The prognostic nutritional index might predict clinical outcomes in patients with idiopathic dilated cardiomyopathy

The prognostic nutritional index (PNI) had been associated with adverse outcomes in numerous clinical conditions. However, its influence on idiopathic dilated cardiomyopathy (DCM) was not determined. This aim of this study was to determine the predictive ability of PNI in patients with idiopathic DCM.

(Intermountain Medical Center) Researchers from the Intermountain Healthcare Heart Institute in Salt Lake City have identified new mutations in a gene commonly associated with non-ischemic dilated cardiomyopathy (NIDC), a disease that weakens the heart muscle, making it more difficult to adequately circulate blood to meet the body's needs.

In this study, we investigated the role of miR-223-3p in experimental autoimmune myocarditis (EAM). We found that miR-223-3p expression was significantly lower in EAM mice than that in normal mice. miR-223-3p inhibited NLRP3 inflammasome expression, promoting the polarization of dendritic cells (DCs) towards a tolerogenic DC phenotype. miR-223-3p effectively induced regulatory T cell (Treg) generation by inhibiting the function of antigen-presenting DCs. Transfer of miR-223-3p-overexpressing DCs protected mice against the development of EAM. Our findings suggest that miR-223-3p is involved in the induction of the tolerogen...

This study provides a new strategy for research on DCM or other diseases. Furthermore, lncRNA-miRNA pairs may be regarded as candidate diagnostic biomarkers or potential therapeutic targets of DCM.

We investigated a dilated cardiomyopathy (DCM) mutation (F764L) in human β-cardiac myosin by determining its motor properties in the presence and absence of the heart failure drug omecamtive mecarbil (OM). The mutation is located in the converter domain, a key region of communication between the catalytic motor and lever arm in myosins, and is nearby but not directly in the OM-binding site. We expressed and purified human β-cardiac myosin subfragment 1 (M2β-S1) containing the F764L mutation, and compared it to WT with in vitro motility as well as steady-state and transient kinetics measurements. In the absen...

RASopathies are a group of rare genetic diseases caused by germline mutations in genes involved in the RAS–mitogen-activated protein kinase (RAS-MAPK) pathway. Whole-exome sequencing (WES) is a powerful approach for identifying new variants in coding and noncoding DNA sequences, including miRNAs. miRNAs are fine-tuning negative regulators of gene expression. The presence of variants in miRNAs could lead to malfunctions of regulation, resulting in diseases. Here, we identified 41 variants in mature miRNAs through WES analysis in five patients with previous clinical diagnosis of RASopathies syndromes. The pathways, bio...

In this study, we investigated the long noncoding RNA (lncRNA) and messenger RNA (mRNA) expressions in the plasma of patients with DCM and ICM and analyzed the different lncRNA profile between the two groups. The microarray analysis identified 3,222 and 1,911 significantly differentially expressed lncRNAs and mRNAs between DCM and ICM group. The most enriched upregulated functional terms included positive regulation of I-kappaB kinase/nuclear factor-kappaB signaling and regulation of cellular localization, while the top 10 downregulated genes mainly consisted of acid secretion and myosin heavy chain binding. Furthermore, t...

This study compared the myocardial deformation patterns of ICM and NICM using 2-D speckle tracking echocardiography (2-D STE) and sought to find parameters valuable in the diagnosis and management of dilated cardiomyopathy. The study population comprised 84 consecutive patients with LV end-diastolic dimension>55 mm and ejection fraction (EF)

We report a case of an 8-year-old girl who presented with syncopal attacks and a history of viral illness a month ago. On examination, she was conscious, oriented but had a heart rate of 42/min which was unresponsive to atropine. She was started on dobutamine and isoproterenol. Electrocardiography and echocardiography revealed complete heart block with moderate tricuspid regurgitation, dilated cardiomyopathy and low ejection fraction. Patient was planned for urgent permanent pacemaker insertion. General anaesthesia was administered with endotracheal tube and controlled ventilation using fentanyl, ketamine and pancuronium. ...
