Autoimmune hepatitis (AIH), primary biliary cirrhosis (PBC) and primary sclerosing cholangitis (PSC) result from the interaction between genetic and environmental factors, but greatly differ in clinical phenotype and target of autoimmune injury. In AIH the autoimmune damage attacks the hepatocytes, leading to a clinically evident hepatitis. The aim of treatment in AIH is to obtain complete remission and to prevent further progression; the backbone of treatment is immunosuppressive therapy, including steroids, required in the long term for the majority of patients. Unfortunately, there is no curative treatment for AIH, and a significant number of patients eventually progress to end-stage liver including liver transplantation (LT).

However, the role of CA9 in the molecular mechanisms of tongue squamous cell carcinoma (TSCC) pathogenesis remains unclear. CA9 expression was analysed using the TCGA database, and its influence on survival was performed using Kaplan-Meier, LASSO and COX regression analyses. The correlation between CA9 and immune infiltration was investigated by CIBERSORT and ESTIMATE. Moreover, the relationship between CA9 expression and downstream molecular regulation pathways was analysed by GSEA, GO and WGCNA. CA9 expression correlated with clinical prognosis and tumour grade in TSCC. Moreover, CA9 expression potentially contributes to the regulation of cancer cell differentiation and mediates tumour-associated genes and signalling pathways, including apoptosis, hypoxia, G2M checkpoint, PI3K/AKR/mTOR signalling and TGF-beta signalling pathways. However, the follicular helper T cells, regulatory T cells, immune and stromal scores showed no significance between high and low CA9 expression groups. These findings suggested that CA9 plays a critical role of TSCC prognosis and tumour grade. CA9 expression significantly correlated with the regulation of cell differentiation, various oncogenes and cancer-associated pathways. © 2020 Department of Oral and Maxillofacial Surgery, Guanghua School of Stomatology, Hospital of Stomatology, Sun Yat-sen University.

BACKGROUND BeGraft Aortic stent (Bentley InnoMed, Hechingen, Germany) allows large postdilation diameter up to 30 mm. With availability of lengths of 19-59 mm and lower stent profile, they can be used in native and recurrent CoA in adults and in pediatric patients. MATERIALS AND METHODS This is a multicentre retrospective analysis of 12 implanted BeGraft Aortic stents in CoA between May 2017 and April 2019. RESULTS Twelve patients aged 7.7-38 years (median 18.3 years) with body weight of 19.9-56 kg (median 45.5 kg). Eight patients (66%) had native juxtaductal CoA while four had recurrent CoA after previous surgical or transcatheter treatments. The stents were implanted successfully in all the patients with no serious adverse events. The length of the stents ranged from 27 to 59 mm and the implanted stent diameter varied from 12 to 18 mm. The median intraprocedural CoA pressure gradient decreased from 25 mmHg (range 16-66 mmHg) to 2 mmHg (range 0-13 mmHg). The mean follow-up duration was 10.2 months. Two patient (16.6%) had residual stent narrowing requiring staged redilation. One patient (8%) had pseudoaneurysm formation at 1 year cardiac CT follow-up. CONCLUSIONS The BeGraft Aortic stent may be considered to be safe and effective in the short term in treatment of CoA from childhood to adulthood. Long-term follow-up is needed. © 2020 Wiley Periodicals, Inc.BACKGROUND Detection of severe renal impairment in patients with venous thromboembolism (VTE) is mandatory both for selecting anticoagulant therapy and for evaluating major bleeding risk, increased by severe renal impairment. OBJECTIVES To determine whether the Cockcroft and Gault (CG) and Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formulas identify severe renal impairment in the same VTE patients presenting the same risk of major bleeding. PATIENTS/METHODS We compared clinical characteristics and outcomes during the first 3 months of anticoagulation between VTE patients in the RIETE registry with severe renal impairment according to the CG and/or CKD-EPI formula (estimated glomerular filtration rate (eGFR) 30). CONCLUSION The CG and CKD-EPI formulas identify different subgroups of patients with severe renal impairment, leading to discordant results in 40.7% of these patients. Irrespective of the formula used for their identification, patients with severe renal impairment have a higher risk of major bleeding under anticoagulant therapy.

They have dramatically changed the strategy of diabetes treatments and also re-iterated the significance of glucagon and α-cells in the pathophysiology of diabetes. First, glucagon and α-cells have been extensively studied in the field of basic medical research. For example, our previous studies has provided molecular evidence for the role of insulin signaling in α-cells in the regulation of glucagon secretion and its involvement in the excessive secretion of glucagon in hyperglycemic state.

Increased adiposity may undermine the pulmonary microenvironment wherein viral pathogenesis and immune cell trafficking could contribute to a maladaptive cycle of local inflammation and secondary injury. A further challenge to those with obesity during the current pandemic may involve vitamin D deficiency/insufficiency. In the interest of personal and public health, we caution decision/policy makers alike not to pin all hope on a proverbial 'silver bullet.' Until further breakthroughs emerge, we should remember that modifiable lifestyle factors like diet and physical activity should not be marginalized. Decades of empirical evidence supports both as key factors promoting health and wellness.
