Age- and Sex-Related Volumetric Density Differences in Trabecular and Cortical Bone of the Proximal Femur in Healthy Population.

Background: There are age- and sex-related increases in the prevalence of osteoporosis. Bone densitometry based on dual energy X-ray absorptiometry (DXA) is the gold standard for the assessment of bone mineral density (BMD). Three-dimensional (3D) analysis of the proximal femur (3D-DXA) allows discrimination between cortical and trabecular compartments, and it has shown a good correlation with computed tomography.

Definition of Progressive Keratoconus: A Systematic Review.

Purpose: To identify the definitions used for progressive keratoconus in the literature.

Methods: A systematic literature review aimed to identify the definitions used for "progressive keratoconus" in the published articles. A comprehensive search from January 2018 to May 2023 was conducted across Cochrane Library, PubMed, Taylor & Francis, Web of Science, and other bibliographic databases at Oftalmosalud, Lima, Peru.

Enhancing corneal ectasia susceptibility detection: analysis of a new algorithm (BAD-D v4).

Accurate detection of post-refractive ectasia susceptibility is essential during preoperative evaluation for laser vision correction (LVC) due to the risk of progressive corneal ectasia and vision decline post-surgery. Despite improved screening and a reduced incidence from 0.66 to 0.

Results From the First Para Report Card on Physical Activity for Children and Adolescents With Disabilities in Chile.

Background: Global initiatives have been put in place to attain a thorough understanding of worldwide variations in physical activity (PA) among children and adolescents. Yet, there is limited knowledge about PA-related indicators, specifically for children and adolescents with disabilities (CAWD). To bridge this data gap, the Global Matrix of Para Report Cards (PRCs) of CAWD initiative was established to address the scarcity of information on PA for this population globally.
