Scientists have long known that there is a link between schizophrenia and rheumatoid arthritis. People who suffer from schizophrenia tend not to develop rheumatoid arthritis, and people with rheumatoid arthritis are at low risk for schizophrenia.

Though this relationship has been clear for more than 50 years, nobody really knew why the link existed, according to University of Pittsburgh professor of psychiatry and human genetics Vishwajit Nimgaonkar.

“We thought that there might be genetic factors that might explain this phenomenon,” he said.

Bill Would Lower Hurdles To Collect Suspects’ DNA

Apr 14, 2015

The state Senate is advancing a plan to expand law enforcement’s ability to collect people’s DNA once they’re arrested for certain crimes, but before they’re convicted.  

The measure would let police and prosecutors collect your DNA if you’re arrested for criminal homicide, sex crimes, any felonies, and certain lesser crimes like criminal trespassing and assault.

A plan to expand the state’s DNA collection is under consideration by a state House committee.

The proposal would allow law enforcement to take DNA samples from people arrested for felonies and certain misdemeanor crimes before they are convicted.

Right now, state law allows only for such collection after conviction.

Supporters say the move would help close cases and exonerate innocent individuals.

But the state’s public DNA labs are already swamped, and Pennsylvania State Police Lt. Col. Scott Snyder is urging lawmakers to proceed with caution.
