PROBLEM: What is the sentiment of the following document towards the entity Silvio Berlusconi ? Italian Prime Minister Silvio Berlusconi was attacked  injured in the face by a protester and hospitalized shortly after a political meeting in Milan on Sunday evening.
 Berlusconi was signing autographs when a man from the crowd threw at him a statuette representing the Milan Dome  making his nose and mouth deeply bleed  state-run television RAI reported.
 Under shock  the prime minister was then rushed into a car and driven away to a nearby hospital for first aid assistance. Upon reaching the hospital Berlusconi told a member of his staff that he was "feeling well."
 However  the prime minister's conditions are serious according to the doctor in charge of him. He has suffered a severe nose trauma  broken one of his teeth and injured his lower lip.
 The prime minister would spent the night at the hospital and be kept under medical control for 20 days  the doctor explained.
 The man hid among a small group of protesters who were shouting slogans and whistling at the prime minister. Then  unnoticed by the security  he threw the statuette at Berlusconi's face.
 According to people who spoke to Berlusconi  the prime minister said to be "very disappointed and afflicted by the attack  which is the result of all the poison" lately thrown at him.
 "This is the consequence of the political tensions of these days. While we were in the car going to the rally Berlusconi told me to be very worried and said he hoped nothing would happen " Bonaiuti recalled.
 "But unfortunately this time something very serious did occur " he said.
 Italy's political scene has been lately rocked by fierce contrasts between the opposition and the judiciary on one side  and Berlusconi and his center-right government on the other.
 The prime minister has repeatedly accused the "communist left" of conducting a personal fight against him.
 All Berlusconi's allies condemned the assault linking it to the on-going political tensions and hate campaign.

PROBLEM: What is the sentiment of the following document towards the entity Paul Khairy ? The excitement of sports is likely responsible for the observed increases in heart rate  said study author Dr. Paul Khairy  a cardiologist at the Montreal Heart Institute.
But the new study is the first to demonstrate that the ambience of a live game â being surrounded by cheering fans  being closer to the action and experiencing an increased level of engagement â may all contribute to the heightened emotional stress response in fans   Khairy  told Live Science.
In the study  the heart rates of fans who watched a hockey game in person increased by 110 percent  on average  from their resting heart rates. That's comparable to the increase you'd see in someone running  jumping rope or doing any other vigorous form of exercise   Khairy  said.
Fans who watched the same game on TV had a 75 percent increase in their heart rates  on average  which is similar to the heart rates seen with moderate physical activity  such as a casual bike ride   Khairy  noted.
Surprisingly  a person's interest in the sport and engagement as a fan were not linked to changes in heart rate during the game   Khairy  said. However   he  added that  he  suspects there might have been a different result if researchers had developed their own way to measure passion in hockey fans rather than adapting a tool originally designed for soccer spectators.
Although fans watching any sport can experience a similar amount of excitement as was observed in this group of hockey enthusiasts  these results may not apply to other sports   Khairy  said. There are too many elements that differ among sports â such as the pace of the game  a fan's emotional attachment to a team  and even the number of high-intensity moments â that prevent researchers from making similar generalizations   he  said.
A fan's emotional reaction to a game can be intense   Khairy  said  and that could trigger cardiovascular problems.
Fans who experience cardiac symptoms during a game should seek immediate medical attention rather than waiting for a convenient moment  such as in-between periods   Khairy  said. Many arenas and ice rinks have cardiac defibrillators on hand  as well as people trained in using them   he  added.
