Filter by:Introduction: Fibromyalgia (FM) is a syndrome characterized by generalized musculoskeletal pain, fatigue, non-repairing sleep, cognitive changes, depressive symptoms and other correlates of autonomic dysfunction. A high prevalence of overweight in patients with fibromyalgia is observed, about 80% according to current data, which affects the course and prognosis of the disease, besides overburdening health costs and further compromising quality of life. life of these patients. Evidence shows possible pathophysiological pathways shared by these two pathologies, as well as aspects related to food behavior. It is known that dopaminergic neurotransmission is altered in both, suggesting an increase in the sensitivity or density of D2 dopamine receptors. Non-pharmacological options for pain management and dysfunctional eating behavior include the important contribution of neuromodulatory techniques of non-invasive cerebral stimulation, such as transcranial direct current stimulation (tDCS), which aims to increase resisting hyperpalatable foods and reducing caloric intake. Objectives: To evaluate the association between dopamine receptor-2 (DRD2) Taq1A allele A1 polymorphism (rs1800497) and to observe the possible effect of tDCS on the dorsolateral prefrontal cortex (DLPFC) on homeostatic and hedonistic aspects of eating behavior in women with FM. Methods: A randomized, double blind, parallel group, controlled trial with simulated treatment will be performed. Will be included in the study women literate, right-handed, with confirmed diagnosis of FM. The evaluation will be done through questionnaires on pain and eating behavior, anthropometric evaluation and biochemical measurements. The intervention will take place through active or simulated home for 4 weeks. Perspectives: To evaluate dysfunctional neuroplastic changes in eating behavior and biological markers and also to serve as a basis for future effective treatment strategies through neuromodulation and nutritional counseling.
Food addiction (FA) is a behavioral addiction characterized by a high consumption of palatable foods, which markedly activate the reward system, despite adverse consequences. FA was first described in 1956 but remains controversial. The Yale Food Addiction Scale (YFAS), developed by Gearhardt et al. in 2009, is currently regarded as the "Gold Standard" for FA screening. In a previous study, we established a Food Addiction Screening Test using artificial intelligence. The main objective of the present study is to validate the sensitivity, specificity and precision for FA diagnosis in a sample of patient suffering from obesity and healthy volunteers.
The current study experimentally investigates whether reducing highly processed (HP) foods (defined in this study as foods high in added sugars) leads to, psychological and / or behavioral indicators of withdrawal. The following hypotheses are tested: 1. To test the hypothesis that reducing highly processed food intake will result in higher daily reports of physical (e.g. headaches), cognitive (e.g. difficulty concentrating), and affective (e.g., irritability) withdrawal symptoms). 2. To test the hypothesis that reducing highly processed food intake will result in increased negative affect (e.g., irritability, depression) as indicated by and psychological (self - reported distress ratings; daily emotion / mood reports) measures. 3. To test the hypothesis that reducing highly processed food intake will result in increased food craving as indicated by psychological (self - report craving ratings; daily craving report) measures. All activities are completed remotely. Participants complete 4 phone appointments with a trained member of the research team. Daily questionnaires and ecological momentary assessments are completed at home between phone appointments. The initial call signs electronic consent and gets baseline measurements (questionnaires). After the initial call, participants start an active assessment period (pre / post dietary change assessments). Pre-dietary change includes at home questionnaires and ecological momentary assessments while eating a typical diet. It also includes the second phone appointment. Post-dietary change includes at home questionnaires and ecological momentary assessments while consuming 3 days of food portions lower in highly processed foods. Participants will complete a food journal on the remaining 2 days of post - dietary change assessment to report what food they ate. Post - dietary change also includes the third phone appointment. The second and third phone appointments each include computer tasks and questionnaires. The final phone appointment is a debriefing interview. Participants planning to continue eating a healthier diet may also be invited to complete a follow-up period, which involves answering a short questionnaire at home every other day for two weeks. 7 individuals had in-person data collected prior to the pandemic requiring a shift to virtual data collection.
Identification of the cerebral fMRI phenotype of obese patients with FA in cognitive task context based on food choice making
Research purpose: The purpose of this pilot study is to assess obese clients for two phenotypes, those testing positive and those testing negative for Food Addiction (FA) (Yale Food Addiction Scale, YFAS) and determining the efficacy of four treatments: usual care (IC, dietary and physical activity instruction), individual motivational interviewing alone (MI), individual MI with pharmacotherapy (MI+P) for improving outcome measures within each phenotype, and pharmacological therapy (P). Background/significance: Obesity has long been an epidemic in the U.S. and other countries. Numerous approaches have been tried to address obesity with limited success. The YFAS is a relatively new, validated instrument that can help researchers and practitioners assess obese clients for food addiction. Meeting the YFAS diagnosis criteria for FA suggests the need for a stronger intervention with close monitoring to assist these clients in self-management of their eating and physical activity behaviors. Proposed methods/approach: The investigators propose assessing obese clients with the YFAS as part of their intake once they are referred to the Healthy Behaviors Clinic by Regional West physicians/practitioners. A nurse researcher with expertise in MI and a nurse practitioner will perform intake assessments, obtain consent and randomly assign participants in each phenotype (positive or negative for FA) to one of three treatment groups (usual care, individual MI alone, and individual MI with pharmacotherapy). Interventions will occur over 6 months. A clinical psychologist with expertise in the YFAS (University of Michigan) will serve as a consultant on this project and a registered dietitian (University of NebraskaLincoln) will serve as a co-investigator. Expected outcomes: The investigators expect that MI and MI+P and P will be more effective in improving outcome measures than IC. We also expect that response to the treatments will differ between the two obesity phenotypes (those testing positive and those testing negative for FA).
Obesity is worldwide a public health problem. According to World Health Organization (WHO), overweight and obesity are the fifth death risk factor worldwide. At least 2.8 million adults die each year. Food addiction is one of the causes of obesity that may benefit from new therapeutic options.
The investigators will develop a measure of endogenous opioid tone that might serve as a biological marker for drive for palatable food. Using a 'naltrexone probe,' the investigators will assess whether individual response to one dose of an opioid receptor antagonist, naltrexone, is related to non-homeostatic eating in non-pregnant women. Hypothesis 1: Naltrexone Response will be related to non-homeostatic eating. Hypothesis 2: Response profiles to the 25 mg dose will be slightly less in magnitude than the 50 mg dose. However, responses will be similarly related to non-homeostatic eating measures. Hypothesis 3: Response to naltrexone will be highly stable within individuals across time, in the absence of an intervention.
