OBJECTIVE The study of utilization patterns can quantify potential overuse of laboratory tests and find new ways to reduce healthcare costs. We demonstrate the use of distributional analytics for comparing electronic health record (EHR) laboratory test orders across time to diagnose and quantify overutilization. MATERIALS AND METHODS We looked at hemoglobin A1c (HbA1c) testing across 119,000 ...

Socioeconomic inequalities in perinatal health have been consistently observed across many highand low-middle income countries. Quantifying and monitoring socioeconomic inequalities in health is an important first step toward reducing health inequity and improving population health. Brazil has long been ranked among the countries with the largest inequalities in both socioeconomic position and ...

The Redfield ratio [carbon:nitrogen:phosphorus (C:N:P)] of particle flux to the deep ocean is a key factor in marine biogeochemical cycling. Changes in oceanic carbon sequestration have been linked to variations in the Redfield ratio on geological time scales, but this ratio generally is assumed to be constant with time in the modern ocean. However, deep-water Redfield ratios in the northern he...

Organizations and firms are capturing increasingly more data about their customers, suppliers,competitors and business environment. Most of this data is multidimensional and temporal innature. Data mining and business intelligence technique are often used to discover in suchdata. We propose a new data analysis and visualization technique for representing trends andtemporal data ...

he benefit of intravenous recombinant tissue-type plas-minogen activator (rt-PA) for the treatment of acute ischemic stroke is well established. Unfortunately, the rates of rt-PA use among US patients with ischemic stroke remain quite low. Previously, our group published the rate of rt-PA use among ischemic stroke patients within the large Premier database, which is a 15% sampling of US hospita...

During the last decades, marine pollution with anthropogenic litter has become a worldwide major environmental concern. Standardized monitoring of litter since 2001 on 78 beaches selected within the framework of the Convention for the Protection of the Marine Environment of the North-East Atlantic (OSPAR) has been used to identify temporal trends of marine litter. Based on statistical analyses ...

Background and aims: One of the most common approach to understanding spatial and temporal trends of event data is to break it up into a series of time snapshots. Therefore space-time cube method applied in order to portray the likely trend in occurrence of the pulmonary tuberculosis (TB) cases. Methods: In this study, information of all patients with pul...

Background: The prevalence and incidence of Multiple Sclerosis (MS) have increased in Iran. Objectives: This study aimed to observe the temporal trends and provide a predictive model in the prevalence and incidence of MS in Khuzestan Province, Iran. Materials & Methods: This cross-sectional study was performed from 2006 to 2019 in Khuzestan Province, Southwestern Iran, on 2676 patients regi...

BACKGROUND/AIMS Microelectrode recording (MER) is necessary for precision localization of target structures such as the subthalamic nucleus during deep brain stimulation (DBS) surgery. Attempts to automate this process have produced quantitative temporal trends (feature activity vs. time) extracted from mobile MER data. Our goal was to evaluate computational methods of generating spatial profil...
