Some studies on child labor have shown that, at the level of the household, greater land wealth leads to higher child labor, thereby casting doubt on the hypothesis that child labor is caused by poverty. This paper argues that the missing ingredient may be an explicit modeling of the labor market. We develop a simple model which suggests the possibility of an inverted-U relationship between lan...

  Preterm labor is one of the major causes of neonatal mortality and morbidity. Despite significant improvement in care for premature neonates, the most suitable and inexpensive treatment is prevention of preterm labor by inhibiting uterine contractions. The aim of this research is to obtain scientific evidence for the relaxant effect of ketotifen on the rat uterus and to provide the preclinica...

BACKGROUND While tocolytic therapy can halt the process of delivery, some patients return before the 37th week of pregnancy with recurrence of preterm labor signs. OBJECTIVES This study was designed to evaluate the efficacy of progesterone in the prolonging of gestation and reduction of neonatal complications. MATERIAL AND METHODS In a clinical trial in 2010, 110 singleton pregnant women ad...

Preterm birth is the major cause of perinatal morbidity and mortality in the developed world, and spontaneous preterm labor is the commonest cause of preterm birth. Interventions to treat women in spontaneous preterm labor have not reduced the incidence of preterm births but this may be due to increased risk factors, inclusion of births at the limits of viability, and an increase in the use of ...

The role of the matrix metalloproteinases (MMPs) in the decidua, fetal membranes and amniotic fluid (AF) has been receiving more and more attention. The MMPs are not only important intermediaries in pathological processes leading to preterm labor but it seems that they also play a crucial role in the activation of labor at term. During normal gestation MMP-1, -2, -3, -7 and -9 are found in the ...

There is little evidence in Brazil on the impact of child labor on health status in adulthood. This study aimed to investigate trends in child labor in Brazil and estimate the long-term effects of child labor on the health of Brazilian adults, using nationally representative databases (Brazilian National Household Sample Survey) from three different years (1998, 2003, and 2008). The models were...

Child Labor Variation by Type of Respondent: Evidence from a Large-Scale Study This study uses a nationally representative survey to analyze a key survey design decision in child labor measurement: self-reporting versus proxy interviewing. The child/proxy disagreement affects 20 percent of the sample, which translates into a 17.1 percentage point difference in the national rate of child labor b...

Labor pain is one of the most severe pains. Labor is a complex and individual process with varying maternal requesting analgesia. Labor analgesia must be safe and accompanied by minimal amount of unwanted consequences for both the mother and the child, as well as for the delivery procedure. Epidural analgesia is the treatment that best meets these demands. According to the American Congress of ...
