OBJECTIVES: In patients referred to off-pump coronary artery bypass grafting, pulmonary vein isolation (PVI) may be used for those with persistent atrial fibrillation (AF), an alternative to the Maze procedure. However, the success rate of PVI in persistent AF is limited. The study assesses the prognostic value of focal epicardial electrocardiography of the pulmonary veins (PVs) for surgical ablation results. METHODS: We mapped 140 PV in 35 cases undergoing off-pump coronary artery bypass grafting...

Background: Progressive multifocal leukoencephalopathy (PML) is a severe demyelinating disease caused by the polyomavirus JC (JCV) affecting subjects with impaired immune system. While JCV-DNA detection in cerebrospinal fluid (CSF) is diagnostic of PML, the clinical significance of plasma JCV-DNA is still uncertain. Methods: We retrospectively analyzed plasma samples drawn from patients with PML close to disease onset, and controls without PML. In PML patients, we compared plasma JCV DNA detection and levels to: JCV DNA in the other biological samples, clinical and laboratory parameters and patients' survival...

Background: In kidney transplant recipients, anticardiolipin (ACL) antibodies without antiphospholipid syndrome (APS) are found in up to 38% of patients and could be associated with thrombotic events (TEs). However, the prognostic role of ACL regarding kidney transplant and patients outcomes have still not been well defined. Methods: We conducted an observational, monocentric, retrospective cohort study including 446 kidney transplant recipients and standardized follow-up: 36-month allograft and patient survival, 12-month estimated glomerular filtration rate (eGFR) and 3- and 12-month screening biopsies...

Genome insertions and deletions (indels) show tremendous functional impacts despite they are much less common than single nucleotide variants, which are at the center of studies assessing cancer mutational signatures. We studied 8,891 tumor samples of 32 types from The Cancer Genome Atlas in order to explore those genes which are potentially implicated in cancer indels. Survival analysis identified in-frame indels as the most important variants predicting adverse outcome. Transcriptome-wide association study identified 16 genes overexpressed in both tumor samples and tumor types with high number of in-frame indels, of whom four (APOBEC1, BCL2L15, FOXL1, and PDX1) were identified with gene products distributed within the nucleus...

We previously reported six different p53 isoforms in renal cell carcinoma (RCC). In the present study, influences of p53β on recurrence-free survival (RFS) and overall survival (OS) were evaluated. Patients diagnosed with RCC in our center were into this study. mRNA expressions of p53 isoforms (p53α, p53β, p53γ) in tumors were determined by RT-PCR and real-time PCR. Functional yeast-based assay was performed to analyze p53 mutational status. p53β transfected 786-O and CAKi-1 cells were cultured to examine expressions of B-cell lymphoma 2-associated X protein (bax) and caspase-3, and ratios of apoptosis...

Identifying a reliable biomarker may accelerate diagnosis of multiple sclerosis (MS) and lead to early management of the disease. Accumulating evidence suggest that cerebrospinal fluid (CSF) and peripheral blood concentration of osteopontin (OPN) may have diagnostic and prognostic value in MS. We conducted a systematic review and meta-analysis of studies that measured peripheral blood and CSF levels of OPN in MS patients and controls to evaluate the diagnostic potential of this biomarker better. We searched PubMed, Web of Science and Scopus databases to find articles that measured OPN concentration in peripheral blood and CSF samples from MS patients up to October 19, 2016...

Endoscopic ultrasonography-guided fine-needle aspiration (EUS-FNA) has been applied to pancreatic lesions since the 1990s, and its use is now widespread. Improvements in endoscopic devices and sampling techniques have resulted in excellent diagnostic ability for solid pancreatic lesions. However, clinical improvements alone are not responsible for it; pathological aspects have also played important roles. Rapid on-site evaluation minimizes endoscopic procedures, although its value at improving the diagnostic ratio is still debated...

Immune checkpoint inhibitor therapy has been clinically introduced for several malignancies, and its effectiveness has been confirmed by clinical trials. In particular, programmed cell death protein 1 (PD-1) and programmed death-ligand 1 (PD-L1) are widely known as important immune checkpoint molecules associated with the mechanisms of immune escape by malignant tumor cells. On the other hand, liquid biopsy of blood specimens has the clinical benefit of providing a simple, repeatable sampling tool. Non-invasive liquid biopsy has recently been spotlighted as a promising approach to predicting tumor progression and prognosis...

Squamous cell carcinoma of the head and neck, SCCHN, is a heterogeneous group of tumours not only concerning site of origin but also regarding aetiology. The 5-year survival for the whole group of SCCHN tumours has not significantly improved over the last 20-25 years. Apart from tumour spread to lymph nodes, N status, gains and losses of specific chromosomes are the only factors shown to be independent prognostic markers for these tumours. Worldwide an increasing number of people ? 40 years are seen being affected by tongue SCC, the most common tumour within the SCCHN group...

CD73, also known as ecto-5'-nucleotidase (eN, NT5E, EC3.13.5), is the rate-limiting enzyme for adenosine generation and is expressed on multiple cells. Its expression is significantly influenced by hypoxia and inflammatory factors. During inflammation, CD73 protects endothelial barrier function and inhibits leukocyte trafficking. CD73 also promotes M2 macrophages (anti-inflammatory phenotype). In addition, CD73 is expressed on Treg cells and mediates immune suppression through adenosine. CD73 serves as an essential regulator for the immunity and inflammation...

Breast cancer (BC) is the second most common cause of cancer-related deaths in women worldwide. The availability of reliable biomarkers of response/resistance to cancer treatments would benefit patients and clinicians allowing for a better selection of BC patients most likely to respond to a specific treatment. Phosphatidylinositol 3-kinase (PI3K) enzymes are involved in numerous cellular- functions and processes. The gene encoding for PI3K catalytic subunit p110α is mutated in 20-40% of BC. We performed a meta-analysis of the current literature on randomized clinical trials, investigating the role of PIK3CA mutational status as prognostic factor and predictor of response to anti-cancer treatments...

Hypoalbuminaemia has been previously described to predict worse non-relapse mortality (NRM) and inferior overall survival (OS) in allogeneic haematopoietic cell transplant (allo-HCT) recipients. Here, we evaluate the role of hypoalbuminaemia (<35 g/l) at time of onset of acute graft-versus-host disease (aGVHD) when incorporated into the refined aGVHD score. The study population consisted of 522 patients, median age 53 (18-75) years, who underwent an allo-HCT mostly for haematological malignancies. Standard risk (SR) aGVHD comprised 467 patients (89%) and the number of high risk (HR) cases was 55 (11%)...

Nestin is an intermediate filament protein and a stem cell marker expressed in several tumours. There is growing evidence of an association between the expression level of nestin and the pathogenesis of triple-negative breast cancer (TNBC). Nestin is also expressed in newly forming tumour vessels and is a valuable marker of ongoing angiogenesis. In this study, we aimed to evaluate the prognostic value of nestin expression in breast tumour cells and to determine whether this expression influences angiogenesis...

Glioblastoma (GBM) is the most common type of malignant brain tumor. In spite of recent advancements in surgical techniques, chemotherapy, and radiation therapy, patients with GBM often face a dire prognosis. MicroRNAs have been shown to modulate the aggressiveness of various cancers, and have emerged as possible therapeutic agents for the management of GBM. miR‑205 is dysregulated in glioma and act as a prognostic indicator. However, the role of miR‑205 in the development of GBM has not been elucidated...

Vascular endothelial growth factor C (VEGFC) stimulates leukemia cell proliferation and survival, and promotes angiogenesis. We studied VEGFC expression in bone marrow samples from 353 adult acute myeloid leukemia (AML) patients and its relationship with several clinical, cytogenetic, and molecular variables. We also studied the expression of 84 genes involved in VEGF signaling in 24 patients. We found that VEGFC expression was higher in AML patients with myelodysplasia-related changes (AML-MRC) than in patients with non-AML-MRC...
