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.
NCT07200310
This study looks at whether working as a hot-air balloon pilot-being exposed to burner noise, changes in air pressure/temperature, and vertical acceleration-is linked to changes in hearing, Eustachian tube function, and vestibular (balance) function. Adult pilots from Cappadocia will be compared with adults who do not have these exposures. Approximately 90 participants are expected to be enrolled For contextual exposure information, representative in-field noise measurements during balloon operations and basic flight parameters may be documented Each participant will attend one visit (\~60 minutes) in an ENT/audiology laboratory. After a short questionnaire and an ear exam (otoscopy), the following non-invasive tests will be performed: tympanometry; tympanometry with simple maneuvers (Valsalva/Toynbee) to evaluate Eustachian tube function (ΔTPP); pure-tone audiometry (including extended high frequencies); otoacoustic emission tests (TEOAE and DPOAE); acoustic (stapedius) reflex thresholds; and a brief cervical vestibular evoked myogenic potential (cVEMP) test. Symptom-triggered questionnaires will also be used: for participants reporting tinnitus, the Tinnitus Handicap Inventory (THI); for those reporting dizziness, the Berg Balance Scale (BBS). No medications or blood tests are involved. Testing is safe and routinely used in clinical care. Risks are minimal (for example, temporary ear-canal pressure or brief dizziness). Testing will be stopped if any discomfort occurs. Personal information will be kept confidential, and results will be reported only in group form. Findings from this study may help improve occupational health guidance for hot-air balloon pilots.

NCT03670927
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.
NCT05811767
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?

An interventional study on the effects of repeated trunk flexion exposure on trunk neuromuscular properties.
NCT03855163
This study evaluates the effects of the Labour Inspection Authority's regulatory tools on workplace exposures to prevent employee ill health. Norwegian municipal enterprises with employees in the home care sector have been randomized to three different experimental groups and to one control group. We hypothesize a significant lower level of work environmental exposures and health complaints, after adjusting for pre-intervention measures, in the experimental groups compared to the control group.

The primary objective of the present trial is to compare the radiation attenuation provided by XPF caps (0.5mm lead-equivalent and 0.3mm lead-equivalent) to the standard protection (fabric cap, basically no protection) as measured in % radiation attenuation) during 150 days of fluoroscopy guided cardiology interventions. The second objective is to compare the operator comfort (rated on a visual analog scale) of wearing the XPF protection caps compared to the standard fabric caps.
NCT01611454
The PREFER II trial primary objective of the trial is to show how much radiation attenuation is provided by XPF thyroid collars in absolute and relative terms.
NCT04879082
Diffuse interstitial lung disease brings together a heterogeneous group of pulmonary pathologies, characterized by infiltrating and diffuse lesions of the pulmonary interstitium. The evolving risk of these ILD is pulmonary fibrosis, with the development of chronic respiratory failure. The process of the etiological diagnosis of ILD results from a multidisciplinary approach (pulmonologists, radiologists, occupational health specialists, anatomo-pathologists, etc…). Indeed, the multitude of possible causes of these diseases makes the etiological diagnosis difficult. Professional aetiologies are also frequently mentioned : pneumoconiosis, hypersensitivity pneumonitis, as a differential diagnosis. It therefore appears essential to deepen the professional aspect during the diagnostic process for ILD. Since May 2020, a professional interview has been systematically offered by the Occupational Pathology Consultation Center of the Hospital Center Lyon Sud, to patients followed by the team of Professor Vincent COTTIN, whose file was discussed in a multidisciplinary meeting. The data collected to constitute a database are the following variables: age, sex, diploma, professional course coded in CITP (International Standard Classification of Professions) and NAF (French Nomenclature of Activities), occupational exposures, smoking, risk factors non-professionals, clinical elements of ILD and elements relating to an occupational disease certificate. This database is anonymized.

NCT03678519
Flour milling is from the oldest trade industry. Several problems arise during functioning and maintenance operations. Production process involves the breakdown of grains to separate their outer covering and inner endosperm grinding to fine flour particles. Workers are at substantial risk with two main problems causing severe health issues and accidents. The first is the improper flour milling process including intake and final products collection systems. The second is the unawareness and unavailability of PPE.
NCT03532321
In hospitals, the improvement of working conditions is often considered secondarily to patient satisfaction. Previous studies, showing statistically significant relationships, suggested the impact of hospital departments' organization (staff / patient ratio, bed distribution, caregiver's assignment), of the work environment, and the working conditions on the infectious risk at the hospital departments. In addition, organizational hospital constraints and the organization of care could equally have a major impact on the physical and psychological health of care workers (stress, fatigue, job satisfaction). To date, available data suggest that determinants of occupational stress and fatigue are multifactorial. This research aims to develop an interdisciplinary approach to link two phenomena that are often studied independently while they are closely intertwined: working conditions and infectious risk in hospitals departments. Their main objective is to study the relationship between stress and caregiver fatigue at the work, organizational determinants and infectious risk for patients (healthcare-associated infections: HAIs) and for caregivers (blood exposure accidents: BEAs). The secondary objective is to analyze how the individual characteristics of the staff, the characteristics of their employment, and the overall organization in the hospital departments where they work interact to explain their physical and psychological state of health, on the one hand, and their behavior face to work (absenteeism, turnover and hand hygiene) on the other hand. The ultimate goal of this research is to be able to propose organizational strategies aimed at both reducing the probability of occurrence of healthcare-associated infections and preventing occupational risks for caregivers.
NCT00342394
This protocol describes an exposure assessment study of farmers in North Carolina and Iowa who personally apply the fungicides captan, thiophanate-methyl, and benomyl to apple and peach orchards. The exposure assessment will include environmental measurements as well as biological monitoring data. The biomonitoring data will be based on 24-hour urinary metabolites of the three fungicides selected for study. The study is being done in collaboration with the Argicultural Health Study (AHS), a large prospective health study of licensed private (farmer) and commercial applicators, and the spouses of private applicators. The AHS is sponsored by the National Cancer Institute, the National Institute of Environmental Health Sciences and the Environmental Protection Agency. The study described here will be conducted by the National Institute of Occupational Safety and Health. In summary, the objectives of this study are 1) to measure actual exposures to the target fungicides using both environmental and biological measures of exposure, 2) to identify and quantify major determinants of exposure, 3) to describe within- and between-worker exposure variability, and 4) to evaluate, to the extent possible, agreement between exposure estimates computed using the AHS exposure algorithms and exposure estimates based on actual measurements.

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.
