ABSTRACT Wild birds have great prominence in the transmission of diseases to humans, mainly due to their ease of access to human populations, raising concerns about the potential impact of that proximity on public health. The present study reports ARV and PBV occurrence in wild birds from an environmental protection area in the Amazon biome, in Pará state, Brazil. We obtained 155 fecal specimens from 47 species of wild birds for RNA extraction, ARV and PBV detection utilizing molecular methods, nucleotide sequencing, and phylogenetic analysis. ARV prevalence was 0.6% (1/155), being positive in an individual of Myrmotherula longipennis, and PBV prevalence was 1.29% (2/155), affecting two individuals of Guira guira. The PBV strains were assigned to genogroup I based on phylogenetic analysis, and they shared a strong phylogenetic link with strains isolated from different geographic locations. The ARV strain was more closely related to strains that had previously circulated in the same region. The presence of ARV and PBV in this habitat suggests that infection cycles of these agents occur naturally in the wild ecosystem, potentially triggering transmission events between bird species and humans. This is the first study on ARV detection in wild birds in Brazil and the first report on the occurrence of PBV in wild Guira guira. Additional studies are required to determine the epidemiology, origin, evolution, and emergence of new potentially pathogenic viruses in the Amazon.

RESUMO As aves silvestres têm grande destaque na transmissão de doenças ao homem, principalmente pela facilidade de acesso à população humana, levantando preocupações sobre o potencial impacto dessa proximidade no contexto da saúde pública. O presente estudo relata a ocorrência de ARV e PBV em aves silvestres de uma área de proteção ambiental no bioma Amazônico. Obtivemos 155 espécimes fecais de 47 espécies de aves silvestres, que foram submetidos a extração de RNA, detecção de ARV e PBV por técnicas moleculares, sequenciamento nucleotídico e análise filogenética. A prevalência de infecção por ARV foi 0,6% (1/155), sendo positivo em um indivíduo de Myrmotherula longipennis, e a prevalência de PBV foi 1,29% (2/155), afetando dois insdivíduos de Guira guira. A análise filogenética agrupou as cepas de PBV no genogrupo I, mostrando intensa relação filogenética com cepas isoladas de outras regiões geográficas. A cepa de ARV esteve mais relacionada filogeneticamente a cepas previamente circulantes na mesma região. Este é o primeiro estudo sobre detecção de ARV em aves silvestres no Brasil e o primeiro relato sobre a ocorrência de PBV em Guira guira. A circulação de ARV e PBV nesse ambiente demonstra que os ciclos desses agentes estão ocorrendo de forma natural no ecossistema silvestre, o que pode desencadear possíveis eventos de transmissão entre as espécies aviárias e humanos. Estudos adicionais são necessários para determinar a epidemiologia, origem, evolução e surgimento de novos vírus potencialmente patogênicos na Amazônia.

ABSTRACT Purpose: To evaluate the quality of life and stress level related to visual function following pediatric cataract surgery in a Brazilian public hospital. Methods: This prospective study analyzed children aged 6-14 years old who underwent cataract surgery. The Childhood Stress Scale and Children’s Visual Function Questionnaire (CVFQ) were used to assess stress levels and quality of life, respectively. Both instruments were applied by two psychologists before and after the surgery. Eye examination was performed by two ophthalmologists. Preoperative and postoperative data were compared. Results: In total, 23 children (32 eyes) were enrolled in the study, of which 9 had bilateral cataracts. The average age group at the time of surgery was 9.65 ± 2.26 (6-14) years old. One month after the surgery, the spherical equivalent was -0.90 ± 1.66D, and the corrected distance visual acuity was 0.13 ± 0.10 (0-0.3) LogMAR in bilateral cases and 0.50 ± 0.39 (0-1.3) LogMAR in unilateral cases (p<0.01). According to the Childhood Stress Scale, 77.7% of the bilateral cases and 57.1% of the unilateral cases had stable stress levels, and 34.7% of the children improved their stress level. The analysis of the CVFQ was based on scores for general health, general vision health, competence, personality, and treatment. After cataract surgery, 78.2% of the patients had improved or maintained CVFQ scores in the general health domain; 82.6%, general vision health; 95.6%, competence; 56.5%, personality; and 78.2%, treatment. Conclusion: Pediatric cataract surgery improves the visual function and the quality of life even in patients undergoing surgical procedures, without increasing the stress levels.

Conclusão: A cirurgia de catarata pediátrica melhora a função visual e a qualidade de vida em pacientes submetidos a procedimento cirúrgico, sem aumentar o nível de estresse.

Reuse made by the separation of whey can reduce the waste of human milk. However, the authors are not aware of the literature on treatments in human whey, made available by pasteurization holder, freeze-drying, spray drying, and high hydrostatic pressure. In this context, the present study applied treatments to human whey and evaluated their lipid and immunological quality. Among the results, a different formation in the triacylglycerol profile was evidenced after the application of spray drying and high hydrostatic pressure, while pasteurization and freeze-drying presented ion intensity close to the control human whey. In addition, pasteurization proved to be adequate for lipid nutritional quality and transformation factor-β1 (TGF-β1) concentration, while an increase in interleukin-10 (IL-10) levels was promoted, between 73 and 80%, after freeze-drying, spray drying, and high hydrostatic pressure. Through the principal component analysis, it is noteworthy that the processes presented divergences in terms of the effects caused, with similarity only between pasteurization and freeze-drying in the composition of fatty acids. However, it was observed that all processes were able to maintain the nutrients. Nevertheless, it is relevant to consider individual characteristics presented and the interest in the desired quality, which can be promising as a complementary product to infant feeding.

Abstract Objectives: Evaluation of the repeatability of occlusal registration performed with the T-scan in the same individual on two different days. Methods: A calibrated operator performed 46 measurements on 23 volunteers, with a time interval of seven days using the T-scan (v.9). Maximum intercuspation and maximum force values were assessed by tooth and individual. The repeatability of the device was determined by the mean of the intraclass correlation coefficient. The results were presented as mean +/- 95% confidence interval, and the data analysis was performed using SPSS software. Results: Significant differences were found in teeth 12 and 11 in maximum force and teeth 13, 12, and 11 in maximum intercuspation (p<0.05). The two measurements performed showed a high intraclass correlation coefficient value, both for maximum intercuspation and for maximum force (99.5% [99.4, 99.6] and 97.9% [97.5, 98.2]), respectively. Conclusions: The results obtained in this study suggest that the T-scan can be considered a complementary means for occlusal diagnosis and that these measurements show high intra-individual repeatability over time.

Resumo Objetivos: Avaliar a repetibilidade intra-indivíduo do registo oclusal realizado com o T-scan em dois momentos temporais. Métodos: Foram avaliados 23 voluntários com 46 medições com o T-scan (v.9) por um operador calibrado, com um intervalo de tempo de sete dias. Avaliaram-se os valores em intercuspidação e força máxima total e por dente, em cada indivíduo. A repetibilidade do aparelho foi determinada através do coeficiente de correlação intraclasse. Os resultados foram apresentados como média +/- intervalo de confiança a 95% e a sua análise realizada com recurso ao software SPSS. Resultados: Foram detetadas diferenças significativas entre medições nos dentes 12 e 11 em forç,a máxima de mordida e 13, 12 e 11 em intercuspidação máxima entre a primeira e segunda avaliações (p<0,05). Os dois momentos temporais apresentaram um coeficiente de correlação intraclasse elevado tanto para a intercuspidação máxima como para a força máxima de mordida, com valores de 99,5% [99,4; 99,6] e 97,9% [97,5; 98,2], respetivamente. Conclusões: Os resultados obtidos neste estudo sugerem que o T-scan poderá ser considerado um meio complementar de diagnóstico oclusal e que as medições apresentam uma elevada repetibilidade intra-indivíduo.

ABSTRACT Pembrolizumab is an immune checkpoint inhibitor used as a cancer therapy. The incidence of immune related adverse events in patients receiving immune checkpoint inhibitors can be as high as 59%-85. Renal adverse effects are uncommon, but the incidence of kidney toxicity related to pembrolizumab is rising as the use of this agent becomes more frequent. We present an uncommon case of biopsy-proven acute interstitial nephritis secondary to pembrolizumab in a patient with metastatic squamous cell carcinoma at the time of his fourth scheduled cycle. Despite the good initial tumor response, pembrolizumab had to be suspended and the patient started on corticosteroids with an initial good response. On his own initiative, the patient stopped prednisolone early, leading to a rebound acute kidney injury. Pembrolizumab was not reintroduced for the risk of further renal function worsening. His clinical status declined due to the progression of the neoplastic disease, and he was referred for palliative care. This case illustrates the importance of systematizing some key points in the approach to acute interstitial nephritis secondary to pembrolizumab: the role of the differential diagnosis of acute kidney injury in a patient under an immune checkpoint inhibitor, the role of glucocorticoids and the controversy about rechallenging this drug after a related acute interstitial nephritis.

Abstract Pituitary apoplexy refers to a rare clinical syndrome consisting of signs and symptoms that occur due to rapid expansion of the contents of the sella turcica. It can occur spontaneously or associated with pituitary tumors. It can have a broad clinical spectrum, but usually presents with severe headache, visual impairment and hypopituitarism. Sudden onset of symptoms associated to imagiologic confirmation makes the diagnosis. Surgical treatment is advised when there is important compression of the optic tract. We present a case report and a review of the literature on pituitary apoplexy in pregnancy. The cases were reviewed to obtain information on maternal characteristics, clinical presentation, diagnostic studies, therapeutic modalities and maternal and fetal outcomes. Our review found 36 cases of pituitary apoplexy in pregnancy. Most of the cases occurred in the second trimester of pregnancy and headache was the most frequent symptom at presentation. Surgical therapy was required in more than half of the patients. In what respect maternal and fetal outcomes, there were 3 cases of preterm delivery and one case of maternal death. Our clinical case and literature review reinforces the importance of an early diagnosis to avoid potential adverse consequences.

Abstract BACKGROUND: The fibromyalgia impact questionnaire (FIQ) relates to the functional capacity, professional situation, psychological disorders, and physical symptoms, and can identify the factors that determine the impact of the syndrome and characteristics of its carriers; the higher the score, the greater the impact of fibromyalgia on the quality of life. OBJECTIVE: To evaluate the impact of fibromyalgia on the quality of life of individuals with fibromyalgia, who were categorized according to the FIQ during the coronavirus disease pandemic. DESIGN AND SETTING: A cross-sectional study was conducted at an institution of higher education in Taquara, RS, Brazil. METHODS: A quantitative study was carried out, with the application of a sociodemographic and clinical questionnaire, and the FIQ in 163 Brazilian individuals with a medical diagnosis of fibromyalgia. Data were collected using SurveyMonkey software. RESULTS: Of the female carriers, 98.2% were living in urban areas, working, and under pharmacological and complementary treatment. The FIQ results showed that seven of the 10 items had the maximum score. The items “physical function” and “feel good” had intermediate scores, and the item “missed work” had a low score. The average total score was 79.9 points, indicating that fibromyalgia had a severe impact on the participants’ lives. A severe impact of fibromyalgia was observed in 61.3% of the participants, a moderate impact in 30.7%, and a low impact in 8%. CONCLUSION: The survey findings suggest a severe impact in the majority of the Brazilian fibromyalgic population.

Abstract Background and Aim: Aeromonas are Gram-negative rods known to cause a spectrum of diseases. Inflammatory bowel disease (IBD) is an idiopathic complex condition resulting from interaction of multiple factors. Aeromonas infection in association with IBD is still largely unknown. We aim to look for the significance of Aeromonas infection and for significant differences between IBD and non-IBD patients. Methods: A retrospective observational analysis was performed of all patients positive for Aeromonas in stool cultures, during a 10-year period, from a tertiary and university hospital. Results: Fifty patients were included, 56% male with a mean age of 42.1 years. Thirty-eight (76%) were non-IBD and 12 (24%) IBD patients. IBD patients were more frequently under immunosuppressors. Two patients were asymptomatic and 44% developed mild, 44% moderate, and 16.7% severe infection. The main strains isolated were Aeromonas hydrophila/caviae. Bacterial co-isolation was found in 4 non-IBD and histological findings of cytomegalovirus in 2 IBD patients. Non-IBD patients presented more frequently with fever and IBD patients with bloody diarrhea and abdominal pain. There was higher tendency for severe infection rate in IBD patients with higher antimicrobial therapy use. Steroids were exclusively used in the IBD group. From IBD, 4 patients had the diagnosis of ulcerative colitis and 9 of Crohn’s disease with colonic involvement. Of these patients, 5 received IBD diagnosis after the acute episode of Aeromonas infection. Conclusions: Clinical presentation of Aeromonas infection differs between IBD and non-IBD patients. Non-IBD patients had milder severity of infection with less use of antibiotics. Aeromonas infection seems to greatly contribute to IBD manifestation.

Resumo Introdução: A etiologia da Doença Inflamatória Intestinal (DII) é complexa e resultante da interação de diversos fatores, nomeadamente microbiológicos. A infeção por Aeromonas caracteriza-se por um espectro alargado de manifestações clínicas. O papel da infeção por Aeromonas na DII não está caracterizado. Objetivos: Avaliar o significado da infeção por Aeromonas na DII e as diferenças com a infeção em doentes não-DII. Métodos: avaliação retrospetiva e observacional de todos os doentes com isolamento microbiológico de Aeromonas em amostras fecais num período de 10 anos, num hospital terciário. Resultados: foram avaliados 50 doentes, 56% do sexo masculino, com idade média de 42.1 anos. Doze (24%) com diagnóstico de DII e trinta e oito (76%) não-DII. Os doentes com DII encontravam-se mais frequentemente sob imunossupressão. Dois doentes foram assintomáticos, 44% desenvolveram doença ligeira, 44% moderada e 16.7%severa, havendo maior tendência para infeção severa nos DII. Os doentes não-DII apresentaram mais frequentemente febre e os DII diarreia sanguinolenta e dor abdominal. O uso de antimicrobianos foi superior no grupo DII e a utilização de corticoesteroides foi exclusiva nestes doentes. Isolamento concomitante de outros agentes microbiológicos ocorreu em 4 doentes não-DII e 2 com DII tinham histologia compatível com infeção por Citomega-lovírus. Da população DII, 4 eram Colite Ulcerosa e 9 Doença de Crohn com envolvimento cólico. Destes, 5 receberam o diagnóstico após a infeção por Aeromonas. Conclusão: A apresentação clínica da infeção por Aeromonas foi distinta entre as populações DII e não-DII, sendo que os doentes DII apresentaram doença mais severa e maior utilização de antimicrobianos. A infeção na DII ocorreu essencialmente em doentes com envolvimento cólico.

Abstract Objectives: The aim of this study is to develop and validate a novel clinical report form in the format of a structured interview to enable the characterization of the Portuguese population of the Baixo Vouga region with different subtypes of nodular thyroid pathologies (NTyPs). Materials and methods: A structured interview was developed and to the best of our knowledge, this is the first structured interview built and validated for that purpose in Portugal. Results: This structured interview enables the identification of possible correlations between each subtype of nodular lesions and sociodemographic data, consumption habits and lifestyle, endocrine history, and family predisposition. Conclusion: The novel structured interview will simultaneously, enable a detailed characterization of the group of patients with nodular thyroid lesions and will support future metabolomic studies.

The composition of human milk (HM) includes changes under the influence of factors such as genetics, stage of lactation, time of day, and even breastfeeding time. However, the authors are not aware of studies that evaluated the influence of breastfeeding time on fatty acid composition and cytokine. Thus, the objective of this study was to evaluate the influence of breastfeeding time (previous, intermediate, posterior milk) on kilocalorie concentration, fatty acid (FA) composition, and concentration of the cytokines interleukin-10 (IL-10), interferon factors for necrotic tumor (TNF-α) in HM colostrum. The results showed that the concentration of kilocalories was higher in posterior milk than in the previous, the composition of the main fatty acids found in the samples was influenced by the breastfeeding time, and the concentration of IL-10 and TNF-α was influenced in all samples with exception to mother 2. The principal component analysis explained 71% of the variances in the results. Thus, we concluded that the breastfeeding time is a factor that influences the concentration of kilocalories, and if it is necessary to use a more caloric milk, it is recommended to use the posterior milk; the FAs composition and the evaluated cytokines were also influenced by the breastfeeding time.

Abstract This study is framed within the context of Brazil’s health reform by proposing a pedagogy for professional training for the Brazilian National Health System (SUS) based on the theories of Paulo Freire and Dermeval Saviani. We conducted a theoretical study drawing on historical and dialectical materialism. In the first moment (thesis), emphasis is given to the empirical, based on reality. In the second moment (antithesis), we draw on the theories of Freire and Saviani focusing on the categories work, conscience and language. In the third moment (synthesis), the concrete is attained through the categories knowledge/content, method and teaching-learning processes. As part of the synthesis, we propose a pedagogy for professional training for the SUS structured around three core elements: basis, method and purpose. It is proposed that the pedagogies of Freire and Saviani provide the underpinnings for a pedagogy for professional training for the SUS.

ABSTRACT The attempt to face the limitations of wood-based materials, especially concerning the relationship with water, is still a considerable gap in research on this subject. The present work proposes the accomplishment of thermal treatment in fiberboard-type hardboard, using different temperatures and times, to evaluate the effect on the physical-mechanical properties. The parameters of the heat treatment were temperatures of 120 and 160 °C and times of 20 and 40 min. The hardboards were individually heat treated in a kiln. The characterization was performed from physical tests such as bulk density, moisture content, water absorption (2 and 24 h), thickness swelling (2 and 24 h); and mechanical properties of flexural strength. The treatment with a temperature of 160 °C for 40 min showed the lowest values of water absorption in 24 h (34%). Thickness swelling was lower compared to control, for all the treatments applied. Regarding flexural strength, the treatment that adopted the 160 °C for 20 min showed the highest MOR value (26.3 MPa). In general, the performance of heat treatments positively influenced the physical and mechanical properties of the hardboards, being an interesting alternative in the development of products for applications in internal environments.
