Plastic pollution is ubiquitous throughout the marine environment, yet estimates of the global abundance and weight of floating plastics have lacked data, particularly from the Southern Hemisphere and remote regions. Here we re...port an estimate of the total number of plastic particles and their weight floating in the world's oceans from 24 expeditions (2007–2013) across all five sub-tropical gyres, costal Australia, Bay of Bengal and the Mediterranean Sea conducting surface net tows (N = 680) and visual survey transects of large plastic debris (N = 891). Using an oceanographic model of floating debris dispersal calibrated by our data, and correcting for wind-driven vertical mixing, we estimate a minimum of 5.25 trillion particles weighing 268,940 tons. When comparing between four size classes, two microplastic <4.75 mm and meso- and macroplastic >4.75 mm, a tremendous loss of microplastics is observed from the sea surface compared to expected rates of fragmentation, suggesting there are mechanisms at play that remove <4.75 mm plastic particles from the ocean surface.

Two adjectives raise an issue for communicators working on Chagas disease (CD): “invisible and silent”. Two adjectives that can be ascribed to other neglected tropical diseases (NTD), but which are part of the essence of CD. Br...inging CD out of its situation of neglect and oblivion is a mission entrusted mainly to the world of communication as well as of science, politics and financial resources. However, communication has not always been considered among the priorities in the approach to the disease, except in valuable exceptions, some of which we have seen in the preceding article.

After almost eight bloody years, the war in Syria finally appears to be reaching the endgame. The Assad regime controls some two-thirds of the country. In the northwest, the regime of Syrian President Bashar al-Assad has launched an offensive against opposition-controlled Idlib governorate under the... cover of a brutal Russian bombing campaign. Upwards of 3 million Syrians in Idlib are under threat. Meanwhile, in northeast Syria, the Syrian Democratic Forces—the Syrian Kurdish dominated militia backed by the United States—have dislodged the Islamic State and now control one-third of the country. However, the humanitarian situation in the northeast remains extremely fragile and could deteriorate quickly. Indeed, over a third of the 4 million people in this area need humanitarian assistance and some 600,000 are displaced.

A partir de que el SARS-CoV-2 se detectó en China en diciembre de 2019, la COVID-19 se ha convertido rápidamente
en una pandemia. Los pacientes con COVID-19 presentan síntomas respiratorios inespecíficos de intensidad variable y
en ocasiones se les debe prestar ventilación asistida avanzada. ...Actualmente, el diagnóstico de COVID-19 se confirma
mediante la realización de pruebas analíticas, a saber, la determinación de ARN vírico a través de la reacción en

Malaria is an important disease that has a global distribution and significant health burden. The spatial limits of its distribution and seasonal activity are sensitive to climate factors, as well as the local capacity to control the disease. Malaria is also ...one of the few health outcomes that has been modeled by more than one research group and can therefore facilitate the first model intercomparison for health impacts under a future with climate change. We used bias-corrected temperature and rainfall simulations from the Coupled Model Intercomparison Project Phase 5 climate models to compare the metrics of five statistical and dynamical malaria impact models for three future time periods (2030s, 2050s, and 2080s). We evaluated three malaria outcome metrics at global and regional levels: climate suitability, additional population at risk and additional person-months at risk across the model outputs. The malaria projections were based on five different global climate models, each run under four emission scenarios (Representative Concentration Pathways, RCPs) and a single population projection. We also investigated the modeling uncertainty associated with future projections of populations at risk for malaria owing to climate change. Our findings show an overall global net increase in climate suitability and a net increase in the population at risk, but with large uncertainties. The model outputs indicate a net increase in the annual person-months at risk when comparing from RCP2.6 to RCP8.5 from the 2050s to the 2080s. The malaria outcome metrics were highly sensitive to the choice of malaria impact model, especially over the epidemic fringes of the malaria distribution.

This paper introduces a new dataset of official financing—including foreign aid and other forms of concessional and non-concessional state financing—from China to 138 countries between 2000 and 2014. We use these data to investigate whether and to what extent Chinese aid affects economic growth ...in recipient countries. To account for the endogeneity of aid, we employ an instrumental-variables strategy that relies on exogenous variation in the supply of Chinese aid over time resulting from changes in Chinese steel production. Variation across recipient countries results from a country’s probability of receiving aid. Controlling for year- and recipient-fixed effects that capture the levels of these variables, their interaction provides a powerful and excludable instrument. Our results show that Chinese official development assistance (ODA) boosts economic growth in recipient countries. For the average recipient country, we estimate that one additional Chinese ODA project produces a 0.7 percentage point increase in economic growth two years after the project is committed. We also benchmark the effectiveness of Chinese aid vis-á-vis the World Bank, the United States, and all members of the OECD’s Development Assistance Committee (DAC).

Cases of human monkeypox are rarely seen outside of west and central Africa. There are few data regarding viral kinetics or the duration of viral shedding and no licensed treatments. Two oral drugs, brincidofovir and tecovirimat, have been approved for treatment of smallpox and have demonstrated eff...icacy against monkeypox in animals. Our aim was to describe the longitudinal clinical course of monkeypox in a high-income setting, coupled with viral dynamics, and any adverse events related to novel antiviral therapies.
