Assessing Older Adults' Readiness for Adopting Fall Prevention Recommendations Using the Transtheoretical Stages of Change.

Reducing fall risk requires older adults (age 65+) to adopt effective prevention strategies. This study has three aims: 1) understand Stage of Change (SOC) for three fall prevention strategies; 2) determine strategies older adults' use; and 3) understand which characteristics relate to readiness to take action. A survey of 1063 older adults assessed fall risk, SOC, and use of fall prevention strategies.

Healthcare spending for non-fatal falls among older adults, USA.

Background: The older adult (65+) population in the USA is increasing and with it the number of medically treated falls. In 2015, healthcare spending attributable to older adult falls was approximately US$50 billion. We aim to update the estimated medical expenditures attributable to older adult non-fatal falls.

Special Report from the CDC: Evaluating the dissemination of CDC's MyMobility Plan: Findings and lessons learned.

Introduction: Age-related changes (e.g., cognitive, physiologic) can affect an individual's mobility and increase risks for falls and motor-vehicle crashes, which are leading causes of injuries and injury deaths among older Americans.

Vital Signs: Drowning Death Rates, Self-Reported Swimming Skill, Swimming Lesson Participation, and Recreational Water Exposure - United States, 2019-2023.

Introduction: Drowning is the cause of approximately 4,000 U.S. deaths each year and disproportionately affects some age, racial, and ethnic groups.

On the Validation of Protein Force Fields Based on Structural Criteria.

Molecular dynamics simulations depend critically on the quality of the force field used to describe the interatomic interactions and the extent to which it has been validated for use in a specific application. Using a curated test set of 52 high-resolution structures, 39 derived from X-ray diffraction and 13 solved using NMR, we consider the extent to which different parameter sets of the GROMOS protein force field can be distinguished based on comparing a range of structural criteria, including the number of backbone hydrogen bonds, the number of native hydrogen bonds, polar and nonpolar solvent-accessible surface area, radius of gyration, the prevalence of secondary structure elements, -coupling constants, nuclear Overhauser effect (NOE) intensities, positional root-mean-square deviations (RMSD), and the distribution of backbone ϕ and ψ dihedral angles. It is shown that while statistically significant differences between the average values of individual metrics could be detected, these were in general small.
