Öğe Türü: Yayın , Assessment of Maillard Reaction Products and Oxidative Stress Markers in Commercial Noodle Samples from Türkiye(Elsevier Ltd., 2025) Başdoğan, Hakan; Pehlivanoğlu, Halime; Palabıyık, İbrahim; Güner, Cihat; Öztürk, Nurşah Zeynep; Bostancı, Ferhat; Yaman, Mustafa; Bostancı, Ferhat; Yaman, MustafaThis study systematically investigates for the first time the levels of Maillard reaction products—furosine, malondialdehyde (MDA), glyoxal (GO), and methylglyoxal (MGO)—in commercial noodle samples from Türkiye. A total of 13 noodle samples were analyzed to assess the impact of thermal processing on protein quality degradation and lipid oxidation. The results indicate that furosine levels ranged from 10.83 to 60.28 mg/100 g, with an average of 39.31 mg/100 g, suggesting varying degrees of heat treatment among the samples. MDA levels varied between 33.62 and 198.81 μg/100 g, with an average of 122.46 μg /100 g, indicating lipid oxidation influenced by processing conditions. GO and MGO levels ranged from 110.32 to 196.56 μg/100 g and 9.31–42.06 μg/100 g, respectively, aligning with previously reported levels in heat-processed foods. These findings highlight the need for optimizing processing conditions in noodle production to minimize the formation of undesirable Maillard reaction products and oxidative stress markers. Strategies such as controlled drying temperatures, vacuum drying, and the incorporation of antioxidant-rich ingredients may help reduce the accumulation of these compounds. Future research should explore the long-term dietary exposure to AGEs in noodles and assess their potential health implications.Öğe Türü: Yayın , Adaptation of the Disease-Related Apathy Scale in Adults with Epilepsy into Turkish: A Methodological Study(Wiley, 2025) Bahçecioğlu Turan, Gülcan; Özer, Zülfünaz; Karaman, Seda; Özer, ZülfünazObjective: This study was conducted to culturally adapt the Epilepsy-Related Apathy Scale in Adults with Epilepsy (E- RAS) to Turkish and to assess its psychometric properties in adult epilepsy patients.Methods: A total of 172 epilepsy patients receiving care at the Neurology clinic and outpatient clinic of Fırat University Hospital from February to July 2023 were included in this methodological investigation. The E-RAS was translated into Turkish, and its content and construct validity were thoroughly examined. Construct validity was assessed through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Reliability was evaluated through item analyses, internal consistency analysis, composite reliability coefficient, and mean explained variance analysis.Results: The factor loadings of the scale items ranged from 0.66 to 0.89. The fit index values of the scale were X2 = 467.09, df = 245 (p <0.05), X2/df = 1.9, RMSEA = 0.073, CFI = 0.97, RMR = 0.046, SRMR = 0.057, TLI = 0.97, and AIC = 557.09. The Cronbach's alpha coefficients of the sub-dimensions of the scale ranged from 0.880 to 0.992, and the total Cronbach's alpha coefficient was 0.928. The total McDonald's omega coefficient was 0.916, and the McDonald's omega coefficients of the sub-dimensions ranged from 0.880 to 0.947. The Turkish form of the 24-item and 4-sub- dimensional scale was validated without any changes to the original scale form.Significance: The Turkish adaptation of E-RAS is a valid and reliable instrument for measuring apathy in adult epilepsy patients. Its use in clinical practice is strongly recommended.Plain Language Summary: The E-RAS scale can be used to assess apathy in adults with epilepsy. The was determined that the adapted Turkish form had a similar structure to the original scale. It was determined that the E-RAS scale is valid and reliable in Turkish culture. The fact that the Turkish adaptation of the scale is similar to the original structure and other adapted cultures is a factor that facilitates its use and acceptance in international comparisons. The scale can be used to assess apathy in adults with epilepsy.Öğe Türü: Yayın , The Impact of Peer Victimization and Psychological Symptoms on Quality of Life in Children and Adolescents with FMF(Wiley, 2025) Gülcü, Ayşenur; Kılıçoğlu, Ali Güven; Akıncı, Nurver; Gülcü Üstün, Nur Seda; Kılıçoğlu, Ali GüvenBackground: Familial Mediterranean fever (FMF) is an inherited, chronic,autoinflammatory disease that causes fever, arthritis, and inflammation of serousmembranes. The aim of this study was to investigate the effects of peer bullyingand psychological symptoms on the quality of life of children and adolescents withFMF.Methods: Forty-three children and adolescents aged 8–18 followed up withdiagnoses of FMF and volunteering to take part, and 32 healthy controls wereincluded in this study. Subjects who agreed to participate completed the ChildDepression Inventory (CDI), Screen for Child Anxiety-Related EmotionalDisorders (SCARED), Olweus Bully/Victim Questionnaire (OBQ), and PediatricQuality of Life Questionnaire (PedsQL)- child form. Parents also completed thePediatric Quality of Life Questionnaire (PedsQL)-parent form.Results: Peer bullying victim role, CDI, total SCARED, and SCARED schoolfear scores were significantly higher in the group diagnosed with FMF than in thehealthy controls, while scores for PedsQL completed by children and parents weresignificantly lower. Spearman correlation analysis revealed a significant negativecorrelation between the CDI scores, SCARED scores, and total PedsQL scoresof children with FMF. Quality of life was lower in children and adolescents withFMF exposed to peer bullying in the victim, bully, and bully/victim roles.Conclusions: This study suggests that the presence of peer bullying, depression,and anxiety may have an adverse impact on the quality of life of children andadolescents with FMF.Öğe Türü: Yayın , Adaptation of the Short Version of Santa Clara Strength of Religious Faith Questionnaire in Türkiye(Springer, 2025) Bahçecioğlu Turan, Gülcan; Özer, Zülfünaz; Yavuzer Bayrak, Nisa; Özer, ZülfünazThe present study was conducted to adapt the short version of the Santa Clara Strength of Religious Faith Questionnaire into Turkish and to examine the validity and reliability of the scale. This methodological study was conducted between January and May 2024 with 283 individuals aged 18 and older in Turkey. Data were collected online by using “Personal Information Form” and the “Short Version of the Santa Clara Strength of Religious Faith Questionnaire”. It was found that all participants believed in God. According to the study results, item-based content validity index (I-CVI) was between 0.87 and 1.00, and the scale-based content validity index (S-CVI) was found to be 0.98. Factor loadings of the scale items vary between 0.570 and 0.840. Fit indices of the scale were calculated as follows: X2 = 9.64, df = 4 (p < 0.05), X2/df = 2.41, RMSEA = 0.071, CFI = 0.99, SRMR = 0.021, TLI = 0.98, RMR = 0.012, AIC = 31.64. The overall Cronbach’s alpha value of the scale was 0.860, and the Omega reliability value was 0.866. Short Version of the 5-item Santa Clara Strength of Religious Faith Questionnaire was validated without any changes to the original form. The Turkish version of the Short Version of the Santa Clara Strength of Religious Faith Questionnaire is a valid and reliable instrument for measuring individuals’ strength of religious faith.Öğe Türü: Yayın , Analysis of the Relationship Between Self-Efficacy,Adherence With Diet Therapy and Fluid Control inPatients Receiving Hemodialysis Treatment: A StructuralEquation Analysis(Wiley, 2025) Bahçecioğlu Turan, Gülcan; Karabulut, Ceren; Özer, Zülfünaz; Özer, ZülfünazPurpose: Hemodialysis treatment presents physical, emotional, and social challenges for patients, impacting their overall well-being and daily life. Successful management requires adherence to fluid restrictions, dietary guidelines, and regular medicationintake. This study explored the associations between self-efficacy, dietary adherence, and fluid control in patients undergoinghemodialysis.Methods: This cross-sectional, descriptive study was conducted from 15 April 2024 to 15 June 2024, involving 197 patients re-ceiving hemodialysis at a public hospital and a private dialysis center in Erzurum, eastern Turkey. Data were collected using aPersonal Information Form, the General Self-Efficacy Scale, the Fluid Control in Hemodialysis Patients Scale, and the AttitudeScale for Dietary Therapy of Hemodialysis Patients. Descriptive statistics and structural equation modeling were used for analy-sis. A Bayesian estimator assessed direct and indirect relationships between variables. The model's reliability and validity wereassessed using various statistical tests.Results: Participants had an average age of 53.3 years and an average duration on dialysis of 6.7 years. Of the participants, 91.4%regularly monitored their weight, and 65% regularly monitored edema. The average scores were 28.35 (5.92, SD) on the GeneralSelf-Efficacy Scale, 45.8 (8.12) on the Attitude Scale for Dietary Therapy, and 49.0 (9.05) on the Fluid Control Scale. Self- efficacyhad a significant positive indirect association with fluid control through dietary adherence (β = 0.126, 95% confidence interval[0.008, 0.277]). The total association between self-efficacy and fluid control was also significant (β = 0.624, 95% confidence inter-val [0.483, 0.755]), with dietary adherence partially mediating this relationship. Self-efficacy accounted for 31% of the variance indietary adherence, and the overall model explained 41% of the variance in fluid control.Conclusion: Higher self-efficacy was associated with better dietary adherence and improved fluid control. Dietary adherencepartially mediated the association between self-efficacy and fluid control. Healthcare providers may consider strategies to en-hance self-efficacy in hemodialysis patients to support dietary adherence and fluid control, potentially improving treatmentoutcomes, and quality of life.
