Yayın The effect of SARS-CoV-2 virus on resting-state functional connectivity during adolescence: Investigating brain correlates of psychotic-like experiences and SARS-CoV-2 related inflammation response(Elsevier Ireland Ltd, 2023-12) Yılmaz Kafalı, Helin; Daşgın, Hacer; Şahin Çevik, Didenur; Sozan, Sara Sinem; Oğuz, Kader K.; Mutlu, Müge; Özkaya Parlakay, Aslınur; Toulopoulou, TimotheaWe first aimed to investigate resting-state functional connectivity (rs-FC) differences between adolescents exposed to SARS-CoV-2 and healthy controls. Secondly, the moderator effect of PLEs on group differences in rs-FC was examined. Thirdly, brain correlates of inflammation response during acute SARS-CoV-2 infection were investigated. Eighty-two participants aged between 14 and 24 years (SARS-CoV-2 (n = 35), controls (n = 47)) were examined using rs-fMRI. Seed-based rs-FC analysis was performed. The positive subscale of Community Assessment of Psychotic Experiences-42 (CAPE-Pos) was used to measure PLEs. The SARS-CoV-2 group had a lesser rs-FC within sensorimotor network (SMN), central executive network (CEN) and language network (LN), but an increased rs-FC within visual network (VN) compared to controls. No significant differences were detected between the groups regarding CAPE-Pos-score. However, including CAPE-Pos as a covariate, we found increased rs-FC within CEN and SN in SARS-CoV-2 compared to controls. Among the SARS-CoV-2 group, neutrophil/lymphocyte and thrombocyte*neutrophil/lymphocyte ratio was correlated with decreased/increased FC within DMN and SN, and increased FC within CEN. Our results showed rs-FC alterations within the SMN, CEN, LN, and VN among adolescents exposed to SARS-CoV-2. Moreover, changes in rs-FC associated with PLEs existed in these adolescents despite the absence of clinical changes. Furthermore, inflammation response was correlated with alterations in FC within the triple network system.Yayın Attitudes of psychiatrists towards people with mental illness: a cross-sectional, multicentre study of stigma in 32 European countries(Elsevier Ltd, 2023-12) Őri, Dorottya; Szocsics, Péter; Molnár, Tamás; Bankovska Motlova, Lucie; Kazakova, Olga; Mörkl, Sabrina; Wallies, Michael; Abdulhakim, Mohamed; Boivin, Sylvie; Bruna, Krista; Cabaços, Carolina; Carbone, Elvira Anna; Dashi, Elona; Grech, Giovanni; Greguras, Stjepan; Ivanovic, Iva; Guevara, Kaloyan; Kakar, Selay; Kotsis, Konstantinos; Ingeholm Klinkby, Ida Maria; Maslak, Jovana; Matheiken, Shevonne; Mirkovic, Ana; Nechepurenko, Nikita; Panayi, Angelis; Pereira, Ana Telma Fernandes; Pomarol-Clotet, Edith; Raaj, Shaeraine; Prelog, Polona Rus; Soler-Vidal, Joan; Strumila, Robertas; Schuster, Florian; Kisand, Helena; Reim, Ann; Ahmadova, Gumru; Vircik, Matus; Yılmaz Kafalı, Helin; Grinko, Natalia; Győrffy, Zsuzsa; Rózsa,SándorBackground Mental health-related stigma occurs among the public and professionals alike. The lived experience of mental illness has been linked to less stigmatising attitudes. However, data on psychiatrists and the relationship between stigmatising attitudes and psychotherapeutic activity or case discussion groups remains scarce.Methods A cross-sectional multicentre study was performed in 32 European countries to investigate the lived experiences and attitudes of psychiatrists toward patients with mental illness as well as the relationship between stigma, psychosocial and professional factors. The self-reported, anonymous, internet-based Opening Minds Stigma Scale for Health Care Providers was used to measure the stigmatising attitudes. The survey was translated into the local language of each participating country. All participants were practising specialists and trainees in general adult or child and adolescent psychiatry. The study took place between 2nd October, 2019 and 9th July, 2021 and was preregistered at ClinicalTrial.gov (NCT04644978).Findings A total of 4245 psychiatrists completed the survey. The majority, 2797 (66%), had completed training in psychiatry, and 3320 (78%) worked in adult psychiatry. The final regression model showed that across European countries more favourable attitudes toward people with mental illness were statistically significantly associated with the lived experience of participants (including seeking help for their own mental health conditions (d = -0.92, 95% confidence interval (CI) = -1.68 to -0.15, p = 0.019), receiving medical treatment for a mental illness (d = -0.88, 95% CI = -1.71 to -0.04, p = 0.040), as well as having a friend or a family member similarly affected (d = -0.68, 95% CI = -1.14 to -0.22, p = 0.004)), being surrounded by colleagues who are less stigmatising (d = -0.98, 95% CI = -1.26 to -0.70, p < 0.001), providing psychotherapy to patients (d = -1.14, 95% CI = -1.63 to -0.65 p < 0.001), and being open to (d = -1.69, 95% CI = -2.53 to -0.85, p < 0.001) and actively participating in (d = -0.94, 95% CI = -1.45 to -0.42, p < 0.001) case discussion, supervision, or Balint groups.Interpretation Our study highlights the importance of psychotherapy training, supervision, case discussions and Balint groups in reducing the stigmatising attitudes of psychiatrists toward patients. As the findings represent cross -national predictors, Europe-wide policy interventions, national psychiatric education systems and the management of psychiatric institutions should take these findings into consideration.Funding National Youth Talent Award (Ministry of Human Resources, Hungary, (NTP-NFTo-20-B-0134).

Although language-related symptoms such as disorganized speech were predicted by the polygenic risk for SZ which emphasized the common genetic liability for the disease, few studies investigated possible white matter integrity abnormalities in the language-related tracts in those at familial high-risk for SZ. Also, their results are not consistent. In this current study, we examined possible aberrations in language-related white matter tracts in patients with first-episode psychosis (FEP, N = 20), their siblings (SIB, N = 20), and healthy controls (CON, N = 20) by applying whole-brain Tract-Based Spatial Statistics and region-of-interest analyses. We also assessed language ability by Thought and Language Index (TLI) using Thematic Apperception Test (TAT) pictures and verbal fluency to see whether the scores of these language tests would predict the differences in these tracts. We found significant alterations in language-related tracts such as inferior longitudinal fasciculus (ILF) and uncinate fasciculus (UF) among three groups and between SIB and CON. We also proved partly their relationship with the language test as indicated by the significant correlation detected between TLI Impoverished thought/language sub-scale and ILF. We could not find any difference between FEP and CON. These results showed that the abnormalities, especially in the ILF and UF, could be important pathophysiological vulnerability indexes of schizophrenia. Further studies are required to understand better the role of language as a possible endophenotype in schizophrenia with larger samples.Yayın Formal thought disorder and familial risk in first-episode psychosis: A study of cortical thickness and neuroimaging-transcriptomic association analysis(Elsevier Ireland Ltd, 2026-01-16) Çabuk, Tuğçe; Zhang, Yuanchao; Palaniyappan, Lena; Şahin Çevik, Didenur; Avcı, Hanife; Çakmak, Işık Batuhan; Yılmaz Kafalı, Helin; Şenol, Bedirhan; Karlı Oğuz, Kader; Toulopoulou, TimotheaFormal thought disorder (FTD), a prominent feature of schizophrenia, encompasses disruptions in thought, language, and communication. This study examines cortical thickness (CT) alterations in first-episode psychosis (FEP) patients (N = 24), their siblings (SIB) (N = 21), and healthy controls (CON) (N = 21) to explore potential neural correlates of FTD. Using structural MRI, we analyzed whole-brain CT and its relationship with positive and negative FTD measured by Thought and Language Index. Out-of-sample spatial correlations of gene expression with regional CT were also performed using a transcriptomic dataset. FEP had significant CT reductions in right middle frontal gyrus (MFG) compared with SIB and CON and in superior frontal gyrus (SFG) compared to CON; but SIB did not differ from CON. GLM analyses demonstrated that negative FTD exerted a significant main effect on CT in the MFG and SFG. By contrast, positive FTD showed no significant associations with CT. Neuroimaging-transcriptomic association analysis identified key biological pathways linked to cortical morphology. These findings emphasize the specific association between negative FTD and CT alterations in frontal brain regions, confirming prior reports. Future research should examine larger cohorts and investigate additional FTD subtypes to further elucidate neural correlates and potential familial risks of schizophrenia.
