Projected burden and distribution of elevated blood pressure levels and its consequence among adolescents in sub-Saharan Africa.

Background: There is minimal data on the number of adolescents in sub-Saharan Africa (SSA) with elevated blood pressure (BP) at increased risk of future cardiovascular events. Combining country-specific population data with data derived from two previously conducted meta-analyses (one African-specific, one based on international cohorts), we sought to address this knowledge deficit. Methods: We used meta-analysis data from 37 926 adolescents participating in 36 contemporary SSA studies to generate sex-specific proportions of adolescents aged 10-14 and 15-19 years with elevated BP. The estimates were applied to the 2021 World Bank population data for each country in SSA. We then applied the rate of cardiovascular events attributable to elevated BP levels, derived from a meta-analysis of 17 observational, longitudinal cohort studies comprising 4.5 million young adults (non-African), to determine the excess number of cardiovascular events linked to hypertension among those aged 15-19 years transitioning to adulthood. Results: The estimated prevalence of elevated BP among male and female adolescents aged 10-14 years living in SSA was 7.2% (95% confidence interval (CI) = 4.9-9.9) and 6.9% (95% CI = 4.7-9.5), respectively, which increased to 13.0% (95% CI = 10.6-15.6) and 12.5% (95% CI = 10.4-15.3) among male and female adolescents aged 15-19 years, respectively. Consequently, we estimate that 13.6/138.0 million (95% CI = 10.4-17.3) male and 12.9/135.7 million (95% CI = 9.83-16.3) female adolescents living in SSA have elevated BP. Among the estimated 16.1 million adolescents aged 15-19 years with elevated BP approaching adulthood, the projected excess in cardiovascular events attributable to hypertension (vs normotension) is 201 000 (95% CI = 115 000-322 000) to 503 000 (95% CI = 286 000-805 000) over the next 10-25 years. Conclusions: Based on the best available data, we estimate that 26.5 million adolescents living in SSA have elevated BP. If left undetected and untreated among those approaching adulthood (those aged 15-19 years), they will experience >0.5 million excess cardiovascular events associated with persistently elevated BP within the next 25 years.

Realigning noncommunicable disease monitoring with health systems priorities in the Africa region.

The African region of the World Health Organization (WHO) recently adopted a strategy aimed at more comprehensive care for noncommunicable diseases (NCDs) in the region. The WHO's World Health Assembly has also newly approved several ambitious disease-specific targets that raise the expectations of chronic care and plans to revise and update the NCD-Global Action Plan. These actions provide a critically needed opportunity for reflection and course correction in the global health response to NCDs. In this paper, we highlight the status of the indicators that are currently used to monitor progress towards global goals for chronic care. We argue that weak health systems and lack of access to basic NCD medicines and technologies have prevented many countries from achieving the level of progress required by the NCD epidemic, and current targets do little to address this reality. We identify gaps in existing metrics and explore opportunities to realign the targets with the pressing priorities facing today's health systems.

Prioritizing Health-Sector Interventions for Noncommunicable Diseases and Injuries in Low- and Lower-Middle Income Countries: National NCDI Poverty Commissions.

Health sector priorities and interventions to prevent and manage noncommunicable diseases and injuries (NCDIs) in low- and lower-middle-income countries (LLMICs) have primarily adopted elements of the World Health Organization Global Action Plan for NCDs 2013-2020. However, there have been limited efforts in LLMICs to prioritize among conditions and health-sector interventions for NCDIs based on local epidemiology and contextually relevant risk factors or that incorporate the equitable distribution of health outcomes. The Lancet Commission on Reframing Noncommunicable Diseases and Injuries for the Poorest Billion supported national NCDI Poverty Commissions to define local NCDI epidemiology, determine an expanded set of priority NCDI conditions, and recommend cost-effective, equitable health-sector interventions. Fifteen national commissions and 1 state-level commission were established from 2016-2019. Six commissions completed the prioritization exercise and selected an average of 25 NCDI conditions; 15 conditions were selected by all commissions, including asthma, breast cancer, cervical cancer, diabetes mellitus type 1 and 2, epilepsy, hypertensive heart disease, intracerebral hemorrhage, ischemic heart disease, ischemic stroke, major depressive disorder, motor vehicle road injuries, rheumatic heart disease, sickle cell disorders, and subarachnoid hemorrhage. The commissions prioritized an average of 35 health-sector interventions based on cost-effectiveness, financial risk protection, and equity-enhancing rankings. The prioritized interventions were estimated to cost an additional US$4.70-US$13.70 per capita or approximately 9.7%-35.6% of current total health expenditure (0.6%-4.0% of current gross domestic product). Semistructured surveys and qualitative interviews of commission representatives demonstrated positive outcomes in several thematic areas, including understanding NCDIs of poverty, informing national planning and implementation of NCDI health-sector interventions, and improving governance and coordination for NCDIs. Overall, national NCDI Poverty Commissions provided a platform for evidence-based, locally driven determination of priorities within NCDIs.

Burden of disease among the world's poorest billion people: An expert-informed secondary analysis of Global Burden of Disease estimates.

BACKGROUND: The health of populations living in extreme poverty has been a long-standing focus of global development efforts, and continues to be a priority during the Sustainable Development Goal era. However, there has not been a systematic attempt to quantify the magnitude and causes of the burden in this specific population for almost two decades. We estimated disease rates by cause for the world's poorest billion and compared these rates to those in high-income populations. METHODS: We defined the population in extreme poverty using a multidimensional poverty index. We used national-level disease burden estimates from the 2017 Global Burden of Disease Study and adjusted these to account for within-country variation in rates. To adjust for within-country variation, we looked to the relationship between rates of extreme poverty and disease rates across countries. In our main modeling approach, we used these relationships when there was consistency with expert opinion from a survey we conducted of disease experts regarding the associations between household poverty and the incidence and fatality of conditions. Otherwise, no within-country variation was assumed. We compared results across multiple approaches for estimating the burden in the poorest billion, including aggregating national-level burden from the countries with the highest poverty rates. We examined the composition of the estimated disease burden among the poorest billion and made comparisons with estimates for high-income countries. RESULTS: The composition of disease burden among the poorest billion, as measured by disability-adjusted life years (DALYs), was 65% communicable, maternal, neonatal, and nutritional (CMNN) diseases, 29% non-communicable diseases (NCDs), and 6% injuries. Age-standardized DALY rates from NCDs were 44% higher in the poorest billion (23,583 DALYs per 100,000) compared to high-income regions (16,344 DALYs per 100,000). Age-standardized DALY rates were 2,147% higher for CMNN conditions (32,334 DALYs per 100,000) and 86% higher for injuries (4,182 DALYs per 100,000) in the poorest billion, compared to high-income regions. CONCLUSION: The disease burden among the poorest people globally compared to that in high income countries is highly influenced by demographics as well as large disparities in burden from many conditions. The comparisons show that the largest disparities remain in communicable, maternal, neonatal, and nutritional diseases, though NCDs and injuries are an important part of the "unfinished agenda" of poor health among those living in extreme poverty.

An investment case for the prevention and management of rheumatic heart disease in the African Union 2021-30: a modelling study.

BACKGROUND: Despite declines in deaths from rheumatic heart disease (RHD) in Africa over the past 30 years, it remains a major cause of cardiovascular morbidity and mortality on the continent. We present an investment case for interventions to prevent and manage RHD in the African Union (AU). METHODS: We created a cohort state-transition model to estimate key outcomes in the disease process, including cases of pharyngitis from group A streptococcus, episodes of acute rheumatic fever (ARF), cases of RHD, heart failure, and deaths. With this model, we estimated the impact of scaling up interventions using estimates of effect sizes from published studies. We estimated the cost to scale up coverage of interventions and summarised the benefits by monetising health gains estimated in the model using a full income approach. Costs and benefits were compared using the benefit-cost ratio and the net benefits with discounted costs and benefits. FINDINGS: Operationally achievable levels of scale-up of interventions along the disease spectrum, including primary prevention, secondary prevention, platforms for management of heart failure, and heart valve surgery could avert 74 000 (UI 50 000-104 000) deaths from RHD and ARF from 2021 to 2030 in the AU, reaching a 30·7% (21·6-39·0) reduction in the age-standardised death rate from RHD in 2030, compared with no increase in coverage of interventions. The estimated benefit-cost ratio for plausible scale-up of secondary prevention and secondary and tertiary care interventions was 4·7 (2·9-6·3) with a net benefit of $2·8 billion (1·6-3·9; 2019 US$) through 2030. The estimated benefit-cost ratio for primary prevention scale-up was low to 2030 (0·2, <0·1-0·4), increasing with delayed benefits accrued to 2090. The benefit-cost dynamics of primary prevention were sensitive to the costs of different delivery approaches, uncertain epidemiological parameters regarding group A streptococcal pharyngitis and ARF, assumptions about long-term demographic and economic trends, and discounting. INTERPRETATION: Increased coverage of interventions to control and manage RHD could accelerate progress towards eradication in AU member states. Gaps in local epidemiological data and particular components of the disease process create uncertainty around the level of benefits. In the short term, costs of secondary prevention and secondary and tertiary care for RHD are lower than for primary prevention, and benefits accrue earlier.

Design and Implementation of Postgraduate Programs in Health in a Resource-Limited Setting in Mozambique (The Lúrio University).

PURPOSE: To describe the strategies used to design and implement three postgraduate programs at Lúrio University (UniLúrio), a resource-limited setting, in northern Mozambique. METHODS: We conducted a longitudinal, descriptive case study from 2011 to 2018 in two phases: 1) needs assessment (2011-2012), 2) implementation strategies (2013-2018), taking into account innovations whenever necessary. RESULTS: Several obstacles and barriers to the establishment of postgraduate programs were identified. These included a lack of a core curricula aimed at postgraduate programs, shortage of human resources for teaching and mentorship, limited teaching and research infrastructures, limited financial resources, and lack of administrative capacity. With the support of the Medical Education Partnership Initiative (MEPI), three Master degree programs were designed and implemented. During the period of 2013-2018, UniLúrio enrolled 202 students, distributed as follows: Master degree in Tropical Medicine and Global Health (55), Master degree in Health Professional Education (99), and Master degree in Nutrition and Food Security (48). Of those, 152 (75.2%) obtained a Postgraduate Diploma as they did not present a master dissertation, 89 (44.0%) obtained their Master degree, 30 (14.8%) dropped out, and 20 (9.9%) are awaiting decision. UniLurio's staff trained a Master's degree or a Postgraduate Diploma in 34 (16.8%) and 15 (7.4%), respectively. Our strategies allowed us to improve research capacity building, and set the basis for long-term sustainability by allowing for the establishment of other postgraduate programs, and offered UniLurio a strong role in its internationalization. CONCLUSION: By sharing multiple resources, long-lasting partnerships were established with multiple institutions, and competency-based training and postgraduate studies management were developed. Research and eLearning were leveraged, retention and faculty development was enhanced, and some inequalities within the country were reduced. These strategies and innovations can be applied to other resource-limited settings, allowing the scaleup of health professional's training and research capacity building.

Cardiovascular Diseases in Sub-Saharan Africa Compared to High-Income Countries: An Epidemiological Perspective.

Non-communicable diseases (NCDs) are the second common cause of death in sub-Saharan Africa (SSA) accounting for about 35% of all deaths, after a composite of communicable, maternal, neonatal, and nutritional diseases. Despite prior perception of low NCDs mortality rates, current evidence suggests that SSA is now at the dawn of the epidemiological transition with contemporary double burden of disease from NCDs and communicable diseases. In SSA, cardiovascular diseases (CVDs) are the most frequent causes of NCDs deaths, responsible for approximately 13% of all deaths and 37% of all NCDs deaths. Although ischemic heart disease (IHD) has been identified as the leading cause of CVDs mortality in SSA followed by stroke and hypertensive heart disease from statistical models, real field data suggest IHD rates are still relatively low. The neglected endemic CVDs of SSA such as endomyocardial fibrosis and rheumatic heart disease as well as congenital heart diseases remain unconquered. While the underlying aetiology of heart failure among adults in high-income countries (HIC) is IHD, in SSA the leading causes are hypertensive heart disease, cardiomyopathy, rheumatic heart disease, and congenital heart diseases. Of concern is the tendency of CVDs to occur at younger ages in SSA populations, approximately two decades earlier compared to HIC. Obstacles hampering primary and secondary prevention of CVDs in SSA include insufficient health care systems and infrastructure, scarcity of cardiac professionals, skewed budget allocation and disproportionate prioritization away from NCDs, high cost of cardiac treatments and interventions coupled with rarity of health insurance systems. This review gives an overview of the descriptive epidemiology of CVDs in SSA, while contrasting with the HIC and highlighting impediments to their management and making recommendations. Highlights: - The burden of non-communicable diseases including cardiovascular diseases is rising in SSA.- Levels of hypertension diagnosis, treatment, and control are low at <40%, <35%, and 10-20%, respectively, and more than 40% of patients with diabetes are not aware of their diagnosis in SSA.- SSA has 23% of the world's prevalent rheumatic heart disease cases.- The leading causes of heart failure in SSA are hypertensive heart disease, cardiomyopathy, and rheumatic heart disease, with ischemic heart disease accounting for <10% of cases compared to >50% in high-income countries.

Challenges and Special Aspects of Pulmonary Hypertension in Middle- to Low-Income Regions: JACC State-of-the-Art Review.

Challenges and special aspects related to the management and prognosis of pulmonary hypertension (PH) in middle- to low-income regions (MLIRs) range from late presentation to comorbidities, lack of resources and expertise, cost, and rare options of lung transplantation. Expert consensus recommendations addressing the specific challenges for prevention and therapy of PH in MLIRs with limited resources have been lacking. To date, 6 MLIR-PH registries containing mostly adult patients with PH exist. Importantly, the global prevalence of PH is much higher in MLIRs compared with high-income regions: group 2 PH (left heart disease), pulmonary arterial hypertension associated with unrepaired congenital heart disease, human immunodeficiency virus, or schistosomiasis are highly prevalent. This consensus statement provides selective, tailored modifications to the current PH guidelines to address the specific challenges faced in MLIRs, resulting in the first pragmatic and cost-effective consensus recommendations for PH care providers, patients, and their families.

Challenges in addressing the knowledge gap on endomyocardial fibrosis through community-based studies.

Endomyocardial fibrosis (EMF) is a poverty-related disease of unknown origin that afflicts predominantly young people of certain rural areas in low-income countries and can be used to expose global disparities in cardiovascular research. Despite affecting predominantly young people and causing high morbidity and mortality, efforts to understand its mechanisms and natural history have been hampered by the incapacity to detect the early stages of the disease in endemic areas. Dietary, environmental and infectious factors seem to combine in susceptible individuals to give rise to an inflammatory process that leads to endomyocardial damage and scar formation. Lack of awareness by health professionals and low access to health care determine late diagnosis, when complications such as chronic heart failure, thromboembolism and arrhythmia are already present. Open-heart surgery to detach the endocardial fibrous tissue and repair the atrioventricular valve, remains the last resource to prolong patients' survival. Community-based research is therefore needed to understand the epidemiology of EMF, detect early disease, uncover its pathogenesis and explore new therapeutic targets. Our research has shown that echocardiographic screening using standard criteria adds sensitivity and precision to the diagnosis, particularly in asymptomatic disease, providing an opportunity for longitudinal community-based research. However, researchers face major constraints in rural settings where EMF is endemic, including socioeconomic, cultural, geographical and administrative barriers. In presenting our experience we aim to describe the challenges and discuss the lessons learned while implementing community-based research in a highly endemic area in southern Mozambique, one of the poorest countries in the world. Additionally, we discuss how recent advances in medicine-such as use of point-of-care diagnostics, heart failure biomarkers and new imaging techniques-may open new possibilities for high quality research through collaborative partnerships and regional initiatives.

Systems analysis and improvement approach to optimize the hypertension diagnosis and care cascade for PLHIV individuals (SAIA-HTN): a hybrid type III cluster randomized trial.

BACKGROUND: Across sub-Saharan Africa, evidence-based clinical guidelines to screen and manage hypertension exist; however, country level application is low due to lack of service readiness, uneven health worker motivation, weak accountability of health worker performance, and poor integration of hypertension screening and management with chronic care services. The systems analysis and improvement approach (SAIA) is an evidence-based implementation strategy that combines systems engineering tools into a five-step, facility-level package to improve understanding of gaps (cascade analysis), guide identification and prioritization of low-cost workflow modifications (process mapping), and iteratively test and redesign these modifications (continuous quality improvement). As hypertension screening and management are integrated into chronic care services in sub-Saharan Africa, an opportunity exists to test whether SAIA interventions shown to be effective in improving efficiency and coverage of HIV services can be effective when applied to the non-communicable disease services that leverage the same platform. We hypothesize that SAIA-hypertension (SAIA-HTN) will be effective as an adaptable, scalable model for broad implementation. METHODS: We will deploy a hybrid type III cluster randomized trial to evaluate the impact of SAIA-HTN on hypertension management in eight intervention and eight control facilities in central Mozambique. Effectiveness outcomes include hypertension cascade flow measures (screening, diagnosis, management, control), as well as hypertension and HIV clinical outcomes among people living with HIV. Cost-effectiveness will be estimated as the incremental costs per additional patient passing through the hypertension cascade steps and the cost per additional disability-adjusted life year averted, from the payer perspective (Ministry of Health). SAIA-HTN implementation fidelity will be measured, and the Consolidated Framework for Implementation Research will guide qualitative evaluation of the implementation process in high- and low-performing facilities to identify determinants of intervention success and failure, and define core and adaptable components of the SAIA-HTN intervention. The Organizational Readiness for Implementing Change scale will measure facility-level readiness for adopting SAIA-HTN. DISCUSSION: SAIA packages user-friendly systems engineering tools to guide decision-making by front-line health workers to identify low-cost, contextually appropriate chronic care improvement strategies. By integrating SAIA into routine hypertension screening and management structures, this pragmatic trial is designed to test a model for national scale-up.

Assessment of care provision for hypertension at the emergency Department of an Urban Hospital in Mozambique.

BACKGROUND: Management of hypertension in Mozambique is poor, and rates of control are amongst the lowest in the world. Health system related factors contribute at least partially to this situation, particularly in settings where there is scarcity of resources to address the double burden of infectious and non-communicable diseases. This study aimed to assess the management of hypertension in an emergency department (ED). METHODS: During a pragmatic and prospective 30-day snapshot study (with 24 h surveillance) and random profiling of one-in-five presentations to the ED of Hospital Geral de Mavalane, Maputo, we assessed patient's flow and care, as well as health facility's infrastructure and resources through direct observation. Reports from pharmacy and laboratory stocks were used to assess availability of diagnostics and medicines needed for hypertension management. RESULTS: The 1911 hypertensive patients included in the study had several stops during their journey inside the health facility and followed a non-standardized care flow. No clinical protocols or algorithms for risk stratification of hypertension were available. Stock-outs of basic diagnostic tools for risk stratification and medicines were registered. The availability of medicines was 28% on average. CONCLUSIONS: Critical gaps in health facility readiness to address arterial hypertension seen in ED were uncovered, including lack of clinical protocols, insufficient availability of diagnostics and essential medicines, as well as low affordability of the families to guaranty continuum of care. Innovative financing mechanisms are needed to support the health system to address hypertension.

Hypertension in a resource-limited setting: Poor Outcomes on Short-term Follow-up in an Urban Hospital in Maputo, Mozambique.

Mozambique has low levels of detection, treatment, and control of hypertension. However, data on target organ damage and clinical outcomes are lacking. The authors aimed at characterizing the clinical profile, pattern of target organ damage, and short-term outcomes of patients referred to a first referral urban hospital in a low-income setting in Africa. We conducted a prospective descriptive cohort study from February 2016 to May 2017 in Maputo, Mozambique. Adult patients with systolic and diastolic blood pressure ≥180 mm Hg and/or ≥110 mm Hg, respectively, or any systolic blood pressure above 140 mm Hg and/or diastolic blood pressure above 90 mm Hg in the presence of target organ damage (with or without antihypertensive treatment) were submitted to detailed physical examination, funduscopy, laboratory profile, electrocardiography, and echocardiography. Six months after the occurrence of complications (stroke, heart failure, and renal failure), hospital admission and death were assessed. Overall, 116 hypertensive patients were recruited (mean age 57.5 ± 12.8 years old; 111[95.7%] black; 81[70%] female) of which 79 had severe hypertension. The baseline mean values recorded for systolic and diastolic blood pressure were 192.3 ± 23.6 and 104.2 ± 15.2 mm Hg, respectively. Most patients (93; 80.2%) were on antihypertensive treatment. Patients' risk profile revealed dyslipidemia, obesity, and diabetes in 59(54.1%), 48(42.5%), and 23(19.8%), respectively. Target organ damage was found in 111 patients. The commonest being left atrial enlargement 91(84.5%), left ventricular hypertrophy 57(50.4%), hypertensive retinopathy 30(26.3%), and chronic kidney disease 27(23.3%). Major events during 6-month follow-up were hospitalizations in 10.3% and death in 8.6% of the patients. Worsening of target organ damage occurred in 10 patients: four stroke, two heart failure, and four renal damage. Patients with severe hypertension and target organ damage were young with high-risk profile, low hypertension control, and high occurrence of complications during short-term follow-up. Efforts to improve high blood pressure control are needed to reduce premature mortality in this highly endemic poor setting.

Endomyocardial Fibrosis: an Update After 70 Years.

PURPOSE OF REVIEW: This review aims at highlighting the need to better understand the pathogenesis and natural history of endomyocardial fibrosis when set against its changing endemicity and disease burden, improvements in diagnosis, and new options for clinical management. RECENT FINDINGS: Progress in imaging diagnostic techniques and availability of new targets for drug and surgical treatment of heart failure are contributing to earlier diagnosis and may lead to improvement in patient survival. Endomyocardial fibrosis was first described in Uganda by Davies more than 70 years ago (1948). Despite its poor prognosis, the etiology of this neglected tropical restrictive cardiomyopathy still remains enigmatic nowadays. Our review reflects on the journey of scientific discovery and construction of the current guiding concepts on this mysterious and fascinating condition, bringing to light the contemporary knowledge acquired over these years. Here we describe novel tools for diagnosis, give an overview of the improvement in clinical management, and finally, suggest research themes that can help improve patient outcomes focusing (whenever possible) on novel players coming into action.

Closing the Gaps on Medical Education in Low-Income Countries Through Information & Communication Technologies: The Mozambique Experience.

Background: Medical training in developing countries has continuously faced challenges to produce the needed number of cadres and maintain the needed quality standards. Mozambique, a low-income country in Southern Africa, has a major disparity in distribution of medical doctors in the country and only a small proportion are trained as specialists and/or retained as faculty. In this context, we thought that Information and Communication Technologies (ICT) are an attractive tool to support expansion of medical training and residency programs and designed a strategy for its use to promote changes in the learning environment of a university teaching hospital in this country. Approach: Beginning in 2010-under the Medical Education Partnership Initiative between Universidad Eduardo Mondlane, Mozambique, and University of California San Diego, United States of America - we conducted extensive interviews to 21 UEM faculty and medical trainees to assess barriers to education and medical care at the major referral hospital in Mozambique. Then, changes were made to address the issues raised mainly through building an ICT infrastructure to improve connectivity, improving access to medical information, distributing communication and mobile medical devices, as well as fostering exchange between students, residents and faculty members. These changes were tracked years after to evaluate adoption. Main Findings & Discussion: Internet access with large bandwidth and devices such as tablets and computers were distributed to increase access to medical information. The students: resident ratio improved from 13:1 to 5:1 at the end of the project. Additional 25 new faculty members were involved in clinical training, mainly through incentives such as faculty development courses and research training. Teleconferences and other exchanges using ICT have evolved from being used as a platform for weekly clinical rounds and case discussions, to become a day-to-day tool for implementation of quality improvement processes and research projects. New exchange programs between local and foreign institutions were fostered to create a growing network with over 20 institutions at the end of the program. Importantly, these changes persisted beyond the project, and constituted a driver for transformative education and distance learning. Conclusion: Context-tailored use of ICT and mobile medical devices transformed medical education by improving the learning environment, addressing scarcity and low quality of trained doctors in a low-income setting of Africa. This strategy has the potential to reduce health disparities and contribute to achieving universal health coverage. Efforts to guaranty sustainability and health professional's retention are warranted.

Acquired heart disease in low-income and middle-income countries.

The burden of illness associated with acquired cardiac disease in children in low-income and middle-income countries (LMIC) is significant and may be equivalent to that of congenital heart disease. Rheumatic heart disease, endomyocardial fibrosis, cardiomyopathy (including HIV cardiomyopathy) and tuberculosis are the most important causes. All are associated with poverty with the neediest children having the least access to care. The associated mortality and morbidity is high. There is an urgent need to improve cardiac care in LMIC, particularly in sub-Saharan Africa and parts of Southeast Asia where the burden is highest.
