Hemodynamic data in lesional pulmonary edemas

Pulmonary edema due to disorders in alveolo-capillary permeability (or lesional) are differentiated from hemodynamic pulmonary edema by the fact that they arise in spite of normal pulmonary capillary pressure (PCP). A hemodynamic study was carried out in 42 cases of lesional P.E. The PCP was normal whatever the date of the examination and the gravity of the P.E. Pulmonary arterial hypertension was only found in the presence of frank hypoxemia and disappeared with the correction of the latter. If there was no hemodynamic profile due to P.E. itself, its etiology sometimes induced a hyperkinetic or hypovolemic syndrome. Finally it was apparent that PCP was significantly higher- although normal- at the initial stage than after 6 hours of P.E.; that an elevation in PCP of only a few mm Hg by the perfusion of colloids aggravated the P.E., that despite the normal value for the PCP dehydration evidently improved hematosis. Thus this study confirms that numerous cases of P.E. can occur while the PCP remains normal. It also confirms the noxious nature of too abundant perfusions in these cases and the effectiveness of dehydration.

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.

Bone Marrow Neoplasms

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

LRRK2 & Immunity During Infection

Mutations in the LRRK2 gene are a risk-factor for developing Parkinson’s disease. However, LRRK2 has been shown to function as a central regulator of vesicular trafficking, infection, immunity, and inflammation. Here is the latest research on the role of this kinase on immunity during infection.

Antiphospholipid Syndrome

Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.

Meningococcal Myelitis

Meningococcal myelitis is characterized by inflammation and myelin damage to the meninges and spinal cord. Discover the latest research on meningococcal myelitis here.

Alzheimer's Disease: MS4A

Variants within membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease by recent genome-wide association studies. Here is the latest research.
