Background: Studies in unanesthetized rats suggest that mood stabilizers approved for treating bipolar disorder downregulate brain arachidonic acid (AA) metabolism. AA plays a role in neurotransmission and neuroinflammation, among other processes. Other drugs that reduce brain AA metabolism may add to mood stabilizer action.
Methods: We reviewed randomized controlled trials (RCTs) and population studies to examine whether celecoxib, a selective cyclooxygenase (COX)-2 inhibitor, and acetylsalicylate (aspirin), a COX-1 and COX-2 inhibitor and acetylator, were useful in bipolar disorder patients on mood stabilizers. COX-1 and COX-2 metabolize AA to bioactive eicosanoids.
Results: Celecoxib significantly enhanced mood stabilizer efficacy in two 6-week RCTs involving 86 manic bipolar inpatients, and in one 8-week RCT on 49 patients with treatment-resistant bipolar depression. With regard to aspirin, a Dutch pharmacoepidemiological study involving 5145 subjects taking lithium reported symptom reduction with added chronic low dose 30-80 mg/day aspirin, while a Danish study on 321,350 subjects taking chronic 75-150 mg/day aspirin found fewer manic episodes than in subjects not on aspirin. Finally, a recent 6-week RCT using low-dose aspirin and/or minocycline showed a specific positive effect of aspirin.
Conclusions: Efficacy of both celecoxib and aspirin as adjuncts to mood stabilizers in the treatment of bipolar disorder is consistent with the AA hypothesis for mood stabilizer action in that disorder.

Introduction: Globally, one in five individuals faces unemployment, which substantially increases their risk of developing mental disorders. Understanding the relationship between unemployment and specific mental health outcomes is crucial for formulating effective policy interventions.
Methods: This study examines the relationship between unemployment and mental disorders across 201 countries from 1970 to 2020.

Psychiatric disorders pose a significant global health challenge, exacerbated by the COVID-19 pandemic and insufficiently addressed by the current treatments. This review explores the emerging role of bile acids and the TGR5 receptor in the pathophysiology of psychiatric conditions, emphasizing their signaling within the gut-brain axis. We detail the synthesis and systemic functions of bile acids, their transformation by gut microbiota, and their impact across various neuropsychiatric disorders, including major depressive disorder, general anxiety disorder, schizophrenia, autism spectrum disorder, and bipolar disorder.

People with severe mental disorders experience premature mortality compared with the general population. Several factors contribute to the mortality gap, including the adoption of unhealthy lifestyle behaviours, poor screening for physical illnesses, difficulties in accessing healthcare facilities, specific clinical features of mental disorders and some pharmacological treatment such as antipsychotic medications with serious metabolic side effects. In the present study, carried out in the framework of the LIFESTYLE trial, a funded nationwide multicentric study, we aimed to assess the impact of different antipsychotics in mediating the effectiveness of psychosocial intervention on healthy lifestyle behaviours.

Objective: This study utilized two-sample Mendelian randomization (TSMR) to investigate the bidirectional causal associations between temporomandibular disorders (TMD) and five mental disorders.
Methods: Single-nucleotide polymorphisms (SNPs) linked to TMD were extracted from the Genome-Wide Association Studies (GWAS) database. The SNPs selected as instrumental variables (IVs) were required to have strong associations with the exposure phenotype and to meet the assumptions of Mendelian randomization (MR) analysis.
