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.

.Chronic manifestations of Chagas disease present as disabling and life-threatening condi-tions affecting mainly the cardiovascular and gastrointestinal systems. Although meaningful research has outlined the different molecular mech...anisms underlying Trypanosoma cruzi’s infection and the host-parasite interactions that follow, prompt diagnosis and treatment remain a challenge, particu-larly in developing countries and also in those where the disease is considered non-endemic. This review intends to present an up-to-date review of the parasite’s life cycle, genetic diversity, virulence factors, and infective mechanisms, as well as the epidemiology, clinical presentation, diagnosis, and treatment options of the main chronic complications of Chagas disease.

The WHO estimates that 19 million children aged 15 years or younger are visually impaired. Of these, 1.4 million are irreversibly blind and need visual rehabilitation interventions for full psychological and personal development. The remainder have visual problems that could be prevented or treated.... Identifying children with visual problems early in life so that they can benefit from medical and optical interventions remains a key challenge for most child eye health programmes. Reports from various low-and middle-income countries indicate that the age of children undergoing operation for cataract is frequently too high to achieve maximum benefit.

The Practical manual on laboratory strengthening, 2022 update provides practical guidance on implementation of WHO recommendations and best practices for TB laboratory strengthening. It is an updated version of the GLI Practical Guide to Laboratory Strengthening published in 2017 and provides the la...test practical guidance on use of newly recommended diagnostics as well as guidance in key technical areas, including quality assurance and quality management systems, specimen collection and registration, procurement and supply-chain management, diagnostic connectivity, biosafety, data management, human resources, strategic planning, and model algorithms. The key changes are:
inclusion of recent or updated WHO recommendations for tests to diagnose TB and detect drug resistance;
alignment with the latest WHO critical concentrations for phenotypic drug-susceptibility testing (DST) and the new definitions of pre-XDR-TB and XDR-TB;
updated information on building quality-assured TB testing and management capacity using the Stepwise Laboratory Quality Improvement Process Towards Accreditation (SLIPTA) approach (Score-TB package1);
updated information on assessing, analysing and optimising TB diagnostic networks; and
updated information on the use of next-generation sequencing (NGS) to detect mutations associated with drug resistance for surveillance purposes.
The document also provides references to resources and tools relevant for work on laboratory strengthening.

Hand hygiene is vital for safe health care delivery, yet practices at the point of care remain suboptimal worldwide. A comprehensive research agenda is therefore necessary to improve our understanding of factors influencing hand hygiene behaviour and to strengthen appropriate interventions. This age...nda will provide insightful ideas for researchers to focus their projects and funding proposals and will direct donors towards the areas of hand hygiene evidence that require urgent support and innovation. It will also guide decision-makers and stakeholders at the national and international level and support country efforts in updating and strengthening hand hygiene promotion programmes. Global collaboration and investment in hand hygiene research remain essential to promote safe and effective care worldwide.

This document provides technical guidance on concepts, definitions, indicators, criteria, milestones and tools to assist leprosy programmes in their journey towards the goals of interruption of transmission and elimination of leprosy disease and through the post-elimination period. Importantly, it p...rovides criteria with benchmarks, where possible, for all key aspects of leprosy programmes and services. Not only those related to elimination efforts, but also those related to diagnosis and management of leprosy, leprosy-related disabilities, mental wellbeing, stigma and discrimination and inclusion and participation of persons affected by leprosy. The document emphasises that the elimination of leprosy is a long-term, continuous journey on the one hand, while, on the other, clear milestones can be recognised on the way and programme implementation can be assessed against benchmarks, guiding appropriate action to keep the programme on track.

Little is known about foreign aid provided by private donors. This paper contributes to closing this research gap by comparing the allocation of private humanitarian aid to that of official humanitarian aid awarded to 140 recipient countries over the 2000-2016 period. We construct a new database tha...t offers information on the country in which the headquarters of private donors are located to test whether private donors follow the aid allocation pattern of their home country. Our empirical results confirm that private aid “follows the flag.” This finding is robust against the inclusion of various fixed effects, estimating instrumental variables models, and disaggregating private aid into corporate aid and NGO aid. Donor country-specific estimations reveal that private aid from China, Sweden, the United Kingdom, and the United States “follow the flag.”

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
