Fogging and staining of a laparoscope lens negatively impact surgical visualization. We hypothesized that the disposable hot pack could not only warm but also clean laparoscopes. Hence, this study verified and developed the disposable hot pack with anti-fogging and cleaning function. The laparoscope was inserted into a swine abdominal cavity for five minutes. Then, the laparoscopic tip was heated with 65 °C saline or the folded disposable hot pack with nonwoven fabric coated surfactant for ten seconds (n = 15). Also, a laparoscopic tip with dirt was wiped with the prototype or conventional gauze for 10 s (n = 10). The dirt, fogging, and temperature of the laparoscopic tip were respectively evaluated after the laparoscope was inserted into the abdominal cavity. The laparoscopic tip temperature five minutes after insertion into the abdominal cavity was similar (31.1 °C vs 31.2 °C, p = 0.748) and there was no fogging in both methods. The conventional gauze had significantly less temperature of the laparoscopic tip after cleaning and higher fogging occurrence than the prototype (29.5 °C vs 34.0 °C, p < 0.001, 30% vs 0%, p = 0.030, respectively), although there was no dirt left after both methods. The disposable hot pack has a strong potential as an anti-fogging and cleaning device for use during laparoscopic surgery. [ABSTRACT FROM AUTHOR]

Aim: We developed an augmented reality technology‐based endotracheal aspiration simulation tool (the AR tool) consisting of three modes: a mode for nursing students to learn endotracheal aspiration by themselves (learning mode); a mode for repeated practice (practice mode); and a mode for confirmation testing (test mode). This study aimed to compare the learning outcomes of the AR tool with traditional training mannequins and identify potential uses and improvements of the AR tool. Methods: We invited students, and faculty members from the three universities who agreed to cooperate in conducting this study. Fifty‐four students and nine faculty members agreed to participate in this study. The students were divided into two groups. One group was to study with the AR tool and the other group was to study with the traditional half‐body training mannequin for suction. The students in both groups were asked to demonstrate endotracheal aspiration on another full‐body type training mannequin which could be used as a patient with a tracheostomy (Skill test). Group interviews with faculty members focused on the topic of the AR tool's potential use in nursing education and improvement needed. Results: There was little significant difference in the skill test results of endotracheal aspiration of students in both groups. The students and faculty members both expressed an interest in the AR tool. They said it was suitable for self‐study of endotracheal aspiration. Conclusions: This AR tool is an effective teaching tool for learning the sequence of endotracheal suctioning, although there are some areas that need improvement. [ABSTRACT FROM AUTHOR]

Japanese psychiatrists have proposed a new type of depression characterized by passing blame and irritability, which worsens on working days. This new type of depression is assumed to be closely associated with two personality traits: Interpersonal sensitivity, which reflects the tendency to be excessively concerned about or overreact to others' negative evaluations, and privileged self, which reflects the tendency to pursue own pleasures at the expense of maintaining harmony with others. Although a previous longitudinal study showed that these traits can lead to interpersonal stress generation among university students, it did not control for the influence of baseline negative events, nor use a scale that separately assessed negative dependent events caused by the participants' behaviors and negative independent events occurring outside the participants' control. The current study addressed these limitations and investigated whether interpersonal sensitivity and privileged self led to stress generation and increased depressive symptoms. Undergraduate and graduate students in Japan (N = 265) responded to self-report measures twice at an interval of four weeks. The results indicated that privileged self was related to an increase in subsequent experiences of negative dependent and independent events after controlling for either category of events experienced at the baseline. These findings suggest that privileged self can lead to stress generation or the perception that surrounding circumstances are worse than they are. Furthermore, privileged self was associated with an increase in subsequent depressive symptoms via experiences of negative interpersonal dependent events. [ABSTRACT FROM AUTHOR]
