Article The Effect of Preoperative Melatonin Patches on Sleep Quality in Patients Undergoing Urological Surgery(Assoc Medica Brasileira, 2026) Akok, Selin Ayten; Akinci, Naile; Toprak, ÇağlaOBJECTIVE: The aim of this study was to determine the effects of transdermal melatonin patches on sleep quality in patients undergoing urological surgery. METHODS: This study is a randomized controlled trial. Fifty-seven patients hospitalized in the urology department of a university hospital in Istanbul were included. Patients were randomly assigned to two groups (melatonin and control). Patients in the melatonin group received transdermal melatonin containing 7 mg of melatonin at 11:00 PM in a quiet, darkened room the night before surgery. RESULTS: According to the results of this study, Richards-Campbell Sleep Scale sleep-quality scores increased significantly in the melatonin group (p<0.001). The control group showed lower sleep-quality scores. In addition, a statistically significant decrease was observed between the visual analog scale well-being scores before and after the application in the melatonin group (p<0.001). CONCLUSION: In this study, our results showed that melatonin patches improved sleep quality and psychological well-being in patients undergoing urological surgery.Article Citation - WoS: 6Citation - Scopus: 5The Effect of Melatonin on Glycoprotein Levels and Oxidative Liver Injury in Experimental Diabetes(Wiley, 2023) Ertik, Onur; Sener, Goksel; Yanardag, RefiyeIn this present study, the duration of melatonin (Mel) administered to diabetic rats was prolonged so as to examine its effects on the biochemical liver parameters of diabetic rats. In the experiment, Male Sprague Dawley rats were divided randomly into five groups; the control, diabetic + Mel, diabetic, diabetic + insulin, and diabetic + Mel + insulin. Diabetes mellitus was induced by administration of a single dose of streptozotocin (60 mg/kg) intraperitoneally and rats were given vehicle as a solvent for Mel every day for 12 weeks. In the diabetic + Mel group, diabetic rats were administered Mel (10 mg/kg/day) for 12 weeks to treat diabetes. The diabetic + insulin group were diabetic rats given insulin (6 U/kg) subcutaneously for 12 weeks. The diabetic + Mel + insulin rats received insulin and Mel at the same dose and time. At the end of the experiment, the animals were decapitated and liver tissues were taken. The protective effect of Mel on liver tissue of diabetic rats was investigated, total antioxidant status, total oxidant status, reactive oxygen species, oxidative stress index, adenosine deaminase, xanthine oxidase, paraoxonase 1, sodium/potassium ATPase, myeloperoxidase, gamma-glutamyl transferase, sorbitol dehydrogenase, tumor necrosis factor-alpha, homocysteine, nitric oxide, glucose-6-phosphate dehydrogenase, and glycoprotein levels were determined in liver tissues. Treatment with Mel and/or insulin has been found to have a protective effect on biochemical parameters. The results showed that administration of Mel to diabetic rats prevented the distortion of the studied biochemical parameters of liver tissues.
