Heart failure (HF) is a global public health concern with disproportionate socioeconomic, morbidity and mortality burden on low- and middle-income countries (LMICs). This review summarises contemporary data on the demographic and clinical characteristics, aetiologies, treatment, economic burden and ...outcomes of HF in LMICs. Patients with HF in LMICs are younger than those from high-income countries (HICs) and present at advanced stages of the disease. Hypertension, ischaemic heart disease (IHD), cardiomyopathy (CMO), and rheumatic heart disease (RHD) are the leading causes of HF in LMICs. The contribution of infectious diseases to HF remains prominent in many LMICs. Most health facilities in LMICs lack adequate diagnostic tools for HF, and the use of evidence-based medical and device therapies is suboptimal. Further, HF in LMICs is associated with prolonged hospital stay and high in-hospital and one-year mortality. Finally, HF has profound economic impact on individual patients who, mostly, have no health insurance, and on societies where patients are young, comprising those who have the greatest potential to contribute to economic productivity.

Introduction Community health workers (CHWs) are increasingly being tasked to prevent and manage cardiovascular disease (CVD) and its risk factors in underserved populations in low-income and middle-income countries (LMICs); however, little is known about the required training necessary for them to ...accomplish their role. This review aimed to evaluate the training of CHWs for the prevention and management of CVD and its risk factors in LMICs.
Methods A search strategy was developed in line with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, and five electronic databases (Medline, Global Health, ERIC, EMBASE and CINAHL) were searched to identify peer-reviewed studies published until December 2016 on the training of CHWs for prevention or control of CVD and its risk factors in LMICs. Study characteristics were extracted using a Microsoft Excel spreadsheet and quality assessed using Effective Public Health Practice Project’s Quality Assessment Tool. The search, data extraction and quality assessment were performed independently by two researchers.
Results The search generated 928 articles of which 8 were included in the review. One study was a randomised controlled trial, while the remaining were before–after intervention studies. The training methods included classroom lectures, interactive lessons, e-learning and online support and group discussions or a mix of two or more. All the studies showed improved knowledge level post-training, and two studies demonstrated knowledge retention 6 months after the intervention.
Conclusion The results of the eight included studies suggest that CHWs can be trained effectively for CVD prevention and management. However, the effectiveness of CHW trainings would likely vary depending on context given the differences between studies (eg, CHW demographics, settings and training programmes) and the weak quality of six of the eight studies. Well-conducted mixed-methods studies are needed to provide reliable evidence about the effectiveness and cost-effectiveness of training programmes for CHWs.

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.

To assess the quality of Indian clinical practice guidelines (CPG)s for the management of cardiovascular conditions, MEDLINE, Embase, Google Scholar and websites of relevant medical associations and government organisations were searched, from inception until August 2020, to identify Indian CPGs for... the management of cardiovascular disease (CVD) conditions, produced in or between 2010 and 2019. Excluded were CPGs that were not specific to India, focused on alternative systems of medicine, of non-CVD conditions (even if they included a component of CVD), and those related to the electronic devices, cardiac biomarkers, or diagnostic procedures. Quality of the each included CPG was assessed using the AGREE II tool by four reviewers in duplicate, independently. Each AGREE II domain score and overall quality score was considered low (≤40%), moderate (40.1%-59.9%), and high (≥60%). Of the 23 CPGs included, six (26%) were reported to be adapted from other CPGs. Fourteen (61%) CPGs were produced by medical associations, six (26%) by individual authors and three (13%) by government agencies. Based on the AGREE II overall quality score, two (9%) CPGs were of high quality, four (17%) and seventeen (74%) CPGs were of moderate and low quality, respectively. Except for scope and purpose, and clarity of presentation all other domains were rated low. The quality of most Indian CPGs for managing CVD conditions assessed using the AGREE II tool was moderate-to-low. Combined efforts from different stakeholders are needed to develop, disseminate and implement high-quality CPGs while identifying and addressing barriers to their uptake to optimize patient care and improve outcomes.

Diabetic foot ulcers are a complication affecting approximately 15% of the total population with diabetes mellitus. There are three and half million diabetic patients in Saudi Arabia alone. Aim: to determine capacity building for nurses’ knowledge and practice regarding prevention of diabetic foot... complications. Research Questions: 1. Does the nurse’s knowledge prevent diabetic foot ulcer and other foot complications? 2. Does the high practice of the nurses during foot screening can prevent diabetic foot ulcer in primary health care centers in Saudi Arabia? Design: Descriptive, research designs have been utilized. Setting: Chronic disease clinic in primary health care centers in Jeddah city. Subjects: a purposive sample of 30 nurses and convenience sample of 30 patients. Tools: A. Diabetic foot ulcer Structured interview questionnaire to assess nurse’s knowledge regarding diabetes mellitus and diabetic foot. B. Health status assessment questionnaire to assess health history status of diabetic client. C. An observational checklist to assess the nurse practice once during diabetic foot screening. Results: Significant increase in nurse's knowledge had been observed, while the majority of them had poor practice in relation to foot screening. Whereas complicated diabetic patients represent 35.7% of diabetic patients have neuropathy. Moreover, only 7.1% have neuropathy and diabetic ketoacidosis. Also there was a significant moderate positive correlation between the overall score of nurse’s knowledge and the overall score of the practice regarding diabetic foot complications. Conclusions: Proper foot care, early recognition and management of risk factors prevent foot ulcer. Recommendations: Developing a structured training educational program for nurses dealing patients with diabetic foot disorders.

Existing data on chronic obstructive pulmonary disease (COPD) prevalence are irregularly distributed around the world, and in many geographic regions data are scarce or even nonexistent. This fact hinders the implementation of adequate preventive and therapeutic interventions to reduce the high burd...en and costs of COPD. In the current study, we have used the Geographic Information System (GIS) inverse distance weighted (IDW) interpolation technique with the objective of visualising spatial data of COPD prevalence in the world and obtaining a visual impression of the magnitude of this global health problem. GIS has been recognised as an effective tool to display the geographical distribution of data, even when they are few and widely separated, as is the case with the prevalence of COPD.

Silicosis is not a new disease; the impact of silica dust on respiratory function was observed by Hippocrates in 430 B.C. and in the 16th century by Agricol. In 1713, Rammazini described silicotic nodules in post-mortems of stone cutters presenting with respiratory symptoms. In the mid-late 1800s,... the introduction of mechanized tools in the mining sector rapidly increased levels of silica exposure, resulting in an increase in cases and our understanding of silicosis.
