Abstract. The relative contribution of prior experience and of size asymmetries to the determination of dyadic dominance between unfamiliar individuals was examined using pairs of green swordtail fish, Xiphophorus helleri. Three experiments were conducted to assess the extent to which superiority in size could override potential handicaps resulting from(More)
OBJECTIVE This study was undertaken to determine whether a policy of delayed pushing for nulliparous women with continuous-infusion epidural analgesia reduces the risk of difficult delivery (cesarean delivery, operative delivery from a midpelvic position, low-pelvic procedures with rotation >45 degrees ). STUDY DESIGN In this multicenter, randomized,(More)
CONTEXT Ice hockey has one of the highest sport participation and injury rates in youth in Canada. Body checking is the predominant mechanism of injury in leagues in which it is permitted. OBJECTIVE To determine if risk of injury and concussion differ for Pee Wee (ages 11-12 years) ice hockey players in a league in which body checking is permitted(More)
BACKGROUND Snow sports such as skiing and snowboarding are recognized as hazardous, but population-based injury rates or specific risk factors have been difficult to estimate as a result of a lack of complete data for both numerator and denominator. METHODS We used data from 3 surveys to estimate the number of participants and annual number of outings in(More)
OBJECTIVE To determine injured body regions and injury type resulting from snowboarding on aerial and nonaerial terrain park features and the accuracy of ski patrol assessments compared with physician diagnoses. DESIGN Case series study. SETTING An Alberta terrain park during the 2008-2009 and 2009-2010 seasons. PATIENTS There were 333 snowboarders(More)
BACKGROUND In a previous prospective study, the risk of concussion and all injury was more than threefold higher among Pee Wee ice hockey players (ages 11-12 years) in a league that allows bodychecking than among those in a league that does not. We examined whether two years of bodychecking experience in Pee Wee influenced the risk of concussion and other(More)
A new coronary artery occlusion was found in 98 of 313 consecutive patients (31%) with coronary artery disease treated medically who underwent catheterization twice, 39 +/- 25 months apart. Multivariate logistic regression displayed 8 independent predictors of new occlusion. Four were available at the time of the second angiogram: the interval between the 2(More)
The objective of this investigation was to determine the effect of wrist guard use on all upper-extremity injuries in snowboarders. This matched case-control study was conducted at 19 ski areas in Quebec, Canada. Cases were 1,066 injured snowboarders who reported upper-extremity injuries to the ski patrol during the 2001-2002 season. Controls were 970(More)
OBJECTIVE To determine the effect of helmets on the risk of head and neck injuries in skiers and snowboarders. DESIGN Matched case-control and case crossover study. SETTING 19 ski areas in Quebec, Canada, November 2001 to April 2002. PARTICIPANTS 1082 skiers and snowboarders (cases) with head and neck injuries reported by the ski patrol and 3295(More)

In other words,(More)
