Filter by:Most ICU patients experience sleep and circadian disruption (SCD), which causes a profound negative impact on patients, such as prolonged mechanical ventilation, glucose intolerance, and the occurrence of delirium. In order to better promote the alignment of circadian rhythm in ICU patients, this project will explore the prevalence of SCD and a series of influencing factors contributing to SCD in ICU patients, to help construct targeted intervention programs in the future.
Circadian rest-activity rhythm disorders are common in patients with cancer, particularly in advanced disease. A recent international e-Delphi study has outlined recommendations for the assessment and reporting of the disorder and subsequently an observation study is underway assessing a cohort of patients with advanced cancer. Affected patients are eligible to enter a feasibility study assessing a non-pharmacological multi-modal intervention.
The aim of this randomized controlled trial (RCT) is to clarify the effect of bright light therapy on motor symptoms and sleep disorders in patients with Parkinson's disease.
Circadian rhythms plays an important role for healthy. And critical illness contributes to the disruption of circadian rhythms. Not only right but also feeding can affect the circadian clock gene expression. In a investigators' previous study, some metabolic indicators (the albumin level, total cholesterol level and total bile acid level) and the increases in lymphocyte counts in the sequential feeding group were different from those in the continuous feeding group. Investigators think sequential feeding may adjust circadian clock gene expression for its effect on metabolism and immunity. Moreover, sequential feeding did alter the abundances of some gut microbes to some degree in the investigators' previous study. Investigators think sequential feeding may adjust gut flora rhythms.
Circadian rest-Activity Rhythm disorders (CARDs) are common in patients with cancer, particularly in advanced disease. CARDs are associated with increased symptoms, poorer quality of life, poorer response to anticancer treatments and shorter survival. The goal of this observational study is to see how common CARDs are in patients with advanced cancer and to characterise their rest and activity patterns in more detail. A recent study has outlined a standard way to assess and diagnose a CARD. This study aims to assess patients with advanced cancer for a CARD using a novel screening tool against this newly formed diagnostic criteria. Potentially modifiable risk factors will be considered along with associations between CARDs and symptoms, sleep preferences, sleep quality, daytime sleepiness, quality of life measures and predictors of survival.
Introduction 16.8% of the Danish adult population are obese (Body Mass Index> 30 kg / m2). Obesity increases the risk of lifestyle diseases such as type-2 diabetes and non-alcoholic fatty liver. People with mental illness have an increased risk of developing obesity. Both obesity and certain mental disorders (bipolar disorder and schizophrenia) are associated with circadian rhythm disorders. Clinically, this may manifest as reduced sleep quality, depressive symptoms and increased fatigue, but also deregulation of a wide range of bodily processes subject to the circadian rhythm. In circadian rhythm disorders, the pattern of how mRNA of specific 'clock genes' is expressed in the cell may be affected. These clock genes are associated with obesity, bipolar disorder and schizophrenia. Despite the clear indications of an interplay between mental illness, obesity and circadian rhythm disorders, the relationship between these illnesses are largely unexplored. Aim The aim of this study is to investigate circadian disturbances in people with and without obesity, as well as people with obesity and a comorbid diagnosis of either schizophrenia or bipolar disorder. Methods The study population will consist of: 1. People with obesity and schizophrenia (N=22) 2. People with obesity and bipolar disorder (N=22) 3. People with obesity without psychiatric disease (N=22) 4. People with BMI 18.5 - 25kg/m2 and no psychiatric disease (N=20) Study Procedure Participants will visit the clinic 2 times. At each visit participants fill in questionnaires and perform physical tests. Between visit 1 and 2, participants will over a 2-day period (at-home), collect biological samples (Four hair- and six saliva samples per day). In addition, participants will wear accelerometers and continuous glucose monitors (CGMs) for a total of 8 days, including the 2-day sampling period. Sampled hair follicles are analyzed for relative expression of clock gene mRNA. Saliva is analyzed for cortisol- and melatonin content. The four participants groups are analyzed and compared on daytime variation in mRNA expression, cortisol- and melatonin concentration, and body temperature. Perspectives A comparison of patient groups presenting with mental disease, obesity and circadian disturbances may provide new insight into the association between these diseases.
The Self-care for Dementia Caregivers Study is a behavioral health intervention that uses digital monitoring tools and motivational health coaching to help caregivers of persons with dementia engage in a regular routine of self-care. Participants wear an apple watch for the objective collection of sleep-wake rhythms. They receive personalized feedback on their sleep-wake rhythms via a new app. Health coaches call participants weekly, for 6 weeks to help participants meet their health/sleep goals and promote self-knowledge of regular routines. Participants will help the study team improve the design elements and content of the mobile app. The goal of this intervention is to reduce psychological distress and caregiver burden.
Sleep is regulated by the interaction of homeostatic and circadian processes. The homeostatic process determines sleep propensity in relation to sleep-wake history, the circadian one is responsible for the alternation of high/low sleep propensity in relation to dark/light cues, and is substantially independent of preceding sleep-wake behaviour. The circadian timing system encompasses a master clock in the brain and peripheral, ancillary time-keepers in virtually every organ of the body. In recent years, evidence has emerged that circadian disruption has serious medical consequences, including sleep loss, increased cardiovascular morbidity and increased risk of certain types of cancer. Evidence is also emerging that hospitalization per se weakens circadian rhythmicity, due to disease itself and to modified light, food and activity cues. The aim of our project is to test an inpatient management system (CircadianCare) that limits the circadian impact of hospitalisation by enhancing circadian rhythmicity through an assessment of the patient's specific circadian features/needs and an ad hoc, personalized light-dark, meal and activity schedule to cover the whole of the inpatient stay. This will be compared to standard inpatient management in terms of patients' perception, sleep-wake quality and timing during hospitalisation, inpatient utilization of sleep-inducing medication, length of hospitalisation, and prognosis (i.e. outcome of hospitalisation, subsequent hospitalisations and post-discharge sleep-wake disturbances). The CircadianCare system is expected to benefit prognosis, decrease costs, and change the way hospitals are organized and designed in future, with potential direct relevance to the plans for the new University Hospital of Padova.
The Multidisciplinary Expert System for the Assessment & Management of Complex Brain Disorders (MES-CoBraD) is an interdisciplinary project combining Real-World Data (RWD) from multiple clinical and consumer sources through comprehensive, cost-efficient, and fast protocols towards improving diagnostic accuracy and therapeutic outcomes in people with Complex Brain Disorders (CoBraD), as reflected in Neurocognitive (Dementia), Sleep, and Seizure (Epilepsy) disorders and their interdependence. It brings together internationally recognized experts in medicine, engineering, computer science, social health science, law, and marketing and communication from across Europe, and combines clinical information and scientific research in CoBraD with technical innovation in secure data-sharing platforms, artificial intelligence algorithms, and expert systems of precision and personalized care, with a primary focus on improving the quality of life of patients, their caregivers, and the society at large. It leverages RWD from diverse CoBraD populations across cultural, socioeconomic, educational, and health system backgrounds, with special attention on including vulnerable populations and minorities in an equitable manner and engaging key stakeholders to maximize project impact.
The precise role of the intrinsic circadian regulatory mechanism behind the pathogenesis of enuresis is not fully understood, but in theory, circadian rhythm irregularity may be the primary pathogenic mechanism not only for urinary outflow mechanisms but also for nocturnal bladder function. The proximity between SCN centers that control AVP release, sleep/arousal, voiding, and baroreregulation may provide the basis for circadian rhythm disturbance in one or more of these biological functions. Ganglion cells containing melanopsin pigment in the retina transmit the information they receive from the outside world about the light-dark state to the SCN via the retinohypothalamic pathway. Peripapillary retinal nerve fiber layer (RNFL) thickness, optic nerve head and macula are examined most frequently for the diagnosis of glaucoma and the detection of progression with optical coherence tomography (OCT). If differences in ganglion cell thickness can be detected using OCT in these children, a new avenue in Enuresis Nocturna may be opened.
