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.

FHIRing up OpenMRS: Architecture, Implementation and Real-World Use-Cases in Global Health.

HL7 FHIR was created almost a decade ago and is seeing increasingly wide use in high income settings. Although some initial work was carried out in low and middle income (LMIC) settings there has been little impact until recently. The need for reliable and easy to implement interoperability between health information systems in LMICs is growing with large scale deployments of EHRs, national reporting systems and mHealth applications. The OpenMRS open source EHR has been deployed in more than 44 LMIC with increasing needs for interoperability with other HIS. We describe here the development and deployment of a new FHIR module supporting the latest standards and its use in interoperability with laboratory systems, mHealth applications, pharmacy dispensing system and as a tool for supporting advanced user interface designs. We also show how it facilitates date science projects and deployment of machine leaning based CDSS and precision medicine in LMICs.

Prevalence of Cardiovascular Risk Factors in Rural Kenya-2023: Vihiga II.

BACKGROUND: The aim of this study was to estimate the prevalence of cardiovascular disease (CVD) risk factors among adults in Vihiga County, Western Kenya. METHODS: A cross-sectional population-based study was completed. Participants (n = 575) were selected at the household level using a systematic random sample, and sociodemographic, anthropometrical, clinical, and biochemical data were collected. RESULTS: The sample consisted of 71.8% women and 28.2% men. The prevalence of high blood pressure (BP) was 56.4%. A greater proportion of women (62.8%) had low levels of high-density lipoprotein (HDL) compared with men (44.7%) (odds ratio [OR], 2.99; 95% CI, 1.59-5.64). High triglyceride levels were more prevalent in men (16.4%) compared with women (15.4%) (OR, 0.37; 95% CI, 0.19-0.71). Based on average waist to hip ratio, abdominal obesity was significantly higher in women (55.4%) compared with men (27.6%) (OR, 2.62; 95% CI, 1.52-4.49). Low levels of physical inactivity were prevalent in women (36.3%) at significantly higher proportions compared with men (22.7%) (OR, 1.73; 95% CI, 1.02-2.92). Women used tobacco at significantly lower proportions (0.5%) compared with men (27.2%) (OR, 0.01; 95% CI, 0.00-0.06). A higher proportion of women (47.9%) rated their general health as poor compared with men (37.1%), a statistically significant difference (OR, 2.0; 95% CI, 1.23-3.28). CONCLUSION: The prevalence of CVD risk factors, such as hypertension, obesity, dyslipidemia, low physical activity, and tobacco use indicates the urgent need for comprehensive health promotion programs to improve public health in rural areas of Kenya.

Achievement of Guideline-Recommended Targets for Secondary Prevention of Cardiovascular Disease in 38 Low-Income and Middle-Income Countries.

BACKGROUND: This study aimed to estimate the prevalence of achieving the secondary prevention targets recommended in the World Health Organization (WHO) guidelines for cardiovascular disease (CVD) in 38 low-income and middle-income countries (LMICs). METHODS: We pooled nationally representative cross-sectional surveys from 38 LMICs between 2013 and 2020. Treatment, metabolic and lifestyle targets were assessed for individuals with a self-reported history of CVD according to WHO's recommendations. Associations between the prevalence of guideline adherence and sociodemographic characteristics were assessed using multivariate Poisson regression models. RESULTS: The pooled sample included 126 106 participants, of whom 9821 (6.8% [95% CI 6.4-7.2]) reported a history of CVD. Overall, the prevalence of achieving treatment targets in patients with CVD was 22.7% (95% CI, 21.0-24.5%) for antihypertensive drugs, 19.6% (17.9-21.4%) for aspirin, and 13.6% (12.0-15.44%) for statins. The prevalence of achieving metabolic targets was 54.9% (52.5-57.3%) for BMI, 39.9% (37.7-42.2%) for blood pressure, 46.1% (43.6-48.6%) for total cholesterol, and 84.9% (83.1-86.5%) for fasting blood glucose. The prevalence of achieving lifestyle targets was 83.2% (81.5-84.7%) for not smoking, 83.1% (81.2-84.9%) for not drinking, 65.5% (63.1-67.7%) for sufficient physical activity and 16.2% (14.5-18.0%) for healthy diet. Only 6.1% (5.1-7.4%) achieved three treatment targets, 16.0% (14.3-17.9%) achieved four metabolic targets, and 6.9% (5.8-8.0%) achieved four lifestyle targets. Upper-middle income countries were better than low-income countries at achieving the treatment, non-drinking and dietary targets. Being younger and female were associated with poorer achievement of metabolic targets. CONCLUSION: In LMICs, achieving the targets recommended in the guideline for treatment, metabolism and healthy lifestyles for patients with CVD is notably low. This highlights an urgent need for effective, systematic secondary prevention strategies to improve CVD management.

Developing the OpenFlexure Microscope towards medical use: technical and social challenges of developing globally accessible hardware for healthcare.

The OpenFlexure Microscope is an accessible, three-dimensional-printed robotic microscope, with sufficient image quality to resolve diagnostic features including parasites and cancerous cells. As access to lab-grade microscopes is a major challenge in global healthcare, the OpenFlexure Microscope has been developed to be manufactured, maintained and used in remote environments, supporting point-of-care diagnosis. The steps taken in transforming the hardware and software from an academic prototype towards an accepted medical device include addressing technical and social challenges, and are key for any innovation targeting improved effectiveness in low-resource healthcare. This article is part of the Theo Murphy meeting issue 'Open, reproducible hardware for microscopy'.

Two decades of research capacity strengthening and reciprocal learning on sexual and reproductive health in East Africa - a point of (no) return.

As the world is facing challenges such as pandemics, climate change, conflicts, and changing political landscapes, the need to secure access to safe and high-quality abortion care is more urgent than ever. On 27th of June 2023, the Swedish government decided to cut funding resources available for developmental research, which has played a fundamental role in the advancement of sexual and reproductive health and rights (SRHR) globally, including abortion care. Withdrawal of this funding not only threatens the fulfilment of the United Nations sustainable development goals (SDGS) - target 3.7 on ensuring universal access to SRHR and target 5 on gender equality - but also jeopardises two decades of research capacity strengthening. In this article, we describe how the partnerships that we have built over the course of two decades have amounted to numerous publications, doctoral graduates, and important advancements within the field of SRHR in East Africa and beyond.

Main findings: The two-decade long collaboration between Sweden and East Africa, funded by the Swedish government, has resulted in important partnerships, research findings, and advancements within sexual and reproductive health and rights in East Africa.Added knowledge: The Swedish government is now cutting funding for development research, which jeopardises the progress made so far.Global health impact for policy and action: Governments need to prioritise women's sexual and reproductive health and rights.

The impact of surgery and oncological treatment on risk of type 2 diabetes onset in patients with colorectal cancer: nationwide cohort study in Denmark.

Background: Comorbidity with type 2 diabetes (T2D) results in worsening of cancer-specific and overall prognosis in colorectal cancer (CRC) patients. The treatment of CRC per se may be diabetogenic. We assessed the impact of different types of surgical cancer resections and oncological treatment on risk of T2D development in CRC patients. Methods: We developed a population-based cohort study including all Danish CRC patients, who had undergone CRC surgery between 2001 and 2018. Using nationwide register data, we identified and followed patients from date of surgery and until new onset of T2D, death, or end of follow-up. Results: In total, 46,373 CRC patients were included and divided into six groups according to type of surgical resection: 10,566 Right-No-Chemo (23%), 4645 Right-Chemo (10%), 10,151 Left-No-Chemo (22%), 5257 Left-Chemo (11%), 9618 Rectal-No-Chemo (21%), and 6136 Rectal-Chemo (13%). During 245,466 person-years of follow-up, 2556 patients developed T2D. The incidence rate (IR) of T2D was highest in the Left-Chemo group 11.3 (95% CI: 10.4-12.2) per 1000 person-years and lowest in the Rectal-No-Chemo group 9.6 (95% CI: 8.8-10.4). Between-group unadjusted hazard ratio (HR) of developing T2D was similar and non-significant. In the adjusted analysis, Rectal-No-Chemo was associated with lower T2D risk (HR 0.86 [95% CI 0.75-0.98]) compared to Right-No-Chemo.For all six groups, an increased level of body mass index (BMI) resulted in a nearly twofold increased risk of developing T2D. Conclusions: This study suggests that postoperative T2D screening should be prioritised in CRC survivors with overweight/obesity regardless of type of CRC treatment applied.

Country-specific determinants for COVID-19 case fatality rate and response strategies from a global perspective: an interpretable machine learning framework.

BACKGROUND: There are significant geographic inequities in COVID-19 case fatality rates (CFRs), and comprehensive understanding its country-level determinants in a global perspective is necessary. This study aims to quantify the country-specific risk of COVID-19 CFR and propose tailored response strategies, including vaccination strategies, in 156 countries. METHODS: Cross-temporal and cross-country variations in COVID-19 CFR was identified using extreme gradient boosting (XGBoost) including 35 factors from seven dimensions in 156 countries from 28 January, 2020 to 31 January, 2022. SHapley Additive exPlanations (SHAP) was used to further clarify the clustering of countries by the key factors driving CFR and the effect of concurrent risk factors for each country. Increases in vaccination rates was simulated to illustrate the reduction of CFR in different classes of countries. FINDINGS: Overall COVID-19 CFRs varied across countries from 28 Jan 2020 to 31 Jan 31 2022, ranging from 68 to 6373 per 100,000 population. During the COVID-19 pandemic, the determinants of CFRs first changed from health conditions to universal health coverage, and then to a multifactorial mixed effect dominated by vaccination. In the Omicron period, countries were divided into five classes according to risk determinants. Low vaccination-driven class (70 countries) mainly distributed in sub-Saharan Africa and Latin America, and include the majority of low-income countries (95.7%) with many concurrent risk factors. Aging-driven class (26 countries) mainly distributed in high-income European countries. High disease burden-driven class (32 countries) mainly distributed in Asia and North America. Low GDP-driven class (14 countries) are scattered across continents. Simulating a 5% increase in vaccination rate resulted in CFR reductions of 31.2% and 15.0% for the low vaccination-driven class and the high disease burden-driven class, respectively, with greater CFR reductions for countries with high overall risk (SHAP value > 0.1), but only 3.1% for the ageing-driven class. CONCLUSIONS: Evidence from this study suggests that geographic inequities in COVID-19 CFR is jointly determined by key and concurrent risks, and achieving a decreasing COVID-19 CFR requires more than increasing vaccination coverage, but rather targeted intervention strategies based on country-specific risks.

Rare case of human Ancylostoma ceylanicum infection in Bangladesh.

The zoonotic hookworm species Ancylostoma ceylanicum has drawn more attention recently because of its potential impact on public health. Although A. duodenale and Necator americanus are more common, A. ceylanicum is still known to play a major role in human infections, particularly in regions where close human-animal interactions are prevalent. While there has been a notable increase in documenting the presence of A. ceylanicum in the Asia-Pacific area, bottlenecks remains in understanding its epidemiology in Bangladesh. This report highlights the first documented case of Ancylostoma ceylanicum infection isolated and identified in a 15-year-old girl experiencing frequent diarrhea and weakness, residing in an urban tea garden area in Sylhet, Bangladesh. Microscopic examination of stool samples revealed the presence of hookworm eggs and subsequent culture led to the observation of larvae. Molecular investigation by amplifying Internal Transcribed Spacer (ITS1+) regions of the ribosomal deoxyribonucleic acid (rDNA) confirmed the infection as A. ceylanicum. The identification of Ancylostoma ceylanicum in a human host in Bangladesh carries significant implications for global health. The careful measurement of eggs and larvae, coupled with molecular analysis, serves as an appropriate diagnostic strategy for confirming the infections. This finding emphasizes the emergence of A. ceylanicum as a zoonotic infection in endemic regions and calls for increased awareness among healthcare professionals and the general public.

Global Mental Health and Immigrant Families.

There are few human tragedies that stir sympathy and concern more deeply than seeing children suffer secondary to war, displacement, and increasingly frequent epidemics of violence around the world. Falling witness or victim to acts of war and terrorism and subsequent fleeing of millions of children across the world stirs an array of powerful human emotions. Such circumstances by definition involve destruction, pain, and death. It is, paramount that we all work collaboratively, to provide psychological assistance, training, and education and work with various stakeholders to decrease the psychological impact of displacement secondary to war, terrorism, and other social factors.

The burden of alcohol-related cardiovascular complications in young and middle-aged adults: rising burden of atrial fibrillation and hypertensive heart disease.

BACKGROUND AND AIMS: The burden of alcohol-related complications is high and rising. However, there are notable deficiencies in comprehensive epidemiological study focusing on cardiovascular complications from alcohol, especially among young and middle-aged adults. We thus aimed to determine the burden of these conditions in young and middle-aged adults globally. METHODS AND RESULTS: We used data from the Global Burden of Disease Study 2019 and analysed the mortality and disability-adjusted life years of alcohol-associated cardiovascular complications in young and middle-aged adults. The findings were classified by sex, region, country, and Sociodemographic Index (SDI). The highest age-standardized death rates (ASDR) were observed in stroke 0.84 (95% UI 0.60-1.09), followed by alcoholic cardiomyopathy 0.57 (95% UI 0.47-0.66) per 100,000 population. The overall burden of alcohol-associated cardiovascular complications decreased globally but increased in atrial fibrillation and hypertensive heart disease. Regionally, most regions underwent a decrease in ASDR, but an increase was observed in Southeast Asia (+2.82%), Western Pacific (+1.48%), low-middle (+1.81%), and middle SDI (+0.75%) countries. Nevertheless, the ASDR and ASDALYs were highest in Europe. CONCLUSIONS: The impact of alcohol-associated atrial fibrillation and hypertensive heart disease has increased over the last decades. Regarding region, the burden in Europe and the rising burden in Asia, require immediate public health policy to lessen these cardiovascular complications from alcohol in young and middle-aged adults.

Open source approaches for pediatric global health technologies.

Access to medical technologies is a critical component of universal access to care; however, the advancement of technologies for children has historically lagged behind those for adults. The small market size, anatomic and physiologic variability, and legal and ethical implications pose unique barriers to developing and commercialising paediatric biomedical innovations. These challenges are magnified in low-resource settings (LRS), which often lack appropriate regulatory oversight, support for service contracts, and supply chain capacity. The COVID-19 pandemic exposed shortcomings in the traditional industry model for medical technologies, while also catalysing open-source approaches to technology development and dissemination. Open-source pathways - where products are freely licenced to be distributed and modified - addressed key shortages in critical equipment. Relatedly, we argue that open-source approaches can accelerate paediatric global health technology development. Open-source approaches can be tailored to clinical challenges independent of economic factors, embrace low-cost manufacturing techniques, and can be highly customisable. Furthermore, diverse stakeholders, including families and patients, are empowered to participate in collaborative communities of practice. How to regulate the development, manufacture, and distribution of open-source technologies remains an ongoing area of exploration. The need for democratised innovation must be carefully balanced against the imperatives of safety and quality for paediatric-specific solutions. This can be achieved, in part, through close coordination between national regulatory agencies and decentralised networks where products can be peer-reviewed and tested. Altogether, there is significant potential for open source to advance more equitable and sustainable medical innovations for all children.

Misstatements, misperceptions, and mistakes in controlling for covariates in observational research.

We discuss 12 misperceptions, misstatements, or mistakes concerning the use of covariates in observational or nonrandomized research. Additionally, we offer advice to help investigators, editors, reviewers, and readers make more informed decisions about conducting and interpreting research where the influence of covariates may be at issue. We primarily address misperceptions in the context of statistical management of the covariates through various forms of modeling, although we also emphasize design and model or variable selection. Other approaches to addressing the effects of covariates, including matching, have logical extensions from what we discuss here but are not dwelled upon heavily. The misperceptions, misstatements, or mistakes we discuss include accurate representation of covariates, effects of measurement error, overreliance on covariate categorization, underestimation of power loss when controlling for covariates, misinterpretation of significance in statistical models, and misconceptions about confounding variables, selecting on a collider, and p value interpretations in covariate-inclusive analyses. This condensed overview serves to correct common errors and improve research quality in general and in nutrition research specifically.

Paving the path for implementation of clinical genomic sequencing globally: Are we ready?

Despite the emerging evidence in recent years, successful implementation of clinical genomic sequencing (CGS) remains limited and is challenged by a range of barriers. These include a lack of standardized practices, limited economic assessments for specific indications, limited meaningful patient engagement in health policy decision-making, and the associated costs and resource demand for implementation. Although CGS is gradually becoming more available and accessible worldwide, large variations and disparities remain, and reflections on the lessons learned for successful implementation are sparse. In this commentary, members of the Global Economics and Evaluation of Clinical Genomics Sequencing Working Group (GEECS) describe the global landscape of CGS in the context of health economics and policy and propose evidence-based solutions to address existing and future barriers to CGS implementation. The topics discussed are reflected as two overarching themes: (1) system readiness for CGS and (2) evidence, assessments, and approval processes. These themes highlight the need for health economics, public health, and infrastructure and operational considerations; a robust patient- and family-centered evidence base on CGS outcomes; and a comprehensive, collaborative, interdisciplinary approach.

Mobile health-delivered narrative intervention to increase cervical cancer screening among Malawian women living with HIV: A pilot randomized controlled trial.

Objective: This study aimed to develop and evaluate a mobile health (mHealth)-delivered, theory-guided, culturally tailored storytelling narrative (STN) intervention to increase cervical cancer screening among Malawian women living with human immunodeficiency virus (HIV). Methods: This study involved two phases: Phase 1: development of a theory-guided and culturally adapted STN intervention and Phase 2: a pilot randomized controlled trial was conducted. Participants were randomly assigned to one of three arms: Arm 1: tablet-based video (mHealth) with STN (n = 60); Arm 2: mHealth with a video of nonnarrative educational materials (n = 59); and Arm 3: control group with only reading nonnarrative educational materials in person (n = 60). Cervical cancer screening was measured using visual inspection with acetic acid (VIA) uptakes by self-report and health passport record review at 2 and 6 months after intervention. Results: Both arms 1 and 2 had nearly twice the rate of VIA uptakes than those in Arm 3 (51.0% and 50.0%, respectively, vs. 35.0%, P = 0.01) at 2 months follow-up, but there were no differences among groups from 2- to 6-month follow-ups. All groups demonstrated significant improvement of knowledge about risk factors, intention, and VIA uptakes. Conclusions: The findings demonstrate the preliminary effectiveness of the intervention on cervical cancer screening behavior and the feasibility of the study regarding recruitment, retention, treatment fidelity, and acceptability of the single 30-min session. The feasibility and the preliminary results of the effectiveness of the proposed study indicate scaling up the STN intervention to a larger population of women to increase cervical cancer screening uptake to prevent deaths due to cervical cancer in Malawi.

Emerging and Reemerging Parasitic Diseases in Taiwan: A Retrospective Study of Clinical Case Reports in 2001~2018.

Emerging and re-emerging parasitic diseases can cause significant economic burdens at national and global levels. However, governments often underestimate or ignore these diseases, especially in developed countries. This retrospective, case-oriented study analyzed parasitic diseases reported in Taiwan between 2001 and 2018. One hundred and thirty-two eligible clinical profiles of Taiwanese patients obtained from the NCBI, Scopus, Google Scholar, and Web of Science databases and local journals according to age, sex, source of infection, symptoms, risk factors, and geographical regions were analyzed. The analysis results showed that the number/frequency of cases caused by nematodes (46.97%) or protozoa (37.88%) was significantly higher than that of trematodes (9.85%) or cestodes (5.30%) (p < 0.0001). Northern Taiwan (46.97%) had a significantly higher rate than Southern Taiwan (33.33%), Central Taiwan (8.33%), and Eastern Taiwan (5.30%) (p < 0.05). The 15-65 age group (68.94%) had a significantly higher rate than the 65-90 age group (22.73%) and the 0-15 age group (8.33%) (p < 0.0001). Males (70.46%) had a significantly higher number/frequency of cases than females (29.54%) (p < 0.0001). People who acquired the infection through the food/soil route (32.58%) or who had a low immune status (32.58%) had a higher rate than travel-related infections (15.15%) (p < 0.001). The present study showed that emerging/reemerging parasitic infections continue to be of great concern to the lives and health of Taiwanese citizens and, if ignored, will threaten the health of the Taiwanese people; therefore, the delineation of preventive measures by health authorities is urgently warranted.

An overview of the perspectives used in health economic evaluations.

The term 'perspective' in the context of economic evaluations and costing studies in healthcare refers to the viewpoint that an analyst has adopted to define the types of costs and outcomes to consider in their studies. However, there are currently notable variations in terms of methodological recommendations, definitions, and applications of different perspectives, depending on the objective or intended user of the study. This can make it a complex area for stakeholders when interpreting these studies. Consequently, there is a need for a comprehensive overview regarding the different types of perspectives employed in such analyses, along with the corresponding implications of their use. This is particularly important, in the context of low-and-middle-income countries (LMICs), where practical guidelines may be less well-established and infrastructure for conducting economic evaluations may be more limited. This article addresses this gap by summarising the main types of perspectives commonly found in the literature to a broad audience (namely the patient, payer, health care providers, healthcare sector, health system, and societal perspectives), providing their most established definitions and outlining the corresponding implications of their uses in health economic studies, with examples particularly from LMIC settings. We then discuss important considerations when selecting the perspective and present key arguments to consider when deciding whether the societal perspective should be used. We conclude that there is no one-size-fits-all answer to what perspective should be used and the perspective chosen will be influenced by the context, policymakers'/stakeholders' viewpoints, resource/data availability, and intended use of the analysis. Moving forward, considering the ongoing issues regarding the variation in terminology and practice in this area, we urge that more standardised definitions of the different perspectives and the boundaries between them are further developed to support future studies and guidelines, as well as to improve the interpretation and comparison of health economic evidence.
