“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.

Climate activist and education reformer Sonam Wangchuk's indefinite hunger strike has entered a critical stage. After 20 days of without food, Wangchuk's condition worsened significantly. The spectacle drew nationwide attention as concerns over his deteriorating health continue to grow.

The protest, which began on June 28 at Delhi's Jantar Mantar, is aimed at demanding accountability over alleged irregularities in national entrance examinations like NEET and broader education reforms.

Wangchuk has experienced substantial weight loss ever since his hunger strike started. Doctors also warned that prolonged fasting could lead to serious complications, including organ involvement.

Sonam Wangchuk's Hospitalisation & 'Chalo Sansad' March

On July 18, Delhi Police shifted Sonam Wangchuk from the protest site to Safdarjung Hospital following medical advice and court-directed health monitoring. The move sparked controversy, with supporters alleging that he was moved to the hospital against his wishes.

According to the hospital, he’s receiving the necessary medical care, and his vital parameters remain stable.

“Sonam Wangchuk is being given the required medical intervention at VMMC & Safdarjung Hospital. His vital parameters are stable at present; however, his blood parameters remain marginally altered, and considering the physiological stress and systemic effects of prolonged fasting, he requires continuous medical care under the close observation of a multidisciplinary team of experts", the hospital's spokesperson said.

Despite being hospitalised, Wangchuk has remained firm on continuing his fast. In a handwritten note that was shared on his official X handle, he urged supporters to participate in the planned "Chalo Sansad" march on July 20.

When Does Hunger Strike Become Medically Concerning?

With Wangchuk's health continuing to deteriorate, his protest has renewed public interest in the medical dangers of prolonged hunger strikes.

The deterioration of one's health after a period of prolonged fasting is a medical emergency but it is highly variable.

Dr M Wali, Principal Director, Internal Medicine, Pacific One Health, says, "The timing of health deterioration becoming a medical emergency varies on various factors. It depends on age, existing health parameters before fasting, hydration, medications, environmental conditions and most important whether the person is taking only water or electrolytes. There is no fixed timeline for vitals to deteriorate."

24-72 Hours

In the first three days, the doctor says that the body suffers from spells of hunger, dizziness, and mild drop in blood pressure.

3 to 9 Days

During this period, fluctuations in blood sugar can start. The expert says that during this time, the body relies heavily on stored fats. Weight loss, low blood pressure, slow pulse, dehydration, and electrolytes imbalance start happening too.

10-14 days

Experts say that this is the critical period when serious complications can arise, especially like kidney injury, heart rhythm abnormalities, confusion, and collapse.

According to Dr Anshu Rohtagi, Sr Consultant at Department of Neurology, Sir Ganga Ram Hospital, "After sustained and prolonged complete fasting of couple of weeks, the risk of permanent organ damage and death increases manifold although survival depends on hydration and status of nutrition. Someone refusing both food and water can deteriorate much faster - sometimes in a few days also."

Another expert says that during this time, certain critical symptoms are evaluated that could cause serious complications.

According to Dr Niraj Tyagi, renowned critical care specialist, "The visiting medical team looks for signs that generally prompt urgent medical evacuations. Some of them are loss of consciousness or inability to stay awake, confusion or delirium, chest pain, abnormal heart rhythm, very low blood pressure causing fainting or shock, persistent low blood pressure, severe dehydration, little or no urine output, dangerous imbalance of electrolytes and kidney or other organs injury."

According to human rights experts, "Whether someone can be shifted to medical facility or treated against their wishes depends on local laws, court orders, and, most importantly, whether the person is in sound mental health to take informed decisions."

Treatment Plan

Dr. Wali explains how the treatment course looks like for someone who has been without food for weeks.

He says, "Once shifted to medical facility, treatment depends on the patient's condition and may include careful rehydration, correction of electrolytes imbalance, continuous cardiac and kidney monitoring, nutritional rehabilitation. Doctors usually monitor potassium, magnesium, and glucose closely during re-feeding."

He adds, "It is important to note that even after recovery, the person may remain medically vulnerable even if they feel well."

KRAS-Targeted Vaccine Shows Promise In Fighting Pancreatic Cancer, Triggers Strong Immune Response In Early Trial

Updated Jul 19, 2026 | 01:30 PM IST

SummaryA new vaccine trial conducted on humans for pancreatic cancer, one of the deadliest malignancies in the world, showed immense potential.
KRAS-Targeted Vaccine Shows Promise In Fighting Pancreatic Cancer, Triggers Strong Immune Response In Early Trial

A new experimental vaccine targeting one of pancreatic cancer's most common genetic mutations has shown encouraging results in an early-stage clinical trial.

Strong immune responses in most participants were observed, sparking fresh hope against one of the world's deadliest cancers.

About The Study

The Phase I study, published in Cancer Discovery, examined an investigational mutant KRAS-targeted vaccine (mKRAS-VAX) in patients who had undergone surgery for pancreatic ductal adenocarcinoma (PDAC), the most common form of pancreatic cancer.

The trial enrolled 12 patients with resected KRAS-mutant pancreatic cancer who received the vaccine alongside two immune checkpoint inhibitors, nivolumab and ipilimumab, after completing standard treatment.

Researchers observed vaccine-induced T-cell responses in 91.7% of patients, with immune cells remaining detectable for up to two years in some participants.

Importantly, patients who mounted stronger immune responses also appeared to remain disease-free for longer, although the study was not designed to prove that the vaccine directly improves survival.

Milestone Results Show Strong Immune Response

According to the researchers, pancreatic cancer has always been difficult to treat because it suppresses immune responses.

"The significant increase in vaccine-generated T-cell responses demonstrates that the immune system can be trained to recognize KRAS-mutant pancreatic cancer," the researchers said, noting that higher T-cell responses were associated with longer disease-free survival.

The researchers said that these findings support continued evaluation of KRAS-targeted vaccination strategies in larger clinical trials.

Parallel Research Shows Potential Too

The promising study follows another recently published Phase I trial in Cancer Discovery that tested a KRAS-targeted vaccine in individuals at high risk of developing pancreatic cancer.

That study found the vaccine safely stimulated KRAS-specific T-cell responses in about 90% of participants, suggesting such vaccines may eventually help prevent pancreatic cancer in selected high-risk groups.

Dr. Neeha Zaidi, associate professor of oncology at Johns Hopkins University and one of the corresponding authors of the prevention study, said, "Individuals at high risk due to hereditary predisposition or to the presence of a concerning pancreatic lesion detected on imaging usually undergo surveillance to monitor for changes over time."

She noted that surgery remains the standard treatment when cancer or high-risk lesions are detected, but recurrence remains common, highlighting the need for preventive strategies.

Elizabeth Jaffee, another author, said, "The goal of this study was to test the safety of the vaccine and induction of durable immune responses."

She added that the clinical trial was built on existing evidence showing KRAS-targeted vaccination could prevent progression of early precancerous lesions in animal .

Importance Of KRAS

KRAS is one of the most frequently mutated cancer-driving genes in pancreatic cancer, with mutations present in roughly 90% of pancreatic ductal adenocarcinomas. These mutations continuously prompt cancer cells to grow and divide.

However, scientists have spent decades trying to develop therapies capable of effectively targeting the protein.

Rather than attacking the cancer directly, the new vaccine teaches the immune system to recognize mutated KRAS proteins as abnormal and launch T-cell attacks against cancer cells.

Pancreatic cancer remains one of the most aggressive cancers worldwide because symptoms often appear only after the disease has spread beyond the pancreas.

While experts caution that the current findings come from an early-stage study, they say the results provide promising evidence that cancer vaccines can successfully activate the immune system against pancreatic tumors.

The Ludhiana health department has increased surveillance and prevention efforts after a bunch of new cases of malaria and dengue were reported in the district.

Health officials have stepped up inspections, awareness campaigns, and anti-larval operations, urging residents to eliminate stagnant water and seek medical attention at the first sign of fever.

According to recent reports, extensive door-to-door inspections are being carried out across residential areas, schools, and public spaces to identify mosquito breeding sites.

During these inspections, dengue mosquito larvae were found in several homes, prompting authorities to issue notices to property owners and instruct them to immediately remove stagnant water.

The department said these inspections are part of an ongoing strategy to reduce mosquito breeding before cases increase further during peak monsoon season.

Proactive Strategy To Prevent Increase In Infections

The move comes after Ludhiana experienced a difficult mosquito-borne disease season last year. Official data showed the district recorded 128 malaria cases, including one death, and 538 dengue cases with one fatality, making early intervention a priority this year.

Health authorities say that increasing temperatures combined with intermittent rainfall have created favourable conditions for mosquitoes to multiply rapidly, making community participation essential in preventing another surge.

Officials are stressing that dengue and malaria are transmitted by different mosquitoes and require slightly different prevention strategies.

Dengue is spread by the Aedes mosquito, which breeds in clean, stagnant water found in coolers, flower pots, buckets, discarded tyres, and rooftop water tanks. These mosquitoes are most active during the daytime.

Malaria, on the other hand, is transmitted by Anopheles mosquitoes, which usually bite from dusk until dawn.

Eliminating breeding sites remains the most effective way to reduce the spread of both diseases.

How To Protect Yourself In Monsoon?

Doctors advise residents to watch for symptoms such as high fever, severe headache, body aches, joint pain, chills, nausea, vomiting, excessive fatigue, or skin rashes. Anyone experiencing persistent fever should avoid self-medication and seek medical care promptly.

Early diagnosis helps prevent complications, particularly in severe dengue cases where warning signs such as abdominal pain, persistent vomiting, bleeding gums, or difficulty breathing require immediate hospitalization.

Health experts recommend practising a combination of personal protection and environmental control:

  • Empty and scrub water coolers, flower pots, buckets, bird baths, and other water containers at least once every week.
  • Keep overhead tanks, drums, and storage containers tightly covered.
  • Remove discarded tyres, plastic containers, coconut shells, and other objects that can collect rainwater.
  • Wear full-sleeved clothing, especially during peak mosquito activity.
  • Use mosquito repellents, coils, vaporizers, or insecticide-treated bed nets where appropriate.
  • Install window and door screens to reduce mosquito entry.
  • Cooperate with municipal fogging and anti-larval spraying teams when they visit your locality.

Public health officials say that preventing mosquito breeding at the household level remains the strongest defence against dengue and malaria. While health officials and their teams continue surveillance for containment, they emphasize that success depends on active community participation in keeping homes and neighbourhoods free of stagnant water.
