Background: The incidence of silicosis has increased due to occupational silica exposure from artificial stone, with no treatments proven to halt or reverse the disease. Whole lung lavage (WLL) involves the instillation of fluid into the lungs to wash out silica particles and disease-causing inflammatory cells. This study aimed to determine the feasibility, safety, and possible benefit of WLL in patients with artificial stone silicosis.

Specialized or secondary metabolites are small molecules of biological origin, often showing potent biological activities with applications in agriculture, engineering and medicine. Usually, the biosynthesis of these natural products is governed by sets of co-regulated and physically clustered genes known as biosynthetic gene clusters (BGCs). To share information about BGCs in a standardized and machine-readable way, the Minimum Information about a Biosynthetic Gene cluster (MIBiG) data standard and repository was initiated in 2015.

Terrestrial actinomycetes in the genus have long been recognized as prolific producers of small-molecule natural products, including many clinically important antibiotics and cytotoxic agents. Although can also be isolated from marine environments, their potential for natural product biosynthesis remains underexplored. The MAR4 clade of largely marine-derived has been a rich source of novel halogenated natural products of diverse structural classes.

Background: Expert airway management is an essential skill for pulmonary and critical care fellows. Providing high-quality real-time feedback to trainees performing emergent intubations is often limited because of the acuity of the situation and the lack of full airway visualization by the supervising provider.

Objective: We sought to improve the quality of airway management education in a pulmonary and critical care fellowship training program by recording all emergent intubations and systematically reviewing select videos at a regularly scheduled airway management conference.
