Background Dental professionals are subjected to higher risks for musculoskeletal disorders (MSDs) than other professional groups, especially the hand region. This study aims to investigate the prevalence of hand complaints among dentists (Ds) and dental assistants (DAs) and examines applied therapies. Methods For this purpose, an online questionnaire analysed 389 Ds (240female/149male) and 406 DAs (401female/5male) working in Germany. The self-reported data of the two occupational groups were compared with regard to the topics examined. The questionnaire was based on the Nordic Questionnaire (self-reported lifetime, 12-month and 7-day MSDs prevalence of the hand, the conducted therapy and…

Analysis of Spanish nursing students' knowledge in palliative care. An online survey in five colleges.

2020

Abstract Along their professional career, nurses can find patients who require palliative care (PC). It is necessary to have at least a basic education in this area, that should be acquired during their university education. The objective of this descriptive online-survey set in five nursing Colleges was to analyze Spanish nursing students’ knowledge in PC, offering an image of the status of education in PC. 619 students took an online questionnaire with the Spanish version of the Palliative Care Quiz for Nurses (PCQN-SV), which also collected information about their education in the field of PC. Univariate and bivariate analyses were performed, and a predictive binary logistic regression m…

Spanish Nurses’ Knowledge about Palliative Care. A National Online Survey

2021

(1) Background: Nurses can find people with advanced diseases or in their last days of life during their professional careers and in many different care settings. For this reason, they need to have at least a basic level of palliative care education since they are the professional cohort treating these patients in a very close way. This research aims to determine the level of knowledge in palliative care of Spanish nurses and establish any possible difference based on their experience and training in palliative care. (2) Methods: A cross-sectional design using survey methods (distributed an online questionnaire) aimed at Spanish registered nurses. A validated questionnaire (PCQN-SV) was use…

Computer-aided detection of cerebral microbleeds in susceptibility-weighted imaging.

2014

Susceptibility-weighted imaging (SWI) is recognized as the preferred MRI technique for visualizing cerebral vasculature and related pathologies such as cerebral microbleeds (CMBs). Manual identification of CMBs is time-consuming, has limited reliability and reproducibility, and is prone to misinterpretation. In this paper, a novel computer-aided microbleed detection technique based on machine learning is presented: First, spherical-like objects (potential CMB candidates) with their corresponding bounding boxes were detected using a novel multi-scale Laplacian of Gaussian technique. A set of robust 3-dimensional Radon- and Hessian-based shape descriptors within each bounding box were then ex…

Comparing the cycling behaviours of Australian, Chinese and Colombian cyclists using a behavioural questionnaire paradigm.

2020

Cyclists are vulnerable road users and face disproportionately high rates of road trauma, especially in low- and middle-income countries. Behaviour of road users is a system outcome, and thus studying cyclist behaviours can identify problems in the whole road transport system and assist in generating long-lasting, cost-effective solutions to promote cyclist safety. This study aims to investigate the similarities and disparities of cycling behaviour among countries with different income levels and cycling prevalence, and the relationships among cyclist demographic characteristics, behaviours and crash involvement. It applies the Cycling Behaviour Questionnaire (CBQ) to measure the behaviour …

Scripted Collaboration and Group‐Based Variations in a Higher Education CSCL Context

2009

Scripting student activities is one way to make Computer‐Supported Collaborative Learning more efficient. This case study examines how scripting guided student group activities and also how different groups interpreted the script; what kinds of roles students adopted and what kinds of differences there were between the groups in terms of their activities. Seven small groups of higher education students participated in the study. According to the findings, scripting enhanced collaboration and ensured that all groups were able to complete the task, but despite the script the groups' activities varied during the task and the script could not guarantee any “high‐level” participation by all stud…

The Internationalisation of Higher Education in Brazil: Analysis of a Spanish-Brazilian Scientific Cooperation Project in CAL

2012

[EN] Over the past few years, the internationalisation of Higher Education has become a priority in Brazilian educational policies. The importance of internationalisation has become apparent thanks to numerous initiatives, ranging from the increase in funding for graduate and postgraduate research stays abroad to projects of scientific cooperation between universities in different countries. In this context, this paper explores a scientific cooperation project developed by two universities in Brazil and Spain: the Universidade Estadual de Campinas (UNICAMP) and the Universitat Politecnica de Valencia (UPV), relating to the field of Computer-Assisted Learning (CAL). First of all, the interna…

Difficulties in Teaching Modelling: A French-Spanish Exploration

2017

An exploratory research study based on an online questionnaire in order to better understand difficulties encountered in teaching of mathematical modelling in France and Spain is presented. This questionnaire takes into account biographical variables, mathematics and modelling conceptions of pre-service teachers, teachers, researchers and education inspectors, from primary to tertiary education. Regarding difficulties, heterogeneous conceptions are revealed, and the analysis constructs four clusters, from positive and confident conceptions to negative and lacking confidence. In some cases, the roles of some biographical variables are indicated such as country, age, gender or school level th…

Effects of caspase inhibitors (z-VAD-fmk, z-VDVAD-fmk) on Nile Red fluorescence pattern in 7-ketocholesterol-treated cells: Investigation by flow cyt…

2007

Background: The 7-ketocholesterol (7KC)-induced cell death has some characteristics of apoptosis and is associated with polar lipid accumulation. So, we investigated the effects of the broad-spectrum caspase inhibitor z-VAD-fmk and of the caspase-2 inhibitor z-VDVAD-fmk on lipid profile evaluated by staining with Nile Red (NR). Methods: The 7KC-treated human monocytic U937 cells were cultured in the absence or in the presence of the caspase inhibitors z-VAD-fmk or z-VDVAD-fmk. When staining with NR is performed, neutral and polar lipids have yellow and orange/red emission, respectively, and fluorescence was then analyzed by flow cytometry (FCM) and by confocal laser scanning microscopy (CLS…

Moderate hypofractionated helical tomotherapy for localized prostate cancer: preliminary report of an observational prospective study.

2019

Objective: To report preliminary findings of a phase II study exploring the clinical outcomes of moderate hypofractionated radiotherapy performed with helical tomotherapy (HT) using computed tomography–magnetic resonance imaging–based planning for localized prostate cancer. Methods: The phase II prospective study received ethics approval from our institutional ethics committee. A dose of 60 Gy/20 fractions for low–intermediate risk prostate cancer by means of HT was explored. Primary endpoints of the study were acute and late gastrointestinal (GI) and genitourinary (GU) toxicities. Secondary endpoints were quality of life and biochemical-free survival. Results: A total of 35 patients were i…
