Abstract
INTRODUCTION Neonates and infants who undergo congenital cardiac surgery frequently have difficulty with feeding. The factors that predispose these patients to require a gastrostomy tube have not been well defined. We aimed to report the incidence and describe hospital outcomes and characteristics in neonates and infants undergoing congenital cardiac surgery who required gastrostomy tube placement. MATERIALS AND METHOD A retrospective review was performed on patients undergoing congenital cardiac surgery between October 2015 and December 2020. Patients were identified by International Classification of Diseases 10th Revision codes, utilising the performance improvement database Vizient® Clinical Data Base, and stratified by age at admission: neonates (<1 month) and infants (1-12 months). Outcomes were compared and comparative analysis performed between admissions with and without gastrostomy tube placement. RESULTS There were 11,793 admissions, 3519 (29.8%) neonates and 8274 (70.2%) infants. We found an increased incidence of gastrostomy tube placement in neonates as compared to infants following congenital cardiac surgery (23.1% versus 6%, p = <0.001). Outcomes in neonates and infants were similar with increased length of stay and cost in those requiring a gastrostomy tube. Gastrostomy tube placement was noted to be more likely in neonates and infants with upper airway anomalies, congenital abnormalities, hospital infections, and genetic abnormalities. DISCUSSION Age at hospitalisation for congenital cardiac surgery is a definable risk factor for gastrostomy tube requirement. Additional factors contribute to gastrostomy tube placement and should be used when counselling families regarding the potential requirement of a gastrostomy tube.

Abstract
Prostaglandin E1 (PGE) is used in patients with ductal-dependent congenital heart disease (CHD). Side effects of apnea and fever are often dose dependent and occur within 48 h after initiation. We initiated a standardized approach to PGE initiation after our institution recognized a high incidence of side effects and a wide variety of starting doses of PGE. Neonates with prenatally diagnosed ductal-dependent CHD were identified, started on a standardized protocol that started PGE at 0.01 mcg/kg/min, and evaluated for PGE related side effects. Compliance, outcomes and dose adjustments during the first 48 h post-PGE initiation were evaluated. Fifty patients were identified (25 pre-intervention; 25 post-intervention). After intervention, compliance with the protocol was 96%, and apnea or fever occurred in 28% (compared to 63% pre-intervention, p = 0.015). Dose adjustments (either increase or decrease) prior to cardiac surgery were similar in both cohorts (60%, 52%, p = 0.569). There were no mortalities or emergent procedures performed due to ductus arteriosus closure. Standardizing a protocol for initiating PGE in prenatally diagnosed ductal-dependent CHD was successful and reduced the incidence of apnea, fever, and sepsis evaluations. A starting dose of 0.01 mcg/kg/min did not cause increased adverse effects.

Abstract
Gene conversion, the non-reciprocal exchange of genetic information, is one of the potential products of meiotic recombination. It can shape genome structure by acting on repetitive DNA elements, influence allele frequencies at the population level, and is known to be implicated in human disease. But gene conversion is hard to detect directly except in organisms, like fungi, that group their gametes following meiosis. We have developed a novel visual assay that enables us to detect gene conversion events directly in the gametes of the flowering plant Arabidopsis thaliana. Using this assay we measured gene conversion events across the genome of more than one million meioses and determined that the genome-wide average frequency is 3.5×10(-4) conversions per locus per meiosis. We also detected significant locus-to-locus variation in conversion frequency but no intra-locus variation. Significantly, we found one locus on the short arm of chromosome 4 that experienced 3-fold to 6-fold more gene conversions than the other loci tested. Finally, we demonstrated that we could modulate conversion frequency by varying experimental conditions.
