ABSTRACT

The intricate relationship between teenagers' literacy and technology underscores the need for a comprehensive understanding, particularly in the Spanish context. This study employs explainable artificial intelligence (AI) to delve into this complex interplay, focusing on the pivotal role of reading comprehension skills in the personal and career development of Spanish teenagers. With a sample of 22,400 15-year-olds from the PISA dataset, we investigate the impact of socioeconomic factors, technology habits, parental education, residential location, and school type on reading comprehension skills. Utilizing machine learning techniques, our analysis reveals a nuanced connection between autonomy, technological proficiency, and academic performance. Notably, family oversight of technology use emerges as a crucial factor in managing the impact of digital technology and the Internet on reading comprehension skills. The study emphasizes the necessity for a balanced and supervised introduction to technology from an early age. Contrary to current trends, our findings indicate that online gaming may not contribute positively to reading comprehension skills, while moderate daily Internet use (1-4 h) proves beneficial. Furthermore, the study underscores the ongoing nature of acquiring reading comprehension and technological skills, emphasizing the need for continuous attention and guidance from childhood. Parental education levels are identified as partial predictors of children's performance, emphasizing the importance of a holistic educational approach that considers autonomy and technological literacy. This study advocates for addressing socio-economic and gender inequalities in education and highlights the crucial role of cooperation between schools and families, particularly those with lower educational levels.

ABSTRACT

This study examines learners' perceptions of the linguistic and learning potential of an AI-based English language learning app called Papua. The study took a quasi-experimental approach in which 128 students of the degree in Primary Education at the University of Huelva, Spain, gained experience of using the app over a six-week period, and then answered a questionnaire. This was of a quantitative design, and included the following components: attitudes towards learning English; attitudes towards learning oral and written skills, and towards opportunities for interacting in English; and attitudes towards the motivation provided by the app. These attitudes were contrasted according to the variables memory and self-evaluation. The results of the study showed that oral skills were perceived as the most improved skill. Participants also foregrounded the enhancement of memorization of vocabulary, and positively evaluated the self-evaluation feature included in the app.

ABSTRACT

Inadequate venous drainage decreases the efficiency of extracorporeal membrane oxygenation (ECMO). Pump augmentation may even make it worse due to collapse of the venous system under negative pressures. Furthermore, recirculation is a phenomenon that occurs when oxygenated blood supplied through the infusion cannula is withdrawn directly through the drainage cannula without contributing to the oxygenation of the patient and also compromises the efficacy of the therapy. Large drainage cannulas allow for similar flow rates at lower pump speed. But percutaneous insertion of these larger cannulas could be challenging. When using a self-expandable cannula, the diameter of the cannula for the insertion can be reduced, and once inserted, its intravascular diameter maximized, resulting in a large venous cannula due to in situ expansion after mandrel removal (up to 36F). We present a retrospective series of selfexpanding venous cannula 430 or 530 mm in length in six consecutive patients undergoing venovenous (VV) ECMO. No vascular or cardiac iatrogenic injury was caused during implantation. Target flows were reached, and no clinically significant recirculation was described in any case. The use of selfexpanding drainage cannulas was safe, and efficient drainage was achieved with easy and definitive unique positioning during cannulation.

ABSTRACT

OBJECTIVES: Frailty syndrome predicts adverse outcomes after surgical aortic valve replacement. However, disability or comorbidity is frequently associated with preoperative frailty evaluation. The effects of these domains on early and late outcomes were analysed. METHODS: A prospective study including patients aged ≥75 years with symptomatic severe aortic stenosis who received aortic valve replacement with or without coronary artery bypass grafting was conducted. We used the Cardiovascular Health Study Frailty Phenotype to assess frailty, the Lawton-Brody index to define disability and the Charlson comorbidity index (CCI) to evaluate comorbidity. RESULTS: Frailty was identified in 57 (31%), dependence in 18 (9.9%) and advanced comorbidity (CCI ≥ 4) in 67 (36.6%) of the 183 enrolled patients. Operative mortality (1.6%), transfusion rate and duration of stay increased in patients with CCI ≥4 (P < 0.005). There was a non-significant trend for these adverse outcomes among the frail patients. Follow-up was achieved in all patients (median/interquartile range 869/699-1099 days). Kaplan-Meier univariable analysis showed a reduced survival rate for frail and dependent patients and for those with multiple comorbidities (P < 0.05). According to multivariable analysis, frailty and comorbidity were independent risk factors for 1-year mortality, while disability and comorbidity, but not frailty, were risk factors for 3-year mortality (P < 0.05). CONCLUSIONS: Surgical aortic valve replacement in patients aged ≥75 years is a safe procedure with low mortality rates. Operative outcomes are mainly affected by comorbidities. The main influence of survival occurs throughout the first year, and an improved functional status prevents any progression towards disabilities, which could potentially benefit long-term outcomes.

ABSTRACT

Natural history of acute Stanford type A aortic dissection (AAAD) implies the need of emergent surgical treatment in the vast majority of cases. Nevertheless, conservative treatment has been described to yield acceptable outcomes, when compared to surgery, in selected high risk cases of thrombosed false lumen. We report a significant quick remodelling of the false lumen occurred in an 85-year-old female 6 days after conservative treatment.
