RESUMO

Background: Digital inclusion of older people is an important agenda for the future and well-being of the older population, as it represents a form of social inclusion with significant gains for healthy aging. The present study aimed to understand the experiences of Brazilian older adults who use smartphones and the implications in their daily lives. Method: A qualitative study was developed using a constructivist grounded approach. Older people (≥60 years) with prior access to a smartphone were invited to participate in the study. Participation took place through semi-structured, audio-recorded interviews. Data collection and analysis occurred simultaneously using a constant comparative approach. Data management and analysis used the Atlas.ti® software. Results: Overall, 37 older people participated, with an average age of 70.60 ± 6.95 years, predominantly female (n = 33), white (n = 25), married (n = 26) and retired (n = 27). The first sample group included 27 older people with family support and the second group included 10 older people without family support (who lived alone in their homes). A core category emerged from the data analysis-"Expanding the personal and social development of older adults through smartphone communication"-around which three main categories emerged: 1) The smartphone as "a window to the world"; 2) The problem of misinformation and fake news on virtual networks; 3) Technological paradoxes in the use of smartphones. Conclusions: The digital transition associated with smartphone use brings unimaginable benefits to older adults who adopt positive habits to improve their well-being and expand their social connections, following efforts proposed by the Decade of Healthy Aging. However, older adults still face disparities and experience a significant digital divide, which represents a major challenge. Barriers to access are further aggravated in developing countries. We hope this study contributes to public health policies on digital inclusion and healthy aging.

RESUMO

This study evaluates the performance of large intelligent surface (LIS) technology in the context of a multi-user MIMO mobile communication system (Mu-MIMO) proposed for the sixth generation (6G). LIS employs digitally controlled reflectors to enhance Signal-to-Interference plus Noise Ratio (SINR) and establish line of sight (LoS) connectivity in non-LoS environments, improving transmission security. Analytical expressions are derived to assess LIS performance metrics, including distribution parameters, bit error probability, and secrecy outage probability, considering the presence of eavesdroppers and environmental fading. The study highlights the potential of LIS technology to enhance the confidentiality and reliability of digital communication systems in next-generation networks.

RESUMO

The BRICS countries-Brazil, Russia, India, China, and South Africa-are committed to achieving United Nations Sustainable Development Goal 13, which focuses on mitigating climate change. To attain this goal, it is crucial to emphasize the significance of ICT, renewable energy sources, industrialization, and institutional quality. This study contributes to the literature by examining the potential role of these factors in environmental sustainability in the BRICS economies from 2000 to 2021, utilizing cross-sectional augmented autoregressive distributed lag (CS-ARDL) estimation and other novel econometric techniques. Accordingly, the study suggests that BRICS governments and policymakers prioritize the use of ICT in the industrial and institutional sectors to achieve faster environmental sustainability in the short-run, as per the CS-ARDL results. However, the study advises caution in the long-term as the interaction between ICT and renewable energy sources, industrialization, and institutional quality may not favour environmental quality. Although the renewable energy sources interaction with ICT may not yield immediate progress, strong measures need to be taken to ensure that short-term gains are not nullified. In conclusion, the study highlights the potential of ICT, renewable energy sources, industrialization, and institutional quality in achieving environmental sustainability in the BRICS countries, while recommending cautious measures in the long run to safeguard the progress made.

RESUMO

BACKGROUND: Although comprehensive lifestyle habits are crucial for healthy aging, their adherence tends to decline as individuals grow older. Sustaining a healthy life over time poses a motivational challenge. Some digital tools, such as smartphone apps aimed at promoting healthy habits, have been used to counteract this decline. However, a more profound investigation is necessary into the diverse experiences of users, particularly when it concerns older adults or those who are unfamiliar with information and communications technologies. OBJECTIVE: We aimed to develop a mobile app focused on promoting the health of older adults based on the principles of software engineering and a user-centered design. The project respected all ethical guidelines and involved the participation of older adults at various stages of the development of the app. METHODS: This study used a mixed methods approach, combining both quantitative and qualitative methodologies for data collection. The study was conducted in Ribeirão Prêto, São Paulo, Brazil, and involved 20 older adults of both genders who were aged ≥60 years and enrolled in the Physical Education Program for the Elderly at the University of São Paulo. The research unfolded in multiple phases, encompassing the development and refinement of the app with active engagement from the participants. RESULTS: A total of 20 participants used a mobile health app with an average age of 64.8 (SD 2.7) years. Most participants had a high school education, middle-class status, and varying health literacy (mean score 73.55, SD 26.70). Overall, 90% (18/20) of the participants owned smartphones. However, 20% (4/20) of the participants faced installation challenges and 30% (6/20) struggled with web-based searches. The focus groups assessed app usability and satisfaction. Adjustments increased satisfaction scores significantly (Suitability Assessment of Materials: 34.89% to 70.65%; System Usability Scale: 71.23 to 87.14). Participant feedback emphasized font size, navigation, visual feedback, and personalization, and suggestions included health device integration, social interaction, and in-app communication support. CONCLUSIONS: This study contributes to the development of health care technologies tailored to the older adult population, considering their specific needs. It is anticipated that the resulting app will serve as a valuable tool for promoting healthy habits and enhancing the quality of life for older adults.

RESUMO

Este estudo de abordagem qualitativa teve como objetivo analisar, a partir do referencial teórico da Análise Institucional, as informações sobre cuidados paliativos veiculadas nos programas da Rede Globo de televisão. A partir da busca no site Globoplay, foram identificados trinta vídeos relacionados ao assunto entre os anos de 2013 e 2020. Entre outros aspectos, foi observado o predomínio de informações divulgadas no mês de outubro, em programas locais da região sudoeste e presença dos profissionais de saúde como a principal fonte de consulta. A televisão se mostrou um importante dispositivo de divulgação de informações sobre cuidados paliativos com os mais variados sentidos, a saber: espiritualidade, alívio da dor e protagonismo dos sujeitos e seus familiares na busca por um processo de morrer com qualidade. Entretanto, nenhum vídeo citou o Sistema Único de Saúde (SUS), o que demonstrou sua invisibilidade nesse meio. Recomenda-se que os meios de comunicação acelerem a divulgação do assunto e que enfatizem o SUS nos conteúdos divulgados.

This qualitative study analyzes the information on palliative care broadcasted by Rede Globo de Televisão's programs based on the theoretical framework of Institutional Analysis. A search on the "Globoplay" website retrieved 30 videos related to the subject between 2013 and 2020. Among other aspects, information was mainly broadcasted in the month of October and in local southwestern programs, having health professionals presented as their main source of information. Television proved to be an important device for disseminating information on palliative care aspects such as spirituality, pain relief and the role of patients and their families in the search for a quality dying process. However, no video mentioned the Unified Health System (SUS), showing its media invisibility. Media conglomerates should increase the dissemination of palliative care information, emphasizing the role played by the SUS.

RESUMO

In the face of declining vaccination coverage and the dissemination of health-related information, conversations in the public/mediatic digital sphere constitute a relevant study area for the field of health communication. Through a qualitative study based on the analysis of government publications, digital press, and social media, we characterize the public conversation on vaccines - in terms of topics, moments, axes, and framings in Argentina during the 2020-2021 period - marked by the debate on covid-19 vaccines. The results show that public conversation focused on covid-19 vaccination, structured in two distinct moments (vaccine production and vaccination campaign), and under moral framings grounded in vaccination as a care practice and science as an authoritative voice. Simultaneously, doubts about the safety and efficacy of vaccines shaped arguments of vaccine hesitancy, which we understand as part of extended practices associated with distrust towards institutions and reinterpretations of scientific knowledge and care.

Ante la caída de las coberturas vacunales y la circulación informativa sobre salud, las conversaciones en el entorno público/mediático digital constituyen un ámbito de estudio relevante para el campo de la comunicación en salud. A través de un estudio cualitativo, basado en el análisis de publicaciones del gobierno, la prensa digital y las redes sociales, caracterizamos la conversación pública sobre vacunas ­en términos de temas, momentos, ejes y encuadres en Argentina en el período 2020-2021­ signada por el debate sobre las vacunas covid-19. Los resultados muestran que la conversación pública se centralizó en la vacunación contra el covid-19, se estructuró en dos momentos diferenciados (producción de vacunas y campaña de vacunación) y bajo encuadres morales sustentados en la vacunación como práctica de cuidado y la ciencia como voz autorizada. En simultáneo, las dudas sobre la seguridad y eficacia de las vacunas estructuraron argumentos de reticencia vacunal, que entendemos como parte de prácticas extendidas, asociadas con las desconfianzas hacia las instituciones y reinterpretaciones del conocimiento científico y del cuidado.

RESUMO

ABSTRACT Objective This survey aims atreviewing the journalistic narratives of the newspaper Folha de São Paulo (digital edition) about hunger in Brazil during the 2020 pandemic period. It is known that journalism plays an important role in keeping the public informed and in helping to contribute to the shaping of society's opinion. Despite hunger being a structural phenomenon in this country, little is published in the mainstream media discussing the magnitude of the problem and the articulation of measures taken in the three government spheres (federal, state and municipal), to ensure access to food to the most vulnerable populations. Method News excerpts addressing hunger as the main topic were selected from Folha de São Paulo daily newspaper and were highlighted based on reading keys (n=11, published between March and December 2020). Results In all the selected articles, the newspaper addressed the cause of hunger from the perspective of the pandemic (passing event and manifestation). Issues linked to the economic and social crisis experienced in the country were not emphasized. This form of covering hunger in news articles can enhance the idea that the poor are the result of the currently spreading fatality. Conclusion Finally, from these first results we could infer that the newspaper, when addressing hunger in Brazil in the first months of the COVID-19 pandemic, sought to construct a biased reality that hunger was derived from the health crisis, at the same time that it presents the hungry people narratives as a discursive strategy to sensitize the reader to Folha de São Paulo intentions.

RESUMO Objetivo A nota tem como objetivo examinar as narrativas jornalísticas do jornal Folha de São Paulo (digital) sobre a fome no Brasil, no período pandêmico de 2020, uma vez que se compreende que as narrativas jornalísticas têm um papel importante na formação de opinião da sociedade. Apesar da fome ser um fenômeno estrutural no país, pouco se vê nos grandes meios de comunicação o debate sobre a magnitude dos problemas e articulação de medidas governamentais nas três esferas de gestão (federal, estadual e municipal), que possam assegurar o acesso à alimentação adequada e saudável dos mais vulneráveis. Método Foram selecionadas notícias na Folha de São Paulo que tratavam da fome como pauta principal, sendo analisadas com base em chaves de leitura (n=11, divulgadas entre março e dezembro de 2020). Resultados Em todas as matérias selecionadas o jornal abordou a causa da fome a partir da perspectiva da pandemia (acontecimento e manifestação passageira). As questões vinculadas à crise econômica e social vivenciada no país não foram enfatizadas. A forma de acionar os famintos nas matérias pode reforçar a ideia de que os pobres são fruto da fatalidade que se propaga. Conclusão Por fim, os resultados iniciais permitem inferir que o jornal ao editar a fome no Brasil, no primeiro ano da pandemia de COVID-19, procurou construir uma realidade enviesada de que a fome é derivada de uma crise sanitária ao mesmo tempo que apresenta as narrativas dos famintos como estratégia discursiva para sensibilizar o leitor em relação às suas intenções.

RESUMO

Objetivos: identificar e descrever as notícias sobre erros de medicação ocorridos no Brasil e divulgados na mídia digital brasileira. Metodológia: pesquisa de caráter exploratório, com dados coletados em notícias de mídias digitais do Brasil entre 2015 e 2019. A busca das notícias sobre erros de medicação foi realizada no Google®. Os casos divulgados na mídia foram descritos conforme o tipo e a classificação do erro, medicamento e profissional envolvido na ocorrência do erro, características do paciente que sofreu o erro e local onde o erro ocorreu. Resultados: dos 20 erros noticiados identificados na busca, foram encontrados 11 casos de erros com morte (55,0%), seis casos de erros com dano (30,0%) e três casos de erros sem danos (15,0%). Dos 23 pacientes envolvidos nos erros, 14 pertenciam a grupos de extremos etários, sendo nove pacientes pediátricos (39,1%) e cinco pacientes geriátricos (21,8%). Quanto ao tipo de erro, quatro casos noticiados envolvendo erros de prescrição (20,0%), cinco reportando erros de dispensação (25,0%), 10 erros de administração (50,0%), e um envolvendo erro de dispensação e administração concomitantemente (5,0%). Dentre os 11 casos de erros com morte do paciente, oito traziam a informação sobre qual medicamento estava envolvido no erro, sendo seis deles considerados medicamentos potencialmente perigosos (MPP). Conclusão: os resultados do presente estudo apontam para a necessidade de implementação de melhorias nos estabelecimentos de saúde em geral ­ farmácias, drogarias, hospitais, centros de saúde ­ no que tange a prevenção de erros de medicação. Para isso, devem ser priorizadas iniciativas envolvendo os sistemas de medicação com elevada efetividade, sobretudo em contextos de situações de alto risco como uso de MPP e cuidado a pacientes em extremos etários

Aims: to identify and describe the news about medication errors that occurred in Brazil and were published in the Brazilian digital media. Methods: exploratory research, with data collected in news from digital media in Brazil, between 2015 and 2019. The search for news about medication errors was carried out on Google®. The cases published in the media were described according to the type and classification of the error, medication and professional involved in the occurrence of the error, characteristics of the patient who suffered the error and place where the error occurred. Results: of the 20 reported errors identified in the search, 11 cases of errors with death (55.0%), six cases of errors with harm (30.0%) and three cases of errors without harm (15.0%) were found. Of the 23 patients involved in the errors, 14 belonged to extreme age groups, nine pediatric patients (39.1%) and five geriatric patients (21.8%). As for the type of error, four reported cases involving prescription errors (20.0%), five reporting dispensing errors (25.0%), 10, administration errors (50.0%) and one involving concurrent dispensing and administration error (5.0%). Among the 11 cases of errors resulting in patient death, eight contained information about which medication was involved in the error, six of which were considered high alert medications. Conclusions: the results of this study point to the need to implement improvements in health institutions in general - pharmacies, drugstores, hospitals, health centers - with regard to the prevention of medication errors. For this, initiatives involving medication systems with high effectiveness should be prioritized, especially in contexts of high-risk situations such as the use of high alert medications and care for patients at extremes of age

RESUMO

A fim de conhecer o tempo e a frequência com que idosos se expõem a notícias e informações sobre a COVID-19 por diferentes mídias e relacioná-los com sintomas depressivos e de ansiedade, 154 idosos (M = 69,06) do Distrito Federal responderam a um questionário online. A amostra foi composta majoritariamente por mulheres, brancas, escolarizadas e com renda proveniente de aposentadoria e/ou pensão. Constatou-se que a televisão foi o meio de comunicação mais utilizado pelos participantes, seguido pelas redes sociais. Ao considerar características demográficas, idosos mais jovens (60 a 74 anos) e com ensino superior completo apresentaram maior exposição a notícias por meio das redes sociais do que os mais velhos e com menor escolaridade. Idosos com rastreio para depressão e transtorno de ansiedade generalizada permaneceram mais horas expostos a informações sobre a COVID-19 veiculadas pela televisão que idosos não rastreados. Além disso, aqueles com rastreio para depressão relataram maior frequência de exposição a esse conteúdo pela televisão e pelas redes sociais. Os resultados deste estudo revelam a necessidade de planejamento de medidas de promoção e prevenção em saúde específicas para a população idosa a fim de lidar com as consequências da pandemia e, especialmente, infodemia de COVID-19(AU)

Para conocer el tiempo y la frecuencia con que los ancianos están expuestos a noticias e informaciones sobre el COVID-19 por diferentes medios de comunicación y relacionarlos con los síntomas depresivos y de ansiedad, 154 ancianos (m = 69,06) del Distrito Federal respondieron a un cuestionario online. La muestra estaba compuesta mayoritariamente por mujeres, de raza blanca, con estudios y con ingresos por jubilación y/o pensión. Se comprobó que la televisión era el medio de comunicación más utilizado por los participantes, seguido de las redes sociales. Teniendo en cuenta las características demográficas, los más jóvenes (60 a 74 años) y con estudios superiores completos presentan una mayor exposición a las noticias a través de las redes sociales que los más mayores y con menor escolaridad. Los ancianos con cribado de depresión y trastorno de ansiedad generalizada permanecieron más horas expuestos a la información sobre COVID-19 emitida por televisión que los ancianos no cribados. Además, los que se sometieron a pruebas de detección de la depresión informaron de una mayor frecuencia de exposición a este contenido por parte de la televisión y los medios sociales. Los resultados de este estudio revelan la necesidad de planificar medidas de promoción de la salud y de prevención específicas para la población de edad avanzada con el fin de hacer frente a las consecuencias de la pandemia y, especialmente, de la infodemia de COVID-19(AU)

In order to know the time and frequency with which elderly are exposed to news and information about COVID-19 through different media and relate them with depressive and anxiety symptoms, 154 elderly (M = 69.06) from Distrito Federal answered an online questionnaire. The sample was composed mostly of women, white, educated, and with income from retirement and/or pension. It was found that television was the media most used by participants, followed by social networks. Considering demographic characteristics, younger elders (60 to 74 years old) and with complete college education had more exposure to news through social networks than the older ones and with less education. Elderly with screening for depression and generalized anxiety disorder remained exposed more hours to information about COVID-19 broadcast on television than unscreened elderly. In addition, those with screening for depression reported greater frequency of exposure to this content on television and social media. The results of this study reveal the need for health promotion and prevention measures planning specific to the elderly population to deal with the consequences of the pandemic and especially infodemic of COVID-19(AU)

RESUMO

This paper examines the performance of orthogonal frequency division multiplexing (OFDM) systems for vehicle-to-vehicle (V2V) communication channels. More specifically, a doubly selective channel under high intercarrier interference (ICI) is considered. Current solutions involve complex detection and/or reduced spectral efficiency receivers. This paper proposes the use of virtual carriers (VC) in an OFDM system with a low-complexity maximal ratio combining (MRC) detector to improve the bit error rate (BER) performance. The results show that VC provides diversity in received data, resulting in a ≥5 dB gain compared to previous OFDM systems with conventional linear/nonlinear detectors used as a reference. The detector presented in this paper has linear complexity, making it a suitable solution for real-time V2V communication systems.

RESUMO

A novel graphene antenna composed of a graphene dipole and four auxiliary graphene sheets oriented at 90∘ to each other is proposed and analyzed. The sheets play the role of reflectors. A detailed group-theoretical analysis of symmetry properties of the discussed antennas has been completed. Through electric field control of the chemical potentials of the graphene elements, the antenna can provide a quasi-omnidirectional diagram, a one- or two-directional beam regime, dynamic control of the beam width and, due to the vertical orientation of the dipole with respect to the base substrate, a 360∘ beam steering in the azimuth plane. An additional graphene layer on the base permits control of the radiation pattern in the θ-direction. Radiation patterns in different working states of the antenna are considered using symmetry arguments. We discuss the antenna parameters such as input reflection coefficient, total efficiency, front-to-back ratio, and gain. An equivalent circuit of the antenna is suggested. The proposed antenna operates at frequencies between 1.75 THz and 2.03 THz. Depending on the active regime defined by the chemical potentials set on the antenna graphene elements, the maximum gain varies from 0.86 to 1.63.

RESUMO

Introduction: Contact investigation is a proven intervention for tuberculosis (TB) case finding and prevention. Although widely endorsed by national public health authorities and the World Health Organization, many countries struggle to implement it effectively. The objective of the study is to describe and characterize the barriers and facilitators of TB contact investigation in Cali, Colombia from the perspective and experience of the key stakeholders involved. Methods: We collected data from group discussions during two workshop sessions with clinic and public health staff involved in TB contact investigation (June 2019 and March 2020 respectively) and semi-structured interviews with TB cases and their household contacts (July 2019 to April 2020). We undertook an inductive thematic analysis with the RADaR technique to characterize the barriers and facilitators of the TB contact investigation process. Results: The two workshops included 21 clinics and 12 public health staff. We also conducted 26 semi-structured interviews with TB cases and their household contacts. Using thematic analysis, we identified four common themes: Healthcare Operations, Essential Knowledge, Time Limitations and Competing Responsibilities, and Interpersonal Interactions. The main barriers to conducting household visits were low data quality, stigma and mistrust, safety concerns for health workers, and limited resources. The main barriers to TB uptake by contacts were competing responsibilities, low TB risk perceptions among contacts, and difficulty accessing diagnostic tests for contacts. In contrast, good communication and social skills among health workers and accurate TB knowledge facilitated successful household visits and TB test uptake, according to key stakeholders. Conclusion: This study provides a deeper understanding of TB contact investigation barriers and facilitators in a high-prevalence urban setting in a middle-income country from the perspective and experience of key stakeholders. The study shed light on the barriers that hinder household contacts engagement and TB test uptake such as issues of systemic capacity and TB knowledge. Also, highlighted facilitators such as the importance of interpersonal communication skills among health workers in the public and private sector. The insights from this study can serve as a valuable resource for public health organizations seeking to enhance their contact investigation efforts and improve TB control in similar settings.

RESUMO

Objetivo. Determinar el cumplimiento a las recomendaciones de la Organización Mundial de la Salud (OMS) de las noticias sobre suicidio emitidas por canales de la televisión peruana. Materiales y métodos. Estudio cuantitativo y descriptivo. La unidad de análisis fueron las noticias de suicidio emitidas por ocho canales de televisión peruana durante los años 2020 y 2021. Las noticias se clasificaron en tres categorías: noticias sobre suicidio, intento de suicidio y prevención del suicidio. Se utilizó un instrumento de evaluación compuesto por las recomendaciones de la OMS. Resultados. Se analizaron un total de 126 noticias. Ninguna de estas noticias cumplió en su totalidad con las recomendaciones de la OMS. Las noticias sobre suicidio o intento de suicidio cumplieron con 4 de 13 recomendaciones, siendo la recomendación más acatada la de evitar publicar notas suicidas (97,4%), mientras que la menos cumplida fue la de instruir a la población sobre el suicidio y su prevención, y no difundir mitos (0,9%). Las noticias de prevención de suicidio cumplieron 5 de 7 recomendaciones. Conclusiones. Las noticias sobre suicidio emitidas en la televisión peruana en los años 2020 y 2021 mostraron un bajo cumplimiento a las recomendaciones de la OMS. Los profesionales de la comunicación tienen un rol fundamental en la prevención del suicidio, limitando la información sensible y difundiendo información de ayuda. Es fundamental el conocimiento de estas recomendaciones por los comunicadores, y el trabajo conjunto entre el equipo periodístico y los profesionales de la salud mental en la comunicación de noticias relacionadas con el suicidio.

Objective. To determine if suicide news reports broadcasted by Peruvian television channels comply with the World Health Organization (WHO) recommendations for reporting suicide news. Materials and methods. Quantitative and descriptive study. The unit of analysis was the suicide news broadcasted by eight Peruvian television channels during the years 2020 and 2021. News were classified into three categories: news about suicide, attempted suicide and suicide prevention. We used an evaluation instrument composed of WHO recommendations. Results. A total of 126 news reports were analyzed; but none of these complied fully with the WHO recommendations. The news reports on suicide or attempted suicide complied with 4 of 13 recommendations. Most reports complied with avoiding to publish suicide notes (97.4%); on the other hand, educating about suicide and its prevention, and not disseminating myths was the recommendation least complied with (0.9%). Suicide prevention news reports complied with 5 of 7 recommendations. Conclusions. Suicide news reports on Peruvian television in 2020 and 2021 showed low compliance with WHO recommendations. Communication professionals have a fundamental role in suicide prevention, limiting sensitive information and disseminating helpful information. It is essential for communicators to be aware of these recommendations and for the journalism team and mental health professionals to work together in the communication of news related to suicide.

Authors recommend to generalize the implementation in the National Health System.

RESUMO

Perfluoroalkyl substances are man-made chemicals with ample consumer and industrial applications. They are widely used and are resistant to environmental and metabolic degradation. Several studies have evaluated the effects of Perfluorohexane sulfonate on reproduction. However, there are few reports exploring the cell and molecular mechanisms of its toxicity in the ovary. The aim of this study was to investigate the effects of PFHxS exposure on the estrous cycle, ovulation rate, and the underlying mechanisms of action in female mice in vivo. The animals received a single sub-lethal dose of PFHxS (25.1 mg/kg, 62.5 mg/kg) or vehicle and were stimulated to obtain immature cumulus cell-oocyte complexes (COCs) from the ovaries, or superovulated to develop mature COCs. To evaluate oocyte physiology, Gap-junction intercellular communication (GJIC) was analyzed in immature COCs and calcium homeostasis was evaluated in mature oocytes. PFHxS exposure prolonged the estrous cycle and decreased ovulation rate in female mice. Connexins, Cx43 and Cx37, were downregulated and GJIC was impaired in immature COCs, providing a possible mechanism for the alterations in the estrous cycle and ovulation. No morphological abnormalities were observed in the mature PFHxS-exposed oocytes, but calcium homeostasis was affected. This effect is probably due, at least partially, to deregulation of the endoplasmic reticulum calcium modulator, Stim1. These mechanisms of ovarian injury could explain the reported correlation among PFHxS levels and subfertility in women undergoing fertility treatments.

RESUMO

Nowadays, there is a broad range of methods for detecting and evaluating executive dysfunction ranging from clinical interview to neuropsychological evaluation. Nevertheless, a critical issue of these assessments is the lack of correspondence of the neuropsychological test's results with real-world functioning. This paper proposes serious games as a new framework to improve the neuropsychological assessment of real-world functioning. We briefly discuss the contribution and limitations of current methods of evaluation of executive dysfunction (paper-and-pencil tests, naturalistic observation methods, and Information and Communications Technologies) to inform on daily life functioning. Then, we analyze what are the limitations of these methods to predict real-world performance: (1) A lack of appropriate instruments to investigate the complexity of real-world functioning, (2) the vast majority of neuropsychological tests assess well-structured tasks, and (3) measurement of behaviors are based on simplistic data collection and statistical analysis. This work shows how serious games offer an opportunity to develop more efficient tools to detect executive dysfunction in everyday life contexts. Serious games provide meaningful narrative stories and virtual or real environments that immerse the user in natural and social environments with social interactions. In those highly interactive game environments, the player needs to adapt his/her behavioral performance to novel and ill-structured tasks which are suited for collecting user interaction evidence. Serious games offer a novel opportunity to develop better tools to improve diagnosis of the executive dysfunction in everyday life contexts. However, more research is still needed to implement serious games in everyday clinical practice.

RESUMO

On-chip wireless communications require optical nanoantennas with dynamically tunable radiation patterns, which may allow for higher integration with multiple nanoantennas instead of two fixed nanoantennas in existing approaches. In this paper, we introduce a concept to enable active manipulation of radiated beam steering using applied magnetic fields. The proposed system consists of a highly directive Yagi-Uda-like arrangement of magnetoplasmonic nanoribs made of Co6Ag94 and immersed in SiO2. Numerical demonstration of the tilting of the radiated beam from the nanoantenna on its plane is provided with full-wave electromagnetic simulations using the finite element method. The tilt direction of the radiated beam can be changed by reversing the magnetization direction, while the conventional plasmonic nanoantenna pattern is recovered by demagnetizing the system. The geometry of the nanoantenna can be tailored to work at optical or infrared wavelengths, but a proof of concept for λ = 700 nm is conducted for taking advantage of the high magneto-optical activity of Co6Ag94. The design was based on experimental data for materials that can be fabricated via nanolithography, thus permitting magnetically on-chip reconfigurable optical wireless communications.
