See one, see one, teach one - Decisions on allocating intubation opportunities in pediatric emergency medicine.

Background: Decisions about who should perform tracheal intubation in academic settings must balance the needs of trainees to develop competency in pediatric intubation with patient safety. Airway protocols during the COVID-19 pandemic may have reduced opportunities for trainees, representing an opportunity to examine the impact of shifting laryngoscopy responsibilities away from trainees.

Methods: This observational study combined data from 11 pediatric emergency departments in North America participating in either the National Emergency Airway Registry for Children (NEAR4KIDS) or a national pediatric emergency medicine airway education collaborative.

Longitudinal Survey of Microbiota in Hospitalized Preterm Very-Low-Birth-Weight Infants.

Objectives: The aim of the present study was to examine the changes in bacteria in hospitalized preterm infants during the first month of life.

Methods: Rectal swabs were collected daily from 12 preterm infants. DNA was extracted from swabs from day of birth and weekly thereafter.

Conductive hydrogels with tailored bioactivity for implantable electrode coatings.

The development of high-resolution neuroprosthetics has driven the need for better electrode materials. Approaches to achieve both electrical and mechanical improvements have included the development of hydrogel and conducting polymer composites. However, these composites have limited biological interaction, as they are often composed of synthetic polymers or non-ideal biological polymers, which lack the required elements for biorecognition.

Efficacy of fluconazole prophylaxis for prevention of invasive fungal infection in extremely low birth weight infants.

Background: Invasive fungal infections (IFI) are an important cause of late-onset disease in extremely low birth weight (ELBW) infants. Despite prior trials of fluconazole prophylaxis in neonates, application of this regimen remains controversial. Review of our neonatal intensive care unit aggregate annual number of fungal isolates from sterile sites in ELBW infants from 1997 to 2006 suggested a significant decrease following the institution of routine prophylactic fluconazole in February 2002.

Adsorption kinetics of p-nitrobenzenethiol self-assembled monolayers on a gold surface.

The adsorption kinetics of octadecanethiol (ODT) and p-nitrobenzenethiol (NBT) from ethanol solutions has been studied by means of contact angle, optical ellipsometry, angle-resolved X-ray photoelectron spectroscopy (ARXPS), and grazing angle attenuated total reflection Fourier transform infrared (FTIR) measurements. ODT data were used as a reference for the kinetics studies of film growth. The growth of self-assembled monolayers from dilute solutions follows Langmuir isotherm adsorption kinetics.

Room-Temperature, Electric Field-Induced Creation of Stable Devices in CulnSe2 Crystals.

Multiple-junction structures were formed, on a microscopic scale, at room temperature, by the application of a strong electric field across originally homogeneous crystals of the ternary chalcopyrite semiconductor CulnSe(2). After removal of the electric field, the structures were examined with electron beam-induced current microscopy and their current-voltage characteristics were measured. Bipolar transistor action was observed, indicating that sharp bulk junctions can form in this way at low ambient temperatures.
