Tidskriftsartikel (refereegranskat)abstract
- The three conformationally restricted cyclopropyl glutamate analogues (3, 4, 5) were synthesised and their affinity for ionotropic and activity at metabotropic glutamate receptors were probed. Compound 4 turned out to be a highly selective agonist at the metabotropic glutamate receptor mGluR2 with at least two orders of magnitude selectivity in potency compared to the very homologous mGluR3 as well as mGluR1, 4, 5, 7. We also tried to synthesise the two epimers of 6, but the two compounds underwent fast epimerisation in H2O. Furthermore, two cyclopropyl arginine analogues (7, 8) were synthesised and characterised pharmacologically at GPRC6A.

- The effects of nutrition strategy on levels of nutrients and bioactive compounds in fruit and leaves of blackberries were studied in greenhouse-grown blackberry plants fertilised with combinations of two levels (low, high) of nitrogen (60 and 100 kg ha -1, respectively) and potassium (66.4 and 104 kg ha -1, respectively). Plant concentrations of organic phytochemicals were quantitatively analysed by high-performance liquid chromatography. High amounts of both fertilisers produced high amounts of all nutrients and bioactive compounds analysed in fruit except total acidity and ellagic acid. There were major differences in compounds affecting taste in fruit, e. g., sugars (fructose and glucose), total soluble solids and pH, and also in anthocyanin content. The concentrations of secondary metabolites, vitamin C and ellagic acid in fruit also varied significantly between treatments, although the differences were smaller. Storage of blackberries showed variable effects in the different levels of compounds, and the changes found were small. Nutrient regime did not affect blackberry leaves to the same extent, and only minor changes were found. The findings show that by optimising plant nutrition, phytonutrient levels can be maximised and maintained in fresh and stored berry crops, especially those grown in greenhouses, where conditions can easily be regulated.

- Background: Chronic Obstructive Pulmonary Disease (COPD) is the fourth leading cause of death in the world. COPD is a progressive disease that could lead to chronic hypoxemia, which requires treatment as domiciliary Long-Term Oxygen Therapy (LTOT). There is a need for increased knowledge about self-care strategies used by individuals living with COPD and LTOT. Objective: The aim was to explore experiences and self-care strategies in patients living with both COPD and LTOT. Sample: The sample consisted of five men and five women diagnosed with COPD being prescribed LTOT for more than one year. Method: Ten interviews were undertaken and analyzed for both manifest and latent content. Results: Living with COPD and LTOT was associated with experiences of guilt although there were doubts about what had caused the lung disease. Both the lung disease and the oxygen therapy had a negative impact on their self-image. Anxiety was expressed when thoughts about the remaining time occurred. There was a constant balance between diminishing abilities and increasing restrictions related to the lung disease and the therapy. In order to compensate for arising imbalance, self-care strategies had been initiated aimed at preserving the present state of health, enabling and facilitating physical activity and promoting a positive attitude. Conclusion: The current study suggests that individuals living with COPD and LTOT are encouraged to adopt self-care strategies directed towards maintaining stability with regard to the lung disease, the oxygen therapy, physical capability and emotional reactions.

- OBJECTIVES: We have developed a method using transthoracic echocardiography in establishing optimal visualization of the aortic root, to reduce the amount of contrast medium used in each patient. BACKGROUND: During transcatheter aortic valve implantation, it is necessary to obtain an optimal fluoroscopic projection for deployment of the valve showing the aortic ostium with the three cusps aligned in the beam direction. This may require repeat aortic root angiograms at this stage of the procedure with a high amount of contrast medium with a risk of detrimental influence on renal function. METHODS: We studied the conventional way and an echo guided way to optimize visualisation of the aortic root. Echocardiography was used initially allowing easier alignment of the image intensifier with the transducer's direction. RESULTS: Contrast volumes, radiation/fluoroscopy exposure times, and postoperative creatinine levels were significantly less in patients having the echo-guided orientation of the optimal fluoroscopic angles compared with patients treated with the conventional approach. CONCLUSION: We present a user-friendly echo-guided method to facilitate fluoroscopy adjustment during transcatheter aortic valve implantation. In our series, the amounts of contrast medium and radiation have been significantly reduced, with a concomitant reduction in detrimental effects on renal function in the early postoperative phase.

- In this paper we look at opportunities to support the creation of value for all through the use of end-user-owned Virtual Personal Assistant. We use a chat-bot as example of technology with a possibility for transferring and diffusing new functionality, features and capabilities. This category of software can create potential value through its AI and natural language processing combined with emulation and imitation of emotional engagement which is personal, private and as such allows for intimate contextual relevance to be developed.

Tidskriftsartikel (refereegranskat)abstract
- Guidelines recommend dual antiplatelet therapy after coronary artery bypass grafting (CABG) for patients with acute coronary syndrome (ACS). However, the evidence for these recommendations is weak.To compare midterm outcomes after CABG in patients with ACS treated postoperatively with acetylsalicylic acid (ASA) and ticagrelor or with ASA monotherapy.This cohort study used merged data from several national registries of Swedish patients who were diagnosed with ACS and subsequently underwent CABG. All included patients underwent isolated CABG in Sweden between 2012 and 2017 with an ACS diagnosis less than 6 weeks before the procedure, survived 14 days after discharge from hospital, and were treated postoperatively with ASA plus ticagrelor or ASA monotherapy. A multivariable Cox regression model was used for the main analysis, and propensity score-matched models were performed as sensitivity analysis. Data were analyzed between May and September 2020.Postoperative antiplatelet treatment, defined as filled prescriptions, with either ASA and ticagrelor or ASA only.Major adverse cardiovascular events (MACE), defined as all-cause mortality, myocardial infarction, and stroke, and major bleeding, at 12 months and at the end of follow-up.A total of 6558 patients (5281 [80.5%] men; mean [SD] age at surgery, 67.6 [9.3] years) were included; 1813 (27.6%) were treated with ASA plus ticagrelor and 4745 (72.4%) were treated with ASA monotherapy. Crude MACE rate was 3.0 per 100 person years (95% CI, 2.5-3.6 per 100 person years) in the ASA plus ticagrelor group and 3.8 per 100 person years (95% CI, 3.5-4.1 per 100 person years) in the ASA group. After adjustment, there was no significant difference in MACE risk between ASA plus ticagrelor vs ASA only, neither during the first 12 months (adjusted hazard ratio [aHR], 0.84; 95% CI, 0.58-1.21; P=.34) or during total follow-up (aHR, 0.89; 95% CI, 0.71-1.11; P=.29). The use of ASA plus ticagrelor was associated with a significantly increased risk for major bleeding during the first 12 months (aHR, 1.90; 95% CI, 1.16-3.13; P=.011). Sensitivity analyses confirmed the results.In patients with ACS who survived 2 weeks after CABG, no significant difference in the risk of death or ischemic events could be demonstrated between ASA plus ticagrelor and patients treated with ASA only, while the risk for major bleeding was higher in patients treated with ASA plus ticagrelor. Sufficiently powered prospective randomized trials comparing different antiplatelet therapy strategies after CABG are warranted.

- AIMS: To evaluate the long-term use of secondary prevention medications [statins, β-blockers, renin-angiotensin-aldosterone system (RAAS) inhibitors, and platelet inhibitors] after coronary artery bypass grafting (CABG) and the association between medication use and mortality.METHODS AND RESULTS: All patients who underwent isolated CABG in Sweden from 2006 to 2015 and survived at least 6 months after discharge were included (n = 28 812). Individual patient data from SWEDEHEART and other mandatory nationwide registries were merged. Multivariable Cox regression models using time-updated data on dispensed prescriptions were used to assess associations between medication use and long-term mortality. Statins were dispensed to 93.9% of the patients 6 months after discharge and to 77.3% 8 years later. Corresponding figures for β-blockers were 91.0% and 76.4%, for RAAS inhibitors 72.9% and 65.9%, and for platelet inhibitors 93.0% and 79.8%. All medications were dispensed less often to patients ≥75 years. Treatment with statins [hazard ratio (HR) 0.56, 95% confidence interval (95% CI) 0.52-0.60], RAAS inhibitors (HR 0.78, 95% CI 0.73-0.84), and platelet inhibitors (HR 0.74, 95% CI 0.69-0.81) were individually associated with lower mortality risk after adjustment for age, gender, comorbidities, and use of other secondary preventive drugs (all P < 0.001). There was no association between β-blockers and mortality risk (HR 0.97, 95% CI 0.90-1.06; P = 0.54).CONCLUSION: The use of secondary prevention medications after CABG was high early after surgery but decreased significantly over time. The results of this observational study, with inherent risk of selection bias, suggest that treatment with statins, RAAS inhibitors, and platelet inhibitors is essential after CABG whereas the routine use of β-blockers may be questioned.
