AI Article Synopsis
- The proposed diagnostic criteria for cirrhotic cardiomyopathy (CCM) includes echocardiographic evidence of heart dysfunction and can involve abnormalities in heart function or increased biomarkers in patients with cirrhosis.
- Tissue Doppler imaging (TDI) is more accurate than conventional 2D echocardiography in detecting cardiac dysfunction in these patients.
- A meta-analysis of 12 studies found a CCM prevalence of 61% using the 2005 criteria with standard echocardiography and 45% with TDI, suggesting that conventional methods may overdiagnose CCM in cirrhotic patients.
Article Abstract
The proposed diagnostic criteria for cirrhotic cardiomyopathy (CCM), defines it as documented echocardiographic findings of systolic or diastolic dysfunction (using conventional 2D echocardiogram), with or without electrophysiological abnormalities or elevated biomarkers in cirrhotic patients. In comparison to 2D echocardiogram, tissue Doppler imaging (TDI) has better sensitivity and specificity, when evaluating for cardiac dysfunction. This meta-analysis of 12 selected cohort studies attempted to estimate the pooled prevalence of CCM using either conventional echocardiography or TDI. Using the 2005 criteria, the pooled prevalence of CCM is 61% (P = 0.106). When TDI is used, the prevalence of CCM is at 45% (P = 0.088). Analyzing data of 615 cirrhotic patients, this study estimates the mean population-specific echocardiographic values of cirrhotic patients, including left ventricle ejection fraction (63.52%), deceleration time (229.04 ms), isovolumetric relaxation time (87.71 ms) and E/A ratio (1.04). In comparison to TDI, using standard 2D echocardiography leads to overdiagnosis of CCM.

Liver-Secreted Extracellular Vesicles Promote Cirrhosis-Associated Skeletal Muscle Injury Through mtDNA-cGAS/STING Axis.

Skeletal muscle atrophy (sarcopenia) is a serious complication of liver cirrhosis, and chronic muscle inflammation plays a pivotal role in its pathologenesis. However, the detailed mechanism through which injured liver tissues mediate skeletal muscle inflammatory injury remains elusive. Here, it is reported that injured hepatocytes might secrete mtDNA-enriched extracellular vesicles (EVs) to trigger skeletal muscle inflammation by activating the cGAS-STING pathway.

Background: The July effect in US teaching hospitals has been studied with conflicting results. We aimed to evaluate the effect of physician turnover in July on the clinical outcomes of patients hospitalized with cirrhosis.
Methods: We utilized the Nationwide Inpatient Sample database (2016-2019) to identify patients hospitalized with cirrhosis and liver-related complications (variceal bleeding, hepatorenal syndrome, acute-on-chronic liver failure).

Introduction: Despite treatment with antibiotic therapy, spontaneous bacterial peritonitis (SBP) accounts for approximately 20-40% mortality in hospitalized patients. The data is scarce regarding mortality predictors in SBP. Recently, multiple factors have been studied for effectiveness in prognosis prediction in SBP.

Background And Aims: The performance of neurodegenerative biomarkers-neurofilament light chain (NfL), glial fibrillary acidic protein (GFAP), tau, and ubiquitin carboxy-terminal hydrolase L1 (UCHL1)-in diagnosing minimal hepatic encephalopathy (MHE) has not been systematically evaluated, simultaneously, nor have their associations with the development of overt hepatic encephalopathy (OHE). This study aimed to evaluate the performance of plasma NfL, GFAP, tau, and UCHL1 in diagnosing MHE and predicting the development of OHE in Chinese patients with hepatic cirrhosis.
Methods: In this prospective study, 124 patients with hepatic cirrhosis were recruited.

Hepatic hydrothorax (HH) is a severe cirrhosis complication requiring early diagnosis and appropriate management. This study aimed to assess the impact of HH on the disease severity and mortality of cirrhotic patients and compare their clinical and biological profiles with those of patients without HH. This retrospective study involved 155 patients diagnosed with cirrhosis, of whom 31 had HH.
