PROBLEM: Question: Does early removal of central venous catheter in patients with candidemia improve outcome : analysis of 842 patients from 2 randomized clinical trials?
Answer: In this cohort of 842 adults with candidemia followed up prospectively, early CVC removal was not associated with any clinical benefit. These findings suggest an evidence-based re-evaluation of current treatment recommendations.

SOLUTION: no

PROBLEM: Question: Does trinitrotoluene induce Endoplasmic Reticulum Stress and Apoptosis in HePG2 Cells?
Answer: TNT could increase the expression levels of GRP78, GRP94, Caspase-4, and CHOP in HePG2 cells; this increase in protein expression might be involved in HePG2 apoptosis through the induction of the ERS pathway.

SOLUTION:
yes
