ABSTRACT
Objective: To development the prognostic nomogram for malignant pleural mesothelioma (MPM). Methods: Two hundred and ten patients pathologically confirmed as MPM were enrolled in this retrospective study from 2007 to 2020 in the People's Hospital of Chuxiong Yi Autonomous Prefecture, the First and Third Affiliated Hospital of Kunming Medical University, and divided into training (n=112) and test (n=98) sets according to the admission time. The observation factors included demography, symptoms, history, clinical score and stage, blood cell and biochemistry, tumor markers, pathology and treatment. The Cox proportional risk model was used to analyze the prognostic factors of 112 patients in the training set. According to the results of multivariate Cox regression analysis, the prognostic prediction nomogram was established. C-Index and calibration curve were used to evaluate the model's discrimination and consistency in raining and test sets, respectively. Patients were stratified according to the median risk score of nomogram in the training set. Log rank test was performed to compare the survival differences between the high and low risk groups in the two sets. Results: The median overall survival (OS) of 210 MPM patients was 384 days (IQR=472 days), and the 6-month, 1-year, 2-year, and 3-year survival rates were 75.7%, 52.6%, 19.7%, and 13.0%, respectively. Cox multivariate regression analysis showed that residence (HR=2.127, 95% CI: 1.154-3.920), serum albumin (HR=1.583, 95% CI: 1.017-2.464), clinical stage (stage Ⅳ: HR=3.073, 95% CI: 1.366-6.910) and the chemotherapy (HR=0.476, 95% CI: 0.292-0.777) were independent prognostic factors for MPM patients. The C-index of the nomogram established based on the results of Cox multivariate regression analysis in the training and test sets were 0.662 and 0.613, respectively. Calibration curves for both the training and test sets showed moderate consistency between the predicted and actual survival probabilities of MPM patients at 6 months, 1 year, and 2 years. The low-risk group had better outcomes than the high-risk group in both training (P=0.001) and test (P=0.003) sets. Conclusion: The survival prediction nomogram established based on routine clinical indicators of MPM patients provides a reliable tool for prognostic prediction and risk stratification.

Objective: To explore the correlation between club drug use and anal canal human papillomavirus (HPV) infection in HIV-negative and HIV-positive men who have sex with men (MSM) in Taizhou. Methods: A cross-sectional survey was conducted in Taizhou. HIV-negative MSM were recruited by convenient sampling in voluntary counseling and testing clinics of Taizhou prefectural CDC from August 2016 to October 2017, and HIV-positive MSM were recruited through the routine follow-up and management by Taizhou prefectural CDC from August 2016 to June 2019. A face-to-face questionnaire interview was conducted to collect the information about the socio-demographic characteristics, sexual orientation, sexual behavior, club drug use and other information of the participants. Anal canal swabs were collected for HPV genotyping. The correlation between club drug use and the prevalence of HPV infection were evaluated with χ2 test and logistic regression analysis. Results: A total of 69 HIV-negative and 345 HIV-infected MSM were included. The prevalence of any type of anal canal HPV infection in HIV-negative MSM (27.5%, 19/69) was lower than that in HIV-positive MSM (66.4%, 229/345) (χ2=36.114,P<0.001). The prevalence of self-reported club drug use in HIV-negative MSM was higher (17.4%, 12/69) than that in HIV-positive MSM (7.0%, 24/345) (χ2=7.886, P=0.005). For HIV-negative MSM, the prevalence of club drug use was higher in MSM who had homosexual group sex (P=0.036); the prevalence of HPV infection was 50.0% (6/12) in club drug users and 22.8% (13/57) in non-club drug users (χ2=3.674, P=0.055). For HIV-positive MSM, the prevalence of HPV infection was 70.8% (17/24) in club drug users and 66.0% (212/321) in non-club drug users (χ2=0.230, P=0.632). Multivariable logistic regression model showed that HPV infection in MSM was positively correlated with HIV infection (OR=5.42, 95%CI: 2.92-10.06), and the association between HPV infection and club drug use (OR=1.66, 95%CI: 0.75-3.71) was not significant. Conclusions: HIV infection was positively correlated with anal canal HPV infection in MSM in Taizhou. Club drug use was positively correlated with high-risk sexual behaviors, while its association with HPV infection needs further study.

ABSTRACT
ObjectiveTo understand the infection of AIDS， syphilis， and gonorrhea in men who have sex with men （MSM）， and the factors influencing the acceptance of gonorrhea testing in Dehong Dai Jingpo Autonomous Prefecture （Dehong Prefecture）， Yunnan Province. MethodsAcross-sectional survey was conducted to describe and analyze the acceptance of AIDS， syphilis， and gonorrhea testing among MSM tracked in Dehong Prefecture in 2018. ResultsA total of 385 MSM were included in the analysis， with a 100.0% HIV and syphilis testing rate. The HIV antibody positivity rate was 10.6% （41/385） and the positivity rate of syphilis antibody was 14.8%（57/385）. Only 30.4% of the subjects were willing to test for gonorrhea， and 13.7%（16/117）of them were test positive. Further multifactorial analysis revealed that local MSM and syphilis co-infected individuals were more likely to be tested for gonorrhea （aOR=2.48， 95%CI=1.33-4.65， P=0.004； aOR=2.59， 95%CI=1.43-4.71， P=0.002）. ConclusionThe positive rates of AIDS， syphilis and gonorrhea in MSM population in Dehong Prefecture are relatively high. Integrated interventions of STD/AIDS and gonorrhoea detection should be strengthened.

ABSTRACT
Objective:To examine the survival status and explore factors related to death among human immunodeficiency virus （HIV） infected patients receiving antiretroviral therapy （ART） in Taizhou City during 2006‒2019. Methods:A retrospective cohort study was conducted to analyze the data on HIV-infected patients receiving ART in Taizhou during 2006‒2019. Kaplan-Meier （K-M） method was used to calculate the cumulative survival rate and cumulative treatment success rate. Cox regression model was used to determine survival status and factors associated with ART. Results:A total of 2 904 HIV-infected patients was included. The cumulative survival rate after 1， 3， 5， and 8 years of ART were 96.9%， 94.9%， 93.1% and 92.1%， respectively， and the cumulative treatment response rate were 91.3%， 85.3%， 81.8% and 73.8%， respectively. Compared with aged 18-30 years old， baseline CD4+T cell >350 count/μL， normal hemoglobin level， effective ART， no clinical symptom at baseline， and homosexual transmission， we found that aged 51-60 years old（HR=4.94，95%CI：1.66-14.69）， aged over 60 years old（HR=9.14，95%CI：3.14-26.63）， anemia at baseline（HR=2.24，95%CI：1.55-3.23）， baseline CD4+T cell <200 count/μL（HR=4.35，95%CI：2.14-8.86）， ART failure （HR=3.90，95%CI：2.73-5.58）， heterosexual transmission（HR=1.92，95%CI：1.15-3.20）， and signs of symptom at baseline（HR=1.68，95%CI：1.16-2.41） were risk factors of HIV-related death. Conclusion:The effect of ART in Taizhou City is confirmed with a high cumulative survival rate and treatment success. We should pay additional attention to senior HIV-infected patients with anemia at baseline and intensively monitor the effect of ART. Interventions such as “treat after discover” are supposed to be implemented more widely to further reduce HIV-related mortality.
ABSTRACT
Objective To investigate the accessibility of HIV-related public health services among cross-border couples living in Dehong Prefecture and age differences. Methods A cross-sectional survey was conducted among cross-border couples in Dehong Prefecture from January 2017 to July 2019. Results In total, 32 182 participants were included. The proportion of people who had received HIV testing services, HIV-related intervention services in past year, care and help in the past year, and participated in new rural cooperative medical services (NCMS) were 57.8%, 92.7%, 6.5% and 94.5%, respectively; and the latter three services were significantly different across age groups (P<0.001). In multivariable Logistic regression model, variables significantly associated with having ever received HIV testing services older age (51-85 years: OR=0.71, 95% CI: 0.63-0.81), women (OR=1.14, 95% CI:1.03-1.25), county/city (Longchuan: OR=6.30, 95% CI: 5.72-6.93; Lianghe: OR=1.27, 95% CI: 1.11-1.44; Yingjiang: OR=0.88, 95% CI: 0.82-0.94), Dai ethnic minority (OR=1.60, 95% CI: 1.50-1.72), marriage registration (marriage registration for border inhabitants: OR=0.60, 95% CI: 0.56-0.65; non-registration: OR=0.66, 95% CI: 0.62-0.70), years of marriage (4-5 years: OR=1.21, 95% CI: 1.12-1.31; 6-60 years: OR=1.30, 95%CI:1.22-1.39), having not received care and help in the past year (OR=0.64, 95% CI: 0.58-0.71) and having not participated in NCMS (OR=0.58, 95% CI: 0.52-0.65). Conclusions The accessibility to HIV-related public health services are relatively high among cross-border couples in Dehong Prefecture. However, the relatively low proportion of receiving AIDS testing services, particularly among certain groups and counties/cities, need to be strengthened.
ABSTRACT
Objective To investigate characteristics and influencing factors of heterosexual behavior among young men who have sex with men (YMSM) in Taizhou, and to provide evidence for conducting intervention on acquired immune deficiency syndrome (AIDS). Methods The demographic characteristics, behavioral characteristics and AIDS related knowledge of YMSM in Taizhou were investigated by the method of questionnaire survey from January to July in 2015, February to September in 2016, January to August in 2017, and January to August in 2018. Human immunodeficiency virus (HIV), syphilis and hepatitis C virus (HCV) were tested in everyone. Results A total of 432 YMSM were recruited, including 56 YMSM who had heterosexual behavior. 14.3% of YMSM who had heterosexual behavior never used condoms when having heterosexual behavior. 26.8% did not use condoms when having the last heterosexual behavior. The detection rates of HIV and syphilis were both 5.4%. No HCV positive person was found. The awareness rate of AIDS related knowledge was 91.1%. In multivariate logistic regression, marital status and local residence time were influencing factors of heterosexual behavior among YMSM. Conclusions YMSM in Taizhou are at risk of spreading HIV and syphilis. Although the awareness rate of AIDS related knowledge is better, there are still high-risk behavior such as commercial sex behavior and knowledge-practice separation such as not using condoms. It is necessary to promote intervention activities for safe sexual behavior, especially among YMSM who are married and live in the local areas for less than 2 years.
ABSTRACT
Objective To understand the prevalence of HIV infection and its influencing factors in the premarital physical examination population in Dehong Prefecture, Yunnan Province, 2017. Methods The data of people receiving premarital medical examination was collected, the demographic characteristics was described and the related factors was analyzed by Logistic regression. Results There were 21 875 participants receiving premarital medical examination in Dehong. 98(0.45%) participants were confirmed positive for HIV and male infection rate was 0.47% (52/10 955) and female was 0.42% (46/10 920). Among the 98 patients, 20 patients were infected in the first time, and main route was sexual transmission accounting for 81.63% (80/98). Logistic multivariate regression analysis showed that age, ethnicity and drug use were the influencing factors for premarital couples infecting HIV. The risk of HIV infection in 31-40 and 41-50 years old group was higher than the people under 25 years old group(OR=3.78, 95% CI：1.81-7.89, P<0.001；OR=3.95, 95% CI：1.72-9.08, P=0.001). The infection risk of Dai and Jingpo ethnic group was higher than that of the Han ethnic(OR=1.86, 95% CI：1.06-3.29, P=0.031；OR=3.25, 95% CI：1.81-5.84, P<0.001). The risk of infection among drug users was much higher than non-drug users (OR=926.76, 95% CI：271.65-3 161.71, P<0.001). Conclusion Age, ethnicity, and drug use are influencing factors of HIV infection among premarital couples. Targeted measures need to be taken against risk factors. HIV infection is mainly transmitted by sexual transmission. It can be effectively detected and controlled through premarital medical examination.
ABSTRACT
Objective To investigate the characteristics of methadone maintenance treatment(MMT)clients, and to explore their retention rate and associated factors in Taizhou, Zhejiang Province. Methods Heroin or opiate addicts who started MMT between 2006 and 2014 in study area were included. Data including demographics, history of drug use and treatment information was extracted from the National MMT Data Management System and descriptive analysis were conducted. Multiple logistic regression models were used to explore factors associated with retention rate. Results In total, 2 262 MMT clients were included for analysis. Most of them were male(87.53%), single, divorced or widowed(55.75%), and had an education of junior middle school or below(88.68%). Almost all of them (98.32%)were heroin addicts, and the age at first drug use ranged from 9 years to 54 years, with average age of(25.06±6.34)years. A total of 1 123(49.65%)clients had a history of inject drug use and 81(3.58%)clients had ever shared needles with others. The average duration on MMT was 5.02±2.01 years, and the average methadone dosage during treatment was (34.49 ±22.69)mL. The MMT retention rate was 29.2% (661/2 262). In multivariable analysis, districts such as Huangyan District, Yuhuan County and Linhai City, aged≥40 years and average methadone dosage>20 mL during treatment were independently and positively associated with retention rate. Conclusion Most of MMT clients in Taizhou are male, unmarried, and had low education level. The retention rate is low in Taizhou but older patents and those receive high methadone dosage have a relatively higher retention rate.
ABSTRACT
Objective To determine the survival rate of HIV/AIDS patients after receiving free antiretroviral treatment in Dehong prefecture, Yunnan province. Methods A retrospective cohort analysis was conducted on all the HIV/AIDS patients aged over 16 years who had started antiretroviral treatment during January 2007 throughout December 2009 in Dehong prefecture.Results A total of 3103 HIV/AIDS patients had received antiretroviral treatment during the study period. Among them, the mean age was (36.0 ± 9.9) years and 62.4% were males. 66.2% of them were infected with HIV through heterosexual transmission, and the mean treatment follow-up time was 21.7 months. Most patients well complied with the treatment, i.e., the average times of not taking the medicine were less than 5 per month. The cumulative survival rate of antiretroviral treatment after 1, 2, 3, 4, and 5 years were 0.95, 0.94, 0.93, 0.92, and 0.92, respectively. Data from the Cox proportional hazard regression model analysis indicated that, after adjustment for age, gender, and marital status, the baseline CD4+T cell counts and transmission route could significantly predicate the rates of survival. Those who were with baseline CD4+T cell counts as 200-350/mm3 were less likely to die of AIDS than those with CD4+T cell counts ＜200/mm3 (Hazard Ratio or HR=0.16, 95%CI:0.09-0.28), and HIV-infected through mother-to-child transmission or routes other than heterosexual transmission were less likely to die of AIDS than through injecting drug use (HR=0.35, 95% CI:0.13-1.00). Conclusion Free antiretroviral treatment had significantly improved the survival of HIV/AIDS patients. Earlier initiation of antiretroviral treatment was likely to have achieved better survival effects.
ABSTRACT
Objective To assess the adherence,immunologic and survival responses in HIV-infected patients receiving free antiretroviral therapy (ART). Methods All adult HIV-infected patients in Wenxi county who started antiretroviral treatment (ART) between 01 July 2001 and 31 December 2006 and aged above 18 years were included in this study. Epidemiological survey and laboratory tests were performed before,0.5 months after, 1 months after, 2 months after and every 3 months after initiation of ART to recognize the adherence, efficacy (CD4+ T cell counts) and survival to the regimens. Results The median follow-up time period was 16.5 months (Interquartile: 15.5-20.8 months). At baseline, the median of CD4+ T cell counts were 154 cells/μl (Interquartile: 81-212 cells/μl). Treatment was effective in most of the patients, the CD4+ T cell count of patients increased after the initiation of ART. The maximum increase was recorded at month 3, from the median of 154 cells/μl to 220 cells/μl (P<0.001) ,and thereafter the count remained stable. When comparing with patients with baseline CD4+ T cell count≥100 cells/μl, those with baseline CD4+ T cell count < 100 cells/μl showed a higher mean increase in the first three months of treatment. The cumulative probability rates of remaining alive were 0.94,0.88 and 0.87 at 3,12,24 months, respectively. In multivariate Cox's proportional hazard models, after adjustment for the type ofinitial regimens (NVP vs. EFV/IDV), CD4+T cell count of less than 50 cells/μl (vs. 50 cells/μl or more) was strongly associated with death hazard ratio 0.21 (95% CI:0.06-0.68). Conclusion Our data showed that ART was effective for improving immunologic response of adult patients with HIV/AIDS. CD4+ T cell count at initiation was associated with survival time in patients starting ART,suggesting that monitoring of CD4+ T count should be strengthened to early initiate antiretroviral therapy for HIV-infected patients.
