Buruli ulcer caused by Mycobacterium ulcerans is a neglected tropical disease characterized by extensive ulceration involving predominantly the upper and lower limbs of patients. The disease is common in rural tropical communities in West and Central Africa, where access to proper health care is lim...ited. Pathogenesis of the characteristic painless ulcers is linked to the elaboration by M. ulcerans of a lipid toxin called mycolactone that has potent cytopathic, immunosuppressive, and analgesic effects on a host of cells in cutaneous tissues. Mycolactone is known to profoundly inhibit secretion of a plethora of proteins that are essential for wound healing. Even though a combination antibacterial therapy of streptomycin and rifampicin for 8 weeks is effective for treatment, it relies on good and appropriate wound management to prevent secondary bacterial infections and improve healing. Evidence-based interventions for wound care in Buruli ulcer disease are often lacking and have relied on expert advice and recommendations. Surgical interventions are limited to debridement of necrotic tissue and grafting of extensive ulcers, usually after antibiotic therapy. Patients’ rehabilitation is an important component of care to reduce disabilities associated with the disease and proper integration into the community after treatment.

Nat Commun 9, 5370 (2018). https://doi.org/10.1038/s41467-018-07804-8. Mycobacterium ulcerans is the causative agent of Buruli ulcer, a neglected tropical skin disease that is most commonly found in children from West and Central Africa. Despite the severity of the infection, therapeutic options are... limited to antibiotics with severe side effects. Here, we show that M. ulcerans is susceptible to the anti-tubercular drug Q203 and related compounds targeting the respiratory cytochrome bc1:aa3. While the cytochrome bc1:aa3 is the primary terminal oxidase in Mycobacterium tuberculosis, the presence of an alternate bd-type terminal oxidase limits the bactericidal and sterilizing potency of Q203 against this bacterium. M. ulcerans strains found in Buruli ulcer patients from Africa and Australia lost all alternate terminal electron acceptors and rely exclusively on the cytochrome bc1:aa3 to respire. As a result, Q203 is bactericidal at low dose against M. ulcerans replicating in vitro and in mice, making the drug a promising candidate for Buruli ulcer treatment.

Diabetes mellitus, commonly known as diabetes, is a group of metabolic disorders characterized by the presence of hyperglycaemia in the absence of treatment. The heterogeneous aetiopathology includes defects in insulin secretion, insulin action, or both. The long-term specific complications of diabe...tes include retinopathy, nephropathy, and neuropathy. People with diabetes are also at increased risk of other diseases, including cardiac, peripheral arterial and cerebrovascular disease, cataracts, erectile dysfunction, and nonalcoholic fatty liver disease. They are also at an increased risk of some infectious diseases such as tuberculosis, and are likely to experience poorer outcomes.

Cystic fibrosis (CF) was earlier thought to be a disease prevalent in the West among Caucasians. However, quite a number of recent studies have uncovered CF cases outside of this region, and reported hundreds of unique and novel variant forms of CFTR. Here, we discuss the evidence of CF in parts of... the world earlier considered to be rare; Africa, and Asia. This review also highlighted the CFTR mutation variations and new mutations discovered in these regions. This discovery implies that the CF data from these regions were earlier underestimated. The inadequate awareness of the disease in these regions might have contributed towards the poor diagnostic facilities, under-diagnosis or/and under-reporting, and the lack of CF associated health policies. Overall, these regions have a high rate of infant, childhood and early adulthood mortality due to CF. Therefore, there is a need for a thorough investigation of CF prevalence and to identify unique and novel variant mutations within these regions in order to formulate intervention plans, create awareness, develop mutation specific screening kits and therapies to keep CF mortality at bay.

This purpose of this guide is to inform robust evaluations of the WHO training package – a package aimed at personnel whose primary role in health-care facilities is environmental cleaning, hereafter referred to as cleaners.
The WHO training package – Environmental cleaning and infection prev...ention and control in health-care facilities in low- and middle-income countries – was designed to improve the competencies of cleaners through a practical, educational approach for adult learners in low- and middle-income countries and comprises two volumes: trainer’s guide and modules and resources (1,2). An associated OpenWHO online course describes the essential preparations for trainers to deliver the WHO training package.

Most of the global burden of sepsis occurs in low- and middle-income countries (LMICs), but the prevalence and etiology of sepsis in LMICs are not well understood. In particular, the lack of laboratory infrastructure in many LMICs has historically precluded an assessment of the pathogens leading to ...sepsis. A recent systematic review found that data describing antimicrobial resistance were absent for 43% of countries in Africa, and only two countries have national antimicrobial resistance plans. In addition, small studies have identified indiscriminate antibiotic use both in and out of hospital settings in sub-Saharan Africa. The absence of microbiological data and lack of antibiotic stewardship complicate sepsis management and almost certainly worsens outcomes, particularly in low-resource systems. The purpose of this study was to examine the prevalence, etiology, and outcomes of sepsis among a cohort of critically ill patients in a referral hospital of Malawi, with a focus on the prevalence of culture-confirmed bacteremia and urinary tract infections.

Diabetes mellitus is a major cause of morbidity and mortality in Scotland and worldwide, with an increasing prevalence. In 2009 there were around 228,000 people registered as having diabetes in Scotland, an increase of 3.6% from the preceding year. This increase relates, in part, to the increasing a...ge of the population, an increase in obesity and also perhaps to increasing survival of those with diabetes.

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.

Since the discovery of insulin nearly 100 years ago, advances in diabetes treatments and therapies have transformed the lives of people
with diabetes (PwD), notably reducing the daily burden of its management.
Newer technologies, including those driven by artificial intelligence, have the potentia...l to further improve the quality of life of PwD and help
identify and diagnose people at risk of developing Type 2 diabetes and diabetes-related complications early. However, medical and technological advances alone are not enough to fix the diabetes challenge. It is also critical to acknowledge the complexity and the seriousness of diabetes, its impact on the quality of life and well-being of over 32 million PwD in the EU and the financial burden it represents for health systems and society at large.

To survive and thrive, children and adolescents need good health, adequate nutrition, security, safety and a supportive clean environment, opportunities for early learning and education, responsive relationships and connectedness, and opportunities for personal autonomy and self-realization. To prom...ote their health and wellbeing, children and adolescents need support from parents, families, communities, surrounding institutions, and an enabling environment. Scheduled well care visits provide a critical opportunity for support of individual children, adolescents, parents, caregivers and families promote health and wellbeing. This guidance on scheduled child and adolescent well-care visits is the first in a series of publications to support the operationalization of the comprehensive agenda for child and adolescent health and wellbeing. It provides guidance on what is required to strengthen health systems and services to ensure healthy growth and development of all children and adolescents, and to support their parents and caregivers.
The guidance focuses on scheduled routine contacts with providers to support children and adolescents in their growth and developmental trajectory, as well as their primary caregivers and families. It outlines the rationale and objectives of well care visits and proposes a minimum 17 scheduled visits; describes the expected tasks during a contact; provides age-specific content to be address during each contact; and proposes actions to build on and maximize existing opportunities and resources.

Heart failure (HF) is a global public health concern with disproportionate socioeconomic, morbidity and mortality burden on low- and middle-income countries (LMICs). This review summarises contemporary data on the demographic and clinical characteristics, aetiologies, treatment, economic burden and ...outcomes of HF in LMICs. Patients with HF in LMICs are younger than those from high-income countries (HICs) and present at advanced stages of the disease. Hypertension, ischaemic heart disease (IHD), cardiomyopathy (CMO), and rheumatic heart disease (RHD) are the leading causes of HF in LMICs. The contribution of infectious diseases to HF remains prominent in many LMICs. Most health facilities in LMICs lack adequate diagnostic tools for HF, and the use of evidence-based medical and device therapies is suboptimal. Further, HF in LMICs is associated with prolonged hospital stay and high in-hospital and one-year mortality. Finally, HF has profound economic impact on individual patients who, mostly, have no health insurance, and on societies where patients are young, comprising those who have the greatest potential to contribute to economic productivity.

Sexual abuse perpetrated against children is one of the most significant crises of our time. Child sexual abuse is a significant risk factor for children, in common with other forms of child maltreatment. Sexual abuse can have severe short- and long-term consequences on the physical, mental, social,... emotional and economic well-being of children, families and communities. In emergencies, the threat of all forms of child abuse and gender-based violence (GBV), including child sexual abuse, is acute and widespread.
