    One of the fundamental problems facing teachers of physical education (PE) is how to increase pupils' motivation. From the point of view of goal achievement, guidelines need to be established so that information may be used to greater effect in classes. This study examined the relationship between the motivational climate created by the PE teacher and the intrinsic motivation of the preparatory sessions together with self-confidence and anxiety prior to competition and pre- and post-competition mood states. The sample was made up of school children (M age = 11.7) from a state school (N = 115), who, after an introduction to an athletics course of 12 sessions, took part in a sports competition. During this time, a teacher (trained to this effect) manipulated the motivational climate, adapting the strategies of TARGET (11, 12, 26, 28). The mastery climate was linked to enjoyment, perceived ability, and effort in the PE classes, as well as to pre-competition somatic anxiety and post-competition vigor. On the other hand, the performance climate was associated with self-confidence, pre-competition vigor, and post-competition stress. The results are discussed in relation to achievement goal theory and motivational climate manipulation

    OBJECTIVE: A task force of scientists at the International Congress on Antiphospholipid Antibodies recognized that phosphatidylserine-dependent antiprothrombin antibodies (aPS/PT) might contribute to a better identification of antiphospholipid syndrome (APS). Accordingly, initial and replication retrospective, cross-sectional multicentre studies were conducted to ascertain the value of aPS/PT for APS diagnosis. METHODS: In the initial study (eight centres, seven countries), clinical/laboratory data were retrospectively collected. Serum/plasma samples were tested for IgG aPS/PT at Inova Diagnostics (Inova) using two ELISA kits. A replication study (five centres, five countries) was carried out afterwards. RESULTS: In the initial study (n = 247), a moderate agreement between the IgG aPS/PT Inova and MBL ELISA kits was observed (k = 0.598). IgG aPS/PT were more prevalent in APS patients (51%) than in those without (9%), OR 10.8, 95% CI (4.0-29.3), p < 0.0001. Sensitivity, specificity, positive (LR+) and negative (LR-) likelihood ratio of IgG aPS/PT for APS diagnosis were 51%, 91%, 5.9 and 0.5, respectively. In the replication study (n = 214), a moderate/substantial agreement between the IgG aPS/PT results obtained with both ELISA kits was observed (k = 0.630). IgG aPS/PT were more prevalent in APS patients (47%) than in those without (12%), OR 6.4, 95% CI (2.6-16), p < 0.0001. Sensitivity, specificity, LR + and LR- for APS diagnosis were 47%, 88%, 3.9 and 0.6, respectively. CONCLUSIONS: IgG aPS/PT detection is an easily performed laboratory parameter that might contribute to a better and more complete identification of patients with APS.info:eu-repo/semantics/publishedVersio

The SIAQ is a 15 item questionnaire to assess five types of athlete imagery ability: skill imagery ability, strategy imagery ability, goal imagery ability, affect imagery abi- lity, and mastery imagery ability. The study consisted of a sample of 360 athletes, 93 women and 267 men, of different individual and team sports. Taking the final theoretical model of Williams and Cumming (2011), the researchers conducted a Confirmatory Factor Analysis (CFA) that revealed a model of 5 factors and 15 items with evidence of factorial validity. Fur- thermore, an analysis of internal consistency (Cronbach’s alpha, composite reliability and Average Variance Extracted) and a test-retest analysis were carried out, with a time interval of a month in between, to find evidence of the reliability of the instrument. In general, the CHID demonstrates good factorial validity and internal reliability.Resumo: Esta pesquisa teve como objetivo encontrar evidências de valida- de e confiabilidade do questionário Sport Imagery Ability Questionnaire SIAQ (Williams e Cumming, 2011) em uma versão traduzida em espan- hol chamada «Cuestionario de Habilidad de Imaginería en el Deporte» (CHID, Cuestionário de Habilidade de Imagiologia no Deporte).

    Postnatal steroids, often used to prevent and treat bronchopulmonary dysplasia, may influence the growth of preterm infants, although data are scarce in the literature. This is a multicenter cohort study including surviving preterm infants <32 weeks at birth (n = 17,621) from the Spanish Neonatal Network SEN1500 database, without major congenital malformations. Linear regression models were adjusted for postnatal steroids, respiratory severity course (invasive mechanical ventilation at 28 days), progression to moderate-severe bronchopulmonary dysplasia (O2 at 36 weeks), length of stay, sex, gestational age and z-scores at birth. A subgroup analysis depending on the timing of administration, ventilation status at 28 days and moderate-severe BPD diagnosis was also performed. Overall, systemic postnatal steroids were not independently associated with poorer weight gain (0.1; 95% CI: -0.05 to 0.2 g/kg/day), linear growth (0; 95% CI: -0.03 to 0.01 cm/week) or head circumference growth (-0.01; 95% CI: -0.02 to 0 cm/week). Patients who received steroids after 28 days or who were not O2 dependent at 36 weeks after having received steroids gained more weight (0.22; 95% CI: 0.04 to 0.4 and 0.2; 95% CI: 0.004 to 0.5 g/kg/day, respectively). Globally, systemic postnatal steroids had no significant adjusted effect on postnatal growth

    Exploring clinical, echocardiographic and molecular biomarkers to predict bronchopulmonary dysplasia

    INTRODUCTION: Bronchopulmonary dysplasia (BPD) is the most common chronic lung disease in childhood, related to prematurity, and the most common cause of pulmonary hypertension (PH) secondary to pulmonary disease in children. Moderate and severe BPD have a worse outcome and relate more frequently with PH. The prediction of moderate or severe BPD development in extremely premature newborns is vital to implement preventive strategies. Starting with the hypothesis that molecular biomarkers were better than clinical and echocardiographic factors, this study aims to explore the ability of clinical, echocardiographic and analytical variables to predict moderate or severe BPD in a cohort of extremely preterm infants. PATIENTS AND METHODS: We designed a prospective longitudinal study, in which we followed a cohort of preterm newborns (gestational age <28 weeks and weight </= 1250 grams). In these newborns we recorded weekly clinical and echocardiographic variables as well as blood and tracheal aspirate samples, to analyze molecular biomarkers (IL-6, IL-1, IP10, uric acid, HGF, endothelin-1, VEGF, CCL5). Variables and samples were collected since birth up to week 36 (postmenstrual age), time-point at which the diagnosis of BPD is established. RESULTS: We included 50 patients with a median gestational age of 26 weeks (IQR 25-27) and weight of 871 g (SD 161,0) (range 590-1200g). Three patients were excluded due to an early death. Thirty-five patients (74.5%) developed BPD (mild n = 14, moderate n = 15, severe n = 6). We performed a logistic regression in order to identify risk factors for moderate or severe BPD. We compared two predictive models, one with two variables (mechanical ventilation and inter-ventricular septum flattening), and another-one with an additional molecular biomarker (ET-1). CONCLUSIONS: The combination of clinical and echocardiographic variables is a valuable tool for determining the risk of BPD. We find the two variable model (mechanical ventilation and echocardiographic signs of PH) more practical for clinical and research purposes. Future research on BPD prediction should be oriented to explore the potential role of ET-1

    Restaging Feminisms

    Restaging Feminisms proposes a re-encounter with the three political (liberal, radical, and socialist) strands that were core to seventies feminism and to pioneering feminist analysis in theatre studies. I undertake this re-engagement not with a view to a nostalgic rehabilitation of the past, but rather to explore how the past folds into the present: to understand how, in the context of British theatre, re-presentations of liberal, radical, and socialist feminisms might connect the past to present political and critical practices
