Religious Activity, Psychotic Features, and Suicidality in 688 Acute Psychiatric Inpatients.

BACKGROUND: Religiosity has been linked to mental health outcomes for decades. This study examined the potential relationship between religiosity and demographic and clinical variables in a sample of psychiatric inpatients. METHODS: In total, 688 adults admitted to an acute psychiatric facility with a primary mood or psychotic disorder completed the Duke University Religion Index (DUREL). The DUREL measures religious activity in 3 domains: organizational religious activity (ORA), nonorganizational religious activity (NORA), and intrinsic (or subjective) religiosity (IR). We categorized scores into high and low religiosity. Bivariate analyses with χ and independent sample t tests were used to examine the association between the DUREL subscales and demographic, clinical, and outcome measures. A generalized linear model was used to identify predictors of suicidality, psychosis, and 30-day rehospitalization. RESULTS: Elevated religious activity was common in the inpatient sample, with 58% categorized as high IR, 43% as high NORA, and 36% as high ORA. For all 3 DUREL subscales, high religiosity scores were associated with significantly more psychosis (P<0.05) and significantly less suicidal ideation (P<0.001). High ORA (P=0.001) and high IR (P=0.01) were associated with significantly fewer suicide attempts. High ORA scores were also associated with an increased length of stay (P<0.05) and more frequent 30-day readmission rates (P=0.01). In the generalized linear model, predictors of lower levels of suicidality were high ORA, high IR, and a diagnosis of schizophrenia, schizoaffective disorder, or other psychotic disorder, whereas a diagnosis of depressive disorder was associated with greater suicidality. Predictors of psychosis were high IR and Hispanic ethnicity, whereas a diagnosis of depressive disorder was associated with lower rates of psychosis. Female inpatients were more likely than male inpatients to score high on the ORA (P<0.05), NORA (P<0.05), and IR (P<0.0001) subscales. In addition, a significant relationship was detected between age and high IR scores (P<0.005), with increasing age associated with higher IR scores. CONCLUSIONS: Although preliminary, these results suggest that a brief measure of religiosity may provide important information concerning clinical features and acute outcomes in patients hospitalized with serious mental illness.

A Contagious Disorder: Folie à Deux and Dementia.

BACKGROUND: Folie à deux is a clinical condition that was first described in 19th century. It is a psychotic disorder in which two closely associated individuals share a similar delusional system. OBJECTIVES: The aim of this article is to review the nosological significance of folie à deux and to explore the disorder among patients with dementia. METHODS: Medline and Google Scholar searches were conducted for relevant articles, chapters, and books published before 2017. Search terms used included dementia, folie à deux, induced delusional disorder, neurocognitive disorders, shared psychotic disorder. Publications found through this indexed search were reviewed for further relevant references. RESULTS AND CONCLUSION: Cases of Folie à deux involving patients with dementia are reported quite infrequently. Most of the studies on the topic consist in case reports. Clinicians are obliged to treat the disorder. They should be alert to the potential high risk inherent this psychotic syndrome.

An Unusual Case of Acute Psychosis With Obsessive-Compulsive Features Following Arsenic Poisoning.

Arsenic exposure, particularly the chronic type, can lead to poisoning with manifestations presenting in multiple organ systems. However, acute psychosis is not a commonly described manifestation of arsenic exposure. In this report, we present the case of a patient who developed acute psychosis with hallucinations, disorganized thinking, and obsessive-compulsive symptoms following chronic occupational arsenic exposure. The patient was treated with the combination of an antipsychotic and an antidepressant and he responded well with significant improvement in both the acute psychosis and obsessive-compulsive symptoms. The authors concluded that patients can develop atypical symptoms, including acute psychosis, following arsenic poisoning. In the case described in this report, the patient also presented with a new onset of obsessive-compulsive symptoms. Given this rare manifestation of arsenic poisoning for which there is no clearly defined treatment regimen, this case suggests that the use of a combination of an antipsychotic and an antidepressant may be considered in the rare event of psychosis with obsessive-compulsive features following arsenic poisoning.

Gut-brain peptides in corticostriatal-limbic circuitry and alcohol use disorders.

Peptides synthesized in endocrine cells in the gastrointestinal tract and neurons are traditionally considered regulators of metabolism, energy intake, and appetite. However, recent work has demonstrated that many of these peptides act on corticostriatal-limbic circuitry and, in turn, regulate addictive behaviors. Given that alcohol is a source of energy and an addictive substance, it is not surprising that increasing evidence supports a role for gut-brain peptides specifically in alcohol use disorders (AUD). In this review, we discuss the effects of several gut-brain peptides on alcohol-related behaviors and the potential mechanisms by which these gut-brain peptides may interfere with alcohol-induced changes in corticostriatal-limbic circuitry. This review provides a summary of current knowledge on gut-brain peptides focusing on five peptides: neurotensin, glucagon-like peptide 1, ghrelin, substance P, and neuropeptide Y. Our review will be helpful to develop novel therapeutic targets for AUD.

Lateral hypothalamic kindling induces manic-like behavior in rats: a novel animal model.

The lateral hypothalamus integrates critical physiological functions such as the sleep-wake cycle, energy expenditure, and sexual behaviors. These functions are severely dysregulated during mania. In this study, we successfully induced manic-like behavioral phenotypes in adult, male Wistar rats through bilateral lateral hypothalamic area kindling (LHK). To test the validity of the model, we studied the effect of standard antimanic medications lithium (47.5 mg/kg) or valproic acid (200 mg/kg) twice/day for 15 days in attenuating manic-like behaviors in the LHK rat. Compared with pre-kindling behaviors, LHK rats displayed significantly increased sexual self-stimulation (P = 0.034), excessive rearing (P = 0.0005), feeding (P = 0.013), and grooming (P = 0.007) during the kindling interval. LHK rats also drank more alcohol during the mania-induction days compared with baseline ethanol consumption levels (P = 0.01). Moreover, LHK rat exhibited increased total locomotor activity (P = 0.02) with reduced rest interval (P < 0.001) during the mania induction and post-mania days compared with baseline activity levels and rest intervals. Chronic administration of lithium or valproic acid significantly attenuated manic-like behaviors in the LHK rat model. Given the behavioral phenotype and the response to standard antimanic medications, the LHK rats may provide a model for studying manic psychopathology in humans.
