PURPOSE: The purpose of study was to compare perceived nursing needs between patients having spinal surgery and the nurses caring for them. METHOD: The participants were from three general hospitals, 71 patients who were having spinal surgery and 63 nurses. Data were collected from September 18 to November 17, 2006. Frequencies, mean, and t-test with the SPSS PC 14.0 program were used to analyze the collected data. RESULTS: The score for perceived nursing needs during pre-op care was significantly different between the patients and nurses (t= -2.515, p= .013). The perceived nursing needs did not show significant differences in scores of perceived nursing needs at post-op or discharge. CONCLUSION: The results provide primary data to improve the quality of nursing care, plan, and implement appropriate nursing care for patients undergoing spinal surgery.

PURPOSE: We tried to evaluate the long term efficacy and positive predictive factors of interferon-alpha treatment in children with chronic hepatitis B. METHODS: The study population included 113 children who received interferon therapy between May 1982 and July 2002 (20 years) for chronic hepatitis B in Department of Pediatrics, Yonsei University College of Medicine. Male to female ratio was 2.3:1 and the mean age at diagnosis was 11.1+/-4.1 years old. Response to treatment was defined as normalization of alanine aminotransferase (ALT), disappearance of HBeAg and HBV-DNA Eighty two children responded while 32 did not. Interferon-alpha was given intramuscularly for 6 months at a dosage of 3x106 unit, 3 times weekly. In relapsed cases, lamivudine or interferon retreatment was done. RESULTS: Seroconversion rate was 77.0% in terms of HBeAg, 74.3% in terms of HBV-DNA, and 80.5% in terms of ALT normalization after treatment. Seroconversion rate of both HBeAg and HBV-DNA was 72.6%. Analyzed by life table method, the effect of the treatment had been maintained over 10 years after cessation of therapy. Pre-treatment ALT level was the only significant positive predictive factor of response. Eleven cases (13.4%) relapsed, and 2 out of 3 showed response when treated with lamivudine and 1 out of 3 with interferon retreatment. CONCLUSION: Interferon-alpha showed significant efficacy in the treatment of chronic hepatitis B in our study. Further studies about the effect of interferon therapy on complications of hepatitis such as hepatocarcinoma, cirrhosis are warranted.

PURPOSE: We analyzed the risk factors affecting readmission of children with pneumonia. METHODS: We retrospectively analyzed the medical records of pediatric patients admitted to the Department of Pediatrics at the Jeonju Presbyterian Medical Center from January 2007 to August 2016. We classified patients who were readmitted with pneumonia within 30 days of discharge as the readmission group and patients who were admitted with pneumonia for the first time as the first admission group. RESULTS: Among 158 patients, the study (readmission) group included 82 patients and the control (first admission) group included 76 patients. Age, the percentage of segmented neutrophils and lymphocytes, the number of admissions in the last 12 months, the associated diseases (respiratory diseases such as asthma), and the affection of the right upper lung were analyzed as risk factors for readmission. However, based on a regression analysis, only age and associated diseases were found to be significant risk factors. The rate of readmission increased with younger age. When there were associated diseases, the rate of readmission also increased. CONCLUSIONS: Young age and associated diseases were significant risk factors for readmission for patients with pediatric pneumonia. When pediatric patients are admitted with pneumonia, if they are young and/or have associated diseases, a comprehensive approach is needed to reduce the rate of readmission with careful consideration of precise examination, treatment, timing of discharge, and follow-up.

In this study, eight soil samples were collected from organic and conventional farms in a central area of South Korea. Spore communities of arbuscular mycorrhizal fungi (AMF) and glomalin, a glycoprotein produced by AMF, were analyzed. Spores of Glomus clarum, G. etunicatum, G. mosseae, G. sp., Acaulospora longula, A. spinosa, Gigaspora margarita, and Paraglomus occultum were identified at the study sites, based on morphological and molecular characteristics. While Acaulospora longula was the most dominant species in soils at organic farms, Paraglomus occultum was the most dominant species in soils at conventional farms. Species diversity and species number in AMF communities found in soils from organic farms were significantly higher than in soils from conventional farms. Glomalin was also extracted from soil samples collected at organic and conventional farms and was analyzed using both Bradford and enzyme-linked immunosorbent assays. The glomalin content in soils from organic farms was significantly higher than in soils from conventional farms. These results indicate that agricultural practices significantly affect AMF abundance and community structure.

BACKGROUND AND OBJECTIVES: Pulmonary thromboembolism (PTE) after surgery is one of the rare but fatal complications causing sudden respiratory failure. This study was performed to evaluate PTE after head and neck surgery and to report our recent experience with review of the literature. SUBJECTS AND METHOD: We retrospectively analyzed 1096 patients who underwent head and neck surgery from January 2011 to June 2013 in a tertiary hospital. We evaluated the incidence and characteristics of PTE and risk factors of PTE such as smoking, body mass index, comorbidities, coronary artery disease, coagulation disorder and Caprini risk assessment model. RESULTS: PTE occurred in five of 1096 patients (0.46%; two were male and three were female, with a mean age of 56.2 year). All patients with PTE were categorized into high risk group of PTE by Caprini model. The mean Caprini risk score were 6.6 and 4.6 in the PTE patients and non-PTE patients, respectively. The significant risk factors were long operative time, cancer patients and high Caprini score in this study. One PTE patient underwent cardiopulmonary resuscitation due to respiratory arrest, afterwards received thromboembolectomy by thoracotomy. Four patients received anticoagulation therapy only. CONCLUSION: Risk stratification for PTE is necessary in patients who receive long operation for head and neck cancer or have high Caprini score.

In the present study, toxicity of silver nanoparticles (AgNPs) was investigated in the nematode, Caenohabditis elegans focusing on the upstream signaling pathway responsible for regulating oxidative stress, such as mitogen-activated protein kinase (MAPK) cascades. Formation of reactive oxygen species (ROS) was observed in AgNPs exposed C. elegans, suggesting oxidative stress as an important mechanism in the toxicity of AgNPs towards C. elegans. Expression of genes in MAPK signaling pathways increased by AgNPs exposure in less than 2-fold compared to the control in wildtype C. elegans, however, those were increased dramatically in sod-3 (gk235) mutant after 48 h exposure of AgNPs (i.e. 4-fold for jnk-1 and mpk-2; 6-fold for nsy-1, sek-1, and pmk-1, and 10-fold for jkk-1). These results on the expression of oxidative stress response genes suggest that sod-3 gene expression appears to be dependent on p38 MAPK activation. The high expressions of the pmk-1 gene 48 h exposure to AgNPs in the sod-3 (gk235) mutant can also be interpreted as compensatory mechanisms in the absence of important stress response genes. Overall results suggest that MAPK-based integrated stress signaling network seems to be involved in defense to AgNPs exposure in C.elegans.
