Physical Activity Levels in Children with Esophageal Atresia and Congenital Heart Disease: A Comparative Multicenter Study.

Aim Of The Study:  Esophageal atresia (EA) is associated with impaired motor development, cardiopulmonary function, and physical activity (PA). Despite missing scientific evidence, this fact is often attributed to associated congenital heart disease (CHD). The aim of this study was to investigate PA in EA patients without CHD compared with CHD patients and healthy controls.

Nurture growth: Ketogenic diet therapy and growth velocity in infants under 12 months with epilepsy - A systematic review and infant data study.

Ketogenic diet therapy (KDT) is well established for the treatment of early epileptic encephalopathies and specific aetiologies; however, the impact on growth in infancy remains controversial. Our aim was to examine the influence of early KDT on growth velocity and height percentiles completing two tasks. First, we systematically reviewed the literature on growth in infants younger than 12 months.

Factors Influencing Breast Milk Antibody Titers during the Coronavirus Disease 2019 Pandemic: An Observational Study.

The COVID-19 pandemic has highlighted the role of breastfeeding in providing passive immunity to infants via specific anti-SARS-CoV-2 antibodies in breast milk. We aimed to quantify these antibodies across different lactation stages and identify influencing factors. This prospective study involved mother-child dyads from Innsbruck University Hospital, Austria, with a positive maternal SARS-CoV-2 test during pregnancy or peripartum between 2020 and 2023.

Exploitation of CD3ζ to enhance TCR expression levels and antigen-specific T cell function.

The expression levels of TCRs on the surface of human T cells define the avidity of TCR-HLA/peptide interactions. In this study, we have explored which components of the TCR-CD3 complex are involved in determining the surface expression levels of TCRs in primary human T cells. The results show that there is a surplus of endogenous TCR α/β chains that can be mobilised by providing T cells with additional CD3γ,δ,ε,ζ chains, which leads to a 5-fold increase in TCR α/β surface expression.
