RESUMEN
PURPOSE: Surgical patients are routinely subjected to long periods of fasting, a practice that can exacerbate the metabolic response to trauma and impair postoperative recovery. The aim of this study was to evaluate the association between preoperative fasting time and clinical outcomes in surgical patients. METHODS: An observational, prospective study with a non-probabilistic sample that included patients of both sexes, aged over 18, undergoing elective surgeries. Data were extracted from electronic medical records, and a questionnaire was applied in 48 hours after surgery. Variables related to postoperative discomfort were assessed using an 11-point numeric rating scale. RESULTS: The sample consisted of 372 patients, and the duration of the surgical event ranged from 30-680 minutes. The incidence of nausea (26.34%) was twice that of vomiting (13.17%) and showed an association with the surgical procedure's size (p = 0.018). A statistically significant difference was observed only between pain intensity and preoperative fasting times for liquids (p = 0.007) and postoperative fasting time (p = 0.08). The occurrence of postoperative complications showed no association with preoperative fasting time (p = 0.850). CONCLUSIONS: Although no association was observed between preoperative fasting time and surgical complications, it is noteworthy that both recommended and actual fasting time exceeded the proposed on clinical guidelines.

PURPOSE: To evaluate the prognostic value of C-reactive protein (CRP), albumin, CRP/albumin ratio (CAR), and modified Glasgow Prognostic Score (mGPS) at different thresholds in patients with advanced cancer in palliative care. METHODS: Prospective cohort study with patients evaluated at a palliative care unit in Brazil between July 2016 and March 2020. We included patients ≥ 20 years old, both sexes, able to provide the necessary information or accompanied by someone able to do so, and Karnofsky Performance Status ≥ 30 %. The exclusion criteria were the absence of laboratory data and previous diagnosis of autoimmune and infectious diseases. The thresholds analyzed were: CRP < 5 vs. 5-10 vs. > 10 mg/L, albumin < 2.4 vs. 2.4-2.9 vs. 3.0-3.5 vs. > 3.5 g/dL; CAR <1.2 vs. 1.2-2.0 vs. > 2.0, and mGPS equal to 0 vs. 1 vs. 2. Kaplan-Meier curves and Cox regression models (with hazard ratios [HR] and 95% confidence interval [CI]) were used to evaluate prognostic value, and the concordance statistic (C-statistic) was used to evaluate the predictive accuracy of these thresholds to predict death within 90 days. RESULTS: A total of 1,877 patients were included. Median overall survival was 51 (19;124) days and decreased in line with the deterioration of the inflammatory biomarkers. According to the Cox regression models, HR increased as the thresholds worsened (CRP: 1.74 [95% CI, 1.50-2.02] to 2.30 [95% CI, 2.00-2.64]; albumin: 1.77 [95% CI, 1.52-2.07] to 2.60 [95% CI, 2.15-3.14]; CAR: 1.47 [95% CI, 1.21-1.77] to 2.35 [95% CI, 2.05-2.69]; mGPS: 1.78 [95% CI, 1.40-2.23] to 1.89 [95% CI, 1.65-2.15]). All the inflammatory biomarkers evaluated showed discriminatory accuracy for predicting death (C-statistic >0.70), with CAR as the best parameter (C-statistic: 0.80). CONCLUSION: Our results suggest that CRP, albumin, CAR, and mGPS can be used as clinically meaningful biomarkers to stratify patients with advanced cancer in palliative care according to the severity of these indicators.

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.

RESUMEN
OBJECTIVES: The aim of this study was to evaluate the association of the dietary inflammatory index (DII) with the nutritional status and metabolic control of children and adolescents with type 1 diabetes mellitus. METHODS: This was a cross-sectional study that examined data of children and adolescents ages 7 to 16 y diagnosed with type 1 diabetes mellitus. Dietary intake was assessed using a 24-h dietary recall, from which the DII was calculated. The outcomes were body mass index, lipid profiles (low-density lipoprotein cholesterol and non-high-density lipoprotein cholesterol), and glycated hemoglobin. The DII was evaluated in tertiles and in a continuous way. Multiple linear regression was adopted in the analysis, with P < 0.05 considered significant. RESULTS: Overall, 120 children and adolescents with a mean age of 11.7 (± 2.8) y were included, 53.3% (n = 64) of whom were girls. Excess weight was present in 31.7% participants (n = 38). The average DII was +0.25, ranging from -1.11 to +2.67. Higher values of selenium (P = 0.011), zinc (P = 0.001), fiber (P < 0.001), and other micronutrients were observed in the first tertile of the DII (diet with more antiinflammatory potential). The DII appeared as a predictor of body mass index (P = 0.002; ß = 0.23; 95% confidence interval [CI], 0.39-1.75) and non-high-density lipoprotein cholesterol (P = 0.034; ß = 0.19; 95% CI, -13.5 to 0.55). There was a tendency for DII to be associated with glycemic control (P = 0.09; ß = 0.19; 95% CI, -0.04 to 0.51). CONCLUSIONS: The inflammatory potential of the diet was associated with increased body mass index and aspects related to metabolic control in children and adolescents with type 1 diabetes mellitus.

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.

AIM: This study evaluated the association between risk of malnutrition and performance status, and mortality in hospitalized breast cancer patients. METHODS: Prospective cohort study with hospitalized breast cancer patients evaluated at a referral Cancer Center. The Risk of malnutrition was assessed by the Patient-Generated Subjective Global Assessment (PG-SGA) and performance status was determined using the Eastern Cooperative Oncology Group Performance Status Scale (ECOG PS). Logistic regression was used to analyze the factors associated with death, using the odds ratio (OR) with a 95% confidence interval (CI) as an effect measure. RESULTS: A total of 195 woman were included, with a mean age of 56.3 (±12.6) years. Patients with an overall PG-SGA score ≥18 (OR: 2.11; 95% CI: 1.03-4.62) and ECOG PS ≥ 3 (OR: 3.34; 95% CI: 1.48-7.52) had a higher occurrence of death during hospitalization, regardless of age or disease stage. The concomitant presence of these two factors improved the accuracy of the association (OR: 5.32; 95% CI: 3.11-9.76) and showed good predictive accuracy (C-statistics: 0.77). CONCLUSION: Nutritional risk and poor performance status were associated with a higher occurrence of death in women with breast cancer. The use of these two indicators improves their predictive accuracy for mortality.

The aim of this study was to evaluate the association of overweight, obesity, excess central adiposity, hyperglycemia, and diabetes mellitus with tumor characteristics in breast cancer. In this retrospective cohort study that enrolled 2127 women with breast cancer, the independent variables collected were fasting blood glucose, body mass index, central adiposity (waist circumference and waist-to-hip circumference ratio (WHR)), and waist-to-height ratio. The tumor characteristics (infiltrating, ductal grade, hormone receptor-positive (HR+), human epidermal growth factor receptor, triple negative, size, lymph node involvement, and clinical stage) were the dependent variables. Most of the women were postmenopausal (73.5%), with an infiltrating tumor (83.0%), HR+ (82.0%), and overweight or obese (71.0%). For the premenopausal women, obesity was associated with grade 3 ductal tumor (odds ratio (OR): 1.70; 95% confidence interval (95% CI): 1.09-2.66), triple negative (OR: 1.37, 95% CI: 1.08-3.24), and size ≥ 2 cm (OR: 2.20, 95% CI: 1.36-3.56). For the postmenopausal women, obesity was associated with WHR, infiltrating tumor (OR: 1.73, 95% CI: 1.56-1.95), size ≥ 2 cm (OR: 1.38, 95% CI: 1.11-1.71), lymph node involvement (OR: 1.24, 95% CI: 1.02-1.56), and stages III-IV (OR: 1.76, 95% CI: 1.30-2.65). Excess body weight and central adiposity were associated with tumor aggressiveness characteristics in women with breast cancer, confirming the importance of nutritional status.

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.

Malnutrition is an important prognostic indicator of laryngeal squamous cell carcinoma. Retrospective study with head and neck cancer patients who underwent total laryngectomy. 243 patients of both sex were evaluated. The univariate analyses demonstrated an increased risk of death for the patients with greater weight loss, hypoalbuminemia, radiotherapy as an initial treatment, salvage surgery, and radical neck dissection. In a Multivariate Cox regression, older age (p = 0.03, 95% confidence interval [CI] 1.003-1.06, hazard ratio [HR] 1.029), Nutritional Risk Index ≤100 (p = 0.008, 95% CI 1.18-3.12, HR 1.921) and adjuvant radiotherapy (p = 0.029, 95% CI 0.31-3.12, HR 0.544) demonstrated prognostic significance in survival. Nutritional status is a modifiable variable and these findings highlight the need to adoption of simple nutritional assessment methods routinely during the treatment of head and neck cancer patients, in order to help improve prognosis after surgery.

We aimed to evaluate the relationship between food intake of lipids with nonalcoholic fatty liver disease (NAFLD) and/or liver fibrosis in people living with HIV/AIDS (PLWHA). In this cross-sectional study, transient elastography was used to detect the presence of NAFLD and/or liver fibrosis. The dietary intake of fats and fatty acids (FA) were assessed by two 24 h dietary recalls (24-HDR) (n = 451). Multivariate logistic regression models were performed. Participants with higher intake of total fat were associated with higher odds for NAFLD compared to those with lower consumption [adjusted odds ratio (aOR) = 1.91 (95% confidence interval (95% CI) 1.06-3.44)]. Furthermore, participants with intermediate intake of n6-PUFA (n6-poly-unsaturated FA) and lauric FA had lower odds for NAFLD, respectively aOR = 0.54 (95% CI 0.3-0.98) and aOR = 0.42 (95% CI 0.22-0.78). Additionally, a higher intake of myristoleic FA (fourth quartile) was a significant protective factor for NAFLD [aOR = 0.56 (95% CI 0.32-0.99)]. Participants with higher intake of lauric FA [0.38 (95% CI 0.18-0.80)], myristic FA [0.38 (0.17-0.89)], palmitoleic FA [0.40 (0.19-0.82)] and oleic FA [0.35 (0.16-0.79)] had positively less odds of having liver fibrosis. On the other hand, higher intake of n-6 PUFA was significantly associated with fibrosis [aOR = 2.45 (95% CI 1.12-5.32)]. Dietary assessment of total fat and FA should be incorporated into HIV care as a tool for preventing NAFLD and fibrosis in PLWHA.

AIMS: The aims were to evaluate the consumption of ultra-processed foods by pregnant women with pre-existing diabetes mellitus (DM) using the carbohydrate counting method, in addition to investigating the association with total gestational weight gain and glycemic control. METHODS: A cohort study of adult Brazilian pregnant women with pre-existing DM. Dietary intake was evaluated adopting the NOVA classification to identify the reported consumption of ultra-processed foods. Weight was measured at all consultations and laboratory tests were evaluated at each gestational trimester. Multivariate linear regression was used in the analysis. RESULTS: Pregnant women (n = 42) presented mean total gestational weight gain of 12.02 ± 4.8 kg, 65.8% of them with inadequate weight gain. Daily consumption of ultra-processed foods was 272.37 ± 170.55 kcal. The increase of every 1 kcal in the calorie intake from ultra-processed foods in the third trimester increased glycated hemoglobin by 0.007% (ß = 0.007, p = 0.025), raised 1-h postprandial glucose by 0.14 mg/dL (ß = 0.143, p = 0.011), and added 0.11 kg to total gestational weight gain (ß = 0.11, p = 0.006). CONCLUSION: Ultra-processed food consumption influenced glycemic control and total gestational weight gain in pregnant women with DM.
RESUMEN
BACKGROUND: Surgery has become the treatment of choice for head and neck cancer (HNC) in most cases. Preoperative fasting abbreviation and nutrition screening have been suggested to reduce the occurrence of postoperative complications. This study aimed to evaluate the addition of whey protein in the preoperative fasting abbreviation and to analyze the association of nutrition status on postoperative complications in patients with HNC. METHODS: A randomized, single-blind clinical trial was performed. Patients recruited from March to November 2018 at a national cancer reference center in Brazil were divided into 2 groups: intervention group (clear fluids with carbohydrate plus whey protein [CHO-P]) and control group (clear fluids with carbohydrate only [CHO]). All patients were evaluated by the Patient-Generated Subjective Global Assessment (PG-SGA) and body mass index. Logistic regression analyses were performed to assess associations between the studied variables, generating odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS: A total of 49 patients met the eligibility criteria and enrolled in the study. A PG-SGA score of 4-8, indicating moderate malnutrition (OR, 10.91; 95% CI, 1.05-112.91), was an independent factor that increased the risk of postoperative complication, whereas the CHO-P group (OR, 0.04; 95% CI, 0.01-0.26) was found to be an independent factor in reducing such risk. CONCLUSION: The addition of whey protein to clear fluids (CHO-P group) was associated with a reduced risk of postoperative complications compared with the CHO group. Furthermore, moderate malnourishment was associated with an increased risk of postoperative complications for patients with HNC.

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

Non-alcoholic fatty liver disease (NAFLD) is a chronic disease affecting up to 25% of the population worldwide. n-3 long-chain polyunsaturated fatty acids (n-3 PUFA) have been associated with improved clinical parameters of NAFLD. Our purpose was to conduct a pilot study to evaluate the effects of n-3 PUFA supplementation in a randomized, double-blind, placebo-controlled clinical study performed on NAFLD individuals diagnosed by ultrasound. Patients received n-3 PUFA (n = 13) or placebo (n = 11) supplementation for six months. Circulating miR-122 expression (determined by quantitative real time-polymerase chain reaction (qRT-PCR), liver fibrosis (FibroScan®), red blood cells (RBC) fatty acids (gas chromatography), and biochemical tests were performed at baseline and after intervention. After the intervention, in the n-3 PUFA group, docosahexaenoic acid (DHA) and omega index increased significantly in RBC (p = 0.022 and p = 0.012, respectively), in addition to a significant reduction in alkaline phosphatase (ALP) (p = 0.002) and liver fibrosis (p = 0.039). However, there was no change in the expression of circulating miR-122 in both groups. Our results showed that omega-3 PUFA were incorporated in erythrocytes after six months of fish oil supplementary intake, and that n-3 PUFA were effective in reducing ALP and liver fibrosis without altering the expression of circulating miR-122 in individuals with NAFLD.

BACKGROUND: Despite clinical trials with antioxidant supplementation, few studies have been conducted to evaluate the nutritional status of antioxidant vitamins and minerals, and none have reported on the status of these serum antioxidants associated with the dietary intake of antioxidants by non-alcoholic fatty liver disease (NAFLD) patients. OBJECTIVE: To evaluate association between serum and dietetics antioxidants with liver fibrosis in patients with NAFLD. METHODS: Across-section analysis with out with 72 patients diagnosed with NAFLD. Hepatic fibrosis was measured by FibroScan®, and liver stiffness ≥7.9 kPa was considered to indicate advanced fibrosis. Retinol, alpha-tocopherol, ascorbic acid, beta-carotene, serum zinc, and selenium were evaluated, as was the dietary intake of these micronutrients in the previous 24 h (using 24-h dietary recall). The Mann-Whitney test was used to compare the fibrosis groups and, a linear regression analysis was performed to determine associated risk factors between age, sex, BMI, hepatic fibrosis, and serum antioxidants. RESULTS: A high proportion of inadequate serum retinol (20.8%), vitamin C (27%), and selenium (73.6%) was observed in the patients with NAFLD, in addition to a significant inadequacy of vitamin A (98.3%) and vitamin E (100%) intake. Patients with advanced liver fibrosis had reduced levels of serum retinol (P = 0.002), with liver fibrosis being the independent risk factor associated with serum retinol lower. CONCLUSION: Hepatic fibrosis was associated with a reduction in serum retinol and was reduced in advanced fibrosis. NAFLD patients showed an important serum deficiency and insufficient dietary intake of the evaluated micronutrients.
RESUMEN
OBJECTIVES: Cancer cachexia (CC) is a multifactorial syndrome that is associated with worse outcomes. Several criteria for its diagnosis have been suggested, but notable disparities exist. This study compared different diagnostic criteria for CC in patients with incurable cancer who are in palliative care. METHODS: A prospective cohort study was conducted at the National Cancer Institute in Brazil. Patients were classified by three CC diagnostic criteria, and comparisons between clinical, nutritional, and functional variables were verified according to the CC stage identified. Kaplan-Meier survival curves and Cox regression were used for the survival analysis. Concordance statistics were used to test the prognostic predictive accuracy of the criteria. RESULTS: The prevalence of cachexia in the 1384 patients included in the study varied from 13.8% to 53.9% according to the classification criteria used. All criteria distinguished noncachectic patients from other categories according to the majority of the domains studied. However, the results were inconsistent in distinguishing patients with intermediate cachexia (mainly precachexia) from noncachectic and cachectic patients. Patients with cachexia or refractory cachexia faced a higher risk of 90-d mortality. The criteria described by Vigano et al. were found to be better at distinguishing the stages of CC regarding overall survival (hazard ratio increases according to CC severity: 1.87 to 2.87; concordance statistic: 0.74). CONCLUSIONS: Our results demonstrate the disparities in existing CC diagnostic criteria and their inability to discriminate intermediate stages. Vigano et al.'s criteria is/was the most effective in predicting the prognosis. The development of new diagnostic criteria to improve CC classification requires future exploration.

AIM: to describe physical activity and ultra-processed foods consumption, their changes and sociodemographic predictors among adolescents from countries in Europe (Italy and Spain) and Latin America (Brazil, Chile, and Colombia) during the SARS-CoV-2-pandemic period. METHODS: Cross-sectional study via web survey. International Physical Activity Questionnaire (IPAQ) and weekly ultra-processed food consumption data were used. To compare the frequencies of physical activity status with sociodemographic variables, a multinomial logistic and a multiple logistic regression for habitual ultra-processed foods was performed. In final models, p < 0.05 was considered significant. RESULTS: Sample of 726 adolescents, mostly females (59.6%) aged 16-19 years old (54.3%). Adolescents from Latin America presented odds ratio (OR) 2.98 (CI 95% 1.80-4.94) of being inactive and those whose mothers had higher level of education were less active during lockdown [OR 0.40 (CI 95% 0.20-0.84)]. The habitual ultra-processed consumption was also high during this period in all countries, and more prevalent in Latin America. CONCLUSION: A higher prevalence of inactivity was observed in this population, but reductions of physical activity and habitual ultra-processed consumption during the pandemic were more pronounced in Latin America. Our findings reinforce the importance of promoting a healthy lifestyle, i.e., exercise and diet, during periods of social isolation.

Confinement due to the COVID-19 pandemic can influence dietary profiles, especially those of adolescents, who are highly susceptible to acquiring bad eating habits. Adolescents' poor dietary habits increase their subsequent risk of degenerative diseases such as obesity, diabetes, cardiovascular pathologies, etc. Our aim was to study nutritional modifications during COVID-19 confinement in adolescents aged 10 to 19 years, compare them with their usual diet and dietary guidelines, and identify variables that may have influenced changes. Data were collected by an anonymous online questionnaire on food intake among 820 adolescents from Spain, Italy, Brazil, Colombia, and Chile. The results show that COVID-19 confinement did influence their dietary habits. In particular, we recorded modified consumption of fried food, sweet food, legumes, vegetables, and fruits. Moreover, gender, family members at home, watching TV during mealtime, country of residence, and maternal education were diversely correlated with adequate nutrition during COVID-19 confinement. Understanding the adolescents' nutrition behavior during COVID-19 lockdown will help public health authorities reshape future policies on their nutritional recommendations, in preparation for future pandemics.

OBJECTIVE: To identify factors associated with referral to an exclusive palliative care unit (PCU) in patients with colorectal cancer (CRC). METHODS: Retrospective cohort study with patients having CRC of both sexes treated at a hospital unit, aged ≥20 years. Data were extracted from the medical records of pretreatment patients between January 2008 and August 2014. The outcome was referral to the PCU within 5 years. Logistic regression analyses were performed to assess whether sociodemographic, clinical, nutritional, and biochemistry data were associated to referral, generating odds ratios (OR), and 95% confidence intervals (CI). RESULTS: Four hundred fifteen patients were evaluated. The Patient-Generated Subjective Global Assessment demonstrated a prevalence of malnutrition of 57.3%. One hundred one (24.3%) patients were referred to the PCU after 16.3 months (interquartile range: 7.2-33.5). These patients were more likely to be at an advanced stage of the disease and have malnutrition and exacerbated systemic inflammation. Tumor stage III and IV (OR: 2.05; 95% CI: 1.12-3.76) and neutrophil-to-lymphocyte ratio (NLR) ≥3 (OR: 1.89; 95% CI: 1.12-3.17) were predictors of an increased chance of referral to the PCU. CONCLUSION: Advanced disease stage and NLR were associated with referral of patients with CCR to a PCU.
