Marine oomycetes of the genus halophytophthora harbor viruses related to bunyaviruses

We investigated the incidence of RNA viruses in a collection of Halophytophthora spp. from estuarine ecosystems in southern Portugal. The first approach to detect the presence of viruses was based on the occurrence of dsRNA, typically considered as a viral molecule in plants and fungi. Two dsRNA-banding patterns (∼7 and 9 kb) were observed in seven of 73 Halophytophthora isolates tested (9.6%). Consequently, two dsRNA-hosting isolates were chosen to perform stranded RNA sequencing for de novo virus sequence assembly. A total of eight putative novel virus species with genomic affinities to members of the order Bunyavirales were detected and their full-length RdRp gene characterized by RACE. Based on the direct partial amplification of their RdRp gene by RT-PCR multiple viral infections occur in both isolates selected. Likewise, the screening of those viruses in the whole collection of Halophytophthora isolates showed that their occurrence is limited to one single Halophytophthora species. To our knowledge, this is the first report demonstrating the presence of negative (-) ssRNA viruses in marine oomycetes.Project Phytophthora Research Centre CZ.02.1.01/0.0/0.0/15_003/0000453info:eu-repo/semantics/publishedVersio

Mutation affecting the proximal promoter of Endoglin as the origin of hereditary hemorrhagic telangiectasia type 1

[Background] Hereditary hemorrhagic telangiectasia (HHT) is a vascular multi-organ system disorder. Its diagnostic criteria include epistaxis, telangiectases in mucocutaneous sites, arteriovenous malformations (AVMs), and familial inheritance. HHT is transmitted as an autosomal dominant condition, caused in 85% of cases by mutations in either Endoglin (ENG) or Activin receptor-like kinase (ACVRL1/ACVRL1/ALK1) genes. Pathogenic mutations have been described in exons, splice junctions and, in a few cases with ENG mutations, in the proximal promoter, which creates a new ATG start site. However, no mutations affecting transcription regulation have been described to date in HHT, and this type of mutation is rarely identified in the literature on rare diseases.[Methods] Sequencing data from a family with HHT lead to single nucleotide change, c.-58G > A. The functionality and pathogenicity of this change was analyzed by in vitro mutagenesis, quantitative PCR and Gel shift assay. Student t test was used for statistical significance.[Results] A single nucleotide change, c.-58G > A, in the proximal ENG promoter co-segregated with HHT clinical features in an HHT family. This mutation was present in the proband and in 2 other symptomatic members, whereas 2 asymptomatic relatives did not harbor the mutation. Analysis of RNA from activated monocytes from the probands and the healthy brother revealed reduced ENG mRNA expression in the HHT patient (p = 0.005). Site-directed mutagenesis of the ENG promoter resulted in a three-fold decrease in luciferase activity of the mutant c.-58A allele compared to wild type (p = 0.005). Finally, gel shift assay identified a DNA-protein specific complex.[Conclusions] The novel ENG c.-58G > A substitution in the ENG promoter co-segregates with HHT symptoms in a family and appears to affect the transcriptional regulation of the gene, resulting in reduced ENG expression. ENG c.-58G > A may therefore be a pathogenic HHT mutation leading to haploinsufficiency of Endoglin and HHT symptoms. To the best of our knowledge, this is the first report of a pathogenic mutation in HHT involving the binding site for a transcription factor in the promoter of ENG.This study has been supported by grants from Ministerio de Economia y Competitividad of Spain (SAF2011-23475 and SAF2014-52374-R) to L.M.

Reporting Quality in Abstracts of Randomized Controlled Trials Published in High-Impact Occupational Therapy Journals

Importance: Adequate reporting in the abstracts of randomized controlled trials (RCTs) is essential to enable occupational therapy practitioners to critically appraise the validity of findings. Objective: To evaluate the reporting quality and characteristics of RCT abstracts published between 2008 and 2018 in the occupational therapy journals with the five highest impact factors in 2018. Design: A descriptive cross-sectional study. Data sources: The American Journal of Occupational Therapy (AJOT), Australian Occupational Therapy Journal (AOTJ), Canadian Journal of Occupational Therapy (CJOT), Scandinavian Journal of Occupational Therapy (SJOT), and Physical and Occupational Therapy in Pediatrics (POTP) were identified using a Web of Science search. Study selection and data collection: We searched Scopus for abstracts in the five included journals. We used a 17-point scale based on the CONSORT for Abstracts (CONSORT-A) checklist to assess reporting quality. We also identified characteristics of the abstracts. Findings: Seventy-eight RCT abstracts were assessed and showed moderate to low adherence to the CONSORT-A checklist (Mdn = 8, interquartile range = 7-9). Abstracts of articles with authors from a higher number of institutions, European first authors, and >200 words had higher CONSORT-A scores. The most underreported CONSORT-A items were trial design, blinding, numbers analyzed, outcome (results), harms, trial registration, and funding. Conclusions and relevance: Between 2008 and 2018, the reporting quality in RCT abstracts from the five highest impact occupational therapy journals was moderate to low. Inadequate reporting in RCT abstracts raises the risk that occupational therapy practitioners will make ineffective clinical decisions based on misinterpretation of findings. What This Article Adds: Reporting quality in RCT abstracts in occupational therapy journals is moderate to low. Journal editors should require authors of RCTs to use the CONSORT-A checklist to promote optimal reporting and transparency in abstract

At the beginnings of the funerary Megalithism in Iberia at Campo de Hockey necropolis

[EN] The excavations undertaken at the Campo de Hockey site in 2008 led to the identification of a major Neolithic necropolis in the former Island of San Fernando (Bay of Cadiz). This work presents the results of the latest studies, which indicate that the site stands as one of the oldest megalithic necropolises in the Iberian Peninsula. The main aim of this work is to present with precision the chronology of this necropolis through a Bayesian statistical model that confirms that the necropolis was in use from c. 4300 to 3800 cal BC. The presence of prestige grave goods in the earliest and most monumental graves suggest that the Megalithism phenomenon emerged in relation to maritime routes linked to the distribution of exotic products. We also aim to examine funerary practices in these early megalithic communities, and especially their way of life and the social reproduction system. As such, in addition to the chronological information and the Bayesian statistics, we provide the results of a comprehensive interdisciplinary study, including anthropological, archaeometric and genetic data.We wish to express our gratitude to Antonio Saez Espligares (Historical Museum of San Fernando) and Lourdes Lorenzo (Figlina, s.l.) for their support during the archaeological excavation.

Proyecto HAD 2020: una propuesta para consolidar la hospitalización a domicilio en España

Hospital at home (HAH) appeared in Spain 36 years ago with the opening of several units. The initial push was truncated by the lack of political leadership and sometimes clinical as well. The current reality offers an irregular implementation with a wide disparity of assistance and resource models. The Sociedad Española de Hospitalización a Domicilio (SEHAD) has not played either the expected scientific or professional leadership roles. The “Plan HAD2020: key of the future” was designed as revulsive. This is an ambitious 4-year project to consolidate HAH as a care modality. Its deployment consists of five phases. Preparation: the foundations of the strategic plan (EP) were established. Situation analysis: a national survey was carried out on the 106 operational units (data 2014). Validation of the EP: contributions and proposals of action of the members of SEHAD. National Congress 2016: presentation and approval of EP conclusions and proposals. EP deployment phase: it will be extended until 2020 and will be executed by various teams of referents spread over five lines of work.The final objective set for the year 2020 is: to come up with a more homogenous care model; to promote the training and professional recognition of those who work in the HAD; that each hospital in Spain has a HAH unit; recognition and empowerment by the national health system.HAD2020 has marked an inflection point in the SEHAD. The traced path and the effort of all the HAH professionals will allow reaching the vision which the pioneers of the HAH in Spain pursued.La Hospitalización a Domicilio (HAD) apareció en España hace 36 años con la apertura de diversas unidades. El empuje inicial fue truncado por la falta de liderazgo político y en ocasiones también clínico. La realidad actual ofrece una implantación irregular con disparidad de modelos asistenciales y de recursos. La Sociedad Española de Hospitalización a Domicilio (SEHAD) no ha jugado el papel de liderazgo científico y profesional esperado. Se diseñó el «Plan HAD2020: clave de futuro» como revulsivo. Se trata de un ambicioso proyecto a 4 años para consolidar la HAD como modalidad asistencial. Su despliegue consta de cinco fases. Preparación: se establecieron las bases del plan estratégico (PE). Análisis de situación: se realizó una encuesta nacional a las 106 unidades operativas (datos 2014). Validación del PE: aportaciones y propuestas de actuación de los miembros de SEHAD. Congreso Nacional 2016: presentación y aprobación de conclusiones y propuestas del PE. Fase de despliegue PE: se extenderá hasta el año 2020 y la ejecutarán diversos equipos referentes, repartidos en cinco líneas de trabajo.El objetivo final fijado para el año 2020 consiste en: consensuar un modelo asistencial más homogéneo; promover la formación y reconocimiento profesional de quienes trabajan en la HAD; que cada hospital de España tenga una unidad de HAD; reconocimiento y potenciación por el sistema de salud nacional.HAD2020 ha marcado un punto de inflexión en la SEHAD. El camino trazado y el esfuerzo de todos los profesionales HAD permitirán alcanzar aquella visión que persiguieron los pioneros de la HAD en España
