The role of mindfulness in stress, productivity and wellbeing of foundation year doctors: a mixed-methods feasibility study of the mindful resilience and effectiveness training programme.

BACKGROUND: Medical Foundation Year (FY) doctors demonstrate greater psychological distress compared with the general population and other student groups. This feasibility study investigated FY doctors' perceptions of mindfulness and the impact of a mindful resilience and effectiveness training (MRET) programme on stress, wellbeing, and performance. METHODS: Mixed-methods study utilising a questionnaire (study 1, N = 144) and a pre-post analysis design of MRET programme (study 2, N = 13), along with focus groups (N = 7). RESULTS: In study 1 28.5% of FY's reported using mindfulness. All five mindfulness facets were significantly, and positively, associated with mental wellbeing (p < 0.05). Acting with awareness (AA) and non-reactivity (NR) were significantly, positively associated with a challenge responses to stress (p < 0.05). Threat and loss appraisals were negatively associated with AA, NR, and non-judging (p < 0.01). Perceived productivity was positively associated with mindfulness facets: describing, AA, and NR (p < 0.001). In study 2, there were significant increases in wellbeing and mindfulness facets observing, describing, AA, and NR, and threat appraisals decreased (p < 0.05). The main themes identified across the focus group included Reframed Mindset, Values-Based Action, Embodied Leadership and Pedagogy. CONCLUSIONS: There exists a relationship between mindfulness, psychological wellbeing, and performance in FYs. The MRET prorgamme improved psychological wellbeing and reduced threat appraisals. Future work could focus resources on enhancing the skills of AA and NR, as this may be sufficient to bring about meaningful improvements in wellbeing, percieved productivity and cognitive reappraisal of stressful life events.

Light and flow regimes regulate the metabolism of rivers.

Mean annual temperature and mean annual precipitation drive much of the variation in productivity across Earth's terrestrial ecosystems but do not explain variation in gross primary productivity (GPP) or ecosystem respiration (ER) in flowing waters. We document substantial variation in the magnitude and seasonality of GPP and ER across 222 US rivers. In contrast to their terrestrial counterparts, most river ecosystems respire far more carbon than they fix and have less pronounced and consistent seasonality in their metabolic rates. We find that variation in annual solar energy inputs and stability of flows are the primary drivers of GPP and ER across rivers. A classification schema based on these drivers advances river science and informs management.

Impact of changed positive and negative task-related brain activity on word-retrieval in aging.

Previous functional imaging studies that compared activity patterns in older and younger adults during nonlinguistic tasks found evidence for 2 phenomena: older participants usually show more pronounced task-related positive activity in the brain hemisphere that is not dominant for the task and less pronounced negative task-related activity in temporo-parietal and midline brain regions. The combined effects of these phenomena and the impact on word retrieval, however, have not yet been assessed. We used functional magnetic resonance imaging to explore task-related positive (active task > baseline) and negative activity (baseline > active task) during semantic and phonemic verbal fluency tasks. Increased right frontal positive activity during the semantic task and reduced negative activity in the right hemisphere during both tasks was associated with reduced performance in older subjects. No substantial relationship between changes in positive and negative activity was observed in the older participants, pointing toward 2 partially independent but potentially co-occurring processes. Underlying causes of the observed functional network inefficiency during word retrieval in older adults need to be determined in the future.
