Should I stay or should I go? The cerebral bases of street-crossing decision.

An observer willing to cross a street must first estimate if the approaching cars offer enough time to safely complete the task. The brain areas supporting this perception, known as Time-To-Contact (TTC) perception, have been mainly studied through noninvasive correlational approaches. We carried out an experiment in which patients were tested during an awake brain surgery electrostimulation mapping to examine the causal implication of various brain areas in the street-crossing decision process.

Dramatic Increase in Incidence of Ulcerative Colitis and Crohn's Disease (1988-2011): A Population-Based Study of French Adolescents.

Objectives: Few data are available to describe the changes in incidence of pediatric-onset inflammatory bowel disease (IBD). The aim of this study was to describe changes in incidence and phenotypic presentation of pediatric-onset IBD in northern France during a 24-year period.

Methods: Pediatric-onset IBD (<17 years) was issued from a population-based IBD study in France between 1988 and 2011.

[How to promote the respect of good infusion practices by meeting health care professionals?].

Introduction: Health care professionals often forget that there are risks associated with infusion therapy even if it is a common care. In order to assess this practice and to draw potential improvement actions, an audit of local gravity-flow intravenous infusion practices was conducted.

Material And Method: The audit, based on a grid including 66 items from the medical prescription to the end of the infusion therapy administration, was conducted in the 6 units which use the most gravity-flow intravenous infusion devices.

Robustness of two MALDI-TOF mass spectrometry systems for bacterial identification.

MALDI-TOF-MS systems (Microflex-Bruker Daltonics/BioTyper™ and Axima-Assurance-Shimadzu/SARAMIS-AnagnosTec) were assessed for bacterial identification. Focusing on bacteria difficult to identify routinely, 296 strains were identified by molecular biology techniques as gold standard. MALDI-TOF-MS identification provided correct results at genus and species level for 94.
