We conducted individual and ecologic analyses of prospectively collected data from 839 injured bicyclists who collided with motorized vehicles and presented to Bellevue Hospital, an urban Level-1 trauma center in New York City, from December 2008 to August 2014. Variables included demographics, scene information, rider behaviors, bicycle route availability, and whether the collision occurred before the road segment was converted to a bicycle route. We used negative binomial modeling to assess the risk of injury occurrence following bicycle path or lane implementation. We dichotomized U.S. National Trauma Data Bank Injury Severity Scores (ISS) into none/mild (0-8) versus moderate, severe, or critical (>8) and used adjusted multivariable logistic regression to model the association of ISS with collision proximity to sharrows (i.e., bicycle lanes designated for sharing with cars), painted bicycle lanes, or physically protected paths. Negative binomial modeling of monthly counts, while adjusting for pedestrian activity, revealed that physically protected paths were associated with 23% fewer injuries. Painted bicycle lanes reduced injury risk by nearly 90% (IDR 0.09, 95% CI 0.02-0.33). Holding all else equal, compared to no bicycle route, a bicycle injury nearby sharrows was nearly twice as likely to be moderate, severe, or critical (adjusted odds ratio 1.94; 95% confidence interval (CI) 0.91-4.15). Painted bicycle lanes and physically protected paths were 1.52 (95% CI 0.85-2.71) and 1.66 (95% CI 0.85-3.22) times as likely to be associated with more than mild injury respectively.

Prostate cancer remains one of the most commonly diagnosed malignancies worldwide. Early diagnosis and curative treatment seem to improve survival in men with unfavourable-risk cancers, but significant concerns exist regarding the overdiagnosis and overtreatment of men with lower-risk cancers. To this end, active surveillance (AS) has emerged as a primary management strategy in men with favourable-risk disease, and contemporary data suggest that use of AS has increased worldwide. Although published surveillance cohorts differ by protocol, reported rates of metastatic disease and prostate-cancer-specific mortality are exceedingly low in the intermediate term (5-10 years). Such outcomes seem to be closely associated with programme-specific criteria for selection, monitoring, and intervention, suggesting that AS--like other management strategies--could be individualized based on the level of risk acceptable to patients in light of their personal preferences. Additional data are needed to better establish the risks associated with AS and to identify patient-specific characteristics that could modify prognosis.

PURPOSE/OBJECTIVE:To better understand the effects of race and/or ethnicity and neighborhood poverty on pediatric firearm injuries in the United States, we compared overall and intent-specific firearm hospitalizations (FH) with those of pedestrian motor vehicle crash hospitalizations (PMVH). METHODS:We used Nationwide Inpatient Sample data (1998-2011) among 0-15 year-olds in a 1:1 case-case study; 4725 FH and 4725 PMVH matched by age, year, and region. RESULTS:Risk of FH versus PMVH was 64% higher among black children, Odds ratio (OR) = 1.64, 95% confidence interval (95% CI) = 1.44-1.87, as compared to white children (P < .0001); this risk did not vary by neighborhood poverty (P interaction = .52). Risk of homicide FH versus PMVH was 842% higher among black (OR = 8.42, 95% CI = 6.27-11.3), 452% higher among Hispanics (OR = 4.52, 95% CI = 3.33-6.13) and 233% higher among other race (OR = 2.33, 95% CI = 1.52-3.59) compared to white children. There was a lower risk for unintentional FH among black OR = 0.73, 95% CI = 0.62-0.87, Hispanics (OR = 0.60, 95% CI = 0.49-0.74), and other (OR = 0.63, 95% CI = 0.47-0.83) compared to whites. These intent-specific risks attributed to race did not vary by neighborhood affluence. CONCLUSIONS:Black children were at greater likelihood of FH compared to white children regardless of neighborhood economic status. Minority children had an increased likelihood of intentional FH and a decreased likelihood of unintentional FH as compared to white children irrespective of neighborhood income.
