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.

Sunlight brings energy, positivity and vitamin D, but not for two-year-old Mollie Murray from Scotland, who has a rare genetic disorder that makes her “allergic” to the sun.

She is reportedly the only child in the UK known to be living with xeroderma pigmentosum (XP), a condition that makes the skin extremely sensitive to ultraviolet (UV) light.

The incurable disorder puts Mollie at risk of severe sun damage year-round. She can only safely go outside in protective full-length clothing or after dark.

“She burns all year round and has burnt in November before,” her mother, Kirsty Campbell, 35, a charge nurse, was quoted as saying to The Sun.

“Everyday life is difficult as she needs full protective outerwear for going outside and sun cream every two hours under her clothes.”

UV-Resistant Film Lets Mollie Play In Daylight

Now, thanks to the charity The Archie Foundation, UV-resistant film installed at Mollie’s home last month means she can play indoors during the day without the curtains being closed.

“It means she can do simple things like look outside for the postman or draw in daylight. My ex-partner was having to take playpark equipment into his house as it wasn’t safe outside. She’s so happy running around like a normal child,” her father, Ryan Murray, 34, said.

How Was Mollie Diagnosed?

Mollie was in and out of hospital from infancy with symptoms including seizures and severe reflux.

She first experienced severe sunburn on an overcast day in May 2025. It happened again two months later, eventually leading to her diagnosis with XPF.

Doctors have advised that Mollie is 10,000 times more likely to develop skin cancer than other children. Campbell also uses a UV monitor to check readings in every room and ensure it is safe for Mollie.

The Sun said that her family has been told she may develop neurological impairment and mobility problems in her 40s and 50s, but that she should have a relatively normal childhood.

What Is Xeroderma Pigmentosum?

The National Institutes of Health (NIH) describes XP as a rare autosomal recessive genetic disorder marked by extreme sensitivity to UV radiation, changes in skin pigmentation, skin cancer and, in some cases, neurological problems.

The condition usually appears in early childhood and significantly increases the risk of skin cancer.

XP affects roughly one in a million people in the US and Europe, although it is more common in some other parts of the world.

XP itself is not cancer, but it can increase the risk of skin cancer by thousands of times. Other cancers may also be more common in people with the condition.

XP is caused by mutations in specific genes that affect the body’s ability to repair UV-induced DNA damage. It is inherited from parents.

Symptoms Of Xeroderma Pigmentosum

• Skin: Severe sunburn even after brief UV exposure, dry or thin skin, early freckles, changes in skin colour, fragile skin and precancerous growths such as actinic keratoses.
• Eyes: Dryness, irritation, light sensitivity and corneal damage, which can potentially lead to vision loss.
• Neurological: Some people may develop difficulty swallowing, loss of reflexes, problems controlling muscles, cognitive decline and hearing loss.

How Is XP Diagnosed And Treated?

XP can be diagnosed through specialised laboratory tests, including studies of cellular sensitivity to UV radiation, chromosomal breakage, complementation studies and gene sequencing.

But there is currently no cure for XP. Management focuses on avoiding UV exposure, monitoring for complications and treating symptoms.

How Mollie’s Family Is Protecting Her

For Mollie’s family, the priority is to protect her while allowing her to experience as much normality as possible. The UV-resistant film has made a small but significant difference, allowing her to look outside, draw in daylight and play indoors without keeping the curtains closed.

Mollie’s family hopes to give her the highest possible quality of life while keeping her safe.

An 8-year-old Louisiana girl has died after contracting Naegleria fowleri, the rare “brain-eating amoeba” infection believed to have been acquired while swimming in Lake Claiborne.

The girl, identified by her family as Lillian Smart of Ruston, died on August 22, just one day after her eighth birthday. She had been hospitalised since August 15 after developing the infection.

The Louisiana Department of Health confirmed the case on August 19 but has not publicly identified the child. The tragedy has renewed attention on an extremely rare and fatal infection.

Why Naegleria Fowleri Can Become Deadly So Quickly?

The amoeba then can travel along the olfactory nerves through the nasal cavity and reach the brain, where it causes primary amebic meningoencephalitis (PAM). Also, swallowing contaminated water does not cause PAM, and the infection does not spread from person to person. PAM causes severe inflammation and destruction of brain tissue.

The illness can initially resemble other infections, with symptoms including headache, fever, nausea and vomiting. As the disease progresses, patients may develop advanced symptoms like stiff neck, confusion, hallucinations, seizures, and eventually coma.

One of the biggest challenges is the speed at which the infection progresses. According to recent CDC data cited in coverage of the Louisiana case, 173 Naegleria fowleri infections were documented in the US between 1937 and 2025, with only four known survivors. That puts the fatality rate at roughly 97%.

Early Symptoms Mimic Other Illnesses

The initial symptoms of PAM can look like bacterial or viral meningitis, which can make the infection difficult to recognise immediately. An individual may initially experience fever, headache, nausea and vomiting before developing neurological symptoms.

By the time the amoeba is identified, significant brain inflammation may already have occurred. Diagnosis can involve testing cerebrospinal fluid or brain tissue for the organism. So, rare early symptoms and rapid progression makes early diagnosis of this infection particularly difficult.

There Is No Cure For Naegleria Fowleri

There is no single drug that reliably cures PAM. Because so few cases occur, there have been no large clinical trials establishing a standard treatment regimen.

Doctors have used combinations of antimicrobial and antifungal medicines in survivors and severe cases, with treatment often including drugs such as amphotericin B and miltefosine, alongside intensive supportive care.

The CDC notes that successful treatment has involved combinations of several medicines, but outcomes remain poor.

Simple Precautions Can Reduce The Risk

The CDC recommends avoiding activities in warm freshwater, particularly when water temperatures are high. For people who do enter such water, precautions include:

• Using a nose clip or keeping the nose above water
• Avoiding jumping or diving into warm freshwater
• Avoiding stirring up sediment in shallow, warm areas
• Avoiding putting the head underwater in potentially contaminated water

Actor Michael Wright, best known for playing Eddie King Jr. in the 1991 musical drama The Five Heartbeats, has died at the age of 70 in Los Angeles. According to his kin, Wright died on August 19. His death was linked to heart failure along with complications from Marchiafava-Bignami disease, a rare degenerative neurological condition.

His wife, Susan Wright, announced his death in a social media post, “It is with profound sadness and an unimaginable heaviness in my heart that I share the passing of my beloved husband, Michael Wright,” Susan wrote, remembering the actor as a “loved one, a friend, and an extraordinary artist whose work touched generations.”

According to a statement from Wright’s family, he suffered heart failure together with complications from Marchiafava-Bignami disease. MBD is a rare neurological disorder that primarily affects the corpus callosum, the thick bundle of nerve fibres connecting the brain’s two hemispheres.

It is most commonly associated with severe alcohol use disorder and nutritional deficiencies, although it can occur in other circumstances.

The condition can cause symptoms including confusion, impaired consciousness, problems with movement, seizures and changes in cognitive function. As MBD is extremely rare, doctors may have difficulty recognising it, particularly in its early stages.

Wright's cause of death was heart failure due to the neurological disease. Heart failure occurs when the heart cannot pump enough blood to meet the body's needs. Depending on the type and severity, this can lead to breathlessness, fatigue, swelling in the legs, rapid heartbeat and reduced ability to perform everyday activities.

Heart failure can develop because of conditions including coronary artery disease, high blood pressure, heart attacks, cardiomyopathy and abnormal heart rhythms. In Wright's case, his family said heart failure occurred alongside complications from MBD. They did not publicly provide further details about what caused his heart failure.

Wright Had A Career Spanning Nearly Five Decades

His most memorable performance came in The Five Heartbeats, where he played Eddie King Jr., the troubled lead singer of a fictional R&B group. He also appeared in television series including V and HBO's Oz.

Wright's career continued into later years, with his final credited appearances including the television series Black Lightning and the 2025 film Dope King.

Susan Wright said the family has requested privacy while grieving and said further details about his life and legacy would be shared later. She said she was experiencing “profound sadness and an unimaginable heaviness” following his death.

She remembered her husband not only for his acting career but also as a loved one, friend and artist whose work had reached generations of audiences. Wright is survived by his wife, daughter, stepchildren and other family members.
