region was represented in only 9% of studies. Forty specific health outcomes were grouped into eight categories. Non-disease-specific temperature-related mortality was the most studied health outcome, followed by neglected tropical infections (predominantly dengue), malaria and cardiovascular diseases. Nearly all health outcomes studied were projected to increase in burden and/or experience a geographic shift in prevalence over the next century due to climate change. Progressively severe climate change scenarios were associated with worse health outcomes. Knowledge gaps identified in this analysis included insufficient studies of various high burden diseases, asymmetric distribution of studies across LMICs and limited use of some climate parameters as independent variables. Findings from this review could be the basis for future research to help inform climate mitigation and adaptation programmes aimed at safeguarding population health in LMICs.

Cooperators or competitors? The interactions between WHO and the World Bank in global health governance.

Interactions between International Organisations (IOs) within a regime complex often manifest themselves through competition and cooperation. Current research has examined the factors that promote inter-organisational competition and cooperation, yet the precise timing of when such competition or cooperation commences remains unclear. This paper focuses on two pivotal IOs in global health governance, the World Health Organization (WHO) and the World Bank, to explore the timing and onset of competition and cooperation within a regime complex, as well as the driving factors in the evolution of their inter-organisational relationships. By looking into the interactions between the WHO and the World Bank in norm-setting and resource mobilising, the paper sheds light on how their relationships have transitioned from competitors to cooperators. It systematically presents the mechanisms and processes of policy transformation in inter-organisational interactions. As a new agenda arises, IOs within a regime complex often compete for dominance, with ideational differences driving them to propose and implement distinct governance strategies. They will compete for resources and mainstream of their strategy. The negative spillover effects of competitive policies consequently undermine the effectiveness of IOs' policy, thereby undercut their legitimacy. To surmount these challenges, the international community should promote inter-institutional coordination in global governance.
