    Mediators of treatment effect in minimal-contact cognitive behaviour therapy for severe health anxiety: A theory-driven analysis based on a randomised controlled trial2020Ingår i: Journal of Anxiety Disorders, ISSN 0887-6185, E-ISSN 1873-7897, Vol. 69, artikel-id 102172Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Cognitive behaviour therapy (CDT) is efficacious for severe health anxiety, but little is known about mechanisms. We analysed putative mediators of change based on 13 weekly assessments in a randomised controlled trial (N = 132) of exposure-based minimal-contact CBT (guided Internet-delivered CBT, unguided Internet-delivered CBT and bibliotherapy) vs. a waitlist control for severe health anxiety. We hypothesised that the effect of CBT on health anxiety would be mediated by non-reactivity to inner experiences, health anxiety behaviours and perceived competence. We also explored somatosensory amplification. In parallel process growth models, nonreactivity, health anxiety behaviours and perceived competence - but not somatosensory amplification - were influenced by CBT and associated with health anxiety. Random intercepts cross-lagged panel models were used to study within-individual ordering of change. None of the putative mediators systematically predicted subsequent changes in health anxiety. Rather, changes in health anxiety predicted subsequent changes in all putative mediators. In summary, CBT influenced health anxiety behaviours, non-reactivity to inner experiences and perceived competence, and these variables were associated with the outcome. However, their role as mediators was not corroborated because we found no evidence that changes in these variables predicted subsequent changes in health anxiety. We encourage further research into mediators of CBT for health anxiety.

    Ultrasound-Guided Glossopharyngeal Nerve Block A Cadaver and a Volunteer Sonoanatomy Study2017Ingår i: Regional anesthesia and pain medicine, ISSN 1098-7339, E-ISSN 1532-8651, Vol. 42, nr 2, s. 252-258Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background and Objectives: Glossopharyngeal nerve (GPN) blocks are usually performed by topical, intraoral, or peristyloid approaches, which carry significant complication risks due to the proximity of important neurovascular structures. This study presents a proof of concept for a new ultrasound (US)-guided technique, which would block the GPN distally, in the parapharyngeal space, away from the immediate vicinity of high-risk collateral structures. Methods: Five cadaver heads were dissected, and the location of theGPN was explored bilaterally. In 40 healthy volunteers (20 men and 20 women; median age, 35.5 years [range, 24-69 years]) parapharyngeal sonograms were obtained, saved, and analyzed. To assess the technical feasibility of a distal GPN block in the parapharyngeal space, unilateral US-guided dye injections were performed in 3 fresh cadavers, followed by dissections. Results: The GPN was consistently identified between the stylopharyngeal and middle pharyngeal constrictor muscles in all cadaver specimens. The median distance between the GPN and the ipsilateral greater horn of the hyoid bone was 2.4 cm (range, 2.3-2.7 cm) on the right and 2.6 cm (range, 2.3-2.9 cm) on the left. The mean skin-to pharyngealwall distances in the volunteers were 2.03 (SD, 0.41) cm on the right and 2.02 (SD, 0.45) cm on the left. The mean hyoid bone-to-pharyngeal wall distances were 2.04 (SD, 0.35) cm (right) and 2.07 (SD, 0.35) cm (left). The fresh cadaver dissections demonstrated dye deposition adjacent to theGPNin the parapharyngeal space in all specimens. Conclusions: Based on our anatomical results in cadavers and healthy volunteers, we submit that successful and safe blockade of the distal GPN at the pharyngealwall level is technically feasible under US guidance.

    Group meetings after critical illness-Giving and receiving strength2018Ingår i: Intensive & Critical Care Nursing, ISSN 0964-3397, E-ISSN 1532-4036, Vol. 46, s. 86-91Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Introduction: An increasing number of intensive care patients are surviving critical illness, but many develop mental, cognitive and physical impairments after discharge. Adapting to a new life situation, often with major challenges, implies the need of support. Therefore, it is important to develop interventions aimed at promoting recovery. Objective: The aim was to describe former intensive care patients feelings of sharing their experience of critical illness with other former patients. Method: Former intensive care patients (n = 17) participated in group meetings and wrote about their thoughts in a notebook after each group meeting. To deepen the understanding of the former patients experience 11 of the former patients were interviewed. The notes in the notebooks and the interviews were analysed using qualitative content analysis. Findings: Meeting others revealed to the former patients new dimensions of being critically ill, and they both gave and received strength from each other. The meetings were meaningful as they gained insight into other patients lives, and realised what it meant to survive intensive care. Conclusions: The group meetings meant sharing experiences and understanding the process of survival after critical illness. Giving and receiving strength from others helped the participants to go further. (C) 2017 Elsevier Ltd. All rights reserved.

    Swedish consensus reached on recording, interpretation and reporting of neonatal continuous simplified electroencephalography that is supported by amplitude-integrated trend analysis2018Ingår i: Acta Paediatrica, ISSN 0803-5253, E-ISSN 1651-2227, Vol. 107, nr 10, s. 1702-1709Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Continuous monitoring of electroencephalography (EEG), with a focus on amplitude-integrated EEG (aEEG), has been used in neonatal intensive care for decades. A number of systems have been suggested for describing and quantifying aEEG patterns. Extensive full-montage EEG monitoring is used in specialised intensive care units. The American Clinical Neurophysiology Society published recommendations for defining and reporting EEG findings in critically ill adults and infants. Swedish neonatologists and clinical neurophysiologists collaborated to optimise simplified neonatal continuous aEEG and EEG recordings based on these American documents. Conclusion: This paper describes the Swedish consensus document produced by those meetings.

    Surgical Needs at the End of the Battle of Mosul: Results from Mosul General HospitalIngår i: World Journal of Surgery, ISSN 0364-2313, E-ISSN 1432-2323Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Purpose The aim of the study was to analyze the surgical needs of patients seeking emergency care at the Mosul General Hospital in the final phase of the battle of Mosul in northern Iraq between an international military coalition and rebel forces. During the conflict, the International Red Committee of the Red Cross (ICRC) supported the hospital with staff and resources. Ceasefire in the conflict was declared at the end of July 2017. Methods Routinely collected hospital data from the ICRC-supported Mosul General Hospital from June 6, 2017, to October 1, 2017 were collected and analyzed retrospectively. All patients with weapon-related injuries as well as all patients with other types of injuries or acute surgical illness were included. Results Some 265 patients were admitted during the study period. Non-weapon-related conditions were more common than weapon-related (55.1%). The most common non-weapon-related condition was appendicitis followed by hernia and soft tissue wounds. Blast/fragment was the most frequent weapon-related injury mechanism followed by gunshot. The most commonly injured body regions were chest and abdomen. Children accounted for 35.3% of all weapon-related injuries. Patients presented at the hospital with weapon-related injuries more than 2 months after the official declaration of ceasefire. A majority of the non-weapon-related, as well as the weapon-related conditions, needed surgery (88.1% and 87.6%, respectively). Few postoperative complications were reported. Conclusions The number of children affected by the fighting seems to be higher in this cohort compared to previous reports. Even several months after the fighting officially ceased, patients with weapon-related injuries were presenting. Everyday illnesses or non-weapon-related injuries dominated. This finding underlines the importance of providing victims of conflicts with surgery for life-threatening conditions, whether weapon related or not.

    Goal-directed fluid therapy during major abdominal surgery2019Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Background: Both hypo- and hypervolemia increase the risk for postoperative complications after major abdominal surgery. Fluid needs vary amongst patients depending on differences in preoperative dehydration, intraoperative physiology and surgical characteristics. Goal-directed fluid therapy (GDFT) aims to target the right amount of fluid administration in each patient by evaluating the effect of fluid boluses on haemodynamic parameters such as stroke volume. It has been shown to reduce postoperative morbidity and is generally recommended for high-risk surgery. The overall aim of this thesis was to evaluate whether more simple devices for GDFT result in clinical benefit, thus facilitating the application of GDFT in more patients.

    Aim: To compare performance and clinical benefit of pleth variability index (PVI), a noninvasive, easy-to-use device for GDFT, with the reference method of oesophageal Doppler; to evaluate methods for measuring preoperative dehydration and its effect on fluid handling by the body; and to confirm the expected clinical benefits of GDFT in patients undergoing oesophageal resection, a high risk procedure.

    Methods: In Studies I-III 150 patients scheduled for open abdominal surgery of at least 2 hrs were randomised to GDFT with either PVI or oesophageal Doppler. In the first half of the cohort, both monitors were connected to compare intraoperative performance. In 30 patients preoperative dehydration was analysed. In study IV 64 patients undergoing oesophageal resection were randomised to GDFT using pulse contour analysis or standard treatment.

    Results: The concordance between PVI and oesophageal Doppler for indicating the need for and effect of a fluid bolus was low, and both had only limited capacity to predict the effect of a fluid bolus. Both methods resulted in comparable amounts of fluid being administered and similar clinical outcome. Preoperative dehydration was limited but did impact on fluid handling. Patients receiving GDFT during oesophageal resection received more fluid and more dobutamine compared to controls, but this did not result in any clinical benefit.

    Conclusions: There are methodological issues as well as uncertainties about the clinical benefit of GDFT. We cannot recommend a strict application of any GDFT strategy, but suggest that its components should be incorporated in a more encompassing assessment of a patient’s fluid needs. The measurement, impact and treatment of preoperative dehydration need to be further clarified.

    2016 (Engelska)Ingår i: Acta Anaesthesiologica Scandinavica, ISSN 0001-5172, E-ISSN 1399-6576, Vol. 60, nr 2, s. 183-192Artikel i tidskrift (Refereegranskat) Published
    Abstract [en]

    Background: Optimisation of stroke volume using oesophageal Doppler is an established technique to guide intraoperative fluid therapy. The method has practical limitations and therefore alternative indices of fluid responsiveness, such as ventilator-induced variation in the pulse oximetric signal (Pleth Variability Index (PVI)) could be considered. We hypothesised that both methods predict fluid responsiveness in a similar way. Methods: Seventy-five patients scheduled for open major abdominal surgery were randomised to fluid optimisation using fluid bolus algorithms based on either PVI (n = 35) or Doppler (n = 39). All patients were monitored with both methods; the non-guiding method was blind. Primary endpoint was the concordance between the methods to predict fluid responsiveness. We also analysed the ability of each method to predict a stroke volume increase >= 10% after a fluid bolus, as well as the accumulated intraoperative bolus fluid volume. Results: PVI indicated a need for fluid in one-third of the situations when Doppler did so, Cohens kappa = 0.03. A fluid bolus indicated by the PVI algorithm increased stroke volume by >= 10% in half the situations. The same was found for the Doppler algorithm. The mean total bolus volume given was 878 ml when the fluid management was governed by PVI compared to 826 ml with Doppler (P = 0.71). Conclusion: PVI-and Doppler-based stroke volume optimisations agreed poorly, which did not affect the amount of fluid administered. None of the algorithms showed a good ability to predict fluid responsiveness. Our results do not support the fluid responsiveness concept.

    Abstract [en]

    Introduction: Assessment of dehydration in the preoperative setting is of potential clinical value. The present study uses urine analysis and plasma volume kinetics, which have both been validated against induced changes in body water in volunteers, to study the incidence and severity of dehydration before open abdominal surgery begins. Methods: Thirty patients (mean age 64 years) had their urine analysed before major elective open abdominal surgery for colour, specific weight, osmolality and creatinine. The results were scored and the mean taken to represent a dehydration index. Thereafter, the patients received an infusion of 5ml/kg of Ringers acetate intravenously for over 15min. Blood was sampled for 70min and the blood haemoglobin concentration used to estimate the plasma volume kinetics. Results: Distribution of fluid occurred more slowly (Pless than0.01) and the elimination half-life was twice as long (median 40min, not significant) in the 11 patients (37%) diagnosed to be moderately dehydrated as compared with euhydrated patients. The dehydration index indicated that the fluid deficit in these patients corresponded to 2.5% of the body weight, whereas the deficit in the others was 1%. In contrast, the 11 patients who later developed postoperative nausea and vomiting had a very short elimination half-life, only 9min (median, Pless than0.01). These patients were usually euhydrated but had microalbuminuria (Pless than0.03) and higher natriuresis (Pless than0.01). Conclusions: The degree of dehydration before major surgery was modest as evidenced both by urine sampling and volume kinetic analysis.

    Abstract [en]

    Background: The impact of Goal Directed Fluid Therapy (GDFT) based on the non-invasive Pleth Variability Index (PVI) on clinical outcome after abdominal surgery has only sparingly been explored. The purpose of this study was to compare the effect of intraoperative GDFT guided by PVI to a control group using esophageal Doppler on the incidence of complications and length of hospital stay after major abdominal surgery. We hypothesized that there would be no difference between the groups. Methods: This was a randomized controlled trial in a Swedish university hospital between November 2011 and January 2015; 150 patients scheduled for open abdominal surgery lasting 2 h or more were included. Exclusion criteria included hepatic resection or severe cardiac arrhythmia. The patients were randomized 1: 1 to either the intervention group or the control group. The intervention group received intraoperative GDFT by administering fluid boluses of 3 ml/kg tetrastarch aiming at a PVI value below 10%, while GDFT in the control group aimed for optimization of stroke volume as assessed with esophageal Doppler. Blinded observers assessed complications until postoperative day 30 using pre-defined definitions, as well as length of hospital stay. Results: One hundred and-fifty patients were randomized and 146 patients were available for the final data analysis. Median duration of surgery was 3 h. A total of 64 complications occurred in the PVI group (N = 74) and 70 in the Doppler group (N = 72) (p = 0.93). Median (IQR) length of stay was 8.0 (8.0) days in the PVI group and 8.0 (9.5) in the Doppler group (P = 0.57). Conclusions: No difference in clinical outcome, as defined by number of postoperative complications, and length of hospital stay, was found when goal directed fluid therapy was applied using PVI as an alternative to esophageal Doppler. PVI appears to be an acceptable alternative to esophageal Doppler for goal directed fluid therapy during major open abdominal surgery.

    Abstract [en]

    BACKGROUND: Goal-directed therapy (GDT) is expected to be of highest benefit in high-risk surgery. Therefore, GDT is recommended during oesophageal resection, which carries a high risk of postoperative complications.

    OBJECTIVES: The aim of this study was to confirm the hypothesis that GDT during oesophageal resection improves outcome compared with standard care.

    DESIGN: A randomised controlled study.

    SETTING: Two Swedish university hospitals, between October 2011 and October 2015.

    PATIENTS: Sixty-four patients scheduled for elective transthoracic oesophageal resection were randomised. Exclusion criteria included colonic interposition and significant aortic or mitral valve insufficiency.

    INTERVENTION: A three-step GDT protocol included stroke volume optimisation using colloid boluses as assessed by pulse-contour analysis, dobutamine infusion if cardiac index was below 2.5 l min m and norepinephrine infusion if mean arterial blood pressure was below 65 mmHg.

    MAIN OUTCOME MEASURE: The incidence of complications per patient at 5 and 30 days postoperatively as assessed using a predefined list.

    RESULTS: Fifty-nine patients were available for analysis. Patients in the intervention group received more colloid fluid (2190 ± 875 vs. 1596 ± 759 ml, P < 0.01) and dobutamine more frequently (27/30 vs. 9/29, P < 0.01). The median [interquartile range, IQR] incidence of complications per patient 5 days after surgery was 2 [0 to 3] in the intervention group and 1 [0 to 2] in the control group (P = 0.10), and after 30 days 4 [2 to 6] in the intervention group and 2 [1 to 4] in the control group (P = 0.10).

    CONCLUSION: Goal-directed therapy during oesophageal resection did not result in a reduction of the incidence of postoperative complications.

    Agreement between Pleth Variability Index and oesophageal Doppler to predict fluid responsiveness2016Ingår i: Acta Anaesthesiologica Scandinavica, ISSN 0001-5172, E-ISSN 1399-6576, Vol. 60, nr 2, s. 183-192Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Optimisation of stroke volume using oesophageal Doppler is an established technique to guide intraoperative fluid therapy. The method has practical limitations and therefore alternative indices of fluid responsiveness, such as ventilator-induced variation in the pulse oximetric signal (Pleth Variability Index (PVI)) could be considered. We hypothesised that both methods predict fluid responsiveness in a similar way. Methods: Seventy-five patients scheduled for open major abdominal surgery were randomised to fluid optimisation using fluid bolus algorithms based on either PVI (n = 35) or Doppler (n = 39). All patients were monitored with both methods; the non-guiding method was blind. Primary endpoint was the concordance between the methods to predict fluid responsiveness. We also analysed the ability of each method to predict a stroke volume increase &gt;= 10% after a fluid bolus, as well as the accumulated intraoperative bolus fluid volume. Results: PVI indicated a need for fluid in one-third of the situations when Doppler did so, Cohens kappa = 0.03. A fluid bolus indicated by the PVI algorithm increased stroke volume by &gt;= 10% in half the situations. The same was found for the Doppler algorithm. The mean total bolus volume given was 878 ml when the fluid management was governed by PVI compared to 826 ml with Doppler (P = 0.71). Conclusion: PVI-and Doppler-based stroke volume optimisations agreed poorly, which did not affect the amount of fluid administered. None of the algorithms showed a good ability to predict fluid responsiveness. Our results do not support the fluid responsiveness concept.

    Pleth variability index or stroke volume optimization during open abdominal surgery: a randomized controlled trial2018Ingår i: BMC Anesthesiology, ISSN 1471-2253, E-ISSN 1471-2253, Vol. 18, artikel-id 115Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: The impact of Goal Directed Fluid Therapy (GDFT) based on the non-invasive Pleth Variability Index (PVI) on clinical outcome after abdominal surgery has only sparingly been explored. The purpose of this study was to compare the effect of intraoperative GDFT guided by PVI to a control group using esophageal Doppler on the incidence of complications and length of hospital stay after major abdominal surgery. We hypothesized that there would be no difference between the groups. Methods: This was a randomized controlled trial in a Swedish university hospital between November 2011 and January 2015; 150 patients scheduled for open abdominal surgery lasting 2 h or more were included. Exclusion criteria included hepatic resection or severe cardiac arrhythmia. The patients were randomized 1: 1 to either the intervention group or the control group. The intervention group received intraoperative GDFT by administering fluid boluses of 3 ml/kg tetrastarch aiming at a PVI value below 10%, while GDFT in the control group aimed for optimization of stroke volume as assessed with esophageal Doppler. Blinded observers assessed complications until postoperative day 30 using pre-defined definitions, as well as length of hospital stay. Results: One hundred and-fifty patients were randomized and 146 patients were available for the final data analysis. Median duration of surgery was 3 h. A total of 64 complications occurred in the PVI group (N = 74) and 70 in the Doppler group (N = 72) (p = 0.93). Median (IQR) length of stay was 8.0 (8.0) days in the PVI group and 8.0 (9.5) in the Doppler group (P = 0.57). Conclusions: No difference in clinical outcome, as defined by number of postoperative complications, and length of hospital stay, was found when goal directed fluid therapy was applied using PVI as an alternative to esophageal Doppler. PVI appears to be an acceptable alternative to esophageal Doppler for goal directed fluid therapy during major open abdominal surgery.

    Goal-directed therapy during transthoracic oesophageal resection does not improve outcome: Randomised controlled trial2019Ingår i: European Journal of Anaesthesiology, ISSN 0265-0215, E-ISSN 1365-2346, Vol. 36, nr 2, s. 153-161Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND: Goal-directed therapy (GDT) is expected to be of highest benefit in high-risk surgery. Therefore, GDT is recommended during oesophageal resection, which carries a high risk of postoperative complications.

    OBJECTIVES: The aim of this study was to confirm the hypothesis that GDT during oesophageal resection improves outcome compared with standard care.

    DESIGN: A randomised controlled study.

    SETTING: Two Swedish university hospitals, between October 2011 and October 2015.

    PATIENTS: Sixty-four patients scheduled for elective transthoracic oesophageal resection were randomised. Exclusion criteria included colonic interposition and significant aortic or mitral valve insufficiency.

    INTERVENTION: A three-step GDT protocol included stroke volume optimisation using colloid boluses as assessed by pulse-contour analysis, dobutamine infusion if cardiac index was below 2.5 l min m and norepinephrine infusion if mean arterial blood pressure was below 65 mmHg.

    MAIN OUTCOME MEASURE: The incidence of complications per patient at 5 and 30 days postoperatively as assessed using a predefined list.

    RESULTS: Fifty-nine patients were available for analysis. Patients in the intervention group received more colloid fluid (2190 ± 875 vs. 1596 ± 759 ml, P < 0.01) and dobutamine more frequently (27/30 vs. 9/29, P < 0.01). The median [interquartile range, IQR] incidence of complications per patient 5 days after surgery was 2 [0 to 3] in the intervention group and 1 [0 to 2] in the control group (P = 0.10), and after 30 days 4 [2 to 6] in the intervention group and 2 [1 to 4] in the control group (P = 0.10).

    CONCLUSION: Goal-directed therapy during oesophageal resection did not result in a reduction of the incidence of postoperative complications.

    The Effect of Microdialysis Catheter Insertion on Glutamate and Serotonin Levels in Masseter Muscle in Patients with Myofascial Temporomandibular Disorders and Healthy Controls2019Ingår i: Diagnostics (Basel), ISSN 2075-4418, Vol. 9, nr 1, artikel-id 14Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Myofascial temporomandibular disorders (TMD) are the most common cause of chronic pain in the orofacial region. Microdialysis has been used to study metabolic changes in the human masseter muscle. The insertion of the microdialysis probe causes acute tissue trauma that could affect the metabolic milieu and thereby influence the results when comparing healthy subjects to those with TMD. This study aimed to investigate the levels of serotonin and glutamate during the acute tissue trauma period in healthy subjects and in patients with TMD. Microdialysis was carried out in 15 patients with TMD and 15 controls, and samples were collected every 20 min during a period of 140 min. No significant alterations of serotonin or glutamate were observed over the 2 h period for the healthy subjects. For the TMD group, a significant decrease in serotonin was observed over time (p amp;lt; 0.001), followed by a significant increase between 120 and 140 min (p amp;lt; 0.001). For glutamate, a significant reduction was observed at 40 min compared to baseline. The results showed that there was a spontaneous increase of serotonin 2 h after the insertion of the catheter in patients with TMD. In conclusion, the results showed that there are differences in the masseter muscle levels of serotonin and glutamate during acute nociception in patients with myofascial TMD compared to healthy subjects.

    Scandcleft randomised trials of primary surgery for unilateral cleft lip and palate: 3. Descriptive study of postoperative nursing care following first stage cleft closure.2017Ingår i: Journal of Plastic Surgery and Hand Surgery, ISSN 2000-656X, E-ISSN 2000-6764, Vol. 51, nr 1, s. 6s. 21-26Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background:Cleft lip and palate is one of the most common congenital anomalies requiring surgical treatment in children, normally commenced in the first year of life. Following the initiation of a group of multicentre surgical trials of primary surgery, variations in postoperative recovery and management became apparent. An agreement was made for a nurse-led survey in eight surgical centres to document postoperative care and recovery. Materials and methods:A postoperative recovery clinical report form was developed to capture relevant data for the children participating in the four arms of the trials. This included the age and weight at admission, the postoperative recovery setting, pain management, postoperative feeding, post-operative complications, and length of hospital stay. Results:Four hundred and three nursing forms from the first surgical procedure were returned for analysis. Differences in important aspects of care such as postoperative analgesia and postoperative feeding were evident. Postoperative care was influenced by local custom and practice, as little firm clinical evidence exists to guide optimal management. Conclusion:Postoperative recovery may play a significant role in the future selection of surgical protocols, and future trials need to consider cross-study site training to familiarise nurses, prior to any changes in surgical methods.

    Scandinavian Multicenter Acute Subdural Hematoma (SMASH) Study: Study Protocol for a Multinational Population-Based Consecutive Cohort2019Ingår i: Neurosurgery, ISSN 0148-396X, E-ISSN 1524-4040, Vol. 84, nr 3, s. 799-803Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND Traumatic acute subdural hematomas (ASDHs) are associated with high rate of morbidity and mortality, especially in elderly individuals. However, recent reports indicate that the morbidity and mortality rates might have improved. OBJECTIVE To evaluate postoperative (30-d) mortality in younger vs elderly (70 yr) patients with ASDH. Comparing younger and elderly patients, the secondary objectives are morbidity patterns of care and 6 mo outcome according to Glasgow outcome scale (GOS). Finally, in patients with traumatic ASDH, we aim to provide prognostic variables. METHODS This is a large-scale population-based Scandinavian study including all neurosurgical departments in Denmark and Sweden. All adult (18 yr) patients surgically treated between 2010 and 2014 for a traumatic ASDH in Denmark and Sweden will be included. Identification at clinicaltrials.gov is NCT03284190. EXPECTED OUTCOMES We expect to provide data on potential differences between younger vs elderly patients in terms of mortality and morbidity. We hypothesize that elderly patients selected for surgery have a similar pattern of care as compared with younger patients. We will provide functional outcome in terms of GOS at 6 mo in younger vs elderly patients undergoing ASDH evacuation. Finally, clinical useful prognostic factors for favorable (GOS 4-5) vs unfavorable (GOS 1-3) will be identified. DISCUSSION An improved understanding of the clinical outcome, treatment and resource allocation, clinical course, and the prognostic factors of traumatic ASDH will allow neurosurgeons to make better treatment decisions.

    Gait training after spinal cord injury: safety, feasibility and gait function following 8 weeks of training with the exoskeletons from Ekso Bionics2018Ingår i: Spinal Cord, ISSN 1362-4393, E-ISSN 1476-5624, Vol. 56, nr 2, s. 106-116Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Study design Prospective quasi-experimental study, pre-and post-design. Objectives Assess safety, feasibility, training characteristics and changes in gait function for persons with spinal cord injury (SCI) using the robotic exoskeletons from Ekso Bionics. Setting Nine European rehabilitation centres. Methods Robotic exoskeleton gait training, three times weekly over 8 weeks. Time upright, time walking and steps in the device (training characteristics) were recorded longitudinally. Gait and neurological function were measured by 10 Metre Walk Test (10 MWT), Timed Up and Go (TUG), Berg Balance Scale (BBS), Walking Index for Spinal Cord Injury (WISCI) II and Lower Extremity Motor Score (LEMS). Results Fifty-two participants completed the training protocol. Median age: 35.8 years (IQR 27.5-52.5), men/women: N = 36/16, neurological level of injury: C1-L2 and severity: AIS A-D (American Spinal Injury Association Impairment Scale). Time since injury (TSI) amp;lt; 1 year, N = 25; amp;gt; 1 year, N = 27. No serious adverse events occurred. Three participants dropped out following ankle swelling (overuse injury). Four participants sustained a Category II pressure ulcer at contact points with the device but completed the study and skin normalized. Training characteristics increased significantly for all subgroups. The number of participants with TSI amp;lt; 1 year and gait function increased from 20 to 56% (P=0.004) and 10MWT, TUG, BBS and LEMS results improved (P amp;lt; 0.05). The number of participants with TSI amp;gt; 1 year and gait function, increased from 41 to 44% and TUG and BBS results improved (P amp;lt; 0.05). Conclusions Exoskeleton training was generally safe and feasible in a heterogeneous sample of persons with SCI. Results indicate potential benefits on gait function and balance.

    EXOSKELETON GAIT TRAINING AFTER SPINAL CORD INJURY: AN EXPLORATORY STUDY ON SECONDARY HEALTH CONDITIONS2018Ingår i: Journal of Rehabilitation Medicine, ISSN 1650-1977, E-ISSN 1651-2081, Vol. 50, nr 9, s. 806-813Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective: To explore changes in pain, spasticity, range of motion, activities of daily living, bowel and lower urinary tract function and quality of life of individuals with spinal cord injury following robotic exoskeleton gait training. Design: Prospective, observational, open-label multicentre study. Methods: Three training sessions per week for 8 weeks using an Ekso GT robotic exoskeleton (Ekso Bionics). Included were individuals with recent (amp;lt;1 year) or chronic (amp;gt;1 year) injury, paraplegia and tetraplegia, complete and incomplete injury, men and women. Results: Fifty-two participants completed the training protocol. Pain was reported by 52% of participants during the week prior to training and 17% during training, but no change occurred longitudinally. Spasticity decreased after a training session compared with before the training session (pamp;lt; 0.001), but not longitudinally. Chronically injured participants increased Spinal Cord Independence Measure (SCIM III) from 73 to 74 (p= 0.008) and improved life satisfaction (p= 0.036) over 8 weeks of training. Recently injured participants increased SCIM III from 62 to 70 (pamp;lt;0.001), but no significant change occurred in life satisfaction. Range of motion, bowel and lower urinary function did not change over time. Conclusion: Training seemed not to provoke new pain. Spasticity decreased after a single training session. SCIM III and quality of life increased longitudinally for subsets of participants.

    Internet-delivered aftercare following multimodal rehabilitation program for chronic pain: a qualitative feasibility study2018Ingår i: Journal of Pain Research, ISSN 1178-7090, E-ISSN 1178-7090, Vol. 11, s. 1715-1728Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Purpose: Methods for delivering aftercare to help chronic pain patients to continue practice self-management skills after rehabilitation are needed. Internet-delivered cognitive behavioral therapy (ICBT) has the potential to partly fill this gap given its accessibility and emphasis on self-care. Methods for engaging and motivating patients to persist throughout the full length of treatment are needed. The aim of this study was to describe how chronic pain patients work in an ICBT program, through their descriptions of what is important when they initiate behavior change in aftercare and their descriptions of what is important for ongoing practice of self-management skills in aftercare. Patients and methods: Following a multimodal rehabilitation program, 29 chronic pain patients participated in a 20-week-long Internet-delivered aftercare program (ACP) based on acceptance-based cognitive behavioral therapy. Latent content analysis was made on 138 chapters of diary-like texts written by participants in aftercare. Results: Attitudes regarding pain and body changed during ACP, as did attitudes toward self and the future for some participants. How participants practiced self-management skills was influenced by how they expressed motivation behind treatment goals. Whether they practiced acceptance strategies influenced their continuous self-management practice. Defusion techniques seemed to be helpful in the process of goal setting. Mindfulness strategies seemed to be helpful when setbacks occurred. Conclusion: Self-motivating goals are described as important both to initiate and in the ongoing practice of self-management skills. Experiencing a helpful effect of acceptance strategies seems to encourage participants to handle obstacles in new ways and to persist throughout treatment. Research on whether tailored therapist guidance might be helpful in stating self-motivating goals and contribute to ongoing practice of self-management skills is needed.

    Knowledge About Treatment, Anxiety, and Depression in Association With Internet-Based Cognitive Behavioral Therapy for Adolescents: Development and Initial Evaluation of a New Test2020Ingår i: SAGE Open, ISSN 2158-2440, E-ISSN 2158-2440, Vol. 10, nr 1, artikel-id 2158244019899095Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Evaluating knowledge and learning in psychotherapy is a growing field of research. Studies that develop and evaluate valid tests are lacking, however. Here, in the context of internet-based cognitive behavioral therapy (ICBT) for adolescents, a new test was developed using subject matter experts, consensus among researchers, self-reports by youths, and a literature review. An explorative factor analysis was performed on 93 adolescents between 15 and 19 years old, resulting in a three-factor solution with 20 items, accounting for 41% of the total variance. The factors were Act in aversive states, Using positive reinforcement, and Shifting attention. The internal consistency for the whole instrument was good (alpha = .84). Hopefully, the procedure presented here can contribute to the field by illustrating one way of evaluating knowledge in ICBT. The clinical use of the knowledge test needs further investigation.

    Non-invasive blood haemoglobin and plethysmographic variability index during brachial plexus block2015Ingår i: British Journal of Anaesthesia, ISSN 0007-0912, E-ISSN 1471-6771, Vol. 114, nr 5, s. 812-817Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background Plethysmographic measurement of haemoglobin concentration (SpHb  ), pleth variability index (PVI), and perfusion index (PI) with the Radical-7 apparatus is growing in popularity. Previous studies have indicated that SpHb  has poor precision, particularly when PI is low. We wanted to study the effects of a sympathetic block on these measurements.

    Methods Twenty patients underwent hand surgery under brachial plexus block with one Radical-7 applied to each arm. Measurements were taken up to 20 min after the block had been initiated. Venous blood samples were also drawn from the non-blocked arm.

    Results During the last 10 min of the study, SpHb  had increased by 8.6%. The PVI decreased by 54%, and PI increased by 188% in the blocked arm (median values). All these changes were statistically significant. In the non-blocked arm, these parameters did not change significantly.

    Conclusions Brachial plexus block significantly altered SpHb  , PVI, and PI, which indicates that regional nervous control of the arm greatly affects plethysmographic measurements obtained by the Radical-7. After the brachial plexus block, SpHb  increased and PVI decreased.

    Studies on Polarised Light Spectroscopy2019Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    This thesis project focuses on measurements of dermal microcirculation during vascular provocations with polarised light spectroscopy. This is done with a non-invasive method commercially available as Tissue viability imaging (TiVi) which measures concentration and oxygenation of red blood cells in the papillary dermis. Three studies were done with human subjects and one with an animal model, to validate and compare the TiVi technique with laser Doppler flowmetry, which is an established method of measuring dermal microcirculation.

    The TiVi consists of a digital camera with polarisation filters in front of the flash and lens, with software for analysis of the picture. When taking a picture with the TiVi, the polarised light that is reflected on the skin surface is absorbed by the second filter over the lens (which is perpendicular to the first filter) but a portion of light penetrates the surface of the skin and is scattered when it is reflected on tissue components. This makes the light depolarised, passes the second filter, and produces a picture for analysis. The red blood cell (RBC) has a distinct absorption pattern that differs between red and green colour compared to melanin and other components of tissue. This difference is used by the software that calculates differences in each picture element and produces a measure of output which is proportional to the concentration of red blood cells. The oxygenation of RBC can also be calculated, as there is a difference in absorption depending on oxygen state.

    The first paper takes up possible sources of error such as ambient light, and the angle and distance of the camera. The main experiment was to investigate how the local heating reaction is detected with TiVi compared to LDF.

    In the second paper arterial and venous stasis are examined in healthy subjects with TiVi.

    The Third paper is an animal study where skin flaps were raised on pigs, and the vascular pedicle is isolated to enable control of inflow and outflow of blood.The measurements were made during partial venous, total venous, and total arterial occlusion. The TiVi recorded changes in the concentration of RBC, oxygenation and heterogeneity and the results were compared with those of laser Doppler flowmetry.

    In the fourth paper oxygenation and deoxygenation of RBC: s was studied. Studies were made on the forearms of healthy subjects who were exposed to arterial and venous occlusion. Simultaneous measurements were made with TiVi and Enhanced perfusion and oxygen saturation or EPOS, which is a new device that combines laser Doppler flowmetry and diffuse reflectance spectroscopy in one probe.

    With TiVi, one can measure RBC concentration and oxygenation in the area of an entire picture or in one or multiple user defined regions of interest (ROI). Methods such as laser Doppler flowmetry makes single point measurements, which is a potential source of error both because of the heterogeneity of the microcirculation, and that the circulation be insufficient in the margins of the investigated area. TiVi has been able to measure venous stasis more accurately than laser Doppler flowmetry, and venous stasis is the more common reason for flaps to fail.

    The TiVi is an accurate way to measure the concentration of RBC and trends in oxygenation of the dermal microcirculation. It has interesting possible applications for microvascular and dermatological research, monitoring of flaps, and diagnosis of peripheral vascular disease. Future clinical studies are needed as well as development of the user interface.

    Abstract [en]

    Objective: To evaluate whether TiVi, a technique based on polarized light, could measure the change in RBC concentration during local heating in healthy volunteers. Methods: Using a custom-made transparent heater, forearm skin was heated to 42 degrees C for 40 minutes while the change in RBC concentration was measured with TiVi. The perfusion response during local heating was measured at the same time with Laser Doppler flowmetry. Results: Mean RBC concentration increased (91 +/- 34 vs. 51 +/- 34 A.U. at baseline, p less than 0.001). The spatial heterogeneity of the RBC concentration in the measured skin areas was 26 +/- 6.4% at baseline, and 23 +/- 4.6% after 40 minutes of heating. The mean RBC concentrations in two skin sites were highly correlated (0.98 at baseline and 0.96 after 40 minutes of heating). The change in RBC concentration was less than the change in perfusion, measured with LDF. Unlike with LDF, a neurally mediated peak was not observed with TiVi in most of the test subjects. Conclusions: TiVi is a valuable technique for measuring the microvascular response to local heating in the skin, and offers a high reproducibility for simultaneous measurements at different skin sites, provided carefully controlled experiments are ensured.

    Abstract [en]

    Background: : Venous occlusion in the skin is difficult to detect by existing measurement techniques. Our aim was to find out whether Tissue Viability Imaging (TiVi) was better at detecting venous occlusion by comparing it with results of laser Doppler flowmetry (LDF) during graded arterial and venous stasis in human forearm skin. Methods: : Arterial and venous occlusions were simulated in 10 healthy volunteers by inflating a blood pressure cuff around the upper right arm. Changes in the concentration of red blood cells (RBC) were measured using TiVi, while skin perfusion and concentration of moving red blood cells (CMBC) were measured using static indices of LDF during exsanguination and subsequent arterial occlusion, postocclusive reactive hyperaemia, and graded increasing and decreasing venous stasis. Results: : During arterial occlusion there was a significant reduction in the mean concentration of RBC from baseline, as well as in perfusion and CMBC (p less than 0.008). Venous occlusion resulted in a significant 28% increase in the concentration of RBC (p = 0.002), but no significant change in perfusion (mean change -14%) while CMBC decreased significantly by 24% (p = 0.02). With stepwise increasing occlusion pressures there was a significant rise in the TiVi index and reduction in perfusion (p = 0.008), while the reverse was seen when venous flow was gradually restored. Conclusion: : The concentration of RBC measured with TiVi changes rapidly and consistently during both total and partial arterial and venous occlusions, while the changes in perfusion, measured by LDF, were less consistent This suggests that TiVi could be a more useful, non-invasive clinical monitoring tool for detecting venous stasis in the skin than LDF.

    Abstract [en]

    Background: Venous congestion in skin flaps is difficult to detect. This study evaluated the ability of tissue viability imaging (TiVi) to measure changes in the concentration of red blood cells (CRBC), oxygenation, and heterogeneity during vascular provocations in a porcine fasciocutaneous flap model.

    Methods: In 5 pigs, cranial gluteal artery perforator flaps were raised (8 flaps in 5 pigs). The arterial and venous blood flow was monitored with ultrasonic flow probes. CRBC, tissue oxygenation, and heterogeneity in the skin were monitored with TiVi during baseline, 50% and 100% venous occlusion, recovery, 100% arterial occlusion and final recovery, thereby simulating venous and arterial occlusion of a free fasciocutaneous flap. A laser Doppler probe was used as a reference for microvascular perfusion in the flap.

    Results: During partial and complete venous occlusion, increases in CRBC were seen in different regions of the flap. They were more pronounced in the distal part. During complete arterial occlusion, CRBC decreased in all but the most distal parts of the flap. There were also increases in tissue oxygenation and heterogeneity during venous occlusion.

    Conclusions: TiVi measures regional changes in CRBC in the skin of the flap during arterial and venous occlusion, as well as an increase in oxygenated hemoglobin during venous occlusion that may be the result of reduced metabolism and impaired delivery of oxygen to the tissue. TiVi may provide a promising method for measuring flap viability because it is hand-held, easy to-use, and provides spatial information on venous congestion.

    Primary Chronic Osteomyelitis of the Jaws in Children: An Update on Pathophysiology, Radiological Findings, Treatment Strategies, and Prospective Analysis of Two Cases2015Ingår i: Case Reports in Dentistry, ISSN 2090-6447, E-ISSN 2090-6455, Vol. 2015, nr 152717Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective. Primary chronic osteomyelitis (PCO) of the jaws in children is associated with pain, trismus, and swelling. In children, temporomandibular joint involvement is rare and few studies have been published due to the relatively low incidence. This paper presents two cases of mandibular PCO in children with the involvement of the collum mandibulae. In addition, a review of the literature regarding demographic data, histological, radiological, and laboratory findings, and treatment strategies of PCO was also performed. Material and Methods. Prospective analyses of two PCO cases. A PubMed search was used and the articles were sorted according to their corresponding key area of focus. Results. Review of the literature revealed twenty-four cases of PCO with two cases of mandibular condyle involvement. The mean age was 18 years; the male to female ratio was 1 : 3. Most of the patients were treated with anti-inflammatory drugs in combination with decortication. Clinical recurrence was seen in 7 cases. Conclusion. A combination of anti-inflammatory drugs and surgical intervention appears to be the first choice of treatment. However, surgical removal of necrotic tissue adjacent to collum mandibulae has its limitations in children. Further investigations are of utmost importance in order to increase our knowledge and understanding of this disease.

    Like the worst toothache you've had - How people with rheumatoid arthritis describe and manage pain2017Ingår i: Scandinavian Journal of Occupational Therapy, ISSN 1103-8128, E-ISSN 1651-2014, Vol. 24, nr 6, s. 468-476Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Rheumatoid arthritis (RA) is a chronic inflammatory disease often associated with disability. Despite new treatments, pain and activity limitations are still present. Objectives: To describe how persons with RA experience and manage pain in their daily life. Methods: Seven semi-structured focus groups (FGs) were conducted and analyzed using content analysis. Results: The analysis revealed four categories: 1) Pain expresses itself in different ways referred to pain as overwhelming, aching or as a feeling of stiffness. 2) Mitigating pain referred to the use of heat, cold, medications and activities as distractions from the pain. 3) Adapting to pain referred to strategies employed as coping mechanisms for the pain, e.g. planning and adjustment of daily activities, and use of assistive devices. 4) Pain in a social context referred to the participants social environment as being both supportive and uncomprehending, the latter causing patients to hide their pain. Conclusions: Pain in RA is experienced in different ways. This emphasizes the multi-professional team to address this spectrum of experiences and to find pain management directed to the individual experience that also include the persons social environment.

    People in states worse than dead according to the EQ-5D UK value set: would they rather be dead?2018Ingår i: Quality of Life Research, ISSN 0962-9343, E-ISSN 1573-2649, Vol. 27, nr 7, s. 1827-1833Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Quality-adjusted life years (QALYs) measure health by combining length and quality of life. QALYs constitute the effect side of incremental cost-effectiveness ratios, describing the results of health economic evaluations. The objectives of this study were to (1) investigate the prevalence of states worse than dead (SWD) when using the EuroQol-5D UK value set, and (2) to study to what extent SWDs are reasonable with a starting point in experience-based valuations of health states. Data from a Swedish cross-sectional population survey were used. The survey was directed to 10,000 persons 65 years and older and its primary aim was to investigate the prevalence and consequences of chronic pain. The survey included questions reflecting life situation and well-being. Some of these were used in order to characterise people in SWD. SWD were found in 1.8% of the 6611 respondents. The prevalence of SWD increased with advancing age and was more common among women than men. The control questions used indicated that most of the persons being in SWD according to the EQ-5D UK value set most probably would not judge themselves to be in a SWD. Though negative QALY-weights are not very common, they constitute a non-negligible part of health states in a Swedish population 65 years and older. Prevalence of SWD is higher among women than men and increases with age. From responses to other questions on well-being and life situation, there is reason to doubt the reasonableness of experience-based negative QALY-weights in many cases.

    Abstract [sv]

    Kronisk smärta bland äldre är sedan länge ett välkänt problem, både i termer av samhälleliga kostnader och i termer av nedsatt livskvalitet hos drabbade individer. I syfte att uppskatta omfattningen av problemen med kronisk smärta i den äldre befolkningen insamlades data avseende såväl kostnader som livskvalitet. Ett frågeformulär sändes med post ut till ett stratifierat urval om 10 000 invånare 65 år och äldre i Linköpings och Norrköpings kommuner. Frågeformuläret innehöll frågor om demografi, levnadsvanor, livssituation samt olika frågor och instrument relaterade till personernas mående (t.ex. livskvalitet och smärtspecifika frågor). I frågeformuläret tillfrågades respondenterna om huruvida de mottog någon hjälp, informell vård, från någon närstående. Om så var fallet tillfrågades respondenten om tillstånd att kontakta dennes informella vårdgivare, samt kontaktuppgifter. Mängden informell vård tillhandahållen av närstående undersöktes med hjälp av ett frågeformulär innehållande frågor om tid som använts till informella vårdinsatser.

    Uppgifter om kostnader inhämtades från register avseende konsumtion av sjukvård, läkemedel och kommunala insatser.

    Studiens resultat visade på ett mycket tydligt samband mellan å ena sidan förekomst och grad av kronisk smärta och å andra sidan samhälleliga kostnader. Studiepopulationen delades in i tre grupper med avseende på kronisk smärta eller inte, och smärtintensitet på en 10-gradig skala under den senaste veckan (0–4 = lindrig, 5–7 = måttlig, 8–10 = svår). Med hänsyn tagen till alla kostnader (sjukvård, läkemedel, kommunal service och informell vård) konsumerade personerna med svår kronisk smärta i snitt 72% mer resurser än personerna med måttlig kronisk smärta, och 143% mer än personer med ingen eller lindrig kronisk smärta. Skillnaderna var tydligast avseende kommunala insatser och informell vård.

    Ännu mer uppseendeväckande är resultaten gällande livskvalitet för personer i de olika grupperna. Genomsnittligt indexvärde utifrån EQ-5D var för personer med ingen eller lindrig kronisk smärta 0.82. För personer med måttlig kronisk smärta var motsvarande värde 0.64, och för personer med svår kronisk smärta var värdet 0.38. EQ-VAS resulterade i mindre uttalade men tydligt signifikanta skillnader.

    Denna studie, som når en relativt stor andel av målpopulationen, visar att förekomst och intensitet av kronisk smärta bland personer 65 år och äldre påverkar samhälleliga kostnader och drabbade personers livskvalitet mycket tydligt.

    Severity of chronic pain in an elderly population in Sweden-impact on costs and quality of life2015Ingår i: Pain, ISSN 0304-3959, E-ISSN 1872-6623, Vol. 156, nr 3, s. 521-527Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Chronic pain is associated with large societal costs, but few studies have investigated the total costs of chronic pain with respect to elderly subjects. The elderly usually require informal care, care performed by municipalities, and care for chronic diseases, all factors that can result in extensive financial burdens on elderly patients, their families, and the social services provided by the state. This study aims to quantify the societal cost of chronic pain in people of age 65 years and older and to assess the impact of chronic pain on quality of life. This study collected data from 3 registers concerning health care, drugs, and municipal services and from 2 surveys. A postal questionnaire was used to collect data from a stratified sample of the population 65 years and older in southeastern Sweden. The questionnaire addressed pain intensity and quality of life variables (EQ-5D). A second postal questionnaire was used to collect data from relatives of the elderly patients suffering from chronic pain. A total of 66.5% valid responses of the 10,000 subjects was achieved; 76.9% were categorized as having no or mild chronic pain, 18.9% as having moderate chronic pain, and 4.2% as having severe chronic pain. Consumed resources increased with the severity of chronic pain. Clear differences in EQ-5D were found with respect to the severity of pain. This study found an association between resource use and severity of chronic pain in elderly subjects: the more severe the chronic pain, the more extensive (and expensive) the use of resources.

    Spectrotemporal Modulation Sensitivity as a Predictor of Speech-Reception Performance in Noise With Hearing Aids2016Ingår i: TRENDS IN HEARING, ISSN 2331-2165, Vol. 20, artikel-id 2331216516670387Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The audiogram predicts amp;lt;30% of the variance in speech-reception thresholds (SRTs) for hearing-impaired (HI) listeners fitted with individualized frequency-dependent gain. The remaining variance could reflect suprathreshold distortion in the auditory pathways or nonauditory factors such as cognitive processing. The relationship between a measure of suprathreshold auditory function-spectrotemporal modulation (STM) sensitivity-and SRTs in noise was examined for 154 HI listeners fitted with individualized frequency-specific gain. SRTs were measured for 65-dB SPL sentences presented in speech-weighted noise or four-talker babble to an individually programmed master hearing aid, with the output of an ear-simulating coupler played through insert earphones. Modulation-depth detection thresholds were measured over headphones for STM (2cycles/octave density, 4-Hz rate) applied to an 85-dB SPL, 2-kHz lowpass-filtered pink-noise carrier. SRTs were correlated with both the high-frequency (2-6 kHz) pure-tone average (HFA; R-2 = .31) and STM sensitivity (R-2 = .28). Combined with the HFA, STM sensitivity significantly improved the SRT prediction (Delta R-2 = .13; total R-2 = .44). The remaining unaccounted variance might be attributable to variability in cognitive function and other dimensions of suprathreshold distortion. STM sensitivity was most critical in predicting SRTs for listenersamp;lt;65 years old or with HFA amp;lt;53 dB HL. Results are discussed in the context of previous work suggesting that STM sensitivity for low rates and low-frequency carriers is impaired by a reduced ability to use temporal fine-structure information to detect dynamic spectra. STM detection is a fast test of suprathreshold auditory function for frequencies amp;lt;2 kHz that complements the HFA to predict variability in hearing-aid outcomes for speech perception in noise.

    Internet-Based Interventions for Adults With Hearing Loss, Tinnitus, and Vestibular Disorders: A Systematic Review and Meta-Analysis2019Ingår i: TRENDS IN HEARING, ISSN 2331-2165, Vol. 23, artikel-id 2331216519851749Artikel, forskningsöversikt (Refereegranskat)
    Abstract [en]

    Internet-based interventions have been developed to improve access to audiovestibular health care. This review aimed to identify outcomes of Internet interventions for adults with hearing loss, tinnitus, and vestibular disorders. Electronic databases and manual searches were performed to identify studies meeting eligibility for inclusion. Fifteen studies (1,811 participants) met the inclusion criteria, with nine studies targeting tinnitus distress, five considering hearing loss, and one for vestibular difficulties. Only the tinnitus and hearing loss Internet intervention studies were eligible for data synthesis. Internet-based interventions for hearing loss were diverse. Overall, they showed no significant effects, although a statistically significant moderate effect (d = 0.59) was found after removing the study with the highest risk of bias (as a result of high attrition). Most Internet-based interventions for tinnitus provided cognitive behavioural therapy. They yielded statistically significant mean effect sizes for reducing tinnitus distress compared with both inactive (d = 0.59) and active controls (d = 0.32). Significant effects were also present for the secondary outcomes of anxiety, depression, insomnia, and quality of life (combined effect d = 0.28). Only Internet-based interventions for tinnitus evaluated the 1-year postintervention effects indicated that results were maintained long term (d = 0.45). Scientific study quality was appraised using the Grading of Recommendations Assessment, Development and Evaluation approach and found to vary from very low to moderate. This review indicates the potential of Internet interventions for tinnitus to provide evidence-based accessible care. There is a need for additional high-quality evidence before conclusive results can be established regarding the effects of audiovestibular Internet interventions.

    Patients with chronic fatigue syndrome do not score higher on the autism-spectrum quotient than healthy controls: Comparison with autism spectrum disorder2018Ingår i: Scandinavian Journal of Psychology, ISSN 0036-5564, E-ISSN 1467-9450, Vol. 59, nr 4, s. 428-432Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Clinically, there is an overlap of several symptoms of chronic fatigue syndrome (CFS) and autism spectrum disorder (ASD), including fatigue; brain "fog"; cognitive impairments; increased sensitivity to sound, light, and odour; increased pain and tenderness; and impaired emotional contact. Adults with CFS (n = 59) or ASD (n = 50) and healthy controls (HC; n = 53) were assessed with the Autism-Spectrum Quotient (AQ) in a cross-sectional study. Non-parametric analysis was used to compare AQ scores among the groups. Univariate analysis of variance (ANCOVA) was used to identify if age, sex, or diagnostic group influenced the differences in scores. Patients with ASD scored significantly higher on the AQ than the CFS group and the HC group. No differences in AQ scores were found between the CFS and HC groups. AQ results were influenced by the diagnostic group but not by age or sex, according to ANCOVA. Despite clinical observations of symptom overlap between ASD and CFS, adult patients with CFS report few autistic traits in the self-report instrument, the AQ. The choice of instrument to assess autistic traits may influence the results.

    Dynamic Changes in Nociception and Pain Perception After Spinal Cord Stimulation in Chronic Neuropathic Pain Patients2015Ingår i: The Clinical Journal of Pain, ISSN 0749-8047, E-ISSN 1536-5409, Vol. 31, nr 12, s. 1046-1053Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objectives: Patients with an implanted spinal cord stimulation (SCS) system for pain management present an opportunity to study dynamic changes in the pain system in a situation where patients are not stimulated (ie, experiencing severe pain) compared with a situation in which patients have just been stimulated (ie, pain free or greatly reduced pain). The aims of this study were (1) to determine if there are differences in nociceptive withdrawal reflex thresholds (NWR-T) and electrical pain thresholds (EP-T) before and after SCS; and (2) to establish if these differences are related to psychological factors associated with chronic pain. Methods: Seventeen volunteers with chronic neuropathic pain participated in the experiment. Electrical stimuli were applied to assess the NWR-T and the EP-T. In addition, psychological factors (ie, pain characteristics, depression, anxiety, and disability indexes) were also recorded. The NWR-T and EP-T were assessed with the SCS system off (at least 8 h before the experiment), and then reassessed 1 hour after the SCS system was turned on. Results: Ongoing pain intensity ratings decreased (P=0.018), whereas the NWR-T increased (P=0.028) after the SCS was turned on, whereas no significant difference was found for EP-T (P=0.324). Psychological factors were significant predictors for EP-T but not for NWR-T. Discussion: The results of this study suggest that pain relief after SCS is partially mediated by a decrease in the excitability of dorsal horn neurons in the spinal cord.

    Benefits of resistance exercise in lean women with fibromyalgia: involvement of IGF-1 and leptin2017Ingår i: BMC Musculoskeletal Disorders, ISSN 1471-2474, E-ISSN 1471-2474, Vol. 18, artikel-id 106Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Chronic pain and fatigue improves by exercise in fibromyalgia (FM) but underlying mechanisms are not known. Obesity is increased among FM patients and associates with higher levels of pain. Symptom improvement after aerobic exercise is affected by body mass index (BMI) in FM. Metabolic factors such as insulin-like growth factor 1 (IGF1) and leptin may be involved. In this study, the aim was to evaluate the role of metabolic factors in lean, overweight and obese women during resistance exercise, in relation to symptom severity and muscle strength in women with FM. Methods: Forty-three women participated in supervised progressive resistance exercise, twice weekly for 15-weeks. Serum free and total IGF-1, IGF-binding protein 3 (IGFBP3), adiponectin, leptin and resistin were determined at baseline and after 15-weeks. Level of current pain was rated on a visual analogue scale (0-100 mm). Level of fatigue was rated by multidimensional fatigue inventory (MFI-20) subscale general fatigue (MFIGF). Knee extension force, elbow flexion force and handgrip force were assessed by dynamometers. Results: Free IGF-1 (p = 0.047), IGFBP3 (p = 0.025) and leptin (p = 0.008) were significantly decreased in lean women (n = 18), but not in the overweight (n = 17) and the obese (n = 8). Lean women with FM benefited from resistance exercise with improvements in current pain (p= 0.039, n = 18), general fatigue (MFIGF, p = 0.022, n = 18) and improved elbow-flexion force (p = 0.017, n = 18). In overweight and obese women with FM there was no significant improvement in pain or fatigue but an improvement in elbow flexion (p = 0.049; p = 0.012) after 15 weeks of resistance exercise. Conclusion: The clearest clinical response to resistance exercise was found in lean patients with FM. In these individuals, individualized resistance exercise was followed by changes in IGF-1 and leptin, reduced pain, fatigue and improved muscular strength. In overweight and obese women FM markers of metabolic signaling and clinical symptoms were unchanged, but strength was improved in the upper limb. Resistance exercise combined with dietary interventions might benefit patients with FM and overweight.

    Grey matter correlates of autistic traits in women with anorexia nervosa2018Ingår i: Journal of Psychiatry & Neuroscience, ISSN 1180-4882, E-ISSN 1488-2434, Vol. 43, nr 2, s. 79-86Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Patients with anorexia nervosa exhibit higher levels of behaviours typically associated with autism-spectrum disorder (ASD), but the neural basis is unclear. We sought to determine whether elevated autistic traits in women with anorexia nervosa may be reflected in cortical morphology. Methods: We used voxel-based morphometry (VBM) to examine regional grey matter volumes in high-resolution MRI structural brain scans in women with anorexia nervosa and matched healthy controls. The Autism-spectrum Quotient (AQ) scale was used to assess autistic traits. Results: Women with anorexia nervosa (n = 25) had higher AQ scores and lower bilateral superior temporal sulcus (STS) grey matter volumes than the control group (n = 25). The AQ scores correlated negatively with average left STS grey matter volume in women with anorexia nervosa. Limitations: We did not control for cognitive ability and examined only women with ongoing anorexia nervosa. Conclusion: Elevated autistic traits in women with anorexia nervosa are associated with morphometric alterations of brain areas linked to social cognition. This finding provides neurobiological support for the behavioural link between anorexia nervosa and ASD and emphasizes the importance of recognizing autistic traits in preventing and treating-anorexia nervosa.

    Perspectives of key stakeholders on employment of autistic adults across the united states, australia, and sweden2019Ingår i: Autism Research, ISSN 1939-3792, E-ISSN 1939-3806Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Despite efforts to improve employment outcomes for autistic individuals, internationally their employment rates remain low. There is a need to better understand the factors influencing successful employment for autistic adults in the labor market from the perspectives of multiple key stakeholders. This study represents the second in a series of papers conducted as part of an International Society for Autism Research policy brief aimed at improving employment outcomes for autistic individuals. A community consultation methodology using focus groups, forums, and interviews was applied with autistic individuals (n = 19), family members (n = 18), service providers (n = 21), employers (n = 11), researchers (n = 5), and advocacy group representatives (n = 5) in Australia, Sweden, and the United States, aiming to identify the factors perceived to determine gaining and maintaining employment for autistic individuals. Directed content analysis, guided by the International Classification of Functioning, Disability and Health (ICF), was conducted to investigate the key factors influencing employment outcomes for autistic individuals. Meaningful verbal concepts, or units of text with common themes, were also derived from the qualitative data and then linked and compared to the ICF Autism Spectrum Disorder (ASD) Core-sets. Across countries, activity and participation and environmental factor categories of the ICF were the most associated with employment outcomes. Results suggest that removal of environmental barriers and enhancing environmental facilitators may assist to remediate ASD-related difficulties in the workplace. Autism Res 2019, (c) 2019 International Society for Autism Research, Wiley Periodicals, Inc. Lay Summary This study sought to understand the perspectives of autistic individuals and key stakeholders on factors influencing if autistic adults get and keep jobs. Across Australia, Sweden, and the United States, focus groups and interviews were conducted to understand international perspectives on what helps and hinders getting and keeping a job for autistic individuals. The environment, including supports, relationships, attitudes, and services, were perceived to be the most important for workplace success. Intervention targeting barriers and facilitators in the workplace environment may support autistic adults to be successful in the labor market.

    Disembedding performance and eye gaze behavior of adolescents with Autism Spectrum Disorder2019Ingår i: Research in Autism Spectrum Disorders, ISSN 1750-9467, E-ISSN 1878-0237, Vol. 66, artikel-id UNSP 101417Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Atypical visual perception in individuals with Autism Spectrum Disorders (ASD) may contribute to superiority in disembedding tasks. Gaze behavior has provided some insights in to mechanisms underlying this purported superiority in children, however evidence is limited and requires additional investigation. Method: The performance and gaze behavior of 27 adolescents with ASD and 27 matched typically developing (TD) peers were examined during the Figure Ground Subtest of the Test of Visual Perception Skills-third edition (TVPS-3). Results: Compared to their TD counterparts, adolescents with ASD were no different in accuracy, however, had a longer response time. Differences in gaze behavior were also observed, characterized by adolescents with ASD spending less time viewing the incorrect and target figures, and spending a greater proportion of time viewing irrelevant areas of the stimuli compared to TD adolescents. Conclusions: Results suggest that while altered visual perception was observed, this did not contribute to superiority in disembedding tasks in adolescents with ASD. Future research is required to elucidate conditions under which altered visual perception may contribute to behavioral superiority.

    Investigating cognitive ability and self-reported driving performance of post-stroke adults in a driving simulator2018Ingår i: Topics in Stroke Rehabilitation, ISSN 1074-9357, E-ISSN 1945-5119, Vol. 25, nr 1, s. 44-53Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Safe driving is a complex activity that requires calibration. This means the driver can accurately assess the level of task demand required for task completion and can accurately evaluate their driving capability. There is much debate on the calibration ability of post-stroke drivers. Objectives: The aim of this study was to assess the cognition, self-rated performance, and estimation of task demand in a driving simulator with post-stroke drivers and controls. Methods: A between-groups study design was employed, which included a post-stroke driver group and a group of similarly aged older control drivers. Both groups were observed driving in two simulator-based driving scenarios and asked to complete the NASA Task Load Index (TLX) to assess their perceived task demand and self-rate their driving performance. Participants also completed a battery of psychometric tasks to assess attention and executive function, which was used to determine whether post-stroke cognitive impairment impacted on calibration. Results: There was no difference in the amount of perceived task demand required to complete the driving task. Despite impairments in cognition, the post-stroke drivers were not more likely to over-estimate their driving abilities than controls. On average, the post-stroke drivers self-rated themselves more poorly than the controls and this rating was related to cognitive ability. Conclusion: This study suggests that post-stroke drivers may be aware of their deficits and adjust their driving behavior. Furthermore, using self-performance measures alongside a driving simulator and cognitive assessments may provide complementary fitness-to-drive assessments, as well as rehabilitation tools during post-stroke recovery.

    Assessing Cognitive Ability and Simulator-Based Driving Performance in Poststroke Adults2017Ingår i: Behavioural Neurology, ISSN 0953-4180, E-ISSN 1875-8584, artikel-id 1378308Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Driving is an important activity of daily living, which is increasingly relied upon as the population ages. It has been well-established that cognitive processes decline following a stroke and these processes may influence driving performance. There is much debate on the use of off-road neurological assessments and driving simulators as tools to predict driving performance; however, the majority of research uses unlicensed poststroke drivers, making the comparability of poststroke adults to that of a control group difficult. It stands to reason that in order to determine whether simulators and cognitive assessments can accurately assess driving performance, the baseline should be set by licenced drivers. Therefore, the aim of this study was to assess differences in cognitive ability and driving simulator performance in licensed community-dwelling poststroke drivers and controls. Two groups of licensed drivers (37 poststroke and 43 controls) were assessed using several cognitive tasks and using a driving simulator. The poststroke adults exhibited poorer cognitive ability; however, there were no differences in simulator performance between groups except that the poststroke drivers demonstrated less variability in driver headway. The application of these results as a prescreening toolbox for poststroke drivers is discussed.

    Cognitive ability as a predictor of task demand and self-rated driving performance in post-stroke drivers - Implications for self-regulation2018Ingår i: Journal of Transport and Health, ISSN 2214-1405, E-ISSN 2214-1405, Vol. 9, s. 169-179Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Driving is a highly complex task requiring multiple cognitive processes that can be adversely affected post-stroke. It is unclear how much ability post-stroke adults have to self-evaluate their driving performance. Furthermore, the impact of cognitive decline on this evaluation has not been previously investigated. The aim of this study was to investigate the perceived level of task demand involved in driving tasks, and to examine differences between perceived and observed driving performance in post-stroke drivers in comparison to a control group. A further aim of the research was to investigate the influence of cognition on self-rated driving performance. A total of 78 participants (35 post-stroke and 43 controls) were assessed using a series of cognitive tasks and were observed whilst driving. Participants were asked to rate their own driving performance and the task demand involved while driving using the NASA Task Load Index. Between group analyses were conducted to determine differences in the level of self-rated performance and task demand. Further analyses were conducted to investigate whether cognition accounted for differences in task demand or self-rated performance. Overall, the results suggested that the post-stroke drivers exhibited deficits in cognition, but they did not report increased levels of task demand when driving. Post-stroke adults also rated themselves more conservatively than the controls for on-road performance, which was associated with their reduced propensity for risk. The study suggests that cognitive deficits may influence post-stroke drivers to amend their driving behaviour, in order to bring the task demand within a manageable level. Understanding the mechanisms involved in self-rated performance and estimations of task demand can help promote accurate self-regulation practices in post-stroke drivers. Furthermore, measuring calibration may assist practitioners with assessing fitness-to-drive, as well as with tailoring driving rehabilitation.

    Internet-vs. group-delivered cognitive behavior therapy for insomnia: A randomized controlled non-inferiority trial2015Ingår i: Behaviour Research and Therapy, ISSN 0005-7967, E-ISSN 1873-622X, Vol. 70, s. 47-55Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The aim of this study was to compare guided Internet-delivered to group-delivered cognitive behavioral therapy (CBT) for insomnia. We conducted an 8-week randomized controlled non-inferiority trial with 6-months follow-up. Participants were forty-eight adults with insomnia, recruited via media. Interventions were guided Internet-delivered CBT (ICBT) and group-delivered CBT (GCBT) for insomnia. Primary outcome measure was the Insomnia Severity Index (ISI), secondary outcome measures were sleep diary data, depressive symptoms, response- and remission rates. Both treatment groups showed significant improvements and large effect sizes for ISI (Within Cohens d: ICBT post = 1.8, 6-months follow-up = 2.1; GCBT post = 2.1, 6-months follow-up = 2.2). Confidence interval of the difference between groups posttreatment and at FU6 indicated non-inferiority of ICBT compared to GCBT. At post-treatment, two thirds of patients in both groups were considered responders (ISI-reduction greater than 7p). Using diagnostic criteria, 63% (ICBT) and 75% (GCBT) were in remission. Sleep diary data showed moderate to large effect sizes. We conclude that both guided Internet-CBT and group-CBT in this study were efficacious with regard to insomnia severity, sleep parameters and depressive symptoms. The results are in line with previous research, and strengthen the evidence for guided Internet-CBT for insomnia. Trial registration: The study protocol was approved by, and registered with, the regional ethics review board in Linkoping, Sweden, registration number 2010/385-31.

    Efficacy of a transdiagnostic emotion-focused exposure treatment for chronic pain patients with comorbid anxiety and depression: a randomized controlled trial2019Ingår i: Pain, ISSN 0304-3959, E-ISSN 1872-6623, Vol. 160, nr 8, s. 1708-1718Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The comorbidity between chronic pain and emotional problems has proven difficult to address with current treatment options. This study addresses the efficacy of a transdiagnostic emotion-focused exposure treatment ("hybrid") for chronic pain patients with comorbid emotional problems. Adults (n = 115) with chronic musculoskeletal pain and functional and emotional problems were included in a 2-centre, parallel randomized controlled, open-label trial comparing this treatment to an active control condition receiving a guided Internet-delivered pain management treatment based on CBT principles (iCBT). The hybrid treatment (n = 58, 10-16 sessions) integrates exposure in vivo for chronic pain based on the fear-avoidance model with an emotion-regulation approach informed by procedures in Dialectical Behavior Therapy. The iCBT (n = 57; 8 treatment modules) addresses topics such as pain education, coping strategies, relaxation, problem solving, stress, and sleep management using standard CBT techniques. Patient-reported outcomes were assessed before and after treatment as well as at a 9-month primary end point. Across conditions, 78% participants completed post-treatment and 81% follow-up assessment. Intent-to-treat analyses showed that the hybrid had a significantly better post-treatment outcome on pain catastrophizing (d = 0.39) and pain interference (d = 0.63) and significantly better follow-up outcomes on depression (d = 0.43) and pain interference (d = 0.51). There were no differences on anxiety and pain intensity. Observed proportions of clinically significant improvement favoured the hybrid on all but one comparison, but no statistically significant differences were observed. We conclude that the hybrid emotion-focused treatment may be considered an acceptable, credible, and efficacious treatment option for chronic pain patients with comorbid emotional problems.

    Long-Term Asymmetric Hearing Affects Cochlear Implantation Outcomes Differently in Adults with Pre- and Postlingual Hearing Loss2015Ingår i: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 10, nr 6, artikel-id e0129167Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In many countries, a single cochlear implant is offered as a treatment for a bilateral hearing loss. In cases where there is asymmetry in the amount of sound deprivation between the ears, there is a dilemma in choosing which ear should be implanted. In many clinics, the choice of ear has been guided by an assumption that the reorganisation of the auditory pathways caused by longer duration of deafness in one ear is associated with poorer implantation outcomes for that ear. This assumption, however, is mainly derived from studies of early childhood deafness. This study compared outcomes following implantation of the better or poorer ear in cases of long-term hearing asymmetries. Audiological records of 146 adults with bilateral hearing loss using a single hearing aid were reviewed. The unaided ear had 15 to 72 years of unaided severe to profound hearing loss before unilateral cochlear implantation. 98 received the implant in their long-term sound-deprived ear. A multiple regression analysis was conducted to assess the relative contribution of potential predictors to speech recognition performance after implantation. Duration of bilateral significant hearing loss and the presence of a prelingual hearing loss explained the majority of variance in speech recognition performance following cochlear implantation. For participants with post-lingual hearing loss, similar outcomes were obtained by implanting either ear. With prelingual hearing loss, poorer outcomes were obtained when implanting the long-term sound-deprived ear, but the duration of the sound deprivation in the implanted ear did not reliably predict outcomes. Contrary to an apparent clinical consensus, duration of sound deprivation in one ear has limited value in predicting speech recognition outcomes of cochlear implantation in that ear. Outcomes of cochlear implantation are more closely related to the period of time for which the brain is deprived of auditory stimulation from both ears.

    Gaze-based assistive technology in daily activities in children with severe physical impairments: an intervention study2017Ingår i: Developmental Neurorehabilitation, ISSN 1751-8423, E-ISSN 1751-8431, Vol. 20, nr 3, s. 129-141Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective: To establish the impact of a gaze-based assistive technology (AT) intervention on activity repertoire, autonomous use, and goal attainment in children with severe physical impairments, and to examine parents’ satisfaction with the gaze-based AT and with services related to the gaze-based AT intervention.

    Methods: Non-experimental multiple case study with before, after, and follow-up design. Ten children with severe physical impairments without speaking ability (aged 1–15 years) participated in gaze-based AT intervention for 9–10 months, during which period the gaze-based AT was implemented in daily activities.

    Results: Repertoire of computer activities increased for seven children. All children had sustained usage of gaze-based AT in daily activities at follow-up, all had attained goals, and parents’ satisfaction with the AT and with services was high.

    Discussion: The gaze-based AT intervention was effective in guiding parents and teachers to continue supporting the children to perform activities with the AT after the intervention program.

    Eye gaze performance for children with severe physical impairments using gaze-based assistive technology: a longitudinal study2016Ingår i: Assistive technology, ISSN 1040-0435, E-ISSN 1949-3614, Vol. 28, nr 2, s. 93-102Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Gaze-based assistive technology (gaze-based AT) has the potential to provide children affected by severe physical impairments with opportunities for communication and activities. This study aimed to examine changes in eye gaze performance over time (time on task and accuracy) in children with severe physical impairments, without speaking ability, using gaze-based AT. A longitudinal study with an AB design was conducted on ten children (aged 1–15 years) with severe physical impairments, who were beginners to gaze-based AT at baseline. Thereafter, all children used the gaze-based AT in daily activities over the course of the study. Compass computer software was used to measure time on task and accuracy with eye selection of targets on screen, and tests were performed with the children at baseline, after 5 months, 9–11 months, and after 15–20 months. Findings showed that the children improved in time on task after 5 months and became more accurate in selecting targets after 15–20 months. This study indicates that these children with severe physical impairments, who were unable to speak, could improve in eye gaze performance. However, the children needed time to practice on a long-term basis to acquire skills needed to develop fast and accurate eye gaze performance.

    Lived experiences of surviving in-hospital cardiac arrest2019Ingår i: Scandinavian Journal of Caring Sciences, ISSN 0283-9318, E-ISSN 1471-6712, Vol. 33, nr 1, s. 156-164Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Out-of-hospital cardiac arrest survivors suffer from psychological distress and cognitive impairments. They experience existential insecurity and vulnerability and are striving to return to a life in which well-being and the meaning of life have partly changed. However, research highlighting the experiences of in-hospital cardiac arrest survivors is lacking. This means that evidence for postresuscitation care has largely been extrapolated from studies on out-of-hospital cardiac arrest survivors, without considering potential group differences. Studies investigating survivors experiences of an in-hospital cardiac arrest are therefore needed.

    Communication between patients with obstructive sleep apnoea syndrome and healthcare personnel during the initial visit to a continuous positive airway pressure clinic2017Ingår i: Journal of Clinical Nursing, ISSN 0962-1067, E-ISSN 1365-2702, Vol. 26, nr 3-4, s. 568-577Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Aims and objectives. To describe facilitators and barriers from a patient perspective in communications between patients with obstructive sleep apnoea syndrome and healthcare personnel during the first meeting when continuous positive airway pressure is initiated. Background. Adherence to continuous positive airway pressure treatment tends to be poor, especially at the initial phase of treatment. Communication between the patient and healthcare personnel has not been studied from the patient perspective, as either a barrier or facilitator for adherence. Methods. A descriptive design using qualitative content analysis was used. Interviews with 25 patients with obstructive sleep apnoea syndrome took place after their initial visit at four continuous positive airway pressure clinics. A deductive analysis based on The 4 Habits Model (i.e. emphasise the importance of investing in the beginning of the consultation, elicit the patients perspective, demonstrate empathy and invest in the end of the consultation) was conducted. Results. Building confidence (i.e. structure building, information transfer, commitment) or hindering confidence (i.e. organisational insufficiency, stress behaviour, interaction deficit) was associated with investing in the beginning. Motivating (i.e. situational insight, knowledge transfer, practical training) or demotivating (i.e. expectations, dominance and power asymmetry, barriers) was associated with eliciting the patients perspective. Building hope (i.e. awareness, sensitivity, demonstration of understanding) or hindering hope (i.e. unprepared, uncommitted, incomprehension) was associated with showing empathy. Agreement (i.e. confirmation, responsibilities, comprehensive information) or disagreement (i.e. structural obscurity, irresponsibility, absent-mindedness) was associated with investing in the end. Conclusions. Understanding of facilitators and barriers, as described by patients, can be used to improve contextual conditions and communication skills among healthcare personnel. Relevance to clinical practice. A patient-centred communication technique should be used in relation to all stages of The 4 Habits Model to facilitate shared decision-making and improve adherence to continuous positive airway pressure treatment.

    Psychometric properties of the Ethos Brief Index (EBI) using factorial structure and Rasch Analysis among patients with obstructive sleep apnea before and after CPAP treatment is initiated.2019Ingår i: Sleep and Breathing, ISSN 1520-9512, E-ISSN 1522-1709, Vol. 23, nr 3, s. 761-768Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND: Continuous positive airway treatment (CPAP) is the recommended treatment for patients with obstructive sleep apnea (OSA). Outcome measures often focus on clinical and/or self-rated variables related to the medical condition. However, a brief validated instrument focusing on the whole life situation (i.e., ethos) suitable for clinical practice is missing. The aim of this study was to investigate factorial structure, categorical functioning of the response scale, and differential item functioning across sub-populations of the Ethos Brief Index (EBI) among patients with obstructive sleep apnea (OSA) before and after initiation of continuous positive airway pressure (CPAP).

    METHODS: A prospective design, including 193 patients with OSA (68% men, 59.66 years, SD 11.51) from two CPAP clinics, was used. Clinical assessment and overnight respiratory polygraphy were used to diagnose patients. Questionnaires administered before and after 6 months of CPAP treatment included EBI, Epworth Sleepiness Scale (ESS), Hospital Anxiety and Depression Scale, and global perceived health (initial item in SF-36). The validity and reliability of the EBI were investigated using Rasch and confirmatory factor analysis models. Measurement invariance, unidimensionality, and differential item functioning across gender groups, Apnea-Hypopnea Index, and ESS groups were assessed.

    RESULTS: The reliability of the EBI was confirmed using composite reliability and Cronbach's alpha. The results supported unidimensionality of the EBI in confirmatory factor analysis and the Rasch model. No differential item functioning was found. A latent profile analysis yielded two profiles of patients with low (n = 42) and high (n = 151) ethos. Patients in the low ethos group were younger and had higher depression scores, lower perceived health, and higher body mass index.

    CONCLUSIONS: The EBI is a valid tool with robust psychometric properties suitable for use among patients with OSA before and after treatment with CPAP is initiated. Future studies should focus on its predictive validity.

    Promoting CPAP adherence in clinical practice: A survey of Swedish and Norwegian CPAP practitioners beliefs and practices2018Ingår i: Journal of Sleep Research, ISSN 0962-1105, E-ISSN 1365-2869, Vol. 27, nr 6, artikel-id UNSP e12675Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The benefits of continuous positive airway pressure (CPAP) treatment for obstructive sleep apnea are well established, but adherence tends to be low. Research exploring CPAP practitioners beliefs around determinants of CPAP adherence, and the actions they use in clinical practice to promote CPAP adherence is lacking. This study aimed to: (i) develop and validate a questionnaire to assess beliefs and current practices among CPAP practitioners; (ii) explore practitioners beliefs regarding the main determinants of patient adherence, and the actions practitioners most commonly use to promote CPAP adherence; and (iii) explore the associations between perceived determinants and adherence-promotion actions. One-hundred and forty-two CPAP practitioners in Sweden and Norway, representing 93% of all Swedish and 62% of all Norwegian CPAP centres, were surveyed via a questionnaire exploring potential determinants (18 items) and adherence-promotion actions (20 items). Confirmatory factor analysis and second-order structural equational modelling were used to identify patterns of beliefs, and potential associations with adherence-promotion actions. Patients knowledge, motivation and attitudes were perceived by practitioners to be the main determinants of CPAP adherence, and educating patients about effects, management and treatment adjustments were the most common practices. Knowledge was shown to predict educational and informational actions (e.g. education about obstructive sleep apnea and CPAP). Educational and informational actions were associated with medical actions (e.g. treatment adjustment), but knowledge, attitude and support had no association with medical actions. These findings indicate that a wide variety of determinants and actions are considered important, though the only relationship observed between beliefs and actions was found for knowledge and educational and informational actions.
