Evaluation of hospital nurses' perceived knowledge and practices of venous thromboembolism assessment and prevention.

Venous thromboembolism (VTE) is a preventable cause of hospital death. Bedside registered nurses (RNs) are a key group that can be the first to recognize risks of patients in acute care settings. The purpose of this study was to identify bedside hospital RNs' perceived knowledge of VTE, their assessment practices, their self-efficacy in conducting VTE prevention care, and their perceived barriers to performing VTE risk assessment.

Growth factors, inflammatory cytokines and postnatal bone strength in preterm infants.

Aim: To assess the relationships between growth factors, inflammatory cytokines and postnatal bone development in preterm infants.

Methods: Fifty premature infants (24-32 weeks gestational age, mean birth weight: 1,024 +/- 50 g) participated in the study. Bone strength was determined weekly by quantitative ultrasound measurements of bone speed of sound (SOS).

Body composition and its components in preterm and term newborns: A cross-sectional, multimodal investigation.

A prospective, cross-sectional, observational study in preterm and term infants was performed to compare multimodal measurements of body composition, namely, limb ultrasound, bone quantitative ultrasound, and dual X-ray absorptiometry (DXA). One hundred and two preterm and term infants appropriate for gestational age were enrolled from the newborn nursery and neonatal intensive care unit. Infants were included when they were medically stable, in an open crib, on full enteral feeds and within 1 week of anticipated discharge.

Inflammatory and growth mediators in growing preterm infants.

Little is understood about the optimal balance between IGF-I and antagonistic inflammatory mediators, such as IL-6, in growing preterm infants. Using a prospective cohort study, we investigated the relationship between postnatal growth of preterm infants and key growth and inflammatory mediators. We studied 51 stable, growing preterm infants (mean gestational age: 27.
