The Accuracy of Readily Available Consumer-Grade Oxygen Saturation Monitors in Pediatric Patients.

Background: Pulse oximetry measurement is ubiquitous in acute health care settings in high-income countries and is familiar to any parent whose child has been treated in such a setting. Oximeters for home use are readily available online and are incorporated in several smartphones and smartwatches.

Methods: We wished to determine how accurate are oximeters available online that are designated for adult and pediatric use, and the saturation monitor integrated in a smartphone, when used in children, compared to reference, hospital-grade oximeters.

Extensive crop-wild hybridization during Brassica evolution and selection during the domestication and diversification of Brassica crops.

Adaptive genetic diversity in crop wild relatives (CWRs) can be exploited to develop improved crops with higher yield and resilience if phylogenetic relationships between crops and their CWRs are resolved. This further allows accurate quantification of genome-wide introgression and determination of regions of the genome under selection. Using broad sampling of CWRs and whole genome sequencing, we further demonstrate the relationships among two economically valuable and morphologically diverse Brassica crop species, their CWRs, and their putative wild progenitors.

The methylome is altered for plants in a high CO world: Insights into the response of a wild plant population to multigenerational exposure to elevated atmospheric [CO ].

Unravelling plant responses to rising atmospheric CO concentration ([CO ]) has largely focussed on plastic functional attributes to single generation [CO ] exposure. Quantifying the consequences of long-term, decadal multigenerational exposure to elevated [CO ] and the genetic changes that may underpin evolutionary mechanisms with [CO ] as a driver remain largely unexplored. Here, we investigated both plastic and evolutionary plant responses to elevated [CO ] by applying multi-omic technologies using populations of Plantago lanceolata L.

Oral aspiration, type 1 laryngeal cleft, and respiratory tract infections in canadian inuit children.

Canadian Inuit infants suffer the highest rate of lower respiratory tract infections (LRTI's) in the world. The causes of this are incompletely understood. The primary objective of this study was to determine whether there exists an association between respiratory morbidity and oral aspiration in Inuit children.
