Validity of the GLIM criteria for the diagnosis of malnutrition in patients with colorectal cancer: A multicenter study on the diagnostic performance of different indicators of reduced muscle mass and disease severity.

OBJECTIVES: To assess the concurrent and predictive validity of different combinations of Global Leadership Initiative on Malnutrition (GLIM) criteria in patients with colorectal cancer considering different indicators of reduced muscle mass (MM) and the effects of the disease. METHODS: A secondary analysis with patients with colorectal cancer. The reduced MM was assessed by arm muscle area, arm muscle circumference, calf circumference, fat-free mass index, skeletal muscle index (SMI) and skeletal muscle. Cancer diagnosis or disease staging (TNM) was considered for the etiologic criterion referred to as the effect of the disease. The other phenotypic and etiologic criteria were also evaluated, and we analyzed 13 GLIM combinations. Concurrent validity between GLIM criteria and Patient-Generated Subjective Global Assessment was evaluated. Logistic and Cox regression were used in the predictive validation. RESULTS: For concurrent validity (n = 208), most GLIM combinations (n = 6; 54.5%) presented a moderate agreement with Patient-Generated Subjective Global Assessment and none showed satisfactory sensitivity and specificity (>80%). Reduced MM evaluated by SMI and SMI were present in the GLIM combinations associated with postoperative complications (odds ratio, ≥2.0), independent of other phenotypic and etiologic criteria. The combinations with reduced MM considering any method and fixed phenotypic criteria and TNM were associated with mortality (hazard ratio, ≥2.0). CONCLUSIONS: Satisfactory concurrent validity was not verified. The GLIM diagnosis of malnutrition was associated with postoperative complications and mortality.

Nutritional management during critical illness in those with previous obesity surgery.

PURPOSE OF REVIEW: The prevalence of overweight and obesity in our society is a pressing concern that has demanded immediate attention. Traditional treatments have proven ineffective for many individuals, leading to a surge in bariatric surgery as a last resort. While the rate of early and late postoperative complications may be low, when they occur, they place these patients at higher risk of requiring intensive care treatment. Therefore, it is our aim to discuss the nutritional care of these individuals. RECENT FINDINGS: Nutritional management of critically ill postbariatric surgical patients is related to the difficulty of providing an adequate nutritional assessment, calculating the macro and micronutrient requirements, choosing the right therapy, and defining the timely moment to initiate it. The anatomic changes related to the bariatric operation pose a high risk for a nonfunctional gastrointestinal tract both in the early postoperative and late postoperative. Therefore, the route of nutrition will greatly rely on the absorptive capacity, as well as on the nutritional status, with parenteral nutrition being an early option, especially for those with high critical care severity scores. Also, these patients are known to have an altered microbiota which may influence the absorptive capacity. Immunonutrition, prebiotics, probiotics, and symbiotics may represent potential options, but there is currently little support for 'one size fits all'. SUMMARY: The nutritional care of critically ill patients postbariatric surgery is a complex and nuanced process requiring a multifaceted precision approach. The distinct nutritional challenges of early and late postoperative patients necessitate a thorough nutritional assessment and a highly individualized nutritional care plan.

Comparison of pre- and posttransplant energy expenditure in patients undergoing hematopoietic stem cell transplantation and evaluation of associated factors.

OBJECTIVES: Patients undergoing hematopoietic stem cell transplantation may present with metabolic alterations that can have an effect on their energy expenditure and nutritional status. This project aimed to compare the pre- and posttransplant energy expenditures of patients undergoing hematopoietic stem cell transplantation as well as related factors. METHODS: This prospective study was conducted at a single center. Patients, undergoing autograft or allograft, were evaluated before transplantation and on the 10th and 17th d posttransplantation. Energy expenditure was measured by indirect calorimetry. Diet intake was assessed by a 24-h dietary recall. Infectious and noninfectious complications were analyzed between days 1 to 10 after transplantation and days 11 to 17 after transplantation. Paired model analyses were carried out to identify the pretransplantation and posttransplantation periods. RESULTS: Twenty patients were evaluated with a mean age of 45.6 ± 17.2 y; a majority were male sex (65%), and the most frequent diagnoses were chronic myeloid leukemia (25%) and multiple myeloma (25%). Energy expenditure increased by 15% posttransplantation, and the energy requirement per kilogram of weight was 23 kcal/kg at day 10 after transplantation. Throughout the posttransplantation period, 45% of the patients required nutritional therapy. Negative energy and negative protein balance were observed at all analyzed times. Phase angle (P = 0.018), fever (P = 0.014), mucositis grades I to II (P = 0.018), and the total number of infectious and noninfectious events (P = 0.043) were associated with an increase in energy expenditure at day 10 after transplantation. CONCLUSIONS: Energy expenditure increased after transplantation compared with pretransplantation in 50% of patients. Phase angle, fever, grades I to II mucositis, and infectious and noninfectious events were associated with increased energy expenditure at day 10 after transplantation.

Exploring the use of the GLIM criteria to diagnose malnutrition in cancer inpatients.

OBJECTIVES: The Global Leadership Initiative on Malnutrition (GLIM) criteria establish a diagnosis of malnutrition based on the presence of at least one phenotypic and one etiologic criterion. This study aimed to assess the concurrent and predictive validity of the GLIM criteria in hospitalized cancer patients. METHODS: This is an observational retrospective study, including 885 cancer patients, ages >18 y, admitted to a medical oncology inpatient unit between 2019 and 2020. All patients at risk for malnutrition according to the Nutritional Risk Screening 2002 score were assessed by the subjective global assessment (SGA) and 14 different combinations of the GLIM criteria. The SGA was considered the gold standard for assessing the concurrent validity of the GLIM combinations. For a subsample of patients with data available on inflammatory markers (n = 198), the serum albumin and C-reactive protein were included in the combinations as etiologic criteria. The predictive validity of the different combinations was tested using the occurrence of surgical complications as the clinical outcome. The sensitivity and specificity values were calculated to assess the concurrent validity, univariate and multivariate logistic regression models were used to test predictive validity. Adequate concurrent and predictive validity were determined as sensitivity and specificity values >80% and odds ratio values ≥2.0, respectively. RESULTS: The median age of the patients was 61.0 y (interquartile range = 51.0-70.0). Head and neck cancer was the prevailing diagnosis and 375 patients were at nutritional risk. According to the SGA, 173 (26.1%) patients were malnourished (SGA categories B or C) and the prevalence of malnutrition ranged from 3.9% to 30.0%, according to the GLIM combinations. None of the tested combinations reached adequate concurrent validity; however, the presence of malnutrition according to four combinations independently predicted surgical complications. CONCLUSIONS: The predictive validity of the GLIM was satisfactory in surgical cancer patients.

Findings from Positron Emission Tomography-Computed Tomography with 18F-Fluorodeoxyglucose Uncover a Potential Marker of Nutritional Status in Cancer Patients: A Cross-Sectional Pilot Study.

BACKGROUND: Cancer patients often have altered nutritional status and periodically undergo imaging tests. We hypothesized that standard uptake values (SUV) by positron emission tomography-computed tomography (PET/CT) with 18 F-fluorodeoxyglucose (18F-FDG) could be associated with the nutritional status of cancer patients. MATERIALS AND METHODS: Adult cancer patients who underwent clinical evaluation and PET/CT with 18 F-FDG on the same day were included in a cross-sectional pilot study. The focus was on evaluating 18 F-FDG findings with regard to nutritional status, with an emphasis on liver SUVmean and tumor SUVmax. RESULTS: A total of 179 patients were evaluated. One hundred and three (57.5%) were classified as well-nourished, 54 (30.1%) as suspected/moderately malnourished, and 22 (12.2%) as severely malnourished. The median hepatic SUVmean was 2.29, with 1.87 corresponding to the 10th percentile. There was a significant difference between the severely malnourished (2.02) and well-nourished or suspected/moderately malnourished (2.36) patients. Severely malnourished patients were more likely to have a SUVmean < 1.87 (p = .035). The tumor SUVmax also was significantly higher in severely malnourished patients (p = .003). CONCLUSION: Cancer patients with severe malnutrition have lower values of hepatic SUVmean and higher values of tumor SUVmax in PET/CT with 18F-FDG when compared to well-nourished patients.

Nutrition competencies for undergraduate medical education: Results of an international interdisciplinary consensus.

BACKGROUND: The gap between the nutrition education provided to medical students and the nutrition competencies and attitudes needed for physicians to provide adequate nutrition care is a global concern. There is no universally accepted benchmark on nutrition competencies for doctors. The objective of this study was to establish, by expert consensus, the objectives of undergraduate nutrition medial education, the nutrition core competencies, and strategies for curriculum development in medical nutrition education. METHODS: We administered a Delphi survey to systematically gather the opinion of a panel of Latin American experts in nutrition. The survey questionnaire was constructed considering scientific literature by using a 5-point Likert scale. Consensus was defined as >70% agreement on the importance of an item (Likert scale 4 and 5). RESULTS: A four-round Delphi survey was conducted for this research. In the second, third, and fourth rounds, we validated a total of 130 competencies by consensus, which were distributed into four different thematic areas: (1) basic nutrition concepts, (2) public nutrition and nutrition prevention throughout the life cycle, (3) nutrition status and disease, and (4) nutrition care process. CONCLUSION: The curricula for general physician education in medical school must include health promotion, prevention, and treatment of diseases related to nutrition. This goal can be reached by integrating ≤130 competencies into four different fundamental areas.

SHORT-TERM EFFECT OF WHEY PROTEIN SUPPLEMENTATION ON THE QUALITY OF LIFE OF PATIENTS WAITING FOR LIVER TRANSPLANTATION: A DOUBLE BLINDED RANDOMIZED CLINICAL TRIAL.

BACKGROUND: Chronic liver disease is associated with malnutrition that negatively impacts a patient's health-related quality of life (HRQoL). AIM: To evaluate the short-term effect of whey protein supplementation on the HRQoL and nutritional and functional status of patients waiting for liver transplantation. METHODS: This was a double-blind randomized clinical trial with patients waiting for liver transplantation who were randomized into two groups: WP (whey protein supplementation) and the control (casein supplementation). Both groups received 40 g (20 g in the morning and 20 g in the evening) for 15 days. Nutritional and functional status were evaluated. Energy balance was calculated as the difference between energy intake (24-hour recall) and total energy expenditure (assessed by indirect calorimetry). The chronic liver disease questionnaire was used to assess HRQoL. All measurements were performed before and after the intervention. RESULTS: Fifty-six patients were evaluated. Malnutrition was present in 56.9%, and it was directly associated with a poor HRQoL (p<0.05). No improvement on the nutritional and functional status was observed, in either group after protein supplementation. HRQoL improved after WP and casein supplementation, with no differences between groups (p>0.05). Patients who met protein requirements and had a positive energy balance demonstrated a higher HRQoL score (4.9, p<0.05), without between-group differences. CONCLUSION: Malnutrition substantially reduces HRQoL. Short-term WP or casein supplementation improved similarly the HRQoL.

Energy Expenditure and Liver Transplantation: What We Know and Where We Are.

Patients with end-stage liver disease (ESLD) and undergoing liver transplantation (LTx) commonly present with malnutrition attributed to various etiologies. One of the causes is potential hypermetabolism resulting from increased resting energy expenditure (REE). After the surgery, it is hypothesized that these patients show a reduction in REE, which may contribute to the weight gain observed in this population. However, there have been controversial results regarding the metabolic status of ESLD patients and liver recipients, which has led us to critically review the pertinent literature. We enrolled studies with the following goals: assessment of REE of these patients either before or after surgery by using indirect calorimetry (measured REE [mREE]) and comparison of these mREE values with those of healthy controls or with REE values obtained using predictive equations (predicted REE [pREE]). For most patients, mREE and pREE values were comparable. However, ≥5.3% of patients exhibited hypermetabolism when the mREE was compared with the pREE using the Harris-Benedict formula. Three follow-up studies that were conducted postsurgery showed a progressive reduction in the mREE for ≤1 year. However, conflicting data have been published, and cross-sectional studies have not reported hypometabolic patients. In conclusion, there is no consensus regarding the metabolic status of pre-LTx and post-LTx patients, which may be due to differences in the methods used for comparison. Therefore, we highlight this aspect of LTx patient management, which impacts the quality of nutrition therapy required by these patients.

Preoperative and Postoperative Resting Energy Expenditure of Patients Undergoing Major Abdominal Operations.

BACKGROUND: Nutrition therapy plays a major role in the perioperative management of surgical patients. Understanding energy metabolism and correctly establishing the adequate energy needs is a crucial step to provide optimal nutrition care. The aim of this study was to assess the resting energy expenditure (REE) after major abdominal procedures and its associated factors. METHODS: This was a prospective observational study conducted at a single center. REEs of patients admitted for gastrointestinal surgical procedures were measured by indirect calorimetry 24 hours prior to the procedure and reassessed at least once within the fifth postoperative day. Substrate oxidation was calculated according to the Frayn equation. Nutrition status was evaluated using subjective global assessment. RESULTS: There were no significant changes in the REEs throughout the study period; however, there was a decrease in the respiratory quotient during the postoperative period, as well as a decrease in carbohydrate oxidation and an increase in lipid oxidation. Only 33.3% of the patients presented a postoperative increase in REE > 10%. Those patients presented higher blood-monocyte levels. CONCLUSION: Postoperative REE is not increased in most of the patients. In patients who had increased REE, associated factors included higher levels of monocytes.

Short-term effect of whey protein supplementation on the quality of life of patients waiting for liver transplantation: a double blinded randomized clinical trial / Efeito a curto prazo da suplementação com proteína do soro do leite sobre a qualidade de vida de pacientes em fila de espera para o transplante hepático: ensaio clínico randomizado

RESUMO Racional: A doença hepática crônica está associada à desnutrição que afeta negativamente a qualidade de vida relacionada à saúde (QVRS). Objetivo: Avaliar o efeito da suplementação aguda de proteína do soro de leite na QVRS e no estado nutricional e funcional dos pacientes em lista de espera para o transplante hepático. Métodos: Ensaio clínico randomizado com pacientes à espera do transplante hepático que foram randomizados em dois grupos: PS (suplementação com proteína do soro de leite) e Controle (suplementação com caseína). Ambos os grupos receberam 40 g das proteínas (20 g pela manhã e 20 g à noite) por 15 dias. O estado nutricional e funcional foi avaliado. O balanço energético foi calculado como a diferença entre a ingestão energética (recordatório de 24 horas) e o gasto energético total (avaliado por calorimetria indireta). O questionário de doença hepática crônica (CDLQ) foi utilizado para avaliar a QVRS. Todas as medidas foram realizadas antes e após a intervenção. Resultados: Cinquenta e seis pacientes foram avaliados. A desnutrição esteve presente em 56,9% e, diretamente associada à baixa QVRS (p<0,05). A suplementação, com ambas as proteínas, não alterou o estado nutricional e funcional dos pacientes (p>0,05). Entretanto, a QVRS melhorou após a suplementação com PS e caseína, sem diferenças entre os grupos (p>0,05). Pacientes que alcançaram as necessidades proteicas e com balanço energético positivo tiveram maior escore de QVRS (4,9; p<0,05), sem diferenças entre os grupos (p>0,05). Conclusão: A desnutrição reduz substancialmente a QVRS. A suplementação aguda com PS ou caseína melhorou de forma similar a QVRS.

Malnutrition is associated with poor health-related quality of life in surgical patients with gastrointestinal cancer.

OBJECTIVE: The aim of this study was to evaluate the association between preoperative nutritional status and health-related quality of life (HRQoL) in patients with gastrointestinal cancer who were admitted for elective surgical treatment. METHODS: This was a cross-sectional study in which patients with a diagnosis of gastrointestinal cancer were evaluated before a surgical procedure. The nutritional assessment included subjective global assessment (SGA) and measurements of weight loss percentage, bioelectrical impedance, and functional capacity. HRQoL was evaluated by the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30). Statistical analyses were performed with a significance level of 5%. The sample size was calculated based on a pilot study. RESULTS: We evaluated 132 patients, the majority of whom were men. The median age of the patients was 62 y, and the most prevalent tumors were in the colon, rectum, and anus (52.3%). The SGA highlighted the high prevalence of malnutrition (69.9%), which was confirmed by the rates of weight loss (73.8%) and the low fat-free mass index (56.8%). Malnourished patients and patients with severe weight loss had worse functional, symptom, global health and quality of life scores (P < 0.05). Malnutrition, according to the SGA, decreased physical function and role performance scores by 9 and 20 points, respectively (P < 0.05). CONCLUSION: Malnutrition, assessed by various tools, was associated with poor HRQoL of surgical patients with gastrointestinal cancer.

Effect of Oral Nutrition Supplements and TGF-ß2 on Nutrition and Inflammatory Patterns in Patients With Active Crohn's Disease.

BACKGROUND: Crohn's disease (CD) is often associated with nutrition disorders. Many nutrition therapeutic alternatives have been studied. Nevertheless, the actual role of nutrition therapy is still controversial. The objective of this study was to assess the effects of nutrition supplementation with and without transforming growth factor-beta 2 (TGF-ß2) on inflammatory, endoscopic, histopathologic, and nutrition parameters in active CD. MATERIALS AND METHODS: Thirty-eight patients were allocated into 3 groups: group 1 (patients who received only nutrition orientation), group 2 (nutrition orientation and a normoproteic, normocaloric nutrition supplement), and group 3 (nutrition orientation and the nutritional supplement with TGF-ß2). Clinical and nutrition evaluation, C-reactive protein (CRP) levels, and assessment of endoscopic and histologic parameters in the intestinal mucosa were performed before and after nutrition intervention. RESULTS: The mean follow-up period was 3 months. In the beginning of the study, groups were homogeneous regarding age, gender, CD behavior and localization, and medication in use. In the end of the study, the Clinical Disease Activity Index score was reduced in groups 2 and 3; in group 3, a reduction in CRP levels and an improvement in histologic findings were observed. Among patients who received nutritional supplement, some anthropometric patterns were improved. CONCLUSION: The results of the study indicate that nutritional supplementation improved nutrition and inflammatory patterns in patients with active CD. However, only patients receiving TGF-ß2-enriched formula showed improvement in histologic parameters and significant reduction in CRP levels.

The history of quality and safety of the surgical patient: from the initial standards to the present day / Evolução da história da qualidade e segurança do paciente cirúrgico: desde os padrões iniciais até aos dias de hoje

ABSTRACT There are currently various concepts related to quality, which have been implemented by many hospitals and other healthcare institutions. The search for continuous improvement, the implementation of a quality culture and hospital accreditation have also been common, in these institutions. However, the history of hospital audits and accreditation is complex and full of dynamic concepts. The American College of Surgeons was pioneer in publishing, more than a century ago, the first document pertaining quality standards. After that, various programs and concepts have been developed and remodeled by distinct entities. In this article, we briefly review the history of quality in the world and Brazil. We also discuss related concepts regarding its assessment in healthcare.

RESUMO Sólidos conceitos de qualidade assistencial são adotados em grandes hospitais e serviços de saúde da atualidade. A busca por melhoria contínua, implementação de cultura de qualidade e obtenção de selos de certificação em qualidade hospitalar é comum em tais instituições. Entretanto, a história da avaliação hospitalar e do processo de certificação é longa e repleta de conceitos dinâmicos. O "American College of Surgeons" foi pioneiro ao publicar há mais de um século o primeiro documento contendo diretrizes sobre padrões de qualidade a serem seguidos. Posteriormente, múltiplos programas e conceitos foram criados e remodelados por distintas entidades. Neste artigo, apresentamos breve revisão da história da qualidade no mundo e no Brasil, além de alguns conceitos relacionados à avaliação da mesma em saúde.

Safety and quality in surgery: surgeons' perception in Brazil. / Segurança e qualidade em cirurgia: a percepção de cirurgiões no Brasil.

OBJECTIVE: to evaluate the perception of surgeons, members of the Brazilian College of Surgeons (CBC), on safety and quality issues in surgery, based on projects of Brazilian Ministry of Health (MS), CBC, World Health Organization (WHO), and American College of Surgeons (ACS). METHODS: a questionnaire based on WHO, CBC, and ACS initiatives was sent to all active and non-active CBC members, using Survey Monkey, in March 2018. RESULTS: out of 7,100 members, 171 professionals answered the questionnaire. Out of these, the majority (63.2%) declared to perform general surgery, 88.9% indicated knowing the project called Safe Surgery developed by MS, 73.1%, the CBC manual, and 14.6%, the ACS Strong for Surgery. Among those who indicated knowing the MS project, 73.1% said that they were accustomed to use it as a routine, and, among those who indicated knowing the CBC manual, 46.2% said that they were accustomed to use it. Most of the surgeons (81.3%) indicated that they had experienced severe surgical failures, being failures related to surgical material (49.7%) and presence of foreign bodies (8.2%) the most common ones. There were distinct opinions on who was responsible for checking over the checklist. CONCLUSION: the importance of safety and quality in surgery is well known by surgeons, but the practice is varied. Serious adverse events had been experienced by many surgeons, mainly related to surgical material and foreign bodies. The concept of interdisciplinarity did not seem to be common practice. Data indicated the need to develop education projects and the obligation of audits.

OBJETIVO: avaliar a percepção dos cirurgiões, membros do Colégio Brasileiro de Cirurgiões (CBC), sobre temas de segurança e qualidade em cirurgia, com base em Projetos do Ministério da Saúde (MS), do CBC, da Organização Mundial de Saúde (OMS) e do Colégio Americano de Cirurgiões (ACS). MÉTODOS: questionário com base nas iniciativas da OMS, do CBC e do ACS foi enviado pelo Survey Monkey a todos os sócios, ativos e não ativos, do CBC em março de 2018. RESULTADOS: responderam ao questionário 171 profissionais dentre os 7.100 sócios. Desses, a maioria (63,2%) declarou praticar Cirurgia Geral, 88,9% indicaram conhecer o Projeto Cirurgia Segura do MS, 73,1%, o Manual do CBC e 14,6%, o Strong for Surgery do ACS. Entre os que conhecem o Projeto do MS, 73,1% disseram usá-lo como rotina e, entre os que conhecem o Manual do CBC, 46,2% usam-no. A maior parte dos cirurgiões (81,3%) indicou que já vivenciou falha cirúrgica grave, sendo aquelas relacionadas com material cirúrgico (49,7%) e presença de corpos estranhos (8,2%), isoladamente, as mais comuns. Houve opiniões distintas sobre a responsabilidade de conferência do checklist. CONCLUSÃO: a importância da segurança e qualidade em cirurgia é conhecida pelos cirurgiões, mas a prática é variada. Eventos adversos graves foram vivenciados por muitos cirurgiões, principalmente relacionados com material cirúrgico e corpos estranhos. O conceito de interdisciplinaridade parece não ser prática comum. Os dados indicam a necessidade de desenvolver projetos de educação e a obrigatoriedade de auditorias.
