On December 3, a federal appeals court ruled against one of the FDA’s untouchable restrictions on industry—thou shalt not promote the off-label use of pharmaceutical products. An industry that is little interested in constitutional law suddenly finds itself talking about the First Amendment and whether, and on what grounds, the case will be appealed. Meantime, the court’s decision left FDA Matters torn between cheering and booing. Patients are poorly served if their doctor is prescribing drugs without being able to tap into all sources of relevant knowledge. However, permitting off-label promotion undercuts the incentive for companies to thoroughly investigate the safety and efficacy of a drug for a second or third use.

Looking back over the last 40 years at FDA (as I have), there are three characteristics that create a more progressive environment at the agency: continuity of leadership, presidential support, and increased funding. For FDA in 2013 (as the saying goes): 2 out of 3 ain’t bad. In particular, medical innovation seems poised to flourish in an FDA environment where there is continuity of policy and leadership, instead of a new team learning the ropes. I explore this and other themes in the latest issue of Pharmaphorum.com.

Magnetic resonance imaging (MRI) has revolutionized healthcare by providing radiation-free, non-invasive 3-D medical images. However, MRI scanners often consume 25 kilowatts or more to power magnets producing magnetic fields up to 1.5 tesla. These requirements typically limits scanners’ use to specialized centers and departments in hospitals.

A University of Hong Kong team has now unveiled a low-power, highly simplified, full-body MRI device. With the help of artificial intelligence, the new scanner only requires a compact 0.05 T magnet and can run off a standard wall power outlet, requiring only 1,800 watts during operation. The researchers say their new AI-enabled machine can produce clear, detailed images on par with those from high-power MRI scanners currently used in clinics, and may one day help greatly improve access to MRI worldwide.

To generate images, MRI applies a magnetic field to align the poles of the body’s protons in the same direction. An MRI scanner then probes the body with radio waves, knocking the protons askew. When the radio waves turn off, the protons return to their original alignment, transmitting radio signals as they do so. MRI scanners receive these signals, converting them into images.

More than 150 million MRI scans are conducted worldwide annually, according to the Organization for Economic Cooperation and Development. However, despite five decades of development, clinical MRI procedures remain out of reach for more than two-thirds of the world’s population, especially in low- and middle-income countries. For instance, whereas the United States has 40 scanners per million inhabitants, in 2016 there were only 84 MRI units serving West Africa’s population of more than 370 million.

This disparity largely stems from the high costs and specialized settings required for standard MRI scanners. They use powerful superconducting magnets that require a lot of space, power, and specialized infrastructure. They also need rooms shielded from radio interference, further adding to hardware costs, restricting their mobility, and hampering their availability in other medical settings.

Scientists around the globe have already been exploring low-cost MRI scanners that operate at ultra-low-field (ULF) strengths of less than 0.1 T. These devices may consume much less power and prove potentially portable enough for bedside use. Indeed, as the Hong Kong team notes, MRI development initially focused on low fields of about 0.05 T, until the introduction of the first whole-body 1.5 T superconducting scanner by General Electric in 1983.

Current ULF MRI scanners often rely on AI to help reconstruct images from what signals they gather using relatively weak magnetic fields. However, until now, these devices were limited to solely imaging the brain, extremities, or single organs, Udunna Anazodo, an assistant professor of neurology and neurosurgery at McGill University in Montreal who did not take part in the work, notes in a review of the new study.

The Hong Kong team have now developed a whole-body ULF MRI scanner in which patients are placed between two permanent neodymium ferrite boron magnet plates—one above the body and the other below. Although these permanent magnets are far weaker than superconductive magnets, they are low-cost, readily available, and don’t require liquid helium or to be cooled to superconducting temperatures. In addition, the amount of energy ULF MRI scanners deposit into the body is roughly one-thousandth that from conventional scanners, making heat generation during imaging much less of a concern, Anazodo notes in her review. ULF MRI is also much quieter than regular MRI, which may help with pediatric scanning, she adds.

The new machine consists of two units, each roughly the size of a hospital gurney. One unit houses the MRI device, while the other supports the patient’s body as it slides into the scanner.

To account for radio interference from both the outside environment and the ULF MRI’s own electronics, the scientists deployed 10 small sensor coils around the scanner and inside the electronics cabinet to help the machine detect potentially disruptive radio signals. They also employed deep learning AI methods to help reconstruct images even in the presence of strong noise. They say this eliminates the need for shielding against radio waves, making the new device far more portable than conventional MRI.

In tests on 30 healthy volunteers, the device captured detailed images of the brain, spine, abdomen, heart, lung, and extremities. Scanning each of these targets took eight minutes or less for image resolutions of roughly 2 by 2 by 8 cubic millimeters. In Anazodo’s review, she notes the new machine produced image qualities comparable to those of conventional MRI scanners.

“It’s the beginning of a multidisciplinary endeavor to advance an entirely new class of simple, patient-centric and computing-powered point-of-care diagnostic imaging device,” says Ed Wu, a professor and chair of biomedical engineering at the University of Hong Kong.

The researchers used standard off-the-shelf electronics. All in all, they estimate hardware costs at about US $22,000. (According to imaging equipment company Block Imaging in Holt, Michigan, entry-level MRI scanners start at $225,000, and advanced premium machines can cost $500,000 or more.)

The prototype scanner’s magnet assembly is relatively heavy, weighing about 1,300 kilograms. (This is still lightweight compared to a typical clinical MRI scanner, which can weigh up to 17 tons, according to New York University’s Langone Health center.) The scientists note that optimizing the hardware could reduce the magnet assembly’s weight to about 600 kilograms, which would make the entire scanner mobile.

The researchers note their new device is not meant to replace conventional high-magnetic-field MRI. For instance, a 2023 study notes that next-generation MRI scanners using powerful 7 T magnets could yield a resolution of just 0.35 millimeters. Instead, ULF MRI can complement existing MRI by going to places that can’t host standard MRI devices, such as intensive care units and community clinics.

In an email, Anazodo adds this new Hong Kong work is just one of a number of exciting ULF MRI scanners under development. For instance, she notes that Gordon Sarty at the University of Saskatchewan and his colleagues are developing that device that is potentially even lighter, cheaper and more portable than the Hong Kong machine, which they are researching for use in whole-body imaging on the International Space Station.

Wu and his colleagues detailed their findings online 10 May in the journal Science.

UPDATE 31 OCTOBER 2024: No. 1 no longer. The would-have-been groundbreaking study published in Nature Communications by Amit Goyal et al. claiming the world’s highest-performing high-temperature superconducting wires yet has been retracted by the authors.

The journal’s editorial statement that now accompanies the paper says that after publication, an error in the calculation of the reported performance was identified. All of the study’s authors agreed with the retraction.

The researchers were first alerted to the issue by Evgeny Talantsev at the Mikheev Institute of Metal Physics in Ekaterinburg, Russia, and Jeffery Tallon at the Victoria University of Wellington in New Zealand. In a 2015 study, the two researchers had suggested upper limits for thin-film superconductors, and Tallon notes follow-up papers showed these limits held for more than 100 known superconductors. “The Goyal paper claimed current densities 2.5 times higher, so it was immediately obvious to us that there was a problem here,” he says.

Upon request, Goyal and his colleagues “very kindly agreed to release their raw data and did so quickly,” Tallon says. He and Talantsev discovered a mistake in the conversion of magnetization units.

“Most people who had been in the game for a long time would be fully conversant with the units conversion because the instruments all deliver magnetic data in [centimeter-gram-second] gaussian units, so they always have to be converted to [the International System of Units],” Tallon says. “It has always been a little tricky, but students are asked to take great care and check their numbers against other reports to see if they agree.”

In a statement, Goyal notes he and his colleagues “intend to continue to push the field forward” by continuing to explore ways to enhance wire performance using nanostructural modifications. —Charles Q. Choi

Original article from 17 August, 2024 follows:

Superconductors have for decades spurred dreams of extraordinary technological breakthroughs, but many practical applications for them have remained out of reach. Now a new study reveals what may be the world’s highest-performing high-temperature superconducting wires yet, ones that carry 50 percent as much current as the previous record-holder. Scientists add this advance was achieved without increased costs or complexity to how superconducting wires are currently made.

Superconductors conduct electricity with zero resistance. Classic superconductors work only at super-cold temperatures below 30 degrees Kelvin. In contrast, high-temperature superconductors can operate at temperatures above 77 K, which means they can be cooled to superconductivity using comparatively inexpensive and less burdensome cryogenics built around liquid nitrogen coolant.

Regular electrical conductors all resist electron flow to some degree, resulting in wasted energy. The fact that superconductors conduct electricity without dissipating energy has long lead to dreams of significantly more efficient power grids. In addition, the way in which rivers of electric currents course through them means superconductors can serve as powerful electromagnets, for applications such as maglev trains, better MRI scanners for medicine, doubling the amount of power generated from wind turbines, and nuclear fusion power plants.

“Today, companies around the world are fabricating kilometer-long, high-temperature superconductor wires,” says Amit Goyal, SUNY Distinguished Professor and SUNY Empire Innovation Professor at the University of Buffalo in New York.

However, many large-scale applications for superconductors may stay fantasies until researchers can find a way to fabricate high-temperature superconducting wires in a more cost-effective manner.

In the new research, scientists have created wires that have set new records for the amount of current they can carry at temperatures ranging from 5 K to 77 K. Moreover, fabrication of the new wires requires processes no more complex or costly than those currently used to make high-temperature superconducting wires.

“The performance we have reported in 0.2-micron-thick wires is similar to wires almost 10 times thicker,” Goyal says.

At 4.2 K, the new wires carried 190 million amps per square centimeter without any externally applied magnetic field. This is some 50 percent better than results reported in 2022 and a full 100 percent better than ones detailed in 2021, Goyal and his colleagues note. At 20 K and under an externally applied magnetic field of 20 tesla—the kind of conditions envisioned for fusion applications—the new wires may carry about 9.3 million amps per square centimeter, roughly 5 times greater than present-day commercial high-temperature superconductor wires, they add.

Another factor key to the success of commercial high-temperature superconductor wires is pinning force—the ability to keep magnetic vortices pinned in place within the superconductors that could otherwise interfere with electron flow. (So in that sense higher pinning force values are better here—more conducive to the range of applications expected for such high-capacity, high-temperature superconductors.) The new wires showed record-setting pinning forces of more than 6.4 trillion newtons at 4.3 K under a 7 tesla magnetic field. This is more than twice as much as results previously reported in 2022.

The new wires are based on rare-earth barium copper oxide (REBCO). The wires use nanometer-sized columns of insulating, non-superconducting barium zirconate at nanometer-scale spacings within the superconductor that can help pin down magnetic vortices, allowing for higher supercurrents.

The researchers made these gains after a few years spent optimizing deposition processes, Goyal says. “We feel that high-temperature superconductor wire performance can still be significantly improved,” he adds. “We have several paths to get to better performance and will continue to explore these routes.”

Based on these results, high-temperature superconductor wire manufacturers “will hopefully further optimize their deposition conditions to improve the performance of their wires,” Goyal says. “Some companies may be able to do this in a short time.”

The hope is that superconductor companies will be able to significantly improve performance without too many changes to present-day manufacturing processes. “If high-temperature superconductor wire manufacturers can even just double the performance of commercial high-temperature superconductor wires while keeping capital equipment costs the same, it could make a transformative impact to the large-scale applications of superconductors,” Goyal says.

The scientists detailed their findings on 7 August in the journal Nature Communications.

This story was updated on 19 August 2024 to correct Amit Goyal’s title and affiliation.

NEW YORK – Moves by major US fast-food chains to temporarily scrub fresh onions off their menus on Oct 24, after the vegetable was named as the likely source of an E. coli outbreak at McDonald’s, laid bare the recurring nightmare for restaurants: Produce is a bigger problem for restaurants to keep free of contamination than beef. Onions are likely the culprit in the McDonald’s E. coli outbreak across the Midwest and some Western states that has sickened 49 people and killed one, the US Department of Agriculture said late on Oct 23. The company pulled the Quarter Pounder off its menu at one-fifth of its 14,000 US restaurants. In past years, beef patties dominated the dockets of food-borne-illness lawyers, before US federal health regulators cracked down on beef contamination after an E. coli outbreak linked to Jack in the Box burgers hospitalised more than 170 people across states and killed four. As a result, beef-related outbreaks became much rarer, experts say.

Denzel Washington has confirmed he will star in Black Panther 3 before his retirement. The 69-year-old actor is the first to talk about the existence of a third film in the blockbuster Marvel franchise — which will follow the 2018 original and 2022 sequel Black Panther: Wakanda Forever — and has also revealed the film will be among a handful of roles he will take on before he bows out of acting after a career spanning four decades. Confirming director Ryan Coogler has written a role just for the Oscar-winner for the third instalment, Denzel told Australia's Today show: "At this point in my career, I'm only interested in working with the best, I don't know how many more films I will make, probably not that many. I want to do things that I haven't done." Sharing the roles he has lined up before he bids farewell to his Hollywood career, he said: "I played Othello at 22, I'm now going to play it at 70. After that, I'm playing Hannibal. After that, I've been talking with Steve McQueen about a film. After that, Ryan Coogler is writing a part for me in the next Black Panther.
