Turkiye’de Enflasyon ve Nispi Fiyat Degiskenligi Iliskisi: VABHO Modelleriyle Uzun Donem Analizi

This study analyzes long-term relation between inflation and relative price variability in Turkey. Vector autoregressive moving average (VARMA) models are used as analyzing methodology. Data base taken into consideration in models are monthly wholesale price index and monthly commodity price indices forming this index between the period 1990:1-2008:12. Findings obtained from VARMA models show that there is a strong positive relationship in the long-term between inflation and relative price variability in Turkey.Inflation, Relative Price Variability, VAR Models, VARMA Models, Iterative Linear Algorithms, OLS.

The Effects of Turkish Central Bank's Interventions Over Currency Rate Volatility

This study aims to identify and analyze the effects of Turkish Central Bank's interventions over currency rate volatility. US Dolar and Euro Returns of Turkish Lira between 04.01.1999 and 24.09.2008 are modelled in the study. Econometric methods used are ARFIMA-GARCH and ARFIMA-FIGARCH models. Findings obtained from model verify the presence of long memory properties, and increasing effects of Central Bank's interventions over currency volatility. According to model's findings, currency shocks have no permanent characteristic and market dynamics will return stability back to markets; therefore, Central Bank should avoid intervening currency markets.Exchange Rate Volatility, Central Bank Interventions, ARFIMA-GARCH and ARFIMA-FIGARCH Models

Ketoprofen gel improves low back pain in addition to IV dexketoprofen: a randomized placebo-controlled trial

Objective Oligoanalgesia is common in emergency departments (EDs), and pain management is of concern for ED physicians. The aim of this study was to reveal the effect of ketoprofen gel in patients presenting with mechanical low back pain to the ED. Method All the study patients received intravenous dexketoprofen additional to study drugs. After dexketoprofen, 2 g of 2.5% ketoprofen gel or placebo was administered to the site with pain and tenderness. Pain relief at 15 and 30 minutes was measured by visual analog scale scores. Rescue drug need and adverse effects were also recorded. Results A total of 140 patients were enrolled into the study. The mean age of the study patients was 35 ± 12, and 56% (n = 79) of them were male. The mean pain reduction at 30 minutes was 52 ± 18 for ketoprofen gel and 37 ± 17 for placebo, and ketoprofen gel was better than placebo at 30 minutes (mean difference, 16 mm; 95% confidence interval, 10-21). Ten patients (14%) in the placebo group and 2 patients (3%) in the ketoprofen gel group needed rescue drug (P = .35). Conclusion Ketoprofen gel improves pain in patients presenting with mechanical low back pain to ED at 30 minutes in addition to intravenous dexketoprofen when compared to placebo. © 2016 Elsevier Inc

An International Comparison on Excessive Credit Expansion, Credit Guarantee Programs and The Risks Arising

Crediting in the banking sector plays an important role in all developed and developing countries. For this reason, it is monitored continuously by public authorities and measures are taken to control credit supply in economic growth periods. On the other hand, in an economic slowdown, when banks are reluctant to increase their credit portfolio, public credit guarantee programs are put into use to increase the credit supply. In this study, a sample covering 26 advanced and emerging economies was analyzed, and the effects of credit gap, credit guarantees and economic growth on credits and arising credit risks were investigated. The findings show that both credits and non-performing loans, an important measure of credit risk, are affected by credit gap, credit guarantees, and economic growth. On the one hand, public credit guarantees positively affect economic growth. On the other hand, though they are widely used for supporting small and medium-sized enterprises, our findings suggest that such expansive credit policies might negatively affect the riskiness of the credit portfolios and soundness of the banking sector

EPIdemiology of Surgery-Associated Acute Kidney Injury (EPIS-AKI) : Study protocol for a multicentre, observational trial

More than 300 million surgical procedures are performed each year. Acute kidney injury (AKI) is a common complication after major surgery and is associated with adverse short-term and long-term outcomes. However, there is a large variation in the incidence of reported AKI rates. The establishment of an accurate epidemiology of surgery-associated AKI is important for healthcare policy, quality initiatives, clinical trials, as well as for improving guidelines. The objective of the Epidemiology of Surgery-associated Acute Kidney Injury (EPIS-AKI) trial is to prospectively evaluate the epidemiology of AKI after major surgery using the latest Kidney Disease: Improving Global Outcomes (KDIGO) consensus definition of AKI. EPIS-AKI is an international prospective, observational, multicentre cohort study including 10 000 patients undergoing major surgery who are subsequently admitted to the ICU or a similar high dependency unit. The primary endpoint is the incidence of AKI within 72 hours after surgery according to the KDIGO criteria. Secondary endpoints include use of renal replacement therapy (RRT), mortality during ICU and hospital stay, length of ICU and hospital stay and major adverse kidney events (combined endpoint consisting of persistent renal dysfunction, RRT and mortality) at day 90. Further, we will evaluate preoperative and intraoperative risk factors affecting the incidence of postoperative AKI. In an add-on analysis, we will assess urinary biomarkers for early detection of AKI. EPIS-AKI has been approved by the leading Ethics Committee of the Medical Council North Rhine-Westphalia, of the Westphalian Wilhelms-University Münster and the corresponding Ethics Committee at each participating site. Results will be disseminated widely and published in peer-reviewed journals, presented at conferences and used to design further AKI-related trials. Trial registration number NCT04165369

Cross-cultural validation of the functional vision questionnaire for children and young people (FVQ_CYP) with visual impairment in the Dutch population: challenges and opportunities

BACKGROUND:To assess cross-cultural validity between Dutch and English versions of the FVQ_CYP, a patient-reported outcome measure developed in the United Kingdom (UK) for children and adolescents with (severe) visual impairment or blindness (VI for brevity) to measure functional vision. METHODS:The 36-item FVQ_CYP was translated and adapted into Dutch using standard guidelines. The questionnaire was administered to Dutch children and adolescents aged 7-17 years (N = 253) with impaired vision (no restrictions regarding acuity). Data were compared to existing UK data of children and adolescents aged 10-15 years (N = 91) with VI (acuity LogMar worse than 0.48). As with the original UK FVQ_CYP validation, a rating scale model (RSM) was applied to the Dutch data. RESULTS:Minor adaptations were needed in translation-rounds. Significant differences in item responses were found between the Dutch and UK data. Item response theory assumptions were met, but fit to the RSM was unsatisfactory. Therefore, psychometric properties of the Dutch FVQ_CYP were analysed irrespective of the original model and criteria used. A graded response model led to the removal of 12 items due to missing data, low information, overlapping content and limited relevance to Dutch children. Fit indices for the remaining 24 items were adequate. CONCLUSIONS:Differences in population characteristics, distribution of responses, non-invariance at the model level and small sample sizes challenged the cross-cultural validation process. However, the Dutch adapted FVQ_CYP showed high measurement precision and broad coverage of items measuring children's functional vision. The underlying reasons for differences between countries in instrument performance are discussed with implications for future studies
