Review
Children and adolescents with psychopathic traits show deficits in emotion recognition, but there is no consensus as to the extent of their generalizability or about the variables that may be moderating the process. The present Systematic Review brings together the existing scientific corpus on the subject and attempts to answer these questions through an exhaustive review of the existing literature according to PRISMA 2020 statement. Results confirmed the existence of pervasive deficits in emotion recognition and, more specifically, on distress emotions (e.g., fear), a deficit that transcends all modalities of emotion presentation and all emotional stimuli used. Moreover, they supported the key role of attention to relevant areas that provide emotional cues (e.g., eye-region) and point out differences according to the presence of disruptive behavior and based on the psychopathy dimension examined. This evidence could advance the current knowledge on developmental models of psychopathic traits. Yet, homogenization of the conditions of research in this area should be prioritized to be able to draw more robust and generalizable conclusions.

The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), published in 2013, includes an alternative model of personality disorders (AMPD) focusing on a maladaptive trait model utilized to diagnose several personality disorders. Borderline personality disorder (BPD) and antisocial personality disorder (ASPD) are two conditions categorized by AMPD that exhibit high rates of violence and aggression. Several of the traits outlined in the AMPD, including hostility, impulsivity, risk-taking, and callousness, have been previously linked to aggression in BPD and ASPD. However, to the best of our knowledge, there has never been a synthesis of neuroimaging studies that have investigated links between these traits and aggression in BPD and ASPD. To overcome this gap, we conducted a systematic review under the PRISMA framework to locate neuroimaging articles published since the release of AMPD linking trait anger/hostility, impulsivity, risk-taking, and callousness to aggression in BPD and ASPD. Key findings included the following: i) anger/hostility, associated with alterations in the interplay between prefrontal and subcortical regions (primarily the amygdala), may be a common factor explaining aggressive reactions to response to interpersonal threat or provocation; ii) alterations of fronto-temporal-limbic regions and serotonergic and endocannabinoid signaling systems may link impulsivity to aggression in BPD and ASPD; iii) weaker cortico-striatal connectivity could relate to greater risk taking and greater proclivity for violence. Insufficient evidence from neuroimaging articles was discerned to describe a relationship between callousness and aggression. Overall, results of this review reveal a relative paucity of neuroimaging studies examining AMPD traits relevant to aggression in BPD and ASPD. In addition to encouraging further investigation of neuroimaging markers of AMPD traits linked to aggression, we recommend multi-methodological designs, including the incorporation of other biomarkers, such as hormones and indices of physiological arousal, to fully expand our understanding of aggression in BPD and ASPD.

Review
OBJECTIVE
Conduct a systematic review concerning the literature that reflects whether the callous and unemotional traits present in childhood and/or adolescence are precursors in the development of female psychopathy in adulthood.
MATERIALS AND METHODS
A systematic review involved consulting three databases-EBSCO, the Web of Science, and PubMed-for peer-reviewed and quantitative studies within the period 2000-2023. Nine articles with quality of three and above were included.
RESULTS
The presence of callous and unemotional traits designates a group of youth that show characteristics associated with psychopathy, specifically when predicting a more severe and chronic pattern of antisocial behaviour. Children with high rates of callous and unemotional traits, who show symptoms of attention deficit hyperactivity disorder in combination with severe conduct problems, are most likely to show features associated with psychopathy. The multidimensional psychopathy construct is considered a better predictor of future and stable antisocial behaviour than the callous and unemotional traits alone model.
CONCLUSIONS
According to the studies selected, the callous and unemotional traits in childhood seem to be precursors of female psychopathy in adulthood, but only because of the way they seem to enhance conduct problems, disruptive behaviour disorders, and, as a possible outcome, delinquency and antisocial traits, which may be precursors of future psychopathy.

Meta-Analysis
Thigmotaxis is an innate predator avoidance behaviour of rodents. To gain insight into how injury and disease models, and analgesic drug treatments affect thigmotaxis, we performed a systematic review and meta-analysis of studies that assessed thigmotaxis in the open field test. Systematic searches were conducted of 3 databases in October 2020, March and August 2022. Study design characteristics and experimental data were extracted and analysed using a random-effects meta-analysis. We also assessed the correlation between thigmotaxis and stimulus-evoked limb withdrawal. This review included the meta-analysis of 165 studies We report thigmotaxis was increased in injury and disease models associated with persistent pain and this increase was attenuated by analgesic drug treatments in both rat and mouse experiments. Its usefulness, however, may be limited in certain injury and disease models because our analysis suggested that thigmotaxis may be associated with the locomotor function. We also conducted subgroup analyses and meta-regression, but our findings on sources of heterogeneity are inconclusive because analyses were limited by insufficient available data. It was difficult to assess internal validity because reporting of methodological quality measures was poor, therefore, the studies have an unclear risk of bias. The correlation between time in the centre (type of a thigmotactic metric) and types of stimulus-evoked limb withdrawal was inconsistent. Therefore, stimulus-evoked and ethologically relevant behavioural paradigms should be viewed as two separate entities as they are conceptually and methodologically different from each other.

Review
: Higher level of aggression and antisocial behavior have been found in the period following head trauma. These changes are attributable to specific brain alterations that generally involved frontal lobe, insula and limbic system. A descriptive review was conducted on the specificity of aggressive behavior in relation to traumatic brain injury by evaluating numerous variables, focusing on age at the time of trauma and neuroimaging studies. : We searched on PubMed and the Web of Science databases to screen references of included studies and review articles for additional citations. From an initial 738 publications, only 27 met the search criteria of describing the relationship between aggression, brain alterations and traumatic brain injury. : These findings showed that traumatic brain injury (TBI) is related to changes in behavior, personality and mood. : The development of aggressive and criminal behavior is associated with multiple factors, including the etiology of injury, environmental, psychosocial and personality factors and age at the time of trauma.

Prior research has demonstrated an association between lead exposure and criminal behavior at the population-level, however studies exploring the effect of lead exposure on criminal behavior at the individual-level have not been reviewed systematically. The intent of this study is to complete a systematic review of all studies assessing individual-level exposures to lead and the outcomes of crime and antisocial behavior traits. We included peer reviewed studies that were published prior to August 2022 and were classified as cohort, cross-sectional, or case-control. Studies measuring the outcomes of crime, delinquency, violence, or aggression were included. The following databases were searched using a standardized search strategy: ProQuest Environmental Science Database, PubMed, ToxNet and the Public Affairs Information Service (PAIS). Seventeen manuscripts met our inclusion criteria. Blood lead was measured in 12 studies, bone lead in 3 studies, and dentine lead levels in 2 studies. This systematic review identified a wide range of diverse outcomes between exposure to lead at multiple windows of development and later delinquent, criminal and antisocial behavior. A review of all potential confounding variables included within each study was made, with inclusion of relevant confounders into the risk of bias tool. There is limited data at the individual level on the effects of prenatal, childhood, and adolescent lead exposure and later criminal behavior and more evidence is necessary to evaluate the magnitude of the associations seen in this review. Our review, in conjunction with the available biological evidence, suggests that an excess risk for criminal behavior in adulthood exists when an individual is exposed to lead in utero or in the early years of childhood. The authors report no conflict of interest and no funding source. Clinical trial registration: PROSPERO ID: CRD42021268379.

Review
Improving safety and health for correctional workers and people who are incarcerated are widespread yet separate initiatives. Correctional workers and people who are incarcerated experience similar challenges involved with poor workplaces and living conditions, including mental health crises, violence, stress, and chronic health issues, and the available resources lack integration with respect to safety and health promotion. This scoping review sought to contribute to an integrated approach for correctional system safety and health resources and identify studies of correctional resources that address health promotion among correctional workers and people who are incarcerated. Guided by PRISMA, a search of gray literature, also termed peer-reviewed literature, published between 2013-2023 ( = 2545) was completed, and 16 articles were identified. Resources primarily targeted individual and interpersonal levels. At every level of intervention, resources improved the environment for both workers and those incarcerated, with trends of less conflict, more positive behaviors, and improved relations, access to care, and feelings of safety. The corrections environment is impacted by changes from both workers and people who are incarcerated and should be examined using a holistic approach. Future health and safety resources should target the larger correctional environment by utilizing practices, policies, and procedures to improve safety and health for incarcerated people and workers.

INTRODUCTION
Mental health care provided to offenders with psychiatric problems in forensic settings mainly consists of verbal oriented treatments. In addition, experience-based therapies are used such as (creative) arts therapies: (visual) art therapy, music therapy, drama therapy and dance (movement) therapy. There are indications for effectiveness of arts therapies, but a systematic overview of effect studies of all arts therapies in forensic care is lacking.
METHODS
First, we performed a systematic review. Second, Thematic Analysis was used to synthesize the qualitative narrative results and define the hypothesized mechanisms of change. Third, we performed a meta-analysis to investigate the effects of arts therapies in reducing psychosocial problems of offenders. Twenty-three studies were included in the review. Quality and risk of bias was assessed using EPHPP (Effective Public Health Practice Project).
RESULTS
The included studies were heterogeneous in type of outcome measures and intervention characteristics. Synthesis of mechanisms of change involved in the methodical use of the arts in arts therapies resulted in a description of regulatory processes which are stimulated in arts therapies: perceptive awareness (interoceptive and exteroceptive), the regulation of emotions, stress, impulses, cognitions, social regulation, and self-expression. These processes play a role in developing prevention, coping and self-management skills. Eighteen studies were included in the meta-analyses (11 RCTs/CCTs; 7 pre-post studies). The meta-analyses indicated significant effects on both risk factors (psychiatric symptoms and addiction) and protective factors for criminal behavior (social functioning and psychological functioning). Effects on criminal and/or antisocial behavior were not significant, but this outcome measure was scarcely used among the studies.
DISCUSSION
The analyses in this study should be considered explorative. More research is needed to gain more solid conclusions about effectiveness and mechanisms of change of arts therapies in forensic institutions. However, the results of this first systematic review, synthesis of mechanisms and meta-analysis in this field are promising and show effects of arts therapies on risk and protective factors in individuals in forensic institutions.

Meta-Analysis Review
This meta-analysis aims to examine the relationship between psychopathic traits and theory of mind (ToM), which is classically and broadly defined as competency in representing and attributing mental states such as emotions, intentions, and beliefs to others. Our search strategy gathered 142 effect sizes from 42 studies, with a total sample size of 7463 participants. Random effects models were used to analyze the data. Our findings suggested that psychopathic traits are associated with impaired ToM task performance. This relationship was not moderated by factors such as age, population, psychopathy measurement (self-report versus clinical checklist) or conceptualization, or ToM task type (cognitive versus affective). The effect also remained significant after excluding tasks that did not require the participant to 1) mentalize or 2) differentiate between self and other perspectives. However, interpersonal/affective traits were associated with a more pronounced impairment in ToM task performance compared to lifestyle/antisocial traits. Future research should investigate the effects of distinct psychopathy facets that will allow for a more precise understanding of the social-cognitive bases of relevant clinical presentations in psychopathy.

Meta-Analysis Review
The aim of this systematic review and meta-analysis was to investigate the diagnostic, the dimensional mean-level, and rank-order stability of personality disorders (PDs) and PD criteria over time. EMBASE, PsycInfo, PubMed, and Web of Science were searched for peer-reviewed studies published in either English, German, or French between the first publication of the third edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-III) in 1980 and December 20, 2022. Inclusion criteria were a prospective longitudinal study design, assessing the stability of PDs or PD criteria over at least two measurement occasions at least one month apart, and using the same assessment at baseline and follow-up. Effect sizes included proportion of enduring cases (i.e., diagnostic stability), test-retest correlations (i.e., dimensional rank-order stability), and within-group standardized mean differences (i.e., dimensional mean-level stability), based on the first and last available measurement occasion. From an initial pool of 1473 studies, 40 were included in our analyses, covering 38,432 participants. 56.7% maintained the diagnosis of any PD, and 45.2% maintained the diagnosis of borderline PD over time. Findings on the dimensional mean-level stability indicate that most PD criteria significantly decreased from baseline to follow-up, except for antisocial, obsessive-compulsive, and schizoid PD criteria. Findings on the dimensional rank-order stability suggested moderate estimates, except for antisocial PD criteria, which were found to be high. Findings indicated that both PDs and PD criteria were only moderately stable, although between study heterogeneity was high, and stability itself depended on several methodological factors.
