How Quitting Smoking Can Quickly Lower Risk Of A-Fib
Smokers who make the decision to quit will experience immediate health benefits, including a rapid reduction in their risk of atrial fibrillation (A-Fib), according to new research published in JACC: Clinical Electrophysiology. The study, conducted by Dr. Gregory Marcus, a cardiologist at the University of California, San Francisco, offers compelling evidence for smokers to quit, showing that it’s never too late to avoid the damaging effects of smoking on heart health.
Dr. Marcus, the senior author of the study, emphasized that A-Fib can be prevented even in individuals who have smoked for years. "The findings provide a compelling new reason to show current smokers that it’s not too late to quit, and that having smoked in the past doesn’t mean you’re ‘destined’ to develop A-Fib," Marcus explained. "Even for the current and longtime smoker, A-Fib can still be avoided."
"There’s strong evidence that smoking increases the risk of A-Fib," Marcus said. "But the benefits of quitting smoking have been less certain." With this in mind, his team sought to determine whether quitting could significantly lower a person’s risk of developing A-Fib, or if the risk would remain the same.
The research team analyzed data from over 146,700 current and former smokers, tracking their smoking habits and health over a 12-year period using data from the UK Biobank database. The results were promising: former smokers had a 13% lower risk of developing A-Fib compared to current smokers, while those who quit during the study saw an 18% reduction in their risk.
"This is likely a testament to the potency of reducing atrial fibrillation risk pretty shortly after quitting," Marcus said in a statement from the American College of Cardiology.
The findings highlight the importance of quitting smoking, not only for general health but specifically for reducing the risk of serious heart conditions like A-Fib.
Quitting smoking is one of the most effective ways to lower the risk of A-Fib and improve overall heart health. While it can be challenging, the benefits of quitting are clear and immediate. Here are some tips to help you quit smoking successfully:
1. Choose a specific date to quit smoking and stick to it. Prepare yourself mentally and physically for this change.
2. Reach out to family, friends, or a support group to help keep you accountable. Sharing your goals with others can provide encouragement.
3. Options like nicotine patches, gum, or lozenges can help ease withdrawal symptoms and reduce cravings.
4. Identify situations that make you want to smoke, such as stress or social gatherings, and find healthy ways to cope with them.
5. Regular exercise can help distract you from cravings and improve your mood during the quitting process.
6. Drinking water can help flush nicotine out of your system faster, reducing cravings.
7. Activities like yoga, meditation, or deep breathing exercises can help manage stress, a common trigger for smoking.
Quitting smoking offers immediate and significant benefits, particularly in reducing the risk of atrial fibrillation. The latest research provides smokers with more motivation to quit, showing that it's never too late to take control of their heart health.

The U.S. Centers for Disease Control and Prevention is promoting a long-debunked theory, suggesting a potential link between vaccines and autism, and claiming that studies supporting this connection “have been ignored by health authorities.”
The disputed theory appeared on a revised section of the CDC’s website under “Autism and Vaccines” on Wednesday. The website now states: “The statement ‘Vaccines do not cause autism’ is not an evidence-based claim. Scientific studies have not ruled out the possibility that infant vaccines contribute to the development of autism.
However, this statement has historically been shared by the CDC and other federal health agencies within HHS to prevent vaccine hesitancy.” The agency added that the U.S. Department of Health and Human Services has “launched a thorough review of the causes of autism, including investigations on plausible biological mechanisms and potential causal links.”
It also noted, “This webpage will be updated with gold-standard science.” Prior to Wednesday, the page stated there is “no link” between vaccines and autism, and no vaccine ingredients were connected to the condition, according to archived versions cited by The Washington Post.
Another part of the site, “About Vaccines for Your Children,” last updated in August 2024, still asserts, “Scientific studies and reviews continue to show no relationship between vaccines and autism.” Dr. Demetre Daskalakis, a former CDC official who resigned earlier this year as head of the National Center for Immunization and Respiratory Diseases, criticized the changes, saying on X, “The weaponization of the voice of CDC is getting worse. DO NOT TRUST THIS AGENCY. This is a national embarrassment.” Despite the new language, the header “Vaccines do not cause autism” remains due to an agreement with Sen. Bill Cassidy (R-La.), chair of the Senate Health Committee, who cast the deciding vote to advance Health Secretary Robert F. Kennedy Jr.’s nomination to the full Senate floor.
The revisions surprised CDC staff, including those overseeing vaccine safety and autism information, leaving them blindsided, according to The Post. “We just saw it, and everyone is freaking out,” one scientist said, as per NBC News.
While the changes could undermine public confidence in vaccines, Kennedy and Trump have historically supported this theory. Both have also warned against Tylenol use during pregnancy, claiming a link to autism, despite large-scale studies disproving any connection.
Autism spectrum disorder, or autism, is a condition that affects the brain, making it challenging for some people to communicate and interact with others. Experts still don’t fully understand what causes it.
The idea that vaccines might play a role largely began with a 1998 study suggesting that the MMR (measles-mumps-rubella) vaccine—or infection with the natural measles virus—could lead to autism. Since then, numerous scientific studies have shown there is no connection between vaccines or any of their ingredients and autism.
The 1998 study itself was later discredited: the research was found to be false, the doctor responsible lost his medical license, and the journal that published the paper retracted it, acknowledging it should never have been published.
Despite strong evidence showing vaccines are safe and effective, some parents still choose to delay or skip vaccinations for their children. This can be very dangerous, as diseases like measles, which vaccines prevent, are still circulating. An unvaccinated child who contracts one of these illnesses can become seriously ill or even die and may also put others at risk.
While mild reactions like a fever or rash can occur after vaccination, the chance of a serious side effect from the MMR or other recommended vaccines is very small compared to the risks of the diseases they protect against.

A major claim from China has sparked global curiosity and debate after a Shenzhen-based biotechnology company announced that it has developed a longevity pill capable of significantly slowing ageing.
A biotechnology company in Shenzhen, China, has caught worldwide attention by claiming to have created a pill that could dramatically slow the ageing process. According to the firm, the pill may one day help humans live up to 150 years by targeting ageing at the cellular level.
As per The Independent, Lonvi Biosciences says its formula focuses on ‘zombie cells’—aged cells that refuse to die, causing inflammation and age-related illnesses. Let’s take a closer look at the pill and explore whether this ambitious claim could be possible.
The Shenzhen-based company, part of China’s rapidly growing longevity industry, claims it has produced a pill that could theoretically stretch human life to 150 years. The formula targets so-called “zombie cells”—older cells that resist dying, leading to inflammation and disease associated with ageing. “This is not just another pill. This is the Holy Grail,” said CEO Ip Zhu, calling the capsule a breakthrough that could make extreme longevity achievable. The main ingredient comes from grape seeds and has shown in lab studies to extend lifespan in animals by delaying age-related diseases. Lonvi’s researchers suggest that taking the pill in adulthood could push life expectancy past 120, while starting from birth could surpass 150.
The pill contains procyanidin C1 (PCC1), a compound extracted from grape seeds. In experiments with mice, Lonvi claims the treatment increased overall lifespan by 9.4%, with a remarkable 64% improvement when dosing started from the very beginning. Lyu Qinghua, Lonvi’s chief technology officer, told The New York Times that reaching 150 is “definitely realistic” and could be possible “within a few years.”
China has made anti-ageing research a national priority, with President Xi Jinping reportedly discussing it with Russian President Vladimir Putin. Anti-ageing research, combined with AI and biotech, has quickly moved from niche interest to mainstream focus in the country.
A study in Nature Metabolism showed that procyanidin C1 from grape seed extract successfully extended both the lifespan and health span of mice, paving the way for future clinical trials.
Cellular senescence plays a key role in ageing, occurring when cells can no longer perform their functions. In recent years, researchers have identified drugs called senolytics, which can eliminate these senescent cells in the lab and in animal studies. This approach is an important step toward reducing age-related chronic diseases and could play a critical role in extending lifespan.
While the company’s claims have not yet been tested in human trials, scientists believe the approach holds promise for extending life. Lonvi’s researchers say the PCC1 pill can boost cellular health, delay deterioration, and maintain energy production over time. They suggest that when combined with a healthy lifestyle, the pill could help people live beyond 100, and possibly even past 120, while also reducing diseases linked to ageing.

A cheese brand has recalled one of its products over a serious health risk. Face Rock Creamery LLC has announced a voluntary recall of its Vampire Slayer Garlic Cheddar, according to a recent notice shared by the United States Food and Drug Administration. The decision came after the FDA detected Listeria monocytogenes in the area where the cheese was packed. The cheese is being pulled from shelves due to listeria contamination, which has also been linked to recent deaths in the United States, as reported by The Independent.
Only 16 units of the affected cheese were sold at the Face Rock flagship outlet at 680 2nd St. SE, Bandon, Oregon. Shoppers can identify the recalled product by its UPC code 8 512222 00547 8, according to the FDA.
These six ounce blocks were sold between November 10 at 3:30 p.m. PT and November 13 at 3:30 p.m. PT. Although no illnesses have been confirmed so far, customers who purchased the cheese are advised to discard it or bring it back to the store for a complete refund.
The item under recall is the Vampire Slayer Garlic Cheddar with a use by date of November 4, 2026, and the UPC 8 512222 00547 8. Face Rock Creamery stated that it is committed to strict food safety practices and transparency and that it is cooperating with authorities while taking immediate action to secure its production setting, according to The Independent. As of November 18, the FDA had not received any reports of illness tied to this cheese.
The recall notice on the FDA website explains that listeria infections can be dangerous and may be fatal for young children, older adults, and individuals with weakened immunity. It also states that healthy people might experience short-term problems such as high fever, strong headache, stiffness, nausea, stomach pain and diarrhea. For pregnant women, listeria can lead to miscarriages or stillbirths.
Listeria is a bacteria found in soil, water and animals that can contaminate food and cause listeriosis, a serious infection, as per World Health Organization. It poses a higher risk for pregnant women, newborns, older adults and people with weakened immune systems because it can live and grow even at refrigerator temperatures.
People usually become sick after eating contaminated items such as soft cheeses, deli meats or unpasteurized milk. Symptoms may be mild or flu-like, but the infection can lead to dangerous problems, including meningitis.
In the United States, listeria is the third leading cause of death linked to foodborne illness and is responsible for about 260 deaths each year. Many food products have been recalled in the past few months due to listeria concerns. As per USA Today, six people have died in a multistate outbreak connected to recalled prepared pasta dishes sold at large chains including Albertsons, Kroger, Sprouts Farmers Market and Trader Joe’s.
Federal officials reported at least 27 infections across 18 states, and CNN noted that a pregnant woman lost her fetus after becoming sick.
Symptoms of listeriosis often begin with fever, chills, muscle pain, nausea or diarrhea. In more severe cases, the infection can spread beyond the digestive system and may cause intense headache, stiff neck, confusion, seizures and widespread infection that leads to organ failure. Pregnant women may have only mild flu-like signs, yet the infection can cause serious harm to the developing fetus.
