Prevalencia de candidiasis vaginal en una población obstétrica de bajo riesgo en Santander

ObjetivoConocer la prevalencia de candidiasis vaginal en embarazadas controladas desde atención primaria y ver si está aumentando con el paso del tiempo.DiseñoEstudio descriptivo, retrospectivo del universo de mujeres embarazadas.EmplazamientoZona Básica de Salud Cazoña (34.783 habitantes).SujetosToda la población obstétrica controlada en nuestro centro de salud desde 1992 a 1997, ambos inclusive.Mediciones y resultadosEstudio retrospectivo de las historias clínicas de todas las mujeres embarazadas captadas en nuestro centro de salud (878 embarazos). Descartados los derivados a tocólogo, abortos y partos prematuros, se han valorado 549 embarazos (62,30% del total) normales, de bajo riesgo, controlados hasta el final por atención primaria, con un rango de edad de 16-40 años. La prevalencia media de candidiasis es de un 18% (IC, 15,0-21,6). Su frecuencia aumenta a medida que se incrementa el número de gestaciones y disminuye a medida que aumenta la edad de la embarazada.ConclusionesLa prevalencia encontrada en nuestro estudio es de un 18%, y no está aumentando a medida que pasan los años.ObjectivesTo find the prevalence of vaginal candidiasis in pregnant women monitored through primary care and to see whether it is on the increase.DesignDescriptive and retrospective study of pregnant women.SettingCazoña Health District (34783 inhabitants).SubjectsThe entire obstetric population monitored by our health centre between 1992 and 1997 inclusive.Measurements and resultsRetrospective study of clinical histories of all the pregnant women seen at our health centre (878 pregnancies). After discounting those referred to obstetricians, abortions/ miscarriages and premature births, 549 normal low-risk pregnancies (62.30% of the total) were monitored to completion in primary care. The women's age range was 16 to 40. The mean prevalence of candidiasis was 18% (CI, 15.0-21.6). Its frequency increased as the number of pregnancies increased and dropped as the age of the pregnant women increased.ConclusionsPrevalence found in our study was 18% and did not increase as the years passed

Supernova Pointing Capabilities of DUNE

International audienceThe determination of the direction of a stellar core collapse via its neutrino emission is crucial for the identification of the progenitor for a multimessenger follow-up. A highly effective method of reconstructing supernova directions within the Deep Underground Neutrino Experiment (DUNE) is introduced. The supernova neutrino pointing resolution is studied by simulating and reconstructing electron-neutrino charged-current absorption on $^{40}$Ar and elastic scattering of neutrinos on electrons. Procedures to reconstruct individual interactions, including a newly developed technique called ``brems flipping'', as well as the burst direction from an ensemble of interactions are described. Performance of the burst direction reconstruction is evaluated for supernovae happening at a distance of 10 kpc for a specific supernova burst flux model. The pointing resolution is found to be 3.4 degrees at 68% coverage for a perfect interaction-channel classification and a fiducial mass of 40 kton, and 6.6 degrees for a 10 kton fiducial mass respectively. Assuming a 4% rate of charged-current interactions being misidentified as elastic scattering, DUNE's burst pointing resolution is found to be 4.3 degrees (8.7 degrees) at 68% coverage

Performance of a modular ton-scale pixel-readout liquid argon time projection chamber

International audienceThe Module-0 Demonstrator is a single-phase 600 kg liquid argon time projection chamber operated as a prototype for the DUNE liquid argon near detector. Based on the ArgonCube design concept, Module-0 features a novel 80k-channel pixelated charge readout and advanced high-coverage photon detection system. In this paper, we present an analysis of an eight-day data set consisting of 25 million cosmic ray events collected in the spring of 2021. We use this sample to demonstrate the imaging performance of the charge and light readout systems as well as the signal correlations between the two. We also report argon purity and detector uniformity measurements, and provide comparisons to detector simulations

First Measurement of the Total Inelastic Cross-Section of Positively-Charged Kaons on Argon at Energies Between 5.0 and 7.5 GeV

International audienceProtoDUNE Single-Phase (ProtoDUNE-SP) is a 770-ton liquid argon time projection chamber that operated in a hadron test beam at the CERN Neutrino Platform in 2018. We present a measurement of the total inelastic cross section of charged kaons on argon as a function of kaon energy using 6 and 7 GeV/$c$ beam momentum settings. The flux-weighted average of the extracted inelastic cross section at each beam momentum setting was measured to be 380$\pm$26 mbarns for the 6 GeV/$c$ setting and 379$\pm$35 mbarns for the 7 GeV/$c$ setting
