Bacterial nanocellulose (BNC) has attracted considerable attention in the field of biomedical engineering due to its potential for use in bone regeneration applications. The present study investigates the in vitro and in vivo efficacy of bacterial nanocellulose (BNC) combined with calcium and cerium ions (BNC-Ce:CaP) in bone regeneration applications. XRD analysis confirmed the presence of monetite and hydroxyapatite phases in BNC-CaP, while BNC-Ce:CaP revealed an additional brushite phase.

- Advances in implants and biological therapies have improved trauma care, especially for complex cases like Schatzker type V tibial plateau fractures.
- This study evaluates three patients treated with open reduction and internal fixation plus tricalcium phosphate bone void filler, assessing outcomes through various scoring systems.
- Results showed high patient satisfaction and low pain levels, with good range of motion and no significant complications, indicating that tricalcium phosphate may enhance recovery by supporting healing and integration.
Objectives: to construct and validate an educational game on biosafety in the Central Sterile Supply Department of a hospital in Curitiba, PR.
Methods: the study was conducted using a quantitative approach, employing applied and technological research with an exploratory design. The process was divided into six stages, from the definition of the theme to the validation and application of the game.
To investigate psychosocial factors at work, sleep characteristics, and the correlation between these aspects in healthcare workers. A cross-sectional e-survey study was conducted with 125 workers of the Brazilian healthcare system, mostly from the Southeast region, from June 2021 to April 2022. Self-administered questionnaires in Google Forms were used to collect data on personal and occupational characteristics, psychosocial factors (Copenhagen Psychosocial Questionnaire), and sleep quality (Pittsburg Sleep Quality Index).
