Risk stratification in patients with advanced chronic heart failure (HF) is an unmet need. Circulating microRNA (miRNA) levels have been proposed as diagnostic and prognostic biomarkers in several diseases including HF. The aims of the present study were to characterize HF-specific miRNA expression profiles and to identify miRNAs with prognostic value in HF patients.

We performed a global miRNome analysis using next-generation sequencing in the plasma of 30 advanced chronic HF patients and of matched healthy controls. selleck chemicals A small subset of miRNAs was validated by real-time PCR (P<0.0008). Pearson's correlation analysis was computed between miRNA expression levels and common HF markers. Multivariate prediction models were exploited to evaluate miRNA profiles' prognostic role. Thirty-two miRNAs were found to be dysregulated between the two groups. Six miRNAs (miR-210-3p, miR-22-5p, miR-22-3p, miR-21-3p, miR-339-3p, and miR-125a-5p) significantly correlated with HF biomarkers, among which N-terminal prohormonle to improve the prognostic stratification of HF patients based on common clinical and laboratory values. Further studies are needed to validate our results in larger populations.
Smoking- and nonsmoking-associated lung cancers have different mechanisms of carcinogenesis. We divided non-small cell lung cancer (NSCLC) patients into nonsmoking and smoking groups with the aim of trying to understand the utility of brain-specific angiogenesis inhibitor 1 (BAI1) expression in the separate groups.

Clinicopathological data were obtained from 148 patients who had undergone surgery for NSCLC of the lung. Tissue microarray blocks were made of samples from NSCLC patients. Two pathologists graded the intensity of BAI1 expression as high or low expression in the cancer cells of patients in the smoking and nonsmoking groups.

NSCLC nonsmokers with higher BAI1 nuclear expression had poor disease-specific survival (DSS) (hazard ratio2.679; 95% confidence interval [CI]1.022-7.022, p=0.045). The Kaplan-Meier survival curve confirmed that higher BAI1 expression was significantly associated with poor DSS (p=0.034) in the nonsmoking group.

We divided NSCLC patients into nonsmoking and smoking groups and found that nuclear BAI1 expression was related to patient survival in nonsmoking NSCLC patients. We suggest BAI1 expression as a predictive marker of nonsmoking-associated NSCLC and recommend that it be evaluated as an AJCC staging criterion in the future.

Heart failure (HF) guidelines place patients into 3 discrete groups according to left ventricular ejection fraction (LVEF) reduced (<40%), mid-range (40-49%), and preserved LVEF (≥50%). We assessed whether clinical phenogroups offer better prognostication than LVEF.

This was a sub-study of the Patient-Centered Care Transitions in HF trial. We analysed baseline characteristics of hospitalized patients in whom LVEF was recorded. We used unsupervised machine learning to identify clinical phenogroups and, thereafter, determined associations between phenogroups and outcomes. Primary outcome was the composite of all-cause death or rehospitalization at 6 and 12months. Secondary outcome was the composite cardiovascular death or HF rehospitalization at 6 and 12months. Cluster analysis of 1693 patients revealed six discrete phenogroups, each characterized by a predominant comorbidity coronary heart disease, valvular heart disease, atrial fibrillation (AF), sleep apnoea, chronic obstructive pulmonary disease (COPdentifier NCT02112227.
Although the prognostic impact of the high tricuspid regurgitation pressure gradient (TRPG) has been investigated, the association of the decrease in TRPG during follow-up with clinical outcomes in heart failure (HF) has not been previously studied. The aim of this study was to investigate the association of a decrease in TRPG between hospitalization and 6month visit with subsequent clinical outcomes in patients with acute decompensated HF (ADHF).

Among 721 patients with available TRPG data both during hospitalization and a subsequent 6month visit, the study population was divided into two groups a decrease in TRPG group (>10mmHg decrease at 6month visit) (N=179) and no decrease in TRPG group (N=542). The primary outcome measure was a composite of all-cause death or HF hospitalization. The cumulative 6month incidence of primary outcome measure was significantly lower in the decrease in TRPG group than in the no decrease in TRPG group (12.2% vs. 18.7%, P=0.02). After adjusting for confounders, there was a significantly lower risk in decrease in TRPG group than in the no decrease in TRPG group for the measured primary outcome (hazard ratio 0.56, 95% confidence interval 0.32-0.93, P=0.02). The lower risk in decrease in TRPG group was not different among the basal TRPG values.

Heart failure patients with a decrease in TRPG at 6months after discharge from ADHF hospitalization had lower subsequent risk of all-cause death and HF hospitalization than those without a decrease in TRPG, regardless of TRPG values.

To analyze the role of six human epididymis protein 4 (HE4)-related mitochondrial ribosomal proteins (MRPs) in ovarian cancer and selected MRPL15, which is most closely related to the tumorigenesis and prognosis of ovarian cancer, for further analyses.

Using STRING database and MCODE plugin in Cytoscape, six MRPs were identified among genes that are upregulated in response to HE4 overexpression in epithelial ovarian cancer cells. The Cancer Genome Atlas (TCGA) ovarian cancer, GTEX, Oncomine, and TISIDB were used to analyze the expression of the six MRPs. The prognostic impact and genetic variation of these six MRPs in ovarian cancer were evaluated using Kaplan-Meier Plotter and cBioPortal, respectively. MRPL15 was selected for immunohistochemistry and GEO verification. TCGA ovarian cancer data, gene set enrichment analysis, and Enrichr were used to explore the mechanism of MRPL15 in ovarian cancer. Finally, the relationship between MRPL15 expression and immune subtype, tumor-infiltrating lymphocytes, and immune regulatory factors was analyzed using TCGA ovarian cancer data and TISIDB.
