Filter by:This study utilizes infusions of kisspeptin in healthy women to isolate the impact of kisspeptin on beta-cell responsivity assessed by the mixed meal tolerance test.
This clinical trial is a safety and feasibility study to assess the performance of an artificial pancreas (AP) system using the Zone Model Predictive control (Zone-MPC) and Health Monitoring System (HMS) algorithms embedded into the iAPS platform for pregnant patients with type 1 diabetes (T1D).
The goal of this pilot project is to test the feasibility and potential efficacy of the evidence-based mHealth app (BumptUp) for improving physical activity and subsequent health outcomes (i.e. obesity, hypertension, insulin resistance) among pregnant and postpartum women in a rural community. In order to accomplish this goal, feasibility of the intervention protocol will be tested by the assessment of recruitment (how many participants eligible per month), retention (% of women who complete the study protocol), adherence to intervention (% of women who utilize the app), and acceptability (survey and one-on-one exit interviews) during pregnancy and postpartum. Potential efficacy will be determined by examining trends in data on physical activity levels (achieving the goal of 150 minutes per week of physical activity (surveys and accelerometry)) between groups. Other secondary outcomes will also be assessed: weight status, body composition, blood pressure, insulin resistance, fitness levels, mental health, and infant anthropometrics. Clinical hypotheses: 1. The mHealth program will be feasible as evidenced by high rates of enrollment, retention, and adherence, moderate-to-high levels of satisfaction, and low participant burden. 2. The mHealth intervention will show promise towards improving physical activity levels and other secondary outcomes in pregnant and postpartum women in a rural community.
Yoga has received considerable attention for its potential therapeutic benefits over the past decades and it gradually became object of scientific scrutiny. There is currently extensive literature supporting its use as a non-pharmacological tool for managing a variety of medical problems. A few studies have also explored potential beneficial effects of practising yoga during pregnancy on maternal and neonatal outcomes. An association between prenatal yoga and decreased incidence of fetal growth restriction, preterm delivery, and labor abnormalities resulting in operative delivery have been reported. Exact mechanisms by which yoga could improve perinatal outcomes have not been elucidated yet. One of such mechanisms could be the positive effect of yoga on autonomic nervous system (ANS). Maternal cardiovascular system undergoes profound changes during pregnancy and ANS plays a central role in adaptation to pregnancy-related hemodynamic changes. Increase in peripheral vascular resistance that characterises hypertensive disorders in pregnancy with fetal growth restriction is mediated by substantial increase in sympathetic vasoconstrictor activity. Effects of yoga on ANS outside of pregnancy have already been investigated in several studies. Heart rate variability (HRV) indices, used as a one of proxy measures for ANS activity, showed significant shifts towards parasympathetic dominance following yoga sessions. Another objective means of assessing ANS activity is measurement of phase synchronisation between cardiovascular and respiratory systems following acute challenge. The higher the cardiorespiratory synchronisation after acute challenge is, the higher is the ability of ANS to flexibly adapt to challenge. The objectives of the study are: I. To examine whether there is a short-term shift in autonomic balance to the parasympathetic branch of the ANS and ability of the cardiovascular and respiratory respiratory systems to flexibly adapt to acute psychological challenge following sessions in pregnancy. II. To investigate potential long- term effects of yoga practice during pregnancy on HRV and cardio-respiratory synchronisation following acute psychological challenge.
Myelomeningocele is a malformation with high incidence, and it consists in a neural tube defect. Fetal intrauterine surgery is an alternative for correction, and it improves the prognosis of the fetus, but has an increased risk of maternal complications and premature labor, as it can occur due to uterine stimulation. It is therefore essential that tocolysis is performed before, during and after surgery, and the most commonly used tocolytics are terbutaline and atosiban. Terbutaline has no specificity and may have several adverse effects such as maternal acidosis.
The objective of this study is to compare, through a multicentric randomized trial, the impact of two pH values in the embryo culture medium on the clinical results of In Vitro Fertilization (IVF) process and especially the impact on live birth delivery rate.
Owlet Baby Care, Inc. has developed a wearable fabric band pregnancy monitor, to be worn around the maternal abdomen incorporating electrocardiogram sensors. The purpose of this proposed test is to collect overnight "at-home" fetal ECG recordings on women during the second half of pregnancy using the pregnancy monitor.
This study aims to evaluate different screening strategies to decrease the burden of Neisseria gonorrhoeae (NG), Chlamydia trachomatis (CT) and Trichomonas vaginalis (TV) among pregnant women, and reduce adverse birth outcomes. In turn it aims to evaluate the cost per pregnant woman screened and treated, cost of adverse birth outcomes, and cost-effectiveness per sexually transmitted infection (STI) and disability-adjusted life-year (DALY) averted. Furthermore, this study will incorporate a vaginal microbiome sub-study aimed to investigate the relationship between the vaginal microbiome and persistent Chlamydial infections in pregnant women. Aim 1 and 2: The intervention includes diagnostic testing at a woman's first antenatal care visit using the Xpert® platform with same-day treatment for Neisseria gonorrhoeae, Chlamydia trachomatis and Trichomonas vaginalis infection with either a test-of-cure three weeks post-treatment (arm 1) or a repeat test at 30-34 weeks gestation (arm 2) compared to the standard of care, i.e. syndromic management (arm 3). Aim 3: Case-control study to investigate role vaginal microbiome in STI treatment outcomes
Purpose: To investigate the growth and development status for children of 1 ~ 3 years old in China, and to explore and analyze the influencing factors of infant growth. Mother's health status would also be investigated simultaneously. Methods and analysis: This is a multicenter prospective cohort study. Participants were all from the Chinese Pregnant Women Cohort Study (CPWCS), which is a multicenter prospective cohort study we conducted before. In simple terms, pregnant women during the first trimester (5~13 weeks' gestational age) were included from 25 July 2017 to 26 November 2018. Related information were collected by electronic self-administered questionnaire, including general information, environmental exposure assessment, physical activity assessment, dietary and nutritional assessment, depression assessment, sleep quality assessment and economic burden assessment. Subsequently, objective medical information, obstetric and neonatal outcomes were collected through hospital information system (HIS). To further assess the mothers' and infants' health status, a new multicenter prospective cohort study, including more than 1000 participants of the CPWCS from 5 hospitals of 5 different provinces in China, will be conducted. Through the electronic self-administered questionnaire surveys and laboratory testing methods, information about infants' feeding, sleeping, defecating, oral health, early development and common allergic diseases will be collected. And we will also assess mothers' current health habits and status, such as sleeping, diet, anxiety, physical activity, and oral health. SAS statistical software will be used for data analysis. Ethics and Dissemination Permission for the study was obtained from Chinese Academy of Medical Sciences and Peking Union Medical College. Ethics approval was obtained from the Ethics Review Committee of Department of Scientific Research, School of Basic Medicine, Peking Union Medical College, Beijing, China. The results will be published in peer-reviewed journals or disseminated through conference presentations.
Management of fetal macrosomia is based on a suspicion of macrosomia (no certainty before birth). This management is an artificial induction of labour for an earlier delivery and therefore a lower fetal weight gain. Several studies have already shown that ultrasound performed during the third trimester of pregnancy was not a perfect tool for this screening.
