Clinical trials

The purpose of this clinical trial is to evaluate whether a nutritional supplement containing resveratrol, quercetin, taurine, inulin, and whey protein improves biochemical and molecular markers, as well as clinical outcomes, in patients with liver disease related to chronic hepatitis C infection. The study will compare the investigational supplement with an active control (whey protein alone) to determine whether the combination formulation provides additional benefits on liver-related biomarkers and clinical assessment. Participants will: Take the investigational supplement or active control daily for 12 weeks. Attend clinic visits every 4 weeks for laboratory testing and clinical evaluations.

Metabolic syndrome is a cluster of risk factors, including abdominal obesity, high blood pressure, high triglycerides, and insulin resistance, that increase the risk of developing type 2 diabetes and cardiovascular disease. The prevalence of this syndrome is rising in Mexico. Recent research suggests that when we eat is as important as what we eat. Therefore, chrononutritional strategies such as time-restricted eating (TRE), where food intake is confined to a specific daily time window, have been developed and shown promising benefits. However, there are documented barriers to maintaining this nutritional strategy over time. Therefore, this study proposes that combining TRE with a psychochrononutritional program (integrating psychological, chronobiological, and nutritional components) will improve adherence to the nutritional strategy and lead to better health outcomes than only prescribing a specific eating window. To this end, 64 adults (18-60 years old) with metabolic syndrome will be recruited in Ciudad Guzmán, Jalisco, Mexico. The TRE intervention will last eight weeks and include two groups. One group will undergo a psychochrononutritional intervention, whereas the other will receive only instructions regarding the eating window. Within each group, two subgroups will be formed: one assigned to an 8-hour eating window, and the other to a 10-hour window. Before and after the intervention, anthropometric, biochemical (lipid profile and plasma glucose), clinical (blood pressure), and dietary assessments will be performed. We expect reductions in blood pressure, glucose, triglycerides, and waist circumference as well as better adherence in the psychochrononutritional intervention group.

The objective of this clinical trial is to determine whether α-tocopherol (vitamin E) supplementation decreases inflammation and clinical activity in patients with rheumatoid arthritis (RA).The main questions to be answered are: * Is supplementation with vitamin E (α-tocopherol) for one month associated with decreased clinical activity and inflammation in patients with RA? Researchers will compare α-tocopherol with a placebo (a look-alike substance containing no active ingredient) to see if α-tocopherol effectively reduces inflammation and clinical activity in patients with rheumatoid arthritis. Participants will: * Take two capsules (one in the morning and one in the afternoon) of either α-tocopherol or placebo every day for a month. * Attend clinic visits at the start of the intervention (baseline) and at the end of the month for final check-ups and tests. * Keep a diary to record your symptoms and how often you take α-tocopherol or placebo.

Fenugreek has been shown to have beneficial effects on various metabolic abnormalities associated with metabolic syndrome (MS). However, no clinical trials have evaluated its effect on all components of MS, insulin sensitivity, and insulin secretion. Therefore, the main objective of this study is to assess the effect of fenugreek seed administration versus placebo on the components of metabolic syndrome, insulin sensitivity, and insulin secretion.

Background: Abdominal obesity (AO) is a multifactorial disease that affects 81.6% of the Mexican population; it is characterized by the excessive accumulation of adipose tissue in abdominal region. Scientific evidence suggest that regional fat distribution plays a critical role in the development of cardiovascular diseases (CVD). The main processes involved in the increased risk of developing CVD in the presence of AO are alterations in insulin signaling, dyslipidemias, atherosclerosis, inflammation, and oxidative damage. On the last years has been reported genetic variations associated with AO and dyslipidemia. In addition, interactions have been found between these genetic variants and diet that may be influencing a differential response in metabolic, molecular, and phenotypic processes, which favor the development of CVD. Objective: Evaluate the effect of nutrigenetic intervention on cardiovascular biomarkers, oxidative stress and antioxidant capacity in subjects with abdominal obesity. Materials and methods: The present study is a simple randomized clinical trial. Participants will be randomized into one of two groups of intervention; Control group and Nutrigenetic group during a 2-month follow-up period. Anthropometric, dietary evaluation and biochemical markers assessments will be monitored at baseline, at 4 weeks (mid-intervention), and at 8 weeks (end of intervention). The dietary evaluation was analyzed by Nutritionist Pro software. Body composition was evaluated by electrical bioimpedance (InBody 370). All biochemical determinations were analyzed by dry chemistry (Vitros 350) and cardiometabolic markers by colorimetric immunoassay technology. Infrastructure: Institute of Translational Nutrigenomics and Nutrigenomics, University Center for Health Sciences, University of Guadalajara.

The goal of this clinical trial is to learn if curcumin can lower the inflammation in participants with chronic kidney disease (CKD) undergoing hemodialysis (HD). The main questions it aims to answer are: Does curcumin lower can lower profinflamatory markers in participants with CKD on HD? Researchers will compare curcumin to a placebo (a look-alike substance that contains no drug) to see if curcumin works to help the treatment in participants with CKD on HD. Researchers will compare nutritional status and side effects after taking the supplement. Participants will: Take the curcumin or a placebo twice a day for 3 months Visit the clinic once every week for checkups and tests.

The Metabolic Syndrome (MS) is a cluster of cardiometabolic risk factors, which include abdominal obesity, hyperglycemia, dyslipidemia, and high blood pressure. MS is a global health problem, it represents a risk factor for the progression of cardiovascular disease, which constitute the main cause of mortality in the world and in Mexico. The current treatment involves lifestyle changes and pharmacological treatment for each of the components of MS, however, there is no single approved treatment to control all components. Celery seed (Apium graveolens L.) from the Apiaceae family contains the flavonoids apigenin and luteolin; essential oils such as d-limonene, selinene and phthalides such as 3-n-butylphthalide. Thanks to its bioactive components, celery seed has proven to be effective in treating individual MS disorders; however, most studies are in animal models and there are no clinical studies that evaluate its effectiveness on all components of the system. MS, insulin sensitivity and insulin secretion so it could appear as a new, safe and effective complementary therapy for the treatment of MS. The aim of this study is to evaluate the effect of celery seed on the components of metabolic syndrome, insulin sensitivity, and insulin secretion.

Assess the effect of a casein-free and gluten-free diet on gastrointestinal symptoms, clinical variables, and the composition of the intestinal microbiota in Mexican children with autism spectrum disorder.

Vegetables, mainly green leafy ones and some others like beets, are a rich source of nitrate. Nitrate metabolism has shown benefits to the body and there are recent studies that agree that the consumption of nitrates from vegetables can modify the oral microbiota by increasing species with nitrate-reducing capacity, which are also bacteria that are associated with oral health.
