Qualidade dos dados antropométricos de crianças menores de cinco anos em sistemas de informação no estado de São Paulo, Brasil / The quality of the anthropometric data on children under five years of age in information systems in the State of São Paulo, Brazil

Resumo O objetivo foi analisar a qualidade dos dados antropométricos de crianças menores de cinco anos em dois sistemas de informação no estado de São Paulo. A amostra compreendeu 2.117.108 crianças do Sistema de Vigilância Alimentar e Nutricional (Sisvan) e 748.551 do Projeto Estadual do Leite (Vivaleite). Inicialmente, avaliamos a frequência de valores faltantes e fora do espectro do equipamento, e calculamos o índice de preferência de dígito para peso. Após calcular os índices de altura para idade (A-I), peso para idade (P-I) e índice de massa corporal para idade (IMC-I), identificamos os valores biologicamente implausíveis (VBI) e calculamos o desvio-padrão (DP). Para cada município, calculamos a média e o DP de A-I, P-I e IMC-I; e plotamos os valores de DP em função da média. A preferência de dígito no peso foi maior em crianças de 24 a 59 meses no Sisvan. A frequência de VBI para A-I (SISVAN 2,56%; Vivaleite 0,98%) foi maior do que para P-I (Sisvan 2,10%; Vivaleite 0,18%). Para o índice A-I as variações entre os municípios foram mais acentuadas no Vivaleite do que no Sisvan. A variável altura apresentou baixa confiabilidade nos dois sistemas. A variável peso apresentou qualidade satisfatória no Vivaleite e insatisfatória no Sisvan.

Abstract This paper involves the analysis of the quality of anthropometric data on children under five years of age in two information systems in the State of São Paulo. The sample included 2,117,108 children from the Food and Nutrition Surveillance System (SISVAN), and 748,551 from the State Milk Project (VIVALEITE). Initially, we evaluated the frequency of missing values and others outside the equipment spectrum and calculated the digit-to-weight preference index. After calculating height-for-age (HAZ), weight-for-age (WAZ), and body mass index-for-age (BAZ), we flagged the biologically implausible values (BIV) and calculated the standard deviation (SD). For each municipality, we calculated the mean and the SD of HAZ, WAZ, and BAZ; and plotted the SD values as a function of the mean. The digit-to-weight preference index was greater among children aged between 24 and 59 months in SISVAN. The frequency of BIV for HAZ (SISVAN 2.56%; VIVALEITE 0.98%) was higher than for WAZ (SISVAN 2.10%; VIVALEITE 0.18%). For HAZ, variations among municipalities were more pronounced in VIVALEITE than in SISVAN. The height variable presents low reliability in both systems. The weight variable reveals satisfactory quality in VIVALEITE and unsatisfactory quality in SISVAN.

An evidence-based tuberculosis patient’s nutrition assessment tool and intervention guidelines for DOTS providers: a modified Delphi study

Background: An individual's nutritional state is an indicator of their overall health. Poor nutrition, under nutrition, vitamin deficiency and protein energy malnutrition a form of nutritional problems. In low and middle-income countries, the linkage between infectious diseases such as tuberculosis and under nutrition is critical to public health. Thus, the current study aims to explore the DOTS Providers' concerns and develop evidence-based tuberculosis patient’s nutrition assessment tool and intervention guidelines for DOTS providers, which can be quick and easy to assess. Methods: A modified Delphi process was used to develop the nutrition assessment tool and intervention guidelines through mixed-method approach. Three rounds of the Delphi process were carried out via email, with a letter requesting to participate in the Delphi process. Result: An in-depth interview schedule was conducted to extract themes and subthemes generating an item pool in the initial phase. The main themes identified were Perception of disease, TB cure, Association of under nutrition and TB management, Problems or difficulties encountered, Counsel, Assessment and intervention. Quantitative data analysis was performed manually by calculating the content validity index (CVI). The CVI was found to be >80% for all the items with I-CVI?0.8 and S-CVI?0.9. All the items were considered very essential with a score of 1. Conclusions: The assessment tool should be subjected to other levels of evaluation that measures the suitability of the tool and interventional guidelines for the intended field.

Predictive value of controlling nutritional status score in the prognosis of patients with advanced diffuse large B-cell lymphoma / 白血病·淋巴瘤

Objective:To investigate the predictive value of controlling nutritional status (CONUT) score in the prognosis of patients with advanced diffuse large B-cell lymphoma (DLBCL).Methods:A retrospective case series study was performed. The clinical data of 654 patients newly diagnosed with advanced DLBCL diagnosed in 7 medical centers in Huaihai Lymphoma Working Group from October 2009 to January 2022 were retrospectively collected. All the patients received rituximab-based immune chemotherapy regimens. The patients were randomly assigned to the training set (458 cases) and the validation set (196 cases) in a 7:3 ratio. The clinicopathological data of patients were collected, and the CONUT score was calculated based on albumin, lymphocyte count, and total cholesterol. The optimal critical value of CONUT scote was determined by using MaxStat method. Kaplan-Meier method was used to draw survival curves; Cox proportional hazards model was used to make univariate analysis and multivariate analysis on the factors influencing overall survival (OS). The efficacy of CONUT score in combination with the International prognostic index (IPI) and an enhanced IPI (NCCN-IPI) in predicting OS was evaluated by using receiver operating characteristic (ROC) curves.Results:The median follow-up time of 654 patients was 38.1 months (95% CI: 35.3 months- 40.9 months), and the 5-year OS rate was 49.2%. According to the MaxStat method, the optimal critical value for CONUT score was determined to be 6 points. All the patients were classified into the normal nutritional status group (CONUT score ≤ 6 points, 489 cases) and the poor nutritional status group (CONUT score > 6 points, 165 cases). The results of the multivariate analysis showed that CONUT score > 6 points, male, lactate dehydrogenase >240 U/L, high white blood cell count, low hemoglobin level and age > 60 years were independent risk factors for OS of patients with advanced DLBCL (all P < 0.05). Patients in the poor nutritional status group (CONUT score > 6 points) had worse OS compared with that in the normal nutritional status group in the overall cohort of advanced DLBCL. Subgroup analysis revealed that among patients with Eastern Cooperative Oncology Group-performance status (ECOG PS) score < 2 points, IPI low-intermediate risk, IPI intermediate-high risk, NCCN-IPI low-intermediate risk, and NCCN-IPI intermediate-high risk, the patients in the poor nutritional status group (CONUT score > 6 points) had worse OS compared with that in the normal nutritional status group (CONUT score ≤ 6 points) (all P < 0.05). Conclusions:CONUT score has a certain value in the assessment of the prognosis of patients with advanced DLBCL, and its predictive efficacy is further improved when combined with IPI and NCCN-IPI.

The application value of radiomics in the nutritional therapy of surgical patients / 中华普通外科杂志

The incidence of malnutrition in surgical patients is high and affects the clinical outcome of patients. Through the extraction and analysis of image data, radiomics can assess changes in the composition of the body, such as skeletal muscle and fat, and it demonstrates tremendous potential in nutritional screening, assessment, diagnosis, and evaluation of treatment effects, emerging as a crucial evaluation tool in nutritional therapy for surgical patients. Furthermore, radiomics can predict patients' clinical outcomes, providing more precise treatment plans. Therefore, the application of radiomics should be fully emphasized in nutritional therapy for surgical patients to promote their enhanced recovery. With the continuous development and improvement of radiomics technology in the future, its application in nutritional therapy for surgical patients is expected to become more extensive and profound, bringing better treatment outcomes and quality of life to patients.

O Índice Nutricional Prognóstico está Associado ao Grau de Circulação Colateral Coronariana em Pacientes com Angina Estável e Oclusão Total Crônica / Prognostic Nutritional Index is Associated with the Degree of Coronary Collateral Circulation in Stable Angina Patients with Chronic Total Occlusion

Resumo Fundamento: A circulação colateral coronária (CCC) pode efetivamente melhorar o suprimento sanguíneo miocárdico para a área de OCT (oclusão coronariana total crônica) e pode, assim, melhorar o prognóstico de pacientes com síndrome coronariana estável (SCE). O grau de inflamação e alguns marcadores de inflamação foram associados ao desenvolvimento de colaterais. Objetivo: Investigar se o índice nutricional prognóstico (INP) tem associação com o desenvolvimento de CCC em pacientes com SCE. Métodos: Um total de 400 pacientes com SCE com presença de OTC em pelo menos uma importante artéria coronária epicárdica foi incluído neste estudo. Os pacientes foram divididos em dois grupos de acordo com o escore Rentrop. Escores de 0 a 1 foram considerados CCC pouco desenvolvidas e escores de 2 a 3 foram aceitos como CCC bem desenvolvidas. A significância estatística foi definida como um valor p < 0,05 para todas as análises. Resultados: A média de idade da coorte do estudo foi de 63±10 anos; 273 (68,3%) eram do sexo masculino. O grupo CCC pouco desenvolvido apresentou um nível de INP significativamente mais baixo em comparação com o grupo CCC bem desenvolvido (38,29±5,58 vs 41,23±3,85, p<0,001). Na análise multivariada, o INP (odds ratio 0,870; intervalo de confiança de 95% 0,822-0,922; p<0,001) foi um preditor independente de CCC pouco desenvolvida. Conclusão: O INP pode ser utilizado como um dos preditores independentes da formação do CCC. Foi positivamente associado ao desenvolvimento de colaterais coronárias em pacientes com SCE com OTC.

Abstract Background: Coronary collateral circulation (CCC) can effectively improve myocardial blood supply to the area of CTO (chronic total coronary occlusion) and can, thus, improve the prognosis of patients with stable coronary syndrome (SCS). The degree of inflammation and some inflammation markers were associated with the development of collaterals. Objective: To investigate whether prognostic nutritional index (PNI) has an association with the development of CCC in patients with SCS. Methods: A total of 400 SCS patients with the presence of CTO in at least one major epicardial coronary artery were included in this study. The patients were divided into two groups according to the Rentrop score. Scores of 0 to 1 were considered poor developed CCC, and scores of 2 to 3 were accepted as good developed CCC. Statistical significance was set as a p-value < 0.05 for all analyses. Results: The mean age of the study cohort was 63±10 years; 273 (68.3%) were males. The poor-developed CCC group had a significantly lower PNI level compared with the good-developed CCC group (38.29±5.58 vs 41.23±3.85, p< 0.001). In the multivariate analysis, the PNI (odds ratio 0.870; 95% confidence interval 0.822-0.922; p< 0.001) was an independent predictor of poorly developed CCC. Conclusion: The PNI can be used as one of the independent predictors of CCC formation. It was positively associated with the development of coronary collaterals in SCS patients with CTO.

Effects of Preoperative Nutritional Status and Lymphocyte Count on the Development of Early-term Atrial Fibrillation After Coronary Artery Bypass Grafting: A Retrospective Study

ABSTRACT Introduction: Although there are publications in the literature stating that parameters related to the nutritional status of patients are associated with the clinical outcomes of those with coronary artery disease, it is also stated that there is insufficient data on the relationship between nutritional indices and long-term outcomes and major adverse cardiovascular events in patients undergoing isolated coronary artery bypass grafting. Methods: This retrospective study was conducted with patients who underwent isolated elective on-pump coronary artery bypass grafting in our hospital. Patients who underwent emergency coronary artery bypass grafting or those with known atrial fibrillation in the preoperative period were excluded. Patients were analyzed and compared in two groups according to the development of postoperative atrial fibrillation. Results: The data of 93 coronary artery bypass grafting patients (71 [76%] males) with a mean age of 62.86 ± 9.53 years included in the study were evaluated. Both groups had similar preoperative ejection fraction value, hemoglobin level, age, number of distal bypasses, and postoperative mortality rates. Although the mean cardiopulmonary bypass and aortic cross-clamping times were higher in Group 1, they were not statistically significant. In our study, the mean prognostic nutrition index value was 51.76 ± 3002. Conclusion: According to our study results, there was no statistically significant difference between prognostic nutrition index values and the development of atrial fibrillation after coronary artery bypass grafting, which is similar to some publications in the literature. We think that it would be beneficial to conduct randomized studies involving more patients on this subject.

O valor do índice nutricional prognóstico pré-operatório no câncer gástrico após ressecção curativa / The value of preoperative prognostic nutritional index in gastric cancer after curative resection

ABSTRACT BACKGROUND: Predicting short- and long-term outcomes of oncological therapies is crucial for developing effective treatment strategies. Malnutrition and the host immune status significantly affect outcomes in major surgeries. AIMS: To assess the value of preoperative prognostic nutritional index (PNI) in predicting outcomes in gastric cancer patients. METHODS: A retrospective cohort analysis was conducted on patients undergoing curative-intent surgery for gastric adenocarcinoma between 2009 and 2020. PNI was calculated as follows: PNI=(10 x albumin [g/dL])+(0.005 x lymphocytes [nº/mm3]). The optimal cutoff value was determined by the receiver operating characteristic curve (PNI cutoff=52), and patients were grouped into low and high PNI. RESULTS: Of the 529 patients included, 315 (59.5%) were classified as a low-PNI group (PNI<52) and 214 (40.5%) as a high-PNI group (PNI≥52). Older age (p=0.050), male sex (p=0.003), American Society of Anesthesiologists score (ASA) III/IV (p=0.001), lower hemoglobin level (p<0.001), lower body mass index (p=0.001), higher neutrophil-lymphocyte ratio (p<0.001), D1 lymphadenectomy, advanced pT stage, pN+ and more advanced pTNM stage were related to low-PNI patient. Furthermore, 30-day (1.4 vs. 4.8%; p=0.036) and 90-day (3.3 vs. 10.5%; p=0.002) mortality rates were higher in low-PNI compared to high-PNI group. Disease-free and overall survival were worse in low-PNI patients compared to high-PNI (p<0.001 for both). ASA III/IV score, low-PNI, pT3/T4, and pN+ were independent risk factors for worse survival. CONCLUSIONS: Preoperative PNI can predict short- and long-term outcomes of patients with gastric cancer after curative gastrectomy. Low PNI is an independent factor related to worse disease-free and overall survival.

RESUMO RACIONAL: Estimar os desfechos de curto e longo prazo das terapias contra o câncer é crucial para o desenvolvimento de estratégias de tratamento eficazes. A desnutrição e o estado imunológico do hospedeiro afetam significativamente os desfechos em cirurgias de grande porte. OBJETIVOS: Avaliar o valor do índice nutricional prognóstico pré-operatório (INP) na predição de desfechos em pacientes com câncer gástrico. MÉTODOS: Foi realizada uma análise de coorte retrospectiva de pacientes submetidos à cirurgia com intenção curativa para adenocarcinoma gástrico entre 2009 e 2020. O INP foi calculado da seguinte forma: INP=(10 x albumina [g/dL])+(0.005 x linfócitos [nº/mm3]). O valor de corte ideal foi determinado pela curva característica de operação do receptor (ponto de corte do INP=52), e os pacientes foram agrupados em INP baixo ou alto. RESULTADOS: Dos 529 pacientes incluídos, 315 (59,5%) foram classificados como grupo de baixo INP (INP<52) e 214 (40,5%) como grupo de alto INP (INP>52). Idade mais avançada (p=0,050), sexo masculino (p=0,003), escore da Sociedade Americana de Anestesiologistas (ASA) III/IV (p=0,001), menor nível de hemoglobina (p<0,001), menor índice de massa corpórea (p=0,001), maior relação neutrófilos-linfócitos (p<0,001), linfadenectomia D1, estágio pT avançado, pN+ e estágio pTNM mais avançado foram relacionados ao paciente com baixo INP. Além disso, as taxas de mortalidade em 30 dias (1,4 vs. 4,8%; p=0,036) e em 90 dias (3,3 vs. 10,5%; p=0,002) foram maiores no grupo com baixo PNI em comparação ao grupo com alto INP. A sobrevida livre de doença e a sobrevida global foram piores em pacientes com baixo INP em comparação com pacientes com alto INP (p<0,001 para ambos). Escore ASA III/IV, baixo INP, pT3/T4 e pN+ foram fatores de risco independentes para pior sobrevida. CONCLUSÕES: O INP pré-operatório pode predizer desfechos de curto e longo prazo de pacientes com câncer gástrico após gastrectomia curativa. Baixo INP é um fator independente relacionado a piores sobrevida livre de doença e sobrevida global.

Impact of pretransplantation malnutrition risk on the clinical outcome and graft survival of kidney transplant patients / Impacto do risco de desnutrição pré-transplante no desfecho clínico e na sobrevida do enxerto de pacientes transplantados renais

ABSTRACT Background: The prevalence of malnourished patients before transplantation and the influence of malnutrition on graft and patient outcomes remain underestimated, despite being associated with higher postoperative morbidity and mortality. This study aimed to develop an easy nutritional screening tool and evaluate the impact of nutritional status on clinical outcome, graft survival (GS) and mortality risk in kidney transplant patients (KTP). Methods: In this retrospective cohort study including 451 KTP, we developed a score by using anthropometric, clinical, and laboratory measures performed in the pretransplant evaluation. The patients were stratified into 3 groups according to the final score: G1 (0 or 1 point)=low risk, G2 (2 to 4 points)=moderate risk, and G3 (>5 points)=high risk of malnutrition. The patients were monitored after transplantation at least 1 to 10 years. Results: Stratifying the 451 patients based on the pretransplant risk score, G1, G2, and G3 were composed of 90, 292, and 69 patients, respectively. Patients from G1 maintained the lowest serum creatinine levels at hospital discharge when compared with others (p = 0.012). The incidence of infection in the patients from G3 was higher than patients from G1 and G2 (p = 0.030). G3 recipients showed worse GS than G1 patients (p = 0.044). G3 patients showed almost threefold higher risk for graft loss (HR 2.94, 95% CI 1.084-7.996). Conclusions: KTP with higher malnutrition risk score were associated with worse outcomes and GS. The nutritional screening tool is easy to be used in clinical practice to evaluate the patient in preparation for kidney transplant.

RESUMO Antecedentes: A prevalência de pacientes desnutridos antes do transplante e a influência da desnutrição nos desfechos do enxerto e do paciente permanecem subestimadas, embora estejam associadas a maior morbimortalidade pós-operatória. Este estudo buscou desenvolver uma ferramenta simples de triagem nutricional e avaliar o impacto do estado nutricional no desfecho clínico, sobrevida do enxerto (SE) e risco de mortalidade em pacientes transplantados renais (PTR). Métodos: Neste estudo de coorte retrospectivo incluindo 451 PTR, desenvolvemos um escore usando medidas antropométricas, clínicas e laboratoriais tomadas na avaliação pré-transplante. Os pacientes foram estratificados em 3 grupos segundo a pontuação final: G1 (0-1 ponto) = baixo risco, G2 (2-4 pontos) = risco moderado e G3 (>5 pontos) = alto risco de desnutrição. Eles foram monitorados por pelo menos 1 a 10 anos após o transplante. Resultados: Os 451 pacientes foram estratificados em G1, G2 e G3, que consistiram em 90, 292 e 69 pacientes, respectivamente. Os pacientes do G1 mantiveram os menores níveis de creatinina sérica na alta hospitalar em relação aos demais (p = 0,012). A incidência de infecção nos pacientes do G3 foi maior que nos pacientes do G1 e G2 (p = 0,030). Os pacientes do G3 apresentaram SE pior do que os pacientes do G1 (p = 0,044) e um risco quase três vezes maior de perda do enxerto (HR 2,94; IC 95% 1,084-7,996). Conclusões: PTR com maior escore de risco de desnutrição foram associados a piores desfechos e menor SE. A ferramenta de triagem nutricional é fácil de usar na prática clínica para avaliar pacientes em preparação para transplante renal.

Impact of preoperative body composition in patients with renal cell carcinoma submitted to surgical treatment / Impacto da composição corporal pré-operatória em pacientes com carcinoma de células renais submetidos a tratamento cirúrgico

Abstract Objective: To evaluate the impact of preoperative body composition in patients with renal cell carcinoma (RCC) undergoing surgical treatment. Materials and Methods: This was a retrospective study of 52 patients with RCC undergoing total or partial nephrectomy. Body composition assessment was performed using the body mass index, together with computed tomography analysis at the level of the third lumbar vertebra to measure the area of visceral adipose tissue, as well as the area and density of skeletal muscle mass. Results: Malnutrition, obesity and inadequate skeletal muscle gauge (SMG) were associated with higher hospital length of stay (p = 0.028, p = 0.02 and p = 0.012, respectively). Although the rates of postoperative symptoms and readmissions were low, survival was better among the patients with an adequate SMG than among those with an inadequate SMG (p = 0.003). Conclusion: Among patients with RCC undergoing surgical treatment, preoperative body composition does not seem to be associated with the rates of perioperative complications, although an inadequate SMG seems to be associated with worse overall survival.

Resumo Objetivo Avaliar o impacto da composição corporal pré-operatória em pacientes portadores de carcinoma de células renais (CCR) submetidos a tratamento cirúrgico. Materiais e Métodos: Foi realizado estudo retrospectivo de 52 pacientes portadores de CCR submetidos a tratamento cirúrgico. A avaliação da composição corporal foi realizada por meio do índice de massa corporal e análise da L3 obtida pela tomografia computadorizada para mensurar a área do tecido adiposo visceral, área e densidade da massa muscular esquelética. Resultados: Os pacientes desnutridos, obesos e que apresentaram produto muscular esquelético (PME) inadequado permaneceram mais tempo internados (p = 0,028, p = 0,02 e p = 0,012, respectivamente). As taxas de sintomas e reinternações no pósoperatório foram baixas em toda a amostra, no entanto, observou-se que pacientes com PME inadequado apresentaram uma pior sobrevida em relação aos pacientes com PME adequado (p = 0,003). Conclusão: A análise da composição corporal pré-operatória não mostrou associação com as taxas de complicações periope-ratórias em pacientes portadores de CCR submetidos a nefrectomia total ou parcial, no entanto, a inadequação do PME está associada a uma pior sobrevida.

High Platelet-to-Lymphocyte Ratio is Associated with Dynapenia in COVID-19 Inpatients: a Case-Control Study / Elevada Relação Plaqueta-Linfócito Está Associada com a Dinapenia em Pacientes Hospitalizados com COVID-19: um Estudo Caso-Controle

SARS-CoV-2 virus infection can cause a cytokine storm leading to symptoms like fever, fatigue, anorexia, and myalgia, which are associated with impaired nutritional status including dynapenia. However, few studies have examined the relationship between dynapenia and prognostic markers in COVID-19 patients. This study aimed to evaluate the occurrence of dynapenia in hospitalized COVID-19 patients and investigate its association with prognostic markers. This study was a case-control design, including inpatients with and without a COVID-19 diagnosis. The occurrence of dynapenia was evaluated according to the European Working Group on Sarcopenia 2 criteria. Additionally, inflammatory markers and 4C Mortality Score were assessed. The study sample consisted of 96 patients, and there were no differences between groups regarding age (p=0.656), sex (p=0.777), presence of comorbidities such as type 2 diabetes (p=0.659) and systemic arterial hypertension (p=0.427), and Body Mass Index (p=0.657). Dynapenia was observed in 53.1% of patients with COVID-19. Dynapenic COVID-19 patients had a lower mean Phase Angle (p=0.029), hematocrit (p=0.046), and hemoglobin (p=0.045) and higher Platelet-to-Lymphocyte Ratio (p=0.089). The occurrence of dynapenia in patients with COVID-19 was associated with Phase Angle <5º (p = 0.013) and high PLR >180 (p = 0.019) (markers of worse inflammatory prognosis). Dynapenia was associated with high PLR and PA, but did not relate to other prognostic variables. These findings emphasize the importance of evaluating muscle strength and quality to prevent and/or treat dynapenia.(AU)

A infecção pelo vírus SARS-CoV-2 pode causar uma tempestade de citocinas levando a sintomas como febre, fadiga, anorexia e mialgia, que estão associados a um estado nutricional comprometido, incluindo a dinapenia. No entanto, poucos estudos examinaram a relação entre dinapenia e marcadores prognósticos em pacientes com COVID-19. Este estudo teve como objetivo avaliar a ocorrência de dinapenia em pacientes hospitalizados com COVID-19 e investigar sua associação com marcadores prognósticos. Este é um estudo caso-controle, incluindo pacientes internados com e sem diagnóstico de COVID-19. A dinapenia foi avaliada de acordo com os critérios do Grupo de Trabalho Europeu sobre Sarcopenia 2. Marcadores inflamatórios e o Escore de Mortalidade 4C também foram avaliados. 96 pacientes foram avaliados, e não houve diferenças entre os grupos em relação à idade (p=0,656), sexo (p=0,777), presença de comorbidades como diabetes tipo 2 (p=0,659) e hipertensão arterial sistêmica (p=0,427) e Índice de Massa Corporal (p=0,657). A dinapenia foi observada em 53,1% dos pacientes com COVID-19. Pacientes com COVID-19 e dinapenia apresentaram uma média menor de Ângulo de Fase (p=0,029), hematócrito (p=0,046) e hemoglobina (p=0,045), e uma maior relação plaquetas/linfócitos (RPL) (p=0,089). A ocorrência de dinapenia em pacientes com COVID-19 foi associada a um Ângulo de Fase <5º (p=0,013) e uma RPL alta >180 (p=0,019) (marcadores de pior prognóstico inflamatório). A dinapenia foi associada a RPL alta e Ângulo de Fase, mas não se relacionou com outras variáveis prognósticas. Esses achados enfatizam a importância de avaliar a força muscular e a qualidade para prevenir e/ou tratar a dinapenia.(AU)

Associação do risco nutricional com parâmetros clínicos e nutricionais de pacientes internados em um hospital universitário / Association of nutritional risk with clinical and nutritional parameters of patients hospitalized in a university hospital

Introdução: O reconhecimento do risco nutricional na admissão do indivíduo hospitalizado é fundamental, pois possibilita que intervenções nutricionais adequadas e especializadas sejam implementadas precocemente. Objetivo: Identificar o risco nutricional dos pacientes internados e associar com parâmetros clínicos e nutricionais. Materiais e Métodos: O estudo foi transversal, descritivo, cuja amostra foi não-probabilística, realizado em pacientes com faixa etária superior a 18 anos admitidos nas enfermarias de clínica médica e cirúrgica do Hospital Universitário da Universidade Federal de Juiz de Fora (HU-UFJF/Ebserh). Para identificação do risco nutricional, foi aplicado instrumento de triagem nutricional (NRS-2002) na admissão hospitalar, além da verificação de peso, altura, dados demográficos (sexo, idade, raça/cor), clínicos (diagnóstico médico, tipo e número de comorbidades, tempo de internação hospitalar e desfecho clínico) e nutricionais (risco nutricional, uso e tempo em terapia nutricional). Para as associações estatísticas, foram utilizados os testes qui-quadrado ou exato de Fisher (a depender do tamanho amostral) para as variáveis categóricas e teste de Mann-Witney, para as variáveis contínuas. Em todas as análises foi considerado o nível de significância de 0,05. Resultados: Foram avaliados ao final 147 pacientes, sendo 74 (50,34%) do sexo feminino, 94 (63,95%) de raça/cor branca e 91 (61,90%) adultos. Apenas 15,65% desta população apresentou risco nutricional e este parâmetro foi associado aos indivíduos com doenças hematológicas (p= 0,02) e pulmonares (p= 0,02), àqueles em uso de terapia nutricional (p<0,01), ao maior tempo de internação (p<0,01) e ao menor Índice de Massa Corporal (IMC) (p= 0,02). Os pacientes em risco que fizeram uso de terapia nutricional permaneceram mais dias internados. Conclusão: Este estudo revelou que o risco nutricional, determinado pela NRS-2002, apresentou associação significativa à presença de doenças hematológicas e pulmonares, bem como ao uso de terapia nutricional, número de dias em uso de terapia nutricional, maior tempo de internação hospitalar e menor IMC, estando em concordância com outros trabalhos. Os resultados poderão contribuir para a melhoria do serviço e do tratamento dos pacientes internados.

Introduction: The recognition of the nutritional risk in the admission of the hospitalized individual is essential, as it allows appropriate and specialized nutritional interventions to be implemented early. Objective: To identify the nutritional risk of hospitalized patients and associate with clinical and nutritional parameters. Materials and Methods: The study was cross-sectional, descriptive, whose sample was non-probabilistic, carried out on patients aged over 18 years admitted to the medical and surgical clinic wards of the University Hospital of the Federal University of Juiz de Fora (HU-UFJF/Ebserh). To identify the nutritional risk, a nutritional screening instrument (NRS-2002) was applied on hospital admission, in addition to checking weight, height, data demographic (gender, age, race/color), clinical (medical diagnosis, type and number of comorbidities, hospital length of stay and clinical outcome) and nutritional (nutritional risk, use and time in nutritional therapy). For statistical associations, the chi-square test or Fisher's exact test (depending on the sample size) were used for categorical variables and the Mann-Witney test for continuous variables. In all the analyzes considered a significance level of 0,05. Results: In the end, 147 patients were evaluated, 74 (50,34%) females, 94 (63,95%) white and 91 (61,90%) adults. Only 15,65% of this population presented nutritional risk and this parameter was associated with individuals with hematological (p= 0,02) and pulmonary (p= 0,02) diseases, those using nutritional therapy (p<0,01), longer hospital lengths of stay (p<0,01) and lower Body Mass Index (BMI) (p= 0,02). Patients at risk who used nutritional therapy spent more days in hospital. Conclusion: This study revealed that nutritional risk, determined by NRS-2002, was significantly associated with the presence of hematological and pulmonary diseases, as well as the use of nutritional therapy, number of days using nutritional therapy, longer hospital stay and lower BMI, agreeing with other studies. The results may contribute to improving the service and treatment of hospitalized patients.

The geriatric nutritional risk index predicts complications after nephrectomy for renal cancer

ABSTRACT Purpose: We examined if malnutrition, as defined by the Geriatric Nutritional Risk Index (GNRI), is independently associated with 30-day postoperative complications in patients undergoing nephrectomy for the treatment of renal cancer. Materials and methods: Using the American College of Surgeons National Surgical Quality Improvement Program database from 2006-2019, we identified patients ≥65 years old who underwent nephrectomy for renal cancer. The following formula for GNRI was used to define preoperative nutritional status: 1.489 x serum albumin (g/L) + 41.7 x (current body weight [kg]/ ideal body weight [kg]). Based on the GNRI, patients were classified as having no (> 98), moderate (92-98), or severe malnutrition (< 92). After adjusting for potential confounders, multivariable logistic regression analyses were performed to assess the association between GNRI and 30-day postoperative complications. Odds ratios (OR) with 95% confidence intervals (CI) were reported. Results: A total of 7,683 patients were identified, of which 1,241 (16.2%) and 872 (11.3%) had moderate and severe malnutrition, respectively. Compared to normal nutrition, moderate and severe malnutrition were significantly associated with a greater odds of superficial surgical site infection, progressive renal insufficiency, readmission, extended length of stay, and non-home discharge. Severe malnutrition was also associated with urinary tract infection (OR 2.10, 95% CI 1.31-3.35) and septic shock (OR 2.93, 95% CI 1.21-7.07). Conclusion: Malnutrition, as defined by a GNRI ≤ 98, is an independent predictor of 30-day complications following nephrectomy. The GNRI could be used to counsel elderly patients with renal cancer prior to nephrectomy.

Risk assessment and nutritional prognosis of clinical outcome in critically ill patients / Avaliação do risco e prognóstico nutricional com relação ao desfecho clínico de pacientes críticos

INTRODUCTION: Nutrition assessment of critically ill patients is challenging but it should be part of the clinical nutrition routine in the hospital setting. OBJECTIVE: To assess the nutritional risk and prognosis of patients admitted to the intensive care unit (ICU) of a University Hospital in Natal, Brazil. METHODS: Cross-sectional study developed with adult and elderly patients between February 2017 and February 2020. The nutritional risk was detected by the modified Nutrition Risk in Critically Ill score (mNUTRIC score). The nutritional prognosis was assessed using the phase angle (PA), calculated from the resistance and reactance values provided by bioimpedance. Mann-Whitney test was used to verify the association of mNUTRIC-score and PA with the outcome (hospital discharge or death). Spearman's correlation coefficient was used to verify the correlation between mNUTRIC-score and PA. RESULTS: A total of 55 patients were included in this study. The average value of the NUTRIC score and PA was 3.13 ± 2.35 and 4.19 ± 1.21, respectively. Most patients had low nutritional risk. Among them, 81.8% were discharged and 18.2% died. Both mNUTRIC-score (p≤0.0001) and PA (p=0.04) were associated with the clinical outcome. These two parameters were negatively correlated (r=-0.3804; p=0.0059). CONCLUSION: Most of the patients had a low nutritional risk determined by the mNUTRIC-score. Those with high nutritional risk had a worse outcome (death). A negative correlation was observed between the mNUTRIC score and the PA, showing that the higher the nutritional risk, the worse prognosis was found in critically ill patients.

INTRODUÇÃO: A avaliação do estado nutricional de pacientes críticos é um desafio, mas faz parte da rotina da nutrição clínica hospitalar. OBJETIVO: Avaliar o risco e o prognóstico nutricional, e suas relações, em pacientes críticos admitidos na unidade de terapia intensiva (UTI) de um hospital universitário em Natal, Brasil. MÉTODOS: Estudo transversal, desenvolvido com pacientes adultos e idosos entre fevereiro de 2017 e fevereiro de 2020. O risco nutricional foi detectado pelo Nutrition Risk in Critically ill score modificado (mNUTRIC-score). O prognóstico nutricional foi avaliado mediante o ângulo de fase (AF). O teste de Mann-Whitney foi usado para verificar a associação do mNUTRIC-score e do AF com os desfechos (alta da UTI ou óbito). A correlação de Spearman foi usada para verificar a correlação entre o mNUTRIC-score e o AF. RESULTADOS: Ao total, 55 indivíduos foram incluídos no estudo. O valor médio do mNUTRIC-score foi de 3,13 ± 2,35 e do AF foi de 4,19 ± 1,21. A maioria dos pacientes apresentaram baixo risco nutricional (76,4%) e tiveram alta da UTI (81,8%). Tanto o mNUTRIC-score (p<0,0001) como o AF (p=0,04) estiveram associados com o desfecho clínico. Esses dois parâmetros se correlacionaram negativamente (r= -0,3804; p=0,0059). CONCLUSÃO: A maioria dos pacientes críticos estudados apresentaram baixo risco nutricional determinado pelo mNUTRIC-score. Aqueles com alto risco nutricional tiveram pior desfecho (óbito). Observou-se correlação negativa entre o mNUTRIC-score e o AF, demostrando que quanto maior o risco nutricional, pior o prognóstico clínico e nutricional em pacientes críticos.

Evaluation of malnutrition frequency and related factors of geriatric patients in need of home healthcare

SUMMARY OBJECTIVE: The nutritional status of frail elderly people receiving home health services should be evaluated. This study aimed to determine the nutritional status of patients aged ≥65 years registered in the Home Healthcare Services unit and investigate the factors that may be associated with malnutrition. METHODS: This cross-sectional descriptive study was conducted during routine visits to patients and their caregivers. A total of 161 patients were asked to fill in surveys asking about sociodemographic characteristics, patient history, and clinical status. Anthropometric measurements were taken from all patients. The Mini Nutritional Assessment Short Form was applied to the patients for screening purposes. Patients who scored ≤11 on the Mini Nutritional Assessment Short Form were then asked to complete the full Mini Nutritional Assessment form. RESULTS: According to the Mini Nutritional Assessment Short Form and Mini Nutritional Assessment tests, almost half of the elderly patients included in the study (49.7%, n=161) were malnourished or at risk of malnutrition. Analyses showed that those who had COVID-19 [odds ratio (OR): 9.423, 95%CI 2.448-36.273) and those diagnosed with dementia/depression (OR: 8.688, 95%CI 3.246-23.255) were more likely to be malnourished, whereas those with diabetes (OR: 0.235, 95%CI 0.084-0.657) were less likely to have malnutrition. Strikingly, those who were fed by caregivers (OR: 15.061, 95%CI 3.617-62.710) were also more likely to be malnourished than those with self-feeding ability. CONCLUSION: Malnutrition or the risk of malnutrition is common in elderly patients receiving home care services. Many factors can have an impact on malnutrition.

Estado nutricional e consumo alimentar de idosos residentes em uma instituição asilar de Feira de Santana- Bahia / Nutritional status and food intake of elderly residents of a nursing home in Feira de Santana - Bahia

O Estado Nutricional (EN) exerce grande influência na morbimortalidade de idosos institucionalizados, e a sua avaliação permite definir uma intervenção nutricional individualizada. Esse estudo objetivou avaliar o estado nutricional e o consumo alimentar de idosos residentes de uma instituição de longa permanência. Trata-se de um estudo transversal, realizado com 37 idosos institucionalizados residentes, no ano de 2019. O EN foi avaliado pelo questionário da Mini Avaliação Nutricional (MAN). O consumo alimentar foi obtido através da pesagem total dos alimentos, verificando sua adequação de acordo com as recomendações para idade. As diferenças entre variáveis foram testadas por meio do teste t de Student e o teste de Mann-Whitney. As associações entre variáveis foram investigadas com auxílio dos coeficientes de correlação de Pearson e Spearman. As prevalências de desnutrição e risco de desnutrição nos idosos foram de 21,6% e 73%, respectivamente. O Índice de Massa Corporal (IMC) demonstrou predominância de baixo peso nos homens (38,9%) e sobrepeso nas mulheres (47,4%). Foi encontrado consumo excessivo de carboidratos e proteínas na população, sendo que, a ingestão de energia, proteínas e lipídios foi superior entre o grupo masculino. A circunferência do braço (p= 0,007), necessidade energética estimada (p= 0,049) e IMC (p <0,001) foram associados positivamente com a MAN. Os resultados demonstraram que, esses idosos são caracterizados por alto risco nutricional associado a alterações na composição corporal, e inadequações nutricionais. Sugerindo que, independente do consumo alimentar estar adequado em quantidade, não foi suficiente para prevenir o quadro de desnutrição nos idosos institucionalizados.(AU)

The Nutritional Status (NS) has a great influence on the morbidity and mortality of institutionalized elderly, and its evaluation allows to define of an individualized nutritional intervention. This study aimed to assess the nutritional status and food consumption of elderly residents of a long-term institution. This is a cross-sectional study carried out with 37 institutionalized elderly residents in 2019. The NS was assessed by the Mini Nutritional Assessment (MNA) questionnaire. Dietary intake was obtained through total weighing of the food, checking its adequacy according to the recommendations for age. Differences between variables were tested using the Student's t-test and the Mann-Whitney test. Associations between variables were investigated with the aid of Pearson and Spearman correlation coefficients. The prevalence of malnutrition and risk of malnutrition in the elderly was 21.6% and 73%, respectively. The Body Mass Index (BMI) showed a predominance of low weight in men (38.9%) and overweight in women (47.4%). Excessive consumption of carbohydrates and proteins was found in the population, and the intake of energy, proteins, and lipids was higher among the male group. Arm circumference (p = 0.007), estimated energy requirement (p = 0.049) and BMI (p <0.001) were positively associated with MAN. The results demonstrate that these elderly people are characterized by the high nutritional risk associated with changes in body composition, and nutritional inadequacies. Suggesting that, regardless of whether food intake was adequate in quantity, it was not enough to prevent malnutrition in institutionalized elderly.(AU)

Observational study of GLIM standard and SGA in the diagnosis of severe malnutrition in neurosurgery patients / 肠外与肠内营养

Objective:To compare the application of GLIM and SGA in diagnosing malnutrition among severe neurosurgery patients.Methods:According to random sampling,42 patients admitted to the intensive care unit of Department of Neurotrauma in a Grade-A hospital in Guangzhou from January 2023 to April 2023 were screened.The nutritional status was assessed using GLIM standard and SGA scale,respectively.GLIM criteria and SGA scale were compared in the diagnosis of malnutrition.Results:The patients'NRS 2002 score was(3.90±1.10),and the positive rate of nutritional screening risk was 100％(42/42).13 patients were diagnosed as malnutrition by GLIM criteria,with a positive rate of 30.95％.29 cases were diagnosed as malnutrition by SGA,and the positive rate was 69.05％.The Kappa value of GLIM standard and SGA scale for malnutrition was 0.372,and the difference between the two nutritional status assessment tools was statistically significant(P＜0.05).Conclusion:Patients receiving neurocritical surgery had high nutritional risk and had a low incidence of malnutrition under GLIM criteria,while a high incidence of malnutrition under SGA criteria.Moreover,the results of GLIM criteria and SGA were not consistent in the assessment of malnutrition.

The impact of nutritional status on postoperative complications in elderly patients with right-sided colon cancer / 国际外科学杂志

Objective:To explore the correlation between preoperative nutritional status and postoperative complications in elderly patients with right-sided colon cancer.Methods:A prospective registry database of 1, 196 patients undergoing curative surgery for right-sided colon cancer was collected from 52 top-tier hospitals nationwide between September 2021 and June 2022. The cohort included 627 males and 569 females, with an age range of 64(53, 71) years. Among these, 136 patients developed complications, while 1, 060 did not. Patients were divided into two groups based on age: the elderly group(≥65 years, n=571) and the middle-aged group(<65 years, n=625). Preoperative nutritional assessment indicators, clinical pathological data, and the incidence of complications within 30 days post-surgery were collected. For normally distributed quantitative data, mean ± standard deviation( ± s) was used, and the t-test was applied for intergroup comparisons. Non-normally distributed quantitative data were represented as M( Q1, Q3) and analyzed using the Wilcoxon rank-sum test; categorical data were compared using the chi-square test or Fisher′s exact test. In the analysis of risk factors for postoperative complications in elderly patients, univariate analysis was first conducted on all potential risk factors, followed by the inclusion of statistically significant variables from univariate regression into a multivariate logistic regression model. Results:The overall incidence of postoperative complications was 11.37%(136/1 196), with common complications includin wound infection(2.26%), intestinal obstruction (2.26%), anastomotic leakage(1.42%), deep vein thrombosis(1.42%), and chylous leakage(1.42%). In the elderly group, the proportion of patients with preoperative nutritional risk who developed complications was significantly higher than those without complications(66.20% vs. 53.40%, P=0.043). In the multivariate analysis, body mass index( OR=1.058, 95% CI: 1.005-1.117, P=0.031) and nutritional risk( OR=1.803, 95% CI: 1.066-3.126, P=0.031) were identified as independent risk factors for postoperative complications in elderly patients. Conclusions:There is a correlation between preoperative nutritional status and the occurrence of postoperative complications in elderly colon cancer patients, particularly with respect to body mass index and nutritional risk. These findings underscore the importance of preoperative nutritional assessment and intervention in elderly patients to reduce the risk of postoperative complications.

Research progress on perioperative nutritional management for gastric cancer / 实用肿瘤学杂志

Gastric cancer is one of the common tumors in the world and a major cause of cancer death.Although the 5-year survival rate of gastric cancer patients has increased greatly with the improvement levels of diagnosis and treatment,the high malnutri-tion rate of gastric cancer patients still has a significant impact on their overall survival and quality of life.Malnutrition is considered an independent prognostic factor for cancer patients,early detection of malnutrition in gastric cancer patients and more reasonable peri-operative nutritional support play an important role in the survival and prognosis of gastric cancer patients.This article combines exist-ing research at domestic and abroad to review the nutritional risk screening and assessment of gastric cancer patients during periopera-tive period,as well as the research progress of perioperative nutritional support and immunonutrition,in order to provide more compre-hensive nutritional management strategies for patients with gastric cancer during the perioperative period.

Analysis of risk factors affecting the completion of postoperative adjuvant chemotherapy in elderly patients with progressive gastric cancer / 中华老年医学杂志

Objective:To investigate the risk factors affecting the completion of postoperative adjuvant chemotherapy in elderly patients with progressive gastric cancer.Methods:Clinicopathological data of patients diagnosed with gastric adenocarcinoma and treated with radical surgery at our hospital between January 2017 and December 2018 were retrospectively collected, and 96 patients were finally included in the study according to the inclusion and exclusion criteria.Patients were divided into a completed chemotherapy group and an uncompleted chemotherapy group depending on whether they had completed 6 cycles of adjuvant chemotherapy after surgery.The optimal cut-off value was derived from the receiver operating characteristic(ROC)curve, and the Youden Index was calculated.Relevant factors that might affect the completion of postoperative adjuvant chemotherapy in elderly patients with progressive gastric cancer were included in univariate and multivariate Logistic regression analyses to identify independent risk factors affecting the completion of postoperative adjuvant chemotherapy in gastric cancer patients.The Kaplan-Meier(K-M)method was used to plot the survival curves for the groups, and the log-rank test was used to compare the survival rates between the groups.Results:A total of 96 patients, aged 60-89 years, with a mean age of(70.3±7.0)years, were included.Sixteen patients completed postoperative adjuvant chemotherapy, while 80 patients did not.The following analysis was performed on clinicopathological data of patients in the two groups.Univariate Logistic regression analysis showed that patient age ≥70 years( OR=8.135, 95% CI: 1.735-38.153, P=0.008)or a preoperative prognostic nutritional index(PNI)score <49.5( OR=4.765, 95% CI: 1.549-14.656, P=0.006)affected the completion of postoperative adjuvant chemotherapy.The risk factors that might affect the completion of postoperative adjuvant chemotherapy in elderly gastric cancer patients were analyzed using multivariate Logistic regression and the results showed that age ≥70 years( OR=9.815, 95% CI: 1.947-49.485, P=0.006)and a preoperative PNI score <49.5( OR=5.895, 95% CI: 1.711-20.305, P=0.005)were independent risk factors hindering the completion of postoperative adjuvant chemotherapy. Conclusions:Age ≥70 years and PNI<49.5 are independent risk factors for the completion of postoperative adjuvant chemotherapy.Failure to complete postoperative adjuvant chemotherapy is associated with a poor prognosis.PNI is a valid predictor for whether postoperative adjuvant chemotherapy will be completed and helps to screen chemotherapy patients who need nutritional intervention.

Progress of systemic immune-inflammatory index for predicting the prognosis of digestive system tumors / 肿瘤研究与临床

Systemic immune-inflammation index is an effective index reflecting the inflammation and immune state of the body. The calculation formula is platelet count×neutrophil count/lymphocyte count. Because the test of SII is simple and does not increase the burden of patients, SII has been applied to the prognosis assessment of patients with various types of tumors. There are many studies on SII for predicting the prognosis of esophageal cancer, gastric cancer and colorectal cancer after treatment. The patients with higher SII have poorer prognosis. The combination of SII and other inflammatory index will have higher clinical application value.
