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."

What is Atrial Fibrillation (A-Fib)?

A-Fib is a heart condition that affects the upper chambers of the heart, known as the atria. When these chambers beat irregularly, blood can pool and form clots, increasing the risk of stroke. Stroke is one of the most serious complications associated with A-Fib, and smoking is known to exacerbate this risk.

"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.

Tips for Quitting Smoking

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. government's Department of Health and Human Services (HHS) recently announced partnering with the Department of Veterans Affairs (VA) to fast-track the development of psychedelic-assisted therapies to treat veterans living with mental health issues like post-traumatic stress disorder (PTSD), depression, traumatic brain injury (TBI), and more.

After years of interest, 2026 has marked a major policy shift, with the White House, Congress, and the Department of Veterans Affairs (VA) all actively participating in accelerating research into treatments like psilocybin, MDMA, and ibogaine.

“America owes every veteran the best care our nation can provide,” said HHS Secretary Robert F. Kennedy, Jr. “We’re not going to wait while promising treatments sit on the sidelines. Thanks to President Trump’s leadership, HHS and the VA are working together to develop safe, FDA-approved innovations and transition them from research into care so veterans can access the treatments they deserve.”

The collaboration comes as a bipartisan group of lawmakers introduced a new bill in Congress that would require the U.S. Department of Defense to evaluate how ongoing psychedelic research, particularly those involving psilocybin, could benefit service members who are active on duty and veterans transitioning back to civilian life.

“President Trump opened up a world of possibility for treating Veterans and others with mental health conditions, and VA is proud to be part of this important work,” said VA Secretary Doug Collins. “Today’s MOU ensures effective cooperation with HHS as we try to turn research into life-changing treatment.”

Initiative To Accelerate Treatments For Mental Illnesses

The initiative was accelerated this year in April when President Donald Trump signed an executive order directing federal agencies to ramp up research, regulatory review, and appropriate patient access ways for psychedelic medicines targeting serious mental illnesses.

According to the White House, the goal is to expand the scope of scientific research while ensuring safety and regulatory requirements, rather than recklessly legalizing psychedelic drugs for general medical use.

Most psychedelic compounds, including psilocybin, MDMA, and ibogaine, remain classified as Schedule I substances under federal law.

Mental Health Challenges Faced By Veterans

Mental health challenges remain one of the most pressing issues U.S. veterans face after their military service. They are prioritised because they face a disproportionately high burden of PTSD, depression, suicide, and traumatic brain injury among former service members.

While conventional treatments, including antidepressants and psychotherapy, help many patients, a substantial number do not achieve lasting relief.

Researchers hope psychedelic-assisted therapy, administered under carefully supervised clinical settings alongside psychotherapy, may offer another option for people who are still struggling despite existing treatments.

Growing Interest In Psychedelic Medicine

The interest in psychedelic medicine has grown rapidly over the past decade. Studies have suggested that MDMA-assisted psychotherapy may help alleviate PTSD symptoms in some patients, while psilocybin-assisted therapy has shown promise for treatment-resistant depression in clinical trials.

These therapies differ from recreational drug use because they involve carefully screened patients, controlled doses, trained therapists, and structured treatment plan and follow-up sessions.

El Salvador Becomes First Country In Central America To Eliminate Trachoma: WHO

Updated Jul 14, 2026 | 11:00 AM IST

SummaryTrachoma is a bacterial eye infection caused by Chlamydia trachomatis. It can spread from person to person through contaminated fingers, fomites and flies that could come into contact with discharge from the eyes or nose of an infected person.

The World Health Organization (WHO) has validated El Salvador for eliminating trachoma, the world's leading infectious cause of blindness, as a public health problem.

El Salvador is the first country in Central America and the second in the Americas to achieve this milestone.

"I congratulate El Salvador on this remarkable achievement. It is a testament to the power of political commitment, strategic investment, and community engagement," said WHO Director-General Dr Tedros Adhanom Ghebreyesus.

"El Salvador's success is a vital step towards our global target of eliminating trachoma worldwide by 2030 and a clear signal that a healthier, more equitable future is within reach," he added.

Between 2023 and 2026, El Salvador conducted targeted assessments in communities identified as at higher environmental and social risk. The surveys found no evidence of active trachoma transmission.

As per the WHO, "no cases of active disease were detected in children, and no adults were found to have advanced trachoma capable of causing blindness". These findings confirmed that trachoma is no longer a public health problem in the country, the UN health agency said.

El Salvador's achievement was supported by a coordinated approach that included:

  • Strengthening primary healthcare services
  • Improving water, sanitation and hygiene (WASH)
  • Expanding eye health services, including adult vision screening
  • Collaboration between government agencies, communities and international partners

The country has also established trained health personnel, integrated surveillance systems and the capacity to detect and treat trichiasis—the advanced stage of trachoma in which eyelashes turn inward and can lead to blindness.

What Is Trachoma?

Trachoma is a bacterial eye infection caused by Chlamydia trachomatis. It can spread from person to person through contaminated fingers, fomites and flies that could come into contact with discharge from the eyes or nose of an infected person.

Environmental risks like poor hygiene, overcrowded households, and inadequate access to water and sanitation facilities can also lead to trachoma.

Repeated infections can scar the inner eyelid, causing the eyelashes to turn inward—a condition known as trichiasis. Without treatment, the eyelashes scratch the surface of the eye, potentially leading to irreversible blindness.

Trachoma Still Persists In Parts Of The Americas

Although El Salvador has eliminated trachoma as a public health problem, the disease remains endemic in rural and remote areas of Brazil, Colombia, Guatemala and Peru.

WHO recommends that countries maintaining elimination continue surveillance and ensure access to quality eye care services to prevent the disease from re-emerging.

WHO Criteria For Elimination

WHO defines elimination of trachoma as a public health problem based on three key criteria:

  • Trichiasis prevalence of less than 0.2% among people aged 15 years and older.
  • Active trachoma (trachomatous inflammation–follicular) prevalence of less than 5% among children aged 1–9 years in every previously endemic district.
  • A functioning health system capable of identifying and managing new trichiasis cases.

With this achievement, El Salvador joins 64 countries worldwide that have been validated by WHO for eliminating at least one neglected tropical disease. Seven of these countries are in the Americas.

US Appeals Court Revives Over 500 Tylenol Lawsuits Over Autism Claims

Updated Jul 14, 2026 | 11:08 AM IST

SummaryThe lawsuits gained attention after President Donald Trump and Health and Human Services Secretary Robert F. Kennedy Jr. issued guidance last year discouraging pregnant women from using acetaminophen, citing it as a possible contributor to autism.

While there is no firm scientific evidence linking Tylenol use during pregnancy to autism, a US federal appeals court has revived more than 500 private lawsuits against the painkiller's maker, Kenvue, over claims that prenatal exposure to acetaminophen contributed to autism and attention-deficit/hyperactivity disorder (ADHD) in children.

The ruling does not determine that Tylenol causes autism or ADHD. Rather, it held that expert testimony supporting the plaintiffs should not have been excluded from the lawsuits.

What Did The US Appeals Court Say

On July 13, the 2nd US Circuit Court of Appeals in Manhattan overturned a December 2024 ruling by US District Judge Denise Cote, who had dismissed the lawsuits after rejecting the methodology of the plaintiffs' expert witnesses.

In its 64-page decision, the three-judge panel said the district court had improperly excluded expert testimony from three doctors presented by parents and guardians seeking to link prenatal Tylenol use with autism and ADHD.

Circuit Judge Guido Calabresi wrote that the experts' methods reflected approaches used by other scientists and "constitute acceptable interpretations of scientific evidence where scientists may, and in fact do, disagree."

Court Did Not Rule That Tylenol Causes Autism

The appeals court emphasized that it was not deciding whether acetaminophen causes autism or ADHD, nor was it making any public health determination.

Instead, the ruling focused solely on whether the expert testimony met the legal standards required to be considered in court.

The three experts whose testimony was reinstated include:

  • Andrea Baccarelli, Dean of Harvard University's School of Public Health
  • Eric Hollander, Professor of Psychiatry at Albert Einstein College of Medicine
  • Brandon Pearson, Toxicologist at Columbia University

Ashley Keller, a lawyer representing the families, said the panel unanimously found that the experts had reliably applied accepted scientific methods.

Kenvue Defends Tylenol's Safety

Kenvue, which was spun off from Johnson & Johnson in 2023, said it continues to stand by the safety of Tylenol.

"We stand behind the safety of our product and will continue to defend these cases," the company said in a statement.

Several retailers and pharmacy chains—including CVS, Kroger, Target, Walgreens, and Walmart—have also been named as defendants.

Trump Administration's Remarks Sparked Debate

The lawsuits gained attention after President Donald Trump and Health and Human Services Secretary Robert F. Kennedy Jr. issued guidance last year discouraging pregnant women from using acetaminophen, citing it as a possible contributor to autism.

The remarks triggered concern among expectant mothers and prompted criticism from many healthcare experts and medical organizations, which said the evidence does not support such definitive claims.

Is Acetaminophen Linked to Autism or ADHD?

The scientific evidence remains inconclusive. Some observational studies have reported a possible association between prolonged acetaminophen use during pregnancy and an increased risk of autism or ADHD in children. However, many other studies have found no significant link.

Importantly, an association does not prove that acetaminophen causes these conditions. Researchers note that factors such as maternal illness, genetics, underlying medical conditions, and other environmental influences may also affect a child's neurodevelopment.

As a result, experts say more high-quality research is needed before any causal relationship can be established.

What Do Medical Experts Recommend?

Major medical associations continue to consider acetaminophen the preferred pain reliever and fever reducer during pregnancy when used appropriately.

Doctors advise pregnant women to:

  • Use the lowest effective dose for the shortest necessary duration.
  • Avoid prolonged or unnecessary use without medical advice.
  • Consult their healthcare provider before taking any medication during pregnancy.

Medical societies have also cautioned against avoiding acetaminophen altogether, noting that untreated high fever or severe pain during pregnancy can pose risks to both the mother and the developing baby.
