Delayed-onset pulmonary insufficiency in primates resuscitated from hemorrhagic shock

Abstract

Forty-one unanesthetized cynomolgus monkeys were subjected to 2 hours of hemorrhagic hypotension at various mean arterial pressures (MAP) between 40 and 60 mm Hg. Resuscitation and maintenance of MAP were provided by lactated Ringer's solution and homologous blood. Thirty-eight per cent (57% of those surviving greater than 24 hours) developed a delayed-onset (18 to 24 hours) pulmonary insufficiency in spite of good urinary output, and which did not respond to furosemide. The group in which this caused death (24%) showed significantly decreased PaO2, PaCO2, dynamic compliance, and FECO2, and increased minute volume, Qs/Qt, pulmonary artery pressure, and VD/VT before death. Their lungs were heavier, with abnormal pressure/volume curves and increased minimum surface tension. During the entire post-resuscitation phase, this group remained in a high-output, low-resistance hemodynamic state in contract to survivors and those dying of shock. The implications regarding current practices of monitoring and resuscitating patients with traumatic shock are discussed.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Synapse Loss as Therapeutic Target in MS

As we age, the number of synapses present in the human brain starts to decline, but in neurodegenerative diseases this occurs at an accelerated rate. In MS, it has been shown that there is a reduction in synaptic density, which presents a potential target for treatment. Here is the latest research on synapse loss as a therapeutic target in MS.

Artificial Intelligence in Cardiac Imaging

Artificial intelligence (ai) techniques are increasingly applied to cardiovascular (cv) medicine in cardiac imaging analysis. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

Social learning involves learning new behaviors through observation, imitation and modeling. Follow this feed to stay up to date on the latest research.

Cell Atlas of the Human Eye

Constructing a cell atlas of the human eye will require transcriptomic and histologic analysis over the lifespan. This understanding will aid in the study of development and disease. Find the latest research pertaining to the Cell Atlas of the Human Eye here.

Single Cell Chromatin Profiling

Techniques like ATAC-seq and CUT&Tag have the potential to allow single cell profiling of chromatin accessibility, histones, and TFs. This will provide novel insight into cellular heterogeneity and cell states. Discover the latest research on single cell chromatin profiling here.
