Heart attacks and strokes are among the leading causes of death globally, with millions suffering from cardiovascular diseases (CVD) every year. There are more than seven million people in the UK alone, with about 100,000 patients experiencing heart attacks annually. However, a group of researchers at University College London (UCL) estimate that one 'polypill' taken daily day could eliminate a majority of these cases dramatically lowering death tolls.

The proposed polypill, a combination of a statin and three blood pressure-lowering drugs, has been under study for over two decades. Experts argue that introducing this pill universally for individuals aged 50 and above could be more effective than the current NHS Health Check, which assesses risk factors every five years for those aged between 40 and 74.

Studies have repeatedly proven the effectiveness of the polypill in preventing CVD. A groundbreaking 2019 study in The Lancet found that five years' use of the polypill cut the risk of heart attack and stroke by a third. In addition, previous modelling analyses have estimated that if given universally to people over 55, the polypill might be able to prevent 80% of heart attacks and strokes.

Today, the NHS Health Check follows a risk-based model in which patients are tested for CVD risk factors and treated with drugs accordingly. Yet, as per UCL's study, this system has serious flaws:

Low Uptake: Just 40% of those eligible for the NHS Health Check choose to have it, leaving a considerable number of at-risk patients undiagnosed and untreated.

Ineffective Prediction of Risk: The majority of heart attacks and strokes happen to people at average risk levels, thus making it challenging to identify the need for intervention effectively.

Limited Effectiveness: Even at maximum take-up, the NHS Health Check programme is predicted to have fewer health impacts compared to a polypill initiative applied to the whole population.

Simplicity and Affordability of the Polypill Strategy

One of the big benefits of the polypill is that it is so easy. In contrast to the existing screening-based model, the polypill scheme would not involve complicated medical tests or lengthy risk assessments. Instead, people reaching 50 would just have to fill out a few questions to determine possible side effects before they were prescribed.

Professor Aroon Hingorani of the UCL Institute of Cardiovascular Science, one of the strongest proponents of this scheme, says:

"Finally, the time is now to do much better on prevention. A population approach would prevent a lot more heart attacks and strokes than is done today with a strategy of trying to target a smaller group only."

Aside from the possible health implications, the polypill is also an economic solution. The drugs used are off-patent, thus cheap to produce and distribute. With the vast economic cost of managing CVD-related illnesses, a preventive model could result in substantial cost-saving for the NHS in the future.

The polypill has been proven to be effective by numerous international trials. In 2019, a randomised trial in rural Iran discovered that participants who took the polypill for five years had a 34% reduced risk of having a heart attack or stroke compared to non-participants.

Likewise, modelling research has indicated that even if only 8% of people aged over 50 took up the polypill regimen, it would still be more beneficial to their health than the NHS Health Check programme.

Is This a Case of Over-Medicalisation?

One of the main objections to the polypill strategy is the suggestion that it might result in the unnecessary medicalisation of a significant proportion of the population. But, it is argued, it should be considered as a preventative measure, not as mass medication.

Professor Sir Nicholas Wald of UCL's Institute of Health Informatics explains:

"Instead of being a 'medicalisation' of a significant proportion of the population, a polypill programme is a prevention measure to prevent an individual from becoming a patient."

He compares it with public health measures like water fluoridation or compulsory seatbelts—interventions that have been shown to have a significant impact in reducing public health danger at low individual cost.

With the evidence in favour of the polypill's effectiveness and viability overwhelming, experts are calling on the NHS to act now. It is their belief that substituting the NHS Health Check with a polypill-based prevention program could be the UK government's flagship policy under its pledge to put disease prevention ahead of cure.

As Professor Hingorani points out, "The status quo is not a justifiable option." With CVD still a major cause of death globally, taking a population-wide polypill approach could be a turning point for preventative medicine, potentially saving thousands of lives annually. The question now is whether the NHS will take up this call and establish a policy with the potential to transform the prevention of cardiovascular disease on a national level.

Flu cases are starting to fall, yet experts caution that the United States still faces risks. In the week ending January 10, fifteen more children died from the flu, bringing the total pediatric deaths this season to 32, as per NBC News.

Flu Season: Latest CDC Data

On Friday, the Centers for Disease Control and Prevention (CDC) reported an 18% drop in confirmed flu cases compared with the previous week. Visits to doctors for respiratory illnesses decreased by more than 5%, and hospitalization rates fell by nearly 55%. Influenza-related deaths, however, rose by 2%.

So far this flu season, the CDC estimates that 18 million people have been infected, including 230,000 hospitalizations and 9,300 deaths.

“It seems like there is some cautious good news that cases are declining,” said Jennifer Nuzzo, director of the Pandemic Center at Brown University School of Public Health. “But I’m going to put a giant asterisk on this because that does not mean the worst is behind us.”

Last year, flu cases dipped around this time before climbing again in early February.

Flu Season: State-by-State Variation

CDC data reflect a national trend, but not all states have necessarily reached their peak. “We are not going to all experience this at the same time,” said Beth Carlton, a public health professor at the University of Colorado, as per NBC News. “Nationwide, the trend is downward, but different states and communities may see spikes as the virus spreads.”

Flu often appears first in densely populated areas like New York City before moving to rural regions, but the virus can behave unpredictably.

Flu Season: Impact on Schools

Although flu cases may be falling overall, other winter illnesses such as norovirus, Covid, and strep throat are still causing school closures in states including Arkansas, Kansas, Kentucky, Tennessee, and West Virginia.

High flu activity continues in Idaho, New Mexico, New York, and parts of Appalachia, while Montana, South Dakota, Vermont, and Wyoming report lower case numbers.

“The number of people hospitalized for influenza around New Year’s was extremely high—the second highest in the past decade, with last year being the highest,” Carlton said.

Flu Season: A Difficult Flu Season

This year’s severe flu season is driven by a heavily mutated strain of influenza A called H3N2 subclade K. Its mutations make it less similar to the strain used in this year’s vaccine. Influenza-like illnesses, including RSV and Covid, are also unusually high, Nuzzo said.

“Typically these viruses peak at different times, but this year they are peaking together, making the season particularly harsh,” she noted.

While there were concerns that the vaccine would be less effective against subclade K, recent research shows the current flu shot still offers protection, particularly against hospitalization. The vaccine covers three strains: H1N1, H3N2, and one B strain.

Flu Season: Pediatric Risk

As per NBC News, last year marked the deadliest flu season for children since the CDC began tracking pediatric deaths, with 289 children dying—more than during the 2009 H1N1 pandemic.

“That double peak last season clearly had consequences,” Nuzzo said. “Any decline this season is welcome, but we can’t assume the worst is over.”

Among children eligible for the flu shot whose vaccination status was known, 90% of pediatric deaths occurred in unvaccinated kids.

Following recent CDC guidance, flu shots are no longer recommended for all children, a change from the previous advice that everyone six months and older should be vaccinated annually.

The Saudi Arabian Food and Drug Authority has cleared Anktiva, an IL-15–based immunotherapy created by billionaire physician-scientist Patrick Soon-Shiong and his biotech firm ImmunityBio, for the treatment of bladder cancer and lung cancer. This marks the first time the therapy has received national regulatory approval outside the United States.

The move signals an important global step for Anktiva, which currently holds a limited approval from the U.S. Food and Drug Administration. In the U.S., the drug is authorised only for patients with BCG-unresponsive, non–muscle-invasive bladder cancer (NMIBC) that includes carcinoma in situ. American regulators have so far resisted expanding its use to other bladder cancer subtypes. Saudi regulators, however, have adopted a broader stance, approving Anktiva for two cancer types under their domestic regulatory system.

What Is Anktiva?

Anktiva is an interleukin-15 receptor agonist designed to stimulate the body’s own immune defences. It works by activating and expanding natural killer (NK) cells and memory CD8⁺ T cells, which play a key role in immune surveillance. Unlike chemotherapy or gene-based treatments, Anktiva does not attack tumour cells directly. Instead, it boosts existing immune pathways to help the body recognise and destroy cancer cells.

ImmunityBio describes Anktiva as “the first FDA-approved immunotherapy that activates what’s called a natural killer cell to target and kill non-muscle-invasive bladder cancer cells.” In clinical practice, the drug is used alongside BCG (Bacillus Calmette-Guérin) in patients whose NMIBC has not responded to BCG alone. It is administered directly into the bladder through a catheter, followed by a structured maintenance schedule

Clinical Evidence Supporting FDA Approval in NMIBC

The FDA’s approval, issued on April 22, 2024, was based on results from a single-arm clinical study involving 77 patients with BCG-unresponsive stage 0 NMIBC. Participants received intravesical Anktiva combined with BCG, with maintenance therapy continuing for as long as 37 months.

The main efficacy results were as follows:

• Complete response rate: 62%

Durability:

• 58% of patients who responded remained disease-free for at least 12 months
• 40% stayed disease-free for 24 months or longer

For patients facing the prospect of radical cystectomy as the only curative option, these results were considered clinically significant. Still, the absence of a randomised control group has remained a point of contention among regulators and experts.

Regulatory Tension in the United States

Although the FDA approved Anktiva for NMIBC cases involving carcinoma in situ, it declined to extend the indication to patients with papillary-only disease. ImmunityBio pushed back against the decision, arguing that the same clinical data had already been deemed sufficient to support approval in a closely related patient group.

Rachel Sherman, MD, former principal deputy commissioner of the FDA, publicly criticised the agency’s stance, saying: “it is incomprehensible to me that the FDA refuses to file a supplemental BLA, stating the study is not sufficient to support a regulatory review, when it has already approved a product based on that very same study in essentially the same indication and population.”

The FDA has also expressed concerns about how the drug has been marketed. It issued a warning letter to ImmunityBio over promotional materials that cited survival benefits and cystectomy-avoidance rates not supported by robust evidence.

Saudi regulators, by contrast, have taken a more permissive view, approving Anktiva for both bladder and lung cancer and highlighting a willingness to act in areas of high unmet medical need.

With this decision, Saudi Arabia becomes the first country to approve Anktiva beyond NMIBC, potentially placing itself at the forefront of evaluating the therapy’s wider role across multiple cancer types.

Once a rare condition, non-alcoholic fatty liver disease (NAFLD) now affects one in three Indians, scientists say.

NAFLD, now called as metabolic dysfunction-associated steatotic liver disease (MASLD), is when excess fat builds up in the liver, unrelated to heavy alcohol use, due to obesity, Type 2 diabetes, high blood pressure and cholesterol.

It ranges from simple fat accumulation to inflammation and damage, which can progress to fibrosis, cirrhosis or liver cancer, The disease often has no symptoms and is managed with lifestyle changes such as diet and weight loss.

A JAMA study has now found that about 40 percent of the global population is now suffering from NAFLD, with abdominal obesity identified as its single biggest risk factor. Between 2010 and 2021, India recorded a 13.2 percent increase in age-standardized prevalence, ranking just behind China at 16.9 percent and Sudan at 13.3 percent.

What Did The Study Find?

Researchers found that nearly 70 percent of people with Type 2 diabetes and about 80 percent of those with obesity are affected by NAFLD. They also discovered that NAFLD prevalence is higher in men than in women, with rates of 15,731 per 100,000 population in men compared with 14,310 in women.

Additionally, the disease peaks earlier in men, between 45 and 49 years of age, while women show the highest prevalence between 50 and 54 years.

Why Is NAFLD on the rise?

Experts also note that working long hours at desks without any proper physical activity can lead to weight gain and fat accumulation in the liver.

According to the Union health ministry, the prevalence of the condition could be in the range of 9-53 percent. Multiple other health studies also suggest nearly 40 percent of urban Indians may have some form of fatty liver disease

Hepatologist Dr Cyriac Abby Philips, popularly known as LiverDoc on social media, noted on X that many patients do not realize that timely lifestyle changes can completely reverse the condition. “All it takes is being in charge of your body and health. No shortcuts—go slow and steady,” he wrote.

If left untreated, NAFLD can progress to Non-Alcoholic Steatohepatitis (NASH), where liver inflammation begins. Over time, this inflammation can lead to scarring of the liver, known as fibrosis. Advanced fibrosis results in cirrhosis, which severely affects liver function.

NAFLD can also increase the risk of chronic liver disease, liver failure and hepatocellular carcinoma. Many patients diagnosed with liver cancer have a history of untreated fatty liver.
