The relationship between sleep dynamics and blood pressure (BP) changes is well established. Moreover, sleep efficiency and wakefulness during sleep (WASO) events have a significant impact on BP dipping. Despite this knowledge, there is limited research on the measurement of sleep dynamics and continuous blood pressure (CBP). This study aims to explore the relationship between sleep efficiency and cardiovascular function indicators such as pulse transit time (PTT), as a biomarker of CBP, and heart rate variability (HRV), measured using wearable sensors. The results of the study conducted on 20 participants at the UConn Health Sleep Disorders Center suggest a strong linear relationship between sleep efficiency and changes in PTT (r = 0.8515) and HRV during sleep (r = 5886). The findings of this study contribute to our understanding of the relationship between sleep dynamics, CBP, and cardiovascular health.

Background: An aging population in combination with more gentle and less stressful surgical procedures leads to an increased number of operations on older patients. This collectively raises novel challenges due to higher age heavily impacting treatment. A major problem, emerging in up to 50% of cases, is perioperative delirium.

Background: Ramadan fasting is a religious observance practiced regularly by Muslims and may have an effect on sleep quality, especially for athletes. Our systematic review with meta-analysis aims to identify the effect of Ramadan observance on the sleep patterns of athletes and non-athletes during Ramadan fasting over the teen years (2014-2024).
Study Design: A systematic search of Scopus, Web of Science, and Pubmed, was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-analyses.

Multimodal digital health assessments overcome the limitations of patient-reported outcomes by allowing for continuous and passive monitoring but remain underutilized in older adult lifestyle interventions for brain health. Therefore, we aim to (1) report ecological momentary assessment (EMA) and ActiGraph adherence among older adults during a lifestyle intervention; and (2) use dynamic data collected via EMA and ActiGraph to examine person-specific patterns of mindfulness, steps, and sleep throughout the intervention. We analyzed EMA and ActiGraph data from a pilot study of the 8-week My Healthy Brain program (N = 10) lifestyle group for older adults (60+) with subjective cognitive decline.

This study aimed to assess the test-retest reliability and validity of the Arabic version of the Pittsburgh Sleep Quality Index (A-PSQI), a 19-item sleep evaluation tool, in a population of medical students and interns in Saudi Arabia. Following a 16-person pilot study, 202 participants completed 2 A-PSQI questionnaires with a 2-week test-retest interval to avoid a carryover effect. Statistical analysis using RStudio included Cronbach alpha, Spearman rank correlation, and the intraclass correlation coefficient (ICC).

Background: Mild cognitive impairment (MCI) has a high risk of progression to Alzheimer's disease. The disease is often accompanied by sleep disorders, and whether sleep disorders have an effect on brain function in patients with MCI is unclear.
Aim: To explore the near-infrared brain function characteristics of MCI with sleep disorders.
