RESUMO

Objective@#This study aims to assess the psychometric values of the Generalized Anxiety Disorder Scale-Revised (GADS-R) which measures the intensity and duration of worry, various coping and avoidance strategies to cope with worrying, and positive and negative metacognitive beliefs about worrying. @*Methods@#114 patients with generalized anxiety disorder and 198 healthy controls were included in the study. These patients were diagnosed according to DSM-IV TR, and the primary diagnosis of the patients was generalized anxiety disorder which was confirmed via SCID I and II, subsequently. Sociodemographic form, GADS-R total and subscale scores, and Meta-Cognitions Questionnaire-30 (MCQ-30), Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Generalized Anxiety Disorder-7 Scale (GAD-7), and Penn State Worry Questionnaire (PSWQ) were used to assess validity, reliability and cut-off point. @*Results@#GADS-R total and subscale scores and MCQ-30, BDI, BAI, GAD-7, and PSWQ were found to be statistically higher in the patients with GAD compared to a healthy control group. GADS-R has five factors and showed relatively acceptable sensitivity and specificity for detecting anxiety disorders at a cut-off point of 1188. @*Conclusion@#The GADS-R is a valid and reliable scale that can be used in the Turkish population as an assessment tool.

RESUMO

OBJECTIVE: This study aimed to evaluate the reliability and validity of the Turkish version of Cognitive Attentional Syndrome-1 (CAS-1) questionnaire. METHODS: 221 participants were included in the study who do not meet any psychiatric diagnosis. Participants were applied SCID I and II and filled CAS-1 scale, Meta-Cognitions Questionnaire-30 (MCQ-30), Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Generalized Anxiety Disorder-7 (GAD-7) Scale, and Penn State Worry Questionnaire (PSWQ). Testing the reliability Cronbach’s alpha, item analysis and Item and total score correlation coefficients were applied. For testing structural validity, Confirmatory Factor Analysis was used, and for testing the content validity, the relationship between each item of CAS-1 and MCQ-30, BDI, BAI, GAD-7, PSWQ was examined. RESULTS: The correlation reliability coefficients were statistically significant except for using alcohol/drugs as a coping mechanism. Cronbach Alpha reliability coefficient of 16 items was 0.771 whereas, this ratio was 0.772 for the first eight items (CAS) and 0.685 for the last eight items (Metacognitive Beliefs) which showed that the internal consistency of CAS-1 was high. Structural and Content Validity of the scale was significant. CONCLUSION: The Turkish version of the CAS-1 was a reliable and valid measure to evaluate CAS in a Turkish population.

RESUMO

BACKGROUND: Microvascular anastomosis patency is adversely affected by local and systemic factors. Impaired intimal recovery and endothelial mechanisms promoting thrombus formation at the anastomotic site are common etiological factors of reduced anastomosis patency. Epigallocatechin gallate (EGCG) is a catechin derivative belonging to the flavonoid subgroup and is present in green tea (Camellia sinensis). This study investigated the effects of EGCG on the structure of vessel tips used in microvascular anastomoses and evaluated its effects on thrombus formation at an anastomotic site. METHODS: Thirty-six adult male Wistar albino rats were used in the study. The right femoral artery was cut and reanastomosed. The rats were divided into two groups (18 per group) and were systemically administered either EGCG or saline. Each group were then subdivided into three groups, each with six rats. Axial histological sections were taken from segments 1 cm proximal and 1 cm distal to the microvascular anastomosis site on days 5, 10, and 14. RESULTS: Thrombus formation was significantly different between the EGCG and control groups on day 5 (P=0.015) but not on days 10 or 14. The mean luminal diameter was significantly greater in the EGCG group on days 5 (P=0.002), 10 (P=0.026), and 14 (P=0.002). Intimal thickening was significantly higher on days 5 (P=0.041) and 10 (P=0.02). CONCLUSIONS: EGCG showed vasodilatory effects and led to reduced early thrombus formation after microvascular repair. Similar studies on venous anastomoses and random or axial pedunculated skin flaps would also contribute valuable findings relevant to this topic.
