The effects of food safety education on adolescents' hand hygiene behavior: an analysis of stages of change

The hand hygiene behavior of 400 middle school students (grades 1-3) in Seoul and Gyeonggi-Do was studied to determine how stages of change were affected by food safety education, focusing on hand hygiene and general food safety. Subjects were 51.3% male and 44.3% of study subjects were first graders of middle school. Approximately 40% of subjects were at the stage of action, 42.7% were at the stage of contemplation, and 16.4% were at pre-contemplation. The most important factor that influenced proper hand washing was self efficacy (P < 0.001). Proper hand washing was also correlated significantly with positive belief (P < 0.01) and stages of change (P < 0.01). After food safety education by high-school mentors, middle-school students who were in the stages of pre-contemplation (11.1%) and contemplation (88.9%) showed significant progression toward the action stage (P < 0.001). Proper hand washing (P < 0.01) and food safety knowledge (P < 0.05) were also significantly increased after educational intervention.

Postoperative obstructing laryngeal edema in patients with diffuse idiopathic skeletal hyperostosis of cervical spine: A report of two cases / 대한마취과학회지

Two cases were reported in which severe postoperative laryngeal edema were developed after the operation of diffuse idiopathic skeletal hyperostosis (DISH) of cervical spine. In the first case, sudden airway obstruction was developed in the general ward 6 hour after uneventful decompression surgery for osteophyte. In the second patient, an elective preoperative tracheostomy was performed before surgery but the tube could not be removed for 2 months because of laryngeal edema and decreased vocal cord mobility. It should be emphasized that this airway problem can develop during the postoperative as well as the preoperative period, especially in the case of anterior cervical spine surgery.

Eating habits, obesity related behaviors, and effects of Danhak exercise in elderly Koreans

The aims of this study were to evaluate obesity-related dietary behaviors and to determine long-term exercise effects on obesity and blood lipid profiles in elderly Korean subjects. A total of 120 subjects, aged 60-75 yr, were recruited, and obesity-related dietary behaviors were determined. An exercise intervention was conducted with 35 qualified elderly females for 6 months, and body composition and blood lipids were measured 6 times at 4 week intervals. At baseline, mean BMI (kg/m2) was 24.8 for males and 23.1 for females. The females had better eating habits than the males and were more concerned with reading nutrition labels on food products (P < 0.001); they also preferred convenience foods less than the male subjects (P < 0.05). Obese individuals were more likely than overweight or normal weight individuals to misperceive their weight (P < 0.001). Those with a high BMI responded feeling more depressed (P < 0.01), lacking self-confidence (P < 0.01), and feeling isolated (P < 0.01), as well as having more difficulty doing outdoor activities (P < 0.01). After exercise, body fat (%) and WHR were significantly reduced (P < 0.05), while body weight and BMI were also decreased without statistical significance. Total cholesterol and blood HDL were significantly improved (207.1 mg/dl vs. 182.6 mg/dl, HDL: 45.6 mg/dl vs. 50.6 mg/dl, P < 0.05). Other benefits obtained from exercise were improvements in self-confidence (26.4%), movement (22.6%), stress-relief (18.9%), and depression (13.2%). In conclusion, elderly females had better eating habits and were more concerned with nutrition information and healthy diets compared to elderly males. However, misperceptions of weight and obesity-related stress tended to be very high in females who were overweight and obese, which can be a barrier to maintain normal weight. Long-term Danhak practice, a traditional Korean exercise, was effective at reducing body fat (%) and abdominal obesity, and improved lipid profiles, self-confidence, and stress.

Psycho-Social Well-being, Health Perception and Behavior among Clinical Nurses / 간호행정학회지

PURPOSE: The purpose of this study was to investigate the relationships among psycho-social well-being, and health perception and behavior in clinical nurses. METHODS: The data were collected from 362 nurses employed at five general hospitals. A self-reported questionnaire was used to assess demographics and job characteristics, health perception and behavior, depression, and psycho-social stress. The data were analysed using Cronbach's alpha, descriptive statistics, t-test, and ANOVA. RESULTS: While nurses perceived themselves to be in good health, represented by a high mean for health perceptions, actual health behavior was poor as the mean for health behavior was low. Forty two percents of the subjects were categorized as having major depression and high-stress levels. There were statistically significant differences in psycho-social well-being according to age, marital status, years of employment, and monthly salary. Also, there were significant differences in psycho-social well-being according to health perception, regular meals and exercise, sufficient sleep, job related injury and accident, and absences for ill. CONCLUSION: In order to prevent depression and improve psycho-social well-being among clinical nurses, organizational support and health management needs to be focused on high-risk nurses. Furthermore, it is essential to consider the health perception and behavior of clinical nurses.

Food safety knowledge and practice by the stages of change model in school children

In this study, 342 grade 4-6 elementary school students in Gyeonggi-do were recruited to determine their readiness to change food safety behavior and to compare their food safety knowledge and practices by the stages of change. The subjects were divided into three stages of change; the percentage of stage 1 (precontemplation) was 10.1%, the percentage of stage 2 (contemplation and preparation) was 62.4%, and that of stage 3 (action and maintenance) was 27.5%. Food safety knowledge scores in stage 3 (4.55) or stage 2 (4.50) children were significantly higher than those in stage 1 children (4.17) (P < 0.05). The two food safety behavior items "hand washing practice" and "avoidance of harmful food" were significantly different among the three groups (P < 0.05). Stages of change were significantly and positively correlated with food safety knowledge and practice. Age was significantly and negatively correlated with the total food safety behavior score (r = -0.142, P < 0.05). The most influential factor on the stage of change was a mother's instruction about food safety (P < 0.01).

The Effects of Continuous Nicardipine Infusion on Blood Pressure and Heart Rate during Endotracheal Intubation / 대한마취과학회지

BACKGROUND: Laryngoscopy and tracheal intubation often induced an undesirable increase in blood pressure and heart rate. We evaluated the preventing effect of nicardipine infusion on the increase of the blood pressure (BP) and heart rate (HR) following a direct laryngoscopy and tracheal intubation. METHODS: Sixty, ASA physical status 1-2, adult patients were selected with informed consent, and randomly allocated into two groups; control group (n = 30) and nicardipine group (n = 30). In the control group, 1.8 ml/kg/h of normal saline was infused, and in the nicardipine group, 5microgram/kg/min of nicardipine was infused continuously from 2 minutes before intubation to 3 minutes after intubation. BP and HR were measured by non-invasive method after arrival at the operating room, before tracheal intubation, shortly after tracheal intubation, and 1, 3, 5, and 10 minutes following intubation. Data were analyzed by repeated measure of ANOVA and t-test. RESULTS: Systolic and diastolic BP were significantly lower in the nicardipine group than in the control group (P < 0.05). HR showed significantly higher value in the nicardipine group (P < 0.05). CONCLUSIONS: The continuous infusion of nicardipine (5microgram/kg/min) was effectively attenuating an increase of BP during tracheal intubation. But the increase in HR is not blunted by nicardipine infusion and there is a significant increase in HR. Although rate-pressure product (RPP) does not increase, the use of nicardipine for blunting hemodynamic responses should be considered carefully in patients with ischemic heart disease.

Concept Analysis of Preparatory Grief in Terminal Cancer Patients / 간호학회지

PURPOSE: The purpose of this study was to conceptualize and clarify a concept of "preparatory grief" in terminal cancer patients. METHOD: A hybrid model of concept development was applied to develop a concept of preparatory grief, which included a field study carried out in Busan, Korea. Participants of this study were 8 cancer patients. RESULTS: On the basis of our literature, research and clinical experience, the concept of preparatory grief emerged as a complex phenomenon playing an important role in five areas; physical, emotional, interpersonal, religious, and transcendental dimensions. Two new attributes were defined through a field phase; trust of the post-mortal world and a serene state of mind. Indicators reflected attitudes of sadness, worry, regret, capability to adapt and hope. The results of preparatory grief were loss of energy and interest, emotional chaos, contemplation, taciturnity and restoration. CONCLUSIONS: Differentiating among preparatory grief and other symptoms in cancer patients is essential because of therapeutic implications. Understanding preparatory grief is necessary in order to manage cancer patients for promoting quality of life so that its application may have a positive impact on the patient's life.

The Effects of Deep Breathing Methods on Pulmonary Ventilatory Function of Pneumothorax Patients undergoing a Thoracotomy / 간호학회지

PURPOSE: This study was to examine the effects of deep breathing exercises with Incentive Spirometer on the pulmonary ventilatory function of pnemothorax patients undergoing a thoracotomy. METHOD: This experiment used anonequivalent control group non-synchronized design which compared pre-experimental measures with post-experimental ones. The subjects of this study were 34 inpatients who were scheduled for a thoracotomy and classified into the experimental group (17 patients) or control group (17 patients) by using an Incentive Spirometer or not. The collected data was analyzed by a SPSS Win / PC (percentage, mean, standard deviation, chi-square test, t-test, repeated measured two-way ANOVA). RESULT: The Pulmonary Ventilatory Function of the experimental and control group were significantly increased on the first day, third day, and fifth day after the thoracotomy, but the group interaction period was not significant. CONCLUSION: This study showed that the deep breathing exercises with an Incentive Spirometer and deep breathing exercise without an Incentive Spirometer were both effective for recovering the pulmonary ventilatory function after a thoracotomy.

Hemodynamic and Preemptive Analgesic Effect of Preoperative Epidural Analgesia during Laparoscopic Hysterectomy / 대한마취과학회지

BACKGROUND: A laparoscopic hysterectomy is gaining popularity on account of its many benefits. The trendelenburg position and pneumoperitoneum necessary for a laparoscopy causes intraoperative hemodynamic fluctuations. The aim of this study was to evaluate the intraoperative hemodynamic and postoperative analgesic effects of preemptive epidural analgesia in a laparoscopic hysterectomy. METHODS: Fifty ASA 1 and 2 patients were randomized to two groups. Nothing was applied to the control group before inducing general anesthesia. In the epidural group, an epidural catheter was inserted through the L2-3 space and 1% lidocaine 10 ml was injected. The blood pressures, heart rates, cardiac outputs, stroke volumes and cardiac indexes were measured using NICO(TM) (Non-Invasive Cardiac Output using partial carbon dioxide rebreathing technique, fast mode, Novametrix Medical Systems Inc, USA) at time before induction (T1), post-intubation (T2), post-insufflation and in the trendelenburg position (T3), post-intubation 10 (T4), 20 (T5), 30 (T6) and 60 minutes (T7), post-exsufflation (T8) and post-neutral position (T9). The pain scores were assessed by the patients using a 100 mm visual analogue scale at 1, 3, 6, 12 and 24 hours postoperatively. RESULTS: There were important differences in the blood pressures, cardiac outputs, stroke volumes and cardiac indexes between the two groups. No significant changes in the heart rate were observed during surgery in either groups. The postoperative pain scores were significantly lower in the epidural group compared with the control group. CONCLUSIONS: Preemptive epidural analgesia produces a more stable hemodynamic state during a laparoscopic hysterectomy and reduces the level of postoperative pain.

Effectiveness of Triple Therapy and Quadruple Therapy for Helicobacter pylori Eradication / 대한소화기학회지

BACKGROUND/AIMS: Quadruple therapy can be considered as a first-line therapy in areas where the resistance rate to clarithromycin is high. Comparison study of triple therapy and quadruple therapy for Helicobacter pylori (H. pylori) eradication is still lacking in Korea despite the increasing prevalence of antibiotic resistance. This study was conducted to compare the efficacy of triple and quadruple therapy as a first-line treatment in H. pylori infected patients with peptic ulcer. METHODS: Consecutive 149 cases of peptic ulcer disease associated with H. pylori infection were randomized either to proton pump inhibitor (PPI, bid), amoxicillin (1,000 mg, bid), and clarithromycin (500 mg, bid) (PAC group) or to PPI (bid), bismuth subcitrate (300 mg, qid), metronidazole (500 mg, tid), and tetracycline (500 mg, qid) (PBMT group) eradication treatments for 7 days. Outcome of eradication therapy was assessed by 13C-urea breath test performed 4-6 weeks after eradication. RESULTS: Eradication rates in PAC and PBMT group were 78.7% (59/75) and 71.6% (53/74) by intention to treat analysis, respectively (p=0.424). By per protocol analysis, eradication rates of PAC and PBMT group were 85.5% (59/69) and 85.5% (53/62), respectively (p=1.012). Adverse reactions occurred in 5 (6.6%) and 7 (9.5%) patients in PAC and PBMT group, respectively (p=0.346). CONCLUSIONS: One week-quadruple therapy as a first-line treatment for H. pylori infection does not offer any advantage over PPI-based triple therapy in Korean patients.
