    The examinations of achene ultrastructural features of section Acrolophus (Centaurea, Asteraceae) via scanning electron microscopy
    (Turkiye Klinikleri Journal of Medical Sciences, 2016) Candan F.; Uysal T.; Tugay O.; Bozkurt M.; Ertuğrul K.; Demirelma H.
    In this study, the achene surfaces of 31 taxa belonging to the genus Centaurea L. were examined in detail by means of electron microscopy. The main aim of this study was to characterize the microsculpture of the achene surface of the Turkish species of Centaurea sect. Acrolophus (Cass.) DC. (Asteraceae). Detailed descriptions of the achene surface were given for each taxon and a fruitful dendrogram was established by numerical analyses derived from the determined micromorphological features. The relationships among the taxa studied were briefly assessed using this generated dendrogram. The results indicated that the examined taxa had very high variations regarding their achene surfaces and these variations have great importance in determining the taxonomic relationships of the discussed taxa. According to the results, pericarp texture and color could be used for taxonomical diagnosis of the Acrolophus species because they contain differences over a broad spectrum. The fruit coat was usually roguish and its ornamentation was fairly variable; therefore, this taxonomical microcharacter might also be useful in distinguishing closely related taxa. The hairiness of the surface of the pericarp was characteristic in all Acrolophus species and it would be evaluated as a decisive micromorphological character of the section within the genus. © TÜBİTAK.

    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

    (Taylor and Francis Ltd, 2019) Ercan E.S.; Polanczyk G.; Akyol Ardıc U.; Yuce D.; Karacetın G.; Tufan A.E.; Tural U.; Aksu H.; Aktepe E.; Rodopman Arman A.; Başgül S.; Bılac O.; Coşkun M.; Celık G.G.; Karakoc Demırkaya S.; Dursun B.O.; Durukan İ.; Fidan T.; Perdahlı Fiş N.; Gençoğlan S.; Gökçen C.; Görker I.; Görmez V.; Gündoğdu Ö.Y.; Gürkan C.K.; Hergüner S.; Tural Hesapçıoğlu S.; Kandemir H.; Kılıç B.G.; Kılınçaslan A.; Mutluer T.; Nasiroğlu S.; Özel Özcan Ö.; Öztürk M.; Öztop D.; Yalın Sapmaz S.; Süren S.; Şahin N.; Yolga Tahıroglu A.; Toros F.; Ünal F.; Vural P.; Perçinel Yazıcı İ.; Yazıcı K.U.; Yıldırım V.; Yulaf Y.; Yüce M.; Yüksel T.; Akdemir D.; Altun H.; Ayık B.; Bilgic A.; Hekim Bozkurt Ö.; Demirbaş Çakır E.; Çeri V.; Üçok Demir N.; Dinç G.; Irmak M.Y.; Karaman D.; Kınık M.F.; Mazlum B.; Memik N.Ç.; Foto Özdemir D.; Sınır H.; Ince Taşdelen B.; Taşkın B.; Uğur Ç.; Uran P.; Uysal T.; Üneri Ö.; Yilmaz S.; Seval Yılmaz S.; Açıkel B.; Aktaş H.; Alaca R.; Alıç B.G.; Almaidan M.; Arı F.P.; Aslan C.; Atabay E.; Ay M.G.; Aydemir H.; Ayrancı G.; Babadagı Z.; Bayar H.; Çon Bayhan P.; Bayram Ö.; Dikmeer Bektaş N.; Berberoğlu K.K.; Bostan R.; Arıcı Canlı M.; Cansız M.A.; Ceylan C.; Coşkun N.; Coşkun S.; Çakan Y.; Demir İ.; Demir N.; Yıldırım Demirdöğen E.; Doğan B.; Dönmez Y.E.; Dönder F.; Efe A.; Eray Ş.; Erbilgin S.; Erden S.; Ersoy E.G.; Eseroğlu T.; Kına Fırat S.; Eynallı Gök E.; Güler G.; Güles Z.; Güneş S.; Güneş A.; Günay G.; Gürbüz Özgür B.; Güven G.; Çelik Göksoy Ş.; Horozcu H.; Irmak A.; Işık Ü.; Kahraman Ö.; Kalaycı B.M.; Karaaslan U.; Karadağ M.; Kılıc H.T.; Kılıçaslan F.; Kınay D.; Kocael Ö.; Bulanık Koç E.; Kadir Mutlu R.; Lushi-Şan Z.; Nalbant K.; Okumus N.; Özbek F.; Akkuş Özdemir F.; Özdemir H.; Özkan S.; Yıldırım Özyurt E.; Polat B.; Polat H.; Sekmen E.; Sertçelik M.; Sevgen F.H.; Sevince O.; Süleyman F.; Shamkhalova Ü.; Eren Şimşek N.; Tanır Y.; Tekden M.; Temtek S.; Topal M.; Topal Z.; Türk T.; Uçar H.N.; Uçar F.; Uygun D.; Uzun N.; Vatansever Z.; Yazgılı N.G.; Miniksar Yıldız D.; Yıldız N.
    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.

    Serum hypoxia-inducible factor-2: A candidate prognostic biomarker for laryngeal cancer
    (John Wiley and Sons Inc, 2021) Eskiizmir G.; Çalıbaşı Koçal G.; Uysal T.; Ellidokuz H.; Başpınar Y.
    Objectives: To determine the serum hypoxia-inducible factor-1, -2 and -3 (HIF-1, -2 and -3) levels in patients with laryngeal neoplasm, and to investigate their role in differential diagnosis, prediction of tumour characteristic and extension, and prognosis and survival. Study Design: Prospective, cohort study at a tertiary referral centre. Settings: The study was conducted in a tertiary medical centre. Participants: Patients with benign, premalignant and malignant laryngeal neoplasms were included. Sixty-four patients with a laryngeal neoplasm were enrolled. Main Outcome Measures: Serum HIF-1, -2 and -3 levels were measured from blood samples that were drawn before treatment, using ELISA. Results: A statistically significant difference between benign (HIF-1, -2, -3:4046,1 pg/mL; 2581,5 pg/mL; 1321,0 pg/mL), premalignant (HIF-1, -2, -3:3630,3 pg/mL; 3229,7 pg/mL; 2549,8 pg/mL) and malignant (HIF-1, -2, -3:3576,7 pg/mL; 2595,8 pg/mL; 1106,3 pg/mL) laryngeal neoplasms was not detected when serum HIF-1, -2 and -3 levels were compared. However, high serum HIF-2 level adversely affected survival and locoregional control and had more than 7-fold increase in hazard ratio. Moreover, serum HIF-2 was an independent prognostic factor for 2-year overall, disease-free, distant metastasis-free survival and locoregional control. Conclusion: This is the first clinical study in which the diagnostic, predictive and prognostic roles of hypoxia-related biomolecules were examined in laryngeal neoplasms. Hypoxia-inducible factor-2 is a prognostic factor in larynx cancer irrespective of treatment modality. © 2021 John Wiley & Sons Ltd.

    Who predict ADHD with better diagnostic accuracy?: Parents or teachers?
    (Taylor and Francis Ltd., 2021) Tahıllıoğlu A.; Bilaç Ö.; Uysal T.; Ercan E.S.
    Objective: The objectives of the study were to determine which parents or teachers predict attention-deficit/hyperactivity disorder (ADHD) better in children and adolescents, and to detect both diagnostical and symptomatological agreement levels across informant reports. Method: A total of 417 cases aged 6–14 from a non-referred community sample were assessed by a semi-structured interview, parent- and teacher-rated ADHD Rating Scale-IV. Also, impairment criteria were taken into account to ensure the gold standard diagnosis for ADHD. The measures of sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy were calculated in each categorical sample. Besides, the agreement between parent and teacher reports of ADHD was investigated. Results: Parents and teachers had similar diagnostic accuracy for predicting ADHD. Both parents and teachers predicted ADHD in similar accuracy in both boys and girls, separately. However, girls were found to be more predictable by both parents and teachers compared to boys. Parents with lower education levels had worse diagnostic accuracy than both parents with higher education levels and teachers. Low to moderate agreement and correlations between parent and teacher ADHD reports were detected. Conclusion: In general, parents and teachers seem to predict ADHD in similar accuracy. Nevertheless, child gender and parental education level may alter the predictability power for ADHD. The findings can guide for clinicians that how to evaluate observation reports of parents and teachers to make accurate ADHD diagnosis in patients. © 2021 The Nordic Psychiatric Association.

    ADHD and its associations with pregnancy, birth, developmental and medical-related characteristics
    (Springer, 2023) Yüksel A.E.; Doğan N.; Tahıllıoğlu A.; Bilaç Ö.; Uysal T.; Ercan E.S.
    This study aimed to examine possible associations between Attention-Deficit/Hyperactivity Disorder (ADHD) and pregnancy-related, birth-related, developmental, medical, and surgical history characteristics. The sample was derived from a non-referred community sample aged 6 to 14. 91 cases with ADHD and 264 without any psychopathology were compared in terms of psychological and physical problems in pregnancy, mode of delivery, birth complications, developmental stages, injuries, medical and surgical diseases. A semi-structured clinical interview was applied to diagnose the children. ADHD Rating Scale-IV (ADHD-RS-IV) was completed by the parents. Male gender, delay in talking time, and physical injury history predicted increased risks for ADHD. Although having any surgery, and in particular, tonsillectomy did not predict ADHD, inguinal hernia surgery alone predicted an increased risk for ADHD even when controlled for gender. Psychological problems during pregnancy were associated with elevated inattention (IN) and hyperactivity-impulsivity (HI) scores, but not associated with ADHD as a diagnosis. Elevated IN scores but not HI scores were associated with a physical injury history. Although the mode of delivery and physical disease history were not associated with ADHD, asthma increased the likelihood for higher HI scores. The findings have crucial clinical implications that address several points. The findings suggest ADHD may have associations with some negative neurodevelopmental, medical, and surgical history characteristics. The predictivity of inguinal hernia surgery for ADHD might depend on the exposure to general anesthesia at younger ages. Hence, children who had these features should carefully be screened for ADHD. © 2021, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.
