What is he best known for?

The fields of study he is best known for:

  • Internal medicine
  • Cancer
  • Surgery

George N. Ioannou mostly deals with Internal medicine, Endocrinology, Gastroenterology, Cirrhosis and Nonalcoholic fatty liver disease. His research on Internal medicine frequently links to adjacent areas such as National Health and Nutrition Examination Survey. His Endocrinology study incorporates themes from Nephrology and Steatohepatitis.

In his research on the topic of Gastroenterology, Iron deficiency, Anemia, Iron-deficiency anemia, Alcohol consumption and Alcohol is strongly related with Odds ratio. His Nonalcoholic fatty liver disease research is multidisciplinary, relying on both Autoimmune hepatitis, Primary sclerosing cholangitis and Lipotoxicity. His Hepatocellular carcinoma study which covers Immunology that intersects with Liver cancer and Veterans Affairs.

His most cited work include:

  • Circulating microRNAs in patients with chronic hepatitis C and non-alcoholic fatty liver disease. (412 citations)
  • NLRP3 inflammasome blockade reduces liver inflammation and fibrosis in experimental NASH in mice. (298 citations)
  • Predictors of colorectal cancer screening participation in the United States. (254 citations)

What are the main themes of his work throughout his whole career to date?

Internal medicine, Cirrhosis, Gastroenterology, Hepatocellular carcinoma and Hepatitis C are his primary areas of study. The concepts of his Internal medicine study are interwoven with issues in Endocrinology and Oncology. As a part of the same scientific study, George N. Ioannou usually deals with the Cirrhosis, concentrating on Model for End-Stage Liver Disease and frequently concerns with Intensive care medicine.

His Gastroenterology research integrates issues from Surgery, Transplantation, National Health and Nutrition Examination Survey and Iron-deficiency anemia. His Hepatocellular carcinoma research includes themes of Liver transplantation and Hepatitis C virus. George N. Ioannou combines subjects such as Ledipasvir and Sofosbuvir with his study of Hepatitis C.

In recent papers he was focusing on the following fields of study:

His primary areas of study are Internal medicine, Cirrhosis, Hepatocellular carcinoma, Oncology and Veterans Affairs. His studies examine the connections between Internal medicine and genetics, as well as such issues in Gastroenterology, with regards to Nightmare. His Cirrhosis research incorporates elements of Liver disease, Model for End-Stage Liver Disease, Intensive care medicine and Receiver operating characteristic.

His biological study deals with issues like Hepatitis C virus, which deal with fields such as Interferon and Hepatitis B virus. His work carried out in the field of Oncology brings together such families of science as Chronic hepatitis, Antiviral treatment and Virologic response. In his work, Dialysis, Intensive care unit and Azithromycin is strongly intertwined with Mechanical ventilation, which is a subfield of Veterans Affairs.

In his most recent research, the most cited papers focused on:

  • Internal medicine
  • Cancer
  • Surgery

His primary areas of investigation include Internal medicine, Cirrhosis, Hepatocellular carcinoma, Hazard ratio and Liver disease. Veterans Affairs, Hepatitis C, Incidence, Abdominal surgery and Retrospective cohort study are the core of his Internal medicine study. His Cirrhosis study is related to the wider topic of Gastroenterology.

His Hepatocellular carcinoma study combines topics in areas such as Antiviral therapy, Direct acting, Oncology and Hepatitis C virus. His research investigates the connection between Hazard ratio and topics such as Cohort study that intersect with issues in Cause of death, Comorbidity, Rate ratio and Radiation therapy. The Liver disease study combines topics in areas such as Odds ratio, Ascites, Chronic liver disease, Blood transfusion and Elective surgery.
