Low-cost Fabrication of Tunable Band Gap Composite Indium and Gallium Nitrides.

III-nitride materials have been linked with a vast number of exciting applications from power electronics to solar cells. Herein, polycrystalline InN, GaN and systematically controlled InGaN composite thin films are fabricated on FTO glass by a facile, low-cost and scalable aerosol assisted chemical vapor deposition technique. Variation of the indium content in the composite films leads to a dramatic shift in the optical absorbance properties, which correlates with the band edges shifting between those of GaN to InN.

Improving pediatric resident laryngoscopy training through the use of a video laryngoscope.

Importance: Opportunities for pediatric residents to perform direct laryngoscopy and tracheal intubation (DLTI) are few and the success rate is low.

Objective: We hypothesize that incorporation of video laryngoscope (McGrath MAC) into pediatric residents DLTI simulation course will improve the simulated DLTI success rate.

Methods: Residents were given 3 attempts at DLTI: (1) baseline using a conventional laryngoscope (CL); (2) using a video laryngoscope (VL); and (3) again using the CL.

Hospital-Acquired Hyponatremia in Children Following Hypotonic versus Isotonic Intravenous Fluids Infusion.

Hypotonic solutions have been used in pediatrics for maintenance of intravenous (IV) hydration. However, recent randomized control trials and cohort studies have raised significant concerns for association with hospital-acquired hyponatremia (HAH). The study aimed to assess whether the use of hypotonic parenteral solutions (PS) compared with isotonic PS is associated with increased HAH risk in children with common pediatric conditions.

Six-Digit CPK and Mildly Affected Renal Function in McArdle Disease.

A previously healthy, white 12-year-old girl presented with diffuse body aches and poor perfusion. She developed severe respiratory failure and marked rhabdomyolysis and was mechanically ventilated. Although her CPK peaked at 500,000 IU/L, her renal function was mildly affected and her creatinine did not exceed the 0.

Ability of code leaders to recall CPR quality errors during the resuscitation of older children and adolescents.

Aim: Performance of high quality CPR is associated with improved resuscitation outcomes. This study investigates code leader ability to recall CPR error during post-event interviews when CPR recording/audiovisual feedback-enabled defibrillators are deployed.

Patients And Methods: Physician code leaders were interviewed within 24h of 44 in-hospital pediatric cardiac arrests to assess their ability to recall if CPR error occurred during the event.

Bi-caval dual lumen venovenous extracorporeal membrane oxygenation and high-frequency percussive ventilatory support for postintubation tracheal injury and acute respiratory distress syndrome.

Bi-caval dual lumen venovenous extracorporeal membrane oxygenation (VV-ECMO) as a nonoperative approach to postintubation tracheal injury has not been described. We report the case of a 7-year-old boy who sustained a postintubation tracheal injury, developed acute respiratory distress syndrome from aspiration and viral pneumonitis, and was supported on bi-caval dual lumen VV-ECMO for 16 days until the trachea healed without surgical repair. Before ECMO decannulation, high-frequency percussive ventilation using a volumetric diffusive respiration ventilator was used for lung recruitment and airway clearance without disruption of the healed trachea.

The first quantitative report of ventilation rate during in-hospital resuscitation of older children and adolescents.

Aim: During adult cardiac arrest, rescuers frequently provide ventilations at rates exceeding those recommended by the American Heart Association (AHA). Excessive ventilation is associated with worse clinical outcome after adult cardiac arrest. This study is the first to characterize ventilation rate adherence to AHA guidelines during in-hospital pediatric cardiac arrest resuscitation.
