To read what not is written. Report from a learning study with inferences as a learning object in an upper secondary school.
- 2013

Ingår i: Programme book for WALS-conference, 6-9 September, Gothenburg, Sweden.

Konferensbidrag (refereegranskat)abstract
- An important component in reading comprehension is the ability to make inferences, what sometimes also is described as reading between the lines. The ability can be said to be three-folded, as inferences can be made from an individuals' experiences and thoughts, from the text itself and from other texts. On an upper-secondary school a group of teachers (n= 16) teaching in Swedish found through screening that their students (16 years old) were comfortable with making inferences using their own experiences and thoughts, but less skilled in making inferences by using clues in the text. The teachers chose as a learning-object the ability to localize clues in the given information and make inferences in the text to be able to read between lines. The aim was to develop the students awareness of that everything in a text not is explicitly written out and to discern values in words. Students should by finding the clues and reading between and outside the lines be able to perceive the main message in the text clearer. The group of teachers conducted a learning study-cycle with three lessons using contrast as the main pattern of variation. Each lesson was jointly planned and then performed for a new group. This presentation is a report from the learning study.

Endophthalmitis after small-gauge vitrectomy : a retrospective case series from Sweden
- 2016
-
Ingår i: Acta Ophthalmologica. - : Wiley-Blackwell. - 1755-375X .- 1755-3768. ; 94:8, s. 829-835

Tidskriftsartikel (refereegranskat)abstract
- Purpose: To investigate the anatomical and functional outcomes of acute-onset endophthalmitis after small-gauge vitrectomy. Methods: Retrospective case series of patients who underwent 23- or 25-gauge vitrectomy at four centres in Sweden between 2008 and 2012. Postvitrectomy endophthalmitis was identified through the search of the journal records of each institution, and the diagnosis was based on clinical criteria regardless of culture results. Results: Twenty-four patients (24 eyes) were included. The incidence of endophthalmitis following small-gauge vitrectomy was 0.14%. Indications for small-gauge vitrectomy enclosed epiretinal membrane (n=13), retinal detachment (n=5) and others (n=6). Surgical technique included 23- and 25-gauge vitrectomy (23:1). Four eyes had sutured sclerotomies, and two had postoperative hypotony <7mmHg. Days to endophthalmitis presentation varied between 1 and 21 (mean 66). Treatment methods included the following: tap and antibiotic injection (n=7), tap, antibiotic injection with subsequent vitrectomy (n=2) and prompt vitrectomy with antibiotics (n=15). Sixteen eyes (66.7%) were culture positive, whereas the other eight cases were culture negative. Anatomical results included evisceration (n=1), phthisis (n=1), and globe intact (n=22). Presenting best corrected visual acuity (BCVA) were hand motion (n=14), light perception (n=7), counting fingers (n=2), and no data (n=1). Functionally 19 eyes (79%) had Snellen VA 0.1; 11 eyes (46%) had VA 0.5 Mean logMar BCVA preoperatively and at the last follow-up were 2.07 +/- 0.6 and 0.79 +/- 0.99, respectively. Conclusions: In spite of good anatomical and functional results, this study showed higher rate of endophthalmitis than the latest reports suggesting that small-gauge vitrectomy has reached the safety level of standard 20-gauge vitrectomy when infectious endophthalmitis is concerned.

Tidskriftsartikel (refereegranskat)abstract
- Objectives: The recovery after tonsil surgery is often troublesome for children and caregivers often feel insecure regarding optimal post-operative care for their children at home. The aim was to study what the current literature reports regarding the effect of post-operative telephone counselling and Internet support on pain and recovery after paediatric tonsil surgery. Method: A systematic literature review was conducted where only randomised clinical trials were included. Outcome measures: Primary outcome measure was pain after surgery. Secondary outcomes also included nausea, anxiety, children's knowledge, use of analgesics, fluid intake and health care service use. Results: Only four studies fulfilled the inclusion criteria. The studies were heterogeneous, rendering a meta-analysis impossible. The results of the included studies showed a possible positive effect on postoperative pain, as well as level of anxiety, use of analgesics, fluid intake and health care service use. However, the studies were few with few included participants. Conclusion: There were indications, but no definitive evidence supporting the positive effect of telephone counselling or Internet-based support on pain and recovery after tonsil surgery in children. More research is needed to further examine these effects. ClinicalTrials.gov 12/03/2017 (NCT03292068). © 2021 The Author(s)

Extended Support Within a Person-Centered Practice After Surgery for Patients With Pituitary Tumors: Protocol for a Quasiexperimental Study.
- 2020
-
Ingår i: JMIR research protocols. - : JMIR Publications Inc.. - 1929-0748. ; 9:7

Tidskriftsartikel (refereegranskat)abstract
- Patients with pituitary tumors often live with lifelong consequences of their disease. Treatment options include surgery, radiotherapy, and medical therapy. Symptoms associated with the tumor or its treatment affect several areas of life. Patients need to adhere to long-term contact with both specialist and general health care providers due to the disease, complex treatments, and associated morbidity. The first year after pituitary surgery constitutes an important time period, with medical evaluations after surgery and decisions on hormonal substitution. The development and evaluation of extended patient support during this time are limited.The aim of this study is to evaluate whether support within a person-centered care practice increases wellbeing for patients with pituitary tumors. Our main hypothesis is that the extended support will result in increased psychological wellbeing compared with the support given within standard of care. Secondary objectives are to evaluate whether the extended support, compared with standard care, will result in (1) better health status, (2) less fatigue, (3) higher satisfaction with care, (4) higher self-efficacy, (5) increased person-centered content in care documentation, and (6) sustained patient safety.Within a quasiexperimental design, patients diagnosed with a pituitary tumor planned for neurosurgery are consecutively included in a pretest-posttest study performed at a specialist endocrine clinic. The control group receives standard of care after surgery, and the interventional group receives structured patient support for 1 year after surgery based on person-centeredness covering self-management support, accessibility, and continuity. A total of 90 patients are targeted for each group.Recruitment into the control group was performed between Q3 2015 and Q4 2017. Recruitment into the intervention group started in Q4 2017 and is ongoing until Q4 2020. The study is conducted according to the Declaration of Helsinki, and the protocol has received approval from a regional ethical review board.This study entails an extensive intervention constructed in collaboration between clinicians, patients, and researchers that acknowledges accessibility, continuity, and self-management support within person-centeredness. The study has the potential to compare standard care to person-centered practice adapted specifically for patients with pituitary tumors and evaluated with a combination of patient-reported outcomes and patient-reported experience measures. Following the results, the person-centered practice may also become a useful model to further develop and explore person-centered care for patients with other rare, lifelong conditions.Researchweb.org. https://www.researchweb.org/is/sverige/project/161671.DERR1-10.2196/17697.

Coagulation factor VIII is vital for increasing global coagulation after physical exercise
- 2019
-
Ingår i: Haemophilia. - : Wiley. - 1351-8216 .- 1365-2516. ; 25:2, s. 86-93
-
Tidskriftsartikel (refereegranskat)abstract
- Background: In a previous smaller study, we found evidence of a diminished global coagulation capacity after maximal exercise in patients with severe haemophilia A (HA). Aim: To validate these results, we repeated the study in a larger cohort. We also examined if the exercise-induced increased levels of von Willebrand factor (VWF) might prolong the effect of factor concentrate administered just before exercise. Methods: We studied individual and global coagulation parameters after maximal physical exercise in 10 persons with severe HA and 10 healthy matched control subjects. Blood samples were taken before, 10 minutes, 60 minutes and 4 hours after exercise. Results: Rotational thromboelastometry (ROTEM) and thrombin generation assay-calibrated automated thrombogram (TGA-CAT) showed significantly increased coagulation capacity after maximal exercise in healthy controls but not in patients with severe HA. VWF antigen and activity levels increased significantly in both groups, whereas FVIII:C only showed a significant increase in the control group. No statistically significant differences were seen between FVIII pharmacokinetic results obtained with and without exercise. Conclusion: Our findings do not support the presence of a FVIII-independent mechanism that increases global coagulation, but rather underscores the importance of FVIII in mediating the increased coagulation capacity seen after exercise. Our results could not support the hypothesis that exercise-induced increased levels of VWF for patients with severe HA lead to a prolonged effect of factor concentrate administered just before exercise.

Association of depressive disorders and dementia with mortality among older people with hip fracture
- 2023
-
Ingår i: BMC Geriatrics. - : BioMed Central (BMC). - 1471-2318. ; 23:1
-
Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Hip fracture (HF) is a significant cause of mortality among older people. Almost half of the patients with HF have dementia, which increases the mortality risk further. Cognitive impairment is associated with depressive disorders (DDs) and both dementia and DDs are independent risk factors for poor outcome after HF. However, most studies that evaluate mortality risk after HF separate these conditions.AIMS: To investigate whether dementia with depressive disorders (DDwD) affects the mortality risk at 12, 24, and 36 months after HF among older people.METHODS: Patients with acute HF (n = 404) were included in this retrospective analysis of two randomized controlled trials performed in orthopedic and geriatric departments. Depressive symptoms were assessed using the Geriatric Depression Scale and cognitive function was assessed using the Mini-Mental State Examination. A consultant geriatrician made final depressive disorder and dementia diagnoses using the Diagnostic and Statistical Manual of Mental Disorders criteria, with support from assessments and medical records. The 12-, 24- and 36-month mortality after HF was analyzed using logistic regression models adjusted for covariates.RESULTS: In analyses adjusted for age, sex, comorbidity, pre-fracture walking ability, and fracture type, patients with DDwD had increased mortality risks at 12 [odds ratio (OR) 4.67, 95% confidence interval (CI) 1.75-12.51], 24 (OR 3.61, 95% CI 1.71-7.60), and 36 (OR 4.53, 95% CI 2.24-9.14) months. Similar results were obtained for patients with dementia, but not depressive disorders, alone.CONCLUSION: DDwD is an important risk factor for increased mortality at 12, 24, and 36 months after HF among older people. Routinely assessments after HF for cognitive- and depressive disorders could identify patients at risk for increased mortality, and enable early interventions.TRIAL REGISTRATION: RCT2: International Standard Randomized Controlled Trial Number Register, trial registration number: ISRCTN15738119.

Pain control after total knee arthroplasty : a randomized trial comparing local infiltration anesthesia and continuous femoral block
- 2011
-
Ingår i: Acta Orthopaedica. - New York : Taylor & Francis. - 1745-3674 .- 1745-3682. ; 82:4, s. 441-447

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND AND PURPOSE: Pain after total knee arthroplasty (TKA) is usually severe, and epidural analgesia or femoral nerve block has been considered to be an effective pain treatment. Recently, local infiltration analgesia (LIA) has become increasingly popular but the outcome of this method regarding the analgesic effect has not been fully evaluated. We compared local infiltration analgesia and femoral block with regard to analgesia and morphine demand during the first 24 h after TKA.METHODS: 40 patients undergoing TKA under spinal anesthesia were randomized to receive femoral nerve block (group F) or peri- and intraarticular infiltration analgesia (group LIA) with a mixture containing ropivacaine, ketorolac, and epinephrine. All patients had access to intravenous patient-controlled analgesia (PCA) with morphine postoperatively. Pain intensity at rest and upon movement was assessed on a numeric rating scale (0-10) on an hourly basis over 24 h if the patients were awake.RESULTS: The average pain at rest was marginally lower with LIA (1.6) than with femoral block (2.2). Total morphine consumption per kg was similar between the 2 groups. Ancillary analysis revealed that 1 of 20 patients in the LIA group reported a pain intensity of > 7 upon movement, as compared to 7 out of 19 in the femoral block group (p = 0.04).INTERPRETATION: Both LIA and femoral block provide good analgesia after TKA. LIA may be considered to be superior to femoral block since it is cheaper and easier to perform.

Tidskriftsartikel (refereegranskat)abstract
- Objective Headache is a common symptom among patients with pituitary tumors, as it is in the general population. The aim of the study was to investigate headache as a symptom in patients with pituitary tumors before and 6 months after endoscopic transsphenoidal surgery (TSS). Design This is a prospective observational cohort study. Setting This study was conducted at university tertiary referral hospital. Participants A total of 110 adult patients underwent endoscopic TSS for pituitary tumors. Main Outcome Measures The Migraine Disability Assessment (MIDAS) questionnaire was used before and 6 months after surgery for the assessment of headache. Clinical variables with potential influence on headache were analyzed. Results Sixty-eight (62%) patients experienced headaches at least once during the 3 months before surgery. Thirty (27%) patients reported disabling headache before surgery, with younger age being an independent associated factor ( p <0.001). In patients with disabling headache before surgery, the median (interquartile range) MIDAS score improved from 78 (27-168) to 16 (2-145; p =0.049), headache frequency decreased from 45 (20-81) to 14 (4-35) days ( p =0.009), and headache intensity decreased from 6 (5-8) to 5 (4-7) ( p =0.011) after surgery. In total, 16 of the 30 (53%) patients reported a clinically relevant improvement and five (17%) a clinically relevant worsening. Four (5%) patients developed new disabling headache. No predictor for postoperative improvement of headache was identified. Conclusion In this prospective study, the results show that disabling headache improves following endoscopic TSS in a subset of patients with pituitary tumors. However, no predictive factors for improvement could be identified.

New child-friendly assessments of food odor identification ability, awareness and use of odor cues
- 2023
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Exposure to food odors has been demonstrated to increase appetite, yet little is known about the role of olfaction in picky eating. Picky eating, the unwillingness to try new foods or eat familiar foods is common among children and linked to a low intake of fruits and vegetables. Objective: To develop two new child-friendly assessment tools, that will be put in use to investigate the relationships between olfaction, picky eating, and, fruit and vegetable liking among children. Methods: The following assessment tools were developed: 1) a test assessing fruit and vegetable odor identification (using food-grade aromas), similar to the validated U-sniff test but also quantifying the liking of the odors 2) a self-reported questionnaire tool assessing the awareness and use of odor cues in everyday life, developed from the interview guide Children’s Olfactory Behaviors in Everyday Life (COBEL). Development and evaluation were performed by conducting cognitive interviews with 20 children (aged 5-13). As a next step, 100 Swedish children aged 9-11 years are recruited to participate in data collection (April/May 2023). Data will also be collected on 1) willingness to consume, and liking of, the corresponding fruit and vegetables in a tasting session 2) general odor identification ability, using the validated U-Sniff test 3) the degree of picky eating and, liking of fruits and vegetables, using questionnaire assessments.

Strukturerad miljödatahantering inom järn- och stålindustri. Etapp 2; Miljöinformationssystem
- 2004
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Det analysarbete som gjorts har i denna etapp har genomförts i samarbete med samma tre typföretag - Höganäs AB, Sandvik Materials Technology samt Ovako Steel AB - som i etapp 1. De tre företagen hanterar vardera en avsevärda mängd miljödata som idag finns utspridd inom organisationerna och lagras i olika system varför sammanställningar försvåras. Det betyder att den miljödata som mäts och beräknas lagras på ett sätt som innebär en irrationell hantering av den samlade miljöinformationen. Den analys som visar att det inom järn- och stålbranschen går att beskriva verksamhetsprocesser på ett enhetligt sätt och att miljödatan som företagen mäter, beräknar och lagrar överensstämmer i mycket stor grad. Baserat på detta har en branschgemensam miljödatastruktur varit möjlig att ta fram. Denna struktur är framtagen för att kunna lagra miljödata för utsläpp till luft, utsläpp till vatten, energianvändning och avfall. Utifrån den miljödatastruktur som arbetats fram och genom diskussioner med representanter för typföretagen i projektet har en översiktlig systemskiss för ett miljöinformationssystem inom järn- och stålindustrin tagits fram. Detta miljöinformationssystem kan vara generellt inom branschen och svara upp mot gemensamma krav på hantering av miljödata.

The registered nurse as a clinical research nurse
- 2023
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: Clinical research studies are important for the developmentof new treatments in healthcare. The quality of clinical research relies on the competence, skills, and knowledge of the research team. Clinical research nurses (CRNs) are important members of clinical research teams as they are responsible for various tasks specified in study procedures. Internationally, nurses have been engaged as CRNs in in many areas of medicine, such as oncological research, for several decades. However, there is a lack of consensus concerning their professional role and a clear work description is lacking. In Sweden, nurses are becoming increasingly involved in research as CRNs, yet the CRN role is undefined as there is no Swedish national competence description that could guide CRNs’ work tasks, requirements for education, and management of ethical issues. Furthermore, the processof becoming a CRN is not understood. Increasing international research into the CRN role has shown that the role differs between countries.There is a lack of Swedish studies, including studies of the process of transitioning from being a registered nurse (RN) to a CRN. Since consensus is lacking concerning the CRN role in Sweden, we need to explore it further and examine how nursing perspectives are influencing it. The overall aim of this thesis was therefore to explore the professional role of CRNs in Sweden and the transition of RNs to being CRNs.Methods: Both quantitative (studies I and II) and qualitative (studies III and IV) methods were used. The analyses are based on data from questionnaires and individual interviews of CRNs in Sweden. In study I, descriptive statistics and test–retest analyses were used to analyze the validity and reliability of the translated CTNQ-SWE. In study II, descriptive statistics and one-way ANOVA were used to analyze reported work tasks, perceptions, and differences between groups of CRNs. In studies III and IV, qualitative content analysis according to Graneheimet al., (2004) was used to analyze the transition, i.e., becoming and being a CRN.Results: CRNs perform new and diverse work tasks and are often involved throughout the study process, with the greatest activity in data management and the actual conducting and evaluation of clinical studies (e.g., scheduling and performing procedures and tests according to the research protocols). There is seldom any work description or competence framework to guide nurses through the transition to the CRN role, placing them in an uncertain position where they must struggle to adaptiv to their new role and work tasks. To perform these new work activities, CRNs need more support as well as education in research procedures, regulations, and ethics. During the transition, CRNs improve their knowledge of research, regulations, and ethics and increase their experience of clinical research practice and collaboration in networks. They also learn and develop from dealing with challenging situations, such as the informed consent process. Furthermore, problem solving, study requirements, and ethical reasoning are emphasized as challenging. When passing through the different phases of transition to the CRN role, the nurses achieve expanded competence, change didentity, and growing confidence as informal leaders. CRNs also advocate for patient rights and mentor others involved in research, but they simultaneously lack acknowledgement and a formal leadership role.Conclusions and clinical implications: This thesis provides important insights into the CRN role in Sweden. It highlights the transition of RNs to becoming CRNs as well as their experiences of working as and becoming CRNs. The thesis reports that CRNs, overall, seem to be satisfied with their work, but some of their experiences highlight that skills, education, and organizational structures require improvement; forexample, appropriate introduction and support are required during the transition to the CRN role. Ethical challenges call for ongoing discussion in research teams. One conclusion is that CRNs’ competences and tasks need to be clarified. Developing clear competence pathways for nurses to become CRNs, including mentorship and support, could be one way of acknowledging CRNs’ important work, thereby creating a better outlook for high-quality clinical research procedures. Making the CRN professional title more homogeneous nationally and internationally would make comparisons easier. This would clarify CRNs’ work tasks and role in Sweden and extend the nursing perspective on ethics. This thesis adds to a slowly growing body of literature on the CRN role and is relevant to both practitioners and policymakers. Additionally, it illustrates a need to develop both educational and mentoring support aswell as career pathways for RNs to become CRNs, which could improve the quality of clinical research in Sweden.

Tidskriftsartikel (refereegranskat)abstract
- Incomplete inversion of the hippocampus, an imperfect fetal development, has been described in patients with epilepsy or severe midline malformations. We studied this condition in a nonepileptic population without obvious developmental anomalies. We analyzed the coronal MR images of 50 women and 50 men who did not have epilepsy. Twenty of them were healthy volunteers and 80 were patients without obvious intracranial developmental anomalies, intracranial masses, hydrocephalus or any condition affecting the temporal lobes. If the entire hippocampus (the head could not be evaluated) were affected, the incomplete inversion was classified as total, otherwise as partial. Incomplete inversion of the hippocampus was found in 19/100 subjects (9 women, 10 men). It was unilateral, always on the left side, in 13 subjects (4 women, 9 men): 9 were of the total type, 4 were partial. It was bilateral in six subjects (five women, one man): four subjects had total types bilaterally, two had a combination of total and partial types. The collateral sulcus was vertically oriented in all subjects with a deviating hippocampal shape. We conclude that incomplete inversion of the hippocampus is not an unusual morphologic variety in a nonepileptic population without other obvious intracranial developmental anomalies.

- Relevant for various areas of human genetics, Y-chromosomal short tandem repeats (Y-STRs) are commonly used for testing close paternal relationships among individuals and populations, and for male lineage identification. However, even the widely used 17-loci Yfiler set cannot resolve individuals and populations completely. Here, 52 centers generated quality-controlled data of 13 rapidly mutating (RM) Y-STRs in 14,644 related and unrelated males from 111 worldwide populations. Strikingly, greater than99% of the 12,272 unrelated males were completely individualized. Haplotype diversity was extremely high (global: 0.9999985, regional: 0.99836-0.9999988). Haplotype sharing between populations was almost absent except for six (0.05%) of the 12,156 haplotypes. Haplotype sharing within populations was generally rare (0.8% nonunique haplotypes), significantly lower in urban (0.9%) than rural (2.1%) and highest in endogamous groups (14.3%). Analysis of molecular variance revealed 99.98% of variation within populations, 0.018% among populations within groups, and 0.002% among groups. Of the 2,372 newly and 156 previously typed male relative pairs, 29% were differentiated including 27% of the 2,378 father-son pairs. Relative to Yfiler, haplotype diversity was increased in 86% of the populations tested and overall male relative differentiation was raised by 23.5%. Our study demonstrates the value of RMY-STRs in identifying and separating unrelated and related males and provides a reference database.

Proposal of a New Tool for Pre-Straining Operations of Sheet Metals and an Initial Investigation of CR4 Mild Steel Formability

Tidskriftsartikel (refereegranskat)abstract
- With the increased focus on reducing carbon emissions in the automotive industry, more advanced materials are introduced to reduce the vehicle weight, and more complex component geometries are designed to both satisfy customer demands and to optimize the vehicle aerodynamically. With the increase in component complexity, the strain paths produced during the forming operation of car body components often display a highly non-linear behavior which makes the task of failure prediction during the manufacturing feasibility studies more difficult. Therefore, CAE engineers need better capabilities to predict failure induced by strain path nonlinearity. This study proposes a new tool designed for creating bi-linear strain paths, by performing a pre-strain of a sheet large enough to cut out Nakajima specimens to perform the post-straining in any direction. From five pre-straining tests the tool present a stable pre-straining operation with a uniform strain field in a radius of 100 [mm] from the centre, corresponding to the region of interest of a Nakajima specimen. From the five pre-strained samples, different Nakajima specimens are cut transverse and longitudinal to the rolling direction and a failure prediction approach in an alternative, path independent evaluation space was used to predict the onset of necking with promising results.

- Aims. The aim of this work is to characterise HCN and CH3OH emission from recent comets. Methods. We used the Onsala 20-m telescope to search for millimetre transitions of HCN towards a sample of 11 recent and mostly bright comets in the period from December 2016 to November 2019. Also, CH3OH was searched for in two comets. The HCN sample includes the interstellar comet 2I/Borisov. For the short-period comet 46P/Wirtanen, we were able to monitor the variation of HCN emission over a time-span of about one month. We performed radiative transfer modelling for the observed molecular emission by also including time-dependent effects due to the outgassing of molecules. Results. HCN was detected in six comets. Two of these are short-period comets and four are long-period. Six methanol transitions were detected in 46P/Wirtanen, enabling us to determine the gas kinetic temperature. From the observations, we determined the molecular production rates using time-dependent radiative transfer modelling. For five comets, we were able to determine that the HCN mixing ratios lie near 0.1% using contemporary water production rates, Q(H2O), taken from other studies. This HCN mixing ratio was also found to be typical in our monitoring observations of 46P/Wirtanen but here we notice deviations of up to 0.2% on a daily timescale which could indicate short-time changes in outgassing activity. From our radiative transfer modelling of cometary comae, we find that time-dependent effects on the HCN level populations are of the order of 5-15% when Q(H2O) is around 2 x 10(28) mol s(-1). The effects may be stronger for comets with lower Q(H2O). The exact details of the time-dependent effects depend on the amount of neutral and electron collisions, radiative pumping, and molecular parameters such as the spontaneous rate coefficient.

- BACKGROUND: Exercise lowers blood pressure and improves cardiovascular function, but little is known about whether exercise impacts cardiovascular morbidity and mortality independent of left ventricular hypertrophy (LVH) and LV geometry. DESIGN: Observational analysis of prospectively obtained echocardiographic data within the context of a randomized trial of antihypertensive treatment. METHODS: A total of 937 hypertensive patients with ECG LVH were studied by echocardiography in the Losartan Intervention For Endpoint reduction in hypertension study. Baseline exercise status was categorized as sedentary (never exercise), intermediate (30 min twice/week). During 4.8-year follow-up, 105 patients suffered the primary composite endpoint of myocardial infarction (MI), stroke, or cardiovascular death. MI occurred in 39, stroke in 60, and cardiovascular death in 33 patients. RESULTS: Sedentary individuals (n = 212) had, compared with those physically active (n = 511), higher heart rate (P<0.001), weight (P<0.001), body surface area (P = 0.02), body mass index (P<0.001), LV mass (LVM, P = 0.04), LVM indexed for height or body surface area (P = 0.004); thicker ventricular septum (P = 0.012) and posterior wall (P = 0.016); and larger left atrium (P = 0.006). Systolic variables did not differ. In Cox regression analysis, physically active compared with sedentary patients had lower risk of primary composite endpoint [odds ratio (OR): 0.42, 95% confidence interval (CI): 0.26-0.68, P < 0.001], cardiovascular death (OR: 0.50, 95% CI: 0.22-0.1.10, NS), and stroke (OR: 0.26, 95% CI: 0.13-0.49, P < 0.001) without significant difference for MI (OR: 0.79, 95% CI: 0.35-1.75, NS) independent of systolic blood pressure, LVM index, or treatment. CONCLUSION: In hypertensive patients with LVH, physically active patients had improved prognosis for cardiovascular endpoints, mortality, and stroke that was independent of LVM.

- Evidence indicates a link between exposure to ambient air pollution and decreased female fertility. The ability of air pollution particles to reach human ovarian tissue and follicles containing the oocytes in various maturation stages has not been studied before. Particulate translocation might be an essential step in explaining reproductive toxicity and assessing associated risks. Here, we analysed the presence of ambient black carbon particles in (i) follicular fluid samples collected during ovum pick-up from 20 women who underwent assisted reproductive technology treatment and (ii) adult human ovarian tissue from 5 individuals. Follicular fluid and ovarian tissue samples were screened for the presence of black carbon particles from ambient air pollution using white light generation by carbonaceous particles under femtosecond pulsed laser illumination. We detected black carbon particles in all follicular fluid (n = 20) and ovarian tissue (n = 5) samples. Black carbon particles from ambient air pollution can reach the ovaries and follicular fluid, directly exposing the ovarian reserve and maturing oocytes. Considering the known link between air pollution and decreased fertility, the impact of such exposure on oocyte quality, ovarian ageing and fertility needs to be clarified urgently.

- BackgroundCognitive impairment and psychological distress are common in intensive care unit (ICU) survivors. Early identification of affected individuals is important, so intervention and treatment can be utilized at an early stage. Cognitive Failures Questionnaire (CFQ) is commonly used to screen for subjective cognitive function, but it is unclear whether CFQ scores correlate to objective cognitive function in this population.MethodsBetween 2014 and 2018, 100 ICU survivors aged 18–70 years from the general ICU at the Karolinska University Hospital, Solna, were included in the study. Out of these, 58 patients completed follow-up at 3 months after ICU discharge, 51 at 6 months, and 45 at 12 months. Follow-up included objective cognitive function testing using the Cambridge Neuropsychological Test Automated Battery (CANTAB) and subjective cognitive function testing with the self-rating Cognitive Failures Questionnaire (CFQ), as well as psychological self-rating with the Post-Traumatic Stress Symptoms Scale-10 (PTSS-10) and Hospital Anxiety and Depression Scale (HADS).ResultsThe prevalence of cognitive impairment as measured by four selected CANTAB tests was 34% at 3 months after discharge, 18% at 6 months, and 16% at 12 months. There was a lack of significant correlation between CANTAB scores and CFQ scores at 3 months (r = − 0.134–0.207, p > 0.05), at 6 months (r = − 0.106–0.257, p > 0.05), and at 12 months after discharge (r = − 0.070–0.109, p > 0.05). Correlations between CFQ and PTSS-10 scores and HADS scores, respectively, were significant over the follow-up period (r = 0.372–0.710, p ≤ 0.001–0.023). In contrast, CANTAB test scores showed a weak correlation with PTSS-10 and HADS scores, respectively, at 3 months only (r = − 0.319–0.348, p = 0.008–0.015).ConclusionWe found no clinically relevant correlation between subjective and objective cognitive function in this cohort of ICU survivors, while subjective cognitive function correlated significantly with psychological symptoms throughout the follow-up period. Treatment and evaluation of ICU survivors’ recovery need to consider both subjective and objective aspects of cognitive impairment, and subjective reports must be interpreted with caution as an indicator of objective cognitive function.

- CONCLUSION: The olfactory event-related potential (OERP) method provides a means of objectively assessing olfactory function. However, further validation is needed before OERPs can be routinely applied in clinical assessment of olfactory dysfunction. OBJECTIVE: To assess OERPs in patients with olfactory impairment and in healthy controls to investigate possible dose-response effects of odor concentration on OERP parameters in these groups, thereby exploring possibilities and limitations regarding the clinical utility of the OERP method. SUBJECTS AND METHODS: Twenty-three patients with a history of impaired olfactory function and 24 controls participated in the study. Olfactory function was assessed with psychophysical tests, i.e. assessment of the odor threshold, and odor identification. OERPs were obtained in response to the olfactory stimulant butanol at two different concentrations, presented via an olfactometer. RESULTS: The OERP amplitudes increased and the latencies shortened with increasing stimulus concentration. Furthermore, a difference between the groups was found, with higher OERP amplitudes and shorter latencies in healthy subjects compared with patients.

- Environmental change has a human dimension, and has had so for at least the last 10 000 years. The prehistoric impact of people on the Arctic landscape has occasionally left visible traces, such as house and field structures. More often than not, however, the only evidence available is at the microscopic or geochemical level, such as fossil insect and seed assemblages or changes in the physical and chemical properties of soils and sediments. These records are the subject of SEAD, a multidisciplinary database and software project currently underway at Umeå University, Sweden, which aims to create an online database and set of tools for investigating these traces, as part of an international research infrastructure for palaeoecology and environmental archaeology.

Tidskriftsartikel (refereegranskat)abstract
- BackgroundGrowing care queues, reduced access to care and cancelled surgery are realities for some patients being treated with total hip or knee replacement surgery in Sweden.Most of the patients on the waiting lists have experienced pain and limited motion for a varying period of time, with a negative effect on their everyday lives. Overbooked surgical schedules are already contributing to the lengthy waiting times, but, with the addition of cancellations, longer waiting times will increase still further and may affect patients’ well‐being.MethodsIn the present study, we aimed to illuminate the experience of having planned surgery cancelled, based on narratives from 10 participants. The interview transcriptions were analysed using a phenomenological hermeneutic approach.ResultsThe comprehensive analyses revealed that the participants described the agony of being deselected and the additional impression of being excluded. Metaphors of being damaged and feeling physical pain were used and the interpretations referred to the cancellations as unpleasant. Additionally, the important relationship and the trust between the health workers and the patient were negatively affected by the cancellation.ConclusionAfter the cancellation, the participants expressed being vulnerable and from their perspective the cancelled surgery affected them deeply; in fact, much more than the healthcare workers appeared to understand. Therefore, information around the cancellation must be given respectfully and with dignity, in a dialogue between the patient and the healthcare workers. Taken together, to enable an opportunity to be involved in the continued care. The cancellations should be seen as an interruption, in which the patients’ chance of living a pain‐free, active life is postponed.

- The subarctic environment of northernmost Sweden has changed over the past century, particularly elements of climate and cryosphere. This paper presents a unique geo-referenced record of environmental and ecosystem observations from the area since 1913. Abiotic changes have been substantial. Vegetation changes include not only increases in growth and range extension but also counterintuitive decreases, and stability: all three possible responses. Changes in species composition within the major plant communities have ranged between almost no changes to almost a 50 per cent increase in the number of species. Changes in plant species abundance also vary with particularly large increases in trees and shrubs (up to 600%). There has been an increase in abundance of aspen and large changes in other plant communities responding to wetland area increases resulting from permafrost thaw. Populations of herbivores have responded to varying management practices and climate regimes, particularly changing snow conditions. While it is difficult to generalize and scale-up the site-specific changes in ecosystems, this very site-specificity, combined with projections of change, is of immediate relevance to local stakeholders who need to adapt to new opportunities and to respond to challenges. Furthermore, the relatively small area and its unique datasets are a microcosm of the complexity of Arctic landscapes in transition that remains to be documented.

On the ubiquity of molecular anions in the dense interstellar medium
- 2013

- Results are presented from a survey for molecular anions in seven nearby Galactic star-forming cores and molecular clouds. The hydrocarbon anion C6H- is detected in all seven target sources, including four sources where no anions have been previously detected: L1172, L1389, L1495B, and TMC-1C. The C6H-/C6H column density ratio is greater than or similar to 1.0% in every source, with a mean value of 3.0% (and standard deviation 0.92%). Combined with previous detections, our results show that anions are ubiquitous in dense clouds wherever C6H is present. The C6H-/C6H ratio is found to show a positive correlation with molecular hydrogen number density, and with the apparent age of the cloud. We also report the first detection of C4H- in TMC-1 (at 4.8 sigma confidence), and derive an anion-to-neutral ratio C4H-/C4H = (1.2 +/- 0.4) x 10(-5)(= 0.0012% +/- 0.0004%). Such a low value compared with C6H- highlights the need for a revised radiative electron attachment rate for C4H. Chemical model calculations show that the observed C4H- could be produced as a result of reactions of oxygen atoms with C5H- and C6H-.

- Foot drop (FD) can be caused by a variety of diseases and injuries. FD leads to walking difficulties and reduced balance which also can lead to a higher risk of falling. Patient with a stroke often have an equinovarus deformity of the foot together with the DF. There is a need to optimize and standardize the treatment for patients with FD across different medical specialities. Surgical interventions, with goals of producing a balanced functional foot, have been shown to improve the function and quality of life and decrease the use of braces and walking aids in patients with FD after a CVI. In Sweden data regarding FD surgery is collected in the National Quality Registry for Foot and Ankle Surgery (Riksfot), but there is also an ongoing multicentre study, investigating the patient-reported and functional results of surgery due to FD caused by a CVI.

Individual tree detection and estimation of stem attributes with mobile laser scanning along boreal forest roads
- 2022
-
Ingår i: ISPRS Journal of Photogrammetry and Remote Sensing. - : Elsevier BV. - 0924-2716. ; 187, s. 211-224

Tidskriftsartikel (refereegranskat)abstract
- The collection of field-reference data is a key task in remote sensing-based forest inventories. However, traditional methods of collection demand extensive personnel resources. Thus, field-reference data collection would benefit from more automated methods. In this study, we proposed a method for individual tree detection (ITD) and stem attribute estimation based on a car-mounted mobile laser scanner (MLS) operating along forest roads. We assessed its performance in six ranges with increasing mean distance from the roadside. We used a Riegl VUX1LR sensor operating with high repetition rate, thus providing detailed cross sections of the stems. The algorithm we propose was designed for this sensor configuration, identifying the cross sections (or arcs) in the point cloud and aggregating those into single trees. Furthermore, we estimated diameter at breast height (DBH), stem profiles, and stem volume for each detected tree. The accuracy of ITD, DBH, and stem volume estimates varied with the trees' distance from the road. In general, the proximity to the sensor of branches 0-10 m from the road caused commission errors in ITD and over estimation of stem attributes in this zone. At 50-60 m from roadside, stems were often occluded by branches, causing omissions and underestimation of stem attributes in this area. ITD's precision and sensitivity varied from 82.8% to 100% and 62.7% to 96.7%, respectively. The RMSE of DBH estimates ranged from 1.81 cm (6.38%) to 4.84 cm (16.9%). Stem volume estimates had RMSEs ranging from 0.0800 m(3) (10.1%) to 0.190 m(3) (25.7%), depending on the distance to the sensor. The average proportion of detected reference volume was highly affected by the performance of ITD in the different zones. This proportion was highest from 0 to 10 m (113%), a zone that concentrated most ITD commission errors, and lowest from 50 to 60 m (66.6%), mostly due to the omission errors in this area. In the other zones, the RMSE ranged from 87.5% to 98.5%. These accuracies are in line with those obtained by other state-of-the-art MLS and terrestrial laser scanner (TLS) methods. The car-mounted MLS system used has the potential to collect data efficiently in large-scale inventories, being able to scan approximately 80 ha of forests per day depending on the survey setup. This data collection method could be used to increase the amount of field-reference data available in remote sensing based forest inventories, improve models for area-based estimations, and support precision forestry development.

Perspectives on Sexuality Among Patients with Hypopituitarism: Broadening the Medical Focus on Sexual Function to Include Sexual Wellbeing
- 2020

- Hypopituitarism means a partial or complete inability to produce pituitary hormones, including those regulating gonadal function. The condition therefore leads to hormone deficiencies that may affect sexuality in various ways. This study aimed to explore patients' own experiences of hypopituitarism in relation to sexuality, and it is based on interviews with 19 men and women. A qualitative methodology inspired by Gadamer's philosophical hermeneutics was used. Analysis revealed that current healthcare practices, which focus primarily on sexual functioning, fail to address patients' existential concerns about loneliness, loving relationships and selfhood. Another important finding was that women felt that their sexual functioning and wellbeing tended to go unnoticed, while men said that healthcare professionals focused mainly on erectile function rather than problems with sexual wellbeing. Cultural and gender norms were apparent in these healthcare interactions, and proactive efforts to improve awareness is required in order to improve the quality of care provided to these patients. Healthcare professionals need time, space and support for reflection so that they may enhance their knowledge about the complexity of sexuality and discuss the results of research into hormone replacement in men and women. They also need support to develop critical awareness of how gendered norms about sexuality may negatively affect the care provided to persons with hypopituitarism.

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Forskargruppen KRIHS, Kris och risk i det heterogena samhället, har fått uppdraget att skriva en kunskapsöversikt inom ramen för MSB:s verksamhetsområden skydd mot olyckor, krishantering och civil beredskap. Uppdraget har gjorts i samarbete med Eva-Lena Demarin som stått för stora delar av sammanställningen av tidigare forskning samt delar av övriga avsnitt. Undertecknad ansvarar för översiktens vetenskapliga kvalitet. Kunskapsöversikten är dock ett resultat av forskargruppens gemensamma ansträngningar. Tillsammans med Eva-Lena har gruppen träffats vid fem tillfällen varav vid ett seminarium där texten diskuterats och reviderats. De som varit med och diskuterat, samlat in material och/eller skrivit delar av översikten är förutom ovan nämnda, Erna Danielsson, Sara Ekholm, Linda Eliasson, Roine Johansson, Jörgen Sparf, Erika Wall och Susanna Öhman.Då både tiden och utrymmet har varit begränsat gör vi inga anspråk på att kunskapsöversikten är heltäckande. Den ska snarare ses som en ganska grovkorning bild av de senaste tio årens risk- och krisforskning rörande uppfattningar, kommunikation och organisation. Det huvudsakliga bidraget är att översikten identifierar vissa områden där kunskapsuppbyggnad behövs. På så sätt kan översikten ses som en karta där vissa kompassriktningar markerats utifrån vilka MSB kan välja vilka som passar myndighetens framtida verksamhet.

Investigation of Structural Features of Two Related Lipases and the Impact on Fatty Acid Specificity in Vegetable Fats
- 2022
-
Ingår i: International Journal of Molecular Sciences. - : MDPI AG. - 1422-0067. ; 23:13

Tidskriftsartikel (refereegranskat)abstract
- One of the indispensable applications of lipases in modification of oils and fats is the possibility to tailor the fatty acid content of triacylglycerols (TAGs), to meet specific requirements from various applications in food, nutrition, and cosmetic industries. Oleic acid (C18:1) and stearic acid (C18:0) are two common long fatty acids in the side chain of triglycerides in plant fats and oils that have similar chemical composition and structures, except for an unsaturated bond between C9 and C10 in oleic acid. Two lipases from Rhizomucor miehei (RML) and Rhizopus oryzae (ROL), show activity in reactions involving oleate and stearate, and share high sequence and structural identity. In this research, the preference for one of these two similar fatty acid side chains was investigated for the two lipases and was related to the respective enzyme structure. From transesterification reactions with 1:1 (molar ratio) mixed ethyl stearate (ES) and ethyl oleate (EO), both RML and ROL showed a higher activity towards EO than ES, but RML showed around 10% higher preference for ES compared with ROL. In silico results showed that stearate has a less stable interaction with the substrate binding crevice in both RML and ROL and higher tendency to freely move out of the substrate binding region, compared with oleate whose structure is more rigid due to the existence of the double bond. However, Trp88 from RML which is an Ala at the identical position in ROL shows a significant stabilization effect in the substrate interaction in RML, especially with stearate as a ligand.

Is the P600/affected by the richness of semantic content? : a linguistic ERP study in Swedish
- 2008
-
Ingår i: Scandinavian Journal of Psychology. - : Wiley. - 0036-5564. ; 49, s. 1-9
-
Tidskriftsartikel (refereegranskat)abstract
- The study investigated whether the P600/SPS component is sensitive to the richness of semantic content in sentences. ERPs were recorded while 30 native Swedish speakers read sentences, of which half were syntactically correct and half contained a syntactic violation. Both kinds of sentences came in one of three types of descending semantic completeness: semantically coherent sentences, sentences which were incoherent due to violations of selectional restrictions, or sentences of pseudo words, hence void of lexical content. In the semantically coherent sentences a P600/SPS was found for the syntactic violation. A less salient positivity was found for the violation in the semantically incoherent sentences. No P600/SPS was found for the syntactic violation in the pseudo word sentences and no LAN component in any sentence type. The results are interpreted as supporting the hypothesis that the P600/SPS component reflects a semantically based reanalysis process.
