, a consumable mushroom, has shown a potential to enhance the production of neuroprotective bioactive metabolites. Traumatic brain injury (TBI) often leads to cognitive, physical, and psychosocial impairments, resulting in neuroinflammation and the loss of cortical neurons. In this research, the effects of mycelium, its derivative erinacine C, along with the underlying mechanisms, were examined in terms of oxidative stress modulation and neurological improvement in a rat model of mild traumatic brain injury (mTBI).

Article Synopsis
  • A retrospective cohort study in Taiwan examined factors related to significant weight gain in hepatitis C patients treated with direct-acting antiviral agents (DAAs) between 2017 and 2020.
  • The study found that younger age, lower baseline BMI, and reductions in fibrosis-4 (FIB-4) scores were linked to greater increases in body mass index (BMI) after DAA treatment.
  • Additionally, the choice of DAA regimen did not impact weight gain outcomes, suggesting the need for further research into the long-term effects and underlying mechanisms of weight changes following treatment.

Background: Antrodin C, a maleimide derivative compound isolated from the ethanol extract of the mycelium of , is an endemic fungus of Taiwan and a potential chemoprotective agent. However, the molecular mechanisms underlying the mode of action of antrodin C on cancer cells, especially in human colorectal cancer (CRC), remain unclear.

Methods: The cell death and ROS of the antrodin-C-treated HCT-116 cells were measured by annexin V-FITC/propidium iodide staining, DCFDA, and Fluo-3 fluorescence staining assays.

The findings regarding changes in renal function in patients with hepatitis C virus (HCV) infection treated with direct-acting antivirals (DAAs) are controversial. This study attempted to identify the factors associated with the large decline in renal function following DAA treatment. This retrospective cohort study included patients treated with DAAs at Chiayi and Yunlin Chang Gung Hospitals, Taiwan, from 1 January 2017 to 31 October 2020.

Article Synopsis
  • This study looked at how a special kind of medicine called direct-acting antivirals (DAA) helps people with hepatitis C virus (HCV) and liver problems called cirrhosis.
  • They found that more people who took the DAA medicine had better health outcomes compared to those who didn't.
  • The results showed that after two years, people who were treated with DAA had a lower chance of developing new problems (like esophageal varices) and their existing problems didn't get worse as quickly.

Article Synopsis
  • Co-infection in gastric cancer patients is linked to poor prognosis and higher tumor mutation burden.
  • Advanced sequencing techniques revealed frequent genetic mutations and amplifications in key cancer-related genes like ERBB2 and PIK3CA.
  • The ERBB2-PIK3-AKT-mTOR pathway is often activated in these cancers, making infection and high mutation burden significant biomarkers for predicting outcomes.

Real-world data on the effectiveness of glecaprevir/pibrentasvir (GLE/PIB) for patients with HCV infection and compensated cirrhosis is limited, especially for the 8-week regimen and in an Asian population. This retrospective study enrolled 159 consecutive patients with HCV and compensated cirrhosis who were treated with GLE/PIB at a single center in Taiwan. Sustained virological response (SVR) and adverse events (AEs) were evaluated.

Background: The serum aminotransferase elevation in metabolic syndrome (MetS) reflected hepatosteatosis, but there is a conflict with the coexistence of viral hepatitis, especially for the hepatitis B virus (HBV). Thus, this study aimed to investigate the relationship between the alanine aminotransferase (ALT)/aspartate aminotransferase (AST) ratio, MetS, and HBV infection in a rural Taiwanese population.

Methods: We conducted a cross-sectional analysis in southern Taiwan between March and December 2019.

Clinical trials showed pangenotypic direct-acting antivirals' (DAAs) excellent efficacy and safety when treating hepatitis C virus (HCV). Two pangenotypic regimens were examined, glecaprevir/pibrentasvir (GLE/PIB) and sofosbuvir/velpatasvir (SOF/VEL), in a real-world Taiwanese setting, including all HCV patients treated with GLE/PIB or SOF/VEL from August 2018 to April 2020. The primary endpoint was sustained virologic response 12 weeks after treatment cessation (SVR12), including adverse events (AEs).

Introduction: Real-world data regarding the impact of hepatic fibrosis on the effectiveness of sofosbuvir/velpatasvir (SOF/VEL) treatment is limited in the Asian population.

Methods: We analyzed data for all 823 patients with hepatitis C virus treated with SOF/VEL from June 2019 to September 2020 at Chang Gung Memorial Hospital in Chiayi, Taiwan. The degree of fibrosis was determined using the fibrosis-4 (FIB-4) index, with advanced fibrosis or cirrhosis defined as a FIB-4 score of > 3.

Background: Pangenotypic direct-acting antiviral agents (DAAs) glecaprevir/pibrentasvir (GLE/PIB) and sofosbuvir/velpatasvir (SOF/VEL) are effective against all hepatitis C virus (HCV) genotype infections. However, data on pangenotypic DAA treatment for mixed genotype HCV infection are sparse.

Methods: This is a retrospective, single site cohort study analyzing all patients with mixed HCV genotype infections treated with GLE/PIB or SOF/VEL from August 2018 to August 2020 in Chiayi Chang Gung Memorial Hospital, Taiwan.

Purpose: The purpose of this study was to identify genes that were epigenetically silenced by STAT3 in gastric cancer.

Methods: MBDcap-Seq and expression microarray were performed to identify genes that were epigenetically silenced in AGS gastric cancer cell lines depleted of STAT3. Cell lines and animal experiments were performed to investigate proliferation and metastasis of miR-193a and YWHAZ in gastric cancer cell lines.

It remains controversial whether entecavir (ETV) and tenofovir disoproxil fumarate (TDF) is associated with different clinical outcomes for chronic hepatitis B (CHB). This study aimed to compare the long-term risk of ETV versus TDF on hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC) in CHB patients from a large multi-institutional database in Taiwan. From 2011 to 2018, a total of 21,222 CHB patients receiving ETV or TDF were screened for eligibility.

Background: The real-world data of glecaprevir/pibrentasvir (GLE/PIB) therapy for patients with chronic hepatitis C virus (HCV) genotype 2 infection remained limited. We aimed to evaluate the possible predictors of virological failure and side effects of GLE/PIB therapy for chronic genotype 2 HCV-infected patients in a real-world setting.

Methods: A total of 326 compensated HCV genotype 2 patients treated with GLE/PIB 12 weeks for cirrhotic patients (n = 56) and 8 weeks for non-cirrhotic patients (n = 270) were enrolled.

Gastric cancer (GC) is among the most treatment-refractory epithelial malignancies. Aberrant activation of Wnt/β-catenin-signaling has been implicated in a variety of human cancers, including gastric cancer. Here we report that the elevated expression of lymphoid enhancer binding factor 1 (Lef1) is associated with the TNM (tumor- node-metastasis) stage of gastric cancer.

Current guidelines recommend antibiotic prophylaxis for all patients with various degrees of cirrhosis and upper gastrointestinal (UGI) bleeding. This study assessed the need for antibiotic prophylaxis in patients with low Child-Pugh scores. We retrospectively screened all patients with cirrhosis who underwent upper endoscopies for UGI bleeding in a referral hospital in Taiwan between 2003 and 2014, from which 913 patients were enrolled after excluding patients with active bacterial infections, recent antibiotic use, early death, and Child-Pugh class C cirrhosis.

Background/aims: Colorectal cancer (CRC) is the third most common type of cancer and the second leading cause of cancer-related deaths worldwide. PRDXs are antioxidant enzymes that play an important role in cell differentiation, proliferation and apoptosis and have diverse functions in malignancy development. However, the mechanism of aberrant overexpression of PRDX6 in CRC remains unclear.

Article Synopsis
  • Oxidants like tert-butylhydroperoxide (t-BHP) are toxic to humans and play a role in liver diseases, making it essential to explore their effects on liver cells.
  • In experiments using liver cell cultures, t-BHP was found to increase cell death and reactive oxygen species production, as well as activate apoptotic pathways and stress responses within the liver cells.
  • The findings suggest that t-BHP's induced liver cell injury and apoptosis are linked to the upregulation of the protein PDIA6, uncovering new insights into how oxidative stress impacts liver health.
