RESUMO
BACKGROUND: Substance use is common among people living with human immunodeficiency virus (PLWH) and a barrier to achieving viral suppression. Among PLWH who report illicit drug use, we evaluated associations between HIV viral load (VL) and reduced use of illicit opioids, methamphetamine/crystal, cocaine/crack, and marijuana, regardless of whether or not abstinence was achieved. METHODS: This was a longitudinal cohort study of PLWH from 7 HIV clinics or 4 clinical studies. We used joint longitudinal and survival models to examine the impact of decreasing drug use and of abstinence for each drug on viral suppression. We repeated analyses using linear mixed models to examine associations between change in frequency of drug use and VL. RESULTS: The number of PLWH who were using each drug at baseline ranged from n = 568 (illicit opioids) to n = 4272 (marijuana). Abstinence was associated with higher odds of viral suppression (odds ratio [OR], 1.4-2.2) and lower relative VL (ranging from 21% to 42% by drug) for all 4 drug categories. Reducing frequency of illicit opioid or methamphetamine/crystal use without abstinence was associated with VL suppression (OR, 2.2, 1.6, respectively). Reducing frequency of illicit opioid or methamphetamine/crystal use without abstinence was associated with lower relative VL (47%, 38%, respectively). CONCLUSIONS: Abstinence was associated with viral suppression. In addition, reducing use of illicit opioids or methamphetamine/crystal, even without abstinence, was also associated with viral suppression. Our findings highlight the impact of reducing substance use, even when abstinence is not achieved, and the potential benefits of medications, behavioral interventions, and harm-reduction interventions.

BACKGROUND: Sepsis is the leading cause of in-hospital death. The SEP-1 sepsis bundle is a protocol for early sepsis care that requires providers to diagnose and treat sepsis quickly. Limited evidence suggests that adherence to the sepsis bundle is lower in cases of hospital-onset sepsis. OBJECTIVE: To compare sepsis bundle adherence in hospital-onset vs. community-onset sepsis. DESIGN: Retrospective cohort study using multivariable analysis of clinical data. PARTICIPANTS: A total of 4658 inpatients age 18 or older were identified by diagnosis codes consistent with sepsis or disseminated infection. SETTING: Four university hospitals in California between 2014 and 2016. MAIN OUTCOMES AND MEASURES: The primary outcome was adherence to key components of the sepsis bundle defined by the Centers for Medicare and Medicaid Services in their core measure, SEP-1. Covariates included clinical characteristics related to the patient, infection, and pathogen. KEY RESULTS: Compared with community-onset, cases of hospital-onset sepsis were less likely to receive SEP-1 adherent care (relative risk 0.33, 95% confidence interval 0.29-0.38, p < 0.001). With the exception of vasopressors (RR 1.11, p = 0.002), each component of SEP-1 evaluated-blood cultures (RR 0.76, p < 0.001), serum lactate (RR 0.51, p < 0001), broad-spectrum antibiotics (RR 0.62, p < 0.001), intravenous fluids (0.47, p < 0.001), and follow-up lactate (RR 0.71, p < 0.001)-was less likely to be performed within the recommended time frame in hospital-onset sepsis. Within the hospital, cases of hospital-onset sepsis arising on the ward were less likely to receive SEP-1-adherent care than were cases arising in the intensive care unit (RR 0.68, p = 0.004). CONCLUSIONS: Inpatients with hospital-onset sepsis receive different management than individuals with community-onset sepsis. It remains to be determined whether system-level factors, provider-level factors, or factors related to measurement explain the observed variation in care or whether variation in care affects outcomes.

Life chaos, the perceived inability to plan for and anticipate the future, may be a barrier to the HIV care continuum for people living with HIV who experience incarceration. Between December 2012 and June 2015, we interviewed 356 adult cisgender men and transgender women living with HIV in Los Angeles County Jail. We assessed life chaos using the Confusion, Hubbub, and Order Scale (CHAOS) and conducted regression analyses to estimate the association between life chaos and care continuum. Forty-eight percent were diagnosed with HIV while incarcerated, 14% were engaged in care 12 months prior to incarceration, mean antiretroviral adherence was 65%, and 68% were virologically suppressed. Adjusting for sociodemographics, HIV-related stigma, and social support, higher life chaos was associated with greater likelihood of diagnosis while incarcerated, lower likelihood of engagement in care, and lower adherence. There was no statistically significant association between life chaos and virologic suppression. Identifying life chaos in criminal-justice involved populations and intervening on it may improve continuum outcomes.

BACKGROUND: Self-reported antiretroviral therapy (ART) adherence measures that are associated with plasma viral load (VL) are valuable to clinicians and researchers, but are rarely examined among groups vulnerable to dropping out of care. One-seventh of all those living with HIV pass through incarceration annually and criminal-justice (CJ) involved people living with HIV (PLH) are vulnerable to falling out of care. We examined the association of self-reported ART adherence with VL in a criminal-justice sample compared to a routine-care sample. METHODS: Samples: We examined data from a multisite collaboration of studies addressing the continuum of HIV care among CjJ involved persons in the Seek, Test, Treat, and Retain cohort. Data pooled from seven CJ- studies (n = 414) were examined and compared with the routine-care sample from the Centers for AIDS Research Network of Integrated Clinical Systems' seven sites (n = 11,698). MEASURES: In both samples, data on self-reported percent ART doses taken were collected via the visual analogue scale adherence measure. Viral load data were obtained by blood-draw. ANALYSIS: We examined the associations of adherence with VL in both cohorts using mixed effects linear regression of log-VL, and mixed effects logistic regression of binary VL (≥ 200 copies/mL) outcomes. Interactions by CD4 count and self-reported health status were also tested. RESULTS: Among the CJ sample, the coefficient for log-VL was - 0.31 (95% CI = - 0.43, - 0.18; P < 0.01) and that in the routine-care sample was - 0.42 (95% CI = - 0.45, - 0.38; P < 0.01). For the logistic regression of binary detectable VL on 10% increments of adherence we found the coefficient was - 0.26 (95% CI = - 0.37, - 0.14; P < 0.01) and in the routine-care sample it was - 0.38 (95% CI = - 0.41, - 0.35; P < 0.01). There was no significant interaction by CD4 count level in the CJ sample, but there was in the routine-care sample. Conversely, there was a significant interaction by self-reported health status level in the criminal-justice sample, but not in the routine-care sample. CONCLUSIONS: The visual analogue scale is valid and useful to measure ART adherence, supporting treatment for CJ- involved PLH vulnerable to falling out of care. Research should examine adherence and VL in additional populations.

OBJECTIVE: To develop and evaluate psychometrically a self-reported instrument assessing physical fatigability (PF) and mental fatigability (MF) in adults with spinal cord injury (SCI). DESIGN: Cross-sectional. SETTING: Peer-support groups at rehabilitation centers, online support groups. PARTICIPANTS: Adults with SCI (N=464) in the United States. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The dimensional structure was assessed by confirmatory factor analysis. The relationship between item responses and fatigability was measured with item response theory (graded response model). Reliability was measured with test information functions. Differential item functioning was evaluated with Wald chi-square tests and the weighted area between the curves. Construct validity was assessed using the known groups method. RESULTS: An 82-item pool was developed from prior qualitative research and consultations with rehabilitation experts. A non-probability sample (N=464) was used to evaluate the psychometric properties of the PF and MF scales. The item pool was reduced to 75 based on factor loadings and R2. Both scales are primarily unidimensional, despite moderate multidimensionality. There is good discrimination overall: 18 PF items and 26 MF items have high or very high discrimination power (slopes > 1.35). The measurement precision in the theta range -2.0 to 2.5 is the equivalent of 0.94 reliability for PF and 0.91 for MF. For both measures, F statistics P values were significant at P<.01, and means were higher for those with paraplegia vs quadriplegia, and for those with incomplete paraplegia. CONCLUSIONS: The Fatigability Index is the first instrument designed to assess physical and mental fatigability in adults with SCI. The index highlights causes of fatigue and areas requiring immediate intervention. Development of short-forms and further research on representative samples are necessary.

BACKGROUND: Illicit drug use (DU) and hazardous drinking (HD) among marginalized populations may be associated with greater barriers to care. METHODS: We used baseline data on the participants of the Seek, Test, Treat, and Retain data harmonization initiative. DU includes use of any illicit drugs within the past 6 months. HD was defined as scores ≥8 for men and ≥ 7 for women on Alcohol Use Disorders Identification Test within the past 12 months. Social support scores were assigned by summing scores from individual questions related to social support. Two outcomes for multivariable regression models and mediation analysis were perceived access to care and perceived barriers to care scores, calculated from summated points from individual questions within each domain. All models were adjusted for age, gender, race/ethnicity, and social support and stratified by HIV status. RESULTS: Among 1403 illicit drug users and 4984 non-drug users, the mean age was 39.6 ± 12.2 years old, 71% were male, 57% African Americans, and 39% Hispanic/Latinos. Over 25% reported difficulties in covering medical costs and finding transportation to health care facilities and greater proportions of drug users and hazardous drinkers reported these issues than non-DU/non-HD. In multivariable models, DU and HD were both independently associated with having greater barriers to care (ß: 0.49 (95% confidence interval: 0.19 to 0.79) p < 0.01; 0.31 (0.18 to 0.45) < 0.01) in HIV-negative participants. Neither DU nor HD was strongly associated with barriers to care for HIV-positive participants. Social support was associated with better perceived access to care and fewer barriers to care in the HIV-negative participants. CONCLUSION: The current study found that financial burdens of care, logistical difficulties in accessing care, and low social support were common challenges among individuals using illicit drugs and/or drinking hazardously. Addressing structural barriers and strengthening social support may be important strategies to improve health care among marginalized populations, regardless of HIV status.

Public Health Critical Race Praxis (PHCRP) contributes three functional elements to health equity studies: a race conscious orientation; an antiracism lexicon based on Critical Race Theory (CRT); and an integrated, reflexive approach. Few big data studies employ all three functional elements. Therefore, this article describes the application of PHCRP to the Human Immunodeficiency Virus Testing, Linkage and Retention in care (HIV TLR) study (N=3,476,741), which connects multiple large datasets to electronic medical records to examine contextual determinants of racial/ethnic disparities in HIV care continuum outcomes in southern California. As HIV TLR demonstrates, PHCRP's innovative tools and strategies help big data research maintain fidelity to CRT.

BACKGROUND: Evidence-based HIV treatment adherence interventions have typically shown medium-sized effects on adherence. Prior evidence-based HIV treatment adherence interventions have not been culturally adapted specifically for Black/African Americans, the population most affected by HIV disparities in the USA, who exhibit lower adherence than do members of other racial/ethnic groups. PURPOSE: We conducted a randomized controlled trial of Rise, a 6-month culturally congruent adherence counseling intervention for HIV-positive Black men and women. METHODS: Rise was delivered by a trained peer counselor who used a problem-solving approach to address culturally congruent adherence barriers (e.g., medical mistrust, HIV stigma) and assisted with linkage to supportive services. A total of 215 participants were randomized to the intervention group (n = 107) or a wait-list control group (n = 108). Adherence was assessed daily via electronic monitoring. RESULTS: In a repeated measures multivariate logistic regression model of dichotomous adherence (using a clinically significant cutoff of 85% of doses taken), adjusted for sociodemographic and medical covariates, adherence in the intervention group improved over time relative to the control group, (OR = 1.30 per month (95% CI = 1.12-1.51), p < 0.001), representing a large cumulative effect after 6 months (OR = 4.76, Cohen's d = 0.86). CONCLUSIONS: Rise showed a larger effect on adherence than prior HIV adherence intervention studies. For greater effectiveness, interventions to improve adherence among Black people living with HIV may need to be customized to address culturally relevant barriers to adherence.

In the United States, little is known about interventions that rely on mobile phones and/or text messaging to improve engagement in HIV care for vulnerable populations. Domestic studies using these technologies as part of the National Institute on Drug Abuse "Seek, Test, Treat, Retain" research initiative were queried regarding intervention components, implementation issues, participant characteristics, and descriptive statistics of mobile phone service delivery. Across five studies with 1,135 predominantly male, minority participants, implementation challenges occurred in three categories: (1) service interruptions; (2) billing/overage issues, and; (3) the participant user experience. Response rules for automated text messages frequently frustrated participants. The inability to reload minutes/texting capacity remotely was a significant barrier to intervention delivery. No study encountered confidentiality breaches. Service interruption was common, even if studies provided mobile phones and plans. Future studies should attend to the type of mobile phone and service, the participant user experience, and human subjects concerns.

The U.S. female criminal justice (CJ) population is rapidly growing, yet large-scale studies exploring gender-specific HIV risk behaviors in the CJ population are lacking. This analysis uses baseline data on adults with a CJ history from eight U.S. studies in an NIH-funded "Seek, Test, Treat, Retain" harmonization consortium. Data were collected using a standardized HIV risk behavior assessment tool and pooled across studies to describe participants' characteristics and risk behaviors. Multilevel mixed-effects logistic regression models were used to test for gender-based behavior differences. Among 784 HIV-positive (21.4% female) and 5521 HIV-negative (8.5% female) participants, HIV-positive women had higher odds than HIV-positive men of engaging in condomless sexual intercourse (AOR 1.84 [1.16-2.95]) with potentially sero-discordant partners (AOR 2.40 [1.41-4.09]) and of sharing injection equipment (AOR 3.36 [1.31-8.63]). HIV risk reduction interventions targeting CJ-involved women with HIV are urgently needed as this population may represent an under-recognized potential source of HIV transmission.

PURPOSE: To identify which aspects of life are most important to adults with spinal cord injury (SCI) and compare perspectives in the United States and the United Kingdom. METHODS: We conducted 20 in-depth interviews with adults with SCI (ten in the US and ten in the UK). Verbatim transcriptions were independently analyzed line-by-line by two coders using an inductive approach. Codes were grouped into themes about factors that constitute and affect quality of life (QOL). RESULTS: Five overarching themes emerged: describing QOL in the context of SCI; functional adjustment; medical care; financial resources; and socio-political issues. Twenty subthemes emerged on factors that affect QOL. Participants in both samples identified medical care as a key influence on QOL. The US group talked about a predominantly negative influence (e.g., fragmented primary and specialist care, insurance constraints, bureaucracy), whereas UK interviewees mentioned a predominantly positive influence (e.g., universal provision, including free and continuous care, free wheelchairs and home care, and length of rehabilitation commensurate with level of injury). Functional adjustment, such as physical and mental adjustment post-discharge and aging with SCI, was another important contributor to QOL, and varied by country. Most US interviewees reported poor knowledge about self-care post-discharge and poor quality of home adaptations compared to the UK group. CONCLUSIONS: For adults living with SCI, good QOL is essential for successful rehabilitation. Differences between interviewees from the two countries in perceived medical care and functional adjustment suggest that factors affecting QOL may relate to broader health system characteristics.

HIV/AIDS-related stigma is a key factor impeding patient utilization of HIV testing services. To destigmatize HIV testing, the Centers for Disease Control and Prevention recommended an 'opt-out' screening strategy aimed at all patients in all clinical settings, regardless of HIV risk. This study assessed whether opt-out screening as compared to opt-in screening was associated with increased uptake of HIV testing among patients with HIV/AIDS-related stigma concerns. This study included 374 patients attending two Los Angeles ambulatory care clinics. Stigma items were grouped into three constructs: Blame/isolation, abandonment, and contagion. Individuals endorsing the blame/isolation subscale (AOR = 0.52; 95 % CI 0.29-0.92; p\0.05) and abandonment subscale (AOR = 0.27; 95 % CI 0.13-0.59; p\0.01) were significantly less likely to accept an HIV test. Additionally, the opt-out model did not counter the negative effects of stigma on HIV test acceptance. These findings indicate that stigma remains a barrier to HIV testing, regardless of the opt-out screening approach.

Fear of violent crime is common among adolescents in urban settings; however, little is known about individual- and neighborhood-level determinants of fear. A generalized ordered logit model was used to analyze individual- and neighborhood-level variables among 2474 adolescents. Seeing violence significantly reduced the probability of feeling unafraid, as did higher levels of social disorder. The more block faces where police were visible, the higher the probability of feeling unafraid and lower the probability of feeling very afraid. Reducing fear could affect more people than just reducing crime. Fear-reduction strategies should target those most at risk of becoming fearful.

The Centers for Disease Control and Prevention recommends routine human immunodeficiency virus (HIV) testing of every client presenting for services in venues where HIV prevalence is high. Because older adults (aged ≥50 years) have particularly poor prognosis if they receive their diagnosis late in the course of HIV disease, any screening provided to younger adults in these venues should also be provided to older adults. We examined aging-related disparities in recent (past 12 months) and ever HIV testing in a probability sample of at-risk adults (N = 1238) seeking services in needle exchange sites, sexually transmitted disease clinics, and Latino community clinics that provide HIV testing. Using multiple logistic regression with generalized estimating equations, we estimated associations between age category (<50 years vs. ≥50 years) and each HIV testing outcome. Even after controlling for covariates such as recent injection drug use, older adults had 40% lower odds than younger adults did of having tested in the past 12 months (odds ratio [OR] = 0.6; 95% confidence interval [CI] = 0.40-0.90) or ever (OR = 0.6; 95% CI = 0.40-0.90). Aging-related disparities in HIV testing exist among clients of these high HIV prevalence venues and may contribute to known aging-related disparities in late diagnosis of HIV infection and poor long-term prognosis.

OBJECTIVE: While gel-formulated rectal microbicides (RM) are the first to enter clinical trials, rectal douching in preparation for anal intercourse is a common practice; thus RMs formulated as douches may be a convenient alternative to gels. Nonetheless, little is known about potential users' thoughts regarding douche-formulated RMs or rectal douching practices, data that is needed to inform the advancement of douche-based RMs. This qualitative study examined thoughts regarding douches, their use as an RM and current douching practices among men who have sex with men and transgender women. METHODS: 12 focus groups and 36 in-depth interviews were conducted (N=140) to examine the overall acceptability of RM, of which one component focused on rectal douching. Focus groups and interviews were recorded, transcribed verbatim and coded; text relating to rectal douching was extracted and analysed. Sociodemographic information was collected using a self-administered questionnaire. RESULTS: Support for a douche-formulated RM centred on the possibility of combined precoital hygiene and HIV protection, and it was believed that a deeply penetrating liquid douche would confer greater HIV protection than a gel. Drawbacks included rectal dryness, impracticality and portability issues, and potential side effects. Non-commercial douching apparatus use was common and liquids used included detergents, vinegar, bleach, lemon juice and alcohol. CONCLUSIONS: A douche-formulated RM, while desirable and perceived as more effective than a gel-formulated RM, also generated questions regarding practicality and side effects. Of immediate concern were the non-commercial liquids already being used that likely damage rectal epithelia, potentially increasing HIV infection risk. Precoital rectal douching is common and an RM formulated as such is desirable, but education on rectal douching practices is needed now.

OBJECTIVES: We examined views on rectal microbicides (RMs), a potential HIV prevention option, among men who have sex with men and transgender women in 3 South American cities. METHODS: During September 2009 to September 2010, we conducted 10 focus groups and 36 in-depth interviews (n = 140) in Lima and Iquitos, Peru, and Guayaquil, Ecuador, to examine 5 RM domains: knowledge, thoughts and opinions about RM as an HIV prevention tool, use, condoms, and social concerns. We coded emergent themes in recorded and transcribed data sets and extracted representative quotes. We collected sociodemographic information with a self-administered questionnaire. RESULTS: RM issues identified included limited knowledge; concerns regarding plausibility, side effects, and efficacy; impact on condom use; target users (insertive vs receptive partners); and access concerns. CONCLUSIONS: Understanding the sociocultural issues affecting RMs is critical to their uptake and should be addressed prior to product launch.

Compulsory vaccination is a frequently implemented policy option for ensuring comprehensive vaccine coverage. Ongoing controversies around human papillomavirus vaccine dissemination, and suboptimal coverage, suggest the value of assessing acceptability of compulsory vaccinations-particularly among likely target populations-in advance of their public availability to support evidence-informed interventions. With the first HIV vaccine to demonstrate partial efficacy in a large-scale clinical trial, we examined individual characteristics and attitudes associated with support for compulsory HIV vaccination policy among a diverse, representative sample of adults attending probable HIV vaccine dissemination venues in a large urban county. Participants were recruited using three-stage probability sampling from likely venues for future HIV vaccine dissemination. We used Audio-CASI to administer a 60-min structured questionnaire. Items included endorsement of compulsory HIV vaccination policy, sociodemographic characteristics, injecting drug use, vaccine attitudes and perceived HIV risk. Among 1,225 participants (mean age = 36.8 years; 55.6 % males, 37.6 % non-English speaking Hispanic, 78.8 % heterosexual, 25.7 % injection drug users), almost half (48.2 %) endorsed a compulsory HIV vaccination policy. Non-English speaking Hispanics compared to whites, participants with less than high school education, higher positive vaccine attitude scores and higher perceived HIV risk were significantly more likely, and people who inject drugs significantly less likely to endorse compulsory HIV vaccination. Public health interventions to promote positive vaccine attitudes and accurate perceptions of HIV risk among vulnerable populations, and strategies tailored for people who inject drugs, may build support for compulsory HIV vaccination policy and promote broad HIV vaccine coverage.

Optimal adherence to antiretroviral therapy (ART) is essential for reducing mortality and morbidity in persons living with HIV/AIDS (PLWHA), as well as for reducing the risk of further HIV transmission. While studies have identified psychosocial factors such as lack of social support and poor mental health status as important barriers to optimal ART adherence, few studies have explored the potential of a mediation effect of psychosocial factors on the relationship between social support and optimal ART adherence. This paper assessed whether mental health status mediated the relationship between social support and optimal ART adherence among a cross-sectional sample of 202 persons living with HIV who were recruited from HIV clinical care sites and community-based organizations in Los Angeles County (LAC). Participants completed a survey that included social support items from the Medical Outcome Study: Social Support Survey (MOS-SSS) Instrument, mental health measures from the Medical Outcomes Study Short Form (SF-12), and ART adherence based on self-report. Among those currently taking ART, 61.7% reported having optimal adherence. Social support was significantly associated with a high score on the mental health status scale (AOR =2.90; 95% CI=1.14-5.78) and optimal ART adherence (AOR=1.81; 95% CI=1.81; 95% CI=1.18-2.79). When mental health status was introduced into the model, the association between social support and optimal ART adherence was no longer significant. Our findings suggest the HIV interventions targeting social support to improve ART adherence will likely be most successful if the support bolsters the mental health of the participants. Clearly, better understanding the relationships among social support, mental health, and ART adherence will be critical for development and implementation of future ART adherence interventions.

Provider-initiated opt-out HIV screening suggests that providers should routinely order HIV tests unless a patient declines. However, data on how providers will respond to this new screening model are scarce. Documented concerns from the providers' perspectives have included time constraints of a typical patient encounter, and discomfort with discussing sexual history and risk behavior with patients. To address these potential barriers, nurse-initiated screening has been proposed as an approach to increasing screening rates in general medical and urgent care settings. This study compares patient acceptability of provider-initiated opt-out HIV screening with nurse-initiated opt-out HIV screening among 220 patients between the ages of 18-64 from two publically funded "safety-net" outpatient clinics in Los Angeles County. Our study found that 77% of patients agreed to HIV testing using opt-out screening, and that HIV test acceptance was higher with the physician-initiated opt-out model compared with the nurse-initiated opt-out model (adjusted odds ratios = 2.92; 95% CI = 1.37-6.22). These findings indicate that adding opt-out screening to primary care providers responsibilities may be an acceptable and effective strategy for addressing the perennially low HIV testing rates, particularly among low income, traditionally underserved patient populations among whom the epidemic is expanding most rapidly.

Conjoint Analysis (CJA), a statistical market-based technique that assesses the value consumers place on product characteristics, may be used to predict acceptability of hypothetical products. Rectal Microbicides (RM)-substances that would prevent HIV infection during receptive anal intercourse-will require acceptability data from potential users in multiple settings to inform the development process by providing valuable information on desirable product characteristics and issues surrounding potential barriers to product use. This study applied CJA to explore the acceptability of eight different hypothetical RM among 128 MSM in Lima and Iquitos, Peru; Guayaquil, Ecuador; and Rio de Janeiro, Brazil. Overall RM acceptability was highest in Guayaquil and lowest in Rio. Product effectiveness had the greatest impact on acceptability in all four cities, but the impact of other product characteristics varied by city. This study demonstrates that MSM from the same region but from different cities place different values on RM characteristics that could impact uptake of an actual RM. Understanding specific consumer preferences is crucial during RM product development, clinical trials and eventual product dissemination.
