Transcatheter valve-in-valve or valve-in-ring implantation with a novel balloon-expandable device in patients with bioprosthetic left side heart valves failure: 1-year follow-up from a multicenter experience.

Background: Transcatheter aortic and mitral valve-in-valve (ViV) or valve-in-ring (ViR) implantation into failed bioprosthetic heart valves (BHVs) or rings represents an appealing, less invasive, treatment option for patients at high surgical risk. Nowadays, few data have been reported on the use of balloon-expandable Myval (Meril Life Science, Vapi, India) transcatheter heart valve (THV) for the treatment of degenerated BHVs or rings. We aimed at evaluating the early and mid-term clinical outcomes of patients with left side heart bioprosthesis deterioration treated with transcatheter ViV/ViR implantation using Myval THV.

PPIA rs6850: A > G single-nucleotide polymorphism is associated with raised plasma cyclophilin A levels in patients with coronary artery disease.

Plasma level of cyclophilin A is a promising marker of vascular disease in patients with type 2 diabetes. Genetic variants in the peptidylprolyl isomerase A gene, encoding human cyclophilin may alter protein synthesis thus affecting its activity, function, and circulating plasma levels. We examined the effect of single-nucleotide polymorphisms (SNPs) within the PPIA gene on plasma levels of cyclophilin A and coupled this with status of vascular disease in patients with and without type 2 diabetes in 212 South Indian subjects.

Plasma level of cyclophilin A is increased in patients with type 2 diabetes mellitus and suggests presence of vascular disease.

Aims/hypothesis: Cyclophilin A, an immunophilin is secreted from human monocytes activated by high glucose. Given its role as an inflammatory mediator of vascular tissue damage associated with inflammation and oxidative stress, we examined plasma levels of cyclophilin A in normal healthy volunteers and patients with type 2 diabetes (DM), with or without coronary artery disease (CAD).

Methods: Study subjects comprised of 212 patients with DM and CAD,101 patients with diabetes, 122 patients with CAD and 121 normal healthy volunteers.

A 45-year old man with recurrent syncope: an unusual presentation of coronary artery disease.

A 45-year old normotensive, euglycaemic, non-smoker was referred from a peripheral hospital to the Cardiology unit of the University College Hospital, Nigeria for evaluation of recurrent exercise induced syncope. Initial 12-lead electrocardiogram (ECG), 24-hr ambulatory ECG, trans-thoracic echocardiogram and electroencephalogram (EEG) were normal. A repeat episode of syncope warranted further investigation.

Proteomic profiling of high glucose primed monocytes identifies cyclophilin A as a potential secretory marker of inflammation in type 2 diabetes.

Hyperglycemia is widely recognized to be a potent stimulator of monocyte activity, which is a crucial event in the pathogenesis of atherosclerosis. We analyzed the monocyte proteome for potential markers that would enhance the ability to screen for early inflammatory status in Type 2 diabetes mellitus (T2DM), using proteomic technologies. Monocytic cells (THP-1) were primed with high glucose (HG), their protein profiles were analyzed using 2DE and the downregulated differentially expressed spots were identified using MALDI TOF/MS.
