College football player Ryan Arnold dreams of playing in the NFL. While chasing his goal, he’s trying to avoid CTE, a degenerative brain disease caused by repeated hits to the head. “When it comes to concussions, I’ve taken some shots,” the linebacker said. “Your body gets hot. Everything pretty much shuts down. Your brain is rattled.” Concussion-related injuries are getting more attention lately. The CDC estimates about 3.8 million sport-related concussions happen each year, with almost half going unreported. “When you have a concussion, there’s many levels to the problem,” said Tony Megna, DACM, MSOM.Megna played football at the University of Wisconsin, but he had his college career derailed by concussions. He is now using traditional Chinese medicine in an attempt to help manage concussion-related injuries of other athletes like Arnold. “We can use acupuncture and Chinese medicine to help facilitate the restoration of the brain, not just to mask some of these pains,” Megna said. But does this kind of old-school, eastern medicine really work?For that answer, we went to UCHealth and spoke with a modern western doctor.“We have an extensive toolbox that we use for headache, but we need more tools,” said Dr. Lauren Grossman, MD, MS.Grossman is the medical director of UCHealth’s integrative medicine center and says traditional Chinese medicine is another way to combat concussion problems. “It’s not like writing a prescription for a pill that either works or doesn’t in one dose,” she said. “In traditional Chinese medicine, we usually recommend the patient have four to six treatments before they decide whether it’s been successful or not.” Back at Megna’s Integrated Heights Wellness and Healing Center, he is practicing acupuncture on Arnold. These athletes swear by the treatment, saying it’s also a lot better than the alternatives. “Is it the answer to everything?” Arnold asked about traditional Chinese medicine. “You don’t know until you try it. But I’d rather try something that’s more beneficial to you than popping pills.” 2068

Climate change is putting shellfish at risk as increases in carbon emissions and agricultural runoff are altering ocean ecosystems.Now oyster farmers are adapting before going extinct.“It’s not that they grow more slowly, it’s that they’re less likely to grow at all,” said Todd Van Herpe of Humboldt County Oyster Co.Van Herpe has been farming northern California’s Humboldt Bay for years. Now his livelihood is at risk after scientists say a change in ocean acidification is making it more difficult for oysters to form their shells and ultimately survive.“They’re like anything else; there’s strong one and a weaker one,” Van Herpe said of young oysters. To help protect his product, Van Herpe is getting seed grown in hatcheries. And in this multimillion-dollar industry, any increase in cost is ultimately passed on to you. “We’re going to have to charge our customers more,” Van Herpe said. At Humboldt Bay Provisions, workers are opening up about the change in the industry. “I’ve noticed it’s getting harder and harder to find the freshest oysters,” said one employee.Now this North Coast oyster restaurant is working with more oyster farmers to get this area’s most iconic seafood.“It’s really a source of pride for the people of Eureka and the people of Humboldt County that we have this right in our backyard,” the worker said. Back on the bay, ocean experts are tracking the change in weather conditions. Dr. Joe Tyburczy of California Sea Grant Extension says oysters are suffering because of an increase in carbon emissions and agricultural runoff, which could mean an end to this industry. “If we’re thinking about mass extinctions and radical changes in marine ecosystems this could drive fisheries collapses,” he said.To help keep more oysters alive oyster alive, oyster farmers like Hog Island Oyster Company is now farming oysters in controlled environments.“We’re doing a lot of research here with eel grass and how eel grass can help with manage the acidity of the water through photosynthesis and respiration and taking some of that carbon dioxide out of the air,” Hog Island Oyster Company scientist Juan Avellaneda, PhD said.Making genetic gains could help this seafood and this industry survive. 2232
