Aims: Mutations in PRKAG2, the gene encoding for the γ2 subunit of 5'-AMP-activated protein kinase (AMPK), are responsible for an autosomal dominant glycogenosis with a cardiac presentation, associating hypertrophic cardiomyopathy (HCM), ventricular pre-excitation (VPE), and progressive heart block. The aim of this study was to perform a retrospective time-to-event study of the clinical manifestations associated with PRKAG2 mutations. Methods and Results: A cohort of 34 patients from 9 families was recruited between 2001 and 2010...

Obstructive sleep apnoea (OSA) affects 9-24% of the adult population. OSA is associated with atrial disease, including atrial enlargement, fibrosis and arrhythmias. Despite the link between OSA and cardiac disease, the molecular changes in the heart which occur with OSA remain elusive. To study OSA-induced cardiac changes, we utilized a recently developed rat model which closely recapitulates the characteristics of OSA. Male Sprague Dawley rats, aged 50-70 days, received surgically implanted tracheal balloons which were inflated to cause transient airway obstructions...

INTRODUCTION: In 2014, the incidence of prostate cancer in the Russian Federation was 116.4 per 100,000 population. It is noteworthy that from 2004 to 2014, the proportion of patients with stage I-II prostate cancer increased from 35.5% to 52.5%, while that of patients with stages III and IV disease decreased from 38.4% to 29% and from 22.7% to 16.5%, respectively. All of this allows an increasing number of prostate cancer patients to be treated with radical treatment - low dose-rate brachytherapy...

Elderly people represent the fastest growing portion of cardiovascular patients. We aimed to analyze the clinical presentation, risk factors, co-morbidities, complications, and mortality in patients 90 years or more who underwent coronary angiography and intervention.We retrospectively studied 108 (0.25% of 43,385) consecutive patients ≥ 90 years undergoing cardiac catheterization and/or intervention in a tertiary specialist hospital between 2003 and 2014.Most patients (68.5%) were introduced on an emergency basis, especially with acute coronary syndrome (ACS) (63...

Vascular complications (VC) following transcatheter aortic valve replacement (TAVR) are associated with worse outcomes. The trend of VC incidence in patients considered high risk is unclear. We sought to assess the trend of VC after TAVR in patients at high risk. We investigated the VC trend in female, diabetes mellitus, and peripheral vascular disease (PVD) patients. Patients who underwent TAVR from 2011 to 2014 in the United States were identified using the International Classification of Diseases-Ninth Revision code 35...

BACKGROUND: Coronary artery disease (CAD) is common in asymptomatic chronic dialysis patients and plays an important role in their poor survival. Early identification of these high-risk patients could improve treatment and reduce mortality. Abdominal aortic calcification (AAC) has previously been associated with CAD in autopsy studies. Since the AAC can be quantified easily using a lateral lumbar X-ray we hypothesized that the extent of AAC as assessed on a lateral lumbar X-ray might be predictive of the presence of significant CAD in dialysis patients...

A 67-year-old man was admitted to our hospital after episodes of syncope preceded by malaise and diffuse neck and chest discomfort. No family history of cardiac disease was reported. Laboratory workup was within normal limits, including D-dimers, serum troponin I and arterial blood gases. The electrocardiogram showed sinus rhythm with T-wave inversion in leads V1 to V3. Computed tomography angiography to investigate pulmonary embolism showed no abnormal findings. Transthoracic echocardiography (TTE) displayed massive enlargement of the right ventricle with intact interatrial septum and no pulmonary hypertension...

Severe tricuspid regurgitation (TR) remains a vastly undertreated disease, with sustained elevation of right atrial (RA) pressure directly resulting in chronic end-organ damage. Recently, bi-caval valve implantation has been shown to improve symptoms in patients with symptomatic TR who are at high risk for surgery. We present the first report of intermediate term hemodynamic effects of single inferior vena cava (IVC) valve implantation (CAVI) for treatment of severe TR. We performed CAVI on a 66-year-old female with severe TR, who suffered from repeat hospitalizations for treatment refractory NYHA class III-IV heart failure symptoms and had prohibitive operative risk...

Implantable cardioverter defibrillators (ICD) and cardiac resynchronization therapy (CRT) reduce mortality in many patients with heart failure (HF), but the current use and effectiveness of ICD/CRT in patients with chronic kidney disease (CKD) are uncertain. We examined associations between kidney function and guideline-recommended prescription of ICD/CRT in the Get With The Guidelines-Heart Failure registry, a performance improvement program for hospitalized patients with HF. We compared differences in ICD and CRT prescription between the following categories of estimated glomerular filtration rate (eGFR; mL/min/1...

BACKGROUND: Although aortic stiffness assessed by pulse wave velocity (PWV) is a strong predictor of coronary artery disease, the significance of local coronary stiffness has never been tackled. The first objective of this study was to describe a method of measuring coronary PWV (CoPWV) invasively and to describe its determinants. The second objective was to assess both CoPWV and aortic PWV in patients presenting with acute coronary syndromes or stable coronary artery disease. METHODS AND RESULTS: In 53 patients, CoPWV was measured from the delay in pressure wave and distance traveled as a pressure wire was withdrawn from the distal to the proximal coronary segment...

OBJECTIVE Adjacent-level disc degeneration following cervical fusion has been well reported. This condition poses a major treatment dilemma when it becomes symptomatic. The potential application of cervical arthroplasty to preserve motion in the affected segment is not well documented, with few studies in the literature. The authors present their initial experience of analyzing clinical and radiological results in such patients who were treated with arthroplasty for new or persistent arm and/or neck symptoms related to neural compression due to adjacent-segment disease after anterior cervical discectomy and fusion (ACDF)...

PURPOSE: Optimal curative intent brachytherapy for certain gynecologic cancers requires interstitial brachytherapy, often using template-guided techniques such as a Syed-Neblett implant. Whether high or low dose rate (LDR), these procedures pose significant risks to patients, partly attributable to the prolonged period of bed rest. Published results of free-handed permanent interstitial brachytherapy (PIB) with (131)Cs demonstrate it to be an effective modality for the management of small volume gynecologic cancers...

Mechanical load influences bone structure and mass. Arguing the importance of load-transduction, we investigated the mechanisms inducing bone formation using an elastomeric substrate. We characterized Poly (glycerol sebacate) (PGS) in-vitro for its mechanical properties, compatibility with osteoprogenitor cells regarding adhesion, proliferation, differentiation under compression versus static cultures and in-vivo for the regeneration of a rabbit ulna critical size defect. The load-transducing properties of PGS were compared in-vitro to a stiffer poly lactic-co- glycolic-acid (PLA/PGA) scaffold of similar porosity and interconnectivity...

Transplantation of fetal ventral mesencephalic (VM) neurons for Parkinson's disease (PD) is limited by poor survival and suboptimal integration of grafted tissue into the host brain. In a 6-OHDA rat model of PD we investigated the feasibility of simultaneous transplantation of rat fetal VM tissue and polymer-encapsulated C2C12 myoblasts genetically modified to produce glial cell line-derived neurotrophic factor or mocktransfected myoblasts on graft function. Amphetamine-induced rotations were assessed prior and 2, 4, 6 and 9 weeks post-transplantation...

Bioresorbable scaffolds have the potential to overcome several problems associated with metallic stents. Bioresorbable poly-L-lactic acid (PLLA) scaffold implantation for the treatment of peripheral artery disease has already been reported in animal models and clinical trials; however, no studies comparing PLLA scaffolds and bare metal stents (BMSs) with regard to early vascular morphological changes, identified using intravascular ultrasound (IVUS) analysis, have been reported. In this study, PLLA scaffolds and BMSs were implanted bilaterally in iliac arteries of five miniature pigs...
