An assessment of progress towards universal health coverage in Brazil, Russia, India, China, and South Africa (BRICS).

Brazil, Russia, India, China, and South Africa (BRICS) represent almost half the world's population, and all five national governments recently committed to work nationally, regionally, and globally to ensure that universal health coverage (UHC) is achieved. This analysis reviews national efforts to achieve UHC. With a broad range of health indicators, life expectancy (ranging from 53 years to 73 years), and mortality rate in children younger than 5 years (ranging from 10·3 to 44·6 deaths per 1000 livebirths), a review of progress in each of the BRICS countries shows that each has some way to go before achieving UHC. The BRICS countries show substantial, and often similar, challenges in moving towards UHC. On the basis of a review of each country, the most pressing problems are: raising insufficient public spending; stewarding mixed private and public health systems; ensuring equity; meeting the demands for more human resources; managing changing demographics and disease burdens; and addressing the social determinants of health. Increases in public funding can be used to show how BRICS health ministries could accelerate progress to achieve UHC. Although all the BRICS countries have devoted increased resources to health, the biggest increase has been in China, which was probably facilitated by China's rapid economic growth. However, the BRICS country with the second highest economic growth, India, has had the least improvement in public funding for health. Future research to understand such different levels of prioritisation of the health sector in these countries could be useful. Similarly, the role of strategic purchasing in working with powerful private sectors, the effect of federal structures, and the implications of investment in primary health care as a foundation for UHC could be explored. These issues could serve as the basis on which BRICS countries focus their efforts to share ideas and strategies.

Congenital Hyperlipidemia in Infants for Congenital Cardiac Surgery.

Infants with concurrent severe hypertriglyceridemia and complex congenital heart disease are a rare occurrence and can have life-threatening consequences when undergoing surgical intervention. This case series outlines two instances involving infants undergoing total anomalous pulmonary venous connection repair and surgical closure of a ventricular septal defect. The study explores troubleshooting the effects of hypertriglyceridemia on perioperative outcomes.

Local steroid therapy as the first-line treatment for boys with symptomatic phimosis - a long-term prospective study.

AIM: Phimosis is a common paediatric urological disorder and often necessitates circumcision. We prospectively evaluated local steroid therapy (LST) as the first choice therapy for such children. METHODS: Two hundred and sixty symptomatic boys up to 15 years of age (mean 34 months) with phimosis were started on betamethasone dipropionate (0.05%) application on gently stretched prepuce twice a day. Follow-up visits were arranged at the end of weeks 1, 2 and 4 and 6 months. Grade of phimosis was objectively graded. RESULTS: Ninety one percent of the boys showed a successful outcome at the end of 4 weeks; 72% responded in first week, further 16% responded in week 2, and only 2.6% achieved alleviation of phimosis on further application of LST beyond 2 weeks. Fourty two (17.8%) boys had a recurrence of phimosis on a long-term follow-up (mean - 25.4 months, range 6-48 months); thus, the long-term success rate was 77%, while 60 (23%) boys underwent surgery. CONCLUSION: Local steroid therapy is safe and successful in alleviating symptomatic tight foreskin in a large majority of children. The response can be seen as early as 1 week; most of the children respond by week 2 and continuing therapy further may not be very effective.

Assessment of physical activity using accelerometry, an activity diary, the heart rate method and the Indian migration study questionnaire in south Indian adults.

OBJECTIVE: To validate questionnaire-based physical activity level (PAL) against accelerometry and a 24 h physical activity diary (24 h AD) as reference methods (Protocol 2), after validating these reference methods against the heart rate-oxygen consumption (HRVO2) method (Protocol 1). DESIGN: Cross-sectional study. SETTING: Two villages in Andhra Pradesh state and Bangalore city, South India. SUBJECTS: Ninety-four participants (fifty males, forty-four females) for Protocol 2; thirteen males for Protocol 1. RESULTS: In Protocol 2, mean PAL derived from the questionnaire (1.72 (sd 0.20)) was comparable to that from the 24 h AD (1.78 (sd 0.20)) but significantly higher than the mean PAL derived from accelerometry (1.36 (sd 0.20); P < 0.001). Mean bias of PAL from the questionnaire was larger against the accelerometer (0.36) than against the 24 h AD (-0.06), but with large limits of agreement against both. Correlations of PAL from the questionnaire with that of the accelerometer (r = 0.28; P = 0.01) and the 24 h AD (r = 0.30; P = 0.006) were modest. In Protocol 1, mean PAL from the 24 h AD (1.65 (sd 0.18)) was comparable, while that from the accelerometer (1.51 (sd 0.23)) was significantly lower (P < 0.001), than mean PAL obtained from the HRVO2 method (1.69 (sd 0.21)). CONCLUSIONS: The questionnaire showed acceptable validity with the reference methods in a group with a wide range of physical activity levels. The accelerometer underestimated PAL in comparison with the HRVO2 method.

Rationale and design of the Rural Andhra Pradesh Cardiovascular Prevention Study (RAPCAPS): a factorial, cluster-randomized trial of 2 practical cardiovascular disease prevention strategies developed for rural Andhra Pradesh, India.

BACKGROUND: Developing countries are experiencing increasing levels of cardiovascular disease (CVD). Although there is a good understanding of how to deliver CVD prevention programs in developed countries, there are few data regarding strategies for CVD prevention in resource-poor settings. This study aimed to implement and evaluate a CVD prevention program in a rural area of India. METHODS: The 2 strategies of CVD prevention to be investigated are an algorithm-based care approach and a health-promotion campaign. A factorial, cluster-randomized trial design will be used to evaluate these, in which villages will be exposed to one, both, or neither of the interventions for a period of about 12 months. Surveys of households in every village will be used to assess outcomes in all high-risk individuals and a sample of the general adult population. RESULTS: The primary outcome of the algorithm-based component of this study will be the percentage of high-risk individuals that have been "identified"-defined as having received a cardiovascular-risk assessment in the last 12 months. The primary outcome for the health-promotion component will be the percentage of the adult population with correct knowledge about the effects of 6 behavioral determinants of cardiovascular risk (green-leafy vegetables, fruits, oily foods, salt, smoking, physical activity). Secondary outcomes include a range of measures defining uptake of different preventive strategies. CONCLUSIONS: This study will provide evidence about the effectiveness of a simple practical mechanism of CVD preventive care specifically designed for delivery in a resource-poor area in India.

Verbal autopsy coding: are multiple coders better than one?

OBJECTIVE: To assess the impact on the reported cause-of-death patterns of a verbal autopsy coding strategy based on a review of every death by multiple coders versus a single coder. METHODS: Deaths in 45 villages (total population 180,162) in southern India were documented during 12 months in 2003-2004, and a standard verbal autopsy questionnaire was completed for each death. Two physician coders, each unaware of the other's decisions, assigned an underlying cause of death in accordance with the causes listed in the chapter headings of the International classification of diseases and related health problems, 10th revision (ICD-10). For the three chapter headings that applied to more than 100 of the deaths, agreement for subsets of causes of death within the chapter was also analysed. In the event of discrepancies, a third coder was used to finalize a cause of death. Cohen's kappa statistic (Kappa) was used to measure levels of agreement between the two physician coders. FINDINGS: In total, 1354 deaths were documented, and a verbal autopsy was completed for 1329 (98%) of them. At the chapter heading level of the ICD-10, physician coders assigned the same cause to 1255 deaths (94%) (Kappa = 0.93; 95% confidence interval: 0.92-0.94). The patterns of death derived from the causes assigned by each physician were all very similar to the patterns obtained through the consensus process, with the rank order of the 10 leading causes of death being the same for all three coding methods. CONCLUSION: Duplicate coding of verbal autopsy results has little advantage over a single-coder system for mortality surveillance or for identifying population patterns of death. Resources could be better diverted to other parts of the mortality surveillance process, such as validation.

Prevention of chronic diseases: a call to action.

Chronic (non-communicable) diseases--principally cardiovascular diseases, cancer, chronic respiratory diseases, and diabetes--are leading causes of death and disability but are surprisingly neglected elements of the global-health agenda. They are underappreciated as development issues and underestimated as diseases with profound economic effects. Achievement of the global goal for prevention and control of chronic diseases would avert 36 million deaths by 2015 and would have major economic benefits. The main challenge for achievement of the global goal is to show that it can be reached in a cost-effective manner with existing interventions. This series of papers in The Lancet provides evidence that this goal is not only possible but also realistic with a small set of interventions directed towards whole populations and individuals who are at high risk. The total yearly cost of the interventions in 23 low-income and middle-income countries is about US$5.8 billion (as of 2005). In this final paper in the Series we call for a serious and sustained worldwide effort to prevent and control chronic diseases in the context of a general strengthening of health systems. Urgent action is needed by WHO, the World Bank, regional banks and development agencies, foundations, national governments, civil society, non-governmental organisations, the private sector including the pharmaceutical industry, and academics. We have established the Chronic Disease Action Group to encourage, support, and monitor action on the implementation of evidence-based efforts to promote global, regional, and national action to prevent and control chronic diseases.

Risk factors for early myocardial infarction in South Asians compared with individuals in other countries.

CONTEXT: South Asians have high rates of acute myocardial infarction (AMI) at younger ages compared with individuals from other countries but the reasons for this are unclear. OBJECTIVE: To evaluate the association of risk factors for AMI in native South Asians, especially at younger ages, compared with individuals from other countries. DESIGN, SETTING, AND PARTICIPANTS: Standardized case-control study of 1732 cases with first AMI and 2204 controls matched by age and sex from 15 medical centers in 5 South Asian countries and 10,728 cases and 12,431 controls from other countries. Individuals were recruited to the study between February 1999 and March 2003. MAIN OUTCOME MEASURE: Association of risk factors for AMI. RESULTS: The mean (SD) age for first AMI was lower in South Asian countries (53.0 [11.4] years) than in other countries (58.8 [12.2] years; P<.001). Protective factors were lower in South Asian controls than in controls from other countries (moderate- or high-intensity exercise, 6.1% vs 21.6%; daily intake of fruits and vegetables, 26.5% vs 45.2%; alcohol consumption > or =once/wk, 10.7% vs 26.9%). However, some harmful factors were more common in native South Asians than in individuals from other countries (elevated apolipoprotein B(100) /apolipoprotein A-I ratio, 43.8% vs 31.8%; history of diabetes, 9.5% vs 7.2%). Similar relative associations were found in South Asians compared with individuals from other countries for the risk factors of current and former smoking, apolipoprotein B100/apolipoprotein A-I ratio for the top vs lowest tertile, waist-to-hip ratio for the top vs lowest tertile, history of hypertension, history of diabetes, psychosocial factors such as depression and stress at work or home, regular moderate- or high-intensity exercise, and daily intake of fruits and vegetables. Alcohol consumption was not found to be a risk factor for AMI in South Asians. The combined odds ratio for all 9 risk factors was similar in South Asians (123.3; 95% confidence interval [CI], 38.7-400.2] and in individuals from other countries (125.7; 95% CI, 88.5-178.4). The similarities in the odds ratios for the risk factors explained a high and similar degree of population attributable risk in both groups (85.8% [95% CI, 78.0%-93.7%] vs 88.2% [95% CI, 86.3%-89.9%], respectively). When stratified by age, South Asians had more risk factors at ages younger than 60 years. After adjusting for all 9 risk factors, the predictive probability of classifying an AMI case as being younger than 40 years was similar in individuals from South Asian countries and those from other countries. CONCLUSION: The earlier age of AMI in South Asians can be largely explained by higher risk factor levels at younger ages.

Sib-recruitment for studying migration and its impact on obesity and diabetes.

BACKGROUND: Urban-rural comparisons are of limited relevance in examining the effects of urban migration in developing countries where urbanisation is due to growth of existing urban populations, expansion of urban boundaries, and rural in-migration. Cultural, genetic and life-style backgrounds of migrants and host populations further limit the value of rural-urban comparisons. Therefore we evaluated a sib-comparison design intended to overcome the limitations of urban-rural comparisons. METHODS: Using the framework of a current cardiovascular risk factor screening study conducted in Indian factories, we recruited the non-migrant rural sibs of migrant urban factory workers and the urban sibs of non-migrant factory workers. The response rate, completed interviews and examinations conducted were assessed. Adequacy of generic food frequency questionnaires and WHO quality of life questionnaire were assessed. RESULTS: All the urban factory workers and spouses approached agreed to be interviewed. Of the 697 participants interviewed, 293 (42%) had at least one rural dwelling sibling. Twenty (22%) siblings lived further than 100 km from the study site. An additional 21 urban siblings of non-migrant factory workers were also investigated to test the logistics of this element of the study. Obesity (BMI >25 kg/m2) was more common in rural sibs than urban factory workers (age adjusted prevalence: 21.1% (17.1 to 25.0) vs. 16.1% (11.9, 20.3). Diabetes prevalence (fasting plasma glucose greater than 126 mg/dl) was higher than expected (age-adjusted prevalence: 12.5% (22 out of 93) in urban migrants and 4.5% (8 out of 90) in rural non-migrant sibs. CONCLUSION: The sib-comparison design is robust and has been adopted in the main study. It is possible that simple urban-rural study designs under-estimate the true differences in diabetes risk between migrants and non-migrants.

Two-year outcomes in patients admitted with non-ST elevation acute coronary syndrome: results of the OASIS registry 1 and 2.

BACKGROUND: Acute coronary syndrome continues to have significant long-term morbidity and mortality. This study sought to compare baseline characteristics, practice patterns and clinical outcomes for patients with non-ST elevation acute coronary syndrome from a broad range of low-, middle- and high-income countries. METHODS AND RESULTS: We compared the data from a prospective registry of patients with non-ST elevation acute coronary syndrome involving 4615 patients from 65 centers in 8 low and middle income countries (OASIS registry 2) with those obtained from 7987 patients from 95 centers in 6 middle and high income countries (OASIS registry 1). Patients in the OASIS registry 2 were younger, were more often males and smokers, presented later to the hospital after symptom onset and had a lower prevalence of diabetes at admission [with the exception of India, which had the highest age-adjusted prevalence (39.1%)]. There were marked variations in the angiography and intervention rates during the hospital stay, but the uses of proven pharmacological therapies were comparable. The two-year mortality rates adjusted for baseline covariates ranged from 6.9% to 15%. Patients from China had the lowest two-year mortality rate (6.9%) and patients from India had the highest rate (15%). Combining the two registries, the covariate-adjusted rate of death or myocardial infarction did not differ across countries with in-hospital angiographic rates of > or = 50% (17.1%), 25-49% (16.7%) or < 25% (16.5%). However, the covariate-adjusted rates for subsequent myocardial infarction (7.6%, 9.2% and 10.8% respectively, p < 0.0001), refractory angina (21.3%, 27.7% and 35.4% respectively, p < 0.0001) and the composite of death, myocardial infarction or refractory angina (34.9%, 40.7% and 46.8% respectively, p < 0.0001) differed depending on the angiographic rates. CONCLUSIONS: Among the participating countries there was a marked heterogeneity in patient characteristics, coronary interventions, resulting in differences in the two-year composite rates of death, myocardial infarction and refractory angina among patients admitted with non-ST elevation acute coronary syndrome.

Impact of omega-6 fatty acids on cardiovascular outcomes: A review.

Poly unsaturated fatty acids (PUFAs) have usually been associated with beneficial health effects on early life and later life disease such as cardiovascular diseases (CVD). Emerging evidence, however, suggests that PUFA species (n-3, n-6) have differential health effects. N-6 PUFAs, in particular, have sparked a scientific debate regarding their role in human physiological processes. Current dietary recommendations for n-6 fatty acids have been based on animal studies, insufficient epidemiological evidence and mixed PUFA interventions, therefore, require reconsideration. This review has analyzed human epidemiological and interventional studies, published in the last five years, focusing on n-6 fatty acids' impact on CVD outcomes (CVD events, blood lipids, blood pressure, inflammation, oxidative stress/atherosclerosis). The evidence is mixed, with differential effects within the n-6 fatty acid series. These outcomes are also dependent on ethnicity and background health status. Further, data from developing countries are sparse, thus, well designed intervention trials and population based studies in developing country settings on specific n-6 fatty acid intake and health effects are desired.
