Development and validation of a new prognostic model for predicting survival outcomes in patients with acute-on-chronic liver failure
2024-10-27
(Press-News.org) Background and Aims
Early determination of prognosis in patients with acute-on-chronic liver failure (ACLF) is crucial for optimizing treatment options and liver allocation. This study aimed to identify risk factors associated with ACLF and to develop new prognostic models that accurately predict patient outcomes.
Methods
We retrospectively selected 1,952 hospitalized patients diagnosed with ACLF between January 2010 and June 2018. This cohort was used to develop new prognostic scores, which were subsequently validated in external groups.
Results
The study included 1,386 ACLF patients and identified six independent predictors of 28-day mortality through multivariate analysis (all p < 0.05). The new score, based on a multivariate regression model, demonstrated superior predictive accuracy for both 28-day and 90-day mortalities, with Areas under the ROC curves of 0.863 and 0.853, respectively (all p < 0.05). This score can be used to stratify the risk of mortality among ACLF patients with ACLF, showing a significant difference in survival between patients categorized by the cut-off value (log-rank (Mantel–Cox) χ2 = 487.574 and 606.441, p = 0.000). Additionally, the new model exhibited good robustness in two external cohorts.
Conclusions
This study presents a refined prognostic model, the Model for end-stage liver disease-complication score, which accurately predicts short-term mortality in ACLF patients. This model offers a new perspective and tool for improved clinical decision-making and short-term prognostic assessment in ACLF patients.

Background and Aims
Hepatocellular carcinoma (HCC) is one of the most fatal malignancies. Epigenetic mechanisms have revealed that noncoding RNAs, such as microRNAs (miRNAs) and circular RNAs (circRNAs), are involved in HCC progression. This study aimed to construct a circRNA-miRNA-mRNA network in HCC and validate one axis within the network.
Methods
HCC-related transcriptome data were obtained from the Gene Expression Omnibus, and HCC-related genes were sourced from GeneCards to identify differentially expressed circRNAs and miRNAs. ...

“Our finding that enhanced melting of Arctic sea-ice likely resulted in significant cooling in northern Europe in the earth’s past is alarming,” says Mohamed Ezat from the iC3 Polar Research Hub, lead author of the new study. “This reminds us that the planet’s climate is a delicate balance, easily disrupted by changes in temperature and ice cover.”
Ice-free summer conditions are expected to occur in the Arctic Ocean from the year 2050 onwards.

San Diego, CA (October 26, 2024) — For kidney transplant recipients experiencing antibody-mediated rejection, the current standard of care involves removing donor-specific antibodies (DSAs) through plasmapheresis (PLEX)—a procedure that removes antibodies from the plasma portion of the blood. Results from a recent clinical trial reveal that an investigational drug called imlifidase, which cleaves and inactivates the type of antibodies that include DSAs, is more effective than PLEX. The research will be presented at ASN Kidney ...

San Diego, CA (October 26, 2024) — IgA nephropathy is an autoimmune kidney disease, and complement, a component of the innate immune system, plays a role in the condition’s pathogenesis. Investigators have developed and tested a novel gene therapy that enters kidney cells and enables them to block complement activation. The research will be presented at ASN Kidney Week 2024 October 23– 27.
The gene therapy, called PS-002, uses a modified virus to treat kidney cells called podocytes. Administration of PS-002 in a mouse model of IgA nephropathy reduced signs of kidney dysfunction, lowered complement ...

San Diego, CA (October 26, 2024) — Chronic active antibody-mediated rejection (caAMR) is a common cause of allograft loss after transplantation, with no approved therapies. Clazakizumab, a monoclonal antibody that targets the inflammatory cytokine interleukin-6 (IL-6), stabilized kidney transplant recipients’ kidney function in a phase 2 trial. Investigators now have data from a phase 3 trial with clazakizumab. The findings from the Phase 3 IMAGINE trial, the largest placebo-controlled study in kidney transplant recipients with caAMR, will be ...

Hyponatremia, or a chronically low blood salt level, is the most common electrolyte disorder in hospitalized patients, and is associated with higher risks of death and re-hospitalization. In a recent trial, 2,173 hospitalized patients with hyponatremia from 9 centers across Europe were assigned to undergo either targeted correction of blood salt levels according to guidelines or to receive routine care for hyponatremia. The primary outcome was the combined ...

Background and objectives
Mesothelioma is an aggressive tumor with a poor prognosis. Histological diagnosis of mesothelioma using limited tissue samples can be challenging. Carbonic anhydrase IX (CAIX) is a transmembrane protein that is overexpressed in a variety of solid tumors. This study aimed to investigate the clinical utility of CAIX expression in the differential diagnosis of pleural mesothelioma from non-small cell lung carcinoma (NSCLC).
Methods
Unstained tissue microarray slides composed of 56 cases of pleural mesothelioma and 82 cases of NSCLC were subjected to immunohistochemical staining using a mouse anti-human antibody against CAIX.
Results
Of the 38 epithelioid mesothelioma ...

Background and objectives
Helicobacter pylori (H. pylori) infection can cause multiple secondary digestive disorders. Some studies have found that polymorphisms in Toll-like receptor (TLR) genes, including TLR10 rs10004195, may be associated with increased susceptibility to H. pylori infection. Despite conflicting reports, we conducted a meta-analysis to clarify the relationship between these factors.
Methods
We conducted an exhaustive review, encompassing all relevant literature up to February 2024, using databases ...

Background and objectives
Nail psoriasis is common in patients with plaque psoriasis and is associated with morbidity, including onychomycosis, which can complicate psoriasis treatments and be difficult to differentiate. Matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry is a fast and simple technique for identifying microorganisms through protein analysis. This study aimed to determine the sensitivity and specificity of MALDI-TOF for diagnosing onychomycosis in patients with nail psoriasis, by using conventional mycological and histological methods as the reference standard.
Methods
A prospective study was conducted on 88 patients with ...
