Study in Mice Suggests How Anesthesia May Fight Lung Infections

In experiments in mice, researchers at Johns Hopkins and elsewhere have added to evidence that certain so-called “volatile” anesthetics — commonly used during surgeries — may also possess powerful effects on the immune system that can combat viral and bacterial infections in the lung, including influenza and pneumonia.

Genetic Landscape Can Impact Treatment for Children with Rare, Aggressive Cancer

For children with rare, aggressive and advanced cancer, precision medicine may help doctors determine their best treatment options, a new study finds. Using information from a patient’s entire genome helped suggest personalized treatment options for nearly half of children with cancer, and led to specific treatment changes in a quarter of these patients.

Diabetic Retinopathy Screening for Children with Type 1 Diabetes Should Start at Later Stage, New Study Says

Boywitheyedoctor.jpg

A new study has found that the occurrence of advanced forms of a diabetic eye disease remains low among children living with diabetes, regardless of how long they have had the disease or their ability to keep blood sugar levels controlled. Researchers are therefore recommending that most children with type 1 diabetes delay annual diabetic retinopathy screenings until age 15, or 5 years after their diabetes diagnosis, whichever occurs later. Their findings were published online today in Ophthalmology, the journal of the American Academy of Ophthalmology

Circuit in the Eye Relies on Built-in Delay to See Small Moving Objects

When we move our head, the whole visual world moves across our eyes. Yet we can still make out a bee buzzing by or a hawk flying overhead, thanks to unique cells in the eye called object motion sensors. A new study on mice helps explain how these cells do their job, and may bring scientists closer to understanding how complex circuits are formed throughout the nervous system. The study was funded by the National Institutes of Health, and was published online in Nature.
