Chromosomal and genetic anomalies in fetuses with nuchal translucency between 3.0 and 3.4 mm: A systematic review and meta‐analysis

open access: yesActa Obstetricia et Gynecologica Scandinavica, EarlyView.
Fetuses with a nuchal translucency between 3.0 and 3.4 mm showed a high rate of chromosomal anomalies and copy number variants, most of which could potentially be detected through cell‐free DNA. Abstract Introduction To report the prevalence of chromosomal anomalies in fetuses with a nuchal translucency (NT) between 3.0 and 3.4 mm and to assess the ...

Ibrutinib versus allogeneic haematopoietic stem cell transplant in relapsed/refractory del(17p) chronic lymphocytic leukaemia/small lymphocytic lymphoma

open access: yesBritish Journal of Haematology, EarlyView.
After adjusting for confounders, the ibrutinib cohort had significantly better overall survival (adjusted hazard ratio, 0.39; 95% confidence interval, 0.23–0.68; p = 0.0008) than the allogeneic haematopoietic stem cell transplantation (alloHSCT) cohort.
