The experimental studies in rabbits have shown the pulmonary surfactant to participate in inactivation of kinins in the lung in peritonitis which results in the destruction of surfactant. Its deficiency is responsible for the development of pulmonary complications.

Objective: To explore the risk factors for the reactivate of retinopathy of prematurity (ROP) after intravitreal injection of anti-vascular endothelial growth factor (VEGF) and to construct a nomogram model to predict the risk of ROP reactivate.
Methods: A retrospective analysis was conducted on 185 ROP children who underwent anti-VEGF treatment at the First Affiliated Hospital of Zhengzhou University from January 2017 to October 2023. They were randomly divided into a training set (129 cases) and a validation set (56 cases) at a ratio of 7:3.

Background And Aim: NK cells and NK-cell-derived cytokines were shown to regulate neutrophil activation in acute lung injury (ALI). However, the extent to which ALI regulates lung tissue-resident NK (trNK) activity and their molecular phenotypic alterations are not well defined. We aimed to assess the impact of 1,25-hydroxy-vitamin-D3 [1,125(OH)D] on ALI clinical outcome in a mouse model and effects on lung trNK cell activations.

Since its outbreak, the novel coronavirus (COVID-19) has significantly impacted the pediatric population. Pulmonary surfactant dysfunction has been linked to other respiratory diseases in children and COVID-19 in adults, but its role in COVID-19 severity remains unclear. We hypothesized that elevated surfactant protein (SP) levels and single nucleotide polymorphisms (SNPs) of SP genes are associated with severe COVID-19 in children.

Ozone (O) is a ubiquitous pollutant known to produce acute, transient inflammation through oxidative injury and inflammation. These effects are exacerbated in susceptible populations, such as the elderly and those exhibiting genetic mutations in central nodes of pulmonary function. To comprehend the impact of these predisposing factors, the present study examines structural, mechanical, and immunological responses to single acute O exposure (0.

The administration of surfactant aerosol therapy to preterm infants receiving continuous positive airway pressure (CPAP) respiratory support is highly challenging due to small flow passages, relatively high ventilation flow rates, rapid breathing and small inhalation volumes. To overcome these challenges, the objective of this study was to implement a validated computational fluid dynamics (CFD) model and develop an overlay nasal prong interface design for use with CPAP respiratory support that enables high efficiency powder aerosol delivery to the lungs of preterm infants when needed (i.e.
