    Oxytocin and Vasopressin Levels and Related Factors in Adolescents with Social Phobia and Other Anxiety Disorders
    (Korean Coll Neuropsychopharmacology, 2022) Uzun, Necati; Akca, Omer Faruk; Kilinc, Ibrahim; Balci, Tevfik
    Objective: This study aimed to determine whether a difference exists in plasma oxytocin and vasopressin levels among social anxiety disorder, other anxiety disorders, and healthy control groups in adolescents. The relationship between several psychiatric variables (i.e., state and trait anxiety, social anxiety, childhood trauma, and behavioral inhibition) and oxytocin or vasopressin levels were also investigated in adolescents with anxiety disorders. Methods: The study included three groups of adolescents: social anxiety disorder (n = 29), those with other anxiety disorders (n = 27), and the control group (n = 28). The participants filled out self-report scales to determine various psychological variables. Oxytocin and vasopressin levels were determined from the blood samples of the participants. Results: The oxytocin levels did not show a significant difference between the social anxiety disorder group and the other anxiety disorders group. However, the oxytocin levels were significantly higher in the social anxiety disorder and other anxiety disorders groups than in the control group. The vasopressin levels did not show a significant difference among the groups. According to the hierarchical regression analysis, the state and trait anxiety levels predicted oxytocin in opposite directions. Oxytocin showed positive and negative relationship with trait and state anxiety respectively. No predictive factors were found for the vasopressin levels. Conclusion: We found that the oxytocin levels of adolescents with social anxiety disorder were not different from those of adolescents with other anxiety disorders. Further studies can improve our knowledge of the relationship among anxiety disorders and oxytocin or vasopressin.

    Prevalence of Hemoglobinopathies in Premarital Screening in the Province of Nigde, Turkey
    (Taylor & Francis Ltd, 2023) Seydel, Gonul Seyda; Ayan, Durmus; Balci, Tevfik; Bayraktar, Muhammet; Gunturk, Inayet
    Hemoglobinopathies are one of the most widespread hereditary disorders in Turkey. The present study aimed to determine the prevalence of hemoglobinopathies in the Nigde province of Turkey. This study was conducted with 2013 individuals who applied for the premarital screening, between January 2019 and December 2021. The complete blood count was measured by an automated hematology analyzer. The types of hemoglobin were determined by high-performance liquid chromatography. A total of 2013 individuals including 951 (47.2%) females and 1062 (52.8%) males, were screened within the premarital screening program, and 67 (3.3%) of them were migrants. 53 out of 2013 (2.63%) individuals were identified as beta thalassemia carriers, and five of them were migrants including two from Afghanistan, two from Iran, and one from Georgia. HbC was observed in two cases, a couple from Syria (0.1%), HbD in two cases (0.1%), HbE in one case from Thailand (0.05%), HbS-beta-thalassemia in one case (0.05%), delta-beta thalassemia in one case (0.05%), and unidentified structural variant in one case (0.05%). Moreover, 183 individuals (9.1%) were considered to have iron deficiency, alpha-thalassemia, or silent beta-thalassemia carrier. These results indicate that the province of Nigde is a relatively risky region regarding hemoglobinopathies. Geographic location and immigrant population may have slightly affected the local prevalence of hemoglobinopathies and could be taken into consideration to ensure the effective implementation of the hemoglobinopathy prevention program.
