Filter by:The purpose of this study is to assess the safety and efficacy of Traditional Chinese medicine (TCM) according to Yin Yang theory for treatment of chronic insomnia .
Surveys indicate that 85% of the adult population consume caffeine on a daily basis. Caffeine acts on sleep homeostatic mechanisms by antagonizing the sleep factor adenosine. Whether and how caffeine also impacts on the circadian regulation of sleep and -wakefulness is fairly unexplored. This study quantifies the influence of regular caffeine intake and its cessation on circadian promotion of sleep and wakefulness, on circadian hormonal markers, well-being, neurobehavioral performance and associated cerebral mechanisms. The knowledge is expected to contribute important insights on recent societal changes in sleep-wake behavior (e.g., shorter sleep duration and delayed sleep phase) and the related increase in people suffering from sleep problems.
The aim of this project is to determine the effect of nursing care provided to intensive unit care patients according to their circadian rhythms on sleep quality, pain, anxiety and delirium.
Insomnia and sleep disorders are prominent health problems in modern society. High working pressure, fast pace of life, the use of electronic products and other reasons lead to the high incidence of insomnia and sleep disorders, which affect people's physical and mental health seriously, long-term insomnia will increase the risk of various health problems, and may even lead to malignant accidents. There are few effective methods to treat insomnia or sleep disorders, only part of the problem can be solved by sleeping pills and psychotherapy. However, drug therapy has side effects such as drowsiness on the next day, ataxia, anterograde amnesia and so on, and long-term application is addictive. Traditional Chinese medicine (TCM) has certain characteristics and advantages in the treatment of insomnia, but there is lack of evidence in clinical research that meets the requirements of modern evidence-based medicine, to prove the exact efficacy and safety of TCM in the treatment of insomnia. In addition, the research shows that the internal biological clock cycle of normal human body is 24-hour, insomnia may be related to biological clock gene. In this study, the outpatients with insomnia were taken as the research object. To observe the efficacy and safety of TCM in the treatment of insomnia by recording the participants' baseline demographic data, questionnaire survey, and conducting hematology examination. At the same time, to know the TCM constitution type of insomnia patients, through questionnaire survey with "Classification and Determination of TCM constitution table" that published by China Association of Chinese Medicine.And to explore the correlation between insomnia and circadian rhythm of biological clock .
This study will investigate the effectiveness of light and sound modification in improving sleep qualit , and circadian rhythms in MICU patients with Mechanical Ventilation in Taiwan. Hypothesis: 1. The sleep quality in intervention group is significant improving than usual-care group at Day 1 (after the first intervention), Day 2 (after the second intervention), and Day 3 (after the third intervention). 2. The circadian rhythm in intervention group is significant improving than usual-care group at Day 1 (after the first intervention), Day 2 (after the second intervention), Day 3 (after the third intervention).
This study seeks to examine central and peripheral circadian mechanisms in Blacks with appropriately dipping systolic blood pressure (blood pressure that dips by at least 10%) compared with non-dipping systolic blood pressure (blood pressure that dips by less than 10%) using a constant routine protocol. Constant routine protocols are commonly used in the field of circadian biology to examine rhythms in biological processes while controlling the entraining effects of light, activity, and diet.
This study evaluates the feasibility, acceptability, and efficacy of an online education course about circadian rhythms and health. Half of participants will be enrolled into the online course and the other half will receive materials on sleep hygiene as a control.
This project aims to test the impact of melatonin and MTNR1B variation on regulation glucose regulation in a highly controlled in-laboratory setting and ex vivo in pancreatic islets.
The current study, aims through a robust design to provide a simple answer on whether progesterone levels of the same individual may significantly vary depending on the time of blood retrieval before the ovulation triggering, by evaluating the daily variability of serum progesterone on the day of triggering in healthy women who perform a COS for oocyte donation, through multiple blood samplings.
Both light and exercise are effective countermeasures for space and ground-based crews for circadian phase resetting and alertness levels. The investigators propose to test the combined effects of these two countermeasures to determine whether adding exercise to light stimuli will further improve circadian phase resetting and alertness.
