La violencia en el noviazgo que se ejerce a través de los medios tecnológicos y redes sociales (online) ha mostrado tener una alta frecuencia en la población de jóvenes y adolescentes. Se trata de un fenómeno relativamente nuevo cuya existencia ha sido catalogada como una extensión de la violencia ejercida cara a cara u offline. Pese a esto, son pocas las investigaciones encaminados en estudiar la relación entre ambos fenómenos. Por ello, el presente estudio tuvo como objetivo analizar la prevalencia y asociación entre la violencia offline y online en el noviazgo. Participaron 443 adolescentes (231 mujeres y 212 varones), quienes respondieron el Conflict in Adolescent Dating Relationship Inventory y el Cyber Dating Abuse Questionaire. Los resultados muestran la naturaleza bidireccional de las conductas violentas offline y online, lo que podría indicar su normalización. Entre otros datos, se resalta que la mayor perpetración de violencia emocional y física es ejercida por las mujeres, lo que iría en contravía de los perfiles convencionales de mujeres víctimas y hombres victimarios. No obstante, es preciso señalar que la violencia sexual fue mayormente ejercida por varones, lo cual es congruente con lo hallado en diversos estudios. Por último, se halló una asociación positiva entre la perpetración de la violencia offline y online en el noviazgo, lo que comprueba que las conductas violentas que se ejercen cara a cara se podrían trasladar a los medios tecnológicos y redes sociales.

Among neurodevelopmental disorders, attention deficit hyperactivity disorder (ADHD) is the main cause of school failure in children. Notably, visuospatial dysfunction has also been emphasized as a leading cause of low cognitive performance in children with ADHD. Consequently, the present study aimed to identify ADHD-related changes in electroencephalography (EEG) characteristics, associated with visual object processing in school-aged children. We performed Multichannel EEG recordings in 16-year-old children undergoing Navon’s visual object processing paradigm. We mapped global coherence during the processing of local and global visual stimuli that were consistent, inconsistent, or neutral. We found that Children with ADHD showed significant differences in global weighted coherence during the processing of local and global inconsistent visual stimuli and longer response times in comparison to the control group. Delta and theta EEG bands highlighted important features for classification in both groups. Thus, we advocate EEG coherence and low-frequency EEG spectral power as prospective markers of visual processing deficit in ADHD. Our results have implications for the development of diagnostic interventions in ADHD and provide a deeper understanding of the factors leading to low performance in school-aged children.

Migraine is a common, headache disorder characterized by recurrent episodes of headache often associated with nausea, vomiting, photophobia, and phonophobia. Prior to puberty, boys and girls are equally affected. Female preponderance emerges after puberty. Migraine pathophysiology is not fully understood, and although the hormonal effect of estrogen is significant, it is not clear how hormonal phases affect brain excitability and EEG patterns in women with migraine. The objective of this research was to study the effect of migraine on the resting-state EEG activity of women during the luteal phase. This work compares electroencephalographic (EEG) absolute power in different frequency bands and scalp areas between young women who suffer from migraine and had a migraine attack within 24 h prior to EEG recording (experimental) and ten age-matched young healthy women (controls), all with normal menstrual cycles. For women with migraine, we found a significant decrease/increase in alpha power in the occipitoparietal/frontocentral area, significant decrease in beta power for all areas, significant decrease in delta power in the temporal area, and significant decrease in theta power in the frontocentral and occipitoparietal area. We concluded that women with migraine have a distinct electroencephalographic pattern during the luteal phase in comparison with control women. A possible explanation might be an intermittent rhythmic activity linked to pain.

Traumatic brain injury (TBI), resulting from external forces, is a leading cause of disability and death, often leading to cognitive deficits that affect attention, concentration, speech and language, learning and memory, reasoning, planning, and problem-solving. Given the diverse mechanisms underlying TBI symptoms, it is essential to characterize its neurophysiological and neuropsychological effects. To address this, we employed weighted coherence (WC) analysis in patients performing the Halstead–Reitan categorization task, alongside a control group of eight healthy individuals. Our findings indicate a significant decrease in WC within the theta and delta bands in the temporal regions during cognitive tasks in the TBI group compared to controls. Additionally, we observed a significant increase in WC in the beta and gamma bands in the parietal region during both rest and cognitive tasks in the TBI group, relative to the control group. Furthermore, there was a strong correlation between WC and task performance scores in the temporal regions.

Objetivo: el síndrome de burnout es una condición surgida a partir de la demanda excesiva de energía, recursos y disponibilidad de los trabajadores, repercute en la integridad de quienes lo padecen. El objetivo de este estudio exploratorio, pionero, fue analizar el grado de síndrome burnout, malestar psicológico y satisfacción con la vida en una muestra de oficiales de policía mexicanos durante la pandemia de COVID-19. Materiales y métodos: se realizó un estudio no experimental, transversal, con alcances exploratorios, descriptivos y correlacionales con 27 policías del estado de Puebla [México], entre los 19 y 43 años de edad. Se utilizaron las escalas Maslach Burnout Inventory-Human Services Survey, Kessler’s Psychological Distress Scale y la Escala de Satisfacción con la Vida. Resultados: resalta una prevalencia alta de despersonalización en el 81,5% de la muestra; realización personal baja, en un 55,6%; y un agotamiento emocional alto, en el 37%. El 63% indicó malestar psicológico moderado y el 51,9%, una alta satisfacción con la vida. De igual forma, se identificaron asociaciones parciales entre las variables incluidas. Conclusiones: conviene adelantar nuevas investigaciones orientadas a detectar y promover factores protectores, mecanismos de defensa y tratamientos correspondientes para disminuir los índices del síndrome de quemarse en el trabajo en el sector policial.

O trabalho aborda a formação do papel mediador da linguagem em um grupo de crianças pré-escolares (GP1) e comparados com um grupo controle (GP2). No treinamento GP1 da metodologia de análise e interpretação atividades que foram implementadas conto. Os resultados mostraram diferenças significativas entre os grupos. Em GP1 maior coerência gramatical, intenção comunicativa foi observado e diálogos implantados emergiu. Conclui-se que o método é útil para implantação em grupos de crianças pré-escolares , nos casos em que é necessário melhorar o nível de preparação para a escola e o papel mediador da linguagem.
