Abstract
BACKGROUND Chronic cough is a common respiratory symptom, and, if persistent, the patient's quality of life can worsen and result in a depressive mood, or vice versa. Although previous reports suggest a relationship between chronic cough and depression, we further investigated this relationship according to smoking status and lung function. METHODS This observational study used cross-sectional data from the 6th Korean National Health and Nutrition Examination Survey (2014 and 2016). Propensity score matching using age, sex, smoking status, and lung function was performed for participants with and without chronic cough to reduce the confounding effects associated with depressive mood. Questionnaires recorded coughs persisting for >3 months and the Patient Health Questionnaire-9 (PHQ-9) assessed the severity of depressive mood. RESULTS Among 12 494 participants who were >18 years old, 226 with chronic cough were matched with 226 with non-chronic cough. Overall, chronic cough participants showed higher PHQ-9 scores than the non-chronic cough participants (4.29 ± 5.23 vs. 2.63 ± 3.38, P < .001). When stratified by sex, the difference remained significant in women (5.69 ± 5.96 vs. 3.05 ± 3.97, P < .001) but not in men (3.18 ± 4.27 vs. 2.31 ± 3.65, P = .092). When stratified by lung function status, the difference remained significant for those with normal lung function (4.32 ± 5.32 vs. 2.78 ± 3.86, P = .003) and reduced lung function (4.19 ± 4.93 vs. 2.11 ± 3.55, P ≤ 0.001). Multivariate logistic regression analysis revealed that chronic cough was associated with PHQ-9 score (odds ratio [OR], 1.06; 95% confidence interval [CI], 1.014-1.27, P = .014), chronic obstructive pulmonary disease (OR, 4.87; 95% CI, 1.041-22.86, P = .044) and physician-diagnosed bronchial asthma (OR, 2.93; 95% CI, 1.162-7.435, P = .023). CONCLUSIONS Depressive mood is significantly correlated with chronic cough in females.

Plain language summary
Acute respiratory distress syndrome (ARDS) is a life-threatening condition that commonly develops in patients with sepsis. Patients with ARDS require admission to intensive care and invasive mechanical ventilation. Vitamin B1 and C deficiencies have been reported in critically ill patients with sepsis. Vitamin B1 is involved in aerobic metabolism, and vitamin C has anti-inflammatory and anti-oxidative effects. The aim of this Korean retrospective cohort study was to evaluate the clinical impact of vitamin B1 and C supplementation in patients with sepsis-related ARDS. Patients with ARDS requiring invasive mechanical ventilation, admitted to an intensive care unit (ICU) were included in this study. Clinical outcomes were compared between patients administered with vitamin B1 (200 mg/day) and C (2 g/day) between June 2018-May 2019 (the supplementation group) and those who did not receive vitamin B1 and C administration between June 2017-May 2018 (the control group). Seventy-nine patients were included. Thirty-three patients received vitamin B1 and C, and 46 patients did not. There were no significant differences in the number of deaths between the patients who received vitamin B1 and C and those who did not. The mean number of days not requiring ICU admission or ventilation was greater in patients supplemented with vitamin B1 and C than that in the control patients, but the difference was not statistically significant. Steroid administration was more frequent in patients receiving vitamin B1 and C supplementation than in those without it. The authors concluded that Vitamin B1 and C supplementation at the doses used in this study did not reduce the death rates in ARDS patients.
Abstract
BACKGROUND Although few studies have reported improved clinical outcomes with the administration of vitamin B1 and C in critically ill patients with septic shock or severe pneumonia, its clinical impact on patients with sepsis-related acute respiratory distress syndrome (ARDS) remains unclear. The purpose of this study was to evaluate the association with vitamin B and C supplementation and clinical outcomes in patients with ARDS. METHODS Patients with ARDS requiring invasive mechanical ventilation, admitted to the medical intensive care unit (ICU) were included in this study. Clinical outcomes were compared between patients administered with vitamin B1 (200 mg/day) and C (2 g/day) June 2018-May 2019 (the supplementation group) and those who did not receive vitamin B1 and C administration June 2017-May 2018 (the control group). RESULTS Seventy-nine patients were included. Thirty-three patients received vitamin B1 and C whereas 46 patients did not. Steroid administration was more frequent in patients receiving vitamin B1 and C supplementation than in those without it. There were no significant differences in the mortality between the patients who received vitamin B1 and C and those who did not. There were not significant differences in ventilator and ICU-free days between each of the 21 matched patients. CONCLUSION Vitamin B1 and C supplementation was not associated with reduced mortality rates, and ventilator and ICU-free days in patients with sepsis-related ARDS requiring invasive mechanical ventilation.

Abstract
PURPOSE Body weight fluctuates daily throughout a patient's stay in the intensive care unit (ICU) due to a variety of factors, including fluid balance, nutritional status, type of acute illness, and presence of comorbidities. This study investigated the association between change in body weight and clinical outcomes in critically ill patients during short-term hospitalization in the ICU. METHODS All patients admitted to the Gyeongsang National University hospital between January 2010 and December 2011 who met the inclusion criteria of age 18 or above and ICU hospitalization for at least 2 days were prospectively enrolled in this study. Body weight was measured at admission and daily thereafter using a bed scale. Univariate and multivariate linear and logistic regression analyses were performed to evaluate factors associated with mortality and the association between changes in body weight and clinical outcomes, including duration of mechanical ventilation (MV) use, length of ICU stay, and ICU mortality. RESULTS Of the 140 patients examined, 33 died during ICU hospitalization, yielding an ICU mortality rate of 23.6%. Non-survivors experienced higher rates of severe sepsis and septic shock and greater weight gain than survivors on days 2, 3, 4, 5, and 6 of ICU hospitalization (P < .05). Increase of body weight on days 2 through 7 on ICU admission was correlated with the longer stay of ICU, and increase on days 3 through 7 on ICU admission was correlated with the prolonged use of mechanical ventilation. Increase of body weight on days 3 through 5 on ICU admission was associated with ICU mortality. CONCLUSIONS Increase in body weight of critically ill patients may be correlated with duration of mechanical ventilation use and longer stay of ICU hospitalization and be associated with ICU mortality.
