Filter by:Research on the sustainment of implemented evidence-based psychological treatments in routine practice settings, such as community mental health centers, is limited. The goal of this study is to test sustainment predictors, mechanisms, and outcomes of the Transdiagnostic Intervention for Sleep and Circadian Dysfunction (TranS-C) in community mental health centers after implementation efforts have ended. CMHC providers have been trained to deliver a "Standard" or "Adapted" version of TranS-C. Researchers will compare these two groups to evaluate differences--and possible mechanisms--with respect to sustainment outcomes.
This study will investigate the potential benefit of scheduled natural daylight exposure to improve glucose control in type 2 diabetes (T2D) patients and to unravel molecular mechanisms underlying the effects of natural daylight on circadian clocks and (glucose) metabolism in human skeletal muscle from T2D patients. Participants will stay at our research facilities and will be exposed to natural daylight or artificial light during the daytime over 4.5 days in a randomized cross-over design. For both conditions, the evening and night will be spent under standardized dim and dark conditions.
A follow-up of a cohort of participants recruited for a prior study will be conducted. In the prior study, 10-18 years olds were provided one of two treatments to improve the sleep of adolescent night-owls. The follow-up will be approximately 6-years following participation in the prior study. The goal is to establish long-term outcomes in sleep and circadian functioning, in the five health-relevant domains and in engagement in sleep health behavior.
Habits impact nearly every domain of one's physical and mental health. Evidence-based psychological treatments (EBPTs) are interventions targeting psychological processes that cause and/or maintain mental illness and that have been developed and evaluated scientifically. An implicit goal of EBPTs is to disrupt unwanted habits and develop desired habits. Yet, there has been insufficient attention given to habit formation principles, theory and measures in the development and delivery of EBTPs. In preparing to conduct a 5-year R01 on this topic, the investigators are conducting this experiment to better understand habit formation. The purpose is to distill, study and clarify key concepts in habit formation before embarking on the 5-year R01. This is necessary as there is surprisingly little research to guide key decisions, particularly for the process of dismantling unwanted habits. Hence, the aim of this experiment is to compare strategies discussed in the scientific literature, which have been minimally studied, to dismantle unwanted habits. The hypothesis tested is that each of the active strategies will be superior to the no intervention group. The study is exploratory as to which of the active strategies will be most effective.
As in healthy term babies, the ideal food for preterm infants and sick term babies is breast milk. There are many studies indicating that the composition of breast milk can vary from mother to mother, according to the gestational week of the baby and gender. In new researches on breast milk content; It is argued that breast milk is different during the day and at night, that the micro and macro nutrient content, hormones and some enzymes show different levels of secretion at different times of the day, and that breast milk has a circadian rhythm. This research is designed as a prospective, randomized, controlled type. The study will be carried out in order to evaluate the effect of Chronobiological Approach Nutrition Model application on baby's growth parameters and discharge time in preterm babies hospitalized in Neonatal Intensive Care Unit (NICU). Simple randomization method will be used for the study and the babies will be divided into intervention(n=40) and control groups(n=40). The research was carried out with 80 babies followed up in the neonatal intensive care unit. The milk of the intervention group patients will be matched circadian and given to the babies, the milk of the control group patients will be given without matching according to the clinical routine practice. Demographic data, anthropometric measurements (weight, height, head circumference of all babies will be recorded in the "Baby Monitoring Form" created by the researcher.
The aim of this project is to determine the effect of nursing care provided to intensive unit care patients according to their circadian rhythms on sleep quality, pain, anxiety and delirium.
Mental illness is often chronic, severe, and difficult to treat. Though there has been significant progress towards establishing effective and efficient interventions for psychological health problems, many individuals do not gain lasting benefits from these treatments. The Memory Support Intervention (MSI) was developed utilizing existing findings from the cognitive science literature to improve treatment outcomes. In this study, the investigators aim to conduct an open trial that includes individuals 55 years and older to assess if a simplified version of the Memory Support Intervention improves sleep and circadian functioning, reduces functional impairment, and improves patient memory for treatment.
This study was a retrospective observational cohort analysis of subjects aged 65 years and older, who underwent bilateral cataract surgery within a single (15 hospital) healthcare system, to determine the association between type (conventional or blue-light filtering) of implanted intraocular lens and survival.
The specific aims of this studyare to examine the 1) feasibility; 2) acceptability; and 3) preliminary efficacy of a tailored music intervention in home-dwelling older adults with dementia suffering from sleep disruption. Sixty dyads (older adults with dementia and their caregivers) will be randomized to receive the tailored music intervention immediately or following a four week delay.
This study evaluates the quality of sleep of patients admitted to medical and intensive care units. All of them will have a clock placed to measure their circadian activity. Also, data will be recorded through questionnaires about the unit, patient habits and medical problems.
