    DergiPark: 806159tredBu çalışmanın temel amacı sosyal bilgiler öğretmenlerinin sanal müze kullanım düzeyini ve bu teknik konusunda sahip oldukları tutumları belirlemektir. İlkokul ve Ortaokul öğrencilerinin Sosyal Bilgiler konularını teknolojik imkan ve zaman ölçüsünde daha iyi özümsemeleri için sanal müze uygulamasını kullanmaları gerekmektedir. Bunu için de öncelikle öğretmenlerin rehber olmak ve ardından öğrencileriyle beraber sanal müzeyi kullanabilmesi için bunun farkında olup bu etkinliği özümsemesi gerekmektedir.Sosyal Bilgiler öğretmenlerinin sanal müze kullanımına yönelik tutumlarının belirlendiği bu araştırma karma yöntemle gerçekleştirilmiştir. İstanbul'un farklı ilçelerinden toplam 126 (yüz yirmi altı) öğretmene anket uygulanmıştır. Anket sorularını cevaplayanlar arasında seçilen 13 (on üç) öğretmenle görüşme yapılmıştır. “Sanal Müze Kullanımına Yönelik Tutum Ölçeği” (Peker, 2014) tarafından geliştirilen toplam 21 maddeden oluşan 5'li likert tipi bir ölçek kullanılmıştır.Yapılan araştırmalar sonucunda:Katılımcıların sanal müze kullanımına yönelik toplam puan incelendiğinde madde başı ortalamanın 1,99 olduğu görülmüştür. Bu bağlamda, katılımcıların sanal müze kullanımına yönelik algılarının yüksek olduğu görülmektedir. Cinsiyet değişkeni göz önüne alındığında kadınların ortalamasının, erkeklerin ortalamasından düşük olduğu görülmektedir. Ancak yapılan t-testi sonucunda kadınlar ve erkekler arasından anlamlı bir farkın olmadığı görülmüştür. Ayrıca mesleki kıdem, yaş, eğitim düzeyi değişkenlerinde de anlamlı farkın olmadığı görülmüştür

    Hypoparathyroidism is an orphan disease with ill-defined epidemiology that is subject to geographic variability. We conducted this study to assess the demographics, etiologic distribution, treatment patterns and complication frequency of patients with chronic hypoparathyroidism in Turkey. This is a retrospective, cross-sectional database study, with collaboration of 30 endocrinology centers located in 20 cities across seven geographical regions of Turkey. A total of 830 adults (mean age 49.6 ± 13.5 years; female 81.2%) with hypoparathyroidism (mean duration 9.7 ± 9.0 years) were included in the final analysis. Hypoparathyroidism was predominantly surgery-induced (n = 686, 82.6%). The insulting surgeries was carried out mostly due to benign causes in postsurgical group (SG) (n = 504, 73.5%) while patients in nonsurgical group (NSG) was most frequently classified as idiopathic (n = 103, 71.5%). The treatment was highly dependent on calcium salts (n = 771, 92.9%), calcitriol (n = 786, 94.7%) and to a lower extent cholecalciferol use (n = 635, 76.5%) while the rate of parathyroid hormone (n = 2, 0.2%) use was low. Serum calcium levels were most frequently kept in the normal range (sCa 8.5–10.5 mg/dL, n = 383, 46.1%) which might be higher than desired for this patient group. NSG had a lower mean plasma PTH concentration (6.42 ± 5.53 vs. 9.09 ± 7.08 ng/l, p < 0.0001), higher daily intake of elementary calcium (2038 ± 1214 vs. 1846 ± 1355 mg/day, p = 0.0193) and calcitriol (0.78 ± 0.39 vs. 0.69 ± 0.38 mcg/day, p = 0.0057), a higher rate of chronic renal disease (9.7% vs. 3.6%, p = 0.0017), epilepsy (6.3% vs. 1.6%, p = 0.0009), intracranial calcifications (11.8% vs. 7.3%, p < 0.0001) and cataracts (22.2% vs. 13.7%, p = 0.0096) compared to SG. In conclusion, postsurgical hypoparathyroidism is the dominant etiology of hypoparathyroidism in Turkey while the nonsurgical patients have a higher disease burden with greater need for medications and increased risk of complications than the postsurgical patients

    The purpose of this study is to examine the effects of anthropometry on volleyball serve performance. The researchers recorded serve performances of the volleyball players that participated at the Universities Volleyball League organized by the Turkish University Sports Federation. The Volleyball Serve Scouting Sheet developed by the researchers was used to collect data. The area that the ball was served to, or the type of error (ace, net, out) were recorded on the sheet. Personal information of the athletes who volunteered to participate in the study was collected; height, raised arm height, and body weight were measured. The coefficient of variation and Q-Q plot test were used to test the normal distribution of the data. The significance level was set as p<0.05. Independent samples t-test was used for the statistical analysis. As a result, it was observed that the height and raised arm height of the male volleyball players had an effect on the ability to serve aces (p<0.05).Bu çalışmanın amacı, voleybol oyuncularının antropometrik özelliklerinin servis performanslarına etkisinin incelenmesidir.

    Despite current guidelines, intraperitoneal drain placement after elective colorectal surgery remains widespread. Drains were not associated with earlier detection of intraperitoneal collections, but were associated with prolonged hospital stay and increased risk of surgical-site infections.Background Many surgeons routinely place intraperitoneal drains after elective colorectal surgery. However, enhanced recovery after surgery guidelines recommend against their routine use owing to a lack of clear clinical benefit. This study aimed to describe international variation in intraperitoneal drain placement and the safety of this practice. Methods COMPASS (COMPlicAted intra-abdominal collectionS after colorectal Surgery) was a prospective, international, cohort study which enrolled consecutive adults undergoing elective colorectal surgery (February to March 2020). The primary outcome was the rate of intraperitoneal drain placement. Secondary outcomes included: rate and time to diagnosis of postoperative intraperitoneal collections; rate of surgical site infections (SSIs); time to discharge; and 30-day major postoperative complications (Clavien-Dindo grade at least III). After propensity score matching, multivariable logistic regression and Cox proportional hazards regression were used to estimate the independent association of the secondary outcomes with drain placement. Results Overall, 1805 patients from 22 countries were included (798 women, 44.2 per cent; median age 67.0 years). The drain insertion rate was 51.9 per cent (937 patients). After matching, drains were not associated with reduced rates (odds ratio (OR) 1.33, 95 per cent c.i. 0.79 to 2.23; P = 0.287) or earlier detection (hazard ratio (HR) 0.87, 0.33 to 2.31; P = 0.780) of collections. Although not associated with worse major postoperative complications (OR 1.09, 0.68 to 1.75; P = 0.709), drains were associated with delayed hospital discharge (HR 0.58, 0.52 to 0.66; P &lt; 0.001) and an increased risk of SSIs (OR 2.47, 1.50 to 4.05; P &lt; 0.001). Conclusion Intraperitoneal drain placement after elective colorectal surgery is not associated with earlier detection of postoperative collections, but prolongs hospital stay and increases SSI risk

    No full text
    İstanbul Bilim Üniversitesi, Tıp Fakültesi.Tracheal bronchus is a rarely seen congenital anomaly generally originating from the right lateral wall of the trachea and approximately 2 cm above the carina. It was firstly defined by Sandifort in 1785 and its frequency of incidence in normal population changes between 0.1% and 2%. There are two types called ''Supernumerary'' and ''Displaced''. It is a rarely seen kind of tracheal anomaly although fairly well defined. The cases accompanied by lung cancer are seen more rarely. Nine cases of this association were reported in literature and tracheal bronchus-lung cancer association whose pathological result is undifferentiated large-cell carcinoma has not been stated so far. We present a 75 years old male patient as possibly the first case having tracheal bronchus and large-cell carcinoma association in literature

    The aim of this study was to evaluate the antiapoptotic and proliferative activity of curcumin (Cur) on the ovarian follicles in mice exposed to whole body ionizing radiation (Rd). The mice were exposed to 8.3 gray whole body Rd, and Cur groups were given as a daily dose of 100 mg/kg of Cur for 10 days (10 days before Rd). The ovaries were collected 3 and 12 h after irradiation. To date, no such studies have been performed on antiapoptotic and proliferative activity of Cur on the ovarian follicles in mice exposed to whole body Rd. Analysis of mice ovary after exposure to Rd by terminal-deoxynucleotidyl-transferase-mediated dUTP nick end labeling showed that there were apoptotic cells both in the follicular wall and the antrum, and that the number of follicles showing early atresic features was high 3 h after Rd. On the other hand, analysis of mice ovary 12 h after exposure to Rd showed that the number of follicles containing apoptotic cells with advanced atresic features was significantly higher when compared to the 3-h Rd exposure group. The proliferating cell nuclear antigen-positive granulosa cells were decreased in association with follicular atresia. The groups given treatment were observed to have some benefit from Cur against the damage caused by Rd. The results of this study demonstrate that Cur prevents follicular atresia in Rd-induced apoptosis in ovarian follicles
