Background: Treatment of anemia is an important issue in the palliative care setting. Blood transfusion is generally used for this purpose in supportive care. However the place of blood transfusion in terminally ill cancer cases is less far established. Objective: We aimed to outline the use of transfusions and to find the impact of blood transfusion on survival in patients with advanced cancer and very near to death. Design: Patients dying in 2010-2011 with advanced cancer were included in the study. We retrospectively collected the data including age, type of cancer, the duration of last hospitalisation, ECOG performance status, Hb levels, transfusion history of erythrocytes and platelets, cause and the amount of transfusion. The anaemic patients who had transfusion at admission were compared with the group who were not transfused. Survival was defined as the time between the admission of last hospitalisation period and death. Results: Three hundred and ninety eight people with solid tumours died in 2010-2011 in our clinic. Ninety percent of the patients had anemia at the time of last hospitalisation. One hundred fifty three patients had erythrocyte transfusion at admission during the last hospitalisation period (38.4%). In the anaemic population the duration of last hospitalisation was longer in patients who had erythrocyte transfusion (15 days vs 8 days, p<0.001). Conclusions: Patients who had blood transfusion at the end of life lived significantly longer than the anaemic patients who were not transfused. This study remarks that blood transfusions should not be withheld from terminal cancer patients in palliative care.

This study was conducted to investigate the status of calcium intake and serum calcium level in perimenopausal women. The age distribution of the subjects was 49-55 years. Daily nutrient intake and dietary sources of calcium were analyzed by a convenient method and a food frequency questionnaire. At the same time, fasting blood samples were collected and serum calcium concentration was measured. The BMD of subjects was measured by Dual Energy X-ray Absorptiometry (DEXA). Fifty percent of the subjects under 50 years of age ($\leq$49 yr group) and 66.9% of the subjects from 50 years and up ($\geq$50 yr group) were classified as osteopenia or osteoporosis. Intake of energy (p<0.001), protein (p<0.05), fat (p<0.05), calcium (p<0.01) was significantly different between $\leq$49 yr group and $\geq$50 yr group. Mean daily intake of calcium was much lower than the Korean RDA : 94.9% in $\leq$49 yr group and 87.4% in $\geq$50 yr group. The average concentration of total calcium in serum was within the normal range in $\leq$49 yr group. Serum calcium concentrations were significantly (p<0.05) different between $\leq$49 yr group and $\geq$50 yr group. It was noteworthy that serum calcium concentration was positively related to the intake of protein, fat and calcium. Lettuce, sea mustard, bean-curd, anchovy, radish and perilla leaf was included among the major sources of dietary calcium. Further investigation is necessary to make sure of the relations between BMD and serum calcium level and calcium intake.

Background: The purpose of this study was to analyze the equality between key words used in the Journal of Korean Dental Society of Anesthesiology and Medical Subject Headings (MeSH). Methods: A total of 666 English key words in 187 papers (average 3.5 words in a paper) from 2001 to 2014 were eligible for this study. We classified them according to matched, and non-matched terms. After descriptive analysis, we assayed patterns of errors in using MeSH, and reviewed frequently used non-MeSH terms. Results: Fifty nine point six percent (59.6%) of total key words were completely coincident with MeSH terms, 40.39% were not MeSH terms. Conclusions: The results show that the coincidence rate of key words with MeSH terms was at a moderate level. However, there is a need for us to understand MeSH more specifically and accurately. Use of proper key words aligned with the international standards such as MeSH is important to be properly cited. The authors should pay attention and be educated on correct use of MeSH as key words.

Purpose: Fatigue is one of the most common complaints of cancer patients. In this study, we analyzed the change of fatigue level and general symptoms as time go by, so that, we could explain more on the mechanism and change of fatigue in relation with treatment, and explore the influencing factors. Method: The subjects of this study were 50 GI cancer patients who have visited the cancer center of A hospital in Suwon. We measured fatigue by using the Revised Piper Fatigue Scale(RPFS) at the time of starting and finishing induction chemotherapy, and starting the 2nd cycle of chemotherapy. Results: 1) The fatigue score was 2.81, 3.73, and 3.82 in a 10 point scale at the time of starting and finishing induction chemotherapy, and starting the 2nd chemotherapy, respectively. This means fatigue persisted until after the treatment. 2) Fifty two percent of participants complained of some kinds of symptoms when starting the treatment, and the proportion increased up to 92% when finishing the treatment. 3) Fatigue scores were significantly high in patients with fatigue-related symptoms than for patients without those symptoms. 4) Fatigue scores showed significant differences according to patients' general characteristics such as age, educational level, economic status, occupation, diagnosis, hematocrit, weight, and amount of sleepy. Conclusion: We have to develop intervention strategies to reduce fatigue in cancer patients in the consideration of influencing factors.

The purpose of this study was to investigate food sanitation status in elderly welfare facilities and assess the performance of food sanitation practices. Twenty elderly welfare facilities out of 85 located in Seoul with a capacity of fewer than 50 persons participated. The food sanitation status of worktable, kitchen utensils (knives, cutting boards, ladles, spoons), and tableware and bowls were examined by ATP bioluminescence. The results found that the ATP value of knife was the highest. Those of ladles appeared relatively higher than others. Meanwhile, the tableware and bowls, although washed everyday after meals, had the lowest ATP value. This study also conducted a survey on the food sanitation practices of 32 cooking employees in the 20 facilities. Fifty-six percent were in their 40s, and 53% had graduated from high school. More than half (66%) of them had no certification of cooking. Half of the respondents had worked for at least 5 years in food service facilities, and had received food sanitation training. Among them, 31% said they applied food sanitation training while working, and 47% responded the training was very helpful. The foodservice employees demonstrated good food sanitation practices. The results show that food sanitation performance of the workers significantly differed according to their age, education level, total work experience in food service facilities, chef certification, and prior food sanitation experience.
