Social Media Addiction Dimensions, Sleep Disturbances, and Cumulative GPA Among Undergraduate Students: A Cross-sectional Study
(2026) Nas, Sevil; İçöz, Rümeysa Özçalkap
To examine the relationships among social media addiction, sleep quality, and academic performance in university students. This cross-sectional study included 199 university students. Data were collected using a sociodemographic questionnaire, the Social Media Addiction Scale (SMAS), the Pittsburgh Sleep Quality Index (PSQI), and cumulative grade point average (GPA) verified from official academic transcripts. Pearson correlation and multiple linear regression analyses were performed. Most participants (61.8%) used social media for 3–5 hours daily. Total social media addiction was not associated with global sleep quality or cumulative GPA (p >.05). Sleep disturbance was negatively correlated with cumulative GPA (r = −.20, p =.004) and remained independently associated with cumulative GPA in the multivariable analysis (β = −.166, p =.015). Interference with daily life/loss of control was also negatively associated with cumulative GPA (β = −.295, p =.005), whereas deprivation showed a positive adjusted association (β =.247, p =.019). Female students had significantly higher GPAs than male students (p <.001). Sleep disturbance and impaired behavioral control, rather than overall social media addiction, were associated with lower cumulative GPA. © The Author(s), under exclusive licence to Springer Nature Switzerland AG 2026.

(Nature Portfolio, 2026) Dokumacıgil, Gökhan; Dokumacigil, Nur Kodaman; Kargül, Betül
Digital technologies are increasingly integrated into dental practice, yet their adoption may vary according to professional and institutional factors. This cross-sectional study evaluated dentists’ knowledge, attitudes, and practices (KAP) regarding digital dentistry and factors associated with clinical adoption in Turkiye. A total of 225 dentists completed an online questionnaire. Mean knowledge, attitude, and practice scores were 11.2±4.1, 24.4±2.7, and 12.2±5.3, respectively. Public hospital dentists demonstrated lower knowledge and practice scores, while practice scores were also lower among university hospital dentists than among those working in private-sector settings. Knowledge and attitude were positively correlated with practice (ρ=0.311 and ρ=0.250, respectively; both p<0.001). In multivariable analyses, male sex, older age, and private clinic/corporate dental chain employment were independently associated with higher practice scores, whereas public hospital employment was independently associated with lower practice scores. Overall, favourable attitudes towards digital dentistry did not consistently correspond to clinical adoption, indicating differences between attitudes and reported clinical practice. These findings highlight associations between professional and practice-setting characteristics and the clinical use of digital technologies.
KNOWLEDGE, ATTITUDES, AND CLINICAL INTENTIONS OF DENTAL STUDENTS TOWARD BOTULINUM TOXIN USE: A CROSSSECTIONAL STUDY
(2026) Özyetim, Esra Bilgi; Dede, Merve
Background and Aim: Botulinum neurotoxin (BoNT) has gained increasing importance in dental practice for both therapeutic and aesthetic applications. However, its safe and effective use requires adequate knowledge and training. This study aimed to evaluate the knowledge, attitudes, and clinical intentions regarding the use of BoNT among dental students. Materials and Methods: This cross-sectional study was conducted using an online, self-administered questionnaire distributed to dental students at two foundation universities in Turkey. The questionnaire assessed demographic characteristics, knowledge of BoNT (definition, indications, contraindications, and adverse effects), and attitudes toward its clinical use. Data were analyzed using descriptive statistics and Chi-square tests, with statistical significance set at p < 0.05. Results: A total of 506 students participated. Only 34.4% of students correctly identified BoNT as a toxin, and 18.6% correctly identified all clinical indications of BoNT. Knowledge regarding contraindications was particularly limited, with only 2.8% answering correctly. Despite these gaps, 76.7% of students reported willingness to use BoNT in clinical practice, and 77.1% expressed interest in attending training courses. Students who expressed willingness to undergo BoNT injections themselves were significantly more likely to report willingness to administer BoNT clinically (p < 0.05). No consistent increase in knowledge levels was observed across academic years. Conclusion: Dental students demonstrated limited knowledge of BoNT despite a high level of interest in its potential clinical use. These findings provide preliminary information regarding undergraduate dental students’ awareness and perceptions of BoNT
Are sacral stress fractures in young women truly rare? a retrospective MRI analysis of 1970 patients
(BMC, 2026) Bayram, Yusuf; Doğan, Selman; Yalvaç, Bestami; Aksoy, Süleyman Hilmi; Karataş, Muhammed Enes
Background Sacral stress/insufficiency fractures (SSFs) are underrecognized causes of postpartum low-back/pelvic pain and are frequently misattributed to lumbar disc disease. To determine the MRI-based detection rate and clinical/imaging characteristics of SSFs in women aged 18-50 years undergoing lumbosacral MRI, with subgroup analyses for postpartum versus non-postpartum status. Methods Retrospective review of 2400 lumbosacral MRI examinations (January 2020-December 2024) corresponding to 1970 unique women. SSFs were identified by a fellowship-trained musculoskeletal radiologist. Prespecified exclusions (chronic corticosteroid use, major pelvic trauma, incomplete follow-up) yielded the analytic cohort. Group comparisons reported effect sizes (Hedges' g for continuous; risk difference [RD]/odds ratio [OR] for binary) with 95% CIs. Results Crude MRI-based detection rate: 1.52% (30/1,970; 95% CI, 1.07-2.17); analytic MRI-based detection rate: 1.17% (23/1,970; 95% CI, 0.78-1.75). Median age 34 years (range 22-49); 10/23 (43.5%) postpartum. Five cases (21.7%) were initially misdiagnosed. Fractures most often involved the sacral ala (right 12, left 10, bilateral 1). Compared with non-postpartum patients, postpartum patients had lower hemoglobin (**11.5 vs 12.6 g/dL; p = 0.007; Hedges' g = 1.21, 95% CI 0.34-2.09) and hematocrit (**33.9% vs 37.3%; p = 0.007; g = 1.21, 95% CI 0.34-2.09); vitamin D was lower but nonsignificant (**15.4 vs 20.3 ng/mL; p = 0.204; g = 0.53, 95% CI - 0.28-1.34). Overall vitamin D status (n = 21): deficient < 20 ng/mL 11/21 (52.4%), insufficient 8/21 (38.1%), sufficient >= 30 ng/mL 2/21 (9.5%). The reported frequency reflects an MRI-based detection rate within a selected cohort of symptomatic women undergoing lumbosacral MRI and should not be interpreted as the true population prevalence of sacral stress fractures. Conclusion Sacral stress fractures in young women, particularly in the postpartum period, may be underrecognized in symptomatic patients presenting with persistent low-back or pelvic pain. Overlapping symptoms with common musculoskeletal complaints during and after pregnancy often lead to diagnostic delays. MRI remains the gold standard for early detection. Increased clinical vigilance is crucial for prompt diagnosis and effective, non-surgical management.
Nomophobia and its association with musculoskeletal pain and disability in university students: A cross-sectional study
(Churchill Livingstone, 2026) Şahbaz, Tuğba; Şahbaz, Yasemin; Aşık, Hatice Kübra; Uludağ, Murat; Batur, Nergiz
Background Nomophobia, defined as the fear of being without access to a mobile phone, is prevalent among young adults and may have physical and psychological consequences. However, its relationship with musculoskeletal pain and disability remains insufficiently explored. Objective This study aimed to determine the prevalence of nomophobia among university students and investigate its association with musculoskeletal pain and pain-related disability. Methods This cross-sectional study included 714 university students. Nomophobia was assessed using the Nomophobia Questionnaire. Musculoskeletal pain in the neck, upper back, and low back regions was evaluated using the Nordic Musculoskeletal Questionnaire. Disability was assessed using the Neck Disability Index and Oswestry Disability Index. Analyses included group comparisons, correlation analyses, and multivariate logistic regression. Results Nomophobia was highly prevalent, with 58.1% of participants showing moderate and 14.6% severe levels. Neck, upper back, and low back pain were reported by 62.6%, 59.4%, and 53.4% of participants, respectively. Higher nomophobia scores were associated with greater neck and upper back pain intensity and neck- and low back-related disability; however, no significant association was observed with low back pain intensity. After adjustment for sex, BMI, and daily smartphone use, higher nomophobia scores remained associated with higher odds of neck, upper back, and low back pain. Associations were modest. Conclusion Nomophobia was highly prevalent and remained associated with musculoskeletal pain and disability after adjustment, although the associations were modest. These findings highlight the importance of considering behavioral factors in the assessment of musculoskeletal complaints. Longitudinal studies are needed to clarify causal relationships.
