Wernicke encephalopathy is a well-described neurological complication of thiamine deficiency that is classically characterized by a triad of mental confusion, ophthalmoplegia, and gait ataxia. Although most commonly linked to alcoholism and thiamine deficiency in adults, it can present in pediatric patients. Wernicke encephalopathy presenting as dysnatremias is not well described.

Background And Objectives: The challenge of identifying preterm infants with bronchopulmonary dysplasia (BPD) that need tracheostomy placement may delay goals of care (GOC) discussions. By identifying infants with a low probability of ventilation liberation, timely GOC discussions may reduce the time to tracheostomy. Our SMART aim was to reduce the postmenstrual age (PMA) of GOC discussions by 20% in infants with BPD and prolonged invasive ventilatory requirement by October 2020.

Pediatric advanced life support (PALS) training is critical for pediatric residents. It is unclear how well PALS skills are developed during this course or maintained overtime. This study evaluated PALS skills of pediatric interns using a validated PALS performance score following their initial PALS certification.

Surface enhanced Raman spectra (SERS) of normal red blood cells (RBCs) and Plasmodium falciparum infected RBCs (iRBCs) at different post invasion time were obtained based on silver nanorod array substrates. Distinct spectral differences were observed due to the cell membrane modification of RBCs during malaria infection. The SERS spectra of ring stage iRBCs had a characteristic Raman peak at Δv=1599cm(-1) as compared to those of normal RBCs, while the trophozoite and schizoid stages had identical SERS spectra with a characteristic peak at Δv=723cm(-1), which is significantly different from ring stage iRBCs, consistent with ongoing modification of the iRBC membrane.
