    Background: To evaluate the incidence, diagnosis and management of GTN among 28 centers in Turkey. Materials and Methods: A retrospective study was designed to include GTN patients attending 28 centers in the 10-year period between January 2003 and May 2013. Demographical characteristics of the patients, histopathological diagnosis, the International Federation of Gynecology and Obstetrics (FIGO) anatomical and prognostic scores, use of single-agent and multi-agent chemotherapy, surgical interventions and prognosis were evaluated. Results: From 2003-2013, there were 1,173,235 deliveries and 456 GTN cases at the 28 centers. The incidence was calculated to be 0.38 per 1,000 deliveries. According to the evaluated data of 364 patients, the median age at diagnosis was 31 years (range, 15-59 years). A histopathological diagnosis was present for 45.1% of the patients, and invasive mole, choriocarcinoma and PSTTs were diagnosed in 22.3% (n=81), 18.1% (n=66) and 4.7% (n=17) of the patients, respectively. Regarding final prognosis, 352 (96.7%) of the patients had remission, and 7 (1.9%) had persistence, whereas the disease was mortal for 5 (1.4%) of the patients. Conclusions: Because of the differences between countries, it is important to provide national registration systems and special clinics for the accurate diagnosis and treatment of GTN.

    Real-life safety and efficacy of vildagliptin as add-on to metformin in patients with type 2 diabetes in Turkey - GALATA study
    (Informa Healthcare, 2015) Ayvaz G.; Keskin L.; Akin T.F.; Dokmetas H.S.; Tasan E.; Ar I.B.; Uren E.; Akber T.; Akdeniz Y.; Bambul N.; Bayraktaroglu T.; Borlu F.; Boz M.; Bozoglu E.; Buyukbese M.A.; Canberk A.; Comlekci A.; Delibasi T.; Demir S.; Eskioglu E.; Guler S.; Gulkan S.; Hekimsoy Z.; Karaca Z.; Keskin M.; Koca N.; Korkmaz H.; Onder E.; Ozisik L.; Peru C.; Sahin M.; Saygili F.; Serin S.; Sezer H.; Sezgin G.; Tasci I.; Tasliyurt T.; Torun A.N.; Tura Bahadir C.; Gursoy Yener G.; Yigit Z.
    Objective: To evaluate tolerability/safety and the efficacy of the combination of vildagliptin plus metformin in a real-life population of patients with type 2 diabetes mellitus (T2DM). Research design and methods: This multicenter, single-arm, 6 month, observational, prospective cohort study was conducted at 39 centers across Turkey. T2DM patients on vildagliptin and metformin for ≤4 weeks were enrolled regardless of their previous antidiabetic therapy. Main outcome measures: Efficacy was evaluated by measuring hemoglobin A1c (HbA1c) levels. Tolerability/safety parameters evaluated included hypoglycemic events, gastrointestinal events, peripheral edema and weight gain. Results: This study enrolled 665 patients with a mean±standard deviation (SD) age of 55.1±10.2 years and female predominance (n=394, 59.2%). Safety was assessed in all enrolled patients. Hypoglycemia was reported in 10 (1.5%) patients (95% confidence interval = 0.8-2.7%). Efficacy was assessed in 289 (43.5%) patients treated for 6±1 months; these patients showed a mean decrease in HbA1c of 0.8% from baseline value of 7.8% (p<0.001). The percentages of patients who achieved HbA1c targets of ≤6.5% and ≤7.0% were significantly increased, from 10.7% to 33.6% and from 22.1% to 52.6%, respectively (p<0.001 each). The decrease in HbA1c was independent of baseline HbA1c (≤8% vs. 8-10% vs. ≥10%), age (≤65 vs. >65 years) and body mass index (<30 vs. ≥30 kg/m2) (p<0.001 each). In total, 136 adverse events (AEs) were observed in 71 (10.7%) patients; 10 (1.5%) patients experienced hypoglycemia and gastrointestinal AEs were most commonly reported (n=29, 4.4%). Conclusions: In a 'real-life' setting, the vildagliptin and metformin combination was associated with significant improvements in reaching target HbA1c levels, even in elderly and obese patients with T2DM. Moreover, vildagliptin and metformin demonstrated a good overall tolerability/safety profile. © 2015 All rights reserved: reproduction in whole or part not permitted.

    University students' perceptions of freedom in leisure
    (Horizon Research Publishing, 2019) Öztürk Ö.T.; Soytürk M.; Serin S.
    The aim of this study was to examine university students’ freedom to engage in leisure activities, and to compare these according to the factors of elective courses taken and course hours, leisure activities frequently participated in, lengths of participation and gender. A total of 410 students, 212 of whom were taking common compulsory courses in their own education programmes, and 198 of whom were taking non-technical elective courses, took part in the study. Quantitative research techniques were used in the study, which was structured on the descriptive model. The Perceived Freedom in Leisure Scale developed by Witt and Ellis (1985) and adapted into Turkish by Yerlisu Lapa and Ağyar (2011), and the Personal Information Form developed by the researchers, were used as data collection tools in the study. The data were evaluated by using the t-test, one-way ANOVA and Mann-Whitney U statistical test methods. According to the research findings, it was determined that students who chose sports courses from among the elective courses and who spent more time participating in their selected courses and in leisure activities had higher perceived freedom in leisure. Whereas no significant difference was observed with regard to the type of leisure activity that the students engaged in, male students’ perceptions of freedom were found to be higher than those of female students. © 2019 by authors, all rights reserved.
