Constantly beeping alarms in hospitals are being linked to patient deaths and other dangers in a new alert from the Joint Commission.

The alarms can lead to "noise fatigue," and doctors and nurses sometimes inadvertently ignore the sounds when there's a real patient emergency, possibly resulting in treatment delays that endanger patients.

The biggest thing in operating rooms these days is a million-dollar, multi-armed robot named da Vinci, used in nearly 400,000 surgeries nationwide last year — triple the number just four years earlier.

But now the high-tech helper is under scrutiny over reports of problems, including several deaths that may be linked with it and the high cost of using the robotic system.

Manchester City delayed the surrender of its Premier League title to Manchester United on Monday, beating the runaway leaders 2-1 in a frenetic derby thanks to substitute Sergio Aguero's stunning late goal.

The Argentina striker slalomed through United's defense and arrowed a finish high into the net in the 78th minute, cutting second-place City's deficit to 12 points with seven rounds remaining.

Brazil playmaker Hernanes put Lazio ahead but later missed a penalty in a 1-1 draw with Roma in the city derby Monday that left both clubs still battling for Europa League spots.

Hernanes also fouled Miralem Pjanic to give away a penalty for Roma in the 56th minute that was converted by 36-year-old captain Francesco Totti.

Cristiano Ronaldo aims to polish off Galatasaray and ease Real Madrid into the Champions League semifinals, holding a commanding 3-0 advantage heading into Tuesday's meeting in Istanbul.

Ronaldo leads Europe's top-tier competition with nine goals in nine outings. And with Galatasaray needing to score early and often, the prolific Portugal forward will likely enjoy ample chances to add to his tally.

A Swedish league match between Djurgarden and Mjallby was abandoned Monday after a Mjallby player was hit by a pear.

Angry fans at Djurgarden's home stadium in Stockholm threw bottles, coins, fruit and other objects onto the pitch as Mjallby's players celebrated a goal in the 37th minute.

Margaret Thatcher barely concealed her distaste for sports while serving as prime minister of Britain. Instead, she tried to use the athletic arena as a political weapon of sorts during the Cold War, and even took on the football establishment as violence at matches damaged the nation's image.

So divisive was Thatcher's 11-year rule of Britain that her death at the age of 87 on Monday produced no tributes from the country's major sporting institutions. The Premier League even told football clubs that they would not have to hold a minute's silence in honor of the late British leader.

U.S. Navy sailors aboard a supply vessel acted within rules of engagement last year when they fired on a small boat approaching at high speed off Dubai, killing one Indian fisherman and wounding three others, according to a Navy investigation made public Monday.

The July 2012 incident has been described by Navy officials as "regrettable," but it also highlighted the heightened security to protect vessels following boat-borne blasts such as the 2000 suicide attack on the USS Cole in Yemen that killed 17 U.S. sailors and the 2004 explosion of a dhow in Persian Gulf that killed three crew members of the USS Firebolt.

Police say former adult film star Jenna Jameson has been arrested after a report that she attacked someone at a California home.

Newport Beach police Lt. Evan Sailor says the alleged victim put Jameson under citizen's arrest until police arrived Saturday night.

There may be nearly four times as many people infected with the tropical disease dengue globally than was previously believed, according to a new study.

The World Health Organization has estimated there are about 50 million to 100 million cases of dengue, also known as "break-bone fever," every year. But new research puts the number at around 390 million — though about two-thirds of those people have only mild illness and don't need medical attention. The study was published online Sunday in the journal Nature.
