ABSTRACT

BACKGROUND: Lister’s tubercle (LT) is a palpable bony prominence on the distal radius and is in close proximity to the extensor pollicis longus (EPL) tendon. Despite its clinical relevance, detailed knowledge regarding its morphological variations, anatomical relationships, and developmental aspects remains limited. This study aims to evaluate the morphological variants of LT and its anatomical relationships with EPL using wrist magnetic resonance imaging (MRI), and to propose a novel classification system with potential clinical implications.

MATERIALS AND METHODS: A total of 302 wrist MRI scans (138 males, 164 females; age range 18-44 years) were retrospectively analyzed. Morphometric measurements were recorded, and a five-type classification system with subtypes based on peak prominence and shape was developed. Statistical analyses evaluated morphometric differences by gender, side, and variant type.

RESULTS: Five main LT types were identified: Type 1 (48.34 %) with a dominant radial peak, Type 2 (23.18 %) with a dominant ulnar peak, Type 3 (4.30 %) with only a ulnar peak, Type 4 (20.86 %) with only a radial peak, and Type 5 (3.31 %) with no crest formation. Significant gender-based differences were found in several morphometric parameters, with generally larger measurements in males (p < 0.001). Strong correlations were noted between LT peak heights and EPL positioning, with the groove’s depth and EPL alignment largely determined by the relative height of radial and ulnar peaks.

CONCLUSION: This study highlights previously underappreciated morphological diversity of LT and proposes a clinically relevant classification. These anatomical variations may influence the risk of EPL injury, especially during distal radius fracture management and surgical interventions. Preoperative imaging evaluation of LT type may improve surgical planning and outcomes.

ABSTRACT

PURPOSE: To identify an interchangeable pulmonary regurgitant measure in repaired tetralogy of Fallot by comparing pulmonary regurgitant volume and fraction between serial cardiac computed tomography (CT) and magnetic resonance imaging (MRI).

METHODS: A total of 40 patients (42 paired studies, age at CT examination: 18.6 ± 6.0 years) who underwent cardiac CT and MRI for the cardiac function assessment within 1 year were retrospectively evaluated. The pulmonary regurgitant volume and fraction quantified using CT volumetry were compared and correlated with the values quantified using phase-contrast imaging (reference standard). Furthermore, the degree of agreement between the methods was analyzed using Bland-Altman plot.

RESULTS: No statistically significant difference in the indexed pulmonary regurgitant volume was found between CT volumetry and phase-contrast imaging (p > 0.152). Compared with phase-contrast imaging, CT and MRI volumetry significantly underestimated the pulmonary regurgitant fraction (p = 0.001) and significantly overestimated the right ventricular stroke volume (p < 0.001). These parameters demonstrated high correlations between the two methods (R = 0.632-0.742, p < 0.001). With phase-contrast imaging as reference standard, the bias and 95 % limits of agreement in the indexed pulmonary regurgitant volume and fraction were 2.4 mL/m² and -18.7 to 23.5 mL/m² and -6.3 % and -26.5 to 14.0 %, respectively.

CONCLUSION: The indexed pulmonary regurgitant volume is an interchangeable measure of pulmonary regurgitation on serial cardiac CT and MRI enabling monitoring its severity in repaired tetralogy of Fallot.

ABSTRACT

OBJECTIVES: Background parenchymal enhancement (BPE) and mammographic density (MD) are imaging biomarkers derived from contrast-enhanced mammography (CEM). However, unlike MD, the consistency of BPE across consecutive examinations in pre- and postmenopausal women has remained unexplored.

MATERIALS AND METHODS: A computational search was conducted for all screening CEM exams performed at our facility between December-2012 and January-2024 to identify patients with at least five consecutive negative annual screenings. BPE grades and MD categories were extracted from the official radiology reports, and their variability parameters were statistically compared both between these factors and across age groups.

RESULTS: Forty-five eligible patients at premenopausal age-group were identified (mean age at first scan 38.2 ± 3.4 years, range: 27-42) and a matched postmenopausal age-group was assembled (mean age at first scan 63.7 ± 3.8 years, range: 60-74), resulting in 450 CEMs analyzed. BPE demonstrated greater variability than MD, including fluctuations of at least one category on the scale (71.1-91.1 %), two-category changes (17.8-22.2 %), and transitions between low and high binary categories (17.8-27.7 %) (P < 0.01 for all). Similar rates of two-category BPE transitions (P = 0.65) and shifts between low and high binary categories (P = 0.32) were observed in pre- and postmenopausal women; however, the latter group had a significantly smaller proportion of cases with five consistent grades (P = 0.02).

CONCLUSION: BPE on CEM demonstrates greater longitudinal variability than MD across all age groups and is not more pronounced in premenopausal compared to postmenopausal women. This highlights its dynamic nature and underscores the need for caution when considering BPE in clinical decision-making or as a biomarker, while also suggesting that strict menstrual cycle phase targeting may be less critical.

ABSTRACT

Phytomining is a sustainable mineral extraction method that employs metal-tolerant hyperaccumulator plant species to recover metals from surface soils. Our preliminary study explored the survivability and effectiveness of rare earth element (REE) hyperaccumulators of 45 species when grown in naturally occurring REE-rich soil sourced from Idaho, finding that Idaho native grass Pseudoroegneria spicata is an effective REE hyperaccumulator. This study then evaluated the REE hyperaccumulation ability of P. spicata and Phalaris arundinacea, assessing the performance of seven varieties within each species. Plants were grown in a greenhouse and harvested biomass was ashed or pyrolyzed, acid digested, and characterized by elemental analysis. Results showed that P. spicata and P. arundinacea accumulated an average of 26,044 and 27,761 μg/g total mixed REEs in their shoot tissues, respectively. Species and variety were found to mostly have a significant effect on dry biomass yield while tissue type (root vs. shoot) significantly impacted internal plant REE concentration, with roots accumulating more than shoots. This study concludes that using these hyperaccumulating grass species, especially P. spicata, for Idaho-based phytomining has promise and should be further studied and developed.

ABSTRACT

IntroductionDiscrimination exacerbates disparities among breast cancer survivors (BCS), yet how different reasons for experiencing perceived discrimination (e.g., race, age) influence health remains understudied. We explored the association between self-reported discrimination, psychosocial health, and quality of life (QOL), identified clusters based on reasons for perceived discrimination, and examined differences in QOL and psychosocial outcomes between these clusters.MethodsIn this cross-sectional study, we examined correlations between reasons for perceived discrimination (Everyday Discrimination Scale; EDS), QOL domains (cognitive, physical, social, emotional, and functional QOL measured with FACT-G), social dysfunction (Social Difficulties Inventory), and a psychological distress composite score (included measures of stress [Perceived Stress Scale], anxiety [PROMIS Anxiety], and depression [PROMIS Depression]), among 174 breast cancer survivors (stage 0-IV; ≥21 years). We used k-modes clustering to identify discrimination groups. Differences in demographics, clinical characteristics, and outcomes across clusters were assessed using Chi-square, analysis of variance, covariance, or non-parametric tests, followed by post hoc analyses.ResultsOverall, experiences of discrimination were associated with poorer QOL and psychosocial health (|0.306|<r<|0.452|, P < 0.001). Six distinct clusters emerged based on reasons for perceived discrimination from the EDS. Compared to Cluster 4 (no discrimination), participants in Cluster 1 (discrimination due to gender, age, and physical characteristics) had lower cognitive and physical QOL (4.3 < mean difference [MD]< 5.0, P < 0.001). Participants in Cluster 3 (discrimination due to physical characteristics) had poorer functional QOL, greater social disfunction, and higher psychological distress composite scores (0.3<MD <9.4, P < 0.001) than Cluster 4. Differences between Clusters 2 (discrimination due to gender) and 5 (discrimination due to gender, race/ethnicity) with all other Clusters were not statistically significant (P > 0.05).ConclusionQOL and psychosocial health scores varied between clusters based on reasons for perceived discrimination. Future interventions to improve QOL for breast cancer survivors should consider addressing stigma related to gender, physical appearance, and other forms of discrimination.

ABSTRACT

INTRODUCTION: A recent survey found that 68% of women reported experiencing sexual harassment (SH) during their orthopaedic training. This study aims to (1) characterize Title IX understanding; (2) describe SH occurrences, subtypes, and reporting rates; (3) evaluate the impact of Title IX understanding on SH reporting; and (4) compare these findings by level of training.

METHODS: An anonymous survey was distributed between June 1, 2023, and July 31, 2023, to Ruth Jackson Orthopaedic Society members. Surgeon demographics, SH experiences through the Racialized Sexual Harassment Scale, and Title IX understanding were assessed. Descriptive and comparative statistics analyzed SH occurrences and reporting. Pearson correlation and Fisher exact tests assessed relationships between Title IX knowledge and SH reporting.

RESULTS: Twenty percent (178 of 891) of Ruth Jackson Orthopaedic Society members completed the survey. Fifty-one percent (91/178) of orthopaedic surgeons endorsed experiencing SH during their careers, of whom 35% reported. The most common form of SH was “nonphysical” (34.1%). Formal reporting rates varied by SH type, with “watching” (67.0%) and “fear” (39.0%) being the most reported. The median score on the Title IX survey was 81.8%, with 47% knowing the reporting timeframe and 53% knowing who to report to. No significant associations were found between SH incident reporting rate and Title IX understanding (rho = 0.03, P = 0.9). Attending surgeons had significantly higher Racialized Sexual Harassment Scale scores (25.8 vs. 21.1, P = 0.004) and reported more occurrences (1.1 vs. 0.3, P < 0.001) compared with orthopaedic trainees.

DISCUSSION: Although most orthopaedic surgeons reported experiencing SH and understood Title IX policies, SH reporting rates remained low. Improved understanding of policy is important but may not lead to greater reporting of SH based on this study, suggesting other barriers to reporting.

ABSTRACT

BACKGROUND: Digital tools are increasingly used to support clinical decision-making in dental education. However, the accuracy and efficiency of different support tools, including generative artificial intelligence, in the context of dental trauma management remain underexplored.

OBJECTIVE: This study aimed to evaluate the accuracy of various information sources (chatbot, textbook, mobile app, and no support tool) in conveying clinically relevant educational content related to decision-making in the primary care of traumatically injured teeth. Additionally, the effect of the input strategy on the chatbot’s output response was evaluated.

METHODS: Fifty-nine dental students with limited prior experience in dental trauma were randomly assigned to one of 4 groups: chatbot (based on generative pretrained transformer [GPT]-4o, n=15), digital textbook (n=15), mobile app (AcciDent app 3.5, n=15), and control group (no support tool, n=14). Participants answered 25 dichotomous questions in a digital examination format using the information source allocated to their group. The primary outcome measures were the percentage of correct responses and the time required to complete the examination. Additionally, for the group using ChatGPT-4o, the quality of prompts and the clarity of chatbot responses were independently evaluated by 2 calibrated examiners using a 5-point Likert scale. Statistical analyses included nonparametric analyses using Kruskal-Wallis tests and mixed-effects regression analyses with an α level of .05.

RESULTS: All support tools led to a significantly higher accuracy compared with the control group (P<.05), with mean accuracies of 87.47% (SD 5.63%), 86.40% (SD 5.19%), and 86.40% (SD 6.38%) for the textbook, the AcciDent app, and ChatGPT-4o, respectively. The groups using the chatbot and the mobile app required significantly less time than the textbook group (P<.05). Within the ChatGPT-4o group, higher prompt quality was associated with greater clarity of the chatbot’s responses (odds ratio 1.44, 95% CI 1.13-1.83, P<.05), which in turn increased the likelihood of students selecting the correct answers (odds ratio 1.89, 95% CI 1.26-2.80, P<.05).

CONCLUSIONS: ChatGPT-4o and the AcciDent app can serve dental students as an accurate and time-efficient support tool in dental trauma care. However, the performance of ChatGPT-4o varies with the precision of the input prompt, underscoring the necessity for users to critically evaluate artificial intelligence-generated responses.

ABSTRACT

A recent trial in older adults with anxiety symptoms in primary care found no differences in outcome between an ACT and CBT intervention. The current study aimed to identify moderators and non-specific predictors of treatment response to these two interventions. The sample consisted of 314 older adults who were randomized to either ACT or CBT. Anxiety symptom severity (measured with the GAD-7) was the main outcome variable. Demographics, (psycho)pathology, social support, and psychological processes were examined as predictors. No moderator variables were identified. More severe anxiety and depression symptoms at baseline predicted a worse short- and long-term response to ACT and CBT, while higher levels of mastery predicted a better short-term treatment response in both conditions. When interpreting these results, the lack of sufficient statistical power to detect multiple modest interaction effects should be taken into account. Based on the results of the present study, it is not possible to allocate patients to the intervention that is likely to be most effective for them. The prognostic effects of anxiety and depression symptom severity and mastery may hold implications regarding treatment enhancement strategies in general. The study was registered in the Netherlands Trial Register (NL6131; NTR6270).

ABSTRACT

BACKGROUND: Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most common pediatric liver disease, yet known biological risk factors do not fully explain its development. This study evaluated the association between social determinants of health (SDH)-including income, education, housing, and environmental factors-and MASLD in children with overweight or obesity.

METHODS: This cross-sectional study included children with overweight or obesity evaluated in pediatric gastroenterology clinics, stratified by the presence of MASLD. Participants’ residential census tracts were linked to the California Healthy Places Index (HPI), where higher scores indicate greater socioeconomic advantage. Generalized linear regression models, adjusted for age, sex, race, ethnicity, and body mass index (BMI), assessed associations between SDH and MASLD.

RESULTS: The study included 888 children (mean age: 12.8±2.9 y, mean BMI: 30.6±6.4 kg/m2). Children with MASLD lived in neighborhoods with significantly lower HPI scores than those without MASLD (-0.22 vs. -0.03; 41st vs. 49th percentile, p=0.01). They also resided in areas with significantly lower socioeconomic advantage across multiple HPI subdomains, including housing (-0.16 vs. 0.03; 44th vs. 51st percentile, p<0.001) and economic (-0.38 vs. -0.12; 36th vs. 55th percentile, p<0.001) scores.

CONCLUSIONS: Children with MASLD were more likely to live in neighborhoods with greater socioeconomic and environmental disadvantage than their peers with overweight or obesity but without MASLD. These findings highlight potential SDH targets for public health interventions aimed at reducing MASLD risk in children.

ABSTRACT

This study aims to compare the clinical outcomes of bioresorbable and titanium fixation systems used in anterior maxillary segmental osteotomy (AMSO) procedures, with a focus on skeletal stability, postoperative complications, and hardware-related morbidity. A prospective, randomized clinical trial was conducted on 50 patients undergoing AMSO. Participants were randomly assigned to 2 groups: bioresorbable fixation using poly-L-lactic acid/polyglycolic acid (PLLA/PGA) (n=15) and conventional titanium miniplates (n=35). Standardized panoramic and cephalometric radiographs were taken preoperatively and at 1 and 12 months postoperatively. Primary outcome measures included skeletal stability assessed by horizontal and vertical movement of the anterior maxillary segment. Secondary outcomes included postoperative infection, wound dehiscence, plate palpability, radiographic verification of correct segmental positioning, and the need for hardware removal. At 1 and 12 months, cephalometric radiographs in both groups demonstrated comparable skeletal stability, with no statistically significant differences in relapse rates. The incidence of infection and wound dehiscence was similar across groups. However, the titanium group had a significantly higher rate of hardware removal requests (8.6% vs. 0%, P < 0.05). No major adverse events were reported in either group. Bioresorbable fixation systems provide comparable skeletal stability to titanium plates in AMSO, while eliminating the need for secondary hardware removal. These findings support the selective use of bioresorbable fixation, particularly in patients for whom hardware removal is undesirable.
