“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.

Union Minister of State (Independent Charge) for Science and Technology and Earth Sciences, along with responsibilities in the PMO, Personnel, Public Grievances, Pensions, Atomic Energy, and Space, Dr Jitendra Singh on Tuesday called for careful and evidence-led use of anti-obesity and weight-reduction medicines. He stressed that these drugs should be prescribed thoughtfully and not treated as routine or easy solutions.
Addressing the inaugural session of the Asia Oceania Conference on Obesity (AOCO), the minister said obesity is a complex, long-term condition that tends to recur and cannot be managed through isolated medical treatment alone. Instead, he said, it needs a wider response involving society at large.
At the same event, Dr Singh also launched the National Obesity Registry, describing it as an important step towards strengthening India’s obesity research framework. The initiative aims to support structured data collection, generate reliable evidence, and guide long-term policymaking in the area.
During the conference, Dr Jitendra Singh formally unveiled the AIAARO Obesity Registry, calling it a major move to strengthen India’s research ecosystem. The registry will focus on systematic data collection, long-term follow-up, and evidence-based policymaking. It is expected to help improve clinical understanding of obesity and support the development of national strategies for its management.
India’s National Obesity Registry (NOR), launched in December 2025, is designed to create a strong and reliable data base on obesity trends across the country. This data will support public health policies, research efforts, and targeted interventions to address the growing obesity burden. The initiative is particularly significant for India, given its unique challenges related to metabolic obesity and its strong links with non-communicable diseases.
While launching the registry, Dr Singh also highlighted the strong focus placed by Prime Minister Narendra Modi on tackling lifestyle-related illnesses. He noted that the Prime Minister has repeatedly spoken about obesity on national platforms, reflecting a clear shift towards preventive healthcare. This approach, he said, is supported by initiatives such as FIT India, Khelo India, and programmes that encourage small but lasting behavioural changes.
The minister warned against the increasing commercialisation of obesity treatment and the spread of misinformation in this space. Referring to a PIB release, he said unscientific claims and so-called quick solutions often mislead people and divert attention from treatments backed by medical evidence.
India has seen a growing use of injectable obesity treatments such as Wegovy and Poviztra, both based on semaglutide, and Yurpeak, which uses tirzepatide. These once-weekly injections work by mimicking gut hormones that help regulate appetite and are marketed by companies like Novo Nordisk and Eli Lilly. However, doctors caution that these drugs are not miracle solutions and must be combined with proper diet and physical activity. There are also concerns about their overuse at a time when obesity rates continue to rise.
According to the World Health Organisation, obesity was linked to 3.7 million deaths globally in 2024. If strong action is not taken, the number of people living with obesity is expected to double by 2030. Recently, the WHO released its first-ever guideline on the use of Glucagon-Like Peptide-1, or GLP-1, therapies for managing obesity as a chronic and relapsing condition.
“Obesity is a major global health challenge that WHO is committed to addressing by supporting countries and people worldwide to control it effectively and equitably. Our new guidance recognises that obesity is a chronic disease that can be treated with comprehensive and lifelong care,” said WHO Director-General Dr Tedros Adhanom Ghebreyesus.

A Phase 1 randomised clinical trial of a new Nipah virus vaccine, led by researchers in the US, is offering fresh hope for preventing this deadly infection. The study found that all three doses and vaccination schedules of the candidate vaccine, called HeV-sG-V, were safe and successfully triggered an immune response. These findings were published in the medical journal The Lancet.
The World Health Organization has identified Nipah virus as a high-priority pathogen because it can be fatal in up to 82 percent of cases and currently has no approved treatment or preventive vaccine. The virus is mostly seen in parts of Southeast Asia.
Nipah virus, or NiV, is mainly spread by fruit bats but can also pass through pigs and other animals. It can lead to serious illness and death, and there is currently no medicine or vaccine available to treat or prevent it. According to the Cleveland Clinic, the virus is most commonly reported in Asia, especially in Bangladesh and India.
The virus can spread when:
The most effective way to reduce the risk of Nipah virus infection is to avoid contact with sick animals, particularly bats and pigs, in regions where the virus is known to circulate. This also means avoiding foods that could be contaminated, such as raw date palm sap or partially eaten fruit. Since Nipah can spread from person to person through bodily fluids, extra caution is advised when interacting with infected individuals.
A Phase 1 randomised clinical trial of a new Nipah virus vaccine has raised hopes that prevention may soon be possible. The trial showed that the vaccine was safe and produced an immune response, according to findings published on December 13 in The Lancet.
“The induction of antibodies within one month of vaccination, along with the sustained response seen with two doses, suggests this vaccine candidate could be useful both during outbreaks and for preventive purposes,” said researchers from Cincinnati Children’s Hospital Medical Center, which led the study, as per NDTV,
Scientists from the Indian Council of Medical Research–National Institute of Virology in Uttar Pradesh described the results as a “milestone” in Nipah vaccine development in an accompanying editorial published in The Lancet. The Phase 1 trial involved 192 healthy volunteers between the ages of 18 and 49.
The study found that a single dose did not produce a strong enough immune response. However, two doses were effective, with the strongest antibody responses seen in participants who received two 100-microgram doses of HeV-sG-V given 28 days apart.
The most common side effect reported was mild to moderate pain at the injection site. No serious side effects, hospital admissions, or deaths were reported during the trial. In their editorial, ICMR-NIV experts noted that the vaccine should next be tested in a larger Phase 2 trial to better understand its safety profile and determine how much protection it can actually provide.

Flu A, or the new version of the flu virus called H3N2 is spreading quickly, the worst part is that fewer people are getting the flu shots. Doctors and scientists say that this year's influenza season could be tougher than the usual. Dr. Amanda Kravitz, a pediatrician at Weill Cornell Medicine in New York in an interview to CBS Mornings, said, "This flu season is no joke. We are seeing more cases than we would expect for this time of year. We are seeing influenza A, and within influenza A we are seeing a subtype or variant called H3N2."
Scientist Jesse Bloom, at the Fred Hutchinson Cancer Center who studies viral evolution said that "it is pretty likely to be an H3N2-dominated flu season. I don't see any reason to think that this is an unprecedentedly bad one, but current indicators are that it may be substantially more severe than the typical winter flu season," as reported by CBS News.

Not just the UK, but as per the journal of the British Medical Association, even the United Kingdom is suffering from an early and severe fly season, all thanks to the influenza A H3N2 called subclade K. Neil Maniar, director of the master of public health program at Northeastern University said, "The United Kingdom got hit pretty hard by this," as well as Europe and Australia. "I think that's a pretty good harbinger of what we are likely to see here. This is going to be a very difficult flu season."
Experts are pointing out that while the vaccine may not be a good match for the updated flu virus circulating, it is still the best line of defense. Flu vaccines have an efficacy rate of 40% to 60%, however, as per as early report by Eurosurveillance, the efficacy of the current vaccine rate was between 32% to 39% in adults, and 72% to 75% in children. However, it is still important to get the vaccine to avoid any severe illness from the flu virus, point out experts.
"If you haven’t done so, get (the vaccine)," Maniar pointed out. “Definitely get it as we go into the holidays, as we go into new year’s and the new school year." It takes about two weeks to build up a solid immune response, however, within several days of getting the vaccine, people start to develop some immunity.

Dr Helen Chu, a flu expert at the University of Washington told the CBS News that based on the UK and Japan data, there will be more cases of hospitalization by this flu. The flu activity is "starting everywhere right now" and would be overlapping with RSV, before the winter COVID-19 wave.
Trevor Bedford, who also studies viral evolution at the Fred Hutchinson Cancer Center, said H3N2 tends to evolve faster than other influenza strains. "I expect more H3 incidence than the typical year and poorer vaccine effectiveness," he said.
"Total season effectiveness is probably going to actually be much, much lower," Chu warned, because immunity fades over time.
However, despite the mismatch in the vaccine, experts stress the fact that the flu vaccine is still helping preventing severe illness, especially in children. They also help in preventing severe diseases, hospitalization and deaths.
