RESUMO

BACKGROUND: Stroke patients often face disabilities that significantly interfere with their daily lives. Poor nutritional status is a common issue amongst these patients, and malnutrition can severely impact their functional recovery post-stroke. Therefore, nutritional therapy is crucial in managing stroke outcomes. However, its effects on disability, activities of daily living (ADL), and other critical outcomes have not been fully explored. OBJECTIVES: To evaluate the effects of nutritional therapy on reducing disability and improving ADL in patients after stroke. SEARCH METHODS: We searched the trial registers of the Cochrane Stroke Group, CENTRAL, MEDLINE (from 1946), Embase (from 1974), CINAHL (from 1982), and AMED (from 1985) to 19 February 2024. We also searched trials and research registries (ClinicalTrials.gov, World Health Organization International Clinical Trials Registry Platform) and reference lists of articles. SELECTION CRITERIA: We included randomised controlled trials (RCTs) that compared nutritional therapy with placebo, usual care, or one type of nutritional therapy in people after stroke. Nutritional therapy was defined as the administration of supplemental nutrients, including energy, protein, amino acids, fatty acids, vitamins, and minerals, through oral, enteral, or parenteral methods. As a comparator, one type of nutritional therapy refers to all forms of nutritional therapies, excluding the specific nutritional therapy defined for use in the intervention group. DATA COLLECTION AND ANALYSIS: We used Cochrane's Screen4Me workflow to assess the initial search results. Two review authors independently screened references that met the inclusion criteria, extracted data, and assessed the risk of bias and the certainty of the evidence using the GRADE approach. We calculated the mean difference (MD) or standardised mean difference (SMD) for continuous data and the odds ratio (OR) for dichotomous data, with 95% confidence intervals (CIs). We assessed heterogeneity using the I2 statistic. The primary outcomes were disability and ADL. We also assessed gait, nutritional status, all-cause mortality, quality of life, hand and leg muscle strength, cognitive function, physical performance, stroke recurrence, swallowing function, neurological impairment, and the development of complications (adverse events) as secondary outcomes. MAIN RESULTS: We identified 52 eligible RCTs involving 11,926 participants. Thirty-six studies were conducted in the acute phase, 10 in the subacute phase, three in the acute and subacute phases, and three in the chronic phase. Twenty-three studies included patients with ischaemic stroke, three included patients with haemorrhagic stroke, three included patients with subarachnoid haemorrhage (SAH), and 23 included patients with ischaemic or haemorrhagic stroke including SAH. There were 25 types of nutritional supplements used as an intervention. The number of studies that assessed disability and ADL as outcomes were nine and 17, respectively. For the intervention using oral energy and protein supplements, which was a primary intervention in this review, six studies were included. The results for the seven outcomes focused on (disability, ADL, body weight change, all-cause mortality, gait speed, quality of life, and incidence of complications (adverse events)) were as follows: There was no evidence of a difference in reducing disability when 'good status' was defined as an mRS score of 0 to 2 (for 'good status': OR 0.97, 95% CI 0.86 to 1.10; 1 RCT, 4023 participants; low-certainty evidence). Oral energy and protein supplements may improve ADL as indicated by an increase in the FIM motor score, but the evidence is very uncertain (MD 8.74, 95% CI 5.93 to 11.54; 2 RCTs, 165 participants; very low-certainty evidence). Oral energy and protein supplements may increase body weight, but the evidence is very uncertain (MD 0.90, 95% CI 0.23 to 1.58; 3 RCTs, 205 participants; very low-certainty evidence). There was no evidence of a difference in reducing all-cause mortality (OR 0.57, 95% CI 0.14 to 2.28; 2 RCTs, 4065 participants; low-certainty evidence). For gait speed and quality of life, no study was identified. With regard to incidence of complications (adverse events), there was no evidence of a difference in the incidence of infections, including pneumonia, urinary tract infections, and septicaemia (OR 0.68, 95% CI 0.20 to 2.30; 1 RCT, 42 participants; very low-certainty evidence). The intervention was associated with an increased incidence of diarrhoea compared to usual care (OR 4.29, 95% CI 1.98 to 9.28; 1 RCT, 4023 participants; low-certainty evidence) and the occurrence of hyperglycaemia or hypoglycaemia (OR 15.6, 95% CI 4.84 to 50.23; 1 RCT, 4023 participants; low-certainty evidence). AUTHORS' CONCLUSIONS: We are uncertain about the effect of nutritional therapy, including oral energy and protein supplements and other supplements identified in this review, on reducing disability and improving ADL in people after stroke. Various nutritional interventions were assessed for the outcomes in the included studies, and almost all studies had small sample sizes. This led to challenges in conducting meta-analyses and reduced the precision of the evidence. Moreover, most of the studies had issues with the risk of bias, especially in terms of the absence of blinding and unclear information. Regarding adverse events, the intervention with oral energy and protein supplements was associated with a higher number of adverse events, such as diarrhoea, hyperglycaemia, and hypoglycaemia, compared to usual care. However, the quality of the evidence was low. Given the low certainty of most of the evidence in our review, further research is needed. Future research should focus on targeted nutritional interventions to reduce disability and improve ADL based on a theoretical rationale in people after stroke and there is a need for improved methodology and reporting.

RESUMO

BACKGROUND AND AIMS: Hospitalized patients often have acute kidney disease (AKD) or chronic kidney disease (CKD), with important metabolic and nutritional consequences. Moreover, in case kidney replacement therapy (KRT) is started, the possible impact on nutritional requirements cannot be neglected. On this regard, the present guideline aims to provide evidence-based recommendations for clinical nutrition in hospitalized patients with KD. METHODS: The standard operating procedure for ESPEN guidelines was used. Clinical questions were defined in both the PICO format, and organized in subtopics when needed, and in non-PICO questions for the more general topics. The literature search was from January 1st, 1999 until January 1st, 2020. Each question led to one or more recommendation/statement and related commentaries. Existing evidence was graded, as well as recommendations and statements were developed and agreed upon in a multistage consensus process. RESULTS: The present guideline provides 32 evidence-based recommendations and 8 statements, defining how to assess nutritional status, how to define patients at risk, how to choose the route of feeding, and how to integrate nutrition with KRT. In the final online voting, a strong consensus was reached in 84% at least of recommendations and 100% of statements. CONCLUSION: The presence of KD in hospitalized patients identifies a highly heterogeneous group of subjects with widely varying nutrient needs and intakes. Considering the high nutritional risk related with this clinical condition, an individualized approach consisting of nutritional status evaluation and monitoring, frequent evaluation of nutritional requirements, and careful integration with KRT should be planned to avoid both underfeeding and overfeeding. Practical recommendations and statements were developed, aiming at defining suggestions for everyday clinical practice in the individualization of nutritional support in this patient setting. Literature areas with scarce or without evidence were also identified, thus requiring further basic or clinical research.

RESUMO

Background: Clinical nutritionists are responsible for nutritional therapy in clinical practice, which significantly enhances patients' nutritional status. This study aims to develop and validate a competency evaluation scale to effectively assess the abilities of clinical nutritionists. Methods: The competency evaluation scale for clinical nutritionists was developed based on the iceberg model, utilizing literature review, semi-structured interviews, and the Delphi method. The weights of each indicator were calculated using the Analytic Hierarchy Process (AHP), and the validity and reliability of the scale were confirmed through questionnaire surveys. Results: The competency evaluation scale of clinical nutritionists comprised five primary indicators, twelve secondary indicators, and sixty-six tertiary indicators. The primary indicators, including professional theoretical knowledge, professional practical skills, humanistic practice ability, interpersonal communication ability, and professional development capability, have respective weights of 0.2168, 0.2120, 0.2042, 0.2022, and 0.1649. The Cronbach's α coefficients of the five dimensions of the scale were 0.970, 0.978, 0.969, 0.962, and 0.947, respectively. The results of the Exploratory Factor Analysis showed that the prerequisites for factor analysis were satisfied. Additionally, Bartlett's test of sphericity yielded a significance level of p < 0.001, confirming the scale's reliability and validity. Conclusions: The competency evaluation scale for clinical nutritionists developed in this study is of high scientific reliability and validity, which provides assessment criteria for the training and assessment of clinical nutritionists.

RESUMO

Care transitions from hospital to home for older adults with malnutrition present a period of elevated risk; however, minimal data exist describing the existing practice. This study aimed to describe the transition of nutrition care processes provided to older adults in a public tertiary hospital in Australia. A retrospective chart audit conducted between July and October 2022 included older (≥65 years), malnourished adults discharged to independent living. Dietetic care practices (from inpatient to six-months post-discharge) were reported descriptively. Of 3466 consecutive admissions, 345 (10%) had a diagnosis of malnutrition documented by the dietitian and were included in the analysis. The median number of dietetic visits per admission was 2.0 (IQR 1.0-4.0). Nutrition-focused discharge plans were inconsistently developed and documented. Only 10% of patients had nutrition care recommendations documented in the electronic discharge summary. Post-discharge oral nutrition supplementation was offered to 46% and accepted by 34% of the patients, while only 23% attended a follow-up appointment with dietetics within six months of hospital discharge. Most patients who are seen by dietitians and diagnosed with malnutrition appear lost in transition from hospital to home. Ongoing work is required to explore determinants of post-discharge nutrition care in this vulnerable population.

RESUMO

Most randomized controlled studies on nutrition in intensive care patients did not yield conclusive results or were neutral or negative concerning the primary endpoints but also in most secondary endpoints. However, there is a consistent observation that in several of these studies there was a negative effect of the nutrition intervention on the kidneys in one of the study arms. During the early phase and in unstable periods during further course of disease an inadequate clinical nutrition can damage the kidneys, can elicit or aggravate acute kidney injury and/ or increase requirements of renal replacement therapy (RRT). This relates to total energy intake, glucose intake/hyperglycemia and protein/ amino acid intake at various stages of renal dysfunction. The kidney could present a critical organ system for guiding nutrition therapy, a close monitoring of kidney function should be observed and nutrition therapy may need to be adapted accordingly. The long-held dogma of performing full nutrition and accept an otherwise not necessary RRT is definitely to be refuted.

RESUMO

Obesity is a complex chronic disease with increasing prevalence across the globe. Medical nutrition therapy (MNT) is an important component of obesity treatment, and low-calorie diets (LCDs) and very-low-calorie diets (VLCDs) are part of the MNT toolbox. This narrative review focuses on the latest evidence and clinical guidelines regarding the use and impact of meal replacements (MRs) as part of LCDs/VLCDs for the treatment of obesity and some associated complications. MRs can be used in conjunction with food as partial diet replacement (PDR) or can be used exclusively to serve as the sole source of dietary energy (total diet replacement [TDR]). Use of MR may be associated with better control of cravings and hunger typically observed during reduced calorie intake through effects of ketosis or stimuli narrowing, although the exact mechanisms for these effects remain unclear. Several clinical guidelines have endorsed the use of MRs as a part of MNT for obesity, primarily based on evidence that shows an average weight reduction of ~10 kg or more with TDR over at least 12 months in large, randomized controlled trials. When compared to usual care controls, these effects are 6-8 kg greater, and when compared to food-based diets, the effects are nearly twice the effect of a food-based diet. MR-based diets have been found to be safe and associated with improvements in quality of life. These diets are also effective for improving key cardiometabolic health outcomes, including dysglycaemia, blood pressure, lipids, and metabolic associated fatty liver. The effectiveness, safety, and associated health improvement makes MRs use a valuable strategy for several higher risk clinical scenarios where weight reduction is indicated.

RESUMO

BACKGROUND AND OBJECTIVES: Study aim was to determine the levels and barriers of the Nutrition Care Process (NCP), a practical method of individualized nutrition support. METHODS AND STUDY DESIGN: Delegate of registered dietitians (RDs) from acute-care hospitals answered our nationwide web-based questionnaire (April-June, 2023) to determine the implementation status of screening, assessment, intervention (including planning), and monitoring (components of the NCP). RESULTS: Of 5,378 institutions contacted, 905 (16.8%) responded. For Screening, 80.0% screened all inpatients: primary personnel in charge were RDs (57.6%); the most used screening tool was Subjective Global Assessment (SGA) (49.2%). For Assessment, 66.1% assessed all inpatients: food intake (93.3%) was most evaluated whereas muscle mass and strength (13.0%, 8.8%) were least evaluated. For Intervention, 43.9% did so within 48h of hospital admission: oral nutritional supplement (92.9%) was the most common RDs intervention and parenteral nutrition (29.9%) was used less. For Monitoring, 18.5% of institutions had monitoring frequency of ≥ 3 times/week whilst 23.0% had monitoring less than once a week for severely malnourished patients. Energy and protein intake (93.7%, 84.3%) were most monitored and lipid intake (30.1%) was less monitored. CONCLUSIONS: Barriers of NCP included inefficient staffing systems and unsuitable tools in Screening, inaccurate patient targeting and lack of important evaluation items in Assessment, delayed timing and incomplete contents in Intervention, and inadequate fre-quency and lack of important evaluation items in Monitoring. An increase in RDs staffing in acute-care general wards, widespread NCP instruction manuals, and education about the tools and evaluation items utilized in nutritional management are possible solutions.

RESUMO

BACKGROUND: Type-2 Diabetes Mellitus (T2D) is a growing concern worldwide, and family doctors are called to help diabetic patients manage this chronic disease, also with Medical Nutrition Therapy (MNT). However, MNT for Diabetes is usually standardized, while it would be much more effective if tailored to the patient. There is a gap in patient-tailored MNT which, if addressed, could support family doctors in delivering effective recommendations. In this context, decision support systems (DSSs) are valuable tools for physicians to support MNT for T2D patients - as long as DSSs are transparent to humans in their decision-making process. Indeed, the lack of transparency in data-driven DSS might hinder their adoption in clinical practice, thus leaving family physicians to adopt general nutrition guidelines provided by the national healthcare systems. METHOD: This work presents a prototypical ontology-based clinical Decision Support System (OnT2D- DSS) aimed at assisting general practice doctors in managing T2D patients, specifically in creating a tailored dietary plan, leveraging clinical expert knowledge. OnT2D-DSS exploits clinical expert knowledge formalized as a domain ontology to identify a patient's phenotype and potential comorbidities, providing personalized MNT recommendations for macro- and micro-nutrient intake. The system can be accessed via a prototypical interface. RESULTS: Two preliminary experiments are conducted to assess both the quality and correctness of the inferences provided by the system and the usability and acceptance of the OnT2D-DSS (conducted with nutrition experts and family doctors, respectively). CONCLUSIONS: Overall, the system is deemed accurate by the nutrition experts and valuable by the family doctors, with minor suggestions for future improvements collected during the experiments.

RESUMO

For artificial intelligence (AI) to support nutrition care, high quality and accuracy of its features within smartphone applications (apps) are essential. This study evaluated popular apps' features, quality, behaviour change potential, and comparative validity of dietary assessment via manual logging and AI. The top 200 free and paid nutrition-related apps from Australia's Apple App and Google Play stores were screened (n = 800). Apps were assessed using MARS (quality) and ABACUS (behaviour change potential). Nutritional outputs from manual food logging and AI-enabled food-image recognition apps were compared with food records for Western, Asian, and Recommended diets. Among 18 apps, Noom scored highest on MARS (mean = 4.44) and ABACUS (21/21). From 16 manual food-logging apps, energy was overestimated for Western (mean: 1040 kJ) but underestimated for Asian (mean: -1520 kJ) diets. MyFitnessPal and Fastic had the highest accuracy (97% and 92%, respectively) out of seven AI-enabled food image recognition apps. Apps with more AI integration demonstrated better functionality, but automatic energy estimations from AI-enabled food image recognition were inaccurate. To enhance the integration of apps into nutrition care, collaborating with dietitians is essential for improving their credibility and comparative validity by expanding food databases. Moreover, training AI models are needed to improve AI-enabled food recognition, especially for mixed dishes and culturally diverse foods.

RESUMO

BACKGROUND: Comfort-focused nutrition orders are recommended to manage eating changes among long-term care (LTC) residents nearing the end of life, though little is known about their current use. This investigation aims to describe current practices and identify resident-level and time-dependent factors associated with comfort-focused nutrition orders in this context. METHODS: Data were retrospectively extracted from resident charts of decedents (≥65 years at death, admitted ≥6 months) in 18 LTC homes from two sampling frames across southern Ontario, Canada. Observations occurred at 6 months (baseline), 3 months, 1 month and 2 weeks prior to death. Extracted data included functional measures (e.g. cognitive performance, health instability) at baseline, formalised restorative and comfort-focused nutrition care interventions at each timepoint and eating changes reported in the progress notes in 2 weeks following each timepoint. Logistic regression and time-varying logistic regression models determined resident-level (e.g. functional characteristics) and time-dependent factors (e.g. eating changes) associated with receiving a comfort-focused nutrition order. RESULTS: Less than one-third (30.5%; n = 50) of 164 participants (61.0% female; mean age = 88.3 ± 7.5 years) received a comfort-focused nutrition order, whereas most (99%) received at least one restorative nutrition intervention to support oral food intake. Discontinuation of nutrition interventions was rare (8.5%). Comfort orders were more likely with health instability (OR [95% CI] = 4.35 [1.49, 13.76]), within 2 weeks of death (OR = 5.50 [1.70, 17.11]), when an end-of-life conversation had occurred since the previous timepoint (OR = 5.66 [2.83, 11.33]), with discontinued nutrition interventions (OR = 6.31 [1.75, 22.72]), with co-occurrence of other care plan modifications (OR = 1.48 [1.10, 1.98]) and with a greater number of eating changes (OR = 1.19 [1.02, 1.38]), especially dysphagia (OR = 2.59 [1.09, 6.17]), at the preceding timepoint. CONCLUSIONS: Comfort-focused nutrition orders were initiated for less than one-third of decedents and most often in the end stages of life, possibly representing missed opportunities to support the quality of life for this vulnerable population. An increase in eating changes, including new dysphagia, may signal a need for proactive end-of-life conversations involving comfort nutrition care options. IMPLICATIONS FOR PRACTICE: Early and open conversations with residents and family about potential eating changes and comfort-focused nutrition care options should be encouraged and planned for among geriatric nursing teams working in LTC. These conversations may be beneficial even as early as resident admission to the home.

RESUMO

Objectives: Non-invasive ventilation use is increasing in patients from acute respiratory failure. However, nutritional assessment and medical nutritional therapy are often missed and patients may be frequently underfed. This review evaluates the tools for nutritional screening and assessment, assesses the use of medical nutritional therapy in various techniques of non invasive ventilation and suggested tools to improve this therapy. Methods, results: A review of the literature was performed to evaluate the tools available to define malnutrition and determine the energy needs of patients requiring non invasive ventilation. Energy and protein intake was assessed in 16 recent papers. High Flow Nasal Cannula Oxygen therapy and non invasive ventilation using mask were described and nutritional therapy determined in each condition.The Global Leadership International Malnutrition Assessment seems to be the best assessment to be recommended. Energy expenditure is optimally obtained by indirect calorimetry. Patients with Non invasive ventilation are even more underfed than patients receiving High Flow Nasal Cannula Oxygen therapy. Conclusions: A better determination of malnutrition, a more adequate energy requirement and an improved energy and protein administration are required in patients with acute respiratory failure treated with non invasive ventilation.

RESUMO

Obesity stands out as a primary risk factor for diabetes. Attaining healthy weight loss, especially reducing body fat, is important in managing prediabetes and preventing progression to full diabetes and its co-morbidities. This study examined the effects of personalized nutrition therapy (PNT) combined with continuous glucose monitoring (CGM) on body weight and composition in individuals with prediabetes. A total of 30 individuals with prediabetes who were overweight or obese were assigned randomly to either the treatment, observed CGM data plus PNT, or the control group which was blinded to their blood glucose results throughout the study. Both groups were provided with dietary recommendations for calorie intake and macronutrient distribution, coupled with personalized goal setting for glucose control and healthy eating, without any specific emphasis on weight reduction or changes in physical activity. Regular visits were scheduled every 10 days to perform measurements and replace CGMs. Data were analyzed using General Linear Model with repeated measures. Over the 30-day follow-up period, both groups experienced significant reductions in weight and fat mass. The treatment group exhibited two-fold greater reductions in both weight and fat mass, a significant decrease in carbohydrate intake, and a significant increase in time spent on physical activitycompared to the control group. In addition, compliance was notably higher in the treatment group. These findings indicate that overweight or obese individuals with prediabetes can achieve weight loss and improved body composition through personalized education for glucose control, without exclusively emphasizing weight loss as the primary objective. Additionally, the real-time feedback provided by CGM enhances these improvements.

RESUMO

A useful perioperative nutritional therapy for highly invasive esophageal cancer surgical cases needs to be developed. We clarified the usefulness of amino-acid-enriched nutritional therapy using glutamine (Gln)/arginine (Arg)/calcium ß-hydroxy-ß-methylbutyrate (HMB) products on the short-term postoperative outcomes of minimally invasive esophagectomy for esophageal cancer. Altogether, 114 patients (Gln/Arg/HMB group) received perioperative nutritional therapy with Gln/Arg/HMB products, and we retrospectively investigated the change in nutritional parameters including skeletal muscle mass, occurrence of postoperative complications, and short-term postoperative outcomes in this group. The results were compared between the Gln/Arg/HMB and control groups (79 patients not receiving the Gln/Arg/HMB products). The incidence of all postoperative complications, sputum expectoration disorder, and pleural effusion of grade ≥ III was significantly lower in the Gln/Arg/HMB group (62.0% vs. 38.6%, p = 0.001; 44.3% vs. 28.1%, p = 0.020; 27.8% vs. 13.2%, p = 0.011, respectively). The psoas muscle area and postoperative body weight were significantly higher at 1 month and 1 year after surgery in the Gln/Arg/HMB group than in the control group (93.5% vs. 99.9%, p < 0.001; 92.0% vs. 95.4%, p = 0.006). Perioperative amino-acid-enriched nutritional therapy may improve the short-term postoperative outcomes, nutritional status, and skeletal muscle mass of esophageal cancer surgical patients.

RESUMO

Micronutrients (MN), i.e. trace elements and vitamins, are essential organic molecules, which are required in the diet in relatively small amounts in any form of nutrition (oral, enteral, parenteral). The probability of MN depletion or deficiencies should be considered in all chronic illnesses, especially in those that can interfere with intake, digestion, or intestinal absorption. Low socio-economic status and food deprivation are recognized as the most prevalent reasons for MN deficiencies world-wide. Elderly multimorbid patients with multimodal therapy, as well as patients with long-lasting menu restrictions, are at high risk for both disease related malnutrition as well as multiple MN deficiencies, needing careful specific follow-up. The importance of monitoring MN blood levels along with CRP is essential for optimal care. Drug interactions are also highlighted. In patients with chronic conditions depending on medical nutrition therapy, the provision of adequate dietary reference intakes (DRI) of MN doses and monitoring of their adequacy belongs to standard of care.

RESUMO

The need for improved nutrition in older adults requiring care has been acknowledged, but, to the best of our knowledge, there is a lack of systematic review and integration of nutritional care studies with older adults in nursing homes. This scoping review aimed to examine the scope and nature of nutritional care research for older adults in nursing homes and to identify research gaps, following the guidelines of the Joanna Briggs Institute. We found varied nutritional care for older adults living in nursing homes, including individualized sessions, such as nutrition counseling, the addition of foods and preparations for increased nutritional intake, and the maintenance of an eating environment, such as feeding assistance and calling. The nutritional care identified in this scoping review also included studies that have improved the nutritional status of older adults in nursing homes by implementing educational programs for care staff. For future research on effective nutritional care for older adults in nursing homes, we suggest evaluating both short- and long-term intervention effects with an adequate sample size.

RESUMO

The level of NCP implementation varies across countries due to differences identified in major components of health systems such as infrastructures, legislation, training, and cultural diversities. Dietitians in Greece receive sufficient training in the implementation of the NCP as part of their main studies; however, the level of awareness and adoption of the NCP model is still quite low, with limited information on the potential barriers. The primary aim of this study was to gain a deeper understanding of the perspectives of Greek dietitians on the NCP and the use of digital tools. An online survey was created and distributed through the platform "SurveyMonkey version 4.1.1". The overall structure of the questionnaire was modeled according to the validated NCP/NCPT INIS Tool. A total of 279 subjects were included in this study, and 192 were aware of the NCP tool. The most important challenges for the implementation of the NCP included communication with other healthcare professionals (68.2%), provision of appropriate care (33.9%), and insufficient access to continuous education (29.2%). Of the 192 participants who knew the NCP, 81.3% reported using digital applications for the collection and assessment of health data, while 18.8% indicated that they did not utilize such tools. No relationship was found between the use of digital applications by dietitians, NCP knowledge, and demographic characteristics. Our findings highlight the need for targeted educational interventions and appropriate application of standardized protocols by Greek dietitians in daily practice. National Dietetic Associations should provide sufficient guidance on digital tool utilization in facilitating patient data management and enhancing NCP implementation.

RESUMO

Introduction: Introduction: medical nutritional treatment (MNT) can be complex and may be associated with potential metabolic complications, which has been recently described as nutritrauma. Objective: the aim of our work is to describe whether the application of the nutritrauma concept in real life is feasible and useful to detect the metabolic complications associated with the prescription of MNT. Material and methods: in this descriptive, prospective study at a single center we enrolled 30 consecutive critically ill patients in a 14-bed medical-surgical intensive care unit. The nutritrauma strategy implementation was based in four "M" steps: Metabolic screening, MNT prescription, biochemical Monitoring, and nutritional Management. Results: we analyzed 28 patients (mean age, 69.7 ± 11.3 years; APACHE II, 18.1 ± 8.1; SOFA, 7.5 ± 3.7; Nutric Score, modified, 4.3 ± 2.01, and mean BMI, 27.2 ± 3.8). The main cause of admission was sepsis (46.4 %). Length of ICU stay was 20.6 ± 15.1 days; 39.3 % of subjects died during their ICU stay. Enteral nutrition (82.1 %) was more frequent than parenteral nutrition (17.9 %). During nutritional monitoring, 54 specific laboratory determinations were made. Hyperglycemia was the most frequent metabolic alteration (83.3 % of measurements). Electrolyte disturbances included hypocalcemia (50 %), hypophosphatemia (29.6 %) and hypokalemia (27.8 %). The most frequent lipid profile abnormalities were hypocholesterolemia (64.8 %) and hypertriglyceridemia (27.8 %). Furthermore, nutritional prescription was modified for 53.6 % of patients: increased protein dosage (25 %), increased calorie dosage (21.4 %) and change to organ-specific diet (17.8 %). Conclusions: in conclusion, the application of the nutritrauma approach facilitates detection of metabolic complications and an evaluation of the appropriate prescription of MNT.


Introducción: Introducción: el tratamiento médico nutricional (TMN) puede ser complejo y asociarse a potenciales complicaciones metabólicas, lo que se ha descrito recientemente como "nutritrauma". Objetivo: el objetivo de nuestro trabajo es describir si la aplicación del concepto de nutritrauma en la vida real es factible y útil para detectar las complicaciones metabólicas asociadas a la prescripción del TMN. Materiales y métodos: en este estudio unicéntrico y prospectivo describimos el seguimiento de 30 pacientes críticos consecutivos en una unidad de cuidados intensivos médico-quirúrgica de 14 camas. La implementación de la estrategia nutritrauma se basó en cuatro pasos "M": valoración Metabólica, prescripción del TMN, Monitorización bioquímica y Manejo nutricional. Resultados: se analizaron 28 pacientes (edad media: 69,7 ± 11,3 años; APACHE II: 18,1 ± 8,1; SOFA: 7,5 ± 3,7; Nutric Score modificada: 4,3 ± 2,01, e IMC medio: 27,2 ± 3,8). La principal causa de ingreso fue la sepsis (46,4 %). La duración de la estancia en UCI fue de 20,6 ± 15,1 días y el 39,3 % fallecieron durante la estancia en UCI. La nutrición enteral (82,1 %) fue más frecuente que la parenteral (17,9 %). Durante el seguimiento nutricional se realizaron 54 determinaciones analíticas específicas. La hiperglucemia fue la alteración metabólica más frecuente (83,3 % de las determinaciones). Las alteraciones electrolíticas fueron: hipocalcemia (50 %), hipofosfatemia (29,6 %) e hipopotasemia (27,8 %). Las alteraciones del perfil lipídico más frecuentes fueron la hipocolesterolemia (64,8 %) y la hipertrigliceridemia (27,8 %). Además, se modificó la prescripción nutricional en el 53,6 % de los pacientes: aumentar la dosis proteica (25 %), aumentar la dosis calórica (21,4 %) y cambiar a una dieta específica de órgano (17,8 %). Conclusión: en conclusión, la aplicación de la estrategia nutritrauma facilitó la detección de complicaciones metabólicas y la evaluación de la adecuada prescripción del TMN.
