  1. 1. Myocardial infarction and cardiac regulation in relation to vibration exposure

    Författare :Bodil Björ; Per Gustavsson; Umeå universitet; []
    Nyckelord :vibration exposure; myocardial infarction; cardiac regulation; exposure assessment; occupational exposure; epidemiology; cohort study; case-control study; Occupational and Environmental Medicine; arbets- och miljömedicin;

    Sammanfattning : The purpose of this thesis was to assess the possible risk of myocardial infarction in work entailing exposure to vibration, and to study whether there is any relation between short-term exposure to vibration and cardiac regulation. Epidemiological methods were applied to investigate a possible association between occupational exposure to vibration and myocardial infarction. LÄS MER

  2. 2. Blood exposure in health care : health care workers' and patients' experiences

    Författare :Ulla-Britt Lymer; Barbro Isaksson; Bengt Richt; Vivi-Anne Sundquist; Linköpings universitet; []
    Nyckelord :Blood-exposure; needle-stick; compliance; universal precautions; balancing; quaIity care; nursing; patients conceptions; grounded theory; phenomenography; MEDICINE; MEDICIN; blood-exposure; quality care;

    Sammanfattning : The general aim of this thesis was to describe and analyse health care workers' blood-exposure incidents, protective measures, and the motives behind decision making about risks and protective measures. The aim was also to procure knowledge about patients' conceptions about their care, and if precautions taken by the health care workers were included in quaiity care. LÄS MER

  3. 3. Isocyanates - assessment of human exposure

    Författare :Håkan Tinnerberg; Avdelningen för arbets- och miljömedicin; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pollution control; Miljöteknik; kontroll av utsläpp; Analytical chemistry; Analytisk kemi; exposure; biomonitoring; occupational; isophorone diisocyanate; hexamethylene diisocyanate; methylenediphenyl diisocyanate; toluene diisocyanate; amines; aminoisocyanates; polyurethane; isocyanates; Liquid chromatography; Environmental technology; mass spectrometry;

    Sammanfattning : Isocyanates are used mainly for manufacturing of polyurethane (PUR) foams, lacquers, elastomers and glues. The production of PUR exceeds 2 million tonnes per year and is increasing. Occupational exposure to isocyanates are associated with respiratory disorders. LÄS MER

  4. 4. Nonmalignant health effects of arsenic exposure

    Författare :Mahfuzar Rahman; Per Gustavsson; Linköpings universitet; []
    Nyckelord :arsenic; case-control study; cross-sectional study; diabetes mellitus; drinking water; epidemiology; exposure; keratosis; public health. hypertension; risk factors; MEDICINE; MEDICIN;

    Sammanfattning : This thesis comprises a series of studies concerning occupational and environmental exposure to arsenic and some novel chronic health effects of this element, namely diabetes mellitus and hypertension. Substantial prevalence of the well-known skin manifestations of arsenic ingestion was also found to occur as a result of environmental exposure through drinking water. LÄS MER

  5. 5. Exposure, telomere length, and cancer risk

    Författare :Huiqi Li; Avdelningen för arbets- och miljömedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; exposure; telomere; methylation; chromosomal aberration; cancer risk; rubber fumes; arsenic; welding fumes; diesel exhaust; particulate matter;

    Sammanfattning : Telomeres are tandem repeats of TTAGGG at the end of eukaryotic chromosomes. Telomeres play a key role in chromosome stability and regulation of the cellular lifespan. Telomeres are shortened during cell division, and probably, by not yet well characterised factors in the environment. LÄS MER
