Influencia de la temperatura en la ingesta de pacientes hospitalizados.

BACKGROUND AND OBJECTIVES Prevalence of hyponutrition in hospitalized patients is very high and it has been shown to be an important prognostic factor. Most of admitted patients depend on hospital food to cover their nutritional demands being important to assess the factors influencing their intake, which may be modified in order to improve it and prevent the consequences of inadequate feeding. In previous works, it has been shown that one of the worst scored characteristics of dishes was the temperature. The aim of this study was to assess the influence of temperature on patient's satisfaction and amount eaten depending on whether the food was served in isothermal trolleys keeping proper food temperature or not. MATERIAL AND METHODS We carried out satisfaction surveys to hospitalized patients having regular diets, served with or without isothermal trolleys. The following data were gathered: age, gender, weight, number of visits, mobility, autonomy, amount of orally taken medication, intake of out-of-hospital foods, qualification of food temperature, presentation and smokiness, amount of food eaten, and reasons for not eating all the content of the tray. RESULTS Of the 363 surveys, 134 (37.96%) were done to patients with isothermal trays and 229 (62.04%) to patients without them. Sixty percent of the patients referred having eaten less than the normal amount within the last week, the most frequent reason being decreased appetite. During lunch and dinner, 69.3% and 67.7%, respectively, ate half or less of the tray content, the main reasons being as follows: lack of appetite (42% at lunch time and 40% at dinner), do not like the food (24.3 and 26.2%) or taste (15.3 and 16.8%). Other less common reasons were the odor, the amount of food, having nausea or vomiting, fatigue, and lack of autonomy. There were no significant differences in the amount eaten by gender, weight, number of visits, amount of medication, and level of physical activity. The food temperature was classified as adequate by 62% of the patients, the presentation by 95%, and smokiness by 85%. When comparing the patients served with or without isothermal trays, there were no differences with regards to baseline characteristics analyzed that might have had an influence on amount eaten. Ninety percent of the patients with isothermal trolley rated the food temperature as good, as compared with 57.2% of the patients with conventional trolley, the difference being statistically significant (P = 0.000). Besides, there were differences in the amount of food eaten between patients with and without isothermal trolley, so that 41% and 27.7% ate all the tray content, respectively, difference being statistically significant (P = 0.007). There were no differences in smokiness or presentation rating. CONCLUSIONS Most of the patients (60%) had decreased appetite during hospital admission. The percentage of hospitalized patients rating the food temperature as being good is higher among patients served with isothermal trolleys. The amount of food eaten by the patients served with isothermal trolleys is significantly higher that in those without them.

Estudio longitudinal del Índice de masa corporal (IMC) en pacientes en diálisis

Chronic renal failure is commonly related to hyponutrition, affecting approximately on third of patients with advanced renal failure. We carried out a longitudinal study to assess nutritional evolution of 73 patients on a regular hemodialysis program, assessing changes in the anthropometrical parameter body mass index (BMI) and its correspondence to biochemical nutritional parameters such as total protein (TP) levels and serum albumin (Alb). Every three months plasma TP and albumin levels were collected and BMI was calculated by the standard formula: post-dialysis weight in kg/height in m2. For classifying by BMI categories, overweight and low weight were defined according to the WHO Expert Committee. Studied patients had a mean age of 53 years, 43 were male and 30 were female patients. BMI in women was lower than that in men (p < 0.001), as well as TP (p < 0.001) and Alb (p < 0.001) levels. Mean BMI was 29.3 kg/m2. Three point two percent of the determinations showed low weight, 12.16% overweight, and 83.97% normal BMI. TP were normal in 90.76% and decreased in 9.24%. Alb was normal in 82.2% and low in 17.78%. After the follow-up time (21.6 months, minimum 18 months, maximum 53 months), the Kruskal-Wallis test did not show a statistically significant change for BMI but it did show a change for the biochemical parameters albumin and total proteins (p < 0.05): nutritional impairment in CRF patients is manifested on biochemical parameters (TP and Alb) with no reflection on anthropometrical data.

Estudio longitudinal del peso e índice de masa corporal tras el trasplante renal durante 5 años de evolución.

INTRODUCTION: Gain weight after transplantation is relatively common, also tends to be multifactorial and can be influenced by glucocorticoids and immunosuppressive medications, delayed graft function and cause serious health complications. OBJECTIVES: Assess changes in weight, degree of obesity and body mass index as well as the effect of immunosuppressive treatment over these 5 years after kidney transplantation. METHODS: The samples were 119 kidney transplant recipients, 70 men and 49 women, that attended the query post for five years. All patients were measured Pretransplant and post (from 1st year to the 5th year) weight, height and body mass index calculated by the formula weight/size2 relating it to immunosuppressive treatment taking. RESULTS: There is a considerable increase of body mass index, weight and degree of obesity in the first year after transplantation to increase more slowly in the next four years. The type of immunosuppressive treatment influence the weight and degree of obesity that occurs in this period of time. CONCLUSIONS: A high prevalence there are overweight and obesity after the transplant especially during the first year. A year patients earn an average of 6.6 kg in weight and an average of 2.5 kg/m2 in their BMI. During treatment should minimize doses of steroids and include dietary treatment and adequate physical exercise

Relación entre la edad, el índice de masa corporal, el grado de dependencia y la calidad de vida en pacientes con desnutrición tras un alta hospitalaria.

Introduction: The quality of life assessment means investigating how patients perceive their disease. Malnutrition-specific characteristics make patients more vulnerable, so it is important to know how these factors impaction patients’ daily life. Aim: To assess the quality of life in malnourished patients who have had hospital admission, and to determine the relationship of the quality of life with age, body mass index, diagnosis of malnutrition, and dependency. Method: Multicenter transversal descriptive study in 106 malnourished patients after hospital admission. The quality of life (SF-12 questionnaire), BMI, functional independency (Barthel index), morbidity, and a dietary intake evaluation were assessed. The relationship between variables was tested by using the Spearman correlation coefficient Results: The patients of the present study showed a SF-12 mean of 38.32 points. The age was significantly correlated with the SF-12 (r= -0.320, p= 0.001). The BMI was correlated with the SF-12 (r= 0.251, p= 0.011) and its mental component (r= 0.289, p= 0.03). It was also reported a significant correlation between the Barthel index and the SF-12 (r= 0.370, p< 0.001). Conclusions: The general health perception in malnourished patients who have had a hospital admission was lower than the Spanish mean. Moreover, the quality of life in these patients is significantly correlated with age, BMI and functional independency.

Osteoporosis e índice de masa corporal en el trasplantado renal.

INTRODUCTION: frequently after kidney transplantation there is an increase in weight with a resulting high percent of obesity in these recipients. This combined with a rapid loss of bone mass, a higher prevalence of osteoporosis and fractures is evident than in normal populations. OBJECTIVES: to explore the relationship between body mass index (BMI) and prevalence of osteoporosis in a population of renal transplant recipients. METHODS: prospective longitudinal study design. The study was conducted on 306 kidney transplant recipients. The relationship between weigh and body mass index with femoral and lumbar osteopenia and osteoporosis prevalence at the moment of transplant and at 12 months post was explored. RESULTS: there was a high prevalence of overweight (35.6%) and obese (14.1%) recipients after renal transplant and 1 year after (42.2% and 24.2% respectively). Significant differences were found(p = 0.049) between the weight at the time of transplant and the presence of osteopenia or osteoporosis at the lumbar level one year after, the highest weights were in recipients with osteoporosis. The mean BMI was higher (p = 0.028) in osteoporotic patients (26.59 kg/m2) than in patients with osteopenia (24.23 kg/m2). CONCLUSION: results seem to be consistent with recent studies in the general population showing excessive weight as a possible factor detrimental to the bone health.

Estudio de la albúmina sérica y del índice de masa corporal como marcadores nutricionales en pacientes en hemodiálisis.

Background: Protein calorie malnutrition as well as systemic inflammation and metabolic disorders are common among patients with chronic renal failure undergoing renal replacement therapy (haemodialysis), which contributes to its morbidity and mortality. Aims: The aims of this work was to evaluate the nutritional status of patients in a hemodialysis treatment through the assessment of biochemical parameters nutritional as albumin, and anthropometric parameters of body mass index during ten years of follow up. Methods: In this work has been followed 90 patients of both sexes with chronic kidney disease who were treated with hemodialysis regularly on our unit for ten years. All patients were conducted quarterly measurements of plasma albumin (Alb), and other biochemical determinations, and anthropometric measurements of height, weight and body mass index calculated by the formula weight/height², grouped n BMI < 23 kg/m2 and albumin levels <3.8 g/dl according to the consensus of the panel of experts of the International Society for renal Nutrition and metabolism. Results: During the 10 years all patients showed a significant decline in the biochemical parameters and the albumin, change in BMI does not presented significant changes in relation to malnutrition. Conclusions: Malnutrition in patients on dialysis is a fact patent, BMI does not correspond with the biochemical parameters were observed, for what nutritional impairment in these patients is mainly expressed by serum albumin.
