Engineers at Atlanta-based Georgia Tech’s Center for 3D Medical Fabrication have developed a 3D-printed tracheal splint as an airway for children born with a rare condition known as tracheal agenesis or the absence of a trachea or windpipe.

Studies published this week have introduced a consensus-based definition of long COVID-19 in children and young persons, narrowing its prevalence estimates, which have been wildly divergent. Long COVID rates for adults are still unclear, but a recent meta-analysis estimated that between one third and two thirds of adult COVID-19 patients who had severe acute disease develop symptoms of long COVID.

Japanese researchers have created complex 3D kidney organoids that could lead the way to better kidney research and even artificial kidneys for human transplant.

Combining Sarepta Therapeutics Inc.’s gene editing technology and Genedit Inc.’s Nanogalaxy platform to treat neuromuscular disorders shows promising potential, the companies reported. A year into the research collaboration, Genedit’s polymer nanoparticles have demonstrated the ability to deliver therapeutic cargo to specific muscle tissue following system administration of targeted genetic medicines.

PARIS – An interdisciplinary academic research consortium in Italy has devised and tested nanowires that restore physiological cell-to-cell conductance. This research team, led by the Experimental and Applied Medical Technology Lab (Tecmed Lab) at the Department of Medicine and Surgery at the University of Parma, Italy, has just published the results of multiple local in situ injections of nanowires into left ventricular infarct regions in Nature Communications.

South Korea’s Gwangju Institute of Science and Technology (GIST) has completed a preclinical study for a noninvasive therapy for Alzheimer’s disease. The "ultrasound-based gamma entrainment” technique involves syncing up gamma waves, or brain waves above 30 Hz, with an external oscillation of a given frequency. This happens naturally by exposing a subject to a repetitive stimulus, such as sound, light, or mechanical vibrations.

A study by researchers led by David James from the University of Sydney showcases the diversity in metabolic responses observed across different mouse strains exposed to two different diets that demonstrates the heritability of metabolic traits.

A team led by researchers from the ETH Zürich and the University of Basel has used a combination of mass spectrometry data and machine learning to predict antibiotic resistance of clinical bacterial samples. The results, which were published in the Jan. 10, 2022, issue of Nature Medicine, could speed the identification of optimal antibiotic regimens for patients.

Researchers at the Peter Doherty Institute for Infection and Immunity, the University of Queensland, Griffith University, the University of Adelaide and St. Jude Children's Research Hospital have unlocked a key to making existing front-line antibiotics work again against Streptococcus pneumoniae, the bacteria that cause pneumonia.

Clinicians at the University of Maryland have transplanted a heart from a genetically modified pig bred by Revivicor Inc., a subsidiary of United Therapeutics Corp., into a patient with end-stage heart failure.
