Matematikk og kommunikasjon – en kraftig kombinasjon? En kvalitativ studie av elevers kommunikasjon i et Tenkende klasserom

Denne studiens tema er elevkommunikasjon under implementeringen av Tenkende klasserom. Gjennom en kvalitativ studie utviklet vi et rammeverk bestående av ti kategorier elevutsagn: korte svar og påstander, argumenter, utfordringer, evalueringer og avklaringer, forklaringer, spørsmål, forslag, resonnementer, kommentarer og ikke-faglig. Videre har vi sett på hvor ofte hver type utsagn oppsto blant tre elevgrupper i en Tenkende klasserom-undervisning, samtidig som vi har elevkommunikasjonens grad av utforsking. Våre funn tyder på at tilnærmet 40% av elevenes utsagn var av lav utforskingsgrad, 31% var av middels utforskende grad, og omtrent 21% av elevutsagnene hadde høy grad av utforsking. Studien viser at anvendelse av Tenkende klasserom-rammeverket ser ut til å tilrettelegge for utforskende kommunikasjon blant elever. Samtidig indikerer studien også at kulturen og normene som tilhører et Tenkende klasserom ikke umiddelbart blir fullt etablert. Elevene vi observerte bar preg av lite erfaring med denne undervisningstilnærmingen, noe som ble reflektert i måten de kommuniserte med hverandre på

Gender- and age-related differences in clinical presentation and management of outpatients with stable coronary artery disease

<br>Introduction: Contemporary generalizable data on the demographics and management of outpatients with stable coronary artery disease (CAD) in routine clinical practice are sparse. Using the data from the CLARIFY registry we describe gender- and age-related differences in baseline characteristics and management of these patients across broad geographic regions.</br> <br>Methods: This international, prospective, observational, longitudinal registry enrolled stable CAD outpatients from 45 countries in Africa, Asia, Australia, Europe, the Middle East, and North, Central, and South America.</br> <br>Results: Baseline data were available for 33 280 patients. Mean (SD) age was 64 (10.5) years and 22.5% of patients were female. The prevalence of CAD risk factors was generally higher in women than in men. Women were older (66.6 vs 63.4 years), more frequently diagnosed with diabetes (33% vs 28%), hypertension (79% vs 69%), and higher resting heart rate (69 vs 67 bpm), and were less physically active. Smoking and a history of myocardial infarction were more common in men. Women were more likely to have angina (28% vs 20%), but less likely to have undergone revascularization procedures. CAD was more likely to be asymptomatic in older patients perhaps because of reduced levels of physical activity. Prescription of evidence-based medication for secondary prevention varied with age, with patients ≥ 75 years treated less often with beta blockers, aspirin and angiotensin-converting enzyme inhibitors than patients < 65 years.</br> <br>Conclusions: Important gender-related differences in clinical characteristics and management continue to exist in all age groups of outpatients with stable CAD.</br&gt

Outcomes after coronary angiography for unstable angina compared to stable angina, myocardial infarction and an asymptomatic general population

Background: The outcomes of real-world unstable angina (UA) in the high-sensitivity troponin era are unclear. We aimed to investigate the outcomes of UA referred to coronary angiography compared to stable angina (SA), nonST-segment elevation myocardial infarction (NSTEMI), STEMI and a general population. Methods: We included the 9,694 patients with no prior coronary artery disease (CAD) referred to invasive or CT coronary angiography from 2013 to 2018 in Northern Norway (51% SA, 12% UA, 23% NSTEMI and 14% STEMI), and 11,959 asymptomatic individuals recruited from the Tromsø Study. We used Cox models to estimate the hazard ratios (HR) for all-cause mortality and major adverse cardiovascular events (MACE), defined as cardiovascular death, MI or obstructive CAD. Results: The median follow-up time was 2.8 years. The incidence rate of death was 8.5 per 1000 person-years (95 % confidence interval [CI] 8.0–9.0) in the general population, 9.7 (95 % CI 8.3–11.5) in SA, 14.9 (95 % CI 11.4–19.6) in UA, 29.7 (95 % CI 25.6–34.3) in NSTEMI and 36.5 (95 % CI 30.9–43.2) in STEMI. In multivariable adjusted analyses, compared with UA, SA had a 38 % lower risk of death and a non-significant lower risk of MACE (HR 0.62, 95 % CI 0.44–0.89; HR 0.86, 95 % CI 0.66–1.11). NSTEMI had a 2.4-fold higher risk of death (HR 2.39, 95 % CI 1.38–4.14) and a 1.6-fold higher risk of MACE (HR 1.62, 95 % CI 1.11–2.38) compared tox UA during the first year after coronary angiography, but a similar risk thereafter. There was no difference in the risk of death for UA with non-obstructive CAD and obstructive CAD (HR 0.78, 95 % CI 0.39–1.57). Conclusion: UA had a higher risk of death but a similar risk of MACE compared to SA and a lower 1-year risk of death and MACE compared to NSTEMI

Secondly, we are deeply thankful to Tor-Elesh Albrigtsen for the remarkable assistance with data science, analysis and programming in Python.Publication status: PublishedFunder: Science for Life Laboratory; doi: http://dx.doi.org/10.13039/501100009252; Grant(s): ZSC – National core facility for pandemic preparednessFunder: Scandinavian Society for Antimicrobial Chemotherapy Foundation; doi: http://dx.doi.org/10.13039/501100011777; Grant(s): SLS-961049Funder: Erik, Karin and Gösta Selander Foundation; Grant(s): 2022Funder: Regionala Forskningsrådet Uppsala/Örebro; doi: http://dx.doi.org/10.13039/100019032; Grant(s): RFR-930984Funder: Uppsala UniversityAbstract: Background: Since the beginning of the COVID-19 pandemic, new variants of significance to public health have emerged. Consequently, early detection of new mutations and variants through whole-genome sequencing remains crucial to assist health officials in employing appropriate public health measures. Methods: We utilized the ARTIC Network SARS-CoV-2 tiled amplicon approach and Nanopore sequencing to sequence 4,674 COVID-19 positive patient samples from Uppsala County, Sweden, between week 15 and 52 in 2021. Using this data, we mapped the circulating variants of concern (VOC) in the county over time and analysed the Spike (S) protein mutational dynamics in the Delta variant throughout 2021. Results: The distribution of the SARS-CoV-2 VOC matched the national VOC distribution in Sweden, in 2021. In the S protein of the Delta variant, we detected mutations attributable to variants under monitoring and variants of interest (e.g., E484Q, Q613H, Q677H, A222V and Y145H) and future VOC (e.g., T95I and Y144 deletion, which are signature mutations in the Omicron variant). We also frequently detected some less well-described S protein mutations in our Delta sequences, that might play a role in shaping future emerging variants. These include A262S, Q675K, I850L, Q1201H, V1228L and M1237I. Lastly, we observed that some of the Delta variant’s signature mutations were underrepresented in our study due to artifacts of the used bioinformatics tools, approach and sequencing method. We therefore discuss some pitfalls and considerations when sequencing SARS-CoV-2 genomes. Conclusion: Our results suggest that genomic surveillance in a small, representative cohort can be used to make predictions about the circulating variants nationally. Moreover, we show that detection of transient mutations in currently circulating variants can give valuable clues to signature mutations of future VOC. Here we suggest six such mutations, that we detected frequently in the Delta variant during 2021. Lastly, we report multiple systematic errors that occurred when following the ARTIC Network SARS-CoV-2 tiled amplicon approach using the V3 primers and Nanopore sequencing, which led to the masking of some of the important signature mutations in the Delta sequences

Long-term results after simple versus complex stenting of coronary artery bifurcation lesions:nordic bifurcation study 5-year follow-up results

ObjectivesThis study sought to report the 5-year follow-up results of the Nordic Bifurcation Study.BackgroundRandomized clinical trials with short-term follow-up have indicated that coronary bifurcation lesions may be optimally treated using the optional side branch stenting strategy.MethodsA total of 413 patients with a coronary bifurcation lesion were randomly assigned to a simple stenting strategy of main vessel (MV) and optional stenting of side branch (SB) or to a complex stenting strategy, namely, stenting of both MV and SB.ResultsFive-year clinical follow-up data were available for 404 (98%) patients. The combined safety and efficacy endpoint of cardiac death, non–procedure-related myocardial infarction, and target vessel revascularization were seen in 15.8% in the optional SB stenting group as compared to 21.8% in the MV and SB stenting group (p = 0.15). All-cause death was seen in 5.9% versus 10.4% (p = 0.16) and non–procedure-related myocardial infarction in 4% versus 7.9% (p = 0.09) in the optional SB stenting group versus the MV and SB stenting group, respectively. The rates of target vessel revascularization were 13.4% versus 18.3% (p = 0.14) and the rates of definite stent thrombosis were 3% versus 1.5% (p = 0.31) in the optional SB stenting group versus the MV and SB stenting group, respectively.ConclusionsAt 5-year follow-up in the Nordic Bifurcation Study, the clinical outcomes after simple optional side branch stenting remained at least equal to the more complex strategy of planned stenting of both the main vessel and the side branch

Proteomic resolution of IGFN1 complexes reveals a functional interaction with the actin nucleating protein COBL

The Igfn1 gene produces multiple proteins by alternative splicing predominantly expressed in skeletal muscle. Igfn1 deficient clones derived from C2C12 myoblasts show reduced fusion index and morphological differences compared to control myotubes. Here, we first show that G:F actin ratios are significantly higher in differentiating IGFN1-deficient C2C12 myoblasts, suggesting that fusion and differentiation defects are underpinned by deficient actin remodelling. We obtained pull-downs from skeletal muscle with IGFN1 fragments and applied a proteomics approach. The proteomic composition of IGFN1 complexes identified the cytoskeleton and an association with the proteasome as the main networks. The actin nucleating protein COBL was selected for further validation. COBL is expressed in C2C12 myoblasts from the first stages of myoblast fusion but not in proliferating cells. COBL is also expressed in adult muscle and, as IGFN1, localizes to the Z-disc. We show that IGFN1 interacts, stabilizes and colocalizes with COBL and prevents the ability of COBL to form actin ruffles in COS7 cells. COBL loss of function C2C12-derived clones are able to fuse, therefore indicating that COBL or the IGFN1/COBL interaction are not essential for myoblast fusion
