How important is ventilation and how does it keep you safe from COVID-19?
Demographic and epidemiological transitions are changing the age structure of the population and the most common diseases. Non-communicable respiratory diseases are an increasing problem at both ends of the age range in low-income and middle-income countries. In children, who represent a large propo...rtion of the total population, the increasing problem of asthma is a strain on health services. Improved survival of the older population is increasing the proportion of morbidity and mortality attributable to chronic lung diseases. Health services in low-resource countries are poorly adapted to treating chronic diseases. Designed to respond episodically to acute disease, almost all historical investment has focused on infectious diseases. Crucial to the successful management of chronic diseases is an infrastructure designed to support pro-active management, providing not only an accurate diagnosis, but also a secure supply of cost effective drugs at an affordable price. The absence of such an infrastructure in many countries and the market failure that makes drugs generally more expensive in low-resource regions means that many people with chronic non-communicable lung diseases are not given effective treatment. This has damaging economic consequences. The common causes of poor lung health in lowincome countries are not the same as those in richer countries, and there is a need to study why they are so common and how best to manage them.

COVID-19 epidemic in Yemen
COVID-19 is thought to be widespread although the actual situation is unclear due to limited reporting and a fear, in Houthi-controlled areas, of seeking medical help. At least 50 people displaying COVID-like symptoms are dying each day. The probability of a high number... of cases, on top of a seasonal rise in endemic diseases, overwhelming the struggling health services, and high mortality has increased to high/very high. Only around three hospitals in each governorate are accepting COVID-19 cases.

The Committee examined the clinical development of Ebola virus vaccines and conducted an inventory of available data on their safety. It also reviewed 3 generic issues: updating a global strategy on vaccine safety, use of a network of distributed data ... to monitor the safety of vaccines and case studies of communication about the safety of human papillomavirus (HPV) vaccines.

Africa is witnessing an epidemic of cardiovascular disease (CVD), with staggering morbidity and mortality. The spectrum of CVD includes hypertension, rheumatic heart disease, cardiomyopathy, atherosclerotic disease, congenital heart disease and tuberculous pericarditis. Opportunities exist to alter ...the trajectory of CVD epidemiology but require committed policy makers, functional health systems and an engaged citizenry.

Two decades of epidemiological research shows that silent cerebrovascular disease is common and is associated with future risk for stroke and dementia. It is the most common incidental finding on brain scans. To summarize evidence on the diagnosis and management of silent cerebrovascular disease to ...prevent stroke, the Stroke Council of the American Heart Association convened a writing committee to evaluate existing evidence, to discuss clinical considerations, and to offer suggestions for future research on stroke prevention in patients with 3 cardinal manifestations of silent cerebrovascular disease: silent brain infarcts, magnetic resonance imaging white matter hyperintensities of presumed vascular origin, and cerebral microbleeds. The writing committee found strong evidence that silent cerebrovascular disease is a common problem of aging and that silent brain infarcts and white matter hyperintensities are associated with future symptomatic stroke risk independently of other vascular risk factors. In patients with cerebral microbleeds, there was evidence of a modestly increased risk of symptomatic intracranial hemorrhage in patients treated with thrombolysis for acute ischemic stroke but little prospective evidence on the risk of symptomatic hemorrhage in patients on anticoagulation. There were no randomized controlled trials targeted specifically to participants with silent cerebrovascular disease to prevent stroke. Primary stroke prevention is indicated in patients with silent brain infarcts, white matter hyperintensities, or microbleeds. Adoption of standard terms and definitions for silent cerebrovascular disease, as provided by prior American Heart Association/American Stroke Association statements and by a consensus group, may facilitate diagnosis and communication of findings from radiologists to clinicians.

Kenya in undergoing an epidemiological transition marked by a decline in morbidity and mortality due to communicable conditions, and an increase in the burden of non-communicable diseases (NCDs), which include diseases such as diabetes, cancers, cardiovascular diseases and chronic respiratory infect...ions. The second strategic objective of KHSSP 2014-2018 targets to halt and reverse the rising burden of non-communicable conditions, while the fifth strategic objective is focused on putting into place health promotion interventions that will address risk factors to health.

The article examines the epidemiology of chronic obstructive pulmonary disease (COPD) in the Middle East, North Africa, and Turkey. It provides an overview of COPD prevalence, associated risk factors, and challenges in diagnosis and treatment across these regions. The study highlights smoking and en...vironmental exposures, such as dust and pollution, as significant contributors to COPD. It also points out the gaps in awareness, healthcare infrastructure, and the availability of diagnostic tools, which hinder effective management of the disease. The authors emphasize the need for comprehensive public health strategies, education, and improved access to healthcare to address the COPD burden in these areas.

The ongoing Ebola epidemic in parts of West Africa largely overwhelmed health-care systems in 2014, making adequate care for malaria impossible and threatening the gains in malaria control achieved over the past decade. The study suggests that untreated malaria cases as a result of reduced health-ca...re capacity probably contributed substantially to the morbidity caused by the Ebola crisis. Mass drug administration can be an effective means to mitigate this burden and reduce the number of non-Ebola fever cases within health systems

The global epidemic of type 2 Diabetes Mellitus (T2DM) presents significant challenges to world health both in terms of financial costs as well as morbidity. Thus, considerable research has been focussed on the prevention or delay of the onset of T2DM.
Type 2 Diabetes Mellitus (T2DM) is one of the ...most costly and burdensome of chronic diseases and is a global epidemic. Estimates by the International Diabetes Federation indicate that 387 million people have diabetes, and that this figure is expected to rise to 592 million by 2035 with an additional 175 million cases currently undiagnosed.

The evolving epidemic of type 2 diabetes mellitus has challenged health-care professionals. It stands among the leading causes of mortality in the present world. It warrants new and versatile approaches to improve mortality and the associated huge quality-adjusted life years lost to it once diagnose...d. A possible venue to lower the incidence is to assess the safety and efficacy of various diabetes prevention strategies. Diet and exercise have a well-developed role in the prevention of weight gain and, ultimately, diabetes mellitus type II in high-risk individuals. However, high-risk individuals can also benefit from adjunct pharmacotherapy. In light of this information, we decided to conduct a systematic review of randomized controlled trials. This article summarizes the evidence in the literature on the pharmacological prevention of diabetes in high-risk individuals.

The dual epidemic of TB and Diabetes
The report discusses the epidemiological and social aspects of ageing, health and functional changes experienced with ageing, the impact of physical activity, assessment of the nutritional status of older persons, and nutritional guidelines for healthy ageing.

Infectious disease epidemics pose a threat to reproductive, maternal, newborn and child health (RMNCH) both directly—by worsening women’s and children’s health outcomes—and indirectly—by reducing their access to services.1–4 Greater investment is therefore needed to mitigate the negative... effects of COVID-19 and avoid a reversal of recent gains in RMNCH coverage and outcomes.1 However, COVID-19 has reduced household and government budgets,5 and there are concerns about the extent to which resources have been diverted away from RMNCH.
