- Self-care is important for heart failure patients. However, what are the views of patients on their situation when it comes to realizing self-care? The aim of the paper is to investigate the self-care needs of HF patients, by understanding the issues they embrace in their self-care processes. In this paper we make a review of 17 interviews and make a classification of what the needs are for possible information technology support systems. Based on the analysis of these interviews, we identify the diversity of needs in support of activities related to different background conditions and the dynamics of change of learning and changes in the heart failure condition. The contribution of the paper is a framework for understanding the diversity of needs and the specific situations of this group of patients.

Konferensbidrag (refereegranskat)abstract
- The paper deals with the planning of eHealth systems in the area of chronic care from a patient-centred perspective. The particular area is heart failure (HF) and systems that support patients’ possibilities to be active learners during the care processes. A better understanding of this process is hoped to create a basis for the development of appropriate information systems or information technology (IS/IT) support of learning processes. The objective of this paper is the development of a better understanding of the challenges of chronic illness with special focus on HF. The results are presented as a planning framework that guides the choice and design of ICT-based support systems.

Tidskriftsartikel (refereegranskat)abstract
- Objective: This study aimed to investigate whether reported high mortality in childhood recombinant human GH (rhGH)-treated patients was related to birth-characteristics and/or rhGH treatment. Design and Setting: We sought to develop a mortality model of the Swedish general population born between 1973 and 2010, using continuous-hazard functions adjusting for birth characteristics, sex, age intervals, and calendar year to estimate standardized mortality ratio (SMR) and to apply this model to assess expected deaths in Swedish rhGH-treated patients with idiopathic isolated GH deficiency (IGHD), idiopathic short stature (155) or born small for gestational age (SGA). Participants:The general population: Swedish Medical Birth Register (1973-2010: 1 880 668 males; 1 781 131 females) and Cause of Death Register (1985-2010). Intervention Population: Three thousand eight hundred forty-seven patients starting rhGH treatment between 1985 and 2010 and followed in the National GH Register and/or in rhGH trials diagnosed with IGHD (n = 1890), ISS (n = 975), or SGA (n=982). Main Outcome Measures: Death. Results: Using conventional models adjusting for age, sex, and calendar-year, the SMR was 1.43 (95% confidence interval, 0.89-2.19), P = .14, observed/expected deaths 21/14.68. The rhGH population differed (P amp;lt; .001) from the general population regarding birth weight, birth length, and congenital malformations. Application of an Advanced Model: When applying the developed mortality model of the general population, the ratio of observed/expected deaths in rhGH-treated patients was 21/21.99; SMR = 0.955 (0.591-1.456)P = .95. Model Comparison: Expected number of deaths were 14.68 (14.35-14.96) using the conventional model, and 21.99 (21.24-22.81) using the advanced model, P amp;lt; .001, which had at all ages a higher gradient of risk per SD of the model, 24% (range, 18-42%; P amp;lt; .001). Conclusions: Compared with the general Swedish population, the ratio of observed/expected deaths (21/21.99) was not increased in childhood rhGH-treated IGHD, ISS, and SGA patients when applying an advanced sex-specific mortality model adjusting for birth characteristics.

A scoping review and mapping exercise comparing the content of patient-reported outcome measures (PROMs) across heart disease-specific scales
- 2020
-
Ingår i: Journal of Patient-Reported Outcomes. - : Springer. - 2509-8020. ; 4:1
-
Forskningsöversikt (refereegranskat)abstract
- BACKGROUND: Over the past decade, the importance of person-centered care has led to increased interest in patient-reported outcome measures (PROMs). In cardiovascular care, selecting an appropriate PROM for clinical use or research is challenging because multimorbidity is often common in patients. The aim was therefore to provide an overview of heart-disease specific PROMs and to compare the content of those outcomes using a bio-psycho-social framework of health.METHODS: A scoping review of heart disease-specific PROMs, including arrhythmia/atrial fibrillation, congenital heart disease, heart failure, ischemic heart disease, and valve diseases was conducted in PubMed (January 2018). All items contained in the disease-specific PROMs were mapped to WHO's International Classification of Functioning, Disability and Health (ICF) according to standardized linking rules.RESULTS: A total of 34 PROMs (heart diseases in general n = 5; cardiac arrhythmia n = 6; heart failure n = 14; ischemic heart disease n = 9) and 147 ICF categories were identified. ICF categories covered Body functions (n = 61), Activities & Participation (n = 69), and Environmental factors (n = 17). Most items were about experienced problems of Body functions and less often about patients' daily activities, and most PROMs were specifically developed for heart failure and no PROM were identified for valve disease or congenital heart disease.CONCLUSIONS: Our results motivate and provide information to develop comprehensive PROMs that consider activity and participation by patients with various types of heart disease.

Collagen epitope expression on B cells is sufficient to confer tolerance to collagen-induced arthritis
- 2016
-
Ingår i: Arthritis Research & Therapy. - : Springer Science and Business Media LLC. - 1478-6362. ; 18
-
Tidskriftsartikel (refereegranskat)abstract
- Background: The mechanisms underlying tolerance induction and maintenance in autoimmune arthritis remain elusive. In a mouse model of rheumatoid arthritis, collagen type II (CII)-induced arthritis, we explore the contribution of B cells to antigen-specific tolerance. Methods: To generate expression of the CII-peptide specifically on B-cell major histocompatibility complex type II, lentiviral-based gene therapy including a B-cell-specific Igk promoter was used. Results: Presentation of the CII-peptide on B cells significantly reduced the frequency and severity of arthritis as well as the serum levels of CII -specific IgG antibodies. Further, both frequency and suppressive function of regulatory T cells were increased in tolerized mice. Adoptive transfer of regulatory T cells from tolerized mice to naive mice ameliorated the development of CII-induced arthritis. Conclusion: Our data suggest that endogenous presentation of the CII-peptide on B cells is one of the key contributors to arthritis tolerance induction and maintenance.

Autonomous Avoidance Maneuvers for Vehicles using Optimization
- 2021
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- To allow future autonomous passenger vehicles to be used in the same driving situations and conditions as ordinary vehicles are used by human drivers today, the control systems must be able to perform automated emergency maneuvers. In such maneuvers, vehicle dynamics, tire–road interaction, and limits on what the vehicle is capable of performing are key factors to consider. After detecting a static or moving obstacle, an avoidance maneuver or a sequence of lane changes are common ways to mitigate the critical situation. For that purpose, motion planning is important and is a primary task for autonomous-vehicle control subsystems. Optimization-based methods and algorithms for such control subsystems are the main focus of this thesis.Vehicle-dynamics models and road obstacles are included as constraints to be fulfilled in an optimization problem when finding an optimal control input, while the available freedom in actuation is utilized by defining the optimization criterion. For the criterion design, a new proposal is to use a lane-deviation penalty, which is shown to result in well-behaved maneuvers and, in comparison to minimum-time and other lateral-penalty objective functions, decreases the time that the vehicle spends in the opposite lane.It is observed that the final phase of a double lane-change maneuver, also called the recovery phase, benefits from a dedicated treatment. This is done in several steps with different criteria depending on the phase of the maneuver. A theoretical redundancy analysis of wheel-torque distribution, which is derived independently of the optimization criterion, complements and motivates the suggested approach.With a view that a complete maneuver is a sequence of two or more sub-maneuvers, a decomposition approach resulting in maneuver segments is proposed. The maneuver segments are shown to be possible to determine with coordinated parallel computations with close to optimal results. Suitable initialization of segmented optimizations benefits the solution process, and different initialization approaches are investigated. One approach is built upon combining dynamically feasible motion candidates, where vehicle and tire forces are important to consider. Such candidates allow addressing more complicated situations and are computed under dynamic constraints in the presence of body and wheel slip. To allow a quick reaction of the vehicle control system to moving obstacles and other sudden changes in the conditions, a feedback controller capable of replanning in a receding-horizon fashion is developed. It employs a coupling between motion planning using a friction-limited particle model and a novel low-level controller following the acceleration-vector reference of the computed plan. The controller is shown to have real-time performance.

Day-to-day Rationing of Limited Resources in Swedish routine Primary Care : an interview study
- 2013
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Background: Rationing is a reality in all health care, but little is known about day-to-day rationing in routine primary health care (PHC). This study aims to explore strategies to handle limited of resources in Swedish routine primary care.Methods: Data were compiled from 62 interviews with healthcare professionals (general practitioners, nurses, physiotherapists, and managers at primary care centres). A qualitative research method was applied in the analysis.Results: The interviewed staff described perceptions of a general public with high expectations on PHC in combination with a lack of resources. Strategies to cope with scarce resources were avoiding rationing, ad hoc rationing, or planned rationing. Rationing was largely implicit and not based on ethical principles or other defined criteria. Trying to avoid rationing resulted in unintended rationing. Ad hoc rationing had undesired consequences, e.g. inadequate continuity of care and displacing certain patient groups, especially the chronically ill and the elderly. The staff expressed a need for support and for applicable guidelines, and called for policy statements based on priority decisions to help manage the situation.Conclusions: The interviews suggested a need to improve the transparency of priority setting procedures in PHC, although the nature of the PHC setting presents special challenges. Improving transparency could, in turn, improve equity and the efficient use of resources in PHC.

Tidskriftsartikel (refereegranskat)abstract
- Background: Nurses represent the largest sector of the workforce caring for people with cardiovascular disease in Europe. Little is known about the post-registration education provided to nurses working within this specialty. The aim of this descriptive cross sectional survey was to describe the structure, content, teaching, learning, assessment and evaluation methods used in post-registration cardiovascular nurse education programmes in Europe.Method: A 24-item researcher generated electronic questionnaire was sent to nurse representatives from 23 European countries. Items included questions about cardiovascular registered nurse education programmes.Results: Forty-nine respondents from 17 European countries completed questionnaires. Respondents were typically female (74%) and educated at Masters (50%) or doctoral (39%) level. Fifty-one percent of the cardiovascular nursing education programmes were offered by universities either at bachelor or masters level. The most frequently reported programme content included cardiac arrhythmias (93%), heart failure (85%) and ischaemic heart disease (83%). The most common teaching mode was face-to-face lectures (85%) and/or seminars (77%). A variety of assessment methods were used with an exam or knowledge test being the most frequent. Programme evaluation was typically conducted through student feedback (95%).Conclusion: There is variability in the content, teaching, learning and evaluation methods in post-registration cardiovascular nurse education programmes in Europe. Cardiovascular nurse education would be strengthened with a stronger focus upon content that reflects current health challenges faced in Europe. A broader view of cardiovascular disease to include stroke and peripheral vascular disease is recommended with greater emphasis on prevention, rehabilitation and the impact of health inequalities.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The purpose of this study was to test practical skills of cardiopulmonary resuscitation (CPR) in European cardiovascular nurses and allied professions. Methods: Eighty-six delegates at the Spring Meeting on Cardiovascular Nursing in Malmö, Sweden, in 2008, were recruited for this study. Laerdal Resusci Anne SkillReporter manikins connected to a computer with the Laerdal PC SkillReporting System were used. The participants were told to perform CPR according to the “new”guidelines from 2005; 30:2 for three minutes. Results: 88% of the tested participants were nurses and 79% were female. Mean age were 42 years (range 19–63 years). They came from 14 different European countries, though one third was from Sweden. About two thirds had trained CPR within the last year. Seven per cent had no previous CPR training. According to practical skills the average inflations per minute were five (SD+1.5), average inflation volume 992 ml (SD+423) and average flow rate 857 ml/second (SD+401). According assessment of chest compressions the average compression rate was 121 (SD+22.5), average compression per minute 79.5 (SD+14.4), average compression depth 43.8 mm (SD+9.4) and average compression duty cycle 43.8% (SD+5.7). Hand position “too low”was the most common committed error. Conclusion: The practical skill in CPR among the tested delegates was rather satisfying regarding chest compressions. However, there were wide ranges as shown by large standard deviations. Regarding ventilations, too large volumes together with flow rates as high as those performed by many of these delegates may easily lead to gastric inflation during clinical CPR.

-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- "Högteknologiska vårdmiljöer OP + IVA” är ett projekt som har genomförs av PTS Forum (Program för Teknisk Standard) bestående av 13 landsting/regioner i samarbete med Centrum för vårdens arkitektur på Chalmers. Syftet med projektet är att ta fram evidens- och erfarenhetsbaserade riktlinjer för hur framtidens hållbara högteknologiska vårdmiljöer för operation och intensivvård kan utformas. Det överordnade målet är ta fram bättre planeringsoch beslutsunderlag när vårdens lokaler planeras och byggs. Projektet ingår som en del av PTS forum strävan att utforma evidensbaserade konceptprogram för vårdlokaler. Projektet har genomförts genom litteraturstudier, studiebesök, intervjuer, föreläsningar mm. En kärnaktivitet har varit fyra workshops som har ägt rum på Chalmers med över 70 deltagare sammanlagt. Här har representanter från PTS Forum samverkat med forskare och arkitekter för att gemensamt utvärdera insamlad kunskap och utveckla idéer och förslag till lösningar. Målet med workshopparna var att diskutera hur tillgänglig kunskap från forskning och praktik kan ligga till grund för att utveckla konceptförslag till högteknologiska vårdmiljöer samtidigt som långsiktiga framtida behov och möjligheter till flexibilitet i planering och byggande är tillgodosedda. Resultaten från workshoparna har värderats och bearbetats av en projektgrupp och Chalmers. På så sätt har de ställningstaganden och illustrerade lösningar som presenteras i rapporten arbetats fram. Arbetet presenteras på några olika sätt. Denna rapport är en bruttoredovisning av allt det material som tagits fram i projektet. Den omfattar beskrivning av arbetsprocessen, framtaget teoretiskt material i ett forskningsavsnitt samt illustrationer av möjliga utformningar kompletterat med förteckning över rum och funktioner. Forskningsdelen består av sammandrag från en omfattande litteratursökning. Ett särskilt kapitel hanterar frågan om ventilation av operationslokaler. Utformningsdelen består av visualiseringar och ritningar kompletterade med förklarande texter. och omfattar utformning av operationsrum och operationsenheter/funktionsenheter, samt IVA-rum och IVA-enheter/funktionsenheter. Materialet är avsett att utgöra stöd i planeringsprocessen. Illustrerade rum och förslag till organisation av enheter ska ses som exempel att samverka kring i varje enskilt projekt snarare än som färdiga lösningar att kopiera rakt av. Materialet finns även komplett på PTS hemsida. Där är det presenterat på ett mer lättåtkomligt sätt. Utformningsdelarna kommer också att presenteras som sammanfattade och koncentrerade konceptprogram för operation och IVA var för sig. Rapporten behandlar inte de detaljerade och tekniska delar som redan täcks av PTS.

Stress Levels Escalate When Repeatedly Performing Tasks Involving Threats
- 2019
-
Ingår i: Frontiers in Psychology. - : Frontiers Media SA. - 1664-1078. ; 10, s. 1562-1562
-
Tidskriftsartikel (refereegranskat)abstract
- Police work may include performing repeated tasks under the influence of psychological stress, which can affect perceptual, cognitive and motor performance. However, it is largely unknown how repeatedly performing stressful tasks physically affect police officers in terms of heart rate and pupil diameter properties. Psychological stress is commonly assessed by monitoring the changes in these biomarkers. Heart rate and pupil diameter was measured in 12 male police officers when performing a sequence of four stressful tasks, each lasting between 20 and 130 s. The participants were first placed in a dimly illuminated anteroom before allowed to enter a brightly lit room where a scenario was played out. After each task was performed, the participants returned to the anteroom for about 30 s before performing the next sequential task. Performing a repeated sequence of stressful tasks caused a significant increase in heart rate (p = 0.005). The heart rate started to increase already before entering the scenario room and was significantly larger just after starting the task than just before starting the task (p < 0.001). This pattern was more marked during the first tasks (p < 0.001). Issuance of a verbal "abort" command which terminated the tasks led to a significant increase of heart rate (p = 0.002), especially when performing the first tasks (p = 0.002). The pupil diameter changed significantly during the repeated tasks during all phases but in a complex pattern where the pupil diameter reached a minimum during task 2 followed by an increase during tasks 3 and 4 (p ≤ 0.020). During the initial tasks, the pupil size (p = 0.014) increased significantly. The results suggest that being repeatedly exposed to stressful tasks can produce in itself an escalation of psychological stress, this even prior to being exposed to the task. However, the characteristics of both the heart rate and pupil diameter were complex, thus, the findings highlight the importance of studying the effects and dynamics of different stress-generating factors. Monitoring heart rate was found useful to screen for stress responses, and thus, to be a vehicle for indication if and when rotation of deployed personnel is necessary to avoid sustained high stress exposures.

Tidskriftsartikel (refereegranskat)abstract
- BackgroundThe Roll Back Malaria strategy recommends a combination of interventions for malaria control. Zanzibar implemented artemisinin-based combination therapy (ACT) for uncomplicated malaria in late 2003 and long-lasting insecticidal nets (LLINs) from early 2006. ACT is provided free of charge to all malaria patients, while LLINs are distributed free to children under age 5 y (“under five”) and pregnant women. We investigated temporal trends in Plasmodium falciparum prevalence and malaria-related health parameters following the implementation of these two malaria control interventions in Zanzibar.Methods and FindingsCross-sectional clinical and parasitological surveys in children under the age of 14 y were conducted in North A District in May 2003, 2005, and 2006. Survey data were analyzed in a logistic regression model and adjusted for complex sampling design and potential confounders. Records from all 13 public health facilities in North A District were analyzed for malaria-related outpatient visits and admissions. Mortality and demographic data were obtained from District Commissioner's Office. P. falciparum prevalence decreased in children under five between 2003 and 2006; using 2003 as the reference year, odds ratios (ORs) and 95% confidence intervals (CIs) were, for 2005, 0.55 (0.28–1.08), and for 2006, 0.03 (0.00–0.27); p for trend < 0.001. Between 2002 and 2005 crude under-five, infant (under age 1 y), and child (aged 1–4 y) mortality decreased by 52%, 33%, and 71%, respectively. Similarly, malaria-related admissions, blood transfusions, and malaria-attributed mortality decreased significantly by 77%, 67% and 75%, respectively, between 2002 and 2005 in children under five. Climatic conditions favorable for malaria transmission persisted throughout the observational period.ConclusionsFollowing deployment of ACT in Zanzibar 2003, malaria-associated morbidity and mortality decreased dramatically within two years. Additional distribution of LLINs in early 2006 resulted in a 10-fold reduction of malaria parasite prevalence. The results indicate that the Millennium Development Goals of reducing mortality in children under five and alleviating the burden of malaria are achievable in tropical Africa with high coverage of combined malaria control interventions.

- Purpose: To describe flow as experienced by people diagnosed with and treated for head and neck cancer. Method: A descriptive design based on a deductive qualitative content analysis was used to explain Csikszentmihalyi's flow theory from the perspective of people living with head and neck cancer. Interviews were conducted with seven participants diagnosed with and treated for different forms and stages of head and neck cancer. Results: Experiences of flow were associated with people's interests, skill levels and actions involving and creating both happiness and the feeling of something worth living for. Optimal flow was a state of consciousness in which mind and body work together, and the people were completely absorbed in an activity related to nature, hobbies or family. Microflow occurred as part of everyday life, relieving stress and anxiety and helping them to focus on their daily routines. This included humming, listening to the radio or watching TV. Conclusions: The peoples inner strength and desire to feel better made flow possible, and they used unknown skills that enhanced self-satisfaction. Managing self-care activities increased feelings of control, participation and enjoyment. This calls for person-centred care with a salutogenic approach based on the peoples own interests, skill levels and actions; what makes the person feel happy.

Tidskriftsartikel (refereegranskat)abstract
- Continuous positive airway pressure (CPAP) is the treatment of choice for obstructive sleep apnoea syndrome (OSAS), but side effects are common and long-term adherence low. The Type D (distressed) personality is defined as a combination of negative affectivity and social inhibition. The association of Type D personality with adherence has not been studied in CPAP-treated patients with OSAS. This study aimed to describe the prevalence of Type D personality in OSAS patients with CPAP treatment longer than 6 months and the association with self-reported side effects and adherence. A cross-sectional descriptive design was used. A total of 247 OSAS patients with a mean use of CPAP treatment for 55 months (6-182 months) were included. Data collection was achieved by two questionnaires; the Type D scale 14 (DS14) (Type D personality), SECI (side effects of CPAP), as well as from medical records (clinical variables and objective adherence to CPAP treatment). Type D personality occurred in 30% of the patients with OSAS and significantly (P < 0.05-0.001) increased the perceived frequency and severity of a broad range of side effects. The objective adherence was significantly lower (P < 0.001) for OSAS patients with Type D compared to OSAS patients without Type D, both with regard to a mean use of 4 h per night and 85% of the self-rated sleep time per night. The additional effect of a Type D personality on perceived side effects and adherence to CPAP treatment found in this study could be used by healthcare personnel when evaluating patients waiting for treatment.

- Title. Obstructive sleep apnoea syndrome - patients' perceptions of their sleep and its effects on their life situation Aim. This paper reports a descriptive study of how untreated patients with obstructive sleep apnoea syndrome perceived their sleep situation and how the syndrome affected their life situation. Background. Obstructive sleep apnoea syndrome is a prevalent problem independently associated with an increased risk for hypertension, cardiovascular disease, chronic heart failure and mortality. Increased consumption of healthcare resources can often be seen among patients over a long period of time since many have been undiagnosed and untreated. Methods. A phenomenographic approach was employed. Data were collected by interviews during 2005 with 20 purposively selected participants with untreated obstructive sleep apnoea syndrome. Findings. Participants described loud snoring, frequent awakenings, dyspnoea, frustration over nocturia, fear of dying during sleep and partners' anxiety about the apnoea, as being night-time effects of obstructive sleep apnoea syndrome. They described dry and sore throats, tiredness and daytime sleepiness, shame about falling asleep and snoring, thoughts about complications and depressed mood as daytime effects. Needs, such as increased alertness, improved ability to concentrate, improved relationship, adequate information as well as effective treatment, were described. Participants tried self-care strategies such as information-seeking about sleep disturbances and treatment, adapted sleeping routines, change of bedroom arrangements, adapted daily schedules, hyperactivity and avoidance of difficult situations. Conclusion. The perceived effects and needs, as well as tried self-care actions by the patients with obstructive sleep apnoea syndrome in this study, could be used to identify and evaluate concerns of other patients with obstructive sleep apnoea syndrome waiting for treatment. © 2007 The Authors.

- Objective: To compare perceptions among continuous positive airway pressure (CPAP) treated patients with obstructive sleep apnoea syndrome (OSAS) and healthcare personnel with regard to informational needs, side-effects and their consequences on adherence. Methods: A cross-sectional descriptive design was used including 350 CPAP treated OSAS patients from three Swedish hospitals and 105 healthcare personnel from 26 Swedish hospitals. Data collection was performed using two questionnaires covering informational needs, side-effects and adherence to CPAP. Results: Both groups perceived all surveyed informational areas as very important. Patients perceived the possibilities to learn as significantly greater in all areas (p < 0.001) compared to healthcare personnel, and scored significantly higher regarding positive effects on adherence of information about pathophysiology (p < 0.05), self-care (p < 0.001) and troubleshooting (p < 0.01). A total of I I out of 15 surveyed side-effects were perceived to be more frequent by healthcare personnel (p < 0.01 - p < 0.001). They also scored all side-effects to cause greater problems and decrease the CPAP use to a greater extent (p < 0.001). Conclusion: Knowledge about these differences between patients and healthcare personnel regarding educational needs, side-effects and their effects on adherence can be important when designing educational programmes to increase CPAP adherence. Practice implications: Measurement of these parameters before, during and after educational programs are suggested.

- BACKGROUND: Sexual problems are common among people with cardiovascular disease. Although clinical guidelines recommend sexual counselling for patients and their partners, there is little evidence on its effectiveness.OBJECTIVES: To evaluate the effectiveness of sexual counselling interventions (in comparison to usual care) on sexuality-related outcomes in patients with cardiovascular disease and their partners.SEARCH METHODS: We searched CENTRAL, MEDLINE, EMBASE, and three other databases up to 2 March 2015 and two trials registers up to 3 February 2016.SELECTION CRITERIA: Randomised controlled trials (RCTs) and quasi-RCTs, including individual and cluster RCTs. We included studies that compared any intervention to counsel adult cardiac patients about sexual problems with usual care.DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by Cochrane.MAIN RESULTS: We included three trials with 381 participants. We were unable to pool the data from the included studies due to the differences in interventions used; therefore we synthesised the trial findings narratively.Two trials were conducted in the USA and one was undertaken in Israel. All trials included participants who were admitted to hospital with myocardial infarction (MI), and one trial also included participants who had undergone coronary artery bypass grafting. All trials followed up participants for a minimum of three months post-intervention; the longest follow-up timepoint was five months.One trial (N = 92) tested an intensive (total five hours) psychotherapeutic sexual counselling intervention delivered by a sexual therapist. One trial (N = 115) used a 15-minute educational video plus written material on resuming sexual activity following a MI. One trial (N = 174) tested the addition of a component that focused on resumption of sexual activity following a MI within a hospital cardiac rehabilitation programme.The quality of the evidence for all outcomes was very low.None of the included studies reported any outcomes from partners.Two trials reported sexual function. One trial compared intervention and control groups on 12 separate sexual function subscales and used a repeated measures analysis of variance (ANOVA) test. They reported statistically significant differences in favour of the intervention. One trial compared intervention and control groups using a repeated measures analysis of covariance (ANCOVA), and concluded: "There were no significant differences between the two groups [for sexual function] at any of the time points".Two trials reported sexual satisfaction. In one trial, the authors compared sexual satisfaction between intervention and control and used a repeated measured ANOVA; they reported "differences were reported in favour of the intervention". One trial compared intervention and control with a repeated measures ANCOVA and reported: "There were no significant differences between the two groups [for sexual satisfaction] at any of the timepoints".All three included trials reported the number of patients returning to sexual activity following MI. One trial found some evidence of an effect of sexual counselling on reported rate of return to sexual activity (yes/no) at four months after completion of the intervention (relative risk (RR) 1.71, 95% confidence interval (CI) 1.26 to 2.32; one trial, 92 participants, very low quality of evidence). Two trials found no evidence of an effect of sexual counselling on rate of return to sexual activity at 12 week (RR 1.01, 95% CI 0.94 to 1.09; one trial, 127 participants, very low quality of evidence) and three month follow-up (RR 0.98, 95% CI 0.88 to 1.10; one trial, 115 participants, very low quality of evidence).Two trials reported psychological well-being. In one trial, no scores were reported, but the trial authors stated: "No treatment effects were observed on state anxiety as measured in three points in time". In the other trial no scores were reported but, based on results of a repeated measures ANCOVA to compare intervention and control groups, the trial authors stated: "The experimental group had significantly greater anxiety at one month post MI". They also reported: "There were no significant differences between the two groups [for anxiety] at any other time points".One trial reporting relationship satisfaction and one trial reporting quality of life found no differences between intervention and control.No trial reported on satisfaction in how sexual issues were addressed in cardiac rehabilitation services.AUTHORS' CONCLUSIONS: We found no high quality evidence to support the effectiveness of sexual counselling for sexual problems in patients with cardiovascular disease. There is a clear need for robust, methodologically rigorous, adequately powered RCTs to test the effectiveness of sexual counselling interventions for people with cardiovascular disease and their partners.

Tidskriftsartikel (refereegranskat)abstract
- Purpose: The purpose of this study was to test the reliability and validity of an existing patient classification instrument in anaesthetic nursing in a new context.Background: A patient classification system has to be used by many nurses, so consistency in how it is used is important.Methods: The study was divided into three parts. The first part was intended to measure interreliability using double assessments of 150 anaesthesia cases. In the second part, the anaesthetic nurses carried out the workload and, in part three, content validity was examined using a questionnaire and meetings.Results: The result showed good to very good consistency across the board in the nurses' assessments, which also included an overall assessment of the workload (r 0,85). The workload showed the highest mean care level for the indicator preparations/surgical position and the lowest for respiration. The questionnaire replies showed that the nurses were positive about workload, but 43.3 per cent thought that the instrument only described part of their work.Conclusion: The instrument was shown to be of use in different contexts, but the reliability and validation process should continue so as to increase reliability. Clarifying the progression between the different care levels for each indicator in the instrument can be a way of increasing its usefulness in different services. In terms of clinical work, the measurement of workload has started a valuable process of reflection on anaesthetic nursing that helps to enable the nurses to show what they do and why.

- AIM:Inhibition of diacylglycerol acyltransferase 1 (DGAT1) is a potential treatment modality for patients with type 2 diabetes mellitus and obesity, based on preclinical data suggesting it is associated with insulin sensitization and weight loss. This randomized, placebo-controlled, phase 1 study in 62 overweight men explored the effects and tolerability of AZD7687, a reversible and selective DGAT1 inhibitor.METHODS:Multiple doses of AZD7687 (1, 2.5, 5, 10 and 20 mg/day, n = 6 or n = 12 for each) or placebo (n = 20) were administered for 1 week. Postprandial serum triacylglycerol (TAG) was measured for 8 hours after a standardized 45% fat meal. Glucagon-like peptide-1 (GLP-1) and peptide YY (PYY) were measured and a paracetamol challenge was performed to assess gastric emptying.RESULTS:Dose-dependent reductions in postprandial serum TAG were demonstrated with AZD7687 doses ≥5 mg compared with placebo (p < 0.01). Significant (p < 0.001) increases in plasma GLP-1 and PYY levels were seen at these doses, but no clear effect on gastric emptying was demonstrated at end of treatment. With AZD7687doses >5 mg/day, gastrointestinal (GI) side effects increased; 11/18 of these participants discontinued treatment owing to diarrhoea.CONCLUSIONS:Altered lipid handling and hormone secretion in the gut were demonstrated during 1-week treatment with the DGAT1 inhibitor AZD7687. However, the apparent lack of therapeutic window owing to GI side effects of AZD7687, particularly diarrhoea, makes the utility of DGAT1 inhibition as a novel treatment for diabetes and obesity questionable.

Glass transition and relaxation dynamics of propylene glycol-water solutions confined in clay
- 2014
-
Ingår i: Journal of Chemical Physics. - : AIP Publishing. - 1089-7690 .- 0021-9606. ; 141:3

Tidskriftsartikel (refereegranskat)abstract
- The molecular dynamics of aqueous solutions of propylene glycol (PG) and propylene glycol methylether (PGME) confined in a two-dimensional layer-structured Na-vermiculite clay has been studied by broadband dielectric spectroscopy and differential scanning calorimetry. As typical for liquids in confined geometries the intensity of the cooperative alpha-relaxation becomes considerably more suppressed than the more local beta-like relaxation processes. In fact, at high water contents the calorimetric glass transition and related structural alpha-relaxation cannot even be observed, due to the confinement. Thus, the intensity of the viscosity related alpha-relaxation is dramatically reduced, but its time scale as well as the related glass transition temperature T-g are for both systems only weakly influenced by the confinement. In the case of the PGME-water solutions it is an important finding since in the corresponding bulk system a pronounced non-monotonic concentration dependence of the glass transition related dynamics has been observed due to the growth of hydrogen bonded relaxing entities of water bridging between PGME molecules [J. Sjostrom, J. Mattsson, R. Bergman, and J. Swenson, Phys. Chem. B 115, 10013 (2011)]. The present results suggest that the same type of structural entities are formed in the quasi-two-dimensional space between the clay platelets. It is also observed that the main water relaxation cannot be distinguished from the beta-relaxation of PG or PGME in the concentration range up to intermediate water contents. This suggests that these two processes are coupled and that the water molecules affect the time scale of the beta-relaxation. However, this is most likely true also for the corresponding bulk solutions, which exhibit similar time scales of this combined relaxation process below T-g. Finally, it is found that at higher water contents the water relaxation does not merge with, or follow, the alpha-relaxation above T-g, but instead crosses the alpha-relaxation, indicating that the two relaxation processes are independent of each other. This can only occur if the two processes do not occur in the same parts of the confined solutions. Most likely the hydration shell of the interlayer Na+ ions is causing this water relaxation, which does not participate in the alpha-relaxation at any temperature.

Experiences of healthcare and treatments in women with lipedema - results from a Swedish national survey
- 2023
-
Konferensbidrag (refereegranskat)abstract
- Objectives Lipedema is associated with multiple health problems which limit daily life. Still, the disease is frequently misunderstood in healthcare, and research from the patient’s perspective is relatively sparse. A Swedish national survey was conducted, to comprehensively examine health and quality of life among women with lipedema. Furthermore, the study explored participants’ self-care, self-reported effects of different treatments, and experiences when seeking healthcare.ResultsIn total, 245 women with lipedema responded to the survey. The majority were 40-59 years old, and over half of the participants were in lipedema stage 3. Overall, in most age groups, women with lipoedema scored approximately 25-35 points lower in their physical and mental health than an age-matched general Swedish female population. Moreover, it often took decades from disease onset, including many healthcare visits, to be correctly diagnosed. Compared to a general female population, women with lipedema scored significantly lower on satisfaction with healthcare in dimensions of availability, information and knowledge, Experiences of emotional support, continuity and coordination, respect and treatment, and participation and involvement. Particularly low scores were recorded in participants’ overall impression of healthcare, including expectations of care, perceived efficiency, being cared for, and accessing information about treatment alternatives. Women with lipedema used several different treatments to manage their health problems. Most common were performing low-intensity exercise and using compression garments, of which approximately half of the participants rated as having a good or a very good effect. Less used, but self-reported as more effective, were conservative and surgical treatments performed by healthcare professionals. ConclusionLipedema has a significant negative impact on health and quality of life. Still, the diagnosis delay is extensive, and women with lipedema generally report low levels of satisfaction with healthcare. Although managing lipedema symptoms with self-care is common, treatments performed in healthcare were identified as having the most positive effects. Unfortunately, these are less likely to be used, suggesting barriers to healthcare. Learning objectivesThis research aims to contribute to a holistic understanding of lipedema, including the management of lipedema symptoms from the patient’s perspective and the challenges these women face in healthcare. This is essential when implementing effective treatment plans and prioritising healthcare interventions.At the conclusion of this activity, participants should be able to: Recognize and describe experiences that women with lipedema have regarding their treatment and healthcareIdentify healthcare improvements for women with lipedema

Healthcare experiences, health-related stigma, and social support among Swedish women with lipoedema – results from a national survey
- 2023
-
Konferensbidrag (refereegranskat)abstract
- Lipoedema is a disease in adipose tissue associated with multiple health problems that negatively impact the quality of life. However, due to body appearance, the disease is frequently misunderstood as lifestyle-induced obesity, and the affected women are at risk of being fat-shamed and lacking prerequisite support from healthcare providers and other people. Although the negative impact lipoedema has on health and social life, research from the affected women´s perspective is relatively sparse. Therefore, we conducted a Swedish national survey to explore healthcare experiences, health-related stigma, and social support among women with lipoedema. MethodsAn online survey with closed and open questions assessing sociodemographic, lipoedema characteristics, health-care experiences, health-related stigma, and perceived social support was sent out to all Lipoedema Association groups across Sweden. ParticipantsIn total, 245 women with lipoedema responded to the survey. The majority of participants were aged 40-59, and over half were in lipoedema stage 3. Most of the women had a combination of lipoedema type 3 and type 4.ResultsThe result showed that it often takes decades, including many healthcare visits, from disease onset to diagnosis. Moreover, participants reported an overall significantly lower patient satisfaction with healthcare compared to a general Swedish female population. Especially low scores were found in the dimensions of Emotional support, Continuity and coordination, and Information and knowledge, which related to participants’ dissatisfaction with healthcare providers’ availability, responsiveness, commitment, and compassion for the patient’s worries and needs. Furthermore, compared to a general Swedish female population, women with lipoedema scored significantly more health-related social impairment. When analyzing data for stigma and health-related quality of life, significant correlations across higher levels of stigma and lower physical and social functioning and emotional well-being were found. In this study, participants generally reported a strong perception of social support, with having particularly good support from significant others (i.e., perceived support from a particular person who is not a family member or friend). Moreover, we found that the association between higher levels of social support and better emotional well-being was significant.ConclusionThe challenges associated with diagnosis delay and the low satisfaction with healthcare underscore an urgent need for healthcare improvements in the management of lipoedema. The impact health-related stigma and social support have on various aspects of functioning and well-being in women with lipoedema is crucial to acknowledge and address in healthcare to enhance the affected women's quality of life.

Women with lipoedema : a national survey on their health, health-related quality of life, and sense of coherence
- 2022
-
Ingår i: BMC Women's Health. - : BioMed Central (BMC). - 1472-6874. ; 22:1

Tidskriftsartikel (refereegranskat)abstract
- Background: Lipoedema is a chronic disease in adipose tissue that almost exclusively affects women during periods of hormonal alterations. Its main symptoms include an abnormal accumulation of subcutaneous fat in the buttock, hips, and legs, which is associated with pain, swelling, and easy bruising. Herein, a grading in three stages is used to determine disease progression. Problematically, lipoedema manifestations are often confused with lifestyle-induced obesity, which is why the various health problems among affected women often remain unrecognized. Overall, research on lipoedema is scarce. As such, this study examined the health, health-related quality of life (HRQOL), and sense of coherence (SOC) among women with lipoedema. Methods: We conducted a national cross-sectional study using an online survey assessing sociodemographic data, lipoedema characteristics, symptom severity, comorbidities, HRQOL (RAND-36), and SOC (SOC-13). In total, 245 women with lipoedema, recruited from all Lipoedema Association groups in Sweden, participated. Data were compiled with descriptive statistics, and mean differences between groups were analysed by using parametric and non-parametric tests. Results: Moderate and severe leg heaviness, pain, numbness, cold skin, feeling cold, easy bruising, and sleep problems were found to occur in all lipoedema stages. Moreover, almost all participants reported having comorbidities. Worse physical health and most substantial limitations in daily life were reported among women with the most progressive lipoedema (i.e., stage 3). Social and emotional functioning and SOC were found to be, on the other hand, primarily related to respondents’ sociodemographic data and their ages at lipoedema onset. Even though approximately 70% of the women had experienced lipoedema onset before age 30, only three (1.6%) had been diagnosed by a healthcare professional before that age. Conclusion: Having lipoedema is associated with several health problems and a lower HRQOL. In addition, the extent of delay in diagnosis within this sample indicates that many women with lipoedema are often underdiagnosed and are left without support from healthcare. These findings call for the need for greater attention on lipoedema. Moreover, further studies on how women with lipoedema manage their health and symptoms, as well as on their experiences of healthcare services and lipoedema treatments, are needed.

Attitudes towards pressure ulcer prevention : a psychometric evaluation of the Swedish version of the APuP instrument
- 2016

Tidskriftsartikel (refereegranskat)abstract
- The primary aim was to conduct a psychometric evaluation of the Attitude towards Pressure ulcer Prevention (APuP) instrument in a Swedish context. A further aim was to describe and compare attitudes towards pressure ulcer prevention between registered nurses (RNs), assistant nurses (ANs) and student nurses (SNs). In total, 415 RNs, ANs and SNs responded to the questionnaire. In addition to descriptive and comparative statistics, confirmatory factor analyses were performed. Because of a lack of support for the instrument structure, further explorative and consecutive confirmatory tests were conducted. Overall, positive attitudes towards pressure ulcer prevention were identified for all three groups, but SNs reported lower attitude scores on three items and a higher score on one item compared to RNs and ANs. The findings indicated no support in this Swedish sample for the previously reported five-factor model of APuP. Further explorative and confirmative factor analyses indicated that a four-factor model was most interpretable: (i) Priority (five items), (ii) Competence (three items), (iii) Importance (three items) and (iv) Responsibility (two items). The five-factor solution could not be confirmed. Further research is recommended to develop a valid and reliable tool to assess nurses' attitudes towards pressure ulcer prevention working across different settings on an international level.

- AIM: to replicate and establish the psychometric properties of the 74-item comprehensive Ethos Towards Wellness Questionnaire in a healthy Norwegian population in terms of content and construct validity as well as homogeneity and stability reliability.METHOD: A questionnaire with a methodological and developmental design was sent on two occasions to 214 healthy middle-aged participants and processed in two phases.RESULTS: The three life context and the ethos indexes at ordinal scale level showed an overall satisfactory construct validity (communalities > 0.30, factor loadings > 0.30, and factor total variance > 50%). On two occasions 4 weeks apart, reliability in terms of homogeneity (Cronbach's α > .70) and stability (intraclass correlation coefficient > 0.70) were also considered satisfactory for the same four indexes.CONCLUSIONS: This newly developed and possibly only questionnaire that focuses on "grasping the big human picture," based on both philosophical reasoning and empirical recommendations of wellness, was found to be valid and reliable in the screening and follow-up of wellness and ethos in a healthy Norwegian population.

- Background: Ultrasound speckle tracking offers a non-invasive way of studying strain in the free Achilles tendon where no anatomical landmarks are available for tracking. This provides new possibilities for studying injury mechanisms during sport activity and the effects of shoes, orthotic devices, and rehabilitation protocols on tendon biomechanics. Purpose: To investigate the feasibility of using a commercial ultrasound speckle tracking algorithm for assessing strain in tendon tissue. Material and Methods: A polyvinyl alcohol (PVA) phantom, three porcine tendons, and a human Achilles tendon were mounted in a materials testing machine and loaded to 4% peak strain. Ultrasound long-axis cine-loops of the samples were recorded. Speckle tracking analysis of axial strain was performed using a commercial speckle tracking software. Estimated strain was then compared to reference strain known from the materials testing machine. Two frame rates and two region of interest (ROI) sizes were evaluated. Results: Best agreement between estimated strain and reference strain was found in the PVA phantom (absolute error in peak strain: 0.21 +/- 0.08%). The absolute error in peak strain varied between 0.72 +/- 0.65% and 10.64 +/- 3.40% in the different tendon samples. Strain determined with a frame rate of 39.4Hz had lower errors than 78.6Hz as was the case with a 22mm compared to an 11mm ROI. Conclusion: Errors in peak strain estimation showed high variability between tendon samples and were large in relation to strain levels previously described in the Achilles tendon.
