PURPOSE: The purpose of this study was to find factors affecting hospital nurses' cancer prevention health promoting behavior METHODS: The subjects were 308 nurses working in general hospitals with over 300 beds. Knowledge of cancer was assessed with 36 question items for six major cancers, and the attitude toward cancer was assessed with 10 items for cancer prevention and early detection. Cancer prevention health promotion behavior was assessed by 21 questions about diet, health life, and exercise. The collected data were analyzed using frequency and percentage, t-tests, one-way ANOVA, Pearson correlation coefficients, and stepwise multiple regression analysis. RESULTS: The score for knowledge of cancer was 25.12±3.33. The average score for attitude towards cancer was 30.41±4.08. The score of cancer prevention health promoting behaviors on cancer was 70.60±10.90. Cancer prevention health promoting behaviors were not correlated with cancer knowledge, and were positively correlated with cancer attitude (r=0.44, p < .001). There was a positive correlation with the cancer prevention attitude (r=0.49, p < .001) among the sub-areas of cancer attitude. CONCLUSION: The nurses' knowledge, attitude, and preventive health promotion behaviors of cancer were important for the health of individuals, patients and the general public, I think it is necessary to search for ways to actively promote cancer prevention health promoting behaviors in various directions and to confirm their effects.

BACKGROUND/OBJECTIVES: Nutritional status and food intake during pregnancy and lactation can affect fetal programming. In the current metabolic syndrome epidemic, highfructose diets have been strongly implicated. This study investigated the effect of maternal high-fructose intake during pregnancy and lactation on the development of metabolic syndrome in adult offspring. SUBJECTS/METHODS: Drinking water with or without 20% fructose was administered to female C57BL/6J mice over the course of their pregnancy and lactation periods. After weaning, pups ate regular chow. Accu-Chek Performa was used to measure glucose levels, and a tail-cuff method was used to examine systolic blood pressure. Animals were sacrificed at 7 months, their livers were excised, and sections were stained with Oil Red O and hematoxylin and eosin (H&E) staining. Kidneys were collected for gene expression analysis using quantitative real-time Polymerase chain reaction. RESULTS: Adult offspring exposed to maternal high-fructose intake during pregnancy and lactation presented with heavier body weights, fattier livers, and broader areas under the curve in glucose tolerance test values than control offspring. Serum levels of alanine aminotransferase, aspartate aminotransferase, glucose, triglycerides, and total cholesterol and systolic blood pressure in the maternal high-fructose group were higher than that in controls. However, there were no significant differences in mRNA expressions of reninangiotensin-aldosterone system genes and sodium transporter genes. CONCLUSIONS These results suggest that maternal high-fructose intake during pregnancy and lactation induces metabolic syndrome with hyperglycemia, hypertension, and dyslipidemia in adult offspring.

Brain metastasis affects one third of patients with HER2-positive breast cancer after treatment with trastuzumab. Surgical resection and radiation therapy are often unsuccessful at accomplishing complete control of metastasis. Lapatinib is presumed to cross the blood-brain barrier, and exhibits clinical activities for treatment of HER2-positive breast cancer. A 43-year-old woman was treated for early breast carcinoma with total mastectomy, axillary lymph-node dissection, and adjuvant chemotherapy with cyclophosphamide plus doxorubicin. After the end of adjuvant trastuzumab therapy, she was diagnosed with panhypopituitarism due to pituitary metastasis. Surgical removal and whole brain radiation therapy were performed, but a portion of viable tumor remained. Only taking lapatinib, the size of the metastatic lesion began to shrink. Trastuzumab may have controlled the micro-metastasis of breast cancer, but it was unable to control its progression to the central nervous system. Lapatinib is a possible option for HER2-positive metastatic breast cancer patients with brain metastasis.

OBJECTIVES: To evaluate the inhibitory effect of ursolic acid (UA)-containing composites on Streptococcus mutans (S. mutans) biofilm. MATERIALS AND METHODS: Composite resins with five different concentrations (0.04, 0.1, 0.2, 0.5, and 1.0 wt%) of UA (U6753, Sigma Aldrich) were prepared, and their flexural strengths were measured according to ISO 4049. To evaluate the effect of carbohydrate source on biofilm formation, either glucose or sucrose was used as a nutrient source, and to investigate the effect of saliva treatment, the specimen were treated with either unstimulated whole saliva or phosphate-buffered saline (PBS). For biofilm assay, composite disks were transferred to S. mutans suspension and incubated for 24 hr. Afterwards, the specimens were rinsed with PBS and sonicated. The colony forming units (CFU) of the disrupted biofilm cultures were enumerated. For growth inhibition test, the composites were placed on a polystyrene well cluster, and S. mutans suspension was inoculated. The optical density at 600 nm (OD600) was recorded by Infinite F200 pro apparatus (TECAN). One-way ANOVA and two-way ANOVA followed by Bonferroni correction were used for the data analyses. RESULTS: The flexural strength values did not show significant difference at any concentration (p > 0.01). In biofilm assay, the CFU score decreased as the concentration of UA increased. The influence of saliva pretreatment was conflicting. The sucrose groups exhibited higher CFU score than glucose group (p < 0.05). In bacterial growth inhibition test, all experimental groups containing UA resulted in complete inhibition. CONCLUSIONS: Within the limitations of the experiments, UA included in the composite showed inhibitory effect on S. mutans biofilm formation and growth.

PURPOSE: A population-based study was conducted in order to examine the characteristics of family members of cancer patients in comparison with the general population and also to evaluate the psychosocial impact of cancer patients on their family members. MATERIALS AND METHODS: From the Fourth Korea National Health and Nutrition Examination Surveys (KNHANES IV) (2007-2009) dataset, we identified 460 cancer patients and then selected family members of these patients who were aged 20 years or older (n=565). The control group was sampled from members of families without a cancer patient with matching for sex and age (n=2,260). Serial conditional logistic regression models were used for comparison of characteristics between family members of cancer patients and subjects in the control group. RESULTS: Family members of cancer patients were less employed (57.9% vs. 63.0%, p<0.001), more functionally limited (20.2% vs. 16.5%, p=0.032), and had lower self-rated health (p=0.023) compared with sex and age-matched control subjects. They also had a significantly higher level of stress (79.7% vs. 76.1%, p=0.008), history of depression (12.9% vs. 10.2%, p=0.035), and current depressive symptoms (5.5% vs. 3.5%, p=0.038). However, higher physical activity was reported in family members of cancer patients (13.6% vs. 9.6%, p=0.003) than in control subjects. The presence of a cancer patient in the family showed an association with current depressive symptoms (odds ratio, 1.62; 95% confidence interval, 1.05 to 2.48; p=0.028), however, the association was no longer significant after adjustment for household income, education level, and employment status (p=0.304). CONCLUSION: Family members of cancer patients are more susceptible to depression, probably due to adverse change in socioeconomic status. Use of multidisciplinary approaches for promotion of psychological health and well-being is essential.

Purpose: The aim of this study was to evaluate the episodes of febrile neutropenia (FN) in patients with gastric cancer (GC), colorectal cancer (CRC), lung cancer (LC), and breast cancer (BC); and to identify the incidence and trends of admission rates, as well as factors affecting mortality. Materials and Methods: Using nationwide claims data, all new admissions to hospitals for FN were selected. We evaluated the incidence of FN and mortality-related clinical factors in adult cancer patients who received cytotoxic chemotherapy from January 2004 to December 2013. Results: While the incidence of FN increased, the length of hospitalization decreased in Korea. The incidence of FN was 19.8% in LC patients, 15.5% in GC patients, 13.3% in BC patients, and 9.5% in CRC patients. The overall in-hospital mortality of FN was 12.9% and showed a decreasing trend. Admission rates to intensive care units and in-hospital mortality were the highest for lung cancer (15.2% and 19.3%, respectively). Age and sepsis syndrome were risk factors for in-hospital mortality for all cancer types. Conclusion Careful observation and active prophylaxis should be considered for patients at high risk of FN.

Purpose: This study aims to explore income-based disparities in breast cancer (BC) incidence and stage at presentation in a national population in South Korea, where a National Cancer Screening Program (NCSP) has been implemented. Methods: In 2007, new patients with BC were identified using the Korea Central Cancer Registry database. We calculated adjusted odds ratios (aORs) to evaluate the association between individual income level and the risk of distant stage BC at presentation, adjusting for women’s age, body mass index, disability registration, employment, region of residence, and year of diagnosis. Results: The cumulative age-standardized incidence of BC in the 11 years was highest among women in the richest quintile (2,040 per 100,000 women for 11 years), whereas the proportion of distant stage at presentation was the highest (10.2%) among the medical aid beneficiaries. The aOR of distant stage diagnosis at presentation was higher for lowerincome quintiles, and the risk was the highest in the medical aid beneficiaries (aOR, 2.25;95% confidence interval, 1.97–2.58) than in the richest quintile. The income-based gradient in aORs for distant stage did not differ between younger (< 40 years) and older patients. Conclusion A higher risk of distant stage BC at presentation among the lower-income and medical aid groups in the context of a NCSP was observed. A more focused approach toward women in lower-income groups is necessary to alleviate the disparity in the risk of advanced BC.

Purpose: Cancer patients receiving various anti-cancer treatments commonly experience malnutrition, and many studies have reported that nutritional status is associated with survival and prognosis. Although standard neoadjuvant chemoradiotherapy (CRT) is commonly used in patients with locally advanced rectal cancer owing to its tumor-downsizing and downstaging effects, there is a lack of research on the impact of patients’ nutritional status on the efficacy of neoadjuvant CRT. Methods: We investigated the immunonutritional markers before and after long-course neoadjuvant CRT in 131 patients diagnosed with locally advanced rectal cancer from March 2013 to March 2022. Results: We divided the patients into two groups: a low prognostic nutritional index (PNI) with a cutoff value of 50.92, and a high PNI. In both groups, significant decreases in lymphocyte count and PNI and an increase in neutrophil-to-lymphocyte ratio (NLR) were observed before and after CRT (P<0.001). Furthermore, a higher proportion of patients experienced adverse effects in the low PNI group than in the high PNI group (76.6% in low PNI vs. 54.8% in high PNI, P=0.013). The most commonly reported CRT-induced adverse effect was lower gastrointestinal tract toxicity. Conclusion By measuring the PNI and NLR without additional tests prior to starting neoadjuvant CRT in patients with locally advanced rectal cancer, it is possible to predict the risk of acute adverse effects caused by CRT. Additionally, providing external nutritional support to reduce the immunonutritional changes that occur during CRT can decrease side effects and potentially increase treatment compliance.
