Creating a Unified Digital Communication Strategy with Chicago Farmers Market Collective
CMFC is a group of independent farmers markets throughout Chicago that work together to get fresh produce to consumers. They need a way to digitally market their company so the message can be clearly advertised to their target market and beyond

Ventricular arrhythmias in super-responders to cardiac resynchronization therapy
La terapia de resincronizaci贸n cardiaca se asocia a mejora de la calidad de vida y reducci贸n de la morbimortalidad de los pacientes con disfunci贸n ventricular grave y QRS ancho. Sobre su papel en la reducci贸n de arritmias ventriculares, hay m谩s discusi贸n. Se compar贸 la incidencia de arritmias ventriculares en pacientes portadores de desfibrilador autom谩tico implantable con funci贸n de resincronizaci贸n cardiaca, seg煤n el grado de respuesta ecocardiogr谩fica a la resincronizaci贸n. Se clasific贸 a los pacientes en tres subgrupos: superrespondedores, respondedores y no respondedores. Se incluy贸 a 196 pacientes seguidos durante una mediana de 30,1 [intervalo intercuart铆lico, 18,0-55,1] meses. Se document贸 presencia de arritmias ventriculares en 37 pacientes (18,8%); 3 pacientes (5,9%) del grupo de superrespondedores presentaron arritmias ventriculares, en comparaci贸n con 14 (22,2%) del grupo de respondedores y 20 (24,4%) del grupo de no respondedores (p = 0,025). En el an谩lisis multivariable, el implante del dispositivo en prevenci贸n secundaria (odds ratio = 4,04; intervalo de confianza del 95%, 1,52-10,75; p = 0,005), la ausencia de superrespuesta ecocardiogr谩fica (odds ratio = 3,81; intervalo de confianza del 95%, 1,04-13,93; p = 0,043), un QRS > 160 ms (odds ratio = 2,39; intervalo de confianza del 95%, 1,00-1,35; p = 0,049) y el tratamiento con amiodarona (odds ratio = 2,47; intervalo de confianza del 95%, 1,03-5,91; p = 0,041) fueron los 煤nicos predictores independientes de aparici贸n de arritmias ventriculares. Los pacientes superrespondedores a la terapia de resincronizaci贸n cardiaca presentan una disminuci贸n significativa en la incidencia de arritmias ventriculares respecto a los dem谩s pacientes. Pese a ello, los episodios arr铆tmicos no llegan a desaparecer por completo en este subgrupo.Cardiac resynchronization therapy is associated with improved quality of life and reduced morbidity and mortality in patients with severe ventricular dysfunction and wide QRS. However, its role in the reduction of ventricular arrhythmias is more controversial. We compared the incidence of ventricular arrhythmias in patients who were undergoing cardiac resynchronization therapy with an implantable cardioverter-defibrillator in terms of the degree of echocardiographic response to resynchronization. Patients were classified in 3 subgroups; super-responders, responders, and nonresponders. We included 196 patients who were followed up for a median 30.1 months [interquartile range, 18.0-55.1 months]. We recorded the presence of ventricular arrhythmias in 37 patients (18.8%); 3 patients (5.9%) in the super-responder group had ventricular arrhythmias vs 14 (22.2%) among the responders and 20 (24.4%) in the group of nonresponders (P = .025). In multivariate analysis, the only independent predictors of the appearance of ventricular arrhythmias were secondary鈥損revention device implantation (odds ratio = 4.04; 95% confidence interval, 1.52-10.75; P = .005), absence of echocardiographic super-response (odds ratio = 3.81; 95% confidence interval, 1.04-13.93; P = 043), QRS >160 ms (odds ratio = 2.39; 95% confidence interval, 1.00-1.35; P = .049) and treatment with amiodarone (odds ratio = 2.47; 95% confidence interval, 1.03-5.91; P = .041). The patients classified as super-responders to cardiac resynchronization therapy had a significant reduction in incidence of ventricular arrhythmias by comparison with the other patients. Despite this, arrhythmic episodes do not completely disappear in this subgroup.Sin financiaci贸n3.792 JCR (2014) Q2. 33/123 Cardiac and cardiovascular systemsUE
