Worsening trends in the frequency of methamphetamine and other stimulant use between treatment admission and discharge

BackgroundTreatment for methamphetamine and other stimulants can be effective but treatment attrition and continued use are very high. Abstinence is the conventional outcome used to evaluate treatment success, but defining treatment success in this way misses opportunities to promote improved health even when abstinence is not achieved. Reducing methamphetamine and stimulant use without abstinence is associated with many positive outcomes. However, little is known about drug use patterns during treatment or trends in use over time. MethodsWe used the Treatment Episode Dataset-Discharges (TEDS-D) to identify treatment episodes that had a stimulant drug indicated as the primary substance of use (2017–2021; N=251,841; methamphetamine, cocaine, other amphetamines, or other stimulants). Our outcome was the change in the frequency of drug use between admission and discharge (decreased use with abstinence, decreased use without abstinence, increased use). We used multiple logistic regression to model a change in drug use frequency, predicted by year, stimulant type, and their interaction. ResultsNearly two-thirds of the sample (60 %) had methamphetamine indicated as the primary stimulant of use. There was a decrease in the predicted rate of abstinence over time and worsening trends were strongest among those using methamphetamine. Daily and periodic drug use at both admission and discharge (no change in use) became worse over time, particularly for those using methamphetamine. ConclusionTreatment outcomes worsened over time and declined fastest among those reporting methamphetamine. Abstinence was rare and most treatment clients did not change their drug use behavior. We recommend a renewed focus on evidence-based harm reduction while the nation’s treatment systems continue grappling with the stimulant crises.

Wearable, Biocompatible, and Dual-Emission Ocular Multisensor Patch for Continuous Profiling of Fluoroquinolone Antibiotics in Tears.

The abuse or misuse of antibiotics in clinical and agricultural settings severely endangers human health and ecosystems, which has raised profound concerns for public health worldwide. Trace detection and reliable discrimination of commonly used fluoroquinolone (FQ) antibiotics and their analogues have consequently become urgent to guide the rational use of antibiotic medicines and deliver efficient treatments for associated diseases. Herein, we report a wearable eye patch integrated with a quadruplex nanosensor chip for noninvasive detection and discrimination of primary FQ antibiotics in tears during routine eyedrop treatment. A set of dual-mode fluorescent nanoprobes of red- or green-emitting CdTe quantum dots integrated with lanthanide ions and a sensitizer, adenosine monophosphate, were constructed to provide an enhanced fluorescence up to 45-fold and nanomolar sensitivity toward major FQs owing to the aggregation-regulated antenna effect. The aggregation-driven, CdTe-Ln(III)-based microfluidic sensor chip is highly specific to FQ antibiotics against other non-FQ counterparts or biomolecular interfering species and is able to accurately discriminate nine types of FQ or non-FQ eyedrop suspensions using linear discriminant analysis. The prototyped wearable sensing detector has proven to be biocompatible and nontoxic to human tissues, which integrates the entire optical imaging modules into a miniaturized, smartphone-based platform for field use and reduces the overall assay time to ∼5 min. The practicability of the wearable eye patch was demonstrated through accurate quantification of antibiotics in a bactericidal event and the continuous profiling of FQ residues in tears after using a typical prescription antibiotic eyedrop. This technology provides a useful supplement to the toolbox for on-site and real-time examination and regulation of inappropriate daily drug use that might potentially lead to long-term antibiotic abuse and has great implications in advancing personal healthcare techniques for the regulation of daily medication therapy.

Involuntary discharge from drug or alcohol treatment programs in Vancouver, Canada

BackgroundRetention in substance use treatment is essential to treatment success. While programmatic factors are known to influence retention, less is known about the role of involuntary discharges from drug or alcohol treatment programs. Therefore, we sought to identify the prevalence of and factors associated with involuntary discharge due to ongoing substance use.MethodsData were derived from two community-recruited prospective cohort studies of people who use drugs in Vancouver, Canada. Generalized estimating equation (GEE) analyses were used to identify variables associated with involuntary discharge from treatment programs due to ongoing substance use.ResultsBetween June 2017 and March 2020, 1487 participants who accessed substance use treatment and completed at least one study interview were included in this study. Involuntary discharge from a treatment program due to ongoing substance use was reported by 41 (2.8%) participants throughout the study, with 23 instances reported at baseline and another 18 reported during study follow-up. In a multivariable GEE analysis, involuntary discharge was positively associated with homelessness (Adjusted Odds Ratio [AOR] = 3.22, 95% Confidence Interval [95% CI]: 1.59–6.52), daily injection drug use (AOR = 1.87, 95% CI 1.06–3.32) and recent overdose (AOR = 2.50, 95% CI 1.38–4.53), and negatively associated with age (AOR = 0.93, 95% CI 0.90–0.96). In sub-analyses, participants have most commonly been discharged from in-patient treatment centres (52.2%), recovery houses (28.3%) and detox programs (10.9%), and for using heroin (45.5%) and/or crystal methamphetamine (36.4%).ConclusionsWhile involuntary discharge was a relatively rare occurrence, those who were discharged due to active substance use possessed several markers of risk, including high-intensity injection drug use, homelessness, and recent non-fatal overdose. Our findings highlight the need for increased flexibility within treatment programs to account for those who re-initiate or continue to use substances during treatment.

A Pilot Randomized Controlled Trial Evaluating Peer Recovery Coaches for Addiction Recovery among Indigenous Americans

Addiction is a common and devastating problem among many Indigenous American (IA) groups around the United States. Too few IA health care providers are available to deliver care in a way that leverages IA values and traditions to support addiction recovery. Peer Recovery Coaches (PRCs) are individuals who have lived experience of addiction and have received specialized training in helping others in recovery. IA PRCs hold significant potential in helping to fill the gap of culturally-specific support in addiction. In this feasibility trial, we recruited a total of 120 adult (≥19 years) IAs with a substance use disorder through Facebook advertisements. Ninety participants were randomized to the PRC (experimental) group which received support from PRC and 30 to the Attention-Control (AC) group which received support from research nurse. Both groups received weekly support for 12 weeks. Participants completed weekly surveys during the 12-week intervention and monthly surveys during a three-month follow-up phase. The two groups had similar quantities of alcohol consumed, days of alcohol use, and days of drug use except that the PRC group had fewer days of alcohol use in the first three weeks of the intervention phase (2.05 days v. 3.5 days, p=0.04). We found that “support and advocacy” was the most common intervention provided by the PRC. The PRC intervention was widely accepted and appreciated by individuals who completed the program with 79% of individuals giving positive feedback regarding the PRCs and the remaining 21% giving neutral feedback. This trial provides some insights upon which future trials can draw to further evaluate the potential of PRCs in this hard-to-reach population with a high level of need. Trials or programs that rely on national recruitment may be successful in reaching a sufficient number of individuals but they may lack the more intensive in-person capacity that will likely help with retention. Despite this limitation, the current pilot demonstrated that racially-concordant PRC services likely have a high degree of acceptability among IA populations. Future studies may draw on these findings by having trained IA coaches recruit and work with individuals in-person to assist with higher levels of retention.

The Effect of Veteran Status and Chronic Pain on Past 30-Day Sedative Use Among Community-Dwelling Adult Males.

Given the high sedative prescription rate, the sedative-associated morbidity, and mortality nationally (especially among veterans), we aimed to test the hypothesis that veteran status in the presence of chronic pain would be associated with greater sedative use when compared with nonveteran status. The study participants were recruited by Community Health Workers (CHWs) through the ongoing community engagement program (HealthStreet) at the University of Florida. CHWs collected information on sociodemographic factors, health status, and past 30-day drug use patterns. The study sample comprised 4,732 male participants, of which 21% were veterans, 58% were Blacks and 8.4% had used prescription sedatives in the past 30 days. Veterans (vs nonveterans) were twice as likely to have used prescription sedatives in the past 30 days in the presence of chronic pain. Veterans with chronic pain are a high-risk population for current prescription sedative use.

The outcome of integrated motivational interviewing and cognitive-behavioral therapy in Egyptian patients with substance use disorder

ObjectivesThe authors aimed to evaluate the outcome of combined motivational interviewing and cognitive-behavioral therapy (MICBT) for substance use disorder compared to the twelve-step facilitation (TSF) therapy in terms of retention in the treatment program, the number of relapses, and the period of abstinence after discharge, coping with craving, and modification of problematic behaviors.MethodThis randomized controlled trial included 60 individuals with a substance use disorder. Participants were randomly allocated to equal groups. The MICBT group received 20 sessions of approximately 90 min of MICBT group therapy. The NA (control) group was assigned 20 narcotic anonymous (NA)-oriented TSF group therapy sessions. The assessment was conducted 3 and 6 months after the intervention.ResultThe implementation of MICBT in a group setting leads to a significant decline in the number of days of drug use in 3 months of follow-up (P = 0.006) and 6 months of follow-up (P < 0.001), an increase in the number of days of abstinence in 3 months of follow-up (P = 0.008) and 6 months of follow-up (P < 0.001), a longer time to the first lapse (P < 0.001), and a higher percentage of attendance days for treatment (P < 0.001) in comparison to NA groups. MICBT intervention was a significant positive predictor of several urge-specific coping strategies and several general strategies for drugs (P < 0.05).ConclusionUsing MICBT in group settings presents several benefits in clinical contexts.

Telehealth Mindfulness-Oriented Recovery Enhancement vs Usual Care in Individuals With Opioid Use Disorder and Pain

Methadone treatment (MT) fails to address the emotion dysregulation, pain, and reward processing deficits that often drive opioid use disorder (OUD). New interventions are needed to address these factors. To evaluate the efficacy of MT as usual (usual care) vs telehealth Mindfulness-Oriented Recovery Enhancement (MORE) plus usual care among people with an OUD and pain. This study was a randomized clinical trial conducted from August 2020 to June 2022. Participants receiving MT for OUD and experiencing chronic pain were recruited at 5 clinics in New Jersey. In usual care, participants received MT, including medication and counseling. Participants receiving MORE plus usual care attended 8 weekly, 2-hour telehealth groups that provided training in mindfulness, reappraisal, and savoring in addition to usual care. Primary outcomes were return to drug use and MT dropout over 16 weeks. Secondary outcomes were days of drug use, methadone adherence, pain, depression, and anxiety. Analyses were based on an intention-to-treat approach. A total of 154 participants (mean [SD] age, 48.5 [11.8] years; 88 female [57%]) were included in the study. Participants receiving MORE plus usual care had significantly less return to drug use (hazard ratio [HR], 0.58; 95% CI, 0.37-0.90; P = .02) and MT dropout (HR, 0.41; 95% CI, 0.18-0.96; P = .04) than those receiving usual care only after adjusting for a priori-specified covariates (eg, methadone dose and recent drug use, at baseline). A total of 44 participants (57.1%) in usual care and 39 participants (50.6%) in MORE plus usual care returned to drug use. A total of 17 participants (22.1%) in usual care and 10 participants (13.0%) in MORE plus usual care dropped out of MT. In zero-inflated models, participants receiving MORE plus usual care had significantly fewer days of any drug use (ratio of means = 0.58; 95% CI, 0.53-0.63; P < .001) than those receiving usual care only through 16 weeks. A significantly greater percentage of participants receiving MORE plus usual care maintained methadone adherence (64 of 67 [95.5%]) at the 16-week follow-up than those receiving usual care only (56 of 67 [83.6%]; χ2 = 4.49; P = .04). MORE reduced depression scores and ecological momentary assessments of pain through the 16-week follow-up to a significantly greater extent than usual care (group × time F2,272 = 3.13; P = .05 and group × time F16,13000 = 6.44; P < .001, respectively). Within the MORE plus usual care group, EMA pain ratings decreased from a mean (SD) of 5.79 (0.29) at baseline to 5.17 (0.30) at week 16; for usual care only, pain decreased from 5.19 (0.28) at baseline to 4.96 (0.29) at week 16. Within the MORE plus usual care group, mean (SD) depression scores were 22.52 (1.32) at baseline and 18.98 (1.38) at 16 weeks. In the usual care-only group, mean (SD) depression scores were 22.65 (1.25) at baseline and 20.03 (1.27) at 16 weeks. Although anxiety scores increased in the usual care-only group and decreased in the MORE group, this difference between groups did not reach significance (group × time unadjusted F2,272 = 2.10; P= .12; Cohen d = .44; adjusted F2,268 = 2.33; P = .09). Within the MORE plus usual care group, mean (SD) anxiety scores were 25.5 (1.60) at baseline and 23.45 (1.73) at 16 weeks. In the usual care-only group, mean (SD) anxiety scores were 23.27 (1.75) at baseline and 24.07 (1.73) at 16 weeks. This randomized clinical trial demonstrated that telehealth MORE was a feasible adjunct to MT with significant effects on drug use, pain, depression, treatment retention, and adherence.

Generating synthetic data from administrative health records for drug safety and effectiveness studies.

Administrative health records (AHRs) are used to conduct population-based post-market drug safety and comparative effectiveness studies to inform healthcare decision making. However, the cost of data extraction, and the challenges associated with privacy and securing approvals can make it challenging for researchers to conduct methodological research in a timely manner using real data. Generating synthetic AHRs that reasonably represent the real-world data are beneficial for developing analytic methods and training analysts to rapidly implement study protocols. We generated synthetic AHRs using two methods and compared these synthetic AHRs to real-world AHRs. We described the challenges associated with using synthetic AHRs for real-world study. The real-world AHRs comprised prescription drug records for individuals with healthcare insurance coverage in the Population Research Data Repository (PRDR) from Manitoba, Canada for the 10-year period from 2008 to 2017. Synthetic data were generated using the Observational Medical Dataset Simulator II (OSIM2) and a modification (ModOSIM). Synthetic and real-world data were described using frequencies and percentages. Agreement of prescription drug use measures in PRDR, OSIM2 and ModOSIM was estimated with the concordance coefficient. The PRDR cohort included 169,586,633 drug records and 1,395 drug types for 1,604,734 individuals. Synthetic data for 1,000,000 individuals were generated using OSIM2 and ModOSIM. Sex and age group distributions were similar in the real-world and synthetic AHRs. However, there were significant differences in the number of drug records and number of unique drugs per person for OSIM2 and ModOSIM when compared with PRDR. For the average number of days of drug use, concordance with the PRDR was 16% (95% confidence interval [CI]: 12%-19%) for OSIM2 and 88% (95% CI: 87%-90%) for ModOSIM. ModOSIM data were more similar to PRDR than OSIM2 data on many measures. Synthetic AHRs consistent with those found in real-world settings can be generated using ModOSIM. Synthetic data will benefit rapid implementation of methodological studies and data analyst training.

Substance use, economic vulnerability, and HIV/STI risk among female sex workers in Mexico.

Economic hardship (e.g., difficulty to pay for basic needs) has been associated with increased HIV/STI risk among female sex workers (FSW), and may be exacerbated by high levels of substance use. Few studies have assessed the intersection of economic hardship, substance use, and HIV/STI risk among FSW. Quantitative data were collected via questionnaires among 469 FSW residing in Tijuana and Ciudad Juarez, Mexico. Using logistic regression, we assessed the role of economic hardship on the association between substance use (past 30-days alcohol use, drug use, or injection drugs use with clients, and past 6-months drug use) and testing positive for an STI (also an indicator of HIV risk). Drug use in the preceding six months was significantly associated with testing positive for an STI (AOR = 1.8, CI: 1.1 = 2.9, p = .02); no difference in this association was found by whether women reported economic hardship. Past 30-day drug use with clients was associated with STI infection, but only among those who did not report economic hardship (AOR = 1.5, 95% CI: 1.1-1.9, p < .01). Findings suggest that economic hardship influences the association between substance use and increased risk for HIV/STI among FSW; however, these associations may be more complex than previously hypothesized.

Making Harm Reduction More Accessible: Fentanyl Test Strip Awareness and Attitudes among Emergency Department Patients Who Use Drugs

Background Fentanyl test strips (FTS) are a harm reduction method for people to test their drugs for fentanyl. Ideal points for FTS distribution have not been identified. Many people who use drugs have frequent contact with the Emergency Department (ED). We piloted FTS distribution in two urban hospital EDs. Methods Between June-December 2021 in Philadelphia, PA, patients with past 30-day drug use completed a survey about drug use, fentanyl attitudes, and FTS; then offered FTS and a brief training. Survey data were analyzed using SPSS for bivariate statistics. Results Patients (n = 135) were primarily White (68.1%) and male (72.6%). Participants regularly interacted with substance use (57.8%) and benefits coordination (49.6%) services. The most common drugs used were heroin/fentanyl (68.9%), crack cocaine (45.2%) and cannabis (40.0%). Most (98.5%) had heard of fentanyl though few (18.5%) had ever used FTS. Across most drug types, participants were concerned about fentanyl. All accepted FTS training and distribution. Few (9.6%) were somewhat or very concerned about having FTS if stopped by police and this number varied by race (7.6% of White people were somewhat or very concerned, compared to 12.8% of Black people). Most participants were already engaged in risk reduction practices. Discussion FTS are a widely desired harm reduction tool to facilitate informed decision-making, and non-harm reduction locations are potentially feasible and acceptable distribution sites. Given regular contact with EDs and social services across the sample, FTS should be offered at non-harm reduction locations that come into frequent contact with people who use drugs.

Drug use patterns and factors related to the use and discontinuation of medications for opioid use disorder in the age of fentanyl: findings from a mixed-methods study of people who use drugs

BackgroundMedications for opioid use disorder (MOUD; methadone, buprenorphine, naltrexone) are the most effective treatments for OUD, and MOUD is protective against fatal overdoses. However, continued illegal drug use can increase the risk of treatment discontinuation. Given the widespread presence of fentanyl in the drug supply, research is needed to understand who is at greatest risk for concurrent MOUD and drug use and the contexts shaping use and treatment discontinuation.MethodsFrom 2017 to 2020, Massachusetts residents with past-30-day illegal drug use completed surveys (N = 284) and interviews (N = 99) about MOUD and drug use. An age-adjusted multinomial logistic regression model tested associations between past-30-day drug use and MOUD use (current/past/never). Among those on methadone or buprenorphine (N = 108), multivariable logistic regression models examined the association between socio-demographics, MOUD type; and past-30-day use of heroin/fentanyl; crack; benzodiazepines; and pain medications. Qualitative interviews explored drivers of concurrent drug and MOUD use.ResultsMost (79.9%) participants had used MOUD (38.7% currently; 41.2% past), and past 30-day drug use was high: 74.4% heroin/fentanyl; 51.4% crack cocaine; 31.3% benzodiazepines, and 18% pain medications. In exploring drug use by MOUD history, multinomial regression analyses found that crack use was positively associated with past and current MOUD use (outcome referent: never used MOUD); whereas benzodiazepine use was not associated with past MOUD use but was positively associated with current use. Conversely, pain medication use was associated with reduced odds of past and current MOUD use. Among those on methadone or buprenorphine, separate multivariable logistic regression models found that benzodiazepine and methadone use were positively associated with heroin/fentanyl use; living in a medium-sized city and sex work were positively associated with crack use; heroin/fentanyl use was positively associated with benzodiazepine use; and witnessing an overdose was inversely associated with pain medication use. Many participants qualitatively reported reducing illegal opioid use while on MOUD, yet inadequate dosage, trauma, psychological cravings, and environmental triggers drove their continued drug use, which increased their risk of treatment discontinuation and overdose.ConclusionsFindings highlight variations in continued drug use by MOUD use history, reasons for concurrent use, and implications for MOUD treatment delivery and continuity.

Intentional use of both opioids and cocaine in the United States

The combination of opioids and cocaine has been increasingly implicated in overdose fatalities, but it is unknown how much is intentional vs. fentanyl-adulterated drug supply. 2017–2019 data from the nationally representative National Survey on Drug Use and Health (NSDUH) was used. Variables included sociodemographics, health, and 30-day drug use. Opioid use captured heroin, and prescription pain reliever use not according to own doctor. Modified Poisson regressions were used to estimate prevalence ratios (PRs) for variables associated with opioid and cocaine use. Among the 167,444 responders, 817(0.49%) reported use of opioids on a regular or daily basis. Of these, 28% used cocaine ≥1 of prior 30 days, 11% >1 day. Of 332(0.20%) who used cocaine on a regular/daily basis, 48% used opioids ≥1 of prior 30 days, 25% >1 day. People with serious psychological distress were >6 times as likely to use both opioids and cocaine regularly/daily (PR = 6.48; 95% CI = [2.82–14.90]) and people who have never been married were 4 times as likely (PR = 4.17; 95% CI = [1.18–14.75]). Compared to those living in a small metropolitan region, people living in a large metropolitan region were >3 times as likely (PR = 3.29; 95% CI = [1.43–7.58]) and the unemployed were twice as likely (PR = 1.96; 95% CI = [1.03–3.73]). People with post-high school education were 53% less likely to use opioids and cocaine at least occasionally (PR = 0.47; 95% CI = [0.26–0.86]). People who use opioids or cocaine commonly choose to use the other. Knowing the characteristics of those most likely to use both should guide interventions for prevention and harm reduction.

Impact of Socioeconomic Status on Academic Achievement of Medical Students at Alzaiem Alazhari University 2021-2022

Socioeconomic status (SES), an index of one’s overall social status or prestige in society, is one of the most widely studied constructs in the social sciences. Student’s academic performance or gain is affected by several factors including socio economic status, school environment, family background, age, gender, parents’ academic levels, residential area of students, medium of instruction in schools, tuition trend, daily study hour, peer influence, drug and alcohol use, sexual activities and others. To study Impact of socioeconomic status on academic achievement among Alzaeim ALazhari medical students, 2021. This was a cross-sectional Descriptive Study conducted at Faculty of medicine at ALzaiem Alazhari University in Khartoum Bahri during the period from December 2021 to March 2022. We targeted medical students registered at Alzaiem Alazhari University. A questionnaire in a Google form was sent to them. This study included 208 participants. 57.2% of the participants were females, and 80.8% of them were in the age group between 21 and 23 years old. 43.7% of them had a family of high Socio-economic status. Regarding the GPA of the last semester a score between 3 and 3.4 was the most score achieved, this was the situation also regarding the continuous GPA. 90.3% of them said their parents supported them during education. In contrast, only 39.4% agreed that their parents’ level of education affected their educational attitude. age, father’s level of education, and participants who agreed that their parents’ level of education affects their educational attitude differed with a statistical significance with GPA. Factors found to be affecting GPA significantly were age, father’s level of education, and participants who agreed that their parents’ level of education affects their educational attitude. This study provided the community with data regarding socioeconomic status and academic achievement which can make a good base for others researches and a good quality of academic life The primary goal of education is to provide students with the knowledge, cognitive abilities, and career skills they will need to participate in society. Therefore, it is crucial to understand the elements influencing pupils' academic success.

Drug utilization pattern and cost estimates of antihypertensive drugs in pharmacies BPJS Kesehatan back-referral program in Kudus Regency

Background: Hypertension is one of the main causes of mortality and morbidity in Indonesia. Drug usage, utilization patterns, and cost estimates are important elements in calculating drug needs in the forecasting of drug needs plans for pharmacies. Objective: to determine the pattern of drug use with the Anatomical Therapeuetik Chemical (ATC)/Defined Daily Dose (DDD) and Drug Use 90% (DU90%) methods and the estimated cost of antihypertensives with the use of antihypertensive drugs based on the national formulary. Methods: This research uses observational methods using a cross-sectional design. Retrospective data collection includes prescription from BPJS Kesehatan back-referral program (PRB) which goes into pharmacy A, B, and C for the period 2020. Results: The most widely used drugs at pharmacy A, B and C based on ATC/DDD classification were amlodipine, candesartan, ramipril, hydrochlorothiazide, and lisinopril. Amlodipine was the most frequent drug in the DU segment 90%. The highest cost of using the drug was candesartan 16 mg (Rp 4,381,531). The percentages of adherence to the use of antihypertensive drugs with the national formulary in pharmacy A, B, and C were 73.91%, 80%, and 68.42%, respectively. Conclusion: In general, the highest consumption of antihypertensive drugs in Back-Referral Program (PRB) pharmacies in the area of Kudus Regency, which is included in the DU segment 90%, was amlodipine, and the suitability of drugs with the National Formulary has not reached 100%. Referring to the results of the pattern of use of PRB drugs in this study, it is hoped that there will be better coordination between BPJS Kesehatan and pharmacies regarding the distribution and availability of PRB drugs. Keywords: ATC/DDD, DU 90%, hypertension, national formulary, PRB

Hepatitis C virus prevalence, determinants, and cascade of care among people who inject drugs in Iran

BackgroundPeople who inject drugs (PWID) continue to experience the highest burden of hepatitis C virus (HCV). We aimed to characterize HCV antibody prevalence, determinants of infection, and the cascade of engagement in HCV care among PWID in Iran. MethodsParticipants were recruited in 11 cities of Iran using respondent-driven sampling. PWID underwent a structured interview capturing measures on socio-demographics, behaviors, and the HCV cascade of care. HCV and HIV were tested using antibody rapid tests. Multivariable logistic regression models identified characteristics associated with HCV seropositivity. ResultsHCV antibody prevalence was 26.0% among 2684 PWID enrolled. Of 699 participants who were HCV antibody positive, 88 (12.6%) were aware of past infections. HCV antibody prevalence was associated with older age (adjusted odds ratio [aOR] 2.09; 95% CI 1.18, 3.71), lower education (aOR 1.31; 95% CI 1.02, 1.69), >10 years of injecting (aOR 6.03; 95% CI 4.10, 8.85), methamphetamine injection (aOR 1.46; 95% CI 1.07, 1.99), daily injection drug use (aOR 1.26; 95% CI 1.01, 1.58), needle/syringe sharing (aOR 2.04; 95% CI 1.24, 3.34), recent incarceration (aOR 1.74; 95% CI 1.30, 2.32), and HIV seropositivity (aOR 7.93; 95% CI 4.12, 15.24). Additionally, 12.0% had ever tested for HCV, 4.0% had previously tested reactive for HCV antibody, and 3.7% had received an HCV diagnosis. Of diagnosed cases, 44.4% were linked to care, 15.2% initiated treatment, and 3.0% achieved sustained virologic response. ConclusionOur data show a high prevalence of HCV antibody and low engagement in HCV care, underscoring an unmet need for HCV prevention, screening, and treatment among PWID in Iran. HCV prevention and treatment programs tailored for PWID are needed to enhance harm reduction efforts and access to HCV care in Iran.

799. Unstable Housing, Daily Drug Use, and Transactional Sex are Associated with Viremia in Transgender Individuals Living with HIV

Abstract Background In the United States, HIV is highly prevalent among transgender individuals, but factors contributing to viremia in this population are poorly understood. We aimed to assess factors associated with HIV viremia among transgender people living with HIV (PLWH). Methods PATCH is a longitudinal natural history study of transgender individuals in Washington, DC. Participants complete laboratory assessments, as well as surveys assessing demographics, behaviors, and mental health. Patients whose HIV viral load was &amp;gt;200 copies/mL at screening were considered viremic. Fisher’s exact test was used for statistical analysis. Results Of 62 enrolled participants, 35(56%) were HIV+, the majority of whom were prescribed antiretroviral therapy (31, 89%) and had an undetectable viral load (25, 71%). Of PLWH, 35(100%) were assigned male at birth, 34(97%) were Black, and the median age was 37 years. PLWH were predominately stably housed (24, 69%), with 9(26%) reporting daily drug use or more, and 16(46%) reporting transactional sex within a year. When comparing PLWH who were viremic versus those virally suppressed, viremic PLWH were less likely to be prescribed antiretroviral therapy (60% vs 100%, p=0.004), and more likely to have unstable housing (60% vs 25%, p=0.04), use drugs daily or more in the last month (60% vs 12%, p=0.007), and engage in transactional sex in the last 12 months (80% vs 32%, p=0.02). HIV viral suppression was not significantly associated with number of sexual partners within the last 12 months or always using condoms during any type of sex (p &amp;gt;0.05). Conclusion In this cohort of transgender PLWH, we found moderate rates of HIV viremia associated with chaotic life factors such as daily drug use, unstable housing, and engaging in transactional sex. In addition, we found low rates of consistent condom use despite multiple sexual partners, regardless of viral load. Comprehensive care programs that improve access to ART, address substance use disorders and facilitate housing may serve to improve treatment outcomes and reduce risk of HIV transmission in this population.

Antecedents of subjective severity of detention and perceived procedural justice

ABSTRACT In this paper, we study what factors contribute to the extent that detained individuals (a) perceive their time in detention as severe and (b) perceive their treatment by prison staff as procedurally just. More specifically, the aim of the study is to examine the antecedents of subjective severity of detention (SSD) and perceived procedural justice (PPJ) with the aim to identify individual and situational characteristics that contribute to such perceptions. Our analyses were based on data from the Prison Project (n = 1430), which includes detailed information on measures of SSD, and PPJ among Dutch males held in Dutch penitentiary institutions. Based on their SSD and PPJ scores, detained individuals were classified as belonging to one of four subgroups (reference group, high SSD, high PPJ, or high both). Using a large set of background variables, we found that older age, a less elaborate criminal history, no daily drug use before arrest, not having experienced any victimization by prison staff, and the personality traits of neuroticism, conscientiousness, and agreeableness were the most relevant antecedents for ‘high both’ subgroup membership.

Cohort Profile: The Assessing Economic Transitions (ASSET) Study-A Community-Based Mixed-Methods Study of Economic Engagement among Inner-City Residents.

The Assessing Economic Transitions (ASSET) study was established to identify relationships between economic engagement, health and well-being in inner-city populations given that research in this area is currently underdeveloped. This paper describes the objectives, design, and characteristics of the ASSET study cohort, an open prospective cohort which aims to provide data on opportunities for addressing economic engagement in an inner-city drug-using population in Vancouver, Canada. Participants complete interviewer-administered surveys quarterly. A subset of participants complete nested semi-structured qualitative interviews semi-annually. Between April 2019 and May 2022, the study enrolled 257 participants ages 19 years or older (median age: 51; 40% Indigenous, 11.6% non-Indigenous people of colour; 39% cis-gender women, 3.9% transgender, genderqueer, or two-spirit) and 41 qualitative participants. At baseline, all participants reported past daily drug use, with 27% currently using opioids daily, and 20% currently using stimulants daily. In the three months prior to baseline, more participants undertook informal income generation (75%) than formal employment (50%). Employed participants largely had casual jobs (42%) or jobs with part-time/varied hours (35%). Nested qualitative studies will focus on how inner-city populations experience economic engagement. The resulting evidence will inform policy and programmatic initiatives to address socioeconomic drivers of health and well-being.

Sexual behavior and medication adherence in men who have sex with men participating in a pre-exposure prophylaxis study of combinations of Maraviroc, Tenofovir Disoproxil Fumarate and/or Emtricitabine (HPTN 069/ACTG 5305).

HPTN 069/ACTG 5305 was designed to evaluate potential new PrEP regimens that included maraviroc, tenofovir disoproxil fumarate, and/or emtricitabine. The current analyses assessed antiretroviral (ARV) plasma concentrations in relation to sexual behavior in 224 cisgender men who have sex with men and 2 transgender women at risk for HIV. Poisson generalized estimating equations (GEE) regression were used to test for associations between self-reported sexual behavior, sociodemographic, behavioral variables, and study drug levels The median (IQR) age was 30 [25, 37] years old; 48.2% had completed college; 27.4% were Black and 21.7% Latino. At weeks 24 and 48, one third of participants reported condomless anal sex (CAS) in the prior month with more than one partner. CAS was associated with daily ARV drug use (χ2 = 12.64, p = 0.002). Older individuals and those with greater education were more likely to ingest ARV drugs daily (χ2 = 9.36, p = 0.009 and χ2 = 8.63, p = 0.013, respectively), while neither race nor ethnicity was associated with daily ARV drug use. Participants who reported recent condomless anal sex and/or advanced education had higher rates of daily ARV drug use. These data support the need for ongoing adherence counseling in clinical trials of new PrEP modalities.

Short-term effects of modest salt reduction combined with DASH diet on changing salt eating habits in hypertensive patients with type II diabetes

ABSTRACT Objective Excessive salt intake is currently the foremost universal risk factor for controllable chronic disease. This study evaluated the short-term effects of a modest salt intake reduction combined with the Chinese Modified Dietary Approaches to Stop Hypertension (CM-DASH) diet on sodium and potassium intake, mean arterial pressure (MAP), and pulse pressure (PP) in hypertensive patients with type II diabetes. Methods Sixty-one participants were randomized to the intervention group (52% low-sodium salt and DASH) and control group (normal salt and DASH). An 8-week dietary intervention was applied. Daily salt intake, blood pressure (BP), and drug use were recorded every week. Twenty-four-hour urine, casual urine, and blood samples were measured at baseline, the 4th week, and the end of the intervention. Results Fifty-nine patients (25 men) completed the entire study. Sodium intake decreased by 1259.66 (792.76, 1726.56)/705.80 (149.21, 1262.39) mg/day after 4 weeks (intervention: P < .001; control: P = .015). Potassium intake increased by 641.14 (73.31, 1208.96)/43.43 (−259.66, 346.53) mg/day (intervention: P = .028); MAP decreased by 9.06 (6.69, 11.43)/7.16 (4.03, 10.28) mmHg (both: P < .001); PP decreased by 7.97 (3.05, 12.88)/5.74 (2.55,8.94) mmHg (intervention: P = .002; control: P = .001) after 8 weeks. However, the difference between the two groups was not statistically significant. Conclusion Modest salt reduction and the CM-DASH diet for hypertensive patients with type II diabetes can achieve short-term salt reduction effects. The effect on changing salt-eating habits needs to be investigated with an extended follow-up.
