Food allergy is associated with lower risk of SARS-CoV-2 infection
NIH study finds high BMI and obesity raise infection risk, but asthma does not. A National Institutes of Health-funded study has found that people with food allergies are less likely...

Allergological study in patients vaccinated against COVID-19 with suspected allergic reactions - Allergy, Asthma & Clinical Immunology
Source : https://aacijournal.biomedcentral.com/articles/10.1186/s13223-022-00685-z
Background One of the main barriers to vaccination against SARS-CoV-2 is the fear of developing hypersensitivity reactions to any of its components. Although these reactions are very rare, it is...
Conclusions: Thanks to the allergological and immunohistochemical study, the vaccination protocol could be completed in about half of the patients who presented suspected hypersensitivity reactions to SARS-CoV-2 vaccines. IDTs with vaccines could be a valuable method for assessing the immunogenicity of the vaccines.
Asthma Outcome Measures Before and After the COVID-19 Outbreak Among the Pediatric Population in a Community Hospital
Background The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic is a global health threat that has affected patient care enormously. Moderate to severe asthma was listed as a risk...
Conclusion: Among a majority African American pediatric population, there were significant improvements in asthma outcomes after COVID-19 societal changes when compared to before COVID-19 based on outcome variables.
Brain motor and fear circuits regulate leukocytes during acute stress - Nature
Source : https://www.nature.com/articles/s41586-022-04890-z
The nervous and immune systems are intricately linked1. Although psychological stress is known to modulate immune function, mechanistic pathways linking stress networks in the brain to peripheral leukocytes remain poorly...
Collectively, these data show that distinct brain regions differentially and rapidly tailor the leukocyte landscape during psychological stress, thus calibrating the immune system’s capacity to respond to physical threats.
Occurrence and transmission potential of asymptomatic and presymptomatic SARS-CoV-2 infections: Update of a living systematic review and meta-analysis

Conclusions: Based on studies published up to July 2021, most SARS-CoV-2 infections were not persistently asymptomatic, and asymptomatic infections were less infectious than symptomatic infections. Summary estimates from meta-analysis may be misleading when variability between studies is extreme and prediction intervals should be presented....
