Introduction: Globally, stroke is one of the leading causes of death and disability-adjusted life-years (DALYs). The red cell distribution width (RDW) is a readily available and inexpensive test which is done routinely as a part of complete blood count in these patients.
Objective: In this study, we tried to correlate the RDW with severity of acute ischemic stroke (AIS).
Methods: Patients presenting to emergency department (ED) within 24 hours of the onset of clinical signs and symptoms suggestive of AIS were assessed for Glasgow Coma Scale (GCS) and National Institutes of Health Stroke Scale (NIHSS) score followed by non-contrast computed tomography (NCCT) scan. RDW value for all the patients who were included in the study were co-related with the severity of the stroke.
Results: The median (IQR) RDW in the patients with minor stroke on the basis of GCS was 13.5 (13.3-13.5), moderate stroke was 13.8 (13.5-14.4) and with severe stroke was 15.4 (15.1-15.6) (p < 0.001). The median (IQR) RDW in the patients with minor stroke on the basis of NIHSS score was 13.4 (13.2 - 13.6), moderate stroke was 13.8 (13.5-14.3), and moderate to severe stroke was 14.7 (14.5-15.3) and with severe stroke was 15.5 (15.1-15.7) (p < 0.001). The median RDW in patients who were alive was 13.8 (13.5-15.1) and in patients who expired was 15.5 (14.5-15.7) (p = 0.048).
Conclusion: Based on the findings of this study, RDW index has statistically significant correlation with the severity of AIS. So it can potentially be an important parameter to predict the prognosis of AIS patients.

Background: Diabetes mellitus is a common metabolic disorder, and diabetic erectile dysfunction (DMED) is one of its common complications. The differentiation of the types of erectile dysfunction (ED) is fundamental to treatment, yet there is a lack of simple and efficacious tools for this purpose in clinical practice. In this study, we endeavor to predict ED types using commonly available clinical data from diabetic patients, aiming to develop and assess a risk prediction model for organic erectile dysfunction in individuals with type 2 diabetes.

Objective: To observe how cognitive behavioral intervention affects physical symptoms, B-type Natriuretic Peptide (BNP), Red Cell Distribution Width (RDW), and C-reactive Protein (CRP) in elderly patients with heart failure.
Methods: Convenient sampling method was used to select 98 elderly heart failure patients who visited our hospital from January 2022 to December 2020. Patients were divided into a control group and an observation group using the red and blue ball method, with 49 cases in each group.
Red cell distribution width/platelet ratio predicts decompensation of metabolic dysfunction-associated steatotic liver disease-related compensated advanced chronic liver disease.

Prognostication of compensated advanced chronic liver disease (cACLD) is of paramount importance for the physician-and-patient communication and for rational clinical decisions. The paper published by Dallio reports on red cell distribution width (RDW)/platelet ratio (RPR) as a non-invasive biomarker in predicting decompensation of metabolic dysfunction-associated steatotic liver disease (MASLD)-related cACLD. Differently from other biomarkers and algorithms, RPR is inexpensive and widely available, based on parameters which are included in a complete blood count.

Background: Cardiac arrest (CA) triggers a systemic inflammatory response, resulting in brain and cardiovascular dysfunction. The red blood cell distribution width (RDW)-to-albumin ratio (RAR) has been widely explored in various inflammation-related diseases. However, the predictive value of RAR for the prognosis of CA remains unclear.
