    <div><p>Background and purpose</p><p>National dietary guidelines are intended to promote primary prevention of lifestyle-related diseases, but little is known about their effectiveness in prevention of stroke.</p><p>Methods</p><p>We used the Danish cohort Diet, Cancer and Health (n = 57 053) to investigate whether adherence to the Danish food-based dietary guidelines was associated with risk of stroke. Adherence was assessed by the Danish Dietary Guidelines Index, score 0 [no adherence] to 6 [complete adherence]. Cox proportional hazards models were used to estimate adjusted hazard ratios and 95% confidence intervals for stroke and subtypes of stroke in men and women separately.</p><p>Results</p><p>Incident stroke was determined in 1357 men and 900 women during follow-up (median 12.5 years and 13.0 years, respectively). A higher Danish Dietary Guidelines Index score was inversely associated with total stroke in men but not in women. In men, a high Index score (≥4) was also inversely associated with total ischemic stroke (hazard ratio 0.75, 95% confidence interval 0.65–0.86), large-artery atherosclerosis (hazard ratio 0.63, 95% confidence interval 0.44–0.92) and small artery occlusion (hazard ratio 0.68, 95% confidence interval 0.54–0.84) compared to a low Index score (<4). In women, inverse associations were found for total ischemic stroke (hazard ratio 0.84, 95% confidence interval 0.72–0.98) and intracerebral hemorrhage (hazard ratio 0.64, 95% confidence interval 0.43–0.96).</p><p>Conclusions</p><p>Our findings suggest that adherence to the Danish Dietary Guidelines is associated with a lower rate of stroke, and thus may be useful in primary prevention of disease.</p></div

    AbstractDiet is recognised as one modifiable lifestyle factor for ischaemic heart disease (IHD). We aimed at investigating the associations between adherence to the Danish Food-Based Dietary Guidelines (FBDG) indicated by a Dietary Quality Index (DQI) and selected cardiometabolic risk factors in a cross-sectional study with 219 Danish adult participants (59 %women; age 31–65years) with a minimum of one self-rated risk marker of IHD. Information regarding diet was obtained using web-based dietary assessment software and adherence to the Danish FBDG was expressed by a DQI calculated from 5 food and nutrient indicators (whole grain, fish, fruit and vegetables, energy from saturated fat and from added sugar). Background information, blood samples and anthropometrics were collected and blood pressure was measured. Linear regression analyses were used to evaluate the association between DQI and cardiometabolic risk factors. DQI was inversely associated with LDL:HDL ratio and TAG (−0·089 per unit; 95 % CI −0·177, −0·002 and −5 % per unit; 95 % CI −9, 0, respectively) and positively associated with HDL-cholesterol (0·047 mmol/l per unit; 95 % CI 0·007, 0·088). For men, DQI was inversely associated with BMI (−3 %per unit; 95 % CI −5, −1), trunk fat (−1 % per unit; 95 % CI −2, −1), high-sensitivity C-reactive protein (−30 % per unit; 95 % CI −41, −16 %), HbA1c(−0·09 % per unit; 95 % CI −0·14, −0·04), insulin (−13 % per unit; 95 % CI −19, −7) and homoeostatic model assessment-insulin resistance (−14 % per unit; 95 % CI −21, −7). In women, DQI was positively associated with systolic blood pressure (2·6 mmHg per unit; 95 % CI 0·6, 4·6). In conclusion, higher adherence to the current Danish FBDG was associated with a more beneficial cardiometabolic risk profile in a Danish adult population with a minimum of one self-rated risk factor for IHD.</jats:p

    <p>Abstract</p> <p>Background</p> <p>The xenobiotic transporters, Multidrug Resistance 1 <it>(MDR1/ABCB1) </it>and Breast Cancer Resistance Protein <it>(BCRP/ABCG2) </it>may restrict intestinal absorption of various carcinogens, including heterocyclic amines (HCA) and polycyclic aromatic hydrocarbons (PAH). Cyclooxygenase-2 (COX-2) derived prostaglandins promote gastrointestinal carcinogenesis, affecting angiogenesis, apoptosis, and invasiveness.</p> <p>The aim of this study was to investigate if polymorphisms in these genes were associated with risk of colorectal cancer (CRC), and to investigate possible interactions with lifestyle factors such as smoking, meat consumption, and NSAID use.</p> <p>Methods</p> <p>The following polymorphisms were analyzed; a synonymous <it>MDR1 </it>C3435T (rs1045642) in exon26, G-rs3789243-A in intron3, the functional <it>BCRP </it>C421A (rs2231142), the two <it>COX-2 </it>A-1195G (rs689466) and G-765C (rs20417) in the promoter region, and the <it>COX-2 </it>T8473C (rs5275) polymorphisms in the 3'-untranslated region. The polymorphisms were assessed together with lifestyle factors in a nested case-cohort study of 359 cases and a random cohort sample of 765 participants from the Danish prospective Diet, Cancer and Health study.</p> <p>Results</p> <p>Carriers of the variant allele of <it>MDR1 </it>intron 3 polymorphism were at 1.52-fold higher risk of CRC than homozygous wild type allele carriers (Incidence rate ratio (IRR) = 1.52, 95% Confidence Interval (CI): 1.12-2.06). Carriers of the variant allele of <it>MDR1 </it>C3435T exon 26 had a lower risk of CRC than homozygous C-allele carriers (IRR = 0.71 (CI:0.50-1.00)). There was interaction between these <it>MDR1 </it>polymorphisms and intake of red and processed meat in relation to CRC risk. Homozygous <it>MDR1 </it>C3435T C-allele carriers were at 8% increased risk pr 25 gram meat per day (CI: 1.00-1.16) whereas variant allele carriers were not at increased risk (p for interaction = 0.02). <it>COX-2 </it>and <it>BCRP </it>polymorphisms were not associated with CRC risk. There was interaction between NSAID use and <it>MDR1 </it>C3435T and COX-2 T8473C (p-values for interaction 0.001 and 0.04, respectively).</p> <p>Conclusion</p> <p>Two polymorphisms in <it>MDR1 </it>were associated with CRC risk and there was interaction between these polymorphisms and meat intake in relation to CRC risk. Our results suggest that <it>MDR1 </it>polymorphisms affect the relationship between meat and CRC risk.</p

    Pain Following Stroke: A Population-Based Follow-Up Study

    Background and Purpose: Chronic pain is increasingly recognized as a consequence of stroke. This study aimed to describe the prevalence and pain types of new onset chronic pain (‘‘novel pain’’) in patients with stroke compared with a randomly selected reference group from the general population and to identify factors associated with pain development in stroke patients. Methods: In a population-based follow-up design, development of chronic pain after stroke was assessed by a questionnaire sent to consecutive stroke patients, registered in a Danish national stroke database, two years after their stroke. A randomly selected sex- and age-matched reference group from the same catchment area received a similar questionnaire about development of new types of chronic pain in the same time period. A total of 608 stroke patients and 519 reference subjects were included in the study. Results: Development of novel pain was reported by 39.0 % of stroke patients and 28.9 % of reference subjects (OR 1.57, CI 1.21-2.04), and was associated with low age and depression in a multivariate model. Daily intake of pain medication for novel pain was reported by 15.3 % and 9.4 % of the stroke and reference population, respectively. Novel headache, shoulder pain, pain from increased muscle stiffness, and other types of novel pain were more common in stroke patients, whereas joint pain was equally common in the two groups. Conclusions: Development of chronic pain is more common in stroke patients compared with sex- and age-matched reference subjects. Evaluation of post-stroke pain should be part of stroke follow-up
