- Noise from city traffic is one of the most significant environmental stressors. Natural soundscapes, such as bird songs, have been suggested to potentially mitigate or mask noise. All previous studies on masking noise use self-evaluation data rather than physiological data. In this study, while respondents (n = 117) watched a 360 degrees virtual reality (VR) photograph of a park, they were exposed to different soundscapes and mild electrical shocks. The soundscapesbird song, bird song and traffic noise, and traffic noisewere played during a 10 min recovery period while their skin conductance levels were assessed as a measure of arousal/stress. No significant difference in stress recovery was found between the soundscapes although a tendency for less stress in bird song and more stress in traffic noise was noted. All three soundscapes, however, significantly reduced stress. This result could be attributed to the stress-reducing effect of the visual VR environment, to the noise levels being higher than 47 dBA (a level known to make masking ineffective), or to the respondents finding bird songs stressful. Reduction of stress in cities using masking with natural sounds requires further studies with not only larger samples but also sufficient methods to detect potential sex differences.

- Due to the climate change, vegetation of tundra ecosystems is predicted to shift toward shrub and tree dominance, and this change may influence bryophytes. To estimate how changes in growing environment and the dominance of vascular plants influence bryophyte abundance, we compared the relationship of occurrence of bryophytes among other plant types in a five-year experiment of warming (T), fertilization (F) and T + F in two vegetation types, heath and meadow, in a subarctic–alpine ecosystem. We compared individual leaf area among shrub species to confirm that deciduous shrubs might cause severe shading effect. Effects of neighboring functional types on the performance of Hylocomium splendens was also analyzed. Results show that F and T + F treatments significantly influenced bryophyte abundance negatively. Under natural conditions, bryophytes in the heath site were negatively related to the abundance of shrubs and lichens and the relationship between lichens and bryophytes strengthened after the experimental period. After five years of experimental treatments in the meadow, a positive abundance relationship emerged between bryophytes and deciduous shrubs, evergreen shrubs and forbs. This relationship was not found in the heath site. Our study therefore shows that the abundance relationships between bryophytes and plants in two vegetation types within the same area can be different. Deciduous shrubs had larger leaf area than evergreen shrubs but did not show any shading effect on H. splendens.

- Tobacco smoking is a risk factor for numerous disorders, including cancers affecting organs outside the respiratory tract. Epidemiological data suggest that smoking is a greater risk factor for these cancers in males compared to females. This observation, together with the fact that males have a higher incidence of and mortality from most non-sex-specific cancers, remains unexplained. Loss of chromosome Y (LOY) in blood cells is associated with increased risk of nonhematological tumors. We demonstrate here that smoking is associated with LOY in blood cells in three independent cohorts [TwinGene: odds ratio (OR) = 4.3, 95% CI = 2.8-6.7; ULSAM: OR = 2.4, 95% CI = 1.6-3.6; and PIVUS: OR = 3.5, 95% CI = 1.4-8.4] encompassing a total of 6014 men. The data also suggest that smoking has a transient and dose-dependent mutagenic effect on LOY status. The finding that smoking induces LOY thus links a preventable risk factor with the most common acquired human mutation.

- Background: Advance care planning (ACP) is a process involving conversations about values and preferences regarding future care at the end-of-life. ACP has led to positive outcomes, both in relation to quality of life and with increased use of palliative care, less life-sustaining treatment and fewer hospital admissions. Sweden has yet to embrace the practice systematically, but scattered initiatives exist.Aim: To study implementation of a routine for ACP in NH settings in Sweden by exploring healthcare professionals’ experiences of engaging in ACP following this implementation.Methods: The study followed a qualitative inductive design with convenience and snowball sampling. Semi-structured group and individual interviews with registered healthcare professionals were analysed using qualitative content analysis.Findings: Organisational support for sustainable ACP implementation was found to be essential. This included sufficient training, facilitation, collaboration and uniform work routines across providers and professionals. Engaging in ACP conversations following the implemented routine was found to be a process of preparing, being, talking, deciding and sharing.Conclusions: Successful implementation of ACP in NHs requires a carefully planned implementation strategy. ACP in NHs tend to be medically focused at the expense of residents’ psychosocial care-planning needs. Widespread uptake of ACP in Sweden could be useful in the national effort to adopt more person-centred care in Swedish healthcare.KEY POINTS While advance care planning has been implemented in many other countries, Sweden lacks a national strategy on advance care planning and Swedish healthcare settings have yet to systematically implement this practice. • This study is the first to report on professionals’ experiences of engaging in sustainable advance care planning, following top-down implementation of the practice in one Swedish region. • Successful implementation of advance care planning in nursing homes requires a system-level approach, and shortcomings of the implementation process are highlighted.

- INTRODUCTION: Since early 2020, the COVID-19 pandemic has challenged societies and revealed the built-in fragility and dependencies in complex adaptive systems, such as healthcare. The pandemic has placed healthcare providers and systems under unprecedented amounts of strain with potential consequences that have not yet been fully elucidated. This multilevel project aims to explore resilient performance with the purpose of improving the understanding of how healthcare has adapted during the pandemic's rampage, the processes involved and the consequences on working conditions, ethics and patient safety.METHODS: An emerging explorative multilevel design based on grounded theory methodology is applied. Open and theoretical sampling is performed. Empirical data are gathered over time from written narratives and qualitative interviews with staff with different positions in healthcare organisations in two Swedish regions. The participants' first-person stories are complemented with data from the healthcare organisations' internal documents and national and international official documents.ANALYSIS: Experiences and expressions of resilient performance at different system levels and times, existing influencing risk and success factors at the microlevels, mesolevels and macrolevels and inter-relationships and consequences in different healthcare contexts, are explored using constant comparative analysis. Finally, the data are complemented with the current literature to develop a substantive theory of resilient performance during the pandemic.ETHICS AND DISSEMINATION: This project is ethically approved and recognises the ongoing strain on the healthcare system when gathering data. The ongoing pandemic provides unique possibilities to study system-wide adaptive capacity across different system levels and times, which can create an important basis for designing interventions focusing on preparedness to manage current and future challenges in healthcare. Feedback is provided to the settings to enable pressing improvements. The findings will also be disseminated through scientific journals and conferences.

- Background: Knowledge concerning nursing students' experiences of the clinical learning environment and how supervision is carried out is largely lacking. This study compares nursing students' perceptions of the clinical learning environment and supervision in two different supervision models: peer learning in student-dedicated units, with students working together in pairs and supervised by a "preceptor of the day" (model A), and traditional supervision, in which each student is assigned to a personal preceptor (model B). Methods: The study was performed within the nursing programme at a university college in Sweden during students' clinical placements (semesters 3 and 4) in medical and surgical departments at three different hospitals. Data was collected using the Clinical Learning Environment, Supervision and Nurse Teacher evaluation scale, CLES+T, an instrument tested for reliability and validity, and a second instrument developed for this study to obtain deeper information regarding how students experienced the organisation and content of the supervision. Independent t-tests were used for continuous variables, Mann-Whitney U-tests for ordinal variables, and the chi-square or Fischer's exact tests for categorical variables. Results: Overall, the students had positive experiences of the clinical learning environment and supervision in both supervision models. Students supervised in model A had more positive experiences of the cooperation and relationship between student, preceptor, and nurse teacher, and more often than students in model B felt that the ward had an explicit model for supervising students. Students in model A were more positive to having more than one preceptor and felt that this contributed to the assessment of their learning outcomes. Conclusions: A good learning environment for students in clinical placements is dependent on an explicit structure for receiving students, a pedagogical atmosphere where staff take an interest in supervision of students and are easy to approach, and engagement among and collaboration between preceptors and nurse teachers. This study also indicates that supervision based on peer learning in student-dedicated rooms with many preceptors can be more satisfying for students than a model where each student is assigned to a single preceptor.

Oxygenation and Hemodynamics Do Not Underlie Early Muscle Fatigue for Patients with Work-Related Muscle Pain

Tidskriftsartikel (refereegranskat)abstract
- Patients suffering from work-related muscle pain (WRMP) fatigue earlier during exercise than healthy controls. Inadequate oxygen consumption and/ or inadequate blood supply can influence the ability of the muscles to withstand fatigue. However, it remains unknown if oxygenation and hemodynamics are associated with early fatigue in muscles of WRMP patients. In the present study we applied near-infrared spectroscopy (NIRS) on the extensor carpi radialis (ECR) and trapezius (TD) muscles of patients with WRMP (n = 18) and healthy controls (n = 17). Our objective was to determine if there were group differences in endurance times for a low-level contraction of 15% maximal voluntary contraction (MVC) -sustained for 12-13 min, and to see if these differences were associated with differences in muscle oxygenation and hemodynamics. At baseline, oxygen saturation (StO(2)%) was similar between groups for the ECR, but StO2% was significantly lower for TD for the WRMP patients (76%) compared to controls (85%) (P < 0.01). Also, baseline ECR blood flow was similar in the two groups. For both muscles there were a larger number of patients, compared to controls, that did not maintain the 15% MVC for the allotted time. Consequently, the endurance times were significantly shorter for the WRMP patients than controls (medians, ECR: 347 s vs. 582 s; TD: 430 s vs. 723 s respectively). Responses in StO(2)% during the contractions were not significantly different between groups for either muscle, i.e. no apparent difference in oxygen consumption. Overall, we interpret our findings to indicate that the early fatigue for our WRMP patients was not associated with muscle oxygenation and hemodynamics.
