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 physi...cal activity occurs may promote physical activity at 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 is a major cause of disability and premature death throughout the world, and contributes substantially to the escalating costs of health care. The underlying pathology is atherosclerosis, which develops over many years and is ...usually advanced by the time symptoms occur, generally in middle age. Acute coronary and cerebrovascular events frequently occur suddenly, and are often fatal before medical care can be given. Modification of risk factors has been shown to reduce mortality and morbidity in people with diagnosed or undiagnosed cardiovascular disease.
This publication provides guidance on reducing disability and premature deaths from coronary heart disease, cerebrovascular disease and peripheral vascular disease in people at high risk, who have not yet experienced a cardiovascular event. People with established cardiovascular disease are at very high risk of recurrent events and are not the subject of these guidelines. They have been addressed in previous WHO guidelines.
Several forms of therapy can prevent coronary, cerebral and peripheral vascular events. Decisions about whether to initiate specific preventive action, and with what degree of intensity, should be guided by estimation of the risk of any such vascular event. The risk prediction charts that accompany these guidelinesb allow treatment to be targeted accord-
ing to simple predictions of absolute cardiovascular risk.
Recommendations are made for management of major cardiovascular risk factors through changes in lifestyle and prophylactic drug therapies. The guidelines provide a framework for the development of national guidance on prevention of cardiovascular disease that takes into account the particular political, economic, social and medical circumstances.

In recent years, Rwanda has been on the fast track to achieve major health improvements for its entire population. With the support of government agencies and various non-governmental partners, the Ministry of Health (MoH) has endeavored to decentra...lize Rwanda’s health system and bring health services closer to the people. Guided by multitude of national and international development frameworks, Rwanda’s healthcare successes include the establishment of a community health insurance scheme (mutuelle de santé), a system of cooperative-financed community health workers in every village, and interventions for researching, preventing, and treating diseases like HIV/AIDS, TB, and malaria.
As the MoH continues to design innovative means to reach and surpass its prescribed health outcome targets, it will hold as core principles the integration of service provision, the increase in healthcare capacity, and the attainment of sustainable funding sources. Rwanda is committed to achieving the Millennium Development Goals by 2015 and has declared Family Planning (FP) a national priority for poverty reduction and socioeconomic development of the country. Modern contraceptive use has more than quadrupled from 2005 to 2010, rising from 10% to 45%, but the government’s Economic Development and Poverty Reduction Strategy calls for an increase the modern contraceptive prevalence to 70% by 2016. While structural changes in health care and supply chains have led to noteworthy improvements in FP and other services, there are still many challenges that must be overcome. As such, a strategic plan is needed to coordinate FP efforts around a well-defined set of objectives and responsibilities.

The Covid-19 pandemic has so far infected more than 30 million people in the world, having major impact on global health with collateral damage. In Mozambique, a public state of emergency was declared at the end of March 2020. This has limited peopl...e's movements and reduced public services, leading to a decrease in the number of people accessing health care facilities. An implementation research project, The Alert Community for a Prepared Hospital, has been promoting access to maternal and child health care, in Natikiri, Nampula, for the last four years. Nampula has the second highest incidence of Covid-19. The purpose of this study is to assess the impact of Covid-19 pandemic Government restrictions on access to maternal and child healthcare services. We compared health centres in Nampula city with healthcare centres in our research catchment area. We wanted to see if our previous research interventions have led to a more resilient response from the community.
METHODS: Mixed-methods research, descriptive, cross-sectional, retrospective, using a review of patient visit documentation. We compared maternal and child health care unit statistical indicators from March-May 2019 to the same time-period in 2020. We tested for significant changes in access to maternal and child health services, using KrushKall Wallis, One-way Anova and mean and standard deviation tests. We compared interviews with health professionals, traditional birth attendants and patients in the two areas. We gathered data from a comparable city health centre and the main city referral hospital. The Marrere health centre and Marrere General Hospital were the two Alert Community for a Prepared Hospital intervention sites.
RESULTS: Comparing 2019 quantitative maternal health services access indicators with those from 2020, showed decreases in most important indicators: family planning visits and elective C-sections dropped 28%; first antenatal visit occurring in the first trimester dropped 26%; hospital deliveries dropped a statistically significant 4% (p = 0.046), while home deliveries rose 74%; children vaccinated down 20%.
CONCLUSION: Our results demonstrated the negative collateral effects of Covid-19 pandemic Government restrictions, on access to maternal and child healthcare services, and highlighted the need to improve the health information system in Mozambique.

In 2007, WHO warned that infectious diseases are emerging and re-emerging at a rate that has not been seen before. The potential for infectious diseases to spread rapidly results in high morbidity and mortality, causing a potential global public health treat of ...dbox">major concern.
Several factors are contributing to the (re)emergence of infectious diseases such as population growth, living in close contact with animals, frequent travelling, poverty, destructive ecological changes due to economic development and land use and climate change result in global warming.
Especially Africa is at a threat for (re)emerging infectious diseases due to the huge population growth (expected to reach 2.5 billion by 2050) with rapid urbanisation. Additionally, people across and beyond the continent are excessively mobile which is combined with a weak health system. Moreover, the risk of (re)emerging infectious disease is further heightened by three newly adopted continental initiatives: African Continental Free Trade Area, Free Movement of Persons and African Passport and Single African Air Transport Market.

Neglected tropical diseases (NTDs) is an umbrella term for a diverse group of debilitating infections that represent the most common afflictions for 2.7 billion people living on less than US$2 per day. Major efforts have recently re-focused attentio...n on NTDs, including structured advocacy by the Bill and Melinda Gates Foundation, technical and political support by WHO and large-scale drug donation programs by pharmaceutical companies. An analysis of the Official Development Assistance (ODA) for NTDs in 2009 showed that Development Assistance Committee members and multilateral donors had largely ignored funding NTD control projects. This study reviews the changes since 2009 and finds an increased engagement by pharmaceutical manufacturers through drug donation programs substantially increased by the ‘London Declaration’ in 2012, a focused effort of 77 public and private partners on control or elimination of the 10 most common NTDs, but no increase in ODA for NTDs between 2008 and 2012. The allocation of ODA still does not reflect the respective importance of these diseases.

The pharmacological treatment of heart failure has evolved over the last three decades since the demonstration of the effect of angiotensinconverting enzyme inhibitors on major cardiovascular events in patients with heart failure with reduced ejecti...on fraction. Composite analysis of heart failure with reduced ejection fraction trials and the recent identification of newer drug treatments show early benefits on the major cardiovascular outcomes, ushering in a change of the treatment strategy; from a ‘sequential’ initiation of the treatments to a ‘simultaneous’ initiation to harness the early benefits. The adoption and implementation of these changes at the bedside have been dismal in many healthcare settings. Papua New Guinea, like many other lower-to-middle-income countries, is facing many barriers that impact on the care of heart failure patients. It needs to adopt and implement these changes to provide evidence-based treatment for its people with heart failure with reduced ejection fraction.

It emphasizes that hypertension is a major cause of premature de...ath worldwide, with an estimated 1.28 billion adults aged 30–79 years affected, two-thirds of whom live in low- and middle-income countries.
The document outlines modifiable risk factors, including unhealthy diets, physical inactivity, tobacco and alcohol use, and being overweight or obese. It also discusses non-modifiable risk factors such as family history, age over 65 years, and co-existing conditions like diabetes or kidney disease. The fact sheet underscores the importance of regular blood pressure monitoring, as hypertension often presents without symptoms, and highlights lifestyle changes and medications as effective treatments. Additionally, it mentions global targets aimed at reducing the prevalence of hypertension by 33% between 2010 and 2030.

The challenges include the rapid transformation in communications technology, including the near-universal penetration of mobile telephones, the widespread use and increasingly powerful influence of digital media which has had an impact on ‘traditional’ media (newspapers, radio and television), and major changes in how people access and trust health information. Important gaps include considerations of context – the social, economic, political and cultural factors influencing people’s perception of risk and their risk-reduction behaviours.

An IPCC special report on climate change, desertification, land degradation, sustainable land management, food security, and greenhouse gas fluxes in terrestrial ecosystems
As more frequent droughts and floods threaten the global food supply, humans are increasing their demands on water and land,... The New York Times reports.
Data from the Intergovernmental Panel on Climate Change report:
• 500 million people are living in areas that are becoming desert.
• Soil is depleted at 10X-100X the rate it’s being formed.
• More than 10% of the global population is undernourished.
Major threats include the risk of “multi-breadbasket failure”—simultaneous food crises on several continents—and migration triggered by food shortages.
Good News/Bad News: Catastrophe can be avoided, but it would require massive changes to agriculture, food systems and behavior.
A Key Action: Eat less meat. Cattle production is driving deforestation, consuming huge amounts of water, generating methane and causing other impacts, notes Nature.
