Neurosurgeon Vitor Mendes Pereira has grown accustomed to treating brain aneurysms with only blurry images for guidance.

Equipped with a rough picture of the labyrinthine network of arteries in the brain, he does his best to insert mesh stents or coils of platinum wire—interventions intended to promote clotting and to seal off a bulging blood vessel.

The results are not always perfect. Without a precise window into the arterial architecture at the aneurysm site, Pereira says that he and other neurovascular specialists occasionally misplace these implants, leaving patients at a heightened risk of stroke, clotting, inflammation, and life-threatening ruptures. But a new fiber-optic imaging probe offers hope for improved outcomes.

Pereira et al./Science Translational Medicine

According to Pereira’s early clinical experience, the technology—a tiny snake-like device that winds its way through the intricate maze of brain arteries and, using spirals of light, captures high-resolution images from the inside-out—provides an unprecedented level of structural detail that enhances the ability of clinicians to troubleshoot implant placement and better manage disease complications.

“We can see a lot more information that was not accessible before,” says Pereira, director of endovascular research and innovation at St. Michael’s Hospital in Toronto. “This is, for us, an incredible step forward.”

And not just for brain aneurysms. In a report published today in Science Translational Medicine, Pereira and his colleagues describe their first-in-human experience using the platform to guide treatment for 32 people with strokes, artery hardening, and various other conditions arising from aberrant blood vessels in the brain.

Whereas before, with technologies such as CT scans, MRIs, ultrasounds, and x-rays, clinicians had a satellite-like view of the brain’s vascular network, now they have a Google Street View-like perspective, complete with in-depth views of artery walls, plaques, immune cell aggregates, implanted device positions, and more.

“The amount of detail you could get you would never ever see with any other imaging modality,” says Adnan Siddiqui, a neurosurgeon at the University at Buffalo, who was not involved in the research. “This technology holds promise to be able to really transform the way we evaluate success or failure of our procedures, as well as to diagnose complications before they occur.”

A Decade of Innovation

The new imaging platform is the brainchild of Giovanni Ughi, a biomedical engineer at the University of Massachusetts’ Chan Medical School in Worcester. About a decade ago, he set out to adapt a technique called optical coherence tomography (OCT) for imaging inside the brain’s arteries.

OCT relies on the backscattering of near-infrared light to create cross-sectional images with micrometer-scale spatial resolution. Although OCT had long been used in clinical settings to generate pictures from the back of the eye and from inside the arteries that supply blood to the heart, the technology had proven difficult to adapt for brain applications owing to several technical challenges.

One major challenge is that the fiber-optic probes used in the technology are typically quite stiff, making them too rigid to twist and bend through the convoluted passageways of the brain’s vasculature. Additionally, the torque cables—traditionally used to rotate the OCT lens to image surrounding vessels and devices in three dimensions as the probe retracts—were too large to fit inside the catheters that are telescopically advanced into the brain’s arteries to address blockages or other vascular issues.

“We had to invent a new technology,” Ughi explains. “Our probe had to be very, very flexible, but also very, very small to be compatible with the clinical workflow.”

To achieve these design criteria, Ughi and his colleagues altered the properties of the glass at the heart of their fiber-optic cables, devised a new system of rotational control that does away with torque cables, miniaturized the imaging lens, and made a number of other engineering innovations.

The end result: a slender probe, about the size of a fine wire, that spins 250 times per second, snapping images as it glides back through the blood vessel. Researchers flush out blood cells with a tablespoon of liquid, then manually or automatically retract the probe, revealing a section of the artery about the length of a lip balm tube.

Clinical Confirmation

After initial testing in rabbits, dogs, pigs, and human cadavers, Ughi’s team sent the device to two clinical groups: Pereira’s in Toronto and Pedro Lylyk’s at the Sagrada Familia Clinic in Buenos Aires, Argentina. Across the two groups, neurosurgeons treated the 32 participants in the latest study, snaking the imaging probe through the patients’ groins or wrists and into their brains.

The procedure was safe and well-tolerated across different anatomies, underlying disease conditions, and the complexity of prior interventions. Moreover, the information provided frequently led to actionable insights—in one case, prompting clinicians to prescribe anti-platelet drugs when hidden clots were discovered; in another, aiding in the proper placement of stents that were not flush against the arterial wall.

“We were successful in every single case,” Ughi says. “So, this was a huge confirmation that the technology is ready to move forward.”

A startup called Spryte Medical aims to do just that. According to founder and CEO David Kolstad, the company is in discussions with regulatory authorities in Europe, Japan, and the United States to determine the steps necessary to bring the imaging probe to market.

At the same time, Spryte—with Ughi as senior director of advanced development and software engineering—is working on machine learning software to automate the image analysis process, thus simplifying diagnostics and treatment planning for clinicians.

Bolstered by the latest data, cerebrovascular specialists like Siddiqui now say they are chomping at the bit to get their hands on the imaging probe once it clears regulatory approval.

“I’m really impressed,” Siddiqui says. “This is a tool that many of us who do these procedures wish they had.”

The FDA has proposed removing oral phenylephrine from its guidelines for over-the-counter drugs due to inefficacy as a decongestant. Use of this ingredient in cold and allergy medicines grew after a federal law required that pseudoephedrine-containing products be kept behind pharmacy counters.

CANBERRA — China is putting ever-greater pressure on the Philippines to cede its sovereign rights in the South China Sea, Secretary of National Defence Gilberto Teodoro said on Nov 12 after a meeting with his Australian counterpart in Canberra. "What we see is an increasing demand by Beijing for us to concede our sovereign rights in the area," he said, adding that the Philippines was a "victim of Chinese aggression". China and the Philippines have sparred repeatedly this year over disputed areas of the South China Sea, including the Scarborough Shoal, one of Asia's most contested features. Teodoro's meeting with his Australian counterpart Richard Marles, their fifth since August 2023, reflects growing security ties between the countries, both of whom have expressed concern about Chinese activity in areas of the South China Sea claimed by the Philippines and other Southeast Asian nations. The two nations signed a strategic partnership in September 2023 and held their first joint sea and air patrols in the South China Sea several months later. The Philippines also joined war games in Australia this year for the first time.

The resignation drama has helped distract attention from the DMK party's woes in advance of next years Parliamentary elections.

Only a small handful of people in the world have sat at the negotiating table with the North Koreans and extensively interacted with them. Yet, this knowledge is fragmented and has not been collected or analyzed in a systematic manner. This report captures the findings from in-depth, one-on-one interviews with former senior negotiators from the United States and South Korea, who gained unique knowledge about North Korean negotiating behavior by dealing directly with their high-level North Korean counterparts. 

These negotiators collectively represent a body of negotiation experience and expertise starting from the early 1990s to late 2019, when North Korea ceased all negotiations with the United States. During that time, the conditions for productive negotiation changed dramatically – indeed, the conditions for the 1994 U.S.-North Korea Agreed Framework negotiations were much more favorable than during the Six-Party Talks of the mid-2000s or the Season of Summits during 2018-2019. For the “Negotiating with North Korea: Key Lessons Learned from Negotiators’ Genesis Period” project, a spotlight was placed on former senior negotiators’ early-stage experience preparing for and engaging in negotiations with the North Koreans. In doing so, tacit knowledge was captured to serve as a resource for future negotiators to inform and accelerate their own genesis period.
