Endless forms most frustrating: disentangling species boundaries in the Ramalina decipiens group (Lecanoromycetes, Ascomycota), with the description of six new species and a key to the group.

Oceanic islands have been recognized as natural laboratories in which to study a great variety of evolutionary processes. One such process is evolutionary radiations, the diversification of a single ancestor into a number of species that inhabit different environments and differ in the traits that allow them to exploit those environments. The factors that drive evolutionary radiations have been studied for decades in charismatic organisms such as birds or lizards, but are lacking in lichen-forming fungi, despite recent reports of some lineages showing diversification patterns congruent with radiation. Here we propose the Ramalina decipiens group as a model system in which to carry out such studies. This group is currently thought to be comprised of five saxicolous species, all of them endemic to the Macaronesian region (the Azores, Madeira, Selvagens, Canary and Cape Verde islands). Three species are single-island endemics (a rare geographic distribution pattern in lichens), whereas two are widespread and show extreme morphological variation. The latter are suspected to harbor unrecognized species-level lineages. In order to use the Ramalina decipiens group as a model system it is necessary to resolve the group's phylogeny and to clarify its species boundaries. In this study we attempt to do so following an integrative taxonomy approach. We constructed a phylogenetic tree based on six molecular markers, four of which are newly developed and generated competing species hypotheses based on molecular (species discovery strategies based on both single locus and multilocus datasets) and phenotypic data (unsupervised clustering algorithms based on morphology, secondary chemistry and geographic origin). We found that taxonomic diversity in the Ramalina decipiens group has been highly underestimated in previous studies. In consequence, we describe six new species, most of them single-island endemics and provide a key to the group. Phylogenetic relationships among species have been reconstructed with almost full support which, coupled with the endemic character of the group, makes it an excellent system for the study of island radiations in lichen-forming fungi.

Metabolic and physiological adaptations of microalgal growth-promoting bacterium Azospirillum brasilense growing under biogas atmosphere: a microarray-based transcriptome analysis.

Using microalgal growth-promoting bacteria (MGPB) to improve the cultured microalga metabolism during biotechnological processes is one of the most promising strategies to enhance their benefits. Nonetheless, the culture condition effect used during the biotechnological process on MGPB growth and metabolism is key to ensure the expected positive bacterium growth and metabolism of microalgae. In this sense, the present research study investigated the effect of the synthetic biogas atmosphere (75% CH4-25% CO2) on metabolic and physiological adaptations of the MGPB Azospirillum brasilense by a microarray-based transcriptome approach. A total of 394 A. brasilense differentially expressed genes (DEGs) were found: 201 DEGs (34 upregulated and 167 downregulated) at 24 h and 193 DEGs (140 upregulated and 53 downregulated) under the same conditions at 72 h. The results showed a series of A. brasilense genes regulating processes that could be essential for its adaptation to the early stressful condition generated by biogas. Evidence of energy production is shown by nitrate/nitrite reduction and activation of the hypothetical first steps of hydrogenotrophic methanogenesis; signal molecule modulation is observed: indole-3-acetic acid (IAA), riboflavin, and vitamin B6, activation of Type VI secretion system responding to IAA exposure, as well as polyhydroxybutyrate (PHB) biosynthesis and accumulation. Moreover, an overexpression of ipdC, ribB, and phaC genes, encoding the key enzymes for the production of the signal molecule IAA, vitamin riboflavin, and PHB production of 2, 1.5 and 11 folds, respectively, was observed at the first 24 h of incubation under biogas atmosphere Overall, the ability of A. brasilense to metabolically adapt to a biogas atmosphere is demonstrated, which allows its implementation for generating biogas with high calorific values and the use of renewable energies through microalga biotechnologies.

Diagnostic accuracy of the Spanish version of the 4AT scale (4AT-ES) for delirium screening in older inpatients

Background and objectivesThe 4AT scale is a sensitive tool for screening delirium, which can be applied rapidly in clinical settings without any specific training. It has not been translated, adapted, and validated to assess Spanish older adults. The aims of the study are: to translate and adapt to Spanish culture the 4AT scale, to present evidence of the diagnostic accuracy of this version (4AT-ES) when applied in non-specialized hospital wards, and to assess the loss of diagnostic accuracy in presence of risk factors.MethodsA prospective sample was independently assessed on the 4AT-ES and the reference standard. One hundred and twenty-one inpatients (70+ years) for whom a psychiatric assessment was requested were included. Out of them, 50 were diagnosed with delirium. Nurses without specific training applied the 4AT-ES, and experienced psychiatrists cast the reference standard diagnosis (DSM-V criteria).ResultsPatients with delirium were older and had more risk factors (more previous delirium episodes, a higher likelihood of prior dementia/cognitive impairment) than controls. The 4AT-ES had excellent validity, sensitivity (96%) , and specificity (83.1%). The area under the curve was 0.918; in the subsample with any of those risk factors, its value did not decrease.ConclusionThe 4AT-ES version of the 4AT scale was developed. When applied by non-specifically trained, nursing staff it showed excellent validity, sensitivity, and specificity, even in a subsample with previous risk factors. All indices were comparable to the original version. We recommend its use for efficient delirium screening in hospitalized older patients with suspected delirium. (AU)

Antibacterial effect of acetic acid during an outbreak of carbapenem-resistant Acinetobacter baumannii in an ICU (II).

INTRODUCTION: Acetic acid (AA) has been commonly used in medicine as an antiseptic agent for the past 6000 years. This study evaluated the antibacterial effect of AA during an outbreak in an intensive care unit (ICU) facility in Baja California Sur, México. METHODOLOGY: Thirty-five environmental samples were collected, subsequently, disinfection with AA (4%) was performed, and two days later the same areas were sampled inside the ICU facility. Carbapenem-resistant A. baumannii (CRAB) was detected with loop-mediated isothermal amplification assay (Garciglia-Mercado et al. companion paper), targeting blaOXA-23-like, blaOXA-24-like, blaOXA-51-like, blaOXA-58-like, blaIMP and blaVIM genes. CRAB isolates before and after disinfection were compared by PFGE. RESULTS: Eighteen (54.5%) and five (14.3%) of thirty-five environmental samples were identified as Acinetobacter baumannii before and after disinfection, respectively, showing a significant decrease of 85.7% (p < 0.05) both by Loop-mediated isothermal amplification (LAMP) and polymerase chain reaction (PCR). Furthermore, the presence of blaOXA-23-like and blaOXA-58-like genes significantly decreased (p < 0.05) both by LAMP and PCR methods. PFGE genotype showed high similarity among CRAB isolates before and after disinfection, suggesting wide clonal dissemination in the ICU facility. CONCLUSIONS: This study demonstrated the novel application of AA with the LAMP assays developed for detecting CRAB. AA promises to be a cheap and efficacious disinfectant alternative to both developed and especially developing countries, preventing the spread of this organism in the environment and to other susceptible patients in health care settings.

Mercury in sediment cores from the southern Gulf of Mexico: Preindustrial levels and temporal enrichment trends.

Spatial and temporal variability of mercury concentrations in sediments was evaluated in 210Pb-dated sediment cores from offshore and intertidal areas in the southern Gulf of Mexico. In offshore cores, mercury concentrations were comparable (11.2-69.2 ng g-1), and intermediate between concentrations in intertidal cores from the eastern (6.0-34.4 ng g-1) and the western (34.9-137.7 ng g-1) inlets of Términos Lagoon. The enrichment factor (EF) indicated minimal contamination (EF < 2) in most offshore cores, whereas in some intertidal cores steadily increasing mercury enrichment and fluxes were observed along the past century. No evidence of oil industry related mercury contamination was found, as the minor but increasing enrichment in intertidal cores is most likely related to land-derived sources such as catchment eroded soils and waste water runoff. Results highlight the importance to control catchment erosion and untreated sewage releases to reduce mercury loadings to the coastal zone.

Natural and anthropogenic oil impacts on benthic foraminifera in the southern Gulf of Mexico.

The Campeche Sound is the major offshore oil producing area in the Southern Gulf of Mexico (SGoM). To evaluate the impact of oil related activities in the ocean floor sediments, we analyzed the geochemical (major and trace element, organic carbon and hydrocarbon concentrations) and biological (benthic foraminifera) composition of 62 superficial sediment samples, from 13 to 1336 m water depth. Cluster and Factor analysis of all the variables indicate that their distribution patterns are mainly controlled by differences between the terrigenous and carbonate platforms in the SGoM. Benthic foraminiferal assemblages were abundant and diverse, and their distribution patterns are mainly determined by water depth and sedimentary environment. However, most of the abundant species are opportunistic and/or low-oxygen tolerant, and many of their tests show oil stains and infillings, characteristic of oil polluted locations, suggesting the environment has been modified by natural seepage or oil-related activities. To determine if these conditions are natural or anthropogenic in origin, pre - industrial settings should be studied. Organic carbon (Corg) content (0.6-2.9%) and total hydrocarbon concentrations (PAHs 1.0-29.5 µg kg-1) were usually higher around the oil platforms area, the natural hydrocarbon seeps ("chapopoteras") area and offshore rivers, but there is no accumulation of oil related trace elements in these areas. However, the comparison with international sediment quality benchmarks indicates that Cd, Cr and Ni concentrations are above the threshold effect level, and also As, Ba and Cu are above the probable effect level benchmarks, which indicate that these element concentrations might be of potential ecological concern. Comprehensive studies involving different proxies, and assessing pre-industrial conditions, must be undertaken before assessing environmental health of marine benthic ecosystems.

Spatial and temporal distribution of heavy metal concentrations and enrichment in the southern Gulf of Mexico.

Trace element (As, Co, Cr, Cu, Ni, Pb, V and Zn) enrichment trends during the past century, were assessed in thirteen 210Pb-dated sediment cores from the southern Gulf of Mexico, with the purpose to evaluate the impact on the environment, and potentially on public health, of the offshore oil industry and of oil spills such as that of the Ixtoc1 well blowout in 1979. The trace element composition was quite homogeneous among cores; and the pre-industrial concentrations of Ba, Cr, Cu and Ni are naturally high in the region, as to reach levels of potential ecological concern. The influence of multiple and simultaneous processes (e.g. industrial activities, natural seeps, fluvial discharges) on the trace element concentrations is difficult to disentangle. Some cores suggested long-term preservation of putative oil spill traces, although it was not possible to attribute their origin. The Al-normalized redox element ratios, and the crude oil contamination ratio, suggested that these events occurred along almost four decades, and that the traces attributed to the Ixtoc1 spill were comparable to background conditions, most likely owing to active natural oil seeps in the area. In most cases there was a trend towards a lowering in the supply of trace elements; this might be associated with environmental controls in the region since the 1980s. This study highlights the relevance of using dated environmental archives to reconstruct the historical trends of trace metal contamination in areas where long-term environmental studies are scarce.

Facilitators and barriers to modifying dietary and hygiene behaviours as adjuvant treatment in patients with depression in primary care: a qualitative study.

BACKGROUND: Major depression is a highly prevalent condition. Its pathogenesis is related to a wide variety of biological and psychosocial factors and among these is factors related to lifestyle. Lifestyle-based interventions seem to be appropriate strategies as coadjutant treatment. The objective of this study is to explore and identify expectations and experiences of both patients and healthcare professionals that can point to the main barriers and facilitators with regard to the promotion of healthy dietary and hygiene behaviours in patients suffering from major depression. METHODS: A qualitative design was used to collect information from a wide range of purposefully and theoretically guided samples of depressed patients and health professionals from Primary Care (PC). Both in-depth interviews and discussion groups were used. A standardized protocol was designed to guide the interviews and groups, including the preparation of a topic list to be addressed, with previously tested, open suggestions that could be of interest. A thematic analysis was performed from grounded theory in order to explore, develop and define until saturation the emergent categories of analysis derived from the individual interview and group data. RESULTS: Both patients as well as PC professionals noted a series of central aspects with respect to the implementation of a programme for the acquisition of healthy dietary and hygiene habits for depressive patients, which may be organized around 'personal', 'programmatic', and 'transversal' aspects. As for the personal aspects, categories regarding 'patient history', and 'disposition' were found; the programmatic aspects included categories such as 'presentation and monitoring', and modification of 'cognitive' and 'behavioural' habits; whereas the transversal aspects comprised the possibilities of 'social support' and defining categories of 'objectives'. CONCLUSION: The implementation of intervention programmes that combine dietary and hygiene-related factors in patients with depression is complex, given the nature of the disorder itself, and its symptoms such as apathy and feelings of guilt or incompetence. Key issues exist for the success of the intervention, such as the simplicity of guidelines, tailoring through motivational interviewing, prolonged and intense monitoring throughout the different stages of the disorder, and the provision of adequate feedback and social support. PC could be an appropriate level in which to implement these interventions.

Intervención enfermera para controlar la transmisibilidad cruzada de microorganismos multirresistentes en un servicio de hospitalización urológica / No disponible

Según el "Estudio de prevalencias de infecciones nosocomiales en España" de 2015, las localizaciones urológicas son la cuarta causa de infección hospitalaria, con una prevalencia del 19,72%. Con el fin de disminuir la incidencia de transmisiones cruzadas, derivadas del contacto con profesionales sanitarios y no sanitarios, pacientes, familiares y acompañantes, se propone una intervención enfermera basada en un programa de educación para la salud y dos seminarios de formación continuada. Se han elaborado seis herramientas, dirigidas a erradicar malas prácticas y actuaciones incorrectas, evaluadas a través de indicadores de proceso y de resultados. Tanto el programa educativo como la formación continuada se pueden implantar en otros servicios de hospitalización, con el correspondiente estudio de prevalencia de microorganimos multirresistentes, abriendo nuevas líneas de investigación

According to the "Study of Prevalence of Nosocomial Infections in Spain" 2015, urologic locations are the fourth leading cause of hospital infections, with a prevalence of 19.72%. In order to decrease the incidence of transmissions crusades, arising from the contact with health care and non-health care professionals, patients, family members and their companions, proposes a nurse intervention based on a program of education for health and two seminars of continuous training. Six tools have been developed, aimed at eradicating bad practices and improper practices, evaluated through indicators of process and results. Both the educational program such as continuous training, can be deployed to other hospitalization services with the corresponding study of prevalence of multiresistant microorganimos, opening new lines of research

Asociación del síndrome de hipogonadismo tardío y síndrome metabólico con el cáncer de próstata y su agresividad / Association between late-onset hypogonadism syndrome plus metabolic syndrome and prostate cancer and its aggressiveness

Objetivo: Evaluar la relación entre el cáncer de próstata (CaP) y la presencia de síndrome metabólico (SM) y síndrome de hipogonadismo tardío (SHT). Material y método: Estudio retrospectivo de 686 pacientes sometidos a biopsia prostática. Analizamos: variables demográficas, datos clínicos y resultados de la biopsia. Para diagnosticar el SM se utilizaron los criterios de la American Heart Association. Para el diagnóstico de SHT se utilizó el cuestionario ADAM y los niveles de testosterona (TT). Evaluamos la relación de la testosterona libre (TL) y testosterona biodisponible (TB) con el CaP y su agresividad y la utilidad de la ratio TT/PSA en el diagnóstico de CaP. Resultados: Mediana de edad 65 años. El SM no se asoció al CaP (39,4% vs 35% p = 0,1) pero sí a un CaP Gleason > 7 (50,4% vs 29,44% p = 0,002). El SHT, TL baja y TB baja se asociaron a una mayor presencia de CaP (51% vs 35% p = 0,02; 44,86% vs 33,33%, p = 0,03; 46,46% vs 33,08%, p = 0,01 respectivamente) y a mayor probabilidad de CaP Gleason >7 (61,54% vs 37,5% p = 0,02; 54,17% vs 34,12%, p = 0,02; 54,35% vs 34,48% p = 0,02 respectivamente). Además, la mediana de la ratio de TT/PSA fue significativamente menor en los pacientes con BxP positiva (p = 0.022). Conclusiones: el SM no se asoció con la probabilidad de tener CaP, pero sí con el CaP Gleason > 7. Por otro lado, el SHT presentó un mayor porcentaje de CaP y una mayor presencia de CaP Gleason > 7, al igual que los niveles bajos de TL y los niveles bajos de TB

Objective: To assess the relationship between prostate cancer (PC) and the presence of metabolic syndrome and late-onset hypogonadism (LOH) syndrome. Material and method: A retrospective study was conducted on 686 patients who underwent prostate biopsy. We analysed the demographic variables, clinical data and biopsy results. To diagnose metabolic syndrome, we employed the criteria of the American Heart Association. For the diagnosis of LOH syndrome, we employed the Androgen Deficiency in the Aging Male questionnaire and testosterone levels (TT). We evaluated the relationship between free testosterone (FT) and bioavailable testosterone (BT) on one hand and PC and its aggressiveness on the other, as well as the usefulness of the TT to prostate specific antigen (TT/PSA) ratio in the PC diagnosis. :Results The patient's median age was 65 years. Metabolic syndrome is not associated with PC (39.4% vs. 35%; P = .1) but is associated with a PC Gleason score > 7 (50.4% vs. 29.44%; P = .002). LOH, low FT and low BT are associated with an increased presence of PC (51% vs. 35%, P = .02; 44.86% vs. 33.33%, P = .03; and 46.46% vs. 33.08%, P = .01, respectively) and with an increased probability of a PC Gleason score > 7 (61.54% vs. 37.5%, P = .02; 54.17% vs. 34.12%, P = .02; 54.35% vs. 34.48%, P = .02, respectively). Additionally, the median TT/PSA ratio was significantly lower in patients with positive biopsies (P = .022). Conclusions: Metabolic syndrome was not associated with the probability of having PC but was associated with a PC Gleason score > 7. Moreover, LOH syndrome had a higher percentage of PC and a greater presence of PC Gleason scores > 7, as did low levels of FT and low levels of BT

Opsin evolution in the Ambulacraria.

Opsins--G-protein coupled receptors involved in photoreception--have been extensively studied in the animal kingdom. The present work provides new insights into opsin-based photoreception and photoreceptor cell evolution with a first analysis of opsin sequence data for a major deuterostome clade, the Ambulacraria. Systematic data analysis, including for the first time hemichordate opsin sequences and an expanded echinoderm dataset, led to a robust opsin phylogeny for this cornerstone superphylum. Multiple genomic and transcriptomic resources were surveyed to cover each class of Hemichordata and Echinodermata. In total, 119 ambulacrarian opsin sequences were found, 22 new sequences in hemichordates and 97 in echinoderms (including 67 new sequences). We framed the ambulacrarian opsin repertoire within eumetazoan diversity by including selected reference opsins from non-ambulacrarians. Our findings corroborate the presence of all major ancestral bilaterian opsin groups in Ambulacraria. Furthermore, we identified two opsin groups specific to echinoderms. In conclusion, a molecular phylogenetic framework for investigating light-perception and photobiological behaviors in marine deuterostomes has been obtained.

Economic analysis of thrombo inCode, a clinical-genetic function for assessing the risk of venous thromboembolism.

BACKGROUND: Patients with venous thromboembolism (VTE) commonly have an underlying genetic predisposition. However, genetic tests nowadays in use have very low sensitivity for identifying subjects at risk of VTE. Thrombo inCode(®) is a new genetic tool that has demonstrated very good sensitivity, thanks to very good coverage of the genetic variants that modify the function of the coagulation pathway. OBJECTIVE: To conduct an economic analysis of risk assessment of VTE from the perspective of the Spanish National Health System with Thrombo inCode(®) (a clinical-genetic function for assessing the risk of VTE) versus the conventional/standard method used to date (factor V Leiden and prothrombin G20210A). METHODS: An economic model was created from the National Health System perspective, using a decision tree in patients aged 45 years with a life expectancy of 81 years. The predictive capacity of VTE, based on identification of thrombophilia using Thrombo inCode(®) and using the standard method, was obtained from two case-control studies conducted in two different populations (S. PAU and MARTHA; 1,451 patients in all). Although this is not always the case, patients who were identified as suffering from thrombophilia were subject to preventive treatment of VTE with warfarin, leading to a reduction in the number of VTE events and an increased risk of severe bleeding. The health state utilities (quality-adjusted life-years [QALYs]) and costs (in 2013 EUR values) were obtained from the literature and Spanish sources. RESULTS: On the basis of a price of EUR 180 for Thrombo inCode(®), this would be the dominant option (more effective and with lower costs than the standard method) in both populations. The Monte Carlo probabilistic analyses indicate that the dominance would occur in 100 % of the simulations in both populations. The threshold price of Thrombo inCode(®) needed to reach the incremental cost-effectiveness ratio (ICER) generally accepted in Spain (EUR 30,000 per QALY gained) would be between EUR 3,950 (in the MARTHA population) and EUR 11,993 (in the S. PAU population). CONCLUSION: According to the economic model, Thrombo inCode(®) is the dominant option in assessing the risk of VTE, compared with the standard method currently used.
