Title: Follow-up Visit of High Risk Infants
Brief Summary: The NICHD Neonatal Research Network's Follow-Up study is a multi-center cohort in which surviving extremely low birth-weight infants born in participating network centers receive neurodevelopmental, neurosensory and functional assessments at 22-26 months corrected age (Infants born prior to July 1, 2012 were seen at 18-22 months corrected age). Data regarding pregnancy and neonatal outcome are collected prospectively. The goal is to identify potential maternal and neonatal risk factors that may affect infant neurodevelopment.

* Premature infants who does not improve the breathing or worse within 24 hours prior to enrollment of this study
* Written consent form signed by a legal representative or a parent

Exclusion Criteria:

* Cyanotic or acyanotic congenital heart diseases except patent ductus arteriosus

B: Inclusion Criteria:

* Mothers must have consented for cord blood collection at delivery
* cord blood must be available for extraction of stem cells.
* \>34 weeks gestation
* cord or neonatal pH\<7.0 or base deficit\>16 milliequivalents per liter (mEq/L) or history of acute perinatal event
* either a 10 minute Apgar \< 5 or continued need for ventilation.
* All infants must have signs of encephalopathy within 6 hours of age.

Exclusion Criteria:

* Inability to enroll by 14 days of age.
* Presence of known chromosomal anomaly.
* Presence of major congenital anomalies.
* Severe intrauterine growth restriction (weight \<1800g)
* Infants in extremis for whom no additional intensive therapy will be offered by attending neonatologist.
* Parents refuse consent.
* Attending neonatologist refuses consent.
* Failure to collect the infant's cord blood and/or laboratory unable to process cord blood.
C: Inclusion Criteria:

* all Infants who enrolled in the Phase 1 PNEUMOSTEM® clinical trial (NCT01297205)

Exclusion Criteria:

* Infants whose parent or legal guardian did not want to participate in the study
D: * Infants inborn at NRN centers
* \<27 weeks gestational age
* Infants enrolled in one or more additional NICHD NRN Follow-up studies. For infants that do not meet the inclusion criteria above, inclusion and exclusion criteria are determined by the criteria for the additional trial(s). In these cases, infants that are larger than 1,000 grams and/or older than 27 weeks may be included in the FU Study.

Note: These inclusion criteria were changed as of 1/1/2008. Prior to this date, infants with birth weights between 401 and 1500 grams who were admitted to NRN NICUs within 14 days of birth were included in the database.
