RESUMEN
Objective:To determine the prevalence of AIDS/HIV， sexual behavior， knowledge， and access to HIV-related services among college students in Taizhou from 2016 through 2018， and provide scientific evidence for developing targeted strategies and measures. Methods:Based on the National HIV/AIDS Sentinel Surveillance， a cross-sectional survey was conducted annually among college students in three sentinels by a multi-stage cluster sampling across Taizhou， using questionnaire and laboratory examination. Results:A total of 4 185 college students were surveyed during 2016–2018， in which the proportion of reporting sexual behavior was 7.7%， with 58.4% using condom at. Sexual behavior， with fixed sexual partners， casual partners， commercial partners， and homosexual partners accounted for 68.7%， 23%， 4.0%， and 4.0%， respectively. Sexual experience and sexual behavior with fixed partners were statistically different among colleges and gender， which was much higher in male and vocational schools. The awareness rate of HIV/AIDS knowledge was 65.8%； 3.6% was found to have HIV voluntary counseling and testing， in which 7.8% had sexual behavior， indicating an upward trend over years. No college student tested positive for HIV from 2016 to 2018， and only one tested positive for anti-syphilis antibody and one positive for anti-hepatitis C antibody. Conclusions:Young male and vocational students in Taizhou are likely to have more sexual behavior and lower awareness on HIV/AIDS. College students have at-risk sexual behavior， insufficient awareness of HIV/AIDS， which may facilitate high risk of infection. It warrants further strengthening HIV/AIDS health education.
RESUMEN
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.
RESUMEN
Objective To compare the risk for HIV, syphilis and HCV infection between club drug users and traditional drug users in Taizhou City of Zhejiang Province, in order to provide evidence for further behavioral intervention. Methods Drug users in Taizhou were surveyed with the questionnaires for national HIV sentinel surveillance during 2016-2019.Blood samples were collected for detection of HIV, syphilis and HCV antibodies. Results A total of 1 612 drug users were surveyed, in which club drug users accounted for 78.7% and traditional drug users 21.3%.Significant differences were observed in gender, age, educational level, ethnic background, and household registration between these two groups (P < 0.05).Among club drug users, injecting drug users accounted for 7.1%, lower than traditional drug users (P < 0.001).Among the injecting drug users, those who shared needles with others accounted for 8.9%, similar to the traditional drug users (P>0.05).In the past year, the proportion of having sex after drug abuse among club drug users was 77.9%, higher than traditional drug users (P=0.002).The proportion of condom use during sex were nearly 30.0% for both club drug users and traditional drug users.Of the club drug users, 0.2% were infected with HIV, which was not significantly different from that in traditional drug users (P>0.05).The prevalence of syphilis among club drug users was 12.6%, higher than traditional drug users (P < 0.05);whereas the HCV prevalence (10.4%) was lower among club drug users (P < 0.001). Conclusion The threats of blood-borne transmission and sexual transmission of diseases are common among club drug users, suggesting the need of targeted intervention measures.
RESUMEN
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.
RESUMEN
Objective To investigate the value of radiofrequency catheter ablation(RFCA) on idiopathic ventricular tachycardia(IVT) in children.Methods The treatment efficiency of 35 patients accepting RFCA from March 2000 to February 2006 was analyzed,which was divided into control group and study group,randomly.The target site of IVT was localized by routine mapping in control group,and study group was localized by routine mapping combining doppler tissue imaging(DTI) on the basic treatment.Results Numbers of discharge,X-ray exposure time in study group were shorter than that in control group.There were no significance of radiofrequency energy,achievement rates and relapse rates between two groups.Conclusions RFCA is a safe and effective method on IVT.Children are localized combined with DTI shall decrease numbers of discharge and X-ray exposure time.
