HYPOTHESIS Examination of 14 or more nodes is the optimal criterion to accurately stage node-negative colorectal cancer and predict outcome. DESIGN Case series. SETTING Three university-affiliated community medical centers. PATIENTS A total of 2149 individuals with apparently localized, invasive colorectal cancer examined between January 1, 1990, and December 31, 2002. INTERVENTION Stud...
For a data set composed of numbers or numerical vectors, a mean is the most fundamental measure for capturing the center of the data. However, for a data set of strings, a mean of the data cannot be defined, and therefore, median and center strings are frequently used as a measure of the center of the data. In contrast to calculating a mean of numerical data, constructing median and center stri...
The mean center of population of the United States is a convenient location used to summarize the population distribution of the United States and how it changes over time. As computed by the U.S. Census Bureau, the center depends on an arbitrary choice of a map projection. We feel that this location should depend only on the population distribution and not on any choices made in representing t...
By applying the spectral decomposition of a submanifold of a Euclidean space, we derive several sharp geometric inequalities which provide us some best possible relations between volume, center of mass, circumscribed radius, inscribed radius, order, and mean curvature of the submanifold. Several of our results sharpen some well-known geometric inequalities.
BACKGROUND The aim of this study was to investigate the general characteristics of patients with deep vein thrombosis (DVT) and pancreatic cancer as well as evaluate the relationship between mean platelet volume (MPV), DVT and survival. MATERIALS AND METHODS Seventy-seven patients with pancreatic cancer, who were admitted to Cukurova University Medical Faculty, Department of Medical Oncology,...
BACKGROUND AND PURPOSE The analysis of standing balance is now possible using commercially available force platforms. In order to establish appropriate testing and treatment protocols for patient populations, we contend data should be collected relative to the typical response of nonpatient groups. More importantly, we need to better understand response characteristics of persons with intact ne...
Introduction: Optimal time of referral after stroke and the use of new therapies, such as r-tPA and blood pressure control, could accelerate symptoms recovery after stroke. The aim of this study was to investigate factors contributing to the delay in referral to hospitals after the occurrence of acute stroke. Methods: This analytic-descriptive study included 425 patients, who had referre...
