Changes in subjective stress experiences and self-efficacy beliefs of preschool teachers in Germany: A longitudinal study during 12 months of the COVID-19 pandemic.

This study collected monthly data between September 2020 and August 2021 to document the consequences of the COVID-19 pandemic for German preschool teachers during different pandemic phases. This longitudinal study investigated how subjective stress experiences and self-efficacy beliefs of preschool teachers (N = 279) change over time and explored associations on the inter- and intraindividual level. We observed phase-specific changes in subjective stress experiences and interindividual differences in change rates, but no systematic increase across the entire study period. Results also highlight self-efficacy beliefs as a resource for preschool teachers, which should be strengthened to better face stress experiences.

Climate change and occupational heat stress risks and adaptation strategies of mining workers: Perspectives of supervisors and other stakeholders in Ghana.

Increasing air temperatures as a result of climate change are worsening the impact of heat exposure on working populations, including mining workers, who are at risk of suffering heat-related illnesses, injury and death. However, inadequate awareness of climate change-related occupational heat stress risks and adaptation strategies have been shown to render occupational heat stress management ineffective. A concurrent mixed-methods approach was used to assess the perceptions of climate change and occupational heat stress risks and adaptation strategies of mining workers among supervisory personnel and other stakeholders in Ghana. Questionnaires and interviews were used to elicit data from 19 respondents. Data were processed and interpreted using descriptive statistics, chi-square and Fisher's exact tests, and thematic analysis. Supervisors' climate change risks perception was adequate, and their concern about workplace heat exposure risks was moderate. Mining workers' occupational heat stress risks experiences were linked to heat-related illness and minor injuries. Mining workers' adaptation strategies included water intake, use of cooling mechanisms, work-break practices, and clothing use. The related differences in job experience in the distribution of climate change risk perception and occupational heat stress risk experiences, and the difference in educational attainment in the distribution of adaptation strategies of occupational heat stress were significant (p < 0.05). Hence, an effective workplace heat management policy requires adequate understanding of occupational heat stress risks and adaptation policies and continued education and training for mining workers.

Development and Implementation of a Stress Monitoring Paradigm Using Virtual Reality Simulation During the COVID-19 Pandemic.

Healthcare providers, particularly during the COVID-19 crisis, have been forced to make difficult decisions and have reported acting in ways that are contrary to their moral values, integrity, and professional commitments, given the constraints in their work environments. Those actions and decisions may lead to healthcare providers' moral suffering and distress. This work outlines the development of the Moral Distress Virtual Reality Simulator (Moral Distress VRS) to research stress and moral distress among healthcare workers during the COVID-19 pandemic. The Moral Distress VRS was developed based on the agile methodology framework, with three simultaneous development streams. It followed a two-week sprint cycle, ending with meetings with stakeholders and subject matter experts, whereby the project requirements, scope, and features were revised, and feedback was provided on the prototypes until reaching the final prototype that was deployed for in-person study sessions. The final prototype had two user interfaces (UIs), one for the participant and one for the researcher, with voice narration and customizable character models wearing medical personal protective equipment, and followed a tree-based dialogue scenario, outputting a video recording of the session. The virtual environment replicated an ICU nursing station and a fully equipped patient room. We present the development process that guided this project, how different teams worked together and in parallel, and detail the decisions and outcomes in creating each major component within a limited deadline. Finally, we list the most significant challenges and difficulties faced and recommendations on how to solve them.

An Invisible Skin Marker for External Beam Radiation Therapy: Utilization of Ultraviolet Fluorescent Marker Pens.

Radiation therapy plays an important role in cancer treatment along with surgery and systemic therapy. The total dose of radiation therapy is divided into small doses, and the treatment is typically delivered once a day. The total treatment period can need several weeks or more, and it is necessary to deliver the radiation dose to the target volume within the patient precisely each time. Therefore, the reproducibility of patient positioning is essential for the precision of the dose delivery. Although radiological technologies such as image-guided radiation therapy have also recently been widely used for positioning patients, skin marking is still widely used in many facilities. Skin marking is an inexpensive and universal positioning technique in patients undergoing radiation therapy; however, it is considered a major source of psychological stress. We propose the use of fluorescent ink pens, which are invisible in standard room lighting, as skin markers for radiotherapy. The primary technique of fluorescence emission is widely employed in molecular biological experiments and for assessing cleaning protocols for infection control. This technique may reduce the stress induced by skin markings during radiotherapy.
