Abstract

At a nest site in Northern Italy of females of the weevil-hunting digger wasp Cerceris arenaria L. (Hymenoptera: Crabronidae) the provisioning activity and predator-prey relationship were investigated, in particular their specialization in choice of prey. Females were active from middle of June to end of July, and from 8.00 to 19.00. The wasps made provisioning flights throughout the day, mostly in late morning and early afternoon. Individual wasps generally only hunted for 1 or 2 prey species of all those available, maybe because of their higher abundance. The size of prey, which is positively correlated with that of the female wasps, seems to be the main factor determining choice of prey. The nature of the provisioning flights seems to be related to the size of the prey, being more frequent and shorter for smaller weevils. The correlation between prey and wasp biomass is discussed in relation to the size range of the wasps.

Abstract

Background: This multicenter, prospective study evaluated the determinants of zero-fluoroscopy (ZFL) ablation of supraventricular tachycardias. Methods and Results: Four hundred thirty patients (215 male, 55.4±22.1 years) with indication to electrophysiological study or ablation of supraventricular tachycardias were enrolled. All participating physicians agreed to follow the as low as reasonably achievable policy. A procedure was defined as ZFL when no fluoroscopy was used. The total fluoroscopy time inversely correlated to the number of procedures previously performed by each operator since study start ( r =−0.112; P =0.02). Two hundred eighty-nine procedures (67.2%) were ZFL; multivariable analysis identified as predictors of ZFL: procedure after the 30th for each operator, compared with procedures up to the ninth ( P =0.011; hazard ratio, 3.49; 95% confidence interval [CI], 1.79–6.80); the type of arrhythmia ( P =0.031; electrophysiological study and atrioventricular nodal reentry tachycardia ablation having the highest probability of ZFL; hazard ratio, 6.87; 95% CI, 2.08–22.7 and hazard ratio, 2.02; 95% CI, 1.04–3.91, respectively); the operator’s ( P =0.002) and patient’s age ( P =0.009). Among operators, achievement of ZFL varied from 0% to 100%; 8 (22.8%) operators achieved ZFL in 75% of their procedures. The probability of ZFL increased by 2.8% (hazard ratio, 0.98; 95% CI, 0.97–0.99) as patient’s age decreased by 1 year. Acute procedural success was obtained in all cases. Conclusions: The use of 3-dimensional mapping system completely avoided the use of fluoroscopy in most cases, with very low fluoroscopy time in the remaining and high safety and effectiveness profiles. Achievement of ZFL was predicted by the type of arrhythmia, operator’s experience, and patient’s age.

Abstract

A variable proportion, up to 30%, of patients who undergo cardiac resynchronization therapy (CRT) do not benefit from treatment. The aim of the Cardiac Resynchronization Therapy MOdular REgistry (CRT MORE) is to determine whether specific electrocardiographic and radiographic parameters can be used to predict clinical and echocardiographic response to CRT.The CRT MORE is a prospective, single-arm, multicenter cohort study designed to evaluate the electrocardiographic and radiographic predictors of response to CRT. All study patients receive a pacemaker or implantable defibrillator for CRT delivery in accordance with current guidelines. Enrollment started in December 2011 and is scheduled to end in November 2013. Approximately 1100 consecutive patients will be enrolled in 30 Italian centers and will be followed up for 60 months after implantation. The primary endpoint is the improvement in clinical (Clinical Composite Score) and echocardiographic (a decrease of ≥ 15% in left ventricular end-systolic volume) parameters at the 6-month follow-up visit.This study might provide important information about which electrocardiographic and radiographic parameters better predict CRT response.

Abstract

Background: Cryoballoon ablation (CBA) (Arctic Front, Medtronic, USA) has proven very effective in achieving pulmonary vein isolation (PVI). Different transseptal (TS) puncture sites might influence CBA procedure. The aim of the present study was to analyze the influence of different TS puncture sites (anterior, medial and posterior) on the acute and midterm outcomes of CBA in a series of patients undergoing PVI for drug resistant AF. Methods and results: A total 103 patients (78 males, mean age: 57 +/- 13 years) formed the study group. Transseptal punctures were performed in the anterior, medial and posterior portion of the FO in 41 (39.8%), 35 (34%) and 27 (26.2%) patients respectively. We found no statistical significant difference between the various sites of TS puncture in 1) the grade of PV occlusion (p = ns), the rate of PV isolation (p = ns), freedom from AF at a mean 12 month follow-up (p = ns) and complication rates (p = ns). Mean grade of occlusion was slightly lower in the RIPV when puncturing in the posterior FO but did not reach statistical significance. Mean procedural and fluoroscopy times were significantly lower when using the inner lumen mapping catheter (ILMC) (Achieve, Medtronic, USA) than the circular mapping catheter (CMC) (Lasso, Biosense Webster, California, USA) (107.24 mn vs 97.74 (p
