Matthew S Lazarus, Rebecca B Forman, Alan L Brook, Todd S Miller
BACKGROUND: Image guidance for spine pain control procedures, including epidural steroid injection, nerve root block, and facet block, can be performed with either computed tomography (CT) or conventional fluoroscopy. CT has the advantage of improved anatomic localization and use of air for contrast; however, there are concerns that CT leads to higher radiation dose and longer procedure time. OBJECTIVE: To evaluate procedure time and radiation dose for multiple types of spine pain control procedures performed under CT guidance...

Pavle Mikulic, Nikola Bralic
This case study reports the results of a 12-year (2005-2016) follow-up study of two Olympic champion rowers. The rowers were prospective athletes at the junior level when the study began, and we monitored their relevant physiological and performance data annually. Our findings indicated that their V̇O2max gradually increased up to about 22 years of age and leveled off at a value of approximately 7 l·min(-1) with minimal fluctuations thereafter. However, the variables that directly influence the V̇O2max changed...

In a 1986 article (Am J Epidemiol. 1986;124(6):903-915), Keys et al. described and discussed 15-year findings from 15 cohorts of the Seven Countries Study (SCS), the first systematic study of diet, risk characteristics, disease-specific death rates, and their ecologic and individual associations both among and within whole populations of working men in regions with contrasting traditional diets. The SCS findings included 30-fold cohort differences in rates of death from coronary heart disease and 3-fold differences in rates of death from all causes, along with strong ecologic associations among diet, risk factors, and disease rates...

Safety pharmacology studies in dogs often integrate behavioral assessments made using video recording with physiologicmeasurements collected by telemetry. However, whether merely wearing the telemetry vest affects canine behavior and otherparameters has not been evaluated. This pilot study assessed the effect of a telemetry vest on behavioral and physiologic responses to an environmental stressor, the sounds of a thunderstorm, in Labrador retrievers. Dogs were assigned to one of 2 experimental groups (Vest and No-Vest, n = 8 dogs per group) by using a matched pairs design, with a previously determined,sound-associated anxiety score as the blocking variable...

Candidates for the subcutaneous implantable cardioverter-defibrillator (S-ICD) are screened using an electrocardiogram (S-ECG) tool to measure appropriate detection. We sought to define the S-ICD candidacy of congenital heart disease patients using the S-ECG tool. We also analyzed the reliability of the (S-ECG) tool between measurers in this population. Patients above the age of 12 and with a diagnosis associated with either a higher incidence of cardiac arrest or vascular access challenges were asked to undergo screening...

BACKGROUND: Asthma is the most common obstructive airway disease in children and adults. Nasal high flow (NHF) is a recent device that is now used as a primary support for respiratory distress. Several studies have reported use of NHF as a respiratory support in status asthmaticus; however, there are no data to recommend such practice. We therefore conducted this preliminary study to evaluate NHF therapy for children with status asthmaticus admitted to our PICU in order to prepare a multicentre randomized controlled study...

Cardiac neuronal nitric oxide synthase (nNOS) is an important molecule that regulates intracellular Ca(2+) homeostasis and contractility of healthy and diseased hearts. Here, we examined the effects of nNOS on fatty acid (FA) regulation of left ventricular (LV) myocyte contraction in sham and angiotensin II (Ang II)-induced hypertensive (HTN) rats. Our results showed that palmitic acid (PA, 100 μM) increased the amplitudes of sarcomere shortening and intracellular ATP in sham but not in HTN despite oxygen consumption rate (OCR) was increased by PA in both groups...

Medication adherence in patients with chronic heart failure is recognized as one of the major issues in the management of this pathology. Demographic status and socioeconomic conditions in African countries may have an impact on chronic heart failure treatment adherence. We conducted a cross-sectional study of patients with heart failure treated in the center of heart failure in the Department of Cardiology at the IBN ROCHD University Hospital (Morocco) from September 2014 to January 2015. The extent of medication adherence was based on a questionary: CARDIA-Questionary...

In the last years, many clinical studies have revealed that some cisplatin-treated cancer survivors have a significantly increased risk of cardiovascular events, being cisplatin-induced cardiovascular toxicity an increasing concern. The aim of the present work was to evaluate the cardiovascular alterations induced by different chronic cisplatin treatments, and to identify some of the mechanisms involved. Direct blood pressure, basal cardiac (left ventricle and coronary arteries) and vascular (aortic and mesenteric) functions were evaluated in chronic (5 weeks) saline- or cisplatin-treated male Wistar rats...

Introduction: Ventricular arrhythmia is a major cause of sudden cardiac death in patients with chronic heart failure (CHF). Our recent study demonstrates that N-type Ca(2+) currents in intracardiac ganglionic neurons are reduced in the late stage of CHF rats. Rat intracardiac ganglia are divided into the atrioventricular ganglion (AVG) and sinoatrial ganglion. Only AVG nerve terminals innervate the ventricular myocardium. In this study, we tested the correlation of electrical remodeling in AVG neurons with ventricular arrhythmogenesis in CHF rats...
