TL;DR: High coverage of essential interventions did not imply reduced maternal mortality in the health-care facilities the authors studied, and the maternal severity index (MSI) had good accuracy for maternal death prediction in women with markers of organ dysfunction.

TL;DR: The management of the disease is a key determinant in which factors relating to the mother and the health services are strongly related, and untimely care seeking, difficult access and inadequate disease treatment are revealed.
Abstract: A population-based case control study was conducted to ascertain whether the process of primary care can be a determinant of infant mortality due to Acute Respiratory Infection (ARI). Cases were 118 infants who died from ARI, individually matched with 118 infants who suffered an ARI episode and recovered. Information was gathered through interviewing mothers. Study variables were assembled into five subsets: children's characteristics; mothers' characteristics; access to medical services; process of primary care, and; sociodemographic variables. An index per subset was built to analyze the independent influence of each on ARI death risk. The index was constructed upon the weighted sum of the adjusted odds ratios (OR) within each subset. Then, the values of each index were collapsed into high/low values with the 50 percentile as a cut-off value. Next, by means of a conditional logistic regression procedure, an explanatory model of ARI mortality was obtained. The final multivariate model included the indexes that showed an independent effect: I) Process of care (OR 9.68, CI 95% 3.59-26.1): inadequate referral, attention provided by more than one physician and being attended by a private physician; II) children's characteristics (OR 7.22, CI 95% 2.35-22.2): perinatal history, lack of breast-feeding and incomplete immunization scheme; III) access to medical services (OR 5.27, CI 95% 2.02-13.7): geographic and economic barriers, lack of confidence in public health services, and; IV) mothers' characteristics (OR 4.03, CI 95% 1.18-13.8), mainly represented by untimely care seeking. We conclude that the management of the disease is a key determinant in which factors relating to the mother and the health services are strongly related. Our study reveals untimely care seeking, difficult access and inadequate disease treatment as important factors which deserve careful attention in the future. We also confirm the importance of biological determinants previously described. A main strategy to reduce infant mortality due to ARI should be to encourage training of primary care physicians, including private practitioners, focused on providing effective case management and emphasizing the education to mothers.

TL;DR: The means by which primary care improves health have been identified, thus suggesting ways to improve overall health and reduce differences in health across major population subgroups.
Abstract: Evidence of the health-promoting influence of primary care has been accumulating ever since researchers have been able to distinguish primary care from other aspects of the health services delivery system. This evidence shows that primary care helps prevent illness and death, regardless of whether the care is characterized by supply of primary care physicians, a relationship with a source of primary care, or the receipt of important features of primary care. The evidence also shows that primary care (in contrast to specialty care) is associated with a more equitable distribution of health in populations, a finding that holds in both cross-national and within-national studies. The means by which primary care improves health have been identified, thus suggesting ways to improve overall health and reduce differences in health across major population subgroups.

TL;DR: Between 2003 and 2009, haemorrhage, hypertensive disorders, and sepsis were responsible for more than half of maternal deaths worldwide, and more than a quarter of deaths were attributable to indirect causes.

TL;DR: This new edition of Ann Bowling's well-known and highly respected text is a comprehensive, easy to read, guide to the range of methods used to study and evaluate health and health services.
Abstract: This new edition of Ann Bowling's well-known and highly respected text has been thoroughly revised and updated to reflect key methodological developments in health research. It is a comprehensive, easy to read, guide to the range of methods used to study and evaluate health and health services. It describes the concepts and methods used by the main disciplines involved in health research, including: demography, epidemiology, health economics, psychology and sociology.The research methods described cover the assessment of health needs, morbidity and mortality trends and rates, costing health services, sampling for survey research, cross-sectional and longitudinal survey design, experimental methods and techniques of group assignment, questionnaire design, interviewing techniques, coding and analysis of quantitative data, methods and analysis of qualitative observational studies, and types of unstructured interviewing. With new material on topics such as cluster randomization, utility analyses, patients' preferences, and perception of risk, the text is aimed at students and researchers of health and health services. It has also been designed for health professionals and policy makers who have responsibility for applying research findings in practice, and who need to know how to judge the value of that research.

TL;DR: The effectiveness of a range of interventions that include diet or physical activity components, or both, designed to prevent obesity in children is evaluated to determine overall certainty of the evidence.
Abstract: The current evidence suggests that many diet and exercise interventions to prevent obesity in children are not effective in preventing weight gain, but can be effective in promoting a healthy diet and increased physical activity levels.Being very overweight (obese) can cause health, psychological and social problems for children. Children who are obese are more likely to have weight and health problems as adults. Programmes designed to prevent obesity focus on modifying one or more of the factors considered to promote obesity.This review included 22 studies that tested a variety of intervention programmes, which involved increased physical activity and dietary changes, singly or in combination. Participants were under 18 and living in Asia, South America, Europe or North America. There is not enough evidence from trials to prove that any one particular programme can prevent obesity in children, although comprehensive strategies to address dietary and physical activity change, together with psycho-social support and environmental change may help. There was a trend for newer interventions to involve their respective communities and to include evaluations.Future research might usefully assess changes made on behalf of entire populations, such as improvements in the types of foods available at schools and in the availability of safe places to run and play, and should assess health effects and costs over several years.The programmes in this review used different strategies to prevent obesity so direct comparisons were difficult. Also, the duration of the studies ranged from 12 weeks to three years, but most lasted less than a year.
