Heart failure with a reduced ejection fraction (HFrEF) is a condition frequently encountered by healthcare professionals and, in order to achieve the best outcomes for patients, needs to be managed optimally. This guideline document is based on the European Society of Cardiology Guidelines for the t...reatment of acute and chronic heart failure published in 2016, and summarises what is considered the best current management of patients with the condition. It provides information on the definition, diagnosis and epidemiology of HFrEF in the African context. The best evidence-based treatments for HFrEF are discussed, including established therapies (beta-blockers, ACE-i/ARBs, mineralocorticoid receptor antagonists (MRAs), diuretics) that form the cornerstone of heart failure management as well as therapies that have only recently entered clinical use (angiotensin receptor-neprilysin inhibitor (ARNI), sodium/glucose cotransporter-2 (SGLT2) inhibitors). Guidance is offered in terms of more invasive therapies (revascularisation, implantable cardioverter defibrillators (ICDs) and cardiac resynchronisation therapy (CRT) by implantation of a biventricular pacemaker with (CRT-D) or without (CRT-P) an ICD, left ventricular assist device (LVAD) use and heart transplantation) in order to ensure efficient use of these expensive treatment modalities in a resourcelimited environment. Furthermore, additional therapies (digoxin, hydralazine and nitrates, ivabradine, iron supplementation) are discussed and advice is provided on general preventive strategies (vaccinations). Sections to discuss conditions that are particularly prevalent in sub-Saharan Africa (HIV-associated cardiomyopathy (CMO), peripartum CMO, rheumatic heart disease, atrial fibrillation) have been added to further improve clinical care for these commonly encountered disease processes.

Background
Chronic congestive heart failure is a common condition that, if untreated, markedly impairs the quality of life and is associated with a high risk of recurrent hospitalization and death.
Methods
This review is based on articles retrieved by a selective search in PubMed, as well as on r...elevant guidelines.
Results
Evidence-based treatment options are available only for congestive heart failure with a low ejection fraction. Pharmacotherapy is based on neurohumoral inhibition of the renin-angiotensin-aldosterone system and the adrenergic system. The prognosis of patients with this condition has been further improved recently through the introduction of combined angiotensin receptor antagonists and neprilysin inhibitors. Modern implantable devices are a further component of treatment. Implantable defibrillators and special pacemakers for cardiac resynchronization are well established; the utility of alternative devices (baroreflex modulation or cardiac contractility modulation) needs to be investigated in further studies. It was recently shown that the catheter-based treatment of secondary mitral regurgitation with a MitraClip improves the outcome of selected patients.
Conclusion
The treatment of chronic systolic heart failure as recommended in the relevant guidelines, with drugs and implanted devices if indicated, can significantly improve the clinical outcome.

Many features of the environment have been found to exert an important influence on cardiovascular disease (CVD) risk, progression, and severity. Changes in the environment due to migration to different geographic locations, modifications in lifestyle choices, and shifts in social policies and cultu...ral practices alter CVD risk, even in the absence of genetic changes. Nevertheless, the cumulative impact of the environment on CVD risk has been difficult to assess
and the mechanisms by which some environment factors influence CVD remain obscure. Human environments are complex; and their natural, social and personal domains are highly variable due to diversity in human ecosystems, evolutionary histories, social structures, and individual choices. Accumulating evidence supports the notion that ecological features such as the diurnal cycles of
light and day, sunlight exposure, seasons, and geographic characteristics of the natural environment such altitude, latitude and greenspaces are important determinants of cardiovascular health and CVD risk. In highly developed societies, the influence of the natural environment is moderated by the physical characteristics of the social environments such as the built environment
and pollution, as well as by socioeconomic status and social networks. These attributes of the
social environment shape lifestyle choices that significantly modify CVD risk. An understanding
of how different domains of the environment, individually and collectively, affect CVD risk could
lead to a better appraisal of CVD, and aid in the development of new preventive and therapeutic
strategies to limit the increasingly high global burden of heart disease and stroke.

The burden of diabetes is enormous, positioning it as one of the main challenges facing public health today. Currently, it is estimated that 62 million people are living with diabetes in the Region of the Americas and projections show its prevalence will continue rising over the following years. The... Region shows the highest number of years of healthy life lost (through either disability or premature death) due to diabetes worldwide. The high costs associated with its treatment produce a heavy economic burden. Its complications can seriously affect the quality of life of people living with diabetes, their families, and society and overload health systems. This report shows the latest internationally comparable data on diabetes and its main risk factors by year, country, and sex. It also includes a summary of the countries health systems’ response to diabetes, including national plans, targets, surveillance, guidelines, and access to essential drugs and technologies, and synthesizes information about diabetes-related complications and the close relationship between diabetes and other pathologies, such as cardiovascular diseases, tuberculosis, and COVID-19. The data presented here reveal that, despite advances in national responses, diabetes continues to expand, and our response remains insufficient. This report aims to draw attention to the urgent need to strengthen efforts to prevent, diagnose, and control diabetes in the Region of the Americas.

Diabetes is a significant public health issue that affects approximately one in 10 adults globally, with type 2 diabetes accounting for 90–95% of cases. This chronic condition causes considerable morbidity and mortality and is growing in impact, with cases projected to rise from 537 million in 202...1 to 784 million by 2045.1 As cases rise, it is imperative to ensure the healthcare workforce is prepared to care for affected individuals. However, there is a growing global shortage of healthcare workers, which was estimated, pre pandemic, to reach 15 million by 2030.2 Therefore, all of the healthcare workforce will need to be utilised to their fullest potential in order to address the growing global burden of diabetes. Pharmacists will continue to be essential in this endeavour.

Patients with diabetes are at increased risk of developing cardiovascular disease (CVD) with its manifestations of coronary artery disease (CAD), heart failure (HF), atrial fibrillation (AF), and stroke, as well as aortic and peripheral artery diseases. In addition, diabetes is a major risk factor f...or developing chronic kidney disease (CKD), which in itself is associated with developing CVD. The combination of diabetes with these cardio-renal comorbidities enhances the risk not only for cardiovascular (CV) events but also for CV and all-cause mortality. The current European Society of Cardiology (ESC) Guidelines on the management of cardiovascular disease in patients with diabetes are designed to guide prevention and management of the manifestations of CVD in patients with diabetes based on data published until end of January 2023. Over the last decade, the results of various large cardiovascular outcome trials (CVOTs) in patients with diabetes at high CV risk with novel glucose- lowering agents, such as sodium–glucose co-transporter-2 (SGLT2) inhibitors and glucagon-like peptide-1 (GLP-1) receptor agonists (RAs), but also novel non-steroidal mineralocorticoid receptor antagonists (MRAs), such as finerenone have substantially expanded available therapeutic op-
tions, leading to numerous evidence-based recommendations for the management of this patient population.

Mpox continues to affect people around the world. A new framework released today by WHO will guide health authorities, communities and other stakeholders in preventing and controlling mpox outbreaks, eliminating human-to-human transmission of the disease, and reducing spillover of the virus from ani...mals to humans.
Mpox is a viral illness caused by the monkeypox virus (MPXV). It can cause a painful rash, enlarged lymph nodes and fever. Most people fully recover, but some get very sick. The virus transmits from person to person through close, including sexual, contact. It also has animal reservoirs in east, central and west Africa, where spillovers from animals to humans can occasionally occur, sparking further outbreaks.
There are two different clades of the virus: clade I and clade II. Clade I outbreaks are deadlier than clade II outbreaks.
A major emergence of mpox linked to clade II began in 2017, and since 2022, has spread to all regions of the world. Between July 2022 and May 2023, the outbreak was declared a Public Health Emergency of International Concern. While that outbreak has largely subsided, cases and deaths continue to be reported today, illustrating that low-level transmission continues around the world.
Currently, there is also a major outbreak of clade I virus in the Democratic Republic of the Congo (DRC), where cases have been on the rise for decades. Since the beginning of the year, over 6500 cases and 345 deaths have been reported in the DRC. Almost half of these are among children under the age of 15 years.
The Strategic framework for enhancing prevention and control of mpox (2024–2027) provides a roadmap for health authorities, communities, and stakeholders worldwide to control mpox outbreaks in every context, advance mpox research and access to countermeasures, and to minimize zoonotic transmission.

Non-Communicable Diseases (NCDs), including mental disorders, currently pose one of the biggest threats to health and development globally, particularly in low and middle income countries2. It is predicted that unless proven interventions are rapidly implemented in countries, in the short to medium ...term, health care costs will increase exponentially and severe negative consequences will ensue not only to individuals and families but to whole societies and economies. NCDs are already a major burden in South Africa, but without added rigorous and timely action the health and development consequences may well become catastrophic. Immediate and additional, high quality, evidence based and focussed interventions are needed to promote health, prevent disease and provide more effective and equitable care and treatment for people living with NCDs at all levels of the health system. The problem is further compounded by the rising global prevalence of multi-morbidity (defined as the coexistence of two or more chronic diseases in one individual).

There is paucity of data on the burden and specific drivers operative in the pathogenesis of chronic obstructive pulmonary disease (COPD) in the African setting and populations. Lack of awareness and inadequate knowledge on the aetio-pathogenesis of the disease together with inadequate capacity for ...COPD care contributes to preventive and management challenges. Thus, the majority of patients with COPD are misdiagnosed, misclassified and mismanaged or undertreated. With the struggling improvement in the quality of healthcare in Africa, studies conducted over the last 10 years indicates the rising trends in both the risk factors and the burden of COPD. The role of new risk factors such as indoor pollution, infections with human immunodeficiency virus (HIV) and pulmonary tuberculosis (TB), in the pathogenesis of COPD in Africa is increasingly being recognized. This literature review attempts to collect and synthesize information that could be useful in improving COPD care and informing the governments to take appropriate actions for prevention, diagnosis and management of COPD in Africa.

Fragile health systems are further stressed as health workers navigate an increased client load and demands at work while also being concerned for their own health and ...that of their families. Health facilities have been redesigned to care for patients with COVID-19, posing challenges to other services. Governments and civil society organizations have redirected scarce resources and shifted programming priorities to respond to the pandemic. Several countries have reported intermittent declines in HIV testing and diagnosis, antenatal care visits, collection of antiretroviral medicines (ARVs) by people living with HIV, and attendance at clinic appointments. Community-based education and support programmes have had to rapidly adapt to restrictions on movement and public gatherings. Children, adolescents, and women have experienced multiple deprivations due to the adverse impact of the pandemic.
