ObjectiveTo compare the incidence of postoperative shivering between female patients undergoing gynecological and general surgery and to examine perioperative factors associated with postoperative shivering. MethodsThis retrospective study included 12 186 patients who underwent gynecological or general surgery between January 1， 2022， and March 15， 2024， of whom 10 884 female patients constituted the primary analysis population. Among the female patients， 1：1 nearest-neighbor propensity score matching was performed using a caliper of 0.02 on the raw propensity score scale， with exact matching on American Society of Anesthesiologists （ASA） physical status. After matching， the incidence of postoperative shivering was compared using the McNemar test. Conditional logistic regression stratified by matched pair was used to assess the associations of surgical categories and perioperative factors with postoperative shivering. ResultsBefore propensity score matching， the incidences of postoperative shivering were 2.98% （28/940） in the general surgery group and 4.94% （491/9 944） in the gynecological surgery group （P=0.007）. After matching， 881 matched pairs were obtained， and the absolute standardized mean differences （SMDs） for all covariates were < 0.10. The incidences of postoperative shivering were 3.06% （27/881） in the general surgery group and 4.99% （44/881） in the gynecological surgery group. The McNemar test without continuity correction yielded P=0.044， whereas the exact McNemar test showed a P value of 0.057. Unifactorial conditional logistic regression showed that gynecological surgery was associated with higher odds of postoperative shivering than general surgery ［odds ratio （OR）=1.63， 95% confidence interval （CI）： 1.01-2.63， P=0.046］. However， the association was not statistically significant in the multifactorial conditional logistic regression ［adjusted odds ratio （aOR）=1.62， 95%CI： 0.78-3.37， P=0.197］. Each 30-min increase in the duration of surgery was associated with 32% higher odds of postoperative shivering （aOR=1.32， 95%CI： 1.07-1.62， P=0.009）. Each 1 °C increase in the minimum intraoperative body temperature was associated with lower odds of postoperative shivering， although the association did not reach statistical significance （aOR=0.32， 95%CI： 0.10-1.02， P=0.053）. ConclusionAfter propensity score matching， the incidence of postoperative shivering was higher among female patients undergoing gynecological surgery than among those undergoing general surgery； however， neither the exact comparison nor the adjusted association reached statistical significance. A longer duration of surgery was associated with higher odds of postoperative shivering， whereas a higher minimum intraoperative body temperature may be associated with lower odds.

OBJECTIVES: Whether vortioxetine has a utility as an adjuvant drug in the treatment of bipolar depression remains controversial. This study aimed to validate the efficacy and safety of vortioxetine in bipolar depression. METHODS: Patients with bipolar Ⅱ depression were enrolled in this prospective, two-center, randomized, 12-week pilot trial. The main indicator for assessing treatment effectiveness was a Montgomery-Asberg Depression Rating Scale (MADRS) of ≥50%. All eligible patients initially received four weeks of lurasidone monotherapy. Patients who responded well continued to receive this kind of monotherapy. However, no-response patients were randomly assigned to either valproate or vortioxetine treatment for eight weeks. By comprehensively comparing the results of MADRS over a period of 4‍‒‍12 weeks, a systematic analysis was conducted to determine whether vortioxetine could be used as an adjuvant drug for treating bipolar depression. RESULTS: Thirty-seven patients responded to lurasidone monotherapy, and 60 patients were randomly assigned to the valproate or vortioxetine group for eight weeks. After two weeks of combined valproate or vortioxetine treatment, the MADRS score in the vortioxetine group was significantly lower than that in the valproate group. There was no difference in the MADRS scores between the two groups at 8 and 12 weeks. The incidence of side effects did not significantly differ between the valproate and vortioxetine groups. Importantly, three patients in the vortioxetine group appeared to switch to mania or hypomania. CONCLUSIONS This study suggested that lurasidone combination with vortioxetine might have potential benefits to bipolar II depression in the early stage, while disease progression should be monitored closely for the risk of switching to mania.

With the widespread adoption of lung cancer screening, an increasing number of patients are being diagnosed with early-stage lung adenocarcinoma. For stage ⅠA lung adenocarcinoma, sublobar resection is the primary treatment approach. However, in patients with concomitant spread through air space (STAS), numerous studies advocate for lobectomy as the mainstay of treatment. Due to the limitations in preoperative prediction and intraoperative frozen section evaluation for assessing STAS, current research is largely restricted to using clinical and imaging features to predict STAS occurrence, with results that are inconsistent and unsatisfactory. Furthermore, most studies focus on individual clinical or imaging characteristics, and there is a lack of large-sample investigations. The rise of artificial intelligence in recent years has provided new insights into solving this problem, and existing studies have shown that artificial intelligence demonstrates better performance in STAS prediction compared to conventional methods. This article reviews the value of artificial intelligence in predicting STAS.

Objective To explore a new method for lacrimal passage irrigation after laser dacryocystoplasty surgery. Method One-hundred patients (104 eyes), which underwent laser dacryocystoplasty surgery combined with lacrimal drainage tube indwelling, were divided into two groups. In Group A (50 patients, 52 eyes), lacrimal passage irrigation was performed by traditional No.5 needle. While in Group B (50 patients, 52 eyes), it was done by No.7 blunt round needle designed by the researchers. Lacrimal passage irrigation was performed three times, each at the 3rd day, 1 week and 1 month after surgery. The silicone tube was removed 3 months after surgery and the treatment was evaluated. Results The total effective rate was 64% (32/50) in Group A and 92%(46/50) in Group B. The difference was statistically significant (χ2=18.537, P < 0.01). Conclusions The No.7 blunt round needle showed better effect when used for lacrimal passage irrigation after laser dacryocystoplasty surgery. It could improve the efficiency of lacrimal passage irrigation, thus decreasing irrigation times and reducing psychological pressure for the patients, which is worthy of clinical application.
