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.

A sexually transmitted form of Shigella, a highly contagious bacterium that causes severe diarrhea, is spreading rapidly among gay, bisexual and other men who have sex with men (GBMSM) in the UK, according to a new study published in The Lancet Infectious Diseases.

The study, led by researchers at the University of Cambridge, found that sexually transmitted Shigella strains are spreading faster than non-sexually transmitted strains and evolving resistance to key antibiotics at an alarming rate.

“Many men who have sex with men are unaware of the serious and increasing risk posed by sexually transmitted Shigella,” said Professor Kate Baker, senior author of the study from Cambridge’s Department of Genetics.

“Sexual infection is now a sustained part of Shigella transmission in the UK. It is vital that this message reaches the communities most affected, so we can help to prevent the spread,” Baker said.

“Sexually transmissible shigellosis needs to be treated as a distinct public health threat, requiring different surveillance, prevention, and treatment strategies.”

What Did The Study Find?

Using genomic sequencing techniques similar to those used to track COVID-19 variants, researchers mapped how Shigella bacteria spread and evolved across the UK. The study, conducted in collaboration with the UK Health Security Agency (UKHSA), analyzed 3,514 laboratory-confirmed Shigella samples collected across the UK between 2004 and 2020 from people aged 16 years and older.

Sexually transmitted Shigella spread significantly faster than strains acquired through food, travel, or other non-sexual routes.

Over an evolutionary period of about 2.5 years, sexually transmitted strains spread an average of 117 km between related cases, compared with 46 km for non-sexually transmitted strains.

Sexually transmitted Shigella is primarily circulating within GBMSM sexual networks, particularly in major cities including London, Brighton and Manchester.

No statistically significant increase was seen among non-GBMSM populations, and little evidence was found that infections are spreading widely beyond these sexual networks.

More than half of all Shigella infections in the UK are now sexually transmitted.

Around 30% are linked to international travel, while the remaining cases result from localized outbreaks, particularly among young children, and household transmission.

Professor Baker recommended the following steps to reduce the risk of sexually transmitted Shigella:

• Avoid sexual activity if you have diarrhea or are recovering from a recent diarrheal illness.
• Wait at least two weeks after you have fully recovered before resuming sexual activity.
• Tell your doctor about your sexual history if you seek medical care for diarrhea or related symptoms.
• Ask for a comprehensive sexual health screening if you may have been exposed.

Growing Antibiotic Resistance Raises Concern

Researchers found that antibiotic-resistant sexually transmitted Shigella strains are spreading 71% faster than drug-susceptible strains. More than 70% of sexually transmitted Shigella strains were resistant to at least one clinically important antibiotic.

“This isn’t just one form of sexually transmissible diarrhea. This is multiple overlapping variants emerging that are all quickly becoming resistant to the drugs we use to treat them,” said Baker. “It’s highly likely that if you contracted your Shigella through sex you require different treatment to someone who contracted it through travel.”

Researchers also believe the rise in resistance may partly be driven by antibiotics prescribed to treat or prevent other sexually transmitted infections.

“Our evidence suggests that the variants of Shigella transmitting in sexual networks were actually getting resistant against treatments for other STIs, like gonorrhoea, so people need to remember that when they’re taking antibiotics they’re treating their whole body,” said Baker.

As the world celebrates football through FIFA, new research is drawing attention to the long-term health risks faced by athletes in American professional football.

A new study found that former NFL players are nearly four times more likely to die from neurodegenerative diseases like dementia, Parkinson's disease, and amyotrophic lateral sclerosis (ALS), than the general U.S. population.

About The Study

A major new study has found that former National Football League (NFL) players are nearly four times more likely to die from neurodegenerative diseases like dementia, Parkinson's disease, and amyotrophic lateral sclerosis (ALS) than the general population.

The research raised concerns about the long-term impact of repeated head injuries in professional football.

Published in eClinicalMedicine, the study analyzed mortality data from 19,824 NFL players who played at least one professional game between 1960 and 2019. The researchers from Mass General Brigham, Boston University, and the Concussion & CTE Foundation compared their health outcomes with those of the general U.S. population.

The co-senior author, Daniel Daneshvar, Harvard Medical School associate professor and chair of the Department of Physical Medicine and Rehabilitation at Spaulding Rehabilitation Hospital said, “This is the clearest population-level evidence we have ever had that NFL players are dying due to neurodegenerative disease at real and measurably higher rates.”

He added, “This study demonstrates that, when looking at athletes who have played in an NFL game, including nearly 20,000 players, across every official cause of death, the result is the same: NFL players are dying of dementia and Parkinson’s disease three to four times more often than they should.”

Despite having a lower overall risk of death than the average American, former NFL players experienced a dramatic increase in deaths linked to neurodegenerative diseases. Specifically, dementia-related deaths were 3.8 times higher, while deaths from Parkinson's disease were 3.88 times higher than expected.

Even after adjusting for other known risk factors, neurodegenerative mortality remained approximately three times higher than in the general population.

Risk Even Higher Among Younger Players

Researchers found that the risk was particularly alarming among players who died before the age of 60. In this group, deaths from neurodegenerative diseases were more than 12 times higher than expected compared with the general population.

The study also identified a clear dose-response relationship between years spent in the NFL and disease risk. Players whose careers lasted five seasons or longer had nearly double the risk of neurodegenerative death compared with those who played between one and four seasons.

According to study co-senior author Dr. Jesse Mez of Boston University's CTE Center, the study supports evidence of long-term brain disease due to repeated head impacts.

"A fourfold increase in dementia rates from a presumed environmental cause is immense," Mez said, adding that previous brain bank studies suggest chronic traumatic encephalopathy (CTE) is most likely a major contributor.

Why Overall Mortality Was Lower

Interestingly, the researchers found that NFL players actually had lower overall mortality, with reduced deaths from cancer, cardiovascular disease, and suicide compared with the general population.

The team proposed the Selection Through Athletic Resilience Survivor (STARS) effect. They suggest that individuals who reach the NFL often have exceptional physical fitness, resilience, healthier lifestyles, and better access to healthcare, all of which contribute to longer overall survival.

However, these advantages make the elevated rates of neurodegenerative disease even more striking. Researchers argue that because NFL players are generally healthier than average, the true effect of repetitive head impacts on brain disease could actually be underestimated.

The findings add to growing evidence linking repeated head trauma in contact sports to long-term neurological damage and are likely to intensify discussions around concussion prevention, player safety, and long-term monitoring of athletes.

The Trump administration recently launched an initiative, encouraging hospitals across the United States to improve the quality of the meals they serve in terms of nutrition.

Launching the voluntary initiative aimed at making healthier meals more accessible to patients, visitors, and healthcare workers, the announcement was made by the U.S. Department of Health and Human Services (HHS).

About ‘Make Hospital Food Healthier’ Pledge

The initiative, announced by the U.S. Department of Health and Human Services (HHS), is part of Trump administration's “Make Hospital Food Healthier” pledge.

Hospitals that participate commit to offering more nutritious food and beverage options, increasing transparency around nutritional information, and creating food environments that better support long-term health.

Health officials say hospitals should set an example by promoting healthy eating rather than offering meals and snacks that are high in sugar, sodium, and saturated fats.

HHS said while announcing the initiative, “Healthcare facilities should reflect the same evidence-based nutrition principles they encourage patients to follow after they leave the hospital.”

Under the voluntary pledge, participating hospitals are encouraged to:

• Increase the availability of fruits, vegetables, whole grains, and minimally processed and plant-based protein options.
• Include vegetables, fruits, legumes, nuts, seeds, seafood, and healthy fats.
• Reduce the prominence of sugary drinks and ultra-processed snacks.
• Use baked, broiled, roasted, stir-fried, or grilled preparation methods and avoid deep frying.
• Make healthier meals easier to identify through nutrition labeling and clear menu information.
• Improve cafeteria and vending machine offerings for employees and visitors.
• Incorporate nutrition into overall patient wellness and recovery plans.

The administration says these changes will help create healthier food environments while supporting the prevention of chronic diseases like obesity, type 2 diabetes, and cardiovascular disease.

The Goal Behind

Millions of Americans eat meals in hospitals each year, whether as patients, family members, or healthcare workers. Public health experts have always argued that hospitals should encourage eating habits instead of relying heavily on processed foods and sugar-sweetened beverages.

Improving hospital food can also benefit healthcare staff, who often work long shifts and depend on hospital cafeterias and vending machines for meals.

The initiative supports the idea that nutrition plays a significant role in preventing and managing chronic illnesses, which remain one of the leading causes of death and healthcare spending in the United States.

The HHS pledge is voluntary, meaning hospitals are not required to participate. Instead, the department is encouraging health systems to adopt healthier food standards as part of their commitment to patient care and community health.

Officials say hospitals that join the pledge can help reinforce healthy lifestyle choices beyond clinical treatment by making nutritious foods more readily available throughout their facilities.

While the program does not mandate specific dietary standards, it represents another step in Trump administration's broader effort to promote healthier eating environments within healthcare settings.

As more hospitals sign on, health officials hope the initiative will have a positive impact on how healthcare institutions approach nutrition, turning hospitals into places that support healthy choices both inside and outside the examination room.
