Filter by:We aim to observe the unwanted effects of nightshift work and short term insomnia on erectile function of men aged between 25 to 60 years. We will also compare the levels of serum testosterone in the target group and compare it with the ones who don't work in hightshifts.
Pain is one of the most common causes of healthcare contact and long-term sick leave, with negative consequences on physical and mental health. Poor sleep is common in chronic pain patients. Epidemiological studies indicate that 5-7% of patients with chronic pain are treated regularly with strong opioids. Negative side effects of pain modulating drugs on sleep quality have been reported, which may have negative influence on overall disease management in chronic pain patients. However, to date there are conflicting results regarding the effects of opioids on sleep, since the pain relieving effect of opioids seem to affect sleep positively. There is data suggesting that physical activity has positive effects on both pain perception and sleep quality (and duration). The aim of the study is to explore insomnia and characteristics of sleep in patients with chronic pain and the relationship with physical activity level and opioid use.
Post-Traumatic Stress Disorder (PTSD) is a public health problem due to both its chronic nature and the low response rate to conventional therapies. Sleep disorders are the first cause of complaint in patients with PTSD due to night awakenings, difficulty to fall asleep and nightmares. According to a part of the scientific community, replicative traumatic nightmares represent PTSD's basis mechanism. Traumatic nightmares generate disabling symptoms such as anxiety reactions, while maintaining the symptoms by depriving the individual of good quality sleep. Traumatic nightmares may thus be a sign of PTSD seriousness and chronicity, although their physiological basis remain poorly known. In the military population, which is highly exposed to psychological traumatism, PTSD prevalence is very high and is associated with severe intensity patterns, a very high frequency of replicative nightmares and a low response to conventional therapies.
This observational study will test and evaluate the RestEaze ambulatory sleep monitor for the detection and classification of leg movements during sleep (LMS) and other sleep measures.
Severe fatigue, depression, sleep problems and cognitive impairment are the most commonly reported side effects of cancer treatment. These aversive side effects are hypothesized to be related to the disruption of circadian rhythms associated with cancer and its treatment. Exposure to Bright White Light (BWL) has been found to synchronize the circadian activity rhythms but research with cancer patients has been scarce. Therefore, the proposed randomized control trial (RCT) will test if systematic light exposure (sLE) will minimize overall levels of cancer-related fatigue (CRF), depression, sleep problems and cognitive impairment among breast cancer patients undergoing breast cancer treatment (i.e., surgery, chemotherapy). SLE incorporates the delivery of harmless UV-protected BWL or Dim White Light (DWL - standard comparison in light studies) delivered to patients by using special glasses for 30 minutes each morning, during their treatment. The proposed study, including a delineated comparison condition, will investigate the effects of BWL on CRF, sleep, depression, cognition, circadian rhythms, and inflammation markers among patients undergoing breast cancer treatment. The proposed RCT could have major public health relevance as it will determine if an easy-to-deliver, inexpensive, and low patient burden intervention reduces common side effects (e.g., CRF, depression, cognitive impairment) of cancer treatment (i.e., surgery, chemotherapy). Aim 1 - Assess whether Bright White Light (BWL) compared with Dim White Light (DWL) among breast cancer patients undergoing breast cancer treatment will minimize overall levels of CRF, depression, sleep problems, and cognitive impairment during and after breast cancer treatment, compared to healthy controls. Aim 2 - Determine whether the BWL intervention affects cortisol rhythms, circadian activity rhythms, melatonin rhythms, and inflammation markers that have been identified as correlates/causes of cancer-related side effects (e.g., CRF, depression, sleep problems). Aim 3 - Exploratory: Explore whether the effects of BWL compared to DWL on the cancer-related side effects (e.g., CRF, cognitive impairment) are mediated by the beneficial effects of the BWL in synchronizing circadian rhythms. Aim 4 - Exploratory: Explore potential moderators of the intervention including seasonality, chronobiology, personality, and social factors.
The main goal is to study the effects of internet-delivered cognitive behavioural therapy with minimum guidance for comorbid sleep problems in alcohol use disorder, in routine addiction care.
This is a novel observational study with the overarching aim of evaluating the association between poor sleep health and poor quality of recovery in a surgical setting. It hopes to assess and optimize the perioperative sleep health of patients so significant improvements in their quality of recovery and health outcomes may be achieved.
The goal of MEM-ASA is to investigate the prevalence of anxiety/depression, sleep disturbances and alcohol use disorder in elderly with cognitive complaints. In memory clinics of Normandy (France), all patients aged over 50 year-old are systematically questioned about anxiety, depression, sleep quality and alcohol use disorder. They also perform a neuropsychological assessment. Questionnaires are given to the patient and his/her caregiver to be filled in at home. Levels of anxiety/depression, sleep quality and alcohol consumption are related to neuropsychological performance, diagnosis and responses to the questionaires.
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.
Treatment with melatonin is often initiated on an insufficient basis as it has not been established prior to starting the treatment whether or not the child had delayed release of endogenous melatonin. At the clinic, it has furthermore been observed that the length of time a child experiences an effect of melatonin treatment varies substantially. In a clinical context, treatment with melatonin is used increasingly (www.Medstat.dk). However, there is no tradition in Denmark for measuring the endogenous melatonin level before initiating such treatment. Hence there is no way of knowing to what extent the sleep problems were indeed caused by delayed melatonin release. There seem to be no studies on the difference in the effect of melatonin treatment of children and adolescents depending on whether or not they have delayed DLMO. Likewise, there are no studies including adolescents. As can be seen, it is important to gain more knowledge about the normal release of melatonin, and the release of melatonin in a group of children and adolescents with a variety of psychiatric diagnoses. It is also essential to investigate whether there are any differences in the release of melatonin in children and adolescents with chronic sleep onset problem and children and adolescents who do not have sleep problems.
