Item A Bibliometric Analysis of Turkey's Contribution to Bone Health Literature from an Endocrinologist Perspective(2019) Degertekin, Ceyla Konca; İyidir, Ozlem Turhan; Yavuz, Dilek Gogas; 0000-0001-5305-6807; K-7904-2019Objective: To analyze the trend of Turkish publications related to bone health with respect to global publications and to determine the relative contribution of endocrinologists to metabolic bone disease literature. Material and Methods: Publications related to bone health up to and including the year 2017 were retrieved from the "Web of Science" (WoS) and "TUrkiye Atif Dizini" (TAD) database using metabolic bone disease related MeSH terms. Excel (v15.30) and Endnote X8 were used to summarize the bibliometric features, including the number of publications, authors, their affiliations, and contributing countries. Keywords were divided, for a detailed analysis, into three clusters: osteoporosis, parathyroid, and vitamin D-related. Results: A total of 1.880.666 papers were retrieved from WoS globally and, of those, 21.165 (1.13%) were published from Turkey. Of the papers published from Turkey, 3.0% were primarily contributed by endocrinologists. The relative contribution of endocrinology to osteoporosis-related (4.6% vs. 1.5%), parathyroid-related (23.7% vs. 5.3%), and vitamin D-related (23.7% vs. 5.3%) publications was higher for articles originating from Turkey compared to the global data. Endocrinology was among the top five specialties contributing to Turkish metabolic bone disease literature indexed in WoS and TAD. Conclusion: Turkey has a less than expected rate of research output in terms of metabolic bone disease. The relatively higher contribution of endocrinology to that effort is promising. Supporting bone research might accelerate the efforts of Turkish researchers in the field of metabolic bone health.Item Population-based assessment of gastrointestinal symptoms and diseases: Cappadocia Cohort, Turkey(2019) Sezgin, Orhan; Akpinar, Hale; Ozer, Birol; Toruner, Murat; Bal, Kadir; Bor, Serhat; 31854305Background/Aims: The aim of this study was to determine the prevalence of symptoms and diseases of the lower and upper gastrointestinal system (GIS) in a population-based sample. Materials and Methods: The cross-sectional cohort study was conducted in Cappadocia cohort comprising the Gulsehir and Avanos districts. The "Gastrointestinal Symptom Questionnaire" was applied to persons over the age of 18 years. Results: The GI Symptom Questionnaire was applied to 3369 subjects, and height and body weight were measured in 2797 consenting subjects. Of the participants, 61% were female and the mean patient age was 50 +/- 15 years. At least one GI symptom was present in 70.6% of the cohort. The most common upper GI symptoms were gastric bloating (31.0%) and heartburn (29.1%). The most common lower GI symptom was abnormal defecation (33.5). The prevalence of upper GIS and lower GIS diseases was 32.7% and 12.9%, respectively, and the prevalence of togetherness of upper and lower GIS diseases was 9.9%. Prevalence of GIS disease was approximately 3 times higher in females (p<0.001). All of the upper and lower GI symptoms and the prevalence of upper GIS disease increased in line with Body mass index (BMI). Conclusion: This first population-based, cross-sectional cohort study revealed that the prevalence of GIS diseases is critically high for optimal public health. Special attention must be paid to these diseases while planning health policies and reimbursements.Item A View from Young Oncologists on Clinical Trials in Turkey: Obstacles and Solution Proposals(2014) Akman, Tulay; Tanriverdi, Ozgur; Ozturk, Mehmet A.; Petekkaya, Ibrahim; Bakkal, Hakan; Sonmez, Ozlem U.; Avci, Nilufer; Zengin, Seyda; Aksu, Gorkem; Ozyigit, Gokhan; Akbali, HuseyinThere is a new improvement in oncology nearly in every day as a result of preclinical or clinical. As the number of publication per capita, Turkey is far behind the other developed European countries. For example, the number of publications in oncology field is 2.134.964 in the world, it is 15.576 in our country. The most important obstacles for clinical trials in Turkey may be listed as financial problems, difficulties of working conditions, time limitation due to work intensity, inadequate experienced/trained man-power, absence of assistance team at all steps of a scientific trial, difficulties faced during project planning and ethics committee submissions, and lack of motivation. In this article, we, as young oncologists, aimed to discuss the place of Turkey in areas of scientific and clinical trials in the world; underlying causes for inadequate number, type and quality of national studies and possible solution proposals in our country.Item Problematic Areas Related to Sexual Life of Individuals with Gynecological Cancer: A qualitative Study in Turkey(2015) Pinar, Gul; Pinar, Tevfik; Akalin, Ayse; Saydam, Tulay; Ayhan, AliThis study was conducted to examine problematic areas related to sexual life of individuals with gynecological cancer. Qualitative phenomenological research design was used in the study. The data were collected through "Semistructured In-depth Interview Form" and "Individual Information Form" with 30 women diagnosed with gynecological cancer. In-depth interview technique was used for obtaining data related to sexual problem areas of women. The data obtained were evaluated by content analysis. Average age of women who participated in the study was 46.70 +/- 10.66 (min=30, max=67), and women who were followed for the diagnosis of endometrium cancer (53.3%), ovarian cancer (36.7%), cervical cancer (10%). It was determined that there were significant changes in sexual lives of the individuals following the illness, and that body image, role of sexuality, sexual functions and reproduction ability, which are the four important components of sexual health, were affected unfavorably to a great extent. It was determined in this study that individuals with gynecological cancer face multidimensional problems regarding sexual life. Adoption of holistic approach by health professionals in the evaluation of sexual problems of women and attempting to solve the problem are of significance.Item Design and rationale of dabigatran's stroke prevention in real life in Turkey (D-SPIRIT)(2016) Turk, Ugur Onsel; Alioglu, Emin; Tuncer, Esref; Ozpelit, Mehmet Emre; Pekel, Nihat; Tengiz, Istemihan; Cetin, Nurullah; Dalgic, Onur; Topaloglu, Caner; Bilgin, Nazile; Altin, Cihan; Ozdemirkiran, Tolga; Tuluce, Kamil; Turkoglu, Ebru Ipek; Ozpelit, Ebru; 27138311Objective: The D-SPIRIT registry is designed to investigate the safety and efficacy of dabigatran etexilate in patients with nonvalvular atrial fibrillation (NVAF) and to collect data on outcomes in clinical practice. Methods: The D-SPIRIT is a national, prospective, observational, post-marketing registry involving patients with NVAF who have been taking dabigatran etexilate therapy for stroke prevention for a minimum of 6 months prior to enrollment. The registry will collect and analyze data from routine care, enrolling up to 600 patients in 9 centers. Patients will be followed up for 2 years to evaluate effectiveness and safety. A sample size of 600 subjects is proposed based on the following assumptions; Two-sided significance level of 0.05 (1-sided significance level of 0.025), ischemic stroke incidence rate of 0.768%-1.111%, hemorrhagic stroke incidence rate of 0.109%-0.130%, transient ischemic attack incidence rate of 0.722%-0.623%, therapy discontinuation incidence rate of 40% at day 730, and duration of enrollment period of 12 months with non-uniformed enrollment rate. Ethics approval was given by Dokuz Eyll University Ethics Committee of Clinical Research (2014/54) and approved by the Turkish Ministry of Health. Conclusion: Potential results of D-SPIRIT registry will add data from clinical practice to those from the RE-LY trial to expand knowledge of dabigatran etexilate treatment in patients with NVAF.Item What does the Data of 354,725 Patients from Turkey Tell Us About Cervical Smear Epithelial Cell Abnormalities? - The Epithelial Cell Abnormality Rate is Increasing - Quality Control Studies and Corrective Activity are Musts(2017) Bolat, Filiz; Haberal, Nihan; 0000-0001-9852-9911; 28272675; AAK-4587-2021Objective: There is no other screening program close to the success rate of PAP test. Cervical cytology constitutes a large workload so that quality control in cervical cytology is important for the quality assurance of pathology laboratories. Material and Method: In this study, we collected the cervical cytology results from all over Turkey and discussed the parameters influencing the quality of the PAP test. The study was conducted with Turkish gynaecopathology working group and 38 centers (totally 45 hospitals) agreed to contribute from 24 different cities. The study was designed to cover the cervical cytology results during 2013. The results were evaluated from the data based on an online questionnaire. Results: The total number of Epithelial Cell Abnormality was 18,020 and the global Epithelial Cell Abnormality rate was 5.08% in the total 354,725 smears and ranging between 0.3% to 16.64% among centers. The Atypical squamous cells/Squamous intraepithelial lesion ratios changed within the range of 0.21-13.94 with an average of 2.61. When the centers were asked whether they performed quality assurance studies, only 14 out of 28 centers, which shared the information, had such a control study and some quality parameters were better in these centers. Conclusion: There is an increase in the global Epithelial Cell Abnormality rate and there are great differences among centers. Quality control studies including the Atypical squamous cells/Squamous intraepithelial lesion ratio are important. Corrective and preventive action according to quality control parameters is a must. A cervical cytology subspecialist in every center can be utopic but a dedicated pathologist in the center is certainly needed.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 Hybrid War and Its Strategic Implications to Turkey(2017) Bingol, Oktay; 0000-0002-4794-5656; AAA-5129-2020Discussions on the hybrid threats and hybrid wars have begun to gain interest among the security communities around the world since 2000s, and exponentially increased after Russian-Ukraine conflict in 2014. The political and military conflict between Russia and Turkey since November 2015 has carried the discussion to Turkey. Now it is believed that Turkey is in fact in a multi-front hybrid war with some of its neighbors but not just Russia. In this article it is aimed to fully explore hybrid war concept and its strategic implications to Turkey. The definitions of hybrid threat, hybrid conflict and hybrid war is considered in the first section. Then Russian hybrid war concept is discussed. Next, features and consequences of hybrid war are applied to Turkey in order to identify the strategic implications. Finally, recommendations are made as to a way ahead for Turkish decision makers with respect to fighting hybrid war.
