Background&aims: Non-invasive tests (NITs) for ruling-out clinical significant portal hypertension (CSPH) and high-risk varices (HRV) in patients with primary biliary cholangitis(PBC) and compensated advanced chronic liver disease (cACLD) are lacking. We evaluated NITs in these patients and the influence of cholestasis on their performance.

Methods: Consecutive patients from the "Italian PBC registry" and two UK large-volume PBC referral centres with upper endoscopy within 6 months from biochemical evaluation and transient elastography were included.

Article Synopsis
  • This study examines how early clinical hepatic decompensation (CHD) affects the overall survival (OS) of patients with unresectable hepatocellular carcinoma (uHCC) who are receiving systemic treatments like Atezolizumab plus Bevacizumab or Sorafenib.
  • Researchers analyzed data from the IMbrave150 trial and found that patients experiencing early CHD had a significantly higher risk of mortality, indicating a poor prognosis.
  • The study identifies specific factors (like ALBI grade, INR levels, and macrovascular invasion) that put patients at a greater risk for CHD, suggesting that these could be useful in future clinical trials to better assess patient outcomes.

is a significant concern in the food industry due to its association with outbreaks of listeriosis, particularly affecting vulnerable populations. High-throughput technologies such as RNA sequencing (RNA-seq) and proteomics offer valuable insights into the molecular responses of to stress environments. In this study, a combined transcriptomic and immunoproteomic approach was applied to explore the stress response mechanisms of the strain ST7, which was responsible for an outbreak in central Italy.

Importance: The recent change in terminology from nonalcoholic fatty liver disease (NAFLD) to metabolic dysfunction-associated fatty liver disease (MAFLD) and metabolic dysfunction-associated steatotic liver disease (MASLD) highlights the link between hepatic steatosis and metabolic dysfunction, taking out the stigmata of alcohol.

Objective: We compared the effects of NAFLD and MAFLD definitions on the risk of overall and cardiovascular (CV) mortality, liver-related events (LRE), nonfatal CV events (CVE), chronic kidney disease (CKD), and extra-hepatic cancers (EHC).

Data Sources And Study Selection: We systematically searched four large electronic databases for cohort studies (published through August 2023) that simultaneously used NAFLD and MAFLD definitions for examining the risk of mortality and adverse CV, renal, or oncological outcomes associated with both definitions.

Background: Endoscopic ultrasound (EUS) is the most sensitive method for diagnosing chronic pancreatitis (CP) in its early stages, and Rosemont Classification (RC) is used for its evaluation. Data on the correlation between EUS features and pancreatic exocrine insufficiency (PEI) are limited. We investigated the correlation between the EUS findings and PEI.

Wastewater treatment plants are hotspots for the release of antimicrobial resistant pathogenic bacteria into aquatic ecosystems, significantly contributing to the cycle of antimicrobial resistance. Special attention should be paid to antimicrobial resistant ESKAPE bacteria, which have been identified as high-priority targets for control measures. Among them, Klebsiella pneumoniae is particularly noteworthy.

Usutu virus (USUV), an arbovirus from the Flaviviridae family, genus Flavivirus, has recently gained increasing attention because of its potential for emergence. After his discovery in South Africa, USUV spread to other African countries, then emerged in Europe where it was responsible for epizootics. The virus has recently been found in Asia.

Article Synopsis
  • The study investigates the impact of hepatic functional reserve and tumor progression on overall survival in patients with hepatocellular carcinoma (HCC) undergoing combination immunotherapy with atezolizumab and bevacizumab.
  • Out of 571 patients analyzed, a significant portion developed tumor progression, while a smaller group experienced hepatic decompensation, both of which greatly affected survival outcomes.
  • Key predictors of poor survival included hepatic decompensation, advanced tumor progression, and specific baseline liver function metrics, with effective antiviral treatment showing potential protective effects against decompensation in patients with viral causes of HCC.

Importance: Whether patients with Child-Pugh class B (CP-B) cancer with unresectable hepatocellular carcinoma (uHCC) benefit from active anticancer treatment vs best supportive care (BSC) is debated.

Objective: To evaluate the association of immune checkpoint inhibitor (ICI)-based therapies vs BSC with overall survival (OS) of patients with uHCC and CP-B liver dysfunction.

Design, Setting, And Participants: This retrospective, multicenter, international clinical case series examined data of patients with CP-B with uHCC who were receiving first-line ICI-based regimens from September 2017 to December 2022 whose data were extracted from an international consortium and compared with a cohort of patients with CP-B receiving BSC.

Background: Atezolizumab + bevacizumab represent the current standard of care for first-line treatment of advanced hepatocellular carcinoma (HCC). However, direct comparison with other combination treatments including immune checkpoint inhibitors (ICI) + tyrosine kinase inhibitors (TKIs) are lacking.

Objectives: This network meta-analysis (NMA) aims to indirectly compare the efficacy and the safety of first-line systemic therapies for unresectable advanced HCC.

Microplastic contamination is a growing marine environmental issue with possible consequences for seafood safety. Filter feeders are the target species for microplastic (MPs) pollution because they filter large quantities of seawater to feed. In the present study, an experimental contamination of was conducted using a mixture of the main types of MPs usually present in the seawater column (53% filaments, 30% fragments, 3% granules) in order to test the purification process as a potential method for removing these contaminants from bivalves intended for human consumption.

The spread of extended-spectrum β-lactamase (ESBL)-producing is a major public health issue. Bivalves are filter-feeder animals capable of bioaccumulating the microorganisms present in water. This physiological characteristic makes them both good indicators of environmental contamination and possible carriers of pathogenic bacteria, including those resistant to antimicrobials.

Article Synopsis
  • The study examines how SARS-CoV-2, the virus causing COVID-19, sheds in both nasopharyngeal and stool samples from children, aiming to understand potential oral-fecal transmission, especially in asymptomatic cases.
  • It involved 71 children (64 symptomatic and 7 asymptomatic), with samples collected weekly, revealing that 21.1% of children had detectable viral RNA in their stool.
  • The findings showed that while the virus RNA can be present in both types of samples for up to 21 days (nasopharyngeal) and 14 days (fecal), the virus was not successfully isolated from stool samples.
