We all enjoy a good slushie every now and then. While they do not add any great nutritional value to our meal, they are a delightful snack made with shredded ice and sugar. To make them more accessible to people who cannot or do not wish to have sugar, there are many sugar free options to pick from. However, a recent study has revealed that sugar-free slushies containing glycerol, which is a sugar alcohol used to maintain their icy texture, can cause severe health problems in young children. The study was published in the journal Archives of Disease in Childhood, it explains that having these sugar free slushies can lead to children having a condition called "glycerol intoxication syndrome". In this condition there is a rapid drop in blood sugar, reduced consciousness, and a buildup of acid in the blood.

Rapid Onset of Symptoms

Kids who drank slushies with glycerol got sick very quickly. Within an hour, they started showing serious symptoms. Their blood sugar would plummet, sometimes dangerously low. Many became confused or lost consciousness, and some even had seizures. Doctors studied 21 children who got sick from these drinks between 2018 and 2024. Most of these kids were very young, seven years old or younger. By the time they got to the hospital, many were in bad shape, either unconscious or barely awake. This quick reaction time makes it especially scary, as parents might not realize the slushy is the cause right away. It's important to recognize these signs fast.

Why is Glycerol Harmful?

According to WebMD Glycerol is a type of naturally occurring alcohol, and it's used in lots of food products. You might find it in protein bars, diet foods, and even sugar-free candies. In slushies, it plays a key role in keeping the drink icy. Usually, slushies use tons of sugar to stop them from freezing completely. But because people are trying to cut back on sugar, companies are using glycerol instead. This is especially true in places with "sugar taxes," where sugary drinks cost more. So, to make sugar-free versions, they add glycerol. This switch means more kids are being exposed to this ingredient, which can be harmful to them.

What Does Glycerol Damage Children's Health?

The study explains that little kids are more at risk from glycerol because their bodies are still growing and developing. Their tiny bodies and young metabolisms might not be able to handle glycerol as well as adults' bodies can. This means that even a small amount can cause a big problem. Also, the amount of glycerol in a slushy can vary, and it's hard to know exactly how much is safe. Factors like how fast they drink it, if they've eaten recently, or if they've been exercising can also make a difference. Even the standard size of a slushy drink can be too much for a small child. This makes it hard to give a safe dose.

Health authorities in the UK and Ireland have already started warning about glycerol in slushies. They suggest that kids under four shouldn't have them at all, and older kids should only have one at most. But doctors are worried that these warnings might not be enough. They point out that it's hard to know how much glycerol is actually in each drink, making it difficult to give safe advice. Parents are being told to be very careful and consider avoiding these drinks altogether for young children. In the US, glycerol is approved for use in food, but parents should still be aware of the potential risks. More research is needed to understand the full impact.

Cancer is a complex disease, and its diagnosis often involves multiple tests, procedures, and high costs. Patients frequently undergo several blood draws and investigations before a clear result is reached.

Now, a revolutionary new low-cost test has shown promise in detecting multiple cancers using just a single blood sample.

Beyond cancer detection, the test may also help identify various liver conditions and organ abnormalities by analyzing DNA fragments circulating in the bloodstream.

The test, developed by scientists at the University of California, Los Angeles, is known as MethylScan. The novel test works by analyzing cell-free DNA, tiny fragments of genetic material released into the blood when cells die.

In early tests, MethylScan detected about 63 per cent of cancers across all stages and roughly 55 per cent of early-stage cancers.

The test, described in the journal Proceedings of the National Academy of Sciences, could offer a powerful and more affordable approach to early disease detection and comprehensive health monitoring.

“Early detection is crucial,” said Dr. Jasmine Zhou, Professor of Pathology at UCLA Health.

“Survival rates are far higher when cancers are caught before they spread. If you detect cancer at stage one, outcomes are dramatically better than at stage four,” Dr Zhou added.

How Does The New Cancer Test Work?

MethylScan studies DNA methylation—chemical tags on DNA that reflect tissue health and can change when disease develops.

Since most circulating DNA comes from healthy cells, advanced machine learning is used to identify subtle disease signals.

The New Cancer Test Is A Health Radar

In the study, MethylScan analyzed blood samples from 1,061 people, including patients with liver, lung, ovarian, and stomach cancers.

For multi-cancer detection, the test achieved a high level of overall accuracy. At a specificity of 98 per cent, meaning few false positives, it detected about 63 per cent of cancers across all stages and roughly 55 per cent of early-stage cancers.

The test also performed well in liver cancer surveillance among high-risk individuals, including those with liver cirrhosis or HBV. It detected nearly 80 per cent of cases at a specificity of just over 90 per cent, meaning a less than 10 per cent false positive rate.

The blood test could also distinguish between different types of liver disease, including viral hepatitis and metabolic-associated liver disease. It correctly classified about 85 per cent of patients, suggesting blood-based DNA testing could reduce the need for invasive liver biopsies.

In addition, the researchers noted that MethylScan can work like a health radar for the body. By reading DNA signals in the blood, it can tell when specific organs, such as the liver or lungs, are under stress or damaged, even without knowing the disease in advance.

“This study demonstrates that blood-based methylation profiling can deliver clinically meaningful information across multiple diseases,” said Zhou. “It’s an exciting advancement that brings us closer to realizing the dream of a single assay for universal disease detection.”

Most people assume dandruff simply means white flakes. In clinical practice, however, we commonly see two different patterns—oily dandruff and dry dandruff. Both can cause flaking and itching, but the scalp environment, type of flakes, and recurrence pattern can differ significantly. Understanding which type you have helps in choosing the right scalp care. Using random shampoos without understanding your scalp often provides only temporary relief, and the flakes keep returning.

Dr Ankur Sarin, Dermatologist at Sarin Wellness and Co-founder, sarinskin.com, in an interview with Health and Me, explained the differences and management approaches.

What Causes Dandruff?

Dandruff is a common scalp condition linked to an imbalance involving a naturally occurring yeast called Malassezia. This organism lives on most human scalps and feeds on sebum, the natural oil produced by the scalp.

In some individuals, the scalp becomes sensitive to the by-products produced when this yeast breaks down sebum. This irritation can lead to inflammation and faster turnover of skin cells.

Normally, scalp skin sheds invisibly. However, when cell turnover speeds up, these cells accumulate and appear as visible flakes. Mild itching, irritation, and redness can also occur. The amount of oil present on the scalp often influences how dandruff appears, which is why the condition can show up as either oily or dry flaking.

Oily Dandruff: When Excess Oil Drives the Flaking

What It Looks Like: Oily dandruff usually appears as yellowish or off-white flakes that look slightly sticky or clumped together. These flakes often stick to the scalp or nails rather than falling freely on clothing.

What It Feels Like: The scalp may feel greasy within one or two days after washing. Itching is usually persistent but moderate. Some people may also notice mild redness.

What’s Happening on the Scalp

Excess sebum creates a favourable environment for Malassezia yeast to grow more actively. Factors that can worsen oily dandruff include:

1. Humid weather
2. Sweating
3. Helmet use
4. Heavy styling products
5. Infrequent scalp cleansing

Simply washing more often or using cosmetic shampoos may remove surface oil temporarily, but they do not control yeast growth, so flakes tend to return quickly.

Dry Dandruff: Fine Flakes That Fall Like Snow

1. What It Looks Like: Dry dandruff appears as fine, powdery white flakes that easily fall onto the shoulders, especially visible on dark clothes.
2. What It Feels Like: The scalp may feel slightly tight or dry. Itching is usually mild to moderate rather than intense.

What’s Happening on the Scalp

Dry dandruff is often confused with simple scalp dryness caused by cold weather, harsh shampoos, or over-washing. However, recurrent fine flaking is still frequently associated with Malassezia-related irritation, even if the scalp does not feel very oily. This means that simply increasing oiling or switching to moisturising shampoos may improve comfort but may not completely resolve the flaking.

Why Each Type Needs Slightly Different Care

The key difference between oily and dry dandruff lies in scalp oil levels and flake texture.

1. Oily dandruff requires controlling excess oil along with antifungal action.
2. Dry dandruff requires maintaining scalp balance without excessive stripping while still addressing yeast activity.

Many regular shampoos simply cleanse the hair. They may wash away flakes temporarily but do not treat the underlying microbial imbalance. For better control, it helps to look for clinically studied antifungal ingredients. One such ingredient is piroctone olamine, which helps reduce the growth of dandruff-associated yeast.

Benefits of Piroctone Olamine in Scalp Care

1. Effective antifungal activity
2. Gentle on the scalp barrier
3. Suitable for regular use
4. Works across different climates and scalp types

Consistent use helps maintain scalp balance and reduce recurrence.

How to Identify Your Dandruff Type

A few simple observations can help:

1. Does your scalp become greasy quickly after washing?
2. Are the flakes sticky and clumped?
3. Or are they fine and powdery?
4. Do flakes persist even when you moisturise the scalp?

A simple home check is to press a small strip of butter paper on the scalp parting. If it quickly shows oil marks, your scalp may lean towards the oily side.

The Takeaway

Checking the ingredient list and using shampoos with proven antifungal ingredients regularly can help maintain long-term scalp health. Consistency matters — because dandruff is a recurring condition that needs ongoing scalp care, not a one-time fix.

World Asthma Day is observed globally every year on the first Tuesday of May to raise awareness about the most common chronic non-communicable disease in the world.

The condition affects over 260 million people. It is also responsible for over 450,000 deaths each year worldwide. However, most of these deaths are preventable.

As per the Global Burden of Disease Report (GBDR) 2019, India has the highest and growing burden of asthma in the world in terms of deaths and disability-adjusted life years, and over 3.4 crores of people in India have asthma, despite accounting for only 13 per cent of the world's asthma population, and 42 per cent of global asthma mortality.

World Asthma Day: History

World Asthma Day began in 1998 during the first World Asthma Meeting in Barcelona, Spain.

Coordinated by the Global Initiative for Asthma (GINA), with over 35 countries initially participating, it has grown into a global awareness event held annually on the first Tuesday of May.

GINA is a World Health Organization collaborative organization founded in 1993.

World Asthma Day: Theme

This year, the theme is: “Access to anti-inflammatory inhalers for everyone with asthma – still an urgent need”.

The theme reinforces that every person with asthma, including most pre-school children with asthma, should receive inhaled corticosteroids.

These inhalers reduce the person’s risk of asthma attacks and preventable asthma deaths.

GINA continues to emphasize the need to ensure that all people with asthma can access inhaled medications that are essential for controlling the underlying disease and treating attacks.

Preferably, the inhaler should be a combination 2‑in‑1 inhaler containing both an inhaled corticosteroid and a quick-acting reliever. Together, they treat the asthma symptoms, prevent asthma attacks, and reduce hospital admissions.

What is Asthma? Signs and Symptoms

Asthma attacks are mainly caused by the obstruction of the air passages in the lungs, which reduces the ability of the person to inhale life-sustaining oxygen into the body.

The airway obstruction is caused by spasm and tightening of the airway muscles, and inflammation, which causes both swelling of the walls of the air passages and mucus or phlegm blocking the airways.

Common symptoms include

• shortness of breath,
• wheezing (a whistling sound on exhaling),
• chest tightness or pain,
• coughing—often worse at night, early morning, or during triggers like colds, exercise, allergens, or smoke.

How To Treat Asthma

According to GINA, inhaled corticosteroids are essential for treating and controlling asthma.

The short-acting bronchodilator relievers (salbutamol, albuterol, terbutaline, SABAs) only relieve the spasm and tightening of the muscles in the air passages, but inhaled corticosteroid-containing medications prevent asthma attacks by treating the underlying inflammation that causes asthma.

The inhaled corticosteroid-containing medication should be prescribed in addition to, or in combination with, reliever medication, to prevent the continuing avoidable morbidity and mortality from asthma.

In low-middle-income countries, lack of availability or high cost of inhaled medicines, especially inhaled corticosteroid-containing inhalers, are major contributors to the fact that many attacks and 96 per cent of global asthma deaths occur in these countries.

How To Prevent Asthma

Asthma can be prevented by:

• Avoiding exposure to environmental triggers such as air pollution, cold air, fragrances, etc.
• Avoiding contact with allergens.
• Avoiding smoke from cigarettes, candles, incense, and fireworks. Staying away from sick people (cold or the flu)
• Keeping the surroundings dust-free
• Taking vaccinations on time to prevent pneumonia, diphtheria, tetanus, the zoster vaccine, and whooping cough
• Adhering to asthma medications.
