Evaluation of pathology review at gynaecological oncology multidisciplinary team meetings: a 5-year prospective analysis of cases with major diagnostic discordance.

Multidisciplinary team meetings (MDTs) play an essential role in the management of patients with newly diagnosed and recurrent cancers, and often include review of pathology specimens that were initially assessed in external departments. Many studies have demonstrated a low but significant rate of diagnostic disagreement following such review but the pathological findings have seldom been detailed. We present a prospective 5-year study of all external cases reviewed at the Western Australian Gynaecological Oncology MDT focusing upon those cases with major diagnostic discordance likely to impact patient management.

Suture Dehiscence in the Tricuspid Annulus: An Ex Vivo Analysis of Tissue Strength and Composition.

Background: Surgical repair of functional tricuspid regurgitation (FTR) is an increasingly common practice, but annuloplasty suture dehiscence remains a significant problem. Quantitative and mechanistic understanding of annular suture holding strength can support more effective techniques for tricuspid valve device anchoring.

Methods: Suture holding strength of ovine tricuspid annuli (n = 15) was quantified ex vivo by pullout testing at 12 positions around their circumference.

Novel Method to Track Soft Tissue Deformation by Micro-Computed Tomography: Application to the Mitral Valve.

Increasing availability of micro-computed tomography (µCT) as a structural imaging gold-standard is bringing unprecedented geometric detail to soft tissue modeling. However, the utility of these advances is severely hindered without analogous enhancement to the associated kinematic detail. To this end, labeling and following discrete points on a tissue across various deformation states is a well-established approach.

Bioregulation of kallikrein-related peptidases 6, 10 and 11 by the kinin B₁ receptor in breast cancer cells.

The sera of patients with breast cancer have higher levels of des[Arg(9)]bradykinin, a kinin B1 receptor (B1R) agonist, than that from healthy individuals. Stimulation of breast cancer cells with the analog Lys-des[Arg(9)]bradykinin causes release of metalloproteinases-2 and -9 and increases cell proliferation. We examined the possibility that breast cancer cells, in addition to B1R, express the kinin-forming protease true tissue kallikrein (KLK1) and the endogenous proteins termed kininogens from which kinins are enzymatically released.
