Just a few hundred years ago, the heart and its function were a bit of a mystery.
On Oct. 1, Tsuyoshi Kaneko, MD, was named the Shoenberg Professor of Surgery and chief of cardiac surgery at Washington University School of Medicine in St. Louis and Barnes-Jewish Hospital.
Why should cardiologists refer patients to an advanced heart failure specialist?
E-cigs were praised as a healthier alternative to cigarettes when they were first invented, but a study looking at dual nicotine use says otherwise.
30% – 50% of older adults have mild sleep apnea: a condition that causes breathing to repeatedly stop and start during sleep. Some people may not have any signs or symptoms of impairment, resulting in increased risks when getting behind a steering wheel.
Noah was just six years old when he walked up behind someone mowing the lawn who didn’t know he was there. In an instant, as the lawnmower was backed up, Noah’s foot was caught underneath it, sharp blades cutting through skin, muscle and bone in his foot and toes. “They told us at the hospital that his foot might have to be amputated,” says Hingst. “We were in total shock.”
The beeping vibrato of pressure monitors, mechanical rhythm of the blood pump, low hum of the oxygenator and metronomic beat measuring heart rate: These are the sounds that emanate from a complex circuit of pumps, tubes, filters and monitors called ECMO, or extracorporeal membrane oxygenation. ECMO moves blood outside of the body through cannulae, or tubes, to an oxygenator that provides a gas exchange in the blood, removing carbon dioxide and replacing it with oxygen. The oxygenated blood is then warmed to the appropriate temperature and returned to the body using rhythms that mimic a beating heart.
When disease or trauma prevent the body from performing these life-sustaining rhythms, ECMO can take over.
Three billion is such a large number that it’s hard to fathom. To put it in perspective:
Three billion also happens to be the number of DNA building blocks, or base pairs, that make up a human genome. And nearly every single cell in our bodies contains two copies of those 3 billion base pairs.
Functional neurosurgery—surgical interaction with the brain to improve function—was pioneered to treat people in need of pain relief, often those suffering with terminal cancer. Simple early procedures included surgically creating tiny lesions, also called ablations, in specific areas of the nervous system linked to pain.
The field has come a long way since those early days, says Jon Willie, MD, PhD, Washington University neurosurgeon at Barnes-Jewish Hospital.
