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.

The US Food and Drug Administration has recalled over three million eye drops in the country over safety concerns.

The 3,111,072 products were manufactured by California-based K C Pharmaceuticals and were sold under names such as “Dry Eye Relief Eye Drops,” “Sterile Eye Drops,” and “Artificial Tears Sterile Lubricant Eye Drops,” according to the FDA notice.

K C Pharmaceuticals made the voluntary recall of the eye drops in early March.

The eight types of eye drop products were sold at major retailers, including CVS, Walgreens, and Rite Aid. They have expiration dates ranging from April to October.

Eye Drops: Why Are These Recalled? What Did The US FDA Say

The FDA, in its Enforcement Reports, stated that the products recalled “lack of assurance of sterility.”

While so far, there are no reports of injuries associated with the eye drops, the FDA notice classified the action as a “Class II recall.”

Class II recalls apply to products that can cause “temporary or medically reversible” health problems.

As per the FDA, "the probability of a serious health issue is remote," over these products, and that is why the recall is categorized as a Class II, USA TODAY reported

"Patients and consumers can continue using the medicine unless otherwise directed by the recalling company or FDA," the regulator said in a statement to the publication.

The key to ensuring that your eyes are protected from environmental factors like the sun, dust, and dirt, especially for those who work outdoors or spend long hours on screen, is investing in good sunglasses with ultraviolet protection.

"For those who are using computers a lot, you need to blink your eyes constantly, take breaks in between, and drink a lot of water. Dehydration is also a contributing factor to dry eye," Dr Anita Sethi, who is Principal Director and HOD Ophthalmology, Max Multi Specialty Centre at Panchsheel Park.

She also recommends using zero-number protective glasses and computer glasses that can decrease strain and dry eye.

While advising people to stay away from natural remedies like turmeric or ginger put inside the eye, Dr Sethi urged people to consume more “foods rich in vitamin E, antioxidants” to maintain eye health.

“Colored vegetables and fruits, and even maintaining thyroid and vitamin D levels, because these also contribute to dry eye,” the ophthalmologist said.

Smokers turn to vaping thinking that it is cooler and more convenient. Little do they realise that this seemingly convenient act could cause long-term damage, most of it irreversible. Scientists now fear that vaping could be linked to not one, but two forms of cancer. E-cigarettes can trigger lung and mouth cancer, and this is a consequence of the DNA-damaging chemicals found in vapes. Researchers at the University of New South Wales in Sydney came to this conclusion after reviewing studies on mice that developed lung tumours after being exposed to aerosol. Reports also suggest that heavy smokers are more prone to mouth cancer.

Why are vaping pens linked to cancer?

Vapour from pens has a relatively better fragrance compared to conventional cigarettes, as these pens are flavoured. However, researchers say that these pens contain chemicals that can cause cancer, damage DNA, and lead to tissue inflammation. Researchers also say that e-cigarettes contain nicotine, which is likely to trigger lung and mouth cancer. However, the extent of this effect in humans is still unknown.

Lead researchers of the study said that they would only be able to determine the precise risk once long-term studies are available. Contrary to popular belief, while many believe that vaping is far safer than smoking, the study’s findings act as a warning for all those who use a vape but have not smoked a cigarette in their life. Experts at the University of Sydney noted that vaping is a safer alternative to smoking for smokers. However, the research has drawn criticism for being “problematic” and “misleading”.

Experts at University College London said that no one would argue that e-cigarettes are completely risk-free. Rather, they said, vapes should be used as a harm-reduction tool to help smokers quit the habit, thereby reducing their risk of chronic and acute health problems, such as heart disease. The review, however, does not give a free pass to use e-cigarettes. It issues a warning against the use of vapes, citing risks of lung and oral cancer. At a time when vape use has increased suddenly, overtaking the popularity of smoking, research is necessary to discourage people, especially youngsters, from adopting the habit in the first place.

Cancer, a rare occurrence? Unfortunately, not anymore. According to recent findings from an analysis published in The Lancet, cancer is one of the top 10 causes of death among Indian children. This is an alarming statistic, signalling an under-recognised public health problem. Data in the Global Burden of Disease Study 2023 noted that even as infectious diseases decline, noncommunicable diseases like cancer are emerging as a serious threat to child survival and well-being. In India, this epidemiological shift is particularly concerning in the context of childhood cancers. Despite being rare, they are highly treatable when detected in the early stages—yet most cases are diagnosed late.

As per the Indian Council of Medical Research’s National Centre for Disease Informatics and Research (ICMR-NCDIR), childhood cancers accounted for 3–5 per cent of cancer cases reported in India in 2022. The country sees an estimated 50,000 to 60,000 cases every year among children aged 0–14 years. This makes it one of the highest burdens globally. In 2023, 377,000 cases of childhood cancer were reported globally, along with 144,000 deaths, according to The Lancet research paper.

Hidden cancer burden in India

When it comes to childhood cancers in India, leukaemia, or blood cancers, are the most common, followed by lymphomas and tumours of the central nervous system. Collectively, these categories comprise most cases of childhood cancers in the country. The statistics vary across regions, with Delhi reporting the highest number of cases due to better diagnostic facilities. However, experts believe that the actual burden is likely to be much higher. Incomplete cancer registration and limited access to proper diagnostic facilities in underserved and rural areas are to blame for delayed diagnosis.

Why is childhood cancer detected late in India?

Experts say that cancer deaths in India can largely be attributed to delayed diagnosis. Early symptoms of cancer in children include fatigue, fever, unexplained weight loss, and swelling in certain body parts. These symptoms are often overlooked, leading to delays at multiple levels. According to the ICMR 2022 factsheet, a significant proportion of children reach hospitals only at advanced stages of the disease. By then, treatment becomes more complex, more expensive, and less likely to succeed.

Access to cancer care for children

Access to cancer care for children is uneven in India. Paediatric oncology services are largely limited to hospitals in tier-one cities, forcing families from rural areas and smaller towns to travel in order to access proper treatment. This imbalance results in delayed care, especially for economically vulnerable families. Financial limitations are another barrier in the process—even if treatment costs are subsidised, expenses such as travel, accommodation, and loss of income can be overwhelming.

Irregular survival patterns

Globally, survival rates for childhood cancers exceed 80 per cent in high-income countries. In India, outcomes are uneven. The ICMR 2022 factsheet noted that survival depends on the stage of diagnosis, type of cancer, and where the child is treated. Hospitals in India are reporting improving survival rates for certain forms of cancer, such as acute lymphoblastic leukaemia. The ICMR factsheet also highlights the need for a dedicated approach to paediatric cancer care, including better infrastructure, trained doctors, and stronger referral systems.
