Background: Although intravenous tranexamic acid is used in cardiac surgery to reduce bleeding and transfusion, topical tranexamic acid results in lower plasma concentrations compared with intravenous tranexamic acid, which may lower the risk of seizures. We aimed to determine whether topical tranexamic acid reduces the risk of in-hospital seizure without increasing the risk of transfusion among cardiac surgery patients.

Methods: We conducted a multicenter, double dummy, blinded, randomized controlled trial of patients recruited by convenience sampling in academic hospitals undergoing cardiac surgery with cardiopulmonary bypass.

Article Synopsis
  • A study conducted at 25 hospitals compared the effectiveness of two antiseptic solutions (iodine povacrylex and chlorhexidine gluconate) in preventing surgical-site infections during extremity fracture surgeries.
  • Results showed that iodine povacrylex led to a lower rate of infections in patients with closed fractures (2.4% vs. 3.3%) but did not show a significant difference for open fractures (6.5% vs. 7.3%).
  • Ultimately, the study concluded that iodine povacrylex is a more effective skin antiseptic for closed extremity fractures, resulting in fewer infections compared to chlorhexidine, though both had similar outcomes for reoperations and adverse events.

May 2020

From the Experimental Vascular Medicine (J.G.S., L.A., J.C.B., M.V., A.K.G., J.K.), Amsterdam Cardiovascular Sciences, Amsterdam UMC, University of Amsterdam, the Netherlands.

Rationale: Patients with elevated levels of lipoprotein(a) [Lp(a)] are hallmarked by increased metabolic activity in the arterial wall on positron emission tomography/computed tomography, indicative of a proinflammatory state.

Objective: We hypothesized that Lp(a) induces endothelial cell inflammation by rewiring endothelial metabolism.

Methods And Results: We evaluated the impact of Lp(a) on the endothelium and describe that Lp(a), through its oxidized phospholipid content, activates arterial endothelial cells, facilitating increased transendothelial migration of monocytes.

Background: Low 25-hydroxyvitamin D is associated with cardiovascular, renal, and infectious risks. Postsurgical patients are susceptible to similar complications, but whether vitamin D deficiency contributes to postoperative complications remains unclear. We tested whether low preoperative vitamin D is associated with cardiovascular events within 30 days after noncardiac surgery.

Attempts to develop a drug treatment for female sexual interest/arousal disorder have so far been guided by the principle of 'one size fits all', and have failed to acknowledge the complexity of female sexuality. Guided by personalized medicine, we designed two on-demand drugs targeting two distinct hypothesized causal mechanisms for this sexual disorder. The objective of this study was to design and test a novel procedure, based on genotyping, that predicts which of the two on-demand drugs will yield a positive treatment response.
