If you start a call with one of the supported HD cameras, and then switch to a standard-definition. These included the Swedish Q16 symptom questionnaire for evaluating solvent toxicity Lundberg et al. As several of these questionnaires were based on solvent toxicity, we were careful to add additional questions more closely associated with heavy metal toxicity.
Our approach to obtaining symptom information is unique in that it distinguishes between current today and recent over the past 3 months symptoms.
In addition, recent symptoms are classified by their duration, allowing definition of chronic symptoms. All 45 symptoms included in our checklist are appropriate for assignment of recent and chronic scores.
However, only 27 symptoms are appropriate for assignment of current scores, as they require more than one day to evaluate e. We believe that distinguishing these various types of symptoms, an uncommon practice, is important for properly characterizing and understanding responses to toxic insults.
Current today's symptoms were scored using only their intensity, whereas recent symptoms were scored using the product of their intensity and frequency. Symptom intensity and frequency are measured using five-point scales. Thus, chronic symptom scores were set equal to their corresponding recent symptom score if they had duration of at least one year, and otherwise were set to zero.
To reduce the number of variables in these analyses, we created a priori symptom groups see Table 1. Our symptom checklist and this a priori symptom grouping have been successfully used in a number of our previous studies. Echeverria et al. The score for each symptom group is equal to the highest maximum individual symptom score within that group.
This scoring scheme is based on the concept that different body systems might respond to toxic exposures through a variety of symptoms. As an alternative, we also evaluated group scores based on the sum of individual scores within each group. Statistical analyses. Cross-sectional analyses were conducted using SPSS. A data file was constructed which contained all symptom and mood scores, measures of exposure to elemental mercury both current and chronic , the BDNF polymorphism score, and covariates.
These conversions usually have a better linear association with toxic effects. A chronic mercury exposure index was created for participants by summing the contribution of each of their reported dental-related jobs. The weighting factor was included as it was clear from our previous analysis of urinary mercury levels in dental populations, and from comparisons with earlier studies, that dental exposure to mercury had dropped significantly over the last few decades.
In fact, since , the mean urinary mercury concentrations for dentists had begun to approach the concentrations observed among the general population. Finally, in the analyses, the square root of this index was employed to make its distribution closer to normal reducing the extended right tail. This type of weighted exposure assessment has been employed in many occupational studies. In particular, we have employed it successfully in our previous dental studies Echeverria et al.
Potential covariates evaluated in the analyses included demographic, dietary, medical history, and medication use factors.
Simple correlations were run between all outcomes mood and symptoms and the risk factors acute and chronic exposure and BDNF status to determine which associations we should focus on had a basic relationship. Simple correlations between these factors and the covariates were also run to evaluate which may be confounders. We were aware that symptoms could easily influence medication use and were cautious about the potential to over-control for covariates in our analyses.
Stepwise regression analyses were performed to evaluate the effects of current and chronic exposure, BDNF, and covariate factors on the associations of primary concern.
These evaluations resulted in a final base model for all analyses. This base model included all three risk factors urinary mercury, chronic mercury index, and BDNF status , as well as age and race as independent variables. These additional covariates are all dichotomous variables regarding health history and included 1 have a physical impairment, 2 history of respiratory problems, 3 history of circulatory problems, 4 history of sensory problems, 5 history of endocrine problems, and 6 history of major operations.
Finally, dentists males and dental assistants females were analyzed separately. It is clear from the very structure of the study that these two groups are different in many ways, and that it would be difficult to control for these differences in the analyses.
These differences include gender, age, education and training, social status and income, and the clear difference in their power relationship at work. Initial analyses disclosed no significant confounding from dietary or medication factors. Those medication factors that were strongly related to symptoms were either not related or only weakly related to mercury exposure or BDNF status.
They generally did not affect the direction and strength of the associations as measured by beta values. Two demographic factors, age and race, were important in a number of associations. Furthermore, several medical history questions were significant for some symptoms. Table 2 shows the characteristics of the male dentists and female dental assistants included in this study.
While most participants in both groups were Caucasian, spoke English as their first language, and were right handed, the percentages for each of these were significantly higher for dentists than for dental assistants. As expected, dentists were older, scored higher on their vocabulary tests, had higher levels of education, and had substantially higher incomes.
Coffee consumption was approximately equal between the two groups, but dentists consumed more alcohol although moderate amounts and fewer cigarettes. Concerning the three target risk factors, dentists had significantly higher spot urinary mercury concentrations and higher cumulative indices of exposure. Both groups had remarkably similar distributions of the BDNF polymorphism. Table 3 shows the average symptom score and percentage of each gender group reporting symptoms by symptom category.
It is clear that dental assistants females reported substantially higher levels of symptoms than did dentists males , indicating that dental assistants either suffer more symptoms or are more willing to report symptoms than their male dentist counterparts. These results given slope, standard error, beta, and significance levels are for the specific risk factor within the full model. Of the 23 associations with symptoms observed at this significance level, 17 were among females dental assistants , and 6 among males dentists.
In only three cases were the associations in the unexpected direction italicized in Table 4 , i. All three associations with mood scales observed at this significance level were among dental assistants and in the expected direction. Reported regression statistics are for each specific risk factor parameter. All models contain age and race as covariates. There were only four significant associations between symptoms and acute exposure log urinary mercury , all among dental assistants.
Two associations were with today's symptoms confusion and anxiety and both of these were in the expected direction. The remaining two associations were with recent and chronic heart and lung symptoms, and they were in the unexpected direction.
There were 12 significant associations between symptoms and chronic exposure as measured by the chronic exposure index , 3 among dentists and 9 among dental assistants.
Among dentists, there were two associations in the expected direction for today's symptoms anxiety and headache and one in the unexpected direction for chronic chest symptoms.
Among dental assistants, all these associations were in the expected direction. One was with today's symptoms headache , four with recent symptoms coordination, memory, digestive system, and skin , and four with chronic symptoms coordination, depression, memory, and skin. There were also seven significant associations between symptoms and BDNF status, all in the expected direction.
Among dentists, there were three associations, two with today's symptoms anxiety and coordination , and one with chronic heart and lung symptoms. Among dental assistants, there were four associations, two with today's symptoms anxiety and digestive system , one with recent anxiety symptoms, and one with chronic anxiety symptoms.
These were for the depression, vigor, and overall scales, and all were in the expected direction increased depression and overall scores, and decreased vigor with observed BDNF polymorphism. It should be noted that interactions between mercury exposure and BDNF status with respect to their associations with symptom scores and mood scales were evaluated, but none was observed. It does appear, at least in these analyses, that these were multiplicatively independent factors.
However, there were a number of cases where mercury exposure and BDNF status were additive with respect to their associations with the same symptom group. Among dentists, today's anxiety symptoms and chronic heart and lung symptoms were associated with both the chronic mercury index and BDNF status although the association between chronic exposure and chronic chest symptoms was in the unexpected direction.
Among dental assistants, today's anxiety was associated with both acute mercury exposure and BDNF status, whereas chronic memory loss was associated with both the chronic mercury index and BDNF status. Table 5 is included to illustrate the actual projected magnitude of effects for the three risk factors on symptom scores based on theoretical regression analyses using selected baseline and exposed status. This is useful for understanding the real-world effects of dental mercury exposure.
Our theoretical exposed population is also based on average age and dominant race. However, their three risk factors are now BDNF set to double-substitution polymorphism met-met , and both current and historical mercury exposures set to relatively high, but reasonable exposures approximately one standard deviation above the observed average value for the dentist population. The chronic exposure index for exposed status is 2, with a square root of 50, or approximately one standard deviation above the average square root of the chronic index observed among dentists.
The present results have several striking features that require discussion. First of these are the very high prevalence of some of the more important symptoms, especially anxiety, depression, and memory loss. Either very high or low prevalence can be a problem for studies that rely on dichotomous outcomes, as both create a lack of room for observing variation. However, our use of symptom scores rather than simple checklists has eliminated this problem.
These results indicate that it is the intensity and frequency of symptoms that vary with risk factors, not simply their prevalence. The substantial variation between current and recent symptoms also suggests that this is a useful distinction. The second striking feature in this study is the heavy predominance of observed associations among female subjects dental assistants as compared to males dentists.
While this may be associated with the higher prevalence of symptoms reported by females than males, it is more likely associated with females reporting a greater range of intensity and frequency than males, creating greater room for observing the association.
As stated earlier, dentists and dental assistants have many differences between them that may account for these observations.
The distinct social roles men and women play in our society, and especially in the workplace, could be important factors explaining the observed differences. There may also be specific occupational factors involved. Dentists, unlike dental assistants, use vibrating tools such as drills , which might be risk factors for some of these symptoms.
The use of vibrating tools would not necessarily be associated with the level of mercury exposure given the increasing use of non-mercury fillings, and thus may mask otherwise observable associations.
Nevertheless, our results are based on dose—response analyses conducted within each group separately. Thus, we would expect to see strong effects independent of the differences between these two groups. Finally, the strength of this study is not in the high significance of the observed associations, many of which were borderline, but in the consistency of the observed change occurring in the expected direction. In addition, all 3 associations meeting our criteria between BDNF polymorphism and mood scales also were in the expected direction.
These include coordination, memory loss, anxiety, depression, and headaches. There is no clear explanation for these associations. They may be random, or they may possibly be associated with other dental exposures that may coincide with mercury exposure, such as nitrous oxide.
It is interesting that all three observations of associations in the unexpected direction are associated with symptoms of the heart and lung. Many researchers believe that when conducting studies with multiple outcomes it is necessary to use a corrected or stricter alpha cutoff level for considering results significant. We obviously do not concur in the case of this study. An adjusted alpha level can be appropriate when expecting that any one of many outcomes measured would be of importance with respect to the risk factors.
However, as in this case, when we fully expected to see an array of results, we believe that it is far more important to assess the consistency of the direction of the association within the array of results than to worry about the individual alpha level of each result. If there were no true associations, we would expect to see chance observed associations randomly distributed across positive and negative directions.
The public health significance of these finding is of particular concern. In Washington State, our sample of 2, dental professionals — had mean urinary Hg levels of 2. Very well built with extremely detailed tidy construction. Doesn't run hot at all and the rated power consumption of watt is misleading. That said the smoothness in the sound produced when matched well comes very close. The amplifiers base sound signature is towards being bright and easily sounds harsh.
This amplifier definitely delivers enough punch and control. Alternatively can use the tone controls to balance. Furthermore by-passing the preamp circuit via the direct input mode gives a better detailed sound. The tone controls are very handy but do take away a bit from the clarity from the former.
