BACKGROUND: Adverse childhood events (ACEs), psychopathy, and self-harming behaviours are prevalent among individuals in the forensic psychiatry system. While existing literature suggests that ACEs, self-harm, and psychopathy are interrelated, little is known about the interplay of psychopathic traits in this relationship. The present study aimed to determine the mediating role of psychopathy in the relationship between ACEs and self-harming behaviours in forensic patients. METHODS: This was a retrospective study of patients under the Ontario Review Board (ORB) between 2014 and 2015. In the analysis, we included patients with complete data on ACEs, self-harming behaviours, and a Psychopathy Checklist-Revised (PCL-R) score - a measure of psychopathic traits and their severity conducted during the reporting period. Mediation analysis was based on the Baron and Kenny approach, and sensitivity analysis was performed based on the types of ACEs. RESULTS: ​​​The sample population (n = 593) was made up of adults, with a mean age of 41.21 (± 12.35) years and were predominantly males (92.37%). While there was a partial mediating effect of psychopathy on the relationship between ACEs and incidents of self-harming behaviours in the past year, the mediation was complete in the relationship between ACEs and a lifetime history of self-harming behaviours. Following sensitivity analysis based on the types of ACE, the mediating effects were more attributed to specific ACEs, especially having experienced child abuse or having an incarcerated household member before 18 years. CONCLUSION: Among forensic patients in Ontario, psychopathy mediates​ ​the relationship between experiencing ACEs and engaging in self-harming behaviours. Effective intervention to mitigate self-harming behaviours in this population should consider the potential role of psychopathy, especially among individuals who have experienced ACEs involving a history of child abuse and a family who was incarcerated.

BACKGROUND: In Canada, ensuring public safety, and the safety and well-being of accused individuals under the jurisdiction of the provincial review board are very important. While previous studies have reported a significant risk of self-harming behaviors (non-suicidal self-injury and suicide attempt) in forensic psychiatric settings, no large population study has assessed any relationship between forensic system-related factors and self-harming behaviors. A better understanding of these factors can help clinicians implement protective measures to mitigate self-harming behaviors or actions. METHODS: Using the Ontario Review Board (ORB) database covering 2014-2015 period (n = 1211, mean age = 42.5 ± 13.37 years, males = 86.1%), we analyzed the prevalence and factors associated with self-harming behaviors, emphasizing the characterization of the forensic system-related factors (ORB status, legal status, type of offense, previous criminal history, and victim relationship). The relationships between the forensic system-related factors and self-harming behaviors were explored using five separate logistic regression models, controlling for clinical and sociodemographic characteristics. RESULTS: Approximately 4% of the individuals in the forensic system over the study period engaged in self-harming behaviors Among the studied patients, individuals determined to be unfit to stand trial and inpatients were significantly more likely to have self-harming behaviors. There was no significant relationship between the type of offence, victim relationship, and previous criminal history with self-harming behavior. CONCLUSION: Forensic psychiatry inpatients should have close observation, screening, monitoring, and individual tailored management strategies for self-harming behaviors. The findings of this study indicate that forensic system-related factors, especially those that pertain to the status of individuals in the forensic system (i.e., unfit to stand trial and being an inpatient) are more responsible for self-harming behaviors among forensic patients in Ontario.

BACKGROUND: Electroretinogram (ERG) is one of the tools used to investigate the electrophysiological underpinnings of mental health illnesses and major clinical phenomena (e.g., suicide) to improve their diagnosis and care. While multiple studies have reported specific ERG changes among individuals with suicidal behaviors, we know of no review that has been done to characterize their findings to inform future research. METHODS: This review included available literature concerning ERG and suicidal behaviors. The paper's first section briefly overviews the theoretical basis of ERG and neurotransmitters involved in suicidal behaviors. The second section describes the findings of a review of studies reporting ERG findings among individuals with suicidal behaviors. RESULTS: Most reviewed studies reported normal amplitude and implicit time of the a-waves, but the latency in individuals with suicidal behaviors was lower than normal. Additionally, the b-waves amplitude was reduced, but the implicit time and latency were increased. The b-a amplitude ratio and oscillatory potential were decreased. CONCLUSION: Despite identifying certain ERG correlates with suicidal behaviors in the existing studies, there is a need for adequately powered and methodologically robust studies to advance clinical translation.

BACKGROUND: Food insecurity has become a growing burden within a global context where climate change, catastrophes, wars, and insurgencies are increasingly prevalent. Several studies have reported an association between suicidal behaviors (i.e., suicide ideation, plans, and attempts) and food insecurity. This meta-analytic review synthesized the available literature to determine the pooled prevalence of suicidal behaviors among individuals experiencing food insecurity, and examined the strength of their association. METHODS: Databases (Ovid, PubMed, Web of Science, and CINAHL) were searched from inception to July 2022 using appropriate search terms. Eligible studies reporting the number/prevalence of suicidal behaviors among individuals experiencing food insecurity or the association between food insecurity and suicidal behaviors were included. The pooled prevalence of suicidal behaviors was determined using the random-effects model. The review was registered with PROSPERO (CRD42022352858). RESULTS: A total of 47 studies comprising 75,346 individuals having experienced food insecurity were included. The pooled prevalence was 22.3 % for suicide ideation (95 % CI: 14.7-29.9; I2 = 99.6 %, p < 0.001, k = 18), 18.1 % for suicide plans (95 % CI: 7.0-29.1; I2 = 99.6 %, p < 0.001, k = 4), 17.2 % for suicide attempts (95 % CI: 9.6-24.8; I2 = 99.9 %, p < 0.001, k = 12), and 4.6 % for unspecified suicidal behavior (95 % CI: 2.8-6.4; I2 = 85.5 %, p < 0.001, k = 5). There was a positive relationship between experiencing food insecurity and (i) suicide ideation (aOR = 1.049 [95 % CI: 1.046-1.052; I2 = 99.6 %, p < 0.001, k = 31]), (ii) suicide plans (aOR = 1.480 [95 % CI: 1.465-1.496; I2 = 99.1 %, p < 0.001, k = 5]), and (iii) unspecified suicide behaviors (aOR = 1.133 [95 % CI: 1.052-1.219; I2 = 53.0 %, p = 0.047, k = 6]). However, a negative relationship was observed between experiencing food insecurity and suicide attempts (aOR = 0.622 [95 % CI: 0.617-0.627; I2 = 98.8 %, p < 0.001, k = 15]). The continent and the countries income status where the study was conducted were the common causes of heterogeneity of the differences in the odds of the relationships between experiencing food insecurity and suicidal behaviors - with North America and high-income countries (HICs) having higher odds. For suicide attempts, all non HICs had a negative relationship with food insecurity. LIMITATIONS: There was significant heterogeneity among the included studies. CONCLUSION: There is a high prevalence of suicidal behaviors among individuals experiencing food insecurity. Initiatives to reduce food insecurity would likely be beneficial for mental wellbeing and to mitigate the risk of suicidal behaviors among population experiencing food insecurity. The paradoxical finding of suicide attempts having a negative relationship with food insecurity warrants further research.

BACKGROUND: Forensic-correctional psychiatric services are an important component of the public mental health services that provide care to offenders with mental illness in the criminal justice system and conduct psycho-legal assessments. Although forensic-correctional psychiatric services have evolved in Abu Dhabi, more work is needed in providing adequate mental health care for offenders. METHODS: This study provides a situational analysis of forensic-correctional psychiatric services in Abu Dhabi. We included a descriptive analysis of the data collected on service users admitted for psycho-legal assessments and treatment in the forensic-correctional units and those reviewed in the medical board units for issuing court reports. The study spanned the period between January 2019 to October 2020. RESULTS: A total of 398 males were included in the study. The participants' mean age was 35.3 (SD 9.27) years and were predominantly single, unemployed and high school graduates. The most prevalent diagnosis was schizophrenia spectrum disorder, (n=129, 31.6%). The mean length of stay in the forensic-correctional unit was 11.07 days. As many as 82.4% of the participants were referred for evaluation. The most common type of crime was categorized as "abnormal behaviour" under the code of practice number 511 of the list of crimes as per the general prosecutor of the United Arab Emirates followed by violence. CONCLUSION: Considering the level of demand for services and the limited number of forensic-correctional health professionals, there is a need for more resources to develop expertise, clinical services and infrastructures to expand the practice of forensic-correctional psychiatry. The creation of a universal database for all forensic-correctional psychiatric services is needed to better understand the unmet mental health needs. An additional investment of resources for research to inform mental health policy, laws and practice is indicated. Optimally, the lessons highlighted in this study can guide action plans for improving forensic-correctional mental health services in comparable settings.

While serious concerns are often raised when patients abscond or leave unauthorized from psychiatric services, there is limited knowledge about absconsion in forensic psychiatric services. Following the preferred reporting items for systematic reviews and meta-analyses guideline, we searched Medline/PubMed, PsycINFO, EMBASE, CINAHL, Scopus, and Web of Science through May 2020 for eligible reports on absconsion in forensic patients with no language limits. The search string combined terms for absconsion, forensic patients, and psychiatry in various permutations. This was supplemented by snowball searching for additional studies. Of the 565 articles screened, 25 eligible studies, including two interventional, seven cross-sectional, and 16 case-controlled studies spanning five decades were included. Absconsion and re-absconsion rates ranged from 0.2% to 54.4% and 15% to 71%, respectively, albeit higher rates trended with less secure psychiatric units. Previous absconsion, aggression, substance use, high Historical Clinical Risk Management-20 score, anti-sociality, psychiatric symptoms, sexual offending, and poor treatment adherence were the factors reported with a degree of predictive value for absconsion. However, the construct of absconsion was heterogeneous in the included studies and the quality of evidence on the predictors of absconsion was limited. Serious risky behaviors including re-offending, violence, self-harm, suicide, rape, and manslaughter were perpetrated by patients during unauthorized leave. Nevertheless, the rates of re-offending were generally low in the included studies (highest recidivism rate = 0.11). There is need for standardized assessment and documentation of absconsion to improve risk analysis and management. Furthermore, it is necessary to develop a structured guideline for defining absconsion, and to create a protocol that operationalizes all absconsion-related behaviors/events to promote reliable assessment and comparative analysis in future studies.

Child pornography involves the realisation of deviant fantasies with very specific characteristics with regard to its content and use and therefore the legal action needed to deal with it. The internet has facilitated its dissemination and access and complicates the issue but we need to be able to identify and track people who use illegal pornography. This paper is based on a review of the literature and presents some criminological characteristics of child pornography on the internet.

This review aims to consolidate the available information on use of electroretinography as a diagnostic tool in psychiatry. The electroretinogram (ERG) has been found to have diagnostic utility in cocaine withdrawal (reduced light-adapted b-wave response), major depressive disorder (reduced contrast gain in pattern ERG), and schizophrenia (reduced a- and b-wave amplitudes). This review examines these findings as well as the applicability of ERG to substance use disorder, Alzheimer's disease, autism spectrum disorder, panic disorder, eating disorders, attention deficit hyperactivity disorder, and medication use. While there have been promising results, current research suffers from a lack of specificity. Further research that quantifies anomalies in ERG present in psychiatric illness is needed.

Psychiatric symptoms resulting from Multiple Sclerosis (MS) itself or its treatment are well known. However, the relationship between psychotic episodes and Multiple Sclerosis remains debated. In this paper, we present the case of a woman who developed a chronic psychotic disorder a few months after the onset of MS. We describe the process which led us to make the diagnosis of Psychotic Disorder due to Medical Condition (Multiple Sclerosis). Because her criminal charges brought significant attention to her case, we also address the difficulty in treating a neurological condition with psychiatric features within the forensic context. Moreover, one of the main concerns of the patient was that Lyme Disease was the correct diagnosis as opposed to MS. We also report the difficulty of treating and initiating successful follow-up for a patient whose paranoia is enabled by the opinions of certain health advocacy groups.

Involuntary hospitalisation has been legal in France since 1838. The first reform took place in 1990. However, critics postulated that this first reform did not adequately respect the rights of patients. Consequently, further reforms were introduced in 1990. In 2011 further reforms rendered involuntary hospitalisation consistent with European requirements, introducing systematic control by the Juge des Libertés et de la Détention (Judge of Freedoms and Detention) for each patient hospitalised without consent. The purpose of this article is to provide a qualitative description of the evolution of the legal concerns surrounding involuntary hospitalisation in France.

The manifestations of disorders of the mind may play a role in the occurrence of criminal behavior. In the majority of the cases, the presence of a psychiatric disorder is cited as the reason that an individual was not fully aware of his behavior. However, other conditions, such as seizure disorders or hypoglycemia, have also been linked to an inability to understand the nature and consequences of one's actions. On occasion, these situations can be explained by a state of automatism that may be described as insane or noninsane. In this article, we describe the case of a 77-year-old man, suffering from Parkinson's disease, where the issue of criminal responsibility associated with incapacity of the mind secondary to medication misuse was raised. We elaborate on the thinking behind this opinion and the implications according to Canadian law. Although the legal outcome of this case is specific to our jurisdiction, the clinical implication may be common to any patient suffering from a similar condition and may inform physicians, families, and lawyers.

Strychnine-related death has been described since the 19th century. This alkaloid was discovered in 1818. Historically, strychnine was used by the South-East Asian autochthones on their arrows. However, its production was modified by legislation, which was used to protect people against accidental intoxications. Here, we present the case of a 69-year-old man who was found dead at home. During the autopsy, we found a blue substance in the stomach. Toxicological analysis measured strychnine at 0.29 µg/mL in the blood sample, which is a relatively low level in comparison with the results given in the literature. However, histologic examination and toxicological findings permitted the conclusion of strychnine poisoning.

A suicide pact is the decision of two or more people to die together. This event is rare. The majority of suicide pacts victims are married, socially isolated, with a serious physical illness in one or both partners. We performed a retrospective study of all cases of suicide pacts leading to death between January 1, 2003 and December 31, 2010 referred to the Forensic Medicine Department of Tours (France). Six cases were recorded as suicide pacts. Firearms were the preferred means of death. Five suicide notes were discovered. For some cases, it was difficult to establish whether death was the result of a suicide pact or of a homicide-suicide without the consent of the victim. An objective element, such as a suicide note and motive, is required to prove that a suicide pact is involved. The prevalence of mental disorders is hard to assess. In France, psychological autopsies are not performed in such cases, as the investigation is usually very sparse after the death of both individuals.

Child pornography is a form of child sexual exploitation which has been modified by the use of the Internet. The use of child pornography does not necessarily lead to actual child abuse. Victims of child pornography can be classified as direct victims, who have been sexually abused, and indirect victims, who receive images to groom them for actual abuse in the future. Based on a review of the literature, we present the psychopathological characteristics of child pornographers and their victims.
