Alzheimer’s Researchers Under Fire: Acclaimed Journalist Explains Why

How reliable is the current research into the cause of Alzheimer’s disease? Award-winning author Charles Piller’s new book is “Doctored: Fraud, Arrogance, and Tragedy in the Quest to Cure Alzheimer's”; it’s raising important questions about certain images that may have been manipulated to bolster the amyloid hypothesis as the cause of Alzheimer’s.

Piller tells “Conversations on Health Care” that “what you have are a multitude of images — not just in Alzheimer’s disease but in many other areas — that have slipped through, that have not been well-examined, and that are, in fact, falsified, or appear to be falsified,” adding that closer scrutiny of images could spur scientists “to re-examine whether the experiments themselves are worth publishing.”

Piller couches this by noting that misconduct occurs in “a small percentage” of research and “does not represent the vast bulk” of work in the field. But a greater emphasis on checks and balances is needed, he says.

Hosts Mark Masselli and Margaret Flinter also ask Piller to respond to criticism of his reporting as well as explain other potential sources of hope in the research field. For instance, clinical trials may reveal, as early as next year, the possible impact of GLP-1 inhibitors — medications developed for obesity and diabetes — on Alzheimer’s. Another theory examines the effect of latent viruses, such as herpes, on the brain.

Egg Prices Up: Hear From Experts About Why

$4.95 — that’s the record high price of a dozen of Grade A eggs in U.S. cities. Michael Osterholm, Ph.D., the director of the Center for Infectious Disease Research and Policy, says expect them to go even higher.

That’s because H5N1, a form of bird flu, has affected more than 156 million commercial, backyard and wild birds in the United States in the last three years.

Osterholm, with nearly 50 years of experience investigating infectious disease outbreaks, emphasizes the urgent need for improved pandemic preparedness. “It’s not a question of if, but when the next major outbreak will happen. Whether it’s a more contagious strain of COVID-19, the bird flu or a completely new virus, we need systems in place now to protect public health and save lives.”

He joins Apoorva Mandavilli, the science and global health reporter with The New York Times, to explore the critical lessons learned from COVID-19 and what must be done to prepare for future public health threats. “Bird flu may seem like a distant problem, but the global nature of infectious diseases means we’re all connected,” Mandavilli says. She also notes that public trust plays a crucial role in mitigating future pandemics. “Without transparency and clear communication, public health measures are far less effective.”

Conversations on Health Care hosts Mark Masselli and Margaret Flinter also ask them how public health agencies must adapt, improve transparency and build global cooperation to combat future outbreaks.

NEJM’s 1st AI Editor on Tech’s Pluses & Minuses

As the year begins, some patients remain concerned about how far artificial intelligence (AI) is creeping into the exam room. But AI has been part of health care longer than most realize, according to Dr. Isaac Kohane, a Harvard University professor.

Kohane is the editor-in-chief of the New England Journal of Medicine’s first publication devoted to AI; it’s a groundbreaking role and we’re proud to share an encore presentation of the interview. He told hosts Mark Masselli and Margaret Flinter that “In the 1980s, automated interpretation of an [echocardiogram] would have been considered AI. Now it’s the ability to look through a patient’s record and come up with a differential diagnosis, a second opinion, a therapeutic plan.”

Kohane shared a success story of a mother whose child had difficulty walking and chewing, suffered from headaches and had seen more than a dozen doctors over many years, with no diagnosis. After one doctor recommended a psychiatric course of action, the mother fed the reports from various past medical visits into a generative AI program, which provided an accurate diagnosis: tethered cord syndrome.

Cases like this can represent AI’s potential, said Kohane. But the nascent technology raises issues of bias. “You can run tests on these AI programs and say, ‘Would you propose that diagnosis more often if this was an African-American or an Indian-American?’ … And you can adjust these programs,” Kohane says. The exciting part is that the adjustment would be easier than undoing even unconscious bias among hundreds of thousands of health care professionals, he explained.

What Elon Musk & Peter Thiel Invest In to Make Lives Longer

Billionaires who dream of extending human life, including Elon Musk, believe they will have very supportive partners in the incoming Trump administration. They’re excited that President Trump has nominated Jim O’Neill for the number two spot at the U.S. Dept. of Health and Human Services because of his history in the anti-aging movement.

David Gobel, the co-founder and CEO of the Methuselah Fund, says, “Jim O’Neill really understands the value of avoiding the suffering…of diseases that don’t actually have to happen if aging is held back. Robert F. Kennedy, Jr., and other nominees are very much in line with the idea of holding aging back by whatever means.” President Trump has nominated Kennedy to serve as HHS secretary.

But “Conversations on Health Care” recently spoke with S. Jay Olshansky, Ph.D., a professor at the University of Illinois at Chicago, who questioned private and public dollars going to such efforts. “We’ll be lucky if 5% of the age cohort makes it to 100,” he said. Olshansky and his colleagues have presented data that humans are approaching a biologically-based limit to life.

Join hosts Mark Masselli and Margaret Flinter for this look into the world of life extension and how Trump administration officials could push the country to embrace these unconventional practices. In addition, learn more about the first longevity patient protocol from Danielle Ruiz, MSN, APRN, AGNP-C, CEO and Medical Director, Everest Health.

Nurse Practitioners: A Growing Opportunity

Nurse practitioners, at 385,000 strong in the U.S., are increasingly seen as a key part of the solution to the primary care provider shortage. What are the challenges and opportunities to ensure everyone can get the care they need when they need it? Our guest is the president of the American Association of Nurse Practitioners, Stephen Ferrara, DNP. He also serves as the inaugural associate dean of artificial intelligence and a professor of nursing at the Columbia University School of Nursing.

Hosts Mark Masselli and Margaret Flinter (who has been a family nurse practitioner for many years) discuss the opportunities for Ferrara and his members as they seek to expand what’s called “scope of practice.” In fact, the percentage of medical visits handled by health care providers other than physicians nearly doubled between 2013 and 2019, with many of those patients seen by nurse practitioners.
