A stroke happens when blood flow to the brain is blocked or reduced, which can damage brain cells quickly. Because of this, fast treatment and prevention are very important to save lives and reduce long-term effects.

Preventing another stroke is a major focus for doctors and healthcare workers. They create treatment plans for patients, conduct regular health check-ups, and guide people to make healthier lifestyle choices. This may include changes in diet, exercise, controlling blood pressure, and managing conditions like diabetes.

In recent years, the use of artificial intelligence (AI) in healthcare has shown good results in improving stroke care. AI tools can help doctors detect early warning signs of stroke risk and support faster diagnosis.

These technologies also help doctors make better decisions about treatment by analyzing patient data quickly and accurately. This can lead to faster care, better recovery, and fewer complications for patients.

Experts believe that combining medical care with AI technology could play an important role in reducing the number of strokes in the future and improving survival rates worldwide.

As a doctor who treats patients with severe lung diseases and long COVID, I often get asked about the risks of new virus variants. So far, there’s no evidence that BA.3.2 is more dangerous than earlier versions of the virus. However, because it has changed so much from previous strains, the current vaccines might not protect against it as well.

BA.3.2 comes from the omicron variant, which first appeared in late 2021. The spike protein, which helps the virus enter cells and is targeted by vaccines, has 70 to 75 changes in BA.3.2 compared to other strains. This could make it harder for vaccines to work as effectively.

The variant was first spotted in November 2024 in Africa and started spreading globally in 2025. By February 2026, it had reached 23 countries. The first U.S. case was found in June 2025 in a traveler. Since then, it has been detected in 29 states through wastewater testing.

Viruses change over time, and COVID-19 evolves especially quickly. These changes can make the virus harder for the immune system to recognize. It’s like seeing someone after many years—they might look different enough that you don’t immediately recognize them.

Vaccines are designed based on the most common virus strains at the time. Right now, vaccines target JN.1 lineage strains, which have been dominant in the U.S. since early 2024. But BA.3.2 is so different that the vaccines might not protect against it as well.

This doesn’t mean you shouldn’t get vaccinated. Vaccines still reduce severe illness and death. But because they might not work as well against BA.3.2, it could spread more easily.

To stay safe:

1. Wash your hands often to lower your risk of infection.
2. Stay home when sick to avoid spreading the virus.
3. Spend less time in crowded places.
4. Talk to a doctor if you’re worried about your health risks.

While BA.3.2 might not be more severe, it’s still important to take precautions, especially for those with health conditions.

The study, titled “Technology Use and Screen Time Among Children,” surveyed 424 parents in India. It looked at how kids use screens and what parents think about it.

Parents reported that more screen time is linked to problems like poor self-control, too much gaming or social media, and trouble using devices responsibly. They also noted negative effects on children’s physical health, mental well-being, and social skills.

Rajesh Kumar, a psychology professor at NIMHANS, explained that parents are struggling to manage their kids’ tech use. This is especially true when it interferes with sleep, schoolwork, or daily routines.

Screen time guidelines vary by age, but many children exceed recommended limits. The study found that the more screen time kids have, the more worried parents get.

The most common issue was losing control over device use. Over half of parents said their kids got upset when devices were taken away or had trouble stopping using screens. Other worries included too much gaming, exposure to inappropriate content, and poor attention spans or grades.

Manoj Kumar Sharma, head of the SHUT Clinic, noted that problematic tech use isn’t just about how long kids spend on screens. It’s also about patterns like losing control or being overly engaged with devices.

The study also found that having more digital devices at home leads to more screen time. Kids in single-child households spent more time on screens, possibly because they have fewer siblings to interact with.

Tech is now part of daily life, used for learning and entertainment. But too much or poorly managed use can cause sleep issues, less physical activity, attention problems, emotional struggles, and social challenges. Early exposure without rules might also harm language skills and school performance.

The study didn’t diagnose addiction but focused on parent-reported signs of trouble. Parents said they need practical strategies, better communication, and improved digital skills to manage screen time.

Experts suggest that schools, pediatricians, and mental health services should help by offering guidance and training programs. The study calls for more research to understand long-term effects and family-centered solutions to address high screen use in kids.

mRNA vaccines work by teaching the immune system to identify and attack cancer cells, similar to how COVID-19 mRNA vaccines trained the body to fight the virus. When the immune system recognizes cancer cells as a threat, it can respond more quickly and strongly, reducing the growth of tumors. This approach could give doctors a new tool to target different types of cancer with more precision and fewer side effects compared to traditional treatments.

Since the early 2000s, scientists have conducted over 120 clinical trials testing mRNA vaccines for many types of cancers. These trials have included cancers such as melanoma, brain cancer, breast cancer, lung cancer, and prostate cancer. The studies have produced promising results, showing that mRNA vaccines can safely stimulate the immune system and, in some cases, help shrink tumors or slow their growth.

Experts believe that these vaccines could also help prevent cancer from coming back after treatment. By training the immune system to recognize cancer cells early, mRNA vaccines may improve long-term outcomes for patients and complement existing therapies like surgery, chemotherapy, and radiation.

Although more research is needed to fully understand the effectiveness and long-term benefits, the progress so far is encouraging. Scientists are optimistic that mRNA cancer vaccines may become an important part of cancer treatment in the near future.

This development highlights a larger trend in medicine toward personalized and targeted treatments, where therapies are designed to work with the body’s natural defenses rather than just attacking tumors. If successful, mRNA vaccines could change the way doctors treat cancer, giving patients safer, more effective options and new hope for recovery.

The original drug, produced by Danish pharmaceutical giant Novo Nordisk, is sold under the brand names Wegovy and Ozempic, and is widely used for diabetes management and weight loss. With the patent now expired in India, other companies can legally produce and sell cheaper versions of the medicine.

Before these recent launches, Natco Pharma and its partner Eris Lifesciences had already announced that their generic Semaglutide would be available from the first day of the patent expiry, March 20.

The entry of multiple generic manufacturers is expected to increase competition in the market and make the drug more affordable for patients. Industry analysts estimate that the market for Semaglutide in India could reach around $1 billion in the next few years, with more companies likely to join in and launch their versions.

This development is significant for patients with diabetes and obesity, as it provides more accessible treatment options. Experts say that generic drugs can dramatically reduce costs while maintaining the same effectiveness as branded medicines.

The launch of these generics also highlights the growth of India’s pharmaceutical sector, which continues to play a major role in supplying affordable medicines both domestically and globally.

Loss or change in taste is a common symptom during a COVID-19 infection and usually goes away within a few weeks. However, for some people, this problem continues for months or even years. This condition is often linked to what is known as Long COVID, where symptoms remain long after the initial infection.

To understand this better, researchers studied 28 people who were not hospitalised but still had taste problems more than a year after being infected with the virus. These participants reported ongoing issues with taste even after recovering from the illness.

The researchers used a method called the Waterless Empirical Taste Test to measure taste ability. The results showed that most participants had overall taste scores within the normal range. However, many still experienced specific problems. Only three people had very low overall taste ability, but 11 participants completely lost at least one type of taste, such as sweet, salty, sour, or bitter.

This shows that even if general taste ability seems normal, certain taste functions can still be affected. The study suggests that the problem may lie in how taste signals are processed at a microscopic level, rather than in physical damage to taste buds.

These findings are important because they help doctors better understand long-term symptoms of COVID-19. It also opens the door for new treatments that focus on restoring normal function at the molecular level. Overall, the study highlights that long-lasting taste problems are real and may need more attention and research to find effective solutions.

Research has shown that disruptions in the gut-brain axis are linked to various health issues, including irritable bowel syndrome (IBS), gastroesophageal reflux disease (GERD), inflammatory bowel disease (IBD), chronic fatigue syndrome, multiple sclerosis (MS), Alzheimer’s disease, Parkinson’s disease, and metabolic disorders. Maintaining a balanced gut microbiome is essential for preserving cognitive function and overall brain health.

Extra virgin olive oil has gained attention for its potential to support brain health by reducing inflammation and protecting brain cells from damage. Its high content of antioxidants, such as polyphenols, helps combat oxidative stress, which can contribute to age-related cognitive decline. Incorporating extra virgin olive oil into a healthy diet may help preserve memory, focus, and overall mental clarity as we age.

In summary, understanding the connection between nutrition and brain health is vital for promoting long-term cognitive function. By adopting a diet rich in beneficial foods like extra virgin olive oil, individuals can support both gut and brain wellness, potentially reducing their risk of neurodegenerative diseases and maintaining mental sharpness throughout life.

Early detection of Alzheimer’s is crucial because it allows for earlier intervention, potentially slowing the disease’s progression. However, developing methods to diagnose or even predict the disease before symptoms begin has been a major challenge.

Recent advancements in artificial intelligence (AI) have shown promise in addressing this issue. An AI tool has been developed that can predict Alzheimer’s with nearly 93% accuracy. This tool uses various types of data, including imaging tests like MRI scans, blood tests, and cognitive assessments, to identify early signs of the disease.

By analyzing this information, the AI tool can detect patterns that might indicate the onset of Alzheimer’s before it becomes apparent through traditional methods. This breakthrough is significant because it could lead to earlier treatment, which may improve outcomes for patients and help manage the disease more effectively in the future.
