Near-Surface Engineered Environmental Barrier Integrity
The INEEL Environmental Systems Research and Analysis (ESRA) program has launched a new R&D project on Near-Surface Engineered Environmental Barrier Integrity to increase knowledge and capabilities for using engineering and ecological components to improve the integrity of near-surface barriers used to confine contaminants from the public and the environment. The knowledge gained and the capabilities built will help verify the adequacy of past remedial decisions and enable improved solutions for future cleanup decisions. The research is planned to (a) improve the knowledge of degradation mechanisms (weathering, biological, geological, chemical, radiological, and catastrophic) in times shorter than service life, (b) improve modeling of barrier degradation dynamics, (c) develop sensor systems to identify degradation prior to failure, and (d) provide a better basis for developing and testing of new barrier systems to increase reliability and reduce the risk of failure. Our project combines selected exploratory studies (benchtop and field scale), coupled effects accelerated aging testing and the meso-scale, testing of new monitoring concepts, and modeling of dynamic systems. The performance of evapo- transpiration, capillary, and grout-based barriers will be examined

HBsAg-negative/anti-HBc-positive patients treated with rituximab: prophylaxis or monitoring to prevent hepatitis B reactivation?
Rituximab (RTX) has been classified as a drug associated with a high risk for hepatitis B virus (HBV) reactivation in HbsAg-negative/anti-HBc-positive patients. However, data on frequency of HBV reactivation are limited especially for RTX monotherapy. Several new recommendations for screening, monitoring and prophylactic antiviral treatment have been published recently. Here, we report the real-life experience in the management and reactivation rate of HbsAg-negative/anti-HBc-positive patients treated with RTX with or without chemotherapy from a large cohort and discuss our results in the light of updated recommendations
