Objective To analyze the efficacy of autologous tissue repair for rectocele through the perineal approach in treating constipation and fecal incontinence in patients.Methods From January 2021 to November 2022,23 female patients with symptomatic rectal protrusion were treated with perineal autologous tissue repair.Preoperatively and at 12 months postoperatively,the Cleveland Clinic Constipation Score(CCCS),Cleveland Clinic Incontinence Score(CCIS),and Patient Assessment of Constipation Quality of Life(PAC-QOL)questionnaires were used to assess postoperative outcomes and quality of life.Results Among the 23 patients,with a median follow-up time of 12.6 months,CCCS decreased from 17.09±1.68 to 3.96±2.08(P＜0.05);CCIS decreased from 1.52±4.15 to 0.52±1.41(P＞0.05);PAC-QOL:physical discomfort decreased from 13.00±1.51 to 4.74±1.98;psychological discomfort decreased from 20.96±3.27 to 5.74±2.67;concern and anxiety decreased from 26.13±4.37 to 8.78±3.14;satisfaction decreased from 15.39±2.35 to 4.60±1.59(P＜0.05).All patients showed significant improvement in constipation and incontinence symptoms postoperatively,with no serious postoperative complications and a marked improvement in postoperative quality of life.Conclusion Rectocele repair with perineal approach using autologous tissue is an effective and safe method,avoiding potential potential complications associated with grafts.

Objective:To investigate the effects of dexmedetomidine combined with butorphanol for sedation and analgesia on postoperative intracranial pressure and prognosis in patients with severe traumatic brain injury.Methods:A prospective randomized controlled study was conducted on 60 patients with severe traumatic brain injury who were admitted to the ICU after emergency craniotomy surgery at the South Campus of Shanghai Sixth People's Hospital Affiliated to Shanghai Jiao Tong University from August 2020 to December 2023. The patients were randomly assigned to two groups: the control group (C group, n = 30) and the dexmedetomidine combined with butorphanol group (DB group, n = 30). Based on the treatment recommendations from the 2016 Guidelines for the Management of Severe Traumatic Brain Injury, the DB group received a combination of dexmedetomidine and buprenorphine for sedation and analgesia. Dexmedetomidine was administered via intravenous infusion at a loading dose of 1 μg/kg over 10 minutes, followed by a continuous infusion of 0.4-0.7 μg/kg per hour. Butorphanol was given with a loading dose of 10 μg/kg, followed by a continuous infusion of 10-20 μg/kg per hour. The infusion rate was adjusted to maintain a target Richmond Agitation-Sedation Scale (RASS) score of -3 to -4 to ensure adequate sedation. Patients in the C group received a continuous infusion of an equal amount of 0.9% sodium chloride injection. RASS scores were evaluated in both groups every 4 hours and maintained for 72 hours. The blood pressure, heart rate, central venous pressure, intracranial pressure, RASS sedation scores, and Numerical Verbal Pain Scale pain scores were observed at each time point: upon admission to the ICU (T 1) as well as 24 hours (T 2), 48 hours (T 3), and 72 hours (T 4) after surgery. The number of ventilator days, length of stay in the ICU, and Glasgow Outcome Scale prognosis score at discharge were recorded for all patients. Additionally, the incidence of adverse events such as secondary pulmonary infections, rebleeding, secondary surgeries, and death during hospitalization was recorded. Results:The mean arterial pressure ( F = 69.02, P < 0.001), heart rate ( F = 127.19, P < 0.001), and intracranial pressure ( F = 53.36, P < 0.001) in the DB group were significantly lower compared with those in the C group. The RASS scores ( F = 8.00, P = 0.006) and Numerical Verbal Pain Scale scores ( F = 420.02, P < 0.001) in the DB group were significantly lower than those in the C group. Central venous pressure in the DB group was significantly higher than that in the C group ( F = 6.34, P = 0.015). In terms of clinical outcomes, the mortality rate in the DB group was significantly lower than that in the C group ( χ2 = 4.36, P = 0.037), and the Glasgow Outcome Scale prognosis score was significantly higher in the DB group ( t = 3.03, P = 0.004). The number of ventilator days ( t = 6.10, P < 0.001) and the length of stay in the ICU ( t = 7.71, P < 0.001) were significantly shorter in the DB group compared with the C group (both P < 0.05). There were no statistically significant differences in the incidence of pulmonary infections, rebleeding events, or secondary surgeries between the two groups (all P > 0.05). Conclusions:The combination of dexmedetomidine and butorphanol can effectively decrease postoperative intracranial pressure in patients with severe traumatic brain injury and improve their prognosis.

Background and Aims:Early-onset extensive emphysematous pancreatitis(EP)is a rare but highly lethal subtype of infected pancreatic necrosis(IPN),characterized by abrupt onset and rapid deterioration.This study aimed to investigate its clinical characteristics,microbiological spectrum,treatment approaches,and outcomes to provide evidence for early identification and timely intervention.Methods:A retrospective analysis was performed on 305 IPN patients treated at Xiangya Hospital,Central South University,from January 2010 to October 2023.Eight patients who developed gas accumulation involving≥50%of pancreatic or peripancreatic necrosis within two weeks of onset were defined as early-onset extensive EP.Their clinical data were compared with those of ordinary IPN patients.Results:Early-onset extensive EP accounted for 2.6%of all IPN cases.The early-onset extensive EP group had significantly higher mortality and multiple organ failure rates compared with the ordinary IPN group(75.0%vs.24.6%and 75.0%vs.34.7%,respectively;both P<0.05).A total of 15 microbial isolates were identified from early-onset extensive EP patients,predominantly Klebsiella pneumoniae(62.5%)and Escherichia coli(37.5%).The infection rate of carbapenem-resistant Enterobacteriaceae(CRE)was markedly higher in the EP group than in the ordinary IPN group(75.0%vs.31.1%,P=0.015).Most patients were treated using a step-up approach based on percutaneous catheter drainage,with no significant difference in treatment strategy between the two groups(P=0.625).Conclusion:Early-onset extensive EP represents a rare and fulminant subtype of IPN with extremely poor outcomes.Klebsiella pneumoniae and CRE are the predominant pathogens.Early radiological evaluation and timely intervention are crucial for improving prognosis in these patients.

Background::The disease burdens for endometrial cancer (EC) vary across different countries and geographical regions and change every year. Herein, we reported the updated results of the Global Burden of Disease Study 2019 on EC with respect to age-standardized incidence and mortality from 1990 to 2019.Methods::The annual percentage change (APC) of incidence and mortality was evaluated using joinpoint regression analysis to examine the temporal trends during the same timeframe in terms of the global landscape, different sociodemographic indices (SDI), and geographic regions. The relationship between Human Development Index (HDI) and incidence and mortality was additionally explored.Results::The age-standardized incidence rates (ASIRs) revealed a significant average global elevation by 0.5% per year (95% confidence interval [CI], 0.3–0.7; P <0.001). The age-standardized mortality rates (ASMRs), in contrast, fell by an average of 0.8% per year (95% CI, ?1.0 to ?0.7; P <0.001) worldwide. The ASIRs and ASMRs for EC varied across different SDIs and geographical regions. We noted four temporal trends and a significant reduction by 0.5% per year since 2010 in the ASIR, whereas we detected six consecutively decreasing temporal trends in ASMR during the entire period. Notably, the estimated APCs were significantly positively correlated with HDIs (ρ = 0.22; 95% CI, 0.07–0.35; P = 0.003) with regard to incident cases in 2019. Conclusions::Incidence rates for EC reflected a significant increase overall (although we observed a decline since 2010), and the death rates declined consecutively from 1990 to 2019. We posit that more precise strategies can be tailored and then implemented based on the distinct age-standardized incidence and mortality burden in different geographical areas.

Background and Aims:Accurate early pathogen diagnosis is a breakthrough for improving the prognosis of infectious pancreatic necrosis(IPN)patients.However,there is currently a lack of efficient methods for early identification of IPN in clinical settings.This study was performed to assess the application value of next-generation sequencing technology based on metagenomic capture(MetaCAP)in the pathogen diagnosis of IPN. Methods:A prospective study was conducted on 29 patients suspected of having acute necrotizing pancreatitis at Xiangya Hospital of Central South University between January and July 2024.Blood samples were tested using MetaCAP and conventional pathogen culture.The results of peritoneal fluid pathogen culture were used as the gold standard to compare the diagnostic efficacy of the two methods. Results:Due to three cases lacking peritoneal fluid culture results,a total of 26 cases were included in the final analysis.The overall mortality rate was 23.1％(6/26).During hospitalization,9 cases(34.6％)were diagnosed with IPN.The sensitivity and negative predictive value of MetaCAP for diagnosing IPN were significantly higher than those of conventional pathogen culture(77.8％vs.11.1％,P=0.031;86.7％vs.65.2％,P=0.032),while the differences in specificity(76.5％vs.88.2％,P=0.689)and positive predictive value(63.6％vs.33.3％,P=0.347)between the two methods were not statistically significant.The average detection time for MetaCAP was 33(20-49)h,while microbial culture took 125(45-142)h,with a significant difference(P＜0.001).The average cost for blood MetaCAP testing was 2 500 yuan per case,but it accounted for only 1.19％of the average hospitalization cost. Conclusion:MetaCAP has significant value in the early pathogen diagnosis of IPN,with a shorter detection time,good testing efficacy,and health-economic value,demonstrating a promising clinical application prospect.

Objective To analyze the relationship between the relevant imaging signs of the Bosniak classification system version 2019 and the benign or malignant of cystic renal masses(CRMs).Methods The CRMs were graded using the Bosniak classification system version 2019,and the overall inter-observer agreement,and the agreement between different subgroups were compared.In addition,the diagnostic value of benign and malignant lesions with weighted weakened imaging signs,redefined and quantified imaging signs in the Bosniak classification system after upgrading from version 2005 to version 2019 was analyzed.Results Fifty-six CRMs were enrolled,including 43 benign and 13 malignant lesions.Based on the Bosniak classification system version 2019,the overall inter-observer agreement was excellent(Kappa=0.881),while the agreement of ≤30 mm and MRI were moderate(Kappa=0.548,0.722).In the comparison of the differences between benign and malignant CRMs,there were significant differences between the groups in age,lesion maximum diameter,thick septa or cyst wall,number of septa ≥4,mural nodule,and enhancement(P＜0.05).In the logistic regression model,the mural nodule was the only imaging sign that was significantly correlated with the malignant CRMs[odds ratio(OR)=9.842,P=0.022].Conclusion The Bosniak classification system version 2019 has an excellent overall inter-observer agreement.When the lesions are small,MRI can provide more imaging details.The mural nodule is an independent risk factor for malignant CRMs.

Objective:To investigate the application value of metagenomic next-genera-tion sequencing (mNGS) in pathogenic diagnosis of suspected infected severe acute pancreatitis (SAP).Methods:The prospective study was conducted. The clinical data of 25 patients with suspected infected SAP who were admitted to the Xiangya Hospital of Central South University from May to September 2023 were collected. Upper limb venous blood samples of all the patients were collected for both of mNGS and routine pathogen microbial culture. Observation indicators: (1) grouping situations of the enrolled patients; (2) comparison of the diagnostic efficiency of mNGS and routine pathogen microbial culture; (3) results of peripheral blood pathogen microbial testing and peri-pancreatic effusion microbial culture; (4) testing time and cost. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M( Q1, Q3). Count data were expressed as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. Results:(1) Grouping situations of the enrolled patients. A total of 25 patients were selected for eligibility. There were 18 males and 7 females, aged 48(40,59)years. The duration of hospital stay of 25 patients was 30(20,50)days. The etiologies of 25 patients included 14 cases of hyperlipidemic pancreatitis, 8 cases of biliary pancreatitis, 1 case of alcohol-induced acute pancreatitis, and 2 cases of pancreatitis caused by other causes. Of the 25 patients, there were 17 cases with infected pancreatic necrosis (IPN) including 7 cases of death, and 8 cases with sterile pancreatic necrosis including no death. (2) Comparison of the diagnostic efficiency of mNGS and routine pathogen microbial culture. The positive rates of mNGS and routine pathogen microbial culture in diagnosis of suspected infected SAP were 72.0%(18/25) and 32.0%(8/25), respectively, showing a significant difference between them ( χ2=8.01, P<0.05). The sensitivity and negative predic-tive value of mNGS and routine pathogen microbial culture in diagnosis of IPN were 94.1%(16/17), 35.3%(6/17) and 85.7%(6/7), 35.3%(6/17), showing significant differences between them ( χ2=12.88, 5.04, P<0.05). The specificity and positive predictive value of mNGS and routine pathogen microbial culture in diagnosis of IPN were 75.0%(6/8), 75.0%(6/8) and 88.9%(16/18), 75.0%(6/8), showing no significant difference between them ( χ2=0, 0.82, P>0.05). (3) Results of peripheral blood pathogen microbial testing and peripancreatic effusion microbial culture. Of the 17 patients with IPN, 36 strains of pathogenic bacteria were detected by mNGS, and 6 strains were detected by routine pathogen microbial culture. There were 16 of 17 patients with IPN showing positive mNGS pathogenic testing, of which 13 cases were consistent with the pathogenic testing results of peri-pancreatic effusion microbial culture, showing a consistency rate of 76.5%(13/17). There were 6 pati-ents with IPN showing positive routine pathogen microbial culture, with a consistency rate of 35.3%(6/17) to peripancreatic effusion microbial culture. (4) Testing time and cost. Testing time of mNGS and routine pathogen microbial culture were (43±17)hours and (111±36)hours, showing a signifi-cant difference between them ( t=9.31, P<0.05). Testing cost of mNGS was (2 267±0)yuan/case, accoun-ting for 1.7% of the hospitalization expenses of (133 759±120 744)yuan/case. Testing cost of routine pathogen microbial culture was (240±0)yuan/case, accounting of 0.2% of the hospitalization expenses. Conclusion:mNGS has important value for early pathogenic diagnosis of suspected infected SAP, and has a high timeliness.
