A stimulation protocol that exclusively uses four extrastimuli improves the specificity and efficiency of programmed ventricular stimulation without compromising the yield of monomorphic ventricular tachycardia in patients with coronary artery disease.
INTRODUCTION:
Colorectal cancer (CRC) is a major cause of cancer-related morbidity and mortality in the United States. Although various interventions have improved screening rates, they often require abundant resources and can be difficult to implement. Social psychology and behavioral economics principles offer an opportunity for low-cost and easy-to-implement strategies but are less common in clinical settings.
METHODS:
We randomized 2,000 patients aged 50–75 years eligible for CRC screening to one of the 2 mailed interventions: a previously used text-based letter describing and offering fecal immunochemical testing (FIT) and colonoscopy (usual care arm); or a letter leveraging social psychology and behavioral economics principles (e.g., implied scarcity and choice architecture), minimal text, and multiple images to offer FIT and colonoscopy (intervention arm). We compared total screening uptake, FIT uptake, and colonoscopy uptake at 1-month intervals in each group.
RESULTS:
There were 1,882 patients included in the final analysis. The mean age was 69.3 years, and baseline characteristics in the 2 groups were similar. Screening completion at 26 weeks was 19.5% in the usual care arm (16.3% FIT vs 3.2% colonoscopy, P < 0.01) and 24.1% in the intervention arm (22.1% FIT vs 2.0% colonoscopy, P < 0.01) (P = 0.02).
DISCUSSION:
Among primary care patients aged 50–75 years in an academic setting, mailed CRC outreach employing social psychology and behavioral economics principles led to a higher participation in CRC screening than usual care mailed outreach.
TRANSLATIONAL IMPACT:
Mailed interventions to increase CRC screening should incorporate social psychology and behavioral economics principles to improve participation.
Defibrillation thresholds with monophasic shocks are approximately 30% lower with the distal electrode as the anode. The use of anodal shocks may obviate the need for a subcutaneous patch and allow more frequent implantation of a transvenous lead system.
Severe and frequent GERD symptoms are strongly associated with increased risk of BE in the general population, especially in the absence of frequent PPI use. Among people with GERD, family history of BE and early age of symptom onset were stronger predictors of BE. These findings may improve identification of patients at highest risk for BE.

No prospective studies have compared sotalol and amiodarone during electropharmacologic testing. The purpose of this prospective, randomized study was to compare the electrophysiologic effects of sotalol and amiodarone in patients with coronary artery disease and sustained monomorphic ventricular tachycardia (VT). Patients with coronary artery disease and sustained monomorphic VT inducible by programmed stimulation were randomly assigned to receive either sotalol (n = 17) or amiodarone (n = 17). The sotalol dose was titrated to 240 mg twice daily over 7 days. Amiodarone dosing consisted of 600 mg 3 times daily for 10 days. An electrophysiologic test was performed in the baseline state and at the end of the loading regimen. An adequate response was defined as the inability to induce VT or the ability to induce only relatively slow hemodynamically stable VT. During the follow-up electrophysiologic test, 24% of patients taking sotalol and 41% of those taking amiodarone had an adequate response to therapy (p = 0.30). Amiodarone lengthened the mean VT cycle length to a greater degree than sotalol (28% vs 12%, p < 0.01). There were no significant differences in the effects of sotalol and amiodarone on the ventricular effective refractory period. In patients with coronary artery disease, amiodarone and sotalol are similar in efficacy in the treatment of VT as assessed by electropharmacologic testing. The effects of the 2 drugs on ventricular refractoriness are similar, but amiodarone slows VT to a greater extent than sotalol.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
