Incidence of Sexually Transmitted Infections in Youth with HIV During Pre-COVID and COVID Era.

Adolescents and young adults (AYAs) living with HIV have high rates of co-sexually transmitted infections (STIs). During the coronavirus disease (COVID) pandemic, STI prevention strategies, including access to testing/treatment facilities, availability of health care workers, and condom availability, may have decreased. This study aimed to determine if differences in STI incidence for first infection and reinfection existed between the pre-COVID and COVID eras in a cohort of AYAs living with HIV in Atlanta, GA. Retrospective chart review was conducted for all patients between ages 13 and 24 at the Grady Ponce Clinic. Two eras were identified: a pre-COVID era (January 1, 2009-December31, 2019) and a COVID era (January 1, 2020-June 30, 2021). STIs recorded included gonorrhea, chlamydia, human papillomavirus, syphilis, trichomonas, herpes simplex virus, lymphogranuloma venereum, hepatitis C, bacterial vaginosis, and chancroid. First and recurrent incidence rates for any STIs were reported. Our sample included 766 sexually active AYAs with HIV. A total of 721 patients were included in the pre-COVID era and 583 (80.9%) had at least one STI. A total of 337 patients were included in the COVID era, and 158 had at least one STI (46.9%). The overall first STI incidence rate increased from 42.47 to 58.67 per 100 person-years (PY) and the recurrent STI incidence rate increased from 121.50 to 169.85 per 100 PY from the pre-COVID to the COVID era (p < 0.001). Our study demonstrated significantly higher incidence rates of first and recurrent STIs in AYAs living with HIV in the COVID era. We urge continuation of existing STI prevention programs to avoid secondary clinical and economic adverse effects of increased infections.

Labeled dataset for training despeckling filters for SAR imagery.

When training Artificial Intelligence and Deep Learning models, especially by using Supervised Learning techniques, a labeled dataset is required to have an input with data and its corresponding labeled output data. In the case of images, for classification, segmentation, or other processing tasks, a pair of images is required in the same sense, one image as an input (the noisy image) and the desired (the denoised image) one as an output. For SAR despeckling applications, the common approach is to have a set of optical images that then are corrupted with synthetic noise, since there is no ground truth available. The corrupted image is considered the input and the optical one is the noiseless one (ground truth). In this paper, we provide a dataset based on actual SAR images. The ground truth was obtained from SAR images of Sentinel 1 of the same region in different instants of time and then they were processed and merged into one single image that serves as the output of the dataset. Every SAR image (noisy and ground truth) was split into 1600 images of 512 × 512 pixels, so a total of 3200 images were obtained. The dataset was also split into 3000 for training and 200 for validation, all of them available in four labeled folders.

Comparación de protocolos de vacunación contra el virus del papiloma humano en Ecuador y América Latina / Comparation of vaccination protocols against the human papillomavirus in Ecuador and Latin America

INTRODUCCIÓN: El virus del papiloma humano (VPH), con más de 100 tipos, es de transmisión sexual. Varios países de América Latina han introducido las vacunas contra el VPH. Aunque América Latina es la región que más rápido avanzó en la vacunación contra el VPH, sus sistemas de seguimiento y vigilancia son aún deficientes. OBJETIVO: Comparar las diferentes estrategias de vacunación contra el VPH en Ecuador y América Latina. MÉTODO: Revisión bibliográfica, en la que se obtuvo información de documentos gubernamentales y artículos indexados en los últimos 5 años sobre las estrategias de vacunación contra el VPH en Ecuador y América Latina. RESULTADOS: La mayoría de los países de América Latina han logrado introducir la vacuna contra el VPH, excepto Venezuela, Martinica, Haití, Nicaragua y Cuba. CONCLUSIONES: Los protocolos de vacunación de Ecuador y América Latina necesitan mejorar sus sistemas de seguimiento y aumentar la expansión de datos de cobertura disponibles de manera consistente. Actualmente siguen existiendo desafíos para introducir las vacunas, lograr una alta cobertura y fortalecer el seguimiento, la evaluación y la notificación.

INTRODUCTION: The human papilloma virus (HPV), with more than 100 types, is a sexual transmission infection. Many Latin American countries have introduced the vaccines against the HPV. Although Latin América is the region which advanced faster against the HPV, its surveillance and follow-up systems are yet deficient. OBJECTIVE: To compare the different strategies to assume the vaccination against the HPV in Ecuador and Latin America. METHOD: Bibliographic review, in which information was obtained from government documents and articles indexed in the last five years on vaccination strategies against HPV in Ecuador and Latin America. RESULTS: Most Latin American countries have managed to introduce the vaccine against the HPV, except Venezuela, Martinica, Haiti, Nicaragua and Cuba. CONCLUSIONS: The vaccination protocols of Ecuador and Latin América need to improve their systems of follow-up and monitoring, and increase the expansion of available data in a consistent manner. Now, there are still existing challenges to introduce the vaccines, manage a high reach and fortify the follow-up, the evaluation, and the notification.

Factors Associated With Anal High-Grade Intraepithelial Lesions and Carcinoma Among Young Men Who Have Sex With Men and Transgender Women With HIV in Atlanta.

OBJECTIVE: This study aimed to evaluate factors associated with anal high-grade intraepithelial lesions (HSIL) and anal carcinoma among young men who have sex with men (MSM) and transgender women (TW) with HIV in Atlanta, GA, to better inform screening guidelines and preventative measures. MATERIALS AND METHODS: Cross-sectional retrospective chart review was completed for cisgender MSM and TW with HIV aged 13-25 years at the Grady Ponce and Family Youth Clinic in Atlanta, GA, from 2009 to 2020. High-grade anal disease was defined as anal intraepithelial neoplasia (AIN) 2, 3, or anal carcinoma (AIN 2+). Associations between clinical and demographic factors with AIN 2+ were estimated using logistic regression. Adjusted odds ratios (aORs) and associated 90% CIs are reported. RESULTS: One hundred nine MSM and TW with HIV who underwent anoscopy were included. One hundred three participants received anal biopsies, and 62% had AIN 2+. Being incompletely or unvaccinated against human papillomavirus (HPV, 0-2 doses) relative to being fully vaccinated (3 doses; aOR = 5.85; 90% CI = 1.28-26.83; p = .06) and having ever received surgical treatment for anogenital HPV (aOR = 2.89; 90% CI = 1.10-7.65; p = .07) were associated with AIN 2+, controlling for age and CD4 T-cell count at time of biopsy. CONCLUSIONS: Our study found a high prevalence of anal HSIL among young MSM and TW with HIV. Those who had ever received surgical treatment for anogenital HPV and those who were incompletely or unvaccinated against HPV were more likely to have HSIL. Our data emphasize the urgent need to improve HPV vaccination efforts and to pursue larger surveillance studies of anal HSIL and carcinoma among young MSM and TW with HIV.

HIV in Neonates and Infants.

Advances in perinatal HIV management have averted a significant number of infections in neonates and have made the possibility of elimination of mother-to-child transmission a reality; however, significant gaps in implementation of early testing programs as well as the expansion of therapeutic strategies to neonates are hindering prevention efforts and access to safer, more effective and easier to administer treatment. This article provides insights on the current state of perinatal HIV, recent advances, and future needs.

Examining healthcare transition experiences among youth living with HIV in Atlanta, Georgia, USA: a longitudinal qualitative study.

INTRODUCTION: Virtually all youth living with HIV in paediatric/adolescent care must eventually transition to adult-oriented HIV care settings. To date, there is limited evidence examining the perspectives of youth living with HIV longitudinally through the healthcare transition process. The objective of our study was to examine attitudes and experiences of youth living with HIV regarding healthcare transition, including potential change in attitudes and experiences over time. METHODS: We conducted a longitudinal qualitative interview study within a large, comprehensive HIV care centre in Atlanta, Georgia, USA between August 2016 and October 2019.We interviewed 28 youth living with HIV as part of a longitudinal observational cohort study of youth undergoing healthcare transition. We conducted qualitative interviews both immediately prior to, and one year following the transition from paediatric to adult-oriented care. RESULTS: Six distinct themes emerged from interviews conducted with youth living with HIV pre-transition: (1) reluctance to transition; (2) paediatric spaces as welcoming, and adult spaces as unwelcoming; (3) varying levels of preparation for transition; and (4) expectation of autonomy in the adult clinic. Analysis of post-transition interviews with the same youth demonstrated: (1) inconsistencies in the transition experience; (2) fear and anxiety about transition quelled by experience; (3) varying reactions to newfound autonomy and (4) communication as the most valuable facilitator of successful transition. CONCLUSIONS: This study's longitudinal perspective on the healthcare transition experience yields insights that can be incorporated into programming targeting this critically important population. Although our study was conducted in a USA-based clinic with co-located paediatric and adult care services, many of our findings are likely to have relevance in other settings as well. Interventions aiming to improve HIV care engagement through transition should seek to enhance patient-provider communication in both paediatric and adult clinics, improve preparation of patients in paediatric clinics and ease patients gradually into autonomous disease management.

Hallazgo de diclofenaco en un producto fitoterapéutico a base de caléndula comercializado en Colombia / Finding diclofenac in a marigold-based phytotherapeutic product marketed in Colombia

Resumen Introducción: la consulta de un particular que trajo un producto fitoterapéutico a base de caléndula cuyo consumo le causó fuertes reacciones adversas, originó esta investigación sobre la composición de este producto. Objetivo: caracterizar la composición química de muestras de lotes diferentes de un producto comercial denominado fitoterapéutico a base de caléndula (Calendula officinalis) (PFC) comercializado en Colombia. Metodología: se analizaron tabletas de ocho cajas del PFC de cuatro lotes diferentes de producción (2017 y 2018). Se llevó a cabo el análisis de espacio de cabeza (HS) de tabletas por microextracción en fase sólida (SPME), con una fibra PDMS/DVB (65 µm), expuesta al HS de la muestra durante 30 min a 50 °C. Las fracciones volátiles se analizaron por cromatografía de gases acoplada a espectrometría de masas (GC/MS). Los extractos de tabletas obtenidos con mezcla de metanol:agua (1:1, v/v) se analizaron por cromatografía líquida (LC) de alta (HPLC) y ultra-alta eficiencia (UHPLC), con detectores de arreglo de diodos (DAD) y espectrometría de masas de alta resolución (HRMS), respectivamente; la cuantificación de diclofenaco se hizo por calibración con patrón externo y por adición de estándar. Los espectros de masas de baja y alta resolución y patrones de fragmentación de las sustancias detectadas se estudiaron, usando GC/HRMS y LC/HRMS-Orbitrap. Resultados: en tabletas analizadas por HSSPME, se encontraron monoterpenoides y sesquiterpenoides de origen vegetal, ftalatos, residuos de solventes (2-cloroetanol, etilenglicol) y sustancias químicas intermediarias en la síntesis de diclofenaco (2,6-dicloroanilina y 2,6-cloro-N-fenil-bencenamina). En los cromatogramas, obtenidos por GC/MS de los extractos de tabletas obtenidos con diclorometano, se detectaron diclofenaco, sus impurezas A, B y C, los ésteres de diclofenaco y algunas otras impurezas. Diclofenaco en cantidad ca. 40 mg (7-8%) se cuantificó por HPLC en tabletas (> 70 analizadas) escogidas al azar de ocho cajas del PFC, adquirido en el mercado local de Bucaramanga (Colombia). Conclusión: en cada tableta analizada se determinaron alrededor de 40 mg del compuesto sintético diclofenaco (sustancia no declarada en la etiqueta del producto) y en ninguna se detectaron ésteres de los triterpenoides oleanano o faradiol, constituyentes del extracto de caléndula que poseen actividad antiinflamatoria; se encontraron algunos flavonoides comunes a muchas plantas, en cantidades mil veces menores que la de diclofenaco.

Abstract Introduction: The consultation of a person who brought a marigold-based phytotherapeutic product whose consumption caused strong adverse reactions, originated this investigation of the composition of this product. Objective: to characterize the chemical composition of samples of different lots of a commercial product called calendula-based phytotherapeutic product (Calendula officinalis) (PFC) commercialized in Colombia. Methodology: Tablets of eight packs of the phytotherapeutic product from four different production batches (2017 and 2018) were analyzed. Headspace analysis (HS) of tablets by solid phase microextraction (SPME) was carried out with a PDMS/ DVB fiber (65 µm), exposed to the HS of the sample for 30 min at 50 °C. Volatile fractions were analyzed by gas chromatography coupled to mass spectrometry (GC/MS). Tablet extracts obtained with methanol:water mixture (1:1, v / v) were analyzed by liquid chromatography (LC) of high (HPLC) and ultra-high performance (UHPLC) with diode array (DAD) and high-resolution mass spectrometric (HRMS) detectors, respectively; diclofenac was quantified by external calibration and standard addition. Low- and high-resolution mass spectra (MS, HRMS) and fragmentation patterns of detected substances were studied, using GC/HRTOF-MS and LC/HRMS-Orbitrap. Results: in tablets analyzed by HS-SPME, monoterpenoids and sesquiterpenoids of plant origin, phthalates, solvent residues (2-chloroethanol, ethylene glycol) and intermediary chemicals in diclofenac synthesis (2,6-dichloroaniline and 2,6- chloro-N-phenyl-benzenamine) were found. In the chromatograms (GC/MS) of the extracts of tablets obtained with organic solvent (dichloromethane), diclofenac, its impurities A, B and C, diclofenac esters, and some other compounds were detected; diclofenac quantification by HPLC found amounts of ca. 40 mg (7 - 8%) in tablets (> 70 analyzed) chosen at random from eight packs of the calendula-based phytotherapeutic product, purchased in the local market in Bucaramanga (Colombia). Conclusion: each analyzed tablet contained around 40 mg of the synthetic compound diclofenac (substance not declared in the product's label) and no tablet contained detectable amounts of esters of the triterpenoids oleanane or faradiol, which are calendula extract constituents that possess antiinflammatory activity; a few flavonoids that are common to many plants were found in amounts a thousand times smaller than that of diclofenac.

Metropolitan Atlanta Community Adolescent Rapid Testing Initiative: The impact of motivational interviewing and intensive case management on the psychosocial and clinical care outcomes of adolescents and young adults with HIV.

Early diagnosis and treatment are critical to preventing HIV-related complications and transmission for adolescents and young adults with HIV. The Metropolitan Atlanta Community Adolescent Rapid Testing Initiative (MACARTI) was a single-center, prospective, nonrandomized, interventional control group study incorporating motivational interviewing psychotherapy strategies with community outreach, HIV testing, and intensive case management. This substudy of MACARTI examined how the motivational interviewing and case management components influenced psychological distress, proactive coping, HIV/AIDS stress, and HIV stigma in association with HIV disease markers (HIV viral load and CD4+ T-cell counts). Ninety-eight adolescents and young adults with HIV (Mage = 21.5 ± 1.8, range 18-24) were allocated to either the standard of care (n = 49) or MACARTI (n = 49) arms, and results were compared between these two groups. Baseline and follow-up surveys measured psychological distress, proactive coping, HIV/AIDS stress, and HIV stigma. MACARTI arm assignment was associated with statistically significant reductions in psychological distress (p = .016), HIV/AIDS stress (p = .023), and the use of more reflective coping (p = .016) and strategic planning strategies (p = .001) during the first 6 months. These results did not remain significant at 1-year follow-up but may still provide support for the integration of psychotherapy strategies into HIV identification, linkage, and retention efforts in the future.

Acceptability and Barriers to HIV Pre-Exposure Prophylaxis in Atlanta's Adolescents and Their Parents.

Adolescents aged 13-24 years account for 23% of new HIV infections in Atlanta, indicating need for better HIV prevention strategies in this population. Pre-exposure prophylaxis (PrEP) is now approved for adolescent use. This study aims to understand the acceptability of and barriers to PrEP in adolescents and parents. We administered PrEP acceptability and barrier measures to HIV(-) 13-17 year olds and their parents from January to April 2016 in an adolescent clinic and emergency department in Atlanta, GA, stratifying by adolescent sexual activity. Acceptability scores (AS) and barrier scores (BS) were calculated by averaging survey answers 1-3. For AS, 1 was very unlikely to accept PrEP; concomitantly, BS near 3 indicated fewer barriers. Two-sample hypothesis testing, Pearson correlations, and linear regression were used. Of the 102 adolescent/parent dyads, 67% of adolescents were female, 94% black, with a mean age of 15.7 ± 1.5 years, and 31% were sexually active. Parents were 94% female, 96% black, with a mean age of 42.4 ± 8.9 years. AS averaged between somewhat to very likely to accept PrEP (2.4 ± 0.5 and 2.2 ± 0.6) in adolescents and parents, respectively. BS averaged between unlikely and somewhat likely to perceive barriers to PrEP (2.0 ± 0.4 and 1.9 ± 0.5) in adolescents and parents, respectively. The adolescent/parent dyad is likely to accept PrEP, regardless of sexual activity. Limitations include that nearly 70% of adolescents were not sexually active, and the study was conducted before PrEP approval by the Food and Drug Administration for those who are younger than 18 years. These results support future parent and adolescent education on PrEP.

Interest of Youth Living With HIV in Long-Acting Antiretrovirals.

OBJECTIVES: This study's primary objective was to characterize attitudes to long-acting antiretrovirals (LAARV), among youth aged 13-24 years living with perinatally acquired HIV and nonperinatally acquired HIV. Secondary objectives included: assessing whether those with detectable HIV RNA PCR viral load had higher enthusiasm for LAARV compared to those with suppressed viral load, and examining characteristics associated with LAARV enthusiasm. METHODS: A cross-sectional survey of 303 youth living with HIV (YHIV) followed at 4 pediatric/adolescent HIV clinics in the United States was performed to determine interest in LAARV, using a modified survey instrument previously used in adults. Interest in LAARV across groups was compared. Poisson regression with robust variance was used to determine the impact of various characteristics on interest in LAARV. FINDINGS: Overall, 88% of YHIV reported probable or definite willingness to use LAARV. The enthusiasm level was similar between youth with perinatally acquired HIV and nonperinatally acquired HIV (P = 0.93). Youth with HIV viral load >1000 copies per milliliter had significantly higher interest than youth with suppressed viral load [prevalence ratio 1.12 (95% confidence interval: 1.03 to 1.20); P = 0.005]. Female youth participants who had had past experience with implantable contraceptive methods had a significantly higher interest in LAARV (100% vs. 85.5%; P = 0.002). Proportion of respondents endorsing definite willingness to use was significantly higher with decreased injection frequency compared with increased injection frequency. INTERPRETATION: YHIV at 4 urban US pediatric/adolescent HIV clinics had high levels of enthusiasm for LAARV. LAARV should be given high priority as a potentially viable treatment option to improve clinical outcomes in YHIV.

Prevalence of Anal Squamous Intraepithelial Lesions in HIV-1-Infected Young Men Who Have Sex With Men and Transwomen.

OBJECTIVE: Anal cancer rates are increasing among HIV-infected persons. Although an efficacious human papillomavirus (HPV) vaccine is available, HPV vaccination rates remain low. Therefore, providers perform anal cancer screening, but there is no consensus on the optimal methods or timing of screening. This study was performed to determine the prevalence of and factors associated with anal squamous intraepithelial lesions in sexually active HIV-infected young men who have sex with men and transgender women. MATERIALS AND METHODS: We performed a single-center, retrospective study of sexually active HIV-infected young men who have sex with men and transgender women aged 13 to 24 years at an HIV clinic in Atlanta GA from 2009 to 2016. We used analysis of variance and χ tests of independence to evaluate bivariate associations and identify demographic, behavioral, and clinical risk factors. RESULTS: Of 314 subjects with a mean (SD) age of 20.4 (2.1) years at initial anal cytology testing, 5% had completed the HPV vaccine series at or before the time that cytology was obtained. Ninety-five percent of the anal cytology tests obtained were abnormal, and 72 (29%) of those subjects returned for diagnostic testing either by intraoperative biopsy or high-resolution anoscopy. Fifty-seven percent of those who underwent biopsy had histologic high-grade squamous intraepithelial lesions including 2 cases of carcinoma in situ. A history of greater than 20 lifetime sexual partners was associated with abnormal histology (probability < 0.001, p = .017). CONCLUSIONS: Our study highlights the value of early, standardized screening to avoid missing anal dysplasia or cancer, particularly in unvaccinated persons with high numbers of sexual partners.

Evaluating Facility Infrastructure for Prevention of Mother-to-Child Transmission of HIV-A 2015 Assessment of Major Delivery Hospitals in Atlanta, Georgia.

OBJECTIVE: Our goal was to evaluate the infrastructure of programs for the prevention of mother-to-child transmission (PMTCT) of human immunodeficiency virus (HIV) in major delivery units in the Atlanta, Georgia, metropolitan statistical area and to assess the knowledge, attitude, and practice of providers in these facilities around PMTCT. METHODS: Hospital assessments and individual knowledge and practices were surveyed among 71 healthcare providers from March 2015 to March 2016 in 11 hospitals that deliver 40000 infants annually, which represents 70% of all deliveries in the Atlanta metropolitan statistical area. Included were questions about HIV testing for mother-infant pairs, test result turnaround times, policies and procedures for PMTCT, opt-out versus opt-in testing, availability of rapid point-of-care testing on labor and delivery units, and postnatal prophylaxis. RESULTS: Seventy-three percent (8 of 11) of the hospitals had limitations in their PMTCT infrastructure, and 36% (4 of 11) reported no standardized policies for care of HIV-infected women. Three labor and delivery units used opt-in HIV testing of women. Only 27% (3 of 11) of the hospitals reported nucleic acid testing of HIV-exposed infants. Oral zidovudine for infant prophylaxis was available in all the hospitals, but 64% (7 of 11) of them did not stock nevirapine. Fifty-nine percent (24 of 44) of the obstetricians did not routinely offer rapid testing at delivery without a third-trimester HIV test, and 78% (n = 32 of 41) of them did not offer testing at delivery if the woman declined antenatal testing. The facility with the most annual births in Georgia did not offer rapid testing at delivery for women with an unknown HIV status. CONCLUSION: We identified several limitations in PMTCT infrastructure that might have contributed to perinatal HIV transmissions. The need to address these healthcare gaps to eliminate mother-to-child transmission of HIV in the United States is urgent.

A Genome-Scale Metabolic Reconstruction of Phytophthora infestans With the Integration of Transcriptional Data Reveals the Key Metabolic Patterns Involved in the Interaction of Its Host.

Phytophthora infestans, the causal agent of late blight disease, affects potatoes and tomatoes worldwide. This plant pathogen has a hemibiotrophic lifestyle, having an initial biotrophic infection phase during which the pathogen spreads within the host tissue, followed by a necrotrophic phase in which host cell death is induced. Although increasing information is available on the molecular mechanisms, underlying the distinct phases of the hemibiotrophic lifestyle, studies that consider the entire metabolic processes in the pathogen while undergoing the biotrophic, transition to necrotrophic, and necrotrophic phases have not been conducted. In this study, the genome-scale metabolic reconstruction of P. infestans was achieved. Subsequently, transcriptional data (microarrays, RNA-seq) was integrated into the metabolic reconstruction to obtain context-specific (metabolic) models (CSMs) of the infection process, using constraint-based reconstruction and analysis. The goal was to identify specific metabolic markers for distinct stages of the pathogen's life cycle. Results indicate that the overall metabolism show significant changes during infection. The most significant changes in metabolism were observed at the latest time points of infection. Metabolic activity associated with purine, pyrimidine, fatty acid, fructose and mannose, arginine, glycine, serine, and threonine amino acids appeared to be the most important metabolisms of the pathogen during the course of the infection, showing high number of reactions associated with them and expression switches at important stages of the life cycle. This study provides a framework for future throughput studies of the metabolic changes during the hemibiotrophic life cycle of this important plant pathogen.

Optimizing Community-Based HIV Testing and Linkage to Care for Young Persons in Metropolitan Atlanta.

HIV continuum of care analyses in Georgia during 2013 revealed that 82% of adolescents and adults living with HIV knew their diagnosis and that 75% were linked to care. However, of all persons in Georgia living with HIV in 2014, only 60% had at least one HIV care visit, and just 48% were retained in care. Understanding barriers for HIV testing, linkage, and retention in youth may strengthen HIV-related encounters and improve patient outcomes. We conducted 17 qualitative focus groups with HIV-positive and -negative youth, ages 18-24 years, from the Atlanta Metropolitan Statistical Area. Using computer-assisted thematic analyses, we examined focus group responses on ways to approach youth for community-based HIV testing and how service providers should discuss a new positive HIV diagnosis with youth. Of 68 participants, 85% were male, 90% were African American, 68% were HIV positive, and 50% had high school education or less. Mean age was 21.5 years (standard deviation: 1.8 years). Thematic analyses identified the following three key themes for approaching someone for HIV testing: (1) discretion, (2) being candid about testing, and (3) incentivizing testing. When service providers discuss an HIV positive test, participants recommended enhanced emotional support and reassurance of a potential healthy life span despite an HIV diagnosis. Community-based testing may be a viable option for increasing HIV screening of at-risk youth. Structuring an empathetic new diagnosis disclosure that addresses potential misconceptions and describes successful HIV treatment is essential to improving linkage to care among youth.

Social Capital, Depressive Symptoms, and HIV Viral Suppression Among Young Black, Gay, Bisexual and Other Men Who Have Sex with Men Living with HIV.

Social capital, the sum of an individual's resource-containing social network connections, has been proposed as a facilitator of successful HIV care engagement. We explored relationships between social capital, psychological covariates (depression, stigma and internalized homonegativity), and viral suppression in a sample of young Black gay, bisexual and other men who have sex with men (YB-GBMSM). We recruited 81 HIV-positive YB-GBMSM 18-24 years of age from a clinic setting. Participants completed a cross-sectional survey, and HIV-1 viral load (VL) measurements were extracted from the medical record. Sixty-five percent (65%) were virally suppressed (HIV-1 VL ≤ 40 copies/ml). Forty-seven percent (47%) had a positive depression screen. Depressive symptoms affected viral suppression differently in YB-GBMSM with lower vs. higher social capital (p = 0.046, test for statistical interaction between depression and social capital). The odds of viral suppression among YB-GBMSM with lower social capital was 93% lower among those with depressive symptoms (OR 0.07, p = 0.002); however, there was no association between depressive symptoms and viral suppression among those with higher social capital. Our results suggest that social capital may buffer the strong negative effects of depressive symptoms on clinical outcomes in YB-GBMSM living with HIV. In addition to treating depression, there is a role for interventions to augment social capital among YB-GBMSM living with HIV as a strategy for enhancing care engagement.

Regular Marijuana Use is Associated with Poor Viral Suppression in HIV-Infected Adolescents and Young Adults.

There is a paucity of data regarding the impact of drug use on HIV suppression and care retention among adolescents and young adults (AYAs). We recruited a clinic-based sample of HIV infected AYAs to assess the prevalence of self-reported drug use. Clinical data, including retention and viral suppression, were abstracted from the electronic medical record. Logistic regression was used to evaluate marijuana and illicit drug use associations and to identify other risk factors. Of 200 participants (mean age 21, 2.4 years, 69% horizontally infected), 46% reported current drug use, with marijuana as the most commonly used drug. Any illicit drug use (aOR 1.99, 95% CI 1.06-3.73, p = 0.032) and lower education (aOR 2.11, 95% CI 1.09-4.08, p = 0.046) were associated with poor viral suppression in multivariable analyses. Considering marijuana use only, an association with poor viral suppression was more pronounced (aOR 2.10, 95% CI 1.12-3.94, p = 0.021). Drug use did not have a significant association with retention in care, but AYAs who were retained in HIV care were less likely to have poorly suppressed HIV (aOR 0.22, 95% CI 0.10-0.49, p < 0.001). High prevalence of marijuana use among HIV infected AYAs, and its association with poorly suppressed HIV, demonstrates the need for intervention strategies to decrease its consumption.

The Metropolitan Atlanta community adolescent rapid testing initiative study: closing the gaps in HIV care among youth in Atlanta, Georgia, USA.

OBJECTIVE: To determine the effectiveness of the Metropolitan Atlanta community adolescent rapid testing initiative (MACARTI) intervention relative to standard of care (SOC), in achieving early diagnosis, linkage, and retention among HIV-infected youth ages 18-24 years. DESIGN: MACARTI was a pilot single-center, prospective, nonrandomized study. METHODS: MACARTI combined nontraditional venue HIV testing, motivational interviewing, and case management. We collected demographic, clinical variables and calculated linkage and appointment adherence rates. We obtained SOC data from an adolescent HIV clinic. Longitudinal data were analyzed using inverse propensity treatment-weighted linear growth models; medians, interquartile ranges (IQR), means, and 95% confidence intervals are provided. RESULTS: MACARTI screened 435 participants and identified 49 (11.3%) HIV infections. The SOC arm enrolled 49 new HIV-infected individuals. The 98 participants, (49 in each arm) were: 85% men; 91% Black; mean age = 21 years (SD : 1.8). Overall, 63% were linked within 3 months of diagnosis; linkage was higher for MACARTI compared to SOC (96 vs. 57%, P < 0.001). Median linkage time for MACARTI participants compared to SOC was 0.39 (IQR : 0.20-0.72) vs. 1.77 (IQR : 1.12-12.65) months (P < 0.001). MACARTI appointment adherence was higher than SOC (86.1 vs. 77.2%, P = 0.018). In weight-adjusted models, mean CD4 T-cell counts increased and mean HIV-1 RNA levels decreased in both arms over 12 months, but the differences were more pronounced in the MACARTI arm. CONCLUSION: MACARTI successfully identified and linked HIV-infected youth in Atlanta, USA. MACARTI may serve as an effective linkage and care model for clinics serving HIV-infected youth.

Sexually Transmitted Infections in Youth With Controlled and Uncontrolled Human Immunodeficiency Virus Infection.

BACKGROUND: Sexually transmitted infections (STIs), including human immunodeficiency virus (HIV), disproportionately affect adolescents and young adults (AYAs) ages 13-24 years. Sexually transmitted infections likewise are a risk factor for HIV acquisition and transmission; however, there is a lack of data on STI acquisition in HIV-infected AYAs. METHODS: We determined the incidence of STIs in HIV-infected AYAs 12.5 <25 years of age in the International Maternal Pediatric Adolescent AIDS Clinical Trials (IMPAACT) P1074 observational cohort study. Univariate and multivariable logistic regression models were used to evaluate the association of HIV control (mean viral load <500 copies/mL and CD4+ T cells >500 cells/mm3 in the year preceding STI diagnosis) and other risk factors with STI occurrence. RESULTS: Of 1201 enrolled subjects, 1042 participants met age criteria and were included (49% male, 61% black, 88% perinatally infected; mean age 18.3 years). One hundred twenty participants had at least 1 STI on study, of whom 93 had their first lifetime STI (incidence rate = 2.8/100 person-years). For individual STI categories, 155 incident category-specific events were reported; human papillomavirus (HPV) and chlamydial infections were the most common. In the multivariable model, having an STI was associated with older age (adjusted odds ratio [aOR] = 1.13; 95% confidence interval [CI], 1.05-1.22), female sex (aOR = 2.65; 95% CI, 1.67-4.21), nonperinatal HIV acquisition (aOR = 2.33; 95% CI, 1.29-4.22), and uncontrolled HIV infection (aOR = 2.05; 95% CI, 1.29-3.25). CONCLUSIONS: Sexually transmitted infection acquisition in HIV-infected AYAs is associated with older age, female sex, nonperinatal HIV acquisition, and poorly controlled HIV infection. Substantial rates of STIs among HIV-infected AYAs support enhanced preventive interventions, including safe-sex practices and HPV vaccination, and antiretroviral adherence strategies.
