Abstract
Introduction The purpose of this paper is to contribute to the existing literature on performance in resistance training (RT) by addressing how a phenomenological perspective on experiences with inter kinaesthetic affectivity can illuminate experience of practicing RT with non-verbal, visual feedback provided through laser lights attached to the barbell. Method The material is created from qualitative interviews and using inter-kinaesthetic affectivity as analytical lenses. Results The findings show how participants interpret the feedback in the moment and explain how they adjust their movement in dialogue with the feedback and enable the "uptake" of feedback in their embodied experience. The findings show how the participants developed an awareness of how they can equalize the balance on their feet. Discussion We discuss what this means for the understanding of the training process in terms of how practitioners can use the uptake of non-verbal, visual feedback to immediately adjust the quality of their performance by responding kinaesthetically and bodily. The discussion contributes to the question of what kind of role a practitioner's own kinaesthetic and bodily experiences have in the development and organization of RT. Perspectives that include the lived and intersubjective body as a knowledge position are promising for illuminating the whole bodied engagement that is necessary to understand how to perform RT.

Abstract
Background:The interplay between genetics and drug response in rheumatoid arthritis (RA) has shown that response to biologics varies between individuals and that a large proportion of patients show no clinical improvement (Plenge and Bridges, 2011). Despite the disappointing scenario, to date, only a few genetic markers have been consistently identified and we are far from being able to optimize drug dosing or prioritize drug combinations based on genetic findings.Objectives:With this background, we sought to validate the association of GWAS-identified variants for response to TNF inhibitors (TNFi) in a two-stage case control association study and to shed some light into the functional role of the most interesting markers.Methods:The discovery population consisted of 1361 RA patients ascertained through the REPAIR consortium and the DANBIO registry. RA patients fulfilled the 1987 revised American College of Rheumatology (ACR) and the ACR/EULAR 2010 classification criteria. The validation cohort included 706 Dutch RA patients from the DREAM registry. The study followed the Declaration of Helsinki and study participants gave their written informed consent to participate in the study, which was approved by the ethical review committee of participant institutions. Twenty-seven single-nucleotide polymorphisms (SNPs) were selected through a literature search of relevant GWAS. Linear regression analysis adjusted for age, sex and country of origin was used to determine the association between GWAS-identified SNPs and changes in DAS28 (ΔDAS28) after 3 or 6 months of treatment. The meta-analysis of both populations was performed using a fixed effect model. Correction for multiple testing was performed using the Bonferroni method but also considering the number of inheritance models tested (P=0.0009). To assess the role of the most interesting markers in modulating immune responses, stimulation experiments in whole blood, peripheral mononuclear cells (PBMCs) and monocyte-derived macrophages using a large number of pathogens and microbiome bacteria were performed in 408 subjects from the Human Functional Genomic Project cohort. We also evaluated the correlation of these SNPs with plasmatic levels of 108 inflammatory proteins, 7 serum steroid hormones and counts of 91 blood-derived immune cell populations.Results:The meta-analysis of the discovery cohort and DREAM registry including 2067 RA patients treated with TNFi revealed an overall association of the LINC02549rs7767069 SNP with a decreased drop in DAS28 that remained significant after correction for multiple testing (per-allele ORMeta=0.83, PMeta=0.000077; PHet=0.61). In addition, the meta-analysis of these large cohorts showed that each copy of the LARRC55rs717117G allele significantly decreased the drop in DAS28 in RF-positive patients (per-allele ORMeta=0.67, P=0.00058; PHet=0.06) whereas an opposite but not significant effect was found in RF-negative subjects (per-allele ORMeta=1.38, P=0.10; PInteraction=0.00028; PHet=0.45). Interestingly, the meta-analysis also showed potentially interesting but not statistically significant overall and RF-specific associations for the MAFBrs6071980 and CNTN5rs1813443 SNPs with ΔDAS28 (per-allele ORMeta_rs6071980=0.84, P=0.0059; PHet=0.63 and ORMeta_rs1813443_RF+=0.81, P=0.0059; PHet=0.69 and ORMeta_rs1813443_RF-=1.00, P=0.99; PHet=0.12; PInteraction=0.032). Although analysis of functional data is ongoing, so far, we found that carriers of the LARRC55rs717117G allele showed decreased levels of IL6 after stimulation of PBMCs with Borrelia burgdorferi and Escherichia Coli bacteria (P=0.00046 and 0.00044), which suggested a reduced IL6-mediated anti-inflammatory effect of this marker to worsen the response to TNFi.Conclusion:This study confirmed the influence of the LINC02549 and LARRC55 loci to determine the response to TNFi in RA patients and a weak effect of the MAFB and CNTN5 loci that needs to be further investigated.References:[1]Plenge RM et al 2011.

Abstract
Background:Although causality remains to be established, targeting dysbiosis of the intestinal microbiota by faecal microbiota transplantation (FMT) has been proposed as a novel therapeutic option for treatment of extra-intestinal inflammatory diseases.1Objectives:In this proof-of-concept study, we evaluated efficacy and safety of FMT in psoriatic arthritis (PsA).2Methods:In this double-blind, parallel-group, sham-controlled, superiority trial, we randomly allocated (1:1) adults with active peripheral PsA (≥3 swollen joints) despite ongoing treatment with methotrexate to one gastroscopic-guided FMT or sham transplantation into the duodenum. The transplants (50 g faeces) came from one of four healthy, thoroughly screened, anonymous stool donors.3 The primary efficacy endpoint was the proportion of participants experiencing treatment failure (i.e., needing treatment intensification) through 26 weeks. The first key secondary endpoint was change in Health Assessment Questionnaire Disability Index (HAQ-DI) score from baseline to week 26. Safety was monitored throughout the trial. Trial registration number: NCT03058900, ClinicalTrials.gov.Results:Of 97 screened, 31 (32%) underwent randomisation (15 allocated to FMT), all received the assigned intervention, and 30 (97%) completed the 26-week clinical evaluation (Table 1). Treatment failure occurred more frequently in the FMT group than in the sham group (9 [60%] vs 3 [19%]; risk ratio, 3.20; 95% CI, 1.06 to 9.62; P=0.018). During the entire 26 weeks of observation, the rate of the treatment failures was significantly higher in the FMT than in the sham group, see figure 1. Improvement in HAQ-DI score differed between groups (0.07 vs 0.30) by 0.23 points (95% CI, 0.02 to 0.44; P=0.031) in favour of sham. No serious adverse events were observed.Conclusion:In this first interventional randomised controlled trial of FMT in immune-mediated arthritis, FMT was inferior to sham in treating active peripheral PsA. FMT did not appear to result in serious adverse events.Figure 1.Time-to-event curves by intervention group from baseline to week 26.

Abstract
Abstract
Introduction
Few studies have examined the role of maternal diet in relation to development of autoimmune diseases such as coeliac disease (CD). In Denmark, cancellation of mandatory vitamin D fortification of margarine in June 1985 provides this opportunity. This study examined if prenatal exposure to extra vitamin D from food fortification or season of birth were associated with a decreased risk of developing CD later in life. If low prenatal vitamin D levels are a risk factor, there are immediate, cheap and easy public health implications.
Methods
This register based study has a partially ecologic design. The two entire cohorts were created using information available from the Danish birth registry and development of CD (ICD-8 269 ICD-10 K90) over 30 years was retrieved from the Danish National Patient Register. Logistic regression analysis was used to generate odds ratios and 95% confidence intervals.
Results
There was a lower odds ratio of developing CD (OR: 0.811 95% CI 0.655; 1.003) from the exposed birth cohort adjusting for sex and season of birth. There was a significant season effect particularly for children born in autumn (OR 1.6 95% CI 1.16; 2.21) and born summer (OR 1.5 95% CI 1.1;2.1) when compared to children born in winter.
Conclusions
The results indicate a potential protective effect of a small extra intake of vitamin D from food fortification by pregnant women in relation to the risk of their offspring developing CD. This conclusion is further supported by the results showing that summer born children, where first half of gestation occurred during the dark winter season, had a higher risk of CD. This research lends support for the reconsideration of vitamin-D food fortification in Denmark.
Key messages
Exposure to even a small amount of vitamin D prenatally may protect against developing coeliac disease later in life. Association between season and CD indicates that vitamin D may play an important role in relation to fetal programming.

Abstract
Abstract
Introduction
Inflammatory bowel disease (IBD) is a chronic immune-mediated inflammatory disease that can affect the entire digestive tract. Approximately 1% of the Danish population has IBD today. Both the incidence and prevalence of IBD are increasing globally, but the etiology of IBD is still not fully understood. Some, but not all studies find that vitamin D has both protective and therapeutic effects on IBD. To our knowledge, no other study has investigated prenatal exposure to extra vitamin D from either fortified food, diet or supplements in relation to IBD. The aim of this study was to investigate whether a small extra dose of vitamin D from fortification during gestation, was associated with a lower risk of developing IBD in the offspring.
Methods
In 1985 mandatory fortification of margarine with vitamin D in Denmark was canceled. To investigate the effect of this policy change we selected all individuals from 2 full year birth cohorts before and after the termination of the mandatory fortification. All individuals were followed for 30 years. By merging data from the Medical Birth Registry with the Danish National Patient Registry, we identified individuals with IBD.
Results
217,249 individuals were included in the analysis. 875 among the exposed and 1102 among the unexposed fulfilled the criteria for being diagnosed with IBD. A lower odds ratio OR = 0.867 (95% CI: 0.792;0.947) for IBD was observed among those who had been exposed to extra vitamin D from fortified margarine during gestation, compared to those who had not been exposed. The analysis was adjusted for sex and season of birth, but results were essentially similar before and after this adjustment.
Conclusions
This study shows, that a small extra dose of vitamin D from fortified margarine during gestation may lower the risk of developing IBD in the offspring, until the age of 30. If these results can be replicated, fortification with vitamin D could be recommended to prevent IBD on a public level.
Key messages
Prenatal exposure of vitamin D from fortified food could lower the risk of IBD later in life. Fortification with vitamin D even at a relatively low level could have public health benefits.

Abstract
Rheumatoid arthritis (RA) is a chronic inflammatory disease that affects ~1% of the Caucasian population. Over the last decades, the availability of biological drugs targeting the proinflammatory cytokine tumour necrosis factor α, anti-TNF drugs, has improved the treatment of patients with RA. However, one-third of the patients do not respond to the treatment. We wanted to evaluate the status of pharmacogenomics of anti-TNF treatment. We performed a PubMed literature search and all studies reporting original data on associations between genetic variants and anti-TNF treatment response in RA patients were included and results evaluated by meta-analysis. In total, 25 single nucleotide polymorphisms were found to be associated with anti-TNF treatment response in RA (19 from genome-wide association studies and 6 from the meta-analyses), and these map to genes involved in T cell function, NFκB and TNF signalling pathways (including CTCN5, TEC, PTPRC, FCGR2A, NFKBIB, FCGR2A, IRAK3). Explorative prediction analyses found that biomarkers for clinical treatment selection are not yet available.

Abstract
BACKGROUND Personalised medicine, including biomarkers for treatment selection, may provide new algorithms for more effective treatment of patients. Genetic variation may impact drug response and genetic markers could help selecting the best treatment strategy for the individual patient. AIM To identify polymorphisms and candidate genes from the literature that are associated with anti-tumour necrosis factor (TNF) treatment response in patients with inflammatory bowel diseases (IBD), Crohn's disease (CD) and ulcerative colitis. METHODS We performed a PubMed literature search and retrieved studies reporting original data on association between polymorphisms and anti-TNF treatment response and conducted a meta-analysis. RESULTS A functional polymorphism in FCGR3A was significantly associated with anti-TNF treatment response among CD patients using biological response criterion (decrease in C-reactive protein, levels). Meta-analyses showed that polymorphisms in TLR2 (rs3804099, OR (95% CI) = 2.17 (1.35-3.47)], rs11938228 [OR = 0.64 (0.43-0.96)], TLR4 (rs5030728) [OR = 3.18 (1.63-6.21)], TLR9 (rs352139) [OR = 0.43 (0.21-0.88)], TNFRSF1A (rs4149570) [OR = 2.06 (1.02-4.17)], IFNG (rs2430561) [OR = 1.66 (1.05-2.63)], IL6 (rs10499563) [OR = 1.65 (1.04-2.63)] and IL1B (rs4848306) [OR = 1.88 (1.05-3.35)] were significantly associated with response among IBD patients using clinical response criteria. A positive predictive value of 0.96 was achieved by combining five genetic markers in an explorative analysis. CONCLUSIONS There are no genetic markers currently available which are adequately predictive of anti-TNF response for use in the clinic. Genetic markers bear the advantage that they do not change over time. Therefore, hypothesis-free approaches, testing a large number of polymorphisms in large, well-characterised cohorts, are required in order to identify genetic profiles with larger effect sizes, which could be employed as biomarkers for treatment selection in clinical settings.

The purpose of the study was to compare core muscle activation in 3 different row exercises (free-weight bent-over row, seated cable row and machine row) performed unilaterally and bilaterally, at matched effort levels. 15 resistance-trained men (26.0±4.4 years, 81.0±9.5 kg, 1.81±0.07 m) performed the exercises in randomized order. For erector spinae and multifidus, EMG activities in unilateral machine- and cable row were 60-63% and 74-78% of the bilateral performance (P≤0.036). For external oblique, the EMG activities recorded during bilateral exercises were 37-41% of the unilateral performance (P≤0.010). In unilateral cable- and machine rows, the EMG activities in external oblique and multifidus were 50-57% and 70-73% of the free-weight row (P≤0.002). In bilateral free-weight row, EMG activity in erector spinae was greater than bilateral machine- (+34%, P=0.004) and unilateral free-weight rows (+12%, P=0.016). For rectus abdominis there were no significant differences between conditions. In conclusion, 1) free-weight row provided greater EMG activity in erector spinae (bilaterally and unilaterally) and multifidus (unilaterally) than machine row; 2) unilateral performance of exercises activated the external oblique more than bilateral performance, regardless of exercise; and 3) generally bilateral performance of exercises provided higher erector spinae and multifidus EMG activity compared to unilateral performance.

Abstract
BACKGROUND & AIMS Health-related quality of life (HRQoL) is impaired in patients with Inflammatory Bowel Disease (IBD). The aim was prospectively to assess and validate the pattern of HRQoL in an unselected, population-based inception cohort of IBD patients from Eastern and Western Europe. METHODS The EpiCom inception cohort consists of 1560 IBD patients from 31 European centres covering a background population of approximately 10.1 million. Patients answered the disease specific Short Inflammatory Bowel Disease Questionnaire (SIBDQ) and generic Short Form 12 (SF-12) questionnaire at diagnosis and after one year of follow-up. RESULTS In total, 1079 patients were included in this study. Crohn's disease (CD) patients mean SIBDQ scores improved from 45.3 to 55.3 in Eastern Europe and from 44.9 to 53.6 in Western Europe. SIBDQ scores for ulcerative colitis (UC) patients improved from 44.9 to 57.4 and from 48.8 to 55.7, respectively. UC patients needing surgery or biologicals had lower SIBDQ scores before and after compared to the rest, while biological therapy improved SIBDQ scores in CD. CD and UC patients in both regions improved all SF-12 scores. Only Eastern European UC patients achieved SF-12 summary scores equal to or above the normal population. CONCLUSION Medical and surgical treatment improved HRQoL during the first year of disease. The majority of IBD patients in both Eastern and Western Europe reported a positive perception of disease-specific but not generic HRQoL. Biological therapy improved HRQoL in CD patients, while UC patients in need of surgery or biological therapy experienced lower perceptions of HRQoL than the rest.

Abstract
BACKGROUND AND AIMS The EpiCom study and inception cohort was initiated in 2010 in 31 centers from 14 Western and 8 Eastern European countries, covering a 10.1million person background population. Our aim was to investigate whether there is a difference between Eastern and Western Europe in health care and education of patients with inflammatory bowel disease (IBD). METHODS A quality of care (QoC) questionnaire was developed in the EpiCom group consisting of 16 questions covering 5 items: time interval between the onset of symptoms and diagnosis, information, education, empathy and access to health care providers. RESULTS Of 1,515 patients, 947 (217 east/730 west) answered the QoC questionnaire. Only 23% of all patients had knowledge about IBD before diagnosis. In Eastern Europe, significantly more patients searched out information about IBD themselves (77% vs. 68%, p<0.05), the main source was the Internet (92% vs. 88% p=0.23). In Western Europe, significantly more patients were educated by nurses (19% vs. 1%, p<0.05), while in Eastern Europe, gastroenterologists were easier to contact (80% vs. 68%, p<0.05). CONCLUSION Health care differed significantly between Eastern and Western Europe in all items, but satisfaction rates were high in both geographic regions. Because of the low awareness and the rising incidence of IBD, general information should be the focus of patient organizations and medical societies. In Western Europe IBD nurses play a very important role in reducing the burden of patient management.

Abstract
BACKGROUND AND AIMS The incidence of inflammatory bowel disease (IBD) is increasing in Eastern Europe possibly due to changes in environmental factors towards a more "westernised" standard of living. The aim of this study was to investigate differences in exposure to environmental factors prior to diagnosis in Eastern and Western European IBD patients. METHODS The EpiCom cohort is a population-based, prospective inception cohort of 1560 unselected IBD patients from 31 European countries covering a background population of 10.1 million. At the time of diagnosis patients were asked to complete an 87-item questionnaire concerning environmental factors. RESULTS A total of 1182 patients (76%) answered the questionnaire, 444 (38%) had Crohn's disease (CD), 627 (53%) ulcerative colitis (UC), and 111 (9%) IBD unclassified. No geographic differences regarding smoking status, caffeine intake, use of oral contraceptives, or number of first-degree relatives with IBD were found. Sugar intake was higher in CD and UC patients from Eastern Europe than in Western Europe while fibre intake was lower (p<0.01). Daily consumption of fast food as well as appendectomy before the age of 20 was more frequent in Eastern European than in Western European UC patients (p<0.01). Eastern European CD and UC patients had received more vaccinations and experienced fewer childhood infections than Western European patients (p<0.01). CONCLUSIONS In this European population-based inception cohort of unselected IBD patients, Eastern and Western European patients differed in environmental factors prior to diagnosis. Eastern European patients exhibited higher occurrences of suspected risk factors for IBD included in the Western lifestyle.

Abstract
BACKGROUND Nonsteroidal anti-inflammatory drugs (NSAIDs) include aspirin (acetylsalicylic acid, ASA). Long-term use of NSAIDs has been associated with lowered risk of colorectal cancer (CRC), but the use is hampered by adverse effects. Also, the anti-carcinogenic effects of NSAIDs are incompletely understood. Understanding biological effects of NSAIDs may help developing new preventive medical strategies. AIM To identify gene-environment interactions between genetic variation and NSAID use in relation to risk of CRC. METHODS We performed a PubMed literature search and all studies reporting original data on interactions between NSAIDs and polymorphisms in relation to CRC were evaluated. RESULTS We found indications that aspirin interacted with rs6983267 close to MYC (encoding a transcription factor involved in cell cycle progression, apoptosis and cellular transformation) and NSAIDs interacted with rs3024505 and rs1800872 in or close to IL10 (encoding IL-10) in preventing CRC. Homozygous carriers of the variant allele of rs6983267 (ca. 25% of the population) halved their risk for CRC by aspirin use compared to homozygous wildtype carriers who did not benefit from aspirin intake. No interaction between use of NSAIDs and PTGS-2 (encoding COX-2) in relation to CRC risk was detected. Other findings of interactions between genes in inflammatory and oncogenic pathways and NSAIDs were considered suggestive. CONCLUSIONS Knowledge of underlying biological effects of NSAIDs in relation to CRC is scarce and the basis for stratifying the patients for preventive treatment is not yet available. Further studies assessing interactions between long-term NSAID exposure and genetic variation in relation to CRC are warranted in large well-characterised prospective cohorts.

Abstract
Antitumor necrosis factor-α (TNF-α) is used for treatment of severe cases of inflammatory bowel diseases (IBD), including Crohn's disease (CD) and ulcerative colitis (UC). However, one-third of the patients do not respond to the treatment. Genetic markers may predict individual response to anti-TNF therapy. Using a candidate gene approach, 39 mainly functional single nucleotide polymorphisms (SNPs) in 26 genes regulating inflammation were assessed in 738 prior anti-TNF-naive Danish patients with IBD. The results were analyzed using logistic regression (crude and adjusted for age, gender and smoking status). Nineteen functional polymorphisms that alter the NFκB-mediated inflammatory response (TLR2 (rs3804099, rs11938228, rs1816702, rs4696480), TLR4 (rs5030728, rs1554973), TLR9 (rs187084, rs352139), LY96 (MD-2) (rs11465996), CD14 (rs2569190), MAP3K14 (NIK) (rs7222094)), TNF-α signaling (TNFA (TNF-α) (rs361525), TNFRSF1A (TNFR1) (rs4149570), TNFAIP3(A20) (rs6927172)) and other cytokines regulated by NFκB (IL1B (rs4848306), IL1RN (rs4251961), IL6 (rs10499563), IL17A (rs2275913), IFNG (rs2430561)) were associated with response to anti-TNF therapy among patients with CD, UC or both CD and UC (P ⩽ 0.05). In conclusion, the results suggest that polymorphisms in genes involved in activating NFκB through the Toll-like receptor (TLR) pathways, genes regulating TNF-α signaling and cytokines regulated by NFκB are important predictors for the response to anti-TNF therapy among patients with IBD. Genetically strong TNF-mediated inflammatory response was associated with beneficial response. In addition, the cytokines IL-1β, IL-6 and IFN-γ may be potential targets for treating patients with IBD who do not respond to anti-TNF therapy. These findings should be examined in independent cohorts before these results are applied in a clinical setting.

Abstract
OBJECTIVE The incidence of inflammatory bowel disease (IBD) is increasing in Eastern Europe. The reasons for these changes remain unknown. The aim of this study was to investigate whether an East-West gradient in the incidence of IBD in Europe exists. DESIGN A prospective, uniformly diagnosed, population based inception cohort of IBD patients in 31 centres from 14 Western and eight Eastern European countries covering a total background population of approximately 10.1 million people was created. One-third of the centres had previous experience with inception cohorts. Patients were entered into a low cost, web based epidemiological database, making participation possible regardless of socioeconomic status and prior experience. RESULTS 1515 patients aged 15 years or older were included, of whom 535 (35%) were diagnosed with Crohn's disease (CD), 813 (54%) with ulcerative colitis (UC) and 167 (11%) with IBD unclassified (IBDU). The overall incidence rate ratios in all Western European centres were 1.9 (95% CI 1.5 to 2.4) for CD and 2.1 (95% CI 1.8 to 2.6) for UC compared with Eastern European centres. The median crude annual incidence rates per 100,000 in 2010 for CD were 6.5 (range 0-10.7) in Western European centres and 3.1 (range 0.4-11.5) in Eastern European centres, for UC 10.8 (range 2.9-31.5) and 4.1 (range 2.4-10.3), respectively, and for IBDU 1.9 (range 0-39.4) and 0 (range 0-1.2), respectively. In Western Europe, 92% of CD, 78% of UC and 74% of IBDU patients had a colonoscopy performed as the diagnostic procedure compared with 90%, 100% and 96%, respectively, in Eastern Europe. 8% of CD and 1% of UC patients in both regions underwent surgery within the first 3 months of the onset of disease. 7% of CD patients and 3% of UC patients from Western Europe received biological treatment as rescue therapy. Of all European CD patients, 20% received only 5-aminosalicylates as induction therapy. CONCLUSIONS An East-West gradient in IBD incidence exists in Europe. Among this inception cohort--including indolent and aggressive cases--international guidelines for diagnosis and initial treatment are not being followed uniformly by physicians.

Abstract
BACKGROUND Diet contributes significantly to colorectal cancer (CRC) aetiology and may be potentially modifiable. AIM To review diet-gene interactions, aiming to further the understanding of the underlying biological pathways in CRC development. METHODS The PubMed and Medline were systematically searched for prospective studies in relation to diet, colorectal cancer and genetics. RESULTS In a meta-analysis, no interaction between NAT1 phenotypes and meat intake in relation to risk of CRC was found (P-value for interaction 0.95). We found a trend towards interaction between NAT2 phenotypes and meat intake in relation to risk of CRC. High meat intake was not associated with risk of CRC among carriers of the slow NAT2 phenotype, whereas NAT2 fast acetylators with high meat intake were at increased risk of CRC (OR = 1.25; 95% confidence interval (CI): 0.92-2.01) compared with slow acetylators with low meat intake (reference), P-value for interaction = 0.07. Low meat intake in the studied populations may influence the result. Interactions between meat, cruciferous vegetables, fibres, calcium, vitamins, and alcohol and ABCB1, NFKB1, GSTM1, GSTT1, CCND1, VDR, MGTM, IL10 and PPARG are suggested. CONCLUSIONS A number of interactions between genetic variation and diet are suggested, but the findings need replication in independent, prospective, and well-characterised cohorts before conclusions regarding the underlying biological mechanisms can be reached. When the above criteria are met, studies on diet-gene interactions may contribute valuable insight into the biological mechanisms underlying the role of various dietary items in colorectal carcinogenesis.

Abstract
Seven patients (6 with connective tissue diseases, 1 with bronchial asthma) have been studied before, during, and after prednisone therapy. Maximum dose was 15 mg daily, which was tapered off to zero within three months. All patients showed striking subjective improvement during therapy. The ESR reflected this improvement but the acute phase proteins did not. The serum concentration of prealbumin rose significantly during the period of most intensive steroid treatment. IgE decreased in the patient with bronchial asthma, but otherwise the immunoglobulins did not change, and positive serological tests remained unchanged. Contact sensitization to haptens was induced without impairment during therapy. Prednisone induced rises in blood lymphocyte and neutrophil concentrations. Lymphocyte transformation, both mitogen- and antigen-induced, was not influenced by therapy, but PPD-induced inhibition of leucocyte migration decreased. Neutrophil phagocytosis was unimparied, but bactericidal capacity, stimulated nitroblue tetrazolium reduction, and neutrophil and plasma lysozyme concentrations were all depressed during treatment with prednisone.

Abstract
OBJECTIVE P-glycoprotein (Pgp) plays a part in the intestinal uptake of xenobiotics and has been associated with susceptibility to ulcerative colitis. The aim of this study was to examine Pgp activity in relation to age, gender, medical treatment (rifampicin or ketoconazole) and the multidrug resistance (MDR1) gene single nucleotide polymorphisms (SNPs) G2677T and C3435T using the model drug digoxin. MATERIAL AND METHODS Pgp activity was estimated from the pharmacokinetics of orally administered digoxin in blood samples from 32 healthy subjects. MDR1 gene expression in duodenal biopsies was monitored by real-time quantitative RT-PCR (RQ-PCR) and Western blot analyses. MDR1 SNPs were determined by PCR-restriction fragment length polymorphism (PCR-RFLP). The effect of medical treatment was tested by open, randomized, cross-over treatment with rifampicin and ketoconazole. RESULTS Rifampicin treatment resulted in increased Pgp activity, duodenal MDR1 mRNA expression and Pgp detection compared with that in the control group (p<0.05 for all), Pgp activity being associated with duodenal MDR1 mRNA level (p<0.05). Individuals homozygous for the 3435 wild-type allele (CC) showed higher Pgp activity (p<0.05), whereas SNP 2677 apparently did not affect Pgp activity. No variation in Pgp in relation to age or gender was found. CONCLUSIONS Our data confirm that rifampicin increases Pgp activity, by increasing MDR1 mRNA and Pgp levels. Moreover, we found that the wild-type allele of the synonymous polymorphism of MDR1 position 3435 confers a higher Pgp activity. These data support other findings suggesting an effect of Pgp on treatment response and disease susceptibility.

Abstract
The modeling of ion transport and interactions in matter is a subject of growing interest, driven by the continuous increase of possible application fields. These include hadron therapy, dosimetry, and space missions, but there are also several issues involving fundamental research, accelerator physics, and cosmic ray physics, where a reliable description of heavy ion induced cascades is important. In the present work, the capabilities of the FLUKA code for ion beams will be briefly recalled and some recent developments presented. Applications of the code to the simulation of therapeutic carbon, nitrogen and oxygen ion beams, and of iron beams, which are of direct interest for space mission related experiments, will be also presented together with interesting consideration relative to the evaluation of dosimetric quantities. Both applications involve ion beams in the AGeV range.

Abstract
The FLUKA Monte Carlo code has been evolving over the last several decades and is now widely used for radiation shielding calculations. In order to facilitate the use of FLUKA in dosimetry and therapy applications, supporting software has been developed to allow the direct conversion of the output files from standard CT-scans directly into a voxel geometry for transport within FLUKA. Since the CT-scan information essentially contains only the electron density information over the scanned volume, one needs the specific compositions for each voxel individually. We present here the results of a simple algorithm to assign tissues in the human body to one of four categories: soft-tissue, hard-bone, trabecular-bone and porous-lung. In addition, we explore the problem of the pathlength distributions in porous media such as trabecular bone. A mechanism will be implemented within FLUKA to allow for variable multipal fixed density materials to accommodate the pathlength distributions discovered.

Abstract
The FLUKA Monte Carlo transport code is widely used for fundamental research, radioprotection and dosimetry, hybrid nuclear energy system and cosmic ray calculations. The validity of its physical models has been benchmarked against a variety of experimental data over a wide range of energies, ranging from accelerator data to cosmic ray showers in the earth atmosphere. The code is presently undergoing several developments in order to better fit the needs of space applications. The generation of particle spectra according to up-to-date cosmic ray data as well as the effect of the solar and geomagnetic modulation have been implemented and already successfully applied to a variety of problems. The implementation of suitable models for heavy ion nuclear interactions has reached an operational stage. At medium/high energy FLUKA is using the DPMJET model. The major task of incorporating heavy ion interactions from a few GeV/n down to the threshold for inelastic collisions is also progressing and promising results have been obtained using a modified version of the RQMD-2.4 code. This interim solution is now fully operational, while waiting for the development of new models based on the FLUKA hadron-nucleus interaction code, a newly developed QMD code, and the implementation of the Boltzmann master equation theory for low energy ion interactions.

Abstract
Space radiation presents a hazard to astronauts, particularly those journeying outside the protective influence of the geomagnetosphere. Crews on future missions to Mars will be exposed to the harsh radiation environment of deep space during the transit between Earth and Mars. Once on Mars, they will encounter radiation that is only slightly reduced, compared to free space, by the thin Martian atmosphere. NASA is obliged to minimize, where possible, the radiation exposures received by astronauts. Thus, as a precursor to eventual human exploration, it is necessary to measure the Martian radiation environment in detail. The MARIE experiment, aboard the 2001 Mars Odyssey spacecraft, is returning the first data that bear directly on this problem. Here we provide an overview of the experiment, including introductory material on space radiation and radiation dosimetry, a description of the detector, model predictions of the radiation environment at Mars, and preliminary dose-rate data obtained at Mars.

Abstract
The extremely high risk reported for some types of cancer among patients with common variable immunodeficiency (CVID) is based on a limited number of investigations. Therefore, we examined the risks for cancer among 562 Danish and Swedish patients with CVID or IgA deficiency and 2071 relatives in 1958-96. The patients were identified through an Immunodeficiency Register and hospital records, while the relatives were traced through population registers. Cancer incidence was assessed by linkage to the Cancer Registries and compared with that in the general population. Among 386 patients with IgA deficiency, the incidence of cancer was not increased (standardized incidence ratio (SI) = 1.0); but two cases of stomach cancer were found, resulting in a non-significant increase in risk (SIR = 5.4; 95% CI = 0.7-19.5). Among 176 patients with common variable immunodeficiency (CVID), the incidence of cancer at all sites combined was increased (SIR = 1.8; 95% CI = 1.0-2.9), which was due mainly to significant excesses of malignant lymphoma (obs = 4; SIR = 12.1; 95% CI = 3.3-31.0) and of stomach cancer (obs = 3; SIR = 10.3; 95% CI = 2.1-30.2). Among the 626 relatives of patients with CVID, no increase in risk was found for these types of cancer or for cancer overall (obs = 53; SIR = 1.0; 95% CI = 0.8-1.3). Our data show that the risks for malignant lymphoma and stomach cancer among patients with CVID may be lower than reported previously. The absence of an increased risk among relatives suggests that the increased cancer morbidity in patients with CVID is related to the immunodeficiency per se rather than to specific genetic traits shared with their relatives.

Abstract
BACKGROUND & AIMS Up-regulation of urea synthesis by amino acids and dietary protein intake may be impaired in patients with chronic pancreatitis (CP) due to the reduced glucagon secretion. Conversely, urea synthesis may be increased as a result of the chronic inflammation. The aims of the study were to determine urea synthesis kinetics in CP patients in relation to glucagon secretion (study I) and during an increase in protein intake (study II). METHODS In study I, urea synthesis rate, calculated as urinary excretion rate corrected for accumulation in total body water and intestinal loss, was measured during infusion of alanine in 7 CP patients and 5 control subjects on spontaneous protein intake. The functional hepatic nitrogen clearance (FHNC), i.e. urea synthesis expressed independent of changes in plasma amino acid concentration, was calculated as the slope of the linear relation between urea synthesis rate and plasma alpha -amino nitrogen concentration. In study II, 6 of the patients of study I had urea synthesis and FHNC determined before and after a period of 14 days of supplementation with a protein-enriched liquid (dietary sequence randomized). RESULTS Study I: Alanine infusion increased urea synthesis rate by a factor of 10 in the control subjects, and by a factor of 5 in the CP patients (P<0.01). FHNC was 31.9+/-2.4 l/h in the control subjects and 16.5+/-2.0 l/h (P<0.05) in the CP patients. The glucagon response to alanine infusion (AUC) was reduced by 75 % in the CP patients. The reduction in FHNC paralleled the reduced glucagon response (r(2)=0.55, P<0.01). Study II: The spontaneous protein intake was 0.75+/-0.14 g/(kg x day) and increased during the high protein period to 1.77+/-0.12 g/(kg x day). This increased alanine stimulated urea synthesis by a factor of 1.3 (P<0.05), FHNC from 13.5+/-2.6 l/h to 19.4+/-3.1 l/h (P<0.01), and the glucagon response to alanine infusion (AUC) by a factor of 1.8 (P<0.05). CONCLUSIONS Urea synthesis rate and FHNC are markedly reduced in CP patients. This is associated with, and probably a result of, impaired glucagon secretion, and predicts a lower than normal postprandial hepatic loss of amino nitrogen. An increase in dietary protein intake increases alanine stimulated urea synthesis and FHNC by a mechanism that involves an increase in glucagon. This indicates that the low FHNC during spontaneous protein intake included an adaptation to the low protein intake, effectuated by a further decrease in glucagon secretion.

Abstract
OBJECTIVES To present an update on drug-induced pancreatitis reported to the Danish Committee on Adverse Drug Reactions. DESIGN Retrospective study of spontaneous case reports to the Danish reporting system on adverse drug reactions. METHODS All cases of suspected drug-induced pancreatitis reported to the Danish Committee on Adverse Drug Reactions from 1968 to 1999 were analysed. Three cases were excluded leaving 47 cases for analysis. RESULTS Drug-induced pancreatitis made up 0. 1% of all the reports to the committee from 1968 to 1999. The proportion seemed to increase and was 0.3% during the last 8 years. The 47 cases corresponded to 0.1% of the number of patients discharged due to pancreatic disease (without cancers) per year in Denmark. Serious courses were frequent as indicated by death and hospitalisation being reported in 4 (9%) and 32 (68%) cases, respectively. Death occurred after valproate (two cases), clomipramine (one case) and azathioprine (one case). Definite relationship was stated for mesalazine (three cases), azathioprine (two cases) and simvastatin (one case) on the basis of re-challenge. A possible or probable causality was considered for a further 30 drugs including 5-acetylsalicylic acid agents, angiotensin-converting enzyme inhibitors, estrogen preparations, didanosine, valproate, codeine, antiviral agents used in acquired immunodeficiency syndrome therapy, various lipid-reducing agents, interferon, paracetamol, griseofulvin, ticlopine, allopurinol, lithium and the MMR (measles" mumps/rubella) vaccination. CONCLUSION Drug-induced pancreatitis is rarely reported. The incidence may be increasing and the course is often serious. This is the first report on definite simvastatin-induced pancreatitis. Further studies on the pancreotoxic potential of drugs are warranted.

Abstract
Female birds frequently copulate with extra-pair males, but the adaptive value of this behaviour is poorly understood. Some studies have suggested that 'good genes' may be involved, where females seek to have their eggs fertilized by high-quality males without receiving any material benefits from them. Nevertheless, it remains to be shown that a genetic benefit is passed on to offspring. Here we report that nestling bluethroats, Luscinia svecica, sired by extra-pair males had a higher T-cell-mediated immune response than their maternal half-siblings raised in the same nest. The difference could not be attributed to nestling body mass, sex or hatching order, but may be an effect of paternal genotype. Extra-pair young were also more immunocompetent than their paternal half-sibs raised in the genetic father's own nest, which indicates an additional effect of maternal genotype. Our results are consistent with the idea that females engage in extra-pair copulations to obtain compatible viability genes, rather than 'good genes' per se.

Abstract
OBJECTIVE We investigated whether polymorphisms in the gene of mannose binding lectin (MBL) may be associated with onset of rheumatoid arthritis (RA), and whether MBL in conjunction with aggregated agalactosyl IgG (IgG-G0) may be associated with clinical and paraclinical variables. METHODS MBL genotypes and serum concentrations were measured by polymerase chain reaction and ELISA in 189 patients with established RA. Binding of purified MBL to IgG-G0 in serum was assessed and clinical and paraclinical variables were recorded. RESULTS The median age at onset of RA in the 3 genotypes (normal: A/A, hetero: A/0, and homozygous: 0/0 for variant alleles) was 54.1 (n = 108), 47.0 (n = 68), and 38.4 years (n = 13), respectively (p = 0.01). The frequency of variant alleles in patients with onset below the median age (50.8 yrs) was 0.32, but was 0.17 in patients with onset above 50.8 years (p = 0.003) and 0.20 in 250 controls (p = 0.001). Stratification according to erosion score (no, small, large) revealed an increasing tendency among the different groups in binding of MBL to IgG-G0, increased Health Assessment Questionnaire score, and acute phase reactants in A/A individuals, while no difference was seen among carriers of variant alleles. This effect was most pronounced in those with late onset RA. CONCLUSION Presence of MBL variant alleles was associated with early onset of RA. MBL deficiency may, therefore, accelerate the disease. However, in patients with late onset and advanced disease our results indicate that the A/A type may be associated with additional inflammation different from that seen in carriers of variant alleles.

Abstract
OBJECTIVE To determine whether variant alleles in the coding portion of the mannose-binding lectin (MBL) gene are associated with increased susceptibility to systemic lupus erythematosus (SLE) and concomitant infections. METHODS MBL alleles and serum concentrations were determined by polymerase chain reaction and enzyme-linked immunosorbent assay, respectively, in 91 Danish patients with SLE and in 250 controls. RESULTS Homozygosity for MBL variant alleles was observed in 7.7% of the SLE patients compared with 2.8% of the controls (P = 0.06), while no difference was seen for heterozygosity (33.0% versus 34.4%). Homozygotes had an increased risk of acquiring serious infections compared with patients who were heterozygous or homozygous for the normal allele (odds ratio 8.6, 95% confidence interval 1.5-47.6, P = 0.01). The time interval from the diagnosis of SLE to the first infectious event was shorter (P = 0.017), and the annual number of infectious events was 4 times higher, among homozygotes (P = 0.00002). They were especially prone to acquire pneumonia (P = 0.00004). CONCLUSION; Homozygosity for MBL variant alleles may explain much of the increased risk of complicating infections seen in SLE patients. Additionally, it is a minor risk factor for acquiring SLE.

Abstract
BACKGROUND Hepatic drug metabolism was examined in patients with chronic pancreatitis and healthy controls by using a cocktail design with three different model compounds: antipyrine to express phase-I oxidation, oxazepam to express phase-II conjugation, and indocyanine green (ICG), a high-clearance compound. METHODS Eight patients with chronic pancreatitis and seven healthy controls participated. Patients were diagnosed by the presence of typical morphologic changes of the pancreas on imaging and had a moderately but significantly reduced exocrine function and no or only slight impairment of the glucose tolerance. No one had a history or clinical signs of liver disease. Clearance of the three model compounds was estimated after the administration of 1 g antipyrine and 15 mg oxazepam orally and a bolus of indocyanine green, 0.5 mg/kg body weight, intravenously. RESULTS The antipyrine clearance and ICG clearance were significantly decreased in the patients compared with the controls (mean, 27.2 ml/min; 95% confidence interval (CI), 19.4-35; versus 46.2 ml/min; 34.7-58.7, and 501 ml/min; 4014601, versus 771 mU/min; 677-865 (P < 0.05), respectively). The oxazepam clearance did not differ significantly between the two groups (181 ml/min (145-217) versus 178 ml/min (152-204)). The model drug clearance ratios between the patient and control clearances showed decreased values for antipyrine and ICG compared with the oxazepam data (0.59 and 0.65 versus 1.02, respectively). Patients and controls were characterized by a body weight of 58.2 kg (53.1-63.3) and 83.4 kg (72.7-94.1), respectively, and a body mass index (BMI) of 19.6 kg/m2 (17.9-21.3) versus 25.9 kg/m2 (23.4-28.4) (P < 0.05 for both). CONCLUSIONS Patients with chronic pancreatitis characterized by a moderately reduced exocrine function and absence of diabetes mellitus and overt liver disease had a decreased antipyrine oxidation and ICG clearance, whereas no difference was seen in oxazepam conjugation when compared with healthy volunteers. In chronic pancreatitis the hepatic phase-I oxidation is reduced compared with the phase-II conjugation, as shown by the model drug clearance ratios. The clearance of ICG was also affected, pointing at a reduced hepatic plasma flow, provided that the hepatic extraction fraction is normal for these patients.

Abstract
BACKGROUND The aim of the study was to examine liver volume, portal vein flow, and indocyanine green (ICG) and antipyrine clearance in hyperthyroidism before and after antithyroid drug treatment. METHODS Liver volume and blood flow in the portal vein were investigated in nine fasting patients with hyperthyroidism by means of computed tomography scan and Doppler ultrasound, respectively. ICG clearance was estimated by bolus injection of ICG (0.5 mg/kg body weight) and antipyrine clearance with a one-sample technique. All patients were investigated before and after 3 months of antithyroid treatment, when euthyroidism had been achieved. The Wilcoxon matched-pairs test was used for statistical analysis. RESULTS The median liver volume increased by 238 (155-289) ml (median, 95% confidence interval), corresponding to 19%, and the weight by 5.0 (0.0-8.0) kg (8%), and the antipyrine clearance decreased by 8 (3.1-34.4) ml/min (16%). These changes were all significant (P < 0.05). The relation between liver volume and body weight increased from 19.9 (16.5-23.7) ml/kg to 21.4 (17.1-21.9) ml/kg (P = 0.11). The liver blood flow as estimated by ICG clearance and Doppler ultrasound was not altered significantly after the treatment period (P = 0.07 and 0.77, respectively). CONCLUSIONS The liver volume increased by 19% in nine hyperthyroid patients during treatment with antithyroids. Antipyrine clearance was reduced by 16%, whereas liver blood flow, as estimated by ICG clearance and Doppler ultrasound examination of portal vein flow, was not significantly altered. A differential regulation of liver volume and oxidative metabolic capacity in hyperthyroidism was seen.

Abstract
We investigated prostanoid biogenesis in human colonic fibroblasts (CCD-18Co and 5 primary fibroblast cultures) and epithelial cell lines (NCM460, T84, HT-29, and LS 174T) and the effect of PGE2 on fibroblast morphology. Cytokine-stimulated PGE2 production was measured. PGH synthase-1 and -2 (PGHS-1 and -2) protein and mRNA expression were evaluated. Basal PGE2 levels were low in all cell types (0.15-6.47 ng/mg protein). Treatment for 24 h with interleukin-1beta (IL-1beta; 10 ng/ml) or tumor necrosis factor-alpha (50 ng/ml), respectively, elicited maximal 25- and 6-fold inductions of PGE2 synthesis in CCD-18Co cultures and similar results in primary fibroblast cultures; maximal inductions with IL-1beta in colonic epithelial cell lines were from zero to fivefold. Treatment of CCD-18Co fibroblasts with IL-1beta caused maximal 21- and 53-fold increases, respectively, in PGHS-2 protein and mRNA levels without altering PGHS-1 expression. PGE2 (0.1 micromol/l) elicited a dramatic shape change in selected fibroblasts. Colonic fibroblasts are potentially important as cytokine targets and a source of and target for colonic prostanoids in vivo.

Abstract
OBJECTIVE Some chemokine receptors have been shown to be co-receptors for human immunodeficiency virus (HIV-1). A 32 base pair deletion allele in the CC chemokine receptor 5 gene (CCR5 delta32 allele) affects both transmission of HIV-1 and acquired immunodeficiency syndrome (AIDS)-free survival. Chemokines are suggested to be critical for establishment of inflammatory processes in autoimmune diseases such as rheumatoid arthritis (RA). We hypothesized that the defective allele may modulate the inflammatory process in RA. METHODS Using polymerase chain reaction methods, we investigated the significance of the CCR5 delta32 allele in 163 Danish patients with RA and monitored clinical and paraclinical variables. RESULTS The gene frequency of the CCR5 delta32 allele (0.10) did not deviate significantly from healthy controls and from that reported in healthy Caucasian populations, nor did the distribution deviate from the Hardy-Weinberg predictions (131 wild type, 30 heterozygous, 2 homozygous for the deletion allele; p = 0.85). However, a significantly increased proportion of those carrying the deletion allele were negative for IgM rheumatoid factor (RF) compared to those homozygous for the normal allele (29 vs 9%; p = 0.007). The proportion of CCR5 delta32 allele carriers with swollen joints was decreased compared to those homozygous for the normal allele (35 vs 58%, respectively; p = 0.03), as was the duration of morning stiffness (median 0 vs 60 min, respectively; p = 0.0002). CONCLUSION The CCR5 delta32 allele seems to have some influence on RA variables including RF, which suggests that inhibition of chemokine receptors might be a potential target for disease modifying therapy in RA.
