Background: Acute respiratory distress syndrome (ARDS) is related to high mortality and morbidity. There are no proven therapeutic measures however, to improve the clinical course of ARDS, except using low tidal volume ventilation. Metformin is known to have pleiotropic effects including anti-inflammatory activity. We hypothesized that pre-admission metformin might alter the progress of ARDS among intensive care unit (ICU) patients with diabetes mellitus (DM). Methods: We performed a retrospective cohort study from January 1, 2005, to April 30, 2005 of patients who were admitted to the medical ICU at Seoul National University Hospital because of ARDS, and reviewed ARDS patients with DM. Metformin use was defined as prescribed within 3-month pre-admission. Results: Of 558 patients diagnosed with ARDS, 128 (23.3%) patients had diabetes and 33 patients were treated with metformin monotherapy or in combination with other antidiabetic medications. Demographic characteristics, cause of ARDS, and comorbid conditions (except chronic kidney disease) were not different between metformin users and nonusers. Several severity indexes of ARDS were similar in both groups. The 30-day mortality was 42.42% in metformin users and 55.32% in metformin nonusers. On multivariable regression analysis, use of metformin was not significantly related to a reduced 30-day mortality (adjusted β-coefficient, -0.19; 95% confidence interval, -1.76 to 1.39; p=0.816). Propensity score-matched analyses showed similar results. Conclusion: Pre-admission metformin use was not associated with reduced 30-day mortality among ARDS patients with DM in our medical ICU.

Background: Multiple comorbidities related to chronic obstructive pulmonary disease (COPD) make it a difficult disease to treat. The relationship between these comorbidities and COPD has not been fully investigated. We aimed to determine whether COPD was independently associated with various comorbidities. Methods: This was a cross-sectional study, which used data from the Korean National Health and Nutrition Examination Survey (KNHANES) V conducted between 2010 and 2012. Survey design analysis was employed to determine the association between COPD and 15 comorbidities. A COPD patient was defined as a smoker with forced expiratory volume in one second (FEV1)/forced vital capacity (FVC) <0.7 and comorbidities were defined based on objective laboratory findings and questionnaires. Results: Of a total of 9488 patient who underwent spirometry, 744 (7.84%) COPD cases and 3313 non-COPD controls were included in the analyses. Although the prevalence rates of the majority of the comorbidities were high among the COPD patients, only hypertension (adjusted odds ratio [aOR], 1.63; 95% CI, 1.13-2.33 in Stage 1 COPD group; aOR, 1.92; 95% CI, 1.36-2.72 in Stage 2-4 COPD group) and a history of pulmonary tuberculosis (aOR, 3.38; 95% CI, 1.90-5.99 in Stage 2-4 COPD group) were independently associated with COPD after adjustment for age, smoking status, and confounders. Conclusions: Only hypertension and a history of pulmonary tuberculosis were independently associated with COPD after adjustment for confounders among 15 comorbidities. The results suggest that majority of COPD patients might have similar risk factors with its comorbidities, including age and smoking status.

본 연구는 히터팬 처리에 의한 시설환경 개선 및 참외의 품질 및 수량성을 검정코자 수행하였다. 히터팬 처리에 따른 2017년 1월 1일부터 31일간 터널내부의 일평균 온도는 무처리구의 17.8℃에 비하여 히터팬 처리구에서는 18.7℃로 히터팬 처리구에서 0.9℃ 더 높았다. 작물이 자라고 있는 지상 20㎝ 부위의 풍속은 무처리구의 0.05m·s<SUP>-1</SUP>에 비해 히터팬 처리구에서 0.24m·s<SUP>-1</SUP>로 4.8배 높았고 온도는 무처리구의 35.3℃에 비해 히터팬 처리구에서는 40.9℃로 히터팬 처리구에서 5.6℃ 더 높았으나 습도는 무처리구의 39.1%에 비해 8.1%P 더 낮았다. 정식 51일후 개화율 조사에서 무처리구의 91%에 비하여 히터팬 처리구에서는 96%로 5%P 더 높았고, 첫 수확소요일수도 무처리구의 86일에 비해 4일 단축되었다. 과중은 무처리구의 339.7g에 비하여 히터팬 처리구에서 15.1g 더 무거웠고 상품과율도 90.4%에 비하여 3.4%P 더 많았으며 10a당 상품수량도 142.9㎏에 비하여 38% 더 증가하여 95% 수준에서 통계적 유의성이 인정되었다. 이상의 결과를 종합 하면 히터팬 처리로 시설내 온도상승은 물론 공기의 유동이 활발하여 작물생육에 유리하고 수확시기가 단축되고 품질이 향상되고 수량이 증가하는 것을 알 수 있었다. The purpose of this study was to investigate the changes of environmental conditions and the quality and yield of melon fruit by heat fan operation in greenhouses at winter season. The average daily temperature inside the tunnels during January 1 to 31, 2017 was 0.9℃ higher than that of the control 17.8℃. The air flow rate of heater fan treatment was 4.8 times higher than the control (untreated 0.05 m·s<SUP>-1</SUP>) at 20㎝ above the ground where the korean melon grew. The temperature of the heater pan was 5.6℃ higher than that of the untreated at 35.3℃ and the relative humidity was 8.1% lower than that of the untreated at 39.1%. The flowering rate of the heater fan treatment was 96%, 5% higher than the control. The number of first harvest days of heater fan treatment was shortened by 4 days than that of untreated treatment. Fruit quality and marketable fruit yield increased by 3.4% and 38% compared to untreated respectively, the heater fan treatment increased the temperature inside the greenhouse and air flow rete, which were beneficial for growing the korean melon in greenhouses at winter season.
