Filter by:The intensive care unit (ICU) is recognizably detrimental to sleep and circadian health, and critical survivors frequently report the presence of alterations in this regard after hospital discharge. However, an appropriate evaluation of sleep and circadian rhythms is often neglected given the high associated cost and/or the need of collaboration of the patients. In this project, the investigators propose alternatives to ultimately improve the management of sleep and circadian health after critical illness. The researchers will evaluate the role of microRNA (miRNAs) expression profile in identifying the compromised sleep and circadian health of critical patients during the ICU stay, in the short (3 months after hospital discharge), and in the long-term (12 months after hospital discharge). Also, models based on machine learning techniques will be developed to predict adverse outcomes in this regard after hospital discharge.
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 50 years and older to assess if a novel version of the Memory Support Intervention improves sleep and circadian functioning, reduces functional impairment, and improves patient memory for treatment.
The train-the-trainer (TTT) approach is a promising method of sustaining training efforts in community mental health centers (CMHCs). This study will test the implementation and effectiveness outcomes of a sleep treatment delivered by CMHC providers who are trained and supervised within CMHCs via TTT. The investigators will test two versions of the sleep treatment, a "Standard" version and an "Adapted" version that has been adapted using theory, data and stakeholder inputs to improve the fit for SMI patients treated in community mental health centers.
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.
The study will test a sleep-health intervention that leverages the science on habit formation. It will evaluate if adding a text messaging intervention improves habit formation. The participants will be 18-30 years old.
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.
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.
Perinatal depression and anxiety are common, serious, and frequently overlapping disorders that increase morbidity and mortality in new mothers (including suicide) and result in poor infant/child outcomes. Current therapies often fail to produce recovery or are poorly tolerated, and many pregnant women seek non-pharmacologic therapy or forgo treatment when non-pharmacologic options are not available. Expectant and new mothers who experience circadian rhythm dysregulation are at increased risk for perinatal depression. This Confirmatory Efficacy Clinical Trial of Non-Pharmacological Interventions for Mental Disorders R01 seeks to test whether a Personalized Integrated Chronotherapy (PIC) intervention can improve treatment outcomes for pregnant patients seeking outpatient treatment for depression, with or without anxiety. PIC is a multicomponent treatment consisting of bright light therapy, sleep phase advance, and sleep stabilization/restriction that targets the Research Domain Criteria (RDoC) constructs of circadian rhythms and sleep-wake behavior. To increase sample size and diversity and accelerate recruitment, this study will be performed at 4 sites that differ in clinical structure and that have piloted the PIC intervention. The study will enroll expectant mothers diagnosed with major depressive disorder during 3rd trimester of pregnancy. Participants will be randomized to either: (a) usual care (UC, n = 110) or (b) PIC+UC (n = 110). PIC+UC will have pregnancy and postpartum components and will be administered via a personalized approach tailored to optimize the intervention based on each patient's individual circadian and sleep timing. After a baseline assessment, PIC will be prescribed during 5 dedicated clinical visits: three during 3rd trimester of pregnancy and 2 in the postpartum period. UC will consist of medication and/or psychotherapy. UC will be quantified in both groups to evaluate differences between the PIC+UC and UC groups. Mood will be measured in both groups by blinded clinician interview and patient self-report. The safety profile of the PIC intervention will be assessed by evaluation of side effects/adverse events. Importantly, the study will also examine the target mechanisms by which PIC is hypothesized to work and test the mediation effects of the circadian targets on improvement in mood symptoms. Participants will wear wrist actigraphy/light monitors continuously during weeks 28-40 of pregnancy and postpartum weeks 2-6 to assess light exposure and to estimate sleep timing and duration. Circadian phase (measured with salivary dim light melatonin onset) will be measured at baseline during pregnancy (~30 weeks' gestation), at 36 weeks' gestation, and at postpartum week 6. Exploratory aims will examine associations between infant sleep behavior and maternal circadian rhythms and factors relevant to future dissemination of PIC. If this intervention is effective, perinatal PIC could change clinical practice and have major public health impact due to the high prevalence of perinatal depression and anxiety, the negative effects of mood disorders on mothers and their children, and the need to provide effective, novel, non-pharmacologic therapies for women with perinatal mood disorders.
The sleep disturbance commonly experienced by individuals with a severe mental illness (SMI) reduces these individuals' capacity to function and contributes to key symptoms. This study will test the effects of a sleep treatment that has been adapted using theory, data and stakeholder inputs to improve the fit for SMI patients treated in community mental health centers (CMHCs), relative to the standard treatment. The investigators will also determine if the adapted and standard versions can improve sleep, improve functioning and reduce symptoms.
