Antibiotics are powerful, they fight off infections and save lives. But the U.S. Food and Drug Administration now warns that a common class of antibiotics could cause an aortic aneurysm. And this could lead to fatal bleeding.The class of antibiotics is called fluoroquinolone. There are used to treat a variety of illnesses like pneumonia, urinary tract infections, respiratory infections and the plague. Now fluoroquinolone antibiotics are sold under different drug names, so check your medicines for names like:ciprofloxacin (Cipro)gemifloxacin (Factive)levofloxacin (Levaquin)moxifloxacin (Avelox)norfloxacin (Noroxin)ofloxacin (Floxin)The FDA looked at the latest research, focusing on studies between 2015 and 2018. They found that when patients were prescribed a fluoroquinolone drug, they were twice as likely to have an aortic aneurysm. The aorta is a major blood vessel. Its job is to carry blood from your heart to your body. If you have an aortic aneurysm, this means an abnormal bulge or ballooning has happened in the wall of the aorta. If it grows large enough, it can burst and dangerous bleeding can happen, or even death.People who have an increased risk include the elderly, folks with high blood pressure, anyone with a history of aneurysms or blockages of blood vessels, patients with peripheral atherosclerotic vascular diseases and those with genetic disorders like Marfan syndrome and Ehlers-Danlos syndrome.If you are taking this medication, please don’t stop using it before discussing it first with your doctor because fluoroquinolones may be the only antibiotic treatment to fight what illness you have. But if you get symptoms like sudden, severe and constant pain in the stomach, chest or back, you need to get emergency help immediately. Fluoroquinolones have been used for 30 years and, overall, the risk of an aortic aneurysm is low. So if you’re not in the high-risk category, this antibiotic could still be a good option to fight bacterial infections. 2001

Boeing unveiled an overhaul Wednesday to a software system and the pilot training of its signature 737 MAX plane, marking its most direct attempt to fix an element of the plane's original design that investigators believe led to two recent crashes.At the company's plant in Renton, Washington, where the plane is assembled, Boeing pilots ran through scenarios on a flight simulator that was transmitted live into a conference room where regulators and some 200 pilots from client airlines were gathered, according to Mike Sinnett, Boeing's vice president for product strategy. The guests were able to request test simulations."We're working with customers and regulators around the world to restore faith in our industry and also to reaffirm our commitment to safety and to earning the trust of the flying public," Sinnett said. "The rigor and thoroughness in the design and testing that went into the MAX gives us complete confidence that the changes we're making will address any of these accidents."The gathering came at a 1038

Apple has removed 181 vaping-related apps from its mobile App Store globally, the company said on Friday."Recently, experts ranging from the CDC to the American Heart Association have attributed a variety of lung injuries and fatalities to e-cigarette and vaping products, going so far as to call the spread of these devices a public health crisis and a youth epidemic. We agree, and we've updated our App Store Review Guidelines to reflect that apps encouraging or facilitating the use of these products are not permitted," the company said in a statement.Apple said the apps are a mix of stores, social networks, news and games. They represent 0.00010% of the 1.8 million apps available through the mobile App Store, the company said.The company said it had been moving in this direction for months. In June, Apple prohibited the promotion of vaping products in its app store and had not approved any new vaping-related apps since.The apps now banned from the App Store will continue to work for customers who already have them downloaded on their devices, and they can be transferred to new devices.Apple's move was applauded by groups such as the American Heart Association and the ghd Campaign for Tobacco-Free Kids."By taking e-cigarette related apps off the App Store, Apple will help reduce youth exposure to e-cigarette marketing and discourage youth use of these products. Apple is setting a welcome example of corporate responsibility in protecting our kids," Matthew L. Myers, president of the Campaign for Tobacco-Free Kids, said in a statement.Research published recently in the medical journal JAMA found that in 2019, 27.5% of high school students and 10.5% of middle school students currently use e-cigarettes. Based on that data from the National Youth Tobacco Survey, researchers estimated 4.1 million US high school students and 1.2 million middle school students currently use e-cigarettes, and 970,000 use them daily.Aside from the youth vaping epidemic, there were 2,172 cases of lung injury linked to vaping as of November 13, the US Centers for Disease Control and Prevention said on Thursday. The CDC also reports 42 confirmed deaths in 24 states and the District of Columbia.The CDC says it has yet to identify the official cause or causes of the outbreak, but the investigation has increasingly focused on products containing THC. Last week, the agency reported its first "potential chemical of concern": vitamin E acetate?, an additive sometimes used in THC and other vaping products. 2525
