When does life end? New organ donation strategy fuels debate
On a chilly holiday Monday in January 2020, a medical milestone passed largely unnoticed. In a New York City operating room, surgeons gently removed the heart from a 43-year-old man who had died and shuttled it steps away to a patient in desperate need of a new one.
More than 3500 people in the United States receive a new heart each year. But this case was different—the first of its kind in the country. “It took us 6 months to prepare,” says Nader Moazami, surgical head of heart transplantation at New York University (NYU) Langone Health, where the operation took place. The run-up included oversight from an ethi...

Scientists tie third clinical trial death to experimental Alzheimer ’s drug
As enthusiasm mounts for a new experimental antibody that appears to slow cognitive decline in some Alzheimer’s patients, a third death linked to the drug during its clinical testing may amplify concerns about its safety.

The final puff: Can New Zealand quit smoking for good?
Smoking kills. Ayesha Verrall has seen it up close. As a young resident physician in New Zealand’s public hospitals in the 2000s, Verrall watched smokers come into the emergency ward every night, struggling to breathe with their damaged lungs. Later, as an infectious disease specialist, she saw how smoking exacerbated illness in individuals diagnosed with tuberculosis and HIV/AIDS. She would tell them: “The best thing you can do to promote your health, other than take the pills, is to quit smoking.”
Verrall is still urging citizens to give up cigarettes—no longer just one by one, but by the thousands. As New...

City Heat is Worse if You ’re Not Rich or White. The World’s First Heat Officer Wants to Change That
Jane Gilbert knows she doesn’t get the worst of the sticky heat and humidity that stifles Miami each summer. She lives in Morningside, a coastal suburb of historically preserved art deco and Mediterranean-style single-family homes. Abundant trees shade the streets and a bay breeze cools residents when they leave their air conditioned cars and homes. “I live in a place of privilege and it’s a beautiful area,” says Gilbert, 58, over Zoom in early June, shortly after beginning her job as the world’s first chief heat officer, in Miami Dade county. “But you don’t have to go far to see t...

No such thing as 'fat but fit', major study finds
‘Metabolically healthy obese’ are 50% more likely to suffer heart disease than those of normal weight, finds University of Birmingham studyPeople who are obese run an increased risk of heart failure and stroke even if they appear healthy, without the obvious warning signs such as high blood pressure or diabetes, according to a major new study.The findings, presented at the European Congress on Obesity in Porto, Portugal, may be the final death knell for the claim that it is possible to be obese but still metabolically healthy – or “fat but fit” – say scientists.Continue reading...

Declines In Dementia: Of Hearts And Minds
In this season when we are meant to be thankful, but when so many of us have had so many reasons to be otherwise, we have received a timely, welcome bit of universally good news. Rates of dementia in the United States appear to be declining.
This news reaches us courtesy of a study published recently in JAMA Internal Medicine. The investigators used standard, validated measures of cognitive function and dementia in two groups of more than 10,000 people in the U.S. with an average age of roughly 75 in the year 2000, and again in 2012. The overall rate of dementia declined over that span from 11.6% to 8.8%.

Men From The South Are More Likely To Die From Smoking-Related Cancers
Smoking causes nearly 29 percent of all cancer deaths among Americans over the age of 35, according to a new analysis published in JAMA Internal Medicine. But that doesn’t tell the full story.
Men from the top five southern states skew this data, dying at a rate that’s 40 percent higher than the national average.
The higher proportion of cancer deaths attributable to smoking in the South isn’t simply because people in that region smoke more ― that distinction goes to the Midwest. Instead, experts say, the lack of funding for tobacco control programs means that there are less resources for people wh...

The Bonus Effect: One Kind of Interest That Rewards DON'T Kill
For nearly half a century, research has raised troubling questions about the practice of dangling rewards in front of people to get them to do what we want. It doesn't matter whether the people in question are male or female, children or adults. It doesn't matter whether the rewards are stickers, food, grades, or money. It doesn't matter whether the goal is to get them to work harder, learn better, act nicely, or lose weight. What the studies keep telling us is that rewards, like punishments, tend not only to be ineffective -- particularly over the long haul -- but often to undermine the very thing we're trying to promote....

A Review of Risk Factors for Cognitive Impairment in Stroke Survivors.
Authors: Mohd Zulkifly MF, Ghazali SE, Che Din N, Singh DK, Subramaniam P
Abstract
In this review, we aimed to identify the risk factors that may influence cognitive impairment among stroke survivors, namely, demographic, clinical, psychological, and physical determinants. A search from Medline, Scopus, and ISI Web of Science databases was conducted for papers published from year 2004 to 2015 related to risk factors of cognitive impairment among adult stroke survivors. A total of 1931 articles were retrieved, but only 27 articles met the criteria and were reviewed. In more than half of the articles it was found tha...

If you can't imagine things, how can you learn?
We know some people can’t conjure up mental images. But we’re only beginning to understand the impact this “aphantasia” might have on their educationNever underestimate the power of visualisation. It may sound like a self-help mantra, but a growing body of evidence shows that mental imagery can accelerate learning and improve performance of all sorts of skills. For athletes and musicians, “going through the motions,” or mentally rehearsing the movements in the mind, is just as effective as physical training, and motor imagery can also help stroke patients regain function of their paralysed limbs.For most of us,...
