WASHINGTON — U.S. health officials have started two new studies to test various blood thinners to try to prevent strokes, heart attacks, blood clots and other complications in COVID-19 patients.Doctors increasingly are finding blood clots throughout the bodies of many people who died from COVID-19 along with signs of damage they do to kidneys, lungs, blood vessels, the heart and other organs.National Heart, Lung and Blood Institute Director Gary Gibbons says that hospitals have been giving seriously ill patients anti-clotting drugs to try to prevent this, but “quite frankly, we didn’t know how best to treat it” in terms of which drugs or doses to use and at what stage of illness.The National Institutes of Health will coordinate a study in hospitalized patients comparing low and regular doses of the blood thinner heparin. The study will involve more than 100 sites around the world participating in a research effort with various governments, drug companies, universities and others to speed coronavirus therapies.A second study in COVID-19 patients not sick enough to need hospitalization will test various strategies against placebo pills: baby aspirin or low or regular doses of the anti-clotting drug apixaban, sold as Eliquis in the United States. The goal there is preventing blood clots or hospitalization.A third study starting later will test blood thinners for people who have recovered and no longer test positive for the coronavirus. Evidence is building that they may remain at higher risk for blood clots. 1538

WASHINGTON — The Supreme Court has upheld a provision of federal law that requires foreign affiliates of U.S.-based health organizations to denounce prostitution as a condition of receiving taxpayer money to fight AIDS around the world. The Supreme Court ruled 5-3 on Monday. Justice Brett Kavanaugh wrote for the court’s conservatives that “plaintiffs’ foreign affiliates are foreign organizations, and foreign organizations operating abroad possess no rights under the U. S. Constitution.” Justice Elena Kagan sat out the case, presumably because she worked on an earlier version of it when she served in the Justice Department before joining the court. 663

VISTA, Calif. (CNS) - A 54-year-old Poway man accused of killing a young woman in Carlsbad 33 years ago pleaded not guilty Tuesday to charges of murder and rape.James Charles Kingery faces 33 years to life in state prison if convicted of all charges stemming from the killing of 26-year-old Julia Hernandez-Santiago, according to the San Diego County District Attorney's Office.The victim's body was found on Oct. 10, 1987 on an ivy-covered embankment in the 2100 block of Alga Road, Carlsbad police spokesman Jodee Reyes said.The San Diego County Medical Examiner's Office determined the cause of death was asphyxiation due to strangulation.While a suspect was not identified at the time of the killing, investigators said technological advances eventually led to Kingery's arrest.In March, San Diego County sheriff's deputies arrested a man on narcotics and weapons violations and took a DNA sample from him, as required by law based on his alleged offenses, Reyes said. Then in May, the sheriff's crime lab notified Carlsbad police that DNA samples from the 1987 murder case were a match for Kingery, who was arrested July 22.A suspected motive for the killing has not been disclosed."When a murder goes unsolved, not only is justice delayed, but families are left in turmoil with no closure," District Attorney Summer Stephan said in a statement. "Working with Carlsbad Police Department detectives, who never gave up, our office is bringing a measure of justice to Ms. Hernandez-Santiago's family and giving hope to other victims in unsolved cases."Kingery is being held on million bail. He's due back in court Sept. 4 for a readiness conference. 1662

WASHINGTON — The number of Americans applying for unemployment benefits rose again last week to 885,000 as a resurgence of coronavirus cases threatens the economy’s recovery from its springtime collapse. The number of applications increased from 862,000 the previous week. It showed that nine months after the viral pandemic paralyzed the economy, many employers are still slashing jobs as the pandemic forces more business restrictions and leads many consumers to stay home. Before the coronavirus erupted in March, weekly jobless claims had typically numbered only about 225,000. The far-higher current pace of claims reflects an employment market under stress and diminished job security for many.The new figures were released as federal lawmakers neared a deal for further COVID-19 stimulus, which could include government-issued checks and extended unemployment benefits. 884
