Abstract Background: As a multisystem infectious disease, there is inflammation, which causes an increase in brucellosis. The red cell distribution width (RDW) has been identified as markers of inflammation. The present study aimed to investigate the predictive contribution value of RDW in the diagnosis of brucellosis.Methods: Medical records of 398 patients with brucellosis and 398 age-matched and gender-matched healthy controls in a single center from January 2017 to December 2019 were retrospectively reviewed.Results: The mean age of brucellosis patients was 47.1±12.9 years. The RDW levels were significantly higher in brucellosis group when compared to the control group (p < 0.001); The RDW levels were markedly lower in brucellosis male patients(14.32±2.15%)when compared to the brucellosis female patient(s 15.41±3.13%)(t= -9.56, p < 0.001). The biochemical markers of brucellosis patients included erythrocyte, hemoglobin, HCT, corpuscular volume, hemoglobin, hemoglobin concentration were all negatively correlated with RDW (r = −0.227, -0.383, -0.266, -0.253, -0.311 and -0.225, all p < 0.001). The values of hemoglobin (β coefficient = -0.084, p < 0.001), ESR (β coefficient = -0.020, p = 0.004) were significantly and independently correlated with RDW. Receiver operating characteristic (ROC) curve analysis showed that the best cutoff point for RDW in the diagnosis of brucellosis was 13.45%, which evaluated brucellosis with a sensitivity of 64.1% and a specificity of 83.9%. The area under the ROC curve for RDW was calculated as 0.80 (95% CI 0.769–0.831, P<0.001).Conclusion: This study revealed that the RDW in diagnosing brucellosis had a higher sensitivity and specificity. RDW values may be useful complementary indirect markers for the diagnosis of brucellosis.

Abstract Objective: To explore the value of mean corpuscular hemoglobin concentration (MCHC) and red cell distribution width (RDW) for overall survival (OS) and progression-free survival (PFS) in patients with pancreatic cancer (PC) who underwent radical pancreatomy.Background: Inflammatory factors are important factors in promoting the occurrence and metastasis of malignant tumors. RDW and MCHC are suggested to be relevant to the prognosis of several malignancies. Such as gastric cancer, colon cancer. However, there are few studies to explore the correlation between them and PC.Methods: This study included 532 patients with PC who underwent radical resection between March 2011 and May 2019. Kaplan-Meier curve method and Cox proportional hazard regression model were applied to analyze prognosis. Correlations between categorical variables were analyzed using Chi squared tests.Results: Survival curve showed that OS and PFS were significantly favorable for resectable PC patients with high preoperative MCHC (P=0.02) (P=0.005), RDW in the normal range (P<0.001) (P<0.001). Multivariate analysis suggested that MCHC (HR: 0.612, 95%CI: 0.426-0.879, P=0.008), and RDW (HR: 3.969, 95%CI: 2.952-5.338, P<0.001) were independent prognostic factors for resectable PC patients. MCHC (HR: 0.657, 95%CI: 0.458-0.943, P=0.023), RDW (HR: 3.915, 95%CI: 2.923-5.243, P < 0.001) were also independent recurrent factors for resectable PC patients. Correlation analysis showed that MCHC was related to tumor size, nerve invasion, and anemia-related indicators, meanwhile RDW was connected with carcinoma-embryonic antigen (CEA) and carbohydrate antigen199 (CA19-9).Conclusion: The preoperative MCHC and RDW were simple and convenient predictive factors for prognosis and progression of patients with PC.

Background: The ratio of hemoglobin to red cell distribution width (HRR) has been described as an effective prognostic factor in several types of cancer. The aim of this study was to investigate the prognostic role of preoperative HRR in resected-lung-adenocarcinoma patients. Methods: We enrolled 342 consecutive patients. Age, sex, surgical resection, adjuvant treatments, pathological stage, preoperative hemoglobin, red cell distribution width, and their ratio were recorded for each patient. Results: Mean age was 66 years (SD: 9.0). There were 163 females (47.1%); 169 patients (49.4%) had tumors at stage I, 71 (20.8%) at stage II, and 102 (29.8%) at stage III. In total, 318 patients (93.0%) underwent lobectomy, and 24 (7.0%) pneumonectomy. Disease-free survival multivariable analysis disclosed an increased hazard ratio (HR) of relapse for preoperative HRR lower than 1.01 (HR = 2.20, 95%CI: (1.30–3.72), p = 0.004), as well as for N1 single-node (HR = 2.55, 95%CI: (1.33–4.90), p = 0.005) and multiple-level lymph node involvement compared to N0 for both N1 (HR = 9.16, 95%CI:(3.65–23.0), p < 0.001) and N2 (HR = 10.5, 95%CI:(3.44–32.2, p < 0.001). Conclusion: Pre-operative HRR is an effective prognostic factor of disease-free survival in resected-lung-adenocarcinoma patients, together with the level of pathologic node involvement.
