Late-onset psychosis refers to the development of psychotic symptoms after the age of 40 and can encompass various conditions like schizophrenia, mood disorders with psychotic features, and delusional disorder. Non-pharmacological interventions are critically important in older adults with psychosis, especially considering the lack of evidence for the efficacy of antipsychotics and the high risk of side effects. Social isolation is recognized as one of the risks of late-onset psychosis, and interventions to eliminate this risk are becoming increasingly important in Japan, where social isolation among older people is widespread as society ages. We present a case of late-onset delusional disorder in which multidimensional interventions for social isolation and loneliness, which have significant impacts on symptoms, were effective in achieving persistent remission. The case involved a woman in her mid-70s who began to complain of paranoia that taking a painkiller recommended by her husband caused persistent pain. Her husband's hospitalization and the deterioration of her relationship with her children resulted in her becoming socially isolated, which intensified her delusions and led to aggressive behavior and depression. Although antipsychotic medications had a limited effect, remission was achieved through supportive psychotherapy, cognitive therapy, family education, participation in group occupational therapy, and the introduction of daycare services, which were implemented to reduce loneliness and social isolation. Specifically, supportive psychotherapy and family education for her loneliness, awareness of another possible cause of pain that she developed through Socratic questioning, and environmental adjustments played important roles in preparing her to accept cognitive therapy, achieve delusional remission, and maintain her state of remission, respectively. The interventions implemented in this case provide insights for addressing social isolation and loneliness in late-onset psychosis.

Posterior reversible encephalopathy syndrome (PRES), which was first described in 1996, is a neurologic condition characterized by a combination of clinical and neuroimaging findings. PRES may arise in the context of preeclampsia, eclampsia, renal failure, and sepsis, among other conditions. Neuropsychiatric symptoms of PRES include altered mental status, agitation, and in some cases psychosis. PRES occurring in the postpartum period is understudied, especially with regard to its psychiatric manifestations. We aim to add to the literature a case of PRES associated with psychosis and agitation in a postpartum woman, highlighting clinical implications and offering suggestions for practice. A female in her late 20s, with no significant psychiatric or medical history, presented to the hospital at 29 weeks and one day of gestation following a witnessed seizure. She was found to be hypertensive and hyponatremic, was diagnosed with eclampsia, and underwent an emergent cesarean section due to fetal malpresentation. The next day, the patient developed paranoia with acute agitation, and the psychiatry team diagnosed her with delirium with psychosis/agitation secondary to her underlying medical condition. She required intramuscular medications for agitation, was placed in restraints, and was transferred to the ICU for sedation. Subsequently, CT and MRI scans of her head both indicated that she had developed PRES. The patient's delirium and psychotic behavior resolved after appropriate treatment of her eclampsia. To our knowledge, this case report is the second documented case in the literature, of a patient who presented with PRES characterized by agitation and psychotic features in the postpartum period. Due to the significant overlap in symptoms between delirium and postpartum psychosis, this case highlights the crucial importance of interdisciplinary collaboration for accurate diagnosis and prompt treatment of PRES in the postpartum period. The case also speaks to the importance of differentiating postpartum psychosis associated with a primary psychiatric disorder from delirium arising in postpartum patients with or without a previous psychiatric history.

INTRODUCTION
Predictive models of psychotic symptoms could improve ecological momentary interventions by dynamically providing help when it is needed. Wearable sensors measuring autonomic arousal constitute a feasible base for predictive models since they passively collect physiological data linked to the onset of psychotic experiences. To explore this potential, we investigated whether changes in autonomic arousal predict the onset of hallucination spectrum experiences (HSE) and paranoia in individuals with an increased likelihood of experiencing psychotic symptoms.
METHOD
For 24 h of ambulatory assessment, 62 participants wore electrodermal activity and heart rate sensors and were provided with an Android smartphone to answer questions about their HSE-, and paranoia-levels every 20 min. We calculated random forests to detect the onset of HSEs and paranoia. The generalizability of our models was tested using leave-one-assessment-out and leave-one-person-out cross-validation.
RESULTS
Leave-one-assessment-out models that relied on physiological data and participant ID yielded balanced accuracy scores of 80 % for HSE and 66 % for paranoia. Adding baseline information about lifetime experiences of psychotic symptoms increased balanced accuracy to 82 % (HSE) and 70 % (paranoia). Leave-one-person-out models yielded lower balanced accuracy scores (51 % to 58 %).
DISCUSSION
Using passively collectible variables to predict the onset of psychotic experiences is possible and prediction models improve with additional information about lifetime experiences of psychotic symptoms. Generalizing to new individuals showed poor performance, so including personal data from a recipient may be necessary for symptom prediction. Completely individualized prediction models built solely with the data of the person to be predicted might increase accuracy further.

BACKGROUND
The Coronavirus 2019 disease (COVID-19) caused drastic changes in people's lifestyle that affected TMD characteristics through its physical and psychological influences. The aim of this study was to define the clinical and psychological characteristics of a large group of well-defined TMD patients and seek their differences between before and during the COVID-19 pandemic to establish points of care to be emphasized in the post-pandemic era.
METHODS
TMD patients diagnosed by the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) aged ≥ 18 were analyzed. Samples between September, 2017 to July, 2019 (n = 455) and March, 2021 to June, 2022 (n = 338) were collected to represent before and during COVID-19, respectively. The Graded Chronic Pain Scale (GCPS) and Symptom Checklist-90-Revision (SCL-90-R) were used to evaluate disability levels and psychological status. Clinical indices were compared between COVID periods and factors related to higher pain levels were investigated according to pandemic period.
RESULTS
More patients reported pain on palpation of the masticatory muscles during the pandemic (p = 0.021) while the number decreased for neck muscles (p = 0.001) and TMJ (p < 0.001) areas. Patients reporting nocturnal bruxism (23.3-29.6%) and clenching (45.1-54.7%) significantly increased during the pandemic. TMD patients with pain without disability were more common during the pandemic regardless of pain intensity (p < 0.001). The number of patients expressing interference in daily activities decreased drastically during COVID-19 regardless of disability level (p < 0.001). Factors associated with higher than moderate pain intensity (CPI ≥ 50) were insomnia (odds ratio [OR] = 1.603, p = 0.047) and somatization (OR = 1.082, p < 0.001) before the pandemic. During the pandemic, age (OR = 1.024, p = 0.007), somatization (OR = 1.070, p = 0.006), and paranoid ideation (OR = 1.117, p = 0.003) were significantly associated with higher pain intensity.
CONCLUSIONS
The results of our study underline the importance of evaluating psychological profiles of TMD patients, especially somatization, paranoid ideation and psychoticism, in exceptional situations that may cause a change in individual mental status. This will lead to a better understanding of the individual TMD patient and help in planning personalized treatment strategies that will assist the patient in adjusting to changes occurring in special environments such as the COVID-19 pandemic.

Meta-Analysis
IMPORTANCE
Psilocybin has been studied in the treatment of depression and anxiety disorders. Clinical studies have mainly focused on efficacy, with systematic reviews showing favorable efficacy; however, none have primarily focused on psilocybin safety.
OBJECTIVE
To evaluate the acute adverse effects of psilocybin at therapeutic doses in the treatment of depression and anxiety.
DATA SOURCES
MEDLINE via PubMed, Web of Science, and ClinicalTrials.gov were searched for publications available between 1966 and November 30, 2023.
STUDY SELECTION
Randomized, double-blind clinical trials that reported adverse effects of psilocybin in patients treated for depression and anxiety were screened.
DATA EXTRACTION AND SYNTHESIS
Data were independently extracted by 2 authors and verified by 2 additional authors following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline. The inverse variance method with the Hartung-Knapp adjustment for the random-effects model was used, with a continuity correction of 0.5 for studies with 0 cell frequencies. Sensitivity analysis was conducted by sequentially removing 1 study at a time to assess the robustness of the results.
MAIN OUTCOMES AND MEASURES
The primary outcome was considered as the adverse effects of psilocybin at high and moderate (ie, therapeutic) dose regimens and compared with placebo, low-dose psilocybin, or other comparator in the treatment of depression and/or anxiety.
RESULTS
Six studies met the inclusion criteria with a total sample of 528 participants (approximately 51% female; median age 39.8 years; IQR, 39.8-41.2). Seven adverse effects were reported in multiple studies and included in the analysis. Among these, headache (relative risk [RR], 1.99; 95% CI 1.06-3.74), nausea (RR, 8.85; 95% CI, 5.68-13.79), anxiety (RR, 2.27; 95% CI, 1.11-4.64), dizziness (RR, 5.81; 95% CI, 1.02-33.03), and elevated blood pressure (RR, 2.29; 95% CI, 1.15- 4.53) were statistically significant. Psilocybin use was not associated with risk of paranoia and transient thought disorder.
CONCLUSIONS AND RELEVANCE
In this meta-analysis, the acute adverse effect profile of therapeutic single-dose psilocybin appeared to be tolerable and resolved within 48 hours. However, future studies need to more actively evaluate the appropriate management of adverse effects.

The specialized field of forensic psychiatry deals with the care of criminal offenders who suffer from severe mental disorders. As this field is positioned at the intersection of illness, crime, and security, it poses complex challenges. While high-quality clinical studies in forensic psychiatry settings are limited, recent investigations have suggested yoga as a complementary clinical tool within correctional environments. This report of a quasi-experimental study examines the impact of a 10-week trauma-adapted yoga intervention on mental health, antisocial and aggressive behaviors, pain perception, cravings, and character maturity among 56 patients in various forensic psychiatry clinics across Sweden. In the current study, the yoga group demonstrated noteworthy reductions in negative affect states, anxiety, phobic anxiety, paranoid ideations, interpersonal sensitivity, hostility, and overall psychological distress. These reductions were not observed in the comparison group. Additionally, the yoga group exhibited a significant decrease in pain frequency and strengthened self-directedness. However, there were no significant changes in aggressive, antisocial, or self-harm behaviors or cravings in either group. The between-group analyses did not yield significant results, except for pain intensity. The trauma-adapted yoga intervention implemented within forensic psychiatry settings shows feasibility and results in multiple positive changes in patients' health.

Kratom is a plant extract readily available for purchase in the USA. It is known to produce both stimulant and opioid-related effects, predisposing it to abuse. The long-term effects of kratom are poorly understood. In rare cases, serious side effects have been reported. Here, we report a case of a patient with a history of bipolar type schizoaffective disorder presenting with acute onset paranoia and delusions. The patient had been hospitalized seven times previously with psychotic symptoms, with no reported history of paranoid delusional thought content in previous admissions. It was discovered that the patient had been ingesting increasingly large quantities of kratom in the weeks leading up to the admission. It is believed that kratom may be responsible for the novel symptoms contributing to the patient's acute psychiatric decompensation.

Stalking perpetrators may suffer from maladaptive personality traits, particularly if they stalk in the context of an (ex-)intimate relationship. To date, no study has examined how different personality attributions may relate to stalker motivation, or the behaviors they engage in, and how this differs across victim-perpetrator relationships. Further, the perspective of the victim is often not taken into consideration, even though most stalking victims know their stalker intimately and a majority are stalked by a former or current partner. The present study employed a correlational design to assess the relationship between stalking behaviors, motivation to stalk, and personality attributions, as perceived by the victim across an ex-intimate or other victim-perpetrator relationship. The study sample consisted of 100 victims of stalking (63% ex-intimate; 85% female) who were recruited through a National Stalking Helpline. Results align with and extend the results of previous researchers, most notably the high proportion of reported Cluster B-aligned personality attributions among stalkers, as well as the proportion of more under-researched personality attributions, and their associated risks. Victims of an ex-intimate partner were more likely to report their stalker was motivated by intimacy, and personality attributions aligned with both borderline and paranoid PD were more often reported than in other relationship contexts. Results and clinical implications are discussed.

Predictive processing accounts of psychosis conceptualize delusions as overly strong learned expectations (prior beliefs) that shape cognition and perception. Paranoia, the most prevalent form of delusions, involves threat prior beliefs that are inherently social. Here, we investigated whether paranoia is related to overly strong threat prior beliefs in face perception. Participants with subclinical levels of high (n = 109) versus low (n = 111) paranoia viewed face stimuli paired with written descriptions of threatening versus trustworthy behaviors, thereby activating their threat versus trustworthiness prior beliefs. Subsequently, they completed an established social-psychological reverse correlation image classification (RCIC) paradigm. This paradigm used participants' responses to randomly varying face stimuli to generate individual classification images (ICIs) that intend to visualize either facial prior belief (threat vs. trust). An independent sample (n = 76) rated these ICIs as more threatening in the threat compared to the trust condition, validating the causal effect of prior beliefs on face perception. Contrary to expectations derived from predictive processing accounts, there was no evidence for a main effect of paranoia. This finding suggests that paranoia was not related to stronger threat prior beliefs that directly affected face perception, challenging the assumption that paranoid beliefs operate on a perceptual level.
