Blood urea nitrogen and serum albumin levels are independent risk factors for poor clinical outcome in CAP. However, there is a paucity in the literature on the role of Blood urea nitrogen and albumin ratio(B/A) in CAP. This was a prospective observational study in which 112 admitted patients with the diagnosis of CAP underwent routine blood examinations, ABG, procalcitonin and Chest X-ray. Univariate analysis among various risk factors, CURB-65 scores, blood parameters including B/A ratios and clinical outcomes were carried out followed by multiple logistic regression. Cox regression was done to look at B/A values and time to mortality. In the logistic regression, age, CURB -65 score, B/A ratio and procalcitonin came out to be independent risk factors for ICU admission and mortality. Odds ratio of B/A in predicting mortality and ICU admission came out to be 67.8 (49.2-95.4) and 11.2 (8.4-14), respectively. Cox regression showed B/A values were also found to have a statistically significant relationship with time to mortality (p=0.001). B/A ratio has the potential to become a veritable predictor of poor clinical outcomes in patients with CAP.

Objectives: Acute ischemic stroke (AIS) is one of the most important and major causes of mortality worldwide. In AIS patients, the blood urea nitrogen to creatinine ratio (B/C ratio) was investigated as a dehydrated biomarker in previous studies. However, the B/C ratio can be affected by medications and past medical history. We hypothesized addition of serum albumin, which has been shown to have beneficial neuroprotective effects, could compensate for the disadvantages. In the present study, the BUN to serum albumin ratio (B/A ratio) was evaluated association with AIS patient’s prognosis. Methods: This retrospective cohort study of AIS in our hospital was conducted from February 2018 through June 2020. First, demographic and clinical data were collected and compared with the prevalence of mortality and ICU admission. Then, the B/C ratio and the B/A ratio were calculated. Differences in the performance between the B/C ratio and the B/A ratio for outcome prediction were evaluated based on the area under the curve of the receiver operating characteristic (AUROC). Results: Among the 1,164 patients enrolled in this study, 77 (6.6%) died during hospitalization and 467 (40.1%) were admitted to ICU. Multivariate logistic regression had shown that the B/A ratio was a significant predictor of mortality and admission to ICU. In addition, the B/A ratio was significantly higher in ICU-admitted patients and non-survivors. The AUROC of the B/A ratio was 0.687 and the B/C ratio was 0.533 for predicting mortality; the B/A ratio was statistically superior to the B/C ratio. For predicting ICU admission, the AUROC values of the B/A ratio and the B/C ratio were 0.567 and 0.556, respectively, and a statistically significant difference was not observed. Conclusion: The B/A ratio is a simple and useful tool for predicting the outcomes of ischemic stroke patients.

Abstract Background: There is an increasing incidence of Pneumocystis pneumonia among individuals without the human immunodeficiency virus (HIV) infection (non-HIV Pneumocystis pneumonia). However, the prognostic factors for patients with non-HIV Pneumocystis pneumonia have not been identified. Moreover, A-DROP (for classifying the severity of community-acquired pneumonia) or the blood urea nitrogen-to-serum albumin ratio, which is reported to be predictor of mortality of community-acquired pneumonia, has not been established as an efficient prognostic factor in patients with non-HIV Pneumocystis pneumonia. In this study, we analyzed the prognostic factors for non-HIV Pneumocystis pneumonia and evaluated the effectiveness of A-DROP and the blood urea nitrogen-to-serum albumin ratio as prognostic factors.Methods: This retrospective study involved a chart review of the medical records of 102 patients diagnosed with non-HIV Pneumocystis pneumonia between January 2003 and May 2019 at five medical facilities. Prognostic factors associated with the 30-day mortality were assessed using multiple logistic regression analysis.Results: Among the 102 patients with non-HIV Pneumocystis pneumonia, 46 (45.1%) had autoimmune diseases, 19 (18.6%) had hematological malignancies, 18 (17.7%) had solid malignancies, and 19 (18.6%) had other diseases. The 30-day mortality rate for non-HIV Pneumocystis pneumonia was 20.5% in this study population. Compared with survivors, non-survivors had significantly lower serum albumin levels and a significantly higher age, corticosteroid dosage at the onset of Pneumocystis pneumonia, alveolar–arterial oxygen gradient, A-DROP score, lactate dehydrogenase levels, blood urea nitrogen levels, and blood urea nitrogen-to-serum albumin ratio. The results of multivariate analysis showed that a high A-DROP score and blood urea nitrogen-to-serum albumin ratio at treatment initiation were significantly associated with the 30-day mortality risk.Conclusions: A high A-DROP score and blood urea nitrogen-to-serum albumin ratio at treatment initiation are independent prognostic predictors of mortality risk in patients with non-HIV Pneumocystis pneumonia.

Abstract Objective The aim of this study was to identify early warning signs for severe coronavirus disease 2019 (COVID-19). Methods We retrospectively analysed the clinical data of 90 patients with COVID-19 from Guanggu District of Hubei Women and Children Medical and Healthcare Center, comprising 60 mild cases and 30 severe cases. The demographic data, underlying diseases, clinical manifestations and laboratory blood test results were compared between the two groups. The cutoff values were determined by receiver operating characteristic curve analysis. Logistic regression analysis was performed to identify the independent risk factors for severe COVID-19. Results The patients with mild and severe COVID-19 had significant differences in terms of cancer incidence, age, pretreatment neutrophil-to-lymphocyte ratio (NLR), and pretreatment C-reactive protein-to-albumin ratio (CAR) ( P =0.000; P =0.008; P=0.000; P =0.000). The severity of COVID-19 was positively correlated with comorbid cancer, age, NLR, and CAR ( P <0.005). Multivariate logistic regression analysis showed that age, the NLR and the CAR were independent risk factors for severe COVID-19 (OR=1.086, P =0.008; OR=1.512, P =0.007; OR=17.652, P =0.001). Conclusion An increased CAR can serve as an early warning sign of severe COVID-19 in conjunction with the NLR and age.

Background. Sepsis is a leading cause of mortality among severe burns. This study was conducted to investigate the predictive role of C-reactive protein-to-albumin ratio (CAR) for sepsis and prognosis in severe burns. Methods. Patients with severe burn injuries from 2013 to 2017 were enrolled and divided into septic and nonseptic groups based on the presence of sepsis within 30 days postburn. Independent risk factors for sepsis were performed by the univariate and multivariate logistic regression analyses. The association between CAR level at admission and postburn 30-day mortality was designed via the Kaplan–Meier method. Results. Of all the 196 enrolled patients, 83 patients developed sepsis within 30 days postburn injury, with an incidence of 42.3%. TBSA percentage (OR: 1.65, 95% CI: 1.17-2.32, P = 0.014 ) and CAR at admission (OR: 2.25, 95% CI: 1.33-3.56, P = 0.009 ) were the two independent risk factors for sepsis in severe burns by the multivariate logistic regression analysis. A higher CAR level (≥1.66) at admission was associated with a lower postburn 30-day survival rate ( P = 0.005 ). Conclusions. The CAR level at admission was an independent risk factor for sepsis and prognosis in severe burns.
