A comparative study on the motor-autobiography of Italian kindergarten and primary school will be teachers
No full textA perspective of evaluation based on authentic assessment highlights the ethical and aesthetic aspects of education as well as the learning aspect of the assessment, which is expressed in a dialogic mode and offers a sharing process that transforms the assessment into an important stage of the learning path. This type of evaluative inquiry shifts the focus of research from the product, which is represented in the motor field by execution, performance or gesture, to the understanding of learning strategies for students, enabling them to reflect on their own elaboration processes and development of the educational process through the use of the teaching of the body and movement. The expected results, therefore, will provide a redefinition of the educational needs of the students that are created due to the greater awareness of their education – motor path

Italian school and integration: the strategic role of movement education
No full textSince the Sixties in Italy, the history of education and students with disability, regardless of the type of handicap and e
degree of disability, is part of the evolution of the school system. The Italian education system compared to the European one
has made significant process, succeeding in a short space of time to generalize the process of inclusion of disabled people into
normal schools, defining it as “integration”. In the other European countries, however, this process has not only been slower, but
has been mainly a minority function, linked more to the field of educational research rather than to a political choice. In fact, while
in Italy it is worth noting this new political reality, in the other European countries and in the same community agencies the rise of
this phenomenon in relation to politics and legal acts is much later. Italian school has always given a significant educational
value for people with disabilities, due to it being in an age range – scholastic – in which the development and growth of their
residual abilities are more effective and more consistent in the following period (Bosio, 2005); therefore, the disability should be
accepted and recognized as such, without it implies a reduction for the disabled child of his value as a person helping him to find
alternative ways to those lost, patterns life of conduct that address those made impossible by the lesion (Bosio, 2005). In Italy as
early as the nursery school, the experience of children with disabilities is to be considered significant for a better integration in
the primary school before and in the secondary school after, because it is the first step necessary for the start of this process.
Obviously the presence of a person with special needs, requires new needs in the school context and beyond, but also for
immediate deployment of an increasing number of specialized teachers and educators. Motor activities in this context,
contributing to the creation of strong links between the disabled and the outside world, become suitable instruments in the
process of social integration, empowerment and growth, since the comparison with the others, the perception of its efficiency,
own self-regulatory capacity, can give life to an environment rich in significant stimulation. This socializing function is a even
more valuable in the disabled person, in order to participate and experience the life of the latter group is a strong possibility of
development and allows him to learn more appropriate patterns of behavior in order to live in society, advancing the subjective
and relational welfare, thus improving their quality of lif
Enamel matrix derivative and autogenous bone graft for periodontal regeneration of intrabony defects in humans: A systematic review and meta-analysis
Full text linkThe combination of enamel matrix derivative (EMD) with an autogenous bone graft in periodontal regeneration has been proposed to improve clinical outcomes, especially in case of deep non-contained periodontal defects, with variable results. The aim of the present systematic review and meta-analysis was to assess the efficacy of EMD in combination with autogenous bone graft compared with the use of EMD alone for the regeneration of periodontal intrabony defects. A literature search in PubMed and in the Cochrane Central Register of Controlled Trials was carried out on February 2019 using an ad-hoc search string created by two independent and calibrated reviewers. All randomized controlled trials (RCTs) comparing a combination of EMD and autogenous bone graft with EMD alone for the treatment of periodontal intrabony defects were included. Studies involving other graft materials were excluded. The requested follow-up was at least 6 months. There was no restriction on age or number of patients. Standard difference in means between test and control groups as well as relative forest plots were calculated for clinical attachment level gain (CALgain), probing depth reduction (PDred), and gingival recession increase (RECinc). Three RCTs reporting on 79 patients and 98 intrabony defects were selected for the analysis. Statistical heterogeneity was detected as significantly high in the analysis of PDred and RECinc (I2 = 85.28%, p = 0.001; I2 = 73.95%, p = 0.022, respectively), but not in the analysis of CALgain (I2 = 59.30%, p = 0.086). Standard difference in means (SDM) for CALgain between test and control groups amounted to -0.34 mm (95% CI -0.77 to 0.09; p = 0.12). SDM for PDred amounted to -0.43 mm (95% CI -0.86 to 0.01; p = 0.06). SDM for RECinc amounted to 0.12 mm (95% CI -0.30 to 0.55. p = 0.57). Within their limits, the obtained results indicate that the combination of enamel matrix derivative and autogenous bone graft may result in non-significant additional clinical improvements in terms of CALgain, PDred, and RECinc compared with those obtained with EMD alone. Several factors, including the surgical protocol used (e.g. supracrestal soft tissue preservation techniques) could have masked the potential additional benefit of the combined approach. Further well-designed randomized controlled trials, with well-defined selection criteria and operative protocols, are needed to draw more definite conclusions.The combination of enamel matrix derivative (EMD) with an autogenous bone graft in periodontal regeneration has been proposed to improve clinical outcomes, especially in case of deep non-contained periodontal defects, with variable results.

Cell-based therapies for the surgical treatment of periodontal intrabony defects: a systematic review
No full textOBJECTIVE: The aim of the study is to investigate the efficacy of cell-based therapy in the surgical treatment of periodontal intrabony defects.MATERIALS AND METHODS: PRISMA guidelines were followed, and the study protocol was registered in PROSPERO. Electronic and hand searches were carried out on electronic databases and major international journals of periodontology. All randomized clinical trials (RCTs) comparing cell-based therapies combined with surgery to surgery alone for the treatment of periodontal intrabony defects were considered. Quality assessment was performed using the Cochrane Risk of Bias Tool for randomized clinical trials (RoB 2). Quantitative evaluation of data was performed by meta-analysis.RESULTS: Five hundred twenty-eight records were initially screened and 5 RCTs fulfilling the eligibility criteria were included. Periodontal ligament stem cells, dental pulp stem cells, periosteum-derived stem cells, gingival fibroblasts and their associated stem cells were used in combination with different surgical techniques to treat intrabony periodontal defects. Meta-analysis showed a statistically significant effect in favor of cell-based groups for clinical attachment level gain (p=0.004), with a difference in means of 1.7 mm (95% CI 0.5; 2.9). This was replicated for intrabony defect depth reduction (p=0.006), with a difference in means of 1.3 (95% CI 0.4; 2.3).CONCLUSIONS: Cell-based therapies have been positively applied for the surgical treatment of intrabony periodontal defects with promising results. However, the results obtained should be interpreted with caution due to the low number of available RCTs, the study design heterogeneity, and the limited extension of the follow-up
Periodontitis, low-grade inflammation and systemic health: A scoping review
No full textBackground and objectives: Periodontitis is a multifactorial chronic inflammatory infectious disease in which an infection is necessary, but not sufficient, for development of the condition. Individual susceptibility strictly linked to the immune and inflammatory response of the organism must also be present. Low-grade inflammation (LGI) is a systemic status of chronic sub-clinical production of inflammatory factors. This condition represents a risk factor for many chronic diseases including diabetes, cardiovascular disease, cerebrovascular disease, neurodegenerative disease and cancer. This scoping review aims to clarify, summarize and disseminate current knowledge on the possible link between periodontitis, LGI and systemic health. Materials and Methods: PRISMA Extension for Scoping Reviews guidelines were followed. An ad-hoc created keyword string was used to search the electronic databases of PubMed/Medline, Embase, The Cochrane Library and ClinicalTrials.gov. A hand search of specialized journals and their reference lists was also performed. Results: 14 studies that respected eligibility criteria were selected and analyzed. There is emerging evidence of strong links between periodontitis, LGI and systemic health. On the one hand, periodontitis influences the systemic status of LGI and on the other hand, the systemic production of inflammatory factors affects periodontitis with a bidirectional connection. Conclusions: LGI and the subsequent onset of a systemic inflammatory phenotype can be considered the common substrate of many chronic inflammatory diseases including periodontitis, with multiple mutual connections between them. Understanding of the biological principles and mechanisms underlying such a complex interrelationship could lead to significant improvements in the field of personalized diagnostics and therapeutic protocols
Self-assessment of sports- Motor skills for will-be nursery and elementary teachers in Italy
No full textThe present academic Italian system in force as of 2011-2012, describing again the didactic-disciplinary features
of the degree course of Science of Primary Education, in response to the formative needs that appear in the
nursery and primary Italian school, making more and more use of qualified teachers, raises the issue of the
importance that in the curricula of future teachers there should be both knowledge and skills that relate to
different fields among including the motor-sport field. This research aims to evaluate, through a multiple-choice
questionnaire, the way the first year students of the Degree Course in Primary Formation Sciences perceive their
own basic skills regarding sports-motor activities and analyze if the students are able or unable to make ad
appropriate self-assessment. At the end of the theoretical course of the first semester, each student has been
given a questionnaire on the motor autobiography composed of seven closed- questions concerning: structure of
spatial and temporal organization; orientation; dexterity; coordination; balance; posture. A high percentage of
students has considered their posture (50%) and structure of body schema incorrect (69%). A significant
percentage has considered themselves unable to evaluate their own motor skills at the end of the theoretical
course; this makes more necessary and important a change of docimology perspective on the courses of
didactics of motor activities. After the experience of self-assessment of sports-motor skills, students will have
the opportunity to attend the specific laboratory of psychomotor activities implementing the theoretical
knowledge during the degree course modifying them in a practical knowledge through laboratory teachin
Bacterial adhesion to grade 4 and grade 5 turned and mildly acid-etched titanium implant surfaces: An in vitro and ex vivo study
Full text linkThe aim of the present study was to investigate the bacterial adhesion to titanium (Ti) implant surfaces, different for composition and topographic features. Grade 4 and 5 turned (T-4, T-5,) and mildly acid-etched (MA-4, MA-5) Ti 6 × 1 mm disks were topographically analyzed by scanning electronic microscopy and 3D profilometry. Bacterial cultures (Streptococcus sanguinis) were in vitro seeded and, after two and six hours, adherent bacteria were quantified by colony-forming unit (CFU) counting. Ti samples were also exposed to the oral environment of six periodontally healthy volunteers and, after 12 h, the formed biofilm was evaluated by CFU counting. Inter-group differences were tested by the Mann–Whitney U-Test (α = 0.05). MA surfaces were significantly rougher than T ones, whereas no difference between grade 4 and grade 5 disks was detected. Significantly higher in vitro bacterial adhesion for MA than T disks was shown at two and six hours. Significantly higher values of CFU counting for MA than T surfaces and for grade 5 than grade 4 disks were found at the 12 h-ex vivo test. Bacterial adhesion showed to be sensitive to both Ti surface topography and composition, with possible implications on peri-implant tissue health maintenance
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
