Cross-cultural adaptation and validation of the cooking task to the French-Canadian context: assessing the impact of executive function disorders through cooking activities.

Background: Acquired brain injury (ABI) often leads to deficits in executive functioning (EF) which is responsible for severe and longstanding disabilities in activities of daily living. The "Cooking Task" (CT), an ecological test of EF involving multi-tasking, was developed in France and exhibits excellent psychometric properties but has not yet been adapted and validated for the French-Canadian context.

Objectives: Conduct a cross-cultural adaptation and validation of the CT for the French-Canadian context.

Comparison of the efficiency of chopped and non-rectangular electrical stimulus waveforms in activating small vagus nerve fibers.

Background: In the context of morbid obesity, vagus nerve stimulation could be used to control gastric function targeting the small afferent B-fibers and C-fibers. Compared to large A-fibers, activation thresholds of these small efferent fibers are 10 to 100 times greater, inducing technical constraints and possible nerve damages. Although rectangular waveform is commonly used in nerve stimulation, recent modeling and experimental studies suggest that non-rectangular waveforms could reduced the charge injected by the stimulator.

Adequacy of Some Locally Produced Complementary Foods Marketed in Benin, Burkina Faso, Ghana, and Senegal.

Adequate complementary foods are needed to help reduce the high prevalence of stunting in children in many Low and Middle Income Countries (LMICs). We assessed the availability, affordability, and nutrient adequacy of imported and locally produced processed cereal-based blends (PCBBs), marketed as complementary food for young children in Benin, Burkina Faso, Ghana, and Senegal. In total, 19 local producers and 275 points of sale in the four countries were surveyed to evaluate the quantities and accessibility of PCBBs.

Effects of cooking and food matrix on estimated mineral bioavailability in Mloukhiya, a Mediterranean dish based on jute leaves and meat.

Traditional Mediterranean plant-based dishes could allow tackling malnutrition while preserving the cultural heritage. To determine the effect of the cooking method on mineral bioavailability, the content in minerals and chelators of Mloukhiya, a Mediterranean dish based on jute leaves (Corchorus olitorius) that contains also meat, was monitored during the whole cooking process. Mineral bioaccessibility was assessed by measuring in vitro dialyzability.

Effects of chronic abdominal vagal stimulation of small-diameter neurons on brain metabolism and food intake.

Background: Abdominal bilateral vagal stimulation reduces food intake in animals. However, the classical square wave, mA range current generator is poorly effective to evoke action potentials on A∂ and C neurons that represent the majority of vagal neurons at the abdominal level.

Objective/hypothesis: METHODS: The current thresholds for pulsons (S2 & S3) and millisecond pulses (S1) required to trigger action potentials were calculated in 5 anaesthetized pigs using single fibre recording.

Effectiveness of a multidisciplinary rehabilitation program for persons with acquired brain injury and executive dysfunction.

Purpose: The purpose of this study is to explore the effects of a multidisciplinary acquired brain injury rehabilitation out-patient program (5 d/week for 7 weeks) on improvements to participants' activity and participation outcomes related to meal preparation and to determine whether gains are maintained at 3 and 6 months post program.

Methods: A single case experimental design with repeated measures pre- and post-intervention with 7 adult participants with ABI and executive dysfunction (4 females, mean age 38 ± 10.1 years) was used.

Obesity-Associated Alterations in Glucose Metabolism Are Reversed by Chronic Bilateral Stimulation of the Abdominal Vagus Nerve.

Acute vagal stimulation modifies glucose and insulin metabolism, but the effect of chronic bilateral vagal stimulation is not known. Our aim was to quantify the changes in whole-body and organ-specific insulin sensitivities 12 weeks after permanent, bilateral, vagal stimulation performed at the abdominal level in adult mini-pigs. In 15 adult mini-pigs, stimulating electrodes were placed around the dorsal and ventral vagi using laparoscopy and connected to a dual-channel stimulator placed subcutaneously.

Exploring Selective Neural Electrical Stimulation for Upper Limb Function Restoration.

This article introduces a new approach of selective neural electrical stimulation of the upper limb nerves. Median and radial nerves of individuals with tetraplegia are stimulated via a multipolar cuff electrode to elicit movements of wrist and hand in acute conditions during a surgical intervention. Various configurations corresponding to various combinations of a 12-poles cuff electrode contacts are tested.

Vagus nerve stimulation: state of the art of stimulation and recording strategies to address autonomic function neuromodulation.

Objective: Neural signals along the vagus nerve (VN) drive many somatic and autonomic functions. The clinical interest of VN stimulation (VNS) is thus potentially huge and has already been demonstrated in epilepsy. However, side effects are often elicited, in addition to the targeted neuromodulation.

Chronic vagus nerve stimulation in Crohn's disease: a 6-month follow-up pilot study.

The vagus nerve (VN) is a link between the brain and the gut. The VN is a mixed nerve with anti-inflammatory properties through the activation of the hypothalamic-pituitary-adrenal axis by its afferents and by activating the cholinergic anti-inflammatory pathway through its efferents. We have previously shown that VN stimulation (VNS) improves colitis in rats and that the vagal tone is blunted in Crohn's disease (CD) patients.

Determining Factors of Lipophilic Micronutrient Bioaccessibility in Several Leafy Vegetables.

Micronutrient deficiencies are still a public health issue in least developed countries. Promoting diet diversification is a promising strategy. Numerous fruits and vegetables are rich in micronutrients, but some of these compounds are poorly bioaccessible.

The type of fortificant and the leaf matrix both influence iron and zinc bioaccessibility in iron-fortified green leafy vegetable sauces from Burkina Faso.

Leafy vegetable sauces from Burkina Faso were assessed as a potential vehicle for food fortification. First, iron and zinc bioaccessibility were measured by dialysability method in amaranth and Jew's mallow sauces and in traditional whole dishes consisting of maize paste plus leafy vegetable sauces. Iron dialysability and solubility were higher in amaranth than in Jew's mallow sauce, pointing to a marked effect of the matrix.

Contribution of leafy vegetable sauces to dietary iron, zinc, vitamin A and energy requirements in children and their mothers in Burkina Faso.

Improved leafy vegetable (LV) sauces, with amaranth, sorrel, and Ceylon spinach/spider plant leaves were formulated from traditional recipes to assess their potential use for food-to-food fortification in iron, zinc and vitamin A in the diet of young children and their mothers in Burkina Faso. Improvement was based on an increase in LV proportion and a decrease in mineral absorption inhibitors. An increase in iron content of up to 3 mg/100 g was obtained in some improved sauces in which dried fish was replaced by chicken liver, and vitamin A content was about 40 times higher than in traditional sauces.

Determination of expression and activity of genes involved in starch metabolism in Lactobacillus plantarum A6 during fermentation of a cereal-based gruel.

Traditional fermented gruels prepared from cereals are widely used for complementary feeding of young children in Africa and usually have a low energy density. The amylase activity of some lactic acid bacteria (LAB) helps increase the energy content of gruels through partial hydrolysis of starch, thus enabling the incorporation of more starchy material while conserving the desired semi-liquid consistency for young children. Even if this ability is mainly related to the production of alpha-amylase (E.

Effects of water soaking and/or sodium polystyrene sulfonate addition on potassium content of foods.

In this study, we determined, by atomic absorption spectrophotometry, the potassium amount leached by soaking or boiling foods identified by children suffering from chronic renal failure as "pleasure food" and that they cannot eat because of their low-potassium diet, and evaluated whether addition of sodium polystyrene sulfonate resin (i.e. Kayexalate®) during soaking or boiling modulated potassium loss.

Rapid quantification of iron content in fish sauce and soy sauce: a promising tool for monitoring fortification programs.

Background: In a number of Southeast Asian countries and China, fish sauce and soy sauce produced at the industrial level are fortified with iron. Unfortunately, the food producers and regulatory agencies implementing fortification programs do not always have the capacity to monitor the programs on an ongoing basis.

Objective: To assess a new portable device for the quantitative measurement of iron content of fortified sauces that could be used to control fortification levels.

Impact of Anesthetics on Immune Functions in a Rat Model of Vagus Nerve Stimulation.

Vagus nerve stimulation (VNS) has been successfully performed in animals for the treatment of different experimental models of inflammation. The anti-inflammatory effect of VNS involves the release of acetylcholine by vagus nerve efferent fibers inhibiting pro-inflammatory cytokines (e.g.

Vagus nerve stimulation: from epilepsy to the cholinergic anti-inflammatory pathway.

Background: The brain and the gut communicate bidirectionally through the autonomic nervous system (ANS). The vagus nerve (VN), a major component of the ANS, plays a key role in the neuro-endocrine-immune axis to maintain homeostasia through its afferents (through the activation of the hypothalamic pituitary adrenal axis and the central ANS) and through its efferents (i.e.

Fermentation by amylolytic lactic acid bacteria and consequences for starch digestibility of plantain, breadfruit, and sweet potato flours.

Unlabelled: The potential of tropical starchy plants such as plantain (Musa paradisiaca), breadfruit (Artocarpus communis), and sweet potato (Ipomoea batatas) for the development of new fermented foods was investigated by exploiting the capacity of some lactic acid bacteria to hydrolyze starch. The amylolytic lactic acid bacteria (ALAB) Lactobacillus plantarum A6 and Lactobacillus fermentum Ogi E1 were able to change the consistency of thick sticky gelatinized slurries of these starchy fruits and tubers into semiliquid to liquid products. Consequently, a decrease in apparent viscosity and an increase in Bostwick flow were observed.

Anti-inflammatory effect of vagus nerve stimulation in a rat model of inflammatory bowel disease.

Vagus nerve stimulation of afferents is used as an adjunctive treatment for drug-resistant epilepsy and depression. In addition, anti-inflammatory properties of vagus nerve stimulation have been reported in various experimental models of inflammation but not in colitis. These effects are thought to be mediated via peripheral release of acetylcholine from the vagus and subsequent activation of macrophages.

Dynamic Causal Modelling and physiological confounds: a functional MRI study of vagus nerve stimulation.

Dynamic Causal Modelling (DCM) has been proposed to estimate neuronal connectivity from functional magnetic resonance imaging (fMRI) using a biophysical model that links synaptic activity to hemodynamic processes. However, it is well known that fMRI is sensitive not only to neuronal activity, but also to many other psychophysiological responses which may be task-related, such as changes in cardio-respiratory activity. They are not explicitly taken into account in the generative models of DCM and their effects on estimated neuronal connectivity are not known.
