Introduction: Hepatitis B vaccination was nationally funded for adolescents in 1996, with inclusion of universal infant immunisation under the National Immunisation Program (NIP) in May 2000. This study describes hepatitis B epidemiology in Australia in the two decades since 2000.
Methods: This article analyses newly-acquired (within the prior 24 months) and unspecified (all other) hepatitis B notifications (2000-2019) from the National Notifiable Diseases Surveillance System; acute hepatitis B hospitalisations (2001-2019) from the National Hospital Morbidity Database; and acute (2000-2019) and chronic (2006-2019) hepatitis B deaths from the Australian Bureau of Statistics and Australian Coordinating Registry.
Background: Pulmonary exacerbations frequently lead to an irrevocable loss of lung function in cystic fibrosis (CF) patients. Although extended antibiotic duration has not been shown to be associated with improved outcomes in CF overall, it is not known whether there is a subset of patients who may benefit from longer treatment courses.
Methods: This was a retrospective cohort study, using the Toronto CF Database from 1997 to 2012, of CF individuals with pulmonary exacerbations requiring intravenous antibiotic treatment.
Pulmonary exacerbations are important clinical events for cystic fibrosis (CF) patients. Studies assessing the ability of the lung clearance index (LCI) to detect treatment response for pulmonary exacerbations have yielded heterogeneous results. Here, we conduct a retrospective analysis of pooled LCI data to assess treatment with intravenous antibiotics for pulmonary exacerbations and to understand factors explaining the heterogeneous response.

The objective of this study was to identify factors associated with lung function response to antibiotic treatment of pulmonary exacerbations.
Methods: As a secondary analysis of a randomized, controlled trial of intravenous antibiotic treatment for pulmonary exacerbations in CF patients, we investigated whether baseline factors and changes in sputum bacterial density, serum or sputum inflammatory markers were associated with recovery of lung function and risk of subsequent exacerbation.
