Abstract Objective To describe acute kidney injury prevalence in young adults diagnosed with COVID-19 admitted to the Intensive Care Unit. Methods This is a retrospective, quantitative and analytical study. The sample consisted of young adults (20 to 40 years old) admitted to Intensive Care Units, diagnosed with SARS-CoV-2 infection between March and December 2020. Data were obtained through electronic medical records, and kidney injury acute was defined by the creatinine value, according to the Kidney Disease Improving Global Outcomes guidelines criteria. Statistical significance was p≤0.05. Results A total of 58 young adults were hospitalized, 63.8% of whom were male. Hypertension was present in 39.6%, obesity in 18.9%, and diabetes mellitus in 8.6%. Acute kidney injury was identified in 55.1%, with stage 3 predominating in 43.1% of them. In these patients, the use of mechanical ventilation and vasoactive drugs was significant in 92% as well as respiratory organ dysfunction (80%), followed by renal organ dysfunction (76%). Risk factors such as kidney transplantation or chronic kidney disease and obesity increased by 12.3 and 9.0 times, respectively, the chances of developing acute kidney injury. Conclusion This study demonstrated a high kidney injury prevalence in young adults and its association with previous comorbidities. Obesity, kidney transplantation and chronic kidney disease increased the chance of young adults to develop acute kidney injury, resulting in outcomes in favor of morbidity and mortality.

Abstract Analyze the experience of situations of dating violence during adolescence. Qualitative approach research, of the strategic social research type, carried out with 31 teenagers aged 14 to 19, interviewed remotely, with a semi-structured script, from November 2020 to March 2021. Data analysis was based on dialogic principles, organizational and hologramatic resource of the Complex Paradigm. Participants understand what constitutes violence, listing its main forms of manifestation. However, they show difficulties in recognizing situations of abuse experienced in the relationship as violent acts, often naturalizing aggression and legitimizing the actions of domination experienced on a daily basis. The importance of recognizing situations experienced in the routines of emotional relationships that can be configured as violence is highlighted, in order to raise awareness about the non-naturalization of abuse and aggression within these relationships, even if verbal, especially during adolescence.

Resumo Analisar a vivência de situações de violência no namoro na fase da adolescência. Pesquisa de abordagem qualitativa, do tipo pesquisa social estratégica, realizada com 31 adolescentes de 14 a 19 anos, entrevistados de forma remota, com roteiro semi-estruturado, no período de novembro de 2020 a março de 2021. A análise dos dados foi fundamentada nos princípios dialógico, recurso organizacional e hologramático do Paradigma Complexo. Os participantes compreendem o que se configura como violência, elencando suas principais formas de manifestação. No entanto, mostram dificuldades em reconhecer as situações de abuso vivenciadas no relacionamento como atos violentos, muitas vezes naturalizando as agressões e legitimando as ações de dominação vivenciadas cotidianamente. Evidencia-se a importância do reconhecimento de situações vivenciadas nas rotinas das relações afetivas que possam se configurar como violência, de forma a se conscientizar sobre a não naturalização dos abusos e agressões dentro dessas relações, mesmo que verbais, principalmente na fase da adolescência.

ABSTRACT BACKGROUND AND OBJECTIVES: Wound complications and pharmacological pain relief methods used at the skin surgical site after cesarean delivery may result in women’s physical and emotional burden. Thus, nonpharmacological treatments must be explored to avoid these complications and side effects on maternal health. The objective of this study was to investigate the effects of Combined Ultrasound and Electric Field Stimulation (CUSEFS) on cicatricial pain and functional capacity in immediate cesarean delivery. METHODS: This study has a randomized clinical trial, double-blind, and placebo-controlled design. Thirty women (25.7±5.0 years) in immediate postpartum were randomly assigned to three groups: Control (CG, n:9), CUSEFS (TG, n:11), and Placebo (PG, n:10). CUSEFS was performed once for 20 minutes. Cicatricial pain (McGill Pain Questionnaire) and functional capacity (Functional Capacity Check) was assessed at baseline, after the intervention, and after 30 minutes. Cohen’s (d) and Mixed-design analysis of variance were used to compare groups. RESULTS: Immediately after the intervention, TG showed a decrease in cicatricial pain compared with CG in sensory (d:3.8 to 4.0), affective (d:4.0), and total categories (d:3.9). In functional capacity, TG had less difficulty than CG at walking (d:0.6) and lying down (d:1.1), and PG at rest (d: 0.9). CONCLUSION: CUSEFS might be a resource for managing cicatricial pain and functional capacity in immediate cesarean delivery. Further studies with longer duration and different CUSEFS doses/parameters are required.

RESUMO JUSTIFICATIVA E OBJETIVOS: As complicações na ferida e o uso de métodos farmacológicos de alívio da dor no local cirúrgico após a cesariana podem resultar em sobrecarga física e emocional para a mulher. Assim, tratamentos não farmacológicos devem ser explorados para evitar essas complicações e efeitos adversos à saúde materna. O objetivo deste estudo foi investigar os efeitos da terapia combinada de estimulação elétrica por meio do ultrassom (CUSEFS) na dor cicatricial e na capacidade funcional no pós-parto imediato de cesariana. MÉTODOS: Este estudo possui um desenho de ensaio clínico randomizado, duplo-cego e controlado por placebo. Trinta mulheres (25,7±5,0 anos) em pós-parto imediato de cesariana foram distribuídas aleatoriamente em três grupos: Controle (CG, n:9), CUSEFS (TG:11) e Placebo (PG, n:10). O CUSEFS foi realizado uma vez por 20 minutos. A dor cicatricial (Questionário de Dor McGill) e a capacidade funcional (Functional Capacity Check) foram avaliadas no início, após a intervenção e após 30 minutos. As análises de variância de design misto e Cohen (d) foram usadas para comparar os grupos. RESULTADOS: Imediatamente após a intervenção, o TG apresentou diminuição na dor cicatricial em relação ao CG nas categorias sensorial (d:3,8 a 4,0), afetiva (d:4,0) e total (d:3,9). Na capacidade funcional, o TG apresentou menor dificuldade que o CG na marcha (d:0,6) e deitado (d:1,1), e que o PG em repouso (d:0,9). CONCLUSÃO: O CUSEFS pode ser um recurso para o manejo da dor cicatricial e da capacidade funcional imediatamente após a cesariana. Além disso, são necessários mais estudos com maior duração e diferentes doses/parâmetros de CUSEFS.

ABSTRACT Background: New-onset chronic pain has been acknowledged as part of the post-COVID-19 condition. However, available fine-grained data about its clinical phenotype, trajectories and main associated characteristics remain scarce. We described the distinct temporal evolutions of post-COVID-19 pain and their epidemiological and phenotypical features. Methods: A prospective cross-sectional study enrolled post-COVID-19 condition patients (i.e. who had persisting COVID-19-related symptoms over 30 days since their first positive laboratory test), whose COVID-19 diagnosis had been supported by RT-PCR of oral/nasopharyngeal swab or serology. They underwent in-person evaluations with a structured interview, pain and quality-of-life-related questionnaires and thorough physical examination. Chronic pain (CP) and probable neuropathic pain (NP) were defined according to IASP criteria. Results: The present study included 226 individuals, 177 (78.3 %) of whom presented over 3 months since their first COVID-19 symptom. New-onset pain occurred in 170 (75.2 %) participants and was chronic in 116 (68.2 %). A chronic course was associated with COVID-19-related hospitalization, new-onset fatigue, lower cognitive performance, motor and thermal sensory deficits, mood and sleep impairments and overall lower quality-of-life levels. Probable NP occurred in only 7.6 % new-onset pain patients, and was associated with pain chronification, new-onset fatigue, motor and thermal sensory deficits, mechanical allodynia and lower rates of SARS-CoV-2 vaccination. Previous CP was reported by 86 (38.1 %) individuals and had aggravated after the infection in 66 (76.7 %) of them, which was associated with orthostatic hypotension. Conclusions: Post-COVID pain phenomena follow different paths, which are associated with specific clinical and epidemiological features, and possibly distinct underlying mechanisms, prognostic and therapeutic implications. Significance: COVID-19-related pain usually follows a chronic course and is non-neuropathic. Its possible courses and phenotypes are associated with distinct clinical and epidemiological features. This suggests differing underlying mechnisms, which may have significant prognostic and therapeutic implications.

RESUMEN Antecedentes: El dolor crónico de nueva aparición se considera que forma parte de la condición o afección post-COVID-19. Sin embargo, los datos detallados existentes sobre el fenotipo clínico, las trayectorias y las principales características asociadas siguen siendo escasos. Describimos las distintas evoluciones temporales del dolor post-COVID-19 y sus rasgos epidemiológicos y fenotípicos. Métodos: Estudio prospectivo y transversal de pacientes con afección post-COVID-19 (es decir, con síntomas persistentes relacionados con la COVID-19 durante 30 días desde la primera prueba positiva de laboratorio) cuyo diagnóstico de COVID-19 estuviera basado en la RT-PCR de un frotis oral/nasofaríngeo o una serología. Se sometieron a evaluaciones presenciales mediante una entrevista estructurada, cuestionarios de dolor y calidad de vida y una exploración física exhaustiva. El dolor crónico (DC) y el dolor neuropático (DN) probablemente se definieron conforme a los criterios IASP. Resultados: El presente estudio incluyó 226 individuos, 177 (78,3 %) de los cuales se presentaron pasados más de 3 meses desde el primer síntoma de COVID-19. Tenían dolor de nueva aparición 170 (75,2 %) de los participantes y dolor crónico 116 (68,2 %). El curso crónico se asociaba a hospitalización por COVID-19, fatiga de nueva aparición, menor rendimiento cognitivo, déficits motores y sensitivos térmicos, alteraciones del ánimo y el sueño, y niveles generalmente inferiores de calidad de vida. El DN probable afectaba a solo el 7,6 % de los pacientes con dolor de nueva aparición y se asociaba a cronificación del dolor, fatiga de nueva aparición, déficits motores y de sensación térmica, alodinia mecánica y tasas menores de vacunación frente al SARS-CoV-2. Referían DC previo 86 (38,1 %) individuos, y este había empeorado tras la infección en 66 (76,7 %) de ellos, lo que se asociaba a hipotensión ortostática. Conclusiones: Los fenómenos dolorosos post-COVID siguen diferentes trayectorias que se asocian a rasgos clínicos y epidemiológicos específicos, y posiblemente a distintos mecanismos de base y diferentes implicaciones pronósticas y terapéuticas. Significado: El dolor relacionado con la COVID-19 sigue normalmente un curso crónico y no es neuropático. Los posibles cursos y fenotipos se asocian a rasgos clínicos y epidemiológicos distintos. Esto sugiere que los mecanismos de base difieren, lo que podría tener implicaciones pronósticas y terapéuticas importantes.

ABSTRACT Objective: To analyze the factors associated with the increase in domestic violence among teachers in the initial period of the pandemic. Methods: Cross-sectional and analytical study, of the websurvey type, carried out with teachers of public basic education in Minas Gerais, Brazil. Data collection took place from August to September 2020, via a digital form. The dependent variable was self-reported domestic violence. Poisson regression was used. Results: 539 teachers participated in the study in situations of domestic violence in the pandemic, of which 6.3% (n = 34) decreased a little and a lot, 58.3% (n = 314) remained the same and 35.4% (n = 191) increased a little and a lot. In the adjusted analysis, a higher prevalence of increased domestic violence was observed among teachers who reported difficulty with teaching work (PR = 1.38; 95%CI 1.01;1.89); with full adherence to social distancing (PR = 1.33; 95%CI 1.01;1.76); worsening of health status (PR = 1.70; 95%CI 1.23;2.36) and in teachers who felt sad or depressed many times or always (PR = 1.57; 95%CI 1.15;2.16). Conclusion: The increase in domestic violence of the pandemic in teachers was associated with work characteristics and mental health conditions.

RESUMO Objetivo: Analisar os fatores associados ao aumento da violência doméstica entre professores no período inicial na pandemia. Métodos: Estudo transversal e analítico, do tipo websurvey , realizado com professores da educação básica pública de Minas Gerais, Brasil. A coleta de dados ocorreu de agosto a setembro de 2020, via formulário digital. A variável dependente foi o autorrelato da violência doméstica. Utilizou-se a Regressão de Poisson. Resultados: Participaram do estudo 539 professores em situação de violência doméstica na pandemia, dos quais 6,3% (n = 34) diminuíram um pouco e muito, 58,3% (n = 314) permaneceram o mesmo e 35,4% (n = 191) aumentaram um pouco e muito. Na análise ajustada, observou-se maior prevalência do aumento da violência doméstica entre os professores que referiram dificuldade com o trabalho docente (RP = 1,38; IC95% 1,01;1,89); com adesão total ao distanciamento social (RP = 1,33; IC95% 1,01;1,76); piora no estado de saúde (RP = 1,70; IC95% 1,23;2,36) e que se sentiram tristes ou deprimidos muitas vezes ou sempre (RP = 1,57; IC95% 1,15;2,16). Conclusão: O aumento da violência doméstica da pandemia em professores foi associado a características laborais e condições de saúde mental.

Abstract Pitaya is a rich source of bioactive compounds, such as polyphenols and betalains. Moreover, these compounds has been associated with reduced risk of type 2 diabetes mellitus. The aim of this study is to evaluate the effect of this fruit on glycemia and oxidative stress in aloxan-induced diabetic mice. Thus, considering that In the in vivo assays, the mice were divided into 5 groups (n = 6): (a) healthy group treated with water; (b) diabetic mice treated with metformin at 200 mg/kg body weight diluted in water; (c) untreated diabetic mice; (d) diabetic mice treated with pitaya at 200 mg/kg and (e) diabetic mice treated with pitaya at 400 mg/kg of body weight diluted in water. The results shows that pitaya was able significantly to reduce blood glucose (p < 0.05) (200 mg/kg); significantly reduce cholesterol (200 and 400 mg/kg) and significantly increase HDL-c (400 mg/kg) levels. In the oxidative stress experiment, Malondialdehyde levels in the liver were significantly reduced (p < 0.05) in the groups treated with pitaya, when compared to the other groups, suggesting lower lipid peroxidation. The consumption of pitaya reduced the blood glucose and cholesterol and increase the HDL, in addition, the lipid peroxidation - which is common in diabetic patients, was reduced.

Abstract Background Cardiovascular complications of COVID-19 are important aspects of the disease’s pathogenesis and prognosis. Evidence on the prognostic role of troponin and myocardial injury in Latin American hospitalized COVID-19 patients is still scarce. Objectives To evaluate myocardial injury as independent predictor of in-hospital mortality and invasive mechanical ventilation support in hospitalized patients, from the Brazilian COVID-19 Registry. Methods This cohort study is a substudy of the Brazilian COVID-19 Registry, conducted in 31 Brazilian hospitals of 17 cities, March-September 2020. Primary outcomes included in-hospital mortality and invasive mechanical ventilation support. Models for the primary outcomes were estimated by Poisson regression with robust variance, with statistical significance of p<0.05. Results Of 2,925 patients (median age of 60 years [48-71], 57.1% men), 27.3% presented myocardial injury. The proportion of patients with comorbidities was higher among patients with cardiac injury (median 2 [1-2] vs. 1 [0-2]). Patients with myocardial injury had higher median levels of brain natriuretic peptide, lactate dehydrogenase, creatine phosphokinase, N-terminal pro-brain natriuretic peptide, and C-reactive protein than patients without myocardial injury. As independent predictors, C-reactive protein and platelet counts were related to the risk of death, and neutrophils and platelet counts were related to the risk of invasive mechanical ventilation support. Patients with high troponin levels presented a higher risk of death (RR 2.03, 95% CI 1.60-2.58) and invasive mechanical ventilation support (RR 1.87, 95% CI 1.57-2.23), when compared to those with normal troponin levels. Conclusion Cardiac injury was an independent predictor of in-hospital mortality and the need for invasive mechanical ventilation support in hospitalized COVID-19 patients.

Resumo Fundamento As complicações cardiovasculares da COVID-19 são aspectos importantes da patogênese e do prognóstico da doença. Evidências do papel prognóstico da troponina e da lesão miocárdica em pacientes hospitalizados com COVID-19 na América Latina são ainda escassos. Objetivos Avaliar a lesão miocárdica como preditor independente de mortalidade hospitalar e suporte ventilatório mecânico em pacientes hospitalizados, do registro brasileiro de COVID-19. Métodos Este estudo coorte é um subestudo do registro brasileiro de COVID-19, conduzido em 31 hospitais brasileiros de 17 cidades, de março a setembro de 2020. Os desfechos primários incluíram mortalidade hospitalar e suporte ventilatório mecânico invasivo. Os modelos para os desfechos primários foram estimados por regressão de Poisson com variância robusta, com significância estatística de p<0,05. Resultados Dos 2925 pacientes [idade mediana de 60 anos (48-71), 57,1%], 27,3% apresentaram lesão miocárdica. A proporção de pacientes com comorbidades foi maior nos pacientes com lesão miocárdica [mediana 2 (1-2) vs. 1 (0-20)]. Os pacientes com lesão miocárdica apresentaram maiores valores medianos de peptídeo natriurético cerebral, lactato desidrogenase, creatina fosfoquinase, N-terminal do pró-peptídeo natriurético tipo B e proteína C reativa em comparação a pacientes sem lesão miocárdica. Como fatores independentes, proteína C reativa e contagem de plaquetas foram relacionados com o risco de morte, e neutrófilos e contagem de plaquetas foram relacionados ao risco de suporte ventilatório mecânico invasivo. Os pacientes com níveis elevados de troponina apresentaram um maior risco de morte (RR 2,03, IC95% 1,60-2,58) e suporte ventilatório mecânico (RR 1,87;IC95% 1,57-2,23), em comparação àqueles com níveis de troponina normais. Conclusão Lesão cardíaca foi um preditor independente de mortalidade hospitalar e necessidade de suporte ventilatório mecânico em pacientes hospitalizados com COVID-19.

ABSTRACT: The present study identified virulence genes and pathological changes caused by Escherichia coli in chicken carcasses condemned for airsacculitis and assessed if the histopathological examination and polymerase chain reaction (PCR) were effective for studies like this. Trachea, liver, and lung were collected from 30 chickens with suspected airsacculitis that has been condemned in the inspection line. The samples were analyzed by PCR to simultaneously identify two virulence genes (iss and tsh genes) and for histopathological testing. PCR efficiently genotypically characterize the E. coli isolates, where the virulence genes iss and tsh were found in three birds simultaneously. The histopathological examination detected a predominance of heterophils and mononuclear cells in the trachea (100%), lung (90%), and liver (13.3%). The liver was the organ where practically no alteration was diagnosed. The results of multiplex PCR for the tsh and iss virulence genes indicate the great potential of the approach in the characterization of E. coli isolates. Unspecific identification did not occur, thus making it necessary to use technologies for the identification and prevention of this agent in aviaries and poultry abattoirs.

RESUMO: O objetivo do presente estudo foi identificar genes de virulência e alterações patológicas provocadas por Escherichia coli em carcaças de frango condenadas por aerossaculite e se o exame histopatológico e uma Reação em Cadeia da Polimerase (PCR) são eficazes para os estudos dessa natureza. Para isso, foram coletados traqueia, fígado e pulmão de 30 frangos condenados na linha de inspeção, com suspeita de aerossaculite. As amostras foram submetidas a PCR para a identificação de dois genes de virulência de modo simultâneo (genes iss e tsh) e ao teste histopatológico. A PCR foi eficiente para caracterizar genotipicamente os isolados de E. coli, em que se constatou em três aves os genes de virulência iss e tsh simultaneamente. No exame histopatológico detectou-se a predominância de heterófilos e mononucleares na traqueia 100%, no pulmão 90% e no fígado 13,3%. O fígado foi o órgão onde praticamente não foi diagnosticada nenhuma alteração. Diante dos resultados obtidos, foi possível observar que a PCR multiplex para os genes de virulência tsh e iss apresenta um grande potencial na caracterização de isolados de E. coli, já que não gerou identificação inespecífica, com isso faz-se necessária a utilização de tecnologias para identificação e prevenção desse agente nos aviários e matadouros avícolas.

Abstract: En | Text: En | PDF: En

Developing biomaterials for tissue regeneration is a promising alternative for the recovery of various tissues, including bone. Atorvastatin (ATV) has a series of beneficial effects which includes bone anabolism, vasodilating, and anti-inflammatory actions. The main objective of this work was to produce and characterize polycaprolactone (PCL) matrices incorporated with ATV. Samples were prepared by the solvent casting technique. Scanning electron microscopy (SEM), X-Ray diffraction (XRD), Fourier transform infrared spectrometry (FTIR), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC) and in vitro release studies were performed. FTIR analysis showed that no chemical bonds were formed between PCL and ATV. SEM analysis showed that the amount of ATV affects sample morphology. According to XRD and thermal analysis, the main ATV characteristics were maintained. The studies showed that PCL/ATV samples release the drug in a prolonged way since its release reaches around 50% after 15000 minutes of analysis and the model that showed the best fit for the studied matrices was the Higuchi model, with a correlation coefficient above 0.95.

Abstract Irrigation solutions might affect dentin surface characteristics and, consequently, endodontic sealers adhesion. Objective This study analyzed the effect of different final irrigation protocols on push-out bond strength (BS) of AH Plus to dentin seven days and 20 months after obturation. Scanning electron micrographs were obtained from the dentin surface of one sample/group after final irrigation. Methodology Canals of bovine incisors were instrumented and received final irrigation with (n=21): G1 – 2.5% sodium hypochlorite (NaOCl) + distilled water; G2 – 2.5% NaOCl + 17% EDTA; G3 – 2.5% NaOCl + 17% EDTA + 2.5% NaOCl; G4 – 2.5% NaOCl + 17% EDTA + 2% chlorhexidine (CHX); G5 – mixture 5% NaOCl + 18% etidronate (HEDP); and G6 – mixture 5% NaOCl + 10% tetrasodium EDTA (Na4EDTA). After irrigation, one root/group was split and images were obtained by scanning electron microscopy (SEM). The other 20 roots/group were filled with only AH Plus sealer. Three slices/root were used for push-out assessment seven days and 20 months after obturation. One-way analysis of variance and Tukey (α<0.05) were used to compare the results among experimental groups, and unpaired t-test (α<0.05) was used to compare the results of the same group over time. Results The photomicrographs showed that, excepting G1, all groups completely removed the smear layer from the samples. In G2 and G4, the opening of the dentin tubules enlarged. In G3, erosion was observed in the peritubular and intertubular dentin. Values of the BS in the seven days were G2=G3=G4=G5>G6=G1 and in the 20 months were G3=G5>G6=G4>G1=G2. G3, G5, and G6 presented values of BS in 20 months similar to the values of seven days (P>0.05). Conclusions The final irrigation protocols tested produced dentin surfaces with different characteristics. Only G3 and G5 presented high BS values that were stable over time.

Abstract: Pt | Text: Pt | PDF: Pt

A new material formed by Shiff base (chitosan and ortho-vanillin) and copper were synthesized and characterized by UV-visible, infrared spectroscopies, thermal analysis, elemental analysis, electron microscopy, 1H NMR spectra and electrochemical techniques. In this study, it was possible to identify the formation of Schiff’s base (BS), with a degree of substitution of 42.5% by NMR. The electron microscopy study indicates an amorphous character for BS. The material was used to build an electrode, which proved to be sensitive to the addition of nitrite, making it possible to quantify it. The values obtained for detection limit and limit of quantification of the electrode formed BS-Cu were 0.062 µmol L-1 and 0.21 µmol L-1, respectively.

ABSTRACT Purpose COVID-19 posed numerous challenges to educational programs that had to quickly adapt to remote online learning (ROL) to ensure the continuity of health professional training over the pandemic. We aimed to assess the students' and professors' perceptions of the teaching-learning process in the Physical Therapy, Speech-Language-Hearing Sciences, and Occupational Therapy undergraduate programs at a Brazilian public university. Methods We used an electronic self-reported questionnaire with multiple-choice questions on a Likert scale ranged 1-5; higher the score, higher the level of agreement/importance/satisfaction. Results Most of undergraduate students and teachers had previous experience using information and communication technologies, and 85% stated their preference for in-person learning. Students expressed their appreciation for more active learning methodologies with clear objectives, accessible content, and visualization of abstract concepts. Regarding benefits and barriers, some similar perceptions were observed between students and teachers with ROL favoring time management, benefits in the teaching-learning process, satisfaction and motivation with the course content, and low attendance rates to general academic activities due to absent or poor access to technological resources. Conclusion ROL is an alternative learning mode when the in-person classes cannot be carried out, as in the case of the COVID-19 pandemic. ROL is believed to be unfit to replace in-person learning, although it can complement the traditional classroom-based education in a hybrid model, respecting the nature of each program in the field of health that requires in-person practical training.

RESUMO Objetivo O COVID-19 impôs inúmeros desafios aos programas educacionais que tiveram que se adaptar rapidamente ao aprendizado remoto on-line (ARO) para garantir a continuidade da formação dos profissionais de saúde durante a pandemia. O objetivo do estudo foi avaliar a percepção de alunos e professores sobre o processo ensino-aprendizagem dos cursos de graduação em Fisioterapia, Fonoaudiologia e Terapia Ocupacional de uma universidade pública brasileira. Métodos Foi utilizado um questionário eletrônico autoaplicável com questões de múltipla escolha em escala Likert de 1 a 5; quanto maior a pontuação, maior o nível de concordância/importância/satisfação. Resultados A maioria dos alunos de graduação e professores tinha experiência anterior no uso de tecnologias de informação e comunicação, e 85% afirmaram preferir o ensino presencial. Os alunos expressaram preferência por metodologias de aprendizagem mais ativas, com objetivos claros, conteúdo acessível e visualização de conceitos abstratos. Em relação aos benefícios e barreiras, algumas percepções semelhantes foram observadas entre alunos e professores com ARO favorecendo a gestão do tempo, benefícios no processo ensino-aprendizagem, satisfação e motivação com o conteúdo do curso e baixa frequência às atividades acadêmicas gerais por ausência ou dificuldade de acesso aos recursos tecnológicos. Conclusão O ARO pode ser uma modalidade alternativa de aprendizado quando as aulas presenciais não podem ser realizadas, como no caso da pandemia do COVID-19. Porém, o ARO é inadequado para substituir a aprendizagem presencial, embora possa complementar a educação presencial tradicional em um modelo híbrido, respeitando a natureza de cada programa na área da saúde que exige formação prática presencial.

Abstract Healthcare workers present an increased risk of contagion for the SARS-CoV-2 virus due to their labor exposure. Here, we describe the clinical, laboratory, and immunological characteristics of healthcare workers, before vaccine application, exposed to SARS-CoV-2-infected patients. We collected sociodemographic, clinical, and laboratory information from 50 professionals who worked during the COVID-19 pandemic at the Clinical Hospital of the Northwest in Brazil. The results showed that most workers are women, over 50 years old, and worked as nursing technicians. Approximately 56% of workers were positive for a previous infection by RT-PCR and/or anti-SARS-CoV-2-immunoglobulin tests. Increased levels of hematocrit, neutrophils, NK lymphocytes, and fibrinogen, were found in positive healthcare workers, suggesting a light inflammatory status. The immunological findings showed an increase in IL-17 production and a Th2/Th17/Th22 profile followed by high serology for anti-SARS-CoV-2 IgM and IgG. Those data reveal the importance of studies with healthcare workers to investigate if the continuous exposition to the virus may result in chronic activation of the immune system and/or pulmonary inflammation in this target group.

ABSTRACT Objective To identify eye conditions associated to social distancing and related increase in screen time exposure on children and teenagers. Methods Observational, descriptive and analytical study, with a cross-section design, carried out between July and August 2021, by questionnaire survey. Results Headaches related to excessive screen time exposure were reported by 26.51% of the students surveyed, while 38.8% reported suspect convergence insufficiency. Regarding the questionnaire about dry eye, 18.8% were symptomatic and 7.5% reported hard-to-manage symptoms. Computers were the devices most used for schoolwork (71.5%), followed by cellphones on second place (66.3%). Symptomatic cases of dry eye were mostly reported by participants that did not make use of computers (36.4%). It was not possible to establish a connection between convergence insufficiency and device usage time. Those participants that reported more screen time exposure also reported an increased percentage of hard-to-manage symptoms (42.9%), regarding dry eye. Conclusion Dry eye and convergence insufficiency symptoms were more prevalent in the surveyed population.

RESUMO Objetivo Identificar as alterações oculares em crianças e adolescentes secundárias ao fator do isolamento social e ao consequente aumento do uso de telas. Métodos Estudo observacional, descritivo e analítico, do tipo transversal realizado no período de julho a agosto de 2021, por meio da aplicação de questionários. Resultados Apresentaram cefaleia associada ao uso excessivo de tela 26,51% dos estudantes e 38,8% relataram suspeita de insuficiência de convergência. Em relação ao questionário de olho seco, 18,8% foram sintomáticos e 7,5% sintomáticos de difícil manejo. O computador foi o dispositivo mais utilizado em atividades escolares (71,5%), e, em segundo lugar, esteve o celular (66,3%). Casos sintomáticos de olho seco foram mais relatados em participantes que não faziam uso de computador (36,4%). Não foi possível identificar relação entre insuficiência de convergência e tempo de uso de dispositivos. Em relação ao olho seco, aqueles que passaram mais tempo em frente a tela relataram maior porcentagem de sintomas de difícil manejo (42,9%). Conclusão Foram mais prevalentes olho seco e sintomas de insuficiência de convergência na população estudada.
