Renal Denervation, Blood Pressure and Metabolic Disease: Not a Simple Solution

Cathryn M. Kolka

Article Type: Commentary | First Published: September 01, 2015

Diabetes, obesity, cardiovascular disease and hypertension are frequently grouped together as the 'metabolic syndrome'. The prevalence of these diseases is increasing in the United States and worldwide. In recent years, overactivity of the sympathetic nervous system has been linked to obesity, hypertension, and cardiovascular disease. Promising initial research investigated the role of the sympathetic nervous system in hypertension: renal denervation using catheter-based radiofrequency ablation ...

Serum Endothelin-1 Elevation in Diabetes. A Reflection of Pathophysiological Process or a Biomarker beyond Expectation?

Article Type: Editorial | First Published: August 21, 2015

Endothelin or endothelium-derived constricting factor was first discovered by O'Brien et al. in 1987 as a potent vasoconstrictor protein from culture medium of bovine aortic and pulmonary endothelium. The culture medium was shown to cause aortic ring constriction in vitro and vasoconstriction when perfused into rabbit coronary arteries. Concomitantly, Yanagisawa et al. isolated and sequenced the 21 amino acid endothelin, which modulates voltage dependent channel and is a potent vasoconstrictor p...

Article Type: Research Article | First Published: August 15, 2015

Aim: To identify the risk of falling through a functional mobility test in non-diabetics, individuals with diabetic neuropathy and individuals with diabetic neuropathy and vasculopathy. Methodology: The study was composed of 61 subjects of both genders divided into the control group CG (n=32), diabetic neuropathy group DNG (n=18) and diabetic neuropathy-vasculopathy group (DNVG) (12). The participants underwent initial an evaluation through somatosensory sensitivity tests, diagnosis of polyneuro...

Exergaming to Improve Physical and Mental Fitness in Children and Adolescents with Autism Spectrum Disorders: Pilot Study

Claudia L. Hilton, Allison Attal, John Best, Tim Reistetter, Pete Trapani and Diane M. Collins

Article Type: Research Article | First Published: August 18, 2015

Although not included as core characteristics of autism spectrum disorders (ASD), children and adolescents with this diagnosis often experience executive function (EF) and motor impairments. This study investigated the use of a speed-based exergame called the Makoto arena as an intervention strategy to improve EF and motor performance in in 17 school-aged children and adolescents with ASD. All areas of EF improved, with significance in the overall global executive composite and in the metacognit...

Effects of Pitching a Simulated Game on Upper Extremity Kinematics in Youth Baseball Pitchers

Gretchen D. Oliver and Hillary A. Plummer

Article Type: Original Research Article | First Published: August 09, 2015

Overuse injuries in youth baseball players have increased exponentially with the insurgence of participation in the sport. It has been estimated that 5 million children (6-17 years) participate in organized youth baseball in the United States. Additionally, it has been documented in a survey of 476 youth pitchers (9-14 years) that roughly half reported either shoulder or elbow pain while pitching, thus leading researchers to speculate overuse injury. As overuse injuries are continuing to be appa...

Dynamic Factor Analysis for Multivariate Time Series: An Application to Cognitive Trajectories

Yorghos Tripodis and Nikolaos Zirogiannis

Article Type: Research Article | First Published: August 28, 2015

We propose a dynamic factor model appropriate for large epidemiological studies and develop an estimation algorithm which can handle datasets with large number of subjects and short temporal information. The algorithm uses a two cycle iterative approach for parameter estimation in such a large dataset. Each iteration consists of two distinct cycles, both following an EM algorithm approach. This iterative process will continue until convergence is achieved. We utilized a dataset from the National...

Randomized Trial of a Discharge Planning and Telehealth Intervention for Patients Aged 65 and older after Coronary Artery Bypass Surgery

Ruth M. Kleinpell, Boaz Avitall, Cathy Catrambone, Tricia Johnson, Louis Fogg, Shirley Moore and Nicole T. Thompson

Article Type: Research Article | First Published: August 28, 2015

Despite diagnostic and treatment advances, coronary heart disease (CHD) remains the leading cause of death in Americans over the age of 65. Coronary artery bypass surgery (CABG) is the most frequently performed major surgery for CHD in the United States (U.S.). While the rates of CABG surgeries have declined in recent years due to the increased use of percutaneous coronary procedures, current treatment guidelines from the American Heart Association and the American College of Cardiology identify...

Hemolytic Anemia 19 Years after Mitral Valve Replacement with A Porcine Bioprosthesis

Debora Corsi, Michele Celiento, Stefano Pratali, Alberto Balbarini and Uberto Bortolotti

Article Type: Case Report | First Published: August 27, 2015

A 58-year-old man had undergone mitral valve replacement with a 27 mm Carpentier-Edwards porcine bioprosthesis (Edwards Lifesciences, Irvine, USA) in 1993. Nineteen years later he presented with dark urine, fatigue and moderate dyspnea denying any history of infection. He was in atrial fibrillation with a systolic mitral regurgitant murmur. Hematologic evaluation was consistent with haemolytic anemia; particularly, reduced hemoglobin, hematocrit and haptoglobin (6.6 mg/dl), and increased total b...

Traumatic Bilateral Renal Artery Thrombosis: A Case of Kidney Salvage with Local Lytic Therapy and Systemic Anticoagulation in the Setting of Poly-trauma

Allan Capote, Martin Goldman, Kevin Kemp and Ruby Skinner

Article Type: Case Report | First Published: August 28, 2015

With the advent of advances in endovascular techniques and interventional radiology, the treating physician has added very useful and relatively less invasive methods of managing otherwise complex traumatic injuries compared to open surgical techniques. One such application is in the treatment of acute traumatic solid organ injuries, and some of the earliest applications related to the management of blunt spleen and liver injuries. Acute traumatic renal artery occlusion is a rare pattern of kidn...

Vancomycin Hypersensitivity Reaction Presenting with Extensive Oral Ulcerations

Justin G. Hastings, Alok Vij and Anthony P. Fernandez

Article Type: Case Report | First Published: August 15, 2015

Vancomycin therapy is associated with several hypersensitivity reactions, the most common being the non-immunologically mediated 'red man syndrome'. Fever, rash, neutropenia, and other manifestations have also been variably associated with a vancomycin hypersensitivity reaction that is likely immunologically mediated. Here we report a 45-year old man who developed diffuse oral aphthous-like ulcers as the most prominent manifestation of vancomycin hypersensitivity reaction. We identified only two...
