    Abstract El espacio geográfico es localizable y se representa por medio de productos cartográficos, siendo estos una herramienta fundamental para la visualización de los fenómenos del lugar. El presente trabajo tiene como objetivo analizar las transformaciones espaciales de la Delegación Municipal de General Daniel Cerri, en base al análisis visual de cartografía a escala 1:50.000, para el período comprendido entre 1967 y 2008. La misma se localiza en el oeste de la ciudad de Bahía Blanca ubicada en el suroeste de la Provincia de Buenos Aires. El presente estudio forma parte del proyecto “La digitalización y actualización de la carta topográfica de Bahía Blanca a escala 1: 50.000”. La metodología de este trabajo se basa en la aplicación de técnicas de producción de cartografía digital, relevamiento en el terreno y la consulta a diversas fuentes de información cartográfica como son las fotos aéreas, la carta topográfica, los planos de los sectores y las imágenes satelitales entre otras. La delegación en estudio comprende la localidad de General Cerri y los siguientes barrios: Los Chañares, Villa Bordeu y Don Ramiro. La expansión de la ciudad de Bahía Blanca en las últimas cuatro décadas ha generado nuevos espacios y modificado las áreas ya existentes, en la delegación cabe destacar el crecimiento del barrio Los Chañares que se convierte en un área residencial de baja densidad, el desarrollo de dos franjas comerciales a lo largo de las rutas nacionales Nº 35 y Nº 3 Sur, y el estancamiento del área comprendida por la localidad de General Cerri que sufre deterioros económicos y mantiene la característica de área periférica y hortícola.

    Abstract Distribution, accumulation and diagenesis of surficial sediments in coastal and continental shelf systems follow complex chains of localized processes and form deposits of great spatial variability. Given the environmental and economic relevance of ocean margins, there is growing need for innovative geophysical exploration methods to characterize seafloor sediments by more than acoustic properties. A newly conceptualized benthic profiling and data processing approach based on controlled source electromagnetic (CSEM) imaging permits to coevally quantify the magnetic susceptibility and the electric conductivity of shallow marine deposits. The two physical properties differ fundamentally insofar as magnetic susceptibility mostly assesses solid particle characteristics such as terrigenous or iron mineral content, redox state and contamination level, while electric conductivity primarily relates to the fluid-filled pore space and detects salinity, porosity and grain-size variations. We develop and validate a layered half-space inversion algorithm for submarine multifrequency CSEM with concentric sensor configuration. Guided by results of modeling, we modified a commercial land CSEM sensor for submarine application, which was mounted into a nonconductive and nonmagnetic bottom-towed sled. This benthic EM profiler Neridis II achieves 25 soundings/second at 3-4 knots over continuous profiles of up to hundred kilometers. Magnetic susceptibility is determined from the 75 Hz in-phase response (90% signal originates from the top 50 cm), while electric conductivity is derived from the 5 kHz out-of-phase (quadrature) component (90% signal from the top 92 cm). Exemplary survey data from the north-west Iberian margin underline the excellent sensitivity, functionality and robustness of the system in littoral (~0-50 m) and neritic (~50-300 m) environments. Susceptibility vs. porosity cross-plots successfully identify known lithofacies units and their transitions. All presently available data indicate an eminent potential of CSEM profiling for assessing the complex distribution of shallow marine surficial sediments and for revealing climatic, hydrodynamic, diagenetic and anthropogenic factors governing their formation.

    Abstract The coastal systems, are often subjected to high anthropogenic pressure, which makes it necessary to develop new techniques to assess the environmental impacts caused by such human activity. This paper presents the first results obtained during the development and implementation of a new equipment of submarine geophysics survey oriented to integrated coastal zone management (ICZM). It is based on the drag of a submarine in contact with the sea-bottom. The submarine is equipped with an electromagnetic sensor which allows the measurement of the magnetic susceptibility and electrical conductivity of the surface sediments continuously and to a depth of sediment of 40 cm. This system, once improved, will allow us to obtain valuable information for monitoring the environmental quality of coastal areas.

    Abstract Aims: Treatment with dihydropyrimidines poses a significant risk of serious adverse reactions for patients with dihydropyrimidine dehydrogenase (DPD) deficiency. This study seeks to analyse the correlation between DPD deficiency and plasmatic uracil values in patients who are candidates for a fluoropyrimidine scheme. It also studies the incidence of adverse events (AEs) in patients with DPD deficiency established with plasmatic uracil determination.
    Methods: This was a retrospective observational study conducted in a tertiary level establishment from September 2020 to April 2021. Patients included were diagnosed with gastrointestinal tumours, were of good status, and were initiated into a fluoropyrimidine-based regimen. The incidence and grade of AEs, according Common Terminology Criteria for Adverse Events (CTCAE), were collected and compared in patients with and without DPD deficiency.
    Results: 119 patients diagnosed with gastrointestinal cancer met the inclusion criteria. In 92 (77%) patients there was no DPD deficiency according to plasmatic uracil thresholds. In the group of patients without deficit, dose reductions oscillated between 10-25% (mean 17.4%). In the no DPD deficiency group, 43 (46%) patients experienced AEs. Patients who had a DPD deficiency according to plasmatic uracil measurements were started on a 5-fluorouracil (5-FU) regimen with a dose reduction of 15-50% (mean 35%). In this group, 12 patients (44%) experienced some AEs.
    Conclusion: New research is needed to clarify the correlation between plasma uracil values and DPD deficiency to achieve an optimal balance between clinical benefit and toxicity.

    Abstract Imaging plays an important role in the diagnosis of spinal infections. Early diagnosis is paramount in the treatment of spinal infections and leads to improved outcomes. This article reviews the imaging and relevant clinical details of infections of the spine: pyogenic spondylodiscitis, tuberculous spondylodiscitis, septic facet arthritis, epidural abscess, and subdural abscess. Though radiographs can reveal subtle changes with infections, advanced imaging modalities have increased sensitivity to aid in early diagnosis. Magnetic resonance imaging (MRI) is emphasized given it is generally the most sensitive and specific advanced imaging modality. However, nuclear medicine imaging and computer tomography (CT) play a role diagnosis in cases where MRI is not available or contra-indicated. Additionally, CT is also important for image-guided biopsy to guide antimicrobial treatment.
