Starting from the metabolic profile of type 2 diabetes mellitus (T2DM), we hypothesized that the mechanisms of ¹³¹I-induced cardiotoxicity differ between patients diagnosed with differentiated thyroid cancer (DTC) with/without T2DM, with metformin potentially acting as a cardioprotective agent by mitigating inflammation in patients with T2DM. To address this hypothesis, we quantified, using ELISA, the serum concentration of several key biomarkers that reflect cardiac injury (NT-proBNP, NT-proANP, ST2/IL-33R, and cTn I) in 74 female patients with DTC/-T2DM and 25 with DTC/+T2DM treated with metformin. All patients received a cumulative oral dose of I exceeding 150 mCi (5.

Background: Traditional thoracotomy, an invasive surgical procedure, has been the standard approach for extended lobectomy in treating non-small cell lung cancer (NSCLC). However, minimally invasive surgery (MIS) has gained traction with advancements in surgical techniques. Despite this, the outcomes of extended lobectomy via a minimally invasive approach remain largely uncharted.

No clinical studies have investigated the effect of radioiodine (I)-targeted therapy on the neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) as inflammatory response markers in patients with differentiated thyroid cancer (DTC) associated with type 2 diabetes mellitus (T2DM) and obesity. This study aimed to assess the relationship between blood radioactivity, body mass index (BMI), and peripheral blood cells three days after I intake in 56 female patients without T2DM (DTC/-T2DM) vs. 24 female patients with T2DM (DTC/+T2DM).

Radioiodine (131I) therapy for differentiated thyroid cancer (DTC) involves exposure of the whole body, including the heart, to ionizing radiation. This exposure to the subsequent risk of heart disease is uncertain, especially in patients with DTC associated with type 2 diabetes mellitus (DTC/+T2DM). The current study aimed to assess the relationship between left ventricular ejection fraction (LVEF), high cumulative 131I dose, and peripheral blood parameters in patients with DTC/−T2DM and DTC/+T2DM.

Publications investigating the effect of radioactive iodine (131I) therapy on the circulating peripheral blood cells in patients with differentiated thyroid cancer (DTC) are limited to blood samples collected more than 92 h after 131I. Studies conducted on blood samples collected up to 92 h are rare due to the radioactive contamination risk. This research aimed to assess the relationship between the prescribed 131I activity, human whole blood activity, and peripheral blood cells at many time points (6, 22, 46, 69, and 92 h after 131I).

Autoimmune thyroiditis (AIT) may impair radioiodine (I) uptake in papillary thyroid cancer (PTC). Finding the mechanisms that govern immune cells during I therapy of PTC with concomitant AIT (PTC + AIT) could provide a rationale. Our study aimed to evaluate the effects of I on anti-thyroglobulin antibodies (TgAb), matrix metalloproteinase-9 (MMP-9) and its tissue inhibitor TIMP-1 and tumor necrosis factor-α (TNF-α) and its receptors TNFR1 and TNFR2, in PTC and PTC + AIT patients.

Matrix-metalloproteinases (MMPs) and their tissue inhibitors (TIMPs) expression levels have been demonstrated to have prognostic value in oral squamous cell carcinoma (OSCC). The present study hypothesized that melatonin, a small lipophilic molecule primarily secreted by the pineal gland, may be able to regulate MMP activity in OSCC progression. This study aimed to investigate the associations between melatonin, MMPs, TIMPs and the histopathological characteristics of patients with OSCC.

Cytokines in heart failure.

Adv Clin Chem

December 2019

Department of Carcinogenesis and Molecular Biology, Institute of Oncology Bucharest, Bucharest, Romania. Electronic address:

The natural history of heart failure (HF) is not linear, because changes in the heart structure and function start long before the disease becomes clinically evident. Many different cytokines originating from intracardiac tissues (cardiomyocytes, cardiac endothelial cells, cardiac fibroblasts, and cardiac infiltrated immune cells) or extracardiac tissues (adipose tissue, gut, and lymphoid organs) have been identified in HF. Because the levels of circulating cytokines correlate with the development and severity of HF, these mediators may have both pathophysiological importance, through their ability to modulate inflammation, myocyte stress/stretch, myocyte injury and apoptosis, fibroblast activation and extracellular matrix remodeling, and utility as clinical predictive biomarkers.

Deficient antibody production in patients with common variable immunodeficiency (CVID) is accompanied by an inability to produce free light chains (FLCs), particularly kappa (κ) FLC, due to B-cell dysfunction. We found that intravenous immunoglobulin (IVIg) administration, in a patient with CVID and (κ) FLC deficiency, for o short period of only 6 months, induced after discontinuation of treatment some kind of "long-lasting active immunity", leading to the secretion of immunoglobulin (κ) FLCs. A remarkable finding of our study is how effectively IVIg therapy led to a calculable (κ/λ) FLCs ratio, within the reference range.

The aim of this study is to identify the appropriate preoperative evaluation methods for the quality of the skin flaps and subcutaneous breast layer using different imaging techniques in correlation with the intraoperative findings and also their importance for the outcome in immediate implant-based breast reconstruction. Clinical evaluation, mammography, breast ultrasound and breast MRI were used for the assessment of the mastectomy skin flaps which enhanced the selection of the adequate surgical technique for breast reconstruction. The evaluation started with the skin flap measurement of 50 patients with breast cancer, who were candidates for modified radical mastectomy (MRM) in 2014, using the above-mentioned methods, without immediate breast reconstruction.

Purpose: Heart failure (HF) is considered to be a complex syndrome associated with neurohormonal and cytokine activation, that contribute to its progression. There are evidences which showed that, carbohydrate antigen 125 (CA 125), a tumor marker widely used for ovarian cancer therapy monitoring, was significantly elevated in HF patients. We hypothesized that inflammatory stimuli may be responsible for amino-terminal fragment of the prohormone B-type natriuretic peptide (NT-proBNP) and CA-125 production and release in chronic HF (CHF).

Purpose: Signaling pathways involved in electrical, structural and contractile remodeling processes behind development and progression of atrial fibrillation (AF) have not been completely elucidated, but it seems to be related to complex interactions among neurohormonal and cellular mediators. We aimed to investigate interleukin-6 (IL-6), transforming growth factor-beta1 (TGF-β1), matrix metalloproteinase-9 (MMP-9), tissue inhibitor of metalloproteinase-1 (TIMP-1), as biomarkers of atrial remodeling, in patients with paroxysmal and persistent AF, and their correlation with N-terminal prohormone of brain natriuretic peptide (NT-proBNP) and left atrial (LA) diameter.

Methods: Thirty-seven patients (22M/15F) with paroxysmal AF, 32 patients (22M/10F) with persistent AF and 30 healthy control subjects (18M/12F) were enrolled in the study.

b First Department of Obstetrics and Gynecology , Semmelweis University, Budapest , Hungary.

Primary antibody deficiency syndromes are a rare group of disorders present at any age, with complex polygenic disorders. We report the forth case of polyglandular autoimmune syndrome (PAS) type IIIc worldwide with complex clinical features and no family history of endocrine disorders or primary immunodeficiencies. Our patient, a 44-year-old Caucasian female was diagnosed with PAS type IIIc due to the presence of autoimmune thyroiditis, autoimmune alopecia diffusa and primary ovarian insufficiency, associated with lymphoproliferative disease and primary antibody failure.

Objectives: Patritumab is a fully human anti-human epidermal growth factor receptor 3 (HER3) antibody that blocks activation by its ligand, heregulin (HRG). Preclinical studies have demonstrated the efficacy of patritumab in aberrantly high HRG-expressing non-small cell lung cancer (NSCLC). In the phase II randomized, placebo-controlled double-blind study HERALD (n=212 patients with NSCLC), patritumab plus erlotinib did not improve progression-free survival (PFS) compared with placebo plus erlotinib.
