RESUMO

PROBLEM: Bacterial vaginosis (BV) disproportionally impacts Black and Hispanic women, placing them at risk for HIV, sexually transmitted infections and preterm birth. It is unknown whether there are differences by genetic ancestry in BV risk or whether polymorphisms associated with BV risk differ by ancestry. METHODS: Women's Interagency HIV Study (WIHS) participants with longitudinal Nugent scores were dichotomized as having (n = 319, Nugent 7-10) or not having BV (n = 367, Nugent 0-3). Genetic ancestry was defined by clustering of principal components from ancestry informative markers and further stratified by BV status. 627 single nucleotide polymorphisms (SNPs) across 41 genes important in mucosal defense were identified in the WIHS GWAS. A logistic regression analysis was adjusted for nongenetic predictors of BV and self-reported race/ethnicity to assess associations between genetic ancestry and genotype. RESULTS: Self-reported race and genetic ancestry were associated with BV risk after adjustment for behavioral factors. Polymorphisms in mucosal defense genes including syndecans, cytokines and toll-like receptors (TLRs) were associated with BV in all ancestral groups. CONCLUSIONS: The common association of syndecan, cytokine and TLR genes and the importance of immune function and inflammatory pathways in BV, suggests these should be targeted for further research on BV pathogenesis and therapeutics.

RESUMO

Despite the prevalence of HIV among transgender women (TGW), gaps exist in understanding the impact of HIV-related stigma (HRS) on TGW with HIV. This is a small cross-sectional pilot study examining HRS in TGW (n=18) with HIV in Miami, FL, who completed a survey during an HIV clinical visit. In contrast with previous studies, results demonstrated low levels of HRS and suggest the potential of increasing acceptance of TGW with HIV as a contributing factor. Larger studies are needed to explore factors underlying HRS with the aim of further reducing stigma among TGW with HIV.

RESUMO

Long-acting injectable antiretroviral therapy (LAI ART) has the potential to address adherence obstacles associated with daily oral ART, leading to enhanced treatment uptake, adherence, and viral suppression among people living with HIV (PLWH). Yet, its potential may be limited due to ongoing disparities in availability and accessibility. We need a better understanding of the organizational context surrounding the implementation of LAI ART, and to inform its widespread rollout, we conducted 38 in-depth interviews with medical and social service providers who offer HIV care at private and hospital-based clinics across six US cities. Our findings highlight real-world implementation barriers outside of clinical trial settings. Providers described ongoing and anticipated barriers across three stages of LAI ART implementation: (1) Patient enrollment (challenges registering patients and limited insurance coverage), (2) medication delivery (insufficient personnel and resources), and (3) leadership and management (lack of interprofessional coordination and a lack of programming guidelines). Providers described how these barriers would have a disproportionate impact on under-resourced clinics, potentially exacerbating existing disparities in LAI ART access and adherence. Our findings suggest strategies that clinic leadership, policymakers, and other stakeholders can pursue to promote rapid and equitable LAI ART implementation in clinics across the United States. Resource and staffing investments could support clinics to begin, sustain, and scale up LAI ART delivery; additionally, the establishment of guidelines and tools could facilitate wider adoption of LAI ART across clinical settings. These efforts are crucial to promote resourced, standardized, and equitable implementation of LAI ART and maximize its potential to help end the HIV epidemic.

RESUMO

INTRODUCTION: This study used an unsupervised machine learning algorithm, sidClustering and random forests, to identify clusters of risk behaviors of Bacterial Vaginosis (BV), the most common cause of abnormal vaginal discharge linked to STI and HIV acquisition.  METHODS: Participants were 391 cisgender women in Miami, Florida, with a mean of 30.8 (SD = 7.81) years of age; 41.7% identified as Hispanic; 41.7% as Black and 44.8% as White. Participants completed measures of demographics, risk behaviors [sexual, medical, and reproductive history, substance use, and intravaginal practices (IVP)], and underwent collection of vaginal samples; 135 behavioral variables were analyzed. BV was diagnosed using Nugent criteria. RESULTS: We identified four clusters, and variables were ranked by importance in distinguishing clusters: Cluster 1: nulliparous women who engaged in IVPs to clean themselves and please sexual partners, and used substances frequently [n = 118 (30.2%)]; Cluster 2: primiparous women who engaged in IVPs using vaginal douches to clean themselves (n = 112 (28.6%)]; Cluster 3: primiparous women who did not use IVPs or substances [n = 87 (22.3%)]; and Cluster 4: nulliparous women who did not use IVPs but used substances [n = 74 (18.9%)]. Clusters were related to BV (p < 0.001). Cluster 2, the cluster of women who used vaginal douches as IVPs, had the highest prevalence of BV (52.7%). CONCLUSIONS: Machine learning methods may be particularly useful in identifying specific clusters of high-risk behaviors, in developing interventions intended to reduce BV and IVP, and ultimately in reducing the risk of HIV infection among women.

RESUMO

Gender affirmation may reduce stigma and gender-based discrimination that drive increased behaviors that can lead to HIV in transgender women (TW). For many TW, vaginoplasty is gender affirming, yet has not been previously evaluated with regard to likelihood of HIV. This pilot study of TW aimed to evaluate the influence of gender-affirming vaginoplasty on stigma and the drivers of HIV acquisition. Adult TW without HIV were recruited. Interviewer-administered surveys were used to assess demographics, gender identity stigma, psychosocial factors, importance of and satisfaction with gender affirmation, and behaviors that increase the likelihood of HIV in TW who had either undergone gender-affirming vaginoplasty (TWWV) or who had not (TWWOV). Statistical analysis was conducted using descriptive statistics, Fisher's exact tests, and Wilcoxon rank-sum tests. Thirty TW without HIV (19-83 years old) participated (TWWV = 10; TWWOV = 20). The majority identified with ethnic minority groups (n = 21, 70%) and on gender-affirming hormone therapy (n = 25, 83%). Gender identity stigma (38.0; 32.15, p = .03) and social oppression (53.6; 39.4, p = .05) scores were significantly higher among TWWV compared with TWWOV. Satisfaction with body (3.10; 1.95, p = .01), appearance (3.10; 2.10, p = .02), and femininity (3.40; 2.25, p = .001) were higher among TWWV than TWWOV. Present (n = 8, 27%) and past (n = 16, 53%) survival sex work, multiple sex partners (n = 16, 53%), and receptive condomless anal intercourse (n = 10, 33%) were reported but did not vary significantly between groups. Behaviors that may lead to HIV acquisition and their underlying drivers, including gender identity stigma, are present after gender-affirming vaginoplasty. As this procedure continues to increase among TW, interventions to mitigate chances of HIV acquisition are critically needed in this population.

RESUMO

BACKGROUND: The HIV/AIDS epidemic has disproportionately affected Black individuals in the USA, and this health disparity has increased over time. Despite the effectiveness of pre-exposure prophylaxis (PrEP) as a prevention tool for HIV, there are disparities in its use, and uptake of this intervention remains low among racial and ethnic minorities, including Haitians/Haitian Americans. In this study, factors influencing PrEP use among Haitians/Haitian Americans in Miami, FL, are explored to provide necessary data to address disparities. METHODS: The research team collaborated with local organizations to recruit 30 individuals (Haitians/Haitian Americans) between February 4 and October 1, 2021, and conducted semi-structured interviews. All interviews were audio-recorded and transcribed, and NVivo® was used to analyze the transcripts for emergent themes. RESULTS: The study sample comprised 30 adults of Haitian descent in Miami, FL (50% female, approximately 67% with a high school education or more, mean age = 43.7 ± 13 years, and 74.2% born in Haiti). Four primary themes emerged from the analysis: (1) limited PrEP awareness, (2) underutilization of PrEP, (3) inadequate discussion of HIV prevention strategies, and (4) PrEP delivery encompassing barriers and facilitators for PrEP delivery and promotion strategies. CONCLUSION: This study indicated that there is a critical need to increase Haitians/Haitian Americans' knowledge regarding PrEP. Health communication interventions tailored specifically for Haitians/Haitian Americans that target stigma, attitudes toward HIV, and risk perception may be significant in increasing PrEP in this population.

RESUMO

Zika virus (ZIKV) is a flavivirus primarily transmitted by Aedes species mosquitoes, first discovered in Africa in 1947, that disseminated through Southeast Asia and the Pacific Islands in the 2000s. The first ZIKV infections in the Americas were identified in 2014, and infections exploded through populations in Brazil and other countries in 2015/16. ZIKV infection during pregnancy can cause severe brain and eye defects in offspring, and infection in adults has been associated with higher risks of Guillain-Barré syndrome. We initiated a study to describe the natural history of Zika (the disease) and the immune response to infection, for which some results have been reported. In this paper, we identify ZIKV-specific CD4+ and CD8+ T cell epitopes that induce responses during infection. Two screening approaches were utilized: an untargeted approach with overlapping peptide arrays spanning the entire viral genome, and a targeted approach utilizing peptides predicted to bind human MHC molecules. Immunoinformatic tools were used to identify conserved MHC class I supertype binders and promiscuous class II binding peptide clusters predicted to bind 9 common class II alleles. T cell responses were evaluated in overnight IFN-γ ELISPOT assays. We found that MHC supertype binding predictions outperformed the bulk overlapping peptide approach. Diverse CD4+ T cell responses were observed in most ZIKV-infected participants, while responses to CD8+ T cell epitopes were more limited. Most individuals developed a robust T cell response against epitopes restricted to a single MHC class I supertype and only a single or few CD8+ T cell epitopes overall, suggesting a strong immunodominance phenomenon. Noteworthy is that many epitopes were commonly immunodominant across persons expressing the same class I supertype. Nearly all of the identified epitopes are unique to ZIKV and are not present in Dengue viruses. Collectively, we identified 31 immunogenic peptides restricted by the 6 major class I supertypes and 27 promiscuous class II epitopes. These sequences are highly relevant for design of T cell-targeted ZIKV vaccines and monitoring T cell responses to Zika virus infection and vaccination.

RESUMO

Voluntary Medical Male Circumcision (VMMC) is an effective strategy for HIV prevention in areas with high prevalence of, and risk for, HIV. More than 361,000 male neonates are born each year in Zambia, many of whom could be eligible for Early-Infant Medical Circumcision (EIMC). Building on successful implementation strategies utilized in our Spear & Shield program, this pilot study, "Like Father, Like Son" (LFLS), evaluated the feasibility and acceptability of offering combined EIMC and VMMC services and couple-level behavioral interventions. A total of N = 702 pregnant women and their male partners (n = 351 couples) were recruited and enrolled. Couples were assessed twice pre-birth, 2 weeks post birth, and 6 months post birth. Expectant mothers were an average of 15.05 weeks pregnant (SD = 8.83). Thirty-nine pregnancies did not result in a live birth (11%), 14 couples withdrew from the study or were lost to follow-up prior to delivery (4%), and 148 babies were born female (42%), leaving 150 couples with a male infant in the analytic sample (43%). The LFLS study achieved significantly higher EIMC rates (35%) in comparison with previously observed EIMC study rates in Zambia (11%), and significantly higher than hypothetical comparison rates up to 30%. Relative to baseline rates, odds of VMMC among couples' older sons increased by 31% at post-intervention and by 90% at two-weeks following birth. Overall, this pilot study found the LFLS intervention to be feasible, acceptable, and effective in doubling the rate of EIMC in comparison with a previous longitudinal study in Zambia. Future research should consider a family-centric approach to promotion of male circumcision for infants and adolescents. LFLS may be effective in promoting father-son "bonding" by MC status; a bond that may be a bridge to increase both EIMC and VMMC uptake in newborns and couples' older sons and is a novel leverage point for promotion of this HIV prevention strategy.

RESUMO

Dysmenorrhea (menstrual pain) is common among adolescent girls globally, but many girls in Sub-Saharan Africa do not receive effective treatment. Qualitative interviews were used to describe adolescent girls' experiences of dysmenorrhea and identify sociocultural barriers to dysmenorrhea management in Moshi, Tanzania. From August to November 2018, in-depth interviews were conducted with 10 adolescent girls and 10 adult experts (e.g., teachers, medical providers) who have experience working with girls in Tanzania. Thematic content analysis identified themes related to dysmenorrhea, including descriptions of dysmenorrhea and the impact of dysmenorrhea on well-being, as well as factors influencing the use of pharmacological and behavioral pain management strategies. Potential barriers to dysmenorrhea management were identified. Dysmenorrhea negatively impacted the physical and psychological well-being of girls and hindered girls' ability to participate in school, work, and social events. The most common pain management strategies were resting, drinking hot water, engaging in physical activity, and taking paracetamol. Barriers to dysmenorrhea management included beliefs that medications are harmful to the body or can hinder fertility, limited knowledge about the benefits of hormonal contraceptives to manage menstruation, little continuing education for healthcare providers, and a lack of consistent access to effective medications, medical care, or other supplies necessary for pain management. Medication hesitancy and inconsistent access to effective medication and other menstrual supplies must be addressed to improve girls' ability to manage dysmenorrhea in Tanzania.

RESUMO

Purpose: Transgender women (TW) are disproportionately affected by HIV infection and cardiovascular disease (CVD). This study evaluated whether estrogen-based gender-affirming hormone therapy (GAHT) in TW with HIV (TWH-GAHT) is associated with indices of subclinical CVD. Methods: Of the 40 HIV-seropositive persons enrolled, 20-60 years of age, on antiretroviral treatment with undetectable viral load, assessments were performed on 15 TWH; of these persons, 11 were GAHT treated. These TWH-GAHT were matched with HIV+ cisgender men and women based on age, ethnicity/race, body mass index, and antihypertensive medication use. Sex hormones, and cardiometabolic (waist circumference, blood pressure, insulin resistance, lipid profile, and C-reactive protein), vascular (flow-mediated dilation [FMD] and arterial stiffness), and proinflammatory measures were obtained. Results: TWH-GAHT displayed elevated estradiol and suppressed testosterone levels relative to normative ranges. Analyses indicated the TWH-GAHT displayed lower low-density lipoprotein compared with cisgender groups (p < 0.05). Although no difference was seen on FMD, the central augmentation index of aortic stiffness was higher in cisgender HIV+ women than cisgender HIV+ men (p < 0.05). No other group difference on subclinical CVD markers was observed. For TWH, partial correlations indicated associations of certain sex hormones with selected cardiometabolic outcomes and the inflammatory cytokine, interleukin-8. Conclusion: When well matched to HIV+ cisgender men and women, subclinical CVD pathophysiology did not appear elevated in TWH-GAHT, although tendencies emerged suggesting that some subclinical CVD indices may be higher, but others lower than cisgender groups. Longitudinal studies of TWH are needed to more precisely evaluate the moderating effect of GAHT on cardiometabolic pathophysiology.

RESUMO

BACKGROUND: Miami, Florida is an epicenter of the HIV epidemic in the US, with 20% of new HIV infections occurring in women. Despite effectiveness of Pre-Exposure Prophylaxis (PrEP) in preventing HIV, only 10% of eligible women benefit from its use. SETTING: This study evaluates PrEP awareness and use, and factors associated with PrEP awareness among sexually active women in Miami, Florida. METHODS: Results reported in this study included cross-sectional data that were collected as part of a baseline visit from a parent study. Cis-gender, HIV-negative, 18-45-year-old, sexually active women were recruited as part of a study evaluating recurrent bacterial vaginosis and HIV risk. Participants completed questionnaires assessing socio-demographics, HIV risk factors, prior history of HIV testing and reproductive tract infections, PrEP awareness and use. Relationships between variables and PrEP awareness were analyzed and multivariable logistic regression identified variables strongly associated with PrEP awareness. RESULTS: Among the 295 women enrolled, median age was 31 (24-38) years, 49% Black, 39% White, and 34% Hispanic. Of 63% who knew about PrEP, only 5% were on PrEP. Women with income below poverty line (OR = 2.00[1.04,3.87];p = 0.04), more male sexual partners in past month (OR = 1.30[1.01,1.68];p = 0.04), lifetime HIV testing (OR = 6.42[2.83,14.52];p<0.01), and current bacterial vaginosis (OR = 2.28[1.18,4.40];p = 0.01) were more likely to be aware of PrEP. Lower odds of PrEP awareness were associated with being Black (OR = 0.38[0.15,0.96];p = 0.04), Hispanic (OR = 0.18[0.08,0.39];p<0.01), heterosexual (OR = 0.29[0.11,0.77];p<0.01), and reporting inconsistent condom use during vaginal sex (OR = 0.21[0.08,0.56];p<0.01). CONCLUSION: PrEP awareness is low among reproductive age women in a high-risk setting. Culturally tailored interventions are needed to increase PrEP awareness and uptake, especially among Black and Hispanic women with inconsistent condom use during vaginal sex with male partners.

RESUMO

This study addresses rural Guatemala's poor maternal health and HIV status by culturally adapting an evidence-based HIV intervention, SEPA (Self-Care, Education, Prevention, Self-Care), to extend the capacity of comadronas (Mayan birth attendants) as HIV prevention providers. This mixed-method study examined the acceptability, suitability, and feasibility of SEPA presented to traditional elder and a younger cohort of comadronas over three sessions. Outcome variables were reported as mean scores. Open-ended qualitative responses were categorized under central themes. Session 1, 2, and 3 acceptability (4.6/5, 4.6/5, 4.8/5), suitability (4.7/5, 4.6/5, 4.9/5), and feasibility (4.4/5, 4.7/5, 4.8/5) remained high across sessions. While comadronas reported that information was difficult, they reported high levels of understanding and comfort with SEPA content and they also found it to be culturally appropriate, increasing their confidence to discuss HIV with their community. The broader utilization of comadronas could create a pathway to enhance reproductive health among indigenous women.

RESUMO

OBJECTIVE: Compared to non-Black women, Black women in the United States are more likely to be diagnosed with HIV, living with HIV, and have suboptimal HIV outcomes, disparities largely linked to structural and psychosocial factors that may impact mental health. METHOD: 151 Black women living with HIV (BWLWH) enrolled in a longitudinal cohort study completed baseline assessments between October 2019 and January 2020 in the Southeastern United States. Measures captured microaggressions (gendered-racial, HIV, and Lesbian/Gay/Bisexual/Transgender/Queer), "macro" discrimination acts (gender, race, HIV, sexual orientation), resilience factors (self-efficacy, trait resilience, posttraumatic growth, positive religious coping, and social support), and mental health (depressive symptoms, posttraumatic stress disorder (PTSD) symptoms, and posttraumatic cognitions). Four structural equation models were estimated with latent discrimination (LD), latent microaggression (LM), and latent resilience (LR) as predictors and depressive symptoms, PTSD symptoms, posttraumatic cognitions, and latent mental health (LH) as outcomes. Indirect pathways from LD and LM via LR and LR as a moderator were estimated. RESULTS: Models fit well based on indices. There were significant direct pathways from LM and LR to depressive symptoms, posttraumatic cognitions, and LH and a significant direct pathway from LM to PTSD symptoms, but not from LD to any mental health outcome. Indirect pathways were not significant. However, LR moderated the relationships between both LM and LD with PTSD symptoms. CONCLUSION: Intersectional microaggressions and resilience factors may play key roles in BWLWH's mental health. Research is needed to examine these pathways overtime and provide opportunities to improve mental health and HIV outcomes among BWLWH. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

RESUMO

BACKGROUND: Direct-acting antiviral (DAA) therapy for hepatitis C virus (HCV) is well tolerated, cost-effective, and yields high sustained virologic response rates, yet it has remained financially inaccessible to many patients. METHODS: Participants of the Women's Interagency HIV Study (an observational US cohort) with human immunodeficiency virus (HIV) and HCV (RNA+) reporting no prior hepatitis C treatment were followed for DAA initiation (2015-2019). We estimated risk ratios (RRs) of the relationship between time-varying health insurance status and DAA initiation, adjusting for confounders with stabilized inverse probability weights. We also estimated weighted cumulative incidences of DAA initiation by health insurance status. RESULTS: A total of 139 women (74% Black) were included; at baseline, the median age was 55 years and 86% were insured. Most had annual household incomes ≤$18 000 (85%); advanced liver fibrosis (21%), alcohol use (45%), and recreational drug use (35%) were common. Across 439 subsequent semiannual visits, 88 women (63%) reported DAA initiation. Compared with no health insurance, health insurance increased the likelihood of reporting DAA initiation at a given visit (RR, 4.94; 95% confidence limit [CL], 1.92 to 12.8). At 2 years, the weighted cumulative incidence of DAA initiation was higher among the insured (51.2%; 95% CL, 43.3% to 60.6%) than the uninsured (3.5%; 95% CL, 0.8% to 14.6%). CONCLUSIONS: Accounting for clinical, behavioral, and sociodemographic factors over time, health insurance had a substantial positive effect on DAA initiation. Interventions to increase insurance coverage should be prioritized to increase HCV curative therapy uptake for persons with HIV.

RESUMO

OBJECTIVE: This study describes adverse events following immunization (AEFIs) and the development of SARS-COV-2 antibodies after Sputnik V, AstraZeneca, and Sinopharm COVID-19 vaccination in people with HIV (PWH). METHODS: In total, 595 adult PWH at an HIV center in Argentina from March to December 2021 were enrolled. Analysis included participants who received COVID-19 vaccination with Sputnik V, AstraZeneca, and Sinopharm, and did not receive mRNA COVID-19 vaccines. Clinical data, and local or systemic AEFI variables were collected using an online questionnaire after the first dose. Detection of S1-RBD IgG antibodies was performed between days 28 and 60 after the second dose in a subsample (SARS-CoV-2 IgG chemiluminescent immunoassay; Siemens). A multivariable logistic regression and spearman test were used for analyses. RESULTS: Mean age was 46.1 years (SD = 11.8); 70.4% were men; and median CD4 + T cells count was 659 (500-852) cells/µl. AEFIs were reported in 214 (36.0%) participants. More participants reported AEFIs after Sputnik V (29.4%) and AstraZeneca (47.5%) than Sinopharm (13.9%) (χ 2  = 35.85, P  < 0.001). Higher odds of reporting an AEFIs were associated with receiving Sputnik V [aOR = 2.90; 95% confidence interval (95% CI) = 1.40-6.04; P  = 0.004] and AstraZeneca (aOR = 5.38; 95% CI = 2.63-11.01; P  < 0.001) compared with Sinopharm. Lower odds were associated with age (aOR = 0.97; 95% CI = 0.95-0.99; P  < 0.001). Overall, 76 (95.0%) individuals assessed for the presence of SARS-CoV-2 antibody reached S1-RBD IgG antibody titers at least 1 U/ml; mean titer was 51.3 (SD = 51.07) U/ml. Higher antibody titers correlated with higher CD4 + T cells count (Rho = 0.280; P  = 0.012). CONCLUSION: NonmRNA vaccines showed a good safety profile and adequate SARS-CoV-2 antibody responses among PWH suggesting adequate protection to SARS-CoV-2.

RESUMO

Intravaginal practices (IVPs) refer to placing items (e.g., water, soap, commercial douches, fingers, rags) inside the vagina. IVPs have been shown to contribute to the development of bacterial vaginosis (BV) and may increase sexually transmitted infections and HIV risk. We developed the Intravaginal Practices Questionnaire (IVQ). The purpose of this study was to validate the IVQ, with the goal of establishing a consistent method of assessing IVP across studies. Women enrolled in this study (n = 180) were on average 30 years of age (SD = 8.32). Half (54%) identified as non-Hispanic, and 45% identified as Black; 41% reported lifetime IVP. Past month IVP use included commercial douches (9%), water (35%), fingers (41%), soap (21%), cloths/rags/wipes (10%), and vinegar (3%), which were placed in the vagina. No women used yogurt or herbs. An exploratory factor analysis indicated that a single-factor structure best explained the underlying constructs in participant responses in six endorsed items assessing commercial douches, water, fingers, soap, clothes/rags/ wipes, and vinegar use, suggesting that a common factor underlies these behaviors. All factor loadings were > 0.496. Cronbach's α was 0.99, suggesting that the reliability of the scale was excellent. Lastly, a total IVQ score was related to BV diagnosis (p = .007) as well as self-reported symptoms of BV (p = .034). Results illustrate that the IVQ has adequate psychometric properties. This tool may be used by public health experts and clinicians to identify IVPs that may potentially increase HIV risk.

RESUMO

BACKGROUND: Estrogen-based hormone therapy (HT) may have beneficial cardiovascular effects when initiated in early menopause. This has not been examined in women with human immunodeficiency virus (HIV), who have heightened immune activation and cardiovascular risks. METHODS: Among 609 postmenopausal women (1234 person-visits) in the Women's Interagency HIV Study, we examined the relationship of ever HT use (oral, patch, or vaginal) with subclinical atherosclerosis: carotid artery intima-media thickness (CIMT), distensibility, and plaque assessed via repeated B-mode ultrasound imaging (2004-2013). We also examined associations of HT with cross-sectional biomarkers of immune activation and D-dimer. Statistical models were adjusted for sociodemographic, behavioral, and cardiometabolic factors. RESULTS: Women (mean age, 51 years; 80% HIV positive) who ever used HT at baseline were older, and more likely to be non-Hispanic White and report higher income, than never-users. Women who ever used HT had 43% lower prevalence of plaque (prevalence ratio, 0.57 [95% confidence interval {CI}, .40-.80]; P < .01), 2.51 µm less progression of CIMT per year (95% CI, -4.60, to -.41; P = .02), and marginally lower incidence of plaque over approximately 7 years (risk ratio, 0.38 [95% CI, .14-1.03; P = .06), compared with never-users, adjusting for covariates; ever HT use was not associated with distensibility. These findings were similar for women with and without HIV. Ever HT use was associated with lower serum D-dimer, but not with biomarkers of immune activation after covariate adjustment. CONCLUSIONS: HT may confer a subclinical cardiovascular benefit in women with HIV. These results begin to fill a knowledge gap in menopausal care for women with HIV, in whom uptake of HT is very low.

RESUMO

BACKGROUND: Biological and psychological mechanisms may be responsible for menstrual irregularities occurring among women during the COVID-19 pandemic. STUDY DESIGN: From January 2019 to September 2021, women (18- to 45-years-old and not using hormonal contraception) were recruited in Miami-Dade County, Florida. Cross-sectional, self-report surveys collected data on menstrual irregularities, COVID-19 vaccination, stress, depression, and loneliness. A EUA approved rapid test assay using whole blood measured SARS-CoV-2 IgG antibodies. Chi-square and Fisher's exact tests described menstrual irregularities among women recruited before versus after the start of the COVID-19 pandemic and with detectable versus undetectable SARS-CoV-2 IgG antibodies. A logistic regression examined the relationship between the presence of SARS-CoV-2 IgG antibodies and menstrual irregularities controlling for age, stress, depression, and loneliness. RESULTS: Among 182 women enrolled, 73 were enrolled after pandemic onset, and 36 provided vaccination data. Having detectable SARS-CoV-2 IgG antibodies was associated with a higher percentage of menstrual irregularities among unvaccinated women (0% vs. 39%, p = .026) and among all women regardless of vaccination status (31% vs. 5%; p = .005). Adjusting for age and psychological variables, the odds of menstrual irregularities were 7.03 times (95% CI [1.39, 35.60]; p = .019) higher among women with detectable antibodies compared to women without detectable antibodies. Neither enrollment date, age, nor psychological factors were associated to menstrual irregularities. CONCLUSIONS: Biological mechanisms related to SARS-CoV-2 infection may be responsible for irregular menstruation and should be further examined to mitigate the impact of the COVID-19 pandemic on women's health.
