Researchers are trying to counter the biological causes of hearing loss—rather than just treating the effects

By Brian Gormley Sept. 15, 2019 10:04 pm ET Scientists are pursuing the first medicines to treat hearing loss.

World-wide, 466 million people have disabling hearing loss, including 34 million children, according to the World Health Organization. Children with severe to total hearing loss have lower literacy than their fully hearing peers, and their education is greatly compromised, according to a 2017 paper in the medical journal Lancet.

The company hopes a one-time treatment will let children with this rare disorder hear without a cochlear implant. Clinical trials are expected to begin in 2021, says Dr. Simons, adding. “Our hope is we might be able to restore true physiologic hearing that is very close to normal.” A synthetic virus carrying a healthy copy of the otoferlin gene is injected into an ear structure known as the round window.The fluid the virus is delivered into comes into contact with sensory hair cells in the inner ear that are required for hearing.hair cellSensory hair cells, equipped with the normal otoferlin gene, can now perform their job of transmitting sound vibrations that they convert into electrical signals to the brain.“This has some real promise,” Dr. Lustig says.

For children, “If Decibel Therapeutics could pair up with a company that has a better way of delivering what they have into the inner ear, I think they could do very well,” Dr. Chang says. Birds, fish, reptiles and amphibians spontaneously regenerate hair cells, but not humans, says Robert Jackler, chairman of the department of otolaryngology-head and neck surgery at Stanford University School of Medicine.

Listen Up: Hearing Aids May Do More Than Just Treat Hearing LossHearing aids are a bigger deal than you thought. A new study links their use in older people with hearing loss to a lower risk of dementia, depression and fall-related injuries over three years, compared with those who didn't wear hearing aids. New products coming next year may help affordability. starkeycares TheSharkDaymond PartnerUpᵀʰᵉᴹᵒᵛᵉᵐᵉⁿᵗ™ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Guys, next time you make lists and rankings of the worlds richest people, include 'public capital' in there along with private capital like stock values. Public capital = their investment in the commons, ie. their total taxes paid. That should move the rankings around more fairly I hope so. It’s a balancing tool for me. My brain works and I can rationalize why Trump is so EFFED UP.

Why The High Number Of Employees Quitting Reveals A Strong Job MarketWhile recession fears may be looming in the minds of some, new data from the Bureau of Labor Statistics shows that the economy and job market may actually be strengthening. Only for the supposed 18% in the upper class. Our jobs are shit paying, but plentiful. Can it not be Job Dissatisfaction or no growth or limited opportunities? That's not such a big surprise. Low unemployment means it's easier to find a job.. I would love the BLS_gov to measure how many people start working in a role or a company that isn't a fit for them, and leaving or get fired while costing energy and money to both sides.
