- No bones about it, this protein slows down fracture-healing September 19, 2019Broken bones are a bigger deal the older you are: healed bones of older people are weaker and more likely to re-fracture. Scientists found that a certain protein, which is more prevalent in older people, interferes with bone healing. They hope this discovery will lead to new treatments to help people heal after injuries or […]
- AAN recommends people 65+ be screened yearly for memory problems September 19, 2019To help physicians provide the highest quality patient-centered neurologic care, the American Academy of Neurology (AAN) is recommending physicians measure how frequently they complete annual assessments of people age 65 and older for thinking and memory problems.
- Suntanner, heal thyself: Exosome therapy may enable better repair of sun, age-damaged skin September 19, 2019In a proof-of-concept study, researchers have shown that exosomes harvested from human skin cells are more effective at repairing sun-damaged skin cells in mice than popular retinol or stem cell-based treatments currently in use. Additionally, the nanometer-sized exosomes can be delivered to the target cells via needle-free injections.
- Pathways linking childhood stressors and socioeconomic status to longevity September 18, 2019New research has found that individuals raised in families with higher socioeconomic status were more optimistic in midlife, and in turn, lived longer. Those who experienced more psychosocial stressors, such as parental death, frequent moves and harsh discipline, tended to encounter more stressful life events in midlife, and had greater risk of dying.
- Kidney disease: Senescent cell burden is reduced in humans by senolytic drugs September 18, 2019In a small safety and feasibility clinical trial, researchers have demonstrated for the first time that senescent cells can be removed from the body using drugs termed 'senolytics.' The result was verified not only in analysis of blood but also in changes in skin and fat tissue senescent cell abundance.
- Exercise could slow withering effects of Alzheimer's September 17, 2019Exercising several times a week may delay brain deterioration in people at high risk for Alzheimer's disease, according to a new study that scientists say merits further research to establish whether fitness can affect the progression of dementia.
- Alzheimer's disease risk gene APOE4 impairs function of brain immune cells September 16, 2019A study carried out with a new human stem cell-derived model reveals that the most prevalent genetic risk factor of Alzheimer's disease (AD), apolipoprotein E4 (APOE4), impairs the function of human brain immune cells, microglia. These findings pave the way for new, effective treatment approaches for AD.
- Addressing serious illness with a serious question to clinicians September 13, 2019A question: 'Would you be surprised if this patient died in the next month?' -- posed to elicit a clinician's overall impression of a patient -- produced a strong correlation. If a clinician answered that they would not be surprised, the patient was twice as likely to die in the next month.
- Repeated periods of poverty accelerate the aging process September 12, 2019People who have found themselves below the relative poverty threshold four or more times in their adult life age significantly earlier than others.
- Advanced MRI brain scan may help predict stroke-related dementia September 12, 2019An advanced MRI brain scan analysis in patients with stroke-damaged blood vessels helped predict problems with thinking (planning, organizing information and processing speed) and dementia.
