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.

Stats SA has released an in-depth report on persons with disabilities. The report, written using Census 2011 data, is the first in a series of in-depth analyses of various Census 2011 variables, such as ageing and education.
The report provides statistical evidence relating to the prevalence of dis...ability and characteristics of persons with disabilities at both individual and household levels. Two methods were used to profile disability prevalence and patterns based on the six functional domains, namely seeing, hearing, communication, remembering/concentrating, walking and self-care. These two methods were:
- the level/degree of difficulty in a specific functional domain and;
- the disability index.

This Review summarizes many of the persistent biological alterations associated with childhood maltreatment including changes in neuroendocrine and neurotransmitter systems and pro-inflammatory cytokines in addition to specific alterations in brain areas associated with mood regulation. Finally, I d...iscuss several candidate gene polymorphisms that interact with childhood maltreatment to modulate vulnerability to major depression and PTSD and epigenetic mechanisms thought to transduce environmental stressors into disease vulnerability.

The Mapping Antimicrobial Resistance and Antimicrobial Use Partnership (MAAP) project has conducted a multi-year, multi-country study that provides stark insights on the under-reported depth of the antimicrobial resistance (AMR) crisis across Africa and lays out urgent policy recommendations to addr...ess the emergency.
MAAP reviewed 819,584 AMR records from 2016-2019, from 205 laboratories across Burkina Faso, Cameroon, Eswatini, Gabon, Ghana, Kenya, Malawi, Nigeria, Senegal, Sierra Leone, Tanzania, Uganda, Zambia, and Zimbabwe. MAAP also reviewed data from 327 hospital and community pharmacies and 16 national-level AMC datasets.

This document is the third iteration of the Flash Appeal for Ukraine, which was originally published on 1 March 2022 and revised once in mid-April. This updated Flash Appeal covers the period of 10 months following the onset of the war in Ukraine that started on 24 February 2022 (i.e., from March to... December 2022). The financial requirement of this Flash Appeal reflects the humanitarian needs from March until the end of 2022, taking into account the funding status and the response achievements to date, as well as the realistic projection of response capacity in the second half of the year.
