Importance: People living with psychosis experience excess premature mortality and are overrepresented in criminal legal systems, but little is known about mortality associated with criminal sanctions or diversion in this population., Objective: To examine associations of different types of recent (past 2 years) criminal sanction, including court diversion, with mortality among people with psychosis., Design, Setting, and Participants: This population-based, retrospective, data-linkage cohort study was conducted using 6 routinely collected administrative data collections from New South Wales, Australia, relating to health, court proceedings, imprisonment, and mortality. Participants (adults aged ≥18 years hospitalized for psychotic disorders) entered observation at the time of discharge from their first psychosis-related hospital admission (or their 18th birthday if aged <18 years) between July 2001 and November 2017 and were followed-up until May 2019. Data were analyzed between February 2023 and April 2024., Exposures: Recent (past 2 years) criminal sanction type, a time-varying variable with 5 categories: no recent criminal sanction, recent mental health court diversion, recent community sanction, current imprisonment, and recent prior imprisonment (ie, recent prison release)., Main Outcomes and Measures: Causes of death were described, and age- and sex-specific mortality rates by recent criminal sanction type were calculated. In those younger than 65 years, Cox regression was used to examine associations of all-cause and external-cause mortality with recent criminal sanction type, adjusting for sociodemographic, health-related, and offense-related confounders., Results: The cohort included 83 071 persons (35 791 female [43.1%]; 21 208 aged 25-34 years [25.5%]; median [IQR] follow-up, 9.5 [4.8-14.2] years), of whom 25 824 (31.1%) received a criminal sanction. There were 11 355 deaths. In those aged younger than 65 years, recent mental health court diversion, community sanctions, and prior imprisonment were associated with increased hazards of all-cause and external-cause mortality compared with no recent sanction, with the largest adjusted hazard ratios (aHRs) observed for recent prior imprisonment (all-cause mortality: aHR, 1.69; 95% CI, 1.50-1.91; external-cause mortality: aHR, 2.64; 95% CI, 2.27-3.06)., Conclusions and Relevance: In this cohort study of people with psychosis, recent criminal sanctions were associated with increased mortality irrespective of sanction type. These findings suggest that future research should develop strategies to improve health and safety in people with psychosis who have criminal legal system contact.

Introduction: Considerable evidence supports an association between poor impulse control (impulsivity) and violent crime. Furthermore, impulsivity and aggression has been associated with reduced levels of serotonergic activity in the brain. Selective serotonin reuptake inhibitors (SSRIs) are a class of anti-depressants that aim to regulate brain serotonin concentrations. Several small studies in psychiatric populations have administered SSRIs to impulsive--aggressive individuals, resulting in reduced impulsivity, anger, aggression and depression. However, no clinical trial has been undertaken in a criminal justice population. This protocol describes the design and implementation of the first systematic study of the potential benefits of SSRIs in impulsive---violent offenders who are at high risk of reoffending., Methods and Analysis: A randomised, double-blinded, multicentre trial to test the clinical efficacy of an SSRI, sertraline hydrochloride, compared with placebo on recidivism and behavioural measures (including impulsivity, anger, aggression, depression and self-reported offending) over 12 months. 460 participants with histories of violence and screening positive for impulsivity are recruited at several local courts and correctional service offices in New South Wales, Australia., Ethics and Dissemination: Results will be submitted for publication in a peer-reviewed journal. Possible implications of the effectiveness of this pharmacological intervention include economic benefits of reducing prison costs and societal benefits of improving safety. This study has received ethical approval from the University of New South Wales, Aboriginal Health & Medical Research Council, Corrective Services NSW and the NSW Justice Health and Forensic Mental Health Network., Trial Registration Number: ACTRN12613000442707., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

Convincing evidence exists for the positive effect of an improvement in diet quality on age-related cognitive decline, in part due to dietary fatty acid intake. A cross-sectional analysis of data from the Hunter Community Study (HCS) ( n = 2750) was conducted comparing dietary data from a validated Food Frequency Questionnaire (FFQ) with validated cognitive performance measures, Audio Recorded Cognitive Screen (ARCS) and Mini Mental State Examination (MMSE). Adjusted linear regression analysis found statistically significant associations between dietary intake of total n-6 fatty acids (FA), but no other FAs, and better cognitive performance as measured by the ARCS (RC = 0.0043; p = 0.0004; R ² = 0.0084). Multivariate regression analyses of n-6 FA intakes in quartiles showed that, compared with the lowest quartile (179.8⁻1150.3 mg), those in the highest quartile (2315.0⁻7449.4 mg) had a total ARCS score 2.1 units greater (RC = 10.60466; p = 0.006; R ² = 0.0081). Furthermore, when n-6 FA intake was tested against each of the ARCS domains, statistically significant associations were observed for the Fluency (RC = 0.0011432; p = 0.007; R ² = 0.0057), Visual (RC = 0.0009889; p = 0.034; R ² = 0.0050), Language (RC = 0.0010651; p = 0.047; R ² = 0.0068) and Attention (RC = 0.0011605; p = 0.017; R ² = 0.0099) domains, yet there was no association with Memory (RC = -0.000064; p = 0.889; R ² = 0.0083). No statistically significant associations were observed between FA intakes and MMSE. A higher intake of total n-6 FA, but not other types of FA, was associated with better cognitive performance among a representative sample of older aged Australian adults.

Primary Objective: To establish the prevalence, severity, recurrence and sequelae of past traumatic brain injury (TBI) among individuals recently received into custody., Research Design: Cross-sectional random sample of men recently received into the New South Wales' (NSW) criminal justice system., Procedures: Participants were screened for a history of TBI including the injury setting, severity, treatment and sequelae of up to five separate TBI episodes., Outcomes and Results: Of 200 study participants, 82% endorsed a history of at least one TBI of any severity and 65% a history of TBI with a loss of consciousness (LOC). Multiple past TBIs were common, as were ongoing sequelae. Treatment for the TBI was more common among those TBIs with a LOC compared with no LOC (66% vs. 39%)., Conclusions: Among individuals entering the criminal justice system, past TBI is common and often associated with ongoing neuropsychiatric and social sequelae. Screening for TBI at the point of reception may be warranted to better understand and treat those with ongoing neuropsychiatric sequelae arising from the TBI.
