Pobreza y pobreza extrema en Costa Rica: Una deuda histórica pendiente de resolver
Authors: Ortega Abelino
Published: May 2022

A pesar del reconocimiento histórico que el país ha tenido en materia de consolidación de su democracia, el respeto a los derechos humanos, la fortalecida institucionalidad pública y el sólido Estado social de derecho, durante los últimos años esta condición ha cambiado. El país ha tenido un deterioro significativo en materia de cobertura en servicios de salud, educación, vivienda, trabajo y seguridad social, y a pesar de los diversos esfuerzos por revertirlo, esto no ha sido posible, induciendo al grueso de la población, a un estado de desilusión e incertidumbre que le conduce a la desconfianza en las propuestas de partidos y lideres políticos tradicionales. Considerando los planteamientos emitidos en este artículo y sin pretender una respuesta definitiva, la situación de pobreza podría tener relación directa con el tipo de política social impulsada por los gobiernos de los últimos 40 años, la obsolescencia de la gestión de la institucionalidad del sector social, la imposibilidad de articular una estrategia respetando los espacios de trabajo de cada institución y, el cortoplacismo de los procesos de planificación.
Cancer entertainment education and Netflix – an exploratory study
Authors: Siuda Piotr
Published: May 2022

The entertainment education (EE) approach shows that entertainment storylines influence people’s attitudes, opinions, and behavior, and this occurs, among others, when it comes to health and disease. In the case of TV shows and movies cancer is the most frequently shown disease, and this is especially important when considering the rise of VOD platforms, gaining in subscribers and popularity. The article aims at signaling Netflix’s EE potential, hence it could be a starting point for future studies of streaming platform’s EE, a highly neglected area. Netflix is thus 1) compared with other popular VODs in terms of the number of cancer content (this being the main interest of the presented analysis) and 2) three content categories are indicated. Also, 3) a brief description of selected texts is presented. The aim of the article is exploratory, and it highlights the need for future research, as the potential of Netflix’s EE seems the greatest when compared to other platforms analyzed. Netflix has the largest number of contents featuring cancer, and these could influence audiences, i.e., raise awareness, change attitudes, and motivate individuals to act.

Published: May 2022

This paper predicts a measurement indicator for the trade mispricing channel and its
effectiveness in identifying IFFs. A model, gaussian multivariate anomaly detection algorithm,
for classifying between a legal and illegal transactions that are suspicious in terms of
misreporting was developed. The method is a machine learning technique, and uses data from
South Africa, Botswana, USA, and China over a period from 2000-2019, to learn whether there
is any intriguing differences on the model performance based on these countries and effect of
other factors. Imports, Exports are used as features of the model while the netflow derived from
these features is used as the third feature of the model. Imports and exports data are sourced from
IMF’s Direction of Trade Statistics database. Annual tariffs’ data and corruption data comes
from the WDI database and the Transparency International’s Corruption Perception index,
respectively. Data for ‘accounting and auditing standards’ comes from the world economic
forum. This study contributes to the debate on trade mispricing by proving a baseline
measurement to help detects and track IFFs. The result showed that while the model may be
effective in detecting IFFs due to mispricing, other factors may however contribute to
irregularities of trading data that is flagged as IFFs. This in addition to accounting for total
quantum, also provide details empowering governments with the information to stimulate and
drive the desire to curb IFFs from its different sources and channels.

C-axis texture of high-rate-sputtered Nd2Fe14B thin films: independence of sheet texture of Mo underlayer
Authors: Tsuchida Takayuki , Fukushima Jun , Saito Shin , Hayashi Yamato , Takizawa Hirotsugu
Published: May 2022

In this study, we investigated the effects of the sheet texture of the Mo underlayer on the c-axis texture of the high-rate-sputtered Nd2Fe14B phase. The magnetic properties revealed that the squareness of the Nd–Fe–B magnetic layer did not depend on the sheet texture of the Mo underlayer but on the substrate temperature: large squareness was obtained when the magnetic layer was sputtered at high substrate temperature above 500 °C. In-plane X-ray diffraction measurements indicated that the intensity of diffraction from the Nd2Fe14B (410) plane did not depend on the sheet texture of the Mo underlayer but on the substrate temperature: high intensity was obtained when the magnetic layer was sputtered at above 500 °C, which was consistent with magnetic properties. These results support that the c-axis texture of the high-rate-sputtered magnetic layer was driven by the c plane with the lowest surface energy among the crystal planes in the Nd2Fe14B phase.
Tunable mid-infrared ultra-narrowband plasmonic absorber and sensor based on bulk Dirac semimetal metamaterials
Authors: Wang Chen-Hao , Huang Kai , Ma Rui , Liu Gui-Dong , Wang Ling-Ling , Lin Qi
Published: May 2022

We propose a tunable mid-infrared ultra-narrowband plasmonic absorber and sensor based on bulk Dirac semimetal metamaterials, which is hypersensitive to the varation of background refractive index. Based on the tunable characteristic of bulk Dirac semimetal, the absorption wavelength can be dynamically adjusted without re-optimizing the geometric parameters, meanwhile, perfect absorption can be maintained despite the equal scale variation of the structure. The absorption bandwidth is so tiny that the sensitivity and figure of merit can be up to 16 000 nm RIU−1 and 3500 RIU−1, respectively. Our results may open up new avenues for the design of optical filter and bio-chemical sensing.

Published: May 2022

Nursing students are trained to promote healthy practices among clients but it does not necessarily mean that they are applying it to themselves. As healthcare providers, nursing students offer support to clients in the promotion of healthy lifestyle. However, there is limited literature exploring the types of social support that nursing students have and its relationship to personal health practices. The purpose of this study was to determine personal health practices among nursing students and its relationship to social support. This cross-sectional study was conducted on 163 nursing students from two universities in Cavite and Pasay and selected using purposive sampling. They answered self-report questionnaires including the perceived social support scale and personal health practices. Data were analyzed by statistical tests of Spearman Rank correlation coefficient. The results revealed a high level of social support with a mean of 3.78(SD = 0.62) and moderate personal health practices with a mean of 3.15 (SD = 0.31). Although there is no significant relationship between the general perceived social support and personal health practices, emotional support showed a positive relationship with personal health practices (p = 0.004). Students’ score in health practices does not differ significantly considering gender, but significant differences are found when age is considered (p = 0.01).

Short-Circuit Calculation of Islanded AC Microgrids with Virtual Impedance Current Limiters
Authors: Pompodakis Evangelos
Published: May 2022

In this manuscript, a novel Δ-circuit approach is
proposed, which enables the fast calculation of fault currents in
large islanded AC microgrids (MGs), supplied by inverter-based
distributed generators (IBDGs) with virtual impedance current
limiters (VICLs). The concept of virtual impedance for limiting
the fault current of IBDGs has gained the interest of research
community in the recent years, due to the strong advantages it
offers. Moreover, Δ-circuit is an efficient approach, which has
been widely applied in the past, for the calculation of short?circuit currents of transmission and distribution networks.
However, the traditional Δ-circuit, in its current form, is not
applicable in islanded MGs, due to the particular characteristics
of such networks, e.g., the absence of a slack bus. To overcome
this issue, a novel Δ-circuit approach is proposed in this paper,
with the following distinct features: a) precise simulation of
islanded MGs, b) fast computational performance, c) generic
applicability in all types of faults e.g., single-line, 2-line or 3-line
faults, d) simple extension to other DG current limiting modes,
e.g., latched limit strategy etc. The proposed approach is
validated through the time-domain software of Matlab Simulink,
in a 9-bus and 13-bus islanded MG. The computational
performance of the proposed fault analysis method is further
tested in a modified islanded version of the IEEE 8500-node
network.

Published: May 2022

Non-orthogonal multiple access (NOMA) and ambient backscatter communication (AmBC) play major roles to enhance spectrum efficiency in wireless communication systems. Besides, the AmBC provides good reinforcement for the current trend toward dispensing batteries for battery-free Internet-of-Things (IoT) devices. In this paper, we propose a symbiotic battery-free IoT system, that exploits the downlink transmission of a NOMA multiplexing enabled cellular network, to permit an IoT spectrum-efficient uplink communication. The IoT backscatter device (BD) performs a symbiotic radio (SR) relation with the cellular source to power its communication by intelligently reflecting the received power. We derive a closed-form expression of the ergodic capacity (EC) of the BD transmission and tight approximations of the ECs of the cellular source transmission, where all channels undergo Nakagami-m fading. Additionally, we validate the analytical results obtained using Monte-Carlo simulations. The influences of several system parameters such as power allocation factor, reflection coefficient, and channels’ severity factors have been investigated. Finally, the performance of the proposed system is compared with a benchmark OMA-based system to highlight the achievable performance improvement.

New algorithms for sparse multichannel blind deconvolution
Authors: Nose Filho Kenji , Lopes Renato , Brotto Renan , Senna Thonia , Romano João
Published: May 2022

In this paper we present three new algorithms for sparse multichannel blind deconvolution. The first algorithm is based on a cascade of a forward and a backward prediction error filter. The second consists in an alternating minimization algorithm for estimating both the reflectivity series and the seismic wavelet. The last one is a regularized version of the so called Euclid deconvolution, solved by the well known fast iterative shrinkage-thresholding algorithm (FISTA). Simulation results illustrate that the three algorithms presents some quite interesting results in both synthetic and real data.
Interpretable Neural Networks for Video Separation: Deep Unfolding RPCA with Foreground Masking
Authors: Joukovsky Boris , Eldar Yonina C. , Deligiannis Nikos
Published: May 2022

This paper presents two deep unfolding neural networks for the simultaneous tasks of background subtraction and foreground detection in video. Unlike conventional neural networks based on deep feature extraction, we incorporate domain-knowledge models by considering a masked variation of the robust principal component analysis problem (RPCA). With this approach, we separate video clips into low-rank and sparse components, respectively corresponding to the backgrounds and foreground masks indicating the presence of moving objects. Our models, coined ROMAN-S and ROMAN-R, map the iterations of two alternating direction of multipliers methods (ADMM) to trainable convolutional layers, and the proximal operators are mapped to non-linear activation functions with trainable thresholds. This approach leads to lightweight networks with enhanced interpretability that can be trained on few data. In ROMAN-S, the correlation in time of successive binary masks is controlled with a side-information scheme based on L1-L1 minimization. ROMAN-R enhances the foreground detection by learning a dictionary of atoms to represent the moving foreground in a high-dimensional feature space and by using reweighted-L1-L1 minimization. Experiments are conducted on both synthetic and real video datasets, for which we also include an analysis of the generalization to unseen clips. Comparisons are made with existing deep unfolding RPCA neural networks, which do not use a mask formulation for the foreground. The models are also compared to a 3D U-Net baseline. Results show that our proposed models outperform other deep unfolding models, as well as the untrained optimization algorithms. ROMAN-R, in particular, is competitive with the U-Net baseline for foreground detection, with the additional advantage of providing video backgrounds and requiring substantially fewer training parameters and smaller training sets.
Multimodal Semantic Consistency-Based Fusion Architecture Search for Land Cover Classification
Authors: li xiao
Published: May 2022

Multimodal Land Cover Classification (MLCC) using the optical and Synthetic Aperture Radar (SAR) modalities has resulted in outstanding performances over using only unimodal data duo to their complementary information on land properties. Previous multimodal deep learning (MDL) methods have relied on handcrafted multi-branch convolutional neural networks (CNN) to extract the features of different modalities and merged them for land cover classification. However, natural images-oriented handcrafted CNN models may not the optimal strategies to handle Remote Sensing (RS) image interpretation problems, duo to the huge difference in terms of imaging angles and imaging ways. Furthermore, few MDL methods have analyzed optimal combinations of hierarchical features from different modalities. In this article, we propose an efficient multimodal architecture search framework, namely Multimodal Semantic Consistency-Based Fusion Architecture Search (M2SC-FAS) in continuous search space with the gradient-based optimization method, which can not only discover optimal optical- and SAR-specific architectures according to the different characteristics of the optical and SAR images, respectively, but also realizes the search of optimal multimodal dense fusion architecture. Specifically, the semantic-consistency constraint is introduced to guarantee dense fusion between hierarchical optical and SAR features with high semantic consistency and then capture the complementary performance on land properties. Finally, the basis of curriculum learning strategy is adopted on the M2SC-FAS. Extensive experiments show superior performances of our work on three broad co-registered optical and SAR datasets.
LTE Handover Analysis and Optimization Using a Simulation Platform
Authors: Nayak Sachin
Published: May 2022

Network simulator (ns-3) is a reputed simulation platform for performance evaluation of cellular networks. In this work, we explore use of ns-3 for tracking of successful handovers (HO) and handover failures and consequent impact on 4G LTE network throughput. As cell sizes in networks scale down with each new generation, the increasing number of handovers and handover failures have significant impact. We begin by reviewing analytical models in the literature that aim to predict number of HO and HO failures in terms of HO control and network parameters. We initially conduct a suite of exhaustive validation studies of such analytical models, based on the simulation execution manager (SEM) for ns-3 for parallelization. Via this, we discover new causal relations relating HO failures and choice of HO control parameters on network throughput. Based on these initial results, we next evaluate the application of Gaussian process regression for prediction of instantaneous network throughput and bandit algorithms as an effective mechanism to optimize throughput over time.
Comparative Non-Linear Flux Matrices and Thermal Losses in BLDC with Different Pole Pairs
Authors: Bansal Abhishek
Published: May 2022

In this paper, brushless DC motors are evaluated for nonlinear flux-linkages and thermal losses in the windings and rotor, which causes additional voltage drop and can lead to very dangerous symmetrical three phase line-line-line (LLL) short-circuit. In the paper, it is shown that if the motor does not have appropriate cooling mechanism or other protectionary switchgear, the temperatures in 8-pole (or higher poles) motor with continuous load reaches 1000◦ C, which is nearer to the melting point of copper winding. Thirteen BLDC motors with pole pairs varying from 1 to 13 are studied for comparison for the simulation of thermal losses. The resulting eleven outputs namely rotor angle matrices, flux linkages matrices, flux linkage partial derivatives with respect to current vector, rotor angle, per phase current, each phase winding temperatures, rotor temperature, have been collected as datasets. On knowing the estimated increase in temperature, manufacturers can decide appropriate insulation, cooling mechanism and other motor protectionary circuits.
A Deep Transfer Learning Approach on Identifying Glitch Wave-form in Gravitational Wave Data
Authors: Mesuga Reymond , Bayanay Brian James
Published: May 2022

LIGO is considered the most sensitive and complicated gravitational experiment ever built. Its main objective is to detect the gravitational wave from the strongest events in the universe by observing if the length of its 4-kilometer arms change by a distance 10,000 times smaller than the diameter of a proton. Due to its sensitivity, LIGO is prone to the disturbance of external noises which affects the data being collected to detect the gravitational wave. These noises are commonly called by the LIGO community as glitches. This study focuses on identifying those glicthes using different deep transfer learning algorithms. The extensive experiment shows that algorithm with architecture VGG19 recorded the highest AUC-ROC among other experimented architectures with 0.9898. On the other hand, ResNet152 recorded the lowest AUC-ROC of 0.93954 which performs poorly in identifying almost half of the classes in the Gravity Spy dataset. It was also observed that less complex algorithm like VGG19, DenseNet169 and VGG16 performs better than most of the more complex algorithms featured in this study which could possibly indicate that less complex models might be preferred when identifying glitch wave-forms.
Prolusione
Authors: Muzzarelli Maria Giuseppina
Published: May 2022

Divided into ten points, this paper aims to illustrate how fashion produced modernity, understood as valuing the present, especially its progressive and evolving elements. A process that focused on amplifying “personal visibility”, and in which the abilities of tailors played a crucial role. The effects on the economy of “modern” fashion, born in the Middle Ages, have been significant. Since the thirteenth century, treatisers and preachers, as well as legislators, focused on the way people dressed as a means to regulate society, while artisanal shops invented, ever so often, new objects and prepared unseen social and political scenarios. For all these and many other reasons, we can state that fashion moved and was a metaphor of modernity.
Re-fashioning Industrial Revolution. Fibres, fashion and technical innovation in British cotton textiles, 1600-1780
Authors: Styles John
Published: May 2022

The early years of the British Industrial Revolution were dominated by mechanical innovations in cotton spinning. They emerged at a time when raw cotton prices were unprecedentedly high and the supply of all-cotton fabrics from India, the world’s principal producer of cotton textiles, had contracted dramatically. Most «cotton» textiles manufactured in Britain in the mid-18th century were combinations of expensive cotton yarn and cheap linen yarn. Faced with rising material costs, manufacturers economised by increasing the proportion of cheaper linen yarn. The most fashionable cotton products were, however, made entirely from cotton, or required a fixed proportion of cotton yarn. As the cost of cotton rose, their rapidly rising sales provided the principal inducement to improve quality and cut costs by inventing machines for spinning cotton yarn.
The impact of technological change on medieval fashion
Authors: Wilson Laurel Ann
Published: May 2022

In the early fourteenth century, a new fashion system appeared in Europe, one which was based on constant change and the privileging of the new. This paper argues that the new system did not appear simply as a response to consumer demand; it was also precipitated in part by two major technological innovations: the thirteenth-century development of the advanced broadloom, and the new tailoring techniques of the early fourteenth century. These technological innovations thus helped to precipitate the fashion revolution in obvious material ways, but they also led less directly to social and economic changes which were equally important to the development of fashion.
Keeping up appearances in early modern Castile
Authors: García Fernández Máximo
Published: May 2022

Social emulation stimulated the demand for clothing with the rapid generalisation of certain types of dress in given social circles. Beginning with this birth of fashion in the 16th century, the 18th century witnessed a revolution in consumption. Material culture had a public projection, and appearance and luxury became variables of civilization. In this methodological framework, and using tutorship accounts and inventories (from the Renaissance and Enlightened periods, and from rural and courtesan contexts), this paper aims to examine cloths and accessories that made a difference, with consideration to age, and gender. The evolution of this process in Castile is compared with that in other western European countries in terms of innovation, availability, intercultural contacts and social aspirations.

Published: May 2022

This article compares social learning outcomes of homeschooled and traditionally schooled children under the Accelerated Christian Education Curriculum (ACE). The comparison is done by looking at the social skills constructs of persistence, self–control and social competences. This study adopted the comparative research design, targeting children under the Accelerated Christian Education. 426 children were sampled, with 272 participating Questionnaires were used to collect data on the three constructs. From the computation of children Independent sample t-test, it was revealed that there were no significant differences between the homeschooled and traditionally schooled children as perceived by the children, parents and teachers on the three Social constructs. Consequently it was noted children, parents and teachers received home schooling as effective in developing children persistence, self-control and social competence learning outcomes. It was also demonstrated that acquiring these social skills was independent of home and traditional schooling. Hence it meant home school was equally effective in nurturing the social skills required for children to fit well in society. Though further studies needed to be done to test the robustness of these findings when other variable are added to the model.

This article focuses on the research of the characteristics of foreign energy discourse from the perspective of "One Belt One Road". Combined with the current international economic background, the international energy cooperation language discourse and activities relevant documents reading are carried out through a horizontal and vertical comparative analysis. It is mainly about the language itself to analyze energy discourse development, existing problems and improvement measures. From the case analysis of scientific knowledge competition and discourse construction in the international energy field, it can be seen that adding the scientific and technological discourse perspective to study energy transition is conducive to a deeper understanding of the future energy strategic pattern and direction. It is also advantageous to the huge driving force contained in energy transition to promote China's development and international system change. It requires us to consider the international background work understanding and the language plan itself. We are supposed to analyze the current political hotspots reasonably such as the situation in Russia, Ukraine and related energy development strategies, and conduct in-depth exploration of energy academic discourse studies socially and contemporarily. Besides, it is significant to highlight the times development theme to promote global energy governance.

Two Countries, One Goal: A Mixed-Methods Study of the Development of Study Abroad Sojourners’ Cultural Identification in Japan and Korea
Authors: Lee Jeongyi , Negrelli Kathryn
Published: May 2022

The number of students expanding their academic programs to include learning experiences abroad had been, prior to the recent outbreak of the Coronavirus, steadily increasing over the past two decades. This mixed-method study investigates the cultural identification of short-term study abroad participants and its influence on their acculturation process. Quantitative data from a widely-used acculturation scale were collected from participants before and after the program. In addition, qualitative data from participants’ journals were examined, elucidating the role the study abroad experience played in their cultural identification. This investigation revealed statistically significant effects of cultural experiences on cultural identification, specifically decreases in cultural identification scores. This study supports the concept of cultural identification as a continuum rather than as a dichotomy. Implications suggest that a deeper understanding of students’ cultural identifications can be helpful in developing study abroad programs that promote the goals of student awareness, cultural sensitivity, and global competence.

Published: May 2022

O conceito de cuidados paliativos tem enfatizado a pessoa doente, incluindo suas necessidades especiais e de sua famí­lia, e não mais somente o órgão comprometido, a idade ou o tipo de doença em questão. Feridas constituem um grande problema no final da vida, afetando quase um terço dos pacientes em cuidados paliativos, fato agravado pelas dificuldades em seu manejo devido ao desconforto do paciente e í  natureza geralmente complexa dessas lesões. Sendo assim, o objetivo do presente trabalho foi relacionar os principais tipos de feridas presentes no contexto dos cuidados paliativos, de modo a contribuir com a compreensão deste cenário e com a identificação e desenvolvimento de medidas adequadas para o seu manejo. Trata-se de uma revisão narrativa da literatura que abrangeu o perí­odo compreendido entre 1998 e 2018. Foram utilizadas as bases LILACS, SCIELO e PUBMED, empregando-se os descritores em saúde "cicatrização de feridas" e "cuidados paliativos", posteriormente complementados especificamente para cada lesão. Os resultados foram agrupados e apresentados conforme mecanismos e caracterí­sticas de cada tipo de lesão, destacando-se lesões por pressão, suspeita de lesão tecidual profunda e feridas neoplásicas, entre outras. As informações apresentadas neste trabalho relevaram-se úteis para a melhor compreensão do cenário que envolve feridas em cuidados paliativos, assim como sua identificação, diferenciação e manejo, conforme caracterí­sticas, limitações e necessidades especí­ficas.

Introdução: Verificar, através de uma revisão integrativa, as técnicas de prevenção de lesões por pressão (LPP) em pacientes hospitalizados em unidade de terapia intensiva (UTI). O objetivo do presente estudo foi analisar diferentes formas de prevenção das lesões por pressão em pacientes complexos, como forma de promover o aumento da qualidade de vida. Métodos: Foram analisados estudos publicados entre 2014 e 2019, tendo como referência a base de dados Medline via Pubmed, sendo utilizado na construção da frase de pesquisa o MeSH. Foram estabelecidos os seguintes critérios de inclusão: ensaios clí­nicos controlados e randomizados (ECCR) realizados em humanos, na lí­ngua inglesa e disponí­vel na í­ntegra. E os estudos realizados fora do ambiente hospitalar foram utilizados como critério de exclusão. Para a seleção dos estudos foram utilizadas as variáveis: o tempo de tratamento, o resultado da intervenção e o risco de desenvolvimento de úlceras por pressão em pacientes em UTI. Resultados: Foram identificados 359 estudos envolvendo a prevenção de lesão por pressão. Entretanto, a partir da seleção dos critérios de inclusão e exclusão, somente 25 estudos se integram no propósito dessa revisão. Destes, apenas três foram escolhidos. Conclusão: Esta revisão mostra os efeitos da prevenção de LPP"™s em pacientes hospitalizados em estado crí­tico. Não obstante, a utilização da viragem a cada 2 horas apresenta menor significância na comunidade cientí­fica. Em adendo, os avanços tecnológicos como forma de prevenção para LPP"™s apresentou maior resolutividade em pacientes complexos. Com tudo, é necessário que mais estudos sejam realizados em outras unidades hospitalar com o uso desses instrumentos como aprofundamento na temática e para garantir sua eficácia.

Objetivo: estimar a prevalência do risco de lesão por pressão, identificar os fatores associados e estabelecer modelo de predição para seu desenvolvimento em pacientes atendidos por um programa de atenção domiciliar. Método: trata-se de um estudo transversal, realizado entre junho de 2017 e janeiro de 2018, com 131 pacientes atendidos pelo Programa Melhor em Casa de uma cidade do norte de Minas Gerais. Com auxí­lio de um instrumento foram coletados dados socioeconômicos, demográficos e clí­nicos. Realizou-se análise descritiva, bivariada e regressão de Poisson robusta e ajustada. Resultados: dos 131 pacientes, 76,3% apresentaram risco de lesão por pressão. As variáveis independentes que impactaram, de forma significativa e conjunta, no risco de lesão por pressão foram: "limitação", "relato de memória prejudicada", "incontinência", "lesão sacral" e "proeminência óssea". Conclusão: o risco de lesão por pressão é um achado comum em pacientes da atenção domiciliar e cuidados para sua prevenção devem ser estabelecidos.

Objetivo: Comparar os efeitos dos do uso de prata tópica versus curativos sem prata na redução da área de feridas infectadas. Tendo em vista o surgimento, nos últimos anos, dos curativos de prata no tratamento de feridas, tornando válido o levantamento das evidências sobre esse fato. Método: Este trabalho é uma revisão sistemática norteada pelas diretrizes do Prisma, utilizando a base de dados MedLine/Pubmed, SciELO e busca manual. Ensaios clí­nicos randomizados em inglês, português e espanhol foram incluí­dos, comparando tratamentos com prata tópica e sem prata na redução da exsudação da área de feridas infectadas. O CONSORT foi utilizado como método de avaliação da qualidade dos artigos, incluindo os com pontuação de pelo menos 70%. Resultados: foram encontrados quatro estudos que contemplam objetivos. Todos apresentaram superioridade em favor do uso de prata devido í  diminuição da área da ferida. Os principais riscos de viés considerados são os de desgaste, publicação, detecção e desempenho. Conclusão: O tratamento com prata mostrou-se superior ao tratamento com curativos que não utilizam prata na redução da área lesada em queimaduras, feridas cirúrgicas, úlceras, pés diabéticos e infectados. Entretanto, estudos com maior valor amostral ainda são necessários para esclarecer uma melhor abordagem.

Introdução: O HIV/Aids é uma doença de ní­vel pandêmico, e é um grande problema relacionado a saúde pública, contudo, ainda não tem cura e a eficácia do tratamento depende necessariamente da adesão í  terapia por toda a vida. Objetivo: Registrar os motivos de abandono aos antirretrovirais entre pacientes internados em um hospital referência em infectologia do Amazonas. Metodologia: Estudo descritivo, prospectivo. Resultados Foram entrevistados 60 pacientes portadores do ví­rus HIV internados na unidade hospitalar onde a maioria (70%) tinha a idade entre 19 a 40 anos, do total, 30% estavam em isolamento, sendo que 61,1% era por tuberculose e 16,6% era por COVID–19. Durante a entrevista 68,3% dos pacientes informaram que, em algum momento, por algum motivo, já descontinuaram o tratamento e a maioria (24,3%), relatou que o motivo principal da quebra da sequência da tomada aos antirretrovirais foi por motivos psicológicos (ansiedade, depressão, vergonha, baixa autoestima). Conclusão: a orientação que hoje prevalece é a de não suspender o tratamento mesmo quando há acompanhamento médico e a carga viral do paciente é indetectável.
