Study Finds Covid Can Damage Mitochondria In Heart Tissue

CIDRAP: SARS-CoV-2 Can Damage Mitochondrion In Heart, Other Organs, Study Finds
The COVID-19 International Research Team (COV-IRT) and the Children's Hospital of Philadelphia (CHOP) report that they have identified abnormal mitochondrial function in the heart, kidneys, and liver after SARS-CoV-2 infection, which leads to long-term damage and may help explain long COVID. Mitochondria are the so-called "powerhouses" of cells, and the researchers noted that previous studies have shown that SARS-CoV-2 proteins can bind to mitochondrial proteins in host cells, possibly leading to dysregulation.

AP: COVID-19 Took A Toll On Heart Health And Doctors Are Still Grappling With How To Help
Firefighter and paramedic Mike Camilleri once had no trouble hauling heavy gear up ladders. Now battling long COVID, he gingerly steps onto a treadmill to learn how his heart handles a simple walk. “This is, like, not a tough-guy test so don’t fake it,” warned Beth Hughes, a physical therapist at Washington University in St. Louis. Somehow, a mild case of COVID-19 set off a chain reaction that eventually left Camilleri with dangerous blood pressure spikes, a heartbeat that raced with slight exertion, and episodes of intense chest pain. Doctors were stumped until Camilleri found a Washington University cardiologist who’d treated patients with similar post-COVID heart trouble. (Neergaard, 8/10)

Reuters: With Eris On The Rise, US CDC Sees No Major Shift In COVID Variants
Currently spreading COVID-19 variants such as EG.5, or Eris, do not represent a major shift and updated vaccines in September will offer protection, the director of the U.S. Centers for Disease Control and Prevention said on Wednesday. "Right now, what we're seeing with the changes in the viruses, they're still susceptible to our vaccine, they're still susceptible to our medicines, they're still picked up by the tests," Director Dr. Mandy Cohen said in an interview on former Biden administration adviser Andy Slavitt's "In the Bubble" podcast. "We're seeing small changes that are what I would call subtypes of what we've seen before." (8/9)

AP: An Illicit, Chinese-Owned Lab Fueled Conspiracy Theories. But Officials Say It Posed No Danger
Jesalyn Harper, the only full-time code enforcement officer for the small, agricultural city of Reedley in California’s Central Valley, was responding to a complaint about vehicles parked in the loading dock of a cold-storage warehouse when she noticed a foul smell and saw a garden hose snaking into the old building. A woman in a lab coat answered her knock, and behind her were two others in plastic gloves and blue surgical masks, packing pregnancy tests for shipping. Harper said they spoke broken English and told her they were from China. Walking through the lab, she found dozens of refrigerators and ultralow-temperature freezers hooked to illegal wiring; vials of blood and jars of urine in shelves and plastic containers; and about 1,000 white lab mice being kept in crowded, soiled containers.
