Neutrophil-lymphocyte ratio change after curative gastrectomy for gastric cancer: a subgroup analysis
DOI: 10.31744/einstein_journal/2020AO4860
ABSTRACT Objective: To evaluate the impact of neutrophil-lymphocyte ratio change after curative surgery for gastric cancer. Methods: A retrospective analysis of patients with gastric cancer who underwent curative surgery between 2009 and 2017 was performed. A cutoff value was established for the neutrophil-lymphocyte ratio in the pre- and postoperative periods, according to the median value, and four subgroups were formed (low-low/low-high/high-low/high-high). Clinical-pathological and survival data were analyzed and related to these subgroups. Results: A total of 325 patients were included […]

Inflammatory biomarkers in sera of patients with intervertebral disc degeneration
DOI: 10.31744/einstein_journal/2019AO4637
ABSTRACT Objective: To evaluate intervertebral disc levels of inflammatory factor (interleukin 6) and proteinase activity (cathepsin B) in patients with a degenerative disease and serum levels of interleukin 6, serum cathepsin B activity and hyaluronic acid biomarkers. Methods: We conducted immunohistochemistry studies of intervertebral discs to analyze interleukin 6 and cathepsin B levels of patients with degenerative disease and spine fracture (Control Group) and to measure hyaluronic acid, interleukin 6 and cathepsin B activity from sera of intervertebral disc degeneration […]

The cerebrospinal fluid in multiple sclerosis: far beyond the bands
DOI: 10.1590/S1679-45082017RW3706
ABSTRACT The cerebrospinal fluid analysis has been employed for supporting multiple sclerosis diagnosis and ruling out the differential diagnoses. The most classical findings reflect the inflammatory nature of the disease, including mild pleocytosis, mild protein increase, intrathecal synthesis of immunoglobulin G, and, most typically, the presence of oligoclonal bands. In recent years, new biomarkers have emerged in the context of multiple sclerosis. The search for new biomarkers reflect the need of a better evaluation of disease activity, disease progression, and […]
