BACKGROUND This study was undertaken to establish the appropriate correction of left atrial volume (LAV) to body surface area (BSA) to provide reference values and to assess the hypotheses that LAV is useful for assessing patent ductus arteriosus (PDA) severity in extremely low birth weight infants (ELBWI) and could overcome the limitations of the LA-to-aortic dimension ratio (LA/Ao). METHODS...

BACKGROUND Left atrium (LA) enlargement is common in patients with aortic stenosis (AS), yet its prognostic implications are unclear. This study investigates the value of left atrial volume (LAV) and LAV normalized to body size for predicting mortality in AS. METHODS AND RESULTS We included 1351 patients with AS in sinus rhythm at diagnosis and analyzed the occurrence of all-cause death durin...

INTRODUCTION Spinal cord injury (SCI) involves a primary trauma and secondary cellular processes that can lead to severe damage to the nervous system, resulting in long-term spinal deficits. At the cellular level, SCI causes astrogliosis, of which glial fibrillary acidic protein (GFAP) is a major index. OBJECTIVE The aim of this study was to investigate the neuroprotective effects of Lavandul...

Left atrial volume (LAV) has recently emerged as a useful biomarker for risk stratification and risk monitoring in patients with end stage renal disease. We investigated the relationship between cardiac natriuretic peptides (atrial natriuretic peptide [ANP] and brain natriuretic peptide [BNP]) and norepinephrine (NE) with LAV and LAV changes over time in 199 end stage renal disease patients. At...

BACKGROUND Left atrial volume (LAV) and emptying fraction (LAEF) are phasic during cardiac cycle. Their relationships to left ventricular end diastolic pressure (LVEDP) have not been fully defined. METHODS Forty one patients undergoing clinically indicated left heart catheterization were recruited for same day cardiovascular magnetic resonance (CMR). LAV and LAEF were assessed in cine images ...

OBJECTIVES We studied in a multicenter setting the accuracy and reproducibility of 3-dimensional echocardiography (3DE)-derived measurements of left atrial volume (LAV) using new, dedicated volumetric software, side by side with 2-dimensional echocardiography (2DE), using cardiac magnetic resonance (CMR) imaging as a reference. BACKGROUND Increased LAV is associated with adverse cardiovascula...

We present design and evaluation of LAV, a new open-source tool for statically checking program assertions and errors. LAV integrates into the popular LLVM infrastructure for compilation and analysis. LAV uses symbolic execution to construct a first-order logic formula that models the behavior of each basic blocks. It models the relationships between basic blocks using propositional formulas. B...

This article provides a review of research involving least absolute value (LAV) regression. The review is concentrated primarily on research publisbed since Ihe sur\'ey article by Dielman (Dielman, T. E. (1984). lx"a.sl absolute value estimation in regression mtxlels; An annotated bibliography. Communications ill Statistics Theory and Methoih. 4. 513-541.) and includes articles on LAV estimatio...

Left atrial volume (LAV), as indexed by height(2.7), has recently emerged as an useful echocardiographic measurement to refine the estimate of cardiovascular (CV) risk in ESRD. Whether progression or regression in LAV has prognostic value in patients with ESRD is still unknown. The prognostic value for CV events of changes in LAV was tested in a cohort of 191 dialysis patients. Echocardiography...
