When determining the location of the fire source and establishing local temperatures in the fire zone inside the building, window panes are often objects of expert research. By their nature, glasses have various physicochemical properties (optical characteristics, hardness, etc.), various internal (structure, defects, inclusions) and external (surface quality, presence of coatings) structures. Under fire conditions, under thermal and mechanical action, these properties may vary. The results of studying the microrelief of the glass surface subjected to heat treatment at different temperatures and heating times by atomic force microscopy are presented. Histograms of values of image elements (elevations of relief) were constructed based on results of scanning of samples relief and values of arithmetic mean and square mean roughness of glass surface before and after heat treatment were calculated. It has been found that the roughness of the glass surface decreases during the heat treatment process. The further development of studies by atomic force microscopy of window glass fragments that have been in the fire zone may make it possible to establish the temperature to which the glass fragments were subjected. The location of such fragments in the completed fire zone may indicate the direction to the location of the hottest combustion zone in accordance with a decrease in the roughness values of the window glass fragments that have been in the combustion zone.

Abstract Objective: To evaluate the results obtained with an artificial intelligence-based software for predicting the risk of malignancy in breast masses from ultrasound images. Materials and Methods: This was a retrospective, single-center study evaluating 555 breast masses submitted to percutaneous biopsy at a cancer referral center. Ultrasonographic findings were classified in accordance with the BI-RADS lexicon. The images were analyzed by using Koios DS Breast software and classified as benign, probably benign, low to intermediate suspicion, high suspicion, or probably malignant. The histological classification was considered the reference standard. Results: The mean age of the patients was 51 years, and the mean mass size was 16 mm. The radiologist evaluation had a sensitivity and specificity of 99.1% and 34.0%, respectively, compared with 98.2% and 39.0%, respectively, for the software evaluation. The positive predictive value for malignancy for the BI-RADS categories was similar between the radiologist and software evaluations. Two false-negative results were identified in the radiologist evaluation, the masses in question being classified as suspicious by the software, whereas four false-negative results were identified in the software evaluation, the masses in question being classified as suspicious by the radiologist. Conclusion: In our sample, the performance of artificial intelligence-based software was comparable to that of a radiologist.

Published: December 2023

Abstract Objective: To evaluate the preoperative muscle mass of patients with head and neck cancer (HNC) with computed tomography (CT), comparing the results obtained through analysis of cross-sectional areas at the level of the third lumbar vertebra (L3) with those obtained through analysis of cross-sectional areas at the levels of the third cervical and fourth thoracic vertebrae (C3 and T4, respectively). Materials and Methods: A total of 63 patients with HNC were evaluated preoperatively. Using CT, we assessed muscle mass at L3, as well as at C3 and T4. Results: Most (73.0%) of the patients had low muscle mass at L3, whereas 50.8% had a normal body mass index. The cross-sectional area at L3 correlated strongly with those at C3 and T4 (r = 0.831 and r = 0.763, respectively; p < 0.001 for both). In addition, the muscle mass index at L3 correlated strongly with those at C3 and T4 (r = 0.781 and r = 0.715, respectively; p < 0.001 for both). Conclusion: Low muscle mass appears to be highly prevalent in patients with HNC. Measurements at C3 and T4 could represent alternative means of assessing muscle mass in such patients.

Published: December 2023

ABSTRACT Actinidia Lindl., commonly known as kiwifruit, is a valuable berry crop. The area of commercial kiwifruit plantations is increasing; the global production of kiwifruit is about 0.62% of the total production of major fruit crops. The use of biotechnological methods, which can significantly accelerate the propagation of quality planting materials, is considered to be relevant for the propagation of this crop. In this study, we optimized the culture medium composition at the micropropagation stage for the effective cultivation of promising cultivars of A. arguta, A. kolomikta, and A. polygama. We investigated the features of Actinidia morphogenesis depending on the genotype, the concentration of 6-Benzylaminopurine (0.5, 0.8, and 1.0 mg L-1), and plant growth regulators (6-Benzylaminopurine, meta-topolin, and 2-isopentenyladenine at a concentration of 0.5 mg L-1) in the media Quoirin and Lepoivre. Actinidia arguta (multiplication rate of 8.0) and A. polygama (6.8) developed faster at the micropropagation stage compared to A. kolomikta (4.9). The studied Actinidia representatives were cultured most effectively on Quoirin and Lepoivre media supplemented with 0.5 mg L-1 meta-topolin, compared to the media containing 0.5 mg L-1 6-Benzylaminopurine and 0.5 mg L-1 2-isopentenyladenine. The use of meta-topolin in the medium contributed to the increase in various morphometric traits, such as the height of microshoots (up to 28% depending on the species), their number (up to 52%), and their multiplication rate (up to 42%). We also recorded a high morphogenic capacity of the investigated species.

Authors: Bortoli Maritsa Carla , Sanine Patricia Rodrigues , Araújo Bruna Carolina de , Oliveira Cintia de Freitas , Costa Maria Izabel Sanches , Tesser Taís Rodrigues
Published: December 2023

Abstract Primary Health Care is the gateway for users to access the Brazilian healthcare system and has been particularly affected by the COVID-19 pandemic demands. This review systematically identified and mapped evidence regarding novel or adapted strategies developed within PHC during the COVID-19 pandemic in Brazil. Our results are presented as a narrative synthesis following the JBI methodology. They were analyzed and discussed through the lens of the Health Work Process Theory, which allowed us to categorize the publications into two principal domains of strategies, managerial and clinical, encompassing strategies that were new, adapted, or maintained in healthcare services. Two hundred twenty-six interventions were identified (130 managerial and 96 clinical) from 49 studies. The new strategies appeared more frequently in both domains, while the maintained ones were less prevalent. The array of interventions highlights different care models, sometimes aligned with a biomedical approach. In contrast, others focus on comprehensiveness and longitudinality based on a person-centered care, in the family, and the community. Thus, this review identified that the same pre-pandemic challenges persist.

Published: December 2023

Resumo O objetivo do estudo foi identificar a percepção dos gestores municipais sobre os recursos extraordinários e seus usos no enfrentamento à COVID-19. Trata-se de estudo de casos múltiplos, de métodos mistos incorporados. Foram realizadas entrevistas semiestruturadas com seis municípios-caso do estado de São Paulo. Foram analisados dados secundários extraídos de sistemas de informação no período de 2020 a 2022. As distintas realidades municipais em termos populacionais, de gastos em saúde e de acesso aos recursos federais permitiram observar diferentes estratégias de gestão financeira e alocação dos recursos. Além dos recursos extraordinários, foi possível identificar, no período analisado, a presença relevante de repasses por Emendas Parlamentares. No contexto de desfinanciamento do SUS, esses recursos e repasses significaram, em muitos casos, a possibilidade de os gestores organizarem o sistema de saúde municipal segundo seu entendimento das necessidades de saúde e as respostas possíveis a essas necessidades. Evidenciou-se que os recursos para o enfrentamento à COVID-19 foram alocados principalmente na média e alta complexidade e na contratação de empresas privadas.

Published: December 2023

Resumo O artigo tem como objetivo compreender como os municípios paulistas organizaram o enfrentamento da pandemia de COVID-19, destacando o papel da Atenção Primária à Saúde (APS) como elemento analisador do modelo de atenção. Estudo quantitativo descritivo a partir da realização de inquérito com uma amostra probabilística de 253 municípios do estado de São Paulo no qual foram entrevistados gestores municipais por meio de questionário. A descrição das frequências absolutas (n) e relativas (%) foi feita após ponderação segundo os três estratos de portes populacionais. Os resultados indicam que o elemento de porte populacional constitui importante componente analítico. A organização durante a pandemia priorizou, na maioria dos municípios, reajuste de fluxo e cuidados clínicos. As ações continuadas de pré-natal e puericultura também eram de caráter biomédico, com consultas. Em relação ao fomento de respostas de cuidado ampliado e territorial, os municípios de menor porte, com centralidade na APS, tiveram um desempenho superior. Já os municípios de grande porte fragmentaram o cuidado e a vacinação. As ações intersetoriais, de cuidado comunitário, e de utilização da perspectiva territorial, mostraram-se ainda retraídas e persistem dificuldades da APS.
The role of PHC in times of crisis: an analysis of discretion of health workers during the COVID-19 pandemic
Authors: Fernandez Michelle , Magri Giordano , Maia Barbara , Lotta Gabriela
Published: December 2023

Abstract Crises are exceptional events that alter the structural arrangements under which street-level bureaucrats (SLBs) normally operate, generating resource shortages, the suspension of rules and routines, and changes in work practices. These characteristics highlight the importance of room for discretion, since quick decisions need to be made in a context pervaded by unpredictability. This study analyzed the impact of the COVID-19 pandemic in Brazil on the discretion of primary health care workers, seeking to understand which factors influence the exercise of discretion, focusing on organizational, emotional and scientific aspects. We used data from an online survey comprising open- and closed-ended questions conducted in March 2021 with 1218 primary care workers. The results show that, unexpectedly, discretion of SLBs does not become a panacea for the crisis. A large portion of professionals continued to operate within the rules, demonstrating a tendency to seek support at work, either through better organizational conditions, the reduction of uncertainty or from science.

Published: December 2023

Abstract This article aims to estimate the excess of deaths in the years 2020 and 2021 in Mato Grosso state, in the state capital and in the countryside, according to gender and age group. Data was extracted from DATASUS/Ministry of Health website for the period from 2015 to 2020 and from the website of the State Department of Health - Data Warehouse System (DW) for 2021. Non-fetal deaths by natural causes of residents in Mato Grosso were analyzed and the analyses were broken down into countryside and state capital (Cuiabá). The variables selected were age group, gender, month of occurrence, and underlying cause of death. Excess mortality was calculated using generalized additive quasi-Poisson model adjustments with correction for overdispersion. A 30% excess of deaths was identified in 2020, with the state capital recording the highest estimate, in older age groups, and between the months of July and September. In 2021, the expected number of deaths was 57% higher, with the double in the younger age groups in the countryside. The study showed different demographic profiles of excess deaths in the years 2020 and 2021 during COVID-19 pandemic and distinct patterns between countryside and state capital, suggesting inequalities that may have caused impact on different risks.

ABSTRACT Objective: To analyze the trend in the detection rate of Syphilis in Pregnant Women (SP) and in the incidence rate of Congenital Syphilis (CS) in the state of Ceará. Methods: This is an ecological study that used the technique of interrupted time series to analyze monthly data on cases of SP and CS obtained from the Department of Informatics of the Brazilian Unified Health System (DATASUS) from January 2015 to July 2021. The Kernel test and the Lincoln-Petersen estimate were used to analyze the statistical significance. Results: In 2015, a monthly detection rate of SP was estimated at 5.4 and a CS incidence rate of 8.2 per one thousand live births (LB). The implementation of the ordinance that changed the criteria for defining cases of SP and CS resulted in an increase of 4.9 (p<0.0001; 95%CI; 3.33; 6.61) in the detection rate of SP and a decrease of 0.1 on the incidence of CS (p<0.001; 95%CI -0.2; -0.1). The COVID-19 pandemic did not impact the monthly detection rate of SP (p=0.558; 95%CI 5.92; 3.22), nor its trend (p=0.7397; 95%CI 0.28; 0.3), but there was an increase of 0.19 in CS (p<0.001; 95%CI 0.1; -0.31). Conclusion: Between 2015 and June 2021, the trend in the detection rate of SP and in the incidence rate of CS was impacted by changes in the criteria for defining cases of these diseases proposed by the Brazilian Ministry of Health and the COVID-19 pandemic.

Abstract Introduction: Assessment is paramount in the resident physician’s teaching-learning process. The Mini-CEX is considered an appropriate instrument to carry out formative assessment, allowing structured educational feedback. In this context, residency preceptors need to undergo a continuous training process to better prepare their residents, and a viable form of training is using Distance Education (EaD). Objective: To develop and validate a Distance Education (EaD) course on Mini-CEX for residency preceptors in Mastology. Method: Development and validation of a technical-educational product, in the format of a training course and in the Distance Education modality (EaD). The consensus group technique was used in the product content validation process. Semantic validation was carried out through a validation questionnaire applied to the preceptors involved in the residency program in Mastology. Results: A self-instructional and unmediated course was designed and validated, with a total workload of 02 (two) hours. The course was approved by the target audience, as it had an overall average score of 98% satisfaction and a Cronbach’s alpha equal to 0.8. Conclusions: The course developed and validated on Mini-CEX presents itself as a relevant option for the training of medical residency preceptors in Mastology and can be extended to any medical residency service. It should be noted that the Distance Education (EaD) course favors the adherence of the target audience, with an accessible format to strengthen knowledge on the subject, in addition to encouraging preceptors to also use the educational evaluation.

Published: December 2023

Abstract Tracheary elements can be classified as tracheids or vessel elements. In ferns, both cell types and even cells with intermediate characteristics can be observed. For a long time, the methods employed in the study of these cells were questioned and consequently their classification as well. In the present work, we analyze the stem tracheal elements of 13 Aspleniaceae species, occurring in different habitats and belonging to different clades. The samples were cut, dried on a hotplate, metallized, and analyzed in SEM. In general, the Asplenium species analyzed contain elongated conducting cells with oblique end walls, with scalariform thickening on all faces of the cell. The presence of pit membranes, however, varies greatly among species, it being possible to observe species with tracheids, with intermittent perforation plates, and with vessel elements.
In vitro spore germination and gametophyte development of two Cyathea species of South America in response to nutrient media

Published: December 2023

Abstract Cyathea corcovadensis and Cyathea phalerata are tree ferns native to Brazil, endangered in the state of Rio Grande do Sul. Spore germination and gametophyte development in media with different nutrient formulations and activated charcoal were evaluated, aiming to develop a process for obtaining plants of the two species. Spores were sown in four semi-solid culture media: Meyer, Dyer, MS with 50% and MS with 25% of the original macronutrient concentration. For each medium, 10 replicates were carried out (flasks with 5 mg of spores/30 mL of medium), with and without 1% activated charcoal, respectively. Spore germination and gametophytic development (laminar and cordate stages) were quantified at 30, 60 and 90 days of culture. Cyathea corcovadensis and C. phalerata germinated and developed gametophytes in all media. For both species, the highest percentages of germination and cordate gametophytes (more advanced development stage) were recorded in Meyer medium without activated charcoal, which has higher concentrations of macronutrients and no micronutrients compared to the other evaluated media. We recommend cultivating the plants in Meyer medium for greater gametophytic development and subsequent sporophyte obtention, as a biotechnological tool for C. corcovadensis and C. phalerata conservation and for environmental restoration and enrichment using these tree ferns.

Abstract Tijuca National Park (TNP) covers an area corresponding to 3.5% of the city of Rio de Janeiro. It is an Atlantic Rainforest fragment with peaks and watersheds that make this protected area a mosaic of habitats. It is composed of four subunits: Serra da Carioca, Pedra Bonita and Pedra da Gávea Inselbergs, Tijuca Forest, and the Pretos Forros/ Covanca Considering the importance of conserving biodiversity in rainforest fragments, such as those found in Tijuca National Park and its subunits, we analyzed the spatial distribution of species in relation to climatic factors that could impact species richness. In addition to floristic analysis, we provide details of endemism, conservation status, substrate and habitat preferences, as well as data on geographic distribution patterns for each species. Precipitation during the wettest month was shown to be one of the most important climatic features in the study area and may be related to floristic richness and composition. The TNP holds about 38.5% of known species in the state of Rio de Janeiro with 254 taxa distributed in 26 families and 83 genera. Floristic richness can be impacted by environmental variables, including climatic factors. Our results show that relating floristic richness to environmental variables can be a way to understand biodiversity.

Published: December 2023

ABSTRACT Environmental degradation from human pressures includes the conversion of native vegetation cover into pastures and cropland, as well as riparian deforestation, leading to river siltation, biotic homogenization, and loss of ecosystem services. The objective of our study was to evaluate water quality and benthic macroinvertebrate assemblage structure in response to changes in land use at local and buffer spatial extents. We assumed that human disturbances negatively affect water quality and macroinvertebrate assemblage condition. Greater human influence was observed at the local extent (Local Disturbance Index – LDI) than at the buffer (Buffer Disturbance Index – BDI) extent. Likewise, biological metric responses were stronger relative to the LDI than to the BDI or to the Integrated Disturbance Index (IDI). These results support establishing a biomonitoring program for assessing water body quality in the Doce River basin to facilitate conserving aquatic biodiversity and ecosystem services in the upper Graipu River.
As doenças do Brasil segundo Valter Hugo Mãe
Authors: Santos Josalba Fabiana dos
Published: December 2023

RESUMO: O objetivo deste trabalho é analisar As doenças do Brasil (2021), do escritor português Valter Hugo Mãe. O romance se desenvolve em torno dos Abaeté, etnia indígena ficcional. Em pleno período colonial, os Abaeté não vivem em paz, pois estão acossados pelos portugueses, que desejam usurpar suas terras e submeter seus corpos. Nossa análise se baseará na ecocrítica, corrente da Crítica Literária que estuda expressões artísticas que se ocupam do meio ambiente em todo o planeta, sem distinção de fronteiras. No entanto, a maior contribuição ao nosso trabalho advém de dois pensadores indígenas: Davi Kopenawa (2010) e Ailton Krenak (2019). Pretendemos considerar, ainda, alguns aspectos referentes à ética e à estética a partir das ideias de Murcho (2015) e Hermann (2005).
