The effect of high-volume online haemodiafiltration on nutritional status and body composition: the ProtEin Stores prEservaTion (PESET) study
2018
Background Compared with conventional haemodialysis (HD), online haemodiafiltration (OL-HDF) achieves a more efficient removal of uraemic toxins and reduces inflammation, which could favourably affect nutritional status. We evaluate the effect of OL-HDF on body composition and nutritional status in prevalent high-flux HD (HF-HD) patients. Methods In all, 33 adults with chronic kidney disease (CKD) Stage 5 undergoing maintenance HF-HD were assigned to post-dilution OL-HDF (n = 17) or to remain on HF-HD (n = 16, control group) for 12 months. The primary outcome was the change in lean tissue mass (LTM), intracellular water (ICW) and body cell mass (BCM) assessed by multifrequency bioimpedance …
Nutritional predictors of cognitive impairment severity in demented elderly patients: The key role of BMI
2012
Introduction: The body mass index (BMI) is commonly used to assess nutritional status and the Mini Mental State Examination (MMSE) is a validated tool for assessing cognitive status in elderly people. Nutritional and cognitive aspects are closely related in dementia. Objectives: To establish whether BMI predicts cognitive decline in demented patients and whether an "alarm" BMI cut-off exists for declining MMSE scores. Subjects and methods: 82 elderly demented patients underwent clinical, bio-chemical and functional assessment. Design: Transversal study. Results: The mean BMI was 26.08±4.48 kg/m 2 and the mean MMSE 18.68±5.38. Patients with BMI>25 kg/m2 had significantly lower MMSE scores…
Effect of weight loss on mortality in overweight and obese nursing home residents during a 5-year follow-up.
2015
Background/Objectives:The objective of this study was to ascertain the effect of weight loss over the course of 1 year on 5-year mortality in old nursing home (NH) residents in different classes of body mass index (BMI).Subjects/Methods:A longitudinal study was conducted on 161 NH residents aged ≥70 years at the Istituto di Riposo per Anziani, Padova, Italy. Data were collected using a comprehensive geriatric assessment at baseline and at a 1-year follow-up visit. Mortality was recorded over a 5-year follow-up. We divided our sample into four groups using as cutoffs a BMI of 25 and a weight gain or loss of 5% at 1 year (BMI ≥25 and weight stable/gain, BMI ≥25 and weight loss, BMI<25 and …
Vitamin D, parathyroid hormone, and bone mass in adolescents.
2005
This article provides a review of the evidence identifying the factors related to vitamin D status in adolescents. The prevalence of vitamin D deficiency based on 25-hydroxyvitamin D [25(OH)D] of <25 nmol/L ranges from 0 to 32% depending on the season measured and the latitude of the population assessed. The factors that have been reported to affect serum 25(OH)D in adolescents include ethnicity, gender, puberty stage, parathyroid hormone (PTH), dietary vitamin D intake, and sun exposure. Vitamin D supplementation studies are limited to small populations and with supplementation focused on winter months when sunlight may be inadequate. The effects of vitamin D status and supplementation on …
Bone status assessed by quantitative ultrasound in children with inflammatory bowel disease: a comparison with DXA
2016
Background: To determine the bone status in children with inflammatory bowel diseases (IBD) using quantitative ultrasound (QUS) measurement at hand phalanges and compare the obtained results with dual-energy X-ray absorptiometry (DXA). Methods: Fifty-one children with IBD underwent DXA and QUS measurements at hand phalanges in the year 2013. The control group for the QUS consisted of 460 children. Reference data for DXA comes from Hologic Explorer. Results: QUS measurements did not differ significantly between IBD patients and healthy controls. There was no difference between UC and CD subjects. DXA measurements in patients with IBD were lower than in the healthy population. Tanner stage an…
Association between a healthy lifestyle and general obesity and abdominal obesity in an elderly population at high cardiovascular risk.
2011
DOI: 10.1016/j.ypmed.2011.06.008 https://www-sciencedirect-com.sabidi.urv.cat/science/article/pii/S0091743511002349?via%3Dihub Filiació URV: SI BACKGROUND: Diet, smoking and physical activity are important modifiable lifestyle factors that can influence body weight and fat accumulation. We assessed the relationship between lifestyle and obesity risk in a baseline analysis of the PREDIMED study, a randomized dietary primary prevention trial conducted in Spain. METHODS: 7000 subjects at high cardiovascular risk were assessed cross-sectionally. A healthy lifestyle pattern (HLP) was determined using a score including: adherence to the Mediterranean diet, moderate alcohol consumption, expending …
Senile anorexia in acute-ward and rehabilitations settings.
2008
The most common pathological change in eating behaviour among older persons is anorexia, which accounts for a large percent of undernutrition in older adults. The main research aims are to determine, in a sample of acute and rehabilitation elderly subjects, the prevalence of anorexia of aging and the causes most impacting on senile anorexia.Methods: four different Units cooperated to this research study. Patients were recruited from geriatric acute and rehabilitation wards in Italy. Each Research Unit, for the estimation of the prevalence of anorexia in elderly subjects evaluated all the patients aged over 65 recruited from April 2006 to June 2007. Nutritional status, depression, social, fu…
Vertical Banded Gastroplasty Converted to Roux-en-Y Gastric Bypass: Little Impact on Nutritional Status after 5-Year Follow-up
2004
Background: Conversion to a Roux-en-Y gastric bypass (RYGBP) has been advocated after the failure of vertical banded gastroplasty (VBG). The aim of this study was to analyze the differences in anthropometric and nutritional parameters between patients with VBG and those converted to RYGBP. Methods: 45 patients initially underwent VBG. 22 of these patients have maintained this operation for more than 5 years (Group A) and 23 have been converted to RYGBP (Group B), after 2 years of follow-up. We analyzed anthropometric and nutritional parameters (macronutrients,micronutrients and lipid profile), and postoperative morbidity after both procedures. Data were recorded before the first operation a…
Biochemical risk indices, including plasma homocysteine, that prospectively predict mortality in older British people: the National Diet and Nutritio…
2010
Predictive power, for total and vascular mortality, of selected indices measured at baseline in the British National Diet and Nutrition Survey (community-living subset) of People Aged 65 Years and Over was tested. Mortality status and its primary and underlying causes were recorded for 1100 (mean age 76·7 (sd7·5) years, 50·2 % females) respondents from the baseline survey in 1994–5 until September 2008. Follow-up data analyses focussed especially on known predictors of vascular disease risk, together with intakes and status indices of selected nutrients known to affect, or to be affected by, these predictors. Total mortality was significantly predicted by hazard ratios of baseline plasma co…
Nutritional and global indexes of progression in dementia: a 12-month prospective study.
2012
Background: To assess the influence of body mass index (BMI) on the progression of dementia. Methods: Sixty elderly outpatients with untreated dementia followed for 12 months. All patients underwent clinical, cognitive, functional, and nutritional assessment at the baseline and after 12 months. Patients were divided into 2 groups by baseline BMI (< or ≥25 kg/m2). Results: Participants with a baseline BMI ≥25 kg/m2 had significantly higher Mini-Mental State Examination (MMSE) scores (21 ± 5.1 vs 15.9 ± 5.5; P < .001), while clinical dementia rating (CDR) and multidimensional prognostic index (MPI) scores were similar in the 2 groups. After 12 months, the MMSE score decreased significan…
