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.

New York City just rolled out new measures in a response to prevent Legionnaires’ disease after a major outbreak on the Upper East Side left 11 people dead and 94 infected.

The new measures, announced by Mayor Zohran Mamdani and the NYC Health Department on September 1, aim to improve monitoring of cooling towers, speed up testing and enforcement, and make information about possible risky systems easier for the public to access.

The Upper East Side cluster, which affected the Carnegie Hill and Yorkville neighborhoods, has now ended in terms of exposure.

However, investigation is still in progress to find out exactly how the outbreak began. Whole-genome sequencing results expected this fall could help determine whether the Legionella strain found in patients matches bacteria detected in nearby cooling towers.

One major change will connect the Health Department's cooling tower registration system with the Department of Buildings' construction permitting system.

The goal is to identify unregistered cooling towers before they begin operating, after the city found unregistered systems during both the Upper East Side investigation and a previous outbreak in Central Harlem.

New York will also create a citywide map of registered cooling towers, allowing residents to see their locations and review inspection histories, including whether buildings have complied with Legionella sampling requirements. The map and an annual public education campaign are expected by spring 2027.

Cooling tower owners cited for violations will receive the earliest hearing date permitted, which is 15 days after a summons is served.

Since May 8, the Health Department has conducted 800 field inspections, with more than 460 resulting in at least one violation. The city says $80,500 in fines have been paid.

Legionella bacteria can grow in warm water systems and become a health risk when contaminated water produces tiny droplets or mist that people breathe in.

Cooling towers are among the systems that can allow the bacteria to spread through the air. Most people exposed to Legionella do not become ill, but the risk is higher among older adults, smokers and people with chronic diseases or weaken immunities.

Speedy Testing And New Cooling Technology

As of August 31, 94 people had been diagnosed and 11 had died in the Upper East Side cluster. No patients remained hospitalized.

The Health Department plans to explore and implement faster culture-testing methods and other approaches that could reduce the time needed to confirm whether Legionella is present. This could be key in preventing future outbreaks.

The Upper East Side had nearly four times as many cooling towers in the affected area as were identified during the 2025 Central Harlem cluster, making rapid testing considerably more challenging.

The city will also establish a scientific team to examine new cooling tower technologies and alternative cooling systems.

NYC Health Commissioner Dr Alister F. Martin added, "Rigorous standards only matter if we are constantly working to make them stronger."

Parkinson’s disease has becoming increasingly common in the US, but new data show that the burden is heavier in some states than others.

An analysis of 2025 medical records of 46 million adults across 49 states found an evident geographic divide.

After adjusting for factors like age, sex, race, ethnicity and other health conditions, Nebraska recorded the highest rate at 561 Parkinson’s diagnoses per 100,000 people, followed by Kansas at 517 and Utah at 493. On the other hand, Montana recorded 308 diagnoses per 100,000.

Even though the findings do not prove that living in a particular state causes Parkinson’s, researchers say the pattern raises important questions about environmental factors, population differences and access to healthcare.

Why are Nebraska and Kansas seeing more cases?

More than 90% of Nebraska is farmed or ranched, while Kansas also has extensive agricultural activity. That signals that pesticides could be a possible contributor to Parkinson’s risk.

Dr Ayesha Bryant, a functional medicine physician, said that exposure to chemicals through farming could help explain the high rates in Nebraska, Kansas and possibly Arkansas. “The literature repeatedly shows associations between pesticide exposure and Parkinson's disease in epidemiological studies,” she told The Daily Mail.

Parkinson’s develops when dopamine-producing neurons progressively become damaged and die. Since dopamine plays a key role in movement, its loss can lead to tremors, stiffness, and slow movement.

Other pesticides, including paraquat and glyphosate, have also been investigated for possible links to Parkinson’s, although the evidence is not conclusive for all of them.

Air Pollution May Be Another Factor

Only around 20% of Utah is farmed or ranched, and pesticide use is also low. Yet it recorded the third-highest diagnosis rate.

Dr Rebecca Gilbert, neurologist and chief mission officer at the American Parkinson Disease Association, said air pollution is another environmental factor scientists are increasingly investigating. “Scientists are increasingly looking at air pollution as a possible risk factor for Parkinson's and other brain diseases, including dementia,” she said.

Utah's industrial and mining activity could contribute to exposure to fine particulate matter, or PM2.5. Research has increasingly explored whether long-term exposure to air pollution could affect brain health.

Talking about population as a factor, Dr Johnson Moon, neurologist and medical director for neurophysiology at Providence St Jude Medical Center, said that Utah's predominantly white population.

“Census data shows around 87 percent of residents are white – and Parkinson's is diagnosed more often in white populations than in black or Asian groups,” he said.

He added, “Genetic differences may partly explain this, although disparities in access to care and delayed or missed diagnoses among minority groups could also affect the figures.”

The US sees nearly 90,000 new Parkinson’s diagnoses each year, and more than 1.1 million Americans are estimated to be living with the disease. That number is projected to reach 1.2 million by 2030.

Age remains the biggest known risk factor, but genetics, environmental exposures and other factors may interact over decades. But as of now, scientists cannot point towards one definite cause of Parkinson's with certainty.

India is witnessing a shift in its disease landscape. While greater awareness, improved hygiene and national health policies have helped curb communicable and preventable diseases, the country is now facing a growing burden of metabolic conditions such as fatty liver and colorectal cancer, alongside persistent infections including Helicobacter pylori and intestinal worm infestations, health experts said.

The concerns come ahead of the World Congress of Gastroenterology (WCOG) 2026, to be held in India for the first time from September 30 to October 3 at Yashobhoomi, Dwarka, under the theme “Transforming Gastrointestinal Health, Preserving Nature.”

Fatty Liver a Major Concern

Fatty liver disease has emerged as a key metabolic health challenge in India. An AIIMS-led systematic review and meta-analysis found the condition in 38.6 per cent of Indian adults and 35.4 per cent of children. It is closely associated with diabetes, obesity and hypertension and can remain silent until liver damage progresses.

A recent study found that one in four patients with type 2 diabetes has clinically significant fibrosis.

“India is facing an epidemiological shift at this time. We have made significant strides in controlling preventable disease through awareness, vaccinations and improving quality of life, however alongside these we are now seeing metabolic disease on a scale we have never handled before,” said Dr. Pramod Garg, Professor and Head, Department of Gastroenterology and Human Nutrition, AIIMS, New Delhi.

“Fatty liver is the clearest example. The disease is easy to find if we look for it, and we become aware only after the patient falls ill. This is a greater challenge than before—we must move away from only treating diseases—we must now actively promote good health,” he added.

To address the rising burden, India included fatty liver disease in its National Programme for Prevention and Control of Non-Communicable Diseases in 2021, followed by guidelines for its detection at the primary-care level.

Colorectal Cancer Cases Growing Among Young

The experts also flagged colorectal cancer as a growing concern, with cases increasingly being seen among younger adults. India recorded 40,430 new cases among men and 24,433 among women in 2022.

“India has never been short of gastroenterologists or technology. What we have lacked is the habit of taking early symptoms seriously. We often misattribute our symptoms to stress or simply overlook them,” said Dr. Govind Makharia, Professor, Department of Gastroenterology and Human Nutrition, AIIMS, New Delhi.

“Every time we fail to identify a disease early, we lose the opportunity to potentially modify its natural history. Any symptom that persists beyond two to three weeks should be evaluated,” he added.

Persistent Infections and Chronic Gut Diseases

H. pylori remains widespread and is associated with peptic ulcer disease and gastric cancer. Intestinal worm infections continue to affect children and can contribute to anaemia and undernutrition.

Chronic gastrointestinal conditions such as celiac disease and inflammatory bowel disease (IBD) are also increasingly being recognized in India. Community-based research led by AIIMS found celiac disease in approximately one in 96 people in northern India.

Dr. Vineet Ahuja, Professor, Department of Gastroenterology and Human Nutrition, AIIMS, New Delhi, said conditions such as IBD and celiac disease, once considered rare in India, are now regularly encountered in clinical practice.

“Advances in endoscopy, artificial intelligence and microbiome research are improving diagnosis and treatment. The challenge now is to make these advances more widely accessible,” he said.

“With the advent of AI, we potentially stand at a new era of medicine—we must not dismiss it, but learn to adapt to it and improve the quality of care we provide to our patients,” he added.

The experts stressed the importance of early detection and urged people not to ignore persistent gastrointestinal symptoms, blood in the stool, unexplained weight loss or sustained changes in bowel habits. Earlier testing and preventive interventions can help identify and manage several GI conditions before they progress
