RESUMO

India's commercial advancement and development depend heavily on agriculture. A common fruit grown in tropical settings is citrus. A professional judgment is required while analyzing an illness because different diseases have slight variati ons in their symptoms. In order to recognize and classify diseases in citrus fruits and leaves, a customized CNN - based approach that links CNN with LSTM was developed in this research. By using a CNN - based method, it is possible to automatically differenti ate from healthier fruits and leaves and those that have diseases such fruit blight, fruit greening, fruit scab, and melanoses. In terms of performance, the proposed approach achieves 96% accuracy, 98% sensitivity, 96% Recall, and an F1 - score of 92% for ci trus fruit and leave identification and classification and the proposed method was compared with KNN, SVM, and CNN and concluded that the proposed CNN - based model is more accurate and effective at identifying illnesses in citrus fruits and leaves.


El avance y desarrollo comercial de India dependen en gran medida de la agricultura. Un tipo de fruta comunmente cultivada en en tornos tropicales es el cítrico. Se requiere un juicio profesional al analizar una enfermedad porque diferentes enfermedades tienen ligeras variaciones en sus síntomas. Para reconocer y clasificar enfermedades en frutas y hojas de cítricos, se desarrolló e n esta investigación un enfoque personalizado basado en CNN que vincula CNN con LSTM. Al utilizar un método basado en CNN, es posible diferenciar automáticamente entre frutas y hojas más saludables y aquellas que tienen enfermedades como la plaga de frutas , el verdor de frutas, la sarna de frutas y las melanosis. En términos de desempeño, el enfoque propuesto alcanza una precisión del 96%, una sensibilidad del 98%, una recuperación del 96% y una puntuación F1 del 92% para la identificación y clasificación d e frutas y hojas de cítricos, y el método propuesto se comparó con KNN, SVM y CNN y se concluyó que el modelo basado en CNN propuesto es más preciso y efectivo para identificar enfermedades en frutas y hojas de cítricos.

RESUMO

Introducción Los factores de riesgo psicosociales como determinantes de la salud en el trabajo pueden afectar tanto al bienestar físico como al bienestar psíquico del trabajador. En los sistemas de formación que incluyen contenidos cognitivo-preventivos, funcionan mejor cuando la construcción del conocimiento está basada en el neuroaprendizaje. El objetivo del estudio fue comparar el grado de procesamiento de contenidos con inserción de frases disuasivas (grupo A) versus inserción de frases persuasivas (grupo B), como efecto de una capacitación con aproximación al neuroaprendizaje de la salud psicosocial en el trabajo de un grupo de profesionales con seguro sanitario de la Amazonía peruana. Métodos Diseño experimental con pre/posprueba, que incluyó dos grupos experimentales más un grupo de control: n = 48 sujetos en total, 16 por cada grupo, con edades entre 22 y 36 años. La capacitación se desarrolló entre diciembre de 2018 y enero de 2019 con una duración de 18 horas, espaciadas en seis semanas. Para la recogida de datos se utilizó un registro previamente validado por cinco expertos. Resultados La distribución de datos en los grupos fue adecuada tanto en preprueba como en posprueba, excepto en posprueba del grupo B (p = 0,002). En el grupo control los resultados del procesamiento de contenidos, tanto preprueba como en posprueba, se mantuvieron similares (p = 0,667). El procesamiento de contenidos sobre salud psicosocial en el trabajo en posprueba fue significativamente diferente entre los grupos de intervención y el grupo control (p = 0,001), distinguiéndose el procesamiento de contenidos con inserción de frases disuasivas. Conclusiones Los resultados indican que la capacitación con aproximación al neuroaprendizaje, puede mejorar el procesamiento de contenidos con inserción de frases disuasivas para el cumplimiento de normativas orientadas a promover la salud psicosocial en el trabajo.


Introduction Psychosocial risk factors as determinants of health at work can affect both the physical and psychological well-being of the worker. Training systems that include cognitive-preventive content work best when knowledge construction is based on neurolearning. The purpose of this study was to compare the degree of content processing with the insertion of deterrent (group A) versus persuasive sentences (group B) as an effect of a training with a neurolearning approach to psychosocial health in the work of a group of professionals with health insurance in the Peruvian Amazon. Methods Experimental design with pre-/post-test, including two experimental groups plus a control group, n = 48 subjects in total and 16 per group, aged 22-36 years. The training took place between December 2018 and January 2019 with a duration of 18 hours spaced over six weeks. A register previously validated by five experts was used for data collection. Results The distribution of data in the groups was adequate in both pre-test and post-test, except in post-test in group "B" (p = 0.002). In the control group, the results of content processing in both pre-test and post-test remained similar (p = 0.667). The processing of psychosocial occupational health content in the post-test was significantly different between the intervention and control groups (p = 0.001), distinguishing the processing of content with the insertion of deterrent phrases. Conclusions The results indicate that training with a neurolearning approach can improve the processing of content with the insertion of deterrent phrases for compliance with regulations aimed at promoting psychosocial health at work.

RESUMO

ABSTRACT Purpose To address the need for a standardized assessment tool for assessing cognitive-communication abilities among Indian preschoolers, the current study aimed at describing a Delphi based development and validation process for developing one such tool. The objectives of the research were to conceptualize and construct the tool, validate its content, and assess its feasibility through pilot testing. Methods The study followed a Delphi approach to develop and validate the tool across four phases i.e. conceptualization; construction; content validation; and pilot testing. The first three phases were performed with a panel of six experts including speech-language pathologists and preschool teachers while the pilot testing was done with 20 typically developing preschoolers. A literature review was also conducted with the Delphi rounds to support the developmental process. Results The first two rounds of the Delphi aided in the construction of a culturally and linguistically suitable story-based cognitive-communication assessment tool with the memory (free recall, recognition, and literary recall) and executive function (reasoning, inhibition, and switching) related tasks relevant for preschoolers. The content validation of the tool was continued with the experts till the revisions were satisfactory and yielded an optimum Content Validity Index. The pilot test of the finalized version confirmed its feasibility and appropriateness to assess developmental changes in the cognitive-communication abilities of preschoolers. Conclusion The study describes the Delphi-based conceptualization, construction, content validation, and feasibility check of a tool to assess cognitive-communication skills in preschool children.

RESUMO

Abstract Objective This study investigated the effects of WN on LE in subjects with chronic tinnitus and normal hearing thresholds. The study was a prospective, non-randomized, before-and-after, intra-participant intervention. Methods Twenty-five subjects performed the following tests: conventional and high-frequency audiometry, acuphenometry, screening questionnaires for depression and anxiety symptoms, Tinnitus Handicap Inventory (THI), Montreal Cognitive Assessment, and high WM test from the Working Memory Assessment Battery, Federal University of Minas Gerais (WMAB) as the LE measure in two conditions: No Added Noise (NAN) and with Added Noise (AN). Results Seventeen participants (68%) performed better on AN condition. Data analysis revealed a 45% improvement in the WMAB total span count on AN setting, with a significant p value (p = 0.001). Conclusion The subgroup of participants without traces of anxiety symptoms, up to mild traces of depressive symptoms, having unilateral tinnitus, and a THI level up to grade 2, had improved WM performance in the presence of WN, which suggests a release of cognitive resources and less auditory effort under these combined conditions. Evidence level 4.

RESUMO

Aim To investigate the effect of safflower yellow (SY) on learning and memory ability of APP/ PS1 mice at different disease stages, and to explore the mechanism of SY anti- Alzheimer's disease by using 3-,6- and 9-month-old APP/PS 1 transgenic mice as experimental animal models. Methods Behavioral experiments were conducted to observe the effects of SY on learning and memory of APP/PS1 mice of different months. ELISA was used to detect the effect of SY on the expression of inflammatory factors in cortex of mice of different months. Western blot was used to detect the microglia activation marker protein, and its mechanism of action was further analyzed. Results SY could enhance the learning and memory ability of mice aged 3, 6 and 9 months, reduce the content of IL-6 and increase the content of TGF-β1 in brain tissue, up-regulate the expression levels of arginase-1 (arg-1) and triggering receptor expressed on myeloid cells 2 (tREM2) in brain tissue of mice of different months, and down-regulate the expression levels of inducible nitric oxide synthase (iNOS), Toll-like receptors 4 (tlr4) and nuclear factor-kappa B (nf-KB). Conclusions Compared with 3- and 9-month-old mice, SY is the most effective in improving learning memory in 6-month-old APP/PS1 mice. SY inhibits TLR4/NF-KB pathway activation by inducing TREM2 expression in brain tissue of APP/PS 1 transgenic mice, promotes microglia phenotype shift to anti-inflammatory phenotype, reduces chronic neuroinflammatory response, and improves learning memory in APP/PS1 mice at all months of age.

RESUMO

ObjectiveTo investigate the effect of multi-target transcranial direct current stimulation (tDCS) and single-target tDCS on the performance of working memory-postural control dual-task in healthy adults, and to compare the regulatory effect of the two stimulation protocols. MethodsFrom November, 2020 to February, 2021, 19 healthy adults in Shanghai University of Sport were recruited and randomly accepted multi-target tDCS, single-target tDCS and sham stimulation with at least one week interval between any two stimulation protocols. The target areas of multi-target tDCS included left dorsal lateral prefrontal cortex (L-DLPFC) and bilateral primary motor cortex (M1), and single-tDCS only applied to L-DLPFC. Before and after stimulation, participants completed walking and standing balance tests under single task and dual-task conditions with the second task being a N-back task. The dual-task postural control performance, dual-task cost (DTC) and working memory performance were observed before and after stimulation. ResultsSignificant differences were observed among three stimulation protocols in the changes of stride variability (F = 3.792, P = 0.029), DTC of stride variability (F = 3.412, P = 0.040) and velocity of center of pressure (Vcop) (F = 3.815, P = 0.029). The stride variability (P = 0.047) and Vcop (P = 0.015) were significantly lower and the decrease in DTC of stride variability tended to be significant (P = 0.073) following multi-target tDCS, as compared to sham stimulation. Single-target tDCS significantly decreased the changes of stride variability (P = 0.011), DTC of stride variability (P = 0.014) and Vcop (P = 0.025), as compared to sham stimulation. Compared with single target tDCS, multi-target tDCS reduced the changes of the dual-task cost of the area of center of pressure (P = 0.035). Moreover, no significant difference was observed among the three stimulation protocols in the changes of each measure in the working memory test (P > 0.05). ConclusionBoth multi-target tDCS and single-target tDCS can improve the performance of working memory-postural control dual-task in healthy adults, and compared with single-target tDCS, multi-target tDCS has some advantages in regulating postural control.

RESUMO

Alzheimer's disease (AD) is a leading cause of dementia in the elderly. Mitogen-activated protein kinase phosphatase 1 (MKP-1) plays a neuroprotective role in AD. However, the molecular mechanisms underlying the effects of MKP-1 on AD have not been extensively studied. MicroRNAs (miRNAs) regulate gene expression at the post-transcriptional level, thereby repressing mRNA translation. Here, we reported that the microRNA-429-3p (miR-429-3p) was significantly increased in the brain of APP23/PS45 AD model mice and N2AAPP AD model cells. We further found that miR-429-3p could downregulate MKP-1 expression by directly binding to its 3'-untranslated region (3' UTR). Inhibition of miR-429-3p by its antagomir (A-miR-429) restored the expression of MKP-1 to a control level and consequently reduced the amyloidogenic processing of APP and Aβ accumulation. More importantly, intranasal administration of A-miR-429 successfully ameliorated the deficits of hippocampal CA1 long-term potentiation and spatial learning and memory in AD model mice by suppressing extracellular signal-regulated kinase (ERK1/2)-mediated GluA1 hyperphosphorylation at Ser831 site, thereby increasing the surface expression of GluA1-containing α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors (AMPARs). Together, these results demonstrate that inhibiting miR-429-3p to upregulate MKP-1 effectively improves cognitive and synaptic functions in AD model mice, suggesting that miR-429/MKP-1 pathway may be a novel therapeutic target for AD treatment.

RESUMO

Recent clinical studies have shown that mutation of phosphatase and tensin homolog deleted on chromosome 10 (PTEN) gene in cancer cells may be associated with immunosuppressive tumor microenvironment (TME) and poor response to immune checkpoint blockade (ICB) therapy. Therefore, efficiently restoring PTEN gene expression in cancer cells is critical to improving the responding rate to ICB therapy. Here, we screened an adeno-associated virus (AAV) capsid for efficient PTEN gene delivery into B16F10 tumor cells. We demonstrated that intratumorally injected AAV6-PTEN successfully restored the tumor cell PTEN gene expression and effectively inhibited tumor progression by inducing tumor cell immunogenic cell death (ICD) and increasing immune cell infiltration. Moreover, we developed an anti-PD-1 loaded phospholipid-based phase separation gel (PPSG), which formed an in situ depot and sustainably release anti-PD-1 drugs within 42 days in vivo. In order to effectively inhibit the recurrence of melanoma, we further applied a triple therapy based on AAV6-PTEN, PPSG@anti-PD-1 and CpG, and showed that this triple therapy strategy enhanced the synergistic antitumor immune effect and also induced robust immune memory, which completely rejected tumor recurrence. We anticipate that this triple therapy could be used as a new tumor combination therapy with stronger immune activation capacity and tumor inhibition efficacy.

RESUMO

The prefrontal cortex and hippocampus may support sequential working memory beyond episodic memory and spatial navigation. This stereoelectroencephalography (SEEG) study investigated how the dorsolateral prefrontal cortex (DLPFC) interacts with the hippocampus in the online processing of sequential information. Twenty patients with epilepsy (eight women, age 27.6 ± 8.2 years) completed a line ordering task with SEEG recordings over the DLPFC and the hippocampus. Participants showed longer thinking times and more recall errors when asked to arrange random lines clockwise (random trials) than to maintain ordered lines (ordered trials) before recalling the orientation of a particular line. First, the ordering-related increase in thinking time and recall error was associated with a transient theta power increase in the hippocampus and a sustained theta power increase in the DLPFC (3-10 Hz). In particular, the hippocampal theta power increase correlated with the memory precision of line orientation. Second, theta phase coherences between the DLPFC and hippocampus were enhanced for ordering, especially for more precisely memorized lines. Third, the theta band DLPFC → hippocampus influence was selectively enhanced for ordering, especially for more precisely memorized lines. This study suggests that theta oscillations may support DLPFC-hippocampal interactions in the online processing of sequential information.

RESUMO

ObjectiveTo investigate the effects of Jiaohong pills (JHP) and its prescription, Pericarpium Zanthoxyli (PZ) and Rehmanniae Radix (RR) cognitive dysfunction in scopolamine-induced Alzheimer's disease (AD) mice and its mechanism through pharmacodynamic and metabolomics study. MethodThe animal model of AD induced by scopolamine was established and treated with PZ, RG and JHP, respectively. The effects of JHP and its formulations were investigated by open field test, water maze test, object recognition test, avoidance test, cholinergic system and oxidative stress related biochemical test. Untargeted metabolomics analysis of cerebral cortex was performed by ultra-performance liquid chromatography-Quadrupole/Orbitrap high resolution mass spectrometry (UPLC Q-Exactive Orbitrap MS). ResultThe behavioral data showed that, compared with the model group, the discrimination indexes of the high dose of JHP, PZ and RR groups was significantly increased (P<0.05). The staging rate of Morris water maze test in the PZ, RR, high and low dose groups of JHP was significantly increased (P<0.05, P<0.01), the crossing numbers in the PZ, JHP high and low dose groups were significantly increased (P<0.05, P<0.01); the number of errors in the avoidance test were significantly reduced in the PZ and high-dose JHP groups (P<0.01), and the error latencies were significantly increased in the JHP and its prescription drug groups (P<0.01). Compared with the model group, the activities of acetylcholinesterase in the cerebral cortex of the two doses of JHP group and the PZ group were significantly increased (P<0.05, P<0.01), and the activity of acetylcholinesterase in the high-dose JHP group was significantly decreased (P<0.05), and the level of acetylcholine was significantly increased (P<0.01). At the same time, the contents of malondialdehyde in the serum of the two dose groups of JHP decreased significantly (P<0.05, P<0.01). The results of metabolomics study of cerebral cortex showed that 149 differential metabolites were identified between the JHP group and the model group, which were involved in neurotransmitter metabolism, energy metabolism, oxidative stress and amino acid metabolism. ConclusionJHP and its prescription can antagonize scopolamine-induced cognitive dysfunction, regulate cholinergic system, and reduce oxidative stress damage. The mechanism of its therapeutic effect on AD is related to the regulation of neurotransmitter, energy, amino acid metabolism, and improvement of oxidative stress.

RESUMO

Objetivo: compreender como a pandemia de COVID-19 afetou a vida e a saúde das mulheres, com ênfase nos aspectos da saúde sexual e reprodutiva, e refletir sobre os direitos sexuais e reprodutivos e a justiça reprodutiva no contexto da crise sanitária. Metodologia: utilizou-se questionário online com 113 perguntas objetivas e uma questão aberta para comentários. De 8.313 mulheres que responderam ao questionário, 1.838 relataram suas vivências durante a pandemia na questão aberta. Esse material passou por técnicas de análise narrativa e temática e de construção de memória. Resultados: evidenciou-se a ampliação das dificuldades de acesso a serviços de saúde, em especial de saúde sexual e reprodutiva; o aprofundamento das iniquidades na divisão sexual do trabalho, com sobrecarga de trabalho doméstico e profissional; a insegurança econômica; o tensionamentos das relações afetivo-sexuais e maior exposição à violência; e importantes repercussões na saúde psicoemocional. Todos esses aspectos afetaram as experiências de saúde e adoecimento; a vida sexual; e os planos e experiências reprodutivas nos primeiros anos de pandemia. Conclusão: no Brasil, na sobreposição da emergência sanitária com a crise democrática de direitos, fatos sociais e fatos fisiológicos se misturam e se totalizam na experiência histórica e material do corpo sexual e reprodutivo das mulheres, seguindo as linhas de força das precariedades e injustiças de gênero, de raça e de classe. Os relatos das mulheres contribuem para a construção de uma memória coletiva ­não necessariamente unívoca e linear ­da pandemia. Memórias que podem não apenas ilustrar o momento presente, como contribuir para o entendimento e enfrentamento de crises semelhantes futuras.


Objective: this study seeks to comprehend the impact of the COVID-19 pandemic on women's lives and health, with a particular focus on sexual and reproductive health, andto reflect on sexual and reproductive rights and reproductive justice within the context of the health crisis.Methods:employing an online questionnaire featuring 113 objective questions and one open-ended question for free comments, the study gathered responses from 8,313 women. Out of these, 1,838 utilized the open question to articulate their experiences during the pandemic. The collected material underwent analysis using narrative and thematic approaches, along with memory construction techniques.Results:the findings indicate heightened challenges in accessing health services, particularly for sexual and reproductive health. The pandemic deepened inequities in the sexual division of labor, leading to increased domestic and professional workloads, economic insecurity, elevated tensions in affective-sexual relationships, greater exposure to violence, and notable repercussions on psycho-emotional health. These factors collectively influenced women's health/illness experiences, sexual lives, and reproductive plans during the initial years of the pandemic. Conclusion: the intersection of the health crisis with a democratic crisis in rights has intertwined social and physiological factors into the historical and material experiences of women's sexual and reproductive bodies. These experiences follow the trajectories of gender, race, and class-based precariousness and injustices. Women's accounts contribute to the construction of a collective memory of the pandemic that is not necessarily uniform or linear. Beyond illustrating the present moment, these memories aid in understanding and addressing similar crises in the future.

RESUMO

Objective: To develop a classification framework based on random forest (RF) modeling to outline the declarative memory profile of patients with panic disorder (PD) compared to a healthy control sample. Methods: We developed RF models to classify the declarative memory profile of PD patients in comparison to a healthy control sample using the Rey Auditory Verbal Learning Test (RAVLT). For this study, a total of 299 patients with PD living in the city of Rio de Janeiro (70.9% females, age 39.9 ± 7.3 years old) were recruited through clinician referrals or self/family referrals. Results: Our RF models successfully predicted declarative memory profiles in patients with PD based on RAVLT scores (lowest area under the curve [AUC] of 0.979, for classification; highest root mean squared percentage [RMSPE] of 17.2%, for regression) using relatively bias-free clinical data, such as sex, age, and body mass index (BMI). Conclusions: Our findings also suggested that BMI, used as a proxy for diet and exercises habits, plays an important role in declarative memory. Our framework can be extended and used as a prospective tool to classify and examine associations between clinical features and declarative memory in PD patients.

RESUMO

Objective: To investigate risk factors associated with impaired attention-related executive functions (EFs) at age 11 and working memory at age 15. Methods: Data from participants of the population-based 2004 Pelotas Birth Cohort at ages 11 (n=3,582) and 15 (n=1,950) were analyzed. The study measured attentional control, cognitive flexibility, and selective attention using the Test of Everyday Attention for Children (TEA-Ch). Spatial working memory was assessed by the Cambridge Neuropsychological Test Automated Battery (CANTAB). Logistic regression was employed to explore the relationship between perinatal and childhood exposures and EF impairment. Results: Low maternal education had a significant negative impact on EFs. At age 11, it was associated with decreased attentional control (OR = 3.04; 95%CI 2.09-4.43), and at age 15, it was linked to impaired spatial working memory (OR = 2.21; 95%CI 1.58-3.09). Additional risk factors included low household income, black or brown maternal skin color, high parity, prematurity, low birth weight, and multiple siblings. Breastfeeding, regardless of duration, was found to be a protective factor against impaired cognitive flexibility (OR = 0.38; 95%CI 0.22-0.65). Conclusion: This study underscores the lasting impact of perinatal exposures on EF development. Policies that mitigate the negative effects of risk factors and promote EF development, especially among vulnerable populations, are needed.

RESUMO

El objetivo de este artículo es describir las percepciones de estudiantes y padres de familia relacionadas con el conflicto armado y la paz. Corresponde a un estudio cualitativo de nivel descriptivo enmarcado en el paradigma interpretativo-hermenéutico. Se emplearon los métodos análisis de discurso y teoría fundamentada, y se contó con la participación de 35 actores escolares de una institución educativa en Colombia, a quienes se les aplicó una entrevista en profundidad. Los datos fueron codificados y categorizados, y sistematizados a través del software Atlas Ti. Los resultados muestran siete categorías selectivas, 18 códigos axiales y 231 códigos abiertos, los cuales develan las distintas formas de percepción en torno a la paz y al conflicto armado de los actores escolares. Se sugieren gramáticas heterogéneas en torno a la paz y el conflicto armado con marcos interpretativos amplios y estrategias de escucha flexibles.


The objective of the article is to describe the perceptions of students and parents related to the armed conflict and peace. It corresponds to a qualitative study of descriptive level, framed in the interpretive-hermeneutical paradigm. Discourse analysis and grounded theory methods were used, and 35 school actors from an educational institution in Colombia participated, to whom an in-depth interview was applied. The data was coded, categorized, and systematized through the Atlas Ti software. The results show seven selective categories, 18 axial codes, and 231 open codes, which reveal the different forms of perception around peace and armed conflict of school actors. Heterogeneous grammars are suggested around peace and armed conflict with broad interpretive frameworks and flexible listening strategies.

RESUMO

(analítico) Se presentan los resultados de una investigación que buscó conocer las maneras como los jóvenes construyen sus ideas e imaginarios sobre el pasado reciente en Colombia. El proyecto fue desarrollado en la ciudad de Manizales y contó con la participación de 24 jóvenes entre los 12 y 18 años de edad. El estudio se desarrolló por medio de cartografías de experiencias que se vinculan al pasado reciente y la reconstrucción de la memoria colectiva. Se encontró que los jóvenes emplean signos que se han utilizado tradicionalmente para representar la paz y la memoria, además, que los procesos dialógicos y creativos favorecen los espacios de reflexión en los cuales se trascienden estos signos y se construyen significados más amplios que a su vez les permiten narrar experiencias de vida.


(analytical) This article presents the results of a research project that sought to understand the ways in which young people construct their ideas and imaginaries about the recent past in Colombia. The research was conducted in the city of Manizales with the participation of 24 young people between 12 and 18 years of age. The research was carried out using cartographies of experiences from the recent past and the reconstruction of collective memory. It was identified that young people use signs that have been traditionally used to represent peace and memory. Dialogue and creative processes generate reflection spaces in which these signs are transcended and broader meanings are constructed, which in turn allow them to narrate their life experiences.

RESUMO

Abstract Emerging studies indicate the persistence of symptoms beyond the acute phase of COVID-19. Cognitive impairment has been observed in certain individuals for months following infection. Currently, there is limited knowledge about the specific cognitive domains that undergo alterations during the post-acute COVID-19 syndrome and the potential impact of disease severity on cognition. The aim of this review is to examine studies that have reported cognitive impairment in post-acute COVID-19, categorizing them into subacute and chronic phases. The methodology proposed by JBI was followed in this study. The included studies were published between December 2019 and December 2022. The search was conducted in PubMed, PubMed PMC, BVS - BIREME, Embase, SCOPUS, Cochrane, Web of Science, Proquest, PsycInfo, and EBSCOHost. Data extraction included specific details about the population, concepts, context, and key findings or recommendations relevant to the review objectives. A total of 7,540 records were identified and examined, and 47 articles were included. The cognitive domains most frequently reported as altered 4 to 12 weeks after acute COVID-19 were language, episodic memory, and executive function, and after 12 weeks, the domains most affected were attention, episodic memory, and executive function. The results of this scoping review highlight that adults with post-acute COVID-19 syndrome may have impairment in specific cognitive domains.


Resumo Estudos emergentes indicam a persistência dos sintomas além da fase aguda da COVID-19. O comprometimento cognitivo foi observado em alguns indivíduos durante meses após a infecção. Atualmente, há pouco conhecimento sobre os domínios cognitivos específicos que sofrem alterações durante a síndrome pós-aguda da COVID-19 e o possível impacto da gravidade da doença na cognição. O objetivo desta revisão é examinar estudos que relataram comprometimento cognitivo na COVID-19 pós-aguda, categorizando-os em fases subaguda e crônica. A metodologia proposta pela Joanna Briggs Institute foi seguida neste estudo. Os estudos incluídos foram publicados entre dezembro de 2019 e dezembro de 2022. A busca foi realizada no PubMed, PubMed PMC, BVS - BIREME, Embase, SCOPUS, Cochrane, Web of Science, Proquest, PsycInfo e EBSCOHost. A extração de dados incluiu detalhes específicos sobre a população, os conceitos, o contexto e as principais descobertas ou recomendações relevantes para os objetivos da revisão. Um total de 7.540 registros foi identificado e examinado, e 47 artigos foram incluídos. Os domínios cognitivos mais frequentemente relatados como alterados de 4 a 12 semanas após a COVID-19 aguda foram linguagem, memória episódica e função executiva e, após 12 semanas, os domínios mais afetados foram atenção, memória episódica e função executiva. Os resultados dessa revisão de escopo destacam que adultos com síndrome pós-aguda da COVID-19 podem apresentar comprometimento em domínios cognitivos específicos.

RESUMO

Introducción. En Chile las tasas de sedentarismo infantil han aumentado, siete de cada 10 niños no cumple con los estándares mínimos recomendados por la Organizaciónn Mundial de la Salud. Faltan en Chile estudios que asocien el sedentarismo de tiempo libre y las horas sedentes en jornada escolar con las habilidades cognitivas. Objetivo. Determinar los cambios en las habilidades cognitivas posterior a la realización de quiebres en la conducta sedentaria. Métodos. Participaron 83 alumnos de 12 a 14 años, pertenecientes a 7° y 8° básico de la región metropolitana de Santiago de Chile. Los alumnos fueron distribuidos aleatoriamente como casos (42) y control (41). Se realizó durante 10 días, un protocolo de quiebres en la conducta sedentaria de 3 minutos cada 40 minutos, durante toda la jornada escolar. Ambos grupos tuvieron evaluaciones fisiológicas y aplicación de test de memoria y atención pre y post intervención. Resultados. Se encontraron diferencias estadísticamente significativas en la variable de atención con un valor p-value de (< 0,005) a favor del grupo intervenido. En valores de presión arterial sistólica y frecuencia cardiaca se evidencio un descenso significativo en el grupo intervenido (p<0,005) Conclusión. En este estudio se demuestra que el protocolo aplicado, mejora la habilidad cognitiva de atención en la población estudiada y además se reducen los valores de parámetros fisiológicos.


Background. In Chile, child sedentary lifestyle rates have increased; seven out of 10 children do not meet the minimum standards recommended by the World Health Organization. There is a lack of studies in Chile that associate free-time sedentary behavior and seated hours during the school day with cognitive skills. Objective. To determine the changes in cognitive abilities after the completion of sedentary behavior breaks. Methods. 83 students from 12 to 14 years old participated, belonging to 7th and 8th grade of the metropolitan region of Santiago de Chile. Students were randomly distributed as cases (42) and control (41). A protocol of sedentary behavior breaks of 3 minutes every 40 minutes was carried out during 1 week, during the whole school day. Both groups had physiological evaluations and application of memory tests and pre and post intervention care. Results. Statistically found differences were found both in the care variables with a p-value of <0.005 in favor of the intervened group, as well as in the systolic blood pressure and heart rate values evidencing a significant decrease in the intervened group (p < 0.005) Conclusion. This study shows that the applied protocol improves the cognitive ability of attention in the studied population and also reduces values of physiological parameters.

RESUMO

Busca-se discutir a relação da Experiência de Quase Morte (EQM) a partir dos conceitos junguianos, particularmentea Individuação e a Espiritualidade. Pretende-se ainda, explorar possíveis relações entre a memória da EQM e Neuropsicologia, analisando o arquétipo psicóide e possíveis relações entre ele e a memória episódica, procurando-se possibilidades viáveis de pesquisas exploratórias que possam trazer maiores esclarecimentos na relação entre a experiência de quase morte, o conceito do psicóide da Psicologia analítica de C. G. Jung e a memória episódica tratada em neuropsicologia AU


We seek to discuss the relationship of the Near Death Experience (NDE) from the Jungian concepts, particularly Individuation and Spirituality. It is also intended to explore possible relationships between NDE memory and Neuropsychology, analyzing the psychoid archetype and possible relationships between it and episodic memory, looking for viable possibilities for exploratory research that can bring further clarification on the relationship between the experience of almost death, the psychoid concept from C. G. Jung's Analytical Psychology and the episodic memory treated in neuropsychology AU

RESUMO

O projeto de pesquisa-intervenção As narrativas ficcionais e o cuidado à dor crônica atuou no Setor de Dor e Cuidados Paliativos de um hospital público, oferecendo-se como coadjuvante do cuidado em saúde. O Ateliê Jardim de Histórias foi um de seus dispositivos e propôs o bordado inventado como linhas de sustentação para um fazer compartilhado. No contexto latinoamericano, o bordar remete à transmissão transgeracional e a práticas políticas e processos de luta e luto no laço social. Este artigo propõe recuperar a história do bordado para além da perspectiva colonial e, a partir disso, a-bordar essa experiência da pesquisa-intervenção no hospital e suas possibilidades. Entende-se que o bordado inventado ressalta a dimensão de improviso e de criatividade dessa prática enquanto um suporte afetivo para a tessitura de narrativas, a partir da disposição de estar com o outro em torno de um fazer sem prescrições.

The research-intervention project Fictional narratives and chronic pain careacted in the Sector of Pain and Palliative Care of a public hospital, offering an adjunct to health care. The Garden of Stories Atelierwas one of its devices, which proposed the invented embroidery as threads of support for a shared work. In Latin America, embroidery refers to transgenerational transmission, and to political practices and processes of struggle and mourning in the social bond. This article aims to retrieve the history of embroidery beyond the colonial perspective and, from there, to approach this experience of research-intervention in the hospital and its possibilities. The invented embroidery is thought to emphasize the dimension of improvisation and creativity of this practice, as an affective support for the weaving of narratives, from the willingness to be together around an activity without prescriptions.
