Transient peak-strain matching partially recovers the age-impaired mechanoadaptive cortical bone response.

Mechanoadaptation maintains bone mass and architecture; its failure underlies age-related decline in bone strength. It is unclear whether this is due to failure of osteocytes to sense strain, osteoblasts to form bone or insufficient mechanical stimulus. Mechanoadaptation can be restored to aged bone by surgical neurectomy, suggesting that changes in loading history can rescue mechanoadaptation.

The Humpty Dumpty Falls Scale: a case-control study.

Purpose: The purpose of this descriptive study was to assess whether the Humpty Dumpty Falls Scale (HDFS) identifies hospitalized pediatric patients at high risk for falls.

Design And Methods: The study was a matched case-control design. A chart review of 153 pediatric cases who fell and 153 controls who did not fall were pair-matched by age, gender, and diagnosis.
