ObjectiveTo evaluate the safety and efficacy of oxycodone versus sufentanil for postoperative analgesia in patients with moderate to severe obstructive sleep apnea (OSA) undergoing uvulopalatopharyngoplasty (UPPP). MethodsWe enrolled 73 consecutive patients with moderate-to-severe OSA (confirmed by polysomnography) scheduled for elective UPPP under general anesthesia at our institution between August 2023 and August 2025. Patients were randomly assigned to receive oxycodone (n = 37) or sufentanil (n = 36) using a random number table . The sufentanil group received 1.5 μg per kilogram of body weight, and the oxycodone group received 0.9 mg per kilogram; both groups used patient-controlled intravenous analgesia (PCIA) pumps with a total volume of 100 mL. A 2 mL loading dose was administered 10 minutes before the end of surgery, followed by a background infusion of 2 mL per hour, 2 mL bolus doses on demand, an 8-minute lockout interval, and a maximum hourly volume of 10 mL. We assessed pain scores (Numerical Rating Scale) at rest and during swallowing, Ramsay sedation scores, morphine-equivalent opioid consumption, PCIA bolus demands, patient satisfaction, time to first oral intake, and adverse events (including respiratory depression, nausea, and vomiting) at 4, 12, 24, and 48 hours postoperatively. ResultsBaseline characteristics were well balanced between the two groups (all P>0.05). No significant between-group differences were observed in resting and swallowing NRS scores or Ramsay sedation scores at each postoperative time point, PCIA satisfaction, time to first oral intake, or adverse event incidence across all postoperative time points (all P>0.05). Morphine-equivalent opioid consumption was significantly lower in the oxycodone group at all time points, as were unsuccessful PCIA bolus demands at 24 and 48 hours postoperatively (both P<0.05). ConclusionsLow-dose oxycodone provided analgesic efficacy similar to that of sufentanil for PCIA after UPPP in patients with moderate-to-severe OSA, with no significant between-group differences in adverse events, time to first oral intake, or satisfaction .The oxycodone group had numerically lower adverse event rates and a shorter time to first oral intake, suggesting a favorable safety profile and potential benefits for reducing opioid-related events and facilitating earlier recovery in this patient population.

Objective:
To establish a risk prediction model for diabetic peripheral neuropathy (DPN) among patients with type 2 diabetes mellitus (T2DM), so as to provide a basis for DPN prevention and control.
Methods:
T2DM inpatients aged 18-65 years admitted to the department of endocrinology and metabolism at Affiliated Hospital Shandong Second Medical University from April to December 2024 were selected as study subjects. Age, T2DM duration, hypertension history, 25-hydroxyvitamin D, serum C-peptide, and high density lipoprotein cholesterol (HDL-C) were collected through electronic medical records. Risk predictors of DPN among T2DM patients were screened using multivariable logistic regression model, and a nomogram was established. The receiver operating characteristic (ROC) curve, calibration curve and decision curve analysis were employed to evaluate the discrimination, calibration and clinical utility of the nomogram, respectively.
Results:
A total of 598 T2DM patients were enrolled, including 359 (60.03%) males and 239 (39.97%) females. The median age was 54.50 (interquartile range, 15.00) years, the median T2DM duration was 6.00 (interquartile range, 9.00) years. There were 262 cases of T2DM patients with DPN, accounting for 43.81%. Multivariable logistic regression identified hypertension history (OR=3.260, 95%CI: 2.220-4.790), alcohol use history (OR=2.150, 95%CI: 1.390-3.310), diabetes complications (OR=0.430, 95%CI: 0.270-0.680), T2DM duration (OR=1.040, 95%CI: 1.010-1.070), body mass index (OR=1.130, 95%CI: 1.070-1.200), 25-hydroxyvitamin D (OR=0.930, 95%CI: 0.910-0.960), and HDL-C (OR=0.400, 95%CI: 0.230-0.720) as risk predictors for DPN among T2DM patients. The area under the ROC curve of the established risk prediction model was 0.774 (95%CI: 0.737-0.812), with a sensitivity of 0.710 and a specificity of 0.723. The calibration curve after repeated sampling calibration approached the standard curve. Decision curve analysis showed that when the risk threshold probability was 0.2 to 0.4, the model demonstrates favorable clinical applicability.
Conclusion
The risk prediction model established in this study has favorable discrimination, calibration, and clinical utility, can effectively predict the risk of DPN among T2DM patients aged 18-65 years.

Abuse of amphetamine-based stimulants is a primary public health concern. Recent studies have underscored a troubling escalation in the inappropriate use of prescription amphetamine-based stimulants. However, the neurophysiological mechanisms underlying the impact of acute methamphetamine exposure (AME) on sleep homeostasis remain to be explored. This study employed non-human primates and electroencephalogram (EEG) sleep staging to evaluate the influence of AME on neural oscillations. The primary focus was on alterations in spindles, delta oscillations, and slow oscillations (SOs) and their interactions as conduits through which AME influences sleep stability. AME predominantly diminishes sleep-spindle waves in the non-rapid eye movement 2 (NREM2) stage, and impacts SOs and delta waves differentially. Furthermore, the competitive relationships between SO/delta waves nesting with sleep spindles were selectively strengthened by methamphetamine. Complexity analysis also revealed that the SO-nested spindles had lost their ability to maintain sleep depth and stability. In summary, this finding could be one of the intrinsic electrophysiological mechanisms by which AME disrupted sleep homeostasis.

The prefrontal cortex and hippocampus may support sequential working memory beyond episodic memory and spatial navigation. This stereoelectroencephalography (SEEG) study investigated how the dorsolateral prefrontal cortex (DLPFC) interacts with the hippocampus in the online processing of sequential information. Twenty patients with epilepsy (eight women, age 27.6 ± 8.2 years) completed a line ordering task with SEEG recordings over the DLPFC and the hippocampus. Participants showed longer thinking times and more recall errors when asked to arrange random lines clockwise (random trials) than to maintain ordered lines (ordered trials) before recalling the orientation of a particular line. First, the ordering-related increase in thinking time and recall error was associated with a transient theta power increase in the hippocampus and a sustained theta power increase in the DLPFC (3-10 Hz). In particular, the hippocampal theta power increase correlated with the memory precision of line orientation. Second, theta phase coherences between the DLPFC and hippocampus were enhanced for ordering, especially for more precisely memorized lines. Third, the theta band DLPFC → hippocampus influence was selectively enhanced for ordering, especially for more precisely memorized lines. This study suggests that theta oscillations may support DLPFC-hippocampal interactions in the online processing of sequential information.
