PCV10 elicits Protein D IgG responses in Papua New Guinean children but has no impact on NTHi carriage in the first two years of life

Nasopharyngeal colonisation with nontypeable Haemophilus influenzae (NTHi) is associated with development of infections including pneumonia and otitis media. The 10-valent pneumococcal conjugate vaccine (PCV10) uses NTHi Protein D (PD) as a carrier. Papua New Guinean children have exceptionally early and dense NTHi carriage, and high rates of NTHi-associated disease.

Pneumococcal responses are similar in Papua New Guinean children aged 3-5 years vaccinated in infancy with pneumococcal polysaccharide vaccine with or without prior pneumococcal conjugate vaccine, or without pneumococcal vaccination

We studied in a non-randomized follow-up trial the persistence of pneumococcal immunity in children, 3-5 years of age, in community controls of a similar age.

Cochrane Corner: interventions to improve hearing aid use in adult auditory rehabilitation

This "Cochrane Corner" will be a recurring feature in the journal that highlights systematic reviews relevant to audiology, with invited commentary to aid clinical decision making.

Mental health problems among 4–17-year-olds with hearing problems: results from a nationally representative study

Clinicians caring for children and young people with hearing problems should be alert for heightened risk of specific mental health problems based on age and the nature of hearing problems.

Production of IgG antibodies to pneumococcal polysaccharides is associated with expansion of ICOS+ circulating memory T follicular-helper cells which is impaired by HIV infection

Dysfunction of T follicular-helper cells is a possible cause of impaired germinal centre and IgG antibody responses in individuals with HIV

Cord blood Streptococcus pneumoniae-specific cellular immune responses predict early pneumococcal carriage in high-risk infants in Papua New Guinea

We aimed to explore whether newborns in high-risk areas have pre-existing pneumococcal-specific cellular immune responses that effects early acquisition.

Otitis-prone children produce functional antibodies to pneumolysin and pneumococcal polysaccharides

The production of functional antipneumococcal antibodies in otitisprone children demonstrates that they respond to the current pneumococcal conjugate vaccine (PCV)and are likely to respond to pneumolysin-based vaccines as effectively as healthy children.
