Improving Expeditionary Blood Supply via Type-Specific Whole Blood.

Introduction: Blood is critical to expeditionary casualty care. Currently, low-titer O whole blood is the preferred product, because it serves as a universal blood product, but demand is higher than supply. Type-specific whole blood (TSWB) has the potential to address this shortfall and provide an identical clinical benefit to specific patient populations.

The USCENTCOM Walking Blood Bank Performance Benchmark and Anticipated Benefit of Universal Low Titer Type O Screening.

The walking blood bank (WBB) is a system for emergency blood acquisition from nearby donors if a patient's blood needs exceed the immediate supply. USCENTCOM medical units will perform a walking blood bank if immediate blood requirements exceed the local supply. A benchmark WBB performance time was needed to provide a training goal for military WBB exercises.

In expeditionary environments, the consistent availability of blood for casualty care is imperative yet challenging. Responding to evidence and the specific needs of its expeditionary context, the US Central Command (USCENTCOM) prioritized supplying stored low titer O whole blood (LTOWB) to its units from March, 2023 onward. A strategy was devised to set minimal LTOWB on-hand supply benchmarks, determined by the number of operating beds and point of injury teams.

Enhanced carrier densities in two-dimensional electron gas formed at BaSnO/SrTaOand SrSnO/SrTaOinterfaces.

Two-dimensional electron gases (2DEGs) realized at perovskite oxide interfaces offer great promise for high charge carrier concentrations and low-loss charge transport. BaSnO(BSO) and SrSnO(SSO) are well-known wide bandgap semiconductors for their high mobility due to the Sn--dominated conduction band minimum (CBM).
