ABSTRACT Objective: To assess the 30-day unplanned readmission rate and its association with overlapping probable sarcopenia and malnutrition after major oncological surgery. Methods: A prospective bicentric observational cohort study performed with adult oncological patients undergoing major surgery. The primary outcome was unplanned readmission within 30 days after discharge and the association with probable sarcopenia and malnutrition. Nutritional status and probable sarcopenia were assessed just prior to surgery. Patients classified using subjective global assessment, as B and C were malnourished. Probable sarcopenia was defined using SARC-F (strength, assistance with walking, rise from a chair, climb stairs, falls) questionnaire ≥4 points and low HGS (handgrip strength) <27kg for males and <16kg for females. Results: Two hundred and thirty-eight patients (51.7% female) with a median age of 60 years were included. The 30-day readmission rate was 9.0% (n=20). Univariate analysis showed an association of malnutrition (odds ratio (OR) = 4.84; p=0.024) and probable sarcopenia (OR = 4.94; p=0.049) with 30-day readmission. Furthermore, when both conditions were present, the patient was almost nine times more likely to be readmitted (OR = 8.9; p=0.017). Multivariable logistic regression analysis showed that overlapping probable sarcopenia and malnutrition was an independent predictor of 30-day unplanned readmission (OR = 8.10, 95% confidence interval (95%CI) 1.20-0.55; p=0.032). Conclusion: The 30-day unplanned readmission rate was 9.0%, and the overlap of probable sarcopenia and malnutrition is an independent predictor for the 30-day unplanned readmission after major oncologic surgery.

RESUMO RACIONAL: O conceito introduzido pelos protocolos de recuperação após a cirurgia modifica os cuidados perioperatórios tradicionais em cirurgia digestiva. A integração desses componentes modernos de recomendações, durante o período perioperatório, é de grande importância para garantir menos complicações pós-operatórias, redução do tempo de internação hospitalar e diminuição dos custos cirúrgicos. OBJETIVOS: Enfatizar os pontos mais importantes de um protocolo multimodal de cuidados perioperatórios. MÉTODOS: Análise criteriosa de cada recomendação dos protocolos ERAS e ACERTO, justificando sua inclusão no atendimento multimodal recomendado para pacientes de cirurgia digestiva. RESULTADOS: Os programas de recuperação avançada (PRAs), tais como os protocolos ERAS e ACERTO, são a base dos cuidados perioperatórios modernos. A terapia nutricional é de grande importância na cirurgia digestiva e, portanto, tanto os cuidados nutricionais pré-operatórios, quanto pós-operatórios são fundamentais para garantir menos complicações pós-operatórias e reduzir o tempo de internação hospitalar. O conceito de pré-habilitação é outro elemento-chave nos PRAs. O manuseio de fluidos cristalóides em perfeito equilíbrio é vital. A sobrecarga de fluidos pode atrasar a recuperação dos pacientes e aumentar as complicações pós-operatórias. A abreviação do jejum pré-operatório para duas horas antes da anestesia é agora aceita por diversas diretrizes das sociedades cirúrgicas e de anestesiologia. Combinadas com a realimentação pós-operatória precoce, essas prescrições não são apenas seguras, mas também podem melhorar a recuperação de pacientes submetidos a procedimentos digestivos. CONCLUSÕES: Este posicionamento do Colégio Brasileiro de Cirurgia Digestiva enfatiza fortemente que a implementação de PRAs em cirurgia digestive, representa uma mudança de paradigma no cuidado perioperatório, transcendendo as práticas tradicionais e adotando uma abordagem inteligente para o bem-estar do paciente.

ABSTRACT OBJECTIVES: To investigate the prevalence of sarcopenia according to five cut-off points for muscle strength and the association with undernutrition in Community dwelling older adults. METHODOLOGY: Cross-sectional study with 321 elderly subjects from community centers in Cuiabá-MT. The main variable was the prevalence of sarcopenia and association with undernutrition. Sarcopenia was diagnosed by low muscle strength (grip strength - GS; kg) according to five cut-off points and low calf circumference (CC; cm). Nutritional status was assessed by mini nutritional assessment-short form (MNA-SF®). RESULTS: The median age was 69 (64-74) years, and 24.7% were undernourished. The presence of sarcopenia ranged from 1.6 to 7.6%. This prevalence was lower using EWGSOP2 criteria compared to EWGSOP (p=0.005) and ESCEO and SDOC criteria (p<0.001). The older undernourished adults were almost 3.5 times more likely to have sarcopenia (OR=3.49; p=0.003) when ESCEO criteria was used and almost 2.5 times (OR=2.43; p=0.037) times using SDOC criteria. CONCLUSIONS: The prevalence of sarcopenia ranged from 1.6 to 7.6%. The older undernourished adults were almost 3.5 (ESCEO) and 2.5 (SDOC) times more likely to have sarcopenia.

The field of medicine has always been at the forefront of technological innovation, constantly seeking new strategies to diagnose, treat, and prevent diseases. Guidelines for clinical practice to orientate medical teams regarding diagnosis, treatment, and prevention measures have increased over the years. The purpose is to gather the most medical knowledge to construct an orientation for practice. Evidence-based guidelines follow several of the main characteristics of a systematic review, including systematic and unbiased search, selection, and extraction of the source of evidence. In recent years, the rapid advancement of artificial intelligence (AI) has provided clinicians and patients with access to personalized, data-driven insights, support and new opportunities for healthcare professionals to improve patient outcomes, increase efficiency, and reduce costs. One of the most exciting developments in AI has been the emergence of chatbots. A chatbot is a computer program to simulate conversation with human users. Recently, OpenAI, a research organization focused on machine learning, developed ChatGPT, a large language model that generates human-like text. ChatGPT uses a type of AI known as a deep learning model. ChatGPT can quickly search and select pieces of evidence through numerous databases to provide answers to complex questions, reducing the time and effort required to research a particular topic manually. Consequently, language models can accelerate the creation of clinical practice guidelines. While there is no doubt that ChatGPT has the potential to revolutionize the way healthcare is delivered, it is essential to note that it should not be used as a substitute for human healthcare professionals. Instead, ChatGPT should be seen as a tool that can be used to augment and support the work of healthcare professionals, helping them to provide better care to their patients.

ABSTRACT BACKGROUND: To reduce the risk of regurgitation during anesthesia for elective procedures, residual gastric volumes (RGV) have traditionally been minimized by overnight fasting. Prolonged preoperative fasting presents some adverse consequences and has been abandoned for most surgical procedures, except for obese and/or diabetic patients. AIMS: The aim of this study was to assess the RGV in morbidly obese diabetic patients after traditional or abbreviated fasting. METHODS: This study was approved by the Ethics Committee for Research with Human Beings from the Federal University of Mato Grosso, under number 179.017/2012. This is a prospective, randomized, and crossover design study in eight morbidly obese type II diabetic patients. RGV was measured endoscopically after either traditional overnight fasting of at least 8 hours, or after abbreviated fasting of 6 hours for solids and 3 hours for a drink containing water plus 25 g (12.5%) of maltodextrin. Data were expressed as mean and range and differences were compared with paired t-tests at p<0.05. RESULTS: The study population had a mean age of 41.5 years (28–53), weight of 135 kg (113–196), body mass index of 48.2 kg/m2 (40–62.4), and type II diabetes for 4.5 years (1–10). The RGV after abbreviated fasting was 21.5 ml (5–40) vs 26.3 ml (7–65) after traditional fasting. This difference was not significant (p=0.82). CONCLUSIONS: Gastric emptying in morbidly obese diabetic patients is similar after either traditional or abbreviated fasting with a carbohydrate drink.

RESUMO RACIONAL: Para reduzir o risco de regurgitação durante a anestesia para procedimentos eletivos, os volumes gástricos residuais (VRG) têm sido tradicionalmente minimizados com jejum noturno. O jejum pré-operatório prolongado tem algumas consequências adversas e tem sido abandonado para a maioria dos procedimentos cirúrgicos, com exceção de pacientes obesos e/ou diabéticos. OBJETIVOS: O objetivo deste estudo foi avaliar o VRG em pacientes diabéticos obesos mórbidos após jejum tradicional ou abreviado. MÉTODOS: Este estudo foi aprovado pelo Comitê de Ética em Pesquisa com Seres Humanos da Universidade Federal de Mato Grosso, sob o número 179.017/2012. Este é um projeto prospectivo, randomizado e cruzado em 8 pacientes diabéticos tipo II com obesidade mórbida. O VRG foi medido endoscopicamente após jejum noturno tradicional (pelo menos 8 horas) ou após jejum abreviado (6 horas para sólidos e 3 horas para uma bebida contendo água mais 25 g (12,5%) de maltodextrina). Os dados são expressos como média e variação e as diferenças foram comparadas com testes t pareados em p<0,05. RESULTADOS: A população estudada tinha 41,5 (28–53) anos de idade, peso médio de 135 (113–196) kg, índice de massa corporal (IMC) de 48,2 (40–62,4) kg/m2 e diabetes tipo II de 4,5 (1–10) anos. O VRG após o jejum abreviado foi de 21,5 (5–40) ml versus 26,3 (7–65) ml após o jejum tradicional. Essa diferença não foi significativa (p=0,82). CONCLUSÕES: O esvaziamento gástrico em pacientes diabéticos obesos mórbidos é semelhante após jejum tradicional ou abreviado com uma bebida com carboidrato.

RESUMO - RACIONAL: Custos hospitalares em cirurgia constituem um peso para o sistema de saúde. Protocolos multimodais como o projeto ACERTO aceleram a recuperação pós-operatória. OBJETIVO: O objetivo deste estudo foi o de analisar custos hospitalares em pacientes submetidos a procedimentos cirúrgicos de grande porte no aparelho digestivo com ou sem as estratégias de cuidados perioperatórios proposta pelo projeto ACERTO. MÉTODOS: Foram coletados dados retrospectivos de pacientes eletivos submetidos a procedimentos cirúrgicos de grande porte no aparelho digestivo em um Hospital Universitário entre Janeiro de 2002 e Dezembro de 2011. O estudo envolveu duas fases: Entre Janeiro de 2002 a Dezembro 2005 envolvendo casos internados antes da implementação do protocolo ACERTO (período pré-ACERTO) e casos operados entre Janeiro de 2006 a Dezembro de 2011, após a implementação (período ACERTO). O desfecho primário foi a comparação de custos hospitalares entre os dois períodos. Como desfechos secundários, comparou-se o tempo de internação (LOS), complicações pós-operatórias, taxa de infecção de sitio cirúrgico (ISS) e a mortalidade. RESULTADOS: Foram analisados 381 pacientes (239 do período pré-ACERTO e 142 do período ACERTO) submetidos a procedimento cirúrgicos de grande porte no trato gastrointestinal. Pacientes operados dentro do protocolo ACERTO apresentaram mediana (IQR) mediana de tempo de internação três dias menor (p=0.001) quando comparados ao período pré-ACERTO (mediana (IQR): 10 (12) vs. 13 (12) dias). A mortalidade foi similar entre os dois períodos. Entretanto, o risco de complicações pós-operatórias foi 29% maior (RR: 1.29; IC95%: 1.11 - 1.50) no período pré-ACERTO (p=0.002). O risco de SSI também foi maior no período pré-ACERTO (RR: 1.33; 95%CI: 1.14-1.50). Custos (media e SE) per paciente foram de R$ 24562,84 (1349,33) antes da implementação e R$ 19912,81 (1459,89) após o protocolo ACERTO (p=0.02). CONCLUSÕES: A implementação do projeto ACERTO neste hospital universitário reduziu custos hospitalares em cirurgias digestivas de grande porte. Além disso, a prescrição de estratégias modernas de cuidados perioperatórios também reduziu riscos de complicações pós-operatórias e de SSI e o tempo de internação.

ABSTRACT - BACKGROUND: Hospital costs in surgery constitute a burden for the health system in all over the world. Multimodal protocols such as the ACERTO project enhance postoperative recovery. OBJECTIVE: The aim of this study was to analyze the hospital costs in patients undergoing major digestive surgical procedures with or without the perioperative care strategies proposed by the ACERTO project. METHODS: Retrospective data from elective patients undergoing major digestive surgical procedures in a university hospital between January 2002 and December 2011 were collected. The investigation involved two phases: between January 2002 and December 2005, covering cases admitted before the implementation of the ACERTO protocol (pre-ACERTO period), and cases operated between January 2006 and December 2011, after implementation (ACERTO period). The primary outcome was the comparison of hospital costs between the two periods. As secondary end point, we compared length of stay (LOS), postoperative complications, surgical-site infection (SSI) rate, and mortality. RESULTS: We analyzed 381 patients (239 of the pre-ACERTO period and 142 of the ACERTO period) who underwent major procedures on the gastrointestinal tract. Patients operated after within the ACERTO protocol postoperative LOS had a median of 3 days shorter (p=0.001) when compared with pre-ACERTO period [median (IQR): 10 (12) days vs. 13 (12) days]. Mortality was similar between the two periods. Postoperative complications risk, however, was 29% greater (RR: 1.29; 95%CI 1.11-1.50) in the pre-ACERTO period (p=0.002). SSI risk was also greater in pre-ACERTO period (RR: 1.33; 95%CI 1.14-1.50). Costs (mean and SE) per patients were R$24,562.84 (1,349.33) before the implementation and R$19,912.81 (1,459.89) after the ACERTO protocol (p=0.02). CONCLUSION: The implementation of the ACERTO project in this University Hospital reduced the hospital costs in major digestive procedures. Moreover, the implementation of this modern perioperative care strategy also reduced postoperative complications, SSI risks, and LOS.

ABSTRACT Background: The allogeneic transfusion-related immunomodulation (TRIM) may be responsible for an increase in survival of renal transplants but in contrast it could increase the rate of bacterial infections or the recurrence rate of tumors post-operatively. Objective: This review focuses in the implications of perioperative allogeneic transfusions on the immune-inflammatory response of surgical transfused patients. Results: ABTs modify immune functions in recipients including decrease of the number of lymphocytes; decrease the CD4 cells; decrease the CD4/CD8 T-cell ratio; decrease NK cells; and decrease the lymphocyte response to mitogens. TRIM effects may be mediated by allogeneic white cells present in blood products; soluble peptides present in transfused plasma; and/or biologic mediators released into the supernatant of blood units. A recent systematic review and meta-analysis including 36 clinical observational studies (n = 174,036) concluded that perioperative ABTs not only decreased overall survival and reduced colorectal cancer-specific survival. Furthermore ABTs increased the rate of infectious, cardiac, pulmonary and anastomotic complications in colorectal cancer patients undergoing surgery. Conclusions: It has been demonstrated by laboratory tests that TRIM is associated with transfusion recipient immune alterations but its influence in colorectal cancer recurrence after resection remains controversial though may exist. Surgical techniques reducing intraoperative blood loss have limited the number of ABTs perioperatively, however increase in mortality continues to be reported in literature after ABT in colorectal cancer surgery. Poor survival associated to TRIM in colorectal cancer might be due to higher number of allogeneic transfused units and/or prolonged length of blood storage.

RESUMO OBJETIVO: Determinar a frequência de hipofosfatemia como marcador da síndrome de realimentação (SR) antes e após o início da TN em pacientes críticos. MÉTODOS: Coorte retrospectiva realizada com 917 pacientes adultos de um hospital terciário em Cuiabá-MT. Foi determinada a frequência de hipofosfatemia (fósforo <2,5 mg/dl) como marcador de risco de SR, para valores de fósforo sérico da admissão (P1) e após o início da TN (P2). RESULTADOS: Foi observado um aumento significativo (36,3%) da hipofosfatemia entre P1 e P2 e, consequentemente, do risco de SR (25,6% vs 34,9%; p<0,001) com o início da TN. Após o início da TN, pacientes desnutridos apresentaram maior queda do fósforo sérico. Os pacientes com TN apresentaram aproximadamente 1,5 vez mais chance de desenvolver hipofosfatemia e risco de SR (OR=1,44 IC95% 1,10-1,89; p=0,01) quando comparado aos com dieta oral. Nutrição parenteral foi mais associada à hipofosfatemia versus nutrição enteral (p=0,001) e nutrição enteral suplementada com parenteral (p=0,002). CONCLUSÃO: A frequência de pacientes críticos com hipofosfatemia e em risco de SR é alta e esse risco aumenta após o início da TN, especialmente nos desnutridos e naqueles recebendo nutrição parenteral.

Summary OBJECTIVE: To investigate the prevalence of hypophosphatemia as a marker of refeeding syndrome (RFS) before and after the start of nutritional therapy (NT) in critically ill patients. METHODS: Retrospective cohort study including 917 adult patients admitted at the intensive care unit (ICU) of a tertiary hospital in Cuiabá-MT/Brasil. We assessed the frequency of hypophosphatemia (phosphorus <2.5mg/dl) as a risk marker for RFS. Serum phosphorus levels were measured and compared at admission (P1) and after the start of NT (P2). RESULTS: We observed a significant increase (36.3%) of hypophosphatemia and, consequently, a greater risk of RFS from P1 to P2 (25.6 vs 34.9%; p<0.001). After the start of NT, malnourished patients had a greater fall of serum phosphorus. Patients receiving NT had an approximately 1.5 times greater risk of developing RFS (OR= 1.44 95%CI 1.10-1,89; p= 0.01) when compared to those who received an oral diet. Parenteral nutrition was more associated with hypophosphatemia than either enteral nutrition (p=0,001) or parenteral nutrition supplemented with enteral nutrition (p=0,002). CONCLUSION: The frequency of critically ill patients with hypophosphatemia and at risk for RFS on admission is high and this risk increases after the start of NT, especially in malnourished patients and those receiving parenteral nutrition.

Abstract Background: the management of patients with enterocutaneous fistula (ECF) requires an interdisciplinary approach and poses a significant challenge to surgeons, gastroenterologists, intensivists, wound/stoma care specialists, and nutrition support clinicians. Available guidelines for optimizing nutritional status in these patients are often vague, based on limited and dated clinical studies, and typically rely on individual or institutional experience. Specific nutrient requirements, appropriate route of feeding, role of immune-enhancing nutrients, and use of somatostatin analogs in the management of patients with ECF remain a challenge for the clinician. The purpose of this clinical guideline is to develop recommendations for the nutritional care of adult patients with ECF. Methods: a systematic review of the best available evidence to answer a series of questions regarding clinical management of adults with ECF was undertaken and evaluated using concepts adopted from the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) Working Group. An anonymous consensus process was used to develop the clinical guideline recommendations prior to peer review and approval by the A.S.P.E.N. and FELANPE Board of Directors. Questions: in adult patients with enterocutaneous fistula: 1) What factors best describe nutritional status? 2) What is the preferred route of nutritional therapy (oral diet, EN or PN)? 3) What protein and energy intake provide best clinical outcomes? 4) Is fistuloclysis associated with better outcomes than standard care? 5) Are immune-enhancing nutrients associated with better outcomes? 6) Does the use of somatostatin provide better outcomes than standard medical therapy? 7) When is home parenteral nutrition support indicated?

Resumen Introducción: el manejo de las fístulas enterocutáneas (FEC) es un reto que requiere un enfoque interdisciplinario y plantea un desafío importante. Las guías para optimizar el estado nutricional en estos pacientes están basadas en estudios que dependen de la experiencia individual y, ocasionalmente, institucional; que se focalizan en el tratamiento integral de las FEC, centrándose en el manejo médico y quirúrgico, mientras que la terapia nutricional se revisa solo superficialmente. Los requerimientos nutricionales, la vía de administración, el uso de inmunonutrición y el de análogos de la somatostatina en el tratamiento de estos pacientes no están bien definidos. El objetivo de esta guía clínica es desarrollar recomendaciones específicas para la terapia nutricional de los pacientes adultos con FEC. Método: revisión sistemática de la mejor evidencia disponible para responder a una serie de preguntas sobre la terapia nutricional de los adultos con FEC, evaluada utilizando la metodología GRADE. Se utilizó un proceso de consenso anónimo para desarrollar las recomendaciones de la guía clínica antes de la revisión por pares y la aprobación por las Juntas Directivas de ASPEN y FELANPE. Preguntas: 1) ¿Qué factores describen mejor el estado nutricional de los adultos con FEC? 2) ¿Cuál es la mejor vía para administrar la terapia nutricional (oral, nutrición enteral o parenteral)? 3) ¿Qué aporte energético y proteico proporciona mejores resultados clínicos? 4) ¿El uso de la fistuloclisis se asocia a mejores resultados? 5) ¿Las fórmulas inmunomoduladoras se asocian a mejores resultados? 6) ¿El uso de la somatostatina proporciona mejores resultados? 7) ¿Cuándo está indicada la terapia nutricional parenteral domiciliaria?

RESUMO Objetivo: avaliar o impacto da provável sarcopenia (PS) pré-operatória na sobrevida de pacientes oncológicos submetidos a operações de grande porte. Métodos: estudo bicêntrico de coorte prospectivo, realizado com pacientes oncológicos adultos, submetidos a operação de grande porte no Hospital de Câncer e na Santa Casa de Misericórdia em Cuiabá-MT. A variável principal foi a ocorrência de óbito pós-operatório. Coletou-se dados demográficos, clínicos e o diagnóstico de PS, definido pela presença de: 1) risco de sarcopenia pelo questionário SARC-F e 2) baixa força muscular (Kgf) mensurada pela dinamometria. Calculou-se a taxa de sobrevida acumulada para os pacientes com e sem PS pela curva de Kaplan-Meier. Aplicou-se o modelo de regressão de Cox uni e multivariado para avaliar a associação da mortalidade com covariáveis de confundimento investigadas. Resultados: participaram do estudo 220 pacientes com idade média (DP) de 58,7±14,0 anos, sendo 60,5% do sexo masculino. Quatorze (6,4%) pacientes foram considerados com PS. Os pacientes com PS apresentaram risco aumentado para a ocorrência de óbito (RR=5,35 IC95% 1,95-14,66; p=0,001) e para complicações infecciosas (RR=2,45 IC95% 1,12-5,33; p=0,036). A sobrevida média em 60 dias, foi menor para os pacientes com PS: 44 (IIQ=32-37) vs 58 (IIQ=56-59) dias (log rank <0,001). A regressão Multivariada de Cox, mostrou que a PS foi fator de risco independente (HR=5,8 IC95% 1,49-22,58; p=0,011) para a mortalidade. Conclusão: os pacientes com PS submetidos a operações oncológicas de grande porte apresentam menor probabilidade de sobrevida a curto prazo e a PS pré-operatória, é fator de risco independente para mortalidade pós-operatória.

ABSTRACT Objective: to evaluate the impact of probable sarcopenia (PS) on the survival of oncological patients submitted to major surgeries. Method: prospective cohort bicentrical study enrolling adult oncological patients submitted to major surgeries at Cancer Hospital and Santa Casa de Misericordia in Cuiabá-MT. The main endpoint was the verification of postoperative death. Demographic and clinical data was collected. PS was defined as the presence of 1) sarcopenia risk assessed by SARC-F questionnaire and 2) low muscle strength measured by dynamometry. The cumulative mortality rate was calculated for patients with either PS or non PS using Kaplan Meier curve. The univariate and multivariate Cox regression model was used to evaluate the association of mortality with various investigated confounding variables. Results: a total of 220 patients with a mean (SD) age of 58.7±14.0 years old, 60.5% males participated of the study. Patients with PS had higher risk to postoperative death (RR=5.35 95%CI 1.95-14.66; p=0,001) and for infectious complications (RR=2.45 95%CI 1.12-5.33; p=0.036). The 60 days mean survival was shorter for patients with PS: 44 (IQR=32-37) vs 58 (IQR=56-59) days (log rank <0,001). The Cox multivariate regression showed that PS was an independent risk factor (HR=5.8 95%CI 1.49-22.58; p=0.011) for mortality. Conclusion: patients bearing PS submitted to major oncological surgery have less probability of short term survival and preoperative PS is an independent risk for postoperative mortality.

RESUMO Objetivo: investigar o impacto de procedimentos cirúrgicos oncológicos na função muscular de pacientes com e sem risco nutricional. Métodos: estudo observacional realizado com pacientes oncológicos candidatos a operações de grande porte entre julho de 2018 a março de 2019 em Cuiabá, Mato Grosso, Brasil. Os pacientes foram avaliados no pré-operatório quanto ao risco nutricional pela Nutricional Risk Screening-2002 e avaliou-se a força de preensão palmar (FPP) tanto no pré- quanto no 2º e 5º dia de pós-operatório (PO). Resultados: Foram avaliados 92 pacientes, dos quais 55,4% eram homens e 44,6% mulheres, com média (DP) de idade de 64 (10,81) para pacientes com risco e 51 (12,99) para pacientes sem risco nutricional. A avaliação nutricional pré-operatória mostrou que 34,8% dos pacientes não tinham risco e 65,2% apresentavam risco nutricional. A FPP foi menor (p=0,008) no grupo com risco nutricional no pré-operatório. Em ambos os grupos houve queda significativa da FPP no 2º dia de PO. A queda da FPP do pré-operatório para o 2º dia de PO foi mais pronunciada em pacientes sem risco nutricional (p=0,039). Pacientes com risco nutricional apresentaram maior tempo de internação (p=0,049). Conclusão: O trauma cirúrgico acarreta perda da função muscular no PO precoce. Pacientes sem risco nutricional apresentam queda da força muscular mais expressiva após procedimentos cirúrgicos oncológicos do que aqueles com risco nutricional. Esses resultados servem como argumento bastante forte para a implementação da Pré-habilitação em todos os pacientes candidatos a operações oncológicas de grande porte.

ABSTRACT Objectives : to investigate the impact of oncological surgical procedures on the muscle function of patients with and without nutritional risk. Methods: cross-sectional study conducted with cancer patients undergoing major operations between July 2018 to March 2019 in Cuiabá, Mato Grosso, Brazil. Patients were assessed preoperatively for the nutritional risk by the Nutricional Risk Screening-2002, and handgrip strength (FPP) was assessed both on the pre- and 2nd and 5th postoperative days (PO). Results: 92 patients were evaluated, of whom 55.4% were men and 44.6% women, with a mean age (SD) of 64 (10.81) for patients at risk and 51 (12.99) for patients without nutritional risk. The preoperative nutritional risk evaluation indicated that 34.8% of the patients had no risk and 65.2% had a nutritional risk. The FPP was lower (p = 0.008) in the group with nutritional risk in the preoperative period. In both groups, there was a significant drop in FPP on the 2nd PO day. The preoperative FPP compared with the 2nd PO FPP was more pronounced in patients without nutritional risk (p = 0.039). Patients with nutritional risk had a longer hospital stay (p = 0.049). Conclusion: surgical trauma causes loss of muscle function in the early PO. Patients without nutritional risk have a more significant decrease in muscle strength after surgical oncological procedures than those with nutritional risk. These results may infer the need to implement pre-habilitation in all patients who will undergo major oncological procedures.
