Hepatitis B virus (HBV) reactivation can occur in immunosuppressed patients. Specifically, HBV reactivation after chimeric antigen receptor T-cell (CAR T-cell) therapy is a known complication with few case reports and specific treatment guidelines. Our patient experienced HBV reactivation 27 months after CAR T-cell therapy even with 23 months of entecavir prophylaxis.

In situ closed-cell gas reaction (CCGR) studies performed using (scanning) transmission electron microscopy (STEM) can separate and identify localized dynamic reactions, which are extremely challenging to capture using other characterization techniques. For these experiments, we used a CCGR holder that utilizes microelectromechanical systems (MEMS)-based heating microchips (hereafter referred to as "E-chips").

Common causes of chronic liver disease include alcohol, viral hepatitis, and non-alcoholic steatohepatitis (NASH). Inflammation is a critical driver in the progression of liver disease to liver fibrosis and ultimately cirrhosis.

Methods: In all, 151 infants undergoing cardiac surgery were prospectively enrolled between June 2017 and June 2018 at two centers, one using conventional CPB (2.4 L · min · m, 150 mL · kg · min) with reduction of flow rates with moderate hypothermia and with a targeted hematocrit greater than 25% (center 1, n = 91), and the other using higher bypass flow rates (175 to 200 mL · kg · min) and higher minimum hematocrit (greater than 32%) CPB (center 2, n = 60).
Protocols for conducting in situ transmission electron microscopy (TEM) reactions using an environmental TEM with dry gases have been well established. However, many important reactions that are relevant to catalysis or high-temperature oxidation occur at atmospheric pressure and are influenced by the presence of water vapor. These experiments necessitate using a closed-cell gas reaction TEM holder.
