Insights into the hepatocellular carcinoma patient journey: results of the first global quality of life survey.

AIM: To better understand the hepatocellular carcinoma (HCC) patient journey, we conducted a patient survey across 13 countries. METHODS: The survey included closed- and open-ended questions developed using an iterative process to gather information on demographics, diagnosis and treatment. Patients self-selected or were directed to the online survey by their doctor. RESULTS: A total of 256 patients completed the survey. More than two-thirds (68%) felt they did not receive enough information about HCC at diagnosis. Treatments included oral anticancer therapy, transarterial chemoembolization (TACE), and selective internal radiation therapy (SIRT). A total of 81% receiving sorafenib, 45% receiving SIRT and 32% receiving TACE reported impaired quality-of-life (QoL). A total of 42, 19 and 0% of patients using sorafenib rated their current QoL as 'poor', 'good' and 'excellent', respectively; compared with SIRT (22, 33 and 6%) or TACE (11, 37 and 13%). CONCLUSION: Most patients with HCC require additional accessible information. People with incurable HCC require treatments that preserve QoL.

Endoplasmic reticulum proteostasis in hepatic steatosis.

Hepatic steatosis, the first step in the progression of nonalcoholic fatty liver disease, is characterized by triglyceride accumulation in hepatocytes and is highly prevalent in people with obesity. Although initially asymptomatic, hepatic steatosis is an important risk factor for the development of hepatic insulin resistance and type 2 diabetes mellitus and can also progress to more severe pathologies such as nonalcoholic steatohepatitis, liver fibrosis and cirrhosis; hepatic steatosis has, therefore, received considerable research interest in the past 20 years. The lipid accumulation that defines hepatic steatosis disturbs the function of the endoplasmic reticulum (ER) in hepatocytes, thereby generating chronic ER stress that interferes with normal cellular function. Although ubiquitous stress response mechanisms (namely, ER-associated degradation, unfolded protein response and autophagy) are the main processes for restoring cellular proteostasis, these mechanisms are unable to alleviate ER stress in the context of the fatty liver. Furthermore, ER stress and ER stress responses can promote lipid accumulation in hepatocytes in a counter-productive manner and could, therefore, be the origin of a vicious pathological cycle.

New Polyphenols Identified in Artemisiae abrotani herba Extract.

Artemisia abrotanum L. ("southernwood") belongs to the Artemisia genus and it is used in traditional medicine for the treatment of a variety of illnesses. Scarce data is available on the chemical composition of this medicinal plant, most research being focused on the quantitative and qualitative analyses of its essential oil. Our aim was to investigate the content and profile of polyphenols, flavonoids and hydroxycinnamic derivatives present in the Artemisiae abrotani herba extract. We conducted LC/MS analysis and we screened for 19 polyphenols, flavonoids and hydroxycinnamic derivatives. We determined the total content of these compounds and we screened for antioxidant activity. Most polyphenol acids, hydroxycinnamic derivatives and flavonoids were identified and quantified for the first time in this study. We found an original polyphenol distribution profile with high concentration of sinapic acid, rutin, quercetol, ferulic acid and patuletin. We measured the antioxidant activity, the ethanolic extract presenting a modest radical scavenging activity. The value of this study consists in its novelty as it adds new data on the chemical composition of A. abrotanum L. and it opens novel perspectives for medical and nutritional applications of this plant.
