How Health Habits Influence the Physiological Response During a Physical Activity in Extreme Temperatures?
(MDPI, 2020) Martín-Rodríguez , Francisco; Castro-Villamor , Miguel Ángel; Martín Conty, José Luis; Criado Álvarez, Juan José; Castillo Sarmiento, Carlos Alberto; Maestre Miquel, Clara; Mohedano Moriano, Alicia; Polonio López, Begoña; Durántez Fernández, Carlos; Viñuela Sánchez, Antonio
Background: The purpose of the study was to determine to what degree the health habits of university students influence their physiological response during a 10-min high-intensity exercise. Methods: We conducted a cross-sectional cohort study with 59 health science students, in which we analyzed their adherence to a Mediterranean and low-fat diet, as well as their activity levels. We correlated these factors with the physiological response (lactic acid and heart rate) and a series of anthropometric parameters in intense physical activity (cardiopulmonary resuscitation (CPR) for 10 min) in three scenarios: extreme cold, extreme heat and a control situation at room temperature. Results: The results of this study demonstrate that in university students, a greater adherence to the Mediterranean diet was associated with a better response to physical exercise, in this case, 10-min CPR, in hostile environments. Conclusions: Following healthy eating guidelines improves physical performance and delays the appearance of fatigue; both are important aspects for a better performance of CPR.

Kubernetes Scheduling: Taxonomy, Ongoing Issues and Challenges
(Association for Computing Machinery (ACM), 2022) Carrión Espinosa, María del Carmen
Continuous integration enables the development of microservices-based applications using container virtualization technology. Container orchestration systems such as Kubernetes, which has become the de facto standard, simplify the deployment of container-based applications. However, developing efficient and well-defined orchestration systems is a challenge. This article focuses specifically on the scheduler, a key orchestrator task that assigns physical resources to containers. Scheduling approaches are designed based on different Quality of Service (QoS) parameters to provide limited response time, efficient energy consumption, better resource utilization, and other things. This article aims to establish insight knowledge into Kubernetes scheduling, find the main gaps, and thus guide future research in the area. Therefore, we conduct a study of empirical research on Kubernetes scheduling techniques and present a new taxonomy for Kubernetes scheduling. The challenges, future direction, and research opportunities are also discussed.

Effects of the use of autobiographical photographs on emotional induction in older adults: a systematic review
(Springer, 2023) Toledano González, Abel; Romero Ayuso, Dulce Nombre de María; Fernández Pérez, Dolores; Nieto López, Marta; Ricarte Trives, Jorge Javier; Navarro Bravo, Beatriz; Ros Segura, Laura; Latorre Postigo, José Miguel
There is evidence to support the positive contribution of autobiographical recall based techniques on individuals’ quality of life, mood and cognitive functioning. In this review, we analyzed the effects of the use of personal photographs in interventions based on autobiographical memory in older people with and without cognitive impairment. The PRISMA guidelines for systematic reviews were followed. The search was carried out in the electronic databases Web of Sciences (WOS), Medline (PubMed), SCIELO and PsycInfo (American Psychological Association). The articles based on clinical trials selected were evaluated using the PEDRo scale, which is specific to this type of article. Of the 1098 articles initially found, 6 met the inclusion criteria. The final articles focused their intervention on the use of autobiographical photographs as a means of stimulation. The results show that the use of photographs in different autobiographical recall stimulation techniques is associated with higher scores on well-being and quality of life, as well as with improvements in personal identity and cognitive functioning. This suggests that using personal photographs shows promise in enhancing the effect of these types of interventions in healthy or cognitively impaired older adults.

How effective are films in inducing positive and negative emotional states? A meta-analysis.
(Public Library of Science, 2019) Fernández Aguilar, María de la Luz; Navarro Bravo, Beatriz; Ricarte Trives, Jorge Javier; Ros Segura, Laura; Latorre Postigo, José Miguel
Meta-analyses and reviews on emotion research have shown the use of film clips to be one of the most effective methods of mood induction. Nonetheless, the effectiveness of this method when positive, negative and neutral emotional targets are studied under similar experimental conditions is currently unknown. This comprehensive meta-analysis included only studies that implemented neutral, positive and negative mood inductions to evaluate the effectiveness of the film clip method as a mood induction procedure. In addition, several factors related to the films, sample and experimental procedure used, the number of emotional categories, for example, or the number of film clips watched, were included to study their influence on the effectiveness of this mood induction procedure. Forty-five studies were included with 6675 participants and 12 possible moderator variables according to the sample and the research procedure. Our findings suggest that film clips are especially powerful in inducing negative mood states (Hedges’ g for valence = -1.49 and for arousal = -1.77) although they are also effective inducers of positive mood states (Hedges’ g for valence of = . -1.22 and for arousal = -1.34). Additionally, this meta-analysis reveals that variables, such as the number of emotional categories or the type of stimulus used to measure the baseline, should be considered.

Lactate improves the predictive ability of the National Early Warning Score 2 in the emergency department
(Elsevier, 2021) Castro Villamor, Miguel Ángel; López Izquierdo, Raul; Fernández Méndez, Felipe; Jorge Soto, Cristina; Martín Rodriguez, Francisco; Durántez Fernández, Carlos; Martín Conty, José Luis; Polonio López, Begoña; Maestre Miquel, Clara; Viñuela Sánchez, Antonio; Mordillo Mateos, Laura
Aims: The aim of this study was to compare the ability to predict 2-, 7-, 14-, and 30-day in-hospital mortality of lactate vs the National Early Warning Score 2 (NEWS2) vs the arithmetic sum of the NEWS2 plus the numerical value of lactate (NEWS2-L). Methods: This was a prospective, multicentric, emergency department delivery, pragmatic cohort study. To determine the predictive capacity of lactate, we calculated the NEWS2 and NEWS2-L in adult patients (aged >18 years) transferred with high priority by ambulance to the emergency department in five hospitals of Castilla y Leon (Spain) between November 1, 2019, and September 30, 2020. The area under the receiver operating characteristic curve of each of the scales was calculated in terms of mortality for every time frame (2, 7, 14, and 30 days). We determined the cut-off point of each scale that offered highest sensitivity and specificity using the Youden index. Results: A total of 1716 participants were included, and the in-hospital mortality rates at 2, 7, 14, and 30 days were of 7.8% (134 cases), 11.6% (200 cases), 14.2% (243 cases), and 17.2% (295 cases), respectively. The best cut-off point determined in the NEWS2 was 6.5 points (sensitivity of 97% and specificity of 59%), and for lactate, the cut-off point was 3.3 mmol/L (sensitivity of 79% and specificity of 72%). Finally, the combined NEWS2-L showed a cut-off point of 11.7 (sensitivity of 86% and a specificity of 85%). The area under the receiver operating characteristic curve of the NEWS2, lactate, and NEWS2-L in the validation cohort for 2-day mortality was 0.889, 0.856, and 0.923, respectively (p<0.001 in all cases). Conclusions: The new score generated, NEWS2-L, obtained better statistical results than its components (NEWS2 and lactate) separately.
