Dual vs Single Cardioversion of Atrial Fibrillation in Patients With Obesity: A Randomized Clinical Trial.

Importance: Atrial fibrillation and obesity are common, and both are increasing in prevalence. Obesity is associated with failure of cardioversion of atrial fibrillation using a standard single set of defibrillator pads, even at high output.

Objective: To compare the efficacy and safety of dual direct-current cardioversion (DCCV) using 2 sets of pads, with each pair simultaneously delivering 200 J, with traditional single 200-J DCCV using 1 set of pads in patients with obesity and atrial fibrillation.

Case report of two siblings with type 2A von Willebrand disease involving a novel mutation within the calcium-binding site of the A2 domain of von Willebrand factor.

: Calcium-binding at the A2 domain protects von Willebrand factor (VWF) from cleavage by a disintegrin and metalloproteinase with thrombospondin motifs (ADAMTS13) and is coordinated by five important residues (p.Asp1596, p.Arg1597, p.

Paclitaxel, carboplatin, and oral etoposide as initial treatment for advanced ovarian carcinoma: a Minnie Pearl Cancer Research Network phase II trial.

Purpose: To evaluate the feasibility and toxicity of the combination of paclitaxel, carboplatin, and etoposide in the first-line treatment of patients with stage III or IV adenocarcinoma of the ovary.

Patients And Methods: Patients entering this trial received paclitaxel 200 mg/m(2), 1 h IV infusion, day 1; carboplatin AUC 6.0 IV, day 1; etoposide 50 mg alternating with 100 mg orally, days 1-10.
