BACKGROUND: The rate of preterm birth has been increasing worldwide, including in Brazil. This constitutes a significant public health challenge because of the higher levels of morbidity and mortality and long-term health effects associated with preterm birth. This study describes and quantifies factors affecting spontaneous and provider-initiated preterm birth in Brazil. METHODS: Data are from the 2011-2012 "Birth in Brazil" study, which used a national population-based sample of 23,940 women...

The economists interest in the relationships between health and work by studying three relations: the negative effect of the poor health on the position on the labor market, the positive influence of work on health but also the role of hard working conditions and employment on health status. If the international literature is plentiful, the French literature is more recent. In France, the effects of health events are more penalizing on the professional career when they onset in second part of career inviting in the implementation of a premature prevention in companies...

BACKGROUND: Chorioamniotic membrane separation (CMS) is a rare finding that is commonly preceded by invasive fetal procedures. The presence of CMS can also be associated with uncommon maternal or fetal conditions as well as preterm delivery, amniotic band syndrome, umbilical cord complications, and fetal and neonatal death. It is classified as a high-risk antepartum condition due to the significant fetal morbidity and mortality that may ensue. CASE REPORT: A 40-year-old gravida 5 para 1212 at 35 weeks presented for antepartum fetal testing...

INTRODUCTION: Neonatal respiratory distress (NRD) is a main cause of neonatal morbidity and mortality in developing countries. Early detection of its risk factors and early treatment of its etiologies are major challenges. However, few studies in developing countries have provided data needed to tackle it. We aimed to determine the prevalence, predictors, etiologies and outcome of NRD in a tertiary health care centre of Cameroon. METHODS: We analyzed the hospital files of all newborns admitted to the Neonatal unit of Douala General Hospital from 1(st) January 2011 to 28(th) February 2013...

OBJECTIVE: Müllerian anomalies are associated with increased risk of miscarriage, intrauterine growth restriction (IUGR) and preterm birth. While a commonly implicated cause is restricted expansion of endometrial cavity, alternatively it could be due to abnormal placentation. We sought to examine clinical and histopathologic factors associated with preterm delivery in women with Müllerian anomalies. STUDY DESIGN: One hundred and eleven singleton pregnancies in 85 women were analyzed retrospectively...

Social security system currently faces a number of difficulties arising of changes in the demographic structure of societies, like the decrease in fertility, lengthening of life expectancy, and unfavorable change in the proportion of the population receiving retirement benefits to the population in working age. In result, social security systems are being subjected to transition aimed at securing their financial stability, part of which is a tendency to rise the retirement age and eliminate all the incentives to prematurely exit the labor market...
