NIH researchers discover a new tissue biomarker for aggressive breast cancer risk and poorer survival

NIH/Office of the Director
Peer-Reviewed Publication

Researchers at the National Institutes of Health (NIH) have identified a series of changes in the architecture and cell composition of connective tissues of the breast, known as stromal tissue, that is associated with an increased risk of developing aggressive breast cancer among women with benign breast disease, and poorer rates of survival among women with invasive breast cancer. This process, which they call stromal disruption, could potentially be used as a biomarker to identify women with benign breast disease who are at high risk of developing aggressive breast cancers, as well as those with breast cancer who may be at increased risk of recurrence or death.

Cannabis use among older adults

JAMA Network
Peer-Reviewed Publication

About The Study: In this cross-sectional study of cannabis use in veterans ages 65 to 84, use was common, and more than one-third who used in the past 30 days had any cannabis use disorder. The prevalence of past 30-day cannabis use was close to tobacco use prevalence, and risk factors for cannabis use were similar to those observed in other populations. Frequent and inhaled cannabis use was associated with higher odds of any cannabis use disorder. Routine health screening for cannabis use in Veterans Health Administration clinical settings is necessary to identify older adults with cannabis use.

New insights into the energy balance of brain neurons

Universität Leipzig
Peer-Reviewed Publication

A research team at the Carl Ludwig Institute for Physiology at Leipzig University has, for the first time, demonstrated how the energy levels of individual neurons in the brain change during so-called spreading depolarizations – waves of activity that occur in various brain disorders. The findings provide important foundations for understanding energy metabolism in cases of acute cerebral ischaemia, such as that which occurs during a stroke. The study has just been published in the renowned journal PNAS.

IU, Regenstrief researchers develop an app to enable the efficient integration of patient medical information into dental practices

Regenstrief Institute
Business Announcement

Researchers from Indiana University School of Dentistry have developed an app, in collaboration with the technical staff at the Regenstrief Institute, that connects dentists and medical providers to health information exchanges to access a patient’s medical history in a timely manner. The researchers received a National Institutes of Health grant to develop the app further and have partnered with the IU Innovation and Commercialization Office to disclose the technology and are currently exploring the best way to pilot the app in dental practices. it is critical that dentists have up-to-date medical and medication histories of their patients to reduce risk during procedures and ensure the success of the treatment.

People with lupus who have certain antibodies are more likely to experience blood clots, researchers find

Johns Hopkins Medicine
Peer-Reviewed Publication

Some patients with lupus who possess specific antibodies are at a higher risk of thrombotic events such as a blood clot, stroke or heart attack, a new study led by Johns Hopkins Medicine researchers shows. The finding might help clinicians determine which patients may need early treatment and clinical monitoring for thrombotic events.
