Alors que les nanotechnologies émergentes ouvrent des voies prometteuses dans plusieurs secteurs d’activité, des études suggèrent que les nanoparticules (NP) qu’elles génèrent pourraient avoir des effets négatifs, notamment sur la santé et sur l’environnement. Celles-ci peuvent être générées lors de la fabrication, de la manutention et de l’assemblage de pièces métalliques ordinaires et de celles à base de nanomatériaux. D’autres activités quotidiennes, telles que le freinage des automobiles, peuvent aussi produire des NP. Il est donc urgent de trouver des moyens de contrôler ces risques. Cependant, les techniques et méthodes usuelles …

Avec le vieillissement de la population, la demande de soins palliatifs (SP) de fin de vie est croissante et les services de santé s’organisent. Au Québec, les SP de fin de vie sont surtout intégrés aux soins curatifs et on retrouve peu d’unités de SP spécialisées. Ces soins s'incorporent alors aux soins à domicile ou à ceux dispensés dans les unités de soins spécialisés en centre hospitalier, comme l’oncologie et les soins critiques. Les infirmières y jouent un rôle majeur. Selon ce choix organisationnel, les infirmières vivent un contexte de travail …

Une nouvelle technologie d’alarmes de recul de véhicule lourd a fait récemment son apparition sur le marché. Cette technologie, basée sur l’utilisation d’un signal large-bande (bruit de type « pschitt- pschitt ») serait, selon le manufacturier, plus sécuritaire pour les travailleurs tout en causant moins de nuisance environnementale que l’alarme tonale conventionnelle (bruit de type « beep-beep »). Il demeurait toutefois difficile de se prononcer sur la supériorité de cette technologie puisqu’il existe très peu d’études scientifiques indépendantes et rigoureuses portant sur celle-ci.

Cette étude visait à comparer la nouvelle technologie …

Management Commitment In Occupational Safety And Health As It Relates To Federal Agency Programs, John Sterling Crumbley

Online Theses and Dissertations

By asking the question "in what areas of 29 CFR 1960 are Federal Agency Program leaders deficient with regard to committing to their OSH programs;" this research project explored the commitment issue(s) Federal Agency Leaders encounter while administering their OSH programs. Since the inception of the Occupational Safety and Health Administration (OSHA) and their revelation that management commitment is critical to OSH program success, senior leadership has struggled exercising this concept. Many safety professionals, such as those cited in the Literature Review of this study have also examined this issue. However, while many articles and peer-reviewed journals indicate there is …

Compliance Of Scba Training In The Lexington Fire Department, Jordan Peter Saas

Online Theses and Dissertations

From 2010 through 2013, an average of 90 firefighters died in the line of duty each year (USFA, 2014). Firefighters who are off-duty continue to die as well, however, it is extremely difficult to determine whether their deaths are a result of on-duty-related exposures or not. Medical and field research has consistently found associations between smoke inhalation and acute and chronic illnesses that highlight the dangers of on-duty exposure to smoke. This study investigates the early removal of the SCBA by firefighters in one fire department while operating at fire incidents. The findings indicate that firefighters are mostly aware of …

Dr. Who?: The Science And Culture Of Medical Wear Design, Patricia Duignan

Theses and Dissertations

The multi-million-dollar medical uniform industry has not utilized advancements in garment and textile technology that could positively impact the protection of healthcare professionals and patients. In most cases the uniforms meet basic requirements – they clothe the professional in a recognizable way. Little innovation in design, function and performance, has been applied to these garments. This is particularly evident in the case of the stereotypical white lab coat worn by many physicians, despite evidence indicating that these lab coats may carry contamination and play a role in the spread of deadly bacteria. Healthcare Associated Infections (HAIs) are among the most …

This research seeks to define minimum OSH baccalaureate graduate core competencies across all programs by asking: What would employers look for in a portfolio to demonstrate competence in a new OSH graduate? Professional members of the American Society of Safety Engineers (ASSE) participated as subject matter experts in an anonymous online survey to provide framing data. The ASSE Educational Standards …

Physical Fitness Characteristics Of An Active Firefighter Population Serving An Urban Area, Michael R. Antolini

Theses and Dissertations (Comprehensive)

Firefighters require a high level of physical fitness in order to meet the demands of their profession. While physical fitness testing is required to join the department, firefighters are not subject to further formal exercise testing throughout the duration of their careers. Active, career firefighters were tested on a variety of physical fitness measures related to body composition, strength, power, and endurance over three testing sessions. 49 firefighters (40.5 ± 8.3 yr, 89.5 ± 13.0 kg, 27.8 ± 3.6 kg/m2) were found to have a resting heart rate of 57.7 ± 8.2 bpm, blood pressure of 121.5 ± 11.9/71.5 ± …

An Investigation Into Dust, Gases And Vapours Expulsed During The Oxidation Of Pyritic Black Shale, And Their Potential For Impacting On Employee Health, Tristan Lynn

Theses: Doctorates and Masters

Pyritic black shale (PBS) is occasionally extracted as a waste product of iron ore mining in the Pilbara region of Western Australia. Mineralogical studies such as Brocks, Summons, Buick, and Logan (2003) of the PBS located at Mount Tom Price Operations have established that PBS can contain elevated concentrations of pyrite, carbon, bitumens, polyaromatic hydrocarbons and volatile organic compounds (VOCs). The natural oxidative weathering of PBS can cause exothermic reactions leading to the shale reaching temperatures that cause the expulsion of toxic gases such as hydrogen sulphide, sulphur dioxide, methane and carbon monoxide.

The Escherichia coli sequence type 131 (ST131) clone is notorious for extraintestinal infections, fluoroquinolone resistance, and extended-spectrum beta-lactamase (ESBL) production, attributable to a CTX-M-15-encoding mobile element. Here, we applied pulsed-field gel electrophoresis (PFGE) and whole-genome sequencing to reconstruct the evolutionary history of the ST131 clone. PFGE-based cluster analyses suggested that both fluoroquinolone resistance and ESBL production had been acquired by multiple ST131 sublineages through independent genetic events. In contrast, the more robust whole-genome-sequence-based phylogenomic analysis revealed that fluoroquinolone resistance was confined almost entirely to a single, rapidly expanding ST131 subclone, designated H30-R. Strikingly, 91% of the CTX-M-15-producing isolates also …

Nanoparticules Synthétiques : Gestion Adaptative Des Risques À La Santé Et À La Sécurité Des Travailleurs, Julien Fatisson, Stéphane Hallé, Sylvie Nadeau, Claude Viau, Michel Camus, Barthélémy Ateme-Nguema, Yves Cloutier

Rapports de recherche scientifique

De plus en plus les nanotechnologies suscitent un grand intérêt autant sur le plan industriel que médical. Cependant, la production de nanoparticules synthétiques (NPS) continue de croître alors que les impacts sanitaires et environnementaux n’ont pas tous été évalués, amenant ainsi de nouveaux problèmes. Consécutivement à l’expansion du marché des nanotechnologies, le nombre de travailleurs exposés continue d’augmenter. Bien qu’aucun consensus mondial ne se dégage en ce qui a trait à une définition et une règlementation clairement adaptées aux NPS, le besoin de protéger les travailleurs reste capital et passe par une gestion des risques adaptée.

Work Stress Reactivity And Health Outcomes: A Study Of Nurses, Laurie Marie Jacobs

Dissertations and Theses

Negative events encountered in daily life influence individual well-being. Individuals vary in their reactivity to these events, the extent to which they are behaviorally, physiologically, and psychologically influenced by them (Almeida, 2005; Neupert, Almeida, & Charles, 2007). Reactivity to events in the form of changes in health behavior could represent either an attempt at coping (Cooper, Frone, Russell, & Mudar, 1995) or a stressor-related failure of self-control (Muraven & Baumeister, 2000). Such changes in behavior could have later effects on health.

Although a great deal of attention has been paid to both the immediate and long-term effects of stressors on …

Molecular Epidemiology Of Escherichia Coli Sequence Type 131 And Its H30 And H30-Rx Subclones Among Extended-Spectrum-Β-Lactamase-Positive And -Negative E.

Price, James R. Johnson

Environmental and Occupational Health Faculty Publications

We assessed Escherichia coli ST131 and its H30 and H30-Rx subclones for virulence genes, antimicrobial resistance, and extended-spectrum beta-lactamase (ESBL) type. Although both subclones were associated with ESBL production, H30-Rx isolates had higher resistance scores and were associated specifically with CTX-M-15. Three virulence genes (iha, sat, and iutA) were more prevalent among H30 than non-H30 ST131 isolates. Thus, the H30 and H30-Rx subclones are more antimicrobial resistant and have virulence profiles that are distinct from those of non-H30 ST131 isolates.
