OBJECTIVE To explore the influencing factors for successful detoxification in patients undergoing methadone maintenance therapy. METHODS A retrospective selection of 161 methadone maintenance therapy patients from the South Branch of Zhongshan Second People’s Hospital （including methadone maintenance treatment sites in Shiqi District， Xiqu District， Development Zone of Zhongshan City） from January 1， 2012， to January 1， 2025， was conducted as the study object. Data collected included patients’ sociodemographic information， drug abuse history， laboratory test results， medication records， etc. Patients were divided into the unsuccessful detoxification group and the successful detoxification group based on whether methadone detoxification was achieved. Univariate， univariate Cox regression， and multivariate Cox proportional hazards regression were used for influencing factor analysis， and the Kaplan-Meier method was employed for survival analysis. RESULTS Among the 161 methadone maintenance therapy patients， 96 were in the successful detoxification group and 65 in the unsuccessful detoxification group， yielding a successful detoxification rate of 59.63%. Multivariate Cox proportional hazards regression analysis revealed that age， registered residence status， age at first drug use， and duration of drug abuse were key influencing factors for successful detoxification in methadone maintenance therapy patients （P＜0.05）. Specifically， the successful detoxification rate for patients with Zhongshan local registered residence was 8.364 times higher than that for patients with non-local registered residence； for every 1-year increase in patient age， the successful detoxification rate decreased by 22.7%； for every 1-year increase in age at first drug use， the successful detoxification rate rose by 33.4%； and for every 1-year increase in duration of drug abuse， the successful detoxification rate increased by 33.5%. Survival analysis showed that the successful detoxification rate in the methadone low-dose group （≤30.8 mg） was significantly higher than that in the methadone high-dose group （＞30.8 mg） （P＝0.015）， and the successful detoxification rate in the population with Zhongshan local registered residence was significantly higher than that in those with non-local registered residence （P＜0.001）. CONCLUSIONS Age， registered residence status， age at first drug use， and duration of drug abuse are key influencing factors for successful detoxification in patients undergoing methadone maintenance therapy， and the last methadone dose may be associated with successful detoxification.

Objective To analyze the clinical distribution,drug resistance characteristics,molecular prevalence,and impact of immunocompromised status on the infection rate of carbapenem-resistant Enterobacteriaceae(CRE)isolated from pediatric respiratory tract samples(sputum,bronchoalveolar lavage fluid).Methods A retrospective analysis was conducted on clinical data of hospitalized children from 2019 to 2023.A total of 1 235 non-repetitive strains of Enterobacteriaceae bacteria were obtained from pediactric respiratory tract samples.Drug susceptibility testing,multilocus sequencing typing(MLST),and resistance-related gene sequencing were performed on 100 isolated CRE strains,to study the clinical distribution,drug resistance characteristics,and molecular prevalence of CRE,and to further analyze the impact of immunocompromised status on the respiratory CRE infection rate in children.Results From 2019 to 2023,the detection rate of CRE in 1 235 strains of Enterobacteriaceae bacteria was 8.10%(100/1 235).Among them,51.0%(51/100)of CRE were isolated from the intensive care unit(ICU),of which 33.0%(33/100)were isolated from the Surgical ICU,18.0%(18/100)of CRE was isolated from the Medical ICU;32.0%(32/100)of CRE were isolated from Department of Neonatology,with the majority(74.0%)isolated from infants under 6 months of age.Of all pediatric patients,85.0%recovered and were discharged after treatment.Immunocompromised status was identified as an independent risk factor for CRE infection.Among 100 strains of CRE,Carbapenem-resistant Klebsiella pneumoniae(CRKP)was the most commonly detected strain,accounting for 88.0%(88/100),followed by Escherichia coli at 6.0%(6/100)and Enterobacter cloacae at 4.0%(4/100).CRE strains were highly resistant to carbapenems and cephalosporins,with prevalent resistance to amikacin,ciprofloxacin,and levofloxacin.However,their resistance rates were relatively low to tigecycline,colistin,minocycline,ceftazidime/avibactam,meropenem/vaborbactam,and imipenem/relebactam.The screening results of carbapenem resistance genes showed that blaKPC-2 was the most prevalent gene(74.0%),followed by blaNDM-1(14.0%)and blaNDM-5(11.0%).Molecular typing showed that ST11 type CRE was the dominant type,comprising 72.0%(72/100)and was the primary epidemic clone.Conclusions CRKP is the most prevalent CRE strain isolated from pediatric respiratory tract samples,primarily identified in the ICU,Department of Neonatology,and among infants under 6 months of age.Immunocompromised status is an independent risk factor for respiratory CRE infection in children.CRE generally has high resistance to antibacterial drugs,with blaKPC-2 being the dominant resistance genotype,and ST11 as the predominant multilocus sequence type.Clinical management should account for these characteristics to implement timely interventions and rational therapeutic strategies.

Objective:To analyze the correlation between serum uric acid-to-high-density lipoprotein cholesterol ratio (UHR) and risk of all-cause death or cardiovascular disease (CVD) death among urban and rural elderly in Beijing.Methods:Based on the Beijing Healthy Aging Cohort Study, 9 022 participants with complete baseline data were enrolled, and their survival and death outcomes were followed up. Multivariable Cox proportional hazard regression model were used to analyze the associations between the UHR level and the risks of all-cause mortality and CVD mortality.Results:As of March 31, 2021, the median follow-up time M( Q1, Q3) was 6.18 (5.36, 6.75) years. There were 1 166 all-deaths, with a death density of 19.26 per 1 000 person-years, and 562 CVD deaths, with a death density of 9.28 per 1 000 person-years. After adjusting sociodemographic characteristics and lifestyle factors, multivariable Cox proportional hazard regression model showed that the risk of all-cause mortality increased by 3% ( HR=1.03, 95% CI: 1.02-1.04) and the risk of CVD mortality increased by 4% ( HR=1.04, 95% CI: 1.02-1.06) for every 1% increase in UHR. Compared with the T1 group of UHR tertiles, the T3 group had a 42% increase in the risk of all-cause death ( HR=1.42, 95% CI: 1.22-1.66) and a 53% increase in the risk of CVD death ( HR=1.53, 95% CI: 1.21-1.94). Conclusions:The UHR level is significantly associated with the risks of all-cause mortality and CVD mortality among urban and rural older adults in Beijing. The UHR level may be one of the potential predictors of death risk in community-dwelling older adults.

Objective To analyze the risk factors of ultrasound-guided percutaneous transluminal angioplasty(PTA)for treating thrombotic occlusion of autogenous arteriovenous fistula(AVF).Methods A total of 144 patients with thrombotic occlusion of autologous AVF were retrospectively enrolled and divided into success group(n=114)and failure group(n=30)according to the success of treatment or not.Clinical data and ultrasonic parameters of AVF were compared between groups.A multivariate logistic regression model was constructed to analyze the risk factors of PTA for treating thrombotic occlusion of autologous AVF,and the results were visualized by nomogram.Then receiver operating characteristic curve was drawn,and the area under the curve(AUC)was calculated to evaluate the predictive efficacy of this model.Results Patients'age,use years of AVF,degree of vascular calcification,the mean Young modulus(Emean),the maximum Young modulus(Emax)and the minimum Young modulus(Emin)were all higher,while the number of venous outflow tracts of AVF was less in failure group than those in success group(all P＜0.05).Moderate to severe calcification of vascular,high Emean of thrombus and 1 venous outflow tract of in AVF were all independent risk factors of ultrasound-guided PTA for treating thrombotic occlusion of autologous AVF(all P＜0.05),and AUC of the obtained model for predicting failure of treatment was 0.969.Conclusion Moderate to severe calcification of vascular,high Emean of thrombus and 1 venous outflow tract of AVF were all independent risk factors of ultrasound-guided PTA for treating thrombotic occlusion of autologous AVF.

Objective:To analyze the drug resistance status of Mycobacterium tuberculosis（MTB）at a hospital in Xiamen over the past decade. Methods:Sputum culture-positive specimens of tuberculosis patients from Xiamen Xinglin Hospital from 2015 to 2024 were collected retrospectively. Isolates were identified as MTB complex and subjected to drug susceptibility testing. Drug resistance patterns and trends over the study period were analyzed using descriptive statistics and Chi-square trend tests in SPSS 27.0 and GraphPad Prism 8.0.Results:Among 3 883 MTB isolates analyzed，1 132（29.15%）exhibited resistance to at least one drug. The highest rates of resistance to individual first-line drugs were observed for isoniazid（INH，16.04%），streptomycin（SM，15.43%），and rifampicin（RFP，12.28%）. Multidrug-resistant tuberculosis（MDR-TB）was identified in 380 isolates（9.79%）. The predominant MDR resistance patterns were INH+RFP+SM（2.34%），INH+RFP（1.65%），and INH+RFP+SM+ethambutol（EMB）（1.03%）. Polyresistance was found in 188 isolates（4.84%），the predominant patterns were INH+SM（1.49%），INH+fluoroquinolone（FQs）（0.31%），and INH+para-aminosalicylic acid（PAS）（0.31%）. Extensively drug-resistant tuberculosis（XDR-TB）was detected in 49 isolates（1.26%）. From 2015 to 2024，significant decreasing trends were observed for overall drug resistance（ χ2=8.858， P=0.003），MDR（ χ2=15.692， P<0.001），and RFP resistance（ χ2=21.627， P<0.001）. In contrast，fluoroquinolone（FQs）resistance showed no significant trend（ χ2=0.149， P=0.699）. Among RFP resistant and MDR isolates，FQs resistance rates were notably high at 33.12%（158/477）and 36.84%（140/380），respectively. Conclusions:The MTB resistance situation in the hospital has gradually declined in the past 10 years，but the resistance situation remains severe，and clinical attention needs to be strengthened on the use of FQs.

Expert consensus, as an important supplement to clinical practice guidelines, supports clinical decision-making when evidence is lacking or controversial. Compared to clinical practice guidelines, the presentation of expert consensus is more diverse. Currently, there are no reporting guidelines for expert consensus in clinical and public health decision-making. The RIGHT (Reporting Items for Practice Guidelines in Healthcare) checklist is the most commonly used international guideline reporting standard, and is often referred to when writing expert consensus. However, the RIGHT checklist does not include a section on consensus formation methods; while the ACCORD (ACcurate COnsensus Reporting Document) checklist includes reporting requirements for consensus formation methods, but not for reporting recommendations. Therefore, this article integrates the RIGHT and ACCORD reporting checklists and proposes an integrated reporting framework (TIMER-DO) to help authors combine these two commonly used international reporting standards and complete the standardized reporting of expert consensus.

Objective:To compare minimally invasive surgery with traditional open surgery, analyze the current application status of health economic evaluations in the treatment of digestive tract cancers, such as esophageal cancer, gastric cancer, and colorectal cancer by minimally invasive surgery and provide evidence for the rational selection of clinical treatment, alleviation of disease-related economic burdens, and rational allocation of healthcare resources.Methods:By using five databases, i.e. China National Knowledge Infrastructure, Wanfang data, Chinese Biomedical Literature Database, PubMed, and Embase, a database was established to retrieve all the papers about health economic studies of minimally invasive surgery for esophageal cancer, gastric cancer, and colorectal cancer published until December 31, 2023. Literature was analyzed by using software NoteExpress 3.8, and data were processed using Excel 2021. The quality of included papers was evaluated using the CHEERS 2022 checklist, and Meta-analysis was conducted by using software Stata 17.0.Results:A total of 10 919 relevant papers were retrieved, and 59 studies were included. Only 14 studies (23.7%) used standard health economic evaluation methods. Meta-analysis results revealed no significant differences in direct medical expenditure and total expenditure between minimally invasive surgery and open surgery. However, the expenditure for minimally invasive surgery exhibited a significant increase [mean difference ( MD)=5 973.12 yuan, P<0.001], while hospital stay and indirect expenditure significantly decreased ( MD: -4.85 days and -733.79 yuan, P<0.001). In China, for gastric cancer, the direct medical expenditure of endoscopic surgery was lower than that of open surgery ( MD=-33 000.00 yuan) with no significant difference ( P<0.001). In colorectal cancer cases, the direct medical and surgical expenditures for laparoscopic surgery were higher than those for open surgery ( MD: 4 277.94 yuan and 4 267.80 yuan, P<0.001), while the indirect and total medical expenditures decreased ( MD: -768.34 yuan and -159.10 yuan). Hospital stays in patients who had minimally invasive surgery for all three types of cancer were shorter than those who had open surgery ( P<0.001). Conclusions:In the treatment of gastrointestinal cancer, compared with open surgery, minimally invasive surgery shows higher expenditure, but has advantages, such as shorter hospital stay and lower indirect expenditure, and there were no significant differences in direct medical and total expenditures between the two approaches. When conducting health economic evaluation, factors such as postoperative complications, hospital stay, and patient's economic status should be considered for their impact on total medical expenditure. It is necessary to pay attention to the application of health economic evaluations in healthcare decision-making.
