Potential new treatment approach to fatal COVID-19

Researchers from the University of Colorado Anschutz Medical Campus and Pathways Bioscience in the United States have found that activating a transcription factor involved in oxidative stress regulation, antiviral activity, and inflammation may serve as a new treatment approach to coronavirus disease 2019 (COVID-19).

Equating COVID-19 with high altitude pulmonary edema can have dangerous implications

Early reports of COVID-19 symptoms and the compelling need to quickly identify treatment options and curb the growing number of critically ill patients have led to erroneous and potentially dangerous comparisons between COVID-19 and other respiratory diseases like high altitude pulmonary edema, or HAPE.

Advancing a protein drug in lettuce leaves to treat pulmonary arterial hypertension

In pulmonary arterial hypertension, high blood pressure in the lungs' arteries causes the heart to work extra hard to pump blood to the lungs and around the rest of the body.

Frequent drinking strongest risk factor for atrial fibrillation

A new study published on October 17, 2019, in the journal EP Europace, shows that people who drink alcohol almost every day, even in small amounts, are more at risk to develop an irregular heart rhythm called atrial fibrillation (AF), which is linked to a five-fold higher risk of stroke.

Study provides new insights on exercise limitations in patients with ventricular assist devices

Why don't patients with ventricular assist devices get better improvement in exercise tolerance? Increases in key internal heart pressures appear to be the answer, reports a study in the ASAIO Journal, official journal of ASAIO. The journal is published in the Lippincott portfolio by Wolters Kluwer.

Ultrafast 3D printing technique for artificial tissues

Scientists have come up with a very rapid 3D printing technique for producing the most complex tissue forms in hydrogels which are loaded with stem cells, and then generating the growth of blood vessels in the resulting tissue mass.

New study questions the presumptions about LVADs and mitral regurgitation

Left ventricular assist devices, or LVADs, have been shown to help leaky mitral valves that create significant regurgitation, but a new study questions the presumption that all's well with the mitral valve after a patient receives a LVAD.

Vortex flow closely linked to pressure differences in ventricles of the heart

Japanese scientists at Tokyo University of Agriculture and Technology, Teikyo University of Science, and Juntendo University have found -- in animal studies -- a close relationship between vortex flow and pressure differences in the ventricles, or lower chambers, of the heart.

Patients receiving drug therapy before LVAD implantation have high risk of right-sided heart failure

Patients with left-sided heart failure who get implanted devices to improve the pumping of their hearts may be more likely to develop heart failure on the opposite side of their hearts if they are pre-treated with off-label selective vasodilator drugs, according to new research published in Circulation: Heart Failure, an American Heart Association journal.

First-of-its-kind trial evaluates use of ultrasonic sealing for common thoracic surgical procedure

According to a new study, an ultrasonic vessel-sealing device can improve patient outcomes by reducing the incidence of thoracotomy conversion for VATS/robotic anatomical lung resection.

Less-invasive surgery for lung cancer reduces risk of post-operative bleeding, complications

In a large international clinical study presented at the 99th Annual Meeting of the American Association for Thoracic Surgery, Dr. Moishe Liberman, a thoracic surgeon and researcher at the University of Montreal Hospital Research Center, and his team showed that thoracoscopic lobectomy—video-assisted thoracoscopic surgery—combined with pulmonary artery sealing using an ultrasonic energy device reduced the risk of post-operative bleeding, complications and pain.

CardioMEMS heart failure sensor reliably safe, effectively reduces hospitalizations

In the year following placement of a CardioMEMS heart failure sensor—designed to wirelessly measure and monitor pulmonary artery pressures that can signal worsening heart failure—patients experienced a 58 percent reduction in hospitalization for heart failure, according to research presented at the American College of Cardiology's 68th Annual Scientific Session. Reductions in hospitalizations were seen in both men and women, across all ejection fraction ranges and regardless of race.

Team-based approach is key to successful care of pregnant women with heart failure

Any time a pregnant woman presents in heart failure there are risks to both mother and baby. What does it take to protect the mother and her growing baby for the best possible outcome?

AACN outlines evidence-based protocols and clinical strategies to manage alarms

Clinical alarms are designed to alert clinicians to changes in their patients' conditions, but their sheer numbers and resulting noise instead pose a significant threat to patient safety, according to the American Association of Critical-Care Nurses.

PFKFB3 enzyme appears to play a key role in pulmonary hypertension

A new and early target for treating pulmonary hypertension appears to be an enzyme that's normally key to energy production but destructive in the face of this high blood pressure inside your lungs.

Alfred Blalock’s medical breakthroughs have been saving many lives

The year was 1925, and Alfred Blalock was already a failure at age 26. The born-and-raised Georgian earned a bachelor's degree from the University of Georgia in 1918, then a medical doctorate from Johns Hopkins University four years later. But he didn't get the surgical residency he coveted at Hopkins; he ended up interning in urology instead.
