The aim of this study was to evaluate the mid-term outcomes of the laparoscopic ileal interposition associated to a sleeve gastrectomy (LII-SG) for the treatment of morbid obesity. The procedure was performed in 120 patients: 71 women and 49 men with mean age of 41.4 years. Mean body mass index (BMI) was 43.4 +/- 4.2 kg/m(2). Patients had to meet requirements of the 1991 NIH conference criteria for bariatric operations. Associated comorbidities were observed in all patients, including dyslipidemia in 51.7%, hypertension in 35.8%, type 2 diabetes in 15.8%, degenerative joint disease in 55%, gastroesophageal reflux disease in 36.7%, sleep apnea in 10%, and cardiovascular problems in 5.8%. Mean follow-up was 38.4 +/- 10.2 months, range 25.2-61.1. There was no conversion to open surgery nor operative mortality. Early major complications were diagnosed in five patients (4.2%). Postoperatively, 118 patients were evaluated. Late major complications were observed in seven patients (5.9%). Reoperations were performed in six (5.1%). Mean postoperative BMI was 25.7 +/- 3.17 kg/m(2), and 86.4% were no longer obese. Mean %EWL was 84.5 +/- 19.5%. Hypertension was resolved in 88.4% of the patients, dyslipidemia in 82.3%, and T2DM in 84.2%. The LII-SG provided an adequate weight loss and resolution of associated diseases during mid-term outcomes evaluation. There was an acceptable morbidity with no operative mortality. It seems that chronic ileal brake activation determined sustained reduced food intake and increased satiety over time. LII-SG could be regularly used as a surgical alternative for the treatment of morbid obesity.

This Letter presents a search at the LHC for s-channel single top-quark production in proton-proton collisions at a centre-of-mass energy of 8 TeV. The analyzed data set was recorded by the ATLAS detector and corresponds to an integrated luminosity of 20.3 fb−1. Selected events contain one charged lepton, large missing transverse momentum and exactly two b-tagged jets. A multivariate event classifier based on boosted decision trees is developed to discriminate s-channel single top-quark events from the main background contributions. The signal extraction is based on a binned maximum-likelihood fit of the output classifier distribution. The analysis leads to an upper limit on the s-channel single top-quark production cross-section of 14.6 pb at the 95% confidence level. The fit gives a cross-section of σs=5.0±4.3 pb, consistent with the Standard Model expectation.

Results of a search for new phenomena in final states with an energetic jet and large missing transverse momentum are reported. The search uses 20.3 fb−1 of s√=8 TeV data collected in 2012 with the ATLAS detector at the LHC. Events are required to have at least one jet with pT>120 GeV and no leptons. Nine signal regions are considered with increasing missing transverse momentum requirements between EmissT>150 GeV and EmissT>700 GeV. Good agreement is observed between the number of events in data and Standard Model expectations. The results are translated into exclusion limits on models with large extra spatial dimensions, pair production of weakly interacting dark matter candidates, and production of very light gravitinos in a gauge-mediated supersymmetric model. In addition, limits on the production of an invisibly decaying Higgs-like boson leading to similar topologies in the final state are presented.

P>To put constraints on the Mesozoic to recent growth of the Anti-Atlas system, we investigated the temperature-time history of rocks by applying extensive low-temperature thermochronological analysis to three Precambrian inliers along the coast and 250 km into the interior. Bedrocks yield old U-Th/He ages on zircon (248-193 Ma) and apatite (150-50 Ma) and also fission-track ages of 173-121 Ma on apatite. These datasets are interpreted as recording passive margin upward movements from central Atlantic rifting until the Early Cretaceous. A phase of sedimentary burial was evidenced for the Cretaceous-Eocene. The extension of this thin (1.5 km) basin is loosely constrained but can be extended to the western regions of northern Africa. Effects of the existing thermal perturbation of lithospheric origin 100 km below the Atlas show that the 120-60 degrees C isotherms are not much deflected. Large-scale uplift has possibly occurred in the western Anti-Atlas since c. 30 Ma and is associated with a mean denudation rate of 0.08 km Ma-1.

Elaborar un marco general con las caracter??sticas demogr??ficas y sociales de la mujer asturiana que pudiera servir para obtener una perspectiva gen??rica de sus condiciones de vida y para se??alar problemas y situaciones discriminatorias. Elaborar una base de datos sobre caracter??sticas demogr??ficas sociales y econ??micas de la mujer asturiana. Mujeres de Asturias. Se plantean 3 temas: caracter??sticas y comportamientos demogr??ficos de la mujer asturiana, relaciones entre mujer y educaci??n y la mujer y el mundo del trabajo. Se ha utilizado como punto de partida la hip??tesis de que las caracter??sticas sociodemogr??ficas de los hombres y de las mujeres son distintas, por lo que han hecho an??lisis comparativos para ponerlas de manifiesto. El enfoque del estudio es el geogr??fico, menos habitual que el sociol??gico, seg??n los autores esto es debido a su formaci??n. Para el an??lisis de desigualdades en raz??n del medio en que habitan, se atienden a dos criterios car??cter central o perif??rico de los concejos y medio rural o urbano. Se estudian las caracter??sticas demogr??ficas; el proceso de escolarizaci??n las diferencias espaciales de escolarizaci??n, la ense??anza universitaria, la no reglada y el grado de instrucci??n actual de la mujer y su relaci??n con la actividad que realiza. An??lisis de fuentes primarias como nomenclatores de poblaci??n, anuario estad??stico del INEM, fuentes in??ditas facilitadas por distintos organismos e instituciones p??blicas de la Sociedad Asturiana de Estudios Econ??micos y Sociales, la Universidad de Oviedo, la Direcci??n Regional de Funci??n P??blica, el INEM y la Direcci??n Regional de Salud P??blica. Se presentan dos bloques uno de texto que recoge las conclusiones m??s importantes acompa??ado de gr??ficos y otro de mapas que se presentan todos juntos para constituir un atlas capaz de reflejar a trav??s de im??genes las caracter??sticas sociales y demogr??ficas m??s importantes. Tras una descripci??n demogr??fica se abordan los otros dos temas educaci??n y empleo. A lo largo de las dos ??ltimas d??cadas se ha conseguido la equiparaci??n num??rica por sexos de quienes acceden a los distintos niveles educativos. Las desigualdades residen en el tipo de ense??anzas que cursan y por tanto en la cualificaci??n que adquieren para competir en el mercado laboral. La pervivencia de las diferencias se observa a??n al introducir la variable espacial. En cuanto al an??lisis: mujer y trabajo, cabe destacar el predominio de mujeres amas de casa, escasez de mujeres activas, importancia de los sectores primario y terciario, mayor importancia del desempleo, mayores obst??culos laborales, en conjunto alcanzan categor??as socioprofesionales inferiores adem??s de las escasas oportunidades de empleo en el sector terciario para mujeres que no residen en el centro de Asturias.
