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 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 study examines 4 different methods to reduce dental bioaerosol spread in orthodontic procedures.
The Norwegian Sickness Absence Clinic (NSAC) is a publicly funded specialist outpatient health service, which is uniquely available for the work force. The overall aim of the NSAC is prevention of sickness absence, promote return to work (RTW) among those on sickness absence and prevent long term disability benefit dependency. In addition to being a health service, the NSAC has a focus on work and functional recovery, including also non-health related factors. Patients can be referred by general practitioners for mental health problems and musculoskeletal problems. The NSAC has a lower threshold for severity than specialist health services generally, and in particular for mental health problems. The efficacy of this service is unknown. The NSAC Efficacy Study is a randomized controlled multicentre trial which aims to assess the effect of the NSAC service. "Helse i Arbeid" is the Norwegian name for NSAC, and the Norwegian abbreviation is "HiA". The Norwegian study name is HIANOR. The NSAC Efficacy Study involves five different NSACs across northern Norway, and will recruit 2500 patients, randomized to in equal proportions to three treatment arms: 1. NSAC - rapid: treatment at the NSAC at- or within 4 weeks 2. NSAC - ordinary: treatment at the NSAC after 10-14 weeks 3. NSAC - active control: monodisciplinary examination at the NSAC close to diagnosis-specific deadline for examination as suggested by guidelines (8-26 weeks, the majority at the end of this interval) The overall aim is to assess the effect of the NSAC service, with the hypothesis that the NSAC service is superior to what resembles treatment as usual (TAU) for outcomes such as return to work or improved health (waiting list control). Many of the diagnoses or problems for which patients are referred to the NSACs naturally improve regardless of health interventions, and - as of date - no research has been conducted to assess the efficacy of the service.
Introduction: Sarcomas are rare tumors of connective tissue. The exact overall incidence of sarcomas is unknown due to diagnostic difficulties and the various histological subtypes (over 80 subtypes). However, the apparent increasing incidence of sarcomas suggests environmental causes such as pesticides. Except for some specific factors (i.e. ionizing radiation, vinyl chloride, dioxin, and genetic predispositions) the scientific knowledge on the aetiology of sarcomas is sparse and inconsistent. France is a particularly appropriate country to set up a study investigating the causes of sarcoma occurrence due to the French organization in treatment and care of sarcoma patients, which is highly structured and revolved around national expert networks. The main objective of the ETIOSARC project is to study the role of lifestyle, environmental and occupational factors in the occurrence of sarcomas among adults from a multicentric population-based case-control study. Methods and analysis: Cases will be all incident cases (older than 18 years old) identified in 15 districts of France covered by a cancer registry and/or a reference center in sarcoma's patient care over a three-year period with an inclusion start date ranging from the 1st October 2018 to the 1st January 2020 and histologically confirmed by a second review of the diagnosis. Two controls will be individually-matched by sex, age (5-years group), and districts of residence and randomly selected from electoral list. A standardized questionnaire will be administered by a trained interviewer in order to gather information about occupational and residential history, demographic and socioeconomic characteristics and lifestyle factors. At the end of the interview, a saliva sample will be systematically proposed. This study will permit to validate or not already suspected risk factors for sarcomas such as phenoxyherbicides, chlorophenol and to generate new hypothesis to increase our understanding about the genetic and environmental contributions in the carcinogenicity process.
detection of DNA damage due to occupational exposure to low dose ionizing radiation using comet assay technique and genotyping of certain DNA repair genes to detect inherited polymorphism.
The aim of the study is to evaluate the diagnostic accuracy of an instrument (semi-structured interview) called Workload Analysis Instrument (WAI) (Análisis de Carga de Trabajo ACT), in detecting the presence of occupational risk in patients presenting an upper-limb musculoskeletal disorder. The test instrument was developed by Asociación Chilena de Seguridad (ACHS). This instrument will be applied to the worker when he or she visits the ACHS health care facility. The test administration is performed by an ergonomics specialist previously trained in WAI. WAI is the index test and the gold standard will be the Estudio de Puesto de Trabajo (EPT) resolution. The hypothesis of the study is that WAI is able to correctly label the occupational origin (rule in or rule out) of an upper-limb musculoskeletal disorder. Sensitivity, specificity and positive predictive value will be established.
