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.

Nathan Crawford from the UK was just 9-years-old when his testicular tissue was frozen, before undergoing chemotherapy for his brain tumor.

About 16 years later, the cryopreserved immature testicular tissue was reintroduced into his body, which triggered sperm cell production and restored his fertility, according to researchers from the Vrije Universiteit Brussel.

“This is an important step in further scientific research to preserve the fertility of children with cancer or other blood diseases for the future. While the procedure is specifically designed to restore fertility, we cannot at this time guarantee that it will be successful or that patients can go on to have children. This treatment offers lots of perspectives for these young adults. They now have options that they did not have until recently,” said Dr Veerle Vloeberghs, part of the novel trial and staff member at Brussels IVF.

What Had Happened To Nathan

Nathan, now 27-years-old, had a type of tumor called a glioma, which develops from the glial cells that support the nerve cells of the brain, The Guardian reported. The tumor was so close to vital brain tissue that surgeons were unable to remove it without causing serious damage to important brain functions.

He underwent radiotherapy and chemotherapy to shrink his tumor, before which surgeons at the John Radcliffe hospital in Oxford in a keyhole surgery removed and froze a wedge of testicular tissue, with the aim that it is one day re-implanted into Nathan.

How Is The Testicular Tissue Preserved?

While Chemotherapy and radiation therapy are lifesaving they can destroy testicular stem cells, the precursors of sperm cells in boys who undergo radical treatments before starting puberty. As it can affect their fertility, preventively removing and freezing testicular tissue is an option pioneered by UZ Brussel.

In 2002, UZ Brussel became the first hospital worldwide to initiate a clinical fertility preservation program for young boys suffering from cancer or diseases of the blood, bone marrow or lymph nodes.

Since then, the hospital has frozen testicular tissue fragments of 141 boys.

The tissue is preserved in liquid nitrogen at -196°C.

Prepubescent boys do not yet produce sperm cells. The removed tissue contains stem cells that would normally produce sperm after starting puberty.

"While the procedure is specifically designed to restore fertility, we cannot at this time guarantee that it will be successful or that patients can go on to have children,” Dr Vloeberghs said.

How Was The Testicular tissue Implanted

The Guardian reported that in 2025, four tissue fragments were grafted back into the remaining testicle and four under the skin of the scrotum.

After a year inside the body, the grafts were removed and analysed in the laboratory. The results are published in a preprint paper, which is yet to be peer reviewed.

Two of the grafts from inside the testicle had produced mature sperm, which was collected and frozen.

Because the tissue fragments are not directly connected to the sperm duct, the researchers do not expect sperm cells to naturally find their way into the semen.

“This is a huge finding,” Prof Ellen Goossens, of the Vrije Universiteit Brussel, who led the trial was quoted as saying. “Many more people will have hope that they can have biological children. It’s great to see for the patients for whom we already have tissue banked.”

A new research paper published in the PNAS Journal triggered concerns over the potential risk of influenza D spilling over into humans.

Although primarily found in livestock such as cattle and swine, this virus has been increasingly studied due to evidence of exposure among agricultural workers.

A key concern raised was that the influenza D virus triggers a relatively weak early immune response in human respiratory cells.

However, to understand whether it is just a hype or a real concern, HealthandMe spoke to Dr. Rajeev Jayadevan, Ex-President of IMA Cochin and Convener of the Research Cell, Kerala.

“So far, this virus has not been a major cause of respiratory disease in man, unlike other types of Influenza viruses like H1N1 and H3N2 of the Influenza A family. It is true that studies have demonstrated antibodies against this virus among cattle farmers, which is consistent with its ability to infect species other than cattle,” Dr. Jayadevan said.

He noted that the virus may not be an “imminent threat” to humankind as feared.

“So far, the signals are that this virus remains primarily a cattle pathogen, which doesn’t pose an imminent threat to man, unlike other types of influenza viruses”.

What is the Influenza D Virus?

Influenza D is one of four types of influenza viruses and belongs to the Orthomyxoviridae family. Unlike the more familiar influenza A and B viruses that cause seasonal flu in humans, influenza D has primarily been detected in animals, particularly cattle and pigs.

According to the US CDC, the virus was first identified in 2011. It has since been found across multiple species, including livestock and wildlife, including camels, deer, giraffes, kangaroos, llamas, wallabies, and wildebeests.

It is not currently known to cause illness in humans, but has had a spill over in different animal species — more recently in poultry.

CDC’s January 2026 report stated that “influenza D has shown to have considerable potential for causing future human epidemics, but diagnostics and surveillance for the viruses are lacking”.

What Did The PNAS Study find?

Researchers investigated multiple influenza D virus isolates collected from livestock between 2011 and 2020 to assess their ability to infect human airway systems.

The paper demonstrated that the virus is capable of infecting human respiratory cells and was also adept at switching off the interferon-based ‘alarm systems’ of the cell.

This means that the virus may spread silently and efficiently, but without causing significant symptoms, Dr. Jayadevan said.

Importantly, the findings suggest that only small genetic changes might be needed for influenza D virus to achieve more sustained transmission in humans, although this has not yet been observed.

H5N1 Bird Flu: A More Deadly Threat

Dr. Jayadevan told HealthandMe that a bigger concern for humans besides the commonly circulating human Influenza A and B viruses is the avian influenza (bird flu) virus H5N1.

H5N1 spreads among birds and carries a very high death rate whenever it infects humans.

“Fortunately, this bird flu virus isn’t able to easily spread from person to person, but ongoing mutations could potentially change that,” the expert said.

US President Donald Trump’s visit to a dentist in Florida over the weekend has reignited discussions about his health.

While past presidents have opted for the White House's on-site clinic, Trump went for a local dentist instead, a choice he made previously in January.

Trump's Dentist Visit Triggers Concern

Concern for the health of the President, set to turn 80 next month, was further fueled by a social media post by Nancy Mace, representative for South Carolina, where she wrote, “Pray for President Trump.”

Her sudden post came after the news that Trump had left his Jupiter golf club in Florida for a dentist appointment.

The White House, in a press pool reported: "President Trump is going to a scheduled dental appointment at his local dentist in Florida", The NewsWeek reported.

Republican strategist Cheri Jacobus also wondered about the timing of the President's appointment and what "caused him to suddenly leave his golf course?" Jacobus also questioned the White House for hiding Trump's health status.

However, there has been no statement from Trump’s office, family, or verified government channels confirming any medical emergency or surgical procedure as of now.

Trump's Health Issues

It is not the first time that Trump has been the subject of numerous health-related scrutiny — ranging from his mental state to visible bruising around his hands.

While there remains no official medical update on the discoloration in Trump's hand, Dr. Amit Prakash Singh, Consultant - Internal Medicine at the CK Birla Hospital, Delhi, told HealthandMe that there are possible underlying causes that can result in hand discoloration. He noted that the condition may be due to:

• Bruising (bleeding under the skin)
• Low oxygen or poor circulation
• Swelling (fluid buildup in tissues)
• Infection or inflammation

Media reports also expressed concern over Trump’s swollen ankles, which were photographed again during his weekend trip to Florida.

On Saturday, Trump was photographed with his son, Donald Trump Jr. His swollen ankles visible in the photos are likely the result of chronic venous insufficiency (CVI), which he was diagnosed with last July.

"CVI damages those valves, causing blood to pool in your legs. This increases pressure in your leg veins and causes symptoms like swelling and ulcers," according to the Cleveland Clinic.

In January, Trump told the Wall Street Journal that he'd tried using compression socks to help treat the issue but stopped because he "didn't like them."

Trump has also made some unusual medical choices in the past. Most notable is his use of aspirin. Trump takes 325 milligrams of aspirin every day, according to the Daily Beast. That's four times the doctor-recommended dosage.

Trumps' Dipping Image Among Americans

Meanwhile, nearly 60 per cent of Americans are questioning whether or not Trump is healthy enough to serve in the Oval Office, according to a Washington Post-ABC News-Ipsos poll.

In addition to dissatisfaction over Trump’s leadership on the Iran war, economy, and inflation, a growing share of Americans are also questioning the President’s mental acuity for the position.

Nearly 6 in 10 say he does not have the mental sharpness, while 55 percent say he is not in good enough physical health to serve effectively.
