ABSTRACT
INTRODUCTION: Stigma has negative consequences for the health of people who inject drugs and people living with hepatitis C virus (HCV). This study evaluated factors associated with stigma related to injecting drug use (IDU) or HCV and those associated with being treated negatively by health workers. METHODS: ETHOS Engage is an observational cohort study of people who inject drugs attending drug treatment clinics and needle and syringe programs in Australia. Participants completed a questionnaire including IDU- and HCV-related stigma, and negative treatment by health workers. Logistic regression was used to identify factors associated with experiencing stigma and negative treatment in a cross-sectional sample. RESULTS: Of 1,211 participants, 31% were women, 64% had injected drugs in the previous month, and 65% had been diagnosed with HCV. IDU-related stigma was reported by 57% of participants and was associated with being a woman, higher than Year 10 education, homelessness, opioid agonist treatment, recent injecting, overdose history, hospitalisation for drug use, and unknown HCV status. HCV-related stigma was reported by 34% of participants diagnosed with HCV and was associated with being a woman, homelessness, receptive needle/syringe sharing, arrest for drug use/possession, and recent HCV testing. Negative treatment from health workers was reported by 45% of participants and was associated with being a woman, receptive needle/syringe sharing, hospitalisation for drug use, and arrest for drug use/possession. DISCUSSION AND CONCLUSIONS: Results highlight important intersections and disparities in stigmatising experiences among people who inject drugs. Considering these intersections can assist health services provide more inclusive care.

INTRODUCTION: Understanding needle/syringe sharing is crucial for reducing hepatitis C virus (HCV) infection and reinfection. This study aimed to assess the prevalence and factors associated with needle/syringe sharing among people who inject drugs in Australia, including those previously receiving HCV treatment. METHODS: The ETHOS Engage study was an observational cohort study which collected self-reported survey data on demographic and drug use information from people who inject drugs attending drug treatment clinics and needle and syringe programs over two waves between May 2018 and June 2021. Logistic regression was used to identify factors associated with needle/syringe sharing. RESULTS: Overall, 1555/2395 people enrolled in ETHOS Engage (65%) injected drugs in the past month. Among these, 432 (28%) reported needle/syringe sharing in the past month and 276 (18%) reported receptive sharing. Factors associated with receptive sharing included younger age (adjusted odds ratio [aOR] 1.72; 95% confidence interval [CI] 1.28-2.30), recent incarceration (aOR 2.04; 95% CI 1.40-2.94), more frequent injecting (≥daily vs. less than weekly; aOR 2.59; 95% CI 1.75-3.84) and unstable housing (aOR 1.78; 95% CI 1.26-2.52). Among 560 participants with prior HCV treatment, 87 (16%) reported receptive sharing with younger age (aOR 2.42; 95% CI 1.45-4.05) and daily or greater injection frequency (aOR 2.51; 95% CI 1.31-4.83) associated with receptive sharing. DISCUSSION AND CONCLUSIONS: Needle/syringe sharing was common among this population accessing harm reduction services. This study identifies high-risk populations with needle/syringe sharing. Research is needed to optimise HCV treatment to ensure people with ongoing risk behaviours receive adequate harm reduction following treatment to prevent reinfection.

Direct-acting antivirals (DAAs) for hepatitis C virus (HCV) infection have delivered high response rates (>95%) and simplified the management of HCV treatment, permitting non-specialists to manage patients without advanced liver disease. We collected and reviewed global data on the registration and reimbursement (government subsidised) of HCV therapies, including restrictions on reimbursement. Primary data collection occurred between Nov 15, 2021, and July 24, 2023, through the assistance of a global network of 166 HCV experts. We retrieved data for 160 (77%) of 209 countries and juristrictions. By mid-2023, 145 (91%) countries had registered at least one of the following DAA therapies: sofosbuvir-velpatasvir, sofosbuvir-velpatasvir-voxilaprevir, glecaprevir-pibrentasvir, sofosbuvir-daclatasvir, or sofosbuvir. 109 (68%) countries reimbursed at least one DAA therapy. Among 102 low-income and middle-income countries (LMICs), 89 (87%) had registered at least one HCV DAA therapy and 53 (52%) reimbursed at least one DAA therapy. Among all countries with DAA therapy reimbursement (n=109), 66 (61%) required specialist prescribing, eight (7%) had retreatment restrictions, seven (6%) had an illicit drug use restriction, five (5%) had an alcohol use restriction, and three (3%) had liver disease restrictions. Global access to DAA reimbursement remains uneven, with LMICs having comparatively low reimbursement compared with high-income countries. To meet WHO goals for HCV elimination, efforts should be made to assist countries, particularly LMICs, to increase access to DAA reimbursement and remove reimbursement restrictions-especially prescriber-type restrictions-to ensure universal access.

BACKGROUND: People who inject drugs are disproportionately affected by HIV and hepatitis C virus (HCV) infections, while there is little global data on HIV and HCV testing and treatment coverage of this population. We conducted a systematic review to evaluate country-level, regional, and global coverage of HIV and HCV testing and treatment among people who inject drugs. METHODS: We did a systematic review, and searched bibliographic databases (MEDLINE, Embase, and PsycINFO) and grey literature for studies published between Jan 1, 2017, and April 30, 2022, that evaluated the proportion of people who inject drugs who received testing or treatment for HIV or HCV. For each country, we estimated the proportion of people who inject drugs tested for HIV antibodies in the past 12 months (recent), people who inject drugs ever tested for HCV antibodies and HCV RNA, people who inject drugs with HIV currently receiving antiretroviral therapy, and people who inject drugs with HCV ever receiving HCV antiviral treatment. Regional and global estimates, weighted by the population size of people who inject drugs, were generated where sufficient data were available. This study is registered with PROSPERO (CRD42020173974). FINDINGS: 512 documents reported data eligible for analyses, including 337 peer-reviewed articles, 27 conference abstracts or presentations, and 148 documents from grey literature or supplementary searches. Data of recent HIV antibody testing were available for 67 countries and ever having had HCV antibody testing were available for 49 countries. Globally, an estimated 48·8% of people who inject drugs were recently tested for HIV antibodies (95% uncertainty interval [UI] 43·3-54·2%; range 0·9-86·0%), and 47·1% had ever been tested for HCV antibodies (95% UI 43·4-51·0%; range 0·0-93·3%). HCV RNA testing data were available from three countries. Coverage of HIV antibody testing was high (>75%) in four countries and for HCV antibody testing in 15 countries. The estimated uptake of current HIV treatment (18 countries) ranged from 2·6% to 81·9%, and the estimated uptake of ever having HCV treatment (23 countries) ranged from 1·8% to 88·6% across countries. Uptake of HIV treatment was high in two countries, and of HCV treatment in one country. INTERPRETATION: HIV and HCV testing and treatment uptake among people who inject drugs was highly variable, and suboptimal in most countries. Strategies to improve access to HIV and HCV care among people who inject drugs and the availability of public health surveillance are urgently required.

BACKGROUND: Transitional times in opioid use, such as release from prison and discontinuation of opioid agonist treatment (OAT), are associated with health harms due to changing drug consumption practices and limited access to health and social supports. Using a self-controlled (within-person) study design, we aimed to understand if these transitions increase risks of injection drug use-associated bacterial infections. METHODS: We performed a self-controlled case series among a cohort of people with opioid use disorder (who had all previously accessed OAT) in New South Wales, Australia, 2001-2018. The outcome was hospitalisation with injecting-related bacterial infections. We divided participants' observed days into time windows related to incarceration and OAT receipt. We compared hospitalization rates during focal (exposure) windows and referent (control) windows (i.e., 5-52 weeks continuously not incarcerated or continuously receiving OAT). We estimated adjusted incidence rate ratios (aIRR) using conditional logistic regression, adjusted for time-varying confounders. RESULTS: There were 7590 participants who experienced hospitalisation with injecting-related bacterial infections (35% female; median age 38 years; 78% hospitalised with skin and soft-tissue infections). Risk for injecting-related bacterial infections was elevated for two weeks following release from prison (aIRR 1.45; 95%CI 1.22-1.72). Risk was increased during two weeks before (aIRR 1.89; 95%CI 1.59-2.25) and after (aIRR 1.91; 95%CI 1.54-2.36) discontinuation of OAT, and during two weeks before (aIRR 3.63; 95%CI 3.13-4.22) and after (aIRR 2.52; 95%CI 2.09-3.04) OAT initiation. CONCLUSION: Risk of injecting-related bacterial infections varies greatly within-individuals over time. Risk is raised immediately after prison release, and around initiation and discontinuation of OAT. Social contextual factors likely contribute to excess risks at transitions in incarceration and OAT exposure.

Rates of parental incarceration in the USA have increased dramatically over the past four decades. The Adverse Childhood Experiences study identified parental incarceration as one of several risk factors related to multiple health outcomes during childhood and adulthood. Parents and other caregivers are widely regarded as sources of resilience for children experiencing adversity, yet few studies have examined caregivers' parenting practices as sources of resilience for children with incarcerated parents. This study used secondary data from a longitudinal randomized controlled trial of the prison-based parent management training program Parenting Inside Out (PIO). Specifically, it included 149 caregivers (i.e., the non-incarcerated parent, extended family member, or other adult who provides the day-to-day caretaking of a child during parental incarceration) of children aged 2-14 years whose incarcerated parents were randomly assigned to receive PIO or the control condition. Path analysis was used to examine associations between caregivers' parenting, social support, self-efficacy, and change in child internalizing and externalizing symptoms across a 6-month period. Direct effects of caregivers' parenting were found on improvements in child behavioral health from baseline (conducted when the parent was incarcerated) to the 6-month follow-up (conducted after most parents had been released). Indirect effects were found for caregiver social support and self-efficacy. The findings highlight the importance of caregivers' adaptive parenting as a protective resource for children who experience parental incarceration and have implications for the design of preventive interventions for this underserved population.

BACKGROUND: Harm reduction and treatment programmes are essential for reducing harms for people who inject drugs (PWID). We aimed to update estimates from a 2017 review of global coverage of needle and syringe exchange programmes (NSPs), opioid agonist treatment (OAT), and other harm reduction services that target PWID (eg, take-home naloxone [THN] programmes, supervised consumption facilities, and drug checking services). METHODS: We did a systematic review of available evidence from peer-reviewed and grey literature databases for studies published between Jan 1, 2017, and May 31, 2022. Programmatic data were collected on the availability of services, the number of sites, people accessing services, and equipment distributed in countries where there is evidence of injecting drug use. National estimates of coverage of OAT (ie, number of people accessing OAT per 100 PWID) and NSPs (ie, number of needles and syringes distributed per PWID per year) were generated where available using the most recent data. Regional and global estimates were derived and compared with WHO indicators. The study was registered with PROSPERO (CRD42020173974). FINDINGS: We included 195 studies and found there were 90 countries implementing OAT (75% of the PWID population) and 94 countries implementing NSPs (88% of the global PWID population). Only five countries (2% of the global PWID population) are providing high coverage of both services. Far fewer countries were implementing THN programmes (n=43), supervised consumption facilities (n=17), and drug checking services (n=26), with nine countries implementing all five services. Globally, we estimated there were 18 (95% uncertainty interval [UI] 12-27) people accessing OAT per 100 PWID, and 35 (95% UI 24-52) needles and syringes being distributed per person who injects drugs per year. More countries reported high (OAT 24; NSPs 10), moderate (OAT 8; NSPs 15), and low (OAT 38; NSPs 47) coverage of services compared with the previous review. INTERPRETATION: Global coverage of OAT and NSPs has increased modestly in the past 5 years but remains low for most countries. Programmatic data on other key harm reduction interventions are scarce.

BACKGROUND: People who inject drugs are exposed to various and changing risk environments and are at risk of multiple harms related to injecting drug use (IDU). We aimed to undertake a global systematic review of the prevalence of IDU, key IDU-related harms (including HIV, hepatitis C virus [HCV], and hepatitis B virus [HBV] infection and overdose), and key sociodemographic characteristics and risk exposures for people who inject drugs. METHODS: We systematically searched for data published between Jan 1, 2017, and March 31, 2022, in databases of peer-reviewed literature (MEDLINE, Embase, and PsycINFO) and grey literature as well as various agency or organisational websites, and disseminated data requests to international experts and agencies. We searched for data on the prevalence, characteristics, and risks of people who inject drugs, including gender, age, sexuality, drug-use patterns, HIV, HCV, and HBV infections, non-fatal overdose, depression, anxiety, and injecting-related disease. Additional data were extracted from studies identified in our previous review. Meta-analyses were used to pool the data where multiple estimates were available for a country. We present country, regional, and global estimates for each variable examined. FINDINGS: We screened 40 427 reports published between 2017 and 2022, and the 871 eligible reports identified were added to the 1147 documents from the previous review. Evidence of IDU was documented in 190 of 207 countries and territories, and 14·8 million people (95% uncertainty interval [UI] 10·0-21·7) aged 15-64 years globally were estimated to inject drugs. Existing evidence suggests that there might be 2·8 million (95% UI 2·4-3·2) women and 12·1 million (95% UI 11·0-13·3) men who inject drugs globally, and that 0·4% (95% CI 0·3-1·3) of people who inject drugs identify as transgender. The amount of available data on key health and social risks among people who inject drugs varied widely across countries and regions. We estimated that 24·8% (95% CI 19·5-31·6) of people who inject drugs globally had experienced recent homelessness or unstable housing, 58·4% (95% CI 52·0-64·8) had a lifetime history of incarceration, and 14·9% (95% CI 8·1-24·3) had recently engaged in sex work, with substantial geographical variation. Injecting and sexual risk behaviour varied considerably geographically, as did risks of harms. Globally, we estimated that 15·2% (95% CI 10·3-20·9) of people who inject drugs are living with HIV, 38·8% (95% CI 31·4-46·9) have current HCV infection, 18·5% (95% CI 13·9-24·1) have recently overdosed, and 31·7% (95% CI 23·6-40·5) have had a recent skin or soft tissue infection. INTERPRETATION: IDU is being identified in a growing number of countries and territories that comprise more than 99% of the global population. IDU-related health harms are common, and people who inject drugs continue to be exposed to multiple adverse risk environments. However, quantification of many of these exposure and harms is inadequate and must be improved to allow for better targeting of harm-reduction interventions for these risks.

BACKGROUND: With the advent of direct acting antiviral (DAA) therapies for the treatment of hepatitis C virus (HCV), the World Health Organization recommended a goal to eliminate HCV as a public health threat globally by 2030. With the majority of new and existing infections in high income countries occurring among people who inject drugs, achieving this goal will require the design and implementation of interventions which address the unique barriers to HCV care faced by this population. METHODS: In this systematic review and meta-analysis, we searched bibliographic databases and conference abstracts to July 21, 2020 for studies assessing interventions to improve the following study outcomes: HCV antibody testing, HCV RNA testing, linkage to care, and treatment initiation. We included both randomised and non-randomised studies which included a comparator arm. We excluded studies which enrolled only paediatric populations (<18 years old) and studies where the intervention was conducted in a different healthcare setting than the control or comparator. This analysis was restricted to studies conducted among people who inject drugs. Data were extracted from the identified records and meta-analysis was used to pool the effect of interventions on study outcomes. This study was registered in PROSPERO (CRD42020178035). FINDINGS: Of 15,342 unique records, 45 studies described the implementation of an intervention to improve HCV testing, linkage to care and treatment initiation among people who inject drugs. These included 27 randomised trials and 18 non-randomised studies with the risk of bias rated as "critical" for most non-randomised studies. Patient education and patient navigation to address patient-level barriers to HCV care were shown to improve antibody testing uptake and linkage to HCV care respectively although patient education did not improve antibody testing when restricted to randomised studies. Provider care coordination to address provider level barriers to HCV care was effective at improving antibody testing uptake. Three different interventions to address systems-level barriers to HCV care were effective across different stages of HCV care: point-of-care antibody testing (linkage to care); dried blood-spot testing (antibody testing uptake); and integrated care (linkage to care and treatment initiation). INTERPRETATION: Multiple interventions are available that can address the barriers to HCV care for people who inject drugs at the patient-, provider-, and systems-level. The design of models of care to improve HCV testing and treatment among people who inject drugs must consider the unique barriers to care that this population faces. Further research, including high-quality randomised controlled trials, are needed to robustly assess the impact these interventions can have in varied populations and settings.

BACKGROUND: Injecting-related skin and soft tissue infections (SSTIs) are a preventable cause of inpatient hospitalisation among people who inject drugs (PWID). This study aimed to determine the prevalence of hospitalisation for SSTIs among PWID, and identify similarities and differences in factors associated with hospitalisation for SSTIs versus non-bacterial harms related to injecting drug use. METHODS: We performed cross-sectional analyses of baseline data from an observational cohort study of PWID attending drug treatment clinics and needle and syringe programs in Australia. Logistic regression models were used to identify factors associated with self-reported hospitalisation for (1) SSTIs (abscess and/or cellulitis), and (2) non-bacterial harms related to injecting drug use (e.g., non-fatal overdose; hereafter referred to as non-bacterial harms), both together and separately. RESULTS: 1851 participants who injected drugs in the previous six months were enrolled (67% male; 85% injected in the past month; 42% receiving opioid agonist treatment [OAT]). In the previous year, 40% (n = 737) had been hospitalised for drug-related causes: 20% (n = 377) and 29% (n = 528) of participants were admitted to hospital for an SSTI and non-bacterial harm, respectively. Participants who were female (adjusted odds ratio [aOR]: 1.53, 95% CI: 1.19-1.97) or homeless (aOR: 1.59, 95% CI: 1.16-2.19) were more likely to be hospitalised for an SSTI, but not a non-bacterial harm. Both types of hospitalisation were more likely among people recently released from prison. CONCLUSIONS: Hospitalisation for SSTIs is common among PWID. Community-based interventions to prevent SSTIs and subsequent hospitalisation among PWID will require targeting of at-risk groups, including women, people experiencing homelessness, and incarcerated people upon prison release.

BACKGROUND: Despite the goal set by WHO to eliminate hepatitis C virus (HCV) as a public health threat, uptake of HCV testing and treatment remains low. To achieve this target, evidence-based interventions are needed to address the barriers to care for people with, or at risk of, HCV infection. We aimed to assess the efficacy of interventions to improve HCV antibody testing, HCV RNA testing, linkage to HCV care, and treatment initiation. METHODS: In this systematic review and meta-analysis, we searched MEDLINE (PubMed), Scopus, Web of Science, the Cochrane Central Register of Controlled Trials, and PsycINFO without language restrictions for reports published between database inception and July 21, 2020, assessing the following primary outcomes: HCV antibody testing; HCV RNA testing; linkage to HCV care; and direct-acting antiviral treatment initiation. We also searched key conference abstracts. We included randomised and non-randomised studies assessing non-pharmaceutical interventions that included a comparator or control group. Studies were excluded if they enrolled only paediatric populations (aged <18 years) or if they conducted the intervention in a different health-care setting to that of the control or comparator. Authors were contacted to clarify study details and to obtain additional population-level data. Data were extracted from the records identified into a pre-piloted and standardised data extraction form and a random-effects meta-analysis was used to pool the effects of the interventions on study outcomes. This study is registered in PROSPERO, CRD42020178035. FINDINGS: Of 15 342 unique records identified, 142 were included, which reported on 148 unique studies (47 randomised controlled trials and 101 non-randomised studies). Medical chart reminders, provider education, and point-of-care antibody testing significantly improved at least three study outcomes compared with a comparator or control. Interventions that simplified HCV testing, including dried blood spot testing, point-of-care antibody testing, reflex RNA testing, and opt-out screening, significantly improved testing outcomes compared with a comparator or control. Enhanced patient and provider support through patient education, provider care coordination, and provider education also significantly improved testing outcomes compared with a comparator or control. Integrated care and patient navigation or care coordination significantly improved linkage to care and the uptake of direct-acting antiviral treatment compared with a comparator or control. INTERPRETATION: Several interventions to improve HCV care that address several key barriers to HCV care were identified. New models of HCV care must be designed and implemented to address the barriers faced by the population of interest. Further high-quality research, including rigorously designed randomised studies, is still needed in key populations. FUNDING: None.

BACKGROUND: Finger-stick point-of-care and dried blood spot (DBS) hepatitis C virus (HCV) RNA testing increases testing uptake and linkage to care. This systematic review evaluated the diagnostic accuracy of point-of-care testing and DBS to detect HCV RNA. METHODS: Bibliographic databases and conference presentations were searched for eligible studies. Meta-analysis was used to pool estimates. RESULTS: Of 359 articles identified, 43 studies were eligible and included. When comparing the Xpert HCV Viral Load Fingerstick assay to venous blood samples (7 studies with 987 samples), the sensitivity and specificity for HCV RNA detection was 99% (95% confidence interval [CI], 97%-99%) and 99% (95% CI, 94%-100%) and for HCV RNA quantification was 100% (95% CI, 93%-100%) and 100% (95% CI, 94%-100%). The proportion of invalid results following Xpert HCV Viral Load Fingerstick testing was 6% (95% CI, 3%-11%). When comparing DBS to venous blood samples (28 studies with 3988 samples) the sensitivity and specificity for HCV RNA detection was 97% (95% CI, 95%-98%) and 100% (95% CI, 98%-100%) and for HCV RNA quantification was 98% (95% CI, 96%-99%) and 100% (95% CI, 95%-100%). CONCLUSIONS: Excellent diagnostic accuracy was observed across assays for detection of HCV RNA from finger-stick and DBS samples. The proportion of invalid results following Xpert HCV Viral Load Fingerstick testing highlights the importance of operator training and quality assurance programs.

Physical or perceived (i.e. loneliness) social isolation is increasing in Western cultures. Unfortunately, social isolation is associated with a range of negative physical and mental health outcomes, including increased incidence of obesity and smoking. Here we monitored the impact of social isolation on a range of physical measures, and then tested whether social isolation in adult rats changes how reward-related stimuli motivate sucrose- or nicotine-seeking. Socially isolated rats showed elevated baseline CORT, gained significantly less weight across the study, were more active in response to a novel or familiar environment. Isolated rats also acquired nose-poking for a food pellet more rapidly, and showed increased susceptibility to cue-, but not reward-induced reinstatement. Notably, these effects are partially mitigated by a return to group housing, suggesting that they are not necessarily permanent, and that a return to a social setting can quickly reverse any deficits or changes associated with social isolation. This study advances our understanding of altered reward-processing in socially isolated individuals and reiterates the importance of socialisation in the treatment of disorders such as overeating and addiction.

Intra-vesical Bacillus Calmette-Guérin (BCG) immunotherapy is an effective treatment for high-risk bladder cancer. Less well known is that fewer than 1% of patients receiving BCG treatment can develop disseminated BCG. The reaction can range from a mild flu-like illness to a systemic disorder with a fulminant course which in the most severe cases can lead to death. The diagnostic yield is low and diagnosis is often made after a comprehensive exclusion of more common causes of pyrexia of unknown origin. A high level of suspicion is therefore required in those who may be at risk. We report a case of disseminated BCG in an older patient for whom early involvement of his family was pertinent to determining the precipitant for delirium.

An independent, randomized controlled trial of the community-developed, multiple-component Relief Nursery prevention program was conducted with families with young children considered "at risk" for child abuse and neglect. This established program, currently operating at multiple sites in the state of Oregon, comprises an integrated package of prevention services to children and families, including early childhood education, home visiting, and parent education and support, as well as other interventions tailored to the needs of each particular family. Families who contacted the Relief Nursery for the first time were randomly assigned to one of two conditions, the Full Program condition, whose members had access to all services available from the Relief Nursery, or the Respite Care condition, whose members had access only to respite care and referrals to services provided by other community agencies. A primary caregiver in each family was interviewed prior to intervention and then every 6 months across a period of 2 years. Standardized measures were collected on a variety of risk and protective factors related to child abuse and neglect. Analyses were conducted at the end of the study period. Differences were found between the conditions in terms of perceived helpfulness and satisfaction with services and in terms of social support, in each case favoring the Full Program condition. Implications of the findings for future studies of multicomponent child abuse prevention programs with similar characteristics to the Relief Nursery are discussed.

Child outcomes due to a paid professional mentoring program, Friends of the Children (FOTC), were investigated across the first 5 years of an ongoing multi-site randomized controlled trial. Participants were 278 children attending kindergarten or first grade who were identified as "at risk" for adjustment problems during adolescence. The program was delivered through established nonprofit community-based organizations. Mentors were hired to work full time and were provided training, supervision, and support to work individually with small numbers of children. Recruitment took place across a 3-year period. Random assignment to the intervention condition or a services as usual control condition was conducted at the level of the individual, blocking on school and child sex. After the initial assessment, follow-up assessments were conducted every 6 months. Differences in growth curves across the elementary school years were examined in intent-to-treat analyses. Significant effects favoring FOTC were found in terms of caregiver ratings of positive school behavior and less trouble in school, with a trend for higher child behavioral and emotional strengths. Effect sizes were in the range typical in recent trials of youth mentoring.
