Micro-premature infants in New Jersey show improved mortality and morbidity from 2000-2018.

Background: Micro-premature newborns, gestational age (GA) ≤ 25 weeks, have high rates of mortality and morbidity. Literature has shown improving outcomes for extremely low gestational age newborns (ELGANs) GA ≤ 29 weeks, but few studies have addressed outcomes of ELGANs ≤ 25 weeks.

Objective: To evaluate the trends in outcomes for ELGANs born in New Jersey, from 2000 to 2018 and to compare two subgroups: GA 23 to 25 weeks (E1) and GA 26 to 29 weeks (E2).

Evaluation of critical congenital heart defects screening using pulse oximetry in the neonatal intensive care unit.

Objective: To evaluate the implementation of early screening for critical congenital heart defects (CCHDs) in the neonatal intensive care unit (NICU) and potential exclusion of sub-populations from universal screening.

Study Design: Prospective evaluation of CCHD screening at multiple time intervals was conducted in 21 NICUs across five states (n=4556 infants).

Results: Of the 4120 infants with complete screens, 92% did not have prenatal CHD diagnosis or echocardiography before screening, 72% were not receiving oxygen at 24 to 48 h and 56% were born ⩾2500 g.

Quantitative ultrasound in the evaluation of bone status in premature and full-term infants.

Metabolic bone disease of prematurity (MBDP) is a common and significant problem that often gives rise to osteopenia, fractures, osteomalacia, and osteoporosis. The purpose of our study is to establish normative data on bone status in premature and full-term infants to help future studies on MBDP. Bone status was prospectively determined as part of a multicenter study among newborns within 96 hours of life.

Nosocomial infections in the neonatal intensive care unit.

Nosocomial infections are significant causes of morbidity and mortality in patients who require newborn intensive care. The most common bacterial pathogens are Gram-positive bacteria, including Staphylococcus epidermidis, Staphylococcus aureus, and Enterococcus species. Gram-negative enteric bacilli and Gram-negative environmental bacteria are involved in outbreaks and occasional cases of nosocomial infection.

The role of neutrophils in the production of hypoxic-ischemic brain injury in the neonatal rat.

Neutrophils contribute to ischemic brain injury in adult animals. The role of neutrophils in perinatal hypoxic-ischemic (HI) brain injury is unknown. Allopurinol reduces neutrophil accumulation after tissue ischemia and is protective against HI brain injury.

Precise control of nitric oxide concentration in the inspired gas of continuous flow respiratory devices.

Inhaled NO has become widely used for diagnosis and therapy of pulmonary hypertension. The potential hazards of NO inhalation include the formation of methemoglobin, formation of NO2, and generation of free radicals in the presence of humidity and oxygen. Careful monitoring of NO and NO2 concentration, and titration of the dose according to a patient's clinical response is essential to minimize toxicity.

Nitric oxide reversal of recurrent pulmonary hypertension and respiratory failure in an infant with CDH after successful ECMO therapy.

Nitric oxide (NO) represents a new therapeutic modality for treating neonatal pulmonary hypertension and may obviate the need for extracorporeal membrane oxygenation (ECMO) in a number of cases of neonatal respiratory failure. Recently, the authors treated an infant with a congenital diaphragmatic hernia and pulmonary hypertension with NO on two separate occassions. During the initial period of stabilization, NO failed to reverse the pulmonary hypertension and prevent the development of progressive respiratory failure.

Contribution of genetic disorders to neonatal mortality in a regional intensive care setting.

We examined the contribution of chromosomal abnormalities, mendelian disorders, and birth defects to mortality in a regional neonatal intensive care unit by medical record review of neonatal deaths in that unit. Of a total of 296 infant deaths during the 5-year period June 1986 to May 1991, 69 (23.3%) had a genetic disorder.
