Evaluation of the rapid, multi-country, parallel process, multi-tasking approach to startup of short-term technical assistance to improve service delivery in newborn and child health in the context of USAID's Zika response in four Eastern and Southern Caribbean countries.

Background: In 2018, the USAID Applying Science to Strengthen and Improve Systems (ASSIST) Project started a new partnership with four Eastern and Southern Caribbean countries impacted by the Zika virus: Antigua and Barbuda, Dominica, St. Kitts and Nevis, and St. Vincent and the Grenadines.  The goal of the project was to provide short-term technical assistance (STTA) to strengthen the health systems' capacity to detect newborns and young children potentially affected by Zika and to address their health needs.  To meet these objectives, ASSIST developed an innovative approach based on its existing model for service delivery improvement. This novel approach is known as Rapid, Multi-country, Parallel Process, Multi-tasking Approach for a Project Startup (RMPP-MAPS).  An evaluation was conducted to document the STTA startup activities, to identify enabling and constraining factors, and to capture lessons learned. Methods: An external consultant conducted remote in-depth interviews with individuals involved in the startup using semi-structured interview guides and retrieved data from the review of project documents. Results: Using RMPP-MAPS, the ASSIST Project successfully implemented the startup for complex STTA in four countries within less than four months, spanning mid-May to early September 2018. Project milestones included achieving buy-in from stakeholders, co-developing the technical scope and materials, and rapidly executing critical operational functions.  Dedicated project teams, country leaderships, and local champions were essential to overcoming the main challenges, which included a condensed timeframe, lack of in-country offices, and country-level factors such as a shortage of health care workers and a weak health infrastructure.  Conclusions: The RMPP-MAPS is a feasible and resource-efficient mechanism of interest to implementers, donors, and low and middle-income countries facing temporal and financial limitations to rapidly addressing public health priorities.

Evolving understanding of the epidemiology of HIV and prevention needs among men who have sex with men in Ulaanbaatar, Mongolia.

This study describes HIV and syphilis bio-behavioral survey conducted among 200 men who have sex with men (MSM) recruited via respondent-driven sampling (RDS) between January 4 and February 1, 2012 in Ulaanbaatar, Mongolia. Participants were administered a structured questionnaire and data were analyzed with RDS-network program in STATA. Of 196 participants who agreed to be tested for HIV and syphilis, 21 (10.7 %; weighted 7.5; 95 % CI: 4.9, 11.4) and 8 (4.1 %; weighted 3.4; 95 % CI: 1.7, 6.7) were positive for HIV and syphilis, respectively. Exposure to HIV prevention programs in the last 12 months was reported by 51.8 % (weighted 33.6; 95 % CI: 27.6, 40.1) of participants. This study found high HIV prevalence and limited uptake of HIV prevention services among MSM in Mongolia. Given the concentrated HIV epidemic among MSM in Mongolia, HIV prevention, treatment and care services should focus on MSM as the population group most affected by HIV.

HIV and sexually transmitted infection-related risks among female sex workers in Mongolia: second-generation surveillance survey, 2011-2012.

BACKGROUND: Surveillance studies among female sex workers (FSWs) in Mongolia have found no HIV but high rates of syphilis, ranging from 10.7% in 2002 to 20.8% in 2007. OBJECTIVES: To determine the current prevalence of HIV and syphilis among FSWs, and to identify syphilis risk factors. METHODS: 761 FSWs were recruited by time-location sampling between 2 January and 29 March 2012 in Ulaanbaatar city, Darkhan-Uul, Orkhon, Khuvsgul and Dornod provinces in Mongolia. Participants were administered an anonymous structured survey. Blood samples were tested for HIV and syphilis. Bivariate and multivariate logistic regression analyses were performed to identify factors associated with syphilis. RESULTS: The mean age of participants was 31 (median 30, interquartile range 24-38). HIV knowledge was modest: 41.3% correctly answered all questions. Consistent condom use with clients was reported by 49.1% of participants and exposure to HIV prevention programmes by 50.1%. Although no cases of HIV were found, syphilis prevalence was -27.8% (95% CI 24.3% to 31.7%). In multivariate analyses, variables associated with syphilis were younger age (age >30 years, OR=0.96, 95% CI 0.92 to 0.99) and occurrence of genital ulcer (OR=2.24, 95% CI 1.17 to 4.28). CONCLUSIONS: A syphilis epidemic continues to grow among FSWs in Mongolia. These women are at high risk of HIV transmission if introduced into their sexual networks. With the increase in migration of mining workers in Mongolia, introduction of HIV may be imminent. Efforts to intensify treatment and prevention programmes among FSWs are needed.

HIV among female sex workers in the Central Asian Republics, Afghanistan, and Mongolia: contexts and convergence with drug use.

BACKGROUND: Central Asia is culturally and demographically diverse, both between and within its respective countries. That diversity is represented in the range of individual, network, community, and structural risks for female sex workers (FSWs) regionally. FSWs have several risk factors for HIV acquisition and transmission including behavioral, biological, and structural risk factors. Across Central Asia, sexual risks have become conflated with risks associated with injection and non-injection illicit drug use. METHODS: Peer-reviewed literature databases and gray literature were searched for articles on sex work in Central Asia. The medial subject heading (MeSH) of "sex work" was cross-referenced with terms associated with Uzbekistan, Tajikistan, Turkmenistan, Kazakhstan, Kyrgyzstan, Mongolia, and Afghanistan. RESULTS: HIV prevalence data for FSWs suggest sustained or increasing prevalence in the region. There are increasing data directly linking HIV among FSWs to injection drug use; odds of HIV are up to 20 times higher among FSWs reporting injecting drug use. Though injecting drug use among FSWs is rare in some settings, recreational drugs and alcohol use limits other risk reduction behaviors, such as condom use. CONCLUSIONS: The Central Asian HIV epidemic has traditionally been assumed to be driven nearly exclusively by drug use, resulting in surveillance systems focused on parenteral transmission. The reviewed data highlight limited attention to characterizing the burden of HIV and risk factors for HIV acquisition and transmission among FSWs who use drugs. Moving forward will require enhanced HIV surveillance and research to inform HIV prevention approaches to address all levels of HIV risks affecting FSWs in Central Asia.

Chlamydia trachomatis age-specific prevalence in women who used an internet-based self-screening program compared to women who were screened in family planning clinics.

OBJECTIVES: To determine whether women who collect self-collected vaginal swabs at home demonstrated a higher positivity of Chlamydia trachomatis than women in family planning clinics. METHODS: Collection kits for vaginal swabs were internet requested, collected at home, and mailed to a laboratory for testing; questionnaires were completed about acceptability and sexual risk history. Infected women received treatment at participating clinics. Age-specific prevalences were compared to those from family planning clinics. RESULTS: Chlamydia positivity was 10.3% for 1171 females mailing swabs; prevalences ranged from 3.3% to 5.5% in family planning. Positivity for internet age groups was much higher than those for family planning age groups. The positivity for internet participants ranged from a low of 4.4% in Baltimore in 2005 to a high of 15.2% Baltimore in 2007. Family planning clinic prevalence in Baltimore and Maryland ranged from a low of 3.3% in Baltimore in 2006 to a high of 5.5% in Baltimore in 2008. The median age for all years for internet users in Baltimore and Maryland combined was 23 years; the median age for all years for attendees to family planning clinics who had chlamydia testing performed was 23 years. CONCLUSIONS: Internet recruited women demonstrated higher positivity of chlamydia than those in family planning, providing new options for chlamydia screening programs.

Performance of three nucleic acid amplification tests for detection of Chlamydia trachomatis and Neisseria gonorrhoeae by use of self-collected vaginal swabs obtained via an Internet-based screening program.

Use of self-obtained vaginal specimens processed by nucleic acid amplification tests (NAATs) has significantly increased the utilization of nontraditional locations for Chlamydia trachomatis and Neisseria gonorrhoeae screening programs. One important emerging source of such venues includes home-based self-sampling kits available via the Internet. The objective of our study was to evaluate the performance of three commercially available NAATs (Becton-Dickinson ProbeTec SDA, Gen-Probe Aptima Combo2 TMA, and Roche Amplicor PCR) for detection of C. trachomatis and N. gonorrhoeae in vaginal samples obtained via an Internet-based screening program. From July 2004 to August 2005, 500 self-collected vaginal swabs were tested for C. trachomatis and N. gonorrhoeae by using all three NAATs. Another 500 samples were collected between August 2005 and November 2007 and tested by ProbeTec and Combo2; PCR testing was discontinued due to low specificity for N. gonorrhoeae. All tests were conducted according to the manufacturers' procedures; the "gold standard" for an infected C. trachomatis or N. gonorrhoeae patient was defined as > or = 2 positive NAAT results. Of the first 500 swabs submitted, 46 were C. trachomatis infected (9.2%) and 5 were N. gonorrhoeae infected (1.0%), and 3 of these were coinfected (0.6%). All C. trachomatis and N. gonorrhoeae Combo2-positive/ProbeTec-negative samples were confirmed as true positives by an alternative NAAT. For C. trachomatis, ProbeTec, Combo2, and PCR had sensitivities of 82.6%, 100%, and 100%, with specificities of 100%, 100%, and 99.3%, respectively. For N. gonorrhoeae, ProbeTec, Combo2, and PCR had sensitivities of 80%, 100%, and 100%, with specificities of 100%, 100%, and 98.8%, respectively. Of the total 1,000 swabs submitted, 92 were C. trachomatis infected (9.2%) and 15 were N. gonorrhoeae infected (1.5%), and 7 of these were coinfected (0.7%). There were no ProbeTec-positive/Combo2-negative samples. For C. trachomatis, ProbeTec and Combo2 had sensitivities of 81.5% and 100%, with specificities of 100% and 100%, respectively. For N. gonorrhoeae, ProbeTec and Combo2 had sensitivities of 80% and 100%, with specificities of 100% and 100%, respectively. Overall, ProbeTec had 17 C. trachomatis false-negative results (1.7%) and 3 N. gonorrhoeae false-negative results (0.3%), while Combo2 had none. Our results were consistent with the sensitivities and specificities stated by the manufacturers. NAATs perform well for detection of chlamydia and gonorrhea with self-obtained vaginal swabs shipped in a dry state to a laboratory. For 1,000 self-collected vaginal swabs tested by NAATs, the sensitivities for C. trachomatis and N. gonorrhoeae for Combo2 were 100% and 100%, while they were 81.5% and 80%, respectively, for ProbeTec. For 500 PCR samples, the C. trachomatis sensitivity was 100% and the N. gonorrhoeae sensitivity was 100%, with specificities of 99.3% and 98.8%, respectively.
