Bioelectrical Impedance in Premature Newborns and Its Relationship with Diet Therapy in a Neonatal Intensive Care Unit.

(1) Background: To estimate resistance, reactance, and phase angle values among moderate preterm infants and their variation according to neonatal and maternal characteristics and nutritional intake. (2) Methods: This was a cohort that evaluated 43 moderate preterm infants using bioelectrical impedance analysis. The study variables included resistance, reactance, and phase angle measurements, in addition to classification of nutritional intake. (3) Results: Mean resistance was 602.0 ± 118.2 Ω, reactance was 57.2 Ω (IQR = 42.6-65.2), and phase angle was 522° (IQR = 4.1-6.6). Lower resistance values were found in the presence of risky pregnancy (532.2 ± 111.9 Ω vs. 650.9 ± 97.9 Ω, p < 0.001) and lower reactance values, in the presence of harmful maternal lifestyle habits at both the first (p = 0.01) and second assessments (p = 0.01). Eight preterm infants were considered to have insufficient nutritional intake (23.5%); 17, sufficient (50.0%) and 9, partially sufficient (26.5%). There was less reactance among preterm infants with insufficient nutritional intake (p < 0.001). (4) Conclusions: The bioelectrical impedance analysis measurements were within the range of values reported in other studies. There was an association between full diet and adequate nutritional intake with higher resistance values, while a lower reactance value was associated with the presence of risky pregnancy and harmful maternal lifestyle.

Microbiological contamination present in enteral tube feeding prepared in hospitals and/or at home: a systematic review.

CONTEXT: The safety of enteral formulas is important to restore and maintain the health of patients. OBJECTIVE: A systematic review of the literature was conducted to assess the microbiological contamination present in enteral tube feeding prepared in hospitals and/or at home. DATA SOURCES: A systematic search was conducted of the Medline, Scopus, BVS, CAPES/MEC, Embase, Science Direct, and SciELO databases and gray literature. DATA EXTRACTION: Eligible studies that analyzed the contamination of enteral formulas manipulated in hospitals and/or at home were selected; a quality assessment tool was used. DATA ANALYSIS: Twenty-three studies evaluated 1099 enteral formulations. Of these, 44.67% of enteral formulas (n = 491) exceeded the acceptable bacterial count. Samples of homemade enteral formulation preparations (86.03%; n = 191) had the highest bacterial counts, followed by mixed preparations (79.72%; n = 59), and commercial formulas (30.01%; n = 241). The number of samples of enteral formulations that exceeded the bacterial count at home was 70.79% (n = 160 at the hospital was 37.91% (n = 331). Total coliforms (82.68%; n = 406) and mesophilic aerobes (79.22%; n = 389) were the most common microorganisms. Samples with bacterial pathogens were also identified, with Bacillus cereus (4.07%; n = 20) and Listeria monocytogenes (3.66%; n = 18) being the most prevalent. CONCLUSIONS: A high number of samples of enteral formulations exceeded the bacterial count, but the risk to patient's health when consuming enteral tube feeding prepared in hospitals or at home may be low. This is because the bacteria present in the samples are not considered potential causes of disease but rather indicators of hygiene conditions.

Body composition and functional capacity in patients with Crohn's disease using Infliximab / Composição corporal e capacidade funcional de pacientes com doença de Crohn em uso de Infliximabe

Rationale: the use of anti-TNFα therapy, such as Infliximab (IFX), in patients with Chron's disease (CD) can lead to changes in body composition. Objective: to evaluate the body composition and functional capacity of patients with CD. Method: Cross-sectional study with patients with CD in clinical remission using IFX. For anthropometric evaluation, it was measured: weight, height and waist circumference; functional capacity by the hand grip strength test and body composition by bioelectric impedance. After that, the fat-free mass index and body fat index were calculated. Continouns variables were analyzed by Pearson or Spearman coefficient. For the multiple linear regression model, the time of use of IFX was used as a dependent variable and waist circumference, fat-free mass index, phase angle and handgrip strength were used as independent variables. Results: forty-three patients were evaluated, with an average of 43.1± 13.5 years of age. Of the total, 44.2% were overweight and 44.2% had increased waist circumference, 58.1% were classified with high to very high fat-free mass, 30.2% were below the adequacy parameter for fat-free mass index and 11.6% had reduced functional capacity. Conclusion: overweight, as well as increased waist circumference and body fat, is common in CD patients in clinical remission using Infliximab. Most patients had preserved functional capacity, however there wasn't association with time of use of IFX.

Introdução: o uso de terapia anti-TNFα, como o Infliximabe (IFX), em pacientes com doença de Chron (DC) pode levar a alterações na composição corporal. Objetivo: avaliar a composição corporal e capacidade funcional de pacientes com DC. Metodologia: estudo transversal com pacientes com DC em remissão clínica, em uso de IFX. Foi realizada avaliação antropométrica (peso, estatura e circunferência da cintura); avaliação de capacidade funcional (teste de força de pressão manual); e avaliação de composição corporal (impedância bioelétrica) com cálculo do índice de massa livre de gordura e índice de gordura corporal. Variáveis contínuas foram analisadas pelo coeficiente de correlação de Pearson ou Spearman. Para o modelo de regressão linear múltipla, o tempo de uso do IFX foi utilizado como variável dependente e circunferência da cintura, índice de massa magra, ângulo de fase e força de preensão manual foram utilizados como variáveis independentes. Resultados: foram avaliados 43 pacientes, com média de idade de 43,1± 13,5 anos. 44,2% estavam acima do peso e 44,2% possuíam circunferência da cintura aumentada, 58,1% foram classificados com índice de gordura corporal de alto a muito alto, 30,2% estavam abaixo do parâmetro de adequação para o índice de massa livre de gordura e 11,6% apresentaram capacidade funcional reduzida. Conclusão: o excesso de peso e o aumento de circunferência da cintura e gordura corporal é frequente em pacientes com DC em remissão clínica e em uso de IFX. A maioria dos pacientes apresentou capacidade funcional preservada, porém não houve associação com o tempo de uso do IFX.

Application of bioelectrical impedance in newborns: an integrative review / Aplicación de la impedancia bioeléctrica en recién nacidos: revisión integradora

Objective: the objective of this study was to identify the use of bioelectrical impedance in newborns (NB), as this is an easy-to-apply and non-invasive method of measurement that can be used for distinguishing fat-free mass (FFM), fat mass (FM), and total body water (TBW). Method: this was an integrative review of the literature using the PUBMED/MEDLINE, EMBASE, Web of Science, and Virtual Health Library databases to search for original articles between 2010-2020. A total of 900 articles were retrieved; after checking for duplicity and applying the eligibility criteria, 9 were further analyzed. Results: about the results, five studies used single frequency bioimpedance, with a specific population of neonates, preterm and/or full term, and different clinical conditions. Resistance was the most studied bioelectric indicator, the phase angle is little explored, and four studies investigated body composition (FFM, FM and TBW). Studies found that preterm newborns had lower amounts of TBW, FFM, and FM than term newborns, and there were differences in body composition between sex. The phase angle was lower for preterm newborns. Babies fed babies with high protein formulas had increases in the FFM. Conclusion: there is a need for multicenter studies to define standardized methods to be used with this public. (AU)

Objetivo: el objetivo de este estudio fue identificar el uso de la impedancia bioeléctrica en recién nacidos (NB), ya que ese método es de fácil medición y no invasivo para la distinción de masa libre de grasa (MLG), masa grasa (MG) y agua corporal total (ACT). Método: esta fue una revisión integradora de la literatura utilizando PubMed/MEDLINE, EMBASE, Web of Science y Virtual Health Library para la búsqueda de artículos originales (2010-2020). En total, se encontraron 900 artículos, aunque tras la verificación de duplicidad y aplicación delos criterios de elegibilidad, solo 9 fueron para análisis. Resultados: cinco estudios utilizaron el dispositivo de monofrecuencia. Cada investigación se aplicó en una población específica de neonatos, prematuros y/o a término y diferentes condiciones clínicas. La resistencia fue el indicador bioeléctrico más estudiado, el ángulo de fase fue poco explorado y cuatro estudios investigaron la composición corporal. Dos estudios encontraron que los recién nacidos prematuros tienen menos cantidades de ACT, MLG y MG que los RNT y se observó diferencia en la composición corporal entre los sexos. El ángulo de fase fue inferior en prematuros. Los lactantes que se alimentaron con una fórmula con mayor contenido proteico tenían una mayor cantidad de MLG. Conclusión: se observa la necesidad de estudios multicéntricos para definir métodos estandarizados para ser utilizados con este público. (AU)

Administration of enteral nutrition and gastrointestinal complications in Covid-19 critical patients in prone position.

Background: The prone position (PP) used in the treatment of critically ill patients infected with SARS-CoV-2, may be a barrier to enteral nutrition (EN). This study aimed to analyze the effectiveness and complications of EN in the PP, as well as clinical outcomes. Methods: Prospective cohort study with patients in EN and coronavirus disease 2019 (COVID-19), on mechanical ventilation (MV), which whom needed or not PP. Gastrointestinal intolerances (GII) related to PP were evaluated, and correlated with possible confounding factors. EN, days on MV, Intensive Care Unit (ICU) length of stay, hospital length of stay, ventilator-associated pneumonia (VAP) and mortality were analyzed. The data were evaluated daily and compared prone group (PG=57) and supine group (SG=69). Results: The PP was associated with GII (P=0.000) and presented in 32 patients (26,44%) with no difference among groups. Association between epinephrine (P=0.003), vasopressin (P=0.018), and GII was observed. There was no difference between the total volume of enteral nutrition (TVEN) infused in the groups. However, the mean EN infused for the days when the patient was on PP was (70.0% ± 31.5) and for the days in supine position was (74.8% ± 27.3), P= 0.006. The PG had a longer time on MV (P=0.005) and ICU (P=0.003) and PP was associated with VAP (P=<0.001). The infused TVEN showed no association with VAP (P=0.09). Conclusion: PP was a determining factor in GII and proved to be a risk factor for VAP, but the EN protocol seems to have ensured an adequate EN supply in PP and be a safe alternative.

Beau's line in COVID-19 after a long ICU stay / Línea de Beau en COVID-19 después de un tiempo largo de internación en UCI

The 2019 coronavirus disease pandemic (COVID-19) overloads hospitalizations in intensive care units (ICUs) around the world and its severe form is a complex disease that is still being understood. Due to the lack of direct evidence in patients with SARS-CoV-2 infection, guidelines for nutritional management have been based on evidence from critically ill patients in general. Thus, it is known that intense metabolic stress and malnutrition precede the appearance of Beau’s lines. This is the case report of a 58-year-old man with the severe form of COVID-19 hospitalized for 33 days in the ICU and who presented the Beau´s lines after 4 months of discharge, even with the infusion of nutritional therapy following the current recommendations for the critical period of the disease (AU)

Microbiological quality of enteral formulations handled at home: A systematic review.

BACKGROUND: Studies have shown an increase in the number of patients who use enteral nutrition at home and the benefits of this type of nutrition care. However, little is known about the risk of bacterial contamination of enteral formulations prepared at home. Therefore, the aim of the study was to assess the microbiological quality of home-prepared enteral formulations. METHODS: This study is a systematic review, registered in PROSPERO. The search for articles was carried out in databases and gray literature. Eligible studies that microbiologically analyzed homemade enteral preparations (HEPs), blended enteral preparations (BEPs), and commercial enteral formulas (CEFs) that were prepared at home were selected. The types and quantities of microorganisms, sources of contamination in the handling area, and the consequences of contamination (signs and symptoms) were the subjects extracted from the studies. RESULTS: Five studies evaluated 217 enteral formulations. It was found that 72.81% of the enteral formulations exceeded the acceptable bacterial count in the case of at least one of the analyzed microorganisms. This result corresponded to 93.58% (n = 73) of the HEPs, 81.96% (n = 50) of the BEPs, and 44.87% (n = 35) of the CEFs. The presence of 10 different microorganisms was identified in the enteral formulations, and total coliforms and mesophilic aerobics were the microorganisms found in the greatest quantity in the samples. CONCLUSION: The three types of home-prepared enteral formulations showed unsatisfactory microbiological quality, indicating poor hygiene conditions during food handling.

Nutrition assistance improves skeletal muscle function and performance in community-dwelling older women / Assistência nutricional melhora o desempenho muscular esquelético de mulheres idosas residentes na comunidade

To analyze the effects of nutritional assistance focusing on protein intake (in the individual's usual diet) in relation to muscle mass, and the muscle strength and functional performance of community-dwelling older women. Methods: This is a non-randomized controlled clinical trial. Forty-three community-dwelling older women, who were allocated to the Control Group (CG; n = 20) or the Nutrition Group (NG; n = 23). The NG received individualized nutrition assistance and participated in group activities that focused on dietary protein intake once a week for 12 weeks. Main outcome measures: protein and energy intake; handgrip strength (HGS); gait speed (GS); quadriceps cross-sectional area (CSA); and intramuscular non-contractile tissue (IMNCT). The Student's t-test for independent samples, the Mann-Whitney U test, and a mixed model ANOVA with two factors (group and time) were adopted, followed by a post hoc Bonferroni test. A Spearman's correlation test was performed on tests for HGS; GS; CSA; IMNCT; age; and protein intake adjusted for weight (g/kg) (p ≤ 0.050). Results: Participants in the NG showed higher CSA values than those in the CG (p < 0.001). NG participants also had higher HGS (p < 0.001) and GS (p = 0.037) when compared to pre-intervention. Correlations were observed between IMNCT and protein intake adjusted for weight (g/kg) (r = -0.517; p = 0.020); HGS, and CSA (r = 0.827; p = 0.000); and CSA and age (r = -0.520, p = 0.009).

Métodos: Trata-se um ensaio clínico controlado não randomizado. Quarenta e três idosas da comunidade foram alocadas no Grupo Controle (GC; n = 20) ou no Grupo Nutrição (GN; n = 23). O GN recebeu atendimento nutricional individualizado e participou de atividades grupais com foco na ingestão proteica da dieta uma vez por semana, durante 12 semanas. Principais medidas de resultado: ingestão de proteína e energia; força de preensão palmar (FPP); teste de velocidade da marcha (TVM); área de secção transversa do quadríceps (ASTq); e tecido intramuscular não contrátil (TIMNC). Utilizou-se o teste t de Student para amostras independentes, o teste U de Mann-Whitney e um modelo misto de análise de variância (ANOVA) com dois fatores (grupo e tempo), seguido de teste post hoc de Bonferroni. Um teste de correlação de Spearman foi realizado para FPP; TVM; ASTq; TIMNC; idade; e ingestão proteica ajustada para peso (g/kg) (p ≤ 0,050). Resultados: Os participantes do GN apresentaram valores de ASTq superiores aos do GC (p < 0,001). Os participantes do GN também exibiram maior FPP (p < 0,001) e GS (p = 0,037) quando comparados à pré-intervenção. Foram observadas correlações entre TIMNC e ingestão proteica ajustada para peso (g/kg) (r = -0,517; p = 0,020); HGS e ASTq (r = 0,827; p = 0,000); e ASTq e idade (r = -0,520, p = 0,009).

HOW IS THE DIET QUALITY OF PATIENTS WITH CROHN'S DISEASE IN CLINICAL REMISSION USING INFLIXIMAB?

BACKGROUND: A healthy diet is recommended for patients with Crohn's disease (CD) in remission. OBJECTIVE: To evaluate the diet quality of patients with CD. METHODS: Cross-sectional study with patients with CD and clinical remission using the biological agent infliximab. The diet quality was assessed using the Diet Quality Index-Revised (DQI-R). DQI-R was calculated based on 24-hour dietary recalls (24HR), being classified as "inadequate diet" (≤40 points), "diet requiring modifications" (41 to 64 points) and "healthy diet" (≥65 points). Weight, height and waist circumference (WC) of patients were assessed. For comparison between groups, Student's t-test or Mann-Whitney was used. For correlation between continuous variables, Pearson or Spearman coefficient was used. Values of P<0.05 indicated statistical significance. RESULTS: A total of 43 patients participated in the study. The final DQI-R score was 49.1 points - "diet requiring modifications". No patient received the classification of "healthy diet" (maximum score =59.7), 55.8% presented "diet requiring modifications" and 44.2% "inadequate diet". When comparing the "inadequate diet" and "diet requiring modifications" groups, a lower mean age was observed in the "inadequate diet" group (37.6±14.8 versus 47.4±10.5 y, P=0.02). It was found that 44.2% of the patients were overweight (body mass index [BMI] ≥25 kg/m²) and had increased WC (women: WC ≥80 cm and men: WC ≥94 cm). A positive correlation was found between the final DQI-R score and BMI (P=0.046; r=0.346). CONCLUSION: Patients with CD in clinical remission using infliximab are not adopting a diet considered healthy, which points to the need for an individualized nutritional approach.

Effects of Exergames and Protein Supplementation on Body Composition and Musculoskeletal Function of Prefrail Community-Dwelling Older Women: A Randomized, Controlled Clinical Trial.

This study aimed to investigate the effects of exergames and protein supplementation on the body composition and musculoskeletal function of pre-frail older women. Methods: A randomized controlled clinical trial was conducted with 90 pre-frail older women (71.2 ± 4.5 years old) divided into five groups: control (CG); exergames training (ETG); protein supplementation (PSG); exergames combined with protein supplementation (ETPSG); exergames combined with isoenergetic supplementation (ETISG). The primary outcomes were pre-frailty status, body composition (appendicular muscle mass (ASM); appendicular muscle mass index (ASMI)) assessed by dual energy X-ray absorptiometry and gastrocnemius muscle architecture via ultrasound. Secondary outcomes were protein intake, plasma levels of interleukin (IL)-6, plantar and dorsiflexion isokinetic peak torque, and handgrip strength (HS). Data were analyzed using an ANOVA mixed model test and Bonferroni post hoc test (p < 0.05). The ETG showed a reduction of ASM (16.7 ± 3.4 vs. 16.1 ± 3.3 kg; Δ = -0.5; p = 0.02; d = 0.26) and ASMI (6.8 ± 0.9 vs. 6.5 ± 0.9 kg; Δ = -0.2; p = 0.03; d = 0.35), without changing ASM in other groups. The average protein intake in the supplemented groups (PSG and ETPSG) was 1.1 ± 0.2 g/kg/day. The dorsiflexion peak torque increased 11.4% in ETPSG (16.3 ± 2.5 vs. 18.4 ± 4.2 Nm; p = 0.021; d = -0.58). The HS increased by 13.7% in ETG (20.1 ± 7.2 vs. 23.3 ± 6.2 kg, Δ = 3.2 ± 4.9, p = 0.004, d = -0.48). The fatigue/exhaustion reduced by 100% in ETG, 75% in PSG, and 100% in ETPSG. Physical training with exergames associated with protein supplementation reversed pre-frailty status, improved the ankle dorsiflexors torque, and ameliorated fatigue/exhaustion in pre-frail older women.

RESUMO CONTEXTO: É recomendado alimentação saudável para pacientes com doença de Crohn (DC) em remissão. OBJETIVO: Avaliar a qualidade da dieta de pacientes com DC. MÉTODOS: Estudo transversal com pacientes com DC em remissão clínica e em uso do imunobiológico infliximabe. A qualidade da dieta foi avaliada pelo índice de qualidade da dieta revisado (IQD-R). O IQD-R foi calculado a partir do recordatório 24 horas, sendo classificado em "dieta inadequada" (≤40 pontos), "dieta que requer modificações" (41 a 64 pontos) e "dieta saudável" (≥65 pontos). Os pacientes foram avaliados quanto ao peso, altura e circunferência da cintura (CC). Para comparação entre grupos foi utilizado o test-t de Student ou Mann-Whitney. Para correlação entre variáveis contínuas foi utilizado o coeficiente de Pearson ou Spearman. Valores de P<0,05 indicaram significância estatística. RESULTADOS: Participaram do estudo 43 pacientes. A pontuação final do IQD-R foi de 49,1 pontos - "dieta que requer modificações". Nenhum paciente recebeu a classificação de "dieta saudável" (pontuação máxima =59,7), 55,8% apresentaram "dieta que requer modificações" e 44,2% "dieta inadequada". Ao comparar os grupos "dieta inadequada" e "dieta que requer modificações", foi observado menor média de idade no grupo "dieta inadequada" (37,6±14,8 versus 47,4±10,5 anos, P=0,02). Verificou-se que 44,2% dos pacientes estavam acima do peso (índice de massa corporal (IMC) ≥25 kg/m²) e possuíam CC aumentada (mulheres: CC ≥80 cm e homens: CC ≥94 cm). Foi encontrada correlação positiva entre a pontuação final do IQD-R e o IMC (P=0,046; r=0,346). CONCLUSÃO: Os pacientes com DC em remissão clínica e em uso de infliximabe não estão adotando dieta com qualidade considerada saudável o que aponta a necessidade de abordagem nutricional individualizada.

Consensus on the standard terminology used in the nutrition care of adult patients with chronic kidney disease / Consenso sobre a terminologia padronizada do processo de cuidado em nutrição para pacientes adultos com doença renal crônica

Abstract This nutrition consensus document is the first to coordinate the efforts of three professional organizations - the Brazilian Association of Nutrition (Asbran), the Brazilian Society of Nephrology (SBN), and the Brazilian Society of Parenteral and Enteral Nutrition (Braspen/SBNPE) - to select terminology and international standardized tools used in nutrition care. Its purpose is to improve the training delivered to nutritionists working with adult patients with chronic kidney disease (CKD). Eleven questions were developed concerning patient screening, care, and nutrition outcome management. The recommendations set out in this document were developed based on international guidelines and papers published in electronic databases such as PubMed, EMBASE(tm), CINHAL, Web of Science, and Cochrane. From a list of internationally standardized terms, twenty nutritionists selected the ones they deemed relevant in clinical practice involving outpatients with CKD. The content validity index (CVI) was calculated with 80% agreement in the answers. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) framework was used to assess the strength of evidence and recommendations. A total of 107 terms related to Nutrition Assessment and Reassessment, 28 to Diagnosis, nine to Intervention, and 94 to Monitoring and Evaluation were selected. The list of selected terms and identified tools will be used in the development of training programs and the implementation of standardized nutrition terminology for nutritionists working with patients with chronic kidney disease in Brazil.

Resumo Este consenso representa a primeira colaboração entre três organizações profissionais com foco em nutrição: Associação Brasileira de Nutrição (Asbran), Sociedade Brasileira de Nefrologia (SBN) e Sociedade Brasileira de Nutrição Parenteral e Enteral (Braspen/SBNPE), com o objetivo de identificar a terminologia e instrumentos padronizados internacionalmente para o processo de cuidado em nutrição. O foco é facilitar a condução de treinamentos de nutricionistas que trabalham com pacientes adultos com doenças renais crônicas (DRC). Foram levantadas onze questões relacionadas à triagem, ao processo de cuidado e à gestão de resultados em nutrição. As recomendações foram baseadas em diretrizes internacionais e em bancos de dados eletrônicos, como PubMed, EMBASE(tm), CINHAL, Web of Science e Cochrane.

Consensus on the standard terminology used in the nutrition care of adult patients with chronic kidney disease.

This nutrition consensus document is the first to coordinate the efforts of three professional organizations - the Brazilian Association of Nutrition (Asbran), the Brazilian Society of Nephrology (SBN), and the Brazilian Society of Parenteral and Enteral Nutrition (Braspen/SBNPE) - to select terminology and international standardized tools used in nutrition care. Its purpose is to improve the training delivered to nutritionists working with adult patients with chronic kidney disease (CKD). Eleven questions were developed concerning patient screening, care, and nutrition outcome management. The recommendations set out in this document were developed based on international guidelines and papers published in electronic databases such as PubMed, EMBASE(tm), CINHAL, Web of Science, and Cochrane. From a list of internationally standardized terms, twenty nutritionists selected the ones they deemed relevant in clinical practice involving outpatients with CKD. The content validity index (CVI) was calculated with 80% agreement in the answers. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) framework was used to assess the strength of evidence and recommendations. A total of 107 terms related to Nutrition Assessment and Reassessment, 28 to Diagnosis, nine to Intervention, and 94 to Monitoring and Evaluation were selected. The list of selected terms and identified tools will be used in the development of training programs and the implementation of standardized nutrition terminology for nutritionists working with patients with chronic kidney disease in Brazil.

GLIM criteria for malnutrition diagnosis of hospitalized patients presents satisfactory criterion validity: A prospective cohort study.

BACKGROUND & AIMS: Malnutrition is prevalent among hospitalized patients, but there is no universally accepted consensus regarding its diagnosis. Recently, the Global Leadership Initiative on Malnutrition (GLIM) proposed a new framework for the malnutrition diagnosis and until this moment there is scarce evidence regarding its validity. This study aimed to evaluate the concurrent and predictive validity of GLIM criteria for malnutrition diagnosis in hospitalized patients. METHODS: Prospective cohort study involving adult/elderly hospitalized patients. The malnutrition diagnoses according to Subjective Global Assessment (SGA) and GLIM criteria were performed within 48 h of admission. Patients were followed up until hospital discharge to assess the length of hospital stay (LOS) and in-hospital mortality. Six months post discharge; the patients were contacted to collect the outcomes readmission and death. Agreement and accuracy tests, Cox and Logistic regression analysis were performed for testing criterion validity. RESULTS: 601 patients (55.7 ± 14.8 years, 51.3% men) were evaluated. Malnutrition was diagnosed in 33.9% and 41.6% of patients, by SGA and GLIM criteria, respectively. GLIM criteria presented a satisfactory accuracy, (AUC = 0.842; CI95% 0.807-0.877) with a sensitivity of 86.6%, and a specificity of 81.6%. The presence of malnutrition by GLIM criteria increased the chance of prolonged hospitalization by 1.76 (CI95% 1.23-2.52) times, and the risk of in-hospital deaths by 5.1 (CI95% 1.14-23.14) times. It was also associated with death within six months (RR = 3.96, CI95% 1.49-10.53). CONCLUSION: GLIM criteria for malnutrition diagnosis presented satisfactory criterion validity and should be applied during clinical practice.

Concurrent and Predictive Validity of AND-ASPEN Malnutrition Consensus Is Satisfactory in Hospitalized Patients: A Longitudinal Study.

BACKGROUND: Subjective Global Assessment (SGA) is the reference method to identify hospital malnutrition. The Academy of Nutrition and Dietetics and American Society for Parenteral and Enteral Nutrition (AND-ASPEN) proposed a more objective consensus, but studies regarding its validity are still scarce. This study aimed to evaluate the concurrent and predictive validity of the AND-ASPEN Consensus. METHODS: Prospective cohort conducted with hospitalized adult and elderly patients. At admission, general data were collected and patients were evaluated by SGA and AND-ASPEN with and without handgrip strength (HGS) for nutrition diagnoses. Patients were followed up for collection of outcomes-length of hospital stay (LOS), in-hospital death, readmission, and mortality within 6 months after being discharged. Concurrent and predictive validity were tested. RESULTS: Six hundred patients (55.7 ± 14.8 years, 51.3% males) were evaluated. The median of LOS was 10.0 (5.018.0) days and in-hospital mortality was 2.7%. SGA identified 34.0% and AND-ASPEN 34.6% of patients as malnourished. AND-ASPEN had substantial agreement with SGA (κ = 0.690) and satisfactory accuracy (AUC = 0.85; 95% CI, 0.810.88). Malnutrition defined by AND-ASPEN predicted about 1.4 times higher risk of prolonged LOS (95% CI, 1.2-1.6) and hospital readmission (95% CI, 1.2-1.8), besides 5.0 times higher risk of hospital death (95% CI, 1.3-18.8) and 6 months' death (95% CI, 2.6-9.9), in an adjusted analysis. The validity of AND-ASPEN without HGS was also satisfactory. CONCLUSION: AND-ASPEN can be used for malnutrition diagnoses, even without HGS because it has satisfactory concurrent and predictive validity.

Can oral nutritional supplements increase energy and protein intake among hospitalized patients? / ¿Los suplementos nutricionales orales pueden aumentar la energía y la proteína en pacientes hospitalizados?

ABSTRACT Background: Oral nutritional supplements aim at offsetting dietary deficits and helping to meet energy and protein targets. Due to the absence of data about their role in food intake, it is necessary to evaluate the contribution of these products to the estimated needs of hospitalized patients. Methods: This is a prospective longitudinal study with hospitalized patients over 18 years of age, admitted to a public university hospital, who were given oral nutritional supplements, according to clinical guidelines. Food intake was quantified throughout the period such products were prescribed. Results: 805-day food intake follow-up and record of 128 patients, who took supplements for 6.4 days on average. The use of nutritional supplements demonstrated a significant contribution to the input of both energy (1576 kcal/day versus 1263 kcal/day, p<0.001) and protein (68.7 g/day versus 50.3 g/day, p<0.001). Conclusions: Nutritional supplements help increase food intake and achieve nutritional goals when prescribed in a hospital setting.

RESUMEN Antecedentes: los suplementos nutricionales orales tienen como objetivo compensar los déficits dietéticos y ayudar a cumplir los objetivos de energía y proteínas. Debido a la ausencia de datos sobre su papel en la ingesta de alimentos, es necesario evaluar la contribución de estos productos a las necesidades estimadas de los pacientes hospitalizados. Métodos: Este es un estudio longitudinal prospectivo con pacientes hospitalizados mayores de 18 años, ingresados en un hospital universitario público, que recibieron suplementos nutricionales orales, según la derivación clínica. La ingesta de alimentos se cuantificó durante todo el período en que se prescribieron dichos productos. Resultados: seguimiento de la ingesta alimentaria de 805 días y registro de 128 pacientes, que tomaron suplementos durante 6,4 días en promedio. El uso de suplementos nutricionales demostró una contribución significativa al aporte de energía (1576 kcal/día versus 1263 kcal/día, p< 0,001) y proteína (68,7 g/día versus 50,3 g/día, p<0,001). Conclusiones: los suplementos nutricionales ayudan a aumentar la ingesta de alimentos y alcanzar objetivos nutricionales cuando se prescriben en un entorno hospitalario.
