A recent study suggests that people who donate blood regularly may have genetic changes in their blood that could in fact reduce the risk of developing cancer. It is conducted by the researchers at the Francis Crick Institute, and the study has now provided new insights into how and why blood cancers develop. The study is published in the journal Blood and was conducted by the scientists from Heidelberg and the German Red Cross blood donation center. There is yet a need for further research to confirm these findings.

What Did The Study Find?

The researchers examined the blood of two groups of healthy male donors in their 60s:

• One group had donated blood three times a year for 40 years.
• The other group had donated only about five times in total.

The goal was to analyze genetic mutations in their blood and assess whether frequent donation had any impact on their genetic makeup.

How Can Blood Donation Affect Stem Cells?

As and when people age, their blood and other cells naturally develop mutations and some of them can also increase the risk of cancer. When anyone donates blood, his or her body compensates by producing new blood cells, which can influence the genetic diversity of stem cells in the bone marrow. The study also found that both groups had a similar number of mutations. For instance the frequent donors had 217 mutations, while the irregular donors had 212 mutations.

However, the nature of these mutations differed. In the frequent donors, 50% of the mutations were of a type not associated with a high risk of blood cancers, compared to only 30% in the irregular donors.

Further laboratory analysis showed that these specific mutations behaved differently from those linked to leukemia, a type of blood cancer. When human blood stem cells with these mutations were injected into mice, they were found to be highly effective at producing red blood cells, which is considered a positive outcome.

Dr. Hector Huerga Encabo, one of the study authors, emphasized that these mutations do not indicate an increased risk of leukemia. The findings suggest that regular blood donation may influence how stem cells evolve, but whether this translates into a lower cancer risk remains uncertain.

Limitations

One notable disadvantage is the "healthy-donor effect"—because blood donors are often healthier than the general population, their lower cancer risk could be unrelated to blood donation.

Dominique Bonnet, senior researcher and head of a stem-cell laboratory at the Francis Crick Institute, stressed the need for larger studies with female volunteers to confirm the findings.

Despite ongoing research into potential health benefits for donors, the primary goal of blood donation remains saving lives. NHS Blood and Transplant emphasized that while the study is interesting, further research is required to draw firm conclusions. The organization also noted that blood supplies are currently critically low and encouraged eligible individuals to donate.

Prateek Yadav (38), the son of late Samajwadi Party founder Mulayam Singh Yadav, died due to a massive blockage in the blood vessels of the lungs, leading to a collapse of the heart and respiratory system, as revealed in the postmortem examination report.

According to the autopsy findings, the provisional cause of death was recorded as “cardiorespiratory collapse due to massive pulmonary thromboembolism.” In simple terms, doctors said a large blood clot had blocked blood flow to the lungs, causing his heart and breathing to fail.

What Is Pulmonary Thromboembolism?

An embolism is any object (clot, fat, air, tissue) traveling through the bloodstream that becomes stuck, blocking blood flow. A thromboembolism is a specific type of embolism where that travelling object is a piece of a blood clot (thrombus) that has broken off from its original site.

It is a life-threatening condition that happens when a blood vessel in the lungs is blocked by a blood clot.

The common symptoms may include:

• Difficulty in breathing
• Chest pain
• Cough up blood

The blood clot starts in a deep vein in the leg and travels to the lung in most cases. Rarely, the clot forms in a vein in another part of the body, noted Mayo Clinic. When a blood clot forms in one or more of the deep veins in the body, it is called a deep vein thrombosis or DVT.

Other symptoms of pulmonary embolism include:

• irregular heartbeat
• lightheadedness or dizziness
• excessive sweating
• fever
• leg pain or swelling, usually in the back of the lower leg
• clammy or discolored skin

Lung Infection Claims Life of Karnataka Minister

Meanwhile, Karnataka's Planning and Statistics Minister, D. Sudhakar (66), passed away after a prolonged battle with a lung infection.

The most common lung infections that people experience are pneumonia, bronchitis, tuberculosis, influenza-related infections, and severe viral illnesses.

Experts noted that these lung infections cause fluid or pus to fill the air sacs, which prevents oxygen from entering the bloodstream.

"What may initially appear as a routine cough, fever, or chest infection can progress to severe pneumonia, respiratory failure, sepsis, or permanent lung damage,” Dr. Vikas Mittal, Director - Pulmonologist, CK Birla Hospital, Delhi, told HealthandMe.

Warning signs include

• worsening breathlessness,
• persistent fever,
• chest pain,
• bluish lips,
• confusion,
• falling oxygen levels should never be ignored.

Dr. Nikhil Rajvanshi, Consultant - Paediatric Pulmonology, Rainbow Hospital, Delhi, told HealthandMe that children may be more at risk of pulmonary infections as they can become dangerous quickly because their lungs and immune systems are still developing.

Common illnesses such as bronchiolitis, pneumonia, influenza, and other viral infections may rapidly lead to breathing difficulty, low oxygen levels, dehydration, and respiratory distress. Infants, premature babies, malnourished children, and those with asthma or congenital disorders are at higher risk of complications.

The experts called for

• early medical evaluation
• timely treatment
• vaccination
• good hygiene practices,
• quit smoking,
• maintaining immunity.

US President Donald Trump's attempt to clarify the meaning of "sea" while discussing drug smuggling has again raised concerns of dementia.

While the 79-year-old President rambled between “sea and see” in the middle of discussing drug problems in the US, social media went rife with the rumor of his cognitive decline.

"Drugs coming by sea meaning coming by water. A lot of people don’t know what I mean by sea. They think I mean vision. I’m talking about sea like the sea," he said. He was speaking at the White House, while hosting law enforcement officials for a dinner in the Rose Garden in celebration of National Police Week.

His comments were called out by social media as his apparently worsening cognitive capabilities.

"When he says 'a lot of people' he means 'me.' His cognitive issues are a crisis," one social media user declared, while another admitted, "He’s getting worse."

Trump has spoken on sea and see, during a maternal healthcare event last week, where he also referred to himself as the “father of fertility.”

Earlier, speaking at the White House Small Business Summit, Trump said he has taken the Montreal Cognitive Assessment three times and “aced each one,” claiming a doctor told him it was the first time they had seen a perfect score, The Daily Beast reported.

The US President said he answered the test questions easily, suggesting he is cognitively in good condition—a claim that critics have repeatedly questioned.

“The first question is very easy,” he said. “You have a lion, a bear, an alligator, and a—what’s another good…? A squirrel. Which is the squirrel?” He added that the difficulty increases as the test progresses. “By the time you get to the middle, they’re very tough.”

However, the test’s creator, Canadian neurologist Ziad Nasreddine, has challenged Trump’s claims. “It wasn’t designed to be a test of IQ,” he told nine.com.au. “It was designed to assess normal cognitive performance.”

Experts Claim Trump's Mental Health Is Deteriorating

A group of medical experts, including neurologists, psychiatrists, and other physicians, has sounded the alarm over what they’ve described as Trump’s deteriorating mental health.

The experts have not specifically examined Trump face-to-face. But, they analyzed Trump's statements and behaviors over the past year, and stated that he’s “mentally unfit” and must be removed from office “with the greatest urgency” amid the escalating tension around the world, according to their statement published in The BMJ.

“It is our professional opinion that they (Trump's statements) reflect a rapidly worsening, reality-untethered, increasingly dangerous decline,” the experts said.

They also listed some of Trump’s observable serious medical issues, such as “Marked deterioration in cognitive functioning, evidenced by disorganized and tangential speech, rambling digressions, factual confusions, unexplained sudden changes of course in strategic matters, both national and international, episodes of apparent somnolence during critical public proceedings.”

What The White House Says

The White House has continued to say that Trump remains in strong health.

In October 2025, White House physician Captain Sean Barbabella said the president “continues to demonstrate excellent overall health,” AOl.com reported.

"President Trump’s sharpness, unmatched energy, and historic accessibility stand in stark contrast to what we saw during the last administration when Democrats and other lunatics intentionally covered up Joe Biden’s serious mental and physical decline from the American people,” White House spokesman Davis Ingle was quoted as saying to The Daily Beast.

From Polycystic Ovarian Disease (PCOD) to Polycystic Ovary Syndrome (PCOS) and now Polyendocrine Metabolic Ovarian Syndrome (PMOS) — confused about what the changing terminology means for women’s health and treatment?

What was once seen mainly as a reproductive or ovarian disorder is now being recognized as a complex hormonal and metabolic condition that can affect everything from periods and fertility to weight, insulin resistance, heart health, skin, and mental well-being.

To better understand the distinction between the three, let’s look at how the condition has evolved.

The condition, involving irregular periods, infertility, excess facial hair, and enlarged ovaries containing multiple cysts, was first identified as an ovarian or reproductive disorder in the 1930s by American gynecologists Dr. Irving Stein and Dr. Michael Leventhal. It became known as Stein-Leventhal Syndrome.

Over the years, the term PCOD became widely used, especially in countries like India. The name focused mainly on the presence of multiple ovarian cysts seen on ultrasound scans. It was considered a “disease” affecting ovulation and fertility.

Further, in the 1980s and 1990s, experts discovered that the condition involved hormonal imbalances, insulin resistance, weight gain, diabetes risk, and heart health concerns, among others.

Because it affected multiple body systems, PCOS became the medically preferred global term. The word “syndrome” was used to describe a group of related symptoms rather than a single disease.

However, many experts argued that the name still overemphasized ovarian cysts and fertility, and in 2012, the US National Institutes of Health (NIH) officially recommended changing the name, saying it was misleading because:

• Not all women with the condition have cysts
• Ovarian cysts alone are not enough for diagnosis
• The name ignores the metabolic and hormonal aspects

In 2026, global experts publishing in The Lancet proposed the new name -- PMOS – for the condition affecting more than 170 million women worldwide.

The new term PMOS acknowledges that the condition involves:

• Endocrine health
• Metabolic health
• Reproductive health
• Dermatological health
• Psychological health.

What Does PMOS Mean?

The new name aims to explain the condition more accurately and comprehensively.

Polyendocrine means it affects multiple hormones in the body.

Metabolic refers to issues linked to weight, insulin, blood sugar, and heart health.

Ovarian highlights its impact on ovulation and reproductive health.

Syndrome refers to a group of symptoms occurring together.

In simple terms, PMOS is a hormonal and metabolic condition that can affect periods, fertility, skin, mood, weight, and long-term health.

What The Name Change Means For Women

Speaking to HealthandMe, Dr Monika Bhatia Director — Obstetrics & Gynaecology Robotic and Laparoscopic Surgeon Cloudnine Group of Hospitals, said that the earlier name was misleading because the "cysts" in PCOS are not real cysts — they are simply small, arrested follicles.

While the name has changed, the message remains the same.

“Behind every diagnosis is a woman trying to understand her body, hormones, emotions, and health. While this condition may affect periods, fertility, metabolism, skin, weight, or mental well-being differently, one thing remains common — it is manageable with the right guidance,” she said.

The core treatment stays the same as the guidelines for treatment have not changed, but the approach becomes wider.

“So instead of just treating the periods, PMOS is now managed as a whole-body condition involving a multidisciplinary team”.

Will there be any change to evaluation?

Dr Muskaan Chhabra, Fertility Specialist, Birla Fertility & IVF, Lajpat Nagar, told HealthandMe that the new name –PMOS- correctly acknowledges that this is a multisystem condition involving complex interactions between insulin, androgens, and neuroendocrine hormones.

In PMOS, the ovaries are one of several systems involved rather than the primary site of the problem.

This “opens the door to more comprehensive clinical evaluation, earlier and more accurate diagnosis, and treatment approaches that address the full hormonal and metabolic picture rather than a narrow reproductive one,” Dr Muskaan said. It will also “drive more integrated and personalized care”.
