Screening frequency, incidence and pattern of heparin-induced thrombocytopenia syndrome at a large tertiary institution.

Increasing awareness and availability of tests for anti-PF4/heparin complex antibodies has raised concerns about indiscriminate testing and inappropriate diagnosis of heparin-induced thrombocytopenia. A retrospective review of HITS testing at a large tertiary centre was performed to determine test patterns and incidence of HITS. Records of anti-PF4 tests over 4 years were reviewed.

A common BIM deletion polymorphism mediates intrinsic resistance and inferior responses to tyrosine kinase inhibitors in cancer.

Tyrosine kinase inhibitors (TKIs) elicit high response rates among individuals with kinase-driven malignancies, including chronic myeloid leukemia (CML) and epidermal growth factor receptor-mutated non-small-cell lung cancer (EGFR NSCLC). However, the extent and duration of these responses are heterogeneous, suggesting the existence of genetic modifiers affecting an individual's response to TKIs. Using paired-end DNA sequencing, we discovered a common intronic deletion polymorphism in the gene encoding BCL2-like 11 (BIM).
