Background: Eosinophilic pleural effusion (EPE) is an eosinophil count more than 10% on cytology of pleural samples. Recently, it was reported that malignancy had been the most prevalent cause inducing EPE. Therefore, we conducted an analysis on the prevalence and etiology of EPE and investigated the relationship between EPE and malignancy. Materials and Methods: Data for pleural cell differential count from patients receiving thoracentesis during the period from January 2008 to December 2013 were compared with clinical data and established diagnosis of patients obtained via electronic chart review. Results: A total of 6,801 requests of pleural cytology from 3,942 patients with pleural effusion who had received thoracentesis were available at Far Eastern Memorial Hospital from 2008 to 2013, and of these subjects, 115 (2.9%) were found to have EPE. The most frequent cause of EPE was malignancy (33.0%, n=38), followed by parapneumonic effusions (27.8%, n=32), tuberculosis pleuritis (13.9%, n=16), transudate effusions (12.2%, n=14) and the presence of blood or air in pleural space (10.4%, n=12). Additionally, an inverse relationship of eosinophilia in pleural fluid was identified in patients with malignancy and EPE. The cut-off eosinophil count in pleural fluid was 15% for the most accurate discrimination between malignancy and benign disorders in patients with EPE. At the cut-off level, the sensitivity and specificity were 65.8% and 67.5%, respectively. Conclusions: Pleural fluid eosinophilia was a speculative negative predictor for malignancy, despite the fact that cancers, including lung cancers and metastatic cancers to lung, were the most leading cause of pleural fluid eosinophilia. An inverse correlation was observed between the pleural eosinophil percentage and the likelihood of malignancy in patients with EPE.

Environmental Performance Evaluation(EPE) is a key process of Corporate Environmental Management. This paper presents the results of an empirical survey on the status of current practices in EPE of Korean firms. Based on a corporate environmental management(CEM) model, which is initially developed by Hibbitt and Kamp-Roelands(2001) and modified in terms of EPE, the survey is peformed on the population of Korean firms, which are composed of firms certified as "environmentally friendly" by Korean government and/or certified under Is014001, and compares its results with those of Europe's. Although the relatively low response rate and some methodological limitations makes us be cautious about the interpretation, the results shows many interesting aspects of the current states of Korean firms' EPE practices. That is, the levels of EPE implementation in the environmentally-leading companies of Korea are almost the same as that of European companies, I. e., in the-final-part-of-developing-stage (3rd stage) level of the CEM model. It is also shown that as In Europe's case, Korean firms are also moving slower in external relationships than in internal control and management, are more developed in the parameters like environmental policy, Internal control, Information system, which are requirements of certification under Is014001, than in parameters like life cycle analysis and full cost accounting, which requires more research efforts, etc.orts, etc.

In this study, we conducted a comparative life cycle assessment (LCA) of two different products, considering reusable and single-use packaging for fresh food distribution. For reusable packaging, we utilized expanded polyethylene (EPE), while for comparison, a disposable box made of widely used expanded polystyrene (EPS) was selected. We comprehensively analyzed the environmental impacts of production, transportation, reprocessing (for reused boxes), and disposal across 18 impact categories. Upon analyzing the actual reuse of 300 rounds of fresh food, the cumulative global warming potential (GWP) values for the EPE box were found to be 280.21 kg carbon dioxide (CO₂) eq, demonstrating a significant 75% reduction compared to those of the EPS box. Furthermore, it was observed that the GWP values for the EPE boxes became equivalent to those of the EPS boxes after 12 rounds of reuse. In conclusion, reusable packaging shows substantial potential to contribute to the reduction of environmental burdens, aligning well with global environmental requirements for sustainable food distribution and related industries.

Background: This study comparatively evaluated the effects of equipment-based pilates exercises (EPE) and lumbar stability exercises (LSE) in patients with chronic low back pain in terms of their Visual Analogue Scale(VAS), Oswestry Disability Index(ODI), and abdominal muscle thickness. Methods: A total of 30 participants were recruited and randomly assigned to either the EPE or the LSE. The VAS, ODI, and abdominal muscle thicknesses of the participants were measured before and after the intervention. Results: The EPE were more effective in terms of the duration of a sustained reduction in VAS scores. post hoc test revealed that EPE were more efficacious in terms of a sustained improvement in ODI scores. With respect to changes in abdominal muscle thickness, there was a significant difference in the thickness of internal oblique muscles(IO) and the external oblique muscles(EO) between the two groups. Conclusion: In this study, both types of exercise interventions resulted in improvements in the VAS, ODI scores, and abdominal muscle thickness in patients with chronic low back pain. However, EPE were found to be more effective than LPE in terms of longer sustained improvements in VAS and ODI scores. Also, with respect to abdominal muscle thickness, the thickness of EO and IO improved only in the EPE group.

This study was performed to investigate the enhancement of immunomodulatory activities of Lithospermum erythrorhizon by extreme process. The extracts are WE100 (water extract for 24 hours at $100^{\circ}C$), WE80 (water extract for 24 hours at $80^{\circ}C$), EE (70% ethyl alcohol extract for 24 hours at $80^{\circ}C$) and EPE (extreme process for 30 minutes at $25^{\circ}C$, 500 MPa after 70% ethyl alcohol extracts for 3 hours at 40, 50, $60^{\circ}C$). Extraction yield was increased up to 5~10% by extreme process, compare to the normal extraction such as water solvent extraction, 70% ethyl alcohol solvent extraction. The cytotoxicity of the extracts was showed in the range of 12.68~15.89% at $1.0mg/m{\ell}$ for human lung cell (HEL299). The EPE40 was showed the lowest cytotoxicity 12.68%. The EPE60 extracted by extreme process increased the growth of human B and T cells up to $12.12{\times}10^4\;cells/m{\ell}$ and $14.88{\times}10^4\;cells/m{\ell}$, respectively and the EPE60 greatly increased the cytokine secretion of both IL-6 and TNF-${\alpha}$. The extracts by extreme process also exhibited higher levels of nitric oxide production from macrophages than the lipopolysaccaharides. It can be concluded that Lithospermum erythrorhizon has immune activities and The extreme process could increase higher immune activities possibly by immunomodulatory compounds.

Eosinophilic pleural effusion (EPE) is defined as a pleural effusion that contains at least 10% eosinophils. EPE occurs due to a variety of causes such as blood or air in the pleural space, infection, malignancy, or an autoimmune disease. Undifferentiated connective tissue disease (UCTD) associated with eosinophilic pleural effusion is a rare condition generally characterized by the presence of the signs and symptoms but not fulfilling the existing classification criteria. We report a case involving a 67-year-old man with UCTD and EPE, who has been successfully treated with a single intrapleural corticosteroid injection.

Purpose: To retrospectively determine whether specialized magnetic resonance imaging (MRI) reading performed by an experienced radiologist affected the successful assessment of extraprostatic extension (EPE) in the presence of biopsy-related hemorrhage after prostate biopsy. Materials and Methods: Two hundred consecutive patients with biopsy-proven prostate cancer underwent MRI. General radiologist and subspecialized radiologist readings were unpaired and reviewed in random order by a radiologist who was blinded to patients' clinical details and histopathologic data. The extent of hemorrhage was assessed on T1-weighted (T1W) MRI using a 1-4 scale, and the likelihood of EPE was assessed for each of the four categories. Histopathologic specimens served as the reference standard. The area under the curve (AUC) of the standard reading was compared to that of the specialized reading. Results: Post-biopsy hemorrhage was subjectively graded as ≥ 3 in 101 patients (50.5%) by standard reading, and in 100 patients (50.0%) by specialized reading. The standard and specialized readings disagreed for 40 (20.7%) of the patients (kappa [κ] = 0.35; 95% CI, 0.14-0.48). Of these, specialized reading was the correct interpretation for 21 patients (52.5%). The sensitivity (75% vs. 44%; P = 0.002) and area under the receiver operating characteristics (AUROC) (0.83 vs. 0.67; P = 0.008) of the specialized readings were significantly higher than those of the standard readings, while there was no significant difference in specificity (84% vs. 87%; P = 0.434). Conclusion: The reinterpretation of MRI by experienced radiologists significantly improves the diagnosis of EPE in prostate cancer in the presence of post-biopsy hemorrhage.

Eosinophilic pleural effusions (EPE) are defined as those effusions that contain at least 10% eosinophils, and EPE can be associated with peripheral blood eosinophilia in a variety of systemic diseases. There have been a few cases that have addressed the association of peripheral blood eosinophilia and posttraumatic EPE, and this condition can be misdiagnosed as being the result of other causes due to the delayed presentation. We report here on a case of 47-year-old male who presented with eosinophilic pleural effusion associated with peripheral blood eosinophilia at 2 months after minor chest trauma. We excluded the other possible causes such as consumption of drugs, parasite infection, malignancy, diseases of pulmonary eosinophilic infiltration, autoimmune diseases and pulmonary thromboembolism. We observed his clinical course without specific treatment. Three months later, the pleural effusion completely disappeared and the number of peripheral eosinophils returned to normal.
