    (2011) Özden M.G.; Tekin N.S.; Gürer M.A.; Akdemir D.; Doǧramaci Ç.; Utaş S.; Akman A.; Evans S.E.; Bahadir S.; Öztürkcan S.; Ikizoǧlu G.; Şendur N.; Köse O.; Bek Y.; Yayli S.; Cantürk T.; Turanl A.Y.
    To analyze the effect of possible risk factors, including breastfeeding, on the development of childhood-onset psoriasis, a multicenter case-control study with prospective collection of data was performed. Using a standard questionnaire, personal and specific variables including family history of psoriasis, maternal and environmental tobacco smoke exposure, body mass index (BMI), exclusive and partial breastfeeding for at least 3 and 12 months, cow's milk intake before 1 year, birth delivery method, and stressful life events were collected during 2009 from 537 patients with psoriasis and 511 controls younger than 18. Overall, patients more frequently reported exposure to environmental tobacco smoke at home and stressful life events in the year preceding the diagnosis than controls. The odds ratios (OR) for smoking and stressful life events were 2.90 (95% confidence interval [CI] = 2.27-3.78) and 2.94 (95% CI = 2.28-3.79), respectively. In addition, children with psoriasis were more likely to have a higher BMI (>26) than controls (OR = 2.52; 95% CI = 1.42-4.49). High BMI, environmental tobacco smoke exposure at home, and stressful life events may influence the development of pediatric psoriasis. © 2011 Wiley Periodicals, Inc.

    Aim: To determine the prevalence of affective disorders in Turkey among a representative sample of Turkish population. Methods: This study was conducted as a part of the “The Epidemiology of Childhood Psychopathology in Turkey” (EPICPAT-T) Study, which was designed by the Turkish Association of Child and Adolescent Mental Health. The inclusion criterion was being a student between the second and fourth grades in the schools assigned as study centers. The assessment tools used were the K-SADS-PL, and a sociodemographic form that was designed by the authors. Impairment was assessed via a 3 point-Likert type scale independently rated by a parent and a teacher. Results: A total of 5842 participants were included in the analyses. The prevalence of affective disorders was 2.5 % without considering impairment and 1.6 % when impairment was taken into account. In our sample, the diagnosis of bipolar disorder was lacking, thus depressive disorders constituted all the cases. Among depressive disorders with impairment, major depressive disorder (MDD) (prevalence of 1.06%) was the most common, followed by dysthymia (prevalence of 0.2%), adjustment disorder with depressive features (prevalence of 0.17%), and depressive disorder-NOS (prevalence of 0.14%). There were no statistically significant gender differences for depression. Maternal psychopathology and paternal physical illness were predictors of affective disorders with pervasive impairment. Conclusion: MDD was the most common depressive disorder among Turkish children in this nationwide epidemiological study. This highlights the severe nature of depression and the importance of early interventions. Populations with maternal psychopathology and paternal physical illness may be the most appropriate targets for interventions to prevent and treat depression in children and adolescents. © 2018

    Aim: The aim of this study was to determine the prevalence of childhood psychopathologies in Turkey. Method: A nation-wide, randomly selected, representative population of 5830 children (6–13 years-old) enrolled as a 2nd,3rd or 4th grade student in 30 cities were evaluated for presence of a psychiatric or mental disorder by a Sociodemographic Form, Kiddie Schedule for Affective Disorders and Schizophrenia for School Age Children-Present and Lifetime Version (K-SADS-PL), and DSM-IV-Based Screening Scale for Disruptive Behavior Disorders in Children and Adolescents scales. Impairment criterion was assessed via a 3 point-Likert scale by the parent and the teacher independently. Results: Overall prevalence of any psychopathology was 37.6% without impairment criterion, and 17.1% with impairment criterion. Attention-deficit hyperactivity disorder was the most frequent diagnosis, followed by anxiety (19.5% and 16.7% without impairment, 12.4% and 5.3% with impairment, respectively). Lower education level and presence of a physical or psychiatric problem of the parents were independent predictors of any psychopathology of the offspring. Conclusion: This is the largest and most comprehensive epidemiological study to determine the prevalence of psychopathologies in children and adolescents in Turkey. Our results partly higher than, and partly comparable to previous national and international studies. It also contributes to the literature by determining the independent predictors of psychopathologies in this age group. © 2019, © 2019 The Nordic Psychiatric Association.

    Genome wide association study of 5 agronomic traits in olive (Olea europaea L.)
    (Nature Research, 2019) Kaya H.B.; Akdemir D.; Lozano R.; Cetin O.; Sozer Kaya H.; Sahin M.; Smith J.L.; Tanyolac B.; Jannink J.-L.
    Olive (Olea europaea L.) is one of the most economically and historically important fruit crops worldwide. Genetic progress for valuable agronomic traits has been slow in olive despite its importance and benefits. Advances in next generation sequencing technologies provide inexpensive and highly reproducible genotyping approaches such as Genotyping by Sequencing, enabling genome wide association study (GWAS). Here we present the first comprehensive GWAS study on olive using GBS. A total of 183 accessions (FULL panel) were genotyped using GBS, 94 from the Turkish Olive GenBank Resource (TOGR panel) and 89 from the USDA-ARS National Clonal Germplasm Repository (NCGR panel) in the USA. After filtering low quality and redundant markers, GWAS was conducted using 24,977 SNPs in FULL, TOGR and NCGR panels. In total, 52 significant associations were detected for leaf length, fruit weight, stone weight and fruit flesh to pit ratio using the MLM_K. Significant GWAS hits were mapped to their positions and 19 candidate genes were identified within a 10-kb distance of the most significant SNP. Our findings provide a framework for the development of markers and identification of candidate genes that could be used in olive breeding programs. © 2019, The Author(s).

    Effect of Impairment on the Prevalence and Comorbidities of Attention Deficit Hyperactivity Disorder in a National Survey: Nation-Wide Prevalence and Comorbidities of ADHD
    (SAGE Publications Inc., 2022) Ercan E.S.; Unsel-Bolat G.; Tufan A.E.; Karakoc Demirkaya S.; Bilac O.; Celik G.; Kılıç B.G.; Akyol Ardic U.; Yalin Sapmaz S.; Aksu H.; Yolga Tahiroglu A.; Karacetin G.; Tural U.; Aktepe E.; Rodopman Arman A.; Başgül S.; Coşkun M.; Dursun O.B.; Durukan İ.; Perdahli Fiş N.; Gençoğlan S.; Gökçen C.; Sarı Gokten E.; Görker I.; Görmez V.; Yıldız Gündoğdu Ö.; Hesapçioğlu S.T.; Kandemir H.; Mutluer T.; Nasiroğlu S.; Özcan Ö.; Şahin N.; Toros F.; Perçinel Yazici İ.; Yazici K.U.; Yulaf Y.; Yüksel T.; Bilgic A.; Altun H.; Akdemir D.; Mazlum B.; Çakın Memik N.; Foto Özdemir D.; Üneri Ö.; Ünal F.
    Objective: This study aimed to determine the prevalence and comorbidities of attention-deficit hyperactivity disorder (ADHD) by evaluating a large-scale nation-wide sample of children. Method: The inclusion criterion was being enrolled as a 2nd, 3rd, or 4th-grade student. A semi-structured diagnostic interview (K-SADS-PL), DSM-IV-Based Screening Scale for Disruptive Behavior Disorders, and assessment of impairment (by both parents and teachers) were applied to 5,842 participants. Results: The prevalence of ADHD was 19.5% without impairment and 12.4% with impairment. Both ADHD with and without impairment groups had similar psychiatric comorbidity rates except for oppositional defiant disorder (ODD) and conduct disorder (CD) diagnoses. Impairment in the ADHD group resulted in significantly higher ODD and CD diagnoses. Conclusion: Even when impairment is not described, other psychiatric disorders accompany the diagnosis of ADHD and may cause impairment in the future. Impairment in the diagnosis of ADHD significantly increases the likelihood of ODD and CD. © ©The Author(s) 2021.

    (Springer Science and Business Media Deutschland GmbH, 2023) Mutluer T.; Gorker I.; Akdemir D.; Ozdemir D.F.; Ozel O.O.; Vural P.; Tufan A.E.; Karacetin G.; Arman A.R.; Fis N.P.; Demirci E.; Ozmen S.; Hesapcioglu S.T.; Oztop D.; Tural U.; Aktepe E.; Aksu H.; Ardic U.A.; Basgul S.; Bilac O.; Coskun M.; Celik G.G.; Demirkaya S.K.; Dursun O.B.; Durukan I.; Fidan T.; Gokcen C.; Gormez V.; Gundogdu O.Y.; Herguner S.; Kandemir H.; Kilic B.G.; Kilincaslan A.; Nasiroglu S.; Sapmaz S.Y.; Sahin N.; Tahiroglu A.Y.; Toros F.; Unal F.; Yazici I.P.; Yazici K.U.; Isik U.; Ercan E.S.
    Purpose: The aim of this study is to evaluate the prevalence of anxiety disorders, its correlation with sociodemographic characteristics, its comorbidities with other psychiatric disorders and its predictors in school-aged children. Methods: This study is part of a representative, multi-centered national study that is planned by the Turkish Association of Child and Adolescent Mental Health to evaluate the prevalence of psychopathology among elementary school students in Turkey between the years 2014–2015. Children are screened via Kiddie Schedule for Affective Disorders and Schizophrenia for School Age Children Present and Lifetime Version. Impairment is assessed by a 3-point Likert type scale independently by the parent and the teacher. The final sample included 5842 children with the mean age of 8.7 years. Results: The prevalence of any anxiety disorder without considering impairment is 16.7% and considering impairment is 5.2% in children according to our study. We found significant differences for comorbid Attention Deficit Hyperactivity Disorder, Disruptive Behavior Disorder, Mood Disorders, Tic Disorders, Obsessive Compulsive Disorder, Enuresis Nocturna, Encopresis, and Intellectual Disability. Having a history of paternal physical disorder, living in the regions of Marmara, Mediterranean and Black Sea were found to be the main predictors of having childhood anxiety disorders according to the logistic regression analysis. Conclusion: Better understanding of childhood anxiety disorders, comorbid conditions and predictors will result in earlier diagnosis and more appropriate treatment. © 2022, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany.
