Changes of proportion regarding consistent condom use and syphilis infection among low-fee female sex workers aged 35 and above / 中华流行病学杂志

Objective To investigate the changes of proportion on both consistent condom use and syphilis infection among low-fee female sex workers aged 35 and above (LFSW),in order to provide evidence for targeted intervention strategies.Methods A total of six cities-Liuzhou city and Pingnan couty of Guigang city of Guangxi Zhuang Autonomous Region,Jinghong city of Xishuangbanna Dai autonomous prefecture and Dali city of Dali Bai autonomous prefecture of Yunnan province,Zhangjiajie city and Jianghua Yao autonomous county of Yongzhou city Hunan province were involved in this study,with 60 eligible participants needed in each city,estimated through a pre-study.The first cross-sectional survey was completed from October 2012 to January 2013.Face-to-face questionnaire interview was carried out to collect information on socio-demography,work-related information and condom use situation.Blood was collected for syphilis testing.The second cross-sectional survey was carried out from June to September,2015 under the same procedure.Results A total of 371 and 403 eligible participants were included in the first and second survey,respectively.When comparing the two surveys,we noticed that the average age showed a slight change,from 42.4 years to 43.8 years old (t=3.537,P＜0.001) and the average price for every commercial sex exchange increased from 36.8 RMB to 49.5 RMB (t=11.961,P＜0.001).In the first survey,46.9％ (174/371) of the participants had more than two years of experience working as LFSW,compared to 61.3％ (247/403) in the second survcy (x2=16.125,P＜0.001).Also,46.9％ (174/371) of the participants consistently used condoms with clients in the past month in the first survey versus 64.3％ (259/403) (x2=23.641,P＜0.001) in the second one.Rates of syphilis infection were found from 15.9％ (59/371) in the first survey reduced to 7.2％ (29/403) in the second survey (x2=14.533,P＜0.001).Conclusion Compared with the first survey,the proportion of consistent condoms use showed an increase.Although the proportion of syphilis infection decreased in the second survey,the scope did not meet the criteria on syphilis,set by the government.Targeted intervention strategies on condom promotion and syphilis control should be implemented consistently in this population.

<p><b>OBJECTIVE</b>To understood the accuracy of oral fluid-based rapid HIV self-testing among men who have sex with men (MSM) and related factors.</p><p><b>METHODS</b>Survey was conducted among MSM selected through non-probability sampling to evaluate the quality of their rapid HIV self-testing, and related information was analyzed.</p><p><b>RESULTS</b>The most MSM were aged 21-30 years (57.0%). Among them, 45.7% had educational level of college or above, 78.5% were unmarried, 59.3% were casual laborers. The overall accuracy rate of oral fluid based self-testing was 95.0%, the handling of"inserting test paper into tube as indicated by arrow on it"had the highest accuracy rate (98.0%), and the handling of"gently upsetting tube for 3 times"had lowest accuracy rate (65.0%); Chi-square analysis showed that educational level, no touch with middle part of test paper, whether reading the instruction carefully, whether understanding the instruction and inserting test paper into tube as indicated by the arrow on it were associated with the accuracy of oral fluid-based rapid HIV self-testing, (P<0.05). Multivariate logistic regression analysis indicated that educational level, no touch with middle part of test paper and understanding instructions were associated with the accuracy of oral fluid-based rapid HIV self-testing.</p><p><b>CONCLUSIONS</b>The accuracy of oral fluid-based rapid HIV self-testing was high among MSM, the accuracy varied with the educational level of the MSM.

Analysis of the risky behaviors among HIV positive female sex workers / 中华预防医学杂志

<p><b>OBJECTIVE</b>To analyze the characteristics of risky behaviors among different age groups of HIV positive female sex workers, and to explore the strengthening of their management.</p><p><b>METHODS</b>From January to June 2014, 22 814 female sex workers were investigated and tested HIV in 117 sentinel surveillance sites in Yunnan Province, and 181 were confirmed to be HIV antibody positive, who accepted questionnaire surveys. According to the age, the participants were divided into the < 35 years old age group and ≥ 35 years old age group. The demographic characteristics, knowledge about HIV/AIDS and related risk behaviors characteristics of the two groups were obtained via questionnaire surveys among 181 HIV positive female sex workers, and in-depth qualitative interviews were conducted from among 12 HIV positive sex workers.</p><p><b>RESULTS</b>HIV antibody positive rate was 0.8% (181), the age of the 181 subjects were (35.83 ± 9.17) years old, 76 cases (42.0%) were < 35 years old, and 105 cases (58.0%) were ≥ 35 years old. The differences of marital status, workplace class, the last work site among two groups were statistically significant (χ(2) = 20.80, 28.32, 7.83; P < 0.001, P < 0.001, P = 0.020, respectively). Among 181 HIV, the proportion of AIDS awareness was 95.6% (173); the proportion of drug use among ≥ 35 years old age group was 51.4% (54), which was higher than that in < 35 years old age group (34.2%, 26/76) (χ(2) = 5.30, P = 0.021). 96.7% (175) received condom promotion or HIV counseling and testing in the past year. The proportion of continuing to engage in sexual services over 5 years after HIV infection was 48.5% (51/105) and the proportion of receiving antiretroviral treatment was 69.5% (73/105) in ≥ 35 years old age group, which were higher than those in the < 35 age group (30.2% (23/76), 52.6% (40/76); χ(2) = 12.26, 5.36; P = 0.002, 0.021, respectively). In-depth interviews among 12 HIV positive female sex workers found that regular clients, not consistent use of condoms were the main cause of no condom use. Economic and livelihood factors are important reasons for continuing to engage in sexual services among HIV positive sex workers.</p><p><b>CONCLUSION</b>HIV positive sex workers still have high risk behaviors including continuing to engage in commercial sexual service and no condom use after knowing their HIV infection status, and the proportion of using drugs in the ≥ 35 years old group was higher than that in < 35 years old group.</p>

Treatment of type Rockwood Ⅲ acromioclavicular joint dislocation with clavicular hook plate implantation in 56 cases / 中国组织工程研究

BACKGROUND:Which an ideal method to treat type Rockwood Ⅲ acromioclavicular joint dislocation is,traditional or surgical therapy,is still controversial.OBJECTIVE:To investigate the clinical effect of clavicular hook plate implantation on type Rockwood Ⅲ acromioclayicular joint dislocation.METHODS:A total of 56 patients with type Rockwood Ⅲ acromioclavicular joint dislocation were selected from Department of Orthopaedics of Yiling Hospital between December 2005 and June 2008.There were 42 males and 14 females,aged 16-65 years and mean age of 32 years.All patients were treated with clavicular hook plate implantation.Indicators including visual analogue scale (VAS),the United States shoulder and elbow surgeon score (ASES),and Constant and Murley scoring system were tested pre-operatively,one year postoperatively,before internal fixation,and 3 months after internal fixation;additionally,functional changes of the shoulder joint and complications were analyzed before and after clavicular hook plate implantation.RESULTS AND CONCLUSION:The surgery and following-up were successfully achieved in 56 cases.The following-up lasted for 15-30 months,with the mean time of 20 months.The internal fixation was taken out at about 1 year after implantation.Coracoclavicular ligament was repaired in 32 cases but not in the 24 cases.Two patients with acromioclavicular joint dislocation recurrence were excluded,and coracoclavicular ligament therapy was not performed.Shoulder pain,foreign body sensation,and internal fixation failure occurred in two cases.One year after operation,VAS was decreased compared with that before operation,but ASES and Constant and Murley score were significantly increased (P＜0.01).At three months after internal fixation,VAS was decreased compared with that at 1 year after operation,but ASES and Constant and Murley score were increased (P＜0.05).The results demonstrated that clavicular hook plate implantation for treating type Rockwood Ⅲ acromioclavicular joint dislocation is simple and less invasive,thus it is an ideal internal fixation.
