Abstract& Researchers have long debated whether knowledge about the self is unique in terms of its functional anatomic representation within the human brain. In the context of memory function, knowledge about the self is typically remembered better than other types of semantic information.

OBJECTIVE To investigate the effect of sunflower seed oil (SSO) and almond oil (AO) on stratum corneum hydration and Neonatal Skin Condition Scores (NSCSs) of preterm infants. METHODS This randomized controlled trial recruited 90 preterm infants whose gestational ages were between 32 and 37 weeks in the neonatal ICU. Infants were randomly assigned to three groups (SSO, AO, or control). The oils were applied to the whole body of each infant except for the head and face by a nurse researcher four times a day (4 mL/kg) for 5 days. MAIN OUTCOME MEASURES Skin condition of the infants as evaluated with the NSCS; hydration as measured by a skin moisture meter before and after application. MAIN RESULTS When average stratum corneum hydration was compared, infants in the SSO and AO groups had better hydration than infants in the control group. The NSCS scores in the control group were significantly higher than in the intervention groups, but there was no difference between the SSO and AO groups. CONCLUSIONS Neither SSO nor AO has harmful effects on the skin, and their use may improve stratum corneum hydration. These oils can be used by nurses to hydrate the skin of preterm infants. Further studies are needed to evaluate the efficacy of natural oils on infant skin.
