Cardiovascular diseases in Africa in the twenty-first century: Gaps and priorities going forward

Minja, N.W.; Nakagaayi, D.; Aliku, T. et al. Frontiers in Cardiovascular Medicine (2022) CC

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. more

Therapeutics and COVID-19 (Living Guideline, 10 November 2023)

World Health Organization WHO (2023) C_WHO

WHO has updated its guidelines for COVID-19 therapeutics, with revised recommendations for patients with non-severe COVID-19. This is the 13th update to these guidelines. Updated risk rates for hospital admission in patients with non-severe COVID-19 The guidance includes updated risk rates for... hospital admission in patients with non-severe COVID-19. The current COVID-19 virus variants tend to cause less severe disease while immunity levels are higher due to vaccination, leading to lower risks of severe illness and death for most patients. This update includes new baseline risk estimates for hospital admission in patients with non-severe COVID-19. The new ‘moderate risk’ category now includes people previously considered to be high risk including older people and/or those with chronic conditions, disabilities, and comorbidities of chronic disease. The updated risk estimates will assist healthcare professionals to identify individuals at high, moderate or low risk of hospital admission, and to tailor treatment according to WHO guidelines: **High: **People who are immunosuppressed remain at higher risk if they contract COVID-19, with an estimated hospitalization rate of 6%. **Moderate: **People over 65 years old, those with conditions like obesity, diabetes and/or chronic conditions including chronic obstructive pulmonary disease, kidney or liver disease, cancer, people with disabilities and those with comorbidities of chronic disease are at moderate risk, with an estimated hospitalization rate of 3%. Low: Those who are not in the high or moderate risk categories are at low risk of hospitalization (0.5%). Most people are low risk. Review of COVID-19 treatments for people with non-severe COVID-19 WHO continues to strongly recommend nirmatrelvir-ritonavir (also known by its brand name ‘Paxlovid’) for people at high-risk and moderate risk of hospitalization. The recommendations state that nirmatrelvir-ritonavir is considered the best choice for most eligible patients, given its therapeutic benefits, ease of administration and fewer concerns about potential harms. Nirmatrelvir-ritonavir was first recommended by WHO in April 2022. If nirmatrelvir-ritonavir is not available to patients at high-risk of hospitalization, WHO suggests the use of molnupiravir or remdesivir instead. WHO suggests against the use of molnupiravir and remdesivir for patients at moderate risk, judging the potential harms to outweigh the limited benefits in patients at moderate risk of hospital admission. For people at low risk of hospitalization, WHO does not recommend any antiviral therapy. Symptoms like fever and pain can continue to be managed with analgesics like paracetamol. WHO also recommends against use of a new antiviral (VV116) for patients, except in clinical trials. The update also includes a strong recommendation against the use of ivermectin for patients with non-severe COVID-19. WHO continues to advise that in patients with severe or critical COVID-19, ivermectin should only be used in clinical trials. more

OCHA Policy Brief on Gendered Drivers, Risks and Impacts of Food Insecurity in the Sahel and the Horn of Africa

UN Office for the Coordination of Humanitarian Affairs (2023) CC

It is widely understood that the food insecurity crisis in the Sahel and the Horn of Africa is one of the world’s fastest growing and most neglected crises. It lacks sufficient global focus, resources and urgency. As in so many crises, women and girls are disproportionately affected and shoulder t...he consequences of protracted neglect, with unconscionable impacts on their safety, life chances and agency. Gaining a holistic view of the gendered drivers, risks and impacts of food insecurity in the Sahel and the Horn of Africa is difficult. This is due to a lack of data and prioritization, and the large geographical and socioeconomic terrain covered by both regions. However, what we do know about this crisis is more than enough to urgently address the needs of women and girls. An OCHA discussion paper on this topic (which will be published imminently, and from which this policy brief is drawn) found that there is: A strong risk of profound regression in gender equality gains made to date in the countries of concern, including on education, sexual and reproductive health, and the economic independence of women and girls (with knock-on effects on broader humanitarian and development outcomes). An increasing challenge to reverse what must be recognized as a protracted and growing gender-based violence (GBV) emergency in the Sahel and the Horn of Africa. The food insecurity crisis in the Sahel and the Horn of Africa is protracted, multidimensional and highly gendered, with spiralling impacts on gender equality and food security outcomes. It is driven by interwoven and overlapping factors, including climate change, political instability, conflict, socioeconomic conditions, migration and displacement and, more recently, COVID-19 and the war in Ukraine. Interlinked with these factors are gendered structural drivers of food insecurity, including deeply entrenched gender inequalities and harmful social norms. Gendered risks and impacts of food insecurity include alarming limitations on access to education, sexual and reproductive health rights, women’s agency and participation, and dramatic increases in different existing forms of GBV and the emergence of new ones. Recognition of such gendered dimensions of food insecurity and of the need for a multisectoral approach in the response is key to addressing the crisis, along-side sustained commitment and adequate allocation of resources. This policy brief draws out key findings from the OCHA discussion paper on this topic, which includes a desk review of studies, assessments and reports, and interviews with local women’s organizations on the front lines of the food insecurity crisis in communities across both regions. Below are the most pressing gendered drivers, risks and impacts of food insecurity (not in order of priority), as well as key gaps in the current humanitarian response to food insecurity, and recommendations to take forward. more
