Researchers have been able to document and visualize hearing loss-associated genes in the human inner ear, in a unique collaboration study between otosurgeons and geneticists. The findings illustrate that discrete subcellular structures in the human organ of hearing, the cochlea, are involved in the variation of risk of age-related hearing loss in the population.

Researchers have found that blocking the action of a protein called interleukin 6 (IL-6), part of the immune system, could resolve the delirium that often accompanies urinary tract infection (UTI) in elderly patients. Their study could pave the way for clinical trials of IL-6 inhibitors as a treatment for UTI-associated delirium in humans.

Having an elevated resting heart rate in old age may be an independent risk factor of dementia, according to a new study. Since resting heart rate is easy to measure and can be lowered through exercise or medical treatment, the researchers believe that it may help to identify people with higher dementia risk for early intervention.
