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.

Pennsylvania has reported its fourth measles-associated death after an 18-year-old from Mifflin County died from a rare and severe neurological complication of the infection.

The Pennsylvania Department of Health confirmed two additional measles-associated deaths on September 15, including the 18-year-old and an unvaccinated person from Jefferson County. The state has now recorded four measles-associated deaths in 2026 as its outbreak continues to expand.

The latest casualty highlights acute disseminated encephalomyelitis (ADEM), one of the most serious complications of measles can cause. In this condition, the inflammation damages the brain and spinal cord.

How Can Measles Affect The Brain?

According to Mifflin County Coroner Andrea Alcalde, a review of medical records and available investigative information determined that the 18-year-old died from acute disseminated encephalomyelitis, which she described as a rare and severe neurological complication of measles.

Ruled as a natural death, the individual was unvaccinated, according to Pennsylvania health officials. ADEM entails inflammation of the brain and spinal cord. It can cause neurological symptoms and in extreme cases, can become life-threatening.

Measles itself is highly contagious and can cause complications that could impact multiple organs. Pennsylvania health officials say serious complications can include pneumonia and brain swelling, while around 20% of people identified with measles in the state have required hospitalisation during the current outbreak.

Pennsylvania Has Now Recorded 4 Deaths

The latest deaths come as Pennsylvania continues to experience its worst measles outbreak in more than three decades. The state has recorded 693 confirmed measles cases across 38 counties in 2026, according to the Pennsylvania Department of Health.

The four deaths include two infants from Lancaster County reported in August, a 40-year-old woman from Jefferson County who died from measles complications, and the 18-year-old from Mifflin County. The outbreak has been concentrated in Lancaster and Mifflin counties, although infections have now been reported across more than half of Pennsylvania's counties.

The state health department said all four individuals were unvaccinated. The two infants were too young to receive routine measles vaccination.

Pennsylvania Secretary of Health Dr Debra Bogen said, “My thoughts are with the two families who lost loved ones to this highly-contagious virus, as Pennsylvania faces the worst measles outbreak in more than three decades.”

She added, “We remain committed to working with our partners across Pennsylvania to stem this outbreak and prevent more deaths. That means ensuring people have the facts about measles and access to the MMR vaccine – which kept measles outbreaks at bay for decades.”

Worst Measles Outbreak In History

Measles is among the world's most contagious infectious diseases. It spreads through respiratory droplets and airborne particles when an infected person coughs, sneezes or breathes.

The Pennsylvania Department of Health says measles-associated deaths, while rare, occur in around one to three people per 1,000 cases.

The department also says two doses of the measles, mumps and rubella (MMR) vaccine provide 97% lifetime protection. The state has identified four breakthrough infections among appropriately vaccinated people during the current outbreak.

Ireland experienced its largest reported community-acquired MRSA outbreak in 2025, with researchers linking 48 skin and soft-tissue infections to bouncy castles at an outdoor gathering, according to a report published in Eurosurveillance.

The outbreak sickened children and teenagers aged 5 to 16, with 15 requiring hospital care and four being admitted. None required intensive care, and there were no deaths.

Health officials traced the cluster to an outdoor social gathering in eastern Ireland in fall 2025, where children and teens played on three inflatable bouncy castles, many for several hours.

Nearly everyone who fell ill had attended the event, and all 47 cases who were at the gathering had played on the inflatables, researchers said.

The infections were caused by methicillin-resistant Staphylococcus aureus (MRSA), a drug-resistant form of staph bacteria that can cause painful skin infections and, in serious cases, spread deeper into the body.

The strain involved in the outbreak also carried Panton-Valentine leukocidin (PVL), a toxin associated with skin and soft-tissue infections. Researchers said the strain is rare in Ireland.

The illnesses developed rapidly. Thirty-four of the 48 cases developed symptoms within two days of the gathering, with some children becoming sick within 24 hours.

Among the 27 cases where doctors recorded the location of infection, the legs were most commonly affected, particularly the thighs.

Some children also developed fever, nausea or vomiting.

Thirty-three children were treated by a general practitioner, while 15 went to a hospital emergency department or day ward. Four were admitted, with a median hospital stay of four days.

How The Outbreak May Have Spread

Researchers said the gathering took place on a warm, humid and intermittently rainy day. Parents recalled that children playing outside were noticeably wet.

About 120 people were believed to have attended the gathering, roughly half of them children and teenagers.

What Is MRSA?

MRSA is a type of Staphylococcus aureus (staph), a common bacterium that can cause infections. It is resistant to several commonly used antibiotics.

According to the US CDC, anyone can develop or carry an MRSA infection. The risk is higher with factors such as recent hospitalization or nursing home stays, skin-to-skin contact including during contact sports, and exposure to crowded or unhygienic settings.

Signs And Symptoms

Symptoms of a S. aureus infection, including MRSA, depend on the part of the body affected.

MRSA skin infections often develop through broken skin, such as cuts or scrapes. They may appear as a bump or infected area that is:

• Red
• Swollen
• Painful
• Warm to the touch
• Filled with pus or other drainage
• Accompanied by fever.

Health officials in the Democratic Republic of the Congo (DRC) have stated that the Ebola outbreak has reached its peak, with the number of new cases slowing for the first time since May.

However, the UN has warned that the epidemic remains “massive” and is still growing in some areas, while the World Health Organization (WHO) said it is too early to confidently conclude that the outbreak has passed its peak.

The outbreak, caused by the rare Bundibugyo virus, was declared by the WHO on May 15. It is the DRC’s 17th Ebola outbreak since the virus was first identified in 1976.

It is also the second-deadliest Ebola outbreak on record, behind the West African outbreak that lasted from 2014 to 2016.

While clinical trials are ongoing for vaccines and treatments against Bundibugyo virus, the DRC received more than 70,000 doses of the Ervebo vaccine last month. Ervebo is approved for protection against the more common Zaire Ebola virus.

According to the latest data from the Congolese health ministry, more than 7,200 confirmed cases and over 3,475 deaths had been reported as of September 14.

Congolese Health Minister Samuel Roger Kamba said transmission of the Bundibugyo virus had declined, with daily cases falling from about 120 at the peak in mid-August to around 80.

“We are fighting a very dangerous virus that is killing many of our people. Today, we can say that the outbreak is under control,” he said.

“At one point, we were recording about 120 cases per day; today, we’re seeing about 80 per day. So the number of new cases is decreasing every day.”

Kamba said 10 of the 62 affected health zones had reported no new cases for more than 22 days. Six health zones had gone more than 42 days without a new case, while four had gone more than 21 days without one.

He said the figures were “encouraging” but stressed that people must remain fully mobilized and not lower their guard.

Last week, Sud-Ubangi province, which borders Congo-Brazzaville and the Central African Republic, became the sixth province to report Ebola cases.

While welcoming the progress, Iracan Gratien de Saint-Nicolas, an MP for Bunia, warned against “triumphalism” and called for greater transparency over the outbreak data, The Guardian reported.

“Claims that an epidemic is under control must be supported by objective indicators. If the indicators show that the epidemic is indeed under control, let’s make them public. Transparency in the data will strengthen public confidence,” he said.

He also called for lessons to be learned from failures in epidemiological surveillance that contributed to the rapid spread of the disease.

What Is The UN Saying?

UN officials acknowledged that response efforts were showing results but warned that the epidemic remained “massive” and could take months to bring under control.

“It remains a deadly and a massive epidemic. There are some areas of progress, but nonetheless, in other areas, we continue to see growth in cases,” Julien Harneis, the UN special Ebola coordinator, told a Geneva press briefing.

Asked about reports that the epidemic had reached a turning point, WHO's Olivier le Polain said: “It's too early to confidently say we have passed a peak”, Reuters reported.
