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 emerging COVID-19 BA.3.2 variant, dubbed Cicada and detected in 23 countries, may not pose a significant global threat, claimed a study.
The 2025 study, published in the mBio journal, showed that the immune response of the BA 3.2 COVID variant from vaccines or prior infection is less effective than against the original strain. The antibody effectiveness is three times lower against the BA.3.2 variant. However, it does not mean that there is no protection at all.
“BA.3.2 showed intermediate neutralization, representing a 3-fold reduction compared to the ancestral strain,” said the researchers from the Icahn School of Medicine at Mount Sinai, US.
“BA.3.2 occupied an intermediate but distinctly separate position,” they said, adding that the variant “shows substantial immune escape potential that threatens protection”.
In the study, the researchers used antigenic mapping to assess neutralizing antibody responses in 56 adults with varied exposure histories following KP.2 vaccination against emerging variants, including LP.8.1, LF.7.1, NB.1.8.1, XFG, and BA.3.2.
While KP.2 vaccination enhanced neutralization against homologous variants, substantial reductions in neutralizing activity were observed against emerging Omicron variants across all exposure groups.
Exposure history showed some influence on neutralization breadth, with self-reported vaccination-only participants exhibiting better cross-neutralization compared to individuals with hybrid immunity.
The findings highlight the ongoing challenge of maintaining vaccine effectiveness against evolving SARS-CoV-2 variants and argue for continuous updating of vaccines, the researchers said.
“Despite its extraordinary number of mutations, BA.3.2 is not able to overcome immunity from vaccination, finds study. Other variants were more capable of evading immunity. This indicates it is not a major real-world threat,” said Dr Rajeev Jayadevan, Ex-President of IMA Cochin and Convener of the Research Cell, Kerala, in a post on social media platform X. He was not part of the study.
BA.3.2 is a descendant of the Omicron BA.3 lineage. It is genetically distinct from the previously circulating JN.1 lineages (including LP.8.1 and XFG).
BA.3.2 comprises two major branches, BA.3.2.1 and BA.3.2.2. BA.3.2.2 also has substitutions like: K356T, A575S, R681H, and R1162P, the CDC report said.
What makes the BA.3.2 variant special is the “70 to 75 substitutions and deletions in the gene sequence of its spike protein”, according to the US CDC’s latest Morbidity and Mortality Weekly Report.
“BA.3.2 represents a new lineage of SARS-CoV-2, genetically distinct from the JN.1 lineages (including LP.8.1 and XFG) that have circulated in the US since January 2024,” said the CDC researchers.
“BA.3.2 mutations in the spike protein have the potential to reduce protection from a previous infection or vaccination,” they added.
However, the new Cicada variant with around 75 genetic changes in its spike protein is likely to disproportionately affect children, as per an expert, who noted its presence in the UK.
“Some people have done analysis on this, suggesting it may be more prevalent among young children. Children get infections all the time, but this might be something to do with the fact that they have never been exposed to Covid vaccines," Prof Ravindra Gupta, of Cambridge University, who advised the UK government during the pandemic, was quoted as saying to The Mirror.
“So this is something we’re looking at in the lab to try and work out why. The problem with this is that it is an infection that spreads fast. Eventually, it ends up in someone vulnerable," he added.
Symptoms seem to be similar to those of other recent variants and include
sore throat,
cough,
congestion,
fatigue,
headache
fever.
According to the CDC, the Cicada variant is also likely to raise gastrointestinal issues such as nausea or diarrhea.

The Jan Vishwas (Amendment of Provisions) Bill, 2026, passed by both Houses of Parliament, marks a significant step towards decriminalizing the health sector by amending certain provisions and boosting compliance.
The Union Health Ministry said that the Bill reflects the Government’s commitment to fostering a trust-based governance framework and ensuring proportionate regulation by reducing the compliance burden on individuals and businesses.
The reforms involving 23 Ministries rationalized over 1,000 offences across 79 Central Acts. These are aimed at helping advance Ease of Doing Business and Ease of Living across sectors.
It makes a key shift from criminal penalties to civil penalties as well as introduces adjudication mechanisms. The amendments ensure consistency, predictability, and proportionality in enforcement, the Ministry said.
Prime Minister Narendra Modi called the passing of the Jan Vishwas Bill by the Parliament "a matter of immense delight".
"This Bill strengthens a trust-based framework that empowers our citizens. It marks the end of rules and regulations that are outdated. At the same time, it ensures speedy disposal of cases, reduces litigation burden with decriminalization," PM Modi added.
Drugs and Cosmetics Act, 1940 -- to substitute imprisonment with financial penalties and to introduce a structured adjudication mechanism.
Pharmacy Act, 1948 -- to modernize penalty provisions and enhance accountability through increased financial penalties for non-compliance.
Food Safety and Standards Act, 2006 -- to strengthen enforcement while ensuring that penalties are proportionate to the nature of the offence.
Clinical Establishments (Registration and Regulation) Act, 2010 - to emphasize monetary penalties for non-compliance, particularly in cases where deficiencies do not pose immediate risks to patient safety.
National Commission for Allied and Healthcare Professions Act, 2021 -- to ensure compliance with professional standards and regulatory requirements, with penalties designed to deter violations while maintaining proportionality.
The Bill introduces a civil penalty framework to reduce the burden on courts, minimize layers of litigation, and enable faster resolution of minor compliance issues.

In the case of cosmetics, minor violations (other than spurious or adulterated) will not require court intervention and can instead be addressed through a civil penalty framework.
Further, violations such as non-maintenance of documents or non-submission of information, which were earlier punishable through court-imposed fines or imprisonment, can now be adjudicated through this civil penalty mechanism.
For the first time, the Act provides for the appointment of adjudicating authorities by the Central Government and State Governments, along with a defined process involving issuance of show cause notices, provision for personal hearing, and an appellate mechanism.
Union Health Minister JP Nadda noted that the Jan Vishwas Bill, "aims to remove outdated laws, reduce unnecessary legal burdens, and create a system that responds faster to people’s needs".
"These reforms will streamline operations for Indian medical devices manufacturers, enhance global competitiveness, and align with international best practices, ultimately benefiting patients and healthcare delivery across the country," Rajiv Nath, Forum Coordinator of The Association of Indian Medical Devices Industry (AiMeD).

The US Food and Drug Administration has recalled over three million eye drops in the country over safety concerns.
The 3,111,072 products were manufactured by California-based K C Pharmaceuticals and were sold under names such as “Dry Eye Relief Eye Drops,” “Sterile Eye Drops,” and “Artificial Tears Sterile Lubricant Eye Drops,” according to the FDA notice.
K C Pharmaceuticals made the voluntary recall of the eye drops in early March.
The eight types of eye drop products were sold at major retailers, including CVS, Walgreens, and Rite Aid. They have expiration dates ranging from April to October.
The FDA, in its Enforcement Reports, stated that the products recalled “lack of assurance of sterility.”
While so far, there are no reports of injuries associated with the eye drops, the FDA notice classified the action as a “Class II recall.”
Class II recalls apply to products that can cause “temporary or medically reversible” health problems.
As per the FDA, "the probability of a serious health issue is remote," over these products, and that is why the recall is categorized as a Class II, USA TODAY reported
"Patients and consumers can continue using the medicine unless otherwise directed by the recalling company or FDA," the regulator said in a statement to the publication.

The key to ensuring that your eyes are protected from environmental factors like the sun, dust, and dirt, especially for those who work outdoors or spend long hours on screen, is investing in good sunglasses with ultraviolet protection.
"For those who are using computers a lot, you need to blink your eyes constantly, take breaks in between, and drink a lot of water. Dehydration is also a contributing factor to dry eye," Dr Anita Sethi, who is Principal Director and HOD Ophthalmology, Max Multi Specialty Centre at Panchsheel Park.
She also recommends using zero-number protective glasses and computer glasses that can decrease strain and dry eye.
While advising people to stay away from natural remedies like turmeric or ginger put inside the eye, Dr Sethi urged people to consume more “foods rich in vitamin E, antioxidants” to maintain eye health.
“Colored vegetables and fruits, and even maintaining thyroid and vitamin D levels, because these also contribute to dry eye,” the ophthalmologist said.
