Digital Security in Educational Training Programs: A Study based on Future Teachers’ Perceptions

Our thanks go to all the future teachers at the University of Granada (Campus Ceuta, Spain) who selflessly participated in this study by responding to the questionnaire.A key aspect of future teacher training in this highly digitalized period of education requires a specific focus on digital skills, especially in the area of security. This study delves into this issue by means of a quantitative, theoretical and systematic review of future teachers currently in training at the Faculty of Education, Economy and Technology of Ceuta of the University of Granada (Spain). The specific intention is to determine their perception of the instruction they receive on digital matters, concretely on cybersecurity during their phase of pre-service. To carry out the project, the study resorted to a descriptive method by submitting the participants to a specifically designed questionnaire entitled “Digital Security Competence Required for Teachers”. Examinations of the psychometric properties of the questionnaire reveal its relevance and reliability. The intention, after applying descriptive and inferential statistics tests, was to determine whether students in pre-service training really feel competent on digital matters or if they feel need more theoretical-practical training, especially in the area of security. The general findings reveal that future female teachers pursuing a university degree in Early Childhood Education, although competent from the techno-pedagogical viewpoint, indicate that attaining a high level of competence in digital security requires more theoretical and practical training. Future male Primary Education teachers, by contrast, perceive themselves as competent in digital security. This perhaps stems from their training (courses and workshops) in Information and Communication Technologies (ICT) and the theoretical and practical instruction they received at the university during courses or during a practicum. This aspect deserves further research because, as highlighted elsewhere, higher education institutions must prioritize instruction on digital security in their teacher programs.Plan of Initiation to Research accorded by the Vice President of Research and Transfer of the University of Granad

Changes in concentrations of haemostatic and inflammatory biomarkers in synovial fluid after intra-articular injection of lipopolysaccharide in horses

Abstract Background Septic arthritis is a common and potentially devastating disease characterized by severe intra-articular (IA) inflammation and fibrin deposition. Research into equine joint pathologies has focused on inflammation, but recent research in humans suggests that both haemostatic and inflammatory pathways are activated in the joint compartment in arthritic conditions. The aim of this study was to characterize the IA haemostatic and inflammatory responses in horses with experimental lipopolysaccharide (LPS)-induced joint inflammation. Inflammation was induced by IA injection of LPS into one antebrachiocarpal joint of six horses. Horses were evaluated clinically with subjective grading of lameness, and blood and synovial fluid (SF) samples were collected at post injection hours (PIH) -120, −96, −24, 0, 2, 4, 8, 16, 24, 36, 48, 72 and 144. Total protein (TP), white blood cell counts (WBC), serum amyloid A (SAA), haptoglobin, iron, fibrinogen, thrombin-antithrombin (TAT) and d-dimer concentrations were assessed in blood and SF. Results Intra-articular injection of LPS caused local and systemic signs of inflammation including increased rectal temperature, lameness and increased joint circumference and skin temperature. Most of the biomarkers (TP, WBC, haptoglobin, fibrinogen and TAT) measured in SF increased quickly after LPS injection (at PIH 2–4), whereas SAA and d-dimer levels increased more slowly (at PIH 16 and 144, respectively). SF iron concentrations did not change statistically significantly. Blood WBC, SAA, haptoglobin and fibrinogen increased and iron decreased significantly in response to the IA LPS injection, while TAT and d-dimer concentrations did not change. Repeated pre-injection arthrocenteses caused significant changes in SF concentrations of TP, WBC and haptoglobin. Conclusion Similar to inflammatory joint disease in humans, joint inflammation in horses was accompanied by an IA haemostatic response with changes in fibrinogen, TAT and d-dimer concentrations. Inflammatory and haemostatic responses were induced simultaneously and may likely interact. Further studies of interactions between the two responses are needed for a better understanding of pathogenesis of joint disease in horses. Knowledge of effects of repeated arthrocenteses on levels of SF biomarkers may be of value when markers are used for diagnostic purposes

Synovial incorporation of polyacrylamide hydrogel after injection into normal and osteoarthritic animal joints

Polyacrylamide hydrogel (PAAG) is a non-toxic, non-degradable synthetic product, used for years in the augmentation of soft tissues. Preliminary results in animals and humans have suggested long-lasting beneficial effects on symptoms of osteoarthritis (OA). The aim of this histopathological study was to investigate whether intra-articular injection of PAAG is integrated into synovial tissue in normal and OA animal joints, and if this integration is sustained.(A) A prospective, controlled, longitudinal study of normal knee joints injected with PAAG was performed in 10 rabbits, following the animals up to 1 year, and (B) a post mortem examination was carried out up to 2 years post-injection on 18 horse joints which had previously been treated with 1-2 injections of 2 ml PAAG for clinically and radiologically diagnosed OA.Integration of the injected gel was evident at day 10 in the rabbit and by day 14 in the horse, with proliferation and invasion of synovial cells into the gel. By day 90 in rabbit joints and day 30 in horse joints, the gel had formed a sub-synovial layer, which was traversed by thin strands of connective tissue with vessels and covered by a synovial lining facing the joint cavity. This histological appearance persisted up to 2 years post-injection in horse joints.Intra-articular injection of PAAG results in a stable, long-lasting sub-synovial layer of gel traversed with thin strands of connective tissue. Further studies to explore potential effects on synovial inflammation and pain are warranted
