- BACKGROUND AND AIMS: Vibration-controlled transient elastography (VCTE), point shear wave elastography (pSWE), two-dimensional shear wave elastography (2DSWE), magnetic resonance elastography (MRE), and magnetic resonance imaging (MRI) are proposed as non-invasive tests for patients with non-alcoholic fatty liver disease (NAFLD). This study evaluated their diagnostic accuracy for liver fibrosis and non-alcoholic steatohepatitis (NASH).METHODS: PubMED/MEDLINE, EMBASE and the Cochrane Library were searched for studies examining the diagnostic accuracy of these index tests against histology as the reference standard, in adult patients with NAFLD. Two authors independently screened and assessed methodological quality of studies and extracted data. Summary estimates of sensitivity, specificity and area under the curve (sAUC) were calculated for fibrosis stages and NASH, using a random effects bivariate logit-normal model.RESULTS: We included 82 studies (14,609 patients). Meta-analysis for diagnosing fibrosis stages was possible in 53 VCTE, 11 MRE, 12 pSWE and four 2DSWE studies, and for diagnosing NASH in four MRE studies. sAUC for diagnosis of significant fibrosis were: 0.83 for VCTE, 0.91 for MRE, 0.86 for pSWE and 0.75 for 2DSWE. sAUC for diagnosis of advanced fibrosis were: 0.85 for VCTE, 0.92 for MRE, 0.89 for pSWE and 0.72 for 2DSWE. sAUC for diagnosis of cirrhosis were: 0.89 for VCTE, 0.90 for MRE, 0.90 for pSWE and 0.88 for 2DSWE. MRE had sAUC of 0.83 for diagnosis of NASH. Three (4%) studies reported intention-to-diagnose analyses and 15 (18%) studies reported diagnostic accuracy against pre-specified cut-offs.CONCLUSIONS: When elastography index tests are acquired successfully, they have acceptable diagnostic accuracy for advanced fibrosis and cirrhosis. The potential clinical impact of these index tests cannot be assessed fully as intention-to-diagnose analyses and validation of pre-specified thresholds are lacking.LAY SUMMARY: Non-invasive tests that measure liver stiffness or use magnetic resonance imaging (MRI) have been suggested as alternatives to liver biopsy in assessing the severity of liver scarring (fibrosis) and fatty inflammation (steatohepatitis) in patients with non-alcoholic fatty liver disease (NAFLD). In this study, we summarise the results of previously published studies on how accurately these non-invasive tests can diagnose liver fibrosis and inflammation, using liver biopsy as the reference. We found that some techniques that measure liver stiffness had a good performance for the diagnosis of severe liver scarring.

- Studies have shown that probiotics can decrease the symptoms of respiratory tract infections as well as increase antibody responses following certain vaccinations. We examined the effect of probiotic supplementation on anti-SARS-CoV-2 specific antibody responses upon SARS-CoV-2 infection as well as after COVID-19 vaccination. In this randomized, triple-blinded, placebo-controlled intervention study with a parallel design, 159 healthy adults without prior SARS-CoV-2 infection or COVID-19 vaccination and any known risk factors for severe COVID-19 were randomly allocated into two study arms. The active treatment arm consumed a probiotic product containing a minimum of 1 × 108 colony-forming units of Limosilactobacillus reuteri DSM 17938 + 10 μg vitamin D3 twice daily for 6 months. The placebo arm consumed identical tablets containing only 10 μg vitamin D3. Anti-SARS-CoV-2 specific antibodies and virus neutralizing antibody titers were analyzed from blood samples collected at baseline, after 3 months, and after 6 months. Differences in serum antibody titers between the two study arms were tested with independent t-test using log-transformed values. In the intention-to-treat (ITT) analysis, SARS-CoV-2 infected individuals in the active treatment arm (n = 6) tended to have higher serum anti-spike IgG (609 [168-1480] BAU/ml vs 111 [36.1-1210] BAU/ml, p = 0.080) and anti-receptor binding domain (RBD) IgG (928 [212-3449] BAU/ml vs (83.7 [22.8-2094] BAU/ml, p = 0.066) levels than individuals in the placebo arm (n = 6). Considering individuals who were fully vaccinated with mRNA-based COVID-19 vaccines, the active treatment arm (n = 10) exhibited significantly higher serum levels of anti-RBD IgA (135 [32.9-976] BAU/ml vs 61.3 [26.7-97.1] BAU/ml, p = 0.036) than the placebo arm (n = 7) >28 days postvaccination. Supplementation with specific probiotics might improve the long-term efficacy of mRNA-based COVID-19 vaccines via enhanced IgA response.

- Background Faecal microbiota transplantation or transfer (FMT) aims at replacing or reinforcing the gut microbiota of a patient with the microbiota from a healthy donor. Not many controlled or randomised studies have been published evaluating the use of FMT for other diseases than Clostridium difficile infection, making it difficult for clinicians to decide on a suitable indication. To provide an expert consensus on current clinical indications, applications and methodological aspects of FMT. Well-acknowledged experts from various countries in Europe have contributed to this article. After literature review, consensus has been achieved by repetitive circulation of the statements and the full manuscript among all authors with intermittent adaptation to comments (using a modified Delphi process). Levels of evidence and agreement were rated according to the GRADE system. Consensus was defined a priori as agreement by at least 75% of the authors. Key recommendations include the use of FMT in recurrent C. difficile infection characterised by at least two previous standard treatments without persistent cure, as well as its consideration in severe and severe-complicated C. difficile infection as an alternative to total colectomy in case of early failure of antimicrobial therapy. FMT in inflammatory bowel diseases (IBD), irritable bowel syndrome (IBS) and metabolic syndrome should only be performed in research settings. Faecal microbiota transplantation or transfer is a promising treatment for a variety of diseases in which the intestinal microbiota is disturbed. For indications other than C. difficile infection, more evidence is needed before more concrete recommendations can be made.

Tidskriftsartikel (refereegranskat)abstract
- Healthy diet interventions have been shown to improve depressive symptoms, but thereis a need for randomized controlled trials (RCTs) that are double blind and investigate biologicalmechanisms. The primary objectives of this randomized controlled pilot trial were to test thepalatability of the meals and the acceptability of the intervention in preparation for an 8-week RCTin the future, which will investigate whether a healthy Nordic diet improves depressive symptomsin individuals with major depressive disorder, and associated biological mechanisms. Depressed(n = 10) and non-depressed (n = 6) women and men were randomized to receive either a healthyNordic diet (ND) or a control diet (CD) for 8 days. Participants were blinded to their diet allocationand the study hypotheses. Health questionnaires were completed before and after the interventionand, throughout the study, questionnaires assessed participants’ liking for the meals, their sensoryproperties, adherence, and open-ended feedback. In the ND group, 75% of participants consumedonly the provided foods, as instructed, compared to 50% of CD participants. The meals of both diets,on average, received good ratings for liking and sensory properties, though the ND ratings weresomewhat higher. Overall, results were positive and informative, indicating that the planned RCTwill be feasible and well-accepted, with some proposed modifications.

Forskningsöversikt (refereegranskat)abstract
- Objectives: This study aimed to narratively summarize the literature reporting on the effect of teamwork and communication training interventions on culture and patient safety in emergency department (ED) settings.Methods: We searched PubMed, EMBASE, Psych Info CINAHL, Cochrane, Science Citation Inc, the Web of Science, and Educational Resources Information Centre for peer-reviewed journal articles published from January 1, 1988, to June 8, 2018, that assessed teamwork and communication interventions focusing on how they influence patient safety in the ED. One additional search update was performed in July 2019.Results: Sixteen studies were included from 8700 screened publications. The studies' design, interventions, and evaluation methods varied widely. The most impactful ED training interventions were End-of-Course Critique, Team Strategies and Tools to Enhance Performance and Patient Safety (TeamSTEPPS), and crisis resource management (CRM)-based training. Crisis resource management and TeamSTEPPS CRM-based training curriculum were used in most of the studies. Multiple tools, including the Kirkpatrick evaluation model, the Agency for Healthcare Research and Quality Hospital Survey on Patient Safety Culture, the TeamSTEPPS Teamwork Attitudes Questionnaire, the Safety Attitudes Questionnaire, and the Communication and Teamwork Skills Assessment, were used to assess the impact of such interventions. Improvements in one of the domains of safety culture and related domains were found in all studies. Four empirical studies established improvements in patient health outcomes that occurred after simulation CRM training (Kirkpatrick 4), but there was no effect on mortality.Conclusions: Overall, teamwork and communication training interventions improve the safety culture in ED settings and may positively affect patient outcome. The implementation of safety culture programs may be considered to reduce incidence of medical errors and adverse events.

- The effect of dietary fibres on intestinal barrier function has not been well studied, especially in the elderly. We aimed to investigate the potential of the dietary fibres oat beta-glucan and wheat arabinoxylan to strengthen the intestinal barrier function and counteract acute non-steroid anti-inflammatory drug (indomethacin)-induced hyperpermeability in the elderly. A general population of elderly subjects (>= 65 years,n= 49) was randomised to a daily supplementation (12g/day) of oat beta-glucan, arabinoxylan or placebo (maltodextrin) for six weeks. The primary outcome was change in acute indomethacin-induced intestinal permeability from baseline, assessed by an in vivo multi-sugar permeability test. Secondary outcomes were changes from baseline in: gut microbiota composition, systemic inflammatory status and self-reported health. Despite a majority of the study population (85%) showing a habitual fibre intake below the recommendation, no significant effects on acute indomethacin-induced intestinal hyperpermeability in vivo or gut microbiota composition were observed after six weeks intervention with either dietary fibre, compared to placebo.

- Background: Although the estimated contribution of genetic factors is high in bipolar disorder, environmental factors may also play a role. This Swedish register-based cohort study of men examined if physical and psychological characteristics in late adolescence, including factors previously linked with bipolar disorder (body mass index, asthma and allergy), are associated with subsequent bipolar disorder in adulthood. Unipolar depression and anxiety are analysed as additional outcomes to identify bipolar disorder-specific associations.Methods: A total of 213,693 men born between 1952 and 1956, who participated in compulsory military conscription assessments in late adolescence were followed up to 2009, excluding men with any psychiatric diagnoses at baseline. Cox regression estimated risk of bipolar disorder, depression and anxiety in adulthood associated with body mass index, asthma, allergy, muscular strength stress resilience and cognitive function in adolescence.Results: BMI, asthma and allergy were not associated with bipolar disorder. Higher grip strength, cognitive function and stress resilience were associated with a reduced risk of bipolar disorder and the other disease outcomes.Limitations: The sample consisted only of men; even though the characteristics in adolescence pre-dated disease onset, they may have been the consequence of prodromal disease.Conclusions: Associations with body mass index and asthma found by previous studies may be consequences of bipolar disorder or its treatment rather than risk factors. Inverse associations with all the outcome diagnoses for stress resilience, muscular strength and cognitive function may reflect general risks for these psychiatric disorders or intermediary factors.
