Background: Disorders of gut–brain interaction (DGBI) are multifactorial. Early-life events are proposed as factors involved in their etiopathogenesis. The relationship between mode of delivery, prematurity, and DGBI development remains unclear. This study examines whether cesarean delivery and prematurity contribute to early childhood DGBI. Methods: Caregivers of children aged 1 month to 4 years from four Colombian cities participated in a cross-sectional study. Pediatricians completed the Spanish-validated Questionnaire of Pediatric Gastrointestinal Symptoms Rome IV (QPGS-IV). Data of children born by cesarean delivery and prematurity were compared with controls. Categorical data were analyzed using Fisher’s exact test, and odds ratios (ORs) with 95% confidence intervals (CIs). Results: DGBIs were identified in 26.6% of children, with functional constipation (FC) being the most pre...

Recent studies report a high prevalence of psychotic and substance use disorders sharing common brain mechanisms that may affect cognitive performance, response to treatment, the ability to commit to it and, consequently, increase the risk of relapse. Objective: To compare cognitive performance in patients with alcoholism and schizophrenia. Material and Methods: Observational study designed to evaluated 18 patients with schizophrenia and 32 with mental disorders due to alcohol consumption. The short neuropsychological battery NEUROPSI, validated in Spanish, was the main study instrument. Results: Significant differences were found between both groups in areas of executive function and long-term memory, with the sub-group of patients with schizophrenia showing greater deterioration levels. Conclusion: The results assist in explaining and understanding the difficulties that patients with s...

The development of Internet of Things (IoT) applications for creating behavioural and physiological monitoring methods, such as an IoT-based student healthcare monitoring system, has been accelerated by advances in sensor technology. Today, there are an increasing number of students living alone whoare dispersed across large geographic areas, therefore it is important to monitor their health and function. This research propose novel technique in high performance modelling for health monitoring system by 5G network based machine learning analysis. Here the input is collected as EEG brain waves which are monitored and collected through 5G networks. This input EEG waves has been processed and obtained as fragments and noise removal is carried out. The processed EEG wave fragments has been extracted using K-adaptive reinforcement learning. this extracted features has been classified using na...

The purpose of this paper is to provide a theoretical approach to the notion of political counter-narrative. Given the novelty of this narrative technique, its causes are first addressed: moral absolutism, affective polarization, informational chaos, uncertainty, and digital tribalism. Then, the counter-narrative is defined as a semantic structure that, regardless of temporality, seeks to destroy the symbolic capital of the adversary. Subsequently, its main features –reactivity, negativity, emotiveness, stereotyping, and permanence– are detailed, as are its functions –linking wills through opposition, drawing clear identity boundaries, being emotionally rewarding, and simplifying reality–. In closing, a review of the main findings is provided, and various lines of research are proposed, such as observing the resonance and application of this technique by citizens and the possibil...

Autism Spectrum Disorder (ASD) is considered a neurodevelopmental disorder, whose prevalence has increased in recent years, showing in some cases deficits in the cognitive area, with processing speed (PS) being one of the affected variables. Therefore, the present study aims to: 1) compare the scores obtained in relation to the PS variable between students aged 6 to 11 with ASD and their peers with neurotypical development in Metropolitan Lima; and 2) establish the PS profile of the included students with ASD. For this, 30 children aged 6 to 11 attending to regular basic education institutions (RBE) in Metropolitan Lima were sampled, 15 with neurotypical development and 15 included with ASD. For the first objective, a case-control design (CCD) was used, while the second objective was a selective non-probabilistic cross-sectional design. Results showed a lower performance by the group wit...

Los primeros años de vida el cerebro es más flexible o “plástico” y contempla períodos sensibles o críticos, donde una amplia gama de entornos e interacciones influyen sobre este. La adolescencia también es un periodo sensible, pues se reorganiza la estructura cerebral y se da una maduración cognitiva y cerebral. Si la deficiencia de un nutriente ocurre en el periodo de tiempo cuando este es necesario para el desarrollo neurológico, puede que el desarrollo del cerebro sea alterado, los niños que no están adecuadamente alimentados corren el riesgo de no alcanzar su potencial de desarrollo en las habilidades cognitivas, motoras y socioemocionales. Para la ejecución de este estudio se utilizaron datos de un estudio aleatorizado doble longitudinal realizado en Instituto de Investigación Nutricional (IIN) en el cual un grupo de adolescentes de 14 años que recibieron un suplem...

INTRODUCCIÓN: El embarazo constituye una de las etapas de mayor vulnerabilidad nutricional y tiene un efecto determinante en el crecimiento fetal y su peso. Según la Organización Mundial de la Salud (OMS), el bajo peso al nacer es ‹ 2,500 g y es el índice predictivo más importante de mortalidad infantil, y la anemia en el embarazo es ‹11g/dl, y se asocia fundamentalmente con factores relacionados a la deficiencia de hierro, con pobres condiciones de vida y hábitos nutricionales deficientes. El estado del hierro del feto y del recién nacido dependen de la condición del hierro en la madre gestante; y, en consecuencia, su deficiencia en la futura madre significa que el feto en crecimiento también puede presentarla; pues éste mineral es esencial para el desarrollo y crecimiento normales de la mayoría de los órganos en el feto, especialmente de los órganos hematopoyéticos; y...

Neural self-organization is an innate feature of the brains of mammals and it isvery necessary for their operation. The most known artificial neural network models that use this characteristic are the Self-Organized Maps (SOM) and the Adaptive Resonance Theory (ART), but these models do not take the neuron as a processing unit, as it’s biological counterpart does; besides these are models mostlyused for the unsupervised learning paradigm, this means that there aren’t robustself-organized models in the supervised learning paradigm. In other way, influence value reinforcement learning paradigm, used in multi-agent systems, prove thatagents can communicate among them, and can self-organize themselves to assigntasks, without interference.Motivated by the lack of features in the artificial neural networks, and taking intoaccount the influence values reinforcement algorithm, a new neural n...
