Filter by:The goal of this project is to determine whether the sleep and circadian rhythms of critically ill patients undergoing mechanical ventilation can be improved through practical strategies that can be employed at the bedside.
The investigators will perform a prospective, cohort study of 100 older intensive care unit (ICU) patients, to investigate the association between sleep disruption and ICU delirium.
This is a pilot research study examining two types of behavioral counseling along with the nicotine patch for smoking cessation. The study is designed to find out whether one of these counseling interventions is more effective for smoking cessation among individuals with sleep problems. The study has three parts: 1) an intake session; 2) a 10-week treatment phase, and 3) a 1-month follow-up.
The overall goal of the present application is to test the hypothesis that shift workers, who are chronically exposed to circadian misalignment and sleep loss, have a higher cardio-metabolic risk than day workers, and that the accumulated sleep debt and the degree of circadian misalignment both predict their elevated cardio-metabolic risk.
The Veterans Millennium Health Care and Benefits Act (Millennium Act) of 1999 mandated the Department of Veterans Affairs (VA) to provide non-institutional long-term care to veterans. Adult Day Health Care (ADHC) is a key component of that spectrum of long-term care services. Veterans in ADHC commonly suffer from limited poor functioning, depression, cognitive problems and low quality of life. These factors can lead to continued deterioration in functioning, loss of independence, hospitalizations, nursing home placement and death. Sleep disruption is associated with depression, low quality of life, functional decline, nursing home placement, and death among older people. Sleep disturbance is common among ADHC patients, it is not addressed within routine clinical care, and treatment may be limited to medications. Studies show that untreated insomnia and medications for insomnia can increase risk of falls and other health events among older persons. On the other hand, non-medication treatments for sleep do not show these problems. These treatments have been shown to be effective in other studies. The goal of this study is to test non-medication treatments to improve sleep among older Veterans with insomnia in a VA ADHC program. The study design will facilitate translation into routine care and application in other similar VA programs.
Sleep-wake dysregulation is a disturbance in the roughly 24-hour cycle of the circadian rhythm. Well known disorders presenting a sleep-wake dysregulation are seasonal affective disorder, jet lag and shift work. These people experience a serious mood change when the seasons change. When the day-night rhythm is desynchronized, they have sleep disturbances, little energy, and often feel depressed. An established intervention to treat this disorder is bright light therapy. Light therapy is used for affective disorders for shift workers, jet lag symptomatology and for advancing or delaying desynchronized rhythms.Two proxy measures for sleep-wake dysregulation are sleep quality and daytime sleepiness. It is known from cross sectional studies that renal transplant (RTx) recipients have a prevalence between 30% to 62% of poor sleep quality measured by self report; a prevalence of impaired daytime functioning of 34% 12 and a prevalence of depressive symptomatology of 20% to 22%. Sleep-wake dysregulation in other chronically ill population are a risk factor for morbidity and mortality. RTx nurses in the follow-up care are in the frontline for recipient's symptoms respectively problems. The psychosocial variables that should be addressed, having an association with morbidity and mortality are sleep, daytime functioning, adherence to immunosuppressive medication, exercise, smoking and depressive symptomatology. In the following research project we will address the following gaps: the fact that nature of sleep disturbances in RTx recipients has never been assessed, that there is no prevalence available on sleep-wake dysregulation and that there is no data on bright light therapy intervention in RTx recipients. Hypothesis: Renal transplant recipients having a sleep wake disregulation will have an improved sleep quality and less daytime sleepiness after 21 days of light therapy.
Fibromyalgia is a condition of chronic widespread pain, sleep disturbance and fatigue. Most of the patients with fibromyalgia complain of either non-restorative sleep or complaints of disturbed sleep due to pain. The study aimed at examining the effects of milnacipran on sleep disturbance in patients with fibromyalgia. The study is a randomized, double-blind, placebo controlled, two way crossover polysomnography (PSG) study to explore the effects of milnacipran on sleep disturbance. Patients received either milnacipran 50 mg twice a day (BID) or matching placebo.
Endothelial dysfunction, or abnormal functioning of the lining of blood vessels, appears to be a key process in the development of cardiovascular disease. Endothelial dysfunction appears to be caused by both sleep disordered breathing and obesity. As endothelial dysfunction is among the first clinical marker that predicts future cardiovascular events, understanding molecular mechanisms leading to impairment of endothelial function is very important. Endothelial function requires the proper functioning of endothelial nitric oxide synthase (eNOS). eNOS activity is tightly regulated by caveolin-1, a protein important in the formation of cellular structures called caveolae. Low levels of caveolin-1 facilitate optimal nitric oxide synthesis in endothelial cells as caveolin-1 helps to spatially organize eNOS in close proximity to signaling proteins that are important for eNOS activation. In certain diseases however, the balance of caveolin-1 and eNOS can be disrupted resulting in impaired nitric oxide synthesis and leading to endothelial dysfunction. The investigators therefore seek to characterize levels of caveolin-1, and correlate this with the presence or absence of sleep disordered breathing, obesity, and cardiovascular disease. The current IRB protocol covers the performance of fat biopsies on subjects who have recently completed a sleep study either in the Center for Sleep Medicine or in our sleep laboratory and were found to have sleep disordered breathing or no sleep disordered breathing, subject with sleep disordered breathing who have been treated successfully with continuous positive airway pressure for 3-6 months, and subjects undergoing other studies in our lab who are obese or non-obese and subjects who have known cardiovascular disease and subjects without known cardiovascular disease.
The purpose of this study is to find out what effects Exposure, Rescripting, and Relaxation Therapy (ERRT) has on nightmares and associated problems in veterans.
The goal of this research study is to learn if a type of light therapy can be used to help patients with advanced cancer who are having difficulty sleeping to sleep better.
