Enhancing routine HIV and STI testing among young men who have sex with men: primary outcomes of the get connected clinical randomized trial (ATN 139).

BACKGROUND: Regular HIV and STI testing remain a cornerstone of comprehensive sexual health care. In this study, we examine the efficacy of Get Connected, a WebApp that combines test locators with personalized educational resources, in motivating young men who have sex with men (YMSM) to undergo regular HIV and STI testing. METHODS: Participants were randomly placed in one of two conditions. The first condition included the full version of GC (GC-PLUS), which included content tailored to users' psychosocial characteristics (e.g., age, race/ethnicity, relationship status, HIV/STI testing history). The second condition served as our attention-control and only included the testing locator (GC-TLO) for HIV/STI testing services. Participants were recruited from three cities (Houston, Philadelphia, and Atlanta) characterized by high HIV incidence. Assessments were collected at 1, 3-, 6-, 9- and 12-month follow-ups. RESULTS: Both versions of GC were acceptable and efficacious in increasing routine HIV and STI testing over a 12-month period. 40% of the sample reported testing at least twice, with no main effects observed across the two intervention arms (OR = 1.11; 95% CI: 0.69, 1.80), p =.66). Greater intervention effects were observed among YMSM who engaged more frequently with the intervention, with regional differences observed. CONCLUSIONS: Our findings underscore the need to cater to the diverse needs of YMSM through multilevel approaches. Broadly, mHealth HIV/STI testing interventions, such as Get Connected, would benefit from matching technologies to the local context to have the greatest impact. TRIAL REGISTRATION: This study is registered on ClinicalTrials.gov (NCT03132415).

Missed Prevention Opportunities: Why Young, Black MSM with Recent HIV Diagnosis did not Access HIV Pre-exposure Prophylaxis Services.

In the United States, HIV infection rate inequities persist, with new infections highest among young, Black men who have sex with men (YBMSM) in the South. We conducted 23 in-depth interviews with YBMSM newly diagnosed with HIV to explore awareness of and barriers to uptake of HIV pre-exposure prophylaxis (PrEP). Participants were recruited from two university-based HIV Clinics in Alabama and were: (1) 16-29 years of age, (2) diagnosed with HIV within the prior 365 days, (3) Black race, (4) self-identified as a cis-gender male reporting sex with men AND (5) did not report prior PrEP use. Interview guides were grounded in Anderson's Behavioral Healthcare Utilization Model (ABM), with embedded constructs from the situated Information, Motivation and Behavioral Skills theoretical framework. Coding was conducted by three independent coders using thematic analysis methods. Participants (N = 23) median age was 24, more than two-thirds reported annual incomes less than $15,000 and the majority (84%) identified as gay. Major themes that emerged as barriers to accessing PrEP included low prioritization and interests in using PrEP; low perceived HIV risk due to feelings of invincibility and trust in sex partners; lack of information about accessing PrEP; negative beliefs around PrEP; and the suggestion to change PrEP messaging from only targeting YBMSM. These findings indicate that there are important missed opportunities for HIV prevention with PrEP among YBMSM in the South. In these high-risk young men, tailored interventions are needed to better inform and frame perceptions around risk, knowledge, access and prioritization of PrEP.

En Estados Unidos, desigualdades en la tasa de infección por VIH persisten, y en el sur del pais, la tasa de nuevas infecciones hombres jóvenes Afro-americanos que tienen sexo con hombres son más altas. Realizamos veintitrés entrevistas en profundidad con YBMSM recién diagnosticado con VIH para explorar la conciencia y las barreras para la adopción de la profilaxis previa a la exposición al VIH (PrEP). Los participantes fueron reclutados de dos clínicas de VIH en centros medicos academicos en el estado de Alabama con los siguientes criterios: 1) 16-29 años de edad, 2) diagnostico VIH dentro de los 365 días, 3) raza afro-americana, 4) autoidentificados como un género cis-hombres que tienen sexo con hombres, y 5) no informaron el uso previo de PrEP. Las guías de la entrevista se basaron en el Modelo conductual de utilización de la salud (ABM) de Anderson, con construcciones integradas del marco teórico de Información, motivación y habilidades conductuales. Tres codificadores independientes codificaron utilizando métodos de análisis temáticos. La edad mediana de los participantes (N = 23) era de 24 años, más de dos tercios informaron ingresos anuales de menos de $15,000 (USD) y la mayoría (84%) se identificó como gay. Los temas principales que surgieron como barreras para acceder a PrEP incluyeron una baja priorización e interes en su; bajo riesgo percibido de VIH debido a sentimientos de invencibilidad y confianza en las parejas sexuales; falta de información sobre el acceso a PrEP; creencias negativas sobre PrEP; y la sugerencia de enfocar los mensajes sobre PreP no solo ha jovenes afro-americanos que tienen sexo con hombres. Estos hallazgos indican que hay importantes oportunidades perdidas para la prevención del VIH con PrEP entre esto jovenes en el Sur de EEUU. En estos hombres jóvenes de alto riesgo, se necesitan intervenciones personalizadas para mejor informar y enmarcar las percepciones sobre el riesgo, el conocimiento, el acceso y la priorización de PrEP.

Concordance in the reporting of intimate partner violence among male-male couples.

Intimate partner violence (IPV) among male couples is increasingly recognized as a public health concern. Research on IPV in opposite sex couples indicates frequent underreporting of IPV and high levels of discordance in reporting among dyads. Concordance studies inform refinement methods to measure the experience of IPV among dyads; however the lack of dyadic studies of male couples impedes our understanding of the extent to which IPV is differentially reported in male-male dyads. This study utilized baseline data from a randomized controlled trial of a behavioral intervention to optimize antiretroviral therapy (ART) adherence among 160 sero-discordant male couples in three US cities and provides the first analysis of concordance in reporting IPV among male couples. Low degrees of concordance in the reporting of IPV were identified among male dyads, with a greater proportion of men reporting violence perpetration than experiencing violence. The greater reporting of IPV perpetration may be linked to adherence to concepts of masculinity. The results underscore the unique experiences of IPV among male couples and the need to reexamine current IPV measurement and intervention strategies.

The rectal mucosa and condomless receptive anal intercourse in HIV-negative MSM: implications for HIV transmission and prevention.

Most HIV transmissions among men who have sex with men (MSM), the group that accounted for 67% of new US infections in 2014, occur via exposure to the rectal mucosa. However, it is unclear how the act of condomless receptive anal intercourse (CRAI) may alter the mucosal immune environment in HIV-negative MSM. Here, we performed a comprehensive characterization of the rectal mucosal immune environment for the phenotype and production of pro-inflammatory cytokines by CD4 and CD8 T cells, global transcriptomic analyses, and the composition of microbiota in HIV-negative MSM. Our results show that compared with men who had never engaged in anal intercourse, the rectal mucosa of MSM engaging in CRAI has a distinct phenotype characterized by higher levels of Th17 cells, greater CD8+ T cell proliferation and production of pro-inflammatory cytokines, molecular signatures associated with mucosal injury and repair likely mediated by innate immune cells, and a microbiota enriched for the Prevotellaceae family. These data provide a high-resolution model of the immunological, molecular, and microbiological perturbations induced by CRAI, will have direct utility in understanding rectal HIV transmission among MSM, and will enhance the design of future biomedical prevention interventions, including candidate HIV vaccines.

A syndemic including cigarette smoking and sexual risk behaviors among a sample of MSM in Shanghai, China.

OBJECTIVES: We explored possible correlates of cigarette smoking and their associations with levels of smoking among a sample of Chinese men who have sex with men (MSM). We also explored the syndemic associations of substance use and psychosocial problems on sexual risk behaviors. METHODS: Cross-sectional data collection from 404 MSM in Shanghai, China. RESULTS: MSM exhibit a high prevalence of smoking (66.3%). Both light and heavy smoking were associated with alcohol and drug use, depression, intimate partner violence, sexual attitudes, and gay identity (though the associations for light smokers were moderate compared to those for heavy smokers). CONCLUSIONS: Our findings indicate the presence of a health syndemic among MSM, and suggest that smoking prevention and cessation and other substance abuse interventions should be integrated into efforts preventing sexual risk behaviors among MSM.

A critical analysis of undergraduate students' cultural immersion experiences.

PURPOSE: This paper is concerned with the impact of an international health promotion experience on the understanding of culture among university students. Such immersion experiences are often cited as a strategy to prepare nurses for culturally appropriate practice. We describe students' epistemic movements over time with respect to cultural perspectives prior to, during and after a field study in Malawi. DESIGN: Data were collected at three time points from students in undergraduate nursing (n = 14) and non-nursing (n = 8) programs at a Canadian university. Two essays narrating participants' understanding of culture were submitted by consenting class members. A subgroup of nine participants (four nursing students, five from other disciplines) completed a third narrative following a subsequent field study course in Malawi. METHOD: Using narrative analysis, themes and structures in the participants' writing were identified and located within a constructivist or essentialist paradigm of cultural understanding. FINDINGS: Overwhelmingly, students' narratives were initially portrayed and informed by an essentialist understanding of culture. Later narratives demonstrated varying degrees of epistemic movement towards more constructivist viewpoints. Narratives that initially exhibited constructivist characteristics tended to display strengthened convictions in that paradigm. CONCLUSION: We challenge the claim that an international immersion experience immediately transforms participants into cultural experts; our evidence suggests that students experienced existential growth, but their understanding of culture did not change as a result of their brief stay in a different cultural context. Cultural immersion is a phenomenon that requires more critical analysis and systematic investigation to determine how such experiences contribute to learning about culture among nursing students.

Improving graduate education to support a branching career pipeline: recommendations based on a survey of doctoral students in the basic biomedical sciences.

Today's doctoral programs continue to prepare students for a traditional academic career path despite the inadequate supply of research-focused faculty positions. We advocate for a broader doctoral curriculum that prepares trainees for a wide range of science-related career paths. In support of this argument, we describe data from our survey of doctoral students in the basic biomedical sciences at University of California, San Francisco (UCSF). Midway through graduate training, UCSF students are already considering a broad range of career options, with one-third intending to pursue a non-research career path. To better support this branching career pipeline, we recommend that national standards for training and mentoring include emphasis on career planning and professional skills development to ensure the success of PhD-level scientists as they contribute to a broadly defined global scientific enterprise.

Evaluation of oral fluid enzyme immunoassay for confirmation of a positive rapid human immunodeficiency virus test result.

The CDC recommends that a reactive rapid human immunodeficiency virus (HIV) test be confirmed with an approved supplemental test; the performance of an intermediate enzyme immunoassay (EIA) is optional. In support of this recommendation, it was found that of 1,431 reactive rapid HIV test results, 2 (0.1%) had false-negative oral fluid Western blot results and both had false-negative EIA results.

Effects of repeated oral examinations on ophthalmology residents.

BACKGROUND/AIM: Oral examinations are required for board certification in Ophthalmology in the USA. The current literature offers no recommendation on the number of administrations during residency. The purpose of this study was to determine how often oral examinations (OEs) should be administered and what effects repeated OEs might have on residents' comfort level with OEs and confidence level in their knowledge base. METHODS: From 2004 to 2006, a structured oral examination was administered every 4 months to ophthalmology residents at the University of Arkansas for Medical Sciences. A survey was administered just prior to each oral examination. RESULTS: After two oral examinations, self-confidence and ability to self-assess one's knowledge increased and anxiety decreased in the residents. Residents' belief that they could pass an oral examination for board certification statistically improved after the third oral examination. CONCLUSIONS: To achieve the full benefits of oral examination training, the exam should be taken at least three times during residency. Formal, structured oral examinations, repeated over time, seem to reduce resident anxiety and improve the residents' ability to realistically assess their level of preparation for an OE.

Low prevalence of antiretroviral resistance among persons recently infected with human immunodeficiency virus in two US cities.

Resistance testing for treatment-naïve, recently HIV-infected persons is not currently recommended; its clinical value will depend on the prevalence of resistance-associated mutations among recently infected persons. To estimate this prevalence, specimens were collected during 1997-1999 in Seattle and Los Angeles from drug-naïve, recently HIV-infected persons. HIV-1 protease and reverse transcriptase (RT) RNA sequences were amplified from plasma by RT-polymerase chain reaction (RT-PCR), sequenced, and analysed. Of 69 patients, five (7%) had resistance-associated mutations: three (4%) had primary mutations associated with resistance to nucleoside reverse transcriptase inhibitors (NRTI) or non-nucleoside-RTIs, and three patients (4%) had secondary NRTI mutations. No primary mutation associated with resistance to protease inhibitors was observed. Mean age of the five persons with resistance-associated mutations (38 years) was higher than that of the 64 persons without resistance-associated mutations (31 years, P=0.04). The findings suggest that the prevalence of resistance-associated mutations among persons recently infected with HIV in these cities is low.

Measuring critical thinking in problem-based learning discourse.

BACKGROUND: Critical thinking (CT) is a composite of skills linked to problem-based learning (PBL). PURPOSES: This study has 3 purposes: (a) to determine if PBL discourse could be coded for CT, (b) to demonstrate reliable coding, and (c) to determine whether a CT ratio would provide a valid measure to compare 2 PBL groups. METHODS: Using prior research, we refined the code for a content analysis of PBL transcripts. Raters coded 6 hr of transcripts and computed CT ratios for each of the 5 CT stages. Average interrater agreement was 85.5%. CT ratios appeared to differ between 2 PBL groups delivered in 2 modalities. RESULTS: PBL discourse could be coded following a CT framework. Independent raters reliably applied the code, and the resulting CT ratios detected tenable differences. CONCLUSIONS: This approach could provide useful information about the effect of case modality.

Evaluation of United States-licensed human immunodeficiency virus immunoassays for detection of group M viral variants.

Six Food and Drug Administration (FDA)-licensed human immunodeficiency virus type 1 (HIV-1) and HIV-1/2 immunoassays, including five enzyme immunoassays and one rapid test, were challenged with up to 250 serum samples collected from various global sites. The serum samples were from individuals known to be infected with variants of HIV-1 including group M subtypes A, B, B', C, D, E, F, and G and group O. All immunoassays detected the vast majority of samples tested. Three samples produced low signal over cutoff values in one or more tests: a clade B sample, an untypeable sample with a low antibody titer, and a group O sample. It is concluded that HIV-1 immunoassays used in the United States are capable of detecting most HIV-1 group M variants.

Effect of influenza vaccination on disease progression among HIV-infected persons.

OBJECTIVE: To describe the effect of influenza vaccination on long-term change in CD4 count and HIV RNA level, and on progression to AIDS or death. DESIGN AND SETTING: A longitudinal medical record review set in 113 medical clinics in 10 United States cities. PATIENTS: A total of 36,050 HIV-infected persons aged > or = 13 years in care for HIV infection. MAIN OUTCOME MEASURES: Change in CD4 count and HIV RNA level at follow-up (3-12 months after vaccination); hazard ratios (HR) for association of influenza vaccine with progression from baseline CD4 or HIV RNA level to AIDS and to death. RESULTS: The median CD4 count among all persons decreased 28 cells/year during follow-up, with no difference in change in CD4 count between the 8007 (40%) vaccinated (median = 6 months, vaccine to follow-up CD4 count) and the 11,794 unvaccinated persons. In a viral load subanalysis, median HIV RNA level decreased 90 copies/ml per year among all persons during follow-up; decreases were not different between vaccinated and unvaccinated persons (median = 7 months, vaccine to follow-up HIV RNA level determination). Influenza vaccination was weakly associated with decreased risk of progression to clinical AIDS [HR 0.93; 95% confidence interval (CI), 0.87-0.99], but not associated with time to death (HR, 0.97; CI, 0.93-1.01). CONCLUSIONS: No negative long-term effect of influenza vaccination on CD4 counts, HIV RNA levels, or progression to AIDS or death was found in this HIV-infected population. These data suggest that physicians should not withhold influenza vaccine because of concerns about long-term detrimental effects of increased viral replication.

Aspergillosis among people infected with human immunodeficiency virus: incidence and survival. Adult and Adolescent Spectrum of HIV Disease Project.

Aspergillosis is a life-threatening fungal infection in immunocompromised people, including people infected with human immunodeficiency virus (HIV). We determined the incidence of aspergillosis among HIV-infected people and survival after aspergillosis diagnosis by use of a national HIV surveillance database. Among 35,252 HIV-infected patients, the incidence of aspergillosis was 3.5 cases per 1000 person-years (p-y; 95% confidence interval [CI], 3.0-4.0 per 1000 p-y). Incidence was higher among people aged > or =35 years (4.1 per 1000 p-y, 95% CI, 3. 5-4.8), among people with CD4 counts of 50-99 cells/mm(3) (5.1 per 1000 p-y, 95% CI, 2.8-7.3), or CD4 counts of <50 cells/mm(3) (10.2 per 1000 p-y, 95% CI, 8.0-12.2), versus people with CD4 counts of >200 cells/mm(3), people with > or =1 acquired immune deficiency syndrome-defining opportunistic illness (8.6 per 1000 p-y, 95% CI, 7.4-9.9), and people who were prescribed at least one medication associated with neutropenia (27.7 per 1000 p-y, 95% CI, 21.0-34.3). Median survival time after diagnosis of aspergillosis was 3 months, and 26% survived for > or =1 year. These findings suggest that aspergillosis is uncommon, occurs especially among severely immunosuppressed or leukopenic HIV-infected people, and is associated with poor survival.

Genetic factors associated with thrombosis in pregnancy in a United States population.

OBJECTIVE: Polymorphisms in the genes for factor V (factor V Leiden), prothrombin, methylenetetrahydrofolate reductase, and angiotensin-converting enzyme have been associated with the occurrence of venous thrombosis. The objective of this study was to determine the relationships of these polymorphisms to thrombosis during pregnancy. STUDY DESIGN: This case-control study included 41 case patients with venous thrombosis during pregnancy and 76 control subjects matched for hospital and for race (white vs black) who had a normal pregnancy. RESULTS: Among white subjects, mutations in the genes for factor V and prothrombin were associated with increased risks of venous thrombosis during pregnancy (factor V: odds ratio, 18.3; 95% confidence interval, 2.7-432; P =.001; prothrombin: odds ratio infinity; 95% lower confidence limit, 1.7; P =.01). No black subject had either of these two mutations. For both black and white subjects the D/D genotype of the gene for angiotensin-converting enzyme entailed increased risk compared with the other genotypes (odds ratio, 2.7; 95% confidence interval, 1.2-6.3; P =.02). The polymorphism in the gene for methylenetetrahydrofolate reductase was unrelated to thrombosis during pregnancy among both blacks and whites. CONCLUSION: Women who had thrombotic complications during pregnancy demonstrated an increased prevalence of genetic mutations related to coagulation. The additional risk of thrombosis during pregnancy associated with such genetic mutations can be substantial.

Balance, mobility, and falls among elderly African American women.

OBJECTIVE: To compare balance, mobility, recent falls, and injuries among elderly African American and white women. DESIGN: This was a nonexperimental study. Participants, who were older than 65 yr of age, able to walk at least 30 ft, not residing in a nursing home, and with no acute medical problems, were recruited from 17 senior citizens' community centers. RESULTS: Compared with white women (n=180), African American women (n = 118) took fewer medications, had greater body mass indexes, had less muscle strength, and had more medical conditions and neurologic abnormalities. Additionally, these women were less active and had poorer performances on an obstacle course. The two groups had a similar histories of falls and injuries. For both groups, activity level and neurologic findings were predictors of obstacle course performance. For white women, muscle strength was an additional predictor of obstacle course performance. An additional predictor for African American women was range of motion. CONCLUSION: The poorer balance and mobility of African American women compared with white women may have consequences such as their functional dependence, resulting in their greater use of hospitals and formal and informal health services.

Epidemiology of thrombosis in HIV-infected individuals. The Adult/Adolescent Spectrum of HIV Disease Project.

OBJECTIVE: To describe the incidence of clinically recognized thrombosis and associated factors among individuals infected with HIV. DESIGN: A longitudinal medical record review. SETTING: Over 100 medical clinics in nine US cities. PATIENTS: A total of 42 935 individuals aged 13 years or older with HIV infection, observed for an average of 2.4 years. MAIN OUTCOME MEASURES: The incidence of thrombosis among HIV-infected individuals; adjusted odds ratios for factors associated with thrombosis. RESULTS: The incidence of thrombosis among HIV-infected individuals was 2.6/1000 person-years (PY). Factors significantly associated with thrombosis included: age of 45 or more years (adjusted odds ratio [AOR], 1.9; 95% confidence interval [CI], 1.4-2.7); a diagnosis of cytomegalovirus disease or retinitis (AOR, 1.9; CI, 1.2-2.9), or other AIDS-defining opportunistic illness (AOR, 1.5; CI, 1.1-2.2); hospitalization (AOR, 3.3; CI, 2.5-4.4); and the prescription of megestrol acetate (AOR, 2.0; CI 1.3-2.9) or indinavir (AOR, 2.4; CI 1.4-4.3). The prescription of other protease inhibitors, sex, race, and mode of HIV exposure were not associated with thrombosis. CONCLUSION: Among HIV-infected individuals, clinically detected thrombosis is more common in those who have opportunistic illnesses, for whom megestrol acetate or indinavir have been prescribed, who have been hospitalized, and who are aged 45 years or older. Physicians should be aware of the risks of thrombosis in order to promote the early identification and appropriate treatment or prophylaxis. Further study is needed to characterize the association between indinavir and thrombosis.

Nursing documentation versus standardized assessment of cognitive status in hospitalized medical patients.

Although the literature discusses the importance of assessing cognitive status, little research has explored the concordance of nurses' documentation of cognitive status and standardized assessment. This study examined nurses documentation of cognitive status in 42 medically hospitalized individuals (mean age 51.9, SD = 10.1 years) using a variety of standardized measures. Although the chart review revealed no documentation of impaired cognitive status, impaired performance in 24 to 67% of the cognitive measures was identified. This study suggests nurses are missing cognitive impairment in hospitalized patients by limiting assessment to orientation. Use of a combination of several brief screening measures, such as the Clock Drawing Test and the standardized Mini-Mental State Examination, would provide timely, effective, and inexpensive assessment of cognitive status.

Human immunodeficiency virus (HIV) subtype surveillance of African-born persons at risk for group O and group N HIV infections in the United States.

A population-based surveillance registry was used to identify human immunodeficiency virus (HIV)-infected persons in the United States at increased risk for group O and group N infections (those born in or near African countries where group O infection has been reported). Of 155 eligible subjects, 37 gave samples. By phylogenetic and serologic analysis, 32 were infected with group M (16 with subtype A, 5 with B, 7 with C, and 1 each with subtypes D, F2, G, and recombinant A/J) and 2 with group O but none with group N virus. For 3, samples could not be typed by serology or amplified by polymerase chain reaction using group M-, O-, or N-specific primers. In the United States, group O HIV infection is uncommon; no case of group N infection was found. African-born persons may have HIV strains typical of their birth country. Ongoing subtype surveillance may allow early identification of novel or emerging HIV strains.

Modifying a functional obstacle course to test balance and mobility in the community.

A previously reported functional obstacle course (FOC) developed to assess elderly persons with and without balance and mobility impairment was used in a hospital-based study of 237 participants. A new modified version of the FOC was developed for use in a community-based study, by placing some obstacles next to walls instead of between parallel bars. These modifications eliminate the need for parallel bars or for extra personnel to interchange the obstacles. We were concerned that the modifications could affect performance scores, because touching or holding onto the now eliminated parallel bars could influence FOC scores under the original scoring system. To determine the effect of these modifications on FOC performance, we tested 36 volunteers, (18 fallers [falls within last year] and 18 non-fallers), on the modified parts of the old and new versions of the FOC. Random testing order and inter-trial rests were used. For both the old and new FOC versions, we summed quality and task completion time scores from the six modified obstacles (artificial turf, carpet, pine bark, sand, up ramp and down ramp) to create scores for quality and time. Our hypothesis was that there would be no performance difference between the original and modified obstacle course. Using a two-factor repeated-measures analysis of variance, we found no difference in quality scores between the two FOC versions and no effect of an interaction between faller status and the course versions. We did find that the time was approximately 2 seconds longer for the new version; however, the time increase was the same for fallers and non-fallers. These data show that fallers and non-fallers have comparable performance on both versions of the FOC; however, to compare the two obstacle courses we recommend an adjustment of 2 seconds in time scores. The obstacle course modifications will facilitate more extensive and efficient use of the obstacle course as a research tool to assess balance and mobility.
