The article provides a systematic review and meta-analysis of the prevalence and risk factors of chronic obstructive pulmonary disease (COPD) in sub-Saharan Africa (SSA). It highlights that COPD is a significant cause of morbidity and mortality in the region, with prevalence rates ranging from 1.7% ...to 24.8% and an average pooled prevalence of 8%. The analysis points out that smoking, exposure to biomass smoke, and age are key risk factors. The study emphasizes the need for improved diagnosis and awareness, as COPD often remains underdiagnosed and undertreated in SSA. The authors call for coordinated efforts from clinicians, researchers, and policymakers to address these issues and reduce exposure to preventable risk factors.

This study investigated occupational risk factors and exposure–response relationships for airway disease among health workers (HWs) exposed to cleaning agents in two tertiary hospitals in South Africa and Tanzania.
Previous studies have demonstrated an association between asthma or respiratory... symptoms and exposure to broad categories of cleaning-related exposures in healthcare settings. However, few studies have identified the specific cleaning agents responsible for asthma and other health outcomes. Products used for medical instrument cleaning and disinfection such as glutaraldehyde, orthophthalaldehyde (OPA) and quaternary ammonium compounds (QACs) have been implicated in the causation and exacerbation of work-related asthma (WRA) and upper airway outcomes such as rhinitis.

Background
In the prevention of cardiovascular disease, a WHO target is that at least 50% of eligible people use statins. Robust evidence is needed to monitor progress towards this target in low-income and middle-income countries (LMICs), where most cardiovascular disease deaths occur. The objectiv...es of this study were to benchmark statin use in LMICs and to investigate country-level and individual-level characteristics associated with statin use.

Development of cardiovascular disease (CVD) is influenced by risk factors such as:
tobacco use, an unhealthy diet, physical inactivity, obesity (which can result from
a combination of unhealthy diet, physical inactivity, and other factors), elevated
blood pressure (hypertension), abnormal blood l...ipids (dyslipidaemia) and elevated blood glucose (diabetes mellitus). Continuing exposure to these risk factors leads
to further progression of atherosclerosis, resulting in clinical manifestations of these diseases, including angina pectoris, myocardial infarction, heart failure and stroke. Total CVD risk depends on the individual’s overall risk-factor profile.

This short brief describes the main findings and the key lessons learned from the research project "Evaluation of the impact of alcohol control policies on morbidity and mortality in Lithuania and other Baltic states", funded by the United States National Institute on Alcohol Abuse and Alcoholism fo...r the period 2000–2025. The WHO-backed project aims to assess the effects of alcohol control policies implemented in Estonia, Latvia and Lithuania and to investigate the impact they have had on both people's health and the countries' economies, based on concrete actions taken. The key findings of the project demonstrate that alcohol control policies such as taxation and availability measures decrease all-cause mortality and reduce inequalities, and that dismantling alcohol control policies has the opposite effect on population health. They also highlight that consumption of unrecorded alcohol will not necessarily go up if taxation is increased and that specific countermeasures can be taken to prevent an increase in unrecorded consumption.

Peripheral artery disease (PAD) is a disease of the blood vessels outside the heart and brain. PAD often occurs due to a buildup of fatty deposits in the arteries.
PAHO has developed a series of country profiles on diabetes that illustrate the growing burden of diabetes and diabetic kidney disease in countries in the Region of the Americas. The country profiles reveal that over the past 20 years, diabetes disability (excluding diabetic kidney disease) increase...d in all countries in the Region, in both men and women, while diabetic kidney disease increased in 31 of the countries. 33 countries analyzed.

Background: Peripheral artery disease is a growing public health problem. We aimed to estimate the global disease burden of peripheral artery disease, its risk factors, and temporospatial trends to inform policy and public measures.
Methods: Data on peripheral artery disease were modelled using the... Global Burden of Disease, Injuries, and Risk Factors Study (GBD) 2019 database. Prevalence, disability-adjusted life years (DALYs), and mortality estimates of peripheral artery disease were extracted from GBD 2019. Total DALYs and age-standardised DALY rate of peripheral artery disease attributed to modifiable risk factors were also assessed.

Peripheral artery disease is similar to coronary artery disease (CAD).
Peripheral artery disease is a narrowing of the peripheral arteries that carry blood away from the heart to other parts of the body. The most common type is lower-extremity PAD, in which blood flow is reduced to the legs and fee...t. Upper-extremity PAD (arms, hands and fingers) is less common but affects about 10% of the population.
Both PAD and coronary artery disease are caused by atherosclerosis, the buildup of fatty plaque in the arteries that narrows and blocks them throughout the body, including in the heart, brain, arms, legs, pelvis and kidneys.

Disease burden is measured in Disability-Adjusted Life Years (DALYs) – both from years of life lost due to premature death and years lived witha disability. One DALY equals one year of healthy life.
The risk factors for CVD include behavioural factors, such as tobacco use, an unhealthy diet, harmful use of alcohol and inadequate physical activity, and physiological (metabolic) factors, including high blood pressure (hypertension), high blood cholesterol and high blood sugar or glucose. Both kin...ds of factor are linked to underlying social determinants and drivers. This module focuses on the behavioural risk factors and provides information on: • tobacco use, unhealthy diet, insufficient physical activity and harmful use of alcohol as important contributors to CVDs • behavioural change, brief interventions for counselling and key points for motivational interviewing • the theory of the 5As for brief interventions, as well as sample brief interventions for each risk factor, using the 5As. Target users of this module This module is intended for trainers of primary health care workers, including physicians, nurses, and other health workers. Primary care workers should be trained on the risk factors and counselling approaches, adapting to local customs, culture and context. NCD programme managers may also use it for planning purposes.

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.

Background: Data on burden of peripheral artery disease (PAD) and its attributable risk factors are valuable for policymaking. We aimed to estimate the burden and risk factors for PAD from 1990 to 2019.
Methods: We extracted the data on prevalence, incidence, death, years lived with disability (YLD...s), and years of life lost (YLLs) from the Global Burden of Disease Study 2019 to measure PAD burden. Moreover, the attributable burden to PAD risk factors was also estimated.
Results: Globally, in 2019, 113,443,017 people lived with PAD and 10,504,092 new cases occurred, resulting in 74,063 deaths, 500,893 YLDs, and 1,035,487 YLLs. The absolute numbers of PAD prevalent and incident cases significantly increased between 1990 and 2019, contrasting with the decline trends in age-standardized prevalence and incidence rates. However, no statistically significant changes were detected in the global age-standardized death or YLL rates. The burden of PAD and its temporal trends varied significantly by location, gender, age group, and social-demographic status. Among all potentially modifiable risk factors, age-standardized PAD deaths worldwide were primarily attributable to high fasting plasma glucose, followed by high systolic blood pressure, tobacco, kidney dysfunction, diet high in sodium, and lead exposure.
Conclusion: PAD remained a serious public health problem worldwide. More strategies aimed at implementing cost-effective interventions and addressing modifiable risk factors should be carried out, especially in regions with high or increasing burden.
