Neutrophil Extracellular Traps and Bacterial Biofilms in Middle Ear Effusion of Children with Recurrent Acute Otitis Media

Bacteria persist within biofilms on the middle ear mucosa of children with recurrent and chronic otitis media however the mechanisms by which these...

High pneumococcal serotype specific IgG, IgG1 and IgG2 levels in serum and the middle ear of children with recurrent acute otitis media

Recurrent acute otitis media (AOM), frequently caused by Streptococcus pneumoniae, is a major paediatric health problem.

Australian Aboriginal Otitis-Prone Children Produce High-Quality Serum IgG to Putative Nontypeable Haemophilus influenzae Vaccine Antigens at Lower Titres Compared to Non-Aboriginal Children

Nontypeable Haemophilus influenzae (NTHi) is the most common bacterial otopathogen associated with otitis media (OM). NTHi persists in biofilms within the middle ears of children with chronic and recurrent OM. Australian Aboriginal children suffer exceptionally high rates of chronic and recurrent OM compared to non-Aboriginal children.

Haemophilus influenzae remains the predominant otitis media pathogen in Australian children undergoing ventilation tube insertion in the PCV13 era

Understanding patterns of bacterial carriage and otitis media (OM) microbiology is crucial for assessing vaccine impact and informing policy. The microbiology of OM can vary with geography, time, and interventions like pneumococcal conjugate vaccines (PCVs). We evaluated the microbiology of nasopharyngeal and middle ear effusions in children living in Western Australia, 11 years following the introduction of PCV13.

Elucidating the interaction of CF airway epithelial cells and rhinovirus: Using the host-pathogen relationship to identify future therapeutic strategies

A better understanding of the innate immune responses by CF airway epithelial cells is needed to identify why viral infections are more severe in CF

Pneumococcal conjugate vaccine primes mucosal immune responses to pneumococcal polysaccharide vaccine booster in Papua New Guinean children

Invasive pneumococcal disease remains a major cause of hospitalization and death in Papua New Guinean (PNG) children. We assessed mucosal IgA and IgG responses in PNG infants vaccinated with pneumococcal conjugate vaccine (PCV) followed by a pneumococcal polysaccharide vaccine (PPV) booster.

Safety, tolerability, and effect of a single aural dose of Dornase alfa at the time of ventilation tube surgery for otitis media: A Phase 1b double randomized control trial

One third of children require repeat ventilation tube insertion (VTI) for otitis media. Disease recurrence is associated with persistent middle ear bacterial biofilms. With demonstration that Dornase alfa (a DNase) disrupts middle ear effusion biofilms ex vivo, we identified potential for this as an anti-biofilm therapy to prevent repeat VTI. First, safety and tolerability needed to be measured.

Simplified bedside assessment of pulmonary gas exchange in very preterm infants at 36 weeks' postmenstrual age

We aimed to develop and validate a prediction table for a simplified measure of rightward shift of the fetal oxyhaemoglobin saturation (SpO2) versus inspired oxygen pressure (P IO2) curve as an objective marker of lung disease severity in very preterm infants, independent of unit altitude or oxygen prescribing policies.

Hospitalisation for bronchiolitis in infants is more common after elective caesarean delivery

The authors previously reported an increased risk of hospitalisation for acute lower respiratory infection up to age 2 years in children delivered by...

Pneumococcal conjugate vaccination at birth in a high-risk setting: No evidence for neonatal T-cell tolerance

Concerns about the risk of inducing immune deviation-associated "neonatal tolerance" as described in mice have restricted the widespread adoption...
