Health: “Smart Hospitals” Using AI & Sensors Could Reduce Thousands Of Deaths Yearly (Stanford)
As many as 400,000 Americans die each year because of medical errors, but many of these deaths could be prevented by using electronic sensors and artificial intelligence to help medical professionals monitor and treat vulnerable patients in ways that improve outcomes while respecting privacy.
The Fix: Invisible light guided by AI?
Haque, who compiled the 170 scientific papers cited in the Nature article, said the field is based largely on the convergence of two technological trends: the availability of infrared sensors that are inexpensive enough to build into high-risk care-giving environments, and the rise of machine learning systems as a way to use sensor input to train specialized AI applications in health care.
These alert systems are being tested to see if they can reduce the number of ICU patients who get nosocomial infections — potentially deadly illnesses contracted by patients due to failure of other people in the hospital to fully adhere to infection prevention protocols.
Constant monitoring by ambient intelligence systems in a home environment could also be used to detect clues of serious illness or potential accidents, and alert caregivers to make timely interventions. For instance, when frail seniors start moving more slowly or stop eating regularly, such behaviors can presage depression, a greater likelihood of a fall or the rapid onset of a dangerous health crisis. Researchers are developing activity recognition algorithms that can sift through infrared sensing data to detect changes in habitual behaviors, and help caregivers get a more holistic view of patient well-being.
Stanford: Researchers Find Way To “Regrow” New Cartilage In Joints
The Stanford researchers figured out how to regrow articular cartilage by first causing slight injury to the joint tissue, then using chemical signals to steer the growth of skeletal stem cells as the injuries heal. The work was published Aug. 17 in the journal Nature Medicine.
“Cartilage has practically zero regenerative potential in adulthood, so once it’s injured or gone, what we can do for patients has been very limited,” said assistant professor of surgery Charles K.F. Chan, PhD. “It’s extremely gratifying to find a way to help the body regrow this important tissue.”
STANFORD MEDICINE (Aug 17, 2020): Researchers at the Stanford University School of Medicine have discovered a way to regenerate, in mice and human tissue, the cushion of cartilage found in joints.
Loss of this slippery and shock-absorbing tissue layer, called articular cartilage, is responsible for many cases of joint pain and arthritis, which afflicts more than 55 million Americans. Nearly 1 in 4 adult Americans suffer from arthritis, and far more are burdened by joint pain and inflammation generally.
Art Centers: Sculptor Auguste Rodin’s Enduring Appeal (Stanford Cantor)
Stanford University (July 20, 2020):
What makes Rodin’s sculptures “modern”?
The enduring appeal of Rodin, the modernity of his work, has to do with the way in which he makes visible an aesthetic of process – how, in other words, he takes traditional sculpture apart and puts it back together again in new and daring ways. Strategies of multiplication, scalability, fragmentation and recombinatory modes of assembly and display constitute some of the hallmarks of Rodin’s artistic practice.
Works by Rodin on view at the Cantor are often utilized by students and scholars from a range of disciplines, including medicine. In this moment, with outbreak of disease across the globe, what can Rodin’s works teach us about the relationship between art and nature?
It’s interesting that Rodin attracts so much attention from medical experts, especially here at Stanford, who have used his hands for diagnostic purposes. It’s true that Rodin was intensely interested in exploring pathologies of the body, especially now-discredited understandings of female hysteria. But there is also the irony that Rodin became furious after a critic accused him of making his first life-size figure through life casting, rather than modeling it himself. It should go without saying, but Rodin’s hands are not hands – not real ones, anyway – and their expressive forms don’t align neatly with the anatomical reality of hands in flesh and blood or even their more naturalistic counterparts. But the very fact that they elicit such responses demonstrates the power of art to provoke challenging questions that drive innovative paths of research that cut across disciplines, particularly in a university setting.
Tributes: Sleep Medicine Pioneer William Dement Dies At 91 – “Drowsiness Is Red Alert” (1928 – 2020)
His mission was to educate the world about the importance of sleep, which he believed was dangerously undervalued. His motto, “drowsiness is red alert,” is a message he tirelessly broadcast to his students, trainees, members of Congress and the world at large.
William Dement, MD, PhD, known as the father of sleep medicine, died June 17 after a two-year battle with cardiovascular disease. He was 91.
With a handful of other scientists, Dement, a longtime faculty member of the Stanford School of Medicine, created the fields of sleep research and sleep medicine, and his many books and lectures helped raise awareness of sleep disorders and the dangers of sleep deprivation.
Dement’s many other accomplishments and accolades range far and wide: Dement and Guilleminault were the founding editors of the journal Sleep, the first major international journal devoted to sleep, publishing the first issue in 1978. He was the author of books for lay readers, including The Promise of Sleep, Some Must Watch While Some Must Sleep and The Sleepwatchers. The 2012 comedy film Sleepwalk with Me featured The Promise of Sleep and Dement in a cameo.
2020 Innovation: “Remote-Only Organizations”: Is This The Future Of Work?
From a Stanford Engineering article (April 8, 2020):
Companies that structure themselves as location-independent have developed norms and practices that bridge the emotional and logistical distances. The same is true for their workers. For such companies, remote-only work can reduce costs, expand the talent pool and boost productivity. By contrast, being forced by a crisis to work remotely is likely to be disruptive and frustrating. It may be better than shutting down, but it will likely lead to a big drop in productivity.
In the span of a single month, the COVID-19 pandemic has forced companies and organizations of all types to have almost all of their employees work remotely from home.
Has the future of work, the all-remote workforce and even the virtual organization, arrived in full force? Though online technologies have made remote work increasingly common, most companies and organizations are still run out of brick-and-mortar facilities. Now they are scrambling to stand up virtual workspaces overnight.
Health: All Adults 18-79 Should Be Screened For Hepatitis C Virus (HCV)
From a Stanford University online article (March 2, 2020):
“The opioid epidemic has added fuel to the HCV fire, substantially increasing transmission,” said Owens. “HCV is now an enormous public health problem, affecting a much broader age range of people than before. Fortunately, we have the tools to identify people and treatment is now successful in the vast majority of patients, so screening can prevent the mortality and morbidity from HCV.”
A task force of national health experts recommends clinicians screen all adults 18 to 79 for the hepatitis C virus (HCV), noting that the viral infection is now associated with more deaths in the United States than the top 60 reportable infectious diseases combined. Many people are unaware they are carrying the viral infection.
“People with hepatitis C do not always feel sick and may not know they have it,” says chair of the U.S. Preventive Services Task Force Douglas K. Owens, M.D, M.S. “Screening is key to finding this infection early, when it’s easier to treat and cure, helping reduce illnesses and deaths.”
Owens, who is the director of Stanford Health Policy and the Henry J. Kaiser, Jr., Professor of Medicine, said the opioid epidemic now plays an important role in the prevalence of HCV. There are more than three times the number of acute HCV cases than a decade ago, particularly among young, white, injection drug users who live in rural areas. Women aged 15 to 44 have also been hit hard by the virus that is spread through contaminated blood.
Health Talk: Stanford Dermatology Professor Eleni Linos On “Tanning Bed” Cancer Research
“Studies with financial links to the indoor tanning industry were much more likely to discuss perceived benefits of indoor tanning and to downplay the harms,” said Eleni Linos, MD, DrPH, professor of dermatology, who sees patients at Stanford Health Care’s dermatology clinic at the Hoover Pavilion. “The association is quite striking. We need scientific data to be independent of industry influence. I am concerned that funding sources may influence the conclusions of these papers.”
In 2012, Eleni Linos, professor of dermatology at Stanford university, published a systematic review and meta-analysis of the link between non-melanoma cancer and sun-beds. That bit of pretty standard research, and a particular rapid response to it, has kicked of years of work – and in this podcast I talk to Eleni and her colleagues Stanton…

Research: Omega-3 Fatty Acids In Diet Promotes Health By Limiting Large Fat Cell Accumulation
From a Stanford Medicine online news release:
“What you want is more, small fat cells rather than fewer, large fat cells,” Jackson said. “A large fat cell is not a healthy fat cell. The center is farther away from an oxygen supply, it sends out bad signals and it can burst and release toxic contents.” Large fat cells are associated with insulin resistance, diabetes and inflammation, he added.
Jackson and his colleagues found that when omega-3 fatty acids bind to a receptor called FFAR4 on the cilia of fat stem cells, it prompts the fat stem cells to divide, leading to the creation of more fat cells. This provides the body with more fat cells with which to store energy, something that is healthier than storing too much fat in existing fat cells.
For years, researchers have known that defects in an ancient cellular antenna called the primary cilium are linked with obesity and insulin resistance. Now, researchers at the Stanford University School of Medicine have discovered that the strange little cellular appendage is sensing omega-3 fatty acids in the diet, and that this signal is directly affecting how stem cells in fat tissue divide and turn into fat cells.
