RESUMO
As the indications for endoscopic skull base approaches have increased, so has the need for more versatile vascularized flaps for skull base reconstruction. Here, we describe a novel lateral based nasopharyngeal flap (LNPF). Two cadaver heads were dissected to elucidate flap anatomy, dimensions, and technique. A retrospective review was performed on two cases where LNPF was used to repair CSF leaks in the nasopharyngeal area, and outcomes reported. The LNPF is an ascending pharyngeal artery myomucosal flap that includes the nasopharyngeal mucosa and the superior pharyngeal constrictor muscle. The flap was 1.2 × 2.2 cm in greatest dimensions. The LNPF was used for salvage CSF leak repair in two cases: one clival and one tubal. Both patients had resolution of leak at 7 months follow-up. The LNPF is a novel flap with reconstruction potential for the nasopharynx, including the lower clivus and the eustachian tube.
RESUMO
INTRODUCTION: Community-based cohort studies of HIV seroconversion can identify important avenues for enhancing HIV prevention efforts in the era of pre-exposure prophylaxis (PrEP). Within individuals, one can assess exposure and outcome variables repeatedly and with increased certainty regarding temporal ordering. This cohort study examined the association of several risk factors with subsequent HIV seroconversion. METHODS: We report data from a 4-year study (2017-2022) of 6059 HIV seronegative sexual and gender minority individuals who have sex with men who had indications for-, but were not using-, PrEP at enrolment. Participants completed repeat exposure assessments and self-collection of biospecimens for HIV testing. We examined the roles of race and ethnicity, socio-economic status, methamphetamine use and PrEP uptake over the course of follow-up in relation to HIV seroconversion. RESULTS: Over 4 years, 303 of the participants seroconverted across 18,421 person-years (incidence rate = 1.64 [95% CI: 1.59-1.70] per 100 person-years). In multivariable discrete-time survival analysis, factors independently associated with elevated HIV seroconversion risk included being Black/African American (adjusted risk ratio [aRR]: 2.44, 1.79-3.28), Hispanic/Latinx (1.53, 1.19-1.96), housing instability (1.58, 1.22-2.05) and past year methamphetamine use (3.82, 2.74-5.33). Conversely, time since study enrolment (24 vs. 12 months, 0.67, 0.51-0.87; 36 months, 0.60, 0.45-0.80; 48 months, 0.48, 0.35-0.66) and higher education (master's degree or higher vs. less than or equal to high school, 0.36, 0.17-0.66) were associated with reduced seroconversion risk. Compared to non-PrEP users in the past 2 years without a current clinical indication, those who started PrEP but then discontinued had higher seroconversion risk, irrespective of clinical indication (3.23, 1.74-6.46) or lack thereof (4.30, 1.85-9.88). However, those who initiated PrEP in the past year (0.14, 0.04-0.39) or persistently used PrEP in the past 2 years (0.33, 0.14-0.74) had a lower risk of seroconversion. Of all HIV seroconversions observed during follow-up assessments (12, 24, 36 and 48 months), methamphetamine was reported in the 12 months prior 128 (42.2%) times (overall). CONCLUSIONS: Interventions that acknowledge race and ethnicity, economic variables such as education and housing instability, and methamphetamine use are critically needed. Not only are interventions to engage individuals in PrEP care needed, but those that retain them, and re-engage those who may fall out of care are essential, given the exceptionally high risk of seroconversion in these groups.

Background: PrEP uptake among Black and Latino gay, bisexual, and other men who have sex with men (GBM) remains low in the United States. The design and implementation of PrEP delivery programs that incorporate the preferences of Black and Latino GBM may overcome barriers to uptake. We aimed to identify preferences for PrEP care among high-priority GBM in the U.S. with a large discrete choice experiment. Methods: We conducted two discreet choice experiments (DCE) to elicit care preferences for (1) Starting PrEP and (2) Continuing PrEP care among GBM clinically indicated for PrEP. The DCE web-based survey was nested in a longitudinal cohort study of GBM in the U.S., implemented with video and audio directions among 16-49 year-old participants, not using PrEP, and verified to be HIV-negative. All participants were presented with 16 choice sets, with choices determined by BLGBM and PrEP implementation stakeholders. We calculated overall utility scores and relative importance and used latent class analyses (LCA) to identify classes within the Starting and Continuing PrEP DCE. Multivariable analysis was performed to identify factors associated with class membership. Findings: Among 1514 participants, mean age was 32 years; 46·5% identified as Latino, 21·4% Black, and 25·2 White; 37·5% had an income less than USD $20,000. Two latent classes were identified for Starting PrEP: Class 1 (n=431 [28·5%]) was driven by preference for more traditional in-person care, and Class 2 (n=1083 [71·5%]) preferred flexible care options and on-demand PrEP. In a multivariable model, having a sexual health doctor (adjusted OR 0·7, CI 0·5, 0·9), having a primary care provider (OR 0·7,CI 0·5, 0·9, p= 0·023), and concerns over PrEP side effects (OR 1·1, CI 1·0,1·2, p= 0·003) were all associated with class membership. Interpretation: The different preferences identified for PrEP care indicate the need for diverse care and formulation choices to improve PrEP uptake and persistence. Addressing these preferences and understanding the factors that shape them can inform the implementation of programs that increase PrEP uptake.
RESUMO
Background: Youth, including those experiencing housing instability, are among the fastest growing groups of individuals with new STI diagnoses, including HIV. The unpredictable nature of the lives of youth experiencing housing instability often leads to inconsistent or non-existent health care and preventive follow up, leaving gaps in our knowledge about the most prominent needs for intervention. Methods: Using data from the Together 5000 (T5K) study, we examined factors associated with housing instability in a sample of 2,228 youth between the ages of 16-24 who identified as sexual and gender minority (SGM) men having sex with men. Logistic regression was used to assess the most prominent factors associated with housing instability. The model included seven significant factors - former peer victimization, gender, age, sex work, IPV, social support, and health insurance status. Findings: Participants who reported more behavioral risk factors for STI and those who reported sex work in the last three months were more likely to experience housing instability (OR = 2.5 and 2.76 respectively). Youth with higher levels of reported social support, health insurance, and older age were more likely to report stable housing (OR = .98, 1.61, and 1.13 respectively). Surprisingly, youth with stable housing were more likely to report intimate partner violence than those experiencing housing instability (OR = .89). Discussion: Implications for addressing STIs among adolescent SGM men having sex with men are discussed including bolstering support systems and addressing basic needs deficits and trauma associated with sex work and behavioral risk factors for STI. Implications and contributions statement: The study examines correlates of housing instability among a sample of young sexual and gender minority men who have sex with other men. Correlates of housing instability included behavioral risk factors for sexually transmitted infection and reporting sex work in the last three months. Health insurance, older age, and higher levels of social support were correlated with more stable housing.
RESUMO
Methamphetamine use is on the rise among sexual and gender minority people who have sex with men (SGMSM), escalating their HIV risk. Despite pre-exposure prophylaxis (PrEP) being an effective biomedical HIV prevention tool, its uptake in relation to methamphetamine use patterns in SGMSM has not been studied. In a U.S. cohort study from 2017 to 2022, 6,253 HIV-negative SGMSM indicated for but not using PrEP were followed for four years. Methamphetamine use was categorized (i.e., newly initiated, persistently used, never used, used but quit), and PrEP uptake assessed using generalized estimating equation (GEE), adjusted for attrition. Participants had a median age of 29, with 51.9% White, 11.1% Black, 24.5% Latinx, and 12.5% other races/ethnicities. Over the four years, PrEP use increased from 16.3 to 27.2%. GEE models identified risk factors including housing instability and food insecurity. In contrast, older age, health insurance, clinical indications, and prior PrEP use increased uptake. Notably, Latinx participants were more likely to use PrEP than Whites. Regarding methamphetamine use, those who newly initiated it were more likely to use PrEP compared to non-users. However, those who quit methamphetamine and those who persistently used it had PrEP usage rates comparable to those of non-users. Though PrEP uptake increased, it remained low in SGMSM. Methamphetamine use was associated with PrEP uptake. Healthcare providers should assess methamphetamine use for harm reduction. Prioritizing younger, uninsured SGMSM and addressing basic needs can enhance PrEP uptake and reduce HIV vulnerabilities.

Introduction: Pre-exposure Prophylaxis (PrEP) is a daily pill aimed at reducing HIV transmission risk when taken as prescribed. It's highly recommended for high-risk Men who have sex with Men (MSM). This study aimed to assess PrEP awareness and willingness to use it among Rwandan MSM, a critical aspect given PrEP's proven effectiveness. The findings are expected to inform policy decisions and further advance the implementation of PrEP strategies. Methods: This is a cross-sectional study design that utilized a web-based survey conducted between April and June 2019 to assess awareness and willingness to use PrEP among sexually active MSM in Rwanda. A snowball sampling technique was used to recruit participants via social media such as WhatsApp and e-mail. Eligibility criteria included being sexually active, aged ≥18 years, self-identifying as MSM, residing in Rwanda, self-reported engagement in receptive or insertive anal sex in the last 12 months, and self-reported HIV-negative serostatus. We assessed two primary outcomes: PrEP awareness (having ever heard of PrEP) and willingness to use PrEP within one month of completing the survey. Multivariable logistic regression was performed to identify participant characteristics associated with PrEP awareness and willingness to use it. Results: Out of 521 participants, the majority (73%) demonstrated awareness of PrEP. Factors linked to PrEP awareness included residing outside the capital, Kigali, being in the 18-29 age group, having higher education levels, perceiving a benefit from PrEP, and engaging in vaginal sex with a woman while using a condom in the last year. Additionally, 96% of participants expressed a strong willingness to use PrEP. Conclusion: Rwandan MSM exhibits a high level of PrEP awareness, notably associated with factors like location, age, education, perceived benefits, and condom use. The study also revealed a strong willingness to use PrEP, indicating promising prospects for its adoption among this group. These findings highlight the need for targeted awareness campaigns, personalized interventions, and comprehensive sexual health education to promote PrEP adoption and strengthen HIV prevention efforts among Rwandan MSM.

In the US, sexual and gender minority populations are disproportionately affected by HIV. Pre-exposure prophylaxis (PrEP) is a key prevention method, but its effectiveness relies on consistent usage. Our four-year national cohort study explored PrEP discontinuation among sexual and gender minority people who initiated PrEP. We found a high annual rate of discontinuation (35-40 percent) after PrEP initiation. Multivariable analysis with 6,410 person-years identified housing instability and prior history of PrEP discontinuation as predictors of discontinuation. Conversely, older age, clinical indication for PrEP, and having health insurance were associated with ongoing PrEP use. To promote sustained PrEP use, strategies should focus on supporting those at high risk for discontinuation, such as younger people, those without stable housing or health insurance, and prior PrEP discontinuers.

Lesbian, gay, bisexual, transgender, queer, and other sexual and gender minority (LGBTQ +) individuals experience bias in healthcare with 1 in 6 LGBTQ + adults avoiding healthcare due to anticipated discrimination and overall report poorer health status compared to heterosexual and cisgendered peers. The Society of General Internal Medicine (SGIM) is a leading organization representing academic physicians and recognizes that significant physical and mental health inequities exist among LGBTQ + communities. As such, SGIM sees its role in improving LGBTQ + patient health through structural change, starting at the national policy level all the way to encouraging change in individual provider bias and personal actions. SGIM endorses a series of recommendations for policy priorities, research and data collection standards, and institutional policy changes as well as community engagement and individual practices to reduce bias and improve the well-being and health of LGBTQ + patients.

Introduction: Pre-exposure Prophylaxis (PrEP) is a daily pill intended to reduce the risk of acquiring Human Immunodeficiency Virus (HIV) when taken as prescribed. It is strongly recommended for Men who have sex with Men (MSM) at high risk of HIV transmission to minimize infection risk. Despite its proven effectiveness, there is a lack of information about awareness and willingness to use PrEP among Rwandan MSM. In the context of HIV acquisition, the purpose of this study was to ascertain the awareness and willingness to use PrEP among high-risk Rwandan MSM. The findings of this research will provide valuable perspectives to mold policy and direct the effective execution of PrEP within the country. Method: This is a cross-sectional study design that utilized a web-based survey conducted between April and June 2019 to assess awareness and willingness to use PrEP among sexually active MSM in Rwanda. A snowball sampling technique was used to recruit participants who were contacted via social medial such as WhatsApp and e-mail. To be eligible, participants were supposed to be sexually active, aged ≥18 years, self-identify as MSM, residence in Rwanda, self-reported engagement in receptive or insertive anal sex in the last 12 months, and self-reported HIV-negative sero-status. We assessed two primary outcomes: PrEP awareness (having ever heard of PrEP) and willingness to use PrEP within one month of completing the survey. Multivariable logistic regression was performed to identify participant characteristics associated with PrEP awareness and willingness to use it. Results: Among the 521 participants included in the analysis, 63% were aged below 24 years. The majority (73%) demonstrated awareness of PrEP. Factors associated with PrEP awareness included residing outside of the capital, Kigali, as opposed to living in Kigali (adjusted odds ratio [aOR] 2.35, 95% confidence interval [CI] 1.40-3.97), being in the age groups 18-24 years (aOR 2.28, 95% CI: 1.03-5.01) or 25-29 years (aOR 3.06, 95% CI 1.35-6.93) compared to those aged 30 or older, having higher education levels, such as completing secondary education (aOR 1.76, 95% CI 1.01-3.06) or university education (aOR 2.65, 95% CI 1.18-5.96) in contrast to having no education. Lastly, perceiving a benefit from PrEP (aOR 9.52, 95% CI 4.27-21.22), and engaging in vaginal sex with a woman using a condom in the last 12 months (aOR 1.82, 95% CI 1.14-2.91) versus not. Impressively, 96% of participants expressed a strong willingness to use PrEP. Conclusion: Among Rwandan MSM, there is a high level of awareness of PrEP, notably associated with factors such as residing outside Kigali, younger age, higher education, perceived benefits of PrEP and condom use during vaginal sex in the past year. Furthermore, a significant portion of participants demonstrated an intense desire to use PrEP, suggesting promising possibilities for its extensive implementation among this group of people. The findings from this study emphasize the importance of implementing highly focused awareness campaigns, personalized intervention, and comprehensive sexual health education programs in order to enhance the adoption of PrEP and bolster HIV prevention initiatives among the Rwandan population of MSM.
RESUMO
Latinx sexual minority men (LSMM) face multilevel barriers to accessing HIV pre-exposure prophylaxis (PrEP). To address these barriers, we designed and implemented community-based organization (CBO)-PrEP, a collaborative community-based telehealth PrEP program for LSMM. We designed this PrEP delivery program through a collaborative process involving staff from local CBOs and a primary care-based HIV prevention program. Staff met weekly over a 3-month period to establish protocols for referrals, obtaining insurance coverage, and navigation to appointments and laboratory testing. To assess feasibility, we extracted electronic medical record data including demographics and clinical outcomes of PrEP care. Between December 2020 and May 2023, 102 individuals were referred to CBO-PrEP of which 85 had Hispanic/Latino as their ethnicity in their medical records; out of 102 individuals, 72 (70.6%) were scheduled for an initial appointment. Out of 72 individuals scheduled for an appointment, 58 (80.6%) were seen by a health care provider a median of 7.5 days after referral [interquartile range (IQR), 2-19]; 48 (82.6%) of initial appointments were through telemedicine, 10 (17.2%) were seen in person. Of the 48 patients who had a telehealth appointment, 36 (75%) underwent initial laboratory testing and 42 (87.5) were prescribed PrEP; all 10 patients who were seen in person underwent laboratory testing and were prescribed PrEP. PrEP prescriptions were received in a median of 17.5 days (IQR 4.5-33.5) after referral. CBO-PrEP successfully engaged LSMM, a population that is often hard to reach. Expanding collaborative approaches with CBOs could have a significant impact on improving PrEP uptake for LSMM and other priority populations.

In India and other low-and-middle-income countries, little is known about how intersectional stigma affects MSM engagement in ART. Informed by the Health Stigma and Discrimination Framework, we qualitatively examined how multiple stigmas influence ART engagement among Indian MSM. We conducted 3 focus groups (N = 22) with MSM living with HIV, aged 21-58 years, in Delhi and Hyderabad to identify potential intervention targets and solutions to improve treatment outcomes. Framework analysis and techniques were used to code and analyze translated audio-recordings. Findings revealed enacted stigma, associated with HIV and MSM identity, manifested as familial shame and healthcare discrimination, inhibiting access to support, and decreasing HIV care engagement. Anticipated stigma led to worry about disclosure and societal repercussions. Community-Based-Organizations, ART centers, and family members were primary sources of support, leading to increased ART initiation and retention. Potential solutions included using MSM peer-counselors, increasing social support, and providing HIV education to the general community.

Community-based organizations (CBOs) deliver services in culturally-responsive ways, and could effectively partner with health centers to deliver HIV pre-exposure prophylaxis (PrEP) to Latino men who have sex with men (LMSM). However, few such models exist. We conducted a planning study in collaboration with three CBOs serving LMSM to identify optimal PrEP delivery strategies for health centers and CBOs to implement jointly. We established a Community Expert Panel (CEP) of eight client-facing CBO and health center staff. Over 6 months, the panel met monthly to identify collaborative strategies for PrEP delivery, using a modified Delphi method consisting of the following steps: (1) brainstorming strategies; (2) rating strategies on acceptability, appropriateness and feasibility; (3) review of data from qualitative focus group discussions with CBO clients; and (4) final strategy selection. The panel initially identified 25 potential strategies spread across three categories: improving communication between health centers and CBOs; using low-barrier PrEP options (e.g. telemedicine), and developing locally-relevant, culturally-sensitive outreach materials. Focus groups with CBO clients highlighted a desire for flexible options for PrEP-related care and emphasized trust in CBOs. The final package of strategies consisted of: (1) a web-based referral tool; (2) telemedicine appointments; (3) geographically-convenient options for lab specimen collection; (4) tailored print and social media; and (5) regular coaching sessions with CBO staff. Through a community-engaged process, we identified a package of PrEP delivery strategies that CBOs and health centers can implement in partnership, which have the potential to overcome barriers to PrEP for LMSM.

BACKGROUND: Young Black and Latino men who have sex with men (YBLMSM) have the highest rates of new HIV infections in the USA and use PrEP at lower rates than White MSM. OBJECTIVE: To explore YBLMSM's perspectives and experiences of PrEP use to identify factors enabling or impeding uptake. DESIGN: Qualitative study using semi-structured interviews conducted between August 2015 and April 2016. PARTICIPANTS: Black and Latino MSM, 18-20 years of age, who live, socialize, or work in the Bronx, and were fluent in English or Spanish. APPROACH: We used a thematic analysis to identify themes related to not taking PrEP and PrEP uptake. KEY RESULTS: Half the participants (n = 9) were currently using PrEP, a majority had Medicaid (n = 13), all reported having a PCP, all identified English as their primary language (n = 15), and all identified as gay. Salient themes included concerns over-side effects, stigma related to HIV and sexuality, mistrust of medical providers, provider's refusal to prescribe PrEP, and insurance and cost. CONCLUSIONS: Modifiable barriers for PrEP uptake and persistence were reported by most participants, with an emphasis on PrEP misinformation and the pervasiveness of intersectional stigma, providers' low awareness, and hesitant attitudes towards PrEP and barriers created by insurance companies. Supportive infrastructures for PrEP providers and patients are needed.

BACKGROUND: With genetic testing advancements, the burden of incidentally identified cardiac disease-associated gene variants is rising. These variants may carry a risk of sudden cardiac death, highlighting the need for accurate diagnostic interpretation. We sought to identify pathogenic hotspots in sudden cardiac death-associated genes using amino acid-level signal-to-noise (S:N) analysis and develop a web-based precision medicine tool, DiscoVari, to improve variant evaluation. METHODS: The minor allele frequency of putatively pathogenic variants was derived from cohort-based cardiomyopathy and channelopathy studies in the literature. We normalized disease-associated minor allele frequencies to rare variants in an ostensibly healthy population (Genome Aggregation Database) to calculate amino acid-level S:N. Amino acids with S:N above the gene-specific threshold were defined as hotspots. DiscoVari was built using JavaScript ES6 and using open-source JavaScript library ReactJS, web development framework Next.js, and JavaScript runtime NodeJS. We validated the ability of DiscoVari to identify pathogenic variants using variants from ClinVar and individuals clinically evaluated at the Duke University Hospitals with cardiac genetic testing. RESULTS: We developed DiscoVari as an internet-based tool for S:N-based variant hotspots. Upon validation, a higher proportion of ClinVar likely pathogenic/pathogenic variants localized to DiscoVari hotspots (43.1%) than likely benign/benign variants (17.8%; P<0.0001). Further, 75.3% of ClinVar variants reclassified to likely pathogenic/pathogenic were in hotspots, compared with 41.3% of those reclassified as variants of uncertain significance (P<0.0001) and 23.4% of those reclassified as likely benign/benign (P<0.0001). Of the clinical cohort variants, 73.1% of likely pathogenic/pathogenic were in hotspots, compared with 0.0% of likely benign/benign (P<0.01). CONCLUSIONS: DiscoVari reliably identifies disease-susceptible amino acid residues to evaluate variants by searching amino acid-specific S:N ratios.

Disparities in HIV incidence and PrEP uptake suggest a need to prioritize Black sexual minority men (SMM) in PrEP social marketing initiatives. However, images linking Black SMM to HIV and PrEP may inadvertently reinforce stigma. We examined HIV-negative/status-unknown Black SMM's responses to targeted PrEP advertisements using mixed methods, including an experiment embedded in a longitudinal online survey (Time 1: n = 96; Time 2 [eight weeks]: n = 73) and four focus groups (n = 18). The full factorial experiment included between-groups and within-subjects comparisons. For between-groups comparisons, each participant was randomly assigned to view one of 12 advertisements, which varied by couple composition (Black SMM couple/Black heterosexual couple/multiple diverse couples/no couples) and campaign (PrEPare for the Possibilities/PlaySure/PrEP4Love). We examined couple composition, campaign, and interaction effects on: advertisement judgments (Time 1), PrEP stigma (Time 1), PrEP motivation (Times 1 and 2), and PrEP behavior (Time 2). For within-subjects comparisons, each participant viewed all 12 advertisements, and we examined couple composition, campaign, and interaction effects on advertisement judgments (Time 2). Focus group participants discussed advertising preferences and responded to the same set of advertisements. For between-groups and within-subjects comparisons, we found significant couple composition effects but no or limited campaign and interaction effects on advertisement judgments. Advertisements featuring Black SMM exclusively were judged as more stigmatizing than advertisements without couples. Advertisements with diverse (vs. no) couples were considered more eye-catching and motivating. There were minimal effects of couple composition and campaign on PrEP stigma, motivation, and behavior. Focus group participants corroborated concerns about the potential for PrEP advertisements to be stigmatizing, suggesting advertisements featuring Black SMM exclusively could be alienating and fuel conspiracy theories. Focus group participants generally favored diverse and less sexualized advertisements, particularly for public spaces. Findings collectively highlight the potential for targeted PrEP advertisements to stigmatize Black SMM and support diverse representation.

Online outreach may be an important strategy to reach Indian gender minority (GM) populations for HIV testing. However, little is known about Indian GM populations reached online who are sexually active and their HIV testing behaviors. We conducted a secondary analysis of an India wide online cross-sectional survey to assess HIV testing and identify associated factors. The 467 GM respondents identified their gender as transgender women (29.6%), Hijra (5.1%), intersex (37%), or gender non-binary (28.3%). Overall, almost half (47.5%) had never been tested for HIV; among respondents having condomless anal sex, half (50%) reported never testing for HIV. A decreased odds of ever HIV testing was associated with being unsure how to access free testing (compared to being easy; AOR = 0.36, 95%CI 0.20, 0.63) and unaware of comfortable testing sites (AOR = 0.32, 95% CI 0.20, 0.63). Increased odds of testing were associated with identifying as Hijra (compared to transgender women; AOR = 4.07, 95%CI 1.18-16.92) and disclosing sexual behaviors to a doctor (AOR = 3.20, 95% CI 1.91, 5.46). In this GM sample recruited online, HIV testing rates were low. Online interventions are needed to engage individuals with diverse GM identities in India for linkage to accessible and acceptable HIV testing options.
