Neonatal Abstinence Syndrome and Preterm Infants: A Look at Current Practice.

Background/significance: Intrauterine opioid drug exposure is associated with an increased risk of preterm birth. Preterm infants may not exhibit the same withdrawal symptoms as term infants diagnosed with neonatal abstinence syndrome (NAS). There are no current standards for how to screen, assess, or treat NAS in preterm infants.

Skeletal muscle adaptations in elastic resistance-trained young men and women.

Skeletal muscle adaptations (fiber-type composition, cross-sectional area, myosin heavy chain (MHC) content, and capillarity) were assessed in the vastus lateralis muscle of young men and women after 8 weeks of training with the Sportcord, an elastic resistance device. Ten men [mean (SD) age 20 (1.1) years] and 13 women [20 (1.
