Association of Neonatal and Maternal Nasal Microbiome Among Neonates in the Intensive Care Unit.

The neonatal nasal microbiota may help protect neonates in the neonatal intensive care unit from pathogen colonization and infection. This preliminary study characterized the biodiversity of nasal microbiota comparing neonates in the neonatal intensive care unit and their mothers, highlighting the potential of strain sharing between mother-neonate pairs.

Association of Nirmatrelvir/Ritonavir Treatment and COVID-19-Neutralizing Antibody Titers in a Longitudinal Health Care Worker Cohort.

Nirmatrelvir/ritonavir (NMV/r) is used for the treatment of coronavirus disease 2019 (COVID-19) infection. However, rebound COVID-19 infections can occur after taking NMV/r. We examined neutralizing antibodies to the severe acute respiratory syndrome coronavirus 2 spike protein before and after infection in people who did and did not take NMV/r to determine if NMV/r impedes the humoral immune response.
