Objective: to identify the incidence of pressure ulcer (PU) and its risk factors in hospitalized patients in the medical-surgical units of a university hospital. Methodology: this is about a descriptive and quantitative study whose data were collected from November 2008 to February 2009 using a instrument containing demographic and clinical data, characterization of PU and Braden Scale after approved by the Ethics Committee of the State University of Londrina with protocol number 170/08. The results were organized in the database Epi info and analyzed using descriptive statistics Results: among 36 patients studied, the incidence of PU was 2.77%, nineteen patients were included already with PU, these were more frequent in the sacral region (50%) and stage III (37%). Hypertension was a statistically significant variable for the development of PU, as well as the patients with longer length of stay. Conclusion: for prevention of UP, it is the function of the nurse to know the possible risk factors, track changes and implement a clinical protocol and all available measures in health care practice. Descriptors: pressure ulcer; risk factors; incidence.RESUMOObjetivo: identificar a incidência de UP e seus fatores de risco em pacientes internados nas Unidades médico-cirúrgicas de um hospital escola.

Dezenove pacientes já apresentavam UP na inclusão do estudo, sendo estas mais frequentes na região sacral (50%) e no estágio III (37%). Em relação aos fatores de risco, a hipertensão foi uma variável estatisticamente significativa para o desenvolvimento de UP, assim como o tempo de internação mais prolongado. Conclusão: para a prevenção de UP cabe ao enfermeiro conhecer os possíveis fatores de risco, acompanhar as alterações clinicas e aplicar um protocolo e todas as medidas disponíveis na pratica assistencial.

Introduction: Confronting the COVID-19 pandemic involves actions in the scope of information, especially in combating false content disseminated by social media. In this sense, medical students, including those belonging to a Trauma and Emergency Academic League, have mobilized to create a media campaign in order to disseminate information about SARS-CoV-2’s aspects to the population. The objective of this work was to report the contribution of the league members to the campaign developed to disseminate reliable scientific content based on simple and objective language about COVID-19. Methodology: A campaign was organized by second to the sixth-year medical students, members of 15 university academic leagues, with the aim to use social media as an information tool for health educational practice. Results: The students from the Trauma and Emergency Academic League made a total of 6 posts on Instagram, using the league’s and the campaign’s accounts. Those posts obtained a total of 1983 views and had the purposed of reaching the general population. The information provided was about self-medication and its risks or benefits, preventive measures against COVID-19 and how to make and use homemade masks. Among the public that accessed the campaign’s profile on Instagram, 70% were women and 80% were between 18 and 34 years old. Discussion: With the reported activities, league students described acquiring knowledge about COVID-19, in addition to teamwork experience and contribution to the fight against the pandemic through the materials production and its dissemination to the population. It allowed innovation in learning and in the access to knowledge, as the pandemic imposed new health-related educational challenges. However, it is noticed that there is a limitation in the posts scope, as they have mostly reached a specific age group. Conclusion: The proper internet usage is essential to combat misleading information in the pandemic context. Therefore, the online dissemination of reliable information with the intent to reach a larger audience indicates academic commitment, especially to social responsibility.
