Efectes d’un entrenament planificat i controlat en minibàsquet (11 i 12 anys) sobre la potència anaeròbica

L’objectiu d’aquest treball ha estat avaluar els efectes que té, en nens, la participació en el programa d’entrenament esportiu dissenyat i controlat en minibàsquet, mitjançant l’índex de Korcek (GE, N = 12), sobre la potència anaeròbica en comparació amb un grup d’entrenament no planificat (GC, N = 12). El control del programa es va realitzar registrant la freqüència cardíaca mitjançant Sport Tester en les sessions d’entrenament i ajustant-ne la càrrega, segons l’índex de Korcek, als microcicles establerts en la planificació anual. El programa d’entrenament es va realitzar al llarg de set mesos, amb recollides de dades en dos moments diferents (primer mes i setè mes). La valoració de la potència anaeròbica es va estimar mitjançant la realització del test de Wingate en cicloergòmetre. Es van controlar les variables d’edat cronològica i biològica, pes, alçària, dos perímetres musculars, dos diàmetres ossis i tres plecs cutanis, i totes les variables van ser valorades seguint les normes establertes per l’“IWGK” i “GREC”. Els resultats mostren millores de la potència anaeròbica en el GE. Els components del GE presenten millores significatives en la resistència anaeròbica respecte del GC, i milloren de manera substancial l’índex de fatiga

ANÁLISIS COMPARATIVO POR SEXO Y DEPORTES DE LAS PRUEBAS FÍSICAS REALIZADAS EN EL PROGRAMA DE DETECCIÓN DE TALENTOS EN MELILLA 2002

El estudio del análisis comparativo efectuado a una población de deportistas seleccionados por las propias Federaciones Provinciales para participar en el “Programa de Detección de Talentos 2002” en la Ciudad Autónoma de Melilla” nos ha permitido establecer algunas conclusiones aludiendo a la comparación por sexo y por especialidad deportiva. En dicho programa han participado un total de 52 deportistas (Natación = 11; Atletismo = 6; Vela = 5; Gimnasia = 10; Pesca = 7; Golf = 3 y Tenis = 10) de los que 27 fueron varones y 25 mujeres. La descripción de la evaluación nos permitió establecer tres áreas de actuación: área médica; área física y área fisiológica. Dentro del área física fueron evaluados los siguientes parámetros: fuerza explosiva (Squat Jump, Counter movement y Abalakov), Fuerza resistencia (Saltos reactivos en 15”); velocidad coordinación (test de agilidad de 5 x 10 m); Resistencia cardiorrespiratoria (potencia aeróbica máxima a través de la carrera progresiva, con medida indirecta del consumo de O2); fuerza explosiva tren superior (lanzamiento del balón medicinal); flexibilidad (flexión del tronco desde la posición de sentado) y velocidad (50:30 m).Para ello hemos efectuado a través del paquete estadístico SPSS 10.0 un análisis de comparación de medias (t de student) para muestras independientes. Igualmente presentamos gráficas comparando las medias de los resultados descriptivos en algunas de las pruebas físicas realizadas. Entre las conclusiones destacar que existe diferencia significativa entre otras: en la prueba de flexibilidad (p = ,002); en el nº de saltos en la prueba de saltos reactivos (p = ,023); lanzamiento del balón medicinal (p = ,041) y presenta tendencia a la significación en la prueba de velocidad-coordinación (p = ,081) y en la sincronización de fibras (p = ,090). En el resto de pruebas no existen diferencias significativas. También se efectuó un análisis correlacional atendiendo a las variables peso, talla y edad por sexo.The study of the comparative analysis made a population of sportsmen selected by the own Provincial Federations to participate in the “Program of Detection of Talents 2002” in the Autonomous City of Melilla” it has allowed us to establish some conclusions mentioning to the comparison for sex and for sport speciality. In this program they have participated a total of 52 sportsmen (Swimming = 11; Athletics = 6; It veils = 5; Gymnastics = 10; He/she fishes = 7; Golf = 3 and Tennis = 10) of those that 27 were male and 25 women. The description of the evaluation allowed to settle down three performance areas: medical area; physical area and physiologic area. Inside the physical area the following parameters were evaluated: it forces plosive (Squat Jump, Counter movement and Abalakov), it Forces resistance (Jumps reagents in 15"); speed coordination (test of agility of 5 x 10 m); Resistance (power maximum aerobic through the progressive career, with measure insinuation of the consumption of O2); it forces explosive superior train (launching of the medicinal ball); flexibility (flexion of the trunk from the position of having sat down) and speed (50:30 m). For we have made it through the statistical package SPSS 10.0 an analysis of comparison of stockings (student t) for independent samples. Equally we present graphs comparing the stockings of the descriptive results in some the carried out physical tests. Among the conclusions to highlight that significant difference exists among others: in the test of flexibility (p = ,002); in the nº of jumps in the test of jumps reagents (p = ,023); launching of the medicinal ball (p = ,041) and it presents tendency to the significance in the test of speed - coordination (p = ,081) and in the synchronisation of fibers (p = ,090). In the rest of tests significant differences don’t exist. An analysis correlational was also made assisting to the variables weight, it carves and age for sex

Broad-band high-resolution rotational spectroscopy for laboratory astrophysics

We present a new experimental set-up devoted to the study of gas phase molecules and processes using broad-band high spectral resolution rotational spectroscopy. A reactor chamber is equipped with radio receivers similar to those used by radio astronomers to search for molecular emission in space. The whole range of the Q (31.5-50 GHz) and W bands (72-116.5 GHz) is available for rotational spectroscopy observations. The receivers are equipped with 16 × 2.5 GHz fast Fourier transform spectrometers with a spectral resolution of 38.14 kHz allowing the simultaneous observation of the complete Q band and one-third of the W band. The whole W band can be observed in three settings in which the Q band is always observed. Species such as CH3CN, OCS, and SO2 are detected, together with many of their isotopologues and vibrationally excited states, in very short observing times. The system permits automatic overnight observations, and integration times as long as 2.4 × 105 s have been reached. The chamber is equipped with a radiofrequency source to produce cold plasmas, and with four ultraviolet lamps to study photochemical processes. Plasmas of CH4, N2, CH3CN, NH3, O2, and H2, among other species, have been generated and the molecular products easily identified by the rotational spectrum, and via mass spectrometry and optical spectroscopy. Finally, the rotational spectrum of the lowest energy conformer of CH3CH2NHCHO (N-ethylformamide), a molecule previously characterized in microwave rotational spectroscopy, has been measured up to 116.5 GHz, allowing the accurate determination of its rotational and distortion constants and its search in space.We thank the European Research Council for funding support under Synergy Grant ERC-2013-SyG, G.A. 610256 (NANOCOSMOS).

Association between Use of Enhanced Recovery after Surgery Protocol and Postoperative Complications in Total Hip and Knee Arthroplasty in the Postoperative Outcomes Within Enhanced Recovery after Surgery Protocol in Elective Total Hip and Knee Arthroplasty Study (POWER2)

Importance: The Enhanced Recovery After Surgery (ERAS) care protocol has been shown to improve outcomes compared with traditional care in certain types of surgery. Objective: To assess the association of use of the ERAS protocols with complications in patients undergoing elective total hip arthroplasty (THA) and total knee arthroplasty (TKA). Design, Setting, and Participants: This multicenter, prospective cohort study included patients recruited from 131 centers in Spain from October 22 through December 22, 2018. All consecutive adults scheduled for elective THA or TKA were eligible for inclusion. Patients were stratified between those treated in a self-designated ERAS center (ERAS group) and those treated in a non-ERAS center (non-ERAS group). Data were analyzed from June 15 through September 15, 2019. Exposures: Total hip or knee arthroplasty and perioperative management. Sixteen individual ERAS items were assessed in all included patients, whether they were treated at a center that was part of an established ERAS protocol or not. Main Outcomes and Measures: The primary outcome was postoperative complications within 30 days after surgery. Secondary outcomes included length of stay and mortality. Results: During the 2-month recruitment period, 6146 patients were included (3580 women [58.2%]; median age, 71 [interquartile range (IQR), 63-76] years). Of these, 680 patients (11.1%) presented with postoperative complications. No differences were found in the number of patients with overall postoperative complications between ERAS and non-ERAS groups (163 [10.2%] vs 517 [11.4%]; odds ratio [OR], 0.89; 95% CI, 0.74-1.07; P =.22). Fewer patients in the ERAS group had moderate to severe complications (73 [4.6%] vs 279 [6.1%]; OR, 0.74; 95% CI, 0.56-0.96; P =.02). The median overall adherence rate with the ERAS protocol was 50.0% (IQR, 43.8%-62.5%), with the rate for ERAS facilities being 68.8% (IQR, 56.2%-81.2%) vs 50.0% (IQR, 37.5%-56.2%) at non-ERAS centers (P <.001). Among the patients with the highest and lowest quartiles of adherence to ERAS components, the patients with the highest adherence had fewer overall postoperative complications (144 [10.6%] vs 270 [13.0%]; OR, 0.80; 95% CI, 0.64-0.99; P <.001) and moderate to severe postoperative complications (59 [4.4%] vs 143 [6.9%]; OR, 0.62; 95% CI, 0.45-0.84; P <.001) and shorter median length of hospital stay (4 [IQR, 3-5] vs 5 [IQR, 4-6] days; OR, 0.97; 95% CI, 0.96-0.99; P <.001). Conclusions and Relevance: An increase in adherence to the ERAS program was associated with a decrease in postoperative complications, although only a few ERAS items were individually associated with improved outcomes

Incidence, clinical characteristics and management of inflammatory bowel disease in Spain: large-scale epidemiological study

(1) Aims: To assess the incidence of inflammatory bowel disease (IBD) in Spain, to describe the main epidemiological and clinical characteristics at diagnosis and the evolution of the disease, and to explore the use of drug treatments. (2) Methods: Prospective, population-based nationwide registry. Adult patients diagnosed with IBD—Crohn’s disease (CD), ulcerative colitis (UC) or IBD unclassified (IBD-U)—during 2017 in Spain were included and were followed-up for 1 year. (3) Results: We identified 3611 incident cases of IBD diagnosed during 2017 in 108 hospitals covering over 22 million inhabitants. The overall incidence (cases/100, 000 person-years) was 16 for IBD, 7.5 for CD, 8 for UC, and 0.5 for IBD-U; 53% of patients were male and median age was 43 years (interquartile range = 31–56 years). During a median 12-month follow-up, 34% of patients were treated with systemic steroids, 25% with immunomodulators, 15% with biologics and 5.6% underwent surgery. The percentage of patients under these treatments was significantly higher in CD than UC and IBD-U. Use of systemic steroids and biologics was significantly higher in hospitals with high resources. In total, 28% of patients were hospitalized (35% CD and 22% UC patients, p < 0.01). (4) Conclusion: The incidence of IBD in Spain is rather high and similar to that reported in Northern Europe. IBD patients require substantial therapeutic resources, which are greater in CD and in hospitals with high resources, and much higher than previously reported. One third of patients are hospitalized in the first year after diagnosis and a relevant proportion undergo surgery. © 2021 by the authors. Licensee MDPI, Basel, Switzerland
