Article Abstract
Background: Previous studies indicated that both red blood cell distribution width (RDW) and neutrophil to lymphocyte ratio (NLR) were useful indices in assessing the disease activity of autoimmune diseases. However, the evidence for the association between RDW, NLR and dermatomyositis (DM) and polymyositis (PM) is limited. The aim of this study is to investigate the association between the disease activity of PM/DM and both RDW and NLR.
Methods: Medical records of 114 PM/DM patients and 114 healthy controls were retrospectively reviewed, and their RDW, NLR and myositis disease activity assessment visual analogue scale (MYOACT) on admission were extracted. The correlations between RDW, NLR and MYOACT were analyzed using the Spearman approach and multivariable model.
Results: PM/DM patients had significantly higher RDW and NLR. Increased RDW in PM/DM patients was not completely attributed to decreased hemoglobin or therapeutic agents. Both RDW and NLR are independently and positively correlated MYOACT.
Conclusion: Both RDW and NLR are useful indices in assessing the disease activity of PM/DM.

Prognostic value and predictive model construction for patients undergoing laparoscopic radical prostatectomy based on the preoperative NPL-IRS score and prognostic nutritional index.

Objective: To explore the prognostic value of preoperative hematological indicators for prostate cancer (PCa) patients with laparoscopic radical prostatectomy (LRP) and construct a nomogram prediction model based on hematological indicators and clinicopathological characteristics.
Method: PCa patients who underwent LRP in Beijing Chaoyang Hospital from January 2017 to December 2022 were retrospectively analyzed. Clinicopathological data and blood indicators, including the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), red blood cell distribution width (RDW), prognosis nutritional index were compared between non-recurrence and recurrence groups.

Objectives: To explore the prognostic value of eight inflammation-nutrition biomarkers in patients with lung cancer and tuberculosis as no multidimensional prognostic models for this comorbid population are available currently.
Methodology: A retrospective study included 100 patients with lung cancer and tuberculosis admitted to a tertiary hospital from October 2019 to October 2024. Eight inflammation-nutrition markers (NLR, PLR, SII, LMR, PNI, HALP, HRR, ALB/GLB) were chosen as predictors while overall survival (OS) was the major event.
Combination of red blood cell distribution width and platelet-to-lymphocyte ratio for predicting severity of diabetic retinopathy.

Aim: To assess and compare the utility of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), systemic inflammation index (SII), and red blood cell distribution width (RDW) as potential biomarkers to predict the severity of diabetic retinopathy (DR) in the United States population.
Methods: The observational study enlisted patients diagnosed with DR from the National Health and Nutrition Examination Survey (NHANES) database, spanning the period from 2005 to 2008. The severity of DR was defined according to Early Treatment for Diabetic Retinopathy Study (ETDRs).

Background/objectives: Environmental stressors, including spaceflight and altered gravity, can negatively affect the symbiotic relationship between the gut microbiome and host health. Dietary prebiotics, which alter components of the gut microbiome, show promise as an effective way to mitigate the negative impacts of stressor exposure. It remains unknown, however, if the stress-protective effects of consuming dietary prebiotics will extend to chronic altered-gravity exposure.
