First reports of computed tomographic colonography for the screening of colorectal polyps in acromegalic patients

*Aim:* To analyze the CTC performance for the screening of colorectal polyps in acromegalic patients. 

*Materials and Methods:* A prospective study of 21 acromegalic patients, 12 male and 9 female, average age 49, who underwent CTC and CC. CTC was performed with a GE Helical Multislice Computed Tomography Apparatus. The colonoscopy was performed, in the same day, without previous knowledge of the CTC diagnostics. The study evaluated the capacity of CTC to detect patients with colorectal polyps and identify each colorectal lesion described by CC. 

*Results:* In two patients (2/21), CC was incomplete. However, in all patients CTC was complete. In Phase I (“Per Patient”), CTC diagnosed 8 of the 9 patients with colorectal polyps and showed 88% sensitivity, 75% specificity and 81% accuracy. In Phase II (“Per Polyp”), out of the 21 acromegalic patients included in this study, 12 presented normal findings at CC. A total of 19 polyps were identified in 9 patients. 10 of the 19 polyps were smaller than 10 mm, and 9 were equal to or larger than 10. CTC identified 7 of the 9 polyps ≥ 10 mm described by CC and only 6 of the 10 small polyps identified at CC were detected by CTC. The histological analysis of resected lesions revealed 12 tubular adenomas, 6 hyperplastic polyps and 1 colonic tubulo-villous adenoma with an adenocarcinoma focus. 

*Conclusion:* In this study, CTC was performed without complications and a complete and safe colorectal evaluation was possible in all acromegalic patients. Moreover, CTC showed good sensitivity to identify acromegalic patients with colorectal polyps

Tribal Marketing: portuguese adaptation and preliminary psychometric results of tribalism, team brand loyalty, team brand value and personal/group identity questionnaire

O objetivo deste estudo foi adaptar para a população portuguesa e validar as características psicométricas preliminares do questionário de Tribalismo de Rudi Meir, Lealdade Marca-Equipa, Valor Marca e Identidade pessoal/grupo. Foi seguido um protocolo de investigação quantitativo. A recolha de dados foi realizada através de um inquérito com uma amostra selecionada por conveniência composta por n=734 participantes distribuídos por 13 níveis de formação académica. Foi realizada uma análise fatorial confirmatória, no contexto dos modelos de equações estruturais. Os resultados obtidos na amostra portuguesa permitem suportar a estrutura fatorial do Questionário original, “Tribalism, team brand loyalty, team brand value and personal/group identity ”, proposto por Rudi Meir (2009). A versão portuguesa do questionario apresenta propriedades psicométricas satisfatórias quanto à validade e fidelidade representando uma opção valida para a mensuração da fenomenología em causa

Determining Priority and Sustainable Strategies in Agribusiness Management using an Analytic Hierarchy Process model

Publisher Copyright: © 2023, ANPAD - Associacao Nacional de Pos-Graduacao e Pesquisa em Administracao. All rights reserved.The aim of this study was to analyze which business sustainability factors are adopted in the strategic process of the agricultural sector using the model named Strategic Planning for Business Sustainability (PEPSE). To achieve the proposed aim, the PEPSE model was applied to the Analytic Hierarchy Process multicriteria decision tool. During the research, the farm adopted sanitary measures due to the COVID-19 pandemic, which compromised access to managers and, consequently, data collection. Based on the application of a model developed especially for the identification and formulation of sustainable strategies, the study identified how sustainability is considered in the strategic planning of an agricultural unit in Brazil and the strategies adopted to deal with environmental variables. It was possible to understand how the stakeholders influence the planning of the farm and the variables and priority strategies for the environmental positioning of the farm. Thus, the main limitation of the research was the time and the collection of information, therefore, only an analysis of the external scenario of the farm was carried out.publishersversionpublishe

Aplicações de ferramentas de avaliação de impacto socioeconômico e ambiental para agricultura de precisão.

Foram avaliadas ferramentas para aplicação da avaliação de impacto socioeconômico e ambiental para o macroprograma 1 de agricultura de precisão. Duas em particular chamaram a atenção pelo potencial de resposta e foram detalhadas nesse trabalho como exemplos: a Matriz Insumo Produto, representando ferramentas de avaliação inovadoras a serem aplicadas na avaliação da AP e a avaliação tradicional pela Embrapa através do modelo Ambitec. Uma vez que a maioria das tecnologias propostas nesse projeto ainda não estão em fase finalística, optou-se por aplicar o modelo Ambitec nas tecnologias que atingiram a fase de uso pelo produtor e selecionou-se uma, o aplicador seletivo de herbicida Campo Limpo, desenvolvido pela Embrapa Pecuária Sul. O equipamento apresentou um baixo valor na avaliação do Ambitec Social, responsável pela dimensão social, principalmente devido ao baixo impacto econômico, mas um valor significativo em relação ao Ambitec agro, que avalia a dimensão ambiental. Isso pode indicar uma tecnologia que será plenamente aplicada à medida que demandas de ordem ambiental tornem a atividade agrícola mais restrita do que o momento atual

The Portuguese observatory on occupational psychosocial factors: contribution for public health

To achieve the goal of sustainable employment, considering the profile of the Portuguese working population (PWP), is needed a range of strategies to ensure long, productive, and sustainable careers allied with a better quality of working life, health, and wellbeing, but also with public health policies grounded on scientifically validated and reliable data. This is possible through a comprehensive working system approach that ensures workers will be mentally and physically able to remain at work by the balance between work demands and individual resources allied with public health policies transfer into the workplaces by organizations’ leadership and policy makers. The Portuguese Observatory on Occupational Factors (Popsy@Work) aims at addressing this global challenge by: i) digitally collecting psychosocial data on the PWP; ii) implementing and strengthening of a psychosocial occupational health surveillance digital system; iii) providing reference values for the PWP concerning Psychosocial Health; iv) Transferring to society knowledge and best practices; v) Raising awareness on the importance of psychosocial management in occupational settings based on science. Popsy@work is a digital platform that collects and aggregates psychosocial data analytically and creates a visualization hub adding value to data on the PWP and giving science back to society in a usable way, empowering workers, strengthening organizations and grounding public policies. Pospy@Work considers the development of strategic intelligence on levels and inequalities of psychosocial health and well-being in occupational settings by robust metrics and reference data. Creating opportunities for national policy dialogue on inequalities, including the psychosocial health of the PWP through collaboration with diverse sectors identifying and mapping subgroups of populations whose unmet needs require specific outreach measures

The Effects of Sex-Role Attitudes and Group Composition on Men and Women in Groups

The dual impact of group gender composition and sex-role attitudes on self-perceptions and social behavior was explored. Androgynous and stereotyped men and women were placed in groups of skewed sex composition. Subjects\u27 self-descriptions of masculine attributes shifted significantly in the group environment. In some instances, sex role-stereotyped subjects responded most stereotypically when their gender was in the minority in the group. Differences between men and women and between androgynous and stereotyped subjects in sex role-related preferences for group roles and discussion topics were also found
