Schizophrenia lacks a clear definition at the neuroanatomical level, capturing the sites of origin and progress of this disorder. Using a network-theory approach called epicenter mapping on cross-sectional magnetic resonance imaging from 1124 individuals with schizophrenia, we identified the most likely "source of origin" of the structural pathology. Our results suggest that the Broca's area and adjacent frontoinsular cortex may be the epicenters of neuroanatomical pathophysiology in schizophrenia. These epicenters can predict an individual's response to treatment for psychosis. In addition, cross-diagnostic similarities based on epicenter mapping over of 4000 individuals diagnosed with neurological, neurodevelopmental, or psychiatric disorders appear to be limited. When present, these similarities are restricted to bipolar disorder, major depressive disorder, and obsessive-compulsive disorder. We provide a comprehensive framework linking schizophrenia-specific epicenters to multiple levels of neurobiology, including cognitive processes, neurotransmitter receptors and transporters, and human brain gene expression. Epicenter mapping may be a reliable tool for identifying the potential onset sites of neural pathophysiology in schizophrenia.

BACKGROUND
The neurobiological basis of delusional disorder is less explored through neuroimaging techniques than in other psychotic disorders. This study aims to provide information about the neural origins of delusional disorder (DD) by examining the neuroanatomical features of some basal nuclei with magnetic resonance imaging (MRI) texture analysis.
MATERIALS AND METHODS
Twenty DD patients and 20 healthy individuals were included in the study. Globus pallidus, putamen, and caudate nuclei were selected individually with a region of interest (ROI) on the axial MRI images. The entire texture analysis algorithm applied to all selected ROIs was done with an in-house software. Nuclei on both sides were taken as separate samples.
RESULTS
There were no significant differences between groups in terms of age and gender. The average "mean, median and maximum" values of all three nuclei were decreased in DD patients. The small putamen area and the differences detected in different tissue parameters for all three nuclei in delusional disorder patients indicate that they differ in delusional disorder from normal controls (p < 0.05).
CONCLUSION
The differences detected in the texture parameters for all three nuclei indicate that there is something different in the DD from in the normal controls. Neuroimaging studies with larger samples and different techniques in the future may shed light on the etiology of delusional disorder.

Catatonia is a complex neuropsychiatric syndrome involving a constellation of psychomotor disturbances including catalepsy, waxy flexibility, stupor, mutism, negativism, agitation, posturing, stereotypes, mannerisms, grimacing, echolalia, and echopraxia. Catatonia occurs in several conditions including psychotic, affective and neurodevelopmental disorders such as autism spectrum disorder (ASD). ASD is a neurodevelopmental disorder characterized by persistent deficits in communication, social interaction, restricted interests, repetitive behaviours and sensory sensitivities. Catatonia can occur in response to life stressors such as extreme fear or threat, interpersonal conflict, tragic events or following significant loss. Those with ASD may be particularly vulnerable to the negative impact of stressors and the link between catatonia and ASD is being increasingly recognized. The overlapping features of catatonia and ASD make it difficult to differentiate often resulting in delayed or missed diagnosis. Catatonia in ASD remains a significant clinical challenge; it is difficult to diagnose and can pose debilitating difficulties for those affected. Catatonia is a treatable condition and prompt recognition is vital in securing the best possible outcome. We report a complex and unique case of a 15-year-old boy who presented with severe cognitive and functional decline with a background history of significant bullying and deterioration in his mental state. This case posed a diagnostic conundrum leading to a diagnosis of underlying ASD, anxiety and trauma.

Review
BACKGROUND
There is some evidence of an association between inflammation in the pathogenesis of mental disorders. Soluble urokinase plasminogen activator receptor (suPAR) is a biomarker of chronic inflammation, which provides a more stable index of systemic inflammation than more widely used biomarkers. This review aims to synthesise studies that measured suPAR concentrations in individuals with a psychiatric disorder, to determine if these concentrations are altered in comparison to healthy participants.
METHOD
Comprehensive literature searches from inception to October 2023 were conducted of five relevant databases (PubMed, Web of Science, Embase, Scopus, APA PsychInfo). Random-effects meta-analyses were performed to compare the standardised mean difference of blood suPAR levels (i.e. plasma or serum) for individuals with any psychiatric disorder relative to controls. Separate meta-analyses of suPAR levels were conducted for individuals with schizophrenia or other psychotic disorder and depressive disorder. Risk of bias was assessed using the Newcastle Ottawa Scale. Post-hoc sensitivity analyses included excluding studies at high risk of bias, and analyses of studies that measured suPAR concentrations either in serum or in plasma separately.
RESULTS
The literature search identified 149 records. Ten full-text studies were screened for eligibility and 9 studies were included for review. Primary analyses revealed no significant difference in suPAR levels between individuals with any psychiatric disorder compared to controls (k = 7, SMD = 0.42, 95 % CI [-0.20, 1.04]). However, those with depressive disorder had elevated suPAR levels relative to controls (k = 3, SMD = 0.61, 95 % CI [0.34, 0.87]). Similarly, secondary analyses showed no evidence of a significant difference in suPAR levels in individuals with any psychiatric disorder when studies at high risk of bias were excluded (k = 6, SMD = 0.54, 95 % CI [-0.14, 1.22]), but elevated suPAR concentrations for those with schizophrenia or other psychotic disorder were found (k = 3, SMD = 0.98, 95 % CI [0.39, 1.58]). Furthermore, studies that analysed plasma suPAR concentrations found elevated plasma suPAR levels in individuals with any psychiatric disorder relative to controls (k = 5, SMD = 0.84, 95 % CI [0.38, 1.29]), while studies measuring serum suPAR levels in any psychiatric disorder did not find a difference (k = 2, SMD = -0.61, 95 % CI [-1.27, 0.04]). For plasma, elevated suPAR concentrations were also identified for those with schizophrenia or other psychotic disorder (k = 3, SMD = 0.98, 95 % CI [0.39, 1.58]).
DISCUSSION
When studies measuring either only serum or only plasma suPAR were considered, no significant difference in suPAR levels were observed between psychiatric disorder groups, although significantly elevated suPAR levels were detected in those with moderate to severe depressive disorder. However, plasma suPAR levels were significantly elevated in those with any psychiatric disorder relative to controls, while no difference in serum samples was found. A similar finding was reported for schizophrenia or other psychotic disorder. The plasma findings suggest that chronic inflammatory dysregulation may contribute to the pathology of schizophrenia and depressive disorder. Future longitudinal studies are required to fully elucidate the role of this marker in the psychopathology of these disorders.

Narrative exposure therapy (NET) is a recommended intervention for people with multiple trauma histories; however, research is lacking into its use with people experiencing psychosis, many of whom report multiple trauma histories. This study aimed to explore experiences of NET in early intervention in psychosis (EIP) services. Eight clinicians and four experts with lived experience (experts by experience) of psychosis and multiple trauma were interviewed on a single occasion using two versions (clinician and expert by experience) of a semi-structured interview schedule. Data was analysed using thematic analysis. Five overarching themes were generated, relating to fear and avoidance of memories, importance of trust, organizing memories and making new meaning, reconnecting with emotions, and considerations when delivering NET in EIP. Directly addressing the impact of multiple trauma in people experiencing first episode psychosis is frightening and emotive, but helps to address painful memories and organize them into a personal narrative. Increases in distress and anomalous experiences were carefully considered by clinicians, but typically outweighed by the benefits of NET. Challenges were comparable to those described in non-psychosis research. Implications for clinical practice and future research are outlined.

Implementation of guidelines on Family Involvement for persons with Psychotic disorders: a pragmatic cluster randomized trial. Effect on relatives' outcomes and family interventions received.
BACKGROUND
Family interventions (FI) are recommended as part of the treatment for psychotic disorders, but the implementation in mental health services is generally poor. Recently, The Implementation of guidelines on Family Involvement for persons with Psychotic disorders (IFIP) trial, demonstrated significant improvements in implementation outcomes at cluster-level. This sub-study aims to examine the effectiveness of the IFIP intervention on relatives' outcomes and received FI.
METHODS
A cluster randomized controlled trial, was conducted in 15 Norwegian Community Mental Health Center (CMHC) units that were randomized to either the IFIP intervention, including implementation interventions and clinical interventions, or treatment as usual (TAU). The clinical interventions consisted of FI: basic family involvement and support (BFIS) to all patients and family psychoeducation (FPE) to as many as possible. Patients with psychotic disorders and their closest relative were invited to fill in questionnaires at inclusion and 6 months and 12 months follow-up. Received FI was reported by both relatives and clinicians. The relatives' primary outcome was satisfaction with health service support, measured by the Carer well-being and support questionnaire part B (CWS-B). The relatives' secondary outcomes were caregiver experiences, expressed emotions and quality of life. Patients' outcomes will be reported elsewhere.
RESULTS
In total 231 patient/relative pairs from the CMHC units were included (135 intervention; 96 control).The relatives in the intervention arm received an increased level of BFIS (p=.007) and FPE (p < 0.05) compared to the relatives in the control arm, including involvement in crisis planning. The primary outcome for relatives' satisfaction with health service support, showed a non-significant improvement (Cohen's d = 0.22, p = 0.08). Relatives experienced a significant reduced level of patient dependency (Cohen's d = -0.23, p = 0.03).
CONCLUSION
The increased support from clinicians throughout FI reduced the relatives' perceived level of patient dependency, and may have relieved the experience of responsibility and caregiver burden. The COVID-19 pandemic and the complex and pioneering study design have weakened the effectiveness of the IFIP intervention, underscoring possible potentials for further improvement in relatives' outcomes.

Antipsychotics are the mainstay treatment for the majority of severe mental illnesses. Such patients are also more prone to develop medical comorbidities, which complicate the treatment decisions. It is estimated that up to 40% of individuals with schizophrenia have impaired glucose tolerance (IGT) or diabetes, which can be attributed to a combination of genetic, lifestyle, and medication-related factors. Some widely used antipsychotic medications like olanzapine, risperidone, and clozapine have been associated with an increased risk of weight gain, insulin resistance, and other metabolic abnormalities, which can worsen IGT and increase the risk of developing diabetes. Among second-generation antipsychotics (SGAs), amisulpride, aripirazole, and ziprasidone have a fairly low potency to cause obesity and hyperglycemia. In this context, clinicians must balance the benefits and risks of different antipsychotic medications and consider the individual's specific needs and preferences. Here, we shall discuss three cases, to ascertain how the use of amisulpride helped in glycemic control, and also reflect on probable etiologies leading to deranged glucose levels.

Gender confusion in the context of mania is very less frequently described in the literature. The actuality of a primary psychiatric condition in gender identity complaint has significant bearing on the applicable operation and prognostic. This case series describes cases of bipolar affective complaint presenting in a manic occasion whose mania was marked by hypersexuality and the desire to be of opposite gender. Both of these symptoms resolved with treatment of the manic occasion. Case 1 describes a 17-year-old male presenting with an episodic illness, with current manic episode. He is currently interested in boys and has started enjoying feminine activities. Upon treatment, his symptoms showed improvement. Case 2 describes a 22-year-old gay male, with a total duration of 7 years, current episode mania. Now, he is considering himself a lesbian and feels he is mentally a modern female. After 4 months of treatment, there was significant improvement in his complaints and he stopped cross-dressing as a female. Case 3 shows a 21-year-old female, with manic episode. After 1 month, the patient began acting and speaking more like a boy. The patient has shown improvement while taking lithium 900 mg, divalproex sodium 1000 mg, risperidone 6 mg, and chlorpromazine 150 mg. Gender dysphoria occurring along with a psychotic episode and resolving with management of the primary psychiatric disorder are rarely recorded. The central issue in similar cases is a proper workup and diagnosis. Psychiatrists should be aware of this scenario so that proper treatment strategies for gender incongruence can be planned and not be brushed aside as "just another symptom."

Prevalence of childhood trauma in patients with psychiatric disorders and its association with perceived social support and suicide attempts: A cross-sectional observational study in a tertiary hospital in South India.
BACKGROUND
Adverse childhood experiences include exposure of children to physical abuse, physical neglect, emotional neglect, emotional abuse, and sexual abuse. Children exposed to severe maltreatment and trauma during their early childhood are at a higher risk of early onset of psychiatric disorders.
AIM
To find the prevalence of childhood adverse experiences in psychiatric patients and its association with perceived social support and suicidal attempts.
MATERIALS AND METHODS
A cross-sectional observational study was conducted in the psychiatry outpatient department at a tertiary care hospital in Kerala. Patients with a diagnosis of substance use disorders, psychotic disorders, mood disorders, and neurotic disorders according to ICD-10 (F10-F45) and in remission were included in the study. Institutional Ethical Committee approval and informed consent from the participants were obtained. Socio-demographic and clinical details were obtained. Childhood Trauma Questionnaire-Short Form and Multidimensional scale of Perceived Social Support were administered. Descriptive statistics and Chi-square test were employed for data analysis.
RESULTS
Eighty-five per cent of the subjects had a history of at least one type of childhood trauma. Emotional abuse was the most commonly reported type of trauma. Among patients with childhood trauma, 47.2% reported high levels of perceived social support, whereas 18.5% individuals reported a history of at least one suicide attempt.
CONCLUSIONS
A significant proportion of patients with psychiatric disorders in an Indian setting have experienced childhood trauma. Childhood trauma in psychiatric disorders is associated with a higher risk of attempting suicide.

Eidetic images are a relatively rare phenomenon in the practice of a psychiatrist. They are described in the category of perception disorders as images or memories which, thanks to their plasticity, vividness and detail, are very similar to the currently experienced sensory perceptions. However, it should be remembered that their occurrence is not associated with any mental disorders, and they are also observed in some healthy people. This paper presents a case report of a patient with complaints about "voiced," plastic images - the course of his psychiatric hospitalization and the psychological diagnostics carried out at that time. The authors point out the difficulties in differentiating, first of all, with auditory pseudo-hallucinations and make an attempt at psychopathological classification of the patient's symptoms. The discussion on possible disease mechanisms of this phenomenon is based on reports as well as research on the phenomenon of imagination and eidetic perceptions, and the aim of this study is to draw the attention of diagnosticians to the category of psychological phenomena with an eidetic character, which may allow them to avoid incorrect recognition of them as an element of psychotic disorders of perception.
