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

A review of chronic pain impact on patients, their social environment and the healthcare system.
Abstract: Chronic pain (CP) seriously affects the patient’s daily activities and quality of life, but few studies on CP have considered its effects on the patient’s social and family environ ment. In this work, through a review of the literature, we assessed several aspects of how CP influences the patient’s daily activities and quality of life, as well as its repercussions in the workplace, and on the family and social environment. Finally, the consequences of pain on the health care system are discussed. On the basis of the results, we concluded that in addition to the serious consequences on the patient’s life, CP has a severe detrimental effect on their social and family environment, as well as on health care services. Thus, we want to emphasize on the need to adopt a multidisciplinary approach to treatment so as to obtain more comprehensive improvements for patients in familial and social contexts. Accordingly, it would be beneficial to promote more social- and family-oriented research initiatives
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
The Impact of Chronic Pain: the Perspective of Patients, Relatives and Caregivers
Objective. To assess the impact of chronic pain on the family environment from the
patient’s, relative’s and caregiver’s perspective.
Methods. A cross-sectional study on a representative sample of Spanish adults that suffered pain at least 4 days a week for ≥3 months, and on relatives and caregivers of patients that fulfilled these criteria. The characteristics of pain and the perception of its impact on the family environment was assessed, using logistic regression models to reveal the variables associated with the impact of pain on the family.
Results. From a total of 1,957 subjects, 325 suffered chronic pain and 34.6% of them
perceived that their pain affected their family environment. These patients recognized a stronger impact when their relatives were sad (OR=3.61; CI:1.57, 8.27) and had modified the leisure activities because of the pain (OR=3.62; CI:1.56, 8.38). Among the 131 relatives, 51.2% perceived that pain was affecting the family, causing changes in their leisure activities (OR=1.17; CI:1.04, 9.94) and sleep disturbance (OR=1.40; CI:1.32, 12.58). Of the 36 caregivers, mainly women over 50 years of age, 66.7% indicated that pain affected the family, although 72.8% were satisfied with the help they provided.
Conclusion. Chronic pain has a very strong impact on the family, although this is perceived distinctly by patients, relatives and caregivers. Recognising that factors related to pain affect the family’s well-being, and adopting a global approach to pain that takes into consideration the family’s experiences, should improve the therapeutic response, and enhance the patient’s and relative’s quality of life
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
