Analysis of the traditional methods of education and learning of the collective sports in the primary education and innovative didactic proposals

[Resumen] La metodología empleada en la enseñanza de los deportes colectivos en los centros educativos está desactualizada. El profesorado implicado no valora la evolución que este ámbito sufrió en las últimas décadas y sigue echando mano de los procesos educativos más tradicionales provocando grandes fracasos en el aprendizaje de dichos deportes. Este trabajo realiza una profunda revisión bibliográfica y elabora una unidad didáctica para un aula de sexto de educación primaria. Esta intervención educativa se basa en las técnicas de enseñanza y aprendizaje de los modelos comprensivos, cognitivos, integrados y constructivistas[Abstract] The methodology employed in the education of the collective sports in the educational centres is not updated.

Contact detection between a small ellipsoid and another quadric

[Abstract] We analyze the characteristic polynomial associated to an ellipsoid and another quadric in the context of the contact detection problem. We obtain a necessary and sufficient condition for an efficient method to detect contact. This condition, named smallness condition, is a feature on the size and the shape of the quadrics and can be checked directly from their parameters. Under this hypothesis, contact can be noticed by means of the expressions in a discriminant system of the characteristic polynomial. Furthermore, relative positions can be classified through the sign of the coefficients of this polynomial. As an application of these results, a method to detect contact between a small ellipsoid and a combination of quadrics is given

Dietary Consumption of Polyphenols in University Students Relationship with Their Health-Related Habits

Polyphenols are compounds derived from plants found in foods with potential health benefits due to their antioxidant properties. The aim of this study was to establish the consumption of polyphenols in university students and the relationship between the amount of polyphenols consumed and their health-related habits. For this, 270 university students answered a validated food consumption frequency questionnaire (FFQ), a physical activity questionnaire (IPAQ), and a health and lifestyle questionnaire. From the FFQ, the daily consumption of classes and subclasses of polyphenols was calculated. Then, the population was classified in terciles according to the polyphenol consumption, and the physical activity, smoking habits, and the prevalence of allergy and obesity in each tercile was established. The consumption of polyphenols was about 1.5 g/day, being flavonoids and phenolic acids the most consumed. The main sources of polyphenol consumption were cocoa, coffee, and to a lesser extent, fruits. There were no significant differences in consumption according to sex, BMI, health status, or physical activity. The smoking habit was related to a high consumption of polyphenols, mainly those that came from coffee and cocoa. Students who smoke had a higher consumption of polyphenols with respect to nonsmokers, especially those derived from coffee

Studies of the Microbiological and Physico-Chemical Composition of Goat ́s Milk from North-Western Spain

P. 39-44Twenty-seven samples of raw goat’s milk were collected from four farms in the North-West of Spain with the aim of analysing counts of various mesophilic bacteria and of determining the physical and chemical composition during different seasons of the year. Overall mean values for mesophilic aerobic micro-organisms (Standard Plate Counts, SPCs) were above 5.6 log cfu/ml, very similar to the counts on M17 agar (presumptive Lactococcus, 5.6 log cfu/ml) and higher than the counts on MSE agar (presumptive Leuconostoc, 4.6 log cfu/ml) and on MRS agar (presumptive Lactobacillus, 4.4 log cfu/ml). Counts were generally higher in winter than in spring and summer, although no statistically significant differences were found. The microbiological quality of raw goat’s milk produced in the farms investigated in the North-West of Spain is only partially in accordance with European Union standards. Hence, hygiene practices should be improved so as to decrease the standard plate counts on some of the farms checked. The physical and chemical composition tests also showed higher values for fat, protein and dry extract during the winter season. The average fat content (5.5 g/100 ml) and dry extract (14.7 g/100 ml) were higher than the values noted in other studies, making this of interest for cheese makingS

Relationship between Cocoa Intake and Healthy Status: A Pilot Study in University Students

Due to its polyphenol content, cocoa's potential health effects are attracting much attention, showing, among other things, cardioprotective, anti-inflammatory, anti-obesity, and neuroprotective actions. However, there is very limited information regarding the effect of cocoa on human immunity. This study aimed to establish the relationship between cocoa consumption and health status, focusing on physical activity habits and allergy prevalence in young people. For this, a sample of 270 university students was recruited to complete a food frequency questionnaire, the International Physical Activity Questionnaire (IPAQ), and a lifestyle and health status questionnaire. The results were analysed by classifying the participants into tertiles defined according to their cocoa consumption: low (LC), moderate (MC), and high (HC) consumers. The consumption of cocoa inversely correlated with physical activity and the MC group had significantly less chronic disease frequency than the LC group. The percentage of allergic people in the MC and HC groups was lower than that in the LC group and, moreover, the cocoa intake, especially moderate consumption, was also associated with a lower presence of allergic symptoms. Thus, from these results a positive effect of cocoa intake on allergy can be suggested in the young population.

Incidence of COVID-19 in Children and Young People Who Play Federated Football

[Abstract] Aim: To determine the incidence of SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) infection in children and young people who play federated football. Methods: Prospective study, from October 2020 to January 2021, in players aged 4 to 19 years from federated football clubs in Galicia, Spain (N = 23,845). Outbreaks and cases of SARS-CoV-2 infection were recorded. The cumulative incidence was compared with the incidence registered in Galicia in the same age range. Results: The cumulative incidence was 29.8 cases per 10,000 licenses in 4 months, lower than the incidence registered in the general population for all ages and both sexes (283.7 per 10,000 inhabitants; rate ratio = 9.5). It was higher in January (40.7 per 10,000), coinciding with the population peak. More cases were registered in futsal (42.9 vs 27.5 per 10,000) and competitions with periodic screenings (127.4 vs 9.1 per 10,000). There were 2 outbreaks in 2389 teams (0.08%). Conclusion: The results support the safety of football practice in children and young people with prevention protocols

Behaviour of Non-O157 STEC and Atypical EPEC during the Manufacturing and Ripening of Raw Milk Cheese

12 p.This study was carried out to assess the survival of Shiga toxin-producing E. coli (STEC) and atypical enteropathogenic Escherichia coli (aEPEC) during the traditional manufacturing and ripening of Spanish hard cheese from raw cow’s milk. Milk samples were spiked with up to 3.1–3.5 log cfu/mL of one strain of STEC (O140:H32 serotype) and one of aEPEC (serotype O25:H2). The first steps of cheesemaking allow for a STEC and aEPEC increase of more than 1 log cfu/mL (up to 4.74 log cfu/g and 4.55 log cfu/g, respectively). After cheese pressing, a steady reduction of both populations was observed, with the STEC strain being more sensitive. The studied pathogenic E. coli populations decreased by 1.32 log cfu/g in STEC and 0.59 log cfu/g in aEPEC in cheese ripened during a minimum period of 60 d. Therefore, a moderate contamination by these diarrhoeagenic E. coli pathotypes, in particular, with aEPEC, on cheese manufactured from raw milk may not be totally controlled through the cheesemaking process and during a maturation of 90 d. These findings remark the importance of improvement in bacteriological quality of raw milk and crosscontamination prevention with diarrhoeagenic E. coli in the dairy industryS

Nosocomial Infection Outbreak due to SARS-COV-2 in a Hospital Unit of Particularly Vulnerable Patients

[Abstract] Objectives: To report a COVID-19 outbreak among workers and inpatients at a medical ward for especially vulnerable patients. Methods: Descriptive study of a nosocomial COVID-19 outbreak registered in March-April 2020 at medical ward of onco-hematological patients in an Spanish hospital. Confirmed cases were hospitalized patients, healthcare and non-healthcare workers who tested positive by PCR on a nasopharyngeal swab. Results: Twenty-two COVID-19 cases (12 workers and 10 inpatients) were laboratory-confirmed. Initial cases were a healthcare provider and a visitor who tested positive. The median patients age was 73 years (range 62-88). The main reason of admission was haematological in 8 patients and oncologic in 2. All patients followed an immunosuppressive treatment, 5/10 with high-flow oxygen nebulizations. Five patients presented a moderate/serious evolution, and 5 patients died. The mean workers age was 42.1±10.9. One healthworker required Intensive Care Unit admission, and all of them recovered completely. Conclusions: In the hospital setting, close patients surveillance for SARS-CoV-2 is essential, especially in immunosuppressed patients. Replacing nebulizations or high-flow oxygen therapies, when other equivalent options were available, to reduce dispersion, and controlling ventilation ducts, together with hygiene measures and an active follow-up on inpatients, visitors and workers appear to be important in preventing nosocomial outbreaks

Predictive Model and Mortality Risk Score during Admission for Ischaemic Stroke with Conservative Treatment

This work was supported by the "Fundacion Progreso y Salud", in the context of FPS 2020-R&I projects in Primary Care, Regional hospitals and CHARES. Grant number AP-0013-2020-C1-F1 and the APC was funded by the same.Background: Stroke is the second cause of mortality worldwide and the first in women. The aim of this study is to develop a predictive model to estimate the risk of mortality in the admission of patients who have not received reperfusion treatment. Methods: A retrospective cohort study was conducted of a clinical–administrative database, reflecting all cases of non-reperfused ischaemic stroke admitted to Spanish hospitals during the period 2008–2012. A predictive model based on logistic regression was developed on a training cohort and later validated by the “hold-out” method. Complementary machine learning techniques were also explored. Results: The resulting model had the following nine variables, all readily obtainable during initial care. Age (OR 1.069), female sex (OR 1.202), readmission (OR 2.008), hypertension (OR 0.726), diabetes (OR 1.105), atrial fibrillation (OR 1.537), dyslipidaemia (0.638), heart failure (OR 1.518) and neurological symptoms suggestive of posterior fossa involvement (OR 2.639). The predictability was moderate (AUC 0.742, 95% CI: 0.737–0.747), with good visual calibration; Pearson’s chi-square test revealed non-significant calibration. An easily consulted risk score was prepared. Conclusions: It is possible to create a predictive model of mortality for patients with ischaemic stroke from which important advances can be made towards optimising the quality and efficiency of care. The model results are available within a few minutes of admission and would provide a valuable complementary resource for the neurologist.Fundacion Progreso y Salud AP-0013-2020-C1-F

A new Food Frequency Questionnaire to assess chocolate and cocoa consumption

Objective Cocoa has been highlighted as a food with potential benefits to human health because of its polyphenol content. However, few studies show the contribution of cocoa and chocolate products in polyphenol intake. The aim of this work was to develop a food frequency questionnaire (FFQ) for evaluating the intake of food products containing cocoa (C-FFQ). Methods A sample of 50 university students was recruited to complete the 90-item questionnaire, a validated questionnaire (called here European Food Safety Authority [EFSA]-Q) as well as a 24-hour dietary recall (24 HDR). Spearman correlation test, Bland-Altman plots, and quintile classification analysis were conducted together with the Wilcoxon test and descriptive statistics. Results Significant correlations between the C-FFQ and the EFSA-Q for the most common cocoa/chocolate products were observed (P < 0.05), as well as between data from the C-FFQ and 24 HDR (P < 0.05). However, a number of cocoa/chocolate products frequently consumed by the participants were detected by the C-FFQ and 24 HDR which were not included in the EFSA-Q. According to the C-FFQ, chocolate bars were the main source of cocoa in university students, but dairy products also provided an important amount of cocoa. Conclusion The developed C-FFQ questionnaire can be considered as a valid option for assessing the consumption frequency of cocoa/chocolate-derived products, thereby allowing the evaluation of cocoa polyphenol intake in further studies
