Clinical Characteristics,Complications, and Treatment Practices in Patients With RHD: 6-Year Results From HP-RHD Registry

Background

Despite the high prevalence of rheumatic heart disease (RHD) in developing countries such as India, data on characteristics, complications, and treatment practices are lacking. The HP-RHD (Himachal Pradesh Rheumatic Heart Disease) registry aimed at reporting these parameters in patients with RHD from a northern state of India.

Population Prevalence and Correlates of Prolonged QT Interval: Cross-Sectional,Population-Based Study From Rural Uganda

Objectives

We aimed to estimate the prevalence and correlates of QT interval prolongation in rural Uganda.

Global Unmet Needs in Cardiac Surgery

More than 6 billion people live outside industrialized countries and have insufficient access to cardiac surgery. Given the recently confirmed high prevailing mortality for rheumatic heart disease in many of these countries together with increasing numbers of patients needing interventions for lifestyle diseases due to an accelerating epidemiological transition, a significant need for cardiac surgery could be assumed. Yet, need estimates were largely based on extrapolated screening studies while true service levels remained unknown. A multi-author effort representing 16 high-, middle-, and low-income countries was undertaken to narrow the need assessment for cardiac surgery including rheumatic and lifestyle cardiac diseases as well as congenital heart disease on the basis of existing data deduction. Actual levels of cardiac surgery were determined in each of these countries on the basis of questionnaires, national databases, or annual reports of national societies. Need estimates range from 200 operations per million in low-income countries that are nonendemic for rheumatic heart disease to >1,000 operations per million in high-income countries representing the end of the epidemiological transition. Actually provided levels of cardiac surgery range from 0.5 per million in the assessed low- and lower-middle income countries (average 107 ± 113 per million; representing a population of 1.6 billion) to 500 in the upper-middle-income countries (average 270 ± 163 per million representing a population of 1.9 billion). By combining need estimates with the assessment of de facto provided levels of cardiac surgery, it emerged that a significant degree of underdelivery of often lifesaving open heart surgery does not only prevail in low-income countries but is also disturbingly high in middle-income countries.     

Relationship of Smoking to Hypertension in a Developing Country

Background

Smoking and hypertension are 2 leading causes of death worldwide, and it has been claimed that smoking is a cause of hypertension despite inconsistent results in the literature. In addition, the literature focuses mostly on developed countries, although more people in developing countries are adversely affected by smoking and hypertension.

People's perception of malaria in Mbarara,Uganda

To understand people's perceptions of malaria and their implications for control programmes, we held focus group discussions (FGDs) and conducted semi-structured interviews (SSIs) with community members in Mbarara, Uganda. Mosquitoes were perceived as the cause or transmitters of malaria but the causation/transmission model of people differed from biomedical facts. Convulsions, a common complication of malaria, were perceived as a supernatural ailment, best treated by traditional medicine, as was splenomegaly. More than 70% of the patients with malaria had treatment from non-public health sources. This included self-treatment (13%), use of traditional healers (12%) and use of private medical practitioners/pharmacists (69%). Although 26% (887/3309) used bednets to prevent malaria, only 7% of the nets were impregnated with insecticide. People who did not use bednets cited discomfort because of heat/humidity and their high cost as reasons. To improve malaria control in this area, people need to be educated on the connection between mosquitoes and malaria and on seeking biomedical treatment for convulsions. The malaria control programme could collaborate with traditional and private health care providers to increase promotion of insecticide-impregnated mosquito nets.     

A Human-Centered Approach to CV Care: Infrastructure Development in Uganda

In this case study, we describe an ongoing approach to develop sustainable acute and chronic cardiovascular care infrastructure in Uganda that involves patient and provider participation. Leveraging strong infrastructure for HIV/AIDS care delivery, University Hospitals Harrington Heart and Vascular Institute and Case Western Reserve University have partnered with U.S. and Ugandan collaborators to improve cardiovascular capabilities. The collaboration has solicited innovative solutions from patients and providers focusing on education and advanced training, penicillin supply, diagnostic strategy (e.g., hand-held ultrasound), maternal health, and community awareness. Key outcomes of this approach have been the completion of formal training of the first interventional cardiologists and heart failure specialists in the country, establishment of 4 integrated regional centers of excellence in rheumatic heart disease care with a national rheumatic heart disease registry, a penicillin distribution and adherence support program focused on retention in care, access to imaging technology, and in-country capabilities to treat advanced rheumatic heart valve disease.     

Clinical correlates of suicidality among individuals with HIV infection and AIDS disease in Mbarara,Uganda

The association between suicidality and HIV/AIDS has been demonstrated for three decades, but little is know about risk factors that can help understand this association and help identify who is most at risk. Few research studies have been conducted in sub-Saharan Africa, a region that accounts for more than 70% of the HIV global burden. This paper describes clinical risk factors for suicidality among individuals with HIV infection and AIDS disease in Mbarara, Uganda. In this study, suicidality includes both suicidal ideation and suicidal attempts. A cross-sectional survey was conducted with 543 HIV-positive individuals aged 15 years and above, recruited from 2 HIV specialised clinics in Mbarara. Using logistic regression analysis, factors significantly associated with suicidality at 95% confidence interval were identified. The rate of suicidality was 10% (n = 54; 95% CI: 5.00–15.00). Risk factors for suicidality were: perception of poor physical health (OR 2.22, 95% CI 1.23–3.99, p = 0.007), physical pain (OR 1.83, 95% CI 1.01–3.30, p = 0.049), reducing work due to illness (OR = 2.22, 95% CI 1.23–3.99, p = 0.004) and recent HIV diagnosis (OR 1.02, 95% CI 1.01–1.03, p = 0.001). These findings suggest that HIV/AIDS in south-western Uganda is associated with a considerable burden of suicidality. HIV is associated with several clinical factors that increase vulnerability to suicidality. There is need for more appropriate interventions targeting these clinical risk factors, systematic suicide risk assessment and management of suicidal ideation and behaviours in HIV care.     

Capacity and Readiness for Implementing Evidence-Based Task-Strengthening Strategies for Hypertension Control in Ghana: A Cross-Sectional Study

BackgroundAssessing the practice capacity for hypertension management and control within community-based health planning and services system is an important step toward implementing evidence-based interventions to reduce uncontrolled hypertension at the community level.ObjectivesTo assess the capacity and readiness of community health workers to implement a task-strengthening strategy for hypertension control (TASSH) at the community level.MethodsThis was a cross-sectional study guided by the Consolidated Framework for Implementation Research conducted among community health workers in 6 contiguous districts within the Brong-Ahafo Region of Ghana. Study variables were described using frequency tables.ResultsA total of 179 community health officers (CHOs) were interviewed. The majority of respondents knew lifestyle-related messages to be provided to their clients such as heart-healthy diets (91.6%, n = 164), physical activity (90.5%, n = 162), and low sodium intake (88.3%, n = 158), but not about other lifestyle-modifying messages such as caffeine reduction (46.4%, n = 83). The majority (79%) of the respondents did not know the names of the first-line hypertension medications. Fifty-one percent of respondents did not know about the blood pressure threshold for initiation of blood pressure management. About 90% of respondents had not been trained on hypertension management. More than 80% are however motivated to implement the TASSH intervention.ConclusionsThe majority of CHOs in this study were aware of lifestyle modifications such as diet modifications and increase in physical activity. However, their knowledge was limited in the blood pressure threshold for initiating treatment and in the knowledge of first-line hypertension medication, irrespective of the number of years practiced. Training on hypertension is also low. However, CHOs are motivated to control hypertension at the community level. Community-level interventions such as TASSH can leverage on their motivation to demonstrate an impact on hypertension control.     

Development,Testing, and Implementation of a Training Curriculum for Nonphysician Health Workers to Reduce Cardiovascular Disease

Background

Cardiovascular disease (CVD) is the leading cause of death worldwide. The need to address CVD is greatest in low- and middle-income countries where there is a shortage of trained health workers in CVD detection, prevention, and control.

Processes and Outcomes of HIV Serostatus Disclosure to Sexual Partners among People Living with HIV in Uganda

Disclosure of HIV serostatus to sexual partners supports risk reduction and facilitates access to prevention and care services for people living with HIV/AIDS. To assess health and social predictors of disclosure as well as to explore and describe the process, experiences and outcomes related to disclosure of HIV-infected men and women in Eastern Uganda, we conducted a study among HIV-infected men and women who were clients of The AIDS Support Organization (TASO) in Jinja, Uganda. We enrolled TASO clients in a cross-sectional study on transmission risk behavior. Demographic and behavioral data and CD4 cell count measurements were collected. Among 1,092 participants, 42% were currently sexually active and 69% had disclosed their HIV serostatus to their most recent sexual partner. Multivariate logistic regression analysis showed that disclosure of HIV-status was associated with being married, having attended TASO for more than 2 years, increased condom use, and knowledge of partner’s serostatus. From these clients, 45 men and women were purposefully selected and interviewed in-depth on disclosure issues. Positive outcomes included risk reduction behavior, partner testing, increased care-seeking behavior, anxiety relief, increased sexual communication, and motivation to plan for the future. The findings and conclusions in this report are those of the author and do not necessarily represent the views of the Centers for Disease Control and Prevention.     

Association Between Perceived Neighborhood Characteristics and Carotid Artery Intima-Media Thickness: Cross-Sectional Results From the ELSA-Brasil Study

BackgroundLiving in a neighborhood with a low socioeconomic context may increase the risk of coronary heart disease. However, few studies have explored the impact of neighborhood characteristics on subclinical atherosclerosis, and their role as a risk factor for cardiovascular disease has not yet been studied in poor countries.ObjectivesThis study aimed to investigate the association between perceived neighborhood characteristics and subclinical atherosclerosis in a large sample of adults, using cross-sectional data from the ELSA-Brasil (Brazilian Longitudinal Study of Adult Health).MethodsParticipants free of clinical coronary artery disease answered a questionnaire designed to assess their perceptions regarding 6 neighborhood dimensions: social cohesion, walkability, availability of healthy food, safety, witnessed violence, and personal victimization. The scores of each domain were used as independent variables. Common carotid intima-media thickness (CCIMT) was used as a dependent variable. Then linear regression models, adjusted by demographic, socioeconomic, and cardiovascular factors, were used.ResultsA total of 9,923 adults (mean age = 51.5 ± 8.9 years, 44% male, 55% white) were examined. In the univariate analysis, better walkability (β = ?0.62, 95% confidence interval [CI]: ?1.01 to ?0.23; p = 0.002) and low witnessed violence (β = ?1.95; 95% CI: ?2.96 to -0.94; p < 0.0001) were associated with lower CCIMT, whereas low personal victimization was associated with higher CCIMT (β = 10.70; 95% CI: 4.55 to 16.85; p = 0.001). A borderline interaction between neighborhood domain and sex was found. Better social cohesion may be associated with larger CCIMT among women, whereas better safety was associated with lower CCIMT among men. Multiple imputation for missing CCIMT data showed similar results.ConclusionsThe perception of living in a more walkable environment and in a neighborhood where people witness fewer violent episodes can provide protection on the early phases of the atherosclerosis process. Less stress and the practice of physical activity may explain the protection.     

Alcohol Use and Food Insecurity Among People Living with HIV in Mbarara,Uganda and St. Petersburg,Russia

Food insecurity (FI) is a documented problem associated with adverse health outcomes among HIV-infected populations. Little is known about the relationship between alcohol use and FI. We assessed whether heavy alcohol use was associated with FI among HIV-infected, antiretroviral therapy (ART)-naïve cohorts in Uganda and Russia. Inverse probability of treatment weighted logistic regression models were used to evaluate the association using cross-sectional baseline data. FI was experienced by half of the Russia cohort (52 %) and by a large majority of the Uganda cohort (84 %). We did not detect an association between heavy alcohol use and FI in either cohort (Russia: AOR = 0.80, 95 % CI 0.46, 1.40; Uganda: AOR = 1.00, 95 % CI 0.57, 1.74) or based on the overall combined estimate (AOR = 0.89, 95 % CI 0.60, 1.33). Future studies should explore the determinants of FI in HIV-infected populations to inform strategies for its mitigation.     

Initial Rhythm and Resuscitation Outcomes for Patients Developing Cardiac Arrest in Hospital: Data From Low-Middle Income Country

Stakeholder Engagement in Planning the Design of a National Needs Assessment for Cardiovascular Disease Prevention and Management in Nepal

BackgroundThere is growing support for stakeholder engagement in health research, but the actual impact of such engagement has not been well established.ObjectivesThis paper describes the stakeholder engagement process and evaluation during the planning of the national needs assessment for cardiovascular disease in Nepal.MethodsWe used personal and professional networks to identify relevant stakeholders within the 7Ps framework (Patients and the Public, Providers, Purchasers, Payers, Public Policy Makers and Policy Advocates, Product Makers and the Principal Investigators) to develop a plan for assessing cardiovascular health needs in Nepal. We consulted 40 stakeholders through 2 meetings in small groups and a workshop in a large group to develop the study methods, conceptual framework, and stakeholder engagement process. We interviewed 33 stakeholders to receive feedback on the stakeholder engagement process.ResultsWe engaged 80% of the targeted stakeholders through small group discussions and a workshop. Three of 5 recommendations from the small group discussion were aimed at improving the stakeholder engagement process and 2 were aimed to improve the research methods. Eleven of 27 recommendations from the workshop aimed to improve the research methods, 4 aimed to improve stakeholder engagement, and 2 helped to expand the scope of dissemination. Ten were irrelevant or could not be incorporated due to resource limitation. Most stakeholders noted that the workshop provided an open platform for a multisectoral group to colearn from one another and share ideas. Others highlighted that the discussion generated insights to enhance research by incorporating expertise and ideas from different perspectives. The major challenges discussed were about committing the time for engagement.ConclusionsThe stakeholder engagement process positively affected the design of our research. This study provides important insights for future researchers that aim to engage stakeholders in national-level assessment programs in the health care system in the context of Nepal.     

Cardiac arrhythmia and hip fracture
