Public health educators' participation in teams: implications for preparation and practice

Collaboration among public health organizations is essential to ensuring the health of the public. Much of the day-to-day work of public health educators is done in groups or teams or in consultation with others. This study examined the extent of health educators' work in teams as a proxy for collaboration. Health educators participated in an average of four teams per individual; three of these were interorganizational teams. Moreover, 40% of the respondents participated in five or more teams. Health educators supervised by other health educators were more likely to work in interorganizational teams than were those supervised by other professionals. Certified Health Education Specialists were more likely to participate in intraorganizational teams. Curricula in academic programs should reflect the extensive teamwork in which health educators are involved. Employers need to provide health educators with grounding in organizational priorities and support to carry out their collaborative work.     

Validation of the EntericBio Panel II® multiplex polymerase chain reaction system for detection of Campylobacter spp., Salmonella spp., Shigella spp., and verotoxigenic E. coli for use in a clinical diagnostic setting

A total of 717 faeces samples were tested prospectively using the EntericBio Panel II® detection system (Serosep, Limerick, Ireland), in parallel with routine laboratory testing, which combines the EntericBio® system with retrospective culture of each specimen where a target is detected. Discrepancy analysis was conducted using molecular methods. The EntericBio Panel II® assay produced 585 negative and 132 positive results, namely, Campylobacter spp. (n = 66); SLT 1 and/or SLT 2 (n = 64); Salmonella spp. (n = 5); and Shigella spp. (n = 0). Three samples were positive for more than 1 target. Of these results, 4 Campylobacter spp. detections and 4 SLT 1/ SLT 2 detections remained unconfirmed, and the system failed to detect 2 Campylobacter spp. targets detected by routine laboratory detection. The sensitivity, specificity, positive predictive value, negative predictive value, and efficiency were calculated to be 98.4%, 98.7%, 93.9%, 99.7%, and 98.6%, respectively.     

The dosimetric impact of supraclavicular nodal irradiation on the thyroid gland in patients with breast cancer

PurposeThe thyroid is not routinely considered an organ at risk in supraclavicular (SC) nodal radiation therapy (RT) for breast cancer. We compared the dosimetric impact of the following 2 RT planning techniques on the thyroid: (1) conventional single anterior field to encompass the SC nodal volume defined clinically; and (2) 3-dimensional conformal radiation therapy (3DCRT) planning to encompass the computed tomography (CT)-contoured SC nodal volume.Methods and MaterialsThe thyroid, SC nodal volumes, and organs at risk were contoured on the planning CT of 20 patients who received 50 Gy in 2-Gy daily fractions to the breast or chest wall, and SC nodes. Comparisons of dosimetric parameters between the techniques were performed: thyroid, mean and maximum dose, V5, V30, and V50 (percentage of thyroid receiving ≥ 5 Gy, ≥ 30 Gy, and ≥ 50 Gy, respectively); SC nodal volume, homogeneity index (HI, percentage volume receiving 95%-107% of prescribed dose); and maximum doses of spinal cord and brachial plexus. Anatomic characteristics that influenced the dose distributions were investigated.ResultsThe 3DCRT planning technique significantly increased all thyroid dosimetric measures (mean dose 17.2 Gy vs 26.7 Gy; maximum dose 48.5 Gy vs 51.9 Gy; V5 45.7% vs 64.9%; V30 33.7% vs 48%; and V50 0.6% vs 26.7%; P < .001). It improved HI for the SC nodal volumes (P < .001) but resulted in higher maximum doses to the spinal cord (6.1 Gy vs 30 Gy) and brachial plexus (43.2 Gy vs 51.4 Gy). The thyroid volume and depth of SC nodes did not influence the thyroid dose distribution. The depth of SC nodes impacted on the HI of SC nodal volumes in the conventional technique (P = .004).ConclusionsThe 3DCRT planning improved dosimetric coverage of the SC nodal volume but increased thyroid radiation doses. The potential adverse effects of incidental thyroid irradiation should be considered while improving dosimetric coverage in SC nodal irradiation for breast cancer.     

Alternative medicine utilization by African Americans and improving life expectancy: is there a correlation?

The life expectancy of African Americans and Caucasians has been increasing in the United States and in many other countries around the world since the late 1800s. However, as long as statistics have been accrued on race and ethnicity, the life expectancy of African Americans and Blacks in general has been significantly lower than that of Caucasians. Basic public health and medical preventive education is needed because higher cardiovascular disease (CVD) rates is one of the primary reasons for the differences between life expectancy between African Americans and Caucasians. It is also of an apparent separate but perhaps related interest that several recent preliminary studies suggest that African Americans, more than any other race, may have some of the lowest uses of alternative medicine due to skepticism, as well as educational efforts and trust in their health care professional. Despite a common belief that African Americans harbor profound distrust of specific areas of the medical profession, it is of interest that this finding has not held validity in the area of alternative medicine. Therefore, since lifestyle changes are considered alternatives in most of these studies, this would suggest that a greater educational emphasis on behavioral modification could establish a foundation or a model of preventive medical education that can be utilized for underserved populations around the world.
