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.

As many as 125 doctors, nurses and public health professionals are contesting the November 3 US midterm elections, marking an unprecedented level of participation by healthcare professionals in electoral politics, according to a media report.

Among the prominent candidates are Dr Amy Acton, Dr Abdul El-Sayed and former US Health and Human Services (HHS) Secretary Xavier Becerra.

Many of these candidates entered the political spotlight during or after the COVID-19 pandemic. They are now seeking elected office to influence public health funding, vaccination policies, healthcare access, and the Trump administration’s approach to science and medical research.

“I haven’t seen anything exactly like this before,” historian Dr Kristoffer Shields, director of the Eagleton Center on the American Governor at Rutgers University, told CNN. “The link between science and politics has always been sort of weak.”

A separate review by Becker’s Hospital Review identified at least 58 physicians, nurses and other clinicians running for governor or Congress. The group includes 29 physicians, 16 nurses, four pharmacists, four dentists and five other healthcare professionals. Of these, 46 are contesting House seats, eight are running for the Senate and four are seeking governorships.

Few Healthcare Professionals In US Congress

Healthcare professionals currently remain a small minority in American politics. The US Senate has four doctors, all Republicans: John Barrasso of Wyoming, Bill Cassidy of Louisiana, Roger Marshall of Kansas and Rand Paul of Kentucky.

The House of Representatives includes 17 physicians, four dentists, two pharmacists, one nurse practitioner, one optometrist and one rehabilitation therapist.

Concerns Over Science and Public Health

Concerns about the Trump administration’s approach to science and public health have become a key reason for healthcare professionals to seek political office.

Other important concerns include the dismissal of federal doctors and scientists, cuts to research funding, removal of government datasets and public health websites, and changes affecting measures such as water fluoridation and childhood vaccination.

“Our country should be great. Our country should be pro-science, pro-innovation, and science keeps us safe. It protects us. It leads to wonderful discoveries, and this administration has completely burned all of that down,” Dr Kristin Hook, a former staffer at the National Institutes of Health (NIH) and the US Government Accountability Office, told CNN.

Hook, who lost her 2024 bid as a Democrat for Texas’ 21st Congressional District, is contesting the same seat again this year.

Becerra, contesting the California gubernatorial election against Republican candidate Steve Hilton, warned that weakening public health institutions could make the country more vulnerable to natural disasters and pandemics.

“HHS is not a place for science deniers or science skeptics. Why would you get rid of some of our best scientists and doctors and health professionals?” he told CNN.

How COVID-19 Changed Health and Politics Equation

The COVID-19 pandemic brought public health officials into the political spotlight, as decisions on restrictions, vaccines and other health measures became subjects of intense public debate.

Some officials also faced threats and harassment, while others left their positions, prompting healthcare professionals to consider a more direct role in policymaking.

The death of Irish Olympic runner and European champion Ciara Mageean at the age of 34 has sparked concerns about bowel cancer among young people. In fact, Bowel Cancer Ireland has urged the national bowel cancer screening age to be lowered for early detection and prevention.

Mageean died on November 1, 2026 after being diagnosed with stage four bowel cancer in July 2025. The athlete had collaborated with Bowel Cancer Ireland after her diagnosis to spread awareness about the disease.

Bowel Cancer Risk In Young People

Around one in 10 bowel cancer diagnoses in Ireland occur in people under the age of 50. However, the country's national BowelScreen programme currently offers screening to people aged 57 to 71.

Brendan Donlon, chair of Bowel Cancer Ireland, told RTÉ's Morning Ireland that the screening age needs to be lowered and that the country must implement more policies to improve early detection.

"The death of Ms Mageean is a strong reminder that you can never be too fit or too young to be affected by bowel cancer," he said.

Donlon also spoke about the difference in screening ages in Ireland and other countries. He said the screening age was 45 in Australia, 50 in the UK and 45 in the US, compared with 57 in Ireland.

Although Ireland's Minister for Health has approved a recommendation to extend screening to people aged 50 to 54, Donlon said there was no clear timeline, budget or sufficient testing capacity to implement the change.

Ireland Being Urged To Lower Its Bowel Cancer Screening Age

Bowel Cancer Ireland has been campaigning for earlier screening as cases among younger adults become an increasing concern. BowelScreen provides a free, at-home bowel screening test every two years to eligible people aged 57 to 71. The test is designed to detect signs of bowel cancer before symptoms develop.

In April 2026, Ireland's Minister for Health approved a recommendation to extend screening for people aged 50 to 54. However, the Health Service Executive (HSE) has said that the expansion depends on completing the current programme expansion and increasing healthcare capacity. The proposed timeline assumes implementation from 2031.

The expansion is expected to make more than 400,000 additional people eligible for screening and could require more than 2,700 additional colonoscopies each year.

Donlon said the availability of colonoscopy services was already a concern, pointing to 6,700 people who were waiting for urgent colonoscopy in the previous year. He also said that bowel cancer screening is essential as it can identify precancerous growths that can be removed before they develop into cancer.

He said, "It (bowel cancer) is a very survivable cancer. It's one of the most treatable cancers if caught early and unfortunately one of the most lethal when caught late. That's why we have to focus our attention on raising awareness of symptoms, but also getting the Government to focus on lowering the screening age."

Bowel Cancer Symptoms In Younger Adults May Be Overlooked

Bowel Cancer Ireland has urged people to recognise warning signs and seek medical advice rather than dismissing certain symptoms. According to Donlon, symptoms that should be assessed include:

• Blood in the stool, which may appear red or make stools look black
• Constant changes in bowel habits, including changes in stool consistency, size, shape or frequency
• Weight loss due to no reason
• Constant abdominal pain or bloating
• Tiredness that does not go away with rest or sleep

He advised people to seek medical attention if changes in bowel habits continue for three weeks.

He also raised concerns that symptoms in younger women may sometimes be attributed to premenstrual syndrome (PMS) or irritable bowel syndrome (IBS), which could delay further investigation.

"Unfortunately, most of the women in our group went to their GPs and particularly if they're under 50, they're told, you're fine, it's IBS, it's PMS, go away and come back," he told RTÉ.

Bowel cancer, also known as colorectal cancer, develops in the colon or rectum. It can often be treated successfully when detected at an early stage, but treatment becomes more difficult when the disease has spread to other parts of the body.

Screening is meant for people who do not have symptoms. Anyone experiencing possible warning signs should contact a healthcare professional rather than waiting until they become eligible for routine screening.

Is Salmonella Dangerous?

Salmonella is a group of bacteria that can cause a foodborne illness called salmonellosis. While it is most commonly linked to contaminated foods like poultry, eggs, or unpasteurized milk, it can occasionally turn up in dry goods and medicines if raw ingredients are exposed to the bacteria during harvesting or processing.

When someone ingests salmonella, the bacteria irritate the lining of the intestines. Symptoms usually show up anywhere from six hours to six days after exposure. Salmonella infection may cause:

• Diarrhea (which can sometimes be bloody)
• Fever
• Stomach cramps and abdominal pain
• Nausea and vomiting

Most healthy people recover within a week without any medical treatment. However, the infection can be much more severe and occasionally dangerous for young children, older adults, and individuals with compromised immune systems.

The bacteria can occasionally enter the bloodstream and cause more severe infections. The CDC has warned that the actual number of infections may be higher than reported because some people recover without seeking medical care or getting tested.
