Öğe Türü:Öğe, The effects of protective sensation on functional capacity, peripheral muscle strength, and balance in patients with type 2 diabetes mellitus(MDPI, 2026) Usul, Melis; Özyılmaz, Semiramis; Tunç, Muhammed; Toluk, ÖzlemBackground: Diabetes-related foot complications are among the most common complica tions in individuals with type 2 diabetes mellitus. The prevention of foot problems that are at risk of developing because of type 2 diabetes mellitus should be addressed within the framework of preventive approaches prior to treatment. The aim of this study was to evaluate protective sensation in people with type 2 diabetes mellitus who have not been diagnosed with early diabetes-related foot complications and to investigate the effects of protective sensation on peripheral muscle strength, balance, and functional capacity. Methods: This study included 42 volunteer patients (56.71 ± 7.59 years) who were followed up with a diagnosis of type 2 diabetes mellitus and met the inclusion criteria. Individuals were evaluated prospectively and via face-to-face interviews. Light-touch, vibration, and discrimination sense was evaluated to determine protective sensation. Peripheral muscle strength (quadriceps femoris, biceps brachii, and hand grip) was measured and a 6 min walking test for functional capacity and balance evaluation were performed. Spearman correlation analysis was conducted using SPSS Statistics 21.0 for data analysis. Results: At least one of the components of protective sensation was moderately correlated with peripheral muscle strength, functional capacity, and balance scores. Reduced protective sensation was also observed in individuals with type 2 diabetes mellitus without neuropa thy. Conclusions: In type 2 diabetes mellitus patients, decreases in light-touch, vibration, and discrimination sense are moderately associated with parameters of peripheral muscle strength, functional capacity, and balance. In patients with type 2 diabetes mellitus, early foot sole sensory examination may prevent the development of neuropathy and support clinicians in early diagnosis.Öğe Türü:Öğe, Using AI large language models to assess dental history in systemic conditions(Springer, 2026) Kandaz, Osman Bilal; Teksöz, Tibet; Avlayıcı, Çağdaş; Sarpkaya, Can; Güven, YeganeIntroduction Technological advancements, particularly in artificial intelligence (AI), are transforming the field of dentistry. AI—including machine learning (ML) and deep learning (DL)—mimics human cognitive processes to enhance diagnostics, treatment planning, and patient care. This study aimed to develop an AI-driven tool for the more effective and efficient evaluation of patients’ dental histories and to compare the time required between AI-assisted and conventional methods. Materials and methods HistorAI analyzes patient anamnesis forms and generates comprehensive reports. A 22-item anamnesis questionnaire, covering both oral and systemic health, guided the structured prompting of AI models (GPT-4 and Gemini). GPT-4 was integrated via an Application Programming Interface (API) to analyze data, provide treatment suggestions, generate prescriptions, and recommend referrals. Evaluation times and outcomes were compared between AI-assisted and conventional methods using descriptive statistics and independent-samples t-tests, with effect sizes calculated using Cohen’s d, and significance set at p<0.01. Results HistorAI successfully evaluated medical and dental histories, identified contraindicated medications and anesthetics, assessed patient complaints, and provided preliminary treatment recommendations. The AI-assisted process significantly reduced the time required to complete dental history assessments compared with conventional methods (p<0.01). A Cohen’s d of 2.599 indicates a substantially higher efficiency for the AI-assisted group. Conclusion The AI-powered tool enhanced efficiency and clinical decision-making in dental practice while maintaining clinician oversight. Further clinical validation and careful consideration of ethical implications are essential to ensure the safe and responsible integration of AI into dental workflows.Öğe Türü:Öğe, Morphometric analysis of hand sesamoid bones using computed tomography and assessment of sex-related differences(Springer, 2026) Çakır, Özgür; Üzel, Murat; Cankorur, Mehmet Akif; Kanık, İdris; Keskin, NecmiPurpose This study aims to conduct a comprehensive morphometric analysis of the sesamoid bones in the hand using com puted tomography (CT) images. Methods This retrospective analysis examined the data of 211 patients who had undergone upper extremity CT imaging, retrieved from the Picture Archiving and Communication System (PACS). Image evaluation was conducted by two inde pendent radiologists using three-dimensional CT reconstructions. The assessment criteria included the presence, number, anatomical location, dimensions (length and width), and volume of the sesamoid bones. For statistical analysis, the Mann Whitney U test was used to examine morphometric differences between sexes, while ANOVA was employed to assess dif ferences among age groups. Results The metacarpophalangeal (MCP) and interphalangeal (IP) joints of the thumb are the most common sites for sesa moid bones. While the prevalence and size of these bones do not show statistically significant differences between genders, their volumes differ in the MCP II and IP I-R joints. The largest sesamoid volume is found in the thumb MCP joint, while the volume generally tends to decrease from the radial side of the hand towards the ulnar side. Conclusion Morphometric analysis of hand sesamoid bones through CT has unveiled notable anatomical variations and gen der-specific differences. These findings are essential for diagnosis and treatment in hand surgery, traumatology, and forensic medicine. For instance, understanding sex-related differences in sesamoid bone sizes can significantly improve identification methods and surgical approaches, ultimately resulting in enhanced patient outcomes.Öğe Türü:Öğe, The effect of taVNS on quality of life in individuals with unilateral upper extremity lymphedema(International Society of Lymphology, 2025) Ökcü, Özge; Saka, Seda; Gümüşsu, KevserOBJECTIVE: Lymphedema is a chronic condition characterized by the accumulation of lymphatic fluid in tissues, which significantly impairs patients' quality of life. This study aimed to evaluate the effects of transcutaneous auricular vagus nerve stimulation (taVNS) on quality of life in individuals with unilateral upper extremity lymphedema. MATERIAL AND METHODS: This study included 27 voluntary participants diagnosed with Stage 2 or 3 unilateral lymphedema and receiving treatment at Gaziosmanpaşa Training and Research Hospital. All participants met the predefined inclusion and exclusion criteria. They were randomly assigned to one of three groups: a group receiving Complex Decongestive Therapy (CDT) alone (n=9), a group receiving CDT combined with transcutaneous auricular vagus nerve stimulation (taVNS) (n=9), and a group receiving CDT combined with sham taVNS (n=9). Assessments were conducted at baseline and after the treatment period. Quality of life and arm-related symptoms were assessed using the Lymphedema Functioning, Disability, and Health Questionnaire (Lymph-ICF), a validated and lymphedema-specific measurement tool. The Lymph-ICF evaluates several domains including physical function, symptom severity, emotional well-being, and social participation. RESULT: The three groups were found to be homogeneous in terms of sociodemographic and clinical characteristics. In within-group analyses, statistically significant improvement was observed only in the CDT group. The mean Lymph-ICF score in this group decreased from 72.64 to 67.67 following treatment (p=0.03), indicating improved functional capacity. Similarly, the group receiving CDT combined with taVNS showed a significant reduction in scores, from 74.13 to 63.46 (p=0.04). Effect size analysis suggested that both CDT and taVNS had a moderate impact on functional capacity. In contrast, the sham taVNS group did not show any significant changes between pre- and post-treatment scores (p=0.83). Between-group comparisons revealed no statistically significant differences in total Lymph-ICF scores either before or after treatment. However, a significant improvement in physical function was found only in the CDT group (p=0.026), and post-treatment comparisons among groups showed a significant difference in this domain (p=0.001). Although some between-group differences were observed in other subdomains, time-related changes generally did not reach statistical significance. CONCLUSION: In conclusion, taVNS demonstrated beneficial effects on specific subdomains of quality of life in individuals with upper extremity lymphedema. Notably, improvements in physical and emotional functioning highlight the potential value of taVNS as a complementary intervention. Further studies are warranted to explore these effects in more detail. The findings suggest that taVNS may serve as an effective adjunct to complex decongestive therapy.Öğe Türü:Öğe, Üniversitedeki akademik ve idari personelin fiziksel aktivite düzeylerinin vücut kompozisyonu ve stres düzeyleri ile ilişkisinin incelenmesi(Iğdır Üniversitesi, 2025) Azboy, Yunus; Büyükturan, Buket; Büyükturan, Öznur; Pehlivanoğlu, Berkay Eren; Ökcü, Özge; Tanşu, Ayşe; Koçer, SunaBu çalışmada, üniversite bünyesinde farklı çalışma alanlarında görev yapan idari ve akademik personelin fiziksel aktivite düzeyleri ile stres seviyeleri ve vücut kompozisyonları arasındaki ilişkinin incelenmesi amaçlanmaktadır. Araştırmanın evrenini, üniversitenin çeşitli birimlerinde görev yapan akademik ve idari personel oluşturmaktadır. Çalışmada örneklem grubu, basit rastgele örnekleme yöntemi kullanılarak belirlenmiş olup, üniversitede çalışan 60 akademisyen ve 39 idari personel olmak üzere toplamda 99 katılımcıdan oluşmaktadır. Katılımcılardan alınan demografik bilgiler, oluşturulan “Demografik Bilgi Formu”na kaydedildi. Katılımcıların fiziksel aktivite düzeyi “Uluslararası Fiziksel Aktivite Anketi”nin kısa formu ile, stres düzeyleri “Algılanan Stres Ölçeği” ile değerlendirildi. Verilerin analizinde IBM SPSS 22 paket programı kullanıldı. Yapılan analizler sonucunda, her iki grupta da genel olarak stres düzeyi ve vücut kompozisyonu arasında anlamlı ilişkiler gözlemlenmiş, ancak çocuk durumu ve fiziksel aktivite düzeyi ile diğer değişkenler arasındaki ilişkiler daha zayıf kalmıştır. Elde edilen bulgular, özellikle stres düzeyinin vücut kompozisyonu üzerinde etkili olduğunu, ancak fiziksel aktivite ve çocuk durumu gibi faktörlerin bu ilişkilerde daha az belirleyici olduğunu göstermektedir.
