Objective: Breast cancer (BC) is the most frequent cancer among women. Many BC patients suffer from sleep problems, which have a negative impact on their quality of life (QoL). Our study aims to investigate sleep problems in BC patients treated with active chemotherapy or in remission in comparison with a healthy control group (HCG), given the importance of sleep disorders and QoL. Materials and Methods: A multicenter, cross-sectional study was conducted. Four different surveys including sociodemographic characteristics questionnaire, Pittsburgh sleep quality index (PSQI), hospital anxiety and depression scale and The European Organisation for Research and Treatment of Cancer core quality of life questionnaire (QLQ-C30) were used to collect study parameters. Results: Of 164 participants, the mean age was 42.0±11.7 years. Overall PSQI median score for all participants was 6 points (range, 3-9 points). PSQI median value was higher in cancer patients compared to the control group, which were 6 points (range, 4-9 points), and 4 points (range, 3-7 points), respectively (p=0.004). The mean depression score was 5 points (range, 3-8 points) in BC patients, and 4 points (range, 2-6 points) in HCGs, respectively (p=0.025). Having BC diagnosis was an independent factor increasing the risk of bad sleep quality in compared to healthy controls (odds ratio: 2.568, 95% confidence interval: 1.169-5.645; p=0.019). Conclusion: There was a close association between poor sleep quality, depression and QoL scores in patients with BC. In patients with breast cancer, appropriate management of associated comorbidities will aid a better quality of life in these patients. [ABSTRACT FROM AUTHOR]

In the last years, Fluent and OpenFoam are the two most reliable CFD software used in simulations of different flow fields in both academic and industry. In this study, the performance of these two CFD simulation software relative to each other was determined for the same boundary conditions for a selected flow area. The highlight of OpenFoam CFD software is that it is free software with open source. In this context, our primary goal is to lead the spread of open-source and free software in the implementation of engineering processes in our country. As the flow area, an airfoil with Naca 2415 section manufactured by Harran-Ravens team was selected for Teknofest competition. As a result of the simulations carried out, the aerodynamic forces and moments that affect the airfoil have been determined. In terms of lift force, the deviation between the two simulations is 6%, while in the drag force the said deviation increases up to 15.5%. Also, the lift and drag coefficient calculated by both simulation results are in good agreement with Airfoil Tools database. [ABSTRACT FROM AUTHOR]

Kolon kanseri tüm kanserler arasında 3. sıklıkta görülen kanser olup; önemli bir morbidite ve mortalite nedenidir. Kolorektal kanserlerde prognozu etkileyen birçok faktör vardır. Son yıllarda tümör yerleşim yerinin de prognoz üzerine etkisini gösteren çalışmalar mevcuttur. Sağ ve sol kolon kanserleri arasında anatomik, embriyolojik, histopatolojik ve genetik açıdan farklılıklar mevcuttur. Evre 4 hastalıkta tümör lokalizasyonu ile prognoz ve tedavi yanıtı arasındaki ilişki daha iyi bilinirken; evre 3 hastalıkta yapılmış yeterince çalışma yoktur. Çalışmamızın amacı; Evre 3 kolon kanser tanılı hastalarda genel sağ kalım ve nüks oranının, tümör lokalizasyonu ile ilişkisini değerlendirmektir.Çalışmaya evre 3 kolorektal kanser tanılı, Akdeniz Üniversitesi Tıp Fakültesinde takip edilen hastalar dahil edildi. 231 hastanın bilgilerine retrospektif olarak hastane veritabanı kullanılarak ulaşıldı. Hastalar tümör lokalizasyonuna göre, literatürdeki çalışmalara benzer olarak sağ ve sol kolon kanseri olarak gruplandırıldı ve verileri analiz edildi.Hastaların 171'inde (%74) sol kolon tümörü; 60'ında (%26) sağ kolon tümörü tespit edildi. Hastaların tümör yerleşim yeri ile nüks oranları arasında anlamlı bir fark saptanmadı (p: 0,82). Sol kolon kanserleri için ortalama GSK 97,5±6,6 (%95 CI, 84,6-110,5) ay, sağ kolon kanserleri için 74,3±5,7 (%95 CI, 63,0-85,5) ay olarak saptandı. Sol kolon kanserlerinde ortalama GSK süresi daha yüksek olmakla birlikte, gruplar arası istatistiksel anlamlı bir fark saptanmadı (p: 0,38). Tutulan metastatik lenf nodu sayısı ile ortalama GSK arasında özellikle sol kolon kanserlerinde anlamlı bir ilişki olduğu gösterildi (p: 0,015).Sonuç olarak; kolon kanserinde tümör lokalizasyonu ile prognoz arasında ilişki olabileceği düşünülmektedir. Bizim çalışmamızda evre 3 hastalıkta tümör lokalizasyonu ile hastalık nüksü ve sağ kalım arasında ilişki net olarak gösterilemedi. Bu konuda ileride yapılacak çalışmaların klinik uygulamada yararlı olabileceği görüşündeyiz.Anahtar Kelimeler: Evre 3 Kolon kanseri, Prognoz, Tümör lokalizasyonu Colon cancer is the third most common cancer among all cancers and it is a major cause of morbidity and mortality. There are many factors that affect prognosis in colorectal cancers. Recent studies showed the effect of tumor location on prognosis. There are differences in anatomic, embryological, histopathological and genetic differences between right and left colon cancers. The relationship between tumor localization in stage 4 disease and prognosis and treatment response is better known; there are not enough studies on stage 3 disease. The purpose of the current study is to evaluate the relationship between overall survival (OS) and recurrence rate with tumor localization in patients with stage 3 colon cancer.Patients diagnosed with stage 3 colorectal cancer and followed up at the Akdeniz University Medical Faculty were included. 231 patients' information was accessed retrospectively using the hospital database. Patients were grouped into right and left colon cancers similar to those in the literature according to tumor localization, and data were analyzed.171 (74%) patients had left colon tumors; whereas right colon tumor was in 60 (26%). There was no significant differences between the tumor location and recurrence rates of the patients (p: 0,82). The mean OS for left colon cancers was 97.5±6.6 (95% CI, 84.6-110.5) months, for right colon cancers it was 74.3±5.7 (95% CI, 63.0-85, 5) months. Although the mean duration of OS was higher in left colon cancers, there was no statistically significant difference between the groups (p: 0,38). A significant correlation was found between the number of metastatic lymph nodes and mean OS, especially in left colon cancers (p: 0.015).As a result; we believe that there may be a relationship between tumor localization and prognosis in colon cancer. In our study, the relationship between tumor localization and survival in stage 3 disease could not be shown clearly. Future work in this regard may be useful in clinical practice.Key Words: Stage 3 colon cancer, Prognosis, Tumor localization 76

Bu tezin temel amacı, İstanbul Üniversitesi Bilgi ve Belge Yönetimi Bölümü örgün öğretim 2. sınıf öğrencilerinin bilgi arama davranışlarını ve bu davranışların Kuhlthau Modeli ile tutarlılık gösterip göstermediğini incelemek olarak belirlenmiştir. Üniversite öğrencilerinin bilgi arama davranışlarını anlamak onların akademik yaşamlarını amaca yönelik geçirmeleri için önemlidir. Burada en büyük sorumluluk öğretim üyeleri ve kütüphanecilere düşmektedir. Öğrencilerin bilgi arama davranışlarını derinlemesine anlayıp onları uygun şekilde yönlendirmek bu iki meslek grubu için de önemlidir. Bu bağlamda üniversite öğrencilerinin bir araştırma ödevi sürecinde yaşadıkları duyguları, karşılaştıkları sorunları, tercih ettikleri bilgi sistemlerini ve diğer bilgi arama davranışlarını bilmek gereklidir. Bilgi arama davranışlarını inceleyen birçok model vardır; Kuhlthau'nun Bilgi Arama Süreci Modeli (BAS) öğrencilerin bilgi arama davranışlarını ve onların bir araştırma ödevi yapma sürecinde yaşadıklarını duygu, düşünce ve eylem yönüyle açıklayan bir modeldir. Kuhlthau' ya göre günümüzde bilgi yetersizliği sorunu yoktur, bu nedenle üzerinde durulması gereken temel konu kullanıcının bilgiye erişim sürecidir. Yukarıda belirtilen amacı gerçekleştirmek üzere, nitel bir araştırma yöntemi olan etnografik yöntem kullanılmış; veriler katılımcı gözlem, görüşme ve anket yoluyla toplanmıştır. Araştırma 2014-2015 öğretim yılı Eylül-Aralık döneminde derslikte, ders dışı üniversite ortamında ve İstanbul Üniversitesi Merkez Kütüphanesi'nde gerçekleştirilmiştir. Elde edilen bulgulara göre öğrencilerin araştırma ödevi yaparken daha çok internet kaynaklarını daha sonra kütüphane kataloğunu kullandıkları, en çok dersin öğretim üyesinden ve arkadaşlarından yardım istedikleri, kütüphane hizmetlerini kullanırken yardıma gereksinim duydukları ve bilgi arama davranışlarının Kuhlthau modeliyle genel olarak uygunluk gösterdiği anlaşılmıştır. Anahtar Sözcükler: Bilgi Davranışı, Bilgi Arama Davranışı, Kuhlthau Modeli, Etnografik Yöntem. The aim of this thesis is to investigate the information seeking behaviors of Istanbul University Information Management Department formal education 2nd degree class students and investigate their information seeking behavior especially emotional situation in the research process according to Kuhlthau Model. Understanding university students' information seeking behaviors is important for spending their academic life according to their aims. Here, the biggest responsibility falls to faculty members and librarians. Understanding of students' information seeking behavior deeply and guiding them appropriately are important for both occupational groups. In this context, it is necessary to know university students' emotions, the problems they encounter and information systems they prefer during a research paper process and know other information seeking behaviors. There are many models to examine information seeking behavior; Kuhlthau's Information Search Process Model (ISP) is a model which explains students' information seeking behaviors and experiences they have while doing a research paper in the aspect of emotion, thought and actions. To Kuhlthau, there is no problem of lack of information today, therefore the basic topic to which we should focus is the user's process of information retrieval. To achieve the objectives stated above, ethnographic method which is a qualitative research method is used; the data is collected via participant observation, interview and questionnaire. The research takes places in the classroom, university after classroom and Istanbul University Central Library between September-December in 2014/2015.According to the data collected, it is understood that while doing research paper students mostly use internet sources, then library catalogue, they want help mostly form faculty member and their friends, they need help while using library services and their information behaviors demonstrate compliance with Kuhlthau Model.Keywords: Information Behavior, Information Seeking Behavior, Kuhlthau Model, Ethnographic Method. 131

ÖZETBu klinik çalışmanın amacı, implant ve diş destekli restorasyonları hemen yüklemenin, implantın primer stabilizasyonuna ve marjinal kemik kaybına etkisinin in vivo olarak değerlendirilmesidir. Bu çalışmaya parsiyel dişsizliğe sahip toplam 26 hasta katıldı. Hastalara 40 adet SLA yüzeyli ITI implant yerleştirildi. Bu implantlar 50 adet doğal dişle bağlanarak hemen yükleme protokolü uygulandı. Çalışmada hemen yüklenen tüm implantlar 1. yılın sonunda osseointegre idi ve implantların 1 yıllık takip sonucundaki başarı oranı %100 olarak bulundu. İmplantların kemik içindeki stabiliteleri başlangıçta, 3. haftada ve 8. haftada rezonans frekansı analizi yöntemi ile ölçüldü. Hemen yüklenen implantların başlangıçtan 3. haftaya kadar ISQ değerlerindeki düşüş ve 3. haftadan 8. haftaya kadar olan artışı istatistiksel olarak anlamlı bulunmuştur (P0.05). Tüm implantların yerleştirilmesi esnasında, daimi protezin yapımını takiben ve 1. yılda periapikal radyografileri alınarak implantların 2. ay ve 1. yılın sonundaki marjinal kemik kayıpları belirlendi. İmplantların marjinal kemik kayıplarının karşılaştırılması istatistiksel olarak tekrarlanabilir varyans analizi yöntemi ile yapıldı. 1. yılın sonunda implantlarda ortalama marjinal kemik kaybı 0.44 ± 0.52 mm bulundu. Diş-implant destekli restorasyonlarda 1 yıllık takip sonunda dişler ve implantlarda ölçülen gingival, kanama ve plak indeks değerlerinde artış görüldü.Anahtar Sözcükler: implant, implant destekli protezler, kemik erimesi, takip çalışması, yaşam ömrü. SUMMARYEvaluation of The Effect Of Immediate Loading with The Tooth And Implant Connected Restorations On Implant Stability And Marginal Bone Loss The object of this study is to evaluate the effect of immediate loading with tooth-implant connected restorations on marginal bone loss and implant stability. 40 SLA ITI implants were connected to 50 teeth and immediately loaded. Stability of the implants was measured using the resonance frequency analysis method at placement, 3rd and 8th weeks. Effect of different jaws, level of primer stability and length of the implants and restorations on the stability of the implants was assessed using the repeated measurement ANOVA method. In order to determine the marginal bone loss around all implants, radiographs were taken at the beginning of implant placement, after 2 months and 1 year. The comparison of marginal bone loss around implants was made using the repeated measurement ANOVA method. At the end of first year, the average marginal bone loss around implants was 0.44 ± 0.52 mm. Success rates were found to be 100 % for implants after 1 year. The decreasing in stability of implants from the beginning to the 3rd week and the increasing in the stability from the 3rd week to the 8th week were found to be statistically significant (p 0.05). At the end of the one year follow-up, sulcus bleeding index, gingival index and plaque index values increased significantly.Keywords: Bone resorption, dental implants, follow-up studies, implant supported dental prosthesis, survival rate

Ilhan Y and Ergun Y
- Abstract
In this editorial, we review the article by Ma and colleagues, published in the World Journal of Gastrointestinal Oncology . Hepatocellular carcinoma (HCC) is a major cause of cancer-related mortality. Although transarterial chemoembolization (TACE) has been used effectively for several years, particularly in patients with intermediate-stage HCC, the quest for the optimal combination therapy to enhance its efficacy and HCC treatment strategies persists. Combining TACE with tyrosine kinase inhibitors (TKIs) like sorafenib or lenvatinib has shown confusing results in improving both progression-free survival and overall survival. Similarly, combining TACE with immune checkpoint inhibitors (ICIs) has demonstrated potential efficacy by reshaping the tumor microenvironment and activating immune responses. Recent studies suggest combining TACE with TKIs and ICIs may offer synergistic effects. Additionally, combining TKIs and ICIs with other local treatments like microwave ablation or hepatic arterial infusion chemotherapy has shown promise in enhancing efficacy. However, more extensive prospective studies are needed to validate these findings. Overall, these combinations represent a promising direction in HCC management, emphasizing the need for further research to optimize treatment outcomes., Competing Interests: Conflict-of-interest statement: The authors declare that there are no potential conflicts of interest with respect to the research, authorship, and publication of the manuscript., (©The Author(s) 2024.

- Abstract
Purpose: The cost-effectiveness of bevacizumab has been the subject of debate, and we aimed to present our own retrospective data on its effect on survival in recurrent epithelial ovarian cancer., Methods: Patients with recurrent ovarian, tubal and primary peritoneal cancer between October 2007 and June 2018 were grouped according to the platinum-free interval. The progression-free and overall survivals of the patients who had received chemotherapy only and chemotherapy with bevacizumab were calculated., Results: Eighty patients had received chemotherapy (CT) only, and 65 had received CT+BV. In platinum-sensitive recurrent epithelial ovarian cancer (PSREOC) patients, the median progression-free survival (PFS) months was 7 months (95% CI; 5.5-8.4) in the group who had received CT only and 13 months (95% CI; 5.8-20.1) in the group who had received CT+BV (p=0.001) and for CT+BV HR (Hazard Ratio):0.39 (95% CI; 0.24-0.64) (p=0.001). The median PFS of platinum-resistant recurrent epithelial ovarian cancer (PRREOC) patients who had received CT only was determined as 2 (95% CI; 1.4-2.5) and as 10 (95% CI; 6.8-13.1) months for patients who had received CT+BV (p=0.001), for patients who had received CT+BV HR: 0.31 (95% CI; 0.17-0.58) (p=0.001). In both PSREOC and PRREOC patients, there was no difference between CT + BV and CT group in terms of overall survival (p=0.978 and p=0.738, respectively)., Conclusion: A significant effect of bevacizumab on the progression-free survival of both platinum-sensitive and platinum resistant recurrent ovarian cancers has been demonstrated; however, this effect failed to impact overall survival. Therefore, it could be recommended to use bevacizumab, considering the cost-effectiveness in undeveloped and developing countries.
