RESUMO
Imbalanced dietary intake is associated with the development of inflammatory bowel diseases (IBDs) and is often observed during the active phases of Crohn's disease (CD) and ulcerative colitis (UC). Cumulative data also suggest the potential for dietary manipulation in avoiding IBD relapse. However, there is a paucity of dietary data from patients in clinical remission to guide such an approach. Our study aimed to characterize the dietary pattern and adequacy of patients with IBD in clinical remission. Data on dietary intake (three alternate 24 h food records) were collected from 40 patients with IBD (20 CD and 20 UC) and 45 gender-matched healthy controls (HC). Statistical comparisons between patients and controls employed Student's t-test, Mann-Whitney U, chi-squared, and Fisher's exact tests. The adequacy of dietary intake of IBD patients was further studied by assessing the nutrient inadequacy prevalence, estimated using the Dietary Reference Intakes (DRI) framework and the Estimated Average Requirement (EAR) parameter. We observed significant dietary imbalances among patients with IBD compared to the HC group, marked by disparities in both macronutrient and micronutrient intakes. Inadequacies with frequencies >80% were observed for the ingestion of total fiber and 13 micronutrients in IBD patients. Our preliminary findings suggest that imbalanced dietary intake is also characteristic among individuals with IBD during clinical remission, corroborating the need for dietary interventions in this population.

PURPOSE OF REVIEW: Cachexia is a complex, multifactorial syndrome primarily characterized by weight loss, muscle wasting, anorexia, and systemic inflammation. It is prevalent in cancer patients and is associated with a poor prognosis, including lower resistance to intervention toxicity, quality of life, and survival, compared to patients without the syndrome. The gut microbiota and its metabolites have been shown to influence host metabolism and immune response. Our article reviews the current evidence suggesting a role of gut microbiota in the development and progression of cachexia, while discussing the potential mechanisms involved. We also describe promising interventions targeting gut microbiota aiming to improve outcomes related to cachexia. RECENT FINDINGS: Dysbiosis, an imbalance in gut microbiota, has been associated with cancer cachexia through pathways involving muscle wasting, inflammation, and gut barrier dysfunction. Interventions targeting gut microbiota, such as probiotics, prebiotics, synbiotics, and fecal microbiota transplantation, have shown promising results in managing this syndrome in animal models. However, evidence in humans is currently limited. SUMMARY: Mechanisms linking gut microbiota and cancer cachexia need to be further explored, and additional human research is necessary to evaluate the appropriate dosages, safety, and long-term outcomes of prebiotic and probiotic use in microbiota management for cancer cachexia.

BACKGROUND & AIMS: Cancer influences body composition, including a loss of muscle mass (MM), associated with worse outcomes. The study aimed to evaluate the agreement between MM estimated by calf circumference (CC) and computed tomography (CT) image as a reference method. METHODS: A cross-sectional study including patients (>20 years) diagnosed with cancer attending a reference center of oncology. Spearman's correlation was performed to verify the correlation between CC and MM by CT, including skeletal muscle area - SMA and skeletal muscle index - SMI. ROC curves, Kappa coefficient, sensitivity, specificity, positive and negative predictive values were obtained. RESULTS: The study included 219 patients, age 62.9 ± 13.1 years (mean ± standard deviation). Low CC was observed in 43.8% of the patients, and 29.2% had low SMI. CC positively correlated with SMA (rho = 0.333) and SMI (rho = 0.329), and fair agreements (K = 0.268) were observed between CC and SMI, with higher and significant values for males (K = 0.332) and patients below 60 years (K = 0.419). The area under the curve (AUC) for low CC to identifying low SMI was equal to 0.685 (CI 95% 0.606-0.765). Low CC presented fair agreement to identify low SMI in the sample; however, the negative predictive value was almost 80% for all analyses. CONCLUSIONS: Low CC is not a surrogate for low SMI in patients with cancer, but it could be an alternative, non-invasive, easy-to-perform method to pre-screen patients with cancer with adequate SMI.

BACKGROUND: The study aims to evaluate the accuracy of isolated nutrition indicators in diagnosing malnutrition in patients with gastric and colorectal cancer and their association with mortality. METHODS: Prospective cohort study involving patients with cancer (n = 178) attending a reference center of oncology at any point in the disease trajectory or treatment. Nutrition status was evaluated in a unique moment by body mass index (BMI), Patient-Generated Subjective Global Assessment (PG-SGA), handgrip strength (HGS), and calf circumference (CC). Kappa coefficient, accuracy, sensitivity, specificity, positive and negative predictive values, and area under the receiver operating characteristic curve (AUC) were calculated for each nutrition indicator (PG-SGA as the reference method). The Cox proportional hazards model was used to assess hazard ratio (HR) and CI of mortality. RESULTS: From the total patients, 11% were underweight, 48% were malnourished (PG-SGA B or C), 43% had low HGS, and 55% presented low CC. There were 46 deaths (25.8%). BMI, HGS, and CC showed poor and fair agreements (κ < 0.30 for all ) and poor accuracy (AUC < 0.70 for all) in identifying malnutrition by PG-SGA. After the adjustment for confounders (age, treatment performed, site, and stage of cancer), PG-SGA (HR, 2.9; 95% CI, 1.5-5.9) and low CC (HR, 2.4; 95% CI, 1.1-5.2) were independent predictors of mortality. CONCLUSION: The nutrition indicators are not accurate in diagnosing malnutrition, whereas PG-SGA and low CC could predict mortality in gastric and colorectal cancer patients. Thus, CC should be combined with PG-SGA in nutrition assessments.

INTRODUCTION: In the last decade, an increasing number of studies investigated markers of Sedentary Behavior (SB) and Physical Activity (PA) in school-age children since they lead to nutritional status changes in this groupOBJECTIVE: To analyze associations between maternal factors and SB and PA of schoolchildrenMETHODS: This is a cross-sectional study involving 410 mothers of children enrolled between the first and the fifth year in municipal schools of Santa Cruz, RN, Brazil. By applying questionnaires, socioeconomic variables of the family, maternal data, and habits related to SB and PA on weekdays and weekends were investigated. Pearson's chi-square test and Fisher's exact test were used to test associationsRESULTS: It was observed that income below one minimum wage and less maternal education were associated with greater active transportation among children (69.3%, p = 0.012 and 68.4%, p = 0.022, respectively). Children from low-income families (65.4%, p = 0.016) and who had six and seven siblings (8.2%, p = 0.023 and 7.6%, p = 0.037, respectively) presented lower SB at the weekend. Low level of maternal education was associated with reduced PA during the week (70.8%, p = 0.024CONCLUSION: Socioeconomic (i.e., family income and number of siblings) and maternal factors (i.e., level of education) are important indicators for time spent on sedentary behavior and physical activity of schoolchildren
INTRODUÇÃO: Na última década, um número crescente de estudos tem se preocupado em investigar marcadores de Comportamento Sedentário (CS) e Atividade Física (AF) em crianças na idade escolar, por serem reconhecidos como causadores de alterações do estado nutricional nesta faixa etáriaOBJETIVO: Analisar os fatores associados maternos sobre o CS e AF de escolaresMÉTODO: Trata-se de uma pesquisa com delineamento transversal, envolvendo 410 mães de crianças matriculadas entre o primeiro e quinto ano nas escolas municipais de Santa Cruz, RN, Brasil. Por meio da aplicação de questionários, foram investigadas variáveis socioeconômicas da família, dados maternos e hábitos relacionados ao CS e AF dos escolares, nos dias da semana e no final de semana. Para testar associações foi utilizado o teste Qui-quadrado de Pearson e Teste Exato de FisherRESULTADOS: Foi observado que uma renda inferior a um salário mínimo e menor escolaridade materna foram associados com maior deslocamento ativo das crianças (69,3%, p = 0,012 e 68,4% p = 0,022, respectivamente). As crianças de famílias com baixa renda (65,4%, p = 0,016) e que tinham seis e sete irmãos (8,2%, p = 0,023 e 7,6%, p = 0,037, respectivamente) apresentam menor CS no final de semana. Um menor grau de escolaridade materna foi associado com uma menor prática de AF durante a semana (70,8%, p = 0,024CONCLUSÃO: Conclui-se que os fatores socioeconômicos (i.e., renda familiar e número de irmãos) e maternos (i.e., nível de escolaridade) são importantes indicadores para o tempo dispendido em comportamento sedentário e atividade física de escolares

OBJECTIVE: Loss of muscle mass is associated with worse outcomes in patients with cancer. The objective of this study was to evaluate the prognostic value of calf circumference (CC) and skeletal muscle index from computed tomography (CT) to predict mortality in patients with cancer. METHODS: A single-center prospective study was conducted with patients aged ≥20 y attending a reference center of oncology and who had recent abdominal CT images. Data were collected through a semistructured form and patients' records and included sociodemographic data (sex, age and ethnicity), clinical data (primary site and staging of tumor and treatments performed), anthropometric variables (body mass index and CC), and outcome (death). Low CC for men was considered to be ≤ 34 cm and for women ≤ 33 cm. Muscle mass was assessed by CT images at the level of L3. The Cox proportional hazard model adjusted for age, sex, and staging of disease was used. RESULTS: A total of 250 patients were evaluated, 52.8% female, with a median age of 63 y (interquartile ratio: 55-73). Normal body mass index was identified in 44.4%; 29.2% had low skeletal muscle index, and 46.4% had low CC. Death by any cause occurred in 16%, and only low CC was a significant predictor of mortality (hazard ratio = 3.01; confidence interval 1.52-5.98; P = 0.002). CONCLUSIONS: Low CC can predict risk of mortality in this cohort of patients. The findings suggest the use of CC as a simple, easy, cost-effective anthropometric measurement to quickly screen patients at risk of death who could benefit from targeted care to improve their prognosis.

ABSTRACT Objective A large number of studies have used abdominal computed tomography (CT) to quantify body composition, and different software programmes have been used to perform these analyses. Thus, this comparison is important to enable researchers to know the performance of more accessible software. Subjects and methods Fifty-four abdominal CT scans of obese (BMI 30 to 39.9 kg/m2), sedentary adults (24-41 years) patients from a Brazilian single center were selected. Two software programs were compared: Slice-O-Matic (Tomovision, Canada) version 5.0 and OsiriX version 5.8.5. The body composition analysis were segmented using standard Hounsfield unit (HU) (adipose tissue: -190 to +30 and skeletal muscle: -29 to +150) and measured at the mid third lumbar vertebra (L3) level on a slice showing both transversal processes. Bland-Altman limits of agreement analyses were used to assess the level of agreement between Slice-O-Matic and OsiriX. Results A total of fifty-four participants were evaluated, with majority women (69%), mean of age 31.3 (SD 6.5) years and obesity grade I most prevalent (74.1%). The agreement, in Bland-Altman analysis, between Slice-O-Matic and OsiriX analisys for the muscle mass tissue, visceral adipose tissue and subcutaneous adipose tissue were excellent (≥ 0.954) with P-values < 0.001. Conclusion These findings show that Slice-O-Matic and OsiriX softwares agreement in measurements of skeletal muscle and adipose tissue and sarcopenia diagnosis in obese patients, suggesting good applicability in studies with body composition in this population and clinical practice.

Gut microbiota composition is influenced by environmental factors and has been shown to impact body metabolism. OBJECTIVE: To assess the gut microbiota profile before and after Roux-en-Y gastric bypass (RYGB) and the correlation with food intake and postoperative type 2 diabetes remission (T2Dr). DESIGN: Gut microbiota profile from obese diabetic women was evaluated before (n = 25) and 3 (n = 20) and 12 months (n = 14) after RYGB, using MiSeq Illumina-based V4 bacterial 16S rRNA gene profiling. Data on food intake (7-day record) and T2Dr (American Diabetes Association (ADA) criteria) were recorded. RESULTS: Preoperatively, the abundance of five bacteria genera differed between patients with (57%) and without T2Dr (p < 0.050). Preoperative gut bacteria genus signature was able to predict the T2Dr status with 0.94 accuracy ROC curve (receiver operating characteristic curve). Postoperatively (vs. preoperative), the relative abundance of some gut bacteria genera changed, the gut microbial richness increased, and the Firmicutes to Bacteroidetes ratio (rFB) decreased (p < 0.05) regardless of T2Dr. Richness levels was correlated with dietary profile pre and postoperatively, mainly displaying positive and inverse correlations with fiber and lipid intakes, respectively (p < 0.05). CONCLUSIONS: Gut microbiota profile was influenced by RYGB and correlated with diet and T2Dr preoperatively, suggesting the possibility to assess its composition to predict postoperative T2Dr.

BACKGROUND: Worsening nutritional status in older adult cancer patients can lead to sarcopenia, a condition that occurs with low quantity or quality of muscle mass associated with low physical function. However, most of the studies with cancer patients have only analyzed the quantity of muscle mass for diagnostic of sarcopenia, without exploring muscle characteristics and physical function. The purpose of the present study is to explore the associations between muscle mass characteristics and physical function in older adult patients with cancer. METHODS: Gastric older cancer patients were enrolled in a cross-sectional study. Computed tomography images of the abdominal region evaluated skeletal muscle mass using the Slice-O-Matic version 5.0 Software program (Tomovision, Montreal, Canada) to determine the parameters of skeletal muscle index (SMI, muscle quantity) and skeletal muscle radiodensity (SMD). The physical function was evaluated through handgrip strength and gait speed test. Four musculature phenotypes were identified: normal SMI and SMD, only low SMI, only low SMD, and low SMI and SMD. Linear regression analyses adjusted by age and tumor stage verified the associations between SMI, SMD and physical function. A One-Way Covariance Analysis with Bonferroni post hoc test was used to compare the physical function variables among the four different phenotypes. RESULTS: In total, 167 patients were evaluated (58.1% males; mean age 69.17⯱â¯7.97â¯years). The results showed that muscle mass characteristics explains, at least partially, the variability in handgrip strength and gait speed in a direct relationship. The phenotypes with low muscular SMI and/or SMD presented worse performances in handgrip strength and gait speed tests. When stratified for sexes, the significant difference occurs only in males. CONCLUSIONS: Low SMD has negatively impacted physical function in older adults with gastrointestinal cancer, especially in males.

BACKGROUND: Chemotherapy is an effective treatment with good clinical response in patients with cancer. However, it can cause exacerbated toxicities in patients and consequently change the course of treatment. Some factors may interfere with this toxicity such as body composition, especially in gastrointestinal cancer. The aim of this study was to evaluate the effects of body composition, nutritional status, and functional capacity scale in predicting the occurrence of toxicities in gastrointestinal cancer patients during chemotherapy treatment. METHODS: This is a prospective study with gastrointestinal cancer patients at the beginning of chemotherapy treatment. Sarcopenia and muscle attenuation were assessed using the skeletal muscle index from computerized tomography by measuring cross-sectional areas of the L3 tissue (cm2 /m2 ). Cachexia was graded according to involuntary weight loss associated with sarcopenia. Nutritional status was assessed by using anthropometric evaluation and Patient-Generated Subjective Global Assessment. Functional capacity was evaluated by handgrip strength and Eastern Cooperative Oncology Group (ECOG) Performance Status scale. Haematological gastrointestinal and dose-limiting toxicities (DLTs) were defined according to National Cancer Institute Common Toxicity Criteria. The associations among sarcopenia, cachexia, nutritional status, and functional capacity with DLT were assessed by univariate and multivariate Cox regression model. RESULTS: A total of 60 patients were evaluated (55% male, 60.9 ± 14.0 years) and followed up for a mean of 55 days. Most patients had normal weight (44.2%) and good ECOG Performance Status (≤1) at baseline (78%). During the chemotherapy period, the most prevalent toxicities were diarrhoea, nausea, and anorexia, but the presence of DLT was similar between cycles (P > 0.05). Cachexia was associated with a higher toxicity manifested by diarrhoea (P = 0.02), nausea (P = 0.02), and anorexia (P < 0.01 and P = 0.03 at Cycles 1 and 2, respectively). Sarcopenic and cachetic individuals experienced more toxicities and DLT during chemotherapy. The only factors associated with DLT in the multivariate Cox regression analyses including the presence of metastasis and the chemotherapy protocol were cachexia and the ECOG scale (P < 0.001 for both). CONCLUSIONS: Cachexia and ECOG score may identify patients with an increased risk for developing severe toxicity events during chemotherapy treatment for gastrointestinal cancer.

Introdução: O câncer é uma enfermidade caracterizada pelo (El cáncer es una enfermedad que se caracteriza por el) crescimento desordenado de células, cujo tratamento com quimioterapia atua no seu controle ou (cuyo tratamiento con quimioterapia actúa en su control o) remissão e pode prolongar a sobrevida. No entanto (Sin embargo), a quimioterapia pode causar uma série de efeitos colaterais, denominados quimiotoxicidade, levando ao déficit nutricional e comprometendo sua tolerância e (llevando al déficit nutricional y comprometiendo su tolerancia y) eficácia. Objetivo: Verificar a associação da quimiotoxicidade com o estado nutricional de pacientes oncológicos. Métodos: Estudo transversal, de caráter retrospectivo, com análise de prontuário (con análisis de historia clínica) de pacientes com neoplasia de tumores sólidos, com 3 ciclos realizados de quimioterapia. Foram coletadas variáveis (Fueron contempladas variables) sociodemográficas, clínicas, antropométricas e a quimiotoxicidade foi categorizada conforme a National Cancer Institute (NCI). Resultados: Foram avaliados 126 pacientes, com idade média 54.6 ± 13.9 anos, predominantemente do sexo feminino (68.3%). As neoplasias mais prevalentes foram mama (51%) e trato gastrointestinal (34.5%) e o estadiamento IV foi prevalente (con prevalencia del estadio IV) (40.5%). A quimiotoxicidade apresentou-se desde o primeiro ciclo, com 52.5% de toxicidade bioquímica. Comparando o primeiro e terceiro ciclo não foi observada associação significativa entre a toxicidade e o índice de massa corporal (IMC), leucócitos, plaquetas e hemoglobina, mas observou-se tendência na toxicidade (pero se observó una tendencia en la toxicidad) de neutrófilos (p = 0.053). A toxicidade gastrointestinal afetou significativamente a perda de peso durante o (la pérdida de peso durante el) tratamento (p = 0.024). Conclusão: A quimiotoxicidade foi observada desde o primeiro ciclo, no entanto apenas a toxicidade do trato gastrointestinal apresentou (sin embargo, solo la toxicidad del tracto gastrointestinal presentó una) associação com a perda de peso corporal.
Introduction: Cancer is a disease characterized by the uncontrolled growth of cells, whose treatment with chemotherapy acts as a control or remission and may prolong survival. However, chemotherapy can cause a number of side effects, called chemotoxicity, leading to malnutrition and compromising its effectiveness and tolerance. Objective: To investigate the association between chemotoxicity and the nutritional status of cancer patients. Methods: Longitudinal and retrospective study with chart analysis of patients with cancer of solid tumors, with at least 3 cycles of chemotherapy performed. Sociodemographic, clinical, anthropometric variables were collected and chemotoxicity was categorized according to the National Cancer Institute (NCI, 1999). Results: We evaluated 126 patients, mean age of 54.6 ± 13.9 years, predominantly female (68.3%). The most common cancers were breast (51%) and gastrointestinal tract (34.5%) and most were classified as stage IV (40.5%). Chemotoxicity showed up from the first cycle, with 52.5% biochemical toxicity. Comparing the first and the third cycles, no difference in toxicity was observed in relation to body mass index (BMI), white blood cells, platelets and hemoglobin; but there was a trend in the association of toxicity with neutrophils (p = 0.053). The GI toxicity significantly affected weight loss during treatment (p = 0.024). Conclusion: chemotoxicity was observed from the first cycle; however only the toxicity of the gastrointestinal tract was associated with weight loss.

Introduction: The number of new cancer cases has increased over the years, placing this disease among the most prevalent worldwide. Studies show that the quality of life of cancer patients is impaired and that there is an association between malnutrition and reduced quality of life (QoL). Objective: To investigate the association between nutritional status and quality of life of cancer patients undergoing chemotherapy. Methods: Cross-sectional study involving 45 cancer patients from the outpatient chemotherapy service at a university hospital in Northeast Brazil. Anthropometric measurements and QoL were assessed by applying the Quality of Life Questionnaire. Results: There was a high percentage of malnutrition, ranging from 15.6% according to body mass index, to 43.9%, according to the muscular circumference of the arm. Median score was verified at 50.0 (Q1 = 41.7; Q3, 50.0) on the scale of general QoL. There were no significant correlations between nutritional status and QoL scores. Only the cognitive performance scale showed inverse correlation with triceps skinfold (TSF) (p = 0.033) and arm circumference (p = 0.011). Regarding the level of symptoms, diarrhea correlated directly with PCT (p = 0.025). Conclusion: There was impairment of QoL in the aspect of overall health. Although many studies have shown association between malnutrition and low QoL, this relationship was not observed in this investigation
Introdução: Os números de novos casos de câncer vêm aumentando ao longo dos anos (La cantidad de nuevos casos de cáncer está aumentando a lo largo de los años), fazendo com que esta doença esteja entre uma das mais prevalentes no (provocando que esta enfermedad sea una de las más prevalentes en el) mundo. Estudos evidenciam que a qualidade de vida dos pacientes oncológicos está prejudicada e que há associação (está deteriorada y que existe una asociación) entre desnutrição e redução da qualidade de vida (QV). Objetivo: Verificar a associação do estado nutricional com a qualidade de vida de pacientes oncológicos em tratamento quimioterápico. Métodos: Estudo transversal envolvendo 45 pacientes oncológicos captados do serviço ambulatorial de quimioterapia de um hospital universitário localizado no Nordeste brasileiro. Foram avaliadas (Fueron evaluadas) medidas antropométricas e a QV, a partir da aplicação do Quality of life Questionnaire. Resultados: Observou-se elevado percentual de desnutrição, variando de 15.6%, segundo o (según el) índice de massa corporal, a 43.9%, segundo a circunferência muscular do braço (del brazo). Foi verificada uma pontuação mediana de 50.0 (Q1 = 41.7; Q3 = 50.0) para a escala de estado geral de QV. Não foram observadas importantes correlações entre os estado nutricional e os escores (puntajes) de QV. Apenas escala de desempenho cognitivo apresentou correlação inversa com a prega cutânea tricipital (el pliegue cutáneo del tríceps) (PCT) (p = 0.033) e circunferência do braço (p = 0.011). Em relação à escala de sintomas, a diarréia se correlacionou diretamente a PCT (p = 0.025). Conclusão: Verificou-se comprometimento da (compromiso de la) QV no aspecto de saúde global. Embora muitos estudos demonstrem associação entre a desnutrição e baixa (Aunque muchos estudios demuestren la asociación entre desnutrición y baja) QV, essa relação não foi evidenciada nessa (no fue probada en esta) investigação
