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.

Cardiovascular diseases (CVDs) are a growing public health problem in Ghana and other African countries. Strokes and other CVDs have become a leading cause of death due to increasing risk factors such as hypertension. According to the Global Burden of Disease study (GBD), ischaemic heart disease was... the fourth leading cause of death in Ghana in 2016. The prevalence of hyper-
tension, a major risk factor for CVDs, is increasing rapidly and ranges from 19% to 48%, according to the Ghana Health Service Annual Report, 2017, due to rising life expectancy and the increasing prevalence of contributing factors such as overweight/obesity. Early diagnosis and adequate management of the risk factors can reduce the fatal consequences of CVDs.
At the heart of improving risk assessment and management of CVDs are nationally approved guidelines, which facilitate standardisation of care approaches.
These guidelines developed by experts from all levels of health care and stakeholders capture all recommended approaches and necessary information for clinicians and other healthcare workers on CVDs. They also serve as a practical guide for assessing and managing the most important CVDs prevalent in Ghana and can be used at all levels of care namely health facilities without a doctor; with a general practitioner and with a physician specialist.

Q7. SCOPING QUESTION: In adults with moderate-severe depressive disorder, what is the effectiveness and safety of antidepressant medication (ADM) in comparison with psychological treatment?
The WHO mhGAP programme’s existing guidelines recommend that either structured brief psychological treatm...ents (e.g., interpersonal psychotherapy or cognitive behavioural therapy, including behavioural activation) or antidepressant medication (e.g., SSRIsi and tricyclic antidepressants) be considered in adults with moderate-severe depression. Health care workers need to know whether these treatments have different effects, including side-effects, in treating depressive disorder in the short and long term, in order to improve clinical decision-making.

Surge in climate change-related disasters poses growing threat to food security
The 2019 edition treating data for 2018 marks sustained international efforts dedicated to reporting on, analysing and understanding the year-to-year variations and long-term trends of a changing climate.
Previous crises, such as the Ebola virus disease (EVD) in West Africa in 2014, indicate the direct impact movement restrictions and disease containment efforts have on food availability, access, utilization and violence – particularly gender-based violence (GBV). The importance of maintaining and ...upscaling food security interventions for the most vulnerable populations, alongside the health sector’s efforts to avert disease spread, is therefore undeniable. The COVID-19 outbreak in South Sudan threatens to paralyze an already fragile food system and negatively impact more than 6.5 million people in South Sudan who remain vulnerable. At the same time, the core national capacities for prevention, preparedness and response for public health events is limited, and the healthcare system has been weakened by years of conflict, poor governance and low investments.

Over the past two decades, Afghanistan has depended on international donor support to fund essential services like health care. But this donor support has been falling for years and will likely to continue do so—perhaps precipitously—following the announcement by United States President Joe Bide...n that the US will withdraw all US forces from Afghanistan by September 11, 2021. This decline in funding has already had a harmful—and life-threatening—impact on the lives of many Afghan women and girls, as it affects access to, and quality of, health care.

It is often observed that educated women have lower birth rates than do the less educated, inviting a causal interpretation. However, educated women also differ from those who have never attended school in a
variety of other ways: the two factors are multiply related. This article analyzes the rela...tionship between schooling and fertility in contemporary Cameroon as both a statistical and a social phenomenon, using data from the 1998 Cameroon DHS alongside ethnographic field data collected by

Noncommunicable diseases (NCDs) such as cancer, cardiovascular disease, diabetes and chronic respiratory diseases and their risk factors are an increasing public health and development challenge in Kazakhstan. This report provides evidence through three analyses that NCDs reduce economic output and ...discusses potential options in response, outlining details of their relative returns on investment. An economic burden analysis shows that economic losses from NCDs (direct and indirect costs) comprise 2.3 trillion tenge, equivalent to 4.5% of gross domestic product in 2017. An intervention costing analysis provides an estimate of the funding required to implement a set of policy interventions for prevention and clinical interventions. A cost–benefit analysis compares these implementation costs with the estimated health gains and identifies which policy packages would give the greatest returns on investment. For example, the salt policy package achieved a benefit-to-cost ratio of 118.4 over 15 years, a return of more than 118 tenge for every 1 tenge invested.
