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.

Cardiovascular disease (CVD) is the leading cause of global deaths, with the majority occurring in low- and middle-income countries (LMIC). The primary and secondary prevention of CVD is suboptimal throughout the world, but the evidence-practice gaps are much more pronounced in LMIC. Barriers at the... patient, health-care provider, and health system level prevent the implementation of optimal primary and secondary prevention. Identification of the particular barriers that exist in resource-constrained settings is necessary to inform effective strategies to reduce the identified evidence-practice gaps. Furthermore, targeting modifiable factors that contribute most significantly to the global burden of CVD, including tobacco use, hypertension, and secondary prevention for CVD will lead to the biggest gains in mortality reduction. We review a select number of novel, resource-efficient strategies to reduce premature mortality from CVD, including: (1) effective measures for tobacco control; (2) implementation of simplified screening and management algorithms for those with or at risk of CVD, (3) increasing the availability and affordability of simplified and cost-effective treatment regimens including combination CVD preventive drug therapy, and (4) simplified delivery of health care through task-sharing (non-physician health workers) and optimizing self-management (treatment supporters). Developing and deploying systems of care that address barriers related to the above, will lead to substantial reductions in CVD and related mortality.

Updated Treatment Guidelines
Adolescent girls and young women (AGYW) remain disproportionately affected by HIV in Eastern and Southern Africa (ESA), with 26 per cent of new infections attributed to this population. AGYW face many personal, social and structural barriers to access, uptake and use of traditional HIV prevention me...thods. Oral Pre-exposure Prophylaxis (PrEP) is proven to be highly effective as an additional prevention choice for reducing the risk of HIV acquisition, including for AGYW. Successful uptake and adherence to PrEP is critical in its effectiveness as an HIV prevention method, however, the current demand for PrEP by AGYW is low with suboptimal adherence.
Within the ESA region, there is currently great impetus to address these challenges and scale up PrEP for AGYW. A critical aspect of this is to leverage the learnings and evidence from implementation of how to improve the demand and quality of PrEP programming for this population. Improving the Quality of Pre-Exposure Prophylaxis Implementation for Adolescent Girls and Young Women in Eastern and Southern Africa examines the current efforts in the region to accelerate and scale up evidence-based PrEP delivery platforms. The implementation brief provides current knowledge and builds on WHO guidance to provide key considerations for implementation, including driving demand and improving quality, as well as focus on wider combination prevention and integration agendas.

Sepsis contributes significantly to preventable mortality and is the final common pathway to death for severe infectious diseases; it can also arise as a complication of injuries and non-communicable diseases.
In Israel, as in other countries, the COVID-19 outbreak highlights existing structural inequities,which compromise the health of some migrant groups. The Israeli case also demonstrate show strong NGOs successfully advocate for the protection of migrants‘health amidst the crisis, madepossible bya c...ertain level ofcooperation withthe Israeli Ministry of Health.Hence,measures for COVID-19preparedness in Israel‘s marginalized migrant communities mostly result from pressure from civil society, against thebackdrop of a generally exclusionary approach toward migrants.4Over time, the Israeli Ministry of Health thus shifted from acknowledging the need to include migrants in preparedness measures toward the realization that particular needs and circumstances amongmigrant communities in some instances require special responses. Givena legacy of neglect and exclusion, this creates challenges for both the authorities and the migrant communities.
