Accurate human action recognition is becoming increasingly important across various fields, including healthcare and self-driving cars. A simple approach to enhance model performance is incorporating additional data modalities, such as depth frames, point clouds, and skeleton information, while previous studies have predominantly used late fusion techniques to combine these modalities, our research introduces a multi-level fusion approach that combines information at early, intermediate, and late stages together. Furthermore, recognizing the challenges of collecting multiple data types in real-world applications, our approach seeks to exploit multimodal techniques while relying solely on RGB frames as the single data source.

Background: Allogeneic transplant for patients with transfusion-dependent thalassemia is challenging once there has been iron overload and chronic transfusion support.

Objective(s): A transplant strategy that reduced intensity of the preparative regimen and tailored immunosuppression to both support donor engraftment and prevent GVHD was developed for this population. The combination of a pretransplant immunosuppression phase with reduced dosing of fludarabine/prednisone, treosulfan-based preparative regimen with reduced cyclophosphamide dosing, and introduction of a calcineurin/methotrexate-free GVHD prophylaxis/engraftment supporting regimen with abatacept/sirolimus/ATG was tested.
