Background. Early diagnosis of thrombocytopathies in children is a relevant objective of pediatrics. Diagnostics helps prevent the development of bleeding, chronic posthemorrhagic anemia, reduces the risk of thrombosis.

The aim of the study is an assessment of the incidence of platelet aggregation disorders in children with manifestations of hemorrhagic syndrome against the background of chronic pathology.

Methods. The study was conducted on the basis of the Research Institute of Pediatrics and Children’s Health, Scientific Center No. 2, Petrovsky National Research Centre of Surgery in the period from January — until December 2022. 62 children were included in the study, of which 50 children were selected (21 boys and 29 girls) aged 2 years 3 months to 17 years 11 months. The median age was 9.4 (7.2; 13.4). Aggregometry was performed using an impedance semiautomatic aggregometer in whole blood.

Results. Depending on the diagnosis, the children were divided into the following groups: cardiovascular diseases (CVD), lysosomal storage disorders (LSD), monogenic hereditary diseases (MHD), children with dysplastic syndrome (DS), children with pathology of the nervous system (NS). Hypoaggregation with thrombin-activating peptide (TRAP test) was detected in 28% of cases (n = 14), more often in children from the group with MHD — 10% (n = 5) and with the presenceof DS — 10% (n = 5). Hypoaggregation with adenosine diphosphate (ADP test) was detected in 20% of cases (n = 10), with arachidonic acid (ASPI test) was detected in 14% (n = 7). Hyperaggregation with the TRAP test was detected in 12% (n = 6), with the ADP test detected in 8% of cases (n = 4). Hyperaggregation with ASPI test was detected in 18% of cases (n = 9).

Conclusion. The analyzed results of laboratory tests of platelet aggregation function, hypoaggregation with inducers was observed in more than half of the children, hyperaggregation was observed was present in almost half of the patients.

Hormone-producing ovarian tumors in girls are an actual problem in modern gynecology, which is associated with certain difficulties in managing patients. Firstly, it is worth taking into account the higher anatomical mobility of tumors in girls than in adults, due to the high location of the ovaries, weakness of the ligamentous apparatus and the active lifestyle of the child, which causes a higher incidence of torsion of the volumetric mass in children. Secondly, surgical treatment of hormone-producing ovarian tumors leads to a decrease in ovarian reserve and irreversible consequences in the reproductive health of patients in the future, which is an extremely undesirable complication in childhood. Therefore, methods of fertility preservation should be discussed with girls and their parents. It is also important to note that hormone-producing ovarian tumors have a certain degree of malignancy and a tendency to recur. Thus, the relevance of this topic lies in the complexity of management of pediatric patients with this pathology due to the clinical features of the course and a higher probability of complications. Hormone-producing ovarian masses should also include follicular cysts and corpus luteum cysts, but the above structures are excluded from the discussion in this article.

Published: February 2024

Heart failure (HF) is an urgent public health problem worldwide. A fundamental role in HF progression is played by fibrosis, which causes structural myocardial and vascular changes. In this regard, it seems relevant to search for pathogenetically justified HF therapy, aimed at slowing the myocardial fibrosis progression. The results of EMPA-REG OUTCOME study showed that glucose-lowering drugs, namely sodium-glucose cotransporter 2 (SGLT2) inhibitors, have a positive effect on HF course, reducing cardiovascular mortality and hospitalization rate of patients for decompensated HF. Large-scale studies showed the antifibrotic properties of SGLT2 inhibitors. The review article presents the results of experimental studies on the use of SGLT2 inhibitors in animals. A number of mechanisms for the implementation of the antifibrotic properties of SGLT2 inhibitors affecting the cardiovascular system have been described. It seems relevant to further study SGLT2 inhibitors in clinical trials in order to identify and correct the pathogenetic mechanisms of myocardial fibrosis.

Published: February 2024

The problem of rational management of patients with heart failure (HF) remains extremely relevant due to its increasing incidence and poor prognosis. Based on current guidelines, therapy for patients with HF involves systematic and long-term use of many medications, and their effectiveness largely depends on the quality of the patient’s compliance. Pharmacotherapy of older patients with HF is complicated by metabolism and the coexistence of many diseases associated with polypharmacy, which significantly reduces the response to therapy. Insufficient adherence to treatment has been proven to reduce the quality of life of patients. Currently, three HF phenotypes have been identified, depending on the left ventricular ejection fraction. However, the number of studies examining the characteristics of patient adherence in different phenotypes is limited, which requires further research. The article is an analytical review devoted to various aspects of adherence to treatment in patients with HF. The terms and concepts associated with compliance, the history of its research, the main modern approaches to pharmacotherapy of HF for different phenotypes are briefly covered. The results of a number of large clinical studies are presented, including the assessment of adherence in patients with HF and its relationship with prognosis.

Published: February 2024

Despite widespread knowledge in the management of patients with lipid metabolism disorders, their application in clinical practice is insufficient. Identification of barriers to the implementation of key principles of clinical guidelines in routine practice is the first step of the implementation study.

Aim. To assess the organization and quality of care for patients with dyslipidemia in order to identify barriers to the implementation of the main principles of clinical guidelines in practice.

Material and methods. An implementation study was planned, the initial stage of which was to conduct an anonymous online questionnaire among health care representatives of various levels in all Russian subjects.

Results. The study involved 788 physicians, 124 heads of medical organizations and 48 chief freelance specialists from 84 Russian subjects. A wide range of barriers was identified: low availability of lipoprotein (a) testing (66,6% of physicians), coronary calcium index (79,4% of physicians, 71,8% of heads of a medical organizations, 79,2% of chief freelance specialists) and CT angiography (70,0% of physicians, 71,0% of heads of a medical organizations, 85,4% of chief freelance specialists). Lack of funds to manage lipid service (55,6% of heads of a medical organizations, 35,4% of chief freelance specialists). The key barrier to regular lipid-lowering therapy and achieving target low-density lipoprotein cholesterol (LDL-C) levels is lack of perceived need for treatment in patients (58,1% of physicians, 80,0% of heads of a medical organizations, 87,5% of chief freelance specialists), for PCSK9-targeted therapy — high cost (44,1% of physicians, 34,7% of heads of a medical organizations, 23,0% of chief freelance specialists). The possible fixed-dose combination therapy for dyslipidemia was positively perceived (59,7% of physicians, 42,0% of heads of a medical organizations, 35,4% of chief freelance specialists). Inclusion of innovative therapy in medicine assistance program will improve the situation in achieving target LDL-C levels (85,6% of physicians, 91,1% of heads of a medical organizations, 95,8% of chief freelance specialists).

Conclusion. A wide range of barriers to the implementation of clinical guidelines on lipid metabolism disorders into practice have been identified. Based on the results obtained, the second stage of the implementation study will identify strategies aimed at eliminating the identified barriers.

An important role in the development and evolution of hypertension in females is applied to sex hormones. Estrogen deficiency and hyperandrogenism, characteristic of periand postmenopause, are links in the pathogenesis of hypertension in this period of a woman's life and are accompanied by an increase in sympathetic nervous system activity, renin-angiotensin-aldosterone system activation, salt sensitivity, abdominal obesity and metabolic syndrome, left ventricle hypertrophy, left atrial dilatation with a high risk of atrial fibrillation, stroke and heart failure development. The paper discusses antihypertensive therapy during periand postmenopause, effectiveness and tolerability of different drug classes. Special attention is paid to the mechanism of action of selective I1-imidazoline receptor agonist moxonidine, which in women during this period both effectively reduces high blood pressure and has a beneficial metabolic effect, what is documents in studies of monotherapy, combined antihypertensive therapy with major classes and in combination with menopausal hormone therapy. The paper presents the joint expert opinion concerning above mentioned issues.

Patients after heart transplantation (HT) are at very high risk for cardiovascular disease. Protocols for the management of heart recipients include the initiation of lipid-lowering therapy (LLT), regardless of sex, age and origin of heart failure. Given drug interactions and the risk of post-transplant complications, the LLT possibilities are limited in the transplanted population. The paper presents first Russian experience of using siRNA LLT for the treatment of dyslipidemia in solid organ transplant recipients.

Aim. To analyze risk factors for sarcopenia in atherosclerosis involvement of target organs in patients with type 2 diabetes (T2D).

Material and methods. The study included 84 patients with T2D, divided into groups according to the 2019 criteria of the European Working Group on Sarcopenia in Older People (EWGSOP2). All patients were surveyed using a 36-item short-form health survey (SF-36), Sarcopenia and Quality of Life (SarQoL), Strength, Assistance with walking, Rise from a chair, Climb stairs and Falls (SARC-F), grip test, 4-meter walk test, bioelectrical impedance analysis, 24-hour blood pressure monitoring and cardiac ultrasound. Differences were considered significant at p<0,05.

Results. Patients with sarcopenia have lower levels of fat, muscle, cell mass, appendicular mass index, fluid, protein, and minerals. In the group with sarcopenia, higher levels of total cholesterol, low-density lipoprotein cholesterol, glycated hemoglobin, and hypocalcemia were detected. Triglyceride levels were high in those with presarcopenia. In the same group, unstable blood pressure, increased myocardial mass and severe lower limb atherosclerosis were recorded.

Conclusion. Sarcopenia is one of the important medical and social problems and is accompanied by unfavorable outcomes. The combination of sarcopenia and T2D can contribute to the rapid development of macro- and microangiopathy and increase the cardiovascular risk.

Published: February 2024

Aim. To evaluate any cardiovascular abnormalities in the postoperative period, their prevalence and impact on the course of postoperative period in patients after non-cardiac surgery, which underwent postoperative examinations of cardiovascular system.

Material and methods. The study included 2937 patients. The assessed end points were postoperative cardiovascular events (CVEs). Along with major adverse cardiovascular events (MACE), we analyzed any cardiovascular abnormalities in the postoperative period as follows: electrocardiographic ST-T abnormalities, acute or decompensated heart failure (HF), arrhythmias, episodes of hypotension or hypertension, bleeding, thromboembolic events (TEEs), cerebrovascular events, postoperative delirium. Any CVEs constituted the any cardiovascular events' (ACVEs) group. Statistical analysis was carried out using the StatTech v program. 3.1.6 (OOO Stattekh, Russia).

Results. Any postoperative complications according to the Clavien-Dindo classification were 54,7%, while grade 1 — 33,9%, grade 2 — 20,3%, grade 3 — 1 case, grade 4 — 0,4%, grade 5 — 0,1%. MACEs developed in 0,2% of cases. ACVEs amounted to 13,3%, including 2,3% — ST-T abnormalities, 6,3% — significant systolic blood pressure changes, 2,6% — arrhythmias, 0,7% — HF, 2,4% — bleeding, 1,1% — TEEs, 0,3% — delirium. In addition, 67 (17,5%) patients had ≥2 CVEs. Comparison of the length of hospital stay of patients with ACVEs, in particular with MACEs, ECG ST-T abnormalities, HF, arrhythmia, episodes of hypotension or hypertension, bleeding, TEEs, cerebrovascular events, delirium, with groups of patients without such complications revealed significant differences. ACVEs accounted for 1/4 of all postoperative complications and 2/3 of complications of grades 2-5.

Conclusion. We expanded the concept of CVEs, united the totality of any cardiovascular abnormalities in the postoperative period, emphasized not only their clinical significance, but also the economic feasibility of taking into account ACVEs.

Published: February 2024

Aim. To study the relationship between the amount of epicardial left atrial fat and left atrial mechanical dispersion (LAMD) in hypertensive patients with persistent atrial fibrillation (AF) and without cardiac arrhythmias.

Material and methods. The main group included 100 hypertensive patients with persistent AF, who underwent transesophageal echo cardiography (TEE) before the elective cardioversion, and transthoracic echocardiography (TTE) after cardioversion and disappearance of atrial stunning. The control group included 24 hypertensive patients without cardiac arrhythmias, who underwent TEE for other indication. The thickness of atrial septum and left lateral ridge was measured by TEE. The average thickness of these structures was designated as left atrial fat. The time to peak of longitudinal myocardial strain in 6 left atrium segments was determined by speckle-tracking echocardiography. LAMD was calculated as a percentage of the standard deviation of the obtained values to cardiac cycle duration.

Results. The median left atrial fat thickness in the main and control groups was 8,03 [6,78; 8,95] and 5,23 [4,48; 5,80] mm (p<0,0001), median LAMD — 2,68 [2,41; 2,83] and 0,95 [0,62; 1,11]% (p<0,0001). There was a positive correlation between left atrial fat thickness and LAMD in the main group (r=0,556; p<0,0001). This relationship did not reach the level of statistical significance in the control group, (r=0,358; p=0,0860). There was no independent relationship between body mass index and left atrial fat thickness in the patients (r=0,027; p=0,7651).

Conclusion. In hypertensive patients with persistent AF, compared with patients without rhythm disturbances, the average values of left atrial fat thickness and LAMD are significantly higher. The increase in left atrial fat thickness is associated with the increase in LAMD in hypertensive patients with AF. There was no correlation between left atrial fat thickness and LAMD in hypertensive patients without rhythm disturbances. There was no effect of body mass index on left atrial fat thickness in the present study.

Published: February 2024

Aim. To establish the prevalence and markers of masked hypertension (HTN) in apparently healthy young people.

Material and methods. The cross-sectional study included young people (20-30 years old) with health group I or II, with clinical blood pressure (BP) <140/90 mm Hg. All participants underwent 24-hour blood pressure monitoring, assessment of traditional cardiovascular risk factors and ways of coping with stress.

Results. A total of 347 participants were included (mean age, 22 (21-23) years; male, 101 (29,1%)). After 24-hour blood pressure monitoring, masked HTN was detected in 46 (13,3%) participants. Multivariate analysis found following markers of masked HTN: office systolic blood pressure (adjusted odds ratio (AOR) 1,109; p<0,001), resting heart rate (AOR 1,051; p=0,021), body mass index ≥25 kg/m2 (AOR 2,345; p=0,039), two models of coping with stress — distancing (AOR 1,071; p=0,001) and self-control (AOR 0,951; p=0,012). These parameters are included in the formula for calculating the masked HTN probability.

Conclusion. Masked HTN occurs in 13,3% of apparently healthy young people. Associations of masked HTN with strategies for coping with stress have been established, which allows them to be regarded as novel markers of masked HTN. The method described in the article makes it possible to identify masked HTN with a high probability in young people.
Desigualdade e acumulação de capital no capitalismo periférico
Authors: PREBISCH RAÚL
Published: February 2024

RESUMO O artigo argumenta que nos países em desenvolvimento as mudanças nas relações políticas e sociais assim como o progresso técnico criam uma tendência sistemática para um desequilíbrio dinâmico entre consumo e investimento. Nessas condições, a continuidade do crescimento requer uma política macroeconômica voltada para o aumento da taxa de acumulação por meio da redução do consumo agregado tanto das classes capitalistas quanto das classes trabalhadoras. Politicamente, esse tipo de política regulatória deve ser visto como uma oportunidade para a classe trabalhadora aumentar sua participação na propriedade da riqueza.

A circulação da ciência pode ser compreendida a partir da noção de rede, em que o conhecimento se difunde por meio de diferentes nós, caracterizados como heterogêneos, formados por especialistas e não especialistas, a partir dos quais ocorre um tráfego intercoletivo e multidirecional de pensamento, que também abarca transitoriedade.
From the field practice of Biology’s naturalistic tradition to the field days at school: distances and approximations
Authors: Silva Renata Priscila , Farias Carmen Roselaine de Oliveira , Muhle Rita Paradeda
Published: February 2024

Abstract This study has a theoretical and, to some extent, essayistic nature, as it embarks on an investigative and reflective journey that deviates from traditional methodological constraints. The goal is to encourage dialogue between the traditional naturalistic field practices and the field-based lessons in biology education. We use the field practices of traveling naturalists from the sixteenth century as a point of reference, aiming to establish an interpretive time horizon for contemporary field classes. By investigating the attributes and progression of field scientific practices, we can assess their impact on biology field courses and how they differ from them based on the specific circumstances. Making connections between science and teaching can help to break away from the daily grind of pedagogical routines and facilitate the necessary reevaluation of biology field lessons.

Resumo Este estudo tem natureza teórica e, de certo modo, ensaística, visto que se lança a um exercício investigativo e reflexivo livre das amarras metodológicas tradicionais para propor um diálogo entre as práticas de campo da tradição naturalista e as aulas de campo do ensino escolar de biologia. Tomamos como referência as práticas de campo dos naturalistas viajantes a partir do século XVI, no intuito de traçar um horizonte temporal interpretativo em relação às atuais aulas de campo. Ao apresentar as características das práticas científicas de campo e sua evolução, podemos analisar como as aulas de campo de biologia foram se constituindo, inspiradas nessas práticas e se diferenciando delas pelo contexto em que são desenvolvidas. Fazer correlações entre o campo da ciência e o do ensino pode contribuir para se tomar distância do cotidiano da prática pedagógica e propiciar a ressignificação necessária das aulas de campo em biologia.
Historical subjects and teaching from the perspective of Eduardo Coutinho: proposal for the training of history teachers
Authors: Perinelli Neto Humberto , Paziani Rodrigo Ribeiro
Published: February 2024

Abstract This paper presents reflections on the contributions made by Eduardo Coutinho’s conversation films to outline reflections associated with the concept of historical subject, to be addressed in the teaching of history. This research presents a qualitative approach, applied nature and explanation, using bibliographic analysis, document analysis and systematic observations, from an ex-post-facto perspective. Coutinho’s films feature women, the elderly, blacks, poor, peripheral and northeastern people, in order to treat their life experiences with significance. The pedagogical appropriation of these films is relevant for the construction of a training process that is guided by the approach of the historical subject from conceptions such as those of the excluded/subaltern/from below and which is aimed at teachers who teach History in Basic Education.
Syntheses of the appropriation of Vygotsky’s concept of Aesthetic Education in Brazilian art teaching (2006-2020)

Published: February 2024

Abstract The cultural-historical theory on human cognition, elaborated by the Russian researchers Vygotsky, Leontiev, and Luria between 1920 and 1930, reached psychology and education in Brazil from 1980 onwards, presenting a new dimension for the formation and performance of these professionals. Based on these assumptions, a systematic review of the Brazilian scientific literature between 2006 and 2020 was conducted, in search of articles published in areas of intersection between the psychology of education and art education, aiming to identify the circulation, reception, and appropriation of Vygotsky’s concept of aesthetic education. The results found are in line with studies that consider the concepts of “experience” and “environment” as essential for the understanding of cultural-historical theory.

Published: February 2024

ABSTRACT: The study examined the extent to which ethnic language use is influenced by strength of ethnic identity among university students in Malaysia. In the study, 100 university students from Malay, Chinese, Indian, and Indigenous ethnic backgrounds filled in a questionnaire on language use in six domains, and their ethnic identity was measured using Multigroup Ethnic Identity Measure (MEIM). English and Malay dominated in the mass media and education domains, and in intergroup and formal interactions, but ethnic languages were mainly used with family, friends and for religious practices. The results showed a moderate level of ethnic language use among the Malay (58.37%) and Chinese participants (59.21%), and a lower level among the Indigenous (49.55%) and Indian participants (42.11%). All four ethnic groups showed a positive ethnic identity. There is a significant positive relationship between the extent of ethnic language use and the strength of ethnic identity.
Leitura subjetiva e livros didáticos de Português: em busca do sujeito-leitor no ensino médio
Authors: Sá Ana Paula dos Santos de
Published: February 2024

RESUMO: O objetivo do artigo é verificar de que modo e em que medida livros didáticos de Português do ensino médio dão espaço à mediação de leituras subjetivas. Trata-se de uma investigação de viés documental e qualitativo, fundamentada em concepções dialógicas de leitura. O corpus é constituído por exercícios do eixo literário de coleções dos PNLDs 2015 e 2018, a partir das quais os dados foram mapeados, classificados e analisados. Os resultados apontam para a baixa incidência de questões de viés pessoal e para uma certa aleatoriedade na formulação dos enunciados das perguntas e dos gabaritos, que torna indistintas questões de viés objetivo e subjetivo. Conclui-se que, embora as coleções anunciem ao professor um alinhamento ao dialogismo, a abertura à expressão da pessoalidade do aluno apresenta inconsistências, pois há o predomínio de atividades que enfatizam um único modo de ler.

Published: February 2024

ABSTRACT: Internationalization (in general) and Englishization (in particular) are processes currently at work in a number of Brazilian universities. This article provides an account of ethnographic research into language policy processes unfolding in one federal university. Firstly, an analysis of the university’s internationalization plan is presented. This documentary analysis is then accompanied by an interpretation of the perspectives of key social actors on how the policy has been implemented in their context. I conclude by highlighting the need for there to be wider engagement between senior management teams and university personnel on different scales relating to the development and implementation of internationalization plans.

Published: February 2024

Abstract: Rice seeds have a dormancy which is understood as resistance to pre- and post-harvest germination. Thus, the present study aims to evaluate periods and temperatures in the pre-drying of rice seeds (cultivar IRGA 431 CL) to overcome dormancy. An experiment was carried out in a completely randomized design at the Didactic and Seed Research Laboratory, at the Federal University of Santa Maria. Three lots of the cultivar IRGA 431 CL were used. For the present study, temperatures of 35, 40, 45, 50 and 55 °C in a forced-air circulation oven were used to overcome seed dormancy. At each temperature the seeds remained for periods of 24, 48, 72, 96, 120, 144 and 168 h. First count, germination, and seedling root and shoot lengths were evaluated in the experiment. The data obtained were subjected to analysis of variance and compared by response surface. Temperature between 41 and 44 °C for a period of 95 h is more indicated to overcome dormancy in seeds of the IRGA 431 CL cultivar in a forced-air circulation oven.

Abstract: Seed treatments with chemical phytosanitary products can compromise mobilization of seed reserves for the seedlings under water deficit conditions. The aim of this study was to evaluate the physiological quality, the initial seedling development, and the mobilization of reserves in soybean seeds treated with phytosanitary products under water deficit. The trial was set up in a completely randomized design in a 4 × 4 factorial arrangement: chemical treatments (control, Thiamethoxam, Fludioxonil + Metalaxyl-M, and Fipronil + Pyraclostrobin + Tiophanate-methyl) × osmotic potentials (0, -0.1, -0.2, and -0.3 MPa). We analyzed the following variables: germination; hypocotyl length, root length, and total seedling length; seedling length vigor index; cotyledon dry matter weight; seedling dry matter yield; seed reserve reduction; relative dry matter yield; seed reserve reduction rate; and conversion efficiency of seed reserves into seedling dry matter. Seed quality and seedling development decline under water deficit conditions. The treatment with Fipronil + Pyraclostrobin + Thiophanate-methyl results in lower phytotoxicity. The estimated cotyledon dry matter (CDM) weight is an indicator of phytotoxicity and water deficit. Mobilization of reserves is compromised in seeds treated with insecticides, reducing the capacity of conversion of reserves into dry matter. There is an inversely proportional relationship between the reduction in conversion and the efficiency of conversion of reserves of treated soybean seeds under water deficit.

Abstract Introduction Since 2005, Brazilian cities have been adapting to organize teams and services of the Unified Social Assistance System (SUAS), and since 2011, occupational therapy has been recognized as one of the professions that compose these teams and the management of SUAS. This study addresses how the category has been involved in this policy in the state of Rio de Janeiro. Objective To map the occupational therapists working at SUAS in this state and outline the characteristics of this inclusion. Methodology A descriptive, cross-sectional mapping study, using official data from the SUAS Census. Data were analyzed from a descriptive perspective, in dialogue with the National Social Assistance/Welfare Policy, the literature in the field of occupational therapy in social assistance, and under the framework of social occupational therapy. Results In the State of Rio de Janeiro, 142 occupational therapists work at SUAS, which is equivalent to 8.9% of the professionals in this state. This workforce is composed of women (89.4%) aged 41-50 years (34.5%), hired by Civil Society Organizations (93%), under the Consolidation of Labor Laws (CLT) regime (50%), with a weekly workload of 11-20 hours (40.9%), mainly inserted in Day Centers (71%), working with people with disabilities and older people. Conclusion The inclusion of occupational therapists in SUAS of Rio de Janeiro state occurs precariously, with low insertion in this state’s devices. It highlights the need for representative entities of the class to act in this public policy as a promoter of expanding job opportunities/public contests/employment, as well as to invest in debates about team compositions and the recognition of different fields of knowledge.
Political action in occupational therapy: an integrative review
Authors: García Ruiz Solángel , Malfitano Ana Paula Serrata
Published: February 2024

Abstract Introduction Political actions are inherent to all everyday processes, both to maintain hegemony or to develop new projects in society. Objective To understand the discussions about political action referenced in the occupational therapy bibliography. Methodology An integrative review of the literature produced in the last five years, indexed by Web of Science, SciELO, Scopus and Lilacs databases, was carried out. The search equations “política” and “terapia ocupacional” were used in Spanish and in Portuguese; and “Occupational Therapy” and (politic OR policy OR policies), in English. The process was described according to the PRISMA proposal to relate identification, selection, and integrative analysis, as well as to propose documentary eligibility. Results The corpus consisted of 14 articles distributed in five journals, three of them from South America. It is evident that the discussions about political action have developed particularly in the South. The documents were analyzed under four categories: hegemony, resistance, tensions, and contradictions, present in the conceptual constructions and practices described. Two disputes about the political action of occupational therapists emerge: the first is related to the profession, and the second to the political place of the occupational therapist. Conclusion It is imperative to promote the construction of new hegemonies within professional actions, which are also political actions. Likewise, it is necessary to advance in epistemological, ontological, ethical, and political developments that support the proposed new common senses. Social occupational therapy in Brazil shows progress in this direction.

Abstract Introduction Early mobilization is an alternative used in the Intensive Care Unit (ICU) to reduce the effects of immobility. The Intensive Care Unit Mobility Score (IMS) is applied to assess mobility status. Objective To determine the functional level of ICU patients submitted to cardiac surgery using the IMS scale. Methods This is an analytical observational study carried out with adult ICU patients submitted to cardiac surgery. Data on the use of vasoactive drugs, functional level through IMS, duration of mechanical ventilation and length of ICU stay were collected from the physiotherapy routine form and recorded on a specific instrument developed for the study. The data obtained from the IMS scale score on the postoperative days in the ICU were used to classify the patients' mobility during the hospitalization period. Descriptive statistics were used to present the data. Results A total of 69 patients were evaluated, 43% of whom were men, and all had an SMI of 0 on the first postoperative day. Classification on the scale increased over the course of hospitalization (IMS between 7 and 10), despite the use of vasoactive drugs in 54.6% of the individuals. Conclusion Patients submitted to cardiac surgery admitted to the ICU had moderate-to-high mobility levels throughout their stay and at discharge from the ICU.
Antimicrobial resistance of bacterial agents of bovine mastitis from dairy properties in the metropolitan region of São Luís – MA
Authors: Brito Daniela Aguiar Penha , Costa Francisca Neide
Published: February 2024

ABSTRACT The objective of this study was to evaluate the “in vitro” antimicrobial susceptibility profiles of Staphyloccusspp. and Streptococcus spp. isolated from the milk of cows with infectious mastitis. This study was conducted on 14 dairy farms located in four municipalities on the Island of São Luís, Maranhão, Brazil. The isolates were obtained by bacteriological cultivation of milk samples, followed by morphological and biochemical characterization. Antimicrobial susceptibility tests were performed using the disk diffusion method. The results showed that none of the principles were 100% effective against the isolates. Penicillin, ampicillin, and amoxicillin showed higher rates of resistance in isolates of Coagulase-positive Staphylococcus (80%, 77.2%, and 77.2%, respectively), Coagulase-negative Staphylococcus (80%, 75.4%, and 75.4%, respectively ), and S. aureus (94.3%, 88.6%, and 88.6%, respectively). Isolates of Streptococcus showed a higher frequency of resistance to streptomycin (94%), tetracycline (86%), and lincomycin (76%). Isolates from the Coagulase-negative Staphylococcus group had the highest multidrug resistance profile, with 32.65% of the strains being simultaneously resistant to more than eight antibiotics. A high frequency of isolates of agents that cause bovine mastitis with multidrug-resistant phenotypes was determined, making it necessary to base the treatment of animals on the diagnosis of the causative pathogen and patterns of sensitivity to antimicrobials.
O ASPECTO GRAMATICAL NA LÍNGUA MEBÊNGÔKRE (KAYAPÓ): UMA INVESTIGAÇÃO NO QUADRO DA SEMÂNTICA FORMAL
Authors: Mendonça Junior Cledson
Published: February 2024

Este trabalho em andamento tem como objetivo investigar o aspecto gramatical na língua Mebêngôkre (Kayapó), falada por aproximadamente 2.120 pessoas em mais de 30 aldeias, na Terra Indígena Kayapó, em São Félix do Xingu, no Pará. Apesar de ser cooficial no município, há uma escassez de estudos que descrevam sua gramática, tornando essencial o desenvolvimento de metodologias de documentação, descrição e análise. A pesquisa concentra-se na distinção entre aspecto perfectivo e imperfectivo e os dados linguísticos foram obtidos por meio de elicitação controlada. A metodologia envolve testes de gramaticalidade, valor de verdade e felicidade. A análise do fenômeno é abordada sob a perspectiva da Semântica Formal e os resultados são relevantes tanto teoricamente para a ciência linguística quanto empiricamente para a comunidade Kayapó. Os testes buscam compreender como a língua Mebêngôkre marca gramaticalmente o aspecto verbal, através de auxiliares em posições fixas na sentença. Os resultados preliminares indicam que a expressão aspectual na língua ocorre por meio de verbos posicionais, posposições, expressões locativas e formas pronominais. A investigação inclui a análise de dados coletados por Mendonça Junior (2021) sobre o aspecto lexical na língua. A pesquisa contribui para a produção de materiais didáticos e de referência para o ensino da língua e sua implementação nas escolas municipais. Os resultados são promissores até o momento e fornecem subsídios teóricos e práticos para a ciência linguística e a comunidade Kayapó.
AS VOGAIS PRETÔNICAS DO KABUVERDIANU DO PRÍNCIPE
Authors: Freitas Shirley
Published: February 2024

Este trabalho enfoca o kabuverdianu do Príncipe e descreve suas vogais pretônicas, comparando-as com as tônicas. Como corpus para este estudo, foram utilizados dados coletados no Príncipe em 2018 e os pressupostos teóricos são a Fonética Acústica e descrições prévias do kabuverdianu de Santiago, ilha de procedência da maior parte dos migrantes (Carreira, 1983). As vogais pretônicas foram divididas entre orais e nasais. Os segmentos pretônicos orais encontrados foram [i, e, ɛ, ə, ɐ, a, ɔ, o, u], que, em comparação com as vogais tônicas, duram menos (com a diferença sendo em média 30 milissegundos) e são mais centralizados. Quanto às vogais com o traço nasal, não foi registrada a aplicação da nasalidade heterossilábica (com as consoantes [m] e [n] na sílaba seguinte), sendo encontradas as realizações [i, e, ə, ɐ, a, o, u]. Considerando a nasalidade tautossilábica, foram encontradas as realizações [ĩ, ẽ, ɛ̃, ə̃, ɐ̃, õ]. Das 20 ocorrências de pretônicas nasalizadas, em 17, o murmúrio se fez presente tanto diante de fricativas quanto de oclusivas. As vogais pretônicas nasalizadas tiveram uma duração maior do que suas contrapartes orais, o que, juntamente com a presença do murmúrio nasal, podem ser apontados como indicativos da natureza bifonêmica da vogal nasal (/VN/). Em suma, os dados analisados trazem novidades com relação às descrições de Santiago (como a presença de 3 vogais centrais), o que revela a importância de estudar diferentes variedades e contribui para um maior entendimento da realidade linguística do Príncipe.
Intersection optimisation study based on traffic conditions in the physical area

The contemporary prevalence of car ownership has presented urban intersections with burgeoning challenges in terms of motorisation and congestion. Traditional signal timing schemes often encounter difficulties in handling the resulting vehicle conflicts within the physical area of the intersection. Accordingly, an intersection traffic signal timing method based on the intersection physical zone traffic status (IPAT-ATS) is proposed in this study. Different types of intersection anomalies are defined based on the impact of various abnormal vehicle operating states on vehicle flow in each entrance and exit lane. Using a traffic efficiency model, the flow state of intersections under different abnormal states is analysed to allocate traffic flows optimally, thereby maximising traffic efficiency under various abnormal states. The proposed method undergoes testing through simulations at the Weidi Road and Youyi Road intersection in Tianjin, China. Compared with the current signal timing scheme, this method significantly enhances the intersection efficiency for different traffic anomalies.

Este estudo objetiva analisar a habilidade gerencial na prática do gerenciamento de resultados, via suavização de resultados e accruals, nas empresas da B3. Para tal, realizou-se uma pesquisa quantitativa e descritiva com os dados obtidos na base de dados da Economática, que perfez uma amostra com 966 observações, no período de 2010 a 2020. Utilizou-se como medida de habilidade gerencial o modelo de Demerjian et al. (2012), que possui como parâmetros de eficiência as características do gerente na utilização dos recursos para gerar receitas. Para medir a suavização e os níveis de gerenciamento de resultados, utilizaram-se os modelos de Leuz et al. (2003) e McNichols (2002), respectivamente. Os resultados demonstraram que, em média, os gestores mais habilidosos tendem a suavizar e gerenciar resultados em níveis maiores do que gestores com menor habilidade, o que sinaliza que no Brasil, em média, os gestores mais hábeis tendem a diminuir a qualidade do lucro das firmas brasileiras. Este trabalho contribui com a literatura e preenche uma lacuna sobre a habilidade gerencial e o impacto dos resultados das empresas brasileiras, pois evidencia que, no Brasil, a habilidade gerencial está associada com práticas de suavização e gerenciamento de resultados e lança uma luz para as partes interessadas a respeito da influência do perfil dos gestores e suas capacidades de influenciarem nos números divulgados no mercado brasileiro.
