Pretransplant MRD detection of fusion transcripts is strongly prognostic in KMT2A-rearranged acute myeloid leukemia.

Pretransplant detection of KMT2Ar measurable residual disease ≥0.001% by quantitative polymerase chain reaction was associated with significantly inferior posttransplant survival (2-year relapse-free survival 17% vs 59%; P = .001) and increased 2-year cumulative incidence of relapse (75% vs 25%, P = .

Pitfalls in Diagnosis: JMML versus Rearranged Juvenile AML.

Background: Lysine methyltransferase 2A () rearrangements are commonly found in juvenile acute myeloid leukaemia (AML). Although distinct diseases, there is a known clinical overlap between -rearranged AML and juvenile myelomonocytic leukaemia (JMML). Both occur in infancy or early childhood and present with abnormal monocytosis.

Motor Milestones: Sensory Motor Trends of Young Children with Classic Galactosemia.

Speech problems affect about 66% of children with classic galactosemia (CG), but little is known about early motor and sensory motor development in this at-risk population (Rubio-Gozalbo et al., 2019). Research has been focused on speech and language development leaving a paucity of data on motor and sensory differences.

Research Priorities for Childhood Apraxia of Speech: A Long View.

This article introduces the Special Issue: Selected Papers From the 2022 Apraxia Kids Research Symposium. The field of childhood apraxia of speech (CAS) has developed significantly in the past 15 years, with key improvements in understanding of basic biology including genetics, neuroscience, and computational modelling; development of diagnostic tools and methods; diversity of evidence-based interventions with increasingly rigorous experimental designs; and understanding of impacts beyond impairment-level measures. Papers in this special issue not only review and synthesize the some of the substantial progress to date but also present novel findings addressing critical research gaps and adding to the overall body of knowledge.

Targeted 8-arm PEG Nanosystems for Localization of Choroidal Neovascularization Macular Degeneration Model.

8-arm PEG (polyethylene-glycol) is a highly promising nanoplatform due to its small size (<10 nm), ease-of-conjugation (many functionalized variants are readily available with "click-like" properties), biocompatibility, and optical inactivity. This study evaluates 8-arm PEG uptake into cells () and localization and clearance in vasculature () for targeting of choroidal neovascularization in mice, an animal model of macular degeneration. 8-arm PEG nanoparticles were labeled with fluorescein isothiocyanate (FITC) and functionalized in the absence or presence of pentameric Ar-Gly-Asp (RGD; 4 RGD motifs and a PGC linker), one of the most common peptide motifs used for active targeting.
