Abnormal melatonin secretion has been strongly associated with the development of sleep disorders, which are recognized as significant risk factors for various chronic diseases. This article aims to comprehensively examine the diverse physiological functions of melatonin beyond its role in regulating circadian rhythms and the sleep-wake cycle, while analyzing its mechanisms of action in modulating oxidative stress, anti-inflammatory responses, and mitochondrial function.

Standard treatments for managing sleep disorders, which mainly include cognitive behavioral therapy and pharmacotherapy, have provided inconsistent results. Non-invasive brain stimulation (NIBS) has been proposed as another potential strategy for improving sleep quality in PD. We conducted a systematic review and Bayesian network meta-analysis (NMA) following the grading of recommendations, assessment, development, and evaluation (GRADE), to determine whether NIBS improves sleep quality and architecture in PD. Evidence from twenty-four studies, including 792 individuals with PD in the early-to-severe disease stages, was summarized. Our NMA indicated that low-frequency repetitive transcranial magnetic stimulation over the dorsolateral prefrontal cortex (rTMS; 0.54, 95 %CrI: 0.13,0.93; moderate certainty) may ameliorate subjective sleep quality compared to a control condition.

To investigate their efficacy in OSA, we performed a systematic literature search following PRISMA and Cochrane Handbook guidelines for studies reporting apnea-hypopnea index (AHI) and incretin-based therapy in patients with OSA. Only randomized controlled trials were eligible for inclusion. Our literature search identified 813 publications, and 5 articles met the inclusion criteria. Collectively, the studies enrolled 1024 patients, lasted ≥12 weeks with liraglutide or tirzepatide, and resulted in significant reductions in body weight and/or body mass index. Incretin-based therapies were also associated with AHI reduction, with a mean change of −14.45 events/h (95 % CI: 25.90 to −2.99, p < 0.001). By pooling data of 5 RCTs in a pairwise meta-analysis, incretin-based therapies showed a greater effect on AHI than usual care, with a mean difference of −11.61 events/h (95 % CI: 22.91 to −0.31, p = 0.046).
