Item Treatment Outcomes of Breast Cancer Liver Metastasis Treated with Stereotactic Body Radiotherapy(2018) Onal, Cem; Guler, Ozan Cem; Yildirim, Berna Akkus; https://orcid.org/0000-0002-2742-9021; https://orcid.org/0000-0001-6908-3412; https://orcid.org/0000-0001-6661-4185; 30296648; HOC-5611-2023; AAC-5654-2020; V-5717-2017Background: To assess the outcomes of breast cancer liver metastasis (BCLM) treated with stereotactic body radiotherapy (SBRT) and systemic treatment. Materials and methods: Patients with oligometastasis at the time of liver metastasis (LM) or who became oligometastatic (<= 5 metastases) after systemic treatment were assessed. Twenty-nine liver metastatic lesions were treated with a total of 54 Gy delivered in 3 fractions. The local control (LC), overall survival (OS), and progression-free survival (PFS) rates were calculated using Kaplan-Meier analyses. Results: A total of 22 patients with 29 liver metastatic lesions treated with liver SBRT between April 2013 and September 2017 were retrospectively analyzed. After a median follow-up time of 16.0 months (range 4.4-59.4 months), 18 patients (82%) had disease recurrence, median of 7.4 months (range 1.0-27.9 months) after completion of liver SBRT. The 1- and 2-year OS rates were 85% and 57%, and the 1- and 2-year PFS rates were 38% and 8%, respectively. The 1- and 2-year LC rates were 100% and 88%, respectively. No significant prognostic factors, including disease extension, size of metastasis, number of liver metastasis and timing of liver metastasis, hormonal status affecting OS, PFS and LC were found. No patients experienced Grade 4 or 5 toxicity; furthermore, only one patient experienced rib fracture 6 months after completion of treatment, and one patient had a duodenal ulcer. Conclusion: This study is the first to evaluate the feasibility of SBRT to BCLM patients. Liver SBRT is a conservative approach with excellent LC and limited toxicities. (C) 2018 Elsevier Ltd.

These were sometimes the sorcerers, herbalists, embers, enchanters, atasaguns or shamans of the period, and sometimes the physicians who worked on modern medicine of the period. Anatolia, as the land where civilizations intersect, contains traces of many cultures and has a very deep structure in terms of cultural accumulation. Considering ancient medicine in Anatolia, it can be seen that sometimes modern medical knowledge and traditional folk medicine methods are used together. These methods are frequently mentioned in written texts and many works in the field of health, both in copyright and translation, have been created. The fact that they include easy treatment methods for illnesses and that they contain medical information that the public can use in daily life emphasize the importance of such texts. It is known that the oldest medical texts in Turkish written in Anatolia were created in the 14th century. Since then, many works including field information such as medicine, folk medicine, pharmacology, botany have a special importance in terms of fully revealing the vocabulary and structure of our language. The text, which is our subject of study, is registered in the collection of Ankara National Library Elazig Provincial Public Library with the number 23 Hk 2/3. The title of the work appears to be Manzume-i Tib and its author Ferdi. The text, written in "me fa' i lun me fa' i lun fe' u lun" prosody pattern and consists of 61 couplets. Although the name of the author appears as Ferdi in the manuscript, the note that the author is not known was written at the beginning of the work. Although the year of writing is not known, the text was written in Old Anatolian Turkish. The note to the head of the manuscript contains the information that it contains some information about health protection. In its content, factors affecting health and disease are emphasized. The medical knowledge until the time of writing and some practices from the field of folk medicine have been combined to include behaviors that should be done in the treatment of diseases and avoided for some diseases. Writing a text on the subject of medicine with prosody, besides the purpose of informing, it also ensures the permanence of the information transferred in a certain harmony. In the text, on the subject of diseases; Problems such as indigestion, headache, sore throat or dry throat, weakness, paralysis, sciatica, meningitis, constipation, hemorrhoids, cramps and pain were included. Among the treatments; Methods such as vomiting, laxative, cupping, and consent have been discussed. Although in small numbers, there are herbal preparations that can be used for some ailments such as tooth jaundice and bad breath. In the face of some ailments and conditions, the daily foods recommended for therapeutic purposes have been pointed out. It is seen that information about mood is also included in addition to physical health. In our study, by giving the transcription of the aforementioned manuscript, it will be pointed out the diseases, diseases and the treatment methods recommended for them. These suggestions will be examined under the headings of beneficial and harmful actions. Comparisons will be made by giving examples from other medical texts written in Anatolia. At the end of the review, there will be a glossary of terms used in the fields of medicine and folk medicine. With further examination of such texts, Old Anatolian Turkish vocabulary will be put forward in a healthier way and data that shed light on various fields such as botany, folklore, pharmacology and psychology will be obtained along with medicine.Item Evaluation of the Knowledge Level, Practice and Attitudes of the Caregivers on Ketogenic Diet Management(2022) Bayram, Sinem; Caliskan, HilalObjective: Patients with intractable childhood epilepsy may benefit from ketogenic diet treatment. Management of ketogenic diet depends on the knowledge level and practice and attitudes of their caregivers. Although advances have been made on early diagnosis and treatment options, there is still a lack of knowledge in children with epilepsy and their caregivers. Methods: In the study, 40 voluntary individuals caring for a child with intractable childhood epilepsy who is under a ketogenic diet were included. The visual analog scale was used to determine adherence to the ketogenic diet for both caregivers and children. Dietary adherence of young children (<10 years) was assessed by the caregiver. Ketogenic diet knowledge of caregivers was determined to form with 40 questions (free/prohibited foods, meal contents, any form of carbohydrate sources, label reading, side effect awareness, and management practices). Results: Availability of ketogenic products, feeling of hunger, frequent glucose, and ketone measurement were determined to be the most difficulties in adherence to the ketogenic diet. According to the visual analog scale results, the mean knowledge level of the caregivers was 3.55 +/- 3.67, ketogenic diet adherence was 7.52 +/- 2.40 for the caregivers, and 8.42 +/- 1.62 for the patients. 25% of the caregivers have high, 65% of them have low knowledge. The number of antiepileptic drugs used decreased. The number of seizures per week was 32.65 +/- 21.15 before the ketogenic diet, it decreased to 21.54 +/- 15.69. Conclusions: The effectiveness of the ketogenic diet was better in medium and high knowledge levels. As the competence increases, ketogenic diet management will be easier. Therefore, it would be beneficial to visit a dietitian during clinic visits and to seek answers to food-related problems.Item Reporting quality of animal studies published in journals listed in ULAKBIM TR index: a systematic review on compliance to the ARRIVE guidelines(2022) Aydingoz, Selda Emre; Efe, Oguzhan Ekin; Caliskan, Gokce; 0000-0001-7823-7620; 0000-0002-3243-7843; ABA-4291-2020; W-7908-2019Transparent reporting of animal studies is key to ensure reproducibility. The primary guideline for reporting animal studies is the ARRIVE (Animal Research: Reporting of In Vivo Experiments). We aimed to evaluate the compliance to the updated ARRIVE guidelines (version 2.0, date 2020) in animal studies published in journals indexed by the Turkish Academic Network and Information Centre (ULAKBIM TR Index). This was a retrospective analysis of reporting quality of animal studies published in journals listed in ULAKBIM TR Index between January 2010 and August 2021. The percentage of articles that fully reported each " of the ARRIVE Essential 10: Compliance Questionnaire was calculated, and effects of journal- and article-related factors were evaluated. Totally, 235 articles published in 89 journals were included into the analysis. The mean percentage of fully reported items was 59.1%+/- 10.9%, the least reported items being those related with bias - "blinding", "allocation to study groups", "assessment of statistical assumptions", "excluded animals", and "sample size calculation" (0.9%-10.6%). The journal's publisher, frequency, language, being indexed in the Science Citation Index Expanded, and the ratio of animal studies had no significant effect on this percentage (p>0.05). However, journals supporting the ARRIVE guidelines had significantly and higher compliance (62.1 %+/- 10.1% vs. 58.2%+/- 11.0% for supporters and non-supporters, respectively; p=0.017, 95%CI -7.0 to-0.7). Articles published after 2015 had higher compliance to the ARRIVE guidelines than those published previously (60.9%+/- 10.4% vs. 57.9%+/- 11.1%, respectively; p=0.037, 95%CI -5.8 to -0.2). Although progress has been made, compliance to the ARRIVE guidelines is still low in animal studies published in journals listed in ULAKBIM TR Index-Turkey's scientific journal database that covers over 800 peer-review journals. In order to increase the reporting quality and reproducibility of animal studies, it is imperative to raise awareness among researchers and journals, and to enforce the ARRIVE guidelines in editorial policy of journals.Item Small genus-4 Lefschetz fibrations on simply-connected 4-manifolds(2022) Altunoz, TulinWe consider simply connected 4-manifolds admitting Lefschetz fibrations over the 2-sphere. We explicitly construct nonhyperelliptic and hyperelliptic Lefschetz fibrations of genus 4 on simply-connected 4-manifolds which are exotic symplectic 4-manifolds in the homeomorphism classes of CP2 #8<(CP2)over bar> and CP2#9<(CP2)over bar>, respectively. From these, we provide upper bounds for the minimal number of singular fibers of such fibrations. In addition, we prove that this number is equal to 18 for g = 3 when such fibrations are hyperelliptic. Moreover, we discuss these numbers for higher genera.Item Arf numerical semigroups with multiplicity 11 and 13(2022) Karakas, Halil Ibrahim; Ilhan, Sedat; Suer, Meral; AAY-4394-2021Item P-Strong Convergence With Respect To An Orlicz Function(2022) Sahin Bayram, Nilay; GPT-3667-2022The concepts of strong convergence, statistical convergence, and uniform integrability are of some interest in convergence theories. Recently unver and Orhan [19] have introduced the concepts of P-strong and P-statistical convergences with the help of power series methods and established a relationship between them. In the present paper, we introduce the notion of P-strong convergence with respect to an Orlicz function and prove that all these three concepts are boundedly equivalent provided that Orlicz function satisfies o2- condition. We also get an improvement of this result by using the concept of uniform integrability.Item Use Of Deep Learning Methods For Hand Fracture Detection From Plain Hand Radiographs(2022) Ureten, Kemal; Sevinc, Huseyin Fatih; Igdeli, Ufuk; Onay, Aslihan; Maras, Yuksel; https://orcid.org/0000-0003-4213-9126; 35099027BACKGROUND: Patients with hand trauma are usually examined in emergency departments of hospitals. Hand fractures are frequently observed in patients with hand trauma. Here, we aim to develop a computer-aided diagnosis (CAD) method to assist physicians in the diagnosis of hand fractures using deep learning methods. METHODS: In this study, Convolutional Neural Networks (CNN) were used and the transfer learning method was applied. There were 275 fractured wrists, 257 fractured phalanx, and 270 normal hand radiographs in the raw dataset. CNN, a deep learning method, were used in this study. In order to increase the performance of the model, transfer learning was applied with the pre-trained VGG-16, GoogLeNet, and ResNet-50 networks. RESULTS: The accuracy, sensitivity, specificity, and precision results in Group 1 (wrist fracture and normal hand) dataset were 93.3%, 96.8%, 90.3%, and 89.7% , respectively, with VGG-16, were 88.9%, 94.9%, 84.2%, and 82.4%, respectively, with Resnet-50, and were 88.1%, 90.6%, 85.9%, and 85.3%, respectively, with GoogLeNet. The accuracy, sensitivity, specificity, and precision results in Group 2 (phalanx fracture and normal hand) dataset were 84.0%, 84.1%, 83.8%, and 82.8%, respectively, with VGG-16, were 79.4%, 78.5%, 80.3%, and 79.7%, respectively, with Resnet-50, and were 81.7%, 81.3%, 82.1%, and 81.3%, respectively, with GoogLeNet. CONCLUSION: We achieved promising results in this CAD method, which we developed by applying methods such as transfer learning, data augmentation, which are state-of-the-art practices in deep learning applications. This CAD method can assist physicians working in the emergency departments of small hospitals when interpreting hand radiographs, especially when it is difficult to reach qualified colleagues, such as night shifts and weekends.Item Evaluation Of Demographic And Clinical Characteristics Of Female Patients Presenting With MINOCA And Differences Between Male Patients: A Subgroup Analysis Of MINOCA-TR Registry(2022) Gok, Gulay; Coner, Ali; Cinar, Tufan; Kilic, Salih; Yenercag, Mustafa; Oz, Ahmet; Ekmekci, Cenk; Ozluk, Ozlem; Zoghi, Mehdi; Ergene, Asim Oktay; Turk, Ugur Onsel; 35197228Objective: Although the prevalence and rate of myocardial infarction with non-obstructive coronary arteries (MINOCA) are higher in women than in men in previous cohorts, potential demographic and clinical differences between women who are diagnosed with MINOCA versus myocardial infarction with obstructive coronary arteries (MIOCA) have not been studied till date. In this study, we aimed to document these characteristics and to compare them between female patients with MINOCA and MIOCA. Methods: The study was a subgroup analysis of the MINO-CA-TR study. The study was a multi-center, observational cohort study that was conducted in Turkey between March 2018 and October 2018. In this study, 477 (29.3%) female patients who had been diagnosed with acute myocardial infarction were evaluated. Results: Of these women, 49 (10.3%) were diagnosed with MINOCA (mean age 58.9 +/- 12.9 years) and 428 (89.7%) had a final diagnosis of MIOCA (mean age 67.4 +/- 11.8 years). The prevalence of hypertension, hyperlipidemia, and diabetes mellitus was significantly lower in the MINOCA group than in the MIOCA group. In addition, the MINOCA group had higher rates of recent flu history and non-ST elevation myocardial infarction (NSTEMI) presentation than the MIOCA group. There were significant clinical differences in patients with MINOCA in terms of sex. The female patients were older, had higher systolic blood pressures, and lower hemoglobin levels than male patients. Conclusion: The study revealed that the prevalence of traditional coronary artery disease risk factors was lower in female patients with MINOCA than in those who had final diagnosis of MIOCA.Item Improvement of Work Productivity and Quality of Life with Anti-Tumor Necrosis Factor Treatment Used in Crohn's Disease in Routine Clinical Practice in Turkey(2022) Toruner, Murat; Basaranoglu, Metin; Atug, Ozlen; Senturk, Omer; Akyuz, Filiz; Cekic, Cem; Hamzaoglu, Hulya Over; Tekin, Fatih; Sezgin, Orhan; Akpinar, Hale; Celik, Aykut Ferhat; Tezel, Ahmet; Gokturk, Huseyin Savas; Kav, Taylan; 35678798Background: Patients with Crohn's disease experience major deterioration in work productivity and quality of life. We aimed to provide the long-term effects of anti-tumor necrosis factor agents on work productivity and activity impairment and quality of life in patients with Crohn's disease using the Inflammatory Bowel Disease Questionnaire and the Short-Form Health Survey-36. Methods: Patients with Crohn's disease and initiated an anti-tumor necrosis factor treatment were included and followed up for 12 months in this observational study. Results: A total of 106 patients were included in this study, and 64.2% of the patients were males. Mean [+/- standard deviation] age was 36.8 [+/- 10.9] years. At baseline, mostly perianal fistulas [65.7%] were observed [n = 23]. Intestinal stenosis was detected in 34.9% of the patients [n = 37], and most of the stenosis was located in the ileum [70.6%] followed by the colon [20.6%]. Extraintestinal symptoms were observed in 24 patients [22.6%]. Most frequent extraintestinal symptom was arthritis with 71.4% [n = 15]. Mean time from first symptom to initiation of anti-tumor necrosis factor treatment was 6.3 [+/- 5.0] years. Improvements in work productivity and activity impairment scores throughout 12 months were -24.1% [P =.003] for work time missed, -18.0% [P =.006] for impairment at work, -8.5% [P =.160] for overall work impairment, and -17.0% [P <.001] for daily activity impairment. Similarly, significant improvements [P <.001] were detected in all components of the Inflammatory Bowel Disease Questionnaire when compared to baseline. Statistically significant improvements [P <.05] were detected for all components of Short-Form Health Survey-36 except for mental health [P =.095]. Conclusion: Our study indicates the significant improvement in work productivity and activity impairment and quality of life of patients with Crohn's disease who receive long-term anti-tumor necrosis factor treatment.
