An increase in the prevalence of depressive symptoms can be seen in patients with severe somatic conditions, with a reduction in quality of life, an increase in sleep disturbances and an increased risk of suicide as some of the most serious consequences. However, few evidence-based interventions have been developed with the aim of reducing this comorbidity. The NEVERMIND system aims to address this issue by collecting psychometric and biomedical data via a smart shirt and a mobile app, which are used to predict patients’ depressive symptoms. Patients are then directed to personalised lifestyle behavioural advice, mindfulness-based therapy, and cognitive behavioural therapy.

The primary objective was to evaluate the effectiveness of the NEVERMIND system in reducing depressive symptoms in patients with somatic conditions compared to treatment as usual. Secondary objectives included the system’s effectiveness in preventing depressive symptoms, sustaining the effects at 24 weeks post-baseline, and reducing suicide ideation. Besides these, the usability, acceptability, and satisfaction of the system were examined in patients with breast or prostate cancer.

For this pragmatic randomised controlled trial, 425 patients diagnosed with myocardial infarction, breast or prostate cancer, kidney failure, or lower limb amputation were recruited from hospitals in Turin, Pisa and Lisbon. Data collection occurred at baseline, 12 weeks, and 24 weeks, with the primary outcome being depressive symptoms at week 12, measured by the Beck Depression Inventory II. Regarding the usability, acceptability and patient satisfaction, data from 288 patients was used.

The intervention group included 213 and the control group 212 patients, with the sample’s mean age being 59.41 (SD=10.70). Patients who used the system reported having statistically significant lower depressive symptoms at 12 weeks (mean difference=-3.05, p=0.004; 95%CI -5.12 to -0.99) compared to controls, with a clinically relevant effect size (Cohen’s d=0.41). Furthermore, significant reductions were found for suicide ideation (mean difference=-0.61, p=0.020; 95%CI -1.13 to -0.10) and incidence of depressive symptoms at week 12 (OR=0.43, p=0.019; 95%CI 0.22 to 0.87). The decrease in depressive symptoms was sustained at week 24 (mean difference=-1.34, p=0.015; 95%CI -2.41 to -0.26). The system was found to have good usability, with women rating the system more favourably than men and valuing its emotional support, while men used the system more frequently than women and valued the self-awareness that the system encouraged.

The NEVERMIND system was shown to be superior to standard care in reducing and preventing depressive symptoms among the studied sample. A new project will be launched in the near future to continue the examination of the system’s effectiveness.

Schizophrenia, as one of the most common disorders from the psychotic spectrum is most commonly detected in the phase of first psychosis and may pose a diagnostic challenge, as commonly comprise a heterogeneous group of schizophrenias, with distinct clinical presentations. If it detected in its prodromal phase without clearly developed psychotic symptoms, the diagnosis is even more unreliable, as the transition to full blown psychosis in the next two years happens in 15-40% of more, depending probably on a variety of cumulative environmental risk factors (including childhood trauma, the use of high-potency cannabis, urbanicity, season of birth). Moreover, the first episode psychosis may underlie for example the first manic episode, brief intermittent psychotic symptoms in persons with borderline personality disorders, acute reaction to trauma, the use of cannabis and psychostimulants and different organics causes, such as endocrinologic disorders and autoimmune encephalitis. Therefore, in everyday clinical practice, the diagnosis of first episode psychosis always requires an assessment of possible causes of psychosis, and also factors that may influence prognosis and treatment. Usual assessment include detailed anamnestic and heteroanamnestic data, physical examination, standard blood laboratory findings, drugs in urine/ blood, EEG and CT/MR scan. The absence of typical risk factors for schizophrenia, as well as the absence of premorbid symptoms and developmental course typical for schizophrenia, abrupt course of psychotic symptoms, symptoms such as disorientation, catatonia, speech disturbances, alteration of consciousness, neurologic signs, autonomic dysfunction and laboratory aberrations may be especially indicative for organic cause and possibly encephalitis and require further confirmation with the analysis of cerebrospinal liquor with antineuronal antibodies.

Hungarians exhibit more negative attitudes toward help-seeking for mental health problems compared to other European countries. However, research on help-seeking in Hungary is limited, and it is unclear how stigma relates to help-seeking when considering demographic and clinical characteristics. We used a network analytic approach to simulate a stigma model using hypothesized constructs in a sizable sample of Hungarian adults.

Participants were 345 adults recruited from nine primary care offices across Hungary. Participants completed self-report measures assessing public stigma, self-stigma, experiential avoidance (EA), attitudes toward seeking professional psychological help, anxiety, depression, demographics, prior use of mental health services, and whether they have a family member or friend with a mental health condition.

EA and anxiety were the most central nodes in the network. The network also revealed associations between greater EA with greater public stigma, anxiety, depression, and having a family member or friend with a mental health condition. More positive attitudes toward seeking help were associated with lower self-stigma, public stigma, and having received psychological treatment in their lifetime. Being female was associated with lower income, higher education, and having received psychological treatment in their lifetime. Finally, having a family member or friend with a mental health condition was associated with having received psychological treatment in their lifetime and greater public stigma.

The strength centrality and associations of EA with clinical covariates and public stigma implicate its importance in stigma models. Findings also suggest that while some aspects of existing stigma models are retained in countries like Hungary, other aspects may diverge.

The change in symptoms necessary to be clinically relevant in obsessive-compulsive disorder (OCD) is currently unknown. In this study, we aimed to create an empirically validated threshold for clinical significance or minimal important difference (MID).

We analyzed individual participant data from short-term, double-blind, placebo-controlled registration trials of selective serotonin reuptake inhibitors in adult OCD patients. Data were collected from baseline to week 12. We used equipercentile linking to equate changes in the Clinical Global Impression (CGI) scale to changes in the Yale-Brown Obsessive-Compulsive Scale (YBOCS). We defined the MID as the YBOCS change linked to a CGI improvement of 3 (defined as “minimal improvement”).

We included 7 trials with a total of 1216 patients. The CGI-scores and YBOCS were moderately to highly correlated. The MID corresponded to 4.9 YBOCS points (95% CI 4.4–5.4) for the full sample, or a 24% YBOCS-decrease compared to baseline. The MID varied with baseline severity, being lower in the group with mild symptoms and higher in the group with severe symptoms.

By linking the YBOCS to the CGI-I, this is the first study to propose an MID in OCD trials. Having a clearly defined MID can guide future clinical research and help interpretation of efficacy of existing interventions. Our results are clinician-based; however, there is further need for patient-reported outcomes as anchor to the YBOCS.

Childhood trauma is a severe form of stress that has been strongly related to both the appearance of a psychotic disorder and the existance of social cognition disturbances. We hereby hypothesize childhood trauma might be a transdiagnostic marker of social cognition disturbances across the psychosis spectrum, regardless of the main diagnosis.

To investigate the effect of different forms of childhood trauma in social cognition impairments in first-episode psychosis, at-risk mental states for psychosis and healthy controls.

Using cross-sectional data, we will examine the relationship between different kinds of chidlhood trauma (measured with the Childhood Trauma Questionnaire, CTQ) and several social cognition domains, including facial emotion recognition, theory of mind (assessed using the Movie Assessment for Social Cognition, MASC, The Hinting Task, and the Faux-Pas Questionnaire). Intra and inter-group differences be studied for three study groups, including patients with first-episode psychosis (n=60), subjects with at-risk mental states for psychosis (n=60), and healthy controls (n=60).

Abstract: This presentation seeks to explore the interplay between various types of psychological traumas and their potential correlation with the development of distinct types and severities of eating disorders. Emphasis will be placed on elucidating the underlying biological underpinnings and psychological and developmental factors that contribute to the manifestation of diverse eating disorder phenotypes in individuals who have experienced childhood maltreatment.

Drawing upon existing research and novel insights, I will present some data from studies investigating the notion that the observed variations in eating disorder presentations may be linked especially to environmental influences. Contrary to the conventional focus on genetic determinants, our findings suggest that the differential ecophenotypic expression of eating disorders may not solely be attributed to DNA variants but rather to the complex interplay between genetic predispositions and environmental contexts.

In particular, I will expose the concept of an ecophenotype characteristic of eating disorders associated with childhood maltreatment, positing that the unique ecological context in which an individual is raised significantly influences the trajectory and severity of their eating disorder. This exploration extends beyond a mere examination of genetic markers, shedding light on the environmental and ecosystemic factors that shape the development of an individual’s relationship with food and body image.

Traumatic exposure is a common global problem across nations. It is currently well established that childhood trauma is associated with increased risk for psychopathology transdiagnostically, with children having experienced trauma being twice as likely to develop a mental health condition compared to those who have never experienced trauma. According to population-based studies, this heightened risk for the emergence of mental health disorders persists throughout adolescence and adulthood. The risk for psychopathology seems to be most marked in children exposed to interpersonal violence (child emotional and physical abuse, neglect, sexual violence). In this presentation, we will summarize the results of an increasing number of published studies that have examined the mechanisms underlying vulnerability to psychopathology following childhood trauma and protective factors that buffer this risk. Specifically, we will highlight the role of emotion dysregulation and interpersonal difficulties, related to disrupted threat processing following trauma exposure, in mediating the impact of trauma on internalizing and externalizing symptoms. Research studies have also identified protective factors accross the lifespan that might mitigate these outcomes, including social support and emotional skills building. Based on this review, we will suggest a conceptual transdiagnostic and biopsychosocial model of risk and resilience, which can provide opportunities and targets for early interventions and treatment, at the primary and secondary healthcare levels, as well as the social, public health and community levels. Our model is based on a socioecological and multisystemic paradigm of risk and resilience, where resilience is conceptualized as an interaction between individuals and resourceful environments and communities.

Obesity-related cardiometabolic comorbidity is common in major depressive disorder (MDD). However, sex differences and MDD recurrence may modify the MDD-obesity-link.

Sex-specific associations of MDD recurrence (single [MDDS] or recurrent episodes [MDDR]) and obesity-related traits were analyzed in 4.100 adults (51.6% women) from a cross-sectional population-based cohort in Germany (SHIP-Trend-0). DSM-IV-based lifetime MDD diagnoses and MDD recurrence status were obtained through diagnostic interviews. Obesity-related outcomes included anthropometrics (weight, body mass index, waist- and hip-circumference, waist-to-hip ratio, waist-to-height ratio), bioelectrical impedance analysis of body fat mass and fat-free mass, and subcutaneous (SAT) and visceral adipose tissue (VAT) from abdominal magnetic resonance imaging. Sex-stratified linear regression models predicting obesity-related traits from MDD recurrence status were adjusted for age, education, and current depressive symptoms.

790 participants (19.3%) fulfilled lifetime MDD criteria (23.8% women vs. 14.5% men, p<0.001). In women, MDDS was inversely associated with anthropometric indicators of general and central obesity, while MDDR was positively associated with all obesity-related traits, except waist-to-hip ratio and fat-free mass. In women, MDDR versus MDDS was associated with higher levels of obesity across all outcomes except fat-free mass. In men, MDD was positively associated with SAT regardless of MDD recurrence. Additionally, lifetime MDD was positively associated with VAT in men. Results remained significant in sensitivity analyses after exclusion of participants with current use of antidepressants.

The MDD-obesity association is modified by MDD recurrence and sex independent of current depressive symptoms. Accounting for sex and MDD recurrence may identify individuals with MDD at increased cardiometabolic risk.

Increased psychosis risk has long been reported for some migrant and ethnic minority populations, a finding has been replicated in different parts of the world, with risk seeming to persist for further generations. Several explanations such as genetic liability or selective migration, higher cannabis-use or higher exposure to neurodevelopmental risk factors were considered unlikely explanations. Rather, exposure to adversity experiences found to be a determinant of psychotic disorders, such as parental separation, social and economic disadvantage, discrimination, social exclusion and marginalization. Additionally, migrants often live in cities, where high population density, low social cohesion and social fragmentation and deprivation, combined with lack of green space and urban stress increase the psychosis risk. Although previous research work has emphasized the quantitative exploration of social-environmental determinants of psychosis, qualitative studies allow for the generation of innovative, rich and nuanced understandings about a given phenomenon, being an ideal approach in face of complex social dynamics and contexts. Concretely, the associations are established, however, the underlying mechanisms and experiences remain largely unknown.

This study aims to address several research gaps identified in research on the issues of psychosis, socio-environmental determinants of mental health, migration and ethnicity, and inequalities by exploring the life narratives and experiences of service-users with first psychosis with distinct ethnic, racial and migrant backgrounds.

Participants aged between 18 and 35 years old, who have been diagnosed with a first psychosis are recruited in Montreal, Canada, and in the Netherlands. The aim is to recruit at least 20-25 individuals from each site, but recruitment is still ongoing. Qualitative interviews of about an hour are being held, and transcripts will be analyzed with Nvivo, software for qualitative data. Categories and clusters will be formed from the narratives, resulting in common themes that are important to the patients, in their understanding of the development of their psychosis, and the help they have received.

Preliminary data show that the patients have predominantly African or (Eastern)European background, moved around a lot, and experiences inequities. Help and care were not always available for them, not always beneficial. Participants experiences a lot of isolation and deplacement, together with socio-economic disadvantages. Common themes as to by which mechanisms these aspects play a role will further be explored.

These findings will be discussed in light of the quantitative data already existing. Implications for prevention and interventions will be discussed.

High rates of psychiatric comorbidities have been found in people with problem gambling (PBG), including substance use, anxiety, and mood disorders. Psychotic disorders have received less attention, although this comorbidity is expected to have a significant impact on the course, consequences, and treatment of PBG. This review aimed to estimate the prevalence of psychotic disorders in PBG.

Medline (Ovid), EMBASE, PsycINFO (Ovid), CINAHL, CENTRAL, Web of Science, and ProQuest were searched on November 1, 2023, without language restrictions. Studies involving people with PBG and reporting the prevalence of schizophrenia spectrum and other psychotic disorders were included. Risk of bias was assessed using the Joanna Briggs Institute critical appraisal checklist for systematic reviews of prevalence data. The pooled prevalence of psychotic disorders was calculated using a random effects generalized linear mixed model and presented with forest plots.

Of 1,271 records screened, 22 studies (n = 19,131) were included. The overall prevalence of psychotic disorders was 4.9% (95% CI, 3.6–6.5%, I2 = 88%). A lower prevalence was found in surveyed/recruited populations, compared with treatment-seeking individuals and register-based studies. No differences were found for factors such as treatment setting (inpatient/outpatient), diagnoses of psychotic disorders (schizophrenia only/other psychotic disorders), and assessment time frame (current/lifetime). The majority of included studies had a moderate risk of bias.

These findings highlight the relevance of screening problem gamblers for schizophrenia spectrum and other psychotic disorders, as well as any other comorbid mental health conditions, given the significant impact such comorbidities can have on the recovery process.

According to the latest Intergovernmental Panel on Climate Change (IPCC) Report (2022), climate changes (e.g. rising sea levels and temperatures and) are noticeable and intensifying on the entire planet. Extreme weather events or ecological disasters are occurring with increased frequency and intensity. Anthropogenic climate change has been called “the defining issue of our time” (United Nations, 2022) and “the greatest threat to global health in the 21st century” (World Health Organization, 2015). Health impacts from climate change may include increased morbidity and mortality from worsening cardiopulmonary health, and greater risk of infectious diseases and mental illness. During this lecture, we will discuss environmental aspects that clearly have a negative impact on the mental well-being of the general population and, more specifically, the psychiatric population. The focus will primarily delve deeper into climate anxiety.

Science, Ethics, Solidarity… These three words are mottos of Psychiatric Association of Türkiye (PAT), since its foundation in 1995. In accordance, PAT has Code of Ethics for more than 20 years. There are many developments and changes both in practicing psychiatry and in the community in the last couple of decades. As a result, many new ethical questions, dilemmas and approaches arise for psychiatry. PAT had decided to update the Code of Ethics about two years ago and the updating process is almost on the edge of finalization.

In this presentation, main points of the updated and newly written principles will be summarized with special references to recent developments in the world and updated or newly written international Code of Ethics such as, EPA, WPA, and several national associations’ documents.

One of the most important outcome and benefit of such an updating process is modelling the project on a participatory base, having wide feedback and inputs from experts (as many as possible, enriched by diverse interests of related disciplines) and reaching as many colleagues as possible from different working conditions. A six step project with this perspective was prepared and implemented, and will be summarized in the presentation for international exchange of experiences.

Cardiometabolic diseases (CMDs) including heart disease, stroke, and type 2 diabetes have been individually linked to depression. However, their combined impact on depression risk is unclear. We aimed to examine the association between cardiometabolic multimorbidity and depression and explore the role of genetic background in this association.

Within the Swedish Twin Registry, 40,080 depression-free individuals (mean age 60 years) were followed for 18 years. Cardiometabolic multimorbidity was defined as having ≥2 CMDs. CMDs and depression were ascertained based on the National Patient Register. Cox regression was used to estimate the CMD-depression association in a classical cohort study design and a matched co-twin design involving 176 twin pairs. By comparing the associations between monozygotic and dizygotic co-twins, the contribution of genetic background was estimated.

At baseline, 4809 (12.0%) participants had one CMD and 969 (2.4%) had ≥2 CMDs. Over the follow-up period, 1361 participants developed depression. In the classical cohort design, the multi-adjusted hazard ratios (95% confidence interval [CIs]) of depression were 1.52 (1.31–1.76) for those with one CMD and 1.83 (1.29–2.58) for those with ≥2 CMDs. CMDs had a greater risk effect on depression if they developed in mid-life (<60 years) as opposed to late life (≥60 years). In matched co-twin analysis, the CMD-depression association was significant among dizygotic twins (HR = 1.63, 95% CI, 1.02–2.59) but not monozygotic twins (HR = 0.90, 95% CI, 0.32–2.51).

Cardiometabolic multimorbidity is associated with an elevated risk of depression. Genetic factors may contribute to the association between CMDs and depression.

We need to better understand the risk factors and predictors of medication-related weight gain to improve metabolic health of individuals with schizophrenia. This study explores how trajectories of antipsychotic medication (AP) use impact body weight early in the course of schizophrenia.

We recruited 92 participants with first-episode psychosis (FEP, n = 92) during their first psychiatric hospitalization. We prospectively collected weight, body mass index (BMI), metabolic markers, and exact daily medication exposure during 6-week hospitalization. We quantified the trajectory of AP medication changes and AP polypharmacy using a novel approach based on meta-analytical ranking of medications and tested it as a predictor of weight gain together with traditional risk factors.

Most people started treatment with risperidone (n = 57), followed by olanzapine (n = 29). Then, 48% of individuals remained on their first prescribed medication, while 33% of people remained on monotherapy. Almost half of the individuals (39/92) experienced escalation of medications, mostly switch to AP polypharmacy (90%). Only baseline BMI was a predictor of BMI change. Individuals in the top tercile of weight gain, compared to those in the bottom tercile, showed lower follow-up symptoms, a trend for longer prehospitalization antipsychotic treatment, and greater exposure to metabolically problematic medications.

Early in the course of illness, during inpatient treatment, baseline BMI is the strongest and earliest predictor of weight gain on APs and is a better predictor than type of medication, polypharmacy, or medication switches. Baseline BMI predicted weight change over a period of weeks, when other traditional predictors demonstrated a much smaller effect.

Borderline personality disorder (BPD) is associated with excess suicide risk, natural-cause mortality, comorbid medical conditions, poor health habits and stress related epigenomic alterations. This presentation will report findings of BDNF and stress system associated epigenetic alterations in a group of severely impaired BPD and suicidal patients. Further, findings of GrimAge – a state-of-the-art epigenetic age (EA) estimator- in patients with BPD and attempted suicide patients will be presented. Genome-wide methylation patterns were measured using the Illumina Infinum Methylation Epic BeadChip in whole blood from well characterized 97 BPD patients, 88 suicide attempters and 32 healthy controls.

Despite major advances in research into the neurobiological basis of mental illness, there have been hardly any new developments in new drug therapies. As there are approximately 30% of affected individuals that do not respond sufficiently to available treatments, there is a significant unmet medical need for new therapeutic approaches. About 90% of novel substances that have shown promise in animal studies are not effective in clinical trials. Recent research on human induced pluripotent stem cells (hiPSC) could lead to the use of more human-tailored models in this field. IPSC-derived cell models and organoids may be very attractive for preclinical screening and bridge the gap between in vitro and in vivo studies, reducing animal testing. However, the next steps must first demonstrate the validity and reproducibility of the initial functional results from the hIPSC models of mental illness. In our own studies on neuronal cell models of patients with attention-deficit/hyperactivity disorder (ADHD) with rare PARK2 gene variants, we were able to show evidence of mitochondrial dysfunction and impaired energy metabolism. Additionally, we have first hints at a oxidative dysbalance which could be as well targeted by medication. In a model of cortical development of ADHD patients with common variants in the ADGRL3 gene, we found first evidence for altered neuronal maturation as well as abnormalities in calcium metabolism and glutamatergic functionality compared to cells from healthy controls. In summary, these first results are promising that hIPSC models can contribute new insights into cellular pathomechanisms of mental and neurodevelopmental disorders and the development of new, individualised therapeutic approaches.

Cognitive impairment (CI) is one of the most prevalent and burdensome consequences of COVID-19 infection, which can persist up to months or even years after remission of the infection. Current guidelines on post-COVID CI are based on available knowledge on treatments used for improving CI in other conditions. The current review aims to provide an updated overview of the existing evidence on the efficacy of treatments for post-COVID CI.

A systematic literature search was conducted for studies published up to December 2023 using three databases (PubMed–Scopus–ProQuest). Controlled and noncontrolled trials, cohort studies, case series, and reports testing interventions on subjects with CI following COVID-19 infection were included.

After screening 7790 articles, 29 studies were included. Multidisciplinary approaches, particularly those combining cognitive remediation interventions, physical exercise, and dietary and sleep support, may improve CI and address the different needs of individuals with post-COVID-19 condition. Cognitive remediation interventions can provide a safe, cost-effective option and may be tailored to deficits in specific cognitive domains. Noninvasive brain stimulation techniques and hyperbaric oxygen therapy showed mixed and preliminary results. Evidence for other interventions, including pharmacological ones, remains sparse. Challenges in interpreting existing evidence include heterogeneity in study designs, assessment tools, and recruitment criteria; lack of long-term follow-up; and under-characterization of samples in relation to confounding factors.

Further research, grounded on shared definitions of the post-COVID condition and on the accurate assessment of COVID-related CI, in well-defined study samples and with longer follow-ups, is crucial to address this significant unmet need.
