Introduction: Diabetic nephropathy (DN) is a disease that progresses with the slow and progressive decline of the glomerular filtration rate (GFR); the installation of this pathology is silent and one of the major causes of death in patients with diabetes.
Aims: To identify new molecular biomarkers for early identification of the onset of DN in patients with type II diabetes (DM2). We studied the expression profile of the genes; (), () and () in peripheral blood and urine sediment samples.
Methods: Ninety volunteers, 51 with DM2 and 39 healthy, were recruited from the Faculdade de Medicina do ABC outpatient clinic. We conducted an interview and collected anthropometric data, as well as blood and urine samples for biochemical evaluation and real-time PCR amplification of the genes of interest.
Results: Gene expression data: peripheral blood (DM2 0.09758±0.1914 vs CTL 0.02293±0.04578), (blood: DM2 0.01102±0.04059* vs CTL 0.0001317±0.0003609; urine: DM2 0.7195±2.344* vs CTL 0.09812±0.4755), there was no significant expression of COLIV1A. These genes demonstrated good sensitivity and specificity in the receiving operating characteristic curve evaluation.
Conclusion: Our data suggest the potential use of and gene expression in peripheral blood and urine samples as early biomarkers of DN.

Malignant peripheral nerve sheath tumors (MPNSTs) are aggressive sarcomas and the primary cause of mortality in patients with neurofibromatosis type 1 (NF1). These malignancies develop within preexisting benign lesions called plexiform neurofibromas (PNs). PNs are solely driven by biallelic loss eliciting RAS pathway activation, and they respond favorably to MEK inhibitor therapy.

Allogeneic hematopoietic cell transplantation (HCT) is a curative therapy limited by graft-versus-host disease (GVHD). In preclinical studies and early-phase clinical studies enrichment of donor regulatory T cells (Tregs) appears to prevent GVHD and promote healthy immunity.We enrolled 44 patients on an open-label, single-center, phase 2 efficacy study investigating if a precision selected and highly purified Treg cell therapy manufactured from donor mobilized peripheral blood improves one-year GVHD-free relapse free survival (GRFS) after myeloablative conditioning (trial NCT01660607).

Leukemia symptoms occurring in the first 4 weeks of infancy are known as congenital leukemia. We present a case of congenital leukemia in a full-term neonate manifesting at birth with a grossly distended abdomen due to a large abdominal mass. Ultrasonography of the abdomen showed a large abdominal mass originating from the liver.

This study analyzes the prognostic factors of thrombosis in patients with hematological diseases after peripherally inserted central catheter (PICC) surgery. We conducted a retrospective analysis of 223 patients with hematological diseases who underwent PICC catheterization between January 2017 and June 2021. These patients were categorized into the thrombotic group and non-thrombotic group based on the occurrence of thrombosis following PICC catheterization.
