    BackgroundDiagnosis and treatment for Rheumatic Heart Disease (RHD) is inaccessible for many of the 33 million people in low and middle income countries living with this disease. More knowledge about risk factors and pathophysiologic mechanisms involved is needed in order to prevent disease and optimize treatment. This study investigated risk factors in a Nepalese population, with a special focus on Vitamin D deficiency because of its immunomodulatory effects.MethodsNinety-nine patients with confirmed RHD diagnosis and 97 matched, cardiac-healthy controls selected by echocardiography were recruited from hospitals in the Central and Western region of Nepal. Serum 25(OH)D concentrations were assessed using dried blood spots and anthropometric values measured to evaluate nutritional status. Conditional logistic regression analysis was used to define association between vitamin D deficiency and RHD.ResultsThe mean age of RHD patients was 31 years (range 9-70) and for healthy controls 32 years (range 9-65), with a 4:1 female to male ratio. Vitamin D levels were lower than expected in both RDH and controls. RHD patients had lower vitamin D levels than controls with a mean s-25(OH)D concentration of 39 nmol/l (range 8.7-89.4) compared with controls 45 nmol/l (range 14.5-86.7) (p-value = 0.02). People with Vitamin D insufficiency had a higher risk (OR = 2.59; 95% CI: 1.04-6.50) of also having RHD compared to people with Vitamin D concentrations >50 nmol/l. Body mass index was significantly lower in RHD patients (22.6; 95% CI, 21.5-23.2) compared to controls (24.2; 95% CI, 23.3-25.1).ConclusionRHD patients in Nepal have lower Vitamin D levels and overall poor nutritional status compared to the non-RHD controls. Longitudinal studies are needed to explore the causality between RHD and vitamin D level. Future research is also recommended among Nepali general population to confirm the low level of vitamin D as reported in our control group

    AbstractObjectives: Our institutional experience with 73 pediatric patients undergoing cardiac transplantation between January 1, 1990, and December 31, 1999, was reviewed to determine the impact of unconventional donor and recipient management protocols implemented to extend the availability of this therapy. Methods and results: The introduction of donor blood cardioplegic solution with added insulin was associated with a significant improvement in patient and graft survival (hazard ratio [Cox] = 0.25, P =.08), despite significantly longer ischemic times with this protocol compared with the use of crystalloid-based donor procurement techniques (P <.01). Eleven patients underwent intentional transplantation of ABO-incompatible donor hearts with the aid of a protocol of plasma exchange on bypass. In this subgroup, there were 2 early deaths caused by nonspecific graft failure (n = 1) and respiratory complications with mild vascular rejection (n = 1), and there was 1 late death caused by lymphoma. ABO-incompatible transplantation was not a risk factor for death by multivariate analysis. The postoperative course in these patients suggests minimal reactivity directed against incompatible grafts on the basis of low anti-donor blood group antibody production, in association with a favorable rejection profile. Ten of 13 patients requiring preoperative support with an extracorporeal membrane oxygenator survived transplantation; there were 3 additional late deaths in this subgroup (hazard ratio = 2.88, P =.05). Conclusions: The results with pediatric cardiac transplantation continue to improve as a result of changes in both surgical and medical protocols permitting successful treatment of patients conventionally considered at high risk or unsuitable for transplantation.

    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 US4.70–US4.70–US13.70 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.publishedVersio

    Know thy neighbors: The status of cardiac surgery in the South Asian countries around India

    No full text
    Objectives: The South Asian neighboring countries of India include Bangladesh, Bhutan, Nepal, The Maldives, Pakistan and Sri Lanka. Interestingly all these countries possess either a land or a sea border with India and no border among themselves. These countries have historic, cultural, ethnic and genetic links with India. The paper describes the developmental history and current status of cardiac surgery in these countries. Methods: Thorough search of the printed and electronic materials has been made. The authors visited all these countries and contacted the eminent surgeons personally or through mails. All the information is cross-checked and compiled. Record keeping is not well organized in most of these countries. Best information often came from unusual sources like Anesthetists’ society or the corporate houses. Results: Four of these countries Bangladesh, Nepal, Pakistan and Sri Lanka have their cardiac surgical programs. Collectively they perform around 38000 cardiac operations a year which is a quarter of the cases performed in India. These countries are important sources of medical tourism in India which is worth 3 billion US$ of business annually. Conclusion: When the number of operations per million populations is considered, Bangladesh and Nepal are lagging behind India where as Pakistan has a comparable figure. Sri Lanka with 265 cardiac operations/million populations has the best figures in the region. However when compared with the Western countries even the Lankan figures also look quite inadequate

    IntroductionMany countries with weaker health systems are struggling to put together a coherent strategy against the COVID-19 epidemic. We explored COVID-19 control strategies that could offer the greatest benefit in resource limited settings.MethodsUsing an age-structured SEIR model, we explored the effects of COVID-19 control interventions-a lockdown, physical distancing measures, and active case finding (testing and isolation, contact tracing and quarantine)-implemented individually and in combination to control a hypothetical COVID-19 epidemic in Kathmandu (population 2.6 million), Nepal.ResultsA month-long lockdown will delay peak demand for hospital beds by 36 days, as compared to a base scenario of no intervention (peak demand at 108 days (IQR 97-119); a 2 month long lockdown will delay it by 74 days, without any difference in annual mortality, or healthcare demand volume. Year-long physical distancing measures will reduce peak demand to 36% (IQR 23%-46%) and annual morality to 67% (IQR 48%-77%) of base scenario. Following a month long lockdown with ongoing physical distancing measures and an active case finding intervention that detects 5% of the daily infection burden could reduce projected morality and peak demand by more than 99%.ConclusionLimited resource settings are best served by a combination of early and aggressive case finding with ongoing physical distancing measures to control the COVID-19 epidemic. A lockdown may be helpful until combination interventions can be put in place but is unlikely to reduce annual mortality or healthcare demand

    High salt (sodium chloride) intake raises blood pressure and increases the risk of developing hypertension, a major risk factor for cardiovascular disease. Little is known about salt intake in Nepal, and no study has estimated salt consumption from 24‐hour urinary sodium excretion. Participants (n = 451) were recruited from the Community‐Based Management of Non‐Communicable Diseases in Nepal (COBIN) cohort in 2018. Salt intake was estimated by analyzing 24‐hour urinary sodium excretion. Multivariate linear regression was used to estimate differences in salt intake. The mean (±SD) age and salt intake were 49.6 (±9.8) years and 13.3 (±4.7) g/person/d, respectively. Higher salt intake was significantly associated with male gender (ÎČ for female = −2.4; 95% CI: −3.3, −1.4) and younger age (ÎČ (10 years) = −1.4; 95% CI: −1.4, −0.5) and higher BMI (ÎČ = 0.1; 95% CI: 0.0, 0.2). A significant association was also found between increase in systolic blood pressure and higher salt intake (ÎČ = 0.3; 95% CI: 0.0, 0.7). While 55% reported that they consumed just the right amount of salt, 98% were consuming more than the WHO recommended salt amount (<5 g/person/d). Daily salt intake in this population was over twice the limit recommended by the WHO, suggesting a substantial need to reduce salt intake in this population. It also supports the need of global initiatives such as WHO's Global Hearts Initiative SHAKE technical package and Resolves to Save Lives for sodium reduction in low‐ and middle‐income countries like Nepal
