QM Investigation of Rare Earth Ion Interactions with First Hydration Shell Waters and Protein-Based Coordination Models.

Conventional methods for extracting rare earth metals (REMs) from mined mineral ores are inefficient, expensive, and environmentally damaging. Recent discovery of lanmodulin (LanM), a protein that coordinates REMs with high-affinity and selectivity over competing ions, provides inspiration for new REM refinement methods. Here, we used quantum mechanical (QM) methods to investigate trivalent lanthanide cation (Ln) interactions with coordination systems representing bulk solvent water and protein binding sites.

The Impact of Financial Coverage on Hearing Aid Utilization Rates Within the Military Health System.

Objectives: To investigate hearing aid utilization rates among populations with varying hearing aid insurance benefits.

Methods: A retrospective cohort study was performed. A total of 377 patients were included in the study after being identified through consecutive, hearing loss-related otology clinic visits.

Social vulnerability index associated with higher COVID-19 seroprevalence in Nigeria.

Social vulnerability has been shown to be a strong predictor of disparities in health outcomes. A common approach to estimating social vulnerability is using a composite index, such as the social vulnerability index (SVI), which combines multiple factors corresponding to key social determinants of health. Lawal and Osayomi created an SVI to explore key social determinants of health-related COVID-19 infection among the Nigerian population.
