‘Genetic doppelgangers:’ Emory research provides insight into two neurological puzzles

An international team led by Emory scientists has gained insight into the pathological mechanisms behind two devastating neurodegenerative diseases. The scientists compared the most common inherited form of amyotrophic lateral sclerosis and frontotemporal dementia (ALS/FTD) with a rarer disease called spinocerebellar ataxia type 36 (SCA 36). Both of the diseases are caused by abnormally expanded and strikingly similar DNA repeats. However, ALS progresses quickly, typically killing patients within a year or two, while the disease Read more

Emory launches study on COVID-19 immune responses

Emory University researchers are taking part in a multi-site study across the United States to track the immune responses of people hospitalized with COVID-19 that will help inform how the disease progresses and potentially identify new ways to treat it.  The study is funded by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health. The study – called Immunophenotyping Assessment in a COVID-19 Cohort (IMPACC) – launched Friday. Read more

Marcus Lab researchers make key cancer discovery

A new discovery by Emory researchers in certain lung cancer patients could help improve patient outcomes before the cancer metastasizes. The researchers in the renowned Marcus Laboratory identified that highly invasive leader cells have a specific cluster of mutations that are also found in non-small cell lung cancer patients. Leader cells play a dominant role in tumor progression, and the researchers discovered that patients with the mutations experienced poorer survival rates. The findings mark the first Read more

Really? I had a heart attack?

A recent Harvard study, published in Circulation, found a surprising level of inconsistency between what medical records say about whether people had a heart attack and what they report themselves in surveys.

About a quarter of Medicare patients who said in a survey that they previously had a heart attack have no record of having any heart-related hospital admission. Conversely, about one-third of patients who, according to Medicare, experienced a heart attack said they hadn’t.

This finding is consistent with an Emory study from cardiologists Neal Dickert and Habib Samady, in which participants in a clinical trial were interviewed just a couple days after the initial procedure. The trial was testing a “post-conditioning” modification of angioplasty+stenting performed during treatment for a heart attack. Just over half (55 percent) of the participants initially remembered being asked to participate when asked. Read more
