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.

The National Institute of Virology (NIV) in Pune has confirmed Nipah virus infection in a 43-year-old man from Ramanattukara in Kerala's Kozhikode district.

The patient, who was earlier shifted from a private hospital to a dedicated Nipah isolation facility at Kozhikode Government Medical College Hospital, remains in critical condition and is currently on ventilator support under the close supervision of a team of specialists, as per officials.

The patient was initially transferred to the Medical College Hospital after testing positive in a preliminary examination conducted at the Virus Research and Diagnostic Laboratory (VRDL). Following preliminary test results that suggested Nipah infection, the Kerala Health Department swung into action and intensified surveillance and containment measures in Kozhikode district.

77 Contacts Identified Through Tracing Efforts

After confirmation from NIV Pune, health authorities launched extensive contact-tracing efforts. District officials have identified 77 people who may have been exposed to the patient through contact tracing:

Notably, the patient's immediate family members—including his wife, two children, father, and mother—have been placed under quarantine.

In addition, two staff members of a private hospital in Kozhikode who interacted with the patient during earlier treatment have also been advised to remain in quarantine. Samples from five primary contacts have been sent to the VRDL laboratory for testing, as per media reports.

No Need for Containment Zone Yet, Says Minister

As per District Collector M.S. Madhavikutty, none of the identified contacts are currently showing symptoms and there is no immediate need to declare a containment zone.

Health Minister K. Muraleedharan also stated that the current situation does not warrant the declaration of a containment zone in Ramanattukara.

"The 15 priority contacts have been advised to remain in quarantine. A rapid response team meeting was held to ensure the availability of PPE kits and gloves. There is no shortage of medicines, and additional supplies will arrive from Chennai," the minister said.

Officials Probing Possible Source of Infection

The patient's initial symptoms included a high fever about a week ago and was later hospitalized with symptoms suggestive of encephalitis. But as his condition worsened, doctors tested for Nipah infection, which turned positive.

He is likely to have been exposed to the virus while cleaning an old godown in Puthukad, Malappuram district, reportedly connected to his soap manufacturing business.

Another likely source of infection is a chikoo tree located on the patient's property, where officials have reportedly observed the presence of bats and bird droppings.

"Anyone developing fever should voluntarily isolate themselves, wear a mask, and avoid close contact with others. However, making masks mandatory for the public is not being considered at present, as the situation does not require such a measure," Madhavikutty told reporters.

This is the 11th Nipah outbreak reported in Kerala since the virus was first detected in the state in 2018.

What Is Nipah Virus?

According to the World Health Organization, Nipah virus is a zoonotic disease, meaning it can spread from animals to humans. It can also be transmitted through contaminated food and, in some cases, directly from person to person.

In humans, infection can range from asymptomatic illness to severe respiratory disease and fatal encephalitis (brain inflammation). The virus can also infect animals such as pigs, causing significant economic losses for farmers.

Although outbreaks have been limited mainly to parts of Asia, the virus is known for its high fatality rate and potential to cause severe disease.

Symptoms of Nipah Virus Infection

Common symptoms include:

• Fever
• Headache
• Breathing difficulties
• Cough and sore throat
• Diarrhea
• Vomiting
• Muscle pain
• Severe weakness
• Dizziness
• Altered consciousness in severe cases
• Encephalitis (brain inflammation)

Why Is Nipah a Concern?

Nipah virus is considered a major public health threat because of:

• Its high mortality rate
• The ability to spread through close contact
• The absence of a specific antiviral treatment
• The lack of an approved vaccine for widespread use

People who survive Ebola virus disease (EVD) may continue to experience memory loss, irritability, and difficulty concentrating for more than seven years after recovering from the infection, according to a new study led by researchers at the National Institute of Neurological Disorders and Stroke, part of the National Institutes of Health (NIH).

The findings come as Ebola outbreaks continue in the Democratic Republic of Congo and Uganda, where confirmed cases have surpassed 650 and more than 130 deaths have been reported.

Long-Term Neurological Problems

The NIH partnered with Liberia's Ministry of Health to study the long-term effects of the disease during the 2014–2016 Ebola epidemic in West Africa, which caused more than 28,000 infections and over 11,000 deaths across Liberia, Guinea, and Sierra Leone.

Researchers evaluated 148 adult Ebola survivors and 81 uninfected close contacts who served as a comparison group. The results revealed that many people experienced significant neurological symptoms during the acute phase of the illness, some of which continued for seven long years.

During infection, survivors commonly reported headaches, altered mental status, and stroke-like symptoms. Long-term complications affected the brain and nervous system and included cognitive dysfunction, persistent headaches, sleep disturbances, depression, sexual dysfunction, tremors, fatigue, cranial nerve abnormalities, and abnormal sensations.

The researchers also found that headaches and neurological abnormalities remained more common among Ebola survivors than in people who had not been infected.

"Over time, survivors' symptoms and neurological examinations improved; however, more than 7 years later, a significant proportion continue to endorse memory loss," the researchers wrote in the study, published in JAMA Neurology.

The study noted that many participants experienced symptoms similar to those seen in other post-infection conditions, including Long COVID and myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). These symptoms included headaches, memory loss, fatigue, and difficulty concentrating.

"This suggests possible shared pathophysiology, including persistent viral antigen or immune dysregulation," the researchers said.

However, the authors pointed out some important differences. While Long COVID and ME/CFS are often associated with autonomic nervous system dysfunction, such problems were not clearly identified among Ebola survivors, although dizziness and light-headedness were common.

How Does Ebola Affect the Brain?

The exact cause of long-term neurological problems after Ebola infection remains unclear. The researchers explained that during the acute illness, brain-related symptoms may be due to widespread inflammation, electrolyte imbalances, low blood pressure, blood-clotting abnormalities, or direct infection of the brain and nervous system by the virus.

On the other hand, long-term neurological issues may stem from persistent immune system changes, prolonged recovery from severe illness, or lingering viral material in the body.

The researchers emphasized that neurological care should be a priority for clinicians treating Ebola survivors.

"Survivors experienced headaches, memory loss, and fatigue that may significantly impact quality of life," the authors wrote.

They noted that headaches often respond to standard preventive treatments, but survivors should continue to be monitored because of the rare risk of Ebola-related relapse in the central nervous system.

The study also found that many survivors experienced symptoms of depression, including suicidal thoughts. Because symptoms such as headaches, memory problems, concentration difficulties, and sleep disturbances can overlap with psychiatric disorders, the researchers stressed the importance of mental health evaluation and care.

Fortunately, many of these symptoms appear to improve or resolve over time with appropriate treatment and support.

Will Bundibugyo Survivors Face Lasting Brain Issues?

The current Ebola outbreak is caused by the Bundibugyo strain, which differs from the strain responsible for the 2014–2016 West African epidemic. Unlike the Zaire strain, there are currently no approved vaccines or antiviral treatments specifically for Bundibugyo Ebola, although some patients have recovered.

Researchers believe many of the long-term neurological effects observed in survivors of the West African outbreak could also occur in Bundibugyo survivors.

The World Cup is at the doorstep, and fans are excited to witness their favorite stars once again in their clash to get the golden trophy. It has been over 20 years since the World Cup returned to the US, though Canada and Mexico are also among the hosts. The fans are reaching America from all over the world. The players are also ready to make their mark on the largest scale of the sport.

Thus, it becomes crucial to keep the athletes fit and healthy. There is a huge team behind the scenes to treat and take care of your favorite stars, which requires strategy, planning, and most of all, accurate execution. On this backdrop comes a name that makes the difference known as the Pro Sports Doc, Riley J. Williams III, who is known to be an expert, and he will coordinate medical care during this demanding tournament.

The Pro Sports Doc, with his 20 years of experience, will be working and coordinating medical care in the New York / New Jersey area. In an interview with Muscle and Fitness, Riley J. Williams III put emphasis on players getting acclimatized and synchronizing their sleeping patterns with North America. He also mentioned creatine as a great health supplement. He also reveals that his team has readied the entire spectrum of possible medical issues that might occur while teams are in the market.

FIFA has also issued standard procedures to keep the players safe. Each Participating Member Association shall include at least one team medical doctor in its delegation, to be present in the technical area during all matches. It is a mandatory requirement that the team medical doctor of each Participating Member Association complete and successfully pass the “Concussion” and “Sudden Cardiac Arrest” modules of the FIFA Diploma in Football Medicine before the FIFA World Cup 26.

The team's medical doctor is responsible for the overall health of their team delegation and any clinical decision‑making in this regard, both on and off the field of play. Although the team doctors’ primary responsibility is to the players, their medical responsibility extends to all other members of the delegation. As such, all team doctors shall ensure that they have the appropriate registration and licence in their home country.

Each Participating Member Association shall ensure and confirm to FIFA that its players have undergone a cardiac screening, including personal and family history, clinical examination, and resting 12‑lead ECG, within the last 12 months and an echocardiography within the last 24 months before the start of the final competition of the FIFA World Cup 26. If specifically performed for the tournament, FIFA recommends that participating teams use the screening form developed by FIFA cardiology consultants.
