Successful establishment and five-year sustainability of a neonatal-specific antimicrobial stewardship program in a low middle-income country.

Antibiotic use varies substantially among neonatal intensive care units (NICUs) without any appreciable impact on outcomes. An increased use of antimicrobials has been reported in low-middle income countries. This raises the concern for potential overuse of antibiotics in a fragile patient population, thus increasing the rates of multidrug resistant organisms and affecting the developing microbiome.

High-Dose Levetiracetam for Neonatal Seizures: A Retrospective Review.

Background: Neonatal seizures are frequently encountered in the neonatal intensive care unit and may be associated with serious long-term neurological sequelae. Response to treatment continues to be modest, and treatment guidelines remain unclear. The use of levetiracetam has been on the rise in the past several years due to its favorable safety profile in the face of limited data on its efficacy and optimal dosing regimens.

Increased Severity of Neonatal Abstinence Syndrome Associated With Concomitant Antenatal Opioid and Benzodiazepine Exposure.

Background: Polysubstance use is common among opioid-using women, yet its association with pharmacotherapy for neonatal abstinence syndrome (NAS) remains unclear. We hypothesized that benzodiazepine exposure would increase risk of an infant developing pharmacologically treated NAS.

Methods: We conducted a retrospective cohort study of maternal-infant dyads enrolled in Tennessee Medicaid, using individual-level data linkage of vital records and administrative (ie, outpatient, inpatient, and prescription) data from 2009 to 2011.

Positive Predictive Value of Administrative Data for Neonatal Abstinence Syndrome.

Objectives: Neonatal abstinence syndrome (NAS) is a postnatal withdrawal syndrome experienced by some infants with opioid exposure. Hospital administrative data are commonly used for research and surveillance but have not been validated for NAS. Our objectives for this study were to validate the diagnostic codes for NAS and to develop an algorithm to optimize identification.

Outpatient Pharmacotherapy for Neonatal Abstinence Syndrome.

Objective: To determine differences in lengths of stay, length of therapy, emergency department (ED) utilization, and hospital readmissions between infants with neonatal abstinence syndrome (NAS) treated exclusively with inpatient pharmacotherapy compared with those discharged on outpatient pharmacotherapy.

Study Design: This retrospective cohort study of infants enrolled in the Tennessee Medicaid program used administrative and vital records data from 2009 to 2011. Medical record review was used to confirm cases of NAS and classify treatment type.

The opioid epidemic and neonatal abstinence syndrome in the USA: a review of the continuum of care.

As the prescription opioid epidemic grew in the USA, its impact extended to pregnant women and their infants. This review summarises how increasing rates of neonatal abstinence syndrome resulted in a need to improve care to pregnant women and opioid-exposed infants. We discuss the variations in care delivery with particular emphasis on screening at-risk mothers, scoring systems for neonatal drug withdrawal, type and duration of pharmacotherapy, and discharge safety.

Type IV collagen drives alveolar epithelial-endothelial association and the morphogenetic movements of septation.

Background: Type IV collagen is the main component of the basement membrane that gives strength to the blood-gas barrier (BGB). In mammals, the formation of a mature BGB occurs primarily after birth during alveologenesis and requires the formation of septa from the walls of the saccule. In contrast, in avians, the formation of the BGB occurs rapidly and prior to hatching.

Congenital diaphragmatic hernia interval on chromosome 8p23.1 characterized by genetics and protein interaction networks.

Chromosome 8p23.1 is a common hotspot associated with major congenital malformations, including congenital diaphragmatic hernia (CDH) and cardiac defects. We present findings from high-resolution arrays in patients who carry a loss (n = 18) or a gain (n = 1) of sub-band 8p23.

Congenital diaphragmatic hernia candidate genes derived from embryonic transcriptomes.

Congenital diaphragmatic hernia (CDH) is a common (1 in 3,000 live births) major congenital malformation that results in significant morbidity and mortality. The discovery of CDH loci using standard genetic approaches has been hindered by its genetic heterogeneity. We hypothesized that gene expression profiling of developing embryonic diaphragms would help identify genes likely to be associated with diaphragm defects.
