Association between functional aspects and health-related quality of life in patients with colorectal cancer: can handgrip strength be the measure of choice in clinical practice?

PURPOSE: We aimed to investigate the association between handgrip strength (HGS) and health-related quality of life (HRQoL) in patients with colorectal cancer (CRC). A cross-sectional study was conducted including CRC patients. METHODS: We performed an assessment of aspects of functional health using the criteria of frailty phenotype (defined by Fried et al., 2001), sarcopenia (defined by the European Working Group on Sarcopenia in Older People 2, 2018) and by HGS, which measures muscle strength using a manual dynamometer. HRQoL was assessed using the EORTC questionnaire QLQ-C30. Analyses of variance and multivariate linear regression were used to compare frailty, sarcopenia, and HGS with HRQoL. RESULTS: A total of 142 patients were included (age 62.7 ± 11.4 years; 56.3% women; 18.3% of patients with frailty; 9.9% with sarcopenia, and 15.5% had low HGS). After adjusting for sociodemographic, clinical, and nutritional variables, the regression analysis showed that frailty and sarcopenia were associated with worse HRQoL. Low HGS was associated with worse HRQoL in patients with CRC regardless of both frailty components (global health status: B = - 13.4, p = 0.004; physical function: B = - 10.4, p = 0.006; emotional function: B = - 18.1, p = 0.041; fatigue: B = 9.1, p = 0.027; dyspnea: B = 10.7, p = p = 0.024; appetite loss: B = 12.4, p = 0.041) and sarcopenia components (global health status: B = - 13.2, p = 0.004; physical function: B = - 15.0, p = 0.001; emotional function: B = - 25.1, p = 0.006; fatigue: B = 15.2, p = 0.007; pain: B = 18.7, p = 0.024, dyspnea: B = 11.4, p = 0.017). CONCLUSION: We concluded that HGS was positively associated with HRQoL in patients with CRC and may initially be the variable of choice in clinical practice, which is associated with HRQoL.

Nutritional status at hospital admission and prediction of clinical outcomes in children and adolescents with cancer: Results of the Brazilian survey on oncological nutrition in paediatrics.

BACKGROUND: Changes in nutritional status are recognised as predictors of unfavourable outcomes in children and adolescents with cancer, particularly in developing countries. There have been no studies on children and adolescents with cancer from every region of Brazil or on the impact of nutritional status on clinical outcomes. The aim of this study is to assess the association between the nutritional status of children and adolescents with cancer and the prediction of clinical outcomes. METHODS: This was a longitudinal, multicentre, hospital-based study. An anthropometric nutritional assessment was performed, and the Subjective Global Nutritional Assessment (SGNA) was administered within 48 h of admission. Seven hundred and twenty-three patients (aged 2-18 years) were included in the sample, undergoing cancer treatment. They were recruited in 13 reference centres in the five macro-regions of Brazil between March 2018 and August 2019. The outcomes evaluated were readmission within 30 days and death within 60 days of admission. To identify predictors of 60-day survival, Cox regression and log-rank statistics were used to compare Kaplan-Meier curves between the strata. RESULTS: About 36.2% (n = 262) of the samples were malnourished according to the SGNA. Severe malnutrition by the SGNA (relative risk [RR] = 8.44, 95% confidence interval [CI]: 3.35-21.3, P = 0.001) and living in the North region (RR = 11.9, 95% CI: 3.34-42.7, P = 0.001) were associated with the poorest survival. The North (RR = 5.77, 95% CI: 1.29-25.8, P = 0.021), Northeast (RR = 1.46, 95% CI: 1.01-2.11, P = 0.041), Midwest (RR = 0.43, 95% CI: 0.20-0.095, P = 0.036), age group 10-18 years (RR = 0.65, 95% CI: 0.45- 0.94, P = 0.022) and haematologic malignancy (RR = 1.52, 95% CI: 1.10-2.10, P = 0.011) were predictors of readmission within 30 days. CONCLUSIONS: The prevalence of malnutrition was high and related to death. These results highlight the need to use the SGNA in clinical practice alongside classic anthropometric methods for the diagnosis of malnutrition, and the need to standardise care across all Brazilian regions, which should include nutritional care for children and adolescents with cancer.

Muscle Mass Assessed by Computed Tomography at the Third Lumbar Vertebra Predicts Patient Survival in Chronic Kidney Disease.

OBJECTIVE: Muscle mass is a key element for the evaluation of nutritional disturbances in patients with chronic kidney disease (CKD). Low muscle mass is associated with increased morbidity and mortality. The assessment of muscle mass by computed tomography at the third lumbar vertebra region (CTMM-L3) is an accurate method not subject to errors from fluctuation in the hydration status. Therefore, we aimed at investigating whether CTMM-L3 was able to predict mortality in nondialyzed CKD 3-5 patients. METHODS: This is a prospective observational cohort study. We evaluated 223 nondialyzed CKD patients (60.3 ± 10.6 years; 64% men; 50% diabetics; glomerular filtration rate 20.7 ± 9.6 mLmin1.73 m2). Muscle mass was measured by CTMM-L3 using the Slice-O-Matic software and analyzed according to percentile adjusted by gender. Nutritional parameters, laboratory data, and comorbidities were evaluated, and mortality was followed up for 4 years. RESULTS: During the study period, 63 patients died, and the main cause of death was cardiovascular disease. Patients who died were older, had lower hemoglobin and albumin, as well as lower muscle markers. CTMM-L3 below the 25th percentile was associated with higher mortality according to the Kaplan-Meier curve (P = .017) and in Cox regression analysis (crude hazard ratio, 1.87 [95% confidence interval, 1.11-3.16]), also when adjusting for potential confounders (hazard ratio 1.83 [95% confidence interval 1.02-3.30]). CONCLUSION: Low muscle mass measured by computed tomography at the third lumbar vertebra region is an independent predictor of increased mortality in nondialyzed CKD patients.

High prevalence of malnutrition and nutrition impact symptoms in older patients with cancer: Results of a Brazilian multicenter study.

BACKGROUND: Malnutrition in cancer is an independent factor associated with negative clinical outcomes. The objective of this study was to evaluate the prevalence of malnutrition across different age groups in patients with cancer in Brazil and to identify associations with nutrition impact symptoms (NIS). METHODS: In this observational, cross-sectional, multicenter study, the authors evaluated 4783 patients with cancer aged ≥20 years who were admitted to 45 public hospitals in Brazil. Nutritional status, nutritional risk, and NIS were evaluated using the Patient-Generated Subjective Global Assessment. RESULTS: More than one-fourth (25.5%) of all participants were aged ≥65 years. In patients aged ≥65 years, the prevalence of moderate/suspected and severe malnutrition was 55%, it was 45.4% in those aged 51 to 64 years, and it was 36.1% in those aged ≤50 years. Among the NIS with a higher risk of occurrence in patients aged ≥65 years were no appetite (odds ratio [OR], 1.90; 95% CI, 1.62-2.22; P < .05) and dry mouth (OR, 1.40; 95% CI, 1.1-1.67; P < .05). In patients between ages 51 and 64 years, compared with those aged ≤50 years, the NIS with a higher risk of occurrence were no appetite (OR, 1.45; 95% CI, 1.23-1.69; P < .05), dry mouth (OR, 1.22; 95% CI, 1.02-1.45; P < .05), and problems with swallowing (OR, 1.56; 95% CI, 1.25-1.96; P < .05). CONCLUSIONS: The prevalence of malnutrition and the occurrence of NIS are high in hospitalized Brazilian patients aged ≥65 years who have cancer. The occurrence of NIS was higher in the population aged >50 years than in those aged ≤50 years. Nutritional screening and assessment should be performed immediately after hospitalization to enable early diagnosis and multidisciplinary or interdisciplinary intervention(s).

Factors Associated with Sarcopenia in Patients with Colorectal Cancer.

Introduction; Sarcopenia are frequently observed in cancer patients and was associated with poor prognosis. Objectives; to determine the association of nutritional status, body composition, and clinic parameters with sarcopenia in patients with colorectal cancer (CRC). Methods; We conducted a cross-sectional study of 197 patients with CRC. The sarcopenia elements, including lumbar skeletal muscle index (SMI), handgrip strength, and gait speed were measured. The SMI was assessed by computed tomography at third lumbar vertebra. Phase angle (PA), serum albumin (SAlb), muscle attenuation (MA), and the scored patient-generated subjective global assessment (PG-SGA) were also evaluated. Univariate and multivariate analysis of factors associated with sarcopenia were performed. Results; Sarcopenia was present in 29 of 195 patients (15%) and was significantly correlated with advance age, lower body mass index (BMI), SAlb, PA, MA, higher PG-SGA score, and malnutrition (PG-SGA B). In univariate analysis, age, BMI, SAlb, PA, MA, PG-SGA score, and malnutrition (PG-SGA B) were associated with sarcopenia. Multivariable analysis revealed that BMI, SAlb, PA, MA, and PG-SGA score were independent predictors of sarcopenia. Conclusion; BMI, SAlb, PA, MA, and PG-SGA score were independent predictors of sarcopenia in patients with CRC.

Clinical usefulness of the patient-generated subjective global assessment short form© for nutritional screening in patients with head and neck cancer: a multicentric study.

Nutritional screening and assessment are considered essential steps in nutritional care for cancer patients, malnutrition remains underreported in clinical practice. The aim of this study was to analyse the clinical usefulness of the Patient-Generated Subjective Global Assessment short form (PG-SGA SF©) for nutritional screening in patients with head and neck cancer (HNC). This is a multicentre, cross-sectional study involving patients with HNC. The final score of the PG-SGA SF© was obtained and the nutritional status was diagnosed using the Patient-Generated Subjective Global Assessment (PG-SGA)®, classifying them as well-nourished or malnourished. Receiver operating characteristic curve, ordinal logistic regression, and C-statistic were used. In total, 353 patients with HNC were enrolled and the prevalence of malnutrition, according to the PG-SGA®, was 64.02% and the median final score of PG-SGA SF© was 11 points. The final score of the PG-SGA SF© had high accuracy (area under the curve = 0.915), and scores ≥9 had the best performance in diagnosing malnutrition. PG-SGA SF© final score ≥9 was associated with malnutrition (odds ratio = 28.32, 95% confidence interval= 15.98-50.17), with excellent discriminatory power (C-statistic = 0.872). In conclusion, the PG-SGA SF© demonstrated excellent performance for nutritional screening in patients with HNC. Given that it is a simple instrument that is faster to administer than the PG-SGA®, we recommend its use in clinical practice among such patients.

Inflammation, but not skeletal muscle index, is associated with coronavirus disease 2019 mortality in patients with cancer.

BACKGROUND & AIMS: Patients with cancer and coronavirus disease 2019 (COVID-19) have characteristics that can cause the most severe forms of the disease and higher mortality. We aimed to assess the association between computed tomography (CT)-derived muscle abnormalities, anthropometric parameters, inflammation, and mortality in patients with cancer and COVID-19. METHODS: This retrospective study included patients with cancer and COVID-19 admitted between March 1st and December 31st, 2020. All information was collected from medical records (clinical and nutritional parameters, serum albumin, and C-reactive protein [CRP]). Weight loss and body mass index (BMI) were assessed using Global Leadership Initiative on Malnutrition phenotypic criteria. Skeletal muscle index (SMI) and skeletal muscle radiodensity (SMD) at the fourth thoracic vertebra level were assessed using computed tomography scans. RESULTS: This study included 80 patients (61% men, mean age: 58 ± 17 years). Of the patients analyzed, 49% had weight loss >5%, and 14% had low BMI. The median length of hospital stay was 7 (interquartile range: 4-14 days), 27% needed mechanical ventilation, 34% died as a direct consequence of COVID-19 infection and 15% to complications associated with cancer condition. In multivariate logistic regression analysis, low SMI was associated with increased in-hospital mortality [odds ratio (OR): 4.81; 95% confidence interval (95% CI): 1.63; 14.2; p = 0.005), while CRP was associated with COVID-19-related mortality (OR: 1.08; 95% CI: 1.01; 1.15, p = 0.018). CONCLUSION: SMI independently predicts in-hospital mortality in patients with cancer and COVID-19. Additionally, an independent association was observed between CRP and mortality specifically related to COVID-19.

Predictive validity of GLIM malnutrition diagnosis in patients with colorectal cancer.

BACKGROUND: Considering that the validation of the Global Leadership Initiative on Malnutrition (GLIM) remains unclear in patients with colorectal cancer, the present study aimed to assess the agreement, accuracy, sensitivity, specificity, and prognostic effect of the GLIM on survival when compared with the Patient-Generated Subjective Global Assessment (PG-SGA). METHODS: Patients with colorectal cancer who were scheduled to undergo a routine abdominal computed tomography (CT) scan were recruited. Using the GLIM two-step approach, the patients were first screened for malnutrition by using the PG-SGA Short Form (score ≥3). The malnutrition diagnosis was based on the etiologic (disease burden [cancer] or reduced food intake) and phenotypic GLIM criteria, including weight loss, body mass index, and skeletal muscle index at the third lumbar vertebra when using the CT scans. The food intake was assessed by the PG-SGA. RESULTS: This study included 191 patients (age, 60.5 ± 11.3 years; 57% men), and 23% and 32% were malnourished according to the GLIM and the PG-SGA, respectively. The GLIM revealed fair sensitivity (64%), good agreement (kappa = 0.65), specificity (96%), and diagnostic accuracy for detecting malnutrition (area under the receiver operating characteristic curve = 0.80; 95% CI, 0.72-0.88) when compared with the PG-SGA. The malnutrition value according to the GLIM and the PG-SGA was associated with short-term survival. However, only the PG-SGA was associated with long-term survival. CONCLUSIONS: Although showing fair sensitivity, the GLIM had good agreement, specificity, and diagnostic accuracy for malnutrition detection and was an independent predictor of short-term survival in patients with colorectal cancer.

Performance of subjective global nutritional assessment in predicting clinical outcomes: Data from the Brazilian survey of pediatric oncology nutrition.

BACKGROUND: Methods for assessing nutritional status in children and adolescents with cancer is a difficult in clinical practice. The study aimed to evaluate the performance of Subjective Global Nutritional Assessment (SGNA) in predicting clinical outcomes in children and adolescents with cancer in Brazil. METHODS: This was a prospective cohort multicenter study. It was included 723 children and adolescents with cancer aged 2-18 years between March 2018 and August 2019. Nutritional assessment was performed according to World Health Organization recommendations and using SGNA within 48h of hospitalization. Unplanned readmission, length of hospital stay, and post-discharge death were analyzed. Cohen's kappa coefficient was used to ascertain the agreement between body mass index for age (BMI/A) and SGNA. The sensitivity, specificity, positive and negative predictive values, and accuracy of SGNA were estimated. Odds ratios (ORs) with 95% confidence intervals (CIs) were evaluated using multiple logistic regression. RESULTS: The mean patient age was 9.4 ± 4.9 years. SGNA showed that 29.7% (n = 215) and 6.5% (n = 47) patients had moderate and severe malnutrition, respectively. Considering the concurrent validity criterion, SGNA had an OR (95% CI) of 6.8 (3.1-14.9) for predicting low and very low weight for age at admission, with a sensitivity and specificity of 72.4% (59%-82.1%) and 72% (64.2%-78.9%), respectively. SGNA could predict death in children with severe/moderate malnutrition, with an accuracy of 63.8% (63%-65.1%). Logistic multivariate analysis showed that the adjusted effect of death; hematological tumor; living in the northeast, southeast, and midwest regions of Brazil; and older age was associated with malnutrition according to SGNA. CONCLUSION: Based on concurrent validity between SGNA and anthropometry, SGNA performed well and had a good ability to predict death in Brazilian children with cancer.

Phase angle as a marker for muscle abnormalities and function in patients with colorectal cancer.

BACKGROUND AND AIMS: Considering the applicability of phase angle (PhA) as a marker of muscle mass and function, we aimed to investigate whether PhA is a predictor of muscle abnormalities and function in patients with cancer. METHODS: In a sample of patients with colorectal cancer (CRC), PhA was obtained from measurements of resistance and reactance from bioelectrical impedance analysis. Computerized tomography imaging at the third lumbar vertebra was used to evaluate muscle abnormalities by quantifying skeletal muscle index (SMI) and skeletal muscle radiodensity (SMD). Muscle function was assessed by handgrip strength (HGS) and gait speed (GS). RESULTS: This cross-sectional study included 190 participants (X±SD), mean age 60.5 ± 11.3 years; 57% men; 78% had cancer stages III to IV. PhA was highly correlated with SMI (r = 0.70) and moderately correlated with HGS (r = 0.54). PhA explained 48% of the SMI variability (R2 = 0.485), 21% of the SMD variability (R2 = 0.214), 26% of HGS (R2 = 0.261) and 9.8% of GS (R2 = 0.098). In the multivariate model adjusted for age, sex, body mass index, performance status, comorbidities and cancer stage, 1-degree decrease in PhA was associated with low SMI (Odds Ratio (OR) = 6.56, 95% CI: 2.90-14.86) and with low SMI and HGS combined (OR = 11.10, 95% CI: 2.61-47.25). In addition, Receiving Operating Characteristics curve analysis showed that PhA had a good diagnostic accuracy for detecting low SMI, low SMI and SMD combined, low SMD and HGS and low SMI and HGS combined (AUC = 0.81, 95% CI: 0.74-0.88; AUC = 0.88, 95% CI: 0.81-0.95; AUC = 0.80, 95% CI: 0.70-0.91; AUC = 0.82, 95% CI: 0.74-0.89; respectively). CONCLUSIONS: PhA was a predictor of muscle abnormalities and function and had a good diagnostic accuracy for detecting low muscle mass, low muscle mass and radiodensity, low muscle radiodensity and strength, and low muscle mass and strength in patients with CRC.

Postoperative complication rate and survival of patients with gastric cancer undergoing immunonutrition: A retrospective study.

OBJECTIVES: This study aimed to evaluate the effect of preoperative immunonutrition on the rate of postoperative complication and survival of patients with gastric cancer. METHODS: A retrospective cohort was formed after data collection of patients hospitalized with gastric cancer. Postoperative complications classified according to the Clavien-Dindo classification system, length of hospital stay, readmissions, and rates of survival at 6 mo, 1 y, and 5 y were analyzed. A χ2 or Fisher's exact test, Student or Mann-Whitney t test, and Kaplan-Meier and Cox regressions were used in the statistical analysis. RESULTS: A total of 164 patients were included in the study, with 56 patients assigned to the immunonutrition group and 108 to the conventional group. There were no significant differences in postoperative complications between the immunonutrition and conventional groups (51.8% versus 58.3%; P = 0.423). The most frequent complications were fistula and surgical wound infection. Length of hospital stay did not differ between the groups (median of 7.0 d: P = 0.615) and the presence of readmissions did not differ either (12.5% versus 15.7%; P = 0.648). In the multivariate Cox regression, in a pooled model for group, age, sex, body mass index, Charlson comorbidity index, staging, neoadjuvant chemotherapy, and type of surgery, there was a significant difference in survival rates at 6 mo (P = 0.011), 1 y (P = 0.006), and 5 y (P < 0.001). CONCLUSIONS: Preoperative immunonutrition in patients with gastric cancer did not reduce postoperative complications or length of hospital stay. More studies are needed to confirm the benefit of immunonutriton supplementation for overall survival when associated with other protective factors.

Frailty is associated with myosteatosis in obese patients with colorectal cancer.

BACKGROUND & AIMS: We aimed to explore the determinants of muscle fat infiltration and to investigate whether myosteatosis, assessed as muscle fat infiltration percentage (%MFI) and muscle attenuation from computed tomography (CT), is associated with frailty in a group of patients with colorectal cancer (CRC). METHODS: Cross sectional study including CRC patients. CT scan of the third lumbar vertebra was used to quantify body composition and the degree of %MFI (reported as percentage of fat within muscle area). Frailty was defined by Fried et al. (2001) as the presence of more than 3 criteria: unintentional weight loss, self-reported exhaustion, weakness (low handgrip strength), slow walking speed (gait speed) and low physical activity. Obesity was defined according to sex-and-age-specific body fat percentage (%BF) cutoff. RESULTS: A sample of 184 patients (age 60 ± 11 years; 58% men; 29% of patients with frailty) was studied. The sample was divided according to tertiles of MFI% (1st tertile 0 to 2.89%, n = 60; 2nd tertile ≥ 3.9-8.19%, n = 64; 3rd tertile ≥ 8.2-26%, n = 60). Age, females, body mass index, %BF, subcutaneous and visceral adipose tissue and the proportion of patients with frailty were significantly higher in the 3rd %MFI tertile. Phase angle and muscle attenuation were significantly lower in the 3rd %MFI tertile. The determinants of %MFI (r2 = 0.49), which was log transformed due to its normal distribution, were %BF (ß = 0.54; eß = 1.72; 95% CI: 0.032 to 0.051; P < 0.01), age (ß = 0.34; eß = 1.40; 95% CI: 0.016 to 0.032; P < 0.01) and gait speed (ß = -0.12; eß = 0.87; 95% CI: -0.84 to -0.001; P = 0.049). In addition, in obese patients (n = 74) presenting 4 or 5 frailty criteria increased the chance of having higher %MFI and lower muscle attenuation, after adjustment for sex, age and comorbidities when compared to none or 1 criteria. CONCLUSIONS: In a sample of CRC patients, %BF and gait speed were the determinants of %MFI. In addition, markers of myostetatosis were associated with frailty in the obese patients.

Comparative Analysis Between Computed Tomography and Surrogate Methods to Detect Low Muscle Mass Among Colorectal Cancer Patients.

BACKGROUND: We aimed to evaluate the agreement between computed tomography (CT) and surrogate methods applied in clinical practice for the assessment of low muscle mass. In addition, we assessed the association between different muscle-assessment methods and nutrition status, as well as the prognostic value of low muscle mass on survival in patients with colorectal cancer (CRC). METHODS: This is a cohort including 188 CRC patients with 17 months' follow-up (interquartile range: 12-23 months) for mortality. Low muscle mass was evaluated by corrected mid-upper arm muscle area (AMAc) and calf circumference, skeletal muscle mass by bioelectrical impedance analysis (BIA), muscle deficit by physical examination with the Patient-Generated Subjective Global Assessment (PG-SGA), and lumbar muscle cross-sectional area by CT (reference method). RESULTS: The prevalence of low muscle mass ranged from 9.6% to 54.3% according to the method used. The physical examination had the highest κ coefficient compared with CT. Low muscularity was associated with the presence of malnutrition, lower body fat, and low phase angle. The Cox regression models-adjusted for age, sex, and treatment 3 months before study inclusion-showed that severe muscle loss measured by BIA and CT and low muscle mass measured by PG-SGA predicted higher mortality rates. CONCLUSIONS: Compared with CT, the physical examination had the best agreement to assess low muscle mass. Low muscle mass assessed by PG-SGA, BIA, and CT showed similar prognostic values for survival.

Muscle mass assessment by computed tomography in chronic kidney disease patients: agreement with surrogate methods.

BACKGROUND/OBJECTIVES: Patients with chronic kidney disease (CKD) are subjected to muscle wasting. Therefore, it is important to investigate surrogate methods that enable the assessment of muscle mass loss in the clinical setting. We aimed to analyze the agreement between computed tomography (CT) and surrogate methods for the assessment of muscle mass in non-dialysis CKD patients. SUBJECTS/METHODS: Cross-sectional study including 233 non-dialysis patients on CKD stages 3 to 5 (61 ± 11 years; 64% men; glomerular filtration rate 22 (14-33) mL/min/1.73 m2). The muscle mass was evaluated by CT and bioelectrical impedance, skinfold thicknesses, midarm muscle circumference (MAMC), the predictive equations of Janssen and Baumgartner and the physical examination of muscle atrophy from the subjective global assessment. RESULTS: In males, the MAMC showed the best agreement with CT as indicated by the kappa test (k = 0.57, P < 0.01), sensitivity (S = 68%), specificity (S = 89%) and accuracy (area under the curve-AUC = 0.78), followed by the Baumgartner equation (kappa = 0.46, P < 0.01; sensitivity = 60%; specificity = 87% and AUC = 0.73). In female, the Baumgartner equation showed the best agreement with CT (kappa = 0.43, P < 0.01; sensitivity = 57%; specificity = 86% and AUC = 0.71). CONCLUSIONS: The MAMC and Baumgartner equation showed the best agreement with CT for the assessment of muscle mass in non-dialysis CKD patients.

Patient-generated subjective global assessment predicts cachexia and death in patients with head, neck and abdominal cancer: A retrospective longitudinal study.

BACKGROUND & AIMS: Cancer is a complex disease, with poor prognosis when associated with malnutrition. This condition can lead to Cancer Cachexia (CC), a syndrome characterized by loss of muscle mass with or without fat loss, often associated with higher risk of death. Although there are recommended screening tools to assess nutritional status in cancer patients, such as Patient-Generated Subjective Global Assessment (PG-SGA), little is known about CC prediction. The aim was to investigate the association between nutritional status of patients with head, neck and abdominal cancer, assessed by PG-SGA at the day of hospitalization, with CC, hospitalization time and death. METHODS: This is a retrospective longitudinal study, where we collected data of 97 patients about PG-SGA nutritional classification, anthropometry, gender, age, cachexia diagnosis and death. RESULTS: PG-SGA classification was strongly associated with all the anthropometric measures (p < 0.0001). According to PG-SGA classification, 30.61% (n = 15) of patients in group A developed pre-cachexia; 38.24% in group B developed CC (n = 13); and 60% (n = 9) in group C developed refractory cachexia (p < 0.0001). Death rate was 24.49% (n = 12), 54.55% (n = 18) and 80% (n = 12) in groups A, B and C, respectively (p < 0.0001). PG-SGA had good sensibility (89.5%) and accuracy (72%) for CC, and also good specificity (75.51%) and accuracy (69%) for death. CONCLUSIONS: PG-SGA demonstrated a significative association with the variables measured and was able to predict CC and death. This, in addition to its simple applicability, suggests that PG-SGA can be a useful tool to screen cancer patients for CC establishment and death risk.

Effects of ω-3 supplementation on the nutritional status, immune, and inflammatory profiles of gastric cancer patients: A randomized controlled trial.

OBJECTIVE: The aim of this study was to study the effect of ω-3 supplementation on the nutritional status and the immune and inflammatory profiles of patients with gastric cancer during antineoplastic pretreatment. METHODS: This was a randomized, open, controlled longitudinal study with intervention in outpatient patients with gastric cancer. Sixty-eight patients were randomized into two groups and received either a formula enriched with ω-3 (intervention group [IG]) or standard formula without ω-3 (control group) for 30 d consecutively. Nutritional status (based on patient-generated subjective global assessment, bioimpedance, and anthropometric measurements) and immune and inflammatory parameters were collected before and after supplementation. Results were expressed as frequency, median, and interquartile intervals and were compared by non-parametric test. P < 0.05 was considered statistically significant. RESULTS: Thirty-four patients were included in each group. Of the patients, 64.7% were men, 44.1% were older than 60 years, and 45.6% had stage III disease. There was an increase in C-reactive protein in the control group before and after supplementation, in addition to the worsening in some anthropometric parameters, such as arm muscle area and arm muscle circumference. There was maintenance of the immune profile in both groups. An increase in weight gain was observed in the IG but not in the control group (1.2 [0.9-9] versus 0.7 kg [0.4-1.3]; P = 0.03), as was a reduction of interleukin-6 (5.7 [4.1-6.4] versus 6.3 pg/mL [5.6-8.6]; P = 0.03) and a maintenance of nutritional status, after supplementation. CONCLUSIONS: Supplementation with ω-3 leads to weight gain, reduction in the inflammatory profile, and maintenance of the nutritional and immune profiles of these patients, but further studies are needed to examine changes in body composition.

Hospital and homecare malnutrition and nutritional therapy in Brazil. Strategies for alleviating it: a position paper.

INTRODUCTION: Malnutrition in hospitalized patients is not evaluated frequently. However, it is a critical issue given that it has been related to a high rate of infectious complications and increased mortality rates. There is a high prevalence of patients with nutritional impairment in the home environment, which favors their clinical worsening, the increase of re-hospitalizations and, consequently, the increase in public health expenditures. OBJECTIVE: Nutrition experts have thoroughly discussed and written this positioning paper on hospital and homecare malnutrition to describe the prevalence of malnutrition in Brazil. Best practice recommendations for nutrition therapy of patients in hospital and homecare, in particular the use of oral nutritional supplements (ONS), to those who are at risk of malnutrition or malnourished were evaluated, and the impact on clinical and economic data were assessed. In addition, they emphasize that investments in oral nutritional supplementation are also important in the homecare environment (home or nursing homes). MATERIALS AND METHODS: Selected scientific articles on disease-related malnutrition, especially those carried out in Brazil, were assessed. Data on prevalence, clinical outcomes, and economic burdens were reviewed. RESULTS AND CONCLUSION: Several studies have shown the importance of in-hospital nutritional assessment for early detection of malnutrition and early intervention with nutrition therapy, in particular with oral nutritional therapy. Unfortunately, hospital malnutrition remains high in Brazil, with severe consequences for patients. The implementation of universal nutritional screening and diagnosis as well as the therapeutic approach of malnutrition, particularly with the use, when possible, of oral nutrition supplements as the first step to address this condition is still low, and demands the investment in educational resources to change practices. Routine use of nutritional therapy in hospital and homecare settings improves clinical outcomes, is cost effective, and would be expected to help reduce healthcare costs.

Nutrition and Immune-Modulatory Intervention in Surgical Patients With Gastric Cancer.

This study evaluated the effect of an immune-modulatory diet on patients with gastric cancer and identified the parameters associated with postoperative outcomes. This was a single-arm prospective intervention study. At baseline, patients were assessed for nutrition (Patient-Generated Subjective Global Assessment), inflammatory markers (albumin, C-reactive protein, and interleukin 6 [IL-6]), and immune markers (percentage NK, CD4, CD8, and CD4:CD8 ratio); they also received nutrition counseling and high-calorie/protein supplement. A week before surgery, they were assessed for nutrition and inflammatory/immune markers and started on an immune-modulatory supplement until the day before surgery, when they were evaluated again. On the second postoperative day, patients were assessed for inflammatory/immune parameters, and a final nutrition evaluation was performed until the day of discharge. Complications were recorded daily and up to 30 days after discharge. Thirty-seven patients (60 ± 10 years old) were included, and 57% were classified as malnourished. Maintenance of nutrition and immune parameters occurred throughout the study period, but we found a preoperative increase in C-reactive protein (0.1-1.5 mg/dL) and IL-6 (2.0-14.2 pg/mL) and a postoperative increase in the CD4:CD8 ratio (2.3 ± 1.0). Complications and death were seen in 35%, especially patients with higher preoperative IL-6 (2.2-46 pg/mL), lower CD4:CD8 ratio (1.7 ± 0.5), and lower protein (1.2 ± 0.5 g/kg/d) and calorie intake (1552 ± 584 kcal/kg/d). The high-calorie/protein supplementation with the immune-modulating diet was able to maintain the nutrition and immune status of patients with gastric cancer.

Undernutrition as independent predictor of early mortality in elderly cancer patients.

OBJECTIVES: The aim of this study was to evaluate the 1-y survival of elderly patients with cancer and the association between undernutrition and mortality. METHODS: This was a cohort study with elderly patients ages ≥65 y admitted between September and October 2014. A nutritionist performed a Mini Nutritional Assessment-Short Form (MNA-SF) assessment during 48 h of hospital admission and collected data about potential confounding variables (comorbidities, stage of cancer, treatment in the previous 3 mo, and reason for hospitalization). Vital status was determined from the medical records or public records office. Overall survival was estimated using the Kaplan-Meier method. Cox regression was performed to estimate unadjusted hazard ratios. Variables with P < 0.20 by univariate analysis were selected for multivariate analysis. P < 0.05 was considered statistically significant. RESULTS: Of the 136 patients (mean age, 73.1 y; 52.2% men), 29.4%, 41.2%, and 29.4% were classified as normal, at risk for undernutrition, and undernutrition, respectively, according to the MNA-SF. The mortality rate was 31.6% after 12 mo. One-year mortality was higher among the undernourished patients, followed by patients at risk for undernutrition. After adjustment for confounding variables, the multivariate regression Cox model showed that being undernourished according to the MNA-SF increased the risk for death at 1 y (hazard ratio, 5.59; 95% confidence interval, 1.8-17.3; P < 0.001). CONCLUSION: The results showed that the MNA-SF can be a useful tool in identifying elderly patients at higher risk for 1-y mortality.

Dados do Inquérito Brasileiro de Nutrição Oncológica em Pediatria: Estudo Multicêntrico e de Base Hospitalar / Data from the Brazilian Survey of Pediatric Oncology Nutrition: Multicenter, Hospital-Based Study / Datos de Encuesta Brasileña de Nutrición en Oncología Pediátrica: Estudio Multicéntrico Hospitalario

Introdução: A desnutrição é observada em crianças com câncer e está associada a desfechos clínicos negativos. Objetivo: Descrever a prevalência de inadequação do estado nutricional de crianças e adolescentes com neoplasia maligna na admissão hospitalar em Centros de Referência do câncer infantil no Brasil. Método: Estudo transversal aninhado a um estudo de coorte, multicêntrico, de base hospitalar. A amostra probabilística foi feita em dois estágios em cada estrato por Macrorregião pelo método de probabilidade proporcional ao tamanho com um ano de coleta em cada instituição. Foram coletados em 13 instituições de referência dados clínicos, antropométricos, de composição corporal e sobre o questionário de Avaliação Nutricional Subjetiva Global Pediátrica (ANSGP), em até 48 horas da admissão hospitalar, entre março de 2018 e agosto de 2019. Resultados: O estudo totalizou 723 pacientes nas cinco regiões do Brasil. A prevalência de desnutrição moderada e grave foi de 25,9% na faixa etária de 2 a 5 anos, 40,1% de 5 a 10 anos e 39,7% de 10 a 19 anos, de acordo com ANSGP. Segundo o Índice de Massa Corporal/Idade (IMC/I), magreza e magreza acentuada totalizaram 13%, risco de sobrepeso, sobrepeso e obesidade apresentaram uma prevalência de 26,7% de 2 a 5 anos; 24,9% de 5 a 10 anos; e 25,7% de 10 a 19 anos. Conclusão: Evidenciou-se alta prevalência de inadequação nutricional pela ANSGP, sugerindo que a desnutrição pode ser subdiagnosticada quando utilizado somente o IMC/I, fortalecendo a necessidade de utilização de métodos complementares na avaliação nutricional de crianças com câncer

Introduction: Malnutrition is found in children with cancer and is associated with negative clinical outcomes. Objective: To describe the prevalence of inadequate nutritional status of children and adolescents with malignant neoplasm at hospital admission in childhood cancer reference centers in Brazil. Method: Cross-sectional study nested in a multicenter, hospital-based cohort study. The probabilistic sample was carried out in two stages in each stratum by macro-region using the probability method proportional to the size with one year of collection in each institution. Clinical, anthropometric, body composition data and the Pediatric Subjective Global Nutritional Assessment (SGNA) questionnaire were collected from 13 reference institutions within 48 hours of hospital admission, from March 2018 to August 2019. Results: The study totaled 723 patients in the 5 regions of Brazil. The prevalence of moderate and severe malnutrition was 25.9% in the age group of 2 to 5 years, 40.1% in 5 to 10 years and 39.7% in 10 to 19 years, according to the SGNA. According to the Body Mass/Age Index (BMI/I), thinness and marked thinness totaled 13%, risk of overweight, overweight and obesity showed a prevalence of 26.7% from 2 to 5 years, 24.9% from 5 to 10 years and 25.7% from 10 to 19 years. Conclusion: There was a high prevalence of nutritional inadequacy by the SGNA, suggesting that malnutrition can be underdiagnosed when using only the BMI/I, strengthening the need to use complementary methods in the nutritional assessment of children with cancer
