Background: Psychological factors are increasingly recognized for their influence on the course of asthma, on a worldwide basis. The aim of this study was to assess the presence of depression, anxiety, and asthma-related quality of life in patients with asthma and to evaluate their impact on severity and control of asthma. Methods: We assessed the severity of asthma by comparing patients' current medications to GINA guideline. The patients were classified into the controlled group (asthma patients with controlled disease) or into the uncontrolled group (asthma patients with uncontrolled disease), which included partly controlled and uncontrolled patients, again based on GINA guideline 2004. Patient-reported depressive symptoms, anxiety, and asthma-related quality of life were evaluated using the Beck Depression Inventory (BDI), the State-Trait Anxiety Inventory (STAI), and Korean asthma quality of life (KAQLQ). Results: One hundred and twenty patients were enrolled (mean age, $55{\pm}1$ years; 65% women). Among the 120 patients, 14 (12%) patients were classified as having mild asthma, 88 (73%) as having moderate asthma, and 18 (15%) as having severe asthma. Eighty-one (67%) of the 120 patients were controlled. The asthma-related quality of life showed the difference according to severity of asthma (p=0.002). The prevalence of depression was lower (10% vs 26%, p=0.024) and the asthma-related quality of life was higher (59.951 (29~75) vs 35.103 (18~72), $p{\leq}0.001$) in the controlled group. Higher trait anxiety score and lower asthma-related quality of life were associated with depression (p<0.001, p=0.002, respectively). Conclusion: Psychological factors, such as anxiety and depression, are strongly associated with asthma control. Therefore, screening and management of depression is needed in patients with asthma.

The purpose of this study was to investigate the association between antioxidant food intake pattern and asthma control status in Korean adolescents. This study was conducted using data from 1,578 patients diagnosed with asthma among the participants in the 11th online health behavior survey. Statistical analyses were performed for sociodemographic variables, known risk factors for asthma worsening, and all variables which were related to food intake pattern. For final decision, logistic regression analysis was used to estimate the associations between antioxidant food intake and asthma worsening. Male gender and smoking experiences were associated with asthma exacerbation. Low intake of antioxidant foods status also significantly increased asthma exacerbations. Antioxidant food intake and smoking prevention education is important for adolescent asthma patients. It is highly needed to recommend taking fruits and vegetables properly.

Background: In asthma, consistent control of chronic airway inflammation is crucial, and the use of asthma-controller medication has been emphasized. Our purpose in this study is to compare the incidence of acute exacerbation and healthcare costs related to the use of asthma-controller medication. Methods: By using data collected by the National Health Insurance Review and Assessment Service, we compared one-year clinical outcomes and medical costs from July 2014 to June 2015 (follow-up period) between two groups of patients with asthma who received different prescriptions for recommended asthma-controller medication (inhaled corticosteroids or leukotriene receptor antagonists) at least once from July 2013 to June 2014 (assessment period). Results: There were 51,757 patients who satisfied our inclusion criteria. Among them, 13,702 patients (26.5%) were prescribed a recommended asthma-controller medication during the assessment period. In patients using a recommended asthma-controller medication, the frequency of acute exacerbations decreased in the follow-up period, from 2.7% to 1.1%. The total medical costs of the controller group decreased during the follow-up period compared to the assessment period, from $3,772,692 to $1,985,475. Only 50.9% of patients in the controller group used healthcare services in the follow-up period, and the use of asthma-controller medication decreased in the follow-up period. Conclusion: Overall, patients using a recommended asthma-controller medication showed decreased acute exacerbation and reduced total healthcare cost by half.

This study investigates the effects of occupational asthma and rhinitis on job performance in order to maintain the health of bakery workers and to increase manufacturing productivity. Hotel bakery workers, small bakery businesses, bakery franchises and bakeries in large discount stores, located in Seoul, Kyungki and Incheon were sampled for the study over the period of December 1 to 15, 2008. A total of 245 samples were used for the final analysis. To verify the hypothesis established for the study, we conducted frequency analysis, factorial analysis, reliability analysis, correlation analysis and regression analysis using SPSS 12.0, a statistical package, to derive a conclusion. As a result of this study, it turned out that occupational asthma and rhinitis in bakery workers does affect job performance as well as motivating the intention to quit job. It is recommended that in order to increase the job performance of bakery workers and reduce their desire to quit job, their work environment should be improved and that training about occupational asthma and rhinitis should be provided for the prevention and reduction of disease.

Purpose: This review aimed to evaluate the effectiveness of telemonitoring (TM) in the management of children and adolescents with asthma. Methods: We searched Ovid-MEDLINE, Ovid-EMBASE, CENTRAL (Cochrane Central Register of Controlled Trials), CINAHL (Cumulative Index to Nursing and Allied Health Literature), and 5 domestic databases to identify randomized controlled trials (RCTs) published through December 2017. Two reviewers independently selected relevant studies, assessed methodological quality and extracted data. We performed a meta-analysis of TM versus usual care and summarized the intervention characteristics of included studies. Results: Of the 3,095 articles identified, 8 RCTs (9 articles) were included in this review. The type of TM intervention of included studies was varying across studies (transmitted data, transmission frequency, data review, etc.). The pooled asthma control score was not significantly different between TM and usual care (standardized mean difference 0.04, 95% confidence interval (CI) -0.20~0.28). Another pooled analysis demonstrated no statistically significant difference in asthma exacerbation between TM and usual care (odds ratio 0.95, 95% CI 0.43~2.09). Overall, the pooled results from these studies revealed that TM did not lead to clinically significant improvements in health outcomes, but some studies in our analysis suggested that TM increased patient medication adherence and intervention adherence. Conclusion: The current evidence base does not demonstrate any differences between TM intervention and usual care, but TM intervention might be considered a promising strategy for the delivery of self-management support for children and adolescents with asthma. Further well-designed studies are needed to assess the effects on clinical outcomes.

Purpose: Fractional exhaled nitric oxide (FeNO) and forced expiratory flow between 25% and 75% of vital capacity ($FEF_{25-75}$) are not included in routine monitoring of asthma control. We observed changes in FeNO level and $FEF_{25-75}$ after FeNO-based treatment with inhaled corticosteroid (ICS) in children with controlled asthma (CA). Methods: We recruited 148 children with asthma (age, 8 to 16 years) who had maintained asthma control and normal forced expiratory volume in the first second ($FEV_1$) without control medication for ${\geq}3$ months. Patients with FeNO levels >25 ppb were allocated to the ICS-treated (FeNO-based management) or untreated group (guideline-based management). Changes in spirometric values and FeNO levels from baseline were evaluated after 6 weeks. Results: Ninety-three patients had FeNO levels >25 ppb. These patients had lower $FEF_{25-75}$ % predicted values than those with FeNO levels ${\leq}25$ ppb (P<0.01). After 6 weeks, the geometric mean (GM) FeNO level in the ICS-treated group was 45% lower than the baseline value, and the mean percent increase in $FEF_{25-75}$ was 18.7% which was greater than that in other spirometric values. There was a negative correlation between percent changes in $FEF_{25-75}$ and FeNO (r=-0.368, P=0.001). In contrast, the GM FeNO and spirometric values were not significantly different from the baseline values in the untreated group. Conclusion: The anti-inflammatory treatment simultaneously improved the FeNO levels and $FEF_{25-75}$ in CA patients when their FeNO levels were >25 ppb.

Objectives: This study was performed to examine the relationship between health behaviors, living environment, and asthma in adolescents in Korea. Methods: Information on adolescents' characteristics, including demographic factors, health behaviors, and doctor's diagnosis of asthma was obtained from the Korean Youth Risk Behavior Web-based Survey (2015). In total, 68,043 middle and high school students participated. Environmental characteristics, including city park area and outdoor PM₁₀ concentrations in 2015 were obtained from the Korean Statistical Information Service. The adolescents' and environmental characteristics were merged by local information. Multiple logistic regression models were used to investigate the risk factors affecting asthma in adolescents. Results: The prevalence of asthma in adolescents in 2015 was 8.8%. In the multiple logistic regression analysis, adolescents who were male, attended middle school, suffered obesity, experienced tobacco smoking, had physical activity levels of 2 to 4 days, had higher stress levels, and lived in areas with outdoor PM₁₀ concentrations more than 47 ㎍/㎥ were more likely to have asthma, while adolescents who had middle levels of family economic status were less likely to do so. Conclusions: The fact that PM₁₀ concentration can affect asthma is an important point in this study. Risk factors identified in this study could be used as basic data for the prevention and management of asthma in Korea.

Purpose: This study was conducted to develop a respiratory nursing program using recorder playing for patients with asthma and to determine the effects of the program. Method: Participants were 26 patients with asthma (experimental group: 13, control group: 13). The experimental group participated in the respiratory nursing program for six months from April, to October, 2007. Content included playing a recorder, group education about asthma, and educational messages including cellular phone messages. The control group received usual care during the six months. Results: In this research the respiratory nursing program using recorders was developed in 3 stages: initial stage, advanced stage, and wrap up stage. Compared to the control group, fatigue status in the experimental group improved significantly as well as level of forced expiratory volume in 1 second. However significant differences were found in sleep status, mood, or quality of life. Conclusions: These results suggest that this respiratory nursing program for symptom management of patients with asthma led to improvements in self care activity. Nursing interventions are needed to maintain and further enhance the quality of life of these patients and the interventions should be implemented over a transition period.

Intraoperative delivery of salbutamol (${\beta}_2$ agonist) through a breathing circuit may be performed in asthma patient. A 28-year-old woman with a history of asthma was diagnosed with chronic sinusitis and bilateral nasal polyps, and an endoscopic sinus surgery was performed. The patient was recommended salbutamol nebulization every 4 hours during the perioperative period because of the risk of asthma attack. At the end of the operation, when salbutamol was sprayed through the tube before extubation and the connector tip went inside the tube during injection. The patient was immediately referred to the pulmonary medicine department for bronchoscopy, where the foreign body was removed safely without any complications. When general anesthesia is performed on a patient who usually uses an inhaler for asthma, caution is required because the tip that connects the inhaler and the breathing circuit can aspirate into the endotracheal tube and enter the lungs when applying the inhaler before waking up the patient.
