Researchers at Drexel University's College of Medicine, in a study published in the Journal of Voice in 2026, found that patients with a diagnosed voice disorder and no hearing loss had a 58% greater risk of cognitive impairment or dementia than matched controls. [^1]

After 12 months, 68.3% of lipedema patients who underwent liposuction achieved clinically relevant pain reduction of at least two points on a 10-point scale, compared with 7.6% of patients receiving conservative therapy. [^2]

The pig kidney functioned for a record 271 days before being removed in October 2025 to make way for a human transplant. [^3]

Timothy Endruzs, a 66-year-old American man, received a genetically modified pig kidney on January 25, 2025, to treat terminal kidney failure caused by type 2 diabetes. [^4]

The Drexel research team reported that hearing loss alone was associated with a 27% increased risk of cognitive decline compared with matched controls. [^5]

The Drexel study analyzed data on 833,417 patients during primary care well visits, beginning at least one year after a voice or hearing loss disorder diagnosis, comparing them to a control group without such disorders. [^6]

Researchers at Massachusetts General Hospital stated that the pig kidney worked as a bridge until a human transplant became available. [^7]

The patient spent 82 days on dialysis after the pig kidney was removed before receiving a human kidney transplant in January 2026. [^8]
