Background: With increasing survival periods and diversification of treatment methods, treatment of critically ill cancer patients has become an important factor influencing patient prognosis. Patients with cancer are at high risk of infections and subsequent complications. This study investigated the incidence and factors contributing to the development of ventilator-associated pneumonia (VAP). Materials and Methods: This retrospective study investigated the incidence of VAP and factors leading to infection in patients admitted to the intensive care unit (ICU) of a cancer center from January 1, 2012 to December 31, 2013. Results: The incidence of VAP was 2.13 cases per 1,000 days of intubation, and 13 of 288 patients (4.5%) developed VAP. Lung cancer was the most common cancer associated with VAP (N=7, 53.9%), and longer hospital stays and intubation were associated with increased VAP incidence. In the group using a "ventilator bundle," the incidence was 1.14 cases per 1,000 days compared to 2.89 cases per 1,000 days without its use; however, this difference was not statistically significant (p=0.158). Age (${\geq}65$, OR=5.56, 95% confidence interval [CI]=1.29-23.95), surgery (OR=3.78, 95%CI=1.05-13.78), and tracheotomy (OR=4.46, 95%CI=1.00-19.85) were significant VAP risk factors. The most common causative organisms were methicillin-resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa (N=4, 30.8% each), followed by Acinetobacter baumannii and Candida albicans (N=2, 15.4% each). Conclusions: The incidence of pneumonia among critically ill cancer patients is highest in those with lung cancer, but lower than among non-cancer patients. The length of hospital stay and time on mechanical ventilation are important risk factors for development of VAP. Although not statistically significant, "ventilator bundle" care is an effective intervention that delays or reduces incidence of VAP. Major risk factors for VAP include age (${\geq}65$ years), surgery, and tracheostomy, while fungi, gram-negative bacteria, and multidrug-resistant organisms were identified as the major causative pathogens of VAP in this study.

Purpose: In this study analysis was done of utilization of rooming-in care in South Korean hospitals in order to examine the factors related to mothers and hospitals that affect rooming-in care. Methods: With the involvement of 254,414 mothers who gave birth across 953 hospitals, the analysis used the health insurance qualification data of the National Health Insurance Corporations and Health Insurance Review and Assessment Service (2006). Factors associated with rooming-in care were analyzed using a GEE logistic regression analysis to consider factors related to both mothers and hospitals. Results: Only 45.1% of the mothers used rooming-in care. The results of the regression analysis revealed that individual factors of the mothers were not associated with rooming-in care, whereas group factors of the hospitals were. Rooming-in care use was primarily related to small hospital, location of hospital, and higher nurse staffing level. Conclusion: The findings of this study indicate that the utilization of rooming-in care is not associated with factors an individual mother, but rather with the group factors of the hospitals. Thus, a policy-based approach considering both of these types of factors is required to enhance the utilization of rooming-in care.

This study aimed that certain risk factors are linked to the risk of developing depression and decreasing quality of life. This study was implemented using data from the 6th and 7th Korea National Health and Nutritional Examination Survey. The National Health and Nutrition Survey consist of health surveys, screenings, and nutrition surveys. Among the risk factors, data on adult diseases such as depression, hypertension, arthritis, diabetes, cataract, glaucoma, and macular degeneration were used. In total, 12,768 adults over 20 years of age were selected, of whom 520 were diagnosed with depression. The most common risk factors in adults over 20 years of age were hypertension, arthritis, cataract, diabetes, depression, glaucoma, and macular degeneration. Their risk factors were analyzed if these were associated with depression and quality of life. The results revealed that hypertension, arthritis, diabetes, cataract, glaucoma, and macular degeneration were predictors for the occurrence of depression in adults. The factors associated with the highest risk for depression were arthritis and glaucoma. Furthermore, the study investigated the effect of certain factors on the quality of life; the factor associated with the greatest impact on quality of life was arthritis. This study verified that the aforementioned factors were related to the risk of developing depression and decreasing quality of life.

Background: The risk factors of nocturia in older adults remain unclear. We aimed to investigate factors associated with nocturia using the National Health and Nutrition Examination Survey (NHANES) data. Methods: Among 40,790 participants, 4,698 participants aged ${\geq}65$ years were included from the NHANES dataset between 2005 and 2012. A multivariate logistic regression analysis was performed to determine the odds ratio (OR) for nocturia. A subgroup analysis was conducted based on sex and underlying diseases. Results: In the multivariate logistic regression model, obesity (OR, 1.46; 95% confidence interval [CI], 1.28-1.68), hypertension (OR, 1.28; 95% CI, 1.07-1.52), and diabetes mellitus (DM) (OR, 1.27; 95% CI, 1.11-1.45) were significantly associated with nocturia. These factors were associated with nocturia regardless of sex. In a subgroup of participants with hypertension, obesity (OR, 1.44; 95% CI, 1.25-1.67) and DM (OR, 1.26; 95% CI, 1.09-1.45) were associated with nocturia. In the additional analysis on patients with DM, nocturia was associated with obesity (OR, 1.33; 95% CI, 1.06-1.67) and duration of DM (OR, 1.02; 95% CI, 1.01-1.03). Conclusion: This study demonstrated that hypertension, DM, and obesity were significantly associated with the prevalence of nocturia in older adult patients regardless of sex. In particular, obesity was associated with nocturia in every subgroup analysis.

Weight gain is defined as the increase in body weight, increasing the prevalence of obesity, and results in metabolic diseases. Weight gain was reportedly caused by the interaction between the obesogenic environmental factors and individual metabolic factors. Sociodemographic and environmental factors (demographic factors, lifestyle/behavioral factors, food/nutritional factors, socioeconomic factors), drug-related secondary causes (some of the corticosteroids, antihyperglycemics, antihypertensives, antidepressants, etc.), and metabolic factors (aging and hormonal changes, menopause and decreased sex hormones, decreased adipocyte degradation, decreased fibroblast growth factor 21, central sympathetic nervous system hyperactivity, decreased sympathetic-adrenomedullary system activity) are significant factors related to weight gain. It is crucial to prevent weight gain and maintain an ideal weight, but studies on the risk factors of weight gain are insufficient. Therefore, this study evaluated the factors associated with weight gain to find strategies for preventing unnecessary weight gain.

Purpose: The purpose of this study is to identify the prevalence of the metabolic syndrome (MS) and factors associated with it among elders in a rural community. Methods: Data were collected from 683 subjects with a questionnaire, physical measurement, and blood test. The prevalence of the MS was determined by AHA/NHLBI and waist circumference cutoff points for Koreans. Results: The prevalence of the MS was 50.5% in total (41.6% in men, 56.3% in women) while the prevalence of 5 metabolic risk factors was 67.7% for elevated blood pressure, 51.0% for low HDL-cholesterol, and 50.2% for abdominal obesity. Risk factors associated with the prevalence of the MS included family history, BMI, and physical activity; significant factors associated with that of metabolic components included family history, BMI, smoking, drinking, and physical activity. Especially, a higher BMI was a strong risk factor of the prevalence of abdominal obesity as well as the MS and its components. Conclusion: The findings indicate that nurses should care for elders based on each metabolic component regarding its prevalence level and concentrate primarily on reducing elevated blood pressure, low HDL-cholesterol by controlling the main risk factor, abdominal obesity through lifestyle modification.

This study was conducted to define dietary patterns and to evaluate the effects of socioeconomic, acculturation and lifestyle factors on dietary patterns among 2,746 Korean- Americans in California. It was a cross-sectional telephone survey based on a representative sampling of individuals with a Korean surname using residential phone listings. It was conducted using a food frequency questionnaire that covered 20 food items, socioeconomic variables such as age, gender, income, education and acculturation, and lifestyle factors such as body weight, alcohol consumption, smoking, exercise and consumption of fast food. Four dietary patterns were identified: American Foods (AF), American Breakfast (AB), Korean Foods (KF) and Vegetables (Ⅴ). AF was associated with younger men, acculturation and fast food consumption. AB was associated with women, higher education, current smoking and fast food consumption. KF was associated with acculturation and lower socioeconomic status. Ⅴ was associated with lifestyle factors such as smoking, exercising and fast food consumption. The results of the study showed that socioeconomic and lifestyle factors influenced the dietary patterns of Korean- Americans. This should be considered when dietary interventions are designed for Korean-Americans to improve their health status.

Purpose: Purpose was to explore associations between sleep duration and metabolic syndrome (MS) risks, and to determine factors associated with self-rated health (SRH) of adults with MS compared to other adults. Methods: This is a secondary data analysis based on the Fifth Korea National Health and Nutrition Examination Survey KNHANES V (N=12662). Study instruments included sleep duration, MS risk factors, SRH and health-related quality of life (HRQoL). Results: Mean age of participants was $43.68{\pm}12.26years$. Fifty-eight percent were women, and 18.3% were identified as having MS. Systolic blood pressure (SBP), diastolic blood pressure (DBP), and SRH were significantly different according to sleep duration (p <.05) among all participants. In the non MS group, male gender, younger age (19~30 and 41~50 age brackets) upper income level, sufficient sleep duration, and high density lipoprotein (HDL) were positively associated with SRH, whereas, lower education levels (${\leq}$ middle school), glucose level, and waist circumference were negatively associated with SRH (p <.05). In the MS group, lower income, lower education levels (${\leq}$ middle school), glucose level, and waist circumference were negatively associated with SRH, whereas, having an occupation was positively associated with SRH (p <.05). Conclusion: Results suggest that tailored approaches are required for prevention and control of MS and sleep duration of each individual should be considered rather than applying standardized guidelines. However, as sleep quality was not included in the analysis, further investigations regarding influence of sleep quality on MS and SRH and controlling for other lifestyle and health behavior factors are required.

Background: This study aimed to analyze and describe the morbidity and mortality associated with tracheostomy in patients with oral cancer and to identify the risk factors associated with tracheostomy complications. Methods: We performed a retrospective chart review of patients who underwent tracheostomy during a major oral cancer resection between March 2001 and January 2016 at the National Cancer Center, Korea. Overall, we included 51 patients who underwent tracheostomy after oral cancer surgery. We assessed the morbidity and mortality of tracheostomy and determined the risks associated with tracheostomy complications. Results: Twenty-two tracheostomy-related complications occurred in 51 patients. The morbidity and mortality rates were 35.2 % (n = 18) and 0 % (n = 0), respectively. Tracheostomy-related complications were tracheitis (n = 4), obstructed tracheostomy (n = 9), displaced tracheostomy (n = 5), air leakage (n = 1), stomal dehiscence (n = 1), and decannulation failure (n = 2). Most complications (19/22) occurred during the early postoperative period. Considering the risk factors for tracheostomy complications, the type of tube used was associated with the occurrence of tracheitis (p < 0.05). Additionally, body mass index and smoking status were associated with tube displacement (p < 0.05). However, no risk factors were significantly associated with obstructed tracheostomy. Conclusions: Patients with risk factors for tracheostomy complications should be carefully observed during the early postoperative period by well-trained medical staff.

Stroke is a leading cause of death in the Korean population and remains a major health burden worldwide. The two main pathologic types of stroke are ischemic stroke and intracranial hemorrhage (ICH), but comparisons of risk factors for these have been limited. We under took a nationwide population-based study to analyze the relationship between these risk factor sand ischemic stroke and ICH. From January 2003 to December 2013, a total of 37,561 patients with newly diagnosed ischemic stroke or ICH were identified using the National Health Insurance Service data base as the study population. Multivariable logistic regression analysis was used to determine the association between baseline risk factors and presentation with ICH versus ischemic stroke. The incidence of ischemic stroke showed an increasing rend every year, while there was no significant change in the incidence of ICH. Of the several risk factors associated with stroke, old age (OR 2.35, 95% CI 2.12~2.49, P < 0.001) was more closely associated with ischemic stroke than ICH, whereas renal disease (OR 0.74, 95% CI 0.55~0.99, P = 0.04) and carotid disease (OR 0.25, 95% CI 0.17~0.35, P < 0.001) were more strongly associated with ICH. In addition, diabetes mellitus, dyslipidemia, hypertension, ischemic heart disease and male sex was associated with an increased risk of ischemic stroke. Old age was more strongly associated with ischemic stroke than ICH, while carotid stenosis and renal impairment were more closely associated with ICH risk. Classic risk factors for stroke have considerably different associations with the two main pathologic types of stroke.
