Environmental cleaning is essential to patient and health worker safety, yet it is a substantially neglected area in terms of knowledge, practice, and capacity-building, especially in resource-limited settings. Public health advocacy, research and investment are urgently needed to develop and implement cost-effective interventions to improve environmental cleanliness and, thus, overall healthcare quality and safety. We outline here the CLEAN Group Consensus exercise yielding twelve urgent research questions, grouped into four thematic areas: standards, system strengthening, behaviour change, and innovation.

NIOSH researchers are pioneering the study of musculoskeletal health as professional ergonomists. We examine physical and social components of work environments to mitigate musculoskeletal injury risks. Part of our mission is to reduce the burden of work-related musculoskeletal disorders (MSDs) through a focused program of research and prevention that protects workers from MSDs, helps management mitigate related risks and liabilities, and helps practitioners improve the efficacy of workplace interventions. The purpose of this discussion panel is to disseminate research findings and recommendations (1) to practitioners to interpret and apply the results of research to real-world problems, and (2) to inspire researchers to continue their efforts to protect the millions of workers at risk. © 2023 Human Factors and Ergonomics Society.

OBJECTIVE: To assess effects on breast cancer risk of exposure to both oral contraceptives and menopausal hormones, an increasingly common exposure. DESIGN: A case-control study of breast cancer among women under the age of 55 years in Atlanta, GA involving 1,031 cases and 919 population controls was conducted. RESULTS: Ever use of oral contraceptives was associated with a relative risk of 1.1 (95% 0.9-1.4), whereas the relative risk for hormone replacement therapy was 0.9 (95% CI 0.7-1.2). Seventeen percent of the cases versus 19% of the population controls reported exposure to both agents, resulting in a relative risk of 1.0 (95% CI 0.7-1.4) relative to those unexposed to either preparation. Although there was little variation in risk associated with joint effects by either age or race, there were statistically nonsignificant elevations in risk for this exposure among women who had experienced a natural menopause (relative risk = 2.0, 95% CI 0.7-5.6), were relatively thin (relative risk = 1.5, 0.8-3.0), or who had a first degree relative with breast cancer (relative risk = 2.0, 0.6-7.0). When joint effects of longer term use of both agents were considered, subjects who reported use of oral contraceptives for 10 or more years and hormone replacement for 3 or more years had a relative risk of 3.2 (95% CI 1.4-7.4) compared with nonusers of either preparation. CONCLUSIONS: Although our results must be cautiously interpreted given small numbers within subgroups, they raise concern and emphasize the need for further evaluation on breast cancer risk of the increasingly common exposure to both oral contraceptives and hormone replacement therapy.

PURPOSE: Using the Internet to meet new people is becoming more common; however, such behavior is often considered risky, particularly for adolescents. Nevertheless, adolescents are meeting people through online venues and some are forming romantic/sexual relationships. The purpose of this study was to examine the relationship and sexual satisfaction reported by teens in online- and offline-initiated relationships. METHODS: Data were collected from 273 13-19 year olds visiting a publicly funded clinic through 2010 and 2011. Questions included where respondents met the partner (online vs. offline), time between meeting and first sex, how well they knew the partner, and relationship and sexual (R&S) satisfaction. Analyses consisted of descriptive statistics, t tests, and path analysis, exploring R&S satisfaction in online- and offline-initiated relationships. RESULTS: R&S satisfaction scores were moderate for adolescents who reported meeting partners online and in person but were statistically higher in offline-initiated relationships. There was an inverse relationship between having an online partner and both relationship and sexual satisfaction. Additionally, knowing partners for a longer period of time and feeling more knowledgeable about partners before having sex were statistically significantly related to higher R&S satisfaction. CONCLUSIONS: Teens in this study reported more satisfying relationships with partners met offline compared with online. Results suggest that encouraging teens to wait longer and to get to know their partner(s) better before engaging in sex may improve satisfaction with, and quality of, those relationships. These findings provide an important contribution to sexual health promotion among young people, with whom technology use is ubiquitous.
