RESUMEN

BACKGROUND: The quality of life of older adults deteriorates when they lose their ability to perform activities of daily living. Therefore, the older adults should be assessed to identify risk factors for functional decline and to correct these factors so that they may live as independently as possible in the community. We developed a medical care model using comprehensive geriatric assessment (CGA) for community-dwelling older patients. METHODS: Three hundred and ninety-one older adults who were frail or likely to be frail were selected. CGA was performed before and after the interventions to determine the effect of the interventions. Three interventions-exercise training, nutritional education, and medication reconciliation-were performed for 5.1 ± 0.6 months. RESULTS: A comparison of the results of the first and second assessments revealed that the participants showed improvement in physical function, quality of life, medication, and nutrition. The average gait speed had increased from 0.77 ± 0.17 m/s to 0.89 ± 0.20 m/s (P < 0.001). For health-related quality of life, the average EuroQol-5 dimension-3L score for each domain decreased significantly. The number of patients with polypharmacy decreased from 181(50 %) to 155(43 %) (P = 0.001). The number of patients who were at risk of malnutrition or malnourished decreased from 72(20 %) to 45(12 %) (P < 0.001). The majority of participants were highly satisfied and were willing to participate again. CONCLUSION: Our medical model based on CGA showed a significantly positive effect on the physical function and quality of life of community-dwelling older adults. Our model may be a promising strategy for improving the care of them.

RESUMEN

PURPOSE: Symptoms and discomfort are common complaints in primary care settings. It has been postulated that the physical symptoms are informative index in estimating Health-related quality of life (HRQOL). Thus, we conducted a community-based cross-sectional study to assess the relationship between somatic and psychological discomfort and HRQOL in elderly and non-elderly people. METHODS: A total of 2467 participants were recruited in 2013 from a population of 17,066 rural residents aged 20 or older. Information on demographic characteristics, somatic and psychological discomfort symptoms, and HRQOL was collected. Two months after the baseline survey, we conducted a repeated survey to assess changes in the discomfort symptoms and HRQOL. We evaluated associations of the discomfort symptoms with HRQOL using multiple linear regression and mixed model. RESULTS: EuroQol-Visual Analogue Scale (EQ-VAS), index of HRQOL, was correlated with fatigue, pain, sleep disturbances, indigestion, and anxiety/depression, after adjusting for covariates. However, the factors most significantly associated with EQ-VAS differed between the elderly and non-elderly. Pain was the most important factor contributing to EQ-VAS in the elderly, whereas depression and anxiety were the predominant factors in the non-elderly. These relationships were replicated in the repeated measurements to assess the change of symptoms and change of EQ-VAS. CONCLUSION: Our study suggests that somatic and psychological discomfort symptoms are associated with HRQOL. The main factors related to HRQOL vary according to age and large prospective studies and clinical trials are needed to clarify the association between specific symptoms and HRQOL according to the age.

RESUMEN

BACKGROUND & AIMS: To evaluate the relationship between phytoestrogen and colon cancer risk, we quantified plasma isoflavones (Genistein and Daidzein) and lignan (enterolactone) in a Korean nested case-control study and conducted replication study in a Vietnamese case-control study. METHODS: Study populations of 101 cases and 391 controls were selected from the Korean Multicenter Cancer Cohort which was constructed from 1993 to 2004. For replication study, Vietnamese hospital-based case-control subjects of 222 cases and 206 controls were selected from 2003 to 2007. The concentrations of plasma genistein, daidzein, and enterolactone were quantified by liquid chromatography-mass spectrometry. Logistic regression models were used to compute odds ratios (ORs) and 95% confidence intervals (CIs), and meta-analysis was conducted to estimate combined ORs (CORs) and 95% Cis of Korean and Vietnamese population in 2014. RESULTS: Genistein showed a continual decrease in colorectal cancer risk according to level up of the concentration categories in Korean and Vietnamese population (P for trend = 0.032, and 0.001, respectively) and a significantly decreased risk was found at the highest concentration of genistein and daidzein (for the highest category compared to the lowest: COR (95% CI) = 0.46 (0.30-0.69), and COR (95% CI) = 0.54 (0.36-0.82)). When the study population was stratified, the beneficial relationship of genistein with colorectal cancer was observed regardless of sex and anatomical subtype. However, enterolacton level was not associated with colorectal cancer risk. CONCLUSIONS: High plasma levels of isoflavones had relationship with a decreased risk of colorectal cancer, regardless of different ethnic background.

RESUMEN

BACKGROUND: This study aimed to estimate risk adjusted mortality rate in the ICUs (Intensive care units) by APACHE (Acute Physiology And Chronic Health Evaluation) III for revealing the performance variation in ICUs. METHODS: This study focused on 1,090 patients in the ICUs of 18 hospitals. For establishing risk adjusted mortality predictive model, logistic regression analysis was performed. APACHE III, surgery experience, admission route, and major disease categories were used as independent variables. The performance of each model was evaluated by c-statistic and goodness-of-fit test of Hosmer-Lemeshow. Using this predictive model, the performance of each ICU was tested as ratio of predictive mortality rate and observed mortality rate. RESULTS: The average observed mortality rate was 24.1%. The model including APACHE III score, admission route, and major disease categories was signified as the fittest one. After risk adjustment, the ratio of predictive mortality rate and observed mortality rate was distributed from 0.49 to 1.55. CONCLUSIONS: The variation in risk adjusted mortality among ICUs was wide. The effort to reduce this quality difference is needed.
