High levels of drug dependence have been observed in the prison population globally, and the sharing of injecting drug equipment in prisons has contributed to higher prevalence of bloodborne diseases in prisoners than in the general population. Few prison needle and syringe programs (PNSPs) exist. We conducted a systematic review to assess evidence regarding health outcomes of PNSPs. We searched peer-reviewed databases for data relating to needle and syringe programs in prisons. The search methodology was conducted in accordance with accepted guidelines. Five studies met review inclusion criteria, and all presented evidence associating PNSPs with one or more health benefits, but the strength of the evidence was low. The outcomes for which the studies collectively demonstrated the strongest evidence were prevention of human immunodeficiency virus and viral hepatitis. Few negative consequences from PNSPs were observed, consistent with previous evidence assessments. More research is needed on PNSP effectiveness, and innovative study designs are needed to overcome methodological limitations of previous research. Until stronger evidence becomes available, policymakers are urged to recognize that not implementing PNSPs has the potential to cause considerable harm, in light of what is currently known about the risks and benefits of needle and syringe programs and PNSPs and about the high prevalence of human immunodeficiency virus and viral hepatitis in prisons.

Polycationic superparamagnetic nanoparticles (∼150-250 nm) were evaluated as virucidal agents. The particles possess a core-shell structure, with cores consisting of magnetite clusters and shells of functional silica covalently bound to poly(hexamethylene biguanide) (PHMBG), polyethyleneimine (PEI), or PEI terminated with aziridine moieties. Aziridine was conjugated to the PEI shell through cationic ring-opening polymerization. The nanometric core-shell particles functionalized with biguanide or aziridine moieties are able to bind and inactivate bacteriophage MS2, herpes simplex virus HSV-1, nonenveloped infectious pancreatic necrosis virus (IPNV), and enveloped viral hemorrhagic septicaemia virus (VHSV). The virus-particle complexes can be efficiently removed from the aqueous milieu by simple magnetocollection.

IMPORTANCEThe ongoing overdose crisis continues to adversely affect adolescents and young adults (AYAs) and has led to numerous preventable deaths. Medications for opioid use disorder (MOUD), such as methadone, buprenorphine, and naltrexone, have the potential to reduce opioid use and associated harms; however, there are concerns that AYAs lack access to these potentially life-saving medications.OBJECTIVE To systematically review peer-reviewed literature on MOUD access and associated factors to synthesize strategies that can improve MOUD access for AYAs who use opioids. EVIDENCE REVIEWThe MEDLINE, Embase, PsycINFO, CINAHL, Sociological Abstracts, Web of Science, and Global Dissertations & Theses databases were searched from database inception until May 3, 2021. English, French, Russian, or Spanish peer-reviewed studies that evaluated the availability, prescription receipt, or initiation of MOUD were eligible for inclusion.FINDINGS This systematic review identified 37 cohort (n = 17), cross-sectional (n = 15), and qualitative (n = 5) studies that accounted for 179 785 AYAs (mean [SD] age, 24.4 [3.9] years; 148 779 [85%] were female; 67 771 [84%] were White) and examined access to methadone (30 studies), buprenorphine (26 studies), and naltrexone (10 studies). Findings reinforce concerns that AYAs were less likely to access MOUD and suggest that adolescents were more likely to receive naltrexone or buprenorphine-naloxone, which have a lower potential for abuse, in comparison with young adults. This review also identified other factors that were associated with MOUD access, including criminal justice involvement, residing in the US South, living in a limited-income area, Black race, and Hispanic or Latino ethnicity, suggesting ways in which treatment services may be improved to increase MOUD access and meet the treatment goals of AYAs.CONCLUSION AND RELEVANCE This systematic review found gaps in MOUD access between AYAs and non-AYA populations in addition to differences in MOUD access between adolescents and young adults. Considering that existing clinical guidelines recommend the use of MOUD among AYAs, and in light of the increasing number of opioid toxicity deaths, there is a need to improve MOUD access among AYAs by reducing barriers to MOUD and providing AYAs with a continuum of health and social supports alongside MOUD. Future research into ways to encourage MOUD uptake among AYAs may improve the treatment and health outcomes for this population.
