“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.

The UK's human papillomavirus (HPV) vaccination program, initiated in 2018, has achieved a remarkable milestone: no women aged 20 to 24 died from cervical cancer in England between 2020 and 2024, according to a study published in the journal The Lancet.

England introduced the HPV vaccine for girls in 2008 and expanded the program to boys in 2019. By 2024, vaccine coverage among women aged 20-24 had reached nearly 90 per cent.

Researchers found that there were no cervical cancer deaths in this age group during the five-year period, compared with an estimated 23 deaths that would have been expected based on historical trends.

The study also estimated that HPV vaccination has prevented approximately 200 cervical cancer deaths among young women in England since the program began.

"It's amazing news that no women aged between 20 and 24 died from cervical cancer in the whole of England between 2020 and 2024," said Peter Sasieni, Professor of Cancer Epidemiology at Queen Mary University of London.

"That remarkable fact is thanks to nearly 90% of Gen Z women having received the HPV vaccine through the school vaccination and catch-up programs," he added.

This marks the first time that zero cervical cancer deaths have been recorded in this age group and provides compelling evidence of the vaccine's life-saving impact.

Children Vaccinated At 12-13 Had Near-Zero Risk

The study found that girls vaccinated at ages 12-13 had an almost zero risk of dying from cervical cancer before the age of 30, highlighting the success of the school-based vaccination program.

While several countries have reported declines in cervical cancer rates following HPV vaccination campaigns, evidence linking vaccination programs directly to reductions in cervical cancer deaths has been limited.

"This is the first national-level evidence, albeit observational, linking high HPV vaccination coverage to a major reduction in cervical cancer deaths," the researchers noted.

How The Study Was Conducted

Researchers analyzed HPV vaccination rates and cervical cancer mortality data among women in England between 2001 and 2024.

In addition to recording zero cervical cancer deaths among women aged 20-24 between 2020 and 2024, the study found an 80 per cent reduction in cervical cancer deaths in the same age group between 2015 and 2019.

The findings underscore the importance of achieving high vaccination coverage against a disease that remains one of the leading causes of cancer-related deaths among younger women worldwide.

"We estimate that since its introduction, HPV vaccination has prevented nearly 200 young women from dying from cervical cancer in England," said Sasieni.

"But that's just the tip of the iceberg. As vaccinated generations grow older, we'll see many more lives saved from cervical cancer. It is incredible to think that a single jab can almost eliminate a particular type of cancer."

The human papillomavirus (HPV) is the most common viral infection worldwide, with more than 200 known types. While some types lead to benign skin warts, others are responsible for severe health threats, such as cervical, throat, anal, and penile cancers. The HPV vaccine provides strong protection against the most lethal strains, avoiding long-term health complications.

The HPV vaccine helps the immune system recognize and fight off high-risk strains of the virus before they cause harm. It protects against:

• Genital warts
• Cervical cancer
• Vaginal, vulvar, anal, and penile cancers
• Mouth, throat, head, and neck cancers linked to HPV.

Have you been popping omega-3 pills hoping to improve your memory or keep your brain sharp as you age? New research suggests they may not deliver the cognitive benefits many people expect.

A clinical trial, published in the journal eBioMedicine, found that omega-3 supplements did not improve memory, cognition, or brain health in older adults at risk of Alzheimer's disease.

Omega-3 fish oil and algae-based supplements have long been promoted as a way to protect against dementia and Alzheimer's disease. However, the new randomized, double-blind, placebo-controlled trial — considered the gold standard in medical research — found no evidence that these supplements slowed cognitive decline or protected the brain.

The study was led by researchers at the University of Southern California and included 365 adults aged 55 to 80 who rarely consumed fish, a natural source of omega-3 fatty acids.

"We all wish there was a silver bullet for preventing Alzheimer's, but our findings showed that fish oil supplements do not appear to protect brain health," said Hussein Naji Yassine, director of the USC Center for Personalized Brain Health and lead investigator of the study.

"While omega-3s play an important role in forming brain cell connections needed for cognition, our results do not support fish oil supplements as a preventive measure against Alzheimer's," he added.

How The Study Was Conducted?

Researchers recruited 365 adults who were considered at elevated risk for Alzheimer's disease. Nearly half (47 per cent) carried the APOE4 gene, the strongest known genetic risk factor for late-onset Alzheimer's.

Participants were randomly assigned to receive either a daily omega-3 supplement or a placebo.

The supplement contained 2,000 mg of docosahexaenoic acid (DHA), an omega-3 fatty acid essential for brain function.

The researchers first examined whether DHA from the supplements could reach the brain. By measuring DHA levels in cerebrospinal fluid — the liquid surrounding the brain and spinal cord — they found a 17 per cent increase after six months, confirming that the nutrient successfully reached its target.

The team then assessed memory and cognitive performance at the beginning of the study and again two years later.

Despite higher DHA levels in the brain, participants who received the supplements performed no better on memory and cognitive tests than those taking the placebo. Brain scans also revealed no difference in shrinkage of the hippocampus, a memory-related brain region that commonly deteriorates with aging and Alzheimer's disease.

What Works Instead? A Healthy Lifestyle

The researchers emphasized that maintaining overall health remains the most effective strategy for preserving brain function and reducing Alzheimer's risk.

"Staying healthy throughout life remains the most powerful tool we have for reducing Alzheimer's risk, including regular exercise, quality sleep, and a balanced diet," said Yassine.

He compared brain health to maintaining a vehicle.

"Living a healthy lifestyle is the brain's equivalent of getting regular car maintenance and high-quality oil changes. The brain is more likely to lose function if health issues elsewhere in the body go unaddressed, just as an engine eventually fails without proper maintenance."

What's Next?

Yassine and his colleagues are now investigating why omega-3 supplements can successfully reach the brain yet fail to produce measurable cognitive benefits.

The team is also exploring new therapies that could help the brain make better use of omega-3 fatty acids and potentially preserve cognitive function as people age.

A parliamentary committee in Canada has recommended that the country's assisted dying laws continue to exclude people whose sole underlying condition is a mental illness.

According to the committee's report, Canada's assisted dying framework should "indefinitely exclude" individuals whose only medical condition is a mental illness.

Canada first passed its assisted dying legislation, known as Bill C-14, in 2016, marking a significant development in healthcare and personal autonomy.

Officially known as Medical Assistance in Dying (MAID), the law initially applied only to adults who were terminally ill. However, eligibility for MAID has remained one of the country's most contentious healthcare issues over the past decade, with plans to expand access delayed twice.

Committee Recommends Permanent Exclusion

The 98-page report by the joint House and Senate committee on Medical Assistance in Dying contains a single recommendation: that Canada "indefinitely exclude persons whose sole underlying medical condition is a mental illness from eligibility for medical assistance in dying", according to the BBC.

The report noted a "divergence of perspectives" on the issue and highlighted concerns raised during testimony about the "pressing need for increased and more equitable access to adequate mental health services".

However, some committee members disagreed with the findings and published a dissenting report, arguing that the process was "fundamentally flawed", "biased", and favored testimony from those opposed to expanding MAID. Canada's government must respond to the report by July 11.

What Does Canada's MAID Law Say?

When MAID was introduced in 2016, it was available only to adults who were terminally ill.

The eligibility criteria were strict. Individuals had to be suffering from a "serious and incurable illness", be in an "advanced state of irreversible decline", experience "intolerable suffering", and have a natural death that was "reasonably foreseeable".

This legal pathway became known as Track 1. Modelled on end-of-life care, it primarily served people with terminal cancer or other severe illnesses who wanted greater control over the dying process. Track 1 remains a relatively swift procedure, with some patients receiving MAID within a day of applying.

Expansion Beyond Terminal Illness

However, many Canadians living with severe non-terminal conditions argued that they were excluded from the law. These included people with degenerative diseases, chronic pain, or spinal injuries who experienced significant suffering but were not nearing death. Many requested MAID but were routinely denied.

In 2019, the country introduced Bill C-7 in 2021, creating Track 2 and extending MAID eligibility to people with serious, incurable conditions causing enduring suffering even when death was not foreseeable.

Track 2 includes additional safeguards, including a 90-day assessment period, evaluation by two independent clinicians, and consultation with specialists when necessary.

Ongoing Debate Over Mental Illness Eligibility

Despite its stricter safeguards and ethical complexities, Track 2 MAID has steadily gained use. In 2023, there were 622 deaths under Track 2 compared with 14,721 under Track 1.

Supporters view Track 2 as a compassionate option for people living with severe, non-terminal suffering, while critics argue it risks exposing vulnerable populations to premature death.

In 2023, Canada first delayed eligibility for MAID for people whose sole condition was a mental illness by one year, citing concerns that the healthcare system was not ready for the expansion. The government later delayed implementation again until March 17, 2027.

Along with the second delay, the government recommended that a parliamentary committee undertake a comprehensive review of the proposal.

MAID Accounts For About 5% of Deaths in Canada

According to the latest available figures from 2024, MAID accounts for around 5 per cent of all deaths in Canada. About 96 per cent of MAID cases involved people whose deaths were reasonably foreseeable, most of them terminal cancer patients.

The remaining 4 per cent involved patients whose deaths were not imminent but who had a "grievous and irremediable medical condition".
