Diffuse parenchymal lung diseases (DPLD) or Interstitial lung diseases (ILD) are a heterogeneous group of lung conditions with common characteristics that can progress to fibrosis. Within this group of pneumonias, idiopathic pulmonary fibrosis (IPF) is considered the most common. This disease has no known cause, is devastating and has no cure. Chronic lesion of alveolar type II (ATII) cells represents a key mechanism for the development of IPF. ATII cells are specialized in the biosynthesis and secretion of pulmonary surfactant (PS), a lipid-protein complex that reduces surface tension and minimizes breathing effort. Some differences in PS composition have been reported between patients with idiopathic pulmonary disease and healthy individuals, especially regarding some specific proteins in the PS; however, few reports have been conducted on the lipid components. This review focuses on the mechanisms by which phospholipids (PLs) could be involved in the development of the fibroproliferative response.

The abnormally viscous and thick mucus is a hallmark of cystic fibrosis (CF). How the mutated CF gene causes abnormal mucus remains an unanswered question of paramount interest. Mucus is produced by the hydration of gel-forming mucin macromolecules that are stored in intracellular granules prior to release.

Background: The Coronavirus Disease (COVID-19) has had a significant impact on healthcare organizations, leading to a reduction in screening. The pandemic period has caused important psychological repercussions in the most fragile patients.
Objectives: This study aimed to assess the levels of depression, anxiety, peri-traumatic stress, and physical symptoms in patients undergoing colposcopy during the COVID-19 pandemic and to compare these data with the post-pandemic period.
Circulating Tumor DNA Detection for Recurrence Monitoring of Stage I Non-Small Cell Lung Cancer Treated With Microwave Ablation.

Purpose: As microwave ablation continues to be used in patients with inoperable stage I non-small cell lung cancer (NSCLC), it is particularly important to monitor efficacy. Whether plasma ctDNA detection can predict its efficacy should be illustrated.
Methods: We recruited 43 patients with inoperative stage I NSCLC, all of whom underwent biopsy-synchronous microwave ablation (MWA).

Sepsis-induced acute lung injury (ALI) is a common acute and severe reason of death in the intensive care unit. Although the pathogenesis is complicated and multifactorial, elevated inflammation and oxidative stress are considered as fundamental mechanisms for the progression of ALI. Anemonin is a natural compound with diverse biological properties including anti-inflammatory and anti-oxidative effects.
