Abstract
Willingness to self-collect vaginal swabs at a pharmacy clinic is of interest as a venue to increase sexually transmissible infections (STIs) screening for chlamydia, gonorrhoea and trichomonas. Women self-collected vaginal swabs at the pharmacy, completed questionnaires and received STI results within 2 h. Women with STIs were offered free treatment. A total of 313 of 777 (40.3%) women consented and prevalence for any STI was 3.9%. Questionnaires demonstrated acceptability for self-collection at the pharmacy, with 63% (95% CI 57.3-68) and 32.3% (95% CI 27.4-37.8) indicating they 'strongly agreed' or 'agreed' that they felt comfortable with pharmacy collection, respectively. Self-collected vaginal swabs for STI testing for women who were at a pharmacy were feasible and acceptable to women.

Abstract
Management of curable sexually-transmitted infections (STI) such as Chlamydia can be revolutionized by highly sensitive nucleic acid testing that is deployable at the point-of-care (POC). Here we report the development of a mobile nucleic acid amplification testing (mobiNAAT) platform utilizing a mobile phone and droplet magnetofluidics to deliver NAAT in a portable and accessible format. By using magnetic particles as a mobile substrate for nucleic acid capture and transport, fluid handling is reduced to particle translocation on a simple magnetofluidic cartridge assembled with reagents for nucleic acid purification and amplification. A mobile phone user interface operating in tandem with a portable Bluetooth-enabled cartridge-processing unit facilitates process integration. We tested 30 potentially Chlamydia trachomatis (CT)-infected patients in a hospital emergency department and confirmed that mobiNAAT showed 100% concordance with laboratory-based NAAT. Concurrent evaluation by a nontechnical study coordinator who received brief training via an embedded mobile app module demonstrated ease of use and reproducibility of the platform. This work demonstrates the potential of mobile nucleic acid testing in bridging the diagnostic gap between centralized laboratories and hospital emergency departments.

Abstract
OBJECTIVES To investigate prevalence of Mycoplasma genitalium, Chlamydia trachomatis, Neisseria gonorrhoeae and Trichomonas vaginalis in men, frequency of co-infections, and association of organisms with urethritis in men. METHODS This was a cross-sectional study of 290 men (age range 19-34 years) attending Baltimore City STD clinics. M genitalium, C trachomatis, N gonorrhoeae and T vaginalis, during 2004 were detected using nucleic acid amplification tests (NAATs) (153 with urethritis and 137 without urethritis). Demographic characteristics and risk factors were ascertained. RESULTS The overall prevalences of infection with C trachomatis, N gonorrhoeae, T vaginalis and M genitalium were 20.3%, 12.8%, 3.4% and 15.2%, respectively. Prevalences in men with urethritis were 32.7%, 24.2%, 5.2% and 22.2% for C trachomatis, N gonorrhoeae, T vaginalis and M genitalium, respectively. Percentages of co-infections were high. All men with N gonorrhoeae had urethritis. C trachomatis and M genitalium were found to be significantly associated with urethritis in univariate analysis and in multiple logistic regression analysis. CONCLUSION The association of M genitalium with urethritis in this study provides confirmation of the importance of screening men for M genitalium as a cause of non-gonococcal urethritis and supports treatment considerations for urethritis for agents other than gonococci and chlamydia.
