Socioeconomically Disadvantaged Groups May Have Underused The Emergency Department For Nonavoidable Visits, 2018-22.

In the decades preceding the COVID-19 pandemic, emergency department (ED) use increased more rapidly for socioeconomically disadvantaged patients than for advantaged patients, often because of barriers to accessing office-based care. However, it remains unknown whether the pandemic has had durable effects on socioeconomic disparities in ED use. We conducted a retrospective cohort study of ED visits in the US, using multipayer claims data.

Demographic Variation In US Outpatient Hydroxychloroquine And Ivermectin Use During The COVID-19 Pandemic.

As COVID-19 surged across the US starting in 2020, so too did the use of repurposed medications such as hydroxychloroquine and ivermectin to treat COVID-19 infections. Use of these medications throughout the public health emergency and across demographic subgroups is not well understood. Using insurance claims from the MedInsight Emerging Experience Research Database for 8.

Trends in US Ambulatory Care Patterns During the COVID-19 Pandemic, 2019-2021.

Importance: Following reductions in US ambulatory care early in the pandemic, it remains unclear whether care consistently returned to expected rates across insurance types and services.

Objective: To assess whether patients with Medicaid or Medicare-Medicaid dual eligibility had significantly lower than expected return to use of ambulatory care rates than patients with commercial, Medicare Advantage, or Medicare fee-for-service insurance.

Design, Setting, And Participants: In this retrospective cohort study examining ambulatory care service patterns from January 1, 2019, through February 28, 2021, claims data from multiple US payers were combined using the Milliman MedInsight research database.

Embryonic stem cell-derived motor neurons preserve muscle after peripheral nerve injury.

Background: The potential of motor neuron progenitor cell transplants to preserve muscle tissue after denervation was studied in in vivo and in vitro adult mammalian model of peripheral nerve injury.

Methods: Embryonic stem cells were differentiated to induce cholinergic motor neuron progenitors. Flourescent-labeled progenitor cells were injected into the gastrocnemius muscle of Sprague-Dawley rats (n = 10) after denervation by ipilateral sciatic nerve transection.
