To better understand the roles that hormones and experience play in infant survival and maternal behavior in a biparental primate species, we analyzed urinary estrone (E(1)C) and pregnanediol glucuronide (PdG) from 24 socially housed titi monkey (Callicebus cupreus) females over 54 pregnancies (N = 1,430 samples). Pregnancies were categorized according to whether the infant survived (N = 35) or...

[Purpose] The purpose of this single-center investigation was to study the impact of pregnancy on back pain and body posture. [Subjects] The subjects were 26 pregnant females. [Methods] Data were generated with a spine scanner (Diers(®) formetric 4D), trunk strength measurement (Diers(®) myoline), a numeric pain scale (0 to 10), and a biomechanical model. Parameters were compared during each tr...

The role of prenatal antibiotic exposure in the development of childhood wheezing is debated. We evaluated whether this association could potentially be explained by confounding factors.Antibiotic use in the first and third trimester of pregnancy, wheezing in children aged ≤18 months and confounding factors were assessed in singletons participating in the NINFEA (Nascita e Infanzia: gli Effetti...

Second trimester abortions constitute 10-15% of all induced abortions worldwide but are responsible for two-thirds of major abortion-related complications. During the last decade, medical methods for second trimester induced abortion have been considerably improved and become safe and more accessible. Today, in most cases, safe and efficient medical abortion services can be offered or improved ...

We evaluated the influence of maternal pre-pregnancy body mass index (BMI), based on reported pre-pregnancy weight and height, on blood pressure (BP) levels during pregnancy by using information from a prospective cohort of 1733 women recruited before 20 weeks' gestation. Maternal antenatal BP values were abstracted from medical records, and we evaluated the mean BP differences according to BMI...

BACKGROUND Maternal smoking during the third trimester reduces the birthweight of the full-term neonate. We assessed the relationship between the timing of exposure to maternal smoking, gestational period, weight and body length for both full-term and preterm neonates. METHODS A retrospective study with a questionnaire was conducted in 1194 infants who participated in the official medical exa...

INTRODUCTION Earlier studies in India have demonstrated an inverse relationship between physical activity and birth weight in rural women who had high levels of physical activity related to agricultural and domestic activities. There are no data on urban Indian women from a wide range of socio-economic backgrounds with varying levels of physical activity. This study assessed the role of differe...
