Circumpolar regions face unique challenges in establishing and maintaining mental health care systems, including forensic psychiatry services. The scarcity of data and lack of evidence concerning the forensic psychiatry patient (FPP) populations of Nunavut and Greenland exacerbates the challenges of informing best practices and healthcare planning. By comparing the prevalence of forensic psychiatry patients, the mental health care services, and the legislation in these two relatively similar but unique regions, insight may be gained that can help inform healthcare planning. This cross-sectional study includes all forensic psychiatry in- and outpatients in one year from Nunavut (2018) and on February 29, 2020, in Greenland. The Greenland sample (n = 93) was nearly four times larger than the Nunavut sample (n = 15) at the population level. Despite considerable differences in forensic legislation and service supply, the forensic psychiatry patients in the two areas share several similarities. A total of 87% (n = 13) in the Nunavut sample were diagnosed with a DSM-5 schizophrenia spectrum disorder or other psychotic disorder. In Greenland, 82% (n = 76) were diagnosed with an ICD-10 F2 diagnosis (schizophrenia, schizotypal and delusional disorders). Approximately 2/3 of the patients in both populations were diagnosed with substance use disorder, and 60% of the Nunavut FPP received long-acting antipsychotic injections versus 62% in Greenland. Nearly half of the FPPs in both populations had never been convicted prior to entering the forensic psychiatry system; Nunavut 45% versus Greenland 47%. A substantial proportion of Greenlandic FPPs were outpatients compared to Nunavut (83% versus 47%). This study is an essential first step toward describing a Model of Care for forensic psychiatry patients in circumpolar regions; furthermore, the clinical similarities between the two populations provide support for future joint Arctic research and the inclusion of artic forensic patients in international studies.

Although the influence of the weather on the well-being and mental health of psychiatric patients has been widely seen, the relationships between various seasonal weather factors and depressive, manic, anxiety, and psychotic states have not been systematized in the literature. The current article describes the seasonal changes in weather-related immune responses and their impact on the development of episodes of depression, mania, psychosis, and anxiety, highlighting the T-helper 1 (Th1) and Th2 immune balance as their potential trigger. In autumn-winter depression, the hyperactivation of the Th1 system, possibly by microbial/airborne pathogens, may lead to the inflammatory inhibition of prefrontal activity and the subcortical centers responsible for mood, drive, and motivation. Depressive mood periods are present in most people suffering from schizophrenia. In the spring and summertime, when the compensating anti-Th1 property of the Th2 immune system is activated, it decreases the Th1 response. In individuals immunogenetically susceptible to psychosis and mania, the inhibition of Th1 by the Th2 system may be excessive and lead to Th2-related frontal and subcortical hyperactivation and subsequent psychosis. In people suffering from bipolar disorder, hyperintense changes in white matter may be responsible for the partial activation of subcortical areas, preventing full paranoid psychosis. Thus, psychosis may be mood-congruent in affective disorders.

Review
Psychodermatology, the multidisciplinary field that explores the intricate interplay between the mind and the skin, has gained increasing recognition over the past decade. However, several knowledge gaps and unmet needs persist in the field. The objective of this narrative review was to investigate the unmet needs in the field of psychodermatology as they pertain to medical training, treatment, research, and care access. PubMed was searched from inception through December 2023 to identify articles related to psychodermatology. Findings revealed several unmet needs within the field of psychodermatology. First, there is a need for further investigation into the pathophysiology that links psychological stress to cutaneous disease including the development of novel therapies targeting key neuropeptides. Second, the existing literature focuses primarily on the pharmacologic treatment of body dysmorphic disorder and body-focused repetitive behaviors, as well as delusional parasitosis, for which the first-line agents are selective serotonin reuptake inhibitors and atypical antipsychotics, respectively. However, additional research into the efficacy and safety of the remaining psychotropic medications and the treatment of other common psychocutaneous diseases is required. Finally, there exists a significant gap in knowledge amongst clinicians tasked with treating psychocutaneous diseases. Dermatologists report low rates of training in psychodermatology and discomfort with prescribing psychotropic medications. In conclusion, increasing resources for dermatologist education on psychotropic agent use, development of new drugs targeting stress-induced skin conditions, and research on the psychocutaneous applications of current medications may greatly improve the quality and access of psychodermatology care.

BACKGROUND
Metacognition refers to appraising one's thoughts and behaviours. Deficits in metacognition are associated with psychosis-spectrum experiences, such as hallucinations and delusions, in both clinical and non-clinical populations. Assessments of metacognitive function and abilities in clinical populations often vary in administration duration, and subjectivity of scores. This study investigates associations between different measures of metacognition and their prediction of psychosis spectrum experiences using objective and self-report measures in a cross-sectional study of psychosis-spectrum disorder (PSD) participants and controls.
METHOD
Twenty-three individuals with PSD and forty-four controls were recruited online and completed in-the-moment objective ratings of metacognitive accuracy (meta-Dots Task), and retrospective self-report of metacognitive self-reflection (Beck Cognitive Insight Scale) and abilities (Metacognition Self-Assessment Scale).
RESULTS
There were group differences in self-reported metacognition, with PSD participants having lower scores of metacognitive ability, but no differences in self-reflectiveness or objective metacognitive accuracy. In the PSD group, only self-reported metacognitive ability was associated with and predicted distress about, and conviction in, delusional thoughts.
CONCLUSIONS
The findings demonstrate group differences in some self-reported, but not objective, measures of metacognition, and highlight that prediction of PSD experiences depends on the metacognitive construct being measured, and the type of measurement used.

Despite an increasing number of adults older than 60 years with psychiatric disorders, there are few studies on older patients in psychiatric emergencies and no European data. We aimed to describe the population of patients aged 60 years and older who presented to the main French psychiatric emergency centre and identify predictors of psychiatric hospitalization. This monocentric study included 300 consecutive patients aged 60 years and older. Patients presenting because of psychiatric emergencies were frequently female and lived autonomously. More than 40% had a history of at least one psychiatric hospitalization and 44% had consulted a psychiatrist in the previous 6 months. The most common reasons for consultation were depression, anxiety, sleep disorders and suicidal thoughts. Psychiatric disorders were mainly mood disorders; neurotic, stress-related and somatoform disorders; and schizophrenic, schizotypal and delusional disorders. Only 10% had a diagnosis of organic mental disorders. Overall, 39% of the patients were admitted to the psychiatric hospital. Factors predicting hospitalization were a history of psychiatric hospitalization, suicidal thoughts and a diagnosis of a mood disorder or schizophrenia/schizotypal/delusional disorder. In conclusion, among people aged 60 years and older who consulted for psychiatric emergencies, 39% had to be hospitalized in psychiatry and only psychiatric factors influenced the decision to hospitalize. Our study highlights the need for further studies of older people in psychiatric emergencies in Europe, to anticipate the needs of this specific population and adapt multidisciplinary mental health care.

We conducted a retrospective chart review to examine the gender differences in young onset Persistent Delusional Disorder (PDD) subjects (N = 236) with onset of illness before the age of 30 years. Gender differences in marital and employment status were significant (p-0.001). Delusion of infidelity and erotomania were more common in females, while males had more body dysmorphic and persecutory delusions (X-20.45, p-0.009). Males had more substance dependence (X-21.31, p < 0.001), as well as a family history of substance abuse and PDD (X-18.5, p < 0.01). To conclude, gender differences in PDD comprised some psychopathology, co-morbidity, and family history among those with young onset PDD.

Review
INTRODUCTION
One of the strangest kinds of misperceptions of the body is "Body Integrity Dysphoria" (BID), formerly named as "Body Identity Integrity Disorder" (BIID). The affected people have the feeling that a limb is not part of their body. They can feel it, they can use it, they can move it, but they cannot get along with the fact that it is a part of their own body. Most feel the need for an amputation of a leg, others of both legs, some want a palsy and use a wheelchair. Still discussed is whether other disablements such as blindness, dumbness, deafness or a desire to have an incontinency can be included in this diagnosis. This review discusses parallels and differences to transgender/trans identity, body dysmorphic disorder, alien limb syndrome, hemineglect, and self-induced amputations in schizophrenic patients. The cause for the need to be disabled is still unknown; the review gives an overview about psychological and neurological theories of explanation and what kind of therapy may help.
METHODS
This is a narrative review of about 20 years of research about Body Integrity Dysphoria by the author.
RESULTS
Overall, no psychopathological deviations were found, none of the affected persons examined by us were actually delusional or schizophrenic, which underlines that there is a neurological malfunction in the brain that has existed since birth. However, psychological mechanisms intensify the symptoms. There are clear parallels to other forms of interference between the external body and mental body representation. Different types of therapies have been able to provide help to better deal with BID, but there has been little to bring about a real cure. In contrast, BID-affected persons who achieved amputation (or other desired forms of disability) were satisfied and able to return to work.
CONCLUSIONS
BID remains an enigmatic disorder. We have learned a lot over the past 20 years that the mental and physical bodies do not have to match.

Neurobiological foundations of delusional disorder (DD) have been studied less with neuroimaging techniques when compared to other psychotic disorders. The present study aimed to delineate the neural substrates of DD by investigating neuroanatomical characteristics of the corpus callosum (CC) with statistical shape analysis (SSA) conducted on magnetic resonance images (MRI). Twenty (female:male=1:1) DSM-5 DD patients and 20 age- and gender-matched healthy individuals were included. High-resolution 3D T1 Turbo Field Echo MRI images were scanned with a 1.5 T MR device. The landmarks that were selected to determine the shape differences in CC were identified based on previous studies. Furthermore, constructed landmarks were determined and employed to better assess regional shape differences. There was no significant difference in the CC area in the mid-sagittal images between the DD patients and controls. However, DD patients exhibited a pattern of structural CC changes in various regions. The study findings emphasizes the variable subregional nature of CC in DD patients. Future SSA studies with larger samples could shed further light on DD etiology, diagnosis, classification and treatment options.

BACKGROUND
Time perspective (TP) offers a new understanding of human personality, postulating that there are individual differences in how our mind assigns our experiences to different time categories. This concept may shed new light on the role of personality traits in shaping vulnerability to the internalized stigma.
AIM
In this paper we propose a novel approach to clarifying the underpinning of self-stigma by empirically exploring its links with TP.
METHOD
We conducted a cross-sectional study among 86 patients with ICD-10 diagnoses of paranoid schizophrenia to validate the predictive role of TP for self-stigma. We used the Zimbardo Time Perspective Inventory (ZTPI), Internalized Stigma of Mental Illness scale (ISMI) and Brief Psychiatric Rating Scale (BPRS).
RESULTS
We found significant positive correlations of self-stigma with Past-Negative, Future-Negative and Present-Fatalistic TP categories and negative correlation with the Future-Positive category. The hierarchical regression analyses revealed that two TP categories and Deviation from the Balanced Time Perspective (DBTP) are significant predictors of self-stigma over and above sociodemographic and clinical control variables. Conclusion. The results of the study confirm the hypothesis that TP opens new possibilities to understand proneness or resistance to self-stigmatization, and this may provide a basis for novel approaches to anti-self-stigma interventions.
