A 7-year comprehensive study of deaths attributed to out of hospital cardiac arrest (OHCA) in San Francisco found that more than one in six of those deaths were actually from occult overdose. These findings suggest that published national overdose mortality estimates may be substantially underestimated. A brief research report is published in Annals of Internal Medicine.
New research by neuroscientists at the University of Pittsburgh and UC San Francisco (UCSF) revealed that a simple, earbud-like device developed at UCSF that imperceptibly stimulates the brain could significantly improve the wearer's ability to learn the sounds of a new language. This device may have wide-ranging applications for boosting other kinds of learning as well.
Research shows that severe hearing loss in childhood cancer survivors is associated with neurocognitive deficits independent of type of therapy.
The overall safety and benefits of using nasal saline irrigations on viral upper respiratory infections during a pandemic, such as COVID-19, are discussed in this Viewpoint.
Scientists have created an optical cochlear implant based on LED lights that can safely and partially restore the sensation of hearing in deaf rats and gerbils.
In a study of human ear tissues, scientists have demonstrated that age-related hearing loss is mainly caused by damage to hair cells. Their research challenges the prevailing view of the last 60 years that age-related hearing loss is mainly driven by damage to the stria vascularis, the cellular "battery" that powers the hair cell's mechanical-to-electrical signal conversion.
Age-related hearing loss has more to do with the death of hair cells than the cellular battery powering them wearing out, according to new research in JNeurosci. That means wearing ear protection may prevent some age-related hearing loss.
A preoperative procedure might enable surgeons to protect the language centers during brain tumor removal without needing to keep patients awake during surgery.

A study from Ann & Robert H. Lurie Children's Hospital of Chicago found that children with a MED-EL Synchrony cochlear implant device can undergo MRI safely, with no discomfort and reduced need for sedation or anesthesia. Findings were published in the peer-reviewed journal Laryngoscope.
