AI Article Synopsis
- The study examined the relationship between bipolar disorders and the risk of HIV infection, as well as the risk of bipolar disorders in people with HIV (PWH) and their siblings.
- It used data from a large Danish population-based study, analyzing information from over 5,000 PWH and more than 53,000 matched individuals from the general population.
- Results showed that bipolar disorder increases the risk of HIV infection significantly, especially among injection drug users, and that PWH have a notably higher risk of developing bipolar disorder, particularly in the first two years after diagnosis.
Article Abstract
Objectives: To assess whether bipolar disorders are associated with the risk of HIV infection and whether the risk of bipolar disorders is increased among people with HIV (PWH) and their siblings.
Design: Nationwide, population-based, combined matched nested case-control and cohort study of PWH of Danish origin (1995-2021), a comparison cohort from the background population, matched on date of birth and sex, and sibling cohorts.
Methods: Conditional logistic regression and Cox regression was used to calculate adjusted odds ratios (aORs) for HIV infection and hazard ratios among PWH for bipolar disorder and receipt of lithium.
Results: We included 5322 PWH and 53 220 comparison cohort members. In the case-control study, bipolar disorder was associated with an increased risk of HIV infection [aOR: 1.9, 95% confidence interval (CI): 1.2-3.0], especially when injection drug use was the route of infection (aOR: 7.6, 95% CI: 2.0-28.9). In the cohort study, we observed an increased risk of bipolar disorders among PWH, especially in the first 2 years of observation (hazard ratio: 4.2, 95% CI: 2.4-7.4), whereas the risk of receipt of lithium was lower and the CI crossed 1. The 20-year risk of bipolar disorders for PWH was approximately 1%. Siblings of PWH also had an increased risk of bipolar disorder but not to the same degree as PWH and not of receipt of lithium.
Conclusion: Bipolar disorders are associated with the risk of HIV infection, and PWH have increased risk of bipolar disorder and receipt of lithium beyond what familial factors could explain.

Functional Remediation Improves Serum BDNF and TrkB Levels in Euthymic Patients with Bipolar Disorder: A Randomized Trial Study.

Purpose: We aimed to verify the impact of functional remediation (FR) on serum brain-derived neurotrophic factor (BDNF) and tyrosine kinase receptor B (TrkB) levels, to explore the biomechanism of FR intervention in patients with euthymic bipolar disorder (BD).
Patients And Methods: This is a randomized controlled, 12-week intervention study with participants randomized into the FR group (n=39) and the treatment as usual group (TAU, n=42) at the 1∶1 ratio. 17-Hamilton Depression Rating Scale-17 (HDRS-17), Young Mania Rating Scale (YMRS), and Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) Consensus Cognitive Battery (MCCB) were used to assess affective symptoms and cognitive functioning both at baseline and week 12, respectively.
The progress in the field of clinical staging for mental disorders within the last decade: an updated systematic review.

Introduction: Clinical staging aims to refine psychiatric diagnosis by describing mental disorders on a continuum of disorder progression, with the pragmatic goal of improved treatment planning and outcome prediction. The first systematic review on this topic, published a decade ago, included 78 papers, and identified separate staging models for schizophrenia, unipolar depression, bipolar disorder, panic disorder, substance use disorder, anorexia, and bulimia nervosa. The current review updates this review by including new proposals for staging models and by systematically reviewing research based upon full or partial staging models since 2012.

Cognitive and neural mechanisms underlying bipolar disorder (BD) and its treatment are still poorly understood. Here we examined the role of adaptations in risk-taking using a reward-guided decision-making task. We recruited volunteers with high (n = 40) scores on the Mood Disorder Questionnaire, MDQ, suspected of high risk for bipolar disorder and those with low-risk scores (n = 37).

Background: Bipolar Disorder (BD) is a complex disease. It is heterogeneous, both at the phenotypic and genetic level, although the extent and impact of this heterogeneity is not fully understood. One way to assess this heterogeneity is to look for patterns in the subphenotype data.
