“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.
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.”
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.
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.
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.”
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.
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.

One of the most effective ways to prevent rabies deaths could be by vaccinating dogs rather than just people before they are bitten. A new study published in The Lancet Regional Health – Southeast Asia modelled different strategies in Kerala for eradicating human rabies deaths between 2026 and 2035.
The study found that mass vaccination of dogs could bring the annual rabies deaths among people in Kerala close to zero within about three years even if 70% of the dog population were vaccinated.
On the other hand, vaccinating children before exposure to rabies was projected to prevent relatively few additional deaths at substantially higher cost.
India carries one of the worst largest rabies burdens. That's why the study could point towards a feasible and practical solution to eradicate the deadly infection.
Most human rabies deaths in India are linked to bites from infected dogs. This means that the disease can be tackled at its source by reducing transmission among dogs.
India records an estimated 9.1 million animal bites every year, with more than three-quarters caused by dogs. A 2024 estimate from the Indian Council of Medical Research's National Institute of Epidemiology estimates India's annual human rabies deaths to be about 5,726, which is an alarming public health issue.
The study puts emphasis on the fact that vaccinating a person after a bite protects that individual, whereas, vaccinating dogs reduces the probability that an infected dog will transmit rabies to many people in the first place.
Researchers from the University of Glasgow, Kerala's health and animal-husbandry departments, Kerala University of Health Sciences and the London School of Economics and Political Science used mathematical modelling to compare different strategies to combat rabies in Kerala.
One strategy was routine pre-exposure prophylaxis (PrEP) for children. Another focused on mass dog vaccination, while the model also considered improvements to post-exposure prophylaxis (PEP), the treatment given after a potentially rabid bite.
The researchers found that adding routine childhood PrEP provided minimal additional protection, preventing fewer than 10 deaths on average over a decade, while costing considerably more than strategies focused on controlling rabies transmission among dogs.
The model estimated that achieving 70% vaccination coverage among dogs could reduce annual human rabies deaths in Kerala to near zero within approximately three years.

One of the study's striking findings was about the size of Kerala's stray-dog population. The researchers' modelling suggested that the state's actual stray-dog population could be around five times higher than official census estimates.
If vaccination programmes are based on an underestimated dog population, authorities could believe they have reached adequate coverage while a large proportion of dogs remain unvaccinated. That creates what epidemiologists call an immunity gap, allowing rabies transmission to continue.
Additionally, dog vaccination does not make human post-exposure treatment unnecessary. If a person is bitten or scratched by an animal that could have rabies, the wound should be washed thoroughly with soap and running water and medical care should be sought immediately.
Depending on the exposure, PEP can include rabies vaccine and rabies immunoglobulin (RIG). This is particularly important because rabies becomes extremely difficult to treat once symptoms begin.
The study also found that improving timely access to PEP could prevent more deaths than expanding routine pre-exposure vaccination of children.

The death of Lady Joan Branson, wife of billionaire entrepreneur Sir Richard Branson, has highlighted the risk of a blood clot after fractures that travels to the lungs.
Lady Branson, 80, died at Lister Hospital in London in November 2025 after being admitted following a fall at her home on Necker Island. An inquest heard that she had developed a deep vein thrombosis (DVT) and subsequently suffered a massive pulmonary embolism (PE).
The coroner, Professor Fiona Wilcox, concluded that her death could probably have been prevented if anti-clotting treatment had been given earlier. She said: “If this lady had been given [anti-clotting medication] early on ... her death, on the balance of probability, would have been prevented.”
What exactly happens after a fracture that can make a blood clot so dangerous?
A fracture can trigger several conditions that encourage the development of venous thromboembolism (VTE), the collective term for DVT and PE.
First, injury itself activates the body's clotting system. The body naturally increases clot formation after tissue damage to prevent bleeding.
Second, a person with a fracture may become significantly less mobile. When the leg muscles are not moving normally, the muscle pump that helps push blood through the veins becomes less effective. Blood can therefore pool in the deep veins, particularly in the legs. Hospitalisation, surgery, older age, previous blood clots and certain medical conditions can add further risk.
A clot that remains in a leg vein can cause swelling and pain. But when part of it breaks and gets away, it can travel through the bloodstream to the lungs, leading to a pulmonary embolism.

A clot forming in a deep vein, usually in the leg, can detach and travel through the veins into the right side of the heart. From there, it can enter the pulmonary arteries, which carry blood to the lungs.
If the clot is large enough, it can obstruct blood flow through the lungs and suddenly increase pressure on the right side of the heart.
A large or massive PE can therefore cause severe breathlessness, low blood pressure, cardiac arrest and sudden death.
This is why PE can sometimes appear dramatically, even when the original DVT produced few obvious symptoms.
According to the inquest, Lady Branson had a history of blood clots dating back to 2010, and doctors heard evidence that she had previously used anti-clotting injections.
However, she was not given enoxaparin, a low-molecular-weight heparin commonly used to prevent or treat harmful blood clots, during her hospital stay.
One doctor, Dr Inaki Bovill, told the inquest that a venous thromboembolism risk assessment should have been carried out and that the medication should have been prescribed. He said: “It is to my great regret that I did not.”
Another doctor, Dr George Adams, a consultant haematologist at Imperial College London, told the inquest that earlier anticoagulation would have made cardiac arrest less likely in her particular case.
Lady Branson's daughter, Dr Holly Branson, disputed the suggestion that her mother had refused the injections because of previous pain or bruising. She told the inquest that this was “not consistent with my knowledge of her usual practice or attitude.”

The US Food and Drug Administration (FDA) is investigating an outbreak of Salmonella Bovismorbificans infections in multiple states. According to reports, the at least infection cases are being linked to recalled broccoli sprouts across four states, including two hospitalisations. The outbreak hasn't resulted in any casualties yet.
The outbreak has been linked to broccoli sprouts grown by Evergreen Fresh Sprouts, LLC, based in Moyie Springs, Idaho. The FDA and the US Centers for Disease Control and Prevention (CDC) are investigating the outbreak with state and local health authorities.
The FDA has issued a clear warning: “Do not eat, serve, or sell recalled broccoli sprouts grown by Evergreen Fresh Sprouts, LLC.”

According to the FDA, illnesses began between July 7 and August 26, 2026. Out of the 19 infected people who were interviewed by investigators, all 19 reported eating sprouts, while 17 specifically reported eating broccoli sprouts. That epidemiological pattern helped investigators identify sprouts as the likely driver of the infection.
Traceback investigations by the FDA and state partners then identified Evergreen Fresh Sprouts as the common grower of broccoli sprouts eaten by patients before they became sick.
On September 4, the company initiated a recall after Montana state officials found Salmonella in a sample of its broccoli sprout. Whole-genome sequencing showed that the Salmonella found in the product was the same strain causing illnesses in the outbreak.
The recalled products were sold in plastic bags or plastic clamshell containers and have expiration dates of September 7, 9, 11, 14 or 16, 2026.
Distribution has been confirmed in Idaho, Montana and Washington, although the FDA said the products may have reached additional states. The 22 cases are from Idaho, Montana, Utah and Washington.

Salmonella is a group of bacteria that can cause salmonellosis, a gastrointestinal infection usually acquired by consuming contaminated food or water.
Symptoms typically begin 12 to 72 hours after exposure and can include diarrhoea, fever and abdominal cramps. Most people recover within four to seven days without specific treatment, but some infections can become severe.
Young children, older adults and people with weakened immune systems are at greater risk of serious complications from the infection. In severe cases, Salmonella can cause dehydration or allow the bacteria to enter the bloodstream, potentially leading to invasive infection and complications affecting other organs.
Sprouts are grown in warm, moist conditions, which help seeds germinate but can also provide favourable conditions for bacterial growth.
The seeds themselves can become contaminated before sprouting. Once bacteria are present, the warm and humid environment used to produce sprouts can allow them to multiply. Since sprouts are often eaten raw, there may be no cooking step to eliminate the bacteria.
The current FDA investigation involves broccoli sprouts, and it is separate from another ongoing US investigation involving Salmonella and E. coli infections linked to alfalfa sprouts.
Consumers, restaurants and retailers should not eat, sell or serve the recalled Evergreen Fresh Sprouts broccoli sprouts.
The FDA also advises people who purchased or received the recalled product to carefully clean and sanitise surfaces and containers that may have come into contact with the sprouts. This is important because Salmonella can spread through cross-contamination.
Anyone who develops symptoms resembling Salmonella infection after eating the recalled sprouts should contact a healthcare provider.
