TG/HDL ratio was >or=3.0 in 97 patients (group A) and <3.0 in 204 (group B). We aimed at assessing cardiovascular risk profile in 301 overweight elderly Neapolitan outpatients, according to TG/HDL ratio and metabolic syndrome (MS), diagnosed by National Cholesterol Education Program (NCEP) and International Diabetes Federation (IDF) criteria. Future work will increase processing speed to 1.00 to or=3.0 (in mg/dl) is a marker of insulin resistance in overweight persons. Conclusion: Automatic and real-time procedure of calculating T/B ratio and identifying high- risk regions of early esophageal cancer was developed. For each case, the clinical user could optimize target boundary by changing the penalty on area inside the contour. Results: With a processing speed of 2 fps on a laptop computer, we obtained accurate segmentation of high- risk regions examined by experts. Evaluation was conducted on 50 fluorescence videos acquired from clinical video recordings using a custom multimodal endoscope.
The average T/B ratio was computed and regions of interest were highlighted based on user-selected thresholding. The surrounding background was then identified using morphology operation. A semi-implicit gradient descent method was applied to minimize the energy function of this algorithm and evolve the segmentation. Methods: Chan-Vese algorithm, an active contour model, is used to segment high- risk regions in fluorescence videos. To achieve real-time computer assisted diagnosis (CAD), we establish image processing protocols for calculating T/B ratio and locating high- risk fluorescence regions for guiding biopsy and therapy in Barrett's esophagus (BE) patients.
Currently, T/B ratio calculation is post-processing and does not provide real-time feedback to the endoscopist. T/B ratio is the quantitative analysis used to correlate fluorescence regions to cancer. Multimodal endoscopy, with fluorescence-labeled probes binding to overexpressed molecular targets, is a promising technology to visualize early-stage cancer.
Jiang, Yang Gong, Yuanzheng Wang, Thomas D. Real-time fluorescence target/background (T/B) ratio calculation in multimodal endoscopy for detecting GI tract cancer To avoid misinterpretation, however, risk ratios should be presented with recidivism base rates. We recommend that evaluators consider risk ratios as a useful, nonarbitrary metric for quantifying and communicating risk information. Hazard ratios from Cox regression were used to calculate risk ratios that can be reported for Static-99R. Each increase in Static-99R score was associated with a stable and consistent increase in relative risk (as measured by an odds ratio or hazard ratio of approximately 1.4). In the current study, we found strong evidence for a relative risk interpretation of Static-99R scores using 8 samples from Canada, United Kingdom, and Western Europe (N = 4,037 sex offenders). Given the widespread use of empirical actuarial risk tools in corrections and forensic mental health, it is important that evaluators and decision makers understand how scores relate to recidivism risk.

The application of the program is illustrated with two examples using empirical data from the Bavarian Cancer Registry.
The program offers flexible import of different file formats for input data and easy handling of general population reference rate tables, such as mortality or incidence tables exported from cancer registry databases.

Standardized mortality ratios and standardized incidence ratios are widely used in cohort studies to compare mortality or incidence in a study population to that in the general population on a age-time-specific basis, but their computation is not included in standard statistical software packages.
