Journal of Korean Academy of Psychiatric and Mental Health Nursing 2016;25(3):195-206
PURPOSE: This study was done to explore the experience process for depression in elderly women living alone. METHODS: Data was analyzed using Strauss and Corbin's Grounded theory. The twelve participants were elderly women living alone, aged 65 to 80 years. RESULTS: From the participants' statements, 116 concepts, 43 sub-categories and 16 categories were extracted by an open coding process. Core category was 'wandering in a waste land'. The experience process leading to depression in elderly women living alone had 4 phases: loss, emptiness, struggle and response. CONCLUSION: The findings in this study on the experience of depression in elderly women living alone can be used for evidence in a detailed assessment, early detection and prevention of depression in elderly women living alone.

2.The Factors Influencing Meal Satisfaction in Older Adults: A Systematic Review and Meta-analysis
Asian Nursing Research 2019;13(3):169-176
PURPOSE: The aim of this study was to identify factors influencing meal satisfaction in older adults. METHODS: Authors searched four databases Ovid MEDLINE, Ovid EMBASE, the Cochrane Library, and KoreaMed using the following key search terms: “(elderly-mp. OR aged), AND (meal OR food OR eating OR feeding), AND satisfaction.” Only articles published between January 1946 and May 2018 were considered. The preferred reporting items for systematic reviews and meta-analyses guidelines were adopted for quality assessment. The authors ultimately selected 7 of 1,695 references for review and meta-analysis. RESULTS: A meta-analysis was conducted to determine the factors influencing meal satisfaction in older adults aged more than 60 years. The results showed that meal satisfaction was low when age increased and the individual was served frozen meals. Satisfaction with meals was high when food choices were available and individuals were served high-quality food and when the food smelled and tasted good or was personally tailored. Satisfaction was also high when individuals ate with their families. Moreover, meal satisfaction seemed to be influenced by physical health, whereas it did not show a significant correlation with mental health. CONCLUSION: Intending to improve the quality of life of older adults by increasing their meal satisfaction, the authors pointed out factors that institutions should attend to when providing meals to older adults. To contribute to the lack of any existing conceptual and theoretical framework in this field, further steps to be taken by the authors shall involve concept analysis that would assist in building a conceptual framework.

3.Factors Influencing the Fear of Falling in Elderly in Rural Communities.
Journal of Agricultural Medicine & Community Health 2011;36(4):251-263
OBJECTIVES: The purpose of this study was to examine the factors associated with fear of falling among the elderly dwelling in rural communities. METHODS: From February 1, 2010 to March 31, 2010, a questionnaire-based survey was sent to 2,628 persons 65 years or older dwelling in 1 Myeon and 1 Eup of Gyeongsangnam-do. Among these participants, 735 (27.9%) had fallen more than once in 2009. For data analysis, descriptive statistics and hierarchical multiple regression were performed using SPSS version 12.0. RESULTS: Factors influencing the fear of falling in the elderly according to falls experienced were number of outpatient visits, number of falls, gender, admission, purchasing of health function foods, and activities of daily living. Overall, the study showed significant differences in the score of fear of falling according to gender, age, education, marital status, living arrangement, main means of mobilization, drinking, income, number of falls, admission, number of outpatient visits, experience with outpatient oriental medicine, purchasing of health function foods, medical assistance devices, season, fall location, fall cause, shoe type, injury type, limitation of activity, and activities of daily living. CONCLUSIONS: The results of this study suggest that programs should be developed specifically for elderly people who have experienced more than one fall because of increased fear due to multiple falls.

4.Effect of Puffing in the Extraction of Active Ingredients from the Roots of Paeonia lactiflora and Astragalus membranaceus
Natural Product Sciences 2022;28(2):89-92
In Asia, the roots of Paeonia lactiflora and Astragalus membranaceus have been used as therapeutic agents for thousands of years. Once the medicinal plants are harvested, they are dried and their ingredients are extracted by heat-mediated reflux extraction. However, the condensed structure of organic products (especially roots) limits the extraction of bioactive components. In this study, we assessed the effect of the puffing method (using high temperature and pressure) before the extraction process in relation to the profile and antioxidant capacity of active ingredients. We demonstrated that the additional puffing process before extraction methods improves the yield of polyphenol concentrations and antioxidant activities from the roots of P. lactiflora and A.membranaceus.

BACKGROUND: The accumulation of lipoprotein and monocyte in the intima of the arterial wall is the most important step of the development of coronary artery disease (CAD). Lipoprotein lipase (LPL) plays an anti-atherogenic role by lipolysis of triglyceride-rich lipoproteins, but, it may also act as a receptor of some lipoproteins and monocyte at the arterial wall and act as a atherogenic molecule. Previous studies showed somewhat contradictory results about the association of CAD and LPL polymorphisms and mutations. Racial and dietary difference may contribute to these contradictory results. In this study, we tried to find out the association of CAD and the genetic variation of the LPL (PvuII RFLP in intron 6, HindIII RFLP in intron 8 and Ser 447 Ter mutation in exon 9) in Korean population. METHOD AND RESULT: CAD patients (n=146), confirmed by coronary angiography and healthy Korean adult volunteers (n=110) were genotyped for PvuII/HindIII RFLP and Ser447Ter mutation of the LPL gene by PCR-digestion method. Between two groups, the genotype frequency of these genetic variations was not different. But, the genetic variations showed different effect on lipid profile and body mass index (BMI) in the CAD group and in the control group. In the CAD group, P1 allele carriers showed higher total cholesterol (P1P1+P1P2:P2P2=216+-51 mg/dl:198+/-38 mg/dl, p=0.039) and higher LDL cholesterol level (P1P1+P1P2:P2P2=143+/-46 mg/dl:126+/-36 mg/dl, p=0.047), and H1 allele carriers had lower Body mass index than non-carriers (23.8+/-2.3 kg/m2 :24.8+/-2.9 kg/m2 , p=0.047). In the control group, the Ser447Ter mutation carriers had higher HDL cholesterol level than non-carriers (59+/-10mg/dl versus 53+/-11mg/dl, p=0.049) and patients with P1 allele showed lower body mass index (P1P1+P1P2: P2P2=23.1+/-2.6 kg/m 2 :24.5+/-2.6 kg/m2 , p=0.006). CONCLUSION: In Korean, PvuII/HindIII RFLP and Ser447Ter mutation was not associated with CAD, and they showed different effect on the lipid profile and on the body mass index according to the study group. These results suggests that the phenotypic characteristics of the LPL gene of the Korean people are different from those of occidental people.

BACKGROUND: Red blood cell (RBC) transfusion is one of the major treatments for correcting anemia, but its use should be carefully considered because of adverse transfusion reactions and inappropriate usage. Therefore, individual health care facilities have self evaluated their use of transfusion in an attempt to decrease unnecessary procedures. In this study, we evaluated the differences in the minimum hemoglobin (Hb) trigger for RBC transfusion among clinical departments in Severance Hospital. METHODS: We analyzed the electronic medical records of RBC transfusion episodes that were conducted at a Hb level above 8 g/dL from July 2014 to September 2015. We classified these data by clinical department, and considered the overall medical conditions of the patients. The minimum Hb trigger level in this study was defined as the lowest Hb level within 24 hours prior to RBC transfusion. RESULTS: A total of 4,953 RBC transfusion episodes that were conducted at Hb levels above 8 g/dL were analyzed over that period. In general, the minimum Hb trigger level was higher in the operation group than the hemorrhage group. When compared among clinical departments, the department of orthopedic surgery, neurosurgery, rehabilitation medicine, and anesthesiology showed high levels of minimum Hb trigger equal to or greater than 10 g/dL. CONCLUSION: The minimum Hb trigger level differed among clinical departments, with the operation group showing a much higher level of minimum Hb trigger. We hope that these data will be practically applied to establish plans and strategies for managing the appropriateness of RBC transfusions in Korea. In addition, continuous evaluation and transfusion education for clinical departments should be performed.

OBJECTIVES: This study aimed to confirm the efficacy of the urinary fluoride concentration/creatinine ratio for monitoring fluorine intake in fluoridated and non-fluoridated communities. METHODS: The correlations among the fluoride concentration in drinking water and that in the urine and fingernails of 52 preschool children (age, 60-72 months) from fluoridated and non-fluoridated communities were analyzed. RESULTS: The urinary fluoride concentration/creatinine ratio had a relatively high correlation with the fluoride concentration in drinking water (Pearson's correlation coefficient, 0.606; P<0.05). Further, this ratio was significantly positively correlated with the urinary fluoride concentration (Pearson's correlation coefficient, 0.374; P<0.01). However, there was no significant correlation between this ratio and the fluoride concentration in fingernails (Pearson's correlation coefficient, 0.145; P>0.05). CONCLUSIONS: The findings of this study suggest that the urinary fluoride concentration/creatinine ratio in children can be utilized as an index for monitoring excess fluoride intake in fluoridated communities.

Annals of Clinical Microbiology 2020;23(3):185-194
Background:
The rapid antimicrobial susceptibility testing (AST) performed on urine samples would guide the adequate choice of antibiotics for obtaining better treatment outcomes in patients. Our study aimed to evaluate the performance of the modified-EUCAST (European Committee on Antimicrobial Susceptibility Testing) rapid direct AST on urine samples.
Methods:
From >2,000 urine samples, a total of 128 urine samples containing bacterial counts of ≥2 × 10 4 CFU/mL with a uniform bacterial shape were initially included based on flow cytometry (Sysmex UF-1000i, Japan) and Gram staining, respectively. A total of 103 samples showing the presence of Enterobacteriaceae were finally selected in this study. The urine samples were directly inoculated on Mueller-Hinton agar, which was used in the current EUCAST rapid direct AST on blood samples. The size of the growth inhibition zones around antimicrobial disks was measured using a digital scanner (BIOMIC vision analyzer, Giles scientific, USA) and further confirmed by visualization with naked eyes after incubation for 4, 6, and 8 hours. The AST interpretations were compared to those of the conventional VITEK 2 AST system (bioMérieux, France) and the discrepancies between both tests were confirmed with the E-test.
Results:
The antibiotics, namely ampicillin, cefazolin, aztreonam, ceftazidime, cefotaxime, cefoxitin, cefepime, gentamicin, ciprofloxacin, and cotrimoxazole showed excellent correlations with modified-EUCAST rapid direct test and conventional ASTs with >0.75 weighted kappa values. The categorical agreement of the rapid direct AST was 1,442 (93.3%), with 76 (4.9%) minor error, 9 (0.6%) major error and 18 (1.2%) very major error, implicating the reliability of this method for clinical application.
Conclusion
Performing the modified-EUCAST rapid direct AST on urine samples can predict reliable AST results within 8 hours. The rapid direct AST can help the physicians to initiate adequate antimicrobial treatment for urinary tract infections.
