Experiencing daytime sleepiness is something that is usually perceived as a minor inconvenience, but for older adults, it could be an early warning sign of Dementia. This neurodegenerative disease leads to the progressive decline of brain cells. This eventually

affects memory, cognition, and personality, making everyday tasks more difficult. As one of the fastest-growing neurological disorders across the world, dementia poses a significant health threat to ageing populations.

Is Dementia Linked To Poor Sleep?

For this study, researchers followed 445 older adults (average age 76) over three years, aiming to determine whether poor sleep could increase the risk of mild cognitive impairment (MCI), which often leads to dementia. At the start, none of the participants had MCI, but by the end of the study, 36 individuals had developed the condition.

The researchers discovered that participants with poor sleep were more likely to develop MCI compared to those who slept well. However, when depression symptoms were taken into account, the link between poor sleep and MCI became less pronounced, suggesting that while sleep issues are a concern, mental health also plays a key role in dementia risk.

To assess sleep quality, the Pittsburgh Sleep Quality Index (PSQI) was used, evaluating factors such as sleep duration, disturbances, and daytime alertness. Among these, "daytime dysfunction"—defined as excessive sleepiness and low energy during the day—was most strongly associated with an increased risk of MCI. Those experiencing daytime dysfunction were more than three times as likely to develop MCI as those who didn’t report such symptoms.

There are many types of dementia:

Dementia is not a specific disease. According to the Centers for Disease Control and Prevention (CDC), it is an overall term that describes a decline in mental ability that interferes with daily life. People with dementia often have symptoms like trouble remembering, thinking, or making everyday decisions. These symptoms tend to get worse over time.

Alzheimer’s disease is the most common type of dementia, and it mostly affects the elderly. Each form of dementia has a different cause. Though dementia mostly affects older adults, it is not a part of normal ageing. An estimated 6.7 million older adults have Alzheimer's disease in the United States. That number is expected to double by 2060, as per data from the CDC.

In 2022, 3.8% of men and 4.2% women in US were diagnosed with dementia. The percentage of people increase with age from 1.7% for those aged 65-74 to 13.1% for those aged 85 and older. Alzheimer's accounts for 60 to 80% of all dementia cases and it is most prevalent in California, Florida, and Texas, as these states have the highest number of people.

The American Red Cross reported a severe shortage of blood that has affected Tri-City area hospitals. In the last month, there has been a 35% drop in blood supply. The 'Code Red' blood shortage in Washington created a critical situation with hospitals requesting for blood. The drop is also noted due to the winter weather that has affected donation drive.

Red Cross Faces Blood Shortage: How Does Weather Influence Blood Bank?

Reports note that during the winter season, blood supply becomes challenging, though its demand may increase due to illness and severe weather conditions. However, the same factors lead to fewer donation drives that leads to critical shortage. According to Red Cross reports, more than 550 blood drives have been canceled since January 21. This has resulted in over 15,000 uncollected blood and platelet donation.

The shortage has severely impacted the availability of blood for trauma victims, cancer patients and those who require emergency surgeries. During such situation, volunteer donors play an essential role.

Diana Heilman, supervisor at the Kennewick Red Cross Fixed Site, said, "octors may face difficult decisions during a blood shortage, such as who can safely receive the products and treatments, and they will potentially have to wait because there simply isn't enough blood available."

Red Cross Faces Blood Shortage: What Is Affected?

• The Kennewick Red Cross identified a dire need of Type O blood, both positive and negative
• A negative
• B negative
• Platelets

Type O is a universal donor, while Type O positive is the most commonly transfused blood type. A negative blood type is found in only 6% of the population, and B negative is less than 2%.

Red Cross also announced a $20 e-gift card for those who donate between January 26 to February 28, as incentive.

Can Women Donate Blood During Their Period?

This is one of the most common concerns, especially among first-time female donors. According to Dr. Sangeeta Pathak, Director and Head of Transfusion Medicine at Max Super Speciality Hospital, Saket, who spoke to Health and Me, as per the Drugs and Cosmetics Act, women are advised not to donate during their menstruation, particularly during the 4-5 days of active bleeding. However, they are completely eligible to donate at any other time of the month if they are in good health.

Can You Donate Blood While Recovering From An Illness?

Health is key when it comes to blood donation. “A person should be completely healthy and free from fever or illness at the time of donation,” says Dr. Pathak. Moreover, certain medications can lead to deferral, and there is a comprehensive list maintained under the Drugs and Cosmetics Act. So if you’re on a prescribed course, it’s best to consult a doctor or the blood bank before donating.

Can You Donate Blood If You Have A Tattoo Or Piercing?

Yes. If you’ve recently had a tattoo or body piercing, you’ll need to wait 12 months before you can donate blood. This is a precautionary step to ensure there’s no risk of transmitting infections.

Statin pain and what is it, scientists finally explain. A study by University of British Columbia finally explained what statin muscle pain is and what triggers it. Statins have long been a cornerstone of cardiovascular care. By lowering “bad” LDL cholesterol, these drugs have significantly reduced the risk of heart attacks and strokes for millions worldwide. Yet, for a notable number of users, statins come with an uncomfortable trade-off: muscle pain, weakness, and, in rare cases, severe muscle breakdown that can even lead to kidney failure.

For years, doctors have known that these side effects occur, but not why. Now, a new study offers a detailed answer.

Researchers from the University of British Columbia (UBC), in collaboration with the University of Wisconsin–Madison, have identified the molecular trigger behind statin-related muscle problems. Their findings, published in Nature Communications, could pave the way for safer cholesterol-lowering drugs in the future.

Why Do Statins Affect Muscles?

Muscle-related side effects are among the most common reasons people stop taking statins. Symptoms range from mild soreness and fatigue to rhabdomyolysis, a rare but dangerous condition where muscle tissue breaks down and releases proteins that can damage the kidneys.

Until now, the biological mechanism behind this damage remained unclear. The new research zooms in on what happens inside muscle cells when statins are present.

Statin: The Role of Calcium in Muscle Cells

To understand the problem, researchers focused on a protein called the ryanodine receptor (RyR1), which plays a critical role in muscle contraction. RyR1 acts as a gatekeeper, controlling the release of calcium inside muscle cells. Calcium is essential for muscle movement, but only in carefully regulated amounts.

Using cryo-electron microscopy, an advanced imaging technique that allows scientists to view proteins in near-atomic detail—the team observed how statins interact with this receptor.

What they found was striking: when statins bind to RyR1, they force the channel to remain open. This leads to a constant leak of calcium into the muscle cell. Over time, this calcium overload becomes toxic, damaging muscle tissue and explaining the pain, weakness, and, in severe cases, muscle breakdown seen in some patients.

A Closer Look at How Statins Bind

The study examined atorvastatin, one of the most widely prescribed statins globally. However, researchers suggest the same mechanism may apply across the statin class.

They discovered that statins bind to RyR1 in an unusual three-part formation. One statin molecule attaches while the channel is closed, priming it to open. Two additional molecules then bind, forcing the channel fully open and keeping it that way. This sustained opening is what causes the harmful calcium leak.

This detailed binding pattern offers the clearest explanation yet for statin-induced muscle side effects.

What This Means for Future Treatments

While severe muscle injury affects only a small fraction of the more than 200 million statin users worldwide, milder symptoms are far more common and often lead patients to discontinue treatment. This is a serious concern, as stopping statins increases cardiovascular risk.

The new findings provide a potential solution. By modifying the parts of statin molecules that interact with RyR1—while preserving their cholesterol-lowering effects—scientists may be able to develop safer statins with fewer muscle-related side effects.

Why This Study Matters

Beyond statins, the research highlights how advanced imaging technologies are transforming medicine. By visualizing drug–protein interactions at near-atomic resolution, scientists can move from observing side effects to understanding their exact cause.

For patients, this could mean a future where statins remain just as effective—but far easier on the muscles, improving long-term adherence and overall quality of life.

Nipah virus outbreak in India triggered airport screenings of travelers. Many reports claim that passengers are being checked in similar ways as they were during the COVID-19 virus spread.

In Thailand, the screenings are happening in these following airports:

• Phuket International Airport
• Bangkok's Suvarnabhumi Airport
• Don Mueang Airport

Nipah Virus Outbreak In India: Why Is Thailand Gearing Up For COVID-19 Like Checks?

Two cases of Nipah virus were detected in India's eastern state of West Bengal, in Kolkata. While other airports have also geared up for travel checks, Thailand is taking it to a next level with COVID-19 like checks. The reason is due to a huge number of international travel form Kolkata to Bangkok and Phuket. Many reports claim that Thailand is a premier international destination for travelers from Kolkata, due to its proximity, affordability, and being a visa-free detination. There are roughly 55 weekly direct flights from Netaji Subhash Chandra Bose International Airport to Bangkok and Phuket.

Nipah Virus Outbreak In India: What Is It?

As per the World Health Organization (WHO), Nipah virus infection is a zoonotic illness that is transmitted to people from animals, and can also be transmitted through contaminated food or directly from person to person.

In infected people, it causes a range of illnesses from asymptomatic (subclinical) infection to acute respiratory illness and fatal encephalitis. The virus can also cause severe disease in animals such as pigs, resulting in significant economic losses for farmers.

Although Nipah virus has caused only a few known outbreaks in Asia, it infects a wide range of animals and causes severe disease and death in people.

Nipah virus is infectious and can spread from animals like bats and pigs to humans through bodily fluids or contaminated food. It can also pass between people through close contact, especially in caregiving settings. While it can spread via respiratory droplets in enclosed spaces, it is not considered highly airborne and usually requires close, prolonged contact for transmission. Common routes include direct exposure to infected animals or their fluids, consuming contaminated fruits or date palm sap, and contact with bodily fluids such as saliva, urine, or blood from an infected person.

Nipah Virus Symptoms

• Fever
• Headache
• Breathing difficulties
• Cough and sore throat
• Diarrhea
• Vomiting
• Muscle pain and severe weakness
