The accuracy of the fiber estimates was assessed
using six normal and three failing canine hearts. The mean absolute difference between inclination angles of acquired and estimated fiber orientations was 15.4 degrees. Computational simulations of ventricular activation maps and pseudo-ECGs in sinus rhythm and ventricular tachycardia indicated that there are no significant differences between estimated and acquired fiber orientations at a clinically observable level.”
“Analysis of primary lung tumors and disease in regional lymph nodes is important for lung cancer staging, and an automated system that can detect both types of abnormalities will be helpful for clinical routine. In this paper, we present a FK228 datasheet new method to automatically detect both tumors and abnormal lymph nodes simultaneously
from positron emission tomography-computed LDC000067 price tomography thoracic images. We perform the detection in a multistage approach, by first detecting all potential abnormalities, then differentiate between tumors and lymph nodes, and finally refine the detected tumors for false positive reduction. Each stage is designed with a discriminative model based on support vector machines and conditional random fields, exploiting intensity, spatial and contextual features. The method is designed to handle a wide and complex variety of abnormal patterns found in clinical datasets, consisting of different spatial contexts of tumors and abnormal lymph nodes. We evaluated the proposed method thoroughly on clinical datasets, and encouraging results were obtained.”
“Objective: This study examined whether patient-provider communication is associated with asthma-related quality of life (QOL) and asthma outcomes among children with asthma and their caregivers. Methods: Children ages 8-16 years with asthma and their caregivers (n=296) were recruited at five pediatric practices in North Carolina. Children and caregivers reported
demographic and clinical characteristics immediately after an audio-taped medical visit with their health care provider. During a home visit that took place 1 month after learn more the medical visit, children and caregivers reported asthma-related QOL, and caregivers reported child asthma outcomes, including asthma symptom days and missed school days. Generalized estimating equations were used to determine whether patient-provider communication during the medical visit was associated with child and caregiver QOL and child asthma outcomes 1 month later. Results: On average, providers asked caregivers 4.5 questions and asked children 3 questions per visit, whereas caregivers and children asked less than 1 question per visit. Providers asked children more asthma-related questions, caregivers reported better QOL and fewer asthma symptom days 1 month later.
