However, there is a paucity of research on the joint effects of metal mixtures on health outcomes, even though human exposure to metal mixtures occurs more often than exposure to isolated metals (Choudhury and Mudipalli 2008).
Incomplete PEP was associated more often with exposures to dogs (42%) and cats (42%) than to other species.
Cases more often reported worksite exposure to heavy metals, other metal dust (such as aluminum, copper, chromium, tin), certain silicates (such as sand, cement, coal, rock, grain dust), solvents (such as varnish & paints, glue, crude oil, fuel, diesel, toluene), and welding and soldering fumes.
Children who live in older homes are tested more often for lead exposure.
Based on an arbitrary threshold set at a 10-fold increase of necrotic cells, CNTs < 8 nm induced slightly more often (in 5/24 exposures of EAhy926 cells and 3/24 exposures of L929 cells) necrosis than thick >20 nm CNTs (2/24 exposures of EAhy926 cells and 1/24 exposures of L929 cells).
For each age group, except the >85-year age group, female patients received PEP more often from cat exposures and male patients more often from dog exposures.
This approach was chosen to minimize recall bias that could arise because cases in the past were likely asked more often for potential exposures than controls.
Haematological toxicity, used as an indirect measure of bone marrow exposure, more often occurs during treatment, and serious cytopenia (grade 3 or 4 according to the National Cancer Institute's Common Terminology Criteria for Adverse Events, version 3.0) has been described in 10%% of patients in larger reports [2, 8].
Seasonal influenza vaccination coverage in the Netherlands was similar to pandemic influenza vaccination coverage but consistently occurred earlier and therefore was more often classed as past exposure (table 4).
This illustrated that with serious exposure at sites close to the head, the patients were more likely to seek medical service, and that lighter exposure more often was ignored.
They were more often associated with external radiation exposure, not always with internal exposure.
