Methods: D-SPIRIT is the first national, multicenter, prospective, observational, postmarketing registry that investigates the usage of dabigatran in real life. A total of 326 noveloral anticoagulant-eligible patients with atrial fibrillation who have been taking dabigatran etexilate therapy for stroke prevention at least 6 months from 9 different centers were enrolled into the registry. Patients were followed up for 2 years to evaluate the effectiveness and safety of the treatment. All adverse clinical events including bleeding, thromboembolic events, stroke, systemic embolism, transient ischemic attack, myocardial infarction, and all-cause death were recorded. Results: The mean age was 71.1 +/- 9.6 years, and 57.4% of the study participants were female. The mean CHA(2)DS(2)-VASc (congestive heart failure, hypertension, age >= 75 years, diabetes mellitus, stroke or transient ischemic attack [TIA], vascular disease, age 65-74 years, sex category) score was 3.4 +/- 1.6. The cumulative adverse clinical events rate was 6.30% per year. The rate for embolic events including TIA, ischemic stroke, and peripheral embolism was 1.26% per year. The rate for major bleeding was 2.20% per year, and the mortality rate was 0.94% per year. Conclusion: This registry obtained an important overview of the current safety and effectiveness of the dabigatran etexilate in Turkey. Our results indicate similar rates of thromboembolic and bleeding events with pivotal phase 3 trial and other real-life registries. However, rate of undertreatment usage of dabigatran etexilate in real life was found to be considerable.Item Turkish Contribution to Journal of Neurosurgery and Acta Neurochirurgica(2017) Altinors, Nur; Comert, Serhat; Sonmez, Erkin; Altinel, Faruk; 0000-0002-5693-3542; 0000-0002-8326-3900; 27593822; AAI-8820-2021; AAJ-5382-2021AIM: To evaluate the contribution of Turkish scientists to four journals published by Journal of Neurosurgery (JNS) Publishing Group and to Acta Neurochirurgica (AN) and to its Supplement (ANS). MATERIAL AND METHODS: We reviewed every issue of those journals to December 2015 for the total number of articles, articles produced from studies performed entirely in Turkey, and for publications overseas co-authored by the Turkish scientists using the websites of these journals. Citations were searched using "Web of Science" and "Google Scholar" databases. RESULTS: The total number of articles published was 19822 for JNS, 3227 for JNS Spine, 2526 for JNS Pediatrics and 2997 for Neurosurgical Focus. Turkish contribution was 556 articles. 337 (60.61%) articles were the products of studies performed entirely in Turkey, while 219 (39.38%) articles came from overseas, co-authored by Turkish scientists. Overall contribution was 1.94%. A total of 6469 articles were published in AN. 340 papers were the products of studies performed entirely in Turkey. Turkish scientists working overseas co-authored 37 articles. Total contribution was 377 articles (5.82%). 4134 papers had been published in ANS. Contribution was 69 articles (1.66%). CONCLUSION: Turkish contribution to these journals has started late. The gap has been compensated with publications in the last two decades. Manuscripts of higher scientific level with greater number of citations are needed to increase Turkish contribution to such journals.Item Burnout Syndrome Among Physicians: The Role of Socio-Demographic Characteristics(2017) Ozkula, Guler; Durukan, Elif; 0000-0002-8579-5564; AAJ-8621-2021Objective: Burnout is a syndrome that occurs in occupational groups, which are in close relation with people and includes dimensions of; emotional exhaustion, depersonalization and low sense of personal accomplishment. The aim of the present study is to investigate the relationship between socio-demographic characteristics and burnout syndrome in academic personel working at a hospital of Faculty of Medicine. Method: 258 physicians working at Baskent University Ankara Hospital have been included in the present study voluntarily, between January - April 2014 and they have been administered Socio-Demographic Data Form and Maslach Burnout Inventory. Results: Age, academic title, time span in the profession and at the institution, the number of patients daily examined, administrative tasks, receiving research supports, the number of lectures given were related to all dimensions of burnout: emotional exhaustion, depersonalization, and personal accomplishment. Personnel assignment, the number of monthly shifts, daily duration of work were related to emotional exhaustion and depersonalization. Specialty preferences and intention to continue on the profession were associated with emotional exhaustion and personal accomplishment. Personnel assignment criteria and time reserved for academic study were related to only emotional exhaustion whereas accessibility to scientific literature was linked to personal accomplishment. Conclusion: Older age, having an academic title, longer time span in the profession and at the institution, concidering the long term consequences of specialty selection are all individual factors that can be related to burnout syndrome. Developing health policies for an optimal organization of daily work duration, number of patients daily examined and personnel assignment criteria could prevent burnout. Also developing organizational climate to create time for academic study, supporting researches, increasing accessibility to scientific literature and optimization of education seminars in academic physicians could protect them from burnout syndrome. Prospective studies modeling individual and organizational risk factors for burnout on academic physicians will help to further illuminate the measures to protect physicians from burnout syndrome and also contribute to the enhancement of treatment service quality and foster the contribution to academic arena.Item An Extremely Rare Kidney Tumor: Primary Intraparenchymal Squamous Cell Carcinoma(2017) Ipekci, Tumay; Yuksel, Mustafa; Yildiz, Ali; Inal, Gulsah; Ipekci, Oncel; 0000-0002-2755-0526; AAB-2986-2020Primary squamous cell carcinoma of the renal parenchyma is a rare entity and only 4 cases have been reported in the literature. A 73-year-old female patient presented to our clinic with the complaint of right flank pain. On radiologic evaluation, a 6x5x4 cm hypodense mass showing heterogeneous contrast enhancement was observed in the upper pole of the right kidney. An uneventful laparoscopic radical nephrectomy was performed. Final pathologic diagnosis was squamous cell carcinoma. No pathological involvement was observed on postoperative positron emission tomography/ computed tomography. Our patient is still alive and she has not received any adjuvant treatment.Item Posttraumatic Stress Symptoms and Related Variables in Families of Children with Disabilities(2017) Olgunsoylu, Burcu; Gul, Seray Olcay; Ardic, Avsar; Unal, YesimThe purpose of this study was to examine the effects and relationships of variables related to the children with disabilities and their parents as well as the diagnosis process and informing parents after the diagnosis and variables which might be related to the traumatic stress levels of the parents of children with disabilities on parents' traumatic stress levels. This study which was conducted as relational research included a total of 347 parents of children with disabilities. Data collection forms included personal information form, Traumatic Stress Symptom Scale, and Multidimensional Scale of Perceived Social Support. The results showed that traumatic stress levels of parents of children with physical impairments were higher than other parents, there was a significant relationship between the time passed after the diagnosis and parents' traumatic stress levels; there was significant relationship between the parents' age and parents's traumatic stress levels; parents' traumatic stress levels didn't differ in terms of gender; traumatic stress levels of single parents were higher than married parents.Item Obese patients require higher, but not high pneumatic tourniquet inflation pressures using a novel technique during total knee arthroplasty(2018) Tuncali, Bahatin; Boya, Hakan; Kayhan, Zeynep; Arac, Sukru; 0000-0003-0579-1115; 0000-0002-7898-2943; 0000-0001-6110-4004; 29526158; AAJ-4623-2021; AAJ-7840-2021; AAJ-7840-2021Objectives: This study aims to investigate the effect of obesity on pneumatic tourniquet inflation pressures determined with a novel formula during total knee arthroplasty (TKA). Patients and methods: Data of 208 patients (19 males, 199 females; mean age 69.8 years; range, 53 to 84 years) who were performed TKA between January 2013 and December 2016 were evaluated prospectively. Patients were divided into two groups as non-obese (body mass index [BMI] <= 30.0 kg/m(2)) and obese (BMI > 30.0 kg/m(2)) according to BMI. Tourniquet inflation pressures were set using arterial occlusion pressure (AOP) estimation method and adding 20 mmHg of safety margin to AOP value. All patients were assessed intra-and postoperatively with outcome measures such as systolic blood pressure, AOP, tourniquet pressure and its effectiveness. The quality of the surgical field and complications were assessed by the surgical team in a blinded fashion. Results: The study included 118 and 90 lower extremity operations in obese and non-obese groups, respectively. Compared to non-obese group; extremity circumference, initial and maximal systolic blood pressures, AOP values, initial and maximal tourniquet pressures were higher in obese group. The performance of the tourniquet was assessed as "excellent" and "good" at almost all stages of the surgical procedure in all patients in both groups. No complication occurred intra-or postoperatively. Conclusion: Compared to non-obese patients, higher tourniquet inflation pressure is required in obese patients during TKA due to their wider extremity circumference and higher systolic blood pressure profile.
