Bronchopulmonary dysplasia (BPD) remains the most common complication of premature birth, imposing a significant and potentially life-long burden on patients and their families. Despite advances in our understanding of the mechanisms that contribute to patterns of lung injury and dysfunctional repair, current therapeutic strategies remain non-specific with limited success. Contemporary definitions of BPD continue to rely on clinician prescribed respiratory support requirements at specific time points. While these criteria may be helpful in broadly identifying infants at higher risk of adverse outcomes, they do not offer any precise information regarding the degree to which each compartment of the lung is affected. In this review we will outline the different pulmonary phenotypes of BPD and discuss important features in the pathogenesis, clinical presentation, and management of these frequently overlapping scenarios.

Identifying inflammation-induced leukocyte subsets and their derived circulating factors has been instrumental in understanding the progession of ALI/ARDS. Nevertheless, how primary inflammation-induced non-leukocyte populations in distal organs contribute to ALI/ARDS remains poorly defined. Here, we report one population of erythroblast-like cells (Ter-cells) deriving from megakaryocyte- erythroid progenitor cells with a unique Ter-119+CD45-CD71+ phenotype in ALI/ARDS.

Aims: Atrial septal defect (ASD) and partial abnormal pulmonary venous connection (PAPVC) are noncyanotic congenital heart defects (CHD) that produce a left-to-right shunt. This single-center retrospective study aimed to assess the hemodynamic impact of isolated ASD, isolated PAPVC, and ASD-associated PAPVC using cardiovascular magnetic resonance (CMR).
Methods And Results: From our CMR registry (2002-2024), 110 patients were included: isolated ASD (n=64), isolated PAPVC (n=18), ASD-associated PAPVC (n=28, mostly sinus venosus septal defects).
Introduction And Objectives: The fractional exhaled fraction of nitric oxide (FeNO) is used in clinical practice for asthma diagnosis, phenotyping, and therapeutic management. Therefore, accurate thresholds are crucial. The normal FeNO values over lifespan in a respiratory healthy population and the factors related to them remain unclear.

Aging is a risk factor for several chronic conditions, including intervertebral disc degeneration and associated back pain. Disc pathologies include loss of reticular-shaped nucleus pulposus cells, disorganization of annulus fibrosus lamellae, reduced disc height, and increased disc bulging. Sonic hedgehog, cytokeratin 19, and extracellular matrix proteins are markers of healthy disc.

Background: Angiogenesis is mediated by endothelial progenitor cells (EPCs) derived from bone-marrow. In this prospective study, we tried to investigate the clinical utility of circulating EPCs in lung cancer (LC) patients.
Materials And Methods: Flow cytometry technique was used to assess circulating EPCs according to the immuno-phenotype CD45 CD34 CD133 CD146 mononuclear cells.
