by Amsterdam University Medical Center Credit: Pixabay/CC0 Public DomainDutch scientists have discovered five biological variants of Alzheimer’s disease, which may require different treatments. As a result, previously tested drugs may incorrectly appear to be ineffective or only minimally effective. This is the conclusion of researcher Betty Tijms and colleagues from Alzheimer Center Amsterdam, Amsterdam UMC...

Renal macrophages observed playing crucial role in preventing kidney stones
by Justin Jackson , Medical Xpress Graphical abstract. Credit: Immunity (2023). DOI: 10.1016/j.immuni.2023.12.003Researchers at Zhejiang University School of Medicine, China, have investigated how the body’s innate immune system of renal macrophages works to prevent kidney stones. In a paper, “Renal macrophages monitor and remove particles from urine to prevent tubule obstruction,” published in Immunity, the...
New program for psoriasis patients highlights cardiovascular risk
by Perelman School of Medicine at the University of Pennsylvania Credit: Unsplash/CC0 Public DomainAlmost 30% of the patients in a pilot program for those with psoriasis that was devised by researchers from the Perelman School of Medicine at the University of Pennsylvania were identified as having undiagnosed, elevated risk for cardiovascular disease. Those patients were then...

Research discovers gene that links deafness to inner ear cell death
by Levi Gadye, University of California, San Francisco Graphical abstract. Credit: JCI Insight (2023). DOI: 10.1172/jci.insight.172665 Researchers have found a gene that links deafness to cell death in the inner ear in humans—creating new opportunities for averting hearing loss.A person’s hearing can be damaged by loud noise, aging and even certain medications, with little recourse beyond...
Out-of-pocket cost increase could put HIV prevention medications out of reach
by Perelman School of Medicine at the University of Pennsylvania Credit: Unsplash/CC0 Public DomainIncreasing patients’ out of pocket costs for HIV pre-exposure prophylaxis (PrEP), medications, which have been shown to dramatically reduce the risk of HIV infection, could lead to a significant reduction in PrEP use and a rise in HIV infection rates, according to a...
Update on mechanisms and management of atrial fibrillation
by Cactus Communications heart attackCredit: Pixabay/CC0 Public DomainAtrial fibrillation (AF) is a major global health concern impacting millions and causing symptoms like palpitations, dyspnea, fatigue, dizziness, and chest discomfort.
