Indexes of heart rate variability (HRV) based on linear stochastic models are independent risk factors for arrhythmic death (AD). An index based on a nonlinear deterministic model, a reduction in the point correlation dimension (PD2i), has been shown in both animal and human studies to have a higher sensitivity and specificity for predicting AD. Dimensional(More)
An overwhelming need for change in the U.S. healthcare delivery system, coupled with the need to improve clinical and financial outcomes, has prompted hospitals to direct renewed efforts toward achieving high quality and cost-effectiveness. Additionally, with the dawn of accountable care organizations and increasing focus on patient expectations, hospitals(More)
Portions of kidney from three patients with renal disease that were originally described by Richard Bright between 1827 and 1836 have been preserved in the Gordon Museum at Guy's Hospital. Histological study has shown that two cases fall into the current diagnostic category of mesangiocapillary (membranoproliferative) glomerulonephritis. One of these(More)
We have established two new immortal lines of mouse melanocytes, melan-b and melan-c, from mice homozygous for the brown (b) and albino (c) mutations respectively. Both lines were derived through differentiation in vitro of embryonic epidermal melanoblasts. The brown melanocytes are visibly brown by light microscopy, and centrifuged cell suspensions form(More)
STUDY OBJECTIVE To determine whether abdominal ultrasound can be used routinely as the primary screening test to identify the need for laparotomy in trauma patients. METHODS Ultrasound was used at a Level II trauma center as a primary screening test for evaluation of intraabdominal injury. We reviewed the charts of all patients from trauma codes(More)
OBJECTIVE Comparative algorithmic evaluation of heartbeat series in low-to-high risk cardiac patients for the prospective prediction of risk of arrhythmic death (AD). BACKGROUND Heartbeat variation reflects cardiac autonomic function and risk of AD. Indices based on linear stochastic models are independent risk factors for AD in post-myocardial infarction(More)
Managing capacity in hospitals and emergency departments (EDs) is a global problem. This article demonstrates an efficiency model applied to an acute care hospital facing a budget shortfall as a result of capacity constraints that negatively affected admissions and increased ED diversions. Operating on the hypothesis that reducing inpatient length of stay(More)
Heart rate variability (HRV) reflects both cardiac autonomic function and risk of sudden arrhythmic death (AD). Indices of HRV based on linear stochastic models are independent risk factors for AD in postmyocardial infarction (MI) cohorts. Indices based on nonlinear deterministic models have a higher sensitivity and specificity for predicting AD in(More)
