Context: Studies comparing initial therapy for multisystem inflammatory syndrome in children (MIS-C) provided conflicting results.

Objective: To compare outcomes in MIS-C patients treated with intravenous immunoglobulin (IVIG), glucocorticoids, or the combination thereof.

Data Sources: Medline, Embase, CENTRAL and WOS, from January 2020 to February 2022.

Background: Test-negative design (TND) studies have produced validated estimates of vaccine effectiveness (VE) for influenza vaccine studies. However, syndrome-negative controls have been proposed for differentiating bias and true estimates in VE evaluations for COVID-19. To understand the use of alternative control groups, we compared characteristics and VE estimates of syndrome-negative and test-negative VE controls.

Article Synopsis
  • Two cohort studies on multisystem inflammatory syndrome in children (MIS-C) showed conflicting results on the effectiveness of initial treatment with IVIG alone versus IVIG plus glucocorticoids.
  • * The study compared patients defined by the CDC and WHO definitions of MIS-C, revealing that about 9.5% of the OC-19 patients didn't meet the WHO criteria, while 10.3% of BATS patients didn't meet the CDC criteria.
  • * The findings suggested that greater illness severity and cardiovascular issues in the OC-19 cohort, rather than different case definitions, might explain the varying conclusions on the best initial treatment for MIS-C, highlighting the need for severity considerations in future research.

Ambient fine particulate matter less than 2.5 μm in aerodynamic diameter (PM) has been linked to various adverse health outcomes. PM arises from both natural and anthropogenic sources, and PM concentrations can vary over space and time.

The western United States has experienced increasing wildfire activities, which have negative effects on human health. Epidemiological studies on fine particulate matter (PM) from wildfires are limited by the lack of accurate high-resolution PM exposure data over fire days. Satellite-based aerosol optical depth (AOD) data can provide additional information in ground PM concentrations and has been widely used in previous studies.

Exposure to fine particulate matter (PM) has been associated with a wide range of negative health outcomes. The overwhelming majority of the epidemiological studies that helped establish such associations was conducted in regions with sufficient ground observations and other supporting data, i.e.
