Liver Investigation: Testing Marker Utility in Steatohepatitis (LITMUS): Assessment & validation of imaging modality performance across the NAFLD spectrum in a prospectively recruited cohort study (the LITMUS imaging study): Study protocol.

Non-alcoholic fatty liver disease (NAFLD) is the liver manifestation of the metabolic syndrome with global prevalence reaching epidemic levels. Despite the high disease burden in the population only a small proportion of those with NAFLD will develop progressive liver disease, for which there is currently no approved pharmacotherapy. Identifying those who are at risk of progressive NAFLD currently requires a liver biopsy which is problematic.

Cancer screening: global debates and Cuban experience.

A review was conducted of screening strategies for detecting the main cancer sites for which screening has been recommended, assessing WHO and other international organizations' positions, as well as the requirements of Cuba's cancer control strategy. Universally, screening is recommended for cervical, breast and colorectal cancer, all included in the Cuban strategy. Additionally, in Cuba, PSA testing is indicated for men considered at risk (aged >45 years with family history) and those aged >50 years who request it; annual oral exams and teaching of oral self-examination are recommended for the entire population; and for adults aged >35 years, active annual oral cancer case finding.
