Experience of Violence and Hospital Violence Attitude according to Gender and Gender-Role Identity of Clinical Nurses / 한국직업건강간호학회지

Purpose@#This study aims to examine differences in experiences of violence and hospital violence attitude according to gender and gender-role identity of clinical nurses. @*Methods@#The quota sampling method, was used to select the research subjects. They were divided into two groups male and female nurses who worked for three general hospitals or higher level-hospitals in Incheon and Gyeongbuk. The data of 219 subjects was used for final analysis. The IBM SPSS 22.0 was used to analyze the data t-test and ANOVA. @*Results@#According to gender, the hospital violence experience of female nurses was oserved frequently when the verbal violence came from guardians, and when the physical threats came from others. For male nurses, the experiences of hospital violence was obserbed. According to gender, the hospital violence attitude revealed significant differences in female nurses that the negative attitude was higher (t=-4.69, p<.001). According to gender-role identity, the undifferentiated and femininity showed significant differences (F=4.86 p=.003). @*Conclusion@#The differentiated strategies of coping measures and violence preventive education considering the gender and gender-role identity of clinical nurses would help formulate measures for the effective management of hospital violence.

Development of a Label-Free LC-MS/MS-Based Glucosylceramide Synthase Assay and Its Application to Inhibitors Screening for Ceramide-Related Diseases

Ceramide metabolism is known to be an essential etiology for various diseases, such as atopic dermatitis and Gaucher disease. Glucosylceramide synthase (GCS) is a key enzyme for the synthesis of glucosylceramide (GlcCer), which is a main ceramide metabolism pathway in mammalian cells. In this article, we developed a liquid chromatography-tandem mass spectrometry (LC-MS/MS) method to determine GCS activity using synthetic non-natural sphingolipid C8-ceramide as a substrate. The reaction products, C8-GlcCer for GCS, could be separated on a C18 column by reverse-phase high-performance liquid chromatography (HPLC). Quantification was conducted using the multiple reaction monitoring (MRM) mode to monitor the precursor-to-product ion transitions of m/z 588.6 → 264.4 for C8-GlcCer at positive ionization mode. The calibration curve was established over the range of 0.625–160 ng/mL, and the correlation coefficient was larger than 0.999. This method was successfully applied to detect GCS in the human hepatocellular carcinoma cell line (HepG2 cells) and mouse peripheral blood mononuclear cells. We also evaluated the inhibition degree of a known GCS inhibitor 1-phenyl-2-decanoylamino-3-morpholino-1-propanol (PDMP) on GCS enzymatic activity and proved that this method could be successfully applied to GCS inhibitor screening of preventive and therapeutic drugs for ceramide metabolism diseases, such as atopic dermatitis and Gaucher disease.

Factors Affecting Food Carving among Hemodialysis Patients / 임상간호연구

PURPOSE: The purpose of this study was to evaluate food carving among hemodialysis patients and to identify factors affecting the food carving. METHODS: hemodialysis between March 15 and April 15, 2017. Measurement instruments included the general food craving questionnaire trait, the center for epidemiological studiesdepression scale, and stress response inventory-modified form. The statistical analysis included t-test, analysis of variance, pearson correlation analysis, and stepwise multiple regression analysis. RESULTS: Mean food craving score was 53.00±12.36. Food craving was higher in patients younger than 40 years (F=4.36 p=.006) and having occupation (t=2.18 p=.031). Patients receiving hemodialysis demonstrated higher levels of depression (21.37±9.62) and stress (39.68±15.95). Factors influencing food craving were depression (β=.52, p<.001), stress (β=.65, p<.001), and age 50~59 years old (β=−.28, p=.001) and 60~69 years old (β=−.19, p=.026), which accounted for 25.6% of total variance. CONCLUSION: Food craving among hemodialysis patients was influenced by patients' depression, stress and age. Assessment and management of depression and stress needs to be incorporated as a nursing strategy for dietary management for hemodialysis patients.

The effect of nutritional supply on clinical outcomes and nutritional status in critically ill patients receiving continuous renal replacement therapy / 한국영양학회지

PURPOSE: This study was designed to investigate whether nutritional supply influences biochemical markers and clinical outcomes in patients who received continuous renal replacement therapy (CRRT) by evaluating adequacy of nutritional supply for patients. METHODS: From January 2012 to December 2013, 239 adult patients who received CRRT in the intensive care unit for more than 3 days were included. General information from electronic medical records and nutritional status related biochemical data and clinical outcomes on the first day of CRRT and 2 weeks after CRRT were collected. RESULTS: The rate of delivered energy and protein was 68.06% and 43.13% which was much lower than energy and protein supply based on their requirement. When the patients were divided into two groups according to 70% of energy received rate and 50% of protein received rate, the group with more than 70% of energy received rate showed significant decrease of length of hospital stay (p = 0.007), length of stay in intensive care unit (ICU) (p = 0.008), duration of CRRT (p < 0.001), and APACHE II score (p < 0.001) compared to less than 70% of energy received rate after adjusting for age. In addition, the group with more than 50% of protein received rate showed decreased mortality (p = 0.031), length of hospital stay (p = 0.008), length of ICU stay (p = 0.035), duration of CRRT (p < 0.001), and APACHE II score (p < 0.001) after adjusting for age. We found that the level of hematocrit (p = 0.006) was significantly improved in the group with more than 70% of energy received rate, and the level of TLC (p = 0.049), hematocrit (p = 0.041) was significantly improved in the group with more than 50% of protein received rate. We also found that energy delivery was negatively correlated with length of stay in ICU (p = 0.049) and positively correlated with level of calcium (p = 0.037). In addition, protein delivery was correlated with the levels of serum total protein (p = 0.021), serum albumin (p = 0.048), hematocrit (p = 0.009), and total cholesterol (p = 0.021) when dead patients were included, but was correlated with the levels of hematocrit (p = 0.034) and calcium (p = 0.024) when dead patients were excluded. CONCLUSION: Proper nutritional delivery may help patients' clinical outcomes for patients receiving CRRT. However, their actual intakes of energy and protein were not adequate for their requirements. Identification of patients with malnutrition is necessary and a multidisciplinary approach for systemic management is also required.

Risk Factors and Features of Critically Ill Patients with Deep Vein Thrombosis in Lower Extremities

PURPOSE: The purpose of this study was to identify the features, risk scores and risk factors for deep vein thrombosis in critically ill patients who developed deep vein thrombosis in their lower extremities. METHODS: The participants in this prospective descriptive study were 175 adult patients who did not receive any prophylactic medication or mechanical therapy during their admission in the intensive care unit. RESULTS: The mean age was 62.24 (+/-17.28) years. Men made up 54.9% of the participating patients. There were significant differences in age, body mass index, and leg swelling between patients who developed deep vein thrombosis and those who did not have deep vein thrombosis. The mean risk score was 6.71(+/-2.94) and they had on average 4.01(+/-1.35) risk factors. In the multiple logistic regression, body mass index (odds ratio=1.14) and leg swelling (odds ratio=6.05) were significant predictors of deep vein thrombosis. CONCLUSION: Most critically ill patients are in the potentially high risk group for deep vein thrombosis. However, patients who are elderly, obese or have leg edema should be closely assessed and more than one type of active prophylactic intervention should be provided.

Factors Related to Fall in Elderly Patients with Osteoporosis / 성인간호학회지

PURPOSE: The purpose of this study was to identify risk factors of fall and to examine its results among patients aged 60 and over diagnosed with osteoporosis. METHODS: A retrospective descriptive survey was conducted with 91 patients admitted in a university hospital in a city. Data were collected using an interview method with a structured questionnaire, and were analyzed using descriptive statistics and multiple logistic regression. RESULTS: In patients with osteoporosis, the intrinsic risk factors of falls were aging (OR = 3.742), gait disturbance (OR = 12.565), taking one or fewer medicine (OR = 7.873), and having two or more diseases (OR = 5.173). The extrinsic risk factors included the use of a bed (OR = 3.093), slippery floors (OR = 12.130), bathroom mat without anti-slip rubber backing (OR = 3.564), and presence of a night light on the passage from the bedroom to the bathroom (OR = 2.980). CONCLUSION: For the elderly aged over 70 who are most vulnerable to falls, screening tests such as bone mineral density (BMD) should be conducted in health examinations and the risk of fracture caused by osteoporosis should be communicated to the vulnerable elderly. Besides, development of new exercise programs combining weightbearing exercise is needed to prevent bone loss and increase functional activities.

Clinical Experiences of Management of Bile Duct Injuries during Laparoscopic Cholecystectomy

PURPOSE: Laparoscopic cholecystectomy (LC) has become the gold standard of management of gallstone disease. LC is associated with a two-to-four times higher incidence of bile duct injury, which is a rare but more serious complication than open cholecystectomy. We reviewed our experiences with the management of bile duct injury during laparoscopic cholecystectomy. METHODS: From January 1999 to April 2009, 13 patients with bile duct injuries following LC were managed in our hospital. Patients' charts were retrospectively reviewed to analyze perioperative management. RESULTS: Among the 13 patients, 7 patients sustained their bile duct injuries at our hospital. Six patients were referred to our hospital to manage their bile duct injuries. Five patients' injuries were identified during LC. According to the Strasberg classification, there are 5 cases of type A, 2 cases of type C, 1 case of type D and 5 cases of type E injuries. Four type A bile duct injuries were treated by direct ductal ligation during LC and 1 type A bile duct injury and 1 type C bile duct injury were managed by non-surgical treatment. Type D and type E injuries were managed by Roux-en-Y hepaticojejunostomy. CONCLUSION: Bile duct injuries are a rare but serious complications that occur during laparoscopic cholecystectomy. Most minor bile duct injuries are well treatable with non-surgical management, whereas major bile duct injuries require surgical management. The combination of non-surgical management and surgical treatment results in successful outcomes in bile duct injuries.
