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.
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.
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.

For the first time, starting July 1, people in the US will be able to access GLP-1 drugs for weight loss through a new pilot program offered by the federal health insurance program Medicare.
Until now, Medicare covered GLP-1 medications such as Ozempic only for certain conditions like diabetes, but not for weight loss.
The new 18-month Medicare GLP-1 Bridge Program, which will run till the end of 2027, aims to make these high-cost weight-loss medications more accessible to eligible beneficiaries.
According to a KFF analysis of 2023 Part D enrollment data, an estimated 3.8 million Medicare beneficiaries could qualify for the program.
More than 70 per cent of adults in the United States are considered to have obesity or screen as overweight. Studies have proven that GLP-1s are an effective tool in weight reduction, as well as improving other markers of good health, such as blood pressure, lipid profiles, and blood sugar levels.
Eligible beneficiaries will be able to access the following GLP-1 weight-loss medications:
The medications will be covered only when prescribed for weight management and when beneficiaries meet the program's medical eligibility criteria.
The program is available only to certain members of Medicare Part D prescription drug plans who want to lose excess weight and maintain weight loss.
Although the program operates outside standard Medicare Part D coverage, beneficiaries can participate only if they are enrolled in:
People enrolled in certain less common Medicare plans, including the Program of All-inclusive Care for the Elderly (PACE), may also qualify if they also have a stand-alone Part D plan, Washington Post reported.
According to the Centers for Medicare & Medicaid Services (CMS), most of Medicare's approximately 57 million Part D enrollees are in eligible plans.
However, coverage is not automatic. Providers and pharmacists will identify eligible patients, submit the required forms and obtain prior authorization before treatment can begin. Claims, prior authorization requests and pharmacy payments will be handled by Humana, while Part D plans will not be involved in the process.
Eligible beneficiaries will pay a $50 monthly copay for the covered medications.
However, because the program operates outside Medicare Part D coverage:
The pilot program is temporary and is scheduled to end in December 2027, unless it is extended.
"It's certainly good news for Medicare beneficiaries who have been essentially shut out of the market for GLP-1s for weight loss if they wanted to use insurance coverage. However, it is a temporary program. It is not a permanent change in Medicare coverage," said Juliette Cubanski, Vice President and Director of Medicare Policy at KFF.
If the program is not extended, beneficiaries who rely on the medications may have to pay higher out-of-pocket prices or discontinue treatment beginning in January 2028, which experts said could lead to weight regain based on current GLP-1 therapies, the Post reported.

A recent study has found that a modified form of vitamin B12 therapy may prove to be a new and promising way to treat glioblastoma, one of the deadliest and aggressive forms of brain cancer.
With limited treatment options, patients are usually treated with surgery, radiation therapy, and chemotherapy, but the cancer usually returns. Usually, the chance of survival is not bright after diagnosis.
Published in the journal Oncoscience, the research study is based on nitrosylcobalamin (NO-Cbl), a vitamin B12-based compound that contains and slowly releases nitric oxide.
The main purpose of the study was to find out whether the vitamin B-12 compound could cross the blood-brain barrier, a protective layer that prevents many medicines from reaching the brain and directly targeting glioblastoma tumors.
The blood-brain barrier is one of the biggest challenges in treating glioblastoma, as it protects the brain from harmful substances, blocking many cancer drugs from reaching tumor tissue.

The researchers examined how NO-Cbl affected different types of cancer cells, particularly how it moved through the body of rats with glioblastoma. The results showed that NO-Cbl had an anti-cancer effect on several types of tumors.
Most importantly, the compound was able to cross the blood-brain barrier and accumulate inside glioblastoma tumors in animal studies. Researchers also found that the compound remained active in tumor tissue for at least 24 hours, delivering nitric oxide directly to cancer cells without affecting normal tissues.
They also tested NO-Cbl in combination with two existing glioblastoma treatments: temozolomide, the standard chemotherapy drug for the disease, and TRAIL, an experimental cancer therapy.
In laboratory-grown glioblastoma cells, the combinations alleviated cancer cell growth much more effectively than any of the treatments used on their own.

A glioblastoma is a fast-growing glioma, a type of tumor that stems from glial cells, which protect nerve cells in the brain and spinal cord.
Glioblastoma can occur at any age but is more commonly found in older adults. The average age at diagnosis is 64.
Public figures among those afflicted include former President Joe Biden's son, Beau Biden, who succumbed to this cancer in 2015. John McCain also passed away in 2018 due to glioblastoma.
According to the MD Anderson Cancer Center, around 12,000 glioblastoma cases are diagnosed in the United States every year. All glioblastomas are grade IV brain tumors, meaning they contain the most abnormal looking cells and are the most aggressive.
About 13,000 Americans are diagnosed with glioblastoma each year, accounting for almost half of all cancerous brain tumors, according to the Cleveland Clinic. More than 10,000 people in the U.S. will succumb to the disease every year, the National Brain Tumor Society reports.
In the light of limited treatment options for glioblastoma, this study is a ray of hope as it shows promise of slowing down the growth of cancer cells by overcoming challenges like treatment resistance.

Heart failure (HF) remains a major global health challenge, affecting more than 64 million adults worldwide.
To improve how the condition is prevented, diagnosed and managed, leading cardiovascular organizations, including the American Heart Association (AHA) and the American College of Cardiology (ACC), have released the "Second Universal Definition of Heart Failure."
The updated definition addresses changes in disease manifestations, diagnostic strategies and the understanding of heart failure's underlying biology. It also aims to establish a unified framework for clinicians, researchers, health systems and policymakers worldwide.
Published on behalf of the ACC, AHA, European Society of Cardiology (ESC) and World Heart Federation (WHF), in collaboration with the Heart Failure Society of America (HFSA), the Heart Failure Association (HFA) of the ESC and the Japanese Heart Failure Society (JHFS), the document updates the First Universal Definition of Heart Failure, released in 2021. It has been published simultaneously in Circulation, Journal of the American College of Cardiology (JACC), European Heart Journal and Global Heart.
The prevalence of heart failure continues to rise due to ageing populations and increasing rates of obesity, Type 2 diabetes and high blood pressure.
To better address this growing burden, the new framework introduces several important changes.
The revised definition provides a common framework for clinicians, researchers, health systems and policymakers worldwide, helping standardize diagnosis, strengthen research and support more personalized care.
The consensus document will also serve as the foundation for the upcoming American Heart Association/American College of Cardiology Heart Failure Guideline, expected to be published in late 2027.
"Heart failure remains a major challenge that continues to grow globally, and inconsistencies in how it is defined have limited progress in research and treatment. This updated definition provides a clearer, more consistent framework to help clinicians identify risk earlier and guide more personalized treatment approaches that can help improve patient outcomes worldwide," said Mary Norine Walsh, co-chair of the consensus document.
"The new framework recognizes that heart failure is not a static condition. By focusing on stages of disease, underlying causes and disease trajectories—including improvement, remission and recovery—we can better tailor care and advance prevention efforts," she added.
