In another news, a new device Tendyne transcatheter mitral valve replacement (TVMR) system has been approved by the US Food and Drug Administration (FDA) for the treatment for patients who are suffering from severe mitral annular calcification (MAC). The prominent player in this is Abbott Laboratories who earned the FDA approval for the device.

What Is the TVMR system?

The Tendyne system is designated for those who are at high risk for traditional open-heart surgery. It helps with those with mitral valve disease, as it can cause debilitating symptoms like chest pains, shortness of breath, and dizziness due to heart's impaired ability to pump blood effectively.

As per experts of valve diseases, the challenges that patients with mitral annular calcification face could be reduced with the help of Tendyne system.

It is also designed for its adaptability to various patient anatomies. Furthermore, the surgery is minimally invasive and involves only a small incision in the chest. The valve is also responsible for repositionable and retrievable during the implantation process, ensuring optimal placement.

What Is Mitral Annular Calcification?

As per a 2020 study published in the Indian Journal of Thoracic and Cardiovascular Surgery, titled Mitral annular calcification: challenges and future perspectives, MAC is a chronic degenerative process that implies calcification on the mitral support structure.

It was first described in 1908 by Bonninger, as associated with complete heart block. Dewitzky presented detailed pathologic descriptions of 36 cases and demonstrated the close resemblance to a similar process that had been described in the aortic valve in 1904 by Monckeberg. Yater and Cornell in 1935 histopathologically demonstrated extension of a calcific mass into the Bundle of His leading to heart block.

What exactly happens in this condition is that there is a buildup of calcium deposits, along the mitral annulus, the fibrous ring that supports the mitral valve. It is also common among older individuals and is often discovered incidentally during imaging for other reasons. While people with MAC may not have symptoms, it can progress to cause issues like mitral stenosis, which is narrowing of the valve or mitral regurgitation, which means leaking of the valve.

Why It Happens?

As it is a degenerative process, it is thus potentially linked to factors like aging, atherosclerosis, and other cardiovascular risk factors. It is also linked to conditions like hypertension, diabetes, and chronic kidney disease.

Severe MAC can often lead to serious complications like heart failure, stroke, or even death.

Diagnosis

It is typically diagnosed through imaging technique like echocardiography or cardiac CT. Echocardiography can show the calcifications as bright, reflective structures on the ultrasound.

Finance Minister Nirmala Sitharaman has announced a surprising tax reduction for India's fishers and marine industry, and experts say it is good news for you too.

Until now, fish caught by Indian vessels beyond territorial waters and brought back to the country for mass consumption has been treated as import, attracting customs duties and integrated goods and services tax (GST).

The combined tax burden raises costs and compliance issues, which discouraged people from deep-sea and exclusive economic zone (EEZ) fishing as well as

However, during her Union Budget 2026 presentation, Sitharaman proposed that fish caught in the EEZ and high seas by Indian fishing vessels are treated as duty-free when brought into Indian ports and treated as exports when landed at foreign ports.

This means that the market availability for Omega-3 packed fishes including salmon, mackerel, tuna, herring and sardines will significantly increase as their existing steep prices see a tremendous fall.

What Are Fish Oil Omega-3s?

Omega-3 fatty acids are polyunsaturated fats known for their crucial role in brain function and overall mental health. Fish oil is particularly rich in EPA and DHA, which are vital components of cell membranes and have strong anti-inflammatory effects in the body.

These omega-3s play a critical role in human development, and they are primarily found in fatty fish and fish oil. Since many people do not consume enough fish, supplementation is often recommended to ensure adequate intake of these essential fatty acids.

Although the body can convert another type of omega-3, alpha-linolenic acid (ALA), into EPA and DHA, this process is not highly efficient. As a result, fish oil supplements may provide a convenient way to ensure optimal levels of omega-3s.

Some popular sources of Omega-3 include:

• Salmon
• Cod Liver Oil
• Algae Oil
• Oysters
• Nuts and seeds, such as flaxseeds, chia seeds, and walnuts
• Plant oils, such as flaxseed oil, soybean oil, and canola oil
• Fortified foods, such as eggs, yogurt, juices, milk, etc.

How Omega-3s Improves Brain Health

EPA and DHA are essential for maintaining brain function throughout life. These fatty acids are abundant in the brain's cell membranes, helping to preserve cell health and facilitate communication between brain cells.

Research has shown that a lack of omega-3 can lead to cognitive impairments. In animal studies, diets deficient in omega-3s resulted in reduced DHA levels in the brain, leading to deficits in learning and memory. In older adults, lower DHA levels have been linked to a smaller brain size, which may indicate accelerated brain ageing.

Maintaining sufficient levels of omega-3s can help support cognitive function and may reduce the risk of age-related brain decline.

The optimal dosage varies, but research suggests that 1,000–2,000 mg of omega-3 fatty acids from fish oil daily is a good starting point. People with depression should look for supplements with higher EPA content. It is pertinent to note that people should consult health experts before starting fish oil supplementation.

Import Duty Decreased On Cancer Drugs

These imported, specialized cancer treatments, particularly targeted therapies and monoclonal antibodies, often cost thousands, placing a massive financial burden on patients, leading to lifelong debts.

In this year's Union Budget, Sitharaman also proposed reducing import duty tax on 17 cancer drugs and seven medicines for rare diseases, which will in turn, help patients seek proper care on a timely basis.

Deshmukh commented: "India is witnessing a steady and alarming rise in cancer cases, where late detection, prolonged treatment and high medicine costs often lead to preventable complications and loss of life. Against this backdrop, the Union Budget’s decision to remove customs duty on 17 cancer drugs and 7 medicines for rare diseases stands out as a truly progressive and patient-first measure.

"Affordability remains one of the biggest hurdles in cancer care, forcing many families to delay or discontinue treatment. By reducing import duties, this move has the potential to significantly lower the cost of advanced and targeted therapies, making them accessible to a larger section of patients."

Experts are cautioning US of a potential Nipah virus outbreak, especially through international travels. Countries across Asia have already started airport health screenings. Thailand has geared up as it receives a high number of travelers from Kolkata, where the two cases of Nipah virus were detected.

Experts Reveal Risks Of Nipah Virus Outbreak: What Are They Saying?

Dr Krutika Kupalli, a Texas-based expert who formerly also worked with the World Health Organization (WHO), told The Daily Mail that the possibility of Nipah virus outbreak is 'absolutely' something the Centers for Disease Control and Prevention (CDC) should be 'closely monitoring'.

“Nipah virus is a high-consequence pathogen, and even small, apparently contained outbreaks warrant careful surveillance, information sharing, and preparedness. Outbreaks like this also underscore the importance of strong relationships with global partners, particularly the WHO, [which] plays a central role in coordinating outbreak response and sharing timely, on-the-ground information," she said.

A CDC spokesperson told The Daily Mail that the agency is in 'close contact' with authorities in India. "CDC is monitoring the situation and stands ready to assist as needed."

Experts Reveal Risks Of Nipah Virus Outbreak: What Is Happening In India?

Nipah virus outbreak reported in West Bengal, India started with the cases of two nurses, one of whom has now been discharged.

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.

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.
