Purpose: This study aimed to identify the changes in psychological distress and the quality of life in patients with esophageal cancer from pre-surgery to 3 months after surgery. Methods: We enrolled 49 patients scheduled to undergo esophageal surgery at a tertiary hospital in Seoul, South Korea. Patients’ psychological distress and quality of life were assessed using the Korean scales, such as the Hospital Anxiety and Depression Scale (HADS), European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ-C30), and an esophageal cancer-specific questionnaire (QLQ-OES18) at pre-surgery, 1 month, and 3 months post-surgery. Results: Moderate-to-severe anxiety was reported in 12.2% of patients at the pre-surgery evaluation, 57.1% of patients at 1 month post-surgery, and 8.2% at 3 months post-surgery. Moderate-to-severe depression was reported in 12.2% of patients at the pre-surgery evaluation, 63.3% at 1 month post-surgery, and 16.3% of patients at 3 months post-surgery. Clinically significant, moderate changes (10~20 points) in physical functioning, insomnia, nausea and vomiting, and dyspnea (per EORTC QLQ-C30) and dysphagia and taste problems (per QLQ-OES18) were reported from pre-surgery to 1 month post-surgery. Conclusion One month after esophageal cancer surgery, patients demonstrated severe psychological distress and worsening quality of life. Nursing intervention is needed to relieve psychological distress and improve the quality of life in patients with esophageal cancer in the 1-month early recovery period.

PURPOSE: This study aimed to identify the influence of job stress, compassion satisfaction, and resilience on depression of nurses. METHODS: One hundred seventy six nurses working at one tertiary hospital in one metropolitan city were included. The data collection was conducted from September 1st to October 1st, 2018, using a structured, self-reported questionnaire. The collected data were analyzed using descriptive statistics, t-test, one-way ANOVA, Pearson's correlation coefficients, and multiple regression. RESULTS: The M±SD age of 170 subjects was 29.62±5.59. Depression had significant negative correlations with compassion satisfaction (r=−.50, p < .001) and resilience (r=−.56, p < .001), and a positive correlation with job stress (r=.42, p < .001). In the multiple regression analysis, marital status (β=−.15, p=.015), job stress (β=−.00, p < .001) and resilience (β=−5.47, p < .001) had a significant effect on depression. The explanatory power of the subject's marital status, leisure life, job stress, compassion satisfaction, and resilience on depression was 44.1% (F=27.62, p < .001). CONCLUSION The study results showed that single status, low job stress, high resilience may decrease depression of nurses. Reducing job stress and improving resilience of nurses will virtually contribute to reduce their depression that can influence on not only nurses' health status but also their performance and qualitative caring for patients.

A 35-year-old man presented with progressive dyspnea and hemoptysis. His blood pressure was 230/140 mmHg and serum creatinine level was 20.13 mg/dL. Chest radiography and computed tomography revealed pulmonary hemorrhage. His renal function was low, thus emergent renal replacement therapy was required. Malignant hypertension and acute kidney injury were diagnosed, and antihypertensive therapy and hemodialysis started immediately. Renal biopsy was performed to examine the underlying disease. Typical pathological changes of malignant hypertension, fibrinoid necrosis of the afferent arterioles, and proliferative endoarteritis at the interlobular arteries were observed. His renal function improved gradually and pulmonary hemorrhage completely disappeared with administration of antihypertensive agents. Here, we report this rare case of malignant hypertension with pulmonary alveolar hemorrhage and speculate that the hemorrhage may be related to vascular injuries at the alveolar capillary level caused by malignant hypertension.

PURPOSE: This study evaluated the effect of polishing techniques on surface roughness of polymethyl methacrylate (PMMA), as well as the influence of light-cured surface glaze and subsequent brushing on surface roughness. MATERIALS AND METHODS: A total of 60 PMMA specimens (10x10x5 mm) were made and then divided into 6 groups of 10 each according to the polymerization methods (under pressure or atmosphere) and the surface polishing methods (mechanical or chemical polishing) including 2 control groups. The mechanical polishing was performed with the carbide denture bur, rubber points and then pumice and lathe wheel. The chemical polishing was performed by applying a light-cured surface glaze (Plaquit(R); Dreve-Dentamid GmbH). Accura 2000(R), a non-contact, non-destructive, optical 3-dimensional surface analysis system, was used to measure the surface roughness (Ra) and 3-dimensional images were acquired. The surface roughness was again measured after ultrasonic tooth brushing in order to evaluate the influence of brushing on the surface roughness. The statistical analysis was performed with Mann-Whitney test and t-test using a 95% level of confidence. RESULTS: The chemically polished group showed a statistically lower mean surface roughness in comparison to the mechanically polished group (P = .0045) and the specimens polymerized under the atmospheric pressure presented a more significant difference (P = .0138). After brushing, all of the groups, except the mechanically polished group, presented rougher surfaces and showed no statistically significant differences between groups. CONCLUSION: Although the surface roughness increased after brushing, the chemical polishing technique presented an improved surface condition in comparison to the mechanical polishing technique.

Several outbreaks of Getah virus (GETV) have been reported in horses and pigs, causing large economic losses. However, there have been no reports describing serological survey for GETV in South Korea pigs. The present study conducted serological survey of GETV in South Korean pigs. A total of 670 whole blood samples were collected from domestic pigs. The overall seropositive rate was 26.4%, higher than the rates observed in racehorses in 2013–2014. Preparations for epidemics of novel diseases caused by climate change should include regular serological survey for these diseases, including GETV, and the development of vaccines against novel pathogens.

PURPOSE: The aim of this study was to investigate the change of nutritional status and the incidence of dumping syndrome after gastrectomy for gastric cancer. METHODS: From January 2013 to May 2014, 36 patients who underwent gastrectomy for gastric cancer were prospectively investigated in terms of nutritional status by body weight, anthropometric measurements, biochemical data, and Patient-Generated Subjective Global Assessment (PG-SGA). Dumping syndrome was assessed using a newly developed questionnaire based on the Japanese Society of Gastroenterological Surgery survey and Sigstad's scoring system. RESULTS: Body weight losses were 4.6%, 8.1%, and 6.9% at discharge, six months, and one year after discharge, respectively. Triceps skinfold thickness had no significance, however, mid-arm muscle circumference showed significant loss after gastrectomy. A part of the biochemical data showed significant change after gastrectomy, but almost indicated a restoring tendency within two months after discharge. In terms of PG-SGA, 33 patients (91.7%) were classified as A (well-nourished) before surgery, however, the number of well-nourished patients showed a sharp decrease to 1 (2.8%) at two weeks after discharge, and then gradually increased to 25 (69.4%) at one year. The main obstacles against diet intake were reported as 'early satiety' and 'anxiety'. The number of patients who had experience in at least one dumping syndrome related symptom was 21 (58.3%) at discharge, 26 (72.2%) at two months after discharge, and 11 (30.6%) at one year after discharge. CONCLUSION: Nutritional deficit as well as dumping syndrome is encountered in a large number of gastric cancer patients after gastrectomy. Postoperative nutritional support and personalized education seem to be very important during the postoperative period.

Incidences of major feline viral diseases provide basic information for preventing viral disease in cats. Despite the growing interest in feline viral diseases, sero-surveillances have been lacking. In this study, we analyzed the diagnoses of feline viral diseases and conducted a sero surveillance of feline panleukopenia virus (FPV), feline calicivirus (FCV), feline herpesvirus-1 (FHV-1), and feline infectious peritonitis virus (FIPV) in Korean cats. Of the 204 confirmed cases since 2015, the numbers of diagnoses for FPV, FIPV, FCV, feline influenza virus, and FHV-1 were 156, 32, 12, 3, and 1 case, respectively. In total, 200 sera, collected between 2019 and 2021, were screened for the presence of antibodies against FPV, 2 FCVs, FHV-1, and FIPV using a hemagglutination inhibition test and a virus-neutralizing assay (VNA). The overall seropositive rates in cats tested for FPV, the 2 FCVs, FHV-1, and FIPV were 92.5%. 42.0%, 37.0%, 52.0%, and 14.0%, respectively. A low correlation (r = 0.466) was detected between the VNA titers of 2 FCV strains. The highest incidence and seropositive rate of FPV reveal that FPV is circulating in Korean cats. The low r-value between 2 FCVs suggests that a new feline vaccine containing the 2 kinds of FCVs is required.

Animals imported from abroad are a cause of rabies outbreaks in many countries. Therefore, rabies serology testing for dogs and cats traveling abroad is an important measure to reduce the incidence of rabies. Rabies virus antibodies were measured in sera collected from 2,367 dogs and 894 cats between 2017 and 2021. A serum sample with a value of 0.5 IU/mL or higher was considered a pass. The overall pass rates for rabies virus were 96.4% in dogs and 98.4% in cats. The mean rabies virus neutralization assay titers were higher in cats than in dogs and in female than in male animals. According to age, 6-year-old dogs and 9-year-old cats had the highest virus neutralization assay titers. Of the failure cases, 53.0% (53/100) were dogs or cats less than 1 year old. Although the average failure rates in dogs and cats were low at 3.5% and 1.6%, respectively, the factors influencing failure were age and vaccine manufacturer. Therefore, it is necessary to observe the vaccination interval and timing of blood collection after boosting.

This study was carried out to examine the proportion of fatty acids and contents of trans fatty acid in commercial processed foods in Jeon-Buk area. Contents of trans fatty acid in bakery products ranged from 0.2% to 1.0% per 100 g food. Especially garlic bread and pastry contained the highest amount. Popcorns contained trans fatty acid from 0.0% to 13.4%. Among them, instant popcorns for microwave contained the highest amount, while trans fatty acid was hardly detected in popcorns for theater. And trans fatty acid detected in popcorns was mostly in the form of 18 : 1 trans. The content of trans fatty acid in pizza was nearly 0.2%. Amounts of saturated fatty acid and unsaturated fatty acid were similar between each type of pizza and frozen pizza. Fritters such as fried chickens and vegetables contained trans fatty acid less than 0.2% per 100 g food.
