Effectiveness of the implementation of a parental tele training program on passive vocabulary in children with Specific Language Disorder: A review of the literature
Specific Language Impairment limits the communication and participation of children diagnosed with it. Its symptomatology is diverse and includes limitations in oral comprehension and production, as well as reduced passive vocabulary. Passive vocabulary is a key factor in language comprehension and is linked to successful communication, highlighting the importance of analyzing the literature on intervention programs with an emphasis on this skill from early stages, considering the contexts in which children live and interact. Several intervention programs target the families of children with Specific Language Impairment. Therefore, the purpose of this narrative review is to compare the effectiveness of these programs, assessing fidelity, materials used, implementation duration, post-treatment follow-up, and other criteria. It also aims to analyze the different skills targeted for intervention in each program and how vocabulary development is addressed. An advanced search was conducted in databases (PubMed, ASHA, Cochrane, and Google Scholar), selecting five articles from the period 2019–2024. Various programs, their implementation methods, and target populations were analyzed, considering treatment frequency and duration, fidelity in implementation, the recipient of the intervention, and how these variables influenced children's language, communication, and vocabulary. The results of the five analyzed programs demonstrate the effectiveness of treatment across different modes of intervention delivery. In conclusion, there is a lack of structured programs to train caregivers of children with Specific Language Impairment to create enriched home environments and foster both passive vocabulary and various linguistic and communicative abilities.

Metalinguistic Skills Intervention for Reading Learning in Spanish-Speaking Schools: A Systematic Review
Introduction: There is a close relationship between spoken and written language, as both share the same processing system; metalinguistic skills therefore become crucial in this process. Research highlights the importance of Phonological Awareness in reading, although there is less evidence regarding the involvement of other metalinguistic skills in reading comprehension in Spanish. Methods: A systematic search was carried out in the WOS, SCOPUS, ERIC, and EBSCO databases using key terms such as “Metalinguistic Skills,” “literacy development,” and “intervention,” along with their synonyms, covering the last five years. Results: After applying the inclusion and exclusion criteria, six studies were obtained and analyzed in line with the objective. Analysis and Discussion: Phonological Awareness is the metalinguistic skill most requently addressed for reading acquisition, and there is limited evidence of interventions targeting other metalinguistic skills in Spanish-speaking populations. Conclusions: Phonological interventions are effective; it is necessary to promote reading intervention programs that encompass all metalinguistic skills.

Perceptions regarding the use of ICT in the development of Reading skills of students with intellectual disabilities: A perspective from the teaching staff
Introduction: The use of Information and Communication Technologies (ICT) is an increasingly common resource in the classroom, used by teachers and therapists due to the high acceptance and interest it generates among students. In children with intellectual disabilities, it has proven to be an effective tool in literacy work. Objective: To explore the perceptions that primary school teachers have regarding the use of ICT in developing reading skills in students with intellectual deficits. Method: A qualitative study with a phenomenological approach was conducted, involving five primary school teachers. Data was collected through semi-structured interviews, which were recorded and later transcribed. The study received approval from the Ethics Committee of the University of the Social Argentine Museum. Results: The analysis revealed five categories: facilitators of learning; conditions for achievement; pedagogical reflection; pedagogical differentiation; inclusion and accessibility. All agree that the use of ICT generates greater interest and meaningful learning. They mention that although ICT are useful, it is important to receive training or guidance to ensure activities meet their objectives. Most noted that using ICT has made them reflect on their work, and they agree that it is a differentiating and inclusive resource for students with disabilities.Conclusion: Participants valued the use of ICTs as a motivating, differentiating, inclusive, and adaptable resource for students with disabilities, facilitating literacy learning.

Impact of Covid-19 Isolation on Language Development: A Children's Court in Cartagena, Colombia
COVID-19 is an infectious disease that led to the implementation of measures such as social isolation in numerous countries, including Colombia. This isolation, extended for approximately 12 months, generated environmental deprivation in developing children by limiting social experiences, games in the environment. This study aimed to assess the impact of Covid-19 isolation on the language development of children born during this period. The methodology focused on a cross-sectional correlational study in which the MacArthur-Bates Communicative Development Inventory was applied to parents and/or caregivers of children along with a structured sociodemographic interview. In the results of the research, a significant percentage showed poor expressive vocabulary, alteration in the production of sentences and impairments in the use of grammar, as expected for their age. Although there was no statistically significant difference between the crossed criteria, it can be stated that class differences, exposure to Cartagena popular culture of the majority of the sample and informal employment were aspects that influenced the study. Finally, it is concluded that isolation due to COVID-19 generated a series of implications in the language development of children born in this period.

Use of ICT in the development of phonological awareness in a student with mild intellectual disabilities
Phonological awareness is part of a set of linguistic and cognitive skills that serve as predictors of reading acquisition. Typically developing children acquire this skill approximately between the ages of 4 and 8. There is evidence indicating a lag in the performance of phonological awareness tasks in children diagnosed with intellectual disability. In recent years, the use of Information and Communication Technologies (ICT) has extended beyond recreational purposes to include therapeutic applications. This study aims to integrate new therapeutic methodologies to enhance the development of phonological awareness in a child with mild intellectual disability. The implementation of the ICT-based activity “task X from program X” proved effective in improving phonological awareness performance.

Neuropsychology and Language. Case Study
The language is fundamental for the development of human thought, acting as a means of expression and understanding of reality. This cognitive process requires the proper functioning of neuropsychological processes, such as attention, memory and intellectual abilities, as postulated by Alexander Luria. However, traumatic events, such as brain injuries, can compromise both language and other cognitive skills essential for daily life. This case study explores the neuropsychological processes in a 17-year-old patient with a history of traumatic brain injury, who presents with dysarthria and aphasia. Through clinical observation, it has been shown that language alterations are accompanied by deficits in various cognitive functions. This analysis is based on the theories of Luria and Alfredo Ardila, providing a guide to evaluate the interrelation between neuropsychological processes and language development from a speech therapy approach.

Cross-cultural adaptation for Chile of the EVALOF assessment scale for parents
Language is a cognitive function that is considered important for sharing and organizing our daily lives. At the same time, it is a fundamental pillar of human relationships; however, not all children develop language appropriately. In Chile, it is possible to observe a prevalence of specific language impairment among 3% to 10% of the child population, which directly impacts families and their communicative interactions with their children. For this reason, it is necessary to validate assessment scales for measuring communicative interactions between parents and children in a family context, in order to have more precise, valid, and reliable instruments. The objective of this study was to linguistically validate the Scale for the Assessment of Oral Language in Family Context (EVALOF) self-administered version. The methodology is quantitative, descriptive in scope, non-experimental, and cross-sectional, with 67 subjects participating. Among the results, it was observed that the suggestions proposed by the linguists were consistent when making adjustments to the instrument; similarly, the twelve expert judges expressed their observations and assessments indicating improvements and adjustments required for the instrument. Additionally, reliability estimates were achieved with a pilot study involving 53 parents, yielding a score of 0.84, considered as “good” reliability. It is concluded that the EVALOF instrument is valid and reliable in its transcultural adaptation for Chile, as it underwent tests that meet quality stand Ards and methodological rigor.

Frontal cerebral atrophy associated with neurodevelopmental delay in an infant with perinatal asphyxia: a clinical case report
Perinatal asphyxia is one of the main causes of neonatal hypoxic-ischemic encephalopathy, a condition that can lead to structural brain atrophy with significant repercussions on child neurodevelopment. We present the clinical case of a 15-month-old infant with a history of severe neonatal asphyxia, who presented with global developmental delay, microcephaly, and persistent irritability. Brain MRI showed severe bilateral frontal atrophy, ventriculomegaly, and chronic prefrontal subdural hematoma. An intensive, interdisciplinary therapeutic approach was implemented, with partial improvements in postural control and social interaction. This allowed us to illustrate the correlation between structural hypoxic damage and functional alterations, as well as the importance of early diagnosis and comprehensive intervention to improve functional prognosis.

Speech acts as indicators of communicative intention: literature review and analysis
Introduction: Human communication is a complex process that involves not only the transmission of information but also the expression of intentions and actions through speech acts. Developed by J.L. Austin and John Searle, speech acts play a key role in the creation of social relationships and the understanding of communicative intent. This review aims to explore how speech acts can be used as tools to measure communicative intent in clinical and educational contexts, with a particular focus on child development and the early identification of pragmatic difficulties. Materials and Methods: Following the PRISMA model, this review collected studies published between 2010 and 2024 that investigated the use of speech acts as a unit of measurement. The review included theoretical and empirical research focused on the pragmatics of language across various populations. Searches were conducted in databases such as PubMed and Google Scholar using key terms in both English and Spanish. A qualitative analysis identified patterns in the use of speech acts to assess communicative intent, their relationship with child language development, and their application in the diagnosis of disorders such as Autism Spectrum Disorder (ASD) and Developmental Language Disorder (DLD). Results: The reviewed studies revealed a consensus on the utility of speech acts as a key diagnostic tool, particularly in child development and the diagnosis of language disorders. The connection between speech acts and cognitive development was emphasized, as well as the importance of assessing communicative intent in natural contexts. However, some studies did not delve deeply into the practical application of speech acts in therapeutic interventions. Although their diagnostic value is recognized, the potential of speech acts as a foundation for treating pragmatic difficulties remains an area requiring further exploration.

The development of language is closely linked to the development of thought and follows a series of systematic and sequential stages or stages, which allow a certain degree of maturity and independence to be achieved. Sometimes there are difficulties that interfere with language development, one of the most frequent causes in infants is simple language delay. This manuscript seeks to systematize the clinical professional experience, with a 5-year-old male user, during which a question arose: What is the symbolism and abstraction of concepts like in a semantic deficit? To answer this question, it was necessary to use two lines of force such as Jean Piaget and Jerome Bruner, who focus on a psychocognitive approach. Thanks to the application of methods such as the E.L.C.E, token test, terman and merril and the bases of the lines of force, it was possible to obtain results that answered the question, determining that simple language delay affects the development of thought, causing The transition between sensorimotor and conceptual intelligence does not occur correctly, affecting the representation of symbolic thought and the abstraction of concepts. Which affects the user's proper development at a communicative level.

Performance in attention tasks of schoolchildren in primary education with and without oral breathing
Breathing influences craniofacial and systemic development. When it's through the mouth, it can affect cognitive performance during the school years. This study compared sustained attention performance in schoolchildren with and without mouth breathing during the second semester of 2023 in Temuco. The methodology involved an observational, cross-sectional, and comparative scope design, with non-probabilistic convenience sampling, excluding known respiratory or cognitive pathologies. 45 students between 7 and 9 years old participated. A speech therapy protocol and the D2-R test were used to evaluate breathing and attention, respectively. 17 participants had mouth breathing (38%). No significant differences were found in the D2-R test when grouped by performance (chi-square, p = 0.059). When comparing scores, there was significance overall and in the male group (t-test, p = 0.040 and p = 0.035, respectively). The results suggest potential attentional difficulties in schoolchildren with mouth breathing.

Evaluation of virtual learning environments in the formation of linguistic competences: a study in higher education
Introduction: The study analyzes the effectiveness of Virtual Learning Environments (VLEs) in the Bachelor's degree program in Spanish and English in blended mode in a higher education institution. The research is justified by the growing importance of VLEs in modern education. Methods: A descriptive cross-sectional design was used, collecting data through an online questionnaire applied to 31 students from different academic levels. The instrument evaluated organizational, pedagogical, accessibility, communication and didactic strategies aspects, as well as the development of English language skills. Results: The descriptive analysis showed that students perceive VPAs as effective tools for learning, highlighting the organization and pedagogical level, with positive evaluations in access to information and teacher-student interaction. The levels of accessibility and communication also received favorable evaluations. Analysis and Discussion: The need to strengthen technical support and training in virtual tools was identified. Didactic strategies, especially those focused on active and collaborative learning, were well valued; however, a limited use of advanced strategies such as concept mapping was evidenced. Despite general satisfaction with English reading and writing competencies, concerns were detected regarding the development of oral and listening skills, necessary to reach the C1 level required by national standards. Conclusions: These findings highlight the potential of the VPAs and key areas for improvement, such as curricular diversification, strengthening didactic strategies, and adjusting content to respond to academic and professional demands.

Impact of breastfeeding on orofacial growth and development: A systematic review
Introduction: Breastfeeding facilitates coordinated movements of the tongue, jaw, and lips, which are essential for proper sucking and organized orofacial development. This study examines the effects of breastfeeding on orofacial development and growth as documented in scientific literature. Methods: A systematic review was conducted using SciELO, PubMed, and the Cochrane Library with terms such as "Breastfeeding," "Growth & Development," and "Breastfeeding Behavior," covering studies from the past 10 years. Results: The reviewed studies indicate that breastfeeding is associated with childhood dentomaxillary growth and may reduce the incidence of malocclusions and oral habits. Discussion: A positive association is highlighted between exclusive breastfeeding and healthy orofacial development, while recognizing methodological limitations and variability in results. Conclusion: Direct breastfeeding plays a significant role in optimal growth of the cranio-cervico-mandibular complex (CCCM) and oral health, underscoring its impact on public health and the promotion of beneficial practices for children's orofacial development. The need for continued research is emphasized to inform clinical practices and public health policies related to breastfeeding and orofacial development.}

Verbal intelligence indices of students at a public educational institution in Cúcuta.
Verbal intelligence is the ability to use words effectively, either orally or in writing, allowing the expression of thoughts and emotions through a code between two or more people with a common theme. Research of quantitative nature and descriptive cross-sectional study level, developed during the second semester of 2022; using the verbal intelligence test higher level (INVE-S); 171 students of a public school in the city of San José de Cúcuta, department of Norte de Santander, were evaluated in the year 2022 in a period of time from September to November using the verbal intelligence test higher level INVE-S. The students in general did not reach an average level of verbal intelligence since they present notorious difficulties at the level of syntax, morphology, transitive reasoning, reading comprehension and other aspects at a general level, being these dimensions the most altered in the development of the test; it is important to establish that the methodologies of work and interaction have changed and that nowadays the great majority of young people are affected by technology. The indices obtained in the research establish that 10% of the general results reached a MEDIUM-LOW level and 90% a LOW level, in relation to the development of verbal intelligence.

Influence of bilingualism in children of Mapuche descent diagnosed with DLD
Language disorder is a condition that affects an individual’s ability to comprehend, express, or use language appropriately. That’s why it is of utmost importance to detect it early and initiate appropriate intervention to help improve communicative skills and reach their maximum potential, a task fulfilled by Language Schools in Chile. According to the National Institute of Statistics of Chile, people belonging to the mapuche culture amount to 1.745.147 individuals, constituting 10.2% of the Chilean population. Most of them reside in the Metropolitan region (31.8%), followed by the La Araucania region (14.7%) (1). Forty-four percent of the mapuche population has some degree of bilingualism due to their ability to speak their mother tongue, Mapudungun, with Spanish being the predominant language in Chile (2). This characteristic poses signiant challenges when subjecting mapuche children to language assessments conducted by professionals in the field. Therefore, this work aims to identify the (possible) existence of a significant difference between two groups of schoolchildren, one of them belonging to the mapuche culture.

To investigate whether bilingualism influences the diagnosis of Developmental Language Disorder (DLD). The particular case of bilingualism (Mapudungun/Spanish) in Chile
Bilingualism in mapuche children in chile is evident. In Chile there are one million people recogniced as mapuche and 60% of them speak mapudungun. Within this 60% there are children with language disorders who are part of chilean language schools (escuelas de lenguaje). Considering this situation, a set of questions related to the capacity of these schools to evaluate bilingual children and see if they are in desadvantage to monolongial children have arisen. This work focus on the relation between bilingualism and language disorders and the situation of schools in Chile. An exhaustive revision of the literature including miths on learning a second language and how language disorders in bilingual children affect was carried out. We emphasize the necessity of updated investigations about bilingualism and language disorders in mapuche children and the adaptation of schools to evaluate and intercede in mapuche children considering their cultural and linguistics characteristics

Telepractice: A new challenge for speech and language therapy in Latin America
Telepractice is defined by ASHA as "the provision of services through the use of telecommunications technology and the Internet to remotely connect clinicians with clients, other health care providers, and education professionals for screening, assessment, intervention, consultation, and education." Implementing this care modality is part of the digital health model proposed by the World Health Organization. With the advent of the COVID-19 pandemic, the need for these services increased exponentially in developing digital health, giving rise to new speech and language care challenges. The following review aims to deepen the knowledge of implementing telepractice as a care modality. A survey of scientific and bibliographic journals on the history of telepractice, national and international regulations, its clinical application, and its impact on higher education was carried out. This compilation shows that telepractice has served as a tool to provide health services, advancing at the pace of ICTs development. The implementation and adaptation to the different professional services, including speech and language therapy, improved access to care for more people. However, the COVID-19 pandemic showed that the regulations of the services, the use and access of ICTs, and the training of professionals for this type of care are still challenges to be improved.

Voice and speech disorders in Parkinson's disease: A review of the literature.
Parkinson's disease (PD) is a progressive neurodegenerative process whose lesion falls on the substantia nigra. Within the classic symptoms we can find motor symptoms such as tremor at rest, rigidity, bradykinesia, hypokinesia or akinesia, which affect all motor processes including phonation. The purpose of this study was to describe the vocal and speech disorders present in patients with PD from a review of the available literature on the problem. In conclusion, the existing literature shows that there are voice and speech parameters evident to perception characteristic of the disease, such as hypophonia, tremor, dysprosody, decreased speed, and articulatory inaccuracies. However, regarding the acoustic analysis of the voice, the results are still contradictory in some parameters, which could be attributed to differences in the methodology used. Although acoustic analysis is seen as a powerful diagnostic tool even in podromic stages of the disease, further research is required in this regard

Perception of vocal difficulties in people with Parkinson's disease: a perspective from the socio-family environment.
Introduction: Parkinson's disease (PD) is a complex neurodegenerative process that occurs in adulthood and can cause motor and non-motor symptoms. The voice of people with PD changes, which can affect their communication with their environment, as it also changes how others perceive their voice. Objective: To assess the perception of vocal difficulties in people with PD from the perspective of their social and family environment. Methodology: A cross-sectional, descriptive, observational study was conducted with the participation of 17 family members of members of the Association of People with Parkinson's Disease, family members, and friends from the city of Temuco (primary caregiver of the person with PD). Sampling was carried out using a face-to-face survey adapted from the VHI-30. Results: 71.2% of participants were over 40 years old, 76.5% were women, and they spent more than 5 hours a day with their family member with PD. 76.4% of participants perceived some impact of vocal difficulties on their family member with PD, considering functional, physical, and emotional criteria. Of these, 29.4% had mild to moderate difficulties, and 47% had severe to severe difficulties. Conclusion: Family members and/or caregivers may perceive vocal difficulties in people with PD to varying degrees. Involving the community and family during therapeutic support is essential for coping with the disease.

Relationship between self-perceived vocal disability and disease severity in patients with Parkinson's disease
Introduction: Parkinson's disease (PD) is a slowly progressing and highly debilitating neurological disorder of the central nervous system. Voice production requires the coordinated and precise action of intervening subsystems, which are affected by the motor symptoms of PD, with varying degrees of involvement depending on the stage of disease progression. Objective: To relate self-perceived vocal disability with the severity of the disease. Method: This was a cross-sectional observational study. The sample consisted of 27 patients with PD attending the Parkinson's Association of Temuco, Chile. Vocal disability was obtained using the VHI-30 questionnaire, and severity was determined using the Hoehn-Yahr scale. Results: A positive association was found between the Total VHI and the severity of the disease; however, this association was not significant. The same was true between the Total VHI and the years of disease progression. In turn, a positive and statistically significant correlation is evident between the years of onset and the severity of the disease. Conclusion: People with PD experience changes in their voice related to the disease and perceive these difficulties as increasing with the progression of PD and the severity of symptoms. The VHI proves to be an important tool for assessing the voice from the patient's perspective.

Complex thinking, towards a new understanding of reality
This reflective article aims to unravel the concept of complexity from the beginnings of science, which originates from a positivist paradigm that reduces the subject and the environment into objectified categories, giving rise to complex thought to articulate those domains of knowledge that have been fragmented. Likewise, some characteristics of complexity sciences are presented, which seek to identify the reasons why a system is complex, in addition to understanding reality from an epistemic framework guided by ethical and political criteria. Thus, this new multidimensional paradigm, which requires the nature of timely, ecological, historical, and contextual knowledge, must address the challenges of today's society.

Design and validation of a psychometric scale to measure social media addiction in university students
INTRODUCTION: This research article seeks to evaluate, through the development and validation of a brief psychometric scale, the level of addiction to directed social networks present in two groups of university students, from the psychology and graphic design programs at the University of Santander, Cúcuta Campus. A descriptive quantitative methodology was applied to the instrument, performing a reliability analysis, discarding items, designing the structural model, confirmatory factor analysis, adjustment and verification of modeling. METHOD: A quantitative and descriptive approach, in turn presents a Likert scale, which gave way to the application and analysis of results of the scale applied to a total of 132 students. RESULTS: The data found in the initial and final evaluation were analyzed and compared through the SPSS program, where the level of reliability of the test could be observed according to Cronbach's alpha of (a 0.894), thus demonstrating that it is a reliable instrument. Likewise, the test is composed of 29 items, resulting in the factorial analysis under 3 dimensions: use (9 items), frequency (13 items), and content (7 items)

Effectiveness of the “STARMOTRIX” treatment in strengthening motor processes in university students.
Introduction: The present investigation aims to evaluate the oculomotor capacity and coordination of students from a private university through the "2-arm Star" test, carry out the "STARMOTRIX" procedure through interventions aimed at convenient performance and efficient development of the body and visomotor coordination, to finally compare the initial results with a measurement after the application of the procedure; Method: It is quantitative in nature, in parallel it shows a pre-experimental design, with a retrospective cross-section, the effectiveness of 5 individual interventions is evaluated for each participant, where each lasted on average 10 minutes; The sample are students from a private university. Results: The data found in the initial and final evaluation were analyzed and compared using SPSS software. Each of the premises are null (there is a statistically significant difference), since the results were less than 0.05. Analysis and Discussion: This research contributes to the current literature, which has focused on children and older adults, regarding the measurement and intervention of this skill in adolescents and young adults. Therefore, it could be the beginning of future adaptations and studies that enable the description, design, and execution of strategies to train motor coordination and laterality in the target population. Conclusions: An improvement in the results after the "STARMOTRIX" treatment was evident in visomotor skills in psychology students at a private university, finding a significant difference between the results of the pre-test and the post-test. In addition, relevant aspects are identified that allow establishing parameters for future research and that are directly related to contextual factors and stimuli specific to the administration of the test.

Construction of scale that measures the perception of infections and sexually transmitted diseases in Young adults
The objective of this study was to construct a scale to measure the perception of sexually transmitted infections and diseases in young adults at a private university. The methodology used was quantitative and simple random sampling was applied to obtain a sample of 101 participants. A Likert scale of 54 items was implemented, distributed in 4 dimensions: venereal diseases, causes of infection, methods of care and consequences of sexually transmitted diseases. The psychometric results showed a high level of reliability of the scale, with a Cronbahc alpha coefficient (a) equal to or higher than 0.934. In addition, statistically significant associations were found, indicating a good internal consistency of the scale.

Protective effect of caffeine in Parkinson's disease: Systematic review
INTRODUCTION: Parkinson's disease is characterized by the loss of pigmented dopaminergic neurons of the para compacta of the substantia nigra, which provide dopaminergic innervation to the striatum. These two structures are part of the basal ganglia. For the typical symptoms of the disease to begin to manifest, there must be a neuronal loss of at least 80%. Many studies have established the relationship between Parkinson's and caffeine, mainly because caffeine acts on A2 adenosine receptors in D2 dopaminergic neurons present in the substantia nigra, demonstrating its neuroprotective effect. METHODS: A systematic review was carried out in PubMed, a reliable and specialized database in health sciences, in which quantitative reviews of the consumption or administration of caffeine and its protective effect in Parkinson's disease were sought from the year 2013 to the year 2023. RESULTS: Of the total articles selected for our study, 2 groups were disaggregated, the first group contemplates a sample of patients diagnosed with PD in an early stage and the second is based on a sample of patients diagnosed with PD in a late stage. the association of both groups was analyzed by means of a forest diagram. CONCLUSION: The systematic review and each one of the articles considered for the execution of this work support the original hypothesis that coffee does have protective effects in Parkinson's disease, indicating that coffee is an effective treatment.
