We tested the hypothesis that at the early phase of acute lung injury (ALI) the degree of endothelium injury may predict lung parenchyma remodelling For this purpose, two models of extrapulmonary ALI induced by Escherichia col: lipopolysaccharide (ALI-LPS) or cecal ligation and puncture (ALI-CLP) were developed in mice At day 1, these models had similar degrees of lung mechanical compromise, epithelial damage, and intraperitoneal inflammation, but endothelial lesion was greater in ALI-CLP A time course analysis revealed, at day 7 ALI-CLP had higher degrees of epithelial lesion, denudation of basement membrane, endothelial damage, elastic and collagen fibre content, neutrophils in bronchoalveolar lavage fluid (BALF), peritoneal fluid and blood, levels of interleukin-6, KC (murine analogue of IL-8), and transforming growth factor-beta in BALF Conversely, the number of lung apoptotic cells was similar in both groups In conclusion, the intensity of fibroelastogenesis was affected by endothelium injury in addition to the maintenance of epithelial damage and intraperitoneal inflammation.

Summary: Over the last decade, management of acute respiratory distress syndrome (ARDS) has advanced significantly in terms of supportive and pharmacologic therapies. Lung protective mechanical ventilation is crucial for ARDS management, with recommendations including low tidal volume, plateau pressure, and driving pressure. Other therapies such as recruitment maneuvers and prone positioning are considered for severe ARDS cases. Despite extensive research, effective pharmacotherapies for ARDS are yet to be found, but sub-phenotypes of ARDS have shown potential for personalized pharmacologic treatments.

Lucas Rodrigues de Moraes, Chiara Robba, Denise Battaglini, Paolo Pelosi, Patricia R. M. Rocco, Pedro Leme Silva

Summary: Coronavirus disease (COVID-19) is caused by the SARS-CoV-2 virus and can lead to severe respiratory failure requiring mechanical ventilation (MV). Noninvasive respiratory support (NRS), MV, and ECMO are used as treatment strategies. Lung imaging advances have improved understanding of COVID-19 and ventilatory strategies. This review aims to discuss evidence on NRS devices and strategies, personalized MV management based on COVID-19 pathophysiology, and the use of rescue strategies like ECMO in critically ill COVID-19 patients.

Fluid management strategies and their interaction with mechanical ventilation: from experimental studies to clinical practice

Eduardo Butturini de Carvalho, Denise Battaglini, Chiara Robba, Manu L. N. G. Malbrain, Paolo Pelosi, Patricia Rieken Macedo Rocco, Pedro Leme Silva

Summary: Ventilatory management can be influenced by restrictive and liberal fluid strategies, potentially leading to damage to distal organs in critically ill patients. Pre-clinical studies have assessed the effects of different fluid strategies on ventilator-induced lung injury, both during and after changes in positive end-expiratory pressure (PEEP). Patients on mechanical ventilation can receive intravenous fluids through either restrictive or liberal fluid management. However, there is a lack of clear differentiation between these two strategies in the literature. Restrictive fluid management may result in hypoperfusion and distal organ damage, while liberal fluid strategy can cause various complications such as endothelial shear stress, glycocalyx damage, cardiovascular issues, lung edema, and distal organ dysfunction. The combination of liberal fluids and pressure-support ventilation, but not pressure control ventilation, may lead to further lung damage. This narrative review aims to provide a better understanding of the interaction between different fluid and ventilation strategies and their impact on the lungs and distal organs. The weaning phase of mechanical ventilation and the deresuscitation phase are not covered in this review.

Disinhibition does not play a role in endomorphin-2-induced changes in inspiratory motoneuron output produced by in vitro neonatal rat preparations

Stephen M. Johnson, Maia G. Gumnit, Sarah M. Johnson, Tracy L. Baker, Jyoti J. Watters

Summary: Low-level activation of mu-opioid receptors can increase the amplitude of inspiratory bursts in neonatal rat brainstem-spinal cord preparations. Endomorphin-2, an endogenous ligand for these receptors, was found to have similar effects. Disinhibition of inhibitory synaptic transmission may not be involved in the changes induced by endomorphin-2, and different mechanisms may underlie the increase in burst amplitude and decrease in burst frequency.
