Curcumin is a polyphenol extracted from the rhizomes of the turmeric plant, Curcuma longa which has anti-inflammatory, and anticancer properties. Chronic inflammation is associated with the development of cancer. Curcumin acts on the regulation of various immune modulators, including cytokines, cyclooxygenase-2 (COX-2), and reactive oxygen species (ROS), which partly explains its anticancer effects. It also takes part in the downregulation of growth factors, protein kinases, oncogenic molecules and various signaling pathways, such as nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB), c-Jun N-terminal kinase (JNK) and signal transducer and activator of transcription 3 (STAT3) signaling. Clinical trials of curcumin have been completed or are ongoing for various types of cancer. This review presents the molecular mechanisms of curcumin in different types of cancer and the evidence from the most recent clinical trials.

Hepatocellular carcinoma (HCC) is the most common primary liver malignancy. It is principally associated with liver cirrhosis and chronic liver disease. The major risk factors for the development of HCC include viral infections (HBV, HCV), alcoholic liver disease (ALD,) and non-alcoholic fatty liver disease (NAFLD). The optimal treatment choice is dictated by multiple variables such as tumor burden, liver function, and patient’s health status. Surgical resection, transplantation, ablation, transarterial chemoembolization (TACE), and systemic therapy are potentially useful treatment strategies. TACE is considered the first-line treatment for patients with intermediate stage HCC. The purpose of this review was to assess the indications, the optimal treatment schedule, the technical factors associated with TACE, and the overall application of TACE as a personalized treatment for HCC.

This study aims to assess the role of Color Duplex Ultrasound with or without contrast media for surveillance following endovascular aortic aneurysm repair (EVAR). A systematic search of the literature published until April 2022 was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The pooled rates of endoleak detection through Contrast-Enhanced or Color Duplex Ultrasound (CEUS or CDUS) and Computed Tomography Angiography (CTA) with 95% confidence intervals (CIs) were estimated using random-effect analysis. Thirty-eight studies were considered eligible for inclusion. The total number of patients in the included studies was 5214 between 1997 and 2021. The overall pooled rate of endoleak detection using CDUS and CTA was 82.59% and 97.22%, while the rates for CEUS and CTA were 96.67% and 92.82%, respectively. The findings of the present study support the use of the CEUS for endoleak detection. However, it should be integrated into institutional protocols for EVAR surveillance to further evaluate its clinical utility in the post-EVAR period before it can be recommended as the sole imaging modality after EVAR.

Primary sclerosing cholangitis (PSC) is a chronic, immune-mediated cholestatic liver disease characterized by progressive bile duct inflammation and fibrosis. Its strong association with inflammatory bowel disease (IBD) highlights the possible role of the gut–liver axis in disease pathogenesis. Here, we review the mechanisms that may contribute to the disruption of the gut–liver axis, leading to liver injury and the development of PSC. In particular, disruption of the intestinal barrier allows microbial products to enter the portal circulation, stimulating hepatic immune cells and triggering biliary inflammation. Concurrently, gut-primed lymphocytes expressing mucosal homing receptors migrate aberrantly to the liver, where they may contribute to biliary epithelial cell injury. Dysbiosis, characterized by reduced microbial diversity and the expansion of bile-tolerant and pro-inflammatory taxa, amplifies this immune activation and disturbs gut–liver homeostasis. Moreover, bile acids act as signaling molecules, regulating metabolism and immune responses through receptors such as FXR and TGR5. Dysregulation of these pathways may promote cholestasis, inflammation, and fibrosis. By understanding these interactions, we may identify novel therapeutic targets for PSC.
