Dr. Scott Gottlieb, commissioner of the US Food and Drug Administration, announced Tuesday a "blitz" on retailers?for violations related to sales of Juul and other e-cigarettes to minors.Forty warning letters were sent to brick-and-mortar retailers as a first step toward stopping underage use of e-cigarettes, the FDA said. The government agency also said it sent Juul Labs, the maker of an e-cigarette popular among teens, a request to submit documents related to product marketing and research, including information about "youth initiation and use.""We don't yet fully understand why these products are so popular among youth," Gottlieb wrote in the public statement. "But it's imperative that we figure it out, and fast. These documents may help us get there."Juul spokeswoman Victoria Davis said the company "agrees with the FDA that illegal sales of our product to minors are unacceptable. We already have in place programs to prevent and, if necessary, identify and act upon these violations at retail and online marketplaces, and we will announce additional measures in the coming days."Electronic cigarettes (also called e-cigarettes or e-cigs), vapes, vaporizers and hookah pens are among the terms used to describe electronic nicotine delivery systems. These products use an "e-liquid" that may contain nicotine as well as flavorings and other ingredients. The liquid is heated into an aerosol that the user inhales. Some products resemble conventional cigarettes, but others look like pens or other ordinary items. Juul resembles an everyday flash drive, which may explain its popularity among teens.The FDA has conducted 908,280 inspections of tobacco retailers, issued 70,350 warning letters and initiated about 17,000 civil money penalty cases in its efforts to fight the sale of e-cigarettes and other tobacco products to minors, it said Tuesday. For the current "blitz," the agency said, it also contacted one online retailer, which removed listings for Juul products and then voluntarily implemented policies to prevent future listings.More than 2 million middle and high school students described themselves as current users of e-cigarettes in 2016 (the most recent year studied), according to a government report: about 11% of high school students and 4.3% of middle school students. Overall, e-cigarette use by high school students increased 900% from 2011 to 2015, according to a separate 2016 report from the US surgeon general.In a recent Johns Hopkins Bloomberg School of Public Health survey, 81% of minors who currently vape said their primary reason for doing so is "availability of appealing flavors.""Widespread reports of youth use of JUUL products are of great public health concern," Gottlieb said in the announcement. "Youth may not understand the nicotine or other characteristics of JUUL."On March 20, the FDA issued a warning that it would act to end the use of e-cigarettes among minors.Juul Labs' website tells the story of two founders, smokers and product designers who had become "increasingly dissatisfied with the health and social impacts of cigarettes" but could find no viable alternative and so created their own -- with "adult smokers in mind.""We are working with the FDA, lawmakers, parents and community leaders to combat underage use, and we will continue working with all interested parties to keep our product away from youth," Davis said on behalf of the company. 3473

  

During the COVID-19 pandemic, researchers at the Cleveland Clinic have found a significant increase in patients experiencing stress cardiomyopathy, also known as "broken heart syndrome," which has symptoms similar to a heart attack, according to a new study from the clinic.“Especially when it comes to the loss of a job and economic stressors, those are things that the COVID pandemic is affecting in many people,” said Dr. Grant Reed. “So it’s not just the virus itself that’s causing illness in patients.”Heartbreak is a common thread in movies, pop culture, and music but Cleveland Clinic cardiologists are warning patients about the serious effects of a broken heart and the possible connection with the COVID-19 pandemic.“No one really expected to be in this situation and the pandemic has put dramatic, unprecedented stressors on our life,” Reed said. “These are patients that are coming in presenting very similar to how patients come in with a heart attack. They have EKG changes consistent with a heart attack and they have chest discomfort.”Researchers said stress cardiomyopathy happens in response to physical or emotional stress, which causes dysfunction or failure in the heart muscle.“The COVID-19 pandemic has brought about multiple levels of stress in people’s lives across the country and world. People are not only worried about themselves or their families becoming ill, but they are also dealing with economic and emotional issues, societal problems and potential loneliness and isolation,” said Ankur Kalra, M.D., a Cleveland Clinic cardiologist in the Sections of Invasive and Interventional Cardiology and Regional Cardiovascular Medicine, who led the study.Patients with this condition have experienced symptoms similar to a heart attack, such as chest pain, shortness of breath, but usually don’t have acutely blocked coronary arteries.“The stress can have physical effects on our bodies and our hearts, as evidenced by the increasing diagnoses of stress cardiomyopathy we are experiencing,” said Kalra.Patients can also experience irregular heartbeat, fainting, low blood pressure, and cardiogenic shock, which happens when the heart can’t pump enough blood to meet the body’s demand due to stress hormones.Researchers have admitted the causes of stress cardiomyopathy are not fully understood.Between March 1 and April 30, cardiologists looked at 258 patients with heart symptoms coming into Cleveland Clinic and Cleveland Clinic Akron General. Researchers compared them with four control groups and found a “significant increase” in patients diagnosed with cardiomyopathy, reaching 7.8% compared with a pre-pandemic incidence of 1.7%, the release states.All patients diagnosed with stress cardiomyopathy tested negative for COVID-19. Those with the condition since the COVID-19 outbreak had a longer hospital stay compared to those pre-pandemic. Doctors said patients with stress cardiomyopathy patients generally recover in a matter of days or weeks, although the condition can occasionally cause major adverse cardiac and cerebrovascular events.“For those who feel overwhelmed by stress, it’s important to reach out to your healthcare provider. Exercise, meditation, and connecting with family and friends, while maintaining physical distance and safety measures, can also help relieve anxiety," said Grant Reed, director of Cleveland Clinic’s STEMI program and senior author for the study.Reed said a number of factors can cause heart function to deteriorate, which include loneliness, financial stress, or overwhelming feelings of uncertainty brought on by stay-at-home orders.“You have to recognize when you need to seek help and say, ‘Okay I need to take a step back.’ Maybe disconnect from social media and not read so much because that can stress us all out,” Reed said.Researchers noted that additional research is needed in this area, especially if this trend in cases is present in other regions of the country.WEWS' Kaylyn Hlavaty and Emily Hamilton first reported this story. 4026

  

During her Supreme Court confirmation hearing on Wednesday, Judge Amy Coney Barrett declined to give her legal opinion as to whether a President could pardon himself for crimes he may have committed while in office.Barrett's deferral came during a line of questioning by Senate Judiciary Committee member Patrick Leahy, D-Vermont. Leahy first asked Barrett if she believed that "nobody is above the law," including the President. Barrett agreed.Leahy then asked if she believed a President would be able to pardon himself, given that President Donald Trump has said he believes he has the right to do so in the past."Because it would be opining on an open question when I haven't gone through the judicial process to decide it, it's not one in which I can offer a view," Barrett said.Throughout his questioning, Barrett has attempted to avoid sharing her personal or judicial views on hotly-debated political topics, citing past precedent of previous Supreme Court justice nominees.It is true that the question of a President pardoning himself has not been challenged in court. But in 1974, at the height of the Watergate scandal, the Justice Department faced the possibility that President Richard Nixon would do just that. On Aug. 5, assistant attorney general Mary Lawton issued a memorandum opinion that "no one may be a judge in his own case" and that "the President cannot pardon himself."Despite Lawton's opinion, some legal experts believe that a President may still be able to issue their own pardon. In June 2018, President Donald Trump claimed on Twitter that he had the right to do so while railing against Special Counsel Robert Mueller's investigation into his ties to Russia. 1698
