End-of-life care needs for noncancer patients who want to die at home in South Korea.

AIM: The awareness for the need for end-of-life care has increased among noncancer patients. However, studies on the topic have rarely targeted the needs of noncancer patients who want to die at home. This study assessed the end-of-life care needs of noncancer patients who were receiving care and wanted to die at home. METHODS: A cross-sectional study design was used and involved 200 participants who were diagnosed as noncancer patients and receiving home care nursing. Data were collected on demographics, disease, Palliative Performance Scale (PPS) scores, and end-of-life care needs, in April and May, 2016. RESULTS: Among the six areas of care, "supporting fundamental needs" of patients required the most care, followed by "coordination among family or relatives." Multivariate analysis revealed that the duration of home care nursing held a significant association with end-of-life care needs. CONCLUSION: By reflecting on the comprehensive care needs of patients with chronic illnesses and including them in the care process, it will be possible to provide better quality palliative care to patients at home in the end-of-life stages.

Risk of Sarcopenia and Osteoporosis in Male Tuberculosis Survivors: Korea National Health and Nutrition Examination Survey.

Short-term prospective studies have suggested that pulmonary tuberculosis (TB) preludes permanent loss of lean tissue and fat mass even when TB treatment is effective. The aim of this study was to estimate the risk of sarcopenia and osteoporosis among Korean male TB survivors. Data of the population-based, Korea National Health and Nutrition Examination Survey (KNHANES) (2008-2011) were analyzed, including 3,228 males aged 50 years or older who underwent chest X-ray (CXR) and dual-energy x-ray absorptiometry (DEXA). TB survivors having both medical history and TB scars on CXR had increased risk of sarcopenia (odds ratio [OR] 3.44, 95% confidence interval [CI] 1.79-6.68) and osteoporosis (OR 1.75, 95% CI 1.04-2.95) after adjusting for age, height, smoking, alcohol, physical activity, serum 25-hydroxyvitamin D, parathyroid hormone level, education, and fat mass index. Having TB scars on CXR without medical history of TB was an independent risk factor of sarcopenia (OR 2.05, 95% CI 1.05-4.00), but not a risk factor of osteoporosis. Sarcopenia and low bone mineral density are prevalent in pulmonary TB survivors with TB scars on CXR. Medical history of TB with TB scars on CXR is an independent risk factor for sarcopenia and osteoporosis.

The Definition of Past Tuberculosis Affects the Magnitude of Association between Pulmonary Tuberculosis and Respiratory Dysfunction: Korea National Health and Nutrition Examination Survey, 2008-2012.

Tuberculosis (TB) is associated with an increased risk of chronic lung impairment. The aim of this study was to compare the clinical characteristics and lung functions according to definition of past TB. We used the population-based, Korea National Health and Nutrition Examination Survey (KNHANES) (2008-2012) to analyze 13,522 subjects age 40 years or older who underwent spirometry and chest X-ray (CXR). Subjects with TB lesions on CXR (with or without a history of TB) were older, more likely to be male, ever smokers, and of low socioeconomic status than subjects with only a history of TB or without evidence of TB. Airflow obstruction (AFO) was associated with only a history of TB (odds ratio [OR] 1.53, 95% confidence interval [CI] 0.95-2.46), only TB lesion on CXR (OR 2.37, 95% CI 1.80-3.12), and both a history and TB lesions on CXR (OR 4.47, 95% CI 3.07-6.51) after adjustment for gender, age, body mass index, education, income, and smoking amount (P for trend < 0.001). Spirometric restriction was associated with only a history of TB (OR 1.29, 95% CI 0.80-2.08), only TB lesions on CXR (OR 2.03, 95% CI 1.49-2.76), and both a history and TB lesions on CXR (OR 2.65, 95% CI 1.74-4.05) after adjustment for the above variables (P for trend < 0.001). How to define past TB in population study affects the magnitude of association between past TB and respiratory dysfunction. Without considering TB lesions on CXR, the association between TB and respiratory dysfunction could be underestimated.

Relationship between breast-feeding and bone mineral density among Korean women in the 2010 Korea National Health and Nutrition Examination Survey.

Breast-feeding has the deleterious effect of hypoestrogenemia coupled with loss of calcium in the maternal bone mass. It is not clear whether changes in bone metabolism in lactating women lead to changes in maternal bone mineral density (BMD) over a longer period. The aim of the present study was to investigate the relationship between the duration of breast-feeding and BMD in healthy South Korean women. We analyzed data from the 2010 Korea National Health and Nutrition Examination Survey, a cross-sectional survey of Korean citizens. A total of 1342 women older than 19 years were selected for analysis. In postmenopausal women, the duration of breast-feeding per child was associated with low lumbar spine BMD after adjustment for age, body mass index, smoking, alcohol intake, physical activity, serum 25-hydroxyvitamin D level, and daily intake of calcium and calories (P < 0.05, P trend < 0.005). Prolonged breast-feeding for more than 1 year per child was associated with a deleterious effect on lumbar spine BMD compared with never breast-feeding or a shorter duration of breast-feeding (P < 0.05). These effects were not shown in premenopausal women or in femur BMD. In conclusion, the duration of breast-feeding per child is negatively correlated with lumbar spine BMD in postmenopausal women, but not in premenopausal women. Although the cause of the different results between postmenopausal and premenopausal women is not clear, our findings suggest that proper protective strategies should be recommended during prolonged breast-feeding to maintain bone health later in life.

Association between the duration of palliative care service and survival in terminal cancer patients.

PURPOSE: Preliminary studies of early palliative care showed improved quality of life, less medical cost, and better survival time. But, most terminal cancer patients tend to be referred to palliative care late. For the proper care of terminal cancer patients, it is necessary to refer to hospice and palliative care timely. The aim of this study is to analyze the effect of the duration of palliative care services on the survival in terminal cancer patients. METHODS: We reviewed 609 patients who had died from terminal cancer between January 2010 and December 2012. We analyzed correlations of age, first Palliative Performance Scale (PPS) level, duration of palliative care service, and survival time. The Cox proportional hazards regression model was used for both univariate and multivariate analyses of survival. RESULTS: Duration of palliative care services was significantly correlated with survival time. In univariate Cox regression analysis, age, and each group of duration of palliative care service showed significant associations with survival. Final multivariate Cox regression model retained four parameters as independent prognostic factors for survival (age HR = 0.99 (p = 0.002), 1∼10 days HR = 2.64 (p < 0.001), 11∼30 days HR = 2.43 (p < 0.001), 31∼90 days HR = 1.87 (p < 0.001)). CONCLUSIONS: Shorter duration of palliative care services showed poor prognostic factor. Timely referral system from the end of chemotherapy is warranted.

The Association between Phase Angle of Bioelectrical Impedance Analysis and Survival Time in Advanced Cancer Patients: Preliminary Study.

BACKGROUND: A frequent manifestation of advanced cancer patients is malnutrition, which is correlated with poor prognosis and high mortality. Bioelectrical impedance analysis (BIA) is an easy-to-use and non-invasive technique to evaluate changes in body composition and nutritional status. We investigated BIA-derived phase angle as a prognostic indicator for survival in advanced cancer patients. METHODS: Twenty-eight patients treated at the hospice center of Seoul St. Mary's Hospital underwent BIA measurements from January, 2013 to May, 2013. We also evaluated palliative prognostic index (PPI) and palliative performance scale to compare with the prognostic value of phase angle. Cox's proportional hazard models were constructed to evaluate the prognostic effect of phase angle. The Kaplan Meier method was used to calculate survival. RESULTS: Using univariate Cox analysis, phase angle (hazard ratio [HR], 0.61/per degree increase; 95% confidence interval [CI], 0.42 to 0.89; P = 0.010), PPI (HR, 1.21; 95% CI, 1.00 to 1.47; P = 0.048) were found to be significantly associated with survival. Adjusting age, PPI, body mass index, phase angle significantly showed association with survival in multivariate analysis (HR, 0.64/per degree increase; 95% CI, 0.42 to 0.95; P = 0.028). Survival time of patients with phase angle ≥ 4.4° was longer than patients with phase angle < 4.4° (log rank, 6.208; P-value = 0.013). CONCLUSION: Our data suggest BIA-derived phase angle may serve as an independent prognostic indicator in advanced cancer patients.

The associations of epicardial adipose tissue with coronary artery disease and coronary atherosclerosis.

Epicardial adipose tissue (EAT) is presumed to play an important role in the development of coronary artery disease (CAD). The purpose of our study was to examine the influence of EAT volume measured by cardiac CT on the severity and presence of CAD. A total of 209 subjects (114 normal subjects and 95 patients with CAD) underwent cardiac and abdominal computed tomography (CT) scan before diagnostic coronary angiography. Pixels with a threshold range of -190 to -30 Hounsfield units were identified as EAT. CAGE ≥ 20, CAGE ≥ 50, and modified Gensini index were used to define the extent and severity of CAD. While there was no significant difference in BMI and WC between the two groups, the mean EAT volume was higher in the CAD group than in the normal subjects (102.4 ± 41.87 cm(3) versus 125.36 ± 47.64 cm(3), P < 0.001). EAT was significantly associated with CAGE ≥ 20, CAGE ≥ 50, and Gensini score by linear regression analyses after adjusting for age, gender, smoking, and alcohol use. The severity of CAD increased linearly with each tertile increase in EAT volume (P for trend < 0.05). Similarly, the coronary artery calcium (CAC) score was also increased with each increase in EAT tertile (P = 0.002). In multivariate logistic regression models, EAT and VAT were significantly associated with the presence of CAD and CAC in age, gender, smoking, alcohol use, and BMI adjusted models. In conclusion, EAT volume measured by CT is associated with the presence and severity of CAD. EAT may give important information for risk evaluation in CAD.
