Filter by:Pregnant women with histories of depression are at high risk of depressive relapse during the perinatal period, and options for relapse prevention are limited. Mindfulness-based cognitive therapy (MBCT) has strong evidence among general populations but has not been studied among at risk pregnant women. This study is the first phase of a multi-phase project adapting MBCT for perinatal women (MBCT-PD). It is being conducted in a collaboration between the University of Colorado, Emory University, and Kaiser Permanente at Colorado and Georgia.
The project was undertaking by Qilu Hospital of Shandong University and other well-known hospitals in China. Aims at evaluating efficacy and safety of rhTPO in management of ITP in pregnancy.
Pregnant women with histories of depression are at high risk of depressive relapse/recurrence during the perinatal period, and options for relapse/recurrence prevention are limited. Mindfulness-based cognitive therapy (MBCT) has strong evidence among general populations but has not been studied among at risk pregnant women. This study is the second phase of a multi-phase project adapting MBCT for perinatal women (MBCT-PD).
Obstructive sleep apnea (OSA) is a risk factor for complications during pregnancy and current screening tools for OSA have not been shown to be reliable in pregnant women. The primary aim of this study is to develop a valid screening tool to identify at-risk pregnant women, so that they can be further evaluated and treated. Women with OSA may also be at risk for respiratory complications related to opiate administration for post-cesarean delivery pain. A secondary aim of this study is to evaluate post-operative minute ventilation in women who undergo cesarean delivery using a novel method of non-invasive minute ventilation monitoring.
Every day in Ghana, 47 babies are stillborn (SB) and 232 babies are born with low birth-weight (LBW) - many of whom will die in infancy or suffer lifelong consequences. Sleeping on the back during pregnancy has recently emerged in scientific literature as a potential risk factor for SB and LBW. In fact, one of the earliest studies to demonstrate this link was conducted in Ghana by investigators on this protocol. When a woman in mid-to-late-pregnancy lies on her back, her large uterus compresses one of the major veins that delivers blood back to her heart and may completely obstruct it. This may result in less blood being returned to her heart and less blood being pumped to her developing fetus. Such changes may negatively impact the growth of her fetus and, along with some other risk factors, may contribute to the death of her baby. The investigators have developed a device, 'PrenaBelt', to significantly reduce the amount of time a pregnant woman spends sleeping on her back. The PrenaBelt functions via a simple, safe, effective, and well-established modality called positional therapy. The purpose of this study is to determine the effect of the PrenaBelt on birth-weight and assess the feasibility of introducing it to Ghanaian third-trimester pregnant women in their home setting via an antenatal care clinic and local health-care staff. Data from this study will be used in effect size calculations for the design of a large-scale, epidemiological study targeted at reducing LBW and SB in Ghana and globally.
Back and right-sided sleeping position in pregnant women has recently emerged as a potential risk factor for low birthweight (LBW) and stillbirth (SB) in the medical literature. Assuming that sleep position in pregnant women is modifiable, the same literature has indicated that this risk factor is modifiable; however, there is no evidence that this risk factor is truly modifiable. The proposed link between back and right-sided sleeping position in a pregnant woman and LBW and SB of her baby is multifactorial; however, it ultimately implicates the woman's body position in causing compression of one of the large veins that brings blood back to her heart. This compression, along with other factors relating to the woman, her placenta, and her developing fetus, may result in decreased blood flow (nutrition and oxygen) to her developing baby, which, depending on the extent and duration, could result in LBW or SB of her baby. If the back sleeping position during pregnancy has a causative role in LBW and subsequently SB, the literature indicates that up to 17% of LBW and consequently 26% of SB could potentially be prevented by changing position to avoid back sleep. Note that 20 million LBW and 2.6 million SB occur each year worldwide. Positional therapy (PT) is a safe and effective intervention for preventing people who snore or people who's breathing pauses during sleep from sleeping on their back - a position that makes their condition worse. The most basic form of PT modifies a person's sleeping position by either: - Preventing them from sleeping on their back through restricting their movement, or - Rather than restricting movement, significantly reducing the amount of time they spend sleeping on their back by applying pressure points to their body while they are on their back, which eventually causes them to shift into a different position and avoid lying on their back. The purpose of this study is to evaluate the ability of a PT intervention to modify the position of pregnant women from their back and right side to their left side while they sleep in late pregnancy. This study will help determine whether this potential risk factor is modifiable by way of a PT intervention, and whether it is feasible to intervene to reduce or prevent back and right-sided position sleep in late pregnancy. Demonstrating that the sleeping position of pregnant women can be modified through use of a simple, inexpensive PT intervention may be one of the keys to achieving significant reductions in LBW and late SB rates in Canada and worldwide.
This is a study of pregnant women undergoing a cesarean delivery. It will compare their microcirculation before and after the anesthetic. Microcirculation means blood flow to the extremely small blood vessels in the body. It will also look at the differences in microcirculation of participants who receive an infusion of phenylephrine compared to participants who don't. The investigators hypothesize that spinal anesthesia will reduce the vascular density and proportion of perfused vessels.
The purpose of this study is to determine if the use of routine transvaginal cervical length ultrasound can be used to prevent preterm deliveries in twin gestations.
To determine the effect of a policy of early maternal-newborn infant discharge (12-24 hours) with a home visit on admission to the Level II/III nursery and hospital admissions and readmissions.
Fewer pregnant women achieve recommendations for physical activity (PA) (30 minutes of moderate PA 5 days of the week) as compared to non-pregnant women (15.8% to 26.1% respectively), and PA participation declines as pregnancy progresses. The benefits of PA during pregnancy are abundant to both the mother (e.g., reduced weight gain, lower risk of gestational diabetes) and the fetus (e.g., decreased fat mass, improved stress tolerance). Pregnancy represents a significant time in a woman's life in which she may be motivated to change her health behaviors due to concerns for the healthy development of the fetus and a quick return to pre-pregnancy weight. Hence, pregnancy represents a critical time to support women in PA participation. In our previous research, 94% of pregnant and postpartum women of varying socioeconomic statuses reported using the Internet for pregnancy and PA information. Despite some women increasing their PA participation as a result, most did not know if a website was reputable or reliable (i.e. evidence-based). Studies have reported that most online health information is unregulated and inaccurate. Further, women often receive inadequate PA information from physicians who are constrained by time and lack of knowledge about PA. Therefore, directing pregnant women to evidence-based websites via text messaging may provide a feasible approach to improve PA participation. PA participation in pregnant women is an ongoing challenge that warrants testing of innovative solutions. The purpose of this study is to determine the feasibility of using mobile phone text messaging to refer pregnant women to evidence-based websites for PA information to increase PA levels.
