“I'm not great at the advice. Can I interest you in a sarcastic comment?”

This is what ‘Friends’ actor Matthew Perry’s character Chandler Bing was known for. He was known for being funny. However, he had his own struggles in his personal life and those struggles were acute depression. He was treating it with ketamine infusion therapy which is legal in the US and the UK.

What is Ketamine infusion therapy?

Ketamine is an anaesthetic used to treat depression, anxiety and pain under supervised and controlled medical settings. However, it does have its side effects, which can lead to distortion of sight, sound and time. It can also produce calming and relaxing effects.

Ketamine increases a person’s heart rate and blood pressure. If overdosed, it can leave users confused and agitated and can cause them to hurt themselves without even realising it. It can also lead to liver damage and bladder problems.

However, when used in moderation and under the supervision of medical doctors, it can treat depression where traditional antidepressants have failed.

Prof Rupert McShane, a University of Oxford psychiatrist who runs an NHS ketamine treatment clinic told BBC that ketamine “probably turns off the area of the brain that is involved in disappointment.”

Can Ketamine Infusion Therapy Kill Someone?

In simple terms, it cannot, be if the dosage is given in a controlled setting and as prescribed. Ketamine infusion therapy uses drugs in small doses than those used for anaesthesia. It acts faster than traditional anti-depressants, but the effects also wear off way quickly. Which is why it is important to monitor patients’ mental state for relapsing back into depression and discouraging them from overdosing on it.

There are ways of giving people ketamine. One of the ways is through “infusing”, which means to use an IV drip. However, injections, nasal sprays and capsules are also methods used to give people ketamine.

Since the dosage of ketamine used in the infusion treatment is small, it being the reason of actor Perry’s death was ruled out. The medical examiner also noted that Perry’s last ketamine infusion therapy session happened more than a week before his death, which means by the time he had died, it must have worn off.

So, What Happened To Perry?

Though Perry’s last session was more than a week before, his post-mortem showed that his blood contained a high concentration of ketamine. He had died of the “acute effects” of ketamine.

If it was not his session, then how did he get ketamine?

Prosecutors alleged that his assistant gave him at least 27 shots of ketamine in four days before his death, reported BBC.

Perry has been open about his personal struggles and this is what the doctors and dealers used against him. Martin Estrada, the US attorney for California’s Central District told the BBC that people took advantage of his condition. They charged him 165 times more than what vials of ketamine cost.

Names that have come up include Dr Salvador Plasencia, drug dealers “Ketamine Queen” aka Jasveen Sangha and Eric Fleming, and Perry’s live-in assistant Kenneth Iwamasa.

Who Are These Names And What Did They Do?

Ketamine Queen or Sangha supplied drugs that led to Perry’s death. Her home was a “drug-selling emporium,” said Estrada. More than 80 vials of ketamine, and thousands of pills including methamphetamine, cocaine and Xanax were allegedly found in her house known as the “Sangha Stash House.”

Sangha is known to deal with high-end celebs and was a “major source of supply for ketamine to others as well as Perry,” said Estrada.

Dr Plasencia called Perry a “moron” while charging him $2,000 for vials that cost only $12. He sold Perry 20 vials of ketamine between September and October 2023, costing $55,000.

He was the one who taught Iwamasa, who had no medical knowledge to inject the drug. This is after he knew that “Perry’s ketamine addiction was spiralling out of control,” as per what the investigators told the BBC.

Another dealer Fleming was told by Sangha to “delete all our messages.” While Fleming pleaded guilty to conspiring to distribute drugs unlawfully, he also allegedly messaged Sangha: “Please call...Got more info and want to bounce ideas off you. I’m 90% sure everyone is protected. I never dealt with [Perry] only his assistant. So the assistant was the enabler.”

The court documents also revealed that he asked Sangha on whether the ketamine stays in your system or “is it immediately flushed out.”

Dr Pepper, Bots, Cans

The people who allegedly exploited Perry used coded language for ketamine and called it “Dr Pepper”, “bots”, or “cans.”

Selling overpriced drugs, taking advantage of Perry’s mental condition and falsifying medical records to make the drugs given to him look legitimate by Dr Plasencia is what took Perry’s life.

Iwamasa is said to have administered more than 20 shots of ketamine and three on the day Perry died. Whereas ketamine is only administered by a physician. Authorities also found that weeks before Perry’s death, Dr Plasencia allegedly bought 10 vials of ketamine and intended to sell to Perry.

He also injected Perry with a large dose, two days later. This caused him to “freeze up” and spiked his blood pressure.

When I Die, I Want Helping Others To Be The First Thing That’s Mentioned

Perry had always been open about his drug addictions, struggles with alcohol and his depression. He said that his openness would help others who are also struggling and wanted to be remembered by his quote which also is on the homepage of the Mattew Perry Foundation that helps others struggling with the disease of addiction: “When I die, I want helping others to be the first thing that’s mentioned.”

Five arrests have been made in the case so far.

Nathan Crawford from the UK was just 9-years-old when his testicular tissue was frozen, before undergoing chemotherapy for his brain tumor.

About 16 years later, the cryopreserved immature testicular tissue was reintroduced into his body, which triggered sperm cell production and restored his fertility, according to researchers from the Vrije Universiteit Brussel.

“This is an important step in further scientific research to preserve the fertility of children with cancer or other blood diseases for the future. While the procedure is specifically designed to restore fertility, we cannot at this time guarantee that it will be successful or that patients can go on to have children. This treatment offers lots of perspectives for these young adults. They now have options that they did not have until recently,” said Dr Veerle Vloeberghs, part of the novel trial and staff member at Brussels IVF.

What Had Happened To Nathan

Nathan, now 27-years-old, had a type of tumor called a glioma, which develops from the glial cells that support the nerve cells of the brain, The Guardian reported. The tumor was so close to vital brain tissue that surgeons were unable to remove it without causing serious damage to important brain functions.

He underwent radiotherapy and chemotherapy to shrink his tumor, before which surgeons at the John Radcliffe hospital in Oxford in a keyhole surgery removed and froze a wedge of testicular tissue, with the aim that it is one day re-implanted into Nathan.

How Is The Testicular Tissue Preserved?

While Chemotherapy and radiation therapy are lifesaving they can destroy testicular stem cells, the precursors of sperm cells in boys who undergo radical treatments before starting puberty. As it can affect their fertility, preventively removing and freezing testicular tissue is an option pioneered by UZ Brussel.

In 2002, UZ Brussel became the first hospital worldwide to initiate a clinical fertility preservation program for young boys suffering from cancer or diseases of the blood, bone marrow or lymph nodes.

Since then, the hospital has frozen testicular tissue fragments of 141 boys.

The tissue is preserved in liquid nitrogen at -196°C.

Prepubescent boys do not yet produce sperm cells. The removed tissue contains stem cells that would normally produce sperm after starting puberty.

"While the procedure is specifically designed to restore fertility, we cannot at this time guarantee that it will be successful or that patients can go on to have children,” Dr Vloeberghs said.

How Was The Testicular tissue Implanted

The Guardian reported that in 2025, four tissue fragments were grafted back into the remaining testicle and four under the skin of the scrotum.

After a year inside the body, the grafts were removed and analysed in the laboratory. The results are published in a preprint paper, which is yet to be peer reviewed.

Two of the grafts from inside the testicle had produced mature sperm, which was collected and frozen.

Because the tissue fragments are not directly connected to the sperm duct, the researchers do not expect sperm cells to naturally find their way into the semen.

“This is a huge finding,” Prof Ellen Goossens, of the Vrije Universiteit Brussel, who led the trial was quoted as saying. “Many more people will have hope that they can have biological children. It’s great to see for the patients for whom we already have tissue banked.”

A new research paper published in the PNAS Journal triggered concerns over the potential risk of influenza D spilling over into humans.

Although primarily found in livestock such as cattle and swine, this virus has been increasingly studied due to evidence of exposure among agricultural workers.

A key concern raised was that the influenza D virus triggers a relatively weak early immune response in human respiratory cells.

However, to understand whether it is just a hype or a real concern, HealthandMe spoke to Dr. Rajeev Jayadevan, Ex-President of IMA Cochin and Convener of the Research Cell, Kerala.

“So far, this virus has not been a major cause of respiratory disease in man, unlike other types of Influenza viruses like H1N1 and H3N2 of the Influenza A family. It is true that studies have demonstrated antibodies against this virus among cattle farmers, which is consistent with its ability to infect species other than cattle,” Dr. Jayadevan said.

He noted that the virus may not be an “imminent threat” to humankind as feared.

“So far, the signals are that this virus remains primarily a cattle pathogen, which doesn’t pose an imminent threat to man, unlike other types of influenza viruses”.

What is the Influenza D Virus?

Influenza D is one of four types of influenza viruses and belongs to the Orthomyxoviridae family. Unlike the more familiar influenza A and B viruses that cause seasonal flu in humans, influenza D has primarily been detected in animals, particularly cattle and pigs.

According to the US CDC, the virus was first identified in 2011. It has since been found across multiple species, including livestock and wildlife, including camels, deer, giraffes, kangaroos, llamas, wallabies, and wildebeests.

It is not currently known to cause illness in humans, but has had a spill over in different animal species — more recently in poultry.

CDC’s January 2026 report stated that “influenza D has shown to have considerable potential for causing future human epidemics, but diagnostics and surveillance for the viruses are lacking”.

What Did The PNAS Study find?

Researchers investigated multiple influenza D virus isolates collected from livestock between 2011 and 2020 to assess their ability to infect human airway systems.

The paper demonstrated that the virus is capable of infecting human respiratory cells and was also adept at switching off the interferon-based ‘alarm systems’ of the cell.

This means that the virus may spread silently and efficiently, but without causing significant symptoms, Dr. Jayadevan said.

Importantly, the findings suggest that only small genetic changes might be needed for influenza D virus to achieve more sustained transmission in humans, although this has not yet been observed.

H5N1 Bird Flu: A More Deadly Threat

Dr. Jayadevan told HealthandMe that a bigger concern for humans besides the commonly circulating human Influenza A and B viruses is the avian influenza (bird flu) virus H5N1.

H5N1 spreads among birds and carries a very high death rate whenever it infects humans.

“Fortunately, this bird flu virus isn’t able to easily spread from person to person, but ongoing mutations could potentially change that,” the expert said.

US President Donald Trump’s visit to a dentist in Florida over the weekend has reignited discussions about his health.

While past presidents have opted for the White House's on-site clinic, Trump went for a local dentist instead, a choice he made previously in January.

Trump's Dentist Visit Triggers Concern

Concern for the health of the President, set to turn 80 next month, was further fueled by a social media post by Nancy Mace, representative for South Carolina, where she wrote, “Pray for President Trump.”

Her sudden post came after the news that Trump had left his Jupiter golf club in Florida for a dentist appointment.

The White House, in a press pool reported: "President Trump is going to a scheduled dental appointment at his local dentist in Florida", The NewsWeek reported.

Republican strategist Cheri Jacobus also wondered about the timing of the President's appointment and what "caused him to suddenly leave his golf course?" Jacobus also questioned the White House for hiding Trump's health status.

However, there has been no statement from Trump’s office, family, or verified government channels confirming any medical emergency or surgical procedure as of now.

Trump's Health Issues

It is not the first time that Trump has been the subject of numerous health-related scrutiny — ranging from his mental state to visible bruising around his hands.

While there remains no official medical update on the discoloration in Trump's hand, Dr. Amit Prakash Singh, Consultant - Internal Medicine at the CK Birla Hospital, Delhi, told HealthandMe that there are possible underlying causes that can result in hand discoloration. He noted that the condition may be due to:

• Bruising (bleeding under the skin)
• Low oxygen or poor circulation
• Swelling (fluid buildup in tissues)
• Infection or inflammation

Media reports also expressed concern over Trump’s swollen ankles, which were photographed again during his weekend trip to Florida.

On Saturday, Trump was photographed with his son, Donald Trump Jr. His swollen ankles visible in the photos are likely the result of chronic venous insufficiency (CVI), which he was diagnosed with last July.

"CVI damages those valves, causing blood to pool in your legs. This increases pressure in your leg veins and causes symptoms like swelling and ulcers," according to the Cleveland Clinic.

In January, Trump told the Wall Street Journal that he'd tried using compression socks to help treat the issue but stopped because he "didn't like them."

Trump has also made some unusual medical choices in the past. Most notable is his use of aspirin. Trump takes 325 milligrams of aspirin every day, according to the Daily Beast. That's four times the doctor-recommended dosage.

Trumps' Dipping Image Among Americans

Meanwhile, nearly 60 per cent of Americans are questioning whether or not Trump is healthy enough to serve in the Oval Office, according to a Washington Post-ABC News-Ipsos poll.

In addition to dissatisfaction over Trump’s leadership on the Iran war, economy, and inflation, a growing share of Americans are also questioning the President’s mental acuity for the position.

Nearly 6 in 10 say he does not have the mental sharpness, while 55 percent say he is not in good enough physical health to serve effectively.
