Published: July 2021

ABSTRACTThis research was designed to investigate the strategies used and challenges faced by lecturers in managing EFL speaking classes. The researchers used both classroom observation and semi-structured interviews in collecting the data. The participants of this research were three EFL lecturers teaching English Speaking classes at the English Department of Universitas Islam Negeri Ar-Raniry, Banda Aceh, Indonesia. These lecturers were selected purposively; all of them were those assigned to teach the speaking class. Insights of the lecturers on their experiences in managing speaking classes were investigated to examine strategies and challenges they faced. The findings suggest that the lecturers utilized several strategies such as setting the classroom, determining seating arrangements, fostering discipline, applying certain speaking activities, and providing interesting topics to discuss. The data also indicated that the lecturers faced challenges in managing their teaching. Issues such as lack of equipment or teaching media to support speaking activities, students’ lacked self-confidence, and lack of vocabulary were among the challenges faced by the lecturers.  ABSTRAKPenelitian ini bertujuan mendapat informasi tentang strategi dan tantangan yang dihadapi dosen di dalam mengelola kelas.

ABSTRACTThis study aims to identify whether Flipped Classroom strategy can enhance students’ grammatical competence. EFL students still found difficulties in understanding and mastering grammar despite its central role in learning a new language. As we are living in the digital era, we can optimize digital tools in teaching and learning to assist students and teachers. Furthermore, students nowadays are tech-savvy, so it would not be very difficult to integrate technology into classroom. The participants of this research were the tenth grade students at SMAN 4 Tangerang Selatan. Classroom Action Research (CAR) was implemented as the research design with two cycles which comprised three meetings in each cycle. The cycle consisted of planning, acting, observing, and reflecting. The instruments used were test, questionnaire, observation, and researcher’s field note. The results showed that 77.14% of students passed the minimum criterion score; further, the results among pre-test, post-test 1, and post-test 2 significantly increased. These findings indicate that Flipped Classroom have the potential to improve students’ grammatical competence.   ABSTRAKStudi ini bertujuan untuk meningkatkan kompetensi gramatikal siswa melalui strategi Flipped Classroom dan untuk mengetahui bagaimana strategi tersebut meningkatkan kompetensi gramatikal siswa.   Siswa yang menggunakan bahasa Inggris sebagai bahasa asing (EFL) masih mengalami kesulitan untuk memahami dan menguasai tata bahasa meskipun peran sentralnya dalam belajar bahasa.  Karena kita hidup di era digital, kita dapat mengoptimalkan alat digital dalam proses belajar-mengajar untuk membantu siswa dan guru.  Selain itu, siswa saat ini sudah paham teknologi sehingga tidak terlalu sulit untuk mengintegrasikan teknologi ke dalam kelas.

Published: July 2021

Introduction: Mesenchymal stem cell (MSC) transplantation has been reported as a promising therapy for acute limb ischemia (ALI). However, the treatment efficacy is limited to only certain improvements. Therefore, this study aims to improve the treatment efficacy of MSC transplantation through the use of MSC sheets produced from MSCs' cultured in fibrin scaffold (Fi-MSCs) in ALI models.

Methods: MSCs were isolated and expanded from human umbilical cord tissue. The fibril scaffold was produced from human umbilical cord blood. Fi-MSCs were prepared by mixing MSCs with fibril according to a published protocol, and the Fi-MSC sheets were implanted directly into ligated and transected sites in the hind limbs of ischemic models (treatment group — group I). The results were compared with that of the control group (group II) in which mice were injected with saline. The treatment efficacy was recorded and evaluated through the following assays: limb morphology, SpO2, blood perfusion, angiogenesis, and histological morphology on days 7, 14, and 28 after treatment.

Results: The results indicate that the transplantation of Fi-MSC sheets positively affected the acute ischemia hind-limb mouse models. On day 7 post-transplantation, the SpO2 index recorded at feet in group I (treatment) significantly increased from 79.24% + 1.43% to 89.40% + 1.65% (p-value < 0.05), while in group II (control), the SpO2 index slightly increased from 76.52% + 1.63% to 77.00 + 1.15 (p-value > 0.05). Besides, there were 60.00% (auto-recovery), 13.33%, and 26.67% mice at damage grades 0, I, and II, respectively, in the control group compared to 80%, 20%, and 0% mice at damage grades 0, I, and II, respectively. Moreover, in group I, all mice showed improved blood reperfusion, neovascular, and repaired muscle tissue compared to group II.

Conclusion: Fi-MSC sheet transplantation positively reduced injury and improved blood perfusion ALI in the Swiss mouse model.

The existence of schools is one component in supporting the goals of national education, where educational tasks can actually be categorized into "managerial" tasks which are managed by education managers assisted by education personnel in various fields of expertise. This shows that the sustainability of educational institutions cannot be separated from the applied managerial system. The application of management patterns both institutionally and with good resources will lead to an educational institution that is able to keep up with environmental changes.

Published: July 2021

Background: Systemic Lupus Erythematosus (SLE) is an autoimmune disease characterized by a spectrum of clinical manifestations, immunological abnormalities, and varied laboratories results. In children, SLE manifestation is particularly more severe, involving more organs. Hematological manifestation has been known as the most common manifestation. The purpose of this study was to describe the clinical manifestations and hematologic interpretation of pediatric SLE at initial presentation.Methods: This retrospective data collection study was conducted at the Department of Child Health Dr. Hasan Sadikin General Hospital Bandung on medical records from a two-year period of 2017–2018. The clinical manifestations were categorized into malar rash, discoid rash, photosensitivity, oral ulcers, arthritis, renal disorders, and neurological disorders. The hematologic interpretations were categorized into anemia, leukopenia, neutropenia, lymphopenia, and thrombocytopenia. Clinical manifestations and hematological interpretations were presented as occurrence percentages and stratified into three age-group of pre-pubertal, peri-pubertal, and post-pubertal.Results: Among 79 pediatric SLE patients (median age 14 years old; IQR 11–16), female gender was predominant. Abnormalities hematologic interpretation occurs in more than half of the patients (83.5%). Malar rash and anemia were the commonest findings among all age groups. Increased occurrence of neuropsychiatric and renal disorders were observed in all age-groups.Conclusions: Malar rash and anemia are important findings among pediatric SLE patients. Furthermore, the occurrences of the neuropsychiatric and renal disorders are also important.

Published: July 2021

Background: Calcium bentonite is a type of clay produced by a devitrification of volcanic ash which is often used as a traditional medicine to absorb toxins and waste products of metabolism. The aim of this study was to determine the lethal dose of calcium bentonite in Wistar rats to explore its toxicity level and safe use.Methods: Fifty male and female Wistar rats were randomly divided into five groups for each sex. The control group was given 5 cc aquadest whereas the other four groups received calcium bentonite solution of 50 mg/kgBW, 300 mg/kgBW, 2,000 mg/kgBW, and 5,000 mg/kgBW, respectively, at a single dose. The weight was observed for up to 7 days and analyzed using the unpaired t-test and Mann-Whitney test. The death rate was calculated using the probit analysis. Median lethal dose results were then classified according to Loomis Criteria. Results: No deaths occurred at the highest dose, suggesting that the median lethal dose value of calcium bentonite was >5,000 mg/kgBW. No weight loss occurred due to the administration of calcium bentonite and a significant increase in the body weight was even observed in the male rat group. Interestingly, a significant decrease was found in the female rats group when compared to the control group.Conclusions: Calcium bentonite is classified as a practically non-toxic material with a median lethal dose of over 5,000 mg/kgBW.

Published: July 2021

Abstract Fertilization greatly affects coconut productivity; nevertheless, information on crop nutrition is relatively scarce for coconut in the state of Pará, Brazil. This study evaluated the effect of fertilization with nitrogen (N), phosphorus (P), potassium (K), and magnesium (Mg) on the nutritional status and coconut yield under the edaphoclimatic conditions of the municipality of Moju, Pará State (Brazil). The experiment was conducted for 10 years on a SOCOCO® Farm and used a randomized block design with three replications. Three levels of P, K, and Mg were used in presence and absence of N. Response to fertilization in the treatments was studied in terms of leaf concentration of macronutrients (N, P, K, Ca, Mg and S) and micronutrients (B and Cl). We also assessed the number of coconuts/plant/year, fresh albumen weight (FAW)/coconut and FAW/ha/year. The results were subjected to the analysis of variance (p<0.05) and the means compared by the Tukey test. In general, N fertilization did not influence concentration of macronutrients and micronutrients in leaves. In turn, P, K and Mg fertilization influenced nutrition of coconut palm. P and K fertilizations, isolated or in combination, increased the production of coconut/plant and FAW/ha. From the 6th year of plant age, 54 kg/ha/year of P2O5 and 96 kg/ha/year of K2O are indicated for the coconut culture in the region of the current study. N fertilization did not influence production parameters and Mg fertilization increased production in the presence of K fertilization.
Kinetic parameters estimation for increasing the efficiency of nutrient absorption in fruit trees

Published: July 2021

Abstract The selection of rootstocks presenting traits of interest, such as resistance to pests and diseases, and compatibility with scion capable of producing fruits attractive to the market, has revolutionized fruit crops worldwide. However, the enormous potential of plants to be selected based on their nutrient uptake efficiency is yet to be properly explored; it can be done based on knowledge about kinetic parameters such as Influx, Maximum uptake velocity, Constant ion affinity with the carrier, and Minimum concentration. The adaptation of a methodology elaborated for annual crops to set kinetic parameters, as well as the Brazilian development of the Influx software, enabled selecting not only peach rootstocks with different nutrient uptake capacities, but also observing the influence the grafting of a particular cultivar crown has on rootstock’s ability to uptake a given nutrient from the soil. Thus, fruit tree rootstocks and cultivars can always be selected based on traits desired by fruit growers and consumers, with emphasis on yield and quality of fruits. They can also be more efficient in taking up nutrients from low natural-fertility soils that require lower nutrient amounts, a fact that increases fertilizer use rationalization and reduces environmental contamination processes resulting from excessive nutrient applications.
Growth and Security Under Welfare-Corporate Capitalism and Market Socialism
Authors: GORDON MYRON J.
Published: July 2021

ABSTRACT A pure capitalist system has private ownership of wealth and administration of the economy via markets. As pure socialist system has stare ownership and administration by a bureaucracy. One offers growth and insecurity, and the other offers security and stagnation. In reality, neither has existed nor can exist for long. The feasible alternatives are welfare capitalism and market socialism. Over the last fifty years, the transition from welfare to corporate capitalism has taken place in the West under U. S. leadership. It has resulted in increasing insecurity and inequality within rich countries and between rich and poor countries. The transition from bureaucratic to market socialism in China over the last twenty years has brought to its people amazing growth and prosperity- and many of the ills of a market economy. It remains to be seen whether market socialism in China is an attractive alternative to welfare capitalism, or is no more than a transition to corporate capitalism.
Regimes e Políticas Cambiais: Uma Visão Geral
Authors: CORDEN W. MAX
Published: July 2021

RESUMO Este artigo apresenta os princípios econômicos gerais da política cambial e fornece uma visão geral dos quatro casos de países que foram incluídos nesta edição especial da revista: México, Brasil, Argentina e Venezuela. São discutidos três principais regimes monetários - o regime fixo, mas ajustável (FBAR), a taxa firmemente fixa e o regime de taxa flutuante. Ao mesmo tempo, o artigo distingue entre duas abordagens principais da política cambial: a abordagem da âncora nominal e a abordagem de metas reais. O autor identifica os custos e benefícios da implementação desses vários regimes cambiais através das diferentes fases da estabilização macroeconômica e do ajuste estrutural. Embora a dolarização tenha se tornado cada vez mais discutida como outra opção de política monetária na América Latina, o autor observa que essa tendência ainda é incipiente demais para ser abordada neste artigo.
Os estados de reformas defasadas e a questão da desvalorização: a reação da Venezuela aos choques exógenos de 1997-98
Authors: CORRALES JAVIER
Published: July 2021

RESUMO Tendo acabado de completar sua segunda “década perdida” consecutiva, o caso venezuelano confirma que não há atalhos para uma boa gestão política econômica na era de alta mobilidade de capital e fluxos de capital securitizados. A manutenção de uma estratégia cambial atrapalhada triunfou, pelo menos por enquanto, e permitiu que uma coalizão de elite no nível executivo prevalecesse na busca de uma política macroeconômica menos do que ideal. O autor argumenta que a Venezuela evitou uma desvalorização total, do estilo mexicano ou brasileiro, em virtude da capacidade do Banco Central de gerenciar efetivamente a taxa de câmbio. No entanto, esse foi o único bolso da modernização, pois os formuladores de políticas de todo o resto da burocracia do estado rejeitaram os tipos de reformas de mercado que serão necessárias para reverter o desempenho altamente medíocre do país. Embora os altos preços do petróleo desde 1999 tenham proporcionado aos políticos e formuladores de políticas o “luxo” de ser um retardatário da reforma, os líderes venezuelanos parecem determinados a aprender da maneira mais difícil que as tendências internacionais podem voltar a balançar contra eles a qualquer momento.

Published: July 2021

Resumo O presente artigo faz uma revisão bibliográfica e aborda os principais índices utilizados no monitoramento e análise de secas. Além disso, o texto ainda discorre sobre as metodologias empregadas mundialmente no monitoramento e previsão desses eventos. As secas ocorrem quando existe um déficit de precipitação comparado à média histórica da região. Elas podem ser diagnosticadas por meio de índices que identificam os períodos de escassez ou de disponibilidade hídrica através de equações. Dessa forma, é possível determinar a intensidade, frequência e duração dos eventos de seca. Nesse âmbito, alguns países implementaram seus próprios sistemas de monitoramento e alerta precoce das secas como o Monitor de Secas dos Estados Unidos, o Monitor de Secas da Europa e o Monitor de Secas do Brasil. Onde estes, utilizam de forma conjunta ou isolada as informações provenientes dos índices, a fim de identificar e caracterizar os eventos de seca. Desse modo, pode haver um melhor planejamento das instituições responsáveis, adoção de planos emergenciais e mitigação de impactos.

Published: July 2021

ABSTRACT Objective: Our aim was to describe the foot alignment in National Football League (NFL) players with different symptomatic foot and ankle pathologies using weightbearing cone-beam computed tomography (WBCBCT), comparing them to normally aligned feet as control group. Methods: 41 feet (36 active NFL players) were assessed using WBCBCT and compared to 20 normally aligned controls from a normal population. Measurements included: Foot and Ankle Offset (FAO); Calcaneal Offset (CO); Hindfoot Alignment Angle (HAA); angle between inferior and superior facets of the talus (Inftal-Suptal); angle between inferior facet of the talus and the horizontal/floor (Inftal-Hor); Forefoot Arch Angle (FAA); navicular- and medial cuneiform-to-floor distance. Results: NFL athletes showed a neutrally aligned hindfoot when compared to controls (FAO: 1% vs 0.5%; CO: 2.3 mm vs 0.8 mm; HAA: 2.9° vs 0.8° in two groups, with all p > 0.05) and a normal morphology of the subtalar joint (no difference in Inftal-Suptal and Inftal-Hor angles). Conversely, in athletes we found a decreased medial longitudinal arch (FAA: 15° vs 18.3°, p = 0.03) with smaller navicular (38.2 mm vs 42.2 mm, p = 0.03) and medial cuneiform (27 mm vs 31.3 mm, p = 0.01) mean distances to the floor when compared to controls. Conclusion: In our series, NFL players presented a lower medial longitudinal arch than controls but a neutrally aligned hindfoot. WBCBCT may help shed light on anatomical risk factors for injuries in professional players. Level of Evidence III, Retrospective comparative study.

ABSTRACT Objective: To evaluate and compare anatomical measurements of C7, T1 and T2 vertebrae in children from 3 to 12 years of age to provide useful epidemiological data for determining the safe anatomical margin for transpedicular and translaminar fixation with screws in this population. Methods: This observational retrospective cross-sectional study evaluated 76 computed tomography scans obtained over 6 months, analyzing the following parameters: the angle of attack, length, thickness and diameter of the pedicle; and the angle of attack, length and thickness of the lamina. Results: The lamina length and thickness, as well as pedicle length varied in size according to age. Although the angle of attack was similar across different ages, age-dependent variation occurred in the T1 vertebra. Conclusion: Screws with a 3.5 mm diameter are safe to use in the C7 and T2 pedicles, while the T1 pedicle allows the introduction of larger screws ranging from 3.5-4.5 mm in diameter. In the lamina, 3.5 mm screws are safe for use only in children older than 7 years. However, each case should be analyzed individually, with the present study not aiming to replace the preoperative use of CT. Level of Evidence III, Retrospective comparative study.

ABSTRACT Objective: To determine the frequency of hip pain in competitive bodybuilders over three different bodybuilding competitions. Methods: This study evaluated bodybuilders recruited from three competitions during the year of 2016. All participants provided their informed consent and the study received IRB approval. Training routine, health condition, level of success on competitions, history of hip pain and physical examination of the hip were evaluated. Results: 113 bodybuilders were evaluated, mean age was 30.5 ± 8.65 years and mean BMI was 25.2 ± 3.65 kg/m2. Mean values for hip flexion, adduction, abduction, internal rotation, external rotation and distance between the knee and the table (FABER distance) were 116 ± 13, 23 ± 8, 71 ± 12, 40 ± 10, 36 ± 9 and 19 ± 4, respectively. Eight (7%) participants presented hip pain within the week prior to examination and only 2 (1,7%) presented with anterior impingement sign. None of the athletes who reported hip pain interrupted their physical training or performance. Conclusion: Symptomatic athletes continued their training program under the presence of hip pain. The frequency of hip pain among bodybuilders is high and may be underestimated in this study. Level of Evidence IV, Case series.

ABSTRACT Objective: To evaluate the conduct of Brazilian orthopedists regarding preventive treatment after fragility fracture surgery. Methods: A questionnaire was applied to Brazilian orthopedists. Statistical analyses were performed using the SPSS 16.0 program. Results: 257 participants were analyzed. Most participants, 90.7% (n = 233), reported that they cared for patients with fractures and 62.3% (n = 160) treated them. The most indicated treatments were vitamin D (22.6%; n = 134) and calcium supplementation (21.4%; n = 127). According to the experience of the physicians - experienced (n = 184) and residents (n = 73) - fragility fractures were more common in the routine of residents (98.6%; n = 72) than experienced physicians (87.5%; n = 161), p = 0.0115. While treatment conduction was more reported by experienced physicians (63.6%; n = 117) than residents (58.9%; n = 43), p = 0.004. More experienced orthopedists (21.4%; n = 97) indicated treatment with bisphosphates than residents (14.2%; n = 20), p = 0.0266. Conclusion: Although most professionals prescribe treatment after fragility fracture surgery, about 40% of professionals still do not treat it, with differences in relation to experience. In this sense, we reinforce the importance of secondary prevention in the management of fragility fractures. Level of Evidence II, Prospective comparative study.

ABSTRACT Objective: To compare the long-term effects of a brace designed to stabilize the patellofemoral (PF) joint in comparison to a standard neoprene sleeve for the knee with patellar hole in patients with patellofemoral osteoarthritis (PFOA). Methods: 38 patients with PFOA and comorbidities received either a functional PF brace (Study Group, SG) or a neoprene sleeve for the knee (Control Group, CG). Both groups received clinical treatment to OA and comorbidities according to a program from the institution. Patients were evaluated with Western Ontario and MacMaster (WOMAC) and Lequesne questionnaires, 30-second chair stand test (30CST), Timed Up and Go (TUG), anthropometric measures and self-reported physical activity in minutes/week at inclusion, one, three and twelve months after placing the brace. X-Rays were taken to measure the angles. Results: At one year there was more abandonment in the CG without differences in weight and body mass index between groups during the study. The SG maintained improvements in Lequesne and WOMAC total and subsets during the year, whereas the CG returned to baseline values for pain, function and total (p < 0.01). TUG and 30CST results were always better in the study group without any clinically important improvement in both groups. Conclusion: Long-term use of functional brace added to self-management program improves pain and function in patients with PFOA. Level of Evidence II, Lesser quality RCT (eg, < 80% followup, no blinding, or improper randomization).

Abstract This article aims to evaluate the quality of Brazilian school meal menus. Cross-sectional study that analyzed 2,500 menus of 500 Brazilian municipalities. The menus were evaluated based on the Quality Index for School Meal Menus (IQCAE - Indicador de Qualidade para Cardápios da Alimentação Escolar). The data were submitted to descriptive analysis. We found that 29,4% of menus presented high quality; 50,6%, regular quality; and 20%, low quality. Grains and tubers (86%) and Meat and eggs (67%) were the groups most found in menus, followed by Legumes (42,16%), Vegetables (40%), Fruits (35,56%), and Dairy products (18,6%); the frequency of Cured meats and sausages (8,68%) and Sweets as meals (3,64%) was lower. Among other components, 84,6% of the menus offered Sweets as dessert in none or one day a week; ultra-processed foods appear in 65,6% of menus at least once a week. In 22% of the menus, meal time was compatible with type meal served. Important food for child nutrition, such as dairy, vegetables, and fruits, are not regularly provided by school meals. Despite the advances in policy management, the presence of ultra-processed foods at least once a week is still frequent in the menus.

Resumo Objetivou-se estimar a frequência do consumo regular de café da manhã (cinco ou mais vezes na semana) entre adolescentes e investigar sua associação com variáveis demográficas, turno escolar e trabalho, comportamentos relacionados à saúde, práticas alimentares e consumo de alimentos. Realizou-se estudo transversal em 30 escolas estaduais de Curitiba, Paraná, entre março de 2016 e maio de 2017, com participação de 1.232 adolescentes. A prevalência de consumo regular de café da manhã foi de 58,6% (IC95% 53,9; 63,2). Após análise ajustada observou-se maior consumo regular de café da manhã entre adolescentes que: frequentavam os turnos vespertino e intermediário/integral; realizavam atividade física supervisionada; relatavam dormir mais que oito horas/noite; relatavam almoçar e jantar com a família todos os dias e; realizavam quatro refeições ou mais por dia. A frequência semanal do café da manhã foi associada ao maior consumo de leite e derivados, e ao menor consumo de macarrão instantâneo e refrigerantes. Destaca-se que o hábito de realizar o desjejum esteve associado com práticas alimentares e hábitos saudáveis, reforçando seu valor enquanto marcador de outros comportamentos relacionados à saúde. Sua realização deve ser incentivada entre os adolescentes.

Resumo O presente estudo tem como objetivo avaliar os fatores relacionados à disfunção familiar (DF) entre 227 nonagenários e centenários identificados e avaliados no domicílio, aleatoriamente selecionados, em Porto Alegre, Rio Grande do Sul. A DF foi avaliada pelo instrumento “APGAR da família”, sendo considerado, no presente estudo, de zero a seis com DF e de sete a dez sem DF. Foram avaliados, entre abril e novembro de 2016, dados sociodemográficos, econômicos, funcionalidade física, autopercepção de saúde, comorbidades, sintomas depressivos, função cognitiva, suporte e interação social. A média do APGAR foi de 9,05±1,81, a DF ocorreu em 9,69% dos participantes. Foram relacionados à DF a autopercepção de saúde (p=0,0003), número de sintomas depressivos (p<0,0001), ter ajuda em caso de doença (p=0,0090) e necessidade de ajuda para administrar medicamentos (p=0,0602). Na análise ajustada, foram independentemente associados à DF em nonagenários e centenários a autopercepção de saúde, a presença de sintomas depressivos e a necessidade de ajuda para administrar medicamentos. Conclui-se que esses fatores parecem interferir na satisfação do nonagenário ou centenário com suas relações familiares.

Resumo Como parte do estudo de avaliabilidade da avaliação da implementação do Prontuário Eletrônico do Paciente (PEP), o objetivo desta Revisão Sistemática (RS) foi identificar os domínios de avaliação a serem abordados. Esta RS, alinhada com o Cochrane Handbook for Systematic Reviews of Interventions e o Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) englobou artigos publicados de 2006 até 2019. Realizou-se a busca nas bases de dados eletrônicas SciELO, Oásis IBICT, BVS Regional e Scopus. A busca retornou 1.178 artigos, sendo 42 que atenderam aos critérios de inclusão. A maioria dos estudos utilizaram métodos qualitativos para análises. As publicações ocorreram entre 2006 e 2019, tendo sua concentração em 2017 com 9 (21%) artigos publicados. Não foram identificados estudos publicados em 2008 e 2009. Somente 10 estudos incluíam descrição, análises ou resultados relacionados aos domínios de implementação. Os principais domínios em que o PEP foi problematizado foram: subutilização; resistência dos profissionais ao seu uso; ênfase na usabilidade; e o PEP como repositório de informações. Apesar da inclusão de todos os estudos que contemplaram os princípios e diretrizes da Política Nacional de Humanização (PNH), eles ainda são incipientes.

Resumo Este estudo objetivou estimar a prevalência de Transtornos Mentais Comuns (TMC) em estudantes universitários, analisando a correlação com o uso de internet e com a utilização de estratégias de enfrentamento ante ao isolamento social na pandemia de COVID-19. Trata-se de um estudo transversal, quantitativo, com amostra não probabilística, constituída por 275 estudantes. A coleta de dados foi realizada online, por meio dos instrumentos Self Report Questionnaire-20, Escala de Uso Problemático de Internet e Inventário de Estratégias de Enfrentamento. A análise de dados foi descritiva e inferencial, sendo também realizada uma análise de regressão linear múltipla. A população pesquisada apresentou uma prevalência de TMC de 58,5%, que correlacionou-se positivamente com a frequência de uso de internet, e com a utilização de estratégias de enfrentamento evitativas, baseadas no confronto, orientadas para a busca de suporte social e aceitação de responsabilidade (p<0,05). A presença de TMC e a utilização de estratégias de enfretamento baseadas no confronto foram as variáveis que melhor explicaram o uso problemático de internet (R2=0,33%; p<0,00). A intensa sociabilidade digital deve ser levada em consideração nas ações de cuidado em saúde mental direcionadas aos universitários no contexto da COVID-19.

Resumo Este estudo investiga a associação entre diagnóstico autorreferido de Doença Crônica Não Transmissível (DCNT) e adesão ao distanciamento social e utilização dos serviços de saúde durante a pandemia de COVID-19. Estudo transversal com adultos brasileiros que participaram da ConVid Pesquisa de Comportamentos, realizada de 24 de abril a 24 de maio de 2020, via web (n = 45.161). Considerou as DCNT: diabetes, hipertensão, doença respiratória, doença do coração e câncer. Avaliou a utilização de serviços de saúde e a adesão ao distanciamento social. Estimou as prevalências e razões de prevalências ajustadas (RPa). 33,9% (IC95%: 32,5-35,3) referiu uma ou mais DCNT. Indivíduos com DCNT tiveram maior adesão ao distanciamento social intenso (RPa:1,07; IC95%:1,03-1,11), procuraram mais o serviço de saúde (RPa:1,24; IC95%:1,11-1,38) e tiveram mais dificuldades para marcar consulta (RPa:1,52; IC95%:1,35-1,71), conseguir atendimento de saúde (RPa:1,50; IC95%:1,22-1,84) e medicamentos (RPa:2,17; IC95%:1,77-2,67), realizar exames (RPa:1,78; IC95%:1,50-2,10) e intervenções programadas (RPa:1,65; IC95%:1,16-2,34). A presença de DCNT associou-se à maior adesão ao distanciamento social, procura por atendimento de saúde e dificuldade na utilização dos serviços de saúde.
O insustentável peso da autoimagem: (re)apresentações na sociedade do espetáculo
Authors: Oliveira Michelle Rodrigues de , Machado Jacqueline Simone de Almeida
Published: July 2021

Resumo Este estudo teve por objetivo identificar a autoimagem apresentada pelos adolescentes, frente à uma sociedade tecida pela exigência de imagem e padrões corporais considerados perfeitos, compreendendo a influência das relações sociais e da mídia na construção de suas identidades. Trata-se de uma pesquisa qualitativa, alicerçada na História Oral, envolvendo 13 adolescentes de 15 a 19 anos, dos sexos feminino e masculino, alunos de uma escola pública de Minas Gerais. Utilizou-se de entrevistas com roteiro semiestruturado para a coleta dos dados, que posteriormente foram interpretados por análise temática de conteúdo, proposta por Bardin. Os achados foram dispostos em duas categorias: 1 - A imagem de si no processo de construção da identidade do adolescente e 2 - O ideal estético da sociedade do espetáculo. Os relatos demonstram a forte influência das tecnologias na formação de suas identidades e possíveis consequências que a busca de uma imagem espetacular para atender aos padrões estéticos do mundo virtual ou real podem trazer aos adolescentes. Esta autoimagem idealizada revela o modo de ser e viver da contemporaneidade, os valores, a fragilidade e a superficialidade das relações estabelecidas na sociedade do espetáculo.
