- It is becoming increasingly evident that single-locus effects cannot explain complex multifactorial human diseases like cancer. We applied the multi-factor dimensionality reduction (MDR) method to a large cohort study on gene-environment and gene-gene interactions. The study (case-control nested in the EPIC cohort) was established to investigate molecular changes and genetic susceptibility in relation to air pollution and environmental tobacco smoke (ETS) in non-smokers. We have analyzed 757 controls and 409 cases with bladder cancer (n = 124), lung cancer (n = 116) and myeloid leukemia (n = 169). Thirty-six gene variants (DNA repair and metabolic genes) and three environmental exposure variables (measures of air pollution and ETS at home and at work) were analyzed. Interactions were assessed by prediction error percentage and cross-validation consistency (CVC) frequency. For lung cancer, the best model was given by a significant gene-environment association between the base excision repair (BER) XRCC1-Arg399Gln polymorphism, the double-strand break repair (DSBR) BRCA2-Asn372His polymorphism and the exposure variable 'distance from heavy traffic road', an indirect and robust indicator of air pollution (mean prediction error of 26%, P < 0.001, mean CVC of 6.60, P = 0.02). For bladder cancer, we found a significant 4-loci association between the BER APE1-Asp148Glu polymorphism, the DSBR RAD52-3'-untranslated region (3'-UTR) polymorphism and the metabolic gene polymorphisms COMT-Val158Met and MTHFR-677C > T (mean prediction error of 22%, P < 0.001, mean CVC consistency of 7.40, P < 0.037). For leukemia, a 3-loci model including RAD52-2259C > T, MnSOD-Ala9Val and CYP1A1-Ile462Val had a minimum prediction error of 31% (P < 0.001) and a maximum CVC of 4.40 (P = 0.086). The MDR method seems promising, because it provides a limited number of statistically stable interactions; however, the biological interpretation remains to be understood.

- Objective: To describe-and compare the consumption of total fish (marine foods) and the fish sub-groups - white fish, fatty fish, very fatty fish, fish products and crustacea, in participants from the European Investigation into. Cancer and Nutrition (EPIC) study. Design: Cross-sectional analysis of dietary intake using a computerised standardised 24-hour recall interview. Crude means, means and standard errors adjusted by age, season and day of the week were calculated, stratified by centre and gender, Setting: Twenty-seven redefined centres in the 10 European countries participating in the EPIC study. Subjects.. In total, 35 955 subjects (13 031 men and 22 924 women), aged 35-74 years, selected from the main EPIC cohort. Results: A six- to sevenfold variation in total fish consumption exists in women and men, between the lowest consumption in Germany and the highest in Spain. Overall, white fish represented 49% and 45% of the intake of total fish in women and men, respectively, with the greatest consumption in centres in Spain and Greece and the least in the German and Dutch centres. Consumption of fatty fish reflected that of total fish. However, the greatest intake of very fatty fish was in the coastal areas of northern Europe (Denmark, Sweden and Norway) and in Germany. Consumption of fish products was greater in northern than in southern Europe, with white fish products predominating in centres in France, Italy, Spain, The Netherlands and Norway. Intake of roe and roe products was low. The highest consumption of crustacea was found in the French, Spanish and Italian centres. The number of fish types consumed was greater in southern than in northern Europe. The greatest variability in consumption by day of the week-was found in the countries with - the lowest fish intake. Conclusions: Throughout Europe, substantial geographic variation exists in total fish intake, fish sub-groups and the number of types consumed. Day-to-day variability in consumption is also high.

Th1 and Th17 responses to Helicobacter pylori in Bangladeshi infants, children and adults
- 2014

Tidskriftsartikel (refereegranskat)abstract
- Both Th1 and Th17 cells are important components of the immune response to Helicobacter pylori (Hp) in adults, but less is known about T cell responses to Hp during early childhood, when the infection is often acquired. We investigated Th1 and Th17 type responses to Hp in adults, children and infants in Bangladesh, where Hp is highly endemic. IL-17 and IFN-γ mRNA levels in gastric biopsies from Hp-infected Bangladeshi adults were analyzed and compared to levels in infected and uninfected Swedish controls. Since biopsies could not be collected from infants and children, cytokine responses in Bangladeshi infants (6-12 months), children (3-5 years) and adults (>19 years) were instead compared by stimulating peripheral blood mononuclear cells (PBMCs) with a Hp membrane preparation (MP) and analyzing culture supernatants by ELISA and cytometric bead array. We found significantly higher expression of IL-17 and IFN-γ mRNA in gastric mucosa of Hpinfected Bangladeshi and Swedish adults compared to uninfected Swedish controls. PBMCs from all age groups produced IL-17 and IFN-γ after MP stimulation, but little Th2 cytokines. IL-17 and IFN-γ were primarily produced by CD4+ T cells, since CD4 + T cell depleted PBMCs produced reduced amounts of these cytokines. Infant cells produced significantly more IL-17, but similar levels of IFN-γ, compared to adult cells after MP stimulation. In contrast, polyclonal stimulation induced lower levels IL-17 and IFN-γ in infant compared to adult PBMCs and CD4+ T cells. The strong IL-17 production in infants after MP stimulation was paralleled by significantly higher production of the IL-17 promoting cytokine IL-1β from infant compared to adult PBMCs and monocytes. In conclusion, these results show that T cells can produce high levels of IL-17 and IFN-β in response to Hp from an early age and indicate a potential role for IL-1β in promoting Th17 responses to Hp during infancy. © 2014 Bhuiyan et al.

- Cell-free circulating DNA isolated from the plasma of individuals with cancer has been shown to harbor cancer-associated changes in DNA methylation, and thus it represents an attractive target for biomarker discovery. However, the reliable detection of DNA methylation changes in body fluids has proven to be technically challenging. Here we describe a novel combination of methods that allows quantitative and sensitive detection of DNA methylation in minute amounts of DNA present in body fluids (quantitative Methylation Analysis of Minute DNA amounts after whole Bisulfitome Amplification, qMAMBA). This method involves genome-wide amplification of bisulphite-modified DNA template followed by quantitative methylation detection using pyrosequencing and allows analysis of multiple genes from a small amount of starting DNA. To validate our method we used qMAMBA assays for four genes and LINE1 repetitive sequences combined with plasma DNA samples as a model system. qMAMBA offered high efficacy in the analysis of methylation levels and patterns in plasma samples with extremely small amounts of DNA and low concentrations of methylated alleles. Therefore, qMAMBA will facilitate methylation studies aiming to discover epigenetic biomarkers, and should prove particularly valuable in profiling a large sample series of body fluids from molecular epidemiology studies as well as in tracking disease in early diagnostics.

- OBJECTIVE: To determine the effectiveness and cost-effectiveness of a range of strategies based on conventional clinical information and novel circulating biomarkers for prioritising patients with stable angina awaiting coronary artery bypass grafting (CABG).DATA SOURCES: MEDLINE and EMBASE were searched from 1966 until 30 November 2008.REVIEW METHODS: We carried out systematic reviews and meta-analyses of literature-based estimates of the prognostic effects of circulating biomarkers in stable coronary disease. We assessed five routinely measured biomarkers and the eight emerging (i.e. not currently routinely measured) biomarkers recommended by the European Society of Cardiology Angina guidelines. The cost-effectiveness of prioritising patients on the waiting list for CABG using circulating biomarkers was compared against a range of alternative formal approaches to prioritisation as well as no formal prioritisation. A decision-analytic model was developed to synthesise data on a range of effectiveness, resource use and value parameters necessary to determine cost-effectiveness. A total of seven strategies was evaluated in the final model.RESULTS: We included 390 reports of biomarker effects in our review. The quality of individual study reports was variable, with evidence of small study (publication) bias and incomplete adjustment for simple clinical information such as age, sex, smoking, diabetes and obesity. The risk of cardiovascular events while on the waiting list for CABG was 3 per 10,000 patients per day within the first 90 days (184 events in 9935 patients with a mean of 59 days at risk). Risk factors associated with an increased risk, and included in the basic risk equation, were age, diabetes, heart failure, previous myocardial infarction and involvement of the left main coronary artery or three-vessel disease. The optimal strategy in terms of cost-effectiveness considerations was a prioritisation strategy employing biomarker information. Evaluating shorter maximum waiting times did not alter the conclusion that a prioritisation strategy with a risk score using estimated glomerular filtration rate (eGFR) was cost-effective. These results were robust to most alternative scenarios investigating other sources of uncertainty. However, the cost-effectiveness of the strategy using a risk score with both eGFR and C-reactive protein (CRP) was potentially sensitive to the cost of the CRP test itself (assumed to be 6 pounds in the base-case scenario).CONCLUSIONS: Formally employing more information in the prioritisation of patients awaiting CABG appears to be a cost-effective approach and may result in improved health outcomes. The most robust results relate to a strategy employing a risk score using conventional clinical information together with a single biomarker (eGFR). The additional prognostic information conferred by collecting the more costly novel circulating biomarker CRP, singly or in combination with other biomarkers, in terms of waiting list prioritisation is unlikely to be cost-effective.

The Future of Warheads, Armour and Ballistics

- In 1983 a “Grand Old Man” of Ballistic Science, Dr. Robert J. Eichelberger, wrote1 : ”Ballistic technology is generally considered a mature technology – as it should be after centuries of intensive attention of some of the finest scientific minds of the world.” He predicted that increased understanding of relevant physics and chemistry and development of mathematical techniques and computer models would be key elements in the future of ballistics and weapon system design. These predictions were very accurate! But to-day’s developments and those of the foreseeable future go beyond this. Warheads and ballistics – interior, exterior and terminal – are very dependent on the use and properties of energetic materials – propellants and explosives – for their functioning. New, potentially very powerful substances such as the N5+ and N5– ions and metallic hydrogen were created in labs. Air-breathing propulsion – ramjets etc. - and efficient use of the high combustion energy of some metals adds to the performance increase potential. Increased use of intelligence, computers, sensors and fuzing in weapons, munitions and armours has added another dimension to the efficiency achievable. New high-performance materials have also meant great increases in effects and protection potential. Developments possible in the next 20 years may have similar effect on warfare as the revolution in weapons, munitions and armour that occurred in the late 19th century. The statement that ”Ballistic technology is generally considered a mature technology” is no longer true. Any nation that will abstain from following the developments closely and exploiting their advances will run the risk both of having weapons, munitions and protection that prove inadequate and of making grave mis-investments.

- BACKGROUND: Morphine adversely impacts the action of oral adenosine diphosphate (ADP)-receptor blockers in ST-segment elevation myocardial infarction (STEMI) patients, and is possibly associated with differing patient characteristics. This retrospective analysis investigated whether interaction between morphine use and pre-percutaneous coronary intervention (pre-PCI) ST-segment elevation resolution in STEMI patients in the ATLANTIC study was associated with differences in patient characteristics and management.METHODS: ATLANTIC was an international, multicenter, randomized study of treatment in the acute ambulance/hospital setting where STEMI patients received ticagrelor 180 mg ± morphine. Patient characteristics, cardiovascular history, risk factors, management, and outcomes were recorded.RESULTS: Opioids (97.6% morphine) were used in 921 out of 1862 patients (49.5%). There were no significant differences in age, sex or cardiovascular history, but more morphine-treated patients had anterior myocardial infarction and left-main disease. Time from chest pain to electrocardiogram and ticagrelor loading was shorter with morphine (both p = 0.01) but not total ischemic time. Morphine-treated patients more frequently received glycoprotein IIb/IIIa inhibitors (p = 0.002), thromboaspiration and stent implantation (both p < 0.001). No significant difference between the two groups was found regarding pre-PCI ≥ 70% ST-segment elevation resolution, death, myocardial infarction, stroke, urgent revascularization and definitive acute stent thrombosis. More morphine-treated patients had an absence of pre-PCI Thrombolysis in Myocardial Infarction (TIMI) 3 flow (85.8% vs. 79.7%; p = 0.001) and more had TIMI major bleeding (1.1% vs. 0.1%; p = 0.02).CONCLUSIONS: Morphine-treatment was associated with increased GP IIb/IIIa inhibitor use, less pre-PCI TIMI 3 flow, and more bleeding. Judicious morphine use is advised with non-opioid analgesics preferred for non-severe acute pain.TRIAL REGISTRATION: clinicaltrials.gov identifier: NCT01347580.

- BACKGROUND The direct-acting platelet P2Y(12) receptor antagonist ticagrelor can reduce the incidence of major adverse cardiovascular events when administered at hospital admission to patients with ST-segment elevation myocardial infarction (STEMI). Whether prehospital administration of ticagrelor can improve coronary reperfusion and the clinical outcome is unknown. METHODS We conducted an international, multicenter, randomized, double-blind study involving 1862 patients with ongoing STEMI of less than 6 hours duration, comparing prehospital (in the ambulance) versus in-hospital (in the catheterization laboratory) treatment with ticagrelor. The coprimary end points were the proportion of patients who did not have a 70% or greater resolution of ST-segment elevation before percutaneous coronary intervention (PCI) and the proportion of patients who did not have Thrombolysis in Myocardial Infarction flow grade 3 in the infarct-related artery at initial angiography. Secondary end points included the rates of major adverse cardiovascular events and definite stent thrombosis at 30 days. RESULTS The median time from randomization to angiography was 48 minutes, and the median time difference between the two treatment strategies was 31 minutes. The two coprimary end points did not differ significantly between the prehospital and in-hospital groups. The absence of ST-segment elevation resolution of 70% or greater after PCI (a secondary end point) was reported for 42.5% and 47.5% of the patients, respectively. The rates of major adverse cardiovascular events did not differ significantly between the two study groups. The rates of definite stent thrombosis were lower in the prehospital group than in the in-hospital group (0% vs. 0.8% in the first 24 hours; 0.2% vs. 1.2% at 30 days). Rates of major bleeding events were low and virtually identical in the two groups, regardless of the bleeding definition used. CONCLUSIONS Prehospital administration of ticagrelor in patients with acute STEMI appeared to be safe but did not improve pre-PCI coronary reperfusion.

- Within the European Prospective Investigation into Cancer and Nutrition (EPIC), the authors examined the association of ethanol intake at recruitment (1,119 cases) and mean lifelong ethanol intake (887 cases) with lung cancer. Information on baseline and past alcohol consumption, lifetime tobacco smoking, diet, and the anthropometric characteristics of 478,590 participants was collected between 1992 and 2000. Cox proportional hazards regression was used to calculate multivariate-adjusted hazard ratios and 95% confidence intervals. Overall, neither ethanol intake at recruitment nor mean lifelong ethanol intake was significantly associated with lung cancer. However, moderate intake (5-14.9 g/day) at recruitment (hazard ratio (HR) = 0.76, 95% confidence interval (CI): 0.63, 0.90) and moderate mean lifelong intake (HR = 0.80, 95% CI: 0.66, 0.97) were associated with a lower lung cancer risk in comparison with low consumption (0.1-4.9 g/day). Compared with low intake, a high (>= 60 g/day) mean lifelong ethanol intake tended to be related to a higher risk of lung cancer (HR = 1.29, 95% CI: 0.93, 1.74), but high intake at recruitment was not. Although there was no overall association between ethanol intake and risk of lung cancer, the authors cannot rule out a lower risk for moderate consumption and a possibly increased risk for high lifelong consumption.

Affinity proteomics for systematic protein profiling of chromosome 21 gene products in human tissues
- 2003
-
Ingår i: Molecular & Cellular Proteomics. - 1535-9476 .- 1535-9484. ; 2, s. 405-
-
Tidskriftsartikel (refereegranskat)abstract
- Here we show that an affinity proteomics strategy using affinity-purified antibodies raised against recombinant human protein fragments can be used for chromosome-wide protein profiling. The approach is based on affinity reagents raised toward bioinformatics-designed protein epitope signature tags corresponding to unique regions of individual gene loci. The genes of human chromosome 21 identified by the genome efforts were investigated, and the success rates for de novo cloning, protein production, and antibody generation were 85, 76, and 56%, respectively. Using human tissue arrays, a systematic profiling of protein expression and subcellular localization was undertaken for the putative gene products. The results suggest that this affinity proteomics strategy can be used to produce a proteome atlas, describing distribution and expression of proteins in normal tissues as well as in common cancers and other forms of diseased tissues.

- Knowledge and application of human factors and ergonomics (HFE) has significant potential as auseful tool and solution provider in the development, design and implementation of safe, efficient and sustainable artefacts and systems. Yet, it seems that this HFE knowledge is not utilised to its full potential. In a world of competing financial and commercial priorities, HFE specialists have apparently not succeeded in selling the systems approach as a tool towards improved overall systems performance and human well-being.The present paper describes the strategic and practical workperformed by the Swedish Ergonomics and Human Factors Society (EHSS) to strengthen the quality of human factors and ergonomics knowledge and practice among various stakeholders in Sweden. EHSS view human factors and ergonomics as a systems and design oriented discipline that extends across all aspects of human activity. Beyond the traditional domains of specialization within the discipline, the physical, cognitive and organisational ergonomics, EHSS has identified three focus areas; visual ergonomics, voice ergonomics and ergonomics design for all.Practitioner Summary: This paper presents the strategic and practical work performed by the Swedish Ergonomics and Human Factors Society (EHSS) in order to strengthen the quality of human factors and ergonomics knowledge and practice in Sweden. EHSS has identified three focus areas for its strategic work: visual ergonomics, voice ergonomics and ergonomics design for all.

- Aims The objective of this study was to investigate if biofilms may be potential reservoirs for the waterborne pathogen enterotoxigenic Escherichia coli (ETEC) in household water in Dhaka, Bangladesh. Methods and Results Biofilms formed on submerged glass slides. Mature biofilms were found significantly more often on glass slides collected in the monsoon period between the two annual ETEC peaks in Bangladesh, that is, between May and August than the rest of the year (P < 0·03). Sixty-four per cent (49/77) of all biofilms analysed by quantitative real-time PCR were positive for ETEC. Significantly more ETEC-PCR positive biofilms were found during the epidemic peaks and during flooding periods than the rest of the year (P < 0·008). Planktonic ETEC was present in the household water during all seasons, but there was no correlation between presence or numbers of ETEC in water and the epidemic peaks. Conclusions We conclude that ETEC is continuously present in water and biofilms in household water reservoirs in Dhaka, which has a high prevalence of ETEC diarrhoea. The frequency of biofilms with ETEC was significantly associated (P < 0·008) with seasonal epidemic peaks of ETEC diarrhoea. Significance and impact of the study We show for the first time that enterotoxigenic Escherichia coli (ETEC), the causative agent of acute watery diarrhoea and travellers' diarrhoea is present in biofilms in household water tanks in Dhaka, Bangladesh.

- INTRODUCTION: There is a large inter-individual variation in response to clopidogrel treatment and previous studies have indicated higher risk of thrombotic events in patients with high residual platelet reactivity (HRPR), but the optimal time-point for testing is not established. The aim of this study was to investigate the optimal time-point for aggregometry testing and the risk of major adverse cardiac events associated with HRPR.METHOD AND RESULTS: We included 125 patients with ACS (73 with STEMI, and 71 received abciximab). The prevalence of HRPR varied substantially over time. The rate of HRPR in patients treated and not treated with abciximab were 43% vs 67% (p=0.01) before, 2% vs 23% (p=0.001) 6-8h after, 8% vs 9% (p=0.749) 3days after, and 23% vs 12% (p=0.138) 7-9 days after loading dose of clopidogrel. We found HRPR in 18% of the patients but only four ischemic events during 6months follow-up, with no significant difference between HRPR patients compared to the rest of the population. There were 3 TIMI major bleedings, all of which occurred in the low residual platelet reactivity (LRPR) group.CONCLUSION: There is a large variation in platelet reactivity over time, also depending on adjunctive therapy, which has a large impact on optimal time-point for assessment. We found HRPR in almost 1 in 5 patients, but very few MACE, and not significantly higher in HRPR patients. In a contemporary ACS population, with low risk for stent thrombosis, the predictive value of HRPR for ischemic events will probably be low.

- Background Among patients with STEMI in the ATLANTIC study, pre-hospital administration of ticagrelor improved post-PCI ST-segment resolution and 30-day stent thrombosis. We investigated whether this clinical benefit with pre-hospital ticagrelor differs by ischemic duration. Methods In a post hoc analysis we compared absence of ST-segment resolution post-PCI and stent thrombosis at 30 days between randomized treatment groups (pre-versus in-hospital ticagrelor) stratified by symptom onset to first medical contact (FMC) duration [amp;lt;= 1 hour (n = 773), amp;gt;1 to amp;lt;= 3 hours (n = 772), and amp;gt;3 hours (n = 311)], examining the interaction between randomized treatment strategy and duration of symptom onset to FMC for each outcome. Results Patients presenting later after symptom onset were older, more likely to be female, and have higher baseline risk. Patients with symptom onset to FMC amp;gt;3 hours had the greatest improvement in post-PCI ST-segment elevation resolution with pre-versus in-hospital ticagrelor (absolute risk difference: amp;lt;= 1 hour, 2.9% vs. amp;gt;1 to amp;lt;= 3 hours, 3.6% vs. amp;gt;3 hours, 12.2%; adjusted p for interaction = 0.13), while patients with shorter duration of ischemia had greater improvement in stent thrombosis at 30 days with pre-versus in-hospital ticagrelor (absolute risk difference: amp;lt;= 1 hour, 1.3% vs. amp;gt;1 hour to amp;lt;= 3hours, 0.7% vs. amp;gt;3 hours, 0.4%; adjusted p for interaction = 0.55). Symptom onset to active ticagrelor administration was independently associated with stent thrombosis at 30 days (adjusted OR 1.89 per 100 minute delay, 95% CI 1.20-2.97, P amp;lt; .01), but not post-PCI ST-segment resolution (P = .41). Conclusions The effect of pre-hospital ticagrelor to reduce stent thrombosis was most evident when given early within 3 hours after symptom onset, with delay in ticagrelor administration after symptom onset associated with higher rate of stent thrombosis. These findings re-emphasize the need for early ticagrelor administration in primary PCI treated STEMI patients.

- Background: Limited data are available concerning benefits and risks of early abciximab (EA) administration before primary percutaneous coronary intervention (PPCI) in elderly ST-segment elevation myocardial infarction (STEMI) patients. The objective of the study was to assess the impact of EA before PPCI in elderly (andgt;= 65 years) patients. Methods and results: We identified 545 patients andlt;65 years (354 with EA administration (andgt;30 min before PPCI), 191 late abciximab (LA)), and 541 patients andgt;= 65 years of age (373 EA, 168 LA) in the EUROTRANSFER Registry database. Elderly patients were more likely to have comorbidities, angiographic PCI complications, and bleeding events. EA promotes infarct-related artery patency before PPCI and improves myocardial reperfusion after PPCI in both age groups, but the risk of 30-day death (EA vs. LA: andlt;65 years, 2.0% vs. 1.6%; p = 0.999; andgt;= 65 years, 5.9% vs. 14.3%; p = 0.001) and 30-day death + reinfarction (EA vs. LA: andlt;65 years, 2.5% vs. 2.1%; p = 0.999; andgt;= 65 years, 7.5% vs. 17.3%; p = 0.001) was reduced in elderly patients only. There was no difference in bleedings, especially major bleedings requiring transfusion (EA vs. LA: patients andlt;65 years, 2.3% vs. 0%, p = 0.055; andgt;= 65 years, 2.4% vs. 3%; p = 0.448) between groups. Conclusions: Patients andgt;= 65 years of age have a substantially increased risk of angiographic PCI complications, death and bleeding events compared with their younger counterparts. Strategy of EA before PPCI improves reperfusion parameters and clinical outcome in elderly patients and is not associated with elevated risk of major bleeding.

- OBJECTIVE: To study whether physical activity is associated with reduced occurrence of asymptomatic leg atherosclerosis. DESIGN: Longitudinal and cross-sectional analyses of the population-based cohort "men born in 1914". METHODS: Comparison of the systolic ankle/arm pressure index (AAI) at age 68 in groups who were sedentary, performed some activity, and performed regular physical training at 55 and 68 years of age. RESULTS: At 55 years of age, 100 (27%) were sedentary, 209 (58%) reported some physical activity and 54 (15%) reported regular physical training. At 68 years, 194 men (53%) reported the same degree of physical activity, 127 (35%) reported a higher physical activity, and 42 (12%) reported lower physical activity. Physical activity at 55 years (p =0.03) and increased physical activity between 55 and 68 years (p =0.03) were both associated with higher AAI at 68 after adjusting for potential confounders. At 68 years, AAI was 0.89+/-0.21, 1.01+/-0.13 and 1.05+/-0.11, respectively, in men who were sedentary, reported some physical activity, and regular physical training (p =0.0002). This association remained significant after adjustments for potential confounders. CONCLUSIONS: regular physical activity is associated with reduced occurrence of asymptomatic leg atherosclerosis, even in men taking up exercise after age of 55.

- OBJECTIVE: Age adjusted incidence of myocardial infarction has been found to vary substantially between the residential areas of the city of Malmo. The objective of this study was to assess the extent to which major biological risk factors and socio-economic circumstances account for the differences in incidence of and mortality from myocardial infarction. DESIGN: Ecological study of risk factor prevalence and incidence and mortality from myocardial infarction. SETTING: Seventeen administrative areas in Malmo, Sweden. SUBJECTS: Assessment of risk factor prevalence was based on 28 466 men and women, ranging from 45 to 73 years old, who were recruited as participants in the Malmo Diet and Cancer study. Information on serum lipids was available in a random subsample of 5362 subjects. Information about socio-economic level of the residential area was based on statistics from the Malmo City Council and Statistics Sweden. MAIN OUTCOME MEASURES: Weighted least square regressions between prevalence of risk factors (i.e. smoking, hypertension, obesity, diabetes, hypercholesterolemia and hypertriglyceridemia), a myocardial infarction risk score, a socio-economic score and incidence and mortality from myocardial infarction. RESULTS: The risk factor prevalence and myocardial infarction incidence was highest in areas with low socio-economic level. Prevalence of smoking, obesity and hypertension was significantly associated with myocardial infarction incidence and mortality rates amongst men (all r > 0.60). Prevalence of smoking was significantly associated with incidence and mortality from myocardial infarction amongst women (r = 0.66 and r = 0.61, respectively). A myocardial infarction risk score based on four biological risk factors explained 40-60% of the intra-urban geographical variation in myocardial infarction incidence and mortality. The socio-economic score added a further 2-16% to the explained variance. CONCLUSION: In an urban population with similar access to medical care, well-known biological cardiovascular risk factors account for a substantial proportion of the intra-urban geographical variation of incidence of and mortality from myocardial infarction. The socio-economic circumstances further contribute to the intra-urban variation in disease.

- OBJECTIVE: New treatments have improved the prognosis for patients with acute myocardial infarction. However, studies on long-term survival are not unequivocally in favour of an improved long-term prognosis. This study aimed to analyse trends in 3-year survival in relation to sex, age and socioeconomic level of residential area. SETTING: The Malmo myocardial infarction register, Sweden. PARTICIPANTS: All men and women in the city who, between 1978 and 1995, were admitted for a first acute myocardial infarction (n = 11 226). MAIN OUTCOME MEASURES: Age-standardized 3-year survival rates. RESULTS: Both 28-day and 3-year survival rates improved markedly during the study period. Age-standardized 3-year survival (per 100 patients) amongst men and women who survived 28 days increased, between 1978-81 and 1991-95, from 64 to 78 in men and from 66 to 77 in women, an annual increase of 1.4% (95% CI = 1.1-1.7) and 1.2% (0.8-1.5), respectively. There were marked differences in survival between residential areas with different socioeconomic circumstances. The 3-year survival rates amongst men correlated significantly with the socioeconomic circumstances in the areas expressed in terms of a socioeconomic score (men: r = 0.60, n = 17, P = 0.01; women: r = 0.37, P = 0.15). Trends tended to be less favourable in deprived areas. CONCLUSION: Three-year survival after first myocardial infarction has continuously improved for men and women in all age groups. Prognosis was worse and trends tended to be less favourable for patients from deprived areas.

- BACKGROUND: In the ATLANTIC (Administration of Ticagrelor in the catheterization laboratory or in the Ambulance for New ST elevation myocardial Infarction to open the Coronary artery) trial the early use of aspirin, anticoagulation, and ticagrelor coupled with very short medical contact-to-balloon times represent good indicators of optimal treatment of ST-elevation myocardial infarction and an ideal setting to explore which factors may influence coronary reperfusion beyond a well-established pre-hospital system.METHODS: This study sought to evaluate predictors of complete ST-segment resolution after percutaneous coronary intervention in ST-elevation myocardial infarction patients enrolled in the ATLANTIC trial. ST-segment analysis was performed on electrocardiograms recorded at the time of inclusion (pre-hospital electrocardiogram), and one hour after percutaneous coronary intervention (post-percutaneous coronary intervention electrocardiogram) by an independent core laboratory. Complete ST-segment resolution was defined as ≥70% ST-segment resolution.RESULTS: Complete ST-segment resolution occurred post-percutaneous coronary intervention in 54.9% ( n=800/1456) of patients and predicted lower 30-day composite major adverse cardiovascular and cerebrovascular events (odds ratio 0.35, 95% confidence interval 0.19-0.65; p<0.01), definite stent thrombosis (odds ratio 0.18, 95% confidence interval 0.02-0.88; p=0.03), and total mortality (odds ratio 0.43, 95% confidence interval 0.19-0.97; p=0.04). In multivariate analysis, independent negative predictors of complete ST-segment resolution were the time from symptoms to pre-hospital electrocardiogram (odds ratio 0.91, 95% confidence interval 0.85-0.98; p<0.01) and diabetes mellitus (odds ratio 0.6, 95% confidence interval 0.44-0.83; p<0.01); pre-hospital ticagrelor treatment showed a favorable trend for complete ST-segment resolution (odds ratio 1.22, 95% confidence interval 0.99-1.51; p=0.06).CONCLUSIONS: This study confirmed that post-percutaneous coronary intervention complete ST-segment resolution is a valid surrogate marker for cardiovascular clinical outcomes. In the current era of ST-elevation myocardial infarction reperfusion, patients' delay and diabetes mellitus are independent predictors of poor reperfusion and need specific attention in the future.

- AIMS: The aim of this study was to identify predictors of complete ST-segment resolution (STR) pre-primary percutaneous coronary intervention (PCI) in patients enrolled in the ATLANTIC trial.METHODS AND RESULTS: ECGs recorded at the time of inclusion (pre-hospital [pre-H]-ECG) and in the catheterisation laboratory before angiography (pre-PCI-ECG) were analysed by an independent core laboratory. Complete STR was defined as ≥70%. Complete STR occurred pre-PCI in 12.8% (204/1,598) of patients and predicted lower 30-day composite MACCE (OR=0.10, 95% CI: 0.002-0.57, p=0.001) and total mortality (OR=0.16, 95% CI: 0.004-0.95, p=0.035). Independent predictors of complete STR included the time from index event to pre-H-ECG (OR=0.94, 95% CI: 0.89-1.00, p=0.035), use of heparins before pre-PCI-ECG (OR=1.75, 95% CI: 1.25-2.45, p=0.001) and time from pre-H-ECG to pre-PCI-ECG (OR=1.09, 95% CI: 1.03-1.16, p=0.005). In the pre-H ticagrelor group, patients with complete STR had a significantly longer delay between pre-H-ECG and pre-PCI-ECG compared to patients without complete STR (median 53 [44-73] vs. 49 [38.5-61] mins, p=0.001); however, this was not observed in the control group (in-hospital ticagrelor) (50 [40-67] vs. 49 [39-61] mins, p=0.258).CONCLUSIONS: Short patient delay, early administration of anticoagulant and ticagrelor if a long transfer delay is expected may help to achieve reperfusion prior to PCI. Pre-H treatment may be beneficial in patients with longer transfer delays, allowing the drug to become biologically active.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE: We investigated, in the contemporary era of ST-elevation myocardial infarction (STEMI) treatment, the influence of diabetes mellitus (DM) on cardiovascular outcomes, and whether pre-hospital administration of ticagrelor may affect these outcomes in a subgroup of STEMI patients with DM.BACKGROUND: DM patients have high platelet reactivity and a prothrombotic condition which highlight the importance of an effective antithrombotic regimen in this high-risk population.METHODS: In toal 1,630 STEMI patients enrolled in the ATLANTIC trial who underwent primary percutaneous coronary intervention (PCI) were included. Multivariate analysis was used to explore the association of DM with outcomes and potential treatment-by-diabetes interaction was tested.RESULTS: A total of 214/1,630 (13.1%) patients had DM. DM was an independent predictor of poor myocardial reperfusion as reflected by less frequent ST-segment elevation resolution (≥70%) after PCI (OR 0.59, 95% CI 0.43-0.82, P < 0.01) and was an independent predictor of the composite 30-day outcomes of death/new myocardial infarction (MI)/urgent revascularization/definite stent thrombosis (ST) (OR 2.80, 95% CI 1.62-4.85, P < 0.01), new MI or definite acute ST (OR 2.46, 95% CI 1.08-5.61, P = 0.03), and definite ST (OR 10.00, 95% CI 3.54-28.22, P < 0.01). No significant interaction between pre-hospital ticagrelor vs in-hospital ticagrelor administration and DM was present for the clinical, electrocardiographic and angiographic outcomes as well as for thrombolysis in myocardial infarction major bleeding.CONCLUSIONS: DM remains independently associated with poor myocardial reperfusion and worse 30-day clinical outcomes. No significant interaction was found between pre-hospital vs in-hospital ticagrelor administration and DM status. Further approaches for the treatment of DM patients are needed.CLINICAL TRIAL REGISTRATION: clinicaltrials.gov identifier: NCT01347580.

Tidskriftsartikel (refereegranskat)abstract
- The aim of this follow-up study has been to assess retinopathy and change of treatment to insulin therapy as risk factors for mortality in diabetic patients participating in a control and screening programme for retinopathy. A total of 3220 diabetic patients, 483 with an age at diagnosis <30 years, and 2737 with an age at diagnosis ≤30 years, were included. Retinopathy was graded on fundus photographs using the Wisconsin Scale, and the visual acuity was assessed. The average HbA(1c) value was calculated for each patient for the previous 8 years to estimate long-term glycaemic control. Mortality data were obtained from death certificates. Two hundred and sixty-three diabetic patients (8.2 %) died during the mean follow-up time of 3.4 years, 13 (2.7 %) of those with younger-onset (<30 years) and 250 (9.1%) of those with older-onset (≤30 years) diabetes. Of them, 148 (56.3 %) died from cardiovascular and 23 (8.7 %) from cerebrovascular disorders. After adjusting for differences in age and sex, more severe retinopathy and the use of antihypertensive drugs were associated with a decreased overall survival rate as well as an increased mortality from cardiovascular and cerebrovascular diseases. A statistically significant association between HbA(tc) values in the highest quartile, i.e. ≤8.4 %, and cardiovascular and all cause mortality did not remain when retinopathy was entered into the multivariate analyses. Duration of diabetes, but not change of treatment to insulin therapy, was associated with higher cardiovascular mortality in patients whose diabetes was diagnosed after the age of 30 years. We conclude that severe retinopathy, use of antihypertensive drugs, and poor glycaemic control predicted death from cardiovascular disease in diabetic patients participating in an ophthalmological screening programme.

- Objective: To evaluate meat intake patterns in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohorts. Design and setting: 24-Hour dietary recalls were assessed within the framework of a prospective cohort study in 27 centres across 10 European countries by means of standardised computer-assisted interviews. Subjects: In total, 22 924 women and 13 031 men aged 35-74 years. Results: Mean total meat intake was lowest in the 'health-conscious' cohort in the UK (15 and 21 g day(-1) in women and men, respectively) and highest in the north of Spain, especially in San Sebastian (124 and 234 g day(-1), respectively). In the southern Spanish centres and in Naples (Italy), meat consumption was distinctly lower than in the north of these countries. Central and northern European centres/countries showed rather similar meat consumption patterns, except for the British and French cohorts. Differences in the intake of meat sub-groups (e.g. red meat, processed meat) across EPIC were even higher than found for total meat intake. With a few exceptions, the Mediterranean EPIC centres revealed a higher proportion of beef/veal and poultry and less pork or processed meat than observed in central or northern European centres. The highest sausage consumption was observed for the German EPIC participants, followed by the Norwegians, Swedish, Danish and Dutch. Conclusions: The results demonstrate distinct differences in meat consumption patterns between EPIC centres across Europe. This is an important prerequisite for obtaining further insight into the relationship between meat intake and the development of chronic diseases.

- In order to investigate potential selection bias in population-based cohort studies, participants (n = 28098) and non-participants (n = 40807) in the Malmo Diet and Cancer Study (MDCS) were compared with regard to cancer incidence and mortality. MDCS participants were also compared with participants in a mailed health survey with regard to subjective health, socio-demographic characteristics and lifestyle. Cancer incidence prior to recruitment was lower in non-participants, Cox proportional hazards analysis yielded a relative risk (RR) with a 95% confidence interval of 0.95 (0.90-1.00), compared with participants. During recruitment, cancer incidence was higher in non-participants, RR: 1.08 (1.01-1.17). Mortality was higher in non-participants both during, 3.55 (3.13-4.03), and following the recruitment period, 2.21 (2.03-2.41). The proportion reporting good health was higher in the MDCS than in the mailed health survey (where 74.6% participated), but the socio-demographic structure was similar. We conclude that mortality is higher in non-participants than in participants during recruitment and follow-up. It is also suggested that non-participants may have a lower cancer incidence prior to recruitment but a higher incidence during the recruitment period.

- OBJECTIVES The aim of this landmark exploratory analysis, ATLANTIC-H-24, was to evaluate the effects of pre-hospital ticagrelor during the first 24 h after primary percutaneous coronary intervention (PCI) in the ATLANTIC (Administration of Ticagrelor in the cath Lab or in the Ambulance for New ST elevation myocardial infarction to open the Coronary artery) study. BACKGROUND The ATLANTIC trial in patients with ongoing ST-segment elevation myocardial infarction showed that pre-hospital ticagrelor was safe but did not improve pre-PCI coronary reperfusion compared with in-hospital ticagrelor. We hypothesized that the effect of pre-hospital ticagrelor may not have manifested until after PCI due to the rapid transfer time (31 min). METHODS The ATLANTIC-H-24 analysis included 1,629 patients who underwent PCI, evaluating platelet reactivity, Thrombolysis In Myocardial Infarction flow grade 3, >= 70% ST-segment elevation resolution, and clinical endpoints over the first 24 h. RESULTS Following PCI, largest between-group differences in platelet reactivity occurred at 1 to 6 h; coronary reperfusion rates numerically favored pre-hospital ticagrelor, and the degree of ST-segment elevation resolution was significantly greater in the pre-hospital group (median, 75.0% vs. 71.4%; p = 0.049). At 24 h, the composite ischemic endpoint was lower with pre-hospital ticagrelor (10.4% vs. 13.7%; p = 0.039), as were individual endpoints of definite stent thrombosis (p = 0.0078) and myocardial infarction (p = 0.031). All endpoints except death (1.1% vs. 0.2%; p = 0.048) favored pre-hospital ticagrelor, with no differences in bleeding events. CONCLUSIONS The effects of pre-hospital ticagrelor became apparent after PCI, with numerical differences in platelet reactivity and immediate post-PCI reperfusion, associated with reductions in ischemic endpoints, over the first 24 h, whereas there was a small excess of mortality.

- Background In order to better understand the role of work environment in the earlier stages of the cardiovascular disease process, we wanted to investigate the influence of work-related psychosocial factors on preclinical atherosclerosis. Methods Cross-sectional data was used to examine the association between psychological job demands, job decision latitude, and carotid atherosclerosis in 2658 vocationally-active Swedish men and women, ages 46–65, from the general population. Odds ratios of carotid plaque prevalence and carotid artery intima-media thickness (IMT), determined by B-mode ultrasound, were estimated across combinations of job demands and decision latitude. Results Women in job situations with high demands and low decision latitude (‘job strain’) showed a high plaque prevalence odds (odds ratio [OR] = 1.68, 95% CI: 1.14, 2.48), and a thicker IMT in the carotid bifurcation area (mean difference: 0.15 mm, 95% CI: 0.07, 0.23) compared with women in job situations with low demands and high decision latitude (‘relaxed’). Adjustment for covariates only slightly reduced the magnitude of these associations. No such associations were seen in men. However, women in job situations with high demands and high decision latitude (‘active’) also showed high odds for carotid plaque, and a thicker IMT in the carotid bifurcation, compared with women in ‘relaxed’ job situations. In men, those in ‘active’ job situations had a low carotid plaque prevalence odds, while IMT in the carotid bifurcation did not differ from those in ‘relaxed’ job situations. Results showed only weak associations with IMT in the common carotid artery (CCA) in both men and women. Conclusion The specific hypothesis that high job demands interact synergistically with low decision latitude in the development of carotid atherosclerosis could not be supported in this study, neither in men nor in women. Instead a more complex pattern of interaction between job demands and decision latitude was shown.

- Background Differences in comorbidity, pharmacotherapy, cardiovascular (CV) outcome, and mortality between myocardial infarction (MI) patients and peripheral arterial disease (PAD) patients are not well documented. Aim The aim of this study was to compare comorbidity, treatment patterns, CV outcome, and mortality in MI and PAD patients, focusing on sex differences. Methods This observational, population-based study used data retrieved from mandatory Swedish national registries. The risks of MI and death were assessed by Kaplan-Meier analysis. Secondary preventive drug use was characterized. Cox proportional risk hazard modelling was used to determine the risk of specific events. Results Overall, 91,808 incident MI patients and 52,408 PAD patients were included. CV mortality for MI patients at 12, 24, and 36 months after index was 12.3%, 19.3%, and 25.4%, and for PAD patients it was 15.5%, 23.4%, and 31.0%. At index, 89% of MI patients and 65% of PAD patients used aspirin and 74% and 53%, respectively, used statins. Unlike MI women, women with PAD had a lower rate of other CV-related comorbidities and a lower risk of CV events (age-adjusted hazard ratio 0.81, 95% confidence interval 0.79-0.84), CV death (0.78, 0.75-0.82), and all-cause death (0.78, 0.76-0.80) than their PAD male counterparts. Conclusion PAD patients were less intensively treated and had a higher CV mortality than MI patients. Women with PAD were less likely than men to present with established polyvascular disease, whereas the opposite was true of women with MI. This result indicates that the lower-limb vasculature may more often be the index site for atherosclerosis in women.

- Background Glycoprotein IIb/IIIa inhibitors (GPIs) in combination with clopidogrel improve clinical outcome in ST-elevation myocardial infarction (STEMI); however, finding a balance that minimizes both thrombotic and bleeding risk remains fundamental. The efficacy and safety of GPI in addition to ticagrelor, a more potent P2Y12-inhibitor, have not been fully investigated. Methods 1,630 STEMI patients who underwent primary percutaneous coronary intervention (PCI) were analyzed in this subanalysis of the ATLANTIC trial. Patients were divided in three groups: no GPI, GPI administration routinely before primary PCI, and GPI administration in bailout situations. The primary efficacy outcome was a composite of death, myocardial infarction, urgent target revascularization, and definite stent thrombosis at 30 days. The safety outcome was non-coronary artery bypass graft (CABG)-related PLATO major bleeding at 30 days. Results Compared with no GPI ( n = 930), routine GPI ( n = 525) or bailout GPI ( n = 175) was not associated with an improved primary efficacy outcome (4.2% no GPI vs. 4.0% routine GPI vs. 6.9% bailout GPI; p = 0.58). After multivariate analysis, the use of GPI in bailout situations was associated with a higher incidence of non-CABG-related bleeding compared with no GPI (odds ratio [OR] 2.96, 95% confidence interval [CI] 1.32-6.64; p = 0.03). However, routine GPI use compared with no GPI was not associated with a significant increase in bleeding (OR 1.78, 95% CI 0.88-3.61; p = 0.92). Conclusion Use of GPIs in addition to ticagrelor in STEMI patients was not associated with an improvement in 30-day ischemic outcome. A significant increase in 30-day non-CABG-related PLATO major bleeding was seen in patients who received GPIs in a bailout situation.
