退行性疾病的到来通常意味着老年黄金岁月遭受破坏，但妙佑医疗国际(Mayo Clinic)的一项研究发现，再生医学可以减缓退行性疾病的发展。自1950年代以来，人类的寿命几乎翻番，但无病痛的健康寿命却没有同步跟上。根据发表在《NPJ 再生醫學》（NPJ Regenerative Medicine）上的一篇论文，人的寿命普遍有所增长，但在最后的十年里，往往会饱受与年龄相关的慢性疾病的困扰，这些疾病降低了生活质量。人在最后几年的时光往往会给社会带来巨大的成本负担。
وجدت دراسة أجرتها مايو كلينك أن الطب التجديدي يمكن أن يبطئ عقارب الساعة بالنسبة للأمراض التنكسية التي غالبًا ما تدمر سنوات التقاعد. لقد تضاعف العمر الافتراضي تقريبًا منذ الخمسينيات من القرن الماضي، لكن الامتداد الصحّي - عدد السنوات الخالية من الأمراض - لم تواكب ذلك. وفقًا لورقة بحثية نُشرت في مجلة إن بي جيه للطب التجديدي، يعيش الناس عمومًا لفترة أطول، لكن العقد الأخير من العمر غالبًا ما يكون مليئًا بالأمراض المزمنة المرتبطة بالعمر والتي تقلل من جودة الحياة. وتأتي هذه السنوات الأخيرة مع كلفة كبيرة على المجتمع.

Using a stem-cell-derived model, researchers have identified two drug candidates that may slow dry age-related macular degeneration (AMD), a leading cause of blindness for which no treatment exists. The scientists, from the National Eye Institute (NEI), part of the National Institutes of Health, published their findings today in Nature Communications.

During pandemic-induced isolation, researchers from the University of Minnesota surveyed older adults with vision loss, with hearing loss, or without either condition, asking the participants about their worries, well-being, and social isolation at six-week intervals. All three groups scored lower on a patient health questionnaire after the pandemic began; however, people with vision or hearing loss faced unique problems in lockdown. Disruptions to mobility systems affected people with low vision, and masks made conversations especially difficult for adults with hearing loss.
Difficulty in understanding speech, especially in background noise, is a common concern for older adults. Using a word identification task in quiet and noisy conditions, researchers examined the impact of mild dementia on speech perception. They tested individuals with and without mild dementia and found that word identification scores of those without dementia were significantly better in all conditions, meaning people with mild dementia symptoms recalled fewer words in both quiet and noisy situations.

Researchers used telephone and web survey data to examine how health-related factors and social determinants such as income and social participation, impacted the prevalence of depressive symptoms during the initial lockdown starting March 2020 and after re-opening following the first wave of COVID-19 in Canada. Caregiving responsibilities, separation from family, family conflict, and loneliness were associated with a greater likelihood of moderate or high levels of depressive symptoms that got worse over time.

Studies suggest that exposure to the COVID-19 pandemic has been associated with a variety of different mental health consequences including reports of depression, loneliness, and insomnia. People who are more than 65 years of age and those with underlying medical conditions such as type 2 diabetes and obesity are particularly vulnerable to negative outcomes from COVID-19. Until now, few investigations have identified and separated the mental health consequences of exposure to the COVID-19 pandemic from preexisting factors in this age group. A new prospective study of a large cohort of older adults with type 2 diabetes and overweight/obesity from across the U.S. has explored this subject with surprising results.
ALEXANDRIA, Va. – A new study has found that the proportion of older Americans who need a liver transplant (LT) has sharply increased in recent years, often due to the rising number of cases of nonalcoholic steatohepatitis (NASH). As the U.S. population ages, researchers estimate that more patients aged 65 or older will need an LT than ever before.
Johns Hopkins has received a $20 million grant from the National Institute on Aging that will spur the development of artificial intelligence devices (AI) to improve the health of older adults and help them live independently for longer — a relatively untapped use of this technology.

A new study found that people with higher cumulative estrogen exposure over their lifetime had greater brain volumes and fewer indicators of brain disease on their brain scans in midlife . The research is published in the November 3, 2021, online issue of Neurology®, the medical journal of the American Academy of Neurology.
A new study suggests that healthy older people who eat two or more servings of fish a week, including salmon, tuna and sardines, may have a lower risk later in life of developing vascular brain disease, a group of conditions that affect blood flow and blood vessels in the brain. The research is published in the November 3, 2021, online issue of Neurology®, the medical journal of the American Academy of Neurology. The study found that eating a diet rich in fish had the greatest protective effect on people younger than 75 years old.
With two viruses threatening to make older adults sick this winter, a new poll shows most people over 50 have gotten protected by vaccines against both influenza and coronavirus, or plan to. And a majority of those who have gotten the COVID-19 vaccine plan to get an additional dose. But the poll also reveals major differences in vaccine attitudes between older adults, including those of different political leanings.
