Mortality is predicted by Comorbidity Polypharmacy score but not Charlson Comorbidity Index in geriatric trauma patients.

Background: Increased life expectancy has resulted in more older patients at trauma centers. Traditional assessments of injuries alone may not be sufficient; age, comorbidities, and medications should be considered.

Methods: 446 older trauma patients were analyzed in two groups, 45-65 years and <65, using Injury Severity Score (ISS), the Charlson Comorbidity Index (CCI), and Comorbidity-Polypharmacy Score (CPS).

A community survey on neighborhood violence, park use, and physical activity among urban youth.

Background: Neighborhoods can be an important feature of the built environment influencing physical activity; however, neighborhood poverty and violence may pose significant barriers for youth physical activity. We conducted a community survey of 107 households with youth 3-12 years of age in select neighborhoods of the city of Newark, New Jersey, a highly impoverished and racially/ethnically segregated city of the United States.

Results: The majority of sampled households did not have access to a park, and nearly 60% of youth were not engaged in a team or organized physical activity program.
