University of Miami Miller School of Medicine Leads Groundbreaking Trial for COVID -19 Treatment

University of Miami Miller School of Medicine researchers led a unique and groundbreaking randomized controlled trial showing umbilical cord derived mesenchymal stem cell infusions safely reduce risk of death and quicken time to recovery for the severest COVID-19 patients, according to results published in STEM CELLS Translational Medicine in January 2021.

Lung Ultrasounds Could Help Determine COVID-19 Outcome

Researchers have developed a method using ultrasound imaging to score a patient’s lung health, which may help predict if a patient with COVID-19 will worsen. Using 14 points in the lungs, they looked for abnormalities and assigned each spot a score out of 3 based on its severity. Adding up all the points, the researchers found the total lung ultrasound score was higher for those who had a worsening outcome of COVID-19. Umberto Sabatini’s presentation will be a part of the 179th ASA Meeting of the Acoustical Society of America.

Healthy Lung Month: Know these pulmonary fibrosis risk factors

October is Healthy Lung Month, an apt time to educate the public about the importance of protecting our lungs against mold, airborne pollutants and smoking – which put hundreds of thousands of Americans at higher risk for pulmonary fibrosis (PF).

Ultrasound Technique Offers More Precise, Quantified Assessments of Lung Health

Researchers have developed a technique that uses ultrasound to provide non-invasive assessments of pulmonary fibrosis and pulmonary edema. The technique has been shown to both quantify lung scarring and detect lung fluid in rats. A study on pulmonary edema in humans is under way.

Plant-Based Spray Could be Used in N95 Masks and Energy Devices

Engineers have invented a way to spray extremely thin wires made of a plant-based material that could be used in N95 mask filters, devices that harvest energy for electricity, and potentially the creation of human organs. The method involves spraying methylcellulose, a renewable plastic material derived from plant cellulose, on 3D-printed and other objects ranging from electronics to plants, according to a Rutgers-led study in the journal Materials Horizons.

Pulmonary Fibrosis Awareness Month Highlights Realities of Rare Disease

September’s Pulmonary Fibrosis Awareness Month shares crucial realities and insights about the rare disease, its symptoms and helpful resources provided by the Pulmonary Fibrosis Foundation to educate the public about this devastating disease which impacts over 200,000 Americans.

Severely Damaged Human Lungs Can Now Be Successfully Recovered

A multidisciplinary team from Columbia Engineering and Vanderbilt University has now demonstrated that severely injured donor lungs that have been declined for transplant can be recovered outside the body by a system that uses cross-circulation of whole blood between the donor lung and an animal host. For the first time, a severely injured human lung that failed to recover using the standard clinical EVLP was successfully recovered during 24 hours on the team’s cross-circulation platform.

Ribs evolved for movement first, then co-opted for breathing

A major transformation in vertebrate evolution took place when breathing shifted from being driven by head and throat muscles—like in fish and frogs—to the torso—like in reptiles and mammals. But what caused the shift? A new study posits that the intermediate step was locomotion—the mechanics follow the same pattern as inhalation and exhalation.

ATS Publishes New Guidance on COVID-19 Management

An American Thoracic Society-led international task force has released a guidance document to help clinicians manage COVID-19 patients in the face of a worldwide pandemic and minimal empirical evidence to guide treatment. The new guidance – “COVID-19: Interim Guidance on Management Pending Empirical Evidence”– is published as an open access document on the American Thoracic Society’s website.

Following the lizard lung labyrinth

Mammals inhale oxygen-rich air and they exhale depleted air, exhibiting a so-called tidal flow pattern. In contrast, bird breath travels through part of the respiratory system, but in a one-way loop throughout most of the lung. Biologists have discovered that Savannah monitor lizards have lung structures that are hybrid system of bird and mammal lungs.

Oils added to vaping products cause damage to lungs, expert says

In response to a new study which found that lung damage from vaping resembles chemical burns, Geraldine R. Britton, director of the Binghamton University Interdisciplinary Tobacco Use Research Program, offers the following. “Many have believed that the underlying problem with vaping…
