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.

This study aimed to analyze the geographical distribution of coronavirus disease 2019 (COVID-19) and to identify high-risk areas in space and time for the occurrence of cases and deaths in the indigenous population of Brazil. This is an ecological study carried out between 24 March and 26 October 20...20 whose units of analysis were the Special Indigenous Sanitary Districts. The Getis-Ord General G and Getis-Ord Gi* techniques were used to verify the spatial association of the phenomena and a retrospective space–time scan was performed. There were 32 041 confirmed cases of COVID-19 and 471 deaths. The non-randomness of cases (z score = 5.40; P < 0.001) and deaths (z score = 3.83; P < 0.001) were confirmed. Hotspots were identified for cases and deaths in the north and midwest regions of Brazil. Sixteen high-risk space–time clusters were identified for the occurrence of cases with a higher RR = 21.23 (P < 0.001) and four risk clusters for deaths with a higher RR = 80.33 (P < 0.001). These clusters were identified from 22 May and were active until 10 October 2020. The results indicate critical areas in the indigenous territories of Brazil and contribute to better directing the actions of control of COVID-19 in this population.

Internationally, there is a growing concern over antimicro-bial resistance (AMR) which is currently estimated to ac-count for more than 700,000 deaths per year worldwide. If no appropriate measures are taken to halt its pro-gress, AMR will cost approximately 10 million lives andabout US$100 trillion... per year by 2050. In contrast tosome other health issues, AMR is a problem that con-cerns every country irrespective of its level of incomeand development as resistant pathogens do not respect borders.Despite the threat presented by AMR, the 2014 WorldHealth Organization (WHO) and the recent O’Neill re-port describe significant gaps in surveillance, standardmethodologies and data sharing. The 2014 WHOreport identified Africa and South East Asia as the regions without established AMR surveillance systems.

The article is a scoping review that explores the challenges in diagnosing asthma in children in three sub-Saharan African countries: Nigeria, South Africa, and Uganda. It identifies key barriers, such as a lack of community awareness, inadequate healthcare access, limited diagnostic tools like spir...ometry, and insufficient knowledge among healthcare workers. The review also highlights the stigma associated with asthma and the absence of relevant diagnostic guidelines. Solutions proposed include community education, development and adherence to diagnostic guidelines, and strengthening healthcare systems. The study aims to inform policymakers and healthcare providers to improve asthma diagnosis and care for children in these regions.

This perspective draws on the record of ancient pathogengenomes and microbiomes illuminating patterns of infectious disease over the course of the Holocene in order toaddress the following question. How did major changes inliving circumstances involving the transition to and intensification of farmi...ng alter pathogens and their distributions? Answers to this question via ancient DNA researchprovide a rapidly expanding picture of pathogen evolution and in concert with archaeological and historical data, give a temporal and behavioral context for heath in the past that is relevant for challenges facing the world today, including the rise of novel pathogens.

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.

BMJ Global Health, Vol.5 No. 12Spatial subdivision of the camp (‘sectoring’) was able to ‘flatten the curve’, reducing peak infection by up to 70% and delaying peak infection by up to several months. The use of face masks coupled with the efficient isolation of infected individuals reduced t...he overall incidence of infection, and sometimes averted epidemics altogether. These interventions must be implemented quickly in order to be maximally effective. Lockdowns had only small effects on COVID-19 dynamics.
Conclusions
Agent-based models are powerful tools for forecasting the spread of disease in spatially structured and heterogeneous populations. Our findings suggest that feasible interventions can slow the spread of COVID-19 in a refugee camp setting, and provide an evidence base for camp managers planning intervention strategies. Our model can be modified to study other closed populations at risk from COVID-19 or future epidemics.

The document addresses the pressing issues of global malnutrition and the urgent need to build workforce capacity in public health nutrition, particularly in low- and middle-income countries. It highlights the dual burden of malnutrition, characterized by the coexistence of undernutrition and overnu...trition. While maternal and child undernutrition remain critical concerns, there is a growing prevalence of chronic diseases linked to overnutrition, even in resource-limited settings.
A significant gap exists in the availability of trained nutrition professionals. Many countries lack sufficient numbers of nutritionists, particularly at the undergraduate level, and existing training programs often focus on curative rather than preventive approaches. This leaves health workers inadequately prepared to address complex public health nutrition challenges.
To address these issues, the document recommends increasing the number of trained nutritionists, incorporating updated nutrition training into medical and nursing curricula, and developing competency frameworks and hybrid training programs. Accreditation systems for nutrition professionals are also proposed to ensure standardized and effective training.
Sustainability remains a challenge, with the need for long-term financing and better integration of nutrition programs into health systems. The document calls for systemic approaches to strengthen workforce capacity, enabling countries to effectively tackle the underlying causes of malnutrition.

Chronic manifestations of Chagas disease present as disabling and life-threatening conditions affecting mainly the cardiovascular and gastrointestinal systems. Although meaningful research has outlined the different molecular mechanisms underlying Trypanosoma cruzi’s infection and the host-parasit...e interactions that follow, prompt diagnosis and treatment remain a challenge, particularly in developing countries and also in those where the disease is considered non-endemic. This review intends to present an up-to-date review of the parasite’s life cycle, genetic diversity, virulence
factors, and infective mechanisms, as well as the epidemiology, clinical presentation, diagnosis, and treatment options of the main chronic complications of Chagas disease.

South Sudan has a high burden – among the highest in sub-Saharan Africa – of neglected tropical diseases (NTDs). This adversely affects the health and social and economic well-being of people in the country. The prevention, control and eventual elimination of many NTDs depend heavily on improved... access to water, sanitation and hygiene (WASH) and, once there is access, on sound sanitation and hygiene practices. This is especially the case in NTD endemic communities.
The main NTDs prevalent in South Sudan include lymphatic filariasis, schistosomiasis (bilharzia), soiltransmitted helminths (STH), onchocerciasis, trachoma, leishmaniasis and Guinea-worm disease.
While the Ministry of Health (MoH) of South Sudan, through its NTD programme, had prioritized NTD/WASH partnerships and collaboration to improve the national NTD response, the programme lacked resources, capacity and a technical framework to lead the development of a harmonized NTD/WASH communication strategy.
