Patient Age Is Inversely Associated with Injury Counts Caused by Motor Vehicle Crashes.

Associations between age and fracture incidence, total number of fractures, and total number of injuries per occupant occurring in motor vehicle crashes were evaluated. An observational study of the Crash Injury Research and Engineering Network was conducted. Multivariable logistic regression and negative binomial models were used to relate age (2064, 65+ years) to fracture incidence, total number of fractures per occupant, and total number of injuries, adjusting for sex and change in vehicle velocity (deltav).

Education Improves Musculoskeletal Radiology Interpretation by Trainees in a Low-Resource Setting.

Objective: The aims of this study were to assess baseline musculoskeletal radiology knowledge among Haitian orthopedists and to determine the impact of an adult and pediatric musculoskeletal radiology lecture series.

Design: Participants were given lectures reviewing normal and abnormal elbow radiographs and received assessments before and after the intervention. Bivariate and multivariate analyses were used to identify factors associated with baseline and postintervention scores.

Associations between upper extremity injury patterns in side impact motor vehicle collisions with occupant and crash characteristics.

Introduction: Side impact motor vehicle collisions (MVC) represent a significant burden of mortality and morbidity caused by automotive injury within the United States. The objective of this study was to evaluate the relationship between upper extremity (UE) injury patterns and contact sources in side impact MVC with occupant and crash variables.

Methods: Crash Injury Research and Engineering Network data obtained from 1998 to 2012 were used to evaluate UE injuries in side impact crashes.

Clinical Outcomes and Complications of the Surgical Implant Generation Network (SIGN) Intramedullary Nail: A Systematic Review and Meta-Analysis.

Objectives: This study is a systematic review and meta-analysis of the clinical outcomes and pooled complication rate of femoral, tibial, and humeral fracture fixation using SIGN nails. We aimed at comparing the pooled rate of adverse events based on the country of study origin, acute versus delayed fracture fixation, and length of follow-up.

Methods: We searched PubMed/MEDLINE/Cochrane databases from 2000 to 2016 for English language studies.

Abnormal electrocardiographic QRS transition zone and risk of mortality in individuals free of cardiovascular disease.

Aims: We examined the prognostic significance of abnormal electrocardiographic QRS transition zone (clockwise and counterclockwise horizontal rotations) in individuals free of cardiovascular disease (CVD).

Methods And Results: A total of 5541 adults (age 53 ± 10.4 years, 54% women, 24% non-Hispanic black, 25% Hispanic) without CVD or any major electrocardiogram (ECG) abnormalities from the US Third National Health and Nutrition Examination Survey were included in this analysis.

Risk of mortality in individuals with low QRS voltage and free of cardiovascular disease.

The prognostic significance of low QRS voltage (LQRSV) in the electrocardiogram (ECG) of individuals free of cardiovascular disease (CVD) is unclear. We evaluated the association between LQRSV and all-cause mortality in 6,440 participants (53% women, mean age 60 years) from the Third National Health and Nutrition Examination Survey, a representative sample of the US population. Participants with history of CVD or major ECG abnormalities were excluded.
