Community involvement in addressing the antibiotic crisis

Increasing student interest and success in STEM education is a top priority for many postsecondary educational institutions. One well-documented approach to both priorities is to have students participate in a Course Undergraduate Research Experience (CURE). Faculty from several technical colleges and universities in Wisconsin teamed up with the Tiny Earth organization to offer a CURE to address the search for new antibiotics. Students enrolled in undergraduate microbiology courses engaged in research and participated in community outreach. To involve the community, faculty from various institutions joined an NFL team, the Green Bay Packers, and created the Tiny Earth in Titletown symposium. Here, students presented their work via scientific posters, to community and industry members, and networked with other scientists from around the region. The Tiny Earth in Titletown symposium started in 2018, was held again in 2019, and returned in 2022 following a 2-year hiatus due to the COVID-19 pandemic. Record attendance in 2022 suggests that community outreach and education may be helping restore trust in science that was lost during the pandemic.

Performance Against WELCOA’s Worksite Health Promotion Benchmarks Across Years Among Selected US Organizations

Purpose:

The purpose of this study was to quantify the performance of organizations’ worksite health promotion (WHP) activities against the benchmarking criteria included in the Well Workplace Checklist (WWC).

Design:

The Wellness Council of America (WELCOA) developed a tool to assess WHP with its 100-item WWC, which represents WELCOA’s 7 performance benchmarks.

Setting:

Workplaces.

Participants:

This study includes a convenience sample of organizations who completed the checklist from 2008 to 2015. The sample size was 4643 entries from US organizations.

Measures:

The WWC includes demographic questions, general questions about WHP programs, and scales to measure the performance against the WELCOA 7 benchmarks.

Analysis:

Descriptive analyses of WWC items were completed separately for each year of the study period.

Results:

The majority of the organizations represented each year were multisite, multishift, medium- to large-sized companies mostly in the services industry. Despite yearly changes in participating organizations, results across the WELCOA 7 benchmark scores were consistent year to year. Across all years, benchmarks that organizations performed the lowest were senior-level support, data collection, and programming; wellness teams and supportive environments were the highest scoring benchmarks.

Conclusion:

In an era marked with economic swings and health-care reform, it appears that organizations are staying consistent in their performance across these benchmarks. The WWC could be useful for organizations, practitioners, and researchers in assessing the quality of WHP programs.

MtrC, an outer membrane decahaem c cytochrome required for metal reduction in Shewanella putrefaciens MR-1

Shewanella putrefaciens is a facultative anaerobe that can use metal oxides as terminal electron acceptors during anaerobic respiration. Two proteins, MtrB and Cct, have been identified that are specifically involved in metal reduction. Analysis of S. putrefaciens mutants deficient in metal reduction led to the identification of two additional proteins that are involved in this process. MtrA is a periplasmic decahaem c-type cytochrome that appears to be part of the electron transport chain, which leads to Fe(III) and Mn(IV) reduction. MtrC is an outer membrane decahaem c-type cytochrome that appears to be required for the activity of the terminal Fe(III) reductase. Membrane fractions of mutants deficient in MtrC exhibited a decreased level of Fe(III) reduction compared with the wild type. We suggest that MtrC may be a component of the terminal reductase or may be required for its assembly.
