Filter by:The purpose of this study is to investigate whether the effects of biofeedback-based music programs using a smart device application can improve perioperative sleep quality in patients undergoing breast cancer surgery.
Dexmedetomidine and ketamine are both suggested for sedation and analgesia in ICU patients with mechanical ventilation. Recent studies suggest that low-dose dexmedetomidine or ketamine/esketamine may improve sleep quality of ICU patients. The purpose of this trial is to observe whether night-time infusion of low-dose dexmedetomidine-esketamine combination can improve sleep structure of patients with mechanical ventilation in the ICU.
Post-stroke sleep disorder and motor/cognitive dysfunction are common complications that affect the quality of life of older patients. The proposed study investigates the effects of an acupuncture-like method applied to six bilateral acupoints on sleep quality, motor function and cognition in older adults with chronic stroke. The study will be a single-blind (i.e., only patients will be blinded about the research purpose) randomized controlled trial (i.e., patients receiving the treatment is chosen at random) with a pre-mid-post follow-up design and involve two parallel groups of post-stroke survivors (aged > 55 years) diagnosed with insomnia. Participants will be randomly allocated in a 1:1 radio to two independent groups, i.e., a treatment group or placebo group, namely a transcutaneous electrical nerve stimulation placed on acupoints (Acu-TENS) or a placebo group. The Acu-TENS group will receive a 6-week treatment that includes a 30-minute Acu-TENS + sleep hygiene program (SHP) twice a week. The placebo group will receive sham Acu-TENS (i.e., devices with the electrical circuit disconnected) + SHP with the same frequency as the Acu-TENS group. The selected acupoints will be bilateral Hegu (LI4), Quchi (LI11), Neiguan (PC6), Shenmen (HT7) on the arm and Sanyinjiao (SP6) and Zusanli (ST36) on the lower limb. The study's primary outcomes will be sleep quality measured by the device of ActiGraph and the self-report survey. The secondary outcomes will be motor function, measured by physical performance tests, cognition, measured by computer battery, and quality of life, measured by the self-report survey. All outcomes will be measured at the baseline assessment (before the treatment), mid-term assessment (after the three weeks treatment), post-treatment assessment (after the six-week treatment), and follow-up assessment (two weeks after the treatment ended). It is hypothesized that the Acu-TENS + SHP treatment will better alleviate insomnia, improve cognition and motor function in participants than the sham Acu-TENS + SHP treatment.
The scope of the study covers the effects of music therapy on risk perception levels and sleep quality in pregnant women hospitalized due to the diagnosis of premature birth threat.
Background: The patients who are admitted to ICUs mostly experience sleep disturbance. Seeking an effective strategy and integrating it into the daily routine is of clinical importance. Therefore, we aim to examine the effects of guided virtual reality integrated into the multicomponent program (SLEEP care) on sleep quality and quantity in critically ill patients. This will be a randomized controlled trial with assessor-blinded and two-arm parallel-group design. A total of 120 critical ill adults will be randomly allocated to the SLEEP care group and eyemask groups in a 1:1 ratio (60 participants in each group).
Poor sleep quality and short sleep duration may be a mechanistic component of cognitive impairment in older adults, associated with a decline in brain-derived neurotrophic factor. Increasing the availability of nicotinamide adenine dinucleotide (NAD+) with supplementation of its precursor, nicotinamide riboside (NR), a form of vitamin B3 may increase the expression of brain-derived neurotrophic factor. This study proposes to examine the benefits of NR supplementation on sleep and cognitive function in older adults with comprehensive subjective and objective measures and to explore its impacts on serum brain-derived neurotrophic factor.
The objective of this study in healthy volunteers is to evaluate whether the composition of the gut microbiota and sleep quality influence the susceptibility to develop peripheral and central sensitization of pain pathways. In two different experimental sessions, the following factors will be tested: the influence of the composition of the gut microbiota on the susceptibility to develop peripheral sensitization of nociceptors, and the susceptibility to develop central sensitization of pain pathways. To assess susceptibility to peripheral sensitization, a solution of capsaicin (the active component of chili pepper) will be applied to the skin to induce neurogenic inflammation produced by the release of substances from nociceptors at the peripheral level. This neurogenic inflammation is characterized by a transient redness of the skin that will be measured with an infrared camera. To evaluate the susceptibility to sensitization at the central level, a high frequency electrical stimulation will be applied to the skin. This stimulation induces an increase in sensitivity to mechanical stimulation secondary to central sensitization. The intensity, extent and duration of this mechanical hyperalgesia will therefore be used as a measure of susceptibility to central sensitization. A stool sample and a blood sample will be taken. These samples will be used to characterize the composition of the intestinal microbiota, as well as the metabolites produced by this microbiota. These analyses will allow a comparison of the composition of the microbiota and the metabolites in subjects with a tendency to develop low vs. high sensitization at the peripheral and central levels. Similarly, sleep quality and average sleep duration will be assessed using questionnaires and a measurement of the participant's activity using a wrist movement sensitive bracelet. This information will be used to assess whether some of the interindividual variability in developing peripheral or central sensitization might be related to differences in sleep quality. Finally, systemic inflammation could be a factor modulated by sleep and gut microbiota, influencing pain perception and susceptibility to sensitization. For this reason, systemic pro- and anti-inflammatory cytokines will be measured in the blood sample.
This study aims to investigate the effects of cardiac rehabilitation on sleep quality and sleep duration in patients after coronary artery bypass graft.
The study aims to investigate the status of circadian rhythm and sleep quality in ICU patients and their influence factors. And explore the pathway of circadian rhythm on ICU delirium. The hypothesis of study is that icu patients experience circadian and sleep rhythm disorder, especially in patient who have delirium.
Introduction: Sleep disorders are a growing concern for public health, being related, among others, to an increased risk of cardiovascular diseases or poorer cognitive functioning. In addition, these might have a possible impact on aspects related to personal motivation and quality of life. However, few studies have analyzed the possible determinants of sleep quality in the adult population as a whole, establishing patterns based on these. Objective: To evaluate the determinants of sleep quality in a representative sample of the general adult population aged 25 to 65 years old and to establish patterns of sleep quality based on lifestyles, psychological factors, morbidities and biological markers. Methodology: Design: This is a descriptive observational, cross-sectional study that will include a representative sample of 500 people aged 25 to 65 years old from the city of Salamanca (Spain) selected by random sampling stratified by age and sex. Study variables: A visit lasting approximately 90 minutes will be carried out. The determinants of sleep quality will be assessed using both objective and self-reported methods. Variables related to life styles will be assessed: physical activity, diet and toxic habits including tobacco smoking or alcohol use. Morbidity data will also be collected, and psychological factors such as anxiety will also be assessed. Serum melatonin levels will be determined as a biological marker related to sleep quality.
