Two items relevant to long COVID

One of the tricky issues in studying in long COVID is: how widely do researchers cast their net? Initial reports acknowledged that people who were hospitalized and in intensive care may take a while to get back on their feet. But the number of people who had SARS-CoV-2 infections and were NOT hospitalized, yet experienced lingering symptoms, may be greater. A recent report from the United Kingdom, published in PLOS Medicine, studied more than Read more

All your environmental chemicals belong in the exposome

Emory team wanted to develop a standard low-volume approach that would avoid multiple processing steps, which can lead to loss of material, variable recovery, and the potential for Read more

Signature of success for an HIV vaccine?

Efforts to produce a vaccine against HIV/AIDS have been sustained for more than a decade by a single, modest success: the RV144 clinical trial in Thailand, whose results were reported in 2009. Now Emory, Harvard and Case Western Reserve scientists have identified a gene activity signature that may explain why the vaccine regimen in the RV144 study was protective in some individuals, while other HIV vaccine studies were not successful. The researchers think that this signature, Read more

Three remarkable Emory case reports from #ACC17

The big news from the American College of Cardiology meeting today is about PCSK9 inhibitors, which were known to be effective at lowering LDL cholesterol, and how much they really prevent heart attacks and save lives.

Lab Land went looking off the beaten path for individual stories of Emory cardiologists saving lives and was pleased to find several. We highlight here three remarkable case reports that are being presented at the ACC meeting. We look forward to learning more about these cases.

Refractory electrical storm 

Electrical storm is life threatening and refers to a recurrent arrhythmia. The arrhythmia did not respond to drug treatment, so anesthesiologists were brought in to perform left stellate ganglion block, an injection of medication into a nerve bundle in the neck, allowing diagnosis and further treatment. It turns out the arrhythmia was caused by sarcoidosis, a rare intrusion of immune cells into the heart. [Saturday morning: Michael Lloyd, Boris Spektor]

Hormone-producing tumor + cardiomyopathy 

A 30-year old woman came to doctors with drastically impaired heart function, although she did not have a blockage of her coronary arteries or signs of damage to the heart muscle. Doctors discovered a tumor near her spine that was producing heart-distorting hormones such as epinephrine. She underwent surgery to remove the tumor. [Saturday afternoon: Stamatios Lerakis]

Giving birth unveils birth defects

Ten days after giving birth, a woman came to a hospital with chest pain. Upon cardiac catheterization, a rearrangement of her coronary arteries was discovered. It appears that the congenital defect had gone undetected until the stress of giving birth. Under medical treatment, she is asymptomatic, but she will need future monitoring and possibly a procedure to correct the artery problems. [Sunday morning: Camden Hebson]
