7. Creativity under Attack: How People's Role in Competitive Conflict Shapes Their Creative Idea Generation

Author

Van Leeuwen, Wouter and Baas, Matthijs

Abstract

Although creativity is helpful if not needed to deal with conflicts, research on the effects of conflict on creativity shows inconsistent findings. In this study, the possibility that effects may depend on people's role in conflict was considered. Whether, when, and why assuming the role of attacker or defender in conflict affects creative idea generation was therefore investigated. The prediction was tested if attackers are more creative than defenders. In addition, control over the situation as a moderating variable and anxiety as a mediator were considered. Participants (n = 115, M[subscript age] = 22.06, SD[subscript age] = 2.75, 83 women) were recruited in Amsterdam, the Netherlands, and were randomly assigned to an attacker, defender, or role control condition. Controllability over the situation was manipulated within-subjects and anxiety and creativity were measured during 2 rounds of idea generation. Results revealed no differences in creative performance and anxiety between defenders and attackers and that defenders generated a greater number of ideas than people in the role control condition. Exploratory analyses further revealed that attackers and defenders generated a greater number of aggressive ideas. Finally, attackers and defenders experienced more anxiety, but increased anxiety did not account for observed differences in the number of (aggressive) ideas. The effect of controllability could not be investigated due to a failed manipulation. Limitations and implications are discussed.

Abstract

Early postoperative sinus node dysfunction (SND) is common in paediatric patients undergoing surgical correction of congenital heart disease (CHD). At present, the pathophysiology of these arrhythmias is incompletely understood. In this case series, we present 3 paediatric patients in whom we performed intraoperative epicardial mapping and who developed early postoperative SND. All patients had either an inferior or multiple sinoatrial node (SAN) exit sites, in addition to extensive conduction disorders at superior and inferior right atrium. Our findings contribute to the hypothesis that pre-existing alterations in SAN exit sites in combination with atrial conduction disorders may predispose paediatric patients with CHD for early postoperative SND. Such insights into the development of arrhythmias are crucial as it may be the first step in identifying high-risk patients.

Abstract

Background: Sinus node dysfunction (SND) and atrial tachyarrhythmias frequently co-exist in the aging patient with congenital heart disease (CHD), even after surgical correction early in life. We examined differences in electrophysiological properties of the sino-atrial node (SAN) area between pediatric and adult patients with CHD. Methods: Epicardial mapping of the SAN was performed during sinus rhythm in 12 pediatric (0.6 [0.4–2.4] years) and 15 adult (47 [40–55] years) patients. Unipolar potentials were classified as single-, short or long double- and fractionated potentials. Unipolar voltage, relative R-to-S-amplitude ratio and duration of all potentials was calculated. Conduction velocity (CV) and the amount of conduction block (CB) was calculated. Results: SAN activity in pediatric patients was solely observed near the junction of the superior caval vein and the right atrium, while in adults SAN activity was observed even up to the middle part of the right atrium. Compared to pediatric patients, the SAN region of adults was characterized by lower CV, lower voltages, more CB and a higher degree of fractionation. At the earliest site of activation, single potentials from pediatrics consisted of broad monophasic S-waves with high amplitudes, while adults had smaller rS-potentials with longer duration which were more often fractionated. Conclusions: Compared to pediatric patients, adults with uncorrected CHD have more inhomogeneous conduction and variations in preferential SAN exit site, which are presumable caused by aging related remodeling. Long-term follow-up of these patients is essential to demonstrate whether these changes are related to development of SND and also atrial tachyarrhythmias early in life.

28. Native valve, prosthetic valve, and cardiac device-related infective endocarditis:A review and update on current innovative diagnostic and therapeutic strategies

Author

Kouijzer, Joop J.P., Noordermeer, Daniëlle J., van Leeuwen, Wouter J., Verkaik, Nelianne J., Lattwein, Kirby R., Kouijzer, Joop J.P., Noordermeer, Daniëlle J., van Leeuwen, Wouter J., Verkaik, Nelianne J., and Lattwein, Kirby R.

Abstract

Infective endocarditis (IE) is a life-threatening microbial infection of native and prosthetic heart valves, endocardial surface, and/or indwelling cardiac device. Prevalence of IE is increasing and mortality has not significantly improved despite technological advances. This review provides an updated overview using recent literature on the clinical presentation, diagnosis, imaging, causative pathogens, treatment, and outcomes in native valve, prosthetic valve, and cardiac device-related IE. In addition, the experimental approaches used in IE research to improve the understanding of disease mechanisms and the current diagnostic pipelines are discussed, as well as potential innovative diagnostic and therapeutic strategies. This will ultimately help towards deriving better diagnostic tools and treatments to improve IE patient outcomes.

Abstract

The Thoraxcenter of Erasmus MC started an improvement project in 2015 in order to increase the number of open-heart surgeries by 150 for three consecutive years (450 in total, +46%), and to decrease the access time from 12-14 to 2-3 weeks by the end of 2016. This was required to attain economy of scale in a highly competitive market. In this paper we describe the first year of the project, focusing on its structure and interventions taken, resulting in 165 additional open-heart surgeries carried out in 2016 and a significantly shorter access time of 2-3 weeks.

45. Unplanned Reoperation and Implant Revision After Total Wrist Arthroplasty.

Author

Pong, Taylor M., van Leeuwen, Wouter F., Oflazoglu, Kamil, Blazar, Philip E., and Chen, Neal

Abstract

Background: Total wrist arthroplasty (TWA) is a treatment option for many debilitating wrist conditions. With recent improvements in implant design, indications for TWA have broadened. However, despite these improvements, there are still complications associated with TWA, such as unplanned reoperation and eventual implant removal. The goal of this study was to identify risk factors for an unplanned reoperation or implant revision after a TWA at 2 academic medical centers between 2002 and 2015. Methods: In this retrospective study, 24 consecutive TWAs were identified using CPT codes. Medical records were manually reviewed to identify demographic, patient- or disease-related, and surgery-related risk factors for reoperation and implant removal after a primary TWA. Results: Forty-six percent of wrists (11 of 24 TWAs performed) had a reoperation after a median of 3.4 years, while 29% (7 of 24) underwent implant revision after a median of 5 years. Two patients had wrist surgery prior to their TWA, both eventually had their implant removed (P =. 08). There were no risk factors associated with reoperation or implant removal. Conclusion: Unplanned reoperation and implant removal after a primary TWA are common. Approximately 1 in 3 wrists are likely to undergo revision surgery. We found no factors associated with reoperation or implant removal; however, prior wrist surgery showed a trend toward risk of implant removal after TWA. [ABSTRACT FROM AUTHOR]
