Introduction
We aimed to determine the number of repeated cholesterol (RC) tests and the ratio of unnecessary-repeated cholesterol (URC) tests among patients admitted to Pamukkale University Hospital (Denizli, Turkey) and provide solutions to avoid URC testing.Materials and methods
Total cholesterol (T-cholesterol) tests (N = 86,817) between June 2014 and May 2015 were evaluated. The tests performed more than once per patient were determined as RC test (N = 28,811). RC test with an interval shorter than 4 weeks were determined as URC test (N = 3968) according to the shortest retest interval stated in ACC/AHA blood cholesterol guideline. RC testing included internal medicine, surgery and paediatric outpatients and inpatients. Reference change value (RCV) of total cholesterol was calculated.Results
The 33.1% of the T-cholesterol tests were RC tests (N = 28,811), 13.7% of them were URC tests (N = 3968). Our RCV value was 25%. The percentage change between consecutive tests was less than RCV in 86.1% (N = 3418) of URC tests. URC tests were performed more frequently in patients with desirable total cholesterol value (P < 0.001).Conclusion
There is a significant part of repeated T-cholesterol tests requested in our hospital. URC test requests can be evaluated by laboratories and the obtained data should be shared with clinicians. Laboratories can calculate RCV for the tests they performed and report this value with the test result. To prevent from URC tests, a warning plug-in can be added to hospital information software in accordance with guidelines to prevent from URC test requests.Key words: unnecessary repeated cholesterol test, cholesterol retest interval, reference change value, laboratory costs, preanalytical phase, test requesting 相似文献23.

Chickpea is an important food legume crop of Turkey and is largely grown for human consumption on low moisture or salt-affected soils.The objective of the study was to find the effects of NaCl stress at electrical conductivities of 4.5,8.6,12.7 and 16.3 dS/m and seed sizes (7,8 and 9 mm) on germination and early seedling growth of three popular chickpea cultivars (AKN-97,Gokce and Uzunlu-99).Mean frequency of germination,germination time,germination index,root length,shoot length and seedling fresh weight showed seed size-dependent responses of cultivars to salt stress.In general,small seeds germinated and grew more rapidly compared to medium and large seeds of the same cultivars against all levels of salt stress,with the best results in cultivar Uzunlu-99.No effect of NaCl treatments was observed on frequency of germination; however,a drastic decrease in early seedling growth was recorded at increased NaCl concentrations.Regression analysis results showed a significantly positive rela-tionship (P<0.01) between seed size and mean germination time,whereas a significantly negative relationship was recorded between seed size and germination index,root length,shoot length.Moreover,linear regression values apparently confirmed that increased seed size in each cultivar affected decreased germination index,root and shoot lengths with enhanced mean germination time.Thus,it was concluded that the use of small seeds could considerably reduce the production costs of chickpea in salt-affected soils. 相似文献

Irisin is a myokine that is thought to be secreted in response to exercise that may help to prevent obesity and maintain normal glucose metabolism. In this study we investigated the associations between irisin and glucose homeostasis in middle-aged, overweight and obese men (n?= 144) with impaired glucose regulation, and the impact of exercise training on these relationships. The participants underwent 12 weeks of resistance or aerobic (Nordic walking) exercise training three times per week, 60 minutes per session. Venous blood (n?=?105) and skeletal muscle samples (n?=?45) were obtained at baseline and post-intervention. Compared to controls, Nordic walking, but not resistance training, increased irisin levels in plasma (9.6?±?4.2%, P?=?0.014; 8.7?± 4.9%, P?=?0.087; respectively) compared to controls. When considering all subjects, baseline irisin correlated positively with atherogenic index of plasma (r?=?0.244, P?=?0.013) and 2-hour insulin levels (r?=?0.214, P?=?0.028), and negatively with age (r?=??0.262, P?=?0.007), adiponectin (r?=??0.240, P?=?0.014) and McAuley index (r?=??0.259, P?=?0.008). Training-induced FNDC5 mRNA changes were negatively correlated with HbA1c (r?=??0.527, P?=?0.030) in the resistance training group and with chemerin in the Nordic walking group (r?=??0.615, P?=?0.033). In conclusion, 12-weeks of Nordic walking was more effective than resistance training in elevating plasma irisin, in middle-aged men with impaired glucose tolerance. Thus, the change in irisin in response to exercise training varied by the type of exercise but showed limited association with improvements in glucose homeostasis. 相似文献

This article describes a qualitative study of college mathematics and science faculty (n?=?6) and their engagement in a reform-based program, Japanese lesson study (LS), to change their teaching practices. LS is a process in which a team of four to six teachers jointly design, teach, observe, analyze, and revise a single class lesson. A series of semi-structured, open-ended, interviews was completed with each of the faculty participants. Two sets of assertions were developed from analyses of the data and examples and explanations corroborating each assertion are provided. The results of the study identified issues related to organizational and faculty changes that need to be addressed if faculty responses to pedagogical innovations are to succeed. Implications of the findings for practice and future research are discussed. 相似文献

This sequential explanatory mixed-methods study investigated where predatory/fake journals (PFJs) are founded, which countries’ researchers publish more frequently in PFJs, the identity of the editors of PFJs, why researchers publish in PFJs, and what factors encourage such publications. A survey and semi-structured follow-up interviews were used to collect data. The results indicate that the majority of PFJs are located in developing countries; 119 journals provided incorrect postal addresses; the greatest number of researchers who published in PFJs are from India, Nigeria, and Turkey, suggesting that most of the publications in PFJs are submitted by researchers in developing countries; the interviewed Turkish researchers submitted their articles to PFJs in pursuit of rapid academic promotion; the incentive allowance system encourages researchers to publish in PFJs; and the well-known “publish-or-perish” pressure and unawareness are other potential factors that drive participants to submit their papers to PFJs. 相似文献

This article investigates the major issues and problems of Turkish society that may have an impact on people's daily lives, and the characteristics required of primary school graduates as citizens in response to those issues and problems from the perspectives of parents and educational professionals. Data was collected from 407 parents and 389 professionals using three questionnaires developed by the researchers. Results indicated that priority challenges of primary education were considered to relate to peace, the environment, human rights, democracy, justice and equality. Additionally, primary school graduates were said to require critical thinking, problem solving, language and life skills, as well as open-mindedness, expressiveness, peacefulness, flexibility and sensitivity towards environmental issues. 相似文献

The aim of my study was to explore the nature of changes in pre-service science teachers’ (PSTs’) self-efficacy beliefs toward science teaching through a mixed-methods approach. Thirty-six participants enrolled in a science methods course that included a collaborative peer microteaching (Cope-M). Participants’ science teaching self-efficacy beliefs were measured using paired t-test procedures on Science Teaching Efficacy Beliefs Instrument-B before and after the course. Additionally, structured interviews were conducted with six PSTs. After the Cope-M process, participants continued their education in two subsequent terms, spending time observing professional teaching practices and being involved in science teaching practice in a local middle school. Finally, besides administering the self-efficacy scale again, a questionnaire regarding final perceptions of science teaching and microteaching was administered. Results suggested microteaching sessions provided a supportive and rich environment to develop cognitive, affective, and psychomotor skills in terms of professional teacher behaviors. Moreover, the microteaching sessions provided a supportive medium for enhancing science teaching self-efficacy beliefs. 相似文献
