Systematic review of social determinants of health associated with HIV testing among Hispanic/Latino gay, bisexual, and other men who have sex with men in the United States
Crepaz N , Salabarría-Peña Y , Mullins MM , Gunn JKL , Higa DH . AIDS Educ Prev 2023 35 (1) 36-s6 This systematic review synthesized published literature (January 2008-October 2021) about the association between social determinants of health (SDOH) and HIV testing among Hispanic/Latino gay, bisexual, and other men who have sex with men (HLMSM), a group disproportionally affected by HIV. Having higher education than a high school diploma, health insurance and access to health care services, and visiting a health care provider in the past 12 months were some of the determinants associated with HIV testing, while limited English proficiency was associated with reduced odds of HIV-testing among HLMSM. More research is needed to understand the relationship of SDOH (especially neighborhood) and HIV testing, how SDOH may affect HIV testing among different HLMSM groups, and how to increase self-testing and use of e-health in this priority population. Additionally, culturally and linguistically appropriate multilevel interventions and health services for HLMSM are urgently needed to diagnose HIV as early as possible after infection. |
Strategies to improve HIV care outcomes for people with HIV who are out of care: a meta-analysis
Higa DH , Crepaz N , Mullins MM , Adegbite-Johnson A , Gunn JKL , Denard C , Mizuno Y . AIDS 2022 36 (6) 853-862 OBJECTIVE: The aim of this study was to evaluate the effectiveness of five intervention strategies: patient navigation, appointment help/alerts, psychosocial support, transportation/appointment accompaniment, and data-to-care on HIV care outcomes among persons with HIV (PWH) who are out of care (OOC). DESIGN: A systematic review with meta-analysis. METHODS: We searched CDC's Prevention Research Synthesis (PRS) Project's cumulative HIV database to identify intervention studies conducted in the U.S., published between 2000 and 2020 that included comparisons between groups or prepost, and reported at least one relevant outcome (i.e., re-engagement and retention in HIV care, and viral suppression). Effect sizes were meta-analyzed using random-effect models to assess intervention effectiveness. RESULTS: Thirty-nine studies reporting on 42 unique interventions met the inclusion criteria. Overall, intervention strategies are effective in improving re-engagement in care [odds ratio (OR) = 1.79; 95% confidence interval (95% CI): 1.36-2.36, k = 14], retention in care (OR = 2.01; 95% CI: 1.64-2.64, k = 22), and viral suppression (OR = 2.50; 95% CI: 1.87-3.34, k = 27). Patient navigation, appointment help/alerts, psychosocial support, and transportation/appointment accompaniment improved all three HIV care outcomes. Data-to-care improved re-engagement and retention but had insufficient evidence for viral suppression. CONCLUSION: Several strategies are effective for improving HIV care outcomes among PWH who are OOC. More work is still needed for consistent definitions of OCC and HIV care outcomes, better reporting of intervention and cost data, and identifying how best to implement and scale-up effective strategies to engage and retain OOC PWH in care and reach the ending the HIV epidemic goals. |

J Clin Microbiol 2021 60 (1) Jcm0174221 Point-of-care antigen tests are an important tool for SARS-CoV-2 detection. Antigen tests are less sensitive than real-time reverse-transcriptase PCR (rRT-PCR). Data on the performance of the BinaxNOW antigen test compared to rRT-PCR and viral culture by symptom and known exposure status, timing during disease or exposure period and demographic variables are limited. During November 3(rd)-17(th), 2020, we collected paired upper respiratory swab specimens to test for SARS-CoV-2 by rRT-PCR and Abbott BinaxNOW (BinaxNOW) antigen test at two community testing sites in Pima County, Arizona. We administered a questionnaire to capture symptoms, known exposure status and previous SARS-CoV-2 test results. Specimens positive by either test were analyzed by viral culture. Previously we showed overall BinaxNOW sensitivity was 52.5%. Here we showed BinaxNOW sensitivity increased to 65.7% among currently symptomatic individuals reporting a known exposure. BinaxNOW sensitivity was lower among participants with a known exposure and previously symptomatic (32.4%) or never symptomatic (47.1%) within 14 days of testing. Sensitivity was 71.1% in participants within a week of symptom onset. In participants with a known exposure, sensitivity was highest 8-10 days post-exposure (75%). The positive predictive value for recovery of virus in cell culture was 56.7% for BinaxNOW-positive and 35.4% for rRT-PCR-positive specimens. Result reporting time was 2.5 hours for BinaxNOW and 26 hours for rRT-PCR. Point-of-care antigen tests have a shorter turn-around time compared to laboratory-based nucleic acid amplification tests, which allows for more rapid identification of infected individuals. Antigen test sensitivity limitations are important to consider when developing a testing program. |
A rapid review of disparities in HIV prevention and care outcomes among Hispanic/Latino men who have sex with men in the United States
Crepaz N , Mullins MM , Higa D , Gunn JKL , Salabarría-Peña Y . AIDS Educ Prev 2021 33 (4) 276-289 In the United States, Hispanic/Latino men who have sex with men (HLMSM) are disproportionally affected by HIV. We conducted a rapid review of national surveillance data to examine disparities in HIV prevention and care outcomes among HLMSM. Thirteen reports provided relevant data from 2011 to 2018. Compared to White MSM, a higher percentage of HIV-negative HLMSM reported not taking PrEP and engaging in condomless sex; a lower percentage of HIV-negative HLMSM at risk for HIV reported PrEP awareness and use; and a lower percentage of HIV-positive HLMSM were aware of their status, linked to HIV care, and virally suppressed. Viral suppression rates in HLMSM were better among Ryan White clients than the national rates, suggesting that access to comprehensive care/services reduces disparities. Findings also call for identifying individual, social, and structural factors contributing to condomless sex without PrEP use and HIV status unawareness and identifying best approaches for scaling up comprehensive care/services. |
Effectiveness of HIV Stigma Interventions for Men who have Sex with Men (MSM) With and Without HIV in the United States: A Systematic Review and Meta-Analyses
Gunn JKL , Rooks-Peck C , Wichser ME , Denard C , McCree DH , Jeffries WL4th , DeLuca JB , Ross LW , Herron A , Barham T , Flores SA , Higa DH . AIDS Behav 2021 26 51-89 Stigma may contribute to HIV disparities for men who have sex with men (MSM). This systematic review quantified the effects of HIV stigma interventions for MSM on stigma and sex risk. We conducted a systematic search to identify US-based studies published between 2000 and June 2019 focused on HIV and MSM, and either measured stigma pre-post or included a stigma intervention component. Twenty-nine articles, representing 26 unique studies met inclusion criteria. Random effect models showed no intervention effect for reducing stigma and a non-significant increase in HIV testing. Significant decreases in condomless sex with males, condomless sex with females, and substance-influenced sex were found. Few intervention studies measured stigma pre-post. Findings suggest that including a stigma reduction component in interventions can improve HIV testing and reduce sex risk for MSM. Developing interventions to address stigma may be important in decreasing HIV infection among MSM and ending the HIV epidemic. |

Am J Public Health 2021 111 (5) e1-e10 Objectives. To assess SARS-CoV-2 transmission within a correctional facility and recommend mitigation strategies.Methods. From April 29 to May 15, 2020, we established the point prevalence of COVID-19 among incarcerated persons and staff within a correctional facility in Arkansas. Participants provided respiratory specimens for SARS-CoV-2 testing and completed questionnaires on symptoms and factors associated with transmission.Results. Of 1647 incarcerated persons and 128 staff tested, 30.5% of incarcerated persons (range by housing unit = 0.0%-58.2%) and 2.3% of staff tested positive for SARS-CoV-2. Among those who tested positive and responded to symptom questions (431 incarcerated persons, 3 staff), 81.2% and 33.3% were asymptomatic, respectively. Most incarcerated persons (58.0%) reported wearing cloth face coverings 8 hours or less per day, and 63.3% reported close contact with someone other than their bunkmate.Conclusions. If testing remained limited to symptomatic individuals, fewer cases would have been detected or detection would have been delayed, allowing transmission to continue. Rapid implementation of mass testing and strict enforcement of infection prevention and control measures may be needed to mitigate spread of SARS-CoV-2 in this setting. (Am J Public Health.

Evaluation of Abbott BinaxNOW Rapid Antigen Test for SARS-CoV-2 Infection at Two Community-Based Testing Sites - Pima County, Arizona, November 3-17, 2020.
Prince-Guerra JL , Almendares O , Nolen LD , Gunn JKL , Dale AP , Buono SA , Deutsch-Feldman M , Suppiah S , Hao L , Zeng Y , Stevens VA , Knipe K , Pompey J , Atherstone C , Bui DP , Powell T , Tamin A , Harcourt JL , Shewmaker PL , Medrzycki M , Wong P , Jain S , Tejada-Strop A , Rogers S , Emery B , Wang H , Petway M , Bohannon C , Folster JM , MacNeil A , Salerno R , Kuhnert-Tallman W , Tate JE , Thornburg NJ , Kirking HL , Sheiban K , Kudrna J , Cullen T , Komatsu KK , Villanueva JM , Rose DA , Neatherlin JC , Anderson M , Rota PA , Honein MA , Bower WA . MMWR Morb Mortal Wkly Rep 2021 70 (3) 100-105 Rapid antigen tests, such as the Abbott BinaxNOW COVID-19 Ag Card (BinaxNOW), offer results more rapidly (approximately 15-30 minutes) and at a lower cost than do highly sensitive nucleic acid amplification tests (NAATs) (1). Rapid antigen tests have received Food and Drug Administration (FDA) Emergency Use Authorization (EUA) for use in symptomatic persons (2), but data are lacking on test performance in asymptomatic persons to inform expanded screening testing to rapidly identify and isolate infected persons (3). To evaluate the performance of the BinaxNOW rapid antigen test, it was used along with real-time reverse transcription-polymerase chain reaction (RT-PCR) testing to analyze 3,419 paired specimens collected from persons aged ≥10 years at two community testing sites in Pima County, Arizona, during November 3-17, 2020. Viral culture was performed on 274 of 303 residual real-time RT-PCR specimens with positive results by either test (29 were not available for culture). Compared with real-time RT-PCR testing, the BinaxNOW antigen test had a sensitivity of 64.2% for specimens from symptomatic persons and 35.8% for specimens from asymptomatic persons, with near 100% specificity in specimens from both groups. Virus was cultured from 96 of 274 (35.0%) specimens, including 85 (57.8%) of 147 with concordant antigen and real-time RT-PCR positive results, 11 (8.9%) of 124 with false-negative antigen test results, and none of three with false-positive antigen test results. Among specimens positive for viral culture, sensitivity was 92.6% for symptomatic and 78.6% for asymptomatic individuals. When the pretest probability for receiving positive test results for SARS-CoV-2 is elevated (e.g., in symptomatic persons or in persons with a known COVID-19 exposure), a negative antigen test result should be confirmed by NAAT (1). Despite a lower sensitivity to detect infection, rapid antigen tests can be an important tool for screening because of their quick turnaround time, lower costs and resource needs, high specificity, and high positive predictive value (PPV) in settings of high pretest probability. The faster turnaround time of the antigen test can help limit transmission by more rapidly identifying infectious persons for isolation, particularly when used as a component of serial testing strategies. |
Multidisciplinary Community-Based Investigation of a COVID-19 Outbreak Among Marshallese and Hispanic/Latino Communities - Benton and Washington Counties, Arkansas, March-June 2020.
Center KE , Da Silva J , Hernandez AL , Vang K , Martin DW , Mazurek J , Lilo EA , Zimmerman NK , Krow-Lucal E , Campbell EM , Cowins JV , Walker C , Dominguez KL , Gallo B , Gunn JKL , McCormick D , Cochran C , Smith MR , Dillaha JA , James AE . MMWR Morb Mortal Wkly Rep 2020 69 (48) 1807-1811 By June 2020, Marshallese and Hispanic or Latino (Hispanic) persons in Benton and Washington counties of Arkansas had received a disproportionately high number of diagnoses of coronavirus disease 2019 (COVID-19). Despite representing approximately 19% of these counties' populations (1), Marshallese and Hispanic persons accounted for 64% of COVID-19 cases and 57% of COVID-19-associated deaths. Analyses of surveillance data, focus group discussions, and key-informant interviews were conducted to identify challenges and propose strategies for interrupting transmission of SARS-CoV-2, the virus that causes COVID-19. Challenges included limited native-language health messaging, high household occupancy, high employment rate in the poultry processing industry, mistrust of the medical system, and changing COVID-19 guidance. Reducing the COVID-19 incidence among communities that suffer disproportionately from COVID-19 requires strengthening the coordination of public health, health care, and community stakeholders to provide culturally and linguistically tailored public health education, community-based prevention activities, case management, care navigation, and service linkage. |
Characteristics and Outcomes of Contacts of COVID-19 Patients Monitored Using an Automated Symptom Monitoring Tool - Maine, May-June 2020.
Krueger A , Gunn JKL , Watson J , Smith AE , Lincoln R , Huston SL , Dirlikov E , Robinson S . MMWR Morb Mortal Wkly Rep 2020 69 (31) 1026-1030 SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19), is spread from person to person (1-3). Quarantine of exposed persons (contacts) for 14 days following their exposure reduces transmission (4-7). Contact tracing provides an opportunity to identify contacts, inform them of quarantine recommendations, and monitor their symptoms to promptly identify secondary COVID-19 cases (7,8). On March 12, 2020, Maine Center for Disease Control and Prevention (Maine CDC) identified the first case of COVID-19 in the state. Because of resource constraints, including staffing, Maine CDC could not consistently monitor contacts, and automated technological solutions for monitoring contacts were explored. On May 14, 2020, Maine CDC began enrolling contacts of patients with reported COVID-19 into Sara Alert (MITRE Corporation, 2020),* an automated, web-based, symptom monitoring tool. After initial communication with Maine CDC staff members, enrolled contacts automatically received daily symptom questionnaires via their choice of e-mailed weblink, text message, texted weblink, or telephone call until completion of their quarantine. Epidemiologic investigations were conducted for enrollees who reported symptoms or received a positive SARS-CoV-2 test result. During May 14-June 26, Maine CDC enrolled 1,622 contacts of 614 COVID-19 patients; 190 (11.7%) eventually developed COVID-19, highlighting the importance of identifying, quarantining, and monitoring contacts of COVID-19 patients to limit spread. In Maine, symptom monitoring was not feasible without the use of an automated symptom monitoring tool. Using a tool that permitted enrollees to specify a method of symptom monitoring was well received, because the majority of persons monitored (96.4%) agreed to report using this system. |
Characteristics of persons who report using only nicotine-containing products among interviewed patients with e-cigarette, or vaping, product use-associated lung injury - Illinois, August-December 2019
Ghinai I , Navon L , Gunn JKL , Duca LM , Brister S , Love S , Brink R , Fajardo G , Johnson J , Saathoff-Huber L , King BA , Jones CM , Krishnasamy VP , Layden JE . MMWR Morb Mortal Wkly Rep 2020 69 (3) 84-89 In 2019, the United States experienced an outbreak of e-cigarette, or vaping, product use-associated lung injury (EVALI) (1). Most EVALI patients have reported using tetrahydrocannabinol (THC)-containing e-cigarette, or vaping, products obtained from informal sources (2,3), and vitamin E acetate in these products has been closely linked with EVALI (4,5). However, some EVALI patients report using only nicotine-containing products. This study compared demographic, product use, and clinical characteristics of EVALI patients in Illinois who reported using only nicotine-containing e-cigarette, or vaping, products with those of patients who reported using any THC-containing products. Among 121 interviewed Illinois EVALI patients, 17 (14%) reported using only nicotine-containing products, including nine (7%) patients who had no indication of any THC use, based on self-report or toxicology testing. Compared with patients who used any THC-containing products, these nine patients were significantly more likely to be older and female and were less likely to experience constitutional symptoms or to have leukocytosis on initial evaluation. Although vitamin E acetate has been strongly linked with EVALI, evidence is not sufficient to rule out the contribution of other chemicals of concern, including chemicals in either THC- or non-THC-containing products, in some reported EVALI cases. The contributing cause or causes of EVALI for patients reporting use of only nicotine-containing products warrants further investigation. |
