- BACKGROUND: Epstein-Barr virus (EBV) and Human herpesvirus 6A (HHV-6A) are associated with increased risk of multiple sclerosis (MS). Conversely, infection with Cytomegalovirus (CMV) has been suggested to reduce the risk of MS but supporting data from presymptomatic studies are lacking. Here, we sought to increase the understanding of CMV in MS aetiology.METHODS: We performed a nested case-control study with presymptomatically collected blood samples identified through cross-linkage of MS registries and Swedish biobanks. Serological antibody response against CMV, EBV and HHV-6A was determined using a bead-based multiplex assay. Odds ratio (OR) with 95 % confidence intervals (CI) for CMV seropositivity as risk factor for MS was calculated by conditional logistic regression and adjusted for EBV and HHV-6A seropositivity. Potential interactions on the additive scale were analysed by calculating attributable proportion due to interaction (AP).RESULTS: Serum samples from 670 pairs of matched cases and controls were included. CMV seropositivity was associated with a reduced risk for MS (OR = 0.70, 95% CI 0.56-0.88, p = 0.003). Statistical interactions on the additive scale were observed between seronegativity for CMV and seropositivity against HHV-6A (AP 0.34, 95% CI 0.06-0.61) and EBV antigen EBNA-1 (amino acid 385-420) at age 20-39 years (AP 0.37, 95% CI 0.09-0.65).CONCLUSIONS: CMV seropositivity is associated with a decreased risk for MS. The protective role for CMV infection in MS aetiology is further supported by the interactions between CMV seronegativity and EBV and HHV-6A seropositivity.

- Objective Generic substitution has contributed to economic savings but switching products may affect patient adherence, particularly among those using multiple medications. The aim was to analyse if use of multiple medications influenced the association between switching products and refill adherence to angiotensin-converting-enzyme (ACE) inhibitors in Sweden. New users of ACE-inhibitors, starting between 1 July 2006 and 30 June 2007, were identified in the Swedish Prescribed Drug Register. Refill adherence was assessed using the continuous measure of medication acquisition (CMA) and analysed with linear regression and analysis of covariance. The study population included 42735 individuals whereof 51.2% were exposed to switching ACE-inhibitor and 39.6% used multiple medications. Refill adherence was higher among those exposed to switching products than those not, but did not vary depending on the use of multiple medications or among those not. Refill adherence varied with age, educational level, household income, country of birth, previous hospitalisation and previous cardiovascular diagnosis. The results indicate a positive association between refill adherence and switching products, mainly due to generic substitution, among new users of ACE-inhibitors in Sweden. This association was independent of use of multiple medications.

Tidskriftsartikel (refereegranskat)abstract
- Background:Several surgical procedures have been described in the reconstruction of long-gap esophageal atresia (LGEA). We reviewed the surgical methods used in children with LGEA in the Nordic countries over a 15-year period and the postoperative complications within the first postoperative year.Methods:Retrospective multicenter medical record review of all children born with Gross type A or B esophageal atresia between 01/01/2000 and 12/31/2014 reconstructed within their first year of life.Results:We included 71 children; 56 had Gross type A and 15 type B LGEA. Delayed primary anastomosis (DPA) was performed in 52.1% and an esophageal replacement procedure in 47.9%. Gastric pull-up (GPU) was the most frequent procedure (25.4%). The frequency of chromosomal abnormalities, congenital heart defects and other anomalies was significantly higher in patients who had a replacement procedure. The frequency of gastroesophageal reflux (GER) was significantly higher after DPA compared to esophageal replacement (p = 0.013). At 1-year follow-up the mean body weight was higher after DPA than after organ interposition (p = 0.043).Conclusion: DPA and esophageal replacement procedures were equally applied. Postoperative complications and follow-up were similar except for the development of GER and the body weight at 1-year follow-up. Long-term results should be investigated.Type of study:Treatment study.

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- SlutsatserTyp 1- och typ 2-diabetes Det finns ett samband mellan att äta medelhavskost och lägre risk att dö i förtid oavsett orsak (måttlig tillförlitlighet). Det finns ett samband mellan att äta en större andel2 fibrer eller baljväxter och lägre risk att dö i förtid oavsett orsak (måttlig tillförlitlighet). Det kan även finnas ett samband mellan att äta en större andel nötter och lägre risk att dö i förtid oavsett orsak (låg tillförlitlighet) samt lägre risk att insjukna i hjärt- och kärlsjukdom (låg tillförlitlighet). Det finns ett samband mellan att dricka mer2 kaffe och lägre risk att dö i förtid oavsett orsak och lägre risk att dö i förtid i kranskärlssjukdom (måttlig tillförlitlighet) samt möjligen en lägre risk att dö i förtid i hjärt- och kärlsjukdom (låg tillförlitlighet). Det råder generell brist på studier med lång uppföljningstid som jämför inverkan av olika slags kostråd på överlevnad, diabeteskomplikationer, diabetesremission3, livskvalitet och biverkningar. Tillförlitligheten av befintliga resultat är dessutom mycket låg för de flesta koster, kostbehandlingar, livsmedel och näringsämnen som har utvärderats. Effekter på hälsa och relaterade mått kan i dessa fall inte bedömas.2. Begreppet ”större andel” eller ”mer” avser inte nödvändigtvis att äta eller dricka mer totalt utan att öka mängden av ett visst livsmedel genom att byta ut annan mat eller dryck.Typ 2-diabetes Det kan finnas ett samband mellan att äta en större andel mättat fett och högre risk för att dö i förtid av hjärt- och kärlsjukdom (låg tillförlitlighet). Det kan även finnas ett samband mellan att äta en större andel enkelomättat fett och lägre risk att dö i förtid oavsett orsak (låg tillförlitlighet). En behandling med en initial period av kraftigt minskat energiintag med hjälp av lågenergipulver (VLED) med efterföljande övergång till mat för viktstabilitet jämfört med vanlig kostbehandling har gynnsamma effekter på livskvalitet (enligt EQ-5D), långtidsblodsocker (HbA1c) och vikt upp till 12 månader (måttlig tillförlitlighet)4. Vidare kan metoder där VLED ingår ha gynnsamma effekter på diabetesremission5 och midjeomfång upp till 12 månader (låg tillförlitlighet) och långtidsblodsocker (HbA1c) upp till 24 månader (låg tillförlitlighet). Intensiv livsstilsbehandling därlågfettkost kombineras med fysisk aktivitet och minskat energiintag har gynnsamma effekter jämfört med vanlig kostbehandling på långtidsblodsocker (HbA1c), vikt, kroppsmasseindex (BMI), midjeomfång och vissa blodfetter upp till 12 månader (måttlig tillförlitlighet)3. Viktminskningen kan kvarstå upp till omkring 10 år (låg tillförlitlighet). Behandlingen kan leda till bättre fysisk livskvalitet upp till 8 år (låg tillförlitlighet) medan effektskillnaden i psykisk livskvalitet under samma tid kan vara obefintlig eller försumbar (låg tillförlitlighet). Jämförelsen påvisar ingen förändrad risk att dö i förtid oavsett orsak eller att dö eller insjukna av kardiovaskulära orsaker efter omkring 10 år (låg tillförlitlighet). I det hälsoekonomiska perspektivet är intensiv livsstilsbehandling mer resurskrävande än vanlig kostbehandling, och beräkningar visar små eller inga vinster i kvalitetsjusterade levnadsår (QALYs) på individnivå. Energirestriktion i samband med intensiv livsstilsbehandling med ketogen kost eller med högproteinkost (20 E%) i kombination med fysisk aktivitet jämfört med vanlig kostbehandling kan ge en viktminskning upp till 11 månader (låg tillförlitlighet) men det saknas studier som kan visa om vikten kan bibehållas på längre sikt. Det saknas studier som undersökt kliniskt viktiga utfall som dödlighet, kardiovaskulära sjukdomar, livskvalitet och diabetesremission.3. Gäller endast vid typ 2-diabetes.4. Utgår från individer med en medelkroppsvikt på cirka 100 kg och medel-HbA1c på 60 mmol/mol.5. Resultaten för utfallet diabetesremission (att uppnå normala blodsockervärden) gäller när en diabetesdiagnos sattes för mindre än 6 år sedan eller för mindre än 3 år sedan. Definitionen för diabetesremission var ett HbA1c på mindre än 48 mmol/mol och att samtidigt vara fri från blodsockersänkande läkemedel.Graviditetsdiabetes Det saknas studier om kost vid graviditetsdiabetes med tillräcklig tillförlitlighet för att kunna bedöma effekterna.

Forskningsöversikt (refereegranskat)abstract
- Background: The surgical repair of long-gap esophageal atresia (LGEA) is still a challenge and there is no consensus on the preferred method of reconstruction. We performed a systematic review of the surgical treatment of LGEA Gross type A and B with the primary aim to compare the postoperative complications related to the different methods within the first postoperative year.Methods: Systematic literature review on the surgical repair of LGEA Gross type A and B within the first year of life published from January 01, 1996 to November 01, 2016.Results: We included 57 artides involving a total of 326 patients of whom 289 had a Gross type A LGEA. Delayed primary anastomosis (DPA) was the most applied surgical method (68.4%) in both types, followed by gastric pull-up (GPU) (83%). Anastomotic stricture (53.7%), gastro-esophageal reflux (GER) (32.2%) and anastomotic leakage (22.7%) were the most common postoperative complications, with stricture and GER occurring more often after DPA (61.9% and 40.8% respectively) compared to other methods (p < 0.001).Conclusion: The majority of patients in this review were managed by DPA and postoperative complications were common despite the surgical method, with anastomotic stricture and GER being most common after DPA.

Tidskriftsartikel (refereegranskat)abstract
- Objective: Foster family care is associated with adverse short- and long-term consequences for the child. A systematic review was conducted on interventions for foster children and foster careers. Method: A comprehensive search process was used to find eligible interventions evaluated in randomized controlled trials or quasi-experimental studies. The quality of studies was assessed with GRADE, and effects were synthesized using meta-analytic methods. Results: In all, 28 publications of 18 interventions, including 5,357 children, were identified. Only three specific interventions had sufficient confidence of evidence. No study had examined tools for foster parent selection nor had evaluated preservice programs related to outcomes. Discussion: These analyses provide new insights and hope into the field of systematic interventions in foster care. The overall results indicate that it is possible to improve eight outcomes but cannot point out which programs are superior. Ethically, social care organizations should systematically collect knowledge about effects and side effects.

Forskningsöversikt (refereegranskat)abstract
- Aim: Decades of research confirm that children and adolescents in out‐of‐home care (foster family, residential care) have much greater health care needs than their peers. A systematic literature review was conducted to evaluate organisational health care models for this vulnerable group.Methods: A systematic literature search was undertaken of the following data‐bases: Academic Search Elite, CENTRAL, Cochrane Database of Systematic Reviews, Cinahl, DARE, ERIC, HTA, PsycInfo, Psychology and Behavioural Sciences Collection, PubMed, SocIndex. Randomised and non‐randomised controlled trials were to be included. Two pairs of reviewers independently assessed abstracts of the identified published papers. Abstracts meeting the inclusion criteria were ordered in full text. Each article was reviewed independently, by pairs of reviewers. A joint assessment was made based on the inclusion criteria and relevance. Cases of disagreement were resolved by consensus discussion.Results: No study with low or medium risk of bias was identified.Conclusion: In the absence of studies of acceptable quality, it is not possible to assess the impact of organisational models intended to ensure adequate health and dental care for children and adolescents in out‐of‐home care. Therefore, well‐designed follow‐up studies should be conducted following the implementation of such models.

Tidskriftsartikel (refereegranskat)abstract
- We present a novel animal model for rheumatoid arthritis induced with a well defined synthetic adjuvant oil, pristane. Two weeks after a single intradermal injection of 150 microliters of pristane, the rats developed severe and chronic arthritis. The inflammation was restricted to the joints and involved pannus formation, major histocompatibility complex (MHC) class II expression, and T lymphocyte infiltration. The initial development as well as the chronic stage of pristane-induced arthritis was ameliorated by treatment with antibodies to the alpha beta-T-cell receptor showing that the disease is T cell dependent. Increased levels of interleukin in serum was seen after pristane injection but not during the chronic stage of arthritis. Joint erosions were accompanied by elevated serum levels of cartilage oligomeric matrix protein. Comparison of MHC congenic LEW strains showed that the severity and chronicity of arthritis varied among the different MHC haplotypes. Rats with RT1f haplotype showed a significantly higher susceptibility to pristane-induced arthritis. A strong influence of non-MHC genes was also suggested by the variability of arthritis susceptibility among different strains with the same MHC haplotype; the most susceptible background was the DA and the least susceptible was the E3. Arthritis induced with a well defined nonimmunogenic adjuvant, with a disease course that closely resembles that of rheumatoid arthritis, makes a suitable animal model for future studies of the pathology and genetics of rheumatoid arthritis
