- In recent years, patient-reported outcomes (PROs) have received increasing prominence in cardiovascular research and clinical care. An understanding of the variability and global experience of PROs in adults with congenital heart disease (CHD), however, is still lacking. Moreover, information on epidemiological characteristics and the frailty phenotype of older adults with CHD is minimal. The APPROACH-IS II study was established to address these knowledge gaps. This paper presents the design and methodology of APPROACH-IS II.APPROACH-IS II is a cross-sectional global multicentric study that includes Part 1 (assessing PROs) and Part 2 (investigating the frailty phenotype of older adults). With 53 participating centers, located in 32 countries across six continents, the aim is to enroll 8000 patients with CHD. In Part 1, self-report surveys are used to collect data on PROs (e.g., quality of life, perceived health, depressive symptoms, autonomy support), and explanatory variables (e.g., social support, stigma, illness identity, empowerment). In Part 2, the cognitive functioning and frailty phenotype of older adults are measured using validated assessments.APPROACH-IS II will generate a rich dataset representing the international experience of individuals in adult CHD care. The results of this project will provide a global view of PROs and the frailty phenotype of adults with CHD and will thereby address important knowledge gaps. Undoubtedly, the project will contribute to the overarching aim of improving optimal living and care provision for adults with CHD.

Tidskriftsartikel (refereegranskat)abstract
- Objective: We aimed to delineate a novel soluble Biglycan Neo-epitope-BGN262 in saliva from young reference and osteoarthritic horses in conjunction with the influence of short-term training exercise, riding surface hardness, circadian rhythm, and feeding on its soluble levels. Design: A custom-made inhibition ELISA was used for the quantification of BGN262 in saliva. Cohort 1: A cross-sectional study comprising reference (N = 19) and OA horses (N = 9) with radiographically classified subchondral bone sclerosis. Receiver operating characteristic curve analysis was performed to evaluate the robustness of BGN262. Cohorts 2 (N = 5) & 3 (N = 7): Longitudinal studies of sampling during a short-term training exercise (sand-fibre) and a cross-over design of short-training exercise on 2 different riding arenas (sand and sand-fibre), respectively. Capillary western immunoassay was used to determine the BGN262 molecular size in a selection of saliva samples collected from cohort 1. Results: Cohort 1: Salivary BGN262 levels were significantly higher in the OA group. The Receiver operating characteristic curve analysis showed an area under the curve of 0.8304 [0.6386 to 1.022], indicating a good separation from the reference group. Cohorts 2 & 3: Salivary BGN262 levels significantly changed during the exercise on sand and sand-fibre arena, with a trend towards higher levels for sand-fibre. The size of the BGN262 fragment determined by Capillary western assay was 18 kDa. Conclusions: The data presented show saliva BGN262 levels as a novel biomarker in evaluating the influence of exercise, and interaction with riding arenas alongside assessing osteoarthritis severity.

Aesthetic Values in Home and Consumer Studies : Investigating the Secret Ingredient in Food Education
- 2023
-
Ingår i: Frontiers in Education. - : Frontiers Media S.A.. - 2504-284X. ; 8
-
Tidskriftsartikel (refereegranskat)abstract
- Food is a part of everyday life, and formal food education is included in compulsory education in many countries, for example through the subject Home and Consumer Studies (HCS). While food education is often underpinned by public health concerns such as preventing non-communicable diseases and promoting cooking skills, there has been little focus on aesthetic aspects of teaching and learning about food. This study therefore aims to gain understanding of aesthetic values as a part of HCS food educational practices. Aesthetic values are here regarded as socially and culturally shared, and related to notions of pleasure and taste. As this study uses a pragmatist approach, aesthetic values are seen as constituted in encounters, encompassing experiencing individual(s), artifacts, and context. By thematically analyzing empirical data from an exploratory case study, including classroom observations, student focus groups, and teacher interviews, we show how values are constituted as culinary, production, and bodily aesthetics. Culinary aesthetics involved cooking processes, cooking skills, and presentation of food and meals. Production aesthetics involved foods’ origin and degree of pre-processing, whereas bodily aesthetics related to bodily consequences of eating. Aesthetic values were vital features of the educational practices studied and played a key role in bringing the practices forward. They also indicated what counted as valid, or desired, outcomes and thereby steered events in certain directions. The study highlights the significance of aesthetic values and argues in favor of acknowledging aesthetics in planning, undertaking, and evaluating HCS food education.

Beyond the plate : Food and health, aesthetics and meaning-making in Home and consumer studies
- 2024
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The overall aim of this thesis is to cultivate understandings of how meanings regarding food and health are made within the school subject home and consumer studies (HCS). The thesis builds on empirical data generated through a comprehensive case study, where 12 students from one school class and their two teachers were followed in HCS over the course of a school year. The methods used were observations, interviews, focus groups, and document collection. This work comprises four papers, where Paper I covers students’ meaning-making during cooking with a focus on aesthetic judgments. The results of Paper I illustrate different ways in which the students used aesthetic judgments, and how aesthetics became integral to meaning-making. Paper II investigates food for health as educational content, using qualification, socialization, and subjectification as an analytical framework. The results exemplify how these three educational functions can be operationalized empirically, and how a given educational content opens up for meaning-making that goes beyond learning facts and skills. In Paper III, thematic analysis is used to gain an overview of which aesthetic values were constituted in the studied practices, and how. Thus, the central roles of aesthetics in HCS food education were further illustrated. Lastly, Paper IV investigates use of the plate model as a food educational tool, using three planes of analysis as a framework. The results demonstrate how the plate model can be useful in food and health education, but also that it needs to be used with caution, for example to avoid conveying a rigid message of “right” and “wrong” dishes. Taken together, the results of the four papers show how food was a central transactant in the studied practices, i.e., how the food itself became an important co-actor in the meaning-making processes. Second, the discrepancy between the students’ focus on immediate food experiences and the teachers’ instrumental orientation is highlighted. In summary, this thesis provides empirically grounded contributions to support food educational practices in general, and HCS subject didactics in particular. Additionally, it strengthens the position of HCS as a subject to be reckoned with in wider didactic contexts, as well as in the emerging field of disciplinary aesthetics.

Useful but overused? The “plate model” as a food educational tool in home economics
- 2024

Tidskriftsartikel (refereegranskat)abstract
- The plate model is widely used to promote healthy eating. Despite extensive adoption in dietary guidelines, the model’s role in food educational practices is scarcely studied. The present study aimed to explore the plate model as a food educational tool in the school subject Home Economics (HE). Use of the plate model was investi-gated with Rogoff’s three planes of analysis as a framework. The research question was: “How is the plate model used in a food educational practice, considering institutional, interpersonal, and personal planes?” Data from video-recorded classroom observa-tions, focus groups, interviews, and text documents were analyzed. The data were generated through a case study, with twelve stu-dents and two HE-teachers followed over the course of a school year. Results show how the plate model was framed as the right way of eating. Nutritionally “proper” food was described, with the model functioning as a bridge linking (abstract) nutritional content with (concrete) dishes. This way of using the model might hamper understandings of fundamental principles for nutritional classifica-tion. Moreover, those who do not eat plate model-type dishes may be wrongly judged. Supported by empirical events, this study shows how the plate model can be useful – but also overused – in food education.

Tidskriftsartikel (refereegranskat)abstract
- This study aims to contribute to the understanding of food for health as educational content in Home and Consumer Studies (HCS), specifically targeting three educational functions: (i) qualification, (ii) socialization, and (iii) subjectification. Data came from a comprehensive case study, where one school class and two HCS teachers were followed during one school year. Fourteen classroom observations and eight teacher interviews were included. It is shown how qualification functions comprise nutrition knowledge and cooking skills, how socialization functions entail, e.g., dichotomous values of food as “good” or “bad,” and how conscious consumers who take personal responsibility for themselves and the environment become promoted subjects. Taken together, the results illustrate how educational content can have consequences beyond those intended. Based on the results, an argument is made about the relevance for HCS teachers to critically reflect on their teaching and its potential educational consequences.

Metodutveckling för blodprovstagning på filterpapper
- 2022
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Blodprov för metallanalyser tas vanligtvis via prov av venblod från armvecket. Detta är dock eninvasiv metod och provtagningen måste utföras av medicinskt utbildad personal. Ett sätt att erhållablod med en mindre invasiv metod och som ger betydligt mindre blodvolym är att genom ett stick ifingret droppa kapillärblod på ett filterpapper som får torka. Ytterligare fördelar med dennaprovtagningsmetod är att det blir möjligt med ”självprovtagning” och att för en mindre kostnad kanblod samlas in från fler personer.Vi genomförde ett utvecklingsprojekt för att ta fram en metod för att samla in och mäta metallernakadmium, kvicksilver och bly i torkat blod (blodspottar på filterpapper) erhållet via självprovtagninggenom stick i fingret.Vi tog fram en sur tvättmetod för att tvätta bort metaller (bakgrundshalter) i filterpapper innan dekan användas för provtagning. Vi utvecklade en enkel men effektiv alkalisk urlakningsmetod avmetaller i blodspottarna. Vi tog fram ett självprovtagningskit för blodspottar samt instruktionsvideodesignat för att minimera kontaminering av metaller i omgivningsmiljön. Vi jämfördevenblodsprovtagning med självprovstagning för 17 försökspersoner och fann överensstämmelseframförallt för bly. Vi gjorde en inter-laboratoriejämförelse för mätning av metaller i blodspottar frånfem personer och fann överensstämmelse för kvicksilver och bly.Studien visar att det är möjligt att mäta toxiska metaller i små volymer från blodspottar erhållna viasjälvprovtagning. Emellertid skilde sig halterna i venblod och i blodspottar för vissa personer ochframförallt för kadmium. Det beror troligen på att blodspottarna kan kontamineras vid utstansningmed de stansverktyg som finns att köpa på marknaden. Ytterligare metodutveckling via framtagningav adekvat stansverktyg rekommenderas för att kunna mäta kadmium i blodspottar samt att däreftertesta metoden i HÄMI-projekt.

Developing the preterm breastfeeding attitudes instrument : A tool for describing attitudes to breastfeeding among health care professionals in neonatal intensive care
- 2021
-
Ingår i: Midwifery. - : Elsevier BV. - 0266-6138 .- 1532-3099. ; 94
-
Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE: The aim of this study was to develop an instrument that measures health care professionals' (HCPs) attitudes to breastfeeding and skin-to-skin contact in relation to the Baby-Friendly Hospital Initiative for neonatal intensive care.DESIGN: The study was part of a larger project aiming to revive the Ten Steps to Successful Breastfeeding for both full-term and preterm infants. The study had a pre-test/post-test design using online questionnaires distributed by email before and after a training programme.SETTING AND PARTICIPANTS: A total of 70 specialist registered nurses, registered nurses, assistant nurses and physicians working at a Swedish neonatal intensive care unit answered 55 breastfeeding attitudes questions online before the training. The Preterm Breastfeeding Attitudes Instrument (PreBAI) consists of twelve of these 55 items/questions, selected using exploratory factor analysis.MEASUREMENTS AND FINDINGS: Higher scores indicated more positive attitudes and the median total PreBAI score was 42 points (out of 48), on both the pre- and the post-test questionnaires, showing no significant difference. In the pre-test questionnaire, the majority of HCPs (84%) stated that they needed further breastfeeding training. They also stated that they perceived breastfeeding as very important, scoring a median of 10 (range 5-10) points on a 10-point scale. Three separate underlying dimensions were identified in the questionnaire, indicating different attitudes: Facilitating (five items), Regulating (four items), and Breastfeeding- and skin-to-skin contact-friendly (three items). A positive correlation was found between how many years the HCPs had worked in neonatal care, and their PreBAI score (rs = 0.383, p = 0.001). Those who had previously received extra breastfeeding education scored higher on the instrument.KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: Neonatal intensive care units need to increase their efforts to support breastfeeding. An important factor for mothers when establishing breastfeeding is support from well-trained professionals with a positive attitude to breastfeeding. The PreBAI could be a useful tool for identifying attitudes among HCPs before and after attending a breastfeeding training programme.

- Support from health care professionals (HCPs) with good knowledge and positive attitudes toward breastfeeding has been associated with better breastfeeding outcomes in the mothers of preterm infants. The aim of the study was to describe HCPs' experiences of a breastfeeding training program. A total of 48 specialist registered nurses, registered nurses, assistant nurses and physicians working at a neonatal intensive care unit attended a breastfeeding training program and answered a questionnaire including Likert scales and open-ended questions. The participants reported that their interest in breastfeeding had increased as a median (range) of 10 (8–10) on a 10-point scale and rated to what extent they had received new tools for breastfeeding support as a median of 10 (8–10) after training. There were no differences in the median between different professions' ratings. Qualitative content analysis of the open-ended questions resulted in two categories: Discussions of the case scenarios in the group and Knowledge regarding breastfeeding. The results showed that discussions based on breastfeeding scenarios were perceived as valuable; the health care professionals reported receiving new knowledge and useful practical skills. This program was shown to increase health care professionals’ interest in breastfeeding and is useful for different health care professions.

Mothers' Adaptation to a Late Preterm Infant When Breastfeeding
- 2020

Tidskriftsartikel (refereegranskat)abstract
- The aim of this study was to psychometrically test the Adaptation to the Late Preterm Infant when Breastfeeding Scale (ALPIBS) and also to test how a mother's self-efficacy predicts adaptation to a late preterm infant when breastfeeding. This study had a longitudinal and prospective design, and data collection was consecutive. Mothers (n = 105) with infants born between and weeks were recruited from a neonatal intensive care unit or a maternity unit. The ALPIBS was developed using exploratory factor analysis, and the association between breastfeeding self-efficacy and ALPIBS score was examined using linear regression analysis. The Breastfeeding Self-Efficacy Scale-Short Form instrument was used to measure self-efficacy in breastfeeding. A higher degree of self-efficacy was significantly associated with a higher degree of adaptation to the late preterm infant's breastfeeding behavior (P < .001). We identified 4 separate underlying factors measured by 11 items in the ALPIBS: (A) breastfeeding is a stressful event; (B) the infant should breastfeed as often as he or she wants; (C) a mother has to breastfeed to be a good mother; and (D) it is important to ensure control over the infant's feeding behavior. There is a link between self-efficacy and ALPIBS score, and self-efficacy is a modifiable factor that influences breastfeeding.

Tidskriftsartikel (refereegranskat)abstract
- Background: Diesel engine exhaust causes adverse health effects. Meanwhile, the impact of renewable diesel exhaust, such as hydrotreated vegetable oil (HVO), on human health is less known. Nineteen healthy volunteers were exposed to HVO exhaust for 3 h in a chamber with a double-blind, randomized setup. Exposure scenarios comprised of HVO exhaust from two modern non-road vehicles with 1) no aftertreatment system ('HVOPM+NOx' PM1: 93 mu g-m(-3), EC: 54 mu g-m(-3), NO: 3.4 ppm, -NO2: 0.6 ppm), 2) an aftertreatment system containing a diesel oxidation catalyst and a diesel particulate filter ('HVONOx' PM1: similar to 1 mu g-m(-3), NO: 2.0 ppm, -NO2: 0.7 ppm) and 3) filtered air (FA) as control. The exposure concentrations were in line with current EU occupational exposure limits (OELs) of NO, -NO2, formaldehyde, polycyclic aromatic hydrocarbons (PAHs), and the future OEL (2023) of elemental carbon (EC). The effect on nasal patency, pulmonary function, and self-rated symptoms were assessed. Calculated predicted lung deposition of HVO exhaust particles was compared to data from an earlier diesel exhaust study. Results: The average total respiratory tract deposition of PM1 during -HVO(PM+ NO)x was 27 mu g-h(-1). The estimated deposition fraction of HVO PM1 was 40-50% higher compared to diesel exhaust PM1 from an older vehicle (earlier study), due to smaller particle sizes of the -HVOPM+ NOx exhaust. Compared to FA, exposure to -HVOPM+ NOx and -HVONOx caused higher incidence of self-reported symptoms (78%, 63%, respectively, vs. 28% for FA, p < 0.03). Especially, exposure to -HVOPM+ NOx showed 40-50% higher eye and throat irritation symptoms. Compared to FA, a decrement in nasal patency was found for the -HVONOx exposures (- 18.1, 95% CI: - 27.3 to - 8.8 L-min(-1), p < 0.001), and for the -HVOPM+ NOx (- 7.4 (- 15.6 to 0.8) L -min(-1), p = 0.08). Overall, no clinically significant change was indicated in the pulmonary function tests (spirometry, peak expiratory flow, forced oscillation technique). Conclusion: Short-term exposure to HVO exhaust concentrations corresponding to EU OELs for one workday did not cause adverse pulmonary function changes in healthy subjects. However, an increase in self-rated mild irritation symptoms, and mild decrease in nasal patency after both HVO exposures, may indicate irritative effects from exposure to HVO exhaust from modern non-road vehicles, with and without aftertreatment systems.

Highly elevated systemic inflammation is a strong independent predictor of early mortality in advanced non-small cell lung cancer

Tidskriftsartikel (refereegranskat)abstract
- BackgroundAmple evidence support inflammation as a marker of outcome in non-small cell lung cancer (NSCLC). Here we explore the outcome for a subgroup of patients with advanced disease and substantially elevated systemic inflammatory activity.MethodsThe source cohort included consecutive patients diagnosed with NSCLC between January 2016 – May 2017 (n = 155). Patients with active infection were excluded. Blood parameters were examined individually, and cut-offs (ESR > 60 mm, CRP > 20 mg/L, WBC > 10 × 109, PLT > 400 × 109) were set to define the group of hyperinflamed patients. A score was developed by assigning one point for each parameter above cut-off (0–4 points).ResultsHigh systemic inflammation was associated with advanced stage and was seldom present in limited NSCLC. However, the one year survival of patients in stage IIIB-IV (n = 93) with an inflammation score of ≥2 was 0% compared to 33% and 50% among patients with a score of 1 and 0 respectively. The effect of a high inflammation score on overall survival remained significant in multi-variate analysis adjusted for confounding factors. The independent hazard ratio of an inflammation score ≥ 2 in multi-variate analysis (HR 3.43, CI 1.76–6.71) was comparable to a change in ECOG PS from 0 to 2 (HR 2.42, CI 1.13–5.18).ConclusionOur results show that high level systemic inflammation is a strong independent predictor of poor survival in advanced stage NSCLC. This observation may indicate a need to use hyperinflammation as an additional clinical parameter for stratification of patients in clinical studies and warrants further research on underlying mechanisms linked to tumor progression.

- Nerve growth factor (NGF) is a neurotrophin with many functions. In humans, it is involved in inflammation, nerve growth, apoptosis and pain signalling. Increased concentrations of NGF in synovial fluid has been shown in humans and dogs with osteoarthritis. Despite osteoarthritis being a common problem in horses, no studies have previously been published on NGF in the equine joint. The aim of this study was to quantify NGF in equine synovial fluid from healthy joints, acutely inflamed septic joints and joints with structural changes associated with osteoarthritis. A secondary aim was to identify the localisation of NGF and its two receptors, TrkA and p75(NTR) in healthy and osteoarthritic articular cartilage. NGF concentrations in synovial fluid from osteoarthritic joints (n = 27), septic joints (n = 9) and healthy joints (n = 16) were determined by ELISA. In addition, articular cartilage from osteoarthritic and healthy joints was examined for NGF, TrkA and P75(NTR) using immunohistochemistry staining. NGF was present in equine synovial fluid and articular cartilage. Compared to synovial fluid from healthy joints, NGF concentration was higher in synovial fluid from joints with structural osteoarthritic changes (P = 0.032) or acute septic inflammation (P = 0.006). In articular cartilage with severe osteoarthritic changes, there was more abundant positive immunohistochemistry staining for NGF and its receptors than in normal articular cartilage. Further studies should focus on identifying precursor forms of NGF, and on receptor expression and downstream signalling of TrkA and P75(NTR) in health and disease. (C) 2020 The Author(s).

- Development of T cell-directed immune checkpoint inhibitors (ICI) has revolutionized metastatic melanoma (MM) therapy, but <50% of treated patients experience durable responses. This phase I trial (NCT01946373) investigates the safety/feasibility of tumor-infiltrating lymphocyte (TIL) adoptive cell therapy (ACT) combined with dendritic cell (DC) vaccination in MM patients progressing on ICI. An initial cohort (5 patients) received TIL therapy alone to evaluate safety and allow for optimization of TIL expansion protocols. A second cohort (first-in-man, 5 patients) received TIL combined with autologous tumor lysate-loaded DC vaccination. All patients received cyclophosphamide/fludarabine preconditioning prior to, and intravenous (i.v.) IL-2 after, TIL transfer. The DC vaccine was given as five intradermal injections after TIL and IL-2 administration. [F-18]-FDG PET/CT radiology was performed to evaluate clinical response, according to RECIST 1.1 (on the CT part). Immunological monitoring was performed by flow cytometry and T-cell receptor (TCR) sequencing. In the safety/optimization cohort, all patients had a mixed response or stable disease, but none durable. In the combination cohort, two patients experienced complete responses (CR) that are still ongoing (>36 and >18 months, respectively). In addition, two patients had partial responses (PR), one still ongoing (>42 months) with only a small bone-lesion remaining, and one of short duration (<4 months). One patient died early during treatment and did not receive DC. Long-lasting persistency of the injected TILs was demonstrated in blood. In summary, we report clinical responses by TIL therapy combined with DC vaccination in 4 out of 4 treated MM patients who previously failed ICI.

Enhancing monitoring and transboundary collaboration for conserving migratory species under global change : The priority case of the red kite
- 2022

Forskningsöversikt (refereegranskat)abstract
- Calls for urgent action to conserve biodiversity under global change are increasing, and conservation of migratory species in this context poses special challenges. In the last two decades the Convention on the Conservation of Migratory Species of Wild Animals (CMS) has provided a framework for several subsidiary instruments including action plans for migratory bird species, but the effectiveness and transferability of these plans remain unclear. Such laws and policies have been credited with positive outcomes for the conservation of migratory species, but the lack of international coordination and on-ground implementation pose major challenges. While research on migratory populations has received growing attention, considerably less emphasis has been given to integrating ecological information throughout the annual cycle for examining strategies to conserve migratory species at multiple scales in the face of global change. We fill this gap through a case study examining the ecological status and conservation of a migratory raptor and facultative scavenger, the red kite (Milvus milvus), whose current breeding range is limited to Europe and is associated with agricultural landscapes and restricted to the temperate zone. Based on our review, conservation actions have been successful at recovering red kite populations within certain regions. Populations however remain depleted along the southern-most edge of the geographic range where many migratory red kites from northern strongholds overwinter. This led us to a forward-looking and integrated strategy that emphasizes international coordination involving researchers and conservation practitioners to enhance the science-policy-action interface. We identify and explore key issues for conserving the red kite under global change, including enhancing conservation actions within and outside protected areas, recovering depleted populations, accounting for climate change, and transboundary coordination in adaptive conservation and management actions. The integrated conservation strategy is sufficiently general such that it can be adapted to inform conservation of other highly mobile species subject to global change.

Accelerating target deconvolution for therapeutic antibody candidates using highly parallelized genome editing

Tidskriftsartikel (refereegranskat)abstract
- Therapeutic antibodies are transforming the treatment of cancer and autoimmune diseases. Today, a key challenge is finding antibodies against new targets. Phenotypic discovery promises to achieve this by enabling discovery of antibodies with therapeutic potential without specifying the molecular target a priori. Yet, deconvoluting the targets of phenotypically discovered antibodies remains a bottleneck; efficient deconvolution methods are needed for phenotypic discovery to reach its full potential. Here, we report a comprehensive investigation of a target deconvolution approach based on pooled CRISPR/Cas9. Applying this approach within three real-world phenotypic discovery programs, we rapidly deconvolute the targets of 38 of 39 test antibodies (97%), a success rate far higher than with existing approaches. Moreover, the approach scales well, requires much less work, and robustly identifies antibodies against the major histocompatibility complex. Our data establish CRISPR/Cas9 as a highly efficient target deconvolution approach, with immediate implications for the development of antibody-based drugs.

- OBJECTIVE: To study childbirth and the risk of miscarriage and infertility among women who have received a diagnosis of type 2 diabetes before the start of their reproductive journey.DESIGN: Register-based cohort study using the Skåne Healthcare Register SETTING: All healthcare visits for the whole population of the southernmost region in Sweden over the past 20 years PATIENT(S): All women who were aged 18-45 years between January 1, 1998 and December 31, 2019 and who received a clinical diagnosis of type 2 diabetes before their first childbirth, miscarriage, or infertility diagnosis (n = 230) were compared with a healthcare-seeking population of women without any type of diabetes, matched for calendar year and age (n = 179,434).INTERVENTION(S): None MAIN OUTCOME MEASURE(S): Childbirth, miscarriage, and infertility diagnosis RESULT(S): The birthrate was lower among women with type 2 diabetes (62.6% vs. 83.8%), and they were less likely to give birth (crude risk ratio [RR] = 0.73, 95% confidence interval [CI]: 0.66-0.81). They had a higher risk of experiencing a miscarriage (RR = 1.88, 95% CI: 1.50-2.36). The risk of infertility was increased (RR = 3.44, 95% CI: 2.88-4.10) as was the risk of having infertility and not giving birth (RR = 4.47, 95% CI: 3.44-5.82). All results remained the same after adjustment for polycystic ovary syndrome and obesity.CONCLUSION(S): Women with type 2 diabetes with onset before their reproductive journey were more often childless compared with women without diabetes and had a higher risk of experiencing both miscarriage and infertility. This patient group may be in need of targeted information regarding potential fertility issues as part of their clinical treatment.

- Functionally uniform monocultures have remained the paradigm in microalgal cultivation despite the apparent challenges to avoid invasions by other microorganisms. A mixed microbial consortium approach has the potential to optimize and maintain biomass production despite of seasonal changes and to be more resilient toward contaminations. Here we present a 3-year outdoor production of mixed consortia of locally adapted microalgae and bacteria in cold temperate latitude. Microalgal consortia were cultivated in flat panel photobioreactors using brackish Baltic Sea water and CO2 from a cement factory (Degerhamn, Cementa AB, Heidelberg Cement Group) as a sustainable CO2 source. To evaluate the ability of the microbial consortia to maintain stable biomass production while exposed to seasonal changes in both light and temperature, we tracked changes in the microbial community using molecular methods (16S and 18S rDNA amplicon sequencing) and monitored the biomass production and quality (lipid, protein, and carbohydrate content) over 3 years. Despite changes in environmental conditions, the mixed consortia maintained stable biomass production by alternating between two different predominant green microalgae (Monoraphidium and Mychonastes) with complementary tolerance to temperature. The bacterial population was few taxa co-occured over time and the composition did not have any connection to the shifts in microalgal taxa. We propose that a locally adapted and mixed microalgal consortia, with complementary traits, can be useful for optimizing yield of commercial scale microalgal cultivation.

- Background: During the COVID-19 pandemic, intensive care units (ICUs) were under heavy pressure, with a significantly increased number of severely ill patients. Hospitals introduced restrictions, and families could not visit their ill and dying family members. Patients were cared for without privacy, and several died in shared patient rooms, leaving the intensive care nurse to protect the patient's need for loving care in a vulnerable situation at the end of life.Aims: This study aimed to investigate how piloting and watch over were revealed in end-of-life care for patients with COVID-19 in intensive care COVID-19.Study Design: A qualitative study was conducted with an abductive approach was conducted. Data were collected via semi-structured interviews to cover the research area while allowing the informant to talk freely about the topic; 11 informants were interviewed.Results: The findings are presented based on four categories: The road to the decision, End-of-life care, Farewell of close family members and Closure. Each category and subcategory reveal how piloting and watch over were addressed in the end-of-life care of patients with COVID-19 in the ICU during the pandemic. Overall findings indicated that workload and organization of care directly affect the quality of care given, the acceptance of privacy and the possibility of dignified end-of-life care.Conclusions: Workload directly affects the quality of care, risking dehumanization of the patient. Visiting restrictions hindered supporting family members through the various piloting phases. Visiting restrictions also forced the ICU nurses to take on the role of the relative in watching over the patient.Relevance to Clinical Practice: Collaboration with family members is essential for the intensive care nurse to be able to provide a person-centred and dignified end-of-life care.

- OBJECTIVE: COMP (cartilage oligomeric matrix protein) is abundantly expressed in the cardiovascular system, cartilage, and atherosclerotic plaques. We investigated if the total COMP (COMPtotal) and COMP neoepitope (COMPneo) with other cardiovascular markers and clinical parameters could identify symptomatic carotid stenosis. Approach and Results: Blood samples were collected from patients with symptomatic carotid stenosis (stenosis, n=50), patients with stroke without carotid stenosis but small plaques (plaque, n=50), and control subjects (n=50). COMPtotal and COMPneo were measured using an ELISA. Ninety-two cardiovascular disease markers were measured by the Olink CVD kit. The presence of native COMP and COMPneo was determined by immunohistochemistry. The concentration of COMPneo was higher and COMPtotal was lower in the stenosis group. When the concentration was compared between the stenosis and control groups, IL-1ra (interleukin-1 receptor antagonist protein), IL6 (interleukin-6), REN (Renin), MMP1 (matrix metalloproteinase-1), TRAIL-R2 (tumor necrosis factor-related apoptosis-inducing ligand receptor 2), ITGB1BP2 (integrin beta 1 binding protein 2), and COMPneo were predictive of stenosis. Conversely, KLK6 (kallikrein-6), COMPtotal, NEMO (nuclear factor-kappa-B essential modulator), SRC (Proto-oncogene tyrosine-protein kinase Src), SIRT2 (SIR2-like protein), CD40 (cluster of differentiation 40), TF (tissue factor), MP (myoglobin), and RAGE (receptor for advanced glycation end-products) were predictive of the control group. Model reproducibility was good with the receiver operating characteristic plot area under the curve being 0.86. When comparing the plaque group and stenosis group, COMPneo, GAL (galanin), and PTX3 (pentraxin-related protein PTX3) were predictive of stenosis. Model reproducibility was excellent (receiver operating characteristic plot area under the curve 0.92). COMPneo was detected in smooth muscle-, endothelial-, and foam-cells in carotid stenosis. CONCLUSIONS: Degradation of COMP may be associated with atherosclerosis progression and generation of a specific COMP fragment-COMPneo. This may represent a novel biomarker that together with COMPtotal and other risk-markers could be used to identify symptomatic carotid stenosis.

- Purpose: The aim of this paper was to describe how people living with a neurological disability such as multiple sclerosis, Parkinson’s disease and stroke reason regarding using apps to facilitate self-management in everyday life.Material and methods: A qualitative research approach with a focus group methodology was used. The sample comprised 16 participants, 11 men and 5 women, with an average age of 64 years (ranging from 51–80 years). Six participants were diagnosed with multiple sclerosis, six with Parkinson’s disease and four with stroke. Data were analyzed using thematic analysis, which is a method for identifying, analyzing and reporting patterns.Results: The results formed two themes. The first theme “using apps to have control of my health” comprises two subthemes; “monitor and take responsibility for a healthy lifestyle” and “compensate to facilitate everyday life”. The second theme “using the app as a tool and means for communication” also comprised two subthemes; “dare to trust the app” and “feeling safe when sharing information with health care professionals”.Conclusions: The use of apps put increased responsibility on the person and had the possibility to make them more involved in their own care. The use of an app can facilitate a healthy lifestyle and help to monitor disease-specific symptoms. In order to be able to use apps for communication with the health care sector legislation and safety issues need to be considered.
