1.	Israelsson, Johan, et al. (author) Health status and psychological distress among in-hospital cardiac arrest survivors in relation to gender 2017 In: Resuscitation. - : Elsevier. - 0300-9572 .- 1873-1570. ; 114, s. 27-33 Journal article (peer-reviewed)abstract AIM: To describe health status and psychological distress among in-hospital cardiac arrest (IHCA) survivors in relation to gender.METHODS: This national register study consists of data from follow-up registration of IHCA survivors 3-6 months post cardiac arrest (CA) in Sweden. A questionnaire was sent to the survivors, including measurements of health status (EQ-5D-5L) and psychological distress (HADS).RESULTS: Between 2013 and 2015, 594 IHCA survivors were included in the study. The median values for EQ-5D-5L index and EQ VAS among survivors were 0.78 (q1-q3=0.67-0.86) and 70 (q1-q3=50-80) respectively. The values were significantly lower (p<0.001) in women compared to men. In addition, women reported more problems than men in all dimensions of EQ-5D-5L, except self-care. A majority of the respondents reported no problems with anxiety (85.4%) and/or symptoms of depression (87.0%). Women reported significantly more problems with anxiety (p<0.001) and symptoms of depression (p<0.001) compared to men. Gender was significantly associated with poorer health status and more psychological distress. No interaction effects for gender and age were found.CONCLUSIONS: Although the majority of survivors reported acceptable health status and no psychological distress, a substantial proportion reported severe problems. Women reported worse health status and more psychological distress compared to men. Therefore, a higher proportion of women may be in need of support. Health care professionals should make efforts to identify health problems among survivors and offer individualised support when needed.

I denna rapport ges en översikt över pågående och planerade ansatser baserade påartificiell intelligens (AI) inom akutsjukvård med särskild tonvikt på omhändertagandet av traumapatienter, där lösningarna skulle kunna bidra till att Försvarsmakten kan bibehålla sin sjukvårdskapacitet i kritiska lägen. Rapporten är ett resultat av samarbetet mellan FM, FOI, FMV, FHS och KI, och vänder sig i första hand till Försvarsmaktens strategiska ledning.Användningen av AI-teknik i framtida beslutsstöd kan skapa nya möjligheter till avlastning av personal och resurseffektivisering. Tekniken ger möjligheter att i realtid samla in, bearbeta och analysera stora mängder blandadinformation om förbands hälsoläge och fysiska stridsvärde. Bedömning av skadade kan t.ex. göras av triagedrönare och den efterföljande evakueringen kanunderlättas av intelligenta autonoma plattformar. Införandet av AI-system ställer dock vårdgivaren inför svåra etiska och medikolegala överväganden.Försvarsmedicin har en central roll i Försvarsmaktens krigföringsförmåga och för samhällets uthållighet. För att nyttja hela AI-teknikens framfart till Försvarsmaktens nytta måste dess innebörd och konsekvens för försvarsmedicinen förstås.

3.	Liu, Yuanhua, 1971, et al. (author) Considering the importance of user profiles in interface design 2009 In: User Interfaces. ; , s. 23- Book chapter (other academic/artistic)abstract User profile is a popular term widely employed during product design processes by industrial companies. Such a profile is normally intended to represent real users of a product. The ultimate purpose of a user profile is actually to help designers to recognize or learn about the real user by presenting them with a description of a real user’s attributes, for instance; the user’s gender, age, educational level, attitude, technical needs and skill level. The aim of this chapter is to provide information on the current knowledge and research about user profile issues, as well as to emphasize the importance of considering these issues in interface design. In this chapter, we mainly focus on how users’ difference in expertise affects their performance or activity in various interaction contexts. Considering the complex interaction situations in practice, novice and expert users’ interactions with medical user interfaces of different technical complexity will be analyzed as examples: one focuses on novice and expert users’ difference when interacting with simple medical interfaces, and the other focuses on differences when interacting with complex medical interfaces. Four issues will be analyzed and discussed: (1) how novice and expert users differ in terms of performance during the interaction; (2) how novice and expert users differ in the perspective of cognitive mental models during the interaction; (3) how novice and expert users should be defined in practice; and (4) what are the main differences between novice and expert users’ implications for interface design. Besides describing the effect of users’ expertise difference during the interface design process, we will also pinpoint some potential problems for the research on interface design, as well as some future challenges that academic researchers and industrial engineers should face in practice.

(author) Nurses' conceptions of decision making concerning life-sustaining treatment 2008 In: Nursing Ethics. - London : Edward Arnold. - 0969-7330 .- 1477-0989. ; 15:2, s. 160-173 Journal article (peer-reviewed)abstract The aim of this study was to describe nurses' conceptions of decision making with regard to life-sustaining treatment for dialysis patients. Semistructured interviews were conducted with 13 nurses caring for such patients at three hospitals. The interview material was subjected to qualitative content analysis. The nurses saw decision making as being characterized by uncertainty and by lack of communication and collaboration among all concerned. They described different ways of handling decision making, as well as insufficiency of physician-nurse collaboration, lack of confidence in physicians, hindrances to patient participation, and ambivalence about the role of patients' next of kin. Future research should test models for facilitating communication and decision making so that decisions will emerge from collaboration of all concerned. Nurses' role in decision making also needs to be discussed.

(author) Mild Hypercapnia or Normocapnia after Out-of-Hospital Cardiac Arrest 2023 In: New England Journal of Medicine. - 0028-4793. ; 389:1, s. 45-57 Journal article (peer-reviewed)abstract Abstract Background Guidelines recommend normocapnia for adults with coma who are resuscitated after out-of-hospital cardiac arrest. However, mild hypercapnia increases cerebral blood flow and may improve neurologic outcomes. Methods We randomly assigned adults with coma who had been resuscitated after out-of-hospital cardiac arrest of presumed cardiac or unknown cause and admitted to the intensive care unit (ICU) in a 1:1 ratio to either 24 hours of mild hypercapnia (target partial pressure of arterial carbon dioxide [Paco2], 50 to 55 mm Hg) or normocapnia (target Paco2, 35 to 45 mm Hg). The primary outcome was a favorable neurologic outcome, defined as a score of 5 (indicating lower moderate disability) or higher, as assessed with the use of the Glasgow Outcome Scale-Extended (range, 1 [death] to 8, with higher scores indicating better neurologic outcome) at 6 months. Secondary outcomes included death within 6 months. Results A total of 1700 patients from 63 ICUs in 17 countries were recruited, with 847 patients assigned to targeted mild hypercapnia and 853 to targeted normocapnia. A favorable neurologic outcome at 6 months occurred in 332 of 764 patients (43.5%) in the mild hypercapnia group and in 350 of 784 (44.6%) in the normocapnia group (relative risk, 0.98; 95% confidence interval [CI], 0.87 to 1.11; P=0.76). Death within 6 months after randomization occurred in 393 of 816 patients (48.2%) in the mild hypercapnia group and in 382 of 832 (45.9%) in the normocapnia group (relative risk, 1.05; 95% CI, 0.94 to 1.16). The incidence of adverse events did not differ significantly between groups. Conclusions In patients with coma who were resuscitated after out-of-hospital cardiac arrest, targeted mild hypercapnia did not lead to better neurologic outcomes at 6 months than targeted normocapnia.

6.	Löf, Lennart, et al. (author) Severely ill ICU patients recall of factual events and unreal experiences of hospital admission and ICU stay : 3 and 12 months after discharge. 2006 In: Intensive & Critical Care Nursing. - : Elsevier BV. - 0964-3397 .- 1532-4036. ; 22:3, s. 154-166 Journal article (peer-reviewed)abstract There is a lack of knowledge regarding how critically ill patients recall of the ICU and their life-threatening condition changes over time. The purpose of this study is to describe critically ill and ventilator-treated patients' recollections of both factual events and unreal experiences at 3 and 12 months following discharge from the ICU. The study is qualitative and encompasses nine critically ill ICU patients, ventilator-treated for more than 72 h. The participants were interviewed twice, at 3 and 12 months after their discharge from the ICU. The interviews were analysed using qualitative content analysis. The patients in this study reported unreal experiences, memory confusion and/or disturbances before admittance to the ICU and before their respirator treatment. Their "unreal experiences" were far clearer than their memories of factual occurrences. Patients' fragmentary memories of factual events and their recall of unreal experiences were practically unchanged after 12 month. Their unreal experiences could still be recalled and related after 12 months, but not with the same expression and feeling as earlier (3 months). The unreal experiences were not - after 12 months - their initial recollections, as they had been after 3 months. Conclusions: Patients' recollections of both factual events and unreal experiences show very little variation between 3 and 12 months. The stability of long-term memory after 12 months shows that the recollection of their experiences had been both traumatic and emotionally charged. This study shows that critically ill patients were affected by cognitive disturbances and/or disturbed memory before their arrival at the ICU. This result indicates the need of ICU follow-up clinics.
7.	Khoshnood, Ardavan (author) Prehospital Diagnosis and Oxygen Treatment in ST Elevation Myocardial Infarction 2017 Doctoral thesis (other academic/artistic)abstract IntroductionPaper I: An Artificial Neural Network (ANN) was constructed to identify ST Elevation Myocardial Infarction (STEMI) and predict the need for Percutaneous Coronary Intervention (PCI). Paper II, III and IV: Studies suggest that O2 therapy may be harmful in STEMI patients. We therefore conducted the SOCCER study to evaluate the effects of O2 therapy in STEMI patients.MethodsPaper I: 560 ambulance ECGs sent to the Cardiac Care Unit (CCU), was together with the CCU physicians interpretation and decision of conducting an acute PCI or not collected, and compared with the interpretation and PCI decision of the ANN. Paper II, III, IV: Normoxic (≥94%) STEMI patients accepted for acute PCI were in the ambulance randomized to standard care with 10 L/min O2 or room air. A subset of the patients underwent echocardiography for determination of the Left Ventricular Ejection Fraction (LVEF) and the Wall Motion Score Index (WMSI). All patients had a Cardiac Magnetic Resonance Imaging (CMRI) to evaluate Myocardial area at Risk (MaR), Infarct Size (IS) and Myocardial Salvage Index (MSI).ResultsPaper I: The area under the ANN’s receiver operating characteristics curve for STEMI detection as well as predicting the need of acute PCI were very good.Paper II, III, IV: No significant differences could be shown in discussing MaR, MSI or IS between the O2 group (n=46) and the air group (n=49). Neither could any differences be shown for LVEF and WMSI at the index visit as well after six months between the O2 group (n=46) and the air group (n=41)ConclusionsPaper I: The results indicate that the number of ECGs sent to the CCU could be reduced with 2/3 as the ANN would safely identify ECGs not being STEMI.Paper II, III, IV: The results suggest that it is safe to withhold O2 therapy in normoxic, stable STEMI patients.
8.	Lind, Susanne, et al. (author) Implementation of national palliative care guidelines in Swedish acute care hospitals: A qualitative content analysis of stakeholders’ perceptions 2017 In: Health Policy. - : Elsevier BV. - 0168-8510 .- 1872-6054. ; 121:11, s. 1194-1201 Journal article (peer-reviewed)abstract In high-income countries a large proportion of all deaths occur in hospitals. A common way to translate knowledge into clinical practice is developing guidelines for different levels of health care organisations. During 2012, national clinical guidelines for palliative care were published in Sweden. Later, guidance for palliative care was issued by the National Board of Health and Welfare. The aim of this study was two-fold: to investigate perceptions regarding these guidelines and identify obstacles and opportunities for implementation of them in acute care hospitals. Interviews were conducted with local politicians, chief medical officers and health professionals at acute care hospitals. The Consolidated Framework for Implementation Research was used in a directed content analysis approach. The results showed little knowledge of the two documents at all levels of the health care organisation. Palliative care was primarily described as end of life care and only few of the participants talked about the opportunity to integrate palliative care early in a disease trajectory. The environment and culture at hospitals, characterised by quick decisions and actions, were perceived as obstacles to implementation. Health professionals' expressed need for palliative care training is an opportunity for implementation of clinical guidelines. There is a need for further implementation of palliative care in hospitals. One option for further research is to evaluate implementation strategies tailored to acute care. © 2017 Elsevier B.V.
9.	Hommel, Ami, et al. (author) Influence of optimised treatment of people with hip fracture on time to operation, length of hospital stay, reoperations and mortality within 1 year 2008 In: Injury. - : Elsevier. - 0020-1383 .- 1879-0267. ; 39:10, s. 1164-1174 Journal article (peer-reviewed)abstract Hip fractures are a major cause of hospital stay among the elderly, and result in increased disability and mortality. In this study from 1 April 2003 to 31 March 2004, the influence of optimised treatment of hip fracture on time to operation, length of hospital stay, reoperations and mortality within 1 year were investigated. Comparisons were made between the first 210 patients in the period and the last 210 patients, who followed the new clinical pathway introduced at the University Hospital in Lund, Sweden. Early surgery, within 24h, was not associated with reduced mortality, but was significantly associated with reduced length of stay (p<0.001). Significantly more cases of osteosynthesis for femoral neck fracture were reoperated compared with all other types of surgery (p<0.001) when reoperations with extraction of the hook pins in healed fractures were excluded. Mortality was significantly higher among men than women at 4 (p=0.025) and 12 (p=0.001) months after fracture and among medically fit patients with administrative delay to surgery compared with patients with no delay (p<0.001).

(author) Antibiotic use during coronavirus disease 2019 intensive care unit shape multidrug resistance bacteriuria : A Swedish longitudinal prospective study 2023 In: Frontiers in Medicine. - : Frontiers Media S.A.. - 2296-858X. ; 10 Journal article (peer-reviewed)abstract Objectives: High frequency of antimicrobial prescription and the nature of prolonged illness in COVID-19 increases risk for complicated bacteriuria and antibiotic resistance. We investigated risk factors for bacteriuria in the ICU and the correlation between antibiotic treatment and persistent bacteria.Methods: We conducted a prospective longitudinal study with urine from indwelling catheters of 101 ICU patients from Uppsala University Hospital, Sweden. Samples were screened and isolates confirmed with MALDI-TOF and whole genome sequencing. Isolates were analyzed for AMR using broth microdilution. Clinical data were assessed for correlation with bacteriuria.Results: Length of stay linearly correlated with bacteriuria (R2 = 0.99, p ≤ 0.0001). 90% of patients received antibiotics, primarily the beta-lactams (76%) cefotaxime, piperacillin-tazobactam, and meropenem. We found high prevalence of Enterococcus (42%) being associated with increased cefotaxime prescription. Antibiotic-susceptible E. coli were found to cause bacteriuria despite concurrent antibiotic treatment when found in co-culture with Enterococcus.Conclusion: Longer stays in ICUs increase the risk for bacteriuria in a predictable manner. Likely, high use of cefotaxime drives Enterococcus prevalence, which in turn permit co-colonizing Gram-negative bacteria. Our results suggest biofilms in urinary catheters as a reservoir of pathogenic bacteria with the potential to develop and disseminate AMR.
11.	Krakau, Karolina, 1968- (author) Energy Balance out of Balance after Severe Traumatic Brain Injury 2010 Doctoral thesis (other academic/artistic)abstract The overall aim of the research presented here was to expand the knowledge on metabolic course and nutritional outcome in patients with severe traumatic brain injury and to analyze the use and accuracy of different methods of assessment. Study I, a systematic review of 30 articles demonstrated consistent data on increased metabolic rate, of catabolism and of upper gastrointestinal intolerance in the majority of the patients during early post injury period. Data also indicated a tendency of less morbidity and mortality in early fed patients. Study II, a retrospective survey, based on medical records of 64 patients from three regions in Sweden, showed that the majority of patients regained their independence in eating within six months post injury. However, energy intake was set at a low level and 68 % of the patients developed malnutrition with 10 to 29 % loss of initial body mass during the first and second month post injury. Study III, a questionnaire based study addressed to 74 care units caring for patients with severe traumatic brain injury showed that resources in terms of qualified staff members were reportedly good, but nutritional guidelines were adopted in less than half of the units, screening for malnutrition at admission was rarely performed and surveillance of energy intake declined when oral intake began. Moreover, assessment of energy requirements relied on calculations and the profession in charge to estimate energy requirement varied depending on nutritional route and unit speciality. At transferral between units nutritional information was lost. Study IV and V, a prospective descriptive study on metabolic course, energy balance and methods of assessment in six patients showed that patients were in negative energy balance from 3rd week post injury and lost 8-19 % of their initial body weight. Concurrent nutritional problems were difficulties in retaining enteral and/or parenteral nutrition delivery routes until oral feeding was considered satisfactory. The majority of methods for predicting energy expenditure agreed poorly with measured energy expenditure. The Penn-State equation from 1998 was the only valid predictive method during mechanical ventilation. This thesis concludes that patients with moderate or severe traumatic brain injury exhibit a wide range of increased metabolic rate, catabolism and upper gastrointestinal intolerance during the early post-injury period. Most patients regain independence in eating, but develop malnutrition. Suggested explanations, other than the systemic disturbances early post injury, could be the use of inaccurate predictions of energy expenditure, deficient nutritional routines and difficulties in securing alternative nutritional routes until oral feeding is satisfactory. The impact of timing, content and ways of administration of nutritional support on neurological outcome after a severe traumatic brain injury remains to be demonstrated.
12.	Haukenes, I., et al. (author) Does pain severity guide selection to multimodal pain rehabilitation across gender? 2015 In: European Journal of Pain. - : Wiley. - 1090-3801 .- 1532-2149. ; 19:6, s. 826-833 Journal article (peer-reviewed)abstract BackgroundStudies have addressed the effect of multimodal pain rehabilitation (MMR), whereas criteria for selection are sparse. This study examines whether higher scores on musculoskeletal pain measures are associated with selection to MMR, and whether this differs across gender. MethodA clinical population of 262 male and 589 female patients was recruited consecutively during 3 years, 2007-2010. The patients were referred from primary care to a pain rehabilitation clinic in Northern Sweden for assessment and selection to MMR. Register-based data on self-reported pain were linked to patients' records where outcome (MMR or not) was stated. We modelled odds ratios for selection to MMR by higher scores on validated pain measures (pain severity, interference with daily life, pain sites and localized pain vs. varying pain location). Covariates were age, educational level and multiple pain measures. Anxiety and depression (Hospital, Anxiety and Depression Scale) and working status were used in sensitivity tests. ResultsHigher scores of self-reported pain were not associated with selection to MMR in multivariate models. Among women, higher scores on pain severity, pain sites and varying pain location (localized pain=reference) were negatively associated with selection to MMR. After adjustment for multiple pain measures, the negative odds ratio for varying location persisted (OR=0.59, 95% CI=0.39-0.89). ConclusionHigher scores on self-reported pain did not guide selection to MMR and a negative trend was found among women. Studies of referral patterns and decision processes may contribute to a better understanding of the clinical practice that decides selection to MMR.
13.	Lind, Anne-Li, et al. (author) Affinity Proteomics Applied to Patient CSF Identifies Protein Profiles Associated with Neuropathic Pain and Fibromyalgia Other publication (other academic/artistic)abstract Objective: Today, there are no biological tests on which to base pain diagnoses, treatment choices or to understand the biological processes underlying and accompanying chronic pain for the individual pain patient. Relevant biological markers would greatly aid in diagnosis and treatment of patients with chronic pain. Our study aimed to find proteins in CSF associated with fibromyalgia and neuropathic pain, two common and poorly understood chronic pain conditions.Methods: We have performed CSF protein profiling of 55 proteins using a 100-plex antibody suspension bead array. We collected, analyzed and compared CSF samples from 25 patients with neuropathic pain (two independent sets, n=14 patients for discovery and n=11 for verification), 40 patients with fibromyalgia and 135 controls without neurological disease from two different populations.Results: We found significant differences in CSF protein levels between patients and controls (p<0.05). Among these proteins, Apolipoprotein C1 (APOC1) was found to be increased in CSF of neuropathic pain patients compared to controls and there was a non-significant trend for increased levels also in fibromyalgia patient CSF. Ectonucleotide pyrophosphatase (ENPP2, Autotaxin) was increased in the CSF of fibromyalgia patients compared to all other groups including neuropathic pain patients. Multivariate analysis revealed partially overlapping and partially distinct CSF profiles in neuropathic pain patients compared with fibromyalgia and controls for several other proteins including angiotensinogen (AGT), prostaglandin-H2 D-isomerase (PTGDS), neurexin-1 (NRXN1), superoxide dismutase 1 (SOD1) and superoxide dismutase 3 (SOD3).Conclusions: Our results, suggest that the CSF protein profiles of neuropathic pain and fibromyalgia patients may be different from each other and from those of controls. CSF levels of APOC1, ENPP2, AGT, PTGDS, NRXN1, SOD1 and SOD3 should be further investigated for their potential to serve as biomarkers of different kinds of pain pathophysiology.
14.	Bjurling-Sjöberg, Petronella, 1968-, et al. (author) Struggling for a feasible tool - the process of implementing a clinical pathway in intensive care: a grounded theory study 2018 In: BMC Health Serv Res. - : Springer Science and Business Media LLC. - 1472-6963. ; 18 Journal article (peer-reviewed)abstract BackgroundClinical pathways can enhance care quality, promote patient safety and optimize resource utilization. However, they are infrequently utilized in intensive care. This study aimed to explain the implementation process of a clinical pathway based on a bottom-up approach in an intensive care context.MethodsThe setting was an 11-bed general intensive care unit in Sweden. An action research project was conducted to implement a clinical pathway for patients on mechanical ventilation. The project was managed by a local interprofessional core group and was externally facilitated by two researchers. Grounded theory was used by the researchers to explain the implementation process. The sampling in the study was purposeful and theoretical and included registered nurses (n31), assistant nurses (n26), anesthesiologists (n11), a physiotherapist (n1), first- and second-line managers (n2), and health records from patients on mechanical ventilation (n136). Data were collected from 2011 to 2016 through questionnaires, repeated focus groups, individual interviews, logbooks/field notes and health records. Constant comparative analysis was conducted, including both qualitative data and descriptive statistics from the quantitative data.ResultsA conceptual model of the clinical pathway implementation process emerged, and a central phenomenon, which was conceptualized as Struggling for a feasible tool,' was the core category that linked all categories. The phenomenon evolved from the Triggers' (Perceiving suboptimal practice' and Receiving external inspiration and support'), pervaded the Implementation process' (Contextual circumstances,' Processual circumstances' and Negotiating to achieve progress'), and led to the process Output' (Varying utilization' and Improvements in understanding and practice'). The categories included both facilitating and impeding factors that made the implementation process tentative and prolonged but also educational.ConclusionsThe findings provide a novel understanding of a bottom-up implementation of a clinical pathway in an intensive care context. Despite resonating well with existing implementation frameworks/theories, the conceptual model further illuminates the complex interaction between different circumstances and negotiations and how this interplay has consequences for the implementation process and output. The findings advocate a bottom-up approach but also emphasize the need for strategic priority, interprofessional participation, skilled facilitators and further collaboration.
15.	Lind, Anne-Li (author) Biomarkers for Better Understanding of the Pathophysiology and Treatment of Chronic Pain : Investigations of Human Biofluids 2017 Doctoral thesis (other academic/artistic)abstract Chronic pain affects 20 % of the global population, causes suffering, is difficult to treat, and constitutes a large economic burden for society. So far, the characterization of molecular mechanisms of chronic pain-like behaviors in animal models has not translated into effective treatments.In this thesis, consisting of five studies, pain patient biofluids were analyzed with modern proteomic methods to identify biomarker candidates that can be used to improve our understanding of the pathophysiology chronic pain and lead to more effective treatments.Paper I is a proof of concept study, where a multiplex solid phase-proximity ligation assay (SP-PLA) was applied to cerebrospinal fluid (CSF) for the first time. CSF reference protein levels and four biomarker candidates for ALS were presented. The investigated proteins were not altered by spinal cord stimulation (SCS) treatment for neuropathic pain. In Paper II, patient CSF was explored by dimethyl and label-free mass spectrometric (MS) proteomic methods. Twelve proteins, known for their roles in neuroprotection, nociceptive signaling, immune regulation, and synaptic plasticity, were identified to be associated with SCS treatment of neuropathic pain. In Paper III, proximity extension assay (PEA) was used to analyze levels of 92 proteins in serum from patients one year after painful disc herniation. Patients with residual pain had significantly higher serum levels of 41 inflammatory proteins. In Paper IV, levels of 55 proteins were analyzed by a 100-plex antibody suspension bead array (ASBA) in CSF samples from two neuropathic pain patient cohorts, one cohort of fibromyalgia patients and two control cohorts. CSF protein profiles consisting of levels of apolipoprotein C1, ectonucleotide pyrophosphatase/phosphodiesterase family member 2, angiotensinogen, prostaglandin-H2 D-isomerase, neurexin-1, superoxide dismutases 1 and 3 were found to be associated with neuropathic pain and fibromyalgia. In Paper V, higher CSF levels of five chemokines and LAPTGF-beta-1were detected in two patient cohorts with neuropathic pain compared with healthy controls.In conclusion, we demonstrate that combining MS proteomic and multiplex antibody-based methods for analysis of patient biofluid samples is a viable approach for discovery of biomarker candidates for the pathophysiology and treatment of chronic pain. Several biomarker candidates possibly reflecting systemic inflammation, lipid metabolism, and neuroinflammation in different pain conditions were identified for further investigation.
16.	Bjurling-Sjöberg, Petronella, et al. (author) Balancing intertwined responsibilities: A grounded theory study of teamwork in everyday intensive care unit practice 2017 In: Journal of Interprofessional Care. - : Informa UK Limited. - 1356-1820 .- 1469-9567. ; 31:2, s. 233-244 Journal article (peer-reviewed)abstract This study aimed to describe and explain teamwork and factors that influence team processes in everyday practice in an intensive care unit (ICU) from a staff perspective. The setting was a Swedish ICU. Data were collected from 38 ICU staff in focus groups with registered nurses, assistant nurses, and anaesthetists, and in one individual interview with a physiotherapist. Constant comparative analysis according to grounded theory was conducted, and to identify the relations between the emerged categories, the paradigm model was applied. The core category to emerge from the data was balancing intertwined responsibilities. In addition, eleven categories that related to the core category emerged. These categories described and explained the phenomenon's contextual conditions, causal conditions, and intervening conditions, as well as the staff actions/interactions and the consequences that arose. The findings indicated that the type of teamwork fluctuated due to circumstantial factors. Based on the findings and on current literature, strategies that can optimise interprofessional teamwork are presented. The analysis generated a conceptual model, which aims to contribute to existing frameworks by adding new dimensions about perceptions of team processes within an ICU related to staff actions/interactions. This model may be utilised to enhance the understanding of existing contexts and processes when designing and implementing interventions to facilitate teamwork in the pursuit of improving healthcare quality and patient safety.
17.	Krakau, Karolina, 1968-, et al. (author) Prediction of energy expenditure in patients with severe traumatic brain injury : A validation study by use of continuous indirect calorimetry and doubly labelled water Other publication (other academic/artistic)abstract Objective: The aim was to evaluate the accuracy of methods to predict energy expenditure (EE) in patients with severe traumatic brain injury (TBI). Method: To this prospective descriptive study, a small cohort of patients (n6) with isolated, severe TBI and an expected hospital stay of ≥2-3 months were included. The EE was measured at two intervals: by continuous indirect calorimetry during mechanical ventilation and by doubly labelled water from 3rd to 5th week post injury. Different equations for prediction of EE and a portable monitor, the SenseWear Armband were compared to the measured EE. Result: The majority of methods for predicting EE agreed poorly with the measured EE during indirect calorimetry period. A good agreement was found only with the three Penn-State equations, but two were biased according to Bland Altman analysis. The Penn-State equation from 1998 was the only valid predictive method, with a mean difference per day close to zero (+22 kcal), an excellent agreement (ICC 0.82) with 72% (n54/75) accurately assessed days (±10% of the measured EE) and with all patients within clinically acceptable levels, i.e. ±15% of the measured EE. During doubly labelled water period, observations were too few for any conclusive statement. Conclusion: These data support use of the Penn-State equation from 1998 to estimate EE in patients with severe TBI while on mechanical ventilation.

(author) Risk factors for ventilator-associated lower respiratory tract infection in COVID-19, a retrospective multicenter cohort study in Sweden 2024 In: Acta Anaesthesiologica Scandinavica. - : John Wiley & Sons. - 0001-5172 .- 1399-6576. ; 68:2, s. 226-235 Journal article (peer-reviewed)abstract Background: Ventilator-associated lower respiratory tract infections (VA-LRTI) increase morbidity and mortality in intensive care unit (ICU) patients. Higher incidences of VA-LRTI have been reported among COVID-19 patients requiring invasive mechanical ventilation (IMV). The primary objectives of this study were to describe clinical characteristics, incidence, and risk factors comparing patients who developed VA-LRTI to patients who did not, in a cohort of Swedish ICU patients with acute hypoxemic respiratory failure due to COVID-19. Secondary objectives were to decipher changes over the three initial pandemic waves, common microbiology and the effect of VA-LTRI on morbidity and mortality.Methods: We conducted a multicenter, retrospective cohort study of all patients admitted to 10 ICUs in southeast Sweden between March 1, 2020 and May 31, 2021 because of acute hypoxemic respiratory failure due to COVID-19 and were mechanically ventilated for at least 48 h. The primary outcome was culture verified VA-LRTI. Patient characteristics, ICU management, clinical course, treatments, microbiological findings, and mortality were registered. Logistic regression analysis was conducted to determine risk factors for first VA-LRTI.Results: Of a total of 536 included patients, 153 (28.5%) developed VA-LRTI. Incidence rate of first VA-LRTI was 20.8 per 1000 days of IMV. Comparing patients with VA-LRTI to those without, no differences in mortality, age, sex, or number of comorbidities were found. Patients with VA-LRTI had fewer ventilator-free days, longer ICU stay, were more frequently ventilated in prone position, received corticosteroids more often and were more frequently on antibiotics at intubation. Regression analysis revealed increased adjusted odds-ratio (aOR) for first VA-LRTI in patients treated with corticosteroids (aOR 2.64 [95% confidence interval [CI]] [1.31-5.74]), antibiotics at intubation (aOR 2.01 95% CI [1.14-3.66]), and days of IMV (aOR 1.05 per day of IMV, 95% CI [1.03-1.07]). Few multidrug-resistant pathogens were identified. Incidence of VA-LRTI increased from 14.5 per 1000 days of IMV during the first wave to 24.8 per 1000 days of IMV during the subsequent waves.Conclusion: We report a high incidence of culture-verified VA-LRTI in a cohort of critically ill COVID-19 patients from the first three pandemic waves. VA-LRTI was associated with increased morbidity but not 30-, 60-, or 90-day mortality. Corticosteroid treatment, antibiotics at intubation and time on IMV were associated with increased aOR of first VA-LRTI.

(author) Swallowing function in COVID-19 patients after invasive mechanical ventilation 2022 In: Archives of Rehabilitation Research and Clinical Translation. - : Elsevier. - 2590-1095. ; 4:1 Journal article (peer-reviewed)abstract Objective: To explore swallowing function and risk factors associated with delayed recovery of swallowing in patients with COVID-19 post–invasive mechanical ventilation using the Functional Oral Intake Scale (FOIS).Design: Longitudinal cohort study.Setting: Three secondary-level hospitals.Participants: Invasively ventilated patients (N=28) who were hospitalized with severe COVID-19 and referred to the hospitals’ speech and language pathology (SLP) departments after mechanical ventilation between March 5 and July 5, 2020 for an evaluation of swallowing function before commencing oral diet.Interventions: SLP assessment, advice, and therapy for dysphagia.Main Outcome Measures: Oral intake levels at baseline and hospital discharge according to the FOIS. Patients were stratified according to FOIS (1-5, dysphagia; 6-7, functional oral intake). Data regarding comorbidities, frailty, intubation and tracheostomy, proning, and SLP evaluation were collected.Results: Dysphagia was found in 71% of the patients at baseline (79% men; age, 61±12y; body mass index, 30±8 kg/m2). The median FOIS score at baseline was 2 (interquartile range [IQR], 1) vs 5 (IQR, 2.5) at hospital discharge. Patients with dysphagia were older (64±8.5y vs 53±16y; P=.019), had a higher incidence of hypertension (70% vs 12%; P=.006), and were ventilated invasively longer (16±7d vs 10±2d; P=.017) or had a tracheostomy (9±9d vs 1±2d; P=.03) longer. A negative association was found between swallowing dysfunction at bedside and days hospitalized (r=–0.471, P=.01), and number of days in the intensive care unit (ICU) (r=–0.48, P=.01).Conclusion: Dysphagia is prevalent in COVID-19 patients after invasive mechanical ventilation and is associated with number of days in hospital and number of days in the ICU. Swallowing function and tolerance of oral diet improved at discharge (P<.001).
20.	Bäckryd, Emmanuel, et al. (author) High levels of cerebrospinal fluid chemokines point to the presence of neuroinflammation in peripheral neuropathic pain : a cross-sectional study of 2 cohorts of patients compared with healthy controls 2017 In: Pain. - : Ovid Technologies (Wolters Kluwer Health). - 0304-3959 .- 1872-6623. ; 158:12, s. 2487-2495 Journal article (peer-reviewed)abstract Animal models suggest that chemokines are important mediators in the pathophysiology of neuropathic pain. Indeed, these substances have been called “gliotransmitters,” a term that illustrates the close interplay between glial cells and neurons in the context of neuroinflammation and pain. However, evidence in humans is scarce. The aim of the study was to determine a comprehensive cerebrospinal fluid (CSF) inflammatory profile of patients with neuropathic pain. Our hypothesis was that we would thereby find indications of a postulated on-going process of central neuroinflammation. Samples of CSF were collected from 2 cohorts of patients with neuropathic pain (n = 11 and n = 16, respectively) and healthy control subjects (n = 11). The samples were analyzed with a multiplex proximity extension assay in which 92 inflammation-related proteins were measured simultaneously (Proseek Multiplex Inflammation I; Olink Bioscience, Uppsala, Sweden). Univariate testing with control of false discovery rate, as well as orthogonal partial least squares discriminant analysis, were used for statistical analyses. Levels of chemokines CXCL6, CXCL10, CCL8, CCL11, CCL23 in CSF, as well as protein LAPTGF-beta-1, were significantly higher in both neuropathic pain cohorts compared with healthy controls, pointing to neuroinflammation in patients. These 6 proteins were also major results in a recent similar study in patients with fibromyalgia. The findings need to be confirmed in larger cohorts, and the question of causality remains to be settled. Because it has been suggested that prevalent comorbidities to chronic pain (eg, depression, anxiety, poor sleep, and tiredness) also are associated with neuroinflammation, it will be important to determine whether neuroinflammation is a common mediator.

(author) Factors that influence the use of ambulance in acute coronary syndrome. 2008 In: American heart journal. - Amsterdam : Elsevier BV. - 1097-6744 .- 0002-8703. ; 156:1, s. 170-6 Journal article (peer-reviewed)abstract BACKGROUND: National guidelines recommend activation of the emergency medical service by patients who have symptoms of acute coronary syndrome (ACS). In spite of this, only 50% to 60% of persons with myocardial infarction initiate care by using the emergency medical service. The aim of this study was to define factors influencing the use of ambulance in ACS. METHODS: The method used in this study was a national survey comprising intensive cardiac care units at 11 hospitals in Sweden; 1,939 patients with diagnosed ACS and symptom onset outside the hospital completed a questionnaire a few days after admission. RESULTS: Half of the patients went to the hospital by ambulance. Factors associated with ambulance use were knowledge of the importance of quickly seeking medical care and calling for an ambulance when having chest pain (odds ratio [OR] 3.61, 95% CI 2.43-5.45), abrupt onset of pain reaching maximum intensity within minutes (OR 2.08, 1.62-2.69), nausea or cold sweat (OR 2.02, 1.54-2.65), vertigo or near syncope (OR 1.63, 1.21-2.20), ST-elevation ACS (OR 1.58, 1.21-2.06), increasing age (per year) (OR 1.03, 1.02-1.04), previous history of heart failure (OR 2.48, 1.47-4.26), and distance to the hospital of >5 km (OR 2.0, 1.55-2.59). Those who did not call for an ambulance thought self-transport would be faster or did not believe they were sick enough. CONCLUSIONS: Symptoms, patient characteristics, ACS characteristics, and perceptions and knowledge were all associated with ambulance use in ACS. The fact that knowledge increases ambulance use and the need for behavioral change pose a challenge for health-care professionals.
22.	Krakau, Karolina, 1968-, et al. (author) Energy balance and metabolism after severe traumatic brain injury : A pilot study using doubly labelled water Other publication (other academic/artistic)abstract Objective: To explore the course of energy balance in patients with severe traumatic brain injury, from time of injury until twelve weeks post injury. Method: This prospective desriptive study included six patients with isolated, closed severe traumatic brain injury and an expected hospital stay of ≥2-3 months. Energy balance was calculated from energy intake compared to total energy expenditure measured by continuous indirect calorimetry and doubly labelled water. Clinical and laboratory variables with possible influence on metabolism and nutritional delivery were recorded simultaneously. Intermittent indirect calorimetry measurements were used to differentiate components of the energy expended. Results: Patients were roughly in energy balance while on mechanical ventilation, but in negative energy balance from the 3rd week post injury. The total energy expenditure then increased while the daily energy intake declined. Concurrent with this period were difficulties in retaining enteral and/or parenteral nutrition delivery routes until oral feeding was satisfactory. Nitrogen balance was back to normal at about 1.5 months and the inflammatory period with increased C-reactive protein levels continued for 12 to 58 days from time of injury. During the first and second month post injury, patients lost 8-19% of their initial body weight. Conclusion: Data suggests that negative energy balance after a severe TBI could not only be explained by the elevated metabolic rate and catabolism induced by the trauma, but also by difficulties in securing alternative nutritional routes in the distressed patient.
23.	Bergthorsdottir, Ragnhildur, 1971, et al. (author) Increased risk of hospitalization, intensive care and death due to covid-19 in patients with adrenal insufficiency : a Swedish nationwide study 2024 In: Journal of Internal Medicine. - : John Wiley & Sons. - 0954-6820 .- 1365-2796. ; 295:3, s. 322-330 Journal article (peer-reviewed)abstract Background: Patients with adrenal insufficiency (AI) have excess morbidity and mortality related to infectious disorders. Whether patients with AI have increased morbidity and mortality from COVID-19 is unknown.Methods: In this linked Swedish national register-based cohort study, patients with primary and secondary AI diagnosis were identified and followed from 1 January 2020 to 28 February 2021. They were compared with a control cohort from the general population matched 10:1 for age and sex. The following COVID-19 outcomes were studied: incidence of COVID-19 infection, rates of hospitalization, intensive care admission and death. Hazard ratios (HR) with 95% confidence intervals (95% CI) adjusted for socioeconomic factors and comorbidities were estimated using Cox regression analysis.Results: We identified 5430 patients with AI and 54,300 matched controls: There were 47.6% women, mean age was 57.1 (standard deviation 18.1) years, and the frequency of COVID-19 infection was similar, but the frequency of hospitalization (2.1% vs. 0.8%), intensive care (0.3% vs. 0.1%) and death (0.8% vs. 0.2%) for COVID-19 was higher in AI patients than matched controls. After adjustment for socioeconomic factors and comorbidities, the HR (95% CI) was increased for hospitalization (1.96, 1.59–2.43), intensive care admission (2.76, 1.49–5.09) and death (2.29, 1.60–3.28).Conclusion: Patients with AI have a similar incidence of COVID-19 infection to a matched control population, but a more than twofold increased risk of developing a severe infection or a fatal outcome. They should therefore be prioritized for vaccination, antiviral therapy and other appropriate treatment to mitigate hospitalization and death.
24.	Fagevik Olsén, Monika, 1964, et al. (author) Evaluation of Pressure Generated by Resistors From Different Positive Expiratory Pressure Devices 2015 In: Respiratory Care. - : Daedalus Enterprises. - 0020-1324 .- 1943-3654. ; 60:10, s. 1418-1423 Journal article (peer-reviewed)abstract BACKGROUND: Breathing exercises with positive expiratory pressure (PEP) are used to improve pulmonary function and airway clearance. Different PEP devices are available, but there have been no studies that describe the pressure generated by different resistors. The purpose of this study was to compare pressures generated from the proprietary resistor components of 4 commercial flow-dependent PEP valves with all other parameters kept constant. METHODS: Resistors from 4 flow-regulated PEP devices (Pep/Rmt system, Wellspect HealthCare; Pipe P breathing exerciser, Koo Medical Equipment; Mini-PEP, Philips Respironics [including resistors by Rusch]; and 15-mm endo-adapter, VBM Medizintechnik) were tested randomly by a blinded tester at constant flows of 10 and 18 L/min from an external gas system. All resistors were tested 3 times. RESULTS: Resistors with a similar diameter produced statistically significant different pressures at the same flow. The differences were smaller when the flow was 10 L/min compared with 18 L/min. The differences were also smaller when the diameter of the resistor was increased. The pressures produced by the 4 resistors of the same size were all significantly different when measuring 1.5- and 2.0-mm resistors at a flow of 10 L/min and 2.0-mm resistors at a flow of 18 L/min (P < .001). There were no significant differences between any of the resistors when testing sizes of 4.5 and 5.0 mm at either flow. The Mini-PEP and adapter resistors gave the highest pressures. CONCLUSIONS: Pressures generated by the different proprietary resistor components of 4 commercial PEP devices were not comparable, even though the diameter of the resistors is reported to be the same. The pressures generated were significantly different, particularly when using small-diameter resistors at a high flow. Therefore, the resistors may not be interchangeable. This is important information for clinicians, particularly when considering PEP for patients who do not tolerate higher pressures. (C) 2015 Daedalus Enterprises
25.	Schell, Carl Otto, et al. (author) Essential Emergency and Critical Care : a consensus among global clinical experts. 2021 In: BMJ Global Health. - : BMJ Publishing Group Ltd. - 2059-7908. ; 6:9 Journal article (peer-reviewed)abstract BACKGROUND: Globally, critical illness results in millions of deaths every year. Although many of these deaths are potentially preventable, the basic, life-saving care of critically ill patients are often overlooked in health systems. Essential Emergency and Critical Care (EECC) has been devised as the care that should be provided to all critically ill patients in all hospitals in the world. EECC includes the effective care of low cost and low complexity for the identification and treatment of critically ill patients across all medical specialties. This study aimed to specify the content of EECC and additionally, given the surge of critical illness in the ongoing pandemic, the essential diagnosis-specific care for critically ill patients with COVID-19.METHODS: In a Delphi process, consensus (>90% agreement) was sought from a diverse panel of global clinical experts. The panel iteratively rated proposed treatments and actions based on previous guidelines and the WHO/ICRC's Basic Emergency Care. The output from the Delphi was adapted iteratively with specialist reviewers into a coherent and feasible package of clinical processes plus a list of hospital readiness requirements.RESULTS: The 269 experts in the Delphi panel had clinical experience in different acute medical specialties from 59 countries and from all resource settings. The agreed EECC package contains 40 clinical processes and 67 requirements, plus additions specific for COVID-19.CONCLUSION: The study has specified the content of care that should be provided to all critically ill patients. Implementing EECC could be an effective strategy for policy makers to reduce preventable deaths worldwide.
