Published: August 2022

Introducción. Los libros de texto constituyen uno de los principales objetos de estudio de la historia de la educación en tanto que depositarios de la ideología del grupo del que emanan y reflejo de los significados que configuran la cultura escolar. Por otra parte, los movimientos de pedagogía musical crítica apuestan por la utilización de un repertorio vinculado a las identidades y preferencias musicales del estudiantado. Desde esta perspectiva, este artículo de investigación presenta un estudio sobre la evolución del repertorio musical en los libros de texto de música en educación primaria en la provincia de Valencia desde 1994 hasta 2019.  Metodología. Se han analizado 1121 piezas musicales pertenecientes a 18 manuales mediante el análisis de contenidos. Resultados. Los resultados indican una tendencia hacia una mayor diversidad musical, aunque con un predominio de la música clásico-romántica y folklórico-tradicional y una escasa representación de la música popular urbana. Discusión. La progresiva inclusión de música popular urbana en los libros de texto podría servir para reconocer y dar voz a las identidades musicales del estudiantado. No obstante, dicho repertorio es muy heterogéneo y no necesariamente tiene que incluir las preferencias musicales actuales.
Effect of Atomic Substitutions on the Electronic Structure of Pt1 – xNixMnSb Alloys (x = 0.0–1.0)
Authors: Uvarov V.N. , Uvarov N.V. , Zagorodnii V.V. , Kruk A.S.
Published: August 2022

Using zone calculations in the FLAPW (the full-potential linearized augmented-plane-waves) model, the information on the energy, charge, and spin characteristics of Pt1-xNixMnSb alloys (x = 0.0÷1.0) is obtained. It is established that, with an increase in the concentration of nickel atoms in Pt1-xNixMnSb alloys, the interatomic space density of electrons decreases, covalent bonds weaken, and the cohesive energies of the alloys decrease. The dominant contributions to the formation of magnetic moments in Pt1-xNixMnSb alloys are made by 3d electrons of manganese atoms. In alloys with x ≥ 0.50, the complete polarization of Fermi electrons is registered, which converts these alloys to a half-metallic state.

Published: August 2022

BACKGROUND AND OBJECTIVES

Children with medical complexity (CMC) with gastrostomy and jejunostomy tubes are commonly hospitalized with feeding intolerance, or the inability to achieve target enteral intake combined with symptoms consistent with gastrointestinal dysfunction. Challenges resuming feeds may prolong length of stay (LOS). Our objective was to decrease median time to reach goal feeds from 3.5 days to 2.5 days in hospitalized CMC with feeding intolerance.

METHODS

A multidisciplinary team conducted this single-center quality improvement project. Key drivers included: standardized approach to feeding intolerance, parental buy-in and shared understanding of parental goals, timely formula delivery, and provider knowledge. Plan-do-study-act cycles included development of a feeding algorithm, provider education, near–real-time reminders and feedback. A run chart tracked the effect of interventions on median time to goal enteral feeds and median LOS.

RESULTS

There were 225 patient encounters. The most common cooccurring diagnoses were viral gastroenteritis, upper respiratory infections, and urinary tract infections. Median time to goal enteral feeds for CMC fed via gastrostomy or gastrojejunostomy tubes decreased from 3.5 days to 2.5 days within 6 months and was sustained for 1 year. This change coincided with implementation of a feeding intolerance management algorithm and provider education. There was no change in LOS.

CONCLUSIONS

Implementation of a standardized feeding intolerance algorithm for hospitalized CMC was associated with decreasing time to goal enteral feeds. Future work will include incorporating the algorithm into electronic health record order sets and spread of the algorithm to other services who care for CMC.

Published: August 2022

The first life stage of crocodilians is considered the most critical in terms of survival, particularly in regions that have well-defined cold seasons. To estimate this parameter for hatchling broad-snouted caimans, Class I (CI = snout-vent length < 25 cm), we released 36 caimans (18 in 2018, and 18 in 2019) born in captivity that were equipped with VHF radio-transmitters, and we monitored them during each first winter season. We actively searched for the animals during field trips and registered their status as alive, dead, lost transmitter (LT), or radio signal ceased (SC). Due to the occurrence of LT and SC, we proposed eight possible survival scenarios, assuming different combinations of "alive" and "dead" caimans. We analyzed each scenario and compared it between years. In 2018 we found 55.5% dead and 44.5% LT, resulting in survival estimates from 0 to 0.38 according to the scenario. In 2019 we found 50% alive, 33% LT, and 17% SC, with survival varying from 0.5 to 1. Survival in 2019 was higher than in 2018 in all scenarios. Assuming predation was the most plausible cause of LT, with the most likely scenarios estimated 0% survival in 2018 (although the minimum detectable by this methodology is 5%) and 67% in 2019. This information can be helpful for ranching with release programs, as it allows for a better adjustment of the reintroduction rate and opens up the possibility of earlier releases when resources to keep animals in enclosures are scarce.

Published: August 2022

We analysed and monitored the major chemical composition of cow's bulk milk by Fourier transform mid-infrared (FT-MIR) spectroscopy over a 10-year period in the whole territory of Hungary. In addition, the two most important key parameters for milk quality assessment, total bacterial count (TBC) and somatic cell count (SCC) were also followed. Production parameters showed significant seasonal and yearly changes. The overall mean fat, protein, lactose and solids-non-fat (SNF) contents of cow's milk were 3.81%, 3.32%, 4.74% and 8.76%, respectively. A circannual variation was observed in the chemical composition and yield of milk components of samples examined between 2011 and 2020. Concerning milk fat, milk protein and SNF, the values were the lowest in summer and the highest in winter. In the case of lactose, the minimum values were measured in autumn and the maximum values in spring. An obvious trend of long-term elevation of lactose and SNF was found in the raw cow milk samples over the observed period. The overall mean TBC and SCC of cow's milk were 52 × 103 CFU ml−1 and 270 × 103 cells/ml, respectively. Although there were differences in the monthly average values, no seasonal cyclicality was observed.

Published: August 2022

The objective of the present pilot study was to determine the force required to break (a) intact canine tibiae, (b) tibiae following the osteotomy of the tibial tuberosity and (c) tibiae following Tibial Tuberosity Advancement- (TTA-) rapid surgery. Six pairs of tibiae of dogs between 15 and 35 kg body weight were used in a cadaver study. Three groups were created with four tibiae in each group; intact (Group 1), osteotomy of the tibial tuberosity and tibial crest (Group 2) and TTA-rapid (Group 3). The tibiae were put under static axial compressive load, applied until failure. The force required to break the tibiae was termed maximal force (F
max). The mean of F
max was 8193.25 ± 2082.84 N in Group 1, 6868.58 ± 1950.44 N in Group 2 and 7169.71 ± 4450.39 N in Group 3. The sample size was small for a statistical analysis but as a preliminary result, we have determined the force (F
max) required to break canine tibiae. Furthermore, we hypothesise that osteotomies result in weakening of the tibial structure.

The present case report describes the clinical signs of a 10-month-old, intact female, Domestic Shorthair cat presented with a history of chronic progressive difficulty to walk with the four limbs. The physical and neurological examinations revealed skeletal deformities, corneal opacity and a severe spastic non-ambulatory tetraparesis. Complete blood count and biochemistry profiles were unremarkable. Diffuse bone rarefaction, hyperostosis and an apparent fusion of the vertebral bodies were observed on spinal radiographs. A non-contrast computed tomography (CT) exam of the whole body of the patient was performed. Based on the medical history, clinical findings, laboratory analysis, spinal radiographs and CT findings, a lysosomal storage disorder was suspected. Genetic testing for mucopolysaccharidosis VI and VII revealed a genetic mutation, ARSB variant L476P, confirming the diagnosis of mucopolysaccharidosis type VI.

Published: August 2022

According to the extensive studies in the field of high-energy cathode materials for lithium-ion batteries (LIBs), Mn-based oxyfluorides Li1.2Mn0.6+0.5yNb0.2–0.5yO2–yFy with Li-excess and cation-disordered rock-salt structure capable of reversible cationic and anionic redox reactions are among the most promising candidates. In this work, a series of Mn-based oxyfluorides with y = 0.05, 0.10, 0.15 were obtained using mechanochemically assisted solid-state synthesis with different cooling rates. Transmission electron microscopy, electron paramagnetic spectroscopy (EPR) and nuclear magnetic resonance spectroscopy (NMR) show that increasing the amount of fluorine promotes local ordering in crystals with the formation of isolated clusters of Mn3+–O2––Mn4+ that interrupt lithium diffusion. The occurrence of local ordering depends on the conditions of synthesis and affects electrochemistry. It was found that more clusters are formed in slowly cooled samples than in quenched ones. The best electrochemical characteristics with reversible capacity of 150 mAh·g–1 at room temperature were demonstrated by the Li1.2Mn0.65Nb0.15O0.90F0.10 sample obtained by quenching.

Published: August 2022

Express determination of antibiotics is an extremely important task today. Portable electrochemical microdevices are a viable alternative to traditional methods of analysis. The development of such devices requires the study of redox processes in detail. This article is devoted to the comparative study of the electrochemical behavior of chloramphenicol in water solvents in standard laboratory and portable microelectrochemical cells. It was found that the electrochemical reduction of chloramphenicol proceeds via a 3-electron mechanism to the formation of a dimer. In the transition from the macrocell to the microcell, a decrease in the electrochemical reduction current and a shift of the peak potential to the cathode region are observed, which is apparently associated mainly with the type of the electrode material. The best characteristics of the direct electrochemical response were obtained in the differential pulse voltammetry mode. Under the selected operating parameters, the peak current of the electrochemical reduction of chloramphenicol is linearly dependent on the concentration of the antibiotic in the range of 2∙10–3–1∙10–5 M with a detection limit of 3∙10–5 M. Obtained characteristics are sufficient for the quality control of pharmaceuticals and can be improved through the use of organic and hybrid modifiers of the working electrode surface.

Published: August 2022

Este artigo discute a dinâmica do subsetor de Serviços de Apoio Diagnóstico e Terapêutico (SADT) no Brasil entre 2008 e 2016. Por meio de uma abordagem exploratória, a pesquisa buscou operacionalizar conceitos-chave na literatura sobre o padrão de acumulação que caracteriza o capitalismo contemporâneo. A pesquisa investigou a atuação de seis empresas de diagnósticos brasileiras em três dimensões principais: (1) patrimonial; (2) contábil-financeira; e (3) política. Os resultados mostram um subsetor em franco crescimento, via aumento do volume e dos preços de serviços comercializados. As evidências corroboram traços de um padrão de acumulação financeirizado, notadamente estratégias agressivas de fusões e aquisições por parte de empresas líderes e, como resultado, a centralização. Algumas outras características associadas ao conceito de financeirização, porém, parecem não ter relevância. Discute-se ainda o horizonte concorrencial nas atividades do subsetor de SADT e seus possíveis efeitos para o esforço de consolidação do Sistema Único de Saúde (SUS).

ABSTRACT BACKGROUND: Nonalcoholic hepatic steatosis is found in most obese patients and has a strong association with metabolic syndrome. The Roux-en-Y gastric bypass and the sleeve gastrectomy are the two techniques of bariatric surgery. Patients who underwent bariatric surgery have regression of nonalcoholic steatohepatitis due to a reduction in body mass index and changes in incretin hormones. AIMS: This study aimed to analyze the acuity of elastography in the regression of hepatic steatosis and fibrosis in obese patients undergoing Roux-en-Y gastric bypass and sleeve gastrectomy 2 months after surgery. METHODS: Patients in the preoperative period of bariatric surgery underwent an anthropometric evaluation and hepatic elastography to quantify fibrosis and hepatic steatosis. Two months after surgery, the same evaluation was performed again. RESULTS: All 17 patients who met the inclusion criteria participated in the study. Out of this, nine underwent sleeve gastrectomy, and eight underwent Roux-en-Y gastric bypass. The Roux-en-Y gastric bypass group had lower fibrosis levels postoperatively compared to preoperatively (p=0.029, p<0.05). As for steatosis, patients who underwent Roux-en-Y gastric bypass had lower postoperative values (p=0.01, p<0.05). There was also a reduction in fibrosis postoperatively in the sleeve gastrectomy group compared to preoperatively (p=0.037, p<0.05). CONCLUSIONS: Elastography accurately demonstrated decreased hepatic steatosis and fibrosis in the early postoperative period of bariatric surgery. Moreover, Roux-en-Y gastric bypass and sleeve gastrectomy are suitable surgical methods to improve hepatic steatosis and fibrosis within 2 months postoperatively.

Abstract Proanthocyanidin (PA) is a promising dentin biomodifier due to its ability to stabilize collagen fibrils against degradation by matrix metalloproteinases (MMPs); however, the most effective protocol to incorporate PA into bonding procedures is still unclear. This study evaluated the effect of dentin biomodification with a PA acid etchant on MMP activity, adhesive interface morphology and resin-dentin microtensile bond strength. Sound extracted human molars were flattened to expose dentin and acid-etched for 15 s according to the groups: EXP - experimental phosphoric acid; EXP+PA - experimental phosphoric acid 10% PA; TE - total-etching system; SE - self-etching system. Samples were restored with composite resin and stored in distilled water (37ºC). MMP activity and interface morphology were analyzed after 24 h by in situ zymography (n=6) and scanning electron microscopy (n=3), respectively. The resin-dentin microtensile bond strength (μTBS) was evaluated after 24 h and 6 months storage (n=6). Significantly higher MMP activity was detected in etched dentin compared with untreated dentin (p<0.05), but no difference among acid groups was found. Resin tags and microtags, indicative of proper adhesive system penetration in dentinal tubules and microtubules, were observed along the hybrid layer in all groups. There was no difference in μTBS between 24 h and 6 months for EXP+PA; moreover, it showed higher long-term μTBS compared with TE and EXP (p<0.05). The results suggest that 15 s of biomodification was not sufficient to significantly reduce MMP activity; nonetheless, EXP+PA was still able to improve resin-dentin bond stability compared with total- and self-etching commercial systems.

Published: August 2022

Abstract This study aimed to evaluate the influence of the number of dentists in the neighborhood on the incidence of dental caries in the children permanent dentition. This cohort began in 2010 (T1) with a random sample of 639 children (1 to 5 years-old) followed for 7 years, in southern Brazil. The follow-up reassessment (T2) took place in 2017. Untreated dental caries was evaluated at T2 through the Decayed, Missing, and Filled surfaces index (DMF-S). The number of dentists in the neighborhood was obtained from the city’s official database and used as a contextual variable. Socioeconomic, demographic, and oral health variables at the individual level were evaluated at T1. A multilevel Poisson regression was performed to evaluate the influence of the predictor variables in the incidence of untreated dental caries. From 639 children at T1, 449 were reassessed at T2 (a 70.3% retention rate). The mean of decayed surfaces at T2 was 0.92 (SE 0.01). The greater the number of dentists in the neighborhoods where the children lived, the lower the incidence of dental caries. Children with low socioeconomic status, who have not routinely visited the dentist in the last 6 months, who presented a experience of dental caries, and whose parents perceived their oral health as fair/poor showed a higher incidence of surfaces with untreated dental caries. As conclusion, children who live in neighborhoods with fewer dentists have a higher incidence of untreated dental caries in permanent dentition.

Published: August 2022

Abstract This study aimed to evaluate the association between the severity of hypomineralized second primary molars (HSPM), molar-incisor hypomineralization (MIH) and dental caries in children. 450 children between the ages of 6 and 7 years were included in this cross-sectional study. A calibrated examiner classified the enamel hypomineralizations and dental caries lesions using the MIH and HSPM and the Nyvad criteria, respectively. The primary outcome was the severity of MIH according to the severity of HSPM. Statistical analysis was performed using the generalized linear model and ordinal logistic regression. The prevalence of concomitant MIH and HSPM was 26% sex and age adjusted. Mild enamel defects were more frequent than severe enamel defects. An association was found between the severity of MIH and HSPM, both for mild defects (OR=87.54; 95%CI: 55.87, 137.17) and severe defects (OR=82.15; 95%CI: 45.72, 147.61). The severity of hypomineralization in permanent molars was associated with the activity of dental caries lesions (OR=29.85; 95%CI: 12.95, 68.83). To conclude, there is a strong association between the severity of HSPM and MIH, which is more significant in the presence of active dental caries lesions.
A computational modeling method for root canal endoscopy using a specific CBCT filter: A new era in the metaverse of endodontics begins
Authors: Bueno Mike R , Estrela Carlos
Published: August 2022

Abstract A contemporary technological revolution has started a new era in the metaverse of Endodontics, a world of virtual operational possibilities that use an exact replica of the natural structures of the maxillofacial complex. This study describes a modeling method for root canal endoscopy using modern cone-beam CT (CBCT) software in a series of clinical cases. The method consists in acquiring thin CBCT slices (0.10mm) in the coronal, sagittal, and axial planes. A specific 3D volume filter, the pulp cavity filter of the e-Vol DX CBCT software, was used to navigate anatomical root canal microstructures, and to scan them using root canal endoscopy. The pulp cavity filter should be set to synchronize CBCT scans from 2D mode - multiplanar reformations (MPR) - to 3D mode - volumetric reconstruction. This filter, when adopting the option of volumetric reconstruction, the developed algorithm leaves the dentin density in transparent mode so that the pulp cavity may be visualized. The algorithm applied performs the suppression (visual) of areas with dentin density. This ensures 3D visualization of the slices and the microanatomy of the root canal, as well as a dynamic navigation throughout the pulp cavity. This computational modeling method adds new resources to Endodontics, which may impact the predictability of root canal treatments positively. The virtual visualization of the internal anatomy of an exact replica of the canal ensures better communications, reliability, and clinical operationalization. Root canal endoscopy using this novel CBCT filter may be used for clinical applications together with innovative digital and virtual-reality resources that will be naturally incorporated into the principles of Endodontics.

ABSTRACT Introduction: Reduction of spinopelvic mobility is associated with an increased dislocation of total hip arthroplasty (THA). Objective: To assess 1) spinopelvic mobility in patients with primary hip osteoarthritis and THA indication and 2) the influence of hip flexion contracture on spinopelvic mobility. Methods: Thirty adult patients with primary hip osteoarthritis and THA indication were evaluated using radiographic parameters (pelvic incidence, pelvic tilt, sacral slope, lumbar flexibility, and spinopelvic mobility). Results: Spinopelvic mobility ranged from 6.90 a 54.50° (mean 32.79 ± 11.42) and the group of patients with hip flexion contracture had higher mobility. Spinopelvic mobility was correlated with pelvic tilt as well as with lumbar flexibility. Conclusion: Around 13.4% of patients had spinopelvic mobility under 20° , indicating reduced spinopelvic mobility and risk of THA dislocation. Level of Evidence III, Retrospective Comparative Study.

ABSTRACT Objective: This research sought to carry out a comparative study observing the clinical and radiographic analysis of primary prostheses of the type TC3 Depuy Johnson® with or without a stem during a short-term follow-up. Methods: The sample was divided into three groups: Group 1 (with stem), Group 2 (without stem) and Group 3 (mixed). Patients were evaluated to assess whether the implants were loosening and a clinical analysis was performed. Results: Preoperative deformities were predominantly considered severe. The total range of motion in the postoperative period was above 96.7° in the three groups. In the postoperative period, the femoral-tibial angle oscillated on average between 5 to 6° valgus. There was no record of implant loosening for cases treated with stem, and the incidence of loosening was 14.3% for the group without stem and 16.7% among cases in the mixed group. Conclusion: In general, preoperative deformities were considered severe. In the postoperative period, the total range of motion was above 96.7°. The postoperative femoral-tibial angle obtained an average of 5 to 6° valgus. There is no significant difference in implants loosening in the three groups.

ABSTRACT Objective: To assess the impacts of measures to face COVID-19 on total knee arthroplasty procedures in the country, based on data provided by the SUS Information and Informatics Department (DATASUS). Methods: Cross-sectional study of secondary data in the public domain, available on the website of the Department of Information and Informatics of SUS (DATASUS), containing information about hospital admissions in the SUS. Results: Brazil suffered a 51.82% decrease, on average, in the performance of total knee arthroplasty by the Unified Health System (SUS) in 2020, due to measures to face COVID-19. The analysis by region offers more details on this reduction in the number of procedures. In the Northeast, the decrease was on average 48.02%, whereas in the Center-West it was 65.61%. Southeast, North, and South registered an average decrease of 49.38%, 51.81%, and 55.06%, respectively. Conclusion: COVID-19 impacted the realization of TKA in Brazil, with greater and lesser levels of decline observed in different Brazilian regions. In the Southeast region, for example, the states of São Paulo and Minas Gerais were the most affected, mainly due to the large population concentration, as well as Paraná, which has high numbers of procedures and a sharp decrease in 2020.

Revisiting postverbal standard negation in the Jê languages
Authors: Auwera Johan van der , Krasnoukhova Olga
Published: August 2022

Abstract In the Jê languages standard negators tend to take a post-verbal position. This paper asks why this should be the case and therefore discusses earlier accounts relating Jê standard negators to either negative verbs or privative postpositions. We argue that these accounts do not have to exclude each other. In particular, we propose that an existential negator can be reanalyzed as a privative one. We also argue that if the origin of the standard negator is a verb with the meaning ‘finish’, we may be dealing with a scenario that is similar to the ‘Negative Existential Cycle’. In both, the existential negator denies the existence of a state of affairs and then turns into a standard negator. But whereas in the Negative Existential Cycle the non-existence of a state of affairs is modelled on the non-existence of an object, in the ‘new’ scenario the non-existence of a state of affairs derives from the fact that a process or event has come to an end.
Huguenotes, ingleses, abacaxis: associativismo abolicionista e escravizados nas rotas de fuga entre Pernambuco e Ceará na década de 1880
Authors: Souza Felipe Azevedo e
Published: August 2022

RESUMO Huguenotes, ingleses e abacaxis são termos que foram empregados por abolicionistas para ocultar a identidade de pessoas escravizadas que escaparam do cativeiro por rotas de fuga entre a Zona da Mata pernambucana, o Recife e os quilombos abolicionistas no Ceará. O artigo aborda a montagem de uma rede abolicionista interprovincial no início da década de 1880 e a intensificação das fugas de escravizados entre 1884 e 1888, observando em particular a atuação clandestina e radical do Clube do Cupim, bem como alguns aspectos relacionados à construção de sua memória no pós-abolição. O Clube se destacou em relação às associações abolicionistas do período pela diversidade social de seus membros e pela capacidade de promover a articulação de trabalhadores livres pobres, libertos e escravizados em operações que desarticularam o escravismo na região.
Engenheiros do Grande Mar Redondo: engenharia e natureza nas baías de Paranaguá e Antonina (1871-1879)

RESUMO A construção de uma ferrovia entre o litoral e a capital paranaense gerou conflitos entre os engenheiros brasileiros, pois as elites políticas locais reivindicavam a estação portuária e o traçado da ferrovia. Considera-se que os engenheiros eram experts que, segundo Bruno Latour (2004), manejavam os processos técnicos transitando entre a ciência e a política. O artigo analisa a atuação destes engenheiros na configuração espacial do litoral do Paraná, buscando compreender os projetos de engenharia no conjunto das relações entre a sociedade e a natureza. A pesquisa foi desenvolvida a partir da análise dos relatórios técnicos dos engenheiros e conclui-se que, a partir de uma ciência positivista, os engenheiros legitimaram os anseios dos grupos políticos que idealizavam a modernização e o progresso da província.
Entre subalternas e anfitriãs: a complexa relação entre as mulheres e a História
Authors: Mendes Ana Luiza
Published: August 2022

RESUMO O presente artigo tem como objetivo analisar a obra de arte de Judy Chicago, The Dinner Party, à luz dos conceitos desenvolvidos pela História das Mulheres. Tal relação se dá por meio da interpretação da obra a partir do contexto no qual ela foi concebida, a da segunda onda do movimento feminista, que contribuiu para o desenvolvido da História das Mulheres como um campo teórico. Os estudos inseridos na História das Mulheres, todavia, não se limitam a apenas apontar para a existência das mulheres ao longo da história, mas também suscita o questionamento sobre o motivo e como se dá o seu apagamento. A obra de Chicago, rica em simbolismos, foi escolhida por encerrar esses vieses presentes nesses pressupostos epistemológicos conectando a afirmação de identidades, a recuperação de memórias e a releitura de uma história definida pelo gênero.
A emergência histórica do lazer revisitada
Authors: Dias Cleber
Published: August 2022

RESUMO O artigo analisa criticamente as conclusões mais recorrentes acerca da história do lazer, assunto que se articula, de maneira mais geral, com a economia política e com a formação do capitalismo contemporâneo. Por meio de uma ampla revisão, o artigo questiona ideias muito difundidas de que a Inglaterra do século 19 teria sido a época e o lugar para uma aguda e inédita transformação nas formas de organizar os tempos e as recreações. Não obstante as mudanças que de fato estavam ocorrendo nessas instâncias naquele contexto, o artigo argumenta que antigos hábitos persistiram e que as transformações nessa esfera foram lentas e graduais, além de estarem social e regionalmente concentradas. Além disso, transformações análogas também eram registradas, na mesma época, fora da Inglaterra. A ênfase na singularidade das transformações na Inglaterra, portanto, além de controversa, dado que dependiam de acontecimentos desenrolados em outros lugares, é produto de um viés nacionalista e etnocêntrico.

Published: August 2022

ABSTRACT Purpose To search the literature for guidelines on infant’s audiological monitoring, most commonly used procedures, the age at which they are performed, which population should be monitored and the countries that study the subject the most. Besides, the importance and effectiveness of these measures will be discussed. Research strategy The review was conducted based on the PRISMA recommendations, registered on the PROSPERO platform. The studies were searched for in the electronic databases Medline (Pubmed), Web of Science and SciELO, using the descriptors hearing, neonatal screening and follow up. Selection criteria studies reporting the audiological monitoring were included. No filters on year and language of publication were used. Results A total of 432 articles were found and 21 were included in this study, mostly produced in developed countries. The Auditory Brainstem Response and the Behavioral Assessment were the most frequently used procedures. As to age and population, most infants are subjected to audiological monitoring up to three years of age and have Risk Factors for Hearing Loss in their clinical history. Conclusion The studies pointed that there is no standard among the protocols for performing audiological monitoring, but it was possible to identify agreement as to the age at which such monitoring takes place and which population should be monitored. However, although there is some disagreement, the assessment methods used in the studies are effective in detecting mild, progressive and/or late hearing loss, in addition to false negative cases.

Published: August 2022

Abstract Different strategies are used by people with cancer to deal with the various events resulting from this condition, among which, spirituality/religiosity is an important aspect to be considered. In this article, we present the results of a research that aimed to understand how patients with cancer and in palliative care experience spirituality/religiosity in the treatment process and how this dimension manifests itself in coping with the disease. The qualitative research with phenomenological orientation was carried out in a hospital in the city of Belém-PA and involved six patients diagnosed with cancer admitted to the Oncology Palliative Care Clinic - CCPO. The data was obtained through semi-directed interviews recorded in audio, later transcribed and analyzed according to Ricoeur's hermeneutics from units of meaning. The main results point to spirituality/religiosity as a coping strategy in the face of the state of illness and hospitalization. This dimension is evident in the routine of patients who maintain involvement in individual and collective religious activities during treatment. The religious experience in the hospital environment proved to be a way to face the illness process and a device through which individualized strategies are created to minimize suffering.

Abstract Introduction Occupational therapists are dedicated to the education service sector, however, this sector has had difficulties in advancing its universal accessibility, with a growing number of young people out of school, harming their condition of inclusion and social participation. Objective To map the production of scientific knowledge associated with occupational therapy, schools and youth, to answer the following questions: 1. How have occupational therapists contributed to youth in schools? 2. What proposals have these professionals disseminated in this context? Method A systematic mapping review carried out on the Scopus and Web of Science databases, which retrieved 46 publications covering from 1979 until 2019. Results Occupational therapists have not prioritized young population in their practices and studies. Noteworthy are the work to support young people with disabilities leaving high school, studies on mental health and an increasing number of works involving young people in situations of social vulnerability. Conclusion There is a need to increase and disseminate occupational therapy actions related to young people in schools, fostering theoretical and practical subsidies that offer better contours to this professional insertion.
Imaginação, racionalidade e educação: bases da criação e do conhecimento
Authors: Corbiniano Simone
Published: August 2022

Resumo Refletir acerca da imaginação significa pensar o próprio problema da vida criadora. Sob a perspectiva contemporânea significa ainda discutir a permanente elaboração de um novo psiquismo no qual o espírito se dispõe à abertura, ao conhecimento, que ao final é sempre um autoconhecimento. Resultante de pesquisa na área da Educação – tendo como referencial teórico-metodológico a Filosofia – este artigo propõe-se a estudar as bases conceituais da imaginação na modernidade e sua importância para a educação. Diferente do pensamento da ciência clássica, que compreende a imaginação como representação de um objeto percebido, o filósofo francês Bachelard a compreende no sentido oposto à formalização lógico-empírica da imagem, haja vista que para ele a imaginação se apresenta como instância das imagens que ultrapassam a realidade. A imaginação tem grande relevância na formação humana e na educação escolar, sendo um fator ativo de transformações que participa tanto da esfera da liberdade e da criação quanto do plano epistemológico do conhecimento e da ciência, planos esses que, embora de modos diferentes, se relacionam em seu ponto de partida com a imaginação e a fertilidade das imagens primordiais. Pode-se dizer que na educação, como em toda atividade humana, a realidade imaginária é evocada antes de ser descrita, pondo em questão o vigor da criação, o reencontro com a juventude da imaginação ativa. A natureza livre e dinâmica da imaginação é indispensável para a formação comprometida com o alargamento do espírito, cujo princípio é a livre invenção do espírito humano.
