Using an AI tool, researchers at Karolinska Institutet have analyzed brain images from 70-year-olds and estimated their brains' biological age. They found that factors detrimental to vascular health, such as inflammation and high glucose levels, are associated with an older-looking brain, while healthy lifestyles were linked to brains with a younger appearance. The results are…

A new publication from Genes & Diseases; DOI 10.1016/j.gendis.2024.101284, discusses the effect of long-term administration of green tea catechins on aging-related cardiac diastolic dysfunction and decline of troponin I. Aging is an independent risk factor for cardiovascular diseases. Cardiac diastolic dysfunction (CDD), ultimately leading to heart failure with preserved ejection fraction (HFpEF), is prevalent among older…

UC Davis Director of Pediatric Electrophysiology Dan Cortez has set another world record: He is the first to implant a dual chamber leadless pacemaker in a child. His case report was published this week in the journal PACE: Pacing and Clinical Electrophysiology. A 13-year-old patient was referred to the UC Davis pediatric electrophysiology clinic for presyncope, a…

Evaluating how individuals perceive their walking pace compared to peers may emerge as a key public health tool A study published in Scientific Reports describes the association between walking speed and the risk of metabolic diseases in individuals with obesity. Background Walking speed, together with heart rate and blood pressure, is considered to…

Keith Poulsen's jaw dropped when farmers showed him images on their cellphones at the World Dairy Expo in Wisconsin in October. A livestock veterinarian at the University of Wisconsin, Poulsen had seen sick cows before, with their noses dripping and udders slack. But the scale of the farmers' efforts to treat the sick cows stunned…

People who suffer from continued symptoms of concussion should seek a referral to physical therapy as soon as possible, new research from Oregon Health & Science University suggests. Even though most people naturally recover from concussions within four weeks, the study revealed people who delayed physical therapy had lingering deficits related to their reaction times for…

Tom Contos is an avid runner. When he started experiencing rectal bleeding in March, he thought exercise could be the cause and tried to ignore it. But he became increasingly worried when the bleeding continued for weeks. The Chicago health care consultant contacted his physician at Northwestern Medicine, who referred him for a diagnostic colonoscopy,…

A new study shows that an app can help parents who are mourning the loss of a child. Parents who used the app for three months reported reduced symptoms of prolonged grief and post-traumatic stress, and also had fewer negative thoughts. Some parents thought the app should be offered early in the mourning process. This…

Researchers from the University of Missouri are studying potential therapies to target specific cells linked to the development of cardiovascular and metabolic disorders like high blood pressure and type 2 diabetes.  A newly released study focused on a cluster of chemoreceptors cells located near the carotid artery in the neck. When overactive, the cells are…
