Long-term nucleos(t)ide analog (NA) therapy has been shown to improve the survival in patients with HBV-related cirrhosis. The aim of this study was to evaluate the clinical outcomes and factors associated with survival in HBV-related cirrhotic patients receiving long-term NA treatment. ⋯ Antiviral therapy improves liver function of HBV-related cirrhotic patients and provides a better chance of curative treatment in those with HCC development. Decompensated cirrhosis is a risk factor for liver-related mortality in this special clinical setting.

For locally advanced head and neck cancers, intra-arterial (IA) chemotherapy is utilized for locoregional control with favorable results. The study aimed to evaluate the surgical outcomes of microsurgical reconstruction in head and neck cancer patients with IA chemotherapy METHODS: This cohort study retrospectively reviewed patients who underwent head and neck microsurgical reconstruction from January 2014 to August 2018. Patients with prior history of chemotherapy were included and categorized into two groups according to history of IA chemotherapy (IA group)/intravenous chemotherapy (IV group). Flap survival was evaluated along with microsurgical revision rates and complications. Recipient vessel specimens were analyzed by histological examination. A 1:1 propensity score matched analysis was performed. ⋯ The study cohort included 45 patients with IA chemotherapy and 201 patients with IV chemotherapy. After propensity score matching, the difference in total flap loss and microsurgical revision rates were nonsignificant between two groups. However, the IA group had significantly higher rates of arterial thrombosis (Odds ratio [OR] 4.98; 95%CI, 1.28-19.38; p = 0.021), wound-related complications (OR 3.30; 95%CI, 1.21-9.02; p = 0.02) and revision surgery within one month (OR 3.73; 95%CI, 1.10-12.64; p = 0.035). Based on histology, IA group vessels showed a higher intima/media ratio than the IV group (0.45 ± 0.06 versus 0.23 ± 0.03, p = 0.02) CONCLUSION: Despite treating local advanced head and neck cancers with good results, IA chemotherapy may cause subsequent deleterious effects on local tissue due to the high concentration of cytotoxic chemotherapeutic agents. Surgeons should be cautious in selection of recipient vessels when performing microvascular reconstruction.

Oral cancer is amongst the most prevalent cancers worldwide with rising incidence. Various attempts have been made to elucidate its pathogenesis, and we sought to examine the function of a ubiquitin E3 ligase that was encoded by STUB1. ⋯ The abnormal downregulation of STUB1 may lessen its suppressive effect on TGM2, which induced the onset or exacerbated the progression of oral cancer. The therapeutic approach to enhance the expression of STUB1 could be a promising direction for cancer therapy.

Pathologic data of non-alcoholic fatty liver disease (NAFLD) was limited and the association between NAFLD and chronic hepatitis B remained unclear in Taiwan. This study aimed to determine the pathological manifestations of NAFLD and the impact of concurrent hepatitis B virus (HBV) infection in a medical center. ⋯ Advanced fibrosis in patients with NAFLD was common in the biopsy series, and was related to aging, hypertension, diabetes mellitus and concurrent HBV infection.
