Authors: Nazarchuk Oleksandr , Denysko Tetyana
Published: May 2024

The aim was to study the antimicrobial activity of new biomaterials based on decamethoxine and commercially available wound dressings against reference and clinical strains of S.aureus and E.coli.
Materials and methods. Developed biomaterials with 0.05 % decamethoxine (DCM No. 1-3) and wound dressings containing antiseptics Suprasorb®, SILVERCEL®, Urgotul SSD®, GUANPOLISEPT®, Bétadine® were used for the study. Antimicrobial properties were studied by zone of inhibition (ZOI) testing using the Kirby-Bauer method.
Results. In relation to S.aureus ATCC 25923, a significantly higher antimicrobial activity of biomaterials with DCM compared to silver- and iodine-containing wound dressings was found to be 1.97-2.11 (p <0.001) and 1.73-1.86 times (p <0.001), respectively. Similar activity against S.aureus ATCC 25923 was possessed by all three samples with DCM (ZOI - from 21.98±0.18 to 23.58±0.26 mm) and Suprasorb® (19.31±0.17 mm), Guanpolisept® (19.13±0.12 mm). Such a tendency was also found in relation to clinical strains of staphylococci. A high level of activity against E.coli ATCC 25922 was shown by biomaterials No. 1-3 DCM (ZOI - from 19.01±0.33 to 21.54±0.23 mm), Guanpolisept® (18.74±0.12 mm) and Suprasorb® (18.43±0.13 mm). Clinical strains of E.coli showed greater tolerance to antimicrobial biomaterials: the difference in mean values between the ZOI of the reference and ZOI of clinical strains of E.coli was significant for all biomaterials (p <0.001). The most effective were biomaterials with DCM No. 1-3 (ZOI - from 15.58±0.25 to 16.41±0.16 mm), as well as Suprasorb® (15.82±0.31 mm).
Conclusions. Biomaterials based on decamethoxine No. 1, No. 2, No. 3, Suprasorb®, Guanpolisept®, and Bétadine® have the highest antistaphylococcal activity. Biomaterials with decamethoxin No.1-3, Suprasorb® and Guanpolisept® show the strongest effect on reference and clinical strains of E.coli

Monitoring chlorophyll-a concentration (Chla) in inland waters is vital for environmental assessment. This study develops an empirical multivariate linear regression (MLR) model to directly estimate Chla in Quan Son Reservoir using Sentinel-2B (S2B) Level 2A images. Regression analysis of a 68-point in-situ Chla dataset measured in Quan Son Reservoir between 2021 and 2023, in conjunction with the corresponding S2B reflectance data, reveals a significant correlation between Chla and a combination of the blue (B2), green (B3), and red (B4) bands (coefficient of determination, R² = 0.95). The Chla estimation model is validated using a 30-point in-situ dataset collected on various dates (R² = 0.87; the root-mean-squared error RMSE < 5%). Subsequently, the model is applied to ten S2B images acquired from 2021 to 2023, revealing Chla's spatio-temporal distribution across the reservoir. Two key trends emerge: (1) Chla is lower during winter (November and December) than in summer and early autumn (July and September), and (2) The distribution of Chla undergoes noticeable spatial changes, particularly in July, with elevated levels observed in areas characterized by tourist hotspots. This approach shows promise for monitoring Chla in similar inland waters.
Estimation of greenhouse gas emission due to open burning of rice straw using Sentinel data
Authors: Nguyen Cong Giang , Nguyen Quyet Chien , Dang Vu Khac
Published: May 2024

In recent decades, Vietnam has gradually become a critical global rice producer. During that production process, residual straw becomes an environmental pollutant due to open burning, raising greenhouse gas emissions. This study combines the optical images of the Sentinel-2 satellite and the radar images of the Sentinel-1 satellite to estimate the dry biomass of rice and to determine gas emissions due to rice straw burning over the fields in Quoc Oai district, Hanoi city for urban environmental management purposes. Sentinel-2 images have been classified into the land covers, thereby identifying the areas of ​​rice cultivation and the areas of ​​burned straw. Meanwhile, the Sentinel-1 radar image has been used to calculate the dry biomass of rice due to its ability to penetrate clouds, an obstacle to optical images in tropical regions.
Furthermore, a field trip during harvesting season allows us to measure aboveground dry biomass. Then, the analysis shows a high correlation between the backscatter V.V. and V.H. of the radar image and the in-situ dry biomass (R=0.923 and R2=0.852), with a relatively low average error (RMSE = 6.58 kg/100 m2). By linear regression method, the study found the total rice dry biomass of 28728.5 tons, which was obtained after the Summer rice crop 2020 for the whole Quoc Oai district, of which 2037.91 tons of rice straw have been burned, releasing a large amount of greenhouse gas emission with 2398.6 tons of CO2, 189.5 tons of CO, 18.8673 tons of PM10 dust, 17.2087 tons of PM2.5 dust and some other gases. The identical procedure has also been applied to the western region of Hanoi city center to estimate the amount of gas emissions. This study has proven the effectiveness of an approach and contributed to supporting urban managers in proposing appropriate policies to monitor and protect the environment.

Abstract Objective: To evaluate the indications for and results of magnetic resonance imaging (MRI) examinations for breast cancer screening at a cancer center in Brazil. Materials and Methods: This was a retrospective observational study, based on electronic medical records, of patients undergoing MRI for breast cancer screening at a cancer center in Brazil. Results: We included 597 patients between 19 and 82 years of age. The main indications for MRI screening were a personal history of breast cancer, in 354 patients (59.3%), a family history of breast cancer, in 102 (17.1%), and a confirmed genetic mutation, in 67 (11.2%). The MRI result was classified, in accordance with the categories defined in the Breast Imaging Reporting and Data System, as benign (category 1 or 2), in 425 patients (71.2%), probably benign (category 3), in 143 (24.0%), or suspicious (category 4 or 5), in 29 (4.9%). On MRI, 11 malignant tumors were identified, all of which were invasive carcinomas. Among those 11 carcinomas, six (54.5%) were categorized as minimal cancers (< 1 cm), and the axillary lymph nodes were negative in 10 (90.9%). The cancer detection rate was 18.4/1,000 examinations, and the positive predictive value for suspicious lesions submitted to biopsy was 37.9%. Conclusion: In our sample, the main indication for breast MRI screening was a personal history of breast cancer. The results indicate that MRI is a highly accurate method for the early detection of breast neoplasms in this population.

Published: May 2024

RESUMO O objetivo deste trabalho foi avaliar a tixoconformabilidade da liga Al4Si2.5Cu sob duas diferentes rotas de produção: técnica via refino de grão e via agitação eletromagnética, abrangendo desde a obtenção da liga até sua caracterização microestrutural e mecânica após o processo de tixoforjamento em uma prensa excêntrica mecânica. A liga foi submetida a tratamentos térmicos de globularização que promovem a globularização das partículas de fase primária pelos tempos de 0s e 210s na fração sólida de 45% e na sequencia tixoforjada. Os ensaios de tixoforjamento mostraram que a força necessária de fechamento da matriz é praticamente constante, independentemente do tempo de globularização, ficando em torno de 70 kN, utilizando menos de um terço da capacidade da prensa. Com relação a sua morfologia para ambas as rotas de produção, a mesma apresentou morfologia globular para ambos os tempos de tratamento térmico. As peças tixoforjadas apresentaram boa conformabilidade preenchendo toda a matriz e reproduzindo sua geometria, além de apresentar boas propriedades mecânicas nos ensaios de tração, ou seja, o valor limite de resistência à tração principalmente quando utilizado a rota de produção via agitação eletromagnética apresentou valores próximos a 200 MPa. Demonstrando que a liga torna-se propicia aos processos de tixoconformação.

Abstract This study presents a survey of small-stream fish species from the Purus-Madeira interfluve, collected in four streams near Humaitá on the highway BR-319. The results reveal a rich and diversified ichthyofauna with 3016 collected individuals distributed in 84 species, six orders, 25 families, and 60 genera. Of all the specimens collected, the Characiformes was the most representative, with eight families, 26 genera, and 42 species, followed Siluriformes, with nine families, 20 genera, and 23 species. In terms of families, Characidae had the highest number of species (25), followed by Loricariidae (9), and Cichlidae (8). Among the 95 captured species,s 11 are the first records for the region, evidencing a high diversity in these environments. Of the 84 species recorded in this study, 15 have not been assessed by the IUCN, while the remaining 62 include 23 listed as Least Concern (LC), three as data deficient (DD), and one as Near Threatened (NT). The southeastern Amazon region still has few fish surveys, especially in the region comprising the Purus-Madeira Interfluve, which highlights the importance of surveys to fill gaps and understand the biodiversity distribution patterns in the region.

Abstract Studies of marine and estuarine red algae (Rhodophyta) are in the early stages in the littoral of the Sian Ka’an Biosphere Reserve, Mexico. The inventory of these organisms was made based on samples obtained from ten sampling during 2009 to 2015 in 22 localities, eight of them in marine and fourteen in estuarine environments. We found 182 species and subspecific taxa of Rhodophyta. The Rhodomelaceae family was the best represented with 65 taxa, followed by Ceramiaceae 13 and Delesseriaceae 12. Of the 182 taxa, 25 are new records Sian Ka’an Biosphere Reserve with Harveylithon rupestre, Spongites fruticulosus, Acrochaetium barbadense, Dasya harveyi, Chondria pumila, Spermothamnion repens, Metapeyssonnelia milleporoides and M. tangerina being new records for the Mexican Caribbean. Of the 182 species, 119 of them are epiphytes, most of them, 54, grew exclusively on other macroalgae, 29 on mangrove roots and 8 on Thalassia leaves. The floristic list is accompanied by data on seasonality, reproduction, habitat, and environment. Species diversity was compared between the winter rains, dry and rainy seasons during the period study. The Rhodophyta of the Sian Ka’an Biosphere Reserve is tropical, and the greatest diversity was found in the marine environment with 83 taxa and during the winter rains with 132.

Published: May 2024

ABSTRACT The occurrence of Toxoplasma gondii, Neospora caninum, Ehrlichia canis and Babesia vogeli in dogs from the municipality of Cândido Sales, Bahia, was investigated. Total and peripheral blood samples were obtained from 131 dogs. Blood smears were performed to check for morulae. Toxoplasma gondii and N. caninum infections were determined by an Indirect Immunofluorescence Reaction. Nested-PCR and PCR were used for the diagnoses of E. canis and B. vogeli infections, respectively. Additionally, the risk factors associated with infection by these agents were analyzed. The frequency of infection was 70.2% for N. caninum, 67.9% for T. gondii and 37.4% for E. canis. None of the dogs tested positive for B. vogeli. Morulae of Ehrlichia spp. were identified in two animals and the piroplasm in one animal. Age (> 3 years) was considered a risk factor for infections by E. canis and N. caninum and the rural habitat for infections by N. caninum. Co-infections were frequent, mainly with N. caninum and T. gondii (45.03% of dogs). Ehrlichia canis infection was significantly associated with N. caninum and T. gondii infection. These findings indicated a high occurrence of T. gondii, N. caninum, and E. canis in the studied region.

Published: May 2024

ABSTRACT This study aimed to evaluate whether the use of trometamol ketorolac for 30 consecutive days may change the blood count, the serum biochemistry profile, and the urinalysis of healthy dogs. Eleven small breed dogs (4.6-10kg), with ages ranging from 1 to 9 years were enrolled in the study. Dogs received 40μL of 0.4% trometamol ketorolac eye drops, every 12 h in both eyes for 30 consecutive days. Blood and urine samples were collected at baseline, and following 15 and 30 days of the beginning of the treatment. Creatinine levels increased significantly at day 15 (1.21±0.1mg/dL) and 30 (1.22±0.1mg/dL) when compared with baseline (0.94±0.1mg/dL) (P<0.01). Significantly increased values of serum potassium were observed only at day 30 (4.66±0.15mEq/L), when compared with day 15 (4.32±0.12mEq/L) and baseline (4.36±0.15mEq/L) (P<0.05). The other hematological and biochemical parameters did not change significantly during the study (P>0.05). From observations of our study, it can be concluded that the instillation of trometamol ketorolac for 30 consecutive days did not cause clinically relevant changes in the blood count, biochemistry profile and in the urinalysis of healthy dogs.

Published: May 2024

ABSTRACT A case of peripheral primitive neuroectodermal tumor in the cervical region of a canine is described. The patient was a canine, male, five years old, large size, with acute neurological clinical signs, severe neck pain and tetraplegia. On computed tomography, an oval-shaped mass located dorsally to cervical vertebrae C4 to C7 was observed, with infiltration over the spinal cord between vertebrae C4 and C5, discreetly widening the dorsal intervertebral foramina of the cervical vertebrae and compressing the dorsal portion of the spinal cord of this segment. Under microscopy, the neoplastic cells were small, irregular in shape and with scarce cytoplasm. Immunoreactivity for vimentin, which can only be expressed in PTNEs tumors, was decisive for diagnostic confirmation. Additionally, the positivity of the S-100 protein, which is expressed in neuroectodermal cells mainly of the neural crest cells, reinforced the classification as PTNE, and the negativity in the expression for glial fibrillary acidic protein (GFAP) ruled out the presence of small cell glioma of the central nervous system. Based on the clinical history, imaging exams, cellular morphology and mainly on immunohistochemical staining, the diagnosis of primitive neuroectodermal tumor (PTNE) with infiltration and compression of the spinal cord in the cervical region of the dog was confirmed, considered uncommon in this species.

ABSTRACT This study aimed to determine the effectiveness of topical HoofCare® in the treatment of digital dermatitis (DD) in dairy cows. Thirty-six high-yielding Holstein cows with DD in at least one limb were included and randomly divided into two groups, making 42 limbs. The alternating treatment group consisted of 21 limbs treated for three alternating days every 48h, and the continuous treatment group consisted of 21 limbs treated every 24h for five days. The cows underwent lameness examination, thermographic analysis, and qualitative and quantitative analysis of the lesions on D0 (time of identification of the lesion and prior to treatment), D4 (fourth day of treatment), and D10 (five days after the end of treatment). The data were compared between different time points and groups. There was no significant difference between the groups for the variables evaluated. However, both groups presented a reduction in the degree of lameness around the lesion, in the local temperature, and regression from the active to the inactive stage of the lesions. Thus, this short-term study demonstrates the suggestive efficacy of HoofCare® in treating DD and recommends conducting further long-term studies.

ABSTRACT Despite the significance of adipose-derived stem cells in complementary and regenerative medicine, studies regarding clinical safety for allogeneic intravenous administration in healthy dogs remain insufficiently conducted. This study aimed to assess cellular viability through laboratory and microbiological evidence, along with genetic markers, in addition to evaluating clinic-laboratory safety for allogeneic intravenous administration of adipose-derived stem cells in healthy dogs. To achieve this, two cell batches and eight dogs were included in the study. The results revealed positive genetic markers for CD29, CD44, CD105, SOX2, and OCT3.4. Both batches exhibited positive cell differentiation into adipocytes, chondrocytes, and osteoblasts. Microbiological evidence showed negative results, and cell viability after thawing indicated 92% and 88.5% viable cells after 30 minutes, and 86% and 83.5% after 24 hours, respectively, for both batches. Hematological cell counts and serum biochemical enzyme levels, before and after intravenous treatment, did not exhibit statistical differences between the time points (p>0.05). Median values remained within the reference range for the species during and after 30 days of treatment. Based on the cellular viability results, observed patterns, and the absence of hematological side effects, it can be concluded that intravenous therapy with allogeneic adipose-derived stem cells is clinically safe.

ABSTRACT Sixty adrenals of 30 dogs were evaluated, divided into three groups, according to age: Group 1 = healthy youngsters (10 animals) - from one to three years old; Group 2 = healthy adults (10 animals) - four to nine years old; and Group 3 = healthy senile animals (10 animals) - older than ten years old. The experimental design was randomized, with a significance of 5%. There was a significant difference (P=0.017) in length between young and elderly dogs. The thickness of the cranial pole showed a significant difference (P=0.001) between young and adults when compared with the elderly group. The thickness of the caudal pole was not significant for adults when compared to elderly and young people. Between elderly and young, the difference was significant (P=0.024). The mean speeds differed between the groups of young and adult animals regarding the left adrenal and its cranial pole. The hardness pattern and its measurements can vary in healthy dogs of different ages, being more rigid in the cranial pole of the left adrenal in young dogs.

ABSTRACT This study aimed to evaluate the effect of different levels of omega-3 polyunsaturated fatty acids (n-3 PUFA) in the diet of Sardinella brasiliensis on their hematological parameters. A total of 375 fish were distributed in 15 experimental units to evaluate the effects of the diet on their blood for 45 days. The levels of n-3 PUFA added in the diet were 0, 0.3, 0.6, 0.9, and 1.2% of the lipid fraction. These values represent the total percentage of n-3 PUFA in the lipid fraction of the diet, and 0% n-3 PUFA was used as the negative control. Five fish from each experimental unit were sampled at the end of the experiment for hematological analysis, and the parameters measured include the total number of erythrocytes, hematocrit percentage, hemoglobin and glucose concentration and differential leukocyte count. Higher numbers of circulating eosinophils were observed in fish fed 0.3% and 1.2% n-3 PUFA. Although no significant differences were observed in several of the parameters, the results demonstrate that the health of the sardines was not affected by the addition of n-3 PUFA in their diet. It should be emphasized that this is the first study with emphasis on the blood analysis of S. brasiliensis.

ABSTRACT This research aimed to carry out an epidemiological investigation of dogs with canine leishmaniasis in an area of Rio Grande do Sul with no history of notification of the disease. Leishmaniasis is considered an endemic zoonosis in different countries. In Brazil, it occurs mainly in the Southeast and Midwest regions, having drastically increased the number of notifications in recent years. In the state of Rio Grande do Sul, there are reports of the disease in the metropolitan region of Porto Alegre and in the border region in the west of the state, as well as in the central region. The investigation was conducted in 100 dogs from the municipalities of Frederico Westphalen and region. Whole blood was collected for immunochromatographic testing (TR DPP® Canine Visceral Leishmaniasis) and lymph node aspiration. Positives were confirmed by ELISA test and indirect immunofluorescence test with total dilution or immunohistochemistry after skin biopsy. Two animals were diagnosed with visceral leishmaniasis, considered the first reported cases of the disease in the canine population in the region. Therefore, it becomes necessary to research and control the potential presence of sandflies in the area. There is a hypothesis that the animals were contaminated in other regions of the country, remaining as a reservoir until the moment of diagnosis.

ABSTRACT Objective Evaluate the food consumption of the participants of the Cohort of Universities of Minas Gerais, according to the degree of processing, and its relationship with socioeconomic, behavioral, and individual factors. Methods A total of 4,124 individuals from the baseline of the Cohort of Universities of Minas Gerais (2016 and 2018) participated in this study. Food consumption was self-reported by completing an online Food Frequency Questionnaire. The foods were divided into 3 groups: Group 1, in natura, minimally processed foods, culinary ingredients and culinary preparations; Group 2, processed foods; Group 3, ultra-processed foods. A hierarchical multiple linear regression model was used to verify the associated factors. Results Regarding the factors associated with food consumption, it is noteworthy that Group 1 was positively associated with the practice of physical activity, female gender, age, “non-white” skin color, and the presence of diabetes Mellitus; and negatively with “not married/without stable union” marital status, alcohol abuse, tobacco use, obesity, and depression. Considering Group 2, it was positively associated with alcohol abuse, tobacco use, and age; and negatively with physical activity, female gender, and “non-white” skin color. As for Group 3 it was positively associated with a marital status of “not married/without stable union”, obesity, and depression; and negatively with physical activity, age, “non-white" skin color, and presence of diabetes Mellitus. Conclusion The factors that are in at least one of the final hierarchical linear regression models stand out: marital status, physical activity, alcohol abuse, tobacco use, sex, age, skin color, obesity, diabetes mellitus, and depression.

ABSTRACT Objective: to identify sociodemographic factors, clinical conditions and sarcopenia parameters that predict hospital admission and death in older adults with cognitive impairment. Method: this is a longitudinal observational study carried out with 170 older adults with cognitive impairment assessed between 2019 and 2021. Predictor variables were sociodemographic characteristics, clinical conditions and sarcopenia parameters. Sarcopenia was operationalized through handgrip muscle strength (dynamometry), muscle mass (calf circumference) and the Timed Up and Go test. Occurrence of hospital admission and death within one year after assessment of older adults were the predicted variables. Analyzes were carried out using descriptive statistics, independent Student’ t-test, Mann-Whitney U test, chi-square test and univariate logistic regression. Results: most participants were female (±77.57 years old), with low education, sedentary, 15.9% with sarcopenia and 13% with a history of hospital admission. It was identified that education level had an effect on occurrence of hospital admission (U=1,423.5, p=0.027) and death (U=647.0, p=0.025) within one-year follow-up. Furthermore, there is an association between history of hospital admission in the last 6 months and occurrence of hospital admission [χ2(1)=4.729; p=0.030] and death [χ2(1)=3.919; p=0.048] within one year follow-up. It was identified that history of hospital admission in the last 6 months was associated with occurrence of hospital admission within one-year follow-up (OR=2.963; 95%CI 1.076-8.165, p=0.036). Conclusion: history of hospital admission in the last six months is associated with occurrence of hospital admission over a year in older adults with cognitive impairment.

RESUMO: No início do século XX, intensificaram-se as pesquisas relacionadas ao desenvolvimento infantil. Helena Antipoff (1892-1974) foi uma pesquisadora e professora que dedicou seus estudos a esse tema, principalmente no que se refere ao desenvolvimento das crianças nomeadas na época como “anormais”. Um dos instrumentos elaborados por ela foi a Ficha de Observação do Desenvolvimento Mental da Criança, em 1939. A Classificação Internacional de Funcionalidade, Incapacidade e Saúde (CIF), proposta pela Organização Mundial de Saúde (OMS), sugere uma avaliação da condição do sujeito baseada nos aspectos biológicos, psíquicos e sociais, em contraposição a uma avaliação baseada somente no critério da doença ou da incapacidade. Assim sendo, o objetivo deste estudo foi resgatar a Ficha de Observação proposta por Helena Antipoff e compará-la à CIF, utilizando os guias recomendados por Alarcos Cieza e colaboradores. Os resultados apontam que a maioria dos itens da ficha puderam ser codificados e relacionados à CIF, pois os itens da ficha de Antipoff buscam também avaliar, de forma associada, funções do corpo, atividade e participação, podendo ser utilizados como instrumento de avaliação prévia da criança, devendo, ainda, serem atualizados com uma nomenclatura mais atual, baseada na nomenclatura empregada na CIF.

ABSTRACT Objective: To detect spatial and spatiotemporal clusters of urban arboviruses and to investigate whether the social development index (SDI) and irregular waste disposal are related to the coefficient of urban arboviruses detection in São Luís, state of Maranhão, Brazil. Methods: The confirmed cases of Dengue, Zika and Chikungunya in São Luís, from 2015 to 2019, were georeferenced to the census tract of residence. The Bayesian Conditional Autoregressive regression model was used to identify the association between SDI and irregular waste disposal sites and the coefficient of urban arboviruses detection. Results: The spatial pattern of arboviruses pointed to the predominance of a low-incidence cluster, except 2016. For the years 2015, 2016, 2017, and 2019, an increase of one unit of waste disposal site increased the coefficient of arboviruses detection in 1.25, 1.09, 1.23, and 1.13 cases of arboviruses per 100 thousand inhabitants, respectively. The SDI was not associated with the coefficient of arboviruses detection. Conclusion: In São Luís, spatiotemporal risk clusters for the occurrence of arboviruses and a positive association between the coefficient of arbovirus detection and sites of irregular waste disposal were identified.

Published: May 2024

Abstract With the publication of Resolution CNE/CES nº 7 of 2018, which deals with the curricularization of extension, Higher Education Institutions (HEIs) were mobilized to comply with the guidelines established in that document. Given this scenario, this article aims to present some possibilities of indicators that can be used as a reference by professors of Administration and Accounting courses at HEIs in their extension actions. In addition to the implementation of the extension curricularization, it is also reflected on the evaluation of such actions. In methodological terms, a qualitative approach was taken, in a documentary research, based on the following documents: Resolution CNE/CES nº 7 of 2018, National Extension Policy of the Forum of Pro-Rectors for Extension of Public Institutions of Higher Education in Brasil and the announcement of the Federal University of ABC (UFABC). The results described dialogue with the current literature on the subject and advance towards a better understanding of the extension evaluation processes, especially for professors and coordinators of Administration and Accounting courses, in order to enable the systematization of extension actions, as well as allow the student to be the protagonist in the extension activities.

ABSTRACT Introduction: Acute kidney injury (AKI) is an abrupt deterioration of kidney function. The incidence of pediatric AKI is increasing worldwide, both in critically and non-critically ill settings. We aimed to characterize the presentation, etiology, evolution, and outcome of AKI in pediatric patients admitted to a tertiary care center. Methods: We performed a retrospective observational single-center study of patients aged 29 days to 17 years and 365 days admitted to our Pediatric Nephrology Unit from January 2012 to December 2021, with the diagnosis of AKI. AKI severity was categorized according to Kidney Disease Improving Global Outcomes (KDIGO) criteria. The outcomes considered were death or sequelae (proteinuria, hypertension, or changes in renal function at 3 to 6 months follow-up assessments). Results: Forty-six patients with a median age of 13.0 (3.5–15.5) years were included. About half of the patients (n = 24, 52.2%) had an identifiable risk factor for the development of AKI. Thirteen patients (28.3%) were anuric, and all of those were categorized as AKI KDIGO stage 3 (p < 0.001). Almost one quarter (n = 10, 21.7%) of patients required renal replacement therapy. Approximately 60% of patients (n = 26) had at least one sequelae, with proteinuria being the most common (n = 15, 38.5%; median (P25–75) urinary protein-to-creatinine ratio 0.30 (0.27–0.44) mg/mg), followed by reduced glomerular filtration rate (GFR) (n = 11, 27.5%; median (P25–75) GFR 75 (62–83) mL/min/1.73 m2). Conclusions: Pediatric AKI is associated with substantial morbidity, with potential for proteinuria development and renal function impairment and a relevant impact on long-term prognosis.

Published: May 2024

RESUMEN El presente artículo analiza las percepciones que docentes, directivos y asistentes de la educación tienen sobre las dimensiones que se consideran para conformar una Comunidad Profesional de Aprendizaje con el fin de identificar diferencias entre distintos contextos educativos. La metodología de investigación corresponde a un estudio mixto concurrente con estrategia de estudio de casos múltiples en tres centros educativos chilenos. Al considerar los resultados obtenidos del cuestionario PLCA-R, junto con los grupos de discusión, se observa que las percepciones de los tres casos coinciden al evaluar positivamente aquellas dimensiones vinculadas al desarrollo de la misión y los valores compartidos, así como las relaciones al interior de las comunidades y el aprendizaje colaborativo. Sin embargo, la práctica personal compartida y las condiciones y recursos para el desarrollo de Comunidad Profesional de Aprendizaje, aún son un desafío para equipos directivos y sostenedores.

For an integrative and pluralist ethics: pathways to moral education based on conflict resolution
Authors: Arantes Valéria Amorim , Pinheiro Viviane Potenza Guimarães
Published: May 2024

ABSTRACT This article aims to explore theoretical-methodological implications of the ethics of care for psychology and moral education. Taking the premise of multiple moral voices in connection, installed by Gilligan, the article analyzes interpersonal conflicts, through the Theory of Organizing Models of Thinking. From a research clipping with teenagers aged 14 to 16, in which interviews about interpersonal conflicts were applied, we present the analysis of two conflicts narrated by a young participant. We seek to highlight different phenomena of the human psyche in conflict resolution. The results showed the continuum between the desires of justice, care, happiness, and well-being in the elaboration of interpersonal relationships in different interactive contexts, giving visibility to relational ethics. Based on the results, we discuss some implications for educational practices aimed at ethical education aligned with acting for the personal and collective good.
Literacy practices and shared repertoire by teachers who teach mathematics
Authors: Silva Neomar Lacerda da , Oliveira Andréia Maria Pereira de
Published: May 2024

ABSTRACT This article aimed to identify and describe engagement in teaching literacy practices in which teachers who teach mathematics participated. We used a qualitative approach and analytical tools from the Social Theory of Learning and literacy as a social practice to identify and describe interactions with the uses of reading and writing in study meetings and lesson planning held in a public school. The empirical material was produced through observations, interviews, and documents. The results suggest that members engaged in literacy events mediated both by prescriptive texts and by texts produced by the group itself to organize the repertoire. However, the constitution of the shared repertoire occurred through engagement in literacy practices recognized and valued in the group. Although prescriptive texts guide the practices, the repertoire was not limited to these prescriptions, passing through the various social engagements of those involved.
Educação política, violência, resistência: a formação da consciência e o enfrentamento ao autoritarismo e à agressividade
Authors: Giovinazzo Júnior Carlos Antônio
Published: May 2024

RESUMO Ensaio no qual se apresenta reflexões sobre violência social e suas manifestações na escola. Trata-se de relação que jamais pode ser negligenciada, pois a educação também contém as tendências sociais que reproduzem a violência, a agressividade e a barbárie. Com base em autores da Escola de Frankfurt, discorre-se sobre o tema da violência, destacando seus nexos com o sistema social e econômico, que se reproduz exatamente promovendo a destruição de pessoas, culturas e o meio ambiente. Seguem considerações que evidenciam que tal destrutividade repercute na formação das subjetividades e das disposições de os indivíduos se conformarem ou resistirem a essa tendência. Por fim, aventa-se a possibilidade histórica de concretização da dimensão política da educação como forma de contraposição e enfrentamento da agressividade e violência inerentes às sociedades do capitalismo avançado.
