The consequences of sudden fluid shifts on body composition in critically ill patients.

Introduction: Estimation of body composition as fat-free mass (FFM) is subjected to many variations caused by injury and stress conditions in the intensive care unit (ICU). Body cell mass (BCM), the metabolically active part of FFM, is reported to be more specifically correlated to changes in nutritional status. Bedside estimation of BCM could help to provide more valuable markers of nutritional status and may promote understanding of metabolic consequences of energy deficit in the ICU patients.

What is the link between poor ultrafiltration and increased mortality in anuric patients on automated peritoneal dialysis? Analysis of data from EAPOS.

Background: Primary analysis of the European Automated Peritoneal Dialysis Outcomes Study (EAPOS) found that patients with daily ultrafiltration (UF) below a predefined target of 750 mL at baseline experienced increased mortality and continuing low UF over 2 years.

Setting: Multicenter, prospective observational study of prevalent, functionally anuric patients on automated peritoneal dialysis (APD) treated to predefined standards.

Methods: Secondary data analysis to determine clinical covariates that might support a link between poor UF and outcome, including pattern of comorbidity, prescription, nutrition as determined by Subjective Global Assessment (SGA), membrane function, and blood pressure (BP).

Do health causal attributions and coping strategies act as moderators of quality of life in peritoneal dialysis patients?

Objective: The present study aimed at testing the relationships between health causal attribution and coping mechanisms with quality of life (QOL) in patients who have end-stage renal disease (ESRD) undergoing a peritoneal dialysis (PD) treatment. It was hypothesized that QOL should be negatively associated with the severity of the disease. Problem-focused coping, internal health-related locus of control (HRLOC) and medical power HRLOC were hypothesized as positive moderators preserving a better QOL, after controlling for the severity of the disease.
