    • The European Collaborative Clinical Group (ECCG) has been surveying clinical management of sexually transmitted infections (STIs) in Europe since its inauguration in 2011. The ECCG is a network of nearly 130 STI specialists from 34 European countries who conduct questionnaire-based research across the European region. The research of ECCG focuses on providing data regarding clinical practice to inform European STI guideline development and revisions. The present paper describes the results of the 2018–19 ECCG survey regarding diagnosis and treatment of gonorrhoea in Europe.

  • Improvement of the quality and shelf life of wheat bread by fermentation with the antifungal strain Lactobacillus plantarum FST 1.7
  • 2007
  • Ingår i: Journal of Cereal Science. - London, United Kingdom : Elsevier. - 0733-5210 .- 1095-9963. ; 45:3, s. 309-318
  • Tidskriftsartikel (refereegranskat)abstract
    • Lactobacillus plantarum FST 1.7 was screened for in vitro antimicrobial activity and was shown to be active against spoilage moulds and bacteria. Isolation of antimicrobial compounds from cell-free supernatant identified lactic acid, phenyllactic acid and the two cyclic dipeptides cyclo ((L)-Leu-(L)-Pro) and cyclo ((L)-Phe-(L)-Pro) as the major components responsible for this activity. L. plantarum FST 1.7 was tested for the ability to produce the antifungal compounds during sourdough fermentation and to produce bread of good quality and increased shelf-life. A rheofermentometer was used to examine the gaseous release and development characteristics of the dough. A range of parameters was determined including pH, TTA and specific loaf volume. The results were compared with those obtained using Lactobacillus sanfranciscensis, a chemically acidified and a non-acidified dough. The quality of sourdough and bread produced using L. plantarum FST 1.7 was comparable to that obtained using common sourdough starters, e.g. L. sanfranciscensis. Sourdoughs and breads were evaluated for the ability to retard growth of Fusarium culmorum and Fusarium graminearum two fungi found on breads. Sourdough and bread produced with strain FST 1.7 showed consistent ability to retard the growth of both Fusarium species, thus indicating that L. plantarum FST 1.7 has also the potential to improve the shelf-life of wheat bread.

  • Whole-genome analysis of diverse Chlamydia trachomatis strains identifies phylogenetic relationships masked by current clinical typing
  • 2012
  • Ingår i: Nature Genetics. - : Nature Publishing Group. - 1061-4036 .- 1546-1718. ; 44:4, s. 413-419
  • Tidskriftsartikel (refereegranskat)abstract
    • Chlamydia trachomatis is responsible for both trachoma and sexually transmitted infections, causing substantial morbidity and economic cost globally. Despite this, our knowledge of its population and evolutionary genetics is limited. Here we present a detailed phylogeny based on whole-genome sequencing of representative strains of C. trachomatis from both trachoma and lymphogranuloma venereum (LGV) biovars from temporally and geographically diverse sources. Our analysis shows that predicting phylogenetic structure using ompA, which is traditionally used to classify Chlamydia, is misleading because extensive recombination in this region masks any true relationships present. We show that in many instances, ompA is a chimera that can be exchanged in part or as a whole both within and between biovars. We also provide evidence for exchange of, and recombination within, the cryptic plasmid, which is another key diagnostic target. We used our phylogenetic framework to show how genetic exchange has manifested itself in ocular, urogenital and LGV C. trachomatis strains, including the epidemic LGV serotype L2b.

  • Whole blood profiling of T-cell derived miRNA allows the development of prognostic models in inflammatory bowel disease
  • 2020
  • Ingår i: Journal of Crohn's & Colitis. - : Elsevier. - 1873-9946 .- 1876-4479. ; 14:12, s. 1724-1733
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: MicroRNAs (miRNAs) are cell-specific small non-coding RNAs that can regulate gene expression and have been implicated in Inflammatory Bowel Disease (IBD) pathogenesis. In our study, we define the cell-specific miRNA profiles and investigate its biomarker potential in IBD.METHODS: In a 2-stage prospective multi-centre case control study, Next Generation sequencing was performed on a discovery cohort of immunomagnetically separated leucocytes from 32 patients (9 CD, 14 UC, 8 healthy controls) and differentially expressed signals were validated in whole blood in 294 patients (97 UC, 98 CD, 98 non-IBD) using quantitative PCR. Correlations were analysed with phenotype, including need for early treatment escalation as a marker of progressive disease using Cox proportional hazards.RESULTS: In stage 1, each leucocyte subset (CD4+ and CD8+ T-cells and CD14+ monocytes) was analysed in IBD and controls. Three specific miRNAs differentiated IBD from controls in CD4+ T-cells, including miR-1307-3p (p=0.01), miR-3615 (p=0.02) and miR-4792 (p=0.01). In the extension cohort, in stage 2, miR-1307-3p was able to predict disease progression in IBD (HR 1.98, IQR:1.20-3.27;logrank p=1.80×10-3), in particular CD (HR 2.81; IQR: 1.11-3.53, p=6.50×10-4). Using blood-based multimarker miRNA models, the estimated chance of escalation in CD was 83% if 2 or more criteria were met and 90% for UC if 3 or more criteria are met.INTERPRETATION: We have identified and validated unique CD4+ T-cell miRNAs that are differentially regulated in IBD. These miRNAs may be able to predict treatment escalation and have the potential for clinical translation; further prospective evaluation is now indicated.

  • Composition and energy harvesting capacity of the gut microbiota : relationship to diet, obesity and time in mouse models
  • 2010
  • Ingår i: Gut. - : BMJ Publishing Group Ltd. - 0017-5749 .- 1468-3288. ; 59:12, s. 1635-42
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND AND AIMS: Increased efficiency of energy harvest, due to alterations in the gut microbiota (increased Firmicutes and decreased Bacteroidetes), has been implicated in obesity in mice and humans. However, a causal relationship is unproven and contributory variables include diet, genetics and age. Therefore, we explored the effect of a high-fat (HF) diet and genetically determined obesity (ob/ob) for changes in microbiota and energy harvesting capacity over time.METHODS: Seven-week-old male ob/ob mice were fed a low-fat diet and wild-type mice were fed either a low-fat diet or a HF-diet for 8 weeks (n=8/group). They were assessed at 7, 11 and 15 weeks of age for: fat and lean body mass (by NMR); faecal and caecal short-chain fatty acids (SCFA, by gas chromatography); faecal energy content (by bomb calorimetry) and microbial composition (by metagenomic pyrosequencing).RESULTS: A progressive increase in Firmicutes was confirmed in both HF-fed and ob/ob mice reaching statistical significance in the former, but this phylum was unchanged over time in the lean controls. Reductions in Bacteroidetes were also found in ob/ob mice. However, changes in the microbiota were dissociated from markers of energy harvest. Thus, although the faecal energy in the ob/ob mice was significantly decreased at 7 weeks, and caecal SCFA increased, these did not persist and faecal acetate diminished over time in both ob/ob and HF-fed mice, but not in lean controls. Furthermore, the proportion of the major phyla did not correlate with energy harvest markers.CONCLUSION: The relationship between the microbial composition and energy harvesting capacity is more complex than previously considered. While compositional changes in the faecal microbiota were confirmed, this was primarily a feature of high-fat feeding rather than genetically induced obesity. In addition, changes in the proportions of the major phyla were unrelated to markers of energy harvest which changed over time. The possibility of microbial adaptation to diet and time should be considered in future studies.

  • Is it more about mood than about sleep? An investigation into moderators and mediators of treatment response to cognitive behavioural therapy for insomnia
  • 2020
  • Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
    • Objectives/Introduction: Cognitive behavioural therapy for insomnia (CBT-I) is the first-line treatment for insomnia. Although 80% improve, 50% do not reach full remission. This study aimed to investigate the characteristics of patients who continue to report insomnia after CBT-I.Methods: Secondary analyses of a randomized controlled trial in Swedish primary care that included 165 patients with insomnia disorder. The intervention was seven sessions of nurse-administrated CBT-I as group treatment over ten weeks. The control condition was treatment as usual. Remission from insomnia was assessed by the yes-or-no question ‘Would you say that you have insomnia?’ at post-treatment.Results: At post-treatment, insomnia was reported by 95% in the control group (56 of 59), and by 57% in the intervention group (41 of 72). Patients who still reported insomnia after CBT-I had poorer mental health at baseline than those reporting remission (depressive symptoms, p = 0.006; psychological distress, p = 0.026; mental functioning, p = 0.048). They improved similarly to those reporting remission in sleep onset latency, time awake after sleep onset, sleep duration, sleep efficiency, awakenings, and sleep quality (p > 0.1, respectively), fatigue, psychological distress, depressive symptoms, and mental functioning (p > 0.2, respectively). They improved less in insomnia severity (p = 0.001), dysfunctional beliefs about sleep (p < 0.001), and use of hypnotics (p = 0.014). Change in depressive symptoms during treatments mediated between CBT-I and remission of insomnia in a model that took depressive symptoms and insomnia severity at baseline into account (direct effect, b = −2.58, CI −3.99, −1.16; indirect effect, b = −1.64, CI −3.38, −0.81). Depressive symptoms at baseline (- b = 0.32, p < 0.001) was a significant predictor of remission, but insomnia severity was not (- b = 0.08, p = 0.265).Conclusions: Although CBT-I improved sleep and daytime symptoms, the degree of depressive symptoms prior to treatment, as well as change in depressive symptoms during treatment, affected whether patients reported that they still suffered from insomnia or not. These findings highlight the importance of careful assessment of patients with insomnia in primary care and suggest tailored treatment for patients with pronounced depressive symptoms.

  • Adherence to the 2012 European gonorrhoea guideline in the WHO European Region according to the 2018-19 International Union against Sexually Transmitted Infections European Collaborative Clinical Group gonorrhoea survey
  • 2020
  • Ingår i: International Journal of STD and AIDS (London). - : Sage Publications. - 0956-4624 .- 1758-1052. ; 31:1, s. 69-76
  • Tidskriftsartikel (refereegranskat)abstract
    • Gonorrhoea is a major public health problem globally. Increasing incidence in many particularly developed countries and the emergence of resistance to the extended-spectrum cephalosporin ceftriaxone, the last option for empiric first-line monotherapy, are of serious concern. This paper evaluates the results of the 2018-19 International Union against Sexually Transmitted Infections European Collaborative Clinical Group survey on the diagnosis and treatment of gonorrhoea in Europe. Although high quality clinical care was reported in many European settings, in several countries the testing, diagnostics, antimicrobial treatment, and follow-up of gonorrhoea patients were evidently suboptimal. Increased adherence to evidence-based European and/or nationally-adapted management guidelines is essential in controlling the increasing incidence of gonorrhoea in many European settings and the spread of ceftriaxone-resistant, multidrug-resistant, and extensively drug-resistant gonorrhoea.
