Development Of The Resident Wellness Scale For Measuring Resident Wellness, R. Brent Stansfield, Dan Giang, Tsveti Markova

Journal of Patient-Centered Research and Reviews

Purpose: Graduate medical education programs have a responsibility to monitor resident wellness. Residents are at risk of burnout, depression, and suicide. Burnout and depression are associated with poor patient care. Many existing tools measure burnout, depression, and general human well-being, but resident wellness is a distinct construct. We aimed to develop an instrument to measure resident wellness directly.

Methods: An expert panel from two purposefully different graduate medical education institutions generated a behavior- and experience-based model of resident wellness. The panel and resident leaders from both institutions generated 92 items, which were tested alongside anchor scales measuring burnout, depression, personality, …

The unique physicochemical properties of multi-walled carbon nanotubes (MWCNT) have led to many industrial applications. Due to their low density and small size, MWCNT are easily aerosolized in the workplace making respiratory exposures likely in workers. The International Agency for Research on Cancer designated the pristine Mitsui-7 MWCNT (MWCNT-7) as a Group 2B carcinogen, but there was insufficient data to classify all other MWCNT. Previously, MWCNT exposed to high temperature (MWCNT-HT) or synthesized with nitrogen (MWCNT-ND) have been found to elicit attenuated toxicity; however, their genotoxic and carcinogenic potential are not known. Our aim was to measure the genotoxicity of …

Multi-Walled Carbon Nanotube-Induced Gene Expression Biomarkers For Medical And Occupational Surveillance, Brandi N. Snyder-Talkington, Chunlin Dong, Salvi Singh, Rebecca Raese, Yong Qian, Dale W. Porter, Michael G. Wolfarth, Nancy L. Guo

Faculty & Staff Scholarship

As the demand for multi-walled carbon nanotube (MWCNT) incorporation into industrial and biomedical applications increases, so does the potential for unintentional pulmonary MWCNT exposure, particularly among workers during manufacturing. Pulmonary exposure to MWCNTs raises the potential for development of lung inflammation, fibrosis, and cancer among those exposed; however, there are currently no effective biomarkers for detecting lung fibrosis or predicting the risk of lung cancer resulting from MWCNT exposure. To uncover potential mRNAs and miRNAs that could be used as markers of exposure, this study compared in vivo mRNA and miRNA expression in lung tissue and blood of mice exposed …

Rapports de recherche scientifique

Le nombre total d’arthroplasties du genou réalisées entre 2008 et 2009 a connu une augmentation significative par rapport à la décennie précédente, représentant une augmentation de 139 %. Cette augmentation est en partie attribuable au fait que la chirurgie procure une meilleure qualité de vie aux travailleurs vieillissants qui désirent demeurer actifs sur le marché du travail. De plus, l’innovation a amélioré la longévité des types de prothèses, de sorte que la chirurgie peut être proposée plus tôt dans la vie. Cet accroissement étant relativement récent, il existe peu de données dans la littérature permettant de situer la trajectoire de …

Collaborative Robotics: Assessment Of Safety Functions And Feedback From Workers, Users And Integrators In Quebec, Sabrina Jocelyn, Damien Burlet-Vienney, Laurent Giraud, Adel Sghaier

Rapports de recherche scientifique

Depuis 2010, l’industrie utilise un nouveau genre de robot capable d’interagir avec les travailleurs en production ou simplement de partager le même espace de travail. On les appelle « robots collaboratifs » ou cobots. Le cobot se distingue des robots conventionnels par l’interaction entre la machine et le travailleur; il accompagne ce dernier, l’assiste ou l’aide à réaliser des tâches. Toutefois, ce changement technologique fait apparaître de nouveaux risques surtout en production : risques de collisions (puisque l’humain peut être en contact avec le cobot), risques de troubles musculosquelettiques (TMS) (même si le cobot est conçu pour les éviter, il …

The Impact Of Shift Work On Health And Wellbeing, Stephanie M. Gagelin

Physician Assistant Scholarly Project Posters

• Many of today’s industries require workers to perform shift work (typically during 1600-0700). If workers are awake during this time period, circadian misalignment occurs. This scholarly project uses research studies and meta- analyses to provide information about increased health risks associated with circadian misalignment, focusing on the categories of glucose metabolism, cardiovascular system, carcinogenesis, and mental health and acuity.

• Shift work has been found to increase BMI and waist circumference of employees, as well as increase blood glucose levels to “prediabetic” levels in previously euglycemic individuals.

• Shift work has been proven to increase high-sensitivity C-reactive protein (hs-CRP), …

Filtration Of Nanoparticles Applied In General Ventilation, Clothilde Brochot, Pooya Abdolghader, Fariborz Haghighat, Ali Bahloul

Études primaires

Nanoparticles (NPs) are particles with a diameter less than or equal to 100 nm. Because of their size, they pose a major challenge to workers’ health and safety. General ventilation is one of the solutions in order to minimize both occupational and general exposure.

In North America, ventilation filters are tested according to ANSI/ASHRAE Standard 52.2 and rated according to their efficiency results as a function of particle diameter. The most penetrating particle size (MPPS) is commonly accepted as being 300 nm, but it no longer represents the worst-case scenario in terms of particle diameter and filter penetration.

The purpose …

Procedure To Measure The Penetration Of One Mechanical Filter For Nanoparticles: Validation By Comparison, Pooya Abdolghader, Clothilde Brochot, Fariborz Haghighat, Ali Bahloul

Études primaires

Nanoparticles (NPs) are particles of less than or equal to 100 nm in diameter. Due to their size, they have a significant effect on health and safety of people. Capture of these NPs in general ventilation systems by filters remains one of the most widely used means of protection due to its relative simplicity of implementation and its effectiveness for capturing various size of particles. In North America, filters used in general ventilation systems are tested by the ANSI/ASHRAE Standard 52.2 and are graded according to their efficiency, which is a function of particle diameter. However, the current standard limits …

Études primaires

Exposure to occupational carcinogens is often overlooked as a contributor to the burden of cancer. To estimate the proportion of cancer cases attributable to occupational exposure in Canada in 2011, exposure prevalence and levels of 44 carcinogens were informed by data from the Canadian carcinogen exposure surveillance project (CAREX Canada). These were used with Canadian Census (between 1961 and 2011) and Labour Force Survey (annual surveys between 1976 and 2013) data to estimate the number of workers ever exposed to occupational carcinogens. Risk estimates of the association between each carcinogen and cancer site were selected mainly from published literature reviews. …

Human Performance In Manufacturing Tasks: Optimization And Assessment Of Required Workload And Capabilities, Maria Chiara Leva, Lorenzo Comberti, Micaela Demichela, Alberto Caimo

This paper discusses some examples where human performance and or human error prediction was achieved by using a modified version of the Rasch model(1980), where the probability of a specified outcome is modelled as a logistic function of the difference between the person capacity and item difficulty. The model needs to be modified to take into account an outcome that may not be dichotomous and o take into account the interaction between two macro factors: (a) Task complexity: that summarises all factors contributing to physical and mental workload requirements for execution of a given operative task & (b) Human capability: …

Stress State Analysis And Tensile-Shear Fracture Criterion In Combined Puncture And Cutting Of Soft Materials, Ennouri Triki, Chantal Gauvin

Études primaires

The mechanics of the combined puncture and cutting of protective materials by a pointed blade are studied theoretically and experimentally, by means of stress state analysis. Through analysis of the stresses occurring during the puncture cutting of a variety of neoprene and nitrile rubber membranes by pointed blades with different cutting-edge angles, a force state of pushing/shear-dependent loading is formulated and discussed. By considering this combined loading as an asymmetric fracture, two equations—for pushing force component and shear force component—are then derived from the stress intensity factors. From this stress analysis, a model based on fracture mechanics theory is developed …

Methods:

In this experimental and comparative study, lumbar stiffness, a surrogate measure of lumbar stability, was estimated in 25 healthy individuals during 7 trunk perturbation conditions: (1) control, (2) ADIM, (3) bracing …

A Transfer Matrix Model Of The Iec 60318-4 Ear Simulator: Application To The Simulation Of Earplug Insertion Loss, Yu Luan, Franck Sgard, Simon Benacchio, Hugues Nélisse, Olivier Doutres

Études primaires

The IEC 60318-4 ear simulator is used to measure the insertion loss (IL) of earplugs in the ear canal of an acoustical test fixture (ATF) and is designed to represent an average acoustic impedance (in a reference plane) of the human ear. The ear simulator is usually modeled using a lumped parameter model (LPM) which has frequency limitations and inadequately accounts for the thermo-viscous effects in the simulator. The simulator numerical models that can better deal with the thermo-viscous phenomena often lack essential geometric details. Most related studies also suffer from the lack of experimental validation of the models. Therefore, …
