Background
Cardiovascular diseases (CVDs) are one of the global leading causes of concern due to the rising prevalence and consequence of mortality and disability with a heavy economic burden. The objective of the current study was to analyze the trend in CVD incidence, mortality, and mortality-to-...incidence ratio (MIR) across the world over 28 years.
Methods
The age-standardized CVD mortality and incidence rates were retrieved from the Global Burden of Disease (GBD) Study 2017 for both genders and different world super regions with available data every year during the period 1990–2017. Additionally, the Human Development Index was sourced from the United Nations Development Programme (UNDP) database for all countries at the same time interval. The marginal modeling approach was implemented to evaluate the mean trend of CVD incidence, mortality, and MIR for 195 countries and separately for developing and developed countries and also clarify the relationship between the indices and Human Development Index (HDI) from 1990 to 2017.
Results
The obtained estimates identified that the global mean trend of CVD incidence had an ascending trend until 1996 followed by a descending trend after this year. Nearly all of the countries experienced a significant declining mortality trend from 1990 to 2017. Likewise, the global mean MIR rate had a significant trivial decrement trend with a gentle slope of 0.004 over the time interval. As such, the reduction in incidence and mortality rates for developed countries was significantly faster than developing counterparts in the period 1990–2017 (p < 0.05). Nevertheless, the developing nations had a more rather shallow decrease in MIR compared to developed ones.
Conclusions
Generally, the findings of this study revealed that there was an overall downward trend in CVD incidence and mortality rates, while the survival rate of CVD patients was rather stable. These results send a satisfactory message that global effort for controlling the CVD burden was quite successful. Nonetheless, there is an urgent need for more efforts to improve the survival rate of patients and lower the burden of this disease in some areas with an increasing trend of either incidence or mortality.

In 2015, the United Nations set important targets to reduce premature
cardiovascular disease (CVD) deaths by 33% by 2030. Africa disproportionately
bears the brunt of CVD burden and has one of the highest risks of dying
from non-communicable diseases (NCDs) worldwide. There is currently
an epide...miological transition on the continent, where NCDs is projected
to outpace communicable diseases within the current decade. Unchecked
increases in CVD risk factors have contributed to the growing burden of three
major CVDs—hypertension, cardiomyopathies, and atherosclerotic diseasesleading to devastating rates of stroke and heart failure. The highest age
standardized disability-adjusted life years (DALYs) due to hypertensive heart
disease (HHD) were recorded in Africa. The contributory causes of heart failure
are changing—whilst HHD and cardiomyopathies still dominate, ischemic
heart disease is rapidly becoming a significant contributor, whilst rheumatic
heart disease (RHD) has shown a gradual decline. In a continent where health
systems are traditionally geared toward addressing communicable diseases,
several gaps exist to adequately meet the growing demand imposed by CVDs.
Among these, high-quality research to inform interventions, underfunded
health systems with high out-of-pocket costs, limited accessibility and
affordability of essential medicines, CVD preventive services, and skill
shortages. Overall, the African continent progress toward a third reduction
in premature mortality come 2030 is lagging behind. More can be done in
the arena of effective policy implementation for risk factor reduction and
CVD prevention, increasing health financing and focusing on strengthening
primary health care services for prevention and treatment of CVDs, whilst
ensuring availability and affordability of quality medicines. Further, investing
in systematic country data collection and research outputs will improve the accuracy of the burden of disease data and inform policy adoption on
interventions. This review summarizes the current CVD burden, important
gaps in cardiovascular medicine in Africa, and further highlights priority
areas where efforts could be intensified in the next decade with potential
to improve the current rate of progress toward achieving a 33% reduction
in CVD mortality.

Global cardiovascular disease (CVD) burden is high and rising, especially in low-income and middle-income countries (LMICs). Focussing on 45 LMICs, we aimed to determine (1) the adult population’s median 10-year predicted CVD risk, including its variation within countries by socio-demographic char...acteristics, and (2) the prevalence of self-reported blood pressure (BP) medication use among those with and without an indication for such medication as per World Health Organization (WHO) guidelines.

Benchmarking is a strategic process often used by businesses and institutes to standardize performance in relation to the best practices of their sector. The World Health Organization (WHO) and partners have developed a tool with a list of benchmarks and corresponding suggested actions that can be a...pplied to implement the International Health Regulations 2005 (IHR) and strengthen health emergency prevention, preparedness, response and resilience capacities.
The first edition of the benchmarks was published in 2019 to support countries in developing, implementing and documenting progress of national IHR or health security plans (e.g. national action plan for health security (NAPHS), national action plan for emerging infectious diseases, public health emergencies and health security and other country level plans for health emergencies). The tool has been updated to incorporate lessons from COVID-19 and other health emergencies, to align with the updated IHR monitoring & evaluation framework (IHR MEF) tools and the health systems for health security framework, and to support strengthening health emergency prevention, preparedness, response and resilience (HEPR) capacities and the Preparedness and Resilience for Emerging Threats (PRET) initiative.

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.

Objective: To identify gaps in national stroke guidelines that could be bridged to enhance the quality of stroke care services in low- and
middle-income countries.
Methods: We systematically searched medical databases and websites of medical societies and contacted international organizations.
Co...untry-specific guidelines on care and control of stroke in any language published from 2010 to 2020 were eligible for inclusion. We reviewed
each included guideline for coverage of four key components of stroke services (surveillance, prevention, acute care and rehabilitation).
We also assessed compliance with the eight Institute of Medicine standards for clinical practice guidelines, the ease of implementation of
guidelines and plans for dissemination to target audiences.
Findings: We reviewed 108 eligible guidelines from 47 countries, including four low-income, 24 middle-income and 19 high-income countries.
Globally, fewer of the guidelines covered primary stroke prevention compared with other components of care, with none recommending
surveillance. Guidelines on stroke in low- and middle-income countries fell short of the required standards for guideline development;
breadth of target audience; coverage of the four components of stroke services; and adaptation to socioeconomic context. Fewer low- and
middle-income country guidelines demonstrated transparency than those from high-income countries. Less than a quarter of guidelines
encompassed detailed implementation plans and socioeconomic considerations.
Conclusion: Guidelines on stroke in low- and middle-income countries need to be developed in conjunction with a wider category of
health-care providers and stakeholders, with a full spectrum of translatable, context-appropriate interventions.

Objective: To conduct a landscape assessment of public knowledge of cardiovascular disease risk factors and acute myocardial infarction symptoms, cardiopulmonary resuscitation (CPR) and automated external defibrillator (AED) awareness and training in three underserved communities in Brazil.
Metho...ds: A cross-sectional, population-based survey of non-institutionalised adults age 30 or greater was conducted in three municipalities in Eastern Brazil. Data were analysed as survey-weighted percentages of the sampled populations.
Results: 3035 surveys were completed. Overall, one-third of respondents was unable to identify at least one cardiovascular disease risk factor and 25% unable to identify at least one myocardial infarction symptom. A minority of respondents had received training in CPR or were able to identify an AED. Low levels of education and low socioeconomic status were consistent predictors of lower knowledge levels of cardiovascular disease risk factors, acute coronary syndrome symptoms and CPR and AED use.
Conclusions: In three municipalities in Eastern Brazil, overall public knowledge of cardiovascular disease risk factors and symptoms, as well as knowledge of appropriate CPR and AED use was low. Our findings indicate the need for interventions to improve public knowledge and response to acute cardiovascular events in Brazil as a first step towards improving health outcomes in this population. Significant heterogeneity in knowledge seen across sites and socioeconomic strata indicates a need to appropriately target such interventions.

Background: Community health worker (CHW) programmes are a valuable component of primary care in resource-poor settings. The evidence supporting their effectiveness generally shows improvements in disease-specific outcomes relative to the absence of a CHW programme. In this study, we evaluated expan...ding an existing HIV and tuberculosis (TB) disease-specific CHW programme into a polyvalent, household-based model that subsequently included non-communicable diseases (NCDs), malnutrition and TB screening, as well as family planning and antenatal care (ANC).
Methods: We conducted a stepped-wedge cluster randomised controlled trial in Neno District, Malawi. Six clusters of approximately 20 000 residents were formed from the catchment areas of 11 healthcare facilities. The intervention roll-out was staggered every 3 months over 18 months, with CHWs receiving a 5-day foundational training for their new tasks and assigned 20–40 households for monthly (or more frequent) visits.
Findings: The intervention resulted in a decrease of approximately 20% in the rate of patients defaulting from chronic NCD care each month (−0.8 percentage points (pp) (95% credible interval: −2.5 to 0.5)) while maintaining the already low default rates for HIV patients (0.0 pp, 95% CI: −0.6 to 0.5). First trimester ANC attendance increased by approximately 30% (6.5pp (−0.3, 15.8)) and paediatric malnutrition case finding declined by 10% (−0.6 per 1000 (95% CI −2.5 to 0.8)). There were no changes in TB programme outcomes, potentially due to data challenges.

Alcohol use is deeply embedded in the social landscape of many societies, and some 2300 million people drink alcoholic beverages in most parts of the world. At the same time, more than half of the global population aged 15 years and older reported h...aving abstained from drinking alcohol during the previous 12 months. Several major factors have an impact on levels and patterns of alcohol consumption in populations – such as historical trends in alcohol consumption, the availability of alcohol, culture, economic status and implemented alcohol control measures. At the individual level the patterns and levels of alcohol consumption are determined by multiple factors that include gender, age and individual biological and socioeconomic vulnerability factors as well as the policy environment. Prevailing social norms that support drinking behaviour and mixed messages about the harms and benefits of drinking may encourage alcohol consumption, delay appropriate health-seeking behaviour and weaken community action.

The Government of Malawi is committed to improving health and livelihoods in Malawi through community health – the
provision of basic health services in rural and urban communities with the participation of people who live there.
Historically, Community Health has significantly contributed to im...provements in Malawi’s health outcomes in particular
attainment of MDG4. However, the community health system faces resource constraints and inconsistencies around quality
of service – which negatively affect health outcomes.

Background: Community Health Workers (CHWs) have a positive impact on the provision of community-based
primary health care through screening, treatment, referral, psychosocial support, and accompaniment. With a
broad scope of work, CHW programs must balance the breadth and depth of tasks to mainta...in CHW motivation for
high-quality care delivery. Few studies have described the CHW perspective on intrinsic and extrinsic motivation to
enhance their programmatic activities.
Methods: We utilized an exploratory qualitative study design with CHWs employed in the household model in Neno
District, Malawi, to explore their perspectives on intrinsic and extrinsic motivators and dissatisfiers in their work. Data
was collected in 8 focus group discussions with 90 CHWs in October 2018 and March–April 2019 in seven purposively
selected catchment areas. All interviews were audiotaped, transcribed verbatim, coded, and analyzed using Dedoose.
Results: Themes of complex intrinsic and extrinsic factors were generated from the perspectives of the CHWs in
the focus group discussions. Study results indicate that enabling factors are primarily intrinsic factors such as positive
patient outcomes, community respect, and recognition by the formal health care system but can lead to the chal-
lenge of increased scope and workload. Extrinsic factors can provide challenges, including an increased scope and
workload from original expectations, lack of resources to utilize in their work, and rugged geography. However, a posi-
tive work environment through supportive relationships between CHWs and supervisors enables the CHWs.
Conclusion: This study demonstrated enabling factors and challenges for CHW performance from their perspec-
tive within the dual-factor theory. We can mitigate challenges through focused efforts to limit geographical distance,
manage workload, and strengthen CHW support to reinforce their recognition and trust. Such programmatic empha-
sis can focus on enhancing motivational factors found in this study to improve the CHWs’ experience in their role. The
engagement of CHWs, the communities, and the formal health care system is critical to improving the care provided
to the patients and communities, along with building supportive systems to recognize the work done by CHWs for
the primary health care systems.

Evidence shows that oral pre-exposure prophylaxis (PrEP) reduces the risk of contracting HIV during sexual intercourse by more than 90% when taken daily. It is for this reason the National HIV Prevention Strategy 2015-2020 (2018 Revision) emphasises the role of preexposure prophylaxis (PrEP) in ...reducing new HIV infections in Malawi.
The Ministry of Health has prioritised PrEP use among the populations most at-risk of HIV infection in Malawi: young women ages 10 to 24 years, sero-discordant couples, female sex workers, men who have sex with men, and other priority populations (such as members of the uniformed services, prisoners, and mobile populations).
