Respiratory physiological changes post initiation of neurally adjusted ventilatory assist in preterm infants with evolving or established bronchopulmonary dysplasia.
Eur J Pediatr

Neonatal Intensive Care Centre, St George's University Hospitals NHS Foundation Trust, London, SW17 0QT, UK.
To assess respiratory changes after neurally adjusted ventilatory assist (NAVA) initiation in preterm infants with evolving or established bronchopulmonary dysplasia (BPD). Premature infants born less than 32 weeks gestation with evolving or established BPD initiated on invasive or non-invasive (NIV) NAVA were included. Respiratory data: PCO and SpO₂/FiO₂ (S/F) ratio before and at 4, 24, 48 h post-NAVA initiation were collected.

Unlabelled: During infection, bacterial pathogens rely on secreted virulence factors to manipulate the host cell. However, in gram-positive bacteria, the molecular mechanisms underlying the folding and activity of these virulence factors after membrane translocation are not clear. Here, we solved the protein structures of two secreted parvulin and two secreted cyclophilin-like peptidyl-prolyl isomerase (PPIase) ATP-independent chaperones found in gram-positive streptococcal species.

Internal Medicine, Mercy Health St. Vincent Medical Center, Toledo, USA.
We present a case of spontaneous hemorrhage in an emphysematous bulla, complicated by anticoagulation. Bullous emphysema is a well-recognized complication of chronic obstructive pulmonary disease (COPD), and a rare manifestation is hemorrhage into preexisting pulmonary bullae. A 69-year-old male patient presented to the emergency department with hemoptysis, shortness of breath, and productive cough.

Transplant Direct
March 2024
Department of Respiratory Medicine, Alfred Health, Melbourne, Australia.
Background: Parenthood after lung transplantation (LuTx) is uncommon. Although data exist regarding practice patterns surrounding pregnancy after heart transplantation, there are no data specific to LuTx recipients and parenthood more broadly.
Methods: We conducted a voluntary, anonymous online survey between October and December 2021.
Nebulized aminoglycosides for ventilator-associated pneumonia: Methodological considerations and lessons from experimental studies.

Aminoglycosides are concentration-dependent antibiotics exerting a bactericidal effect when concentrations at the site of infection are equal to or greater than 5 times the minimum inhibitory concentrations (MIC). When administered intravenously, they exhibit poor lung penetration and high systemic renal and ototoxicity, imposing to restrict their administration to 5 days. Experimental studies conducted in anesthetized and mechanically ventilated sheep and pigs provide evidence that high doses of nebulized aminoglycosides induce a rapid and potent bacterial killing in the infected lung parenchyma.
