Correlates of concordance between self-reported and lab-confirmed viral load among Black and Latine men who have sex with men (BLMSM) living with HIV in New York City.

Sustained viral suppression is one of the four strategies in the U.S. Department of Health and Human Services' (HHS) plan to end the HIV epidemic in the United States. Individuals living with HIV must understand their viral load accurately for this strategy to be effective. We conducted cross-sectional analyses using baseline data from the NNHIV longitudinal study among men who have sex with men (MSM) living with HIV in New York City to identify factors associated with concordant knowledge between self-reported and lab-confirmed viral load. Of 164 Black and/or Latine participants, 67% (n = 110) reported that their viral load was undetectable, however lab tests showed only 44% (n = 72) had an undetectable viral load (<20 copies/ml). Overall, 62% of the sample (n = 102) had concordant HIV viral load knowledge (agreement of self-reported and lab viral load). In multivariable regression, those with unstable housing (PR = 0.52, 0.30-0.92) and those who had higher levels of beliefs of racism in medicine scale (PR = 0.76, 0.59-0.97) were less likely to have concordant knowledge. Our study underscores the need for implementing measures to improve viral load knowledge, U = U messaging, and strategies to achieve and maintain undetectable viral load status to reduce the burden of HIV at the population level.

Reducing Intersecting Stigmas in HIV Service Organizations: An Implementation Science Model.

BACKGROUND: HIV-related and intersectional stigmas are key barriers for service delivery, but best practices are nascent for addressing them in high-resource and high-burden contexts such as New York City (NYC). The Stigma Reduction and Resilience (STAR) implementation science (IS) Mapping Project in 2020 identified untested stigma reduction efforts in HIV organizations, highlighting the need for an IS framework. SETTING: Organizations providing HIV prevention and/or care in NYC. METHODS: An interagency team determined that IS provides a structured approach for addressing identified gaps in stigma reduction efforts, but defining existing IS concepts and adapting IS frameworks were necessary to facilitate its use. The Implementation Research Logic Model was adapted to empower HIV organizations to use IS to implement stigma reduction. RESULTS: Questions, definitions, and tips were developed to guide, strengthen, and simplify the application of IS within HIV organizations to improve the reduction of HIV and intersecting stigmas. The resulting Stigma Reduction Logic Model incorporates tools for implementers who synthesize each component of the logic model (intervention, determinants, implementation strategies, mechanisms, and outcomes), including a menu of options for selecting stigma reduction interventions and implementation determinants, a checklist to assess organizational readiness for stigma reduction, and an IS terminology guide applied for stigma reduction. CONCLUSIONS: Stigma reduction initiatives and research can use this model to enable implementers, researchers, and HIV organization stakeholders to use the methodology of IS to build consensus for, systematically plan, implement, and evaluate stigma reduction activities relevant to the HIV epidemic. The next step is testing the model's utility.

HIV and Intersectional Stigma Reduction Among Organizations Providing HIV Services in New York City: A Mixed-Methods Implementation Science Project.

Stigma remains a pervasive barrier to Ending the HIV Epidemic (EHE) in New York City (NYC). As part of an EHE implementation science planning process, we mapped multi-level HIV-related stigma-reduction activities, assessed their evidence base, and characterized barriers and facilitators. We interviewed and surveyed a convenience sample of 27 HIV prevention and/or treatment services organizations in NYC, March-August, 2020, using an embedded mixed-methods design. The greatest facilitators of stigma reduction included integration of health services, hiring staff who represent the community, and trainings. Intersecting stigmas were primarily addressed through the integration of HIV with mental health and substance use services. Barriers were multilevel, with organizational structure and capacity most challenging. A strong base of stigma-reduction activities was utilized by organizations, but intersectional frameworks and formal evaluation of activities' impact on stigma were lacking. Effectiveness-implementation hybrid research designs are needed to evaluate and increase the uptake of effective stigma-reduction approaches in NYC.

Locating the Risk: Using Participatory Mapping to Contextualize Perceived HIV Risk across Geography and Social Networks among Men Who Have Sex with Men in the Deep South.

HIV incidence among African American (AA) young men who have sex with men (YMSM) has remained stable even though they made up the largest number of new HIV diagnoses among men who have sex with men (MSM) in 2017. HIV spreads at increased rates in dense sexual networks. Identifying the location of risk behaviors "activity spaces" could inform geographically circumscribed HIV prevention interventions. Utilizing the modified social ecological model we completed five semi-structured focus groups incorporating a modified social mapping technique, based on Singer et al.'s approach. Participants included 27 AA YMSM. Focus groups explored how and where HIV transmission happens in Jackson, Mississippi. Result themes included: 1) location of sexual behaviors, 2) knowledge of geographic hotspots of HIV infection in Jackson, and 3) traveling to meet partners: at home and away. HIV transmission or "activity spaces" may be occurring outside identified HIV hot spots. Mixed geospatial and qualitative methods offered a comprehensive assessment of where HIV transmission occurs, and suggests that geographically circumscribed interventions may need to focus on where individuals living with HIV reside and in specific geographic locations where they engage in behaviors that raise their HIV acquisition risks.

Genomic transformation and social organization during the Copper Age-Bronze Age transition in southern Iberia.

The emerging Bronze Age (BA) of southeastern Iberia saw marked social changes. Late Copper Age (CA) settlements were abandoned in favor of hilltop sites, and collective graves were largely replaced by single or double burials with often distinctive grave goods indirectly reflecting a hierarchical social organization, as exemplified by the BA El Argar group. We explored this transition from a genomic viewpoint by tripling the amount of data available for this period. Concomitant with the rise of El Argar starting ~2200 cal BCE, we observe a complete turnover of Y-chromosome lineages along with the arrival of steppe-related ancestry. This pattern is consistent with a founder effect in male lineages, supported by our finding that males shared more relatives at sites than females. However, simple two-source models do not find support in some El Argar groups, suggesting additional genetic contributions from the Mediterranean that could predate the BA.

Angiotensin-Converting Enzyme Inhibitors and Angiotensin Receptor Blockers Withdrawal Is Associated with Higher Mortality in Hospitalized Patients with COVID-19.

Our main aim was to describe the effect on the severity of ACEI (angiotensin-converting enzyme inhibitor) and ARB (angiotensin II receptor blocker) during COVID-19 hospitalization. A retrospective, observational, multicenter study evaluating hospitalized patients with COVID-19 treated with ACEI/ARB. The primary endpoint was the incidence of the composite outcome of prognosis (IMV (invasive mechanical ventilation), NIMV (non-invasive mechanical ventilation), ICU admission (intensive care unit), and/or all-cause mortality). We evaluated both outcomes in patients whose treatment with ACEI/ARB was continued or withdrawn. Between February and June 2020, 11,205 patients were included, mean age 67 years (SD = 16.3) and 43.1% female; 2162 patients received ACEI/ARB treatment. ACEI/ARB treatment showed lower all-cause mortality (p < 0.0001). Hypertensive patients in the ACEI/ARB group had better results in IMV, ICU admission, and the composite outcome of prognosis (p < 0.0001 for all). No differences were found in the incidence of major adverse cardiovascular events. Patients previously treated with ACEI/ARB continuing treatment during hospitalization had a lower incidence of the composite outcome of prognosis than those whose treatment was withdrawn (RR 0.67, 95%CI 0.63-0.76). ARB was associated with better survival than ACEI (HR 0.77, 95%CI 0.62-0.96). ACEI/ARB treatment during COVID-19 hospitalization was associated with protection on mortality. The benefits were greater in hypertensive, those who continued treatment, and those taking ARB.

Insight on the Genetics of Atrial Fibrillation in Puerto Rican Hispanics.

Non-Hispanic whites present with higher atrial fibrillation (AF) prevalence than other racial minorities living in the mainland USA. In two hospital-based studies, Puerto Rican Hispanics had a lower prevalence of atrial fibrillation of 2.5% than non-Hispanic Whites with 5.7%. This data is particularly controversial because Hispanics possess a higher prevalence of traditional risk factors for developing AF yet have a lower AF prevalence. This phenomenon is known as the atrial fibrillation paradox. Despite recent advancements in understanding AF, its pathogenesis remains unclear. In this study, we compared a genetic dataset of Puerto Rican Hispanics to 111 SNP known to be associated with AF in a large European cohort and determine if they are associated with AF susceptibility in our cohort. To achieve this aim, we performed a secondary analysis of existing data using the following two studies: (1) The Pharmacogenetics of Warfarin in Puerto Ricans study and the (2) A Genomic Approach for Clopidogrel in Caribbean Hispanics, and assess for the presence of European SNPs associated with AF from the genome-wide association study of 1 million people identifies 111 loci for atrial fibrillation. We used data from 555 cardiovascular Puerto Rican Hispanic patients, consisting of 486 control and 69 cases. We found that the following SNPs showed significant association with AF in PHR: rs2834618, rs6462079, rs7508, rs2040862, and rs10458660. Some of these SNPs are proteins involved in lysosomal activities responsible for breaking ceramides to sphingosines and collagen deposition around atrial cardiomyocytes. Furthermore, we performed a machine learning analysis and determined that Native American admixture and heart failure were strongly predictive of AF in PHR. For the first time, this study provides some genetic insight into AF's mechanisms in a Puerto Rican Hispanic cohort.

Who counts as family? Family typologies, family support, and family undermining among young adult gay and bisexual men.

Gay and bisexual men may form chosen families in addition to or in place of families of origin. However, the characteristics of these diverse families remain largely unexamined in the quantitative literature. The purpose of this study was to develop a family typology based on responses from a racially and ethnically diverse sample of young adult gay and bisexual men (YGBM) recruited from the Detroit Metropolitan Area (N=350; 18-29 years old). To explore the role of family, we then examined family social support and social undermining in relation to YGBM psychological distress within different family types. A series of multivariate regressions were used to examine associations between family social support and social undermining with depression and anxiety outcomes. The majority (88%) of YGBM included family of origin in their definitions of family and 63% indicated having chosen families. Associations between family social processes and psychological outcomes varied by type of family, suggesting that family composition shapes how perceptions of support and undermining relate to experiencing symptoms of depression and anxiety. Chosen families play a prominent role in the lives of YGBM and should not be overlooked in family research. Findings also highlight the importance of examining co-occurring family social support and social stress processes to further address psychological distress symptoms among YGBM.

Psychosocial Obstacles to Smoking Cessation Attempts Among Young Adult Sexual Minority Women Who Smoke.

Sexual minority women (SMW; i.e., women who identify their sexuality as lesbian, bisexual, or something other than heterosexual) report greater smoking behaviors than their heterosexual counterparts across all ages. We conducted a multivariable regression to examine the correlates of prior smoking cessation attempts and smoking cessation intentions in a sample of young SMW who smoke (N = 338; aged 18-24 years). Covariates included sociodemographic characteristics (i.e., race/ethnicity, sexual identity, age, urbanity), general (i.e., perceived stress), and sexuality-specific (i.e., internalized homophobia) stressors, as well as smoking attitudes and subjective norms. Bisexual women (OR = 1.92, 95% CI: 1.11, 3.31) were more likely than lesbian counterparts to report a prior smoking cessation attempt. Prior cessation attempts were associated with less internalized homophobia (OR = 0.44, 95% CI: 0.27, 0.69) and positive attitudes toward smoking (OR = 2.17, 95% CI: 1.27, 3.70). Smoking cessation intentions in the next month were negatively associated with being a daily smoker (ß = -0.14) and attitudes toward smoking (ß = -0.19). Based on these findings, we underscore the need to address the risk correlates associated with SMW's quit attempts and include these in cessation interventions.

Cost-Utility Study of Warfarin Genotyping in the VACHS Affiliated Anticoagulation Clinic of Puerto Rico.

OBJECTIVE: To evaluate the cost-utility of the pharmacogenetic-guided dosing of warfarin (PGx), when compared to the current dosing strategy. METHODS: A Markov model was developed to assess the impact of the genotypingguided warfarin dosing in a hypothetical cohort of patients. The model was based on the percentage of time patients spent within the therapeutic international normalized ratio (INR) range (PTTR). PTTR estimates and genotype distribution were derived from a cohort of patients (n = 206) treated in the Veteran Affairs Caribbean Healthcare System (VACHS) and from results of other research study. Costs, utilities and event probability data were obtained from the literature. Probabilistic and one-way sensitivity analyses were performed to explore the range of plausible results. Willingness to pay was established at $50,000 per Quality Adjusted Life Year (QALY) gained. RESULTS: According to our model, the PGx strategy showed a QALY increase of 0.0021, with an increase in total cost of $272. This corresponds to an incremental cost-utility ratio (ICUR) of $127,501, ranging from $95,690 to $148,611. One-way sensitivity analysis revealed that the ICURs were more sensitive to the cost of genotyping and the effect of genotyping on the PTTR. CONCLUSION: Our model suggests that the warfarin PGx was not superior to the standard of care dosing strategy in terms of cost-utility.

Warfarin Anticoagulation Therapy in Caribbean Hispanics of Puerto Rico: A Candidate Gene Association Study.

Existing algorithms account for ~50% of observed variance in warfarin dose requirements after including common polymorphisms. However, they do not perform as well in populations other than Caucasians, in part because some ethno-specific genetic variants are overlooked. The objective of the present study was to identify genetic polymorphisms that can explain variability in warfarin dose requirements among Caribbean Hispanics of Puerto Rico. Next-Generation Sequencing of candidate genes CYP2C9 and VKORC1 and genotyping by DMET® Plus Assay of cardiovascular patients were performed. We also aimed at characterizing the genomic structure and admixture pattern of this study cohort. Our study used the Extreme Discordant Phenotype approach to perform a case-control association analysis. The CYP2C9 variant rs2860905, which was found in all the major haplotypes occurring in the Puerto Rican population, showed stronger association with warfarin sensitivity (<4 mg/day) than common variants CYP2C9*2 and CYP2C9*3. Although, CYP2C9*2 and CYP2C9*3 are separately contained within two of the haplotypes, 10 subjects with the sensitive phenotype were carriers of only the CYP2C9 rs2860905 variant. Other polymorphisms in CES2 and ABCB1 were found to be associated with warfarin resistance. Incorporation of rs2860905 in a regression model (R2 = 0.63, MSE = 0.37) that also includes additional genetics (i.e., VKORC1-1639 G>A; CYP2C9 rs1856908; ABCB1 c.IVS9-44A>G/ rs10276036; CES2 c.269-965A>G/ rs4783745) and non-genetic factors (i.e., hypertension, diabetes and age) showed better prediction of warfarin dose requirements than CYP2C9*2 and CYP2C9*3 combined (partial R2 = 0.132 vs. 0.023 and 0.007, respectively, p < 0.001). The genetic background of Puerto Ricans in the study cohort showed a tri-hybrid admixture pattern, with a slightly higher than expected contribution of Native American ancestry (25%). The genomic diversity of Puerto Ricans is highlighted by the presence of four different major haplotype blocks in the CYP2C9 locus. Although, our findings need further replication, this study contributes to the field by identifying novel genetic variants that increase predictability of stable warfarin dosing among Caribbean Hispanics.

Exploring young adult sexual minority women's perspectives on LGBTQ smoking.

Smoking rates are higher among lesbian, gay, bisexual, transgender, and queer (LGBTQ) individuals than among heterosexuals. These disparities are exacerbated during the transition from youth to young adulthood. The current study uses in-depth qualitative interviews to understand perceptions of LGBTQ smoking among LBQ-identified women (N=30, ages 18-24). Major themes identified include the belief that smoking was a way of overcoming stressors faced by heterosexual and LGBTQ young adults alike, a mechanism to relieve sexuality-related stressors, and an ingrained part of LGBTQ culture. Results suggest unique stressors influence LGBTQ smokers. Implications for smoking cessation interventions for LGBTQ youth are discussed.

[Changes in clinic-epidemiological characteristics of new cases of HIV-1 infection in Castellón (Spain), and its impact on delayed presentation (1987-2011)]. / Cambios en las características clínico-epidemiológicas de los nuevos casos de infección por el VIH-1 en Castellón (España) y su repercusión en la presentación tardía (1987-2011).

OBJECTIVE: To describe the trend of the clinical and epidemiological characteristics of a cohort of HIV-1 infected patients in Castellón (Spain), and its impact on the delayed presentation. METHODS: Data from HIV-1 infected outpatients presenting for care for the first time between 1987 and 2011 were retrospectively analyzed. RESULTS: There have been significant changes in the characteristics of the 1001 newly presented patients during the period studied. An increase in the mean age was observed (increasing from about 30 years before 1996, to approximately 35 after the 2000-2002 period), as well as an increase in the percentage of immigrants (<2% before 1997, to 50% in the 2009-2011 period), and a decline in the proportion of intravenous drug use as the main transmission route (changing from being 92.3% before 1988 to below 20% after the 2003-2005 period), together with a decrease in the proportion of hepatitis-C coinfection. The rate of late presentation has not significantly changed, being 47.1% in the period studied. Factors associated with this late presentation were: older age, hospital diagnosis, an increased delay between estimated infection time and diagnosis, and between diagnosis and initial presentation. CONCLUSIONS: The epidemiology of HIV-1 infection in our area has dramatically changed since the beginning of the disease. The increasing delay between estimated infection time and diagnosis is an important cause of the lack of variation in the late presentation rate, and highlights the low impact of early diagnosis strategies.

LGBT community, social network characteristics, and smoking behaviors in young sexual minority women.

Smoking rates among young sexual minority women (YSMW) are disproportionately high as compared to heterosexual populations. While this disparity has commonly been attributed to the sexual minority stress process, little empirical work has explored what may protect YSMW from high rates of smoking. Using data (N = 471) from a cross-sectional study designed to investigate YSMW's (age 18-24) smoking behaviors and correlates; we explore the relationship of LGBT community connections, YSMW's social network characteristics, and stress to smoking behaviors (i.e., status, frequency, amount). Through this analysis, we find support for LGBT community connection as well as friendships with other sexual minorities as protective in relation to YSMW's smoking behaviors. We discuss the implications of our results, highlighting the need for future longitudinal research and interventions designed to bolster YSMW's connections to the LGBT community and their social networks.

PrEP awareness and perceived barriers among single young men who have sex with men.

Pre-exposure prophylaxis (PrEP) has the potential to help reduce new HIV infections among young men who have sex with men (YMSM). Using a cross-sectional survey of YMSM (N=1,507; ages 18-24), we gauged YMSM's PrEP awareness and PrEP-related beliefs regarding side effects, accessibility, and affordability. Overall, 27% of the sample had heard about PrEP; 1% reported ever using PrEP prior to sex. In a multivariate logistic regression, we found that YMSM were more likely to have heard about PrEP if they were older, more educated, were residentially unstable in the prior 30 days, had insurance, or reported having at least one sexually transmitted infection in their lifetime. We found no differences by race/ethnicity, history of incarceration, or recent sexual risk behavior. In multivariate linear regression models, Black and Latino YMSM were more likely than Whites to state they would not use PrEP because of side effect concerns. YMSM were more likely to indicate that they would not be able to afford PrEP if they did not have insurance or if they had a prior sexually transmitted infection, PrEP rollout may be hindered due to lack of awareness, as well as perceived barriers regarding its use. We propose strategies to maximize equity in PrEP awareness and access if it is to be scaled up among YMSM.

Optimising expanded donor organs through dual kidney transplantation: a case-control study.

INTRODUCTION: In order to take full advantage of ECD kidneys, which may not provide sufficient renal mass if used individually, it has been suggested that such organs be used in dual or bilateral kidney transplantation (DTx). PATIENTS AND METHOD: We analysed the experience in a single hospital between May 2007 and March 2011 in a case-control study. Criteria for determining whether to perform single or dual Tx were defined in a protocol in which the biopsy score was important, but not the only factor. Donor's age, medical history, kidney size and creatinine clearance were also considered. During this time period, 80 kidneys from donors over age 65 were transplanted. Single transplants (STx) accounted for 40 of the organs, and another 40 were used in DTx. RESULTS: Mean donor age for STx was 68.7 ± 3.0 years; for DTx, it was 74.2 ± 4.3 years (P<.001), with more female donors for DTx (75%) than for STx (40%) (P<.001). There were no differences between groups with regard to glomerular filtration rate or proteinuria. Kidneys assigned to DTx received higher biopsy scores than those assigned to STx (2.95 ± 1.01 vs 1.8 ± 1.04; P<.001). DTx recipients were older than STx recipients. There were no differences between the groups regarding cold ischaemia time, delayed graft function, haemorrhagic complications or re-surgeries. However, DTx recipients achieved better creatinine clearance at 1, 3, 6 and 12 months, although the difference was only statistically significant at 6 months (53.4 ± 19.5ml/min vs 44.5 ± 15.6ml/min; P<.05). Renal artery thrombosis appeared in 2 STx patients and in both kidneys of 1 DTx patient. Another 2 patients in the DTx group each lost 1 kidney due to thrombosis and ureteral necrosis respectively, but were able to remain dialysis-free. Graft survival at 3 years was 90% for both groups. During the study period 3 patients died (2 in the STx group and 1 in the DTx group). CONCLUSIONS: Our preliminary experience indicates that DTx provides good results in terms of survival and renal function data, despite surgery being more complicated and the organs having characteristics that probably make them unsuitable for STx. The decision to perform DTx makes using ECD kidneys easier, and it should be based on a combination of pre-transplant histological criteria and the donor's clinical characteristics.
