Environmental exposure to active pharmaceutical ingredients (APIs) can have negative effects on the health of ecosystems and humans. While numerous studies have monitored APIs in rivers, these employ different analytical methods, m...easure different APIs, and have ignored many of the countries of the world. This makes it difficult to quantify the scale of the problem from a global perspective. Furthermore, comparison of the existing data, generated for different studies/regions/continents, is challenging due to the vast differences between the analytical methodologies employed. Here, we present a global-scale study of API pollution in 258 of the world’s rivers, representing the environmental influence of 471.4 million people across 137 geographic regions. Samples were obtained from 1,052 locations in 104 countries (representing all continents and 36 countries not previously studied for API contamination) and analyzed for 61 APIs. Highest cumulative API concentrations were observed in sub-Saharan Africa, south Asia, and South America. The most contaminated sites were in low- to middle-income countries and were associated with areas with poor wastewater and waste management infrastructure and pharmaceutical manufacturing. The most frequently detected APIs were carbamazepine, metformin, and caffeine (a compound also arising from lifestyle use), which were detected at over half of the sites monitored. Concentrations of at least one API at 25.7% of the sampling sites were greater than concentrations considered safe for aquatic organisms, or which are of concern in terms of selection for antimicrobial resistance. Therefore, pharmaceutical pollution poses a global threat to environmental and human health, as well as to delivery of the United Nations Sustainable Development Goals.

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.

Practically, planetary health presents a new way to approach and solve problems. For example, there is
alignment at the highest levels with global policy frameworks – primarily the Convention on Biological
Diversity Aichi Biodiversity Targets, the Paris Climate Agreement, and the Sustainable Dev...elopment
Goals – which will require collaboration across sectors to make progress. While this alignment validates
integrated concepts like planetary health, it also highlights the need for these concepts to be much
more actionable, so that they can be easily taken up by government decision makers as a way to
achieve goals.

This report is primarily intended for the community of policymakers and researchers concerned about the rising risks of domestic, regional, and global infectious disease epidemics, and the collective failure to take the coordinated actions required to reduce such risks. These risks include the expec...ted health, economic, and societal costs that are borne by countries, regions, and even all nations in the case of pandemics (which are worldwide epidemics). These risks also include the consequences of increasing antimicrobial resistance (AMR) and its spread within regions and globally. A necessary first step is to monitor whether a broad range of stakeholders are acting to prevent outbreaks from becoming epidemics, whether their capacities to respond to epidemics are robust, and whether preparedness to respond to pandemics and limit the resulting economic and health damage is improving. Analyzing the adequacy of these efforts is vitally important for the decisions of policymakers to invest in the public health and disaster-risk management capacities. Early and effective control of disease outbreaks prevents substantial health and economic costs whether or not the disease can spread globally and become a pandemic.

The potential for terrorist use of chemical agents is a noted concern highlighted by the Tokyo sarin gas attacks of 1995. The events of September 11, 2001, increased congressional attention towards reducing the vulnerability of the United States to such unconventional attacks. The
possibility that... terrorist groups might obtain insecure chemical weapons led to increased scrutiny of declared Libyan chemical weapon stockpiles following the fall of the Qadhafi regime. Experts have expressed similar concerns regarding the security and use of Syrian chemical weapons,
reportedly including stocks of nerve (sarin, VX) and blister (mustard gas) agents.

La thèse de Yobouet Inès Kouakou, soutenue à l’Université Claude Bernard Lyon 1, porte sur le traitement d’urgence du paludisme sévère chez l’enfant à l’aide d’une administration intranasale d’artésunate. L’objectif principal de ce travail est d’explorer, in vitro, la voie na...sale comme alternative à la voie intra-rectale recommandée actuellement en pré-hospitalier. L’étude démontre la non-toxicité de formulations d’artésunate sur un modèle de muqueuse nasale humaine, bien que la perméation observée reste faible. Des pistes sont proposées pour améliorer cette perméation, notamment par l’optimisation galénique. La thèse inclut également une revue de la pharmacocinétique de l’artésunate et le développement de méthodes de dosage simples et peu coûteuses, adaptées aux laboratoires à ressources limitées. Ce travail s’inscrit dans une démarche de lutte contre le paludisme, notamment en zones rurales où l’accès aux soins reste difficile.
