This work aimed to analyze the Sickle Cell Anemia (SCA) approach in Natural Sciences textbook collections approved in 2021 National Textbook and Teaching Material Program (PNLD) for High School. The focus of these analyses was: the racial discourse associated with SCA and scientific racism; health approaches; and adequacy from a clinical-scientific point of view. To this end, the content analysis proposed by Bardin was adopted, involving textbooks floating reading, the creation or adaptation of categories and indicators for analysis, the material description and the interpreting the data collected. The data was compared with previous analyses of the approach to SCA in biology textbooks from the 2012 and 2015 PNLD. The approach to SCA, when it did occur in the current collections, was linked to natural selection, without focusing on racial issues, and based on a molecular description. There was a silencing of the approach to SCA in relation to the findings of previous research. In addition, biomedical and reductionist approaches to SCA continued to predominate, disregarding socio-political and historical aspects related to the disease.

El objetivo de este estudio fue analizar el abordaje de la Anemia Falciforme (AF) en las colecciones de Ciencias Naturales y sus Tecnologías aprobadas en el Programa Nacional de Libros de Texto y Material Didáctico (PNLD) 2021 para la enseñanza media. El foco de ese análisis fue: el discurso racial asociado a la Anemia Falciforme y el racismo científico; los abordajes de salud; y la adecuación del punto de vista clínico-científico. Para ello, se adoptó el análisis de contenido propuesto por Bardin, que implica la lectura flotante de las colecciones, la creación o adaptación de categorías e indicadores para el análisis, la descripción del material y la interpretación de los datos. Los datos se compararon con análisis anteriores sobre el abordaje de la AF en los libros de texto de biología de los PNLD de 2012 y 2015. La aproximación a la AF, cuando se producía en las colecciones actuales, estaba vinculada a la selección natural, sin centrarse en cuestiones raciales, y basada en una descripción molecular. Hubo un silenciamiento del abordaje de la AF en relación a los hallazgos de investigaciones anteriores. Además, siguieron predominando los enfoques biomédicos y reduccionistas de la AF, sin tener en cuenta los aspectos sociopolíticos e históricos relacionados con la enfermedad.

Este trabalho objetivou analisar a abordagem sobre a Anemia Falciforme (AF) nas coleções de Ciências da Natureza e Suas Tecnologias aprovadas no Programa Nacional do Livro e do Material Didático (PNLD) de 2021 para o Ensino Médio. Os focos desta análise foram: o discurso racial associado a AF e ao racismo científico; as abordagens de saúde; e a adequação do ponto de vista clínico-científico. Para tanto, adotou-se a análise de conteúdo proposta por Bardin, envolvendo a leitura flutuante das coleções, a criação ou a adaptação de categorias e indicadores para análise, a descrição do material e a interpretação dos dados. Os dados foram comparados com análises anteriores sobre a abordagem da AF em livros didáticos de biologia do PNLD de 2012 e de 2015. A abordagem da AF, quando ocorreu nas coleções atuais, esteve atrelada a seleção natural, sem pautar questões raciais, e a partir de uma descrição molecular. Observou-se um silenciamento na abordagem sobre a AF em relação aos achados de pesquisas anteriores. Além disso, manteve-se a predominância de abordagens biomédicas e reducionistas sobre a AF, desconsiderando aspectos sociopolíticos e históricos relacionados a doença.

Abstract Background: Only a fraction of patients with cutaneous lupus erythematosus (CLE) will eventually progress toward systemic disease (SLE). Objective: To find inflammatory biomarkers which could predict the progression of cutaneous lupus erythematosus (CLE) into systemic lupus erythematosus (SLE) using immunohistochemical (IHC) assays. Methods: Immunohistochemical markers for cytotoxic, inflammatory, and anti-inflammatory responses and morphometric methods were applied to routine paraffin sections of skin biopsies, taken from lesions of 59 patients with discoid lupus, subacute lupus, and lupus tumidus. For the diagnosis of SLE, patients were classified by both the American College of Rheumatology (ACR-82) and the Systemic Lupus International Collaborating Clinics (SLICC-12) systems. Results: Skin samples from CLE/SLE +patients presented higher expression of IL-1β (ARC-82: p = 0.024; SLICC-12: p = 0.0143) and a significantly higher number of cells marked with granzyme B and perforin (ARC: p = 0.0097; SLICC-12: p = 0.0148). Biopsies from CLE/SLE- individuals had higher expression of IL-17 (ARC-82: p = 0.0003; SLICC-12: p = 0.0351) and presented a positive correlation between the density of granzyme A+and FoxP3+ cells (ARC-82: p = 0.0257; SLICC-12: p = 0.0285) and CD8+ cells (ARC-82: p = 0.0075; SLICC-12: p = 0.0102), as well as between granulysin-positive and CD8+ cells (ARC-82: p = 0.0024; SLICC-12: p = 0.0116). Study limitations: Patients were evaluated at a specific point in their evolution and according to the presence or not of systemic disease. The authors cannot predict how many more, from each group, would have evolved towards SLE in the following years. Conclusions: In this cohort, immunohistochemical findings suggested that patients with a tendency to systemic disease will show strong reactivity for IL-1β, while those with purely cutaneous involvement will tend to express IL-17 more intensely.

Abstract Background: One of the main adverse reactions of adjuvant radiotherapy for breast cancer is radiodermatitis. Objective: To assess the incidence of radiodermatitis in women with breast cancer, identify factors associated with its severity and determine the time at which this event occurs. Methods: Prospective cohort study in 113 women with breast cancer who were evaluated before radiotherapy and at every fifth session until the end of treatment. Logistic regression and Cox proportional regression model were used for the assessment of risk factors; P values < 0.05 were considered significant. Results: The incidence rate of radiodermatitis was 98.2% and it was demonstrated that for each additional point of the Body Mass Index (BMI), the chance of occurrence of grades II to IV radiodermatitis increases by 14% (OR = 1.14 [95% CI 1.04–1.26]; p = 0.004) and statin use increases the risk of more severe skin lesions by four-fold (OR = 4.27 [95% CI 1.11–16.42]; p = 0.035). The exclusive use of hydrogel for skin hydration was an independent factor in delaying the onset of radiodermatitis (HR = 0.55 [95% CI 0.36–0.82]; p = 0.004). Study limitations: The main limitation of this study was its external validity. The identified factors should be considered for services and populations similar to those in this study. Conclusions: There was a high incidence of radiodermatitis and its severity was related to higher BMI, statin use; there was a protective effect of hydrogel use.

Resumo Este estudo avaliou o efeito do óleo volátil de Alpinia zerumbet (OVAz) na expressão do gene da caveolina-1 e na fibrose muscular. Os ratos foram imobilizados para induzir a fibrose do músculo gastrocnêmio, e foram tratados com OVAz. A qualidade do colágeno foi avaliada com histologia e à expressão do gene caveolina-1 (CAV-1) foi avaliada usando qPCR. A análise histomorfológica indicou uma redução significativa no perímetro, largura e intensidade do colágeno nos grupos tratados. Os resultados dos níveis de expressão sugeriram diminuição nos grupos de lesão e em dois grupos de tratamento (0,0115 µg/g e 0,009 µg/g). No entanto, com a menor concentração (0,0065 µg/g), não foi observada diferença significativa, apresentando níveis semelhantes aos encontrados em tecido saudável. O uso do OVAz foi eficaz para reverter as alterações do colágeno causadas pela fibrose, e sua menor concentração apresentou uma possível tendência de aumento na expressão do CAV-1. Portanto, os resultados mostraram que o OVAz tem potencial para ser uma alternativa não invasiva e de baixo custo para auxiliar no tratamento da fibrose muscular.

Abstract This study evaluated the effect of the volatile oil of Alpinia zerumbet (VOAz) on caveolin-1 gene expression and muscular fibrosis. The rats were immobilized to induce fibrosis of the gastrocnemius muscle, and they were treated with VOAz. Collagen quality was assessed by histology and the expression of the caveolin-1 (CAV-1) gene was evaluated using qPCR. Histomorphological analysis indicated a significant reduction in the perimeter, width, and intensity of collagen in the treated groups, thus showing that the oil was effective in regulating the quality of collagen at the three concentrations. The results of expression levels suggested a decrease in the lesioned group and in two treatment groups (0.0115 µg/g and 0.009 µg/g). However, with the lowest concentration (0.0065 µg/g), no significant difference was observed, with levels similar to those found in healthy tissue. Therefore, the results showed that VOAz has the potential to be a non-invasive and low-cost alternative to aid in the treatment of muscular fibrosis.

Resumo A lagarta-do-cartucho (Spodoptera frugiperda) é a principal espécie que causa danos à cultura do milho no Brasil. Na perspectiva de estudar alternativas de controle desta praga que preservem os inimigos naturais, o objetivo desta pesquisa foi avaliar a eficiência inseticida dos óleos essenciais de Vanillosmopsis arborea e Lippia microphylla sobre S. frugiperda e verificar a seletividade ao predador Euborellia annulipes. Os bioensaios foram realizados no Laboratório de Entomologia Agropecuária da Universidade Federal da Paraíba, utilizando insetos, de 3º instar de S. frugiperda e E. annulipes, oriundos de criação massal no próprio laboratório. As diluições dos óleos foram realizadas em Tween® 80 nas concentrações de 0, 100, 150 e 200 mg mL-1. 1,0 μL de cada diluição foi aplicado na região protorácica dos insetos. A mortalidade de S. frugiperda foi verificada pelo contato tópico do óleo de V. arborea com LC10 = 74,3 mg mL-1 e LC50 = 172,86 mg mL-1, para L. microphyla, LC10 = 51,26 mg mL-1 e LC50 = 104,52 mg mL-1. As concentrações letais observadas para E. annulipes foram V. arborea LC10 = 71,3 mg mL-1 e LC50 = 160,2 mg mL-1. Enquanto L. microphyla, foram LC10 = 50,3 mg mL-1 e LC50 = 134,67 mg mL-1. Os óleos essenciais de V. arborea e L. microphylla são eficientes no controle de S. frugiperda, mas não são seletivos ao predador E. Annulipes.

Abstract Fall armyworm (Spodoptera frugiperda) is the main species that causes damage to the maize crop in Brazil. In the perspective of studying alternatives of control of this pest that preserve the natural enemies, the aim of this research was to evaluate the insecticidal efficiency of the essential oils of Vanillosmopsis arborea and Lippia microphylla on S. frugiperda and verify the selectivity to the predator Euborellia annulipes. The bioassays were carried out in the Agricultural Entomology Laboratory of the Federal University of Paraiba, using insects, from 3rd instar of S. frugiperda and E. annulipes, originating from mass rearing in the laboratory itself. Dilutions of the oils were performed in Tween® 80 at concentrations of 0, 100, 150 and 200 mg mL-1. 1.0 μL from each dilution was applied to the prothoracic region of the insects. The S. frugiperda mortality was verified by topical contact of V. arborea oil with LC10 = 74.3 mg mL-1 and LC50 = 172.86 mg mL-1, for L. microphyla, LC10 = 51.26 mg mL-1 and LC50 = 104.52 mg mL-1. The observed lethal concentrations for E. annulipes were V. arborea LC10 = 71.3 mg mL-1 and LC50 = 160.2 mg mL-1. While L. microphyla, were LC10 = 50.3 mg mL-1 and LC50 = 134.67 mg mL-1. The essential oils of V. arborea and L. microphylla are efficient in the control of S. frugiperda, but are not selective to the predator E. Annulipes.

Abstract Introduction Complications arising from hospitalization due to COVID-19 have great impact on the physical health of individuals. One of the consequences that deserves attention is muscle weakness, which can be influenced by several factors, generating consequences that may need rehabilitation. Objective To relate the degree of peripheral and respiratory muscle strength to sociodemographic, clinical, and hospitalization variables close to discharge after hospitalization due to COVID-19. Methods This cross-sectional study analyzed data for 52 patients hospitalized for COVID-19 who were interviewed close to discharge to determine sociodemographic and clinical profiles and underwent muscle strength testing. Peripheral muscle strength was evaluated using the Medical Research Council scale, and respiratory strength was determined according to maximum inspiratory and expiratory pressure measured with a vacuometer. Hospitalization data were collected from patient medical records. Results Peripheral strength was reduced in 53.9% of the sample, and the related variables (p < 0.05) were age, weight, cancer, high blood pressure, physical therapy, and number of physiotherapy sessions. Inspiratory force was reduced by 50% of individuals and expiratory force in 60% individuals, and these reductions were related (p < 0.05) to sex, high blood pressure, age, and weight. Conclusion Close to COVID-19 hospital discharge, over 50% of patients exhibited peripheral and respiratory muscle weakness, associated with advanced age, hypertension, and low weight. Those with peripheral weakness received more physiotherapy and had more oncological diseases, while respiratory weakness was more common in men. This underscores the importance of preventive measures and post-hospitalization rehabili-tation programs, including physiotherapy, for muscle strength recovery.

Resumo Introdução As complicações decorrentes da hospitalização por COVID-19 têm grande impacto na saúde física dos indivíduos. Uma das consequências que merece atenção é a fraqueza muscular, que pode ser influenciada por diversos fatores, ge-rando consequências que podem necessitar de reabilitação. Objetivo Relacionar o grau de força muscular periférica e respiratória com variáveis sociodemográficas, clínicas e de internação próximo à alta após internação por COVID-19. Métodos Este estudo transversal analisou dados de 52 pa-cientes hospitalizados por COVID-19 que foram entrevistados próximo à alta para determinar perfis sociodemográficos e clínicos e que foram submetidos a testes de força muscular. A força muscular periférica foi avaliada pela escala do Medical Research Council, e a força respiratória foi determinada de acordo com a pressão inspiratória e expiratória máxima medida com vacuômetro. Os dados de internação foram coletados dos prontuários dos pacientes. Resultados A força periférica esteve reduzida em 53,9% da amostra e as variáveis relacionadas (p < 0,05) foram idade, peso, câncer, hipertensão, fisioterapia e número de sessões de fisioterapia. A força inspiratória foi reduzida em 50% dos indivíduos e a força expiratória em 60% dos indivíduos, e essas reduções foram relacionadas (p < 0,05) ao sexo, pressão arterial elevada, idade e peso. Conclusão Próximo à alta hospitalar da COVID-19, mais de 50% dos pacien-tes apresentavam fraqueza muscular periférica e respiratória associada à idade avançada, hipertensão e baixo peso. Aqueles com fraqueza periférica receberam mais fisioterapia e tiveram mais doenças oncológicas, enquanto a fraqueza respiratória foi mais comum em homens. Isto ressalta a importância de medidas preventivas e programas de reabilitação pós-hospitalização, incluindo fisioterapia, para a recuperação da força muscular.

ABSTRACT This study aimed to determine the antibiotic profile of microorganisms isolated from urine samples of patients with community urine tract infections (UTI) admitted to the University Hospital of the Federal University of Sao Carlos to support an appropriate local empirical treatment. A retrospective cross-sectional study was conducted from October 2018 to October 2020. Data from 1,528 positive urine cultures for bacterial pathogens and antibiograms were tabulated. Bacterial species prevalence and their resistance profile were analyzed and compared by sex and age. For Gram-negative fermenting bacteria, resistance rates were compared between patients with previous hospitalization and the total of infections caused by this group. For comparisons, the Chi-square test was performed, using Fisher’s exact test when necessary (BioEstat program, adopting p ≤ 0.05). A multivariate analysis was applied to assess the effect of the studied variables in predicting multidrug resistance. Infections were more prevalent in women and older adults. Gram-negative bacteria represented 90.44% of total cultures. In both sexes, E. coli prevalence was significantly higher in adults compared with older adults (p < 0.0001). For several antibiotics, resistance rates were higher in the older adults compared with other ages and in patients with Gram-negative fermenting infections and previous hospitalization compared with the total of infections by this group of bacteria. The closer to the hospitalization, the higher the number of antibiotics with superior resistance rates. Resistance rates for aminoglycosides, carbapenems, ceftazidime, nitrofurantoin, piperacillin+tazobactam, and fosfomycin were less than 20%, considered adequate for empirical treatment. Only hospitalization in the previous 90 days was statistically significant in predicting infections by multidrug-resistant bacteria.

ABSTRACT Cassava bacterial blight (CBB), caused by Xanthomonas phaseoli pv. manihotis, is one of the most important diseases affecting cassava production worldwide, including regions of Brazil in the eastern Amazon. The use of beneficial microorganisms, such as endophytic plant growth-promoting bacteria, has emerged as an effective tool for controlling diseases in many crops. Here, two Klebsiella endophytic isolates (26Y and 29Y) isolated from cassava were evaluated for the control of CBB through antagonistic assays and biological control of the disease in plants inoculated by irrigating the substrate and by foliar spray under greenhouse conditions. The two isolates were able to inhibit the in vitro growth of the pathogen, as well as to control the disease severity by at least 90% in plants inoculated by both inoculation methods. We report the first Klebsiella strains to control CBB in the eastern Amazon, though their risk assessment for drug-resistance in humans is still pending.

RESUMO A bacteriose da mandioca, causada por Xanthomonas phaseoli pv. manihotis, é uma das doenças mais importantes que afetam a produção de mandioca no mundo, incluindo a Amazônia Oriental brasileira. O uso de microrganismos benéficos, como bactérias endofíticas promotoras de crescimento de plantas, é uma ferramenta eficaz no controle de doenças de muitas culturas. Nesse estudo, dois isolados endofíticos de Klebsiella (26Y e 29Y) obtidos de mandioca foram avaliados para o controle da bacteriose da mandioca, por meio de ensaios antagônicos e controle biológico da doença em plantas inoculadas por irrigação do substrato e pulverização foliar em condições de casa de vegetação. Os dois isolados inibiram o crescimento in vitro do patógeno, e controlaram pelo menos 90% da severidade da doença em plantas inoculadas por ambos métodos de inoculação. Reportamos as primeiras cepas de Klebsiella a controlar a bacteriose da mandioca na Amazônia Oriental, embora sua avaliação de risco para resistência a drogas em humanos ainda esteja pendente.

ABSTRACT This study presents a new orchid species of the genus Catasetum belonging to the group of species with symmetrical and parallel antennae. It was found in terra-firme and floodplain forests in the Brazilian states of Amazonas and Pará. We provide a formal description of the new species, images, and notes on distribution, habitat, phenology, flower visitors and preliminary conservation status. We compare it with C. cristatum and C. barbatum, both sympatric and morphologically most similar to the new species. It was preliminarily classified in the Endangered (EN) category according to IUCN criteria based on the extent of occurrence, area of occupation, number of occurrence locations and the risks that the known populations are exposed to (deforestation and predatory collection).

Foi encontrada em florestas de terra-firme e igapó nos estados do Amazonas e Pará, Brasil. Fornecemos uma descrição formal da nova espécie, imagens e comentários referentes à distribuição, habitat, fenologia, visitantes florais e estatus de conservação. A comparamos com C. cristatum e C. barbatum, que ocorrem em simpatria e são morfologicamente mais semelhantes à nova espécie. Ela foi preliminarmente classificada na categoria Em Perigo (EN) segundo os critérios da UICN, com base na extensão de ocorrência, área de ocupação, número de localidades de ocorrência e os riscos a que as populações conhecidas estão expostas (desmatamento e coleta predatória).

ABSTRACT Tuberculosis stands as one of humanity’s oldest afflictions, intrinsically intertwined with social disparities. This formidable disease spares no age group and remains the prevailing cause of infection-induced mortality worldwide, particularly in developing nations. We present a case of a 56-year-old woman with diabetes who was diagnosed with Pulmonary Tuberculosis. After receiving antituberculosis drugs as part of her treatment, she experienced a range of systemic manifestations and suffered from severe ulcerative esophagitis. This adverse reaction led to uncontrollable gastrointestinal intolerance, tragically resulting in her untimely demise. The incident underscores the potential seriousness of adverse reactions that can arise from tuberculosis treatment medications.

Abstract We describe the toxicity of multiwalled carbon nanotubes (MWCNTs) in two aquatic species: Danio rerio and Artemia salina. Fish were exposed to 25 mg L-1, 50 mg L-1, and 100 mg L-1 MWCNTs for 7 days. After exposure, the gills from D. rerio showed lamellar fusion and epithelial lifting in the secondary lamellae, and vasodilation in the primary lamellae. In the gills, heat shock protein 70 and Bax (pro apoptotic member) were stained more intensely in the treated groups than in the control group. The nauplii of A. salina were exposed to 25 µg L-1, 50 µg L-1, and 100 µg L-1 MWCNTs for 96 h. After exposure, the nauplii from the control group presented 20 % mortality, whereas the 25 µg mL-1, 50 µg mL-1, and 100 µg L-1 groups had 46.7 %, 70 %, and 100 % mortality, respectively. The nauplii exposed to 25 µg mL1 and 50 µg mL1 MWCNTs had black aggregates in the intestine because of the uptake of nanomaterials. In addition, the 25 µg mL-1 and 50 µg mL-1 MWCNT groups had black aggregates attached onto the body surface, appendages of the second pair, and mandibles.The results revealed the toxic effects of MWCNTs on the two aquatic organisms, and both species showed great potential for toxicological evaluation of MWCNTs in aquatic environments.
