Cardiac-a-vest! Remarkable garment could save lives by predicting heart attack risk
Cardiac-a-vest! Remarkable garment could save lives by predicting heart attack risk
This groundbreaking vest could alert those with heart problems to a potential cardiac episode before it even happens.
Electrical signals orchestrate the rhythmic contractions of our hearts, regulating our heartbeat. Disruptions in these signals lead to heart rhythm disorders affecting two million people in the UK, potentially resulting in sudden death.
The electrocardiographic imaging (ECGI) vest, developed by researchers at University College London (UCL) and detailed in a recent Journal of Cardiovascular Magnetic Resonance paper, looks set to revolutionise heart electrical activity mapping. Traditional methods involved invasive catheters or single-use devices, both resource-intensive and often involving radiation.
The UCL-developed ECGI vest, funded by the British Heart Foundation and the Society for Cardiovascular Magnetic Resonance, offers a reusable and time-efficient alternative, requiring just five minutes per patient. Equipped with 256 sensors, the vest's electrical data combines with detailed MRI images to generate 3D digital models of the heart and its electrical activity waves. The doctors behind the insights will remarkable vest can be used as a screening tool and hope it may even identify those at the highest risk of a deadly episode before it occurs. The researchers aim to improve risk stratification, aiding in identifying individuals who may benefit from implantable cardioverter defibrillators (ICDs).
Inventor Dr. Gaby Captur noted, "We believe the vest we have developed could be a quick and cost-effective screening tool and that the rich electrical information it provides could help us better identify people's risk of life-threatening heart rhythms in the future."
Cardiologist Dr. Matthew Webber, co-developer of the vest, highlighted its ability to fill a crucial gap in heart imaging.
"Cardiac MRI, the gold standard in heart imaging, shows us the health of the heart muscle tissue, including where dead muscle cells might be," he said. "In-depth electrocardiographic imaging can help us correlate these features with their consequences - the impact they may be having on the heart's electrical system. It adds a missing part of the puzzle."

I would consider alfalfa to have some anti-inflammatory properties because it contains beneficial minerals and also chlorophyll. However, I wouldn't add it to your diet unless you like the taste of it. There are plenty of other foods with anti-inflammatory properties that are much more common. Some of these would be berries, salmon, broccoli, avocado, green tea, and there are so many more. Yes, alfalfa does have some anti-inflammatory properties and could potentially benefit your health.

Alfalfa, often consumed as sprouts in salads or by livestock, is a nutritious addition to a meal when eaten in moderation. Studies have shown that the active ingredients in alfalfa extract have been shown to have anti-inflammatory effects on the body. One such study showed a reduction in the inflammation caused by nicotine.

Dermatologist's insight on shower frequency without harming skin
Dermatologist's insight on shower frequency without harming skin
Some take a shower every morning and evening, while others only have water procedures a few times a week. It's worth knowing how often to shower to prevent dryness, itching, and skin irritation, according to the Express website.
What will happen if you shower frequently?
Dermatologist Jenny Liu mentions that many believe frequent washing, especially with soap or gel, can strip the skin's protective layer, leading to dryness, irritation, and itching.
However, she notes that daily showers or baths are very beneficial for the skin. This is recommended for people with dry or eczema-prone skin.
Soaking in a bath also helps moisturize the outer layer and improves exfoliation.
Many people, for various reasons, are accustomed to showering daily. Some enjoy the feeling of freshness and cleanliness after a shower, while others consider it a way to wake up or relax after a tough day at work.
Best ways to cleanse the skin
A daily shower or bath without using a moisturizer can damage the skin, especially if you aggressively cleanse and use harsh soap.
The dermatologist advises the following way of cleansing the skin:
Limit water contact to less than 15-20 minutes.
Use comfortably warm water, not too hot or too cold.
Apply moisturizer to damp skin immediately after showering or bathing to help retain moisture in the outer layer and prevent additional water loss.
Cold water
Naturopath Dr. Janine Bowring recommends finishing showers with cold water.
She explains that cold helps our leptin receptors, and addressing leptin resistance is necessary to balance hormones.
Washing the hair is recommended every 2-3 days, with oily hair possibly requiring more frequent washing and dry hair less often.
Earlier, we reported on four reasons why taking hot showers in winter might not be advisable.
We also covered five body parts that everyone tends to under-wash.
Meat is crucial for human health, scientists warn
Meat is crucial for human health, scientists warn
Meat is crucial for human health, scientists have warned, as they called for an end to the “zealotry” pushing vegetarian and vegan diets.
Dozens of experts were asked to look into the science behind claims that meat eating causes disease and is harmful for the planet in a special issue of Animal Frontiers.
They warned that it is difficult to replace the nutritional content of meat, arguing that poorer communities with low meat intake often suffer from stunting, wasting and anaemia driven by a lack of vital nutrients and protein.
In recent years, there has been a widespread societal push towards plant-based diets, with schemes such as Veganuary and meat-free Mondays encouraging the public away from meat.
The major Global Burden of Diseases, Injuries and Risk Factor Study, published in The Lancet in 2020, also suggested that a diet high in red meat was responsible for 896,000 deaths worldwide, and was the fifth leading dietary risk factor.
But researchers argue that unprocessed meat delivers most of the vitamin B12 intake in human diets, plays a major role in supplying retinol, omega-3 fatty acids and minerals such as iron and zinc, as well as important compounds for metabolism, such as taurine and creatine.
‘Fatally scientifically flawed’
In one paper published in the issue, experts found no good evidence to support red meat being dangerous below intakes of 75g per day, and argued that the link between red meat and disease vanished when part of a healthy diet, suggesting it was the rest of the diet that was fuelling health problems.
Dr Alice Stanton, of the Royal College of Surgeons in Ireland, one of the authors of the review, said: “The peer-reviewed evidence published reaffirms that [the 2019 Global Burden of Disease Risk Factors Report] which claimed that consumption of even tiny amounts of red meat harms health is fatally scientifically flawed.
“In fact, removing fresh meat and dairy from diets would harm human health. Women, children, the elderly and low income would be particularly negatively impacted.”
The NHS also advises that red meat – such as beef, lamb and pork – is a good source of protein, vitamins and minerals and can form part of a balanced diet, although it warns that eating more than 90g per day can raise the risk of bowel cancer.
The new edition includes a declaration signed by nearly 1,000 scientists across the globe arguing that livestock farming was too important to society to “become the victim of zealotry”.
The Dublin Declaration includes signatories from the universities of Cambridge, Edinburgh, Bristol, Belfast, Newcastle, Nottingham, Surrey as well as several scientists from Britain’s world-leading agricultural and farming university Harper Adams.
“Livestock-derived foods provide a variety of essential nutrients and other health-promoting compounds, many of which are lacking in diets even among those populations with higher incomes,” the declaration states.
“Well-resourced individuals may be able to achieve adequate diets while heavily restricting meat, dairy and eggs. However, this approach should not be recommended for general populations.”
The researchers warned that those who need to eat animal products included young children, adolescents, pregnant and lactating women, women of reproductive age, older adults and the chronically ill.
‘One-size-fits-all agendas’
Dr Wilhelm Windisch, a farming nutrition expert at the Technical University of Munich, said: “Farmed and herded animals maintain a circular flow of materials in agriculture by using and upcycling large amounts of materials humans cannot eat, turning them into high-quality nutrient dense food.
“One-size-fits-all agendas, such as the drastic reductions of livestock numbers could incur environmental and nutritional consequences on a massive scale.”
The intervention was welcomed by the National Farmers Union (NFU) who were this week promoting Great British Beef Week.
Richard Findlay, the NFU livestock board chair, said: “This peer-reviewed research confirms what we’ve always known – that red meat is a quality, nutritious protein that plays a critical role in a healthy, sustainable balanced diet.
“During Great British Beef Week this week, we can celebrate the sustainability of British beef and the environmental benefits our grazing herds deliver.”
The Global Burden of Diseases team had not responded at the time of publication.
