Salient early intervention approaches for children below the age of 3 years, such as home visiting, seek to strengthen the pivotal role that parents play in fostering their young children's early learning. Yet, measures that identify and monitor the ways in which low-income parents support toddlers' learning experiences are lacking. Without parent involvement measures for toddlers, evidence-based advancement of home visiting with regard to this key outcome is restricted. This study undertook a mixed-method approach to obtain perceptions of involvement behaviors from ethnic minority home visitors who were associated with a national home visiting program and to translate these perceptions into a meaningful, preliminary measure for children aged 2 and 3 years. Named the Parent Involvement in Early Learning scale, a statistical approach combining classical test and item response theories produced preliminary single dimensions of home-based involvement for the English and Spanish translations. This study is presented as a first step in raising awareness of parent involvement for this age group and directing future research.

We investigated the possibility that hearing thresholds are altered in prenatally stressed rats raised in a normal auditory environment. Pregnant dams were assigned randomly to prenatally stressed and control groups. Half of the dams were subjected to the mild stressors of handling, exposure to a novel cage and saline injection at random times during lights-on daily. The hearing thresholds of young adult male offspring were assessed by recording auditory-evoked brainstem responses to 0.5, 1, 2, 4, 8, 16, 32 and 64 kHz pure tones. The resultant audiograms showed that prenatally stressed offspring had significantly higher hearing thresholds than control animals at 1, 2 and 4 kHz (t-tests, P<0.05). The threshold shifts caused by prenatal stress averaged 7.7 dB across frequencies. We conclude that prenatal stress causes low-frequency hearing loss, possibly due to increased vulnerability to noise-induced hearing loss, accelerated cochlear degeneration and/or disrupted cochlear development.

There were no differences in the rate of PD or other adverse outcomes. Hypotension occurred more frequently with CSE during labor at term. The study supports both EPI and CSE during labor as safe and effective techniques for neuraxial analgesia.
