Active clinical trials for "Occupational Diseases"

SUSPECT is a prospective, single-center, cohort study of 250 military aircrew at the Center for Man in Aviation, Royal Netherlands Air Force. All asymptomatic aircrew (≥40 years) are asked to undergo a coronary CT scan on a voluntary basis, following the exercise electrocardiograms performed at their routine aeromedical examination. Coronary Artery Calcium score (CACS) and CCTA findings are reported.

The main objective is to identify specific risk factors for ANCA vasculitis of occupational and/or environmental origin (exposures identified by questioning, geographical distribution of cases) from the RNV3P data. The secondary objectives are as follows: Description of cases of ANCA vasculitis seen in French occupational pathology consultation centres: reasons for consultation, occupational and environmental etiologies described occupational situations responsible aptitude notices recognition as an occupational disease Identification of specific risk factors for ANCA vasculitis of occupational and/or environmental origin (exposures identified on questioning, geographical distribution of cases). For occupational and non-occupational cases of ANCA vasculitis: identification of difficulties encountered by patients at work and proposed work adaptations. Estimation of the number of applications for recognition of disabled worker status made within this patient group. Identification of clinical severity and autoimmune profiles of ANCA vasculitis of occupational and/or environmental origin.

Adverse events are also the cause of suffering in health professionals involved (second victims). This study has the aim of design and evaluates two applications for staff of hospital and primary care settings with the intention of improving their capacity to conduct Root Cause Analysis (RCA) and to help them introducing patient safety certification (PSC). A single-blind randomized controlled trial shall conduct with a control and an experimental group (N=84) in both cases. The characteristics of both apps shall specify based on the suggestions of health professionals and shall design for Android and IOS (for iPhone or Ipad). The randomly subjects in the control group shall receive oral and written information and the experimental group used App for two months. Pre- and post- measures shall include: patient safety knowledge and culture and self-perceived capacity to enhance RCA or follow-up PSC. In the experimental group, data shall also collect on their previous experience with information and communication technologies, their rating of each App. The inter-group intervention effects shall calculate by univariate linear models and ANOVA, with the pre- to post-intervention differences as the dependent variables.

The investigator proposes to perform a Phase I study assessing safety, efficacy, and biomarker response to the therapeutic interventions of Etanercept followed by mifepristone for veterans with Gulf War Illness. The investigator will conduct and repeat the exercise challenge before treatment and on therapy to assess the impact of the interventions on homeostatic regulation and the dynamic model identified in prior studies.

This study is one of several initiated by the investigators to reduce musculoskeletal injuries in patient care providers. Nurses have one of the highest incidences of work related back injuries of any profession. Over the past 20 years, efforts to reduce work-related injuries in nursing have been largely unsuccessful.

Airway macrophage impairment is a central feature in the immunopathogenesis of chronic obstructive pulmonary disease, regardless of smoking status.

Thousands of people are working daily in a dusty environment. Many studied reported respiratory symptoms and ventilatory disorders among Factory workers who exposed to cement dust. But the evidence for respiratory effect and daily activities over a long time of cement dust exposure has not been conclusive

Background: Induced sputum (IS) is a noninvasive methodology for evaluating airway inflammation in a large number of pulmonary diseases, i.e, Asthma, Chronic obstructive pulmonary disease and Interstitial Lung Diseases. Several studies have defined normal values and cut-off points for this technique based on cellular components of IS, such as percentages of eosinophils, neutrophils, macrophages and CD4/CD8 ratio of T cell lymphocytes. However, normal values and cut-off points for lymphocyte percentages indicative of pathology have not yet been established or validated. This component of IS has considerable clinical value. Similar to other constituents of IS, it can provide biological insights into the pathogenesis of respiratory disorders and contribute to establishing the diagnosis and guiding treatment management of a variety of airway diseases. The purposes of this study are to define normal values and cut-off points of lymphocytes in IS among individuals with respiratory disorders and healthy volunteers, and to verify the current reference values of the percentage of eosinophils, neutrophils and CD4/CD8 ratio in IS. Methods: A Cross Sectional study which includes a database on up to 900 patients who participated in various studies conducted in the Pulmonary Laboratory of Tel Aviv Sourasky Medical Center between 2005 to 2012 will be established. The study population will include patients diagnosed as having various pulmonary diseases and a group of healthy volunteers who will serve as controls. The cut-off for normal values of lymphocyte, eosinophil and neutrophil percentages and CD4/CD8 ratio in IS will be defined by using ROC curves and evaluating sensitivity and specificity. The comparison of the different values to those in the literature will be done by using the Spearman rank correlation. The results of this study will provide supplementary information on lymphocyte counts in IS for identifying and treating various respiratory diseases.

This is an observational study to examine the cardiovascular mechanisms of increased cardiovascular mortality in those with high activity occupations.

Objective: In addition to physical discomforts, work-related injuries and illnesses often result in various forms of hardships, including economic hardship, labor conflicts and legal disputes. The physical and psychological health conditions are likely to be worsen when the social supporting systems are not well functioning. In this study, the investigators aim to conduct in-depth interviews with injured workers to study their experiences with the social systems, including employment protection system, workers' compensation system, health care system and other social welfare systems, and to explore how the systems may affect workers' physical and psychological health. Methods: Face-to-face interviews will be conducted with a semi-structured questionnaire. Subjects who had ever experienced work-related injuries or diseases (including muscular skeletal disorders and work-related cardiovascular or cerebrovascular diseases) over the past 3 years are invited. The investigators anticipate to recruit a total of 60~100 cases, whom will be recruited through the assistance of occupational physicians, occupational health centers, labor groups and unions. Interview time will be limited to 1 hour. Anticipated results and contribution: Findings of this study will help to advance our knowledge concerning the functions of current social systems and the hardships of workers who suffer from work-related injuries and diseases. Suggestions will be provided for the improvements of current systems. Keywords: work-related injury, occupational disease, workers' compensation, psychological, policy.
