Filter by: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.
Due to demographic changes across Europe there are strong political interests in maintaining the labour force by prolonging working life, i.e. increasing retirement age. The present study investigates push and stay mechanisms for labor market attachment among older (+50 yrs) workers or people who have recently retired.
Exposure to sedentary work is an occupational hazard with significant health and safety consequences. Sedentary behavior is an independent predictor of heart disease, diabetes, early mortality, and accounts for the majority of the increase in obesity in the US. Prolonged sitting, common in modern sedentary work environments, contributes to increases in musculoskeletal pain, injuries, and detrimental changes in physiological functioning. Call center employees, who are among the most sedentary workers in the US, area priority population for Total Worker Health interventions. This project is designed to substantially improve health, safety, and well-being in call center employees, including physiological outcomes that contribute to chronic diseases.The study tests whether a Total Worker Health oriented intervention is more effective than usual practices for increasing the utilization of health and safety resources and improving worker health and safety. Study results will have implications for over 30 million sedentary workers in the US.
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.
In this intervention study, the investigators engage Vietnamese American nail salon owners to train workers within their salons on how to reduce workplace chemical exposures. The long-term goal of the study is to reduce toxic chemical exposures in nail salons and promote worker health and safety in this vulnerable worker population.
In a cluster randomized design it will be investigated whether teaching local leaders how to implement active pregnancy policy results in less sickness absence among their pregnant employees. Further it will be investigated to what extent Active pregnancy policy is implemented at the departments and whether it results in higher sense of security and wellbeing among the pregnant employee. Finally the cost and benefits of the intervention will be analyzed.
Radiation now becomes a dreadful effect as its outcomes are tremendous to be expected. As a result, anesthetists become an inevitable target to the radiation exposure since they have to monitor patients closely during the operation. Unfortunately, radiation may not have an immediate sequelae, but an accumulation of adverse effects. These sequelae happen by means of direct exposure and reflection. The reflected rays is inversely proportional to the distance between the origin and the target. Practically, the radiation source can be protected by individual cover and glass shield. Siriraj hospital is a tertiary, general university hospital with 2,200 beds. Annually, an Endoscopy centre has over 700 patients undergoing endoscopic retrograde cholangio pancreaticography (ERCP). Normally, fluoroscopy for pancreatic and biliary ducts visualisation is needed under anesthesia. Though the procedure is operated in a well-equipped, radiating-protection room; many medical personnel including 1-2 endoscopists, 2 scrub nurses, 1-2 anesthetists and 1 x-ray man, still have a chance of irradiation. During ERCP, all medical personnel particularly anesthetists are rinsed by radiation from here and there. Though they always wear lead aprons and collar shields to protect themselves from the rays, they are normally in the position - less than 1 meter - close to the fluoroscopy. Due to the advancement in technology, anesthetists can remotely monitor patients during the surgical procedure. This might cause a lesser effect of ray upon them. As a result, whether or not the positioning of anesthesia personnel relating to the distance of x-ray source would help to alleviate the effect of radiation exposure.
Anisakidae frequently infect fish species that are commonly eaten by humans. Some of them are recognized as zoonotic agents, and have a high impact on human health. Infestation results from the ingestion of living larvae from contaminated fishes. It can be asymptomatic or symptomatic, resulting in acute gastric, acute intestinal or chronic forms. Allergic manifestations are frequently encountered in gastric forms, but isolated allergic symptoms can occur after ingestion of Anisakidae antigens in raw or cooked fish. Cutaneous contact or Anisakis allergen inhalation have also been reported to induce allergy/anaphylactic reactions or sensitization in the occupational setting in Spain, Italy, Sicilia or South Africa. But no data is available in France. In this context, the investigators propose to determine and compare the frequency and characteristics of fish allergy in fish workers (fishermen and fish-processing factory workers) and a control population of workers without occupational exposure to fish, in Boulogne-sur-Mer, which is an important fishing port in France, and the first European center for fish processing.
Study for Promotion of Health in Recycling Lead (SPHERL) is a prospective 2-year follow-up study of lead workers with exposure levels varying between and within individuals. SPHERL addresses to what extent between-subject differences or within-subject changes in lead exposure may have a measurable impact on blood pressure, the cardiovascular system, renal function, the autonomic nervous system, peripheral nervous conduction velocity, and neurocognitive function. At the beginning of December 2015, 70 participants were included in the study.
