Background: Thrombolysis should be administered as soon as possible to suitable patients with acute ischaemic stroke. We introduced a new protocol for patients who had a stroke to achieve reduced door-to-needle times for the best possible outcome. Since then, we have closely monitored each patient who had a stroke. Our goal was to assess whether statistical process control charts could be useful in detecting deviations in door-to-needle times when using four well-known rules applied by Western Electric (WE rules 1-4)., Methods: We analysed retrospectively door-to-needle times of together 200 acute ischaemic stroke patients before and after the implementation of our new stroke protocol. In addition, 25 patients at the time of reorganisation (transition period) were analysed. Statistical process control chart rules WE 1-WE 4 were applied to detect door-to-needle deviations and to monitor process uniformity., Results: Before the implementation of the protocol, median door-to-needle time was 53 min and after the implementation 20 min. Statistical process control chart rules were triggered only once in 100 patients before the reorganisation but seven times in 25 patients during the transition period. None of the rules WE 1-4 were activated after the reorganisation, indicating the stability of the reorganised acute ischaemic stroke process., Conclusions: The use of statistical process control charts demonstrated a significant reduction in door-to-needle times during the reorganisation. Further, it showed that the acute ischaemic stroke process with a 20 min door-to-needle time is very stable., Competing Interests: No, there are no competing interests., (Copyright © Author(s) (or their employer(s)) 2024.

Aim: Blood Sampling Guidelines have been developed to target European emergency medicine-related professionals involved in the blood sampling process (e.g. physicians, nurses, phlebotomists working in the ED), as well as laboratory physicians and other related professionals. The guidelines population focus on adult patients. The development of these blood sampling guidelines for the ED setting is based on the collaboration of three European scientific societies that have a role to play in the preanalytical phase process: EuSEN, EFLM, and EUSEM. The elaboration of the questions was done using the PICO procedure, literature search and appraisal was based on the GRADE methodology. The final recommendations were reviewed by an international multidisciplinary external review group., Results: The document includes the elaborated recommendations for the selected sixteen questions. Three in pre-sampling, eight regarding sampling, three post-sampling, and two focus on quality assurance. In general, the quality of the evidence is very low, and the strength of the recommendation in all the questions has been rated as weak. The working group in four questions elaborate the recommendations, based mainly on group experience, rating as good practice., Conclusions: The multidisciplinary working group was considered one of the major contributors to this guideline. The lack of quality information highlights the need for research in this area of the patient care process. The peculiarities of the emergency medical areas need specific considerations to minimise the possibility of errors in the preanalytical phase., (© 2024 Walter de Gruyter GmbH, Berlin/Boston.)

Background: All-cause mortality and cardiovascular disease are increased in subjects with metabolic syndrome (MetS). Risk scores are used to predict individual risk of heart disease. We performed a long-term follow-up study to investigate whether risk scores and cardiovascular risk factors such as arterial stiffness, high-sensitive C-reactive protein (hs-CRP) and oxidized LDL (OxLDL) can be used to predict cardiovascular events in Finnish men with MetS., Methods: After baseline measurements we followed 105 Finnish men aged 30 to 65 years with MetS for a mean period of 16.4 years. The primary outcome of the study was a composite of myocardial infarction, stroke, symptomatic vascular disease diagnosed with invasive angiography, coronary or peripheral revascularization, amputation due to peripheral vascular disease, cardiovascular death and non-cardiovascular death. The endpoints were retrieved from electronic medical records., Results: The number of acute myocardial infarctions and strokes during the first 10 years was lower than estimated by FINRISK score but SCORE predicted cardiovascular death correctly. During the whole follow-up period, 27 of 105 participants (25.8%) had 30 endpoint events. The incidence of the primary composite outcome was significantly lower in subjects with hs-CRP < 1.0 mg/L than in subjects with hs-CRP ≥ 1.0 mg/L (6 of 41 subjects [14.6%] vs. 21 of 64 subjects [32.8%]; p = 0.036). The incidence of the primary composite outcome was higher among subjects with large artery elasticity classified as borderline compared to subjects with normal large artery elasticity (5 of 10 subjects [50%] vs. 22 of 93 subjects [24%]; p = 0.05). There was no difference in the incidence of primary composite outcome in groups with different degrees of small artery elasticity or different level of oxLDL., Conclusions: Men with MetS who had hs-CRP ≥ 1.0 mg/L had higher risk for CVD and all-cause mortality than those with hs-CRP of < 1.0 mg/L. This also applies to subjects with borderline decreased large artery elasticity. The amount of OxLDL had no predictive value on the incidence of CVD and all-cause mortality. Men with MetS participating in the Hämeenlinna Metabolic Syndrome Research Program without lifestyle or drug intervention had better outcome for myocardial infarction or stroke than estimated by the FINRISK score., Trial Registration: ClinicalTrials.gov NCT01119404 retrospectively registered 07/05/2010., (© 2024.

When studying emergency department (ED) visits, electronic health record systems of hospitals provide a good basis for retrospective studies. However, many intoxication patients presenting to the ED, may not be identified retrospectively if only a single search method is applied. In this study, a new four-way combined patient search method was used to retrospectively identify intoxication patients presenting to the ED. The search included reason for admission to the ED, laboratory results related to intoxication diagnostics, ICD-10 codes, and a novel free word search (FWS) of patient records. After the automated search, the researcher read the medical records of potential substance abuse patients to form comprehensive profiles and remove irrelevant cases. The addition of a free word search identified 36% more substance abuse patients than the combination of the other three methods mentioned above. Patients identified by the FWS search alone were generally admitted to the ED for trauma or mental health problems and were often found to be heavily under the influence of alcohol and/or drugs. The main intoxicants were ethanol and benzodiazepines. The free word search was highly complementary to traditional patient search methods, highlighting the importance of the combined patient search method in retrospective data collection., (© 2024.

The current evidence suggests that higher levels of crowding in the Emergency Department (ED) have a negative impact on patient outcomes, including mortality. However, only limited data are available about the association between crowding and mortality, especially for patients discharged from the ED. The primary objective of this study was to establish the association between ED crowding and overall 10-day mortality for non-critical patients. The secondary objective was to perform a subgroup analysis of mortality risk separately for both admitted and discharged patients. An observational single-centre retrospective study was conducted in the Tampere University Hospital ED from January 2018 to February 2020. The ED Occupancy Ratio (EDOR) was used to describe the level of crowding and it was calculated both at patient's arrival and at the maximum point during the stay in the ED. Age, gender, Emergency Medical Service transport, triage acuity, and shift were considered as confounding factors in the analyses. A total of 103,196 ED visits were included. The overall 10-day mortality rate was 1.0% (n = 1022). After controlling for confounding factors, the highest quartile of crowding was identified as an independent risk factor for 10-day mortality. The results were essentially similar whether using the EDOR at arrival (OR 1.31, 95% CI 1.07-1.61, p = 0.009) or the maximum EDOR (OR 1.27, 95% CI 1.04-1.56, p = 0.020). A more precise, mortality-associated threshold of crowding was identified at EDOR 0.9. The subgroup analysis did not yield any statistically significant findings. The risk for 10-day mortality increased among non-critical ED patients treated during the highest EDOR quartile., (© 2023. The Author(s).)

Background: Emergency Medicine (EM) is an independent specialty in all five Nordic countries. This study aims to evaluate the structure of post-graduate EM training in the area., Methods: A leading hospital or hospitals in EM training in each country were identified. An e-survey was sent to each hospital to gather data on patient volume and physician staffing, curriculum, trainee supervision, and monitoring of progression in training., Results: Data were collected from one center in Iceland and Norway, two in Finland and Sweden, and four centers in Denmark. The data from each country in Denmark, Finland, and Sweden, were pooled to represent that country. The percentage of consultants with EM specialist recognition ranged from 49-100% of all consultants working in the participating departments. The number of patients seen annually per each full time EM consultant was almost three times higher in Finland than in Sweden. In Iceland, Denmark, and Sweden a consultant was present 24/7 in the ED but not in all centers in the other countries. The level of trainee autonomy in clinical practice varied between countries. Requirements for completing standardized courses, completing final exams, scientific and quality improvement projects, and evaluation of trainee progression, varied between the countries., Conclusions: All Nordic countries have established EM training programs. Despite cultural similarities, there are significant differences in how the EM training is structured between the countries. Writing and implementing a standardized training curriculum and assessment system for EM training in the Nordic countries should be considered., (© 2023. The Author(s).)

Emergency department (ED) crowding is a well-recognized threat to patient safety and it has been repeatedly associated with increased mortality. Accurate forecasts of future service demand could lead to better resource management and has the potential to improve treatment outcomes. This logic has motivated an increasing number of research articles but there has been little to no effort to move these findings from theory to practice. In this article, we present first results of a prospective crowding early warning software, that was integrated to hospital databases to create real-time predictions every hour over the course of 5 months in a Nordic combined ED using Holt-Winters' seasonal methods. We show that the software could predict next hour crowding with an AUC of 0.94 (95% CI: 0.91-0.97) and 24 hour crowding with an AUC of 0.79 (95% CI: 0.74-0.84) using simple statistical models. Moreover, we suggest that afternoon crowding can be predicted at 1 p.m. with an AUC of 0.84 (95% CI: 0.74-0.91)., (© 2023. The Author(s).)

Background: The use of point-of-care ultrasound (POCUS) is increasing. Numerous investigators have evaluated the learning curves in POCUS, but there are no published studies on how emergency physicians perceive their own competence level with this skill., Methods: A nationwide survey amongst Finnish emergency physicians was conducted. The respondents reported their use of POCUS and how it has affected their clinical decision-making. The number of POCUS examinations performed was compared to the self-assessed skill level with different applications. Cut-off values were determined for the number of examinations required to acquire a good self-assessed skill level in each POCUS application. The correlation between self-confidence and the self-estimated skill level was analyzed. Several different statistical methods were used, such as Student's t-test, Pearson's correlation test, Loess method and ROC curve analysis., Results: A total of 134 out of 253 Finnish emergency medicine specialists and residents (52%) responded to the survey. The most commonly used POCUS applications were POCUS-assisted procedures, pleural effusion and pneumothorax, inferior vena cava and lower extremity deep venous thrombosis. The initial rate of perceived skill acquisition was very steep with the curve flattening with greater skill and more experience. The number of examinations performed to reach a self-assessed good competence varied from seven to 75 with different applications. The lowest cut-off point for self-assessed good competence was obtained for rapid ultrasound for the shock and hypotension-protocol and the highest for focused cardiac examinations. There was an excellent correlation between self-confidence and the self-assessed skill level., Conclusions: The Finnish emergency practitioners' self-assessed development of POCUS skills parallels the previously published learning curves of POCUS. The correlation of self-confidence and the self-assessed skill level was found to be excellent. These findings add information on the development of perceived POCUS skills amongst emergency physicians and could complement a formal performance assessment., (© 2023. The Author(s).)

Background: Our aim is to describe and compare the profile and outcome of patients attending the ED with a confirmed COVID-19 infection with patients with a suspected COVID-19 infection. Methods: We conducted a multicentric retrospective study including adults who were seen in 21 European emergency departments (ED) with suspected COVID-19 between 9 March and 8 April 2020. Patients with either a clinical suspicion of COVID-19 or confirmed COVID-19, detected using either a RT-PCR or a chest CT scan, formed the C+ group. Patients with non-confirmed COVID-19 (C− group) were defined as patients with a clinical presentation in the ED suggestive of COVID-19, but if tests were performed, they showed a negative RT-PCR and/or a negative chest CT scan. Results: A total of 7432 patients were included in the analysis: 1764 (23.7%) in the C+ group and 5668 (76.3%) in the C− group. The population was older (63.8 y.o. ±17.5 vs. 51.8 y.o. +/− 21.1, p < 0.01), with more males (54.6% vs. 46.1%, p < 0.01) in the C+ group. Patients in the C+ group had more chronic diseases. Half of the patients (n = 998, 56.6%) in the C+ group needed oxygen, compared to only 15% in the C− group (n = 877). Two-thirds of patients from the C+ group were hospitalized in ward (n = 1128, 63.9%), whereas two-thirds of patients in the C− group were discharged after their ED visit (n = 3883, 68.5%). Conclusion: Our study was the first in Europe to examine the emergency department’s perspective on the management of patients with a suspected COVID-19 infection. We showed an overall more critical clinical situation group of patients with a confirmed COVID-19 infection.

Background and Objective: Emergency Department (ED) overcrowding is a chronic international issue that is associated with adverse treatment outcomes. Accurate forecasts of future service demand would enable intelligent resource allocation that could alleviate the problem. There has been continued academic interest in ED forecasting but the number of used explanatory variables has been low, limited mainly to calendar and weather variables. In this study we investigate whether predictive accuracy of next day arrivals could be enhanced using high number of potentially relevant explanatory variables and document two feature selection processes that aim to identify which subset of variables is associated with number of next day arrivals. Performance of such predictions over longer horizons is also shown., Methods: We extracted numbers of total daily arrivals from Tampere University Hospital ED between the time period of June 1, 2015 and June 19, 2019. 158 potential explanatory variables were collected from multiple data sources consisting not only of weather and calendar variables but also an extensive list of local public events, numbers of website visits to two hospital domains, numbers of available hospital beds in 33 local hospitals or health centres and Google trends searches for the ED. We used two feature selection processes: Simulated Annealing (SA) and Floating Search (FS) with Recursive Least Squares (RLS) and Least Mean Squares (LMS). Performance of these approaches was compared against autoregressive integrated moving average (ARIMA), regression with ARIMA errors (ARIMAX) and Random Forest (RF). Mean Absolute Percentage Error (MAPE) was used as the main error metric., Results: Calendar variables, load of secondary care facilities and local public events were dominant in the identified predictive features. RLS-SA and RLS-FA provided slightly better accuracy compared ARIMA. ARIMAX was the most accurate model but the difference between RLS-SA and RLS-FA was not statistically significant., Conclusions: Our study provides new insight into potential underlying factors associated with number of next day presentations. It also suggests that predictive accuracy of next day arrivals can be increased using high-dimensional feature selection approach when compared to both univariate and nonfiltered high-dimensional approach. Performance over multiple horizons was similar with a gradual decline for longer horizons. However, outperforming ARIMAX remains a challenge when working with daily data. Future work should focus on enhancing the feature selection mechanism, investigating its applicability to other domains and in identifying other potentially relevant explanatory variables., (© 2022.

Background: Acute heart failure patients are often encountered in emergency departments (ED) from 11% to 57% using emergency medical services (EMS). Our aim was to evaluate the association of EMS use with acute heart failure patients' ED management and short-term outcomes., Methods: This was a sub-analysis of a European EURODEM study. Data on patients presenting with dyspnoea were collected prospectively from European EDs. Patients with ED diagnosis of acute heart failure were categorized into two groups: those using EMS and those self-presenting (non- EMS). The independent association between EMS use and 30-day mortality was evaluated with logistic regression., Results: Of the 500 acute heart failure patients, with information about the arrival mode to the ED, 309 (61.8%) arrived by EMS. These patients were older (median age 80 vs. 75 years, p < 0.001), more often female (56.4% vs. 42.1%, p = 0.002) and had more dementia (18.7% vs. 7.2%, p < 0.001). On admission, EMS patients had more often confusion (14.2% vs. 2.1%, p < 0.001) and higher respiratory rate (24/min vs. 21/min, p = 0.014; respiratory rate > 30/min in 17.1% patients vs. 7.5%, p = 0.005). The only difference in ED management appeared in the use of ventilatory support: 78.3% of EMS patients vs. 67.5% of non- EMS patients received supplementary oxygen (p = 0.007), and non-invasive ventilation was administered to 12.5% of EMS patients vs. 4.2% non- EMS patients (p = 0.002). EMS patients were more often hospitalized (82.4% vs. 65.9%, p < 0.001), had higher in-hospital mortality (8.7% vs. 3.1%, p = 0.014) and 30-day mortality (14.3% vs. 4.9%, p < 0.001). The use of EMS was an independent predictor of 30-day mortality (OR = 2.54, 95% CI 1.11-5.81, p = 0.027)., Conclusion: Most acute heart failure patients arrive at ED by EMS. These patients suffer from more severe respiratory distress and receive more often ventilatory support. EMS use is an independent predictor of 30-day mortality., (© 2022. The Author(s).)

Introduction: Gorham's disease is a very rare musculoskeletal disorder characterized by progressive resorption of one or more skeletal bones. Most of the 200 cases reported earlier are diagnosed before the age of 40 years. Due to rarity, the diagnosis of Gorham's disease in the Emergency Department may be very difficult., Case Presentation: We report a case of Gorham's disease. A 23-year old Caucasian man presented to the Emergency Department with a significant loss of power and sensation of the lower limbs and lower torso. Clinical examination, computed tomography, and magnetic resonance imaging revealed resorption of the ribs and vertebrae, severe kyphosis, and spinal stenosis in the thoracic area. The patient underwent several surgical procedures, including spondylodesis and decompression, and made a good initial recovery. Biopsy confirmed the diagnosis of Gorham's disease., Conclusion: We present a young man with Gorham's disease visiting the Emergency Department. After the proper diagnosis and treatment, our patient had good outcome, although the etiology of this rare disease is uncertain., (© 2021. The Author(s).)

The use of biliary stents has become a common and usually safe procedure. However, the migration of biliary stents is an uncommon but well-recognized event after endoscopic retrograde cholangiopancreatography. The migration of plastic stents usually does not result in complications and are spontaneously eliminated from the gastro-intestinal tract. Additionally, <1% of migrated stents result in intestinal perforation, which typically occurs at the duodenum. Chemotherapeutic agents may cause gastrointestinal toxicity and hematologic toxicity predisposing to neutropenic enterocolitis. The current study reports a patient with an unprecedented case of biliary stent migration resulting in appendiceal gangrene and perforation in a neutropenic patient under chemotherapy for metastatic small cell lung cancer., Competing Interests: The authors declare that they have no competing interests., (Copyright © 2020, Spandidos Publications.)

Background: Emergency departments (EDs) worldwide have been in the epicentre of the novel coronavirus disease (COVID-19). However, the impact of the pandemic and national emergency measures on the number of non-COVID-19 presentations and the assessed acuity of those presentations remain uncertain., Methods: We acquired a retrospective cohort containing all ED visits in a Finnish secondary care hospital during years 2018, 2019 and 2020. We compared the number of presentations in 2020 during the national state of emergency, i.e. from March 16 to June 11, with numbers from 2018 and 2019. Presentations were stratified using localized New York University Emergency Department Algorithm (NYU-EDA) to evaluate changes in presentations with different acuity levels., Results: A total of 27,526 presentations were observed. Compared to previous two years, total daily presentations were reduced by 23% (from 113 to 87, p < .001). In NYU-EDA classes, Non-Emergent visits were reduced the most by 42% (from 18 to 10, p < .001). Emergent presentations were reduced by 19 to 28% depending on the subgroup (p < .001). Number of injuries were reduced by 25% (from 27 to 20, p < .001). The NYU-EDA distribution changed statistically significantly with 4% point reduction in Non-Emergent visits (from 16 to 12%, p < .001) and 0.9% point increase in Alcohol-related visits (from 1.6 to 2.5%, p < .001)., Conclusions: We observed a significant reduction in total ED visits in the course of national state of emergency. Presentations were reduced in most of the NYU-EDA groups irrespective of the assessed acuity. A compensatory increase in presentations was not observed in the course of the 3 month lockdown. This implies either reduction in overall morbidity caused by decreased societal activity or widespread unwillingness to seek required medical advice.

Background: Acute appendicitis is a global disease and a very common indication for emergency surgery worldwide. The need for hospital resources is therefore constantly high. The administration in Kanta-Häme Central Hospital, Southern Finland, called for an urgent reorganisation due to shortage of hospital beds at the department of general surgery. Postoperative treatment pathway of patients with nonperforated acute appendicitis was ordered to take place in the Emergency Department (ED). The aim of this study was to assess, whether this reorganisation was feasible and safe, i.e. did it affect the length of in-hospital stay (LOS) and the 30-day complication rate., Methods: This is a retrospective pre- and post-intervention analysis. After the reorganisation, most patients with nonperforated appendicitis were followed postoperatively at the 24-h observation unit of the ED instead of surgical ward. Patients operated during the first 3 months after the reorganisation were compared to those operated during the 3 months before it. A case met inclusion criteria if there were no signs of appendiceal perforation during surgery. Exclusion criteria comprised age < 18 years and perforated disease., Results: Appendicectomy was performed on 112 patients, of whom 62 were adults with nonperforated appendicitis. Twenty-seven of the included patients were treated before the reorganisation, and 35 after it. Twenty of the latter were followed only at the ED. Postoperative LOS decreased significantly after the reorganisation. Median postoperative time till discharge was 15.7 h for all patients after the reorganisation compared to 24.4 h before the reorganisation (standard error 6.2 h, 95% confidence interval 2.3-15.2 h, p < 0.01). There were no more complications in the group treated postoperatively in the ED., Conclusions: Early discharge of patients with nonperforated appendicitis after enforced urgent reorganisation of the treatment pathway in the ED observation unit is safe and feasible. Shifting the postoperative monitoring and the discharge policy of such patients to the ED - instead of the surgical ward - occurred in the majority of the cases after the reorganisation. This change may spare resources as in our series it resulted in a significantly shorter LOS without any increase in the 30-day complication rate.

Study Objective: Thrombolysis with tissue plasminogen activator should occur promptly after ischemic stroke onset. Various strategies have attempted to improve door-to-needle time. Our objective is to evaluate a strategy that uses an emergency physician-based protocol when no stroke neurologist is available., Methods: This was a retrospective before-after intervention analysis in an urban hospital. Reorganization of the acute ischemic stroke treatment process was carried out in 2013. We evaluated time delay, symptomatic intracerebral hemorrhage, and clinical recovery of patients before and after the reorganization. We used multivariable linear regression to estimate the change in door-to-needle time before and after the reorganization., Results: A total of 107 patients with comparable data were treated with tissue plasminogen activator in 2009 to 2012 (group 1) and 46 patients were treated during 12 months in 2013 to 2014 (group 2). Median door-to-needle time was 54 minutes before the reorganization and 20 minutes after it (statistical estimate of difference 32 minutes; 95% confidence interval 26 to 38 minutes). After adjusting for several potential cofounders in multivariable regression analysis, the only factor contributing to a significant reduction in delay was group (after reorganization versus before). Median onset-to-treatment times were 135 and 119 minutes, respectively (statistical estimate of difference 23 minutes; 95% confidence interval 6 to 39 minutes). The rates of symptomatic intracerebral hemorrhage were 4.7% (5/107) and 2.2% (1/46), respectively (difference 2.5%; 95% confidence interval -8.7% to 9.2%). Approximately 70% of treated patients were functionally independent (modified Rankin Scale score 0 to 2) when treated after the reorganization., Conclusion: Implementation of a stroke protocol with emergency physician-directed acute care decreased both door-to-needle time and onset-to-treatment time without increasing the rate of symptomatic intracerebral hemorrhage., (Copyright © 2018 American College of Emergency Physicians.

Background: The aim of this study was to compare acute effects of turnip rapeseed oil rich with mono- and polyunsaturated fatty acids and cream on postprandial triglyceride levels and post-glucose load measures of insulin sensitivity in population of men with metabolic syndrome., Methods: This open-label balanced crossover study included 37 men with metabolic syndrome. They underwent an oral glucose-fat tolerance test where they ingested 75 g of glucose with either 240 mL of cream or 84 mL of turnip rapeseed oil depending on the study arm. Hourly postprandial blood samples were drawn up to 5 h after this oral glucose-fat tolerance test to determine the changes in triglyceride concentrations and to measure insulin sensitivity. Changes in insulin sensitivity were calculated with different insulin sensitivity indices (OGIS, Stumvoll, Gutt and McAuley scores) derived from measured insulin and glucose concentrations. The oral glucose-fat tolerance test was preceded by a period during which the participants consumed a daily portion of either 35 mL of turnip rapeseed oil or 37.5 g of butter depending on the study arm in addition to their habitual diets. Both dietary periods lasted from 6 to 8 weeks. After an 8-week wash-out period the subjects crossed over to the other study arm and underwent the same process with the other fat adjunct., Results: The area under the curve for hourly triglyceride concentrations was 16% smaller after turnip rapeseed oil than after cream (13.86 [interquartile range 8.54] vs. 16.41 [9.09] mmol/l, p < 0.001). The insulin sensitivity markers of OGIS (324 [38.97] vs. 377 [68.38] p < 0.001), Stumvoll score (0.079 [0.029] vs. 0.085 [0.029], p = 0.038) and Gutt score (67.0 ± 2.78 vs. 78.8 ± 4.97 p = 0.001) were higher after turnip rapeseed oil period than after butter period. There was a non-significant change in the McAuley score., Conclusion: Dietary turnip rapeseed oil improved postprandially measured insulin sensitivity and triglyceride concentrations compared to cream and butter. This provides a possible efficient dietary mean to treat cardiovascular risk factors. Trial registration ClinicalTrials.gov NCT01119690 (05-06-2010).

After the early implementation of Emergency Medicine (EM) 25 years ago, Iceland became the first Nordic country to nationally realize the benefits of this specialty. However, the road has been rocky as in many other countries. The early years of EM in Iceland were characterized by a significant shortage of resources, particularly a lack of medical staff dedicated to EM and properly trained for the services required. The main task for the first couple of decades was to build the infrastructure of an operational emergency department based primarily on the model of EM. Although these efforts eventually led to a critical number of specialists becoming certified in EM, recruiting more people remains a priority in order to fully meet the need for specialty trained emergency physicians in Iceland. A key step towards achieving this goal was the initiation of a two-year residency program for specialty training in EM in year 2002. The program was based on a curriculum produced by the Icelandic Society for Emergency Medicine, which had been founded in year 2000. This training program is currently being redeveloped and the curriculum of the Royal College of Emergency Medicine in the UK will be adopted for use in Iceland. Another important milestone was the appointment of the first faculty member dedicated to EM at the University of Iceland. This created an opportunity to teach medical students EM and advance training at the graduate level. Also, conditions for scientific research in EM have been improved, following the establishment of an EM research institute in 2010.Other Nordic countries may be able to benefit from lessons learned and experiences gained from the development of emergency medicine in Iceland during the past quarter of a century.

We have earlier reported the reduction of total cholesterol, low-density lipoprotein (LDL) cholesterol and oxidized LDL caused by short-term modification of diet with cold-pressed turnip rapeseed oil (CPTRO) instead of butter. The aim of this supplementary study was to determine whether the beneficial effects resulted from altered cholesterol metabolism during the intervention.Thirty-seven men with metabolic syndrome (MetS) completed an open, randomized and balanced crossover study. Subjects' usual diet was supplemented with either 37.5 g of butter or 35 mL of CPTRO for 6-8 weeks. Otherwise normal dietary habits and physical activity were maintained without major variations. Serum non-cholesterol sterols were assayed with gas-liquid chromatography and used as surrogate markers of whole-body cholesterol synthesis and absorption efficiency. Serum proprotein convertase subtilisin/kexin type 9 (PCSK9) concentration was analyzed with Quantikine ELISA Immunoassay. Serum cholesterol synthesis markers and serum cholestanol (absorption marker), all as ratios to cholesterol, did not differ between the periods. Serum campesterol and sitosterol ratios to cholesterol were significantly increased after the administration of CPTRO resulting from the increased intake of 217 mg/day of plant sterols in CPTRO. Serum PCSK9 concentration did not differ between CPTRO and butter periods.The reduction in serum cholesterol by 7.2% after consumption of rapeseed oil could not be explained by changes in cholesterol absorption, synthesis or PCSK9 metabolism in MetS.ClinicalTrials.gov NCT01119690., Competing Interests: Competing interests: None declared., (© American Federation for Medical Research (unless otherwise stated in the text of the article) 2018.

Aims: Although obesity is a risk factor for coronary heart disease (CHD), it might be associated with a favourable prognosis in patients with CHD. The aim of the study was to evaluate this so called 'obesity paradox' during a follow-up period of 20 years in patients who had undergone coronary artery bypass grafting (CABG)., Methods and Results: The study population consisted of 922 CHD patients who had undergone CABG between 1993 and 1994. Pre and perioperative data was collected from patient records and supplemented with patient questionnaires, telephone contacts and data from national archives. The 10-year postoperative prognosis of normal-weight patients (body mass index (BMI) 18.5-24.9 kg/m 2 ) was inferior to that of overweight (BMI 25.0-29.9 kg/m 2 ) and obese patients (BMI⩾30.0 kg/m 2 ) and to the background population. Beyond 10 years the prognosis of obese patients deteriorated when compared with the overweight group. At the end of the 20-year follow-up, survival of the normal weight group was 0.68 (95% confidence interval (CI), 0.49-0.87; p<0.001), the overweight group 0.82 (95% CI, 0.71-0.92; p<0.001), and the obese group 0.67 (95% CI, 0.49-0.85; p<0.001), when compared with their background populations (=1.00). Obese patients developed diabetes more frequently and died more frequently of cardiovascular disease than patients in the two other study groups during the second postoperative decade ( p<0.01)., Conclusion: During long-term follow-up the obesity paradox seems to disappear due to progression of cardiometabolic disease in patients who have undergone CABG.

Introduction: Although metabolic syndrome (MetS) is evidently associated with the risk of cardiovascular disease (CVD), recently its use has been questioned. We studied the utility of MetS diagnosis when estimating individual CVD risk., Methods: We compared 27 fertile women with MetS and 27 counterparts without the syndrome, matched pairwise according to well-known risk factors of CVD. Pulse wave velocity (PWV) and central blood pressure (cBP) were determined noninvasively via a SphygmoCor device. Arterial compliance was measured noninvasively with an HDI/PulseWave TM CR-2000 arterial tonometer., Results: PWV (7.1 ± 2.5 versus 6.5 ± 1.1 m/s, p = .037), and both systolic (120.9 ± 12.2 versus 111.5 ± 16.0 mmHg, p = .031) and diastolic cBP (81.3 ± 8.5 versus 74.1 ± 11.2 mmHg, p = .035) were higher in the MetS group. Systemic arterial compliance values were lower in both large (15.1 ± 8.0 versus 16.1 ± 4.4 mL/mmHg × 10, p = .034) and small arteries (7.1 ± 2.5 versus 9.3 ± 3.2 mL/mmHg ×100, p = .010) in women with MetS., Conclusions: Fertile women with MetS had increased arterial stiffness, as measured by three different methods. Our results highlight the utility of MetS when revealing increased individual CVD risks in fertile-aged women. Key messages Women with MetS have increased arterial stiffness when measured by different methods. MetS is a useful clinical tool to assess increased cardiovascular risk, particularly among fertile-aged women.

Background: Gestational diabetes mellitus (GDM) has significant implications for the future health of the mother. Some clinical studies have suggested subclinical inflammation and vascular dysfunction after GDM. We aimed to study whether concentrations of high-sensitivity C-reactive protein (hsCRP), tissue inhibitor of metalloproteinase-1 (TIMP-1), matrix metalloproteinase-8 (MMP-8) and -9, as well as values of arterial stiffness differ between women with and without a history of GDM a few years after delivery. We also investigated possible effects of obesity on the results., Methods: We studied two cohorts-120 women with a history of GDM and 120 controls-on average 3.7 years after delivery. Serum concentrations of hsCRP were determined by immunonephelometric and immunoturbidimetric methods, MMP-8 by immunofluorometric assay, and MMP-9 and TIMP-1 by enzyme-linked immunosorbent assays. Pulse wave velocity (PWV) was determined using the foot-to-foot velocity method from carotid and femoral waveforms by using a SphygmoCor device. Arterial compliance was measured non-invasively by an HDI/PulseWave™CR-2000 arterial tonometer. All 240 women were also included in subgroup analyses to study the effect of obesity on the results. Multiple linear regression analyses were performed with adjustment for confounding factors., Results: PWV after pregnancy complicated by GDM was significantly higher than after normal pregnancy, 6.44 ± 0.83 (SD) vs. 6.17 ± 0.74 m/s (p = 0.009). Previous GDM was also one of the significant determinants of PWV in multiple linear regression analyses. On the other hand, compliance indices of both large (p = 0.092) and small (p = 0.681) arteries did not differ between the study cohorts. Serum TIMP-1 levels were significantly increased after previous GDM (p = 0.020). However, no differences were found in the serum levels of MMP-8, MMP-9 or hsCRP. In subgroup analyses, there were significantly higher concentrations of hsCRP (p = 0.015) and higher PWV (p < 0.001) among obese women compared with non-obese ones., Conclusions: PWV values were significantly higher after GDM compared with normoglycemic pregnancies and were associated with prolonged TIMP-1 upregulation. Cardiovascular risk factors were more common in participants with high BMI than in those with previous GDM.

Introduction: Gestational diabetes mellitus (GDM) is an indicator of future cardiovascular disease. We investigated whether sensitive biomarkers of increased cardiovascular risk differ between women with and without a history of GDM few years after pregnancy, and whether obesity affects the results., Material and Methods: We studied two cohorts - 120 women with a history of GDM and 120 controls, on average 3.7 years after delivery. Circulating concentrations of oxidized low-density lipoprotein (oxLDL) were determined by ELISA. The homeostasis model assessment of insulin resistance (HOMA-IR) index was used to estimate insulin resistance. Central blood pressure (cBP) was measured noninvasively from a radial artery pulse wave. The primary outcomes were possible differences in oxLDL, HOMA-IR or cBP between the groups. Secondly, we investigated the influence of obesity on the results, also using adjusted multiple linear regression analyses., Results: OxLDL concentrations or cBP did not differ between the two cohorts, but HOMA-IR was significantly higher in women with previous GDM than in controls, 1.3 ± 0.9 (SD) and 1.1 ± 0.9, respectively (p = 0.022). In subgroup analyses, HOMA-IR (p < 0.001), systolic (p < 0.001) and diastolic (p < 0.001) cBP were significantly higher in obese subgroups compared with non-obese ones. Body mass index was an important determinant of HOMA-IR and cBP in multiple linear regression analyses., Conclusions: Over 3 years after delivery, women with GDM were still more insulin-resistant than controls. Obesity turned out to be a more important determinant of insulin resistance and cBP compared with GDM., (© 2016 Nordic Federation of Societies of Obstetrics and Gynecology.)

Background: To assess whether the use of point-of-care testing (POCT) and early assessment team (EAT) model shortens emergency department (ED) length of stay (LOS)., Methods: This prospective, observational study with comparison between three study periods was performed in three phases in a metropolitan ED with 57,000 annual visits. Data were collected from adult ambulatory patients who were discharged home. Phase 1 served as a control (n = 1559 in one month). In phase 2, a comprehensive POCT panel including complete blood count, sodium, potassium, glucose, C-reactive protein, creatinine, alkaline phosphatase, alanine aminotransferase, bilirubin, amylase, and D-dimer was launched (n = 1442 in one month). In phase 3 (n = 3356 in subsequent two months), POCT approach continued. In addition, the working process was changed by establishing an EAT consisting of an emergency medicine resident and a nurse. The team operated from 12 noon to 10 p.m. was. The primary outcome was LOS (hh:mm) in the ED. Waiting times for patients requiring laboratory testing were analysed also, including time from admission to laboratory blood sampling (A2S interval), time from blood sampling to results ready (S2R interval) and time from results to discharge (R2D interval)., Results: Median LOS of patients requiring laboratory tests in phase 1 was 3:51 (95 % confidence interval 03:38-04:04). During phase 2, introduction of POCT reduced median LOS by 29 min to 03:22 (03:12-03:31, p = 0.000). In phase 3, the EAT model reduced median LOS further by 17 min to 03:05 (02:59-03:12, p = 0.033). Altogether, the process was expedited by 46 min compared with the phase 1. Surprisingly, A2S interval was unaffected by the interventions among all patients needing laboratory testing. In comparison to phase 1, shortening of S2R interval was observed in phase 2 and 3, and that of R2D interval in all patients with laboratory assessments in phase 3., Discussion: The present study included adult ambulatory patients and is the first one to examine the impact of comprehensive POC test panel, first alone and then with additional process change. As a result, LOS was reduced significantly for patients needing laboratory tests. Considerable shortening in LOS came from introduction of POCT, and EAT process decreased the LOS further. We used a comprehensive POC test panel in order to maximise the patient population benefiting from the positive impacts of POC on laboratory turnaround time and length of stay. In EAT, diverse setups exist, and these differences affect the interpretation of results. The process changes in phase 3 were done by rearranging work shifts and no extra resources were added. Regarding to staffing the process improvement was thus cost neutral., Conclusions: The advantage of POCT alone compared with central laboratory seemed to lie in shorter waiting times for results and earlier discharge home. Moreover, POCT and EAT model shorten LOS additively compared with conventional processes. However, a longer time is seemingly needed to adopt a new working process in the ED, and to establish its full benefit.

Background: Acute abdominal pain is one of the most frequent complaints evaluated at emergency departments. Approximately 25 % of abdominal pain patients discharged from emergency departments are diagnosed with undifferentiated abdominal pain. One possible reason for acute abdominal pain is renal infarction. Diagnosis is difficult and often late., Case Presentation: A white, 33-year-old, previously healthy Finnish man came to our emergency department because of acute abdominal pain. After evaluation and follow-up he was discharged the next day with a diagnosis of undifferentiated abdominal pain. He returned a day later and was diagnosed with renal infarction. Appropriate therapy was initiated in the nephrology ward. Further tests confirmed a diagnosis of renal infarction as a result of fibromuscular dysplasia. He recovered well and was discharged on the tenth day of hospitalization. His renal function was normal., Conclusions: Renal infarction is rare and should be considered if a patient with intense flank pain has no sign of urolithiasis or pyelonephritis. Contrast-enhanced computer tomography and assay of lactate dehydrogenase are recommended. The optimal treatment is still uncertain. Every patient discharged with undifferentiated abdominal pain should be given clear instructions as to when it is necessary to return to the emergency department.

Background: Tissue plasminogen activator (tPA) treatment for acute ischaemic stroke (AIS) should be given as soon as possible, preferably within 60 min after arrival at hospital. There is great variation in door-to-needle times (DNTs) internationally, nationally and even within the same hospital. Various strategies for improving treatment delays have been presented. The role of emergency physicians (EPs) in treating AIS has been under discussion in recent years. Emergency Medicine (EM) officially became a specialty in Finland in 2013. Practical education of EPs in Kanta-Häme Central Hospital began in October 2012, together with reorganization of the in-hospital treatment path for AIS patients. The main change was shifting the on-call duty regarding stroke patients from internists or neurologists to EPs after the third quarter of 2013., Methods: This was a retrospective study. The data, concerning the characteristics of tPA-treated patients, DNTs and onset-to-treatment times (OTTs) was collected from electronic and paper records. The period studied was 1 year before and 1 year during reorganization, i.e. 2012 and 2013., Results: During the study period a total of 64 tPA treatments were given, 31 before and 33 during reorganization. The median DNT was 54 min in 2012, while it was 28 min in 2013 (p < 0.001). The median OTTs were 139 and 101 min before and during the start of reorganization, respectively (p < 0.001)., Conclusions: Both total and in-hospital delays in the treatment of ischaemic stroke were shortened significantly during reorganization. Emergency physicians are able to treat AIS patients within international time guidelines. Success was based on scrutinized reorganization and good cooperation between neurologists, EPs and radiologists.

Emergency ultrasound (US) offers additive value in the diagnosis and treatment of emergency and/or critically ill patients. Emergency Medicine (EM) became a new specialty in Finland in the beginning of 2013. Since then, the training of emergency US has dramatically increased. We discuss the current situation of emergency US as a part of specialist training of EM in Finland and compare it with that in the United States and Canada. Practical indications, limitations and future prospects of emergency US are also presented.

Emergency Medicine with a six-year specialist training became a main specialty in Finland in the beginning of 2013. Specialist training has developed very quickly over just a few years. In the frontline clinics, the clinical results have already reached high international quality. When developing a new specialty, not only active research and high-quality training but also good co-operation with other specialties are of utmost importance.

Background: Women with gestational diabetes mellitus (GDM) are at an increased risk of developing metabolic syndrome (MetS) after delivery. Recently, the prevalence of both GDM and MetS has increased worldwide, in parallel with obesity. We investigated whether the presentation of MetS and its clinical features among women with previous GDM differs from that among those with normal glucose tolerance during pregnancy, and whether excess body weight affects the results., Methods: This hospital-based study of two cohorts was performed in Kanta-Häme Central Hospital, Finland. 120 women with a history of GDM and 120 women with a history of normal glucose metabolism during pregnancy, all aged between 25 and 46 were enrolled. They all underwent physical examination and had baseline blood samples taken. All 240 women were also included in subgroup analyses to study the effect of excess body weight on the results., Results: Although the groups did not differ in body mass index (BMI; p = 0.069), the risk of developing MetS after pregnancy complicated by GDM was significantly higher than after normal pregnancy, 19 vs. 8 cases (p  =  0.039). Fasting glucose (p < 0.001) and triglyceride levels (p < 0.001) were significantly higher in women affected. In subgroup analysis, cardiovascular risk factors were more common in participants with high BMI than in those with previous gestational diabetes., Conclusions: The risk of MetS was 2.4-fold higher after GDM than after normal pregnancy. Cardiovascular risk factors were more common in participants with high BMI than in those with previous GDM. Multivariate analysis supported the main findings. Weight control is important in preventing MetS after delivery.

Background: The associations of metabolic syndrome (MetS) or diabetes mellitus (DM) on long-term survival after coronary artery bypass grafting (CABG) have not been extensively evaluated. The aim of the present study was to assess the impact of MetS and DM on the 16-year survival after CABG., Methods: Diabetic and metabolic status together with relevant cardiovascular data was established in 910 CABG patients operated in 1993-94. They were divided in three groups as follows: neither DM nor MetS (375 patients), MetS alone (279 patients) and DM with or without MetS (256 patients). The 16-year follow-up of patient survival was carried out using national health databases. The relative survival rates were analyzed using the Life Table method comparing the observed survival rates of three patient groups to the rates based on age-, sex- and time-specific life tables for the whole population in Finland. To study the independent significance of MetS and DM for clinical outcome, multivariate analysis was made using an optimizing stepwise procedure based on the Bayesian approach., Results: Bayesian multivariate analysis revealed together six variables to predict clinical outcome (2 months to 16 years) in relation to the national background population, i.e. age, diabetes, left ventricular ejection fraction, BMI, perfusion time during the CABG and peripheral arterial disease. Our principal finding was that after postoperative period the 16-year prognosis of patients with neither DM nor MetS was better than that of the age-, sex-and time-matched background population (relative survival against background population 1.037, p < 0.0001). The overall survival of MetS patients resembled that of the matched background population (relative survival 0.998, NS). DM was associated with significantly increased mortality (relative survival 0.86, p < 0.0001). Additionally, mortality was even higher in patients receiving insulin treatment than in those without. Excess death rate of DM patients was predominantly caused by cardiovascular causes., Conclusion: In this long-term follow-up study patient groups without diabetes had at least equal 16 years' survival after CABG than their matched background populations. Survival of DM patients started to deteriorate already few years after the operation.

Emergency Medicine (EM) was established as a speciality in Finland in the beginning of 2013. The training period of six years conforms to the principles of the European Curriculum for EM. We present here the first-year training in Kanta-Häme Central Hospital, located in Southern Finland. Training is not only based on "learning by doing". Lunchtime lectures covering a wide variety of topics in EM are an essential part of our weekly education day. This day also offers to the residents small group sessions with abstracts, case reports, focused lectures and ultrasound training. A successful training program of EM is achievable by good collaboration with other specialities.

Background: The aim of this study was to assess nurses' self-reported confidence in their professional skills before and after an extensive Emergency Department (ED) reform in Kanta-Häme Central Hospital., Methods: Emergency nurses participated in transitional training commencing two years before the establishment of the new organization in 2007. Training was followed by weekly practical educational sessions in the new ED. During this process nurses improved their transition skills, defined house rules for the new clinic and improved their knowledge of new technology and instruments. The main processes involving critically ill ED patients were described and modelled with an electronic flow chart software.During the transitional training nurses compiled lists of practical skills and measures needed in the ED. These were updated after feedback from physicians in primary and secondary care and head physicians in Kanta-Häme Central Hospital. The final 189-item list comprised 15 different categories, each containing from 4 to 35 items. Based on the work described above, a questionnaire was developed to reflect ED nurses' skills in clinical measures but also to estimate the need for professional education and practical training. Nurses working in the ED were asked to fill the questionnaire in January 2007 (response rate 97%) and in January 2011 (response rate 98%)., Results: Nurses' self-reported confidence in their professional skills improved significally in eight classes out of fifteen. These classes were cannulations, urinary catheterizations, patient monitoring, cardiac patients, equipment, triage and nurse practising, psychiatric patients as well as infection risk. Best results were noted in urinary catheterizations, patient monitoring and infection risk. When studying the group of nurses participating in both surveys in 2007 and 2011, improvements were observed in all fifteen categories. All but two of these changes were significant (p<0.05)., Conclusions: During an extensive reform of emergency services, we noted a significant improvement in the professional skills of nurses. This improvement was especially consistent among nurses working in the ED during the whole transition process. Nurses' education and training program in the ED may be successfully put into practice when based on co-operation between nurses and physicians dedicated to emergency services.

The purpose of this work is to study the effect of a tilt table test procedure on ballistocardiographic (BCG) signal by using Electromechanical Film (EMFi) strip sensors. The ECG, BCG, carotid pulse (CP) from the neck near the carotid artery and ankle pulse signals were recorded from 7 persons. The spectral components of the recordings during the tilt table test were studied concentrating mainly on heart induced pulsatile signals propagating along the artery to the periphery. The properties of BCG pulse signal changed due to the tilt test in spectral domain. Blood pressure (BP) values and shape of the pulse changed due to the tilt test. According to this study, local BCG measurements with EMFi sensor strips combined with a tilt test can be used as a very simple non-invasive method in hemodynamic studies.

Background: SCORE and FINRISK models are designed to estimate patient's risk for cardiovascular diseases (CVD). Increased circulating oxidized LDL (oxLDL) and impaired arterial elasticity, on their part, are considered as markers of subclinical atherosclerosis. Subjects with metabolic syndrome (MetS) are thought to be at high risk for CVD because of metabolic abnormalities., Aim: To study among men with MetS whether subjects with three, four, or five MetS variables or different estimated 10-year CVD risk differ in oxLDL and arterial elasticity., Methods: OxLDL was assessed by a capture ELISA and arterial elasticity by a radial artery tonometer among 120 men with MetS. Ten-year CVD risk was calculated for those without CVD or statin medication by FINRISK and SCORE at the actual age and at the extrapolated age of 60. Results. High-risk subjects by FINRISK and SCORE had impaired arterial elasticity. In addition, high-risk subjects by FINRISK at the extrapolated age had elevated oxLDL levels. The number of MetS variables did not associate with arterial elasticity or oxLDL., Conclusion: Among men with MetS, estimation of 10-year CVD risk, especially when extrapolated to age 60, seems to differentiate subjects with respect to markers of subclinical atherosclerosis.

Short and long-term alterations of ballistocardiographic parameters (BCG) were studied in a sitting position using Electromechanical Film (EMFi) sensors. Several physiological parameters were recorded from 48 men of middle age in consecutive recordings and after a 2-week interval. The duration and amplitudes of the signal components were studied. The repeatability index R, the Pearson correlation, and Bland-Altman (BA) repeatability methods were used to determine how repeatable the studied signals are. In consecutive and during 2 week recordings, the Pearson correlation rates for BCG systolic component values (from 0.88/0.83 (T(RJ)) to 0.97/0.78 (A(IJ)), PWV values for the left 0.97/0.67 and right ankle 0.98/0.76) were detected indicating excellent repeatability during consecutive recordings. Respectively BA T(RJ) was -0.002 ± 0.028/-0.004 ± 0.030. Corresponding R values were T(RJ) 0.90/0.82 and right ankle PWV 0.98/0.81. Quite modest blood pressure R values were obtained between 2 week recordings (systolic 0.63, diastolic 0.75, and heart rate 0.59). BCG and PWV measured with EMFi sensors are highly repeatable in consecutive recordings. In longer time interval recordings, BCG is influenced by hemodynamic instability, but in spite of this the reproducibility of the main parameters of the BCG and PWV were better than measured heart rate and blood pressure values.

Background: Erectile dysfunction (ED), impaired arterial elasticity, elevated resting heart rate as well as increased levels of oxidized LDL and fibrinogen associate with future cardiovascular events. Physical activity is crucial in the prevention of cardiovascular diseases (CVD), while metabolic syndrome (MetS) comprises an increased risk for CVD events. The aim of this study was to assess whether markers of subclinical atherosclerosis are associated with the presence of ED and MetS, and whether physical activity is protective of ED., Methods: 57 MetS (51.3 ± 8.0 years) and 48 physically active (PhA) (51.1 ± 8.1 years) subjects participated in the study. ED was assessed by the International Index of Erectile Function (IIEF) questionnaire, arterial elasticity by a radial artery tonometer (HDI/PulseWave™ CR-2000) and circulating oxLDL by a capture ELISA immunoassay. Fibrinogen and lipids were assessed by validated methods. The calculation of mean daily energy expenditure of physical exercise was based on a structured questionnaire., Results: ED was more often present among MetS compared to PhA subjects, 63.2% and 27.1%, respectively (p < 0.001). Regular physical exercise at the level of > 400 kcal/day was protective of ED (OR 0.12, 95% CI 0.017-0.778, p = 0.027), whereas increased fibrinogen (OR 4.67, 95% CI 1.171-18.627, p = 0.029) and elevated resting heart rate (OR 1.07, 95% CI 1.003-1.138, p = 0.04) were independently associated with the presence of ED. In addition, large arterial elasticity (ml/mmHgx10) was lower among MetS compared to PhA subjects (16.6 ± 4.0 vs. 19.6 ± 4.2, p < 0.001), as well as among ED compared to non-ED subjects (16.7 ± 4.6 vs. 19.0 ± 3.9, p = 0.008). Fibrinogen and resting heart rate were highest and large arterial elasticity lowest among subjects with both MetS and ED., Conclusions: Markers of subclinical atherosclerosis associated with the presence of ED and were most evident among subjects with both MetS and ED. Thus, especially MetS patients presenting with ED should be considered at high risk for CVD events. Physical activity, on its part, seems to be protective of ED., Trial Registration: ClinicalTrials.gov NCT01119404.

Antithrombotic effects of statins are based on two main phenomenons. Statins have the ability to strengthen a vulnerable plaque as well as to downregulate blood coagulation and platelet function. The latter seem to be mediated through the inhibition of the mevalonate pathway and especially the isoprenylation of signalling proteins. In clinical studies, statins decrease the risk of both arterial atherothrombosis and venous thromboembolism. According to recent clinical data, antithrombotic effects of statin therapy take place promptly. It is therefore justifiable to use immediate and potent statin medication in the patients with an acute coronary syndrome and/or percutaneous coronary intervention. Although the new results on the prevention of venous thrombosis are promising, evidence-based antithrombotic therapy should not be substituted by statin medication.

Background: Rapeseed oil is the principal dietary source of monounsaturated and n-3 polyunsaturated fatty acids in the Northern Europe. However, the effect of rapeseed oil on the markers of subclinical atherosclerosis is not known. The purpose of this study was to compare the effects of dietary intake of cold-pressed turnip rapeseed oil (CPTRO) and butter on serum lipids, oxidized LDL and arterial elasticity in men with metabolic syndrome., Methods: Thirty-seven men with metabolic syndrome completed an open and balanced crossover study. Treatment periods lasted for 6 to 8 weeks and they were separated from each other with an eight-week washout period. Subjects maintained their normal dietary habits and physical activity without major variations. The daily fat adjunct consisted either of 37.5 grams of butter or 35 mL of Virgino R CPTRO. Participants were asked to spread butter on bread on the butter period and to drink CPTRO on the oil period. The fat adjunct was used as such without heating or frying., Results: Compared to butter, administration of CPTRO was followed by a reduction of total cholesterol by 8% (p < 0.001) and LDL cholesterol by 11% (p < 0.001). The level of oxidized LDL was 16% lower after oil period (p = 0.024). Minimal differences in arterial elasticity were not statistically significant., Conclusion: Cold-pressed turnip rapeseed oil had favourable effects on circulating LDL cholesterol and oxidized LDL, which may be important in the management of patients at high cardiovascular risk.

Background: Accumulation of oxidized low-density lipoproteins in the intimae of arteries and endothelial dysfunction are key events in the development of atherosclerosis. Patients with metabolic syndrome are at high risk for cardiovascular diseases but the linkage between metabolic syndrome and atherosclerosis is incompletely understood. We studied whether the levels of oxidized LDL and arterial elasticity differ between metabolic syndrome patients and physically active controls., Methods: 40 men with metabolic syndrome and 40 physically active controls participated in this cross-sectional study. None of the study subjects had been diagnosed with cardiovascular disease. Levels of oxidized LDL were assessed by a two-site ELISA immunoassay. Arterial elasticity was assessed non-invasively by the HDI/PulseWave CR-2000 arterial tonometer., Results: Levels of oxidized LDL were 89.6 +/- 33.1 U/L for metabolic syndrome subjects and 68.5 +/- 23.6 U/L for controls (p = 0.007). The difference remained significant after adjustment for LDL cholesterol. Large artery elasticity index (C1) was 16.2 +/- 4.1 mL/mmHgx10 for metabolic syndrome subjects and 19.4 +/- 3.7 mL/mmHgx10 for controls (p = 0.001), small artery indices (C2) were 7.0 +/- 3.2 mL/mmHgx100 and 6.5 +/- 2.9 mL/mmHgx100 (NS), respectively., Conclusions: Subjects with metabolic syndrome had elevated levels of oxidized LDL and reduced large arterial elasticity compared to controls. This finding may partly explain the increased risk for cardiovascular diseases among metabolic syndrome patients., Trial Registration: ClinicalTrials.gov NCT01114763.

Objectives: To establish which factors influence patients' return to work and how well they remain at work after coronary artery bypass grafting (CABG)., Design: Five hundred and sixty nine consecutive CABG patients aged less than 65 years were followed for 10 years. Data were collected from patient records and by questionnaires supplemented with information from Finnish national archives., Results: Multivariate analysis showed the best predictors for return to work to be younger age, preoperative working, as well as absence of diabetes or perioperative cardiac damage. Almost half of the patients aged less than 60 and preoperatively not retired were working one year after CABG. Five years postoperatively, 85% of patients younger than 60 years and once returned to work were still working. Correspondingly, of subjects remaining under 60 years during a 10-year follow-up, 75% continued working., Conclusions: Younger age and preoperative employment were the most important predictors of successful return to work. Once returned after CABG, patients' staying at work was comparable with that in the general population.

Background: Comprehensive preventive education for heart patients is effective in reducing cardiac events. However, very demanding counselling protocols cannot easily be implemented as an integral part of clinical practice in hospitals., Aim: To evaluate whether recurrent preventive group education for coronary artery bypass grafting patients affects the resistance of LDL against oxidation and the classical risk factors for coronary heart disease., Methods: A prospective, controlled study with one-year follow-up was carried out in Southern Finland. Coronary artery bypass patients were allocated late (> or = 18 months) after the operation in the intervention and control groups., Results: Seventy two patients (65 men and 7 women) completed the study. Twelve-hour group education on healthy life-style had a significant (25%, P = 0.01) but transient positive effect on the resistance of LDL against oxidation. There was a trend towards increased physical activity in the intervention group. The impact of education on patients' weight was also more consistent (1.2 kg at 12 months, P < 0.05), whereas long-term effects on fibrinogen and serum lipids were small., Conclusions: Repeated group education applied as an economically feasible part of specialist care had only small positive effects on patients' risk factors. There was a significant, but transient, increase in the resistance of LDL against oxidation. However, effective lipid lowering drug treatment is indicated for most coronary artery bypass patients rather than repeated health education alone.
