PURPOSE: The purpose of this study was to investigate the reality of workplace violence experienced by emergency nurses and the relationship of violence response to professional quality of life. METHODS: The participants in this study were 899 emergency nurses from Korea nationwide. Data were obtained through an online survey done during October, 2017. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficient. RESULTS: Of the emergency nurses, 72.1% recognized that workplace violence is serious. Experience with workplace violence correlated positively with violence reaction (r=.32, p < .001), burnout (r=.20, p < .001) and secondary trauma (r=.22, p < .001). Also, reaction to violence was positively correlated with burnout (r=.28, p < .001) and secondary trauma (r=.56, p < .001). CONCLUSION: Findings indicate that the diverse workplace violence experienced by emergency nurses decreases their professional quality of life. Further study is needed to develop solutions to the problem of workplace violence in emergency settings.

Purpose: This study aimed to analyze factors affecting the intention to quit smoking in stroke patients. Methods: A descriptive approach was taken in this study. Structured questionnaires including subjects' characteristics, stroke symptom knowledge, attitudes towards smoking, social effect, self-efficacy, and intention to quit smoking were completed by eighty three patients in the outpatient stroke service. Data were analyzed with independent t-test, one-way ANOVA, Pearson’s correlation coefficients, and multiple regression using SPSS/WIN 22.0 program. Results: The subjects were all men and 95.2% of the subjects had a experience of smoking cessation education. There were significant differences in intention to quit smoking by marriage status (F=4.359, p=.007) and smokers existing in the family (t=-2.67, p=.009). The factors influencing intention to quit smoking in the stroke patient were self efficacy (β=.534, p<.001) and negative attitude toward smoking (β=.339, p<.001). Conclusion This results suggest to develop programs to increase self efficacy and negative attitude toward smoking. This study provides also reference of the importance of family support for quitting smoking.

Small-breed dogs (n = 168; weight < 15 kg) diagnosed with myxomatous mitral valve degeneration based on a routine clinical examination, radiology, electrocardiography, and echocardiography at the Seoul National University Veterinary Medical Teaching Hospital were included in this study. Survival periods were determined, and there were significant differences in survival rates among the three International Small Animal Cardiac Health Council classes. The mean follow-up period was 14.3 ± 12.1 months. Univariate analysis revealed that dyspnea, pulmonary edema, and vertebral heart score were significantly associated with survival time (p < 0.05). Additionally, age, left atrial-to-aortic root ratio, ejection fraction, and left ventricular end diastolic volume were associated with an increased risk of death (p < 0.1), while body weight, body condition score, systolic blood pressure, arrhythmia, syncope, fractional shortening, and end systolic volume were not associated with an increased risk of death. These results suggest that among the assessed variables dyspnea, pulmonary edema, and vertebral heart score could be useful prognostic factors for providing patient information to owners.

The present study was performed to determine the accuracy and reproducibility of calculating the mitral regurgitant orifice area with the proximal isovelocity surface area (PISA) method in dogs with experimental mitral regurgitation and in canine patients with chronic mitral insufficiency and to evaluate the effect of general anesthesia on mitral regurgitation. Eight adult, Beagle dogs for experimental mitral regurgitation and 11 small breed dogs with spontaneous mitral regurgitation were used. In 8 Beagle dogs, mild mitral regurgitation was created by disrupting mitral chordae or leaflets. Effective regurgitant orifice (ERO) area was measured by the PISA method and compared with the measurements simultaneously obtained by quantitative Doppler echocardiography 4 weeks after creation of mitral regurgitation. The same procedure was performed in 11 patients with isolated mitral regurgitation and in 8 Beagle dogs under two different protocols of general anesthesia. ERO and regurgitant stroke volume (RSV) by the PISA method correlated well with values by the quantitative Doppler technique with a small error in experimental dogs (r = 0.914 and r = 0.839) and 11 patients (r = 0.990 and r = 0.996). The isoflurane anesthetic echocardiography demonstrated a significant decrease of RSV, and there was no significant change in fractional shortening (FS), ERO area, LV end-diastolic and LV end-systolic volume. ERO area showed increasing tendency after ketamine-xylazine administration, but not statistically significant. RSV, LV end-systolic and LV end-diastolic volume increased significantly (p < 0.01), whereas FS significantly decreased (p < 0.01). The PISA method is accurate and reproducible in experimental mitral regurgitation model and in a clinical setting. ERO area is considered and preferred as a hemodynamic-nondependent factor than other traditional measurements.

Theophylline acts as a bronchodilator and has an anti-inflammatory effect. In addition, theophylline can be applied in patients where there are concerns regarding the side-effects of corticosteroids. This retrospective case series evaluated theophylline-based therapy in tracheal collapse (TC) canine patients. Forty-seven dogs with TC that received theophylline-based therapy during 2013–2017 were investigated. A fluoroscopic examination was performed to diagnose and grade TC. Theophylline was prescribed (7.5–30 mg/kg PO q12h) and the theophylline serum concentrations were measured. Coughing was assessed using a coughing scoring scale. The mean coughing score decreased after the theophylline-based therapy compared with that observed before treatment. Clinical improvements were observed in 46/47 patients (97.9%). As the intrathoracic TC grading increased, the final theophylline dosage also increased (p value 0.019). The symptom-free period (SFP) with therapy was 189.7 ± 194.45 days (range, 0–720 days) and there was no statistically significant correlation between the SFP and age, sex, or TC grade on fluoroscopy. Although theophylline has generally been used as a third-line treatment, it was used as the main treatment in this study and most patients showed improvements. Dogs have a wider therapeutic index of serum concentrations than humans, and any undesirable effects were easily overcome. With further research, this therapy may prove to be a useful approach, but its safety for long-term use in the treatment of canine TC patients needs to be established.
