The global prevalence, morbidity and mortality related to childhood asthma among children has increased significantly over the last 40 years. Although asthma is recognized as the most common chronic disease in children, issues of underdiagnosis and undertreatment persist. There are substantial globa...l variations in the prevalence of asthma symptoms in children, with up to 13-fold differences between countries. The rising number of hospital admissions for asthma may reflect an increase in asthma severity, poor disease management and/or the effect of poverty. The financial burden of asthma is relatively high within developed countries (those for which data is available) spending 1 to 2% of their healthcare budget on this condition. Established in 1989, the Global Initiative for Asthma (GINA) attempts to raise awareness about the increasing prevalence of asthma, improve management and reduce the burden of asthma worldwide. Despite global efforts, GINA has not achieved its goal, even among developed nations. There are multiple barriers to reducing the global burden of asthma, including limited access to care and/or medications, and lack of prioritization as a public healthcare priority. In addition, the diversity of healthcare systems worldwide and large differences in access to care require that asthma management guidelines be tailored to local needs.

INTRODUCTION: Lower extremity peripheral artery disease (PAD) is increasing in prevalence in low- and middle-income countries creating a large health care burden. Clinical management may require substantial resources but little consideration has been given to which treatments are appropriate for les...s advantaged countries.
EVIDENCE ACQUISITION: The aim of this review was to systematically appraise published data on the costs and effectiveness of PAD treatments used commonly in high-income countries, and for an international consensus panel to review that information and propose a hierarchy of treatments relevant to low- and middle-income countries.
EVIDENCE SYNTHESIS: Pharmacotherapy for intermittent claudication was found to be expensive and improve walking distance by a modest amount. Exercise and endovascular therapies were more effective and exercise the most cost-effective. For critical limb ischemia, bypass surgery and endovascular therapy, which are both resource intensive, resulted in similar rates of amputation-free survival. Substantial reductions in cardiovascular events occurred with use of low cost drugs (statins, ACE inhibitors, anti-platelets) and smoking cessation.
CONCLUSIONS: The panel concluded that, in low- and middle-income countries, cardiovascular prevention is a top priority, whereas a lower priority should be given to pharmacotherapy for leg symptoms and revascularisation, except in countries with established vascular units.

Despite progress in improving antiretroviral therapy (ART) for people with HIV in Malawi, the burden of HIV infections and HIV treatment outcomes among key populations is suboptimal. Client-centered differentiated service delivery approaches may facilitate addressing HIV prevention and treatment nee...ds of key populations in Malawi.
Methods
De-identified program data routinely collected as part of the LINKAGES project–Malawi were assembled from October 2017 to September 2019. HIV case finding was compared across different testing modalities for each population. Poisson regression was used to estimate the association between testing modalities and ART initiation.
Results
Of the 18 397 people included in analyses, 10 627 (58%) were female sex workers (FSWs), 2219 (12%) were men who have sex with men (MSM), and 4970 (27%) were clients of FSWs. HIV case finding varied by modality and population, with index testing and enhanced peer outreach demonstrating high yield despite reaching relatively few individuals. FSWs who tested positive through risk network referral testing were more likely to initiate ART within 30 days compared with those who tested positive through clinic-based testing (adjusted risk ratio [aRR], 1.50; 95% CI, 1.23–1.82). For MSM, index testing (aRR, 1.45; 95% CI, 1.06–2.00) and testing through a drop-in center (aRR, 1.82; 95% CI, 1.19–2.78) were associated with 30-day ART initiation.
Conclusions
These data suggest that differentiated HIV testing and outreach approaches tailored to the needs of different key populations may facilitate improved ART initiation in Malawi. Achieving 0 new infections by 2030 suggests the need to adapt treatment strategies given individual and structural barriers to treatment for key populations with HIV in high-prevalence settings.

The SAARC Member States have more than an estimated 2.0 million TB cases accounting for close to one-third of the total cases of TB in the world. India alone had almost one-fifth of the global disease burden due to TB. India, Pakistan and Bangladesh followed by Afghanistan are the major contributors... of disease burden of TB in the SAARC Region. They are countries that have a dubious distinction of being on the list of 22 TB High Disease Countries in the world.

A Global Analysis of Antimicrobial Resistance and Its Drivers.
Since the first State of the World’s Antibiotics report in 2015, antimicrobial resistance has leveled off in some high-income countries but continues to rise in many low- and middle-income countries (LMICs), where access to antibiotic...s has risen with increases in gross domestic product per capita. Per capita antibiotic consumption in LMICs is lower than in high-income countries, despite a higher infectious disease burden; however, consumption rates are rapidly converging. These trends reflect both better access to antibiotics for those who need them and increases in inappropriate antibiotic use.

For the primary health worker in a low/middle-income country (LMIC) setting, delivering quality primary care is challenging. This is often complicated by clinical guidance that is out of date, inconsistent and informed by evidence from high-income countries that ignores LMIC resource constraints and... burden of disease. The Knowledge Translation Unit (KTU) of the University of Cape Town Lung Institute has developed, implemented and evaluated a health systems intervention in South Africa, and localised it to Botswana, Nigeria, Ethiopia and Brazil, that simplifies and standardises the care delivered by primary health workers while strengthening the system in which they work. At the core of this intervention, called Practical Approach to Care Kit (PACK), is a clinical decision support tool, the PACK guide. This paper describes the development of the guide over an 18-year period and explains the design features that have addressed what the patient, the clinician and the health system need from clinical guidance, and have made it, in the words of a South African primary care nurse, ‘A tool for every day for every patient’. It describes the lessons learnt during the development process that the KTU now applies to further development, maintenance and in-country localisation of the guide: develop clinical decision support in context first, involve local stakeholders in all stages, leverage others’ evidence databases to remain up to date and ensure content development, updating and localisation articulate with implementation.

The incidence of circulatory disorders is increasing worldwide, affecting both low- and middle-income countries and some high-income countries. There is evidence of rising incidence and prevalence rates, even among younger individuals, along with an increasing prevalence of risk factors such as high... blood pressure, diabetes, and obesity. These indicators suggest that current approaches are not

ince the introduction of multidrug therapy (MDT), there has been significant progress in reducing the prevalence of leprosy and the occurrence of new cases. Global strategies have evolved with progress in reducing the disease burden. Encouraged by the decrease in the number of cases on treatment, th...e World Health Assembly passed a resolution calling on Member States to accelerate efforts towards global elimination of leprosy as a public health problem by 2000.
Most countries reached the milestone by 2010. The global strategies for 2006–2015 focused on sustaining high-quality leprosy services and early diagnosis. Reduction in the disease burden was measured in terms of grade-2 disability (G2D) or visible deformities in new cases. Since 2016, the strategies have included reduction of stigmatization of people with leprosy.

The report provides an overview of alcohol consumption, related health harm, and policy responses in 30 European countries (EU Member States, Norway, and Switzerland). It highlights the high levels of alcohol consumption in the WHO European Region, which contribute to a significant disease burden co...mpared to other regions. The report covers trends in alcohol consumption and harm between 2010 and 2016, noting some progress in reducing alcohol-attributable mortality but stagnation in consumption reduction and heavy episodic drinking.
The assessment of alcohol policies shows variability in implementation across countries, particularly in areas like pricing and reducing the negative consequences of drinking. It emphasizes the need for stronger evidence-based policies, such as better regulation, taxation, and accessibility restrictions, to further reduce alcohol-related harm and achieve health-related Sustainable Development Goals.

There is growing international consensus that food systems transformation is important to address the challenges of malnutrition in all its forms, the burden of noncommunicable diseases (NCDs), environmental sustainability, increasing inequality and ensuring the welfare of workers and animals. In li...ght of the urgency of these challenges, there are questions about the role of red and processed meat in healthy and sustainable food systems. Globally, production and consumption of all types of meat has increased substantially in the last 50 years, and – although red meat consumption is now plateauing in high-income countries (HICs) – is predicted to increase by a further 50% by 2050. Meat consumption remains highly unequal both between and within countries, and animal-source food intakes, including red meat, are lowest among those at most risk of undernutrition

Strict storage recommendations for insulin are difficult to follow in hot tropical regions and even more challenging in conflict and humanitarian emergency settings, adding an extra burden to the management of people with diabetes. According to pharmacopeia unopened insulin vials must be stored in a... refrigerator (2–8°C), while storage at ambient temperature (25–30°C) is usually permitted for the 4-week usage period during treatment. In the present work we address a critical question towards improving diabetes care in resource poor settings, namely whether insulin is stable and retains biological activity in tropical temperatures during a 4-week treatment period. To answer this question, temperature fluctuations were measured in Dagahaley refugee camp (Northern Kenya) using log tag recorders. Oscillating temperatures between 25 and 37°C were observed. Insulin heat stability was assessed under these specific temperatures which were precisely reproduced in the laboratory. Different commercialized formulations of insulin were quantified weekly by high performance liquid chromatography and the results showed perfect conformity to pharmacopeia guidelines, thus confirming stability over the assessment period (four weeks). Monitoring the 3D-structure of the tested insulin by circular dichroism confirmed that insulin monomer conformation did not undergo significant modifications. The measure of insulin efficiency on insulin receptor (IR) and Akt phosphorylation in hepatic cells indicated that insulin bioactivity of the samples stored at oscillating temperature during the usage period is identical to that of the samples maintained at 2–8°C. Taken together, these results indicate that insulin can be stored at such oscillating ambient temperatures for the usual four–week period of use. This enables the barrier of cold storage during use to be removed, thereby opening up the perspective for easier management of diabetes in humanitarian contexts and resource poor settings.

The attainment of Zambia’s goal of being a prosperous and middle-income country by 2030 as stipulated in its Vision 2030 is dependent on among others, a healthy and productive population. Therefore, the Government of the Republic of Zambia (GRZ) has prioritized health as a key socio-economic inves...tment in the Seventh National Development Plan 2017-2021. The government is also committed to achieving the targets under the health goal number three and other health related targets under other goals of the 2030 Sustainable Development agenda. Despite progress which has been made in improving the health of Zambians, the country still faces a high burden of communicable diseases and a growing burden of non-communicable diseases. Structural and social deprivation including poverty, inequalities and marginalisation also remain major threats to health. In order to effectively address all the social determinants of health, all sectors should take into account health and well-being as a key element of policy development.

Prior research has considered donor funding for developing world health by recipient and donor country but not by disease. Examining funding by disease is critical since diseases may be in competition with one another for priority and donors may be making allocation decisions in ways that do not cor...respond to developing world need. In this study I calculate donor funding for 20 historically high-burden communicable diseases for the years 1996 to 2003 and examine factors that may explain variance in priority levels among diseases. I consider funding for developing world health from 42 major donors, classifying grants according to the communicable disease targeted. Data show that funding does not correspond closely with burden. Acute respiratory infections comprise more than a quarter of the burden among these diseases but receive less than 3% of direct aid. Malaria also stands out as a high-burden neglected disease.

Antimicrobial resistance (AMR) as a serious public health threat was globally acknowledged by WHO in 2015, through the launch of the Global Action Plan (GAP). With a limited number of new antibiotics in the developmental pipeline, many countries are in the process of establishing strategies for anti...microbial stewardship (AMS). Within each country, different healthcare challenges have
contributed to AMR. This has also shaped individual AMS strategies and policies. In South Africa (SA), there is a high burden of infectious diseases, mainly of bacterial origin. In addition, SA also has the highest number of people living with
human immunodeficiency virus (HIV) globally. According to the 2019 statistics, there are approximately 7.97 million people living with HIV in SA. Together with this, SA has the fourth largest tuberculosis population globally.
Other important challenges include poverty, malnutrition, a high burden of non-communicable diseases, and a dire shortage of trained healthcare professionals (e.g. clinicians, pharmacists, and nurses).

Prevention, early diagnosis, and effective treatment are essential for the control and elimination of Neisseria gonorrhoeae as a public health problem. Currently, in Latin America and the Caribbean, treatment for gonorrhea infection is largely empiric and based on clinical diagnosis. In the Americas..., the high burden of new N. gonorrhoeae infections (estimated at 11 million new cases a year), the complexity of the disease epidemiology, and in many countries the limited resources, make it difficult to fully understand the burden of disease and the burden of antimicrobial resistance (AMR) in N. gonorrhoeae.
PAHO has developed this document to facilitate the navigation of available guidance and recommendations for N. gonorrhoeae AMR surveillance by public health and health care professionals, at the national and subnational levels, involved in designing, implementing, and/or strengthening AMR surveillance of N. gonorrhoeae and overall surveillance of sexually transmitted infections.
