Prevalence and Genotype Distribution of Chlamydia trachomatis in Urine among Men Attending STD Clinics in Guangdong Province, China, 2016.

This study aimed to investigate the prevalence and molecular epidemiology of CT infection by examining urine samples among MSCs from different geographic areas of Guangdong province, China. A cross-sectional study was conducted among MSCs from ten HIV sentinel surveillance sites in Guangdong province. CT DNA in men urine samples were extracted and detected by using the Roche cobas® 4800 CT/NG. The ompA genes were amplified by nested polymerase chain reaction (PCR) and sequenced. The leukocyte esterase test was performed by routine urine analysis at local clinics. Of the 1903 samples, 163(8.6%, 95%CI3.8- 16.3%) were found to be positive for CT. The highest prevalence (10.5%) of CT infection was observed among participants aged 21-30. One hundred and thirty CT positive specimens (79.8%, 130/163) were successfully genotyped by nested PCR, resulting in eight genotypes. The most prevalent genotypes were D, E, F, and J, with proportions of 20.8%, 20.0%, 17.7%, and 16.9%, respectively. There was no significant difference in geographic area, leukocyte esterase test and genotype distribution. Promotion of detection and molecular epidemiology research is needed for effective and comprehensive prevention and control programs. PMID: 29279452 [PubMed - as supplied by publisher]

METHODS: In patients with any stage of newly diagnosed syphilis swabs were performed from urethra, rectum, pharynx and cervix according to the gender and type of sexual intercourse. From these smears standard val...

Conclusions This survey collected important information on PHL STD laboratory testing practices. Capacity for important reference laboratory testing, such as GC culture and antimicrobial susceptibility, are needed to support STD programs. Public health laboratories play a key role in STD screening, surveillance, and prevention by offering test methods that are not available at commercial laboratories. Funding constraints affect the resources available for STD screening and surveillance, and thus, it is important to continue to monitor testing practices and the capacity of PHLs to test for STDs.

Objectives Male and transgender women sex workers (TSWs) are vulnerable for sexually transmitted infections (STIs) and human immunodeficiency virus (HIV), and substance use might be a relevant contributing factor. We assessed sociodemographic characteristics and substance use among sex workers; divided into 3 groups: Transgender women sex workers, male sex workers who have sex with men only or also with females (MSW-M), male sex workers who have sex with females only (MSW-F). Methods A survey on substance use and sexual (risk) behavior was offered during routine STI screening at the Prostitution and Health Centre (P&G...

By HANS DUVEFELT, MD Many patients make this or similar requests, especially in January it seems. This phenomenon has its roots in two things. The first is the common misconception that random blood test abnormalities are more likely early warning signs of disease than statistical or biochemical aberrances and false alarms. The other is the perverse policy of many insurance companies to cover physicals and screening tests with zero copay but to apply deductibles and copays for people who need tests or services because they are sick. It is crazy to financially penalize a person with chest pain for going to the ...
