Published: December 2024

ABSTRACT Introduction: The Karnofsky Performance Status (KPS) is one of the most widely used tools for assessing the prognosis of oncology patients, providing an estimate of treatment efficiency and survival. Despite this, it is commonly used in free translations without validation. The objective of the present study was to perform the cross-cultural adaptation of the KPS instrument to Brazilian Portuguese (KPS-BR) through the stages of conceptual, semantic, operational, measurement, and functional equivalences. Methods: To assess consistency, we used Cronbach’s alpha and kappa coefficients. The Chi-square test was performed to evaluate the association between scores and the number of deaths. The relationship with survival and mortality was explored with Kaplan-Meier curves. Results: A total of 316 patients participated in the study. The internal consistency analysis resulted in a Cronbach’s alpha coefficient of 0.9265. For the inter-rater analysis, the correlation coefficient was 1, as was the kappa coefficient, indicating perfect agreement between observers. The correlation coefficient between the KPS-BR scale in the test-retest was 0.8631. We observed a 100% death rate at KPS-BR scale score 20 and a gradual decrease as the KPS-BR scale score increases up to KPS-BR 40 (p<0.0001). Estimation of survival using the Kaplan-Meier method demonstrated an association between KPS-BR scale scores and survival (p<0.0001). Conclusion: The KPS-BR scale showed reliability and validity for the prognostic assessment of cancer patients, demonstrating a correlation with survival.

ABSTRACT BACKGROUND: There is recent evidence showing that obesity is associated with gastroesophageal reflux disease and esophageal dysmotility, although symptoms are not always present. AIMS: This is a prospective study based on high-resolution manometry findings in bariatric surgery candidates and their correlation with postoperative dysphagia. METHODS: Manometric evaluation was performed on candidates for bariatric surgery from 2022 to 2024. The examination was conducted according to the protocol of the fourth version of the Chicago Classification, including different positions and provocative maneuvers to confirm the diagnosis of dysmotility. Patients were followed for 90 days after surgery to verify the occurrence of dysphagia or difficulty adapting to the diet. RESULTS: High-resolution manometry was performed on 46 candidates for bariatric surgery with a mean body mass index of 46.5 kg/m2. Esophagogastric junction outflow obstruction was diagnosed in 16 (34.8%) patients, and ineffective esophageal motility was diagnosed in 8 (17.4%) patients. None of the subjects reported symptoms during the preoperative period. Out of the 46 individuals initially included, 44 underwent bariatric surgery, 23 (52.3%) underwent Roux-en-Y gastric bypass, and 21 (47.7%) underwent sleeve gastrectomy. One patient with esophagogastric junction outflow obstruction reported dysphagia after Roux-en-Y bypass, but symptoms spontaneously resolved during the 90-day follow-up period. CONCLUSIONS: Although patients with severe obesity have a high prevalence of esophageal motility disorders, no clinical repercussions were observed after bariatric surgery during the study period.
Entre o fortalecimento institucional e tendências de precarização da força de trabalho: orçamento e emprego público no Poder Judiciário (1986-2021)
Authors: Pacheco João Pedro
Published: December 2024

Resumo: Neste trabalho, trato da reestruturação institucional do Poder Judiciário no Brasil desde a volta à democracia. Para tanto, analiso como tem sido a gestão de suas despesas e de sua força de trabalho nas últimas três décadas. Os resultados apontam que, com o fim do período autoritário, o Judiciário recuperou sua autonomia e independência, o que resultou em seu fortalecimento institucional, evidenciado no incremento orçamentário e no aumento e modernização de sua força de trabalho. Entretanto, na última década, apesar de ganhos financeiros acima da inflação, tem havido redução em seu quadro de pessoal efetivo e crescimento de força de trabalho sem vínculo. Tal fato indica que, possivelmente, esteja havendo uma precarização da força de trabalho do Poder Judiciário no Brasil.

Abstract The aim of this study was to evaluate the effects of long-term alendronate administration on bone repair and mineralization around osseointegrated implants in rats. A total of 160 female Wistar rats were randomly assigned to two groups: the control group (CTL) and the alendronate group (ALD). The ALD group received a subcutaneous injection of sodium alendronate (1 mg/kg/week), while the CTL group received weekly injections of saline solution. After 120 days of treatment, a bilateral implant was placed in the tibia of each rat. Ten rats from each group were euthanized at 5, 10, 15, 20, 25, 30, 45, or 60 days post-surgery. Picro-sirius red staining was utilized to assess the distribution and arrangement of collagen fibers near the implant threads. Bone mineralization mapping of the native bone adjacent to the implant was performed using images obtained through scanning electron microscopy (SEM) across all follow-up periods. SEM-based mineralization mapping revealed an increase in both the degree and homogeneity of bone mineralization in the ALD group compared to the CTL group. Alendronate administration affected collagen arrangement and distribution, leading to a connective tissue with reduced organization and thinner collagen fiber bundles. In conclusion, the findings demonstrated that alendronate administration resulted in a higher degree and homogeneity of bone mineralization, accompanied by reduced collagen content and organization, suggesting an impairment in bone remodeling around dental implants.

Abstract Root canal retreatment and fracture of fiberglass posts (FGP) can require the FGP removal. The aim of this study was to evaluate the effect of the FGP removal protocol on the time for FGP removal (min), the root dentin removed (mm3), the angle alteration of the root canal alignment (o), and the root perforation occurrence using cone-beam computed tomography (CBCT) analysis. Thirty extracted maxillary molars were randomly assigned to 3 groups (n = 10): Mic-Ult, FGP removed using ultrasonic inserts under microscopic magnification; Mic-DiB, FGP removed using diamond burs under microscopic magnification, and Endo-G, FGP removed using Endo-G. CBCTs were made after access opening and after FGP removal. The volume of root dentin, the root canal alignment and root perforation were performed using InVesalius and Mimics softwares. Root canal angle alteration after FGP removal was performed using ImageJ software. The time for FGP removal was calculated in min. Data were analysed by one-way analysis of variance was followed by Tukey HSD test (α = 0.05). Endo-G resulted in significantly lower root dentin removal (p< .001), and significantly less time than Mic-Ult and Mic-DiB (p< .001). Mic-DiB had 1 and Mic-Ult had 2 root dentin perforations. FGP post removal using Mic-Ult and Mic-DiB exhibited significantly greater alteration in the root canal alignment than that using Endo-G (p< .001). FGP removal using Endo-G exhibited better preservation of the original canal alignment, saved root dentin structure, and also required less time compared to FGP post removal using Mic-DiB or Mic-Ult under microscopic magnification.

Abstract Autophagy is a self-digestion mechanism of cells, which is related to cell stress. It enables cell survival by maintaining cellular homeostasis or initiates cell death. This study aimed to investigate the intracellular signaling of pressure-induced autophagy regulation in human periodontal ligament (PDL) cells and to analyze the involvement of Rho kinases (ROCK) and reactive oxygen species (ROS) in particular. Human PDL cells were treated with the ROCK inhibitor Y-27632 and the ROS scavenger N-acetylcysteine (NAC) in combination with pressure magnitudes of 2, 6, and 8 g/cm2 over 16 hours. Cells treated with rapamycin served as a positive control and untreated cells as a control group. The Cyto-ID® Autophagy Detection Kit was used for flow cytometric analysis. Statistical analysis was performed using ANOVA and post-hoc tests. The results show that the pressure-induced autophagy was affected differently by the two inhibitors (p<0.05). The application of Y-27632 led to a significant reduction in autophagy in all pressure groups. The application of NAC led to reduced autophagy at pressures of 2 g/cm2 and 6 g/cm2. At 8 g/cm2, this effect was no longer present. In the control group, autophagy was significantly reduced by Y-27632 and significantly increased by NAC. Our data suggest that both Rho-kinase and reactive oxygen species could influence pressure-induced autophagy regulation in PDL cells.

Abstract The present study explored the association between the craniofacial sagittal skeletal patterns and frontal sinus dimensions in Germans. This cross-sectional study included orthodontic patients with age ranging from 11 to 18 (80 males, 82 females). Lateral cephalograms were used in the cephalometric and frontal sinus analysis. Cephalometric analysis was performed to measure SNA, SNB and ANB angles. Frontal sinus measurements were performed to obtain the frontal sinus height, antero-posterior dimension and frontal sinus lateral projection area. The frontal sinus dimensions were compared between genders with Mann Withney test. Kruskal Wallis and Dunn's post-hoc tests were used to compare the mean differences between the skeletal malocclusions. Spearman’s correlation test and linear regression model were also performed. Statistical significance was set at 5%. Regarding skeletal malocclusion, 71 patients presented class I, 81 class II and 10 class III skeletal malocclusion. The frontal sinus height (p=0.009), frontal sinus antero-posterior dimension (p=0.001) and frontal sinus lateral projection area (p=0.007) were bigger in males than in females. The frontal sinus antero-posterior dimension was significantly greater in the class III when compared to the class I (p=0.010) and class II (p=0.027). Frontal sinus lateral projection area was also bigger in class III than class I (p=0.039). In the linear regression model a significant association was observed between frontal sinus lateral projection area and class III (skeletal class I as a reference). In conclusion, our result suggests that the frontal sinus lateral projection area might present morphometric differences in German teenagers with skeletal class III malocclusion.

ABSTRACT: Ensilage of rehydrated corn kernels (RC) has been used to improve nutritional value and facilitate on-farm storage. This study evaluated the effects of chitosan and lactic acid microbial inoculants on rehydrated corn silage microbiology, fermentation profile and losses, chemical composition, in vitro degradation, and aerobic stability. Forty experimental silos were used in a completely random design to evaluate the following treatments: 1) Control (CON): RC silage without additives; 2) Chitosan (CHI): RC silage with 6 g/kg dry matter (DM) of chitosan; 3) Lactobacillus buchneri (LB): RC ensiled with 5 × 105 colony forming units (CFU) of L. buchneri per gram fresh weight; and 4) Lactobacillus plantarum and Pediococcus acidilactici (LPPA): RC ensiled 1.6 × 105 of L. plantarum and 1.6 × 105 P. acidilactici per gram fresh weight. Additives increased lactic acid bacteria and concentration of lactic and propionic acid, decreased mold and yeast count and gas and fermentative losses, and improved DM recovery. The CHI-silos had lower silage pH, Ammonia-N concentration, fermentative losses, and higher acetic acid concentration compared to microbial inoculated-silos. In addition, CHI and LB decreased silage pH and temperature after aerobic exposure. Although, treatments showed slight effects on the nutritional value of RC, CHI improved aerobic stability and decreaseds fermentation losses.

Published: December 2024

ABSTRACT: Echinacea angustifolia is a perennial plant that has been traditionally used to treat various microbial diseases. This study evaluated the in vitro antiviral properties of an ethanolic extract of E. angustifolia against bovine alphaherpesvirus 1 (BoHV-1). BoHV-1 infection is associated with respiratory, reproductive and neurological disease in cattle, resulting in major economic losses. When cells were treated with E. angustifolia extract at a non-cytotoxic concentration at different times (3, 6 or 24 hours) before BoHV-1 inoculation, no viral detection was possible after 72h, while in untreated cells the virus reached a titer of 105.5TCID50 /25µl (median). Incubating the extract with BoHV-1 24 hours before cell inoculation did not result in loss of viral infectivity. Cells infected with 103 TCID50 of BoHV-1 and not treated with E. angustifolia showed an average of 45.8% viability after 48 hours of infection, while 91.1% remained viable when treated 6 hours after or 84.1% 24 hours after infection, demonstrating a significant reduction in the cytopathic effect. In addition, E. angustifolia significantly reduced the relative mRNA expression of the antiviral cytokines IFNα and IFNβ in the treated cells, suggesting that the antiviral activity is not due to immunomodulation. The obtained data indicated that the ethanolic extract of E. angustifolia may directly interfere with virus attachment, entry, and/or egress from infected cells. Taken together, the presented data emphasized the promising antiviral activity of E. angustifolia against BoHV-1.

Published: December 2024

ABSTRACT: Evaluated different feed forms (FF), (mash or pellets), feeding systems (FS) (ad libitum or controlled) and metabolizable energy levels (ME) (2,900 kcal/kg or 2,750 kcal/kg) in rearing period 1 (7 to 12 weeks) and 2 (13 to 17 weeks). Utilized 400 brown-egg laying pullets a completely randomized design in 2x2x2 factorial arrangement (eight treatments, with five replications). In period 1, feed intake was similar (P > 0,05) between FF and between ME, however pullets fed ad libitum showed 27.5% higher intake than fed with controlled amounts (P < 0,05). Body weight (BW) differed (P < 0.05) in the FS. Feed conversion (FC) was not affected (P > 0.05) by any of the study factors. Flock uniformity was affected (P < 0.05) by FF and by FS, with an interaction between the factors (P < 0.05). The pullets fed the mash feed ad libitum had better uniformity (P < 0.05) than the pullets fed with the controlled mash feed. The pelleted feed caused the worst uniformity. In rearing period 2, feed intake was affected (P < 0.05). That pullets fed mash or pelletized feed ad libitum consumed 8g more (P < 0.05) on average, than those in the controlled FS. In the ad libitum supply, intake was higher (P < 0.05) for the mash feed than for the pelleted feed. BW and FC were not affected by any of the factors (P > 0.05). Uniformity (%) was influenced by the mash or controlled systems (P < 0.05). Between 7 and 17 weeks of age, brown-egg laying pullets need to be fed with a mashed diet in a controlled feeding system, with 2,750 kcal/kg of metabolizable energy.

Published: December 2024

ABSTRACT: New teaching tools can expand the pedagogical alternatives for teaching comparative anatomy. This study evaluated the potential of Styrofoam waste for the manufacture of viable didactic models to teach comparative anatomy. From a primary block, the sculpting was started with a knife or cutter. After this, the edges were removed with sandpaper until the final anatomical shape of the organ was obtained. The surface of the sculpture was then covered with paper soaked in an aqueous solution of white glue. After drying, a layer of resin was applied, followed by polishing to even out the surface. The models are finished with paint and waterproof sealant. Through the teaching prototypes, it was possible to enlarge naturally small organs and structures to larger dimensions that favor practical teaching. This facilitates the didactic approach to anatomical details unavailable in traditional specimens. In addition, its use minimizes the risks to human health from exposure to the toxic products used to preserve cadavers and contributes to preserving the environment. The effectiveness of injected resin models for teaching anatomy is already known, which makes the use of synthetic anatomical models a valid methodology, but they may have limitations in many countries due to their high cost and difficulty of access. Our proposal offers an effective, low-cost alternative for teaching comparative anatomy in practice. When combined with other techniques, Styrofoam waste proved to be viable for the manufacture of teaching prototypes.

Abstract The experiment was conducted at the Department of Plant Pathology, Bangladesh Agricultural University, Mymensingh to identify T. asperellum in a countrywide screening program and to evaluate its antagonistic effect against several soil borne pathogens. Samples were collected from the rhizosphere soil of 49 different crops in 107 different locations in Bangladesh, especially, considering the several isolates of T. asperellum for purification. Based on morphological and physiological features, fifteen isolates were selected. Of these, the isolates of TR27 and TR45 were grown and sporulated at 40 °C except all the isolates with 35 °C, and particularly, showing a decrease of mycelial growth across all the isolates for increasing pH. Meanwhile, T. asperellum showed significant antagonistic effects against Fusarium oxysporum, Sclerotium rolfsii and Pythium aphanidermatum, resulting in reducing foot and root rot, collar rot and damping off diseases, respectively. Four isolates were selected for molecular characterization among 15 isolates in terms of higher mycelial growth and spore density in-vitro condition, isolates of (TR27) Sadar, Moulvibazar (Rice), (TR45) Sadar, Mymensingh (Sweet gourd), (TR70) Chapra, Chapai Nawabganj (Sesame) and (TR85) Nayanpur, Lalmonirhat (Maize) were studied at ITS and TEF region. Isolates of TR45, TR70 and TR85 were observed with 98% homology, and TR27 exhibited 88% in their respective closest isolates at ITS sequences. Isolates of TR27 and TR85 also exerted their respective nearest homology (96%), while TR45 showed 99%, and 93% homology with TR70 in TEF sequences. Isolates TR45, TR70 and TR85 were evidently determined as T. asperellum of 100% bootstrap value, and TR27 isolate was also recognized with 72% bootstrap value in the phylogenetic tree. However, complementary effects of significant superior homology and the greatest bootstrap value in the identification of T. asperellum were found as noteworthy. In the phylogenetic analysis, magnificent differentiation among the Trichoderma isolates within and among the groups of closely related species was observed in Tef1 region than reflecting maximum variability in the isolates of rDNA at ITS region, whereas demonstrating a higher transversion ratio and evolutionary divergence.

Published: December 2024

Abstract The reproductive ecology of a species is a key focus of conservation planning efforts as it offers insights into how the species persists and adapts to its environment. The Yellow-Spotted River Turtle, Podocnemis unifilis (Troschel,1848), has a wide distribution within the Amazon region and is generalist in its nesting site choice. Monitoring the nesting habits of this turtle is essential to understand the resilience of its populations and to evaluate the impact of environmental disruptions. This study aimed to assess how environmental factors affect the hatching rate, nest loss, and sex ratio of P. unifilis in the Iriri River, Pará. In 2012 and 2013, we monitored 121 nests over approximately 200km of the river within the Terra do Meio Protected Area. Nests with deeper egg chambers located at high elevated areas of the beaches had a higher mean hatching rate. Moreover, deeper nests had fewer rotten eggs and were less infected by Sarcophagidae fly larvae. Animals predated only two nests, and humans collected five nests. Nests that were manipulated presented lower hatching rates compared to unmanipulated nests. Furthermore, the sex ratio 100% biased towards females may indicate the limit of the behavioral and physiological plasticity of the species. Compared to other areas, P. unifilis nests had deeper egg chambers in the Iriri River, likely due to climate and nesting site granulometric profile. Our findings suggest that females of P. unifilis adjust nest characteristics to maximize the survival of their offspring in this coarse sediment environment. The plasticity in nesting site selection and nest depth highlights the species’ ability to adapt, enabling it to occupy a wide geographic area and successfully reproduce in various environments. However, climate change may gradually alter this situation, emphasizing the need to gather reproductive data from different sites to monitor the species’ capacity to adapt to habitat alterations.
Accessing the sand fly diversity of Tocantins, Northern Brazil: species delimitation using COI DNA barcoding
Authors: Soares Ocléia de Sousa Rodrigues , Rodrigues Bruno Leite , Shimabukuro Paloma Helena Fernandes
Published: December 2024

Abstract Sand flies (Diptera, Psychodidae, Phlebotominae) are considered natural vectors of infectious agents, such as viruses, bacteria and protozoa. About 1,060 species are recognized, of which 73 have been recorded in the state of Tocantins, located in the transition of Amazon and Cerrado biomes, Northern Brazil. Here, we surveyed the sand fly fauna in different environments of the municipality of Palmas, including caves. Also, we evaluated a fragment of the cytochrome c oxidase subunit 1 (COI) as reliable for species delimitation in this region. The morphological identification of 163 sand flies revealed the presence of 26 species distributed in 13 genera. Of these, Lutzomyia itambe, Deanemyia samueli, Pintomyia gruta, Psathyromyia barretti, and Sciopemyia servulolimai had not yet been recorded in the state of Tocantins, thus, the sand fly fauna of the state is composed of 78 species. The first DNA sequence of Edentomyia sp., were generated, and probably correspond to an undescribed species, and new studies are needed to verify their real taxonomic identity. Also, eight nominal sand fly species were COI-sequenced for the first time, improving the DNA repositories for molecular species identification. The use of COI DNA barcodes proved to be efficient for identifying sand fly species in the state of Tocantins and revealed the existence of cryptic diversity for Nyssomyia whitmani and Psathyromyia aragaoi which need further investigations using an integrative taxonomy approach. However, COI sequences was ineffective in delimiting species of Evandromyia (Aldamyia) and Psychodpygus Chagasi series, and our limited sampling should be evaluated in more robust datasets to check the real usefulness of DNA sequences in identifying sand flies.

ABSTRACT: Respiratory diseases are responsible for economic losses in the poultry sector. The occurrence of coinfections can aggravate the severity of clinical signs and lesions, such as coinfection with Avibacterium paragallinarum and Gallibacterium spp. The aim of this study is to describe the epidemiological, clinical and pathological aspects of an outbreak of respiratory disease in laying hens caused by a coinfection by A. paragallinarum and Gallibacterium spp. in the state of Sergipe, northeastern Brazil. High morbidity and mortality were observed, accompanied by apathy, anorexia, serous nasal discharge and a decrease in egg production (approximately 10%). Five laying hens were selected for general clinical examination and euthanized. Samples of nasal turbinates, infraorbital sinuses, trachea, liver and spleen were collected, fixed in 10% buffered formalin and routinely processed for histopathology. For the microbiological examination, the whole heads of the birds were collected, packed in Nasco® plastic bags, stored at -8°C then sent to a private laboratory for bacterial isolation on Petri dishes containing blood agar and incubated at 37°C in microaerophilic. Grossly, there was a bilateral increase of periorbital volume with complete obstruction of nasal turbinates due to the presence of caseous exudate. Microscopically, there was marked diffuse chronic necrocaseous and granulomatous rhinitis, marked diffuse chronic granulomatous and heterophilic necrotizing sinusitis, focally extense lymphohistiocytic and heterophilic tracheitis with epithelial hyperplasia, loss of cilia and atrophy of mucous glands. In the microbiological examination, A. paragallinarum and Gallibacterium spp. were identified, and it was concluded that these agents were responsible for the outbreak of rhinitis and sinusitis in the studied birds.

Published: December 2024

Abstract Purpose: The rise of Revolution 4.0 raises several research questions; in the field of leadership, it could not be different. One of the most prominent issues in this field revolves around the attributes required of leaders in the context of Revolution 4.0. Therefore, this study sought to capture and measure the perception of Brazilian researchers and executives about the main attributes required of leaders in the digital age. Originality/value: The study is relevant as it sheds light on the skills required of leaders in the digital age, identifying important attributes for effective leadership. Design/methodology/approach: At first, an extensive literature mapping was carried out, resulting in a theoretical model of the Digital Leader around four dimensions: i) relational; ii) focus on people; iii) digital; iv) innovation and adaptability. Subsequently, quantitative research was applied to 77 executives and 14 researchers who published the most about leadership in Brazil. Findings: The results reveal a high perception of importance for all attributes identified in the research model. Therefore, for both executives and researchers, the individual able to lead in Revolution 4.0 must have attributes linked to the relational, human, digital, and innovation dimensions. However, when comparing the dimensions, it is verified that the digital dimension appears with a lesser degree of importance. It is curious that in Revolution 4.0, skills more related to technology occupied the least privileged position. This finding raises questions related to the recent discussion around the need for a new leadership style in the context of Revolution 4.0.

Abstract The studies on the forest sector focus on energy issues and environmental challenges, but they are limited to a small number of studies focused on economic growth and social welfare. In the forest sector, Brazil is among the five countries with large forest cover in the world, with favorable conditions and great potential for production growth. Therefore, this work aimed to measure the evolution of efficiency and productivity of the 49 Brazilian forestry microregions in converting the expansion of economic growth into social welfare from 2009 to 2015 (a period of sectoral growth in the country). The approach of the Slack-Based Measure (SBM) – Data Envelopment Analysis (DEA), Malmquist Productivity Index (MPI), and Windows Analysis model was combined, followed by a solution for infeasibility problems. The results show that the growth of the forestry sector was not accompanied by the Human Development Index (HDI) in most of the microregions, showing regional and state differences, with the microregions close to the sensitive environmental areas with the lowest HDI. Thus, the work contributes to the design of public policies and government decision-making to increase the sector's efficiency and productivity and to social indicators that can guide sustainable policies in other contexts and countries.

Published: December 2024

Resumo No Brasil, a soja representa 29,4% do valor bruto da produção agropecuária. Todavia, essa cultura enfrenta diversas intempéries climáticas. Nesse sentido, o seguro agrícola emerge com o propósito de mitigar esses desafios, porém sua expansão é dificultada por problemas como a seleção adversa e os riscos sistêmicos que afetam os resultados das seguradoras. Nesse sentido, o objetivo deste artigo é analisar os fatores que afetam a lucratividade das seguradoras agrícolas no estado do Paraná, no período de 2007 a 2021, por meio da regressão de dados em painel, a qual possibilita a análise de dados de várias unidades, como municípios e empresas, ao longo do tempo. Observou-se que a área segurada, a produtividade efetiva e a variável dummy indenização constituem os principais fatores determinantes da lucratividade das seguradoras tanto na modalidade de custeio como na de produtividade. Entre as empresas analisadas, apenas a Brasilseg e a Mapfre apresentaram resultados negativos, enquanto a Newe, uma empresa iniciante, teve resultados positivos. As contribuições do estudo incluem a compreensão detalhada dos fatores que afetam a lucratividade das seguradoras agrícolas e o fornecimento de informações úteis para o aprimoramento da gestão de riscos e para a formulação de políticas, contribuindo para a sustentabilidade e a competitividade do setor.

Abstract Introduction The impact of aligners in the periodontal conditions and protocols for hygiene were investigated. Objective This study assessed the periodontal condition of patients undergoing orthodontic treatment with ClearCorrect aligners and compare periodontal health conditions after the use of BlueM mouthwash and foam as clinical protocols for oral and aligner hygiene. Material and method In 16 patients’ treatment was performed using aligners, and a periodontal follow-up was conducted. The sample was divided into 3 randomized groups: Control, Mouthwash, and Foam, with each patient passing through all groups. The use of a standardized toothpaste was indicated. A periodontal examination was performed on baseline and every 2 months using gingival sulcus probing, insertion level, recession, bleeding on probe index, and biofilm presence. Result Significant differences were observed in distal probing of the teeth when comparing baseline and the mouthwash group in the intergroup analysis, irrespective of the side of the mouth and the tooth evaluated. When assessing bleeding on probe, baseline showed 1.8 times more risk of bleeding on probe than foam, 1.9 times more risk than the control, and 2.4 times more than mouthwash group. Regarding biofilm presence, baseline data showed 1.4 times more risk of having biofilm than foam, and 1.9 times more risk than mouthwash groups. In relation to the control, there was no statistically significant difference. Conclusion Patients when using BlueM mouthwash had a lower chance of bleeding on probe and presence of biofilm, as well as an improvement in distal periodontal probing depth when compared to baseline situation.

Authors: Oliveira Elisa Fabris de , Bonomo Mariana , Rosa Edinete Maria
Published: December 2024

Abstract The aim of this study was to identify and understand the social representations of university quotas published in Carta Capital and Veja Brazilian magazines between 2008 and 2017. A total of 199 texts were analyzed, which showed that ideological bias acted as a metasystem to promote dissent in the understanding of the object under investigation. In comparison, Carta Capital’s social representations were based on the notion of fairness and social equality, while Veja’s texts approached university quotas as a partisan, unfair and non-meritocratic measure. The research was exploratory-descriptive in nature and used analysis supported by the Iramuteq software and the societal approach of the Theory of Social Representations.

Published: December 2024

ABSTRACT Objective: To map the scientific production of perioperative nursing aimed at adolescents. Method: A scoping review based on JBI guidelines and recommendations from the Preferred Reporting Items for Systematic Review and Meta-Analyses for Scoping Reviews. The search took place between February and March 2023 in 05 databases and in gray literature. Results: Nineteen studies were included, 13 articles and 6 works from gray literature. The results demonstrated the importance of systematizing nursing care for adolescents with actions that aim to include them in care and prepare them for their surgical trajectory with a view to reducing anxiety and respecting individualities. Actions such as the use of integrative and complementary therapies, insertion of educational technologies and adaptation of the environment for neuroatypical adolescents were also identified. As a gap, there is a lack of studies specifically aimed at adolescents, encompassing their care for the pediatric population. Conclusion: The scoping review mapped studies produced by nursing on perioperative care for adolescents and indicated the use of strategies to individualize care, reduce perioperative anxiety and promote engagement and involvement of surgical patients. It is necessary to expand the number of studies and interventions that are specific to adolescents.

ABSTRACT Weed control is a challenge in crop management due to the limited number of registered herbicides, especially for preemergent application. This study aimed to investigate the selectivity of pre-emergent herbicides with different mechanisms of action for wheat. The experiment consisted of two stages: the first involved screening under greenhouse conditions, and the second assessing the selected treatments under field conditions, with a focus on crop yield. Plant phytointoxication, crop stand, and shoot dry weight were assessed in the greenhouse experiment, and tillering, crop stand, plant height, canopy closure, yield, 1000-grain weight, and hectoliter weight in the field. Under greenhouse conditions, [imazapic + imazapyr], pendimethalin, isoxaflutole, florpyrauxifen, and halosulfuron-methyl produced the best results and were selected for the field experiment. Florpyrauxifen was the only herbicide that was selective both in greenhouse and field experiments. Isoxaflutole and trifluralin did not damage wheat in any of the field evaluations. Despite reducing crop performance in some assessments, pendimethalin and flumioxazin provided yield, hectoliter weight, and 1000-grain weight results equivalent to the herbicide-free control. Florpyrauxifen (1.08 g ha-1) was the most promising herbicide. Trifluralin (900 g ha-1), pendimethalin (1750 g ha-1), isoxaflutole (60 g ha-1), and flumioxazin (40 and 60 g ha-1) also produced grain yields equivalent to the control without herbicide.

ABSTRACT Ascorbic acid is a non-enzymatic compound with antioxidant action in the detoxification of reactive oxygen species in plants subjected to abiotic stress conditions. Therefore, the objective of this study was to evaluate gas exchange, photochemical efficiency, and growth of guava cv. Paluma under water replacement levels and foliar application of ascorbic acid in the post-grafting phase. The experiment was carried out under greenhouse conditions, at the Center of Technology and Natural Resources, at the Federal University of Campina Grande, in Paraíba, PB, Brazil. A randomized block experimental design was used, in a 2 × 4 factorial arrangement, whose treatments resulted from the combination of two factors: two levels of irrigation water (50 and 100% of actual evapotranspiration - ETr) and four concentrations of ascorbic acid - AsA (0, 30, 60, and 90 mM), with three repetitions. Irrigation with a 50% ETr depth reduced the growth in rootstock diameter, scion diameter, and scion volume, as well as gas exchange: stomatal conductance, transpiration, and maximum and variable fluorescence indices of guava cv. Paluma. Ascorbic acid concentration of 90 mM increases the CO2 assimilation rate and instantaneous water use efficiency and reduces electrolyte leakage in the leaf blade of guava plants, 240 days after transplanting.

ABSTRACT Salinity is an abiotic factor that impairs the growth and physiological, biochemical, and molecular mechanisms of plants. Among plants, soybeans are an important crop worldwide, so managing abiotic factors is essential to mitigate plant damage. However, biostimulants, such as melatonin, are being employed to alleviate the stress caused by these factors. Therefore, this study aimed to evaluate the growth, photosynthetic pigments, and water relations of soybean plants subjected to salinity levels and exogenous melatonin application. The research was conducted in experimental area belonging to the Federal Rural University of the Semi-Arid Region, Mossoró, RN, Brazil. The experimental design was randomized blocks, arranged in a 3 x 3 factorial scheme (three salinity levels in the irrigation water - 0.50, 3.00, and 5.00 dS m-1 and three melatonin concentrations - 0, 0.5, and 1 mM) with three replications. At 47 days after planting, plant height, stem diameter, number of leaves, root length, chlorophyll content (a, b, and total), relative water content, leaf moisture, and electrolyte leakage were evaluated. Soybean plants tolerated the effects of salinity on growth aspects, photosynthetic pigments, and water relations up to 3.00 dS m-1, regardless of melatonin concentration. Exogenous application of melatonin mitigated the effects of salt stress on chlorophyll b and relative water content at salinity level of 5.00 dS m-1 and concentration of 1 mM.
