Investigation of the possibility of using an augmented reality-based endotracheal aspiration simulation tool for nursing education.

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.

Development of the differential detection reverse transcription loop-mediated isothermal amplification method for Barley yellow mosaic virus or Japanese soil-borne wheat mosaic virus from barley.

A differential detection reverse transcription loop-mediated isothermal amplification (DD-RT-LAMP) method was developed to detect either Barley yellow mosaic virus (BaYMV) or Japanese soil-borne wheat mosaic virus (JSBWMV) simultaneously. Both primer sets, which recognized either BaYMV or JSBWMV genomic RNA, amplified DNA more efficiently at 65°C using an isothermal DNA amplification and fluorescence detection device. Furthermore, these primer sets showed unique annealing curves. The peak annealing temperatures of BaYMV and JSBWMV amplification products using specific primer sets were 86.9°C-87.7°C and 84.5°C-85.0°C, respectively, and were clearly distinguishable during an annealing step following the isothermal amplification, monitored using a fluorescence detection device. In the field samples of barley (Hordeum vulgare L.) tested, BaYMV or JSBWMV were detected by DD-RT-LAMP, and the detection results of DD-RT-LAMP were correspondent with the results of reverse transcription-PCR.

Molecular detection of canine respiratory pathogens between 2017 and 2018 in Japan.

A molecular survey was conducted to understand recent distribution of pathogens associated with canine infectious respiratory disease (CIRD) in Japan. Nasal and/or pharyngeal swabs were collected from asymptomatic dogs and those with CIRD, living in private house or in kennels. PCR-based examination was conducted for detecting nine pathogens. Among private household dogs, 50.8% with CIRD, 11.1% with respiratory disease other than CIRD, and 4.3% asymptomatic were positive for more than one pathogen, whereas in kennel-housed dogs, 42.9% with CIRD and 27.3% asymptomatic were positive. Bordetella bronchiseptica was most frequently detected, followed by canine herpesvirus 1, canine parainfluenza virus, canine pneumovirus, Mycoplasma cynos, and canine adenovirus type 2. In kennel environment, asymptomatic dogs might act as reservoirs carrying the respiratory pathogens.

[Examination of the effects of a role-playing training program for the improvement of planning and management skills of public health nurses].

Objectives　The Japan Health Insurance Association (JHIA) conducts training in each branch facility to improve the ability of public health nurses (PHNs). The headquarters of the PHNs of JHIA and the researchers conducted a training program for leaders of PHNs at each JHIA branch. The goal of the program was to create a training plan using role-play to acquire facilitation skills. This study aimed to examine the effects of training.Methods　The study was designed in accordance with the Instructional Designs. The training goals were as follows: (1) understanding the role of facilitation and the facilitator in the debriefing session after the role-play, (2) understanding facilitation techniques, (3) being confident in performing as facilitators in the debriefing session; and (4) conducting the debriefing sessions using facilitation skills. The evaluation of the training was based on the Kirkpatrick model from the viewpoint of confidence in using facilitation, knowledge of facilitation, and conduct of training and utilization of facilitation technology. Questionnaire evaluations were conducted three times before the training, immediately after the training, and three months after the training. In August 2016, 4.5 hours of training were conducted in one day.Results　There were 79 participants in the training group. The mean points of knowledge and confidence were 2.6-3.6 before training, 6.3-7.9 after training, and 6.0-6.9 at 3 months after training. The participants rated their interest in three questions of the training as high as 8.1-8.6. In addition, 64.6% of participants held a role-play session at each branch within three months of the initial training. In the role-play session planned by the participants, the practitioners implemented the explanation of the purpose and the rules at each branch 96.1% and 98.0%, respectively. Participants who had attended facilitation training prior to our program scored higher points of knowledge and confidence before and after three months. Three months after the training, 79 participants responded to the question of the role of the facilitator in role-playing. The descriptions were categorized into "opinions on the basics and planning of role-play training" and "opinions on the roles in retrospectives."Conclusion　The participants evaluated the training contents and the materials used as appropriate, and their knowledge and confidence in facilitation improved after the training. To maintain and improve facilitation skills, the educational system needs to implement training using role-playing at each branch consistently.

SURVEILLANCE FOR ANTIBODIES AGAINST SIX CANINE VIRUSES IN WILD RACCOONS (PROCYON LOTOR) IN JAPAN.

Raccoons (Procyon lotor) are found worldwide. They are frequently seen in crowded inner cities as well as in forests or wooded areas, often living in proximity to humans and their pets. We examined sera from 100 wild raccoons in Japan for antibodies to six canine viruses with veterinary significance to assess their potential as reservoirs. We also aimed to understand the distribution of potentially infected wildlife. We found that 7% of samples were seropositive for canine distemper virus (CDV), 10% for canine parvovirus type 2, 2% for canine adenovirus type 1, 6% for canine adenovirus type 2, and 7% for canine coronavirus. No samples were found to be seropositive for canine parainfluenza virus. Seropositivity rates for canine distemper virus and canine parvovirus type 2 were significantly different between areas, and younger raccoons (<1 yr old) were more frequently seropositive than older raccoons. Because raccoons belong to the suborder Caniformia, similar to dogs (Canis lupus familiaris), our results suggest that they can act as reservoirs for some of these important canine viruses and might be involved in viral transmission. Further study should include isolation and analysis of canine viruses in wild raccoons from a wider area.
