TP53 Mutations are Associated with CD19 Negative Relapse and Inferior Outcomes after Blinatumomab in Adults with ALL.

Despite the success of the CD19xCD3 T cell engager blinatumomab in B-cell acute lymphoblastic leukemia (B-ALL), treatment failure is common and can manifest with antigen loss and extramedullary disease (EMD) relapse. To understand the impact of leukemia genetics on outcomes, we reviewed 267 adult patients with B-ALL treated with blinatumomab and used next generation sequencing to identify molecular alterations. Patients received blinatumomab for relapsed/refractory (R/R) disease (n=150), minimal residual disease (MRD+) (n=88), upfront as induction (n=10), or as consolidation in MRD- state (n=19).

Multiclass Synthetic Accessibility Prediction.

Evaluating synthetic accessibility of molecules is an integral component of the drug discovery process. While the application of machine learning models to predict whether small molecules are easy or hard to synthesize has gained attention recently, predetermined thresholds and data set imbalances present challenges for these binary classification approaches. In this study, we introduce a novel multiclass fold-ensembled classification approach to predict the minimum number of steps needed to synthesize a small molecule.

Quantifying animal social behaviour with ecological field methods.

Field studies of social behaviour are challenging due to the need to record or infer interactions between multiple individuals, often under suboptimal environmental conditions or with potential disturbance by observers. Due to the limited field techniques available, we present a novel method to quantify social behaviours in the field by comparing the counts of individuals caught in traps across multiple locations sampled simultaneously. The distribution of individuals between traps gives the extent of aggregation, and phenotypic data allow for inference of non-random assortment.

Characteristics of children attending an autism specific early learning and care setting prior to and following introduction of the National Disability Insurance Scheme.

Background: The rollout of the National Disability Insurance Scheme (NDIS) has transformed the Australian funding landscape for individuals with disability and their families. This study examined whether the profiles of autistic children and their families accessing an early intervention (EI) setting have changed following its introduction.

Methods: The cognition and behavioural profiles of children funded under the NDIS ( = 58) were compared to children who had received block government funding (= 58).
