There have been fairly limited reports in the literature of assaults on residents in psychiatric facilities. Assaults on residents and staff tend to be underreported and, for a variety of reasons, not adequately dealt with by the administration. For this reason, security in psychiatric facilities may be lacking in many instances. In order to prepare a position paper of guidelines specifying minimum security requirements for psychiatric facilities in Canada, the Residents' Section of the Canadian Psychiatric Association gathered data on this issue from psychiatric residents. We present the results of a questionnaire sent to all psychiatric residents who are members of the Canadian Psychiatric Association. Results indicate that 40.2% of residents have been assaulted at least once. We present some interesting findings that relate to the residents' perception of their training and the appropriateness of the facilities for assessing patients. Requests for improved security were made by 36.9% of the residents, but only 22.9% of this group found the response by acceptable. Some of the residents' explanations for the assaults suggest interesting dynamics. These and other findings suggest an urgent need to address this issue.

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.

We aimed to summarize the available evidence on cerebral blood flow (CBF) changes in normal aging and common cognitive disorders. We searched PubMed for studies on CBF changes in normal aging and cognitive disorders up to 1 January 2019. We summarized the milestones in the history of CBF assessment and reviewed the current evidence on the association between CBF and cognitive changes in normal aging, vascular cognitive impairment (VCI) and Alzheimer’s disease (AD). There is promising evidence regarding the utility of CBF studies in cognition research. Age-related CBF changes could be related to a progressive neuronal loss or diminished activity and synaptic density of neurons in the brain. While a similar cause or outcome theory applies to VCI and AD, it is possible that CBF reduction might precede cognitive decline. Despite the diversity of CBF research findings, its measurement could help early detection of cognitive disorders and also understanding their underlying etiology.

Psychiatric and justice-involved populations are known to be stigmatized and particularly vulnerable to adverse outcomes during COVID-19. The increased attention toward vulnerable populations from healthcare authorities, the media, and the general public has made it critical to uncover any developing stigmatization toward these groups and the possible consequences. The prioritization of public safety and shift in the prioritization of resource allocation and service delivery could lead to a rise in negative perceptions toward these already stigmatized groups. Thus, it is imperative to consider how the unique characteristics of vulnerable groups may impact their physical and mental health as well as their care during this pandemic. In this paper, we describe the challenges that psychiatric, correctional, and forensic psychiatry populations have faced during COVID-19 and how a rise in stigmatization could lead to adverse outcomes. Specifically, we outline the influence of the media on public perceptions and how stigmatization may be reflected in the allocation of resources, policies, and related decision-making during COVID-19.
