ABSTRACT

This study aimed to evaluate the validity and reliability of the Turkish version of the Health Protection Behavior Scale (HPBS). The study was conducted using a two-stage cross-cultural research design in accordance with STROBE guidelines. Data were analyzed using descriptive statistics and exploratory factor analysis (EFA), without performing confirmatory factor analysis (CFA) to avoid the use of the same dataset for model derivation and validation. The overall Cronbach’s alpha for the scale was 0.851, indicating high internal consistency. In terms of construct validity, the Healthy Lifestyle Behaviors Scale II and the WHOQOL-BREF showed strong and moderate positive correlations, respectively (p < 0.05). The psychometric properties of the Turkish version of the HPBS are generally good and acceptable.

ABSTRACT

INTRODUCTION: Diagnosing cemental tears remains challenging, and treatment outcomes can be unpredictable; recommendations for their diagnosis and management are primarily based on case reports and anecdotal experience. Although a classification has been developed for cemental tears, its clinical applicability and importance have yet to be investigated and validated.

AIMS AND OBJECTIVES: This study aims to deepen our understanding of cemental tears through a comprehensive examination of a patient cohort, focusing on: (i) evaluating the cases based on the classification for cemental tears; (ii) assessing clinical presentations, radiographic features, and histopathological characteristics; and (iii) identifying factors that influence diagnosis, treatment approaches, and clinical outcomes.

MATERIALS AND METHODS: This retrospective cohort study evaluated teeth diagnosed with cemental tears at the university’s endodontic clinic from September 2019 to June 2024. The review included case histories, clinical, radiographic and histopathological findings, as well as the treatments performed and their outcomes. Descriptive statistics were used.

RESULTS: Thirty-seven patients with 45 teeth diagnosed with cemental tears were included. Majority of affected teeth (68.9%) had received previous treatment or undergone previously initiated therapy. Among those root treated, most (84.6%) exhibited adequate obturation. Pain, swelling and/or sinus tracts, as well as significant crestal bone loss, were detected in approximately half of the cases. Cone-beam computed tomography (CBCT) scans and direct inspection successfully identified all affected teeth, whereas periapical radiographs (PR) only detected 60.0%. Histopathological analysis revealed cementum in all 37 cases comprising 45 teeth, bone in 11 cases, and cystic lesions in 5 cases. Unfavourable treatment outcomes were observed in 78.9% of teeth classified as Class 4-6. Across all classes, regenerative approaches using enamel matrix derivatives (EMD) achieved favourable outcomes in 44.4% of teeth treated, xenografts in 38.1%, and collagen membranes in 55.6%. Notably, none of the teeth in Classes 4-6 treated with EMD or xenografts demonstrated favourable outcomes.

CONCLUSION: CBCT scans, direct inspection, and histopathological examination demonstrated a higher detection rate compared to PR. Classification is a critical prognostic factor, with Classes 4-6 exhibiting poorer outcomes than others. The impacts of regenerative approaches on periradicular healing appear questionable.

ABSTRACT

AIMS: Malnutrition is common among individuals with intellectual disabilities, and behavioral resistance may limit access to routine oral care. This study examined the association between refusal of oral care and poor nutritional status.

METHODS: In this cross-sectional study, conducted between February and March 2025, we assessed 55 adults with intellectual disabilities living in two designated residential support facilities for persons with disabilities in Fukuoka, Japan. Nutritional status was evaluated using the Mini Nutritional Assessment-Short Form. Oral care refusal was identified from staff records. Functional and body composition data were obtained using the Functional Independence Measure, Barthel Index, and bioelectrical impedance analysis.

RESULTS: The at-risk/malnourished group had significantly lower BMI, fat mass, and functional scores, and a higher rate of oral care refusal (p = 0.007). Logistic regression showed that oral care refusal [OR = 9.23 (95% confidence interval (CI): 1.10-77.33], lower fat mass [OR = 0.78 (0.66-0.92)] were independently associated with poor nutritional status (FIM-Eating [OR = 0.86 (0.53-1.39)], gender [OR = 0.44 (0.08-2.27)], age [OR = 0.96 (0.90-1.02)]). AUC was 0.90 (0.81-0.98).

CONCLUSION: Oral care refusal may indicate increased risk of malnutrition among adults with intellectual disabilities. Larger, longitudinal studies are needed to confirm these findings.

ABSTRACT

BACKGROUND: Progress in mitigating plan degradation due to intrafraction patient motion may involve the identification and management of specific control points that are sensitive to motion. Robust planning in this manner could improve deliverable dosimetry and support advancements toward reducing planning target volume (PTV) margins.

PURPOSE: To improve radiotherapy plan quality robustness in the presence of intrafraction motion by identifying the control-point-specific dosimetric sensitivities. This work explores control-point-specific plan characteristics that impact dosimetry by retrospectively assessing the consequence of simulated patient scenarios for cranial radiotherapy.

METHODS: Single target cranial volumetric modulated arc therapy (VMAT) treatment plans (n = 30) were converted into static field plans and reconstructed by applying 3D control-point-specific motion traces (n = 100) using our in-house MATLAB application. PTV coverage (volume covered by 100% of the prescription isodose, VRx) and the differences in minimum dose delivered to 99% (D_99%) of the gross tumor volume (GTV) were examined across the patient cohort as these are pertinent metrics for each structure. To identify the individual control points where motion led to target coverage loss, three patient plans (5 and 14 were randomly chosen, and 19 with the greatest range in prescription dose coverage) were selected for an area under the curve (AUC) analysis of control point dose volume histograms (DVHs). The mean dose difference in the area under the curve of control point DVHs (mAUC), and the standard deviation of differences (sAUC) were the metrics used in the investigation. Multileaf collimator (MLC) aperture areas were also explored as a function of these metrics.

RESULTS: Under conditions of simulated intrafraction motion, PTV coverage spanned from -2.8% to +0.73% of target volume with 78.6% of the three thousand motion traces resulting in coverage loss. There were no changes in GTV D_99% that exceeded ± 1.5%. For the in-depth control point analysis, MLC aperture areas formed weak to moderately weak correlations with sAUC (r = -0.19, r = -0.42, and r = -0.32, p < 0.01 for patient plans 5, 14, and 19 respectively). In addition, two statistically distinct sub-populations of MLC aperture areas were confirmed by Welch corrected t-tests (p < 0.0001, p = 0.02, p = 0.005 for cases 5, 14 and 19) across a threshold of ± 0.05 mGy in mAUC.

CONCLUSION: This work has demonstrated that the dosimetric impact of intrafractional motion reflects the inherent motion sensitivity of specific control points. Our findings suggest that motion sensitive control points could be selectively targeted for gating to enhance robustness against intrafraction motion and improve dosimetry in support of a PTV margin reduction strategy. Single target cranial plans serve as ideal cases to characterize the consequences of motion at the control point level with the aim of expanding the analysis to other anatomical regions.

ABSTRACT

OBJECTIVE: To evaluate the cost-effectiveness of proficiency-based progression (PBP) training compared to conventional surgical training approaches, and to determine whether PBP training implementation is economically justified when scaled to large numbers of trainees.

METHODS: Economic analysis was performed using data from the prospective, randomised, and blinded Orsi Surgical Skills E-learning Trial (OSSET; ClinicalTrials.gov identifier: NCT04541615) at ORSI Academy (Belgium), where 47 medical trainees without prior robotic surgery experience were randomised into four groups, each with progressively reduced adherence to the PBP methodology. All trainees completed simulation-based training on a validated bladder-urethra anastomosis model, ranging from full PBP training with metric-based assessment and proficiency benchmarks (Group 1) to a traditional apprenticeship model (Group 4). The primary outcome was training cost, evaluated per trainee and based on programme scalability (12-500 trainees), including expenses for accommodation, laboratory time, and metric development. Cost equivalence points and scalability thresholds were identified to compare the financial impact of the four training strategies.

RESULTS: The PBP training was more expensive than conventional methods for small cohorts (e.g. €14 139 vs €7067 per trainee for 12 trainees), but became significantly more cost-effective beyond 25 trainees (equivalence point). At 500 trainees, total PBP training cost was €1.69 million compared to €3.53 million for conventional training, a 110% cost advantage. All differences were statistically significant (P < 0.001).

CONCLUSIONS: We conclude that PBP training is significantly more effective and becomes increasingly cost-efficient as the number of trainees increases. These findings support its integration into high-volume national training programmes, offering a scalable and economically sustainable alternative to apprenticeship-based surgical education.

ABSTRACT

INTRODUCTION: Dietary supplements (DS) are increasingly used in pet care, yet their use in cats remains underexplored, particularly in Southeast Asia. Understanding owner motivations, usage patterns and perceptions is essential for informing veterinary guidance and regulatory policies. This study aims to investigate the prevalence, usage patterns and associated factors of DS use for pet cats among Malaysian cat owners, while comparing perceptions between users and nonusers.

METHODS: A cross-sectional online survey was conducted from March to April 2024 among Malaysian cat owners aged ≥18 years. A structured, content-validated questionnaire assessed sociodemographics, DS usage, perceptions and decision-making. Descriptive statistics, Chi-squared tests and univariate and multivariate logistic regression analyses were used to examine factors associated with DS use.

RESULTS: Among 352 respondents, 58.0% reported administering DS to their cats, with multivitamins (73.0%), omega-3 fatty acids (37.3%), probiotics (26.5%) and fibre supplements (22.1%) being the most common. Key motivations included health maintenance (81.9%) and disease prevention (62.3%). In multivariate logistic regression, DS use was more likely among female owners, those aged 30-39 years, suburban and urban residents, owners of four or more cats and those who had owned cats for more than 5 years. Veterinarians (68.6%) and social media (64.7%) were major information sources. While most users perceived DS as beneficial and accessible, nonusers cited product quality, safety concerns and cost as major barriers.

CONCLUSION: DS use for cats is widespread among Malaysian owners, and selected sociodemographic and ownership characteristics are independently associated with use. Nevertheless, concerns about quality, safety and professional oversight persist. Greater regulatory scrutiny, public education and veterinary-pharmacist collaboration are needed to ensure responsible supplement practices and protect feline health.

ABSTRACT

AIMS: Identify occupational therapy service models in Chilean schools and explore the factors that influence these models, and how they align with inclusive practices.

METHODS: This was a mixed-methods study that included a cross-sectional survey that obtained 241 valid responses from Chilean OTs working in schools, which were analyzed using descriptive statistics. Eighteen of these participants subsequently participated in four online focus groups, discussions that were analyzed using a thematic approach.

RESULTS: Participants provided more frequent direct pull-out services (68.3%) with weekly 45 min sessions, conducted mainly in an OT room or mainstream classroom. Five factors were perceived to influence services: institutional constraints, the educational community’s perspectives on OTs, characteristics of students, a persistent structural demand for a deficit-based approach, and the impact of the COVID-19 pandemic.

CONCLUSIONS: The service model of OTs in Chilean schools was characterized by difficulty aligning with inclusive practices. This reveals a praxis with a markedly medical focus, making it difficult to distinguish it from clinical practice, an essential aspect for the development of OT services in schools.

ABSTRACT

BACKGROUND: Recurrent acute pancreatitis (RAP) or acute-on-chronic flares in chronic pancreatitis (CP) have limited preventive options beyond addressing the underlying aetiology. Statins, due to their anti-inflammatory properties, have been proposed as a potential prophylactic treatment.

OBJECTIVE: We aimed to evaluate whether simvastatin could reduce the recurrence of pancreatitis.

DESIGN: At 23 centres, we conducted a triple-blind, randomised, controlled, superiority trial enrolling patients with at least two episodes of RAP or CP flares in the previous 12 months. Participants were randomly assigned to receive simvastatin or placebo for 1 year. The primary endpoint was the recurrence of pancreatitis. The target sample size was 144 patients; however, an interim analysis was planned in the event of slow recruitment.

RESULTS: A total of 85 patients (42.1% women) were included in the interim analysis. In the intention-to-treat analysis, no significant differences were observed regarding recurrence: 46.2% simvastatin versus 44.4% placebo; OR 1.07, 95% CI 0.43 to 2.66; p=0.88, or time to recurrence. No statistically significant differences were observed in recurrence in per-protocol analysis (35.5% simvastatin vs 41.9% placebo; OR 0.76, 95% CI 0.27 to 2.12; p=0.60). Development of diabetes mellitus was more frequent in the simvastatin group (4 vs 0 patients; OR not calculable, p=0.04).

CONCLUSION: This trial, evaluating simvastatin versus placebo for the prevention of pancreatitis, did not demonstrate a reduction in recurrence rate, although results might be underpowered due to early termination. The relationship between statins in these patients and new-onset diabetes requires further investigation.
