Elevated neurofilament light chain associated with cobalt/chromium metal neurotoxicity in a patient with a failed hip implant.

Background: It is known that the heavy metals cobalt and chromium are associated with neurotoxicity. Chromium (Cr) and Cobalt (Co) are both components of metal-on-metal (MoM) implants which can be degraded/fragmented and released into the bloodstream. Neurofilament Light Chain (NfL) is a neuron-specific protein that increases in serum following axonal damage.

Iron and Copper Liver Concentrations in Wilson Disease.

Background And Aims: Wilson disease (WD) results in the defective incorporation of copper into ceruloplasmin as well as decreased biliary copper excretion. Secondary iron overload has also been associated with WD; however, the prevalence is currently unknown. This study aims to determine the prevalence of potential secondary iron overload in patients suspected to have WD.

Dysfunctional copper homeostasis in affects genomic and neuronal stability.

While copper (Cu) is an essential trace element for biological systems due to its redox properties, excess levels may lead to adverse effects partly due to overproduction of reactive species. Thus, a tightly regulated Cu homeostasis is crucial for health. Cu dyshomeostasis and elevated labile Cu levels are associated with oxidative stress and neurodegenerative disorders, but the underlying mechanisms have yet to be fully characterized.

AI-Augmented Kidney Stone Composition Analysis with Auto-Release Improves Quality, Efficiency, Cost-Effectiveness, and Staff Satisfaction.

Background: We sought to evaluate key performance indicators related to an internally developed and deployed artificial intelligence (AI)-augmented kidney stone composition test system for potential improvements in test quality, efficiency, cost-effectiveness, and staff satisfaction.

Methods: We compared quality, efficiency, staff satisfaction, and financial data from the 6 months after the AI-augmented laboratory test system was deployed (test period) with data from the same 6-month period in the previous year (control period) to determine if AI-augmentation improved key performance indicators of this laboratory test.

Results: In the 6 months following the deployment (test period) of the AI-augmented kidney stone composition test system, 44 830 kidney stones were analyzed.

Cellular mechanisms of copper neurotoxicity in human, differentiated neurons.

Copper (Cu) is an essential trace element involved in fundamental physiological processes in the human body. Even slight disturbances in the physiological Cu homeostasis are associated with the manifestation of neurodegenerative diseases. While suggesting a crucial role of Cu in the pathogenesis, the exact mechanisms of Cu neurotoxicity involved in the onset and progression of neurological diseases are far from understood.
