Ozempic Hailed as 'Fountain of Youth' that Slows Aging

The anti-obesity drug Ozempic could slow down ageing and has “far-reaching benefits” beyond what was imagined, researchers have suggested.

Multiple studies have found semaglutide (available under the brand names Wegovy and Ozempic) reduced the risk of death in people who were obese or overweight and had cardiovascular disease without diabetes, The Independent reported.

Responding to research published in JACC, the flagship journal of the American College of Cardiology, Professor Harlan M Krumholz from the Yale School of Medicine, said: “Semaglutide, perhaps by improving cardiometabolic health, has far-reaching benefits beyond what we initially imagined.”

He added: “These ground-breaking medications are poised to revolutionise cardiovascular care and could dramatically enhance cardiovascular health.”

Multiple reports also quoted Professor Krumholz saying: “Is it a fountain of youth?”

He said: “I would say if you’re improving someone’s cardiometabolic health substantially, then you are putting them in a position to live longer and better.

“It’s not just avoiding heart attacks. These are health promoters. It wouldn’t surprise me that improving people’s health this way actually slows down the ageing process.”

The studies, presented at the European Society of Cardiology Conference 2024 in London, were produced from the Select trial which studied 17,604 people aged 45 or older who were overweight or obese and had established cardiovascular disease but not diabetes.

They received 2.4 mg of semaglutide or a placebo and were tracked for more than three years.

A total of 833 participants died during the study with 5 percent of the deaths were related to cardiovascular causes and 42 per cent from others.

Infection was the most common cause death beyond cardiovascular, but it occurred at a lower rate in the semaglutide group than the placebo group.

People using the weight-loss drug were just as likely to catch Covid-19, but they were less likely to die from it – 2.6 percent dying among those on semaglutide versus 3.1 per cent on the placebo.

Researchers found women experienced fewer major adverse cardiovascular events, but semaglutide “consistently reduced the risk” of adverse cardiovascular outcomes regardless of sex.

Dr Benjamin Scirica, lead author of one of the studies and a professor of cardiovascular medicine at Harvard Medical School, said: “The robust reduction in non-cardiovascular death, and particularly infections deaths, was surprising and perhaps only detectable because of the Covid-19-related surge in non-cardiovascular deaths.

“These findings reinforce that overweight and obesity increases the risk of death due to many etiologies, which can be modified with potent incretin-based therapies like semaglutide.”

Dr Jeremy Samuel Faust, an emergency medicine physician at Brigham and Women’s Hospital, praised the researchers for adapting the study to look at Covid-19 when the pandemic started.

He said the findings that the weight-loss drug to reduce Covid-19 mortality rates were “akin to a vaccine against the indirect effects of a pathogen.”

Australian Sauna Helps Save Frogs from Flesh-Eating Fungus

Hundreds of endangered Australian Green and Golden Bell frogs huddle inside a sauna, shielded from Sydney's winter chill.

The sauna -- a small greenhouse containing black-painted bricks warmed by the sun -- may be pleasant, but it also protects the frogs from a deadly chytrid fungus that would otherwise drive them to extinction.

Macquarie University biologist Anthony Waddle holds one frog -- no bigger than a credit card -- in his hand as its green and gold colors become more vibrant in the heat.

"Chytrid is the worst pathogen ever", he told AFP.

It is a water-borne disease that burrows into the frogs' skin, attacking their bodies and eventually killing them.

Waddle said that globally, the disease has caused the decline of 500 amphibian species and driven 90 to extinction -- six in Australia.

"Nothing has ever caused this much devastation," he told AFP. "In Australia, we have frogs that only live in glass boxes now. This is a huge, ongoing problem."

But Waddle's dollhouse-sized saunas could change that.

In their warm interiors, the deadly chytrid fungus cannot grow on the frogs, allowing them to fight off the infection and survive.

-'No one solution' -

Frogs play a vital role in the environment and are known as bioindicators, which are used to assess the health of ecosystems.

Without the amphibians, entire ecosystems can collapse.

Globally, 41 percent of frog species are threatened with extinction, making them one of the most vulnerable invertebrate groups, a recent study by the International Union for Conservation of Nature found.

Some of the biggest drivers include loss of habitat, climate change and the chytrid disease.

These drivers are difficult to tackle, but in the absence of a cure, Waddle hopes his frog saunas can help limit the losses.

"This might be the first evidence that we could cheaply and feasibly reduce that nasty yearly die-off of frogs," Waddle said.

"For Green and Golden Bell frogs, that could mean the difference between a population going or persisting."

He said the saunas show that creative solutions ranging from the complex -- such as identifying genes that could make individuals resistant to chytrid -- to more simple are needed if frog populations are to survive.

"Not one solution is going to work for everything. Frogs are so different," Waddle added.

But the beauty of Waddle's saunas is that they cost AUD$70 ($US50) to assemble, and he has helped dozens of citizen scientists build their own backyard versions.

This has not only provided valuable data about endangered frog species but also saved some from the deadly fungus.

Jodi Rowley, an amphibian biologist from the Australian Museum, said the saunas showed how creative solutions could have real-world benefits.

"It's easy to feel helpless in the face of biodiversity declines, but this study gives us a tangible way we may be able to help frogs battling a devastating fungal disease," she told AFP.
