Perceptions of Public Health 3.0: Concordance Between Public Health Agency Leaders and Employees
CONTEXT AND BACKGROUND:
The newest era of public health, deemed "Public Health 3.0," supports cross-sector collaborations to address social determinants of health. These activities often require collaborations with nontraditional public health entities. As this new era begins, it is important to understand perceptions of the public health workforce with regard to Public Health 3.0.
OBJECTIVE:
To assess perceptions of support toward Public Health 3.0 activities by the public health workforce, identify characteristics associated with support, and measure concordance in support between agency directors and the general workforce.
DESIGN:
This cross-sectional study utilizes the 2017 Public Health Workforce Interests and Needs Survey to understand support and concordance regarding Public Health 3.0 activities by a nationally representative sample of governmental public health employees. Logistic regression models are used to identify characteristics associated with support of each 3.0 activity and concordance.
MAIN OUTCOME MEASURES:
Governmental public health employees' opinions on how involved their agency should be in the K-12 education system, the economy, the built environment, transportation, housing, social connectedness, and health equity within their jurisdiction and concordance in support of involvement between agency directors and the general workforce.
RESULTS:
Overall, individual perceptions supporting involvement were highest for health equity and social connectedness and lowest for transportation. Supervisory status, education, and being at a local health department were associated with greater odds of supporting all 3.0 activities. Concordance with agency directors was greatest among other executives relative to nonsupervisors.
CONCLUSIONS:
There is overall generally high support of many 3.0 activities, but there are gaps in agreement by supervisory status, gender, race/ethnicity, education, role type, and jurisdiction. Findings may help support agency leaders in better communicating the role of their agencies in Public Health 3.0 activities, and workforce education regarding such activities may be necessary for the success of Public Health 3.0's success
The Relationship Between Health Department Accreditation and Workforce Satisfaction, Retention, and Training Needs
BACKGROUND:
To improve quality and consistency of health departments, a voluntary accreditation process was developed by the Public Health Accreditation Board. Understanding accreditation's role as a mediator in workforce training needs, satisfaction, and awareness is important for continued improvement for governmental public health.
OBJECTIVE:
To compare differences in training needs, satisfaction/intent to leave, and awareness of public health concepts for state and local health department staff with regard to their agency's accreditation status.
DESIGN:
This cross-sectional study considered the association between agency accreditation status and individual perceptions of training needs, satisfaction, intent to leave, and awareness of public health concepts, using 2017 Public Health Workforce Interests and Needs Survey (PH WINS) data. Respondents were categorized on the basis of whether their agencies (at the time of survey) were (1) uninvolved in accreditation, (2) formally involved in accreditation, or (3) accredited.
RESULTS:
Multivariate logistic regression models found several significant differences, including the following: individuals from involved state agencies were less likely to report having had their training needs assessed; staff from accredited and involved agencies identified more gaps in selected skills; and employees of accredited agencies were more aware of quality improvement. While state employees in accredited and formally involved agencies reported less job satisfaction, there were no significant differences in intent to leave or burnout. Differences were identified concerning awareness of various public health concepts, especially among respondents in state agencies.
CONCLUSIONS:
While some findings were consistent with past research (eg, link between accreditation and quality improvement), others were not (eg, job satisfaction). Several self-reported skill gaps were unanticipated, given accreditation's emphasis on training. Potentially, as staff are exposed to accreditation topics, they gain more appreciation of skills development needs. Findings suggest opportunities to strengthen workforce development components when revising accreditation measures
Estrogen receptor variants in ER-positive basal-type breast cancers responding to therapy like ER-negative breast cancers
Immunohistochemically ER-positive HER2-negative (ER+HER2−) breast cancers are classified clinically as Luminal-type. We showed
previously that molecular subtyping using the 80-gene signature (80-GS) reclassified a subset of ER+HER2− tumors to molecular
Basal-type. We report here that molecular reclassification is associated with expression of dominant-negative ER variants and
evaluate response to neoadjuvant therapy and outcome in the prospective neoadjuvant NBRST study (NCT01479101). The 80-GS
reclassified 91 of 694 (13.1%) immunohistochemically Luminal-type tumors to molecular Basal-type. Importantly, all 91 discordant
tumors were classified as high-risk, whereas only 66.9% of ER+/Luminal-type tumors were classified at high-risk for disease
recurrence (i.e., Luminal B) (P < 0.001). ER variant mRNA (ERΔ3, ERΔ7, and ERα-36) analysis performed on 84 ER+/Basal tumors and
48 ER+/Luminal B control tumors revealed that total ER mRNA was significantly lower in ER+/Basal tumors. The relative expression
of ERΔ7/total ER was significantly higher in ER+/Basal tumors compared to ER+/Luminal B tumors (P < 0.001). ER+/Basal patients
had similar pathological complete response (pCR) rates following neoadjuvant chemotherapy as ER−/Basal patients (34.3 vs.
37.6%), and much higher than ER+/Luminal A or B patients (2.3 and 5.8%, respectively). Furthermore, 3-year distant metastasis-free
interval (DMFI) for ER+/Basal patients was 65.8%, significantly lower than 96.3 and 88.9% for ER+/Luminal A and B patients,
respectively, (log-rank P < 0.001). Significantly lower total ER mRNA and increased relative ERΔ7 dominant-negative variant
expression provides a rationale why ER+/Basal breast cancers are molecularly ER-negative. Identification of this substantial subset
of patients is clinically relevant because of the higher pCR rate to neoadjuvant chemotherapy and correlation with clinical outcome

Impact of Tumor Size on Probability of Pathologic Complete Response After Neoadjuvant Chemotherapy
Extent and patterns of community collaboration in local health departments: An exploratory survey
<p>Abstract</p> <p>Background</p> <p>Local public health departments (LHDs) in the United States have been encouraged to collaborate with various other community organizations and individuals. Current research suggests that many forms of active partnering are ongoing, and there are numerous examples of LHD collaboration with a specific organization for a specific purpose or program. However, no existing research has attempted to characterize collaboration, for the defined purpose of setting community health status priorities, between a defined population of local officials and a defined group of alternative partnering organizations. The specific aims of this study were to 1) determine the range of collaborative involvement exhibited by a study population of local public health officials, and, 2) characterize the patterns of the selection of organizations/individuals involved with LHDs in the process of setting community health status priorities.</p> <p>Methods</p> <p>Local health department officials in North Carolina (n = 53) responded to an exploratory survey about their levels of involvement with eight types of possible collaborator organizations and individuals. Descriptive statistics and the stochastic clustering technique of Self-Organizing Maps (SOM) were used to characterize their collaboration.</p> <p>Results</p> <p>Local health officials vary extensively in their level of collaboration with external collaborators. While the range of total involvement varies, the patterns of involvement for this specific function are relatively uniform. That is, regardless of the total level of involvement (low, medium or high), officials maintain similar hierarchical preference rankings with Community Advisory Boards and Local Boards of Health most involved and Experts and Elected Officials least involved.</p> <p>Conclusion</p> <p>The extent and patterns of collaboration among LHDs with other community stakeholders for a specific function can be described and ultimately related to outcome measures of LHD performance.</p
Gene expression of circulating tumour cells in breast cancer patients
<p>Abstract</p> <p>Background</p> <p>The diagnostic tools to predict the prognosis in patients suffering from breast cancer (BC) need further improvements. New technological achievements like the gene profiling of circulating tumour cells (CTC) could help identify new prognostic markers in the clinical setting. Furthermore, gene expression patterns of CTC might provide important informations on the mechanisms of tumour cell metastasation.</p> <p>Materials and methods</p> <p>We performed realtime-PCR and multiplex-PCR analyses following immunomagnetic separation of CTC. Peripheral blood (PB) samples of 63 patients with breast cancer of various stages were analyzed and compared to a control group of 14 healthy individuals. After reverse-transcription, we performed multiplex PCR using primers for the genes <it>ga733.3, muc-1 </it>and <it>c-erbB2. Mammaglobin1, spdef </it>and <it>c-erbB2 </it>were analyzed applying realtime-PCR.</p> <p>Results</p> <p><it>ga733.2 </it>overexpression was found in 12.7% of breast cancer cases, <it>muc-1 </it>in 15.9%, <it>mgb1 </it>in 9.1% and <it>spdef </it>in 12.1%. In this study, <it>c-erbB2 </it>did not show any significant correlation to BC, possibly due to a highly ambient expression. Besides single gene analyses, gene profiles were additionally evaluated. Highly significant correlations to BC were found in single gene analyses of <it>ga733.2 </it>and <it>muc-1 </it>and in gene profile analyses of <it>ga733.3</it>*<it>muc-1 </it>and GA7 <it>ga733.3</it>*muc-1*<it>mgb1</it>*<it>spdef</it>.</p> <p>Conclusion</p> <p>Our study reveals that the single genes <it>ga733.3, muc-1 </it>and the gene profiles <it>ga733.3</it>*<it>muc-1 </it>and <it>ga733.3</it>*3<it>muc-1</it>*<it>mgb1</it>*<it>spdef </it>can serve as markers for the detection of CTC in BC. The multigene analyses found highly positive levels in BC patients. Our study indicates that not single gene analyses but subtle patterns of multiple genes lead to rising accuracy and low loss of specificity in detection of breast cancer cases.</p
Completion Dissection or Observation for Sentinel-Node Metastasis in Melanoma.
Sentinel-lymph-node biopsy is associated with increased melanoma-specific survival (i.e., survival until death from melanoma) among patients with node-positive intermediate-thickness melanomas (1.2 to 3.5 mm). The value of completion lymph-node dissection for patients with sentinel-node metastases is not clear.
In an international trial, we randomly assigned patients with sentinel-node metastases detected by means of standard pathological assessment or a multimarker molecular assay to immediate completion lymph-node dissection (dissection group) or nodal observation with ultrasonography (observation group). The primary end point was melanoma-specific survival. Secondary end points included disease-free survival and the cumulative rate of nonsentinel-node metastasis.
Immediate completion lymph-node dissection was not associated with increased melanoma-specific survival among 1934 patients with data that could be evaluated in an intention-to-treat analysis or among 1755 patients in the per-protocol analysis. In the per-protocol analysis, the mean (±SE) 3-year rate of melanoma-specific survival was similar in the dissection group and the observation group (86±1.3% and 86±1.2%, respectively; P=0.42 by the log-rank test) at a median follow-up of 43 months. The rate of disease-free survival was slightly higher in the dissection group than in the observation group (68±1.7% and 63±1.7%, respectively; P=0.05 by the log-rank test) at 3 years, based on an increased rate of disease control in the regional nodes at 3 years (92±1.0% vs. 77±1.5%; P<0.001 by the log-rank test); these results must be interpreted with caution. Nonsentinel-node metastases, identified in 11.5% of the patients in the dissection group, were a strong, independent prognostic factor for recurrence (hazard ratio, 1.78; P=0.005). Lymphedema was observed in 24.1% of the patients in the dissection group and in 6.3% of those in the observation group.
Immediate completion lymph-node dissection increased the rate of regional disease control and provided prognostic information but did not increase melanoma-specific survival among patients with melanoma and sentinel-node metastases.

Serial expression analysis of breast tumors during neoadjuvant chemotherapy reveals changes in cell cycle and immune pathways associated with recurrence and response
Abstract Introduction The molecular biology involving neoadjuvant chemotherapy (NAC) response is poorly understood. To elucidate the impact of NAC on the breast cancer transcriptome and its association with clinical outcome, we analyzed gene expression data derived from serial tumor samples of patients with breast cancer who received NAC in the I-SPY 1 TRIAL. Methods Expression data were collected before treatment (T1), 24–96 hours after initiation of chemotherapy (T2) and at surgery (TS). Expression levels between T1 and T2 (T1 vs. T2; n = 36) and between T1 and TS (T1 vs. TS; n = 39) were compared. Subtype was assigned using the PAM50 gene signature. Differences in early gene expression changes (T2 − T1) between responders and nonresponders, as defined by residual cancer burden, were evaluated. Cox proportional hazards modeling was used to identify genes in residual tumors associated with recurrence-free survival (RFS). Pathway analysis was performed with Ingenuity software. Results When we compared expression profiles at T1 vs. T2 and at T1 vs. TS, we detected significantly altered expression of 150 and 59 transcripts, respectively. We observed notable downregulation of proliferation and immune-related genes at T2. Lower concordance in subtype assignment was observed between T1 and TS (62 %) than between T1 and T2 (75 %). Analysis of early gene expression changes (T2 − T1) revealed that decreased expression of cell cycle inhibitors was associated with poor response. Increased interferon signaling (TS − T1) and high expression of cell proliferation genes in residual tumors (TS) were associated with reduced RFS. Conclusions Serial gene expression analysis revealed candidate immune and proliferation pathways associated with response and recurrence. Larger studies incorporating the approach described here are warranted to identify predictive and prognostic biomarkers in the NAC setting for specific targeted therapies.
