Randomized Controlled Trial Multicenter Study
Relative effectiveness of additive pain interventions during vaccination in infants.
Vaccine injections can cause acute pain and distress in infants, which can contribute to dissatisfaction with the vaccination experience and vaccine hesitancy. We sought to compare the effectiveness of additive pain interventions administered consistently during vaccine injections in the first year of life. ⋯ Only liposomal lidocaine provided consistent analgesia within an additive pain intervention regimen during vaccinations in infants. Trial registration: ClinicalTrials.gov, no. NCT01503060.

Although aggregate data suggest a link between snowfall and myocardial infarction (MI), individual risk has yet to be assessed. We evaluated the association between quantity and duration of snowfall and the risk of MI using nonaggregated administrative health data. ⋯ Both the quantity and duration of snowfall were associated with subsequent risk of hospital admission or death due to MI, driven primarily by an effect in men. These data have implications for public health initiatives in regions with snowstorms.
