Filter by:The purpose of this study is to determine whether advancing the timing of home parenteral nutrition from overnight to daytime regimens leads to improved glucose profiles and sleep quality, and other changes in plasma metabolic signatures.
The purpose of this study is to determine whether modifying the timing of nutrition support from overnight to daytime enhances sleep quality, preserves circadian rhythms, and improves overall inflammation and cardiometabolic profiles in postoperative patients in the cardiac surgical ICU on enteral nutrition.
MB-College (MBC) is an 9-week, 9 session program (i.e., the study intervention being tested in the RCT) providing systematic and intensive training in mindfulness meditation practices, applied to health behaviors relevant to college students and young adults. The MBC intervention will be administered live, online via the free video conferencing platform, Zoom, to all eligible study participants enrolled in the active arms of the study. In addition to the 9-week, 9 session MBC class, referred to as "standard dose MBC" from here on out, investigators will also be testing a "low-dose MBC" version of the intervention, where each weekly session will run 1.5 hours in length rather than 2.5 hours. This is a 3-arm randomized controlled trial. The standard-dose and low-dose versions of the MBC intervention will be compared to a third arm of the study, a health education active control group. Members of the control group will be offered the MBC class upon completion of the research study. The Study Aims are to: (1) Evaluate feasibility and acceptability of MBC delivered in two online formats (standard dose vs. low dose). (2) Evaluate impacts of MBC standard-dose vs. MBC low-dose vs. health education control group on health conditions relevant for emerging adults, demonstrated to be influenced by MBC in a prior study, specifically depressive symptoms, loneliness, and sedentary activity. (3) Explore mechanisms by which MBC may exert effects on aforementioned health conditions, including interoceptive awareness, decentering, and perceived stress. Participant Population: young adults aged 18-29 years of age, residing in the United States who screen eligible will be invited to enroll. Students will be screened using a two-part process taking place online. Research assessments at baseline and 3-month will take place digitally using Qualtrics, LLC (Provo, UT, USA) survey management tool. Participants will be sent secure links via email that can be accessed with their participant identification number. Enrolled participants will be randomly assigned to one of three groups: (1) standard MBC; (2) low-dose MBC or (3) health education control group. The control group will be given the opportunity to participate in the intervention after the study MBC course is completed and follow-up assessments have been administered.
This proposed project will investigate whether a variable or a stable sleep schedule will be more effective in minimizing neurobehavioural and metabolic deficits when total sleep opportunity across two weeks is below the recommended sleep duration. In this laboratory-based, stay-in study, 60 young adults will be randomized into 1 of 3 groups. After 2 nights of 8-h time-in-bed (TIB) that simulate longer sleep opportunities typical of weekends, the stable short sleep group will have a 6-h TIB in each of the following 5 'weeknights' (8866666). The variable short sleep group (8884846) will also have a total TIB of 30h during the 'weeknights', although TIB varies across the 'weeknights'. The nightly TIB of the well-rested control group will be 8h (8888888). These manipulations will repeat in the second week, enabling the tracking of outcome measures during recurrent weeks of sleep restriction on 'weekdays' and extension on 'weekends'. A test battery assessing basic cognitive functions and mood will be administered 5 times a day. A long-term memory encoding task will be administered after week 1. A functional Magnetic Resonance Imaging (fMRI) brain scan, and an Oral Glucose Tolerance Test (OGTT) will be conducted after the second 'weekend' night and after the last 'weeknight' each week. Continuous glucose monitoring will be conducted throughout the experiment. Sleep will be measured every night with polysomnography.
This study tests the effectiveness of a new educational intervention designed to improve sleep outcomes among an older adult population.
The investigators propose to use a parallel group, randomized controlled trial to test the efficacy of a 13-week personalized approach to reducing smoking intervention versus a second approach using a different health intervention on smoking cessation, healthy sleep metrics, and biomarkers of cardiovascular risk in a sample of 200 treatment-seeking smokers who are adults living with HIV (ALHIV). To enroll in the study, treatment-seeking ALHIV smokers will undergo phone and in-person study eligibility assessments, including a history, physical examination, screening laboratory tests, and an overnight in-home objective sleep assessment. Eligible subjects (N=200) will be randomized to the 13-week Approach 1 (N=100) or Approach 2 (N=100) condition. All subjects will receive a 12-week course of varenicline (beginning in week 2) and 8 individual 15-minute smoking cessation counseling sessions [weeks 1, 2, 3 (target quit date), 5, 7, 9, 11, 13]. At each in-person counseling session, 30-45 minutes of Approach 1 or Approach 2 counseling will be provided as well. While receiving varenicline, the study team will monitor for side effects and changes to blood pressure at each study visit for safety reasons. Study measures are collected at all time points including EOT (week 13), and 6-month follow-up (6MFU).
Up to 72% of adolescents with ADHD portray sleep problems. The most common sleep difficulties in adolescents with ADHD are initial insomnia, nocturnal awakenings, non-restorative or restless sleep. These difficulties seem to be causally related to increased ADHD symptom impairment, oppositional and depressive symptomatology, and functional impairments in daily life, resulting in a vicious circle of sleep problems and impairment. Thus, reducing sleep problems is an important intervention target. However, to date there is no evidence-based cognitive behavioral sleep treatment available. Sleep-focused treatments need adaptation towards this developmental phase/disorder for effectiveness, as ADHD and sleep problems are bi-directional. Therefore, a blended treatment targeting the core deficits integrating motivational interviewing, planning skills and sleep interventions is needed. Thus, the aim of this project is testing the short and 3 months follow-up effectiveness of the blended CBT sleep intervention in adolescents with ADHD.
The study will be done among undergraduate students in Sohag University for assessment of quality of sleep and its determinants .It will be done in practical faculties and theoretical faculties .
The goal of the present study is to optimize effects of slow oscillatory transcranial direct current stimulation (so-tDCS) on sleep physiology and memory consolidation in humans by combining computational and experimental human models in an iterative process. The investigator therefore works in cooperation with Prof. Dr. Klaus Obermayer (TU Berlin), who contributes computation models with the aim to mechanistically understand the impact of different perturbations on sleep-related electrophysiological features, and to subsequently optimize so-tDCS parameters for inducing SO and spindle activity.
Restless leg syndrome (RLS) is a very common neurological condition characterized by an uncontrollable desire to move the legs. Due to the traumatic effect of RLS on morbidity, the patient is negatively affected in many different directions. The duration and quality of sleep of the patients decrease, and their cognitive functions change. The prevalence or risk of anxiety and depression increases in this population. At the same time, the quality of life of patients is significantly reduced. Among the different pharmacological agents used in RLS, dopamine agonists are the most widely used. However, the reporting of serious and common side effects related to this treatment has led to non-pharmacological approaches in the treatment of RLS and the effectiveness of many different approaches has been investigated. The exercise approach, which is determined to be effective in the treatment of the disease, is a subject that has been little studied. The type, duration and frequency of optimal exercise could not be standardized. In addition, the effect of exercise on RLS patients has been investigated in limited subjects. For this reason, the aim of our study is to examine the effect of different exercise programs on symptoms, sleep, cognitive functions, quality of life, psychological status and fatigue in patients with RLS.
