Noninvasive Assessment of Fibrosis Regression after Direct-acting Antiviral Treatment in Hepatitis C Virus Patients.

Background: New direct acting antiviral agent (DAA) therapies are associated with a high sustained virological response rate (SVR) in hepatitis C virus (HCV) patients. The understanding of the impact of SVR on fibrosis stage is limited.

Objectives: To determine the effect of treatment with the DAAs on long-term liver fibrosis stages, as determined by shear-wave elastography (SWE) or FibroTest.

Do psychological factors predict occurrence of influenza-like symptoms in vaccinated elderly residents of a sheltered home?

Objectives: A previously shown relation between psychological factors and the occurrence of flu has not been tested in elderly people, who are at the greatest risk of mortality from flu complications. This study examined whether psychological factors predict the occurrence of influenza-like symptoms (ILS) in elderly residents.

Design: A prospective correlation design was used.
