FloraSNevada: a trait database of the vascular flora of Sierra Nevada, southeast Spain

The complete data sets corresponding to abstracts published in theData Papers section in the journal are published electronically asSupportingInformationintheonlineversionofthisarticleat http://onlinelibrary.wiley.com/doi/10.1002/ecy.3091/suppinfoAssociated data are also available at PANGAEA: https://doi.org/10.1594/PANGAEA.910792Providing a complete data set with species and trait information for a given area is essential for assessing plant conservation, management, and ecological restoration, for both local and global applications. Also, these data sets provide additional information for surveys or data collections, establishing the starting point for more detailed studies on plant evolution, vegetation dynamics, and vegetation responses to disturbance and management. This data base covers Sierra Nevada mountains (southeastern Spain), a recognized plant biodiversity hotspot within the Mediterranean context. According to previous available data (before this augmented compilation), these mountains host 7% of the 24,000 Mediterranean vascular plants, despite covering just 0.01% of its area. Another characteristic of the Sierra Nevada is the great singularity of its flora, with 95 taxa being endemic to the high-mountain area of Sierra Nevada and surroundings. From these endemic taxa, 70% are endangered by different threats, global warming being a leading cause. We seek to provide a complete and updated database of the flora of the Sierra Nevada mountains (southeast Spain). The goal of the present data set is to compile the names of all the vascular plant taxa inhabiting Sierra Nevada, together with relevant features including taxonomical, morphological-ecological traits, distribution, habitats, abundance, and conservation status. The data were compiled according to all the available information sources on taxonomy, ecology, and plant-species distribution. The resulting data set includes 2,348 taxa belonging to 1,937 species, 377 subspecies, and 34 hybrids, from a total of 756 genera and 146 families represented in the collection. For each taxa, together with taxonomical information (Phylum, Class, Family, Genus, Taxa), we compiled plant traits (life form, spinescence, flower symmetry, flower sexuality, plant gender, androecium:ginoecium ratio, flower color, perianth type, pollinator type, flowering, seed dispersal, and vegetative reproduction), and their environmental association (origin, endemic character, general distribution, substrate, elevation, habitat, local abundance, hygrophilous behavior, and conservation status). All these traits were compiled from all the available information sources, resulting in a complete and updated database for Sierra Nevada vascular flora. This data set provides valuable information on plant traits in an outstanding micro hotspot within the Mediterranean hotspot. This data set can be freely used for non commercial purposes

A nationwide study of chronic pain prevalence in the general Spanish population, identifying clinical subgroups through cluster analysis.

Objective. This study aims to assess the prevalence of chronic pain, its characteristics, and its impact on the general Spanish population. Also, to establish chronic pain patient subgroups according to the characteristics of pain and to identify variables specifically associated with each subgroup. Design. Telephone-based, cross-sectional nationwide study. Subjects. A sample of 1,957 individuals representative of the Spanish population. Methods. Data were collected through telephone interviews. A subject was considered to have chronic pain if they had suffered pain (at least 4 days a week) during the last 3 months. The subjects were divided into two subgroups through a cluster analysis, and a regression model was established to determine the variables most specifically associated with these subgroups. Results. The prevalence of chronic pain was 16.6% (95% confidence interval: 14.9–18.3) and among these subjects, more than 50% referred to limitations in their daily activities, 30% felt sad and/or anxious, and 47.2% indicated that their pain was affecting their family life. Two subgroups of subjects with pain were identified: 1) characterized by generalized pain in more than one location and of a long evolution (150 months); and 2) characterized by pain localized to only one site with a shorter duration (100 months). Individuals who felt anxious because of their pain and those who considered that their pain was affecting their family were more likely to belong to group 1. Conclusions. Pain affects an important proportion of the Spanish adult population and that it has a strong personal impact. Two pain groups were clearly distinguished by their clinical characteristics

Consideraciones de la ventilación mecánica invasiva en posición prona. Revisión narrativa

Sintetizamos la evidencia con respecto a las consideraciones logísticas y los eventos de seguridad asociados a la ventilación mecánica en posición prona (VMPP) y proponemos un flujograma para realizarla de manera segura en el escenario de la pandemia por COVID-19. Para ello, realizamos una búsqueda de la literatura en las bases de datos Medline vía PubMed, Embase, Lilacs, Cochrane Database of Systematic Reviews, Cochrane Central Register of Randomized Controlled Trials, Cochrane Database of Abstracts of Reviews of Effects, ProQuest Nursing and Allied Health Database y Google académico. Se incluyeron 31 artículos para ser analizados. La incidencia de even-tos de seguridad relacionados a la VMPP varía entre 1 % a 11.9 %, las complicaciones más frecuentes son las úlceras por presión y de la vía aérea. Se recomienda iniciar nutrición enteral temprana y es posible realizar traslado de pacientes con VMPP. Existe controversia acerca de las contraindicaciones y recomendaciones de la VMPP. Las recomendaciones para realizarla de forma segura se basan en opi-niones de expertos y en la instauración de protocolos para el entrenamiento del personal de salud. Se requieren estudios clínicos para determinar cuáles recomendaciones son necesarias para que la VMPP se realice de forma segura y reproducible durante esta pandemiaThe evidence regarding logistic considerations and safety events associated with prone position ventilation (PPV) is summarized and a flow diagrama for safe provision of mechanical ventilation in the setting of the COVID-19 pandemic is proposed. A review of the literature was conducted in the Medline via Pubmed, Embase, and Lilacs databases, the Cochrane Database of Systematic Reviews, Cochrane Central Register of Randomized Controlled Trials, Cochrane Database of Abstracts of Reviews of Effects, ProQuest Nursing and Allied Health Database, and Google scholar. Overall, 31 articles were selected for the analysis. The incidence of PPV-related safety events varies between 1% and 11.9% and the most frequent complications are pressure ulcers and airway complications. Early initiation of enteral nutrition is recommended, and transfers are possible in patients on PPV. There is controversy regarding contraindications and recommendations for PPV. Recommendations for its safe provision are based on expert opinions and the establishment of protocols for healthcare staff training. Clinical studies are required to determine which are the recommendations that should be considered for safe and reproducible PPV use during this pandemic.https://orcid.org/0000-0003-3863-8993Revista Nacional - Indexad

Virus en Endodoncia

La infección endodóntica es la infección que afecta al sistema de conductos radiculares y, sin duda, es el principal agente etiológico de las periodontitis apicales. Además, de las bacterias patógenas endodónticas, se ha buscado en los últimos años asociar la presencia de virus en distintos tipos de patología endodóntica. Los virus que más se han buscado y asociado son los pertenecientes a la familia herpesvirus, los cuales se han encontrado presentes en patologías periapicales principalmente. Se ha buscado además, relacionar su presencia a patologías que cursan con mayor sintomatología, o que presentan a la imagen radiográfica destrucciones óseas periapicales mayores. El rol de los virus en las lesiones apicales de origen endodóntico está aún poco claro, se habla de efectos acumulativos a los de las bacterias, además de posibles inmunosupresiones locales que favorecerían el crecimiento y el efecto de estas última

Molecular epidemiology of Giardia, Blastocystis and Cryptosporidium among Indigenous children from the Colombian Amazon basin

The incidence and prevalence of intestinal parasites in children is most likely due to lack of natural or acquired resistance and differences in behavior and habits closely related to environmental and socioeconomic determinants. The most important protozoa that parasitize humans are Giardia, Entamoeba, Blastocystis, and Cryptosporidium. These parasites present wide intraspecific genetic diversity and subsequently classified into assemblages and subtypes. The Amazon basin is the largest in the world and is the fifth freshwater reserve on the planet. Contradictorily, people living in these areas (Indigenous populations) have poor quality of life, which favors the infection of diseases of fecal-oral transmission. The aim of this work was to unravel the molecular epidemiology of Giardia, Blastocystis and Cryptosporidium across four communities (Puerto Nariño, San Juan del Soco, Villa Andrea and Nuevo Paraíso). We obtained 284 fecal samples from children under 15 years old that were analyzed by direct microscopy (261 samples) and Real Time PCR (qPCR) (284 samples). The positive samples for these protozoa were further characterized by several molecular markers to depict assemblages and subtypes. We observed a frequency of Giardia infection by microscopy of 23.7% (62 samples) and by qPCR of 64.8% (184 samples); for Blastocystis by microscopy of 35.2% (92 samples) and by qPCR of 88.7% (252 samples) and for Cryptosporidium only 1.9% (5 samples) were positive by microscopy and qPCR 1.8% (5 samples). Regarding the Giardia assemblages, using the glutamate dehydrogenase (gdh) marker we observed AI, BIII and BIV assemblages and when using triose phosphate isomerase (tpi) we observed assemblages AI, AII, BIII and BIV. In contrast, Blastocystis STs detected were 1, 2, 3, 4, and 6. Lastly, the species C. viatorum, C. hominis (with the subtypes IdA19 and IaA12R8) and C. parvum (with the subtype IIcA5G3c) were identified. We observed a high profile of zoonotic transmission regarding the Giardia assemblages and Blastocystis STs/alleles. Also, we highlight the elevated frequency of infection by these two protozoans suggesting an active transmission in the area. Our findings reinforces the need to deploy better epidemiological surveillance systems for enteric pathogens in the area. © 2017 Sánchez, Munoz, Gómez, Tabares, Segura, Salazar, Restrepo, Ruíz, Reyes, Qian, Xiao, López and Ramírez

RegulonDB (version 5.0): Escherichia coli K-12 transcriptional regulatory network, operon organization, and growth conditions

RegulonDB is the internationally recognized reference database of Escherichia coli K-12 offering curated knowledge of the regulatory network and operon organization. It is currently the largest electronically-encoded database of the regulatory network of any free-living organism. We present here the recently launched RegulonDB version 5.0 radically different in content, interface design and capabilities. Continuous curation of original scientific literature provides the evidence behind every single object and feature. This knowledge is complemented with comprehensive computational predictions across the complete genome. Literature-based and predicted data are clearly distinguished in the database. Starting with this version, RegulonDB public releases are synchronized with those of EcoCyc since our curation supports both databases. The complex biology of regulation is simplified in a navigation scheme based on three major streams: genes, operons and regulons. Regulatory knowledge is directly available in every navigation step. Displays combine graphic and textual information and are organized allowing different levels of detail and biological context. This knowledge is the backbone of an integrated system for the graphic display of the network, graphic and tabular microarray comparisons with curated and predicted objects, as well as predictions across bacterial genomes, and predicted networks of functionally related gene products.

Ocular Involvement in Friedreich Ataxia Patients and its Relationship with Neurological Disability, a Follow-up Study

Background: This study compared functional and structural visual changes in Friedreich ataxia (FRDA) patients with healthy controls (HC) and correlated these changes with neurological disability. Methods: Eight FRDA Spanish patients and eight HC were selected from 2014 to 2018. Best corrected visual acuity (BCVA), visual field (VF), optic coherence tomography (OCT), and neurological disability measured by “scale for the assessment and rating of ataxia” (SARA) were taken in a basal exploration and repeated after 6 months. A linear mixed analysis and Bonferroni p-value correction were performed. Results: FRDA baseline and follow-up patients showed statistically significant decreases in BCVA, VF, and OCT parameters compared with the HC. Some of the VF measurements and most of the OCT parameters had an inverse mild-to-strong correlation with SARA. Moreover, the analysis of the ROC curve demonstrated that the peripapillary retinal nerve fiber layer (pRNFL) average thickness was the best parameter to discriminate between FRDA patients and HC. Conclusions: The follow-up study showed a progression in OCT parameters. Findings showed a sequential effect in pRNFL, ganglion cell complex (GCC), and macula. The VF and the OCT could be useful biomarkers in FRDA, both for their correlation with neurological disease as well as for their ability to evaluate disease progression

Perfiles de poliparasitismo intestinal en una comunidad de la Amazonia colombiana

Introduction: Intestinal parasite infections and polyparasitism are highly prevalent in the most vulnerable populations of developing countries due to environmental, biological and social determinants common in the transmission of parasites. Children between 1 and 15 years of age are the most affected population.Objective: To describe the prevalence and profiles of intestinal polyparasitism in 1 to 15 year-old children from native communities in the Colombian Amazon region.Materials and methods: We used a non-probability sampling of 300 children between 1 and 15 years of age from several rural settlements and the main urban area of Puerto Nariño, Amazonas, Colombia, who participated voluntarily in the study. We obtained fecal samples that were analyzed by the direct method (0.85% saline solution-lugol) and the Kato-Katz technique. The most prevalent polyparasitism profiles were identified using Cohen’s kappa coefficient with a 95% confidence interval.Results: The prevalence of polyparasitism, defined as the presence of at least two intestinal pathogenic parasites, was 84% (95 % CI: 79.35-87.96). Polyparasitism by two or three of the following parasites: Ascaris lumbricoides, Trichuris trichiura, Blastocystis sp., Ancylostoma duodenale and Necator americanus from the Ancylostomatidae family, and Entamoeba histolytica, E. dispar and E. moshkovskii of the Entamoeba complex, had the highest prevalence.Conclusion: Several intestinal polyparasitism profiles were found, although in most cases fewer than six parasites were involved. Better prevalence estimations and identification of determinant factors will allow to priorize and direct resources to control these infections.Introducción. Las infecciones parasitarias y el poliparasitismo intestinal son muy prevalentes en las poblaciones más vulnerables de los países en desarrollo debido a la existencia de factores ambientales, biológicos y sociales determinantes en la transmisión de parásitos. La población entre uno y 15 años de edad es la más afectada por dicha situación.Objetivo. Describir las prevalencias y los perfiles del poliparasitismo intestinal en la población de uno a 15 años de edad de comunidades indígenas de la Amazonia colombiana.Materiales y métodos. Se hizo un muestreo no probabilístico de 300 niños entre uno y 15 años de edad, procedentes de varios asentamientos rurales y de la cabecera urbana de Puerto Nariño, Amazonas, quienes participaron voluntariamente en el estudio. Las muestras de materia fecal se analizaron mediante el método directo (solución salina al 0,85 % y lugol) y la técnica de Kato-Katz. Se determinaron los perfiles más prevalentes de poliparasitismo intestinal con el coeficiente kappa de Cohen y un intervalo de confianza de 95 %.Resultados. La prevalencia de poliparasitismo, definida como la presencia de, por lo menos, dos parásitos intestinales patógenos, fue de 84 % (IC95 %: 79,35-87,96). Los casos con presencia de dos o tres agentes incluyeron los parásitos Ascaris lumbricoides, Trichuris trichiura, Blastocystis sp., los ancilostomídeos Ancylostoma duodenale y Necator americanus, así como Entamoeba histolytica, E. dispar y E. moshkovskii del complejo Entamoeba, y fueron los de mayor prevalencia.Conclusión. Se encontraron varios perfiles de poliparasitismo intestinal, aunque la mayoría de los casos involucraron menos de seis especies. Una mejor estimación de la prevalencia y los factores determinantes del poliparasitismo intestinal permitirían priorizar y orientar los recursos para su control

Changes in Retinal OCT and Their Correlations with Neurological Disability in Early ALS Patients, a Follow-Up Study

Background: To compare early visual changes in amyotrophic lateral sclerosis (ALS) patients with healthy controls in a baseline exploration, to follow-up the patients after 6 months, and to correlate these visual changes with neurological disability. Methods: All patients underwent a comprehensive neurological and ophthalmological examination. A linear mixed analysis and Bonferroni p-value correction were performed, testing four comparisons as follows: Control baseline vs. control follow-up, control baseline vs. ALS baseline, control follow-up vs. ALS follow-up, and ALS baseline vs. ALS follow-up. Results: The mean time from the diagnosis was 10.80 ± 5.5 months. The analysis of the optical coherence tomography (OCT) showed: (1) In ALS baseline vs. control baseline, a macular significantly increased thickness of the inner macular ring temporal and inferior areas; (2) in ALS follow-up vs. ALS baseline, a significant macular thinning in the inner and outer macular ring inferior areas; (3) in ALS follow-up vs. ALS baseline, a significant peripapillary retinal nerve fiber layer (pRNFL) thinning in the superior and inferior quadrants; and (4) ALS patients showed a moderate correlation between some OCT pRNFL parameters and Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R) score. Conclusion: The OCT showed retinal changes in patients with motoneuron disease and could serve as a complementary tool for studying ALS

Obstructive Sleep Apnea (OSA) and its relation with perioperative complications : literature review

El objetivo de este artículo es revisar la importancia del síndrome de apnea-hipopnea obstructiva del sueño (SAHOS) en la población que va a ser llevada a cirugía y cómo detectar en el preoperatorio a pacientes con riesgo elevado de complicaciones en el perioperatorio mediante el cuestionario STOP-BANG. Para lo anterior, se realizó una búsqueda en las bases Pubmed, Science y SciELO. El SAHOS es un problema médico importante con prevalencia variable (hasta el 26 % en la población general dependiendo del centro donde se evalúe). Es una enfermedad de inicio insidioso y progresivo, en la que hay episodios recurrentes de apneas o hipopneas causadas por obstrucción de la vía aérea superior durante el sueño que produce un deterioro significativo de la calidad de vida. Se quiere evaluar si el cuestionario STOP-BANG es útil para identificar, en el preoperatorio, a pacientes que tengan complicaciones perioperatorias, probablemente porque identifica pacientes con SAHOS no diagnosticado.Artículo de revisión407-423The aim of this article is to make a literature review of the importance of Obstructive Sleep Apnea-Hypopnea Syndrome (OSA) in the population that will be taken to surgery and how to detect preoperatively patients at high risk for perioperative complications by the STOP-BANG questionnaire. Thus, we performed a search in PubMed, Science and SciELO databases. OSA is a major medical problem with variable prevalence (up to 26 % in the general population depending on the centre where they are evaluated). It is a disease with an insidious and progressive onset, in which there are recurrent episodes of apneas or hypopneas caused by obstruction of the upper airway during sleep, resulting in a significant impairment of quality of life. Therefore, we want to assess whether this instrument can be used to identify, preoperatively, patients who have perioperative complications, probably because it identifies patients with undiagnosed OSA
