Publication Open Access Sleep assessment in preterm infants: Use of actigraphy and aEEG(2022-11-01) BEKİROĞLU, GÜLNAZ NURAL; Ülgen Ö., Barış H. E. , Özbörü Aşkan Ö., Küçük Akdere S., Ilgın C., Özdemir H., Bekiroğlu G. N. , Gücüyener K., Özek E., Boran P.Objective: Objective methods to monitor the sleep of preterm infants at the neonatal intensive care unit (NICU) are required to prevent potentially adverse neurodevelopmental outcomes. This study aimed to determine the concordance of actigraphy and amplitude-integrated electroencephalogram (aEEG) against gold standard direct observation (DO) in assessing sleep/wake states of typically developing preterm infants. Methods: This prospective observational study was conducted in a single center level III NICU. Sleep variables were measured using Philips Respironics Mini-Mitter® Actiwatch-2 for 24 h and compared with 8-h matched data of aEEG and DO. Sensitivity-specificity analysis, Cohen's kappa, prevalenceadjusted and bias-adjusted kappa (PABAK), and Bland Altman plots were generated. Results: Seventeen preterm infants were recruited. A total of 11252 epochs were studied. Sensitivity (86.4%), agreement rate (67.9%), and predictive value for wake (47.9%) for the actigraphy were highest at the automatic activity threshold whereas specificity (54.5%) and predictive value for sleep (75.5%) were highest at low threshold. The sensitivity of aEEG was 79.3% and the specificity was 54.3%. At all thresholds, the agreement was largely equivalent with low kappas (0.14e0.17) and PABAK coefficients (0.22e0.35) for actigraphy and DO. Moderate agreement was observed between aEEG and DO according to the PABAK coefficient (0.44). Mean differences in sleep parameters were not different between DO and aEEG as well as DO/aEEG and actigraphy at medium threshold (p > 0.05). Conclusions: Actigraphy at medium threshold can be used in depicting sleep in typically developing preterm infants at NICU. aEEG may be an alternative adjunctive method to actigraphy for the evaluation of sleep/wake states in the NICU settingPublication Open Access Açık ve laparoskopik kolesistektominin erken postoperatif dönem sıvı faz mide boşalmasına etkileri (ön çalışma)(1996-06-01) BEKİROĞLU, GÜLNAZ NURAL; Günal Ö., Değirmencioğlu L., Çaşkurlu U., Akkaya L., Bekiroğlu G. N.Today, laparoscopic cholecystectomy (LC) as a gold standard operation in the treatment of the gallbladder stones, has not been known enough how it does effect to earty postoperative period (EPP) liquid phase gastric emptying, comparing with the open cholecystectomy (OC). Gastric empyting scintigraphy (Tc 99m-DPTA) has been done to 12 laparoscopically, 6 conventionally treated cholecystectomy patients in prospective, randomized manner. Pre-operative, postoperative 1st and 7th day scintigraphic gastric empyting values (GEVs) were compared with each other. As compared with OC, decreasing GEV in LC at post-op 1st day 60.min was found to be increased at 7th day 0. and 30. min. significantly (p<0.05). However, both LC and OC groups GEVs were found to be statistically the similar levels at 7th day 60. min. We could not find a clinically reasonable difference between the effects of LC and OC on the liquid phase gastric empyting.Publication Open Access Gestational diabetes screening refusal in pregnant women: a cross-sectional survey study(2022-10-01) BEKİROĞLU, GÜLNAZ NURAL; Usal Tarhan N., Ayvacı Taşan H., Çakar E., Bekiroğlu G. N.Objective: Recently, some pregnant women in Türkiye are hesitant to undergo gestational diabetes mellitus (GDM) screening tests and this trend is more common. The objective of the study is to assess the pregnant women’s knowledges, decisions, reasons for hesitations about having the GDM screening tests and test rejection rates. Material and Methods: This cross-sectional study included 647 pregnant women who applied for an antenatal outpatient clinic and who had not yet been diagnosed with GDM and a survey was conducted using questionnaire designed by the authors. Results: At the beginning, 287 (44.4%) of the participants declared that they would have glucose challenge test, 169 (26.1%) would not and 191 (29.5%) were undecided. The rejection rate was lower in those who had knowledge about the screening tests. After a short information about the content of tests, 30% of the women who decided not to have the test and 78.3% of those who were undecided at the beginning, decided to have the test (p=0.001). Conclusion: The knowledge level of pregnant women about diabetes screening and diagnosis influences their decision-making. Organizing well-planned trainings for patients and healthcare professionals using public institutions and media may be effective in reducing the burden of diabetes on social health and the economic indicators.Publication Open Access Morphometric analysis of middle and posterior cranial fossae foramina in 3d reconstructions of ct images: A midline asymmetry evaluation(2022-01-01) VERİMLİ, URAL; BUĞDAYCI, ONUR; BEKİROĞLU, GÜLNAZ NURAL; VERİMLİ U., BUĞDAYCI O., Yildiz S. D., Ozkilic E., BEKİROĞLU G. N., ÖZDOĞMUŞ N. Ö.Objective: The cranial base harbours numerous foramina, and the anatomical properties of the foramina are crucial in clinical interventions. The purpose of the current study is to evaluate possible asymmetries regarding the middle and posterior cranial fossae foramina using 3D reconstructions of high-resolution computed tomography (CT) images. Patients and Methods: High-resolution cranial CT images of 253 female and 287 male adult patients were used in the study. The patients were 18 to 40 years of age without any apparent cranial pathology. The distances from the foramen rotundum, foramen ovale, foramen spinosum, internal acoustic meatus, hypoglossal canal to the midline were measured bilaterally to compare both sides. Results: The foramen spinosum and the mid-clival line measurements demonstrated statistically significant results favoring the right side (p=0.03, right mean 3.052 ± 0.253 cm, left mean 2.982 ± 0.193 cm). In males, the right foramen spinosum to mid-clival line measurements were significantly longer than the left side (p=0.027, right mean 3.150 ± 0.250 cm, left mean 3.070 ± 0.180 cm). Conclusion: As predicted, the male measurements were significantly longer than the female measurements regardless of sides in all measurements. The measurements of cranial asymmetries may help describe anomalies and may contribute to the clinical approachesPublication Open Access Menopoz Semptomlarını Değerlendirme Ölçeği (MSDÖ), Kupperman Menopoz Ölçeği (KMÖ) ve Nothingam Sağlık Profili (NSP) ölçeklerinin güvenilirlik ve yanıtlama etki büyüklüklerinin yeni menopozlu hastalarda karşılaştırılması(2008-06-01) BEKİROĞLU, GÜLNAZ NURAL; Bekiroğlu G.

Ö. , Özçelik S., Küçüktepe C., Bekiroğlu G. N. , Akyüz S.Purpose: This study explores the effectiveness of a comprehensive structured teaching model – the “PaFein” – for instructing postgraduate pediatric dental residents in the provision of pain-free local anesthesia to children. Methods: Ten postgraduate pediatric dental residents and 172 children between the ages 5 and 13 participated in the study following ethical approval. The previously measured baselines guided the randomization of study and control groups. The study group (five residents) attended the PaFein course (9 hours). Based on power calculations, residents performed dental injections (8 mandibular block, 8 palatal/lingual and 14 buccal infiltrations) in randomly assigned child patients. Demographic data of residents/children, parental and self-report anxiety scores and Visual Analogue Scale (VAS) pain scores were noted to examine children’s anxiety and pain during dental injections. Results: Children’s mean anxiety score did not differ significantly between groups; however, VAS pain reports during dental injections (a, b, c, d) were found lower in the PaFein study group than the control group (p < 0.05). VAS pain reports for (a) buccal injections were 1.08 and 1.9 (p = 0.02); (b) inferior alveolar nerve blocks were 1.58 and 3.37 (p = 0.0002); (c) palatal/lingual injections were 1.34 and 3.02 (p < 0.0001); (d) total means were 1.28 and 2.59, respectively (p = 0.0001). VAS pain reports of anxious and non-anxious children in the PaFein study group (1.63 and 1.17) were also lower than the control group (3.33 and 2.39) (p < 0.0001 and p = 0.005). Conclusion: The “PaFein” teaching model was found to be effective in training dental residents to reduce dental injection pain in children, including the anxious ones.
