Bicaval dual lumen cannula placement using transthoracic echocardiography in COVID-19 scenario: pearls and pitfalls.

A woman in her 50s who had been diagnosed with COVID-19 developed deep vein thrombosis in the left femoral vein extending into inferior vena cava (IVC). An IVC filter was placed to prevent fatal pulmonary embolism. Her respiratory failure subsequently deteriorated despite optimal mechanical ventilation and required venovenous extracorporeal membrane oxygenation (VV-ECMO) as a rescue therapy.

Genotype-phenotype correlations in SCN8A-related disorders reveal prognostic and therapeutic implications.

We report detailed functional analyses and genotype-phenotype correlations in 392 individuals carrying disease-causing variants in SCN8A, encoding the voltage-gated Na+ channel Nav1.6, with the aim of describing clinical phenotypes related to functional effects. Six different clinical subgroups were identified: Group 1, benign familial infantile epilepsy (n = 15, normal cognition, treatable seizures); Group 2, intermediate epilepsy (n = 33, mild intellectual disability, partially pharmaco-responsive); Group 3, developmental and epileptic encephalopathy (n = 177, severe intellectual disability, majority pharmaco-resistant); Group 4, generalized epilepsy (n = 20, mild to moderate intellectual disability, frequently with absence seizures); Group 5, unclassifiable epilepsy (n = 127); and Group 6, neurodevelopmental disorder without epilepsy (n = 20, mild to moderate intellectual disability).

Levetiracetam Versus Phenobarbital for Neonatal Seizures: A Randomized Controlled Trial.

Background And Objectives: There are no US Food and Drug Administration-approved therapies for neonatal seizures. Phenobarbital and phenytoin frequently fail to control seizures. There are concerns about the safety of seizure medications in the developing brain.

Highly Conducting and Highly Transparent Oxide/Metal/Oxide Structures for Ultraviolet-C Light Sources Utilizing a Thin Cu Wetting Interlayer.

The ZnMgBeO/Cu/Ag/ZnMgBeO multilayer structures were designed, sputter-deposited at room temperature, and characterized in detail. Results indicated that the multilayer structures with high transmission (higher than 90% at the visual wavelength range) can be readily obtained by simply inserting a thin (∼5 nm) Cu wetting layer, which renders the thin Ag layers (∼5 nm thick) continuous and smooth. It was also observed that the optical absorption edges of the multilayer structures increase as the energy band-gaps of the top/bottom oxide layers increase and the multilayer structures with the energy band gap of ∼6.
