Transient elastography and diffusion-weighted magnetic resonance imaging for assessment of liver fibrosis in children with chronic hepatitis C.

Background: Chronic hepatitis C (CHC) is a health burden with consequent morbidity and mortality. Liver biopsy is the gold standard for evaluating fibrosis and assessing disease severity and prognostic purposes post-treatment. Noninvasive alternatives for liver biopsy such as transient elastography (TE) and diffusion-weighted magnetic resonance imaging (DW-MRI) are critical needs.

Seronegative autoimmune hepatitis in children : A real diagnostic challenge.

Background And Aim: Classical autoimmune hepatitis (AIH) is characterized by the presence of conventional autoantibodies (anti-smooth muscle, antinuclear and anti-liver-kidney-microsomal antibodies). The absence of such autoantibodies in some patients does not preclude AIH diagnosis or the need for its treatment. This group of patients was termed seronegative AIH.

Methodology for the Accurate Measurement of the Power Dissipated by Braking Rheostats.

The energy efficiency of transportation is a crucial point for the rail and metro system today. The optimized recovery of the energy provided by the electrical braking can lead to savings of about 10% to 30%. Such figures can be reached by infrastructure measures which allow the recovery of the breaking energy that is not directly consumed by the rail system and dissipated in rheostat resistors.

Laboratory Calibration of Energy Measurement Systems (EMS) under AC Distorted Waveforms.

Current standard EN 50463-2 indicates the tests and the requirements to be satisfied for an energy measurement system of a traction unit for railway applications. Some of these tests are to be done with several harmonics superposed on the rated voltage, respectively current. However, no calibration systems satisfying the standard requirements were available few years ago.

Outcomes of Veno-Arterial Extracorporeal Membrane Oxygenation for In-Hospital Cardiac Arrest.

Veno-arterial extracorporeal membrane oxygenation is increasingly used in cardiac arrest. Currently, public registries report the outcomes of cardiac arrest regardless of the setting (out-of-hospital versus in-hospital). Meanwhile, in-hospital cardiac arrest represents a more favorable setting for extracorporeal membrane oxygenation-assisted cardiopulmonary resuscitation than out-of-hospital cardiac arrest.
