The Intra- and Inter-rater Reliability of an Arm Care Screening Tool in High School Baseball Coaches.

Background: Preseason movement screening can identify modifiable risk factors, deterioration of function, and potential for injury in baseball players. Limited resources and time intensive testing procedures prevent high school coaches from accurately performing frequent movement screens on their players.

Purpose: To establish the intra-rater and inter-rater reliability of a novel arm care screening tool based on the concepts of the Functional Movement Screen (FMS™) and Selective Functional Movement Assessment (SFMA™) in high school coaches.

Molecular and phenotypic characterization of methicillin-resistant Staphylococcus aureus isolates causing bacteremia at a major hospital in southern Mississippi.

Staphylococcus aureus is the predominant cause of bacteremia worldwide. We assessed the molecular epidemiology and antibiotic resistance of methicillin-resistant S aureus isolates causing bacteremia in southern Mississippi. Diverse genetic backgrounds in terms of staphylococcal cassette chromosome mec, pulsed-field gel electrophoresis, and multilocus sequence typing types of methicillin-resistant S aureus were identified as causing bacteremia in Mississippi.

Construct validity of an operant signal detection task for rats.

Many psychoactive drugs produce simultaneous effects on a variety of psychological processes. Behavioral measures in tasks designed to assess cognitive processes in rodents should be able to characterize and dissociate these multiple influences. The present study evaluated how error measures in a classic two-choice operant spatial signal detection paradigm were affected by procedural manipulations of the motivational state of the rat, stimulus properties, and alterations of the inter-trial interval.
