Outcomes of community-acquired pneumonia using the Pneumonia Severity Index the CURB-65 in routine practice of emergency departments.

Background: The Pneumonia Severity Index (PSI) and the CURB-65 score assess disease severity in patients with community-acquired pneumonia (CAP). We compared the clinical performance of both prognostic scores according to clinical outcomes and admission rates.

Methods: A nationwide retrospective cohort study was conducted using claims data from adult CAP patients presenting to the emergency department (ED) in 2018 and 2019.

The impact on central line-associated bloodstream infection rates following the introduction of a closed system transfer device in oncology wards.

Prevention of hazardous drug exposure is essential in averting unnecessary health risks to health care workers (HCW). To address the risk to HCWs when handling hazardous drugs, engineering controls can be utilized to reduce the exposure. A closed system transfer device (CSTD) was introduced for hazardous drugs administration in 6 oncology wards; this new CSTD was associated with a significant increase in CLABSI rates.

A polarized supercell produces specialized metabolites in cannabis trichomes.

For centuries, humans have cultivated cannabis for the pharmacological properties that result from consuming its specialized metabolites, primarily cannabinoids and terpenoids. Today, cannabis is a multi-billion-dollar industry whose existence rests on the biological activity of tiny cell clusters, called glandular trichomes, found mainly on flowers. Cannabinoids are toxic to cannabis cells, and how the trichome cells can produce and secrete massive quantities of lipophilic metabolites is not known.

Volume determination methods for hematopoietic progenitor cell products collected by apheresis.

Background Aims: CD34 cell count of hematopoietic progenitor cell products is often first determined using a product sample, with the final reported cell count obtained by multiplying cell count from the sample by the total product volume. Product volume may be determined by apheresis instruments used for collection or calculated based on specific gravity (SG). Here the authors sought to determine the discrepancies between these methods and the impact on patient care.

Cannabis glandular trichomes alter morphology and metabolite content during flower maturation.

The cannabis leaf is iconic, but it is the flowers of cannabis that are consumed for the psychoactive and medicinal effects of their specialized metabolites. Cannabinoid metabolites, together with terpenes, are produced in glandular trichomes. Superficially, stalked and sessile trichomes in cannabis only differ in size and whether they have a stalk.
