The broiler production chain is productive, and chicken meat has achieved high export rates to several countries in the world. This study aimed to develop a mobile application that helps the producer to audit the issues of good production practices. The application was developed for Android and programmed in Java. For its development, questions were used, with different weights according to their importance for production. These questions were removed from the items that make up the manuals of good practices used in Brazil. A test was carried out with users to determine the possibility of using the application in the field. After answering all the questions, the user gets a score ranging from 5 to 1 (excellent to bad). It also indicates which questions they did agree with good practices. The test with users showed that the application was easy to understand and enabled users to make decisions that would improve broiler production.

Aims Guided growth has been used to treat coxa valga for cerebral palsy (CP) children. However, there has been no study on the optimal position of screw application. In this paper we have investigated the influence of screw position on the outcomes of guided growth. Methods We retrospectively analyzed 61 hips in 32 CP children who underwent proximal femoral hemi epiphysiodesis between July 2012 and September 2017. The hips were divided into two groups according to the transphyseal position of the screw in the coronal plane: across medial quarter (Group 1) or middle quarter (Group 2) of the medial half of the physis. We compared pre- and postoperative radiographs in head-shaft angle (HSA), Reimer’s migration percentage (MP), acetabular index (AI), and femoral anteversion angle (FAVA), as well as incidences of the physis growing-off the screw within two years. Linear and Cox regression analysis were conducted to identify factors related to HSA correction and risk of the physis growing-off the screw. Results A total of 37 hips in Group 1 and 24 hips in Group 2 were compared. Group 1 showed a more substantial decrease in the HSA (p = 0.003) and the MP (p = 0.032). Both groups had significant and similar improvements in the AI (p = 0.809) and the FAVA (p = 0.304). Group 1 presented a higher incidence of the physis growing-off the screw (p = 0.038). Results of the regression analysis indicated that the eccentricity of screw position correlated with HSA correction and increases the risk of the physis growing-off the screw. Conclusion Guided growth is effective in improving coxa valga and excessive femoral anteversion in CP children. For younger children, despite compromised efficacy of varus correction, we recommend a more centered screw position, at least across the middle quarter of the medial physis, to avoid early revision.

Ecg Interpretation

ABSTRACT Introduction The interpretation of the electrocardiogram (ECG) is fundamental for the identification of cardiovascular diseases, which are among the main causes of death in the world. The acquisition of this competence is essential in the training of the general practitioner and the use of new teaching tools, based on technology such as the use of mobile learning, can facilitate the acquisition of this knowledge. Objectives The objective of this study was to develop and evaluate the usability and the potentiality for the use in medical education of a mobile teaching application for ECG interpretation. Methods With the participation of two health professors and a computer scientist, a systems analyst, a programmer and a graphic designer, a mobile application was developed to teach ECG interpretation using the Java language. For validation analysis, a usability evaluation questionnaire based on the System Usability Scale (SUS) and a questionnaire used to evaluate the suitability of software for use in medical education, previously translated into Portuguese and applied in Brazil, were used. Results The “ECG Fácil” application was developed for off-line use and free access on iOS and Android platforms. In the validation phase of the application, a total of 109 students had free access to the mobile application for 6 weeks and then evaluated usability through a SUS-based questionnaire. The answers to the questionnaire showed good reliability, according to the validation analysis by Cronbach’s alpha coefficient (value: 0.74), and the application presented an excellent acceptance with a mean score on the SUS scale of 85.3. Meanwhile, fifteen faculty members evaluated the application through the questionnaire used to assess the suitability of software for use in medical education, with most agreeing with items indicating that it is suitable for use in medical education. Conclusion The “ECG Fácil” application was considered to be of good usability by students and suitable for educational purpose by teachers. Future studies with this application will be needed to assess the acquisition and retention of knowledge about ECG interpretation by students.
