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.

The cardiovascular disease continuum begins with risk factors such as diabetes mellitus (DM), progresses to vasculopathy and myocardial dysfunction, and finally ends with cardiovascular death. Diabetes is associated with a 2- to 4-fold increased risk for heart failure (HF). Moreover, HF patients wit...h DM have a worse prognosis than those without DM. Diabetes can cause myocardial ischemia via micro- and macrovasculopathy and can directly exert deleterious effects on the myocardium. Hyperglycemia, hyperinsulinemia, and insulin resistance can cause alterations in vascular homeostasis. Then, reduced nitric oxide and increased reactive oxygen species levels favor inflammation leading to atherothrombotic progression and myocardial dysfunction. The classification, diagnosis, and treatment of HF for a patient with and without DM remain the same. Until now, drugs targeting neurohumoral and metabolic pathways improved mortality and morbidity in HF with reduced ejection fraction (HFrEF). Therefore, all HFrEF patients should receive guideline-directed medical therapy. By contrast, drugs modulating neurohumoral activity did not improve survival in HF with preserved ejection fraction (HFpEF) patients. Trials investigating whether sodium-glucose cotransporter-2 inhibitors are effective in HFpEF are on-going. This review will summarize the epidemiology, pathophysiology, and treatment of HF in diabetes.

Asthma is the commonest chronic childhood disease and encompasses a spectrum of airway diseases with similar symptoms. Inaccurate diagnosis remains common, especially in younger children, with failure to characterize the different “asthmas.” Children worldwide repeatedly suffer symptoms which se...verely affect their everyday lives. Children die from asthma, especially in low and middle-income countries (LMICs). In many countries, asthma prevalence is rising. Access to effective care and changing environments are hugely variable and may explain the higher morbidity in inner-city children, in LMICs, and in deprived populations in high-income countries. Despite the disease being eminently controllable, morbidity and mortality persist.

Vitamin A deficiency is a risk factor for blindness and for mortality from measles and diarrhoea in children aged 6–59 months. We aimed to estimate trends in the prevalence of vitamin A defi ciency between 1991 and 2013 and its mortality burden in low-income and middle-income countries.
Scabies is a global health concern disproportionately affecting vulnerable populations such as refugees and asylum seekers. Greece is a main point of entry in Europe for refugees, but epidemiological data on scabies in this population are scarce. We aimed to describe the epidemiology of scabies, inc...luding trends over the study period.

Antimicrobial resistance (AMR) is a major public health challenge, which is recognized as high priority area by the Government of India. The increasing consumption of antibiotics is one of the key drivers of antimicrobial resistance seen in bugs of public health importance. Irrational prescription o...f broad-spectrum antibiotics, poor regulations around sale of antibiotics, self-medication, lack of education and awareness regarding responsible use of antibiotics have been identified as some of the key factors driving antimicrobial resistance in our country. The ‘National Health Policy’ (2017), addresses antimicrobial resistance as one of the key issues and prioritises development of guidelines regarding antibiotic use, limiting the over-the-counter use of antibiotics, restricting the use of antibiotics as growth promoters in livestock, and pharmaco-vigilance including prescription audit inclusive of antibiotic usage in the hospital and community.

Cholera is an acute diarrhoeal disease caused by the ingestion of food or water contaminated with the bacterium V.
cholerae. It has a short incubation period of a few hours to 5 days. It is endemic in some countries, frequently
showing seasonal variations in the number of reported cases. Cholera a...lso has the potential to cause explosive
outbreaks which may be localized or may expand to large geographic areas

WHO recommends prompt recognition of progressive acute hypoxaemic respiratory failure when a patient with respiratory distress is failing to respond to standard oxygen therapy and adequate preparation to provide advanced oxygen/ventilatory support.
Hypoxaemic respiratory failure in ARDS commonly re...sults from intrapulmonary ventilation-perfusion mismatch or shunt and usually requires mechanical ventilation.
At any time, if there are urgent or emergent indications for intubation, do not delay.
WHO suggests that hospitalized patients with severe or critical COVID-19 with acute hypoxaemic respiratory failure that do not require emergent intubation be treated with HFNO, or CPAP or NIV (BiPAP) rather than standard oxygen therapy.

Ethnic disparities in COVID-19 persist, with increased rates of infection, severe disease, and death among people from minority ethnic groups. COVID-19 vaccination rates also remain lowest in these communities compared with white people in the UK. Among people older than 18 years, the proportion who... have had three COVID-19 vaccinations in England in March, 2022, was lowest among Black Caribbean (38%), Black African (45%), and Pakistani (45%) ethnic groups. These disparities are likely to be attributed to the intersection of key social determinants, including socioeconomic factors such as deprivation, overcrowding, and working patterns and conditions,
alongside discrimination and structural violence in the health-care system and society.

Updated Treatment Guidelines
Development of one or more vaccines for Neisseria gonorrhoeae is an important objective for sexual and reproductive health worldwide, and for the fight against antimicrobial resistance.
WHO preferred product characteristics (PPCs) provide strategic guidance as to WHO’s preferences for new vacci...nes in priority disease areas. PPCs are intended to encourage innovation and development of vaccines for use in settings most relevant to the global unmet public health need.
Gonococcal vaccine PPCs describe global public health goals for gonococcal vaccines and preferred parameters pertaining to vaccine indications and target populations, safety and efficacy considerations, and immunization strategies.
