Changes of EEG and pulmonary venous admixture during a protein load in patients with cirrhosis

Abstract

21 patients with cirrhosis of the liver and 24 control patients were studied before and after a protein load (120 g protein per day during one week). An EEG was recorded and a visual assessment of frequency pattern was performed. Venous admixture was estimated during hyperoxia. According to the EEG frequency pattern the patient group with cirrhosis was subdivided into those with EEG slowing after the protein load (n = 7) and those without (n = 14). The following results were obtained: 1) Resting arterial blood gases did not change in either group. 2) There was a significant increase of the AaD02 (difference between alveolar p02 and peripheral arterial p02) in cirrhotics and controls. 3) The increase in AaD02 was significantly larger in those cirrhotics showing EEG slowing compared to those without EEG - slowing or to the controls. 4) Fractional venous admisture increased significantly in those cirrhotics showing EEG slowing. There was no significant change in those patients who did not show EEG changes or in the controls.

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.

Synthetic Genetic Array Analysis

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

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.

Head And Neck Squamous Cell Carcinoma

Squamous cell carcinomas account for >90% of all tumors in the head and neck region. Head and neck squamous cell carcinoma incidence has increased dramatically recently with little improvement in patient outcomes. Here is the latest research on this aggressive malignancy.
