Older adults with type 1 diabetes typically have low blood sugar, or hypoglycemia, for more than an hour a day, suggests research to be presented Monday, March 25, at ENDO 2019, the annual meeting of the Endocrine Society, in New Orleans, La.
Patients in a new Northwestern Medicine study were able to comprehend words that were written but not said aloud. They could write the names of things they saw but not verbalize them. For instance, if a patient in the study saw the word 'hippopotamus' written on a piece of paper, they could identify a hippopotamus in flashcards. But when that patient heard someone say 'hippopotamus,' they could not point to the picture of the animal.
Oxford University researchers have discovered a brain process common to sleep and aging in research that could pave the way for new treatments for insomnia.
Researchers from the George Washington University and the Moscow Institute of Physics and Technology have developed a solution for multiparametric optical mapping of the heart's electrical activity. This technique is a useful tool for enhancing our understanding of the mechanisms behind cardiac arrhythmias. Arrhythmia causes your heart to beat too quickly, too slowly or erratically. Hijacking the heart's vital rhythm and pumping function can have serious consequences like a stroke or cardiac arrest.
A UCLA-led study confirms what women approaching menopause have long suspected: menopause does make fat go up. The study finds that women undergoing perimenopause lost lean body mass and more than doubled their fat mass. The research demonstrates that body mass index (BMI) is a very important clinical tool for predicting health events, such as getting diabetes or having cardiovascular disease -- but is a less useful gauge of cardio-metabolic risk in older women.
Seemingly harmless fluid-filled spaces around the cerebral small vessels, commonly seen on brain MRIs in older adults, are now thought to be associated with more compromised cognitive skills, according to a Vanderbilt University Medical Center study published in Neurology.
Seychelles warblers live and breed in family groups on the tiny island of Cousin. In each group, a dominant female and male reproduce. When helpers assist the with incubation and feeding of chicks, the dominant female breeders age more slowly and live longer, a study by biologists from the University of Groningen and colleagues shows. The results indicate how cooperative breeding -- which also occurs in other species, including humans -- can increase life span.
Research shows that females age more slowly and live longer when they have help raising their offspring. Researchers studied the relationship between ageing and offspring rearing patterns in the Seychelles warbler, and found that females who had assistance from other female helpers benefitted from a longer, healthier lifespan. The findings help explain why social species, such as humans, which live in groups and cooperate to raise offspring, often have longer lifespans.
This study looked at the association of calcium intake (dietary and supplementation) with the risk and progression of age-related macular degeneration (AMD), a leading cause of blindness. Previous research has had mixed results about the role of calcium in AMD progression. This study, a secondary analysis of 4,751 randomized clinical trial participants, found higher calcium intake was associated with lower risk of progression to late AMD but there was an inconsistent association between calcium intake and different stages of AMD.
Researchers at Joslin Diabetes Center have uncovered a new mechanism of lifespan extension that links caloric restriction with immune system regulation.
