Purpose of this Mini-Review is to evaluate the role of a thoracic surgeon in the surgical management of retrosternal goitre. A cervical approach is sufficient in the majority of the cases. On the other hand, there are cases where a cervical approach is combined with sternotomy or thoracotomy, depending on the position of the goitre, in the anterior or posterior mediastinum. On top of that, different minimally invasive approaches including video-assisted thoracoscopic surgery (VATS) and robotic-assisted surgery (RATS) have been introduced, providing faster recovery, superior manoeuvrability and better aesthetic results...

BACKGROUND: BioGlue is a commonly used sealant in thoracic surgery. Prolonged air leak and presence of bronchopleural fistulae (BPF) are often encountered in clinical practice. We therefore, investigated the role and the efficacy of BioGlue in these scenarios. METHODS: A systematic review was conducted by searching Medline [1966-2016] and Cochrane Central Register of Controlled Trials (CENTRAL) [1999-2016] along with reference lists of the included studies. Included studies reported on thoracic surgery operations and use of BioGlue in thoracic surgical procedures, whereas excluded studies met at least one of the following criteria: non-English language studies, non-human population, studies on surgical specialties other than Thoracic surgery, reviews and meta-analyses and sealants other than BioGlue...

In this study we analysed a novel tree-growth dataset, inferred from annual ring-width measurements, of 7 forest tree species from 12 mountain regions in Greece, in order to identify tree growth - climate relationships. The tree species of interest were: Abies cephalonica, Abies borisii-regis, Picea abies, Pinus nigra, Pinus sylvestris, Fagus sylvatica and Quercus frainetto growing across a gradient of climate conditions with mean annual temperature ranging from 5.7 to 12.6°C and total annual precipitation from 500 to 950mm...

The investigation of the association between total arterial compliance (CT)-estimated by a novel technique-with left ventricular mass (LVM) and hypertrophy (LVH). Our hypothesis was that CT may be better related to LVM compared to the gold-standard regional aortic stiffness. Within the frame of the ongoing cross-sectional study "SAFAR," 226 subjects with established hypertension or with suspected hypertension underwent blood pressure (BP) assessment, carotid-to-femoral pulse wave velocity (cf-PWV), and echocardiographic measurement of LVM...

REVIEW
Nikolaos G Frangogiannis
The adult mammalian heart has negligible regenerative capacity. Following myocardial infarction, sudden necrosis of cardiomyocytes triggers an intense inflammatory reaction that clears the wound from dead cells and matrix debris, while activating a reparative program. A growing body of evidence suggests that members of the transforming growth factor (TGF)-β family critically regulate the inflammatory and reparative response following infarction. Although all three TGF-β isoforms (TGF-β1, -β2 and -β3) are markedly upregulated in the infarcted myocardium, information on isoform-specific actions is limited...

The early detection of relapse following primary surgery for non-small cell lung cancer and the characterization of emerging subclones seeding metastatic sites might offer new therapeutic approaches to limit tumor recurrence. The potential to non-invasively track tumor evolutionary dynamics in ctDNA of early-stage lung cancer is not established. Here we conduct a tumour-specific phylogenetic approach to ctDNA profiling in the first 100 TRACERx (TRAcking non-small cell lung Cancer Evolution through therapy (Rx)) study participants, including one patient co-recruited to the PEACE (Posthumous Evaluation of Advanced Cancer Environment) post-mortem study...

Background Among patients with non-small-cell lung cancer (NSCLC), data on intratumor heterogeneity and cancer genome evolution have been limited to small retrospective cohorts. We wanted to prospectively investigate intratumor heterogeneity in relation to clinical outcome and to determine the clonal nature of driver events and evolutionary processes in early-stage NSCLC. Methods In this prospective cohort study, we performed multiregion whole-exome sequencing on 100 early-stage NSCLC tumors that had been resected before systemic therapy...

Aims: Cardiac sarcoidosis (CS) is associated with a poor prognosis. Important features of CS include heart failure, conduction abnormalities, and ventricular arrhythmias. Ventricular tachycardia (VT) is often refractory to antiarrhythmic drugs (AAD) and immunosuppression. Catheter ablation has emerged as a treatment option for recurrent VT. However, data on the efficacy and outcomes of VT ablation in this context are sparse. Methods and results: A systematic search was performed on PubMed, EMBASE, and Cochrane database (from inception to September 2016) with included studies providing a minimum of information on CS patients undergoing VT ablation: age, gender, VT cycle length, CS diagnosis criteria, and baseline medications...

Host immunity provides wide spectrum protection that serves to eradicate pathogens and cancer cells, while maintaining self-tolerance and immunological homeostasis. Ligation of the T cell receptor (TCR) by antigen activates signaling pathways that coordinately induce aerobic glycolysis, mitochondrial activity, anabolic metabolism, and T effector cell differentiation. Activation of PI3K, Akt, and mTOR triggers the switch to anabolic metabolism by inducing transcription factors such as Myc and HIF1, and the glucose transporter Glut1, which is pivotal for the increase of glucose uptake after T cell activation...

BACKGROUND: There have been contradicting reports in the literature regarding the impact of pleural fluid aspiration on patients' oxygenation. The aim of this study was to assess the role of the initial size of effusion on post-drainage oxygenation. METHODS: We studied 122 patients, aged (mean±SD) 61.2±16.8 years, with unilateral pleural effusion and no remarkable parenchymal lesion, by determining PaO2, PaCO2 and [A-a] PaO2 just before thoracocentesis (T1), 30 min after its completion (T2) and 48 hours after the procedure (T3)...

A reduction in population sodium (as salt) consumption is a global health priority, as well as one of the most cost-effective strategies to reduce the burden of cardiovascular disease. High potassium intake is also recommended to reduce cardiovascular disease. To establish effective policies for setting targets and monitoring effectiveness within each country, the current level of consumption should be known. Greece lacks data on actual sodium and potassium intake. The aim of the present study was therefore to assess dietary salt (using sodium as biomarker) and potassium intakes in a sample of healthy adults in northern Greece, and to determine whether adherence to a Mediterranean diet is related to different sodium intakes or sodium-to-potassium ratio...

OBJECTIVES: In-vehicle distraction is considered to be an important cause of road accidents. Drivers with Mild Cognitive Impairment (MCI), because of their attenuated cognitive resources, may be vulnerable to the effects of distraction; however, previous relevant research is lacking. The main objective of the current study was to explore the effect of in-vehicle distraction on the driving performance of MCI patients, by assessing their reaction time at unexpected incidents and accident probability...

The conjugation of intracellular glutathione (GSH) with several electrophilic, predominantly hydrophobic, endogenous and xenobiotic compounds, such as chemotherapeutics and carcinogenics, agrochemicals and other drugs, is catalyzed by the multigene enzyme family of glutathione transferases (GSTs). The mammalian family of GSTs comprises three groups: cytosolic, mitochondrial and microsomal. Human cytosolic GSTs constitute the largest family, which is classified in seven distinct classes named Alpha (Α), Mu (M), Pi (P), Theta (T), Sigma (S), Zeta (Z) and Omega (O)...

BACKGROUND: Prosthetic management of thin alveolar ridges in the edentulous mandibles of elderly patients, especially the time of loading, the number of implants needed, and patient expectations and perception, is a challenge in implant dentistry. PURPOSE: Survival of conventionally and immediately loaded 2-piece reduced-diameter implants in the interforaminal region of the edentulous mandible supporting locator-analog attachments was evaluated. Prosthetic complications and peri-implant hygiene were also studied, and patient expectation and subjective evaluation of the treatment were documented...
