Introduction: A diet rich in marine n-3 polyunsaturated fatty acids (PUFAs) may lower the risk of coronary heart disease and ischemic stroke. However, the association between intake of marine n-3 PUFAs and risk of hemorrhagic stroke has only been sparsely explored. We aimed to investigate the associations between intake of the major marine n-3 PUFAs, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) and their sum, in relation to incident hemorrhagic stroke and its subtypes, intracerebral hemorrhage (ICH) and subarachnoid hemorrhage (SAH). Methods: We analyzed data from the Danish Diet, Cancer and Health Cohort, which was established between 1993 and 1997. Information on dietary intake of marine n-3 PUFAs was obtained through a validated food frequency questionnaire. Potential hemorrhagic stroke cases were identified by linkage to the Danish National Patient Register and subsequently validated. Hazard ratios obtained by Cox proportional hazard regression analyses were used as measures of association. Results: A total of 394 subjects among 55,519 individuals developed hemorrhagic stroke during a median follow-up period of 13.5 years. In multivariable analyses including adjustment for established risk factors, we observed weak and statistically nonsignificant inverse associations between intake of EPA, DHA, and EPA + DHA and the rate of incident hemorrhagic stroke. In analyses of hemorrhagic stroke subtypes, we found indications of lower rates of ICH among participants in the highest quartile of EPA, DHA, and EPA + DHA compared with those in the lowest quartile and indications of lower rates of SAH in the highest quartile of EPA intake compared to the lowest quartile, but the findings were statistically nonsignificant. Conclusions: Inversely statistically nonsignificant associations were found between EPA, DHA, and EPA + DHA and hemorrhagic stroke. [ABSTRACT FROM AUTHOR]

Background A high intake of marine n-3 polyunsaturated fatty acids (PUFAs) may lower the risk of coronary heart disease and ischemic stroke. The association between intake of marine n-3 PUFAs and development of peripheral artery disease (PAD), however, remains unexplored. We hypothesised that intake of marine n-3 PUFAs, eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA) and the sum of EPA + DHA was associated with a lower risk of incident PAD. Methods We used data from the Danish Diet, Cancer and Health cohort and investigated the associations between intake of EPA, DHA and EPA + DHA and development of PAD. Information on intake of n-3 PUFAs was obtained through a validated food frequency questionnaire. Potential PAD cases were identified through linkage to the Danish National Patient Register and subsequently, all cases were validated. Results Data were available from 55,248 participants and during a median of 13.6 years of follow-up, 950 cases of PAD were identified. Multivariate Cox regression analyses with adjustments for established risk factors showed no statistically significant associations between intake of EPA (p = 0.255), DHA (p = 0.071) or EPA + DHA (p = 0.168) and the rate of incident PAD. Conclusions We did not confirm our hypothesis that intake of EPA, DHA or EPA + DHA was associated with a lower risk of incident PAD., Author(s): Linda Tram [sup.1] , Christian S.

The field of personalized medicine (PM) has grown rapidly because of the "omics revolution", but PM may be difficult for patients to comprehend. This study sought to explore head and neck cancer (HNC) patients' positions and knowledge of PM, gene tests, and follow-up and to compare HNC patients' positions to a sample from a national Danish questionnaire. To do this, patients with prior HNC were invited to participate in a questionnaire. Initial interviews revealed a heterogenic understanding of PM between patients. A total of 226 patients were included in the survey and 177 patients with complete data were included for analysis. Most patients were more positive than negative towards gene tests and gene research (83% and 93%, respectively), but 72% had little or no knowledge of the subject. Almost all patients, 98%, were satisfied with their follow-up. Significantly more patients with HNC were positive towards gene research compared to a sample from a national Danish questionnaire (p < 0.001). Patients with HNC were positive towards gene tests and PM, but patients may not understand or comprehend the information given, and it is important to inform and educate patients and health professionals to establish common ground in PM.

During the last two decades, several cases of venous thrombosis (VTE) after a prolonged period at a computer have been described, denominated as "eThrombosis". Video gaming on a computer has become very popular and can be a social activity where several players gather to play against each other or in a virtual environment for several days ("LAN (i.e., Local Area Network) parties") where the participants are sedentary and consuming calorie-rich food items. The aim of this study was to investigate potential coagulation activation during a 42 h LAN party. Nine male gamers volunteered for the LAN party. Citrated blood was sampled before and every 6 h, and plasma was analyzed for thrombin generation, thrombin–antithrombin complexes (TAT), prothrombin fragment 1 + 2 (F1 + 2), and D-dimer. Thrombin generation increased slightly but not significantly during the LAN party, whereas the coagulation activation markers were unchanged. These results do not indicate that the coagulation system is activated significantly during 42 h of gaming with minimal physical activity. Although increased activity cannot be excluded, it does not directly indicate a risk of VTE in general. [ABSTRACT FROM AUTHOR]

Acute intestinal necrosis (AIN) is a disease with devastating high mortality. AIN due to obstructed arterial blood flow has a blurred clinical presentation. Timely diagnosis is paramount, and a blood-based biomarker is warranted to increase patient survival. We aimed to assess intestinal fatty acid binding protein (I-FABP) and endothelin-1 as diagnostic biomarkers for AIN. To our knowledge, this is the first study exploring endothelin-1 in AIN patients from a general surgical population. We conducted a single-centre nested case–control study comparing acutely admitted AIN patients to age- and sex-matched non-AIN patients during 2015–2016. I-FABP and endothelin-1 were analysed using an enzyme-linked immunosorbent assay. L-lactate levels were also measured in all patients. Cut-offs were estimated using receiver operator characteristic curves, and the diagnostic performance was estimated using the area under the receiver operator characteristic curve (AUC). We identified 43 AIN patients and included 225 matched control patients. Median levels of I-FABP, endothelin-1 and L-lactate were 3550 (IQR: 1746–9235) pg/ml, 3.91 (IQR: 3.33–5.19) pg/ml and 0.92 (IQR: 0.74–1.45) mM in AIN patients and 1731 (IQR: 1124–2848) pg/ml, 2.94 (IQR: 2.32–3.82) pg/ml and 0.85 (IQR: 0.64-1.21) mM in control patients, respectively. The diagnostic performances of endothelin-1 and of I-FABP + endothelin-1 combined were moderate. Endothelin-1 alone revealed an AUC of 0.74 (0.67; 0.82). The sensitivity and specificity of endothelin-1 were 0.81 and 0.64, respectively. I-FABP and endothelin-1 are promising biomarkers for AIN, with moderate diagnostic performance compared with the commonly used biomarker L-lactate. ClinicalTrials.gov: NCT05665946.
