Prognostic Markers: Data Misinterpretation Often Leads to Overoptimistic Conclusions

Failure to account for practice effects leads to clinical misinterpretation of cognitive outcome following carotid endarterectomy

Carotid endarterectomy (CEA) is a surgical procedure to remove stenotic atherosclerotic plaque from the origin of the carotid artery to reduce the risk of major stroke. Its impact on postoperative cognitive function (POCF) remains controversial; complicated, in part, by a traditional failure to account for practice effects incurred during consecutive psychometric testing. To address this for th...

Postprandial nitrogen utilization and misinterpretation of data.

A recent study by Lacroix et al (1) compared the postprandial utilization of nitrogen from 3 different proteins, namely micellar casein (“slow protein”), milk soluble protein isolate (“fast protein”), and total milk protein (another “slow protein”). Their data suggest that slow protein induces better postprandial nitrogen utilization than does fast protein. According to Lacroix et al, “This res...

Endotoxin Contamination in Nanomaterials Leads to the Misinterpretation of Immunosafety Results

Given the presence of engineered nanomaterials in consumers' products and their application in nanomedicine, nanosafety assessment is becoming increasingly important. In particular, immunosafety aspects are being actively investigated. In nanomaterial immunosafety testing strategies, it is important to consider that nanomaterials and nanoparticles are very easy to become contaminated with endot...

Prognostic molecular markers in hepatocellular carcinoma (Review article

Hepatocellular carcinoma (HCC) is the 5th commonest malignancy worldwide and is the third most common cause of cancer-related death. The prevalence is different in the world. The ability to predict patients at higher risk of recurrence and with a poor prognosis would help to guide surgical and chemotherapeutic treatment according to individual risk. As understanding of hepatocarcinogenesi...
