The Effect of Reiki and Aromatherapy on Vital Signs, Oxygen Saturation, and Anxiety Level in Patients Undergoing Upper Gastrointestinal Endoscopy: A Randomized Controlled Study Keşer, Esra; Samancıoğlu Bağlama, Sevgin; Sezer, Cem This randomized controlled study aimed to determine the effect of Reiki and aromatherapy on vital signs, oxygen saturation, and anxiety level in patients undergoing upper gastrointestinal endoscopy. The sample consisted of 100 patients divided into Reiki (n = 34), aromatherapy (n = 33), and control (n = 33) groups. Data were collected 3 times (before, during, and after the procedure) using a descriptive characteristics questionnaire, a follow-up form, and the State Anxiety Subscale. The Reiki group had a mean State Anxiety Subscale score of 53.59 ± 2.98 and 43.94 ± 4.31 before and after the procedure, respectively. The aromatherapy group had a mean State Anxiety Subscale score of 54.03 ± 4.03 and 43.85 ± 3.91 before and after the procedure, respectively. The control group had a mean State Anxiety Subscale score of 38.79 ± 4.68 and 53.30 ± 7.26 before and after the procedure, respectively (P < .05). The results showed that the Reiki and aromatherapy groups had significantly lower State Anxiety Subscale scores than the control group after the procedure, indicating that Reiki and aromatherapy help reduce anxiety levels. There was a significant difference in the mean respiratory rates and oxygen saturation levels between the groups (P < .05). In conclusion, patients who do Reiki or undergo aromatherapy are less likely to experience anxiety before upper gastrointestinal endoscopy.

Effect of levetiracetam on ocular perfusion measure with optical coherence tomography angiography Kaderli, Ahmet; Kayılıoğlu, Hülya; Kaderli, Sema Tamer; Karalezli, Aylin Purpose: To evaluate using optical coherence tomography angiography the macular and optic nerve head blood flow in pediatric patients with epilepsy treated with levetiracetam for at least 12 months. Methods: This study included 33 pediatric patients with epilepsy and 30 sex- and age-matched healthy volunteer children were included in the study. Optical coherence tomography angiography was used to evaluate the optic nerve head and macular perfusion changes. The mean ocular perfusion pressures were also calculated. Patients who were using multiple antiepileptic drugs or had a prior history of using different drugs were excluded. Results: The choriocapillaris flow area was significantly lower in the Study Group than in the Control Group (p=0.006). However, the foveal avascular zone and vessel densities of the macula in the superficial capillary plexus, deep capillary plexus, and optic nerve head of the study group were not significantly different from those of the control group (p>0.05). Moreover, no significant difference in means of mean ocular perfusion pressure was found between the two groups (p=0.211). No obvious correlation was found between treatment duration and optical coherence tomography angiography parameters or mean ocular perfusion pressure. Conclusion: Choroidal perfusion was reduced in children taking levetiracetam compared with that in the control group, whereas retinal perfusion was not affected in this optical coherence tomography angiography study.

Effect of Foam-mat Drying on Bioactive, Powder and Thermal Properties of Carrot Juice Powders

Effect of Foam-mat Drying on Bioactive, Powder and Thermal Properties of Carrot Juice Powders Çakmak, Hülya; Özyurt, Vasfiye Hazal Foam-mat drying is a promising method due to involvement of proteins as foaming agent which acts like a wall material wrapping around bioactives and retards their degradation. In this study, powder properties of foam-mat dried carrot juice powders including 15% egg albumen (EA) and 15% egg albumen+ 10% whey protein isolate (WPI) during 90 days of storage at room conditions were evaluated by means of physical, chemical, thermal (DSC and TGA) and microstructural (SEM) analyses. The powder flow properties (wettability, hygroscopicity, degree of caking, Carr index and Hausner ratio) have been significantly affected from the moisture uptake during storage; however, powder flow properties of 15% EA+ 10% WPI powders were found to be better than 15% EA powders as it was also confirmed by particle diameter distributions that remained the same before and after the storage period. Besides, the total antioxidant, phenolic and carotenoid contents of 15% EA+ 10% WPI carrot powder was found comparably higher than 15% EA powders due to possible encapsulating mechanism of whey proteins. In addition to delaying of physical and chemical deteriorations in powders with WPI incorporation, thermal stability of the foam-mat dried carrot juice powders was also improved in 15% EA+ 10% WPI powder.

Optic nerve head vascular variations in pseudoexfoliative and primary open-angle glaucoma

Optic nerve head vascular variations in pseudoexfoliative and primary open-angle glaucoma Karabulut, Müjdat; Karabulut, Sinem; Kaderli, Ahmet; Sül, Sabahattin; Karalezli, Aylin Purpose: The purpose of this study was to assess the optic nerve head microvascular changes in pseudoexfoliative and primary open-angle glaucoma and define the relationship between vessel density and retinal nerve fiber layer thickness. Methods: This observational cross-sectional study assessed 72 eyes with primary open-angle glaucoma, 41 eyes with pseudoexfoliative glaucoma, and 60 healthy eyes. On the basis of optic nerve head-centered, 4.5 mm × 4.5 mm scan size images, we evaluated the vessel density, as well as the peripapillary sector, inside disk, and all sectoral quadrants. Results: Both glaucoma Groups had lower vessel density in all regions compared with the healthy Group (p<0.05 for all variables). Vessel densities of the nasal inferior, inferior nasal, and inferior temporal sectors in both glaucoma Groups showed similar results (p=0.157, p=0.128, p=0.143, respectively). Eyes with pseudoexfoliative glaucoma had significantly lower vessel densities than eyes with primary open-angle glaucoma in all other regions (p<0.05 for all variables). For both glaucoma Groups, the average retinal nerve fiber layer thickness positively correlated with vessel density in all peripapillary sectors (p<0.05 for all variables). Conclusions: Reduction in vessel density correlated with the thinning of retinal nerve fiber layer in both glaucoma Groups. Decreased vessel density in the optic nerve head can be used to demonstrate the microvascular pathologies and possible ischemic changes that lead to faster progression and worse prognosis in pseudoexfoliative glaucoma.
