High-Performance Nickel-Bismuth Oxide Electrocatalysts Applicable to Both the HER and OER in Alkaline Water Electrolysis.

As an electrocatalyst for water electrolysis, nickel oxide (NiO) has received significant attention due to its cost-effectiveness and high reactivity among non-noble-metal-based catalytic materials. However, NiO still exhibits poor alkaline hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) kinetics compared to conventional noble metal-based catalysts. This is because NiO has a strong interaction with protons for the HER and too low free energy of the OH* state, resulting in slower rate-determining step (RDS) kinetics for the OER.

An Intrathecal Pump Misadventure in Two Acts: An Unrecognized Partial Pocket Fill Followed by an Unusual Withdrawal Syndrome Two Months Later.

We present a case of a patient with an intrathecal pump who experienced an unrecognized partial pocket fill, leading to an atypical opioid withdrawal characterized by akathisia. A 57-year-old female with multiple myeloma presented to an emergency department with new-onset akathisia requiring admission. Eight weeks prior, her intrathecal pump was refilled with morphine, bupivacaine, and ziconotide.

Real-world clinical impact of plasma cell-free DNA metagenomic next-generation sequencing assay.

Objective: To describe the real-world clinical impact of a commercially available plasma cell-free DNA metagenomic next-generation sequencing assay, the Karius test (KT).

Methods: We retrospectively evaluated the clinical impact of KT by clinical panel adjudication. Descriptive statistics were used to study associations of diagnostic indications, host characteristics, and KT-generated microbiologic patterns with the clinical impact of KT.

Neurodevelopmental Follow-Up in Children with Intrauterine and Perinatal Exposure to Chikungunya Virus.

Objective: To investigate the effects of intrauterine and perinatal exposure to chikungunya virus (CHIKV) on neurodevelopment in infants and toddlers.

Study Design: We conducted a cohort study comparing children with intrauterine or perinatal exposure to maternal CHIKV infection with unexposed controls in Rio de Janeiro, Brazil. Neurodevelopment was assessed with General Movement Assessments in the first 6 months of life, and the Bayley-III Scales of Infant and Toddler Development and Modified Checklist for Autism in Toddlers for older children.
