Introduction: Parkinson's disease (PD) is the second most common neurodegenerative disorder worldwide. It has been demonstrated that there is a correlation between the increase in bacterial abundance and the severity of certain symptoms associated with PD.

Aim: the aim of this pilot study was to analyze the effect of supplementation with prebiotic fiber on the gut microbiota (GM) and nutritional status of elderly volunteers with Parkinson's disease.

Methodology: this is a pilot study of pre and post intervention with prebiotic fiber. All subjects involved were volunteers with PD, who were given nutritional counseling and gut microbiota measured on time cero and after 30 days of prebiotic fiber intervention.

Results: a statistically significant difference was found in calf circumference (p 0.0422) after the intervention with prebiotic fiber. GM analyses show an initial difference in gut bacterial abundance of older people with PD and people without PD. Furthermore, our results showed a difference in bacterial families and genera after the supplementation with prebiotic fiber. in addition, we found a statistically significant difference in the val-ue of circumference calf and a trend in the improvement of body weight, Body mass index (BMI), neck circumference, arm circumference, brachial area, and Diet Quality Questionnaire (DQQ) for older adults.

Conclusion: supplementation with 20 g of prebiotic fiber for 30 days could modify the intestinal microbiota, reducing bacterial genera and phylum that are abundant in Park-inson's disease, such as Verrucomicrobia. Therefore, the use of prebiotic fiber could represent an alternative to improve intestinal health and nutritional status of people with Parkinson's disease.

Objective: to systematically evaluate the efficacy and safety of Intermittent Fasting (IF) in patients with type 2 diabetes (T2DM).

Method: randomized controlled trials (RCTs) on the efficacy of IF intervention in T2DM were systematically searched from PubMed, The Cochrane Library, Web of Science, MEDLINE and CNKI, and retrieval time was set from database onset to September 2024. A meta-analysis was performed using the RevMan 5.3 software.

Results: sixteen articles were included, with a total of 5369 patients. The meta-analysis showed that, compared with the control group, IF could improve patients' glycated hemoglobin, fasting plasma glucose, body weight, BMI, waist circumference, systolic blood pressure, diastolic blood pressure, low density lipoprotein, and cholesterol levels (p < 0.05). However, there was no significant difference in improving the levels of postprandial plasma glucose, high-density lipoprotein, and triglyceride levels compared to the control group (p > 0.05).

Conclusion: IF may help people with T2DM manage their blood sugar levels effectively. In addition, IF can reduce body weight, reduce waist circumference, maintain stable blood pressure, and reduce low-density lipoprotein and total cholesterol levels, and is considered safe and feasible to implement. However, more high-quality studies are needed to provide further evidence on the benefits of IF in improving other lipid levels.

Background: social networks have become indispensable for global communication, offering unparalleled access to information. However, the lack of content regulation has allowed health and nutrition misinformation to thrive, posing significant public health risks.

Objectives: this study aimed to identify the social networks most frequently used for spreading nutrition-related misinformation and evaluate the primary topics, including diseases and dietary claims, featured in these messages.

Methods: a systematic review of the literature was conducted, analyzing studies focused on nutrition-related misinformation across platforms such as Twitter, Instagram, TikTok, and YouTube. Data collection adhered to PRISMA guidelines, and findings were synthesized narratively to address the study objectives.

Results: this study analyzed 28 documents focusing on nutrition-related misinformation on social networks. Instagram (50 %) and YouTube (39.28 %) were identified as the most prevalent platforms for spreading such content, followed by TikTok (5.13 %) and Twitter (10.72 %). Over 62 % of the reviewed studies addressed misinformation linked to miracle diets, often associated with orthorexia (14.28 %) and COVID-19 (14.28 %). These diets frequently included unverified claims of rapid health improvements. Notably, credible nutrition content was predominantly shared by healthcare professionals and academic organizations, highlighting their key role in fight against misinformation.

Conclusions: misinformation about nutrition on social networks is a growing public health concern. Public health institutions must implement strategies to improve digital literacy and provide tools for assessing information credibility. Healthcare professionals should leverage social media to disseminate evidence-based knowledge, counteracting the influence of unreliable sources. Collaborative efforts are essential to ensure social networks serve as platforms for reliable health promotion and education.

Introduction: food contains both inflammatory and anti-inflammatory components. The higher the concentration of inflammatory components, the greater the likelihood of developing obesity and other chronic conditions linked to low-grade chronic inflammation. Consequently, various indices have been developed to quantify dietary inflammation, such as the Empirical Dietary Inflammatory Pattern (EDIP-SP), which has been validated in Brazil. This study aimed to examine the potential association between EDIP-SP and the nutritional status of college students.

Methodology: the study involved 97 undergraduate nutrition students from Fortaleza, Ceará, in Northeast Brazil. Participants completed a food frequency questionnaire to assess their intake of EDIP-SP components, including processed meats, vegetables, fruits, rice, and beans. Anthropometric measurements (weight, height, and waist circumference) were taken to calculate body mass index (BMI) and to categorize nutritional status and abdominal adiposity.

Results: the diet consumed by the participants was primarily anti-inflammatory, with a mean score of -1.57 ± 0.69. Most participants were not classified as overweight (59.79 %) and did not exhibit abdominal adiposity (91.75 %). No significant association was observed between EDIP-SP scores and BMI (r = -0.11; p = 0.297) or waist circumference (r = -0.07; p = 0.489). However, a weak but direct association was found between the inflammatory score of processed meat intake and abdominal adiposity in female participants (r = 0.27; p = 0.019).

Conclusion: the Empirical Dietary Inflammation Pattern (EDIP-SP) does not appear to significantly influence the nutritional status of students. Nevertheless, the inflammatory impact of processed meat intake may contribute to excess abdominal adiposity, particularly among women.

Introduction: this study focuses on Home Enteral Nutrition (HEN), whose use has grown enormously in recent years.

Objective: to analyze the prescriptions and, in addition, determine whether National Health System (NHS) funding criteria are met and to explore whether overcosts exist.

Methods: a retrospective observational study was conducted on 844 patients (895 episodes) who received HEN, using information obtained from the healthcare database. Demographic, clinical, dietary, and economic data were analyzed.

Results: in 9.7 % of the episodes analyzed, the funding criteria were met; in 15.1 %, ≥ 50 % kcal/day required was provided through HEN. During the 3 months of the study an average of 118.1 ± 86.8 units/patient were dispensed, which resulted in an average monthly expenditure of € 69.9 ± 66.3/patient. To go to the hospital to collect HEN, an average of 78.1 ± 69.5 km/patient was traveled, with an associated average monthly fuel cost of € 2.65 ± 2.39/patient. The additional expenditure associated with prescriptions not aligned with the funding criteria was estimated at € 574,259.44/year in the health area analyzed, with a quota of 200,000 inhabitants.

Conclusions: the results of this study show a divergence in the use of HEN compared to the conditions established by the NHS for the funding of this treatment. Given the low compliance rate and the current scientific evidence on the use of HEN, it may be necessary to re-evaluate the funding criteria to make them more representative of clinical evidence and actual practice.

Introduction: nutritional screening (NS) is crucial for early detection of malnutrition (MN) and prediction of "nutritional risk".

Objectives: to establish the prevalence of hospital malnutrition by Subjective Global Assessment (SGA) and evaluate the agreement of NS tools and their ability to predict mortality (M), infectious (IC) and non-infectious complications, and prolonged stay (> 11 days).

Methods: a multicenter, prospective, observational study was conducted. Nutritional status was assessed with SGA and simultaneously measured with Malnutrition Screening Tool (MST), Short Nutritional Assessment Questionnaire (SNAQ), Malnutrition Universal Screening Tool (MUST), Nutrition Risk Screening (NRS-2002), and Mini Nutritional Assessment Short Form (MNA-SF). All methods were classified into three categories for equivalence with SGA. Kappa was used to assess agreement and logistic regression, sensitivity, specificity, and area under the ROC curve for predictive ability.

Results: a total of 1546 patients from 64 hospitals in Argentina were included, 52.6 % male, median age 58 years. According to SGA, hospital malnutrition prevalence was 48.06 % (95 % CI 45.57; 50.55), with 37 % moderately malnourished (B) and 11 % severely malnourished (C). MST showed the best agreement with SGA (k 0.41), and among methods, MST with SNAQ (k 0.52). Adverse outcomes were associated with MN by any method. SGA, MNA-SF, and NRS-2002 had the best predictive ability (ROC area 0.74 to 0.72 for M). IC were the hardest to predict (maximum ROC area 0.62). Sensitivities ranged from 60 to 96 %, and specificities were above 90 % for MN by SGA.

Conclusions: variations in predictive ability among NS methods do not affect their clinical applicability.

Introduction: the Dietary Inflammatory Index (DII) provides a quantitative means for assessing the role of diet in relation to health outcomes.

Objetive: this study aimed to assess the association between the inflammatory potential of diet, as measured by the DII and IL-17A levels in young adults.

Methods: a cross-sectional study was conducted on 69 adults between 18-35 y of age in San Luis Potosi, Mexico. Fasting blood samples were collected to analyze lipid profile, glucose homeostasis, and IL-17A. Dietary intake was assessed using a 24-hour recall. DII scores were calculated from 19 available food parameters. Univariate linear regression models were estimated to evaluate the possible dependence of IL-17A levels (dependent variables) on some potential explicative variables such as anthropometric, clinical, biochemical, and dietary variables.

Results: there was a high inflammatory potential, with a mean DII score of +1.04 (range: -2.19 to +2.78). The DII was not associated with BMI, IL-17A levels or cardiometabolic risk factors.

Conclusion: the study shows that the diets of healthy college-aged Mexican adults had a high inflammatory potential.
