  • This study was aimed to analyze the variables measuring stress and immune responses, to identify the relationship between stress and immune responses, and to find out the effect of nursing interventions associated with stress and immune responses by reviewing thirty-four published articles since 1970 in Korea. The articles were selected in the field of nursing, stress management, and masters or doctoral dissertations and limited to human subject. Among these, the thirty-one articles were published since 1996 and mainly distributed in nursing (44.1%) and medicine(44.1%). The prevailing research design was nonequivalent control pre-post experimental design(41.1%). The research subjects were 55.9% for patients and 44.1% for healthy general persons including 20.6% of university students. To evaluate stress, both physiologic and psychosocial measures were adapted together in 35.3% of the articles. The most frequent two variables measuring stress and immune response were cortisol level(15.9%) and number or activity of natural killer cell(25.9%). The relation between stress and immune responses was positive in 4 articles, negative in 9 cases, and none in 12 cases. Decreased stress and enhanced immune function have been found when massage, abdominal breathing, exercise, relaxation, and touch were provided as nursing interventions. The articles to investigate the relationship between stress and immune function were limited and the tested variables were diverse. Also there was no consistent evidence to correlate the stress and immune function at present. Further studies are needed to construct a valid research design and to investigate the relationship between stress and immune responses. Nursing interventions to decrease stress should be developed to result in the increased immune function and the effect of these interventions would be verified.

  • This study was conducted by analyzing all 33 articles based on the LISREL, published from January 1991 to March 1999 in Korea. The analyses consisted of the publication date of articles, principal dependent variables, subjects of the research, adequacy of sampling, adequacy of research purposes and results, accordance between theoretical model and hypothetical model, fit measures, theoretical base of model modification, and adequacy of conclusion. The results were as follows : . The thesis of 33 articles in total were outnumbered as 25 (75.8%) to 8 (24.2%) research articles. As for a sex classification of the subjects, 45.5% of the research were conducted around a female group of subjects, while 54.5% were done for both sex, The range of the sample size was 105 to 803, and the average was 259 subjects. . A single theoretical variable was measured for each measurement variable, any difference between variables was hardly found in 8 articles (24.2%), and 19 articles (57.6%) did not consider any measurement error. To analyze if the representative has been articles (21.2%) were seen with a sign of a representative. Questionnaires were used in a majority (31 articles) of the data collecting process. Only 2 articles (6.1%) were measured with a physiologic index simultaneously. . 14 articles (42.2%) were centered on theory development, 10 articles on theory synthesis, and 9 articles on theory test. The research purposes and results were consistent in 25 articles (75.5%) and 8 articles (24.2%) were inconsistent. The quality of life and health promotion behavior were the concepts most frequently studied as a dependent variable, and 7 articles centered on them. In applied theories a health promotion model was used on 4 articles (12.1%), while role theory and stress-coping models were in 3 articles respectively. . The articles were analyzed to see if the hypothetical model was elaborated and tested by the theoretical model. Twenty-five articles proved to be rationale for the inconsistencies. Also, 56.5% proposed hypotheses were supported among the subject articles, and 30 articles (90.0%) suggested a revised model. Path coefficient (17 articles) and theoretical adequacy (17 articles) were the standards mostly used. In conclusion, the principal factors were obtained from the research are to be considered as the principes of LISREL application. First, a model has to be established on a theoretical base rather than empirical results dependent on the data. The results are also required to be globally interpreted. Secondly, at least 200 samples are necessary to satisfy the need. Third, more than 3 measurement variables are to be adjusted to a single theoretical variable; the measurement errors must be suggested as well. Finally, normal distribution characteristics of the data and the estimation method need to be reported. Based on the research result, the follows are suggested; . Systematic criteria on the LISREL application and procedure need to be developed . Agreement form is required to report the results of research using the LISREL

  • A great deal of attention has been paid to the quality of life in citizens due to the increased number of long term life expectancy. reported as effective in the health promotion of the senior citizens. In this study, the principal investigator developed an exercise program for the senior citizens, which could be educated and managed by nursing staff. This kind approach may support the need of exercise program on regular base via the social organization, which may mean the intentional change of life style. The exercise program consisted of exercise, health education, and a direct the population of the senior A regularexercise has been nursing care. A quasi -experimental study was conducted to investigate the effects of excercise program on health of the elderly in senior citizen's center. Independent variable was a 9 weeks exercise program. Dependent variables were: 1) physical health [e.g. physical fitness(cardiopulmonary endurance, back muscle strength, grip strength, muscular tolerance, flexibility and body fat proportion), physiologic parameters(blood pressure, pulse, respiration. and blood glucose), and perceived physical health status; 2) mental health measured by depression score; and 3) cognitive perception of exercise measured by usefulness and self-efficacy. A total of 37 subjects was randomly assigned into either the control group (without the exercise program: n=18) or the intervention group(with the exercise program: n=19). The results of the study analyzed using a SAS, were as follows: 1) In physical fitness of physical health, there was a significant improvement in cardiopulmonary tolerance. back muscle strength. muscular tolerance and flexibility in the intervention group, compared to the control group, while no difference in grip strength and body fat proportion. The exercise program resulted in decreases in blood pressure, pulse, respiration and blood glucose within normal range and improvement of perceived physical health status in the intervention group. 2) There was a slight increase of mental health(depression score) in the intervention group compared to the control group. but without statistical significance. 3) There was a significant improvement in cognitive perception of exercise(e.g. usefulness and self -efficacy) in the intervention group, compared to the control group. It was concluded that the exercise program employed in this study was appropriate for women senior citizens and had a positive effect on health in general.

  • Purpose: The most common cuase of transfusion for trauma victims in an emergency department is hypovolemic shock due to injury. After an injury to an internal organ of the chest or the abdomen, transfusion is needed to supply blood products and to compensate tissue oxygen transport and bleeding. From the 1990's, there have been some reports that transfusion is one of the major factors causing multiple-organ failure. Thus, as much as possible, tranfusion has been minimized in the clinical setting. This study aims to analyze the prognostic factors for mortality among trauma victims transfused with blood products in an emergency department. Methods: We conducted this study for the year of 2010 retrospectively. The study group included adult trauma victims tranfused with blood products in our ED. The exclusion criteria were discharge against medical advice, and missing follow-up due to transfer to another facility. During the study period, 34 adult trauma victims were enrolled. We compared the clinical variables between survivors and non-survivors. Results: the mean age of the 34 victims was 58.06 years, and males account for 58.5% of the study group. The most-frequently used form transportation was ambulance(119, 55.9%), and the most common injury mechanism was mobile vehicle accidents(67.6%). The mean revised trauma score (RTS) was 5.9, and the mean injury severity score (ISS) was 47.76. The mortality rate in the ED was 58.5%, Comparison of survivors with non-survivors showed statistical differences in injury mechanism, initial SBP, DBP, RTS, ISS, and some laboratory data such as AST, ALT, pH, PO2, HCO3, glucose (p<0.05). Regression analyses showed that mortality among adult trauma victims transfused in the ED correlated with RTS. Conclusion: When an adult trauma victim is transported to the ED and needs a tranfusion, the emergency physician carefully assess the victim by using physiologic data.

  • Electroencephalography (EEG) is frequently used to assist the diagnosis of brain death. However, to date there have been no guidelines in terms of EEG criteria for determining brain death in Korea, despite EEG being mandatory. The purpose of this review is to provide an update on the evidence and controversies with regarding to the utilization of EEG for determining brain death and to serve as a cornerstone for the development of future guidelines. To determine brain death, electrocerebral inactivity (ECI) should be demonstrated on EEG at a sensitivity of $2{\mu}V/mm$ using double-distance electrodes spaced 10 centimeters or more apart from each other for at least 30 minutes, with intense somatosensory or audiovisual stimuli. ECI should be also verified by checking the integrity of the system. Additional monitoring is needed if extracerebral potentials cannot be eliminated. Interpreting EEG at high sensitivities, which is required for the diagnosis of brain death, can pose a diagnostic challenge. Furthermore, EEG is affected by physiologic variables and drugs. However, no consensus exists as to the minimal requirements for blood pressure, oxygen saturation, and body temperature during the EEG recording itself, the minimal time for observation after the brain injury or rewarming from hypothermia, and how to determine brain death when the findings of ECI is equivocal. Therefore, there is a strong need to establish detailed guidelines for performing EEG to determine brain death.

  • Purpose: This study was undertaken to explore sex differences in the risk markers of cardiovascular disease (CVD) and psychosocial factors and the relationships among these variables for the community-residing adults. Methods: A cross-sectional study was conducted with a total of 114 participants consisting of 65 men aged 42.85 years old and 49 women aged 46.86 years old. Participants were selected by a convenient sampling of at community cultural centers and churches. They completed a structured questionnaire including demographic characteristics, physiologic risk markers of CVD; lifestyle factors; and depression, social support, and stress. Results: The male participants showed significantly higher systolic and diastolic blood pressures than their counterparts. Significantly higher percent of women were currently non-smokers, and practiced moderate alcohol intake, physical activity, and low fat diet. Among women, the higher the scores of depression and stress were and the lower that of the social support was, the higher blood pressure, waist circumference and BMI were. Among men, those who were less depressed and with higher scores of social support had more physical activity. Conclusion: The findings suggest further studies to explore sex differences of CVD risk markers and psychosocial factors, and their relationships in a larger sample, and to find the mechanism underlying these differences with a prospective design.

  • Purpose: The purpose of this study was to identify the effects of an exercise program on muscle strength, Activities of Daily Living (ADL), health perception, and depression among post-stroke elders. Methods: Nonequivalent control group design with pretest and posttest was used. A total of 23 post-stroke elders who met inclusion criteria were recruited. Muscle strength in upper and lower extremities, ADL, health perception, and self-rated symptoms of depression were measured. The exercise program consisted of deep breathing, range of motion, and muscle strengthening exercises using Thera-band, 30~40 min/day, three days a week, for 12 weeks. Results: Muscle strength of right shoulder (U=11.50, p=.001), right leg (U=13.50, p=.002), and health perception (U=24.00, p=.010) in the experimental group was significantly higher compared to the control group at 12 weeks of post-intervention. Depression scores were significantly lower in the experimental group compared to the control group at 6 weeks (U=28.00, p=.021), at 12 weeks (U=22.00, p=.006) of an exercise program. Conclusion: By applying this program, post-stroke elders showed increases in muscle strength and a decrease in depression as well as improvement of health perception. Further study is needed to verify the effects of the exercise program on cardiovascular physiologic variables through long-term follow-up.

  • The cyclic alternating pattern (CAP) is a periodic EEG activity in NREM sleep, characterized by sequences of transient electrocortical events that are distinct from background EEG activities. A CAP cycle consists of two periodic EEG features, phase A and subsequent phase B whose durations are 2-60 s. At least two consecutive CAP cycles are required to define a CAP sequence. The CAP phase A is a phasic EEG event, such as delta bursts, vertex sharp transients, K-complex sequences, polyphasic bursts, K-alpha, intermittent alpha, and arousals. Phase B is repetitive periods of background EEG activity. The absence of CAP more than 60 seconds or an isolated phase A is classified as non-CAP. Phase A activities can be classified into three subtypes (A1, A2, and A3), based on the amounts of high-voltage slow waves (EEG synchrony) and low-amplitude fast rhythms (EEG desynchrony). CAP rate, the percentage of CAP durations in NREM sleep is considered to be a physiologic marker of the NREM sleep instability. In insomnia, the frequent discrepancy between self-reports and polysomnographic findings could be attributed to subtle abnormalities in the sleep tracing, which are overlooked by the conventional scoring methods. The conventional scoring scheme has superiority in analysis of macrostructure of sleep but shows limited power in finding arousals and transient EEG events that are major component of microstructure of sleep. But, it has recently been found that a significant correlation exists between CAP rate and the subjective estimates of the sleep quality in insomniacs and sleep-improving treatments often reduce the amount of CAP. Thus, the extension of conventional sleep measures with the new CAP variables, which appear to be the more sensitive to sleep disturbance, may improve our knowledge on the diagnosis and management of insomnia.

  • We evaluated folate status of child-bearing age women diagnosed with abnormal pap smear in the US post-folic acid (FA) fortification era and assessed the determinants of NTD-protective and supra-physiologic (SP) concentrations of folate. The distribution of 843 women according to NTD-protective concentrations of RBC folate, plasma folate and SP concentrations of plasma folate were tested in relation to demographic and life-style factors. Logistic regression models specified NTD-protective concentrations of RBC and plasma folate or SP concentrations of plasma folate as dependent variables and demographic and life-style factors as independent predictors of interest. More than 82% reached NTD-protective concentrations of RBC and plasma folate and ~30% reached SP concentrations of plasma folate. FA supplement use was associated with having SP concentrations of plasma folate rather than NTD-protective concentrations of folate. African American (AA) women and smokers were significantly less likely to achieve NTD-protective concentrations of RBC and plasma folate. A large majority of women reached NTD-protective concentrations of folate with the current level of FA fortification without using supplementary FA. Therefore, the remaining disparities in AA women and in smokers should be addressed by targeted individual improvements in folate intake.
