Dracunculiasis (Guinea worm disease), caused by the parasite Dracunculus medinensis, is traditionally acquired by drinking water containing copepods (water fleas) infected with D. medinensis larvae, but in recent years also appears increasingly to be transmitted by eating fish or other aquatic anima...ls. The worm typically emerges through the skin on a lower limb of the host 1 year after infection, causing pain and disability.

As a high-burden neglected tropical disease, soil-transmitted helminth (STH) infections remain a major problem in the world, especially among children under five years of age. Since young children are at high risk of being infected, STH infection can have a long-term negative impact on their life, i...ncluding impaired growth and development. Stunting, a form of malnutrition in young children, has been long assumed as one of the risk factors in acquiring the STH infections. However, the studies on STH infection in children under five with stunting have been lacking, resulting in poor identification of the risk. Accordingly, we collected and reviewed existing related research articles to provide an overview of STH infection in a susceptible population of stunted children under five years of age in terms of prevalence and risk factors. There were 17 studies included in this review related to infection with Ascaris lumbricoides, Trichuris trichiura, hookworm, and Strongyloides stercoralis from various countries. The prevalence of STH infection in stunted children ranged from 12.5% to 56.5%. Increased inflammatory markers and intestinal microbiota dysbiosis might have increased the intensity of STH infection in stunted children that caused impairment in the immune system. While the age from 2 to 5 years along with poor hygiene and sanitation has shown to be the most common risk factors of STH infections in stunted children; currently there are no studies that show direct results of stunting as a risk factor for STH infection. While stunting itself may affect the pathogenesis of STH infection, further research on stunting as a risk factor for STH infection is encouraged.

The Sustainable Development Goals (SDGs) call for major societal transformations that will require significant fiscal outlays as well as private investments. The fiscal outlays cover public investments, the public provision of social services, and social protection for vulnerable populations. The ke...y message of this paper, building on recent reports by the IMF and SDSN (IMF, 2019b; SDSN, 2018) is that the governments of Low-Income Developing Countries (LIDCs) will require a substantial increase in fiscal (budget) revenues, far beyond what they can achieve by their own fiscal reforms. For this reason, SDG financing will require substantial international cooperation to enable the LIDCs to finance their SDG fiscal outlays. One important source of increased revenues should be the globally coordinated taxation of ultra-high-net worth assets. Today’s ultra-rich should help to pay for the survival and basic needs of the world’s poorest people.

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.

Heart failure with a reduced ejection fraction (HFrEF) is a condition frequently encountered by healthcare professionals and, in order to achieve the best outcomes for patients, needs to be managed optimally. This guideline document is based on the European Society of Cardiology Guidelines for the t...reatment of acute and chronic heart failure published in 2016, and summarises what is considered the best current management of patients with the condition. It provides information on the definition, diagnosis and epidemiology of HFrEF in the African context. The best evidence-based treatments for HFrEF are discussed, including established therapies (beta-blockers, ACE-i/ARBs, mineralocorticoid receptor antagonists (MRAs), diuretics) that form the cornerstone of heart failure management as well as therapies that have only recently entered clinical use (angiotensin receptor-neprilysin inhibitor (ARNI), sodium/glucose cotransporter-2 (SGLT2) inhibitors). Guidance is offered in terms of more invasive therapies (revascularisation, implantable cardioverter defibrillators (ICDs) and cardiac resynchronisation therapy (CRT) by implantation of a biventricular pacemaker with (CRT-D) or without (CRT-P) an ICD, left ventricular assist device (LVAD) use and heart transplantation) in order to ensure efficient use of these expensive treatment modalities in a resourcelimited environment. Furthermore, additional therapies (digoxin, hydralazine and nitrates, ivabradine, iron supplementation) are discussed and advice is provided on general preventive strategies (vaccinations). Sections to discuss conditions that are particularly prevalent in sub-Saharan Africa (HIV-associated cardiomyopathy (CMO), peripartum CMO, rheumatic heart disease, atrial fibrillation) have been added to further improve clinical care for these commonly encountered disease processes.

ABSTRACT
More than 500 million people worldwide live with cardiovascular disease (CVD). Health systems today face fundamental challenges in delivering optimal care due to ageing populations, healthcare workforce constraints, financing, availability and affordability of CVD medicine, and service del...ivery.
Digital health technologies can help address these challenges. They may be a tool
to reach Sustainable Development Goal 3.4 and reduce premature mortality from
non-communicable diseases (NCDs) by a third by 2030. Yet, a range of fundamental barriers prevents implementation and access to such technologies. Health system governance, health provider, patient and technological factors can prevent or distort their implementation.
World Heart Federation (WHF) roadmaps aim to identify essential roadblocks on the pathway to effective prevention, detection, and treatment of CVD. Further, they aim to provide actionable solutions and implementation frameworks for local adaptation. This WHF Roadmap for digital health in cardiology identifies barriers to implementing digital health technologies for CVD and provides recommendations for overcoming them.

In 2012, all Member States of the World Health Organization (WHO) endorsed a historical target to reduce premature mortality from noncommunicable diseases
(NCD). This commitment was echoed in 2015 by the United Nations Sustainable Development Goals, which included a target to reduce premature morta...lity (the
measure of unfulfilled life expectancy and deaths between the ages of 30 and 70 years) from NCD by 30% by the year 2030. The Sustainable Development Goals are especially relevant to cardiovascular disease (CVD), the leading cause of death globally, with increasing prevalence in low- and middle-income countries (LMIC).

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.

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.

Approximately 80% of the 463 million adults worldwide with diabetes live in low-income and middle-income countries (LMICs). A major obstacle to designing evidence-based policies to improve diabetes outcomes in LMICs is the scarce availability of nationally representative data on the current patterns... of treatment coverage. The objectives of this study were to estimate the proportion of adults with diabetes in LMICs who receive coverage of recommended pharmacological and non-pharmacological diabetes treatment; and to describe country-level and individual-level characteristics that are associated with treatment.

Asthma is the most common non-communicable disease in children and remains one of the most common throughout the life course. The great majority of the burden of this disease is seen in low-income and middle-income countries (LMICs), which have disproportionately high asthma-related mortality relati...ve to asthma prevalence. This is particularly true for many countries in sub-Saharan Africa. Although inhaled asthma treatments (particularly those containing inhaled corticosteroids) markedly reduce asthma morbidity and mortality, a substantial proportion of the children, adolescents, and adults with asthma in LMICs do not get to benefit from these, due to poor availability and affordability. In this review, we consider the reality faced by clinicians managing asthma in the primary and secondary care in sub-Saharan Africa and suggest how we might go about making diagnosis and treatment decisions in a range of resource-constrained scenarios. We also provide recommendations for research and policy, to help bridge the gap between current practice in sub-Saharan Africa and Global Initiative for Asthma (GINA) recommended diagnostic processes and treatment for children, adolescents, and adults with asthma.
