    A simple magnetic resonance scoring system for predicting suitability for primary anterior cruciate ligament repair
    (Erzincan Binali Yıldırım Üniversitesi, 2024-08) Kılızay, Yusuf Onur; Erdoğmuş Gülcan, Server; Yılmaz, Hazal Berfin; Yalçın, Gülay; 334080; 392815; 202217; 308202
    Objective: This study developed a simple magnetic resonance imaging (MRI) scoring method to assess the suitability of the anterior cruciate ligament (ACL) remnant for primary repair and aimed to test the success of this scoring method on operative images of patients undergoing early ACL surgery. Methods: The video-recorded operative images of patients who underwent ACL reconstruction and the MRI images of the same patients taken in our hospital were retrieved from the hospital archive. Two surgeons evaluated whether the ACL could be primarily repaired on the video images recorded during the operation. Magnetic resonance primary repairability (MPR) scores and repairability status on video images were compared. Results: The mean age of the patients was 30.4 ± 8.6 years. The evaluation of remnant size on MRI showed moderate agreement between observers (P < .001, Cohen’s kappa = 0.605). The assessment of the repairability score based on MRI and video observation demonstrated substantial agreement between observers (P < .001, Cohen’s kappa = 0.743 and P < .001, Cohen’s kappa = 0.762, respectively). Conclusion: The MR primary repairability score (MPR score) is suitable for use in the decision-making process for the primary repair of the ACL.

    Does Pulmonary Function Testing Affect Autonomic Nervous System Activity?
    (GALENOS PUBL HOUSE, 2026-03) Yalçın, Gülay; Erdoğmuş Gülcan, Server; Kavlak, Erdoğan; 308202; 392815
    Objective: The autonomic nervous system (ANS) regulates vital functions such as heart rate (HR) and respiration. Pulmonary function tests (PFTs), which require forced breathing maneuvers, may influence ANS activity, potentially affecting the accuracy of autonomic measurements. This study aimed to investigate the effects of PFT on ANS activity and to assess the reliability of the test order. Material and methods: Forty-eight healthy university students (32 women, 16 men; mean age 19±0.92 years) participated. ANS activity was assessed by heart rate variability (HRV) analysis using the Elite HRV Corsense device. HRV was recorded at rest in a seated position (first measurement), was repeated after a 5-minute rest (second measurement), and was recorded again following PFT performed with a Medwelt SP10 spirometer (third measurement). Results: Comparison of the first and second measurements showed a statistically significant increase only in the root mean square of successive differences (RMSSD) parameter, with no significant changes in other indices. Comparison of the second and third measurements revealed no significant differences in RMSSD or average HR; however, significant changes were observed in the low-frequency (LF) and high-frequency (HF) components and in the LF/HF ratio. Conclusion: Respiratory maneuvers during PFT may temporarily alter ANS activity, particularly affecting parasympathetic-sympathetic balance. The differences between the first and second measurements emphasize the importance of adequate rest periods before HRV assessment. Measurements taken prior to PFT appear to be more reliable for the accurate evaluation of autonomic function.

    The Effect of Physical Activity and Sleep on Quality of Life and Depression Level in 18- 25 Years Old University Students
    (2025-05) Kavlak, Erdoğan; Erdoğmuş Gülcan, Server; Yalçın, Gülay; 392815; 308202
    Aim: Physical activity,which involves movements exceeding basal energy levels, affects both physical and psychological health.This descriptive study examines the effects of physical activity and sleep on quality of life and depression in university students. Methods: A total of 141 university students aged 18-25 years were included in the study.Sociodemographic data was collected using a form.Physical activity was assessed with the International Physical Activity Questionnaire short form (IPAQ), sleep quality with the Pittsburgh Sleep Quality Index (PSQI), depression levels with the Beck Depression Inventory, and quality of life with the Quality of Life Scale (SF-36). Results: While there was no statistically significant correlation between PSQI,which was used to evaluate sleep duration and quality, and SF-36 sub-parameters Physical Function (r=-0.127;p=0.133) and Physical Role Difficulty (r= - 0.155;p=0.066);There was a weak negative statistically significant relationship between the sub-parameters of Vitality (r=-0.281*;p=0.001),Social Functioning (r=-0.278*;p=0,001),Pain (r=-0.296*;p=0.000), General Health (r=-0.290*;p=0.000). A statistically significant relationship was found between PSQI and Emotional Role Difficulty (r=-0.300*;p=0.000), Mental Health (r=-0.409*;p=0.000) sub-parameters at a moderate negative level. There was also a statistically significant moderate positive correlation between the total scores of PSQI and Beck Depression Inventory (r=0.483*;p=0.000). Conclusions: Adequate sleep and physical activity improve the quality of life and mood in university students,a critical life stage.Therefore, interventions to assess and improve physical activity levels and sleep quality are necessary. In this population, physical activity levels and sleep quality should be questioned and interventions to improve them are needed.
