Invasive Community-Onset Gram-Positive Infections From July 2018 Through December 2022 at 2 Children's Hospitals.

Background: Invasive infections caused by Streptococcus pyogenes (invasive group A streptococcus [iGAS]) and Streptococcus pneumoniae (invasive pneumococcal disease [IPD]) decreased substantially at the beginning of the COVID-19 pandemic. Our study sought to evaluate the extent of this decrease and the trends of these infections since reversion of societal adjustments incident to the pandemic. We also wanted to compare the frequency of these infections with invasive community-onset Staphylococcus aureus (I-CO-SA) infections and common respiratory viral infections in this period. Methods: Cases of iGAS, IPD, and I-CO-SA infections were identified prospectively and retrospectively at 2 large US children's hospitals by positive cultures from July 2018 through December 2022. Admission data were used to estimate frequency. For comparison, rates of respiratory syncytial virus (RSV), influenza, and SARS-CoV-2 were estimated by the number of positive viral test results at each institution. Results: I-CO-SA infections showed little variation in the study period. Rates of iGAS infection and IPD decreased by 46% and 44%, respectively, from 2019 to 2020, coinciding with a substantial decrease in RSV and influenza. In 2022, RSV and influenza infection rates increased to prepandemic winter season rates, coinciding with a return to prepandemic rates of IPD (225% increase from 2021 to 2022) and a surge above prepandemic rates of iGAS infections (543% increase from 2021 to 2022). Conclusions: The COVID-19 pandemic had an unexpected influence on IPD and iGAS infections that was temporally related to changes in rates of viral infections.

Sensory and nutritional quality of white rice after residential storage for up to 30 years.

Rice is a staple food that may be packaged for long-term storage to ameliorate unpredictable circumstances such as crop failures and natural disasters. The sensory and nutritional quality of 18 samples of long grain white rice (11 regular, 7 parboiled) packaged in cans stored up to 30 years at ambient temperature in residential locations was evaluated. Hedonic scores for overall liking ranged from 5.6 to 6.6 (9-point scale) and all samples regardless of age scored above 5, "neither like nor dislike". All but one 30-year parboiled sample were considered acceptable for everyday use by greater than 50% of panelists, and for emergency use by over 88% of panelists. Thiamin concentrations ranged from 0.5 to 3.6 µg/g. Although vitamin stability appears to be limited, rice retains much of its sensory quality over time and the presence of minerals and other stable macronutrients may justify its inclusion in a long-term food storage regimen.
