Most studies of the rapid response team (RRT) investigate the effect of introducing an RRT on outcomes of all hospitalised patients. Less information exists on RRT patient epidemiology, or changes in RRT call numbers with time. ⋯ Annual RRT calls are increasing in many Australian hospitals, and now affect more than 14 700 patients annually. Inhospital mortality of RRT patients is about 25%, and about 20% of patients who die in hospital are reviewed by the RRT. Further research is needed to understand the reason for the high inhospital mortality of RRT patients.

Multicenter Study Observational Study
Oxygen therapy in non-intubated adult intensive care patients: a point prevalence study.
Oxygen is commonly administered to intensive care unit patients. Although there is knowledge of how oxygen is administered to mechanically ventilated patients, there are few data about its use in non-intubated ICU patients. ⋯ Oxygen therapy is commonly administered to non-intubated adult patients in New Zealand and Australian ICUs. Most patients received oxygen by simple nasal cannulae, and oxygen therapy prescriptions were often absent or incomplete. We advise continuing education to ensure that oxygen is prescribed, administered and documented correctly.

Multicenter Study
Effects of ivacaftor on severely ill patients with cystic fibrosis carrying a G551D mutation.
Recently, ivacaftor, a CFTR-potentiator, has been shown to be effective and safe in patients with cystic fibrosis carrying a G551D mutation and moderately impaired lung function. The objective of this retrospective study was to assess efficacy and safety of ivacaftor in severely ill patients with at least one G551D mutation. ⋯ Ivacaftor was effective in many patients with poor lung function. The response was, however, variable. Although the drug appeared safe for most of these patients, increased bronchial secretions may warrant intensified physiotherapy and intravenous antibiotic treatment when ivacaftor is initiated.

Multicenter Study Comparative Study
Discriminative analysis of early-stage Alzheimer's disease and normal aging with automatic segmentation technique in subcortical gray matter structures: a multicenter in vivo MRI volumetric and DTI study.
Previous studies have revealed that amyloid depositions exist in not only the hippocampus but in other subcortical gray matter structures as well. Diffusion-tensor imaging (DTI) parameters might be more sensitive measures of early degeneration in Alzheimer's disease (AD) than conventional magnetic resonance imaging (MRI) techniques. ⋯ Pathological changes takes place in the hippocampus and other subcortical gray matter structures in early-stage AD. Diffusive imaging has great diagnostic significance in early-stage AD. The combination of both imaging modalities can lead to better discrimination between early-stage AD and normal aging.

Randomized Controlled Trial Multicenter Study Comparative Study
Comparison of two methods for acquisition of sputum samples for diagnosis of suspected tuberculosis in smear-negative or sputum-scarce people: a randomised controlled trial.
Sputum obtained either under instruction from a health-care worker or through induction can improve case detection of active tuberculosis. However, the best initial sputum sampling strategy for adults with suspected smear-negative or sputum-scarce tuberculosis in primary care is unclear. We compared these two methods of sample acquisition in such patients. ⋯ South African National Research Foundation, European Commission, National Institutes of Health, European and Developing Countries Clinical Trials Partnership, Discovery Foundation.
