Objective: To compare the psychometric properties of scales top measure activities of daily living, constructed with different scaling methods, and to check whether the most complex scales have higher discriminatory capacity.
Method: Sample of elderly people from the Spanish Survey on Disability, Personal Autonomy and Dependency We used 14 items that measured activities of daily living. Five scaling methods were applied: Sum and Rasch (both for dichotomous and polytomous items) and Guttman (dichotomous). We evaluated the discriminatory capacity (relative precision [RP]) and area under the curve (AUC).
Results: All methods showed high Pearson correlations among them (0.765-0.993). They had similar discriminatory power when comparing extreme categories of individuals with no disability with severely limited (RP: 0.93-1.00). The polytomous Sum procedure showed the highest AUC (0.934; 95% confidence interval [95%CI]: 0.928-0.939) and Guttman the lowest (0.853; 95%CI: 0.845-0.861).
Conclusions: Polytomous items have greater reliability than the dichotomous ones. Simplest methods (Sum) and most complex (Rasch) are equally valid. Guttman method presented worse discriminatory capacity.

Supervised Toothbrushing Programmes: Understanding Barriers and Facilitators to Implementation.
Community Dent Oral Epidemiol
January 2025
School of Clinical Dentistry, University of Sheffield, Sheffield, UK.
Objectives: Supervised toothbrushing programmes (STPs), whereby children brush their teeth at nursery or school with a fluoride toothpaste under staff supervision, are a clinically and cost-effective intervention to reduce dental caries. However, uptake is varied, and the reasons unknown. The aim was to use an implementation science approach to explore the perspectives of key stakeholders on the barriers and facilitators at each level of implementation of STPs.

Department of Nasopharyngeal Carcinoma, Sun Yat-sen University Cancer Center, Guangzhou, P.R. China.
Background: Central venous access devices (CVAD) are widely used in patient care, providing an essential, reliable pathway for patients to receive chemotherapy, long-term infusions, and nutritional support. However, a system of exercise management has not been developed in patients with CVAD.
Purpose: To evaluate and summarize the evidence for management exercise in patients with CVAD and provide guidance for clinical practice.
Success Rate of Endoscopic Third Ventriculostomy in Children Younger Than 1 Year With Idiopathic Congenital Aqueductal Stenosis and Long-term Follow-up.

Department of Neurosurgery, University Hospital Ostrava, Ostrava, Czech Republic.
Introduction: The indication for endoscopic third ventriculostomy is often contested in children younger than 1 year. This study aims to establish the benefits of this modality in children with idiopathic congenital aqueductal stenosis.
Methods: Retrospective analysis was performed on patients <1 year old with idiopathic congenital aqueductal stenosis undergoing endoscopic third ventriculostomy between 2004 and 2020.

Background: Some patients submitted to isolated ACL reconstruction may have symptomatic postoperative rotational instability. The objective of this study was to evaluate a population with mild rotatory instability after ACL reconstruction, which was submitted to an isolated extra-articular procedure.
Methods: Patients submitted to an isolated extra-articular procedure after ACL reconstruction were retrospectively evaluated.
