The purpose of this study was to identify factors that influence the functional status of chronic lung disease patients. Method: A descriptive, correlational study design was used. The study was conducted at the outpatient respiratory clinic of the large university hospital in Korea. A convenience sample of 128 chronic lung patients (age = 64.2 yrs; 106 COPD, 17 bronchiectasis, 5 DILD) with mean FEV1 64.4 % predicted. Functional status was measured with SIP. Physical variables (FEV1% predicted, dyspnea, fatigue, pulmonary symptom distress), psychological variables (mood, stress), and situational variable (sleep quality) were examined. Dyspnea was measured by the BDI, fatigue was measured with the MFI. Mood was measured with the modified Korean version of POMS. Sleep quality was measured with the Pittsburgh Sleep Quality Index. Potential independent variables for the regression were age, gender, years since diagnosis, FEV1% predicted, dyspnea, fatigue, pulmonary symptom distress, stress, and sleep quality. Result: In general, functional status was relatively good. In regression analysis, functional status were significantly influenced by dyspnea, mood, age and fatigue. These variables explained 70 % of the variances in functional status. Conclusion: The results suggest that psychophysiologic symptom management should be a focus to enhance the functional status in this group.

Purpose: The purpose of this study was to identify the factors influencing Symptoms of Stress in patients with chronic illness. Method: Data were collected by questionnaires from 1,748 patients with chronic disease in General Hospital in Seoul. Chronic diseases of were cardiac disease including hypertension, peptic ulcer, pulmonary disease included COPD and asthma, DM, and chronic kidney disease. The data were analyzed using descriptive statistics, pearson correlation coefficients, and stepwise multiple regression. Result: 1. The level of symptoms of stress was moderate(M=2.17). 2. The score of symptoms of stress showed significantly positive correlation with the score of mood state(r=.58, p=.00), perceived stress(r=.57, p=.00), and ways of coping(r=.33, p=.00). The symptoms of stress showed significantly negative correlation with the score of social support(r=-.37, p=.00) and self-esteem(r=-.19, p=.00). 3. The most powerful predictor of symptoms of stress was mood state and the variance explained was 34%. A combination of mood state, ways of coping, perceived stress, social support, and duration of illness account for 45% of the variance in symptoms of stress of the patients with chronic illness. Conclusion: This study suggest that mood state, ways of coping, perceived stress, and social support are significantly influencing factors on symptoms of stress of the patients with chronic illness.

Purpose : This study was implemented to identify the risk conditions influencing suicidal ideation in a nationally representative sample of elderly South Koreans. Methods : Data from 1,152 men and 1,581 women aged 65 years or older were gathered from the 2013 and 2014 Korea National Health and Nutrition Examination Survey VI. All analyses were performed using SPSS. To determine significant correlations between risk condition and suicidal ideation, a t-test was used. Results : There were differences in suicidal ideation according to the following individual factors: age, educational background, marital status, economic activity, recognition of stress, experience of depression, and economic status. There were differences in suicidal ideation according to the following health-related factors: subjective health status, EQ-5D (EuroQoL-5 Dimensions), hours of sleep, and BMI. There were also differences in suicidal ideation according to the following disease-related factors: HTN, COPD, asthma, stroke, depression and osteoarthritis. Conclusion : The findings indicate that broad intervention programs should be distributed to prevent suicidal ideation. It is also recommended that programs be developed in a way that can help manage the variables identified in this study. Furthermore, follow-up studies should be conducted to verify the program.

Purpose: The purpose of this study was to investigate the activity of respiratory muscle and lung capacity during deep breathing with electrical stimulation of the vagus nerve. Methods: This study was conducted on 30 healthy adults in their 20s. Subjects were randomly performed to deep breathing or deep breathing with vagus nerve electrical stimulation. All subjects' diaphragm and internal oblique muscle activity were measured during deep breathing by electromyography, and lung capacity was measured by spirometry immediately after beep breathing. In the vagus nerve stimulation method, the surface electrode was cut into the left ear and then electrically stimulated using a needle electric stimulator. Results: The activity of diaphragm was significantly increased in deep breathing with vagus nerve electrical stimulation than in deep breathing. However, lung capacity did not show any significant difference according to the condition. Conclusion: Vagus nerve electrical stimulation could induce diaphragm activity more than deep breathing alone. Deep breathing with vagus nerve electrical stimulation may enhance the activity of the respiratory muscles and is expected to be an effective treatment for the elderly or COPD patients with poor breathing ability.

Background: Small cell lung cancer (SCLC) tends to grow more rapidly and spread much faster than non-small cell lung cancer (NSCLC). A concurrent combination of chemotherapy and thoracic radiotherapy is suggested as the standard conventional treatment, but it is more challenging for elderly patients having pulmonary and cardiovascular comorbidities. Case presentation: Here we present a case of an 80-year-old male, current smoker diagnosed with SCLC in limited stage T3N0M0 (36mm right upper lobe, satellite nodule) in Dec, 2015. The standard concurrent chemoradiotherapy was not available for his comorbidities, which included chronic obstructive pulmonary disease (COPD) and angina pectoris. Furthermore, he and his family refused the recommended chemotherapy or radiotherapy exclusively. Alternatively, he received various non-conventional treatments including local radiofrequency hyperthermia, mistletoe, and Traditional Korean medicine including acupuncture, moxibustion and herbs since Jan. 2016. Despite the progression in primary tumor size, there have been no other distant relapse so far, and the patient has been in stable condition ever since. Conclusion: We suggest that a combination of various alternative treatments could be a candidate for elderly patients intolerable to conventional cytotoxic treatments.

Macrophages residing in various tissue types are unique in terms of their anatomical locations, ontogenies, developmental pathways, gene expression patterns, and immunological functions. Alveolar macrophages (AMs) reside in the alveolar lumen of the lungs and serve as the first line of defense for the respiratory tract. The immunological functions of AMs are implicated in the pathogenesis of various pulmonary diseases such as allergic asthma, chronic obstructive pulmonary disorder (COPD), pulmonary alveolar proteinosis (PAP), viral infection, and bacterial infection. Thus, the molecular mechanisms driving the development and function of AMs have been extensively investigated. In this review article, we discuss the roles of granulocyte-macrophage colony-stimulating factor (GM-CSF) and transforming growth factor (TGF)-β in AM development, and provide an overview of the anti-inflammatory and pro-inflammatory functions of AMs in various contexts. Notably, we examine the relationships between the metabolic status of AMs and their development processes and functions. We hope that this review will provide new information and insight into AM development and function.

The prevalence of respiratory diseases is increasing due to social and environmental factors such as increased environmental pollution and air pollution, and among them, chronic obstructive pulmonary disease (COPD) in particular has a high mortality and morbidity rate worldwide. As a result, medical expenses are rapidly increasing, creating a social and economic burden. In response to this, there is a need to discuss ways to reduce the risk from diseases and manage them appropriately, and the most basic starting point in this process is how these chronic lung disease patients are treated in actual clinical settings and how to improve the quality of treatment. There is a need to look into whether there are effective drugs. Western treatment for chronic obstructive pulmonary disease is basically a disease in which the airway narrows, so bronchodilators are used to widen the bronchi, and corticosteroids and antibiotics are mainly used to relieve the inflammatory response in the lungs. However, since the mainly used Western medicine does not serve as a fundamental therapeutic drug and contains many side effects, there is a need for drugs that improve the quality of life of patients and are more effective in managing symptoms as symptomatic prescriptions. Therefore, Western and Oriental medicine treatments are needed. The purpose is to suggest better treatments through comparative analysis.

This study was designed to construct a structural model for health promoting behavior of patients with chronic disease. The hypothetical model was developed based on the literature review and Pender's health promotion model. Method: Data was collected by questionnaires from 1748 patients with chronic disease in General Hospital from December 1999 to July 2000 in Seoul. The disease of subject were cardiac disease included hypertension peptic ulcer, pulmonary disease included COPD and asthma, DM, and chronic kidney disease. Data analysis was done with SAS 6.12 for descriptive statistics and PC-LISREL 8.13 Program for Covariance structural analysis. Results: 1. The fit of the hypothetical model to the data was moderate, it was modified by excluding 4 path and including free parameters to it. The modified model with path showed a good fitness to the empirical data (χ2=591.83, p<.0001, GFI=0.97, AGFI= 0.94, NNFI=0.95, RMSR=0.01, RMSEA=0.05). 2. The perceived benefits, perceived barriers, self-efficacy, self- esteem, and the plan for action were found to have significant direct effect on health promoting behavior of chronic disease. 3. The health concept, health perception, emotional state, social support were found to have indirect effects on health promoting behavior of chronic disease. Conclusion: The derived model in this study is considered appropriate in explaining and predicting health promoting behavior of patients with chronic disease. Therefore, it can effectively be used as a reference model for further studies and suggested implication in nursing practice.

Inflammatory lung diseases are characterized by chronic inflammation and oxidant/antioxidant imbalance. The sources of the increased oxidative stress in patients with chronic inflammatory lung diseases such as asthma and chronic obstructive pulmonary disease (COPD) derive from the increased burden of inhaled oxidants, and from the increased amounts of reactive oxygen species (ROS) generated by several inflammatory, immune and various structural cells of the airways. Increased levels of ROS produced in the airways is reflected by increased markers of oxidative stress in the airspaces, sputum, breath, lungs and blood in patients with lung diseases. ROS, either directly or via the formation of lipid peroxidation products such as 4-hydroxy-2-nonenal may play a role in enhancing the inflammation through the activation of stress kinases (JNK, MAPK, p38) and redox sensitive transcription factors such as NF-${\kappa}B$ and AP-1. Recent evidences have indicated that oxidative stress and pro-inflammatory mediators can alter nuclear histone acetylation/deacetylation allowing access for transcription factor DNA binding leading to enhanced pro-inflammatory gene expression in various lung cells. Understanding of the mechanisms of redox signaling, NF-${\kappa}B$/AP-1 regulation, the balance between histone acetylation and deacetylation and the release and expression of pro- and anti-inflammatory mediators may lead to the development of novel therapies based on the pharmacological manipulation of antioxidants in lung inflammation and injury. Antioxidants that have effective wide spectrum activity and good bioavailability, thiols or molecules which have dual antioxidant and anti-inflammatory activity, may be potential therapeutic agents which not only protect against the direct injurious effects of oxidants, but may fundamentally alter the underlying inflammatory processes which play an important role in the pathogenesis of chronic inflammatory lung diseases.

A 14-year-old gelded dressage horse weighing 500 kg was presented to the Equine Medical Center of the Seoul Racecourse of Korea Racing Authority (KRA) due to coughing and mucopurulent nasal discharge. The horse was initiated with empirical antibiotic in the first place. However, the clinical signs did not improve but were rather exacerbated even after 3 weeks of therapy. Extensive diagnostic procedures including transtracheal wash (TTW) fluid cytology were undertaken. The localized wheezes and crackles were auscultated and an increase in the amount of mucopurulent exudate in trachea was observed at endoscopy. Infiltration of neutrophils was observed in the TTW fluid cytology implying chronic obstructive pulmonary disease (COPD). Therefore, the systemic glucocorticoid therapy was to be given for 3 weeks with improved ventilation provided at the same time. The respiratory symptoms started to improve in 7 days of therapy and were fully resolved by when the therapy was terminated. The horse is clinically normal now and being monitored for development of any signs of chronic obstructive pulmonary disease.
