As Ozzy Osbourne announces stem cell therapy, experts urge caution, highlight risks
As rock legend Ozzy Osbourne has turned to stem cell therapy, some experts caution that it’s not for everyone.
At the start of his latest episode of “Ozzy Speaks” on SiriusXM with Billy Morrison, Osbourne revealed that he recently returned from a follow-up appointment “after having some stem cells put in me.”
The rocker also had a previous treatment approximately three months ago, as he stated in the episode.

“The thing is, you have it, and you go, ‘I don’t feel that great,’ but I don’t know what it would be like if I didn’t have it,” Osbourne said.
In the past several years, the musician has struggled with several serious medical problems that have impacted his mobility, including Parkinson’s disease, per a report.

After he first started stem cell treatment in 2020, he wanted “to be a part of the world again,” his daughter Kelly Osbourne said in a report at the time.

“Seeing, after one treatment of stem cell, what has happened and the progress that he’s made is mind-blowing,” she added.
Fox News Digital reached out Ozzy Osbourne for comment.
Below is an overview of the treatment — and what to know about the risks and benefits.
What are stem cells?
Stem cells are found in almost every tissue in the body, according to the Mayo Clinic website.
Some stem cells repair tissues after injury, while others have the potential to become different types of cells, such as brain cells, muscle cells in the heart or bone cells.
“We routinely use cellular therapies, including stem cells, to treat cancers of the blood and bone marrow,” Dr. Mikkael Sekeres, chief of the division of hematology of Sylvester Cancer Center at the University of Miami, told Fox News Digital.

“The theory is, we can give high doses of chemotherapy to people who have these cancers to eliminate the cancer, but those therapies may have such a high dose that we could wipe out the healthy cells in the bone marrow,” he said.
Alternatively, the doctor went on, experts can “rescue” the bone marrow by giving stem cells to a patient from a healthy donor.

Another advantage is that the healthy donor stem cells will produce a new immune system to attack and eliminate any remaining cancer, Sekeres added.
“Use of stem cells in this way has saved tens of thousands of lives,” he noted.
Therapies ‘largely experimental’
Stem cell therapies are only approved by the U.S. Food and Drug Administration (FDA) to treat certain cancers of the blood and immune system, according to the Centers for Disease Control and Prevention (CDC).
In 2023, the FDA also approved a cord blood-based cell therapy to decrease the risk of infection after stem cell transplants.

“Stem cell therapy given for other reasons is largely experimental and unproven,” Sekeres noted.
Despite its potential benefits, stem cell therapy isn’t considered a “silver bullet” for Parkinson’s disease treatment, according to Dr. Michael S. Okun, a Florida-based medical advisor to the Parkinson’s Foundation.

“Though there have been many advances in stem cell technology, the realization that Parkinson’s is a disease of more than just dopamine underscores the importance of multidisciplinary treatment,” Okun, who is also the executive director of the Norman Fixel Institute for Neurological Diseases University of Florida Health in Gainesville, Florida, told Fox News Digital.
All stem cell products require the FDA’s approval, according to the agency’s website.
“Folks interested in Parkinson’s stem cell therapy should be cautious if ever offered a treatment,” Okun said.

“We recommend requesting a copy of the institutional review board approval, which is a document verifying that investigators have been authorized to perform research in a human population.”
(An institutional review board ensures ethical treatment of research subjects.)
“Since stem cell therapy is still investigational, you should never be charged to participate in a research trial,” Okun noted.
“Folks interested in Parkinson’s stem cell therapy should be cautious if ever offered a treatment.”
“There is a large market for ‘stem cell tourism,’ in which people may be charged large sums of money, and in some cases irreversible side effects may follow a transplant.”
Potential adverse side effects
One type of stem cell therapy is a stem cell transplant, which involves infusing another person’s stem cells into the recipient’s body.
Sometimes these stem cells come from the bone marrow, which is known as a bone marrow transplant, according to experts.
In other cases, they are harvested from a baby’s umbilical cord, which is known as a cord blood transplant.

Some people may experience symptoms of rejection if their immune system recognizes the donor stem cells as “foreign” and starts to attack them.
Acute symptoms may include an itchy rash, diarrhea, general malaise, shortness of breath and yellowing of the eyes, according to the National Health Service.

Longer-term complications may include infertility, various cancers, cataracts, bone or muscle weakness, and damage to certain organs, such as the liver, kidney, lung or heart, per the National Cancer Institute’s website.
Stem cell therapy should not be viewed as a “fountain of youth,” Sekeres cautioned.
Previous research published in JAMA Network Open discovered a multi-bacterial outbreak among patients who received unapproved products that were marketed as stem cell therapies, he pointed out.
To verify that a therapy is FDA-approved, the agency recommends emailing ocod@fda.hhs.gov for information, according to its website.

Fitness influencer says one simple habit can help anyone get back in shape
NEWYou can now listen to Fox News articles!
Fitness influencer and trainer Mark Langowski, known on social media as @bodybymark, hosted a pushup and plank competition in New York City this week, where he urged the public to get up and get moving.
On his platform of nearly two million Instagram followers, Langowski asks fit people to share their workout routines. He was able to meet more in-shape New Yorkers at his Washington Square Park meet-up, in partnership with Oikos yogurt on May 12.
A male and a female winner who achieved the most pushups or held a plank the longest were gifted $500 each.

Besides the cash prize, the inspiration was to get more people moving, Langowski shared during an interview with Fox News Digital.

“[It’s] a way to encourage strength and overall fitness in New York City and all around the country,” he said.
“We got together and we’re doing a plank competition, pushup competition. We had a guy just do 111 pushups. We’re just getting people moving.”
FITNESS EXPERT REVEALS SIMPLE RULE TO GET IN SHAPE WITHOUT DREADING THE GYM: ‘JUST MOVE’
Langowski said the attributes of a great competitor include strength, humility and confidence.
“The people who … did the most, they didn’t say they were going to do the most,” he said. “And there were other people who said they could do 150, and they did 70.”
Having a bit of humility helps make a good competitor, the trainer added.

Pushups and planks mark a “good general baseline” for measuring fitness level, according to Langowski. Some other basics include pull-ups, squats and endurance challenges, like running a mile — the kind of basics included in an elementary school fitness assessment.
For those who haven’t yet mastered these basics but want to get in better shape, Langowski shared some advice on how to get started.

“Get with a trainer or someone who knows how to progress you,” he advised. “A lot of people are like, ‘I can’t do a pushup, so I’m never going to do one.’ That’s not the way.”
Langowski recommends starting with pushups on your knees or against a wall, then gradually progressing to standard pushups by moving onto your toes and lowering yourself fully to the ground before pushing back up.

“You’ll be surprised after you do that for a couple weeks, a couple months, a couple years – you’re going to be able to do a lot,” he said. “Nobody was born being able to do 111 pushups. They put in the work and they started somewhere.”

The trainer noted that in addition to practicing, it’s just as important to give the body rest and to support muscle growth with proper protein intake and an overall healthy diet.
But perhaps the most crucial step toward getting in shape, according to Langowski, is having the motivation to get started

“I know that’s easy for me to say – I’ve been in fitness and been relatively fit most of my life,” he said. “And I know a lot of people are sitting on the couch and they either feel sorry for themselves or they’re going through a tough time … You’ve just got to get out there.”

The trainer suggested starting with a simple walk — even just around the block — with no gym equipment required.
“You don’t need an expensive gym membership to get in good shape,” he said. “Most of the people that I stop on the street, they don’t have a gym membership at all. They do it in their living room.”

“And that’s where you can do the exercises I mentioned – the squats, the lunges, the pushups,” Langowski went on.
“So, I would encourage people just to start, but also to get some friends or get a trainer, someone to support you and do it safely.”

Ancient Chinese movement shows promise for reducing blood pressure at home, study says
NEWYou can now listen to Fox News articles!
Researchers have shed fresh light on how a simple, centuries-old Chinese practice could be almost as effective as some medications in lowering blood pressure.
Baduanjin is a form of exercise that’s been widely practiced in China for at least 800 years. It involves a series of eight slow movements, gentle breathing and meditation — and typically takes only about 10 minutes to complete.
In a clinical trial, researchers studied 216 adults age 40 and older with Stage 1 hypertension. Over the course of a year, participants performed either baduanjin, self-directed exercise or brisk walking.
SIMPLE NIGHTLY HABIT LINKED TO HEALTHIER BLOOD PRESSURE, STUDY SUGGESTS
Researchers found that participants who practiced baduanjin five times per week experienced lower blood pressure within three months.
The results were “comparable to reductions seen with some first-line medications,” they wrote in their report published by the American College of Cardiology.

Baduanjin also showed “comparable results and safety profile to brisk walking at one year,” the researchers further reported.
“Given its simplicity, safety and ease at which one can maintain long-term adherence, baduanjin can be implemented as an effective, accessible and scalable lifestyle intervention for individuals trying to reduce their [blood pressure],” said the senior author of the study, Jing Li, M.D., Ph.D.
Dr. Matthew Saybolt, medical director of the Hackensack Meridian Jersey Shore University Medical Center’s Structural Heart Disease Program, said he was surprised by an aspect of the study’s results.
ANTI-AGING BENEFITS LINKED TO ONE SURPRISING HEALTH HABIT
“I was biased and expected that higher intensity exercise like brisk walking would have resulted in greater improvement in blood pressure than baduanjin, but the effects were the same,” Saybolt told Fox News Digital. (He was not affiliated with the study.)
Dr. Antony Chu, clinical assistant professor at Brown University’s Warren Alpert School of Medicine, was born and raised in the U.S. to immigrant parents — his mother is from Hong Kong and his father is from Taiwan.

Having spent a lot of summers in Asia, Chu told Fox News he experienced “the best of both worlds” concerning Eastern and Western medicine, including exposure to the benefits of baduanjin.
“[These researchers] are taking a lot of things that have been commonplace for many, many centuries or millennia and then just applying mathematical modeling and statistical analysis to sort of give [them] some credibility,” Chu said.

“Western medicine is reactionary,” Chu also said.
He compared the philosophies to a house on fire: Eastern medicine practitioners are more invested in preventing the fire, whereas Western medicine is more focused on “all those things that it would need to do to try to put that fire out,” he said, sharing his opinion.

Left untreated, high blood pressure has dangers that are “too numerous to count,” Saybolt said. The risks include increased risks of stroke, heart attack, atrial fibrillation and congestive heart failure.
Baduanjin, Chu said, is effective at reducing blood pressure, which he likened to “the water pressure and the pipes of your house,” by calming the nervous system and reducing stress.
SIMPLE DAILY HABIT MAY HELP EASE DEPRESSION MORE THAN MEDICATION, RESEARCHERS SAY
“People are totally stressed out,” Chu said. “And stress reduction is huge.”
Saybolt said the study offers hope for people with hypertension — “and that hope doesn’t immediately have to include pharmaceuticals.”

Saybolt added that he’s always advocated for lifestyle modifications, including healthy diet and exercise, “as key therapies for treatment of diseases and to improve longevity.”
With the baduanjin data, Saybold said he is now “more optimistic than ever,” as “we have evidence that a very low impact exercise with mindfulness can yield a benefit.”

Chu said that translating overwhelming medical guidelines is a big part of his job.
“It’s not to just tell somebody, ‘Hey, your blood pressure’s too high, pick a pill,” he said.

“Lifestyle changes” can be daunting for many people, he added.

“They always make it sound like you have to live for seven years in Tibet on a mountain somewhere, and it’s really not that.”

His simple translation for the baduanjin study is this: “Close the door in your office and just say, ‘I can’t be bothered for 10 minutes,’ and just focus on breathing slowly and moving your arms or legs around.”
