The Strange Case of the Protective Perimeter: Liberties and Claims to Non-Interference
2011
In this paper I aim at pointing out some difficulties raised by the so-called thesis of the protective perimeter of liberties (ToPP), that is: the thesis according to which: neither a privilege necessarily involves a claim to non-interference, nor a claim to non-interference necessarily presupposes a privilege. As to the first aspect of the thesis, I argue that it relies on a misleading concept of ‘interference with a liberty’, which surfaces in the examples to which the thesis is made applicable. As to the second aspect of the thesis, I argue that the idea of someone having a claim to be unimpeded in wronging another person is a misleading description of the situation taken into considerat…
Efficacy of protection by latex gloves during orthodontic therapy.
2000
The wearing of gloves during orthodontic or dental treatment is generally indicated for reasons of hygiene and protection against infection. This study was aimed at determining the extent and localization of perforations caused by the various orthodontic treatment techniques and interrupting the infection barrier. The impermeability was tested by means of a water retention test according to European standard EN 455, Part 1, performed on 1600 Centramed (Centramed, Koblenz), Tekmedic and SafeEx non-sterile disposable latex gloves (both by Safe Med, Switzerland) and Safe Gan latex gloves with an additional acrylate coating (also by Safe Med). The perforation rate in unused gloves was between 0…
Study protocol for an online questionnaire survey on symptoms/signs, protective measures, level of awareness and perception regarding covid-19 outbre…
2020
The Centres for Disease Control and Prevention and the World Health Organization have developed preparedness and prevention checklists for healthcare professionals regarding the containment of COVID-19. The aim of the present protocol is to evaluate the impact of the COVID-19 outbreak among dentists in different countries where various prevalence of the epidemic has been reported. Several research groups around the world were contacted by the central management team. The online anonymous survey will be conducted on a convenience sample of dentists working both in national health systems and in private or public clinics. In each country/area, a high (~5–20%) proportion of dentists working th…

Internal exposure of firefighting instructors to polycyclic aromatic hydrocarbons (PAH) during live fire training
2019
Firefighting instructors in live fire training are inevitably exposed to emissions containing, carcinogenic PAH. The study investigated PAH uptake in a group of firefighting instructors during short-term exposure in live fire training by urinary biomonitoring. Six firefighting instructors (non-smokers) completed five 2 h-training sessions each in a carbonaceous-fired simulation unit using self-containing breathing apparatuses (SCBA). Complying with a minimum time interval of six days between the individual training sessions, the participants provided urine samples before and immediately after, as well as 1, 3, 6, 9, 11, and 18 h after each training session. Samples were analyzed for 10 mono…
P4613Long-term impact of postnatal nutritional programming on cardiac sensitivity to ischemia-reperfusion injury in vivo and on cardio-protective pat…
2019
Abstract Introduction Nutritional disturbances during the postnatal period may be responsible for a predisposition, or “programming”, to increased cardio-metabolic risk and to a progressive alteration of left ventricular contractility in adulthood. This nutritional perinatal programming may also lead to an alteration of cellular pathways involved in cardiac protection, such as the specific RISK and SAFE pathways, highlighted during pre- and post-ischemic conditioning or those of sirtuins (SIRT), histone deacetylases involved in the regulation of essential biological process. Purpose Our aim was to evaluate in mice the impact of postnatal overfeeding (PNOF) on cardiac sensitivity to ischemia…
Tidal Volume Estimation during Helmet Noninvasive Ventilation: an Experimental Feasibility Study
2019
AbstractWe performed a bench (BS) and human (HS) study to test the hypothesis that estimation of tidal volume (VT) during noninvasive helmet pressure support ventilation (nHPSV) would be possible using a turbine driven ventilator (TDV) coupled with an intentional leak single-limb vented circuit. During the BS a mannequin was connected to a lung simulator (LS) and at different conditions of respiratory mechanics, positive end expiratory pressure (PEEP) levels and leaks (30, 50 and 80 L/min). All differences were within the 95% limits of agreement (LoA) in all conditions in the Bland-Altman plot. The overall bias (difference between VT measured by TDV and LS) was 35 ml (95% LoA 10 to 57 ml), …
Application of a polymer-based photocatalytic coating for the protection of limestone stones substrates: an exposure study
2022
In the last decades there have been several studies on cultural heritage regarding the performance of protective and consolidating coatings for the prevention of decay. A coating must have several characteristics such as: efficiency, breathability, and must be durable and reversible. In this research work we tried to verify the performance of a commercial protective product such as Fosbuild FBLE 200, which is composed of a TiO2 nanopowder dispersed in an aqueous solution of an acrylic polymer. This product, which exhibits depolluting, antimicrobial, water-repellent and self-cleaning characteristics, has been applied on different lithotypes such as: Carrara marble, Noto and Comiso stone and …
Barnet som aktør og kunnskapsbærer – en utfordring for barnevernets profesjonelle ekspertise
2010
Author's version of an article published in the journal: Norges Barnevern. Also available from the publisher at: http://www.idunn.no/ts/tnb/2010/03/art04 During recent years, it has become more and more common to consider children as competent participants in their own lives, also in the child protective services. This agrees with the UN Convention on the Rights of the Child and more recent research on children and childhood. That is to say that the child is seen as the expert on his own life, at the same time as the child protective services with their professional expertise have competence to say what is best for children. What does this imply and how can we understand the relation betwee…
Head and neck cancer surgery during the COVID-19 pandemic: An international, multicenter, observational cohort study
2020
Background The aims of this study were to provide data on the safety of head and neck cancer surgery currently being undertaken during the coronavirus disease 2019 (COVID-19) pandemic. Methods This international, observational cohort study comprised 1137 consecutive patients with head and neck cancer undergoing primary surgery with curative intent in 26 countries. Factors associated with severe pulmonary complications in COVID-19-positive patients and infections in the surgical team were determined by univariate analysis. Results Among the 1137 patients, the commonest sites were the oral cavity (38%) and the thyroid (21%). For oropharynx and larynx tumors, nonsurgical therapy was favored in…
