Severe overfeeding of critically ill patients results in increased complications without clinical benefits. However, the optimal timing and amount of nutrition to feed critically ill adults has not been established. There are multiple prediction equations for estimating calorie expenditure of critically ill patients, but most studies comparing the accuracy of different prediction equations are ...

We compared the efficacy of activity monitor (which displays exercise intensity and number of steps) versus that of pedometer in exercise therapy for patients with type 2 diabetes. The study subjects were divided into the activity monitor group (n = 92) and pedometer group (n = 95). The primary goal was improvement in hemoglobin A1c (HbA1c). The exercise target was set at 8,000 steps/day and 20...

Calorie restriction is known to extend lifespan among organisms by a debating mechanism underlying nitric oxide-driven mitochondrial biogenesis. We report here that nitric oxide generators including artemisinin, sodium nitroprusside, and L-arginine mimics calorie restriction and resembles hydrogen peroxide to initiate the nitric oxide signaling cascades and elicit the global antioxidative respo...

Calorie Restriction (CR) is a defined intervention tool currently being studied as an effort to achieve numerous health benefits and increase longevity. Currently, there is a large body of research that indicates a multitude of health benefits and positive associations; however, there is also a plethora of opposing research. Through investigation of epigenetics, the efficacy of calorie restrict...

The present study investigated the effect of taxing high-energy dense products and subsidizing low-energy dense products on changes in calorie consumption. More specifically, we hypothesized that 'more impulsive' individuals were less influenced by such pricing strategies compared to 'less impulsive' individuals. Contrary to our hypothesis, results showed that 'more impulsive' individuals adjus...

In 2008, New York City mandated that all multi-unit restaurants post calorie information in their menu. For managers of multi-unit and stand-alone restaurants, and for policy makers, a pertinent goal might be to monitor the impact of this regulation on consumer conversations. We propose a scalable Bayesian topic model to measure and understand changes in consumer opinion about health (and other...

A primary goal of nutritional support is to provide the energy requirements needed to sustain metabolic processes, maintain body temperature and tissue repair. The beginnings of artificial nutrition were characterized by high calorie nutritional formulae. The assimilation of physiological concepts, accumulating research data and clinical experience led to a progressive reduction of this intake....

The goal of this study was to measure arterial amino acid levels in patients with chronic heart failure (CHF), and relate them to left ventricular function and disease severity. Amino acids (AAs) play a crucial role for heart protein-energy metabolism. In heart failure, arterial AAs, which are the major determinant of AA uptake by the myocardium, are rarely measured. Forty-one subjects with cli...
