Multicenter StudyHigher mortality rates among the elderly with mild traumatic brain injury: a nationwide cohort study.
It is known that the risk of death in elderly patients with moderate to severe traumatic brain injury is increased. However, the relationship between mild traumatic brain injury and death has never been established. We investigated the mortality rates of older patients with mild traumatic brain injury in Taiwan to evaluate if there is a higher risk of death compared with the general population. ⋯ Mild traumatic brain injury is an independent significant risk factor for death in the elderly.

Multicenter Study
Spirometric reference values for healthy nonsmoking Saudi adults.
To derive prediction equations of spirometric values of healthy Saudi adults and to compare the derived equations with equations reported in selected population. ⋯ The reference spirometric values derived in our study were significantly lower than the predicted values derived by the American equations.

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 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.
