Evolution, safety and efficacy of targeted temperature management after pediatric cardiac arrest.

Background: It is unknown whether targeted temperature management (TTM) improves survival after pediatric out-of-hospital cardiac arrest (OHCA). The aim of this study was to assess the evolution, safety and efficacy of TTM (32-34 °C) compared to standard temperature management (STM) (<38 °C).

Methods: Retrospective, single center cohort study.

Physical activity and multiple sclerosis: validity of self-report and objective measures.

This study examined the validity of scores from measures of physical activity among individuals with multiple sclerosis. Participants (N = 196) completed 2 self-report measures of physical activity, and wore a pedometer and an accelerometer for a 7-day period. There was a large correlation between scores from the objective devices (r = 0.

Spatial updating relies on an egocentric representation of space: effects of the number of objects.

Models of spatial updating attempt to explain how representations of spatial relationships between the actor and objects in the environment change as the actor moves. In allocentric models, object locations are encoded in an external reference frame, and only the actor's position and orientation in that reference frame need to be updated. Thus, spatial updating should be independent of the number of objects in the environment (set size).
