Sang Min Park, Dong-Kyu Kim
Drug-induced sleep endoscopy (DISE) is a reliable upper airway evaluation tool, widely used to improve surgical results in patients with obstructive sleep apnea (OSA). Several factors, including sleeping position and depth of sedation, affect DISE findings. This study aimed to evaluate the impact of physical stress on DISE findings. Eighty-five patients with OSA underwent two DISE examinations at the same level of sedation. The "first DISE" (control group) was performed after polysomnography, while the "second DISE" (test group) performed immediately after a treadmill stress test...

BACKGROUND AND OBJECTIVE: Inadequate sleep patterns may be considered a trigger to development of several metabolic diseases. Additionally, sleep deprivation and poor sleep quality can negatively impact performance in exercise training. However, the impact of sleep duration and sleep quality on performance during incremental maximal test performed by healthy men is unclear. Therefore, the purpose of the study was to analyze the association between sleep pattern (duration and quality) and performance during maximal incremental test in healthy male individuals...

BACKGROUND: Chronic pain is defined as pain lasting beyond normal tissue healing time, generally taken to be 12 weeks. It contributes to disability, anxiety, depression, sleep disturbances, poor quality of life, and healthcare costs. Chronic pain has a weighted mean prevalence in adults of 20%.For many years, the treatment choice for chronic pain included recommendations for rest and inactivity. However, exercise may have specific benefits in reducing the severity of chronic pain, as well as more general benefits associated with improved overall physical and mental health, and physical functioning...

Sleep has been postulated to promote brain energy restoration. It is as yet unknown if increasing the energy availability within the brain reduces sleep need. The guanidine amino acid creatine (Cr) is a well-known energy booster in cellular energy homeostasis. Oral Cr-monohydrate supplementation (CS) increases exercise performance and has been shown to have substantial effects on cognitive performance, neuroprotection and circadian rhythms. The effect of CS on cellular high-energy molecules and sleep-wake behaviour is unclear...

Hypothesis The hypotheses of all the four included studies share the common idea that it is possible to augment the effect of antidepressant drug treatment by applying different interventions and with each intervention attain a clinically meaningful better effect compared to a control condition, and with minor side effects, thus improving the short- and medium-term outcome in major depression. Procedures Study design The basic study design has been the double blind randomised controlled trial (RCT). In the light therapy study, all patients were treated with sertraline for the whole of the study duration...

The self-management of acute postoperative pain is not well researched. This cross-sectional study investigates postoperative pain and pain self-management behavior. We recruited 127 patients who underwent total knee or total hip arthroplasty in an acute care hospital. We measured postoperative pain intensity and pain self-management behavior for three postoperative days. The results showed that the participants experienced mild and moderate pain intensity and perceived moderate to severe pain interference, which influenced their mood, sleep patterns, ability to walk, and performance of general activities and rehabilitation exercises...
