The des-Arg-bradykinin/B1R axis: Hepatic damage in COVID-19.

Patients infected by the SARS-CoV-2 virus are commonly diagnosed with threatening liver conditions associated with drug-induced therapies and systemic viral action. RNA-Seq data from cells in bronchoalveolar lavage fluid from COVID-19 patients have pointed out dysregulation of kallikrein-kinin and renin-angiotensin systems as a possible mechanism that triggers multi-organ damage away from the leading site of virus infection. Therefore, we measured the plasma concentration of biologically active peptides from the kallikrein-kinin system, bradykinin and des-Arg-bradykinin, and liver expression of its proinflammatory axis, bradykinin 1 receptor (B1R).

Total laparoscopic hysterectomy with and without lymph node dissection for uterine neoplasia.

Study Objective: To compare surgical outcomes of patients with uterine neoplasia undergoing total laparoscopic hysterectomy only (TLH) with those having TLH and lymph node dissection (TLHND) from September 5, 1996 through January 13, 2007.

Design: Retrospective chart analysis (Canadian Task Force classification II-2).

Setting: Three tertiary surgical centers in California.
