Repeat testing with a rapid antigen test may be required to rule out SARS-CoV-2 infection

A prospective cohort study has found that repeat testing in 48-hour intervals with a rapid antigen test (Ag-RDT) may be required to rule out SARS-CoV-2 infection. This means that people testing for SARS-CoV-2 should exercise caution in public settings despite an initial negative result if they suspect they may be infected or have been exposed. The findings are published in Annals of Internal Medicine.

State medical cannabis laws not associated with reduced use of opioid or non-opioid pain treatments, finds study

A study of commercially insured adults with chronic non-cancer pain has found that state medical cannabis laws did not affect receipt of opioid or non-opioid pain treatment. These findings suggest that cannabis use has not led to large shifts in pain treatment patterns at the population level. The study is published in Annals of Internal Medicine.
