The Effects of Macroeconomic Indicators on Leveraged Forex Volume: Evidence from Turkey

In this study, the effects of macroeconomic indicators on leveraged forex volumes of financial intermediary institutions have been analyzed. The study covers the data for the period 2013Q1-2017Q2 of 16 financial intermediary institutions operating in Turkey. In the study in regards to macroeconomic indicators, BIST 100 Index revenues (BIST), consumer price index (CPI), consumer confidence index (CCI), average rate applied to deposits opened by banks (INT), gold prices (GOLD), money supply (M2), external trade export unit index (EUVI) and unemployment rate (UNEMP) have been used. In the study, the effects of macroeconomic indicators on leveraged forex volume have been examined through panel data analysis. As a result of the panel data analysis, it has been determined that the BIST, M2, EUVI and UNEMP variables have positive significant effects on leveraged forex volume and that the INT variable has negative significant effects on leveraged forex volume. In the study, the effects of CPI, CCI and GOLD variables on leveraged forex volume are statistically insignificant

Preoperative arterial embolization of large liver hemangiomas

PURPOSEWe aimed to investigate the efficacy and safety of preoperative selective intra-arterial embolization (PSIAE) in the surgical treatment of large liver hemangiomas.METHODSData of 22 patients who underwent resection of large liver hemangiomas were retrospectively analyzed. PSIAE was performed in cases having a high risk of severe blood loss during surgery (n=11), while it was not applied in cases with a low risk of blood loss (n=11).RESULTSA total of 19 enucleations and six anatomic resections were performed. Operative time, intraoperative bleeding amount, Pringle period, and blood transfusion were comparable between the two groups (P > 0.05, for all). The perioperative serum aspartate transaminase level was not different between groups (P = 1.000). Perioperative total bilirubin levels were significantly increased in the PSIAE group (P = 0.041). Postoperative hospital stay was longer in the PSIAE group. Surgical complications were comparable between groups (P = 0.476).CONCLUSIONPatients who underwent PSIAE due to a high risk of severe blood loss during resection of large liver hemangiomas had comparable operative success as patients with a low risk of blood loss who were operated without PSIAE. Hence, PSIAE can be used for the control of intraoperative blood loss, especially in surgically difficult cases

Comparison of Diagnostic Performance of PI-RADS V2 and V2.1 and Interobserver Agreement in Both Versions

Objective: To compare the diagnostic performance for the detection of clinically significant prostate cancers and interobserver agreement between PI-RADS v2 and v2.1 Material and Method: The mpMRI images of 258 patients and 394 nodüles included in this retrospective study were obtained on 3T MR and evaluated by two radiologists according to PI-RADS v2 and v2.1. Sensitivity and specificity between v2 and v2.1 compared. Detection rates for clinically significant prostate cancers of upgraded and downgraded lesions in the use of v2.1 from v2 were assessed. Interobserver agreement was assessed using κ statistics. Results: PI-RADS v2.1 and v2 showed higher sensitivity and lower specificity (100%, 52.38%) in peripheral zone and showed higher sensitivity and specificity (92.86%, 98.79%) in transition zone for category ≥4 lesions in the detection of csPCa, not significantly difference was found between the two versions. Interobserver agreement was statistically significant and very weak in the transition zone (κ=0.383, κ=0.279, respectively), very strong in the peripheral zone (κ=0.869) according to both classifications and they were similar. Conclusion: The diagnostic performance of PI-RADS v2 and v2.1 were found similar in detecting clinically significant cancers and all cancers in both zones. The clinically significant cancer detection rate in category 2+1 lesions in the transition zone was higher than in category 2 lesions but it wasn’t statistically significant. Interobserver agreement was low in the transition zone and very strong in the peripheral zone in both versions

The determinants of bank's stock volatility

In this study, it is aimed to determine the factors that affect common stock volatility of banks. In this context, data of companies whose shares are traded in Borsa Istanbul Bank Index (XBANK) are analyzed for the period 2007:06-2018:09 using symmetrical and asymmetrical conditional variance models and panel data analysis. While the dependent variable of the study is common stock volatility, the independent variables are factors of profitability, valuation, financial structure, cost, and size as intrabank elements. As a result of the study, while a statistically significant and positive relationship was determined between common stock volatility and profitability, cost, and valuation rate, a statistically significant and negative relationship was detected between volatility and size. On the other hand, there was no significant relationship between volatility and financial structure. According to the results of the panel data analysis, while one unit increase in profitability, cost, and market value in banks led to an increase of 0.801, 0.085, and 0.025 units in common stock volatility, respectively, one unit increase in size caused a decrease of 0.018 units in stock volatility
