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 United States shelved the decision to vaccinate poultry as a bird flu prevention measure due to HHS Secretary Robert F. Kennedy Jr.’s skeptical vaccine views

According to a Politico report, the move came as highly pathogenic avian influenza, especially the H5N1 strain, continues to affect poultry farms, threatening bird populations, disrupting egg supplies and raising concerns about transmission to humans.

According to Politico's findings, five people who were involved in the decision-making said that Agriculture Secretary Brooke Rollins pulled back an internal strategy for vaccinating poultry and hens that lay eggs.

The plan was initially intended to be shared with governments of other countries, industry leaders and other stakeholders to help boost bird flu response.

However, it remains unclear whether Kennedy directly asked Rollins to halt the strategy. However, concerns about how poultry vaccination would be received by the health secretary reportedly influenced the decision to keep the document away from wider circulation.

Why Was The Poultry Vaccination Plan Shelved?

The US Department of Agriculture (USDA) announced a $1 billion bird flu response strategy in February 2025. The plan included $500 million for farm biosecurity, $400 million in financial relief for farmers and $100 million for vaccine research.

Despite the resources, an internal poultry vaccination strategy reportedly failed to be executed as planned. One person familiar with the process told Politico that the technical and communication components were already in place by the summer of 2025, but the final document was circulated among fewer than a dozen people.

Kennedy has publicly opposed vaccinating poultry against bird flu, arguing that vaccines that do not completely prevent infection could allow the virus to continue evolving.

In a March 2025 interview with Fox News host Sean Hannity, Kennedy warned that using vaccines that do not provide complete protection could turn poultry flocks into “mutation factories”.

He argued that allowing the virus to circulate among birds could help identify animals with natural immunity. The proposal attracted criticism from veterinary and vaccine experts, who warned that permitting uncontrolled infections could, in turn, increase viral replication and create opportunities for mutations.

Dr Gail Hansen, a former state veterinarian for Kansas, criticised the idea of allowing bird flu to spread through poultry populations, calling it a “really terrible idea, for any one of a number of reasons”. She warned that a virus circulating through a flock containing millions of birds would have many opportunities to evolve or mutate, which increases the risk to other animals and farm workers.

Can Vaccinating Poultry Help Control Bird Flu?

Vaccination is one the effective tools for reducing bird flu infections and containing transmission. However, vaccines do not always provide sterilising immunity, meaning vaccinated animals may still become infected even if they are protected against severe disease.

So, if vaccination reduces visible symptoms without fully preventing infection, infected birds may be harder to identify unless monitoring systems are efficient.

However, this does not mean vaccination inevitably creates dangerous mutations. The evolution of viruses occur naturally, and vaccination can reduce the number of opportunities for viral replication. The overall effect depends on the vaccine effectiveness, surveillance, biosecurity and how the nature of the virus.

Countries including France, China, Egypt and Mexico have used poultry vaccination against avian influenza. In the US, the USDA granted conditional approval for an avian influenza vaccine in 2025, but poultry vaccination has not been adopted yet.

H5N1 has infected people following exposure to infected animals, but sustained human-to-human transmission has not been established yet. Hence, preventing infections in poultry remains important for reducing opportunities for the virus to spread and evolve.

The Keralam government has introduced the Keralam Senior Citizens (Care and Protection of Rights) Bill, 2026, to regulate elderly-care facilities and services. It proposes mandatory registration of care centers and caregivers, prescribed standards, caregiver certification, and penalties for violations.

Referred to the Assembly’s subject committee, the Bill would establish a legal framework for elderly care if passed.

Keralam introduced its first elderly-care policy in 2006, updated it in 2013, and released a draft State Policy for Elder Persons in August 2025. The state also enacted the Kerala State Senior Citizens Commission Act, 2025, and has a dedicated department for senior citizens’ welfare.

Why Does Keralam Need The Bill?

Chief Minister V. D. Satheesan introduced the Bill, expressing confidence that it would make Kerala a model for elderly care.

“Nobody should feel that they are alone or abandoned. The way a society treats its elderly determines how civilized it is,” he said.

Keralam has one of India’s largest elderly populations, partly due to its high life expectancy. Older adults are projected to account for 22.8% of the state’s population over the next decade, up from 18.7%, highlighting the growing need for care services.

What Does The Bill Propose?

• Dignity and care: Promotes ageing in place, home-based care, safety, and social inclusion.
• Access and rights: Seeks better access to healthcare, legal aid, safe public spaces, digital inclusion, and abuse-reporting mechanisms.
• Protection units: Proposes state and district-level bodies to monitor care services and address complaints.
• Care-centre regulation: Requires registration of senior citizen care centres and sets service standards.
• Caregiver certification: Proposes training, phased certification, a Keralam Geriatric Care Certification Framework, and a state register of caregivers.
• Cybercrime safeguards: Proposes a Senior Citizen Cyber Fraud Cell at every cyber police station.
• Welfare funding: Calls for a state reserve fund for care, protection, welfare, and social security.
• Penalties: Provides for punishment for violations of the proposed law and related rules.

Speaking to HealthandMe, Dr. Rajeev Jayadevan, Ex-President of IMA Cochin and Convener of the Research Cell, Kerala, said the principles outlined in the Bill could eventually apply across India, particularly as Keralam has a higher proportion of older adults than many other states.

With shrinking nuclear families and urbanization, fewer family members may be available to provide full-time care, increasing reliance on state-supported services, including home care, medical consultations, and palliative care.

He emphasized that older adults have distinct care needs and highlighted patient autonomy in end-of-life decisions. Living wills allow people to document their medical-care preferences in advance, helping families and healthcare professionals understand their wishes and potentially avoid unwanted interventions.

Dr. Rajeev also stressed the need for trained, certified caregivers, effective oversight of care providers, and safeguards against elder abuse.

As older adults increasingly use digital platforms for services such as banking, digital literacy and protection against online scams and financial fraud are also essential, he noted.

India’s senior citizen population is projected to reach around 230 million by 2036, or approximately 15% of the population. Southern states, along with Himachal Pradesh and Punjab, have larger elderly populations, with regional disparities expected to widen.

Moody’s Ratings said in September that India’s population is expected to age significantly as fertility falls below replacement levels.

Older adults often face chronic conditions such as diabetes, high blood pressure, and high cholesterol, alongside complications including diabetic kidney disease, diabetic retinopathy, cataracts, and glaucoma. These health needs underscore the importance of accessible, coordinated long-term care.

CVS Pharmacy and its subsidiaries have agreed to pay $315 million to settle a US Department of Justice lawsuit alleging that the pharmacy chain unlawfully dispensed opioid prescriptions that were not needed medically.

The settlement, announced on October 13, also requires the company to implement safeguards against inappropriate and unnecessary dispensing.

Filed in December 2024, the lawsuit alleged that CVS dispensed prescriptions that lacked a legitimate medical purpose, involved excessive quantities of opioids or were dispensed too early.

The government also alleged that the company filled prescriptions from so-called “pill mills”, suppliers who are accused of issuing large numbers of controlled-substance prescriptions without a legitimate medical purpose. CVS has strongly disputed the allegations and denies any wrongdoing as part of the settlement. The agreement resolves the civil claims without a determination of liability.

Unsafe Opioid Prescriptions Can Increase Addiction Risk

Opioids are powerful medications used to treat moderate to severe pain. They include prescription drugs like oxycodone, hydrocodone and morphine.

When prescribed appropriately and taken under medical supervision, they can provide important relief. However, their effects on the brain'can also lead to dependence and addiction issues.

Dependence and addiction are related but different. Physical dependence occurs when the body adapts to a medication. If stopped abruptly, one may experience severe withdrawal symptoms.

Opioid use disorder, commonly referred to as opioid addiction, involves a destructive pattern that can include cravings, loss of control and continued use despite harmful consequences.

The risk increases when these opioids are prescribed or taken in excessive doses or combined with other similar medicines. Taking more than prescribed can also increase the risk of overdose, which can slow or stop breathing and may be fatal.

The Justice Department's lawsuit alleged that CVS dispensed prescriptions for dangerous combinations of medicines, including “trinity” prescriptions combining an opioid, a benzodiazepine and a muscle relaxant. Such combinations can lead to a compounded sedation effect and respiratory depression, increasing the risk of serious harm.

In these cases, addiction becomes more than just a habit. These substances alter brain chemistry, particularly in the areas related to reward, motivation, and self-control. Hence, recovery is not simply about choosing to quit.

Addiction hijacks the brain’s prefrontal cortex—the area responsible for decision-making, self-control, and judgment. As a result, people suffering from addiction are often unable to regulate their behavior, even when they want to.

The brain’s reward system reinforces substance use by releasing dopamine, the chemical associated with pleasure and reward. Over time, the brain becomes dependent on this chemical surge, leading to tolerance (needing more of the substance to feel the same effect) and withdrawal symptoms when the substance is not available.

What Did The Lawsuit Allege?

According to the Justice Department, the alleged dispensing practices occurred between October 2013 and December 2025. The government claimed that staffing shortages, performance targets and incentive policies contributed to pharmacists filling prescriptions without adequately checking whether they were legitimate.

Many of the prescriptions were allegedly billed to federal healthcare programmes, including Medicare and Medicaid, prompting claims under the federal False Claims Act as well as the Controlled Substances Act.

“Today's settlement is a significant milestone in the Justice Department's efforts to combat the opioid epidemic by cracking down on pharmacies who unlawfully fulfill prescriptions for controlled substances,” Associate Attorney General Stanley Woodward said in a statement.

CVS said its pharmacists were trained “in the safe and appropriate use of all medications” and that the company had introduced programmes to help them make appropriate decisions for patients.
