Atherosclerotic lower-extremity peripheral artery disease (PAD) is increasingly recognized as an important cause of cardiovascular morbidity and mortality that affects more than 230 million people worldwide. Traditional cardiovascular risk factors, including advanced age, smoking, and diabetes, are ...strongly linked to an increase risk of PAD. Although PAD has been historically underappreciated compared to coronary artery disease and stroke, greater attention on PAD in recent years has led to important new epidemiologic insights in the areas of thrombosis, inflammation, dyslipidemia, and microvascular disease. In addition, the concept of polyvascular disease, or clinically-evident atherosclerosis in multiple arterial beds, is increasingly identified as a particularly malignant cardiovascular disease worthy of special clinical attention and further study. It is noteworthy that PAD may increase the risk of adverse outcomes in similar or even greater magnitude than coronary disease or stroke. In this review, we highlight important new advances in the epidemiology of PAD with a particular focus on polyvascular disease, emerging biomarkers, and differential risk pathways for PAD compared to other atherosclerotic diseases.

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.

Alcohol consumption is deeply embedded in the social landscape of many societies. Several major factors have an impact on levels and patterns of alcohol consumption in populations – such as historical trends in alcohol consumption, the availability of alcohol, culture, economic status and trends i...n the marketing of alcoholic beverages, as well as implemented alcohol control measures. At the individual level, the patterns and levels of alcohol consumption are determined by many different factors, including gender, age and individual biological and socioeconomic vulnerability factors, as well as the policy environment. Prevailing social norms that support drinking behaviour and mixed messages about the harms and benefits of drinking encourage alcohol consumption delay appropriate health-seeking behaviour and weaken community action

Hurricane Matthew has displaced around 175,500 people. Serious protection concerns in these shelters put at risk some highly vulnerable people due to their age, gender, disability, sexual orientation, or a combination of factors. Separated and unaccompanied children, single mothers or single-headed ...households, pregnant or lactating women and girls, families at risk of separation, and people with chronic illnesses have also been identified. Psychosocial distress and lack of privacy, electricity, water, sanitation and hygiene create a situation in which girls and boys face exploitation, abuse, aggression, and sexual and gender based violence.

The article "Barriers and determinants of asthma control in children and adolescents in Africa: a systematic review" analyzes factors contributing to poor asthma control in African youth. Based on studies conducted between 2014 and 2019 in Nigeria, Uganda, and South Africa, the review identifies key... challenges such as limited access to asthma diagnosis, inadequate use of inhaled corticosteroids, and environmental and socio-economic factors. It finds that urban living, older age, and concurrent allergic conditions significantly affect asthma management. The study emphasizes the need for improved diagnostic tools, better access to treatment, and tailored public health interventions to enhance asthma outcomes in African children.

Hypertension, or high blood pressure, is a condition which generally has no symptoms and if left untreated, can lead to heart attacks, heart failure, stroke, kidney failure and blindness. Risk factors include older age, overweight or obesity, lack of physical activity, high salt/sodium intake, and h...igh alcohol intake.
Hypertension affects around 1 in 6 adults in the Americas and is the main risk factor for cardiovascular diseases, which are the leading cause of death in the region, responsible for around 2 million lives lost each year.

Type 2 diabetes mellitus (T2DM) is a chronic condition characterized by insulin resistance and an inability to properly regulate blood sugar levels. The two most important risk factors for T2DM are a family history of diabetes and obesity, though age, race, diet, and exercise level also impact risk.... Common symptoms include frequent urination, nerve damage, and dark skin patches. Treatment involves lifestyle changes like diet and exercise as well as medications like metformin, which improves insulin sensitivity and decreases glucose production in the liver. Patients are counseled on managing diabetes-related risks and provided support through organizations and groups.

This study is a theory-driven analysis of the socio-demographic determinants of maternal care seeking in Kenya. Specifically, it examines predisposing, enabling, and need factors potentially associated with use of antenatal care (ANC), health facility delivery, and timely postnatal care (PNC).This s...tudy uses data from the 2014 Kenya Demographic and Health Survey (KDHS) conducted among women age 15-49 with a live birth in the five years preceding the survey. It includes data from all 47 counties of Kenya, grouped contiguously into 12regions.We apply Andersen’s Behavioral Model of Health Services Use to examine socio-demographic predictors of health service use.We estimate logistic regression models for adequate use of ANC (defined as attending at least four ANC visits, starting in the first three months of pregnancy), delivery in a health facility, and PNC within 48 hours of delivery.

The report showed commitments made three decades ago to protect the rights of children remain unfulfilled for millions. Violence still affects countless children. Discrimination based on age, gender, disability, sexual orientation and religion harms children worldwide.
Key factors include a lack ...of investment in critically important services. Most countries fall well short of spending the 5-6% of GDP needed to ensure universal coverage of essential health care. And foreign aid, which many lower income countries rely on, is falling short in areas such as health, education, protection and child care.
Another factor, the report said, is the lack of quality data. Governments tend to rely on data that reflects national averages, making it difficult to identify the needs of specific children and to monitor progress. Comprehensive data collection and disaggregation of data by gender, age, disability and locality, are increasingly important as rights violations disproportionately affect disadvantaged children.

The article "Under- and over-diagnosis of COPD: a global perspective" reviews the worldwide variation in the prevalence of chronic obstructive pulmonary disease (COPD) and issues related to its misdiagnosis. It highlights that COPD is under-diagnosed due to factors such as limited access to spiromet...ry and variable diagnostic criteria, especially in low- and middle-income countries. Conversely, over-diagnosis often results from reliance on non-standard criteria or inadequate spirometry use. The article discusses key risk factors, including age, gender, exposure to pollutants, and comorbidities, and emphasizes the need for standardized diagnostic practices to better address and manage COPD globally.

In the spirit of the Sustainable Development Goals, WHO and the International Labour Organization (ILO) produce the WHO/ILO Joint Estimates of the Work-related Burden of Disease and Injury (WHO/ILO Joint Estimates). The WHO/ILO Joint Estimates quantify the population exposed to occupational risk fac...tors and amount health loss caused by these exposures. Global, regional and national estimates are produced of the numbers of deaths and disability-adjusted life years that can be attributed to exposure to selected occupational risk factors. Estimates are produced disaggregated by sex and age group.

In 2015, the United Nations set important targets to reduce premature
cardiovascular disease (CVD) deaths by 33% by 2030. Africa disproportionately
bears the brunt of CVD burden and has one of the highest risks of dying
from non-communicable diseases (NCDs) worldwide. There is currently
an epide...miological transition on the continent, where NCDs is projected
to outpace communicable diseases within the current decade. Unchecked
increases in CVD risk factors have contributed to the growing burden of three
major CVDs—hypertension, cardiomyopathies, and atherosclerotic diseasesleading to devastating rates of stroke and heart failure. The highest age
standardized disability-adjusted life years (DALYs) due to hypertensive heart
disease (HHD) were recorded in Africa. The contributory causes of heart failure
are changing—whilst HHD and cardiomyopathies still dominate, ischemic
heart disease is rapidly becoming a significant contributor, whilst rheumatic
heart disease (RHD) has shown a gradual decline. In a continent where health
systems are traditionally geared toward addressing communicable diseases,
several gaps exist to adequately meet the growing demand imposed by CVDs.
Among these, high-quality research to inform interventions, underfunded
health systems with high out-of-pocket costs, limited accessibility and
affordability of essential medicines, CVD preventive services, and skill
shortages. Overall, the African continent progress toward a third reduction
in premature mortality come 2030 is lagging behind. More can be done in
the arena of effective policy implementation for risk factor reduction and
CVD prevention, increasing health financing and focusing on strengthening
primary health care services for prevention and treatment of CVDs, whilst
ensuring availability and affordability of quality medicines. Further, investing
in systematic country data collection and research outputs will improve the accuracy of the burden of disease data and inform policy adoption on
interventions. This review summarizes the current CVD burden, important
gaps in cardiovascular medicine in Africa, and further highlights priority
areas where efforts could be intensified in the next decade with potential
to improve the current rate of progress toward achieving a 33% reduction
in CVD mortality.

Background: Healthcare workers’ mental health was affected by SARS-CoV-2 pandemic.
Aim: To evaluate healthcare workers’ mental health and its associated factors during the pandemic in Chile. Material and Methods: An online self-reported questionnaire was designed including the Goldberg Healt...h Questionnaire, the Patient Health
Questionnaire, (PHQ-9), and the Columbia-Suicide Severity Rating Scale among other questions. It was sent to 28,038 healthcare workers.
Results: The questionnaire was answered by 1,934 participants, with a median age of 38 years (74% women). Seventy five percent were professionals, and 48% worked at a hospital. Fifty nine percent of respondents had a risk of having a mental health disorder, and 73% had depressive symptoms. Significant associations were found with sex, workplace, and some of the relevant experiences during the pandemic. Fifty one
percent reported the need for mental health support, and 38% of them received it.
Conclusions: There is a high percentage of health workers with symptoms of psychological distress, depression, and suicidal ideas. The gender approach is essential to understand the important differences found. Many health workers who required mental health care did not seek or received it.

The Defeat-NCD Partnership prioritises poorer countries because they bear the brunt of the enormous impact of NCDs with some 48% of premature deaths occurring in low and lower-middle income countries. The resident of a low-income country faces a lifetime chance of 20-30% of dying from an NCD under t...he age of 70; this is two-to-four-fold higher than the equivalent risk for a high-income country resident. Meanwhile, when poor countries start getting a little more prosperous, the prevalence of NCD risk factors tend to initially increase.

COVID-19 Vaccines: 1 Safety Surveillance 2 Manual
While there is no indication that pregnant women have an increased susceptibility to infection with SARS-CoV-2, there is evidence that pregnancy may increase the risk of severe illness and mortality from COVID-19 disease in comparison with non-pregn...ant women of reproductive age. As seen with non-pregnant women, a high proportion of pregnant women have asymptomatic SARS-CoV-2 infection and severe disease is associated with recognized medical (e.g., high body-mass index (BMI), diabetes, pre-existing pulmonary or cardiac conditions) and social (e.g., social deprivation, ethnicity) risk factors. Pregnant women with symptomatic COVID-19 appear to have an increased risk of intensive care unit admission, mechanical ventilation and death in comparison with non-pregnant women of reproductive age, although the absolute risks remain low. COVID-19 may increase the risk of preterm birth, compared with pregnant women without COVID-19, although the evidence is inconclusive.

High blood pressure, or hypertension, is one of the most serious risks factors for death from heart diseases and strokes, responsible for 13% of all deaths globally. In South Africa more than 1 in 3 adults live with high blood pressure and it is responsible for 1 in every 2 strokes and 2 in every 5 ...heart attacks. High blood pressure is known as a 'silent killer' because there are rarely any symptoms or visible signs to warn that blood pressure is high. That is why more than 50% of people with high blood pressure are unaware of their condition. In some cases, typically with very high blood pressure, symptoms such as headaches, visual disturbances, nose bleeds, nausea, vomiting, facial flushing and sleepiness may be experienced. Do not wait for symptoms to appear. High blood pressure becomes more likely with older age, but anyone, no matter their age, gender, fitness level or lifestyle can develop high blood pressure. Blood pressure should be measured at least once every year, so don’t delay!

Cardiovascular disease is a major cause of disability and premature death throughout the world, and contributes substantially to the escalating costs of health care. The underlying pathology is atherosclerosis, which develops over many years and is usually advanced by the time symptoms occur, genera...lly in middle age. Acute coronary and cerebrovascular events frequently occur suddenly, and are often fatal before medical care can be given. Modification of risk factors has been shown to reduce mortality and morbidity in people with diagnosed or undiagnosed cardiovascular disease.
This publication provides guidance on reducing disability and premature deaths from coronary heart disease, cerebrovascular disease and peripheral vascular disease in people at high risk, who have not yet experienced a cardiovascular event. People with established cardiovascular disease are at very high risk of recurrent events and are not the subject of these guidelines. They have been addressed in previous WHO guidelines.
Several forms of therapy can prevent coronary, cerebral and peripheral vascular events. Decisions about whether to initiate specific preventive action, and with what degree of intensity, should be guided by estimation of the risk of any such vascular event. The risk prediction charts that accompany these guidelinesb allow treatment to be targeted accord-
ing to simple predictions of absolute cardiovascular risk.
Recommendations are made for management of major cardiovascular risk factors through changes in lifestyle and prophylactic drug therapies. The guidelines provide a framework for the development of national guidance on prevention of cardiovascular disease that takes into account the particular political, economic, social and medical circumstances.
