Alcohol dependence in public policy: towards its (re)inclusion

Public policy on alcohol in the UK relies on health promotion campaigns that encourage individuals who misuse alcohol to make healthier choices about their drinking. Individuals with alcohol-dependence syndrome have an impaired capacity to choose health. As a result, individuals with the worst alcohol misuse problems lie largely outside the reach of choice-based policy. However, such policy has been widely criticized and efforts to reform it are underway. This paper argues that the British Medical Association’s recent attempt to improve policy on alcohol in the UK by introducing strategies which have been shown to control drinking within populations still gives insufficient attention to alcohol dependence. This is because it fails accurately and consistently to characterize alcohol dependence and gives insufficient attention to the social challenges it presents

Expression of ezrin is associated with invasion and dedifferentiation of hepatitis B related hepatocellular carcinoma

<p>Abstract</p> <p>Background</p> <p>Hepatocellular carcinoma (HCC) is the fifth most common malignancy in the world and constitutes the leading cause of cancer-related death among men, and second among women in Taiwan. Liver cirrhosis and HCC are relatively prevalent, and 80% to 85% of the patients with these conditions have positive results for hepatitis B surface antigen in Taiwan. Only 5% of the general population is seronegative for all hepatititis B virus (HBV) markers. This is the first study to determine the role of ezrin upon HBV HCC cell and patients with HBV HCC undergoing hepatectomy</p> <p>Methods</p> <p>Immunohistochemical study with ezrin in 104 human HBV-HCC cases were carried out to investigate its association with the clinicopathological features and the outcomes of 104 HBV-HCC patients undergoing hepatetomy. In addition, DNA constructs including the wild type ezrin (wt-ezrin) and mutant ezrin Tyr353 (Y353) were transfected into Hep3B cell to study its role in tumor invasion and differentiation.</p> <p>Results</p> <p>HBV HCC patients with ezrin over-expression independently have smaller tumor size, cirrhotic liver background, poor tumor differentiation, and more vascular invasion. Ezrin expression status has no impact on survival for HBV-HCC patients undergoing hepatectomy. The in vitro assay showed that wt-ezrin Hep3B cells have a significant higher level of AFP secretion and higher invasion ability as compared with the control and Y353- ezrin Hep3B cells.</p> <p>Conclusion</p> <p>Ezrin over-expression contributed to de-differentiation and invasion of HBV-HCC cell. HBV-HCC patients with ezrin over-expression were independently associated with tumor with smaller size, cirrhotic liver background, poor differentiation, and vascular invasion.</p
