Authors: Lai Shu-Li
Published: January 2024

The paper presents a study that addresses common issues in the EFL context, specifically the lack of student engagement and limited exposure to the language. The study implemented a flipped classroom approach to enhance learner engagement and improve language learning outcomes. This study involved 32 non-English majors and utilized 6 Minute English Podcasts and TED Talks as core materials, supplemented by blog writing assignments to connect in-class and out-of-class learning. Students engaged with online course materials before attending in-class discussions and worked on their blog assignments after class. Research tools included pre- and post-language proficiency tests, an end-of-semester questionnaire, student blog writings, and their reflection papers.

The results of the Wilcoxon signed-rank test indicated a significant improvement in students' listening skills (z=-4.099, p<0.001). Regarding their performance in speaking and writing, the results of the paired t-tests showed that students demonstrated varying levels of improvement, with the most significant improvements in the writing test (p<0.001) with a large effect size (d=1.94). The findings highlight significant progress in listening, writing, and listen-to-write skills, resulting from the synergistic integration of high-quality online audio and video resources, blog writing assignments, and the flipped teaching approach. This research offers valuable insights for practitioners seeking to enhance language acquisition, particularly within the EFL context.

Authors: Porciuncula Lígia Maria Teixeira Pereira , Cerqueira Pedro Henrique de Jesus , Carvalho Jéssica Moreira Cavalcante
Published: January 2024

Objective: The fat-grafted latissimus dorsi muscle flap has become an excellent option for immediate or late post-mastectomy autologous breast reconstruction. The latissimus dorsi flap without skin island can be used in immediate reconstruction after skin- and nipple-sparing mastectomy, as there is no need to replace the skin on the breast. The work presented here describes a new approach of the Mini flap of the dorsal fat graft in the total breast reconstruction after skin- and nipple-sparing mastectomy in patients with small- and medium-sized breasts, eliminating its classic scar from the removal of the island of skin on the side of the thorax. Methodology: Initially, a skin- and nipple-sparing mastectomy is performed through an incision in the lateral portion of the inframammary fold. Then, through the same incision, the latissimus dorsi muscle is identified. The muscle is sectioned at its insertions and transposed to the mastectomy bed. The inferior, medial, and superior portions (tendon) of the muscle are preserved (mini flap). Liposuction is performed on the abdominal wall and/or thighs, and the fat graft is performed in several planes such as a skin flap from the mastectomy, intramuscular in the pectoralis major and in the latissimus dorsi flap. Results: This new method was performed in five cases. The average duration of the total procedure (mastectomy + axillary approach + reconstruction) was 296 min (270–330), the average breast weight was 350 g (205–458), and the average volume of fat grafted was 234 ml (190–270). We had two cases of seroma in the donor area. Conclusion: The lipo-filled skin-sparing mini dorsi flap allows small- and medium-sized breasts to be completely reconstructed with autologous tissue without scarring on the back, without the need to change position, and without the complete removal of the latissimus dorsi muscle.

Objective: The objective of this study was to analyze magnetic resonance imaging (MRI) BI-RADS® using criteria of high and low suspicion in relation to age group variables and imaging findings. Methodology: This is a cross-sectional retrospective study of analysis of breast MRI exams in an imaging clinic in the city of Goiânia, GO, from 2021 to 2022. The sample was divided according to the BI-RADS® classification into two groups, one with low suspicion for classifications 1, 2, and 3 and another one of high suspicion for classifications 0, 4, 5, and 6. The sample profile of patients with BI-RADS® MR low and high suspicion was tested by applying Pearson’s chi-square test, relative frequency, and absolute frequency, analyzed using the Statistical Package for Social Science (SPSS 26.0) with a significance of 5% (p<0.05). This study was approved by the research ethics committee. Results: A total of 307 exams with indications for MRI were evaluated. Data on the age of patients inferred that the mean was 49.1 years (standard deviation 11.5) and ranged from 24 to 83 years, and 61 (19.9%) were aged ≥60 years. When evaluating the BI-RADS® MRI results with the low and high suspicion criteria, women aged 60 years or older had a significant prevalence (p=0.03) of high suspicion. The concordant findings described in the examination report were breast lump (p<0.01), cyst (p<0.01), nonspecific enhancement (p<0.01), post-surgical alterations (p <0.01), fold of the implant (p=0.04), and inflammatory process (p=0.04), prevailing findings nodule (77%) for high suspicion and cyst (11.5%) for low suspicion. Conclusion: The association of BI-RADS® of high suspicion with age showed that patients aged ≥60 years are more likely to have high-risk lesions; in the exams, the breast lumps presented concordance for high suspicion and the cysts concordance for low suspicion.

Objective: The coronavirus disease 2019 (COVID-19) pandemic brought significant impacts to the healthcare system due to the new demands generated, which in turn hindered the prevalence of breast cancer diagnosis in Brazil. In this context, this study sought to investigate the prevalence of breast cancer tracking and diagnosis between the federation’s regions during 2018 and 2022. Methodology: This is a cross-sectional study using data collected from the Informatics Department of the Unified Health System (DATASUS) on breast cancer diagnosis between January 2018 and December 2022, in the regions of Brazil. The criteria for selection were the number of mammography exams, using the Breast Imaging-Report and Data System (BI-RADS) score, and the number of positive histopathologic exams. The results were analyzed mathematically. Results: In 2020, compared with 2019, considering the number of mammography exams and malignant breast findings, there was a reduction of 39.0% and 26.6%, respectively. In each region, save for the North, there was a higher reduction than observed at the national level. However, in 2021, there was an increase in the rate of mammography exams and malignant breast findings, and in 2022, there was the highest number of mammography exams, histopathologic exams, and breast cancer diagnoses, since 2018, across the entire country. Conclusion: There was a noticeable decrease in the number of mammography exams and histopathologic exams, particularly during 2020, and the highest number of exams and diagnoses, in the last 5 years, in 2022, after the majority of the population was vaccinated and COVID-19 cases decreased. The data show the impairment in the normal course of preventive exams in the country, considering the reduction of trips and referrals to hospitals, in non-urgent cases, given the population’s fear of COVID-19, consequently reducing the frequency of prevention and early breast cancer diagnosis.

Objective: The objective of this study was to know the clinical–epidemiological profile of patients diagnosed with phylloid breast tumor, in the period from December 2006 to January 2023, in a reference oncology clinic in the city of Teresina, PI. Methodology: This is an observational, descriptive, quantitative, and retrospective study carried out through data collection from medical records. We analyzed 982 medical records of female patients with breast cancer. Variables such as age, personal and family history of cancer, presence of pathogenic variants in the panel tested, and pharmacological and surgical interventions were analyzed, tabulated, and analyzed descriptively in Microsoft Excel. The study included all the medical records of patients seen in this period, excluding those who did not have breast cancer or whose records did not provide sufficient information. The study was approved by the Research Ethics Committee, opinion number 30154720.0.0000.5209. Results: Of the patients diagnosed with breast cancer, those with phylloid tumors represented 0.5% of the total, with a mean age of 45 years. Four types of incident diagnoses were found, namely, borderline phylloid tumor (40%), malignant phylloid tumor associated with the heterologous component of liposarcoma (20%), benign phylloid tumor (20%), and phylloid breast tumor (20%). Among the clinical characteristics, the cases that presented a survival of the patients without the disease represented 40% in opposition to the cases of survival with the disease that represented 60%, and the largest tumor size was 11.5 cm. Conclusion: In this study, the cumulative incidence of phylloid breast tumors in women diagnosed with breast cancer in the study population from December 2006 to January 2023 was 0.5%, with the phylloid borderline tumor having the highest prevalence among the cases studied.

Authors: Antonini Marcelo , Morais Isabela Sousa , Salerno Gisela Rosa Franco
Published: January 2024

Objective: The aim of this study was to verify whether the primary care strategies carried out by physiotherapy in the immediate postoperative period of breast cancer are effective. Methodology: This is a retrospective study of consultations carried out in the breast ward by the physiotherapy service, including screening of consultations from February 2019 to February 2023. The data analyzed were age, education, marital status, parity, hormonal status, diagnosis, dominant limb, type of surgery, condition of the scar, need for referral to physiotherapeutic care, and the physiotherapeutic strategies adopted at that time. The study was approved by the Brazil Platform (CAAE 56561222.9.0000.0084). Results: A total of 122 files were analyzed, and 12 (9.8%) were excluded due to missing data; the mean age was 51.66±16.2 years, 31 (28%) had completed high school, 43 (39%) were married, 26 (23%) were nulliparous, and 58 (51%) underwent menopause. As for the diagnosis, 78 (70%) discovered it through self-examination and only 28 (25%) through mammography, 45 (40%) had cancer on the dominant side. Quandrantectomy was the most common surgical type in 40 (36%), followed by sectorectomy in 21 (19%), and lymph node dissection was present in 11 (10%). Inflammatory signs were not identified in 58 (52.7%), and 69 (62.7%) were referred for physiotherapy. All women were instructed to freely maintain upper limb movements and taught to perform simple free active movements at home for the prevention of lymphedema, being reinforced by the delivery of educational material. After a week, it was observed that all of them had no signs of lymphedema and or upper limb movement loss. Conclusion: The performance of physiotherapy in the immediate postoperative period is extremely relevant in caring for the scar/hydration of the skin and in stimulating free active exercise that may prevent the development of lymphedema or even functional limitation due to kinesiophobia. Delivery of educational material, as well as physiotherapeutic follow-up at the time of chemotherapy/radiotherapy, enhances the positive results.

Published: January 2024

Objective: This study aimed to bring epidemiological information about male breast cancer (BC) and also prevention importance to this group. Methodology: For this purpose, data from the Department of Informatics of the Unified Health System (DATA-SUS) were used, in which cases were investigated by gender according to the year of diagnosis of BC in Brazil, between the years 2013 and 2022. Results: BC is the second most prevalent cancer in the world. In Brazil, BC will represent, according to the National Cancer Institute, it is estimated that, between 2023 and 2025, 10.2% of all types of cancer in the country. Furthermore, it is common knowledge that BC also affects the male population, representing 1% of cases; however, its incidence has increased significantly throughout the world, including in our country in the last decade. Thus, there was a significant increase in the analyzed data during this period of time, in which, respectively, we had between 2013 and 2022, 229, 267, 255, 274, 268, 482, 1,021, 1,059, 1,493, and 848 cases of male BC. Moreover, when analyzing BC screening and combat campaigns in Brazil, it appears that they, for the most part, dialogue only with women, leaving an illusion that men should not be concerned with this category of cancer. In addition, studies reveal that male BC patients had worse survival outcomes compared with female patients. Conclusion: Therefore, we conclude that public policies and emphatic and educational campaigns are necessary, which explain the reality of male BC, with the intention of informing its risks, in an attempt to increase screening, thus reducing the incidence and mortality of BC in men.
Metabolic syndrome as a risk factor for the development of breast cancer in women and its impact on prognosis
Authors: Ribeiro Laíse Alves , Camargo João Victor Monteiro de , Joioso Bruno Buzá , Joioso Ailton
Published: January 2024

Objective: Metabolic syndrome (MS) is a complex metabolic disorder. The aforementioned main components are systemic arterial hypertension, insulin resistance, obesity, and dyslipidemia. Highly acclaimed evidence supports the hypothesis that MS may be associated with breast cancer (BC) development and worse prognosis. The increasing incidence rates of both MS and BC seem to corroborate this theory. This article aims to assess the association between MS and BC development, later diagnosis, and worse prognosis. Methodology: An inclusive literature review was conducted on PubMed and SciELO. Results: First, excess of adipose tissue characteristic of MS not only enhances the expression of pro-inflammatory factors but also increases the aromatization process. The latter is a neuroendocrine change that occurs in adipocytes and leads to greater estrogen synthesis, which increases the risk for the development of BC. It was concluded that MS is an independent risk factor for BC with a relative risk (RR) of 1.75%. MS is also associated with more aggressive and poorer differentiated tumors. Women with MS have higher rates of BC in stages III and IV. Furthermore, hyperinsulinemia and hyperglycemia are directly related to axillary lymph node involvement, high histological grade, and late staging. Moreover, it is known that women diagnosed with both MS and BC have worse oncologic prognosis. The aforesaid is exemplified by the increased recurrences and decreased survival in BC associated with high fasting plasma insulin levels. Additionally, obese women with BC have a worse prognosis and a higher risk of developing a second primary BC. Conclusion: As mentioned above, MS is significantly associated with an increased risk, invasive progression, and adverse outcomes of BC due to neuroendocrine changes, namely, abnormal estrogen levels. It is therefore strongly recommended to adhere to dietary strategies and regular physical activities in order to prevent MS. Consequently, there would be a possibility of reducing the incidence rates of BC.

Published: January 2024

Most of the study of robots is about the system. Because of that, we analyze the motion of the robot by using rigid body motion concepts. This study aims to analyze the rotation components of a robotic manipulator with four degrees of freedom (4-DoF) by using the quaternion method of manual analysis so that the end effector of the robotic manipulator under study is obtained. The research is theoretical and was conducted through a review and analysis of related literature. Based on the literature review, the robotic manipulator is a robot with a shape resembling an arm. The robotic manipulator consists of bases, links, joins, and an end effector. In terms of physics, the kinematics of robot motion can be studied based on the concept of rigid body motion. The research shows that the quaternion method can be used to determine the end effector of the rotation component of the robotic manipulator, and the steps are shorter than analyses by using screw and twist theory. Based on this case, the end effector of the rotation component depends on the initial state and the total rotation angle of each join.

MAGNITUDE E TENDÊNCIA DA MORTALIDADE MATERNA NO ESTADO DO MARANHÃO E SUAS REGIÕES DE SAÚDE NO PERÍODO DE 2009 A 2015
Authors:   , SILVA MACLEYA GOMES
Published: January 2024

Objetivos: Comparar as razões de morte materna (RMM) calculadas por dois métodos para o Maranhão e suas regiões de saúde (2009 a 2015) e analisar a tendência. Métodos: A RMM foi calculada pelo método direto (RMM SIM) e método corrigido (RMM corrigida). A comparação foi realizada pelo teste T de Student pareado e a análise de tendência pela regressão Prais-Winsten. Resultados: A RMM SIM média no estado foi de 89.63 e a RMM direta 114.01. Foi observada diferença significativa entre a RMM SIM e RMM corrigida em todas as regiões. Houve tendência crescente da RMM corrigida em Imperatriz (b=0.04; P=0.042), Presidente Dutra (b=0.06; P=0.014) e Zé Doca (b=0.09; P=0.016). Nas demais regiões houve tendências decrescentes ou estacionárias. Conclusão: No Maranhão e regiões de saúde a RMM corrigida é o indicador mais fidedigno. Deve ser dada atenção à saúde materna nas regiões que apresentaram tendência crescente e/ou valores altos.

A geografia amazônica em múltiplas escalas Volume 3
Authors: Aleixo Natacha Cíntia Regina
Published: January 2024

A Amazônia, pela grandiosidade territorial e pela complexidade dos elementos que a compõe, associado ao pouco incentivo à pesquisa científica, ainda continua sendo um grande desafio para as ciências e outros tipos de conhecimentos. A situação se torna mais preocupante quando se observa que a velocidade da destruição dos sistemas naturais e os impactos para os povos originários são muito mais rápidos do que os avanços dos conhecimentos científicos. Com isso sabe-se que muitas espécies da flora e fauna estão sendo dizimadas antes mesmos de serem conhecidas pela ciência. O mesmo pode-se dizer em relação aos povos originários em que muitas das nações foram extintas sem ou com poucas informações dos mesmos.
Mais recentemente a expansão dos cursos de pós-graduação nas instituições de ensino superior do Norte do Brasil passaram a contribuir de forma mais efetiva na produção de conhecimentos da Amazônia brasileira através de teses e dissertações. Neste contexto está inserida a Universidade Federal do Amazonas – UFAM, e nela o Programa de Pós-Graduação em Geografia (PPGEOG/UFAM) com os cursos de mestrado e mais recentemente o doutorado, onde muito dos resultados das pesquisas desse Programa estão sendo disponibilizada ao público em geral através de publicações como a coletânea A Geografia amazônica em múltiplas escalas.
O terceiro volume dessa coletânea é composto por 12 capítulos, resultado das pesquisas dos mestrandos e doutorandos e seus respectivos orientadores das duas linhas de pesquisa do Programa: Amazônia Território e ambiente e Domínio da natureza na Amazônia. São capítulos, como já contido no título, de visões multidimensionais e interdisciplinares como pensa Edgar Morin sobre a Geografia em A Cabeça bem feita (2003, p. 28 e 29). A organização deste volume coube aos professores doutores Natacha Cíntia Regina Aleixo, Raphael Fernando Diniz e Antonio Fábio Sabbá Guimarães Vieira.
ANÁLISE DAS MUDANÇAS NA COBERTURA DO SOLO E NA PRECIPITAÇÃO NA BACIA DOS RIOS BENI E MAMORÉ

A Bacia do rio Madeira, situada no sudoeste da Amazônia brasileira, é uma região de grande importância ecológica. Com uma área aproximada de 1,4 milhão de quilômetros quadrados (MUNIZ; FILIZOLA, 2015), abrange uma diversidade de ecossistemas, desde florestas tropicais úmidas até savanas. O rio Madeira é um dos principais afluentes do rio Amazonas, e em termos de vazão está entre os 10 maiores rios do mundo (LATRUBESSE et al., 2005)b. Seu curso fluvial é bastante navegável e contribui para o escoamento da produção principalmente de grãos de soja e milho da região centro-oeste a norte do território brasileiro (GOMES et al., 2019).
Na Amazônia, os rios desempenham um papel fundamental, indo além do abastecimento para consumo ou irrigação. Possui um sentido vinculado às atividades comerciais além de ser um delimitador natural de fronteiras (NOGUEIRA; OLIVEIRA NETO, 2022). O uso do canal fluvial como meio de transporte e conexão entre os municípios da região é comum, com diferentes tempos de deslocamentos em função do período do ano. Essas variações ocorrem devido às características hidrológicas distintas presentes na bacia Amazônica (FILIZOLA et al., 2002).
CARTOGRAFIA INCLUSIVA: A PRODUÇÃO DE MAPAS TÁTEIS NO ENSINO DE GEOGRAFIA ESCOLAR, MANAUS-AM

A orientação espacial é a capacidade de uma pessoa de perceber o ambiente, estabelecendo relações corporais, espaciais e temporais com ele. A orientação não se limita a estabelecer uma posição no espaço, mas vai muito além da mobilidade independente, onde se tem a ideia de saber onde se situa, mas também a capacidade de identificar lugares, possíveis direções a objetivos desejados e poder tomar decisões com autonomia.
A cartografia tátil é uma área específica da Cartografia, que se dedica à confecção de mapas e outros produtos cartográficos que possam ser lidos por pessoas cegas ou com baixa visão. Assim, os mapas táteis, os principais produtos da cartografia tátil, são representações gráficas em textura e relevo, destinadas à orientação e localização de lugares e objetos para as pessoas com deficiência visual. Os mapas táteis também são utilizados para a disseminação de informações espaciais, ou seja, para o ensino de Geografia e História, permitindo que pessoas com deficiência visual ampliem sua percepção do mundo. Dessa forma, são um recurso valioso para a inclusão social (LOCH, 2008).
REFLEXÕES ANTICOLONIAIS PARA UMA GEOPOLÍTICA DOS POVOS AMAZÔNICOS
Authors: Vilagelim Guilherme , Faria Ivani Ferreira de
Published: January 2024

Mergulhar na decolonialidade significa procurar entender por que devemos nos preocupar com os povos amazônicos, o equilíbrio do bioma e dos ecossistemas que o compõem. É o caminho para começar a olhar com responsabilidade sobre o que estamos fazendo com os elementos naturais e com os povos e comunidades que sobrevivem nesse território e nessa terra. Questionamo-nos qual caminho queremos trilhar e para onde essa lógica de produção está nos levando e como podemos contribuir para a promoção da paz, da justiça social e do bem viver da coletividade nesses territórios.
A opção em realizar essas reflexões geopolíticas traz à tona as mais variadas formas de se pensar o território, elucidando as relações de poder e as suas dinâmicas territoriais que são, constantemente, transformadas pelos sujeitos sociais, resgatando, assim, a geografia política enquanto componente essencial no processo histórico de formação das sociedades, que contribui ao analisar o poder, o território e a política de maneira multicausal, multiescalar e, aqui em específico, anticolonial.
Isso se faz necessário para mostrar caminhos que possibilitem desconstruir a histórica relação de desapropriação, exploração e dependência causada pelas atividades extrativistas coloniais, como, por exemplo, a mineração, que historicamente vem acontecendo de maneira cíclica, deixando danos quase que irreparáveis aos povos e ao bioma amazônico.
