Objective:To explore the risk factors of quality of life(QoL)being below normal levels in patients undergo-ing total knee arthroplasty(TKA)at 6 months after surgery,and to construct a nomogram prediction model.Method:Two-hundred and sixty-seven patients who underwent TKA at Qingdao Hospital,University of Health and Rehabilitation Sciences(Qingdao Municipal Hospital)from April 2021 to October 2022 were selected.Clini-cal data were collected on admission and within 6 months after surgery.According to the QoL assessment at 6 months after surgery,they were divided into a high-quality group(n=136)and a non-high-quality group(n=131).LASSO regression was used to screen the predictors,and multivariate Logistic regression was established to construct the predictive model of QoL of TKA patients at 6 months after surgery.Receiver operating character-istic curve(ROC curve),calibration curve and decision curve were drawn to evaluate its predictive value.Result:A total of 131(49.06%)patients had lower QoL than normal 6 months after TKA.LASSO regression selected age,surgical side,education level,duration of knee osteoarthritis(KOA),perioperative recovery,and visual analog scale(VAS)during preoperative rest as predictors.Multivariate logistic regression analysis showed that age(OR,1.08;95%CI,1.01-1.15),duration of KOA(OR,1.13;95%CI,1.05-1.22),VAS during preoperative rest(OR,1.94;95%CI,1.20-3.15),and perioperative rehabilitation(OR,0.42;95%CI,0.18-0.97)were independent risk factors for lower than normal QoL in TKA patients at 6 months after surgery(P<0.05).Statistically significant indicators in multivariate logistic regression analysis were includ-ed in the nomogram model,which underwent internal validation.The area under the ROC curve was 0.829(95%CI,0.779-0.879),indicating good predictive ability of the model.The calibration curve showed good consistency between the predicted probability and the actual probability.The decision curve analysis showed that this model is clinically applicable.Conclusion:Age,duration of KOA,VAS during preoperative rest,and perioperative rehabilitation are indepen-dent predictors of lower-than-normal QoL in TKA patients at 6 months after surgery,and the nomogram mod-el based on the above indicators had good predictive performance.

Objective:To describe the prevalence of non-alcoholic fatty liver disease (NAFLD) in people living with HIV in Taizhou, Zhejiang Province, and identify the factors associated with NAFLD in this population.Methods:A cross-sectional survey was conducted from 2021 to 2023. Based on the routine follow-up management of people living with HIV, liver ultrasound examination, physical examination and laboratory test were conducted to collect the information about the diagnosis of NAFLD and biochemical indicators in this population. Logistic regression model was used to identify the factors associated with the prevalence of NAFLD.Results:In the 2 550 study participants, the prevalence of NAFLD was 21.5% (548/2 550), abnormal liver function was found in 23.7% (604/2 550) of the study participants, and liver fibrosis was found in 45.2% (1 152/2 550) of the study participants. Multivariable logistic regression analyses showed that being women (a OR=0.55, 95% CI: 0.42-0.73), being overweight or obese (a OR=3.22, 95% CI: 2.59-4.01), having diabetes (a OR=3.37, 95% CI: 2.15-5.29), having dyslipidemia (a OR=2.96, 95% CI: 2.25-3.89), CD4 + T lymphocyte (CD4) counts <200 cells/μl (a OR=0.61, 95% CI: 0.42-0.88), and receiving Efavirenz (EFV) + Lamivudine (3TC) + Zidovudine (AZT) for antiretroviral therapy (ART)(a OR=1.52, 95% CI: 1.17-1.98) were associated with NAFLD. NAFLD was positively associated with abnormal liver function (a OR=2.01, 95% CI: 1.60-2.52) and inversely associated with liver fibrosis (a OR=0.76, 95% CI: 0.59-0.98). The 45-59 age group (a OR=7.05, 95% CI: 5.65-8.80), CD4 counts <200 cells/μl (a OR=1.45, 95% CI: 1.06-1.97) and receiving Nevirapine (NVP)+3TC+AZT of ART (a OR=1.87,95% CI: 1.44-2.43) were the main factors associated with liver fibrosis. Conclusions:The prevalence of NAFLD in people living with HIV Taizhou was more than 20.0%, with a significant proportion of them having abnormal liver function and liver fibrosis. Being overweight or obese, suffering from diabetes, having dyslipidemia, low CD4 counts, and receiving specific ART were associated with NAFLD. NAFLD, CD4 counts and specific ART were the main factors associated with abnormal liver function and liver fibrosis.

Objective:To understand the prevalence of major chronic diseases of diabetes, cardiovascular disease and malignant tumor in people living with HIV in Taizhou.Methods:The data were collected from China Information System for Disease Control and Prevention and Taizhou Chronic Disease Information Management System. A total of 5 126 people living HIV under follow-up in Taizhou from 1998 to 2022 were included in the analysis. Software SAS 9.4 was used for χ 2 test, trend analysis and logistic regression analysis. Results:In the 5 126 people living with HIV, the reported prevalence rates of diabetes,cardiovascular disease and malignant tumor were 10.28% (527/5 126),3.98% (204/5 126) and 6.01% (308/5 126), respectively. 37.00% (195/527) and 48.58% (256/527), 40.20% (82/204) and 48.53% (99/204), 37.66% (116/308) and 48.38% (149/308) were diagnosed as diabetes, cardiovascular disease and malignant tumor before and after confirmation of HIV infection. From 2013 to 2022, the proportion of HIV infected people diagnosed with diabetes, cardiovascular disease and malignant tumor after confirmation increased (trend χ2=79.98, P<0.001; trend χ2=17.44, P<0.001; trend χ2=32.06, P<0.001). Based on the analysis on the factors for complicated chronic diseases in people living with HIV, it was found that women under 60 years old (a OR=0.66, 95% CI: 0.50-0.86) and those with access to antiviral treatment for >5 years before 2016 (a OR=0.54,95% CI:0.37-0.78) were less likely to develop complicated chronic diseases, and those under 60 years old with initial CD4 +T lymphocytes counts <200 cells/μl (a OR=1.32, 95% CI: 1.02-1.70), those aged 40-49 and 50-59 years (a OR=2.88, 95% CI:2.20-3.79; a OR=5.43, 95% CI: 4.10-7.21) as well as those without a record of treatment medication use after 2016 (a OR=1.95,95% CI:1.20-3.16) were more likely to develop complicated chronic diseases. The probability of developing complicated chronic diseases might increase with age in people living with HIV. Conclusions:From 1998 to 2022, there was a certain proportion of complicated chronic diseases among HIV infected individuals in Taizhou, and the proportion of diagnosed cases increased after HIV infection was confirmed. It is necessary to conduct early chronic disease screening, behavior intervention and standardized management in people living with HIV.

Objective:To retrieve, evaluate, and integrate the best evidence of general anesthesia health education for adult patients undergoing elective surgery, so as to provide a basis for clinical health education guidance.Methods:Evidence-based questions were established based on the population, intervention, professional, outcome, setting and type of evidence (PIPOST) model. All evidence on general anesthesia health education for adult patients undergoing elective surgery were retrieved from databases or professional association websites such as Cochrane Library, British Medical Journal (BMJ) Best Practice, UpToDate, Agency for Healthcare Research and Quality, Guidelines International Network, National Institute for Health and Clinical Excellence, Clinical Guidelines Library, PubMed, China National Knowledge Infrastructure, WanFang Data, Medlive, American Society of Anesthesiologists, and Society of Anesthesiology of the Chinese Medical Association. The search period was from database establishment to June 18, 2023. Two researchers screened and evaluated the quality of the included literature, extracted and integrated the evidence to form the best evidence for general anesthesia health education in adult patients undergoing selective surgery.Results:A total of 10 articles were included, including four guidelines, three clinical decision-making, and three expert consensus. A total of 41 pieces of evidence on general anesthesia health education for adult patients undergoing elective surgery were extracted, including six aspects of anesthesia overview, pre-anesthesia evaluation, pre-anesthesia preparation, anesthesia process and cooperation, anesthesia recovery period management, and postoperative management.Conclusions:The best evidence of general anesthesia health education for adult patients undergoing selective surgery summarized can provide a basis for comprehensive and systematic education of anesthesia health educators.

Objective:To investigate the training effect of order-oriented medical students in Yunnan Province of China and related influencing factors and targeted suggestions, and to improve the training effect of order-oriented medical students in residency training bases in Yunnan Province.Methods:The stratified cluster sampling method was used to select 8 general residency training bases, and a questionnaire survey was performed among the 621 order-oriented students in these training bases. Finally, 616 valid questionnaires were collected. SPSS 26.0 was used to perform the two-sample rank sum test, the K-W test, and the ordered multinomial logistic regression analysis.Results:The training effect of the "5+3" order-oriented medical students in Yunnan Province was between generally good (48.29%) and good (45.37%). The effect of the provincial general training base is better than that of the municipal general training base, and most training students at the province level (167, 59.64%) thought that the training effect was good, while most of the training students at the prefecture or municipal level (194, 57.91%) thought that the training effect was generally good. When the teaching level of the teachers can meet the teaching work, the residential training effect of the order-oriented residential training students is well evaluated (197,68.17%). When skill training was carried out by the base at least once a month, most of the order-oriented trainees (96, 48.73%) thought that the training effect was good. The ordered multinomial logistic regression analysis showed that the nature of the base, sex, attitude towards policy, psychological state, teaching competency of teachers, perfection of the fund guarantee system, consistency of training plan with requirements, consistency of training process with requirements, and consistency of teaching activities with requirements were influencing factors for the training effect of "5+3" order-oriented medical students in residency training bases of Yunnan Province ( P<0.05). Conclusions:The training effect of "5+3" order-oriented medical students in residency training bases of Yunnan Province was between generally good and good. The training effect of bases can be improved by strengthening the construction of infrastructure, giving full play to the role of base linkage, perfecting the training plan, improving implementation and execution, building up a perfect fund guarantee system, enhancing the construction of general teaching team, emphasizing skill practice training, and implementing diversified training activities.

ObjectiveTo analyze the changes in HIV， syphilis and hepatitis C prevalence among men who have sex with men （MSM） in Taizhou City， Zhejiang Province from 2017 to 2022， and the utilization of HIV intervention services and its influencing factors. MethodsMSM participants were recruited from HIV sentinel surveillance in Taizhou through snowball sampling method. Participants’ socio-demographic characteristics， sexual behavior characteristics， knowledge of HIV and utilization of HIV intervention services were collected and statistically described by questionnaire survey. Blood samples from MSM sentinel population were also collected for HIV， syphilis， and HCV antibody testing. Multivariate logistic regression analysis was used to analyze the influencing factors for utilizing HIV intervention services among MSM. ResultsA total of 2 499 MSM were included in the analysis from 2017 to 2022， with HIV prevalence of 5.8%， syphilis prevalence of 4.0%， and HCV prevalence of 0.6%. The infection rate， proportion of homosexual anal sex and heterosexual sex showed a decreasing trend， while the proportion of condom use during homosexual anal sex， condom publicity and distribution， AIDS consultation and testing， acceptance of peer education， and online temporary homosexual sex showed an increasing trend. All these differences were statistically significant. Multivariate logistic regression analysis showed that COVID-19 epidemic （aOR=1.66， 95%CI：1.04‒2.64） and HIV knowledge awareness （aOR=2.57， 95%CI：1.22‒5.40） were positively correlated with increased acceptance of condom publicity and distribution， and utilization of AIDS counseling and testing. Those who sought male sexual partners through offline route （aOR=3.44， 95%CI： 1.16‒10.21）， and had a history of sexually transmitted diseases within one year （aOR=5.47， 95%CI： 1.04‒28.76） were positively correlated with community-based methadone maintenance therapy， clean needle provision and exchange services， while COVID-19 epidemic （aOR=0.35， 95%CI： 0.14‒0.88） was negatively correlated with the utilization of these services. COVID-19 epidemic （aOR=2.11， 95%CI： 1.54‒2.89）， HIV knowledge awareness （aOR=2.09， 95%CI： 1.08‒4.02）， offline search for male sexual partners （aOR=1.47， 95%CI： 1.03‒2.11）， and awareness of HIV infection of sexual partners （aOR=2.09， 95%CI： 1.62‒2.69） were positively correlated with the increased use of peer education service， while married or cohabited （aOR=0.73， 95%CI： 0.55‒0.98） and VCT （aOR=0.61， 95%CI： 0.46‒0.82） were negatively correlated with utilization of peer education service. ConclusionHIV infection rate of sentinel MSM population in Taizhou decreases， while the utilization of HIV intervention services increases in general. Targeted measures should be developed according to the changes in sexual behavior and HIV intervention services among MSM populations in Taizhou to improve the HIV intervention services for the MSM population.
