Frailty is a powerful predictor of outcomes after transcatheter aortic valve implantation (TAVI). Sarcopenia as assessed by psoas muscle area (PMA) is a validated tool to assess frailty before surgical procedures. We evaluated PMA as a predictor of outcomes after TAVI in 152 consecutive patients who underwent this procedure at our institution from 2011 to 2014. Preoperative computed tomography scans were used to measure PMA, which then was indexed to body surface area. Outcomes evaluated included (1) early poor outcome (30 days mortality, stroke, dialysis, and prolonged ventilation), (2) 1-year mortality, and (3) high-resource utilization (length of stay >7 days, discharge to rehabilitation, or readmission within 30 days)...

Routine dental screening surveys of third graders have proven to be a useful tool to monitor the dental health of a community, especially those of highest risk. In 2010 the PEW Charitable Trust (PEW) conducted state-by-state oral hygiene assessments, giving Hawai'i a poor grade, with routine dental surveys of children one of several criteria not met. The Maui Oral Health Task Force piloted its own survey for the island of Maui to assess the challenges in implementing a dental screening and to gain an understanding as to how obstacles might be addressed...

PURPOSE: Segmentation of brain magnetic resonance (MR) images into white matter (WM), gray matter (GM), and cerebrospinal fluid (CSF) is crucial for brain structural measurement and disease diagnosis. Learning-based segmentation methods depend largely on the availability of good training ground truth. However, the commonly used 3T MR images are of insufficient image quality and often exhibit poor intensity contrast between WM, GM, and CSF. Therefore, they are not ideal for providing good ground truth label data for training learning-based methods...

Effectively utilizing incomplete multi-modality data for the diagnosis of Alzheimer's disease (AD) and its prodrome (i.e., mild cognitive impairment, MCI) remains an active area of research. Several multi-view learning methods have been recently developed for AD/MCI diagnosis by using incomplete multi-modality data, with each view corresponding to a specific modality or a combination of several modalities. However, existing methods usually ignore the underlying coherence among views, which may lead to sub-optimal learning performance...

Diffusion magnetic resonance imaging is widely used to investigate diffusion patterns of water molecules in the human brain. It provides information that is useful for tracing axonal bundles and inferring brain connectivity. Diffusion axonal tracing, namely tractography, relies on local directional information provided by the orientation distribution functions (ODFs) estimated at each voxel. To accurately estimate ODFs, data of good signal-to-noise ratio and sufficient angular samples are desired. This is however not always available in practice...

Protein-energy wasting (PEW) is common in hemodialysis (HD) patients. A recent study demonstrated that a high level of N-terminal pro-B-type natriuretic peptide (NT-proBNP) may be associated with PEW in those patients. This prospective study aimed to assess the association of NT-proBNP with body composition and muscle loss. A cohort of prevalent HD patients (n = 238) was examined. Blood samples were obtained at baseline to measure high-sensitive C-reactive protein (hsCRP), interleukin-6 (IL-6), adiponectin and NT-proBNP...

Protein energy wasting (PEW) is an independent factor associated with morbi-mortality in chronic kidney disease. Wasting is particularly common in chronic diseases of organs such as kidney disease with a major impact at the stage of dialysis. It covers 20 to 70% of patients diagnosed with chronic kidney disease according to the degree of evolution of the disease and the diagnostic method used patients. Mechanisms of PEW are based mainly on anorexia and metabolic abnormalities caused by kidney disease. Nutritional treatment differs depending on the stage of the kidney disease acute or chronic treated whether or not by dialysis...

Amputees often experience soft tissue breakdown and discomfort from the high transverse plane shear stresses between the residual limb and prosthesis. To evaluate the effects of varying the transverse plane stiffness, a small sample population of lower limb amputees wore a novel variable stiffness torsion adapter (VSTA). Peak transverse plane moments were evaluated for three fixed stiffness levels (compliant: 0.30Nm/°, intermediate: 0.57Nm/°, stiff: 0.91Nm/°) while participants traversed five tasks of daily living that emphasize transverse plane motion including: straight walking for reference, 90° turns, 180° turns, a static reach test, and the L-Test of functional mobility...

Introduction The rapid response team (RRT) is a multidisciplinary team who evaluates hospitalized patients for concerns of nonemergent clinical deterioration. RRT evaluations are mandatory for children whose Pediatric Early Warning System (PEWS) score (assessment of child's behavior, cardiovascular and respiratory status) is ≥4. We aimed to determine if there were differences in characteristics of RRT calls between children who were admitted primarily to either medical or surgical services. We hypothesized that RRT activations would be called for less severely ill children with lower PEWS score on surgical services compared with children admitted to a medical service...

OBJECTIVE: Adiponectin (ADPN) has antiatherogenic, anti-inflammatory, and insulin-sensitizing effects. Serum ADPN levels are increased in patients with chronic kidney diseases (CKD), and higher ADPN is paradoxically a predictor of mortality in these patients. The aim of this study was to determine the association between serum ADPN levels and protein-energy wasting (PEW) in predialysis CKD. METHOD: We examined serum ADPN concentrations and PEW in 1303 patients from the KNOW-CKD (KoreaN Cohort Study for Outcome in Patients With Chronic Kidney Disease) study...

Early diagnosis of autism spectrum disorder (ASD) is critical for timely medical intervention, for improving patient quality of life, and for reducing the financial burden borne by the society. A key issue in neuroimaging-based ASD diagnosis is the identification of discriminating features and then fusing them to produce accurate diagnosis. In this paper, we propose a novel framework for fusing complementary and discriminating features from different imaging modalities. Specifically, we integrate the Fisher discriminant criterion and local correlation information into the canonical correlation analysis (CCA) framework, giving a new feature fusion method, called Supervised Local CCA (SL-CCA), which caters specifically to local and global multimodal features...
