RESUMEN

BACKGROUND: Oral HIV preexposure prophylaxis (PrEP) is safe and effective but underutilized. Health care providers' beliefs about PrEP and attitudes toward people who could benefit may affect PrEP access. METHODS: This mixed-methods study (2016-2018) was conducted in 8 New York City public sexual health clinics that implemented a PrEP program. Data included 32 in-depth qualitative interviews with clinicians, quantitatively coded to reflect their PrEP beliefs; a provider questionnaire; and 6 months of medical record visit data for these providers. Among patients with a PrEP indication, we examined the odds of a patient being initiated on PrEP associated with providers' PrEP beliefs and demographic characteristics, and patient characteristics. RESULTS: Providers reported strong support for offering PrEP to eligible patients. The majority denied concerns about possible development of drug-resistant viral strains, giving PrEP to people who might not benefit, and PrEP toxicity. Nevertheless, about one-third agreed with each of these concerns, and 55% thought PrEP use might limit condom use. Of 2176 patients with a PrEP indication, 20% were initiated. Providers with more restrictive PrEP beliefs did not have lower odds of initiating patients on PrEP. Women as well as Black and Latinx patients were less likely to be initiated on PrEP. CONCLUSIONS: Contrary to our hypotheses, providers' negative PrEP beliefs did not seem to reduce initiation of PrEP for eligible patients. This may be attributable to clear clinical protocols, strong staff support, and training on implementing PrEP in this setting. Racial and gender disparities in PrEP uptake urgently require attention.

RESUMEN

Structural determinants of health drive inequities in the acquisition of human immunodeficiency virus (HIV) and the use of preexposure prophylaxis (PrEP) for HIV prevention among cisgender women in the United States. However, current PrEP clinical guidance and implementation paradigms largely focus on individual behaviors and characteristics, resulting in missed opportunities to improve PrEP access, and the implicit transferring of prevention work from health systems to individuals. In this viewpoint article, we outline ways to apply a structural lens to clinical guidance and PrEP implementation for women and propose areas for future work.

RESUMEN

Linkage to care following an HIV diagnosis remains an important HIV care continuum milestone, even in the era of universal ART eligibility. In an 8-month prospective cohort study among 459 (309 women, 150 men) newly-diagnosed HIV-positive individuals in three public-sector clinics in Durban metropolitan region, South Africa, from 2010 to 2013, median time to return to clinic for CD4+ results (linkage) was 10.71 weeks (95% CI 8.52-12.91), with 54.1% 3-month cumulative incidence of linkage. At study completion (9.23 months median follow-up), 26.2% had not linked. Holding more positive outcome-beliefs about enrolling in care was associated with more rapid linkage [adjusted hazard ratio (AHR)each additional belief 1.31; 95% CI 1.05-1.64] and lower odds of never linking [adjusted odds ratio (AOR) 0.50; 95% CI 0.33-0.75]. Holding positive ARV beliefs was strongly protective against never linking to care. Age over 30 years (AHR 1.59; 95% CI 1.29-1.97) and disclosing one's HIV-positive status within 30 days of diagnosis (AHR 1.52; 95% CI 1.10-2.10) were associated with higher linkage rates and lower odds of never linking. Gender was not associated with linkage and did not alter the effect of other predictors. Although expanded access to ART has reduced some linkage barriers, these findings demonstrate that people's beliefs and social relations also matter. In addition to structural interventions, consistent ART education and disclosure support, and targeting younger individuals for linkage are high priorities.

RESUMEN

Despite the promise of human immunodeficiency virus (HIV) pre-exposure prophylaxis (PrEP), PrEP remains underutilized, often due to clinician factors. Academic or public health detailing is a process by which university and/or government groups employ the marketing practices of pharmaceutical companies to improve clinical practice. We describe the novel application of detailing to increase PrEP prescribing and related care in New York City and New England. Detailing can play a crucial role in PrEP implementation.

RESUMEN

As of 2017, the Centers for Disease Control and Prevention (CDC) HIV testing guidelines recommend that those at increased risk for HIV are tested two to four times per year. Evidence-based interventions that promote frequent and repeated testing remain sparse. We conducted a systematic review to: (1) identify frequent testing interventions; and (2) determine which were successful in increasing frequent testing rates. We searched PubMed, PsycINFO, Web of Science, Embase, and CINAHL for peer-reviewed articles published between January 1, 2010 and September 30, 2017. Ten studies met inclusion criteria. Operationalization of frequent HIV testing varied widely across studies. Four interventions involved text message reminders for HIV testing, three involved community-based testing, two self-testing, and one rapid testing. Text message reminder interventions were most successful in increasing rates of frequent HIV testing. Future research should standardize frequent testing measurement to allow for more robust comparisons of intervention efficacy.

RESUMEN

The scale-up of preexposure prophylaxis (PrEP) represents a paradigm shift in HIV prevention that poses unique challenges for public health programs. Monitoring of PrEP implementation at the population level is a national priority, with particular significance in New York City (NYC) given the substantial HIV burden and the prominence of PrEP in state and local Ending the Epidemic program plans. We highlight the importance of local monitoring and evaluation of PrEP implementation outcomes and describe the experience at the NYC Health Department, which includes engaging communities, triangulating a variety of data sources regarding PrEP implementation, and leveraging those data to help guide programming. In NYC, we used data from national surveillance systems and incorporated PrEP-related indicators into existing local data collection systems to help illustrate gaps in PrEP awareness and use. Ultimately, ensuring that PrEP achieves the desired impact at the population level depends on identifying disparities through appropriate and accurate measurement, and addressing them through evidence-based programs.

RESUMEN

The Garífuna, an ethnic minority group in Honduras, have been disproportionately affected by HIV. Previous research suggests that migration and high rates of multiple sexual partnerships are major drivers of the epidemic. Using data from a 2012 population-based survey, we assessed whether temporary migration was associated with (1) multiple sexual partnerships and (2) sexual concurrency among Garífuna men and women in Honduras. Among both men and women, temporary migration in the last year was associated with an increased likelihood of multiple sexual partnerships and with concurrency, though only the association between migration and multiple sexual partnerships among men was statistically significant (Adjusted Prevalence Ratio 1.7, 95 % CI 1.2-2.4). Migration may contribute to HIV/STI vulnerability among Garífuna men and women via increases in these sexual risk behaviors. Research conducted among men and women at elevated risk of HIV should continue to incorporate measures of mobility, including history of internal migration.

RESUMEN

Brief non-commercial sexual encounters among patrons of social venues are increasing in China, but whether these encounters increase syphilis risk is unknown. We surveyed and tested 797 men and women at randomly selected social venues in urban Liuzhou and three surrounding counties. The percent reporting recent non-commercial one-time sex ranged from 14.5% of county women to 24.8% of urban men. 2.4% of men and 3.7% of women had a positive rapid syphilis test. Men reporting non-commercial one-time sex were significantly more likely to have a positive rapid syphilis test than other men (7.4 vs. 0.9%). Among women, commercial sex was more strongly associated with syphilis than non-commercial one-time sex (6.0 vs. 0.7%). Recent one-time sex was common and associated with syphilis among men. Venue-based HIV/STI prevention methods may be warranted among persons who do not engage in commercial sex, but frequently engage in one-time sex.

RESUMEN

The re-emerging syphilis epidemic in China is documented among sex workers, but little is known about STI risk among the broader group of women who work at entertainment and service venues, many of whom do not self-identify as sex workers. In 2009 in Liuzhou, China, community informants identified venues where people meet sexual partners. Characteristics of a stratified random sample of venues were collected during venue visits. Female staff at 42 venues were interviewed and tested for syphilis. The results showed that venue characteristics, worker behaviors, and syphilis prevalence differed by venue type. Service venue workers had more sexual partners, were more likely to report sex work, and more likely to have a positive syphilis test than entertainment venue workers (prevalence ratio: 5.4; 95% CI 1.4-20.6). To conclude, risk of syphilis differs by venue type and is higher at service venues, even among women who do not report commercial sex.

RESUMEN

OBJECTIVES: To compare two methods for sampling female sex workers (FSWs) for bio-behavioural surveillance. We compared the populations of sex workers recruited by the venue-based Priorities for Local AIDS Control Efforts (PLACE) method and a concurrently implemented network-based sampling method, respondent-driven sampling (RDS), in Liuzhou, China. METHODS: For the PLACE protocol, all female workers at a stratified random sample of venues identified as places where people meet new sexual partners were interviewed and tested for syphilis. Female workers who reported sex work in the past 4 weeks were categorised as FSWs. RDS used peer recruitment and chain referral to obtain a sample of FSWs. Data were collected between October 2009 and January 2010. We compared the socio-demographic characteristics and the percentage with a positive syphilis test of FSWs recruited by PLACE and RDS. RESULTS: The prevalence of a positive syphilis test was 24% among FSWs recruited by PLACE and 8.5% among those recruited by RDS and tested (prevalence ratio 3.3; 95% CI 1.5 to 7.2). Socio-demographic characteristics (age, residence and monthly income) also varied by sampling method. PLACE recruited fewer FSWs than RDS (161 vs 583), was more labour-intensive and had difficulty gaining access to some venues. RDS was more likely to recruit from areas near the RDS office and from large low prevalence entertainment venues. CONCLUSIONS: Surveillance protocols using different sampling methods can obtain different estimates of prevalence and population characteristics. Venue-based and network-based methods each have strengths and limitations reflecting differences in design and assumptions. We recommend that more research be conducted on measuring bias in bio-behavioural surveillance.

RESUMEN

Although HIV pre-exposure prophylaxis can decrease new cases of HIV by up to 99%, many patients who could benefit from pre-exposure prophylaxis never receive prescriptions for it. Because pre-exposure prophylaxis is indicated for patients who do not have an infectious disease, increasing pre-exposure prophylaxis prescribing by primary care and generalist clinicians represents a key element of the Ending the HIV Epidemic in the U.S. initiative. This review provides an overview of academic detailing and how it is currently being used to increase pre-exposure prophylaxis prescribing. Academic detailing is outreach education that engages with clinicians in 1-to-1 or small group interactions focused on identifying and addressing an individual clinician's needs to increase their use of evidence-based practices. Academic detailing has been proven in multiple previous research studies, and the principles required for successful implementation include interactivity, clinical relevance of content, and focus on defined behavior change objectives. Clinician barriers to pre-exposure prophylaxis prescribing may occur in the domains of knowledge, attitudes, or behavior, and academic detailing has the potential to address all of these areas. State and local health departments have developed academic detailing programs focused on pre-exposure prophylaxis prescribing and other elements of HIV prevention-sometimes describing the approach as public health detailing. Few studies of academic detailing for pre-exposure prophylaxis have been published to date; rigorous evaluation of HIV-specific adaptations and innovations of the approach would represent an important contribution. In the setting of the COVID-19 pandemic, interest in virtual delivery of academic detailing has grown, which could inform efforts to implement academic detailing in rural communities and other underserved areas. Increasing this capacity could make an important contribution to Ending the HIV Epidemic in the U.S. and other HIV prevention efforts.

RESUMEN

INTRODUCTION: Equitable access to HIV pre- and postexposure prophylaxis for women is essential to ending the HIV epidemic. Providers' lack of knowledge and comfort in discussing and prescribing pre-exposure prophylaxis to women persist as barriers. METHODS: From May to November 2019, the New York City Health Department conducted its first public health detailing campaigns among women's healthcare providers to promote pre- and postexposure prophylaxis and the associated best practices. Over 2 campaigns (10 weeks each), trained Health Department representatives visited providers for 1-on-1 visits at select practices to promote key messages. Representatives distributed an Action Kit that addressed knowledge gaps and practice needs on providing pre-exposure prophylaxis and postexposure prophylaxis to cisgender and transgender women. Providers completed an assessment at the beginning of initial and follow-up visits, used to compare responses across visits. Statistically significant changes were evaluated by generalized linear models of bivariate outcomes, adjusted for nonindependence of providers at the same practice. RESULTS: Representatives visited 1,348 providers specializing in primary care (47%), women's health (30%), adolescent health (7%), infectious disease (4%), and other (12%) at 860 sites; 1,097 providers received initial and follow-up visits. Provider report of ever prescribing pre-exposure prophylaxis increased by 12% (n=119 providers); increases were reported in measures of taking sexual history, asking about partners' HIV status, providing postexposure prophylaxis, recognizing pre-exposure prophylaxis's effectiveness, and discussing and referring for pre-exposure prophylaxis. CONCLUSIONS: After public health detailing, women's healthcare providers report increased adoption of recommended practices that promote pre- and postexposure prophylaxis uptake and sexual wellness among women. Detailing may be adaptable to other regions and contexts to reach providers.

RESUMEN

Despite expanded antiretroviral therapy (ART) eligibility in South Africa, many people diagnosed with HIV do not initiate ART promptly, yet understanding of the reasons is limited. Using data from an 8-month prospective cohort interview study of women and men newly-diagnosed with HIV in three public-sector primary care clinics in the eThekwini (Durban) region, South Africa, 2010-2014, we examined if theoretically-relevant social-structural, social-cognitive, psychosocial, and health status indicators were associated with time to ART initiation. Of 459 diagnosed, 350 returned to the clinic for their CD4+ test results (linkage); 153 (33.3%) were ART-eligible according to treatment criteria at the time; 115 (75.2% of those eligible) initiated ART (median = 12.86 weeks [95% CI: 9.75, 15.97] after linkage). In adjusted Cox proportional hazard models, internalized stigma was associated with a 65% decrease in the rate of ART initiation (Adjusted hazard ratio [AHR] 0.35, 95% CI: 0.19-0.80) during the period less than four weeks after linkage to care, but not four or more weeks after linkage to care, suggesting that stigma-reduction interventions implemented shortly after diagnosis may accelerate ART uptake. As reported by others, older age was associated with more rapid ART initiation (AHR for 1-year age increase: 1.04, 95% CI: 1.01-1.07) and higher CD4+ cell count (≥300µL vs. <150µL) was associated with a lower rate of initiation (AHR 0.38, 95% CI: 0.19-0.80). Several other factors that were assessed prior to diagnosis, including stronger belief in traditional medicine, higher endorsement of stigma toward people living with HIV, food insecurity, and higher psychological distress, were found to be in the expected direction of association with ART initiation, but confidence intervals were wide and could not exclude a null finding.

RESUMEN

There are currently no Food and Drug Administration-approved treatments for frontotemporal lobar degeneration (FTLD). The objectives of this study were to explore the tolerability of memantine treatment in FTLD and to monitor for possible effects on behavior, cognition, and function. Forty-three individuals who met clinical criteria for FTLD [21 with frontotemporal dementia (FTD), 13 with semantic dementia (SD), and 9 with progressive nonfluent aphasia (PA)] received 26 weeks of open-label treatment with memantine at a target dose of 20 mg daily. Concurrent treatment with acetylcholinesterase inhibitors was prohibited. Cognitive and functional outcome measures included the Mini Mental State Examination, Alzheimer's Disease Assessment Scale-Cognitive (ADAS-cog), clinical dementia rating-sum of boxes, Neuropsychiatric Inventory (NPI), Frontal Behavior Inventory, Executive Interview (EXIT25), Texas Functional Living Scale (TFLS), Geriatric Depression Scale, and Unified Parkinson's Disease Rating Scale-motor scale. Most subjects were able to tolerate the target dose of memantine. A transient improvement was observed on the total NPI score primarily in the FTD group. Variable declines were observed on the ADAS-cog, EXIT25, Frontal Behavior Inventory, NPI, TFLS, and UPDRS scores. The FTD and SD groups declined on most of the cognitive and behavioral outcome measures, but remained stable on the UPDRS, whereas the progressive nonfluent aphasia group remained relatively stable on the ADAS-cog, NPI, and TFLS, but declined on the UPDRS. Memantine was well-tolerated in these subjects. Future placebo-controlled trials of memantine in FTLD are warranted and may have greater power to detect behavioral and cognitive effects if focused on the FTD and SD clinical syndromes.

RESUMEN

Latinos in the U.S. are disproportionately affected by HIV and are more likely than non-Latinos to present with a late diagnosis, which delays engagement in HIV care and treatment. Social networks may provide normative influence and social support for HIV testing, but a contextualised understanding of networks is needed in order to maximise these social resources. We conducted qualitative interviews with foreign-born Latino men and transgender women (n = 17) in a new immigrant destination to explore their social networks. Most participants described having smaller social networks after migrating. Networks included both local and transnational ties, but most participants had few close ties. Contextual factors including stigma and geographic dispersion limited the re-construction of networks with close ties after migration. HIV testing was not a common topic of discussion with social network ties. Efforts to improve early uptake of HIV testing among Latino immigrants may benefit from engaging with social networks, but such efforts need to address how the context in which networks operate enables access to testing.

RESUMEN

BACKGROUND: Timely linkage to care by newly-diagnosed HIV+ individuals remains a significant challenge to achieving UNAIDS 90-90-90 goals. Current World Health Organization (WHO) guidelines recommend initiating anti-retroviral treatment (ART) regardless of CD4+ count, with priority given to those with CD4+ <350 cells/µl. We evaluated the impact of not having a day-of-diagnosis CD4+ count blood draw, as recommended by South African guidelines, on time to linkage, using data from a prospective cohort study. METHODS: Individuals (N = 2773) were interviewed prior to HIV counseling and testing at three public sector primary care clinics in the greater Durban area; 785 were newly-diagnosed and eligible for the cohort study; 459 (58.5%) joined and were followed for eight months with three structured assessments. Linkage to care, defined as returning to clinic for CD4+ count results, and day-of-diagnosis blood draw were self-reported. RESULTS: Overall, 72.5% did not have a day-of-diagnosis CD4+ count blood draw, and 19.2% of these never returned. Compared with a day-of-diagnosis blood draw, the adjusted hazard ratio of linkage (AHRlinkage) associated with not having day-of-diagnosis blood draw was 0.66 (95%CI: 0.51, 0.85). By 4 months, 54.8% of those without day-of-diagnosis blood draw vs. 75.2% with one were linked to care (chi-squared p = 0.004). Of those who deferred blood draw, 48.3% cited clinic-related and 51.7% cited personal reasons. AHRlinkage was 0.60 (95%CI: 0.44, 0.82) for clinic-related and 0.53 (95%CI: 0.38, 0.75) for personal reasons relative to having day-of-diagnosis blood draw. CONCLUSIONS: Newly-diagnosed HIV+ individuals who did not undergo CD4+ count blood draw on the day they were diagnosed-regardless of the reason for deferring-had delayed linkage to care relative to those with same-day blood draw. To enhance prompt linkage to care even when test and treat protocols are implemented, all diagnostic testing required before ART initiation should be performed on the same day as HIV testing/diagnosis. This may require modifying clinic procedures to enable overnight blood storage if same-day draws cannot be performed, and providing additional counseling to encourage newly-diagnosed individuals to complete day-of-diagnosis testing. Tracking HIV+ individuals via clinic registries should commence immediately from diagnosis to reduce these early losses to care.

RESUMEN

Research investigators often choose to euthanize mice by cervical dislocation (CD) when other methods would interfere with the aims of a research project. Others choose CD to assure death in mice treated with injected or inhaled euthanasia agents. CD was first approved for mouse euthanasia in 1972 by the AVMA Panel on Euthanasia, although scientific assessment of its humaneness has been sparse. Here we compared 4 methods of spinal dislocation--3 targeting the cervical area (CD) and one the thoracic region--in regard to time to respiratory arrest in anesthetized mice. Of the 81 mice that underwent CD by 1 of the 3 methods tested, 17 (21%) continued to breathe, and euthanasia was scored as unsuccessful. Postmortem radiography revealed cervical spinal lesions in 5 of the 17 cases of unsuccessful CD euthanasia. In addition, 63 of the 64 successfully euthanized mice had radiographically visible lesions in the high cervical or atlantooccipital region. In addition, 50 of 64 (78%) mice euthanized successfully had radiographically visible thoracic or lumbar lesions or both. Intentionally creating a midthoracic dislocation in anesthetized mice failed to induce respiratory arrest and death in any of the 18 mice subjected to that procedure. We conclude that CD of mice holds the potential for unsuccessful euthanasia, that anesthesia could be valuable for CD skills training and assessment, and that postmortem radiography has minimal promise in quality-control assessments.
