The objectives of this study were to investigate the in vitro immune-modulatory effects of monoglycerides and zinc glycinate with porcine alveolar macrophages (PAM) and their impact on epithelial barrier integrity using the intestinal porcine enterocyte cell line (IPEC-J2). Cell viability was assessed using a Vybrant MTT assay to determine the appropriate dose range of monoglyceride blend (C4, C8, and C10) and zinc glycinate. In experiment 1, IPEC-J2 cells (5 × 105 cells/mL) were seeded and treated with each compound (monoglycerides: 0, 25, 100, 250, 500, and 1,000 µg/mL; zinc glycinate: 0, 2, 5, 12.

In this study, a combination of butyric, caprylic, and capric fatty acid monoglycerides was investigated to promote intestinal integrity and host defenses in weanling pigs infected with ETEC. A total of 160 pigs were allotted to treatment groups based on weight and sex.

Previous research suggests an increased risk of severe COVID-19 illness and stillbirth in pregnant people during delta variant predominance in 2021; however, those studies did not assess timing of infection during pregnancy, and few of them described COVID-19 vaccination status.
Objective: Using a large population-based cohort, this study compared pregnancy and infant outcomes and described demographic and clinical characteristics of pregnant people with SARS-CoV-2 infection prior to and during the delta variant period.
