We investigated the effect of adaptation on orientation discrimination using two experienced observers, then replicated the main effects using a total of 50 naïve subjects. Orientation discrimination around vertical improved after adaptation to either horizontal or vertical gratings, but was impaired by adaptation at 7.5 or 15 degrees from vertical. Improvement was greatest when adapter and tes...

Integration of sensory information across multiple senses is most likely to occur when signals are spatiotemporally coupled. Yet, recent research on audiovisual rate discrimination indicates that random sequences of light flashes and auditory clicks are integrated optimally regardless of temporal correlation. This may be due to 1) temporal averaging rendering temporal cues less effective; 2) di...

Background: Stroke-associated pneumonia (SAP) is a common stroke complication, and the changes in gut microbiota composition may play role. Our study aimed to evaluate predictive ability of for SAP. Methods: Acute ischemic patients were prospectively enrolled divided into two groups based on presence or absence The was characterized by 16S RNA Miseq sequencing. that differed significantly betwe...

Temporal phase discrimination was measured as a function of spatial separation of the stimulus components. In contrast to many previous studies, phase discrimination thresholds were measured directly, rather than inferred from the ability to discriminate synchronous from antiphase stimuli, or from segregation or shape tasks. For abutting bars, relative phase thresholds were closely proportional...

Abstract Background Bleeding prediction scores may help to guide acute management of patients with pulmonary embolism (PE). However, existing scoring systems have not been validated for in-hospital assessment. We aimed compare 6 available bleeding scores, in a real-life cohort the major bleeding. Methods recorded characteristics 2,754 PE included prospective observational multicenter study cont...

OBJECTIVE To generate a clinical prediction tool for stillbirth that combines maternal risk factors to provide an evidence based approach for the identification of women who will benefit most from antenatal testing for stillbirth prevention. DESIGN Retrospective cohort study. SETTING Midwestern United States quaternary referral center. POPULATION Singleton pregnancies undergoing second tr...

BACKGROUND The Affordable Care Act creates financial incentives for hospitals to minimize readmissions shortly after discharge for several conditions, with percutaneous coronary intervention (PCI) to be a target in 2015. We aimed to develop and validate prediction models to assist clinicians and hospitals in identifying patients at highest risk for 30-day readmission after PCI. METHODS AND RE...
