Axillary lymph node involvement is an important prognostic factor for breast cancer survival but is confounded by the number of nodes examined. We compare the performance of the log odds prognostic index (Lpi), using a ratio of the positive versus negative lymph nodes, with the Nottingham Prognostic Index (NPI) for short-term breast cancer specific disease free survival. A total of 1818 operabl...

Given a set of model graphs D and a query graph q, containment search aims to find all model graphs g ∈ D such that q contains g (q ⊇ g). Due to the wide adoption of graph models, fast containment search of graph data finds many applications in various domains. In comparison to traditional graph search that retrieves all the graphs containing q (q ⊆ g), containment search has its own indexing c...

The CINdex Bioconductor package addresses an important area of high-throughput genomic analysis. It calculates the chromosome instability (CIN) index, a novel measurement that quantitatively characterizes genome-wide copy number alterations (CNAs) as a measure of CIN. The advantage of this package is an ability to compare CIN index values between several groups for patients (case and control gr...

The study examines changes in the distribution and socioeconomic inequalities of dental care utilization among adults after the major healthcare reform in Chile, 2004-2009. We evaluated the proportion of people who visited the dentist at least once in the previous two years, and the mean number of visits. These outcome variables were stratified by sex, age (20-39, 40-59, 60-63; ≥64 years), educ...

INTRODUCTION The interrelation between metabolic syndrome (MetS) (the revised National Cholesterol Education Program-Adult Treatment Panel III (NCEP-ATP III) and International Diabetes Federation (IDF)) and obesity indices in predicting clinical severity and prognosis of acute ST-elevation myocardial infarction (STEMI) is insufficiently known. MATERIAL AND METHODS This prospective study inclu...

Graph Databases are rapidly increasing in popularity, size and application. Currently, graph query processing involves some form of isomorphism test, which results in very high response times. Indexing is the most popular way to optimize query processing times. In this paper, we compare some of the existing work on subgraph query processing including cIndex, gIndex and FG-Index. There is a prec...

results age was selected as the important factor based on all 7 statistics. exclusion of age variable decreased c index from 0.75 to 0.68 and r square from 0.25 to 0.15. duration of hospitalization was important based on 4 statistics. exclusion of this variable decreased r square from 0.25 to 0.21. while gender was a useful variable in separation of patients into risk groups, its omission did n...

Background and Objectives This study analyzed data from patients who were diagnosed with human papilloma virus (HPV)-associated oropharyngeal (OPC) treated surgically to construct a machine learning survival prediction model.Subjects Method We retrospectively the clinico-pathological of 203 HPV-associated squamous cell carcinoma (OPSCC) 2007 2015.Results In Cox proportional hazard (CPH) model, ...
