Filter by: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.
The WP200 and/or WP200U will be compared with a PSG system which is a digital physiological recorder system, cleared for use for clinical sleep studies. The manual scoring of the PSG data, performed by a trained and authorized scorer, according to the AASM (American Academy of Sleep Medicine) guidelines, serves as a "gold standard" for all determinations of efficacy.
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.
Amongst adolescents, there is a gap that widens with age between recommended sleep duration and actual sleep time. Due to this gap, bodily and mental functions such as those related to the metabolic and immune systems, performance, memory, school achievement and creative ability can be harmed. Moreover, lack of sleep involves an increased risk of accidents and injuries, behavior problems and reduced quality of life. Biological factors that explain changes in sleep patterns include delays in the circadian timing system and in the homeostatic system that regulate sleep and wakefulness. These changes cause a growing and continuous delay in sleep phase during adolescence. In addition, a number of environmental factors affect sleep patterns: variables such as early school start time, increased homework assignments, after-school activities, lack of parental demand for adequate sleep hours, and increased "screen time," or use of electronic media, including television, computer games, internet and cellular phones. Based on the Parental Style model, the authoritative parenting style is characterized by parents setting high demands on their children on the one hand and displaying high levels of responsiveness to their children on the other. The authoritarian parenting style is characterized by parents setting high demands on their children on the one hand yet displaying low levels of responsiveness to their children on the other. The permissive parenting style is characterized by parents setting low demands on their children and displaying high levels of responsiveness to their children. In several investigations, the authoritative parenting style has been shown to have a positive influence on child development, academic achievement and psychosocial competency, and promoted healthy behaviors in adolescents, such as good eating habits, increased physical activity and a decrease in risky behaviors such as smoking, alcohol abuse, extreme diets and early sexual behavior. The Conceptual Model views parents as the sole agents of change in their children's life, and focuses on the power of personal example, environmental changes and promotion of the authoritative parental style. The main aim of this research is to evaluate the effectiveness of an intervention program that deals with increasing parents' awareness of the changes that characterize adolescents and encourages the authoritative parental style based on the Parenting Style Model.
This pilot randomized controlled trial examined the feasibility, acceptability and effectiveness of an intervention to improve sleep quality and decrease fatigue levels in children with a diagnosis of ALL, during maintenance treatment. Families were randomized to usual care or the intervention. The intervention included a sleep hygiene and relaxation education session with a nurse practitioner, literature for home, two story books, and a follow-up phone call. Self-reported measures were used in addition to actigraphy to measure children's quality and quantity of sleep.
Participants from the Fatigue and Lifestyle Physical Activity and SLE Study will be approached to enroll in a 6 week pilot intervention. This study will look at the barriers and facilitators to increasing physical activity, improving dietary/nutritional intake, and improving sleep.This study will offer support and information for people with SLE to increase their physical activity, improve their dietary/nutritional intake, and improve their sleep and will utilize a smartphone application to self-monitor changes in these behaviors.
The investigators are conducting a cluster randomized trial in a sample of 63 internal medicine (IM) training programs that are randomly assigned to either the current duty hour standards or less restricted flexible duty hour standards. The trial includes a main protocol in which all randomized IM programs participate and two substudies. "Time and Motion" and "Sleep and Alertness", each conducted at a subset of IM programs and focusing on more detailed data collection at the intern level. The main protocol will examine patient safety and costs as well as quality of education. The "Time and Motion" substudy examines additional educational outcomes. The "Sleep and Alertness" substudy examines intern sleep time and alertness.
The main objective of the study is to identify the determinant of sleep characteristics of obese patients attempting a tertiary clinical center for obesity management, including bariatric surgery. More accurately the questions addressed are: - What are the determinants of the sleep habits (sleep duration, chronotype) and of their evolution - What are the determinants of sleep breathing disorders (sleep apnea, obesity hypoventilation syndrome) and of their evolution
The purpose of this study is to determine if aerobic exercise training can serve as comprehensive palliative care, whereby enhancing cardiovascular fitness, mitigating depressive symptoms and augmenting sleep while bolstering health related quality of life in youth with Crohn's Disease and Ulcerative Colitis.
Bedtimes and wake-up times vary from person to person. The aim of this research is to examine the associations between sleep habits and metabolism in healthy people. In this study, the investigators will collect information on sleep-wake habits and how the body uses energy.
