Previous research updated the mortality experience of North American synthetic rubber industry workers during the period 1944-1998, determined if leukemia and other cancers were associated with several employment factors and carried out Poisson regression analysis to examine exposure-response associations between estimated exposure to 1,3-butadiene (BD) or other chemicals and cancer. The present study used Cox regression procedures to examine further the exposure-response relationship between several unlagged and lagged, continuous, time-dependent BD exposure indices (BD parts per million (ppm)-years, the total number of exposures to BD concentrations >100 ppm ("peaks") and average intensity of BD) and leukemia, lymphoid neoplasms and myeloid neoplasms. All three BD exposure indices were associated positively with leukemia. Using continuous, untransformed BD ppm-years the regression coefficient (beta) from an analysis that controlled only for age was 2.9 x 10(-4) (p
The treatment-mix, treatment time, and dental status of 268 male industrial workers entitled to employer-provided dental care were studied. The data were collected from treatment records of the covered workers over the 5-year period 1989-93. Treatment time was based on clinical treatment time recorded per patient visit, and the treatment procedure codes were reclassified into a treatment-mix according to American Dental Association categories, with a modification combining endodontics and restorative treatment. The mean number of check-ups followed by prescribed treatment (treatment courses) during the 5 years was 3.7 among those who had entered the in-house dental care program prior to the monitored period (old attenders). Their treatment time was stable, 57-63 min per year, while the first-year mean treatment time (170 min) of those who had entered the program during the study period (new attenders) was significantly higher (P
Abstract Many genetic/genomic educational opportunities are available to assist nursing faculty in their knowledge and understanding of genetic/genomics. This study was conducted to assess advance practice nursing faculty members' current knowledge of medical genetics/genomics, their integration of genetics/genomics content into advance practice nursing curricula, any prior formal training/education in genetics/genomics, and their comfort level in teaching genetics/genomic content. A secondary aim was to conduct a comparative analysis of the 2010 data to a previous study conducted in 2005, to determine changes that have taken place during that time period. During a national nurse practitioner faculty conference, 85 nurse practitioner faculty voluntarily completed surveys. Approximately 70% of the 2010 faculty felt comfortable teaching basic genetic/genomic concepts compared to 50% in 2005. However, there continue to be education gaps in the genetic/genomic content taught to advance practice nursing students. If nurses are going to be a crucial member of the health-care team, they must achieve the requisite competencies to deliver the increasingly complex care patients require.
