Abstract
BACKGROUND Prompt and appropriate treatment of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) is critical to prevent transmission and serious sequelae. The objectives were to determine the prevalence of CT/NG treatment completion and identify demographic, behavioral, and clinical factors associated with treatment completion at sexual health clinics in Baltimore City, Maryland. METHODS Electronic health record data from patients diagnosed with CT/NG during 2018-2019 were analyzed. Treatment completion was defined as documentation of Centers for Disease Control and Prevention-recommended treatment ≤30 days after testing. Regression was used to assess differences in treatment completion across groups; analyses were stratified by birth sex. RESULTS Most of the 2426 male (86%) and 754 (72%) female patients diagnosed with CT/NG completed treatment in ≤30 days; 74% of male and 36% of female patients were treated same-day. Among 890 male patients not treated same-day, treatment completion was associated with other same-day antimicrobial treatments (adjusted prevalence ratio, 0.76 [95% confidence interval, 0.61-0.94]), longer test processing times (≥10 days; 0.78 [0.65-0.95]) infection at multiple anatomic sites (1.49 [1.25-1.76]), and patients with previous clinic visits (1.16 [1.03-1.31]). Among 483 female patients not treated same-day, treatment completion was associated with diagnosis year (2019 vs. 2018; 1.23 [1.05-1.43]) and residential addresses 2 to 5 miles (vs. <2 miles) from clinic (1.25 [1.02-1.53]). Demographic and behavioral characteristics were not associated with treatment completion. CONCLUSIONS Substantial proportions of male and female sexual health clinic patients did not complete treatment. Our findings underscore the need for implementation of highly sensitive and specific point-of-care (POC) CT/NG testing to improve treatment completion in this setting.

Characteristics of Reported Gonorrhea Diagnoses During The COVID-19 Pandemic Compared With Pre-COVID-19 Pandemic, Baltimore City, Maryland. Sex Transm Dis 2023; 50:215-223. [PMID: 36473236 PMCID: PMC10009801 DOI: 10.1097/olq.0000000000001750] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2022] [Accepted: 11/28/2022] [Indexed: 12/12/2022]
Abstract
BACKGROUND Sexual health service disruptions due to COVID-19 mitigation measures may have decreased gonorrhea screening and biased case-ascertainment toward symptomatic individuals. We assessed changes in reported symptoms and other characteristics among reported gonorrhea cases during pandemic versus prepandemic periods in 1 city with persistent gonorrhea transmission. METHODS Enhanced surveillance data collected on a random sample of gonorrhea cases reported to the Baltimore City Health Department between March 2018 and September 2021 was used. Logistic regression assessed differences in case characteristics by diagnosis period (during pandemic: March 2020-September 2021; prepandemic: March 2018-September 2019). RESULTS Analyses included 2750 (1090 during pandemic, 1660 prepandemic) gonorrhea cases, representing 11,904 reported cases. During pandemic versus prepandemic, proportionally fewer cases were reported by sexual health clinics (8.8% vs 23.2%), and more frequently reported by emergency departments/urgent care centers (23.3% vs 11.9%). Adjusting for diagnosing provider, fewer cases who were men with urethral infections (adjusted odds ratio [aOR], 0.65; 95% confidence interval [CI], 0.55-0.77), aged <18 years (aOR, 0.64; 95% CI, 0.47-0.89), and women (aOR, 0.84; 95% CI, 0.71-0.99) were reported, and cases with insurance (aOR, 1.85; 95% CI, 1.40-2.45), living with human immunodeficiency virus (aOR, 1.43; 95% CI, 1.12-1.83), or recent (≤12 months) gonorrhea history (aOR, 1.25; 95% CI, 1.02-1.53) were more frequently reported during pandemic versus prepandemic. Reported symptoms and same-day/empiric treatment did not differ across periods. CONCLUSIONS We observed no changes in reported symptoms among cases diagnosed during pandemic versus prepandemic. Increased frequency of reported diagnoses who were insured, living with human immunodeficiency virus, or with recent gonorrhea history are suggestive of differences in care access and care-seeking behaviors among populations with high gonorrhea transmission during the pandemic.

Added Value of Extragenital Sexually Transmitted Infection Testing in "IWantTheKit" Program Users. Sex Transm Dis 2023; 50:138-143. [PMID: 36729630 PMCID: PMC10104591 DOI: 10.1097/olq.0000000000001743] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 02/03/2023]
Abstract
BACKGROUND The 2021 Centers for Disease Control and Prevention sexually transmitted infection treatment guidelines recommend extragenital testing for gonorrhea and chlamydia in men who have sex with men and for women based on reported behaviors and exposures. The "IWantTheKit (IWTK)" program is a free online platform for specimen self-collection and mail-in for combined chlamydia/gonorrhea testing. We sought to assess the additional diagnostic value of extragenital testing compared with genital testing only for chlamydia/gonorrhea and determine factors associated with a positive extragenital test result among IWTK users. METHODS From August 2013 to January 2022, 7612 unique IWTK users returned swabs for testing; 3407 (45%) users requested both genital and extragenital tests and were included in this analysis. Descriptive statistics were summarized for demographic characteristics, reported behaviors, and genital and extragenital test results, and data were stratified by gender and age group. A logistic regression model was used to estimate associations between factors and extragenital sexually transmitted infection positivity. RESULTS Chlamydia positivity rates were 4.7%, 2.4%, and 1.5% at genital, extragenital, and both sites, respectively; for gonorrhea, 0.4%, 1.1%, and 0.4% were positive at those sites, respectively. Among women, age 25 years and younger was significantly associated with extragenital chlamydia (odds ratio [OR], 4.0; P = 0.010). Being in high-risk quiz score group was associated with extragenital chlamydia (OR, 2.6; P = 0.005) and extragenital gonorrhea in men and women (OR, 8.5; P = 0.005). CONCLUSIONS Extragenital testing detected additional chlamydia and gonorrhea cases in the IWTK user population that would have been missed by genital-only testing, especially for women younger than 25 years and people reported to be at high risk.

Desires for Individual- and Interpersonal-Level Patient Portal Use for HIV Prevention Among Urban Sexual Minority Men: Cross-sectional Study. JMIR Form Res 2023; 7:e43550. [PMID: 36826983 PMCID: PMC9994643 DOI: 10.2196/43550] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2022] [Revised: 12/05/2022] [Accepted: 12/08/2022] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND Gay, bisexual, and other sexual minority men have expressed the acceptability of patient portals as tools for supporting HIV prevention behaviors, including facilitating disclosure of HIV and other sexually transmitted infection (STI/HIV) laboratory test results to sex partners. However, these studies, in which Black or African American sexual minority men were undersampled, failed to determine the relationship of reported history of discussing HIV results with sex partners and anticipated willingness to disclose web-based STI/HIV test results using a patient portal. OBJECTIVE Among a sample of predominantly Black sexual minority men, this study aimed to (1) determine preferences for patient portal use for HIV prevention and (2) test the associations between reported history of discussing HIV results and anticipated willingness to disclose web-based STI/HIV test results with most recent main and nonmain partners using patient portals. METHODS Data come from audio-computer self-assisted interview survey data collected during the 3-month visit of a longitudinal cohort study. Univariate analysis assessed patient portal preferences by measuring the valuation rankings of several portal features. Multiple Poisson regression models with robust error variance determined the associations between history of discussing HIV results and willingness to disclose those results using web-based portals by partner type, and to examine criterion validity of the enhancing dyadic communication (EDC) scale to anticipated willingness. RESULTS Of the 245 participants, 71% (n=174) were Black and 22% (n=53) were White. Most participants indicated a willingness to share web-based STI/HIV test results with their most recent main partner. Slightly fewer, nonetheless a majority, indicated a willingness to share web-based test results with their most recent nonmain partner. All but 2 patient portal features were valued as high or moderately high priority by >80% of participants. Specifically, tools to help manage HIV (n=183, 75%) and information about pre- and postexposure prophylaxis (both 71%, n=173 and n=175, respectively) were the top-valuated features to include in patient portals for HIV prevention. Discussing HIV test results was significantly associated with increased prevalence of willingness to disclose web-based test results with main (adjusted prevalence ratio [aPR] 1.46, 95% CI 1.21-1.75) and nonmain partners (aPR 1.54, 95% CI 1.23-1.93). CONCLUSIONS Our findings indicate what features Black sexual minority men envision may be included in the patient portal's design to optimize HIV prevention, further supporting the criterion validity of the EDC scale. Efforts should be made to support Black sexual minority men's willingness to disclose STI/HIV testing history and status with partners overall as it is associated significantly with a willingness to disclose testing results digitally via patient portals. Future studies should consider discussion behaviors regarding past HIV test results with partners when tailoring interventions that leverage patient portals in disclosure events.

Abstract
BACKGROUND Despite substantial investments in ending the HIV epidemic, disparities in HIV care persist, and there is an urgent need to evaluate novel and scalable approaches to improving HIV care engagement and viral suppression in real-world settings. OBJECTIVE This paper aims to describe a study protocol for a pragmatic type II hybrid effectiveness-implementation randomized controlled trial comparing existing standard of care clinic HIV linkage, adherence, and retention (LAR) protocols to a mobile health (mHealth)-enhanced linkage, adherence, and retention (mLAR) intervention. METHODS The study will enroll 450 participants from clinics in Baltimore City. Eligibility criteria include being ≥18 years of age, having a new HIV diagnosis or being HIV-positive and out of care, or being HIV-positive and deemed by clinic staff as someone who could benefit from linkage and retention services. Participants randomized to the intervention receive mHealth-supported patient navigation for 12 months. Participants in the control group receive the referring clinic's standard of care patient support. The primary outcome is HIV virologic suppression at 12 months. A subset of participants will be interviewed at 12 months to learn about their HIV care experiences and, for those in the intervention arm, their experiences with the mLAR intervention. This protocol was developed in collaboration with the Baltimore City Health Department (BCHD) and the Maryland Department of Health (MDH) and with input from a community advisory board. RESULTS Enrollment began on February 25, 2020. As of August 11, 2022, 411 of the 450 target participants had been enrolled. CONCLUSIONS Pragmatic implementation science trials designed with input from key stakeholders, including health departments and community members, can help evaluate the evidence for mHealth interventions to reduce HIV health disparities.

Abstract
Urban Black men who have sex with men (MSM) bear a disproportionate burden of HIV and syphilis in the U.S. Experiences of enacted sexual minority stigma and psychological distress among these men may be associated with HIV/STI sexual and drug risk behaviors. The objective was to determine the associations between enacted sexual minority stigma, psychological distress, and sexual and drug risk behaviors. In an urban prospective cohort study, survey measures assessed past 3-month exposure to enacted sexual minority stigma, psychological distress, and sexual and drug risk behaviors. Multivariable logistic regression models were utilized for hypothesis testing. The Black MSM (N = 140) reported the following: 22.1% experiences of enacted sexual minority stigma, 39% high levels of psychological distress, 48.6% > 1 sex partner, 8.6% transactional sex, and 6% injection drug use (IDU). In models adjusted for age and education, enacted sexual minority stigma significantly increased the odds of reporting > 1 sex partner, transactional sex, and IDU. Adjusting additionally for homelessness, the association between enacted sexual minority stigma and transactional sex remained significant. Adding psychological distress to this model showed a significant association between psychological distress and transactional sex, while the association was no longer significant for transactional sex. These findings highlight some of the complex psycho-social relationships that may be associated with sexual and drug risk behaviors among Black MSM placing them at increased risk for HIV and syphilis.

Abstract
Background. Although research dissemination to participants and community stakeholders is a fundamental component of translational research, it rarely occurs. The objective of this study was to create a community-led, theory-based dissemination plan to engage local Black sexual minority men in an active dissemination process throughout a sexual health research study. Method. Seven focus groups (N = 38) were conducted with Black, cisgender sexual minority men aged 18 to 45 years. Findings were analyzed through thematic content analysis guided by McGuire's persuasive communication theory. Findings were used to draft a dissemination plan, which was then reviewed and edited by the study's community advisory board (CAB). The plan continues to be updated in response to community needs through CAB discussions. Results. Participants preferred messages concerning syphilis and other health concerns as well as information on local resources. Preferred sources included researchers working with trusted community organizations and leaders. Preferred channels included community events and social media, implemented with consistency. CAB feedback included expanding the target audience of dissemination efforts as well as the development of ideas for channels (i.e., events) and sources (i.e., community organizations and leaders). Additional revisions occurred in response to the COVID-19 pandemic. Conclusion. Given the continued lack of research dissemination to participant and community stakeholders, the process of developing a community-led, theory-based dissemination plan may benefit and help guide researchers to adopt this practice. It is critical that participant and community stakeholder dissemination become more highly prioritized as we strive for public health improvements and the elimination of health disparities.

Abstract
Background The Baltimore City Health Department (BCHD) began community-based COVID-19 testing in response to the pandemic on April 21, 2020. The purpose was to provide access to COVID-19 testing to underserved communities. BCHD designed the program to accommodate transportation limitations, limited-access to internet and phones, and non-English speakers. BCHD has continued hosting up to five community-based testing sites per week. This analysis examines the test results of BCHD’s COVID-19 community-based testing program to date. Methods Patients completed an intake form, which included demographic information, at the testing event, prior to providing their specimen for COVID-19 testing. For this analysis, patient demographics and test results were analyzed using REDCap software. Results Total test volume for year 2020 (4/21/2020 -12/30/2020) was 15,839, year 2021 (1/5/2021- 12/30/2021) was 13,087, and year 2022 (1/4/2022 - 4/1/2022) was 2,261. Average percent positivity for year 2020 was 9%, year 2021 was 7%, and year 2022 to date was 6%. Patient ethnicity was Non-Hispanic 85.5%, Hispanic 13.5%, and Did not respond/Don’t know 1.0%. Race was Black or African America 61.1%, White 25.0%, Asian 2.8%, American Indian/Alaska Native 0.1%, Native Hawaiian or Other Pacific Islander 0.1%, and Unknown 10.7%. Total positive COVID-19 results among Black/African Americans in 2020, 2021, and 2022 respectively were 1567 (12.8%), 1177 (15.1%), and 218 (22.1%). Total positive COVID-19 results among White in 2020, 2021, and 2022 respectively were 541 (10.1%), 441 (12.1%), and 60 (15.1%) respectively. Total positive COVID-19 results among Asians in 2020, 2021, and 2022 were 63 (20.9%), 47 (11.0%), and 4 (25.5%) respectively. Total positive COVID-19 results among Native Hawaiian or Other Pacific Islander in 2020, 2021, and 2022 respectively were 4 (16.7%), 4 (20.0%), and 2 (0.0%) respectively. Total positive COVID-19 results among American Indian/Alaskan in 2020, 2021, and 2022 were 3 (13.6%), 1 (7.1%), and 2 (66.7%) respectively. Conclusion BCHD’s community-based testing program has completed over 31,000 tests to date. COVID-19 percent positivity among patients showed a decline across the three years.

Abstract
INTRODUCTION People who use drugs (PWUD) face a multitude of barriers to accessing healthcare and other services. Mobile health clinics (MHC) are an innovative, cost-effective health care delivery approach that increases healthcare access to vulnerable populations and medically underserved areas. There is limited understanding, however, of how PWUD perceive and experience MHCs. METHODS Semi-structured interviews were conducted with 31 PWUD - 16 who had received care (clients) on an MHC (The Spot) and 15 who had not (non-clients) - to explore their perceptions and utilization of an MHC partnered with a mobile syringe services program in Baltimore, Maryland. Data analysis of the text was conducted using an iterative thematic constant comparison process informed by grounded theory. RESULTS Clients and non-clients, once aware of the MHC, had positive perceptions of The Spot and its benefits for their individual health as well as for the wellbeing of their community. These sentiments among clients were largely driven by access to low-barrier buprenorphine and service delivery without stigma around drug use. However, lack of general awareness of the spot and specific service offering were barriers to its use among non-clients. DISCUSSION MHCs provide an important opportunity to engage PWUD in healthcare and to expand buprenorphine use; however, even with accessibility near where PWUD access injection equipment, barriers to its use remain. Peer dissemination may be able to facilitate program information sharing and recruitment.KEY MESSAGESPeople who use drugs perceive a mobile health clinic in their neighbourhood as a benefit to their communities and themselves by improving access to healthcare services, providing access to low-threshold buprenorphine dispensation, and offering services without drug use stigma.People who use drugs learned about a mobile health clinic in their neighbourhood largely through word-of-mouth. As a result, people received limited information about the mobile health clinic services creating a barrier to its use.

Abstract
BACKGROUND The impact of coronavirus disease 2019 (COVID-19) mitigation measures on sexually transmitted infection (STI) transmission and racial disparities remains unknown. Our objectives were to compare sex and drug risk behaviors, access to sexual health services, and STI positivity overall and by race during the COVID-19 pandemic compared with pre-pandemic among urban sexual minority men (MSM). METHODS Sexually active MSM aged 18-45 years were administered a behavioral survey and STI testing every 3-months. Participants who completed at least 1 during-pandemic (April 2020-December 2020) and 1 pre-pandemic study visit (before 13 March 2020) that occurred less than 6 months apart were included. Regression models were used to compare during- and pre-pandemic visit outcomes. RESULTS Overall, among 231 MSM, reports of more than 3 sex partners declined(pandemic-1: adjusted prevalence ratio 0.68; 95% confidence interval: .54-.86; pandemic-2: 0.65, .51-.84; pandemic-3: 0.57, .43-.75), substance use decreased (pandemic-1: 0.75, .61-.75; pandemic-2: 0.62, .50-.78; pandemic-3: 0.61, .47-.80), and human immunodeficiency virus/preexposure prophylaxis care engagement (pandemic-1: 1.20, 1.07-1.34; pandemic-2: 1.24, 1.11-1.39; pandemic-3: 1.30, 1.16-1.47) increased. STI testing decreased (pandemic-1: 0.68, .57-.81; pandemic-2: 0.78, .67-.92), then rebounded (pandemic-3: 1.01, .87-1.18). Nei-ther Chlamydia (pandemic-2: 1.62, .75-3.46; pandemic-3: 1.13, .24-1.27) nor gonorrhea (pandemic-2: 0.87, .46 1.62; pandemic-3: 0.56, .24-1.27) positivity significantly changed during vs pre-pandemic. Trends were mostly similar among Black vs. non-Black MSM. CONCLUSIONS We observed sustained decreases in STI risk behaviors but minimal change in STI positivity during compared with pre-pandemic. Our findings underscore the need for novel STI prevention strategies that can be delivered without in-person interactions.

Abstract
BACKGROUND Black men who have sex with men (MSM) carry the greatest burden of new HIV diagnoses in the United States. Ending the HIV epidemic requires strategic, culturally specific approaches to target factors contributing to persistent HIV disparities. SETTING Safe Spaces 4 Sexual Health (SS4SH), a community-informed HIV/sexually transmitted infection (STI) testing strategy combining mobile van testing with online outreach, was implemented over a 14-month period from 2018 to 2019 in Baltimore, MD. METHODS We evaluated the reach of MSM at high risk with high acquisition or transmission risk by SS4SH mobile van combined with online outreach as compared with the Baltimore City Health Department's venue-based mobile van (with no online outreach) operating during the same period based on the following HIV/STI testing outcome measures: (1) number of MSM HIV or STI tested, (2) new HIV diagnosis rate, (3) percent with new syphilis diagnosis, (4) percent at high risk for HIV acquisition, and (5) percent people living with HIV at high risk for transmission. RESULTS Over a 14-month period, SS4SH HIV/STI tested 151 MSM. Of these, 74% were Black and the mean age was 34 (SD = 10, range = 19-68). Seven percent (10/148) were new HIV diagnoses, and 10% (13/130) were diagnosed with syphilis. The Baltimore City Health Department's venue-based mobile van strategy yielded 53% (231) more MSM (71% Black, mean age 38, SD = 14, range = 15-74), but the HIV/syphilis positivity rate was significantly lower: 0.5% new HIV diagnosis rate (P < 0.001) and 0.5% with syphilis diagnosis (P < 0.001). CONCLUSIONS Our findings suggest SS4SH combing online outreach with mobile van testing may be more effective at reaching high-risk Black MSM than venue-based mobile testing.

HIV Transmission Potential and Sex Partner Concurrency: Evidence for Racial Disparities in HIV Risk Among Gay and Bisexual Men (MSM). AIDS Behav 2022; 26:709-718.

Abstract
We determined whether racial disparities in HIV infection among gay and bisexual men (MSM) may be partially explained by racial differences in the HIV transmission potential (i.e. mixing of people living with HIV and people not living with HIV or of unknown HIV serostatus) and density (i.e. sex partner concurrency) of sexual networks. Data included a behavioral survey, testing for HIV, and an egocentric sexual network survey. Mixed effects logistic regressions were used for hypothesis testing. Black (vs. non-Black) MSM were more likely to not know their partner's HIV serostatus (21.8% vs. 9.6%). Similar proportions reported sex partner concurrency (67.1% vs. 68.0%). In adjusted analyses, among Black MSM, sex partner concurrency significantly increased the odds of an HIV transmission potential partnership (TPP), and this association was not significant among non-Black indexes. The association between an HIV TPP and sex partner concurrency may help explain persistent racial disparities in HIV prevalence.

#ProjectPresence: Highlighting black LGBTQ persons and communities to reduce stigma: A program evaluation. EVALUATION AND PROGRAM PLANNING 2022; 90:101978. [PMID: 34275640 DOI: 10.1016/j.evalprogplan.2021.101978] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/11/2020] [Revised: 05/20/2021] [Accepted: 07/06/2021] [Indexed: 06/13/2023]
Abstract
Etiologies of HIV disparities are multifaceted; anti-LGBTQ stigma and social marginalization are contributory factors. A city health department developed a program, #ProjectPresence, exhibiting professional photos of Black LGBTQ persons in public spaces. An academic partner explored the relationship of the program to visibility, anti-LGBTQ stigma and social marginalization of Black LGBTQ persons, i.e. models, directly involved in the program and their perceptions of these relationships more broadly for community members. Brief self-administered surveys and semi-structured, in-depth interviews with #ProjectPresence models (n = 15) were conducted after the program to gather their experiences before, during and after the program. Descriptive analyses of survey responses were conducted using Stata 15.1. Interviews were audio-recorded, transcribed and analyzed in NVivo10 using categorical analysis. Surveys indicated prevalent experiences of enacted stigma (73 %) and perceptions of poor local acceptance of LGBTQ people (53 %). Interviews suggested that the program may have influenced positive individual- and community-level changes by increasing visibility of LGBTQ communities and improving acceptance among non-LGBTQ persons, inspiring personal growth and self-acceptance among models, and providing opportunities to foster new connections among LGBTQ subpopulations. Our findings suggest similar programs may present promising approaches for the reduction of stigma and social marginalization affecting LGBTQ persons and communities.

Storytelling to improve healthcare worker understanding, beliefs, and practices related to LGBTQ + patients: A program evaluation. EVALUATION AND PROGRAM PLANNING 2022; 90:101979. [PMID: 34275639 DOI: 10.1016/j.evalprogplan.2021.101979] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/11/2020] [Revised: 01/22/2021] [Accepted: 06/17/2021] [Indexed: 06/13/2023]
Abstract
LGBTQ + persons experience significant health inequities and medical distrust resulting from anti-LGBTQ + bias or cultural incompetence from health care workers (HCW). This program evaluation examined whether storytelling events where LGBTQ + persons shared personal and patient experiences changed HCW understanding, beliefs, and practices related to LGBTQ + patients. Five storytelling events, held biannually in Baltimore, Maryland from 2016 to 2018, were evaluated using post-event surveys, written reflections/notes during the event, and a survey of HCW in a citywide care collaborative focused on HIV prevention and treatment for LGBTQ + persons that did and did not attend a storytelling event. We analyzed surveys to measure differences in understanding, beliefs and practices and used thematic qualitative analysis of written reflections/notes from the storytelling events. 416 persons attended storytelling events; 124(30 %) completed post-event surveys and 449 written reflections/notes were collected. 56 HCW completed post-event surveys; 49(87.5 %) strongly agreed/agreed they better understood LGBTQ + patients. Emergent themes from the 43 HCW written reflections/notes included improved understanding and new approaches for engaging LGBTQ + patients. Among HCW survey respondents (n = 111), attending an event was associated with significant differences in beliefs (p = 0.024) and practices (p = 0.000) related to LGBTQ + patients. Storytelling events may serve as effective tools for increasing HCW's understanding, beliefs and practices. This strategy may ultimately help decrease anti-LGBTQ + bias, reduce medical distrust and lower barriers to HIV prevention/treatment for LGBTQ + persons.

Mobile low-threshold buprenorphine integrated with infectious disease services. J Subst Abuse Treat 2022; 133:108553. [PMID: 34238629 PMCID: PMC8702567 DOI: 10.1016/j.jsat.2021.108553] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2021] [Revised: 05/24/2021] [Accepted: 06/13/2021] [Indexed: 02/03/2023]
Abstract
INTRODUCTION In 2018, the Baltimore City Health Department launched a mobile clinic called Healthcare on The Spot, which offers low-threshold buprenorphine services integrated with health care services to meet the needs of people who use drugs. In addition to buprenorphine management, The Spot offers testing and treatment for hepatitis C, sexually transmitted infections, and HIV, as well as pre-exposure prophylaxis for HIV, wound care, vaccinations, naloxone distribution, and case management. METHODS AND MATERIALS This cohort analysis includes clinical service data from the first 15 months of The Spot mobile clinic, from September 4, 2018, to November 23, 2019. The Spot co-located with the Baltimore syringe services program in five locations across the city. Descriptive data are provided for patient demographics and services provided, as well as percent of patients retained in buprenorphine treatment at one and three months. Logistic regression identified factors associated with retention at three months. RESULTS The Spot mobile clinic provided services to 569 individuals from September 4, 2018, to November 23, 2019, including prescribing buprenorphine to 73.8% and testing to more than 70% for at least one infectious disease. Patients receiving a prescription for buprenorphine were more likely to be tested for HIV, hepatitis C, and sexually transmitted infections, as well as receive treatment for hepatitis C and preventive services including vaccination and naloxone distribution. The Spot initiated HIV treatment for four patients and HIV pre-exposure prophylaxis for twelve patients. More than 32% of patients had hepatitis C; nineteen of these patients initiated treatment for hepatitis C with eight having a documented cure. Buprenorphine treatment retention was 56.0% at one month and 26.2% at three months. Patients who were Black or receiving treatment for hepatitis C were more likely to be retained in buprenorphine treatment at three months. CONCLUSIONS Increasing access to integrated medical services and drug treatment through low-threshold, community-based models of care can be an effective tool for addressing the effects of drug use.

Abstract
Abstract
The COVID-19 pandemic left an unprecedented impact on the general public health, resulting in hundreds of thousands of deaths in the US alone. Nationwide testing plans were initiated, with drive-through being the currently dominant testing approach, which, however, exhausts personal protective equipment supplies, and is unfriendly to individuals not owning a vehicle. Walk-up positive pressure testing booths are a safe alternative, whereby a health care provider situated on the inside of an enclosed and positively pressurized booth swabs a patient on the outside through chemical resistant gloves. The booths, however, are too prohibitively priced on the market to allow for nationwide deployment. To mitigate this, we present in this paper a safe, accessible, mobile and affordable design of positive-pressure COVID-19 testing booths. The booths have successfully passed the CDC and HICPAC pressure, air exchange, and air quality requirements for positive-pressure rooms, following the guidelines for environmental infection control in health care facilities. The booths are manufactured using primarily off-the-shelf components from US vendors with minimized customization, and the final bill of materials does not surpass USD 3,900. Since August 2019, five booths were deployed and used at the Johns Hopkins University School of Nursing, Baltimore City Health Department, and two community health centers in Baltimore. No health care provider was infected when using our booths, which have shown to facilitate walk-up testing with decreased PPE consumption, reduced risk of infection, and enhanced accessibility to lower-income communities and non-drivers.

Abstract
Latinxs in the U.S. are disproportionately affected by HIV and more likely to have delayed diagnosis than their non-Latinx peers. We developed and implemented Sólo Se Vive Una Vez (You Only Live Once), the first Spanish-language campaign aimed at improving HIV testing and prevention among Latinx immigrants in Baltimore, Maryland. Sólo Se Vive Una Vez featured a website (www.solovive.org) and social marketing campaign promoting free HIV testing through the Baltimore City Health Department (BCHD) clinic and Latinx outreach team. The campaign was not associated with a change in the overall number of Latinxs obtaining HIV testing. However, Latinx HIV testers who reported being exposed to the campaign had significantly higher rates of high-risk sexual behaviors, mean number of sexual partners, and substance use. The campaign was also associated with increased PrEP referrals through the BCHD Latinx outreach team.

Reaching Those Most at Risk for HIV Acquisition: Evaluating Racial/Ethnic Disparities in the Preexposure Prophylaxis Care Continuum in Baltimore City, Maryland. J Acquir Immune Defic Syndr 2021; 87:1145-1153. [PMID: 33883471 PMCID: PMC9306005 DOI: 10.1097/qai.0000000000002712] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2020] [Accepted: 02/25/2021] [Indexed: 11/26/2022]
Abstract
BACKGROUND Reducing HIV incidence requires addressing persistent racial/ethnic disparities in HIV burden. Our goal was to evaluate preexposure prophylaxis (PrEP) delivery, overall and relative to community need, among 7 clinical sites participating in a health department-led demonstration project to increase PrEP in Baltimore city, MD. METHODS PrEP care continuum stages (screened, indicated, referred, linked, evaluated, prescribed) were examined among HIV-negative individuals receiving services at participating sites between September 30, 2015 and September 29, 2019. Community need was defined using information on new HIV diagnoses (2016-2018). Differences in care continuum progression by demographics/priority population and comparison of demographic compositions between care continuum stages and new HIV diagnoses were examined using modified Poisson regression and χ2 tests, respectively. RESULTS Among 25,886 PrEP-screened individuals, the majority were non-Hispanic (NH) black (81.1%, n = 20,998), cisgender male (61.1%, n = 15,825), and heterosexual (86.7%, n = 22,452). Overall, 31.1% (n = 8063) were PrEP-indicated; among whom, 56.8% (n = 4578), 15.6% (n = 1250), 10.8% (n = 868), and 9.0% (n = 722) were PrEP-referred, linked, evaluated, and prescribed, respectively. Among 2870 men who have sex with men (MSM), 18.7% (n = 538) were PrEP-prescribed. Across all groups, the highest attrition was between PrEP-referred and PrEP-linked. NH-black race (vs. NH-white) was independently associated with lower likelihood of PrEP prescription (aPR, 0.89; 95% confidence interval, 0.81 to 0.98 controlling for age/gender). Relative to the demographic composition of new HIV diagnoses, fewer NH-blacks (80.2% vs. 54.3%) and more NH-whites (10.7% vs. 30.3%) and MSM were PrEP prescribed (55.2% vs. 74.5%). CONCLUSIONS This project showed promise delivering PrEP referrals and prescriptions overall and to MSM. Substantial improvement is needed to improve linkage overall and to decrease disparities in PrEP prescriptions among NH-blacks. Future work should focus on addressing service gaps that hinder PrEP utilization.

Abstract
BACKGROUND Human immunodeficiency virus pre-exposure prophylaxis (PrEP) clinical guidelines recommend men who have sex with men (MSM) PrEP users be screened biannually for syphilis and gonorrhea/chlamydia at all anatomic sites. We sought to determine the proportion screened and positive by STI and anatomic site at PrEP initiation and PrEP-care visits and patient-level characteristics associated with screening among MSM PrEP users in Baltimore City, Maryland. METHODS Medical records among MSM initiating PrEP between 30 September 2015 and 31 March 2018 were abstracted. STI screening (syphilis and gonorrhea/chlamydia at all anatomic sites) and positivity at PrEP visits ≤12 months following initiation were calculated. Poisson regression with cluster robust SEs was used to assess associations with STI screening. RESULTS Among 290 MSM initiating PrEP, 43.1% (n = 125) were screened per guidelines at PrEP initiation; 79.3% (230), 69.3% (201), 55.9% (162), and 69.3% (201) were screened for syphilis, urogenital, rectal, and oropharyngeal gonorrhea/chlamydia, respectively. Positivity among those screened was syphilis, 7.8% (n = 18/230); gonorrhea, 5.0% urogenital (10/201), 11.1% rectal (18/162), and 7.5% oropharyngeal (15/201); chlamydia, 5.0% urogenital (10/201), 11.7% rectal (19/162), and 1.5% oropharyngeal (3/201). Reported anal and oral sex (vs neither) was independently associated with STI screening (aPR, 2.11; 1.05-4.27) at PrEP initiation. At biannual PrEP-care visits, STI screening was lower and syphilis and rectal gonorrhea/chlamydia positivity was higher. CONCLUSIONS Observed STI screening levels and disease burden suggest the effectiveness of STI screening in PrEP care for STI prevention may be limited. Our results suggest providers may be offering screening based on sexual practices; clarification of STI screening guidelines for PrEP users is needed.

Abstract
The goal of this study was to assess awareness of, interest in, and sources of knowledge about pre-exposure prophylaxis (PrEP) among 1,464 HIV-uninfected patients from public STD clinics in Baltimore. Logistic regression analyses were conducted to examine factors associated with PrEP awareness and interest. Results suggest PrEP awareness and interest in knowing more about PrEP was highest among men who reported sex with men or with both men and women. White patients were more likely to be aware of PrEP than African American patients, and those reporting consistent condom use were more likely to have heard about PrEP than those who never used condoms. The major source of knowledge about PrEP was health care providers. Findings can inform future prioritization of locally targeted PrEP programs to enhance access to and uptake of PrEP among those most at risk for HIV transmission.

Abstract
BACKGROUND Individuals diagnosed with gonorrhea are at elevated risk for HIV. Per US Centers for Disease Control and Prevention guideline, individuals being evaluated for gonorrhea should be screened for HIV concurrently. There is limited information on HIV screening among gonorrhea-diagnosed individuals across different health care settings. Our objective was to identify potential gaps in HIV screening among gonorrhea-diagnosed individuals in Baltimore City, Maryland. METHODS We used Sexually Transmitted Disease Surveillance Network project data collected on a random sample of all gonorrhea diagnoses reported to the health department between April 2015 and April 2019. Individuals with known HIV diagnoses were excluded. HIV screening was confirmed through surveys administered to the gonorrhea-diagnosing provider. HIV screening across groups was assessed using Poisson regression models with robust SEs. We examined those with and without recent (≤12 months) sexually transmitted infection (STI) history separately. RESULTS Among 2830 gonorrhea-diagnosed individuals with completed Sexually Transmitted Disease Surveillance Network provider surveys, less than half (35.2% with and 44.8% without recent STI history) received concurrent HIV screening. HIV screening was 73% less prevalent among those diagnosed in emergency departments/urgent care centers/hospitals versus sexual health clinics (with and without recent STI history: adjusted prevalence ratio, 0.27 [95% confidence interval, 0.19-0.39]; adjusted prevalence ratio, 0.27 [0.23-0.33]), controlling for diagnosis year, sex, race/ethnicity, age, infection site, and insurance. CONCLUSIONS Our findings suggest a considerable gap in HIV screening among individuals at elevated risk for HIV acquisition in Baltimore City, particularly among those diagnosed in emergency departments/urgent care centers/hospital settings. Future work should focus on identifying provider-level barriers to concurrent HIV/STI screening to inform provider education programs.

Abstract
Syphilis and HIV among gay, bisexual and other men who have sex with men (MSM) are syndemic suggesting current prevention strategies are not effective. Sex partner meeting places and their networks may yield effective and optimal interventions. From 2009 to 2017, 57 unique venues were reported by > 1 MSM and 7.0% (n = 4), 21.1% (n = 12) and 71.9% (n = 41) were classified as syphilis, HIV or co-diagnosed venues, respectively. Forty-nine venues were connected in one main network component with four online, co-diagnosis venues representing 51.6% of reports and the highest degree and eigenvector centralities. In a sub-analysis during a local syphilis epidemic, the proportion of venues connected in the main component increased 38.7% (61.5% to 86.4%); suggesting increasing overlap in syphilis and HIV transmission and density of the venue network structure over time. This network analysis may identify the optimal set of venues for tailored interventions. It also suggests increasing difficulty of interrupting network transmission through fragmentation.

Abstract
Latinxs in the United States are disproportionately affected by HIV and present with more advanced disease than their non-Latinx peers, due to numerous barriers to care including HIV stigma. We describe the adaptation, implementation, and reach of Sólo Se Vive Una Vez (You Only Live Once), Baltimore's first social marketing campaign promoting HIV screening among Spanish-speaking Latinxs. The 6-month campaign promoted free HIV testing by addressing HIV stigma. The campaign included a website, a social marketing campaign, community outreach events, and advertisements via radio, billboards, local partners, and buses. During the campaign, there were 9,784 unique website users, and ads were served to over 84,592 people on social media platforms. Among Latinx HIV testers at the Baltimore City Health Department, 31.6% reported having seen or heard of Sólo Se Vive Una Vez and 25.3% of Latinx HIV testers reported that the campaign influenced them to get tested.

Abstract
Abstract
Background
New conduction abnormalities necessitating pacemaker implantation (PMI) is a common occurrence after TAVR. There is an increased rate of PMI in the those receiving the most contemporary implanted valve, the Edwards Sapien-3 (S3), compared to prior generation balloon expandable valves. We previously described predictors of PMI in a large cohort. Herein we sought to validate these predictors of PMI in a subsequent validation cohort.
Methods
We evaluated all patients undergoing first time elective TAVR with S3 at our institution (n=326). We developed a risk score based on a predictive model we have previously described. Patients received one point for each of the following: history of syncope, oversizing of the valve >16%, baseline right bundle branch block morphology, and two points for a QRS duration >115 ms. We performed regression analysis of the risk score and need for PMI. We also evaluated the performance of the risk score using ROC analysis.
Results
Thirty patients (8%) of the total cohort had need for PMI after S3 implantation. Those with PMI had a higher rate of pre-existing infra-nodal conduction system disease – including QRS duration >115ms (57% vs. 20%, p<0.001) and right bundle branch block (RBBB) morphology (47% vs. 10%, p<0.001) - as well as more frequent valve oversizing >15.7% (47% vs. 23%, p<0.01). There was no significant difference in a history of syncope (10% vs. 8%, p=0.72) between groups. The PMI risk score had an area under the curve of 0.753 on ROC analysis. The PMI risk score was significantly associated with PMI (OR 2.37; 95% CI [1.64–3.34], p<0.001).
Rate of PMI Stratified by Risk Score
Conclusions
The PMI risk score was strongly predictive of the need for PMI after implantation of the S3 valve in a large validation cohort. The PMI risk score performed well in sensitivity analysis. This PMI risk score represents a simple tool to help further risk stratify patients being considered for TAVR.

Abstract
INTRODUCTION The purpose of the study is to examine whether demand for publicly funded sexually transmitted disease clinics changed after Affordable Care Act implementation. METHODS The percentages of total incident sexually transmitted infections in Baltimore City that occurred at publicly funded sexually transmitted disease clinics were compared between the 3 years prior to and following the 2014 Medicaid and private insurance expansions. Risk factors associated with diagnosis at sexually transmitted disease clinics were identified using log binomial regression. Statistical analyses were conducted in May 2017. RESULTS Post-Affordable Care Act, the relative proportion of total sexually transmitted infection diagnoses increased among private and hospital-affiliated clinics, remained unchanged at sexually transmitted disease clinics, and decreased at federally qualified health centers and other publicly funded programs (p<0.001). Multivariable analysis controlling for age, sex, race, and ethnicity showed an overall decline in the risk of diagnosis at sexually transmitted disease clinics post-Affordable Care Act compared with prior (adjusted relative risk=0.92, 95% CI=0.89, 0.96), but the risk among black and Latino men aged <25 years persisted (relative risk=1.03, 95% CI=0.96, 1.10). CONCLUSIONS The Affordable Care Act increased access to traditional health care, reducing burden on publicly funded programs. However, demand for sexually transmitted disease clinics remains substantial among priority patients. In the healthcare reform era, sexually transmitted disease clinic funding remains critical.

Abstract
BACKGROUND The near-universal prevalence of electronic health records (EHRs) has made the utilization of clinical decision support systems (CDSS) an integral strategy for improving the value of laboratory ordering. Few studies have examined the effectiveness of nonintrusive CDSS on inpatient laboratory utilization in large academic centres. METHODS Red blood cell folate, hepatitis C virus viral loads and genotypes, and type and screens were selected for study. We incorporated the appropriate indications for these labs into text that accompanied the laboratory orders in our hospital's EHR. Providers could proceed with the order without additional clicks. An interrupted time-series analysis was performed, and the primary outcome was the rate of tests ordered on all inpatient medicine floors. RESULTS The rate of folate tests ordered per monthly admissions showed no significant level change at the time of the intervention with only a slight decrease in rate of 0.0109 (P = .07). There was a 43% decrease in the rate of hepatitis C virus tests per monthly admissions immediately after the intervention with a decrease of 0.0135 tests per monthly admissions (P = .02). The rate of type and screens orders per patient days each month had a significant downward trend by 0.114 before the intervention (P = .04) but no significant level change at the time of the intervention or significant change in rate after the intervention. DISCUSSION Our study suggests that nonintrusive CDSS should be evaluated for individual laboratory tests to ensure only effective alerts continue to be used so as to avoid increasing EHR fatigue.

Abstract
Background Acute lower respiratory tract infections (LRTI) are a frequent cause of hospitalization and mortality in South Africa; however, existing respiratory severity scores may underestimate mortality risk in HIV-infected adults in resource limited settings. A simple predictive clinical score for low-resource settings could aid healthcare providers in the management of patients hospitalized with LRTI. Methods We analyzed 1,356 LRTI hospitalizations in adults aged ≥18 years enrolled in Severe Acute Respiratory Illness (SARI) surveillance in three South African hospitals from January 2010 to December 2011. Using demographic and clinical data at admission, we evaluated potential risk factors for in-hospital mortality. We evaluated three existing respiratory severity scores, CURB-65, CRB-65, and Classification Tree Analysis (CTA) Score assessing for discrimination and calibration. We then developed a new respiratory severity score using a multivariable logistic regression model for in-hospital mortality and assigned points to risk factors based on the coefficients in the multivariable model. Finally we evaluated the model statistically using bootstrap resampling techniques. Results Of the 1,356 patients hospitalized with LRTI, 101 (7.4%) died while hospitalized. The CURB-65, CRB-65, and CTA scores had poor calibration and demonstrated low discrimination with c-statistics of 0.594, 0.548, and 0.569 respectively. Significant risk factors for in-hospital mortality included age ≥ 45 years (A), confusion on admission (C), HIV-infection (H), and serum blood urea nitrogen >7 mmol/L (U), which were used to create the seven-point ACHU clinical predictor score. In-hospital mortality, stratified by ACHU score was: score ≤1, 2.4%, score 2, 6.4%, score 3, 11.9%, and score ≥ 4, 29.3%. Final models showed good discrimination (c-statistic 0.789) and calibration (chi-square 1.6, Hosmer-Lemeshow goodness-of-fit p-value = 0.904) and discriminated well in the bootstrap sample (average optimism of 0.003). Conclusions Existing clinical predictive scores underestimated mortality in a low resource setting with a high HIV burden. The ACHU score incorporates a simple set a risk factors that can accurately stratify patients ≥18 years of age with LRTI by in-hospital mortality risk. This score can quantify in-hospital mortality risk in an HIV-endemic, resource-limited setting with limited clinical information and if used to facilitate timely treatment may improve clinical outcomes.

Do Thai Physicians Recommend Seasonal Influenza Vaccines to Pregnant Women? A Cross-Sectional Survey of Physicians' Perspectives and Practices in Thailand. PLoS One 2017; 12:e0169221. [PMID: 28099486 PMCID: PMC5242501 DOI: 10.1371/journal.pone.0169221] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2016] [Accepted: 12/13/2016] [Indexed: 11/18/2022] Open
Abstract
BACKGROUND Physicians play a major role in influencing acceptance and uptake of vaccines. However, little is known about physicians' perspectives on influenza vaccination of pregnant women in Thailand, for whom vaccine coverage is estimated at <1%. METHOD In 2013, a self-administered questionnaire on physicians' perceptions, attitudes and practices related to influenza vaccination for pregnant women was distributed to 1,134 hospitals with an antenatal care clinic (ANC) in Thailand. At each hospital, one physician working at the ANC completed the survey. Predictors of routine recommendation of influenza vaccine were analyzed utilizing log-binomial regression. RESULTS A total of 580 (51%) complete responses were received from physicians practicing at ANCs. A favorable attitude towards vaccination was expressed by 436 (75%) physicians, however only 142 (25%) reported routinely recommending influenza vaccine to pregnant women in their current practice. Physicians were more likely to recommend influenza vaccine routinely when they had more than three years of practice (prevalence ratio [PR] 1.9, 95% CI 1.2-2.3), had treated pregnant women for influenza (PR 1.8, 95% CI 1.3-2.7), perceived the influenza vaccine to be effective (moderate level: PR 1.6, 95% CI 1.1-2.4; high level: PR 1.9, 95% CI 1.3-2.9) and were aware of the Ministry of Public Health's (MOPH) recommendation of influenza vaccination in pregnancy (PR 1.3, 95% CI 1.1-1.7). Vaccine not being available, perception that policy was ambiguous and lack of awareness of MOPH recommendations were the most commonly cited barriers to routine recommendation of influenza vaccine. CONCLUSION Despite a national policy to vaccinate pregnant women for influenza, only 25% of Thai physicians working in ANCs routinely recommend vaccination. Strategies are needed to increase vaccine availability and free vaccine services, address clinician concerns over vaccine effectiveness and expand healthcare provider awareness of MOPH recommendations.

Abstract
Most influenza vaccines are generally safe, but influenza vaccines can cause rare serious adverse events. Some adverse events, such as fever and febrile seizures, are more common in children than adults. There can be differences in the safety of vaccines in different populations due to underlying differences in genetic predisposition to the adverse event. Live attenuated vaccines have not been studied adequately in children under 2 years of age to determine the risks of adverse events; more studies are needed to address this and several other priority safety issues with all influenza vaccines in children. All vaccines intended for use in children require safety testing in the target age group, especially in young children. Safety of one influenza vaccine in children should not be extrapolated to assumed safety of all influenza vaccines in children. The low rates of adverse events from influenza vaccines should not be a deterrent to the use of influenza vaccines because of the overwhelming evidence of the burden of disease due to influenza in children.

Abstract
BACKGROUND In 2009, Thailand recommended pregnant women be prioritized for influenza vaccination. Vaccine uptake among Thai pregnant women is lower than other high-risk groups. METHODS During December 2012-April 2013, we conducted a cross-sectional survey of a convenience sample of Thai pregnant women aged ≥ 15 years attending antenatal clinics at public hospitals in 8 of 77 provinces. A self-administered questionnaire covered knowledge, attitudes, and beliefs related to influenza vaccination using the Health Belief Model. We examined factors associated with willingness to be vaccinated using log-binomial regression models. RESULTS The survey was completed by 1031 (96%) of 1072 pregnant women approached. A total of 627 (61%) women had heard about influenza vaccine and were included in the analysis, of whom 262 (42%) were willing to be vaccinated, 155 (25%) had received a healthcare provider recommendation for influenza vaccination and 25 (4%) had received the influenza vaccine during the current pregnancy. In unadjusted models, high levels of perceptions of susceptibility (prevalence ratio [PR] 1.5, 95% CI 1.2-2.0), high levels of belief in the benefits of vaccination (PR 2.3, 95% CI 1.7-3.1), moderate (PR 1.7, 95% CI 1.2-2.3) and high (PR 3.4, 95% CI 2.6-4.5) levels of encouragement by others to be vaccinated (i.e., cues to action) were positively associated with willingness to be vaccinated. Moderate (PR 0.5, 95% CI 0.4-0.7) and high levels of (PR 0.5, 95% CI 0.4-0.8) perceived barriers were negatively associated with willingness to be vaccinated. In the final adjusted model, only moderate (PR 1.5, 95% CI 1.1-2.0) and high levels of cues to action (PR 2.7, 95% CI 2.0-3.6) were statistically associated with willingness to be vaccinated. CONCLUSION Cues to action were associated with willingness to be vaccinated and can be used to inform communication strategies during the vaccine campaign to increase influenza vaccination among Thai pregnant women.

Abstract
BACKGROUND In 2012, one third of cases in a multistate outbreak of variant influenza A(H3N2) virus ([H3N2]v) infection occurred in Ohio. We conducted an investigation of (H3N2)v cases associated with agricultural Fair A in Ohio. METHODS We surveyed Fair A swine exhibitors and their household members. Confirmed cases had influenza-like illness (ILI) and a positive laboratory test for (H3N2)v, and probable cases had ILI. We calculated attack rates. We determined risk factors for infection, using multivariable log-binomial regression. RESULTS We identified 20 confirmed and 94 probable cases associated with Fair A. Among 114 cases, the median age was 10 years, there were no hospitalizations or deaths, and 82% had swine exposure. In the exhibitor household cohort of 359 persons (83 households), we identified 6 confirmed cases (2%) and 40 probable cases (11%). An age of <10 years was a significant risk factor (P < .01) for illness. One instance of likely human-to-human transmission was identified. CONCLUSIONS In this (H3N2)v outbreak, no evidence of sustained human-to-human (H3N2)v transmission was found. Our risk factor analysis contributed to the development of the recommendation that people at increased risk of influenza-associated complications, including children aged <5 years, avoid swine barns at fairs during the 2012 fair season.

Abstract
Background. Variant influenza virus infections are rare but may have pandemic potential if person-to-person transmission is efficient. We describe the epidemiology of a multistate outbreak of an influenza A(H3N2) variant virus (H3N2v) first identified in 2011. Methods. We identified laboratory-confirmed cases of H3N2v and used a standard case report form to characterize illness and exposures. We considered illness to result from person-to-person H3N2v transmission if swine contact was not identified within 4 days prior to illness onset. Results. From 9 July to 7 September 2012, we identified 306 cases of H3N2v in 10 states. The median age of all patients was 7 years. Commonly reported signs and symptoms included fever (98%), cough (85%), and fatigue (83%). Sixteen patients (5.2%) were hospitalized, and 1 fatal case was identified. The majority of those infected reported agricultural fair attendance (93%) and/or contact with swine (95%) prior to illness. We identified 15 cases of possible person-to-person transmission of H3N2v. Viruses recovered from patients were 93%–100% identical and similar to viruses recovered from previous cases of H3N2v. All H3N2v viruses examined were susceptible to oseltamivir and zanamivir and resistant to adamantane antiviral medications. Conclusions. In a large outbreak of variant influenza, the majority of infected persons reported exposures, suggesting that swine contact at an agricultural fair was a risk for H3N2v infection. We identified limited person-to-person H3N2v virus transmission, but found no evidence of efficient or sustained person-to-person transmission. Fair managers and attendees should be aware of the risk of swine-to-human transmission of influenza viruses in these settings.

Abstract
Avoiding or limiting contact with swine at agricultural events may help prevent A(H3N2)v virus infections in such settings. During August 2011, influenza A (H3N2) variant [A(H3N2)v] virus infection developed in a child who attended an agricultural fair in Pennsylvania, USA; the virus resulted from reassortment of a swine influenza virus with influenza A(H1N1)pdm09. We interviewed fair attendees and conducted a retrospective cohort study among members of an agricultural club who attended the fair. Probable and confirmed cases of A(H3N2)v virus infection were defined by serology and genomic sequencing results, respectively. We identified 82 suspected, 4 probable, and 3 confirmed case-patients who attended the fair. Among 127 cohort study members, the risk for suspected case status increased as swine exposure increased from none (4%; referent) to visiting swine exhibits (8%; relative risk 2.1; 95% CI 0.2–53.4) to touching swine (16%; relative risk 4.4; 95% CI 0.8–116.3). Fairs may be venues for zoonotic transmission of viruses with epidemic potential; thus, health officials should investigate respiratory illness outbreaks associated with agricultural events.

Abstract
Background QuantiFERON-TB Gold In-Tube (QFT-GIT) is considered an alternative to the tuberculin skin test (TST) for the diagnosis of tuberculosis (TB) infection, but the programmatic impact of QFT-GIT implementation is largely unknown. In March, 2010, the Baltimore City Health Department (BCHD) introduced routine QFT-GIT testing for individuals referred to the TB program for suspected latent TB infection (LTBI). Design Retrospective study comparing LTBI diagnosis and treatment during the 13 months before and after QFT-GIT implementation at the BCHD TB clinic. Results 607 and 750 individuals were referred by community-providers for suspected LTBI in the pre- and post-QFT-GIT periods, respectively. Most individuals in the pre- and post-QFT-GIT periods were referred on the basis of a positive TST (597/607 [98%] vs. 690/750 [92%], respectively) and were foreign-born (363/607[59%] vs. 507/750[68%], respectively). BCHD performed QFT-GIT testing for 375/543 (69%) eligible individuals in the post-QFT-GIT period, of which 185 (49%) were positive, 178 (47%) were negative, 1 (0.25%) was indeterminate, and 11 (3%) did not yield results. Concordance of QFT-GIT with TST was low (183/352[52%]). Foreign-born individuals had higher proportions of QFT-GIT positivity (57%) than US-born individuals (36%; AOR 3.3 [95%CI 1.7–6.2]). Significantly fewer individuals received a final diagnosis of LTBI in the post-QFT-GIT period (397/567 [70%]) compared to the pre-QFT-GIT period (445/452 [98%], p<0.001). In the post-QFT-GIT period, only 230/399 (58%) of those receiving QFT-GIT testing had a final diagnosis of LTBI, while 167/168 (99%) of those without QFT-GIT testing were diagnosed with LTBI (p<0.001). There was no difference in treatment initiation between those with and without QFT-GIT testing (175/230 [76%]) vs. 133/167 [80%], respectively) in the post-QFT-GIT period. Conclusion QFT-GIT implementation for LTBI evaluation in a public health clinic significantly reduced the proportion of referred individuals in whom LTBI was diagnosed. QFT-GIT testing had no impact on treatment initiation or completion among those diagnosed with LTBI.

Abstract
Cryptococcal meningitis (CM) is a major cause of death among HIV-infected persons in sub-Saharan Africa. We conducted a study to describe the long-term outcomes during the pre-antiretroviral post-ART therapy period. Enrolled cases were those detected through population-based surveillance in Gauteng Province, South Africa, and diagnosed during March-November 2002 and July-September 2003 from eight large hospitals representing academic, provincial and rural settings. Of 1089 case-patients diagnosed with CM, 721 (70%) survived to discharge. Among the 256 with follow-up information, 154 (60%) were established to have died, 44% of whom died as outpatients. Overall, the 14- and 90-day survival post-diagnosis was 68% and 41%, respectively. On Cox proportional hazards multivariable analysis, severe disease was associated with shorter survival time; having received any antifungal treatment for the cryptococcal episode was associated with increased survival time at follow-up. Although most patients in this cohort survived the initial hospitalization, only 41% were still alive three months after diagnosis, with nearly half of deaths occurring outside a hospital. These data are an important baseline from which to measure effectiveness of public health management of CM in South Africa.

Abstract
BACKGROUND Microbial keratitis is a potentially sight threatening disease. Most cases respond well to antimicrobial therapy. However, in cases that progress despite intensive medical therapy, an urgent therapeutic penetrating keratoplasty (TPKP) is required. AIM To evaluate the indications and results of TPKP in Israel. METHODS A retrospective study reviewed the TPKP performed at the Goldschleger Eye Institute, Sheba Medical Center, between 1990-2003. The study included 18 cases of at least one-year follow-up. RESULTS The indications for TPKP included severe infectious keratitis unresponsive to medical treatment in 33% of the patients and severe corneal destruction in 66% of them. The infectious keratitis was diagnosed as bacterial keratitis in 44% of the patients, unidentified pathogen in 39%, mycotic in 11% and acanthamoeba in 6% of the patients. Risk factors in the patients with microbial keratitis requiring TPKP included: previous ocular disease in 39%, previous ocular surgery in 66%, systemic disorders in 28% and ocular risk factors in 28% patients. TPKP was successful in bacterial and acanthamoeba keratitis as far as the transparency of the graft and elimination of the infection and improvement of visual acuity. However, TPKP failed in mycotic and unidentified keratitis. The risk factors for failure included: previous ocular disease or surgeries, systemic disorders or large corneal grafts. CONCLUSIONS Therapeutic penetrating keratoplasty is an important and effective therapeutic tool for intractable bacterial and acanthamoeba keratitis. Prognostic factors for graft success include lack of ocular disease or previous surgeries, lack of systemic disorders or small corneal graft size.

Abstract
PURPOSE To compare the efficacy of two storage media, Optisol GS and Dexsol, in preservation of donor corneal epithelium. METHODS A total of 12 pairs of corneas not suitable for transplantation, all with intact epithelium, were used in this study, with one cornea of the pair stored in Optisol GS and its other counterpart in Dexsol. At each of three durations of storage--1, 2, and 4 days--four of these paired corneas were prepared for light microscopy and scanning and transmission electron microscopy. Another four pairs of control cornea were prepared in the same way and placed in universal fixative. MAIN OUTCOME MEASURES Evaluation of the corneas was made by two observers masked as to the identity of the storage medium and length of storage. Loss of epithelial cells was evaluated by light microscopy. The attachment of the epithelium to the basement membrane,cellular integrity, intercellular junctions, and intracellular organelles were evaluated and compared by electron microscopy. RESULTS The magnitude of epithelial loss correlated with the length of storage time. Control corneas maintained normal epithelium with preservation of all epithelial cell layers. Corneas stored for 1 day had minimal damage of the epithelium. Corneas stored for 2 days had a slight increase in epithelial damage, and corneas stored for up to 4 days showed a marked increase in epithelial damage. There were no significant differences between the two storage media. The basal cell layer was maintained in both the media at all time points, usually in good condition with mild-to-moderate damage in some cases. CONCLUSIONS Loss of donor epithelium is related mainly to the length of storage and is similar in both Optisol GS and Dexsol. The storage time should be less than 4 days,especially when performing penetrating keratoplasty on patients with ocular surface disorders.

Abstract
Differences in the pathobiologic features of alpha and beta thalassemic red cells include differing derangements in the ability of these cells to regulate their volume. To explore differences in cell hydration in these two red cell phenotypes, heterogeneity in hemoglobin concentration of individual red cells was quantitated. Red cells from 91 patients with alpha thalassemia (hemoglobin H disease) and 69 patients with beta thalassemia of the genotype beta-thal zero/Hb E were analyzed. Marked differences between these thalassemias were noted in the heterogeneity of hemoglobin concentration among individual cells. Decreased cell hemoglobin concentration and increased cell hydration were features of alpha-thalassemic blood samples, whereas both decreased and increased cell hemoglobin concentration as a result of cell hydration and dehydration, respectively, were features of beta-thalassemic blood samples. The documented differences in the hemoglobin concentration distributions should prove useful in distinguishing between the two thalassemic phenotypes.

Abstract
The efficacy of oral doxycycline, 100 mg/d for 14 days, in reducing the incidence of shigellosis in newcomers to an area hyperendemic for the disease was examined in a double-blind, placebo-controlled trial. Of 107 entrants, 100 completed the study; 50 received the drug and 50 received a placebo. Diarrheal disease and associated symptoms were monitored for 8 weeks. Starting on the 3rd day of the trial, an outbreak was observed, and Shigella flexneri type 2a was isolated from 6 subjects. Eight of the subjects in the treatment group had diarrhea (16%) compared with 37 in the placebo group (74%), providing a 79% protection rate. There was no significant difference in the occurrence of accompanying symptoms between the subjects suffering from diarrhea in both groups, but the duration of disease was shorter in the treatment group. Serologic study of the outbreak showed no significant difference in antibody response to S flexneri between the treatment (14 of 43) and placebo (18 of 39) groups. Doxycycline prophylaxis apparently is effective and probably does not prevent subclinical infection.
