    Climate change impacts represent threats to the population worldwide, and the health sector which is responsible for taking care of their life and health will also be impacted. While the consequences of these impacts are imminent, little or nothing has been done by the health sector at national and sub-national levels worldwide to prepare to respond to them. Therefore, health adaptation planning in regard to climate change is crucial to building climate-resilient health systems. This research aims to propose an approach containing phases and steps for developing a Health Adaptation Plan at a sub-national level. The methodology involved the collection and analysis of several guidelines and tools provided by the WHO and other relevant organisations,. This is supplemented by analysis of existing Health Adaptation Plans at national and subnational levels developed in different governmental organisations and systems worldwide since 2003. The findings included four phases and twelve steps for developing Health Adaptation Plans at subnational- level organisations in the health sector. This establishes guidance for subnational organisations within the health sector that are planning to develop a Health Adaptation Pla

    Planetary Radio Interferometry and Doppler Experiment (PRIDE) Technique: a Test Case of the Mars Express Phobos Fly-by. 2. Doppler tracking: Formulation of observed and computed values, and noise budget

    Context. Closed-loop Doppler data obtained by deep space tracking networks (e.g., NASA's DSN and ESA's Estrack) are routinely used for navigation and science applications. By "shadow tracking" the spacecraft signal, Earth-based radio telescopes involved in Planetary Radio Interferometry and Doppler Experiment (PRIDE) can provide open-loop Doppler tracking data when the dedicated deep space tracking facilities are operating in closed-loop mode only. Aims. We explain in detail the data processing pipeline, discuss the capabilities of the technique and its potential applications in planetary science. Methods. We provide the formulation of the observed and computed values of the Doppler data in PRIDE tracking of spacecraft, and demonstrate the quality of the results using as a test case an experiment with ESA's Mars Express spacecraft. Results. We find that the Doppler residuals and the corresponding noise budget of the open-loop Doppler detections obtained with the PRIDE stations are comparable to the closed-loop Doppler detections obtained with the dedicated deep space tracking facilities

    La ciudad de Trenque Lauquen en la provincia de Buenos Aires, Argentina se abastece exclusivamente del recurso hídrico subterráneo. El objetivo del trabajo es analizar la evolución temporal en la calidad fisicoquímica del agua, teniendo en cuenta las características hidrogeológicas y los procesos con la matriz sólida. La metodología consistió en la valoración y síntesis de la información geológica, geofísica, hidrogeológica e hidroquímica y la modelación de procesos hidrogeoquímicos. El agua del acuífero incrementa su salinidad con la profundidad de explotación y evoluciona hacia una disolución de yeso y precipitación de calcita, con el consiguiente incremento del contenido de sulfatos y de dureza. Se consideran apropiadas las medidas de gestión en los últimos años, que condujeron a realizar perforaciones más someras y con menor caudal de extracción, lo que ha permitido que la tendencia creciente a la salinización haya disminuido su tasa de evolución, mejorando la calidad del agua subterránea.The city of Trenque Lauquen in the Buenos Aires Province, Argentina, gets water supply ex-clusively from groundwater resources. The goal of this study is to analyze time trends related to water quality, taking into account hydrogeological characteristics and processes with the solid matrix. The methodology consisted in the assessment and summary of geological, geophysical, hydrogeological and hydrochemical in-formation, and hydrogeochemical modelling. Groundwater salinity increases with the depth of exploitation and evolves into a gypsum dissolution and calcite precipitation, increasing sulphate content and hardness. Water management measures in recent years, based on shallow wells and lower extraction volumes became appropriate since the rate of salinization has decreased improving groundwater quality

    Miro: A molecular switch at the center of mitochondrial regulation

    Full text link
    The orchestration of mitochondria within the cell represents a critical aspect of cell biology. At the center of this process is the outer mitochondrial membrane protein, Miro. Miro coordinates diverse cellular processes by regulating connections between organelles and the cytoskeleton that range from mediating contacts between the endoplasmic reticulum and mitochondria to the regulation of both actin and microtubule motor proteins. Recently, a number of cell biological, biochemical, and protein structure studies have helped to characterize the myriad roles played by Miro. In addition to answering questions regarding Miro’s function, these studies have opened the door to new avenues in the study of Miro in the cell. This review will focus on summarizing recent findings for Miro’s structure, function, and activity while highlighting key questions that remain unanswered.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/155476/1/pro3839.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/155476/2/pro3839_am.pd

    Epidemiology and spatio‐temporal analysis of West Nile virus in horses in Spain between 2010 and 2016

    During the last decade, West Nile virus (WNV) outbreaks have increased sharply in both horses and human in Europe. The aims of this study were to evaluate characteristics and spatio‐temporal distribution of WNV outbreaks in horses in Spain between 2010 and 2016 in order to identify the environmental variables most associated with WNV occurrence and to generate high‐resolution WNV suitability maps to inform risk‐based surveillance strategies in this country. Between August 2010 and November 2016, a total of 403 WNV suspected cases were investigated, of which, 177 (43.9%) were laboratory confirmed. Mean values of morbidity, mortality and case fatality rates were 7.5%, 1.6% and 21.2%, respectively. The most common clinical symptoms were as follows: tiredness/apathy, recumbency, muscular tremor, ataxia, incoordination and hyperaesthesia. The outbreaks confirmed during the last 7 years, with detection of WNV RNA lineage 1 in 2010, 2012, 2013, 2015 and 2016, suggest an endemic circulation of the virus in Spain. The spatio‐temporal distribution of WNV outbreaks in Spain was not homogeneous, as most of them (92.7%) were concentrated in western part of Andalusia (southern Spain) and significant clusters were detected in this region in two non‐consecutive years. These findings were supported by the results of the space–time scan statistics permutation model. A presence‐only MaxEnt ecological niche model was used to generate a suitability map for WNV occurrence in Andalusia. The most important predictors selected by the Ecological Niche Modeling were as follows: mean annual temperature (49.5% contribution), presence of Culex pipiens (19.5% contribution), mean annual precipitation (16.1% contribution) and distance to Ramsar wetlands (14.9% contribution). Our results constitute an important step for understanding WNV emergence and spread in Spain and will provide valuable information for the development of more cost‐effective surveillance and control programmes and improve the protection of horse and human populations in WNV‐endemic areas.info:eu-repo/semantics/acceptedVersio

    Understanding spatio-temporal variability in the reproduction ratio of the bluetongue (BTV-1) epidemic in southern Spain (Andalusia) in 2007 using epidemic trees

    Andalusia (Southern Spain) is considered one of the main routes of introduction of bluetongue virus (BTV) into Europe, evidenced by a devastating epidemic caused by BTV-1 in 2007. Understanding the pattern and the drivers of BTV-1 spread in Andalusia is critical for effective detection and control of future epidemics. A long-standing metric for quantifying the behaviour of infectious diseases is the case-reproduction ratio (Rt), defined as the average number of secondary cases arising from a single infected case at time t (for t>0). Here we apply a method using epidemic trees to estimate the between-herd case reproduction ratio directly from epidemic data allowing the spatial and temporal variability in transmission to be described. We then relate this variability to predictors describing the hosts, vectors and the environment to better understand why the epidemic spread more quickly in some regions or periods. The Rt value for the BTV-1 epidemic in Andalusia peaked in July at 4.6, at the start of the epidemic, then decreased to 2.2 by August, dropped below 1 by September (0.8), and by October it had decreased to 0.02. BTV spread was the consequence of both local transmission within established disease foci and BTV expansion to distant new areas (i.e. new foci), which resulted in a high variability in BTV transmission, not only among different areas, but particularly through time, which suggests that general control measures applied at broad spatial scales are unlikely to be effective. This high variability through time was probably due to the impact of temperature on BTV transmission, as evidenced by a reduction in the value of Rt by 0.0041 for every unit increase (day) in the extrinsic incubation period (EIP), which is itself directly dependent on temperature. Moreover, within the range of values at which BTV-1 transmission occurred in Andalusia (20.6°C to 29.5°C) there was a positive correlation between temperature and Rt values, although the relationship was not linear, probably as a result of the complex relationship between temperature and the different parameters affecting BTV transmission. Rt values for BTV-1 in Andalusia fell below the threshold of 1 when temperatures dropped below 21°C, a much higher threshold than that reported in other BTV outbreaks, such as the BTV-8 epidemic in Northern Europe. This divergence may be explained by differences in the adaptation to temperature of the main vectors of the BTV-1 epidemic in Andalusia (Culicoides imicola) compared those of the BTV-8 epidemic in Northern Europe (Culicoides obsoletus). Importantly, we found that BTV transmission (Rt value) increased significantly in areas with higher densities of sheep. Our analysis also established that control of BTV-1 in Andalusia was complicated by the simultaneous establishment of several distant foci at the start of the epidemic, which may have been caused by several independent introductions of infected vectors from the North of Africa. We discuss the implications of these findings for BTV surveillance and control in this region of Europe

    Emotional cues enhance the attentional effects on spatial and temporal resolution

    In the present study, we demonstrated that the emotional significance of a spatial cue enhances the effect of covert attention on spatial and temporal resolution (i.e., our ability to discriminate small spatial details and fast temporal flicker). Our results indicated that fearful face cues, as compared with neutral face cues, enhanced the attentional benefits in spatial resolution but also enhanced the attentional deficits in temporal resolution. Furthermore, we observed that the overall magnitudes of individuals’ attentional effects correlated strongly with the magnitude of the emotion × attention interaction effect. Combined, these findings provide strong support for the idea that emotion enhances the strength of a cue’s attentional response

    En el último siglo se ha notado de manera significativa el progreso de la técnica de nado en los atletas y esto se debe a estudios científicos que han aportado países como Holanda, Alemania, España y E.U.A, los cuales brindan a los nadadores estudios biomecánicos para mejorar su técnica. Mientras tanto en México, según nuestro conocimiento se proporciona poco apoyo para los atletas que quieren mejorar su rendimiento para llegar a competir en eventos internacionales como las olimpiadas. El presente trabajo tiene como objetivo presentar un proyecto que apoye a la mejora del rendimiento de estos atletas. “Biomecánica en la Natación” se encarga de monitorear y analizar principalmente los movimientos y procesos que hace el cuerpo humano para lograr desplazarse en medio acuático. Consiste en un estudio que analiza y compara en el tiempo la técnica de nado mediante sensores de movimiento, los cuales arrojan simulaciones 3D en forma de avatares y datos de posición y movimiento de diferentes regiones de interés (por sus siglas en inglés ROI, Regions of Interest) en el cuerpo humano. Además, se complementa el análisis de movimiento con el software KINOVEA TM para la medición de datos biométricos de los participantes y el análisis e interpretación de vídeos tomados durante las sesiones de evaluación. También se realizarán tomas de frecuencia cardiaca la cual medirá si existe un aumento o descenso del ritmo. Otra prueba para realizar será la prueba de lactato, la cual se utiliza para determinar la capacidad anaeróbica de un atleta.ITESO, A.C

    Animal assisted interventions in neurorehabilitation: a review of the most recent literature

    Get PDF
    Introduction: While conventional wisdom has always affirmed the value of animals in promoting human health and well-being, only recently has their therapeutic role in medicine become a topic for dedicated research. Animal assisted interventions (AAI) can be classified as animal-assisted activities, animal-assisted therapy, and service animal programmes. Objective: The aim of this review is to analyse original papers addressing AAI and neurological diseases and published in the most influential medical journals between 2001 and 2012, and discuss their findings in the light of what may be of interest in the field of neurology. Discussion: We selected a total of 23 articles on neurorehabilitation in cerebral palsy, pervasive developmental disorders, multiple sclerosis, spinal cord injury, stroke, and mental disorders. The main therapeutic results were improvement on the Gross Motor Function Classification Scale and in upper limb dexterity (cerebral palsy); improvement in social functioning and interaction; reductions in stress, anxiety, and loneliness (pervasive developmental disorders and mental disorders); and decreased spasticity with improved balance (multiple sclerosis, spinal cord injury, stroke). Conclusion: These interventions, performed with highly specialised animals in very specific neurological populations, deliver an increasing body of scientific evidence suggesting that they are an effective complement to other existing therapies. In these diseases, further high-quality studies are warranted in order to define the most appropriate programmes for therapy. Resumen: Introducción: Aunque siempre se ha afirmado el valor de los animales en la promoción del bienestar y la salud del ser humano, solo recientemente su papel terapéutico en medicina se ha convertido en el foco de investigación especializada. Las intervenciones asistidas por animales pueden dividirse en actividades asistidas por animales, terapia asistida por animales y programas de animales de servicio. Objetivo: El objetivo de esta revisión es analizar las publicaciones realizadas entre 2001 y 2012 en las revistas médicas más importantes, relacionadas con el campo de la rehabilitación de las enfermedades neurológicas, y discutir estos hallazgos a la luz de lo que pueda ser de interés para la neurología. Discusión: Se seleccionaron un total de 23 artículos de intervenciones en el campo de la parálisis cerebral infantil, trastornos generalizados del desarrollo, esclerosis múltiple, lesión medular, accidente cerebrovascular y trastornos mentales. Los principales resultados terapéuticos fueron: mejoría en la Gross Motor Function y en el manejo del miembro superior (parálisis cerebral infantil); aumento de la socialización y el contacto con el medio ambiente, reducción del estrés y la ansiedad y sentimientos de soledad (trastornos generalizados del desarrollo y trastornos mentales); disminución de la espasticidad y mejoría del equilibrio (esclerosis múltiple, lesión medular, accidente cerebrovascular). Conclusiones: Estas intervenciones asistidas con un tipo de animales muy limitado utilizadas en grupos clínicos neurológicos muy específicos muestran cada vez más pruebas científicas, como método complementario a otras terapias ya existentes. En estas enfermedades, se necesitan más estudios de alta calidad metodológica que permitan definir los programas más apropiados para la aplicación terapéutica.

    Retinal pigment epithelium degeneration caused by aggregation of PRPF31 and the role of HSP70 family of proteins

    Get PDF
    Background Mutations in pre-mRNA splicing factor PRPF31 can lead to retinitis pigmentosa (RP). Although the exact disease mechanism remains unknown, it has been hypothesized that haploinsufficiency might be involved in the pathophysiology of the disease. Methods In this study, we have analyzed a mouse model containing the p.A216P mutation in Prpf31 gene. Results We found that mutant Prpf31 protein produces cytoplasmic aggregates in the retinal pigment epithelium and decreasing the protein levels of this splicing factor in the nucleus. Additionally, normal protein was recruited in insoluble aggregates when the mutant protein was overexpressed in vitro. In response to protein aggregation, Hspa4l is overexpressed. This member of the HSP70 family of chaperones might contribute to the correct folding and solubilization of the mutant protein, allowing its translocation to the nucleus. Conclusions Our data suggests that a mechanism haploinsufficiency and dominant-negative is involved in retinal degeneration due to mutations in PRPF31. HSP70 over-expression might be a new therapeutic target for the treatment of retinal degeneration due to PRPF31 mutations.This project has been financed through a) The ISCIII (Miguel Servet-I, 2015), co-financed by the European Regional Development Fund (ERDF), No CP15/00071. b) The European Union’s Horizon 2020 research and innovation program, under grant agreement No 634479. c) Regional Ministry of Economy, Innovation and Science of the Junta de Andalucía, No P09-CTS-04967.info:eu-repo/semantics/publishedVersio
