Filter by:This 5-year prospective, observational study will: (1) determine the individual, social, and environmental predictors of sleep duration, quality, latency, efficiency, timing and regularity in African American smokers, (2) quantify the prospective relationship between multiple metrics of sleep with tobacco use, such that a sleep phenotype of risk for smoking is defined, and (3) examine the extent to which short sleep (<7 hrs) and other unhealthy sleep metrics, predicts lung function through smoking behaviors and inflammation, in 480 African Americans at risk for advancing COPD (GOLD Stage 0-2 and current smoker). Study subjects will be recruited via Temple Health System sites. Following eligibility screening, initially eligible subjects will provide written study consent and complete an in-home sleep assessment to rule out the exclusionary moderate-severe sleep apnea and other sleep disorders. Consenting and eligible subjects will be entered into the study and across the 60-month data collection period, complete 8 assessments: 4 annual clinical based assessments, interspersed by 4 mid-year, phone-based, self-report assessments.
Goal of this project is to investigate whether increases in inflammation that result from common patterns of restricting sleep on week nights and catching up on sleep over the weekend are caused by disruption in the newly discovered inflammatory resolution pathways. These pathways are crucial in the active termination of the inflammatory response, and their disruption may contribute to ongoing unresolved inflammation, which has been observed not only during periods of sleep restriction, but also after recovery sleep has been obtained. If the hypothesis is true, it is possible that increasing the body's natural production of endogenous, inflammatory resolution mediators may provide a non-behavioral strategy to limit the inflammatory consequences in those undergoing periods of sleep restriction with intermittent recovery sleep.
Objective The objective of the current trial is to investigate the effect of perioperative sleep and circadian rhythm on the natural course of survival among patient diagnosed with colorectal cancer. Concurrently, outcome measures like depression, fatigue, quality of life, and co-morbidity will be measured continuously in the short-, intermediate- and long-term period following diagnosis. The a-priori hypothesis is that preoperative sleep and circadian disturbances is a prognostic marker of reduced overall survival. Likewise, preoperative sleep-wake disturbances at baseline are expected to result in overall universally reduced quality of life, increased depression and fatigue. Furthermore, development of sleep-wake disturbances in the postoperative period as compared to preoperative sleep-wake rhythm is expected to a prognostic marker of negative outcomes. Target and study population The study population are all patients diagnosed with colorectal cancer in Region Zealand recruited consecutively from the trial initiation until study end each patient with an intended 5 year follow-up period. All available cases will be included in the trial. Study design The study will be an observational prospective cohort study applying a longituditional repeated measure design. Exposures and outcomes of interest The primary outcomes in the trial are sleep and circadian outcomes measured via actigraphy in the perioperative period. Furthermore, cancer related survival and overall survival in the 5 year follow-up period is considered primary outcomes. Secondary outcomes consist of consecutively measured depression, fatigue, quality of life, follow-up treatment and co-morbidity. Exposure variables are primary related to the cancer, i.e. cancer stage, surgical treatment, oncological treatment, baseline co-morbidity and pharmacological treatment. Some of the secondary outcomes could be expected to serve as confounding or mediating factors. Meaningful control for confounding will in the analysis phase be cancer stage and baseline sleep-wake rhythm status. Sampling methods All available cases will be sought included in the trial. No formal sample size has been performed and continues inclusion into the trial will be performed during an 1,5 year period. Statistical analyses The relationship between overall survival and baseline sleep-wake rhythm will be investigated using survival statistics and/or multivariate logistic regression. Expected results The investigators expect to see a marked difference in overall survival among patients with sleep and circadian disturbances at baseline.
Sleep is a clearly necessary neurobiologic process that influences innumerable aspects of basic daily functions, physical health, and mental well-being. Recent literature shows that college students across the country are experiencing high rates of sleep deprivation. Interestingly, some recent studies have implicated this sleep loss in contributing to weight gain that occurs in the first year of college, also known as the "freshman fifteen." Rates of depression and other mental health issues, which are closely connected to sleep disturbances, are also on the rise in college campuses. The majority of the sleep data obtained in this population has been via questionnaires and self report, and the studies usually include college students at all seniority levels (e.g., freshmen, sophomores, seniors). Here, the investigators outline a novel study investigating how sleep time changes in college freshman, and how it relates to multiple different aspects of their health and functioning over the course of one quarter. As technology has advanced, the ability to easily obtain objective measurements of different health parameters has increased dramatically. The investigators plan to use wireless actigraphy devices to measure sleep over a baseline seven day period in college-bound UCSD students prior to matriculation, and for 2 additional seven day periods during the first quarter of college. To the knowledge of the investigators, this is the first study to directly measure sleep time in college freshman in their normal environment. Effects of sleep time loss will be evaluated through multiple different metrics of physical and mental health. Given the recent link between sleep disturbances and weight gain in college freshman, the investigators will plan to measure weight changes prior to entering college and at two different time points through the first quarter. The investigators will use the PSQ-9 and GAD7 batteries as measures of mental health, obtained at the same time points as the sleep and weight information. As one of the primary consequences of sleep deprivation is on neurocognition in the daytime, the investigators plan to measure vigilant attention using psychomotor vigilance testing (PVT) as well. Screen time use has recently been targeted as a possible contributor to sleep loss in adolescents as well as adults and is something the investigators will attempt to measure as well using a smartphone application. Finally, this project will test the efficacy of a one hour sleep education intervention on improving total sleep time. To the knowledge of the investigators, no other studies have closely examined how total sleep time changes during the first year of college in freshman in relationship to weight and mental health parameters, nor has PVT been done in this context. Additionally, with the increasing concerns regarding screen time use in adolescents and young adults, this study provides prime opportunity to examine this issue in the context of sleep.
This 3-arm RCT tests the effects of a sleep-enhanced adaptation (FF+) of a well-known, evidence-based transition-to-parenting coparenting intervention program (Family Foundations; FF). In one arm, families will experience FF as originally formulated; in the second, families will receive an adapted FF (FF+) program that emphasizes coparenting in infant sleep contexts; the third arm will serve as controls. It is hypothesized that (1) Compared to controls, parents in both FF groups will report improved overall coparenting and reduced overall distress, but parents in the FF+ group will show greater improvements in coparenting and individual parenting in infant sleep contexts, better infant and parent sleep, and better child adjustment; (2) early coparenting around infant sleep will be a central mechanism by which both interventions exert their effects.
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 WHISH trial applies state-of-the science behavioral principles and currently available technologies to deliver a physical activity intervention without face-to-face contact to ~25,000 older U.S. women expected to consent. It includes the National Institute of Aging (NIA) Go4Life® Exercise & Physical Activity materials 3 and WHISH developed targeted materials based on Go4Life® to provide inspirational tips and recommendations about how to achieve nationally recommended levels of PA and overcome barriers to exercise, with a means for self-monitoring and setting personal goals. The intervention builds upon evidence-based behavioral science principles and intervention components that have proven to be effective in increasing PA in older women, with innovative adaptive approaches to tailoring the delivery to meet individual (personal) needs.
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.
Formula composition is developed to resemble breast milk as close as possible, but there are still considerable differences between formula and breast milk composition, probably resulting in higher risk of overweight in childhood and higher incidence of infections in formula-fed infants. Protein levels are still higher and constituents such as alpha-lactalbumin lower in formula than in breast milk. By adding more alpha-lactalbumin to formula, rich in tryptophan, the resulting amino acid composition will allow further reduction of protein in formula. The investigators intend to include 320 infants, where 80 will be exclusively breastfed and the remainder assigned in a double blind, controlled, randomized manner to one of three formula groups; two experimental, protein reduced formula with two different levels of alpha-lactalbumin and one group given standard infant formula. The intervention period is from 4-8 weeks until 6 months of age. The infants will be followed by growth parameters, blood-, urine- and fecal biomarkers and health parameters until 5 years of age. The experimental formula will possibly result in growth, metabolism and gut microbiota as well as health parameters more similar to those of breastfed infants
The aims of this study are examine the effects of sleep deprivation in muscle recovery after a maximum eccentric resistance exercise session performed on an isokinetic dynamometer (24 series of 10 repetitions). The sample will consist of 10 men, sedentary, clinically healthy, aged between 20 and 31 years old. Two experimental groups will be developed: EXE-SLEEP, in which subjects will perform the exercise protocol (~18:00-19:00) and will be subject to normal period of sleep for 3 nights; EXE-TOTAL, in which subjects will perform the same exercise protocol and will be sleep deprived for 60 hours, followed by one night of sleep rebound.
