Clinical and Hematological Predictors for Return of Spontaneous Circulation in Patients With Out-of-Hospital Cardiac Arrest.

Background: To investigate the association of clinical and hematological parameters with return of spontaneous circulation (ROSC) in out-of-hospital cardiac arrest (OHCA).

Methods: Clinical data of successive non-traumatic adult OHCA patients with available laboratory data of complete blood count and peripheral blood smear at emergency department (ED) arrival were requested. Hematological parameters were collected and calculated, and logistic regression and survival analysis were performed for association of ROSC with the parameters.

Clinical Significance of Smudge Cells in Peripheral Blood Smears in Hematological Malignancies and Other Diseases.

Background: It is reported that the percentage of smudge cells in the blood smear could be a prognostic indicator in chronic lymphocytic leukemia. However, the clinical significance of smudge cells in other hematological malignancies, solid tumors or non-malignant diseases is less clear. Hence, this study was conducted to survey the clinical significance of smudge cells in hematological cancers and other disorders.

Eosinophilia in Pleural Effusions: a Speculative Negative Predictor for Malignancy.

Background: Eosinophilic pleural effusion (EPE) is an eosinophil count more than 10% on cytology of pleural samples. Recently, it was reported that malignancy had been the most prevalent cause inducing EPE. Therefore, we conducted an analysis on the prevalence and etiology of EPE and investigated the relationship between EPE and malignancy.
