The widespread use of antibiotics, which wastewater treatment plants (WWTPs) cannot fully remove, in human and veterinary medicine leads to their release into wastewater, resulting in the contamination of aquatic environments. Bivalves can accumulate these antibiotics, posing a risk to shellfish consumers, including potential antimicrobial resistance. This study aimed to assess how three cooking methods-marinating, steaming, and grilling-affect the concentration of 33 different antibiotics in bivalves fortified at the level of maximum residue limit (MRL) and twice the MRL (2MRL).

Introduction And Objectives: International guidelines for the diagnosis of Hypersensitivity Pneumonitis (HP) have improved the diagnostic standardization of this heterogeneous interstitial lung disease. Our goal was to determine how the final multidisciplinary discussion confidence level for suspected fibrotic HP (fHP) can be impacted by the application of different guidelines validated in this context.

Materials And Methods: Retrospective study including patients submitted to transbronchial lung cryobiopsy (TBLC) with a final multidisciplinary meeting diagnosis of fHP.

Objective: The frequency of obstructive sleep apnea (OSA) in patients with idiopathic pulmonary fibrosis (IPF) is high. The clinical course of non-IPF interstitial lung disease (ILD) can be similar to that of IPF. We sought to assess the frequency and predictors of OSA in patients with non-IPF fibrotic ILD, as well as the impact of positive airway pressure (PAP) therapy on the quality of life of such patients.

Introduction: Progressive pulmonary fibrosis (PPF) corresponds to any fibrotic interstitial lung disease (ILD) other than idiopathic pulmonary fibrosis (IPF) that presents clinical, physiological and/or radiological evidence of disease progression similar to IPF. Matrix metalloproteinases (MMPs) have been implicated in the pathogenesis of pulmonary fibrosis and are associated with disease progression and reduced survival in IPF and other fibrotic ILDs. This study aimed to investigate the role of serum levels of MMP-1 and MMP-7 in patients with fibrotic non-IPF ILD as possible biomarkers of patients at risk of developing PPF.

Article Synopsis
  • Adult haematopoietic stem cells (HSCs) are essential for creating blood and immune cells, and their function is influenced by signaling pathways like JAK/STAT, specifically through the activation of STAT5.
  • STAT5 deficiency leads to decreased ability for HSCs to self-renew and repopulate various blood lineages, as well as increased differentiation and reduced quiescence, caused by both loss of traditional pSTAT5 signaling and distinct roles played by unphosphorylated STAT5 (uSTAT5).
  • The study suggests that targeting the JAK1/2 pathway with inhibitors like ruxolitinib can improve HSC maintenance and reduce differentiation, potentially providing a strategy for enhancing stem cell function
