    Abstract: This study used electroencephalography to explore the behavioral and electrophysiological effects of task interruption on performance. Background Task interruption is known to harm work performance, especially on working memory-related tasks. However, most studies pay little attention to cognitive processes by exploring brain activity and ignore the cumulative effect of sequential interruptions. Method Thirty-four healthy participants performed a spatial 2-back in three conditions: (1) interruptions with simple math questions, (2) suspensions with prolonged fixation cross, and (3) a pure 2-back. The measured outcomes comprise performance data, ERP amplitudes, EEG power, and subjective workload. Results Work performance decreased in the resumption trials, and cumulative interruptions had a more destructive effect on performance. EEG results showed that the P2 and P3 amplitudes induced by the 2-back task significantly increased after interruptions; theta and alpha power increased after interruptions. The P3 amplitude and alpha power induced by interruptions were significantly higher than that induced by suspensions. Conclusion Behavioral data revealed the disruptive effect of interruptions on postinterruption performance and the cumulative effect of interruptions on accuracy. Changes in ERP amplitudes and EEG power indicate the mechanisms of attention reallocation and working memory during interruptions. Larger P3 amplitudes and alpha power after interruptions than after suspensions suggested the inhibition of irrelevant information. These results may support the memory for goals model and improve the understanding of the effects of interruption on working memory. Application Focusing upon the mechanisms at play during the interruption process can support interruption management to ensure work safety and efficiency.

    Abstract: Spontaneous esophageal rupture (SER) is a rare but life-threatening condition with high mortality. The prognosis of patients with SER treated with surgical intervention or the traditional “three-tube” method is controversial. Thus, the aim of this study was to evaluate the clinical efficacy, feasibility, and safety of a new “two-tube” method involving a trans-fistula drainage tube and a three-lumen jejunal feeding tube for the treatment of SER without concomitant pleural rupture. Methods From January 2007 to June 2016, patients with SER and managed with the “two-tube” method or other methods were retrospectively analyzed. Data collected included initial presentation, procedure time, duration of treatment, numbers of patients with eventual healing of leaks, and complications. Results The average procedure time for the “two-tube” method was 22.1 ± 5.5 minutes. In comparison with the control method, the “two-tube” method had a similar diagnosis time (3.6 ± 1.4 vs. 3.4 ± 1.4 days) but a significantly higher successful closure rate (94.4% vs. 63.6%) and shorter treatment time (38.2 ± 5.6 vs. 53.6 ± 16.9 days). No complications associated with performance of the “two-tube” method occurred. Conclusion The “two-tube” method is an effective and safe approach for patients with SER.
