Pathways from research to sustainable development: Insights from ten research projects in sustainability and resilience.

Drawing on collective experience from ten collaborative research projects focused on the Global South, we identify three major challenges that impede the translation of research on sustainability and resilience into better-informed choices by individuals and policy-makers that in turn can support transformation to a sustainable future. The three challenges comprise: (i) converting knowledge produced during research projects into successful knowledge application; (ii) scaling up knowledge in time when research projects are short-term and potential impacts are long-term; and (iii) scaling up knowledge across space, from local research sites to larger-scale or even global impact. Some potential pathways for funding agencies to overcome these challenges include providing targeted prolonged funding for dissemination and outreach, and facilitating collaboration and coordination across different sites, research teams, and partner organizations. By systematically documenting these challenges, we hope to pave the way for further innovations in the research cycle.

Evaluation of selected organic fertilizers on conditioning soil health of smallholder households in Karagwe, Northwestern Tanzania.

Soil management is a strategy for improving soil suffering from problems such as low pH, nutrient deficiency, and erosion. The study evaluated the effects of human urine (HU), biogas slurry (BS), standard compost (StC), animal manure (AM), and synthetic fertilizer (SF) in comparison with no soil fertility management (NFM) on soil pH, cation exchange capacity (CEC), soil organic carbon (SOC), soil moisture content, nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), sodium (Na), copper (Cu), zinc (Zn), manganese (Mn), and iron (Fe) in the Karagwe district, a Northwestern Tanzania. Four household farms representing each soil amendment type were selected for soil sampling. A total of 192 soil samples were collected and air-dried. After laboratory analysis, BS-enriched soil had the highest pH (6.558), CEC (23.945 cmol+/kg), SOC (5.573%), soil moisture (5.573%), N (0.497%), P (247.130 mg/kg), K (3.036 cmol+/kg), Ca (18.983 cmol+/kg), Mg (4.076 cmol+/kg), Na (2.960 cmol+/kg), and Cu (12.548 mg/kg). Similar soil properties were lower in NFM than in the other soils. The soil properties on the chosen farms did not differ significantly depending on the sampling zone for each organic fertilizer. Therefore, the result indicates that all evaluated organic fertilizers improved soil health compared to NFM, but BS and HU fertilizers led to relatively better soil health improvements than StC, AM, and SF.

Low health literacy and multiple medications in community-dwelling older adults: a population-based cohort study.

OBJECTIVES: Adequate health literacy is important for patients to manage chronic diseases and medications. We examined the association between health literacy and multiple medications in community-dwelling adults aged 50 years and older in England. DESIGN, SETTINGS AND PARTICIPANTS: We included 6368 community-dwelling people of median age 66 years from the English Longitudinal Study of Ageing. Health literacy was assessed at wave 5 (2010/11) with 4 questions concerning a medication label. Four correct answers were categorised as adequate health literacy, otherwise low. Data on medications were collected at wave 6 (2012/13). To examine the difference in the number of medications between low and adequate health literacy, we used zero-inflated negative binomial regression, estimating odds ratio (OR) for zero medication and incidence rate ratios (IRR) for the number of medications, with 95% CIs. Associations were adjusted for demographic, socioeconomic and health characteristics, smoking and cognitive function. We also stratified the analysis by sex, and age (50-64 and ≥65 years). To be comparable with preceding studies, multinomial regression was fitted using commonly used thresholds of polypharmacy (0 vs 1-4, 5-9, ≥10 medications). RESULTS: Although low health literacy was associated with a lower likelihood of being medication-free (OR=0.64, 95% CI: 0.45 to 0.91), health literacy was not associated with the number of medications among those at risk for medication (IRR=1.01, 95% CI: 0.96 to 1.05), and this finding did not differ among younger and older age groups or women. Among men, low health literacy showed a weak association (IRR=1.06, 95% CI: 0.99 to 1.14). Multinomial regression models showed graded risks of polypharmacy for low health literacy. CONCLUSIONS: Although there was no overall association between health literacy and the number of medications, this study does not support the assertion that low health literacy is associated with a notably higher number of medications in men.

Psychosocial consequences of screening-detected abdominal aortic aneurisms: a cross-sectional study.

OBJECTIVE: In Sweden, an abdominal aortic aneurysm (AAA) screening programme was gradually implemented from 2009 to reduce the incidence of rupture and thereby mortality. AAA screening introduces a variety of unintended, but generally unavoidable, harms, e.g. stress and worry. Such psychosocial consequences have previously only been investigated with generic measures. Therefore, the aim of this study was to describe and compare the psychosocial consequences in men with a screening detected AAA to men with a normal screening result after they participated in the Swedish national AAA-screening programme using a validated psychometric instrument. MATERIAL AND METHODS: This study was a cross-sectional survey. Data were originally collected to validate the COS-AAA and has previously been published in details. The Consequences of Screening in Abdominal Aortic Aneurysm (COS-AAA) questionnaire was sent to 250 men with a screening detected AAA and 500 with a normal screening result who were randomly selected from a Swedish population-based screening register. RESULTS: In total, 158 (63%) men with a screening detected AAA and 275 (55%) men with a normal screening result completed the COS-AAA. We found that men with a screening detected AAA reported negative psychosocial consequences to a greater extent in 10 of 13 COS-AAA Part 1 scales, all statistically significant except three (behaviour, sleep and negative experiences from examination). For COS-AAA Part 2, there was a statistically significant difference between groups in four of five scales. CONCLUSIONS: Men diagnosed with a screening detected AAA, reported more negative psychosocial consequences compared to men with a normal result. Screening for abdominal aorta aneurism (AAA) introduces intended benefits and unintended harms. Adequate measures are necessary to determine the balance between them.Key points:This study applied a condition-specific questionnaire with high content validity and adequate psychometric properties to measure psychosocial consequences in men participating in AAA screening.We found that men with a screening detected AAA reported more negative psychosocial consequences than men with a normal aorta size.The risk of negative psychosocial consequences is important to include in the decision making on whether to participate in screening or not.

Normative video head impulse test data in subjects with and without vascular risk factors.

PURPOSE: There is a paucity of age- and vascular risk factor-stratified video head impulse test (vHIT) vestibulo-ocular reflex (VOR) data in the literature. The aim of this study was to investigate the vHIT VOR properties in healthy subjects of different ages and subjects with vascular risk factors. METHODS: This was a prospective observational single-center study at a tertiary referral university hospital in northern Sweden. Healthy participants and subjects with vascular risk factors were investigated with a floor standing external camera vHIT device. Age-stratified mean VOR gain among healthy adults and between group gain and gain asymmetry differences were calculated. RESULTS: We included eighty-eight healthy adults with a mean (range) age of 50 (22-85) years and n = 48 stroke ward patients with vascular risk factors (but without vestibular disease) with a mean (range) age of 74 (42-92) years. The mean VOR gain of horizontal canals decreased at higher ages in healthy subjects (r = - 0.32, p < 0.01, n = 167 canals). The age-stratified mean (SD) VOR gains were < 30 years: 0.98 (0.07), 30-39 years: 0.97 (0.07), 40-49 years: 0.98 (0.06), 50-59 years: 0.99 (0.06), 60-69 years: 0.93 (0.08), ≥ 70 years: 0.89 (0.15). No consistent differences between healthy subjects and subjects with vascular risk factors were seen except for a trend towards more pronounced gain asymmetries in the latter group. CONCLUSIONS: Age, but not vascular risk factors influence VOR gain. Age-adjusted vHIT-measurements may be useful in acute vertigo stroke risk differentiation.

Digitalization and Physician Learning: Individual Practice, Organizational Context, and Social Norm.

INTRODUCTION: The emerging context of online platforms and digitally engaged patients demands new competencies of health care professionals. Although information and communication technologies (ICTs) can strengthen continuous professional development (CPD) and learning at work, more research is needed on ICT for experiential and collegial learning. METHODS: The study builds on prior qualitative research to identify issues and comprises a quantitative assessment of ICT usage for learning in health care. A survey was administered to Swedish physicians participating in a CPD program as part of specialist medical training. Conclusions focused specifically on learning dimensions are drawn from correlation analyses complemented with multiple regression. RESULTS: The findings show that physicians' actual use of ICT is related to perceived performance, social influence, and organizational context. Social norm was the most important variable for measured general usage, whereas performance expectancy (perceived usefulness of ICT) was important for ICT usage for learning. The degree of individual digitalization affects performance and, in turn, actual use. DISCUSSION: The study highlights the need to incorporate ICT effectively into CPD and clinical work. Besides formal training and support for specific systems, there is a need to understand the usefulness of digitalization integrated into practice. Moving beyond instrumentalist views of technology, the model in this study includes contextualized dimensions of ICT and learning in health care. Findings confirm that medical communities are influencers of use, which suggests that an emphasis on collegial expectations for digital collaboration will enhance practitioner adaptation.

Identification of the dynamics of time-varying phase aberrations from time histories of the point-spread function.

To optimally compensate for time-varying phase aberrations with adaptive optics, a model of the dynamics of the aberrations is required to predict the phase aberration at the next time step. We model the time-varying behavior of a phase aberration, expressed in Zernike modes, by assuming that the temporal dynamics of the Zernike coefficients can be described by a vector-valued autoregressive (VAR) model. We propose an iterative method based on a convex heuristic for a rank-constrained optimization problem, to jointly estimate the parameters of the VAR model and the Zernike coefficients from a time series of measurements of the point-spread function (PSF) of the optical system. By assuming the phase aberration is small, the relation between aberration and PSF measurements can be approximated by a quadratic function. As such, our method is a blind identification method for linear dynamics in a stochastic Wiener system with a quadratic nonlinearity at the output and a phase retrieval method that uses a time-evolution-model constraint and a single image at every time step.

Flipped healthcare for better or worse.

The medical profession is highly specialized, demanding continuous learning, while also undergoing rapid development in the rise of data-driven healthcare. Based on clinical scenarios, this study explores how resident physicians view their roles and practices in relation to informed patients and patient-centric digital technologies. The paper illustrates how the new role of patients alters physicians' work and use of data to learn and update their professional practice. It suggests new possibilities for developing collegial competence and using patient experiences more systematically. Drawing on the notion of flipped healthcare, we argue that there is a need for new professional competencies in everyday data work, along with a change in attitudes, newly defined roles, and better ways to identify and develop reliable online sources. Finally, the role of patients, not only as consumers but also producers of healthcare, is a rather formidable and complex cultural change to be addressed.

High hospital readmission rates for patients aged ≥65 years associated with low socioeconomic status in a Swedish region: a cross-sectional study in primary care.

OBJECTIVE: There is a presumption that hospital readmission rates amongst persons aged ≥65 years are mainly dependent on the quality of care. In this study, our primary aim was to explore the association between 30-day hospital readmission for patients aged ≥65 years and socioeconomic characteristics of the studied population. A secondary aim was to explore the association between self-reported lack of strategies for working with older patients at primary health care centres and early readmission. DESIGN: A cross-sectional ecological study and an online questionnaire sent to the heads of the primary health care centres. We performed correlation and regression analyses. SETTING AND SUBJECTS: Register data of 283,063 patients in 29 primary health care centres in the Region Örebro County (Sweden) in 2014. MAIN OUTCOME MEASURE: Thirty-day hospital readmission rates for patients aged ≥65 years. Covariates were socioeconomic characteristics among patients registered at the primary health care centre and eldercare workload. RESULTS: Early hospital readmission was found to be associated with low socioeconomic status of the studied population: proportion foreign-born (r = 0.74; p < 0.001), proportion unemployed (r = 0.73; p < 0.001), Care Need Index (r = 0.74; p < 0.001), sick leave rate (r = 0.51; p < 0.01) and average income (r = -0.40; p = 0.03). The proportion of unemployed alone could explain up to 71.4% of the variability in hospital readmission (p < 0.001). Primary health care centres reporting lack of strategies to prevent readmissions in older patients did not have higher hospital readmission rates than those reporting they had such strategies. CONCLUSION: Primary health care centres localized in neighbourhoods with low socioeconomic status had higher rates of hospital readmission for patients aged ≥65. Interventions aimed at reducing hospital readmissions for older patients should also consider socioeconomic disparities. Key Points In Sweden, hospital readmission within 30 days among patients aged ≥65 has been used as a measure of quality of primary care for the elderly. However, in our study, elderly 30-day readmission was associated with low neighbourhood socioeconomic status. A simple survey in one Swedish region showed that the primary health care centres that lacked active strategies for working with aged patients did not have higher hospital readmission rates than those that reported having strategies. Interventions aimed at reducing elderly hospital readmissions should therefore also consider the socioeconomic disparities in the elderly.

De novo biosynthesis of anthocyanins in Saccharomyces cerevisiae.

Anthocyanins (ACNs) are plant secondary metabolites responsible for most of the red, purple and blue colors of flowers, fruits and vegetables. They are increasingly used in the food and beverage industry as natural alternative to artificial colorants. Production of these compounds by fermentation of microorganisms would provide an attractive alternative. In this study, Saccharomyces cerevisiae was engineered for de novo production of the three basic anthocyanins, as well as the three main trans-flavan-3-ols. Enzymes from different plant sources were screened and efficient variants found for most steps of the biosynthetic pathway. However, the anthocyanidin synthase was identified as a major obstacle to efficient production. In yeast, this enzyme converts the majority of its natural substrates leucoanthocyanidins into the off-pathway flavonols. Nonetheless, de novo biosynthesis of ACNs was shown for the first time in yeast and for the first time in a single microorganism. It provides a framework for optimizing the activity of anthocyanidin synthase and represents an important step towards sustainable industrial production of these highly relevant molecules in yeast.

The dilemma of repeat weak opioid prescriptions - experiences from swedish GPs.

OBJECTIVE: To explore general practitioners' (GP) experiences of dealing with requests for the renewal of weak opioid prescriptions for chronic non-cancer pain conditions. DESIGN: Qualitative focus group interviews. Systematic text condensation analysis. SETTING AND SUBJECTS: 15 GPs, 4 GP residents and 2 interns at two rural and two urban health centres in central Sweden. MAIN OUTCOME MEASURES: Strategies for handling the dilemma of prescribing weak opioids without seeing the patient. RESULTS: After analysing four focus group interviews we found that requests for prescription renewals for weak opioids provoked adverse feelings in the GP regarding the patient, colleagues or the GP's inner self and were experienced as a dilemma. To deal with this, the GP could use passive as well as active strategies. Active strategies, like discussing the dilemma with colleagues and creating common routines regarding the renewal of weak opioids, may improve prescription habits and support physicians who want to do what is medically correct. CONCLUSION: Many GPs feel umcomfortable when prescribing weak opioids without seeing the patient. This qualitative study has identified strategic approaches to deal with that issue. Key points  Opioid prescription for chronic non-cancer pain is known to cause discomfort, feelings of guilt and conflicts for the prescribing doctor. From focus group interviews with GPs we found that to deal with this: • Doctors can use active strategies, such as confronting the patient or creating common routines together with their colleagues, or… • They can use passive coping strategies such as accepting the situation, handing over the responsibility to the patient or choosing not to see that there is a problem. • Opportunities for doctors to discuss prescription routines may be the best way to influence prescription habits.

Flawed communications: Health professionals' experience of collaboration in the care of frail elderly patients.

AIMS: Frail elderly patients who have multiple illnesses do not fare well in modern health care systems, mainly due to a lack of care planning and flawed communication between health professionals in different care organisations. This is especially noticeable when patients are discharged from hospital. The aim of this study was to explore health care professionals' experience of obstacles and opportunities for collaboration. METHODS: Health professionals were invited to participate in three focus groups, each consisting of a hospital physician, a primary care physician, a hospital nurse, a primary care nurse, a municipal home care nurse or an assistant officer, a physical or occupational therapist and a patient or a family member representative. These individual people were then asked to discuss the obstacles and opportunities for communication between themselves and with the patients and their relatives when presented with the case report of a fictitious patient. Content analysis was used to identify categories. RESULTS: Several obstacles were identified for effective communication and care planning: insufficient communication with patients and relatives; delayed collaboration between care-givers; the lack of an adequate responsible person for care planning; and resources not being distributed according to the actual needs of patients. The absence of an overarching responsibility for the patient, beyond organisational borders, was a recurring theme. These obstacles could also be seen as opportunities. CONCLUSIONS: Obstacles for collaboration were found on three levels: societal, organisational and individual. As health care professionals are well aware of the problems and also see solutions, management for health care should support employees' own initiatives for changes that are of benefit in the care of frail elderly patients with multiple illnesses.

Experiences of the screening process and the diagnosis abdominal aortic aneurysm among 65-year-old men from invitation to a 1-year surveillance.

The prevalence of abdominal aortic aneurysm (AAA) is reported to be 2.2%-8% among men >65 years. During recent years, screening programs have been developed to detect AAA, prevent ruptures, and thereby saving lives. Therefore, most men with the diagnosis are monitored conservatively with regular reviews. The objective of the study was to describe how men diagnosed with abdominal aortic aneurysm <55 mm discovered by screening experience the process and diagnosis from invitation to 1 year after screening. A total of eleven 65-year-old men were included in three focus groups performed in a University Hospital in Sweden. These were qualitatively analyzed using manifest and latent content analysis. The experience of the screening process and having an abdominal aortic aneurysm in a long-term perspective revealed three categories: "trusting the health care system," emphasizing the need for continual follow-ups to ensure feelings of security; "the importance size," meaning that the measure was abstract and hard to understand; and "coping with the knowledge of abdominal aortic aneurysm," denoting how everyday life was based mostly on beliefs, since a majority lacked understanding about the meaning of the condition. The men want regular surveillance and surrendered to the health care system, but simultaneously experienced a lack of support thereof. Knowing the size of the aorta was important. The men expressed insecurity about how lifestyle might influence the abdominal aortic aneurysm and what they could do to improve their health condition. This highlights the importance of communicating knowledge about the abdominal aortic aneurysm to promote men's feelings of security and giving space to discuss the size of the aneurysm and lifestyle changes.

Consequences of screening in abdominal aortic aneurysm: development and dimensionality of a questionnaire.

BACKGROUND: In interview studies, men under surveillance for screening-detected abdominal aortic aneurysms have reported ambivalence towards this diagnosis: the knowledge was welcomed together with worries, feelings of anxiety and existential thoughts about life's fragility and mortality due to the diagnosis. Previous surveys about health-related quality of life aspects among men under surveillance for screening-detected aneurysm have all used generic patient-reported outcomes. Therefore, the aim of this study was to extend the core-questionnaire Consequences of Screening for use in abdominal aortic aneurysm screening by testing for comprehension, content coverage, dimensionality, and reliability. METHODS: In interviews, the suitability, content coverage, and relevance of the core-questionnaire Consequences of Screening were tested on men under surveillance for a screeningdetected abdominal aortic aneurysm. The results were thematically analysed to identify the key consequences of abnormal screening results. Item Response Theory and Classical Test Theory were used to analyse data. Dimensionality, differential item functioning, local response dependency and reliability were established by item analysis, examining the fit between item responses and Rasch models. RESULTS: The core-questionnaire Consequences of Screening was found to be relevant for men offered regular follow-up of an asymptomatic screening-detected abdominal aortic aneurysm.Fourteen themes especially relevant for men diagnosed with a screening-detected abdominal aortic aneurysm were extracted from the interviews: 'Uncertainty about the result of the ultra sound examination', 'Change in body perception', 'Guilt', 'Fear and powerlessness', 'Negative experiences from the examination', 'Emotional reactions', 'Change in lifestyle', 'Better not knowing', 'Fear of rupture', 'Sexuality', 'Information', 'Stigmatised', 'Self-blame for smoking', 'Still regretful smoking'. Altogether, 55 new items were generated: 3 were single items and 13 were only relevant for former or current smokers. 51 of the 52 items belonging to a theme were confirmed to fit Rasch models measuring fourteen different constructs. No differential item functioning and only minor local dependency was revealed between some of the 51 items. CONCLUSIONS: The reliability and the dimensionality of a condition-specific measure with high content validity for men under surveillance for a screening-detected abdominal aortic aneurysm have been demonstrated. This new questionnaire called COS-AAA covers in two parts the psychosocial experience in abdominal aortic aneurysm screening.

Performance and interpretation of spirometry among Swedish hospitals.

BACKGROUND AND AIMS: It is unclear to what extent spirometric performance and interpretation is standardized in Sweden. The aim of this study was to find out how spirometry is performed and interpreted in large Swedish hospitals. METHODS: In telephone interviews, technicians and physicians working with lung function measurements at 21 large Swedish hospitals were interviewed about routines for spirometry. RESULTS: Answers were obtained from 37 of the 42 departments contacted revealing differences in the spirometric routines. Some departments lack a written method description, and three different prediction equations were used among the departments. Different ways of calculating the forced expiratory volume in 1 s (FEV1)/vital capacity (VC) ratio (FEV%) were found and also differences in performance and interpretation of the reversibility test. When diagnosing chronic obstructive pulmonary disease, none of the departments reported using an individualized diagnostic limit of FEV1/VC based on age, sex and height. CONCLUSION: There is a need for standardization of performance and interpretation of the spirometry test in Sweden and probably also in other countries.
