Helicobacter pylori (H. pylori), clasificada como carcinógeno tipo I para cáncer gástrico (CG), ha acompañado al hombre al menos desde hace 116 000 años. Los conocimientos de las fuerzas evolutivas que modulan el rol de esta bacteria en el desarrollo del espectro de enfermedades gástricas son aún escasos. Esta revisión sistemática recopila artículos que reportan un proceso de coevolución, relacionan los componentes ancestrales huésped-hospedero y describen mecanismos adaptativos de H. pylori al entorno gástrico humano, con el fin de comprender si el proceso de coevolución modula la patogenicidad de la bacteria y el desarrollo de enfermedades gástricas. Se realizó una búsqueda sistemática en las bases de datos electrónicas: MEDLINE (OvidSP), Scopus (ScienceDirect), Scielo y Tree of Science (ToS); términos de búsqueda: "stomach", "cancer", "neoplasms", "ethinicity", "evolution", "genetics", "ancestry" y "Helicobacter pylori". Idiomas: inglés y español. Los datos fueron filtrados por un revisor utilizando un formulario estándar de extracción y ulteriormente revisados por otro. El riesgo de sesgo y la calidad metodológica de los estudios fueron evaluadas con el programa: Critical Appraisal Skills Programme (CASP). Del total de 1584 estudios, 36 cumplieron los criterios de inclusión. Los factores más relevantes en el desarrollo del espectro de enfermedades asociadas con la infección por H. pylori son: la disrupción en el proceso de coevolución entre la bacteria y su huésped humano -por la transferencia horizontal de segmentos de genes que no han evolucionado con sus anfitriones-; las sustituciones de aminoácidos; la fijación y la selección positiva principalmente en las regiones hipervariables. Helicobacter pylori (H. pylori) is classified as carcinogen type I for gastric cancer (GC). Although it has accompanied man for at least 116,000 years, knowledge of the evolutionary forces that modulate the role of this bacterium within the development of the spectrum of gastric diseases is still scarce. This systematic review compiles articles that report a process of coevolution process, relate host-host ancestral components, and describe H. pylori’s mechanisms of adaptation to the human gastric environment in order to understand if coevolution has modulated the pathogenicity of these bacteria and the development of gastric diseases. A systematic search was carried out in MEDLINE (OvidSP), Scopus (ScienceDirect), Scielo and Tree of Science (ToS). The following search terms were used: "Stomach", "Cancer", "Neoplasms", "Ethinicity", "Evolution", "Genetics", "Ancestry" and "Helicobacter pylori", and searches were conducted in both English and Spanish. The data were filtered by one reviewer using a standard extraction form and then reviewed by another. The risk of bias and the methodological quality of the studies were evaluated using the Critical Appraisal Skills Program (CASP). Thirty-six of the total 1,584 studies found met the inclusion criteria. The most relevant factors in the development of the spectrum of diseases associated with H. pylori infection are amino acid substitutions, binding and positive selection mainly in the hypervariable regions, and disruption of the coevolution process between the bacteria and their human hosts as the result of horizontal transfer of gene segments that did not evolve with their host.

AkvaGIS is a novel, free and open source module included in the FREEWAT plugin for QGIS that supplies a standardized and easy-to-use workflow for the storage, management, visualization and analysis of hydrochemical and hydrogeological data. The main application is devised to simplify the characterization of groundwater bodies for the purpose of building rigorous and data-based environmental conceptual models (as required in Europe by the Water Framework Directive). For data-based groundwater management, AkvaGIS can be used to prepare input files for most groundwater flow numerical models in all of the available formats in QGIS. AkvaGIS is applied in the Walloon Region (Belgium) to demonstrate its functionalities. The results support a better understanding of the hydrochemical relationship among aquifers in the region and can be used as a baseline for the development of new analyses, e.g., further delineation of nitrate vulnerable zones and management of the monitoring network to control chemical spatial and temporal evolution. AkvaGIS can be expanded and adapted for further environmental applications as the FREEWAT community grows. © 2018 The Authors, Funding text This paper is presented within the framework of the project FREEWAT , which received funding from the European Union’s Horizon 2020 research and innovation programme under Grant Agreement n. 642224 .

- Abstract
Canine Distemper Virus (CDV) is a highly contagious virus that can cross mammalian species barriers and has widespread impacts on both domestic animals and wildlife populations. This study describes a recent outbreak of CDV in the Galapagos Islands in 2019. A total number of 125 dogs with clinical signs compatible with CDV were included in this study. Nasal swabs were taken and analyzed by RT-qPCR for the detection of CDV, resulting in a positivity rate of 74.4% (IC95%, 66-81%). Among the CDV positive dogs, 82.2% presented with respiratory signs, 48.8% neurological signs, and 28.9% gastrointestinal signs. CDV has been previously reported in the domestic canine population of the Galapagos Islands in 2001 and 2004. The current study shows how CDV is still a threat for the endemic and endangered Galapagos sea lion, despite recent policies for dog population control and CDV vaccination., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Vega-Mariño, Olson, Howitt, Criollo, Figueroa, Orlando, Cruz and Garcia-Bereguiain.)

Hassanzadeh A, Valdivielso S, Vázquez-Suñé E, Criollo R, and Corbella M
- Abstract
Isotopic composition modelling is a key aspect in many environmental studies. This work presents Isocompy, an open source Python library that estimates isotopic compositions through machine learning algorithms with user-defined variables. Isocompy includes dataset preprocessing, outlier detection, statistical analysis, feature selection, model validation and calibration and postprocessing. This tool has the flexibility to operate with discontinuous inputs in time and space. The automatic decision-making procedures are knitted in different stages of the algorithm, although it is possible to manually complete each step. The extensive output reports, figures and maps generated by Isocompy facilitate the comprehension of stable water isotope studies. The functionality of Isocompy is demonstrated with an application example involving the meteorological features and isotopic composition of precipitation in N Chile, which are compared with the results produced in previous studies. In essence, Isocompy offers an open source foundation for isotopic studies that ensures reproducible research in environmental fields., (© 2023. The Author(s).)

- Abstract
This research presents the occurrence and fate of 121 contaminants of emerging concern (CECs) in an urban aquifer polluted by river recharge through a data-base modelling. Afterwards, risk quotients (RQs) are computed to determine the risk posed by CECs to human health. To this end, groundwater and river water samples were collected in four campaigns conducted from February to May 2021. Results show that 46 CECs are ubiquitous in groundwater and their concentrations vary several orders of magnitude, ranging from below the limit of quantification to 44.5·10
3 ng/L for iopamidol. Transformation products (TPs) are usually detected at lower concentrations than those of the parent substances but there are some exceptions (i.e., fipronil sulphide, fipronil sulfone and O-desmethylvenlafaxine). River concentrations are higher than those detected in groundwater for some CECs, indicating the occurrence of natural attenuation processes when river water infiltrates the aquifer. A data-based advection-reaction modelling is proposed and tested for ca. 40 substances with detection frequencies higher than 90%. It provides useful quantitative information regarding the dynamic behaviour of the variables monitored, expressed in terms of characteristic length, entropy and synchronized state contribution. Finally, risk quotients (RQs) are used to assess the human health risk posed by the ubiquitous CECs in groundwater. Most CECs do not pose any risk to the different life stages considered, as the RQs evaluated are lower than 0.01. However, the pharmaceuticals valsartan and its TP valsartan acid show RQs higher than 1, indicating that these substances might be harmful to human beings., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 The Authors.

18. Quantification of groundwater recharge in urban environments.

- Abstract
Groundwater management in urban areas requires a detailed knowledge of the hydrogeological system as well as the adequate tools for predicting the amount of groundwater and water quality evolution. In that context, a key difference between urban and natural areas lies in recharge evaluation. A large number of studies have been published since the 1990s that evaluate recharge in urban areas, with no specific methodology. Most of these methods show that there are generally higher rates of recharge in urban settings than in natural settings. Methods such as mixing ratios or groundwater modeling can be used to better estimate the relative importance of different sources of recharge and may prove to be a good tool for total recharge evaluation. However, accurate evaluation of this input is difficult. The objective is to present a methodology to help overcome those difficulties, and which will allow us to quantify the variability in space and time of the recharge into aquifers in urban areas. Recharge calculations have been initially performed by defining and applying some analytical equations, and validation has been assessed based on groundwater flow and solute transport modeling. This methodology is applicable to complex systems by considering temporal variability of all water sources. This allows managers of urban groundwater to evaluate the relative contribution of different recharge sources at a city scale by considering quantity and quality factors. The methodology is applied to the assessment of recharge sources in the Barcelona city aquifers., (Copyright © 2017 Elsevier B.V. All rights reserved.)
