Purpose: The research aimed to identify leading factors that affect a nurse’s compliance with safe handling in the use of antineoplastic agents. Methods: Data were collected from 114 nurses working in the university hospital. Data were analyzed through independent t-test, one-way ANOVA, Pearson’s correlation coefficient and multiple regression analysis using SPSS WIN 25.0. Results: The average level of compliance with safe handling of antineoplastic agents was 3.73±0.33 out of 5 points. Workplace safety climate (β=.40, p<.001) and knowledge of safe handling (β=.18, p=.030) had significant influences on nurses’ compliance with safe handling of antineoplastic agents. The explained variance for compliance was 28.3%. Conclusion To enhance the implementation of safety management for antineoplastic agents, each institution should strive to support human and material resources and to enhance specialization in the workplace safety climate through system improvement. Based on the results of this study, we suggest research for the development of an antineoplastic agents safety management training program.

BACKGROUND: We purposed to systemically review studies investigating the prophylactic effect of both pharmacological and non-pharmacological modalities against rocuronium induced withdrawal movement (RIWM) in the Korean population. METHODS: Literature search was performed using MEDLINE, EMBASE, CENTRAL, Koreamed, KMBASE, KISS and RISS up to March 2014. Randomized controlled trials (RCTs) comparing pharmacological and non-pharmacological interventions with placebo aimed for the Korean population were included. Outcome measures were the incidence and severity of RIWM. We conducted subgroup analyses according to each intervention method. RESULTS: Data were analyzed from 41 RCTs totaling 4,742 subjects. The overall incidence of RIWM was about 80% (range 56-100%). Incidence and severity of RIWM were significantly reduced with lidocaine (risk ratio [RR] 0.60, 95% CI 0.49-0.74; standardized mean difference [SMD] -0.74, 95% CI -1.05 to -0.44), opioids (RR 0.28, 95% CI 0.18-0.44; SMD -1.71, 95% CI -2.09 to -1.34) and hypnotics (RR 0.36, 95% CI 0.25-0.52; SMD -2.20, 95% CI -2.62 to -1.79). Regardless of tourniquet use, lidocaine showed a prophylactic effect against incidence and severity of RIWM: tourniquet (RR 0.36, 95% CI 0.21-0.62; SMD -1.51, 95% CI -2.15 to -0.86); non-tourniquet (RR 0.58, 95% CI 0.47-0.71; SMD -0.74, 95% CI -1.05 to -0.44). Dilution and slow injection of rocuronium decreased incidence and severity of RIWM: dilution (RR 0.47, 95% CI 0.39-0.56; SMD -1.64, 95% CI -2.47 to -0.81); slow injection (RR 0.34, 95% CI 0.17-0.70; SMD -2.13, 95% CI -2.74 to -1.51). CONCLUSIONS: The greater part of pharmacological and non-pharmacological interventions showed prophylactic effect against the incidence and severity of RIWM in the Korean population.

BACKGROUND: Factors associated with the prognosis of patients with small cell lung cancer (SCLC) is relatively unknown, than of those with non-small cell lung cancer. This study was undertaken to identify the prognostic factors of SCLC. METHODS: The medical records of 333 patients diagnosed with SCLC at tertiary hospital from January 1, 2008, to December 31, 2012 were retrospectively reviewed. Patients were categorized by age (≤65 years vs. >65 years) and by extent of disease (limited disease [LD] vs extensive disease [ED]). Overall survival and progression free survival rates were determined. Factors associated with prognosis were calculated using Cox's proportional hazard regression model. RESULTS: Most baseline characteristics were similar in the LD and ED groups. Eastern Cooperative Oncology Group (ECOG) performance status (PS), first chemotherapy regimen, and prophylactic cranial irradiation (PCI) differed significantly in patients with LD and ED. Mean ECOG PS was significantly lower (p<0.001), first-line chemotherapy with etoposide-cisplatin was more frequent than with etoposide-carboplatin (p<0.001), and PCI was performed more frequently (p=0.019) in LD-SCLC than in ED-SCLC. Prognosis in the LD group was better in younger (≤65 years) than in older (>65 years) patients, but prognosis in the ED group was unrelated to age. CONCLUSION: This study showed that overall survival (OS) was significantly improved in younger than in older patients with LD-SCLC. Univariate and multivariate analyses showed that age, PCI and the sum of cycles were significant predictors of OS in patients with LD-SCLC. However, prognosis in the ED group was unrelated to age.

PURPOSE: Competency in physical assessment is an important component of nursing practice. However, some physical assessment skills are not being utilized within the current teacher-centered, content-heavy curriculum. This study was conducted to identify the effects of student-centered, self-directed learning in the physical assessment class. METHODS: An experimental study with a post-test only control group design was used to compare an intervention group that was provided self-directed learning classes and a control group that was provided traditional lecture and practice classes. Competency in physical assessment, academic self-confidence, and learning satisfaction were evaluated. Collected data were analyzed using χ²-test (Fisher's exact test) and independent t-test. RESULTS: Competency in physical assessment was significantly higher in the experimental group. However, academic self-confidence and learning satisfaction were not significantly different between the groups. CONCLUSION: The findings in this study indicate that self-directed learning can improve nursing students competency in physical assessment and that self-directed learning is a good education method to improve nursing students' competency in physical assessment during clinical practice and perform quality patient care by making active use of physical assessment skills.

Aging is one of the risk factors for the development of cardiovascular diseases. During the progression of cellular senescence, cells enter a state of irreversible growth arrest and display resistance to apoptosis. As a flavonoid, quercetin induces apoptosis in various cells. Accordingly, we investigated the relationship between quercetin-induced apoptosis and the inhibition of cellular senescence, and determined the mechanism of oxidative stress-induced vascular smooth muscle cell (VSMC) senescence. In cultured VSMCs, hydrogen peroxide (H₂O₂) dose-dependently induced senescence, which was associated with increased numbers of senescence-associated β-galactosidase-positive cells, decreased expression of SMP30, and activation of p53-p21 and p16 pathways. Along with senescence, expression of the anti-apoptotic protein Bcl-2 was observed to increase and the levels of proteins related to the apoptosis pathway were observed to decrease. Quercetin induced apoptosis through the activation of AMP-activated protein kinase. This action led to the alleviation of oxidative stress-induced VSMC senescence. Furthermore, the inhibition of AMPK activation with compound C and siRNA inhibited apoptosis and aggravated VSMC senescence by reversing p53-p21 and p16 pathways. These results suggest that senescent VSMCs are resistant to apoptosis and quercetin-induced apoptosis attenuated the oxidative stress-induced senescence through activation of AMPK. Therefore, induction of apoptosis by polyphenols such as quercetin may be worthy of attention for its anti-aging effects.

OBJECTIVE: Analyses of the status of 119 emergency situation control center (119 ESCC) usage are lacking. Therefore, this study investigated the status of the 119 ESCC usage, including dispatcher-assisted cardiopulmonary resuscitation (DA-CPR) instructions. METHODS: The emergency activity daily reports and emergency instruction sheets of 119 ESCC from January to December 2016 were reviewed. For more accurate status analysis, the computerized data of the 1339 Emergency Medical Information Center from January to December 2011 were also reviewed. RESULTS: In 2016, the total usage of the 119 ESCC was 1,393,876 calls, which was 27.8% lower than the 1,930,977 calls in 2011. Of the 1,393,876 eligible calls, the most common call was hospital guidance (n=743,799, 53.4%), followed by first aid (n=397,620, 28.5%), disease consultation (n=150,128, 10.8%), medical oversight (n=81,174, 5.8%), and interhospital transfer (n=5,123, 0.4%). Regarding the user number per 10,000 persons, Daejeon was the greatest at 57.2, whereas Changwon was the lowest at 11.5. A total number of DA-CPR was 19,439. The time from the call to chest compression were 173±88.6 seconds in the subjects having previous cardiopulmonary resuscitation training and 184.0±88.2 in the subjects having no such training (P < 0.001). CONCLUSION: The ratio of first aid instructions, including DA-CPR, among total usage of the 119 ESCC increased but the overall usage of the 119 ESCC decreased. Therefore, further efforts will be needed to improve the quality and professionality of the information provided through the operation of 119 ESCC.

Spinal and bulbar muscular atrophy (Kennedy disease) is an X-linked, adult-onset motor neuron disease characterized by slow, progressive weakness of the bulbar and extremity muscles with CAG triplet repeat expansion in the androgen receptor gene. Hirayama disease (HD) is characterized by the juvenile onset of asymmetric weakness and amyotrophy of the hand and is most common in males in Asia. We report a patient with atypical Kennedy disease presenting with asymmetric hand weakness and atrophy typical of HD.

PURPOSE: The study investigated the educational needs and perceptions of school nurses regarding emergency situations in the school and compared differences in the educational needs and perceptions about emergency situations according to the general characteristics of school nurses. METHODS: Using a written survey of randomly selected sample, we questioned 100 school nurses over a 3-month period from January 2011 to March 2011. The survey involved 11 medical conditions and 16 injury-related conditions. It contained questions about the need for education and perceptions of emergency situations. We also determined school nurses' general characteristics including sex, age, grades of school where they worked, years of teaching career, years of clinical experience, number of classes, marital status, number of children, gender of their children, age of their children, the existence of older families. RESULTS: Two hundred two (84%) school nurses responded. For most conditions, there were significant differences between the scores of educational needs regarding, and perceptions about, emergency situations, except for three conditions (fracture of extremity, cerebral contusion, and tooth trauma). According to the general characteristics of school nurses, only the grade of school where they worked influenced the educational needs for cerebral contusion and orbital contusion. CONCLUSION: The emergency conditions that need first aid education in Korean school nurses are different from the conditions identified in other foreign countries. Primary education and promotion of first aid is considered necessary. The perceptions about emergency situations and the educational need regarding emergency situations show consistency. Only the grade of school where nurses worked affected the educational needs of school nurses. Further studies about the frequency of emergency situations in each school grade are required.

BACKGROUND/OBJECTIVES: Although globally the numbers of children diagnosed with failure to thrive (FTT) have decreased, FTT is still a serious pediatric problem. We aimed to investigate the effects of zinc supplementation for 6 months on growth parameters of infants and children with FTT. SUBJECTS/METHODS: In this retrospective study, of the 114 participants aged between 4 months and 6 years, 89 were included in the zinc supplementation group and were provided with nutrition counseling plus an oral zinc supplement for 6 months. The caregivers of the 25 participants in the control group received nutrition counseling alone. Medical data of these children, including sex, age, height, weight, serum zinc level, and serum insulin-like growth factor 1 (IGF1) level were analyzed. RESULTS: Zinc supplementation for 6 months increased weight-for-age Z-score and serum zinc levels (5.5%) in the zinc supplementation group of underweight category children. As for stunting category, height-for-age Z-score of the participants in the zinc supplementation group increased when compared with the baseline, and serum zinc levels increased in the normal or mild stunting group. Serum IGF1 levels did not change significantly in any group. Thus, zinc supplementation was more effective in children in the underweight category than those in the stunted category; this effect differed according to the degree of the FTT. CONCLUSION: These findings suggest that zinc supplementation may have beneficial effects for growth of infants and children with FTT, and zinc supplementation would be required according to degree of FTT.

PURPOSE: Extrathyroidal extension (ETE) is one of the risk factors to be considered when deciding on operation extent and radioiodine ablation in differentiated thyroid carcinoma. Ultrasonography (USG) is the most widely used imaging modality in preoperative evaluation of thyroid carcinoma; however, few studies regarding accuracy of USG in preoperative evaluation of ETE have been reported. In this study, we investigated the accuracy of preoperative USG in detection of ETE and evaluated other risk factors associated with permanent ETE. METHODS: We reviewed the medical records of 349 consecutive patients who underwent curative thyroidectomy for differentiated thyroid carcinoma. Preoperative USG findings according to percent of contact and disruption of thyroid capsule were evaluated and compared with the permanent pathology. Clinicopathologic characteristics were investigated for assessment of the risk factors associated with ETE. RESULTS: ETE was identified in permanent pathology of 68 (19.5%) patients. When we defined the ETE on preoperative USG as more than 25% contact with the adjacent capsule, the positive predictive value (PPV) and negative predictive value (NPV) were 43.03% and 90.73%, respectively. Size of the nodule and preoperative USG findings with the percent of contact with adjacent capsule and capsule disruption showed an association with ETE on permanent pathology. However, in multivariate analysis, only size of the nodule and capsule disruption on USG were identified as risk factors for prediction of ETE on permanent pathology. CONCLUSION: Capsule disruption on preoperative USG can provide useful predictive information about permanent ETE. Another risk factor associated with ETE was size of nodule in differentiated thyroid carcinoma.
