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.

A 2026 target trial emulation has found that glucagon-like peptide, also known as GLP-1, which is used by type-2 diabetes patients, can raise the risk of suffering from erectile dysfunction. According to a report published in the European Medical Journal, the impact of GLP-1s on sexual health outcomes in diabetic men has been inconsistent and limited. Erectile dysfunction, however, has been a prominent complication affecting 50 per cent of men with type-2 diabetes over their lifetime.

The effect of GLP-1 on men with type-2 diabetes

For this, researchers analysed the electronic health records of men aged 18 years and above with type-2 diabetes in the US from January 2019 to September 2024. Participants were started on treatment with either dipeptidyl peptidase-4 inhibitors (DPP4i) or GLP-1, with 5,524 and 4,910 individuals, respectively. Men with a history of erectile dysfunction diagnosis or end-stage renal disease were not part of the study population. The mean age of these men was 63 years, and the average BMI was 32.8—55 per cent of participants were White, and 23 per cent were Black. GLP-1 users were younger and had a higher prevalence of obesity compared to DPP4i users.

Higher rate of erectile dysfunction

Experts involved in the study found that the incidence of erectile dysfunction in the GLP-1 group was about 35 cases per 1,000 person-years. In the case of DPP4i users, the number dropped to 28 per 1,000 person-years. Hence, people in the GLP-1 cohort had a 26 per cent higher risk of developing erectile dysfunction over a three-year follow-up period. Results were consistent across subgroups; however, they lacked statistical significance after adjustment for negative outcomes.

Can GLP-1 cause erectile dysfunction?

Researchers noted that the findings of the target trial emulation suggest that sexual health outcomes must be considered in diabetic men, especially those dealing with type-2 diabetes and undergoing treatment with GLP-1 drugs. These findings also highlight the need for randomised trials with standardised erectile dysfunction assessments to further investigate biological pathways.

What complications does type-2 diabetes cause in men?

Type-2 diabetes can cause the following complications in men:

1. Heart disease
2. Stroke
3. Erectile dysfunction
4. Kidney disease
5. Retrograde ejaculation
6. Lower testosterone levels
7. Urinary retention or frequent urination
8. Vision loss—diabetic retinopathy

New global guidelines have just been released for breast cancer screening, and they involve the introduction of artificial intelligence in the process. Breast cancer is one of the most commonly diagnosed forms of tumour in women globally. In India, it is the most common form of cancer detected in women living in metro cities. According to the National Comprehensive Cancer Network (NCCN), a non-profit alliance of 33 cancer treatment centres in the US, women aged 35 years and above should be eligible for AI-powered mammogram risk assessment rather than at a later stage.

Why is timely prediction of cancer risk important?

The NCCN aims to boost the diagnosis rates of breast cancer by paving the way for accurate predictions of risks. This will, over time, help achieve timely screening. As per experts, this change in global breast cancer screening guidelines, especially the integration of AI in the process, marks a paradigm shift—from a detection-first to a prediction-first approach. Historically, mammograms were used after the age of 40 for the detection of existing cancers. The modern guidelines, however, recommend that women get screened from the age of 35 onwards, with AI algorithms used to predict future risks.

What this means for India

Experts say that this shift is important for India. In India, breast cancer is the most prevalent form of tumour among women, and delayed diagnosis is one of the reasons responsible for the current mortality rate. Breast cancer is also often diagnosed late because of the unavailability and limited accessibility of screening facilities. Introducing AI in this process can help bridge the gap in several ways.

Doctors say that the introduction of AI in the breast cancer screening process will help facilitate the identification of high-risk patients, regardless of their family history or the presence of genetic markers. This is important because most cases of breast cancer do not arise from these factors. This helps provide screening in a way that does not require universal testing.

Traditional screening methods for breast cancer

Traditionally, cancer screening largely depends on family history and age. AI, however, can now analyse large volumes of imaging data, clinical history, breast density, and genetic factors for a more personalised approach and targeted diagnostic methods. The adoption of AI-driven risk assessment can help improve patient outcomes, as per doctors.

Use of AI in breast cancer detection

Women at high risk of breast cancer can make detection easier for themselves by making use of advanced modalities such as MRI. An MIT-developed AI-based breast cancer risk model can detect tumours up to five years in advance using mammographic data alone. This AI-based risk assessment technique has also been recommended by global experts and is published in The Lancet. The study found consistent favourable outcomes.

Rising global temperatures are driving heatwave conditions in India, said the Indian government, while releasing an advisory to warn people about the increased health risks.

Taking to the social media platform X, the Ministry of Health and Family Welfare urged the public to take precautions during extreme heat.

"Heat waves are increasing due to rising global temperatures," said the Ministry in the advisory.

It shared safety measures and an informative poster explaining the impact of rising temperatures and steps to manage heat stroke.

The poster highlighted that a rise of 1 degree Celsius in global temperatures can lead to longer durations of heatwaves.

Further, it stated that insufficient hydration during heatwaves reduces the body's natural ability to cool itself, which can result in heat stroke.

The poster also detailed preventive measures to avoid heat stroke. It also advised people to avoid heavy work during mid-noon hours, drink plenty of water, avoid consuming heavily caffeinated or sugary drinks as they may cause dehydration, wear light-colored clothes, and take frequent breaks while working outdoors.

Which States Are At Risk?

The India Meteorological Department (IMD) has warned of heatwave conditions in several parts of the country.

Regions likely to face extreme heatwave conditions until April 20 include Telangana and Rayalaseema, Madhya Maharashtra and Marathwada, North Interior Karnataka, Madhya Pradesh, Chhattisgarh, Vidarbha, Odisha, Jharkhand, and West Rajasthan.

In addition, hot and humid weather conditions are expected in coastal regions such as Kerala, Tamil Nadu, Gujarat, and Coastal Andhra Pradesh.

Meanwhile, the national capital saw its hottest day of the year on Wednesday, as temperatures climbed sharply, signaling the onset of harsher summer conditions. According to IMD, the maximum temperature at Safdarjung, the city’s base station, touched 39.2 degrees Celsius, about 3 degrees above normal. This surpassed Tuesday’s 38.2 degrees Celsius, marking a noticeable upward trend.

While the mercury is expected to inch closer to 42 degrees Celsius by Friday, the weather office has ruled out heatwave conditions for at least the next week.

“A gradual rise is expected in maximum temperatures by 2-3 degrees during the next three days and fall by 1-2 degrees thereafter. The maximum temperatures are likely to be above normal to appreciably above normal during the next seven days," Times Of India quoted a Met official as saying.

As per the weather department, despite a slight chance of light rain in parts of Haryana and NCR on April 17 and 18, there is no relief expected for Delhi.

Forecasts suggest daytime temperatures will hover between 39 degrees Celsius and 41 degrees Celsius on Thursday, rising further to 40-42 degrees Celsius from Friday through Sunday.

The IMD has cautioned that such above-normal temperatures could pose moderate health risks, especially for infants, elderly individuals, and those with chronic illnesses.

Hydration Is key, Say Doctors

Dr. Anil Gomber, Director and Senior Consultant – Internal Medicine & Diabetologist, Yatharth Hospital, told HealthandMe: “It is crucial to take preventive measures to avoid heat-related illnesses".

Prolonged exposure to high temperatures can lead to dehydration, heat exhaustion, and heatstroke, which can be fatal if untreated.

Heat also places extra strain on the heart and lungs, increasing the risk of heart attacks and respiratory distress.

Heatwaves can increase the risk of deaths among the elderly and those with underlying medical conditions. It can also affect healthy and young people. Exposure to intense heat can cause headaches, dizziness, cramps, and fainting, particularly for those working outdoors or engaging in strenuous activity.

"Elderly people, kids, and those with chronic conditions like heart disease or diabetes face higher risks, so check on neighbors and family daily," Dr. Meenakshi Jain Principal Director & HOD Internal Medicine, Max Super Speciality Hospital, told HealthandMe.

She urged people to "watch for warning signs like dizziness, rapid heartbeat, nausea, or confusion, and move to a cool area immediately if they appear—seek medical help for severe symptoms. Keep homes cooler by closing curtains during the day and opening windows at night".
