Tolerability and Safety of Lacosamide in Neonatal Population.

Lacosamide is a newer antiepileptic medication used in refractory neonatal seizures with limited safety and efficacy data. This case series spans 4 years and includes 38 neonates cared for in the neonatal, pediatric, and cardiovascular intensive care units, who received lacosamide for refractory seizures. Because lacosamide affects atrioventricular node function in adults, among other metrics, electrocardiogram (ECG) changes were monitored closely in these neonates.

Neonatal Electroencephalogram Electrode-Related Pressure Injury Prevention Quality Improvement Study.

Objective: To lengthen the days between electroencephalogram electrode-related pressure injury (EERPI) to 100 EERPI-free days in 6 months of study implementation with a goal to maintain 200 EERPI-free days thereafter (≤1 EERPI event/year).

Methods: This quality improvement study took place in a level IV neonatal ICU over three epochs spanning 2 years: epoch 1 or baseline (January-June 2019), epoch 2 or implementation of intervention (July-December 2019), and epoch 3 or sustainment (January-December 2020). A daily electroencephalogram (EEG) skin assessment tool, introduction in practice of a flexible hydrogel EEG electrode, and successive rapid-cycle staff-education sessions were key interventions of the study.

Fetal Cerebral Sinovenous Thrombosis and Dural Sinus Malformation.

Background: Fetal cerebral sinovenous thrombosis (CSVT) and dural sinus malformation (DSM) are rare types of fetal cerebral venous pathology that are becoming increasingly recognized as fetal imaging advances. Fetal DSMs are a common source of fetal CSVT, although CSVT may occur without a DSM. The literature on these disorders is limited.

Spectral Imaging for Microbubble Characterization.

Microbubbles stabilized by an outer lipid shell have been studied extensively for both diagnostic and therapeutic applications. The shell composition can significantly influence microbubble behavior, but performing quantitative measurements of shell properties is challenging. The aim of this study is to investigate the use of spectral imaging to characterize the surface properties of a range of microbubble formulations representing both commercial and research agents.

Temporal changes in the distribution of thoracic duct lymphoblasts to synovium and other tissues of rats with adjuvant-induced arthritis.

The distribution of lymphoblasts(lymphocytes in cell cycle) obtained from the central lymph of donor rats and transferred adoptively to syngeneic recipients has been shown previously to be influenced by the presence of arthritis in either donor or recipient rats. The intent of the present study was to examine patterns of distribution of lymphoblasts in the early period after transfer, when extravasation of donor lymphoblasts was expected to occur. Thoracic duct lymphoblasts labelled in vitro with [125I]-iododeoxyuridine were detected in recipient rats by external radiometry and autoradiography.
