Students emotions in the ELT classroom

During our practice and observations carried out in Colegio Técnico y Académico Celestin Freinet, we were able to identify the difficulties that the students encounter at the moment of presenting an oral production activity in front of the class, reducing the amount of speaking and the quality of it, making more difficult for the students and the teacher to share their ideas, increasing the frustration that the students might feel. This proposal emerged after the experience that one of the researchers had in a previous school in which some of the students from tenth grade felt overwhelmed by their emotions and were not able to complete their oral presentations in front of the class. The students let the teachers know that fear and shame were behind the way they felt and how the previously mentioned emotions and feelings prevented them from speaking in front of the class

Protein-based cardiogenic shock patient classifier

Aims Cardiogenic shock (CS) is associated with high short-term mortality and a precise CS risk stratification could guide interventions to improve patient outcome. Here, we developed a circulating protein-based score to predict short-term mortality risk among patients with CS. Methods and results Mass spectrometry analysis of 2654 proteins was used for screening in the Barcelona discovery cohort (n = 48). Targeted quantitative proteomics analyses (n = 51 proteins) were used in the independent CardShock cohort (n = 97) to derive and cross-validate the protein classifier. The combination of four circulating proteins (Cardiogenic Shock 4 proteins-CS4P), discriminated patients with low and high 90-day risk of mortality. CS4P comprises the abundances of liver-type fatty acid-binding protein, beta-2-microglobulin, fructose-bisphosphate aldolase B, and SerpinG1. Within the CardShock cohort used for internal validation, the C-statistic was 0.78 for the CardShock risk score, 0.83 for the CS4P model, and 0.84 (P = 0.033 vs. CardShock risk score) for the combination of CardShock risk score with the CS4P model. The CardShock risk score with the CS4P model showed a marked benefit in patient reclassification, with a net reclassification improvement (NRI) of 0.49 (P = 0.020) compared with CardShock risk score. Similar reclassification metrics were observed in the IABP-SHOCK II risk score combined with CS4P (NRI =0.57; P = 0.032). The CS4P patient classification power was confirmed by enzyme-linked immuno-sorbent assay (ELISA). Conclusion A new protein-based CS patient classifier, the CS4P, was developed for short-term mortality risk stratification. CS4P improved predictive metrics in combination with contemporary risk scores, which may guide clinicians in selecting patients for advanced therapies.Peer reviewe

Circulating Omega-3 fatty acids and incident adverse events in patients with acute myocardial infarction

Background: Dietary omega-3 eicosapentaenoic acid (EPA) has multiple cardioprotective properties. The proportion of EPA in serum phosphatidylcholine (PC) mirrors dietary EPA intake during previous weeks. Circulating EPA in ST-segment elevation myocardial infarction (STEMI) relates to smaller infarct size and preserved long-term ventricular function. Objectives: The authors investigated whether serum-PC EPA (proxy for marine omega-3 consumption) levels at the time of STEMI were associated with a lower incidence of major adverse cardiovascular events (MACE), all-cause mortality, and readmission for cardiovascular (CV) causes at 3 years' follow-up. We also explored the association of alpha-linolenic acid (ALA, proxy for vegetable omega-3 intake) with all-cause mortality and MACE. Methods: The authors prospectively included 944 consecutive patients with STEMI (mean age 61 years, 209 women) undergoing primary percutaneous coronary intervention. We determined serum-PC fatty acids with gas chromatography. Results: During follow-up, 211 patients had MACE, 108 died, and 130 were readmitted for CV causes. A Cox proportional hazards model adjusted for known clinical predictors showed that serum-PC EPA at the time of STEMI was inversely associated with both incident MACE and CV readmission (hazard ratio [HR]: 0.76; 95% confidence interval [CI]: 0.62 to 0.94, and HR: 0.74; 95% CI: 0.58 to 0.95, respectively, for a 1-standard deviation [SD] increase). Serum-PC ALA was inversely related to all-cause mortality (HR: 0.65; 95% CI: 0.44 to 0.96, for a 1-SD increase). Conclusions: Elevated serum-PC EPA and ALA levels at the time of STEMI were associated with a lower risk of clinical adverse events. Consumption of foods rich in these fatty acids might improve the prognosis of STEMI
