Other speakers included a couple, Ukrainian physician Dana Rumak and husband Rolin Kostya, who called in from Ivano-Frankivsk, Ukraine. They detailed shortages in medical supplies in and around Kyiv, including a recent report that Russian troops had looted hospitals on their retreat from towns outside the city. They also noted that a nearby factory has recently started production of medical supplies. The couple said they had lived in Bucha — the city where the bodies of hundreds of civilians have been found in the streets after the recent retreat by Russian soldiers — and that one of their biggest uncertainties is how much of Ukraine will be destroyed before the fighting ends.

Gennadiy Fuzaylov, an assistant professor of anesthesia at HMS and MGH, said that he and colleagues, including those at other institutions like Shriners Hospitals, have collected and shipped five containers of medical supplies since the war began to Dnipro, one of Ukraine’s largest cities, southeast of Kyiv. They also sent 16 water filtration units after Dnipro’s water treatment infrastructure was damaged

Fuzaylov has run a program to improve burn care in Ukraine since 2005, when the group brought to the U.S. a 5-year-old girl burned over 85 percent of her body. Fuzaylov said the girl survived and is now 23. He continued to help after that, and in 2011 he and colleagues created a nonprofit called Doctors Collaborating to Help Children, which brings youngsters needing treatment they can’t get in Ukraine to the U.S. for care.

Polina Teslyar, an instructor in psychiatry at HMS and the Brigham, arrived in the U.S. from Ukraine when she was 7, and has family living in Lviv, a major city in western Ukraine near the Polish border.

“This is a very personal and scary time,” Teslyar said. “I’m a descendant of survivors of the Holocaust, so there is a lot of re-traumatization going on. What we’re seeing looks a lot like images from the ’40s.”

Lviv, which has a population a little bigger than Boston’s, is hosting another 300,000 people displaced by the war. Teslyar has relatives who’ve pitched in on the effort, including an aunt who was a yoga instructor and is now managing logistics around Lviv and a 20-year-old cousin who was a college student but is now an army medic.

They’ve been in daily contact, Teslyar said, and the family reaches out through its Boston-area network to procure and send whatever is in short supply, from tourniquets to bulletproof ambulances.

“It started with, ‘We need tourniquets and IV poles and IV bags and insulin,’” Teslyar said, “And then the asks got a little bit bigger, like heat-signature-reading drones so medics can look for survivors in bombed-out areas without being fired on themselves — that was not so hard to get — and then it was things like bulletproof ambulances, which are harder, and more recently they’ve been asking for things like portable ventilators.”
