Purpose: Examine the reliability of field-based fitness assessments in school-aged children with emotional or behavioral difficulties (EBD). Understanding the impact of fitness on physical activity participation for children with EBD is limited by our ability to reliably measure it. Methods: Fifteen children aged 7–12 years with EBD completed 7 assessments—standing broad jump, overhead throw, grip strength, isometric plank hold, isometric wall squat, unilateral heel raise, and modified 6-minute walk test—in a random order on 2 separate occasions. Intraclass correlation coefficients (ICCs) were computed to evaluate reliability. Results: ICCs ranged from.65 to.99 representing moderate to excellent reliability for all assessments. Shorter assessments requiring less attention and behavior regulation tended to demonstrate higher ICC values while assessments with greater attention or behavioral regulation demands tended to have lower ICC values. Conclusion: Results demonstrate varied reliability for fitness tests in children with EBD. Practitioners can use grip strength and standing broad jump assessments with confidence. Other assessments have good reliability but greater variability indicating they may be a challenge for some children with EBD. [ABSTRACT FROM AUTHOR]

There is limited evaluation of approaches to identify patients with new onset bipolar affective disorder (BPAD) when using administrative datasets. Using the Massachusetts All-Payer Claims Database (APCD), we identified individuals with a 2016 diagnosis of bipolar disorder with mania and examined patterns of psychiatric and medical care over the preceding 48 months. Among 4806 individuals aged 15–35 years with a 2016 BPAD with mania diagnosis, 3066 had 48 months of historical APCD data, and of those, 75 % involved information from ≥2 payors. After excluding individuals with historical BPAD or mania diagnoses, there were 583 individuals whose 2016 BPAD with mania diagnosis appeared to be new (i.e., 34 new diagnoses per 100,000 individuals aged 15–35 years). Most individuals received medical care, e.g., 98 % had outpatient visits, 76 % had Emergency Department (ED) visits, and 50 % had mental health-related ED visits during the 48 months prior to their first mania diagnosis. One-third (37.2 %) had a depressive episode before their initial BPAD with mania diagnosis. Study was conducted in one state among insured individuals. We used administrative data, which permits evaluation of large populations but lacks rigorous, well-validated claims-based definitions for BPAD. There could be diagnostic uncertainty during illness course, and clinicians may differ in their diagnostic thresholds. Careful examination of multiple years of patient history spanning all payors is essential for identifying new onset BPAD diagnoses presenting with mania, which in turn is critical to estimating population rates of new disease and understanding the early course of disease. • The rate of new mania diagnoses was 34 per 100,000 individuals. • 97.6 % with new mania had ≥1 outpatient visits in the 48 months prior to diagnosis. • 76.3 % had ED visits, 50.1 % had mental health-related ED visits during that time. • 37.2 % had a depressive episode in the 48 months prior to a new mania diagnosis.

Dynamic gain control of aversive signals enables adaptive behavioral responses. Although the role of amygdalar circuits in aversive processing is well established, the neural pathway for amplifying aversion remains elusive. Here, we show that the brainstem circuit linking the interpeduncular nucleus (IPN) with the nucleus incertus (NI) amplifies aversion and promotes avoidant behaviors. IPN GABA neurons are activated by aversive stimuli and their predicting cues, with their response intensity closely tracking aversive values. Activating these neurons does not trigger aversive behavior on its own but rather amplifies responses to aversive stimuli, whereas their ablation or inhibition suppresses such responses. Detailed circuit dissection revealed anatomically distinct subgroups within the IPN GABA neuron population, highlighting the NI-projecting subgroup as the modulator of aversiveness related to fear and opioid withdrawal. These findings unveil the IPN-NI circuit as an aversion amplifier and suggest potential targets for interventions against affective disorders and opioid relapse. • IPN GABA neurons encode aversive value • The activity of these neurons amplifies aversive responses • The IPN-NI pathway controls aversive evaluation and fear learning • This pathway strengthens the aversive response to opioid withdrawal Liang et al. demonstrate that the brainstem circuit from the interpeduncular nucleus (IPN) to the nucleus incertus (NI) is an aversion amplifier, offering potential therapeutic targets for affective disorders and opioid relapse prevention.

Background: Fibromyalgia (FM) is characterized by widespread chronic pain. Although pain is the main symptom, approximately 90% of patients have depression. This study aimed to analyze the effects of Resistance Training (RT) with low and high intensity on depression in patients with FM. Methods: Thirty-eight women with FM and 31 healthy women were allocated to the low-intensity, high-intensity, preferred-intensity, and control groups. The patients underwent 8 weeks of supervised RT, with two sessions per week of approximately 1 h. The low-intensity resistance training group (LIRT) performed two sets of 12 maximum repetitions. The high-intensity resistance training group (HIRT) performed four sets with six maximum repetitions, and the preferred intensity group (PI) performed three sets, with eight to 12 repetitions, according to the patient's tolerance. The healthy control group did not perform any type of exercise. Depression was assessed using the Beck depression inventory before the start of the intervention, after 4 and 8 weeks. Results: FM patients have higher levels of depression than women without the disease. After 4 weeks, there was a difference in depressive symptoms between the HIRT and LIRT (p = 0.048), and the PI and LIRT (p = 0.048). Conclusion: Prescribing RT with low or high intensity did not significantly reduce depression in patients with FM after 8 weeks, however, analyses between groups after 4 weeks indicated that low-intensity training is more effective than high-intensity training. The prescription of RT exercise to FM could vary among low, high, and preferred intensity, following the patient's tolerance for pain.

Background: Non-suicidal self-injury (NSSI) behaviors among adolescents with mood disorders represent a significant global public health concern. This study aimed to assess the prevalence and identify key predictors of NSSI behaviors in Chinese adolescents diagnosed with depressive or bipolar disorders, addressing a critical gap in the literature. Method: Data from 2343 participants in the Chinese Adolescent Depression Cohort (CADC) were analyzed. The study employed a comprehensive approach, utilizing medical records, clinical assessments, and validated psychometric instruments. Statistical analyses included chi-square tests, logistic regression, and ROC curve analyses, culminating in the development of a predictive nomogram. Results: The prevalence of NSSI behaviors was strikingly high at 73.32%. Significant predictors included female gender (AOR = 2.14, 95% CI [1.70, 2.68]), presence of hallucinations (AOR = 1.52, 95% CI [1.18, 1.97]), borderline personality features (AOR = 1.03, 95% CI [1.01, 1.08]), and childhood trauma (AOR = 1.02, 95% CI [1.01, 1.03]). The study's key contribution is a predictive nomogram with an AUC of 0.74, demonstrating good efficacy in predicting NSSI behaviors. Conclusion: This research reveals an alarmingly high prevalence of NSSI behaviors in Chinese adolescents with mood disorders and identifies critical predictors spanning demographic, clinical, and psychometric domains. The developed nomogram offers a novel approach for risk assessment, highlighting the importance of comprehensive evaluations in adolescent mental healthcare. These findings have significant implications for developing targeted interventions and improving risk assessment strategies in clinical practice. [ABSTRACT FROM AUTHOR]

Here, we investigated the association of different emotion regulation (ER) indices with symptom severity across a large transdiagnostic sample of patients with emotional disorders (cross-sectional approach) and the predictive validity these ER indices have for the outcome of routine care CBT (longitudinal approach). We assessed the trait-like use of adaptive (reappraisal) and maladaptive (suppression, externalizing behaviors) ER strategies via questionnaire as well as the situational ability to regulate emotions with an experimental ER paradigm. Psychopathology was assessed dimensionally using the depression, anxiety, and stress scale. Cross-sectionally symptom severity was predicted by less trait-like use of adaptive and more trait-like use of maladaptive ER strategies, but no associations were found for situational ER ability. This association was more pronounced for depression and stress symptoms rather than anxiety symptoms. In a striking dissociation, the longitudinal analyses revealed the reverse picture: Better situational ER ability, but not trait-like use of ER strategies was associated with less symptom severity after the CBT treatment. Our data argues in favor of a distinction between trait-like and situational ER abilities in individuals with emotional disorders, highlighting challenges in applying adaptive ER strategies in daily life despite demonstrating intact ER skills in experimental settings. Our findings also inform transdiagnostic models of psychopathology and suggest that distress/depression rather than anxiety symptomatology to be driving forces for the occurrence of ER deficits across the depression/anxiety disorders spectrum.

Depression is one of the most common affective disorders in people's life. Women are susceptibility to depression during puberty, peripartum and menopause transition, when they are suffering from sex hormone fluctuation. A lot of studies have demonstrated the neuroprotective effect of estrogen on depression in women, however, the effect of FSH on depression is unclear. In this study, we investigated the role of FSH on depression in mice. Our study demonstrated that FSH induced depression-like behaviors in mice in a dose-dependent manner. This induction was associated with elevated levels of pro-inflammatory cytokines, including IL-1β, IL-6, and TNF- α in both serum and hippocampal tissues. Additionally, FSH treatment resulted in impaired synaptic plasticity and a reduction in the expression of key synaptic proteins. It is noteworthy that the depression-like behaviors, inflammatory cytokines expression and synaptic plasticity impairment induced by FSH could be alleviated by knocking down the expression of FSH receptor (FSHR) in the hippocampus of the mice. Therefore, our findings reveal that FSH may play an important role in the pathogenesis of depression and targeting FSH may be a potential therapeutic strategy for depression during hormone fluctuation in women.

Neuroinflammation that is caused by microglia, the main immune cells of the brain, contributes to neurodegenerative diseases. Psychedelics, including psilocybin and lysergic acid diethylamide (LSD), possess certain anti-inflammatory properties and, therefore, should be considered as drug candidates for treating neuroinflammatory pathologies. When ingested, psilocybin is rapidly dephosphorylated to yield psilocin, which crosses the blood–brain barrier and exerts psychotropic activity by interacting with the 5-hydroxytryptamine 2A receptors (5-HT2ARs) on neurons. Since microglia express all three 5-HT2R isoforms, we hypothesized that, by interacting with these receptors, psilocin beneficially modulates select neuroimmune functions of microglia. We used microglia-like cell lines to demonstrate that psilocin, at non-toxic concentrations, did not affect the secretion of tumor necrosis factor (TNF) by immune-stimulated microglial cells, but significantly inhibited their phagocytic activity, the release of reactive oxygen species (ROS), and nitric oxide (NO) production. The inhibitory activity of psilocin on the latter two functions was similar to that of two selective 5-HT2R agonists, namely, 25I-NBOH and Ro60-0175. The role of this subfamily of receptors was further demonstrated by the application of 5-HT2R antagonists cyproheptadine and risperidone. Psilocin should be considered a novel drug candidate that might be effective in treating neuroimmune disorders, such as neurodegenerative diseases, where reactive microglia are significant contributors.

Background: Physical activities performed under free-living conditions that are unsupervised in the home or community have the potential to modulate non-motor symptoms in people with Parkinson's disease. Objective: This systematic review investigates the relationships between physical activities performed in free-living conditions and non-motor symptoms in people with Parkinson's disease: cognition, anxiety, apathy, depression, sleep disturbances, fatigue, and pain. Data sources: A database search was performed on Scopus, Web of Science, Ovid (PsycINFO), CINAHL, PubMed, and ProQuest (Health and Medicine). Review methods: Observational studies published from 2000 to 2024 that examined the relationships between physical activity and non-motor symptoms were included. The methodological quality of reports was evaluated using critical appraisal checklists appropriate to the study design. Where appropriate, a meta-analysis was conducted to combine data from the included articles. Results: A total of 14 articles met the criteria and used various tools to evaluate non-motor symptoms and physical activity. Meta-analyses showed that people with Parkinson's who are more physically active have better global cognition [ β ranged from 0.12 to 0.28; p = 0.00–0.02] and less affective disorders [ β -0.20, p = 0.00]. Increased physical activity levels were also associated with better sleep quality (n = 1) and less chronic pain (n = 1). The overall methodological quality of the included articles was considered high. Conclusion: Engagement in increased levels of physical activities performed under free-living conditions is associated with better cognition and less anxiety, apathy, and depression in people with Parkinson's disease.

Objective: Major depressive disorder (MDD) is common in childhood, but its etiopathogenesis is still unclear. Published neurochemical studies mostly focus on monoaminergic system, however, the pathophysiology of MDD cannot be explained by monoamine hypothesis only, medications that have effect on monoamines cannot have effect needed in all patients. We aimed to investigate the poliamine pathway of L-arginine metabolism which is proceeding by way of agmatine in adolescents with MDD. Methods: Our study involved 45 patients with MDD (case group), and 44 healthy controls (control group) between the ages of 13-17. Sociodemographic data form, Schedule for Affective Disorders and Schizophrenia for School Age Children-Present and Lifetime Version-DSM-5-Turkish, Beck Depression Inventory (BDI), Spielberger's State-Trait Anxiety Inventory were applied to all subjects. All subjects were evaluated in terms of the levels of serum agmatine, putrescine, spermidine, and spermine. Results: The levels of agmatine and spermine were significantly higher and putrescine and spermidine were significantly lower in case group compared with healthy controls. There was significant negative correlation with the levels of putrescine and spermidine between BDI scores, and there was significant positive correlation between the levels of spermine and BDI scores. No correlation found between the levels of agmatine and BDI scores. Conclusion: These differences that the levels of agmatine and polyamines in the MDD group seem to be a field that worth researching. In the future, the evaluation of the arginine/polyamine metabolism in MDD with larger sample and longitudinal studies is going to capable to contribute to a better understanding of the disorder.

The Japanese Society of Mood Disorders (JSMD) published treatment guidelines of bipolar disorder in 2011. The present guidelines incorporating new findings were developed to comply to the guidelines of the National Academy of Medicine (NAM) by utilizing systematic reviews and meta‐analysis and taking patient and family opinions as well as insights from multiple professional fields into account. They support combination therapy using mood stabilizers and second‐generation antipsychotics in many aspects. They also have limitations, including the grouping of mood stabilizers and second‐generation antipsychotics when meta‐analysis was performed despite their distinct properties, due to the scarcity of drug‐specific evidence. Despite the limitations, these guidelines provide clinical decision support for psychiatrists in Japan. [ABSTRACT FROM AUTHOR]

Objectives The intergenerational stake hypothesis and theories of the life course posit that older generations are invested in the well-being of younger generations. Consistent with this, previous research has shown that adult children's problems are associated with worse parental well-being. Because multigenerational ties have become increasingly important in the 21st century, we propose that adult grandchildren's problems may also impact grandparents' well-being. In this paper, we test this hypothesis and investigate the moderating effects of grandparents' race and maternal/paternal status. Methods The analytic sample includes 206 grandparents aged 65–95 who participated in the second wave of the Family Exchanges Study. Adult grandchildren's problems were operationalized as the proportions of adult grandchildren who experienced (1) physical–emotional problems and (2) lifestyle–behavioral problems. Results Main effects multilevel analyses suggested that adult grandchildren's problems did not predict grandparents' well-being. However, moderation analyses revealed that the association between grandparents' depressive symptoms and adult grandchildren's physical–emotional problems was larger among Black than White grandparents, and maternal than paternal grandparents. Adult grandchildren's lifestyle–behavioral problems did not predict grandparents' depression, and these effects were not conditioned by race or maternal/paternal status. Discussion These findings expand research on the importance of grandparent–adult grandchild relationships and contribute to research on multigenerational relationships and health by considering how problems experienced by members of younger generations affect the psychological well-being of older adults.

Background: Depression and anxiety, the most prevalent neuropsychiatric manifestations in Parkinson's disease (PD), negatively impact their quality of life. Aims: To determine whether the chronic nasal administration of kisspeptin-54 (KP-54) could. Alleviate symptoms of anxiety and depression in hemi-Parkinsonian rats. Study Design: Experimental study. Methods: This study included adult Sprague Dawley male rats who were administered either a vehicle (artificial cerebrospinal fluid) or 6-hydroxydopamine (6-OHDA) unilaterally into the medial forebrain bundle. The vehicle, or KP-54 (3 nmol/kg, applied topically to the rhinarium), was administered daily for a seven-day period. The sucrose preference test (SPT), elevated plus maze test (EPMT), and open field test (OFT) were implemented to evaluate depression- and anxiety-like behaviors, respectively, seven days following the lesion surgery. Gamma-aminobutyric acid (GABA) concentrations in the amygdala were quantified using mass spectrometry. Tyrosine hydroxylase in substantia nigra was analyzed using immunohistochemistry. Results: The nasal delivery of KP-54 significantly reduced depressionand anxiety-like behaviors that were induced by 6-OHDA, as indicated by the results of the SPT, OFT, and EPMT. Moreover, it was observed that nasal KP-54 effectively mitigated 6-OHDA-induced motor deficits and the loss of nigral dopaminergic neurons. The nasal administration of KP- 54 augmented the decline in GABA levels in the amygdala induced by 6-OHDA. Furthermore, effective correlations were established between GABA concentrations and behavioral parameters. Conclusion: The nasal delivery of KP-54 could function as a viable therapeutic alternative for treating mood-related disorders in PD. [ABSTRACT FROM AUTHOR]

Single-case designs substantiate the effectiveness of interventions for people with disabilities and other populations through the repeated measurement of behavior over time. Consequently, employing accurate and reliable systems of measurement is critical to the validity of single-case designs. Much of the data in single-case research are collected through systematic direct observation. Direct observation often involves the use of time sampling, wherein an observer indicates whether a behavior occurred during a specific period. Although scholars have highlighted the potential for time sampling to distort the results of single-case design, targeted reviews indicate time sampling continues to be used in literature involving people with disabilities. The current study reviews literature from the field of special education, in which single-case designs are frequently used to evaluate the efficacy of practices. Using a large, representative sample of 1,425 randomly selected single-case design articles from 33 special education journals, we coded articles to determine the type and features of measurement systems employed by researchers. Findings indicate one-fifth of articles feature some form of time sampling. In addition, time sampling is more prevalent in journals pertaining to individuals with emotional/behavioral disorders. A discussion of implications for research quality follows an overview of results. [ABSTRACT FROM AUTHOR]

Background: Amid the increasing trend and huge impact of mental illness, psychosocial support (PSS) has been asserted to support individuals' recovery. Unfortunately, about 80% of affected people cannot access care as needed. Meanwhile, digital technology has a considerable role in closing service gaps. Aims: This convergent parallel mixed methods study examines existing mental health service utilization, users' needs for PSS, and feasibility of online PSS development. Methods: A cross-sectional interview survey was conducted using a semi-structured questionnaire at a super tertiary psychiatric hospital in Thailand from March to May 2023, with three groups of service users, having self-perceived conditions/diagnosis of schizophrenia (n = 100), mood disorders (n = 84), and others including alcohol and substance use, anxiety and personality disorders (n = 52). Four focus group discussions with three user groups (n = 16) and one multidisciplinary provider group (n = 7) were parallelly executed. Quantitative and qualitative data were convergently analyzed using descriptive and inferential statistics, and thematic and content analysis. Results: Critical shortcomings of PSS were indicated by 75.8% of user participants. Six common types of self-determined PSS were psychoeducational program, support group, skills training, counseling, supported employment, and complimentary therapy. While psychoeducational program was feasible, support group, and counseling were possibly featured within the 'all-at-once' online intervention development. Conclusions: PSS development based on users' needs can promote clinical and personal recovery outcomes, and close the service gaps. Users with mood disorders have the potential for online interventions. Peer-provider formalization, co-production approach, community engagement, digital literacy, infrastructures, and equal access factors are crucial for sustainable development. [ABSTRACT FROM AUTHOR]

Depression is a heterogenous diagnostic construct; however, dynamic interactions between specific depressive symptoms across their qualitatively different profiles remain largely unknown. The study aimed to recognize the most prevalent profiles of depressive symptoms and assess their dynamics in young adults without a history of psychiatric treatment. Depressive symptoms were recorded using the Patient Health Questionnaire-9 (PHQ-9). The data were assessed for all theoretical and empirical combinations of depressive symptoms in participants with a positive screening for depression. The profiles identified in the majority of participants were analyzed using partial correlation and Bayesian networks. Data from 3583 individuals with a positive screening for depression were analyzed. Out of 382 theoretical profiles, 150 profiles (39.3%) were present in this dataset. The majority of participants (56.8%) showed 4 profiles of depressive symptoms including the profile with all depressive symptoms present, the profile without suicidal ideation, the profile without psychomotor impairment, and the profile without both psychomotor impairment and suicidal ideation. The profiles differed largely in terms of their dynamics and symptoms that are necessary to activate the whole network. The network characteristics within specific profiles did not differ significantly across the level of difficulties attributable to depressive symptoms. Our findings indicate that depression emerging in young adults shows a limited number of symptom profiles. However, dynamics of depressive symptoms differs largely between specific profiles regardless of functional impairment indicating the need to personalize therapeutic approaches. Future studies should further disentangle the heterogeneity of depressive symptoms, e.g., by dissecting the symptoms that are combined together by single PHQ-9 items (i.e., hypersomnia and insomnia; psychomotor agitation and retardation).

Background: Pediatric irritability is a pervasive psychiatric symptom, yet its etiology remains elusive. While trauma exposure may contribute to the development of irritability, empirical research is limited. This study examined the prevalence of irritability among trauma‐exposed children, identified factors that differentiate trauma‐exposed children with and without irritability, and employed a network analysis to uncover associations between irritability and trauma exposure in the family unit. Methods: Sample included 676 children (56.3% male, mean age = 9.67 ± 3.7 years) and their parents referred by the Connecticut Department of Children and Families to Fathers for Change – a psychotherapy intervention designed to reduce intimate partner violence (IPV) and child maltreatment. Child's trauma exposure, post‐traumatic stress disorder (PTSD) symptoms, and irritability were assessed pre‐intervention using self‐ and caregiver‐report. Parents self‐reported their childhood and adulthood trauma exposures, PTSD symptoms, irritability, psychopathology, and IPV. Results: Across caregiver‐ and child‐reports, 16%–17% of children exhibited irritability. Irritable children experienced greater trauma exposure, interpersonal violence, emotional abuse, and PTSD severity. They had caregivers, particularly mothers, with greater trauma histories, IPV, and psychopathology. Network analysis revealed 10 nodes directly correlated to child's irritability including child's PTSD severity, parental IPV (specifically psychological violence), and parental psychopathology. Conclusions: Results provide initial empirical evidence that pediatric irritability is linked to trauma exposure, suggesting trauma histories be considered in the diagnosis and treatment of irritability. Interventions addressing caregiver trauma, IPV, and psychopathology may ameliorate pediatric irritability. Future studies could benefit from adopting network approaches with longitudinal or time series data to elucidate causality and points of intervention. [ABSTRACT FROM AUTHOR]

Background: Offspring of parents with affective disorders (OAD) are at risk of developing a wide range of mental disorders. Deficits in the rearing environment and high levels of stress are well‐known risk factors for negative outcomes in OAD. Building on prior research, we aim to examine the longitudinal relationships between family dysfunction, stressful life events, and mental health in OAD and control offspring of parents with no affective disorder. In the present study, we hypothesized that high levels of family dysfunction would be associated with more internalizing and externalizing problems across time in OAD than in controls, and that family dysfunction would mediate the relationship between stressful life events in adolescence and poor mental health in adulthood, particularly in OAD. Methods: As part of the TRacking Adolescents' Lives Survey (TRAILS), 2230 participants (51% female, Mage = 11.1 years, SD = 0.6, at baseline) and their parents completed measures across six time points, spanning 15 years. Mental health, family dysfunction, and stressful life events were assessed with the Youth and Adult Self‐Report, Family Assessment Device, and an in‐house measure, respectively. Results: Multi‐group structured equation modeling revealed that family dysfunction was linked to internalizing and externalizing problems in OAD, but not controls, across time. Risk status did not moderate family dysfunction's mediation of the relationship between stressful life events and negative outcomes in adulthood. Conclusions: OAD show high sensitivity to dysfunction in the rearing environment across childhood and adolescence, which supports the use of family based interventions to prevent the development of mental disorders in high‐risk youth.

Objective: Studies using proton magnetic resonance spectroscopy reveal substantial inconsistencies in the levels of brain glutamate, glutamine and glutamate + glutamine across schizophrenia spectrum disorders. This systematic review employs qualitative and quantitative methods to analyse the patterns and relationships between glutamatergic metabolites, schizophrenia spectrum disorders and brain regions. Methods: A literature search was conducted using various databases with keywords including glutamate, glutamine, schizophrenia, psychosis and proton magnetic resonance spectroscopy. Inclusion criteria were limited to case-control studies that reported glutamatergic metabolite levels in adult patients with a schizophrenia spectrum disorder diagnosis – i.e. first-episode psychosis, schizophrenia, treatment-resistant schizophrenia and/or ultra-treatment-resistant schizophrenia – using proton magnetic resonance spectroscopy at 3 T or above. Pooled study data were synthesized and analysed. Results: A total of 92 studies met the inclusion criteria, including 2721 healthy controls and 2822 schizophrenia spectrum disorder participants. Glu levels were higher in the basal ganglia, frontal cortex and medial prefrontal of first-episode psychosis participants, contrasting overall lower levels in schizophrenia participants. For Gln, strong differences in metabolite levels were evident in the basal ganglia, dorsolateral prefrontal cortex and frontal cortex, with first-episode psychosis showing significantly higher levels in the basal ganglia. In glutamate + glutamine, higher metabolite levels were found across schizophrenia spectrum disorder groups, particularly in the basal ganglia and dorsolateral prefrontal cortex of treatment-resistant schizophrenia participants. Significant relationships were found between metabolite levels and medication status, clinical measures and methodological variables. Conclusion: The review highlights abnormal glutamatergic metabolite levels throughout schizophrenia spectrum disorders and in specific brain regions. The review underscores the importance of standardized future research assessing glutamatergic metabolites using proton magnetic resonance spectroscopy due to considerable literature heterogeneity.

Deficits in positive emotion regulation skills may be an important factor in the development and maintenance of anxiety and mood disorders. A treatment, which includes strategies to build and strengthen positive emotion regulation skills has been provided to patients primarily diagnosed with an anxiety and or mood disorder in an adult mental health outpatient service setting. To study the effects on positive and negative emotion, emotion regulation skills, emotional disorder symptoms, quality of life, and wellbeing during a new developed treatment. An exploratory clinical trial was used to conduct a preliminary assessment of a novel intervention. The intervention was provided in a group format over a 6-week period and independent practice over an 8-week period. Outcome variables were assessed pre- and post-treatment and at a 2-month follow up. Life quality, subjective wellbeing ratings, depressive and anxiety symptoms improved at follow up. The data suggests that the intervention may have the potential to produce desired change in positive emotion regulation. Preliminary findings suggest the intervention can have beneficial effects. These findings are promising and support the possibility that disturbances in positive emotion regulation may be a generative target for treatment research. [ABSTRACT FROM AUTHOR]

Objectives: To assess the feasibility of universal screening of postpartum depression (PPD), using the Edinburgh Postpartum Depression Scale (EPDS) in the general population. To investigate the proportion of women identified as being at risk of PPD and with confirmed PPD or other mental disorders after a psychiatric consultation. Methods: A multicenter prospective cohort study in four French maternities conducted between 2020 and 2023. All women aged over 18 years, who delivered following a singleton pregnancy after 37 weeks of gestation were eligible for inclusion. The exclusion criteria were pre‐existing psychiatric disorders such as depressive syndrome. The EPDS was completed at 8 weeks postpartum via an online self‐administered questionnaire. If the response to the questionnaire suggested a mental disorder, a psychiatric consultation was proposed to the women concerned. The endpoints were the proportion of women completing the EPDS, the EPDS score, the proportion of women at risk of PPD, the proportion of psychiatric consultation, and the subsequent diagnosis. Results: The study included 923 women, of whom 55.0% (508/923) completed the EPDS. Among them, 28.1% (143/508) had an EPDS score of 10 or more, and 11.2% (57/508) received a psychiatric consultation. PPD was confirmed in 8.8% (5/57) of women. Other disorders detected were mood disorders, disorders specifically associated with stress, and anxiety/fear‐related disorders, in 33.3%, 28.1%, and 14.0% of the women, respectively. Conclusions: Screening with self‐administered EPDS is feasible, with a good response rate, making it possible to suspect mental disorders, including PPD, and to offer psychological support when needed. Synopsis: Screening with EPDS self‐administered is feasible with a good response rate, making it possible to suspect mental disorders and to offer psychological support when needed.

Aim: To clarify the concept of fear of childbirth among pregnant women and to examine its current measure tools. Background: Fear of childbirth is a psychological symptom, prevalent among pregnant women, which negatively impacts women's health and well‐being. It has become an increasingly concerning issue in perinatal mental health. However, due to its poor conceptualization, it presents difficulty in conducting reliable assessments and identifying risk factors. Methods: The Walker and Avant approach to concept analysis guided this review. Six bibliographic databases were systematically searched for published research from their inception date to May 2023. Additional records were identified by manually searching the reference lists of relevant studies. Quantitative and qualitative studies investigating fear of childbirth in pregnant women were included. Results: Three critical attributes have been identified: cognitive impairments, affective disorders and somatic symptoms. Antecedents include perceived a real or anticipated threat of pregnancy or its outcomes, low perceived self‐coping ability and unmet social support needs. Consequences include processing and avoiding behaviours. This study also identified the dimensions of fear of childbirth, including 6 primary categories and 14 subcategories. The content of five scales was analysed and none covered all domains. Conclusions: The current analysis provides healthcare providers with a more comprehensive framework to assess and identify fear of childbirth. Further research is needed to develop a suitable instrument that covers all the attributes and dimensions of this concept and assesses its severity. Impact: This conceptual analysis provides a comprehensive insight into the phenomenon of fear of childbirth. This will help family members, healthcare providers and policymakers to identify the psychological needs of pregnant women and improve the quality of antenatal care. Patient or Public Contribution: Not applicable as no new data were generated. [ABSTRACT FROM AUTHOR]

Encephalopathy is part of the clinical triad of Susac syndrome, but a detailed understanding of the neurocognitive and neuropsychiatric profile of this condition is lacking. Existing literature indicates that cognitive deficits range in severity from subtle to profound. Executive function and short-term recall are affected frequently. Psychiatric manifestations may be absent or may include anxiety, mood disorders or psychosis. If psychiatric phenomena develop during the disease course, it can be hard to disentangle whether symptoms directly relate to the pathology of Susac syndrome or are secondary to treatment-related side effects. In this article, we review what is known about the cognitive and psychiatric morbidity of Susac syndrome and identify areas where knowledge is deficient. Importantly, we also provide a framework for future research, arguing that better phenotyping, understanding of pathophysiology, evaluation of treatments on cognitive and psychiatric outcomes, and longitudinal data capture are vital to improving patient outcomes.

Background: Postpartum psychotic‐ or mood disorders are psychiatric emergencies associated with risk of suicide and infanticide. Except from case reports, there are only few descriptions of its treatment. Therefore, we aimed to describe the treatment of women admitted with postpartum psychotic‐ or mood disorder in Denmark with emphasis on the use of electroconvulsive therapy (ECT). Methods: We conducted a register‐based cohort study of all women with incident postpartum psychotic‐ or mood disorder (no prior diagnoses of psychotic‐ or mood disorder or treatment with ECT) requiring admission in the period from 2011 to 2018. For these patients, we described the treatment and the 6‐month readmission risk. Results: We identified 91 women with postpartum psychotic‐ or mood disorder with a median admission length of 27 days (interquartile range: 10–45). Of those, 19% received ECT with a median time from admission to first ECT of 10 days (interquartile range: 5–16). The median number of ECT sessions was eight (interquartile range: 7–12). In the 6 months following discharge, 90% of the women received some form of psychopharmacological treatment (62% antipsychotics, 56% antidepressants, 36% anxiolytics/sedatives, 19% lithium, and 9% mood stabilizing antiepileptics), and 31% were readmitted. Conclusion: Psychiatric admission for incident postpartum psychotic‐ or mood disorder is rare in Denmark. Among those admitted, ECT and psychopharmacological treatment is commonly used. The 6‐month readmission risk is high, warranting close follow‐up. The fact that there is no international consensus on the optimal treatment of postpartum psychotic‐ or mood disorder is problematic and calls for action. [ABSTRACT FROM AUTHOR]

Objective: To assess the postpartum depression (PPD) risk in women with postpartum hemorrhage (PPH) and moderators. Methods: We identified observational studies of PPD rates in women with versus without PPH in Embase/Medline/PsychInfo/Cinhail in 09/2022. Study quality was evaluated using the Newcastle‐Ottawa‐Scale. Our primary outcome was the odds ratio (OR, 95% confidence intervals [95%CI]) of PPD in women with versus without PPH. Meta‐regression analyses included the effects of age, body mass index, marital status, education, history of depression/anxiety, preeclampsia, antenatal anemia and C‐section; subgroup analyses were based on PPH and PPD assessment methods, samples with versus without history of depression/anxiety, from low‐/middle‐ versus high‐income countries. We performed sensitivity analyses after excluding poor‐quality studies, cross‐sectional studies and sequentially each study. Results: One, five and three studies were rated as good‐, fair‐ and poor‐quality respectively. In nine studies (k = 10 cohorts, n = 934,432), women with PPH were at increased PPD risk compared to women without PPH (OR = 1.28, 95% CI = 1.13 to 1.44, p < 0.001), with substantial heterogeneity (I2 = 98.9%). Higher PPH‐related PPD ORs were estimated in samples with versus without history of depression/anxiety or antidepressant exposure (OR = 1.37, 95%CI = 1.18 to 1.60, k = 6, n = 55,212, versus 1.06, 95%CI = 1.04 to 1.09, k = 3, n = 879,220, p < 0.001) and in cohorts from low‐/middle‐ versus high‐income countries (OR = 1.49, 95%CI = 1.37 to 1.61, k = 4, n = 9197, versus 1.13, 95%CI = 1.04 to 1.23, k = 6, n = 925,235, p < 0.001). After excluding low‐quality studies the PPD OR dropped (1.14, 95%CI = 1.02 to 1.29, k = 6, n = 929,671, p = 0.02). Conclusions: Women with PPH had increased PPD risk amplified by history of depression/anxiety, whereas more data from low‐/middle‐income countries are required. [ABSTRACT FROM AUTHOR]

Aim: As most substance use prevention programs are offered at school, it is important to explore which group of students might be at increased risk. Both researchers and educators have often maintained that students with special educational needs due to emotional and behavioral disorders (SENs-EBD) are particularly vulnerable. Hence, the aim of the current systematic review was to examine the alcohol and cannabis use by students with SENs-EBD in comparison to students without SENs or other types of SENs. Methods: Adhering to the PRISMA guidelines, the review was registered on PROSPERO (CRD42023375799) and search terms were entered in Web of Science, Scopus, ERIC, and PubMed in December 2022. Publications were required to report on empirical quantitative studies (primary data) that assessed alcohol and/or cannabis use by adolescent students with SENs-EBD and a comparison group, and be published in English-language journal articles, conference papers, or book chapters from 2000 onwards. The QuADS tool was used for quality assessment. Results: Based on these criteria, six articles (sample sizes N = 61 to N = 122,180) were included for the thematic narrative synthesis. The studies revealed that the percentage of students with SENs-EBD consuming alcohol and cannabis was higher compared to students who did not have SENs or attended mainstream schools. Conclusion: The small number of heterogeneous studies, with limitations concerning the sample size, missing effect sizes, and influence of control variables, demonstrates the need for more research. The systematic review provides guidance for such future research endeavors, as well as preliminary notions for practical implications. [ABSTRACT FROM AUTHOR]

Although studies have highlighted the role played by couple and parental relationships for children's psychosocial adjustment, especially in challenging situations, research on these two relationship domains has largely developed separately and mostly focussed on negative couple processes. However, Family Systems Theory highlights how these subsystems are interconnected, and studies inspired by this theoretical framework provide evidence of how the quality of the interparental relationship predicts the parent–child relationship. This study focussed on the association between two relational resources (dyadic coping and parent–child relationship quality) and children's emotional difficulties during the outbreak of the COVID‐19 pandemic in Italy. Five hundred ninety‐one Italian parents filled in an online self‐report questionnaire. A path analysis model was estimated to test the mediating role of parent–child relationship quality in the association between partner positive dyadic coping and children's emotional difficulties. The findings showed both a direct effect and an indirect effect of partner positive dyadic coping on children's emotional difficulties, because parent–child relationship quality partially mediated this association. Enhancing parents' ability to cope together with stress and the quality of the parent–child relationship might contribute to decrease children's vulnerability to emotional difficulties in challenging times.

• Bifidobacterium dentium reduces prenatal stress-induced reductions in gestational weight gain. • B. dentium has intergenerational effects on inflammation, reducing maternal CCL2 and offspring IL6. • Indole-3-propionic acid and kynurenic acid levels are increased in both dam and offspring by B. dentium. • Gestationally-administered B. dentium improves social behavior outcomes in adult offspring. Prenatal stress (PNS) profoundly impacts maternal and offspring health, with enduring effects including microbiome alterations, neuroinflammation, and behavioral disturbances such as reductions in social behavior. Converging lines of evidence from preclinical and clinical studies suggest that PNS disrupts tryptophan (Trp) metabolic pathways and reduces gut Bifidobacteria, a known beneficial bacterial genus that metabolizes Trp. Specifically, previous work from our lab demonstrated that human prenatal mood disorders in mothers are associated with reduced Bifidobacterium dentium in infants at 13 months. Given that Bifidobacterium has been positively associated with neurodevelopmental and other health benefits and is depleted by PNS, we hypothesized that supplementing PNS-exposed pregnant dams with B. dentium would ameliorate PNS-induced health deficits. We measured inflammatory outputs, Trp metabolite levels and enzymatic gene expression in dams and fetal offspring, and social behavior in adult offspring. We determined that B. dentium reduced maternal systemic inflammation and fetal offspring neuroinflammation, while modulating tryptophan metabolism and increasing kynurenic acid and indole-3-propionic acid intergenerationally. Additional health benefits were demonstrated by the abrogation of PNS-induced reductions in litter weight. Finally, offspring of the B. dentium cohort demonstrated increased sociability in males primarily and increased social novelty primarily in females. Together these data illustrate that B. dentium can orchestrate interrelated host immune, metabolic and behavioral outcomes during and after gestation for both dam and offspring and may be a candidate for prevention of the negative sequelae of stress.

Alcohol use disorder (AUD) is a major public health concern that despite its prevalence, lacks a widely-effective treatment due to the complexity of AUD pathology. AUD is highly comorbid with other psychiatric conditions including anxiety and mood disorders, however it is unclear how these disorders influence each other. The underlying etiology of these comorbidities is difficult to decipher and factors including sex, stress, and the environment further complicate both diagnosis and treatment strategies. To understand more about this bidirectional relationship between AUD and comorbid psychiatric disorders, we ran male and female C57Bl/6j mice through baseline behavioral testing followed by intermittent access-two bottle choice (IA-2BC) drinking. We found no sex differences in basal anxiety-like or depressive-like behavior, however females displayed enhanced motivated feeding behavior. Females consumed more ethanol than males, at both 1hr and 24hr timepoints. Basal affective state did not predict subsequent ethanol intake in either sex, however exploratory behavior was positively correlated with drinking in males but not females. We then re-assessed negative affect behavior following chronic ethanol drinking to determine if drinking impacted subsequent affective behavior and found no relationship between ethanol intake and affective state in males or females. We also examined how chronic ethanol drinking affected central amygdala (CeA) and basolateral amygdala (BLA) neuronal activity in males and females. Ethanol-drinking females had a decrease in CeA neuronal activity, driven by reduced activity in the lateral (CeA l) sub-region, while in males there was no significant difference in CeA activity compared to water controls. Neither males or females had a significant change in BLA neuronal activity following chronic ethanol drinking. Collectively, these results demonstrate sex differences in basal motivated behavior, drinking behavior, and subregion-specific amygdala neuronal activity following chronic ethanol drinking which may inform the sex differences seen in patients diagnosed with AUD and comorbid conditions. • There were no basal sex differences in affective behavior. • Basal affective behavior did not determine future ethanol intake. • Chronic ethanol drinking did not alter subsequent affective behavior. • CeA activity was reduced in ethanol-exposed females compared to water controls. • BLA activity did not differ between male and female ethanol and water groups.

Growing evidence suggests the relevance of affective temperaments in the development of mood disorders. This study aims to assess their potential role as a vulnerability factor for seasonal affective disorder (SAD) and subsyndromal SAD (S-SAD) in a sample of young individuals without a history of clinical diagnosis. Eight hundred and forty-six university students were enrolled in a cross-sectional study. Participants were evaluated for exclusion and inclusion criteria and divided into Control, S-SAD, and SAD groups. They filled out two self-administered questionnaires to assess the degree of seasonality problems and the predominant type of affective temperaments, the Seasonal Pattern Assessment Questionnaire (SPAQ), and the Temperament Evaluation Instrument of Memphis, Pisa, Paris, and San Diego-Auto-questionnaire version scale (briefTEMPS-M version). We conducted a multinomial logistic regression model to explore the relationship between affective temperaments and seasonality. Our results evidenced that cyclothymic [χ2 (2) = 33.486, p < 0.001] and anxious [χ2 (2) = 86.991, p < 0.001] temperaments were significant predictors in the model, suggesting that individuals with cyclothymic and anxious temperaments are at increased risk of developing SAD, due to heightened seasonal changes in mood and behavior. In contrast, people with hyperthymic temperament appear less susceptible to experiencing seasonal problems. The homogeneity of the sample; only retrospective self-reported data were considered; measures of temperament and seasonality were simultaneously assessed. Understanding which affective temperaments may constitute a potential predisposing factor for vulnerability to seasonal changes can aid in better assessing SAD and predicting its outcome. [Display omitted] • Environmental changes associated with seasonal variations impact human behavior and mood. • Seasonal affective disorder (SAD) is a condition characterized by recurrent seasonal depression. • Cyclothymic and anxious temperaments are a factor of risk for SAD. • A comprehensive psychological evaluation is essential to managing and treating SAD.

Severe depression, anxiety, and mood dysregulation during pregnancy and postpartum are risk factors for the safety and health of mother and baby. Current best practice guidelines recommend screening for depressive and anxiety symptoms before and during pregnancy, in addition to the postpartum period. Rapid identification and treatment of depression has the potential to be life-saving and prevent deleterious consequences, including impaired mother–infant bonding, emotional dysregulation, and other developmental problems. The current article reviews the neurobiological mechanisms of postpartum depression and a novel rapidly acting oral pharmacotherapeutic neuroactive steroid, zuranolone.

Introduction: Bipolar disorder is a psychiatric condition characterized by the coexistence of depression and mania. Diagnosis of this disorder can be challenging due to limited pathologic and experimental tools. Treatment compliance is often poor due to medication side effects. Although cathepsin is known to play a significant role in diseases such as tumors and osteoporosis, its role in psychiatric disorders is not yet fully understood. Objective: The aim of this study was to investigate the relationship between cathepsin in the blood circulation and bipolar disorder. Methods: The causal relationship between cathepsin and different subtypes of bipolar affective disorder was explored using bidirectional Mendelian randomization analysis and multivariate analysis. Results: It was found that cathepsin H level was a protective factor for type II bipolar disorder. No potential causal relationship was found between cathepsin H and type I bipolar disorder, but cathepsin B changes with the development of type I bipolar disorder. A causal relationship was found between cathepsin H and cerebral dopamine neurotrophic factor. Conclusions: In conclusion, cathepsin H may be a diagnostic target for bipolar II disorder and may play a guiding role in clinical diagnosis. Cathepsin H may have an effect on BD through cerebral dopamine neurotrophic factor. [ABSTRACT FROM AUTHOR]

The microcircuitry within superficial layers of the dorsolateral prefrontal cortex (DLPFC), composed of excitatory pyramidal neurons and inhibitory GABAergic interneurons, has been suggested as the neural substrate of working memory performance. In schizophrenia, working memory impairments are thought to result from alterations of microcircuitry within the DLPFC. GABAergic interneurons, in particular, are crucially involved in synchronizing neural activity at gamma frequency, the power of which increases with working memory load. Alterations of GABAergic interneurons, particularly parvalbumin (PV) and somatostatin (SST) subtypes, are frequently observed in schizophrenia. Abnormalities of GABAergic neurotransmission, such as deficiencies in the 67 kDA isoform of GABA synthesis enzyme (GAD67), vesicular GABA transporter (vGAT), and GABA reuptake transporter 1 (GAT1) in presynaptic boutons, as well as postsynaptic alterations in GABAA receptor subunits further contribute to impaired inhibition. This review explores GABAergic abnormalities of the postmortem DLPFC in schizophrenia, with a focus on the roles of interneuron subtypes involved in cognition, and GABAergic neurotransmission within presynaptic boutons and postsynaptic alterations. Where available, comparisons between schizophrenia and affective disorders that share cognitive pathology such as bipolar disorder and major depressive disorder will be made. Challenges in directly measuring GABA levels are addressed, emphasizing the need for innovative techniques. Understanding GABAergic abnormalities and their implications for neural circuit dysfunction in schizophrenia is crucial for developing targeted therapies. [ABSTRACT FROM AUTHOR]

Background: Although repeatedly confirmed, the molecular nature of gene-environment (GxE) interactions has rarely been investigated in the clinical context of mood disorders. This study assesses the relationship between HTR2A genetic variants and the modulatory effect of inflammation in a collective cohort of patients with major depressive disorder (MDD) and bipolar disorder (BD), as a unified group with two distinct phenotypes. Methods: The study included 138 patients with acute mood episodes (BD = 83; MDD = 55). HTR2A rs6313 and rs6314 genotyping was performed while measuring platelet-derived indicators of inflammation (platelet count (PLT), mean platelet volume (MPV), plateletcrit, and platelet distribution width) and the MPV/PLT ratio. Results: The HTR2A rs6313 variant is a significant predictor of the polarity phenotype in mood disorders, with the MPV/PLT ratio moderating this relationship, but only under low-inflammatory conditions. In more pronounced inflammatory states, genetic influences lose their predictive role. Conclusions: To our knowledge, this is the first study to investigate the complex interplay between platelet-derived indicators of inflammation and HTR2A variants in the context of mood disorders. Without pro-inflammatory conditions, mood disorders seem to be more genetically determined. Under pro-inflammatory conditions, phenotypic presentation is less dependent on genetic factors. GxE interactions in mood disorders are multifaceted, context-dependent and relevant for assessing their clinical presentation and course. [ABSTRACT FROM AUTHOR]

AbstractObjectiveMethodResultsConclusions\nHIGHLIGHTSPoor sleep quality exacerbates suicidal ideation. Depression, anxiety, and stress may play important roles in this relationship. However, the underlying mechanisms remain unknown.A total of 2,598 young men were recruited for a cross-sectional study focusing on a range of sociodemographic factors, emotions, sleep quality, and suicidal ideation. Parallel, serial, and moderated mediation models were used to determine whether depression, anxiety, and stress mediated the relationship between poor sleep quality and suicidal ideation.Direct and indirect effects of poor sleep quality on suicidal ideation were observed. Depression, anxiety, and stress mediated the relationship between poor sleep quality and suicidal ideation (βDepression = 0.166, 95% confidence interval [CI]: 0.144, 0191; βAnxiety = 0.153, 95% CI: 0.130, 0.177; βStress = 0.176, 95% CI: 0.154, 0.200). The serial mediation model indicated that depressive and stress symptoms co-play a serial mediating role in the relationship between poor sleep quality and suicidal ideation (βa = 0.049, 95% CI: 0.036, 0.062; βb = 0.099, 95% CI: 0.080, 0.120). The moderated mediation model revealed that the mediating role of stress on the relationship between poor sleep quality and suicidal ideation was moderated by depression (β = 0.173, 95% CI: 0.150, 0.197). Self-reported measures and the study’s cross-sectional design preclude the causal inferences reported.The findings of this study prompt clinical and scientific researchers to consider the interplay among affective disorders when investigating etiological and psychological factors that may contribute to suicidal ideation.Poor sleep quality is associated with increased levels of suicidal ideation.Sleep disturbances are among the well-known risk factors for suicidal ideation.Poor sleep quality impairs critical processes involved in affective functioning.

The amygdala and raphe nuclei, which play crucial roles in mood regulation, are influenced by serotonergic neurotransmission. Alterations in this neurotransmission are associated with mood disorders. Therefore, using immunohistochemistry and quantitative methods this study was designed to evaluate potential alterations in the expression of serotoninergic markers in the amygdala and raphe nuclei of mice with oestrogen receptor β (ERβ) knock out which exhibit increased anxiety as evidenced by reduced locomotion and increased thigmotaxis. These alterations could either contribute to heightened anxiety or serve as a compensatory strategy for reducing it. The results show that in ERβ knock‐out mice, 5‐HT1B expression is significantly increased in the amygdala, while 5‐HTT expression is significantly decreased in both the amygdala and raphe nuclei. Furthermore, ERβ deficiency does not affect TPH2. In conclusion, serotonin signalling is altered in the amygdala and raphe nuclei of ERβ knock‐out females. It seems that an increase in 5‐HTT levels has been associated with reduced anxiety, whereas a decrease in 5‐HT1B receptors may encourage fear. However, further studies are required to determine the exact role of ERβ in anxiety‐related behaviour. [ABSTRACT FROM AUTHOR]

Summary Neuroinflammation, characterized by a complex interplay among innate and adaptive immune responses within the central nervous system (CNS), is crucial in responding to infections, injuries, and disease pathologies. However, the dysregulation of the neuroinflammatory response could significantly affect neurons in terms of function and structure, leading to profound health implications. Although tremendous progress has been made in understanding the relationship between neuroinflammatory processes and alterations in neuronal integrity, the specific implications concerning both structure and function have not been extensively covered, with the exception of perspectives on glial activation and neurodegeneration. Thus, this review aims to provide a comprehensive overview of the multifaceted interactions among neurons and key inflammatory players, exploring mechanisms through which inflammation influences neuronal functionality and structural integrity in the CNS. Further, it will discuss how these inflammatory mechanisms lead to impairment in neuronal functions and architecture and highlight the consequences caused by dysregulated neuronal functions, such as cognitive dysfunction and mood disorders. By integrating insights from recent research findings, this review will enhance our understanding of the neuroinflammatory landscape and set the stage for future interventions that could transform current approaches to preserve neuronal integrity and function in CNS‐related inflammatory conditions.

Adolescents who have experienced harsh parenting face an increased risk of developing Internet addiction (IA) later in life. Few studies have examined the underlying mechanisms between harsh parenting and IA. This study explores the relationship between harsh parenting and IA, focusing on associations with emotional regulation difficulties and maladaptive cognitions. The study group consisted of 925 adolescents (Mage = 16.16, SDage = 0.72; 48.54% girls) who were recruited to complete a survey measuring the variables of harsh parenting, difficulties in emotional regulation, maladaptive cognitions, and IA. After accounting for age and gender, it was found that harsh parenting is directly associated with adolescents' IA (β = 0.07, p < 0.01). The chain mediating effect of emotional regulation difficulties and maladaptive cognitions was 0.08 (95% CI [0.06, 0.10]), which implies that a chain mediation was identified between harsh parenting and IA through the intermediary factors of emotional regulation difficulties and maladaptive cognitions. The findings suggest that addressing the emotional regulation difficulties and maladaptive cognitions could be important aspects to consider in interventions and prevention efforts aimed at reducing adolescent IA.

Background Methods Results Conclusions Symptoms related to mood and anxiety disorders (emotional disorders) often present in childhood and adolescence. Some of the genetic liability for mental disorders, and emotional and behavioral difficulties seems to be shared. Yet, it is unclear how genetic liability for emotional disorders and related traits influence trajectories of childhood behavioral and emotional difficulties, and if specific developmental patterns are associated with higher genetic liability for these disorders.This study uses data from a genotyped sample of children (n = 54,839) from the Norwegian Mother, Father, and Child Cohort Study (MoBa). We use latent growth models (1.5–5 years) and latent profile analyses (1.5–8 years) to quantify childhood trajectories and profiles of emotional and behavioral difficulties and diagnoses. We examine associations between these trajectories and profiles with polygenic scores for bipolar disorder (PGSBD), anxiety (PGSANX), depression (PGSDEP), and neuroticism (PGSNEUR).Associations between PGSDEP, PGSANX, and PGSNEUR, and emotional and behavioral difficulties in childhood were more persistent than age‐specific across early childhood (1.5–5 years). Higher PGSANX and PGSDEP were associated with steeper increases in behavioral difficulties across early childhood. Latent profile analyses identified five profiles with different associations with emotional disorder diagnosis. All PGS were associated with the probability of classification into profiles characterized by some form of difficulties (vs. a normative reference profile), but only PGSBD was uniquely associated with a single developmental profile.Genetic risk for mood disorders and related traits contribute to both a higher baseline level of, and a more rapid increase in, emotional and behavioral difficulties across early and middle childhood, with some indications for disorder‐specific profiles. Our findings may inform research on developmental pathways to emotional disorders and the improvement of initiatives for early identification and targeted intervention. [ABSTRACT FROM AUTHOR]

Background: Fluoroquinolones are broad-spectrum antibiotics with significant antimicrobial activity. Despite their therapeutic benefits, they are associated with a range of adverse drug reactions (ADRs), particularly those affecting the central nervous system (CNS). This study aimed to analyze the psychiatric ADRs linked to fluoroquinolones using data from the FDA Adverse Event Reporting System (FAERS) database. Methods: A retrospective pharmacovigilance study was conducted using FAERS data from Q1 2004 to Q4 2023. The data processing phase involved the FDArecommended deduplication method, and ADRs were classified according to Medical Dictionary for Regulatory Activities (MedDRA). Disproportionality analysis was performed using the reporting odds ratio (ROR), and statistical significance was assessed using the Chi-square test or Fisher's exact test. Results: The study identified 84,777 reports associated with fluoroquinolones, with 359,480 Preferred Terms-annotated entries, 27,816 of these reports were psychiatric ADRs. Mood disorders were the most frequently reported, including anxiety, depression, and delirium, with some reports escalating to suicidal ideation and behaviors. The Standardized MedDRA Query classification system was used to categorize these ADRs into Depression, Suicide/self-injury, Psychosis and psychotic disorders, and Non-infectious encephalopathy/delirium. Ciprofloxacin was most frequently linked to depression and suicidal ideation, while moxifloxacin showed a robust correlation with delirium. The risk of psychiatric ADRs varied by age group, with affective disorders more prevalent in adults under 65 and psychosis and delirium in those over 65. Conclusion: Fluoroquinolones are associated with a range of psychiatric ADRs, with notable differences between the drugs in the class. The study highlights the need for caution in prescribing fluoroquinolones, particularly for patients with pre-existing mental health conditions or those in higher risk age groups. The findings also underscore the importance of considering age-specific preventive strategies when administering these antibiotics. [ABSTRACT FROM AUTHOR]

ABSTRACT Mobile health studies often collect multiple within‐day self‐reported assessments of participants' behavior and well‐being on different scales such as physical activity (continuous scale), pain levels (truncated scale), mood states (ordinal scale), and the occurrence of daily life events (binary scale). These assessments, when indexed by time of day, can be treated and analyzed as functional data corresponding to their respective types: continuous, truncated, ordinal, and binary. Motivated by these examples, we develop a functional principal component analysis that deals with all four types of functional data in a unified manner. It employs a semiparametric Gaussian copula model, assuming a generalized latent non‐paranormal process as the underlying generating mechanism for these four types of functional data. We specify latent temporal dependence using a covariance estimated through Kendall's τ$$ \tau $$ bridging method, incorporating smoothness in the bridging process. The approach is then extended with methods for handling both dense and sparse sampling designs, calculating subject‐specific latent representations of observed data, latent principal components and principal component scores. Simulation studies demonstrate the method's competitive performance under both dense and sparse sampling designs. The method is applied to data from 497 participants in the National Institute of Mental Health Family Study of Mood Spectrum Disorders to characterize differences in within‐day temporal patterns of mood in individuals with the major mood disorder subtypes, including Major Depressive Disorder and Type 1 and 2 Bipolar Disorder. Software implementation of the proposed method is provided in an R‐package. [ABSTRACT FROM AUTHOR]

Introduction: Hallucinations are serious symptoms that can lead to high levels of distress, functional impairment, and increased risk of suicide in both adults and children. However, their etiology and treatment remain unclear. Hallucinations and sensory processing difficulties (SPDs) are associated with various psychiatric disorders, including mood, anxiety, and post-traumatic stress disorder. This study aimed to investigate the potential association between hallucinations and SPDs in a pediatric population. Methods: We conducted a cross-sectional study with 335 children aged 6--18 years who visited the child psychiatry outpatient clinic at Osaka Metropolitan University Hospital between April 2020 and March 2023 and continued treatment for at least three months. After excluding those with intellectual disabilities or uncontrolled epilepsy, 304 participants were included in the analyses. The presence of hallucinations was assessed through interviews with the children and their parents. SPDs were evaluated using the Short Sensory Profile. Binomial logistic regression analysis was conducted to assess the association between hallucinations and SPDs, adjusting for age, sex, autism spectrum disorder, socioeconomic difficulties (low-income, single-parent households), and the presence of mood and anxiety disorders. Results: Hallucinations were present in 64 children (21%). Logistic regression analysis showed a significant positive association between SPDs and hallucinations, even after adjusting for age, sex, autism spectrum disorder, socioeconomic difficulties, and the presence of mood and anxiety disorders (odds ratio, 1.02; 95% CI, 1.008--1.036; p = 0.002). Conclusion: The results of this study suggest a potential association between hallucinations and SPDs in pediatric patients. Further prospective studies are needed to explore the causal relationship between these factors and determine whether interventions for SPDs can alleviate hallucinations in children.

Quetiapine is a second-generation atypical antipsychotic drug that has been commonly prescribed for the treatment of schizophrenia, major depressive disorder (depression), and other psychological disorders. Targeted inhibition of hyperpolarization-activated cyclic-nucleotide gated (HCN) channels, which generate Ih, may provide effective resistance against schizophrenia and depression. We investigated if HCN channels could contribute to the therapeutic effect of quetiapine, and its major active metabolite norquetiapine. Two-electrode voltage clamp recordings were used to assess the effects of quetiapine and its active metabolites 7-hydroxyquetiapine and norquetiapine on currents from HCN1 channels expressed in Xenopus laevis oocytes. Norquetiapine, but not quetiapine nor 7-hydroxyquetiapine, has an inhibitory effect on HCN1 channels. Norquetiapine selectively inhibited HCN1 currents by shifting the voltage-dependence of activation to more hyperpolarized potentials in a concentration-dependent manner with an IC50 of 13.9 ± 0.8 µM for HCN1 and slowing channel opening, without changing the kinetics of closing. Inhibition by norquetiapine primarily occurs from in the closed state. Norquetiapine inhibition is not sensitive to the external potassium concentration, and therefore, likely does not block the pore. Norquetiapine inhibition also does not dependent on the cyclic-nucleotide binding domain. Norquetiapine also inhibited HCN4 channels with reduced efficacy than HCN1 and had no effect on HCN2 channels. Therefore, HCN channels are key targets of norquetiapine, the primary active metabolite of quetiapine. These data help to explain the therapeutic mechanisms by which quetiapine aids in the treatment of anxiety, major depressive disorder, bipolar disorder, and schizophrenia, and may represent a novel structure for future drug design of HCN inhibitors.

Previous work suggests that interoception – the capacity to detect and interpret internal states of the body – may be disrupted in affective disorders. A related body of work suggests that reduced understanding of how interoceptive sensations relate to emotions (alexithymia) is also linked to these disorders. One route by which these deficits could maintain affective symptoms is poor emotion regulation – as perception and regulation of internal states share bidirectional links. However, depression and anxiety symptoms are highly co-morbid, and it remains unclear whether one or both are primarily affected. In this study, we sought to replicate prior results suggesting emotion dysregulation mediates the relationship between interoception/alexithymia and depressive symptoms, and to further determine whether co-morbid anxiety plays an additional, or alternative, explanatory role. Participants in two consecutive, non-clinical samples (Sample 1: N = 445, Mage=23.68; Sample 2: N = 196, Mage=24.99) completed measures of interoception (MAIA), alexithymia (TAS-20), emotion dysregulation (DERS), depression (BDI-II), and anxiety (STAI). Results in both samples confirmed that emotion dysregulation mediated the relationship between interoception and depressive symptoms and found a similar relationship with trait anxiety. When accounting for co-morbidity, anxiety – and not depression – appeared to best explain previous findings for interoception. In contrast, results suggested that depression – and not anxiety – explained prior links to alexithymia. These results may help guide interpretation of prior results when considering the high comorbidity in depression and anxiety symptoms and suggest unique treatment targets for each. Future research should examine these measures in clinical samples and with longitudinal data that can better disentangle the directional nature of these relationships. [ABSTRACT FROM AUTHOR]

Therapists are crucial in addressing the multifaceted challenges of fostering psychological well-being. The demanding nature of their profession emphasizes the need for ongoing professional development and support. Within the field of mental health interventions, there is increasing interest in investigating transformative approaches to chronic mood disorders. The objective of this study was to compare the efficacy of cognitive-behavioral therapy (CBT) and treatment based on allegorical schema modes in mitigating chronic mood disorders and difficulties in emotion regulation among therapists. Using a quasi-experimental design, psychotherapists from Tehran's 3rd district participated in pre-test and post-test assessments between December 2021 and December 2022. Fifteen therapists were included in each group through convenience sampling. Experimental Group 1 received 10 to 12 weekly face-to-face sessions based on allegorical schema modes, while Experimental Group 2 underwent cognitive-behavioral therapy sessions. Data collection included the Bromez Mood Questionnaire and the Difficulties in Emotion Regulation Scale (DERS). Analysis employed ANCOVA to compare outcomes between groups. The analysis revealed significant differences between research groups in chronic mood disorders and difficulty in emotion regulation, with F-values of 9.227 (p < 0.001) and 12.607 (p < 0.001), respectively. Post hoc tests showed significant differences in chronic mood disorders between the cognitive-behavioral group and both the allegorical schema modes group (MD = 4.583, p = 0.012) and the control group (MD = 7.333, p < 0.001). However, no significant difference was found between the allegorical schema modes group and the control group. Integrating cognitive-behavioral therapy and allegorical schema modes into therapists' ongoing support systems can aid in fostering adaptive coping strategies and promoting overall psychological health in the face of the demanding challenges inherent in the therapeutic profession.

Test anxiety is a problem affecting more and more adolescents and leading to significant negative consequences (Putwain & Daly, Educational Studies, 40(5), 554–570, 2014; von der Embse et al., Journal of Affective Disorders, 227, 483–493, 2018; von der Embse et al., School Psychology, 36(2), 86–96, 2021). However, few programs have been developed to target test anxiety in school settings among adolescents (Ergene, School Psychology International, 24(3), 313–328, 2003; von der Embse et al., Psychology in the Schools, 50(1), 57–71, 2013a). Thus, this study aims to evaluate the effectiveness of the Pastel intervention program in a randomized control trial, based on a cognitive-behavioral based approach combined with study skills to reduce test anxiety in adolescents. The pretest, posttest, and six-month follow-up effects of the program on test anxiety (primary outcome), as well as on secondary outcomes (social anxiety, generalized anxiety, depressive symptoms, and academic self-efficacy) were assessed. This study was carried out with 48 adolescents aged 14 to 17 years, from five private or public schools. The results indicated a medium effect on test anxiety between the pretest and posttest, and a low effect between the pretest and the six-month follow-up. The program also appeared to have an impact on some short-term and long-term secondary outcomes, such as social anxiety and depression symptoms. This study adds to the literature on test anxiety in adolescents by proposing an innovative and promising program to reduce symptoms associated with test anxiety and related issues.

Pregnancy in women living with human immunodeficiency virus (WLWH) represents an important challenge for maternal-fetal health. Besides, they can also present anxiety (Anx) and depression (Dep). Imbalances in serotonin (5-HT), dehydroepiandrosterone sulfate (DHEA-S), and cortisol (CORT) levels can contribute to Anx and Dep manifestations. Currently, there is not enough data about the neuroendocrine and neurochemical changes in pregnant WLWH with affective disorders. This study aimed to characterize 5-HT, DHEA-S, and CORT plasma levels in Mexican pregnant WLWH presenting Anx/Dep. Forty-two adult pregnant women were recruited during the third trimester of gestation at the National Institute of Perinatology in Mexico during 2019–2022. These patients were divided into three groups: (1) pregnant WLWH with Anx/Dep (n = 16), (2) pregnant without HIV but with Anx/Dep (n = 12), and (3) healthy pregnant women without Anx/Dep (n = 14). WLWH presented a marked reduction in 5-HT (41.33 ± 39.37 ng/dL) compared to non-infected pregnant women with Anx/Dep (220.2 ± 151.8 ng/dL) and the healthy group (370.0 ± 145.3 ng/dL). Anx/Dep infected and uninfected pregnant women showed a significant reduction in DHEA-S levels (86.58 ± 30.59 and 76.9 ± 36.7 µg/dL, respectively) compared to healthy subjects (149.7 ± 44.6 µg/dL). Anx and Dep symptoms were inversely correlated with 5-HT and DHEA-S levels. No significant differences were observed in CORT levels among the three groups (p = 0.094). Our results suggest the presence of a disbalance in 5-HT and DHEA-S levels in pregnant WLWH with affective symptoms. [ABSTRACT FROM AUTHOR]

Introduction: Current evidence suggests that early maladaptive schemas are affected in attention deficit hyperactivity disorder (ADHD). Most of the studies on the subject have been conducted with adults, but the number of studies conducted with adolescents with ADHD is quite limited. The aim of this study was to evaluate early maladaptive schemas in adolescents diagnosed with ADHD. Methods: The study included 66 patients diagnosed with ADHD and 70 healthy adolescents who were similar to the case group in terms of age and gender. Clinical evaluation of the case and control groups were performed with "The Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version, DSM-5 November 2016-Turkish Adaptation (K-SADS-PL-DSM-5-T)". "Conners-Wells Adolescent Self-Report Scale - Revised Short Form (CASS-RS)" and "Set of Early Maladaptive Schema Questionnaires for Children and Adolescents between the ages of 10-16" were administered to all participants. Results: It was determined that the schema scores of "dependence/incompetence", "vulnerability to harm or illness", "entitlement/grandiosity", "insufficient self-control", "subjugation" were significantly higher in the ADHD group than in the control group. A negative, significant relationship was found between age and "enmeshment/undeveloped self", "entitlement/grandiosity" and "insufficient self-control" schema scores. There was no significant difference between schema scores in terms of gender in the ADHD group. Additionally, no significant relationship was found between the education level of the parents, family income levels and schema scores. A significant positive relationship was found between the CASS-RS scores and all schema scores. As a result of the regression analysis, it was determined that CASS-RS scores positively predicted all schema scores, while the age variable negatively predicted only the schema scores of "enmeshment/undeveloped self". Discussion: Results of this study showed that there were significant differences in adolescents in the ADHD group compared to the control group in terms of early maladaptive schemas, and that ADHD symptom levels was associated with early maladaptive schemas.

Background: Alexithymia, a predictor in chronic illnesses, like cardiovascular and bipolar disorder (CD–BD), could be improved with a virtual reality (VR) cognitive remediation program. This secondary analysis of a previous randomized controlled trial (RCT) evaluates alexithymia improvement and its factors in an experimental group versus a control group, exploring extensions to individuals with comorbid non-psychiatric chronic conditions. Methods: A feasibility cross-over RCT (ClinicalTrials.gov NCT05070065) enrolled individuals aged 18–75 with mood disorders (BD, DSM-IV), excluding those with relapses, epilepsy, or severe eye conditions due to potential risks with VR. Alexithymia levels were measured using the Toronto Alexithymia Scale with 20 items (TAS-20). Results: The study included 39 individuals in the experimental group and 25 in the control group, with no significant age or sex differences observed. Significantly improved alexithymia scores were noted in the experimental group compared to controls (F = 111.9; p < 0.0001) and in subgroups with chronic non-psychiatric comorbidities (F = 4.293, p = 0.048). Scores were particularly improved for difficulty in identifying feelings (F = 92.42; p < 0.00001), communicating feelings (F = 61.34; p < 0.00001), and externally oriented thinking (F = 173.12; p < 0.00001). Conclusions: The findings highlight alexithymia enhancement in BD, even with comorbid non-psychiatric chronic diseases. Given its impact on BD progression and related conditions, like CD, developing and evaluating VR-based tools in this context is suggested by these findings. [ABSTRACT FROM AUTHOR]
