Under load-bearing conditions metal-based foam scaffolds are currently the preferred choice as bone/cartilage implants. In this study X-ray micro-computed tomography was used to discretize the three-dimensional structure of a commercial titanium foam used in spinal fusion devices. Direct finite element modeling, continuum micromechanics and analytical models of the foam were employed to characterize the elasto-plastic deformation behavior.

Background And Hypothesis: Psychosocial support programs have been established in view of the burden caused to parents having their newborn admitted to the neonatal intensive care unit (NICU). Due to limited resources, preventive programs can only be offered to parents who are identified by the staff to be at risk. Based on the results of a parent questionnaire, the University Children's Hospital Vienna has developed a standardized concept of integrated psychological support.

Patients And Methods: Infants with a GA of <30 weeks admitted to the neonatal intensive care unit of the Vienna University Children's Hospital (Vienna, Austria) were studied prospectively by using aEEG and cranial ultrasound. Clinically stable infants without clinical or sonographic evidence of neurologic abnormalities were eligible for inclusion in the reference group.
Unlabelled: Neonates are sensitive to pain and vulnerable to both its short-term and long-term effects. Management of analgesia is thought to be hampered by lack of awareness that newborns are capable of experiencing pain and by fears about adverse effects associated with analgesics. The purpose of this study was to assess current medical practice in preventive analgesia and sedation in the neonate throughout Austria.

Methods: Prospective cohort study during June 2001 and January 2002. Preterm infants < 33 + 6 weeks of gestation who had amniotic fluid and placental tissue sampled for culture during cesarean section were included.
