Introduction Community health workers (CHWs) are increasingly being tasked to prevent and manage cardiovascular disease (CVD) and its risk factors in underserved populations in low-income and middle-income countries (LMICs); however, little is known about the required training necessary for them to ...accomplish their role. This review aimed to evaluate the training of CHWs for the prevention and management of CVD and its risk factors in LMICs.
Methods A search strategy was developed in line with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, and five electronic databases (Medline, Global Health, ERIC, EMBASE and CINAHL) were searched to identify peer-reviewed studies published until December 2016 on the training of CHWs for prevention or control of CVD and its risk factors in LMICs. Study characteristics were extracted using a Microsoft Excel spreadsheet and quality assessed using Effective Public Health Practice Project’s Quality Assessment Tool. The search, data extraction and quality assessment were performed independently by two researchers.
Results The search generated 928 articles of which 8 were included in the review. One study was a randomised controlled trial, while the remaining were before–after intervention studies. The training methods included classroom lectures, interactive lessons, e-learning and online support and group discussions or a mix of two or more. All the studies showed improved knowledge level post-training, and two studies demonstrated knowledge retention 6 months after the intervention.
Conclusion The results of the eight included studies suggest that CHWs can be trained effectively for CVD prevention and management. However, the effectiveness of CHW trainings would likely vary depending on context given the differences between studies (eg, CHW demographics, settings and training programmes) and the weak quality of six of the eight studies. Well-conducted mixed-methods studies are needed to provide reliable evidence about the effectiveness and cost-effectiveness of training programmes for CHWs.

Background
Low- and middle-income countries now experience the highest prevalence and mortality rates of cardiovascular disease.
Main text
While improving the availability and delivery of proven, effective therapies will no doubt mitigate this burden, we posit that studies evaluating cardiovasc...ular disease risk factors, management strategies and service delivery, in diverse settings and diverse populations, are equally critical to improving outcomes in low- and middle-income countries. Focusing on examples drawn from four cardiovascular diseases — coronary artery disease, stroke, diabetes and kidney disease — we argue that ethnicity, culture and context matter in determining the risk factors for disease as well as the comparative effectiveness of medications and other interventions, particularly diet and lifestyle interventions.
Conclusion
We believe that a host of cohort studies and randomized control trials currently being conducted or planned in low- and middle-income countries, focusing on previously understudied race/ethnic groups, have the potential to increase knowledge about the cause(s) and management of cardiovascular diseases across the world.

Socioeconomic status is associated with differences in risk factors for cardiovascular disease incidence and outcomes, including mortality. However, it is unclear whether the associations between cardiovascular disease and common measures of socioeconomic status—wealth and education—differ among... high-income, middle-income, and low-income countries, and, if so, why these differences exist. We explored the association between education and household wealth and cardiovascular disease and mortality to assess which marker is the stronger predictor of outcomes, and examined whether any differences in cardiovascular disease by socioeconomic status parallel differences in risk factor levels or differences in management.

Global cardiovascular disease (CVD) burden is high and rising, especially in low-income and middle-income countries (LMICs). Focussing on 45 LMICs, we aimed to determine (1) the adult population’s median 10-year predicted CVD risk, including its variation within countries by socio-demographic char...acteristics, and (2) the prevalence of self-reported blood pressure (BP) medication use among those with and without an indication for such medication as per World Health Organization (WHO) guidelines.

Asthma is the most common chronic respiratory disease (CRD) worldwide and is estimated to affect 262 million causing significant mortality and morbidity, and has emerged as an important public health problem in many Latin American (LA) countries over the last 30 or so years. LA is a highly diverse r...egion in terms of geography, climate, wealth, and ethnicity including 20 different countries with 639 million inhabitants, where 40 million are estimated to have asthma. A common feature of LA countries is the high level of social inequalities3 (Figure 1). In LA, asthma prevalence in both children and adults is highly variable and, where high, is among the highest worldwide, particularly in coastal tropical cities.

This status report shows how far we have come—and how much further we must go—if we hope to meet the global commitments to end AIDS in children. It offers a snapshot of global progress and permits an early assessment of the impact of the Global Alliance’s work.
This UNAIDS 2024 report brings together new data and case studies which demonstrate that the decisions and policy choices taken by world leaders this year will decide the fate of millions of lives and whether the world’s deadliest pandemic is overcome.
COVID-19 has altered health sector capacity in low-income and middle-income countries (LMICs). Cost data to inform evidence-based priority setting are urgently needed. Consequently, in this paper, we calculate the full economic health sector costs of COVID-19 clinical management in 79 LMICs under di...fferent epidemiological scenarios.

Public health emergencies, including pandemics, highlight the need for health systems and services that are prepared, resilient and ready to respond to health security threats. Endorsed by Member States in 2023, the Asia Pacific Health Security Action Framework (APHSAF) is designed to engage m...ultisectoral actors in health security, and to reflect the complex nature of current and future public health emergencies. The Framework presents six interconnected, multisectoral domains of work that together form a comprehensive, multi-hazard health security system — emphasizing the One Health approach. The Framework also supports progress towards the Sustainable Development Goals and universal health coverage while meeting the responsibilities and obligations of the International Health Regulations (2005).

Health system resilience is not an inevitable byproduct of any investment in health but must be intentionally programmed and developed with necessary input, investment and contextualization. This technical product aims to guide national, subnational, and global health actors to operationalize the co...ncept of health system resilience for advancement of universal health coverage, health security and ultimately better health for all. It supports the translation of relevant conceptual guidance and high-level recommendations into practical actions.
The specific objectives are to:
present a concise overview of the concept of health system resilience;
provide a roadmap outlining practical and foundational steps for building health system resilience to be adapted to different contexts;
share examples of actions and tools, including stakeholder roles, to support country application of the roadmap.
The target audience for this work is the various stakeholders involved in strengthening health systems and public health including management of emergencies (from prevention and preparedness to response and recovery) and other public health challenges in countries. This ranges from the donors, policy-makers and decision-makers at global, national and subnational levels to the implementing institutions and line managers of health system functions and services across the health system building blocks.

The results of the report clearly show that in 2020, a year dominated by the emergence of COVID-19 and its associated health and economic crises, governments around the world rose to the challenge. Sharp increases in government spending on health at all country income levels underpinned the rise in ...health spending to a new high of US $9 trillion (approximately 11% of global GDP). Government health spending generally increased and offset declines in out-of-pocket spending. Importantly, the rise in government health spending was part of a much broader fiscal response to the pandemic. In high income and upper-middle income countries social protection spending also increased sharply in as governments attempted to cushion populations from the economic impacts of COVID-19. In contrast to health and social protection, growth in education spending was relatively subdued. Countries face the further challenge of sustaining increased public spending on health and other social sectors in the face of deteriorating macroeconomic conditions and rising debt servicing. This also includes the challenge of sustaining external support for low income countries, which is essential for reducing ensuring poverty, ensuring access to health services and strengthening pandemic preparedness.

Diphtheria is caused by Corynebacterium species, mostly by toxin-producing Corynebacterium diphtheriae and rarely by toxin-producing strains of C. ulcerans and C. pseudotuberculosis. The most common type of diphtheria is classic respiratory diphtheria, whereby the exotoxin produced characteristicall...y causes the formation of a pseudomembrane in the upper respiratory tract and damages other organs, usually the myocardium and peripheral nerves. Acute respiratory obstruction, acute systemic toxicity, myocarditis and neurologic complications are the usual causes of death. The infection can also affect the skin (cutaneous diphtheria). More rarely, it can affect mucous membranes at other non-respiratory sites, such as genitalia and conjunctiva.
C. diphtheriae is transmitted from person to person by intimate respiratory and direct contact; in contrast, C. ulcerans and C. pseudotuberculosis are zoonotic infections, not transmitted person-to-person. The incubation period of C. diphtheriae is two to five days (range 1– 10 days). A person is infectious as long as virulent bacteria are present in respiratory secretions, usually two weeks without antibiotics, and seldom more than six weeks. In rare cases, chronic carriers may shed organisms for six months or more. Skin lesions are often chronic and infectious for longer periods. Effective antibiotic therapy (penicillin or erythromycin) promptly terminates shedding in about one or two days.

In 2019, the Global Fund’s 6th Replenishment raised more than $USD14 billion to fight HIV, Tuberculosis and Malaria. Just two years later, the world has changed significantly. Put simply: COVID-19 devastated prevention and treatment programs. For the first time since the Global Fund’s founding, ...in 2020 the world lost ground in the fight against HIV, Tuberculosis and Malaria.
The Global Fund moved quickly to support countries to respond to COVID-19 and its impact on the three diseases, repurposing and leveraging additional funding to support urgent needs and adapt programs. Despite those efforts, the need for action to resume progress in the fight against HIV, TB and malaria has never been greater.
The world faces a choice.
