Filter by:Purpose The purpose of this study is to determine whether filtering out blue light at nighttime reduces post-surgical inflammation and/or moderates cognitive decline and mood and sleep alterations in patients undergoing elective CABG, AVR, MVR, CABG AVR, CABG MVR, or SAH surgery. If manipulating nighttime light in hospital rooms improves patient outcomes, then it would be a relatively easy and inexpensive innovation that could reduce post-surgical complications and save millions of dollars per year in health care costs by shortening the length of hospital stays and reducing morbidity. The investigators aim to determine the relationship between inflammation and cognitive dysfunction after cardiac surgery.
Postoperative cognitive dysfunction (POCD) is a common postoperative complication in patients aged 65 and over, which refers to cognitive function changes such as memory decline and attention deficit after anesthesia and surgery. In severe cases, personality changes and social behavior decline may also occur, resulting in irreversible cognitive impairment.Previous studies have suggested that cognitive dysfunction after general anesthesia is linked to a genetic disorder of the body clock.Exosomes are cellular forms of cellular microvesicles containing complex RNA and proteins.Exosomes can mediate the expression of genes in the late transcriptional period of the clock system, and directly or indirectly participate in the negative regulation of rhythm expression of minute control genes, playing an important role in the intercellular circadian rhythm information output pathway.Rhythm disorders in the core biological clock system of urinary exosomes and the clock control genes related to kidney can early indicate circadian rhythm changes in the core biological clock system.The sorting and detection of urinary exosome clock information materials in patients has the advantages of easy access, continuous monitoring, early diagnosis and less damage, making urinary exosome a biomarker for the diagnosis and monitoring of circadian rhythm of a good kidney biological clock system.
Emerging evidence indicates that circadian rhythms may be disrupted following cancer and its treatment, and that circadian rhythm disruption may be an underlying pathophysiological mechanism of cancer- and cancer treatment-related symptoms (CRS) such as fatigue, sleep disturbance, cognitive impairment, and depressed mood. Given the detrimental effect of CRS on cancer survivors' quality of life, and a pressing demand for effective interventions to treat CRS, there is a need for a comprehensive examination of circadian disruption related to cancer and its treatment, and its association with CRS. The study will prospectively examine circadian rhythms and a CRS composite score in recently diagnosed breast cancer patients from prior to surgery or chemotherapy to 12 months later. A matched healthy control group will serve as a comparison.
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.
The aim of the current study is to demonstrate dysregulation of immune system΄s circadian rhythms as a consequence of sepsis, as well as marked malfunction of the central circadian clock in comparison with patients without sepsis , the presence of which burdens independently the final outcome and , hence, need to be addressed.
Among the patients with Parkinson's disease, about 40%~50% will suffer from depression, 40% will suffer from anxiety, and 40%~60% will suffer from sleep disorder. These non-motor symptoms of Parkinson's disease will cause great physical and psychological pain and affect the quality of life seriously. Commonly used therapeutic drugs, such as selective serotonin reuptake inhibitor (SSRI) and clonazepam, can cause a variety of side effects, including serotonin syndrome, sexual dysfunction, daytime fatigue, insomnia, residual effects and increased risk of falls. Therefore, a new and more reasonable therapeutic choice should be sought. Agomelatine is a new type of antidepressant with novel mechanism, and can improve sleep structure and circadian rhythm. The aim of this multi-center randomized controlled trial (RCT) is to clarify the role of agomelatine in improving sleep disorders and depression in patients with Parkinson's disease
To determine if daytime bright light will promote circadian alignment and shorten or prevent delirium.
The Healthy Patterns Study intervention is a home-based activity intervention designed to improve symptoms of circadian rhythm disorders (CRD) and quality of life (QOL) in home-dwelling persons with dementia. We will use a randomized two-group parallel design of 200 people with dementia and their caregivers assigned to intervention or attention control groups.
Musculoskeletal pain has become in a major problem related to its prevalence, treatment cost, absenteeism, quality of life impairment, disability and drugs consumption. The difficulty in musculoskeletal pain control ends in the abuse of drugs by these patients, including opioids. This drugs consumption has become a health problem in the United States and around the world related to their increasing abuse mainly between 2002 and 2011 and has had an impact in the numbers of deaths caused by opioids prescription (reaching 16,651 deaths in United States in 2010). Pain is clearly associated with sleep disturbances (50-80% of these patients suffer from a sleep problem), and in turn poor sleep quality leads to increased pain sensitivity. There is evidence showing that improving sleep disturbance co-occurring pain would improve, and some may reduce the use of opioids in specific patients on long-term opioid therapy. In spite of this reciprocal relationship between sleep and pain only few programs take into account the management of sleep disorders as a non-pharmacological measure for pain control. The hypothesis is: "to address sleep and circadian disorders (SCD) using a Sleep and Circadian Intervention Program (SCIP) in patients treated with rehabilitation by chronic musculoskeletal pain (CMP) optimizes the rehabilitation outcomes and reduces opioids consumption". Main goal: The aim of this PILOT study is to evaluate the feasibility of the protocol of the present study that aims to assess the improvement in rehabilitation outcomes and decrease in opioid consumption, through the management of sleep disorders. Methodology Using a randomised (1:1) controlled feasibility study, 50 men and women will be included to evaluate methodology and identify the potential outcome of the main project. Subjects older than 18 years included in a rehabilitation program by musculoskeletal lumbar pain lasting more than three months will be recruited. Basal Visit (BV): After the signature of informed consent, a medical history, physical exam, evaluation of the pain perception (EQ5D5L), quality of life evaluation (SF36 and FOSQ), mood and anxiety (HADS y PASS20), circadian rhythm study and drugs consumption will be evaluated in both groups. Patients will be randomized to control group (usual rehabilitation program) or intervention group (usual rehabilitation program + sleep circadian intervention program-SCIP). The patient in the SCIP program will received the next intervention: 1) Educational and circadian rhythm intervention: general sleep hygiene recommendation and promotion of daily physical activity. 2) Sleep studies for sleep quality and sleep disorders diagnosis: full polysomnography 3) Sleep questionnaires for another sleep disorders. Based on the results of the studies, patients will be treated according to current guidelines for the management of sleep disorders. 6 month after the SCIP starts patients will be evaluated in the End of Study Visit (EOS) as in the BV and also in their functional improvement and health resources consumption.
