Increased UHMWPE Particle-Induced Osteolysis in Fetuin-A-Deficient Mice.

Particle-induced osteolysis is a major cause of aseptic prosthetic loosening. Implant wear particles stimulate tissue macrophages inducing an aseptic inflammatory reaction, which ultimately results in bone loss. Fetuin-A is a key regulator of calcified matrix metabolism and an acute phase protein.

Experiences and attitudes of collegiate athletic trainers regarding alcohol-related unintentional injury in athletes.

Context: Alcohol-related unintentional injury (ARUI) has been an unexamined consequence of alcohol consumption by collegiate athletes. It has a potentially devastating effect on their athletic performances and careers. Awareness of this problem in athletes could have a huge effect on what athletic trainers (ATs) do to recognize, treat, and prevent it in a collegiate athlete population.

Campus involvement, perceived campus connection, and alcohol use in college athletes.

This research study examined the relationship of college athletes' levels of campus involvement and campus connection to their alcohol use. A survey measuring alcohol use, campus involvement and campus connection was administered to 720 athletes at nine institutions. Participants who reported having 5 or more drinks on one occasion in the past two weeks had higher levels of campus connection than those who did not report that level of alcohol consumption; but, conversely these college athletes also reported lower levels of campus involvement.
