Considering the potential and pitfalls of "Dr. GPT-3" in a clinic near you
New article assesses natural language computer applications in health care
2021-06-07
(Press-News.org) Artificial intelligence natural language computer applications are becoming increasingly sophisticated, raising the possibility that they could assume a greater role in health care, including interacting with patients. But before these applications enter the clinic, their potential and pitfalls need thoughtful exploration, states a new article in NPJ Digital Medicine.
The authors are Diane M. Korngiebel, a Hastings Center research scholar, and Sean D. Mooney, chief research information officer at University of Washington Medicine.
"There is compelling promise and serious hype in AI applications that generate natural language" Korngiebel and Mooney write, referring to OpenAI's Generative Pre-trained Transformer 3 (GPT-3) and similar technologies. The article breaks down potential health care applications into three categories: unrealistic, realistic and feasible, and realistic but challenging.
Unrealistic Applications
Natural language AI applications will not replace doctors, nurses, and other health care personnel in conversation with patients anytime soon. "Interactions with GPT-3 that look (or sound) like interactions with a living, breathing--and empathetic or sympathetic--human being are not," the authors write. In a recent test of GTP-3 for mental health counseling, for example, the application supported a simulated patient's expressed thoughts of suicide. In addition, natural language AI applications currently reflect human biases involving gender, race, and religion.
Realistic and Feasible Applications
Natural language applications could relieve health care providers of some routine tedious tasks, such as navigating complex electronic health records. And, given that they are capable of fairly natural-sounding question and answer exchanges, the applications could improve customer service online chat support and help patients with noncritical tasks such as setting up equipment in preparation for a telehealth visit. But there must be "serious guardrails" for all health care interactions, including training the applications to eliminate "harmful, prejudicial, or inappropriate vocabulary."
Realistic but Challenging Applications
GTP-3 could be used to assist with triaging noncritical patients who come to emergency departments. However, developers of the technology and people implementing it would need to be mindful of harms. For example, natural language applications that do not "speak" a patient's language might triage that patient inappropriately. "Implementation should include another means of triaging those patients who cannot, or do not wish to, use the conversational agent, which may also be too linguistically homogenous to offer culturally mindful language use," the authors write, adding that it is important to maintain a "human in the loop." A staff member would also need to review all triage forms.
The article concludes with recommendations for making sure that natural language applications are equitable. A broad range of stakeholders should be involved from the earliest stage of development through deployment and evaluation. And there should be transparency, including in the datasets used and limitations of the applications.
"We should have cautious optimism for the potential applications of sophisticated natural language processing applications to improve patient care," the authors write. "The future is coming. Rather than fear it, we should prepare for it--and prepare to benefit humanity using these applications."

LEBANON, NH - Previous work by a team of researchers led by Steven N. Fiering, PhD, Immunology and Cancer Immunotherapy researcher at Dartmouth's and Dartmouth-Hitchcock's Norris Cotton Cancer Center and Nicole Steinmetz, PhD, Jacobs School of Engineering and Moores Cancer Center, University of California San Diego, showed that a plant virus that does not infect mammals, cowpea mosaic plant virus (CPMV), when injected into cancerous tumors, strongly stimulated the immune system to attack and often eliminate the tumor. However, very little was understood about immune recognition of plant viruses and how and why CPMV is exceptionally immuno-stimulating. In a new study, the team identifies ...

Extreme risk protection orders (ERPOs), also known as gun violence restraining orders, are civil court orders that grant temporary restrictions on purchasing and possessing firearms for individuals determined by a civil court judge to be at extreme risk of committing violence against themselves or others. A new study examined ERPO use in Oregon in the first 15 months after it was adopted. The study found that while ERPOs are commonly considered as a tool to remove guns from dangerous individuals, they should also be considered as a tool to prevent gun purchases by dangerous individuals.
The study was conducted by researchers at Michigan State University (MSU), Columbia University, the University of Michigan, and Johns Hopkins University. It appears in ...

The threat of antibiotic resistance rises as bacteria continue to evolve to foil even the most powerful modern drug treatments. By 2050, antibiotic resistant-bacteria threaten to claim more than 10 million lives as existing therapies prove ineffective.
Bacteriophage, or "phage," have become a new source of hope against growing antibiotic resistance. Ignored for decades by western science, phages have become the subject of increasing research attention due to their capability to infect and kill bacterial threats.
A new project led by University of California San Diego Biological Sciences graduate ...

To investigate factors that can jeopardize pregnancy success in cattle, researchers at the University of São Paulo (USP) in Brazil used a kind of chip to mimic the environment of the endometrium, the tissue that lines the inside of the uterus.
The study was conducted by biologist Tiago Henrique Camara de Bem, a postdoctoral fellow at the University of São Paulo's School of Animal Science and Food Engineering (FZEA-USP), in collaboration with four researchers at the University of Leeds in the UK. Their findings are reported in an article in the journal Endocrinology.
The researchers focused on analyzing alterations in levels of insulin and glucose in maternal ...

CAMBRIDGE, MA -- About 60 percent of drugs on the market have hydrophobic molecules as their active ingredients. These drugs, which are not soluble in water, can be difficult to formulate into tablets because they need to be broken down into very small crystals in order to be absorbed by the human body.
A team of MIT chemical engineers has now devised a simpler process for incorporating hydrophobic drugs into tablets or other drug formulations such as capsules and thin films. Their technique, which involves creating an emulsion of the drug and then crystallizing it, allows for a more powerful dose to be loaded per tablet.
"This is very important because if we can achieve high drug loading, it means that we can ...

ITHACA, N.Y. - As soon as an ear of corn is taken off its stalk or a potato is pulled from the ground, it travels anywhere from a few miles to across continents and sometimes undergoes processes that transform it into the food we consume.
These miles and processes contribute to what's known as the food value chain (FVC), along which, as one might expect, the value of the product increases. However, most of the research and attention thus far paid to FVCs occurs at the ends of the chain - inside the farm gate and at the consumer's plate.
Less is understood about all of the other links in the FVC, in part due to a lack of ...

In the quest for healthy aging and longer lifespan, Danish researchers at the University of Southern Denmark have collaborated with Swedish researchers at Karolinska Institutet to explore the anti-aging effects of football and team handball training in women.
In a current study published in Scientific Reports, the researchers investigated the effects of lifelong regular exercise on two of the central hallmarks of aging combined and showed that football and team handball have a positive effect on telomere length and mitochondrial function in women.
"Our legacy consists of DNA that is packed in chromosomes. When cells divide, the inheritance is copied, but with each cell division the ends of the DNA threads get shorter. The so-called telomeres are shortened, which causes us to age. ...

High blood pressure, or hypertension, is the leading modifiable risk factor for cardiovascular diseases and premature death worldwide. And key to treating patients with conditions ranging from chest pain to stroke is understanding the intricacies of how the cells around arteries and other blood vessels work to control blood pressure. While the importance of metals like potassium and calcium in this process are known, a new discovery about a critical and underappreciated role of another metal - zinc - offers a potential new pathway for therapies to treat hypertension.
The study results were published recently in Nature Communications.
All the body's functions depend on arteries channeling oxygen-rich ...

The COVID-19 pandemic continues to disrupt and end lives around the world, and public health officials worldwide have recognized vaccines as the critical tools required for controlling the COVID-19 death toll and achieving a return to normal life. Several vaccines against COVID-19 are already in use, but the limited supplies of these vaccines and the possibility of safety and efficacy issues of the existing vaccines mean that it is important for scientists to develop more (and even better) vaccines. In fact, as of February 2021, 69 different vaccines are in various phases of clinical development.
One type of vaccine that could prove quite useful is the inactivated vaccine, which contains an inactivated form of the virus. The inactivated virus cannot harm the recipient, but ...
