LAI-ART Awareness, Willingness, Barriers and Facilitators among Black Sexual Minority Men Living with HIV in the US South.

Black sexual minority men (BSMM) continue to bear a disproportionate burden of HIV in the United States, with the highest incidence and prevalence in the southern region of the country. In Texas, BSMM living with HIV (BSMM+) have the lowest rates of viral suppression of all SMM and have lower antiretroviral treatment (ART) adherence than white and Hispanic SMM. Long-acting injectable ART (LAI-ART) can potentially overcome several barriers to daily oral ART adherence (e.g., stigma, forgetfulness, pill fatigue). However, little is known about the knowledge, willingness, barriers, and facilitators regarding LAI-ART among BSMM+. From July 2022 to September 2023, we conducted in-depth, semi-structured interviews with 27 BSMM+ from the Houston and Dallas Metropolitan Areas, Texas. Data were analyzed using a thematic analysis approach. Most men knew about LAI-ART, but their understanding varied based on their existing sources of information. Some men were enthusiastic, some were cautious, and some reported no interest in LAI-ART. Barriers to LAI-ART included a lack of public insurance coverage of LAI-ART; fear of needles and side effects; the frequency of injection visits; the requirement of viral suppression before switching from oral ART to LAI-ART; and satisfaction with oral daily ART. Motivators of LAI-ART uptake included the eliminated burden of daily pills and reduced anxiety about possibly missing doses. BSMM+ may be among those who could most benefit from LAI-ART, though more research is needed to understand which factors influence their willingness and how the barriers to LAI-ART might be addressed, particularly among diverse communities of SMM of color.

Is Sacubitril/Valsartan a Superior Agent in Heart Failure With Reduced Ejection Fraction? A Review of Randomized Comparative Trials.

Background: The PARADIGM HF trial showed sacubitril/valsartan (SV) to be superior to enalapril in patients with reduced ejection fraction (HFrEF). Since its publication, several other randomized trials have compared SV to either an angiotensin converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB) in HFrEF which showed conflicting results regarding mortality, hospitalizations, and quality of life scoring. Objective: To review randomized comparative trials of SV to either ACEI or ARB in patients with HFrEF. Methods: PubMed and Embase databases were used to identify randomized comparative trials. The text terms sacubitril, angiotensin neprilysin, and LCZ696 were used for both searches. Meta-analysis, retrospective, adhoc, and cohort studies were excluded. Results: 1476 and 3983 citations were reviewed on PubMed and Embase, respectively. Of these, 11 randomized comparative trials to either ACEI or ARB were included for analysis. The mortality/quality of life benefits of SV over enalapril in the PARADIGM HF were not corroborated in any of the other trials. The effect of hospitalizations for heart failure was inconsistent among trials. Exercise tolerance was not improved with SV versus enalapril. Conclusion: The results of the PARADIGM HF trial have largely not been confirmed in subsequent randomized comparative trials.

Sacubitril/valsartan compared to equivalent/sub-equivalent dose angiotensin receptor blocker or angiotensin-converting enzyme inhibitor in heart failure with reduced ejection fraction: a meta-analysis of randomized trials.

PURPOSE: The objective of this meta-analysis is to determine how sacubitril/valsartan (SV) compares to equivalent and sub-equivalent angiotensin receptor blockers (ARB) or angiotensin-converting enzyme inhibitors (ACEI) in patients with heart failure with reduced ejection fraction (HFrEF). METHODS: The databases of PubMed and EMBASE were used to identify those randomized controlled trials which compared SV to ARB/ACEI in patients with HFrEF. Only those trials that reported outcomes regarding total mortality, cardiovascular mortality, and worsening heart failure were considered. Meta-analysis was performed separately in those patients receiving equivalent doses of ARB/ACEI and those receiving sub-equivalent doses. Equivalent doses were SV 97/103 = valsartan 160 mg twice daily = enalapril 20 mg twice daily = ramipril 5 mg twice daily. Meta-analyses were performed using Review Manager 5.4. RESULTS: Twelve randomized trials were identified involving 17,484 patients: 11,291 in the sub-equivalent group (8 trials) and 6193 in the equivalent group (4 trials). Meta-analyses showed there were no statistical differences regarding the outcomes of total mortality, cardiovascular mortality, and worsening heart failure in the equivalent dosing group. However, SV reduced total mortality (risk ratio (RR) = 0.85, 95% confidence interval (CI) = 0.78-0.93, p < 0.001), cardiovascular mortality (RR = 0.81, 95% CI = 0.73-0.90, p ≤ 0.001) and worsening heart failure (RR = 0.77, 95% CI = 0.64-0.92, p = 0.005) in the sub-equivalent group. CONCLUSION: When compared to equivalent doses of ARB/ACEI, SV is not superior in reducing mortality and worsening heart failure. SV is superior when compared to sub-equivalent doses of ACEI.

A Co-Created Tool to Help Counter Health Misinformation for Spanish-Speaking Communities in the San Francisco Bay Area.

BACKGROUND: Health misinformation, which was particularly prevalent during the COVID-19 pandemic, hampers public health initiatives. Spanish-speaking communities in the San Francisco Bay Area may be especially affected due to low digital health literacy and skepticism towards science and healthcare experts. Our study aims to develop a checklist to counter misinformation, grounded in community insights. METHODS: We adopted a multistage approach to understanding barriers to COVID-19 vaccine uptake in Spanish-speaking populations in Alameda and San Francisco counties. Initial work included key informant and community interviews. Partnering with a community-based organization (CBO), we organized co-design workshops in July 2022 to develop a practical tool for identifying misinformation. Template analysis identified key themes for actionable steps, such as source evaluation and content assessment. From this, we developed a Spanish-language checklist. FINDINGS: During formative interviews, misinformation was identified as a major obstacle to vaccine uptake. Three co-design workshops with 15 Spanish-speaking women resulted in a 10-step checklist for tackling health misinformation. Participants highlighted the need for scrutinizing sources and assessing messenger credibility, and cues in visual content that could instill fear. The checklist offers a pragmatic approach to source verification and information assessment, supplemented by resources from local CBOs. CONCLUSION: We have co-created a targeted checklist for Spanish-speaking communities to identify and counter health misinformation. Such specialized tools are essential for populations that are more susceptible to misinformation, enabling them to differentiate between credible and non-credible information.

Differential Associations of Depressive Symptomology to HIV Care Engagement Among Young Black Sexual Minority Men with HIV (YBSMM+) in the US South: A Multi-Group Analysis of Mood, Intimate Partner Violence, and Alcohol Use.

Young Black Sexual Minority Men with HIV (YBSMM+) in the US South encounter multiple socio-structural challenges that contribute to disproportionately poor HIV-related outcomes across the care continuum. Depression, anxiety, intimate partner violence (IPV), and alcohol use are prominent factors that negatively impact engagement with HIV care. Syndemic theory posits that these multiple factors interact synergistically to promote poor outcomes; however, depression itself is highly heterogeneous in presentation, which may pose issues when examining associations to HIV care engagement. This study sought to better understand the associations of specific depressive symptomology subtypes, generalized anxiety, experienced IPV, and alcohol use on HIV care engagement for YBSMM+. Results showed that interpersonally oriented depressive symptomatology was associated with increased HIV care engagement among YBSMM + who abstained from alcohol. On the other hand, among YBSMM + who frequently binge drank, combined negative affect and somatic components of depressive symptomatology and frequency of IPV experiences were associated with decreased HIV care engagement while generalized anxiety was associated with increased HIV care engagement. The findings suggest that the negative affect and somatic components of depression may be particularly salient for HIV care engagement among YBSMM + who binge drink frequently. Developing targeted interventions that address these specific conditions while accounting for the nuances of mood-based symptomatology could improve intervention efforts geared towards improving HIV care engagement among YBSMM+.

What's in Your Dataset? Measuring Engagement in HIV Care Using Routinely Administered Items with a Population Disproportionately Burdened by HIV.

We evaluated the psychometric properties of a measure consisting of items that assess current HIV care continuum engagement based on established definitions in the United States. At baseline, participants in this longitudinal study, which included three time points from 2015 to 2020, were 331 young Black sexual minority men ages 18-29 living with HIV in the southern United States residing in two large southern cities. Self-report items reflected four aspects of HIV care continuum engagement as binary variables: seeing a healthcare provider for HIV care, being on antiretroviral treatment, being retained in HIV care, and being virally suppressed. Of these, the following three variables loaded onto a single factor in exploratory factor analysis: being on antiretroviral treatment, being retained in HIV care, and being virally suppressed. A one-dimensional factor structure was confirmed using confirmatory factor analyses at separate time points. Additionally, the three items collectively showed measurement invariance by age, education level, employment status, and income level. The three-item measure also showed reliability based on coefficient omega and convergent validity in its associations with indicators of socioeconomic distress, depression, resilience, and healthcare empowerment. In sum, the items performed well as a single scale. The study demonstrated the potential psychometric strength of simple, feasible, commonly administered items assessing engagement in the HIV care continuum.

Structural Inequities, Syndemics, and Resilience: The Critical Role of Social Support in Overcoming Barriers and Empowering Engagement in HIV Care for Young Black Sexual-Minority Men in the US South.

Young Black sexual minority men (YBSMM) living in the US South are among those most disproportionately impacted by HIV in the USA. This health inequity is, in part, due to lower rates of sustained engagement in the HIV care continuum, resulting in a lower prevalence of viral suppression and higher overall community-level viral load. Social, structural, and economic inequities have previously been linked with poorer HIV care engagement among YBSMM. HIV-related social support, individual-level resilience, and healthcare empowerment have been shown to be independently associated with improved HIV care engagement. The current study sought to assess the relative contribution of individual, structural, and economic factors on engagement in HIV care and to elucidate the potentially mediating role of healthcare empowerment. Data from 224 YBSMM with HIV in the US South indicated that greater levels of socioeconomic distress, intimate partner violence, and depressive symptoms were associated with lower levels of engagement in HIV care, while greater levels of individual-level resilience and healthcare empowerment were associated with higher levels of HIV care engagement. Importantly, healthcare empowerment mediated the association between resilience and engagement in HIV care and the association between social support and engagement in HIV care. Findings emphasize the critical role that HIV-related social support plays in fostering resilience and overcoming syndemic factors to promote empowerment and engagement in HIV care for YBSMM in the USA.

Attribution of individual methane and carbon dioxide emission sources using EMIT observations from space.

Carbon dioxide and methane emissions are the two primary anthropogenic climate-forcing agents and an important source of uncertainty in the global carbon budget. Uncertainties are further magnified when emissions occur at fine spatial scales (<1 km), making attribution challenging. We present the first observations from NASA's Earth Surface Mineral Dust Source Investigation (EMIT) imaging spectrometer showing quantification and attribution of fine-scale methane (0.3 to 73 tonnes CH4 hour-1) and carbon dioxide sources (1571 to 3511 tonnes CO2 hour-1) spanning the oil and gas, waste, and energy sectors. For selected countries observed during the first 30 days of EMIT operations, methane emissions varied at a regional scale, with the largest total emissions observed for Turkmenistan (731 ± 148 tonnes CH4 hour-1). These results highlight the contributions of current and planned point source imagers in closing global carbon budgets.

Supporting and Uplifting New and Diverse Scientists in HIV Research (San Diego SUN): A Research Education and Training Program to Promote the Success of Black, Indigenous, and People of Color Predoctoral and Postdoctoral Fellows.

BACKGROUND: We implemented a mentored research education and training program for underrepresented minorities (URMs) and Black, Indigenous, and People of Color (BIPOC) predoctoral and postdoctoral fellows called San Diego SUN (SD SUN): Supporting and Uplifting New and Diverse Scientists in HIV Research. The SD SUN program aimed to prepare fellows for an academic career trajectory in HIV science focused on ameliorating HIV-related disparities in communities of color. SETTING: The program leveraged a strong interinstitutional collaboration between San Diego State University and the University of California, San Diego, that share commitments to diversity, equity, and inclusion and an established history of training programs for URM/BIPOC investigators. METHODS: During a 9-month training period, launched in February 2022, fellows supported by a mentoring team completed ten 3-hour training sessions (core curriculum) and a mentored research project. The curriculum included seminars on building skills for a productive academic research career and reflective discussions around issues uniquely faced by URM/BIPOC investigators. Standardized measures developed for Center for AIDS Research Diversity, Equity, and Inclusion Pipeline Initiative (eg, around benefits gained) were used to evaluate the program. RESULTS: Six fellows participated in the SD SUN program. The results demonstrated a successful first year. Fellows were highly engaged and reported positive experiences, satisfaction with their mentor(s), various benefits gained from the program, and gains in numerous skillsets. CONCLUSIONS: Challenges were faced during implementation (eg, teaching grant writing to fellows at different skill levels). Time constraints were reported by some faculty mentors with limited bandwidth. We describe insights and solutions to the major challenges to sustaining the successful SD SUN program.

Medical mistrust of health systems as a moderator of resilience and self-reported HIV care engagement in Black and Latinx young adults living with HIV.

OBJECTIVE: To study resilience and its association with HIV care engagement in a sample of young adult Black and Latinx people living with HIV (PLWH) in the United States and to test if a systems-level barrier, medical mistrust, would moderate the resilience-engagement association. METHOD: Between April and August 2021, we recruited participants through social media and dating apps (N = 212) and verified age and HIV status through a review process of digital text-messaged and emailed photos. Participants completed a one-time online survey consisting of the Connor-Davidson Resilience Scale, The Index of Engagement in HIV Care, and the Medical Mistrust Index. We ran a regression-based moderation analysis using the Johnson-Neyman Technique to estimate regions of significance. RESULTS: The sample (N = 212) was 80.5% Black and 19.5% Latinx with a mean age of 25.8 years (SD = 2.84). Higher resilience scores were associated with higher HIV care engagement scores (b = 0.72, p = .003), and medical mistrust moderated this relationship as evidenced by a mistrust by resilience interaction (b = -0.16, p = .01). Our regions of statistical significance showed that as mistrust increased, the size of the resilience-engagement association decreased. CONCLUSION: Resilience may be a protective factor associated with greater participation and sense of connection to HIV care, but is diminished by mistrust of the medical system at large. This suggest that systems-level changes, in addition to individual-level interventions, are needed to address medical mistrust to fully harness the resilience of young PLWH.

Radiosensitivity and early onset cancer.

The article is concerned with the radioprotection of a substantial radiosensitive population who present with cancer in early adulthood and will probably be treated with radiotherapy. A theory of radiation-induced health effects based on the induction of DNA double strand breaks is used to associate the radio-sensitivity of carriers of the BRCA1 and BRCA2 genes and the PALB2 gene with the defects in the homologous recombination repair of DNA damage found in the carriers. It is concluded that the defects in homologous recombination repair in these carriers will lead to an increased level of somatic mutations in all their cells and that this increased level of somatic mutations throughout their lifetime is, essentially, the reason that the carriers develop early onset cancer. This is a direct consequence of the more rapid accumulation of the cancer-inducing somatic mutations than the normal, slower accumulation in non-carriers. The radiotherapeutic treatment of these carriers needs to proceed with some care, taking account of their increased radio-sensitivity, and this suggests a need for international recognition and guidance of their radioprotection within the medical profession.

Climate lags and genetics determine phenology in quaking aspen (Populus tremuloides).

Spatiotemporal patterns of phenology may be affected by mosaics of environmental and genetic variation. Environmental drivers may have temporally lagged impacts, but patterns and mechanisms remain poorly known. We combine multiple genomic, remotely sensed, and physically modeled datasets to determine the spatiotemporal patterns and drivers of canopy phenology in quaking aspen, a widespread clonal dioecious tree species with diploid and triploid cytotypes. We show that over 391 km2 of southwestern Colorado: greenup date, greendown date, and growing season length vary by weeks and differ across sexes, cytotypes, and genotypes; phenology has high phenotypic plasticity and heritabilities of 31-61% (interquartile range); and snowmelt date, soil moisture, and air temperature predict phenology, at temporal lags of up to 3 yr. Our study shows that lagged environmental effects are needed to explain phenological variation and that the effect of cytotype on phenology is obscured by its correlation with topography. Phenological patterns are consistent with responses to multiyear accumulation of carbon deficit or hydraulic damage.

Brief Report: The Influence of the COVID-19 Pandemic on the Physical, Social, and Mental Health of Black and Latinx Young People With HIV in the United States.

BACKGROUND: Whereas national attention has been paid to the ongoing mental health crises among young people triggered by the COVID-19 pandemic, less is known about the social, physical and psychological impacts of COVID-19 on young people living with HIV, especially racial/ethnic minorities. SETTING: Online survey of participants across the U.S. METHOD: A national cross-sectional survey of non-Latinx Black and Latinx young adults (18-29) living with HIV. Between April and August 2021, participants answered survey questions about several domains (eg, stress, anxiety, relationships, work, quality of life) that were worsened, improved, or unchanged during the pandemic. We ran a logistic regression estimating the self-reported impact of the pandemic on these domains between 2 age groups (ages 18-24 versus 25-29). RESULTS: The sample size was 231 (186 non-Latinx Black, 45 Latinx) and mainly male (84.4%) and gay identified (62.2%). Nearly 20% of participants were 18-24 years old and 80% were ages 25-29. Participants who were 18-24 years old reported 2-3 times the odds for having worse sleep quality and mood and greater stress, anxiety, and weight gain compared with those 25-29 years old. CONCLUSION: Our data provide a nuanced picture of the negative impacts that COVID-19 had on non-Latinx Black and Latinx young adults living with HIV in the U.S. Given that these adults represent a priority population for HIV treatment outcomes, it is critical to better understand the ongoing toll that these dual pandemics have on their lives.

"I Was Always Trying to Figure It Out on My Own Terms": Structural Barriers, the Internet, and Sexual Identity Development among Lesbian, Gay, Bisexual, and Queer People of Different Generations.

Recognizing the historical grounding of sexual identity development, we examined the spontaneous narration of the internet's significance among a diverse sample of three distinct birth cohorts of sexual minority adults (n = 36, ages 18-59) in the United States. Thematic analysis revealed two structural barriers and four roles of the internet in sexual identity development. Structural barriers were being in a heterosexual marriage (exclusive to members of the older cohort), and (2) growing up in a conservative family, religion, or community (which cut across cohorts). Roles of the internet included: learning about LGBQ+ identities and sex; watching pornography (which appeared only in narratives of the younger cohort); finding affirming community; and facilitating initial LGBQ+ romantic and sexual experiences (which appeared mostly in narratives of the younger cohort). Most participants who described the internet as playing a role in sexual identity development were members of the younger (ages 18-25) and middle (ages 34-41) cohorts. We discuss how the internet has assumed a unique role in history in the development of sexual minority people. Further, our findings highlight that sexual identity development occurs across the lifespan, and how that process and the roles of the internet vary by generation and structural realities.

Willingness of Racially Diverse Young Adults Living with HIV to Participate in HIV Cure Research: A Cross-Sectional Survey in the United States.

Nearly half of new HIV cases in the United States are among youth. Little is known about the willingness of young adults living with HIV (YLWH) to participate in HIV cure-related research. In 2021, we recruited 271 YLWH aged 18-29 for an online survey. We asked questions about willingness to participate in HIV cure research, perceived risks and benefits, acceptable trade-offs, and perceptions on analytical treatment interruptions. We conducted descriptive analyses to summarize data and bivariate analyses to explore correlations by demographics. Most respondents (mean age = 26) identified as men (86%) and Black Americans (69%). YLWH expressed high willingness to consider participating in cell- and gene-based approaches (75%) and immune-based approaches (71%). Approximately 45% would be willing to let their viral load become detectable for a period of time during an HIV cure study, 27% would not be willing, and 28% did not know. The social risk most likely to deter participation was the possibility of transmitting HIV to sex partners while off HIV medications (65% of respondents would be deterred a great deal or a lot). Compared to the 25-29 age group (n = 192), the 18-24 age group (n = 79) was more likely to indicate that having to disclose HIV status would matter a great deal in considering participation in HIV cure research (38% vs. 21%, p = .003). Inclusion and engagement of YLWH are critical for advancing novel HIV curative agents. Our article concludes with possible considerations for engaging YLWH in HIV cure research. Physical, clinical, and social risks will need to be kept to a minimum, and research teams will need to proactively mitigate the possibility of transmitting HIV to sex partners while off HIV medications.

The Ongoing Process of HIV-Stigma (Re)Production.

HIV stigma negatively affects the social experiences of people living with HIV (PLWH) and remains a challenge to HIV prevention, treatment, and care. Research has overwhelmingly focused on individual cognitive measures of HIV stigma (e.g., internalized, anticipated, and experienced). However, little research explores the interactions and societal structures through which HIV stigma is produced. Data from qualitative interviews with 30 black gay and bisexual men living with HIV in the U.S. Deep South revealed an interconnected and interdependent set of processes that produce and reproduce HIV stigma. These included social interactions (silence, euphemism, and gossip), witnessed acts of marginalization, word-of-mouth transmission of HIV misinformation, and laws and policies carried out within the education and criminal justice systems. Efforts to reduce stigma that focus on individual beliefs and attitudes are critical to improving the well-being of PLWH. However, reducing HIV stigma requires intervening on the social interactions and structures through which HIV stigma is produced and reproduced.

Overcoming Challenges of Online Research: Measures to Ensure Enrollment of Eligible Participants.

BACKGROUND: Internet-based surveys are increasingly used for health research because they offer several advantages including greater geographic reach, increased participant anonymity, and reduced financial/time burden. However, there is also a need to address inherent challenges, such as the likelihood of fraudulent responses and greater difficulty in determining eligibility. METHODS: We conducted an online nationwide survey of 18-29 year olds living with HIV in the United States, to assess willingness to participate in HIV cure research. To ensure that respondents met age and HIV serostatus inclusion criteria, we instituted screening procedures to identify ineligible respondents using tools that were built into the survey platform (eg, reCAPTCHA, geolocation) and required documentation of age and serostatus before providing access to the incentivized study survey. RESULTS: Of 1308 eligibility surveys, 569 were incomplete or ineligible because of reported age or serostatus. Of the remaining 739 potentially eligible respondents, we determined that 413 were from fraudulent, bot, or ineligible respondents. We sent individual study survey links to 326 participants (25% of all eligibility survey respondents) whose eligibility was reviewed and confirmed by our study team. CONCLUSION: Our multicomponent strategy was effective for identifying ineligible and fraudulent responses to our eligibility survey, allowing us to send the study survey link only to those whose eligibility we were able to confirm. Our findings suggest that proactive fraud prevention can be built into the screening phase of the study to prevent wasted resources related to data cleaning and unretrievable study incentives and ultimately improve the quality of data.

Exploration of a Mobile Technology Vulnerability Scale's association with antiretroviral adherence among young adults living with HIV in the United States.

Background: Young adults living with HIV (YLWH) have suboptimal adherence to antiretroviral therapy (ART) and HIV care outcomes. Mobile health technologies are increasingly used to deliver interventions to address HIV health outcomes. However, not all YLWH have equal and consistent access to mobile technologies. Methods: Using our novel Mobile Technology Vulnerability Scale (MTVS) to evaluate how vulnerable an individual feels with regard to their personal access to mobile technology in the past 6 months, we conducted a cross-sectional online survey with 271 YLWH (18-29 years) in the US to evaluate the relationships between MTVS and self-reported ART adherence. Results: Participants reported changes in phone numbers (25%), stolen (14%) or lost (22%) phones, and disconnections of phone service due to non-payment (39%) in the past 6 months. On a scale of 0 to 1 (0 having no mobile technology vulnerability and 1 having complete mobile technology vulnerability), participants had a mean MTVS of 0.33 (SD =0.26). Black and financially constrained participants had the highest MTVS, which was significantly higher that other racial/ethnic and financially non-constrained groups, respectively. Higher MTVS was significantly associated with ART non-adherence and non-persistence. Conclusions: Findings suggest the need to measure MTVS to recognize pitfalls when using mobile health interventions and identify populations whose inconsistent mobile technology access may be related to worse health outcomes.
