Babies who suffer oxygen deficiencies during birth are at risk of brain damage that can lead to developmental delays, cerebral palsy and even death. To prevent this, most women in labor undergo continuous monitoring of the baby’s heart rate and receive supplemental oxygen if the heart rate is abnormal, with the thought that this common practice increases oxygen delivery to the baby. However, there is conflicting evidence about whether this long-recommended practice improves infant health.

As people age, a normal brain protein known as amyloid beta often starts to collect into harmful amyloid plaques in the brain. Such plaques can be the first step on the path to Alzheimer’s dementia. When they form around blood vessels in the brain, a condition known as cerebral amyloid angiopathy, the plaques also raise the risk of strokes.

People diagnosed with obstructive sleep apnea, or OSA, experience frequent disruptions of breathing while asleep. Those disruptions can range in frequency from five times in an hour for mild sleep apnea to 30 times or more for severe sleep apnea. In other words, a person with severe OSA stops and starts breathing at least every two minutes within an hour.

The very first X-ray image is a blurry, ghostlike view of a woman’s left hand, two sizable wedding rings visible on her third finger. Using his wife as his test subject, German physicist Wilhelm Röntgen used the power of the X-ray to gaze at bones beneath his wife’s skin, something he couldn’t have done before without an incision. Six years later, Röntgen won the 1901 Nobel Prize in Physics. The practice of medicine had changed forever.

All that holds true for the use of robotics in partial knee replacement surgery, also called unicompartmental knee arthroplasty or UKA. In fact, a team of Washington University orthopedic researchers found that using robotics during UKA yielded results that were up to 10 times more accurate than doing the procedure without robotic assistance. The study was published in The Bone & Joint Journal, March 2021.
