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

Friends Actor Matthew Perry

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.

Long COVID is a group of debilitating conditions that can persist for months or even years after infection with the SARS-CoV-2 virus, which causes COVID-19.

While scientists are still working to fully define the condition, one of the most common and disabling symptoms is brain fog—a cognitive impairment that can significantly affect people's personal and professional lives.

People with brain fog often report difficulty concentrating, multitasking, reading, remembering information, and speaking in full sentences. Fatigue frequently worsens these symptoms. Despite its widespread impact, there are currently no established diagnostic tests or approved treatments for long COVID-related cognitive impairment.

First Treatment For Brain Fog

A new clinical trial led by researchers at UCL now offers promising evidence that cognitive rehabilitation may provide lasting relief for these symptoms.

Published in JAMA Network Open, the study found that a 10-week cognitive rehabilitation program helped people with long COVID-related brain fog achieve meaningful improvements in returning to work, hobbies, and everyday activities.

The treatment consisted of weekly one-hour, one-to-one video sessions with a therapist who helped participants develop practical strategies to meet their personal rehabilitation goals. Most participants continued to benefit from the program for at least six months after treatment.

"As many as one in three people with COVID go on to develop long COVID, and cognitive difficulties are among the most common symptoms that can persist for months, disrupting day-to-day functioning and quality of life. People might find it hard to focus or hold on to their thoughts as they struggle with memory, attention and planning, often compounded by fatigue," said lead author Dr Martina Vanova, who completed the research at UCL before moving to Kingston University.

"In our study, we used well-established strategies of goal-oriented cognitive rehabilitation to help people develop ways to tackle the challenges that are most meaningful to them," Vanova added.

How Was The Study Conducted?

The study, funded by the National Institute for Health and Care Research (NIHR), included 78 participants in England who had experienced cognitive symptoms of long COVID for at least three months.

Half of the participants received the cognitive rehabilitation program, while the other half continued with standard NHS care, which varied by region.

Before treatment began, each participant completed an online goal-setting interview to identify three personal goals they wanted to achieve. Most goals focused on returning to work and improving job performance, while others involved everyday activities such as staying focused long enough to watch a full film or read a book.

Therapists then worked with participants to develop personalized strategies to help them achieve those goals.

What Did the Study Find?

Three months after completing treatment, 84% of participants who received cognitive rehabilitation reported a significant improvement in goal attainment on a 10-point scale, compared with 53% of those receiving standard care.

The benefits were sustained over time. After six months, 53% of participants in the rehabilitation group reported a substantial improvement—defined as an increase of four or more points on the 10-point goal scale—compared with just 15% of those in the control group.

Researchers also observed measurable improvements in executive function, including better cognitive flexibility and faster processing speed.

Researchers also noted that early findings from a separate analysis suggest the program is cost-effective.

"We have found a treatment that provides clinically meaningful and sustained benefit for people with cognitive long COVID symptoms," said Joint senior author Dr Aida Suarez-Gonzalez of the UCL Queen Square Institute of Neurology.

"As this program is based on established cognitive rehabilitation techniques that have been used for other conditions, we hope that it can be easily rolled out as a treatment option for people currently living with long COVID."

80 Years Of CDC: How America’s Premiere Health Institution Changed Under Donald Trump’s Administration

Updated Jul 2, 2026 | 09:00 PM IST

SummaryFrom vaccine policies to staff reduction, after 80 years, the U.S. Centers for Disease Control and Prevention looks completely different under Donald Trump’s regime.
80 Years Of CDC: How America’s Premiere Health Institution Changed Under Donald Trump’s Administration

For nearly eight decades, the U.S. Centers for Disease Control and Prevention (CDC) has been regarded as one of the world's leading public health institutions.

Established in 1946 to combat malaria, the public health agency has since evolved into a global authority and standard on infectious diseases, vaccinations, chronic illnesses, epidemics, emergency preparedness, health surveillance and much more.

However, the institute has undergone significant changes President Donald Trump returned to the White House in January 2025.

80 Years Of CDC

Since its inception in 1946, the CDC has led the response to numerous public health threats, including polio, HIV/AIDS, Ebola, Zika, H1N1 influenza, and the COVID-19 pandemic.

CDC scientists have spent decades shaping its long-standing vaccination programs and policies, disease tracking systems, and emergency responses during epidemics that have influenced public health policies and practices globally.

CDC Under Donald Trump’s Regime

As the institution completes eight decades, we take a look at how it has changed over time under Donald Trump’s administration. From changes in vaccination policies, reduction in workforce to a shuffle in leadership, CDC has undergone a tectonic shift.

While planning and preparedness for infectious disease has been a huge part of CDC's legacy, the current administration has increasingly focused on chronic diseases, nutrition, and environmental exposures.

Appointment of Robert F. Kennedy Jr. as HHS Secretary

One of the earliest and most controversial consequential decisions of the administration was the appointment of Robert F. Kennedy Jr. as Secretary of the U.S. Department of Health and Human Services (HHS).

Kennedy, who is a renowned anti-vaxxer, introduced different goals for federal public health, particularly on chronic disease prevention, environmental health, and greater scrutiny of long-standing vaccine policies.

Soon after the administration took office, HHS was significantly restructured, with plans to consolidate many public health functions under a newly created Administration for a Healthy America.

Largest Staff Reduction In The History Of CDC

In February 2025, more than 1,300 employees of Centers for Disease Control and Prevention lost their jobs. Workforce restructuring was carried out in multiple departments in the following months.

Departments like outbreak surveillance, violence prevention, antibiotic resistance surveillance, Freedom of Information Act requests, and laboratory leadership programs were either downsized or eliminated.

Public health experts widely critcised the move, warning that the reductions could hamper the country’s ability to detect and respond quickly to future outbreaks.

Changes In Vaccine Policy

One of the healthcare sections that saw perhaps the biggest change under Trump’s administration was vaccination.

In June 2025, HHS dismissed all 17 members of the CDC's Advisory Committee on Immunization Practices (ACIP), the independent panel tasked for recommending how vaccines are used in the country.

The committee was later recreated with new members. The move that drew criticism from several medical and scientific organisations. The administration revised several vaccine recommendations, particularly those relating to COVID-19, vaccination for healthy children and pregnant women.

The U.S. additionally withdrew its financial support for Gavi, the Vaccine Alliance. It also stopped hundreds of millions of dollars in federal funding for mRNA vaccine research, including projects involving COVID-19, influenza and RSV vaccines.

Changes In Gender-Related Healthcare Policies

Major changes were made in reproductive and gender-related healthcare policies. One of the most talked about was the Mexico City Policy, also known as the ‘global gag rule’. The move restricted U.S. funding for non-government organisations that provide abortion services.

Insurance coverage and funding for gender-affirming healthcare was withdrawn. Several LGBTQ+ references were removed from many federally supported health programs, which sparked widespread outrage.

Changes In Leadership

Susan Monarez was appointed as CDC Director in 2025. But her stint was short-lived after she was dismissed later that year. Reports stated that disagreements over vaccine recommendations led to the leadership dispute. Several senior CDC officials also resigned after Monarez’s exit.

Trump supporters support these changes as they believe they are a part of a long-overdue overhaul of an institution they believe had grown too bureaucratic and too reliant on established scientific principles.

However, many public health experts argue that the changes have affected scientific independence, disrupted long-standing public health programs, and altered the CDC's traditional role as a reliable evidence-driven body.

This 45-Minute Weight-Loss Procedure May Work Better Than Semaglutide Pills, Study Claims

Updated Jul 2, 2026 | 08:00 PM IST

SummaryResearchers from AIG Hospitals, Hyderabad, found that patients who underwent ESG lost significantly more weight than those taking oral semaglutide after six months, offering early benefits. However, by 12 months, the gap between the two treatments narrowed.

Weight-loss medications such as oral semaglutide have become increasingly popular for treating obesity. However, a new study suggests that a 45-minute, minimally invasive procedure called Endoscopic Sleeve Gastroplasty (ESG) may deliver greater short-term weight loss than oral semaglutide tablets.

Published in the Endoscopy journal, the study compared two established non-surgical obesity treatments—ESG and oral semaglutide 14 mg.

ESG Led to Greater Weight Loss at 6 Months

Researchers from AIG Hospitals, Hyderabad, found that patients who underwent ESG lost significantly more weight than those taking oral semaglutide after six months.

Patients treated with ESG achieved an average 12.72% total body weight loss, compared with 8.67% among those taking semaglutide. The difference remained significant even after adjusting for age, sex, BMI and diabetes.

"The most important message from this study is that obesity treatment has to be individualized. ESG appears to offer a stronger early push in weight loss, especially for patients who need a meaningful reduction in a short period," said Dr. Nitin Jagtap, Consultant Gastroenterologist at AIG Hospitals.

He added that ESG is not a shortcut but a structured intervention that helps patients reset eating habits and build sustainable lifestyle changes.

How Was the Study Conducted?

The retrospective study included 150 adults with obesity treated between January 2024 and April 2025. Of these, 50 underwent ESG, while 100 received oral semaglutide 14 mg once daily.

All participants also followed a calorie-deficient diet and moderate exercise plan, highlighting that both treatments work best alongside lifestyle modifications.

What Did the Study Find?

ESG also outperformed semaglutide in the number of patients achieving clinically meaningful weight loss.

  • 70% of ESG patients lost at least 10% of their body weight, compared with 43% in the semaglutide group.
  • 36% of ESG patients achieved 15% or more weight loss, versus just 7% of those taking semaglutide.

No major adverse events were reported in either group.

Notably, by 12 months, the gap between the two treatments had narrowed. Average weight loss was 11.92% in the ESG group and 10.91% in the semaglutide group, with no statistically significant difference.

The findings are particularly relevant for India, where obesity often occurs alongside diabetes, fatty liver disease and cardiovascular risk at lower BMI levels than in Western populations, the researchers said.

Researchers Urge Caution

The researchers noted that the findings should be interpreted carefully because this was a retrospective, single-centre study, not a randomized clinical trial.

They also stressed that the comparison was limited to oral semaglutide 14 mg and should not be extended to higher-dose injectable GLP-1 drugs or newer dual-incretin therapies, which may produce different results.

"Obesity care is entering a new phase where endoscopy, pharmacology, nutrition and lifestyle medicine must come together," said Dr. D. Nageshwar Reddy, Chairman of AIG Hospitals.

He emphasized that ESG and medications like semaglutide should be viewed as complementary options rather than competing therapies, with the shared goal of achieving and maintaining meaningful weight loss.

ESG vs Oral Semaglutide: How Do They Work?

Endoscopic Sleeve Gastroplasty (ESG) is a minimally invasive procedure performed through the mouth without external incisions. Using an endoscope and suturing device, doctors reduce the stomach's size by placing internal stitches, helping patients feel full sooner without surgically removing part of the stomach.

Oral semaglutide belongs to the GLP-1 receptor agonist class of drugs. It reduces appetite, increases feelings of fullness and helps lower calorie intake. Unlike ESG, it requires daily medication, long-term adherence and continued affordability.
