How to avoid patient harm from a magnesium bolus dose.
This paper describes a tracking method that we have developed in order to track a barium bolus in radiological images sequences. Our method combines both region tracking by the means of a deformable region model, and contour tracking by the means of active contours. It allows the tracking of a barium bolus during its descent along the oesophagus and the lower oesophageal sphincter. Thus, we are...
background: this study aimed to compare intermittent intravenous (iv) pantoprazole and ranitidine for control of gastric acid secretion and the possible prevention of upper gastrointestinal bleeding (ugib) in critical care patients. methods: this was a randomized, double blind clinical trial study of iv pantoprazole (40 mg every12 hour) or intermittent iv ranitidine (50 mg bolus every 8 hour) i...
Suday, Sptem er 5, 2016 MethodS and MaterialS: Sprague Dawley rats were injected subcutaneously with two HA fillers, VYC20L [20 mg/mL] or HYC-24L+ [24 mg/mL], to create a projecting bolus. Four days post-injection, recombinant human hyaluronidase (HX) or ovine hyaluronidase (VIT) were administered at varying dose levels (5U/0.1mL bolus, 10U/0.1mL bolus, and 30U/0.1mL bolus). 3D images were capt...
Acute Coronary Syndromes TIMI 14 (Final Results) Presenter: Elliott Antman, MD, Brigham and Women’s Hospital and Harvard Medical School, Boston, Mass. The study: A prospective, multicenter, randomized, controlled trial of combined therapy with thrombolytic agents and the platelet glycoprotein IIb/IIIa antagonist abciximab in patients with AMI. A total of 681 patients were randomized to standard...
BACKGROUND Pharmacodynamics of eptifibatide, a cyclic heptapeptide antagonist of platelet glycoprotein IIb/IIIa, are substantially altered by anticoagulants that chelate calcium, resulting in overestimation ex vivo of the in vivo effects of this agent. We conducted a dose-ranging study to characterize the pharmacodynamics and pharmacokinetics of eptifibatide under physiological conditions. ME...
Special attention is required in planning and administering radiation therapy to patients with cardiac implantable electronic devices (CIEDs), such as pacemaker and defibrillator. The range of dose to CIEDs that can induce malfunction is large among CIEDs. Clinically significant defects have been reported at dose as low as 0.15 Gy. Therefore, accurate estimation of dose to CIED and dose reducti...
