Environmentally sustainable: How are the practices in the organic food tourist route?

This study analyzes Environmentally Sustainable Practices (ESPs) in the Organic Food Tourist Route (OFTR) in South Brazil. Data collection included interviews with open and closed questions about ESPs and the Barometer of Tourism Sustainability (BTS) tool. Eight owners or managers of OFTR's enterprises answered questions online or personally. Content analysis and descriptive statistics were used. Results indicated that tourism enterprises adopt ESPs according to each reality since some are dedicated to producing and commercializing organic products, while others are dedicated to lodging and guided tours. Managers realize the importance of adopting ESPs, enabling a decrease in expenses and the supply of organic products. Since tourists are concerned and careful with the environment nowadays, sustainability must be considered, becoming a differential. The enterprises develop ESPs, which makes the route potentially sustainable, following the standards established by the BTS. In order to achieve the "sustainable" level, the enterprises on the route need to improve their performance in many items whose results were less sustainable. From a theoretical perspective, this study contributed to understanding how ESPs were developed in enterprises and how they contribute to tourism development. The understanding of tourist routes expanded with an emphasis on sustainability, the environmental dimension, the ESPs, and organic agriculture. The BTS enabled the assessment of the sustainability of OFTR's enterprises.

EPHA2-dependent outcompetition of KRASG12D mutant cells by wild-type neighbors in the adult pancreas.

As we age, our tissues are repeatedly challenged by mutational insult, yet cancer occurrence is a relatively rare event. Cells carrying cancer-causing genetic mutations compete with normal neighbors for space and survival in tissues. However, the mechanisms underlying mutant-normal competition in adult tissues and the relevance of this process to cancer remain incompletely understood. Here, we investigate how the adult pancreas maintains tissue health in vivo following sporadic expression of oncogenic Kras (KrasG12D), the key driver mutation in human pancreatic cancer. We find that when present in tissues in low numbers, KrasG12D mutant cells are outcompeted and cleared from exocrine and endocrine compartments in vivo. Using quantitative 3D tissue imaging, we show that before being cleared, KrasG12D cells lose cell volume, pack into round clusters, and E-cadherin-based cell-cell adhesions decrease at boundaries with normal neighbors. We identify EphA2 receptor as an essential signal in the clearance of KrasG12D cells from exocrine and endocrine tissues in vivo. In the absence of functional EphA2, KrasG12D cells do not alter cell volume or shape, E-cadherin-based cell-cell adhesions increase and KrasG12D cells are retained in tissues. The retention of KRasG12D cells leads to the early appearance of premalignant pancreatic intraepithelial neoplasia (PanINs) in tissues. Our data show that adult pancreas tissues remodel to clear KrasG12D cells and maintain tissue health. This study provides evidence to support a conserved functional role of EphA2 in Ras-driven cell competition in epithelial tissues and suggests that EphA2 is a novel tumor suppressor in pancreatic cancer.

Targeting the Intrinsic Apoptosis Pathway: A Window of Opportunity for Prostate Cancer.

Despite major improvements in the management of advanced prostate cancer over the last 20 years, the disease remains invariably fatal, and new effective therapies are required. The development of novel hormonal agents and taxane chemotherapy has improved outcomes, although primary and acquired resistance remains problematic. Inducing cancer cell death via apoptosis has long been an attractive goal in the treatment of cancer. Apoptosis, a form of regulated cell death, is a highly controlled process, split into two main pathways (intrinsic and extrinsic), and is stimulated by a multitude of factors, including cellular and genotoxic stress. Numerous therapeutic strategies targeting the intrinsic apoptosis pathway are in clinical development, and BH3 mimetics have shown promising efficacy for hematological malignancies. Utilizing these agents for solid malignancies has proved more challenging, though efforts are ongoing. Molecular characterization and the development of predictive biomarkers is likely to be critical for patient selection, by identifying tumors with a vulnerability in the intrinsic apoptosis pathway. This review provides an up-to-date overview of cell death and apoptosis, specifically focusing on the intrinsic pathway. It summarizes the latest approaches for targeting the intrinsic apoptosis pathway with BH3 mimetics and discusses how these strategies may be leveraged to treat prostate cancer.

Orofacial trauma and mouthguard use in Brazilian rugby union players.

BACKGROUND/AIM: Rugby union represents a high-risk sport for orofacial trauma due to its impact collisions and repetitive tackles. The aim of this study was to investigate the prevalence of orofacial trauma according to mouthguard use among a sample of Brazilian rugby union players. METHODS: An online questionnaire was sent to the 16 best rugby union clubs in Brazil. The questionnaire contained questions about the training history of each athlete, prevalence of orofacial trauma, and details about mouthguard use. Only participants who reported using a mouthguard were selected for this analysis. RESULTS: A total of 244 individuals were included. The prevalence of orofacial trauma was 34.4%, and 61.9% of them did not wear a mouthguard at the time of the incident. The only type of mouthguard reported was the pre-fabricated ("boil and bite" and "ready-to-wear") type. A stronger association was observed between the reason for using a mouthguard and the outcome, whereas a lower proportion of trauma was observed among individuals who claimed mandatory mouthguard use at the gym/sport (20.0%). Time since the respondent started playing rugby union and who instructed them to use a mouthguard were not associated with orofacial trauma. CONCLUSION: Prevalence of orofacial trauma was high among this sample of rugby union players from Brazil, even with the use of pre-fabricated mouthguards. This study encourages further investigation on the use of custom-made mouthguards in rugby union and the role of coach/physical educators to reduce the prevalence of orofacial trauma.

Determinants for traumatic orofacial injuries in sport: Extrinsic factors in a scoping review.

BACKGROUND/AIM: Sports practices carry a risk for orofacial injuries and, to avoid them, preventive measures are necessary. The aim of this study was to investigate a web of extrinsic determinants for orofacial trauma in sports. MATERIALS AND METHODS: Through a scoping review, eight extrinsic risk factors for sports-related orofacial trauma emerged from the thematic analysis. These were sports modality, sports philosophy, competition rules, level of competition, accessory equipment, environmental conditions, acting regimen, pitch conditions, and human resources. The data collection was conducted on seven databases, using terms based on health science descriptors and keywords related to orofacial trauma and sports. RESULTS: From the 1155 articles found, 157 were selected based on eligibility criteria and classified according to the mentioned factors. After the full reading of the articles, the most cited risk factor was sports modality while acting regimen and environmental factors were the least mentioned. Therefore, a scheme following the web of determinants was constructed with the purpose of establishing a risk profile, which was based on the interactions between the determinants and on the frequency that they were mentioned as contributors to injury. From this, it was observed that each traumatic event is possibly a result of the interrelationships among the eight suggested determinants. CONCLUSION: Sports modality was the most cited extrinsic determinant observed in the literature, while environmental conditions and acting regimen were the least cited. In addition, more than establishing the determinants, it is necessary to comprehend how they relate, once preventive strategies should intercede on these relations, to help reduce sports injuries.

Sociabilidade e lazer entre mulheres camponesas: vivências no clube de mães / Sociability and leisure among peasant women: experiences in the mothers club

O estudo realiza uma análise de uma organização denominada clube de mães. A partir de um estudo de caso, na comunidade São Caetano, município de São Lourenço do Oeste, em Santa Catarina/Brasil, nosso objetivo foi compreender o papel que o clube de mães ocupa nas práticas de sociabilidade e nas formas de organização de mulheres camponesas. O clube de mães transpõe as dicotomias dos espaços sociais, abrindo a possibilidade de ação das mulheres no espaço público, já que elas passam a frequentar outras comunidades, e deslocam-se a outros municípios, para os quais viajam coletivamente. Ao observar o significado do clube de mães, compreende-se o aumento do reconhecimento e da visibilidade das mulheres camponesas, além da constituição deafeto entre elas.

The study conducts an analysis of an organization called the Mothers Club from a case study in the São Caetano community, municipality of São Lourenço do Oeste, in Santa Catarina / Brazil, our The objective was to understand what role the mother club plays in sociability practices and forms of women's organization peasants. The mothers club bridges the space dichotomies opening up women's action in the space as they come to attend other communities, and they travel to other municipalities, to which they travel collectively. Observing the meaning of the mothers club means increasing the recognition and visibility of peasant women, as well as the constitution of affection between them.

Prevalence of dentofacial injuries among combat sports practitioners: A systematic review and meta-analysis.

BACKGROUND/AIM: Combat sports might result in injuries to the face and teeth. However, it is unclear how often they occur and which sports presents the highest rates. The aim of this study was to investigate the prevalence of dentofacial injuries in combat sports participants. MATERIAL AND METHODS: A systematic review was performed. Six main electronic databases and three grey literature databases were searched. Studies were blindly selected by two reviewers based on pre-defined eligibility criteria. Studies that evaluated the prevalence of dentofacial injuries (teeth, alveolar bone, jaw, lips, and/or cheekbones) among combat sports participants were considered eligible. Risk of bias was assessed using the Joanna Briggs Institute Critical Appraisal Checklist. The software r statistics version was used to perform all meta-analyses. Cumulative evidence of the included articles was evaluated using GRADE criteria (Grading of Recommendations Assessment, Development and Evaluation). RESULTS: From 1104 articles found on all databases, 27 were finally included. Eighteen studies were judged at low, seven at moderate, and two at high risk of bias. The following sports were investigated: boxing, capoeira, fencing, jiu-jitsu, judo, karate, kendo, kickboxing, kung fu, muay thai, sumo, taekwondo, wrestling, and wushu. Results from the meta-analysis suggested a dental pooled prevalence of 25.2% (12.3%-40.8%, i2  = 100%) and dentofacial pooled prevalence of 30.3 (18.1%-44.1%, i2  = 100%). Considering the sports' categories individually, jiu-jitsu had the highest pooled prevalence of dentofacial injuries (52.9% [37.9%-67.8%, i2  = 92%]), while judo was the sport with the lowest pooled prevalence (25.0% [7.6%-48.2%, i2  = 98%]). Among Panamerican sports, boxing had the highest prevalence of dental injuries (73.7% [58.7%-86.3%, i2  = 0%]). For dentofacial injuries, the GRADE criteria were considered low. CONCLUSIONS: Overall pooled prevalence of dentofacial injuries in combat sports was approximately 30%. Raising awareness regarding the frequency of these injuries might encourage the use of protective devices and reduce complications related to these incidents.

Effect of relining on the misfit of microwavecured acrylic resin denture bases / Efeito do reembasamento na desadaptação de bases de próteses de resina acrílica polimerizada por micro-ondas

Objective: The aim of this study was to evaluate the effect of microwave-energy polymerization on the accuracy and glass transition temperature of acrylic resin denture bases submitted to reline procedure. As denture wearers make up a large portion of the population and often cannot afford a new complete denture, the reline procedure may be the best alternative when indicated. Thus, it is important to evaluate possible changes that would contraindicate this technique. Materials and methods: Twenty denture bases were fabricated from microwave-cured acrylic resin (Onda-Cryl) and randomly divided into control and test groups (n = 10). In the control group, the bases were submitted to measurement of misfit. Bases in the test group were worn down internally and relined. Misfit was measured by cutting the set stone cast/denture base at three predetermined points (canine, molar and tuberosity), measuring the gap between the stone cast and the acrylic resin base at three points using the ImageTool®software suite. Differential scanning calorimetry was used to determine Tg. Data were submitted to t-test for independent- samples (p<0.05). Results: The greatest misfit of canine sections was found at the midpoint of control group (0.280 mm); in molar sections, no significant difference was found. In maxillary tuberosity sections, the greatest misfit occurred at the midpoint of test group (0.352 mm). All gaps were below the maximal clinically acceptable misfit value. There was no significant difference in Tg values between groups. Conclusion: Microwave-energy processing does not affect the fit or Tg of relined denture bases.

Objetivo: Avaliar o efeito da polimerização utilizando energia de micro-ondas na adaptação e na temperatura de transição vítrea de bases de prótese submetidas ao procedimento de reembasamento. Uma vez que usuários de próteses totais constituem grande parte da população, o procedimento de reembasamento pode ser a melhor alternativa, quando indicado. Assim, se faz importante a avaliação de possíveis alterações que contraindicariam esta técnica. Materiais e Métodos: Foram confeccionadas 20 bases de prótese utilizando resina acrílica polimerizada por micro-ondas (Onda-Cryl) e divididas aleatoriamente em grupo controle e teste (n=10). No grupo controle as bases foram submetidas à mensuração da desadaptação. Já no grupo teste as bases foram desgastadas internamente e submetidas ao procedimento de reembasamento utilizando a mesma resina acrílica e a polimerização por energia de micro-ondas. A desadaptação foi mensurada por meio do corte do conjunto modelo de gesso/ base de prótese, em três pontos pré-determinados, em ambos os grupos. Cada área seccionada foi mensurada em três pontos, utilizando o programa ImageTool®software. O ensaio de calorimetria exploratória diferencial foi utilizado para determinar a Tg em ambos os grupos. Os dados foram submetidos ao teste t para amostras independentes (p<0,05). Resultados: No bloco de canino, a maior desadaptação foi observada no ponto mediano do grupo controle (0,280 mm); no bloco de molares não houve diferença estatística entre os grupos. Já na comparação dos blocos de tuber, a maior desadaptação ocorreu no ponto mediano do grupo teste (0,352 mm). Apesar dos valores de desadaptação encontrados, nenhum foi igual ou superior ao valor máximo aceito clinicamente. Conclusão: A polimerização utilizando energia de micro-ondas não afetou a adaptação ou a Tg das bases de prótese submetidas ao reembasamento.

Sustained effect of bone marrow mononuclear cell therapy in axonal regeneration in a model of optic nerve crush.

In adult mammals, the regeneration of the optic nerve is very limited and at the moment there are several groups trying different approaches to increase retinal ganglion cell (RGC) survival and axonal outgrowth. One promising approach is cell therapy. In previous work, we performed intravitreal transplantation of bone-marrow mononuclear cells (BMMCs) after optic nerve crush in adult rats and we demonstrated an increase in RGC survival and axon outgrowth 14 days after injury. In the present work, we investigated if these results could be sustained for a longer period of time. Optic nerve crush was performed in Lister-hooded adult rats and BMMC or saline injections were performed shortly after injury. Neuronal survival and regeneration were evaluated in rats׳ retina and optic nerve after 28 days. We demonstrated an increase of 5.2 fold in the axon outgrowth 28 days after lesion, but the BMMCs had no effect on RGC survival. In an attempt to prolong RGC survival, we established a new protocol with two BMMC injections, the second one 7 days after the injury. Untreated animals received two injections of saline. We observed that although the axonal outgrowth was still increased after the second BMMC injection, the RGC survival was not significantly different from untreated animals. These results demonstrate that BMMCs transplantation promotes neuroregeneration at least until 28 days after injury. However, the effects on RGC survival previously observed by us at 14 days were not sustained at 28 days and could not be prolonged with a second dose of BMMC.

Fatores relevantes para a mudança na formação em Odontologia motivados pelo Programa Nacional de Reorientação da Formação Profissional em Saúde (Pró-Saúde) / Relevant factors for change in Dentistry training motivated by the National Program for the Reorientation of Healthcare Training (Pró-Saúde)

Este trabalho, de natureza exploratória, visa a reunir informações sobre os projetos participantes do Programa Nacional de Reorientação da Formação Profissional em Saúde ­ Pró-Saúde, na área de Odontologia. O estudo fundamenta-se nos pressupostos de gestão do conhecimento e da educação em saúde e objetiva analisar fatores relevantes para mudança na formação em Odontologia, através da aplicação da ferramenta de mineração de textos. Traz subsídios à avaliação do caminho das mudanças vivenciadas no âmbito das Instituições de Ensino Superior e dos serviços de saúde advindas com a implementação das Diretrizes Curriculares Nacionais e do Programa Pró-Saúde. A coleção textual analisada é composta por 20 relatórios parciais (80% do universo) referentes aos dois anos de vigência do Programa. Três categorias são analisadas utilizando técnicas de descoberta do conhecimento: relação ensino-serviço, características organizacionais e filosofia pedagógica. Considerando os eixos de avaliação propostos pelo Pró-Saúde, o eixo B, Cenários de Prática, parece ser o fator que mais contribui no desenvolvimento dos projetos, em especial o vetor B1, integração ensino-serviço, que se mostra como grande impulsionador da mudança na formação em nível de Graduação em Odontologia em direção ao Sistema Único de Saúde. A descoberta do conhecimento e suas ferramentas de análise mostram-se importantes para aplicação em futuros trabalhos acadêmicos na área da saúde, em especial na Odontologia (AU).

This exploratory work aimed to gather information on the projects participating in the National Program for the Reorientation of Healthcare Training, in the area of Dentistry. The study is based on the assumptions of knowledge management and health education and aims to examine relevant factors for change in dentistry training, through the application of text mining tools. The study provides subsidies to evaluate the path of the changes experienced within the Institutions of Higher Education and health services resulting from the implementation of the National Curriculum Guidelines and Pró-Saúde. The textual collection under analysis consists of twenty partial reports (80% of the universe), concerning the two years duration of the program. Three categories are analyzed using knowledge discovery techniques: education and service relation, educational philosophy, and organizational characteristics. Considering the axes of assessment proposed by the program Pró-Saúde, the axis B, Practice Scenarios, seems to be the prime factor in the development of projects, in particular the vector B1, the integration between education and the public health service, which constitutes the main factor for change in higher education in Dentistry towards the Unified Health System. Knowledge discovery and its tools proved important for future academic studies in the area of health, especially in Dentistry (AU).

Percepção dos formandos do Centro de Ciências da Saúde da Universidade Federal de Santa Catarina sobre o que é promoção da saúde / The perception of senior students from the Health Science Center at the Federal University of Santa Catarina regarding health promotion

Como resposta aos desafios sanitários contemporâneos, a Promoção da Saúde delineia-se num campo teórico-prático-político envolvendo ações e projetos em saúde, apresentando-se em todos os níveis de complexidade da gestão e atenção do sistema de saúde. Para tanto, deve incluir capacitação da comunidade para que a mesma, visando melhoria de qualidade de vida e saúde, possa atuar juntamente no controle desse processo. Dada a importância desse conhecimento, o presente trabalho propô-se identificar a percepção dos formandos do Centro de Ciências da Saúde (CCS) da Universidade Federal de Santa Catarina (UFSC) sobre o que é Promoção da Saúde. Metodologia: uma pesquisa de campo com caráter descritivo e qualitativo visando analisar a realidade a partir da observação de fenômenos e causas. Os sujeitos da pesquisa foram compostos por formandos dos cursos do CCS da UFSC, sendo 3 representantes de cada curso, em função da saturação de respostas, totalizando 15. As informações pessoais foram submetidas a uma análise descritiva, bem como qualitativa através do processo de Análise-Reflexão-Síntese. Resultados: O perfil da amostra foi predominantemente feminino (60%), com aproximadamente 21 anos de idade. Quanto ao conhecimento sobre a Promoção da Saúde, observou-se dificuldade em conceituar seu significado, sendo que para a maioria da amostra não foi possível diferenciar prevenção de promoção da saúde, além da incapacidade de exemplificar como aplicar em sua prática profissional. Apesar da importância da Promoção da Saúde ter sido reconhecida e exaltada, pôde-se observar falta de conhecimento e entendimento sobre o tema (AU).

In response to the current health challenges, Health Promotion deals with a theoretical-practicalpolitical approach, involves actions and health projects, and underlies all levels of complexity of health system management and of healthcare service provision. It must prepare the community to be able to help in supervising the whole process to improve the quality of life and health. Given the importance of this knowledge, this paper intends to show how senior students from the Health Science Center at the Federal University of Santa Catarina (HSC-FUSC) perceive Health Promotion. Methodology: Field research in the form of a descriptive and qualitative survey, aiming at analyzing the real situation by observing different phenomena and their causes. The survey respondents consisted of senior undergraduate students from HSC-FUSC, specifically, 3 students from each course, resulting in 15 students. The personal information was submitted to a descriptive analysis, as well as to qualitative analysis using the process of Analysis-Reflection-Synthesis. Results: The profile of the surveyed respondents was predominantly female (60%), and the average age was 21 years old. In respect to the students' knowledge of Health Promotion, they demonstrated difficulty in grasping its meaning; most of the respondents could not distinguish health prevention from health promotion, and were also unable to exemplify how they would apply it in their professional practice. Although the importance of Health Promotion is indeed recognized and valued, a lack of understanding and knowledge of this subject prevailed (AU).

Formação em odontologia e interdisciplinaridade: o Pró-Saúde da UFSC / Interdisciplinarity and dentistry training: UFSC's Pro-Health program

Na última década, a formação de profissionais de saúde tem sido reformulada com políticas de educação e de saúde promovidas pelos Ministérios da Educação e Cultura e da Saúde. Este artigo apresenta a experiência do Curso de Graduação em Odontologia da Universidade Federal de Santa Catarina (UFSC) na implantação do Programa Nacional de Reorientação da Formação Profissional em Saúde ­ Pró-Saúde. Como processo indutor, o programa direcionou as mudanças com vistas à integração ensino-serviço e à utilização de novas metodologias de ensino-aprendizagem, enfatizando a atenção básica. Na área de Odontologia, tais movimentos mostram-se necessários tendo em vista que, historicamente, tanto o sistema formador como o mercado de trabalho foram regidos pela iniciativa privada. Na UFSC, as atividades foram estruturadas em conformidade com os três eixos de desenvolvimento do Programa e impulsionaram o movimento de reforma curricular. O Pró-Saúde foi fundamental para a indução desse processo de mudança em uma perspectiva interdisciplinar, trazendo contribuições em todos os eixos (AU).

In the last decade, the training of health professionals was restructured with education and health policies promoted in partnership by the Ministries of Education and Culture and Health. This article presents the experience of the Undergraduate Dentistry Course of the Federal University of Santa Catarina (UFSC) gained in implementing the National Redirection of Vocational Training in Health - Pro-Health. As an inductive process, it led to changes, aiming at integrating learning and health service and at using new methods of teaching and learning, emphasizing primary care. In the field of dentistry, these movements seemed necessary, considering that, historically, both the educational system and the labor market were governed by private initiative. In UFSC, the activities were structured in accordance with the three axes of development presented by the program, and drove the movement to reform the curriculum. Pro-Health was essential for inducing the process of change in an interdisciplinary perspective, offering contributions across all axes (AU).

Effect of radiotherapy on the radiopacity and flexural strength of a composite resin.

The aim of this study was to evaluate the effect of radiotherapy on the radiopacity and flexural strength of composite resin. Forty Z250 composite resin specimens were polymerized using a halogen light-curing unit and divided into 5 groups, in accordance with the radiotherapy dose: G1- without irradiation, G2- 30 Gy, G3- 40 Gy, G4- 50 Gy and GS- 60 Gy Digital images were obtained using a GE 100 X-ray. Radiopacity values were obtained with the Digora digital imaging system and the flexural strength was evaluated with an EMIC universal testing machine. Data were submitted to ANOVA and Tukey 's test. G1 presented the highest radiopacity value, followed by G3, G5, G4 and G2. For flexural strength, G1 presented the lowest value, followed by G2, G5, G3 and G4. Differences were no significant (p>0.05). The commonly used dosage of radiotherapy treatment, did not cause alteration in the radiopacity and flexural strength of resin-based composites.
