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.

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.

The way land resources – soil, water and biodiversity – are currently mi...smanaged and misused threatens the health and continued survival of many species on Earth, including our own, warns a stark new report from the United Nations Convention to Combat Desertification (UNCCD).
It also points decision makers to hundreds of practical ways to effect local, national and regional land and ecosystem restoration.

What are the FP and CAC competencies?
Through the clear articulation of the family planning and comprehensive abortion care (FP and CAC) competencies for the primary health care workforce, the aim is to advance improvements in FP and CAC service delivery by aligning health worker education approach...es with population health needs and health system demands.
This document, which describes these competencies in detail, is intended to:
be a foundational tool to be adopted and adapted by educators and regulators for FP and CAC providers (students) with a pre-service training pathway of at least 12 months;
describe competencies that are relevant to current and future health practice;
enable widespread use of the competencies not only for curriculum development for pre-service education, but also for in-service education, regulation, qualifications, quality assurance, personal development, performance evaluation, recruitment, management and career progression;
focus on the core functions of FP and CAC providers within broader efforts towards achieving universal health coverage

Financing Global Health 2013: Transition in an Age of Austerity, IHME’s fifth annual report on global health expenditure, depicts financing trends that underline the resilience of development assistance for health. This year’s updated estimates show that despite lackluster economic growth and fi...scal cutbacks in many developed countries, total assistance remained steady, reaching an all-time high of $31.3 billion in 2013. While annual increases have leveled off since 2010, continued international funding is a sign of the international development community’s enduring support for global health.
The report also shows shifts in sources of financing. As funding from many bilateral donors and development banks has declined, growth in funding from the GAVI Alliance, the Global Fund to Fight AIDS, Tuberculosis and Malaria, non-governmental organizations, and the UK government is counteracting these cuts. Development assistance for different health issues is tracked up to 2011, revealing that the greatest increase in funding was for maternal, newborn, and child health.

Care for persons with noncommunicable diseases (NCDs), such as cardiovascular disease, diabetes, cancer, and chronic obstructive pulmonary disease, is a major health priority for most countries worldwide, particularly for low-middle income countries where the problem seems to be worsening. Globally,... research demonstrates that the vast majority of people with NCDs receive suboptimal care. Many people living with chronic conditions remain undiagnosed and unaware of their condition, while many others remain untreated or with inadequate control. Meanwhile the premature mortality caused by NCDs remains high in many countries. In response to the global epidemic of NCDs, the World Health Organization (WHO) launched the Global Strategy for the Prevention and Control of Noncommunicable Diseases in 2012, which establishes 9 voluntary global targets and indicators to be considered by Member States when formu- lating national plans to combat NCDs.

Millennium Development Goal 8E aims for affordable access to essential medicines. Essential medicines, as defined by WHO, are those that “satisfy the health-care needs of the majority of the population” and that should therefore “be available at all times in adequate amounts”. However, there... is a category of medicines that faces a unique challenge in terms of availability. These are the medicines governed by the international conventions on narcotic and psychotropic substances. “Controlled medicines” is the common definition for pharmaceuticals whose active principles are listed under the 1961 United Nations Single Convention on Narcotic Drugs as amended by the 1972 Protocol, such as morphine and methadone; the 1971 United Nations Convention on Psychotropic Substances, such as diazepam and buprenorphine; and the 1988 United Nations Convention against Illicit Traffic in Narcotic Drugs and Psychotropic Substances, such as ergometrine and ephedrine. The conventions list substances in “Schedules” according to their different levels of potential for abuse and harm, and the commensurate severity of control measures to be applied by countries.

WHO guidelines on the pharmacological treatment of persisting pain in children with medical illnesses
This report presents, for the first time, a global assessment of the extent to which health care facilities provide essential water, sanitation and hygiene (WASH) services. Drawing on data from 54 low- and middle-income countries, the report concludes that 38% lack access to even rudimentary levels ...of water, 19% lack sanitation and 35% do not have water and soap for handwashing. When a higher level of service is factored in, the situation deteriorates significantly. A number of areas require urgent action and WHO will work with UNICEF, Governments and other partners to develop a global plan to address the most pressing needs and ensure that all health care facilities have WASH services.

Ghana is attracting global attention for efforts to provide health insurance to all citizens through the National Health Insurance Scheme (NHIS). With the program’s strong emphasis on maternal and child health, an expectation of the program is that members will have increased use of relevant servi...ces. The NHIS does appear to enable pregnant women to access services and allow caregivers to seek care early for sick children, but both the quantitative and qualitative assessments also indicated that the poor and least educated were less likely to have insurance than their wealthier and more educated counterparts.
