Article Synopsis
- The commentary proposes a framework for using SARS-CoV-2 antigen testing specifically for unexposed asymptomatic workers in selected workplaces.
- It draws on established safety and health principles, along with various research sources, to support its recommendations.
- The conclusion highlights that antigen testing is a valuable public health tool that can help reduce the spread of COVID-19 in workplaces when implemented thoughtfully as part of a broader prevention strategy.
Article Synopsis
- The paper discusses the essential background information that employers, workers, and health authorities need regarding pooled testing of employees.
- It emphasizes that pooled testing can be especially beneficial in areas with low COVID-19 prevalence by lowering testing numbers and costs.
- Effective pooled testing should be integrated into a wider workplace COVID-19 prevention strategy and can help prevent the spread of the virus among asymptomatic employees.
Examination of genetic variants involved in generation and biodisposition of kinins in patients with angioedema.
Allergy Asthma Clin Immunol
February 2015
Background: Angioedema (AE) is idiopathic in the majority of cases. We studied patients with AE for genetic variants of proteins involved with bradykinin generation and biodisposition.
Methods: One hundred sixty one patients with AE were recruited at a university hospital clinic.
There are approximately 1.2 million workers exposed to metalworking fluids (MWF), which are used to reduce the heat and friction associated with industrial machining and grinding operations. Irritancy and sensitization potential of 9 National Toxicology Program (NTP) nominated MWFs (TRIM 229, TRIM VX, TRIM SC210, CIMTECH 310, CIMPERIAL 1070, CIMSTAR 3800, SYNTILO 1023, SUPEREDGE 6768, and CLEAREDGE 6584) were examined in a combined local lymph node assay (LLNA).

The LLNA has also been used in research studies to evaluate contact allergen potency, as well as chemical structural-allergenic activity relationships. The 1-bromoalkanes have been used in such a manner as they represent a chemical series with generally the same chemical reactivity but differing in alkane carbon chain length-dependent lipid solubilities.

Influenza Other Respir Viruses
May 2007
Background: Influenza virus was used to characterize the efficacy of a cyclone-based, two-stage personal bioaerosol sampler for the collection and size fractionation of aerosolized viral particles.
Methods: A Collison single-jet nebulizer was used to aerosolize the attenuated FluMist vaccine into a calm-air settling chamber. Viral particles were captured with bioaerosol samplers that utilize 2 microcentrifuge tubes to collect airborne particulates.
