p53 gene alterations in the ovarian cancers are regarded as early events in the whole process of carcinogenesis. This study is intended to compare p53 protein expression rate in the ovarian surface epithelial tumors according to histologic types, degree of malignancy and differentiation. 134 cases of ovarian epithelial tumors including 26 cases of serous cystadenoma, 7 cases of serous borderline malignancy, 15 cases of serous cystadenocarcinoma, 40 cases of mucinous cystadenoma, 21 cases of mucinous borderline malignancy, 20 cases of mucinous cystadenocarcinoma, 4 cases of endometrioid carcinoma, and 1 case of clear cell carcinoma were studied. Immunohistochemistry using monoclonal p53 antibody(DO-7) was applied to the routine formalin-fixed paraffin embedded tissue. The results were as follows; 1. No immunohistochemical positivity of p53 protein was found in all 66 cases of benign serous and mucinous tumors studied. 2. There was no significant difference of p53 protein expression between serous and mucinous malignant tumors. 3. The expression rate of p53 protein exhibited a statistically significant difference between borderline(42%) and malignant(74%) ovarian surface epithelial tumors (p<0.05). 4. The expression rate of p53 protein of poorly differentiated carcinomas(100%) was higher than those of moderately (88%) and well differentiated carcinomas(60%), but there was no statistical significance. In summary, p53 protein expression might be a good indicator of malignant transformation of the ovarian surface epithelial tumors.

Angiogenesis is essential for tumor growth and metastasis, however, the prognostic value of neovascularization is undetermined. The aim of this study is to evaluate the prognostic significance of microvessel density (MVD) and vascular endothelial growth factor (VEGF) expression in breast carcinomas. An immunohistochemical stains for CD 31 (DAKO) to estimate MVD and VEGF (Santa Cruz) were done on 40 cases of invasive breast carcinoma. MVD was calculated as an average count of vessels per 200 power field in the most vascularized areas. VEGF expression was interpreted according to staining intensity and number of positive cells. Mean MVD was 35, and MVD was not correlated with lymph node metastasis or histologic grade, but high MVD (mean MVD>35) showed an increasing tendency in cases with larger size, negative ER/PR, and positive cathepsin D. All of the cases showed VEGF expression, but VEGF expression was not correlated with tumor size, histologic grade, lymph node metastasis, ER/PR status, and cathepsin D expression. These results suggest that MVD and VEGF expressions are not reliable prognostic factors.

Purpose:
The purpose of this study was to understand and describe the experiences of nurses in charge of COVID-19 screening at general hospitals in South Korea.
Methods:
Data were collected through individual in-depth interviews with 14 nurses who had been working for more than a month at a screening clinic operated by two general hospitals from May 11 to July 20, 2021. Verbatim transcripts were analyzed using Colaizzi’s phenomenological analysis.
Results:
As a result of analysis, four theme clusters were extracted from nurses’ experiences, as follow: the role of the hospital gatekeeper entrusted with managing the COVID-19 pandemic, struggling to maintain the protective barrier, boundlessness like a Mobius strip, and driving force to endure as a nurse in charge of COVID-19 screening.
Conclusion
The results of this study provide a deeper understanding of the lives of screening clinic nurses who are struggling with the COVID-19 situation. The results are expected to be useful in providing basic data for improving the infection control system and response strategies that can be applied to nursing practice in other pandemic situations.

PURPOSE: The purpose of this cross-over experimental study was to examine effects of music intervention on maternal anxiety, fetal heart rate pattern and testing time during non-stress tests (NST) for antenatal fetal assessment. METHODS: Sixty pregnant women within 28 to 40 gestational weeks were randomly assigned to either the experimental group (n=30) or control group (n=30). Music intervention was provided to pregnant women in the experimental group during NST. Degree of maternal anxiety and fetal heart rate pattern were our primary outcomes. State-trait anxiety inventory, blood pressure, pulse rate, and changes in peripheral skin temperature were assessed to determine the degree of maternal anxiety. Baseline fetal heart rate, frequency of acceleration in fetal heart rate, fetal movement test and testing time for reactive NST were assessed to measure the fetal heart rate pattern. RESULTS: The experimental group showed significantly lower scores in state anxiety than the control group. There were no significant differences in systolic blood pressure and pulse rate between the two groups. Baseline fetal heart rate was significantly lower in the experimental group than in the control group. Frequency of acceleration in fetal heart rate was significantly increased in the experimental group compared to the control group. There were no significant differences in fetal movement and testing time for reactive NST between the two groups. CONCLUSION: Present results suggest that music intervention could be an effective nursing intervention for alel viating anxiety during non-stress test.

OBJECTIVE: Considerable research has been conducted on the relationship between alcohol consumption and metabolic syndrome. Although various standards for the amount and frequency of alcohol consumption have been suggested, a tool to measure individual alcohol use behavior against a consistent standard is required. Moreover, the association of alcohol use behavior with health should be examined on the basis of such a standard. In this study, we examined the relationships between alcohol use behavior according to the Alcohol Use Disorders Identification Test (AUDIT) and metabolic syndrome and its components in Korean women. METHODS: This study utilized data from the fifth Korean National Health and Nutrition Examination Survey, which was administered from 2010 through 2012. We investigated the relationships between alcohol use behavior and metabolic syndrome and its components in a sample of 2,906 women by using analysis of covariance and logistic regression analysis. RESULTS: After adjusting for confounding variables, alcohol use behavior was significantly associated with metabolic syndrome [odds ratio (OR) 2.877; 95% confidence interval (CI) 1.523–5.435 in the problem use group]. AUDIT score also was significantly related to abdominal obesity (OR 2.263; 95% CI 1.704–4.459 in the problem use group), hypertension (OR 3.377; 95% CI 1.871–6.095 in the problem use group), hypertriglyceridemia (OR 3.204; 95% CI 1.800–5.702 in the problem use group), and impaired fasting glucose (OR 3.034; 95% CI 1.721–5.348 in the problem use group). CONCLUSION: In this study, positive associations were observed between AUDIT score and risk of metabolic syndrome and its components.

OBJECTIVES: This study examined the practices of a community meal program for older adults in rural areas during the agricultural off-season. METHODS: A survey was conducted from December 12 to December 22, 2016. Self-administered questionnaires were distributed to 150 cooking volunteers, who had participated in the community meal program in 50 villages. A total of 114 responses were returned from 44 villages and used for data analysis. In addition, in-depth interviews were conducted with the volunteers of eight villages. RESULTS: Most of the cooking volunteers were 50 years old or older and they participated in serving older adults meals for good will. The cooking volunteers perceived that the older adults in their community did not eat various foods, had difficulties in grocery shopping, and frequently consumed salty foods. During the agricultural off-season, 40.9% of villages served the older adults meals 6–7 days a week and 95.5% provided meals for lunch. An average of 21 to 40 older adults were served meals in each village. The cooking volunteers reported that the food preparation and meal service times were sufficient, recipes provided were useful, and menus met the preference of the older adults. At the end of the program, they felt proud of serving meals for older adults in the community. An increased awareness of healthy eating, interest in health, and consumption of nutritious meals, a decrease in loneliness among older adults, and the promotion of fellowship in the community were rated highly. The cooking volunteers expected additional support for cooking personnel and insisted that the program should be provided for the entire agricultural off-seasons. CONCLUSIONS: The community meal program during the agricultural off-season for the elderly in rural areas was effective in improving the dietary life of older adults, relieving their feelings of isolation, and promoting fellowship of the community. The volunteers felt workload due to a shortage of volunteers but answered that they were rewarded by helping older adults in their community.

Background:
Abnormal chest radiographs are frequently encountered in patients with scrub typhus. This study aimed to investigate whether chest radiography on admission is significant as a predictive factor for acute kidney injury (AKI) in patients with scrub typhus.
Methods:
From 2010 to 2016, 467 patients were diagnosed with scrub typhus in our hospital. We divided the patients into two groups: normal chest radiograph (NCR) and abnormal chest radiograph (AbNCR), based on chest radiography findings. The incidence, clinical characteristics, and severity of AKI were compared between AKI and non- AKI groups according to the RIFLE classification.
Results:
Of the 467 patients, 96 (20.6%) constituted the AbNCR group. Compared with NCR patients, AbNCR patients were older (71 ± 11 vs. 62 ± 13 years, P < 0.001) and had higher total leukocyte counts (9.43 × 103/mL vs. 6.98 × 103/mL, P < 0.001). The AbNCR group had significantly longer duration of hospital stay (8.9 ± 5.5 vs. 6.3 ± 2.8 days, P < 0.001) and higher incidence of AKI (46.9% vs. 15.1%, P < 0.001). The common abnormal chest radiographic findings were pulmonary abnormalities, such as pulmonary congestion and pleural effusion. The overall AKI incidence was 21.6%, of which 12.4%, 7.9%, and 1.3% cases were classified as risk, injury, and failure, respectively. In a multivariable logistic regression analysis for association with AKI, old age, presence of chronic kidney disease or hypertension, leukocytosis, hypoalbuminemia, and chest radiographic abnormalities on admission were significant predictors of AKI.
Conclusion
Chest radiographic abnormalities on admission were independently associated with AKI in patients with scrub typhus.

Objectives:
On November 5, 2021, Pfizer Inc. announced Paxlovid (nirmatrelvir+ritonavir) as a treatment method that could reduce the risk of hospitalization or death for patients with confirmed coronavirus disease 2019 (COVID-19).
Methods:
From February 6, 2022 to April 2, 2022, the incidence of COVID-19 and the effects of treatment with Paxlovid were analyzed in 2,241 patients and workers at 5 long-term care facilities during the outbreak of the Omicron variant of severe acute respiratory syndrome coronavirus 2 in South Korea.
Results:
The rate of severe illness or death in the group given Paxlovid was 51% lower than that of the non-Paxlovid group (adjusted risk ratio [aRR], 0.49; 95% confidence interval [CI], 0.24−0.98). Compared to unvaccinated patients, patients who had completed 3 doses of the vaccine had a 71% reduced rate of severe illness or death (aRR, 0.29; 95% CI, 0.13−0.64) and a 65% reduced death rate (aRR, 0.35; 95% CI, 0.15−0.79).
Conclusion
Patients given Paxlovid showed a lower rate of severe illness or death and a lower fatality rate than those who did not receive Paxlovid. Patients who received 3 doses of the vaccine had a lower rate of severe illness or death and a lower fatality rate than the unvaccinated group.

BACKGROUND: Dysregulation of apoptosis plays an important role in carcinogenesis, tumor progression, and resistance to chemotherapy. X-linked inhibitor of apoptosis (XIAP) is considered to be the most potent caspase inhibitor of all known IAP (inhibitor of apoptosis) family members. This study was designed to assess the pattern of expression and the prognostic value of XIAP in radically resected non-small cell lung carcinoma (NSCLC) patients. METHOD: The expression of XIAP and its relationship with clinicopathologic parameters (patient age, TNM stage, TNM-pT, TNM-pN, histologic type, VEGF expression, microvessel density, PCNA index) and overall survival were analysed with formalin-fixed, paraffin-embedded blocks from eighty cases of NSCLC. In addition, the apoptotic index (AI) was also assessed. RESULTS: In a regard to histologic type, squamous cell carcinoma (SCC) showed XIAP expression in 91.3%(42/46) and adenocarcinoma (AC) in 61.8%(21/34). The difference was significant(p=0.001). There was no correlation between XIAP expression and other parameters. In the group of AC, XIAP expression showed the signifcant correlation with older age group > or = 58 years and VEGF expression(p=0.028, p=0.014, respectively). The AI in the group with or without XIAP expression were 2.5+/-4.9% and 18.5+/-28.9%, respectively(p=0.001). Both groups just aforementioned showed no significant difference in median survival time (42.5 months, 29.8 months, respectively). CONCLUSION: This study suggests that the XIAP expression in NSCLCs could have relation to inhibition of apoptosis, and show differential expression according to histologic type. However, its prognostic role during the progression of NSCLC needs to be further defined.

Choroidal metastasis from colorectal cancer is very rare and has not been reported before in Korea. We report a case of eye hyperemia and discomfort in a patient with advanced colon cancer. Orbit magnetic resonance imaging and positron emission tomography revealed an enhancing mass within the temporal side of the left orbit, suggestive of choroidal metastasis from the colorectal adenocarcinoma. The condition's rarity may be due to the long and distant pathway from the colon to the orbit. The presentation usually suggests extensive hematogeneous cancer dissemination and a poor prognosis. However, palliative radiotherapy may be an effective treatment for choroidal metastasis.
