Item Relationship Among Coping Strategies, Quality of Life, and Anxiety and Depressive Disorders in Hemodialysis Patients(2019) Ulusoy, Selen Isik; Kal, Oznur; 0000-0003-2550-8989; 31233289Patients with hemodialysis face many physical and emotional stressors; yet little is known regarding coping strategies and their effects on patients' quality of life (QOL) and anxiety and depressive disorders. A total of 117 patients were enrolled in this cross-sectional study between October 2016 and April 2017. This study assessed QOL (Medical outcome short form 36-MOS 36), coping (Assessment Scale for Coping Attitudes-COPE) and psychiatric comorbidities in hemodialysis patients. Beck Depression Scale and Beck Anxiety Scale were also applied. Differences between groups were evaluated using Student's t-tests and anova. Correlations among parameters were performed. Patients with any depressive disorder (22.2%, n = 26) and patients with any anxiety disorder (19.6%, n = 23) reported more impaired QOL. The most frequently used coping strategy in all patients was religious coping. Use of instrumental social support, humor, and positive reinterpretation scores were lower in patients with any depressive disorder (P = 0.009, P = 0.034, P = 0.047).The total score of emotion-focused coping strategies was lower with patients with any depressive disorder (P = 0.021) and emotion-focused coping strategies were positively correlated with QOL scores. Younger age and longer duration of hemodialysis have significant negative correlation with emotion-focused coping strategies' total score (P = 0.01, P = 0.02). Patients with hemodialysis use variety of coping strategies. The use of emotion-focused coping was associated with better QOL and reducing the risk of depressive disorder. Interventions to facilitate the use of adaptive coping strategies may improve patients' QOL and mood.Item Evaluation of choroidal and retinal thickness measurements in adult hemodialysis patients using spectral-domain optical coherence tomography(2016) Kal, Ali; Kal, Oznur; Eroglu, Fatma Corak; Omer, Ozlem; Kucukdonmez, Cem; Yilmaz, Gursel; 0000-0002-2589-7294; 0000-0003-3003-0756; 27626146; AAK-6987-2021; D-5308-2015Purpose: To assess the effect of hemodialysis on retinal and choroidal thicknesses using spectral-domain optical coherence tomography (SD-OCT). Methods: In this prospective interventional study, 25 hemodialysis patients (17 male, 8 female) were enrolled. All participants underwent high-speed, high-resolution SD-OCT (lambda=840 mm; 26.000 A-scans/s; 5 mu m resolution) before and after hemodialysis. Choroidal thickness was measured perpendicularly from the outer edge of the retinal pigment epithelium to the choroid-sclera boundary at the fovea and at five additional points: 500 mu m and 1000 mu m nasal to the fovea and 500 mu m, 1000 mu m, and 1500 mu m temporal to the fovea. Two masked physicians performed the measurements. Choroidal and retinal thicknesses before and after hemodialysis were compared. Results: The median choroidal thicknesses before and after hemodialysis were 182 mu m (range, 103-374 mu m) and 161 mu m (range, 90-353 mu m), respectively (P<0.001). The median retinal thicknesses were 246 mu m (range, 179-296 mu m) before and 248 mu m (range, 141-299 mu m) after hemodialysis (P>0.05). Systolic arterial pressure, diastolic arterial pressure, mean arterial pressure, heart rate, and ocular perfusion pressure significantly decreased after hemodialysis (P<0.001). Intraocular pressure did not vary significantly (P=0.540). Conclusion: Hemodialysis seems to cause a significant decrease in choroidal thickness, whereas it has no effect on retinal thickness. This significant decrease in choroidal thickness might be due to the extensive fluid absorption in hemodialysis, which could result in decreased ocular blood flow.
