Background: Obesity and chronic pain are related in both directions, according to earlier observational research.This research aimed to analyze the causal association between obesity and chronic pain at the genetic level, as well as to assess whether common factors mediate this relationship. Methods: This study used bidirectional two sample Mendelian randomization (MR) technique to analyze the association between obesity and chronic pain. Obesity's summary genome-wide association data were obtained from European ancestry groups, as measured by body mass index (BMI), waist-to-hip ratio, waist circumference (WC), and hip circumference (HC), genome-wide association study data for chronic pain also came from the UK population, including chronic pain at three different sites (back, hip, and headache), chronic widespread pain (CWP), and multisite chronic pain (MCP). Secondly, a two-step MR and multivariate MR investigation was performed to evaluate the mediating effects of several proposed confounders. Results: The authors discovered a link between chronic pain and obesity. More specifically, a sensitivity analysis was done to confirm the associations between greater BMI, WC, and HC with an increased risk of CWP and MCP.Importantly, the intermediate MR results suggest that education levels and smoking initiation may mediate the causal relationship between BMI on CWP, with a mediation effect of 23.08% and 15.38%, respectively. Conclusions The authors’ findings demonstrate that the importance of education and smoking in understanding chronic pain’s pathogenesis, which is important for the primary prevention and prognosis of chronic pain.

Objective:To analyze the impact of diagnosis-intervention packet payment (DIP) reform on hospitalization service capacity and patients′ economic burden, for references for promoting China′s medical insurance payment reform.Methods:Data were collected from the discharge summarizes of 116 545 hospitalized patients from a tertiary hospital in Guangdong Province. Among them, there were 42 534 cases before the DIP reform (January 2016 to December 2017) and 74 011 cases after the reform (January 2018 to December 2020). The all-cause in-hospital mortality rate, length of hospital stay, disease severity, readmission rate within 30 days, total hospitalization costs, and patient out of pocket expenses were used as evaluation indicators for hospitalization service capacity and patient economic burden. Intermittent time series analysis was conducted to examine the changes in indicators before and after DIP reform.Results:The slope of the change trend of all-cause in-hospital mortality rate and readmission rate within 30 days before and after DIP reform was not statistically significant ( P<0.05); The length of hospital stay showed a decreasing trend before the reform ( P=0.047), but the trend after the reform was not statistically significant ( P=0.776); The change trend of disease severity before the reform was not statistically significant ( P=0.682), but showed a significant upward trend after the reform ( P=0.012); The total hospitalization costs significantly increased during the reform ( P<0.001), but the trend of change after the reform was not statistically significant ( P=0.431); The patient′s out of pocket expenses showed an upward trend before the reform ( P=0.001), but the change trend after the reform was not statistically significant ( P=0.757). Conclusions:DIP reform could help hospitals improve their inpatient service capabilities and enhance their functional positioning; Strengthen medical cost management and control the increase in economic burden on hospitalized patients.

Objective:To evaluate the prognosis of patients with resectable pancreatic ductal adenocarcinoma (PDAC) treated by gemcitabine and nab-paclitaxel (AG) or AG combined with pro-grammed death-1 (PD-1) inhibitor regimen and application value of the Cleveland Clinic Foundation (CCF) risk score.Methods:The retrospective cohort study was conducted. The clinicopathological data of 151 PDAC patients who were treated by AG regimen or AG combined with PD-1 inhibitor regimen in Zhejiang Cancer Hospital from January 2013 to March 2024 were collected. There were 84 males and 67 females, aged (64±9)years. Observation indicators: (1) comparison of clinical characteristics among resectable PDAC patients with different CCF risk score; (2) analysis of influencing factors for overall survival time of resectable PDAC patients; (3) survival of resectable PDAC patients. Comparison of measurement data with skewed distribution between groups was conducted using the Mann-Whitney U test. Comparison of count data between groups was conducted using the chi-square test. Comparison of ordinal data between groups was conducted using the rank sum test. Univariate and multivariate analyses were conducted using the Cox regression model. Kaplan-Meier method was used to calculate survival rate and plot survival curve, and Log-rank test was used for survival analysis. Results:(1) Comparison of clinical characteristics among resectable PDAC patients with different CCF risk score. Based on CCF risk score, 102 of 151 patients were classified as low risk and 49 cases were classified as intermediate-to-high risk. There were signi-ficant differences in sex, age, smoking status, alcohol consumption, hypertension, and diabetes between the two categories ( P<0.05). (2) Analysis of influencing factors for overall survival time of resectable PDAC patients. Results of multivariate analysis showed that the treatment regimen was an indepen-dent influencing factor for overall survival time of resectable PDAC patients ( hazard ratio=1.976, 95% confidence interval as 1.065?3.666, P<0.05). (3) Survival of resectable PDAC patients. The follow-up time of 151 patients was 21.8(18.7,24.2)months, and the median overall survival time was 23.3(19.0,32.4)months. The follow-up time was 22.1(18.9,30.7)months of patients treated by AG regimen and 11.2(8.1,23.3)months of patients treated by AG combined with PD-1 inhibitor regimen, respectively. The median overall survival time of the two types of patients was 24.4(17.2,31.7)months and 16.9(8.9,24.9)months. The 1-year overall survival rates were 79.1% and 60.0%, and the 2-year overall survival rates were 53.4% and 28.5%, respectively. There was a significant difference in the overall survival between the two types of patients ( hazard ratio=1.913, 95% confidence interval as 1.041?3.516, P<0.05). Of the intermediate-to-high risk patients, the follow-up time was 18.5(8.8,28.1)months of 37 patients treated by AG regimen and 8.1(7.3,9.0)months of 12 patients treated by AG combined with PD-1 inhibitor regimen. The median overall survival time of the two types of patients was 32.4(15.7,49.0)months and 8.9(5.7,12.1)months, respectively. The 1-year overall survival rates were 82.7% and 31.3%, and the 2-year overall survival rates were 66.5% and 0, respectively. There was a significant difference in the overall survival between the two types of patients ( hazard ratio=5.402, 95% confidence interval as 1.811?16.118, P<0.05). Conclusions:The treatment regimen is an independent influencing factor for overall survival in patients with resectable PDAC. Compared with the AG combined with PD-1 inhibitor regimen, AG regimen is associated with good survival of patients with resectable PDAC. For patients classified as intermediate-to-high risk based on the CCF risk score, AG regimen is assiociated with a better overall survival compared to AG combined with PD-1 inhibitor regimen.

In January 2023, a patient with soft tissue degloving defect of right index, middle, ring and little fingers was treated in the Department of Hand Surgery, Suzhou Ruihua Orthopaedic Hospital. Seven free flaps from a leg were harvested to reconstruct the defected wound of fingers in primary surgery. Flap thinning and plastic surgery were performed in stage-II surgery. Over the 22 months of postoperative follow-up, the flaps in right index, middle, ring and little fingers survived well with the colour and texture close to proximal skin. There was no obvious swelling of the flaps and sensation of the flaps recovered to S 3. The donor sites healed well and the donor leg walked normally.
