AI Revolution in Healthcare: Podcast Transcript

Welcome to “AI Unraveled: Demystifying Frequently Asked Questions on Artificial Intelligence, Latest AI Trends,” where we dive deep into the complexities of AI and bring forth the latest developments in an easy-to-understand format. Today, we’re tackling a series of compelling updates from the AI frontier in the medical field and beyond. In a remarkable medical application, GPT-4, OpenAI’s newest language model, has been put to the test by Dr. Isaac Kohane of Harvard. Impressively, GPT-4 has been reported to perform better than many human doctors, correctly answering medical exam questions over 90% of the time. But what’s truly astonishing is its ability to diagnose a rare 1 in 100,000 condition in just seconds, a task that draws upon the depth of a seasoned physician’s experience. Despite these advances, Dr. Kohane’s book, ‘The AI Revolution in Medicine,’ brings us back to earth, reminding us that GPT-4 is not infallible, presenting a balanced view with examples of the model’s errors ranging from minor clerical issues to math mistakes.

hifting gears, we look at how pharmaceutical giant Moderna and tech behemoth IBM are joining forces to push the boundaries of mRNA technology. Their collaboration intends to combine generative AI and quantum computing, potentially accelerating the discovery of new therapies and vaccines. This is underpinned by using IBM’s MoLFormer, which is expected to enhance Moderna’s understanding of mRNA medicines. In a leap toward precision medicine, Google Cloud has recently launched two AI-powered tools geared at revolutionizing drug discovery. These innovative tools focus on predicting protein structures and managing vast amounts of genomic data, potentially shaving off years in drug development time. We also witness the rise of BiomedGPT, touted as one of the most sophisticated AI medical models, outperforming predecessors across multiple biomedical modalities. This model appears to be a game-changer with its multi-modal and multi-task learning capabilities.

The competition intensifies in the healthcare AI space with Google’s Med-PaLM 2 going through testing at the Mayo Clinic, while Microsoft swiftly incorporates AI advances into patient care by deploying GPT algorithms via cloud services. Furthermore, MedPerf emerges as a new beacon, an open benchmarking platform introduced by MLCommons, aimed to evaluate medical AI models on diverse datasets, prioritizing patient privacy and aiming to enhance AI’s generalizability in healthcare. Adding to an already impressive array of advancements, we have AlphaMissense by Google DeepMind, which is honing the ability to predict genetic diseases, and Google Cloud briefing the healthcare sector with new capabilities to sift through clinical data more efficiently. And finally, EVEscape, a new AI tool with the potential to predict future viral variants—imagine its profound implications had it been available at the onset of the COVID-19 pandemic!

To cap off, studies suggest that AI models like ChatGPT can outdo doctors in providing unbiased treatment recommendations for depression and that AI algorithms are increasingly crucial in cellular research, changing the landscape of biological imaging experiments. Before we conclude, let’s not forget about AMIE, Google’s Articulate Medical Intelligence Explorer, an AI system optimized for diagnostic reasoning that is giving medical professionals a run for their money. For those seeking a deeper understanding of these advancements, the book “AI Unraveled: Master GPT-4, Gemini, Generative AI & LLMs – Simplified Guide for Everyday Users: Demystifying Artificial Intelligence – OpenAI, ChatGPT, Google Bard, AI ML Quiz, AI Certifications Prep, Prompt Engineering,” is available on various platforms including Etsy, Shopify, Apple, Google, and Amazon. That brings us to the end of today’s episode. We hope you’ve gained new insights into the dynamic and revolutionary world of AI, especially its influence on healthcare. Join us next time on “AI Unraveled” as we continue to explore cutting-edge AI trends that are transforming our lives. Till then, this is your host signing off. Keep questioning, keep learning, and remember—the future is AI.

GPT-4 diagnosed a 1 in 100,000 condition in seconds

Dr. Isaac Kohane, a physician and computer scientist at Harvard, has tested the newest AI model, GPT-4, in a medical setting. According to his findings, GPT-4 performs better than many doctors, as it can answer medical exam licensing questions correctly more than 90% of the time, translate information for patients, and give doctors helpful suggestions about bedside manner.

Kohane tested GPT-4 on a real-life case and found that it could correctly diagnose a rare condition just as he would with all his years of experience. However, GPT-4 isn’t always reliable, and his latest book ‘The AI Revolution in Medicine’ is filled with examples of its blunders, ranging from clerical errors to math mistakes.

Moderna, IBM to explore Generative AI and quantum computing for mRNA vaccines

Moderna and IBM are partnering to advance mRNA technology using generative AI and quantum computing, which could speed up Moderna’s discovery and creation of new messenger RNA vaccines and therapies. Moderna’s scientists will have access to IBM’s generative AI model known as MoLFormer, which will help understand the characteristics of potential mRNA medicines and design a new class of vaccines and therapies.

This agreement comes as Moderna is trying to harness its mRNA technology to target other diseases, while IBM is ramping up its investment in AI with new partnerships, largely driven by the release of OpenAI’s ChatGPT.

Why does this matter?

The use of quantum computing and AI could help Moderna accelerate the discovery and creation of these new vaccines and therapies by solving problems too complex for traditional computers. The development of these new medicines could potentially benefit the general public by providing more treatment options for a range of diseases.

AI model outperforms traditional methods in identifying cancerous nodules

An AI model developed by experts at the Royal Marsden NHS foundation trust, the Institute of Cancer Research, London, and Imperial College London can accurately identify cancer, potentially speeding up diagnosis and treatment. The algorithm, which analyzes CT scans to determine if abnormal growths are cancerous, reportedly performs more efficiently and effectively than current methods.

Why does this matter?

The AI tool may help doctors make faster decisions about patients with abnormal growths that are currently deemed medium-risk. The model, which is still in its early stages, will require further testing before it can be introduced in healthcare systems. However, researchers hope the AI tool will eventually speed up cancer detection by fast-tracking patients to treatment.

AI can detect signs of Alzheimer’s even before symptoms begin to show

Researchers at UT Southwestern Medical Center have found that AI-powered voice analysis can help diagnose Alzheimer’s and cognitive impairment in early stages. If confirmed by larger studies, these findings could primary care providers with an easy-to-perform screening tool for at-risk individuals.

The research used advanced ML and natural language processing (NLP) to identify even the subtlest changes in language and audio that individuals may not easily recognize.

Why does this matter?

Before ML and NLP, detailed speech studies were often unsuccessful as early changes were often undetectable to human ears. However, with advancements in AI, such novel testing methods have performed significantly better than standard cognitive assessments in detecting even mild impairments. Also, it took less than 10 minutes to capture a patient’s voice, outdoing the traditional tests, which took hours to administer.

Only a few days ago, researchers developed an AI model that outperformed traditional methods in identifying cancer. Does this indicate AI leading the charge in reducing overall healthcare costs with improved patient outcomes?

DeepMind’s new AI can predict genetic diseases

Google DeepMind’s new system, called AlphaMissense, can tell if the letters in the DNA will produce the correct shape. If not, it is listed as potentially disease-causing.

Currently, genetic disease hunters have fairly limited knowledge of which areas of human DNA can lead to disease and have to search across billions of chemical building blocks that make up DNA. They have classified 0.1% of letter changes, or mutations, as either benign or disease-causing. DeepMind’s new model pushed that percentage up to 89%.

Why does this matter?

AI is changing nearly everything we do at the moment and might revolutionize molecular biology and life sciences, too. This development is expected to speed up diagnosis and help search for better genetic disease treatments.
