Several factors may alter apparent resting metabolic rate (RMR) during measurement with indirect calorimetry. Likewise, numerous indirect calorimetry measurement protocols have been developed over the years, and the methodology employed could influence test results. As part of a larger project to determine the role of indirect calorimetry in clinical(More)
BACKGROUND An assessment of energy needs is a necessary component in the development and evaluation of a nutrition care plan. The metabolic rate can be measured or estimated by equations, but estimation is by far the more common method. However, predictive equations might generate errors large enough to impact outcome. Therefore, a systematic review of the(More)
Abnormal composition of intestinal bacteria--"dysbiosis"-is characteristic of Crohn's disease. Disease treatments include dietary changes and immunosuppressive anti-TNFα antibodies as well as ancillary antibiotic therapy, but their effects on microbiota composition are undetermined. Using shotgun metagenomic sequencing, we analyzed fecal samples from a(More)
Nutrition screening, assessment, and intervention in patients with malnutrition are key components of nutrition care (Figure 1). Nutrition screening has been defined by the American Society for Parenteral and Enteral Nutrition (A.S.P.E.N.) as “a process to identify an individual who is malnourished or who is at risk for malnutrition to determine if a(More)
BACKGROUND A lack of agreement on definitions and terminology used for nutrition-related concepts and procedures limits the development of clinical nutrition practice and research. OBJECTIVE This initiative aimed to reach a consensus for terminology for core nutritional concepts and procedures. METHODS The European Society of Clinical Nutrition and(More)
OBJECTIVE The consumption of an agrarian diet is associated with a reduced risk for many diseases associated with a 'Westernised' lifestyle. Studies suggest that diet affects the gut microbiota, which subsequently influences the metabolome, thereby connecting diet, microbiota and health. However, the degree to which diet influences the composition of the(More)
OBJECTIVE Optimal intake of energy and protein is associated with improved outcomes, although outcomes relative to protein intake are very limited. Our purpose was to evaluate the impact of prescribed protein delivery on mortality and time to discharge alive (TDA) using data from the International Nutrition Survey 2013. We hypothesized that greater protein(More)
OBJECTIVE The purpose of this study was to examine two separate socioeconomic status (SES) indicators of obesity in Botswana, an African country that has experienced rapid economic development and where the prevalence of human immunodeficiency virus/acquired immune deficiency syndrome is high. METHODS We conducted a nationally representative,(More)
INTRODUCTION The purpose of this study was to examine linkages between obesity, physical activity, and body image dissatisfaction, with consideration of socioeconomic status (SES) and urbanization in adolescents in Botswana. MATERIALS AND METHODS A nationally representative, cross-sectional survey in 707 secondary school students included measured height(More)
