O’Leary and colleagues conducted a population-based study of 10 897 sibling pairs aged 5 to 6 years using Early Development Instrument (a population-based measure of child development before primary school entry) data for Ontario, Canada, and found no differences in the adjusted odds of early developmental vulnerability or scores in major developmental domains between biological siblings when children were exposed to surgical procedures that required general anesthesia.

Morgan and colleagues conducted a cross-sectional analysis of survey data from 5241 respondents to Behavioral Risk Factor Surveillance System surveys and found that 30% of children in Washington state lived in firearm-owning households, an estimated 55% of whom lived with an unsafely stored firearm. Firearms were 20% more likely to be stored unsafely in homes with an adult who misused alcohol.

Tubbs-Cooley and colleagues conducted a study of 136 nurses caring for 418 infants during 332 shifts. They found that an increased infant-to-nurse ratio during a shift was associated with increased missed nursing care in about half of the measured missed care items. When a measure of subjective workload was considered, the associations of ratios were mostly attenuated; an increased subjective workload was consistently associated with increased missed care.
