BACKGROUND:Previous studies have postulated that four structural compartments may be differentiated in hair: surface protein domain, water-accessible protein domain, water-inaccessible protein domain, and melanin. Drugs contained in blood, sweat, sebum, and environment would be deposited in the first two domains, with primarily drugs in blood being incorporated in the latter two domains during hair synthesis. Drugs in the first two domains would be removed by washing procedures. Use of enzymatic extraction procedures and evaluation of hair for damage from harsh cosmetic treatments might help to separately identify and quantify the drugs incorporated in the second two domains. AIMS/OBJECTIVE:a) Development of an UPLC-MS/MS method for the simultaneous quantification of the following 19 antipsychotic drugs and metabolites in hair: amisulpride, aripiprazole, chlorpromazine, clotiapine, clozapine, desmethylclozapine, desmethylolanzapine, haloperidol, norchlorpromazine, 7-OH-quetiapine, 9-OH-risperidone, olanzapine, pimozine, pimpamperone, quetiapine, risperidone, sertindole, sulpride, and tiapride; b) evaluation of measurement of patient adherence to prescribed medication use, c) determination of the influence of biochemical individuality effects on hair drug content, d) evaluation of relative binding of antipsychotic drugs to protein and to melanin hair structures. METHOD/METHODS:Approximately 10 mg of intact hair were decontaminated with isopropanol and phosphate buffer, and then enzymatically digested overnight with dithiothreitol. After centrifugation, the supernatant digest (protein fraction) was separated from the remaining melanin hair pellet (melanin fraction). Melanin fraction was washed with water, and the drugs were extracted with dimethyl sulfoxide with ball-mill pulverization. Both fractions were purified with solid-phase cation exchange cartridges and injected in the UHPLC-MS/MS system. RESULTS AND DISCUSSION/CONCLUSIONS:Validation of the method was carried out on the protein fraction following international guidelines. The limits of quantification ranged from 1.6-40 pg/mg. The method was applied to 59 head hair samples from prisoners from an antipsychotic compliance study in the criminal justice system in US. The patients were under chlorpromazine, haloperidol, risperidone, olanzapine, or quetiapine multiple antipsychotic treatment, during incarceration. The first head hair centimeter, closest to the scalp, was analyzed. The results were evaluated in relation to the type of hair, colour, hair damage, drug melanin affinity, and prescribed dose. In general, no good correlation between the prescribed dose/concentration in hair was obtained. A wide range of antipsychotic concentrations were observed 'dose mg/day (d); pg/mg protein fraction (A)': chlorpromazine (d:50-400;A:<LOQ->1600) and its metabolite norchlorpromazine (A: <LOQ->1600), haloperidol (d:4-20;A: <LOQ-2902), olanzapine (d:5-20;A: <LOQ-223) and its metabolite desmethylolanzapine (A: <LOQ -136), quetiapine (d:4-400;A: <LOQ -2754) and its metabolite 7-OH-quetiapine (A: <LOQ -1448), risperidone (d:2-20;A: <LOQ->1600) and its metabolite 9-OH-quetiapine (A:<LOQ-296;B). Melanin was found to have a 2- to 85-fold higher drug-binding affinity relative to the protein fraction CONCLUSION: This report describes a different viewpoint method of quantifying the antipsychotics in the melanin and water-inaccessible protein fraction of hair, separately. No correlation between the prescribed dose and the concentrations found in the protein and melanin domains were observed. The results show that hair melanin would have a much higher affinity for the antipsychotic medications than do hair proteins, being influenced mainly by biochemical individuality effects and less by hair colour. Future studies would be of interest using the proposed extraction method applied to hair of different colours.

BACKGROUND:Specialty courts have emerged as a model of care for U.S. youth impacted by commercial sexual exploitation (CSE) to ensure comprehensive service provision. However, there is a lack of published research that documents the extent to which these programs achieve this goal. OBJECTIVE:We sought to understand a specialty juvenile justice court's role in identifying mental health and substance use treatment needs, providing linkages to services, and facilitating stability for youth with histories of CSE. PARTICIPANTS AND SETTING/METHODS:We conducted an exhaustive court file review of the 364 participants in a U.S. based juvenile delinquency specialty court for youth affected by CSE. The observation period spanned 2012-2017. METHODS:The research team systematically transferred data from court files into a secure, electronic database. Descriptive statistics and Chisquared tests were calculated to explore potential associations. RESULTS:Participation in the specialty court for youth impacted by CSE suggests an increase in identification of mental health and substance use needs and linkages and referrals to mental health and substance use treatment services. In addition, there was increased stabilization as indicated by decreased substantiated child welfare allegations, fewer running away episodes, and placements and criminal involvement. CONCLUSIONS:Specialty courts that incorporate a multidisciplinary, trauma-informed approach offer a promising intervention model for meeting the high treatment needs of youth impacted by CSE.

The term justice-involved youth encompasses a broad range of youth. It can include youth who have not been detained and have been placed on probation or diversion programs, as well re-entry populations transitioning out of detention facilities or stated custody and placed on probation or parole. There are more than 1.3 million juvenile arrests per year, and on any given day there are 50,821 youth incarcerated in the United States. Of the 716,000 delinquency cases, probation is court-ordered for approximately half.¹ Even among these youth who are supervised in the community, rates of mental health and substance use disorders are high, with more than two-thirds reporting substance use problems or other mental health disorders.² However, these youth often have a hard time connecting to and staying in treatment,³ and recidivism is high-most commonly for failing to satisfy the myriad (and well intentioned) conditions of their probation.⁴ Dual diagnosis (ie, co-occurring psychiatric and substance use disorders) in justice-involved youth is one of the most significant predictors of recidivism,⁵ and, as such, closing the gap between need and receipt of substance use and mental health treatment for justice-involved youth could potentially offset rates of re-offending into adulthood.⁶ Despite high rates of mental health and substance use disorders among justice-involved adolescents, only 15% of detained youth receive mental health treatment for their condition(s); this number falls to 8% once these youth re-enter the community.⁷ These statistics regarding treatment receipt among justice-involved youth are important to consider not only from a health care perspective but also in terms of public health significance and policy.

Drug users are vastly overrepresented in prison populations. Once inside they face increased risks of acquiring infections such as HIV, hepatitis and TB, and on release they face an elevated risk of fatal overdose. Relapse and recidivism are the norm following release from prison. The implementation of evidence-based drug treatment programmes in prison is rare, yet drug treatment in prison reduces the transmission of infections, recidivism and fatal overdose on release. Recognising the negative returns associated with incarceration, many jurisdictions have begun to consider alternatives such as depenalisation of the personal use of illicit drugs, provision of treatment and social reintegration of drug offenders, and a shift in focus from supply reduction to demand and harm reduction measures in the community and in prison. Women with drug problems are twice as likely to have been imprisoned for a drug offence as incarcerated men. Similarly, HIV prevalence is higher among female inmates. Serious attention should be paid to implementation of non-custodial sentences for women, particularly during pregnancy and those with young children.

Purpose Although the reform of solitary confinement is underway in many jurisdictions around world, isolation remains in widespread use in many jails and prisons. The purpose of this paper is to discuss opportunities for reform in the USA that could also be applied globally. Design/methodology/approach A review of the evidence on solitary confinement policies and practices in the USA to develop recommendations for reform with global application. Findings Focusing on this evidence, the authors argue that solitary confinement is overused and recommend a multi-level approach available to correctional systems worldwide including: immediately limiting solitary confinement to only those cases in which a violent behavioral infraction has been committed for which safety cannot otherwise be achieved, ensuring the briefest terms of isolation needed to achieve legitimate and immediate correctional goals, prohibiting its use entirely for some populations, regularly reviewing all isolated prisoners for as-soon-as-possible return to general population, including the immediate return of those showing mental and physical health risk factors, assisting individuals who are transitioning out of isolation (either to the general population or to the community), and partnering with medical, public health, and criminal justice experts to develop evidence-based alternatives to solitary confinement for nearly all prisoners. Originality/value This paper provides an overview of the evidence supporting an overhaul of solitary confinement policy in the USA and globally where solitary confinement remains in wide use and offers recommendations for immediate steps that can be taken toward achieving evidence-based solitary confinement reform.

A randomized controlled trial was conducted with 600 paroled men, homeless prior to incarceration, to assess varying levels of peer-coach and nurse-partnered interventions on re-arrest at 6 and 12 months. Findings revealed that positive predictors of re-arrest at 12 months included having received social support from drug users and non-drug users, as well as having used marijuana at least once a week prior to their most recent incarceration. In terms of protective factors, those who participated in a substance abuse program contract within a residential drug treatment program or spent 90 days or greater in a residential drug treatment program were less likely to have been re-arrested within 12 months.
