Background: Novel player tracking technologies can change the understanding of performance determinants in team sports by allowing to accurately measuring the activity demands. The aim of this study was to identify how the defensive pressure affects the time-motion variables and the technical actions in ***: Twenty international male players(age: 16.05 ± 2.09 years, weight: 73.13 ± 8.10 kg, height: 183.10 ± 5.88 cm) played two 10 min basketball quarters, where they used a man-to-man 1/4-court defense until the 4th min(F1/4), changed to man-to-man full court(FULL) for 3 min and, from the 7th to the 10 th min returned to 1/4-court defense(S1/4). A computerized notational analysis was performed using Simi Scout and positional data were captured with the Ubisense Real Time Location System(mean sampling rate 3.74 ± 0.45 Hz per transmitter/player).Results: The time-motion variables presented similar results between defensive conditions, showing a total distance covered around 90 m/***, results suggested possible vertical jump impairments in S1/4 periods. There was more distance covered while jogging in the offensive court(38.15 ± 12.17 m/min offensive court vs. 32.94 ± 10.84 m/min defensive court, p < 0.05) and more distance covered while running in the defensive court(16.41 ± 10.27 m/min offensive court vs. 19.56 ± 10.29 m/min defensive court, p < 0.05).Conclusion: These results suggest how to improve task representativeness during specific conditioning or game-based training situations and also to help coaches' strategic decisions during the games.

The object of this study is to assess the Ivlg （intravenous immunoglobulin） use in inflammatory systemic and immune-mediated illnesses, in patients older than 18 years in a tertiary hospital. The assessment also intends to ensure if the clinical indications matched with the evidence-based clinical guidelines recommendations of use. Analytical, observational, transversal and retrospective study carried out during 2012. Patients with inflammatory systemic and immuno-mediated illnesses, older than 18 years old, were included. The data collected were： age, sex, number of administrations, dosage, frequency, commercial brand and the indication for what the Ivlg treatment has been prescribed. As a reference guide the British Health Department Clinical Guidelines for Immunoglobulin Use （2nd edition, 2008, and 2nd edition update 2011） and its Spanish adaption were used. The lvlg treatment was justified by a grade of recommendation A, B or C in 41% of the indications. Thus in 59% （grey indications or unclear diagnosis） the IvIg use would be questionable because of its weak evidence. It was found one indication for what the prescription of IvIg was clearly not recommended. The inflammatory systemic and immune-mediated diseases include many pathologies for what the IvIg use has not been properly studied. There is a need of consensus guidelines for IvIg use to guide doctors and pharmacists in their clinical practice. Moreover, it is important to prioritize which indications and circumstances are of first importance to have their supply guaranteed.

AIM: To describe our experience concerning the surgical treatment of Strasberg E-4(Bismuth Ⅳ) bile duct injuries. METHODS: In an 18-year period, among 603 patients referred to our hospital for surgical treatment of complex bile duct injuries, 53 presented involvement of the hilar confluence classified as Strasberg E4 injuries. Imagenological studies, mainly magnetic resonance imaging showed a loss of confluence. The files of these patients were analyzed and general data were recorded, including type of operation and postoperative outcome with emphasis on postoperative cholangitis, liver function test and quality of life. The mean time of follow-up was of 55.9 ± 52.9 mo(median = 38.5, minimum = 2, maximum = 181.2). All other patients with Strasberg A, B, C, D, E1, E2, E3, or E5 biliary injuries were excluded from this ***: Patients were divided in three groups: G1(n = 21): Construction of neoconfluence + Roux-en-Y hepatojejunostomy. G2(n = 26): Roux-en-Y portoenterostomy. G3(n = 6): Double(right and left) Rouxen-Y hepatojejunostomy. Cholangitis was recorded in two patients in group 1, in 14 patients in group 2, and in one patient in group 3. All of them required transhepatic instrumentation of the anastomosis and six patients needed live ***: Loss of confluence represents a surgicalchallenge. There are several treatment options at different stages. Roux-en-Y bilioenteric anastomosis(neoconfluence, double-barrel anastomosis, portoenterostomy) is the treatment of choice, and when it is technically possible, building of a neoconfluence has better outcomes. When liver cirrhosis is shown, liver transplantation is the best choice.

BACKGROUND: Low-frequency and high-risk situations, such as neonatal resuscitation, are the ideal targets for simulation-based learning. The aim of this paper is to present the structure of our internal neonatal resuscitation training program, using a realistic, simulated delivery room, and to present the participants' opinions about teamwork, emotional stress, and their subjective ability to face a resuscitation. METHODS: We administered a training course to 24 doctors and midwives. One of the simulation classrooms was modified to appear similar to a real delivery room. Four scenarios were conducted using a previously designed checklist of primary and secondary goals. Upon completion, all students participated in a debriefing session with the help of a video review. RESULTS: Students rated the achievement of their previously defined goals on a scale of 1 to 5. Grouping together the percentages of the highest ratings (Categories 4 and 5), 83.4% (20/24) of the students considered the course useful for acquiring clinical skills. For 87.5% (21/24) of the students, the scenarios simulated real clinical situations, the room properly simulated a real delivery room, and the course improved the students' ability to work in a team. For 66.6% (16/24) of the students, the course improved their stress in confronting neonatal resuscitation. Initially, only 33.3% (8/24) of the students considered themselves very capable or fully able to cope with a resuscitation. After the course, that percentage rose to 62.5% (15/24). CONCLUSIONS: The incorporation of simulation-based learning into neonatal resuscitation teaching programs, using realistic scenarios, is useful and offers the possibility of acquiring technical skills, but it also allows for the improvement of teamwork and the adoption of different roles and positive attitudes towards emotional stress.

The collective response of electrons in an ultrathin foil target irradiated by an ultraintense(~6×10^(20)W cm^(-2)) laser pulse is investigated experimentally and via 3D particle-in-cell simulations. It is shown that if the target is sufficiently thin that the laser induces significant radiation pressure, but not thin enough to become relativistically transparent to the laser light, the resulting relativistic electron beam is elliptical, with the major axis of the ellipse directed along the laser polarization axis. When the target thickness is decreased such that it becomes relativistically transparent early in the interaction with the laser pulse, diffraction of the transmitted laser light occurs through a so called ‘relativistic plasma aperture', inducing structure in the spatial-intensity profile of the beam of energetic electrons. It is shown that the electron beam profile can be modified by variation of the target thickness and degree of ellipticity in the laser polarization.

The objective of this study was to estimate genetic parameters and quantify the correlations between late blight (LB) resistance and fruit quality traits in 220 families F2:3, under tropical field conditions. The families were arranged in randomized blocks in field trials, with six resistant inbred lines used as control, in plots of five plants. It evaluated the severity in the middle of the epidemy, final severity, area under the curve of progress of late blight, pH, total soluble solids, titratable acidity and flavor. There is genetic variability for epidemiological variables and total soluble solids. Heritabilities, obtained by parent-offspring regression, were high and indicated the possibility of satisfactory genetics gains and success in the introgression of resistance alleles. The correlations were negative, of high to intermediate magnitude, among the variables area under the curve of progress of late blight, total soluble solids and total titratable acidity.

Toxicity of wastewater treatment plant (WWTP) effluents is usually assessed with standardized bioassays, as e.g. the Fish Embryo Toxicity test (FET), but assessment of sub-lethal toxic effects requires to develop more adapted tests. The present work aimed to add the recording of several sub-lethal endpoints in exposed zebrafish embryo-larval stages in order to increase the sensitivity of residual toxicity evaluation of WWTP effluents using a semi-quantitative method (iFET score). This approach was complemented with the genotoxicity assessment on the exposed embryos, a sub-acute hazard particularly relevant to evaluate a potential chronic toxicity risk of low and multi-contaminated environmental matrices. Additionally, endocrine activities of effluents were quantified using human reporter cell lines. This test battery was applied to the assessment of the residual toxicity of five biological treatment effluents, further treated or not using various ozonation treatments intended to improve pharmaceutical compounds removal. Acute toxicity towards zebrafish embryos was very low. However, iFET score approach proposed was able to reveal residual toxicity through the presence of developmental abnormalities in all samples tested. Additionally, a low residual genotoxicity was measured in embryos exposed to two of the WWTP effluents when all excepted one exhibited a residual endocrine activity potential in the ng/L range providing complementary information on the occurrence of endocrine active chemicals and their reduction by different processes. To sum up, such a simplified and ecologically relevant test battery was found sensitive enough to characterize and differentiate various residual effluent’s ecotoxicity at contaminant levels of environmental concern.
