Hepatology is a branch of medicine concerned with the study, prevention, diagnosis and management of diseases that affect the liver, gallbladder, biliary tree and pancreas. The term hepatology is derived from the Greek words “hepatikos” and “logia,” which mean liver and study, respectively. Hepatitis affects millions of individuals globally and is associated with several poor outcomes including liver transplant and liver cancer. In particular, hepatitis B and hepatitis C are major causes of liver cancer, while alcohol abuse has been linked to conditions such as cirrhosis and other serious complications. The conditions hepatologists deal with most frequently are viral hepatitis and alcohol-related liver disease. Hepatology used to be considered a subspecialty of gastroenterology, but nowadays doctors can specialize in hepatology, which is quickly emerging as a freestanding speciality. As a critical organ that can be affected by a large number of factors, the liver is usually the focal point in hepatology. A hepatologist generally only assesses patients after they are referred by their doctor. A hepatologist may also be involved in the follow-up of patients who have received a liver transplant.

This information can be published in our peer reviewed journal with impact factors and are calculated using citations not only from research articles but also review articles (which tend to receive more citations), editorials, letters, meeting abstracts, short communications, and case reports. The inclusion of these publications provides the opportunity for editors and publishers to manipulate the ratio used to calculate the impact factor and try to increase their number rapidly. Impact factor plays a major role for the particular journal. Journal with higher impact factor is considered to be more important than other ones.
