Objectives: Our aim was to define whether the early granulocyte cell marker (EGC%_DxH) parameter might replace immature granulocytes counts obtained by HematoFlow (IG%_HF) and/or manual differential count (IG%_manual).
Methods: We conducted a study over a 10-day period in February 2014 whereby 402 samples were analyzed for the IG flag. We correlated the EGC%_DxH vs IG%_HF and IG%_manual, identified any discrepant results and finally looked at the impact on our workflow by incorporation of the EGC% into our WBC differential algorithm.
Results: On an initial training set, a receiver operating characteristic (ROC) curve analysis showed a threshold of 0.9% for EGC%_DxH (sensitivity of 91.7%, specificity of 93.5% and an area under the curve of 0.965). Further analysis of the dataset (259 samples) found a correlation of the EGC%_DxH to all our IG% counting methods (r = 0.963). Incorporation of the EGC%_DxH into the WBC HematoFlow differential resulted in a 36% reduction of samples requiring HematoFlow and/or slide review.
Conclusions: The EGC% generated by the DxH 800 can be easily incorporated into existing HematoFlow and slide review algorithms.

Myeloid-derived suppressor cells (MDSCs) are a heterogeneous group of immature myeloid cells playing a critical role in immune suppression. In vitro-generated MDSCs are a convenient tool to study the properties of tumour-associated MDSCs. Here, we compared six protocols for in vitro generation of functional mouse MDSCs from bone marrow progenitors.

Hematological parameters available on automated hematology analyzers have been shown to be useful indicators for hematological disorders. However, extensive studies especially in aplastic anemia for these indices are sparse. Our aim was to investigate the clinical utility of hematological parameters in aplastic anemia.

Problem: Fetal growth restriction (FGR) is a critical pregnancy complication linked to increased perinatal morbidity and mortality. Inflammation plays a key role in FGR's pathophysiology, and systemic inflammation markers may serve as predictors. This study evaluates the role of various inflammation indices; systemic immune-inflammation index (SII), systemic inflammatory response index (SIRI), pan-immune-inflammation value (PIV), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), lymphocyte-to-platelet ratio (LMR), monocyte-to-platelet ratio (MPR), aggregate systemic inflammation index (AISI), systemic coagulation inflammation index (SCII), and immature granulocyte percentage (IG%) in predicting FGR.

Myeloid sarcoma (MS) is an extramedullary localization of immature granulocyte cells that can occur in association with acute myeloid leukemia (AML). Gastrointestinal involvement is relatively common in MS, but exclusive colonic localization is a rare occurrence. Here, we report on a 53-year-old male patient affected by AML developing a severe abdominal pain caused by intestinal perforation requiring surgical intervention.
