Presumptive and follow up treatment associated with gonorrhea and chlamydia testing episodes in STD clinics: Impact of changing treatment guidelines for gonorrhea, STD Surveillance Network, 2015- 2018
Llata E , Braxton J , Asbel L , Huspeni D , Tourdot L , Kerani RP , Cohen S , Kohn R , Schumacher C , Toevs K , Torrone E , Kreisel K . Sex Transm Dis 2022 50 (1) 5-10 BACKGROUND: CDC recommendation for treatment of uncomplicated gonorrhea (NG) were revised in December 2020 and include ceftriaxone monotherapy when chlamydial infection was excluded. We evaluated the impact of these revised treatment recommendations using data from a network of STD clinics prior to the change in guidelines. METHODS: We performed a cross-sectional analysis from 8 STD clinics participating in the STD Surveillance Network from Jan 2015-June 2018 assessing gonorrhea/chlamydia (CT) testing episodes, NAAT results, CT only and NG/CT treatment records, and timing of treatment. We describe the frequency of NG and CT treatment practices and what proportion of patients treated would not have had to receive an anti-chlamydial agent. RESULTS: Of 190,589 episodes that occurred during the study period, 67,895 (35.6%) episodes were associated with a treatment record consistent with gonorrhea and/or chlamydia (CT only (n = 37,530) or NG/CT (n = 30,365)), most (~86%) were prescribed on the same-day as initial testing. Of the 67,895 episodes with corresponding treatment record(s), 42.1% were positive for either NG or CT compared to 3.7% were positive for NG or CT for those not associated with treatment records (n = 122,694 episodes). Among 30,365 episodes associated with NG/CT treatment records, monotherapy would only have been indicated for 10.1% (3,081/30,365) of the episodes as they were treated on follow-up and were NG positive and CT negative. CONCLUSIONS: Treatment was prescribed in one third of NG/CT testing episodes, with the majority provided same day. Despite changes in NG treatment guidelines to ceftriaxone monotherapy, majority of patients would continue to receive an anti-chlamydia agent when treated for gonorrhea in these settings. |
Demographic, Behavioral, and Clinical Characteristics of Persons Seeking Care at Sexually Transmitted Disease Clinics - 14 Sites, STD Surveillance Network, United States, 2010-2018
Llata E , Cuffe KM , Picchetti V , Braxton JR , Torrone EA . MMWR Surveill Summ 2021 70 (7) 1-20 PROBLEM: Sexually transmitted diseases (STDs) are a major cause of morbidity in the United States, with an estimated $15.9 billion in lifetime direct medical costs. Although the majority of STDs are diagnosed in the private sector, publicly funded STD clinics have an important role in providing comprehensive sexual health care services, including STD and HIV screening, for a broad range of patients. In certain cases, STD clinics often are the only source of sexual health care for patients, particularly among gay, bisexual, and other men who have sex with men (MSM). PERIOD COVERED: 2010-2018. DESCRIPTION OF THE SYSTEM: The STD Surveillance Network (SSuN) is an ongoing sentinel surveillance system for monitoring clinical information among patients attending STD clinics. SSuN is a collaboration of competitively selected state and city health departments that conduct facility-based sentinel surveillance in STD clinics. Information routinely collected through the course of patient encounters is obtained for all patients seeking care in the participating STD clinics. This information includes demographic, behavioral, and clinical characteristics (e.g., STD and HIV tests performed and STD and HIV diagnoses). This report presents 2010-2018 SSuN data from 14 STD clinics in five cities (Baltimore, Maryland; New York City, New York; Philadelphia, Pennsylvania; San Francisco, California; and Seattle, Washington) to describe the patient populations seeking care in these STD clinics. Estimated numbers and percentages of patients receiving selected STD-related health services were calculated for each year by using an inverse variance weighted random-effects model, adjusting for heterogeneity among SSuN jurisdictions. Trends in receipt of selected STD-related health services were examined and included HIV screening after an acute STD diagnosis among persons not previously known to have HIV infection, annual chlamydia screening among adolescent and young females, and extragenital chlamydia and gonorrhea screening among MSM. RESULTS: During 2010-2018, the total number of annual visits made in the 14 participating STD clinics decreased 29.8% (from 145,728 to 102,275 visits), and the total number of unique patients examined in the clinics decreased 35.1% (from 94,281 to 61,172 patients). Decreases in the number of unique patients occurred both among men who have sex with women only (42.4%; from 37,842 in 2010 to 21,781 in 2018) and among females (51.4%; from 36,485 in 2010 to 17,721 in 2018). The decreases in the number of female patients were observed across all age groups, although they were more pronounced among females aged ≤24 years (66.4%; from 17,721 in 2010 to 5,962 in 2018). In contrast, the number of patients identified as MSM increased 44.0% (from 12,859 in 2010 to 18,512 in 2018), with the greatest increase among MSM aged ≥25 years (58.6%; from 9,918 in 2010 to 15,733 in 2018). Among visits during which an acute STD (defined as chlamydia, gonorrhea, or primary or secondary syphilis) was diagnosed, the percentage of visits during which an HIV test was performed within approximately 14 days of the STD diagnosis increased from 58.2% in 2010 to 70.2% in 2018. Among those patients tested, 1,672 HIV infections were identified, of which 84.0% were among MSM. Among females aged 15-24 years, the percentage screened for chlamydia in any calendar year increased from 88.6% in 2010 to 90.6% in 2018. However, because fewer females aged 15-24 years attended these clinics during the study period, the crude number of adolescent and young females tested for chlamydia decreased from 14,249 in 2010 to 4,507 in 2018. During 2010-2018, the percentage of females retested after their first positive chlamydia diagnosis during the same year ranged from 11.4% to 13.3%. During 2010-2018, the percentage of MSM tested for rectal chlamydia and rectal gonorrhea increased (from 54.7% to 57.8% and from 55.0% to 58.4%, respectively). During the same period, increases were noted in the percentage of MSM with diagnosed rectal chlamydia (from 15.5% in 2010 to 17.7% in 2018) and rectal gonorrhea (from 13.3% in 2010 to 17.1% in 2018). In contrast with pharyngeal chlamydia, pharyngeal gonorrhea screening was more common (from 69.5% in 2010 to 74.6% in 2018), and the percentage positive doubled during the study period (from 7.3% in 2010 to 14.8% in 2018). Pharyngeal chlamydia testing also increased (from 50.3% in 2010 to 72.9% in 2018), with concurrent decreases in positivity (from 4.2% in 2010 to 2.6% in 2018). INTERPRETATION: During 2010-2018, changes occurred in the demographic composition of patients attending STD clinics participating in SSuN. Understanding trends in the demographic profile of STD patients and services provided can help identify addressable gaps in STD control efforts and direct public health action. Overall, fewer females, especially those aged 15-24 years, accessed care in these STD clinics during the study period. Untreated STDs among adolescent and young females can have serious consequences, including pelvic inflammatory disease and infertility. Additional efforts to monitor where adolescent and young females seek care and to ensure they are receiving quality STD-related health services are needed, especially considering increases in reported cases of STDs among females. Increases in the number of MSM attending STD clinics present a unique opportunity to reach this population with STD and HIV prevention services. Although a large percentage of STD cases are diagnosed outside of STD clinics, publicly funded STD clinics are an important safety-net provider of STD-related health services and provide vital STD-related health services for patient populations at risk for the consequences of STDs and HIV infection. PUBLIC HEALTH ACTIONS: STD-related health services represent effective strategies for preventing STD and HIV transmission and acquisition or STD-related sequelae. Ensuring that all persons receive quality HIV and STD prevention and treatment services is vital for an effective public health approach to reducing STDs. STD clinics provide crucial safety-net services for preventing STD-related morbidity, including timely identification and treatment of curable STDs such as chlamydia, gonorrhea, and syphilis. Increases in the numbers of MSM attending STD clinics participating in SSuN provide additional opportunities for linking patients to high-impact HIV preventive services (e.g., pre-exposure prophylaxis), and the clinics are positioned to facilitate initiation or resumption of treatment among persons living with HIV. |
Investigating the impact of using an alternate classification method for race and Hispanic ethnicity on rates of reported gonorrhea
Picchetti V , Chesson H , Braxton J , Torrone E . Sex Transm Dis 2020 47 (11) 717-723 BACKGROUND: We aimed to examine how the classification of gonorrhea cases by race and Hispanic ethnicity (HE) affects the measurement of racial/HE disparities in the rates of reported gonorrhea. METHODS: We examined gonorrhea cases reported through the National Notifiable Diseases Surveillance System during January 1, 2010-December 31, 2017 and assigned race and HE using 1) "Current classification", where cases with HE are classified as Hispanic regardless of race (e.g., Hispanic, non-Hispanic White, non-Hispanic Black), and 2) "Alternate classification", which separates each race category by HE (e.g., Hispanic White, non-Hispanic White). We estimated annual gonorrhea rates during 2010-2017 by race/HE category and calculated disparity measures (index of disparity, population attributable proportion, and Gini coefficient) for gonorrhea rates under each classification strategy. RESULTS: All disparity measures revealed decreases in racial/HE disparities in the rates of reported gonorrhea during 2010-2017, regardless of classification strategy; however, the magnitude of the disparity and the percent change in the disparity over time varied across disparity measures. CONCLUSIONS: Understanding how classification of race/HE affects observed disparities is critical when monitoring interventions to reduce disparities and improve health equity. |
Pharyngeal gonococcal infections: A cross-sectional study in a network of sexually transmitted disease clinics; STD Surveillance Network (SSuN)-January 2016 to June 2018
Llata E , Braxton J , Asbel L , Huspeni D , Hsu K , Kerani RP , Nguyen TQ , Pathela P , Schumacher C , Toevs K , Torrone E . Sex Transm Dis 2019 46 (12) 777-779 We conducted a cross-sectional analysis using STD clinic data to determine test of cure (TOC) rates among persons diagnosed with pharyngeal gonococcal infections who were treated with a non-ceftriaxone, non-azithromycin therapy. Less than 10% returned for a TOC, highlighting the need to understand factors that can lead to improved compliance. |
Rectal Chlamydia trachomatis and Neisseria gonorrhoeae infections among women reporting anal intercourse
Llata E , Braxton J , Asbel L , Chow J , Jenkins L , Murphy R , Pathela P , Schumacher C , Torrone E . Obstet Gynecol 2018 132 (3) 692-697 OBJECTIVE: To examine the prevalence and treatment of rectal Chlamydia trachomatis and Neisseria gonorrhoeae infections among women reporting receptive anal intercourse in a network of sexually transmitted disease or sexual health clinics and estimate the proportion of missed infections if women were tested at the genital site only. METHODS: We conducted a cross-sectional analysis of C trachomatis and N gonorrhoeae test results from female patients reporting receptive anal intercourse in the preceding 3 months during visits to 24 sexually transmitted disease clinics from 2015 to 2016. Primary outcomes of interest were 1) anatomic site-specific C trachomatis and N gonorrhoeae testing and positivity among women attending selected U.S. sexually transmitted disease clinics who reported receptive anal intercourse and 2) the proportion of rectal infections that would have remained undetected if only genital sites were tested. RESULTS: Overall, 7.4% (3,743/50,785) of women reported receptive anal intercourse during the 2 years. Of the 2,818 women tested at both the genital and rectal sites for C trachomatis, 292 women were positive (61 genital only, 60 rectal only, and 171 at both sites). Of the 2,829 women tested at both the genital and rectal sites for N gonorrhoeae, 128 women were positive (31 genital only, 23 rectal only, and 74 at both sites). Among women tested at both anatomic sites, the proportion of missed C trachomatis infections would have been 20.5% and for N gonorrhoeae infections, 18.0%. CONCLUSION: Genital testing alone misses approximately one fifth of C trachomatis and N gonorrhoeae infections in women reporting receptive anal intercourse in our study population. Missed rectal infections may result in ongoing transmission to other sexual partners and reinfection. |
New human immunodeficiency virus diagnoses among men who have sex with men attending STD clinics, STD Surveillance Network, January 2010 to June 2013
Llata E , Braxton J , Asbel L , Kerani RP , Murphy R , Pugsley R , Pathela P , Schumacher C , Tabidze I , Weinstock HS . Sex Transm Dis 2018 45 (9) 577-582 OBJECTIVE: To estimate new HIV diagnosis rates among HIV negative MSM who are repeatedly tested for HIV in sexually transmitted disease (STD) clinics, and assess the impact of demographic and disease-specific characteristics that are associated with higher HIV diagnosis rates. STUDY DESIGN: Retrospective analysis using 2010-2013 data from the STD Surveillance Network (SSuN), a sentinel surveillance system comprised of health departments in 12 cities conducting sentinel surveillance in 40 STD clinics. We analyzed data from all MSM repeatedly (>/=2 times) tested for HIV, with an initial negative HIV test required for staggered cohort entry. Follow-up time was accrued from the date of the first negative HIV test to the most recent negative test or the first positive HIV test. STD diagnoses during the follow-up period were reviewed. We estimated HIV diagnoses rates (number of HIV diagnoses/total number of person-years at risk) by demographic and clinical characteristics with 95% confidence intervals (CI) using an inverse variance weighted random effects model, adjusting for heterogeneity between SSuN jurisdictions. RESULTS: Overall, 640 HIV diagnoses occurred among 14,824 individuals and 20,951.6 person-years (PY) of observation, for an adjusted incidence of HIV diagnosis of 3.0 per 100 PY (95% CI 2.6, 3.4). Rates varied across race/ethnicity groups with the highest rate among Blacks (4.7/100 PY; 95% CI 4.1-5.3) followed by Hispanics, Whites and persons of other races/ethnicities. MSM having a diagnosis of P&S syphilis on or after the first negative HIV test had a higher new HIV diagnosis rate (7.2/100 PY; 95% CI 5.8-9.0) compared to MSM who did not have a P&S syphilis diagnosis (2.8/100 PY; 95% CI 2.6-3.1). MSM who tested positive for rectal gonorrhea (6.3/100 PY; 95% CI 5.7-6.9) or rectal chlamydia (5.6/100 PY; 95% CI 4.6-6.6) had higher rates of new HIV diagnosis when compared to those with negative test results. CONCLUSIONS: MSM attending SSuN STD clinics have high rates of new HIV diagnoses, particularly those with a previous diagnosis of P&S syphilis, rectal chlamydia and/or gonorrhea. STD clinics continue to be important clinical setting for diagnosing HIV among MSM populations. |

Concordance between anal and oral human papillomavirus (HPV) infections among young men who have sex with men
Steinau M , Gorbach P , Gratzer B , Braxton J , Kerndt PR , Crosby RA , Unger ER , Markowitz LE , Meites E . J Infect Dis 2017 215 (12) 1832-1835 Prevalence of human papillomavirus (HPV) infections was assessed among 1033 young men who have sex with men (MSM) aged 18-26 years. HPV (any type) was detected in 742 (71.8%) anal specimens and 101 (9.8%) oral specimens. Although HPV was detected in specimens from both anatomical sites in 83 (8.0%) participants, type-specific concordance for at least one HPV type was found in only 35 (3.4%) participants. HIV and smoking were associated with higher prevalence at both sites and frequency of concordant types. Coinfections of identical HPV types were rare, suggesting independent infection events and/or different modes of clearance. |
Keeping an eye on chlamydia and gonorrhea conjunctivitis in infants in the United States, 2010–2015
Kreisel K , Weston E , Braxton J , Llata E , Torrone E . Sex Transm Dis 2017 44 (6) 356-358 Perinatal transmission of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (GC) can result in conjunctivitis in infants. We examined national rates of reported CT/GC conjunctivitis among infants. Surveillance of these infections is heavily affected by the completeness of reported data on specimen source and age. Alternative data sources should be evaluated. |
A community-based lifestyle and weight loss intervention promoting a Mediterranean-style diet pattern evaluated in the stroke belt of North Carolina: The Heart Healthy Lenoir Project
Keyserling TC , Samuel-Hodge CD , Pitts SJ , Garcia BA , Johnston LF , Gizlice Z , Miller CL , Braxton DF , Evenson KR , Smith JC , Davis GB , Quenum EL , Elliott NT , Gross MD , Donahue KE , Halladay JR , Ammerman AS . BMC Public Health 2016 16 732 BACKGROUND: Because residents of the southeastern United States experience disproportionally high rates of cardiovascular disease (CVD), it is important to develop effective lifestyle interventions for this population. METHODS: The primary objective was to develop and evaluate a dietary, physical activity (PA) and weight loss intervention for residents of the southeastern US. The intervention, given in eastern North Carolina, was evaluated in a 2 year prospective cohort study with an embedded randomized controlled trial (RCT) of a weight loss maintenance intervention. The intervention included: Phase I (months 1-6), individually-tailored intervention promoting a Mediterranean-style dietary pattern and increased walking; Phase II (months 7-12), option of a 16-week weight loss intervention for those with BMI ≥ 25 kg/m(2) offered in 2 formats (16 weekly group sessions or 5 group sessions and 10 phone calls) or a lifestyle maintenance intervention; and Phase III (months 13-24), weight loss maintenance RCT for those losing ≥ 8 lb with all other participants receiving a lifestyle maintenance intervention. Change in diet and PA behaviors, CVD risk factors, and weight were assessed at 6, 12, and 24 month follow-up. RESULTS: Baseline characteristics (N = 339) were: 260 (77 %) females, 219 (65 %) African Americans, mean age 56 years, and mean body mass index 36 kg/m(2). In Phase I, among 251 (74 %) that returned for 6 month follow-up, there were substantial improvements in diet score (4.3 units [95 % CI 3.7 to 5.0]), walking (64 min/week [19 to 109]), and systolic blood pressure (-6.4 mmHg [-8.7 to -4.1]) that were generally maintained through 24 month follow-up. In Phase II, 138 (57 group only, 81 group/phone) chose the weight loss intervention and at 12 months, weight change was: -3.1 kg (-4.9 to -1.3) for group (N = 50) and -2.1 kg (-3.2 to -1.0) for group/phone combination (N = 75). In Phase III, 27 participants took part in the RCT. At 24 months, weight loss was -2.1 kg (-4.3 to 0.0) for group (N = 51) and -1.1 kg (-2.7 to 0.4) for combination (N = 72). Outcomes for African American and whites were similar. CONCLUSIONS: The intervention yielded substantial improvement in diet, PA, and blood pressure, but weight loss was modest.

Monitoring for Human Papillomavirus Vaccine Impact Among Gay, Bisexual, and Other Men Who Have Sex With Men-United States, 2012-2014
Meites E , Gorbach PM , Gratzer B , Panicker G , Steinau M , Collins T , Parrish A , Randel C , McGrath M , Carrasco S , Moore J , Zaidi A , Braxton J , Kerndt PR , Unger ER , Crosby RA , Markowitz LE . J Infect Dis 2016 BACKGROUND: Gay, bisexual, and other men who have sex with men (MSM) are at high risk for HPV; vaccination is recommended for U.S. males, including MSM through age 26. We assessed evidence of HPV among vaccine-eligible MSM and transgender women to monitor vaccine impact. METHODS: During 2012-14, MSM age 18-26 at selected clinics completed a computer-assisted self-interview regarding sexual behavior, HIV status, and vaccinations. Self-collected anal swab and oral rinse specimens were tested for HPV DNA (37 types) by L1 consensus PCR; serum was tested for HPV antibodies (4 types) by multiplexed VLP-based IgG direct ELISA. RESULTS: Among 922 vaccine-eligible participants, mean age was 23, and mean number of lifetime sex partners was 37. Among 834 without HIV, any anal HPV was detected in 69.4% and any oral HPV in 8.4%, yet only 8.5% had evidence of exposure to all quadrivalent vaccine types. In multivariate analysis, HPV prevalence varied significantly (p<0.05) by HIV status, sexual orientation, and lifetime sex partners, but not race/ethnicity. DISCUSSION: Most young MSM lacked evidence of current or past infection with all vaccine-type HPV, suggesting they could benefit from vaccination. Vaccination impact among MSM may be assessed by monitoring HPV prevalence, including in self-collected specimens. |
Early syphilis among men who have sex with men in the US Pacific Northwest, 2008-2013: Clinical management and implications for prevention
Petrosky E , Fanfair RN , Toevs K , DeSilva M , Schafer S , Hedberg K , Braxton J , Walters J , Markowitz L , Hariri S . AIDS Patient Care STDS 2016 30 (3) 134-140 Substantial increases in syphilis during 2008-2013 were reported in the US Pacific Northwest state of Oregon, especially among men who have sex with men (MSM). The authors aimed to characterize the ongoing epidemic and identify possible gaps in clinical management of early syphilis (primary, secondary, and latent syphilis <=1 year) among MSM in Multnomah County, Oregon to inform public health efforts. Administrative databases were used to examine trends in case characteristics during 2008-2013. Medical records were abstracted for cases occurring in 2013 to assess diagnosis, treatment, and screening practices. Early syphilis among MSM increased from 21 cases in 2008 to 229 in 2013. The majority of cases occurred in HIV-infected patients (range: 55.6%-69.2%) diagnosed with secondary syphilis (range: 36.2%-52.4%). In 2013, 119 (51.9%) cases were diagnosed in public sector medical settings and 110 (48.0%) in private sector settings. Over 80% of HIV-infected patients with syphilis were in HIV care. Although treatment was adequate and timely among all providers, management differed by provider type. Among HIV-infected patients, a larger proportion diagnosed by public HIV providers than private providers were tested for syphilis at least once in the previous 12 months (89.6% vs. 40.0%; p<0.001). The characteristics of MSM diagnosed with early syphilis in Multnomah County remained largely unchanged during 2008-2013. Syphilis control measures were well established, but early syphilis among MSM continued to increase. The results suggest a need to improve syphilis screening among private clinics, but few gaps in clinical management were identified. |
Reduction in Human Papillomavirus Vaccine Type Prevalence Among Young Women Screened for Cervical Cancer in an Integrated US Healthcare Delivery System in 2007 and 2012-2013
Dunne EF , Naleway A , Smith N , Crane B , Weinmann S , Braxton J , Steinau M , Unger ER , Markowitz LE . J Infect Dis 2015 212 (12) 1970-5 BACKGROUND: In the U.S., HPV vaccine is recommended for 11 and 12 year olds, and for young adults not previously vaccinated. Early vaccine impact can be measured by reductions in vaccine type (VT) HPV prevalence. METHODS: Consecutive residual cervical specimens were retained from women aged 20-29 years in Kaiser Permanente Northwest in 2007, 2012, and 2013. HPV genotypes were determined using L1 consensus PCR with type-specific hybridization to detect 37 types, including VT HPV (HPV type 6, 11, 16, 18). We compared HPV prevalence in 2007 and 2012-2013, and we evaluated predictors of VT and any HPV prevalence in 2012-2013. RESULTS: In 2012-2013, 31.9% of 4181 women had initiated HPV vaccination. VT HPV decreased from 10.6% in 2007, to 6.2% in 2012-2013 (p<0.001). In 2012-2013, VT HPV was significantly lower among those who initiated vaccination <19 years (adjusted prevalence ratio (aPR) 0.1, 95% Confidence Interval (CI) 0.1, 0.3) compared to those who were not vaccinated, and higher among those who had chlamydia, HIV or pregnancy testing in the last year compared to those who did not have testing (aPR 1.4, 95% CI 1.1, 1.8). CONCLUSIONS: Reduction in VT HPV was found in young women in an integrated healthcare delivery system within 6 years of vaccine introduction indicating early HPV vaccine impact. |
A cancer center's approach to engaging African American men about cancer: the Men's Fellowship Breakfast, southeastern Michigan, 2008-2014
Langford AT , Griffith DM , Beasley DD , Braxton EI . Prev Chronic Dis 2014 11 E164 BACKGROUND: Despite disproportionate rates of cancer morbidity and mortality among African American men, few community-based efforts have been developed and sustained to educate African American men about cancer. The University of Michigan Comprehensive Cancer Center implemented a series of breakfasts to improve cancer awareness, screening, and education among African American men. This article describes the rationale for and history of the community intervention. COMMUNITY CONTEXT: The 21 breakfasts were held from 2008 through mid-2014 in Ypsilanti and Ann Arbor, Michigan. Ypsilanti ranks below Michigan and the nation on most socioeconomic indicators, although most residents are high school graduates (88% in Ypsilanti and 96.5% in Ann Arbor). African American men in Ypsilanti have higher death rates for diseases associated with poor diet and inadequate physical activity compared with Ypsilanti whites and general populations in Michigan and the nation. METHODS: We conducted a multicomponent qualitative process evaluation including staff meetings, conversations with participants, and focus groups. We collected 425 post-event surveys to evaluate the breakfasts quantitatively. OUTCOMES: Participants were African American (85%), were aged 51 to 70 years (54%), had health insurance (89%), and had some college education (38%). Fifty-three percent of participants reported interest in the breakfast topics including nutrition; 46%, prostate cancer; 34%, colorectal cancer, and 32%, pain management; 62% reported willingness to participate in a clinical trial. INTERPRETATION: African American men are interested in learning about health and are willing to attend a health-focused breakfast series. The Men's Fellowship Breakfast is a promising strategy for bringing men together to discuss cancer screening and risk reduction. |
Extragenital gonorrhea and chlamydia testing and infection among men who have sex with men - STD Surveillance Network, United States, 2010-2012
Patton ME , Kidd S , Llata E , Stenger M , Braxton J , Asbel L , Bernstein K , Gratzer B , Jespersen M , Kerani R , Mettenbrink C , Mohamed M , Pathela P , Schumacher C , Stirland A , Stover J , Tabidze I , Kirkcaldy RD , Weinstock H . Clin Infect Dis 2014 58 (11) 1564-70 BACKGROUND: Gonorrhea (GC) and chlamydia (CT) are the most commonly reported notifiable diseases in the U.S. CDC recommends that men who have sex with men (MSM) be screened for urogenital GC/CT, rectal GC/CT, and pharyngeal GC. We describe extragenital GC/CT testing and positivity among MSM attending sexually transmitted disease (STD) clinics. METHODS: The STD Surveillance Network collects patient data from 42 STD clinics. We assessed the proportion of MSM attending these clinics during July 2011-June 2012 who were tested and positive for extragenital GC/CT at their most recent visit or in the preceding 12 months and the number of extragenital infections that would have remained undetected with urethral screening alone. RESULTS: Of 21,994 MSM, 83.9% were tested for urogenital GC, 65.9% for pharyngeal GC, 50.4% for rectal GC, 81.4% for urogenital CT, 31.7% for pharyngeal CT, and 45.9% for rectal CT. Of MSM tested, 11.1% tested positive for urogenital GC, 7.9% for pharyngeal GC, 10.2% for rectal GC, 8.4% for urogenital CT, 2.9% for pharyngeal CT, and 14.1% for rectal CT. Over 70% of extragenital GC infections and 85% of extragenital CT infections were associated with negative urethral tests at the same visit and would not have been detected with urethral screening alone. CONCLUSIONS: Extragenital GC/CT was common among MSM attending STD clinics, but many MSM were not tested. Most extragenital infections would not have been identified, and likely would have remained untreated, with urethral screening alone. Efforts are needed to facilitate implementation of extragenital GC/CT screening recommendations for MSM. |
Prothrombin G20210A mutation is associated with young-onset stroke: the genetics of early-onset stroke study and meta-analysis.
Jiang B , Ryan KA , Hamedani A , Cheng Y , Sparks MJ , Koontz D , Bean CJ , Gallagher M , Hooper WC , McArdle PF , O'Connell JR , Stine OC , Wozniak MA , Stern BJ , Mitchell BD , Kittner SJ , Cole JW . Stroke 2014 45 (4) 961-7 BACKGROUND AND PURPOSE: Although the prothrombin G20210A mutation has been implicated as a risk factor for venous thrombosis, its role in arterial ischemic stroke is unclear, particularly among young adults. To address this issue, we examined the association between prothrombin G20210A and ischemic stroke in a white case-control population and additionally performed a meta-analysis. METHODS: From the population-based Genetics of Early Onset Stroke (GEOS) study, we identified 397 individuals of European ancestry aged 15 to 49 years with first-ever ischemic stroke and 426 matched controls. Logistic regression was used to calculate odds ratios (ORs) in the entire population and for subgroups stratified by sex, age, oral contraceptive use, migraine, and smoking status. A meta-analysis of 17 case-control studies (n=2305 cases <55 years) was also performed with and without GEOS data. RESULTS: Within GEOS, the association of the prothrombin G20210A mutation with ischemic stroke did not achieve statistical significance (OR=2.5; 95% confidence interval [CI]=0.9-6.5; P=0.07). However, among adults aged 15 to 42 years (younger than median age), cases were significantly more likely than controls to have the mutation (OR=5.9; 95% CI=1.2-28.1; P=0.03), whereas adults aged 42 to 49 years were not (OR=1.4; 95% CI=0.4-5.1; P=0.94). In our meta-analysis, the mutation was associated with significantly increased stroke risk in adults ≤55 years (OR=1.4; 95% CI=1.1-1.9; P=0.02), with significance increasing with addition of the GEOS results (OR=1.5; 95% CI=1.1-2.0; P=0.005). CONCLUSIONS: The prothrombin G20210A mutation is associated with ischemic stroke in young adults and may have an even stronger association among those with earlier onset strokes. Our finding of a stronger association in the younger young adult population requires replication. |
Trichomonas vaginalis in selected US sexually transmitted disease clinics: testing, screening, and prevalence
Meites E , Llata E , Braxton J , Schwebke JR , Bernstein KT , Pathela P , Asbel LE , Kerani RP , Mettenbrink CJ , Weinstock HS . Sex Transm Dis 2013 40 (11) 865-9 BACKGROUND: Trichomonas vaginalis is the most prevalent nonviral sexually transmitted infection in the United States, affecting 3.1% of women of reproductive age. Infection is associated with HIV acquisition and pelvic inflammatory disease. In the United States, Centers for Disease Control and Prevention guidelines recommend testing all women with vaginal discharge for T. vaginalis, but except for HIV-infected women, there are no national guidelines for screening asymptomatic persons. The objective of this analysis is to assess testing and screening practices for T. vaginalis among symptomatic and asymptomatic women in the sexually transmitted disease (STD) clinic setting. METHODS: We analyzed data on demographics, clinical presentation, and laboratory testing for all women visiting a clinician in 2010 to 2011 at any of 15 STD clinics participating in the STD Surveillance Network. Prevalence of laboratory-confirmed T. vaginalis infection was calculated among symptomatic women tested and among asymptomatic women screened. RESULTS: A total of 59,176 women visited STD clinicians: 39,979 were considered symptomatic and 19,197 were considered asymptomatic for T. vaginalis infection, whereas 211 were HIV-infected. Diagnostic practices varied by jurisdiction: 4.0% to 96.1% of women were tested or screened for T. vaginalis using any laboratory test. Among 17,952 symptomatic women tested, prevalence was 26.2%. Among 3909 asymptomatic women screened, prevalence was 6.5%. Among 92 HIV-infected women tested/screened, prevalence was 29.3%. CONCLUSIONS: Trichomoniasis is common among STD clinic patients. In this analysis, most STD clinics tested symptomatic women seeking care, in accordance with national guidelines. All HIV-infected women should be screened annually. Additional evidence and national guidance are needed regarding potential benefits of T. vaginalis screening in other asymptomatic women. |
Masculinity, condom use self-efficacy and abusive responses to condom negotiation: the case for HIV prevention for heterosexual African-American men
Raiford JL , Seth P , Braxton ND , Diclemente RJ . Sex Health 2013 10 (5) 467-9 BACKGROUND: This study explored the role of masculinity and perceived condom use skills in African-American men's abusive response to female partners' condom requests. METHODS: Eighty African-American men aged 18-29 years completed measures on sexual behaviour, responses to condom requests, condom use self-efficacy and other masculine constructs. Men also were tested for sexually transmissible infections. RESULTS: Men's condom use self-efficacy explained 16.5% of the variance in abusive response to condom requests, beyond demographics and masculine constructs. The full model accounted for 63% of the variance. CONCLUSIONS: Many HIV interventions with women encourage condom negotiation. Findings highlight the need to address men's condom use skills and masculine norms. |
Gender differences in sexual risk behaviours and sexually transmissible infections among adolescents in mental health treatment
Seth P , Lang DL , Diclemente RJ , Braxton ND , Crosby RA , Brown LK , Hadley W , Donenberg GR . Sex Health 2012 9 (3) 240-6 BACKGROUND: Adolescents with a history of psychiatric disorder(s) are particularly vulnerable to contracting sexually transmissible infections (STIs) as a result of psychological and emotional states associated with higher rates of risky sexual behaviour. The present study examined gender differences in sexual risk behaviours and STI among adolescents in mental health treatment. METHODS: Three hundred and seventy nine sexually active adolescents, aged 13-18 years, from a larger multisite study, who received mental health treatment during the past year, completed an audio computer-assisted self interview assessing sociodemographics, psychiatric symptomatology and HIV/STI risk behaviours, and provided urine specimens tested for STI. RESULTS: After controlling for covariates, multivariate logistic regression models indicated that female adolescents were more likely to have had an HIV test (adjusted odds ratio (AOR)=3.2, P=0.0001), obtain their HIV test results (AOR=2.9, P=0.03), refuse sex out of fear for STI acquisition (AOR=1.7, P=0.04), or avoid a situation that might lead to sex (AOR=2.4, P=0.001), and were less likely to have a casual sex partner (AOR=0.40, P=0.002). Additionally, females were more likely to report inconsistent condom use (AOR=2.60, P=0.001) and have a STI (AOR=9.1, P=0.0001) than their male counterparts. CONCLUSIONS: Female adolescents receiving mental health treatment were more than nine times as likely to have an STI and more likely to use condoms inconsistently. The standard of care for mental health practice for adolescents should include referrals for STI screening and treatment as well as assessment and discussion of risky sexual behaviours as part of the treatment plan when indicated. Effective programs should address gender-specific communication and behavioural skills. |
Interpersonal- and community-level predictors of intimate partner violence perpetration among African American men
Raiford JL , Seth P , Braxton ND , Diclemente RJ . J Urban Health 2012 90 (4) 784-95 Intimate partner violence (IPV) has been associated with adverse physical, psychoemotional, and sexual health, and African American women are at higher risk for experiencing IPV. Considering African American women predominantly have African American male partners, it is essential to identify factors associated with IPV perpetration among African American men. The present study examined attitudes toward IPV, ineffective couple conflict resolution, exposure to neighborhood violence, and the interplay of these factors as predictors of IPV perpetration. A community sample of 80 single, heterosexual, African American men between 18 and 29 years completed measures assessing sociodemographics, attitudes towards IPV, perceived ineffective couple conflict resolution, exposure to neighborhood violence, and IPV perpetration during the past 3 months. Hierarchical multiple linear regression analyses, with age, education, and public assistance as covariates, were conducted on 65 men who reported being in a main relationship. Couple conflict resolution and exposure to neighborhood violence moderated the relation between attitudes supporting IPV and IPV perpetration. Among men who reported high ineffective couple conflict resolution and high exposure to neighborhood violence, IPV perpetration increased as attitudes supporting IPV increased. The findings indicated that interpersonal- and community-level factors interact with individual level factors to increase the risk of recent IPV perpetration among African American men. While IPV prevention should include individual-level interventions that focus on skills building, these findings also highlight the importance of couple-, community-, and structural-level interventions. |
Trichomonas vaginalis antimicrobial drug resistance in 6 US cities, STD Surveillance Network, 2009-2010
Kirkcaldy RD , Augostini P , Asbel LE , Bernstein KT , Kerani RP , Mettenbrink CJ , Pathela P , Schwebke JR , Secor WE , Workowski KA , Davis D , Braxton J , Weinstock HS . Emerg Infect Dis 2012 18 (6) 939-43 Nitroimidazoles (metronidazole and tinidazole) are the only recommended drugs for treating Trichomonas vaginalis infection, and previous samples that assessed resistance of such isolates have been limited in geographic scope. We assessed the prevalence of in vitro aerobic metronidazole and tinidazole resistance among T. vaginalis isolates from multiple geographic sites in the United States. Swab specimens were obtained from women who underwent routine pelvic examinations at sexually transmitted disease clinics in 6 US cities. Cultured T. vaginalis isolates were tested for nitroimidazole resistance (aerobic minimum lethal concentration [MLC] >50 microg/mL). Of 538 T. vaginalis isolates, 23 (4.3%) exhibited low-level in vitro metronidazole resistance (minimum lethal concentrations 50-100 microg/mL). No isolates exhibited moderate- to high-level metronidazole resistance or tinidazole resistance. Results highlight the possibility that reliance on a single class of antimicrobial drugs for treating T. vaginalis infections may heighten vulnerability to emergence of resistance. Thus, novel treatment options are needed. |
Application of the time-series approach to assess the temporal trend of racial disparity in chlamydia prevalence in the US National Job Training Program
Tian LH , Satterwhite CL , Braxton JR , Groseclose SL . Am J Epidemiol 2011 173 (2) 217-24 The authors applied a time-series approach to assess the temporal trend of racial disparity in chlamydia prevalence between young, socioeconomically disadvantaged blacks and whites entering the US National Job Training Program. Racial disparity was defined as the arithmetic difference between age group-, specimen type-, and region of residence-standardized chlamydia prevalences in blacks and whites. A regression with autoregressive moving average errors model was employed to adjust for serial correlation. Data from 46,849 women (2006-2008) and 136,892 men (2004-2008) were analyzed. Racial disparity significantly decreased among women (by an average of 0.122% per 2-month interval; P < 0.05) but not among men (-0.010%, P = 0.57). Chlamydia prevalence significantly declined for black women (-0.139% per 2-month interval; P = 0.004), black men (-0.045%, P < 0.001), and white men (-0.035%, P = 0.002) but not for white women (-0.028%, P = 0.413). Despite the decreases among black women and black men, the black-white disparities remained high for both sexes; in 2008, the racial disparity was 8.1% (95% confidence interval: 6.8, 9.3) for women and 9.0% (95% confidence interval: 8.4, 9.6) for men. These findings suggest that current chlamydia control efforts may be reaching young black men and women but need to be scaled up or modified to address the excess risk among blacks. |
Trichomonas vaginalis prevalence, incidence, risk factors and antibiotic-resistance in an adolescent population
Krashin JW , Koumans EH , Bradshaw-Sydnor AC , Braxton JR , Secor WE , Sawyer MK , Markowitz LE . Sex Transm Dis 2010 37 (7) 440-4 OBJECTIVE: To determine the prevalence and incidence of trichomoniasis, risk factors for infection, and the prevalence of metronidazole- and tinidazole-resistant Trichomonas vaginalis in female adolescents. METHODS: Nonpregnant, HIV-seronegative, sexually active females (13-19 years) visiting an inner city public primary care clinic were tested for T. vaginalis by wet mount and culture, and interviewed about risk-taking behavior every 6 months. Infected patients were treated with a 2 g oral dose of metronidazole. Isolates from positive T. vaginalis cultures were tested for in vitro resistance to metronidazole and tinidazole. RESULTS: Among 467 study participants, 67 (14.4%; 95% confidence interval, 11.3-17.5) were diagnosed with trichomoniasis at first T. vaginalis culture. Significant risk factors for T. vaginalis infection were having an older sex partner and concurrent Neisseria gonorrhoeae infection. The incidence was 22.1 cases per 100 person-years. Among 42 participants who had a prevalent infection and returned for follow-up, 13 (31.0%) had at least one more episode of trichomoniasis. Resistance testing was completed for 78 isolates: 37 at first visit and 41 during follow-up. One (2.7%; 95% confidence interval, 0.07-14.2) of the 37 first-visit isolates was moderately resistant to metronidazole (minimal lethal concentration = 200 mug/mL). Of the 41 follow-up visit isolates, 1 was moderately resistant to metronidazole and 2 had borderline resistance (minimal lethal concentration = 50 mug/mL). The prevalence of tinidazole resistance was 0% (0.0%-9.5%). CONCLUSION: The study population had high prevalence and incidence of trichomoniasis. The prevalence of antibiotic-resistant T. vaginalis among female adolescents was low. |
Chlamydia prevalence among women and men entering the National Job Training Program: United States, 2003-2007
Satterwhite CL , Tian LH , Braxton J , Weinstock H . Sex Transm Dis 2009 37 (2) 63-7 OBJECTIVE: To analyze 5-year prevalence trends in Chlamydia trachomatis infections among high-risk young men and women aged 16 to 24 years entering the National Job Training Program, where universal screening is required. METHODS: Entrance exams conducted in over 100 National Job Training Program centers from 2003 to 2007 were considered. Women provided cervical specimens tested using either a DNA hybridization probe (PACE 2, Gen-Probe, San Diego, CA) or a strand displacement amplification test (SDA, BD ProbeTec ET, Becton-Dickinson, Sparks, MD). In the absence of a pelvic exam, urine specimens were tested using SDA. PACE 2 testing was performed predominately from 2002 to 2005; from 2005 to 2007, SDA was used. All male testing was conducted using SDA on urine specimens. Chlamydia prevalence trends were assessed for women and men, using logistic regression models. Adjusted odds ratios (AOR), 95% confidence intervals (CI), and P-values were calculated. RESULTS: Approximately 15,000 women and 30,000 men were screened annually for chlamydia. Among both sexes, adjusted prevalence declined significantly from 2003 to 2007. In 2003, crude prevalence among women was 9.9%; in 2007, prevalence was 13.7%. However, after controlling for covariates, including increasingly sensitive tests, the model indicated a significant declining prevalence trend (AOR: 0.95, CI: 0.93-0.97, 4.6% decrease in odds per year). Among men, crude prevalence in 2003 was 8.4%; in 2007, prevalence was 8.3%; after controlling for possible confounding, a significant decline in prevalence was also detected (AOR: 0.98, CI: 0.96-0.99, 1.9% decrease in odds per year). CONCLUSIONS: In a relatively stable, high-risk population of young women and men, adjusted chlamydia prevalence declined from 2003 to 2007. Test technology plays a critical role in interpreting rates and should be considered whenever chlamydia rates are examined. |
