Eating Window and Sleep Disorders on Glycemic Control, Cardiovascular Risk, and Weight Loss
The study will be conducted at the Endocrinology and Hypertension Clinic of the São José do Rio Preto Medical School from 2025 to 2027, aiming to collect data for a thorough analysis of the participants. The study participants will be randomly assigned to 2 groups (intervention 1 and intervention 2). Participants in the first group will follow a daytime eating window (7 am - 7 pm). Participants in the second group will follow a nighttime eating window (12 pm - 12 am). Nutritional consultations will be individual and will occur once every 3 months until the conclusion of the study, according to the clinic's scheduling availability. The average duration of each session will be approximately 1 hour per participant. All participants will be reminded of their appointments via phone/WhatsApp.

Ketamine Versus Magnesium Sulfate in the Time and Awakening Quality of General Anesthesia.
Intervention: the sample of participants will be distributed in 4 groups. The placebo (PG) group will receive 100 ml of saline solution 15 min before anesthetic induction. The ketamine group (KG) will receive 0.3 mg / kg of ketamine in saline (total volume of 100 ml) 15 min before anesthetic induction. The magnesium sulfate group (SG) will receive 40 mg / kg of magnesium sulfate in saline solution (total volume of 100 ml) 15 min before anesthetic induction. The mixed group (MG) will receive 0.15 mg / kg of ketamine + 20 mg / kg of magnesium sulfate in saline solution (total volume of 100 ml) 15 min before anesthetic induction. All participants will be submitted to balanced anesthesia. Anesthetic induction will be started after 5 min of pre-oxygenation, with lidocaine 1.5 mg / kg, fentanyl 3 µg / kg, propofol until clinical hypnosis, cisatracurium 0.1 mg / kg and intubation after adequate neuromuscular relaxation. Maintenance will be with sevoflurane in concentration under clinical demand, repeating boluses of fentanyl 1 µg / kg and cisatracurium 0.03 mg / kg, as needed. Primary Outcomes: time between the end of anesthetic administration and bispectral index (BIS) > 60, and a battery of neuropsychological tests to assess postoperative cognitive dysfunction tested in the Brazilian population 3 h after the end of anesthetic administration. Secondary Outcomes: response to the brief pain inventory questionnaire and opioid consumption in the first 2 postoperative days. Recruitment and timeline : patients will be recruited in the pre-anesthetic evaluation and assessments will be made of covertly in the immediate postoperative period and during the two days after surgery, being registered the pain scores and the consumption of opioids. Sample calculation: the sample of 120 participants was calculated with a 95% confidence index and 80% statistical power. To compensate for losses, 140 individuals will be recruited.
