Item There Is No Doubt About The Winner Of The Lion-Rabbit Fight(2022) Onal, Cem; Oymak, Ezgi; Guler, Ozan C.; https://orcid.org/0000-0002-2742-9021; 35652580; D-5195-2014Item Recommendations for Ramadan Fasting to Patients with Cardiovascular Diseases; Turkish Society of Cardiology Consensus Report(2021) Alper, Ahmet Taha; Akboga, Mehmet Kadri; Ozcan, Kazim Serhan; Tengiz, Istemihan; Turk, Ugur Onsel; Yildiz, Mustafa; Yilmaz, Mehmet Birhan; Kayikcioglu, Meral; Gazi, Emine; Yildirir, Aylin; 33960303Item Survival impact of number of removed para-aortic lymph nodes in stage I epithelial ovarian cancer(2021) Gunakan, Emre; Akilli, Huseyin; Kara, Atacan Timucin; Altundag, Ozden; Haberal, Asuman Nihan; Meydanli, Mehmet Mutlu; Ayhan, Ali; 0000-0002-5240-8441; 0000-0003-0197-6622; 0000-0001-8854-8190; 34410474; AAX-3230-2020; W-9219-2019; ABI-1707-2020Purpose The survival effect of presence or absence of lymphadenectomy in early-stage epithelial ovarian cancer (EOC) was priorly shown but the effect of number of removed lymph nodes kept in background. We aimed to evaluate the survival impact of number of removed lymph nodes and their localizations in stage I EOC. Methods This study included 182 patients. The best cut-off levels for number of pelvic and para-aortic lymph nodes (PaLN) were 24 and 10, respectively. Univariate and multivariate survival analyses were performed for these cut-offs and other prognostic factors. Results The median age of the patients was 49. The median number of removed pelvic and paraartic lymph nodes were 29 and 9, respectively. The median overall (OS) and progression-free survival (PFS) were 67 and 50 months, respectively. The 5-year OS rate was 89.6%. Recurrence occured in 24 (19.5%) patients. In univariate analyses tumor grade (p: 0.005), pelvic LN number (p: 0.041) and PaLN number (p: 0.004) were the factors that were significantly associated with PFS. Tumor grade and PaLN number were independently and significantly associated with PFS in multivariate analyses (p: 0.015 and p: 0.017, respectively). In OS analyses, age, tumor grade, presence of LVI, number of pelvic and PaLNs were the significantly associated factors (p < 0.05 for all). In multivariate analyses, age and PaLN number were independently and significantly associated with OS (p: 0.011 and p: 0.021, respectively). Conclusions The number and localizations of removed lymph nodes may have a survival affect in stage I EOC. We also think that this study may constitute a kernel point for larger prospective series on lymph node number and lymphatic regions.Item Radiologic Outcomes and Complication Analysis of the Posterior Vertebral Column Resection in the Treatment of Previously Operated Severe Kyphoscoliosis: A Retrospective Case Series(2020) Atici, Yunus; Polat, Baris; Erdogan, Sinan; Carkci, Engin; Polat, Ayse Esin; Demiroz, Serdar; Benli, Ismet Teoman; 32194269Item Cerebral Venous Sinus Thrombosis in Women: Subgroup Analysis of the VENOST Study(2020) Goksel, Basak Karakurum; 0000-0003-2766-2277; 32953038; AAE-2609-2021Background. Early diagnosis of cerebral venous sinus thrombosis (CVST) associated with reproductive health-related risk factors (RHRF) including pregnancy, puerperium, and oral contraceptive (OC) use can prevent severe neurological sequelae; thus, the symptoms must be documented in detail for each group.Methods. Out of 1144 patients with CVST, a total of 777 women were enrolled from a multicenter for the study of cerebral venous sinus thrombosis (VENOST). Demographic, biochemical, clinical, and radiological aspects were compared for 324 cases with RHRF and 453 cases without RHRF.Results. The mean age of the RHRF (-) group (43.2 +/- 13 years) was significantly higher than of the RHRF (+) group (34 +/- 9years). A previous history of deep venous thrombosis (3%), isolated cavernous sinus involvement (1%), cranial neuropathy (13%), comorbid malignancy (7%), and its disability scores after 12 months (9%) were significantly higher in the RHRF (-) group. The RHRF (+) group consisted of 44% cases of puerperium, 33% cases of OC users and 23% of pregnant women. The mean age was found to be higher in OC users (38 +/- 9years). A previous history of deep venous thrombosis was slightly higher in the pregnancy subgroup (4%). Epileptic seizures were more common in the puerperium group (44%).Conclusion. The results of our study indicate that the risk of CSVT increases parallel to age, OC use, and puerperium period. In addition, when considering the frequency of findings and symptoms, epileptic seizures in the puerperium subgroup of the RHRF (+) group and malignancies in the RHRF (-) group may accompany the CSVT. In daily practice, predicting these risks for the CSVT and early recognition of the symptoms will provide significant benefits to patients.Item The effect of helicobacter pylori eradication on atrophic gastritis and intestinal metaplasia : a retrospective single center research(2020) Suna, N.; Etik, D.; Ocal, S.; Gunduz, C.; Acikgoz, A.; Bildik, I; Gursoy, A.; Kasgoz, I; Tuleylioglu, H.; Boyacioglu, A.; 0000-0003-3719-9482; 0000-0002-4724-0728; 0000-0001-6234-7788; 33094583; ABH-4817-2020; AAJ-4707-2021; AAI-8822-2021Background and study aims : Gastric cancer (GC) is one of the major causes of cancer-related deaths worldwide. Helicobacter pylori (Hp) plays an important role in gastric carcinogenesis by inducing precancerous changes such as atrophic gastritis (AG) and intestinal metaplasia (IM). In our study, we aim to compare the grade of AG and IM before and after Hp eradication in patients who underwent esophagogastroduodenoscopy (EGD) in our center. Patients and methods : The data of 40.060 patients who underwent EGD for various reasons in our Endoscopy Unit between June 2011 and November 2017 were retrospectively evaluated. The grade of AG and IM before and after Hp eradication of patients meeting the study criteria were compared with each other. In addition, these findings were compared using OLGA and OLGIM staging systems. Results : A total of 175 patients, 89 (50.9%) women and 86 (49.1%) men, were included in the study. The mean age was 55 +/- 12 years. The mean time between two EGD examinations was 38 +/- 14 months. Significant improvement was observed in the grade of AG on corpus and antrum after Hp eradication (P=0.000, P=0.008). In the corpus and antrum, the grade of IM was regressed but this was not significant (P=0.80 and P=0.370 respectively). There was a decrease in OLGA stages after Hp eradication (P=0.000). There was also a reduction in the OLGIM stages, but this was not significant(P=0.341). Conclusion: Our study demonstrates that Hp eradication may reduce the risk of developing GC by providing an improvement in AG and IM which are precancerous changes in GC.Item Platelet/lymphocyte ratio is an independent predictor for osteoporosis(2019) Eroglu, Semra; Karatas, Gulsah; 30957129; AAD-8353-2020Objectives: To investigate the intercourse between the platelet/lymphocyte (P/L) and neutrophil/lymphocyte ratio (N/L), and vitamin D (Vit-D) levels in low bone mineral density (BMD) of women. Methods: Two hundred fifty-two postmenopausal female outpatients who were admitted to the obstetrics and gynecology and physical therapy clinics between July 2016 and December 2017 were retrospectively analyzed. The patients were grouped in relation to their T-score (normal [n=92], osteopenia [n=112], and PMO [n=48]). The serum levels of P/L, N/L, Vit-D, BMD and complete blood count of the patients were retrospectively examined. Results: The median P/L was significantly higher and Vit-D levels were significantly lower in the PMO group (130.75 [52.89-385] versus 123.05 [54-232.5], p=0.02 and 15.4 [4-34] versus 20.1 [4-47], p=0.003). While BMD and P/L were negatively correlated, a positive correlation between BMD and Vit-D was found. Vitamin D levels were negatively correlated with P/L (p<0.001) and N/L (p=0.04). Older age (>= 65 years), Vit-D deficiency and P/L values >125.06 were found as independent prognostic factors for PMO in regression analysis. Conclusion: Higher P/L seems to be a quite simple marker to help predict postmenopausal PMO. As seen in our study, having low levels of Vit-D is crucial for PMO.Item Simultaneous integrated boost to intraprostatic lesions using different energy levels of intensity-modulated radiotherapy and volumetric-arc therapy(2014) Onal, C.; Sonmez, S.; Erbay, G.; Guler, O.C.; Arslan, G.Objective: This study compared the dosimetry of volumetric-arc therapy (VMAT) and intensity-modulated radiotherapy (IMRT) with a dynamic multileaf collimator using the Monte Carlo algorithm in the treatment of prostate cancer with and without simultaneous integrated boost (SIB) at different energy levels. Methods: The data of 15 biopsy-proven prostate cancer patients were evaluated. The prescribed dose was 78 Gy to the planning target volume (PTV78) including the prostate and seminal vesicles and 86 Gy (PTV86) in 39 fractions to the intraprostatic lesion, which was delineated by MRI or MR-spectroscopy. Results: PTV dose homogeneity was better for IMRT than VMAT at all energy levels for both PTV78 and PTV86. Lower rectum doses (V-30-V-50) were significantly higher with SIB compared with PTV78 plans in both IMRT and VMAT plans at all energy levels. The bladder doses at high dose level (V-60-V-80) Were significantly higher in IMRT plans with SIB at all energy levels compared with PTV78 plans, but no significant difference was Observed in VMAT plans. VMAT plans resulted in a significant decrease in the mean monitor units (MUs) for 6,10, and 15 MV energy levels both in plans with and those without SIB. Conclusion: Dose escalation to intraprostatic lesions with 86 Gy is safe without causing Serious increase in organs at risk (OARs) doses. VMAT is advantageous in sparing OARs and requiring less MU than IMRT. Advances in knowledge: VMAT with SIB to intraprostatic lesion is a feasible method in treating prostate cancer. Additionally, no dosimetric advantage of higher energy is observed.Item A clinical dilemma about a new oral anticoagulant treatment(2014) Altin, Cihan; Ozturkeri, Ovgu Anil; Gezmis, Esin; Muderrisoglu, Haldun; 25341482Item Value of diffusion-weighted imaging in hypoglycemic encephalopathy(2015) Donmez, Fuldem Y.; Arslan, Serdar; Agildere, Ahmed M.; Ecevit, Ayse; 26166602
