Currently, the European Society of Cardiology recommends sodium-glucose co-transporter 2 inhibitors in patients with type 2 diabetes mellitus and heart failure or at high risk for heart failure, as a first choice in drug naïve patients, or as a second drug if the patient is already on metformin. The aim of our study is to review the current state of knowledge about the position of metformin in the treatment of patients with type 2 diabetes mellitus and heart failure.Selenium (Se) supplements are commonly prescribed to autoimmune thyroiditis (AIT) patients by European endocrinologists, despite the lack of official guidelines. The majority of Europe is depleted of natural Se sources, and the daily population intake does not comply with recommended values. Optimal individual plasma Se concentration is reached when the selenoproteins (selenoprotein P, glutathione peroxidase) are fully saturated. However, Se intake has to be regulated because both Se shortage and overdose negatively impact health. In the case of AIT, Se may alleviate symptoms or prevent progression to hypothyroidism and postpartum hypothyroidism. Se supplementation in euthyroid, subclinical, or overt hypothyroid AIT patients decreased thyroid autoantibodies, lowered or maintained the TSH level, decreased the fT4/fT3 ratio, reduced the body's oxidative stress and inflammatory status, and amended quality of life and thyroid ultrasound structure and volume. In pregnant females, adequate Se intake protected them ach to Se supplementation. This article presents a comprehensive review of recent randomised-controlled trials, meta-analyses, and clinical trials concerning the risks and benefits of Se supplementation in different clinical settings and specific populations with particular emphasis on AIT in a practical manner.Papillary thyroid carcinoma (PTC) has an excellent prognosis with a relatively low mortality rate, but a small portion of PTC patients suffer from an aggressive form of the disease. In such cases early detection of lymph node metastasis (LNM) is as paramount as it is problematic. The routine use of central neck lymph node dissection is not recommended. New methods to detect LNM are needed. MicroRNAs are a potential biomarker for diagnosis and prognosis of PTC. In this review we summarise the current knowledge regarding dysregulated miRNAs and their association with LNM in PTS patients. The PubMed and EBSCO databases were searched using terms for "microRNA", "thyroid carcinoma", and "prognosis" by using Boolean operators. Based on eligibility and exclusion criteria, articles were screened and reviewed in full, methodological data of included studies were extracted, and risk of bias analysis performed. In total, 446 unique studies were extracted from the mentioned databases, and based on inclusion and exclusion criteria 27 studies were included in this review. Of them 17 analysed tissue microRNAs, 5 analysed circulating microRNAs, and 5 studies analysed both tissue and circulating samples. MiRNA-146B, miRNA-221, miRNA-222, miRNA-21, miRNA-204, miRNA-451, miRNA-199a-3p, and miRNA-30a-3p were dysregulated in at least 2 separate studies. A sizable portion of studies failed to show statistically significant differences in miRNA expression between LNM-positive and -negative patients. Different methodologies and disparities of patient populations could explain these discrepancies.\ This research supports the statement that specific up- and downregulated miRNAs are associated with LNM in PTC patients. However, the prognostic value of these miRNAs is limited. Additional targeted cohort studies are required to elucidate the role of miRNAs in defining individualised treatment strategies for thyroid cancer patients.Genetic conditions, traumatic injuries, carious lesions and periodontal diseases are all responsible for dental pathologies. The current clinical approaches are based on the substitution of damaged dental tissues with inert materials, which, however, do not ensure full physiological recovery of the teeth. Different populations of dental mesenchymal stem cells have been isolated from dental tissues and several attempts have already been made at using these stem cells for the regeneration of human dental tissues. Despite encouraging progresses, dental regenerative therapies are very far from any clinical applications. This is tightly connected with the absence of proper platforms that would model and faithfully mimic human dental tissues in their complexity. Therefore, in the last decades, many efforts have been dedicated for the development of innovative systems capable of emulating human tooth physiology in vitro. this website This review focuses on the use of in vitro culture systems, such as bioreactors and "organ-on-a-chip" microfluidic devices, for the modelling of human dental tissues and their potential use for dental regeneration and drug testing.The assessment of local blood flow patterns in patients with peripheral arterial disease is clinically relevant, since these patterns are related to atherosclerotic disease progression and loss of patency in stents placed in peripheral arteries, through mechanisms such as recirculating flow and low wall shear stress (WSS). However, imaging of vascular flow in these patients is technically challenging due to the often complex flow patterns that occur near atherosclerotic lesions. While several flow quantification techniques have been developed that could improve the outcomes of vascular interventions, accurate 2D or 3D blood flow quantification is not yet used in clinical practice. This article provides an overview of several important topics that concern the quantification of blood flow in patients with peripheral arterial disease. The hemodynamic mechanisms involved in the development of atherosclerosis and the current clinical practice in the diagnosis of this disease are discussed, showing the unmet need for improved and validated flow quantification techniques in daily clinical practice. This discussion is followed by a showcase of state-of-the-art blood flow quantification techniques and how these could be used before, during and after treatment of stenotic lesions to improve clinical outcomes. These techniques include novel ultrasound-based methods, Phase-Contrast Magnetic Resonance Imaging (PC-MRI) and Computational Fluid Dynamics (CFD). The last section discusses future perspectives, with advanced (hybrid) imaging techniques and artificial intelligence, including the implementation of these techniques in clinical practice.
