Exposure to Smartphones and Tablets, Physical Activity and Sleep in Children From 5 to 10 Years Old: A Systematic Review and Meta-Analysis.

OBJECTIVE: To conduct a systematic review and meta-analysis to verify the association between smartphone/tablet exposure and physical activity and sleep in children from 5 to 10 years old. Data Source: This study followed the guidelines of PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) and included studies that met eligibility criteria based on the "PECO" strategy: participants (children from 5 to 10 years old), exposure (smartphone and tablet use), and outcome (physical activity and sleep). STUDY INCLUSION AND EXCLUSION CRITERIA: The inclusion criteria were observational studies published in indexed scientific journals and written in Portuguese, English, and Spanish that verified the association of exposure to smartphones/tablets with physical activity and sleep in children aged 5 to 10 years of both sexes. Studies were considered eligible only if they met the previous criteria. Data Extraction: The search was conducted in January 2023 on databases from electronic journals without the restriction of the period. To meta-analyze were extracted and grouped using models of fixed and random effects, the coefficients Odds Ratio (OR), Beta (ß), Standard Error (SE), and Confidence Intervals of 95% (95%CI). Data Synthesis: 2396 potentially relevant papers were identified, and 17 met the inclusion criteria. RESULTS: It can be verified that there was an inverse association between smartphones with physical activity and sleep. Studies indicate that for every additional hour of smartphone and tablet use, sleep can be expected to decrease by an average of 11 minutes (ß = - 0.11; 95%CI = -0.13; -0.09). Children using smartphones and tablets were 1.79 times (OR = 1.79; 95%CI = 1.72-1.86) more likely to have shorter sleep duration and 1.53 times (OR = 1.53; 95%CI = 1.41-1.65) more likely to have worse sleep quality. Children with shorter smartphone and tablet usage were 1.19 times more likely to be active (OR = 1.19; 95% CI = 1.03-1.37). CONCLUSION: Children of 5 to 10 years who are more often exposed to smartphones and tablets are prone to have worse quality and quantity of sleep, as well as less practice of physical activity. Health promotion actions can be encouraged based on the results, aiming to reduce the use time of these devices and improve children's health and quality of life.

Self-Reported Home Program Adherence by People With Aphasia: Exploring Construct Validity.

PURPOSE: The study purpose was to compare the practice patterns captured by self-reported logbook data and those recorded by a computerized home program application. The current study is part of a larger single-case research design study aimed at investigating the effect of logbook use on home program adherence in people with aphasia poststroke. METHOD: Data from six adults with chronic aphasia with interest in improving their reading were used in this secondary analysis. Participants completed reading comprehension therapy tasks using a mobile application and tablet. The activities were self-directed and designed for people with aphasia to complete independently. We created an aphasia-friendly logbook based on best practices to allow participants to record their estimated total minutes practiced. Participants received instructions to practice the reading therapy application 80 min a day 7 days a week for the duration of the study. We calculated the difference in the total time per day recorded by each participant to the application data collected. RESULTS: All participants used the logbook to record their practice. There was a strong relationship between self-reported logbook practice and application-recorded practice for four of the six participants. Individual differences were noted and explored. CONCLUSION: These results suggest that some people with aphasia can use logbooks with aphasia-friendly modifications to accurately estimate the amount of practice completed outside of therapy sessions.

Development of a Mobile Application with Health Guidelines for TB Patients Care.

Health guidelines inform recommendations for different clinical practices or public health policies. They are a simple way to organize and retrieve relevant information that can impact patient care. Although these documents are easy to use, most are not user-friendly because they are difficult to access. Our work aims to present the developing approach for a decision-making tool based on health guidelines to assist health professionals in caring for patients with tuberculosis. This tool is being developed for use on mobile devices and as a web-based system, which will transform a passive and declarative health guideline document into an interactive tool that will provide data, information, and knowledge. User tests with functional prototypes developed for the Android platform show that this application has the potential to be applied in TB healthcare facilities in the future.

Introduction: screen use during childhood and potential harm concerns have increased in recent years. Advice not to allow more than two hours of screen use per day was contested during the COVID-19 pandemic. The primary purpose of this research was to probe the opinions and attitudes of professionals regarding the use of screens and to understand how these changed during the pandemic. Materials and methods: this exploratory study, with a qualitative approach and theory-based strategy, was made between 2020 and 2021, and involved the participation of 23 professionals (pediatricians and general practitioners) in four focus groups. The recorded material was analyzed for content interpretation. The analysis included generating codes that were grouped into five thematic areas. Results: the resulting axes were: 1) the issue of screens in the outpatient practice of healthy children; 2) perception of harm; 3) perception of benefits; 4) screens in times of Preventive and Compulsory Social Isolation (ASPO, for its acronym in Spanish); and 5) contradictory thoughts and actions on the use of screens. Discussion: when making recommendations regarding screen exposure, the interviewees' intuition predominated over available scientific evidence. They recognized that the ASPO context highlighted some of the benefits associated with the connectivity provided by these devices. Conclusion: our results show that awareness of screen displays is becoming increasingly neutral concerning the trade-off between their risks and benefits, prompting practitioners to become more flexible in their recommendations.

Eficacia de la terapia de estimulación cognitiva asistida por tecnología en pacientes con demencia / Efficacy of technology-assisted cognitive stimulation therapy in patients with dementia

De la mano del envejecimiento poblacional, la demencia o trastorno neurocognitivo mayor afecta a una cantidad cada vez mayor de personas, lo que implica un alto costo para los servicios de salud. Las guías de práctica clínica recomiendan ofrecer terapias de estimulación cognitiva a las personas afectadas y cada vez es más común el empleo de herramientas tecnológicas que permiten su aplicación a gran escala a pesar de la incertidumbre acerca de su beneficio.En este artículo revisamos la evidencia más actualizada sobre la eficacia de las herramientas computarizadas para el entrenamiento cognitivo de pacientes con demencia. Encontramos algunos estudios que sugieren que podría haber una posible mejora cognitiva en los pacientes con demencia y en la calidad de vida de sus cuidadores. Sin embargo, la mayoría de los estudios no fueron de buena calidad metodológica, fueron realizados con un número limitado de pacientes, en periodos poco prolongados, y los desenlaces fueron evaluados a través de múltiples pruebas de difícil interpretación. (AU)

With the increasing population aging, dementia or major neurocognitive disorder affects a growing number of people,incurring a substantial burden on healthcare services. Clinical practice guidelines recommend providing cognitive stimulation therapies to affected individuals, and the use of technological tools for implementing therapies on a large scale is increasingly common despite the uncertainty about their benefits.In this article, we reviewed the most up-to-date evidence on the effectiveness of computerized tools for cognitive training in patients with dementia. We found some studies that suggest that there could be a possible cognitive improvement in patients with dementia and in the quality of life of their caregivers. However, most studies were not of good methodological quality, were carried out with a limited number of patients, in short periods of time, and the outcomes were evaluated through multiple tests that were difficult to interpret.

The influence of whole-body vibration, media, and artificial lighting on eye-movement during reading / A influência da vibração de corpo inteiro, da mídia e da iluminação artificial no movimento dos olhos durante tarefas de leitura

ABSTRACT Objective: To evaluate if participants, subjected to whole-body vibration, two different types of media (paper versus tablet) and two lighting environments (fluorescent versus LED), present a difference in eye-movement parameters during reading tasks. Methods: Fourteen adults silently read two different texts in each one of the eight randomized testing conditions (whole-body vibration versus media versus lighting), resulting in 16 different texts read per individual. Whole-body vibration was applied in the vertical direction, 5Hz and 0.8 m/s2 root-mean-square amplitude, a condition similar to those experienced by forklift truck drivers. Participants were in a sitting position with a backrest. An eye-tracker evaluated the eye-movements during the reading task. Results: Whole-body vibration significantly reduced the number of ocular fixations, and cross-correlation; and increased the reading efficiency, fixation duration, directional attack, and binocular anomalies. Neither the type of media nor the lighting environment interfered significantly with the eye-movements, both in situations with and without vibration. Conclusion: The results indicate that whole-body vibration interfered in the eye-movements during the reading task. This may impose a difficulty to process the visual information and to synchronously coordinate the binocular movements under vibration environments.

RESUMO Objetivo: Avaliar se participantes submetidos à vibração de corpo inteiro, a dois tipos diferentes de mídia (papel versus tablet) e a dois ambientes de iluminação (fluorescente versus LED) apresentam diferença nos parâmetros de movimento dos olhos durante tarefas de leitura. Métodos: Quatorze adultos leram silenciosamente dois textos diferentes em cada uma das oito condições de teste (vibração de corpo inteiro versus mídia versus iluminação), de forma aleatória, resultando em 16 textos diferentes lidos por indivíduo. A vibração de corpo inteiro foi aplicada no sentido vertical, com amplitude de 5Hz e 0,8m/s² da raiz do valor quadrático médio, em condição semelhante às vivenciadas pelos motoristas de empilhadeiras. Os participantes permaneceram em postura sentada com encosto. Um rastreador ocular avaliou os movimentos oculares durante a leitura. Resultados: A vibração de corpo inteiro reduziu significativamente o número de fixações oculares e a correlação cruzada entre os olhos e aumentou a eficiência de leitura, duração da fixação, ataque direcional e anomalias binoculares. Nem o tipo de mídia nem as condições de ambientes de iluminação interferiram significativamente nos movimentos oculares, tanto em situações com ou sem vibração. Conclusão: Os resultados indicam que a Vibração de Corpo Inteiro pode interferir nos movimentos oculares durante a leitura. Isso pode impor uma dificuldade no processamento da informação visual e na coordenação síncrona dos movimentos binoculares em ambientes de vibração.

A new periocular dataset collected by mobile devices in unconstrained scenarios.

Recently, ocular biometrics in unconstrained environments using images obtained at visible wavelength have gained the researchers' attention, especially with images captured by mobile devices. Periocular recognition has been demonstrated to be an alternative when the iris trait is not available due to occlusions or low image resolution. However, the periocular trait does not have the high uniqueness presented in the iris trait. Thus, the use of datasets containing many subjects is essential to assess biometric systems' capacity to extract discriminating information from the periocular region. Also, to address the within-class variability caused by lighting and attributes in the periocular region, it is of paramount importance to use datasets with images of the same subject captured in distinct sessions. As the datasets available in the literature do not present all these factors, in this work, we present a new periocular dataset containing samples from 1122 subjects, acquired in 3 sessions by 196 different mobile devices. The images were captured under unconstrained environments with just a single instruction to the participants: to place their eyes on a region of interest. We also performed an extensive benchmark with several Convolutional Neural Network (CNN) architectures and models that have been employed in state-of-the-art approaches based on Multi-class Classification, Multi-task Learning, Pairwise Filters Network, and Siamese Network. The results achieved in the closed- and open-world protocol, considering the identification and verification tasks, show that this area still needs research and development.

A baseline measurement was taken with the subjects' current updated glasses. Accommodation amplitude (AA) and near point of convergence (NPC) were measured binocularly with the RAF ruler. DA was evaluated by a questionnaire. Results No significant difference (p=.52) was found for AA comparing baseline (11.50±1.88 D), test (11.61± 1.62 D), and control SV lenses (11.88±1.50 D). No significant difference was found for NPC (p=.94), between baseline (6.50 ± 2.89cm), test (6.71± 3.49) and control SV lenses (6.82± 3.50 cm). No significant difference was found comparing test and control SV lenses in symptoms of DA (p=0.20). Conclusions The +0.40 D lenses have no negative impact on convergence or loss of accommodation power. The +0.40 D and control SV lenses had a similar impact on attenuating symptoms of DA.

RESUMO Objetivo Avaliar os efeitos do uso de lentes oftálmicas com filtro seletivo de luz azul-violeta, sem e com poder adicional de + 0,4D na zona de perto nas funções de acomodação e convergência e para sintomas de astenopia digital (AD). Métodos Ensaio clínico controlado, randomizado e mascarado, com 49 voluntários (idade, 29 ± 5,5 anos; masculino: feminino, 18: 31). Cada participante usou lentes de teste (+0,40 D na zona de perto) e controle (visão simples), por 4 semanas de forma randomizada. Ambas as lentes tinham filtro seletivo de luz azul-violeta. A medição inicial (baseline) foi feita com os óculos atualizados de cada participante. A amplitude de acomodação (AA) e o ponto de convergência próximo (PPC) foram medidos binocularmente com a régua RAF. A AD foi avaliada por um questionário. Resultados Não houve diferença estatisticamente significante (p=0,52) para as medidas de AA comparando as lentes baseline (11,50±1,88 D), teste (11,61±1,62 D) e controle VS (11,88±1,50 D). Nenhuma diferença significativa foi encontrada para a medida do PPC (p=0,94), entre as lentes baseline (6,50 ± 2,89cm), teste (6,71±3,49) e controle VS (6,82±3,50 cm). Nenhuma diferença significativa foi encontrada comparando lentes teste de VS e controle nos sintomas de AD (p=0,20). Conclusões As lentes com +0,40 D não têm impacto negativo na convergência ou na perda de acomodação. As lentes +0,40 D e controle VS, tiveram impacto semelhante na redução dos sintomas de AD.

An Architecture for Collaborative Terrain Sketching with Mobile Devices.

3D terrains used in digital animations and videogames are typically created by several collaborators with a single-user application, which constrains them to update the shared terrain from their PCs, using a turn-taking strategy. Moreover, collaborators have to visualize the terrain through 2D views, confusing novice users when conceiving its shape in 3D. In this article, we describe an architecture for collaborative applications, which allow co-located users to sketch a terrain using their mobile devices concurrently. Two interaction modes are supplied: the standard one and an augmented reality-based mode, which helps collaborators understand the 3D terrain shape. Using the painting with brushesparadigm, users can modify the terrain while visualizing its shape evolution through the camera of their devices. Work coordination is promoted by enriching the 3D space with each collaborator's avatar, which provides awareness information about identity, location, and current action. We implemented a collaborative application from this architecture that was tested by groups of users, who assessed its hedonic and pragmatic qualities in both interaction modes and compared them with the qualities of a similar Web terrain editor. The results showed that the augmented reality mode of our prototype was considered more attractive and usable by the participants.

Análise dos sintomas osteomioarticulares pelo uso de tecnologias portáteis em docentes de uma instituição privada / Analysis of musculoskeletal symptoms by the use of portable technologies in teachers of a private institution

As tecnologias portáteis cada vez mais estão sendo utilizadas e tornaram-se necessárias para o dia a dia da população de maneira geral, entretanto, o uso em excesso, más posturas durante o uso, padrão inadequado ergonômico, potencializado pelo sedentarismo, estresse, expõem seus usuários a riscos de desenvolver processos agudos e crônicos de dor e possíveis lesões osteomioarticulares. Objetivo: Analisar a prevalência dos sintomas osteomioarticulares pelo uso de tecnologias portáteis em docentes de uma instituição privada. Materiais e métodos: Trata-se de um estudo descritivo e observacional transversal, de caráter quantitativo, composta por uma amostra de 68 docentes do centro de ciências biológicas e da saúde na Universidade da Amazônia. As variáveis encontradas foram mensuradas e tabuladas visando eliminar erros utilizando o software microsoft excel, assim como, foram feitas análises descritas dos dados através do software bioestat. Resultados: Como resultados, foi constatado que docentes de uma instituição privada apresentam em grande maioria sintomas osteomioarticulares pelo uso de tecnologias portáteis, principalmente para a região cervical (49% dos participantes), seguido da região lombar (46% dos participantes) obtendo valores significantes para esses e demais achados(p<0,05). Conclusão: Os resultados deste estudo apresentam importância sobre vários segmentos, principalmente para os docentes, pois fornece fundamentais informações e descrições acerca do uso de tecnologias portáteis e possíveis repercussões no sistema osteomioarticular.
