ICD with resynchronization therapy can provide information on the intrathoracic fluid status of the pts by measuring transpulmonary electric bioimpedance, Out of 2185 consecutive pts undergoing catheter ablation for AF with an open irrigated catheter, 132 (6p) had heart failure (HF). CRT-D

BACKGROUND:Remote magnetic navigation (RMN) has been reported as a feasible and safe mapping and ablation system for treatment of ventricular arrhythmias (VAs). However, the reported success rates have been limited with the 4- and 8-mm catheter tips.OBJECTIVE:This study sought to report the results in a large series of consecutive patients undergoing radiofrequency (RF) catheter ablation of VAs using the RMN with the 3.5-mm magnetic open-irrigated-tip catheter (OIC).METHODS:A total of 110 consecutive patients with a clinical history of left VA were included in the study. In all cases, an OIC was utilized for mapping and ablation. When ablation with the RMN catheters failed, a manual OIC was used to eliminate the VA. Postablation pacing maneuvers and isoproterenol were used to verify the inducibility of the VAs. Outcomes were compared with those of a group of 92 consecutive patients undergoing manual ablation by the same operator.RESULTS:Mapping and ablation with the magnetic OIC were performed in all 110 patients with VA. Ischemic cardiomyopathy was present in 33 (30%), nonischemic in 14 (13%), and in 63 (57%) patients no structural heart disease was present. Endocardial mapping was performed in all patients, whereas both endocardial and epicardial mapping were performed in 36 (33%) patients. Compared with manual ablation, RMN was associated with a longer procedural time (2.9 +/- 1.2 hours vs. 3.3 +/- 1.1 hours, P = 0.004) and RF time (24 +/- 12 minutes vs. 33 +/- 18 minutes, P = 0.005), whereas fluoroscopic time was significantly shorter (35 +/- 22 minutes vs. 26 +/- 14 minutes, P = 0.033). During the procedures, crossover to manual ablation was required in 15 patients (14%). At 11.7 +/- 2.1 months of follow-up in the study group and 18.7 +/- 3.7 months in the manual ablation group, 85% and 86% (P = 0.817) of patients, respectively, were free of VA.CONCLUSION:This large series of consecutive patients demonstrates that OIC ablation using RMN is effective for the treatment of left VAs.

Each building will continue to be inspected every six months, and any damaged asbestoscontaining materials will be repaired or removed in accordance with AHERA Guidelines. In addition, AHERA also requires each school district to completely survey all buildings within their jurisdiction and update all asbestos management plans on a three-year schedule. The last three-year inspection was completed in June, 2010.

An instructional package consisting of preinstruction and natural environment teaching techniques was used to teach a young man with cerebral palsy and moderate mental retardation to functionally use a simple customized overlay on a Touch Talker. Within the context of a multiple baseline design, the training was introduced in three different school settings during a vocational training task to teach generalized use in functional settings. Sequential withdrawal of the preinstruction was phased into the program for response maintenance. The student's use of the Touch Talker to communicate increased substantially after the introduction of the instructional package in each setting. High levels of device use were maintained as the preinstruction procedures were withdrawn. The implications of these results and observations from the staff working with the student are discussed.

Patterns of marriage between Protestants and Roman Catholics in Switzerland during 1969–72 and 1979–82 are investigated using magnitudes of marriage attraction, measures that reflect the propensity to marry independent of population composition. The results show high levels of intermarriage, with religious differences becoming less salient in marriage choice. There is no evidence that the propensity to intermarry is influenced by ‘minority group’ effects.

SENCAR mice have been selectively bred for hypersusceptibility to 2-stage chemical skin carcinogenesis. In this study the relative susceptibilities of SENCAR, BALB/c and CD-1 mice to systemic carcinogenesis by N-nitrosohexamethyleneimine (NHEX) were examined. NHEX was administered twice weekly (1 mg/mouse) in corn oil by gavage for 30 weeks. NHEX caused primarily liver and lung tumors in all 3 strains of mice. Hemangiosarcomas (but not other liver tumors) were more common in CD-1 mice than BALB/c or SENCAR mice. Lung tumors (adenomas and adenocarcinomas) and forestomach tumors (squamous carcinomas) were more common in SENCAR mice than BALB/c or CD-1 mice. Survival was better in SENCAR mice dosed with NHEX than in the other 2 strains. These results indicate that SENCAR mice are not unusually sensitive to liver carcinogenesis by NHEX, but are relatively sensitive to tumorigenesis in 2 epithelial tissues, lung and forestomach.

Entrapping conflicts are those in which individuals continue to invest their resources—even in seemingly losing propositions-in large part to justify previous unfilled expenditures. It has been demonstrated that individuals define their motivation for investing very differently at the various stages of an entrapping conflict. One implication of this motivational dynamic is that various factors may differentially affect degree of entrapment (i.e., amount invested), depending upon the point in time at which they are introduced. The present studies were designed to test this notion. All subjects were given an initial monetary stake and had the opportunity to win more by taking part in an entrapping investment situation. In Experiment 1, half the subjects were provided with a payoff chart that made salient the costs associated with investing (Highcost salience condition) whereas half were not (Low-cost salience condition). Moreover, for half of the subjects the payoff chart was introduced before they were asked to invest (Early condition) whereas for the other half it was introduced after they had invested a considerable portion of their resources (Late condition). Entrapment was lower in the High salience-Early than in the Low salience-Early condition. However, there was no difference between groups in the Late condition. In Experiment 2, the perceived presence of an audience interacted with personality variables related to face-saving to effect entrapment. When the audience was described as “experts in decision making,” subjects high in public self-consciousness (or social anxiety) became less entrapped than those low on these dimensions. When the audience consisted of individuals who “wished simply to observe the experimental procedure,” however, high public self-consciousness (or social anxiety) individuals were significantly more entrapped than lows. Moreover, these interaction effects occurred when the audience was introduced late, but not early, into the entrapment situation. Taken together, these (and other) findings suggest that economic factors are more influential determinants of behavior in the earlier stages of an entrapping conflict, whereas face-saving variables are more potent in the later phases. Alternative explanations are discussed.

In a two-choice feeding test, a majority (13 of 14) of hungry domestic rats (Rattus norvegicus) rejected the intact carcass of a freshly sacrificed adult conspecific as food, and fed instead on a dead house mouse. Likewise, a majority (14 of 19) of domestic house mice (Mus musculus) rejected a dead conspecific as food, and fed instead on a rat. Mice subjected to social isolation prior to testing did not exhibit an aversion to feed on a dead conspecific. A response—competition model is proposed to account for the aversion by many species to feed on dead adult conspecifics.

Shortly after the University of Iowa implemented a new, integrated curriculum in 1974, a study of creativity was initiated because one goal of the process curriculum is to foster creativity. Hypotheses of no difference between beginning and graduating students and between old and new curriculum students were tested by means of Student's t test with Activities 5, 6, and 7 of Verbal Form A, Torrance Tests of Creative Thinking used as the criterion measure. The null hypotheses were rejected in favor of the beginning students and the old curriculum students, respectively (p less than .05). Hypotheses of no relationship between creativity and American College Testing scores and admit grade point average were tested by computing Pearson product moment correlation coefficients. All values of r were nonsignificant. Further research on a number of aspects of creativity in nursing is suggested.

The problem of predicting success in graduate education in nursing was addressed through a five-year study of students enrolled in four majors at the University of Iowa. Data from a sample of 198 graduates of the majors–medical–surgical nursing, nursing of children, psychiatric nursing, and nursing service administration–were analyzed to determine the efficiency of the traditional predictors, undergraduate grade point average (GPA) and Graduate Record Examination scores–verbal and quantitative–in predicting success in graduate education as measured by the masters GPA. Findings included support for the use of these predictor variables in the selection of graduate students in nursing and evidence that interprogram differences existed, indicating a need for different selection practices for the different majors.

A pilot survey conducted to determine the job satisfaction of a selected group of professional nurses employed on a float basis revealed that 76 percent of the nurses surveyed were satisfied with floating and 24 percent were dissatisfied. The nurses were asked to delineate advantages and disadvantages of the float assignment and to suggest measures that would improve the job satisfaction of the float nurse.
