Microplastic debris floating at the ocean surface can harm marine life. Understanding the severity of this harm requires knowledge of plastic abundance and distributions. Dozens of expeditions measuring microplastics have been carried out since the 1970s, but they ha...ve primarily focused on the North Atlantic and North Pacific accumulation zones, with much sparser coverage elsewhere. Here, we use the largest dataset of microplastic measurements assembled to date to assess the confidence we can have in global estimates of microplastic abundance and mass. We use a rigorous statistical framework to standardize a global dataset of plastic marine debris measured using surface-trawling plankton nets and coupled this with three different ocean circulation models to spatially interpolate the observations. Our estimates show that the accumulated number of microplastic particles in 2014 ranges from 15 to 51 trillion particles, weighing between 93 and 236 thousand metric tons, which is only approximately 1% of global plastic waste estimated to enter the ocean in the year 2010. These estimates are larger than previous global estimates, but vary widely because the scarcity of data in most of the world ocean, differences in model formulations, and fundamental knowledge gaps in the sources, transformations and fates of microplastics in the ocean.

Résumé.
Malgré les efforts de promotion des mutuelles de santé depuis une décennie et l’existence d’une vingtaine de compagnies privées proposant des polices d’assurance maladie, moins de 1% de la population camerounaise bénéficie d’une couverture maladie. Les facteurs sous jacents ...sont entre autres : (i) la méfiance des ménages vis-à-vis des mutuelles de santé et des assureurs privés; (ii) l’absence d’obligation d’une assurance maladie qui en fait un produit de luxe ; (iii) l’ignorance des avantages des mécanismes assurantiels; (iv) la pauvreté et le montant élevé des primes d’adhésion et des cotisations annuelles ; et (v) la forte prévalence de l’emploi dans le secteur informel (80,6%). Pour y faire face nous proposons de : 1) Créer et pérenniser un environnement favorable à la promotion et au développement des MS ; 2) Subventionner les primes par le Gouvernement, les Partenaires et les Municipalités pour en réduire le prix d’achat ; 3) Instituer une collecte flexible des primes et établir un dispositif attractif de mutualisation du risque et des procédures d’achat qui inspirent confiance aux usagers et aux prestataires des soins.

This document has been developed to provide training and guidance on how to integrate a human rights approach in mental health and related areas, based on international human rights instruments, in particular the UN Convention on the Rights of Persons with Disabilities (CRPD).
This study aimed to analyze the geographical distribution of coronavirus disease 2019 (COVID-19) and to identify high-risk areas in space and time for the occurrence of cases and deaths in the indigenous population of Brazil. This is an ecological study carried out between 24 March and 26 October 20...20 whose units of analysis were the Special Indigenous Sanitary Districts. The Getis-Ord General G and Getis-Ord Gi* techniques were used to verify the spatial association of the phenomena and a retrospective space–time scan was performed. There were 32 041 confirmed cases of COVID-19 and 471 deaths. The non-randomness of cases (z score = 5.40; P < 0.001) and deaths (z score = 3.83; P < 0.001) were confirmed. Hotspots were identified for cases and deaths in the north and midwest regions of Brazil. Sixteen high-risk space–time clusters were identified for the occurrence of cases with a higher RR = 21.23 (P < 0.001) and four risk clusters for deaths with a higher RR = 80.33 (P < 0.001). These clusters were identified from 22 May and were active until 10 October 2020. The results indicate critical areas in the indigenous territories of Brazil and contribute to better directing the actions of control of COVID-19 in this population.

La sexualité des adolescents est devenue un sujet de préoccupation de santé publique, avec l’extension du SIDA au cours de ces dernières années, particulièrement en milieu urbain.
Quels sont les déterminants des pr...atiques sexuelles des adolescents ? Pourquoi certaines
pratiques peuvent-elles être qualifiées de comportements à risque ? Dans quelles mesures les politiques de santé publique pourront-elles résoudre les problèmes liés à ces pratiques
sexuelles ? C’est pour apporter des éléments de réponse à ces questions que l’enquête sur le comportement sexuel a été menée auprès de 806 adolescents filles et garçons dans la ville de Bangui. Huit discussions de groupes ont été également organisées avec ces adolescents et leurs parents.

This training and guidance module addresses the use of coercive and violent practices in mental health and related services with a particular focus on seclusion and restraint. It aims to promote a greater understanding of why these practices are used and build practical skills to help end these prac...tices. While the module itself focuses on ending these practices in the health care setting, much of the content can also be applied in other settings where seclusion and restraint occur, for example in the home and in the wider community.

Cholera is a transmissible diarrhoeal infection caused by Vibrio cholerae. Endemic and/or epidemic in over 40 countries (mainly in Africa and Asia), cholera continues to be a major global public health issue.
The World Health Organization (WHO) estimates that the number of cases reported worldwid...e represents in reality only 5 to 10% of actual cases.
This guide is intended for medical and non-medical staff responding to a cholera outbreak. It attempts to provide concrete answers to the questions and problems faced by staff, based on the recommendations of reference organisations, such as WHO and UNICEF, as well as Médecins Sans Frontières’ experience in the field.
It is divided into 8 chapters. Chapter 1, Cholera overview, outlines the epidemiological and clinical features of cholera. Chapter 2, Outbreak investigation, explains the method and stages of a field investigation, from the alert to implementation of initial activities. Chapter 3, Cholera control measures, details measures and tools to prevent and/or control cholera transmission and mortality in populations affected, or at risk of being affected, by an epidemic (curative care, prevention means and health promotion activities). Chapter 4, Strategies for epidemic response, addresses the roll-out strategies of the measures described in Chapter 3 which depend on context (e.g. urban, rural, endemic, non-endemic setting, etc.), resources and particular constraints. Chapter 5, Cholera case management, details the different stages of cholera treatment, from diagnosis through to cure.
Chapter 6, Setting up cholera treatment facilities, focuses on the installation of treatment facilities that vary in size and complexity according to operational requirements (treatment centres and units and oral rehydration points). Chapter 7, Organisation of cholera treatment facilities, describes the organisation of these specialized facilities in terms of human resources, supply, water, hygiene and sanitation, etc. Chapter 8, Monitoring and evaluation, presents the key data to be collected and analysed during an epidemic to facilitate a tailored response and evaluate its quality and effectiveness.
The guide includes various practical tools in the appendices to facilitate activities (e.g. water quality tests, job descriptions, documents, etc.). Moreover, the toolbox also contains additional tools in editable formats (individual patient file, cholera case register, pictograms).
Despite all efforts, it is possible that certain errors may have been overlooked in this guide. Please inform the authors of any errors detected.
To ensure that this guide continues to evolve while remaining adapted to field realities, please send any comments or suggestions.
