Introdução: A doação de sangue é um ato capaz de salvar vidas. Quando a triagem sorológica é positiva, a bolsa de sangue é descartada. Este trabalho teve como objetivo avaliar a prevalência de descarte de bolsas de sangue em razão da positividade dos testes de triagem para sífilis.Métodos: Foi realizado um estudo epidemiológico observacional, com avaliação transversal e da tendência temporal da positividade do VDRL de acordo com as variáveis epidemiológicas, a partir de dados coletados no banco de sangue do Hemocentro de Sergipe das doações ocorridas de 1 de janeiro de 2007 a 31 de dezembro de 2018.Resultados: Do total de 308.953 doações de sangue, 4.594 bolsas (1,48%) foram descartadas devido a positividade para sífilis. A positividade foi significativamente maior no sexo masculino (OR = 1,14). Houve aumento significativo da prevalência com o aumento da faixa etária, de 0,63% (IC95% 0,51-0,760 em menores de 20 anos até 4,54% (IC95% 3,88-5,30) em pessoas com 60 anos e mais. Entre o período de 2007-2011 foi identificada uma tendência de crescimento da soroprevalência para sífilis (APC = 31,4) seguida pela estabilização do número de descarte de bolsas nos últimos anos.Discussão: O estudo identifica que, apesar de ter havido um aumento significativo no período inicial, a tendência foi de estabilidade nos últimos anos avaliados. É importante destacar a falta de um exame que indique concretamente a presença ativa da sífilis, pois todos os testes podem permanecer como cicatrizes por longos períodos, mesmos em pessoas com o tratamento adequado.

Stress is a multidimensional and multifaceted phenomenon that reflects and conditions individual and organizational quality of life. However, given specific work contexts in which there are disproportionate demands, lack or reduced support from the organizational structure, dull treatment of employees, lack of recognition, and the existence of a conflictual environment, it leads to relatively high levels of organizational stress. In turn, burnout arises from the crisis in relationships with work. Its main manifestations are emotional and physical exhaustion, cynicism, and professional ineffectiveness, arising from feelings of exhaustion, energy depletion, increased apathy with work, reduced effectiveness, and negativism with the professional routine. In this follow-up, a bibliometric analysis between 1980 and 2022 was conducted to explore the most relevant authors, documents, and journals, the trends identified in the publications, and the collaborations between countries in the field of study.

Universities are committed to preparing students to think creatively and entrepreneurially. According to Pinto, a university is a place of professional education that promotes the articulation of more effective pedagogical alternatives, the integration of theory and practice, and the resolution of real-world problems through the generation of critical and reflective actions informed by concrete experiences. Educational innovation influences the transformation of methodologies, instructional methods, and students' learned skills. Combining innovation and learning increases public awareness of this issue. This chapter aims to determine whether innovation is incorporated into teaching, whether it is incorporated into course planning, what is the students' perception of it, and the differences between cultures – taking into consideration higher education institutions from Portugal and Poland.

A 14-year-old white female patient with allergic rhinitis, reported a 4-week history of pruritic, lichenoid and erythematous papules and plaques involving first cervical region and after throughout the body. The histopathology was indicative of Langerhans cell histiocytosis. Laboratory and imaging tests showed no impairment of other organs. Lesions regressed after oral prednisone for 2 months. Currently, the patient remains asymptomatic without medication. We highlight the rarity of this disease and the importance of its early recognition. It is extremely important to maintain periodic follow-up to evaluate possible recurrences.
