Seroprevalence and silent infection rate during SARS-CoV-2 pandemic among children and adolescents in Western Pomerania: a multicenter, cross-sectional study-the COVIDKID study.

Background: Limited data on SARS-CoV-2 seroprevalence in rural areas of northern Germany necessitate comprehensive cohort studies. We aimed to evaluate the seroprevalence, silent infection (SI) rates and risk factors for infections among children and adolescents in Western Pomerania from December 2020 to August 2022.

Methods: In this cross-sectional study, serum or plasma samples from children and adolescents (6 months to 17 years) were collected during routine blood draw.

A nutritional program to improve outcome of very low birth weight infants.

Background & Aims: The growth of very low birth weight infants does not match intrauterine trajectories, likely due to inappropriate caloric intake. We therefore investigated whether modification of the standard nutritional schedule can impact postnatal growth.

Methods: We introduced a set of evidence-based strategies in a study group of infants (n = 123): 1) higher maximum intake of intravenous amino acids and lipids; 2) prioritisation of earlier enteral feeding; 3) faster attainment of full enteral feeds; 4) daily adjustment of enteral feeds according to growth trajectory; and 5) utilisation of an electronic pre-structured prescription ordering system that tracks individual growth and energy intake.
