Cohort study to evaluate the effect of vitamin D, magnesium, and vitamin B in combination on progression to severe outcomes in older patients with coronavirus (COVID-19).

Objectives: The aim of this study was to determine clinical outcomes of older patients with coronavirus (COVID-19) who received a combination of vitamin D, magnesium, and vitamin B (DMB) compared with those who did not. We hypothesized that fewer patients administered this combination would require oxygen therapy, intensive care support, or a combination of both than those who did not.

Methods: This was a cohort observational study of all consecutive hospitalized patients ≥50 y of age with COVID-19 in a tertiary academic hospital.

Urgent Delivery - Validation and Operational Implementation of Urgent Blood Delivery by Modern High Speed Hospital Pneumatic Tube System to Support Bleeding Emergencies Within a Hospital Massive Transfusion Protocol.

Background: Timely blood delivery to patients with critical bleeding poses logistic challenges. A modern, high speed hospital pneumatic tube system (PTS) is one solution, but blood units may be subjected to high-speed torque and acceleration/deceleration forces.

Objective: To validate a new PTS system for potential use at our 1,400-bed hospital in Singapore.
