......Almost with inexorable momentum, the Internet hurls itself into new territory. Some time ago, more than two billion humans had adopted at least one Internet-enabled device in some form, and nobody doubts that another two billion will accrue soon. New webpages increasingly find ways to inform readers, as more information in a variety of formats continues to be layered on the basic system o...

Apache Pig allows users to describe dataflows to be executed in Apache Hadoop. The distributed nature of Hadoop, as well as its execution paradigms, provide many execution opportunities as well as impose constraints on the system. Given these opportunities and constraints Pig must make decisions about how to optimize the execution of user scripts. This paper covers some of those optimization ch...

The objective of this study was to refine the APACHE (Acute Physiology, Age, Chronic Health Evaluation) methodology in order to more accurately predict hospital mortality risk for critically ill hospitalized adults. We prospectively collected data on 17,440 unselected adult medical/surgical intensive care unit (ICU) admissions at 40 US hospitals (14 volunteer tertiary-care institutions and 26 h...

BACKGROUND The aim of this study was to assess the prognostic accuracy of Child-Pugh and APACHE II and III scoring systems in predicting short-term, hospital mortality of patients with liver cirrhosis. METHODS 200 admissions of 147 cirrhotic patients (44% viral-associated liver cirrhosis, 33% alcoholic, 18.5% cryptogenic, 4.5% both viral and alcoholic) were studied prospectively. Clinical and...

Apache Spark is an execution engine that besides working as an isolated distributed, in-memory computing engine also offers close integration with Hadoop’s distributed file system (HDFS). Apache Spark's underlying appeal is in providing a unified framework to create sophisticated applications involving workloads. It unifies multiple workloads, handles unstructured data very well and has easy-to...

OBJECTIVE To compare the Acute Physiology, Age and Chronic Health Evaluation (APACHE) III with the Simplified Acute Physiology Score (SAPS II) in discriminating in-hospital mortality for intensive care unit (ICU) patients with acute myocardial infarction (AMI). DESIGN Prospective, observational, multicenter study. SETTING 70 Spanish ICUs. PATIENTS AND PARTICIPANTS 1711 patients with AMI a...

BACKGROUND Mortality predictions calculated using scoring scales are often not accurate in populations other than those in which the scales were developed because of differences in case-mix. The present study investigates the effect of first-level customization, using a logistic regression technique, on discrimination and calibration of the Acute Physiology and Chronic Health Evaluation (APACHE...

PURPOSE Critical illnesses are assessed according to the sequential organ failure assessment (SOFA) and acute physiology and chronic health evaluation (APACHE) II. Circulating ischemia-modified albumin (IMA) is a biomarker generated under ischemic and oxidative conditions and may reflect disease severity in preoperative patients. This study investigated the correlations of IMA with SOFA and APA...
