Proteomics identifies potential immunological drivers of postinfection brain atrophy and cognitive decline.

Infections have been associated with the incidence of Alzheimer disease and related dementias, but the mechanisms responsible for these associations remain unclear. Using a multicohort approach, we found that influenza, viral, respiratory, and skin and subcutaneous infections were associated with increased long-term dementia risk. These infections were also associated with region-specific brain volume loss, most commonly in the temporal lobe.

Pediatric Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Vaccines: Perceptions and Attitudes From the Food and Drug Administration Public Commentary.

Authorization of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines for children has ushered in a new phase of the immunization campaign to address the pandemic but has been received with mixed responses from parents, children, and opinion leaders. Herein we consider perceptions and attitudes towards pediatric SARS-CoV-2 vaccines from a Food and Drug Administration (FDA) public commentary reflecting more than 63 000 comments.

SARS-CoV-2 mRNA Vaccine Attitudes as Expressed in U.S. FDA Public Commentary: Need for a Public-Private Partnership in a Learning Immunization System.

As part of the U.S. Food and Drug Administration COVID-19 vaccine review process, public commentary was solicited offering an opportunity to reflect on vaccine attitudes that may impact the uptake of coronavirus vaccines.

Meta-analysis of genome-wide association studies identifies two loci associated with circulating osteoprotegerin levels.

Osteoprotegerin (OPG) is involved in bone homeostasis and tumor cell survival. Circulating OPG levels are also important biomarkers of various clinical traits, such as cancers and atherosclerosis. OPG levels were measured in serum or in plasma.
