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.
Double product reserve is associated with waist circumference but not body mass index in overweight or obese individuals
(2024) Yiğit, Şafak; Akıncı, B.; Çalıkoğlu, F.; Satman, I.
Background Obesity is an independent risk factor for cardiovascular disease (CVD). Excessive accumulation of adipose tissue in the myocardium leads to structural and functional changes. Body mass index (BMI) is a parameter used to classify overweight and obesity, but it does not distinguish fat-free mass from fat mass and cannot be used to assess body fat distribution. Recent research suggests that abdominal obesity, as measured by waist circumference, is a risk factor for CVD independent of BMI. Purpose In this study, we aimed to investigate the relationship between double product (DP) reserve as a marker of cardiac workload and body composition in overweight and obese individuals. Methods One hundred and forty-one overweight or obese individuals aged 35-65 years (F:105, M:36, mean age=51.48±7.41/years) were included. Body composition (BMI, (mean±SD=35.61±23.31 kg/m2), waist circumference, body fat percentage, waist/hip ratio) was measured. DP was calculated according to the 6-minute walk test (6MWT), which is a submaximal exercise test to estimate myocardial work. It was calculated by multiplying heart rate (HR) by systolic blood pressure (SBP) at rest and after completion of the 6 MWT. DP reserve was calculated as the difference before and after 6MWT. Results DP reserve was not significantly different according to obesity classification (p=0.210, eta-squared=0.032, 95% CI=0.00-0.09) (Table1). DP reserve showed a weakly correlation with waist circumference (r=0.188, p=0.026). No significant relationship was observed between DP reserve and BMI, waist-to-hip ratio and body fat percentage (p>0.05). Conclusion The results of this study showed that cardiac workload estimated with DP reserve was associated with abdominal obesity but not with other body composition parameters. This finding can be interpreted as increased cardiac stress after submaximal exercise in subjects with increased waist circumference regardless of BMI or body fat percentage in overweight or obese subjects.
Digital health readiness in people with cardiometabolic diseases in Turkiye: a prior assessment for the feasibility of technology based cardiac rehabilitation programs
(2025) Ekşi, B. Ülker; Çilbir, Çiğdem Emirza; Yiğit, Şafak; Harputlu, Özge Ertan; Kızılkılıç, Ece; Aslan, Göksen Kuran; Akıncı, Buket
Backround
Digital health readiness refers to the development of health services through digital technologies and the ability to use digital technology to meet health needs and is defined as the main determinant of health. Digital access, usage of digital technology, digital literacy and the development of digital health literacy contribute to the improvement of health processes and are thought to be a useful solution against health problems that may arise in the follow-up of cardiometabolic diseases. Participation in rehabilitation programs is significant in the follow-up of cardiometabolic diseases and digital health literacy plays an important role in self-management of the disease and participation in digital cardiac rehabilitation programs.
Purpose
The aim of our study is to examine the results of the digital usage and skills, which assesses digital health readiness and willingness to learn new digital health tools in individuals with cardiometabolic diseases.
Methods
100participants(mean age=52.28±11.99/years,F:55, M:45) aged 20-80 years and diagnosed with cardiometabolic diseases including hypertension, diabetes mellitus, obesity and cardiac diseases were included in the study. The participants' age ranges were categorized as Group1(20-40 ages between), Group2(41-59 ages between), and Group 3 (60-80 ages between) and educational levels were categorized as high school and below, and university and above. Each participant was presented with 20 statements under the headings of digital usage, digital skills, digital literacy, digital health literacy, and an additional category of digital learnability that Digital Health Readiness Questionnaire and was asked to rate them from 1to5.
Results
There was a significant difference between the age groups in the digital usage category of the participants(F=6.89,p=0.002).The significant difference between group1 and group2 (p=0.034)and between group1 and group3(p=0.001)was in favor of group1.No significant difference was found between age groups in the categories of digital usage, digital technology usage, digital literacy, digital health literacy and digital learnability(p>0.05). In digital usage, internet use had the highest participation rate (4.64±0.91),while activity tracker use was found to be the lowest(2.01±1.67).
Conclusion
This study found that participants aged20–40,especially those with higher education levels, were more likely to use digital devices such as smartphones, laptops, and wearable activity trackers. Younger age and higher education were associated with greater digital usage, learnability, and motivation to develop digital skills. Prior assessment results of this study support that promoting digital health literacy in all age groups can increase the prevention, management and rehabilitation of cardiometabolic diseases by improving healthy lifestyles and control of risk factors.
Exploring conceptual framework of the soundscape of Derinkuyu Underground City
(Acoustical Society of America, 2025) Nas, Sezin; Saher, Konca; Mihci, Gürkan
This research aims to facilitate the experience of the cultural heritage of the ancient Derinkuyu Underground City, one of the largest ancient underground cities in the world, through audio-visual virtual reality (VR) representations of past life in the city; with a focus on defining its acoustics characteristics and soundscape of the past. The objective of this particular study is to define the conceptual framework of the soundscape in the Derinkuyu Underground City based on soundscape standards. The focus is on three spaces: the church used for religious ceremonies; the living area for resting; and the kitchen for food preparation and service. The spatial functions of the church, kitchen, and living spaces were analyzed, sound sources were classified, and the acoustic environment was characterized, considering daily tasks, defining sound sources, establishing reverberation time values by measurements and simulations and describing absorption properties of surfaces. The results showed limitations in describing context due to a lack of literature and historical records. The temporal ambiguity, interconnected spaces, and absence of clear boundaries in Derinkuyu Underground City created a timeless environment where the shared soundscape heightened auditory sensitivity, supporting survival and security needs.
