Filter by:Habitual short sleep duration (< 7 hours/night) increases the risk of cardiovascular disease (CVD) and all-cause mortality. Yet most adults, especially emerging adults (i.e., 18-25 years) do not achieve the National Sleep Foundation recommendation of 7-9 hours of sleep each night. Additionally, the American Heart Association recently included sleep duration in the "Life's Essential 8". This recent development emphasizes the importance of sleep and the need to advance our understanding of how sleep impacts cardiometabolic health (CMH), particularly in emerging adults, a population whose CVD risk trajectory is malleable. Specifically, emerging adulthood is a critical age window when age-related loss of CMH accelerates. Based on my previous work and others, both self-reported and objective measures of poor sleep (e.g., duration, variability) are linked to early signs of elevated CVD risk in emerging adults, such as microvascular dysfunction and elevated central blood pressure (BP), which precede the development of hypertension.
Acting adaptively requires quickly picking up on structure in the environment and storing the acquired knowledge for effective future use. Dominant theories of the hippocampus have focused on its ability to encode individual snapshots of experience, but the investigators and others have found evidence that it is also crucial for finding structure across experiences. The mechanisms of this essential form of learning have not been established. The investigators have developed a neural network model of the hippocampus instantiating the theory that one of its subfields can quickly encode structure using distributed representations, a powerful form of representation in which populations of neurons become responsive to multiple related features of the environment. The first aim of this project is to test predictions of this model using high resolution functional magnetic resonance imaging (fMRI) in paradigms requiring integration of information across experiences. The results will clarify fundamental mechanisms of how humans learn novel structure, adjudicating between existing models of this process, and informing further model development. There are also competing theories as to the eventual fate of new hippocampal representations. One view posits that during sleep, the hippocampus replays recent information to build longer-term distributed representations in neocortex. Another view claims that memories are directly and independently formed and consolidated within the hippocampus and neocortex. The second aim of this project is to test between these theories. The investigators will assess changes in hippocampal and cortical representations over time by re-scanning participants and tracking changes in memory at a one-week delay. Any observed changes in the brain and behavior across time, however, may be due to generic effects of time or to active processing during sleep. The third aim is thus to assess the specific causal contributions of sleep to the consolidation of structured information. The investigators will use real-time sleep electroencephalography to play sound cues to bias memory reactivation. The investigators expect that this work will clarify the anatomical substrates and, critically, the nature of the representations that support encoding and consolidation of novel structure in the environment.
Women with type 2 diabetes (n=150) experiencing ≥1 storage lower urinary tract symptoms and poor sleep health will be recruited from the outpatient departments or wards/units of the selected hospitals/clinics. Our study aims to examine the effects of conservative management incorporating urologic health promotion and sleep health promotion on relieving storage lower urinary tract symptoms and poor sleep, and on improving urologic health self-management behaviors and health-related quality of life. Women who agree to participate will be randomly assigned into the intervention group A, intervention group B, or comparison group. The intervention group A receives a 4-month conservative management with sleep hygiene related adjustments, pelvic floor muscle training, and urologic health promotion. The intervention group B receives a 4-month conservative management with brief behavioral treatment for insomnia (BBTI), pelvic floor muscle training, and urologic health promotion. The comparison group receives information related to pelvic floor muscle training and urologic health promotion, and receives a brief conservative management related to sleep hygiene adjustments after the completion of data collection. Information related to intervention effects is obtained by a questionnaire, a wristwatch-like actigraphy, and physical activity/diet/voiding/sleep logs from all participants at 4 data collection points: baseline, and 2-, 4-, 6-month follow-ups. Our study hypothesis is that the intervention effects on relieving storage lower urinary tract symptoms and poor sleep, and on improving urologic health self-management behaviors and health-related quality of life in the intervention group A or B are superior to the changes revealed in the comparison group.
The goal of this study is to learn about how children's sleep is related to their eating behaviors the next day, and to learn about factors that relate to eating behaviors and sleep health that are specific to preadolescent children living in rural communities.
Multiple Myeloma occurs with damaging bone lesion, hypercalcemia, anemia and renal failure as a result of secretion of monoclonal protein in serum and/or urea and accumulation of plasma cells. The most common symptoms at the time of diagnosis are; fatigue, insomnia, bone pain and recurrent infections. In multiple myeloma patients, pain, fatigue and sleep problems are conditions that significantly affect the daily life activities of the individual and require planned nursing interventions for the solution. In this challenging process, a holistic approach should be adopted while planning the care practices of the patients, and non-pharmacological practices should be planned, which will enable the patient to perform the activities of daily life with minimum energy and maximum function. Acupressure, one of the non-pharmacological applications, is a complementary medicine method that ensures the proper functioning of the energy channels by applying pressure to the points on the energy-carrying meridians (these points are the same as acupuncture points) with fingers, palms or wrist bands without using needles, unlike acupuncture. In the literature, it is stated that acupressure is a pain-relieving, relaxing analgesic and immune system-strengthening supportive method rather than its therapeutic effect, and it relieves insomnia and fatigue and relieves the person. In addition, within the scope of the harmonization model; By teaching acupressure to patients by nurses, patients can be actively involved in their own symptom management. Therefore, this study was planned to evaluate the effect of self-acupressure applied to patients with multiple myeloma on pain, fatigue and sleep quality. The research will be conducted as a randomized, experimental study with a pretest-posttest control group. The sample of the study will consist of 52 Multiple Myeloma patients, 26 experimental and 26 control groups, who met the research criteria and accepted the study, between August 2022 and January 2023, in Hematology Clinic and Polyclinic of Fırat University Hospital. Patients in the experimental group will be asked to perform self-acupressure by showing and teaching the LI4, HT 7, ST36 and SP6 acupressure points by the researcher. Depending on the preparation and compression time on these 4 points, the patients will be asked to perform a total of 16 sessions for 4 weeks, for a total of 18 minutes, 2 days a week in the morning and afternoon. The 1st measurement will be obtained by applying the Patient Information Form, Visual Analog Scale "Pitssburg Sleep Quality Index (PUKI)" and Piper Fatigue Scale" to the patients in the experimental group at the pre-test stage before the application. After 4 weeks, the Pitssburg Sleep Quality Index (PUKI) and The second measurement will be obtained by applying the "Piper Fatigue Scale" again. No application will be made to the patients in the control group. In the pre-test phase, the 1st measurement will be obtained by applying only the Patient Information Form, Visual Analog Scale, Pitssburg Sleep Quality Index (PUKI) and Piper Fatigue Scale. After 4 weeks, in the post-test phase, the second measurement will be obtained by re-applying the other forms except the Patient Information Form. The data will be analyzed using the SPSS 23 program. Shapiro Wilk test, t test, Mann-Whitney U test, Wilcoxon test and Chi-square analysis will be used in the analysis of the data.
We aim to test whether quality of sleep in working people can be improved by modulating the gut microbiome with probiotics.
To test the timing of evening tablet use on children's circadian phase and sleep (i.e., sleep onset and sleep duration) compared to no screen media use. To explore the effect of evening tablet use on children's inhibitory control and executive function.
This study is being done to find out whether extending sleep for at least an hour per night, seven days a week, predicts a higher tolerance and a higher threshold for pain. This is a 21-day study. Participants will be asked to wear sleep- and heart- monitoring watches. Pressure pain and cold pain will be measured at study visits.
