Characterizing the Role of International Graduates of the Epidemic Intelligence Service in Increasing the Epidemiological Capacity and Diversity of the United States Public Health Workforce.

CONTEXT: A trained and diverse public health workforce is needed to respond to public health threats. The Epidemic Intelligence Service (EIS) is an applied epidemiology training program. Most EIS officers are from the United States, but some are from other countries and bring unique perspectives and skills. OBJECTIVES/EVALUATION: To characterize international officers who participated in the EIS program and describe their employment settings after training completion. DESIGN: International officers were people who participated in EIS and who were not US citizens or permanent residents. We analyzed data from EIS's application database during 2009-2017 to describe officers' characteristics. We used data from the Centers for Disease Control and Prevention's (CDC's) workforce database for civil servants and EIS exit surveys to describe jobs taken after program completion. MAIN OUTCOME MEASURES: We described the characteristics of the international officers, jobs taken immediately after program completion, and duration of employment at CDC. RESULTS: Among 715 officers accepted in EIS classes of 2009-2017, 85 (12%) were international applicants, with citizenships from 40 different countries. Forty (47%) had 1 or more US postgraduate degrees, and 65 (76%) were physicians. Of 78 (92%) international officers with available employment data, 65 (83%) reported taking a job at CDC after program completion. The remaining took a public health job with an international entity (6%), academia (5%), or other jobs (5%). Among 65 international officers who remained working at CDC after graduation, the median employment duration was 5.2 years, including their 2 years in EIS. CONCLUSIONS: Most international EIS graduates remain at CDC after program completion, which strengthens the diversity and capacity of CDC's epidemiological workforce. Further evaluations are needed to determine the effects of pulling away crucial talent from other countries needing experienced epidemiologists and to what extent retaining those persons can benefit public health globally.

Patterns of persistent HPV infection after treatment for cervical intraepithelial neoplasia (CIN): A systematic review.

A systematic review of the literature was conducted to determine the estimates of and definitions for human papillomavirus (HPV) persistence in women following treatment of cervical intra-epithelial neoplasia (CIN). A total of 45 studies presented data on post-treatment HPV persistence among 6,106 women. Most studies assessed HPV persistence after loop excision (42%), followed by conization (7%), cryotherapy (11%), laser treatment (4%), interferon-alpha, therapeutic vaccination, and photodynamic therapy (2% each) and mixed treatment (38%). Baseline HPV testing was conducted before or at treatment for most studies (96%). Follow-up HPV testing ranged from 1.5 to 80 months after baseline. Median HPV persistence tended to decrease with increasing follow-up time, declining from 27% at 3 months after treatment to 21% at 6 months, 15% at 12 months, and 10% at 24 months. Post-treatment HPV persistence estimates varied widely and were influenced by patient age, HPV-type, detection method, treatment method, and minimum HPV post-treatment testing interval. Loop excision and conization appeared to outperform cryotherapy procedures in terms of their ability to clear HPV infection. This systematic review provides evidence for the substantial heterogeneity in post-treatment HPV DNA testing practices and persistence estimates.

'You must not confuse poverty with laziness': a case study on the power of discourse to reproduce diabetes inequalities.

The disproportionate impact of type 2 diabetes (T2DM) on low-income groups and the social and biological processes linking poverty and T2DM inequalities are well-documented. Moreover, millions of dollars are invested annually in programs aimed at reducing T2DM inequalities, yet these remain stubbornly high. Our article explores how public discourses influence T2DM and related health inequalities in a low-income neighborhood in Northern California, through a thematic analysis of interviews and focus groups of staff and clients at a non-governmental organization. We probe participants' beliefs vis-a-vis the causes of, and solutions to, T2DM inequalities and explore whether and how the discourses normalizing them are challenged. We find that staff identify the ultimate source of T2DM inequalities within health sufferers (i.e., their lifestyle choices, psychological makeup, or cultural preferences), even as they acknowledge the widespread poverty, unemployment, and other social determinants that present serious barriers to their health. Notably, we find this normalizing discourse .among clients themselves. While our study is empirical, its goal is primarily conceptual: to add to the evolving understanding of discourse as a social practice that may contribute both to status quo reproduction and to social change and resistance.

Lessons learned for public health workforce development: An evaluation of the centers for disease control and prevention's laboratory leadership service fellowship.

The Centers for Disease Control and Prevention launched the Laboratory Leadership Service (LLS) Fellowship Program in July 2015 to develop public health laboratory (PHL) leaders who will improve PHL quality and safety. This article describes a retrospective, summative evaluation to determine the extent to which LLS has met its short-term goals for PHL workforce development. The evaluation relied on existing data from routine LLS data collection and reporting, supplemented with a new alumni survey. The purpose of the design was threefold: 1) to reduce data collection burden on program staff and participants, 2) to assess the value and limits of routine fellowship data for comprehensive public health workforce development program evaluation, and 3) to identify ways to improve LLS's routine data collections for program evaluation. We used descriptive statistics, qualitative analysis, and participatory methods (i.e., a data party) to analyze and interpret data. Results show LLS short-term outcome achievement and highlight opportunities for program improvement, particularly related to the design of certain training requirements and for future evaluations. Overall, the evaluation contributes to lessons learned for PHL workforce development efforts, including how routine data collections can contribute to comprehensive public health workforce development evaluations.

Behavioral Health Providers' Experience with Changes in Services for People Experiencing Homelessness During COVID-19, USA, August-October 2020.

The COVID-19 pandemic caused disruptions in behavioral health services (BHS), essential for people experiencing homelessness (PEH). BHS changes created barriers to care and opportunities for innovative strategies for reaching PEH. The authors conducted 50 qualitative interviews with behavioral health providers in the USA during August-October 2020 to explore their observations of BHS changes for PEH. Interviews were transcribed and entered into MAXQDA for analysis and to identify salient themes. The largest impact from COVID-19 was the closure or limited hours for BHS and homeless shelters due to mandated "stay-at-home" orders or staff working remotely leading to a disconnection in services and housing linkages. Most providers initiated telehealth services for clients, yielding positive outcomes. Implications for BHS are the need for long-term strategies, such as advances in communication technology to support BHS and homeless services and to ensure the needs of underserved populations are met during public health emergencies.

The twin epidemics of poverty and diabetes: understanding diabetes disparities in a low-income Latino and immigrant neighborhood.

In the United States, low-income immigrant groups experience greater health disparities and worse health-related outcomes than Whites, including but not limited to higher rates of type 2 diabetes (T2DM). The prevention and adequate management of T2DM are, to a great extent, contingent on access to healthy food environments. This exploratory study examines "upstream" antecedent factors contributing to "downstream" health disparities, with a focus on disparities in the structural sources of T2DM risk, especially food environments. Our target group is Latino immigrants receiving services from a non-profit organization (NGO) in Northern California. Methods are mixed and data include focus groups and surveys of our target group, interviews to NGO staff members, and estimation of the thrifty food market basket in local grocery stores. We find that while participants identify T2DM as the greatest health problem in the community, access to healthy foods is severely restricted, geographically, culturally, and economically, with 100% of participants relying on formal or informal food assistance and local food stores offering limited variety of healthy foods and at unaffordable prices. While this article is empirical, its goal is primarily conceptual--to integrate empirical findings with the growing literature underscoring the sociopolitical context of the social determinants of health in general and of T2DM disparities in particular. We propose that interventions to reduce T2DM and comparable health disparities must incorporate a social justice perspective that guarantees a right to adequate food and other health-relevant environments, and concomitantly, a right to health.

Impact of calcium nitrate supplementation on the oxygen-carrying capacity of lactating sows and their offspring.

Calcium nitrate supplementation has recently been suggested to provide potential benefits to sows and, in particular, their offspring when administered at a level of 1,200 ppm in feed shortly before farrowing through lactation. More specifically, nitrate supplementation has been suggested as one opportunity for improved placental and/or fetal blood flow and has been hypothesized in previous work to be important to the swine industry in light of the global trend toward larger litter sizes. The benefit is likely manifested through exposure to the nitrate moiety, but interestingly, nitrate has historically been considered a compound of concern for swine. High levels of nitrate once metabolized to nitrite can interfere with the oxygen-carrying capacity of hemoglobin, resulting in increased methemoglobin and, subsequently, methemoglobinemia (MetHb) if the animal is deprived of significant amounts of oxygen; however, the level of nitrate exposure necessary to induce MetHb in sows is not clearly defined. This work was undertaken to examine methemoglobin levels in sows and piglets exposed to the potentially beneficial levels of 1,200 and 6,000 ppm nitrate added to their diets over the course of the periparturient period. Other oxygen capacity blood variables were evaluated (e.g., hemoglobin, hematocrit, and various measures of hemoglobin and red blood cell volumes and concentrations), as well as performance endpoints (weight changes and feed intake) and general observations over the 27-d period. No evidence of treatment-related toxicity manifestation was observed at these supplemental levels. Nearly all oxygen-related variables were affected by time (independent of treatment), indicating adaptive general effects of farrowing. These findings support the hypothesis that MetHb is not a concern up to at least 6,000 ppm supplemental nitrate exposure, even in combination with additional nitrate in the sow's daily diet. This work is important to help swine producers understand that consideration of nitrate benefit should outweigh concern for risk of nitrate-induced toxicity.
