ABSTRACT
Radiocarbon dating of the earliest occupational phases at the Cooper's Ferry site in western Idaho indicates that people repeatedly occupied the Columbia River basin, starting between 16,560 and 15,280 calibrated years before the present (cal yr B.P.). Artifacts from these early occupations indicate the use of unfluted stemmed projectile point technologies before the appearance of the Clovis Paleoindian tradition and support early cultural connections with northeastern Asian Upper Paleolithic archaeological traditions. The Cooper's Ferry site was initially occupied during a time that predates the opening of an ice-free corridor (≤14,800 cal yr B.P.), which supports the hypothesis that initial human migration into the Americas occurred via a Pacific coastal route.

Bronchiolitis is an acute inflammatory disease of the lower small airways predominantly occurring in infants younger than 1 year of age. As a result of the respiratory distress associated with bronchiolitis, infants frequently require admission to an intensive care unit for respiratory support. Thirty-five infants diagnosed with bronchiolitis were admitted to a combined adult/paediatric tertiary intensive care unit over a 2-year period for nasal bubble continuous positive airway pressure (CPAP). Following this therapy, 20 (57.14%) of these infants could be transferred to the medical ward of the onsite paediatric hospital. The remainder required transfer to the national paediatric intensive care unit (PICU) for ongoing observation and/or positive pressure ventilation. Nasal bubble CPAP is a simple therapy that can be easily set up at the bedside. The use of nasal bubble CPAP enabled infants to remain in their geographical area, thus improving family visiting access and reducing the demand for paediatric beds in the national PICU.
