IntroductionChronic inflammation in depression is associated with decreased levels of neurotrpohic factors and suppressed neurogenesis. We have previously shown that intranasal therapy with soluble factors from M2 macrophages polarized by interaction with apoptotic cells in serum deprivation conditions (M2(LS); LS - low serum) and characterized by anti-inflammatory and pro-regenerative activity leads to the correction of the behavioral pattern in mice with a depression-like state.ObjectivesThe present study focuses on the effect of M2(LS) macrophages on neuronal density in the frontal cortex and hippocampus of depression-like
mice.MethodsDepressive-like state was formed in passive male mice (CBAxC57Bl/6)F1) as a result of repeated experience of defeat in agonistic interactions with aggressive partner during 20 days (the sensory contact model). Depression-like mice were then treated intranasally with M2(LS) macrophages conditioned medium for 7 days. After that, the number of mature neurons in the frontal cortex and hippocampus was assessed using Nissl staining.ResultsThe neuronal density in the pyramidal layer of the frontal cortex was significantly lower in depression-like mice than that in the intact control group of mice (p=0,047). At the same time, the number of neurons in the experimental group of mice that received soluble M2(LS) factors, was higher than that in depressive-like untreated control mice (p=0,003) and was comparable to that in the intact group of mice. At the same time the neuronal density in the CA1 and CA3 hippocampal areas did not change in depression-like mice following intranasal treatment with conditioned medium of M2(LS) macrophages.ConclusionsThe data obtained may indicate the neuroprotective effect of M2(LS) macrophages in the stress-induced depression model, which is realized through soluble factors and manifests itself in an increase of the pyramidal neurons density in the frontal cortex.Disclosure of InterestNone Declared
Attention flexibility is associated with retinal cup-to-disk ratio in patients with schizophrenia spectrum disorders
Authors: Jerotic S. , Maric N. 
Published: August 2024

IntroductionIn recent years, there has been increasing interest in the potential use of retinal imaging as a non-invasive and easily accessible tool for investigating the neurobiological underpinnings of schizophrenia. Studies have suggested that patients with schizophrenia spectrum disorders (SSD) have structural abnormalities in the retina, including changes in retinal thickness and the ratio of the retinal cup-to-disk ratio.ObjectivesTo investigate the relationship between retinal cup-to-disk ratio and cognitive performance in patients with SSD using a high-definition retinal imaging device – optical coherence tomography (OCT) scanner.MethodsThe sample was comprised of twenty patients with SSD (F20-F29 according to ICD-10 criteria). All diagnoses were confirmed by a researcher using the Mini International Psychiatric Interview. All patients underwent complete ophthalmological examination, excluding any ocular pathology. Retinal thickness was measured in both eyes of all patients with a high-definition spectral-domain OCT device. Examined retinal parameters were: total retinal nerve fiber layer thickness (RNFL); RNFL thickness in all eye quadrants (nasal, temporal, superior, inferior); RNFL symmetry; average macular volume (MV); average macular thickness (MT); ganglion cell layer thickness (GC); average retinal cup-to-disk (C/D) ratio, vertical C/D ratio. Cognitive performance of all patients was tested using the Intra/Extradimensional Set Shift Task (IED). IED is a component of a state-of-the-art computerized battery for cognitive assessment – Cambridge Neuropsychological Automated Test Battery. IED is a measure of maintenance, shifting and flexibility of attention. Associations between retinal variables and IED measures were determined with Pearson correlation analyses.ResultsMean age of patients was 33 ± 7.5 years. Fifty five percent of the sample was male, illness duration was 6.2 ± 3.9 years. Daily dosage of chlorpromazine was 225.7 ± 108.8 mg. Retinal C/D ratio in the right eye was positively associated with IED total errors (r=0.50; p=0.02) and negatively with IED stage progression (r=-0.52, p=0.18). Likewise, vertical C/D ratio was positively associated with IED total errors (r=0.49; p=0.02) and negatively with IED stage progression (r=-0.52, p=0.18).ConclusionsPrevious analyses of retinal parameters in patients with schizophrenia point towards enlargement of retinal cup-to-disk ratio, irrespective of any underlying somatic comorbidities. Our data shows worsening of attention flexibility in association with the increase of cup-to-disk ratio in patients with schizophrenia spectrum disorders. The significance of cup-to-disk retinal disturbance in schizophrenia spectrum disorders and its connection with cognitive performance should be further evaluated and supplemented with measurements of functional adaptation in these patients.Disclosure of InterestNone Declared

Authors: Leal I. , Izquierdo A. , Cabello M. 
Published: August 2024

IntroductionNeighborhood socioeconomic status seems to be related to functioning in patients with first episode of psychosis(FEP).ObjectivesThe present study aimed to assess if neighborhood vulnerability and risk of social exclusion could predict functional outcomes in people with FEP after controlling for other key variables identified in previous literature.MethodsA total of 137 patients with FEP (DSM-IV-TR criteria) and 90 controls comprised the study sample from February 2013 to May 2019. Functioning was assessed with the WHO Disability Assessment Schedule. Neighborhood vulnerability was measured using a multidimensional socioeconomic deprivation index; data for the index were collected by the Madrid City Council and based on the participant’s home address. Multilevel mixed-effects regression analyses were conducted to estimate the effects of neighborhood vulnerability on functioning.ResultsOur results show that FEP patients could be more vulnerable to the effects of neighborhood-level characteristics than healthy controls (B = 1,570.173; z = 3.91; Pc .001). In addition, our findings suggest that higher neighborhood vulnerability is related to greater functional disability in people with FEP, after controlling for other relevant confounders (B = 1,230.332; 2=2.59; P=.010). based on the participant’s home address. Multilevel mixed-effects regression analyses were conducted to estimate the effects of neighborhood vulnerability on functioning.ResultsOur results show that FEP patients could be more vulnerable to the effects of neighborhood-level characteristics than healthy controls (B = 1,570.173; z = 3.91; Pc 001). In addition, our findings suggest that higher neighborhood vulnerability is related to greater functional disability in people with FEP, after controlling for other relevant confounders (B = 1,280.332; z=2.59; P= 010).ConclusionsThese results highlight the importance of incorporating contextual factors into assessment of patients with FEP, since psychosocial difficulties observed In these patients could be partially related to the quality of neighborhood social-related resources.Disclosure of InterestNone Declared
Relationship of Interoceptive Accuracy with Craving, Personality Dimensions, and Alexithymia in Alcohol Use Disorder
Authors: Kahyacı Kılıç E. , Sönmez M. B. 
Published: August 2024

IntroductionInteroception encompasses processes that involve receiving, processing, and integrating bodily signals with external stimuli, ultimately influencing ongoing motivated behaviors. Disruptions in these interoceptive processes are believed to contribute to the development and progression of alcohol use disorder (AUD). Interoceptive accuracy (IAc), the objective dimension of interoception, has been shown to be decreased in patients with AUD. Traits linked to substance use vulnerability, such as personality dimensions and alexithymia, may be associated with decreased IAc.ObjectivesOur objective was to compare the heartbeat perception (HBP) scores, as a measure of IAc, between abstinent inpatients with AUD and healthy controls. Additionally, we aimed to investigate potential associations between IAc and variables such as alcohol craving, personality dimensions, and alexithymia.MethodsThe study comprised 48 abstinent inpatients with AUD and 68 healthy control subjects. All participants completed a heart rate tracking task, serving as an objective physiological measure of IAc. In addition to the IAc task, several assessments were administered to the patient group, including the Alcohol Use Disorders Identification Test (AUDIT), the Penn Alcohol Craving Scale (PACS), the Temperament and Character Inventory (TCI), and the Toronto Alexithymia Scale (TAS-20). Patients were recruited for a 28-day abstinence-based inpatient treatment program, and all assessments were conducted during the final week of hospitalization at the Alcohol and Substance Addiction Treatment Center in Trakya University School of Medicine (Edirne, Türkiye).ResultsPatients’ HBP scores (mean ± standard deviation: 0.59±0.21) were significantly lower than those of healthy control subjects (0.74±0.15) (t=-4.469, p<0.001). The patients’ HBP scores showed significant negative correlations with AUDIT (r=-0.312, p=0.035), PACS (r=-0.361, p=0.019), and TAS-20 scores (r=-0.406, p=0.004). Additionally, there was a significant positive correlation between patients’ HBP scores and TCI self-directedness scores (r=0.371, p=0.009), and a near-significant correlation with TCI persistence scores (r=0.282, p=0.052). TCI novelty seeking, harm avoidance, reward dependence, cooperativeness, and self-transcendence scores did not significantly correlate with patients’ HBP scores (p>0.05).ConclusionsOur findings may support the hypothesis that interoceptive processes play a role in AUD, and that certain traits linked to vulnerability to alcohol use are associated with decreased IAc.Disclosure of InterestNone Declared
The uncharted territory of female adult ADHD: a comprehensive review
Authors: Oroian B. A. , Costandache G. , Popescu E. , Nechita P. , Szalontay A. 
Published: August 2024

IntroductionAttention-Deficit/Hyperactivity Disorder (ADHD), once considered a predominantly childhood condition, has increasingly gained recognition as a prevalent and clinically significant concern among adult women. They often display a distinctive symptom profile characterized by high levels of inattention, emotional dysregulation, and difficulties in executive functioning. Diagnosis of female adult ADHD is frequently complicated by gender bias in traditional diagnostic criteria, which may fail to account for the unique ways in which women manifest the disorder.ObjectivesThis comprehensive literature review aims to characterize the unique symptomatology of female adult ADHD, including variations in inattention, hyperactivity, and impulsivity, as well as the presence of emotional dysregulation. It also seeks to explore the diagnostic challenges stemming from gender bias in diagnostic criteria and the role of comorbidity in diagnostic complexity. Additionally, the review assesses the broad spectrum of functional impairments experienced by adult women with ADHD, spanning academic, occupational, interpersonal, and emotional domains.MethodsThis literature review comprises a systematic examination of published research articles, clinical studies, and relevant academic literature addressing female adult ADHD. A comprehensive search strategy involving electronic databases, including PubMed, PsycINFO, and Google Scholar, was employed to identify peer-reviewed articles published between 2000 and 2023. The selected studies underwent critical appraisal for quality and relevance to the review’s objectives.ResultsThe synthesis of existing literature reveals that female adult ADHD presents a distinctive clinical picture characterized by a higher prevalence of inattention, emotional dysregulation, and comorbid conditions such as mood and anxiety disorders. Diagnostic challenges arise from gender bias in diagnostic criteria and the absence of overt hyperactivity, often leading to delayed diagnosis or misdiagnosis. Functional impairments extend to academic, occupational, interpersonal, and emotional domains, affecting the overall quality of life for affected individuals. Gender-specific factors, including societal expectations and biases in healthcare evaluation, contribute to diagnostic disparities and hinder timely access to appropriate interventions.ConclusionsThe literature review underscores the critical need for enhanced recognition, understanding, and tailored support for female adults with ADHD. The distinct symptomatology, diagnostic complexities, functional impairments, and gender-specific factors contribute to a multifaceted clinical landscape. Advancing gender-sensitive diagnostic criteria, increasing awareness among healthcare professionals, and developing interventions that address the unique needs of this population are essential steps toward improving the quality of life and outcomes for female adults with ADHD.Disclosure of InterestNone Declared

IntroductionThe comorbidity between depression and anxiety is a common occurrence. The DSM-5 introduced the “anxious distress” (AD) specifier that can be applied to any depressive episode – both in major depressive disorder (MDD) and bipolar disorder (BD) – when symptoms such as feelings of tension, restlessness, difficulty concentrating, and fear that something awful may happen or to lose control are present. Longitudinal data showed that the AD specifier may be an effective predictor of chronicity, time to remission, and functional disability in depressive disorders. In addition, evidence on AD proved its association with increased depressive symptom severity.ObjectivesAvailable literature seems to suggest that AD occurs in a specific subgroup of patients, thus enabling a peculiar clinical profile to be outlined. To expand knowledge in this field, we performed a cross-sectional study aimed at identifying clinical correlates of AD in people with major depressive episodes.MethodsAdult people admitted to two psychiatric inpatient units in the northern area of the Metropolitan City of Milan from May 2020 to December 2022 were screened for a major depressive episode and relevant specifiers using the Structured Clinical Interview for DSM-5 (SCID-5). Data on socio-demographic and clinical variables were collected. The severity of depressive and manic symptoms was assessed using the Montgomery–Åsberg Depression Rating Scale (MADRS) and Young Mania Rating Scale (YMRS), respectively. Univariate comparisons between participants with and without AD were conducted, and two multiple logistic regression models were arranged to investigate the association between AD and candidate explanatory variables.ResultsWe included 206 inpatients with a major depressive episode (mean age =48.4 ± 18.6 years; males = 38.8%), of whom 155 diagnosed with MDD and 51 with BD. AD was present in 137 participants (66.5%). Mixed features (p=0.049), higher YMRS scores (p=0.004), psychotic features (p<0.05), and a diagnosis of MDD (p<0.05) were found to be associated with AD in the multiple logistic regression analysis.ConclusionsNotwithstanding some limitations, such as the cross-sectional design and the inclusion of inpatient only, our study highlights the association of AD with mixed and psychotic features, as well as with MDD. Clinical implications of these results include the possible contribution in delineating a specific symptom profile in people with AD during a major depressive episode.Disclosure of InterestNone Declared
Comorbidity costs for the healthcare of mental patients
Authors: Dr. Fadgyas-Freyler P. 
Published: August 2024

IntroductionMost patients with mental disorders exhibit multiple comorbidities. Without doubt the presence of multiple co-occurring somatic and mental disorders is associated with a higher insurance spending for the psychiatric patients. The details of this association need to be elucidated.ObjectivesThe aim of current study was 1) to delineate the typical nonmental comorbidities that occur among mental patients, and 2) to investigate social health insurance spending on comorbidities compared to the direct mental care costs of the same population. The analysis offers unique insight into the health care spending, since it focuses not only the costs of psychiatric care but reflects the whole range of treatments delivered to this group.MethodsA database with the claim records of the Hungarian NHIF was created including direct healthcare costs for mental diagnosis. Patients were recorded either in primary or in specialist care with at least one mental health diagnosis in the last pre-pandemic year (2019). Adopting a case-control design, spending and comorbidities were compared to the control group, which comprised patients who did not have any mental diagnosis. Cases and controls were matched on demographic characteristics like age, gender, place of residence with deprivation index and marital status..ResultsMental problems affected in 2019 more than 1,5 million persons in Hungary. Half of them did not access specialist care but were only seen with the mental diagnosis by a GP. Direct insurance spending for mental care is around 156 million EUR/year with 4% of the total direct health spending. Besides these costs another 665 million EUR (+17% of all health spending) were reimbursed for the same patient group for the treatment of other diseases. With regards to affected patient numbers, the three most important comorbidities were cardio-vascular conditions (34% of mental patients with 14% of all spending of the group); diseases of the digestive system (29% vs 14%); and musco-sceletal conditions (28% / 9% ) In terms of spending three other disease groups also have to be considered as of high significance: carcinomas (4% patients vs 13% of spending); neurological disorders (13% /vs 7%); and diseases of the endocrine, nutritional and metabolic system (24% vs 6%).ConclusionsThe analysis aims to raise awareness for the complex issues of comorbidities of mental patients. We see that this patient group suffers heavily from other conditions the costs of which is much higher than the direct mental care costs. A better understanding of the coexistence of somatic and mental disorders and a holistic approach of treatment (care integration, reimbursement across different types of care, etc.) would be desirable.Disclosure of InterestNone Declared
Drug repurposing as add-on treatment strategy for mania and bipolar depression: systematic synthesis and qualitative appraisal of the existing meta-analytic evidence
Authors: Cavaleri D. , Bartoli F. , Crocamo C. , Carrà G. 
Published: August 2024

IntroductionIn the complex pathophysiology of bipolar disorder (BD), increasing evidence supports the involvement of neurobiological abnormalities beyond the classical ones, suggesting them as potential alternative therapeutic targets. Several drugs approved for different indications have thus been repurposed for the treatment of BD, all of them supported by a plausible biological rationale. Some recent reviews have provided an update on these possible additional treatment options for mania and bipolar depression, but no systematic synthesis and qualitative evaluation of meta-analytic findings has been made.ObjectivesTo provide a guidance on the available evidence on these treatments and their potential role in clinical practice, we conducted an umbrella review of meta-analyses of randomized placebo-controlled trials investigating drugs repurposed as add-on treatments for mania and bipolar depression.MethodsWe performed a systematic search and screening of the existing literature looking for the most up-to-date or comprehensive meta-analyses of randomized controlled trials (RCTs) on adults suffering from BD during an acute mood episode (mania or depression) which compared a repurposed drug and placebo as adjunctive treatments. We performed a critical appraisal according to “A MeaSurement Tool to Assess systematic Reviews” Version 2 (AMSTAR 2). We synthesized meta-analytic findings regarding efficacy, tolerability, and safety, also assessing the quality of evidence using the “Grading of Recommendations, Assessment, Development and Evaluations” (GRADE) approach.ResultsIn nine eligible meta-analyses investigating 12 drugs (four for mania and eight for bipolar depression) we observed a heterogeneous quality of reporting was according to AMSTAR 2.In mania, allopurinol (for symptoms reduction and remission at 4-8 weeks) and tamoxifen (for response and symptoms reduction at 4-6 weeks) showed higher efficacy than placebo, with evidence of low and very low quality, respectively.In bipolar depression, modafinil/armodafinil (for response, remission, and symptoms reduction at 6-8 weeks) and pramipexole (for response and symptoms reductionat 6 weeks) were superior to placebo, with low-quality evidence. Results on celecoxib and N-acetylcysteine were of low quality and limited to certain outcomes.ConclusionsOverall, the lack of evidence of high and moderate quality does not allow firm conclusions on the clinical utility of repurposed drugs as adjunctive treatments for mania and bipolar depression, limiting recommendations for their use in clinical practice. However, since some lines of evidence seem to hold some potential, and standard treatments for mania and bipolar depression remain not entirely satisfactory, the search for novel therapeutic targets and strategies for the management of BD warrants further research in the field.Disclosure of InterestNone Declared

Published: August 2024

AbstractBackground
Studies in different countries of defendants with mild to borderline intellectual disability found they have distinct characteristics from other defendants. The aim of this study was to examine several characteristics among defendants with intellectual disability comparing to those defendants without intellectual disability presenting to court services in London, England.Method
This was a retrospective data analysis of routine administrative data collected by the Liaison and Diversion services across five Magistrates courts in London, England. Data were analysed on defendants identified through screening to have an intellectual disability and compared to defendants without an intellectual disability.Results
9088 defendants were identified and of these 349 (4%) had an intellectual disability. Defendants with intellectual disability were over four times more likely to have comorbid attention deficit hyperactive disorder and over 14 times more likely to have autism spectrum disorder. There was an increased odds ratio of self-reported suicidal/self-harming behaviour for those defendants with intellectual disability compared to those without intellectual disability.ConclusionThis study has highlighted the increased vulnerability of defendants with intellectual disability for other neurodevelopmental disorders.Disclosure of Interest
