Chronic use of some drugs for heartburn and gastroesophageal reflux (GERD) speeds up the aging of blood vessels, according to a published paper in Circulation Research (early online), an American Heart Association journal. This accelerated aging in humans could lead to increased cardiovascular disease, vascular dementia and renal failure.
In Alzheimer’s disease, plaques of amyloid beta protein accumulate in the brain, damaging connections between neurons. Now, researchers at University of California San Diego School of Medicine and Harvard Medical School have found that the enzyme Protein Kinase C (PKC) alpha is necessary for amyloid beta to damage neuronal connections. They also identified genetic variations that enhance PKC alpha activity in patients with Alzheimer’s disease.
With more than 13 percent of Americans currently over age 65, and that proportion expected to grow in the coming decades, psychology has played and will continue to play an important part in helping seniors maintain their health, adjust to retirement and prevent cognitive decline, according to the flagship journal of the American Psychological Association.
Newly discovered genetic switches that increase lifespan and boost fitness in worms are also linked to increased lifespan in mammals, offering hope that drugs to flip these switches could improve human metabolic function and increase longevity.

Patients with age-related macular degeneration (AMD), the most common cause of major vision loss in older people, still show benefits from a new class of therapy -- originally developed to treat cancer -- after long-term treatment.
Frailty, a condition that affects 10 percent of people aged 65 and older, can make older adults more prone to disability, falls, hospitalization and a shorter lifespan. Recently, researchers writing in the Journal of the American Geriatrics Society examined the effects of frailty and depression on married couples. Although we know much about the effects of frailty and depression on individuals, up until now, little has been uncovered about how these two conditions may be connected within couples.
Researchers writing in the Journal of the American Geriatrics Society recently learned that older women who are frail, and who have six or more chronic health conditions, are twice as likely to have a lower quality of life compared to women with less than three risk factors.

• Systolic blood pressure levels above 140 mmHg were linked with higher risks of coronary heart disease, stroke, kidney failure, and death in patients with chronic kidney disease of all ages, but the magnitude of these associations diminished with more advanced age. • Diastolic blood pressure levels below 70 mmHg were associated with a higher risk of death, but otherwise they showed no association with cardiovascular outcomes
Long before Alzheimer’s disease can be diagnosed clinically, increasing difficulties building cognitive maps of new surroundings may herald the eventual clinical onset of the disorder, finds new research from Washington University in St. Louis.“These findings suggest that navigational tasks designed to assess a cognitive mapping strategy could represent a powerful new tool for detecting the very earliest Alzheimer’s disease-related changes in cognition,” said senior author Denise Head, associate professor of psychological and brain sciences in Arts & Sciences.
An eight-year-long accrual and analysis of the whole genome sequences of healthy elderly people, or “Wellderly,” has revealed a higher-than-normal presence of genetic variants offering protection from cognitive decline, researchers from the Scripps Translation Science Institute reported.
It has been disorienting to the scientific and medical community as to why different subtle changes in a protein-coding gene causes many different genetic disorders in different patients -- including premature aging, nerve problems, heart problems and muscle problems. no other gene works like this. According to a new study, co-authored by Binghamton University faculty Eric Hoffman, it has to do with cell “commitment.”
Among adults 60 years of age or more, walking is the most common form of leisure-time physical activity because it is self-paced, low impact and does not require equipment. Researchers at the University of Missouri have determined that older adults who also are pet owners benefit from the bonds they form with their canine companions.

Older adults who met twice-weekly strength training guidelines had lower odds of dying in a new analysis by researchers at Penn State College of Medicine, Penn State Health Milton S. Hershey Medical Center and Columbia University.
Whether a creature is a worm, a fly, a mouse, or a human, death inevitably awaits. And not only do these organisms share a common fate, but also, according to a new study, they may share some of the specific mechanisms of mortality. The researchers found that in all four species, there are 46 genes regulated by the same family of "FOXO" proteins known to be central in aging and longevity.
A compound enriched in citrus peels strengthens the body clock and protects against metabolic syndrome in mice, according to a study led by scientists at The University of Texas Health Science Center at Houston (UTHealth).
Tested in both mice and human cells and produced in the energy-producing mitochondria of cells, the proteins may lead to greater understanding of aging-related diseases from diabetes to Alzheimer's to cancer.
Researchers at the University of California, San Diego School of Medicine have developed a novel method for assessing mortality risk in elderly patients with cancer who also suffer from other serious diseases or conditions. The prognostic model, they say, is more precise and provides a more useful tool for determining the best treatments when more than one disease is involved.
Researchers at Basel University Hospital in Switzerland investigate the biochemical and physiological characteristics of orbicularis oculi, a group of facial muscles that control the eyelids and are selectively spared or involved in different neuromuscular disorders. What they found also helps to explain why another set of muscles—the extraocular muscles that control the movement of the eye—are not affected by Duchenne muscular dystrophy, congenital muscular dystrophy, and aging.
Kelly Mills, a finalist in the SSHRC Storyteller's challenge, tells the tale of her work with the Memory Writers, a remarkable group that has been writing and sharing stories with each other for more than 25 years.

A University of Guelph professor has uncovered the “secret” to staying strong as we age – superb fitness. Geoff Power found elderly people who were elite athletes in their youth or later in life – and who still compete as masters athletes — have much healthier muscles at the cellular level compared to those of non-athletes.
For most people, the culmination of a good life is a “good death,” though what that means exactly is a matter of considerable consternation. Researchers at the University of California, San Diego School of Medicine surveyed published, English-language, peer-reviewed reports of qualitative and quantitative studies defining a “good death,” ultimately identifying 11 core themes associated with dying well.
To understand how people can live longer throughout the world, researchers at University of California, San Diego School of Medicine have teamed up with colleagues at University of Rome La Sapienza to study a group of 300 citizens, all over 100 years old, living in a remote Italian village nestled between the ocean and mountains on the country’s coast.
Assistant professor Javier Apfeld plumbs the cellular mechanisms driving the aging process in worms, uncovering insights that could increase our own longevity.
Exercise in older people is associated with a slower rate of decline in thinking skills that occurs with aging. People who reported light to no exercise experienced a decline equal to 10 more years of aging as compared to people who reported moderate to intense exercise, according to a population-based observational study published in the March 23, 2016, online issue of Neurology®, the medical journal of the American Academy of Neurology.
Cell’s protein factory may hold key to stalling cognitive decline.
When it comes to aging, the focus is not just on living longer, quality of life is equally important. According to the National Institute on Aging, people aged 50 and older need more of some vitamins and minerals than younger adults do. In the March issue of Food Technology magazine published by the Institute of Food Technologists (IFT), Linda Mila Ohr wrote about 8 essential nutritional ingredients that can help aging individuals maintain an active lifestyle.
Imagine telling a patient suffering from age-related (type-II) osteoporosis that a single injection of stem cells could restore their normal bone structure. This week, with a publication in STEM CELLS Translational Medicine, a group of researchers from the University of Toronto and The Ottawa Hospital suggest that this scenario may not be too far away.
A new study published in Physiological Genomics suggests that the brain shows signs of aging earlier than old age. The study found that the microglia cells—the immune cells of the brain—in middle-aged mice already showed altered activity seen in microglia from older mice.
Could an unhealthy diet and lack of exercise be making you age faster? Researchers at Mayo Clinic believe there is a link between these modifiable lifestyle factors and the biological processes of aging. In a recent study, researchers demonstrated that a poor diet and lack of exercise accelerated the onset of cellular senescence and, in turn, age-related conditions in mice. Results appear today in Diabetes.
