Long-term exposure of humans to air pollution enhances the risk of cardiovascular and respiratory diseases. A novel Global Exposure Mortality Model (GEMM) has been derived from many cohort studies, providing much-improved coverage of the exposure to fine particulate matter (PM2.5). We applied the GE...MM to assess excess mortality attributable to ambient air pollution on a global scale and compare to other risk factors.
Methods and results
We used a data-informed atmospheric model to calculate worldwide exposure to PM2.5 and ozone pollution, which was combined with the GEMM to estimate disease-specific excess mortality and loss of life expectancy (LLE) in 2015. Using this model, we investigated the effects of different pollution sources, distinguishing between natural (wildfires, aeolian dust) and anthropogenic emissions, including fossil fuel use. Global excess mortality from all ambient air pollution is estimated at 8.8 (7.11–10.41) million/year, with an LLE of 2.9 (2.3–3.5) years, being a factor of two higher than earlier estimates, and exceeding that of tobacco smoking. The global mean mortality rate of about 120 per 100 000 people/year is much exceeded in East Asia (196 per 100 000/year) and Europe (133 per 100 000/year). Without fossil fuel emissions, the global mean life expectancy would increase by 1.1 (0.9–1.2) years and 1.7 (1.4–2.0) years by removing all potentially controllable anthropogenic emissions. Because aeolian dust and wildfire emission control is impracticable, significant LLE is unavoidable.
Conclusion
Ambient air pollution is one of the main global health risks, causing significant excess mortality and LLE, especially through cardiovascular diseases. It causes an LLE that rivals that of tobacco smoking. The global mean LLE from air pollution strongly exceeds that by violence (all forms together), i.e. by an order of magnitude (LLE being 2.9 and 0.3 years, respectively).

This Rapid Gender Analysis provides preliminary information and observations on the different needs, capacities and coping strategies of Venezuelan migrant and refugee women, men, boys, and girls in Colombia. It seeks to understand how gender roles and relations have changed as a result of the crisi...s and share recommendations for how the humanitarian community can more effectively consider these changing dynamics to better meet the different needs of women, men, boys and girls of different ages, abilities and other contextually relevant forms of diversity. The refugee and migrant crisis in Colombia is characterized by gendered dynamics and has taken a significant toll on the health and welfare on all those affected, but particularly on women and girls. Refugee and migrant women and girls face profound vulnerabilities as they leave Venezuela and either cross Colombia or stay in various locations across the country; this is even more the case for those at increased risk, such as indigenous populations, adolescent girls, etc.

In this paper they make estimates of the potential short-term economic impact of COVID-19 on global monetary poverty through contractions in per capita household income or consumption.
The estimates are based on three scenarios: low, medium, and high global contractions of 5, 10, and 20 per cent;... we calculate the impact of each of these scenarios on the poverty headcount using the international poverty lines of US$1.90, US$3.20 and US$5.50 per day.
The estimates show that COVID poses a real challenge to the UN Sustainable Development Goal of ending poverty by 2030 because global poverty could increase for the first time since 1990 and, depending on the poverty line, such increase could represent a reversal of approximately a decade in the world’s progress in reducing poverty.
In some regions the adverse impacts could result in poverty levels similar to those recorded 30 years ago. Under the most extreme scenario of a 20 per cent income or consumption contraction, the number of people living in poverty could increase by 420–580 million, relative to the latest official recorded figures for 2018.

Chagas disease, also known as American trypanosomiasis, is a neglected tropical disease transmitted by triatomine insects, first identified in 1909. Chagas disease affects approximately 6–7 million peop...le globally and is highly prevalent in Latin America where most cases are reported. However, there is increasing evidence that Chagas disease is now an important public health issue outside the “classical” endemic countries due to population migration. Our understanding of Chagas disease, including its pathologies and factors relating to progression, remains to date limited, and is also challenged by lack of diagnosis and highly effective treatment. This systematic review aims to describe studies with Chagas patients receiving antiparasitic treatment. Databases were searched for relevant studies published after 1997, and the results of these searches were screened.

In 2016, Senegal made a minimal advancement in efforts to eliminate the worst forms of child labor. In June, the Government launched an initiative to remove tailbés from the street and prosecute marabouts that perpetrate crimes against their students; however, no marabouts were prosecuted during th...e reporting period. Children in Senegal perform dangerous tasks in gold mining. Children also engage in the worst forms of child labor, including in forced begging, sometimes as a result of human trafficking.

EQUIP: Ensuring Quality in Psychological Support is a joint WHO/UNICEF project to improve the competence of helpers and the consistency and quality of training and service delivery. The EQUIP platform makes freely available competency assessment tools and e-learning courses to support governments, t...raining institutions, and non-governmental organizations, both in humanitarian and development settings, to train and supervise the workforce to deliver effective psychological support to adults and children.
EQUIP enhances training and supervision for improved mental health and psychosocial support services.
EQUIP used a consensus-building approach including key stakeholders to develop the evidence-informed competency-based training materials and guidance, as well as the competency assessment tools. These resources have been tested in Ethiopia, Jordan, Kenya, Lebanon, Nepal, Peru, Uganda and Zambia, with results demonstrating training improvements in groups that used the EQUIP platform. For example, use of EQUIP in Lebanon with children and adolescents led to an increase in mastery of core helping skills compared to standard training approaches.

Background
Equity and inclusion are important principles in policy development and implementation. The aim of this study is to explore the extent to which equity and inclusion were considered in the development of Malawi’s National Disability Mainstreaming Strategy and Implementation Plan.
Met...hods
We applied an analytical methodology to review the Malawi’s National Disability Mainstreaming Strategy and Implementation Plan using the EquIPP (Equity and Inclusion in Policy Processes) tool. The EquIPP tool assesses 17 Key Actions to explore the extent of equity and inclusion.
Results
The development of the Malawi National Disability Mainstreaming Strategy and Implementation Plan was informed by a desire to promote the rights, opportunities and wellbeing of persons with disability in Malawi. The majority (58%) of the Key Actions received a rating of three, indicating evidence of clear, but incomplete or only partial engagement of persons with disabilities in the policy process. Three (18%) of the Key Actions received a rating of four indicating that all reasonable steps to engage in the policy development process were observed. Four (23%) of the Key Actions received a score five indicating a reference to Key Action in the core documents in the policy development process.
Conclusions
The development of disability policies and associated implementation strategies requires equitable and inclusive processes that consider input from all stakeholders especially those whose wellbeing depend on such policies. It is pivotal for government and organisations in the process of policy or strategy development and implementation, to involve stakeholders in a virtuous process of co-production – co-implementation – co-evaluation, which may strengthen both the sense of inclusion and the effectiveness of the policy life-cycle.

Since 2001, several Demographic and Health Surveys (DHS) include HIV
testing. For many countries, in particular in sub-Saharan Africa, DHS are
the only national source of data in general population. Several DHS collect
latitude and longitude of surveyed clusters but the sampling method is not
ap...propriate to derive local estimates: sample size is not large enough for a
direct spatial interpolation.
We developed a generic approach to map spatial regional trends of HIV
prevalence from DHS. We present how our results from Burkina Faso 2003
DHS shed new light on HIV epidemics.

The purpose of this document is to provide guidance on the use of pooled sample testing strategy in coronavirus disease (COVID-19)
testing laboratories of the African Union Member States for scaling up SARS-CoV-2 nucleic acid testing capacity with the available resources. The current document descr...ibes the effect of factors such as the prevalence of COVID-19 in the population to be tested, the homogeneity of pools, and the sensitivity of the molecular test in optimal pool size determination. It also highlights the importance of monitoring the prevalence of COVID-19 in a population to be tested and proper validation of the test, to limit the potential for false-negative results. Validation studies to determine the optimal pool size by testing laboratories are recommended as the optimum approach. A safe, simple ‘two-stage pooling’ option has been indicated in this guidance to be used by laboratories until such validation can be achieved.

eLife 2020;9:e52072. The Triatominae are vectors for Trypanosoma cruzi, the aetiological agent of the neglected tropical Chagas disease. Their distribution stretches across Latin America, with some species occurring outside of the Americas. In particular, the cosmopolitan vector, Triatoma rubrofasci...ata, has already been detected in many Asian and African countries. We applied an ensemble forecasting niche modelling approach to project the climatic suitability of 11 triatomine species under current climate conditions on a global scale. Our results revealed potential hotspots of triatomine species diversity in tropical and subtropical regions between 21 ̊N and 24 ̊S latitude. We also determined the climatic suitability of two temperate species (T. infestans, T. sordida) in Europe, western Australia and New Zealand. Triatoma rubrofasciata has been projected to find climatically suitable conditions in large parts of coastal areas throughout Latin America, Africa and Southeast Asia, emphasising the importance of an international vector surveillance program in these regions.

DHS Working Papers No. 69
This paper uses data from the three Indian National Family Health Surveys (1992-93, 1998-99, 2005-06) to examine how the relationship between household wealth and child mortality evolved during a time of significant economic change in India. The main predictor is a new... measure of household wealth that captures changes in wealth over time. Outcomes include neonatal mortality, postneonatal mortality, child mortality, and under-five mortality. Multivariate analysis is conducted at the national, urban, rural, and regional levels.
Results indicate that the overall relationship between household wealth and mortality weakened over time, as evidenced by the coefficients for under-five mortality at the national level.

With development, people around the world have become wealthier and live longer. At the same time, development can lead to growing inequalities within and between nations. This paper analyses inequalities related to disability and how they vary across countries by development level. Using internatio...nally comparable data on disability inequalities in 40 countries, we assess disability inequalities through the use of regression analyses with a variety of development measures. Results support the hypothesis only partially: disability inequalities related to education, employment, and multidimensional poverty are found to be significantly larger in countries at higher levels of development. However, this is not the case for rates of access to water, sanitation, clean fuel, electricity, housing, and assets. These results, overall, hold when using different development and
outcome indicators, and when focusing on specific subgroups of the population. The potential implications of these findings are discussed. Further research is needed to understand, for education and employment, the factors and processes that contribute to larger disability inequalities in countries at higher levels of development and what strategies might be pursued to reduce them.

Strict storage recommendations for insulin are difficult to follow in hot tropical regions and even more challenging in conflict and humanitarian emergency settings, adding an extra burden to the management of people with diabetes. According to pharmacopeia unopened insulin vials must be stored in a... refrigerator (2–8°C), while storage at ambient temperature (25–30°C) is usually permitted for the 4-week usage period during treatment. In the present work we address a critical question towards improving diabetes care in resource poor settings, namely whether insulin is stable and retains biological activity in tropical temperatures during a 4-week treatment period. To answer this question, temperature fluctuations were measured in Dagahaley refugee camp (Northern Kenya) using log tag recorders. Oscillating temperatures between 25 and 37°C were observed. Insulin heat stability was assessed under these specific temperatures which were precisely reproduced in the laboratory. Different commercialized formulations of insulin were quantified weekly by high performance liquid chromatography and the results showed perfect conformity to pharmacopeia guidelines, thus confirming stability over the assessment period (four weeks). Monitoring the 3D-structure of the tested insulin by circular dichroism confirmed that insulin monomer conformation did not undergo significant modifications. The measure of insulin efficiency on insulin receptor (IR) and Akt phosphorylation in hepatic cells indicated that insulin bioactivity of the samples stored at oscillating temperature during the usage period is identical to that of the samples maintained at 2–8°C. Taken together, these results indicate that insulin can be stored at such oscillating ambient temperatures for the usual four–week period of use. This enables the barrier of cold storage during use to be removed, thereby opening up the perspective for easier management of diabetes in humanitarian contexts and resource poor settings.

The Government of Malawi’s Health Sector Strategic Plan II highlights the importance of service integration; however, in practice, this has not been fully realized. We conducted a mixed methods evaluation of efforts to systematically implement integrated family planning and immunization services i...n all health facilities and associated community sites in Ntchisi and Dowa districts during June 2016–September 2017. Methods included secondary analysis of service statistics (pre- and postintervention), focus group discussions with mothers and fathers of children under age one, and in-depth interviews with service providers, supervisors, and managers. Results indicate statistically significant increases in family planning users and shifts in use of family planning services from health facilities to community sites. The intervention had no effect on immunization doses administered or dropout rates. According to mothers and fathers, benefits of service integration included time savings, convenience, and improved understanding of services. Provision and use of integrated services were affected by availability of human resources and commodities, community linkages, data collection procedures and availability, sociocultural barriers, organization of services, and supervision and commitment of health surveillance assistants. The integration approach was perceived to be feasible and beneficial by clients and providers.
