The field of pharmacogenomics -- using a patient’s genome to predict how well they will respond to medication -- is a hot area of medicine today. But, almost all data used in these predictions comes from people of European decent. Minoli Perera, PharmD, PhD, wants to change that. She is a pioneer in the area of pharmacogenomics in African-Americans and has some new discoveries to share.

It is possible to improve and prolong the life of patients with hormone receptor-positive metastatic breast cancer, according to the results of a new phase III clinical trial. Massimo Cristofanilli, MD, principal investigator of the trial explains the results and the state of breast cancer in America today. 

A common, safe and inexpensive drug for type 2 diabetes, metformin, decreases the risk of heart attacks and strokes triggered by particulate matter air pollution. Scott Budinger, MD, explains the study and other ways the drug could be used to protect people at risk of heart attack and

Chronic pain, such as lower back pain that lasts for months or years, affects 100 million Americans and costs half a trillion dollars a year in healthcare costs.

Physicians are notorious for prescribing antibiotics to people who don't really need them. This can lead to dangerous side effects for patients. Jeffrey Linder, MD, MPH, has developed effective ways to reduce the number of inappropriate prescriptions. He explains how similar interventions can be used to address the prescription opioid crisis.

A new blood test developed at Northwestern has the potential to advance treatments of a variety of disorders and diseases. Phyllis Zee, MD, PhD, explains the test, which can reveal if an individual’s circadian clock is running too fast or too slow and how circadian clocks impact far more than sleep.

More than 50 percent of women who are of childbearing age are overweight or obese, which may put them at risk for complications during pregnancy and child birth and affect their babies’ health, too. Alan Peaceman, MD, shares results of a new clinical trial, aimed to help these women safely reduce their weight gain with diet and exercise interventions.

Some people’s brains are aging at a rate much slower than average. They are called SuperAgers, men and women over the age of 80 with the mental faculties of people decades younger. Emily Rogalski, PhD, has been studying SuperAgers for a decade and reveals some fascinating findings about their brains and lives.

Anticipating, preventing and treating suffering is at the heart of excellent palliative care. Kelly Michelson, MD, MPH, discusses the importance palliative care in pediatric hospitals and how she works with young patients and their families when they're facing a deadly health condition.

John A. Rogers, PhD, has created a fleet of wireless, wearable devices that have the potential to change the way physicians collect data and treat patients, from NICU preemies to stroke patients in recovery.
