Filter by:This study seeks to understand the physical, physiologic and biologic features that predispose a woman to the development of obstructive sleep apnea once they are exposed to the cardiopulmonary and metabolic physiological changes of pregnancy. Knowing these specific predictive factors can help identify a population at risk and guide clinicians to develop suitable targeting screening strategies.
The goal of this pilot project is to utilize stable isotopically labeled vitamin D3 and state of the art mass spectrometric methodology to assess vitamin D dynamics during pregnancy in relation to relation to obesity and vitamin D binding protein genotype. At the conclusion of this study, the investigators will have obtained novel information on the absorption and utilization of vitamin D in women and the degree to which vitamin D utilization during pregnancy is impacted by genetic ancestry, vitamin D binding protein concentration and genotype and by excess adiposity.. The long-term goal is to better understand the unique metabolism of vitamin D during pregnancy.
The purpose of the study is to prospectively assess the prevalence of venous thrombosis in women hospitalized for Cesarean Section, vaginal delivery or extended antepartum hospitalization by using Compression ultrasound of the entire proximal venous system of the lower limb veins.
The purpose of the study is to test whether nutritional supplementation during pregnancy is associated with 1) improved maternal health during pregnancy; 2) improved infant birth and neurodevelopmental outcomes, and 3) whether the association between nutritional supplementation during pregnancy and infant outcomes is partially mediated by reductions in maternal perceived stress and stress reactivity during pregnancy.
The goal of Quarenta Semanas is to remove risk factors for preterm birth by linking women to prenatal care in the first trimester; supporting, educating and empowering women in pregnancy to reduce maternal stress and interrupt social, psychological, attitudinal and biological risk factors for preterm birth; and providing evidence-based, quality care that identifies and intervenes medically to treat underlying chronic and emergent conditions associated with preterm birth.
The aim of this study is to examine the effect of a supervised physical exercise program during pregnancy on fetoplacental growth.
This study is testing the hypothesis of whether continuous positive airway pressure (CPAP) therapy improves placental histopathology and secretory function. The main aims of the study are to identify shared mechanisms between obstructive sleep apnea and preeclampsia, both common highly morbid conditions.
Exposure to Household air pollution (HAP) from burning biomass fuels is responsible for an estimated 2.5 million premature deaths and 3.7% of the loss of disability-adjusted life years (DALY) every year in developing countries.52-54 Of all environmental risks, such as unsafe water, poor sanitation, climate change and lead exposure, HAP accounts for the most mortality and DALY.55 Despite the magnitude of the problems associated with HAP, research on its health effects has been hindered by lack of accurate data on exposure and health outcomes. There are few studies available that report HAP exposures and development of adverse pregnancy outcomes from households using biomass fuels.
The link between precarious situations and health conditions are more described in previous study. Precarious situations are more frequent and complex especially in rural areas. There are recognized like a risk factor of complications during pregnancy and delivery. It's necessary to describe antenatal cares for rural women in precarious situations to prevent those situations, to understand their difficulties in order to reduce inequalities and health spending. The aim of the PRUGNANCY study is to understand the difficulties of rural parturient women and the strategies developed to overcome them. Recognized earlier precarious situations and valorized General Practitioners and restore them to the follow-up or parturient women.
This project randomizes two different screening strategies for diabetes in pregnancy, among a study population of over 17,500 pregnant women and their babies (over 35,000 total) in a large diverse health maintenance organization (HMO), to determine how diagnosis and treatment based on these two strategies in routine clinical care affects complications for the baby and the mother.
