Assessing and managing SARS-CoV-2 occupational health risk to workers handling residuals and biosolids.

Current wastewater worker guidance from the United States Environmental Protection Agency (USEPA) aligns with the Centers for Disease Control and Prevention (CDC) and the Occupational Safety and Health Administration (OSHA) recommendations and states that no additional specific protections against SARS-CoV-2, the virus that causes COVID-19 infections, are recommended for employees involved in wastewater management operations with residuals, sludge, and biosolids at water resource recovery facilities. The USEPA guidance references a document from 2002 that summarizes practices required for protection of workers handling class B biosolids to minimize exposure to pathogens including viruses. While there is no documented evidence that residuals or biosolids of any treatment level contain infectious SARS-CoV-2 or are a source of transmission of this current pandemic strain of coronavirus, this review summarizes and examines whether the provided federal guidance is sufficient to protect workers in view of currently available data on SARS-CoV-2 persistence and transmission. No currently available epidemiological data establishes a direct link between wastewater sludge or biosolids and risk of infection from the SARS-CoV-2. Despite shedding of the RNA of the virus in feces, there is no evidence supporting the presence or transmission of infectious SARS-CoV-2 through the wastewater system or in biosolids. In addition, this review presents previous epidemiologic data related to other non-enveloped viruses. Overall, the risk for exposure to SARS-CoV-2, or any pathogen, decreases with increasing treatment measures. As a result, the highest risk of exposure is related to spreading and handling untreated feces or stool, followed by untreated municipal sludge, the class B biosolids, while lowest risk is associated with spreading or handling Class A biosolids. This review reinforces federal recommendations and the importance of vigilance in applying occupational risk mitigation measures to protect public and occupational health.

Improving stereotypes: The impact of interprofessional education in pre-health students.

Research within interprofessional education (IPE) indicates health professional students hold stereotypes of other health professions at all stages within their academic journey. IPE can minimize negative stereotypes and influence a student's willingness and readiness to collaborate with others. This article explores undergraduate pre-health student stereotypes of various health professionals at the beginning and end of a six-week summer academic enrichment program, which included IPE. Convenience sampling was used to request participation in a survey, which included the Student Stereotypes Ratings Questionnaire (SSRQ). The SSRQ asks students to rate their perception of health professions on multiple traits. One hundred pre-health students across three institutions completed the SSRQ. The mean scores across all professions and all traits increased post-survey. Lowest pre-mean scores were for nursing (the ability to work independently and the ability to lead a team) and registered dietitian (the ability to lead a team). The highest pre-mean score was for the physician profession for academic ability. Results from this study indicate varying levels of stereotypes have already developed in pre-health students. After the six-week program, pre-health students' perceptions of health professions were positively affected. Data from this study indicates there are benefits to exposing pre-health students to IPE.

Preparing Students for a More Public Health-Aware Market in Response to COVID-19.

The COVID-19 pandemic has made the public more aware of public health and the role its professionals play in addressing the pandemic. Schools and programs in public health have a new opportunity to recruit, train, and sustain the public health workforce. Academic public health can further educate the public and prepare students for meaningful careers through interprofessional education and practice-based learning.

Biosolids and sludge management.

The review is organized in sections including regulatory developments and market analysis; analysis and quantification of characteristics including microconstituents and metals; treatment advances for the conversion of sludge to biosolids including pretreatment and sludge minimization, conditioning and dewatering, digestion, composting, and innovative technologies; product development and reuse including adsorbents and thermal products, agricultural and other uses, and innovative uses; odor and air emissions; and energy factors. PRACTITIONER POINTS: Summary of advances in the field of residuals and biosolids research in 2018. This review outlines the major contributions of researchers that have been published in peer-reviewed journals and conference proceedings. Topics covered range from regulation to innovation.

Supporting Health System Transformation: The development of an integrated interprofessional curriculum inclusive of public health students.

Under pressures to support health system transformation, many health professional accreditation organizations have incorporated standards requiring interprofessional education. However, the inclusion of population health topics and public health or health administration students into IPE experiences is limited. With the belief that understanding and cooperation among the health professions will be important to support health system transformation, The Louisiana State University Health Sciences Center-New Orleans has created several IPE experiences focused on population health, programs that are examined in this article along with insights that could prove useful for other programs seeking to build IPE into their regular curricula.

Biosolids and Sludge Management.

Aligning interprofessional education collaborative sub-competencies to a progression of learning.

In the United States, the Interprofessional Education Collaborative (IPEC) developed four core competencies for interprofessional collaborative practice. Even though the IPEC competencies and respective sub-competencies were not created in a hierarchal manner, one might reflect upon a logical progression of learning as well as learners accruing skills allowing them to master one level of learning and building on the aggregate of skills before advancing to the next level. The Louisiana State University Health-New Orleans Center for Interprofessional Education and Collaborative Practice (CIPECP) determined the need to align the sub-competencies with the level of behavioural expectations in order to simplify the process of developing an interprofessional education experience targeted to specific learning levels. In order to determine the most effective alignment, CIPECP discussions revolved around current programmatic expectations across the institution. Faculty recognised the need to align sub-competencies with student learning objectives. Simultaneously, a progression of learning existing within each of the four IPEC domains was noted. Ultimately, the faculty and staff team agreed upon categorising the sub-competencies in a hierarchical manner for the four domains into either a "basic, intermediate, or advanced" level of competency.
