Early engraftment and immune kinetics following allogeneic transplant using a novel reduced-toxicity transplant strategy in children/adolescents with high-risk transfusion-dependent thalassemia: Early results of the ThalFAbS trial.

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.

Chimeric aggregative multicellularity in absence of kin discrimination.

Aggregative multicellularity is a cooperative strategy employed by some microorganisms. Unlike clonal expansion within protected environments during multicellular eukaryotic development, an aggregation strategy introduces the potential for genetic conflicts and exploitation by cheaters, threatening the stability of the social system. , a soil-dwelling bacterium, employs aggregative multicellularity to form multicellular fruiting bodies that produce spores in response to starvation.

Evaluating Multicultural Autism Screening for Toddlers Using Machine Learning on the QCHAT-10.

Early identification and intervention often leads to improved life outcomes for individuals with Autism Spectrum Disorder (ASD). However, traditional diagnostic methods are time-consuming, frequently delaying treatment. This study examines the application of machine learning (ML) techniques to 10-question Quantitative Checklist for Autism in Toddlers (QCHAT-10) datasets, aiming to evaluate the predictive value of questionnaire features and overall accuracy metrics across different cultures.
