"By examining big data in entirely new ways, the team uncovered several drug combinations associated with increased risk of a potentially fatal heart arrhythmia. One pair included the popular antibiotic ceftriaxone and the heartburn medication lansoprazole, a former blockbuster drug best known by the brand name Prevacid."

"Millions of Americans take more than one prescription drug, and often times doctors don't know which drugs, when combined, can cause serious illness or death. Sadly, such warnings come only after the damage is done, when enough clear reports of adverse reactions begin to emerge. Now, scientists at Columbia University in New York have harnessed the power of data science to identify two common prescription drugs that, if mixed, can have deadly consequences."

"The research, which used a combination of adverse event data-mining, electronic health record analysis and laboratory experiments, found that patients who received both drugs together were more likely to experience drug-induced long QT syndrome (LQTS), a potentially fatal condition, than those who received either drug alone."

"Investigators at Columbia University discovered that adverse event reports and electronic health records, along with targeted tests, were effective in confirming the challenging-to-predict interactions - pinpointing the peril of one specific combination therapy."

Birth Month Affects Lifetime Disease Risk: A Phenome-Wide Method. Journal of the American Medical Informatics Association June 2015

"By delving into the extensive database of patients seen at Columbia Medical Center over 14 years, beginning in 2000, Tatonetti and his team did a first-of-its kind look at whether birth month has anything to do with disease risk."

"Mary Regina Boland, Nicholas Tatonetti and other researchers at the Columbia University Department of Medicine examined records for an incredible 1.75 million patients born between 1900 and 2000 who had been treated at Columbia University Medical Center. Using statistical analysis, they combed through 1,688 different diseases and found 55 that had a correlation with birth month."

"The Columbia researchers also found that one in 675 occurrences of ADHD (attention deficit hyperactivity disorder) could relate to being born in New York in November, which matches a Swedish study showing the highest rates of ADHD in November babies."

"The results of this study should be interpreted carefully, researchers said. For one, the study only examined data collected from one hospital in New York City; therefore, health data may be skewed due to New York's climate. Furthermore, sick patients tend to be overrepresented in electronic health records, because, well, they are visiting the doctor more often."

"Columbia University scientists compiled the birthdays and medical records of patients from New York City databases and found that people with May birthdays may have the healthiest outcomes, while people born in October might be at the highest risk for certain diseases."

"Using automated software tools to examine queries by six million Internet users taken from Web search logs in 2010, the researchers looked for searches relating to an antidepressant, paroxetine, and a cholesterol lowering drug, pravastatin. They were able to find evidence that the combination of the two drugs caused high blood sugar."

"There's always that part at the end of drug commercials that goes something like: if you develop sausage fingers, webbed feet, or a three-week erection, call your doctor! But as exhaustive as those auctioneer-style lists sound, they barely scratch the surface when it comes to the side effects people are actually experiencing."

"It's a funny thing about clinical trials: they're set up so that all the subjects taking the drug in question are totally healthy in every other respect and on no other medications. It's the only way to see if the drug has an effect, but as soon as people start taking it in the real world, well... let's just say that most patients don't measure up to the pristine condition of clinical subjects."
