Non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH) are increasingly a cause of cirrhosis hepatocellular carcinoma globally. This burden is expected to increase as epidemics obesity, diabetes metabolic syndrome continue grow. The goal this analysis was use Markov model forecast NAFLD using currently available data.A used estimate NASH progression in eight countries based on data for adult prevalence obesity type 2 mellitus (DM). Published estimates expert...

Many areas region are experiencing epidemics metabolic syndrome among rapidly ageing populations. Aims To estimate using modelling growth NAFLD populations, including cases with significant fibrosis that most likely to experience advanced related mortality.

The 2016 World Health Assembly endorsed the elimination of hepatitis B virus (HBV) infections by 2030. However, HBV prevalence in Western countries, where historical is low and highly impacted immigration trends, remains uncertain making planning difficult. We aimed to develop a more accurate estimate identify key immigrant populations that need be screened, vaccinated, treated achieve targets.US data from 1900 forward country-specific modeled age sex were used immigrated entering US, new...

Chronic hepatitis B virus (HBV) infection is a leading cause of liver disease and related mortality globally. However, most the infected individuals in United States remain undiagnosed untreated. There need to understand more completely economic burden impact removing treatment restrictions increasing diagnosis treatment. The PRoGReSs model, dynamic HBV model that tracks population by year, stage, gender, was used quantify chronic from 2020 2050 based on four scenarios: status quo (base)...

Summary Due to the introduction of newer, more efficacious treatment options, there is a pressing need for policy makers and public health officials develop or adapt national hepatitis C virus ( HCV ) control strategies changing epidemiological landscape. To do so, detailed, country‐specific data are needed characterize burden chronic infection. In this study 17 countries, literature review published unpublished on prevalence, viraemia, genotype, age gender distribution, liver transplants...

88 Background: There are an estimated 60 million individuals in the US who not up-to-date with average-risk colorectal cancer (CRC) screening, as screening rates and adherence have remained stubbornly below national target of 80%. Efforts ongoing to improve CRC performance participation, including development new blood-based tests. Despite high expectations for these tests, remains lower than other guideline-recommended strategies, particularly respect advanced precancerous lesion (APL)...

The Centers for Medicare &amp; Medicaid Services (CMS) have established criteria covering new blood-based CRC tests if minimum sensitivity specificity thresholds met. However, current challenged by their relative inability detect advanced precancerous lesions (APLs). At present, importance APL versus on...
