RESUMO
Exosomes, or extracellular vesicles, represent the latest cell-free addition to the regenerative medicine toolkit. In vitro preclinical studies have demonstrated the safety and efficacy of exosomes, which vary based on source and biomanufacturing, for a myriad of potential therapeutic applications relevant to skin and soft tissue reconstruction. Primary search was performed in September 2021 on the MEDLINE database via PubMed and Ovid, with focus on articles about therapeutic application of exosomes or extracellular vesicles. In total, 130 articles met criteria for applicability, including early-stage clinical trials, preclinical research studies with in vivo application, and articles applicable to plastic and reconstructive surgery and dermatology. Most studies used animal models of human disease processes, using either animal donor cells to isolate exosomes, or human donor cells in animal models. Exosome technology has catapulted as an acellular therapeutic vehicle with off-the-shelf accessibility. These features eliminate prior threshold for broad adoption of regenerative cell-based therapies into surgical and medical practice. To date, there are no exosome products approved by the US Food and Drug Administration. This review highlights exosomes as the new frontier in regenerative medicine and outlines its preclinical therapeutic applications for cutaneous repair and restoration.
RESUMO
BACKGROUND: The transition to the "test-and-treat" policy in Nepal in 2017, coupled with the rapid initiation of antiretroviral therapy (ART) in 2020, necessitates an in-depth understanding of factors influencing ART initiation and retention. This study investigates these factors from the perspectives of healthcare providers, families/communities, and people living with HIV (PLHIV). METHODS: Employing a qualitative design, in-depth interviews were conducted with 24 ART clients and 26 healthcare providers across different provinces of Nepal. A comprehensive interview guide facilitated the exploration of experiences and perceptions. Interviews were transcribed verbatim, and thematic analysis was applied to distill key insights. Guided by a socio-ecological model, interviews were analyzed to identify the barriers and facilitators to ART initiation and continuation at the individual, family/community, and health system levels. RESULTS: Facilitators and barriers were identified at three levels. Individual-level facilitators included fear of death, perceived health benefits, knowledge about HIV/ART, confidentiality, and financial support. Barriers encompassed concerns about lifelong medication, side effects, denial of HIV status, fear of disclosure, and financial constraints. At the family/community level, support from family and community health workers facilitated ART adherence, while social stigma and discrimination posed barriers. The health system's role was dual; the provision of free treatment, a client tracking system and a robust drug supply chain were facilitators, whereas logistical challenges and service accessibility during the COVID-19 pandemic were notable barriers. CONCLUSIONS: This study highlights the various factors that influence ART initiation and retention in Nepal during the test-and-treat era. Tailored interventions should focus on increasing awareness about HIV and ART, strengthening healthcare systems, ensuring availability of medications, and providing accessible treatment during service disruptions. Furthermore, these interventions should encourage supportive environments at the individual, community, and healthcare system levels. Taking this holistic approach is essential for effectively implementing ART and achieving long-term health outcomes in light of changing public health policies.

Background: Young gay, bisexual, and other men who have sex with men (YMSM) in Latin America experience disproportionately high rates of HIV. While new case numbers have stabilised in other demographics, the incidence of HIV in this particular group continues to rise. We estimated the prevalence of HIV and sexually transmitted infections (STI) and identified correlates of new HIV diagnoses among YMSM in Brazil. Methods: Conectad@s was a respondent-driven sampling-based study to recruit and engage YMSM in HIV prevention and treatment services in Rio de Janeiro, Brazil (November 2021-October 2022). Eligibility criteria were age 18-24 years and self-identification as MSM (cis/trans) or non-binary person who have sex with men. Participants underwent HIV/STI testing and completed a socio-behavioural questionnaire. We described baseline characteristics by HIV status and used logistic regression models to identify correlates of new HIV diagnoses. Trial ID: DERR1-10.2196/34885. Findings: Among 409 participants, 370 (90.5%) self-identified as cisgender men, nine (2.2%) transgender men, and 30 (7.3%) non-binary. Median age was 21 years (IQR: 20-23), with 80 (19.6%) aged 18-19 years. Most self-identified as Black or Pardo (70.6%); 109 (26.7%) never tested for HIV. HIV prevalence was 9.8%; 50% (n = 20/40) were newly diagnosed with HIV. Only nine participants ever used PrEP and three were currently using it. Overall, 133 (32.5%) reported sexual violence in their lifetime and 102 (24.9%) reported a suicide attempt. Prevalence of active syphilis, chlamydia, and gonorrhoea were 14.4%, 15.9%, and 14.7%, respectively. New HIV diagnoses were positively associated with engaging in high-risk behaviour (aOR 4.88 [95% CI: 1.88-13.40]) and anxiety (aOR 2.67 [95% CI: 1.01-7.70]), and negatively associated with ever disclosing sexual orientation (aOR 0.19 [95% CI: 0.04-0.92]) and HIV knowledge (aOR 0.77 [95% CI: 0.59-1.01]). Interpretation: High prevalence of HIV coupled with a high proportion of new HIV diagnoses underscore a potentially growing HIV epidemic among YMSM in Brazil. Funding: National Institutes of Health (NIH), Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) and Ministry of Health of Brazil.
RESUMO
Introduction: Little is known about differences in HIV risk for trans women by partner gender, particularly with respect to social determinants and partner-level circumstances that affect behavior. We examined differences in demographic, social determinants, and HIV-related risk behaviors for trans women with cis men and trans women sexual partners. Materials and Methods: Data are from a cross-sectional survey of trans women and their sexual partners conducted between April 2020 and January 2021. Interviews were held remotely during shelter-in-place due to Covid-19 via videoconference. Analysis characterizedassociations between HIV risk and protective behaviors comparing trans women with cisgender men partners to trans women with non-cisgender sexual partners. Results: A total of 336 sexual partners were identified from 156 trans women. Trans women with cis men partners had significantly less education and employment and more incarceration and recidivism than trans women with trans women partners. Trans women and their cisgender men partners had shared experiences of unstable housing, incarceration, and HIV. Trans women with cisgender men partners reported significantly more sex exchange partners, receptive condomless sex, receptive or insertive condomless sex while using substances, and HIV infection compared to trans women with trans women partners. Conclusions: Trans women with cisgender men sexual partners faced higher HIV risk than trans women with trans women sexual partners. These risks may be related to the social and economic drivers that both trans women and their cis men partners faced, including barriers to education and employment, along with incarceration and recidivism. Interventions focused on economic stability, workforce development and post incarceration re-entry support for housing and employment for trans women with cis men partners and the cisgender men partners as well may have the most impact on reducing HIV risk and incidence.
RESUMO
We aimed to estimate the proportions of childhood parental neglect, abuse, and rejection and to evaluate the co-occurrence of these experiences among transgender women in Rio de Janeiro, Brazil. This was a cross-sectional study with a convenience sample enrolled between July 2019 and March 2020, using an adapted version of the Childhood Trauma Questionnaire. Proportions and corresponding confidence intervals (CI) were calculated. Kendall correlation with Tau-b estimator was used in the bivariate analyses. We gathered data from 139 participants. The most prevalent types of childhood traumas were emotional abuse (60.43%, 95% CI [51.79, 68.62]), physical abuse (57.55%, 95% CI [48.90, 65.89]) and sexual abuse (44.60%, 95% CI [36.18, 53.27]). Severe to extreme physical and emotional abuse occurred among 40.29% (95% CI [32.06, 48.93]) and 5.75% (95% CI [2.51, 11.02]) of participants, respectively. The proportion of parental rejection (eviction) was 32.37% (95% CI [25.04, 40.69]) and occurred with the other forms of abuse, except sexual abuse. Multiple types of childhood abuse, neglect, and parental rejection were observed among transgender women in our sample. The harmful effects of childhood abuse on the mental and physical health of people in the transgender population are of concern, particularly considering the cumulative effect produced by the co-occurrence of such events and their harmful lifetime effects. It is urgently necessary to debate and formulate public policies to ensure the right to gender expression from childhood.
RESUMO
BACKGROUND: Young adult (18-30 years) people who inject drugs (PWID) face high hepatitis C virus (HCV) prevalence. In San Francisco, where >60% of PWID lack stable housing, barriers hinder HCV treatment access. We assessed progress towards the World Health Organization's (WHO) HCV elimination goal of an 80% reduction in incidence over 2015-2030, focusing on young (YPWID) and unstably housed PWID in San Francisco. METHODS: We developed a dynamic HCV transmission model among PWID, parameterized and calibrated using bio-behavioural survey datasets from San Francisco. This included 2018 estimates for the antibody-prevalence among PWID (77%) and care cascade estimates for HCV for YPWID (72% aware of their status and 33% ever initiating treatment). Based on programmatic data, we assumed a 53.8% reduction in testing and 40.7% decrease in treatment from 2020 due to the COVID-19 pandemic, which partially rebounded from April 2021 with testing rates then being 31.1% lower than pre-pandemic rates and treatment numbers being 19.5% lower. We simulated different scenarios of how services changed after the pandemic to project whether elimination goals would be met. RESULTS: Continuing post-pandemic rates of testing and treatment, the model projects an 83.3% (95% credibility interval [95% CrI]:60.6-96.9%) decrease in incidence among PWID over 2015-2030 to 1.5/100pyrs (95% CrI:0.3-4.4) in 2030. The probability of achieving the elimination goal by 2030 is 62.0%. Among YPWID and unstably housed PWID, the probability of achieving the elimination goal by 2030 is 54.8 and 67.6%, respectively. Importantly, further increasing testing and treatment rates to pre-pandemic levels by 2025 only results in a small increase in the probability (67.5%) of the elimination goal being achieved among all PWID by 2030, while increased coverage of medication for opioid use disorder among YPWID and/or housing interventions results in the probability of achieving elimination increasing to over 75%. CONCLUSION: The COVID-19 pandemic impeded progress toward achieving HCV elimination. Our findings indicate that existing partial rebounds in HCV testing and treatment may achieve the elimination goal by 2030, with an additional scale-up of interventions aimed at YPWID or unstably housed PWID ensuring San Francisco is likely to achieve elimination by 2030.
RESUMO
People who are structurally disadvantaged and marginalized often report poor health care experiences, such as inequitable treatment, due to intersecting forms of stigma and discrimination. There are many measures of patient experiences of care, however, few are designed to measure equity-oriented health care. In alignment with ongoing calls to integrate actions in support of health equity, we report on the development and testing of patient-reported experience measures that explicitly use a health equity and intersectional lens. Our analysis focuses on two different scales: the Equity-Oriented Health Care Scale-Ongoing, which was evaluated in primary health care settings where patients have an ongoing relationship with providers over time, and the Equity-Oriented Health Care Scale-Episodic, which was tested in an emergency department where care is provided on an episodic basis. Item Response Theory was used to develop and refine the scales. The psychometric properties of each scale were also evaluated. The Equity-Oriented Health Care Scale-Ongoing was first tested with a cohort of 567 patients. The Equity-Oriented Health Care Scale-Episodic was subsequently tested in an emergency department setting with 284 patients. Results of the Item Response Theory analysis for each scale yielded a brief index that captured the level of equity-oriented care when care is ongoing (12 items) or episodic (9 items). Both scales showed evidence of internal consistency and concurrent validity, based on a high correlation with quality of care. They are brief, easy-to-administer patient-reported experience measures that can support organizations to monitor quality of care. Their availability enhances the possibility of measuring equity-oriented health care in diverse contexts and can provide nuanced understandings of quality of care through an intersectional and equity lens.

HIV disproportionately affects Black/African Americans (AA), while PrEP is under-utilized by Black/AA, women, and people who inject drugs (PWID). In San Francisco, California's National HIV Behavioral Surveillance among PWID in 2022, Black/AA women were the least likely to be tested for HIV among all groups by sex and race/ethnicity and the least likely to be aware of PrEP among women. Yet, Black/AA women were no less likely to see a healthcare provider in the last year. Data suggest that providers' failure to discuss and address HIV risk with Black/AA female PWID is a major barrier to accessing effective care and prevention. El VIH afecta de manera desproporcionada a Black/afroamericanos (AA), mientras que la PrEP está infrautilizada por los Black/AA, las mujeres y las personas que se inyectan drogas (PWID). En la National HIV Behavioral Surveillance de PWID de San Francisco, California en 2022, las mujeres Black/AA eran las que menos probabilidades tenían de someterse a la prueba del VIH entre todos los grupos por sexo y raza/etnia y las que menos probabilidades tenían de conocer la PrEP entre las mujeres. Sin embargo, las mujeres Black/AA no tenían menos probabilidades de acudir a un profesional sanitario en el último año. Los datos sugieren que el hecho de que los proveedores no hablen ni aborden el riesgo de VIH con las PWID de raza Black/AA es un obstáculo importante para acceder a una atención y prevención eficaces.

Clinical trials provide evidence that pre-exposure prophylaxis (PrEP) prevents HIV acquisition including through sharing of injection equipment among people who inject drugs (PWID). However, uptake among many populations at risk for HIV has been slow, particularly among PWID. We examined data from the National HIV Behavioral Surveillance (NHBS) from San Francisco in 2022 to measure PrEP uptake and identify factors associated with PrEP awareness among PWID. Of 479 PWID with HIV-negative or unknown HIV status, 54.9% were aware of PrEP, 5.9% had discussed PrEP with a healthcare provider, and 1.5% had used PrEP in the past year. Lack of PrEP awareness was associated with being age 50 years and older (adjusted odds ratio [aOR] 0.40, 95% CI 0.27-0.60), being men who have sex with women (vs. men who have sex with men, aOR 0.47, 95% CI 0.24-0.92), having a disability (aOR 0.58, 95% CI 0.35-0.95), using heroin as their most frequently injected drug (aOR 0.51, 95% CI, 0.34-0.78), not having tested for HIV, HCV, or an STD in the past year (aOR 0.43, 95% CI 0.28-0.64), and not having access to new sterile needles in the past year (aOR 0.28, 95%CI 0.08-1.00). We found negligible change in the awareness and uptake of PrEP among PWID since previously measured in NHBS in 2018. Low PrEP use among PWID may be addressed by increasing provider discussion of PrEP with their PWID patients and clients during routine care, expanding testing for injection-related infections among PWID, and integrating PrEP access into harm reduction programs.

BACKGROUND: Many adolescents and young adults (AYAs; 10-24 years old) are excluded from HIV research because of social, ethical, and legal challenges with informed consent, resulting in limited AYA-focused data. We use a participatory approach to identify strategies for improving AYA consent processes in HIV research in low- and middle-income countries (LMICs). METHODS: We conducted a digital crowdsourcing open call for ideas to improve AYA consent to HIV research in LMICs. Crowdsourcing involves engaging a group of people in problem-solving, then sharing emergent solutions. Submissions were evaluated by 3 independent judges using predefined criteria, with exceptional strategies receiving prizes. Demographic data were collected, and textual data were qualitatively analyzed for emergent themes in barriers and facilitators for improving AYA consent in HIV research, guided by a socioecological model. RESULTS: We received 110 strategies total; 65 were eligible for evaluation, 25 of which were identified as finalists. Fifty-eight participants from 10 LMICs submitted the 65 eligible submissions, of which 30 (52%) were 18 to 24 years old. Thematic analysis identified 10 barriers to AYA consent, including HIV stigma, limited education, and legal/regulatory barriers. Strategies for improving AYA consent processes revealed 7 potential facilitators: enhancing AYA engagement in research, involving parents/guardians, improving education/awareness, improving institutional practices/policy, making research participation more AYA-friendly, enhancing engagement of other key communities of interest, and empowering AYA. CONCLUSIONS: Diverse communities of interest in LMICs developed compelling strategies to enhance informed consent that may improve AYA inclusion in HIV research. These data will be used to develop practical guidance on improving AYA consent processes.

Context: Staff in Canadian Emergency Departments (EDs) face increasing workplace demands arising in part from system-wide shortages in primary and community care. Patients experiencing stigmatizing conditions such as chronic pain, substance use, and psychiatric disorders may turn to the ED as the only open "door" to access care in the community. Objective: To examine staff perceptions about their work and role, including how they may be prepared or not to address issues of health and health care inequities in EDs. Study Design and Analysis: Paper and online surveys were administered to staff. Data were collected as part of a larger mixed-methods organization-level intervention study aimed at enhancing capacity to provide equity-oriented health care in EDs. Pooled, cross-sectional survey data (n=393) were analyzed to examine work experiences, team effectiveness, and domains of equity- oriented care. Descriptive results from survey data are complemented by illustrative excerpts from qualitative interviews conducted with staff and administrative leadership. Setting: Three EDs in British Columbia. Population Studied: All staff working in EDs participating in the EQUIP ED study. Intervention: N/a. Outcome Measures: N/a. Results: Levels of stress, the extent of control over work, sufficient time to complete work, receive feedback about work, and ratings of the quality of care provided in the ED highlight workplace pressures, constraints, and impact on staff. The proportion of staff who have received training on and have confidence in being able to provide equity-oriented care in the ED has implications for how staff may be able to contribute to improved care for patients already experiencing the harmful effects of stigma and other forms of discrimination including fragmentation of care. Conclusions: The impacts of shortages in primary care reverberate throughout the system. EDs often prioritize efficiency, a focus which cannot adequately equip staff to promote equity. Attention and commitment to addressing structural inequities within EDs could support patients and staff to move closer to the quintuple aim.

BACKGROUND: Substance use and mental distress are known barriers to HIV care engagement among trans women. Less is known about access and utilization of mental health and substance use care among trans women and the relationship between unmet behavioral health needs and HIV viral suppression. We examined the relationship between mental health and substance use on HIV viral load among trans women living with HIV. We also examined the relationship between mental health and substance use services needs with HIV care engagement and having a detectable viral load by comparing engagement in care cascades. METHODS: Data are from a 2022 baseline assessment for an intervention with trans women living with HIV (n = 42) in San Francisco. Chi-Squared or Fisher's exact tests were conducted to determine associations between HIV viral load, mental health, and substance use. We also examine characteristics associated with each step in the HIV, mental health, and substance use care cascades. RESULTS: Most participants were trans women of color (85.7%), 40 years of age or older (80.9%), with low income (88.1%), and almost half were unstably housed (47.6%). Of the 32 participants who screened positive for depression, anxiety and/or psychological distress, 56.3% were referred for mental health services in the past 12 months. Of those who were referred, 44.4% received mental health services. Of the 26 participants who screened positive for a substance use disorder, 34.6% were referred to substance use services in the past 12 months. Of those referred, 33.3% received substance use services in the past 3 months. Latina trans women had a low referral rate to meet their mental health needs (50%) and only 16.7% of African American/Black trans women who screened positive for a substance use disorder were referred for services, while trans women of other race/ethnicities had high referral and services utilization. No significant results were found between HIV viral load and screening positive for a mental health disorder. Methamphetamine use was statistically associated with having a detectable HIV viral load (p = 0.049). CONCLUSIONS: We identified significant unmet mental health and substance use services needs and noted racial/ethnic disparities in the context of high HIV care engagement among trans women living with HIV. We also found that methamphetamine use was a barrier to having an undetectable viral load for trans women living with HIV. To finally end the HIV epidemic, integration of behavioral health screening, linkage, and support are needed in HIV care services for populations most impacted by HIV, especially trans women. TRIAL REGISTRATION: NCT, NCT 21-34,978. Registered January 19, 2022.

The rapid increase of the potent greenhouse gas methane in the atmosphere creates great urgency to develop and deploy technologies for methane mitigation. One approach to removing methane is to use bacteria for which methane is their carbon and energy source (methanotrophs). Such bacteria naturally convert methane to CO2 and biomass, a value-added product and a cobenefit of methane removal. Typically, methanotrophs grow best at around 5,000 to 10,000 ppm methane, but methane in the atmosphere is 1.9 ppm. Air above emission sites such as landfills, anaerobic digestor effluents, rice paddy effluents, and oil and gas wells contains elevated methane in the 500 ppm range. If such sites are targeted for methane removal, technology harnessing aerobic methanotroph metabolism has the potential to become economically and environmentally viable. The first step in developing such methane removal technology is to identify methanotrophs with enhanced ability to grow and consume methane at 500 ppm and lower. We report here that some existing methanotrophic strains grow well at 500 ppm methane, and one of them, Methylotuvimicrobium buryatense 5GB1C, consumes such low methane at enhanced rates compared to previously published values. Analyses of bioreactor-based performance and RNAseq-based transcriptomics suggest that this ability to utilize low methane is based at least in part on extremely low non-growth-associated maintenance energy and on high methane specific affinity. This bacterium is a candidate to develop technology for methane removal at emission sites. If appropriately scaled, such technology has the potential to slow global warming by 2050.

BACKGROUND: Men who have sex with men who ever injected drugs (ever MSM-IDU) carry a high hepatitis C virus (HCV) burden. We estimated whether current HCV testing and treatment in San Francisco can achieve the 2030 World Health Organization (WHO) HCV elimination target on HCV incidence among ever MSM-IDU. METHODS: A dynamic HCV/HIV transmission model among MSM was calibrated to San Francisco data, including HCV antibody (15.5%, 2011) and HIV prevalence (32.8%, 2017) among ever MSM-IDU. MSM had high HCV testing (79%-86% ever tested, 2011-2019) and diagnosed MSM had high HCV treatment (65% ever treated, 2018). Following coronavirus disease 2019 (COVID-19)-related lockdowns, HCV testing and treatment decreased by 59%. RESULTS: Among all MSM, 43% of incident HCV infections in 2022 were IDU-related. Among ever MSM-IDU in 2015, HCV incidence was 1.2/100 person-years (95% credibility interval [CrI], 0.8-1.6). Assuming COVID-19-related declines in HCV testing/treatment persist until 2030, HCV incidence among ever MSM-IDU will decrease by 84.9% (95% CrI, 72.3%-90.8%) over 2015-2030. This decline is largely attributed to HCV testing and treatment (75.8%; 95% CrI, 66.7%-89.5%). Slightly greater decreases in HCV incidence (94%-95%) are projected if COVID-19 disruptions recover by 2025 or 2022. CONCLUSIONS: We estimate that HCV incidence will decline by >80% over 2015-2030 among ever MSM-IDU in San Francisco, achieving the WHO target.

INTRODUCTION: Young transgender women (trans women) experience poor health in part due to discrimination. Factors that promote resilience may help young trans women positively adapt to discrimination, resulting in attenuation of poor health outcomes. While religion is sometimes a source of stigma and transphobia, qualitative studies have identified religiosity as an important resilience resource for young trans women. The goals of this study were to quantitatively measure religiosity and resilience among young trans women and to assess whether they are associated. METHODS: From 2012-2013, 300 young trans women between the ages of 16-24 years were enrolled in a longitudinal study; we examined the cross-sectional baseline data on demographics, religiosity, and resilience. Bivariate and multivariable logistic regression analysis examined the correlation between demographics (age, gender, race/ethnicity, education, income) and religiosity among young trans women. Additionally, bivariate and multivariable logistic regression analysis examined the association between religiosity and resilience among young trans women, controlling for age, gender, race/ethnicity, education, and income. RESULTS: Participants who reported high religiosity had significantly greater odds (aOR 1.78, 95% CI 1.05-3.01, p = .03) of reporting high resilience compared to those reporting low religiosity. Black/African American participants had significantly higher odds (aOR 6.16, 95% CI 2.34-16.20, p = < .001) of reporting high religiosity compared to those who identified as White. CONCLUSION: Religiosity may be an important resilience resource for young trans women. Gender affirming religious and spiritual interventions may promote resilience among some young trans women.

Perinatal mental health (PMH) disorders affect about one in seven women in the peripartum period with significant maternal and neonatal effects. It is important to understand trends in PMH to plan for necessary resource allocation. This study reviews the PMH trends in a major tertiary obstetric centre over 10 years from 2013 to 2022. Over this period there was a significant increase in the rates of anxiety from 7.4 to 18.4% (P < 0.001), depression from 13.6 to 16.3% (P < 0.001) and anxiety and/or depression from 16.5 to 22.6% (P < 0.001). These findings provide further information for resource allocation to improve long-term outcomes.

BACKGROUND AND OBJECTIVE: An important barrier to HIV prevention among transgender women (TGW) is the concern that oral pre-exposure prophylaxis (PrEP) negatively affects the efficacy of feminizing hormone therapy (FHT). We aimed to assess the impact of PrEP on FHT pharmacokinetics (PK) among TGW from Brazil. METHODS: We performed a drug-drug interaction sub-study among TGW enrolled in a daily oral PrEP demonstration study (PrEParadas, NCT03220152). Participants had a first PK assessment (PK1) 15 days after FHT (estradiol valerate 2-6 mg plus spironolactone 100-200 mg) initiation and then started PrEP (tenofovir disoproxil fumarate 300 mg/emtricitabine 200 mg). A second PK evaluation was performed 12 weeks later (PK2). Blood samples were collected prior and after the directly observed dosing (0, 0.5, 1, 2, 4, 6, 8, and 24 hours). Pharmacokinetic parameters of estradiol, spironolactone, and metabolites were estimated by non-compartmental analysis (Monolix 2021R2, Lixoft®) and compared as geometric mean ratios (GMRs, 90% confidence interval [CI]). RESULTS: Among 19 TGW who completed the substudy, median age was 26 years (interquartile range: 23-27.5). Estradiol area under the plasma concentration-time curve (AUCτ) and trough concentrations did not differ between PK1 and PK2 evaluations (GMR [90% CI]: 0.89 [0.76-1.04] and 1.06 [0.94-1.20], respectively). Spironolactone and canrenone AUCτ were statistically lower at PK2 than PK1 (0.76 [0.65-0.89] and 0.85 [0.78-0.94], respectively). Canrenone maximum concentration was also lower at PK2 than PK1 (0.82 [0.74-0.91]). CONCLUSION: Estradiol PK was not influenced by PrEP concomitant use. The small differences observed in some spironolactone and canrenone PK parameters should not prevent the concomitant use of estradiol-based FHT and PrEP. TRIAL REGISTRATION: This trial (NCT03220152) was registered on July 18, 2017.

Purpose: Sex work is a common form of work among young trans women (YTW). Methods: Using an occupational health frame, we measured associations between demographics, sex work, and vocational outcomes in 18-month visit data from the SHINE study (n=263, San Francisco). Results: Overall, 41.8% reported lifetime sex work, primarily escorting/paid sex. Motivations included "better pay" and "can't get a job due to gender discrimination." Occupational injuries included anxiety (53.6%) and depression (50%), with significantly higher relative risk for YTW doing multiple types of sex work. Criminalization experiences (i.e., incarceration, arrests, and police interaction) were common. Conclusion: Results echo calls for sex worker-affirming mental health care for YTW.
RESUMO
BACKGROUND: An enduring challenge remains about how to effectively implement programs, services, or practices. Too often, implementation does not achieve its intended effectiveness, fidelity, and sustainability, even when frameworks or theories determine implementation strategies and actions. A different approach is needed. This scoping review joined two markedly different bodies of literature: implementation and hermeneutics. Implementation is usually depicted as focused, direct, and somewhat linear, while hermeneutics attends to the messiness of everyday experience and human interaction. Both, however, are concerned with practical solutions to real-life problems. The purpose of the scoping review was to summarize existing knowledge on how a hermeneutic approach has informed the process of implementing health programs, services, or practices. METHODS: We completed a scoping review by taking a Gadamerian hermeneutic approach to the JBI scoping review method. Following a pilot search, we searched eight health-related electronic databases using broadly stated terms such as implementation and hermeneutics. A diverse research team that included a patient and healthcare leader, working in pairs, independently screened titles/abstracts and full-text articles. Through the use of inclusion criteria and full-team dialogue, we selected the final articles and identified their characteristics, hermeneutic features, and implementation components. RESULTS: Electronic searches resulted in 2871 unique studies. After full-text screening, we retained six articles that addressed both hermeneutics and implementing a program, service, or practice. The studies varied widely in location, topic, implementation strategies, and hermeneutic approach. All addressed assumptions underpinning implementation, the human dimensions of implementing, power differentials, and knowledge creation during implementation. All studies addressed issues foundational to implementing such as cross-cultural communication and surfacing and addressing tensions during processes of change. The studies showed how creating conceptual knowledge was a precursor to concrete, instrumental knowledge for action and behavioral change. Finally, each study demonstrated how the hermeneutic process of the fusion of horizons created new understandings needed for implementation. CONCLUSIONS: Hermeneutics and implementation have rarely been combined. The studies reveal important features that can contribute to implementation success. Implementers and implementation research may benefit from understanding, articulating, and communicating hermeneutic approaches that foster the relational and contextual foundations necessary for successful implementation.

Stigma towards trans women in Nepal creates individual and system-level risks for HIV. A critical protective factor is access to HIV prevention. Research is needed to determine the impact of stigma on HIV testing among trans women in Nepal. We conducted a secondary analysis of data collected using respondent driven sampling in 2019 on HIV risk among trans women in Nepal. Data analysis was restricted to trans women who were HIV negative at testing through the parent study. Descriptive statistics, tests for bivariable associations between HIV testing and stigma variables, and binomial Poisson regression were conducted to examine HIV testing outcomes. There were 173 participants who tested negative for HIV in our sample. The majority were under age 35 (59%) and most had a grade school education or less (64.7%). No trans women were homeless and most rented a room (70.5%) or owned their home (19.7%). The majority were currently sex workers (57.8%). Almost all HIV-negative trans women had ever been tested for HIV (90.8%), but only 53.5% in the last 3 months. The most frequently cited reason for not having been tested was thinking they were at low risk for HIV (40.9%) and being afraid of receiving a positive test result (22.7%). HIV and anti-trans stigma were high across most measures, including that almost all (94.2%) believed that most people in Nepal would discriminate against people with HIV. And most participants thought trans women were not accepted in Nepali Society (65.9%). Most participants also reported high social support (70.5%). Social cohesion among participants varied, with most experiencing medium (41.6%) or high (33.5%) social cohesion. Just over half had high social participation (55.5%). Participants who reported current sex work had lower prevalence of not testing for HIV in the last 3 months (prevalence ratio, PR = 0.54, 95% confidence interval, 95%CI = 0.32-0.92, p = 0.02). Every one-unit increase in social cohesion was associated with 1.05 times the prevalence of not testing for HIV in the last 3 months (95%CI = 1.01-1.09, p-value = 0.02). Trans women who did sex work were more likely to be HIV tested while those who were more socially connected to peers were less likely to have recently been tested for HIV. HIV stigma may result in fear of social rejection from peers if one tests positive. Interventions that focus on addressing stigma within trans women's social networks and strategies to mitigate HIV stigma in society may result in increased frequency of HIV testing among trans women in Nepal.
