Protocol for the diagnostic performance of C reactive protein, procalcitonin and interleukin-6 for serious bacterial infections among children ≤36 months old presenting with fever without source: a systematic review and meta-analysis.

Introduction: The management of fever without source in children ≤36 months old remains a diagnostic challenge as the underlying aetiologies can vary from self-limiting viral infections to serious bacterial infections (SBIs). Biomarkers such as C reactive protein (CRP), procalcitonin (PCT) and interleukin-6 (IL-6) have varying thresholds in the prediction of SBIs due to differences in SBI definitions, SBI prevalence, patient characteristics and timing of presentation. This protocol describes a systematic review and meta-analysis that aims to determine the thresholds at which CRP, PCT and IL-6 can perform optimally in distinguishing the presence of SBIs in children ≤36 months old, as well as to determine their performances in early detection of bacterial infections within 48 hours of fever onset.

Early metabolic derangements and unfavorable outcomes in pediatric traumatic brain injury: a retrospective multi-center cohort study.

Background: To study the association in moderate and severe pediatric traumatic brain injury (TBI) between hyperglycemia, hyperlactatemia, acidosis and unfavorable outcome, as assessed by Pediatric Cerebral Performance Category (PCPC) on discharge from the pediatric intensive care unit (PICU).

Methods: Children <16 years old with TBI and Glasgow Coma Scale (GCS) ≤13 in an Asian multi-center PICU TBI cohort from January 2014 to October 2017 were included in this study. We defined unfavorable outcome as PCPC ≥3-moderate disability, severe disability, vegetative state, and death.

Do paediatric early warning systems reduce mortality and critical deterioration events among children? A systematic review and meta-analysis.

Aim: We conducted a systematic review and meta-analysis to answer the question: Does the implementation of Paediatric Early Warning Systems (PEWS) in the hospital setting reduce mortality, cardiopulmonary arrests, unplanned codes and critical deterioration events among children, as compared to usual care without PEWS?

Methods: We conducted a comprehensive search using Medline, EMBASE, Cochrane Central Register of Controlled Trials, Cumulative Index to Nursing and Allied Health Literature and Web of Science. We included studies published between January 2006 and April 2022 on children <18 years old performed in inpatient units and emergency departments, and compared patient populations with PEWS to those without PEWS. We excluded studies without a comparator, case control studies, systematic reviews, and studies published in non-English languages.

Redesigning therapies for pantothenate kinase-associated neurodegeneration.

Pantothenate kinase-associated neurodegeneration (PKAN) is an incurable rare genetic disorder of children and young adults caused by mutations in the PANK2 gene, which encodes an enzyme critical for the biosynthesis of coenzyme A. Although PKAN affects only a small number of patients, it shares several hallmarks of more common neurodegenerative diseases of older adults such as Alzheimer's disease and Parkinson's disease. Advances in etiological understanding and treatment of PKAN could therefore have implications for our understanding of more common diseases and may shed new lights on the physiological importance of coenzyme A, a cofactor critical for the operation of various cellular metabolic processes.

Early posttraumatic seizures in pediatric traumatic brain injury: a multicenter analysis.

Objective: Early posttraumatic seizures (EPTSs) in children after traumatic brain injury (TBI) increase metabolic stress on the injured brain. The authors sought to study the demographic and radiographic predictors for EPTS, and to investigate the association between EPTS and death, and between EPTS and poor functional outcomes among children with moderate to severe TBI in Asia.

Methods: A secondary analysis of a retrospective TBI cohort among participating centers of the Pediatric Acute & Critical Care Medicine Asian Network was performed.

Associations of initial haemodynamic profiles and neurological outcomes in children with traumatic brain injury: a secondary analysis.

Introduction: Initial low systolic blood pressure (SBP) in paediatric traumatic brain injury (TBI) is associated with mortality. There is limited literature on how other haemodynamic parameters including heart rate (HR); diastolic blood pressure (DBP); mean arterial pressure (MAP); and shock index, paediatric age-adjusted (SIPA) affect not only mortality but also long-term neurological outcomes in paediatric TBI. We aimed to analyse the associations of these haemodynamic variables (HR, SBP, MAP, DBP and SIPA) with mortality and long-term neurological outcomes in isolated moderate-to-severe paediatric TBI.

White matter extension of the Melbourne Children's Regional Infant Brain atlas: M-CRIB-WM.

Brain atlases providing standardised identification of neonatal brain regions are key in investigating neurological disorders of early childhood. Our previously developed Melbourne Children's Regional Infant Brain (M-CRIB) and M-CRIB 2.0 neonatal brain atlases provide standardised parcellation of 100 brain regions including cortical, subcortical, and cerebellar regions.

Analysis of emergency department prediction tools in evaluating febrile young infants at risk for serious infections.

Objective: Febrile infants≤3 months old constitute a vulnerable group at risk of serious infections (SI). We aimed to (1) study the test performance of two clinical assessment tools-the National Institute for Health and Care Excellence (NICE) Traffic Light System and Severity Index Score (SIS) in predicting SI among all febrile young infants and (2) evaluate the performance of three low-risk criteria-the Rochester Criteria (RC), Philadelphia Criteria (PC) and Boston Criteria (BC) among well-looking febrile infants.

Methods: A retrospective validation study was conducted.

Hip fractures in young adults: a retrospective cross-sectional study of characteristics, injury mechanism, risk factors, complications and follow-up.

Unlabelled: This study characterises risk factors, complications and follow-up of minimal trauma hip fractures in young adults, adding to limited information examining the management framework. This group have severe systemic disease and significant risk of post-operative complications and subsequent fractures. Improved medical referral pathways enable management of osteoporosis and comorbid diseases.
