Former NFL player Jonathon Martin has been taken into custody by Los Angeles police after appearing to post a threatening Instagram story that caused a school to go into lockdown."The individual we believe responsible for the social media post in question has been detained and our investigation is ongoing," the Los Angeles Police Department said in a statement to ESPN.On Friday, an Instagram account appearing to belong to Martin posted a story that included a photo of a long gun and ammunition. The photo included the caption "When you're a bully victim & a coward, your options are suicide, or revenge." The photo also included the hashtag #HarvardWestlake, an apparent reference to a Los Angeles high school and Martin's alma mater. Here is the image from Martin's Instagram Story that prompted the closure pic.twitter.com/dJ9tYww8SL— Matt Stone (@MattStoneABC) February 23, 2018 908

Few masks, no social distancing, hugs, and handshakes were likely a jarring sight for public health experts and Americans cautiously going about life amid the coronavirus pandemic.With hundreds of our nation’s leaders sitting shoulder to shoulder last Saturday in the White House Rose Garden, President Donald Trump picked Judge Amy Coney Barrett to fill the open seat on the Supreme Court following the death of Justice Ruth Bader Ginsburg.In the six days that have followed, at least 10 known coronavirus cases have emerged from that event, including President Donald Trump, first lady Melania Trump, Sens. Thom Tillis, and Mike Lee, Notre Dame John I. Jenkins, Pastor Greg Laurie, Gov. Chris Christie, White House press secretary Kayleigh McEnany and former White House adviser Kellyanne Conway. The White House Correspondents Association (WHCA) also said an unnamed reporter who attended Saturday's announcement also tested positive for the virus. That person became symptomatic on Wednesday and tested positive on Friday. The WHCA has confirmed that two other journalists who cover the White House have tested positive for the virus in recent days, though it's unclear if those unnamed reporters were present for Barrett's nomination. In addition, others who have been in contact with Trump, White House senior aide Hope Hicks, and RNC Chair Ronna McDaniel, have tested positive for the virus. The CDC says that the incubation period for the coronavirus is up to 14 days following infection, meaning it’s possible more attendees could develop symptoms in the coming days.Given the incubation period, the CDC urges those who have been in close contact with positive coronavirus cases to quarantine for 14 days. With a number of prominent members of government now infected with the virus, it’s unclear how many US senators, senior White House aides, and others in the upper echelons of the US government will follow these guidelines after snubbing social distancing guidelines.For those who have been infected, they now are urged to isolate for at least 10 days to prevent the spread of the virus. In severe cases, isolation could be required for up to 20 days, the CDC says. 2187

For the sixth time in the Atlantic hurricane season, people in Louisiana are once more fleeing the state’s barrier islands and sailing boats to safe harbor while emergency officials ramp up command centers and consider ordering evacuations.The storm being watched Wednesday was Hurricane Delta, the 25th named storm of the Atlantic’s unprecedented hurricane season. Forecasts placed most of Louisiana within Delta’s path, with the latest National Hurricane Center estimating landfall in the state on Friday.The center’s forecasters warned of winds that could gust well above 100 mph (160 kph) and up to 11 feet (3.4 meters) of ocean water potentially rushing onshore when the storm’s center hits land.“This season has been relentless,” Louisiana Gov. John Bel Edwards said, dusting off his now common refrain of 2020 - “Prepare for the worst. Pray for the best.”A hurricane warning has been issued for a stretch of the northern U.S. Gulf Coast. The National Hurricane Center in Miami said Delta is expected to become a major hurricane again, like it was days earlier before crossing part of Mexico’s Yucatan Peninsula. But some weakening is forecast once Delta approaches the northern Gulf Coast on Friday.So far, Louisiana has seen both major strikes and near misses. The southwest area of the state around Lake Charles, which forecasts show is on Delta’s current trajectory, is still recovering from an Aug. 27 landfall by Category 4 Hurricane Laura.Nearly six weeks later, some 5,600 people remain in New Orleans hotels because their homes are too damaged to occupy. Trees, roofs and other debris left in Laura’s wake still sit by roadsides in the Lake Charles area waiting for pickup even as forecasters warned that Delta could be a larger than average storm.New Orleans spent a few days last month bracing for Hurricane Sally before it skirted to the east, making landfall in Alabama on Sept. 16.Delta is predicted to strengthen back into a Category 3 storm after hitting the Mexican Yucatan Peninsula on Wednesday, then weaken slightly as it approaches Louisiana. The National Hurricane Center forecast anticipated the storm will come ashore in a sparsely populated area between Cameron and Vermilion Bay.Edwards said President Donald Trump has agreed to sign a federal emergency declaration in advance for the state. The Democratic governor said he doesn’t expect widespread mandatory evacuations.But Edwards said Wednesday that Delta is moving fast, so hurricane force winds could reach well inland, and expected heavy rains could cause flooding.Plywood, batteries and rope already were flying off the shelves at the Tiger Island hardware store in Morgan City, Louisiana, which would be close to the center of the storm’s path.“The other ones didn’t bother me, but this one seems like we’re the target,” customer Terry Guarisco said as a store employee helped him load his truck with plywood needed to board up his home.In Sulphur, across the Calcasieu River from Lake Charles, Ben Reynolds was deciding whether to leave or stay. He had to use a generator for power for a week after Hurricane Laura.“It’s depressing,” Reynolds said. “It’s scary as hell.”By sundown Wednesday, Acy Cooper planned to have his three shrimp boats locked down and tucked into a Louisiana bayou for the third time this season.“We’re not making any money,” Cooper said. “Every time one comes we end up losing a week or two.”Lynn Nguyen, who works at the TLC Seafood Market in Abbeville, said each storm threat forces fisherman to spend days pulling hundreds of crab traps from the water or risk losing them.“It’s been a rough year. The minute you get your traps out and get fishing, its time to pull them out again because something is brewing out there,” Nguyen said.Elsewhere in Abbeville, Wednesday brought another round of boarding up and planning, said Vermilion Chamber of Commerce Executive Director Lynn Guillory.“I think that the stress is not just the stress of the storm this year, it’s everything – one thing after another,” Guillory said. “Somebody just told me, ‘You know, we’ve really had enough.’”On Grand Isle, the Starfish restaurant planned to stay open until it ran out of food Wednesday. Restaurant employee Nicole Fantiny then planned to join the rush of people leaving the barrier island, where the COVID-19 pandemic already devastated the tourism industry.“The epidemic, the coronavirus, put a lot of people out of work. Now, having to leave once a month for these storms — it’s been taking a lot,” said Fantiny. She tried to quit smoking two weeks ago but gave in and bought a pack of cigarettes Tuesday as Delta strengthened.While New Orleans has been mostly spared by the weather and found itself outside Delta’s cone Wednesday, constant vigilance and months as a COVID-19 hot spot have strained a vulnerable city still scarred by memories of 2005′s Hurricane Katrina. Delta’s shifting forecast track likely meant no need for a major evacuation, but the city’s emergency officials were on alert.“We’ve had five near misses. We need to watch this one very, very closely,” New Orleans Emergency Director Collin Arnold said.Along with getting hit by Hurricane Laura and escaping Hurricane Sally, Louisiana saw heavy flooding June 7 from Tropical Storm Cristobal. Tropical Storm Beta prompted tropical storm warnings in mid-September as it slowly crawled up the northeast Texas coast.Tropical Storm Marco looked like it might deliver the first half of a hurricane double-blow with Laura, but nearly dissipated before hitting the state near the mouth of the Mississippi River on Aug. 24.“I don’t really remember all the names,” Keith Dunn said as he loaded up his crab traps as a storm threatened for a fourth time this season in Theriot, a tiny bayou town just feet above sea level.And there are nearly eight weeks of hurricane season left, although forecasters at the National Weather Service office in New Orleans noted in a discussion Tuesday of this week’s forecast that outside of Delta, the skies above the Gulf of Mexico look calm.“Not seeing any signs of any additional tropical weather in the extended which is OK with us because we are SO DONE with Hurricane Season 2020,” they wrote.___Santana reported from New Orleans. Gerald Herbert in Theriot, Louisiana; Kevin McGill in New Orleans; Melinda Deslatte in Baton Rouge, Louisiana; Leah Willingham in Jackson, Mississippi; and Jeffrey Collins in Columbia, South Carolina, contributed to this report. 6475

  

For the first time since 2003, the American Heart Association is updating the comprehensive guidelines for blood pressure and hypertension.According to a release from the AHA, patients with a blood pressure reading of 130/80 should now be considered to have hypertension, or abnormally high blood pressure. Previously, a blood pressure level of 140/90 was the baseline for being diagnosed with hypertension.The new guidelines from the AHA mean that nearly half of all American adults — 46 percent — suffer from hypertension. By the AHA’s old standards, 32 percent of American adults suffered from high blood pressure. “We want to be straight with people – if you already have a doubling of risk, you need to know about it,” said Dr. Paul K. Whelton, the lead author of the AHA’s new guidelines. “It doesn’t mean you need medication, but it’s a yellow light that you need to be lowering your blood pressure, mainly with non-drug approaches.”Despite an increase in the amount of Americans with high blood pressure, the AHA hopes their new guidelines mean there will be only a small increase in the amount of patients requiring medication. The Association now generally recommends that patients with Stage 1 hypertension only be prescribed medication in the event of a heart attack or stroke, and they’re also recommending that pharmaceutical companies combine multiple blood pressure drugs. The AHA also hopes the new guidelines encourage patients to monitor their blood pressure at home, away from a stressful setting like a doctor’s office that can skew a single blood pressure test.According to the AHA, the new guidelines were developed by 21 science and health experts who reviewed more than 900 published studies.The new AHA guidelines for diagnosing hypertension are listed below. 1803
