Do repeated stressors in adulthood increase the rate of biological ageing?
The current data demonstrate that repeated exposure to experimental stressors affects the rate of biological ageing in adult Eurasian blackbirds. Both telomeres and oxidative damage were affected by repeated stress exposure and thus can serve as blood-derived biomarkers of biological ageing.
Immediate postprocedural chest radiographs are not routinely needed after image-guided insertion of internal jugular central venous catheters and unnecessarily add to the cost of patient care.
