RESUMO
La desnutrición por enfermedad afecta a un número elevado de pacientes hospitalizados que provoca una prolongada estancia hospitalaria por el retraso en la recuperación. Con el objetivo de determinar la relación de la intervención nutricional con los días de estancia hospitalaria en pacientes con malnutrición internados en el Hospital de Clínicas, Facultad de Ciencias Médicas -Universidad Nacional Asunción entre el año 2015 al 2021, se realizó un estudio observacional descriptivo retrospectivo de corte transverso que incluyó 49 registros de pacientes internados de los cuales 30 correspondieron a mujeres y 19 a hombres, el promedio de edad en mujeres fue de 53.7±18.9 años y para hombres de 50.7±17.9 años. Los resultados muestran la presencia de desnutrición calórico proteica en el 53.1% de los pacientes a través de la Nutritional Risk Screenig 2002, el 26.5% mostró desnutrición calórica proteica por Valoración Global Subjetiva, se observó sobrepeso en el 8.2% de los pacientes, así como obesidad y normopeso en el 6.1%. Tras asociar la intervención nutricional que recibieron los pacientes internados se pudo evidenciar asociación en aquellos que permanecieron menos días internados, por otra parte, no se encontró relación entre la edad, el peso y el índice de masa corporal con la estancia hospitalaria. Se pudo demostrar que la intervención nutricional a través del soporte nutricional puede favorecer a la mejoría del paciente y a una menor estancia hospitalaria, sin embargo, no puede ser ampliamente confirmada por el número reducido de registros al cual se pudo acceder.
Disease malnutrition affects a high number of hospitalized patients that causes a prolonged hospital stay due to recovery delay. With the objective of determining the relationship of nutritional intervention with the days of hospital stay in patients with malnutrition admitted to the Hospital de Clinics, Faculty of Medical Sciences - National University Asunción between 2015 and 2021, a retrospective descriptive observational study was conducted Transverse cutting that included 49 records of interned patients of which 30 corresponded to women and 19 to men, the average age in women was 53.7 ± 18.9 years and for men of 50.7 ± 17.9 years. The results show the presence of protein calorical malnutrition in 53.1% of patients through the Nutritional Risk Screenig 2002, 26.5% showed protein caloric malnutrition by subjective global assessment, overweight was observed in 8.2% of patients, as well as Obesity and Normopese in 6.1%. After associating the nutritional intervention that the interned patients received, association could be evidenced in those who remained less interned, on the other hand, there was no relationship between age, weight and body mass index with hospital stay. It could be demonstrated that nutritional intervention through nutritional support can favor the improvement of the patient and a lower hospital stay, however, it cannot be widely confirmed by the reduced number of records to which it could be accessed.
RESUMO
INTRODUCTION: Patients with psoriatic arthritis have some lipid metabolism changes and higher risk of metabolic syndrome (MetS) and cardiovascular diseases, regardless of traditional risk factors, suggesting that chronic inflammation itself plays a central role concerning the atherosclerosis. However, there is a lack of information regarding atherogenic pattern and lipoprotein subfractions burden in these individuals. AIM: To evaluate the HDL and LDL-cholesterol plasmatic levels and their subfractions after a nutritional intervention in patients with psoriatic arthritis (PsA). METHODS: This was a randomized, placebo-controlled clinical trial of a 12-week nutritional intervention. PsA patients were randomly assigned to 1-Placebo: 1 g of soybean oil daily, no dietetic intervention; 2-Diet + Supplementation: an individualized diet, supplemented with 604 mg of omega-3 fatty acids, three times a day; and 3-Diet + Placebo: individualized diet + 1 g of soybean oil. The LDL subfractions were classified as non-atherogenic (NAth), atherogenic (Ath) or highly atherogenic (HAth), whereas the HDL subfractions were classified as small, medium, or large particles, according to the current recommendation based on lipoproteins electrophoresis. RESULTS: A total of 91 patients were included in the study. About 62% of patients (n = 56) had an Ath or HAth profile and the main risk factors associated were male gender, longer skin disease duration and higher BMI. Thirty-two patients (35%) had a high-risk lipoprotein profile despite having LDL plasmatic levels below 100 mg/dL. The 12-week nutritional intervention did not alter the LDL subfractions. However, there were significant improvement of HDL subfractions. CONCLUSION: Recognizing the pro-atherogenic subfractions LDL pattern could be a relevant strategy for identifying PsA patients with higher cardiovascular risk, regardless total LDL plasmatic levels and disease activity. In addition, a short-term nutritional intervention based on supervised and individualized diet added to omega-3 fatty acids changed positively the HDLLARGE subfractions, while LDLLARGE subfraction was improved in hypercholesterolemic individuals.

INTRODUCTION: Nutritional management plays a crucial role in treating patients with type 2 diabetes (T2D), working to prevent and control the progression of chronic non-communicable diseases. OBJECTIVES: To evaluate the effects of individualized nutritional interventions on weight, body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR), fasting blood glucose (FBG), hemoglobin A1c (HbA1c), total cholesterol (TC), LDL cholesterol (LDL-C), HDL cholesterol (HDL-C), triglycerides (TGs), systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR)} over 12 months and subsequently at follow-up (15 months). METHODS: This longitudinal experimental study (without randomization and blinding) enrolled 84 sedentary participants with T2D (both sexes, aged 18-80 years). They were divided into a control group of 40 participants who received only medical consultations, and an intervention group of 44 participants who received the same medical care along with a nutritional assessment. Consultations occurred quarterly from August 2020 to November 2022 (first-twelfth month), with six to nine patients per session. Subsequently, a follow-up was conducted from December 2022 to November 2023, during which the intervention group had only medical care (during the 12th-15th months). Personalized dietary planning was inspired by the Mediterranean/DASH diets adapted to Brazilian foods and socioeconomic cultures. STATISTICAL ANALYSIS: Normal variables were compared between groups for each time point and also within each group across different time points using a two-way ANOVA (repeated measures for intragroup) followed by the Sídák post hoc test. Non-normal variables were compared between groups for each time point using Kruskal-Wallis followed by the Dunn post hoc test, and within each group across different time points using Friedman followed by the Dunn post hoc test. Data with a Gaussian distribution were presented as mean ± standard deviation (SD), and data with a non-Gaussian distribution were presented as median ± interquartile range (IQR). For all cases, α < 0.05 and p < 0.05 were adopted. RESULTS: In the intervention group, significant reductions were observed between the first and twelfth month for all parameters (p < 0.05), (except for TC), along with an increase in HDL-C (p = 0.0105). Conversely, in the control group, there was a significant increase in HbA1c, weight, BMI, FBG, and WHR (p < 0.05) between the first and twelfth months. Regarding the comparison between groups, there was a significant difference for all analyzed parameters (p < 0.05) from the first to the twelfth month. In the follow-up, differences were also observed (p < 0.05), except for BMI (p > 0.05). CONCLUSION: The individualized nutritional intervention improved eating habits, anthropometric, biochemical, and cardiovascular markers in T2D over 12 months, with sustained results during follow-up. The dietary plan inspired by the Mediterranean and DASH diets demonstrated good adaptation to the Brazilian food culture and the patients' socioeconomic contexts. Consistent monitoring and personalized nutritional management are essential for optimizing long-term outcomes. However, more clinical trials are necessary in order to optimize the level of evidence for longitudinal interventions.

BACKGROUND: Inadequate food intake contributes to malnutrition in patients with cirrhosis on the waiting list for liver transplantation (LTx). OBJECTIVE: To evaluate food intake during 12 weeks of nutritional follow-up and assess factors independently associated with the difference between energy and protein intake in LTx patients. METHODS: A secondary analysis of data from a randomized controlled trial that evaluated the effects of Beta-Hydroxy-Beta-Methylbutyrate (HMB) supplementation and nutritional intervention in patients on a liver transplant waiting list. Dietary guidelines for patients with cirrhosis were used to prescribe the nutritional plan (35 kcal/kg; 1.5 g/kg dry weight for protein) and to evaluate the nutritional goals (30 kcal/kg; 1.2 g/kg dry weight for protein; late evening snack) and nutritional counseling dietary follow-ups were performed in each evaluation. Food intake was assessed in six moments: Baseline, week 0 (W0), week 2 (W2), week 4 (W4), week 8 (W8), and week 12 (W12). RESULTS: Forty-seven patients (55.0 ± 10.6y; 72.3% male) were evaluated. Only 25.5% (n = 12) of patients achieved nutritional goals at the end of the study. The mean energy intake at Baseline was 1782 ± 784 kcal (27.6 ± 13.2 kcal/kg) without difference between moments. The protein intake increased between W0 [63.4 ± 29.8g; 0.8(0.2-2.2 g/kg)] and W8 [72.0 ± 28.0g; 1.0(0.4-2.6 g/kg); p = 0.03; p = 0.03, respectively]. The consumption of cholesterol, calcium, phosphorus, magnesium, iron, and niacin increased (p < 0.05), as well as the consumption of legumes; roots and tubers; dairy; and meat, poultry and fish groups through time (p < 0.05). The percentage of patients that consumed a late evening snack rised from 40.4% (Baseline) to 76.6% (W8) (p < 0.001). The presence of ascites, nourished patients, frailty index classification, short physical performance battery score, systemic symptoms, and emotional function in the Quality of Life Test were independently associated with the energy intake difference between W12 and Baseline (p < 0.05). Diabetes mellitus, patients with moderately malnourishment, poor performance, fatigue, systemic symptoms, and emotional function in the Quality of Life Test were independently associated with the difference in protein intake between W12 and Baseline (p < 0.05). CONCLUSION: Patients on the liver transplant waiting list showed slight food intake improvement during the follow-up, but few met nutritional guidelines. Various clinical and nutritional factors independently affected energy and protein intake from W12 to Baseline.

INTRODUCTION: Binge eating disorder (BED) is a psychiatric illness related to a high frequency of episodes of binge eating, loss of control, body image dissatisfaction, and suffering caused by overeating. It is estimated that 30% of patients with BED are affected by obesity. "Mindful eating" (ME) is a promising new eating technique that can improve self-control and good food choices, helping to increase awareness about the triggers of binge eating episodes and intuitive eating training. OBJECTIVES: To analyze the impact of ME on episodes of binge eating, body image dissatisfaction, quality of life, eating habits, and anthropometric data [weight, Body Mass Index (BMI), and waist circumference] in patients with obesity and BED. METHOD: This quantitative, prospective, longitudinal, and experimental study recruited 82 patients diagnosed with obesity and BED. The intervention was divided into eight individual weekly meetings, guided by ME sessions, nutritional educational dynamics, cooking workshops, food sensory analyses, and applications of questionnaires [Body Shape Questionnaire (BSQ); Binge Eating Scale (BES); Quality of Life Scale (WHOQOL-BREF)]. There was no dietary prescription for calories, carbohydrates, proteins, fats, and fiber. Patients were only encouraged to consume fewer ultra-processed foods and more natural and minimally processed foods. The meetings occurred from October to November 2023. STATISTICAL ANALYSIS: To carry out inferential statistics, the Shapiro-Wilk test was used to verify the normality of variable distribution. All variables were identified as non-normal distribution and were compared between the first and the eighth week using a two-tailed Wilcoxon test. Non-Gaussian data were represented by median ± interquartile range (IQR). Additionally, α < 0.05 and p < 0.05 were adopted. RESULTS: Significant reductions were found from the first to the eighth week for weight, BMI, waist circumference, episodes of binge eating, BSQ scale score, BES score, and total energy value (all p < 0.0001). In contrast, there was a significant increase in the WHOQOL-BREF score and daily water intake (p < 0.0001). CONCLUSIONS: ME improved anthropometric data, episodes of binge eating, body image dissatisfaction, eating habits, and quality of life in participants with obesity and BED in the short-term. However, an extension of the project will be necessary to analyze the impact of the intervention in the long-term.

In a study addressing the high risk of chronic diseases in people with diabetes and obesity linked to metabolic syndrome, the impact of a Golden Berry diet was investigated using a diabetic animal model. Obese rats with diabetic characteristics were fed a diet containing five percent Golden Berry for 16 days. This study focused on various parameters including organ weights, expression of metabolic genes, and urinary biomarkers. Post-Golden Berry intake, there was a notable decrease in the body, liver, pancreas, visceral, and subcutaneous adipose tissue weights in these obese, hyperglycemic rats. In contrast, an increase in brown adipose tissue (BAT) cell mass was observed. This diet also resulted in reduced blood glucose levels and normalized plasma biochemical profiles, including cholesterol, triglycerides, LDL, and HDL levels. Additionally, it modulated specific urinary biomarkers, particularly pipe-colic acid, a primary marker for type 2 diabetes. Bioinformatics analysis linked these dietary effects to improved insulin signaling and adipogenesis. Regular consumption of Golden Berry effectively prevented insulin resistance and obesity in rats, underscoring its significant health benefits and the protective role of an antioxidant-rich diet against metabolic syndrome. These findings offer promising insights for future therapeutic strategies to manage and prevent obesity and related chronic diseases.

Strategies to address the nutritional needs of adolescent girls and young women often focus on supplementation. In this study, an action-research approach involving a nutrition education and entrepreneurship intervention was carried out among adolescent girls and young women in poor neighborhoods of Medellín, Colombia. The intervention group significantly increased its intake of several nutrients, including energy, protein, total fat, saturated fat, monounsaturated fat, polyunsaturated fat, cholesterol, dietary fiber, calcium, zinc, and vitamins A, B2, B3, B9, and C. A significant increase was observed in the intake of the Global Diet Quality Score (GDQS) healthy food groups (other fruits, other vegetables, legumes, high-fat dairy products), accompanied by a decrease in the consumption of some unhealthy food groups (sweets and ice creams). A multivariate regression controlling for age, socioeconomic status, occupation, Household Hunger Scale, mean probability of adequacy, physical activity, and body self-perception showed that the nutrition intervention improved the total GDQS by 33% in the intervention group-a substantial improvement notwithstanding the study group's precarious social and economic conditions. We conclude that nutrition education and entrepreneurship models based on this approach may improve the dietary profile of this population and reduce future pressures from nutrition-related chronic diseases.
RESUMO
Fetal programming provides explanatory mechanisms for the currently high prevalence of gestational obesity. The endocannabinoid system (ECS) participates in the regulation of energy balance, and with a high-fat diet (HFD), it is overactivated. The aim of this study was to determine the effects of a nutritional intervention during pregnancy and lactation on obese female progenitors, on metabolic alterations of the offspring and on the involvement of ECS. Female mice (C57/BL/6-F0), 45 days old, and their offspring (males) were separated according to type of diet before and during gestation and lactation: CON-F1: control diet; HFD-F1 group: HFD (fat: 60% Kcal); INT-F1 group: HFD until mating and control diet (fat: 10% Kcal) afterward. Glucose tolerance and insulin sensitivity (IS) were tested at 2 and 4 months. At 120 days, mice were sacrificed, plasma was extracted for the determination of hormones, and livers for gene expression and the protein level determination of ECS components. INT-F1 group presented a lower IS compared to CON-F1, and normal levels of adiponectin and corticosterone in relation to the HFD-F1 group. The intervention increased hepatic gene expression for fatty-acid amide hydrolase and monoacylglycerol lipase enzymes; however, these differences were not observed at the protein expression level. Our results suggest that this intervention model normalized some hormonal parameters and hepatic mRNA levels of ECS components that were altered in the offspring of progenitors with pre-pregnancy obesity.

To evaluate the effectiveness of a collective intervention to encourage the consumption of fruits and vegetables on the nutrients intake for the prevention of chronic non-communicable diseases (NCDs), a randomized controlled community trial was conducted with a representative sample from the Health Academy Program. While the individuals in the control group (CG) participated in regular physical exercise, those in the intervention group (IG) also participated in a collective intervention. After 12 months, IG and CG showed a reduction in energy, omega 3 and sodium intake and an increase in the consumption of carbohydrates, fiber, vitamins, and minerals. Individuals from the CG showed an increase in phosphorus consumption and, in the IG, a reduction in the consumption of total, saturated, and polyunsaturated fats as well as an increase in the consumption of monounsaturated fats was seen. In both groups, there was an increase in the prevalence of adequate nutrients. Participation in the nutritional intervention was associated with lower consumption of energy and protein in the diet. The results pointed to the importance of individuals' participation in the program, which, associated with nutritional intervention, promoted an improvement in the nutrient profile of the diet and the prevention and control of NCDs.

Lipids represent one out of three major macronutrient classes in the human diet. It is estimated to account for about 15-20% of the total dietary intake. Triacylglycerides comprise the majority of them, estimated 90-95%. Other lipid classes include free fatty acids, phospholipids, cholesterol, and plant sterols as minor components. Various methods are used for the characterization of nutritional lipids, however, lipidomics approaches become increasingly attractive for this purpose due to their wide coverage, comprehensiveness and holistic view on composition. In this chapter, analytical methodologies and workflows utilized for lipidomics profiling of food samples are outlined with focus on mass spectrometry-based assays. The chapter describes common lipid extraction protocols, the distinct instrumental mass-spectrometry based analytical platforms for data acquisition, chromatographic and ion-mobility spectrometry methods for lipid separation, briefly mentions alternative methods such as gas chromatography for fatty acid profiling and mass spectrometry imaging. Critical issues of important steps of lipidomics workflows such as structural annotation and identification, quantification and quality assurance are discussed as well. Applications reported over the period of the last 5years are summarized covering the discovery of new lipids in foodstuff, differential profiling approaches for comparing samples from different origin, species, varieties, cultivars and breeds, and for food processing quality control. Lipidomics as a powerful tool for personalized nutrition and nutritional intervention studies is briefly discussed as well. It is expected that this field is significantly growing in the near future and this chapter gives a short insight into the power of nutritional lipidomics approaches.

To evaluate the effect of dietary interventions aimed at weight loss in gastroesophageal reflux disease (GERD) symptoms and general health-related quality of life (HRQL) in overweight and obese patients. A population of GERD patients were randomized into two groups: the intervention group received individualized dietary counselling on scheduled appointments throughout 6 months of follow-up (n = 31) and the control group received only informative dietary guidelines on baseline (n = 31). Anthropometric data were monthly collected, and the HRQL score for GERD (GERD-HRQL) and the Health Survey (SF-36) questionnaires were applied on baseline and reevaluated at the end of follow-up. Dietary intervention led to an average weight loss of 4.4 kg (±5.3) and an average BMI reduction of 1.7 kg/m2 (±2.9) compared to an increase in weight of 2.1 kg (±4.4) (p < .001) and an increase in BMI of 1.3 (±6.3) (p = 0.023) in the control group. Individuals in the intervention group had a mean decrease in symptoms of 6.8 (±5.5) points while the control group had worsening of their symptoms with an increase of 3.3 (±4) points (p < .001) in the disease-specific questionnaire. There was a positive association between weight loss and reduction of symptoms as measured by the GERD-HRQL score (r = .49; p < .001). Dietary intervention for 6 months with an individualized low-calorie diet program produces weight loss and a significant improvement in GERD-related symptoms, as well as in HRQL.

RESUMO
Nutrition is an essential component when promoting human health. Without a doubt, improving the quality of one's diet can improve one's quality of life as a whole and help postpone the onset or control of many chronic diseases. The volume of publications in this field has increased in recent years, in line with increased awareness of the importance of nutrition in health; however, the quality of the evidence on which most nutritional guidelines are based remains low, due to errors in conducting nutritional interventions or because the information is primarily derived from observational studies. To enhance the evidence supporting clinical guidelines in nutrition, the quality of randomized clinical trials (RCT) based on nutritional interventions must be improved; nevertheless, due to their heterogeneous nature and a lack of specific guidelines for designing, performing, documenting, and reporting on this type of intervention, conducting a nutritional intervention is a real challenge. Following a review of the literature on the methodological and ethical standards, as well as four extensions of the CONSORT (Consolidated Standards of Reporting Trials) guidelines that should be considered when implementing a nutritional intervention, seven essential aspects were identified. The current narrative review includes definitions, examples, diagrams, and algorithms regarding aspects of the appropriate study design, the intervention of the control group, the randomization and blinding processes, the study population selection, as well as a description of the type of intervention and the personnel involved in carrying out the study in order to make the implementation of a nutritional intervention easier.

RESUMO
AIMS: This study aimed to evaluate the impact of a 12-week calorie-restricted diet and recreational sports training on gene expressions IL-15, ATROGIN-1 and MURF-1 in skeletal muscle of T2D patients. METHODS: Older adults with T2D (n = 39, 60 ± 6.0 years, BMI 33.5 ± 0.6 kg/m2) were randomly allocated to Diet+Soccer (DS), Diet+Running (DR) or Diet (D). The training sessions were moderate-to-high-intensity and performed 3 × 40 min/week for 12-weeks. Gene expression from vastus lateralis muscle obtained by qRT-PCR, dual-energy X-ray and fasting blood testing measurements were performed before and after 12-weeks. Statistical analysis adopted were two-way ANOVA and Paired t-test for gene expression, and RM-ANOVA test for the remainder variables. RESULTS: Total body weight was reduced in ~4 kg representing body fat mass in all groups after 12-weeks (P < 0.05). HbA1c values decreased in all groups post-intervention. Lipids profile improved in the training groups (P < 0.05) after 12-weeks. ATROGIN-1 and MURF-1 mRNA reduced in the DS (1.084 ± 0.14 vs. 0.754 ± 1.14 and 1.175 ± 0.34 vs. 0.693 ± 0.12, respectively; P < 0.05), while IL-15 mRNA increased in the DR (1.056 ± 0.12 vs. 1.308 ± 0.13; P < 0.05) after 12-weeks intervention. CONCLUSION: Recreational training with a moderate calorie-restricted diet can downregulates the expression of atrophy-associated myokines and increases the expression of anti-inflammatory gene IL-15.

ABSTRACT Background Malnutrition is common in liver cirrhosis patients that is correlated with early complications, morbidity and mortality. Objective The purpose of the study was to assess nutritional status, impact of nutritional screening and intervention in liver cirrhosis patients by evaluating their actual energy and protein intake during hospital stay. Methods A cross sectional study was conducted wherein all patients' nutritional status was defined by Subjective Global Assessment tool. Adequate energy and protein supply were planned and executed by using individualized nutritional plan for patients with dietitian's collaboration. Anthropometric measurements included height, weight, body mass index, mid upper arm circumference, hand grip strength and triceps skin-fold thickness. Biochemical tests included haemoglobin, mean corpuscular haemoglobin, volume and concentration, albumin and liver function tests. To record the daily food intake, a 24-hour dietary recall was used. Results Overall 83 patients (mean age 55) were included, among them 46% of patients were moderately malnourished, 12% were normal, while 42% of cirrhotic patients were severely depleted according to Subjective Global Assessment. The mean intake of calories and protein was improved during stay in hospital after nutritional intervention and critical monitoring (P<0.05). Anthropometric measurements at baseline and discharge showed significant differences (P <0.05) in weight, body mass index, triceps skin fold thickness and mid upper arm circumference values, but not in hand grip strength that was associated with malnourishment among patients. Conclusion Providing individualized nutritional intervention and its monitoring by qualified dietitians during hospital stay helps to improve intake in patients that prevent further risk of malnutrition and related complications.
RESUMO Contexto A desnutrição é comum em pacientes com cirrose hepática e está correlacionada com complicações precoces, morbidade e mortalidade. Objetivo O objetivo do estudo foi avaliar o estado nutricional, o impacto da triagem nutricional e a intervenção em pacientes com cirrose hepática, avaliando sua ingestão real de energia e proteína durante a internação hospitalar. Métodos Foi realizado um estudo transversal em que o estado nutricional de todos os pacientes foi definido pela ferramenta de Avaliação Global Subjetiva. O fornecimento adequado de energia e proteína foi planejado e executado por meio de plano nutricional individualizado para pacientes com colaboração de nutricionista. As medidas antropométricas incluíram: altura, peso, índice de massa corporal, circunferência do braço médio, força de aderência da mão e espessura da dobra da pele tríceps. Os testes bioquímicos incluíram: hemoglobina, volume e concentração da hemoglobina corpuscular média, albumina e testes de função hepática. Para registrar a ingestão diária de alimentos, foi utilizado um recall dietético de 24 horas. Resultados Ao todo foram incluídos 83 pacientes (média de 55 anos), entre eles 46% dos pacientes estavam moderadamente desnutridos, 12% estavam normais, enquanto 42% dos pacientes cirróticos estavam severamente depletados de acordo com a Avaliação Global Subjetiva. A ingestão média de calorias e proteínas foi melhorada durante a internação hospitalar após intervenção nutricional e monitoramento crítico (P<0,05). As medidas antropométricas na linha de base e descarga apresentaram diferenças significativas (P< 0,05) em peso, índice de massa corporal, espessura da dobra da pele do tríceps e valores médios de circunferência do braço, mas não na força de aderência da mão que estava associada à desnutrição entre os pacientes. Conclusão Proporcionar intervenção nutricional individualizada e seu acompanhamento por nutricionistas qualificados durante a internação hospitalar ajuda a melhorar a ingestão em pacientes que previnem maior risco de desnutrição e complicações relacionadas.
RESUMO
We analyzed the effectiveness of two nutritional interventions alone and together, EVOO and the DieTBra, on the inflammatory profile of severely obese individuals. This study was an RCT with 149 individuals aged from 18 to 65 years, with a body mass index ≥ 35 kg/m2, randomized into three intervention groups: (1) 52 mL/day of EVOO (n = 50); (2) DieTBra (n = 49); and (3) DieTBra plus 52 mL/day of EVOO (DieTBra + EVOO, n = 50). The primary outcomes we measured were the-neutrophil-to-lymphocyte ratio (NLR) and the secondary outcomes we measured were the lymphocyte-to-monocyte ratio (LMR); leukocytes; and C reactive protein (CRP). After 12 weeks of intervention, DieTBra + EVOO significantly reduced the total leucocytes (p = 0.037) and LMR (p = 0.008). No statistically significant differences were found for the NLR in neither the intra-group and inter-group analyses, although a slight reduction was found in the DieTBra group (-0.22 ± 1.87). We observed reductions in the total leukocytes and LMR in the three groups, though without statistical difference between groups. In conclusion, nutritional intervention with DietBra + EVOO promotes a significant reduction in inflammatory biomarkers, namely leukocytes and LMR. CRP was reduced in EVOO and DieTBra groups and NLR reduced in the DieTBra group. This study was registered at ClinicalTrials.gov under NCT02463435.

PURPOSE: Golden berry (Physalis peruviana L.) is an exotic fruit exported from Colombia to different countries around the world. A review of the literature tends to demonstrate a hypoglycaemic effect with an improvement in insulin sensitivity after oral ingestion of fruit extracts in animal models. However, little is known about their potential effects in humans, and very little is known about the mechanisms involved. This study aimed at identifying discriminant metabolites after acute and chronic intake of golden berry. METHOD: An untargeted metabolomics strategy using high-performance chemical isotope-labelling LC-MS was applied. The blood samples of eighteen healthy adults were analysed at baseline, at 6 h after the intake of 250 g of golden berry (acute intervention), and after 19 days of daily consumption of 150 g (medium-term intervention). RESULTS: Forty-nine and 36 discriminant metabolites were identified with high confidence, respectively, after the acute and medium-term interventions. Taking into account up- and downregulated metabolites, three biological networks mainly involving insulin, epidermal growth factor receptor (EGFR), and the phosphatidylinositol 3-kinase pathway (PI3K/Akt/mTOR) were identified. CONCLUSIONS: The biological intracellular networks identified are highly interconnected with the insulin signalling pathway, showing that berry intake may be associated with insulin signalling, which could reduce some risk factors related to metabolic syndrome.

The objective of this review is to present the impact of nutritional education, physical activity and support network interventions on the nutritional status, cognitive and academic achievement of students under 18 years of age. According to the literature, multicomponent interventions that address diet, physical activity, and involve parents concluded to be more effective in combating obesity and enhancing academic achievement in young people. Therefore, the implementation of public policies that commit to intervene in a timely manner in the first stages of the life cycle, would have a considerably beneficial impact on health(AU)

ABSTRACT Background: There is very low-quality evidence that the transtheoretical stages of change model combined with physical activity or diet, or both, can result in significant improvements in dietary and physical activity habits. Objective: To evaluate the association between stages of change on weight reduction, after a nutritional intervention, in patients with cardiovascular risk. Methods: In a randomized controlled clinical trial, patients >18 years old with body mass index ≥25 kg/m2 and at least two cardiovascular risk factors were distributed to an intervention or control group. The intervention group received, according to stage of change, a multidisciplinary intervention formed by a nutritionist, a psychologist, a chef and a physiotherapist to improve healthy eating, while the control group was given a nutritional prescription. Stage of change from the transtheoretical model, anthropometric variables, physical activity, and 24-hour recall of food intake were measured at baseline and 12 months postintervention. The main outcomes were change in weight, waist and hip circumferences. Results: We included 188 subjects (intervention group= 93, control group= 95), where 75% were female, 68.6% had obesity, and mean age 50.3±13. After 12-months, subjects in the intervention group that were ready to change showed a greater decrease in weight and energy intake, with differences between ready to change vs not ready to change subjects and an interaction between intervention group and ready to change. Conclusions: An intervention with a multidisciplinary team can be as effective as the current standard of care in promoting weight loss when taking into account baseline stage of change.
RESUMEN Introducción: existe poca evidencia sobre el efecto de la etapa de cambio del modelo transteórico en conjunto con actividad física, dieta, o ambas, en los hábitos dietéticos y de actividad física. Objetivo: evaluar el efecto de una intervención nutricional y la etapa de cambio inicial sobre la reducción de peso después de una intervención nutricional en pacientes con riesgo cardiovascular. Métodos: Ensayo clínico controlado aleatorizado. Pacientes >18 años con índice de masa corporal ≥25 kg/m2 y al menos 2 factores de riesgo cardiovascular fueron asignados a: grupo intervención o grupo control. El grupo de intervención recibió de acuerdo a la etapa de cambio una intervención multidisciplinaria formada por: nutricionista, psicólogo, chef y fisioterapeuta, mientras que el grupo control solo recibió prescripción nutricional habitual. Se evaluaron al inicio del estudio y 12 meses después de la intervención: etapa de cambio del modelo transteórico, variables antropométricas, actividad física y recordatorio de 24 horas. Resultados: se incluyeron 188 sujetos (grupo intervención 93, grupo control 95), 75% eran mujeres, 68,6% tenían obesidad, con promedio de 50.3±13. Después de 12 meses, los sujetos en el grupo de intervención que estaban listos para el cambio, mostraron una mayor disminución en el peso y en el consumo calórico, con diferencias estadísticamente significativas en la interacción grupo y etapa de cambio. Conclusiones: Una intervención con un equipo multidisciplinario puede ser tan eficaz como el tratamiento habitual para promover la pérdida de peso cuando se tiene en cuenta la etapa de cambio basal.
