Bronchopulmonary Dysplasia with Pulmonary Hypertension Associates with Loss of Semaphorin Signaling and Functional Decrease in FOXF1 Expression.

Lung injury in preterm infants leads to structural and functional respiratory deficits, with a risk for bronchopulmonary dysplasia (BPD) that in its most severe form is accompanied by pulmonary hypertension (PH). To examine cellular and molecular dynamics driving evolving BPD in humans, we performed single-cell RNA sequencing of preterm infant lungs in early stages of BPD and BPD+PH compared to term infants. Analysis of the endothelium revealed a unique aberrant capillary cell-state primarily in BPD+PH marked by expression.

A Large Postmortem Database of COVID-19 Patients Can Inform Disease Research and Public Policy Decision Making.

Context.—: Autopsies performed on COVID-19 patients have provided critical information about SARS-CoV-2's tropism, mechanisms of tissue injury, and spectrum of disease.

Objective.

Serum lipoprotein subfractions are associated with the periodontal status: Results from the population-based cohort SHIP-TREND.

Aim: To investigate the medium-term associations of serum protein subfractions derived from proton nuclear magnetic resonance ( H-NMR) spectroscopy with periodontitis and tooth loss.

Materials And Methods: A total of 3031 participants of the cohort Study of Health in Pomerania (SHIP-TREND) were included. In addition to conventional serum testing, serum lipoprotein contents and subfractions were analysed by H-NMR spectroscopy.

Parent knowledge regarding food selection for children with PKU: Results of a survey in the United States.

Objectives: Dietary treatment is the main therapy for most patients with phenylketonuria (PKU). Parental knowledge regarding food selection is crucial to ensure adequate metabolic control and brain development during childhood and to promote lifelong adherence and healthy dietary behavior in the offspring. The aims of this study were to assess whether parental or caregiver knowledge regarding nutritional selection for children with PKU is in accordance with medical recommendations and to evaluate factors that influence their level of knowledge.
