Öğe Türü:Öğe, Evaluating traditional knowledge dissemination in olive cultivation: A delphi method, and fuzzy-AHP approach(Mevlüt Akçura, 2026) Balıkel, Ali ErenTraditional knowledge, methods and practices of olive cultivation are among the intangible cultural heritage elements that are passed down from generation to generation and are an important part of agricultural sustainability. This study develops a scientific evaluation framework to assess the effectiveness of the dissemination of traditional knowledge on olive cultivation. For this purpose, a systematic analysis model was created by combining the Delphi method and the Fuzzy Analytic Hierarchy Process (Fuzzy-AHP). First, the Delphi method was used to collect opinions from academics, representatives of the agricultural sector and people familiar with traditional practices, and the basic evaluation criteria were determined. Then, a comprehensive evaluation model was created by calculating the weights of these criteria with the Fuzzy AHP method. Sub-criteria linked to these indicators were also identified to further elaborate the evaluation process. To test the applicability of the proposed framework, the “Traditional Olive Harvest Festival” program was taken as a case study and analyzed using Delphi and Fuzzy-AHP methods. The results obtained show that the developed evaluation model offers a reliable methodology for the effective dissemination of traditional knowledge on olive cultivation. This study provides strategic directions for the preservation and transfer of traditional knowledge and practices related to olive cultivation to future generations.Öğe Türü:Öğe, Effects of time-restricted eating on circadian cortisol secretion and obesity-related metabolic markers in Cushing’s disease: A pilot study(MDPI, 2026) Soltanova, Lala; İşeri, Ceren; Şahin, Serdar; Kara, Mihriban; Aydın Güçlü, Suzan; Yeşilova, Büşra; Muradov, Ilkin; Kocaman, Banu Betül; Kadıoğlu, PınarPurpose: The aims of this study were to evaluate the feasibility of time-restricted eating (TRE) in patients with Cushing’s disease (CD) and assess its effects on body weight and metabolic parameters. Methods: Twelve CD patients in remission with obesity were enrolled in a TRE program restricting food intake to 10:00–18:00. Anthropometric data, glycemic and lipid profiles, and circadian cortisol secretion were assessed at baseline and post-intervention. Serum cortisol levels were measured at multiple time points to evaluate diurnal patterns. Results: Nine patients completed the study. Over the 12-week period, participants showed a significant reduction in body weight, with median values decreasing from 93.8 kg [83.1–106.5] to 82.6 kg [76.9–100.3] (p = 0.011). Body mass index (BMI) also declined from 37.6 kg/m2 [34.2–39.7] to 34.4 kg/m2 [32.6–38.3] (p = 0.012). No statistically significant changes were observed in fasting glucose, HbA1c, or lipid parameters. Notably, 24 h urinary free cortisol levels significantly decreased (p = 0.01), and serum cortisol showed a downward trend at all measured time points, with the most pronounced reductions during mid-day and evening hours. No clinical or biochemical evidence of CD relapse was observed during the 12-month follow-up. Conclusions: Time-restricted eating is a feasible and well-tolerated dietary approach for patients with CD in remission, promoting weight loss and modest improvements in metabolic markers and cortisol rhythmicity.Öğe Türü:Öğe, Incorporating the psychological perspective into traditional prevention in pediatric dentistry with the PaFein+ Project: trained parents can help(MDPI, 2026) Munteanu, Aneta; Vinereanu, Arina; Sfeatcu, Ruxandra; Tanase, Mihaela; Condurache, Ilie-Andrei; Garret-Bernardin, Annelyse; Putrino, Alessandra; Kuşçu, Özgür Önder; Peker, Sertaç; Kargül, Betül; Galeotti, AngelaBackground: Emotional aspects of early dental experiences have long-lasting effects. This study aimed to assess parents’ childhood dental experiences and their impact on current attitudes toward dental treatment and to evaluate the subjectively perceived usefulness of an educational material focused on psychological management of children’s dental visits. Methods: A cross-sectional descriptive pilot study was conducted using an educational booklet developed and distributed to parents, who read it and completed a short ques tionnaire. Responses received between 27 February–31 March 2025 were analyzed using IBM SPSS Statistics 25. Results: A total of 142 parents (88% mothers) participated. Most participants (83.1%) had a university degree. Negative childhood dental experiences were reported by 44.4% (more frequent among mothers, p < 0.001), and 18.3% had shared these experiences with their children. Emotional discomfort during dental visits was reported by 61.3% of respondents. Dental anxiety was significantly associated with negative childhood experiences (p < 0.001). Parents with higher education were more likely to choose a certified paedodontist for their child than a nearby general dentist (p = 0.002). Most parents (97.9%) found the material provided helpful for managing future dental visits, and 91.6% were willing to share it with others. Conclusions: Childhood dental fear and anxiety may persist into adulthood. Despite the limited generalizability of our results, parents appreciated targeted resources which may support them in promoting positive dental experiences for their children.Öğe Türü:Öğe, Evaluation of tooth discoloration and bleaching response in the presence of clear aligners and attachments(Oxford University Press, 2026) Bilginer, Pervin; Kurnaz, Merve; Başaran, EceObjective To evaluate the influence of clear aligners with and without attachments on tooth discoloration after exposure to common staining beverages, and to assess the bleaching effect of %6 hydrogen peroxide (HP) agent applied through aligners. Methods Forty extracted human premolars were allocated into four groups (n = 10): attachments only, no aligners or attachments, aligners with attachments, and aligners only. Specimens mounted on typodont models and fitted with Invisalign aligners. Typodont models were sequentially immersed in artificial saliva, tea, coffee, and red wine for 6 days each, simulating 6 months of consumption. Aligners were replaced every 12 hours, and staining solutions were renewed daily. Color measurements were recorded at baseline and after each experimental stage using standardized digital photography, and color differences were calculated using the CIEDE2000 (ΔE00) formula. Following the staining protocol, bleaching was performed for 6 days using a 6% HP based gel applied through aligners. Statistical analysis was performed using the Kruskal–Wallis H test (P < .05). Results All groups demonstrated clinically perceptible discoloration after staining. The greatest mean color change was observed in the attachment only group (ΔE00 = 23.30), whereas the lowest discoloration occurred in the aligners only group (ΔE00 = 6.60). Red wine produced the greatest color change among staining agents, while tea and coffee produced comparable staining. Bleaching significantly reduced discoloration in all groups. Conclusion Commonly consumed staining agents produced clinically perceptible tooth discoloration. Composite attachments increased susceptibility to tooth discoloration, whereas aligners showed a protective effect by limiting color change. Bleaching with 6% HP agent applied through aligners significantly reduced discoloration. Dietary habits and the presence of attachments should be considered when managing esthetic concerns during clear aligner therapy (CAT), and bleaching may be recommended without waiting for attachment removal.Öğe Türü:Öğe, A retrospective study of selective dorsal neurectomy for lifelong premature ejaculation: erectile and ejaculatory functions, sensory correlation, and safety evaluation(Wiley, 2025) Başağa, Yaşar; Albayrak, Ahmet Tevfik; Sökmen, Doğukan; Sertkaya, ZülfüIntroduction: Premature ejaculation (PE) is a common male sexual dysfunction and a subset of patients with lifelong PE remainunresponsive to pharmacologic and behavioral therapies. Although selective dorsal neurectomy (SDN) is practiced in certainregions, its safety and efficacy remain underexplored in Western guidelines.Objective: The main aim of this study is to evaluate the clinical outcomes, sensory changes, and safety profile of SDN in patientswith lifelong PE who failed conventional treatments.Methods: In this retrospective cohort study, we reviewed 82 patients with lifelong PE who underwent SDN between January andOctober 2024. Patients were selected based on strict clinical criteria, including failed response to medical therapy and evidence ofpenile hypersensitivity, which was objectively assessed using a biothesiometer. SDN involved preserving at least one dorsal penilenerve <1 mm in each of the three anatomical zones. Pre and postoperative assessments included intravaginal ejaculatory latencytime (IELT), the International Index of Erectile Function-5 (IIEF-5), the PE diagnostic tool (PEDT), and biothesiometry scores.Results: At 6 months postoperatively, mean IELT increased by 241.04 Æ 134.02 s (559.12%, p <0:001), PEDT scores decreased by6.98 Æ 1.66 points (48.07%, p <0:001), and IIEF-5 improved by 1.51 Æ 0.79 points (6.63%, p <0:001). A strong negative correlationwas observed between preoperative sensory thresholds and postoperative improvement in sensory thresholds (Spearman r = −0.83to −0.70, all p <0:001). No major complications, including glans numbness or anorgasmia, were reported.Conclusion: SDN appears to be a safe and effective surgical option for selected patients with lifelong PE who are unresponsive toconservative treatments. The procedure resulted in significant improvements in ejaculatory control with minimal risk whenperformed using a nerve-preserving approach.
