Forskningsöversikt (refereegranskat)abstract
- Purpose: We critically examined the evidence supporting the widely accepted notion that patients undergoing continent urinary tract reconstruction after cystectomy experience superior quality of life outcomes than patients receiving a conduit. Materials and Methods: Based on a comprehensive MEDLINE literature search we retrieved and evaluated all full-length articles published in the English, French, German, Italian and Spanish languages comparing conduit diversion with continent cutaneous diversion and/or orthotopic bladder substitution with respect to quality of life or similar concepts. All studies were rated according to the International Consultation on Urological Diseases modification of Oxford Center for Evidence-Based Medicine levels of evidence. Results: The literature on quality of life after radical cystectomy for bladder cancer was rather extensive but generally of questionable quality. The main problems were flaws in the patient materials and methodologies used. To our knowledge not a single randomized, controlled study exists in the field. Because only few articles achieved a level of evidence better than III, the International Consultation on Urological Diseases rating system does not allow further differentiation among studies. Most studies showed that overall quality of life after cystectomy remained good in most patients irrespective of urinary diversion type. Conclusions: Existing studies are unable to prove that continent reconstruction after radical cystectomy is superior to conduit diversion. This review emphasizes the importance of performing well designed studies in the future.

- The objective of this review is to examine the published data regarding quality of life (QOL) in patients with bladder cancer. Not a single, randomized controlled trial exists. Most studies are retrospective, cross-sectional, and have serious methodological flaws. There is no single QOL tool preferably used in bladder cancer. While there is no long-term data after therapy for Superficial cancer, most investigations compared the impact of different forms of urinary diversion on QOL. In contrast to the prevailing notion that patients who underwent cystectomy undergoing continent urinary reconstruction have superior QOL than those receiving a conduit, existing reports fail to show significant advantages of one technique over the other.

- The Department of Urology in Lund, Sweden, has a long association with innovations in reconstructive urology. The authors from that department describe their experience over a long period with orthotopic bladder substitution and continent cutaneous urinary diversion. They conclude that continent urinary tract reconstruction is associated with a high incidence of early and late complications. They also found that for storage and emptying, their Lundiana pouch was superior to the Goldwasser neobladder. OBJECTIVE: To assess the early and late complications and functional results in patients undergoing continent reconstruction of the urinary tract, i.e. orthotopic bladder substitution (OBS) or continent cutaneous diversion (CCD). PATIENTS AND METHODS: The medical records of all patients undergoing OBS (Goldwasser technique) or CCD ('Lundiana' technique) for malignant or benign disease during 1987-1999 and followed to December 2001 were reviewed. There were 67 patients with neobladders, 77 with a Lundiana pouch who had undergone radical cystectomy and 22 with a Lundiana pouch operated for benign disorders. RESULTS: Early complications requiring reoperation occurred in 12% of the cystectomy group, with no difference with type of reconstruction, and in 10% with benign diseases. Four patients (3%) undergoing radical cystectomy died from early cardiovascular complications, two after surgery for intra-abdominal complications. Intestinally related complications and wound dehiscence requiring re-operation occurred in nine and six patients, respectively. The incidence of late complications requiring open surgery was 22% and 23% after cystectomy with OBS and CCD, respectively. The value in patients with benign diseases undergoing CCD was also 23%. Stone formation in the pouch was common, occurring in 12% in patients with OBS and in 10% after CCD. The pouch perforated or ruptured in four patients. The incidence of uretero-intestinal stricture using the Le Duc technique was 2.4% and renal function was well preserved. The incidence of revisional surgery of the Lundiana pouch outlet for incontinence was low and all patients but four were continent. The functional outcome in patients with OBS was less good; some needed pouch augmentation or an artificial urinary sphincter. Most patients used incontinence products and many needed clean intermittent self-catheterization. CONCLUSION: Continent urinary tract reconstruction is associated with a high incidence of early and late complications. For storage and emptying, the CCD Lundiana pouch is superior to the OBS of Goldwasser.

- OBJECTIVES: To compare two patient populations with assumed cultural differences undergoing radical cystectomy and orthotopic bladder substitution to determine whether these translate into differences in the answers to self-report instruments. METHODS: The questionnaires Functional Assessment of Cancer Therapy-Bladder Cancer (FACT-BL), consisting of a general version (FACT-G) and a bladder cancer specific module, and Hospital Anxiety and Depression Scale (HADS) were used preoperatively and 3 and 12 months postoperatively to assess patient well-being, urologic symptoms, depression, and anxiety in 29 and 32 Swedish and Egyptian male patients, respectively. RESULTS: Significant differences were found between the two groups. Higher FACT-G scores (ie, better outcomes) were obtained in the Swedish patients, both preoperatively and 3 months postoperatively, but not after 12 months. Differences were also seen in the urogenital assessment provided by the FACT-BL module. HADS revealed more depression among the Egyptian patients throughout the study period. Also, anxiety was more common preoperatively and 3 months postoperatively in the Egyptian patients, but not after 12 months. CONCLUSIONS: Swedish men scored better than Egyptian men on the FACT-BL and HADS, although the latter improved with time after surgery. These results show that patient-assessed outcomes differ in patients from different sociocultural backgrounds. This should be recognized when analyzing results from comparative studies. Also, the use of culture-fair instruments is important when assessing patients with different sociocultural backgrounds.

- Objective To compare the quality of life (QoL) in men after radical cystectomy who had either a continent cutaneous diversion or orthotopic bladder substitution. Patients and methods Eighty men with at least 6 months of follow-up and with no signs of recurrent disease after radical cystectomy for bladder carcinoma, and who had either a continent cutaneous diversion or orthotopic bladder substitution, were sent two types of questionnaire, the Functional Assessment of Cancer Therapy-Bladder Cancer (FACT-Bl) and the Hospital Anxiety and Depression Scale (HADS), to determine their QoL. Results The FACT-Bl and HADS questionnaires were returned by 90% and 71% of the patients, respectively ( P < 0.05). In the replies to the generic version of FACT-Bl there were no differences between the groups in any domain, the scores being high in all. In questions covering intestinal, urinary and sexual items, patients with continent diversion had less trouble controlling urine (P< 0.0001), had to empty less often (P < 0.001), and had fewer symptoms when emptying (P < 0.05). Patients with neobladders had a better appreciation of appearance and better preserved erectile function (both P < 0.05). In the answers to the HADS, the mean scores were low (within the normal ranges) and did not differ between the groups. Conclusion Using two instruments tested for validity and reliability, there were no differences between patients with continent diversion and those with orthotopic substitution.

- In chest tomosynthesis, low-dose projections collected over a limited angular range are used for reconstruction of section images of the chest, resulting in a reduction of disturbing anatomy at a moderate increase in radiation dose compared to chest radiography. In a previous study, we investigated the effects of learning with feedback on the detection of pulmonary nodules in chest tomosynthesis. Six observers with varying degrees of experience of chest tomosynthesis analyzed tomosynthesis cases for presence of pulmonary nodules. The cases were analyzed before and after learning with feedback. Multidetector computed tomography (MDCT) was used as reference. The differences in performance between the two readings were calculated using the jackknife alternative free-response receiver operating characteristics (JAFROC-2) as primary measure of detectability. Significant differences between the readings were found only for observers inexperienced in chest tomosynthesis. The purpose of the present study was to extend the statistical analysis of the results of the previous study, including JAFROC-1 analysis and FROC curves in the analysis. The results are consistent with the results of the previous study and, furthermore, JAFROC-1 gave lower p-values than JAFROC-2 for the observers who improved their performance after learning with feedback. © 2011 SPIE.

Dynamic changes in immune gene co-expression networks predict development of type 1 diabetes

Tidskriftsartikel (refereegranskat)abstract
- Significant progress has been made in elucidating genetic risk factors influencing Type 1 diabetes (T1D); however, features other than genetic variants that initiate and/or accelerate islet autoimmunity that lead to the development of clinical T1D remain largely unknown. We hypothesized that genetic and environmental risk factors can both contribute to T1D through dynamic alterations of molecular interactions in physiologic networks. To test this hypothesis, we utilized longitudinal blood transcriptomic profiles in The Environmental Determinants of Diabetes in the Young (TEDDY) study to generate gene co-expression networks. In network modules that contain immune response genes associated with T1D, we observed highly dynamic differences in module connectivity in the 600 days (~ 2 years) preceding clinical diagnosis of T1D. Our results suggest that gene co-expression is highly plastic and that connectivity differences in T1D-associated immune system genes influence the timing and development of clinical disease.

- A lead generation campaign identified indole-based sPLA2-X inhibitors with a promising selectivity profile against other sPLA2 isoforms. Further optimization of sPLA2 selectivity and metabolic stability resulted in the design of (-)-17, a novel, potent, and selective sPLA2-X inhibitor with an exquisite pharmacokinetic profile characterized by high absorption and low clearance, and low toxicological risk. Compound (-)-17 was tested in an ApoE-/- murine model of atherosclerosis to evaluate the effect of reversible, pharmacological sPLA2-X inhibition on atherosclerosis development. Despite being well tolerated and achieving adequate systemic exposure of mechanistic relevance, (-)-17 did not significantly affect circulating lipid and lipoprotein biomarkers and had no effect on coronary function or histological markers of atherosclerosis.

A Comparison of Rule-based Analysis with Regression Methods in Understanding the Risk Factors for Study Withdrawal in a Pediatric Study

Tidskriftsartikel (refereegranskat)abstract
- Regression models are extensively used in many epidemiological studies to understand the linkage between specific outcomes of interest and their risk factors. However, regression models in general examine the average effects of the risk factors and ignore subgroups with different risk profiles. As a result, interventions are often geared towards the average member of the population, without consideration of the special health needs of different subgroups within the population. This paper demonstrates the value of using rule-based analysis methods that can identify subgroups with heterogeneous risk profiles in a population without imposing assumptions on the subgroups or method. The rules define the risk pattern of subsets of individuals by not only considering the interactions between the risk factors but also their ranges. We compared the rule-based analysis results with the results from a logistic regression model in The Environmental Determinants of Diabetes in the Young (TEDDY) study. Both methods detected a similar suite of risk factors, but the rule-based analysis was superior at detecting multiple interactions between the risk factors that characterize the subgroups. A further investigation of the particular characteristics of each subgroup may detect the special health needs of the subgroup and lead to tailored interventions.

Tidskriftsartikel (refereegranskat)abstract
- Background: Exchanging experiences of patient and public involvement (PPI) can bring insights into why, how and when PPI is most effective. The aim of this study was to explore the experiences of patient research partners (PRPs) and researchers engaged in a co-creative long-term collaboration in cancer research.Methods: The aim and procedures of this study were jointly decided upon by PRPs and researchers. The PRPs included former patients treated for cancer and significant others of the same target group. The participants (11 PRPs, 6 researchers) took part in semi-structured telephone interviews. The interviews were analysed using qualitative content analysis by a researcher who had no prior relationships with the participants.Results: . Reasons for investing in the collaboration included the desire to improve cancer care and to make use of own negative experiences. Benefits of participating included a positive impact on the PRPs' psychosocial adjustment to the illness. Moreover, the researchers highlighted that working together with the PRPs made the research feel more meaningful. The participants reported that the collaboration improved the relevance and acceptability of the research. Having a shared goal, a clear but yet accommodating structure, as well as an open and trustful working atmosphere were recognised as elements of success. The PRPs furthermore emphasized the importance of seeing that their input mattered. Among the few challenges raised were the distance to the meeting venues for some PRPs and a limited diversity among participants.Conclusions: This study identified factors essential to researchers and clinicians attempting to engage the public in research. Our results suggest that for successful patient involvement, the purpose and format of the collaboration should be clear to both PRPs and researchers. A clear but yet accommodating structure and keen leadership emerged as key factors to create a sense of stability and a trustful atmosphere. Furthermore, providing regular feedback on how PRPs input is implemented is important for PRPs to stay committed over time.

Tidskriftsartikel (refereegranskat)abstract
- The aim was to study alterations of bacterial communities in patients undergoing hip or knee arthroplasty to assess the impact of chlorhexidine gluconate soap decolonisation and systemic antibiotic prophylaxis. A Swedish multicentre, prospective collection of samples obtained from elective arthroplasty patients (n = 83) by swabbing anterior nares, skin sites in the groin and the site of planned surgery, before and after arthroplasty surgery, was analysed by 16S rRNA (V3-V4) gene sequencing and a complementary targeted tuf gene sequencing approach to comprehensively characterise alterations in staphylococcal communities. Significant reductions in alpha diversity was detected for both bacterial (p = 0.04) and staphylococcal (p = 0.03) groin communities after arthroplasty surgery with significant reductions in relative Corynebacterium (p = 0.001) abundance and Staphylococcus hominis (p = 0.01) relative staphylococcal abundance. In nares, significant reductions occurred for Staphylococcus hominis (p = 0.02), Staphylococcus haemolyticus (p = 0.02), and Staphylococcus pasteuri (p = 0.003) relative to other staphylococci. Staphylococcus aureus colonised 35% of anterior nares before and 26% after arthroplasty surgery. Staphylococcus epidermidis was the most abundant staphylococcal species at all sampling sites. No bacterial genus or staphylococcal species increased significantly after arthroplasty surgery. Application of a targeted tuf gene sequencing approach provided auxiliary staphylococcal community profiles and allowed species-level characterisation directly from low biomass clinical samples.

-
Tidskriftsartikel (refereegranskat)abstract
- The role of diet in type 1 diabetes development is poorly understood. Metabolites, which reflect dietary response, may help elucidate this role. We explored metabolomics and lipidomics differences between 352 cases of islet autoimmunity (IA) and controls in the TEDDY (The Environmental Determinants of Diabetes in the Young) study. We created dietary patterns reflecting pre-IA metabolite differences between groups and examined their association with IA. Secondary outcomes included IA cases positive for multiple autoantibodies (mAb+). The association of 853 plasma metabolites with outcomes was tested at seroconversion to IA, just prior to seroconversion, and during infancy. Key compounds in enriched metabolite sets were used to create dietary patterns reflecting metabolite composition, which were then tested for association with outcomes in the nested case-control subset and the full TEDDY cohort. Unsaturated phosphatidylcholines, sphingomyelins, phosphatidylethanolamines, glucosylceramides, and phospholipid ethers in infancy were inversely associated with mAb+ risk, while dicarboxylic acids were associated with an increased risk. An infancy dietary pattern representing higher levels of unsaturated phosphatidylcholines and phospholipid ethers, and lower sphingomyelins was protective for mAb+ in the nested case-control study only. Characterization of this high-risk infant metabolomics profile may help shape the future of early diagnosis or prevention efforts. © 2019, The Author(s).

- OBJECTIVE: Assessment of the predictive power of The Environmental Determinants of Diabetes in the Young (TEDDY)-identified risk factors for islet autoimmunity (IA), the type of autoantibody appearing first, and type 1 diabetes (T1D).RESEARCH DESIGN AND METHODS: A total of 7,777 children were followed from birth to a median of 9.1 years of age for the development of islet autoantibodies and progression to T1D. Time-dependent sensitivity, specificity, and receiver operating characteristic (ROC) curves were calculated to provide estimates of their individual and collective ability to predict IA and T1D.RESULTS: HLA genotype (DR3/4 vs. others) was the best predictor for IA (Youden's index J = 0.117) and single nucleotide polymorphism rs2476601, in PTPN22, was the best predictor for insulin autoantibodies (IAA) appearing first (IAA-first) (J = 0.123). For GAD autoantibodies (GADA)-first, weight at 1 year was the best predictor (J = 0.114). In a multivariate model, the area under the ROC curve (AUC) was 0.678 (95% CI 0.655, 0.701), 0.707 (95% CI 0.676, 0.739), and 0.686 (95% CI 0.651, 0.722) for IA, IAA-first, and GADA-first, respectively, at 6 years. The AUC of the prediction model for T1D at 3 years after the appearance of multiple autoantibodies reached 0.706 (95% CI 0.649, 0.762).CONCLUSIONS: Prediction modeling statistics are valuable tools, when applied in a time-until-event setting, to evaluate the ability of risk factors to discriminate between those who will and those who will not get disease. Although significantly associated with IA and T1D, the TEDDY risk factors individually contribute little to prediction. However, in combination, these factors increased IA and T1D prediction substantially.

Tidskriftsartikel (refereegranskat)abstract
- INTRODUCTION: Many depressed patients do not achieve remission with available treatments. Anhedonia is a common residual symptom associated with treatment resistance as well as low function and quality of life. There are currently no specific and effective treatments for anhedonia. Some trials have shown that dopamine agonist pramipexole is efficacious for treating depression, but more data is needed before it could become ready for clinical prime time. Given its mechanism of action, pramipexole might be a useful treatment for a depression subtype characterised by significant anhedonia and lack of motivation-symptoms associated with dopaminergic hypofunction. We recently showed, in an open-label pilot study, that add-on pramipexole is a feasible treatment for depression with significant anhedonia, and that pramipexole increases reward-related activity in the ventral striatum. We will now confirm or refute these preliminary results in a randomised controlled trial (RCT) and an open-label follow-up study. METHODS AND ANALYSIS: Eighty patients with major depression (bipolar or unipolar) or dysthymia and significant anhedonia according to the Snaith Hamilton Pleasure Scale (SHAPS) are randomised to either add-on pramipexole or placebo for 9 weeks. Change in anhedonia symptoms per the SHAPS is the primary outcome, and secondary outcomes include change in core depressive symptoms, apathy, sleep problems, life quality, anxiety and side effects. Accelerometers are used to assess treatment-associated changes in physical activity and sleep patterns. Blood and brain biomarkers are investigated as treatment predictors and to establish target engagement. After the RCT phase, patients continue with open-label treatment in a 6-month follow-up study aiming to assess long-term efficacy and tolerability of pramipexole. ETHICS AND DISSEMINATION: The study has been approved by the Swedish Ethical Review Authority and the Swedish Medical Products Agency. The study is externally monitored according to Good Clinical Practice guidelines. Results will be disseminated via conference presentations and peer-reviewed publications. TRIAL REGISTRATION NUMBER: NCT05355337 and NCT05825235.

Analgesic antipyretic use among young children in the TEDDY study : No association with islet autoimmunity
- 2017
-
Ingår i: BMC Pediatrics. - : Springer Science and Business Media LLC. - 1471-2431. ; 17:1
-
Tidskriftsartikel (refereegranskat)abstract
- Background: The use of analgesic antipyretics (ANAP) in children have long been a matter of controversy. Data on their practical use on an individual level has, however, been scarce. There are indications of possible effects on glucose homeostasis and immune function related to the use of ANAP. The aim of this study was to analyze patterns of analgesic antipyretic use across the clinical centers of The Environmental Determinants of Diabetes in the Young (TEDDY) prospective cohort study and test if ANAP use was a risk factor for islet autoimmunity. Methods: Data were collected for 8542 children in the first 2.5 years of life. Incidence was analyzed using logistic regression with country and first child status as independent variables. Holm's procedure was used to adjust for multiplicity of intercountry comparisons. Time to autoantibody seroconversion was analyzed using a Cox proportional hazards model with cumulative analgesic use as primary time dependent covariate of interest. For each categorization, a generalized estimating equation (GEE) approach was used. Results: Higher prevalence of ANAP use was found in the U.S. (95.7%) and Sweden (94.8%) compared to Finland (78.1%) and Germany (80.2%). First-born children were more commonly given acetaminophen (OR 1.26; 95% CI 1.07, 1.49; p = 0.007) but less commonly Non-Steroidal Anti-inflammatory Drugs (NSAID) (OR 0.86; 95% CI 0.78, 0.95; p = 0.002). Acetaminophen and NSAID use in the absence of fever and infection was more prevalent in the U.S. (40.4%; 26.3% of doses) compared to Sweden, Finland and Germany (p < 0.001). Acetaminophen or NSAID use before age 2.5 years did not predict development of islet autoimmunity by age 6 years (HR 1.02, 95% CI 0.99-1.09; p = 0.27). In a sub-analysis, acetaminophen use in children with fever weakly predicted development of islet autoimmunity by age 3 years (HR 1.05; 95% CI 1.01-1.09; p = 0.024). Conclusions: ANAP use in young children is not a risk factor for seroconversion by age 6 years. Use of ANAP is widespread in young children, and significantly higher in the U.S. compared to other study sites, where use is common also in absence of fever and infection.

Comparative genomics of Staphylococcus epidermidis from prosthetic : from prosthetic-joint infections and nares highlights genetic traits associated with antimicrobial resistance, not virulence

Tidskriftsartikel (refereegranskat)abstract
- There is increased awareness of the worldwide spread of specific epidemic multidrug-resistant (MDR) lineages of the human commensal Staphylococcus epidermidis. Here, using bioinformatic analyses accounting for population structure, we determined genomic traits (genes, SNPs and k-mers) that distinguish S. epidermidis causing prosthetic-joint infections (PJIs) from commensal isolates from nares, by analysing whole-genome sequencing data from S. epidermidis from PJIs prospectively collected over 10 years in Sweden, and contemporary S. epidermidis from the nares of patients scheduled for arthroplasty surgery. Previously suggested virulence determinants and the presence of genes and mutations linked to antimicrobial resistance (AMR) were also investigated. Publicly available S. epidermidis sequences were used for international extrapolation and validation of findings. Our data show that S. epidermidis causing PJIs differed from nasal isolates not by virulence but by traits associated with resistance to compounds used in prevention of PJIs: β-lactams, aminoglycosides and chlorhexidine. Almost a quarter of the PJI isolates did not belong to any of the previously described major nosocomial lineages, but the AMR-related traits were also over-represented in these isolates, as well as in international S. epidermidis isolates originating from PJIs. Genes previously associated with virulence in S. epidermidis were over-represented in individual lineages, but failed to reach statistical significance when adjusted for population structure. Our findings suggest that the current strategies for prevention of PJIs select for nosocomial MDR S. epidermidis lineages that have arisen from horizontal gene transfer of AMR-related traits into multiple genetic backgrounds.

Lower activation of caspase-1 by Staphylococcus epidermidis isolated from prosthetic joint infections compared to commensals
- 2018

Tidskriftsartikel (refereegranskat)abstract
- Nosocomial sequence types of Staphylococcus epidermidis dominate in prosthetic joint infections. We examined caspase-1 activation in human neutrophils after incubation with Staphylococcus epidermidis isolated from prosthetic joint infections and normal skin flora. Active caspase-1 was lower after incubation with isolates from prosthetic joint infections than after incubation with commensal isolates. Both host and isolate dependent differences in active caspase-1 were noted. Our results indicate that there might be a host-dependent incapacity to elicit a strong caspase-1 response towards certain strains of S. epidermidis. Further experiments with a larger number of individuals are warranted.

- Staphylococcus epidermidis, ubiquitous in the human nasal and skin microbiota, is a common causative microorganism in prosthetic joint infections (PJIs). A high proportion of PJI isolates have been shown to harbor genetic traits associated with resistance to/tolerance of agents used for antimicrobial prophylaxis in joint arthroplasties. These traits were found within multidrug-resistant S. epidermidis (MDRSE) lineages of multiple genetic backgrounds. In this study, the aim was to study whether MDRSE lineages previously associated with PJIs are present in the nasal and skin microbiota of patients planned for arthroplasty surgery but before hospitalization. We cultured samples from nares, inguinal creases, and skin over the hip or knee (dependent on the planned procedure) taken two weeks (median) prior to admittance to the hospital for total joint arthroplasty from 66 patients on agar plates selecting for methicillin resistance. S. epidermidis colonies were identified and tested for the presence of mecA. Methicillin-resistant S. epidermidis (MRSE) were characterized by Illumina-based whole-genome sequencing. Using this method, we found that 30/66 (45%) of patients were colonized with MRSE at 1-3 body sites. A subset of patients, 10/66 (15%), were colonized with MDRSE lineages associated with PJIs. The qacA gene was identified in MRSE isolates from 19/30 (63%) of MRSE colonized patients, whereas genes associated with aminoglycoside resistance were less common, found in 11/30 (37%). We found that MDRSE lineages previously associated with PJIs were present in a subset of patients' pre-admission microbiota, plausibly in low relative abundance, and may be selected for by the current prophylaxis regimen comprising whole-body cleansing with chlorhexidine-gluconate containing soap. To further lower the rate of S. epidermidis PJIs, the current prophylaxis may need to be modified, but it is important for possible perioperative MDRSE transmission events and specific risk factors for MDRSE PJIs to be investigated before reevaluating antimicrobial prophylaxis.

Molecular epidemiology of Staphylococcus epidermidis in prosthetic joint infections
- 2019

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Staphylococcus epidermidis is ubiquitous in the human microbiota, but also an important pathogen in healthcare-associated infections, such as prosthetic joint infections (PJIs). In this thesis, aspects of the molecular epidemiology of S. epidermidis in PJIs were investigated with the aim of improving our understanding of the pre- and perioperative measures required to reduce the incidence of S. epidermidis PJIs.In Paper I, S. epidermidis retrieved from air sampling in the operating field during arthroplasty was characterized by multilocus sequence typing and antibiotic susceptibility testing. No isolates belonging to sequence types (STs) 2 and 215, previously associated with PJIs, were found in the air of the operating field. During air sampling, several Staphylococcus pettenkoferi isolates were identified, and as a spin-off of Paper I, the genomic relatedness of these isolates to S. pettenkoferi isolates from blood cultures was described in Paper II.In Paper III, genetic traits distinguishing S. epidermidis isolated from PJIs were determined using genome-wide association study accounting for population effects after whole-genome sequencing (WGS) of a population- based 10-year collection of S. epidermidis isolates from PJIs and of nasal isolates retrieved from patients scheduled for arthroplasty. Genes associated with antimicrobial agents used for prophylaxis in arthroplasty, i.e., beta-lactam antibiotics, aminoglycosides, and chlorhexidine, were associated with PJI origin. S. epidermidis from PJIs were dominated by the ST2a, ST2b, ST5, and ST215 lineages.In Paper IV, selective agar plates were used to investigate colonization with methicillin resistant S. epidermidis (MRSE) in patients scheduled for arthroplasty. MRSE were further characterized by WGS. A subset of patients was found to harbour PJI-associated S. epidermidis lineages in their microbiota before hospitalization, but no isolates belonging to the ST2a lineage nor any rifampicin-resistant isolates were retrieved.

Staphylococcus epidermidis from prosthetic joint infections induces lower IL-1 release from human neutrophils than isolates from normal flora
- 2018
-
Ingår i: Acta Pathologica, Microbiologica et Immunologica Scandinavica (APMIS). - : Wiley-Blackwell Publishing Inc.. - 0903-4641 .- 1600-0463. ; 126:8, s. 678-684

Tidskriftsartikel (refereegranskat)abstract
- The aim of this study was to test the hypothesis that Staphylococcus epidermidis isolated from prosthetic joint infections (PJIs) differs from S.epidermidis isolated from normal flora in terms of its capacity to induce activation of caspase-1 and release of IL-1 in human neutrophils. The amount of active caspase-1 was determined over 6h by detecting Ac-YVAD-AMC fluorescence in human neutrophils incubated with S.epidermidis isolates from PJIs (ST2) or normal flora. The amount of IL-1 was detected by ELISA in neutrophil supernatants after 6h of incubation. Mean IL-1 release was lower after incubation with S.epidermidis from PJIs compared to isolates from normal flora, but no statistically significant difference was found in active caspase-1. Substantial inter-individual differences in both active caspase-1 and IL-1 were noted. These results suggest that evasion of innate immune response, measured as reduced capacity to induce release of IL-1 from human neutrophils, might be involved in the predominance of ST2 in S.epidermidis PJIs, but that other microbe-related factors are probably also important.

COVID-19 related individual work, managerial factors and exhaustion among general practitioners in Sweden : A cross-sectional study
- 2023
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Background: A Swedish study found that more than 16% of general practitioners (GPs) had exhaustion in spring 2021. A knowledge gap remains about the impact of COVID-19 related individual work and managerial factors on exhaustion among Swedish GPs. This study therefore explores the association between exhaustion and COVID-19 pandemic related individual work and managerial factors among Swedish GPs who managed COVID-19 patients, compared to those GPs who did not. Methods: Cross-sectional data was drawn from the Longitudinal Occupational Health survey in Health Care Sweden study, which included a representative sample of practicing doctors in Sweden. The sample consisted of 6699 doctors with a response rate of 41.2%. This study constitutes a sample of doctors who reported working in primary care facilities at the time of data collection reaching 1013 GPs. The Burnout Assessment Tool was used to assess the level of exhaustion. Questions were also asked about pandemic related, individual work and managerial factors. The data was analysed using descriptive statistics, and multivariate logistic regression.Results: The results showed that moral and emotional distress, excess workload and perceived unsatisfactory management (supportive, work environment and clinical management) increased the risk of GPs who managed COVID-19 patients reporting exhaustion. Furthermore, the results showed that satisfactory management can to some extent protect against the negative effects of moral and emotional distress and excess workload. Conclusions: COVID-19 related individual work and managerial factors had a significant impact on the mental health of GPs who managed COVID-19 patients during the pandemic. In the aftermath of the COVID-19 pandemic and in preparation for future major crises that have a high impact on healthcare, there is a need to investigate the measures that can be taken to enable GPs to carry out their work, while maintaining their health.

Tidskriftsartikel (refereegranskat)abstract
- Introduction A significant number of international studies show that general practitioners (GPs) suffered from burnout when working during the COVID-19 pandemic. A Swedish study found that more than 16% of GPs had exhaustion in spring 2021. Exhaustion can be regarded as an initial stage of burnout. A knowledge gap remains on GPs´ working conditions, the impact of management during the pandemic and how it was associated with exhaustion. This study aims to explore the association between severe symptoms of exhaustion and COVID-19 pandemic-related work and managerial factors among Swedish GPs and whether managerial factors have an impact on the association between exhaustion and COVID-19-related work factors.Methods Cross-sectional data was drawn from the Longitudinal Occupational Health survey in Health Care Sweden (LOHHCS), which included a representative sample of practicing doctors in Sweden. The sample consisted of 6699 doctors with a response rate of 41.2%. This study constitutes a sample of doctors who reported working in primary care facilities at the time of data collection, i.e. 1013 GPs. The Burnout Assessment Tool (BAT) was used to assess severe symptoms of exhaustion. Questions were also asked about pandemic-related work and managerial factors. The data was analysed using descriptive statistics and multivariate logistic regression to identify the association between exhaustion, work and managerial factors.Results The multivariate analysis showed that GPs who managed COVID-19 patients were about twice as likely to report severe symptoms of exhaustion. Further, GPs who reported that management was unsupportive, provided unsatisfactory working conditions and unsatisfactory policies for patient prioritisation were between two and four times more likely to report severe symptoms of exhaustion.Conclusions COVID-19-related work and managerial factors had a significant impact on the mental health of GPs. Furthermore, the potentially protective effect that satisfactory management actions had on mental health was limited. In the aftermath of the COVID-19 pandemic and in preparation for future major crises that have a high impact on healthcare, there is a need to investigate the measures that can be taken to enable GPs to carry out their work, while maintaining their wellbeing.

How general practitioners used job crafting strategies during the COVID-19 pandemic in Sweden
- 2024
-
Ingår i: Scandinavian Journal of Primary Health Care. - United Kingdom : Taylor & Francis Group. - 0281-3432 .- 1502-7724. ; 42:2, s. 276-286, s. 385-

Tidskriftsartikel (refereegranskat)abstract
- Objective: General practitioners (GPs) played a crucial role in limiting the impact of the COViD-19 pandemic, and many GPs experienced they did not have the prerequisites to provide adequate care. However, GPs developed approaches that helped them to provide care to patients through various job crafting strategies. The aim of this study is to identify how job crafting strategies were deployed by GPs at the beginning of the COViD-19 pandemic in Sweden and the significance of the strategies on their work situation. Design: A qualitative design with semi-structured interviews. The data was analysed using qualitative content analysis with job crafting as the conceptual framework for the analysis process. Setting: Primary healthcare in five healthcare regions in sweden. Subjects: Fourteen GPs participated in individual interviews. Results: In their endeavours to organise and provide care, GPs shaped the task, relational and cognitive boundaries of their work. GPs felt proud about finding new ways of working when given room to manoeuvre. Intensified collaboration between healthcare professionals made GPs more confident in their clinical work. GPs expressed that they consequently felt stronger in their professional role through what they accomplished in the organisation of care. Conclusions/Implications: The results suggest that the job crafting strategies GPs used were meaningful to them in clinical practice. Knowledge about how GPs’ job crafting strategies were deployed might be useful for healthcare organisations in preparing for future health crises. Taking advantage of GPs’ experiences and strategies is considered important for promoting sustainable working conditions for GPs in the future.

The patient with bladder cancer. From symptoms, through treatment, with special reference to psychosocial consequences of radical cystectomy
- 1997
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Factors determining patient`s and doctor`s delay in diagnosis of bladder cancer were type of initial symptoms, level of health service first consulted and number of steps in the referral system. No correlation was found between psychosocial factors and patient`s delay. In retrospective studies after cystectomy for bladder cancer, patients with continent cutaneous diversion of urine had fewer stoma-related problems than those with conduit diversion, but sexual dysfunction, disturbed partner relationships and emotional problems, which were common, did not differ between these groups. Psychological support was seldom provided by medical personnel. Despite the patients` high acceptance level of the malignancy, inability to accept their present condition was common. Prospective studies were performed to assess the influence of psychological defence mechanisms as evaluated with MCT-test and of mood, general philosophical outlook and type of urinary tract reconstruction on risk of psychosocial complications after cystectomy, and also the importance of early psychosocial intervention. Preoperative MCT-test had low value for predicting risk of such complications in patients studied 3 and 12 months postoperatively, but at 5 years "risk" patients expressed lower self-esteem and greater difficulties in interpersonal contact-seeking. Patients who postoperatively ascribed their life`s course to non-personal factors and who believed in a deity or a supernatural power tended to do poorly after surgery. With regard to method of reconstruction, patients with orthotopic bladder replacement adjusted less well. Psychosocial intervention did not influence emotional adaptation a 3-month follow-up, but was helpful in patients with continent cutaneous diversion. Defensive strategies and philosophical outlook did not by and large influence the outcome of intervention.

Tidskriftsartikel (refereegranskat)abstract
- The etiology of type 1 diabetes (T1D) remains unknown, but a growing body of evidence points to infectious agents and/or components of early childhood diet. The National Institutes of Health has established the TEDDY Study consortium of six clinical centers in the United States and Europe and a data coordinating center to identify environmental factors predisposing to, or protective against, islet autoimmunity and T1D. From 2004-2009, TEDDY will screen more than 360,000 newborns from both the general population and families already affected by T1D to identify an estimated 17,804 children with high-risk HLA-DR,DQ genotypes. Of those, 7,801 (788 first-degree relatives and 7,013 newborns with no family history of T1D) will be enrolled in prospective follow-up beginning before the age of 4.5 months. As of May 2008, TEDDY has screened more than 250,000 newborns and enrolled nearly 5,000 infants--approximately 70% of the final cohort. Participants are seen every 3 months up to 4 years of age, with subsequent visits every 6 months until the subject is 15 years of age. Blood samples are collected at each visit for detection of candidate infectious agents and nutritional biomarkers; monthly stool samples are collected for infectious agents. These samples are saved in a central repository. Primary endpoints include (1) appearance of one or more islet autoantibodies (to insulin, GAD65 or IA-2) confirmed at two consecutive visits; (2) development of T1D. By age 15, an estimated 800 children will develop islet autoimmunity and 400 will progress to T1D; 67 and 27 children have already reached these endpoints.

Staphylococcus epidermidis isolates from nares and prosthetic joint infections are mupirocin susceptible
- 2018
-
Ingår i: Journal of bone and joint infection. - : Ivyspring International Publisher. - 2206-3552. ; 3:1, s. 1-4
-
Tidskriftsartikel (refereegranskat)abstract
- The objective of the present study was to investigate the antibiotic susceptibility including mupirocin among Staphylococcus. epidermidis isolated from prosthetic joint infections (PJIs) (n=183) and nasal isolates (n=75) from patients intended to undergo prosthetic joint replacements. Susceptibility to mupirocin (used for eradication of nasal carriership of Staphylococcus aureus) was investigated by gradient test, and susceptibility to various other antimicrobial agents was investigated by disc diffusion test. All isolates, except three from PJIs and one from the nares, were fully susceptible to mupirocin. Multi-drug resistance (≥3 antibiotic classes) was found in 154/183 (84.2%) of the PJI isolates but only in 2/75 (2.7%) of the nares isolates, indicating that S. epidermidis causing PJIs do not originate from the nares.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND AND OBJECTIVES: Psychological symptoms can be associated with celiac disease; abstract however, this association has not been studied prospectively in a pediatric cohort. We examined mother report of psychological functioning in children persistently positive for tissue transglutaminase autoantibodies (tTGA), defined as celiac disease autoimmunity (CDA), compared with children without CDA in a screening population of genetically at-risk children. We also investigated differences in psychological symptoms based on mothers' awareness of their child's CDA status. METHODS: The Environmental Determinants of Diabetes in the Young study followed 8676 children to identify triggers of type 1 diabetes and celiac disease. Children were tested for tTGA beginning at 2 years of age. The Achenbach Child Behavior Checklist assessed child psychological functioning at 3.5 and 4.5 years of age. RESULTS: At 3.5 years, 66 mothers unaware their child had CDA reported more child anxiety and depression, aggressive behavior, and sleep problems than 3651 mothers of children without CDA (all Ps ≤ .03). Unaware-CDA mothers also reported more child anxiety and depression, withdrawn behavior, aggressive behavior, and sleep problems than 440 mothers aware of their child's CDA status (all Ps ≤.04). At 4.5 years, there were no differences. CONCLUSIONS: In 3.5-year-old children, CDA is associated with increased reports of child depression and anxiety, aggressive behavior, and sleep problems when mothers are unaware of their child's CDA status. Mothers' knowledge of their child's CDA status is associated with fewer reports of psychological symptoms, suggesting that awareness of the child's tTGA test results affects reporting of symptoms.

High cardiomyocyte diversity in human early prenatal heart development

Tidskriftsartikel (refereegranskat)abstract
- Cardiomyocytes play key roles during cardiogenesis, but have poorly understood features, especially in prenatal stages. Here, we characterized human prenatal cardiomyocytes, 6.5-7 weeks post-conception, by integrating single-cell RNA sequencing, spatial transcriptomics, and ligand-receptor interaction information. Using a computational workflow developed to dissect cell type heterogeneity, localize cell types, and explore their molecular interactions, we identified eight types of developing cardiomyocyte, more than double compared to the ones identified in the Human Developmental Cell Atlas. These have high variability in cell cycle activity, mitochondrial content, and connexin gene expression, and are differentially distributed in the ventricles, including outflow tract, and atria, including sinoatrial node. Moreover, cardiomyocyte ligand-receptor crosstalk is mainly with non-cardiomyocyte cell types, encompassing cardiogenesis-related pathways. Thus, early prenatal human cardiomyocytes are highly heterogeneous and develop unique location-dependent properties, with complex ligand-receptor crosstalk. Further elucidation of their developmental dynamics may give rise to new therapies.

Tidskriftsartikel (refereegranskat)abstract
- A total of 15 SNPs within complement genes and present on the ImmunoChip were analyzed in The Environmental Determinants of Diabetes in the Young (TEDDY) study. A total of 5474 subjects were followed from three months of age until islet autoimmunity (IA: n = 413) and the subsequent onset of type 1 diabetes (n = 115) for a median of 73 months (IQR 54-91). Three SNPs within ITGAM were nominally associated (p < 0.05) with IA: rs1143678 [Hazard ratio; HR 0.80; 95% CI 0.66-0.98; p = 0.032], rs1143683 [HR 0.80; 95% CI 0.65-0.98; p = 0.030] and rs4597342 [HR 1.16; 95% CI 1.01-1.32; p = 0.041]. When type 1 diabetes was the outcome, in DR3/4 subjects, there was nominal significance for two SNPs: rs17615 in CD21 [HR 1.52; 95% CI 1.05-2.20; p = 0.025] and rs4844573 in C4BPA [HR 0.63; 95% CI 0.43-0.92; p = 0.017]. Among DR4/4 subjects, rs2230199 in C3 was significantly associated [HR 3.20; 95% CI 1.75-5.85; p = 0.0002, uncorrected] a significance that withstood Bonferroni correction since it was less than 0.000833 (0.05/60) in the HLA-specific analyses. SNPs within the complement genes may contribute to IA, the first step to type 1 diabetes, with at least one SNP in C3 significantly associated with clinically diagnosed type 1 diabetes.

Tidskriftsartikel (refereegranskat)abstract
- As a magnetic resonance imaging (MRI) examination lasts about 45 minutes and as the technique is sensitive to motion, children are often given sedation or anesthesia. The aim of this study was to examine whether children aged three to nine years could undergo MRI while awake and achieve adequate image quality if age-adjusted routines were used. A two-group controlled experimental design was used. Thirty-six children were assigned to a control group and underwent MRI with the prevalent routines. Thirty-three children were assigned to an intervention group and underwent the MRI while awake. The age-adjusted routine included a booklet and a story book, a model of the MRI scanner with the MRI sound, and a DVD film during the examination. In the control group, 30 children underwent the examination under anesthesia and 6 underwent the examination while they were awake. All had acceptable examinations. In the intervention group, 33 children had their examination while awake and 30 of them had acceptable examinations. The parents' satisfaction with the care was assessed to be equal or higher in the intervention group and the costs were calculated to be lower. Thus, many children receiving age-appropriate preparation and distraction can undergo MRI examinations while awake.

Tidskriftsartikel (refereegranskat)abstract
- Purpose: To evaluate whether increased written information to patients prior to magnetic resonance imaging (MRI) decreases patient anxiety and image motion artifacts. Material and Methods: A two-group controlled experimental design was used. Of 242 patients, 118 received routinely given basic written information (control group) while 124 were given increased written information (intervention group). To measure patient anxiety before and during scanning, the self-report psychometric test State-Trait Anxiety Inventory (STAI) was used. After MR examination, the patients answered a questionnaire on satisfaction with the written information. The images were assessed with regard to motion artifacts. Results: Motion artifacts were present in fewer patient images in the intervention group than in the control group (4.0% versus 15.4%; P = 0.003). There was no significant difference between the control and the intervention group regarding patient anxiety and satisfaction with the information. Women in both groups showed a higher level of anxiety than the men did. Conclusion: Increased information about the MRI scanning procedure and expected experiences during the scan may help patients to lie still during the sequences, with a decrease in motion artifacts. However, further research is needed to evaluate the effect of other interventions on patient anxiety during MRI scanning.

- Aim. The aim of this study was to illuminate patients' lived experience during magnetic resonance imaging. Background. Magnetic resonance imaging has increased in importance since the early 1980s and is today a common useful diagnostic tool. Although magnetic resonance imaging are non-invasive and considered painless, many patients experience anxiety, sometimes so strong that the scan has to be terminated. Design and methods. The study had an inductive design and a hermeneutic phenomenological methodology was used. Results. The essential theme of going through magnetic resonance imaging was a feeling of being in another world. The strange environment and isolation inside the scanner made the participants' experiences unusual, with varying degrees of difficulty dealing with it. Being in the other world caused a threat to the participants' self-control. There was a relation between threat to self-control, effort and need for support in the sense that the magnitude of threat to self-control had an impact on the effort it took to handle the situation and on the need for support, and conversely that the support received could affect the effort and threat to self-control. Conclusions. The study shows that the information received and the interaction between patients and staff have a significant influence on patients' lived experiences. Relevance to clinical practice. The individual experience of threat to self-control requires the need for support to be individualized and care need to be adjusted for each patient.

Fibronectin binding by Propionibacterium acnes
- 1997

Ingår i: Pathogens and Disease. - 2049-632X. ; 19:3, s. 247-253
-
Tidskriftsartikel (refereegranskat)abstract
- Strains of Propionibacterium acnes, isolated from different kinds of orthopaedic and biomaterial-associated infections and from skin flora were shown to express binding of soluble as well as immobilized fibronectin. Among these 7 strains isolated from orthopaedic infections, 2 from breast prostheses, and 9 skin isolates, 2, 2, and 5 strains respectively bound immobilized fibronectin. The fibronectin binding was sensitive to protease and heat treatment, and was inhibited by a cell surface extract from one of the binding strains. In SDS-PAGE and autoradiography of cell surface extracts, a band corresponding to a MW of about 80 kD reacted with fibronectin and the 150 kD fragment of fibronectin. Binding to fibronectin and the 150 kD fragment of fibronectin could be inhibited with heparin. We thus present a first Fn binding protein of P. acnes, a surface exposed protein of 80 kD. None of the strains bound soluble collagen, and only one strain expressed weak binding of vitronectin and bone sialoprotein II.
