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)?

"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.

English actor and former Blue Peter presenter Peter Duncan recently urged health authorities to make focal therapy more available for prostate cancer patients. He said after describing the treatment as "life-changing" following his own diagnosis in 2019.

This comes as new evidence has been emerging that the minimally invasive approach can offer satisfactory cancer control compared to traditional treatments, while also significantly reducing long-term side effects.

The 72-year-old broadcaster revealed that he was initially offered a prostatectomy, a surgery that removes the entire prostate gland. Instead, he opted for focal therapy, a targeted treatment that destroys only the cancerous portion of the prostate while preserving healthy tissue.

"It was a complete success, and I've only experienced very minor after-effects, allowing me to continue with my life as before," Duncan said, while backing Prostate Cancer UK's campaign for wider NHS access to the treatment. "Many men aren't given the same chance I was, and that needs to change."

Duncan's campaign comes amid growing clinical evidence supporting focal therapy for selected patients with localised prostate cancer.

A recent report from researchers at Imperial College London and Imperial College Healthcare NHS Trust found that focal therapy shows promise in cancer treatment compared to surgery and radiotherapy while causing far fewer complications in some patients.

Amy Rylance, Director of Health Services, Equity and Improvement at Prostate Cancer UK, said the delay in wider approval is leaving thousands of men with no access to treatments that could preserve their quality of life.

"Without a timeline from NICE, we simply don't know how long men will have to wait for approval on the NHS," she said. "Thousands of men will have to deal with life-changing side effects simply because of their postcode."

Unlike prostatectomy or radiotherapy, focal therapy targets only the tumour inside the prostate. The treatment may use high-intensity focused ultrasound (HIFU) or cryotherapy to destroy cancer cells while preserving the surrounding healthy tissue.

Because the rest of the prostate and surrounding nerves are preserved, patients may generally face a much lower risk of urinary incontinence, erectile dysfunction and bowel problems.

Focal therapy is not suitable for everyone. Specialists say it is generally considered for men with localised, clinically significant prostate cancer where imaging and biopsy show that the tumour can be accurately targeted.

Patients still require long-term monitoring after treatment to ensure the cancer has not returned or progressed.

Can Focal Therapy Help?

Prostate cancer is the most commonly diagnosed cancer in men in the UK. According to Prostate Cancer UK, around one in eight men will be diagnosed during their lifetime, with the risk increasing with age, family history and Black ethnicity.

While surgery and radiotherapy remain the standard treatment options to treat prostate cancer, advocates argue that expanding access to focal therapy could help thousands of eligible men receive effective treatment with fewer long-term side effects.

Duncan hopes sharing his own experience will encourage both policymakers and patients to consider the option where appropriate.

In a first for India, Maharashtra has allowed qualified homeopathy practitioners to prescribe certain modern medicines after completing a one-year Certificate Course in Modern Pharmacology (CCMP).

The decision has sparked strong opposition from the Indian Medical Association (IMA) and several doctors' bodies, which have announced protests, citing concerns over patient safety, medical education, and professional standards.

What Is The Debate All About?

Under a Government Resolution (GR) issued on August 3, Maharashtra has allowed BHMS graduates who have completed the one-year Certificate Course in Modern Pharmacology (CCMP) to register with the Maharashtra Medical Council (MMC). The registration allows eligible practitioners to prescribe specified modern medicines under the state's policy.

The MMC began registering CCMP-qualified practitioners on August 5. According to reports, one practitioner has been registered so far, while around 2,500 applications remain pending.

The IMA has warned of a nationwide strike if the Maharashtra government does not withdraw its decision. In a letter to Maharashtra Chief Minister Devendra Fadnavis, signed by IMA National President Dr. Anilkumar J. Nayak and Secretary General Dr. Sarbari Dutta, the association demanded immediate withdrawal of both the GR and the CCMP course.

Why Is the IMA Objecting?

The IMA has raised the following concerns:

• No approval from national regulators:

• Opposition to dual registration:

• Matter pending before the court

• Concerns over medical education

What Is the CCMP Course? Why Was It Introduced?

The Certificate Course in Modern Pharmacology (CCMP) is a one-year program introduced in Maharashtra in 2016 by the Maharashtra University of Health Sciences (MUHS). It is designed for BHMS (Bachelor of Homeopathic Medicine and Surgery) graduates and trains them in aspects of modern pharmacology and allopathic medicine.

The CCMP course was introduced following a major agitation by homeopathic associations, including a 13-day indefinite hunger strike in Nagpur in 2013, demanding legal rights to prescribe essential modern medicines.

According to the Maharashtra government, the objective was to strengthen healthcare delivery, particularly in areas facing shortages of doctors.

To facilitate the course, the state amended the Maharashtra Homoeopathy Practitioners' Act, 1960 and the Maharashtra Medical Council Act, 1965 in 2014, after the legislation was passed by both Houses of the State Legislature.

The IMA now argued that the situation in 2014 when the MMC Act was amended is very different from the situation now.

The medical body cited the cancellation of "bond system for MBBS graduates due to the nonavailability of vacant posts for them even in rural areas- signifying sufficient availability of MBBS doctors".

What Does the CCMP Course Include?

According to the government, the one-year CCMP curriculum was developed by expert committees at MUHS after comparing the BHMS and MBBS syllabi to bridge gaps in training.

The course includes:

• Training in modern pharmacology
• Practical laboratory procedures
• Rotational hospital training in clinical subjects of allopathy
• Teaching at government and private medical colleges
• Examinations conducted by the Faculty of Medicine, MUHS

The government says the program is intended to make registered homeopathic practitioners competent to prescribe specified modern medicines and improve access to healthcare in the state.

But the IMA has argued that such "short-term certification or bridge courses cannot substitute for comprehensive medical education". They also warned that permitting cross-practice would compromise patient safety.

What's Next?

The Maharashtra Association of Resident Doctors (MARD) began an indefinite statewide strike on August 3. On August 5, doctors across Mumbai withdrew routine outpatient department (OPD) services in protest against the government's decision.

Doctors from Pune are scheduled to join their counterparts in Mumbai for demonstrations at Azad Maidan on August 6. The IMA has warned of a nationwide strike if the Maharashtra government does not withdraw the decision. The IMA Kerala State Branch has also extended support to the Maharashtra doctors' protest.

A severe COVID-19 infection may awaken dormant viruses that remain hidden in the body for life, even in people with otherwise healthy immune systems, according to a study published in Nature.

The study, which analyzed more than 1,100 hospitalized COVID-19 patients, found that viral reactivation was common and may contribute to long COVID symptoms. Researchers said the findings suggest COVID-19 can disrupt the body's internal ecosystem of dormant viruses, creating a state they describe as "dysvirosis."

"This finding suggests that COVID-19 may not always act as a single viral infection and may disrupt the body's internal ecosystem of dormant viruses, creating a state of 'dysvirosis'," said lead author Cole Maguire from Dell Medical School at The University of Texas at Austin.

Which Dormant Viruses Were Reactivated?

Nearly half of the hospitalized patients had at least one dormant virus reactivate during their COVID-19 illness. The viruses identified included:

• Epstein-Barr virus (EBV), which causes mononucleosis
• Herpes family viruses
• Enteroviruses
• Cytomegalovirus (CMV)
• Herpes simplex virus-1 (HSV-1)
• Human herpesvirus-6 and -7 (HHV-6/7)
• Anelloviridae, a lesser-known family of chronic viruses

How Viral Reactivation Affects The Body

The researchers found that viral reactivation was more common in patients with severe COVID-19 and those who had longer hospital stays, and caused:

• Increase inflammation
• Worsened tissue injury
• Prolonged recovery

The study also noted that these viruses have previously been linked to autoimmune conditions such as multiple sclerosis and lupus.

Further, the study found that dormant viruses do not reactivate simultaneously after SARS-CoV-2 infection.

• Epstein-Barr virus and anelloviruses tended to reactivate early, shortly after hospital admission.
• Cytomegalovirus and herpes simplex viruses generally emerged around three weeks later, primarily in the respiratory system.

Not Limited to People With Weak Immune Systems

Earlier research had mainly observed viral reactivation in people with weakened immune systems. However, this study found that reactivation frequently occurred in people who were healthy before developing COVID-19.

According to the researchers, this suggests viral reactivation may be more common than previously believed and could contribute to worse outcomes even in otherwise healthy individuals.

While the study does not prove that viral reactivation causes long COVID, it provides strong evidence that dormant viruses may contribute to the condition.

Researchers found that Anelloviridae appeared more frequently in patients with long COVID who experienced persistent fatigue and reduced physical function.

"Our findings have important implications for patient care. Tests already exist for several of the chronic viruses studied, and some viruses in the herpes family can be treated with existing antiviral drugs," said study principal investigator Melamed, assistant professor of neurology at Dell Medical School.

"The next step is determining whether identifying and treating reactivated viruses can improve outcomes for patients with acute COVID-19 and long COVID."

The study may also influence future treatment strategies. Researchers noted that, instead of targeting only SARS-CoV-2, clinicians may eventually be able to use existing antiviral drugs against reactivated viruses, particularly herpesviruses.

A Phase II clinical trial is already underway to evaluate antiviral therapies targeting herpesviruses in people with long COVID.
