Male preference for TERT alterations and HBV integration in young-age HBV-related HCC: implications for sex disparity.

Background/aims: Hepatocellular carcinoma (HCC) exhibits significant sex disparities in incidence, yet its molecular mechanisms remain unclear. We explored the role of telomerase reverse transcriptase (TERT) genetic alterations and hepatitis B virus (HBV) integration, both known major contributors to HCC, in sex-specific risk for HBV-related HCC.

Methods: We examined 310 HBV-related HCC tissues to investigate sex-specific TERT promoter (TERT-pro) mutations and HBV integration profiles, stratified by sex and age, and validated with single-cell RNA sequencing (scRNA-seq) data.

Rifaximin treatment in patients with severe alcoholic hepatitis: A multicenter, randomized controlled, open-label, pilot trial.

Introduction And Objectives: The short-term mortality of severe alcoholic hepatitis (SAH) is high, but there are no effective treatments to improve short-term mortality other than corticosteroids. This study investigated the effects of adding rifaximin to standard treatment in patients with SAH.

Material And Methods: In this randomized controlled open-label trial, patients with SAH (Maddrey's discriminant function≥32) were randomized to the rifaximin or control group.

Topical Application of Nano-Sized Graphene Oxide Cream Ameliorates Acute Skin Inflammation in Mice.

We have previously shown that nano-sized graphene oxide (NGO) displays anti-inflammatory activities against NKT cell-mediated sepsis. To address whether NGO could be applied to treat acute skin inflammation, we developed a conventional skin Cetaphil cream containing NGO (denoted as NGO cream) for topical application to skin lesions and investigated its therapeutic efficacy by employing the tape-stripping-induced acute skin inflammation model. Topical application of NGO cream to the wounded area significantly reduced skin lesions compared with application of the control cream.

Overexpression of Chromatin Remodeling Factor SRG3 Down-Regulates IL1β-Expressing M1 Macrophages and IL17-Producing T Cells in Adipose Tissues.

The SWItch3-related gene (SRG3) is a core component of ATP-dependent SWI/SNF complexes, which are crucial for regulating immune cell development and function (e.g., macrophages and CD4 T cells), embryonic development, and non-immune cell differentiation.

The iNKT cell ligand α-GalCer prevents murine septic shock by inducing IL10-producing iNKT and B cells.

Introduction: α-galactosylceramide (α-GalCer), a prototypical agonist of invariant natural killer T (iNKT) cells, stimulates iNKT cells to produce various cytokines such as IFNγ and IL4. Moreover, repeated α-GalCer treatment can cause protective or pathogenic outcomes in various immune-mediated diseases. However, the precise role of α-GalCer-activated iNKT cells in sepsis development remains unclear.

Alpha-galactosylceramide pre-treatment attenuates clinical symptoms of LPS-induced acute neuroinflammation by converting pathogenic iNKT cells to anti-inflammatory iNKT10 cells in the brain.

Background: Invariant natural killer T (iNKT) cells play protective or pathogenic roles in a variety of immune and inflammatory diseases. However, whether iNKT cells contribute to the progression of acute neuroinflammation remains unclear. Thus, we addressed this question with a mouse model of lipopolysaccharide (LPS)-induced acute neuroinflammation.

A refined prediction model for survival in hepatocellular carcinoma patients treated with transarterial chemoembolization.

Background/aims: Transarterial chemoembolization (TACE) is widely performed as a major treatment for hepatocellular carcinoma (HCC) patients, and there is a need to stratify patients for whom the most benefit from the treatment. This study aimed to develop a refined prediction model for overall survival (OS) in patients undergoing TACE as a first-line treatment in a large cohort and validate its performance.

Methods: A total of 2,632 patients with HCC of Barcelona Clinic Liver Cancer stage A or B who underwent TACE between 2008 and 2017 were enrolled.

Medical treatment of osteoarthritis: botanical pharmacologic aspect.

Osteoarthritis (OA) is the most common form of arthritis, and its prevalence is expected to further increase as our society ages. Despite many approaches to cure OA, no drugs are currently proven to modulate the progression of OA. Nowadays, new OA treatment options are holistically developed and one of the approaches of treatment option is botanical drugs.

Differential liver function at cessation of atezolizumab-bevacizumab versus lenvatinib in HCC: a multicenter, propensity-score matched comparative study.

Background: Atezolizumab+bevacizumab (AB) and lenvatinib have been proposed as first-line treatment options for patients with advanced hepatocellular carcinoma (HCC), but comparative efficacy and associated factors are controversial.

Materials And Methods: This real-world multicenter study analysed patients with HCC who received AB (n=169) or lenvatinib (n=177).

Results: First, 1:1 propensity score matching (PSM) was performed, resulting in 141 patients in both the AB and lenvatinib groups.

Role of CD1d and iNKT cells in regulating intestinal inflammation.

Invariant natural killer T (iNKT) cells, a subset of unconventional T cells that recognize glycolipid antigens in a CD1d-dependent manner, are crucial in regulating diverse immune responses such as autoimmunity. By engaging with CD1d-expressing non-immune cells (such as intestinal epithelial cells and enterochromaffin cells) and immune cells (such as type 3 innate lymphoid cells, B cells, monocytes and macrophages), iNKT cells contribute to the maintenance of immune homeostasis in the intestine. In this review, we discuss the impact of iNKT cells and CD1d in the regulation of intestinal inflammation, examining both cellular and molecular factors with the potential to influence the functions of iNKT cells in inflammatory bowel diseases such as Crohn's disease and ulcerative colitis.

Factors for achieving target serum uric acid levels after initiating urate-lowering therapy in patients with gout: results from the ULTRA registry.

Achieving target serum uric acid (SUA) levels is important in gout management. Guidelines recommend lowering SUA levels to < 6 mg/dL; however, many patients fail to reach this target, even with uric acid-lowering therapy (ULT). This study investigated clinical characteristics of target SUA achievers among Korean patients with gout.

Low liver fat in non-alcoholic steatohepatitis-related significant fibrosis and cirrhosis is associated with hepatocellular carcinoma, decompensation and mortality.
