Filter by:This is a prospective, multi‐center observational study designed to compare the test results of the Verinata Health Prenatal Aneuploidy Test to results of conventional prenatal screening for fetal chromosome abnormalities in 'all-risk' pregnancies.
There is increasing evidence that psychosocial factors may affect health by means of biological effects and changes in behavioral health. Observational studies suggest an association between low levels of one long chain n-3 fatty acids, DHA (docosahexaenoic acid), after pregnancy and the occurrence of postpartum depression (PPD). This is an observational cohort with 4 waves of follow-up and a nested clinical trial with pregnant women residing in the city of Rio de Janeiro. The general objective is to describe the magnitude and identify factors associated to common mental disorders (CMD) during pregnancy and postpartum giving emphasis to maternal nutritional status. Main specific objectives: 1. To evaluate the effect of CMD in the pattern of occurrence of selected maternal and child outcomes (inadequacy of gestational weight gain, postpartum weight retention, low birthweight, small for gestational weight and prematurity), considering the effect of other determinant factors, and 2. To evaluate the effectiveness of daily omega-3 doses (fish oil) in preventing PPD.
S. mutans counts have been found to be high in women with high level of untreated caries. In Pakistan 95% of all carious lesions are untreated that is an alarming situation. A majority of mother's have high level of caries and pose an increase risk of vertically transmitting it to their children. Therefore, the aim of this study is to determine the effect of A Traumatic Restorative Treatment(ART) in reducing S. mutans count in pregnant women and indirectly reduce the vertical transmission of S. mutans to their children so that ART as a preventive program may be provided and promoted in periurban areas where there is a lack of accessibility to oral health care.
Periodontal diseased during pregnancy are associated with many unpleasant prenatal consequences including preeclampsia, preterm labor, and low birth weight (LBW). Treatment of such diseases and observance of oral and dental hygiene may to some large extent prevent such consequences. Unfortunately previous studies have shown that pregnant women have very little knowledge of oral and dental health implications. Given the fact that pregnancy my be a unique opportunity to initiate correct hygienic behaviors in young women, this paper has focused on studying the effects of oral and dental health education during pregnancy. In this single blind clinical trial study,140 pregnant women receiving care from Khaje Rabi Regional Health Center in Mashhad city who were members of a community based multi-center were chosen by systematic clustering methods and randomly allocated into test and control groups. After intervention, two questionnaires were completed for demographic and pregnancy details of the participants. Knowledge, health belief and health behavior were assessed before intervention. The test group had two educational sessions lasting 1 hour, focused on oral and dental health and especially on oral and dental health during pregnancy. women in the control group received no education. Knowledge, health belief and health behavior were assessed immediately after and one month after intervention of all participants. Analysis of data was done using SPSS, t-test and chi-square tests.
Hypothesis : Vitamin D serum concentration is decreased in the first trimester in pregnant women who will develop preeclampsia in the second or third trimester compare to a control group Primary purpose : To determine the vitamin D status in the first trimester in a large population of french pregnant women in order to evaluate the importance of the vitamin D deficiency in France and correlate this deficiency with preeclampsia
The investigators will conduct an educational intervention for pregnant women who are planning to breastfeed to promote exclusive breastfeeding and to increase the duration of breastfeeding.
The purpose of this study is to understand how differences in the nutritional status and concentration of hormones and cytokines associated with cachexia in HIV+ and HIV- pregnant women living in a semi-rural and rural region of northern Tanzania affect fetal growth, pregnancy outcomes and early infant health and development. The study hypothesis is that HIV+ women will have worse nutritional status and a greater degree of cachexia which will negatively impact fetal growth, pregnancy outcomes and early infancy health and development.
The study will use a comprehensive behavioral intervention adapted for pregnant women to change dietary intake, eating behavior and physical activity. The central hypothesis of this study is that the intervention will reduce excess gestational weight gain and achieve clinical and metabolic benefits in obese and overweight pregnant women and their infants over the first year of life.
The prevalence of maternal overweight and obesity has nearly doubled in the United States since 1976. In 2004-2005, 42% of pregnant women had body mass index (BMI) above 25 versus 23% in 1993. Most American women are overweight/ obese (OW/OB) at conception, especially within certain racial, ethnic, and lower socioeconomic groups leading to increased adverse maternal and birth outcomes. This study will recruit, randomize and test in 300 ethnically diverse OW/OB pregnant women a behavioral intervention aimed at controlling gestational weight gain (GWG) through recommended diet, activity and lifestyle changes that are to be maintained postpartum. Outcomes include anthropometric (height, weight, percent body fat) metabolic (blood pressure, fasting glucose, insulin, HbA1c, lipids and C-reactive protein) and behavioral measures (diet. physical activity, sleep and stress). In addition, babies will be measured for length, weight and percent body fat. The goal is to limit excessive gestational weight gain through improved maternal lifestyle that can be maintained and modelled for the family post partum and beyond.
The intraocular pressure in the human bulbus requires that the "wall" of the eye shows a certain (bio)mechanical strength. The human cornea represents the anterior portion of this wall. Since several years, there is a growing interest in the ophthalmological community for identifying factors modulating the biomechanical stability of the human cornea. Reasons are twofold: advances in keratoconus research and the increasing numbers of refractive laser surgery procedures with (correspondingly) increasing numbers of complications due to non-respecting the limits of corneal biomechanics. There is evidence that oestrogen, but also thyroïd hormone changes have a major impact on corneal biomechanics. A number of recent observational studies have reported on keratoconus and refractive laser surgery patients with decompensating biomechanics during pregnancy. Both hormones also show physiological changes during pregnancy and little is known about the impact of these physiological changes on the human cornea. The aim of this study is to establish baseline values for physiological changes in the human cornea during pregnancy.
