PURPOSE: The purpose of this empirical research was to describe the contents what had happened to nurses experiencing taeoom. METHODS: This study explored the phenomenological ways to understand lived experiences in nurses' 'Taeoom' and investigated the 'Taeoom' through the deductive content analysis. For the this study, the data was collected through individual interviews with 11 nurses who worked over 12months in 1 hospital, lived in 5 areas, working 7 nursing unit of 10 hospitals. The interviews conducted by semi structured questions about participants' lived experiences in 'Taeoom'. RESULTS: Inductive contents analysis identified 5 categories and 15 subcategories. Main themes in this study included a failed membership, difficult of practical field adaptation, feared with nursing unit life, self-centered peer relationships and rite of passage. CONCLUSION: This study results have been illuminated with edged sword which has a dark side and a light side to experienced in 'Taeoom'. Newly employed nurses have suffering from 'Taeoom' as well as retained nurse. Therefore, policy and practice programs for a diminution of suffering and management for nurses 'Taeoom' should be developed and implemented.

In this study we investigated maternal Helicobacter felis (H. felis) infection status to determine the potential of maternal transmission. Pregnant Beagle dogs were infected experimentally with H. felis. Following the experimental design, the stools of the mother and litters were isolated and assessed for transmission of H. felis at parturition day, 1-week old age and 6-week old age respectively. Polymerase chain reaction (PCR) was used to examine the presence of transmitted H. felis. All litters showed no transmission of H. felis at parturition day. However, they revealed 14.3% and 100% at 1-week old age and 6-week old age respectively by PCR. These results suggested that vertical infection during prenatal period or delivery procedure is unlikely as a route of mother-to-child H. felis infection. It might be acquired H. felis through breast-feeding, contaminating saliva and fecal-oral during co-habitat.

Objective: Gastrointestinal (GI) bleeding is one of the most common reasons for people to visit the emergency department. Despite advances in treatments, the intensive care unit (ICU) admission rates due to GI bleeding are still high. Therefore, many scoring systems had been developed to screen patients who need active care. Among these scoring systems, the AIMS65 score, Glasgow-Blatchford score (GBS), and Pre-Rockall score (PRS) are known to be accurate risk assessment scoring models. A recent study has shown that hypoalbuminemia is related to poor prognosis in patients with GI bleeding. In this study, we compared the prognostic performance of the blood urea nitrogen to serum albumin ratio (B/A ratio) with the AIMS65, GBS, and PRS scores in patients with GI bleeding. Methods: This is a retrospective cohort study of patients presenting with GI bleeding in the Seoul Regional Emergency room from February to December 2018. The baseline characteristics of these patients were obtained. The data were compared with the prevalence of ICU admission from the emergency department and in-hospital mortality. The B/A ratio, AIMS65, GBS, and PRS scores as predictors of ICU admission and in-hospital mortality were evaluated using the area under the receiver operating characteristic (AUROC) curve. Results: A total of 433 patients were included in this study. Of these, 354 (81.8%) were admitted to the hospital, 121 (27.9%) were admitted to the ICU, and 26 (6.0%) died during hospitalization. Multivariate logistic regression analysis revealed that the B/A ratio was a significant predictor of ICU admission and in-hospital mortality. The predicting ICU admission AUROC value of the B/A ratio was 0.735, and those of the AIMS65, GBS, and PRS scores were 0.763, 0.741, and 0.704, respectively. For predicting in-hospital mortality, the AUROC value of the B/A ratio was 0.758, and those of the AIMS65, GBS, and PRS scores were 0.826, 0.717, and 0.744, respectively. Conclusion The B/A ratio is a useful tool for predicting the prognosis for patients with GI bleeding as are the AIMS65, GBS, and PRS score models.

Purpose: This study was conducted to identify factors affecting COVID-19 vaccination and associated side effects among health care workers in a small and medium-sized hospital. Methods: In May 2021, 301 workers out of a total of 670 working in a small and medium-sized hospital in Gyeonggi-do, were surveyed. The small and medium-sized hospital treats patients with COVID-19. Health care workers across different medical institutions responded with self-reported internet questionnaires. Factors influencing COVID-19 vaccination were analyzed via logistic regression. Results: Out of 301 subjects, 89.0% showed an intention to inoculate, and 85.7% were vaccinated against COVID-19. The most frequent reason for vaccination was responsibility as a medical worker. The fear of adverse reactions was the most frequent reason for non-vaccination. Adverse reactions after inoculation occurred in 70.9% of cases, and 30.6% were referred for treatment of adverse reactions. The factors ultimately influencing COVID-19 vaccination were vaccination intention, previous side effects from other vaccinations, occupation, and age. Conclusion In order to improve the effectiveness of COVID-19 vaccination, a systematic approach is required to determine the risk factors associated with the young age of the administrative staff/ personnel, subjects with a history of side effects associated with other vaccines, and health care workers who do not intend to be vaccinated. It is important to develop strategies to improve immunization. In addition, accurate and essential information regarding the side effects of vaccination is needed, along with appropriate education and publicity.

Feline endometrial adenocarcinomas are uncommon malignant neoplasms that have been poorly characterized to date. In this study, we describe a uterine adenocarcinoma in a Persian cat with feline leukemia virus infection. At the time of presentation, the cat, a female Persian chinchilla, was 2 years old. The cat underwent surgical ovariohystectomy. A cross-section of the uterine wall revealed a thickened uterine horn. The cat tested positive for feline leukemia virus as detected by polymerase chain reaction. Histopathological examination revealed uterine adenocarcinoma that had metastasized to the omentum, resulting in thickening and the formation of inflammatory lesions. Based on the histopathological findings, this case was diagnosed as a uterine adenocarcinoma with abdominal metastasis. To the best of our knowledge, this is the first report of a uterine adenocarcinoma with feline leukemia virus infection.

Cell culture systems for the protozoan Eimeria are not yet available. The present study was conducted to develop an animal model system by inoculating animals with a live Eimeria vaccine. This study was conducted on 3-day-old chickens (n = 20) pretreated with cyclophosphamide. The chickens were divided into 2 groups: the control group (n = 10) and the inoculated group that received the live Eimeria vaccine (n = 10). During the study period, we compared the clinical signs, changes in body weight, and number of oocysts shed in the feces of the control and inoculated group. This study showed that oocyst shedding was significantly higher in the chickens inoculated with live Eimeria oocysts than in the control chickens. Moreover, body weight gain was lesser in the animals in the inoculated group than in the control animals. Fecal oocyst shedding was observed in the inoculated animals. On the basis of these findings, we suggest that live Eimeria vaccination with cyclophosphamide pretreatment may be used to obtain an effective animal model for studying protozoan infections. This animal study model may eliminate the need for a tedious continuous animal inoculation process every 6 months because the live coccidiosis vaccine contains live oocysts.

Eimeria tenella and Eimeria maxima are important pathogens causing intracellular protozoa infections in laboratory avian animals and are known to affect experimental results obtained from contaminated animals. This study aimed to find a fast, sensitive, and efficient protocol for the molecular identification of E. tenella and E. maxima in experimental samples using chickens as laboratory avian animals. DNA was extracted from fecal samples collected from chickens and polymerase chain reaction (PCR) analysis was employed to detect E. tenella and E. maxima from the extracted DNA. The target nucleic acid fragments were specifically amplified by PCR. Feces secreting E. tenella and E. maxima were detected by a positive PCR reaction. In this study, we were able to successfully detect E. tenella and E. maxima using the molecular diagnostic method of PCR. As such, we recommended PCR for monitoring E. tenella and E. maxima in laboratory avian facilities.

An abnormal swelling was identified in the distal portion of the right femur in a 1-year-old non-obese diabetic (NOD) mouse. Grossly, a large mass of the distal femur was observed in the right femur. Lesions were poorly marginated, associated with destruction of the cancellous and cortical elements of the bone, and showed ossification within the soft tissue component. Histologically, the tumor was identified as a poorly differentiated sarcoma. Histopathologic examination of the bone masses revealed invasive proliferation of poorly differentiated neoplastic mesenchymal cells forming streams, bundles, and nests, which resulted in destruction of normal bone. Neoplastic cells exhibited random variation in cellular appearance and arrangement, as well as matrix composition and abundance. Haphazard and often intermingling patterns of osteogenic, chondroblastic, lipoblastic, and angiogenic tissues were present. Larger areas of neoplastic bone and hyaline cartilage contained multiple large areas of hemorrhage and necrosis bordered by neoplastic cells. The mass was diagnosed as an osteosarcoma. To our knowledge, this is the first spontaneous osteosarcoma in an NOD mouse.

Canine respiratory coronavirus (CRCoV) is commonly associated with canine kennel cough worldwide. Clinically infected dogs present coughing, sneezing, and nasal discharge. Severe infections may progress to pneumonia. Through serological surveys, CRCoV has been identified as a worldwide pathogen found in the respiratory tracts of dogs suffering from mild or severe respiratory disease. In this study, three dogs were obtained from a dog kennel. Over the previous 5 days, the dogs showed coughing, sneezing, and nasal discharge. To detect the etiologic pathogen, we performed multiplex RT-PCR (mRT-PCR) to amplify the genes encoding canine influenza virus matrix protein, canine distemper virus nucleocapsid protein, and CRCoV spike protein. Dot blotting was achieved with a CRCoV-specific probe. Nasal-secreting CRCoV was detected by the 442 bp CRCoV-positive PCR reaction in the nasal swabbing samples from dogs. Further, CRCoV-positive reactions by dot blot hybridization were detected in the nasal swabbing samples from dogs. In conclusion, we detected CRCoV in kenneled dogs with respiratory disease in Korea. Multiplex RT-PCR was able to detect successfully CRCoV infection in dogs. We suggest that mRT-PCR would be useful and effective for monitoring CRCoV infection in various kinds of dogs.
