Filter by: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.
Stress is an important determinant of pregnancy health behaviors, maternal physiology and maternal-infant health outcomes. The purpose of this study is to explain the relationship between dimensions of lifetime stress and the stress hormone cortisol in pregnant women. Additionally, the study will examine how coping styles help pregnant women to better manage stress and improve their health behaviors to achieve the goal of having a healthy baby.
Background: Obesity increasingly affects young women and contributes to increased maternal, fetal and neonatal complications. Maternal obesity contributes to the subsequent development of childhood obesity not only through social and environmental mechanisms but also through biological processes referring to the original concept of the developmental health and disease. Data suggest that management during pregnancy through nutrition counseling and adequate physical activity will help to break the familial vicious circle of obesity. To help program to be effective it is important to understand the factors that modulate participation. However, few studies have been conducted to assess the determinants that influence participation. Goal: The main objective is to analyze 15 factors that influence participation in a program combining physical activity and nutritional counseling among pregnant women with BMI ≥ 25 kg/m2. Secondary objectives are : - to identify the data that influence adherence and to show that assiduous women will have a better control of weight gain and a reduction of maternal and fetal complications. - to understand the biological mechanisms involved Strategy and method: A prospective research evaluating the participation in an educational program, including nutritional support and adequate physical activity, will be offered to overweight and obese pregnant women. The program will last 12 weeks, and will include three workshops on diet of the pregnant and lactating women, and the young child. Physical activity sessions will be offered once a week. Fifteen independent variables likely to influence participation will be analyzed. The association between participation and the risk of maternal and fetal pregnancy complications related to obesity will be analysed. Meanwhile, more fundamental research will be considered to determine of the biological factors involved.
The main goal for this study is to assess concerns and barriers to research participation by pregnant women through an anonymous online survey (www.pbrc.edu/ParticipateWhilePregnantSurvey).
Background: Nutrition challenges follow bariatric surgery can intensify during pregnancy and may have a crucial effect on fetus. To the best of the investigators knowledge, the effect of nutritional counseling on improvement of maternal diet quality and eating habits among post- bariatric pregnant women has not been evaluated. Objective: study aims to expand the existing limited knowledge in respect to post bariatric pregnant women's eating habits and quality of food intake, and to investigate the impact of nutrition counseling on these factors. Design: This is a controlled clinical trial comparing post Laparoscopic sleeve gastrectomy (LSG) pregnant women who received nutritional counseling with age-matched control healthy pregnant women. Counseling will focus on improving quality of food consumption, eating habits and behavioral changes in order to improve the mother and the fetus' nutritional status Nutritional data and eating behavior will be obtained using 24 hours recall dietary records and the Family Eating and Activity Habit Questionnaire (FEAHQ).
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.
This study aims to investigate the impact of serum progesterone concentrations on the day of embryo transfer in egg donation cycles under hormonal replacement therapy. As secondary outcomes, the investigators will investigate if endometrial volume measured by three-dimensional (3D) ultrasound on the day of embryo transfer is related with progesterone levels and with chances of pregnancy.
The aim of the study is to evaluate the effect of vaginal lactoferrin administration on amniotic fluid PGE2 level and MMP-TIMP system in women undergoing genetic amniocentesis. Two groups of patients will be prospectively enrolled: not treated with lactoferrin and treated with vaginal lactoferrin 4 hours prior to mid-trimester genetic amniocentesis.
The purpose of the present study was to measure the effect of proprioceptive training, short-term, on dynamic postural balance during pregnancy and after 8 weeks of follow-up. Thirty-nine pregnant women were randomized to either the intervention group(n=20) , which would perform proprioceptive exercise, or the control group(n=19, no intervention) .
Investigators want to investigate if the Lactobacillus Reuteri (probiotic bacteria) given to pregnant women can be found in different maternal compartments and in the first stool and oral swab collected immediately after birth of a newborn delivered by cesarean delivery. Investigators also want to explore if exposure to this Lactobacillus Reuteri alters the level of inflammation in different compartments of the mother and the infant.
