DCIS Treatments Evolve Over 20 Years, But Cancer Death Rates Vary Little

Treatment patterns for ductal carcinoma in situ (DCIS) have shifted since the 1990s, with more U.S. women opting for lumpectomy in combination with radiation rather than single-breast mastectomy, according to a study lead by Duke Cancer Institute researchers.

Cleaning Hospital Rooms With Chemicals, UV Rays Cuts Superbug Transmissions

In a hospital, what you can’t see could hurt you.

Paul Modrich Shares Nobel Prize in Chemistry for Work in DNA Repair

Paul Modrich, Ph.D., the James B. Duke professor of biochemistry in the Duke University School of Medicine, has been awarded one-third of this year’s Nobel Prize in Chemistry for his four decades of work on how mistakes in the DNA code are repaired.

Duke Establishes First Hand Transplant Program in North Carolina

Duke Medicine has launched the first hand transplant program in North Carolina, becoming one of a small number of transplant centers in the country to offer the life-altering procedure.

Meningitis Model Shows Infection’s Sci-Fi-Worthy Creep Into the Brain

Scientists at Duke Medicine are using transparent fish to watch in real time as Cryptococcal meningitis takes over the brain. The resulting images are worthy of a sci-fi movie teaser, but could be valuable in disrupting the real, crippling brain infection that kills more than 600,000 people worldwide each year.

DART Protein Shows Potential as Shock-and-Kill Strategy Against HIV

A unique molecule developed at Duke Medicine, the University of North Carolina at Chapel Hill and MacroGenics, Inc., is able to bind HIV-infected cells to the immune system’s killer T cells. It could become a key part of a shock-and-kill strategy being developed in the hope of one day clearing HIV infection.

Newly Identified Biochemical Pathway Could Be Target For Insulin Control

In the final event leading to the development of Type 2 diabetes, the pancreas loses its ability to secrete insulin and clear glucose from the blood. Preventing this breakdown in insulin secretion is a key goal in the fight to reduce the burden of a disease that afflicts an estimated 29 million people in the United States.

New Mouse Brain Connectome May Illuminate Origins of Mental Illnesses

Scientists at Duke University have released a highly detailed model of connections in the mouse brain that could provide generations of neuroscientists new insights into brain circuits and origins of mental illness, such as depression and schizophrenia. The findings are published in the journal Cerebral Cortex.

New Technology Weeds Out Patients Who Don’t Need Heart Catheterizations

Chest pain is a symptom of coronary artery disease, and patients are often sent to a cardiac catheterization lab either directly or after stress testing for an invasive procedure to detect blockages.

Breast Cancer Risk Score Impacts Use of Chemotherapy

A genetic test that helps predict whether some women’s breast cancer will recur might influence how chemotherapy is used, according to a study from Duke Medicine.
