- BACKGROUND AND AIMS: Longstanding uncertainty surrounds the selection of surgical protocols for the closure of unilateral cleft lip and palate, and randomised trials have only rarely been performed. This paper is an introduction to three randomised trials of primary surgery for children born with complete unilateral cleft lip and palate (UCLP). It presents the protocol developed for the trials in CONSORT format, and describes the management structure that was developed to achieve the long-term engagement and commitment required to complete the project.METHOD: Ten established national or regional cleft centres participated. Lip and soft palate closure at 3-4 months, and hard palate closure at 12 months served as a common method in each trial. Trial 1 compared this with hard palate closure at 36 months. Trial 2 compared it with lip closure at 3-4 months and hard and soft palate closure at 12 months. Trial 3 compared it with lip and hard palate closure at 3-4 months and soft palate closure at 12 months. The primary outcomes were speech and dentofacial development, with a series of perioperative and longer-term secondary outcomes.RESULTS: Recruitment of 448 infants took place over a 9-year period, with 99.8% subsequent retention at 5 years.CONCLUSION: The series of reports that follow this introductory paper include comparisons at age 5 of surgical outcomes, speech outcomes, measures of dentofacial development and appearance, and parental satisfaction. The outcomes recorded and the numbers analysed for each outcome and time point are described in the series.TRIAL REGISTRATION: ISRCTN29932826.

Data-driven analysis of a validated risk score for ovarian cancer identifies clinically distinct patterns during follow-up and treatment
- 2022

Tidskriftsartikel (refereegranskat)abstract
- BackgroundOvarian cancer is the eighth most common cancer among women and due to late detection prognosis is poor with an overall 5-year survival of 30–50%. Novel biomarkers are needed to reduce diagnostic surgery and enable detection of early-stage cancer by population screening. We have previously developed a risk score based on an 11-biomarker plasma protein assay to distinguish benign tumors (cysts) from malignant ovarian cancer in women with adnexal ovarian mass.MethodsProtein concentrations of 11 proteins were characterized in plasma from 1120 clinical samples with a custom version of the proximity extension assay. The performance of the assay was evaluated in terms of prediction accuracy based on receiver operating characteristics (ROC) and multiple hypothesis adjusted Fisher’s Exact tests on achieved sensitivity and specificity.ResultsThe assay’s performance is validated in two independent clinical cohorts with a sensitivity of 0.83/0.91 and specificity of 0.88/0.92. We also show that the risk score follows the clinical development and is reduced upon treatment, and increased with relapse and cancer progression. Data-driven modeling of the risk score patterns during a 2-year follow-up after diagnosis identifies four separate risk score trajectories linked to clinical development and survival. A Cox proportional hazard regression analysis of 5-year survival shows that at time of diagnosis the risk score is the second-strongest predictive variable for survival after tumor stage, whereas MUCIN-16 (CA-125) alone is not significantly predictive.ConclusionThe robust performance of the biomarker assay across clinical cohorts and the correlation with clinical development indicates its usefulness both in the diagnostic work-up of women with adnexal ovarian mass and for predicting their clinical course.

Periodontal Health and Oral Microbiota in Patients with Rheumatoid Arthritis
- 2019
-
Ingår i: Journal of Clinical Medicine. - : MDPI AG. - 2077-0383. ; 8:5
-
Tidskriftsartikel (refereegranskat)abstract
- This study aimed to investigate the periodontal health of patients with established rheumatoid arthritis (RA) in relation to oral microbiota, systemic and oral inflammatory mediators, and RA disease activity. Forty patients underwent full-mouth dental/periodontal and rheumatological examination, including collection of blood, saliva, gingival crevicular fluid (GCF) and subgingival plaque. Composition of plaque and saliva microbiota were analysed using 16S rRNA sequencing and levels of inflammatory mediators by multiplex-immunoassay. The majority of the patients (75%) had moderate or severe periodontitis and the rest had no/mild periodontitis. Anti-citrullinated protein antibody (ACPA) positivity was significantly more frequent in the moderate/severe periodontitis (86%) compared to the no/mild group (50%). No significance between groups was observed for RA disease duration or activity, or type of medication. Levels of sCD30/TNFRSF8, IFN-2, IL-19, IL-26, MMP-1, gp130/sIL-6R ss, and sTNF-R1 were significantly higher in serum or GCF, and April/TNFSF13 was significantly higher in serum and saliva samples in moderate/severe periodontitis. The microbial composition in plaque also differed significantly between the two groups. In conclusion, the majority of RA patients had moderate/severe periodontitis and that this severe form of the disease was significantly associated with ACPA positivity, an altered subgingival microbial profile, and increased levels of systemic and oral inflammatory mediators.

Essentials of Nursing Care in Randomized Controlled Trials of Nurse-Led Interventions in Somatic Care : A Systematic Review
- 2014
-
Ingår i: Open Journal of Nursing. - Irvine : Scientific Research Publishing. - 2162-5336 .- 2162-5344. ; 4:3, s. 181-197
-
Forskningsöversikt (refereegranskat)abstract
- Background: Nursing practice has to contribute to evidence pointing out why there is a need for more nurse-designed randomized control trials (RCTs) focusing on evidence-based practice (EBP). How far this EBP has progressed in different health aspects is usually established by systematic reviews of RCTs. Nurse-led RCTs exist but no study has addressed the essentials of nursing care. Aim: The aim was therefore to determine the essentials of nurses’ interventions by means of nurse-led RCTs in somatic care focusing on the stated context, goals, content, strategies as well as the nurse’s role related to effectiveness. Methods: A systematic review was realized according to Cochrane review assumptions to identify, appraise and synthesize all empirical evidence meeting pre-specified eligibility criteria. The PRISMA statement guided the data extraction process (n = 55) from PubMed and CINAHL. Results: Of the RCTs in somatic care, 71% showed a positive effectiveness of nurse-led interventions, of which the nurse had a significant role with regard to being the main responsible in 67% of the studies. Also, 47% of the RCTs presented a theoretical standpoint related to the nurse-led interventions and most prominent were international evidence-based guidelines. Goals were found to have either a patient-centered or a professional-centered ambition. Strategies were based on patient-directed initiatives, nurse-patient-directed initiatives or nurse-directed initiatives, while contents were built upon either a patient-nurse interaction or a nursing management plan. Conclusions: This review underlines the necessity of a holistic view of a person, as nurse-led RCTs comprising a patient-centered ambition, patient-directed initiative and patient-nurse interaction plan showed beneficial nursing care effectiveness, particularly if theory-based. In a nurse-led RCT, a basic theoretical perspective is advantageous as well as to elucidate the role of the nurse in relation to the estimated effects.

Toward ovarian cancer screening with protein biomarkers using dried, self-sampled cervico-vaginal fluid
- 2024
-
Ingår i: iScience. - : Cell Press. - 2589-0042. ; 27:2
-
Tidskriftsartikel (refereegranskat)abstract
- Early detection is key for increased survival in ovarian cancer, but no general screening program exists today due to lack of biomarkers and overall cost versus benefit over traditional clinical methods. Here, we used dried cervico-vaginal fluid (CVF) as sampling matrix coupled with mass spectrometry for detection of protein biomarkers. We find that self-collected CVF on paper cards yields robust results and is suitable for high-throughput proteomics. Artificial intelligence–based methods were used to identify an 11-protein panel that separates cases from controls. In validation data, the panel achieved a sensitivity of 0.97 (95% CI 0.91–1.00) at a specificity of 0.67 (0.40–0.87). Analyses of samples collected prior to development of symptoms indicate that the panel is informative also of future risk of disease. Dried CVF is used in cervical cancer screening, and our results opens the possibility for a screening program also for ovarian cancer, based on self-collected CVF samples.

An immune score reflecting pro- and anti-tumoural balance of tumour microenvironment has major prognostic impact and predicts immunotherapy response in solid cancers
- 2023
-
Ingår i: EBioMedicine. - : Elsevier. - 2352-3964. ; 88
-
Tidskriftsartikel (refereegranskat)abstract
- Background: Cancer immunity is based on the interaction of a multitude of cells in the spatial context of the tumour tissue. Clinically relevant immune signatures are therefore anticipated to fundamentally improve the accuracy in predicting disease progression.Methods: Through a multiplex in situ analysis we evaluated 15 immune cell classes in 1481 tumour samples. Single-cell and bulk RNAseq data sets were used for functional analysis and validation of prognostic and predictive associations.Findings: By combining the prognostic information of anti-tumoural CD8+ lymphocytes and tumour supportive CD68+CD163+ macrophages in colorectal cancer we generated a signature of immune activation (SIA). The prognostic impact of SIA was independent of conventional parameters and comparable with the state-of-art immune score. The SIA was also associated with patient survival in oesophageal adenocarcinoma, bladder cancer, lung adenocarcinoma and melanoma, but not in endometrial, ovarian and squamous cell lung carcinoma. We identified CD68+CD163+ macrophages as the major producers of complement C1q, which could serve as a surrogate marker of this macrophage subset. Consequently, the RNA-based version of SIA (ratio of CD8A to C1QA) was predictive for survival in independent RNAseq data sets from these six cancer types. Finally, the CD8A/C1QA mRNA ratio was also predictive for the response to checkpoint inhibitor therapy.Interpretation: Our findings extend current concepts to procure prognostic information from the tumour immune microenvironment and provide an immune activation signature with high clinical potential in common human cancer types.

Tidskriftsartikel (refereegranskat)abstract
- A first research development progress report of the Chromosome 19 Consortium with members from Sweden, Norway, Spain, United States, China and India, a part of the Chromosome-centric Human Proteome Project (C-HPP) global initiative, is presented (http://www.c-hpp.org). From the chromosome 19 peptide-targeted library constituting 6159 peptides, a pilot study was conducted using a subset with 125 isotope-labeled peptides. We applied an annotation strategy with triple quadrupole, ESI-Qtrap, and MALDI mass spectrometry platforms, comparing the quality of data within and in between these instrumental set-ups. LC–MS conditions were outlined by multiplex assay developments, followed by MRM assay developments. SRM was applied to biobank samples, quantifying kallikrein 3 (prostate specific antigen) in plasma from prostate cancer patients. The antibody production has been initiated for more than 1200 genes from the entire chromosome 19, and the progress developments are presented. We developed a dedicated transcript microarray to serve as the mRNA identifier by screening cancer cell lines. NAPPA protein arrays were built to align with the transcript data with the Chromosome 19 NAPPA chip, dedicated to 90 proteins, as the first development delivery. We have introduced an IT-infrastructure utilizing a LIMS system that serves as the key interface for the research teams to share and explore data generated within the project. The cross-site data repository will form the basis for sample processing, including biological samples as well as patient samples from national Biobanks.

Tidskriftsartikel (refereegranskat)abstract
- Salvadora persica is commonly used chewing sticks in many parts of the world as an oral hygiene tool. This study measured the amount of benzyl isothiocyanate (BITC) released into the mouth and assessed its retention time in saliva. The study also tested if the released amount of BITC could potentially be antibacterial or cytotoxic. Twelve subjects brushed their teeth with fresh Miswak once, twice, and four times. The amount of BITC in the saliva and in the used brushes was quantified using gas chromatography-mass spectrometry. The antibacterial effect of BITC and Miswak essential oil (MEO) was tested against Haemophilus influenzae, Aggregatibacter actinomycetemcomitans, and Porphyromonas gingivalis. The cytotoxic effect on gingival fibroblasts and keratinocytes was tested using MTT. The highest amount of the active compounds was detected in saliva after using the Miswak tip for once and immediately. It significantly decreased when the Miswak tip was used more than once and thus after 10 min. The growth of the tested bacteria was inhibited by MEO and BITC in a dose dependent manner, P. gingivalis being the most sensitive. MTT assay showed that BITC and MEO were cytotoxic towards gingival fibroblasts while oral keratinocytes showed resistance. This study suggests that the Miswak tip should be cut before each use to ensure the maximum effect.

Incentives behind and Experiences of Being Active in Working Life after Age 65 in Sweden
- 2022
-
Ingår i: International Journal of Environmental Research and Public Health. - : MDPI AG. - 1661-7827 .- 1660-4601. ; 19:23
-
Tidskriftsartikel (refereegranskat)abstract
- Since individual and societal expectations regarding the possibility of an extended working life after the expected retirement age are increasing, research on sustainable working life combined with healthy ageing is needed. This study explores the incentives behind and experiences of an extended working life after the expected retirement age of 65 among Swedish people. The inductive qualitative content analyses are based on 18 individual semi-structured interviews among persons 67–90 years old with varying characteristics and varying experiences of extended working lives. The analyses revealed that working contributed to (1) sustained internal resources, i.e., cognitive function, physical ability and increased vigor; (2) sustained external resources, i.e., social enrichment, better daily routines and economic benefits; (3) added meaningfulness to life, i.e., being needed, capability and satisfaction with working tasks. Meanwhile, having flexible working conditions enabled a satisfying balance between work and leisure. Altogether, these different aspects of overall health and working life were interpreted as contributing to increased feelings of vitality, the innermost dimension of health. Conclusions: regardless of biological age, our results indicate that being able to remain active in working life can be beneficial to vitality and could make these results valuable for both health-care personnel and employers.

Pyriproxifen and microcephaly: an investigation of potential ties to the ongoing "Zika epidemic"
- 2016
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- As part of the Swetox mission to react to emerging concerns in chemical health and environmental safety, a preliminary litterature investigation was undertaken to gather all readily available scientific information on PPF with respect to safety assessment, in order to better understand potential links between chemical exposure and the devopment of microcephaly in affected areas. Therefore the contents of the report do not constitute an attempt at either questioning the use of existing regulatory data in the manner prescribed by international regulatory proceedures, or as a new risk assessment, based on the scientific information and concepts discussed. Here we report our findings, with particular emphasis on exisiting regulatory information, potential for lack of translation of results from regulatory animal testing to humans, lack of human exposure data and suggestions on plausible mode(s) of action of PPF in human neurodevelopmental adversities such as microcephaly.

Mass balance study of brominated flame retardants in female captive peregrine falcons
- 2019
-
Ingår i: Environmental Science-Processes & Impacts. - : Royal Society of Chemistry (RSC). - 2050-7887 .- 2050-7895. ; 21:7, s. 1115-1131

Tidskriftsartikel (refereegranskat)abstract
- Little is known about brominated flame retardant (BFR) dynamics in birds, especially large molecules such as decabromodiphenyl ether (BDE-209). In particular, bioaccumulation from food and transfer dynamics to eggs are poorly understood. Therefore, an input-output mass balance study of tri-decaBDEs, DBDPE and HBCDD was performed in three female peregrine falcons from a captive breeding program by analyzing their naturally contaminated food (quail, chicken (cockerels)), plasma, feces and eggs. Predominant BFRs in cockerels and quail were BDE-209 and DBDPE, as well as HBCDD in quail. The predominant BFRs found in falcon plasma were BDE-209, -153 and -183, in eggs, HBCDD, BDE-209 and -153 and in feces, BDE-209. Mean absorption efficiencies (AE) for the tetra-octabrominated BDEs ranged from 84-100% and 70% for HBCDD. The AEs for BDE-206, -207, -208 and -209 varied due to the large variability seen for feces fluxes. All egg/plasma ratios for BDEs were similar and greater than one (range 1.1-2.7), including for BDE-209, indicating efficient transfer from females to the eggs. Excretion via egg-laying was approximately 6.0-29% of the initial, pre-breeding body burden of individual penta-decaBDE congeners, (15-45% for BDE-206). HBCDD was not detected in plasma but was found in eggs, also indicating efficient transfer and excretion via eggs. Input fluxes from food exceeded the output fluxes (feces, eggs) indicating considerable metabolism for tetra-octaBDEs, possibly also for the nona-decaBDEs and HBCDD. Bioaccumulation factors calculated from lipid weight concentrations in plasma and food (BAF(p)) were highest for BDE-208 (31), -153 (23), -209 (19) and -207 (16) and from eggs and food (BAF(e)), were highest for HBCDD (140), BDE-153 (41), -208 (42), BDE-207 (24) and BDE-209 (21). BAF(e) and BAF(p) values were below 10 for BDE-47, -99 and -100. For one falcon, egg results were available from three different years and estimated half-lives were 65 d (BDE-99), 624 d (BDE-153), 31 d (BDE-154), 349 d (BDE-183), 77 d (BDE-196) and 89 d (BDE-197).

Tidskriftsartikel (refereegranskat)abstract
- Background And Objectives: Early obesity treatment seems to be the most effective, but few treatments exist. In this study, we examine the effectiveness of a parent-only treatment program with and without booster sessions (Booster or No Booster) focusing on parenting practices and standard treatment (ST).Methods: Families of children 4 to 6 years of age with obesity were recruited from 68 child care centers in Stockholm County and randomly assigned to a parent-only program (10 weeks) with or without boosters (9 months) or to ST. Treatment effects on primary outcomes (BMI z score) and secondary outcomes (BMI and waist circumference) during a 12-month period were examined with linear mixed models. The influence of sociodemographic factors was examined by 3-way interactions. The clinically significant change in BMI z score (−0.5) was assessed with risk ratios.Results: A total of 174 children (mean age: 5.3 years [SD = 0.8]; BMI z score: 3.0 [SD = 0.6], 56% girls) and their parents (60% foreign background; 39% university degree) were included in the analysis (Booster, n = 44; No Booster, n = 43; ST, n = 87). After 12 months, children in the parent-only treatment had a greater reduction in their BMI z score (0.30; 95% confidence interval [CI]: −0.45 to −0.15) compared with ST (0.07; 95% CI: −0.19 to 0.05). Comparing all 3 groups, improvements in weight status were only seen for the Booster group (−0.54; 95% CI: −0.77 to −0.30). The Booster group was 4.8 times (95% CI: 2.4 to 9.6) more likely to reach a clinically significant reduction of ≥0.5 of the BMI z score compared with ST.Conclusion: A parent-only treatment with boosters outperformed standard care for obesity in preschoolers.

Associations between Parental Concerns about Preschoolers' Weight and Eating and Parental Feeding Practices : Results from Analyses of the Child Eating Behavior Questionnaire, the Child Feeding Questionnaire, and the Lifestyle Behavior Checklist
- 2016

Tidskriftsartikel (refereegranskat)abstract
- INTRODUCTION: Insight into parents' perceptions of their children's eating behaviors is crucial for the development of successful childhood obesity programs. However, links between children's eating behaviors and parental feeding practices and concerns have yet to be established. This study aims to examine associations between parental perceptions of preschoolers' eating behaviors and parental feeding practices. First, it tests the original 8-factor structure of the Child Eating Behavior Questionnaire (CEBQ). Second, it examines the associations with parental feeding practices, measured with the Child Feeding Questionnaire (CFQ).MATERIALS AND METHODS: Questionnaires were sent to parents from 25 schools/preschools in Stockholm, Sweden and to parents starting a childhood obesity intervention. The CEBQ factor structure was tested with confirmatory factor analysis (CFA). Associations between CEBQ subscales Food approach and Food avoidance and CFQ factors Restriction, Pressure to eat and Monitoring were examined with structural equation modelling (SEM), adjusting for child and parental characteristics, and parental confidence, measured with the Lifestyle Behavior Checklist (LBC). CFQ Concern for child weight and Perceived responsibility for child eating were used as mediators.RESULTS: 478 parents completed the questionnaires (children: 52% girls, mean age 5.5 years, 20% overweight/obese). A modified 8-factor structure showed an acceptable fit (TLI = 0.91, CFI = 0.92, RMSEA = 0.05 and SRMR = 0.06) after dropping one item and allowing three pairs of error terms to correlate. The SEM model demonstrated that Food approach had a weak direct effect on Restriction, but a moderate (β = 0.30) indirect effect via Concern, resulting in a substantial total effect (β = 0.37). Food avoidance had a strong positive effect on Pressure to eat (β = 0.71).DISCUSSION: The CEBQ is a valid instrument for assessing parental perceptions of preschoolers' eating behaviors. Parental pressure to eat was strongly associated with children's food avoidance. Parental restriction, however, was more strongly associated with parents' concerns about their children's weights than with children's food approach. This suggests that childhood obesity interventions should address parents' perceptions of healthy weight alongside perceptions of healthy eating.

- Aim: To present a model for associations between preschoolers’ eating behaviors (measured with the Child Eating Behavior Questionnaire, CEBQ), and parental feeding practices (measured with the Child Feeding Questionnaire, CFQ).Methods: First, the original 8-factor structure of CEBQ was tested with Confirmatory factor analysis (CFA). Second, the associations between the two CEBQ dimensions of child eating (Food approach and Food avoidance) and the key CFQ parental feeding practices (Restriction and Pressure to eat) were examined with structural equation modelling (SEM). CFQ Concern for child weight and CFQ Perceived responsibility for child eating were used as mediators.Results: In a sample of 478 parents (81 % mothers, 87% of Nordic origin, 70 % with university degree) of children from Stockholm County (52 % girls, mean age 5.5 years, 20 % overweight/obese) the CFA demonstrated an acceptable fit (TLI=0.91, CFI=0.92, RMSEA=0.05) for a modified 8-factor structure. The SEM model, adjusted for child and parental characteristics, demonstrated that Food approach had a weak direct effect on Restriction, however, it had quite a strong (β: 0.30) indirect effect via concern, which resulted in a substantial total effect (β: 0.37). Further, there was a strong positive direct effect of Food avoidance on Pressure to eat (β: 0.71; p<0.001).Conclusion: The CEBQ proved to be a valid instrument for assessing parental perceptions of preschoolers’ eating behaviors. Parental controling behaviour towards children with big appetites was especially pronounced when parents were concerned for child weight, implying that parental cognitions shouldn’t be forgotten when designing obesity interventions.

- Malaria infection renders humans more attractive to Anopheles gambiae sensu lato mosquitoes than uninfected people. The mechanisms remain unknown. We found that an isoprenoid precursor produced by Plasmodium falciparum, (E)-4-hydroxy-3-methyl-but-2-enyl pyrophosphate (HMBPP), affects A. gambiae s. l. blood meal seeking and feeding behaviors as well as susceptibility to infection. HMBPP acts indirectly by triggering human red blood cells to increase the release of CO2, aldehydes, and monoterpenes, which together enhance vector attraction and stimulate vector feeding. When offered in a blood meal, HMBPP modulates neural, antimalarial, and oogenic gene transcription without affecting mosquito survival or fecundity; in a P. falciparum-infected blood meal, sporogony is increased.

Tidskriftsartikel (refereegranskat)abstract
- Despite availability of annual influenza vaccines, influenza causes significant morbidity and mortality in the elderly. This is at least in part a result of immunosenescence; the age-dependent decrease in immunological competence that results in greater susceptibility to infections and reduced responses to vaccination. To improve protective immune responses in this age group, new vaccines strategies, such as the use of adjuvants, are needed. Here, we evaluated the mucosal vaccine adjuvant Endocine(TM), formulated with split influenza antigen and administered intranasally in aged (20-month old) mice. Humoral immune responses were assessed and compared to unadjuvanted intranasal and subcutaneous vaccines. We show that formulation with Endocine(TM) significantly enhances hemagglutination inhibition (HI) titers, as well as serum IgG and mucosal IgA antibody titers, compared to both types of unadjuvanted vaccines. Thus, our results indicate that intranasal vaccination with Endocine(TM) is a possible approach for the development of mucosal influenza vaccines for the elderly.

The mucosal adjuvant 1 Endocine™ increases immune responses to influenza antigen in aged mice
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- More effective influenza vaccines for the elderly population is needed. The vaccines used today are less effective in elderly compared to in adults. It is more difficult to stimulate a protective immune response in elderly due to immunosenescence. Elderly people have a decline in both humoral and cell mediated immunity, which make them more susceptible to viral infections. The aim of this study was to evaluate the mucosal adjuvant Endocine™ together with split influenza antigen in different ages of BALB/c mice (15, 20 and 25 months old). The results from this study show that a nasal influenza vaccine formulated with Endocine™ enhanced both systemic and mucosal immune responses compared to an unadjuvanted vaccine delivered subcutaneously or intra nasal in aged mice. However, in the 25 months old mice only a very modest immune response was detected. Although the influenza-specific immune responses in aged mice were not induced to the same levels as achieved in young mice, the results show that nasal vaccine formulated with Endocine™ could provide benefits for the elderly.

Tidskriftsartikel (refereegranskat)abstract
- The expression of tlr4, md2 and cd14 was studied in equine blood leukocytes and in intestinal samples using real time PCR. The stability of three commonly used reference genes, glyceraldehyde-3P-dehydrogenase (GAPDH), hypoxantine ribosyltransferase (HPRT) and succinate dehydrogenase complex subunit A (SDHA), was evaluated using qbase(PLUS). The equine peripheral blood mononuclear cells (eqPBMC) examined were either stimulated in vitro with Phorbol 12-myristate 13-acetate (PMA) and ionomycin or with the CpG oligodeoxynuclotide 2216 (CpG-ODN 2216) or obtained from horses before, during and after infusion of endotoxin. Intestinal tissue from healthy horses was sampled at ileum, right dorsal colon and rectum. Ranking of the three reference genes used for normalisation identified the combination HPRT/SDHA as most suitable both when determined ex vivo in leukocytes obtained from experimentally induced endotoxaemia and in eqPBMC activated in vitro while HPRT/GAPDH were most appropriate for the intestinal samples. The relative amounts of mRNA for TLR4 and MD-2 increased threefold during in vitro activation of the cells with CpG-ODN 2216 but was decreased in cultures stimulated with PMA/ionomycin. A transient elevation in the transcription of tlr4 and md2 was also evident for equine blood leukocytes following endotoxaemia. The levels of mRNA for CD14 on the other hard remained unaffected both during the induction of endotoxaemia and in the in vitro stimulated PBMCs. A low steady expression of TLR4, MD-2 and CD14 mRNA was demonstrated for the intestinal samples with no variation between the intestinal segments analysed. Thus, the foundation for real time PCR based levels of analysis of mRNA for all three components in the equine LPS receptor complex in different intestinal segments was set, making it possible to carry out future expression studies on clinical material.

Forskningsöversikt (refereegranskat)abstract
- Background: Teamcare should, like all patient care, also contribute to evidence-based practice (EBP). Randomized controlled trials (RCTs) focusing on teamcare have been performed but no study has addressed its essentials. How far this EBP has progressed in different health aspects is generally established in systematic reviews of RCTs.Aim: The aim is to determine the essentials of teamcare including the nurse profession in RCTs of multi- or interdisciplinary interventions in somatic care focusing on the stated context, goals, strategies, content as well as effectiveness of quality of care.Methods: A systematic review was performed according to Cochrane review assumptions to identify, appraise and synthesize all empirical evidence meeting pre-specified eligibility criteria. The PRISMA statement guided the data selection process of 27 articles from PubMed and CINAHL.Results: Eighty-five percent of RCTs in somatic care showed a positive effectiveness of teamcare interventions, of which interdisciplinary ones showed a greater effectiveness compared with the multidisciplinary approach (100% vs 76%). Also theory-based RCTs presented higher positive effectiveness (85%) compared with non-theory-based RCTs (79%). The RCTs with positive effectiveness showed greater levels for professional-centered ambition in terms of goals and for team-directed initiatives in terms of strategy, and a significantly higher level for patient-team interaction plans in terms of content was shown.Conclusions: Teamcare RCTs are still grounded in the multidisciplinary approach having a professional-centered ambition while interdisciplinary approaches especially those that are theory-based appear to be essential with regard to positive effectiveness and preferable when person-centered careis applied.

- Perfluorinated alkyl substances (PFAS) are today known to beglobally distributed environmental contaminants. In the present study, concentrations of PFAS were analyzed in Swedish peregrine falcon eggs (Falco peregrinus), collected between 1974and2007.Analytesincludedinthestudywereperfluorinated carboxylates (PFCAs; carbon chain lengths C6-C15), perfluorinated sulfonates (PFSAs; C4, C6, C8, and C10), and perfluorooctane sulfonamide (PFOSA). The predominant PFAS was perfluorooctane sulfonate, PFOS (83 ng/g wet weight (w wt) mean concentration in samples from 2006), followed by perfluorotridecanoate, PFTriA (7.2 ng/g w wt) and perfluoroundecanoate, PFUnA (4.2 ng/g w wt). PFCA concentrations increased exponentially over the studied time. In contrast, concentrations of PFOS and perfluorohexane sulfonate (PFHxS) increased initially but leveled off after the mid 1980s. This is different from previously observed temporal trends in marine organisms. The present study is the first to establish temporal trends for PFAS in terrestrial biota. The results indicate potential differences between marine and terrestrial biota regarding sources of PFAS exposure and response to emission changes. The toxicological implications of PFAS exposure for the falcons are not known, but according to recent findings impaired hatching success and sublethal toxicological effects from PFOS exposure in the Swedish peregrine falcon cannot be ruled out.

Tidskriftsartikel (refereegranskat)abstract
- Previous analyses of 52 peregrine falcon (Falco peregrinus) eggs collected from two wild and one captive population in Sweden 1987 through 1999 were complemented by including additional polybrominated diphenyl ether (PBDE) congeners (BDE-35, -183, -184, -185, -196, -197, -203, and -207). In addition, 31 eggs not previously analyzed for hexabromocyclododecane (HBCD) and BDE-209 were analyzed for these. Geometric mean concentrations of BPBDEs, HBCD, and the hexabrominated biphenyl (BB-153) were 3,100, 140, and 81 ng/g of lipid weight for the southern population; 2,500, 110, and 84 ng/g of lipid weight for the northern population; and 47, not detected, and 8 ng/g of lipid weight for the captive population. The BDE congener pattern was dominated by BDE-153, -99, and -100. The results were used to investigate whether a difference in PBDE congener pattern could be distinguished between the two wild populations of peregrine falcons due to different diets, as the southern population preys mainly on birds belonging to the terrestrial food chain while the northern population preys more on aquatic birds. A multivariate t-test showed a subtle but significant (p < 0.001) difference in PBDE congener pattern between the two populations. However, our hypothesis that higher-brominated congeners of PBDEs would be present to a greater extent in the terrestrial food chain was not supported by principal component analysis. The average brood size for individual females from the southern population decreased with increasing concentrations of IPBDE in the eggs (log-linear regression p < 0.01).

Tidskriftsartikel (refereegranskat)abstract
- Recombination is an important feature in theevolution of the Enterovirus genus. Phylogenetic studies ofenteroviruses have revealed that the capsid genomic region(P1) is type specific, while the parts of the genome codingfor the non-structural proteins (P2–P3) are species specific.Hence, the genome may be regarded as consisting of twomodules that evolve independently. In this study, it wasinvestigated whether the non-structural coding part of thegenome in one type could support replication of a virus witha P1 region from another type of the same species. A cas-sette vector (pCas) containing a full-length cDNA copy ofcoxsackievirus B5 (CVB5) was used as a replicative back-bone. The P1 region of pCas was replaced with the corre-sponding part from coxsackievirus B3Nancy(CVB3N),coxsackievirus B6Schmitt(CVB6S), and echovirus 7Wal-lace(E7W), all members of theEnterovirus Bspecies. Thereplication efficiency after transfection with clone-derivedin vitro transcribed RNA was studied and compared withthat of pCas. All the recombinant viruses replicated with similar efficiencies and showed threshold cycle (Ct) values,tissue culture infectivity dose 50 %, and plaque-forming unittiters comparable to viruses generated from the pCas con-struct. In addition to this, a clone without the P1 region wasalso constructed, and Western Blot and immunofluorescencestaining analysis showed that the viral genome could betranslated and replicated despite the lack of the structuralprotein-coding region. To conclude, the replicative back-bone of the CVB5 cassette vector supports replication ofintraspecies constructs with P1 regions derived from othermembers of theEnterovirus Bspecies. In addition to this,the replicative backbone can be both translated and repli-cated without the presence of a P1 region.

Tidskriftsartikel (refereegranskat)abstract
- Extensive angiogenesis, formation of new capillaries from pre-existing blood vessels, is an important feature of malignant glioma. Several antiangiogenic drugs targeting vascular endothelial growth factor (VEGF) or its receptors are currently in clinical trials as therapy for high-grade glioma and bevacizumab was recently approved by the FDA for treatment of recurrent glioblastoma. However, the modest efficacy of these drugs and emerging problems with anti-VEGF treatment resistance welcome the development of alternative antiangiogenic therapies. One potential candidate is histidine-rich glycoprotein (HRG), a plasma protein with antiangiogenic properties that can inhibit endothelial cell adhesion and migration. We have used the RCAS/TV-A mouse model for gliomas to investigate the effect of HRG on brain tumor development. Tumors were induced with platelet-derived growth factor-B (PDGF-B), in the presence or absence of HRG. We found that HRG had little effect on tumor incidence but could significantly inhibit the development of malignant glioma and completely prevent the occurrence of grade IV tumors (glioblastoma).

Accident prevention through experience feedback from the rescue services : A study of incident reports in Sweden
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- The fire and rescue services are called to the scene of almost all serious accidents. The purpose of this investigation was to find out whether the information they obtain in the course of their normal operations can be used to improve experience feedback in sectors where it is at present weak or non-existent. 1120 incident reports from two local Swedish fire and rescue services were studied. These reports contained 217 proposals for improvement. However, the reports are primarily intended for statistical purposes, and they are currently not used for experience feedback. A system for dissemination of such information is proposed. It is suggested that the rescue services are best equipped to transmit the relevant information to local recipients. A national authority can be entrusted with task to the review and collate information intended for non-local recipients such as companies whose products have been involved in accident and regulatory authorities whose safety regulations may need to be reassessed in light of the experiences reported.

Att lära av inspektörers erfarenheter : En undersökning av inspektionsverksamheten i elva kommuner
- 2006
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Med syfte att undersöka hur erfarenheter från tillsynsärenden tas om hand inom kommunal miljötillsyn samt att se över hur tillsynsarbetet fungerar har 28 tillsynsärenden från elva kommuner studerats. Vid urvalet av kommuner har viss hänsyn tagits till Sveriges Kommuner och Landstings kommungruppering samt till kommunernas geografiska läge. De elva utvalda kommunernas miljökontor har kontaktats och ombetts välja ut exempel på tillsynsärenden med allvarliga missförhållanden och andra intressanta ärenden. Varje ärende har sammanfattats med hjälp av dokumentation som kommunerna har försett oss med. Intervjuer har också genomförts med någon i varje ärende insatt person. Samtal har även förts med andra inblandade.Genomgången av ärendena har visat på att en viktig fråga för inspektörerna när det gäller erfarenhetsåterföring är de juridiska spörsmålen. Det har bland annat framförts att inspektörerna vill ha mer återkoppling från rättsväsendet. Miljönämnderna är enligt 26 kap. 2 § miljöbalken skyldiga att anmäla överträdelser av balken. Åklagarna lägger ofta ner förundersökningar i miljöärenden utan att miljökontoren får någon förklaring till varför. Inspektörerna vill också bli informerade om vad som händer med utdömda viten.En viktig aspekt som undersökningen har påvisat när det gäller erfarenhetsåterföring är betydelsen av fungerande samarbeten. De samarbetsformer som främst nämns av inspektörerna är de regionala. Centrala myndigheters betydelse förefaller bli allt mindre. Det har även framkommit exempel på områden där ytterligare erfarenhetsåterföring är att önska.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- This paper examines the activities of the Swedish Work Environment Authority's Accident Investigation Board. It first gives an outline of the board's role and a summary of the previous literature on accident investigation. It then proposes an investigation methodology, the CHAIN model, which forms the theoretical point of departure of the paper. It describes the methods used in the empirical study, and examines the board's investigation criteria and how these were implemented. A summary of the effects of the board's reports on affected companies is presented, along with a survey of SWEA inspectors and interviews with workplace inspectors and others who have an interest in workplace accident investigation. Finally, the study's results are compared to the CHAIN model, with the conclusions that: • the board has been successful in establishing a high qualitative standard for investigating workplace accidents • the investigation process should be speeded up if the board's reports are to realise their full potential • dissemination of the reports must be improved, and a follow-up system is needed.

Experience feedback in practice
- 2008
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The subject of this licentiate thesis is experience feedback from accidents and incidents. The thesis aims to contribute to an understanding of how the learning processes within organizations, companies and authorities could be improved. Essay I (written together with Sven Ove Hansson) reports on an evaluation carried out in 2004 by the Swedish Work Environment Authority’s Accident Investigation Board, called HAKO (Haverikommissionen). An important outcome of this evaluation shows that HAKO have not been able to manage the dissemination of their written reports, which is unfortunate, since the reports are thoroughly written. Essay II (written with Sven Ove Hansson and Carl Rollenhagen) is an overview of the literature on learning from accidents and incidents. The focus in this essay is on literature that evaluates the effectiveness and usefulness of different methods in accident investigations. The conclusions drawn from this literature review are that the dissemination of results and knowledge from accident investigations must be improved, and experience feedback systems should be integrated into overall systems of risk management. The starting point for Essay III was an empirical study conducted in 2005/2006. Twenty-eight supervision cases from eleven local Environment and Health Administrations in Sweden were examined. The overall goal of the study was to find out how, and to what extent, experience feedback occurs between different municipal authorities. Two major problems affecting experience feedback have been found; namely, that the inspectors do not have enough guidance on how to interpret the law, and that they would like more information on what happens to legal cases they have reported to public prosecutors and police.

Investigating experience feedback in Swedish authorities : An empirical study of experience feedback practice in 21 Swedish authorities
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- This article focuses on practical experience feedback. Results from two interview studies are reported. In the first, experience feedback in different sectors in Sweden was investigated through interviews with 21 Swedish authorities involved in accident prevention. A result from this investigation was that the participating authorities in practice have a functioning experience feedback despite lack of systematic routines and methods. Yet, only four of the 21 participating authorities work with the whole experience feedback process. These four authorities have one common denominator; they have an experience feedback that is turning more inwards than outwards. All of the participating authorities have a need to improve and systematize the dissemination of experiences, knowledge and results. An improved dissemination can in fact affect other procedures such as the reporting of occurred accidents. Focus in this second study was on practical communication procedures, and how the authorities communicate results, knowledge and experiences within their own organisations, with other authorities, and with external parties. It is concluded that a more proactive approach would be valuable for the learning process.

Learning from accidents : Experience feedback in practice
- 2010
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Experience feedback from accidents is important for preventive work in companies, authorities and other organisations. This thesis focused on experience feedback from accidents that take place in everyday life, in our neighbourhoods, in our workplaces, in our schools, in traffic and transportation. Essay I is an overview of the literature on learning from accidents and incidents. The focus in this essay is on literature that evaluates the effectiveness and usefulness of different methods in accident investigations. Conclusions drawn from this literature review are that the dissemination of results and knowledge from accident investigations must be improved, and experience feedback systems should be integrated into overall systems of risk management. Essay II is based on an evaluation of the investigation board for workplace accidents (HAKO) that was carried out on commission of the Swedish Work Environment Authority. It was concluded that the accident reports published by HAKO had a high qualitative level but the dissemination of results from the investigations was weak. Essay III investigates twenty-eight supervision cases from eleven Swedish local Environment and Health Administrations. The overall goal of the study was to find out how, and to what extent, experience feedback occurs in Swedish municipalities. Two major problems relevant for the experience feedback have been found; namely that the inspectors do not have enough guidance on how to interpret the law and that they would like more information on what happens to legal cases that they have handed over to the public prosecutors and the police. Essay IV is a document study of incident reports from two municipal fire and rescue services. The overall purpose of this study was to investigate if information from the rescue services could be used to improve experience feedback in sectors where it is weak or non-existent. In the 1120 incident reports that were studied, we found 217 proposals for improvement but these proposals were not used for experience feedback. It is concluded that the reports contain valuable information but this information is not used to prevent future accidents. Essay V investigates experience feedback in Swedish authorities working with accident prevention. The essay is based on two interview studies. In the first study, 21 Swedish authorities participated, and several of these authorities seem to have a functioning experience feedback despite the lack of systematic routines and methods. Yet, only four of the 21 authorities actually handle the whole experience feedback process. These four have at least one common denominator; they have an experience feedback that is turning more inwards than outwards. The second study was a follow-up study of some of the results from the first study, concerning the dissemination of results from experience feedback.

Tidskriftsartikel (refereegranskat)abstract
- A model of experience feedback (the CHAIN model) that emphasizes the whole chain from initial reporting to preventive measures is used to identify important research needs in the field of learning from accidents. Based on the model, six quality criteria for experience feedback after an accident or incident are presented. Research on experience feedback from accidents is reviewed. The overall conclusion is that the discipline of experience feedback has not been sufficiently self-reflective. The process of experience feedback can and should be applied to experience feedback itself, but that is rarely done. Evaluation studies are needed that provide hard (evidence-based) information about the effects of various methodologies and organizational structures. Four types of studies are particularly important for the development of evidence-based accident investigation practices: (1) studies of the effects and the efficiency of different accident investigation methods, (2) studies of the dissemination of conclusions from accident investigation, (3) follow-up studies of the extent to which accident investigation reports give rise to actual preventive measures, and (4) studies of the integration of experience feedback systems into overall systems of risk management.

Learning from Experience in Municipal Environmental Supervision : A study of twenty-six Swedish supervion cases
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Twenty-six supervision cases from eleven Swedish municipal Environment and Health Administrations were examined. This was made in order to determine how and to what extent experience feedback and other exchange of experiences take place among municipal environment authorities and to identify unfulfilled demands of such communication. There was a remarkable lack of demand for classical experience feedback in which information from technological and organizational failures was used to avoid a repetition of the same type of failure. Instead, inspectors expressed a need for exchanges from other agencies dealing with similar issues and a need for systematic feedback from public prosecutors of cases that have been handed over to them.

Räddningstjänstens insatsrapporter : En studie av erfarenhetsåterföring i kommunal räddningstjänst
- 2009
-
Rapport (populärvet., debatt m.m.)abstract
- The 204 Swedish municipal rescue services carry through about 90 000 rescue turnouts per year. Every turnout is documented in a turnout report form. This study will show what can be learnt from municipal rescue services turnout reports. The main purpose of the study is to investigate how to improve and make experience feedback more effective in municipal rescue services. An underlying purpose is to examine what can be learnt about experience feedback with the turnout reports as point of departure. Experience feedback is a process which starts with the reporting of an accident or incident, and if it is necessary a selection procedure. The accident or incident is investigated and results from the investigation are disseminated. Finally preventive measures are taken. Two municipal rescue services provided the turnout reports. 1122 reports from turnouts carried through in 2006 were studied. The reports have been thoroughly read, divided into categories and analysed. The 215 improvement proposals found in the reports were especially examined and receivers for all proposals were identified. The CHAIN model has been used as a tool to study feedback processes from accident to prevention. It has become clear that the reporting of accidents is working properly and that selection of accidents in need of investigation is not relevant. The investigation procedure for accidents ending up in turnout reports needs some improvement since the quality of many reports is deficient. The dissemination of knowledge from the reports is in great need of improvement. Several improvement proposals were found in the reports but the proposals were not disseminated to people in organisations that can take precautionary measures. Receivers for all proposals can easily be identified in the reports but this needs to be systematized. The municipal rescue services reports are in their present shape an excellent foundation for statistics. However, with rather simple means their application field can be more effective and perhaps also become accident preventive.

Tidskriftsartikel (refereegranskat)abstract
- Estrogen is of importance for the regulation of trabecular bone mineral density (BMD). The aim of this study was to search for possible mechanisms of action of estrogen on bone. Ovariectomized (OVX) mice were treated with 17beta-estradiol. Possible effects of estrogen on the expression of 125 different bone-related genes in humerus were analyzed using the microarray technique. Estrogen regulated 12 of these genes, namely, two growth factor-related genes, 8 cytokines, and 2 bone matrix-related genes. Five of the 12 genes are known to be estrogen-regulated, and the remaining 7 genes are novel estrogen-regulated genes. Seven genes, including interleukin-1 receptor antagonist (IL-1ra), IL-1receptor type II (IL-1RII), insulin-like growth factor-binding protein 4 (IGFBP-4), transforming growth factor beta (TGF-beta), granulocyte colony-stimulating factor receptor (G-CSFR), leukemia inhibitory factor receptor (LIFR), and soluble IL-4 receptor (sIL-4R) were selected as probable candidate genes for the trabecular bone-sparing effect of estrogen, as the mRNA levels of these genes were highly correlated (r2 > 0.65) to the trabecular BMD. The regulation of most of these seven genes was predominantly estrogen receptor alpha (ER-alpha)-mediated (5/7) while some genes (2/7) were regulated both via ER-alpha and ER-beta. In conclusion, by using the microarray technique, we have identified four previously known and three novel estrogen-regulated genes of potential importance for the trabecular bone-sparing effect of estrogen.

- BACKGROUND: Obesity is a significant public health problem that is on the increase worldwide, and treatment with bariatric surgery is becoming more and more common. This type of surgery has proved to be good for weight reduction and for preventing complications, but few studies have investigated patients' long-term experiences of health and suffering.AIM: To explore people's experiences of health after bariatric surgery. What are their thoughts about their life, body and sexuality?METHODS: This study is based on semi-structured interviews with eight women and eight men, 4-6 years after bariatric surgery. The data were analysed using qualitative content analysis and resulted in 5 main themes and 14 subthemes.RESULTS: The new body enabled a healthy life due to better treatment in society, enhanced self-esteem, the pleasure of purchasing clothes and the courage to become more sexually active. At the same time, the body could be experienced as so unfamiliar that their life was dominated by despondency, a lack of freedom and a feeling of being lost, which made them wish to return to their old body.CONCLUSION AND IMPLICATIONS: The participants received extensive information before as well as follow-up conversations up to one year after surgery. Nevertheless, they all experienced that changing from life as an obese person to a radically reduced body often meant a confrontation with an unexpected reality that oscillated between health and suffering. This indicates that preparedness for the life changes that bariatric surgery may entail is inadequate and that moving towards health and suffering takes its own time. Therefore, more time should be allocated to talking about how life is and can become in the long term, which may facilitate a dialogical, person-centred approach to the setbacks and situations each person needs to manage in order to improve her/his health.

- Influenza is a contagious respiratory disease caused by an influenza virus. Due to continuous antigenic drift of seasonal influenza viruses, influenza vaccines need to be adjusted before every influenza season. This allows annual vaccination with multivalent seasonal influenza vaccines, recommended especially for high-risk groups. There is a need for a seasonal influenza vaccine that induces broader and longer lasting protection upon easy administration. Endocine™ is a lipid-based mucosal adjuvant composed of endogenous lipids found ubiquitously in the human body. Intranasal administration of influenza antigens mixed with this adjuvant has been shown to induce local and systemic immunity as well as protective efficacy against homologous influenza virus challenge in mice. Here we used ferrets, an established animal model for human influenza virus infections, to further investigate the potential of Endocine™ as an adjuvant. Intranasal administration of inactivated pandemic H1N1/California/2009 split antigen or whole virus antigen mixed with Endocine™ induced high levels of serum hemagglutination inhibition (HI) and virus neutralization (VN) antibody titers that were also cross reactive against distant swine viruses of the same subtype. HI and VN antibody titers were already demonstrated after a single nasal immunization. Upon intratracheal challenge with a homologous challenge virus (influenza virus H1N1/The Netherlands/602/2009) immunized ferrets were fully protected from virus replication in the lungs and largely protected against body weight loss, virus replication in the upper respiratory tract and pathological changes in the respiratory tract. Endocine™ formulated vaccines containing split antigen induced higher HI and VN antibody responses and better protection from body weight loss and virus shedding in the upper respiratory tract than the Endocine™ formulated vaccine containing whole virus antigen.

- The study investigated cytotoxicity of essential oils from four medicinal plants (Bidens pilosa, Ocimum gratissimum, Cymbopogon nardus, and Zanthoxylum chalybeum) on human gingival fibroblasts and their effects on proinflammatory mediators' secretion. Cytotoxicity of essential oils was investigated using 3-(4, 5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide assay. Effects of essential oils at subcytotoxicity concentrations on interleukin-(IL-) 6, IL-8, and prostaglandin E-2 (PGE(2)) secretions by gingival fibroblasts treated with IL-1 beta (300 pg/mL) were evaluated by ELISA and EIA. IC50 values of the essential oils ranged from 26 mu g/mL to 50 mu g/mL. Baseline and IL-1 beta-induced secretion of PGE(2) was inhibited by treatment with essential oil from O. gratissimum. Essential oils from B. pilosa and C. nardus had synergistic effects with IL-1 beta on PGE(2) seceretion. In conclusion, the study suggests that essential oil from O. gratissimum decreases gingival fibroblasts secretion of PGE(2), while essential oils from B. pilosa and C. nardus increase PGE(2) secretion. Essential oil from Z. chalybeum was the most cytotoxic, while oil from C. nardus was the least cytotoxic. Although the clinical significance of these findings remains to be determined, it may be suggested that essential oil from O. gratissimum, applied at subcytotoxicity concentrations, could reduce the participation of gingival fibroblasts in the gingival inflammation and tissue destruction associated with periodontitis.

- Purpose: Tumor classification is a key component in personalized cancer care. For soft-tissue and bone tumors, this classification is currently based primarily on morphology assessment and IHC staining. However, these standard-of-care methods can pose challenges for pathologists. We therefore assessed how whole-genome and whole-transcriptome sequencing (WGTS) impacted tumor classification and clinical management when interpreted together with histomorphology.Experimental Design: We prospectively evaluated WGTS in routine diagnostics of 200 soft-tissue and bone tumors suspicious for malignancy, including DNA and RNA isolation from the tumor, and DNA isolation from a peripheral blood sample or any non-tumor tissue.Results: On the basis of specific genomic alterations or absence of presumed findings, WGTS resulted in reclassification of 7% (13/197) of the histopathologic diagnoses. Four cases were downgraded from low-grade sarcomas to benign lesions, and two cases were reclassified as metastatic malignant melanomas. Fusion genes associated with specific tumor entities were found in 30 samples. For malignant soft-tissue and bone tumors, we identified treatment relevant variants in 15% of cases. Germline pathogenic variants associated with a hereditary cancer syndrome were found in 22 participants (11%).Conclusions: WGTS provides an important dimension of data that aids in the classification of soft-tissue and bone tumors, correcting a significant fraction of clinical diagnoses, and identifies molecular targets relevant for precision medicine. However, genetic findings need to be evaluated in their morphopathologic context, just as germline findings need to be evaluated in the context of patient phenotype and family history.

- OBJECTIVE: Parental feeding practices shape children's relationships with food and eating. Feeding is embedded socioculturally in values and attitudes related to food and parenting. However, few studies have examined associations between parental feeding practices and migrant background.DESIGN: Cross-sectional study. Parental feeding practices (restriction, pressure to eat, monitoring) were assessed using the Child Feeding Questionnaire. Differences were explored in four sub-samples grouped by maternal place of birth: Sweden, Nordic/Western Europe, Eastern/Southern Europe and countries outside Europe. Crude, partly and fully adjusted linear regression models were created. Potential confounding variables included child's age, gender and weight status, and mother's age, weight status, education and concern about child weight.SETTING: Malmö and Stockholm, Sweden.SUBJECTS: Mothers (n 1325, representing seventy-three countries; mean age 36·5 years; 28·1 % of non-Swedish background; 30·7 % with overweight/obesity; 62·8 % with university education) of pre-school children (mean age 4·8 years; 50·8 % boys; 18·6 % with overweight/obesity).RESULTS: Non-Swedish-born mothers, whether European-born or non-European-born, were more likely to use restriction. Swedish-born mothers and Nordic/Western European-born mothers reported lower levels of pressure to eat compared with mothers born in Eastern/Southern Europe and mothers born outside Europe. Differences in monitoring were small. Among the potential confounding variables, child weight status and concern about child weight were highly influential. Concern about child weight accounted for some of the effect of maternal origin on restriction.CONCLUSIONS: Non-European-born mothers were more concerned about children being overweight and more likely to report controlling feeding practices. Future research should examine acculturative and structural factors underlying differences in feeding.
