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.

Tackling Tuberculosis in Under-Served Populations: A Resource for TB Control Boards and their partners
"The aim of this book remains as for the first edition, namely to provide an initial point of ready
reference for the identification of hazards and precautions for dangerous chemicals. It is targeted
not only at those in the chemical and process industries, but also anyone likely to work with
che...micals within industry and in the service sector, e.g. hospitals, universities, research laboratories,
engineering, agriculture, etc. "

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.

Sleeping sickness is controlled by case detection and treatment but this often only reaches less than 75% of the population. Vector control is capable of completely interrupting HAT transmission but is not used because of expense. We conducted a full scale field trial of a refined vector control tec...hnology. From preliminary trials we determined the number of insecticidal tiny targets required to control tsetse populations by more than 90%. We then carried out a full scale, 500 km2 field trial covering two HAT foci in Northern Uganda (overall target density 5.7/km2). In 12 months tsetse populations declined by more than 90%. A mathematical model suggested that a 72% reduction in tsetse population is required to stop transmission in those settings. The Ugandan census suggests population density in the HAT foci is approximately 500 per km2. The estimated cost for a single round of active case detection (excluding treatment), covering 80% of the population, is US$433,333 (WHO figures). One year of vector control organised within country, which can completely stop HAT transmission, would cost US$42,700. The case for adding this new method of vector control to case detection and treatment is strong. We outline how such a component could be organised.
