Age-adjusted Charlson comorbidity index and its association with body composition and overall survival in patients with colorectal cancer.

OBJECTIVE: To examine the relationship between the age-adjusted Charlson comorbidity index (A-CCI) with body composition and overall survival in patients newly diagnosed with colorectal cancer (CRC). RESEARCH METHODS AND PROCEDURES: In this cohort study, patients (≥ 18 years old) with CRC were followed for 36 months. Computed tomography images of the third lumbar were analyzed to determine body composition, including skeletal muscle area (SMA), skeletal muscle index (SMI), skeletal muscle radiodensity (SMD), visceral adipose tissue (VAT), and subcutaneous adipose tissue (SAT). Phenotypes based on comorbidity burden assessed by A-CCI and body composition parameters were established. RESULTS: A total of 436 participants were included, 50% male, with a mean age of 61 ± 13.2 years. Approximately half of the patients (50.4%) had no comorbidity, and the A-CCI median score was 4 (interquartile range: 3-6). A higher A-CCI score was a risk factor for 36-month mortality (HR = 3.59, 95% CI = 2.17-5.95). Low SMA and low SMD were associated with a higher A-CCI. All abnormal phenotypes (high A-CCI and low SMA; high A-CCI and low SMD; high A-CCI and high VAT) were independently associated with higher 36-month mortality hazard (adjusted HR 5.12, 95% CI 2.73-9.57; adjusted HR 4.58, 95% CI 2.37-8.85; and adjusted HR 2.36, 95% CI 1.07-5.22, respectively). CONCLUSION: The coexistence of comorbidity burden and abnormal body composition phenotypes, such as alterations in muscle or fat compartments, may pose an additional risk of mortality in patients newly diagnosed with CRC. Early assessment and management of these phenotypes could be crucial in optimizing outcomes in such patients.

Relationship between Sarcopenia and mTOR Pathway in Patients with Colorectal Cancer: Preliminary Report.

Sarcopenia is a syndrome characterized by loss of muscle mass and strength that impacts clinical outcomes and mortality in cancer patients. Although the molecular pathways involved in sarcopenia are not fully elucidated, the decrease in protein synthesis rate appears to be one of the most important events. The objective of this study was to investigate the relationship between sarcopenia and mTOR signaling pathway in patients undergoing colorectal resection surgery. Three groups of patients were assessed: 1) the control group (no cancer, no sarcopenia), 2) the cancer non-sarcopenic group and 3) the cancer sarcopenic group. All individuals were evaluated in relation to presence of sarcopenia and mTOR signaling pathway. Sarcopenia was evaluated by the combination of low muscle mass and low muscle strength, measured using computerized tomography images, and hand grip strength, respectively. Rectus abdominis muscle biopsy was performed at the time of surgery. mTOR pathway was analyzed by MILLIPLEX Map Kit Phospho/total mTOR 2-Plex Magnetic Bead Panel. Results were presented by phosphor/total mTOR ratio. Independent T test, Kruskal-Wallis test, and Dunn-Bonferroni post hoc were performed for statistical analysis and P < 0.05 was considered. Thirty-six patients and five controls were evaluated. A total of 13 cancer patients (36.1%) had sarcopenia. The phospho/total mTOR ratio was different between the control group (0.167 MFI) and the cancer non-sarcopenic group (0.055 MFI) (P = 0.026) as well as between the control group (0.167 MFI) and the cancer sarcopenic group (0.0049 MFI) (P = 0.041). No difference was observed on the median phospho/total mTOR ratio between the cancer groups (P > 0.05). More research is needed to extrapolate these results.

Nutritional Status Parameters as Risk Factors for Mortality in Cancer Patients.

The aim of this study was to verify the relationship between weight loss, handgrip strength (HGS) and phase angle (PA) before the beginning of chemotherapy with overall survival in cancer patients. Patients diagnosed with gastrointestinal and breast cancer who were over 18 years old and were scheduled to undergo adjuvant treatment at Hospital Borges da Costa/Brazil were evaluated. The exclusion criteria were neoadjuvant treatment, patients with kidney and liver disease and using diuretics. Weight, HGS and PA tests were performed by trained dietitians. The Kaplan-Meier survival method and the log-rank test, cox regression and ROC curve were used and p < 0.05 was considered significant. Two-hundred and twenty-eight patients were evaluated.The median survival time was higher among the patients who showed weight loss of less than 10% of usual body weight (p < 0.05). Regarding HGS, patients with decreased HGS had a 22.0 month survival versus 34.2 months for those with normal values (p < 0.05). 146 patients had normal PA values, and these patients had increased survival time compared to those with inappropriate values (p < 0.05). In the Cox regression, weight loss and PA were predictors of mortality, HGS wasn't significantly associated with mortality. ROC analysis revealed that weight loss was the nutritional status parameter with the most predictive power.

Use of neutropenic diet in the nutritional care of pediatric cancer patients with neutropenia: a scoping review.

OBJECTIVE: to carry out a scoping review with the purpose of mapping the scientific evidence on the use of the neutropenic diet in neutropenic pediatric cancer patients. SOURCE OF DATA: The scoping review protocol was prepared in accordance with the PRISMA-ScR and the checklist before the literature search was performed. Articles on nutritional management in adults or on the treatment of other diseases, and articles that were not in Portuguese or English and published before the year 2000, were excluded. Data were extracted based on the Cochrane Consumer and Communication Review Group form. SUMMARY OF THE FINDINGS: Three hundred and forty scientific articles were identified, with the final sample of this review consisting of nine studies. Although the neutropenic diet has been part of the nutritional management of pediatric cancer patients for more than 20 years, there is still great variation in the criteria for indicating use and starting and discontinuing it, as well as in the nutritional composition of the diet. Furthermore, there is no consensus on the impact of using a neutropenic diet on different clinical and nutritional outcomes. CONCLUSION: In the absence of guidelines that standardize the use of a neutropenic diet in pediatric patients with neutropenia, there are heterogeneous approaches reported in the literature, even within the same institution. The available literature presents an absence of evidence on the use, viability, and effectiveness of the neutropenic diet in oncological children with neutropenia. More studies are needed to identify the real impact of the neutropenic diet on clinical and nutritional outcomes.

Strength-to-muscle radiodensity: A potential new index for muscle quality.

BACKGROUND & AIMS: Although it is widely recognized that muscle quality significantly influences adverse outcomes in patients with cancer, the precise definition of muscle quality remains elusive. The muscle quality index (MQI), also known as muscle-specific strength, is a relatively recent functional concept of muscle quality. It is obtained through the ratio of muscle strength to muscle mass, but its predictive value in patients with cancer remains unknown. In this study, we explored the prognostic significance of MQI in patients with cancer. Furthermore, we introduce and assess the prognostic potential of a novel muscle quality metric: the strength-to-muscle-radiodensity index (SMRi). METHODS: A secondary analysis was conducted on a prospective cohort study. CT scans were opportunistically used to assess body composition parameters, including skeletal muscle mass (SM in cm2) and muscle radiodensity (SMD in HU) at the third lumbar vertebra (L3). Handgrip strength (HGS) was measured. MQICT was calculated using the ratio of HGS to SM (cm2). SMRi was calculated as the ratio of HGS to SMD (HU). For analysis purposes, low MQICT and SMRi were defined using two approaches: statistical cutoffs associated with survival, and median-based distribution data. RESULTS: A total of 250 patients were included (52.8% females, 52% adults, 20-90 years). Gastrointestinal tumors and stage III-IV were the most frequent diagnosis and stages. SMRi and MQICT were strongly positively correlated (ρ = 0.71 P < 0.001). Individual components of MQICT and SMRi were also positively correlated. Patients with both low MQICT and SMRi had shorter survival (log-rank P = 0.023 and P = 0.003, respectively). When applying median distribution cutoffs, SMRi emerged as the most accurate predictor of mortality (HR adjusted 3.18, 95% CI 1.50 to 6.75, C-index: 0.71), when compared to MQICT (HR adjusted 1.49, 95% CI 0.77 to 2.87, C-index: 0.68). CONCLUSION: This study introduces the concept and potential prognostic significance of the SMRi. The physiological and clinical implications of this new index warrant further investigation across a spectrum of diseases, including cancer.

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.

The relationship between nutritional status and the Glasgow prognostic score in patients with cancer of the esophagus and stomach.

A relationship between weight loss and inflammation has been described in patients with cancer. In the present study, the relationship between subjective global assessment (SGA) and the severity of inflammation, as defined by Glasgow prognostic score (GPS), as well as the relationship of both of these measures with the presence of complications and survival time, was assessed. In addition, we compared the diagnosis given by SGA with parameters of nutritional assessment, such as body mass index, triceps skinfold, midarm circumference (MAC), midarm muscle circumference (MAMC), phase angle (PA), adductor pollicis muscle thickness (APMT), and handgrip strength (HGS). According to the SGA, the nutritional status was associated with the GPS (P < 0.05), and both the SGA and GPS were associated with the presence of complications. However, the GPS [area under the curve (AUC): 0.77, P < 0.05, confidence interval (CI) = 0.580, 0.956] seems to be more accurate in identifying complications than the SGA (AUC: 0.679, P < 0.05, CI = 0.426, 0.931). Only GPS was associated with survival time. Comparing the different nutritional assessment methods with the SGA suggested that the MAC, MAMC, APMT, PA, and HGS parameters may be helpful in differentiating between nourished and malnourished patients, if new cutoffs are adopted.

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.

Nutritional management of muscle mass loss in patients with Post-COVID-19 Syndrome: a scoping review / Manejo nutricional na perda de massa muscular em pacientes com a Síndrome Pós-COVID-19: uma revisão de escopo

Post-Covid-19 Syndrome (PCS) is a condition that causes persistent symptoms and impacts nutritional status such as loss of muscle mass. The objective of this study was to review and map scientific evidence on nutritional management in the loss of muscle mass in patients with PCS. The scoping review protocol was prepared following the PRISMA-ScR guidelines. Review articles not written in English or those that included only hospitalized patients and pertained to conditions other than PCS were excluded. Data extraction followed the methodology outlined by the Cochrane Review Group. Of the 81 articles initially identified, only five met the inclusion criteria. The selected studies emphasized the importance of recovering muscle mass, higher protein and caloric intake, and physical strength exercises. Consequently, nutritional interventions aimed at mitigating muscle mass loss should prioritize strategies that increase caloric and protein consumption.

A Síndrome Pós-covid-19 (SPC) é uma condição que acarreta sintomas persistentes e impactam o estado nutricional, como a perda de massa. O objetivo deste estudo foi realizar revisão para mapear evidências científicas acerca do manejo nutricional na perda de massa muscular em pacientes com SPC. O protocolo da revisão de escopo foi elaborado de acordo com o PRISMA-ScR. Foram excluídos artigos de revisão que não estivessem em inglês ou português, que incluíssem apenas pacientes hospitalizados e com outras condições que não a SPC. Os dados foram extraídos com base no Cochrane Review Group. 81 artigos foram identificados e a amostra final incluiu cinco estudos. Para a recuperação da massa muscular, maior ingestão proteica, calórica e exercícios físicos de força foram descritos nos estudos. A intervenção nutricional para recuperar a perda de massa muscular deve considerar estratégias que visam o aumento do consumo calórico e proteico.

Different nutritional assessment tools as predictors of postoperative complications in patients undergoing colorectal cancer resection.

BACKGROUND & AIMS: Malnutrition in patients with colorectal cancer contributes to increased postoperative complications. The aim of the study was to evaluate the prognostic value of several nutritional assessment parameters: body mass index versus percentage of weight loss grading system (BMI/%WL); Patient-Generated Subjective Global Assessment (PG-SGA); standardized phase angle (SPA) by BIA; muscle strength by handgrip strength; muscle mass by computerized tomography; and the combination of muscle mass and strength in patients undergoing resection surgery. METHODS: Patients diagnosed with cancer of the colon or rectum, who were over 18 years old and were scheduled to undergo surgical treatment were invited to participate. Postoperative complications were assessed from the first day post-surgery until discharge. Complications classified as Grade II or above according to the Clavien-Dindo classification were considered. Chi-square test or Fisher's exact test, bivariate analysis, Poisson regression and receiver operator characteristic (ROC) curve were utilized and p < 0.05 was considered significant. RESULTS: 84 patients were evaluated, with 28 (33.3%) presenting with Grade II postoperative complications. SPA showed no association with postoperative complications (p = 0.199). In multivariate analysis, low skeletal muscle mass showed a relative risk (RR) of 1.80 (CI: 1.02-3.17), BMI/%WL equal or higher than grade 3 had a RR of 1.90 (95% CI: 1.22-3.39). PG-SGA classified as malnutrition showed a RR of 2.08 (95% CI: 1.06-4.06); and low muscle mass plus low muscle strength showed a RR 2.13 (95% CI: 1.23-3.69). Low strength alone was not associated with postoperative complications after controlling for confounding factors (p = 0.16; 95% CI: 0.83-2.77). Low muscle mass in combination with low strength showed the highest predictive power for postoperative complications (AUC: 0.68; CI: 0.56-0.80). CONCLUSIONS: BMI/%WL > grade 3, PG-SGA defined malnutrition, low muscle mass and low muscle mass plus low strength were independent risk factors for complications controlling for confounding factors. However, low muscle mass in combination with low muscle strength were the strongest variables associated with complications. CLINICAL TRIALS IDENTIFICATION NUMBER: NCT02901132 (www.clinicaltrials.gov).

Combined nutritional assessment methods to predict clinical outcomes in patients on the waiting list for liver transplantation.

OBJECTIVES: Nutritional diagnosis is essential given that malnutrition negatively affects morbidity and mortality in patients with liver disease. In the absence of a standard method, limited accuracy has been reported in relation to nutritional assessment. The aim of the study was to evaluate the use of subjective global assessment (SGA) and different methods of nutritional assessment, isolated and in combination with SGA to predict clinical outcomes. METHODS: This was a longitudinal study with patients waiting for liver transplantation. Nutritional status was classified according to SGA. Anthropometric parameters, standard phase angle (SPA), handgrip strength, and 6-min walk test (6MWT) were evaluated. Univariate and multivariate analysis and receiver operator characteristic curve were performed. P < 0.05 was statistically significant. RESULTS: Seventy-three patients with an average age of 52.3 ± 11.4 y were evaluated. Of these, 63% were men. Low midarm muscle area (MAMA; P < 0.001), malnutrition by SGA + low MAMA (P < 0.001), and malnutrition by SGA + low SPA (P < 0.001) were independent predictors of clinical features of advanced cirrhosis. SGA + SPA presented the greater area under the curve (AUC: 0.6431). Death was predicted by low midarm circumference (MAC; P = 0.037) and slow gait speed on the 6MWT (GS-6MWT; P = 0.017), with both parameters isolated or concomitantly linked to malnutrition. SGA + GS-6MWT presented the highest predictive power for death (AUC: 0.6673) slightly greater than SGA+MAC (AUC: 0.6346). CONCLUSION: The results indicate that SGA together with SPA has greater predictive power for features of advanced cirrhosis, and SGA plus gait speed is able to better predict mortality in patients on the waiting list for liver transplant.

Nutritional and metabolic status of breast cancer women.

INTRODUCTION: The nutritional and metabolic status have been related to cancer risk factors as well as to cancer treatment morbimortality. Thus, its assessment is important for developing strategies for the promotion, maintenance and / or recovery of nutritional status and cancer outcome. MATERIAL AND METHODS: Several different methods for nutritional assessment in breast cancer patients undergoing adjuvant therapy were used, including subjective global assessment (SGA), body mass index (BMI), triceps skinfold (TSF), mid-arm circumference (MAC), adductor pollicis muscle thickness (APMT), hand grip strength (HGS) and bioelectrical impedance analysis (BIA). The presence of metabolic syndrome (MetS) was also evaluated. The occurrence of complications during cancer treatment versus the nutritional status was assessed. RESULTS: We followed 78 women with a mean age of 53.2 } 11.6 years. Most patients were considered well nourished (80.8%). Excessive body fat mass by BIA and MetS were found in 80,8 % and 41.9% of the patients respectively. There were significant differences in BMI, TSF, WC (waist circumference) and % fat mass between patients with and without MetS. Most patients experienced complications during cancer treatment, but there was no association with nutritional or metabolic status. CONCLUSION: In breast cancer women undergoing adjuvant therapy, the prevalence of metabolic syndrome was high and, on the contrary, undernutrition was low. There were no short-term effects of metabolic syndrome or undernutrition on clinical outcomes.

Introducción: El estado nutricional y metabolico se han relacionado con factores de riesgo del cancer, asi como la morbimortalidad del tratamiento del cancer. Por lo tanto, su evaluacion es importante para el desarrollo de estrategias para la promocion, mantenimiento y/o recuperacion del estado nutricional y la evolucion del cancer. Material y métodos: Se utilizaron varios metodos diferentes para la evaluacion nutricional en pacientes con cancer de mama sometidas a terapia adyuvante, incluyendo la valoracion subjetiva global (SGA), el indice de masa corporal (IMC), pliegue tricipital (PT), la circunferencia del brazo (CB), del espesor del musculo aductor del pulgar (TAPM), la fuerza de prension manual (FPM) y el porcentaje de masa grasa (PMG) mediante impedancia bioelectrica. Tambien se evaluo la presencia del sindrome metabolico (SM). Se evaluo la aparicion de complicaciones durante el tratamiento del cancer en comparacion con el estado nutricional. Resultados: Se siguieron a 78 mujeres con una edad media de 53,2 } 11,6 anos. La mayoria de los pacientes estaban bien nutridos (80,8 %). Excesiva PMG y los SM se encontraron en 80,8 % y 41,9 % de los pacientes, respectivamente. Hubo diferencias significativas en el IMC, PT, circunferencia de la cintura y la PMG entre los pacientes con y sin sindrome metabolico. La mayoria de los pacientes experimentaron complicaciones durante el tratamiento del cancer, pero no hubo asociacion con el estado nutricional o metabolico. Conclusión: En las mujeres con cancer de mama que reciben terapia adyuvante, la prevalencia del sindrome metabolico fue alta y, por el contrario, la desnutricion era baja. No hubo efectos a corto plazo del sindrome metabolico o la desnutricion en los resultados clinicos.

Relationship between nutritional status and the Glasgow Prognostic Score in patients with colorectal cancer.

OBJECTIVE: The association between nutritional status and inflammation was assessed in patients with colorectal cancer and to verify their association with complications during anticancer treatment. The agreement between the Subjective Global Assessment (SGA) and different nutritional assessment methods was also evaluated. METHODS: A cross-sectional, prospective, and descriptive study was performed. The nutritional status was defined by the SGA and the severity of inflammation was defined by the Glasgow Prognostic Score (GPS). The complications were classified using the Common Toxicity Criteria, version 3. Anthropometric measurements such as body mass index, triceps skinfold, midarm circumference, midarm muscle area, and adductor pollicis muscle thickness were also performed, as were handgrip strength and phase angle. The chi-square test, Fisher exact test, Spearman correlation coefficient, independent t test, analysis of variance, Gabriel test, and κ index were used for the statistical analysis. P < 0.05 was considered statistically significant. RESULTS: Seventy patients with colorectal cancer (60.4 ± 14.3 y old) were included. The nutritional status according to the SGA was associated with the GPS (P < 0.05), but the SGA and GPS were not related to the presence of complications. When comparing the different nutritional assessment methods with the SGA, there were statistically significant differences. CONCLUSION: Malnutrition is highly prevalent in patients with colorectal cancer. The nutritional status was associated with the GPS.
