Background: Hospital care for neonates can be challenging for parents, and a negative parental experience can affect the well-being of the infant after discharge. A family-centred approach is the gold standard of care in neonatology.

Aim: This study aimed to identify common themes in voluntary unstructured feedback received from parents and caregivers of infants admitted to the neonatal intensive care unit, special care nursery or postnatal ward or followed up by neonatal outpatient services at a tertiary Australian Women and Children's Hospital.

Interferon gamma (IFN) is a potent antiviral cytokine that can be produced by many innate and adaptive immune cells during infection. Currently, our understanding of which cells produce IFN and where they are located at different stages of an infection is limited. We have used reporter mice to investigate expression of mRNA in the lung and secondary lymphoid organs during and following influenza A virus (IAV) infection.

Domains are instrumental in facilitating protein interactions with DNA, RNA, small molecules, ions and peptides. Identifying ligand-binding domains within sequences is a critical step in protein function annotation, and the ligand-binding properties of proteins are frequently analyzed based upon whether they contain one of these domains. To date, however, knowledge of whether and how protein domains interact with ligands has been limited to domains that have been observed in co-crystal structures; this leaves approximately two-thirds of human protein domain families uncharacterized with respect to whether and how they bind DNA, RNA, small molecules, ions and peptides.

Aim: Sepsis is multifactorial and potentially devastating for preterm neonates. Changes in surfactant protein-D (SP-D), phosphatidylcholine (PC) and PC molecular species during infection may indicate innate immunity or inflammation during sepsis. We aimed to compare these important pulmonary molecules in ventilated neonates without or with sepsis.

Background: Over the last decade, a number of studies have demonstrated that early division of tongue-tie (TT) is associated with significant feeding benefits to both mother and baby. Notwithstanding, it remains a controversial procedure. We examined the breastfeeding outcomes of a cohort of babies at 1-2 weeks (follow-up 1) and 3-5 months (follow-up 2), post-TT division.

Article Synopsis
  • Invasive ventilation assists breathing but can lead to complications since it bypasses natural airway functions; thus, warming and humidifying inhaled gases is essential.
  • Two primary methods for humidification during mechanical ventilation—heat and moisture exchangers (HME) and heated humidifiers (HH)—are compared for effectiveness in preventing complications.
  • This review assesses trials to determine which method is better while considering factors like age, duration of humidification, type of HME, and tracheostomy ventilation.

An OMS office is a complex environment. Within such an environment, a diverse scope of complex surgical procedures is performed with different levels of anesthesia, ranging from local anesthesia to general anesthesia, on patients with varying comorbidities. Optimal patient outcomes require a functional surgical and anesthetic team, who are familiar with both standard operational principles and emergency recognition and management.

Background: A previous randomised controlled trial (RCT) in babies born < 30 weeks gestation found the so-called CICADA method (ceasing continuous positive airways pressure (CPAP) with a view to remain off rather than slow weaning) significantly reduced CPAP time. Post-RCT we introduced the CICADA method and evaluated whether the improved outcomes of the CICADA method during the RCT were replicated in clinical practice.

Aim: The aim of the study is to compare cardio-respiratory outcomes in PBs < 30 weeks GA over three epochs: (i) pre RCT, (ii) during RCT and (iii) post RCT implementation.

The nickel-catalyzed coupling of enones or enals with alkynes in the presence of silane and titanium alkoxide reductants provides direct access to skipped diene products. The process involves a net four-electron reductive coupling and proceeds with deoxygenation of the starting enone or enal. A new class of well-defined nickel(0) precatalysts bearing an unhindered N-heterocyclic carbene ligand, which was developed in optimization of the process, is essential for the efficiency of the transformation.

Unlabelled: This is a retrospective analysis of a multicentre randomised controlled trial (RCT) where we concluded that CeasIng Cpap At standerD criteriA (CICADA) in premature babies (PBs) <30 weeks gestational age (GA) was the significantly better method of ceasing CPAP. To identify factors that may influence the number of attempts to cease CPAP, we reviewed the records of 50 PBs from the RCT who used the CICADA method. PBs were grouped according to number of attempts to cease CPAP (fast group ≤2 attempts and slow group >2 attempts to cease CPAP).

Background: In 2011, the Centenary Hospital Neonatal Department guidelines were modified and recommended delaying the division of infant tongue-tie (TT) until after 7 days of life. This paper looks at the effect of these guidelines in practice by comparing patient characteristics and breastfeeding practices before and after the change.

Methods: We used prospective data from mothers and babies who had TT division to compare breastfeeding practices in 2008 and 2011.
