Supervised Teaching Practice in Initial Teacher Education of Early Childhood Teachers in Portugal
Paulo Viana,Marta Abelha,Helena Inês,Patrícia Gramaxo,Filipa Seabra The Pacific Early Childhood Education Research Ass 2023 Asia-Pacific journal of research in early childhoo Vol.17 No.3
Supervised teaching practice (STP) is a fundamental stage of initial teacher education, including preschool educators and teachers of the first cycle of basic education (1st CBE), which impacts their future practices. Our objectives were: a) to characterize STP in the curricula of degrees habilitating teachers for preschool education and teaching of the 1st CBE; b) to gather indicators about the process of STP implemented by the same cycles of studies; and c) to describe the improvement recommendations by the Agency for Evaluation and Accreditation of Higher Education (A3ES) to the same cycles of studies, concerning STP. The study was based on the documentary analysis of the plans of study, and A3ES reports on the initial teacher education programs preparing preschool educators and teachers of the 1st CBE of public higher education institutions (HEI) in Portugal, available during the academic year of 2020/2021. The results point to discrepancies in the definition of contact hours and the number of hours dedicated to supervised teaching practice across HEI. The recommendations for improvement by the A3ES about STP encompass cooperating teachers, the accompaniment by the HEI, and the conditions of reception at the cooperating schools.

Can a spontaneous smile invalidate facial identification by photo-anthropometry?
Pinto, Paulo Henrique Viana,Rodrigues, Caio Henrique Pinke,Rozatto, Juliana Rodrigues,da Silva, Ana Maria Bettoni Rodrigues,Bruni, Aline Thais,da Silva, Marco Antonio Moreira Rodrigues,da Silva, Ricar Korean Academy of Oral and Maxillofacial Radiology 2021 Imaging Science in Dentistry Vol.51 No.3
Purpose: Using images in the facial image comparison process poses a challenge for forensic experts due to limitations such as the presence of facial expressions. The aims of this study were to analyze how morphometric changes in the face during a spontaneous smile influence the facial image comparison process and to evaluate the reproducibility of measurements obtained by digital stereophotogrammetry in these situations. Materials and Methods: Three examiners used digital stereophotogrammetry to obtain 3-dimensional images of the faces of 10 female participants(aged between 23 and 45 years). Photographs of the participants' faces were captured with their faces at rest (group 1) and with a spontaneous smile (group 2), resulting in a total of 60 3-dimensional images. The digital stereophotogrammetry device obtained the images with a 3.5-ms capture time, which prevented undesirable movements of the participants. Linear measurements between facial landmarks were made, in units of millimeters, and the data were subjected to multivariate and univariate statistical analyses using Pirouette<sup>®</sup> version 4.5 (InfoMetrix Inc., Woodinville, WA, USA) and Microsoft Excel<sup>®</sup> (Microsoft Corp., Redmond, WA, USA), respectively. Results: The measurements that most strongly influenced the separation of the groups were related to the labial/buccal region. In general, the data showed low standard deviations, which differed by less than 10% from the measured mean values, demonstrating that the digital stereophotogrammetry technique was reproducible. Conclusion: The impact of spontaneous smiles on the facial image comparison process should be considered, and digital stereophotogrammetry provided good reproducibility.

Background: Prothrombin complex concentrate (PCC) and fresh frozen plasma (FFP) are commonly used to manage bleeding in patients during cardiac surgery. However, the relative efficacy and safety of these 2 strategies remain uncertain. Methods: MEDLINE, Embase, and Cochrane were searched for studies comparing PCC and FFP in patients who underwent cardiac surgery complicated by bleeding. Review Manager (RevMan) ver. 5.4 (Nordic Cochrane Centre, The Cochrane Collaboration) was used for statistical analysis. Binary and continuous outcomes were compared using pooled risk ratios and mean differences, respectively. The meta-analysis protocol was registered in the International Prospective Register of Systematic Reviews under protocol number CRD42022379144. Results: We included 8 studies with 1,500 patients, of whom 613 (40.9%) received PCC. The mean follow-up period ranged from 28 to 90 days. The PCC group had significantly lower chest tube drainage at 24 hours (mean difference [MD], -148.50 mL; 95% CI, -253.02 to -43.99 mL; p=0.005; I2=42%). Fewer units of red blood cells (RBCs) were transfused within the first 24 hours (MD, -1.02 units; 95% CI, -1.81 to -0.24 units; p=0.01; I2=56%), and fewer patients required RBC transfusion within the first 24 hours (risk ratio, 0.85; 95% CI, 0.78–0.93; p<0.007; I2=45%) in the PCC group. There were no statistically significant differences in secondary outcomes. Nonetheless, a subgroup analysis of randomized controlled trials failed to corroborate the results obtained from the main analysis. Conclusion: Our findings suggest that PCC can be effective, without increased adverse events, when compared with FFP in patients undergoing cardiac surgery complicated by bleeding.
