An experimental treatment happens to be the solution to delay Alzheimer's symptoms in some people. These people are the ones who are genetically destined to get the disease in their 40s or 50s. These new findings form ongoing research has now been caught up in Trump administration funding delas. The early results of the study has been published on Wednesday and the participants too are worried that politics could cut their access to a possible lifeline.

One of the participants had said, "It is still a study but it has given me an extension to my life that I never banked on having." The participant is named Jake Henrichs, form New York City, who is 50 years old. He is one of them to be treated in that study for more than a decade now and has remained symptom-free despite inheriting an Alzheimer's-causing gene that had killed his father and brother around the same age.

Slowing Down The Symptoms

Two drugs which can modestly slow down early-stage Alzheimer's are sold in the United States. These drugs clear the brain of one of its hallmarks, a sticky gunk-like part called the amyloid. However, there have not been any hints that removing amyloid far earlier, way many years before the first symptoms appear, may postpone the disease.

How Was The Research Conducted?

The research is led by Washington University in St Louis, which involved families that passed down rare gene mutation as participants. This meant it was almost guaranteed that they will develop symptoms at the same age their affected relatives did.

The new findings is based on a subset of 22 participants who received amyloid-removing drugs the longest, on average eight years. Long-term amyloid removal cut in half their risk of symptom onset. The study is published in the journal Lancet Neurology.

Washington University's Dr Randall Bateman, who directs the Dominantly Inherited Alzheimer's Network of studies involving families with these rare genes says, "What we want to determine over the next five years is how strong is the protection. Will they ever get the symptoms of Alzheimer’s disease if we keep treating them?”

The researchers before though did not know what exactly caused Alzheimer's which affects nearly 7 million Americans, most of them in their later life. However, it is clear that these silent changes occur in the brain at least two decades before the first symptom shows up. The big contributor. At some point amyloid buildup can trigger a protein named tau that then starts to kill neurons, which can lead to cognitive decline.

Researchers are now thus studying the Tau-fighting drugs and are looking into other factors, like inflammation, brain's immune cells and certain virus.

The National Institute of Health (NIH) has expanded its focus as researchers have found more reasons for Alzheimer's. In 2013, the NIH's National Institute on Aging funded 14 trials of possible Alzheimer's drugs over a third targeting amyloid. By last fall, there were 68 drugs and 18% of them target amyloid. However, there are scientists too who think that amyloid is not everything and their is way more in the brain tissue, immune cells, and more which can be studied.

The UK is witnessing yet another outbreak of meningitis, with one college student dead and two others infected in Berkshire, according to the UK Health Security Agency (UKHSA).

According to the agency, close contacts of those affected are being offered antibiotics as a precautionary measure.

While stressing that the risk to the wider public remains low, the UKHSA confirmed that one case has been identified as Meningitis B (MenB), while further testing is ongoing.

The latest infections come after a small number of meningitis B cases were reported in the Weymouth region in April, followed by a major outbreak in Kent in March that affected more than 30 people and led to the deaths of a sixth-form pupil and a university student.

What’s The Meningitis Situation In Reading?

The young person who died attended The Henley College, according to a local GP surgery.

Authorities are reportedly sharing information about the infection with students and parents at affected schools. The other two cases are believed to be linked to schools in the Reading area. But the officials are yet to disclose the exact link.

Health officials said close contacts of the infected individuals are being offered antibiotics as a precaution.

GP surgery, the Hart Surgery, based in Henley-on-Thames, stated that it was in contact with the UKHSA due to the college’s location, adding that the agency was “actively contacting those who may be at risk due to a close association with the student involved.”

However, it said anyone whom the UKHSA has not contacted does not require treatment, and students and staff can continue attending the sixth-form college as usual.

“The number of confirmed cases is very low, so there are currently no plans for a local emergency meningitis vaccination programme,” it added.

What Is Meningitis?

Meningitis is a serious medical condition that affects the protective membranes covering the brain and spinal cord, known as the meninges. Fever is often considered one of the classic symptoms, although it may not always be present.

Understanding the symptoms, causes, and treatment options is important for early diagnosis and timely medical care.

“Anyone can get meningitis, and around 300 to 400 cases of meningococcal disease are diagnosed in England every year. It is most common in babies, young children, teenagers, and young adults," said Dr Rachel Mearkle, a consultant in health protection at the UKHSA.

“It needs to be treated quickly, so it is important to know the signs and symptoms. They can appear in any order and may not all be present, so seek rapid medical attention if there is ever any concern," she added.

The expert noted that "meningococcal meningitis requires very close contact to spread, and large outbreaks such as the one recently seen in Kent are thankfully rare."

“Meningococcal disease does not spread easily, and the risk to the wider public remains low.”

Symptoms Of Meningitis

Health officials urged the public to remain alert to the warning signs of meningococcal meningitis. Common symptoms include:

  • Rash
  • Headache
  • Neck stiffness
  • Fever
  • Drowsiness
  • Nausea or vomiting
  • Increased sensitivity to light

“If the disease is suspected, immediate medical attention should be sought, as it can progress rapidly,” the officials said. While antibiotics provide the quickest short-term protection, vaccines offer longer-term protection.

New Drug Boosts Survival Rate In Patients With Metastatic Pancreatic Cancer

Updated May 14, 2026 | 10:30 PM IST

Summary​Daraxonrasib is a once-daily oral pill that demonstrated statistically significant and clinically meaningful improvements in progression-free survival (PFS) and overall survival (OS) compared with standard intravenous chemotherapy.

Pancreatic cancer has long been one of the toughest challenges in oncology. With a five-year survival rate hovering around 13 per cent and recurrence rates approaching 80 per cent after treatment, the odds have historically been stacked against patients.

However, an experimental drug called daraxonrasib, developed by the US-based late-stage clinical oncology company Revolution Medicines, has shown promise in improving survival rates in patients with metastatic pancreatic ductal adenocarcinoma (PDAC).

“For patients with metastatic pancreatic cancer, new treatment options are urgently needed to increase survival time and improve quality of life,” said Brian M. Wolpin, professor of medicine at Harvard Medical School, and principal investigator for the trial.

Wolpin noted that the study “indicates that daraxonrasib provides a clear and highly meaningful step forward for patients with pancreatic cancer who have experienced progression on prior treatment, typically chemotherapy.”

What Is Daraxonrasib?

Daraxonrasib is a once-daily oral pill that demonstrated statistically significant and clinically meaningful improvements in progression-free survival (PFS) and overall survival (OS) compared with standard intravenous chemotherapy.

Daraxonrasib, described as a multi-selective inhibitor of RAS(ON) proteins, is the first investigational drug in a new class of RAS inhibitors designed to target a broad spectrum of cancer-causing RAS mutations.

In the clinical trial, daraxonrasib showed a median overall survival of 13.2 months, compared with 6.7 months for chemotherapy.

The drug was generally well tolerated and showed a manageable safety profile, with no new safety concerns identified.

Daraxonrasib works by blocking KRAS signalling proteins that drive tumor growth.

Pancreatic cancer is considered one of the most RAS-addicted cancers, with more than 90 per cent of patients carrying tumours driven by RAS protein mutations.

Daraxonrasib: The Clinical Trial

The controlled Phase 3 clinical trial evaluated daraxonrasib in patients with previously treated metastatic PDAC.

The trial included patients with pancreatic tumours carrying a wide range of RAS variants, as well as patients without identified RAS mutations.

The results showed that daraxonrasib significantly improved overall survival in patients with previously treated metastatic pancreatic cancer.

Similar RAS-targeting drugs are now being developed by other companies for pancreatic, lung, and colon cancers.

“It’s the beginning, not the end,” said Elizabeth Jaffee in comments to The New York Times.

What are the side effects?

According to the company, “Daraxonrasib was generally well tolerated, with a manageable safety profile and with no new safety signals.”

Prior studies with daraxonrasib have shown that rash is the most common side effect, with mouth sores, diarrhea, nausea, and vomiting also common.

FDA fast-tracks Daraxonrasib

Based on the first interim analysis, all progression-free survival and overall survival results are now considered final.

Revolution Medicines said it plans to submit the data to global regulators, including the US Food and Drug Administration (FDA), as part of a future New Drug Application under a Commissioner’s National Priority Voucher.

The findings are also expected to be presented at the 2026 American Society of Clinical Oncology (ASCO) Annual Meeting.

What Is Pancreatic Cancer? Know The Warning Signs

Pancreatic cancer typically begins in the ducts of the organ and can rapidly spread from there to the rest of the organ. Early-stage pancreatic tumors do not show up on imaging tests, making this version of the disease difficult to diagnose until it infects other organs.

The prevention and early detection remain vital.

Experts warn that pancreatic cancer often masquerades as common ailments, delaying diagnosis. Here are some early symptoms that should never be ignored:

  • Abdominal or back pain that worsens over time or eases when leaning forward.
  • Unexplained weight loss without changes in diet or exercise.
  • Jaundice, including yellowing of the eyes and skin, sometimes with intense itching.
  • Changes to urine or stool, such as dark urine or pale, greasy stools.
  • New-onset diabetes without obvious risk factors.
  • Persistent fatigue unrelated to poor sleep or lifestyle
These symptoms often appear in combination and warrant immediate medical attention — particularly for those with a family history of pancreatic cancer.

Hantavirus Outbreak: Critically Ill French Patient On Artificial Lung Support

Updated May 14, 2026 | 06:30 PM IST

SummaryUnlike COVID-19, it does not have significant aerosol or pandemic potential. Only certain strains, such as the Andes strain identified in South America, have shown limited person-to-person transmission, usually through very close or intimate contact involving body fluids.

A French woman infected with the deadly hantavirus outbreak linked to the MV Hondius cruise ship is critically ill and is being treated using an artificial lung.

The woman is among the passengers evacuated from Spain’s Canary Islands. According to the World Health Organization (WHO), 11 people have been affected by the rat-borne virus so far, of whom three have died.

A Dutch couple is believed to have been first exposed to the virus while visiting a birdwatching site in Argentina.

The WHO has confirmed that the Andes strain of hantavirus — the only strain known to spread from person to person — is behind the outbreak.

Patient Suffers Severe Lung And Heart Complications

The French passenger, currently hospitalized in Paris, has developed a severe form of the disease that has caused life-threatening lung and heart complications, Dr. Xavier Lescure, an infectious disease specialist at Bichat Hospital, told AP News Agency.

He explained that “the woman is on a life-support device that pumps blood through an artificial lung, providing it with oxygen and returning it to the body. The hope is that the device relieves enough pressure on the lungs and heart to give them some time to recover.”

Lescure described it as “the final stage of supportive care.”

With the evacuation of all passengers and many crew members completed, the MV Hondius is now sailing back to the Netherlands, where it will undergo cleaning and disinfection.

Hantavirus: No Pandemic Potential

Speaking to HealthandMe, Dr. Amitav Banerjee, professor at DY Patil Vidyapeeth, Pune, and former field epidemiologist in the Indian Armed Forces, said hantavirus does not spread easily from person to person.

Unlike COVID-19, it does not have significant aerosol or pandemic potential. Only certain strains, such as the Andes strain identified in South America, have shown limited person-to-person transmission, usually through very close or intimate contact involving body fluids.

“That is why the husband and wife may both have become infected. Even then, transmission is rare and requires prolonged close exposure. Basic precautions are generally sufficient, and asymptomatic individuals are unlikely to transmit the infection,” he said.

Dr. Amitav added that hantavirus does not have pandemic potential under natural conditions because it spreads poorly between humans and remains largely linked to rodent exposure.

Hantavirus: How to Prevent The Risk

Dr. Jatin Ahuja, Consultant in Infectious Diseases at Indraprastha Apollo Hospital, Delhi, told HealthandMe that the general public has no reason for alarm.

“Hantavirus infections remain rare globally, and awareness about rodent control and early symptom recognition continues to be the most effective approach,” he said.

He recommended simple preventive measures to significantly reduce risk.

“People should avoid sweeping or vacuuming rodent-infested areas directly, as this may spread contaminated particles into the air. Instead, affected areas should be ventilated first and cleaned using disinfectants while wearing gloves and masks. Proper storage of food, sealing entry points for rodents, and maintaining hygiene in homes, warehouses, and workplaces are also important preventive steps,” the expert added.
