Dyslipidemia is an important risk factor for cardiovascular morbidity and mortality. Although low-density lipoprotein (LDL) is primarily responsible, the importance of triglyceride (TG) and high-density lipoprotein (HDL) has also been recognized. The present study investigated the effect of the atherogenic index of plasma (AIP), in which atherogenic and protective lipoproteins were evaluated together, on the initial flow in patients with ST elevation myocardial infarction. AIP was calculated as log(TG/HDL-cholesterol). Patients included in the study (n = 1535) were divided into Thrombolysis in Myocardial Infarction (TIMI) flow grade 0 and >0. AIP was found to be significantly different between 2 groups (.55 & PLUSMN; .23 vs .67 & PLUSMN; .21; P < .001). AIP was an independent predictor for pre-intervention TIMI flow (Odds Ratio: 2.778). A moderate correlation was found between TIMI frame count measurements, calculated in patients with TIMI 2-3, and AIP (Pearson correlation coefficient: .63, P < .001). In the receiver operating characteristic analysis, AIP showed the highest area under curve (AUC) compared with other lipid parameters for predicting vascular patency. The AUC of AIP was .634, the cut-off value was .59, and the sensitivity and specificity were 67.6% and 68.4%, respectively (P < .001). In conclusion, AIP was found to be an important marker affecting pre-percutaneous coronary intervention TIMI flow.

Background: Glycemic variability (GV) is a prevalent and significant condition observed in critically ill patients. This study aimed to investigate the relationship between early glycemic variability parameters and 28-day mortality in critically ill patients. Methods: A multicenter, prospective, and observational study was performed at five tertiary intensive care units (ICUs) in Turkey. All patients who had more than six blood glucose level (BGL) measures per 24 h were included. The parameters of GV including the SD, MGL, MGD (the difference between the maximal and minimal glucose level), and the CV (the percentage of SD to the MGL) in the first 24 h were recorded. Results: A total of 578 eligible patients were enrolled in the study, of whom 43.6% were women. The mean age of the patients was 68.09 +/- 16.62 years. Overall mortality was 31.5% (n = 182). The glycemic parameters of the CV, SD, and MGD were significantly higher in the non-survivor group than in the survivor group (p = 0.040, 0.006, and 0.002, respectively). The multivariate logistic regression analysis revealed that the CV (OR 1.023; 95% CI 1.004-1.042; p = 0.017) was an independent factor that increased mortality. Spearman's rho correlation analysis revealed a strong (r:0.871) and statistically significant correlation (p < 0.001) between the CV and MGD. Conclusions: The CV calculated within the first 24 h of ICU admission is independently associated with 28-day mortality. The MGD is correlated with the CV and is maybe a practical tool to predict increased risk of mortality at the bedside. However, further studies are needed to establish the independent association of the MGD with mortality.

Zaman, Tolga; Iftikhar, Soofia; Sozen, Caglar; Sharma, Prayas
Earthquake is a fierce and unavoidable natural disaster. The study of aftershocks following an earthquake provides a comprehensive understanding of seismic activity, making it an important area of research. Although it is important to mention that the use of the Poisson distributed population, to estimate the mass mean of rare events such as earthquakes, has been little studied in the literature. In this context, this study proposes a new class of logarithmic type ratio estimators for estimating the mean of a Poisson distributed population in a simple random sampling without replacement. The proposed estimators are obtained using the logarithmic transformation of the ratio estimator, and the expressions for the mean square error (MSE) are also derived to the first order of approximation. The study demonstrates that the proposed logarithmic type estimators are more efficient than the existing estimators, both theoretically and empirically. The Empirical evidence from a real data study conducted using earthquake data from Turkey confirms the superiority of the proposed estimators over the existing estimators. The study provides valuable insights for researchers and practitioners working with Poisson distributed populations and requiring ratio estimators using simple random sampling without replacement.

In this study, lavender essential oil (LEO) was added to ice creams as ingredient at 0, 0.02, 0.05 and 0.1% ratios. Some physicochemical, viscosity, rheological, colorimetric, sensory properties, and pathogen inhibition, including L. monocytogenes ATCC 7644 and S. aureus ATCC 29213, of the ice cream samples with the LEO were investigated. It was determined that the melting rate of the ice creams with the LEO was lower (P<0.05) and the overrun values were higher (P<0.05) than the control sample. The highest L* and a* values were determined in the control samples and the sample with 0.1% LEO, respectively. While C* value of the sample with 0.02% LEO was higher than the other samples (P<0.05), the highest white index (WI) value was determined in the control and the sample with 0.01% LEO. The sample containing 0.01% LEO had the highest viscosity values at 20 and 50 rpm. It was determined that there was no statistically significant difference in the consistency coefficients of the samples (P>0.05) and all samples had pseudolplastic flow. The control sample had the highest sensory score, followed by the sample with 0.02% LEO. It was determined that the LEO addition only had a decreasing effect on the count of S. aureus ATCC 29213.

Eraslan, Selim; Hatipoglu, Ilter Kutlu; Ocak, Fatih; Isik, Fatih; Zeybek, Halil Ibrahim
In this study, the building-ground relationship in the areas affected by the February 6 Kahramanmaras earthquakes was determined, and the risk of building collapse in future earthquakes was analyzed. Remote sensing techniques determined the collapsed building-soil relationship, and the frequency ratio method was applied by utilizing Geographic Information Systems techniques to assess the risk of collapse in earthquakes. According to the research results, 84% of the collapses occurred in flat areas. On the other hand, 49.7% of the collapses occurred in the 0-500 m elevation range. In particular, it was determined that 46% (110.8 km(2)) of the collapsed buildings occurred on alluvial land belonging to the Quaternary period. According to the earthquake frequency analysis of the total 108,812 km(2) area considered in this study, 43.72% of the area is at the Risky level, indicating that a large part of the region is at significant earthquake risk. Moreover, Hatay, Adana, Osmaniye, Sanliurfa, Kahramanmaras, and Malatya are the provinces where the risk of collapse of buildings in an earthquake is high. These results reveal the necessity of analyzing by considering many criteria in determining residential areas in provinces at risk of earthquakes.

Yadav, Subhash Kumar; Arya, Diksha; Koc, Tuba; Zaman, Tolga
The study provides an enhanced estimation of the population mean using known information on an auxiliary variable. An enhanced class of estimators is suggested for the same. The proposed estimator's bias and mean squared error (MSE) are calculated up to the first order of approximation. The optimum values of the characterizing constants are obtained by minimizing the MSE of the proposed estimator. The minimum MSE and the bias values are achieved by optimising the characterizing scalar. The MSE of the proposed estimator has also been compared both conceptually and empirically with the MSEs of competing estimators. Real and simulated data sets are adopted to verify the theoretical prerequisites for the proposed estimator's greater efficiency over competing estimators. The most efficient estimator is recommended for practical utility in different areas of applications and the suggested estimator filfills the requirement.

Setürk, Nazli Keyifli; Bayraktar, Yuksel; Özyilmaz, Ayfer
Corruption affects many economic, political, and social indicators directly and indirectly. One of the economic costs of corruption is a decrease in tax revenues. In societies where corruption is high, administrators taking bribes for excess revenue may reduce tax administration performance. Therefore, corruption and taxes are closely related to each other. This study analyzes the impact of corruption on different tax types in 6 selected transition economies (Estonia, Czech Republic, Hungary, Poland, Latvia and Slovak Republic) in the 1998-2021 and Bootstrap Panel Granger causality method. According to this study, there is unidirectional causality from personal income tax to corruption in Slovakia, from corporate tax and VAT to corruption in Poland, from VAT and SCT to corruption in Hungary, and from VAT to corruption in Latvia. Additionally, there is a bidirectional causal relationship from corruption to personal income tax in Poland and from corruption to corporate tax in the Czech Republic and Hungary, but there is no causal relationship between corruption and VAT and SCT. Personal income and corporate taxes, which require a strong relationship between tax administration and taxpayers, are more affected by corruption than taxes such as VAT and SCT.

Polat, Eray; Arici, Hasan Evrim; Arasli, Huseyin
There has been a growing interest in authentic leadership as a distinctive style of leadership and a dynamic research topic. In this direction, the aim of this study is multifaceted. First, we focus on providing a comprehensive overview of research on authentic leadership (AL), which has attracted substantial research interest in the last few years. Second, we outline the theoretical and nomological network of AL, highlighting antecedents, outcomes, moderators, and mediators. Third, we offer an elaborated future research agenda to enable advances in theory and empirics. We systematically reviewed 182 articles issued in the business management and psychology literature between 2005 and 2021. Interest in AL is growing, and 2020 is the golden year. Developed countries dominate the field. After a rigorous review, we offer a future research agenda with four key themes. The study highlights that AL is critical to the emergence and growth of valuable behaviours, attitudes, and performance at individual, team, and organisational levels. The study provides new research ideas and further conceptualization of AL. We also provide a comprehensive review of why managers should continue to practice AL, where the literature has been, and where it may be headed in the future.

AimsThis study was conducted to determine the correlation between individuals' attitudes toward cancer screenings, cancer information overload, and healthy life awareness.MethodsIn this cross-sectional study, data were collected from 343 people through face-to-face interviews using the socio-demographic characteristics form, attitude scale for cancer screenings, cancer information overload scale, and healthy life awareness scale.ResultsThe mean age of the participants was 47.79 +/- 11.65 and 61.8% of them were women. Older participants had lower positive attitudes toward cancer screenings and healthy life awareness. Higher education level participants displayed more positive attitudes toward cancer screenings. The higher the level of education and income, the higher the cancer information overload. When their cancer information overload increased, their positive attitudes toward cancer screenings and their healthy life awareness, in turn, decreased. As their healthy life awareness increased, they displayed more positive attitudes toward cancer screening, as well. As the participants' awareness in change, socialization, responsibility, and nutrition subscales of healthy life awareness scale increased, they had more positive attitudes toward cancer screenings.ConclusionConsequently, it was determined that the participants had a high level of positive attitudes toward cancer screenings, a moderate level of cancer information overload, and a high level of healthy life awareness.

Tonkaz, Duygu Erkal; Ozpar, Rifat; Tonkaz, Mehmet; Yazici, Zeynep
Background Fat quantification methods in magnetic resonance imaging (MRI) have been studied to differentiate bone marrow pathologies in adult patients; however, scarce literature is available in pediatric patients.Purpose To evaluate the efficacy of the T1 signal intensity value (T1-SIV), out-of-phase/in-phase signal ratio (OP/IP SR), and fat fraction (FF) to differentiate between normal, benign, and malignant pathological processes.Material and Methods A total of 48 pediatric patients with lumbar and pelvic MRI were classified into three groups according to bone marrow pathology (group 1, normal; group 2, benign pathology/reconversion; group 3, malignant). The efficacy of T1-SIV, OP/IP SR, and FF values in differentiating these pathologies was evaluated using Kruskal-Wallis or analysis of variance and followed by Bonferroni or Dunn-Bonferroni tests. Cutoff values for malignant infiltration were defined using ROC analysis.Results Although these values were significantly different in all three groups (P = 0.001-0.008), this difference was not sufficient to discriminate between all groups. Subgroup analyses showed significant differences in T1-SIV between groups 1-3, in OP/IP SR between groups 1-3, 2-3, and 1-2, in FF between groups 1-2 and 1-3 in various regions (P = 0.001-0.049). Cutoff values had a sensitivity and specificity of 90%-100% for OP/IP SR and FF.Conclusion T1-SIV, OP/IP SR, and FF may potentially distinguish normal from pathological bone marrow. OP/IP SR and FF values detected malignant infiltration with high sensitivity and specificity in this study. However, only OP/IP SR may significantly differentiate benign and malignant bone marrow pathologies which needs to be confirmed in the future study with a larger patient population.

To evaluate the predictive value of immature granulocytes in intestinal necrosis in incarcerated hernia. The study included patients who were operated on due to incarcerated hernia. The cases were separated into 2 groups as those with or without bowel resection. Age, gender, hernia type, side, white blood cell count, neutrophil count, neutrophil-lymphocyte ratio, red cell distribution width count, immature granulocyte count, platelet count, and platelet lymphocyte ratio were statistically compared between the groups. There were 27 cases (17.3%) in the group with bowel resection and 127 cases (82.7%) in the group without bowel resection. A statistically significant difference was determined between the groups in respect of the hernia type, white blood cell count, neutrophil count, neutrophil-lymphocyte ratio and immature granulocyte count (p<0.05). The cut-off value of the immature granulocyte count was found to be 0.065, with sensitivity of 63% and specificity of 80%. In multivariate analysis, age over 65 years and immature granulocyte count>0.065 were found to be independent predictors of necrosis development. The immature granulocyte value is a fast, easily accessible and reliable marker that can be used to predict intestinal necrosis in cases of incarcerated hernia.

Küçükosman, Asiye; Uzun, Sumeyye
This study examines the causality relationship between portfolio investments and credit default swaps (CDS) in T & uuml;rkiye. Analysing the dynamics between portfolio investments and CDS premiums, two important variables for financial markets is critical to understanding how risk perception and investment decisions are affected. While portfolio investments are generally considered an indicator of the confidence of foreign investors in the country's economy, CDS premiums are an important risk measure that reflects the country's debt risk and the risk perception of market participants. In this context, examining the relationships between the two variables contributes to the understanding of the effects of investor behavior and risk perception on macroeconomic indicators in financial markets. In the study, the Granger causality test was applied using data from the period 2014Q1-2024Q1. The results obtained show that CDS premiums have a significant and unidirectional causal effect on portfolio investments. Increases in CDS premiums increase investors' risk perception and lead to a decrease in portfolio investments. On the other hand, no causal effect of portfolio investments on CDS premiums was found. These findings emphasize the importance of risk management in terms of portfolio investments in T & uuml;rkiye and reveal that CDS premiums play a role in investor decisions.

LA91 magnesium alloy is a super lightweight magnesium -lithium alloy proposed for next generation materials. In addition to the advantages of these alloys such as low density, high strength-to -weight ratio, specific stiffness and brittleness, these alloys also have disadvantages such as low corrosion resistance and the oxide -carbonate film formed on the surfaces of the alloys cannot provide sufficient corrosion protection even in non-corrosive environments. In this study, micro arc oxidation, one of the coating methods, was applied to LA91 alloy. The surface morphologies of the coatings were characterized and it was aimed to increase the corrosion resistance of LA91 alloy. For this purpose, potentiodynamic polarization tests were carried out in 3.5% NaCl solution at room temperature to draw attention to the protection of the coating. As a result of the tests, it was determined that the oxide coatings raised on the surface
