Objective: The present study was performed to describe the operational implications of using mid-upper arm circumference (MUAC) as a single admission criterion for treatment of severe acute malnutrition in South Sudan. Design: We performed a retrospective analysis of routine programme data of children with severe acute malnutrition aged 6-59 months admitted to a therapeutic feeding programme using weight-for-height Z-score (WHZ) and/or MUAC. To understand the implications of using MUAC as a single admission criterion, we compared patient characteristics and treatment outcomes for children admitted with MUAC < 115 mm (irrespective of WHZ) v. children admitted with WHZ < −3 and MUAC ≥ 115 mm. Results: Of 2205 children included for analysis, 719 (32·6 %) were admitted to the programme with MUAC < 115 mm and 1486 (67·4 %) with WHZ < −3 and MUAC ≥ 115 mm. Children who would have been admitted using a single MUAC < 115 mm criterion were more severely malnourished and more likely to be female and younger. Compared with children admitted with WHZ < −3 and MUAC ≥ 115 mm, children who would have been admitted using MUAC < 115 mm were less likely to recover (54 % v. 69 %) and had higher risk of death (4 % v. 1 %), but responded to treatment with greater weight and MUAC gains. MUAC < 115 mm would have failed to identify 33 % of deaths, while 98 % were identified by WHZ < −3 alone and 100 % by MUAC < 130 mm. Conclusions: The study shows that MUAC < 115 mm identified more severely malnourished children with a higher risk of mortality but failed to identify a third of the children who died. Admission criteria for therapeutic feeding should be adapted to the programmatic context with consideration for both operational and public health implications. Keywords Child malnutrition Mid-upper arm circumferenceWeight-for-height Z-score Admission criteria Community-based management of acute malnutritionAcute malnutrition represents a major cause of childhood morbidity and mortality worldwide. The number of children under the age of 5 years with severe acute malnutrition (SAM) at any time is currently estimated from prevalence data to be nearly 19 million, with the burden or number of incident cases occurring each year presumably higher (1) . SAM contributes to over a million child deaths annually, as children with SAM are estimated to have an approximately ninefold increased risk of death compared with well-nourished children (2,3) . Traditionally, treatment for SAM was conducted exclusively in in-patient settings, an approach that was both costly and limited access to, and impact of, such programmes.In 2007, a new model for the community-based management of acute malnutrition (CMAM) was endorsed by the WHO, UNICEF, World Food Programme and the UN System Standing Committee on Nutrition, in which children with uncomplicated cases of SAM and appetite could be treated on an out-patient basis with the provision of ready-to-use therapeutic foods and weekly or biweekly follow-up (3) . Increasing evidence and operational experience ha...

During June 2014 to April 2017, the population of Mosul, Iraq lived in a state of increasing isolation from the rest of Iraq due to the city’s occupation by the Islamic State group. As part of a study to develop a generalisable method for estimating the excess burden of non-communicable diseases (NCDs) in conflict-affected settings, in April–May 2017 we conducted a brief qualitative study of self-reported care for NCDs among 15 adult patients who had fled Mosul and presented to Médecins Sans Frontières clinics in the Kurdistan region with hypertension and/or diabetes. Participants reported consistent barriers to NCD care during the so-called Islamic State period, including drug shortages, insecurity and inability to afford privately sold medication. Coping strategies included drug rationing. By 2016, all patients had completely or partially lost access to care. Though limited, this study suggests a profound effect of the conflict on NCD burden.Electronic supplementary materialThe online version of this article (10.1186/s13031-018-0183-8) contains supplementary material, which is available to authorized users.

BackgroundOn a global scale, nearly two billion persons are infected with Mycobacterium tuberculosis. From this vast reservoir of latent tuberculosis (TB) infection, a substantial number will develop active TB during their lifetime, with some being able to transmit TB or Multi-drug- resistant (MDR) TB to others. There is clinical evidence pointing to a higher prevalence of infectious diseases including TB among individuals with Diabetes Mellitus (DM). Furthermore, ageing and diabetes mellitus may further aggravate protein-energy malnutrition (PEM), which in turn impairs T-lymphocyte mediated immunologic defenses, thereby increasing the risk of developing active TB and compromising TB treatment. This article aims to a) highlight synergistic mechanisms associated with immunosenescence, DM and PEM in relation to the development of active TB and b) identify nutritional, clinical and epidemiological research gaps.MethodsTo explore the synergistic relationship between ageing, DM, tuberculosis and PEM, a comprehensive review was undertaken. The MEDLINE and the Google Scholar databases were searched for articles published from 1990 to March 2015, using different MESH keywords in various combinations.ResultsAgeing and DM act synergistically to reduce levels of interferon gamma (IFN- γ), thereby increasing susceptibility to TB, for which cell mediated immunity (CMI) plays an instrumental role. These processes can set in motion a vicious nutritional cycle which can predispose to PEM, further impairing the CMI and consequently limiting host defenses. This ultimately transforms the latent TB infection into active disease. A clinical diagnostic algorithm and clinical guidelines need to be established for this population.ConclusionGiven the increase in ageing population with DM and PEM, especially in resource-poor settings, these synergistic tripartite interactions must be examined if a burgeoning TB epidemic is to be averted. Implementation of a comprehensive, all-encompassing approach to curb transmission is clearly indicated. To this end, clinical, nutritional and epidemiological research gaps must be addressed without a delay.
