Equity, diversity and inclusion in a GO-GN project: Adopting participants’ recommendations
No full textEquity, diversity and inclusion (EDI) has been a growing topic within the Open Education community, and some would argue that it has been underpinning the OE discourse since the beginning. However, access to free and online resources alone cannot be considered equitable, diverse and inclusive. For example, most open resources are only available in English, which limits access and reach for many learners around the world (Willems & Bossu, 2012).
EDI has been driving the Global OER Graduate Network’s (GO-GN) agenda since its foundation in 2013, but it was only in 2018 when its first project directly related to DEI was developed. The first phase of GO-GN EDI project focused on EDI practices in Open Education in Africa. Findings of this first stage informed the initial GO-GN guidelines for EDI (Bossu et al., 2019). The findings of phase 1 have also been used as a foundation for phase 2, which focused on EDI in Latin America.
GO-GN currently supports 116 PhD candidates and alumni registered at universities in 26 countries, however, of these members, only 30% conduct their research in the Global South (Weller et al., 2021). The concern is there that, even with all the efforts put into place to be open and a willingness to be diverse, the Global South is still under-represented within this community, which means that GO-GN is not reaching those who could potentially benefit the most from being part of the network. To address this gap and assist the fulfilment of its mission, GO-GN has embarked in a quest to push the EDI agenda by implementing some of the recommendations suggested by the participants of the above projects.
This presentation will explore key findings of these two EDI projects and present a plan for the implementation of some of the recommendations which include increasing support for Global South scholars and researchers in Open Education through a mentoring scheme that would help them to disseminate further their work. This would help to build capacity for GO-GN as well as increase the diversity of work being disseminate through the network. In this presentation, we will also provide an update on the progress of the implementation plan. Conference attendees will be asked to engage and provide their suggestions and views on the plan. We hope that this project will assist better representation from the Global South in GO-GN, and that we have the strategy and implementation tools in place to fulfil our aims in an intercultural, connected and open world.

Endodontic treatment of the deciduous tooth [Il trattamento endodontico del dente deciduo]
No full textOBJECTIVES Carious pathology has a progres-sively degenerative trend which in the absence of adequate treatment can lead to injure the pulp organ, imposing an endodontic approach to the dental element. The aim of this work is to provide the clinical indications, the methods to be undertaken in the end-odontic treatment of the primary teeth, as well as the choice of the most suitable materials, in order to obtain predictable therapeutic results and safeguard the integrity of the elements involved. MATERIALS AND METHODS Endodontic treatment of the primary teeth basically provides two types of procedures: pulpotomy and pulpectomy. Pulpotomy is the endodontic treatment indicated for dental elements where there is exposure of the pulp organ following the re-moval of infected tissue, or con-sequently to a trauma. To carry out the aforementioned treatment it is necessary that the dental elements involved do not show signs of pulp suffering, neither clinical nor radiographic. The pulpotomy procedure involves the removal of the dental tissue affected by carious lesion, the opening of the pulp chamber and the removal of the chamber pulp tissue. Subse-quently, the most suitable material is applied in contact with the root pulp, and finally coronal reconstruction is performed. The purpose of this treatment is to preserve the vitality of the root pulp by promoting a physiological rizalysis process in order to ensure the maintenance of the dental arch space. Pulpectomy is a treatment that involves the removal of the entire pulp organ, both coronal and ra-dicular, and is indicated in cases where the pulp is irreversibly in-flamed or non-vital due to ad-vanced carious lesions or trauma. Following the cavity cleaning and the chamber opening, we pro-ceed, after detecting the working length with the electronic apex lo-cator, with the instrumentation and disinfection of the endodontic space. Subsequently, the root canal obturation is performed, with a material that does not hinder physiological rizalysis, and coronal reconstruction. The purpose of pulpectomy is to control the infec-tion, eliminate the pathogenic bacteria from the root canal sys-tem and maintain the space in the dental arch to ensure the correct eruption of the corresponding permanent dental element. RESULTS The pulpotomy treatment allows a conservative approach to the primary teeth, ensuring a high thera-peutic success thanks also to the current materials available on the market. Pulpectomy allows the elimination of the bacterial load and the consequent regression of ongoing diseases, ensuring the permanence of the primary teeth up to the physiological exchange. CONCLUSIONS Currently, the pediatric dentist can perform predictable therapies and maintain the primary teeth up to physiological exfoliation thanks to the innovative materials and techniques available. All this guaran-tees the improvement of the oral health of the child and a harmoni-ous growth of the stomatognathic system

Deciduous dentition: anatomical study by m-CT
No full textEndodontics is the branch of deciduous teeth pediatric dentistry that deals with the treatment of the root canal system. The goal of therapy is to maintain as long as possible the element in the dental arch to prevent alterations of orthognathodontic, infectious, and functional history and eruptive sequence. Although manual instrumentation has been widely used and still preferred by some practitioners, has limitations that affect the actual ability to clean the channel, the ability to create steps, perforations, dentinal plugs and fractures of the instrument. On the other hand, the disadvantages are the high cost of the instruments in nickel-titanium, which must be frequently replaced, and the risk of compromising the stability of the tooth due to an excessive consumption of dentinal tissue. The use of computed microtomography (μCT) of extracted elements has a considerable advantage in the study of dental hard tissues. The purpose of this study was to analyze the anatomy of the endodontic system of the elements deciduous

Neurovascular Dysfunction in Alzheimer Disease. Assessment of Cerebral Vasoreactivity by Ultrasound Techniques and Evaluation of Circulating Progenitor Cells and Inflammatory Markers
No full textAims:The aims of this study were to assess vascular dysfunction in patients with Alzheimer disease (AD) by investigating cerebral vasomotor reactivity using transcranial Doppler ultrasound (TCD) and to evaluate any correlations between cerebral vasoreactivity and endothelium dysfunction. Moreover, the frequency of circulating progenitor cells (CPCs) and the blood concentration of vascular/inflammatory markers were evaluated.Materials and Methods:We recruited 35 AD subjects and 17 age-matched, sex-matched, and education-matched healthy control subjects. Cerebral vasomotor reactivity was assessed by means of the TCD-based breath-holding index test (BHI). The level of CPCs was evaluated by means of flow cytometry from venous blood samples, while blood vascular/inflammatory markers were measured by means of enzyme-linked immunosorbent assay.Results:Both cerebral assay blood flow velocity in the middle cerebral artery (MCAFV) and BHI values were significantly lower in AD subjects than in healthy controls (P<0.05). A positive trend was found between MCAFV and BHI values and Mini-Mental State Evaluation (MMSE) scores. Moreover, the hematopoietic progenitor cells' count was found to be lower in patients with AD than in controls (P<0.05). Finally, a significantly higher expression of the plasma chemokine CCL-2 was observed in AD patients than in healthy controls.Conclusions:Our results confirm that cerebral hemodynamic deterioration may be a critical marker of cognitive decline. Further studies are needed to investigate the role of circulating CPCs and chemokines as potential contributors to neurovascular dysfunction

Myeloid dendritic cells are decreased in peripheral blood of Alzheimer's disease patients in association with disease progression and severity of depressive symptoms
No full textDendritic cells (DCs) are major orchestrators of immune responses and inflammation. They are migratory cells, which may play a role in Alzheimer's disease (AD), as suggested by prior in vitro studies. With the intent to investigate the clinical relevance of DC modifications in vivo, the present study was aimed to evaluate the levels of blood DCs in AD patients, in relation to the progression of the disease, the severity of its symptoms, and the treatment with acetylcholinesterase inhibitors (AChEIs), a class of drugs used to improve cognitive functioning in people with dementia
