    The Importance of Postural Control in Relation to Technical Abilities in Small-Sided Soccer Games
    (Polish Academy of Science, Committee of Physical Culture, 2016) Edis C.; Vural F.; Vurgun H.
    Making assessments regarding postural control and balance is very important for injury prevention in soccer. However, there has been no study that has associated postural control variables with branch-specific technical properties in a game. The aim of the present study was to determine the relationships between variables designating postural control levels and technical performance variables in different (1:1, 2:2 and 3:3) small-sided games (SSGs). Sixteen trained male amateur soccer players volunteered to take part in the study (age 17.2 ± 1.02 years, body height 176.25 ± 0.07 m, body mass 67.67 ± 13.27 kg). Following familiarization sessions, postural control was evaluated using one-leg and both-leg quiet-stance positions by measuring postural sway with a Tekscan HR Mat™ in anterior-posterior and medial-lateral directions. Later, 1:1, 2:2 and 3:3 SSGs were performed at two-day intervals and the technical variables specified for each game were analyzed. A Spearman's rank-order correlation analysis demonstrated the relationship between postural control and soccer-specific technical variables in 1:1 (r-values ranging from 0.582 to 0.776), 2:2 (rvalues ranging from 0.511 to 0.740) and 3:3 (r-values ranging from 0.502 to 0.834) SSGs. In addition, a Wilcoxon signed rank test revealed differences between SSGs in terms of several variables. The results of the study showed that higher postural control levels are among the important variables that affect success in the performance of technical skills under rival pressure and suddenly changing conditions. Therefore, it is recommended that in addition to its use for injury prevention purposes, balance training should be conducted to improve branch-specific technical skills and to increase the levels of their successful performance in a game. © 2016, Editorial Committee of Journal of Human Kinetics 2016.

    (Elsevier Ltd, 2017) Tekgündüz E.; Demirkan F.; Vural F.; Göker H.; Özdoğu H.; Kiki İ.; Aydoğdu İ.; Kaynar L.; Erkurt M.A.; Çağırgan S.; Beşışık S.; Dağdaş S.; Koca E.; Kadıköylü G.; Gündüz E.; Yılmaz M.; Beköz H.; Ural A.U.; Baştürk A.; Arat M.; Albayrak M.; Öztürk E.; Akyol A.; Bolaman A.Z.; Nevruz O.; Özkan H.A.; Özgür G.; Altuntaş F.
    Autologous hematopoietic cell transplantation (AHCT) is an established treatment option for adult patients presenting with multiple myeloma (MM), Hodgkin lymphoma (HL) and various subtypes of non-Hodgkin lymphoma (NHL) in upfront and/or relapsed/refractory disease settings. Although there are recently published consensus guidelines addressing critical issues regarding autologous hematopoietic progenitor cell mobilization (HPCM), mobilization strategies of transplant centers show high variability in terms of routine practice. In order to understand the current institutional policies regarding HPCM in Turkey and to obtain the required basic data for preparation of a national positional statement on this issue, Turkish Hematology Research and Education Group (ThREG) conducted a web-based HPCM survey. The survey was designed to include multiple-choice questions regarding institutional practice of HPCM in adults presenting MM, HL, and NHL. The representatives of 27 adult HCT centers participated to the study. Here we report the results of this survey shedding light on the real-world experience in Turkey in terms of autologous HPCM mobilization strategies in patients presenting with MM and lymphoma. © 2017 Elsevier Ltd

    The Effect of Cryotherapy on the Prevention of Oral Mucositis and on the Oral pH Value in Multiple Myeloma Patients Undergoing Autologous Stem Cell Transplantation
    (Elsevier Inc., 2021) Baysal E.; Sari D.; Vural F.; Çağırgan S.; Saydam G.; Töbü M.; Şahin F.; Soyer N.; Gediz F.; Acarlar C.; Timur E.; Güngör A.
    Objective: The aim of this study was to evaluate the effectiveness of cryotherapy on the prevention of oral mucositis (OM) and on the oral pH value in patients with multiple myeloma undergoing autologous stem cell transplantation. Data Sources: This nonrandomized controlled clinical trial was carried out in Bone Marrow Transplant Centers of three hospitals with total 32 patients. In addition to standard oral care, a total of 80 minutes of cryotherapy was applied to the experimental group. OM was assessed according to the World Health Organization's Oral Toxicity Scale before chemotherapy and for 21 days after chemotherapy (every day in the first 14 days, then every other day until the 21st day [if not discharged]). Conclusion: According to the findings, cryotherapy did not change the incidence of oral OM, and neither affected the severity of nor decreased the duration of it. Oral pH value was found to be significantly different between the patient groups only before and 1 day after chemotherapy. Implications for Nursing Practice: Cryotherapy is an inexpensive, easy-to-use method with no side effects; it would be beneficial to continue cryotherapy to prevent the development of OM in patients with cancer receiving drugs with a short half-life such as melphalan. It is also recommended to conduct further studies with different chemotherapy drugs with short half-lives to determine its effect on the prevention of OM development. © 2021 Elsevier Inc.

    Efficacy and safety of ruxolitinib in patients with myelofibrosis: A retrospective and multicenter experience in turkey
    (Turkiye Klinikleri, 2021) Soyer N.; Ali R.; Turgut M.; Haznedaroğlu İ.C.; Yilmaz F.; Aydoğdu İ.; Pir A.; Karakuş V.; Özgür G.; Kiş C.; Ceran F.; Ilhan G.; Özkan M.; Aslaner M.; Ince İ.; Yavaşoğlu İ.; Gediz F.; Sönmez M.; Güvenç B.; Özet G.; Kaya E.; Vural F.; Şahin F.; Töbü M.; Durusoy R.; Saydam G.
    Background/aim: The aim of this study is to assess the efficacy and safety of ruxolitinib in patients with myelofibrosis. Materials and methods: From 15 centers, 176 patients (53.4% male, 46.6% female) were retrospectively evaluated. Results: The median age at ruxolitinib initiation was 62 (28–87) and 100 (56.8%) of all were diagnosed as PMF. Constitutional symptoms were observed in 84.7%. The median initiation dose of ruxolitinib was 30 mg (10–40). Dose change was made in 69 (39.2%) patients. Forty seven (35.6%) and 20 (15.2%) of 132 patients had hematological and nonhematological adverse events, respectively. The mean spleen sizes before and after ruxolitinib treatment were 219.67 ± 46.79 mm versus 199.49 ± 40.95 mm, respectively (p < 0.001). There was no correlation between baseline features and subsequent spleen response. Overall survival at 1-year was 89.5% and the median follow up was 10 (1–55) months. We could not show any relationship between survival and reduction in spleen size (p = 0.73). Conclusion: We found ruxolitinib to be safe, well tolerated, and effective in real-life clinical practice in Turkey. Ruxolitinib dose titration can provide better responses in terms of not only clinical benefit but also for long term of ruxolitinib treatment. © TÜBİTAK.

    Prospective registry of adult patients receiving therapeutic plasma exchange with a presumptive diagnosis of thrombotic microangiopathy (TMA): The Turkish hematology research and education group (ThREG)-TMA02 study
    (Elsevier Ltd, 2021) Akpınar S.; Tekgunduz E.; Erkurt M.A.; Esen R.; Yılmaz M.; Karakus V.; Vural F.; Gediz F.; Aydogdu I.; Kaynar L.; Korkmaz S.; Goker H.; Kelkitli E.; Ayyıldız O.; Demirkan F.
    Thrombotic microangiopathy(TMA) is a pathological diagnosis characterized by abnormalities of small vessels leading to microvascular thrombosis of arterioles and capillaries. The current prospective, non-interventional, multicenter (n:18) study aimed to define distribution of different TMA forms in adult Turkish patients who were referred for therapeutic plasma exchange (TPE) for a presumptive diagnosis of TMA. Patients with serum ADAMTS13 activity <5% were diagnosed as acquired thrombotic thrombocytopenic purpura (aTTP). Patients presenting with ADAMTS13 activity 6–10 % / normal renal function and patients with ADAMTS13 activity >10 %, normal renal function and no secondary TMA were treated as unclassified TMA. The study included a total of 97 patients (female: 60; male: 30) with a median age of 48 (18−74). Detailed evaluation at 1 month after hospital admission revealed aTTP, secondary TMA, infection/complement-associated hemolytic uremic syndrome and unclassified TMA in 32 (33 %), 33 (34 %), 26 (27 %) and 6 (6%) patients respectively. As subclassification of various TMAs will dictate specific therapy, proper diagnosis in a timely manner is of utmost clinical significance. © 2021 Elsevier Ltd
