Second Language Class Planning: The Stages of Teaching-Learning as a Means of Promoting the Feeling of Pleasure

Abstract: The present paper studies how didactic and teaching strategies can promote pleasure in students after a series of class sessions. It focuses on the teaching of English and Spanish as a foreign language in the French university system. The term pleasure is studied as students’ satisfaction regarding the teaching and the strategies planned by the teacher instead of their academic success. Our initial hypothesis is that an in-depth preparation of activities and teaching and didactic resources, in accordance with the stages of learning, helps to promote pleasure in students regardless of the language or content of the class. Based on a common planning that takes into account the teaching-learning stages (motivation/expectancy, comprehension/attention, generalization/transfer), we carry out a classroom research to corroborate our hypothesis. We selected 180 university students through a convenience sampling. A self-administered pencil-and-paper questionnaire was used for data collection, considering 6 degrees of satisfaction on a Likert scale. The questionnaire assessed three aspects: the contents, the teacher's methodology and the students' participation. The quantitative analysis of the data shows that there seems to be a relationship between strict planning and the students' feeling of pleasure during learning.

A Case of Brugada Phenocopy in Adrenal Insufficiency-Related Pericarditis

Abstract: This is a report of a 27-year-old man with known history of Addison’s disease, noncompliant with medications, and hypothyroidism who presented with shortness of breath, nausea, vomiting, fever, and chest pain as well as Brugada sign seen on electrocardiogram. Echocardiogram revealed a moderate pericardial effusion and laboratory findings were suggestive of adrenal insufficiency. Patient was determined to have Type I Brugada phenocopy, which is a Brugada sign seen on EKG with a reversible cause. In this instance, the Brugada phenocopy was caused by adrenal insufficiency with associated pericarditis. Treatment with high-dose steroids led to resolution of both the pericardial effusion and Brugada sign, providing further evidence of Brugada phenocopy.

Ventricular Tachycardia Induced by a Wandering Nephroureteral Stent

Abstract: We present a unique case of a 56-year-old female with complex cloacogenic carcinoma history who experienced intraoperative episodes of ventricular tachycardia and pulselessness of unclear etiology. The etiology was later found to be related to a nephroureteral stent that had perforated the right ureter, entered the right ovarian vein, traversed up the inferior vena cava, and nestled in the right atrium.

The Effect of Adding Procalcitonin to the Systemic Inflammatory Response Syndrome (Sirs) and Quick Sepsis-Related Organ Failure Assessment (qSOFA) Scoring System in Predicting Sepsis Mortality

Abstract: Objective: The primary objective of this study was to determine if the addition of procalcitonin to the existing systemic inflammatory response syndrome (SIRS) and quick Sepsis-related Organ Failure Assessment (qSOFA) scoring systems could improve the predictability of in-hospital sepsis-related mortality. Secondarily, we sought to determine if the addition of procalcitonin could predict the likelihood of ICU admission and discharge home. Design: This is a retrospective, single-center, observational study that looked at data from January 1, 2017 to January 1, 2019. Patients were stratified into four groups: SIRS-positive + procalcitonin >2 ng/mL (pSIRS+), SIRS-positive + procalcitonin ≤2 ng/mL (pSIRS-), qSOFA-positive + procalcitonin >2 ng/mL (pqSOFA+), and qSOFA-positive + procalcitonin ≤2 ng/mL (pqSOFA-). Setting: The study was conducted at a community hospital in Las Vegas, Nevada. Patients: Patients were included in the study if they were >18 years of age and had hospital admission diagnosis of sepsis with at least one value of procalcitonin level. Interventions: After patients which met the inclusion criteria, patients were divided into subgroups of SIRS, SIRS + procalcitonin > 2 ng/mL, qSOFA, qSOFA + procalcitonin >2 ng/mL. Primary outcomes were in-hospital mortality and secondary outcomes were ICU admission, length of stay, and discharge to home. Results: 933 patients were included in the study with an overall mortality rate of 21.22%, an overall ICU admission rate of 56.15%, and an overall discharge home rate of 29.58%. In those identified with a sepsis-related diagnosis code, pSIRS+ predicted an in-hospital mortality rate of 31.89% compared to pSIRS- 16.15% (P < 0.0001). In regards to qSOFA, the addition of procalcitonin added no statistically significant difference in predicting in-hospital mortality. pSIRS+ patients were found to have an ICU admission rate of 76.16% and a discharge home rate of 19.20% compared to pSIRS- who had 47.40% and 34.90%, respectively (P < 0.0001). Like in our primary outcome, our data for qSOFA was not statistically significant. Conclusions: Procalcitonin added utility to the SIRS scoring system in predicting sepsis-related in-hospital mortality, ICU admission, and discharge home. Procalcitonin did not add statistically significant benefit to the qSOFA scoring system in predicting sepsis-related in-hospital mortality, ICU admission, and discharge home.
