This study aims to develop a realistic 3D printing-based simulator for the training and planning of the left atrial appendage occlusion (LAAO) to be used in the cath lab.

Starting from a pre-operative computed tomography dataset of a patient already treated with LAAO, the model was obtained, consisting in the right and left heart, opportunely assembled to replicate the position and orientation of the patient's anatomy while lying on the cath lab table. Different 3D printing techniques and materials were used to mimic the interaction between the cardiac tissue and the clinical instrumentation. The simulator was tested in the cath lab under proper image guidance by three LAAO expert operators. The clinicians were required to assign a score in terms of realism to each material used to fabricate the fossa ovalis and the LAA.

The simulated interventions were successfully performed by the operators, who were able to navigate in the system and release the occluder device as during a real procedure. The intraoperative images acquired during the simulations were highly comparable with data from a real intervention, with a mean percentage difference below 10%.

This study demonstrated the feasibility of the proposed simulator to faithfully replicate the LAAO procedure and its potentiality to be used for multiple purposes, including the training of the young clinicians, the evaluation of the most complicated cases and the design of novel occluder devices, in a fully realistic setting.

The purpose of this paper is to present the Italian validation of the standards for communities for children and adolescents (SCIA) Questionnaire, an evaluation tool of communities quality standards, based on the “Service Standards for Therapeutic Communities for Children and Young People – 2nd edition” of the Community of Communities (2009), that enables an empirical, multidimensional and complex evaluation of the therapeutic community (TC) “system”. It is a self-report that sets out and measures variables that allow to get an overview of organisational models and the possible development areas to improve the effectiveness of the protection of child and adolescents in community treatment. The validation and a preliminary analysis to develop a short version of the SCIA are presented.

The questionnaire (composed, in the extended form, by 143 items) was administered to 101 community workers, 20 males (19.8 per cent) and 81 females (81.2 per cent) aged between 24 and 61 years (M=36.20, SD=8.4). The analysis of reliability (Cronbach’s α) and a series of exploratory factor analysis allowed to eliminate redundant or less significant items.

The short form of the self-report consists of 67 items, divided into seven subscales, which explore different areas of intervention in TCs. Despite the limitations due to the small sample size, the utility of this tool remains confirmed by its clinical use and the development of good operating practices.

The SCIA Questionnaire responds to the need to adopt empirical variables in the process of evaluation of the communities. The SCIA is also a useful tool for clinical evaluation, as it allows a detailed observation of residential community treatment with children and adolescents that allows to analyse and monitor the structural and organisational aspects and the quality of practices that guide the interventions.

Recognizing novel entrepreneurial opportunities arising from a crisis is of paramount importance for firms. Hence, understanding the pivotal factors that facilitate firms in this endeavor holds significant value. This study delves into such factors within a representative empirical context impacted by a crisis, drawing insights from existing literature on opportunity recognition during such tumultuous periods.

The authors conducted a qualitative inspection of 14 Italian firms during the COVID-19 pandemic crisis. The authors collected a rich body of multi-source qualitative data, including 34 interviews (with senior managers and entrepreneurs) and secondary data (press releases, videos, web interviews, newspapers, reports and academic articles) in two phases (March–August 2020 and September–December 2020).

The results suggest the existence of a process model of opportunity recognition during crises based on five entrepreneurial influencing factors (entrepreneurial knowledge, entrepreneurial alertness, entrepreneurial proclivity, entrepreneurial personality and entrepreneurial purpose).

Various scholars have highlighted that, in times of crises, it is not easy and indeed very challenging for entrepreneurs to identify novel entrepreneurial opportunities. However, recent research has shown that crises can also positively impact entrepreneurs and their capacity to identify new entrepreneurial opportunities. Given these findings, not much research has analyzed the process by which entrepreneurs identify novel entrepreneurial opportunities during crises. This study shows that some entrepreneurial influencing factors are very important to identify new entrepreneurial opportunities during crises.

This paper aims to present a pilot study’s aims to identify opportunities and limits deriving from the use of low-cost 3D printing (3DP), fused deposition modelling (FDM), open-source technologies in co-design and co-production processes involving persons with rheumatic diseases (RDs).

In the paper, the authors outline why the use of low-cost, entry-level FDM can be meaningful for this scenario, implying a complete sharing of the design and the production phases of small assistive devices. The +TUO process is composed of several stages, among which the generative session represents the core.

This study highlights as the introduction of this low-cost technology in co-generative processes with people with RDs is a real challenge that can lead to new products and solutions, and that can sustain a social and local manufacturing approach for people facing a specific disablement.

This research is a first step of a broader research, new researches are going to explore further details related with the technology and of the adopted method.

Involving actively, the end user during the creation process can bring advantages such as meeting more precisely their needs and create innovative products, as shown in the text.

For people living with RDs, an occupation is important to sustain a process of empowerment. Adopting assistive devices supports daily activities and facilitates the occupation.

+TUO is a pilot study that explore a topic already discussed in the scientific arena, without focusing on the specific use of low-cost 3DP technologies.
