Getting Up to Speed: Rapid Pathogen and Antimicrobial Resistance Diagnostics in Sepsis.

Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection. Time to receive effective therapy is a primary determinant of mortality in patients with sepsis. Blood culture is the reference standard for the microbiological diagnosis of bloodstream infections, despite its low sensitivity and prolonged time to receive a pathogen detection.

A scoping review study of patients with a primary immune deficiency who have presented to the paediatric emergency department with a fever.

Aim: To identify, analyse, and synthesise existing research on the characteristics and risk factors associated with primary immune deficiencies (PIDs), with focus on understanding how factors impede patient outcomes.

Background: There is currently limited research regarding the management of this cohort when they present to an emergency department with the presentation urgency often being overlooked.

Method: Three databases, google scholar, and citations were searched for relevant studies under the criteria.

Global Lung Function Initiative reference values for multiple breath washout indices.

Background: Multiple breath washout is a lung function test based on tidal breathing that assesses lung volume and ventilation distribution. The aim of this analysis was to use the Global Lung Function Initiative methodology to develop all-age reference equations for the multiple breath washout indices lung clearance index (LCI) and functional residual capacity (FRC).

Methods: Multiple breath washout data from healthy individuals were collated from sites.

Crying wolf, alarm safety and management in paediatrics: A scoping review.

Aim: To provide a contemporaneous evidentiary overview of neonatal and paediatric studies investigating alarm-related patient safety and alarm system management. Furthermore, to describe how clinical alarm burden is captured and reported, to identify clinical devices that contribute to alarm burden, to explore alarm-related and patient safety measures and terminologies and to review alarm management initiatives.

Design: Scoping review.

Invasive fungal disease and antifungal prophylaxis in children with acute leukaemia: a multicentre retrospective Australian cohort study.

Background: Invasive fungal disease (IFD) is a significant complication for children receiving treatment for leukaemia, contributing to morbidity and mortality. Recent regional paediatric epidemiological IFD data are lacking. Additionally uncertainty remains regarding the optimal prophylactic approach in this context.

Predicting hospital bed utilisation for post-surgical care by means of the Monte Carlo method with historical data.

Objective This study aim was to develop a predictive model of bed utilisation to support the decision process of elective surgery planning and bed management to improve post-surgical care. Methods This study undertook a retrospective analysis of de-identified data from a tertiary metropolitan hospital in Southeast Queensland, Australia. With a reference sample from 2years of historical data, a model based on the Monte Carlo method has been developed to predict hospital bed utilisation for post-surgical care of patients who have undergone surgical procedures.

Preferred Treatment Patterns of Retinopathy of Prematurity: An International Survey.

This paper assesses the preferred treatment patterns for retinopathy of prematurity (ROP) and examine trends in anti-vascular endothelial growth factor (VEGF) use for ROP. : A retrospective survey consisting of 14 questions was distributed to paediatric ophthalmology interest groups internationally. Main outcome measures included treatment patterns, proportion of anti-VEGF use in different stages of ROP; and comparison of first-line treatments as well as repeat anti-VEGF treatments.

The Australian Genomics Mitochondrial Flagship: A national program delivering mitochondrial diagnoses.

Purpose: Families living with mitochondrial diseases (MD) often endure prolonged diagnostic journeys and invasive testing, yet many remain without a molecular diagnosis. The Australian Genomics Mitochondrial Flagship, comprising clinicians, diagnostic, and research scientists, conducted a prospective national study to identify the diagnostic utility of singleton genomic sequencing using blood samples.

Methods: A total of 140 children and adults living with suspected MD were recruited using modified Nijmegen criteria (MNC) and randomized to either exome + mitochondrial DNA (mtDNA) sequencing or genome sequencing.

Incidence and presenting features of paediatric type 1 diabetes mellitus and diabetic ketoacidosis in a regional Australian health service.

Aim: To determine the incidence and presenting features of type 1 diabetes mellitus and diabetic ketoacidosis in a paediatric population serviced by a regional health service in Queensland, Australia.

Methods: All patients less than 16 years old diagnosed with type 1 diabetes mellitus between 01 January 2015 and 31 December 2021 were included in this retrospective, observational study. The electronic medical records of each patient were reviewed to collect data on demographics, presentation and ongoing diabetes care.

The seroprevalence of SARS-CoV-2-specific antibodies in Australian children: A cross-sectional study.

Background: Following reduction of public health and social measures concurrent with SARS-CoV-2 Omicron emergence in late 2021 in Australia, COVID-19 case notification rates rose rapidly. As rates of direct viral testing and reporting dropped, true infection rates were most likely to be underestimated.

Objective: To better understand infection rates and immunity in this population, we aimed to estimate SARS-CoV-2 seroprevalence in Australians aged 0-19 years.

Synchronous intracranial arteriovenous malformation and papillary glioneuronal tumour: hypothesis or reality?

Brain arteriovenous malformations (AVM) rarely occur with spatial and/or temporal co-localisation to intracranial neoplasms. Most prior reports describe this association with high-grade gliomas; however, reports of a co-occurrence with low grade gliomas are very rare. It is unclear whether such cases represent a true co-occurrence of separate pathologies or simply an unusually vascular phenotype of the neoplasm.

Serum ganciclovir drug exposure in children receiving standard ganciclovir dosing.

Intravenous ganciclovir (GCV) is used for the treatment of cytomegalovirus (CMV) infection in immunocompromised children. Although the therapeutic target for treatment is unclear, studies have shown a serum area under the concentration-time curve (AUC) ≥40 mg/L·h correlates with effective CMV prevention. This study aimed to externally validate existing GCV population pharmacokinetic (PopPK) models and develop a model if needed and evaluate the serum AUC achieved with standard GCV dosing and propose an optimized dosing strategy for immunocompromised children.

Arterial dissection in scuba divers: a potential adverse manifestation of the physiological effects of immersion.

Introduction: Aortic dissections and dissections of cervical, cerebral, and coronary arteries have been previously reported in scuba divers. These incidents may be the consequence of a variety of physiological effects. We review the reported cases of arterial dissection in scuba divers and discuss potential contributing factors related to immersion and diving.

Short-term Outcomes in Infants after General Anesthesia with Low-dose Sevoflurane/Dexmedetomidine/Remifentanil versus Standard-dose Sevoflurane (the TREX Trial).

Background: The Trial Remifentanil DEXmedetomidine (TREX) trial aimed to determine whether, in children less than 2 yr old, low-dose sevoflurane/dexmedetomidine/remifentanil anesthesia is superior to standard-dose sevoflurane anesthesia in terms of global cognitive function at 3 yr of age. The aim of the current secondary analyses was to compare incidence of intraoperative hypotension and bradycardia, postoperative pain, time to recovery, need for treatment of intraoperative hypotension and bradycardia, incidence of light anesthesia and need for treatment, need for postoperative pain medications, and morbidity and mortality outcomes at 5 days between the two arms.

Methods: This phase III randomized active controlled, parallel group, assessor blinded, multicenter, superiority trial was performed in 20 centers in Australia, Italy, and the United States.

Slow growth and short stature in children with attention deficit hyperactivity disorder (ADHD): a retrospective study of 493 children who underwent growth hormone provocation testing at one tertiary paediatric endocrine centre.

Objectives: We hypothesised that growth hormone (GH) deficiency (GHD) in children with attention deficit hyperactivity disorder (ADHD) is rare. This study aimed to determine any distinct clinical or biochemical parameters, including GH provocation testing, in children with ADHD on psychostimulants or idiopathic short stature (ISS).

Methods: Retrospective cross-sectional study of children who had GH provocative testing between 1998 and 2013 at one tertiary paediatric endocrine centre.

Nutritional Management of Pediatric Gastrointestinal Motility Disorders.

Normal and optimal functioning of the gastrointestinal tract is paramount to ensure optimal nutrition through digestion, absorption and motility function. Disruptions in these functions can lead to adverse physiological symptoms, reduced quality of life and increased nutritional risk. When disruption or dysfunction of neuromuscular function occurs, motility disorders can be classified depending on whether coordination or strength/velocity of peristalsis are predominantly impacted.

Urinary chloride excretion in critical illness and acute kidney injury: a paediatric hypothesis-generating cohort study post cardiopulmonary bypass surgery.

Renal chloride metabolism is currently poorly understood but may serve as both a diagnostic and a treatment approach for acute kidney injury. We investigated whether plasma chloride, ammonia and glutamine as well as urinary chloride, ammonium and glutamine concentrations may serve as markers for acute kidney injury in paediatric patients. We conducted a prospective observational trial in a tertiary care paediatric intensive care unit.
