RESUMO

Extracellular vesicles (EVs) are important players in melanoma progression, but their use as clinical biomarkers has been limited by the difficulty of profiling blood-derived EV proteins with high depth of coverage, the requirement for large input amounts, and complex protocols. Here, we provide a streamlined and reproducible experimental workflow to identify plasma- and serum- derived EV proteins of healthy donors and melanoma patients using minimal amounts of sample input. SEC-DIA-MS couples size-exclusion chromatography to EV concentration and deep-proteomic profiling using data-independent acquisition. From as little as 200 µL of plasma per patient in a cohort of three healthy donors and six melanoma patients, we identified and quantified 2896 EV-associated proteins, achieving a 3.5-fold increase in depth compared to previously published melanoma studies. To compare the EV-proteome to unenriched blood, we employed an automated workflow to deplete the 14 most abundant proteins from plasma and serum and thereby approximately doubled protein group identifications versus native blood. The EV proteome diverged from corresponding unenriched plasma and serum, and unlike the latter, separated healthy donor and melanoma patient samples. Furthermore, known melanoma markers, such as MCAM, TNC, and TGFBI, were upregulated in melanoma EVs but not in depleted melanoma plasma, highlighting the specific information contained in EVs. Overall, EVs were significantly enriched in intact membrane proteins and proteins related to SNARE protein interactions and T-cell biology. Taken together, we demonstrated the increased sensitivity of an EV-based proteomic workflow that can be easily applied to larger melanoma cohorts and other indications.

RESUMO

BACKGROUND: Condyloma acuminatum is caused by human papillomavirus (HPV), which typically presents as excrescent, pedunculated, papillomatous lesions which may be of a pale colour. On rare occasions, we have observed pigmented genital lesions that are similar to seborrhoeic keratoses, but with histological findings of condyloma acuminatum and positive genotyping for HPV. We have termed these 'seborrhoeic keratosis-like' type condylomas. METHODS: This is an observational retrospective study. The following clinical data were collected: age, sex, time of evolution, location, isolated or multiple lesions, monomorphous or polymorphous/mixed lesions. HPV genotyping was performed in all cases, and excision for histological study in eight cases. RESULTS: A total of 31 patients were diagnosed with this type of pigmented condylomata acuminata. Of these, 16 had isolated lesions (less than five lesions) and 15 had multiple lesions. 67% of the lesions exhibited slow growth, with an evolution period of greater than 1 year. The most frequent location was the base of the penis and pubis. HPV genotyping of the lesions was positive in all cases, with the HPV-6 genotype predominating (28 cases, 90.3%). The lesions exhibited dermoscopic differences from other pigmented lesions and histological findings attributable to HPV infection (pseudoparakeratosis, koilocytosis, etc) and others similar to those observed in seborrhoeic keratoses. CONCLUSIONS: A total of 31 patients were diagnosed with pigmented verrucous lesions, excrescents, isolated or multiple, in the genital region. These lesions exhibited clinical characteristics similar to seborrhoeic keratoses, with positive genotyping for HPV. In the majority of cases, the genotype was HPV-6. These lesions have been named 'pigmented condylomata acuminata seborrhoeic keratosis-like'. Only 10 cases of these lesions have been described in the literature.

RESUMO

The CDC recommends that persons aged 13-64 receive an HIV test at least once in their lifetime and that some groups test annually or more frequently. Nearly one-half of US Latino immigrants have never been tested for HIV. To the extent that immigration-related laws deter documented and undocumented immigrants from engaging in communicable disease control measures, these laws undermine public health efforts. 1750 noncitizen adult, sexually active, Spanish-speaking Latino immigrants across four cities in the US completed a cross-sectional survey assessing perceptions of immigration-related laws and immigration consequences related to HIV testing and diagnosis. Participants were recruited in-person by staff in community settings, through flyers posted in places frequented by Latino immigrants, and by word-of-mouth through snowball sampling. Outcomes were whether participants had ever received an HIV test and whether they tested in the previous 12 months. Multivariable analyses examined the relative contribution of perceived immigration laws and consequences on HIV testing behaviors when considering established predictors of HIV testing. Perceptions of HIV-related immigration laws and immigration consequences was a significant predictor of never having had an HIV test even when considered relative to common predictors of HIV testing. The influence of perceived immigration laws and consequences on testing in the previous 12 months was not significant in multivariable analysis. Perceived HIV-related immigration laws and consequences appear to be a substantial contributor to reluctance to be tested for HIV among Latino immigrants who have never been tested. Effective interventions should be developed to address these.


RESUMEN: El CDC recomienda que las personas de 13 a 64 años se hagan una prueba del VIH al menos una vez en la vida y que algunos grupos se hagan la prueba anualmente o con mayor frecuencia. Casi la mitad de los inmigrantes latinos de los Estados Unidos nunca se han hecho la prueba del VIH. En la medida en que las leyes relacionadas con la inmigración disuadan a los inmigrantes documentados e indocumentados de participar en medidas de control de enfermedades transmisibles, estas leyes socavan los esfuerzos de salud pública. 1750 inmigrantes latinos adultos no ciudadanos, sexualmente activos y de habla hispana en cuatro ciudades de EE. UU. completaron una encuesta transversal que evaluó las percepciones de las leyes relacionadas con la inmigración y de las consecuencias de la inmigración relacionadas con las pruebas y el diagnóstico del VIH. Los participantes fueron reclutados en persona en contextos comunitarios, a través de volantes publicados en lugares frecuentados por inmigrantes latinos y de boca en boca a través de muestras de bola de nieve. Las variables dependientes fueron si los participantes se habían hecho una prueba del VIH alguna vez y si se habían hecho la prueba en los últimos 12 meses. Los análisis multivariados examinaron la contribución relativa de la percepción de las leyes de inmigración y de las consecuencias de inmigración sobre los comportamientos relativo a las pruebas del VIH, controlando por predictores conocidos de las pruebas del VIH. Las percepciones de las leyes de inmigración relacionadas con el VIH y las consecuencias de la inmigración fueron un predictor significativo de nunca haberse realizado una prueba del VIH, aun considerando los predictores comunes de la prueba del VIH. La influencia de la percepción de las leyes de inmigración y de las consecuencias de la inmigración sobre la prueba en los últimos 12 meses no fue significativa en el análisis multivariado. Las leyes de inmigración y las consecuencias percibidas relacionadas con el VIH parecen contribuir sustancialmente a la renuencia a hacerse la prueba del VIH entre los inmigrantes latinos que nunca se han hecho la prueba. Deben desarrollarse intervenciones efectivas para abordar esta renuencia.

RESUMO

INTRODUCTION: The United States is currently facing an opioid overdose crisis. Research suggests that multiple interventions are needed to reduce overdose deaths including increasing access and retention to medications to treat opioid use disorders (MOUD, i.e., methadone, buprenorphine, and naltrexone) and increasing the distribution and use of naloxone, a medication that can reverse the respiratory depression that occurs during opioid overdoses. However, barriers to MOUD initiation and retention persist and discontinuations of MOUD carry a heightened risk of overdose. Many times, MOUD is not sought as a first line of treatment by people with opioid use disorder (OUD), many of whom seek treatment from medically managed withdrawal (detox) programs. Among those who do initiate MOUD, retention is generally low. The present study examines the treatment experiences of people who use opioids in three states, Connecticut, Kentucky, and Wisconsin. METHODS: We conducted in-depth interviews with people who use opioids in a rural, urban, and suburban area of three states: Connecticut, Kentucky and Wisconsin. Data analysis was collaborative and key themes were identified through multiple readings, coding of transcripts and discussion with all research team members. RESULTS: Results reveal a number of systemic issues that reduce the likelihood that people initiate and are retained on MOUD including the ubiquity of detox as a first step in drug treatment, abstinence requirements and requiring patients to attend group treatment. MOUD-related stigma was a significant factor in the kinds of treatment participants chose and their experiences in treatment. CONCLUSIONS: Interventions to reduce MOUD stigma are needed to encourage MOUD as a first course of treatment. Eliminating abstinence-based rules for MOUD treatment may improve treatment retention and decrease overdose risk.

RESUMO

Intersectional stigma and discrimination have increasingly been recognized as impediments to the health and well-being of young Black sexual minority men (YBSMM) and transgender women (TW). However, little research has examined the relationship between intersectional discrimination and HIV pre-exposure prophylaxis (PrEP) outcomes. This study with 283 YBSMM and TW examines the relationship between intersectional discrimination and current PrEP use and likelihood of future PrEP use. Path models were used to test associations between intersectional discrimination, resilience and social support, and PrEP use and intentions. Individuals with higher levels of anticipated discrimination were less likely to be current PrEP users (OR = 0.59, p = .013), and higher levels of daily discrimination were associated with increased likelihood of using PrEP in the future (B = 0.48 (0.16), p = .002). Greater discrimination was associated with higher levels of resilience, social support, and connection to the Black LGBTQ community. Social support mediated the effect of day-to-day discrimination on likelihood of future PrEP use. Additionally, there was a significant and negative indirect effect of PrEP social concerns on current PrEP use via Black LGBTQ community connectedness. The results of this study highlight the complexity of the relationships between discrimination, resilience, and health outcomes.

RESUMO

BACKGROUND: Poor physical access to health facilities could increase the likelihood of undetected intimate partner violence (IPV) during pregnancy. We aimed to determine sub-regional differences and associations between spatial accessibility to health facilities and IPV among pregnant women in Uganda. METHOD: Weighted cross-sectional analyses were conducted using merged 2016 Uganda Demographic and Health Survey and 2014 Uganda Bureau of Statistics health facility datasets. Our study population were 986 women who self-reported being currently pregnant and responded to IPV items. Outcome was spatial accessibility computed as the near point linear distance [< 5 km (optimal) vs. ≥ 5 km (low)] between women's enumeration area and health facility according to government reference cutoffs. Primary independent variable (any IPV) was defined as exposure to at least one of physical, emotional, and sexual IPV forms. Logistic regression models were sequentially adjusted for covariates in blocks based on Andersen's behavioral model of healthcare utilization. Covariates included predisposing (maternal age, parity, residence, partner controlling behavior), enabling (wealth index, occupation, education, economic empowerment, ANC visit frequency), and need (wanted current pregnancy, difficulty getting treatment money, afraid of partner, and accepted partner abuse) factors. RESULTS: Respondents' mean age was 26.1 years with ± 9.4 standard deviations (SD), mean number of ANC visits was 3.8 (± 1.5 SD) and 492/986 (49.9%) pregnant women experienced IPV. Median spatial accessibility to the nearest health facility was 4.1 km with interquartile range (IQR) from 0.2 to 329.1 km. Southwestern, and Teso subregions had the highest average percentage of pregnant women experiencing IPV (63.8-66.6%) while Karamoja subregion had the highest median spatial accessibility (7.0 to 9.3 km). In the adjusted analysis, pregnant women exposed to IPV had significantly higher odds of low spatial accessibility to nearest health facilities when compared to pregnant women without IPV exposure after controlling for enabling factors in Model 2 (aOR 1.6; 95%CI 1.2, 2.3) and need factors in Model 3 (aOR 1.5; 95%CI 1.1, 3.8). CONCLUSIONS: Spatial accessibility to health facilities were significantly lower among pregnant women with IPV exposure when compared to those no IPV exposure. Improving proximity to the nearest health facilities with ANC presents an opportunity to intervene among pregnant women experiencing IPV. Focused response and prevention interventions for violence against pregnant women should target enabling and need factors.

RESUMO

BACKGROUND: Intimate partner violence (IPV) remains a pervasive form of gender-based violence (GBV) that is largely undisclosed, especially among women seeking healthcare services in Uganda. Prioritizing survivor needs may improve IPV disclosure. This study explores healthcare worker experiences from provider-patient interactions with survivors seeking antenatal care services (ANC) in Uganda. METHODS: In-depth interviews were conducted among twenty-eight experienced healthcare providers in a rural and an urban-based ANC clinic in Eastern and Central Uganda. Providers were asked what they viewed as the needs and fears of women identified as having experienced any form of IPV. Iterative, inductive/deductive thematic analysis was conducted to discover themes regarding perceived needs, fears, and normalizing violence experienced by IPV survivors. RESULTS: According to healthcare providers, IPV survivors are unaware of available support services, and have need for support services. Providers reported that some survivors were afraid of the consequences of IPV disclosure namely, community stigma, worries about personal and their children's safety, retaliatory abuse, fear of losing their marriage, and partners' financial support. Women survivors also blamed themselves for IPV. Contextual factors underlying survivor concerns included the socio-economic environment that 'normalizes' violence, namely, some cultural norms condoning violence, and survivors' unawareness of their human rights due to self-blame and shame for abuse. CONCLUSIONS: We underscore a need to empower IPV survivors by prioritizing their needs. Results highlight opportunities to create a responsive healthcare environment that fosters IPV disclosure while addressing survivors' immediate medical and psychosocial needs, and safety concerns. Our findings will inform GBV prevention and response strategies that integrate survivor-centered approaches in Uganda.

RESUMO

To make informed COVID-19 related decisions, individuals need information about their personal risks and how those risks may vary with specific demographic and health characteristics. The Fight COVID Milwaukee web-based risk assessment tool allows for assessment of COVID-19 mortality risk as a function of personal and neighborhood characteristics. The purpose of this study is to explore public understanding of this risk assessment tool and risk perception through community focus groups. Individuals were recruited from the general adult population in Milwaukee County, Wisconsin, USA, to participate in nine online focus groups where the risk assessment tool was presented for feedback. Three main themes were identified in the focus groups regarding the web-based risk assessment tool: some challenges in accessibility, variable ease of understanding, and personal usefulness but uncertain value for others. This paper explores how members of the community interpret individual risk assessments and life expectancy estimations, and how these vary with age, gender, race/ethnicity, socioeconomic status, and pre-existing comorbidities.

RESUMO

BACKGROUND: Optimal utilization of antenatal care (ANC) services improves positive pregnancy experiences and birth outcomes. However, paucity of evidence exists on which factors should be targeted to increase ANC utilization among women experiencing intimate partner violence (IPV) in Uganda. OBJECTIVE: To determine the independent association between IPV exposure and ANC utilization as well as the predictors of ANC utilization informed by Andersen's Behavioral Model of Healthcare Utilization. METHODS: We analyzed 2016 Uganda Demographic and Health Survey data that included a sample of 1,768 women with children aged 12 to 18 months and responded to both ANC utilization and IPV items. Our outcome was ANC utilization, a count variable assessed as the number of ANC visits in the last 12 months preceding the survey. The key independent variable was exposure to any IPV form defined as self-report of having experienced physical, sexual and/or emotional IPV. Covariates were grouped into predisposing (age, formal education, religion, problem paying treatment costs), enabling (women's autonomy, mass media exposure), need (unintended pregnancy, parity, history of pregnancy termination), and healthcare system/environmental factors (rural/urban residence, spatial accessibility to health facility). Poisson regression models tested the independent association between IPV and ANC utilization, and the predictors of ANC utilization after controlling for potential confounders. RESULTS: Mean number of ANC visits (ANC utilization) was 3.71 visits with standard deviation (SD) of ± 1.5 respectively. Overall, 60.8% of our sample reported experiencing any form of IPV. Any IPV exposure was associated with lower number of ANC visits (3.64, SD ± 1.41) when compared to women without IPV exposure (3.82, SD ± 1.64) at p = 0.013. In the adjusted models, any IPV exposure was negatively associated with ANC utilization when compared to women with no IPV exposure after controlling for enabling factors (Coef. -0.03; 95%CI -0.06,-0.01), and healthcare system/environmental factors (Coef. -0.06; 95%CI -0.11,-0.04). Predictors of ANC utilization were higher education (Coef. 0.27; 95%CI 0.15,0.39) compared with no education, high autonomy (Coef. 0.12; 95%CI 0.02,0.23) compared to low autonomy, and partial media exposure (Coef. 0.06; 95%CI 0.01,0.12) compared to low media exposure. CONCLUSION: Addressing enabling and healthcare system/environmental factors may increase ANC utilization among Ugandan women experiencing IPV. Prevention and response interventions for IPV should include strategies to increase girls' higher education completion rates, improve women's financial autonomy, and mass media exposure to improve ANC utilization in similar populations in Uganda.

RESUMO

OBJECTIVES: We examined Latinx immigrants' perceptions of US policy related to restrictions on immigrants' use of public resources and their thoughts about the influence of these on immigrants' healthcare utilization. DESIGN: A series of 16 focus group discussions with Latinx immigrant men and women (documented and undocumented) (N = 130) were conducted between May and July 2017 across four US cities. RESULTS: Four central themes emerged: participants attributed the limited resources available for affordable healthcare for many uninsured US immigrants (both documented and undocumented) to the US government's view of immigrants as burdens on public resources and its subsequent unwillingness to dedicate funds for their care; participants expressed concerns, some unfounded, about negative immigration ramifications arising from diagnosis with health conditions perceived to be serious and/or expensive to treat; participants noted that some immigrants avoided using health programs and services to which they were entitled because of immigration concerns; finally, participants described how access to information on immigration laws and healthcare resources, and conversely, misinformation about these, influenced healthcare utilization. CONCLUSIONS: Participants were acutely aware of the image of immigrants as public charges or potential burdens on government resources that underlies US immigration policy. In some cases, participants came to inaccurate and potentially harmful conclusions about the substance of laws and regulations based on their beliefs about the government's rejection of immigrants who may burden public resources. This underscores the importance of ensuring that immigrants have access to information on immigration-related laws and regulations and on healthcare resources available to them. Participants noted that access to information also fostered resilience to widespread misinformation. Importantly, however, participants' beliefs had some basis in US immigration policy discourse. Law and policy makers should reconsider legislation and political commentary that frame self-reliance, the guiding principle of US immigration policy, in terms of immigrants' use of publicly funded healthcare resources.

RESUMO

BACKGROUND: Antegrade intramedullary nailing in humeral shaft fracture has been abandoned by certain orthopedic surgeons because of rotator cuff injury caused by first- and second-generation intramedullary nails (IMNs). However, only a few studies have specifically addressed the results of antegrade nailing for the treatment of humeral shaft fractures with a straight third-generation IMN; thus, complications need to be re-evaluated. We hypothesized that fixation of displaced humeral shaft fractures with a straight third-generation antegrade IMN with the percutaneous technique avoid shoulder problems (stiffness and pain) incurred by first- and second-generation IMNs. METHODS: This was a retrospective, single-center, nonrandomized study of 110 patients with a displaced humeral shaft fracture between 2012 and 2019 treated surgically with a long third-generation straight IMN. Mean follow-up was 35.6 months (range, 15-44 months). RESULTS: There were 73 women and 37 men with a mean age of 64.7 ± 19 years. All fractures were closed (37.3% 12A1, 13.6% 12B2, and 13.6% 12B3 AO/OTA classification). Mean Constant score was 82 ± 19, Mayo Elbow Performance Score 96 ± 11 and the mean EQ-5D visual analog scale score was 69.7 ± 21.5. Mean forward elevation 150° ± 40°, abduction 148° ± 45°, and external rotation 38° ± 15°. Symptoms associated with rotator cuff disease were present in 6.4%. Evidence of radiographic fracture healing was detected in all but 1 case. One postoperative nerve injury and 1 adhesive capsulitis were present. Overall, 6.3% underwent second surgeries (4.5% were minor surgeries like hardware removal). CONCLUSION: Percutaneous antegrade intramedullary nailing of humeral shaft fractures with a straight third-generation nail considerably reduced complications related to shoulder problems and achieved good functional results.

RESUMO

Objectives. To investigate resilience strategies used by Black gay, bisexual, and other men who have sex with men (MSM) to navigate racism and heterosexism. Methods. In 2019, we conducted in-depth interviews with 46 Black MSM in Milwaukee, Wisconsin, and Cleveland, Ohio. Thematic analysis, informed by intersectionality, was used to identify intersectional resilience within the context of participants' lives. Results. Our analyses revealed ways in which Black MSM respond to stigma and oppression. We identified the following themes that capture these experiences: pride in intersectional identities, perseverance, community advocacy, and social support. Our analyses reveal how men draw on these assets and resources to positively adapt despite experiences of racism and heterosexism. Conclusions. Intersectional resilience can support Black MSM in navigating racism and heterosexism. However, public health interventions at the institutional and system levels are needed to directly target the root causes of oppression and support resources that facilitate intersectional resilience.

RESUMO

People who use crack cocaine (PWUCC) are a population severely impacted by a concentrated epidemic of HIV. Behavioral interventions to prevent and treat HIV among PWUCC have been implemented around the world including in low- and middle-income countries which have been disproportionately affected by HIV. However, few studies have validated and assessed psychometric properties of measures on PWUCC, especially in transnational populations. Our sample was comprised of 1324 PWUCC, Spanish mono-lingual speakers, residing in the metropolitan area of San Salvador, El Salvador. Exploratory factor analysis and subsequent confirmatory factor analysis using statistical softwares SPSS and Amos were conducted on three abbreviated and translated condom use attitude measures (i.e., Condom Use Attitudes Scale-Spanish Short Form, Condom Use Social Norm-Spanish Short Form [CUSN-SSF], Condom Use Self-Efficacy-Spanish Short Form). Convergent validity was examined by computing bivariate correlations between the scales and condom use and sexually transmitted disease diagnosis. Results indicated that a two-factor, 8-item correlated model for the CUAS-SSF scale had an excellent fit and adequate reliability (α = .76). The confirmatory factor analysis for the 5-item CUSN-SSF scale indicated a satisfactory fit with 3 of 6 fit indices indicating adequate fit. Analysis of the two-factor 5-item CUSE-SSF scale indicated satisfactory fit and adequate reliability (α = .84). There were significant correlations between all measures and with self-reported condom use. Results indicate that these brief measures are reliable and valid and can be utilized to assess the effectiveness of HIV risk reduction interventions among Spanish-speaking PWUCC.

RESUMO

Prior research has highlighted the impact of the COVID-19 pandemic on HIV prevention services within the U.S., but few studies have explored this impact through an exploratory, qualitative lens. In this study, we sought to highlight the voices of young sexual minority men (YSMM) 17-24 years old and explored the perceived impact of the pandemic on HIV prevention among a diverse, nationwide sample of YSMM who participated in synchronous online focus group discussions between April and September 2020. Forty-one YSMM described the negative effects of the COVID-19 pandemic on HIV testing and prevention services, including limited and disrupted access to HIV testing, HIV pre-exposure prophylaxis (PrEP), and HIV post-exposure prophylaxis. COVID-19-related challenges were compounded by ongoing, pre-COVID-19 barriers experienced by YSMM in the U.S. For instance, many YSMM relocated back home with family, causing men to avoid HIV prevention services for fear of outing themselves to relatives. YSMM also worried about placing their family at increased risk of COVID-19 by attending clinical appointments. YSMM who did seek HIV prevention services, including access to PrEP, experienced significant barriers, including limited appointment availability and services not tailored to YSMM. Further efforts are needed to support YSMM re-engaging in HIV prevention during and after the COVID-19 era.

RESUMO

BACKGROUND: Prevention of opioid-involved overdose deaths remains a public health priority in the United States. While expanding access to naloxone is a national public health strategy, it is largely implemented at the state and local level, where significant variability in policies, resources, and norms exist. The aims of the current study were to examine the social context of naloxone access in three different states (Connecticut, Kentucky, Wisconsin) from the perspectives of key informants (first responders, harm reduction personnel, and pharmacists), who play some role in dispensing or administering naloxone within their communities. METHODS: Interviews were conducted with key informants who were in different local areas (urban, suburban, rural) across Connecticut, Kentucky, and Wisconsin. Interview guides explored the key informants' experiences with administering or dispensing naloxone, and their perspectives on opioid overdose prevention efforts in their areas. Data analysis was conducted using multistage inductive coding and comparative methods to identify dominant themes within the data. RESULTS: Key informants in each of the three states noted progress toward expanding naloxone access, especially among people who use opioids, but also described inequities. The key role of harm reduction programs in distributing naloxone within their communities was also highlighted by participants, as well as barriers to increasing naloxone access through pharmacies. Although there was general consensus regarding the effectiveness of expanding naloxone access to prevent overdose deaths, the results indicate that communities are still grappling with stigma associated with drug use and a harm reduction approach. CONCLUSION: Findings suggest that public health interventions that target naloxone distribution through harm reduction programs can enhance access within local communities. Strategies that address stigmatizing attitudes toward people who use drugs and harm reduction may also facilitate naloxone expansion efforts, overall, as well as policies that improve the affordability and awareness of naloxone through the pharmacy.

BACKGROUND: Uganda clinical guidelines recommend routine screening of pregnant women for intimate partner violence (IPV) during antenatal care (ANC). Healthcare providers play a critical role in identifying IPV during pregnancy in ANC clinics. This study explored facilitators and barriers for IPV screening during pregnancy (perinatal IPV screening) by ANC-based healthcare workers in Uganda. METHODS: We conducted qualitative in-depth interviews among twenty-eight purposively selected healthcare providers in one rural and an urban-based ANC health center in Eastern and Central Uganda respectively. Barriers and facilitators to IPV screening during ANC were identified iteratively using inductive-deductive thematic analysis. RESULTS: Participants had provided ANC services for a median (IQR) duration of 4.0 (0.1-19) years. Out of 28 healthcare providers, 11 routinely screened women attending ANC clinics for IPV and 10 had received IPV-related training. Barriers to routine IPV screening included limited staffing and space resources, lack of comprehensive gender-based violence (GBV) training and provider unawareness of the extent of IPV during pregnancy. Facilitators were availability of GBV protocols and providers who were aware of IPV (or GBV) tools tended to use them to routinely screen for IPV. Healthcare workers reported the need to establish patient trust and a safe ANC clinic environment for disclosure to occur. ANC clinicians suggested creation of opportunities for triage-level screening and modification of patients' ANC cards used to document women's medical history. Some providers expressed concerns of safety or retaliatory abuse if perpetrating partners were to see reported abuse. CONCLUSIONS: Our findings can inform efforts to strengthen GBV interventions focused on increasing routine perinatal IPV screening by ANC-based clinicians. Implementation of initiatives to increase routine perinatal IPV screening should focus on task sharing, increasing comprehensive IPV training opportunities, including raising awareness of IPV severity, trauma-informed care and building trusting patient-physician relationships.

RESUMO

BACKGROUND: Providing permanent supportive housing to chronically homeless persons living with human immunodeficiency virus (PLH) contributes to improved human immunodeficiency virus (HIV) outcomes, including adherence to antiretroviral therapy (ART). This study seeks to understand whether certain components of housing, namely intensity of case management and specialized HIV housing programs, affects ART adherence for PLH in supportive housing. METHODS: From 2015 to 2019 we conducted quantitative assessments with 157 PLH in supportive housing at baseline, 6-, 12-, and 18-month postbaseline to identify factors associated with ART adherence. General Estimating Equations for repeated measures were performed to assess bivariate and multivariate measures. RESULTS: Two thirds of PLH in supportive housing reported 95% or greater adherence to ART. Multivariate analyses indicate that neither intensity of case management services nor specialized housing for PLH were associated with greater ART adherence. Greater time since diagnosis was positively associated with ART adherence. Greater depressive symptoms and African American race were negatively associated with ART adherence. CONCLUSIONS: Study findings reveal that although prior research has established the importance of receipt of housing for homeless PLH, the type or intensity of case management services associated with that housing may not be as important as simply being housed. Our results highlight the importance of considering mental health and more recent HIV diagnosis when developing treatment and case management plans to enhance residents' ART adherence.

RESUMO

Black women contract HIV at much higher rates than White or Hispanic women. Pre-exposure prophylaxis (PrEP) is an underutilized prevention tool among this population. We sought to determine participants' interest in PrEP and facilitators and barriers to PrEP adoption. This longitudinal, qualitative study included 30 Black women (Mage = 32.2) interviewed 4 times over 6 months. Most participants had never heard of PrEP and a majority expressed initial interest. Barriers to PrEP initiation included low perceived HIV risk, medical mistrust, provider experiences and knowledge, negative reactions from family and friends, low perceived efficacy to adherence, and transportation. This study demonstrated actual, rather than hypothetical, PrEP interest and attitudes among Black women, and the barriers that arose over time during the study. PrEP awareness needs to be promoted among Black women and medical providers. Future research should address individual risk perception, medical mistrust, increasing social support, and decreasing transportation barriers.


RESUMEN: Las mujeres negras contraen el VIH en tasas mucho más altas que las mujeres blancas o hispanas. La profilaxis de preexposición al VIH (PrEP) es una herramienta de prevención infrautilizada entre esta población. Buscamos determinar el interés de las participantes en la PrEP y los facilitadores y las barreras para la adopción de la PrEP. Este estudio longitudinal y cualitativo incluyó a 30 mujeres negras (Mage = 32,2) entrevistadas 4 veces durante 6 meses. La mayoría de las participantes nunca habían oído hablar de la PrEP y la mayoría expresó un interés inicial. Las barreras para el inicio de la PrEP incluyeron un bajo riesgo percibido de VIH, desconfianza médica, experiencias y conocimientos del proveedor, reacciones negativas de familiares y amigos, baja eficacia percibida para la adherencia, y transporte. Este estudio demostró intereses y actitudes reales, más que hipotéticos, sobre la PrEP entre las mujeres negras, y las barreras que surgieron con el tiempo durante el estudio. Se debe promover la concienciación sobre la PrEP entre las mujeres negras y los proveedores médicos. Las investigaciones futuras deben abordar la percepción del riesgo individual, la desconfianza médica, el aumento del apoyo social, y la disminución de las barreras del transporte.

RESUMO

The present study evaluates a combination prevention intervention for crack users in San Salvador, El Salvador that included social network HIV testing, community events and small group interventions. We examined the cumulative effects of the social network HIV testing and small group interventions on rates of HIV testing, beyond the increase that we saw with the introduction of the social network HIV testing intervention alone. HIV test data was converted into the number of daily tests and analyzed the immediate and overtime impact of small group interventions during and in the twelve weeks after the small group intervention. The addition of the small group interventions to the baseline of monthly HIV tests resulted in increased rates of testing lasting 7 days after the small group interventions suggesting a reinforcing effect of small group interventions on testing rates.

RESUMO

Objectives: Latinos in the United States experience a disproportionate number of HIV and other sexually transmitted infections (STIs) and higher use of alcohol and illegal drugs, which has been attributed to increases in risk behaviors following immigration. Whereas substantial research documents these behavioral changes, little is known about how immigrants increase their risk or why some immigrants increase their risk and other immigrants do not. This study explored how the social and normative context affects sexual and substance use behaviors among Latino immigrant men in a midsized Midwestern city of the United States.Methods: We interviewed 64 Latino immigrant men recruited from community sites in Milwaukee, Wisconsin (mean age = 32.6 years). Participants reported the social and normative contexts preceding and following immigration, including social networks and support, perceptions of the law, and familiar and peer normative influences.Results: Immigrants attributed changes in their sexual and substance use behaviors to their immigration goals, social support, peer and familial normative influences, and restrictions related to their immigrant status. Immigration for economic and personal advancement was generally protective from behaviors that would interfere with those goals as were extended familial networks that could provide support, resources, and normative control. The need to stay under the radar of authorities, the proportion of Latinos in the community, the social and normative changes associated with immigrants' age, and the higher perceptions of risk for HIV in the United States compared with their home countries also influenced immigrants' sexual and substance use behaviors.Conclusions: Changes in risk behavior after immigration to the United States reflect a combination of social and normative factors and personal goals. Interventions and policies aiming to prevent HIV and substance use among Latino immigrants should understand the contextual conditions that decrease or increase their risk behaviors in the United States.
