Efectos de la suplementación con glutamina sobre el sistema antioxidante y la peroxidación lipídica en pacientes críticos con nutrición parenteral

INTRODUCTION In the critically ill patient, there is a continuous production of reactive oxygen species (ROS) that need to be neutralized to prevent oxidative stress (OS). Quantitatively speaking, the glutathione system (GSH) is the most important anti-oxidant endogenous defense. To increase it, glutamine supplementation has been shown to be effective by protecting against the oxidative damage and reducing the morbimortality. OBJECTIVE To assess the effect of adding an alanylglutamine dipeptide to PN on lipid peroxidation lipidica and glutathione metabolism, as well as its relationship with morbidity in critically ill patients. METHODS Determination through spectrophotometry techniques of glutathione peroxidase, glutathione reductase, total glutathione, and maloniladdehyde at admission adn after seven days of hospitalization at the Intensive Care Unit (ICU) in 20 patients older than 18 years on parenteral nutrition therapy. RESULTS The group of patients receiving parenteral nutrition with glutamine supplementation had significant increases in total glutathione (42.35+/-13 vs 55.29+/-12 micromol/l; p<0.05) and the enzymatic activity of glutathione peroxidasa (470+/-195 vs 705+/-214 micromol/l; p<0.05) within one week of nutritional therapy, whereas the group on conventional parenteral nutrition did not show significant changes of any of the parameters studied (p>0.05). However, both mortality and ICU stay were not different between the study group, whereas the severity (assessed by the SOFA score) was lower in the group of patients receiving glutamine (SOFA 5+/-2 vs 8+/-1.8; p<0.05). CONCLUSIONS Glutamine intake in critically ill patients improves the antioxidant defenses, which leads to lower lipid peroxidation and lower morbidity during admission at the ICU.

Evolución de parámetros bioquímicos nutricionales en pacientes de hemodiálisis durante un año de seguimiento

Current high survival in hemodialysis patients (52% at 5 years) have made the chronic manifestations to emerge such as the high hyponutrition prevalence of these patients, as well as the importance of the nutritional status in their morbimortality. The reason for protein-caloric hyponutrition is multifactorial, although chronic inflammatory conditions associated to the dialysis technique are becoming more and more relevant. The variations in several nutritional biochemical parameters (total proteins, plasma albumin, transferrin, and total cholesterol) have been assessed in 73 hemodialysis patients for one year. The mean age of the patients was 53.3 +/- 18.69 years (43 males and 30 females). The average on hemodialysis program was 43 +/- 33 months, with a mean session duration of 246 +/- 24 minutes, and mean hemodialysis dose administered of 1.37 +/- 0.27 (KT/V) (second generation Daurgidas). A decrease in all the biochemical parameters assessed has been observed, with statistically significant differences: total proteins (p < 0.001), albumin (p < 0.00001), total cholesterol (p < 0.05), and transferrin (p < 0.01). The evolution of the nutritional biochemical parameters assessed showed an important nutritional deterioration of the patients remaining stable with the therapy.

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.

Prevalencia y factores asociados a desnutrición entre pacientes ingresados en un hospital de media-larga estancia

OBJECTIVES To determine the prevalence of hyponutrition at admission at a mid- to long-term stay hospital. To analyze the possible factors associated to hyponutrition; the possible relationship with mortality at one month, and the treatments for hyponutrition performed. MATERIALS AND METHOD Descriptive study from the laboratory data obtained in 140 patients. For diagnosing hyponutrition, a tool based on albumin, total cholesterol, and lymphocytes levels was used. Demographical (age and gender) and clinical data (presence of pressure soars, nasogastric tube, dementia, neoplasm, previous admission to the ICU, and main diagnosis) were gathered at admission as well as the mortality at the first month. The treatments used for hyponutrition were reviewed. RESULTS patients' age was 77.1 years and 63% were females. 17.1% of the patients presented normal nutritional status, 50.7% met the criteria for mild hyponutrition, 26.4% of moderate hyponutrition, and 5.7% of severe hyponutrition. We found no association between hyponutrition and gender, nasogastric tube, soars, dementia or neoplasm, but we did so with age (P = 0.033). We found a relationship between moderate-severe hyponutrition and pressure soars (P = 0.036). We found an association between hyponutrition and mortality at one month (OR = 1.357, 95% CI 1.121 to 1.643; P = 0.02). 35.6% of the patients with moderate-severe hyponutrition received therapy for this condition (28.9% with protein supplements and 6.7% with enteral diet). CONCLUSIONS hyponutrition affects most of the patients admitted to a mid to long-term stay hospitals and is associated with higher mortality. One third of hyponutrition patients receive nutritional therapy.

Comunicación paciente-médico y toma de decisiones en salud en Andalucía. Expectativas de pacientes crónicos del Sistema Sanitario Público Andaluz

The purpose of the study was to know about the expectations had by chronic patients within th e Public Healthcare System in Andalusi a, concerning commu nication and making deci sions with the med ical professionals who take care of them duri ng the entire treatment process. A qualitative study was carried out in Andalusia, based on 19 i n-depth interviews and 17 focus groups with 15 4 chronic patients and their relatives, suffering from seven different types of illness, of which the content was later analyzed based on the type of disease (pathologies), and the level of care (Primary, Sp eci aliz ed or Em ergen cy Ser vices). The study shows that patients i ncl uded in all healthcare processes want information about their illness. In Primary Care, they value continued attention, closeness and trust as well as being referred to a proper specialist. In Specialized Care, they expect to receive trustworthy information, proper tests and a correct diagnosis, friendly treatment and to be listened to. In the Emergency Room, lack of tim e and overcrowding d i sru pt proper communic ation. The type of chronic illne ss i nfluenc es patients’ expectations in terms of communication and decisionmaking. Communic ation between patients and medical personnel and the decision-making process related to chronic illness are crucial for the improvement of the qualit y o f healthcare. The type of chr onic disease marks diffe rent expectation s about the communication and decision-making. The communication and the decision making in the chronic assistance is a priority to improve the quality of the assistance

¿Quién acompaña a los pacientes a la consulta pediátrica? El acompañante de los pacientes pediátricos en Atención Primaria

Introduction: today, cultural changes may have changed the usual pattern of the mother as the accompanying person in the pediatric office. Objetives: descriptive analysis of the current situation in the pediatrics office. Material and methods: Las Delicias Health Center (health district of Malaga). Selected sample of 250 patients between the periods 1-15 July and 15-30 September, 2011. Results: in most cases (54.8%), the mother stands as the main accompanying person, appearing both parents in the consultation in 16.4% of cases. The figure of the grandparents is of special significance when the mother is an active worker. Most consultations were on-demand by appointment (82.4%), for acute symptoms, with symptoms lasting less than 3 days in most cases (59.2%). Discussion: the mother is presented as the main accompanying person in most cases. The father or grandparents will be present in front of social-cultural factors, mainly active employment status of the mother.
