Novo Nordisk's Wegovy obesity drug reduced adverse kidney-related events by 22% in overweight and obese people in a large study, according to a new analysis the Danish drugmaker published on Saturday.

The analysis, from a large study for which substantial results had been released by Novo last year, was presented at the European Renal Congress in Stockholm.

"By addressing key markers of kidney health, semaglutide...may contribute to a significant reduction in the risk of kidney-related complications, including chronic kidney disease and end-stage renal disease," said Professor Helen M. Colhoun of the University of Edinburgh and lead study author.

A Novo spokesperson said in a statement to Reuters that the new analysis "demonstrates for the first time the benefits of semaglutide 2.4 mg in improving kidney function in people with cardiovascular disease and overweight or obesity, without diabetes, a high-risk population with increased need for kidney protection."

The study follows the publication in March of a Novo study showing its diabetes drug Ozempic delayed progression of chronic kidney disease in diabetes patients. Ozempic contains the same active ingredient, semaglutide, as Wegovy, which is approved as an obesity treatment.

The latest data adds to growing body of medical evidence that drugs from the GLP-1 class, which suppress appetite by mimicking gut hormones, have medical benefits for conditions beyond type 2 diabetes and weight loss, their initial purposes.

In the new analysis, semaglutide led to a slower decline in a certain measure of kidney function known as eGFR (estimated glomerular filtration rate), particularly in individuals with a pre-existing kidney impairment.

There was also a significant reduction in the urinary albumin-to-creatine ratio (UACR), another important marker of kidney health, the analysis found.

Regardless of kidney function at the start of the study, "no increased risk of acute kidney injury was associated with semaglutide", it found.

The analysis examined data from a large trial by Novo Nordisk called Select. Initial results from that were published in August.

The 17,604-patient trial tested Wegovy not for weight loss or kidney function but for its heart protective benefits for overweight and obese patients who had preexisting heart disease but not diabetes.

The analysis published on Saturday comes a day after Novo presented detailed results of a separate late-stage trial showing its diabetes drug Ozempic slowed the worsening of kidney dysfunction in patients with type 2 diabetes and lowered the risk of kidney failure, heart problems, stroke and death.



Killer Whales Spotted Grooming Each Other with Seaweed

Killer whales have been caught on video breaking off pieces of seaweed to rub and groom each other, scientists announced Monday, in what they said is the first evidence of marine mammals making their own tools.

Humans are far from being the only member of the animal kingdom that has mastered using tools. Chimpanzees fashion sticks to fish for termites, crows create hooked twigs to catch grubs and elephants swat flies with branches.

Tool-use in the world's difficult-to-study oceans is rarer, however sea otters are known to smash open shellfish with rocks, while octopuses can make mobile homes out of coconut shells.

A study published in the journal Current Biology describes a new example of tool use by a critically endangered population of orcas., AFP reported.

Scientists have been monitoring the southern resident killer whales in the Salish Sea, between Canada's British Columbia and the US state of Washington, for more than 50 years.

Rachel John, a Masters student at Exeter University in the UK, told a press conference that she first noticed "something kind of weird" going on while watching drone camera footage last year.

The researchers went back over old footage and were surprised to find this behavior is quite common, documenting 30 examples over eight days.

One whale would use its teeth to break off a piece of bull kelp, which is strong but flexible like a garden hose.

It would then put the kelp between its body and the body of another whale, and they would rub it between them for several minutes.

The pair forms an "S" shape to keep the seaweed positioned between their bodies as they roll around.

Whales are already known to frolic through seaweed in a practice called "kelping".

They are thought to do this partly for fun, partly to use the seaweed to scrub their bodies to remove dead skin.

The international team of researchers called the new behavior "allokelping," which means kelping with another whale.

They found that killer whales with more dead skin were more likely to engage in the activity, cautioning that it was a small sample size.

Whales also tended to pair up with family members or others of a similar age, suggesting the activity has a social element.

The scientists said it was the first known example of a marine mammal manufacturing a tool.

Janet Mann, a biologist at Georgetown University not involved in the study, praised the research but said it "went a bit too far" in some of its claims.

Bottlenose dolphins that use marine sponges to trawl for prey could also be considered to be manufacturing tools, she told AFP.

And it could be argued that other whales known to use nets of bubbles or plumes of mud to hunt represent tool-use benefitting multiple individuals, another first claimed in the paper, Mann said.

Michael Weiss, research director at the Center for Whale Research and the study's lead author, said it appeared to be just the latest example of socially learned behavior among animals that could be considered "culture".

But the number of southern resident killer whales has dwindled to just 73, meaning we could soon lose this unique cultural tradition, he warned.

"If they disappear, we're never getting any of that back," he said.

The whales mainly eat Chinook salmon, whose numbers have plummeted due to overfishing, climate change, habitat destruction and other forms of human interference.

The orcas and salmon are not alone -- undersea kelp forests have also been devastated as ocean temperatures rise.

Unless something changes, the outlook for southern resident killer whales is "very bleak," Weiss warned.
