Safety and efficacy of coffee enriched with inulin and dextrin on satiety and hunger in normal volunteers.

Objectives: This study assessed the safety and efficacy of a new beverage on suppressing hunger and improving feelings of satiety in healthy volunteers.

Methods: In the safety study, participants (n = 269) received either 1) a control beverage-coffee alone (group C); 2) the study beverage-coffee, whey protein, inulin, and dextrin (group S); or 3) an inulin-enriched beverage (I group). The study was held over a 7-d period during which participants were required to consume 2 cups of coffee a day.

Preemptive enteral nutrition enriched with eicosapentaenoic acid, gamma-linolenic acid and antioxidants in severe multiple trauma: a prospective, randomized, double-blind study.

Background: Severe injury triggers a complex systemic immune response which may result in significant respiratory compromise, including the development of acute respiratory distress syndrome (ARDS). No randomized clinical trial has assessed the role of nutritional interventions to limit respiratory complications.

Methods: This was a single-center, prospective, randomized, comparative, double-blind, controlled study of patients with severe trauma requiring mechanical ventilation.

Comparison between two metabolic monitors in the measurement of resting energy expenditure and oxygen consumption in diabetic and non-diabetic ambulatory and hospitalized patients.

Objective: The aim of this study was to assess the validity and reliability of the Fitmate metabolic system in measuring the oxygen consumption and resting metabolic rate (RMR) in ambulatory and hospitalized patients.

Methods: We conducted a prospective simultaneous clinical comparison. We enrolled 37 patients (19 women and 18 men) for the four groups of the study.

Computerized lung acoustic monitoring can help to differentiate between various chest radiographic densities in critically ill patients.

Background: Complementary bedside lung monitoring modalities are often sought in order to assist in the differentiation between several lung opacities in the intensive care unit (ICU).

Objectives: To evaluate the use of computerized lung acoustic monitoring as a complementary approach in the differentiation between various chest radiographic densities in critically ill patients.

Methods: Lung vibration intensity was assessed in 82 intensive care patients using vibration response imaging.

Changes in regional distribution of lung sounds as a function of positive end-expiratory pressure.

Introduction: Automated mapping of lung sound distribution is a novel area of interest currently investigated in mechanically ventilated, critically ill patients. The objective of the present study was to assess changes in thoracic sound distribution resulting from changes in positive end-expiratory pressure (PEEP). Repeatability of automated lung sound measurements was also evaluated.
