Reference intervals for reticulocyte count and derived reticulocyte parameters in a cohort of healthy adults.

Introduction: Reticulocyte count and novel derived parameters provide insight into the effectiveness of erythropoiesis and may be useful tools in the classification and diagnosis of anemias. However, there is no standardisation, so we consider it necessary that each laboratory evaluates the parameters according to its own methodology and instrumentation and establishes its own reference ranges. Our aim was to establish the reference intervals (RIs) of reticulocyte profile provided by the Beckman Coulter DxH 900 haematological autoanalyzer in our reference population.

Monocyte distribution width (MDW): study of reference values in blood donors.

Objectives: Monocyte distribution width (MDW) is a new biomarker used as an early indicator of sepsis (ESId). It is often aids in the identification of patients who may develop sepsis. This study aims to establish the MDW reference interval (RI) within the healthy population of blood donors using EDTA-K as anticoagulant.

Monocyte distribution width (MDW) as an infection indicator in severe patients attending in the Emergency Department: a pilot study.

Objective: The aim of the present study was to evaluate the diagnostic performance of monocyte distribution width (MDW) as a biomarker for sepsis diagnosis in severe patients attended in the Emergency Department for different conditions and not only infections.

Methods: We performed an observational study in a consecutive prospective cohort including severe patients attending the Emergency Department with different conditions. MDW and other biomarkers were determined from samples obtained during the first care of patients.

Inactivation of p16 by CpG hypermethylation in renal cell carcinoma.

Objective: Renal carcinoma develops as a consequence of the accumulation of several genetic aberrations. Alterations in the p16 gene have been described in many tumors. Methylation of its promoter in CpG islands is the most common mechanism of inactivation of this gene.

Colorectal carcinoma prognosis can be predicted by alterations in gene p53 exons 5 and 8.

Background And Aims: Gene p53 alteration is a genetic event described in the progression from adenoma to colorectal carcinoma. Most of the p53 mutations occur in exons 5 to 8 in highly preserved regions and in the three main structural domains of the p53 protein. It is possible that mutations affecting different structural regions may present different effects on the p53 protein function and, due to this, they may have different prognostic meaning.
