Background
Noncommunicable diseases are major contributors to morbidity and mortality worldwide. Modifying the risk factors for these conditions, such as physical inactivity, is thus essential. Addressing the context or circumstances in which physical activity occurs may promote physical activity a...t a population level. We assessed the effects of infrastructure, policy or regulatory interventions for increasing physical activity.
Methods
We searched PubMed, Embase and clinicaltrials.gov to identify randomised controlled trials (RCTs), controlled before-after (CBAs) studies, and interrupted time series (ITS) studies assessing population-level infrastructure or policy and regulatory interventions to increase physical activity. We were interested in the effects of these interventions on physical activity, body weight and related measures, blood pressure, and CVD and type 2 diabetes morbidity and mortality, and on other secondary outcomes. Screening and data extraction was done in duplicate, with risk of bias was using an adapted Cochrane risk of bias tool. Due to high levels of heterogeneity, we synthesised the evidence based on effect direction.
Results
We included 33 studies, mostly conducted in high-income countries. Of these, 13 assessed infrastructure changes to green or other spaces to promote physical activity and 18 infrastructure changes to promote active transport. The effects of identified interventions on physical activity, body weight and blood pressure varied across studies (very low certainty evidence); thus, we remain very uncertain about the effects of these interventions. Two studies assessed the effects of policy and regulatory interventions; one provided free access to physical activity facilities and showed that it may have beneficial effects on physical activity (low certainty evidence). The other provided free bus travel for youth, with intervention effects varying across studies (very low certainty evidence).
Conclusions
Evidence from 33 studies assessing infrastructure, policy and regulatory interventions for increasing physical activity showed varying results. The certainty of the evidence was mostly very low, due to study designs included and inconsistent findings between studies. Despite this drawback, the evidence indicates that providing access to physical activity facilities may be beneficial; however this finding is based on only one study. Implementation of these interventions requires full consideration of contextual factors, especially in low resource settings.

The global prevalence, morbidity and mortality related to childhood asthma among children has increased significantly over the last 40 years. Although asthma is recognized as the most common chronic disease in children, issues of underdiagnosis and undertreatment persist. There are substantial globa...l variations in the prevalence of asthma symptoms in children, with up to 13-fold differences between countries. The rising number of hospital admissions for asthma may reflect an increase in asthma severity, poor disease management and/or the effect of poverty. The financial burden of asthma is relatively high within developed countries (those for which data is available) spending 1 to 2% of their healthcare budget on this condition. Established in 1989, the Global Initiative for Asthma (GINA) attempts to raise awareness about the increasing prevalence of asthma, improve management and reduce the burden of asthma worldwide. Despite global efforts, GINA has not achieved its goal, even among developed nations. There are multiple barriers to reducing the global burden of asthma, including limited access to care and/or medications, and lack of prioritization as a public healthcare priority. In addition, the diversity of healthcare systems worldwide and large differences in access to care require that asthma management guidelines be tailored to local needs.

The Haiti & Dominican Republic Cholera Operation Plan of Action outlines the Red Cross's strategy to combat cholera on the island of Hispaniola following the 2010 outbreak in Haiti. As part of a 10-year national strategy, the plan includes an initial two-year emergency response (2014-2016) with a bu...dget of 9.9 million Swiss francs. The approach focuses on three key areas: improving water and sanitation by repairing and expanding water systems and constructing sanitation facilities, prevention and hygiene promotion through community education and hygiene training, and preparedness and response by strengthening disease monitoring, training Red Cross volunteers, and prepositioning medical supplies. This initiative, led by the Haitian and Dominican Red Cross in collaboration with international partners and local governments, aims to reduce cholera infections and improve public health on the island.

J Glob Health Sci. 2020 Jun;2(1):e3. A group of enzootic and zoonotic protozoan infections, the leishmaniases constitute among the most severely neglected tropical diseases (NTDs) and are found in all continents except Oceania. Representing the most common infectious diseases, NTDs comprise an open-...ended list of some 20 parasitic, bacterial, viral, protozoan and helminthic infections. Called “diseases of the poor,” because of their characteristic prevalence in poor populations regardless of a country's income status, they infect over one billion people in over 140 countries, with about 90% of the global burden in Africa. While NTDs do not contribute significantly to global deaths, they are debilitating and remain the most common infections among the poor worldwide, preventing them from escaping poverty by impacting livelihoods such as agriculture and livestock, and affecting cognitive, developmental and education outcomes.

Many African countries were amongst the most rapid to respond to the emerging threat of COVID-19, implementing large-scale interventions at very early stages of their epidemic. As demonstrated in this document using very simple models, this rapid mobilization and timeliness of implementing control m...easures is likely to be an important determinant of their success. Indeed, as these measures were relaxed, subsequent waves of disease have been observed in many countries including South Africa, Kenya, Tunisia, Morocco, Sudan and the Democratic Republic of Congo (DRC) where such waves have severely impacted the health system by straining the supply of oxygen and ICU beds and inflicting a heavy toll on healthcare workers, often necessitating the re-imposition of control measures.

This operational guidance on MHPSS provides a practical orientation and tools for UNHCR country operations. It covers specific points of good practice to consider when developing MHPSS programming and offers advice on priority issues and practical difficulties, while also providing some background i...nformation and definitions. Since MHPSS is a cross cutting concept this operational guidance is relevant for programming in various sectors, including health, community based protection, education, shelter, nutrition, food security and livelihoods.
The focus of this operational guidance is on refugees and asylum seekers, but it may apply to other persons of concern within UNHCR operations such as stateless persons, internally displaced persons and returnees. The guidance is meant for operations in both camp and non-camp settings, and in both rural and urban settings in low and middle-income countries with a UNHCR presence.
The guidance should be adapted according to different contexts. A standardized format for programme implementation cannot be offered because this depends to a large extent on existing national capacities and local opportunities.

As a lower-middle-income country (LMIC), South Africa (SA) bears
the burden of maternal and neonatal mortality similar to other sub-
Saharan African countries. According to the Saving Mothers Report
2017/19, there has been a progressive and sustained reduction
in institutional maternal mortality... (iMMR) in the past three triennia
(2010-2019), from 320 per 100,000 live births to 120 per 100,000 live
births.
According to the Rapid Mortality Survey, the country’s infant mortality
rate has declined from 29 deaths per 1000 live births in 2014 to 25
deaths per 1,000 live births in 2018. The institutional neonatal death
rate showed a slight decrease from 12,7 deaths per 1,000 live births in
2016 to the current level of 12 per 1,000 live births and has remained
static at this level for the past three years (saDHIS).
Working towards the Sustainable Development Goal (SDG) of reducing maternal mortality to below 70 per 100 000 live births and neonatal mortality to 12 deaths per 1000 live births, South Africa aims to reduce institutional maternal mortality, neonatal mortality and stillbirths by 50% by 2030.
This Maternal, Perinatal and Neonatal Health Policy provides a
framework for the delivery of quality, comprehensive, and integrated
MNH services and will guide the development and review of guidelines
and related MNH interventions, including strengthening of the service
delivery platform, governance, leadership and accountability for
the provision of quality MNH services, development of advocacy
messages, and guiding civil society priorities and community
initiatives. The policy will also guide the development and review of
academic curricula and the setting of research priorities.
