Article Denta-Hybridonet: A Hybrid CNN-Transformer Architecture for Automated Detection of Developmental Dental Anomalies in Pediatric Panoramic Radiographs(Elsevier Sci Ltd, 2026) Eskibaglar, Busra Karaagac; Yavuz, Yelda Polat; Dogan, Gizem Karagoz; Algarni, Ali; Cakmak, Yigitcan; Pacal, IshakAccurate identification of developmental dental anomalies (DDAs) in children is clinically important; however, interpreting panoramic radiographs can still vary across readers because of mixed dentition, anatomical overlap, and variable image quality. This variability may delay recognition and complicate early interventional planning. In this study, we curated a pediatric panoramic dataset of 2,001 radiographs (ages 6-14 years) spanning five categories: Dilaceration, Ectopy, Hypodontia, Taurodontism, and Healthy. All images were independently labeled by three experienced pediatric dentists. To avoid patient-level leakage, the dataset was divided into training, validation, and held-out test sets using a patient-wise split. We propose Denta-HybridoNet, a hybrid convolution-transformer architecture designed to capture both fine-grained tooth morphology and broader, arch-wide contextual patterns. Its InceptionNeXt-gMLP block supports multi-scale local representation learning, which helps the model focus on subtle morphological cues, whereas the Swin-gMLP block provides efficient global context modeling across the dental arch. In addition, a gated multilayer perceptron (gMLP) module refines the feature transformation through context-dependent modulation, strengthening diagnostically relevant signals while reducing the influence of irrelevant variation and radiographic noise. To ensure a fair comparison, we benchmarked Denta-HybridoNet against 22 recent convolutional and transformer-based models under the same training protocol and evaluation conditions. On the held-out test set, the proposed method achieved 91.15% accuracy and 91.20% F1 score, representing the best overall performance among the compared architectures. Ablation studies quantified the contributions of hybrid design and gMLP, and Grad-CAM analyses supported interpretability by highlighting clinically meaningful regions.Article Citation - WoS: 1Citation - Scopus: 1Effects of Nighttime Eating Behavior on Cardiometabolic Health and Sleep: A Crossover Study(Elsevier Sci Ltd, 2025) Kesgin, Yavuz Erkam; Hasbal, Nuri Baris; Copur, Sidar; Incir, Said; Kurtulus, Ozlem; Genc, Candan; Kanbay, MehmetBackground and aims: The impact of night-eating behavior (NEB) on metabolic health remains underexplored, particularly in healthy populations. We have hypothesized that NEB adversely affects metabolic parameters, liver function, and sleep via circadian disruption and neurohormonal alterations. Methods and results: In this single-center crossover study, sixteen healthy adults (aged 18-35 years) with no comorbidities, no medication use, and a body mass index between 18 and 30 kg/m(2) participated in two one-week dietary regimens: regular eating (no food after 7:30 p.m.) and nighttime eating (>= 25 % of daily caloric intake consumed after 9:30 p.m.). Clinical, biochemical, neurohormonal, and respiratory polygraphy data were obtained following each dietary period. The mean age of participants was 27 +/- 4 years. After adjusting for multiple comparisons, nighttime eating behavior (NEB) was associated with significant increases in albuminuria (p = 0.003), serum phosphate (p < 0.001), fasting triglycerides (p = 0.039), and C-reactive protein (CRP; p = 0.01). NEB also elevated serum leptin (p = 0.007), ghrelin (p < 0.001), cortisol (p = 0.041), fibroblast growth factor 21 (FGF-21; p < 0.001), and cytokeratin-18 (p < 0.001), while significantly decreasing melatonin levels (p < 0.001). Sleep study results demonstrated significant increases in the apnea-hypopnea index (AHI; p < 0.001), supine AHI (p < 0.005), oxygen desaturation (7 % +/- 2 % vs. 11 % +/- 3 %; p < 0.001). Conclusion: NEB significantly affects neurohormonal profiles and sleep-related respiratory metrics in healthy individuals, indicating potential adverse effects on cardiometabolic health during short-term evaluation in healthy subjects.Article Citation - WoS: 1Citation - Scopus: 2The Effect of a Video-Based Covid-19 Paediatric Patient Education on State Anxiety in Children With Suspected Covid-19 Admitted To Hospital(Elsevier Sci Ltd, 2023) Sanci, Yagmur; Celik, Serap; Yildiz, SuzanBackground: Anxiety causes the long-term psychological impacts on children during the pandemic.Objective: The aim of this study is to reduce anxiety in paediatric patients and increase their adherence to treatment through a video-based COVID-19 paediatric patient education.Methods: This quasi-experimental study with pretest-posttest single group was carried out in a research hospital's COVID-19 Paediatric Emergency Area in Turkey between May and August 2020. The sample consisted of 128 children aged between 4 and 12 years.Results: In the study, it was found that 50.8% of the children who came to the COVID-19 Paediatric Emergency Area due to suspicion of COVID-19 were boys and their mean age was 8.54 & PLUSMN; 2.62. 21.1% of the children were hospitalised before and 73.4% were afraid of the hospital. State stress scores of the participants before the patient education were higher in those, who didn't attend school between ages of 4-10, than those who went to school. State stress mean scores of the children from all age groups decreased significantly after the education.Conclusions: The video-based paediatric patient education decreases the children's hospital-related anxiety during the pandemic and increased their adherence to treatment.Article Citation - WoS: 4Citation - Scopus: 4The Effect of Formative Assessment on Students' Clinical Knowledge, Skills and Self-Efficacy Levels(Elsevier Sci Ltd, 2024) Kokkiz, Rukiye; Inangil, Demet; Turkoglu, IlaydaAim: This research aims to examine the effect of using formative assessment methods in clinical education on students' knowledge, skills and self-efficacy levels. Background: Formative assessment is used as a method designed to identify areas where students fall short and provide feedback for improvement. Formative assessment and feedback represent fundamental characteristics of quality teaching in higher education and play a decisive role in learning in nursing education. Although educators observe students performing practical tasks during clinical education, evaluation is not made by a structured control list. Therefore, just as nursing students are evaluated with "Skill Checklists" in the OSCE exam, there is a need to evaluate nursing skills during patient care in the clinical field. Design: The study was designed as a pre-test post-test randomized controlled experimental study. Method: Before the research, both groups filled out the self-efficacy form. The experimental group received formative assessment throughout the course. At the end of the semester, all students were given a skills test and asked to fill out the self-efficacy form again. Finally, a knowledge test was administered to the entire class. Results: The average knowledge score of the experimental group is higher than the control group. It was determined that there was a statistical difference of 16.54 points in the average skill scores between the groups. Posttests showed significant differences in skills such as breathing-cough exercise, basic glycemic measurement, subcutaneous injection and blood collection skills. Conclusion: It was determined that the formative assessment method increased nursing students' knowledge, skills and self-efficacy levels regarding basic nursing skills.Article Citation - WoS: 1Citation - Scopus: 1Can Financial Transactions Reveal the Change in Social Fabric Triggered by Urban Regeneration?(Elsevier Sci Ltd, 2024) Seyedkazemi, Seyedpayam; Dass, Zuhal Ozbay; Ozbay, Ayse Elif Ozsoy; Bozkaya, Burcin; Balcisoy, Selim; Daş, Zuhal ÖzbayIn this study, we aimed to investigate the relationship between single-building scaled urban regeneration, driven by the Disaster Risk Transformation Law, and urban segregation in Maltepe district. Following stricter building codes, the district underwent significant demolition and construction between 2014 and 2015. We employ construction data and credit card transaction data to analyze the demographic changes. We find that urban regeneration due to building renewal may have diverse context-dependent effects on the demographic tapestry of communities, their culture and history. While some neighborhoods showed positive response to increased local amenities and resulted in reduced mobility outside their local area, leading to greater income segregation from the rest of the city, others behaved in the opposite direction. Similarly, the transformation process has attracted a more educated and higher-income inflow of residents in some neighborhoods compared to others. Herein, we employ new big data and mobility-driven metrics from computational social science such as diversity, loyalty and assortativity to reveal the link between urban regeneration and segregation. Our findings provide important clues and insights to urban planners for developing urban policies leading to neighborhood designs that are more connected to each other (hence reducing segregation) while still offering modern amenities expected by their residents.Article Citation - WoS: 8Citation - Scopus: 12The Turkish Version of the Patient Safety Competency Self-Evaluation Tool: a Validity and Reliability Study(Elsevier Sci Ltd, 2021) Eskici, Gulcan Taskiran; Kanig, Merve; Ugur, Esra; Seren, Arzu Kader HarmanciAim: To test the validity and reliability of the Patient Safety Competency Self-Evaluation Tool in Turkish, which was developed to evaluate the patient safety competencies of nursing students. Background: In nursing education, it is crucial to provide students with the necessary professional knowledge and skills as well as appropriate attitudes in certain subjects. It is essential to address frequently encountered problems, to train nurses who can be aware of patient safety and improve the quality of nursing education. A valid and reliable measurement tool is needed to evaluate nursing students' current patient safety knowledge, skills and attitudes and review the curriculum and learning objectives in this context. Design: This is a validation study with a cross-sectional design. Methods: The study sample consisted of 417 third and fourth-grade nursing students studying at two universities in Istanbul and volunteered to participate in the research. The study used the Turkish version of the Patient Safety Competency Self-Evaluation Tool was used for data collection. Content validity, construct validity, stability and reliability tests were performed. Data were analyzed using SPSS and AMOS programs. Ethics committee approval and permission from the institutions were obtained. Results: Nursing students' mean age was 21.98 (SD = 1.17). The Scope Validity Index of the scale was calculated as 0.97. As a result of the confirmatory factor analysis performed in the original structure consisting of three dimensions, 12 factors and 41 items, it was found that all items were in the sub-dimensions of the original scale and factor loads were between 0.168 and 0.918. Four models were tested in confirmatory factor analysis and Model 4 had the best-fit indices. They were calculated as: chi(2)/df = 2.38, RMSEA = 0.06 and CFI = 0.91 for Model 4. Cronbach's alpha value of the total scale was 0.941 and ranged between 0.642 and 0.932 in its sub-dimensions. Conclusion: The Turkish version of the Patient Safety Competency Self-Evaluation Tool is valid and reliable to measure nursing students' patient safety competencies.Article Citation - WoS: 8Citation - Scopus: 12The Effect of Aromatherapy and Su Jok Interventions on Post-Cesarean Pain(Elsevier Sci Ltd, 2022) Simsek, Hulya Elmali; Alpar, Sule Ecevit; Ecevi̇t Alpar, Şule; Elmali Şi̇mşek, HülyaObjective: The aim of this study was to determine the effect of aromatherapy and Su Jok interventions as non-pharmacological methods of relieving pain after cesarean section. Materials and methods: This randomized controlled trial was conducted with 120 women who had cesarean delivery in the gynecology and obstetrics department of a training and research hospital between February 9 and October 2, 2019. The participants were allocated to the aromatherapy group, Su Jok group, Su Jok and aromatherapy group, or control group using block randomization based on parity. Su Jok was performed using buckwheat seed; aromatherapy was applied using lavender, eucalyptus, or rose oil. Data were collected using a participant information form and pain was assessed using the Visual Analog Scale. Results: There was no significant difference between the groups in mean pain levels before or after the intervention, although the control group had less initial pain compared to the intervention groups. However, all three intervention groups showed significant decreases in pain levels immediately and 30 min after the intervention compared to pre-intervention levels (p < 0.05). The intervention in all three groups reduced the level of pain. In particular, the pain level of the Su Jok group reached from moderate to mild. There was no significant change in the control group. Conclusions: Aromatherapy and Su Jok interventions performed separately and simultaneously in addition to routine hospital care were more effective in reducing post-cesarean pain than routine care alone.
