Abstract
BACKGROUND In 2010 to 2017, rates of reported chlamydia decreased among young Black women but increased for White women and all men. Because chlamydia case rates can be influenced by changes in prevalence, screening, and other factors, we compared chlamydia prevalence trends in a sentinel population with national case rate trends to understand potential drivers of case rate trends. METHODS Chlamydia prevalence was calculated annually among 16- to 24-year-old entrants to the National Job Training Program (NJTP) in 2010 to 2017. An expectation-maximization-based maximum likelihood approach was used to adjust for misclassification due to imperfect test sensitivity and specificity. Models were stratified by sex, age, and race/ethnicity. A statistically significant trend in prevalence was defined as nonoverlapping 95% confidence intervals comparing 2010 and 2017. Trends in chlamydia prevalence were compared with trends in case rates using percentage change over time; relative changes ≥10% were considered meaningful. RESULTS Among NJTP entrants in 2010 to 2017, chlamydia prevalence was stable for all Black women, whereas case rates decreased for adolescents (-12%) and were stable for 20- to 24-year-olds (-4%). Among adolescent White women, prevalence was stable, whereas case rates increased (+30%). For White women aged 20 to 24 years, prevalence increased +62% and case rates increased +43%. Trends in prevalence differed from trends in case rates for all subgroups of men. CONCLUSIONS Prevalence trends in this sentinel population differed from national case rate trends for Black women, White women, and men, suggesting potential decreased screening among Black women aged 16 to 19 years, increased prevalence among White women aged 20 to 24 years, and increased screening among men.

Abstract
Objectives. To examine long-term gonorrhea prevalence trends from a sentinel surveillance population of young people at elevated risk for gonorrhea.Methods. We analyzed annual cross-sectional urogenital gonorrhea screening data from 191 991 women (2000-2017) and 224 348 men (2003-2017) 16 to 24 years of age entering the National Job Training Program, a US vocational training program. We estimated prevalence among women using an expectation-maximization algorithm incorporated into a logistic regression to account for increases in screening test sensitivity; log-binomial regression was used to estimate prevalence among men.Results. The adjusted gonorrhea prevalence among women followed a U-shaped curve, falling from 2.9% to 1.6% from 2000 through 2011 before rising to 2.7% in 2017. The prevalence among men declined from 1.4% to 0.8% from 2003 through 2017. In the case of both women and men, the prevalence was highest across all study years among those who were Black or American Indian/Alaska Native and those who resided in the South or Midwest.Conclusions. Trends among National Job Training Program enrollees suggest that gonorrhea prevalence is rising among young women while remaining low and steady among young men.

Abstract
The prevalence of sexually transmitted infection (STI) pathogens in Beijing, China, is rarely reported. In this study, 34 911 symptomatic outpatients with suspected genital infections who attended outpatient clinics in a tertiary care hospital were included to investigate the updated prevalence of Ureaplasma urealyticum (UU), Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG) and herpes simplex virus (HSV) from 1 January 2013 to 31 December 2016 in Beijing, China. Results indicated that a decrease trend (UU, CT, NG and HSV) in male and an increase trend (UU, CT and NG) in female were observed during the period. Patients aged 20–39 years old were mostly affected by these pathogens, while the prevalence in patients aged 20–29 years old was the highest, The prevalence of UU in male was significantly lower than in female (31.5% vs. 49.3%, P < 0.05), while the prevalence of NG in male was significantly higher than in female (2.5% vs. 0.8%, P < 0.05). In patients with co-infections, 60.6% of male and 71.4% of female were co-infected by UU + CT. In total, 11.9% and 88.1% of patients with HSV infections were confirmed to be infected by HSV-1 and HSV-2. This study could contribute to a better understanding of the current epidemiological features of UU, NG, CT and HSV among symptomatic patients attending an outpatient clinic in Beijing, China, and thus facilitate to develop more effective intervention, prevention and treatment of STI.

Abstract
OBJECTIVES Social determinants of health (SDHs) are the complex, structural, and societal factors that are responsible for most health inequities. Since 2003, the National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention (NCHHSTP) has researched how SDHs place communities at risk for communicable diseases and poor adolescent health. We described the frequency and types of SDHs discussed in articles authored by NCHHSTP. METHODS We used the MEDLINE/PubMed search engine to systematically review the frequency and type of SDHs that appeared in peer-reviewed publications available in PubMed from January 1, 2009, through December 31, 2014, with a NCHHSTP affiliation. We chose search terms to identify articles with a focus on the following SDH categories: income and employment, housing and homelessness, education and schooling, stigma or discrimination, social or community context, health and health care, and neighborhood or built environment. We classified articles based on the depth of topic coverage as "substantial" (ie, one of ≤3 foci of the article) or "minimal" (ie, one of ≥4 foci of the article). RESULTS Of 862 articles authored by NCHHSTP, 366 (42%) addressed the SDH factors of interest. Some articles addressed >1 SDH factor (366 articles appeared 568 times across the 7 categories examined), and we examined them for each category that they addressed. Most articles that addressed SDHs (449/568 articles; 79%) had a minimal SDH focus. SDH categories that were most represented in the literature were health and health care (190/568 articles; 33%) and education and schooling (118/568 articles; 21%). CONCLUSIONS This assessment serves as a baseline measurement of inclusion of SDH topics from NCHHSTP authors in the literature and creates a methodology that can be used in future assessments of this topic.

Abstract
Gonorrhea is the second most commonly reported infection. It can lead to pelvic inflammatory disease, ectopic pregnancy, and infertility. Rates of gonorrhea decreased after the National Gonorrhea Control Program began in 1972, but stabilized in the mid 1990s. The emergence of antimicrobial resistant strains increases the urgency for enhanced gonorrhea control efforts. To identify possible approaches for improving gonorrhea control, we reviewed historic protocols, reports, and other documents related to the activities of the National Gonorrhea Control Program using Centers for Disease Control and Prevention records and the published literature. The Program was a massive effort that annually tested up to 9.3 million women, and treated up to 85,000 infected partners and 100,000 additional exposed partners. Reported gonorrhea rates fell by 74% between 1976 and 1996, then stabilized. Testing positivity was 1.6-4.2% in different settings in 1976. In 1999-2008, the test positivity of a random sample of 14- to 25-year-olds was 0.4%. Gonorrhea testing rates remain high, however, partner notification efforts decreased in the 1990s as attention shifted to human immunodeficiency virus and other sexually transmitted diseases. The decrease and subsequent stabilization of gonorrhea rates was likely also influenced by changes in behavior, such as increases in condom use in response to acquired immune deficiency syndrome. Renewed emphasis on partner treatment might lead to further decreases in rates of gonorrhea.

Abstract
INTRODUCTION Sexually transmitted infections are common causes of morbidity and mortality, including infertility and certain types of cancer. Alcohol tax increases may decrease sexually transmitted infection rates overall and differentially across population subgroups by decreasing alcohol consumption in general and prior to sex, thus decreasing sexual risk taking and sexually transmitted infection acquisition. This study investigated the effects of a Maryland increase in alcohol beverage sales tax on statewide gonorrhea and chlamydia rates overall and within age, gender, and race/ethnicity subpopulations. METHODS This study used an interrupted time series design, including multiple cross-state comparisons, to examine the effects of the 2011 alcohol tax increase in Maryland on chlamydia and gonorrhea cases reported to the U.S. National Notifiable Disease Surveillance System for January 2003 to December 2012 (N=120 repeated monthly observations, analyzed in 2015). Effects were assessed with Box-Jenkins autoregressive moving average models with structural parameters. RESULTS After the alcohol-specific sales tax increase, gonorrhea rates decreased 24% (95% CI=11%, 37%), resulting in 1,600 fewer statewide gonorrhea cases annually. Cohen's d indicated a substantial effect of the tax increase on gonorrhea rates (range across control group models, -1.25 to -1.42). The study did not find evidence of an effect on chlamydia or differential effects across age, race/ethnicity, or gender subgroups. CONCLUSIONS Results strengthen the evidence from prior studies of alcohol taxes influencing gonorrhea rates and extend health prevention effects from alcohol excise to sales taxes. Alcohol tax increases may be an efficient strategy for reducing sexually transmitted infections.

Abstract
BACKGROUND Prevalence estimates from population-based surveys do not suffer from the same biases as case-report and clinic positivity data and may be better to monitor sexually transmitted disease morbidity over time. METHODS We estimated the prevalence of Neisseria gonorrhoeae in a nationally representative sample of persons aged 14 to 39 years participating in the National Health and Nutrition Examination Survey. RESULTS From 1999 to 2008, the overall prevalence of gonorrhea was 0.27% (95% confidence interval, 0.13%-0.47%). In the 2005 to 2006 and 2007 to 2008 cycles, prevalence approached 0% and was based on too few positive sample persons to obtain reliable estimates. In 2004, most infections were found in 1 survey location. DISCUSSION Given the low prevalence and geographic clustering of disease, gonorrhea estimates from national probability surveys are often imprecise and unstable. In 2008, gonorrhea testing in National Health and Nutrition Examination Survey was discontinued. Continued surveillance of gonorrhea should include case reporting and prevalence estimates from local surveys and sentinel surveillance systems.

Abstract
Secondary analysis of the PID Evaluation and Clinical Health (PEACH) data suggests that among women presenting with signs and symptoms of pelvic inflammatory disease (PID), those who reported oral sex were less likely to have endometritis (adjusted odds ratio [OR] 0.5 [0.3-0.8]) than those who did not report oral sex. Adaptive immunity requires antigenic priming of the lymphatic system. As lymphatic tissue is abundant in the oropharynx, oral sex could lead to effective immune stimulation and prevent PID. To determine whether oral sex could be a protective factor for PID the relationship between self-reported oral sex and endometritis was analysed among 619 women with clinically suspected PID who participated in the PEACH study. Nearly one quarter of participants reported oral sex in the past four weeks. These women also reported a higher number of sexual partners, a new partner within the past four weeks and a higher frequency of sexual intercourse (all P < 0.03). They were more likely to smoke (P < 0.0001), drink alcohol (P < 0.004) and use recreational drugs (P < 0.02). Participants reporting oral sex were significantly less likely to be black or to have a positive test for Neisseria gonorrhoeae (7.8% versus 21.6%, P = 0.001). Women who disclosed oral sex were significantly less likely to have endometritis after adjusting for race, number of partners, recent new partner, smoking, alcohol use and drug use (adjusted OR 0.5 [0.3-0.8]). This is the first paper showing a negative association between oral sex and endometritis. This may be mediated by a protective immune response in the genital tract following priming in the oropharynx. This hypothesis needs to be tested in further studies.

Abstract
Cell surface heparan sulfate (HS), a polysaccharide composed of alternating uronic acid and glucosamine residues, represents a common link that many sexually transmitted infections (STIs) require for infection. Variable modifications within the monomeric units of HS chains together with their unique structural conformations generate heterogeneity, which expands the ability of HS to bind a diverse array of host and microbial proteins. Recent advances made in the field of glycobiology have critically enhanced our understanding of HS and its interactions with microbes and their significance in important human diseases. The role of HS has been elaborated for several STIs to include those caused by herpes simplex virus, human immunodeficiency virus, human papillomavirus, and Chlamydia. In addition, gonorrhea, syphilis, and yeast infections are also dependent on the presence of HS on human target cells. Critical steps such as pathogen adhesion or binding to host cells followed by internalization to enhance intracellular survival and possible spread to other cells are mediated by HS. In addition, HS guided cell signaling plays a role in the development of angiogenesis and inflammation associated with many STIs. Past and ongoing investigations are providing new push for the development of HS-mimetics and analogs as novel prevention strategies against many different STIs. This review article summarizes the significance of HS in STIs and describes how emerging new products that target HS can be used to control the spread of STIs.
