    Background and Objectives: Studies show that inflammation can contribute to an increase in resting energy expenditure in patients with chronic kidney disease; however, findings about total energy expenditure (TEE) have not been reported. The aim of this study was to evaluate the effects of inflammation on TEE and physical activity energy expenditure in hemodialysis (HD) patients.Design: This was a cross-sectional study.Setting: This study was conducted from Hopital Edouard Herriot, Lyon, France.Patients: This study included 24 HD patients and 18 healthy subjects.Main Outcome Measure: TEE and step counts were measured over a 7-day period by the SenseWear Pro2 Armband in 24 HD patients (15 patients with C-reactive protein,5 mg/L, aged 67.0 +/- 6 14.7 years, and 9 with C-reactive protein >5 mg/L, aged 69.0 +/- 6 18.0 years) and compared with 18 healthy subjects (62.3 +/- 6 15.3 years).Results: Mean estimated TEE measured with SenseWear Pro2 Armband was significantly lower (25.5 +/- 4.1 kcal/kg/day) in patients with inflammation when compared with those without inflammation (32.0 +/- 6.7 kcal/kg/day) and with healthy subjects (31.8 +/- 6 7.0 kcal/kg/day) (P = .012). There was a difference in the physical activity (step counts) between patient groups (P < .05). Healthy subjects and patients without inflammation walked more (8,107 +/- 5,419 and 6,016 +/- 3,752 steps/day, respectively) as compared with patients with inflammation (2,801 +/- 2,754 steps/day, P = .001).Conclusion: Our findings suggest that patients with inflammation have a lower TEE when compared with healthy subjects and patients without inflammation. TEE is influenced by physical activity because patients with inflammation appear to be less active. (C) 2011 by the National Kidney Foundation, Inc. All rights reserved

    The accurate estimation of total daily energy expenditure (TEE) in chronic kidney patients is essential to allow the provision of nutritional requirements; however, it remains a challenge to collect actual physical activity and resting energy expenditure in maintenance dialysis patients. The direct measurement of TEE by direct calorimetry or doubly labeled water cannot be used easily so that, in clinical practice, TEE is usually estimated from resting energy expenditure and physical activity. Prediction equations may also be used to estimate resting energy expenditure; however, their use has been poorly documented in dialysis patients. Recently, a new system called SenseWear Armband (BodyMedia, Pittsburgh, PA) was developed to assess TEE, but so far no data have been published in chronic kidney disease patients. The aim of this review is to describe new measurements of energy expenditure and physical activity in chronic kidney disease patients

    AIM: Real-life analysis of overall survival (OS) trends among metastatic breast cancer (MBC) patients may help define medical needs and evaluate the impact of public health investments. The present study aimed to evaluate the independent impact of the year of MBC diagnosis on OS in the Epidemio-Strategy-Medical-Economical (ESME)-MBC cohort. METHODS: ESME-MBC (NCT03275311) is a French, national, multicentre, observational cohort including 16,702 consecutive newly diagnosed MBC patients (01 January 2008-31 December 2014). Of 16,680 eligible patients, 15,085 had full immunohistochemistry data, allowing classification as hormone receptor-positive and HER2-negative (HR+/HER2-, N = 9907), HER2-positive (HER2+, N = 2861) or triple-negative (HR-/HER2-, N = 2317) subcohorts. Multivariate analyses of OS were conducted among the full ESME cohort and subcohorts. RESULTS: Median OS of the whole cohort was 37.22 months (95% confidence interval [CI], 36.3-38.04). Year of diagnosis was an independent predictor of OS (hazard ratio 0.98 [95% CI, 0.97-1.00], P = .01) together with age, subtype, disease-free interval, visceral metastases and number of organs involved. Median OS of HR+/HER2-, HER2+ and HR-/HER2- subcohorts was, respectively, 42.12 (95% CI, 40.90-43.10), 44.91 (95% CI, 42.51-47.90) and 14.52 (95% CI, 13.70-15.24) months. Year of diagnosis was a strong independent predictor of OS in HER2+ subcohort (hazard ratio 0.91 [95% CI, 0.88-0.94], P < .001), but not in HR+/HER2- nor HR-/HER2- subcohorts (hazard ratio 1.00 [95% CI, 0.98-1.01], P = .80 and 1.00 [95% CI, 0.97-1.02], P = .90, respectively). CONCLUSIONS: The OS of MBC patients has slightly improved over the past decade. However, this effect is confined to HER2+ cases, highlighting the need of new strategies in the other subtypes
