Intravenous magnesium in asthma pharmacotherapy: variability in use in the PECARN Registry.
Researchers examined the use, efficacy, and safety of intravenous magnesium sulfate (IVMg) in children with asthma whose emergency department (ED) management is recorded in the Pediatric Emergency Care Applied Research Network (PECARN) Registry. They found that, in PECARN Registry EDs, administration of IVMg occurred late in ED treatment, for a minority of the children likely to benefit, with variation between sites, which suggested the current clinical role for IVMg in preventing hospitalization was limited. Discharge after IVMg administration would likely be safe. They recommended further research to assess the efficacy and safety of early IVMg administration.

Anticholinergic vs long-acting beta-agonist in combination with inhaled corticosteroids in Black adults with asthma: the BELT randomized clinical trial.
The researchers compared the effectiveness and safety of tiotropium vs long-acting beta agonists (LABAs), when used with inhaled corticosteroids (ICS) in black adults with asthma. They found that among black adults with asthma treated with ICS, adding a LABA did not improve time to asthma exacerbation compared with adding tiotropium. These findings were not affected by polymorphisms at the Arg16Gly locus of ADRB2.
