- Background
Nutritional status is associated with mortality. The modified Nutrition Risk in the Critically Ill (mNUTRIC) score is one of the most commonly used nutritional risk assessment tools in intensive care units (ICUs). The purpose of this study was to compare the mortality predictive ability of the mNUTRIC score to that of the mNUTRIC-S2 score, which uses the Simplified Acute Physiology Score (SAPS) II instead of the Acute Physiology and Chronic Health Evaluation (APACHE) II. Methods: This retrospective cohort analysis included patients admitted to the ICU between January and September 2020. Each patient’s electronic medical records were reviewed. The model discrimination for predicting ICU mortality was assessed by the area under the receiver operating characteristic (ROC) curve, and a Cox regression model was performed to confirm the relationship between the groups and mortality. Results: In total, 220 patients were enrolled. The ROC curve for predicting ICU mortality was 0.64 for the mNUTRIC score versus 0.67 for the mNUTRIC-S2 score. The difference between the areas was 0.03 (95% confidence interval [CI], –0.01 to 0.06; P=0.09). Patients with mNUTRIC-S2 score ≥5 had a greater risk of ICU mortality (hazard ratio [HR], 3.64; 95% CI, 1.85–7.14; P<0.001); however, no such relationship was observed with mNUTRIC score (HR, 1.69; 95% CI, 0.62–4.62; P=0.31). Conclusions: The mNUTRIC-S2 score was significantly associated with ICU mortality. A cutoff score of 5 was selected as most appropriate.

Abstract
PDFSupplementary Material
- Background
Delayed intubation is associated with poor prognosis in patients with respiratory failure. However, the effect of delayed intubation in patients with idiopathic pulmonary fibrosis (IPF) remains unknown. This study aimed to analyze whether timing of intubation after high-concentration oxygen therapy was associated with worse clinical outcomes in IPF patients. Methods: This retrospective propensity score-matched study enrolled adult patients with IPF who underwent mechanical ventilation between January 2011 and July 2021. Patients were divided into early and delayed intubation groups. Delayed intubation was defined as use of high-concentration oxygen therapy for at least 48 hours before tracheal intubation. The primary outcome was intensive care unit (ICU) mortality, and a conditional logistic regression model was used to evaluate the association between timing of intubation and clinical outcomes. Results: The median duration of high-concentration oxygen therapy before intubation was 0.5 days in the early intubation group (n=60) and 5.1 days in the delayed intubation group (n=36). The ICU mortality rate was 56.7% and 75% in the early and delayed intubation groups, respectively, before propensity matching (P=0.075). After matching for demographic and clinical covariates, 33 matched pairs were selected. In the propensity-matched cohort, delayed intubation significantly increased the risk of ICU mortality (adjusted odds ratio, 3.99; 95% confidence interval, 1.02–15.63; P=0.046). However, in-hospital mortality did not differ significantly between the groups. Conclusions: In patients with IPF, delayed intubation after initiation of high-concentration oxygen therapy was significantly associated with increased risk of ICU mortality compared to early intubation.

Abstract
PDF
- Background
It has been suggested that a high-flow nasal cannula (HFNC) could help to remove carbon dioxide (CO2) from anatomical dead spaces, but evidence to support that is lacking. The objective of this study was to elucidate whether use of an HFNC could reduce the arterial partial pressure of CO2 (PaCO2) in patients with acute hypercapnic respiratory failure who are receiving conventional oxygen (O2) therapy.
Methods A propensity score-matched observational study was conducted to evaluate patients treated with an HFNC for acute hypercapnic respiratory failure from 2015 to 2016. The hypercapnia group was defined as patients with a PaCO2 >50 mm Hg and arterial pH <7.35.
Results Eighteen patients in the hypercapnia group and 177 patients in the nonhypercapnia group were eligible for the present study. Eighteen patients in each group were matched by propensity score. Decreased PaCO2 and consequent pH normalization over time occurred in the hypercapnia group (P=0.002 and P=0.005, respectively). The initial PaCO2 level correlated linearly with PaCO2 removal after the use of an HFNC (R2=0.378, P=0.010). The fraction of inspired O2 used in the intensive care unit was consistently higher for 48 hours in the nonhypercapnia group. Physiological parameters such as respiratory rate and arterial partial pressure of O2 improved over time in both groups.
Conclusions Physiological parameters can improve after the use of an HFNC in patients with acute hypercapnic respiratory failure given low-flow O2 therapy via a facial mask. Further studies are needed to identify which hypercapnic patients might benefit from an HFNC.

Abstract
PDF
- Background
Acute respiratory distress syndrome (ARDS) remains a life-threatening disease. Many patients with ARDS do not recover fully, and progress to terminal lung fibrosis. Angiotensin-converting enzyme (ACE) inhibitor is known to modulate the neurohormonal system to reduce inflammation and to prevent tissue fibrosis. However, the role of ACE inhibitor in the lungs is not well understood. We therefore conducted this study to elucidate the effect of renin-angiotensin system (RAS) blockage on the prognosis of patients with ARDS.
Methods We analyzed medical records of patients who were admitted to the medical intensive care unit (ICU) at a tertiary care hospital from January 2005 to December 2010. ARDS was determined using the Berlin definition. The primary outcome was the mortality rate of ICU. Survival analysis was performed after adjustment using propensity score matching.
Results A total of 182 patients were included in the study. Thirty-seven patients (20.3%) took ACE inhibitor or angiotensin receptor blocker (ARB) during ICU admission, and 145 (79.7%) did not; both groups showed similar severity scores. In the ICU, mortality was 45.9% in the RAS inhibitor group and 58.6% in the non-RAS inhibitor group (P = 0.166). The RAS inhibitor group required a longer duration of mechanical ventilation (29.5 vs. 19.5, P = 0.013) and longer ICU stay (32.1 vs. 20.2 days, P < 0.001). In survival analysis, the RAS inhibitor group showed better survival rates than the non-RAS group (P < 0.001).
Conclusions ACE inhibitor or ARB may have beneficial effect on ARDS patients.

Abstract

- Diffuse alveolar hemorrhage (DAH) is associated with severe outcomes. We report a case of acute respiratory failure that required mechanical ventilation and was clinically and pathologically diagnosed as DAH related to exposure to organic dust. A 39-year-old man, who had visited a warehouse to grade beans for purchase, was referred to our hospital for impending respiratory failure. His initial radiographic examinations revealed diffuse bilateral ground-glass opacities in his lungs and bronchoalveolar lavage resulted in progressively bloodier returns, which is characteristic of DAH. He underwent bedside open lung biopsy of his right lower lobe in the intensive care unit. Biopsy results revealed DAH and organization with accumulation of hemosiderin-laden macrophages and a few fibroblastic foci. The patient was treated with empirical antibiotics and high-dose corticosteroids and successfully weaned from mechanical ventilation. DAH might be considered in the differential diagnosis of patients with acute respiratory failure after exposure to organic particles.
