Filter by:The biomonitoring study aims to evaluate genotoxic damage and other parameters of exposure in different occupational exposed populations that work directly with different plastics.
Work-related musculoskeletal disorders (WRMSD), multifactorial diseases that affect the working population and which can be caused and/or aggravated by work and occupational exposures, continue to Prevention interventions for these pathologies have recently made use of technological advancement, which has made external devices available for the assistance of human activities, i.e. occupational exoskeletons (EXO). Despite the suggestive potential inherent in these devices, their actual adoption in the working and industrial world is still uncertain due to the absence of evidence on their effectiveness, safety of use and appropriateness. The use of EXO increases the user's ability to carry out manual tasks in different work contexts, lightening the perception of physical effort and promoting higher levels of safety, as well as promoting better performance. These advantages derive from the effective reduction in muscle activity that the use of EXO allows. A certain variability in the effects was referred to factors such as the type of work task, the type of exoskeleton adopted, the duration of use of the exoskeleton, as well as to individual differences and different behaviours at work. The field studies, carried out so far in the automotive, manufacturing, logistics and agriculture sectors, are fundamental to understanding the actual effectiveness, practicality, safety and acceptance of EXO by the user. This project contributes to the expansion of knowledge relating to the prevention of WRMSD through EXO, applying wearable sensors in a real working situation such as the textile sector, in which the female gender constitutes the majority of the workforce.
The study aims: - To identify the main occupational health hazards to which the superphosphate fertilizer industry workers are exposed. - To identify the respiratory and auditory health effects of these hazards and associated risk factors among those workers. - To clarify the knowledge, attitudes, and practices of workers towards the chemical health hazards affecting the respiratory system (dust and hazardous gases). - To assess the effect of health education program on workers' knowledge, attitudes, and practices towards these hazards and the use of personal protective equipment (PPE).
The goal of this clinical trial is to investigate the effects of Intelligent Physical Exercise Training (IPET) and ergonomic recommendations on musculoskeletal pain among abdominal and pelvic surgeons. The main question it aims to answer is: • Is IPET superior to ergonomic recommendations in rehabilitating or preventing musculoskeletal pain? 12 weeks ahead of trial start, all participants will be familiarized with ergonomic principles in the operating room. In the 20-week trial, the control group is asked to resume practicing and applying the ergonomic principles when they operate. In addition to applying the ergonomic principles, the Intervention group will be asked to perform 50 min. per week of individually tailored physical exercise training. The program is delivered via an application (app).
Some military personnel who have been exposed to burn pit emissions, desert dust, and other airborne hazards experience new respiratory symptoms after deployment. The goal of this clinical trial is to learn about exercise in veterans with new respiratory symptoms after deployment to Southwest Asia. The main questions it aims to answer are: 1. Do veterans with new respiratory symptoms after deployment have heart or lung abnormalities that contribute to difficulty exercising? 2. Does high-intensity interval training (HIIT) improve fitness and symptoms? Study participants will complete the following: 1. Study Visits 1A and 1B: Exercise test (VO2max test), echocardiogram (heart ultrasound), blood tests, questionnaires 2. Exercise program: 12 weeks of 3x/week supervised HIIT on upright stationary bicycle (~40 minutes each) and 3x/week home aerobic exercise (45 minutes each) 3. Study Visits 2A and 2B: Exercise test (VO2max test), echocardiogram (heart ultrasound), blood tests, questionnaires
The overall aim of this study is to investigate how work with physical demands affects the physical capacity, work ability, labor market affiliation, pain and self-reported health in the oldest group of workers. Following research questions are to be answered: 1. How high physical work demands affects muscle strength in 55-70-year-old workers and how obesity in combination with high physical work exposure influences muscle strength, work ability, cardiac function, and self-reported health? 2. Which parameters are important for work ability and how does the exposure of high physical workload affect the work ability over time in 55-70-year-old workers? 3. By exploring the underlying mechanism of pain among 55+ year old workers, how is pain associated with work ability, BMI and physical capacity?
Americans who work outdoors are exposed to an extreme amount of solar ultraviolet radiation over a lifetime that substantially increases their risk for developing skin cancer. In Phase I, the feasibility of a virtual learning environment (VLE) for distributing the effective Sun Safe Workplaces (SSW) intervention to American employers will be established with input from senior managers and Hispanic and African American outdoor workers and development and evaluation of a prototype of the SSW Works VLE. In Phase II, the full SSW Works will be produced and tested for effectiveness at improving outdoor workers' sun protection in a randomized trial enrolling employers nationwide.
Methoxyflurane is an anesthetic gas and at low doses has shown to help with pain. Methoxyflurane was approved in Canada in 2018. Low-dose methoxyflurane is self-administered by patients via a handheld inhaler. Exhaled methoxyflurane is captured by an activated carbon (AC) chamber fitted to the inhaler in order to minimize environmental and occupational exposure. It provides rapid (<1 minute), short-term (30-45 minutes) pain relief within six to ten inhalations and has been shown to be effective and safe in emergency care and for minor surgical, radiological, and dental procedures. The current dosing recommendation is 3 ml bottle. However, the frequency at which methoxyflurane treatment can be safely used by paramedics is not established. From the product monograph, a patient's maximum daily dose of 6 mLs and weekly 15 mLs of methoxyflurane. The treatment course of methoxyflurane for patients should not be repeated at an interval of less than 3 months. Despite the activated carbon chamber to capture the exhaled methoxyflurane, when paramedics are supervising patients receiving inhaled analgesia within a confined area (like the back of an ambulance), it is possible that a paramedic may experience intermittent exposure to methoxyflurane vapour. Multiple use of the methoxyflurane Inhaler, with or without the AC chamber, creates additional risk. Elevation of liver enzymes, blood urea nitrogen, and serum uric acid, have been reported in healthcare professionals regularly exposed to methoxyflurane inhalational products. 8 A formal limit regarding levels of occupational exposure to methoxyflurane has not been established. The risk of occupational exposure of methoxyflurane will be evaluated in a controlled laboratory setting, recruiting 30 health, screened (history and blood work) volunteers to participate in the back of an ambulance which meets the Ontario Ministry of Health Standards. The participants will consent and follow a protocol while active samplers are placed in the rear of the ambulance to capture the off-gassing of the methoxyflurane. This will inform the risk of occupational exposure of methoxyflurane to paramedics, as well as, hoping to inform the risk of multiple administrations by paramedics to different patients during a single shift, to ensure a medical directive can be created to support patient care and evaluate and support paramedic safety.
An experimental study, which will aim to compare changes of trunk mechanical properties and neuromuscular control following spinal flexion exposure in crane operators and control subjects.
This study established a sub-cohort of emergency medical workers, for the development of health care and disease prevention solution, by identifying epidemiological characteristics and factors related to occupational exposure. Each life-log or environment-log data will be collected by wearable device (e.g. smart-watch) and IoT (e.g. Edge-box). From collected data, relationship between health risks and occupational exposure of emergency medical workers will be determined.
