Introduction: Studies have shown that narcolepsy patients may present with low serum acylcarnitine levels, demonstrating a dysfunctional beta fatty acid oxidation pathway in these patients.
Objective: Evaluate the therapeutic efficacy of L-carnitine as a treatment for narcolepsy patients.
Methods: This study runned in form of systematic review. The terms used for the search: ("narcolepsy"[MeSH Terms] OR "narcolepsy"[All Fields]) AND ("carnitine"[MeSH Terms] OR "carnitine"[All Fields] OR "l carnitine"[All Fields]). Were included all surveys published until January 2021, with the diagnosis of narcolepsy, that performed drug treatment with I-carnitine. The clinical endpoints of interest were: excessive daytime sleepiness, dissociative REM sleep manifestations: cataplexy, sleep paralysis, hypnagogic hallucinations, and early REM sleep (REM sleep naps, SOREMP).
Results: L-carnitine was found to be well-tolerated and without side effects in all surveys, at dosages ranging from 500 to 510 mg/day. Newborns did not present complications during delivery.
Conclusion: This study corroborates the efficacy and good tolerability of L-carnitine therapy as a treatment for patients with narcolepsy, including during pregnancy.

However, few studies have investigated the association between polysomnography (PSG)-derived sleep architecture and dementia incidence. We examined the relationship between sleep macro-architecture and dementia incidence across five US-based cohort studies from the Sleep and Dementia Consortium (SDC).

The purpose of this study was to evaluate how the first oral administration of suvorexant affects PSG results in patients with severe obstructive sleep apnea (OSA). Single-center, prospective study conducted in a nonrandomized, uncontrolled, unblinded fashion. Undiagnosed 64 patients with suspected OSA underwent first-night PSG, and 30 patients with severe OSA (Apnea Hypopnea Index [AHI] ≥ 30 events/h) underwent second-night PSG testing after administration of 15 mg suvorexant.

Purpose: The aim of this study was to investigate the effect of general anesthesia combined with transversus abdominis plane block on postoperative sleep disorders in elderly patients undergoing gastrointestinal tumor surgery.
Methods: For elderly patients with gastrointestinal malignant tumors, we recruited 94 patients, aged 65-80, who were scheduled for radical laparoscopic surgery. Using the random number table method, the patients were randomly divided into two groups, the general anesthesia group (group GA) and the general anesthesia combined with transversus abdominis plane block group (group GT).
