- Carotid artery intima media thickness (cIMT) and carotid plaque are measures of subclinical atherosclerosis associated with ischemic stroke and coronary heart disease (CHD). Here, we undertake meta-analyses of genome-wide association studies (GWAS) in 71,128 individuals for cIMT, and 48,434 individuals for carotid plaque traits. We identify eight novel susceptibility loci for cIMT, one independent association at the previously-identified PINX1 locus, and one novel locus for carotid plaque. Colocalization analysis with nearby vascular expression quantitative loci (cis-eQTLs) derived from arterial wall and metabolic tissues obtained from patients with CHD identifies candidate genes at two potentially additional loci, ADAMTS9 and LOXL4. LD score regression reveals significant genetic correlations between cIMT and plaque traits, and both cIMT and plaque with CHD, any stroke subtype and ischemic stroke. Our study provides insights into genes and tissue-specific regulatory mechanisms linking atherosclerosis both to its functional genomic origins and its clinical consequences in humans.

- Purpose Yearly incidence of surgery for symptomatic lumbar disc herniation varies and is 29/100,000 in Sweden, 46/100,000 in Denmark and 58/100,000 in Norway. This variation was used to study whether differences in surgical incidence were associated with differences in preoperative patient characteristics as well as patient-reported outcomes. Methods Data from the national spine registers in Sweden, Denmark and Norway during 2011-2013 were pooled, and 9965 individuals, aged 18-65 years, of which 6468 had one-year follow-up data, were included in the study. Both absolute and case-mix-adjusted comparisons of the primary outcome Oswestry Disability Index (ODI) and the secondary outcomes EQ-5D-3L, and Numerical Rating Scale (NRS) for leg and back pain were performed. Case-mix adjustment was done for baseline age, sex, BMI, smoking, co-morbidity, duration of leg pain and preoperative value of the dependent variable. Results Mean improvement in the outcome variables exceeded previously described minimal clinical important change in all countries. Mean (95% CI) final scores of ODI were 18 (17-18), 19 (18-20) and 15 (15-16) in Sweden, Denmark and Norway, respectively. Corresponding results of EQ-5D-3L were 0.74 (0.73-0.75), 0.73 (0.72-0.75) and 0.75 (0.74-0.76). Results of NRS leg and back pain behaved similarly. Case-mix adjustment did not alter the findings substantially. Conclusion We found no clear association between incidence of surgery for lumbar disc herniation and preoperative patient characteristics as well as outcome, and the differences between the countries were lower than the minimal clinical important difference in all outcomes.

- Purpose To evaluate the outcome of degenerative lumbar spine surgery in a credible way, patient-reported outcome measures (PROMs) should be assessed after an adequate follow-up period. Most authors/journals consider a follow-up period of less than two years to be too short. The purpose of this study was to explore the possibility of restricting follow-up to one year. Methods Adult patients operated between 1998 and 2017 were retrieved from Swespine (Lumbar Disc Herniation n = 31,314, Lumbar Spinal Stenosis n = 53,043 and Degenerative Disc Disease n = 14,375). The proportion reaching the minimal important change (MIC) in Visual Analogue Scale for pain (VAS(BACK/LEG)), Oswestry Disability Index (ODI) and the quality-of-life measure EQ-5D(INDEX) at 1 and 2 years, respectively, was calculated. The single-item questions such as Global Assessment (GA(BACK/LEG)) and Satisfaction were analysed by the McNemar test. Threshold values for a successful outcome based on the final scores of each PROM at 1 and 2 years post-surgery were also defined. Results For all the three diagnostic groups, the differences in proportions reaching MIC of each PROM at 1 and 2 years were below 2%. Global Assessment and Satisfaction with outcome at one year remained at 2 years. There were no important differences of threshold values of treatment success based on final scores Conclusion No clinically important changes in PROMs appeared between 1 and 2 years after surgery for degenerative lumbar conditions, demonstrating that a follow-up period of 1 year as opposed to 2 years is sufficient in effectiveness studies if PROMs are to be used as outcome variables.

- OBJECTIVETo assess the prevalence of cerebral small-vessel disease (SVD) in subjects with type 1 diabetes compared with healthy control subjects and to characterize the diabetes-related factors associated with SVD.RESEARCH DESIGN AND METHODSThis substudy was cross-sectional in design and included 191 participants with type 1 diabetes and median age 40.0 years (interquartile range 33.0-45.1) and 30 healthy age- and sex-matched control subjects. All participants underwent clinical investigation and brain MRIs, assessed for cerebral SVD.RESULTSCerebral SVD was more common in participants with type 1 diabetes than in healthy control subjects: any marker 35% vs. 10% (P = 0.005), cerebral microbleeds (CMBs) 24% vs. 3.3% (P = 0.008), white matter hyperintensities 17% vs. 6.7% (P = 0.182), and lacunes 2.1% vs. 0% (P = 1.000). Presence of CMBs was independently associated with systolic blood pressure (odds ratio 1.03 [95% CI 1.00-1.05], P = 0.035).CONCLUSIONSCerebral SVD, CMBs in particular, is more common in young people with type 1 diabetes compared with healthy control subjects.
