The US Food and Drug Administration has approved TNKase or Tenecteplase, which is a thrombolytic or clot-dissolving agent, for the treatment of acute ischemic stroke in adults.

Ischemic strokes happen when a blood clot blocks a blood vessel in your brain. It can cause permanent brain damage and death. If enough brain cells die, you can also lose the abilities or body functions those cells control. They are also the most common types of stroke, with 80% of all strokes being ischemic strokes.

How is TNKase administered?

It is delivered as a single five-second intravenous bolus, which is faster than the standard of care Activase or alteplase, which is administered as an intravenous bolus followed by a 60-minute infusion. The manufacturer of TNKase, Genetech said a new 25-mg vial configuration will also be available in the coming months.

How Was TNKase approved?

The approval came at the backdrop of a study that compared TNKase to Activase in patients with acute ischemic stroke. These patients also presented with a disabling neurological deficit. Results show that TNKase was comparable to Activase in terms of efficacy and safety.

How Common Are These Strokes?

In the United States it self, it affects more than 795,000 people each year and is the leading cause of long-term disability. It is also the fifth leading cause of death. Since brain damage can happen if this progresses rapidly, one needs an immediate, fast-acting medical care.

TNKase thus provide a faster and simpler administration which can be critical for anyone. The chief medical officer and head of global product development at Genetech, Levi Garraway, MD., PhD., said, "Today's approval is a significant step forward and underscores our commitment to advancing stroke treatment options for patients."

What Are The Symptoms Of Ischemic Strokes?

Some of the most common symptoms include weakness or paralysis on one side of your face and body. You may also feel trouble speaking or have loss of speech, also known as aphasia. You may faced slurred or garbled speaking, also known as dysarthria. Other symptoms include loss of muscle control on one side of your face, or sudden worsening or loss of your senses, including vision, hearing, smell, taste, and touch.

Other symptoms include:

• Loss of coordination or clumsiness
• Blurry vision or double vision
• Dizziness or vertigo
• Nausea and vomiting
• Neck stiffness
• Mood swings or sudden personality changes
• Confusion or agitation
• Seizures
• Memory loss (amnesia)
• Headaches which are sudden and severe
• Passing out or fainting
• Coma

Are There Any Warning Signs?

While these are symptoms one has who is prone to this condition. However, often, many may confuse it with other illnesses. It is best to keep an eye out for warning signs. These could be looking out for yourself or your loved one. Note if there is a sudden loss of balance. Look out for sudden vision loss or changes in one or both eyes. Look for a droop on one or both sides of your face, especially when you smile. Raise both arms and see if one arm sags or drops in a way it usually does not. Note for your speech. Are you as fluent? Are you have trouble speaking? If you see any of such signs, start tracking it and talk to your healthcare provider.

Plague is highly treatable if caught early, newly appointed CDC Director Erica Schwartz said, adding that the US is monitoring travelers arriving from Siberia following the reported death of a worker in Russia.

Speaking at the WSJ’s Future of Health event, Schwartz said the risk to the US from an unconfirmed case of pneumonic plague in Siberia was extremely low. She noted that the reported illness involved Yersinia pestis, the bacterium that causes plague.

“It’s a bacterial disease, a very serious bacterial disease. The one good thing is that it’s a treatable, highly treatable bacterial disease with common antibiotics that most physicians within the United States can utilize,” Schwartz said.

“This is a disease that is spread person to person through respiratory droplets, but as I said, if we can identify cases early, they’re absolutely treatable,” she added.

Schwartz said the CDC was prepared to monitor and screen travelers, particularly those arriving from Russia. She also discussed steps public health officials are taking to ensure Americans are protected from a potential threat linked to the reported case in Russia.

“There are about 200 flights that come into the United States from Siberia, that region. We are working with Department of Homeland Security, working (with) Department of State, Department of War, and other agencies within the government to make sure that we know exactly if anyone from that area comes into the United States,” Schwartz said.

She said flights from Siberia, where the plague-linked Irkutsk Anti-Plague Research Institute is located, typically arrive at JFK International Airport.

“We have a port health station set up in JFK so that we can do appropriate surveillance and screening if anyone from that area comes into the United States. So we’re very well positioned to make sure that we are protected from a potential threat like that,” Schwartz said.

An HHS spokesman said about 200 individuals per year from the Siberian region travel to the United States. Direct flights between Russia and the United States have been suspended since the start of the Ukraine war in 2022.

Russia Plague: What We Know So Far

Russia has reportedly seen two deaths allegedly linked to pneumonic plague. One was Darya Shipilova, a 28-year-old laboratory technician at the Irkutsk Anti-Plague Research Institute. The identity of the other person remains unknown.

Shipilova fell ill on September 29, was placed on a ventilator, and died on October 2. Around 200 contacts were reportedly placed under medical observation after she allegedly told doctors that she had accidentally broken a test tube containing live bacteria.

However, Russian authorities maintain that Shipilova died from “unidentified pneumonia”. Authorities said tests of her contacts found no dangerous infectious-disease pathogens, although some reportedly tested positive for COVID-19 or rhinovirus.

Russia has also denied reports of a second death linked to plague, calling them “fake news”.

In a statement published by Russian news agencies, the regulator denied what it called “fake information circulating on social media regarding a second case of illness”.

It said it had completed checks on all contacts of the dead woman, adding that “no health issues related to an infectious disease were detected” and that nearly 5,000 laboratory tests showed no dangerous pathogenic microorganisms, Reuters reported.

US President Donald Trump and Senator Rand Paul have publicly criticized Russia’s handling of the situation, with Trump calling it a “big problem for Russia” and Paul accusing Russia of not fully cooperating with international health authorities.

The XFG COVID-19 variant is driving a rise in cases and hospitalizations in the UK and France, while some US regions are also reporting increases.

XFG, nicknamed ‘American COVID’ or Stratus, is a recombinant SARS-CoV-2 variant from the Omicron lineage, formed from LF.7 and LP.8.1.2. The WHO recorded the earliest documented XFG sample on January 27, 2025, and designated it a variant under monitoring in June 2025.

The NHS has advised infected people to stay home to limit spread. The UK is rolling out COVID vaccination, while France is expected to begin its campaign next week.

COVID and flu symptoms can overlap, including cough, fever, sore throat, headache, runny nose and fatigue.

COVID Activity Rises in UK, France

In France, the estimated number of people with COVID consulting GPs for acute respiratory infections rose to 13 per 100,000, from nine the previous week, according to The Connexion. This translates to around 8,806 new cases, up from about 6,000.

In England, hospital PCR positivity rose from 5.9% to 7.0% in the week to September 20, while hospital admissions increased from 0.81 to 1.20 per 100,000. Overall activity remained low.

US CDC data from September 29 showed cases rising in some states while falling or remaining stable in others.

Is India At Risk?

HealthandMe spoke to experts who said the UK-France rise does not necessarily mean India will see a similar increase.

“The rise in COVID-19 cases in the UK and France does not necessarily mean that India is headed towards a similar increase,” said Dr Suranjit Chatterjee, Senior Consultant, Internal Medicine, Indraprastha Apollo Hospitals, Delhi.

XFG is being monitored because it has become more common in some countries, but available evidence does not indicate that it causes more severe illness than other circulating variants.

“For India, the more relevant question is whether XFG is increasing locally and whether this is translating into a rise in symptoms or hospitalizations,” Dr Suranjit told HealthandMe .

Does XFG Cause More Severe Disease?

Dr Amit Prakash Singh, Consultant - Internal Medicine, CK Birla Hospital, Delhi, said the spread of XFG highlights the need for continued surveillance as SARS-CoV-2 evolves.

“Yet at present there is no evidence to indicate that the XFG variant causes more severe disease than the other Omicron-lineage variants,” he said.

However, the “main concern for India would be a greater rate of transmission, especially among older people, those with comorbidities and the immunocompromised, should the variant become more common in the country”.

Dr Amit told HealthandMe India should continue genomic surveillance and monitor hospitalizations and severe disease rather than focusing only on case numbers.

Dr Suranjit said international travel can introduce new variants, but their impact depends on community spread and existing immunity.

“At this stage, there is no reason for people (in India) to be unduly concerned or change their daily routine.”

He added that continued surveillance, timely testing when symptoms occur and sensible precautions during respiratory infections remain appropriate.

Are XFG Vaccines Available?

XFG-specific vaccines have been developed and are either in use or authorized in several countries. The US and UK have opted for XFG-targeted formulations for the 2026–27 season.

In India, an XFG-specific vaccine should be considered available only after regulatory approval and commercial supply.

The WHO continues to stress that vaccination should not be postponed while waiting for an updated formulation.

Canada has determined to restrict medical assistance in dying (MAID) for patients whose sole underlying condition is a mental illness, shelving plans to expand the eligibility in 2027.

Justice Minister Sean Fraser said the government will introduce legislation to maintain the exclusion beyond the current deadline of March 17, 2027.

The decision comes weeks after an Ontario court rejected a woman's request for an exemption that could have allowed her to seek MAID because of severe, longstanding mental illness.

Canada Extends Ban On Medical Assistance In Dying

The government says there is still no sufficient medical consensus on when a mental illness can be considered irremediable, a key requirement under Canada's MAID policy.

Fraser said, “When I hear that there is a lack of consensus within the medical community about the irremediable nature of certain mental illnesses, that gives me real cause for concern.” He also pointed out that access to mental health care in the country is uneven.

He acknowledged that the issue does not have unanimous agreement but defended the government's decision. “While there is not a perfect consensus on this issue, we believe this is the correct approach at this particular time,” Fraser said.

Canada had originally kept the exception as temporary. When MAID eligibility was expanded in 2021 to people whose natural death was not reasonably foreseeable, mental illness as the sole underlying condition that was deemed ineligible.

The exclusion was subsequently delayed several times, with March 2027 becoming the latest planned date for possible expansion.

Ontario Court Rejected A Woman’s MAID Request

The announcement comes just after a controversial case involving Claire Elyse Brosseau, a 49-year-old Toronto woman who sought a constitutional exemption from the existing MAID exclusion.

Brosseau said she has lived with severe mental-health problems for decades and had undergone multiple forms of treatment. In May, she asked the Ontario Superior Court for emergency relief that would allow her to apply for MAID.

On September 3, Justice Carissima Mathen rejected that request. She also ordered the federal government to respond to Brosseau's constitutional challenge to the exclusion.

Mathen described Brosseau's evidence of suffering as credible and compelling, but said the case also involved Parliament's role in making decisions on “sensitive social issues” and interpreting the Charter rights involved.

Brosseau, meanwhile, said the decision was nothing but another barrier for people with mental illness. “It is yet another example of governmental systems telling people with mental illnesses that we do not have the same rights nor the same autonomy as others,” she said.

Parliament Had Already Recommended An Indefinite Exclusion

The government's decision also follows a recommendation that was passed in June from a joint parliamentary committee, which called to exclude people from MAID eligibility whose only underlying condition is mental illness.

The committee's review highlighted disagreements among experts over whether clinicians can reliably determine that certain mental illnesses are permanently irremediable.

It was based on a report that 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, the recommendation was not unanimous. Four senators issued a dismissed the report, questioning the committee's process, arguing that the government should consider seeking guidance from the Supreme Court of Canada.

The government's proposed legislation is expected to circle back to advance requests, which is another another debatable aspect of MAID.

Under the proposed changes, people diagnosed with serious illnesses who may eventually lose the ability to consent could be able to make an advance request for MAID.

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".
