Latency to first seizure after temporal lobectomy predicts long-term outcome.

Purpose: Temporal lobectomy is a well-established treatment for refractory temporal lobe epilepsy, yet many patients experience at least one seizure postoperatively. Little is known about the prognostic significance of the time from surgery to first seizure relapse in predicting long-term outcome.

Methods: In a retrospective analysis of patients who reported at least one complex partial seizure (CPS) or generalized tonic–clonic seizure (GTCS) after anterior temporal lobectomy (n = 268), we used a nominal response logistic model to predict the odds ratio (OR) of a seizure outcome based on length of the latency period from surgery to first postoperative seizure.

Heparin stimulates Staphylococcus aureus biofilm formation.

Heparin, known for its anticoagulant activity, is commonly used in catheter locks. Staphylococcus aureus, a versatile human and animal pathogen, is commonly associated with catheter-related bloodstream infections and has evolved a number of mechanisms through which it adheres to biotic and abiotic surfaces. We demonstrate that heparin increased biofilm formation by several S.
