内容摘要：The eGFR, or estimated glomerular filtration rate, evaluates kidney health based on how quickly a waste compound called creatinine gets filtered from blood. In 1999, an equation used to calculate eGFR was modified to adjust Black people’s results compared to everyone else’s, based on some studies with small numbers of Black patients and a long-ago false theory about differences in creatinine levels. Until recently that meant many lab reports would list two results — one calculated for non-Black patients and another for Black patients that could overestimate kidney function by as much as 16%.

The eGFR, or estimated glomerular filtration rate, evaluates kidney health based on how quickly a waste compound called creatinine gets filtered from blood. In 1999, an equation used to calculate eGFR was modified to adjust Black people’s results compared to everyone else’s, based on some studies with small numbers of Black patients and a long-ago false theory about differences in creatinine levels. Until recently that meant many lab reports would list two results — one calculated for non-Black patients and another for Black patients that could overestimate kidney function by as much as 16%.

Many votes in the first round went to protest candidates. Among voters aged 18–29, over 35% backed Mentzen, and nearly 20% supported a left-wing candidate, Adrian Zandberg, according to exit polls.In addition, an extreme right-wing antisemite, Grzegorz Braun, won more than 6% of the votes overall.

Buras believes right-wing protest candidates are more appealing today than those on the left because they promise to restore a lost past, while the left promises a better future that many see as unattainable.“The world is changing, society is changing very fast, much faster than anytime in the past,” Buras said. “People are worried and they vote for those who say we can go back to the glorious past.”Since the first round, Mentzen — co-leader of the Confederation party — has presented both candidates with an eight-point list of demands: no new taxes; defense of cash payments; expanded gun rights; and opposition to NATO membership for Ukraine, among others.

Nawrocki, who appeared on Mentzen’s show on June 22, signed on to all eight points — including the controversial Ukraine stance — breaking with his Law and Justice party’s longstanding support for Kyiv’s integration with the West.Trzaskowski appeared two days later. He said he could agree with some points, like fiscal restraint, but rejected others. He strongly defended LGBTQ+ rights and reaffirmed that Ukraine should eventually join NATO, once the war ends, calling it key to Poland’s own security.

The YouTube interviews have dominated the political conversation, underscoring how Mentzen, a TikTok-savvy outsider, has upended traditional campaigning.

The exchange between Trzaskowski and Mentzen on Saturday was occasionally tense, especially over LGBTQ+ rights, but remained civil and substantive.“I say this: ... Neither powers nor princes can change the truth and deny that diversity is our strength,” Scully said.

It was a sentiment echoed by Yurong “Luanna” Jiang, a Chinese graduate who studied international development. She described growing up believing that the “world was becoming a small village” and finding a global community at Harvard. But she worries that world view is increasingly under threat.“We’re starting to believe those who think differently, vote differently or pray differently, whether they are across the ocean or sitting right next to us, are not just wrong — we mistakenly see them as evil,” she said. “But it doesn’t have to be this way.”

Dr. Abraham Verghese, a bestselling author and Stanford University expert on infectious diseases, opened his keynote address by saying he felt like a medieval messenger “slipping into a besieged community.” He praised Harvard for “courageously defending the essential values of this university and indeed of this nation,” and told students that more people than they realize have noticed the example they’ve set.“No recent events can diminish what each of you have accomplished here,” Verghese said.
