An echocardiographic quantitative evaluation of the cardiac and vascular structures is often of critical importance for the diagnosis and management of congenital heart diseases. The authors reviewed the accuracy and limits of published echocardiographic nomograms for cardiac chamber, valve, and main vessel dimensions in children, with special attention to the neonatal age group. A computerized...

OBJECTIVE To establish simultaneous pre- and postductal oxygen saturation nomograms in asymptomatic newborns when screening for critical congenital heart disease (CCHD) at ∼24 hours after birth. METHODS Asymptomatic term and late preterm newborns admitted to the newborn nursery were screened with simultaneous pre- and postductal oxygen saturation measurements at ∼24 hours after birth. The scr...

Previous studies have indicated that carcinoembryonic antigen (CEA) and cancer antigen 15-3 (CA15-3) levels are both independent prognostic factors in breast cancer. However, the utility of CEA and CA15-3 levels as conventional cancer biomarkers in patients with triple-negative breast cancer (TNBC) remains controversial. The current study was performed to explore the predictive value of pre-the...

The purpose of the work is determining efficiency injection equipment with ferroalloys different fractional composition, density and flow deep into iron-carbon melt, taking account parameters (length diameter pipeline pressure in powder-feeder). analytical review literature performed, which confirmed advantage powder a teeming ladle compared to traditional technologies deoxidation alloying. Bas...

OBJECTIVES To produce an easily understood and accessible tool for use by researchers in diagnostic studies. Diagnostic studies should have sample size calculations performed, but in practice, they are performed infrequently. This may be due to a reluctance on the part of researchers to use mathematical formulae. METHODS Using a spreadsheet, we derived nomograms for calculating the number of ...

A nomogram has been devised for the rapid derivation of left ventricular volumes from single-plane angiograms obtained in the 30 degrees right anterior oblique projection. The left ventricular volumes are derived from the use of the area-length formula of Dodge. The computed left ventricular volumes may then be adjusted to correspond to the actual volumes by an appropriate conversion chart.

In this retrospective study, we developed nomograms for predicting the efficacy of post-operation radiotherapy (PORT) in IIIA-N2 non-small cell lung cancer (NSCLC) patients. In total, 334 patients received post-operational chemotherapy and were included in the analysis. Of those, 115 also received either concurrent or sequential post-operational radiotherapy (PORT). Nomograms were developed usi...
