Antecedent and persistent symptoms in COVID-19 and other respiratory illnesses: Insights from prospectively collected data in the BRACE trial

Some individuals have a persistence of symptoms following both COVID-19 (post-acute COVID-19 syndrome; PACS) and other viral infections. This study used prospectively collected data from an international trial to compare symptoms following COVID-19 and non-COVID-19 respiratory illness, to identify factors associated with the risk of PACS, and to explore symptom patterns before and after COVID-19 and non-COVID-19 respiratory illnesses.

Same-visit hepatitis C testing and treatment to accelerate cure among people who inject drugs (the QuickStart Study): A cluster randomised cross-over trial protocol

Despite universal access to government-funded direct-acting antivirals in 2016, the rate of hepatitis C treatment uptake in Australia has declined substantially. Most hepatitis C is related to injecting drug use; reducing the hepatitis C burden among people who inject drugs is, therefore, paramount to reach hepatitis C elimination targets.

Serological Responses to Streptococcus pyogenes Vaccine Candidate Antigens Suggests That Streptococcus dysgalactiae Is the Predominant Cause of Lower Limb Cellulitis

A future Streptococcus pyogenes (Strep A) vaccine will ideally prevent a significant burden of lower limb cellulitis; however, natural immune responses to proposed vaccine antigens following an episode of cellulitis remain uncharacterized.

Immunogenicity, reactogenicity, and IgE-mediated immune responses of a mixed whole-cell and acellular pertussis vaccine schedule in Australian infants: A randomised, double-blind, noninferiority trial

In many countries, infant vaccination with acellular pertussis (aP) vaccines has replaced use of more reactogenic whole-cell pertussis (wP) vaccines. Based on immunological and epidemiological evidence, we hypothesised that substituting the first aP dose in the routine vaccination schedule with wP vaccine might protect against IgE-mediated food allergy. We aimed to compare reactogenicity, immunogenicity, and IgE-mediated responses of a mixed wP/aP primary schedule versus the standard aP-only schedule.

Functional skills in MECP2 duplication syndrome: developmental dynamics and regression

MECP2 duplication syndrome (MDS) is an ultrarare, X-linked neurodevelopmental disorder that is poorly understood in terms of its natural history and phenotypic variability. There is limited information on how individuals with MDS acquire, retain or lose fundamental functional skills (gross motor, purposeful hand function and communication) - that of which this study aimed to better characterise in the largest case series to date.

Neonatal and infant mortality after maternal influenza and pertussis vaccination: Probabilistically linked cohort study

Maternal influenza and pertussis vaccination is an important strategy to reduce morbidity and mortality in infants. Previous vaccine safety studies have mostly focused on the association between maternal vaccination and fetal death.

Understanding motivation and experience in participating in a paediatric SARS-CoV-2 serosurvey, in Australia

Serosurveys are considered as a valuable tool in estimating population immunity and infection rates but recruitment of children to provide paediatric estimates can be challenging. A novel approach of sampling children undergoing anaesthesia was utilised for a SARS-CoV-2 serosurvey in Australian children and we explore the reasons for participation, feedback on the approach and importance of research into Coronavirus Diseases 2019 (COVID-19).

Longitudinal surveillance of group A streptococcal pharyngitis and impetigo in remote Western Australian school children informs acute rheumatic fever prevention

The prevalence of impetigo and pharyngitis - which are both superficial group A streptococcus (GAS) infections that precede acute rheumatic fever - is poorly defined. Guidelines recommend the early diagnosis of both infections to prevent ARF; however, screening to enable the concurrent detection of these infections in high-risk populations has rarely been performed.

Convalescent plasma in hospitalised patients with COVID-19

Convalscent plasma (CP) was identified as a potential therapy for COVID-19 available early in the pandemic.

Invasive mould infection in children – advances made or obstacles remaining?

Invasive mould infection (IMI) is a major cause of morbidity and mortality in immunocompromised children. Outcomes for paediatric patients with IMI remain poor, due in part to the limitations of available diagnostic tools and therapeutic agents.
