Review
The perinatal period is an extremely delicate phase that can involve a high risk for onset of depressive disorders. The Edinburgh Postnatal Depression Scale (EPDS) is a widely validated instrument for assessing perinatal depressive symptoms, including the dimension of anhedonia. There are studies suggesting that the neural mechanism underlying the occurrence of anhedonia in patients with major depressive disorder (MDD) and bipolar depression (BD) might be distinct. Anhedonia seems to represent a more stable and frequent symptom in women with postpartum bipolar relative to unipolar depressive disorder and is associated with significantly higher depressive symptom severity. Perinatal medicine is an important component of women's health. Treatment of anhedonia can be challenging, and the most effective treatment can be a combination of psychotherapy and medication, but the screening of anhedonia in peripartum women can prevent the development of other psychiatric disorders and maladaptive behaviors.

Review
INTRODUCTION
The data suggests that in children and adolescents, bipolar disorder (BD) and attention deficit hyperactivity disorder (ADHD) may be strongly correlated. Even though drugs for ADHD and BD are largely accepted, there is relatively little research on the management of comorbidity in children and adolescents, particularly in terms of safety. We provide a synthesis of these findings because one hasn't been made yet.
AREAS COVERED
As a primary outcome, we wanted to determine whether stimulant or non-stimulant treatment of children and adolescents with ADHD and comorbid BD was effective. As a secondary outcome, we wanted to determine tolerability, especially the risk of mood switch.
EXPERT OPINION
The findings of this systematic review suggest that methylphenidate, when used with a mood stabilizer, may be safe and not significantly increase the risk of a manic switch or psychotic symptoms when used to treat ADHD that co-occurs with a BD. In situations where stimulants are ineffective or have low tolerance, atomoxetine also seems to be a good alternative, and also in cases of co-morbid anxiety, oppositional defiant disorder, conduct disorders, ICT disorders, and substance use disorders. Additional research with a higher level of evidence is necessary to corroborate these preliminary findings.

OBJECTIVES
This study aimed to assess the capabilities of ChatGPT (Chat Generative Pre-Trained Transformer) in generating informative content related to bipolar disorders. The objectives were to evaluate its ability to provide accurate information on symptoms, classification, causes, and management of bipolar disorder and to explore its creativity in generating topic-related songs.
METHODS
ChatGPT3 was used for the study, and a series of clinically relevant questions were asked to test its knowledge and creativity. Questions ranged from common symptom descriptions to more artistic requests for songs related to bipolar disorder.
RESULTS
ChatGPT demonstrated the capacity to provide basic and informative material on bipolar disorders, including descriptions of symptoms, classification types, causes, and treatment options. It also showed creativity in generating songs that capture the nuances of bipolar symptoms, both during high and low states.
CONCLUSIONS
While ChatGPT3 can offer superficial information on psychiatric topics like bipolar disorder, its inability to provide accurate and up-to-date references limits its utility for creating a comprehensive review article for scientific journals. However, it may be helpful in generating educational material and assisting in component tasks for those with bipolar disorder or other psychiatric conditions. As newer versions of AI models are continually developed, their capabilities in producing more accurate and advanced content will need further evaluation.

Patients may present with manic symptoms in medical settings such as emergency rooms and on inpatient medical floors, leading to psychiatric consultation to try to determine the etiology of the symptoms. It is crucial to clarify whether the mania is secondary to a medical illness or whether the patient's symptoms are from a primary bipolar disorder. In this issue, we publish 2 case reports of patients presenting with manic symptoms in medical settings. The first case involves polymicrogyria in the frontal lobe of the brain as a cause of secondary mania. The second case involves a patient who was previously diagnosed with bipolar disorder and subsequently developed symptoms of Behçet's disease. In this case, it appears likely that the bipolar disorder was primary, and that the Behçet disease and the bipolar disorder may have exacerbated each other. Given the complexities involved in assessing and treating patients, especially in acute or emergency settings, it is important for primary medical and psychiatric providers to collaborate and communicate well in assuring that they obtain a thorough history of their patients' symptoms and that patients receive a comprehensive medical evaluation before psychiatric treatment is started.

Review
BACKGROUND
A growing body of evidence suggests that pediatric bipolar disorder (PBD) frequently co-occurs with comorbid psychiatric disorders that may impact functioning.
OBJECTIVE
To review existing literature on the prevalence of psychiatric comorbidity and general functioning in patients with a primary diagnosis of PBD.
METHODS
We performed a systematic literature search on the PubMed, Embase and PsycInfo databases on November 16th, 2022. We included original papers on patients ≤18 years with primary PBD and any comorbid psychiatric disorder, diagnosed according to a validated diagnostic tool. Risk of bias of the individual studies was assessed using the STROBE checklist. We calculated weighted means to assess the comorbidity prevalence. The review complied with PRISMA statement guidelines.
RESULTS
Twenty studies with a total study population of 2722 patients with PBD were included (mean age = 12.2 years). We found an overall high prevalence of comorbidity in patients with PBD. The most common comorbidities were attention-deficit-hyperactivity disorder (ADHD) (60%) and oppositional defiant disorder (ODD) (47%). Anxiety disorders, obsessive-compulsive disorder, conduct disorder, tic disorders and substance-related disorders affected between 13.2% and 29% of patients, while one in 10 had comorbid mental retardation or autism spectrum disorder (ASD). The prevalence of comorbid disorders was lower in studies that assessed the current prevalence in patients in full or partial remission. General functioning was overall not specifically decreased in patients with comorbidity.
CONCLUSIONS
Comorbidity across a broad range of disorders was high in children diagnosed with PBD, especially regarding ADHD, ASD, behavioral and anxiety disorders including OCD. Future original studies should assess current prevalence of comorbidities in patients with PBD who are in remission to obtain more reliable estimates of psychiatric comorbidity in this patient group. The review highlights the clinical and scientific importance of comorbidity in PBD.

Review
Rapid-cycling in bipolar disorder (RC-BD) is associated with greater illness morbidity and inferior treatment response but many aspects remain unclear, prompting this systematic review of its definitions, prevalence, and clinical characteristics. We searched multiple literature databases through April 2022 for systematic reviews or meta-analyses on RC-BD and extracted associated definitions, prevalence, risk-factors, and clinical outcomes. We assessed study quality (NIH Quality Assessment Tool) and levels of evidence (Oxford criteria). Of 146 identified reviews, 22 fulfilling selection criteria were included, yielding 30 studies involving 13,698 BD patients, of whom 3777 (27.6% [CI: 26.8-28.3]) were considered RC-BD, as defined in 14 reports by ≥4 recurrences/year within the past 12 months or in any year, without considering responsiveness to treatment. Random-effects meta-analytically pooled one-year prevalence was 22.3% [CI: 14.4-32.9] in 12 reports and lifetime prevalence was 35.5% [27.6-44.3] in 18 heterogenous reports. Meta-regression indicated greater lifetime prevalence of RC-BD among women than men (p=0.003). Association of RC-BD with suicide attempts, and unsatisfactory response to mood-stabilizers was supported by strong evidence (Level 1); associations with childhood maltreatment, mixed-features, female sex, and type-II BD had moderate evidence (Level 2). Other factors: genetic predisposition, metabolic disturbances or hypothyroidism, antidepressant exposure, predominant depressive polarity (Level 3), along with greater illness duration and immune-inflammatory dysfunction (Level 4) require further study. RC-BD was consistently recognized as having high prevalence (22.3%-35.5% of BD cases) and inferior treatment response. Identified associated factors can inform clinical practice. Long-term illness-course, metabolic factors, and optimal treatment require further investigation.

IMPORTANCE
People with psychosis are more likely to be born and live in densely populated and socioeconomically deprived environments, but it is unclear whether these associations are a cause or consequence of disorder.
OBJECTIVE
To investigate whether trajectories of exposure to deprivation and population density before and after diagnosis are associated with psychotic disorders or nonpsychotic bipolar disorder.
DESIGN, SETTING, AND PARTICIPANTS
This nested case-control study included all individuals born in Sweden between January 1, 1982, and December 31, 2001, diagnosed for the first time with an International Statistical Classification of Diseases and Related Health Problems, Tenth Revision (ICD-10) psychotic disorder or nonpsychotic bipolar disorder between their 15th birthday and cohort exit (December 31, 2016). One sex- and birth year-matched control participant per case was selected. Data analysis was performed from July 2021 to June 2023.
EXPOSURES
The main exposures were quintiles of neighborhood-level deprivation and population density each year from birth to age 14 years and from first diagnosis until cohort exit.
MAIN OUTCOMES AND MEASURES
The main outcomes were the odds of a serious mental illness outcome associated with trajectories of deprivation and population density, before and after diagnosis in cases. Group-based trajectory modeling was used to derive trajectories of each exposure in each period. Logistic regression was used to examine associations with outcomes.
RESULTS
A total of 53 458 individuals (median [IQR] age at diagnosis in case patients, 23.2 [15.0-34.8] years; 30 746 [57.5%] female), including 26 729 case patients and 26 729 control participants, were studied. From birth to early adolescence, gradients were observed in exposure to deprivation and population density trajectories during upbringing and psychotic disorder, with those in the most vs least deprived (adjusted odds ratio [AOR], 1.17; 95% CI, 1.08-1.28) and most vs least densely populated (AOR, 1.49; 95% CI, 1.34-1.66) trajectories at greatest risk. A strong upward mobility trajectory to less deprived neighborhoods was associated with similar risk to living in the least deprived trajectory (AOR, 1.01; 95% CI, 0.91-1.12). Only 543 case patients (2.0%) drifted into more deprived areas after diagnosis; people with psychotic disorder were more likely to belong to this trajectory (AOR, 1.38; 95% CI, 1.16-1.65) or remain in the most deprived trajectory (AOR, 1.36; 95% CI, 1.24-1.48) relative to controls. Patterns were similar for nonpsychotic bipolar disorder and deprivation but weaker for population density.
CONCLUSIONS AND RELEVANCE
In this case-control study, greater exposure to deprivation during upbringing was associated with increased risk of serious mental illness, but upward mobility mitigated this association. People with serious mental illness disproportionately remained living in more deprived areas after diagnosis, highlighting issues of social immobility. Prevention and treatment should be proportionately located in deprived areas according to need.

Review
Atypical antipsychotics are newer second-generation antipsychotics with weak dopamine type 2 blocking but potent 5-HT2 antagonistic activity. They are considered first-line treatments for schizophrenia and gradually replace typical antipsychotics. Extrapyramidal side effects are minimal, and they tend to improve impaired cognitive function in psychotics. Quetiapine fumarate is an atypical antipsychotic drug used to treat schizophrenia, mania and depression in people with bipolar disorder combined with other drugs or alone. Quetiapine was developed in 1985 and approved for medical use in the USA in 1997. Thorough computer-aided literature, surveys revealed that numerous analytical methods were reported over the years. The present study reviews analytical methods with their validation parameters published during the last 22 years (1999-2021) either as a single entity or combination in dosage form, and determination from biological samples. Novel strategies for increasing separation quality, such as QbD analysis and green spectroscopy, were discovered during the evaluation, and this review can be utilized for further research reference.

Meta-Analysis Review
BACKGROUND
Emotion dysregulation (ED) is a transdiagnostic construct characterized by difficulties regulating intense emotions. People with bipolar disorder (BD) are more likely to show ED and use maladaptive emotion regulation strategies than adaptive ones. However, little is known about whether ED in BD is a trait or it is rather an epiphenomenon of mood symptoms.
METHODS
We conducted a systematic review and meta-analysis of the evidence across major literature databases reporting correlations between measures of emotion regulation (overall ED and different emotion regulation strategies) and measures of depressive and (hypo)manic symptoms in BD from inception until April 12th, 2022.
RESULTS
Fourteen studies involving 1371 individuals with BD were included in the qualitative synthesis, of which 11 reported quantitative information and were included in the meta-analysis. ED and maladaptive strategies were significantly higher during periods with more severe mood symptoms, especially depressive ones, while adaptive strategies were lower.
CONCLUSION
ED significantly correlates with BD symptomatology, and it mainly occurs during mood alterations. ED may be a target for specific psychotherapeutic and pharmacological treatments, according to precision psychiatry. However, further studies are needed, including patients with mood episodes and longitudinal design, to provide more robust evidence and explore the causal direction of the associations.
