  2. 2. Lead in blood. ICP-MS studies of lead in plasma, blood and erythrocyte proteins

    Författare :Ingvar A Bergdahl; Avdelningen för arbets- och miljömedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; distribution; plasma; blood; erythrocytes; lead-binding prtoeins; delta-aminlevulinic acid dehydratase; inductively coupled plasma mass spectrometry; ALAD; arbetsmiljömedicin; Occupational health; industrial medicine; Lead; toxicity; ICP-MS; Yrkesmedicin;

    Sammanfattning : An inductively coupled plasma mass spectrometry (ICP-MS) method for the determination of lead in blood plasma has been developed. The detection limit was below 0.1 microgram/liter, and the precision 5%. There was no significant difference between levels in plasma and serum. LÄS MER

  3. 3. Depression among the very old

    Författare :Ellinor Bergdahl; Yngve Gustafson; Per Allard; Ingvar Karlsson; Umeå universitet; []
    Nyckelord :Psychiatry; very old; depression; prevalence; associated factors; five-year outcome; mortality; Psykiatri; Geriatrics; geriatrik;

    Sammanfattning : Emotional suffering in old age is largely caused by various psychiatric conditions, of which depression is the most common. Depression is associated with a decline in both well-being and daily functioning and reduces both morale and social capacity among the very old, which may produce high health and social costs for society.

  4. 4. Lead exposure in indigenous children of the Peruvian Amazon : seeking the hidden source,venturing into participatory research

    Författare :Cynthia Anticona Huaynate; Miguel San Sebastian; Ingvar Bergdahl; Mary Jean Brown; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; lead exposure; children; indigenous; Corrientes river; participatory research; Peruvian Amazon; Public health; folkhälsa;

    Sammanfattning : Introduction. In 2006, a Peruvian environmental agency reported the presence of elevated blood lead levels (BLLs) in indigenous communities of the Corrientes river basin. This is a territory in the Peruvian Amazon where oil activity has been associated with serious environmental effects, with impact on an ongoing social conflict. LÄS MER

  5. 5. Efficient strategies for collecting posture data using observation and direct measurement

    Författare :Per Liv; Svend Erik Mathiassen; Marina Heiden; Leif Nilsson; Ingvar Bergdahl; Stephen Bao; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Exposure assessment; arm elevation; exposure variability; variance components; random effects model; precision; bias; sample size; sample allocation; calibration; bootstrapping; Occupational and Environmental Medicine; arbets- och miljömedicin;

    Sammanfattning : Relationships between occupational physical exposures and risks of contracting musculoskeletal disorders are still not well understood; exposure-response relationships are scarce in the musculoskeletal epidemiology literature, and many epidemiological studies, including intervention studies, fail to reach conclusive results. Insufficient exposure assessment has been pointed out as a possible explanation for this deficiency. LÄS MER
