“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.

The popularity of GLP-1 weight-loss medications in the United States has reached its highest level yet. A new survey shows that nearly one in 10 American adults now takes the drugs to lose weight. At the same time, the country's obesity rate shows a steady decline. Experts say the survey does not prove that one trend is directly causing the other.
GLP-1 drugs, including medications such as semaglutide and tirzepatide, were originally developed to treat type 2 diabetes but have become increasingly popular for managing obesity after studies showed they could help people lose significant amounts of weight.
According to Gallup's latest National Health and Well-Being Index, 11% of U.S. adults currently use a GLP-1 medication for weight loss. In 2024, this number was just 3%.
The survey also said that 15% of adults have tried a GLP-1 medication at some point, compared to the 6% from two years ago.
The survey also found that 91% of Americans have heard of GLP-1 weight-loss drugs, up from 80% in 2024. The growing visibility of the medication reflects widespread media coverage, celebrity endorsements, and broader acceptance by patients and healthcare providers.

The Gallup report also found that the adult obesity rate in the US has fallen to 36.4% in 2026, down from a record 39.9% in 2022. The decline follows a similar trend seen last year, when obesity rates also dropped after years of steady increases.
Researchers noted that the decrease in obesity has occurred alongside the rapid rise in GLP-1 use. However, they said that the findings show an association rather than proof that the medications are responsible for the decline in obesity. Other factors, including lifestyle changes, healthcare access, fitness consciousness, and others may also be contributing.
Despite the decline in obesity, the percentage of Americans who have diabetes has remained relatively stable at around 13.5% since 2023, according to Gallup.
Researchers said this is not unexpected because diabetes is a lifelong condition. Even if people lose weight or improve their blood sugar control, they typically continue to be diabetic once diagnosed.
This is another move that will add to the popularity of GLP-1 drugs in the US. From July 1, people in the US will be able to access GLP-1 drugs for weight loss through a new pilot program, offered by the federal health insurance program Medicare. Slated to be operational for 18 months, the program will last till the end of 2027.
Until now, Medicare covered GLP-1 medications like Ozempic only for certain conditions like diabetes, but not for weight loss. The initiative aims to make these high-cost weight-loss medications more accessible to eligible candidates.
Eligible beneficiaries will be able to access the following GLP-1 weight-loss medications:
The medications will be covered only when prescribed for weight management and when beneficiaries meet the program's medical eligibility criteria.

After nearly two months, Uganda has announced that it has successfully contained its latest Ebola outbreak. Authorities say that prompt and aggressive surveillance, rapid treatment, contact tracing, and active cross-border coordination helped stop the spread. The government has now sought the removal of international travel restrictions that were put in place imposed during the outbreak.
The Ugandan Ministry of Health recently said all confirmed Ebola patients have either recovered or completed treatment, while every identified contact has been traced and monitored.
Diana Atwine, Permanent Secretary at the Ministry of Health, said on Sunday in a post on X that the outbreak had been contained. The Xinhua news agency reported that they treated of all imported confirmed cases and cared for those infected. They have also traced and quarantined the contacts.
Atwine also said a large team of medical personnel, two mobile laboratories and logistical support from Uganda were on their way to Congo to support the country's Ebola response.
The Ministry has also implemented preventive measures to curb the spread of the disease from eastern Congo, the epicentre of the ongoing outbreak, Atwine said. It included strengthening screening and preventive measures along the border with the DRC where a much larger Ebola outbreak continues to remain a global concern.
According to the latest figures, the country recorded 20 confirmed Ebola cases, including two deaths. 16 people have recovered from the disease.
The last confirmed infection was reported on June 21. The Health Ministry said that no new cases have been detected and reported since then. Most infections in Uganda were linked to travel from the DRC, while a only a few resulted from local transmission.
Officials argue that the outbreak has been effectively controlled through rapid isolation of patients, extensive contact tracing, quarantine of exposed individuals and supportive medical care.
She added that Uganda had begun urging countries that imposed Ebola-related travel restrictions to lift the measures.

In Congo, the situation is still grim. The capital of Ituri province remains at the heart of the Ebola outbreak. According to latest data, the country has recorded at least 1,561 confirmed cases, including 506 deaths and 254 people recovered. More than 10,000 contacts are being monitored.
Dr. Anne Ancia, WHO’s representative to the DRC said, “True scale has not yet been fully established. We would like to say it is stabilising, but frankly, we cannot say it yet.”
Amid the challenges, a few encouraging developments include the progress made on testing after daily capacity was increased from 30 tests in Kinshasa to more than 2,000 as 10 decentralised laboratories were established in the affected provinces on priority.
Another piece of good news is the start of a clinical trial on July 2, which can help identify and narrow down treatment options for Ebola, as currently there is no approved, proven path of treatment and cure for the Bundibugyo strain.
The trial will examine two promising therapies - a monoclonal antibody, MBP134, and the antiviral remdesivir.
The Bundibugyo virus was first identified in Uganda in 2007 and has caused only a few outbreaks since then. As infections have been relatively uncommon compared to the Zaire strain, researchers have had limited opportunities to develop vaccines, treatments and diagnostic tests.
Due to this, healthcare workers have been compelled to rely primarily on rapid isolation of patients, intensive supportive care, contact tracing, and strict infection prevention measures to slow transmission.
Currently, Eastern DRC is the hotspot for the Bundibugyo Ebola outbreak, where conflict, population displacement, skepticism, and insecurity have made it difficult for health workers to reach affected locations.

A team of US scientists has developed a new HIV vaccine that trains the immune system to overcome the virus's defenses, producing the strongest HIV-fighting antibody response ever reported in non-human primates.
The vaccine, developed by researchers from La Jolla Institute for Immunology (LJI), Scripps Research, and IAVI, is the first to generate a high number of broadly neutralizing antibodies against HIV in primates. Human trials have now begun.
“This feels like a huge success,” said LJI Professor and Chief Scientific Officer Shane Crotty.
“We constructed a successful vaccine from the ground up, which required a deep understanding of the immune system.” The findings are published in the journal Nature.
The vaccine is designed to guide the body's B cells—the immune cells responsible for making antibodies. Normally, B cells begin in a naïve state and gradually mature after encountering a virus. As they mature, they continuously refine the antibodies they produce, improving their ability to recognize and neutralize the virus.
Instead of waiting for this process to happen naturally, the new vaccine directs B cells through each stage of development.

The approach includes:
“This series of vaccinations will guide, or ‘walk’, a B cell from its naive state to its broadly neutralizing state,” said LJI Instructor Patrick Madden.
The scientists called this strategy germline targeting because it targets B cells before they begin their normal maturation process.
To evaluate the vaccine, researchers tested it in rhesus macaques. The results showed:
“We succeeded in taking ultra-rare antibody responses and turning them into common responses by the end of the vaccination process,” Crotty said.
The researchers did not test whether the antibodies could completely prevent HIV infection. However, finding these antibodies circulating in the bloodstream suggests they could potentially recognize and block the virus.

The researchers are now working to improve the vaccine further, including refining the booster schedule to increase the number of individuals who develop broadly neutralizing antibodies.
“It was incredible to get those results, but of course we'd like to see a response in 100 percent of the animals,” Madden said.
According to the researchers, the antibodies produced in the vaccinated animals closely matched the broadly neutralizing antibodies seen in the rare people who naturally develop them.
“We believe this vaccine approach is even more likely to succeed in humans, because of the immunogenetics,” Crotty said.
According to the World Health Organization, globally, 40.8 million [37.0–45.6 million] people were living with HIV at the end of 2024. Out of these, 1.3 million individuals newly acquired the virus, and 630,000 people died from AIDS-related illnesses.
To date, there is no vaccine available that will prevent HIV infection. Developing an HIV vaccine has remained one of the biggest challenges in medicine because the virus is exceptionally good at evading the immune system.
“The worldwide diversity of HIV mutations is extraordinary. Even the diversity within one individual person living with HIV is dramatic,” Madden said.
