Objective: This trial was to examine the effect of transcutaneous electrical acupoint stimulation (TEAS) on postoperative cognitive function in older patients who underwent thoracoscopic pulmonary resection.
Methods: This was a prospective, randomized, double-blind, placebo-controlled study. 128 patients scheduled for surgery were randomly assigned to the TEAS group and sham-TEAS group. A standardized intervention of TEAS or sham-TEAS on the acupoints of Baihui (DU20) and bilateral Neiguan (PC6), Hegu (LI4), and Zusanli (ST36) from 30 min before anesthesia induction until the end of the surgery, combined with a general anesthetic protocol performed in the two groups respectively. The primary outcome was the incidence of postoperative cognitive dysfunction (POCD) assessed via the Montreal Cognitive Assessment (MoCA) scale at each time point. The secondary outcomes included the results of the Mini-Mental State Examination (MMSE) score, the Numerical Rating Scale (NRS) on pain and sleep, the European Organization for Research and Treatment of Cancer Quality of Life (EORTC-QLQ-C30), and a chronic pain questionnaire at relative time points.
Results: Participants who completed the 12-month trial of the two groups were well-matched in baseline demographic and clinical parameters. At postoperative day 1, day 7, and day 30 time points, the incidence of POCD in the sham-TEAS group was always significantly higher than in the TEAS group (65.4% vs 20%, 43.6% vs 7.3%, 40% vs 3.6%, all P < 0.001). Also, the TEAS group showed better scores of MMSE, sleep, and pain compared with the sham-TEAS group (all P < 0.001). At 6 and 12 months points, the global health scores of the TEAS group were still significantly higher than the sham-TEAS group, and the prevalence of chronic pain was significantly lower than the sham-TEAS group (all P < 0.05).
Conclusion: TEAS could effectively improve the postoperative cognitive function and long-term life quality of geriatric patients with lung cancer.

Perioperative neurocognitive disorders (PNDs) refer to a wide spectrum of cognitive impairment persisting days to even after a year postoperative with significant morbidity and mortality. However, despite much efforts involving perioperative managements, PNDs are still prevalent with no standard preventative and therapeutic strategy. To overcome PNDs, a better understanding of pathophysiology of PNDs is crucial and a large number of studies have proven that immune-inflammatory responses from surgical stress are involved in the abnormal activation of the hypothalamic-pituitary-adrenal (HPA) axis and destabilization of neurovascular unit (NVU) that lead to PNDs.

Unlabelled: The purpose of the study: to evaluate the impact of a comprehensive rehabilitation program on physical health indicators, such as weight restoration and improvement of functional capabilities of patients, psychoemotional state of patients, reduction of complications after surgical treatment.
Material And Methods: Observations were conducted on 148 patients diagnosed with melanoma of various localizations, who were divided into two groups by simple randomization: study (=77) and control (=71). The study group received surgical treatment in combination with rehabilitation programs (psychotherapy, nutritional support, general magnetic therapy), while the control group received only standard surgical treatment.
Cognitive Behavioural Therapy to Optimize Post-Operative Recovery (COPE): a randomized controlled feasibility trial in extremity fracture patients.
Pilot Feasibility Stud

Department of Health Research Methods, Evidence, and Impact, McMaster University, Hamilton, ON, Canada.
Article Synopsis
- The study aimed to assess the feasibility of an online cognitive behavioral therapy (CBT) program for patients recovering from extremity fractures compared to usual care.
- Despite enrolling 94 participants, recruitment showed a "yellow light," indicating some success but needing improvements.
- Compliance with the CBT program was low, as only 60% completed all modules, leading to a "red light," suggesting significant changes are necessary before a larger trial can proceed.

Objective: This study aimed to compare the clinical outcomes of midazolam and dexmedetomidine combined with ropivacaine-induced thoracic paravertebral nerve block (TPVB) in radical lung cancer surgery.
Methods: To retrospectively analyze the clinical data of elderly patients who underwent thoracoscopic radical lung cancer surgery from March 2020 to February 2023 in our hospital. All patients underwent a single two-site method of TPVB at the levels of T4 and T7 under ultrasound guidance.
