Reflexiones al final de un inicio: estudio de asociación entre variables sociodemográficas y tipo d
2019
Objectives The aim of our work is to approach types of childbirth at the end of pregnancy from a sociodemographic point of view, w ith special emphasis in the number of C sections. Material and Method The birth data in Spain provided by the National Institute of Statistics has been analyzed. Results The results obtained from crossing the variables show that there are social determinants that should be considered in order to better understand the process of childbirth. Discussion Our approach goes beyond the mere description and aims to show a causality that should be included in obstetric protocols. Conclusion Health workers must be aware of the personal circumstances of the patients so tha…
Measurement of the muon neutrino inclusive charged-current cross section in the energy range of 1–3 GeV with the T2K INGRID detector
2016
International audience; We report a measurement of the $\nu_{\mu}$-nucleus inclusive charged current cross section (=$\sigma^{cc}$) on iron using data from exposed to the J-PARC neutrino beam. The detector consists of 14 modules in total, which are spread over a range of off-axis angles from 0$^\circ$ to 1.1$^\circ$. The variation in the neutrino energy spectrum as a function of the off-axis angle, combined with event topology information, is used to calculate this cross section as a function of neutrino energy. The cross section is measured to be $\sigma^{cc}(1.1\text{ GeV}) = 1.10 \pm 0.15$ $(10^{-38}\text{cm}^2/\text{nucleon})$, $\sigma^{cc}(2.0\text{ GeV}) = 2.07 \pm 0.27$ $(10^{-38}\te…
Framing Caesarean Section Reduction Policies Through a Dynamic Performance Management Approach: A Maternity Pathway Case-Based Analysis
2017
The World Health Organization since the last three decades strongly encourages countries to reduce the caesarean section (CS) rate down to 10–15%. However, this goal nowadays appears still far from its achievement. Public decision-makers are indeed struggling to design and implement effective policies to reduce the CS rate. The literature provides a wide range of factors causing a change in the CS rate, such as the patient clinical profile and the healthcare service quality provided. Maternity pathway (MP) is considered a mean through which to standardize the cares and to reduce CSs. This study investigates the MP recently introduced in Sicilian local health authorities. Based on such an an…
Current Role of Intraoperative Frozen Section Examination of Sentinel Lymph Node in Early Breast Cancer.
2020
Background/Aim: The aim of this study was to evaluate the current role of frozen section in identifying patients who could benefit from an immediate axillary lymph node dissection (ALND), following the criteria of the ASOCOG Z0011 and IBCSG 23-10 trials. Patients and Methods: A retrospective review was performed involving 2,079 patients with early breast cancer who underwent conservative surgery or total mastectomy with sentinel lymph node biopsy. Results: Sensitivity and diagnostic accuracy were 63.8% and 90.3%, respectively. Sensitivity was significantly higher (p<0.001) in finding macrometastases (81.8%) compared to micrometastases (11.9%). Frozen section was useful only in 7.7% of th…
Geographical mapping of metabolites in biological tissue with quantitative bioluminescence and single photon imaging
1993
This article features a novel technique for measuring the spatial distribution of metabolites, such as ATP, glucose, and lactate, in rapidly frozen tissue. Concentration values are obtained in absolute terms and with a spatial resolution of single-cell dimension. The method is based on enzymatic reactions that link the metabolite of interest to luciferase with subsequent light emission. Using a specific array, cryosections are brought into contact with the enzymes in a well-defined, reproducible way inducing a distribution of light across the section with an intensity that is proportional to the metabolite concentration. The emitted light can be visualized through a microscope and an imagin…
Drawings for engineering
2012
In the representation of knowledge can not miss all those geometric, static, functional, and specialized notions in infrastructures that characterize the shape of a Civil Engineer. We take this opportunity to show how complex the representation of a hydraulic overflow, how bold is the company wanting to bring the cross sections, the view from above, the longitudinal section. And, yet how essential is the knowledge of descriptive geometry to determine the intersections of complex surfaces, the application of engineering has great feedback. An engineer must know how to read and know how to make a drawing, must learn to identify the main characteristics, must be able to focus on the goals and …
Las peculiaridades de las secciones de crédito de las cooperativas: sus repercusiones en el caso valenciano
1999
El presente artículo tiene por objeto analizar en qué medida las especificidades jurídicas y económicas de las secciones de crédito de las cooperativas condicionan su actividad bancaria. Aunque no tengan consideración de entidades de crédito, estas secciones prestan servicios de depósito, pago y crédito a sus socios. No obstante, las limitaciones existentes para el desarrollo de la actividad crediticia y las especiales características del negocio financiero afectan de forma directa en el desarrollo de estas secciones. Esta serie de condicionantes obliga a prestar especial atención a la vigilancia de estas cooperativas, al igual que se realiza con el conjunto de empresas bancarias, a fin de …
A bioluminescence technique for quantitative and structure-associated imaging of pyruvate
2006
A novel bioluminescence assay has been developed for measuring pyruvate within sections of snap-frozen tissue in a quantitative manner as well as with a spatial resolution on a microscopical level. The assay was verified via HPLC and two independent photometric tests. The novel assay makes it possible to determine pyruvate concentrations in cryosections in the range of 0-5.0 micromol/g tissue (dry weight). Based on the analysis of samples of given pyruvate concentrations, the assay exhibits a recovery with a deviationor =15%. The minimal detectable amount was 0.02 pmol based on a 20 microm thick tissue section with an area of 1 cm(2). Combination of the already established imaging biolumine…
Fragilità e situazioni carcerarie tra circuiti, sezioni protette e diritti negati
2023
Uno sguardo alle funzioni del carcere attraverso la lente della fragilità consente di mettere in luce i limiti dell’attuale sistema penitenziario invitando l’interprete a riflettere su possibili soluzioni per contenerne i noti effetti negativi. L’organizzazione degli spazi, tra circuiti, sezioni e regimi, è espressione di come negli anni sia prevalsa la preoccupazione per la sicurezza, finendo, questa, per assorbire la rieducazione e la tutela di tanti diritti dei detenuti. A look at the functions of the prison through the lens of fragility allows us to highlight the limits of the current penitentiary system, inviting the interpreter to reflect on possible solutions to contain its known neg…
Search for high-mass resonances decaying to dimuons at CDF.
2009
We present a search for high-mass neutral resonances using dimuon data corresponding to an integrated luminosity of 2.3 fb(-1) collected in pp collisions at s=1.96 TeV by the CDF II detector at the Fermilab Tevatron. No significant excess above the standard model expectation is observed in the dimuon invariant-mass spectrum. We set 95% confidence level upper limits on sigma BR(pp -> X ->mu mu), where X is a boson with spin-0, 1, or 2. Using these cross section limits, we determine lower mass limits on sneutrinos in R-parity-violating supersymmetric models, Z(') bosons, and Kaluza-Klein gravitons in the Randall-Sundrum model.
