Background Sunshine duration is closely associated with population mental health and emotional states, although its relationship with mental and behavioral disorders (MBD) remains insufficiently studied. Objective To analyze the effect of sunshine duration on hospital admissions for MBD in Zigong City, Sichuan Province. Methods Hospital admission records for MBD from 10 medical institutions, meteorological data, and ambient air pollutant concentrations were collected in Zigong City from January 1, 2019 to December 31, 2024. A distributed lag non-linear model (DLNM) was employed to calculate single-day and cumulative lag effects of different sunshine duration exposures—0 h (P₀, P₅, P₂₅), 6 h (P₇₅), and 10.4 h (P₉₅)—on hospitalization risks for MBD, stratified by diagnostic category, sex, and age groups. Results This study analyzed 36597 hospital admissions for MBD in Zigong City. The exposure-response curve for sunshine duration at lag 0 d exhibited an inverted N-shaped pattern, with minimum relative risk (RR) of hospitalizations observed at 14 h sunshine duration. The immediate effects of different levels of sunshine duration on the hospitalization risk for MBD, schizophrenia, schizotypal and delusional disorders (SSDD), and neurotic, stress-related and somatoform disorders (NSSD) were significant, with the cumulative effect peaking at lags 12–13 days. For extremely short sunshine duration 0 h, the maximum relative risk (RR) values (with 95% confidence intervals, 95%CI) of hospitalization risk were 1.209 (1.001, 1.459) at lag 1 d for SSDD patients and 1.398 (1.133, 1.724) at lag 0 d for NSSD patients, respectively. The cumulative effect on hospitalization risk induced by short sunshine duration 6 h was higher than that induced by extremely short sunshine duration 0 h and long sunshine duration 10.4 h. Among populations stratified by gender and age, male patients and those aged over 70 years had higher hospitalization risks. For short sunshine duration 6 h, the cumulative RR (CRR) value (95%CI) of hospitalization risk for male MBD patients was 3.373 (1.362, 8.358) at cumulative lag 0–12 d, which was higher than that for female patients [2.943 (1.471, 5.889) at cumulative lag 0–13 d]. The population aged over 70 years was more sensitive to single-day and cumulative lag effects on hospitalization risk than other age groups. For short sunshine duration 6 h, the RR and CRR values (95%CI) of single-day and cumulative lag effects on hospitalization risk were 1.336 (1.002, 1.783) at lag 0 day and 5.085 (1.680, 15.392) at cumulative lag 0–12 d, respectively. At lag 13 d, long sunshine duration 10.4 h exposure was associated with depression hospitalizations in patients <20 years with RR=1.127 (95%CI: 1.002, 1.270). Conclusion When the daily sunshine duration is less than 14 h, it will increase the hospitalization risk of MBD in the population to varying degrees, with both single-day and cumulative lag effects. It is recommended that the public, especially vulnerable groups such as people with MBD aged 70 years and above and those with depression under 20 years, strengthen health protection to reduce the health risks caused by changes in sunshine.

Background: and Purpose In patients with large vessel occlusion (LVO), intravenous thrombolysis (IVT) frequently alters thrombus location; however, the clinical impact of this phenomenon remains unclear. We aimed to compare post-IVT thrombus dynamics between tenecteplase and alteplase and to evaluate the association between thrombus dynamics and 3-month outcomes. Methods: This retrospective study analyzed prospectively collected, multicenter data from consecutive patients with LVO who underwent bridging therapy between January 2022 and December 2024. Thrombus dynamics were classified as resolution, migration, or stability. Analyses incorporated propensity score matching with weighting to balance baseline characteristics. Results: Of the 806 initially included patients, 746 were included after matching (373 treated with tenecteplase and 373 treated with alteplase). The incidence of thrombus migration was significantly higher in the tenecteplase group than in the alteplase group (19.3% vs. 11.3%; odds ratio [OR]: 1.92; 95% confidence interval [CI] 1.27–2.91). The advantage of tenecteplase over alteplase was restricted to patients with an IVT-to-puncture time of <60 minutes (18.6% vs. 6.2%; p=0.001) and was no longer significant when the interval ≥60 minutes (19.7% vs. 15.0%; p=0.204; pinteraction=0.043). Additionally, thrombus migration was associated with a better functional outcome (OR: 1.62; 95% CI 1.04–2.53). Finally, tenecteplase was associated with improved functional independence compared with alteplase (OR: 1.43; 95% CI 1.04–1.95). Conclusions Tenecteplase demonstrated superior efficacy in inducing thrombus migration compared with alteplase, particularly within 60 minutes of IVT administration. Thrombus migration independently predicted improved functional independence. These findings support the preferential use of tenecteplase for bridging therapy in patients with LVO.

Objective The aim of this study was to analyze the clinical features,ultrasonographic manifestations,and medication characteristics of shoulder joint involvement in patients with rheumatoid arthritis during the course of the disease,and to explore the impact of shoulder joint involvement on the overall condition of RA,to further provide a basis for clinical diagnosis and treatment.Methods One hundred and forty RA patients who were hospitalized in our department between August 2023 and August 2024 were selected,and they were divided into the RA involving shoulder joint group and the non-involving group according to whether they were combined with shoulder pain or shoulder arthritis manifestations.The clinical data of the two groups were analyzed and compared,including disease activ-ity,imaging characteristics and treatment modalities.Results The RA-involved shoulder group was significantly higher than the non-involved group in pain visual analog scores,swelling,number of tender joints,28 arthropathic activity scores-erythrocyte sedimentation rate and C reactive protein scores,and the differences were statistically significant(P＜0.001).The two groups had significant differ-ences in blood tests,inflammation indexes,Rheumatoid factor and anti-CCP antibody and other laboratory tests were significantly differ-ent in the morning(P＞0.05),suggesting that shoulder joint involvement may not be readily recognized by routine laboratory tests.The ultrasonographic performance of RA involving the shoulder joint was classified into bilateral and unilateral lesions,in which the unilateral lesions were mostly acromioclavicular joint synovitis,and the bilateral lesions were predominantly humeral head bone erosions.Inflamma-tory changes of synovitis were predominantly in the acromioclavicular joint,while structural changes were focused on bone erosion of the humeral head.In patients with structural changes,the erythrocyte sedimentation rate and C-reactive protein level were higher than those of the group with inflammatory changes,and the difference was statistically significant(P＜0.05),while the difference between the rheu-matoid factor and the anti-CCP antibody was not statistically significant(P＞0.05).The proportion of patients with RA involving the shoulder joint using traditional synthetic antirheumatic drugs(csDMARDs)in combination with biologics(bDMARDs)or targeted syn-thetic antirheumatic drugs(tsDMARDs)was significantly higher,especially the proportion of csDMARDs in combination with bDMARDs was the most prominent.Conclusion Patients with RA who have shoulder involvement during the course of the disease usually present with worsening systemic symptoms,high disease activity,and ultrasonographic findings of synovitis and bone erosion in the shoulder joint.However,conventional laboratory tests and imaging methods lack specificity in the diagnosis of shoulder joint involvement,and therefore,clinical attention should be paid to shoulder joint involvement in RA to prevent disease progression from adversely affecting the overall prognosis.

The da Vinci Surgical System provides surgeons with a three-dimensional image view with greater clarity, which improves surgical precision, particularly in confined surgical spaces. Compared to laparoscopic surgery, robotic surgery has a shorter learning curve and may be a better choice for surgeons. However, some surgeons are susceptible to laparoscopic experience when performing robotic surgery, which can diminish the advantages of the robotic system. We discussed some key issues such as indications, use of energy instruments, surgical approach, lymph node dissection, and digestive tract reconstruction, from the habit of laparoscopic surgery, in light of our team's experience with robotic radical gastric cancer surgery and the latest literature, in order to help beginners better understand the robotic surgical system.

Objective:To investigate the feasibility and safety of laparoscopic purse- string suture clamps combined with multi-functional seal caps for esophagojejunal Roux-en-Y anastomosis during total laparoscopic radical total gastrectomy (TLTG).Methods:This was a retrospective descriptive study of 42 patients with primary gastric malignancies who underwent TLTG at the First Affiliated Hospital of Nanjing Medical University that utilized laparoscopic purse-string suture clamps and multi-functional seal caps for esophagojejunal anastomosis between May, 2024 and January, 2025. The cohort included 33 males and 9 females, with a mean age of (67.7 ±9.5) years and a mean body mass index (BMI) of (23.9±2.9) kg/m 2. The American Society of Anesthesiologists (ASA) physical status classifications were I - II in 40 patients and III in 2 patients, and all patients were definitively diagnosed preoperatively via gastroscopy, dual-energy CT, and/or MRI. Tumor locations included the gastroesophageal junction (GEJ) in 28 cases (Siewert type II - III), the upper third of the stomach in 12 cases, and the middle third in 2 cases. The median distance of esophageal invasion was 1.3 cm, though in 10 cases this was ≥2 cm. Preoperative TNM staging was I-II in 17 patients and III in 25 patients. Surgical outcomes including operative time, anastomosis time, intraoperative blood loss, pathological results, and postoperative recovery were retrospectively analyzed. Results:All 42 operations were successful. The mean operative time was(212.5±26.4) minutes, and the average time from multi-functional seal cap placement to completion of the esophagojejunal anastomosis was (54.2±7.5) minutes. Mean intraoperative blood loss was (79.9±21.3) ml. Postoperative pathology confirmed R0 resection in all specimens, with a mean proximal esophageal margin distance of (2.1±1.6) cm. Furthermore, (51.9±15.1) lymph nodes on average were harvested from each patient; the mean time to oral intake was (149.5±41.4) hours; and the mean hospital stay was (11.3±5.4) days. Postoperative complications occurred in 6 patients: anastomotic leakage ( n=2), residual intra-abdominal infection ( n=1), pulmonary infection ( n=3), and Clavien-Dindo grade III or higher complications occurred in 2 patients. No recurrence, mortality, or anastomosis-related complications were observed within a median follow-up of 5.8 months (range 3.5-11.2). Conclusion:We find the application of the laparoscopic purse-string suture clamps and multi-functional seal caps for esophagojejunal anastomosis in TLTG to be safe and feasible, with satisfactory short-term outcomes.
