- Introduction Almost 60% of antibiotics in frail elderly are prescribed for alleged urinary tract infections (UTIs). A substantial part of this comprises prescriptions in case of non-specific symptoms or asymptomatic bacteriuria, for which the latest guidelines promote restrictiveness with antibiotics. We aim to reduce inappropriate antibiotic use for UTIs through an antibiotic stewardship intervention (ASI) that encourages to prescribe according to these guidelines. To develop an effective ASI, we first need a better understanding of the complex decision-making process concerning suspected UTIs in frail elderly. Moreover, the implementation approach requires tailoring to the heterogeneous elderly care setting. Methods and analysis First, we conduct a qualitative study to explore factors contributing to antibiotic prescribing for UTIs in frail elderly, using semi-structured interviews with general practitioners, nursing staff, patients and informal caregivers. Next, we perform a pragmatic cluster randomised controlled trial in elderly care organisations. A multifaceted ASI is implemented in the intervention group; the control group receives care as usual. The ASI is centred around a decision tool that promotes restrictive antibiotic use, supported by a toolbox with educational materials. For the implementation, we use a modified participatory-action-research approach, guided by the results of the qualitative study. The primary outcome is the number of antibiotic prescriptions for suspected UTIs. We aim to recruit 34 clusters with in total 680 frail elderly residents >= 70 years. Data collection takes place during a 5-month baseline period and a 7-month follow-up period. Finally, we perform a process evaluation. The study has been delayed for 6 months due to COVID-19 and is expected to end in July 2021. Ethics and dissemination Ethical approvals and/or waivers were obtained from the ethical committees in Poland, the Netherlands, Norway and Sweden. The results will be disseminated through publication in peer-reviewed journals and conference presentations.

- Background a suspected urinary tract infection (UTI) is the most common reason to prescribe antibiotics in a frail older patient. Frequently, antibiotics are prescribed unnecessarily. To increase appropriate antibiotic use for UTIs through antibiotic stewardship interventions, we need to thoroughly understand the factors that contribute to these prescribing decisions. Objectives (1) to obtain insight into factors contributing to antibiotic prescribing for suspected UTIs in frail older adults. (2) To develop an overarching model integrating these factors to guide the development of antibiotic stewardship interventions for UTIs in frail older adults. Methods we conducted an exploratory qualitative study with 61 semi-structured interviews in older adult care settings in Poland, the Netherlands, Norway and Sweden. We interviewed physicians, nursing staff, patients and informal caregivers. Results participants described a chain of decisions by patients, caregivers and/or nursing staff preceding the ultimate decision to prescribe antibiotics by the physician. We identified five themes of influence: (1) the clinical situation and its complexity within the frail older patient, (2) diagnostic factors, such as asymptomatic bacteriuria, (3) knowledge (gaps) and attitude, (4) communication: interprofessional, and with patients and relatives and (5) context and organisation of care, including factors such as availability of antibiotics (over the counter), antibiotic stewardship efforts and factors concerning out-of-hours care. Conclusions decision-making on suspected UTIs in frail older adults is a complex, multifactorial process. Due to the diverse international setting and stakeholder variety, we were able to provide a comprehensive overview of factors to guide the development of antibiotic stewardship interventions.

Tidskriftsartikel (refereegranskat)abstract
- Current analyses and predictions of spatially explicit patterns and processes in ecology most often rely on climate data interpolated from standardized weather stations. This interpolated climate data represents long-term average thermal conditions at coarse spatial resolutions only. Hence, many climate-forcing factors that operate at fine spatiotemporal resolutions are overlooked. This is particularly important in relation to effects of observation height (e.g. vegetation, snow and soil characteristics) and in habitats varying in their exposure to radiation, moisture and wind (e.g. topography, radiative forcing or cold-air pooling). Since organisms living close to the ground relate more strongly to these microclimatic conditions than to free-air temperatures, microclimatic ground and near-surface data are needed to provide realistic forecasts of the fate of such organisms under anthropogenic climate change, as well as of the functioning of the ecosystems they live in. To fill this critical gap, we highlight a call for temperature time series submissions to SoilTemp, a geospatial database initiative compiling soil and near-surface temperature data from all over the world. Currently, this database contains time series from 7,538 temperature sensors from 51 countries across all key biomes. The database will pave the way toward an improved global understanding of microclimate and bridge the gap between the available climate data and the climate at fine spatiotemporal resolutions relevant to most organisms and ecosystem processes.

Greater temperature sensitivity of plant phenology at colder sites: implications for convergence across northern latitudes
- 2017

Tidskriftsartikel (refereegranskat)abstract
- Warmer temperatures are accelerating the phenology of organisms around the world. Temperature sensitivity of phenology might be greater in colder, higher latitude sites than in warmer regions, in part because small changes in temperature constitute greater relative changes in thermal balance at colder sites. To test this hypothesis, we examined up to 20 years of phenology data for 47 tundra plant species at 18 high-latitude sites along a climatic gradient. Across all species, the timing of leaf emergence and flowering was more sensitive to a given increase in summer temperature at colder than warmer high-latitude locations. A similar pattern was seen over time for the flowering phenology of a widespread species, Cassiope tetragona. These are among the first results highlighting differential phenological responses of plants across a climatic gradient and suggest the possibility of convergence in flowering times and therefore an increase in gene flow across latitudes as the climate warms.

Forskningsöversikt (refereegranskat)abstract
- At the close of the Fourth International Polar Year, we take stock of the ecological consequences of recent climate change in the Arctic, focusing on effects at population, community, and ecosystem scales. Despite the buffering effect of landscape heterogeneity, Arctic ecosystems and the trophic relationships that structure them have been severely perturbed. These rapid changes may be a bellwether of changes to come at lower latitudes and have the potential to affect ecosystem services related to natural resources, food production, climate regulation, and cultural integrity. We highlight areas of ecological research that deserve priority as the Arctic continues to warm.

- Advancing phenology is one of the most visible effects of climate change on plant communities, and has been especially pronounced in temperature-limited tundra ecosystems. However, phenological responses have been shown to differ greatly between species, with some species shifting phenology more than others. We analysed a database of 42,689 tundra plant phenological observations to show that warmer temperatures are leading to a contraction of community-level flowering seasons in tundra ecosystems due to a greater advancement in the flowering times of late-flowering species than early-flowering species. Shorter flowering seasons with a changing climate have the potential to alter trophic interactions in tundra ecosystems. Interestingly, these findings differ from those of warmer ecosystems, where early-flowering species have been found to be more sensitive to temperature change, suggesting that community-level phenological responses to warming can vary greatly between biomes.

Tidskriftsartikel (refereegranskat)abstract
- Snow is an important driver of ecosystem processes in cold biomes. Snow accumulation determines ground temperature, light conditions, and moisture availability during winter. It also affects the growing season's start and end, and plant access to moisture and nutrients. Here, we review the current knowledge of the snow cover's role for vegetation, plant-animal interactions, permafrost conditions, microbial processes, and biogeochemical cycling. We also compare studies of natural snow gradients with snow experimental manipulation studies to assess time scale difference of these approaches. The number of tundra snow studies has increased considerably in recent years, yet we still lack a comprehensive overview of how altered snow conditions will affect these ecosystems. Specifically, we found a mismatch in the timing of snowmelt when comparing studies of natural snow gradients with snow manipulations. We found that snowmelt timing achieved by snow addition and snow removal manipulations (average 7.9 days advance and 5.5 days delay, respectively) were substantially lower than the temporal variation over natural spatial gradients within a given year (mean range 56 days) or among years (mean range 32 days). Differences between snow study approaches need to be accounted for when projecting snow dynamics and their impact on ecosystems in future climates.

Tidskriftsartikel (refereegranskat)abstract
- BackgroundPrimary care is a critical partner for antimicrobial stewardship efforts given its high human antibiotic usage. Peer comparison audit and feedback (A & F) is often used to reduce inappropriate antibiotic prescribing. The design and implementation of A & F may impact its effectiveness. There are no best practice guidelines for peer comparison A & F in antibiotic prescribing in primary care.ObjectiveTo develop best practice guidelines for peer comparison A & F for antibiotic prescribing in primary care in high income countries by leveraging international expertise via the Joint Programming Initiative on Antimicrobial Resistance-Primary Care Antibiotic Audit and Feedback Network.MethodsWe used a modified Delphi process to achieve convergence of expert opinions on best practice statements for peer comparison A & F based on existing evidence and theory. Three rounds were performed, each with online surveys and virtual meetings to enable discussion and rating of each best practice statement. A five-point Likert scale was used to rate consensus with a median threshold score of 4 to indicate a consensus statement.ResultsThe final set of guidelines include 13 best practice statements in four categories: general considerations (n = 3), selecting feedback recipients (n = 1), data and indicator selection (n = 4), and feedback delivery (n = 5).ConclusionWe report an expert-derived best practice recommendations for designing and evaluating peer comparison A & F for antibiotic prescribing in primary care. These 13 statements can be used by A & F designers to optimize the impact of their quality improvement interventions, and improve antibiotic prescribing in primary care.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Background: Researchers and policymakers have acknowledged sports clubs (SCs) as health promoting settings. Limited research links the health promoting sports club (HPSC) concept with evidence-driven strategies to offer SCs guidance to develop health promotion interventions. As implementation science insists on theoretically grounded interventions, this work’s objective was to provide SCs an evidence-driven intervention framework for planning health promotions.Methods: A 4-step process was undertaken: 1) investigate indicators for SCs to be considered health promoting, 2) adapt the theoretical HPSC concept to create a HPSC model, 3) reformulate published evidence-driven guidelines into imple-mentable intervention components (ICs) and 4) merge the model with the ICs to provide an intervention planning framework for SCs. During 3 workshops, researchers defined the model elements and ICs. Workshop participants classified ICs into the HSPC model. Each IC could be classified multiple times within the model.Results:Researchers drafted 5 HPSC indicators: 1) an approach embracing all SC actions, 2) involve all SC levels in actions and decisions, 3) involve external partners, 4) promoting health is continuous and iterative and 5) base actions on needs. To create the HPSC model, elements were defined: 3 SC levels (club, management, coaches) and 4 health determinants (organizational, social, environmental, economic) per level based on the indicators. Published guidelines from literature reviews aided in developing 14 strategies with 55 ICs. Workshop classification of ICs into the model included: club (n = 79), management (n = 67) and coaches (n = 48).Conclusions: The theoretical HPSC model and intervention planningframework act as starting points to develop and implementinterventions to increase HP efforts by stakeholders in severalways: 1) SCs can apply strategies based on goals, 2) SCs cantarget specific levels with corresponding ICs or 3) ICs cantarget specific health determinants.Key messages:A Health Promoting Sports Club model defines 4 health determinants at 3 levels (coach, management operational) of sports clubs to plan, develop and implement targeted health promotion activities.This HPSC intervention planning framework has 14 strategies with 55 intervention components targeting multiple sports club levels giving stakeholders a path to become a health promoting sports club.

Tidskriftsartikel (refereegranskat)abstract
- Background: The settings-based approach has become an increasing focus in health promotion since the World Health Organization’s 1986 Ottawa Charter. Schools and cities have implemented this approach, but development within sports clubs is limited. Thus, an internationally validated measurement of health promotion within this setting is lacking.Methods: A modified Delphi study was completed to develop an international evaluation tool grounded in the settings-based approach. Expert panelists from academia, sports and health sectors were invited to participate in 3 online rounds. Items were generated or selected based on 3 prior Delphi-based studies and 2 nationally validated scales. Round one created a collaborative list of items, round two validated items based on relevance, importance and feasibility and the final round classified items into one of four determinants: cultural, social, environmental or economic.Results: Panelists (69) from 13 countries participated in creating a final list of 62 items at 3 organizational levels. The sports club level included; 5 cultural, 6 social, 6 environmental and 5 economic items. The management level included; 5 cultural, 5 social, 5 environmental and 3 economic items. The coaching level included; 5 cultural, 5 social, 4 environmental and 4 economic items.Conclusions: This study provides three important innovations; 1- it is rooted in theory through the settings-based approach, 2- the measurement tool includes three levels within sports clubs, capturing a whole club dynamic and 3- all items included in the tool have been validated by an international panel of experts.Key messages:This 62-item measurement tool allows the comparison of perceptions from participants, coaches and management regarding how health is promoted within their sports club.This information offers insight on the capacity of sports clubs to implement and monitor policies and practices on the promotion of health beyond sports performance within their organization.

- The potential for organised sports to promote health has been underexploited so far, according to researchers and policy-makers. Sports clubs have limited capacity to promote health due to their voluntary nature and have called for support from their national sports federations. The present article provides guidelines based on health promoting sports clubs theoretical foundations, and an analysis of practical tools and proven strategies to support national sports federations’ investment in health promotion (HP). A qualitative iterative study was undertaken, based on five two-hour meetings of a group of 15 international researchers in health promotion in sports clubs. Notes and minutes from meetings, as well as shared outputs were analyzed based on the health promoting sports club framework. Guidelines for national sports federations to promote health includes a definition of a health promoting sports federation, a description of the settings-based approach stages adapted to national sports federations, as well as practical applications of the health promoting sports club's intervention strategies. The analysis of existing tools demonstrated that most tools are centered on a single dimension of health (social, mental, physical, spiritual or community), and often on a specific health topic. Furthermore, they do not cover HP as a continuous process or support of sports clubs’ members health, but are generally short-term programs. The HPSF clarifies theoretical concepts, their practical implementation via case studies and outlines intervention components and tools useful for sports federations in their implementation of HP. The guidelines are meant to facilitate national sports federations to acknowledge, reinforce and foster their further investment in HP.

- Background: The importance of resilience factors in the positive adaptation of refugee youth is widely recognised. However, their actual mechanism of impact remains under-researched. The aim of this study was therefore to explore protective and promotive resilience mechanisms on both negative and positive mental health outcomes. Promotive resilience is seen as a direct main effect and protective resilience as a moderating effect.Methods: Cross-sectional study with 160 Syrian youth aged 13-24 years, who recently resettled in Norway. A multi-dimensional measure for resilience was used to explore the potential impact of resilience factors on pathways between potentially traumatic events from war and flight (PTE), post-migration stress, mental distress and health-related quality of life (HRQoL). Analyses included regression, moderation and moderated mediation using the PROCESS macro for SPSS.Results: A direct main effect of resilience factors (promotive resilience mechanism) was found for HRQoL and general mental distress, but not for post-traumatic stress disorder (PTSD). No moderating effects of resilience factors (protective resilience mechanism) were found. Post-migration stressors mediated the effects of PTE, and this indirect effect was present at all levels of resilience. Relational and environmental level resilience factors and combined amounts had more impact than individual level factors.Conclusions: Despite high risk exposure and mental distress, resilience was also high. The direct main effect of resilience factors and less impact on PTSD, suggests universal resilience building interventions may be beneficial, compared to exclusively targeting groups with high symptom levels. These interventions should target relational and environmental resilience factors as well as individual coping techniques. Additionally, reducing current stress and symptoms could increase the efficacy of resilience factors already present.

- Objective When the COVID-19 pandemic reached Norway, primary health care had to reorganize to ensure safe patient treatment and maintain infection control. General practitioners (GPs) are key health care providers in the municipalities. Our aim was to explore the experiences and management strategies of Norwegian GPs during the COVID-19 pandemic - over time, and in the context of a sudden organizational change. Design Longitudinal qualitative interview study with two interview rounds. The first round of interviews was conducted from September-December 2020, the second round from January-April 2021. In the first interview round, we performed eight semi-structured interviews with GPs from eight municipalities in Norway. In the second round, five of the GPs were re-interviewed. Consecutive interviews were performed 2-4 months apart. To analyze the data, we used thematic analysis. Results The COVID-19 pandemic required GPs to balance several concerns, such as continuity of care and their own professional efforts. Several GPs experienced challenges in the collaboration with the municipality and in relation to defining their own professional position. Guided by The Norwegian Association of General practitioners, The Norwegian College of General Practice and collegial support, they found viable solutions and ended up with a feeling of having adapted to a new normal. Conclusions Although our study demonstrates that the GPs adapted to the changing conditions, the current municipal health care models are not ideal. There is a need for clarification of responsibilities between GPs and the municipality to facilitate a more coordinated future pandemic response.

Tidskriftsartikel (refereegranskat)abstract
- Introduction Methenamine hippurate is a urinary antiseptic used as preventive treatment for recurrent urinary tract infections (UTIs) in some Scandinavian countries. However, the scientific evidence for the preventive effect and safety for longer-term use is limited. The aim of this study is to assess whether methenamine hippurate can reduce the incidence of UTIs in older women with recurrent UTIs. Methods and analysis The ImpresU consortium is a collaboration between Norway, Sweden, Poland and the Netherlands. The study is a randomised, controlled, triple-blind phase IV clinical trial. Women ≥70 years with recurrent UTIs are screened for eligibility in a general practice setting. We aim to include 400 women in total, with 100 recruited from each collaborating country. The participants are randomised to treatment with methenamine hippurate 1 g or placebo tablets two times per day for a treatment period of 6 months, followed by a drug-free follow-up period of 6 months. The primary outcome is number of antibiotic treatments for UTIs during the treatment period. The secondary outcomes include number of antibiotic treatments for UTIs during the follow-up period and self-reported symptom of severity and duration of UTI episodes. Differences in complications between the treatment groups are measured as safety outcomes. We also aim to investigate whether strain characteristics or phylogenetic subgroups of Escherichia coli present in the urine culture at inclusion have a modifying effect on the outcomes. Ethics and dissemination Ethical approvals are obtained in all participating countries. The results will be communicated in peer-reviewed journals and at scientific conferences. Trial registration number ClinicalTrials.gov Registry (NCT04077580); EudraCT: 2018-002235-15.

Tidskriftsartikel (refereegranskat)abstract
- Background Antibiotic overuse and misuse in primary care are common, highlighting the importance of antimicrobial stewardship (AMS) efforts in this setting. Audit and feedback (A&F) interventions can improve professional practice and performance in some settings. Objectives and methods To leverage the expertise from international members of the Joint Programming Initiative on Antimicrobial Resistance - Primary care Antibiotic Audit and feedback Network (JPIAMR-PAAN). Network members all have experience of designing and delivering A&F interventions to reduce inappropriate antibiotic prescribing in primary care settings. We aim to introduce the network and explore ongoing A&F activities in member regions. An online survey was administered to all network members to collect regional information. Results Fifteen respondents from 11 countries provided information on A&F activities in their country, and national/regional antibiotic stewardship programmes or policies. Most countries use electronic medical records as the primary data source, antibiotic appropriateness as the main outcome of feedback, and target GPs as the prescribers of interest. Funding sources varied across countries, which could influence the frequency and quality of A&F interventions. Nine out of 11 countries reported having a national antibiotic stewardship programme or policy, which aim to provide systematic support to ongoing AMS efforts and aid sustainability. Conclusions The survey identified gaps and opportunities for AMS efforts that include A&F across member countries in Europe, Canada and Australia. JPIAMR-PAAN will continue to leverage its members to produce best practice resources and toolkits for antibiotic A&F interventions in primary care settings and identify research priorities.

Tidskriftsartikel (refereegranskat)abstract
- A desmoplastic colorectal cancer stroma, characterized by excess turnover of the cancer-associated fibroblast derived collagens type III and VI, can lead to reduced drug-uptake and poor treatment response. We investigated the association between biomarkers of collagen type III and VI and overall survival (OS) in patients with metastatic colorectal cancer (mCRC). Serum samples were collected from 252 patients with mCRC prior to treatment with bevacizumab and chemotherapy. Serum concentrations of biomarkers reflecting formation of collagen type III (PRO-C3) and VI (PRO-C6) and degradation of collagen type VI (C6M and C6Mα3) were determined by ELISA. The biomarkers were evaluated for associations with OS, individually, combined, and after adjusting for carcinoembryonic antigen (CEA), lactate dehydrogenase (LDH) and performance status (PS). High baseline levels (> median) of each collagen biomarker were significantly associated with shorter OS (PRO-C3: HR = 2.0, 95%CI = 1.54–2.63; PRO-C6: HR = 1.6, 95%CI = 1.24–2.11; C6M: HR = 1.4, 95%CI = 1.05–1.78; C6Mα3: HR = 1.6, 95%CI = 1.16–2.07). PRO-C3 and PRO-C6 remained significant after adjustment for CEA, LDH and PS. Weak correlations were seen between the collagen biomarkers (r = 0.03–0.59) and combining all improved prognostic capacity (HR = 3.6, 95%CI = 2.30–5.76). Collagen biomarkers were predictive of shorter OS in patients with mCRC. This supports that collagen- and CAF biology is important in CRC.

- Key PointsQuestion When considering patients who have obstructive coronary artery disease and ischemia on stress testing, are there sex differences in severity of coronary artery disease, ischemia, and/or symptoms?Findings In this secondary analysis of the ISCHEMIA randomized clinical trial of 5179 patients, women had more frequent angina, less extensive coronary artery disease, and less severe ischemia than men. On multivariate analysis, female sex was independently associated with greater angina frequency.Meaning There may be inherent sex differences in the complex relationships between angina, ischemia, and atherosclerosis that may have implications for testing and treatment of patients with suspected coronary artery disease.AbstractImportance While many features of stable ischemic heart disease vary by sex, differences in ischemia, coronary anatomy, and symptoms by sex have not been investigated among patients with moderate or severe ischemia. The enrolled ISCHEMIA trial cohort that underwent coronary computed tomographic angiography (CCTA) was required to have obstructive coronary artery disease (CAD) for randomization.Objective To describe sex differences in stress testing, CCTA findings, and symptoms in ISCHEMIA trial participants.Design, Setting, and Participants This secondary analysis of the multicenter ISCHEMIA randomized clinical trial analyzed baseline characteristics of patients with stable ischemic heart disease. Individuals were enrolled from July 2012 to January 2018 based on local reading of moderate or severe ischemia on a stress test, after which blinded CCTA was performed in most. Core laboratories reviewed stress tests and CCTAs. Participants with no obstructive CAD or with left main CAD of 50% or greater were excluded. Those who met eligibility criteria including CCTA (if performed) were randomized to a routine invasive or a conservative management strategy (N = 5179). Angina was assessed using the Seattle Angina Questionnaire. Analysis began October 1, 2018.Interventions CCTA and angina assessment.Main Outcomes and Measures Sex differences in stress test, CCTA findings, and symptom severity.Results Of 8518 patients enrolled, 6256 (77%) were men. Women were more likely to have no obstructive CAD (<50% stenosis in all vessels on CCTA) (353 of 1022 [34.4%] vs 378 of 3353 [11.3%]). Of individuals who were randomized, women had more angina at baseline than men (median [interquartile range] Seattle Angina Questionnaire Angina Frequency score: 80 [70-100] vs 90 [70-100]). Women had less severe ischemia on stress imaging (383 of 919 [41.7%] vs 1361 of 2972 [45.9%] with severe ischemia; 386 of 919 [42.0%] vs 1215 of 2972 [40.9%] with moderate ischemia; and 150 of 919 [16.4%] vs 394 of 2972 [13.3%] with mild or no ischemia). Ischemia was similar by sex on exercise tolerance testing. Women had less extensive CAD on CCTA (205 of 568 women [36%] vs 1142 of 2418 men [47%] with 3-vessel disease; 184 of 568 women [32%] vs 754 of 2418 men [31%] with 2-vessel disease; and 178 of 568 women [31%] vs 519 of 2418 men [22%] with 1-vessel disease). Female sex was independently associated with greater angina frequency (odds ratio, 1.41; 95% CI, 1.13-1.76).Conclusions and Relevance Women in the ISCHEMIA trial had more frequent angina, independent of less extensive CAD, and less severe ischemia than men. These findings reflect inherent sex differences in the complex relationships between angina, atherosclerosis, and ischemia that may have implications for testing and treatment of patients with suspected stable ischemic heart disease.
