The goal of this study is to compare pain levels in individuals with Sickle Cell Disease while following the Mediterranean Diet to pain levels while following their usual diet.

ENERGY2MOB STUDY: OBESITY MANAGEMENT IN BERGUEDÀ

Background: Obesity is a prevalent multifactorial disease worldwide and has become a significant public health concern. The latest data from the 2022 Catalonia Health Survey show that 56.2% of men and 43.7% of women are overweight or obese, and 39% of children aged 6 to 12 years have excess weight. Excess adiposity poses a health risk as it is associated with various chronic diseases such as type 2 diabetes mellitus, hypertension, and dyslipidaemia, all of which affect quality of life and increase mortality risk. Hypothesis: The Energy2MOB obesity management programme in Berguedà is a group-based intervention incorporating nutrition education and physical activity. It aims to reduce excess body weight and the risk of chronic diseases, including type 2 diabetes mellitus, dyslipidaemia, and hypertension, through a multicomponent approach that enhances dietary habits, physical activity, and emotional eating regulation. Objectives * Assess the effectiveness of the Energy2MOB programme in reducing body weight by 5-10% among adults with obesity in the Berguedà health region. * Measure lifestyle modifications, including dietary habits, physical activity, and emotional eating. Methodology: A randomised clinical trial with two groups (control and intervention) over one year, including individuals aged 18-65 years in the Berguedà health region with overweight grade II (BMI 27-30 kg/m²) or obesity (BMI 30-40 kg/m²). Exclusion criteria include significant language barriers, previous bariatric surgery, moderate to severe cognitive impairment, and severe psychiatric disorders preventing participation in sessions. Participants must attend at least 80% of the programme. Measurements * Sociodemographic factors: sex, age, education level, marital status, employment status. * Lifestyle factors: alcohol and tobacco use, dietary habits, physical activity, emotional eating, health-related quality of life. * Anthropometric parameters: body weight, height, BMI, waist circumference. * Blood pressure, medication use, biochemical parameters (fasting glucose, glycated haemoglobin, lipid profile, liver and kidney function markers, C-reactive protein). Statistical Analysis: Accepting an alpha risk of 0.05 and a statistical power above 0.8 in a bilateral contrast, 68 subjects per group are required to detect a difference of at least 2.5 kg. A common standard deviation of 4.77 is assumed, with an estimated 15% dropout rate. Sample size calculations were performed using GRANMO version 8.0 (https://www.datarus.eu/ca/aplications/granmo/; consulted in November 2024). Expected Outcomes, Applicability, and Relevance: This study aims to generate scientific evidence on the effectiveness of multicomponent group-based interventions focused on improving nutrition, physical activity, and psychological well-being in obesity and chronic disease management. It seeks to create an environment that facilitates behavioural changes, leading to weight reduction and improved quality of life. The findings will also contribute to the development of a practical guide for addressing excess weight in primary healthcare settings. Keywords (maximum 6): Adult obesity, primary health care, group interventions, dietary interventions, multicomponent interventions, Mediterranean diet.

KETOgenic Diet Therapy in Patients With ACROmegaly

Acromegaly is caused by a tumour located at the base of the brain in the pituitary gland that produces too much growth hormone (GH). Symptoms caused by the excess of GH, and consequently increased insulin like growth factor 1 (IGF-1), are disproportionate growth of body parts, fluid retention, snoring and excessive perspiration. The various metabolic changes that occur due to acromegaly increase the risk for insulin resistance, diabetes mellitus, arterial hypertension, sleep apnoea and thus an increased risk of cardiovascular disease if left untreated. The result is signs and symptoms, increased mortality, morbidity, and greatly reduced quality of life (QoL). Normalisation of GH and IGF-1 gives a normalisation of mortality, however morbidity and QoL do not (completely) normalise. After surgery, a somatostatin analogue is the primary medical treatment, however, normalisation occurs in only 40% of patients. Recently, in a proof-of-principle study, the researchers showed that a 2-week ketogenic diet (low in carbohydrates) in patients with somatostatin analogues could significantly reduce IGF-1 values. Patients felt better and sometimes even needed less somatostatin analogues. This proof of concept led to the new hypothesis that acromegaly patients with somatostatin analogues should possibly be treated with a eucaloric low-carbohydrate ketogenic diet for a longer period of time to improve their biochemistry, symptoms and QoL. Additionally, this diet can make a significant contribution in the treatment of insulin resistance and glucose intolerance that often occur in this patient group.

GWAS to Identify Predictive Genetic Factors for the Success of Dietary Intervention in the Treatment of IBS Symptoms

This is a GWAS that aims to identify possible single nucleotide polymorphisms (SNPs) that are associated with the response in a combined dietary pattern low in fermentable oligosaccharides, disaccharides, monosaccharides, and polyols and Meditteranean diet (MED-LFD) in a small group of patients with Irritable Bowel Syndrome (IBS).

Impact of Mediterranean Diet in Cardiovascular Risk Among People With HIV

This study (VIHMET) aims to explore how dietary changes, specifically the adoption of a Mediterranean diet, can improve health outcomes in people living with HIV (PLWH) who are on antiretroviral therapy (ART). PLWH often experience chronic inflammation, metabolic disturbances, and elevated cardiovascular risk due to the virus, immune activation, and ART-related side effects. By examining dietary interventions, this study seeks strategies to reduce these risks and enhance quality of life. The VIHMET study is a randomized clinical trial involving 64 participants at Hospital del Mar, Barcelona, randomized into control and intervention groups (1:2 ratio). The intervention group will receive personalized nutritional counseling to improve adherence to the Mediterranean diet, focusing on food selection and meal preparation. The control group will follow standard dietary recommendations. Assessments will occur at baseline, week 24, and week 48. Key health indicators include lipid profiles, markers of inflammation, immune activation, and cardiovascular health, assessed through non-invasive techniques like arterial stiffness and subclinical atherosclerosis measurements. Participants will complete questionnaires on diet adherence, physical activity, and quality of life, alongside anthropometric evaluations. Eligible participants are adults with HIV, undetectable viral loads for 12+ months, and elevated LDL cholesterol with low Mediterranean diet adherence. Exclusion criteria include lipid-lowering drugs, chronic anti-inflammatory therapy, or other active inflammatory/metabolic conditions. This study aims to improve lipid levels, reduce inflammation, decrease arterial stiffness, and assess diet adherence's impact on quality of life and subclinical atherosclerosis. Results may inform dietary recommendations to reduce cardiovascular risks and enhance holistic care for PLWH.

Effectiveness of an App for Mobile Phones (e-12HR) to Increase Adherence to Mediterranean Diet in University Students

This is a controlled, randomized and multicentric clinical trial aimed at university students and performed at the Faculties of Medicine and Pharmacy at the University of Seville (Spain). Its objective is to evaluate the effect of an intervention based on the use of an information and communication technology (ICT) tool, specifically an application for mobile telephones (called e-12HR), in the improvement of adherence to the Mediterranean diet.
