    data set suggests that approximately only 1 in 5 patients with POAF after isolated CABG got prescribed OAC.Adult cor triatriatum sinister associated with severe mitral regurgitation is extremely rare. As these obstructive cor triatriatum feature hemodynamics that mimic mitral stenosis, a pressure load is theoretically generated only on the left atrial proximal chamber, and therefore the left ventricle is less likely to suffer volume loading. Here, we report a surgical case with such rare hemodynamics. A 22-year-old man with obstructive cor triatriatum and severe mitral regurgitation received an anomalous membrane excision and mitral annuloplasty. An abnormal membrane with an orifice 7 mm in size was completely resected while a grossly dilated mitral annulus was repaired via annuloplasty ring. Mitral regurgitation was controlled well, and the postoperative course was uneventful. Even with obstructive cor triatriatum, severe mitral annular dilatation and subsequent left ventricular dilatation may occur, causing the progressive heart failure encountered in this case.

    Reducing the leg wound morbidity is crucial for the patients undergoing coronary artery bypass grafting (CABG) with great saphenous vein (SV) grafts harvested by no-touch (NT) technique. This study was to summarize the experience of skin bridging technique for reducing wound morbidity and the influence of it on one-year bypass graft patency.

    According to skin bridging or not, harvesting times, graft length, number of bleeding branches, postoperative subjective perception assessment scale (ASEPSIS) scores and one-year patency rate were analyzed.

    From June 2018 to February 2019, 60 patients underwent CABG with SV grafts either with open-incision NT or skin bridging NT (30 in each group). There were no significant differences in age (71.4 ± 5.1 years vs. Epigenetic screening 68.9 ± 5.5 years) or graft length (23.3 ± 1.1 cm vs. 23.9 ± 1.3 cm) between the two groups. The bridging/NT group had a significantly longer harvest time (38.5 ± 4.9 min vs. 18.5 ± 2.6 min; P < 0.001) and a significantly greater number of bleeding branches (1.9 ± 1.2 vs. 0.8 ± 0.8; P < 0.001) than the open NT group. The open NT group had a significantly higher ASEPSIS score (23.8 ± 2.0 vs. 15.7 ± 2.6; P < 0.001). There was no significant difference in patency rate at one-year follow-up.

    Obtaining the SV by the combined NT/discontinuous skin bridging technique is a satisfactory method for patients who underwent CABG. This method has important clinical significance in reducing wound morbidity in the harvest of NT grafts.

While the interview part is necessary, the concept that one should be resting during that year is a myth. In fact, nothing could be further from the truth. Your top priority should be to prepare yourself to hit the ground running as a great surgical intern.To further the understanding of how to build or reduce synchrony in a work team, we examined two principles for defining the optimal condition to produce or limit synchrony (a) the empath-driver ratio (relative strength of the stronger influencer compared to the receptive strength of any member in the group), and (b) the balance between autocorrelated autonomic arousal (degree to which members’ signals are independent of other group members) and the degree of influence that transfers from each group member to other group members. In study 1, we employed a series of computational simulations designed to manipulate the four variables. The results indicated that there is a four-way balance between driver strength, empath strength, autocorrelational and transfer effects among team members. The relationship between the synchronization coefficient and the empath-driver ratio was moderated by whether the group adopted a network structure for group problem solving or command-and-control. In study 2 we analyzed autonomic arousal (electrodermal response) in four teams of five participants playing a first-person shooter computer game. The correlation between the synchronization coefficient and the empath-driver ratio was 0.280 (p less then .001) based on 64 pairs of observations. The relationship was moderated by both the network structure and the statistical model that one adopted to analyze dyadic relationships within the group. The implications of these relationships for a growing theory of team synchrony are discussed.The present study explores the role of convergent and divergent thinking in learning sciences from the nonlinear dynamical system (NDS) perspective. The participants (N=375) were fifth and sixth graders, aged 11-12, who were taking an introductory course in science. Students’ understanding of physical phenomena, such as melting, boiling and evaporation was investigated as a function of four neo-Piagetian constructs via the difference-equation cusp catastrophe model. The nonlinear models where logical thinking acted as the asymmetry factor and field dependence/ independence, convergent thinking and divergent thinking acted as bifurcation factors, were superior, explaining 43-44% of the variance, whereas their linear alternatives explained 0-18%. Empirical evidence regarding the role of the above neo-Piagetian constructs at these early ages is reported for the first time and contributes to theory development within the NDS framework. Further, discussion about the significance of the findings is provided.Gaze behavior represents a complex phenomenon in social inter-action. We focus here on dyadic face-to-face interaction during naturally occurring verbal exchanges, where shared attention can be operationalized by joint gazes and eye contact. A multi-step methodology for the analysis of eye synchrony is presented, exemplified by a single case. The dynamics of face-to-face interaction allows estimating the degree of interlocutors’ synchrony. While there is growing evidence for interpersonal synchrony of various behavioral and physiological signals, eye synchrony has not yet been studied outside the laboratory. The method presented is based on time series of gaze behavior acquired by mobile eye tracking devices. We applied windowed cross-correlations to the data and used surrogate testing to attain effect sizes even for single interactions (Surrogate Synchrony, SUSY). SUSY thus integrates nomo-thetic with idiographic research goals The nomothetic interest is to test hypotheses that gaze behavior may be generally synchronized and linked with psychological variables.
