    • To identify knowledge gaps regarding new-onset agitation and impulsivity prior to onsetof cognitive impairment or dementia the International Society to Advance Alzheimer’sResearch and Treatment Neuropsychiatric Syndromes (NPS) Professional InterestAreaconducted a scoping review. Extending a series of reviews exploring the pre-dementiarisk syndrome Mild Behavioral Impairment (MBI), we focused on late-onset agitationand impulsivity (the MBI impulse dyscontrol domain) and risk of incident cognitivedecline and dementia. This scoping review of agitation and impulsivity pre-dementiasyndromes summarizes the current biomedical literature in terms of epidemiology,diagnosis andmeasurement, neurobiology, neuroimaging, biomarkers, course and prognosis,treatment, and ongoing clinical trials. Validations for pre-dementia scales suchas the MBI Checklist, and incorporation into longitudinal and intervention trials, areneeded to better understand impulse dyscontrol as a risk factor for mild cognitiveimpairment and dementia.

  • The genomic landscape of hypodiploid acute lymphoblastic leukemia
  • 2013
  • Ingår i: Nature Genetics. - : Springer Science and Business Media LLC. - 1546-1718 .- 1061-4036. ; 45:3, s. 242-252

    • The genetic basis of hypodiploid acute lymphoblastic leukemia (ALL), a subtype of ALL characterized by aneuploidy and poor outcome, is unknown. Genomic profiling of 124 hypodiploid ALL cases, including whole-genome and exome sequencing of 40 cases, identified two subtypes that differ in the severity of aneuploidy, transcriptional profiles and submicroscopic genetic alterations. Near-haploid ALL with 24-31 chromosomes harbor alterations targeting receptor tyrosine kinase signaling and Ras signaling (71%) and the lymphoid transcription factor gene IKZF3 (encoding AIOLOS; 13%). In contrast, low-hypodiploid ALL with 32-39 chromosomes are characterized by alterations in TP53 (91.2%) that are commonly present in nontumor cells, IKZF2 (encoding HELIOS; 53%) and RB1 (41%). Both near-haploid and low-hypodiploid leukemic cells show activation of Ras-signaling and phosphoinositide 3-kinase (PI3K)-signaling pathways and are sensitive to PI3K inhibitors, indicating that these drugs should be explored as a new therapeutic strategy for this aggressive form of leukemia.
