Purpose: Idiopathic granulomatous mastitis (IGM) is a benign inflammatory breast disease that can clinically mimic breast carcinoma (BC). The aim of this study was to compare the endocan levels between inflammatory and neoplastic diseases of the breast, and to determine whether endocan is a convenient diagnostic biomarker for early stage BC and for the differentiation from IGM.
Material And Methods: A total of 65 patients, consisting of 35 newly diagnosed with BC and 30 with IGM proven by core biopsies, and 20 healthy volunteer women with similar demographic characteristics were enrolled in the study. Endocan was assayed by a commercially available enzyme-linked immunosorbent assay kit.
Results: The endocan level was found to be significantly higher in the BC group than in the control group ( 0.003). Although the endocan level was higher in the IGM group compared to the control group, there was no statistically significant difference ( 0.057). No significant distinctive difference was observed between the BC and IGM groups in terms of the endocan level ( 0.373). The serum endocan level was found to be positively correlated with BMI and vitamin D levels in the BC group ( 0.043 and 0.023, respectively).
Conclusions: We demonstrated that the serum endocan level was increased in patients with BC compared to healthy subjects, whereas in our enrolled study patient population, endocan was not a statistically valid biomarker for the differential diagnosis between BC and IGM. These findings indicate the potential role of endocan in the pathogenesis of BC.

Background: RET variants affecting codon 804 are part of the low-to-moderate risk group in the ATA classification, with indications for prophylactic thyroidectomy beyond age of 5 years. However, aggressiveness seems to be variable. The objective of this study was to report a large cohort of French carriers of a pathogenic variant at codon 804 in the RET proto-oncogene.

Introduction: Despite the efficacy and safety of SARS-CoV-2 vaccines, inflammatory and/or thrombotic episodes have been reported. Since the impact of COVID-19 vaccines on the endothelium remains uncertain, our objective was to assess endothelial activation status before and 90 days after the third dose of the BNT162b2 mRNA COVID-19 vaccine.
Methods: A prospective longitudinal study was conducted at University General Hospital of Albacete, involving 38 healthy health-care workers.
C5a/C5aR regulates Th1/Th2 imbalance in sepsis-associated lung injury by promoting neutrophil activation to increase PAD4 expression.

Department of Emergency, Ruijin Hospital, Shanghai Jiaotong University School of Medicine, Shanghai, China.
Objective: Multi-organ failure frequently complicates sepsis, with lungs being the primary target. T helper (Th) cell activation and phenotypic imbalance among them contribute significantly to sepsis-associated lung injury. Additionally, the complement system could regulate the polarized phenotype of T lymphocytes.

Introduction: The COVID-19 pandemic has promoted an intensive investigation into the pathophysiological mechanisms of SARS-CoV-2 infection, risk factors, and its impact on disease severity. Vitamin D has generated significant attention for its potential role in viral prevention and immune defense due to its pleiotropic functions, including immunomodulation and antimicrobial effects. This study aimed to assess serum 25(OH)D3 levels in patients with COVID-19 compared to those with other viral respiratory infections and to evaluate associations of vitamin D levels with symptomatology, clinical characteristics, presence of comorbidities and laboratory investigation.

Diabetic peripheral neuropathy is a common complication of diabetes mellitus that has dire outcomes, affecting the economic profile of a country. Despite the multifactorial background of the pathogenesis of this disease, the mechanism underlying peripheral neuropathy is still unclear. Endothelial damage is a new determinant of pathogenesis, with endocan as a potential biomarker for endothelial dysfunction in diabetic peripheral neuropathy patients.
