Views0Objective:
the objective was to assess the level of physical activity (LPA) and the quality of life QL of the professionals who work in ICU.
Method:
this was a cross-sectional study carried out in Adult ICUs. LPA was assessed by the International Questionnarie of Physical Activity – short form (IQPA-SF) and the QL by the Medical Outcomes Study 36 (SF-36) questionnaire.
Results:
it was classified active 50.89% out of a total of 59 professionals. Nursing technicians were considered the most active with 60.6%. The QL of the professionals who were considered active were better when compared to inactives, with statistical differences to the category of physical aspects limitation, social aspects and mental health. The working hours were higher than recommend, the physicians were higher than the physical therapist, nurses and technicians nurses (p = 0.046).
Conclusion:
physically active professionals who work in ICU had higher quality of life probably why have lower hours of work and consequently more free time to engage in physical activity.

Objective:
to identify factors that lead the teacher to experience violence in their pedagogical practice in health education.
Method:
research with a qualitative approach, based on the Grounded Theory, conducted with 11 professors of the nursing course of a public university in the central region of Brazil in 2020 and 2021. Online semi-structured interviews were analyzed partially in the light of the Constructivist Grounded Theory.
Results:
factors that lead lecturer to experience violence are characterized by institutional culture, gender, professor’s perception of violence, and the triggers that drive students to commit violence. Social status and inequalities lead to positions of domination and, consequently, create a fertile ground for violence.
Final Considerations:
analyzing violence under Bourdieu’s theory, it is clear that student violence towards lecturer and the reports contained in this study deserve pedagogical reflection. However, it is necessary to include these discussions as a background in teaching environments.

Objective:
To analyze the spatial pattern of tuberculosis in Indigenous peoples from the State of Pará and its correlation with income transfer.
Methods:
Ecological study, with 340 cases reported in Indigenous peoples in the State of Pará, Brazil, in the period 2016-2020. The study performed a descriptive analysis and calculation of incidence rates with smoothing by the local empirical Bayesian method. The Global Moran index assessed the autocorrelation of the rates with income transfer data, p<0,05.
Results:
The Marajó and metropolitan mesoregions of Belém had the highest tuberculosis rates, and a reduced number of people benefited from income transfer (high-low correlation). The study identified high rates, and a significant number of people benefited from financial aid (high correlation high), I=0.399, p=0.027 in the Southwest.
Conclusions:
The spatial autocorrelation between tuberculosis and access to income transfer programs constitutes a relevant subsidy for the formulation of social protection policies and may impact the disease control actions in Indigenous territories, valuing the epidemiological heterogeneity identified in the mesoregions.

Objectives:
to analyze subjective experiences related to adaptation to remote care by users with eating disorders during the COVID-19 pandemic.
Methods:
a descriptive study with a qualitative approach conducted with users of an eating disorders outpatient clinic. A semi-structured remote interview was applied using the Google Meet application. The data were submitted to lexical analysis using ALCESTE software and discussed in the light of scientific evidence.
Results:
the remote appointment is a positive strategy but not a substitute for the face-to-face modality. The research cited financial savings, closer contact with professionals, and flexibility of service schedules as advantages. It pointed out the difficulty in clinical evaluation concerning weight, vital signs, and poor mastery of technology as limitations.
Final Considerations:
the study induces discussion about the systematization of remote care, which, during the COVID-19 pandemic, were responsible for providing a greater sense of support to people with eating disorders.

Objectives:
to describe the training profile of Brazilian intensive care nurses.
Methods:
a cross-sectional study carried out in two stages: a structured, self-administered questionnaire; mapping of the national supply of lato sensu postgraduate courses. Data was collected on the sociodemographic profile, training process and characterization of the courses.
Results:
in the first stage, 202 respondents were obtained. The majority were women (79.2%), aged between 26 and 45 (80.7%), graduated less than 5 years ago (44%), through lato sensu postgraduate courses (55.5%), which were marked by the absence of laboratory practice (57.5%) and guided tours (42.5%). In the second stage, 457 courses were identified, with face-to-face teaching (58.9%), a workload of 360 to 420 hours (51.2%), a duration of up to 6 months (41.8%) and variation in the sub-area of training.
Conclusions:
there was a predominance of professionals graduating from lato sensu post-graduate courses, with essentially theoretical teaching and heterogeneity in terms of modality, workload and sub-area of training.
