Abstract
Syphilis remains a pressing public health concern with potential severe morbidity if left untreated. To improve syphilis screening, targeted interventions are crucial, especially in at-risk populations. This systematic review synthesises studies that compare syphilis screening in the presence and absence of an intervention. A systematic search of four databases was conducted (Medline, Embase, Cinahl and Scopus). The primary outcomes evaluated included syphilis screening, re-screening and detection rates. Findings were synthesised narratively. Where multiple studies were clinically heterogenous, a pooled odds ratio was calculated. Twenty-four studies were included. A variety of interventions showed promise including clinician alerts, which increased syphilis screening rate (OR range, 1.25-1.45) and patient SMS reminders that mostly improved re-screening/re-attendance rates (OR range, 0.93-4.4). Coupling syphilis serology with routine HIV monitoring increased the proportion of HIV-positive individuals undergoing both tests. However, pooling three studies with this intervention using the outcome of syphilis detection rate yielded inconclusive results (pooled OR 1.722 [95% CI 0.721-2.723], I 2 =24.8%, P =0.264). The introduction of hospital-based packaged testing for screening high-risk individuals is unique given hospitals are not typical locations for public health initiatives. Nurse-led clinics and clinician incentives were successful strategies. Including syphilis screening with other existing programs has potential to increase screening rates (OR range, 1.06-2.08), but requires further investigation. Technology-driven interventions produced cost-effective, feasible and positive outcomes. Challenges were evident in achieving guideline-recommended screening frequencies for men who have sex with men, indicating the need for multifaceted approaches. Wider application of these interventions may improve syphilis screening and detection rates.

ARCHIVES OF SEXUAL BEHAVIOR 2021; 50:3011-3021.

Abstract
Around the world, geosocial networking apps have become widely popular among sexual minority men (SMM). This research analyzed the sexual behaviors and HIV and STI prevention strategies (HIV/STI testing, HIV/STI inquiry, and HIV/STI disclosure) of an online-recruited sample of 284 SMM living in Ecuador. Sexting and oral sex were the most common sexual behaviors among SMM in the sample. Most participants had low perceptions of HIV and STI risk; 85% reported being tested for HIV and 70% for STIs. Being older predicted higher odds of being tested for either HIV or STIs at least once. Being single also predicted HIV testing. Future interventions in the country should explore apps' utility as intervention tools to spread information about sexual health and HIV prevention strategies, such as condom use and event-driven PrEP. Apps can also facilitate connections to sexual health services, including programs for PrEP initiation and linkage to HIV treatment. They should also focus on promoting sexual harm reduction conversations among potential app-met sexual partners.

Abstract
Grindr is a geolocation smartphone application popular among men who have sex with men (MSM) to find sexual partners. We conducted a study to assess if attendance and HIV testing amongst MSM increased due to advertisements on Grindr that promoted our service. We measured clinic website hits by users clicking through from Grindr; we counted self-reported registrations that nominated referral from Grindr; and we compared new patient attendances and HIV tests in MSM with heterosexual men, for the 18 months preceding the intervention and the 18 months of the intervention. During the intervention the clinic's website received 11,799 unique hits from Grindr users. The average monthly rate of attendances by new MSM increased 70.3% from 19.0 to 32.3, compared with a 5.5% increase among new heterosexual men from 45.6 to 48.1. The average monthly rate of HIV tests among MSM increased 43.6% from 47.0 to 67.6, compared with a 3.9% increase amongst heterosexual men from 40.0 to 41.6. The MSM:heterosexual men rate ratio for new patient attendances changed from 0.42 to 0.67 (p < 0.001, adjusted for possible underlying time trends in each period), and for HIV tests this rate ratio changed from 1.18 to 1.63 (p < 0.001, adjusted for possible underlying time trends in each period). The effects of the intervention did not significantly change over the course of the 18-month intervention. This study suggests that advertising on Grindr was effective and durable as a means of increasing attendance and HIV testing rates among MSM in northern Sydney.

The safe use of dating applications among men who have sex with men: a study protocol for a randomised controlled trial to evaluate an interactive web-based intervention to reduce risky sexual behaviours. BMC Public Health 2020; 20:795. [PMID: 32460748 PMCID: PMC7251668 DOI: 10.1186/s12889-020-08914-z] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2020] [Accepted: 05/13/2020] [Indexed: 11/10/2022] Open
Abstract
Background Notably, both international and local studies have found a high prevalence of sexually transmitted infections (STIs) and risky sexual behaviours, such as condomless anal sex, substance misuse in conjunction with sex (‘chemsex’) and group sex, among men who have sex with men (MSM) dating application (app) users. Although the use of dating apps is an emerging sexual risk factor, little effort has been expended on the promotion of safe sex and good sexual health among the users of those apps. Therefore, the aim of the proposed study is to develop and evaluate the effectiveness of an interactive web-based intervention in improving the sexual health of MSM dating app users in Hong Kong. Methods A two-armed randomised controlled trial will be conducted. Chinese MSM dating app users will be recruited and randomly allocated into either the intervention (n = 200) or control group (n = 200). Subjects in the intervention group will receive the web-based intervention containing interactive content that (1) encourages a positive attitude towards consistent condom use and HIV/STI testing and negative attitude towards chemsex and group sex; (2) positions condom use and regular HIV/STI testing as normative; and (3) targets improved perceived self-efficacy concerning condom use and negotiation and HIV/STI testing. The control group will receive only web-based information without sexual health components. Subjects in both groups will be evaluated at baseline and three and 6 months after baseline. The primary outcome will be the frequency of condomless anal sex in the past 3 months. Discussion The proposed study will aid development of culturally relevant health promotion programmes aimed at minimising the potential harm of dating app use and promoting the sexual health of MSM dating app users. The web-based intervention, if found successful, will have important clinical and policy implications, as it can be adopted by the government and non-governmental organisations targeting MSM. Moreover, the proposed intervention can reach many MSM at relatively low cost, and thus has the potential to check the burgeoning HIV/STI epidemic among MSM in Hong Kong in a cost-effective manner. Trial registration International standard randomized controlled trial number (ISRCTN) registry: ISRCTN16681863 registered on 28 April 2020.

Abstract
BACKGROUND Geosocial networking (GSN) app use among men who have sex with men (MSM) has presented new opportunities for increasing the reach and efficiency of sexual health interventions but also poses challenges to HIV/sexually transmitted disease partner notification. Understanding MSM's attitudes toward app-based preventive sexual health services can help inform their development and delivery. METHODS We recruited US MSM who had met a sex partner on GSN apps in the last year to participate in an online survey assessing acceptability and preferences regarding app-based partner notification, health department presence, and sexual health services. Three app-based notification strategies were presented: sending notification messages through participant's/partner's app profile, health department app profile, or in-app anonymous messaging. RESULTS Of 791 respondents, a majority (70%) preferred to be notified by their partner directly; however, most would get tested if notified by health department profile (95%) or anonymous in-app message (85%). Given the options provided, 50% preferred notifying a partner using their own profile, 26% with health department assistance, and 24% via in-app anonymous message. A majority (71%) were comfortable notifying a partner through a health department profile, and 74% were comfortable using in-app anonymous messaging. Most participants (82%) were comfortable with health departments having app profiles to provide sexual health services. CONCLUSIONS Our results suggest that GSN app-based partner notification and sexual health services would be used by and are acceptable to US MSM. Partnering with app companies to integrate these services and increase access to public health programs has potential to improve MSM sexual health.

Abstract
The resurgence of sexually transmissible infections among men who have sex with men is a concern for sexual health. Traditional strategies have relied on the promotion of condom use, regular testing, treatment, and partner management. Future sexually transmissible infection control programs must combine current prevention methods with novel approaches that target the providers, patients, and mechanisms of health care delivery.

Abstract
Middle-aged and older men who have sex with men (MSM) are one of the most underestimated populations with regard to HIV/AIDS infection, despite the worldwide trend of increasing prevalence in recent years. This population also has low rates of testing, although rare studies are done exclusively with middle-aged and older MSM assessing the factors associated with this prevalence. Thus, based on data from an exclusive online survey with middle-aged and older MSM who use geolocation-based dating applications, the purpose of the study was to analyze factors associated with not taking the HIV test among middle-aged (50 years old) and older MSM in Brazil. Using a modification of time-location sampling adapted to virtual reality, 412 volunteers were approached in Grindr®, Hornet®, SCRUFF®, and Daddyhunt®. The multivariate logistic regression model was adopted to produce adjusted odds ratios (ORa), considering a significance level at .05. There were factors associated with not taking the test: being in a relationship (ORa: 0.24; 95% CI [0.10, 0.53]); knowing partner through the applications (ORa: 1.84; 95% CI [1.07, 3.15]); not knowing the serological status (ORa: 5.07; 95% CI [1.88, 13.67]); ejaculating outside of anal cavity (ORa: 1.79; 95% CI [1.04, 3.05]); practicing sex without penetration (ORa: 2.30; 95% CI [1.17, 4.50]); not taking the test as a form of prevention (ORa: 2.83; 95% CI [1.05, 7.68]); and rarely using Viagra in sexual intercourse (ORa: 1.91; 95% CI [1.20, 3.65]). There is a blind spot in the prevalence of HIV testing in older MSM because this population is not being covered by services, which compromises the overall response to HIV, the goals set for universal health coverage.

Abstract
Background In the absence of detailed information about the population size and behaviour data of men-who-have-sex-with-men (MSM), the estimation of prevalence rates of sexually transmitted infections (STIs) and the design of public health interventions become difficult. The aim of the present study is to estimate the lower boundary of age-specific population sizes and retrieve self-reported information from this population. Methods We used publicly accessible data from a large online dating and social network website for MSM in Germany to retrieve data on the age and regional distribution of profiles. The profiles were also stratified by their information on the preferred position during anal intercourse, safer sex, and sexual identity. Results A total of 464,873 user profiles correspond to an average 15.2 profiles per 1,000 male inhabitants in Germany, varying between 7.6 and 45.6 across federal states. Although the information on the absolute numbers for different age groups is limited by the search engine, age-specific relative frequencies were found to increase from 12.9 in the age group of 18 to 20 year olds to 24.6 profiles per 1,000 male inhabitants in the 28 to 30 year olds. The data shows age-specific trends for safer sex with an increasing easiness of reporting “never” engaging in safer sex or stating that safer sex “needs discussion” with increasing age. Around one third of profile owners stated to be versatile with respect to the preferred position in anal intercourse. All other options (“only bottom”, “more bottom”, “only top”, “more top”) were preferred equally likely by roughly 10% of profile owners, respectively. Conclusions Online social network or dating sites can provide some information about specific populations in the absence of other data sources. The presented results are the first to report age-specific rates of MSM per 1,000 male inhabitants in Germany and may be useful to estimate age-specific prevalence or incidence rates as well as to inform health promotion activities and modelling studies for MSM in Germany.

Abstract
Background Understanding where and how young black men who have sex with men (YBMSM) in the southern United States meet their sexual partners is germane to understanding the underlying factors contributing to the ongoing HIV transmission in this community. Men who have sex with men (MSM) commonly use geosocial networking apps to meet sexual partners. However, there is a lack of literature exploring geosocial networking app use in this particular population. Objective Our aim was to examine the characteristics, preferences, and behaviors of a geographically diverse sample of geosocial networking app-using YBMSM in the southern United States. Methods Data were collected from a sample of 75 YBMSM across three cities (Gulfport, Mississippi; Jackson, Mississippi; and New Orleans, Louisiana). Multiple aspects of geosocial networking app use were assessed, including overall app use, age of participant at first app use, specific apps used, reasons for app use, photos presented on apps, logon times and duration, number of messages sent and received, and characteristics of and behaviors with partners met on apps. Survey measures of app-met partner and sexual behavior characteristics assessed at midpoint (Day 7) and completion visits (Day 14) were compared using McNemar’s test or Wilcoxon signed-rank test. In addition, we assessed activity spaces derived from GPS devices that participants wore for 2 weeks. Results Of the 70 participants who responded to the overall app-use item, almost three-quarters (53/70, 76%) had ever used geosocial networking apps. Jack’d was the most commonly used geosocial networking app (37/53, 70%), followed by Adam4Adam (22/53, 42%), and Grindr (19/53, 36%). The mean and median number of apps used were 4.3 (SD 2.7) and 4.0 (range 0-13), respectively. Most app-using participants displayed their face on the profile picture (35/52, 67%), whereas fewer displayed their bare legs (2/52, 4%) or bare buttocks (or ass; 2/52, 4%). The mean age at the initiation of app use was 20.1 years (SD 2.78) ranging from 13-26 years. Two-thirds (35/53, 66%) of the sample reported using the apps to “kill time” when bored. A minority (9/53, 17%) reported using the apps to meet people to have sex/hook up with. The vast majority of participants reported meeting black partners for sex. Over two-thirds (36/53, 68%) reported that the HIV status of their app-met partners was negative, and 26% (14/53) reported that they did not know their partner’s HIV status. There was a significant difference in GPS activity spaces between app using YBMSM compared to nonapp using YBMSM (2719.54 km2 vs 1855.68 km2, P=.011). Conclusions Use of geosocial networking apps to meet sexual partners among our sample of YBMSM in the southern United States was common, with a diverse range of app use behaviors being reported. Further research should characterize the association between geosocial networking app use and engagement in sexual behaviors that increase risk for HIV acquisition and transmission. In addition, geosocial networking apps present a promising platform for HIV prevention interventions targeting YBMSM who use these apps.

Abstract
Little is known about mobile application (app)-based behavior of men who have sex with men (MSM) in Thailand. A cross-sectional online assessment of app users in Bangkok found that more than a quarter have never tested for human immunodeficiency virus (HIV) and 1 in 3 never tested for sexually transmitted infections (STI). STI testing patterns and HIV testing frequency were highly associated with each other in multinomial logistic regression. In the midst of an escalating epidemic where HIV incidence among MSM is highest in Asia, apps can serve to engage those least likely to be reached by traditional methods of recruitment and outreach in Thailand.

Abstract
INTRODUCTION Syphilis is an important sexually transmitted infection (STI). Despite inexpensive and effective treatment, few key populations receive syphilis testing. Innovative strategies are needed to increase syphilis testing among key populations. Areas covered: This scoping review focused on strategies to increase syphilis testing in key populations (men who have sex with men (MSM), sex workers, people who use drugs, transgender people, and incarcerated individuals). Expert commentary: We identified many promising syphilis testing strategies, particularly among MSM. These innovations are separated into diagnostic, clinic-based, and non-clinic based strategies. In terms of diagnostics, self-testing, dried blood spots, and point-of-care testing can decentralize syphilis testing. Effective syphilis self-testing pilots suggest the need for further attention and research. In terms of clinic-based strategies, modifying default clinical procedures can nudge physicians to more frequently recommend syphilis testing. In terms of non-clinic based strategies, venue-based screening (e.g. in correctional facilities, drug rehabilitation centres) and mobile testing units have been successfully implemented in a variety of settings. Integration of syphilis with HIV testing may facilitate implementation in settings where individuals have increased sexual risk. There is a strong need for further syphilis testing research and programs.

Acceptability and effectiveness of using mobile applications to promote HIV and other STI testing among men who have sex with men in Barcelona, Spain. Sex Transm Infect 2018; 94:443-448. [PMID: 29626174 DOI: 10.1136/sextrans-2017-053348] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2017] [Revised: 02/19/2018] [Accepted: 03/12/2018] [Indexed: 11/04/2022] Open
Abstract
OBJECTIVE To evaluate the acceptability and effectiveness of a pilot intervention programme using gay geosocial mobile applications (apps) to offer rapid HIV and other STI tests to men who have sex with men (MSM) in Barcelona between December 2015 and March 2016. METHODOLOGY We offered rapid HIV, syphilis and hepatitis C testing by sending private messages on apps for sexual and social encounters. Acceptance was defined as the proportion of users who favourably responded to the message and effectiveness was defined as the proportion of users who attended our facilities among those who were interested in attending. To identify variables associated with the response to the messages, multivariate logistic regression was used. Adjusted OR (ORa) and 95% CIs were calculated. We collected information on sociodemographics, sexual behaviours and app usage from the contacted user profiles and from users who attended our facilities. A descriptive analysis was carried out. RESULTS 2656 individual messages were sent. Overall, a 38.4% response rate was obtained, 83.0% of them found it acceptable to receive the unsolicited message, and 73.2% effectiveness was obtained. Responders had higher odds of being 45 years or older (ORa=1.48; 95% CI 1.06 to 2.08), being connected at the moment the message was sent or during the previous hour (ORa=1.92; 95% CI 1.38 to 2.68), having a profile photo not exposing bare chest or abdomen (ORa=1.44; 95% CI 1.07 to 1.92) and using the Grindr app (ORa=1.39; 95% CI 1.12 to 1.73). Of those who were tested and took the survey (n=77), 45.5% had not taken an HIV test in over a year, 24.7% had had a previous STI diagnosis, 51.4% had reported anal sex without condom and 52% had consumed alcohol or drugs for sex. CONCLUSIONS The response rate, acceptance and effectiveness observed in this study indicate that this strategy could be a useful tool for promoting STI testing among high-risk MSM population.

Abstract
Objective Researchers and public health professionals have increased their attention to GPS-based social and sexual networking applications (apps) tailored to gay, bisexual, other men who have sex with men (MSM) and transgender women. These populations continue to be disproportionately affected by HIV in the United States, therefore these apps, in particular Grindr, have become an important sampling venue for the recruitment of HIV-related research participants. As such, it is essential to identify differences among app users to avoid potential sampling bias. This paper seeks to identify differences in MSM and transgender women who use Grindr and those who use other similar apps. Methods A community-based participatory research (CBPR) approach was used to recruit participants online who then completed a 25-item anonymous survey. Five domains were assessed: sociodemographics, HIV testing, sexual risk, substance abuse, and use of GPS-based social and sexual networking apps. Results 457 participants completed surveys. There were significant differences in the sociodemographic characteristics by app use, including age, race/ethnicity, sexual orientation, and outness. After adjusting for the sociodemographic characteristics associated with app use, there were significant differences in HIV risk and substance use between the groups. Conclusion This paper is the first to report on findings that compare MSM and transgender women who report using Grindr to MSM and transgender women who report using other similar apps. GPS-based social and sexual networking apps may offer a valuable recruitment tool for future HIV research seeking to recruit populations at increased risk for HIV or those living with HIV for therapeutic trials. Because of the differences identified across users of different apps, these findings suggest that if researchers recruited participants from just one app, they could end up with a sample quite different than if they had recruited MSM and transgender women from other apps.

Abstract
Men who have sex with men (MSM) are increasingly using geosocial networking (GSN) mobile applications (apps) designed for MSM to socialize and seek sex partners. We systematically reviewed studies on the characteristics of app-using MSM and the potential feasibility of app-based HIV interventions. Existing studies provided limited parameters to compare characteristics and sexual behaviors between app-using and non-app-using MSM. Available data showed that: compared to non-app-using MSM, app-using MSM tended to be younger, identified as White (in the US and Australia), have higher educational level, report higher incomes, and had a higher rate of engagement in risky sexual behaviors and STIs. Compared to non-app-using MSM, app-using MSM were more likely to have tested for HIV in lifetime (Pooled odds ratio = 2.1, 95 % confidence interval: 1.7-2.6) and have similar HIV prevalence. Up to 676 MSM were recruited in 1 day via apps. In the current literature, there was a lack of (1) comparable parameters to measure sexual risk; (2) large longitudinal studies to clarify behavioral changes and HIV/STI incidence over time, comparing app-using and non-app-using MSM; (3) studies to examine the feasibility and efficacy of using apps to promote HIV testing among MSM; and (4) studies on similar topics from countries other than the US, Australia, and China. MSM GSN apps should be utilized in future HIV prevention and control endeavors. Researchers and health providers should collaborate with GSN app developers on these endeavors.

Abstract
INTRODUCTION Digital social media platforms represent outlets through which individuals may find partners for sexual encounters. Using a sample of US post-deployment military veterans, the current study evaluated the prevalence of digital sex seeking as well as clinical correlates of psychopathology, suicidal ideation, and sexually transmitted infections (STIs). METHODS Using data from a baseline telephone interview and follow-up internet-based survey, we examined the prevalence of sexual partnering via digital social media platforms in a national sample of 283 US combat veterans. RESULTS Among veterans, 35.5% of men and 8.5% of women reported having used digital social media to meet someone for sex. Individuals who reported having used digital social media to find sexual partners (DSMSP+) as compared to those who did not (DSMSP-) were more likely to be young, male, and in the Marine Corps. After adjusting for sociodemographic variables, DSMSP+ status was associated with post-traumatic stress disorder (OR=2.26, p=0.01), insomnia (OR=1.99, p=0.02), depression (OR=1.95, p=0.03), hypersexuality (OR=6.16, p<0.001), suicidal ideation (OR=3.24, p=0.04), and treatment for an STI (OR=1.98, p=0.04). CONCLUSION Among US post-deployment military veterans, DSMSP+ behaviors were prevalent, particularly among men. The association between DSMSP+ behaviors and PTSD, insomnia, depression, hypersexuality, suicidal ideation, and STIs suggest that veterans who engage in DSMSP+ behaviors should be particularly thoroughly screened and evaluated for these psychiatric concerns and counseled on the benefits of safe sexual practices.

Abstract
INTRODUCTION Syphilis and human immunodeficiency virus (HIV) coinfection disproportionately affects men who have sex with men (MSM), and the rate of coinfection has been increasing over the last decade. HIV and syphilis coinfection is particularly challenging because the infections interact synergistically thereby increasing the risk of acquisition and transmission as well as accelerating disease progression. Areas covered: This paper reviews and summarizes the epidemiology, pathogenesis, diagnosis, clinical management and prevention of HIV and syphilis coinfection among MSM. Expert commentary: Research does not support a different syphilis treatment for coinfected individuals; however, coinfection may warrant a recommendation for antiretroviral therapy. In order to reverse the epidemic of syphilis and HIV coinfection, there needs to be greater awareness, improved cultural sensitivity among health care providers, improved access to preventative services and increased screening for syphilis and HIV.

Abstract
OBJECTIVES The purpose of this study was to evaluate the prevalence of poor sleep health (ie, poor sleep quality and short sleep duration) in a sample of men who have sex with men (MSM). In addition, this study examined whether poor sleep health was associated with depressive symptoms, substance use, and sexual risk behaviors in this sample. DESIGN Cross-sectional survey. PARTICIPANTS Broadcast advertisements were placed on a popular smartphone application for MSM in January 2016 to recruit users in the London metropolitan area (n=202) to complete a Web-based survey, which included validated measures of sleep quality and duration. MEASUREMENTS Poor sleep quality was defined based on self-report as very or fairly bad. Short sleep duration was defined as less than 7 hours each night. Regression models were used to assess associations between sleep variables and self-reported depressive symptoms, substance use, and sexual risk behaviors. RESULTS About one-third (34.6%) of the respondents reported poor sleep quality and almost half (43.6%) reported sleeping less than 7 hours every night. Several poor sleep health variables were independently associated with depressive symptoms, substance use (eg, use of alcohol or marijuana), and condomless anal intercourse. For example, typical nightly sleep duration of less than 7 hours was associated with condomless receptive anal intercourse with a higher number of sexual partners (incidence rate ratio, 2.65; 95% confidence interval: 1.63-4.30; P<.001). CONCLUSION Sleep health promotion interventions should be developed for MSM, which may promote positive mental health as well as reduce substance use and sexual risk behaviors in this population.

Abstract
BACKGROUND Technology-enabled approaches may reach suburban and rural men who have sex with men (MSM) who lack physical venues, where they live for sexually transmitted disease (STD)/HIV prevention efforts. We evaluated using Grindr, an all-male social networking platform, for STD/HIV prevention services to MSM by a suburban Public Health department. METHODS Phase 1 (October 2012-March 2013) focused on acceptability of prevention messages by MSM on Grindr and phase 2 (October 2013-March 2014) Grindr use for implementing testing and linkage-to-care. We compared the number of Public Health encounters with MSM before and after initiation of Grindr use and the proportion of users who remained engaged with Public Health staff after being told they were interacting with a health educator. RESULTS For a 6-month period before Grindr outreach, Public Health had 60 contacts with MSM. Contacts increased to 305 MSM in phase 1, of which 168/213 (79%) remained engaged. In phase 2, among 903 MSM contacts, 69% remained engaged. Asian and Hispanic MSM were more likely to remain engaged with outreach staff; white men were more likely to be not engaged. No significant difference in age between engaged and nonengaged MSM was seen. CONCLUSIONS Grindr outreach by Public Health in a suburban county seems acceptable to MSM and leads to a 14-fold increase in MSM reached for counseling and education compared with a traditional outreach period. Further evaluation of technology-enabled approaches for STD/HIV prevention in suburban and rural MSM is warranted.

Abstract
There are an estimated 10.6 million incident cases of syphilis worldwide each year. We highlight some persistent challenges and emerging trends in the clinical management of syphilis with a particular focus on therapy, serology, diagnostics, and prevention. Decades after the introduction of penicillin, the optimal management of early syphilis continues to be a controversial topic, particularly in the setting of HIV co-infection. Similarly, the need for routine lumbar puncture in HIV co-infected asymptomatic persons is an unanswered question. Despite advances in both automation and point-of-care diagnostics, we continue to rely on indirect measures of disease activity to manage this infection. As syphilis rates in some populations continue to rise, novel and effective prevention strategies are needed.
