OBJECTIVES The purpose of this study was to determine whether the response to ventricular pacing during tachycardia is useful for differentiating atypical atrioventricular node re-entrant tachycardia (AVNRT) from orthodromic reciprocating tachycardia (ORT) using a septal accessory pathway. BACKGROUND Although it is usually possible to differentiate atypical AVNRT from ORT using a septal acces...

The impact of oral rehydration therapy (ORT) on the recent decline in diarrhoea mortality in the northeast of Brazil was studied. Proportionate infant mortality fell from 32% in 1980 to 17% in 1989 and infant deaths attributed to diarrhoea dropped from 41% to 25%, resulting in an overall reduction of 57%. Similar decreases were observed for children aged 1-4 years. Diarrhoea admissions also fel...

Two sources of workers’pro-social motivation have been considered in the literature: actionoriented altruism and output-oriented altruism. This paper presents evidence from a …eld experiment, which aims to identify and quantify them. The idea behind our experimental design is to measure in a precise way the level of e¤ort exerted in an environment that elicits purely sel…sh behavior and compare...

PURPOSE To compare optical coherence tomography (OCT) and histology of outer retinal tubulation (ORT) secondary to advanced age-related macular degeneration in patients and in postmortem specimens, with particular attention to the basis of the hyperreflective border of ORT. METHOD A private referral practice (imaging) and an academic research laboratory (histology) collaborated on two retrosp...

OBJECTIVE This article reviews and synthesizes evidence in the published literature on the safety and efficacy of oral rehydration therapy (ORT) among young children with pediatric gastroenteritis in developed nations. METHODOLOGY We searched the literature for randomized, controlled trials comparing the safety and efficacy of ORT with intravenous (IV) rehydration treatment and/or oral rehydr...

BACKGROUND Fibroblast growth factor-2 (FGF-2) protein level has been shown to be elevated in aged mice muscle compared to adult mice. It activates the satellite cell quiescence, which leads to satellite cell depletion and may accelerate aging process. The purpose of this study was to see the effect of resistance exercise on skeletal muscle FGF-2 protein level in aged mice. METHODS This study ...

OBJECTIVE To provide clinicians with a brief screening tool to predict accurately which individuals may develop aberrant behaviors when prescribed opioids for chronic pain. DESIGN One hundred and eighty-five consecutive new patients treated in one pain clinic took the self-administered Opioid Risk Tool (ORT). The ORT measured the following risk factors associated in scientific literature with...

Objective: To compare perioperative outcomes of robotic-assisted (RALS) versus conventional laparoscopic surgery (CLS) in endometrial cancer. Methods: This is a retrospective analysis of a prospectively maintained database of procedures performed from January 2009 to January 2014 by a single surgeon experienced in both minimally invasive techniques. One hundred and five patients underwent surgi...

In neuroimaging studies of human cognitive abilities, brain activation patterns that include regions that are strongly interactive in response to experimental task demands are of particular interest. Among the existing network analyses, partial least squares (PLS; McIntosh, 1999; McIntosh, Bookstein, Haxby, & Grady, 1996) has been highly successful, particularly in identifying group differences...

In 1980, diarrhoea was the leading cause of child mortality, accounting for 4.6 million deaths annually. Efforts to control diarrhoea over the past decade have been based on multiple, potentially powerful interventions implemented more or less simultaneously. Oral rehydration therapy (ORT) was introduced in 1979 and rapidly became the cornerstone of programmes for the control of diarrhoeal dise...
