RESUMO

BACKGROUND: There is an urgent need to increase diversity among scientific investigators in the HIV research field to be more reflective of communities highly affected by the HIV epidemic. Thus, it is critical to promote the inclusion and advancement of early-stage scholars from racial and ethnic groups underrepresented in HIV science and medicine. METHODS: To widen the HIV research career pathway for early-stage scholars from underrepresented minority groups, the National Institutes of Health supported the development of the Centers for AIDS Research (CFAR) Diversity, Equity, and Inclusion Pathway Initiative (CDEIPI). This program was created through partnerships between CFARs and Historically Black Colleges and Universities and other Minority Serving Institutions throughout the United States. RESULTS: Seventeen CFARs and more than 20 Historically Black Colleges and Universities and Minority Serving Institutions have participated in this initiative to date. Programs were designed for the high school (8), undergraduate (13), post baccalaureate (2), graduate (12), and postdoctoral (4) levels. Various pedagogical approaches were used including didactic seminar series, intensive multiday workshops, summer residential programs, and mentored research internship opportunities. During the first 18 months of the initiative, 257 student scholars participated in CDEIPI programs including 150 high school, 73 undergraduate, 3 post baccalaureate, 27 graduate, and 4 postdoctoral students. CONCLUSION: Numerous student scholars from a wide range of educational levels, geographic backgrounds, and racial and ethnic minority groups have engaged in CDEIPI programs. Timely and comprehensive program evaluation data will be critical to support a long-term commitment to this unique training initiative.

RESUMO

BACKGROUND: To include, sustain, and retain HIV-focused early career faculty from groups historically excluded from biomedical research, the Providence/Boston Center for AIDS Research (CFAR) conducted focus groups and individual interviews with early and mid-career faculty to discern their needs. METHODS: We conducted focus groups and interviews with 15 faculty at institutions affiliated with Providence/Boston CFAR from groups underrepresented in biomedical research. The discussion was guided using the domains of an Asset Bundle Model encompassing scientific human capital, social capital, and financial capital. RESULT: Participants' identities, including their race, ethnicity, gender, sexual orientation, and being a parent affected their vision of themselves as scientists. Participants reported confusion or limited training on or access to resources for professional development, hiring staff, meeting NIH reporting requirements, international research, support for working parents, sabbaticals, and addressing workplace conflict or unsupportive work environments. Some described feeling like they were a burden on their mentors who seemed overextended. They identified attributes of effective mentors, such as believing in and investing in the mentee; having the requisite content area expertise and self-confidence; being able to identify mentees needs and meet them where they are; and being consistent, communicative, respectful, and kind. They described a need for additional education and support preresearch and postresearch grant award management. CONCLUSIONS: To learn how to equitably serve all interested in HIV research, CFARs should engage and include perspectives from scientists who have historically been excluded from biomedical research. Our future work will test, implement, and disseminate the ideas generated by these focus group discussions.

RESUMO

In the field of regulatory science, reviewing literature is an essential and important step, which most of the time is conducted by manually reading hundreds of articles. Although this process is highly time-consuming and labor-intensive, most output of this process is not well transformed into machine-readable format. The limited availability of data has largely constrained the artificial intelligence (AI) system development to facilitate this literature reviewing in the regulatory process. In the past decade, AI has revolutionized the area of text mining as many deep learning approaches have been developed to search, annotate, and classify relevant documents. After the great advancement of AI algorithms, a lack of high-quality data instead of the algorithms has recently become the bottleneck of AI system development. Herein, we constructed two large benchmark datasets, Chlorine Efficacy dataset (CHE) and Chlorine Safety dataset (CHS), under a regulatory scenario that sought to assess the antiseptic efficacy and toxicity of chlorine. For each dataset, ∼10,000 scientific articles were initially collected, manually reviewed, and their relevance to the review task were labeled. To ensure high data quality, each paper was labeled by a consensus among multiple experienced reviewers. The overall relevance rate was 27.21% (2,663 of 9,788) for CHE and 7.50% (761 of 10,153) for CHS, respectively. Furthermore, the relevant articles were categorized into five subgroups based on the focus of their content. Next, we developed an attention-based classification language model using these two datasets. The proposed classification model yielded 0.857 and 0.908 of Area Under the Curve (AUC) for CHE and CHS dataset, respectively. This performance was significantly better than permutation test (p < 10E-9), demonstrating that the labeling processes were valid. To conclude, our datasets can be used as benchmark to develop AI systems, which can further facilitate the literature review process in regulatory science.

RESUMO

OBJECTIVE: Adults <30 years' of age experience elevated HIV-rates in Ukraine. Young adults (YA) involved in the criminal justice system (CJS) are at an increased HIV-risk given elevated rates of substance use, engagement in high-risk sexual behaviour and insufficient healthcare access. The objective of this exploratory study was to investigate the acceptability of strategies to refer and link CJS-involved YA to HIV-prevention and substance use treatment services from CJS settings. DESIGN: We conducted qualitative individual interviews with CJS-involved YA (18-24 years), and CJS stakeholders. Interviews were guided by the Social Ecological Model. Interviews with YA explored substance use and sexual behaviour, and acceptability of strategies to link YA to HIV-prevention and substance use treatment services from CJS. Stakeholder interviews explored system practices addressing HIV-prevention and substance use and addiction. Data were analysed using Inductive Thematic Analysis. SETTING: Data were collected in three locales, prior to the 2022 Russian-Ukrainian conflict. PARTICIPANTS: Thirty YA and 20 stakeholders. RESULTS: Most YA were men, reported recent injection drug use and were M age=23 years. YA were receptive to linkage to HIV-prevention services from CJS; this was shaped by self-perceived HIV-risk and lack of access to HIV-prevention services. YA were less receptive to being referred to substance use treatment services, citing a lack of self-perceived need and mistrust in treatment efficacy. Stakeholders identified multilevel contextual factors shaping acceptability of HIV-prevention and substance use treatment from CJS (eg, stigma). CONCLUSIONS: Findings should be reviewed as a historical record of the pre-conflict context. In that context, we identified strategies that may have been used to help curtail the transmission of HIV in a population most-at-risk, including CJS-involved YA. This study demonstrates that improving access to substance use treatment and HIV-prevention services via CJS linkage were acceptable if provided in the right conditions (eg, low or no-cost, confidential).

RESUMO

The Dominican Republic (DR) has the second-highest prevalence of HIV infection in the Caribbean, but viral suppression and treatment adherence are not well understood. We conducted a cross-sectional study among people living with HIV/AIDS(PLWHA) to fill in the knowledge gap. Questionnaire was used to collect demographic data, antiretroviral therapy (ART) adherence, and barriers and facilitators to HIV care. Viral load and other clinical information were extracted through chart reviews. Descriptive analyzes and logistic regression were conducted to explore factors associated with non-viral suppression and imperfect ART adherence. Of 193 PLWHA 83.9% were virally suppressed. Those that were non-virally suppressed were more likely of being male (odds ratio [OR]: 2.55, 95% confidence interval [CI]: 1.17-5.58) and less likely of being unemployed (OR: 0.28, 95% CI: 0.08-0.96). However, being male (OR: 0.78, 95% CI:0.40-1.53) and unemployed (OR: 0.28, 95% CI:0. 08-1.21) were less likely to report imperfect adherence. Tailored interventions are needed to improve adherence and viral suppression in DR.

RESUMO

Cerebral amyloid angiopathy or CAA is a type of vascular dementia that can cause neuroinflammation, ischemia and hemorrhage, among other complications. CAA results from the deposition of amyloid beta (Aß) in blood vessels and is frequently observed in individuals with Alzheimer's disease (AD). One functional output of those pathological changes is measurable cognitive decline. Still not well understood, however, is the impact of gender or sex on the pathology of CAA, as well as CAA-induced cognitive decline. Here, we studied how sex impacts deposition of CAA-related pathology and the associated cognitive decline. We observed differential hippocampal pathology as far as regions of deposition, type of morphology, and total amount of pathology when assessing CAA pathology via (E,E)-1-fluoro-2,5-bis-(3-hydroxycarbonyl-4-hydroxy)styrylbenzene (FSB)-labeling, as well as neurodegeneration via Fluoro Jade C (FJC)-labeling, and lysosomal associated membrane protein deposition via LAMP-1 labeling. In accordance with other studies, our data suggest female TG-SwDI mice exhibit more severe pathological alterations in CAA pathology. Additionally, behavioral assessments revealed an impact of genotype that was more pronounced in TG-SwDI females. While the primary measure of learning and memory, the water maze, suggests an overall effect of genotype, effects in measures of locomotor activity and anxiety-like behavior suggest reduced habituation in females. This could be due to a lower retention for the tasks. Results of this study offer significant insight into the importance of examining effects of sex on CAA.

RESUMO

Police abuse affects people who inject drugs (PWID), including those with HIV, and negatively impacts care engagement. This cross-sectional study evaluated police abuse among PWID receiving MOUD (medication for opioid use disorder) living with HIV and associations with HIV treatment adherence and receipt of NGO services. We assessed lifetime and past six-month rates of police abuse among a cohort of Ukrainian PWID with HIV receiving MOUD (n = 190) from August to September 2017. Logistic regression models evaluated associations between past six-month police abuse and past 30-day antiretroviral therapy (ART) adherence, and past six-month NGO service receipt. Almost all (90%) participants reported lifetime police abuse: 77% reported physical violence and 75% reported paying the police to avoid arrest. One in four females (25%) reported police-perpetrated sexual violence. Recent police abuse was reported by 16% of males and 2% of females and was not associated with ART adherence (aOR: 1.1; 95% CI:0.3-5.0) or NGO service receipt (aOR: 3.4; 95% CI:0.6-18.3). While lifetime police abuse rates were high, few participants reported recent police abuse, which was not linked to care engagement. These trends should encourage the Ukrainian government for public health-public safety partnerships and legal interventions to eliminate human rights violations against PWID living with HIV.

RESUMO

Exposure to relatively high levels of inorganic arsenic (iAs) is associated with detrimental effects on human health, including cancer and diabetes. The effects of lower-level exposures are less clear, and gaps in the literature exist as to the effects of iAs exposure on neurodevelopment. The current study assessed the effects of perinatal iAs exposure on rodent neurodevelopment and behavior. Pregnant Sprague-Dawley (SD) rats were exposed to arsenite (AsIII) via oral gavage on gestational days (GD) 6 through 21, and pups were directly dosed via gavage on postnatal days (PND) 1 through 21. Dams and offspring received the same doses: 0.00, 0.10, 1.50, or 3.75 mg/kg/day. Male and female offspring underwent a battery of behavioral assessments from weaning until PND 180. Brain arsenic levels increased in a dose-dependent manner at both PND 1 and 21. Results from the behavioral tests show that pre- and postnatal AsIII exposure did not adversely affect offspring weight gain, adolescent motor and cognitive functions, or adult motor and cognitive functions in the SD rat. There were no differences in concentration of several brain proteins associated with blood-brain barrier permeability, dopamine functions, and inflammation.

RESUMO

BACKGROUND: Mixed quantitative and qualitative research methods may be useful for characterizing the experiences of patients with post-treatment Lyme disease syndrome. METHODS: 15 participants completed demographic and screening questions, surveys assessing quality of life, fatigue, pain, cognitive functioning, and other patient- reported outcomes, a semi-structured in-depth interview, and consented to a Lyme-related medical chart review. RESULTS: Participants reported mild to moderate symptoms and functional impairments on patient-reported outcome surveys and in-depth interviews. Participants reported on a number of management strategies that they found more or less effective in managing their symptoms. Participants endorsed the need for better clinical assessment of symptom patterns over time, greater Lyme-related education for providers, more holistic approaches to diagnosis and care, and the desire to participate in Lyme-focused support groups. CONCLUSIONS: Overall, participants desired a more holistic approach to diagnosis, symptom assessment, and symptom management. Recommendations for future research and clinical considerations are discussed.

RESUMO

BACKGROUND: Current hepatitis C virus (HCV) counseling guidelines do not recommend that HCV-infected patients notify their partners or encourage them to get tested. We aimed to assess healthcare professionals' knowledge of and attitudes toward counseling and testing recommendations for HCV-infected patients. METHODS: A 15-question, anonymous survey was designed and distributed via email to a convenience sample of healthcare professionals who work with Brown University or Boston University affiliated hospitals to assess their knowledge of and attitudes toward counseling recommendations for HCV-infected patients. The data was collected electronically and analyzed using descriptive statistical methods. RESULTS: Of the 55 respondents (a 20% response rate), 73% incorrectly believed that, at the time the survey was completed, CDC HCV testing guidelines already recommended partners of HCV-infected patients be tested for HCV infection. Furthermore, 80% of respondents believed recommendations should be revisited to explicitly include that HCV-infected patients encourage their partners to get tested. When counseling patients with HCV, 44% of respondents reported they always ask whether the patient's partners have been tested for HCV and 42% reported they sometimes do. Similarly, 42% reported they always suggest that the HCV-infected patient's partners be tested for HCV. CONCLUSIONS: Our survey shows that healthcare providers believe that HCV-counseling and testing recommendations could be revisited, with specific attention given to the promotion of HCV testing for partners of HCV-infected patients.

RESUMO

BACKGROUND: 10-20% of individuals diagnosed with Lyme disease develop chronic symptoms after antibiotic treatment. METHODS: A convenience sample of adults with self- reported, persistent post-Lyme treatment symptoms seeking treatment at the Lifespan Lyme Disease Center in Rhode Island completed a demographic and medical survey, the Patient Reported Outcomes Measurement Information System (PROMIS)-29 v2.0, and other short-form PROMIS measures of cognitive function, sleep disturbance, and fatigue. RESULTS: Compared to average standardized scale scores (T=50; SD=10), participants had mild impairments in physical (T=41) and social (T=42) functioning, mild symptoms of depression (T=56), anxiety (T=60), and sleep disturbance (T=57), and moderate pain interference (T=62), and fatigue (T=65). Participants reported greater symptoms than some other clinical samples including those with cancer and chronic pain. Post-hoc analyses revealed that women reported higher levels of fatigue than men. CONCLUSIONS: People with persistent post-Lyme treatment symptoms report debilitating symptoms and functional impairments which must be considered in clinical care.

RESUMO

Many people undergo procedures requiring general anesthesia each day and adverse cognitive effects have been reported in response to that anesthesia. Postoperative Cognitive Dysfunction (POCD) may occur in as many as 80% of adults during the first post-surgical week and can have lasting effects. Here, the cognitive and motor effects of sevoflurane exposure in Sprague-Dawley rats was examined along with body weights, blood oxygen saturation, heart rate, and body temperature. Male and female rats were exposed to 2.5% sevoflurane or medical grade air for one hour at postnatal day 115. Beginning the following day, rats began a series of behavioral tests examining locomotor activity, motor coordination, novel object recognition, and spatial learning and memory in a water maze. Blood oxygen saturation, heart rate, and body temperature were not affected by the sevoflurane exposure. A slight effect on locomotor activity was detected, but no effects on motor coordination, novel object recognition, or spatial learning and memory were observed. Brain weights following behavioral testing did not differ. The results reported here along with existing literature suggest sevoflurane is largely without effects on later cognition in adult rodents when exposure is of a relatively short duration and at a relatively low concentration.

RESUMO

Violence experience has been consistently associated with HIV risks and substance use behaviors. Although many studies have focused on intimate partner violence (IPV), the role of violence at a structural level (i.e., police abuse) remains relevant for people who inject drugs. This study evaluated the association of IPV and police-perpetrated violence experiences with HIV risk behaviors and substance use in a cohort of HIV-positive people who inject drugs in Ukraine. We also evaluated possible moderation effects of gender and socioeconomic status in the links between violence exposure and HIV risk and polysubstance use behaviors. Data came from the Providence/Boston-CFAR-Ukraine Study involving 191 HIV-positive people who inject drugs conducted at seven addiction treatment facilities in Ukraine. Results from logistic regressions suggest that people who inject drugs and experienced IPV had higher odds of polysubstance use than those who did not experience IPV. Verbal violence and sexual violence perpetrated by police were associated with increased odds of inconsistent condom use. The odds of engaging in polysubstance use were lower for women in relation to police physical abuse. We found no evidence supporting socioeconomic status moderations. Violence experiences were associated with substance use and sexual HIV risk behaviors in this cohort of HIV-positive people who inject drugs in Ukraine. Trauma-informed prevention approaches that consider both individual and structural violence could improve this population's HIV risks.


RESUMEN: La experiencia de violencia se ha asociado sistemáticamente con las conductas de riesgo para la adquisición o transmisión del VIH y con el uso de sustancias. Aunque muchos estudios se han centrado en la violencia infligida por la pareja íntima (VPI), el papel de la violencia estructural (es decir, el abuso policial) sigue siendo relevante para las personas que se inyectan drogas. Este estudio evaluó la asociación entre las experiencias de violencia perpetrada por la policía y la pareja íntima con los conductas de riesgo para la adquisición o transmisión del VIH y el uso de sustancias en una cohorte de personas VIH positivas que se inyectan drogas en Ucrania. También evaluamos los posibles efectos de moderación del género y el estatus socioeconómico entre la exposición a la violencia y los comportamientos de riesgo para la transmisión del VIH y uso de múltiples sustancias. Los datos provienen del estudio Providence / Boston-CFAR-Ucrania en el que participaron 191 personas infectadas por el VIH que se inyectan drogas, realizado en siete centros de tratamiento de adicciones en Ucrania. Los resultados de las regresiones logísticas sugieren que, en comparación con las personas que se inyectan drogas que no experimentaron IPV, las que experimentaron IPV tenían mayor probabilidad de uso de múltiples sustancias. La violencia sexual perpetrada por la policía se asoció con mayores probabilidades de un uso inconsistente del condón. No encontramos evidencia que apoye las moderaciones de género o estatus socioeconómico. Las experiencias de violencia se asociaron con el uso de sustancias y las conductas sexuales de riesgo para la transmisión del VIH en esta cohorte de personas VIH positivas que se inyectan drogas en Ucrania. Los enfoques de prevención basados en las experiencias traumáticas que tienen en cuenta tanto la violencia individual como la estructural podrían mejorar las conductas de riesgo para la transmission del VIH de esta población.

RESUMO

The coronavirus disease 2019 (COVID-19) pandemic is a rapidly evolving global emergency that continues to strain healthcare systems. Emerging research describes a plethora of patient factors-including demographic, clinical, immunologic, hematological, biochemical, and radiographic findings-that may be of utility to clinicians to predict COVID-19 severity and mortality. We present a synthesis of the current literature pertaining to factors predictive of COVID-19 clinical course and outcomes. Findings associated with increased disease severity and/or mortality include age > 55 years, multiple pre-existing comorbidities, hypoxia, specific computed tomography findings indicative of extensive lung involvement, diverse laboratory test abnormalities, and biomarkers of end-organ dysfunction. Hypothesis-driven research is critical to identify the key evidence-based prognostic factors that will inform the design of intervention studies to improve the outcomes of patients with COVID-19 and to appropriately allocate scarce resources.

RESUMO

Although the prevalence of Lyme and tick-borne diseases (TBDs) continues to rise, there is conflicting information regarding the best approach to management. The Lifespan Lyme Disease Clinic (LDC) is an academic out- patient clinic for Lyme and other TBDs. A chart review of 218 new patients between March and November 2018 was conducted. Symptoms most commonly reported included fatigue (66.5%), joint pain (58.2%), cognitive difficulty (32.1%), and headaches (27.9%). Most (87.1%) patients had received TBD-directed antibiotic treatment prior to their first appointment. Of the 136 patients who had experienced more than 6 months of symptoms attributed to Lyme, 55.1% had positive two-tiered serologies. Many patients characterized themselves as having "chronic Lyme" or had a diagnosis of "post-treatment Lyme disease syndrome," a condition for which there is no clear consensus on pathophysiology or treatment. Outlined here are some lessons learned and practical approaches used by LDC physicians in caring for this patient population.

RESUMO

BACKGROUND: The US Food and Drug Administration issued an Emergency Use Authorization for remdesivir use in patients with severe COVID-19. METHODS: We utilized data from 2 quaternary acute care hospitals. The outcomes of interest were the impact of remdesivir on in-hospital death by day 28 and time to recovery, clinical improvement, and discharge. We utilized Cox proportional hazards models and stratified log-rank tests. RESULTS: Two hundred twenty-four patients were included in the study. The median age was 59 years; 67.0% were male; 17/125 patients (13.6%) who received supportive care and 7/99 patients (7.1%) who received remdesivir died. The unadjusted risk for 28-day in-hospital death was lower for patients who received remdesivir compared with patients who received supportive care (hazard ratio [HR], 0.42; 95% CI, 0.16-1.08). Although this trend remained the same after adjusting for age, sex, race, and oxygen requirements on admission (adjusted HR [aHR], 0.49; 95% CI, 0.19-1.28), as well as chronic comorbidities and use of corticosteroids (aHR, 0.44; 95% CI, 0.16-1.23), it did not reach statistical significance. The use of remdesivir was not associated with an increased risk of acute kidney injury (AKI) or liver test abnormalities. Although not statistically significant, the rate ratios for time to recovery, clinical improvement, and discharge were higher in women and black or African American patients. CONCLUSIONS: Patients on remdesivir had lower, albeit not significant, all-cause in-hospital mortality, and the use of remdesivir did not increase the risk for AKI. Promising signals from this study need to be confirmed by future placebo-controlled randomized clinical trials.

RESUMO

INTRODUCTION: Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has infected >6 million people worldwide since December 2019. Global reports of HIV/SARS-CoV-2 coinfection are limited. To better understand the impact of the coronavirus disease 2019 (COVID-19) pandemic on persons with HIV and improve their care, we present an outpatient and inpatient clinical experience of HIV/SARS-CoV-2 coinfection from Rhode Island, US. METHODS: We describe outpatient and inpatient preparedness for the COVID-19 pandemic, and present a case series of all known patients with HIV/SARS-CoV-2 coinfection at The Miriam Hospital and Rhode Island Hospital, and The Miriam Hospital Infectious Diseases and Immunology Center, in Providence, Rhode Island, US. RESULTS AND DISCUSSION: The Infectious Diseases and Immunology Center rapidly prepared for outpatient and inpatient care of persons with HIV and SARS-CoV-2. Between 30 March and 20 May 2020, 27 patients with HIV were diagnosed with SARS-CoV-2. Twenty were male, six female and one transgender female; average age was 49 years; 13/27 were Hispanic and 6/27 were African American. All had HIV viral load <200 copies/mL and were on antiretroviral therapy with CD4 count range 87 to 1441 cells/µL. Twenty-six of the 27 had common COVID-19 symptoms for one to twenty-eight days and most had other co-morbidities and/or risk factors. Nine of the 27 were hospitalized for one to thirteen days; of those, three lived in a nursing home, six received remdesivir through a clinical trial or emergency use authorization and tolerated it well; eight recovered and one died. Overall, 17% of known Center people had HIV/SARS-CoV-2 coinfection, whereas the comparable state-wide prevalence was 9%. CONCLUSIONS: We highlight challenges of outpatient and inpatient HIV care in the setting of the COVID-19 pandemic and present the largest detailed case series to date from the United States on HIV/SARS-CoV-2 coinfection, adding to limited global reports. The aggregated clinical findings suggest that the clinical presentation and outcomes of COVID-19 appear consistent with those without HIV. Whether SARS-CoV-2 infection is more frequent among persons with HIV remains to be determined. More data are needed as we develop our understanding of how HIV and antiretroviral therapy are affected by or have an impact on this pandemic.

RESUMO

BACKGROUND: Dexamethasone, a synthetic glucocorticoid, has anti-inflammatory and immunosuppressive properties. There is a hyperinflammatory response involved in the clinical course of patients with pneumonia due to SARS-CoV-2. To date, there has been no definite therapy for COVID-19. We reviewed the charts of SARS-CoV-2 patients with pneumonia and moderate to severely elevated CRP and worsening hypoxemia who were treated with early, short-term dexamethasone. METHODS: We describe a series of 21 patients who tested positive for SARS-CoV-2 and were admitted to The Miriam Hospital in Providence, RI, and were treated with a short course of dexamethasone, either alone or in addition to current investigative therapies. RESULTS: CRP levels decreased significantly following the start of dexamethasone from mean initial levels of 129.52 to 40.73 mg/L at time of discharge. 71% percent of the patients were discharged home with a mean length of stay of 7.8 days. None of the patients had escalation of care, leading to mechanical ventilation. Two patients were transferred to inpatient hospice facilities on account of persistent hypoxemia, in line with their documented goals of care. CONCLUSIONS: A short course of systemic corticosteroids among inpatients with SARS-CoV-2 with hypoxic respiratory failure was well tolerated, and most patients had improved outcomes. This limited case series may not offer concrete evidence towards the benefit of corticosteroids in COVID-19. However, patients' positive response to short-term corticosteroids demonstrates that they may help blunt the severity of inflammation and prevent a severe hyperinflammatory phase, in turn reducing the length of stay, ICU admissions, and healthcare costs.

RESUMO

INTRODUCTION: Co-located treatment for HIV and opioid use disorder has been shown to improve care outcomes for HIV-positive people who inject drugs (PWID) in Ukraine. However, patients continue to be stigmatized for both HIV and substance use. This study aimed to assess whether co-located care for HIV-positive PWID receiving opioid agonist treatment (OAT) services in Ukraine is associated with less stigma and better perceived quality of HIV services. METHODS: This cross-sectional study enrolled 191 HIV-positive PWID who received OAT services at three healthcare facilities providing substance use treatment (OAT only) and at four facilities that provided co-located care (both OAT and HIV treatment) in six regions in Ukraine during July-September, 2017. Primary outcomes were HIV stigma (Berger scale), substance use stigma (Substance Abuse Stigma Scale) and intersectional stigma (both stigma forms above 75th percentile). Secondary outcome was quality of HIV care, a composite score based on a package of received services. Linear and ordinal regressions were used to assess the predictors of selected outcomes. RESULTS: Study participants were 75% male, mean age 40 ± 7 years; 47% received co-located care, and 10.5% had both high HIV and substance use stigma. Co-located care was neither associated with HIV nor substance use stigma but it was linked to better quality of HIV care (adjusted odds ratio: 4.13; 95% CI: 2.31, 7.54). HIV stigma was associated with suicide attempts (adjusted beta (aß): 5.90; 95% CI: 2.05, 9.75), and substance use stigma was linked to poor mental health (aß: -0.26; 95% CI: -0.44, -0.08) and lower likelihood of receipt of services from non-governmental organization (NGO; aß: -6.40; 95% CI: -10.23, -2.57). CONCLUSION: One in ten people with HIV in this cohort who received OAT services experienced high levels of both HIV and substance use stigma, which was associated with poorer mental health and less NGO support. Co-located HIV and OAT services were linked to better perceived quality of HIV care, but did not seem to reduce stigma for this key population. Stigma interventions for PWID, possibly delivered involving NGOs, may be an approach to mitigate this challenge.

RESUMO

Between October 2015 and March 2018, we conducted the Modified Antiretroviral Treatment Access Study (MARTAS), a nurse-delivered case management intervention to improve linkage-to-care for persons recently tested HIV positive. Adult participants from nine urban clinics in three regions of Ukraine were randomized to either MARTAS or standard of care (SOC) using individual, parallel, two-arm design. The main study outcome was linkage-to-care (defined as registration at an HIV clinic) within a 3-month period from enrollment in the study. Intention-to-treat analysis of MARTAS (n = 135) versus SOC (n = 139) showed intervention efficacy in linkage to HIV care (84.4% vs. 33.8%; adjusted RR 2.45; 95% CI 1.72, 3.47; p < 0.001). MARTAS is recommended for implementation in Ukraine and may be helpful in other countries with similar gaps in linkage-to-care. Clinicaltrials.gov registration number: NCT02338024.
