Association of licensure and relationship requirement waivers with out-of-state tele-mental health care, 2019-2021.

During the COVID-19 public health emergency, states waived in-state licensure and pre-existing patient-physician relationship requirements to increase access to care. We exploit this state telehealth policy variation to estimate the association of in-state licensure requirement waivers and pre-existing patient-physician relationship requirement waivers with out-of-state tele-mental health care utilization of patients diagnosed with COVID-19. Using claims from January 2019 until December 2021 of 2 037 977 commercially insured individuals in 3 metropolitan statistical areas (MSAs) straddling Midwestern state borders, we found increased out-of-state telehealth utilization as a share of out-of-state mental health care by 0.

Intracellular iron accumulation facilitates mycobacterial infection in old mouse macrophages.

Aging has a significant impact on the immune system, leading to a gradual decline in immune function and changes in the body's ability to respond to bacterial infections. Non-tuberculous mycobacteria (NTM), also known as atypical mycobacteria or environmental mycobacteria, are commonly found in soil, water, and various environmental sources. While many NTM species are considered opportunistic pathogens, some can cause significant infections, particularly in individuals with compromised immune systems, such as older individuals.

Long-haul COVID: healthcare utilization and medical expenditures 6 months post-diagnosis.

Background: Despite extensive evidence that COVID-19 symptoms may persist for up to a year, their long-term implications for healthcare utilization and costs 6 months post-diagnosis remain relatively unexplored. We examine patient-level association of COVID-19 diagnosis association of COVID-19 diagnosis with average monthly healthcare utilization and medical expenditures for up to 6 months, explore heterogeneity across age groups and determine for how many months post-diagnosis healthcare utilization and costs of COVID-19 patients persist above pre-diagnosis levels.

Methods: This population-based retrospective cohort study followed COVID-19 patients' healthcare utilization and costs from January 2019 through March 2021 using claims data provided by the COVID-19 Research Database.
