Snakebite clinical trials have often used heterogeneous outcome measures and there is an urgent need for standardisation. A globally representative group of key stakeholders came together to reach consensus on a globally relevant set of core outcome measurements. Outcome domains and outcome measurement instruments were identified through searching the literature and a systematic review of snakebite clinical trials. Outcome domains were shortlisted by use of a questionnaire and consensus was reached among stakeholders and the patient group through facilitated discussions and voting. Five universal core outcome measures should be included in all future snakebite clinical trials-mortality, WHO disability assessment scale, patient-specific functional scale, acute allergic reaction by Brown criteria, and serum sickness by formal criteria. Additional syndrome-specific core outcome measures should be used depending on the biting species. This core outcome measurement set provides global standardisation, supports the priorities of patients and clinicians, enables meta-analysis, and is appropriate for use in low-income and middle-income settings.

CONTEXTE
Les essais cliniques sur les morsures de serpent ont souvent utilisé des critères de décision hétérogènes qui demandent à être standardisés.
MÉTHODE
Un groupe d'acteurs clés mondialement représentatifs s'est réuni pour parvenir à un consensus sur un jeu universel de critères de décision de base. Les domaines d'intérêt et les instruments d'évaluation des critères de décision ont été identifiés à partir d'une recherche documentaire et d'un examen systématique des essais cliniques concernant les envenimations par morsure de serpent. Les domaines d'intérêt ont été présélectionnés à l'aide d'un questionnaire et un consensus a été obtenu entre le groupe d'acteurs et un groupe représentatif de patients à la suite de discussions orientées et d'un vote.
RÉSULTATS
Cinq critères de décision de base universels devraient être inclus dans tous les futurs essais cliniques sur les morsures de serpent : la mortalité, l'échelle d'évaluation du handicap de l'OMS, l'échelle fonctionnelle propre à chaque patient, la réaction allergique immédiate selon les critères de Brown et la maladie sérique en fonction de critères formels. D'autres critères de décision spécifiques aux différents syndromes observés lors des envenimations par morsure de serpent doivent être utilisés en fonction de l'espèce responsable de la morsure.
CONCLUSION
Ce jeu universel de critères de décision de base permet une standardisation mondiale, répond aux priorités des patients et des cliniciens, favorise des méta-analyses et est compatible avec une utilisation dans les pays à revenu faible ou intermédiaire.

INTRODUCTION
The crowded conditions within camps for refugees and internally displaced people create risk environments for unmitigated transmission of SARS-CoV-2. Within one such setting, Cox’s Bazar, Bangladesh, MSF distributed face masks in July-August 2020 for use by people living in eight camps to reduce transmission risks. However, uptake of face masks within camp populations and the factors influencing use are not well understood.
METHODS
We conducted a multi-level triangulation mixed-methods study in March 2021 in Cox’s Bazar. Field observations were undertaken in public spaces in four camps, noting individuals’ facemask use (appropriate versus not), use of other types of face covering (e.g., headscarf), and gender. We also analysed photographs posted on Twitter during March 2021 that were geotagged in the Cox’s Bazar area, posted with a specific keyword, or posted by connected accounts and tweets. Photographs were also categorised by facemask/headscarf use and gender. Finally, we conducted 32 in-depth interviews to understand perceptions and barriers around mask use. Qualitative data were analysed thematically using NVivo.
ETHICS
This study was approved by the Office of the Civil Surgeon, Cox’s Bazar, Bangladesh and by the MSF Ethics Review Board.
RESULTS
We made 3,152 public observations. Only 190/3,152 (6%) were using a mask appropriately. Men were more likely to be seen using any visible standard facemask appropriately than women (odds ratio, OR, 1.5, 95% confidence interval 1.1-2.2, p-value 0.037). Most women were observed wearing headscarves that precluded observing if masks were worn underneath. The content of 20 tweets were analysed. One photograph showed one person wearing a mask correctly; in 17 photographs individuals wore no face covering and in 2 wore scarves. Qualitative data suggested participants were aware of the importance of mask use but highlighted several reasons for not wearing them, including the fear of being insulted for wearing a mask due to the association between mask use and having Covid-19; a view that they were unnecessary because there was little Covid-19 in the camps; experiences of physical difficulties or discomfort whilst wearing masks; and a belief that wearing facemasks was unnecessary because “life or death is up to Allah”. Participants highlighted the current shortage of masks in the camps as well as adverse consequences of insufficient masks, and requested further distribution.
CONCLUSION
These findings suggest low adherence to recommendations around mask use in this camp setting. Multiple strategies need to be considered, including better distribution strategies and improved messaging and engagement with religious and community leaders to increase facemask use in settings such as Cox’s Bazar.

There are inefficiencies in current approaches to monitoring patients on antiretroviral therapy in sub-Saharan Africa. Patients typically attend clinics every 1 to 3 months for clinical assessment. The clinic costs are comparable with the costs of the drugs themselves and CD4 counts are measured every 6 months, but patients are rarely switched to second-line therapies. To ensure sustainability of treatment programmes, a transition to more cost-effective delivery of antiretroviral therapy is needed. In contrast to the CD4 count, measurement of the level of HIV RNA in plasma (the viral load) provides a direct measure of the current treatment effect. Viral-load-informed differentiated care is a means of tailoring care so that those with suppressed viral load visit the clinic less frequently and attention is focussed on those with unsuppressed viral load to promote adherence and timely switching to a second-line regimen. The most feasible approach to measuring viral load in many countries is to collect dried blood spot samples for testing in regional laboratories; however, there have been concerns over the sensitivity and specificity of this approach to define treatment failure and the delay in returning results to the clinic. We use modelling to synthesize evidence and evaluate the cost-effectiveness of viral-load-informed differentiated care, accounting for limitations of dried blood sample testing. We find that viral-load-informed differentiated care using dried blood sample testing is cost-effective and is a recommended strategy for patient monitoring, although further empirical evidence as the approach is rolled out would be of value. We also explore the potential benefits of point-of-care viral load tests that may become available in the future.
