I feel like I’ve been writing a lot about the future that I’m very worried about, so I’m glad there are some developments to talk about which helps me remind me that technology is cool and that healthcare can certainly use more.
First is a new AI algorithm called Faceage, last week Lancet Digital Health By General Mass Researchers. Its purpose is to use photos to determine the age of the organisms, rather than to arrange their ages in chronological order. We all know that different people seem to age at different rates – I mean, how old is Paul Rud? ? ? – But the connection between people’s appearance and health is intuitive at best.
In addition, the algorithm can help determine survival outcomes for various types of cancer.
The researchers trained the algorithm on nearly 59,000 photos in the public database and then tested the photos of 6,200 cancer patients taken before radiation therapy began. Cancer patients appear to be about five years older than their age. “We can use artificial intelligence (AI) to estimate a person’s biological age from facial images, and our research shows that information is clinically meaningful,” said Dr. Hugo Aerts, a collaborator and corresponding author of the Mass Mass Brigham Medicine Intelligne Intelligence (AIM) program.
Strangely, the algorithm doesn’t seem to care whether someone is bald or gray-haired, and may use more subtle cues, such as muscle sounds. It is not clear what the difference between makeup, lighting or plastic surgery is. “This is something we are actively investigating and researching,” Dr. Elter told Washington Post. “We are now testing in various data sets [to see] How we make the algorithm strong about this. ”
Furthermore, it is mainly trained on white faces, which researchers believe is a deficiency. Jennifer E. Miller, co-director of Yale’s Biomedical Ethics Program, told Yale that I’m very worried about the effect of the tool for all populations such as women, older people, race and minorities, people with all kinds of disabilities, pregnant women, and more. ” The New York Times.
The researchers believe that couples can be used to better estimate survival rates in cancer patients. It turns out that when doctors try to look at them simply, their guesses are essentially like throwing a coin. When paired with Faceage’s insights, the accuracy can reach about 80%.
“This work shows that photos like a simple selfie contain important information that can help you provide clinical decision-making and care plans for patients and clinicians. It is actually important to be how old someone is compared to age – the age after cancer treatment is younger, younger, and older after cancer treatment.”
I was particularly excited about this because ten years ago I speculated using selfies and facial recognition AI to determine if we have premature aging, or even we are just sick. It seems that the large-scale Brigham Young researchers agreed. “This creates a completely new field of biomarker discovery for photos that extends far beyond cancer care or predicted age,” said Ray Mak, MD, a faculty member of the Mass Brigham AIM program. “As we increasingly view different chronic diseases as a disease of aging, it becomes even more important to be able to accurately predict an individual’s aging trajectory. I hope we can ultimately use this technology as an early detection system in a variety of applications within a strong regulatory and ethical framework to help save lives.”
Researchers acknowledge that a lot must be achieved before it is introduced for commercial purposes and strong oversight is required to ensure that as Dr. Aerts told wapo“These AI technologies are used in the right way, really just to benefit patients,” as Daniel Belsky, an epidemiologist at Columbia University, told The New York Times:: “We are in a long way to go where we are today and actually using these tools in a clinical setting.”
The second development is even more. Let me break it down California Institute of Technology News title:””3D printing. “Okay, you have my attention.”in vivo. ”I am very interested.Using sound. “shock.
that’s right. The researchers “developed a method for 3D printing polymers at specific locations deep in living creatures.”
Apparently, 3D printing has been performed in the body before, but using infrared light. “But infrared permeability is very limited. It only reaches under the skin,” said Wei Gao, professor of medical engineering and corresponding author of Caltech. “Our new technology reaches deep tissue and can print a variety of materials for a wide range of applications while maintaining excellent biocompatibility.”
They call the technology a deep tissue in vivo sound printing (DISP) platform.
“Distribution technology provides a multifunctional platform for printing a wide range of functional biomaterials, unlocking bioelectronics, drug delivery, tissue engineering, wound sealing and later applications,” the team said. “Through precise control of material properties and spatial resolution, distribution is ideal for creating functional structures and patterns directly in biological tissue.”
The authors concluded: “DESP’s ability to print conductive, drug-loaded, cell-rich and bioadhesive biomaterials demonstrates its versatility for a variety of biomedical applications.”
I will provide you with detailed information about ultrasound and cryosensitive liposomes. The key point is: “We have shown in a small animal that can print a hydrogel with a drug for tumor treatment,” Dr. Gao said. “Our next phase is trying to print in larger animal models, and hopefully in the near future we can evaluate this in humans… In the future, with the help of AI, we hope to be able to autonomously trigger high-precision printing in mobile organs such as Beating Heart.”
Dr. Gao also pointed out that not only can Bio-Ink be added if needed, but it can be deleted when needed. In contrast, minimally invasive surgery seems rough.
“It’s exciting,” Zhang Zhang, a biomedical engineer at Harvard Medical School and biomedical engineer at Brigham Young and Women’s Hospital, told him that he was not involved in the study. IEEE spectrum. “This work does expand the scope of ultrasound-based printing and shows its translation capabilities.”
First author Elham Davoodi has high hopes. “This is very general…This is a new research direction in the field of bioprinting.”
“Very exciting” is not fair.
During these passionate days we have to find solace where we can, and these are things that make me hope for the future.
