RESUMEN

Long Acting Injectable (LAI) therapy to treat HIV is an alternative to daily oral medications. The success of early roll-out of LAI to eligible patients requires a better understanding of patients' awareness and interest in this novel therapy. We administered an electronic survey to patients attending an urban HIV clinic in the US South. Eligible participants were 18 + years old with a most recent HIV-1 viral load < 200 copies/ml, without any evidence of genotypic resistance to LAI components or chronic hepatitis B. Survey recipients were asked about current treatment, engagement in care, and knowledge of LAI. Between January-April 2023, 480 patients were screened; 319 were eligible, and 155 (49%) completed the survey. The majority (119, 77%) were aware of, and 87 (56%) were interested in LAI. In regression analysis, only age was associated with interest in LAI (OR 0.95, 95% CI 0.92,0.99). Among proposed benefits of injectables, ease of travel without pills, lack of daily pill-taking, and fewer medication interactions were most appealing. Among proposed concerns with injectables, higher cost and insurance coverage of the new medicine were most worrisome. A large majority of people with HIV (PWH) are aware of the newest treatment available, and just over half of our sample expressed interest in LAI. Older age was associated with lower interest in LAI. LAI is appealing for its convenience, privacy, and avoidance of drug interactions, while the increased costs associated with LAI need to be addressed.

RESUMEN

BACKGROUND: People who inject drugs (PWID) are at high risk for opioid overdose and infectious diseases including HIV. We piloted PARTNER UP, a telemedicine-based program to provide PWID with medication for opioid use disorder (MOUD) with buprenorphine/naloxone (bup/nx) and oral pre-exposure prophylaxis (PrEP) with tenofovir disoproxil fumarate/emtricitabine through two syringe services programs (SSP) in North Carolina. We present overall results from this project, including participant retention rates and self-reported medication adherence. METHODS: Study participants met with a provider for an initial in-person visit at the SSP, followed by weekly telemedicine visits in month 1 and then monthly until program end at month 6. Participants were asked to start both MOUD and PrEP at initiation but could choose to discontinue either at any point during the study. Demographics and health history including substance use, sexual behaviors, and prior use of MOUD/PrEP were collected at baseline. Follow-up surveys were conducted at 3- and 6-months to assess attitudes towards MOUD and PrEP, change in opioid use and sexual behaviors, and for self-reported medication adherence. Participant retention was measured by completion of visits; provider notes were used to assess whether the participant reported continuation of medication. RESULTS: Overall, 17 persons were enrolled and started on both bup/nx and PrEP; the majority self-identified as white and male. At 3 months, 13 (76%) remained on study; 10 (77%) reported continuing with both MOUD and PrEP, 2 (15%) with bup/nx only, and 1 (8%) with PrEP only. At 6 months, 12 (71%) remained on study; 8 (67%) reported taking both bup/nx and PrEP, and 4 (33%) bup/nx only. Among survey participants, opioid use and HIV risk behaviors decreased. Nearly all reported taking bup/nx daily; however, self-reported daily adherence to PrEP was lower and declined over time. The most common reason for not continuing PrEP was feeling not at risk for acquiring HIV. CONCLUSIONS: Our study results show that MOUD and PrEP can be successfully administered via telemedicine in SSPs. PrEP appears to be a lower priority for participants with decreased continuation and adherence. Low perception of HIV risk was a reason for not continuing PrEP, possibly mitigated by MOUD use. Future studies including helping identify PWID at highest need for PrEP are needed. TRIAL REGISTRATION: Providing Suboxone and PrEP Using Telemedicine, NCT04521920.

RESUMEN

OBJECTIVES: The opioid overdose epidemic is escalating. Increasing access to medications for opioid use disorder in primary care is crucial. The impact of the US Department of Health and Human Services' policy change removing the buprenorphine waiver training requirement on primary care buprenorphine prescribing remains unclear. We aimed to investigate the impact of the policy change on primary care providers' likelihood of applying for a waiver and the current attitudes, practices, and barriers to buprenorphine prescribing in primary care. METHODS: We used a cross-sectional survey with embedded educational resources disseminated to primary care providers in a southern US academic health system. We used descriptive statistics to aggregate survey data, logistic regression models to evaluate whether buprenorphine interest and familiarity correlate with clinical characteristics, and a χ2 test to evaluate the effect of the educational intervention on screening. RESULTS: Of the 54 respondents, 70.4% reported seeing patients with opioid use disorder, but only 11.1% had a waiver to prescribe buprenorphine. Few nonwaivered providers were interested in prescribing, but perceiving buprenorphine to be beneficial to the patient population was associated with interest (adjusted odds ratio 34.7, P < 0.001). Two-thirds of nonwaivered respondents reported the policy change having no impact on their decision to obtain a waiver; however, among interested providers, it increased their likelihood of obtaining a waiver. Barriers to buprenorphine prescribing included lack of clinical experience, clinical capacity, and referral resources. Screening for opioid use disorder did not increase significantly after the survey. CONCLUSIONS: Although most primary care providers reported seeing patients with opioid use disorder, interest in prescribing buprenorphine was low and structural barriers remained the dominant obstacles. Providers with a preexisting interest in buprenorphine prescribing reported that removing the training requirement was helpful.

RESUMEN

Background: The COVID-19 pandemic has been a catalyst for telehealth services for people who use opioids; however, the data show dramatic increases in opioid overdose deaths and ongoing lack of treatment options in North Carolina, particularly among rural residents. Methods: We conducted a listening session and qualitative interviews with 10 health care professionals, administrators, and community partners providing services for individuals who use opioids in Granville and Vance counties. Data were analyzed with an applied thematic approach. Results: Participants described several benefits of rapid expansion of telehealth services during the pandemic. Continued improvements in access to high-speed internet will be critical to maintain progress in rural areas. Participants advocated for integrated, co-located ser-vices and improved referral processes to minimize cost and burden of attending multiple appointments across sites. Integrated services could include medication for opioid use disorder (MOUD), mental/behavioral health support, primary medical care, and harm reduction services. Participants supported novel community-based strategies, such as mobile clinics, and described a need for after-hours and crisis services for opioid recovery in the region. Limitations: The study was exploratory in nature and elicited the perspectives of providers serving two rural counties in North Carolina, which may not be generalizable to broader populations. We did not include the perspectives of people who use opioids in this study but will do so in upcoming research. Conclusions: Participants were strong proponents of the benefits of telehealth and identified strategies for continuing recent progress in rural access to opioid treatment through novel integrated and community-based approaches.

RESUMEN

Oral HIV pre-exposure prophylaxis (PrEP) is effective at preventing HIV. However, low adherence is common and undermines these protective effects. This is particularly relevant for groups with disproportionately higher rates of HIV, including Black men who have sex with men (MSM). The current study tested the feasibility, acceptability, and preliminary efficacy of a gamified mobile health contingency management intervention for PrEP adherence-called mSMART (Mobile App-Based Personalized Solutions for Medication Adherence of Rx Pill Tool). Fifteen Black MSM already prescribed PrEP in the community completed baseline and follow-up assessments separated by 8 weeks of using mSMART. Regarding feasibility, there was no study attrition, no mSMART functional difficulties that significantly interfered with use, and a mean rate of 82% daily mSMART use. Acceptability ratings were in the moderately to extremely satisfied range for factors such as willingness to recommend mSMART to others and user-friendliness, and in the low range for ratings on difficulty learning how to use mSMART. Scores on a system usability measure were in the acceptable range for 73% of the sample. Qualitative analysis of follow-up interviews identified individual components of mSMART that could be modified in future iterations to make it more engaging. PrEP composite adherence scores from biomarkers indicated an improvement from baseline to follow-up with a medium effect size, as well as a decrease in the number of perceived barriers to medication adherence. Findings indicate a future efficacy trial is needed to examine the effects of this gamified mobile health contingency management intervention on PrEP adherence.

RESUMEN

BACKGROUND: People who inject drugs (PWID) are at risk for HIV and opioid overdose. We piloted PARTNER UP, a telemedicine-based program to provide PWID with access to both oral pre-exposure prophylaxis (PrEP) for HIV prevention and medication for opioid use disorder (MOUD) through two syringe services programs (SSPs) in North Carolina. We conducted a qualitative evaluation to assess the acceptability and feasibility of PARTNER UP from the participant perspective. METHODS: PARTNER UP participants met with a provider for an initial in-person visit at the SSP, followed by weekly telemedicine visits in month 1 and then monthly telemedicine visits until program end at month 6. Using a qualitative descriptive study design, we conducted in-depth interviews with a subsample of PARTNER UP participants at 1 month and 4 months. Informed by the technology acceptance model, we assessed participant perceptions of the usefulness and ease of use of PARTNER UP, as well as their intent to continue to use the program's components. We audio-recorded all interviews with participants' permission and used applied thematic analysis to analyze the verbatim transcripts. RESULTS: We interviewed 11 of 17 people who participated in PARTNER UP-10 in the month 1 interview and 8 in the month 4 interview. Nearly all participants were motivated to join for consistent and easy access to buprenorphine/naloxone (i.e., MOUD); only a few joined to access PrEP. Most were comfortable accessing healthcare at the SSP because of their relationship with and trust toward SSP staff, and accessing services at the SSP was preferred compared with other healthcare centers. Some participants described that telemedicine allowed them to be honest and share more information because the visits were not in-person and they chose the location, although the initial in-person meeting was helpful to build provider trust and rapport. Most participants found the visit schedule to be feasible, although half described needing to reschedule at least once. Nearly all participants who were interviewed intended to continue with MOUD after the program ended, whereas none were interested in continuing with PrEP. CONCLUSIONS: Participant narratives suggest that the PARTNER UP telemedicine program was acceptable and feasible. Future studies should continue to explore the benefits of embedding both PrEP and MOUD into SSPs with larger numbers of participants. Trial registration Clinicaltrials.gov Identifier: NCT04521920.

RESUMEN

Pre-exposure prophylaxis (PrEP), a highly effective HIV prevention strategy, is currently underutilized by several at-risk groups, including both persons who inject drugs and those who use drugs via other routes. Stimulant use is associated with increased HIV risk due to both sexual and injection risk behaviors. In this study, we examined PrEP awareness and acceptability in persons with biologically confirmed HIV-negative status who use stimulant drugs. We also examined HIV risk behaviors to identify how many participants met behavioral eligibility for PrEP. The sample of 352 participants was 46% female, 87% African American, and 45.69 years old on average. Over half the sample (n = 213) met criteria for PrEP candidacy, but less than 20% had heard of PrEP. Ratings for willingness to take PrEP were high. PrEP candidates reported more frequent and problematic stimulant use relative to non-candidates. Our results show that persons who use stimulants are a high-risk population that could benefit significantly from PrEP. Efforts to increase PrEP awareness among high-risk populations are critical for facilitating PrEP implementation and ensuring effective HIV prevention within these communities.

RESUMEN

BACKGROUND: Despite young African American adults (ages 18-24) being among the highest risk groups for HIV infection, little is known about their awareness of HIV pre-exposure prophylaxis (PrEP) - a once daily pill shown to be > 90% effective in preventing HIV. To explore awareness and acceptability of PrEP among college students in this demographic, we conducted a survey of attendees at two large historically Black universities (HBCU) in North Carolina. METHODS: We administered a 14-item questionnaire to students at two HBCUs in North Carolina between February and April 2018. Questions were formatted in a yes/no or multiple choice format. Questionnaire items specifically addressed PrEP awareness and acceptability. Surveys were administered to students at a campus health fair and while transiting the campus student union via iPad. Response to all questions was optional. We fit a logistic regression model to determine association of key demographic determinants with PrEP acceptability and awareness. Statistical analyses were conducted using SAS 9.4 (SAS, Cary, NC). RESULTS: Overall, 210 students participated in the survey, of which 60 completed all survey items as presented. The survey cohort was 75% female, 89% heterosexual and 39% freshmen. The mean age of respondents was 19.8 years (SD: 1.8). Fifty-two percent of survey respondents reported that they were aware of PrEP prior to the time of survey administration. Only 3% of respondents reported that they were on PrEP. The most common sources of information on PrEP were campus health services (24%) and non-social media advertising (15%). Of respondents who were aware of PrEP, 61% reported that they had heard about in the 6 months prior to survey administration, while only 19% say they were aware of it for more than a year. Regarding acceptability of PrEP, 58% of respondents reported that they would take a once a day pill for HIV if they were at risk. Our logistic regression analysis found no statistically significant associations between key demographic factors and PrEP awareness. However, persons who perceived themselves to be at risk for HIV acquisition were more likely to find once daily oral PrEP (relative risk 2.66 (95% CI 1.31-5.42)) as an acceptable prevention strategy than the rest of the survey cohort. CONCLUSIONS: African American HBCU students are becoming aware of PrEP, and generally perceive the intervention as acceptable and worth consideration.

RESUMEN

BACKGROUND Adoption of HIV pre-exposure prophylaxis (PrEP) remains limited among populations at greatest risk for HIV acquisition. This study aims to assess awareness of PrEP among individuals in Durham, North Carolina, which has one of the highest rates of HIV diagnoses in the state.METHOD In 2015-2016, we administered a survey including questions to assess PrEP awareness to individuals at multiple venues throughout Durham, North Carolina.RESULTS A total of 139 respondents were surveyed. The majority were male (66%) and black/African American (75%); 21% were Hispanic/Latino. There were an estimated 53 men who have sex with men (MSM), of which 18 (33%) were black MSM M 24 years of age. Overall, only 53/138 (38%) respondents were aware of PrEP. Awareness was reported among 33/52 (63%) MSM respondents, 29/46 (63%) black MSM, and 10/17 (59%) black MSM M 24 years of age. In multivariate analysis, non-heterosexual orientation, health-insured status, and prior HIV testing were significantly associated with PrEP awareness. Ninety-four (69%) of 137 respondents reported prior HIV testing.LIMITATIONS Limitations include non-random sampling and limited sample size. Further research needs to be done in other areas of North Carolina, and assessment of PrEP acceptability and uptake needs to be performed.CONCLUSION This study reveals low overall awareness of PrEP in Durham, North Carolina, indicating that expanded outreach is necessary to increase public awareness and encourage adoption of PrEP among all demographics at risk for HIV.

RESUMEN

BACKGROUND: Although human immunodeficiency virus (HIV)-infected persons are at increased risk for major cardiovascular events, short-term prognosis after these events is unclear. METHODS: To determine the association between HIV infection and acute myocardial infarction (AMI) and stroke outcomes, we analyzed hospital discharge data from the Nationwide Inpatient Sample (NIS) between 2002 and 2012. Multivariable logistic regression was used to evaluate the association between HIV infection and in-hospital death after AMI or stroke. RESULTS: Overall, 18 369 785 AMI/stroke hospitalizations were included in the analysis. Patients with a history of AIDS were significantly more likely than uninfected patients to die during hospitalization after admission for AMI or stroke (odds ratio, 3.03 [95% confidence interval {CI}, 1.71-5.38] for AMI and 2.59 [95% CI, 1.97-3.41] for stroke). Additionally, patients with AIDS were more likely than HIV-uninfected patients to be discharged to nonhospital inpatient facilities after admission for AMI (OR, 3.14 [95% CI, 1.72-5.74]) or stroke (OR, 1.45; 95% CI, 1.12-1.87). There was a minimal difference in either outcome between HIV-infected patients without a history of AIDS and uninfected patients. CONCLUSIONS: Patients with a history of AIDS were significantly more likely than uninfected patients to die during hospitalization after admission for AMI or stroke. This disparity was not observed when infected patients without a history of AIDS were compared to uninfected patients, implying that preserving immune function may improve cardiovascular outcomes in HIV-infected persons.

RESUMEN

The genus Salvia, from the Lamiaceae family, has diverse biological properties that are primarily attributable to their diterpene contents. There is no comprehensive review on the molecular signaling pathways of these active components. In this review, we investigated the molecular targets of bioactive Salvia diterpenes responsible for the treatment of nervous and cardiovascular diseases. The effects on different pathways, including apoptosis signaling, oxidative stress phenomena, the accumulation of amyloid beta plaques, and tau phosphorylation, have all been considered to be mechanisms of the anti-Alzheimer properties of Salvia diterpenes. Additionally, effects on the benzodiazepine and kappa opioid receptors and neuroprotective effects are noted as neuropharmacological properties of Salvia diterpenes, including tanshinone IIA, salvinorin A, cryptotanshinone, and miltirone. Tanshinone IIA, as the primary diterpene of Salvia miltiorrhiza, has beneficial activities in heart diseases because of its ability to scavenge free radicals and its effects on transcription factors, such as nuclear transcription factor-kappa B (NF-κB) and the mitogen-activated protein kinases (MAPKs). Additionally, tanshinone IIA has also been proposed to have cardioprotective properties including antiarrhythmic activities and effects on myocardial infarction. With respect to the potential therapeutic effects of Salvia diterpenes, comprehensive clinical trials are warranted to evaluate these valuable molecules as lead compounds.

RESUMEN

BACKGROUND: Mitochondria play critical roles in both the life and death of cardiac myocytes. Pathogenic mitochondrial DNA (mtDNA) mutations leading to mitochondrial dysfunction can cause cardiomyopathies (CMPs). Our aim was to investigate the underlying mitochondrial defect in a patient with hypertrophic cardiomyopathy (hCMP). A detailed clinical and molecular genetic analysis was performed. PATIENTS AND METHODS: Total DNA was extracted from lymphocytes in a 14-year-old index male patient with hCMP, preexcitation syndrome, and severe ventricular arrhythmias. Direct sequencing of the PCR fragments was performed. To distinguish deleterious from functionally neutral variants, the ClustalW program, RNAfold software, and PolyPhen algorithm were applied, which predict the pathogenicity of a particular variant by using a set of empirical rules based on the nature of the mutation, the phylogenetic conservation of the variant, and the physicochemical property of the amino acid. RESULTS: The mutational analysis of mtDNA genes revealed four variants. The m.4395A>G transition (C6G) in the MT-TQ gene, which altered an evolutionary conserved nucleotide, with a conservation index of 85.7 % and affected a highly conserved U.G base pair in the secondary structure of MT-TQ. Additionally, the previously reported polymorphisms m.14757T>A, m.15236A>G, and m.15314G>A resulting in the replacement of amino acid residues in the MT-CYB gene were detected. CONCLUSION: The m.4395A>G variant was scored as possibly pathogenic and may exert a negative effect on heart function to generate hCMP.

RESUMEN

BACKGROUND: The cyclooxygenase-2 (cox-2) pathway is now recognized to be important in human cancer development and progression. The gene for cox-2 carries a common single nucleotide polymorphism, T8473C, located within a potential functional region in the 3'-UTR of cox-2 gene was identified. We have investigated the frequencies of cox-2 genotypes in Tunisian population to determine whether that polymorphism was associated with the risk of nasopharyngeal carcinoma (NPC) in Tunisian population. MATERIAL AND METHODS: One hundred and eighty-nine NPC patients were compared to 237 healthy controls. RESULTS: The cox-2 T8473C polymorphism was significantly associated with NPC (P=0.031). The CC-genotype and C allele were more frequent in control compared to patients group [CC: OR=0.37; P=0.013; 95% CI: 0.17-0.81; C: OR=0.72; P=0.032; 95% CI: 0.53-0.97]. Multivariate logistic regression analyses revealed that the CC-genotype was associated with a significantly decreased risk of NPC (P=0.013). Tumor sizes, histologic grade, presence of primary lymph node metastases, age or sex were not associated with cox-2 genotypes. CONCLUSION: We conclude that the CC-genotype and C allele of cox-2 T8473C gene polymorphism are associated with decreased risk of nasopharyngeal carcinoma in a Tunisian population.

RESUMEN

OBJECTIVE: To determine (a) the correlation between follicular sizes, oocyte maturity, normal fertilization rate, cleavage and embryo quality; and (b) to establish whether oocytes recovered with or without follicular flushing have different developmental competence. DESIGN: Prospective observational study. SETTING: Academic medical center. PATIENTS: Forty nine cycles (37 ICSI and 12 IVF). INTERVENTIONS: Measurement of 360 follicular diameters on the day of egg retrieval and classification into three groups Group A (mean diameter 12-14.5 mm.), group B (mean diameter 15-18 mm.) and group C (diameter >18.5 mm.). MAIN OUTCOME MEASURE: Correlation between follicular size at the time of retrieval and oocyte maturity, fertilization and cleavage rate in 226 oocytes (163 ICSI and 63 IVF). Developmental competence of oocytes retrieved with flushing versus non flushing. RESULTS: Almost all (99 %) of the oocytes recovered from follicles of group C were in metaphase II as opposed to 80 % in group A and 81 % in group B (p < 0.01). Overall there was a progressive and significant increase in fertilization rates from group A follicles to group C (47 % vs. 67 %, p 0.05). Overall 53 % of oocytes retrieved from group A follicles showed either no fertilization or abnormal fertilization versus 27 % in group C (p 0.05). The oocyte recovery rate with follicular flushing improved from group A to group B and to group C follicles (65 % vs. 49 % vs.37 % respectively p < 0.01). There were no differences in rates of immature oocyte, fertilization, abnormal or not fertilization and cleavage. CONCLUSIONS: The results of this study shows that: a) Follicles larger than 18 mm at retrieval have consistently mature oocytes with a higher rate of fertilization; b) Small size follicles are still capable of containing mature oocytes, but their rate of abnormal or no fertilization is high; c) Oocytes recovered with flushing are still able to produce embryos with full developmental competence.

RESUMEN

BACKGROUND: HIV, opioid use disorder (OUD), and mental health challenges share multiple syndemic risk factors. Each can be effectively treated with routine outpatient appointments, medication management, and psychosocial support, leading implementers to consider integrated screening and treatment for OUD and mental health in HIV care. Provider perspectives are crucial to understanding barriers and strategies for treatment integration. METHODS: We conducted in-depth qualitative interviews with 21 HIV treatment providers and social services providers (12 individual interviews and 1 group interview with 9 participants) to understand the current landscape, goals, and priorities for integrated OUD, mental health, and HIV care. Providers were purposively recruited from known clinics in Mecklenburg County, North Carolina, U.S.A. Data were analyzed using applied thematic analysis in the NVivo 12 software program and evaluated for inter-coder agreement. RESULTS: Participants viewed substance use and mental health challenges as prominent barriers to engagement in HIV care. However, few organizations have integrated structured screening for substance use and mental health into their standard of care. Even fewer screen for opioid use. Although medication assisted treatment (MAT) is effective for mitigating OUD, providers struggle to connect patients with MAT due to limited referral options, social barriers such as housing and food insecurity, overburdened staff, stigma, and lack of provider training. Providers believed there would be clear benefit to integrating OUD and mental health treatment in HIV care but lacked resources for implementation. CONCLUSIONS: Integration of screening and treatment for substance use and mental health in HIV care could mitigate many current barriers to treatment for all three conditions. Efforts are needed to train HIV providers to provide MAT, expand resources, and implement best practices.

RESUMEN

Introduction: HIV pre-exposure prophylaxis (PrEP) is largely underutilized in the Southern United States. Given their community presence, pharmacists are well positioned to provide PrEP within rural, Southern regions. However, pharmacists' readiness to prescribe PrEP in these communities remains unknown. Objective: To determine the perceived feasibility and acceptability of prescribing PrEP by pharmacists in South Carolina (SC). Methods: We distributed a 43-question online descriptive survey through the University of SC Kennedy Pharmacy Innovation Center's listerv of licensed SC pharmacists. We assessed pharmacists' comfort, knowledge, and readiness to provide PrEP. Results: A total of 150 pharmacists responded to the survey. The majority were White (73%, n=110), female (62%, n=93), and non-Hispanic (83%, n=125). Pharmacists practiced in retail (25%, n=37), hospital (22%, n=33), independent (17%, n=25), community (13%, n=19), specialty (6%, n=9), and academic settings (3%, n=4); 11% (n=17) practiced in rural locales. Pharmacists viewed PrEP as both effective (97%, n=122/125) and beneficial (74% n=97/131) for their clients. Many pharmacists reported being ready (60% n=79/130) and willing (86% n=111/129) to prescribe PrEP, although over half (62% n=73/118) cited lack of PrEP knowledge as a barrier. Pharmacists described pharmacies as an appropriate location to prescribe PrEP (72% n=97/134). Conclusions: Most SC pharmacists surveyed considered PrEP to be effective and beneficial for individuals who frequent their pharmacy and are willing to prescribe this therapy if statewide statutes allow. Many felt that pharmacies are an appropriate location to prescribe PrEP but lack a complete understanding of required protocols to manage these patients. Further investigation into facilitators and barriers of pharmacy-driven PrEP are needed to enhance utilization within communities.

RESUMEN

In this paper, we argue for the value of studying gender stereotypes at the subgroup level, combining insights from the stereotype content model, social role theory, and intersectional perspectives. Empirically, we investigate the stereotype content of gender subgroups in Norway, a cultural context for which a systematic description of stereotypes of gender subgroups is lacking. In a pilot study (n = 60), we established salient subgroups within the Norwegian context. Employing the stereotype content model, these groups were rated on warmth and competence in a main study (n = 191). Combining social role and intersectional perspectives, we compared stereotypes of women and men in the same social roles and social categories across subgroups. Comparisons between subgroups of women and men occupying the same social role indicated that at the subgroup level, women are often viewed as warmer than men, whereas the reverse appears to be a rare exception. Competence ratings, however, did not show this consistency. Our results at the subgroup level are consistent with research indicating that current gender stereotypes converge on constructs related to the competence dimension and remain divergent for constructs related to warmth.

RESUMEN

HIV pre-exposure prophylaxis (PrEP) is poorly utilized in the southern United States. We examined PrEP retention in care and sexually transmitted infections (STIs) through a retrospective review of the Duke University PrEP Clinic from January 1, 2015 to October 15, 2019. We evaluated short-term (3 months), long-term (additional 8-12 months), and longitudinal retention in care in our clinic. Adjusted odds ratios (aOR) were generated to explore demographics associated with retention. Kaplan-Meier curves were generated to view retention longitudinally. STIs were examined at baseline (1 year before initial PrEP visit) and while retained in care. Of a total of 255 patients; 88% were men, 37% were black, and 73% were men who have sex with men (MSM). Short- and long-term retention in care were met by 130/237 (55%) and 80/217 (37%) patients, respectively. MSM were more likely to be retained in the short term (aOR = 5.22, 95% confidence interval [CI] = 1.57-17.32). Self-referred patients were more likely to be retained in the long term (aOR = 2.18, 95% CI = 1.12-4.23). Uninsured patients were less likely to be retained in the long term (aOR = 0.32, 95% CI = 0.11-0.91). STI diagnoses include 42 infections at baseline and 69 infections during follow-up. STI diagnosed while in PrEP care was associated with longer retention in care over time. Patients discontinue PrEP care over time and STIs were frequently encountered. Additional studies are needed to determine the best way to retain patients in HIV preventative care.

RESUMEN

BACKGROUND: Underutilization of HIV pre-exposure prophylaxis (PrEP) in the Southern United States (US) is well-documented. Urgent care (UC) centers are positioned as communityfacing access points to PrEP, but the feasibility of integrating PrEP services into this setting is unclear. We conducted a survey of UC clinicians in the Southern US to better understand their perceptions of the feasibility of providing PrEP in their practice setting. OBJECTIVE: The study aims to determine the feasibility and acceptability of providing PrEP services in the UC setting through a cross-sectional survey of UC clinicians. METHODS: We conducted a 48-item cross-sectional survey of UC clinicians in the Southern US, between July and September 2020. The survey was distributed through the Urgent Care Association (UCA) and American Academy of Urgent Care Medicine (AAUCM) professional listservs as well as directly to publicly listed e-mail addresses. RESULTS: Eighty-two clinicians responded to the survey. Most clinicians had familiarity with PrEP (97%). All respondents rated PrEP as an effective way to prevent HIV. However, less than half felt UC facilities were an appropriate place to prescribe PrEP. Few respondents (8%) expressed doubts that expansion of PrEP access would decrease the incidence of HIV in their community. CONCLUSION: These findings show UC clinicians are familiar with PrEP, and many believe it would benefit their patients; however, provider opinions on the appropriateness of providing PrEP in the UC setting differ. Further studies on PrEP implementation in UC centers are needed.
