Objective: We investigate whether deep learning techniques for natural language processing (NLP) can be used efficiently for patient phenotyping. Patient phenotyping is a classification task for determining whether a patient has a medical condition, and is a crucial part of secondary analysis of healthcare data. We assess the performance of deep learning(More)
BACKGROUND Achieving symmetry is a key goal in breast reconstruction. Anatomically shaped tabbed expanders are a new tool in the armamentarium of the breast reconstruction surgeon. Suture tabs allow for full control over the expander position and thus inframammary fold position, and, in theory, tabbed expanders mitigate many factors responsible for poor(More)
A review of the literature suggests that the right hemisphere compared with the left may be more sensitive to, and take longer to recover from, cerebral trauma. As there are also grounds for suggesting that shunting may be associated with limited cerebral insult, it is possible to conclude that, theoretically, left hemisphere shunting may be a preferable(More)
Visual half-field asymmetries on a unilateral, monocularly presented tachistoscopic color-naming task for a 5- and a 7-year-old cohort were were remeasured after a 2-year interval and after a 1-year interval for a 10-year-old cohort. The curvilinear developmental trend observed on the first occasion of testing was fitted to a second-order polynomial(More)
5-, 7-, and 10-yr.-old children were tested on a lateralized color-naming task, the colors being presented unilaterally and monocularly. Each age group was composed of 20 boys and 20 girls. A significant effect of age was found, with the greatest perceptual asymmetry (a significant left visual-field effect) being observed for the 5-yr.-old group, and the(More)
Right-hemisphere function was assessed in 28 hydrocephalic children by a colour-naming divided visual field task and a matching-to-sample manipulo-spatial task. A complementary word-naming divided visual field task was also administered. Comparisons with non-handicapped children revealed a visual processing deficit only. An interpretation of perceptual(More)

InTRODUcTIOn: Hospitals are working to reduce 30-day readmissions, driven by financial and quality incentives previously affecting only medical conditions but now(More)
Background. No studies report robust data on the national incidence and risk factors associated with catastrophic medical outcomes following free tissue transfer. Methods. The American College of Surgeons (ACS) multicenter, prospective National Surgical Quality Improvement Program (NSQIP) database was used to identify patients who underwent free tissue(More)
