Endless forms most frustrating: disentangling species boundaries in the group (), 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.

Lack of awareness of systemic lupus erythematosus and its consequences in a cohort of moderate and severe patients in Spain: The LupusVoice study.

Background And Objectives: Systemic lupus erythematosus (SLE) is an autoimmune condition that can highly impact patients' quality of life (QoL). However, there is a lack of knowledge about SLE, affecting the general population and health care professionals (HCPs) alike. This lack of knowledge has negative implications for patients and the healthcare system, worsening prognosis, negatively impacting QoL, and increasing healthcare utilization.

Bacterial communities associated with an island radiation of lichen-forming fungi.

Evolutionary radiations are one of the most striking processes biologists have studied in islands. A radiation is often sparked by the appearance of ecological opportunity, which can originate in processes like trophic niche segregation or the evolution of key innovations. Another recently proposed mechanism is facilitation mediated by the bacterial communities associated with the radiating species.

Gender perspective in the implementation of hygiene in cardiology intensive care.

Introduction: Hygiene in critical patients is an essential daily care, provided under safe conditions, to promote comfort and maintain the integrity of skin and mucous membranes, however, it can generate feelings of dependence and vulnerability in patients. The aim of this post hoc study is to know the differences in satisfaction and lived experience regarding bed hygiene in an intensive care unit according to biological sex and gender perspective.

Methods: Observational, descriptive and prospective study in which an ad hoc questionnaire was administered to 148 conscious and oriented patients of legal age.

, Not , Is the Main Photobiont of (, ).

This study explores the diversity of photobionts associated with the Mediterranean lichen-forming fungus . For this purpose, we sequenced the whole ITS rDNA region by Sanger using a metabarcoding method for ITS2. A total of 41 specimens from Greece, Italy, France, Portugal, and Spain were studied.

Emotional response of critically-ill cardiac patients during hygiene procedures in intensive care: a prospective and descriptive study.

Objective: to analyze the emotional response of critically-ill conscious patients during daily hygiene procedures in a Cardiology Intensive Care Unit and to compare it based on the existence of previous experiences or not.

Method: a prospective and descriptive study. A 30-item ad hoc survey based on the first-day hygiene procedures was applied to 148 patients.

Innovative approaches to accurately assess the effectiveness of biocide-based treatments to fight biodeterioration of Cultural Heritage monuments.

The development of diagnostic methods to accurately assess the effects of treatments on lithobiont colonization remains a challenge for the conservation of Cultural Heritage monuments. In this study, we tested the efficacy of biocide-based treatments on microbial colonization of a dolostone quarry, in the short and long-term, using a dual analytical strategy. We applied a metabarcoding approach to characterize fungal and bacterial communities over time, integrated with microscopy techniques to analyze the interactions of microorganisms with the substrate and evaluate the effectiveness.

Ocean crossers: A tale of disjunctions and speciation in the dwarf-fruticose Lichina (lichenized Ascomycota).

Lichens thrive in rocky coastal areas in temperate and cold regions of both hemispheres. Species of the genus Lichina, which form characteristic black fruiting thalli associated with cyanobacteria, often create distinguishable bands in the intertidal and supralittoral zones. The present study uses a comprehensive specimen dataset and four gene loci to (1) delineate and discuss species boundaries in this genus, (2) assess evolutionary relationships among species, and (3) infer the most likely causes of their current geographic distribution in the Northern and Southern hemispheres.

Mitral valve-in-valve implantation: A case report.

Introduction: Mitral valve-in-valve implantation is a new therapeutic tool in the field of structural interventional cardiology for patients with bioprosthetic dysfunction due to severe mitral valve regurgitation and high surgical risk. The objective was to develop an individualised nursing care plan for a patient undergoing this procedure; the first case in our centre.

Case Description: A 75-year-old woman, independent for activities of daily living, with a history of chronic renal failure and biological mitral valve replacement due to rheumatic valve disease.

Clinical Debriefing in Cardiology Teams: A National Survey in Spain.

Background: Clinical debriefing (CD) improves patient safety and builds team resilience.

Purpose: We describe the current use of CD by multiprofessional Spanish cardiology team members.

Methods: A self-administered survey exploring 31 items was disseminated online in October 2020.

The Role of Photobionts as Drivers of Diversification in an Island Radiation of Lichen-Forming Fungi.

Speciation in oceanic islands has attracted the interest of scientists since the 19th century. One of the most striking evolutionary phenomena that can be studied in islands is adaptive radiation, that is, when a lineage gives rise to different species by means of ecological speciation. Some of the best-known examples of adaptive radiation are charismatic organisms like the Darwin finches of the Galapagos and the cichlid fishes of the great African lakes.

Lived Experiences of Hospitalized COVID-19 Patients: A Qualitative Study.

The COVID-19 pandemic has resulted in many hospitalized patients and deaths worldwide. Coronavirus patients were isolated from their relatives and visits were banned to prevent contagion. This has brought about a significant change in deeply rooted care habits in Mediterranean and Latin American countries where the family normally accompanies vulnerable hospitalized patients.

(Dothideomycetes, Dictyosporiaceae), a new genus of lichenicolous fungi on s. lat. for the species complex.

Two lichenicolous fungi, one growing on the thallus of in the United Kingdom (Scotland) and the other in apothecia of and in northwestern North America (Alaska and British Columbia) and northeast Asia (Russian Far East, Khabarovsk Krai), show similarities to the species originally described as (later transferred to s. lat and ) from a s. lat.

Experiences of nursing students as healthcare aid during the COVID-19 pandemic in Spain: A phemonenological research study.

Background: The coronavirus disease (COVID-19) pandemic has caused a worldwide health and social crisis directly impacting the healthcare system. Hospitals had to rearrange its structure to meet clinical needs. Spain has been experiencing a shortage of working nurses.

Lichens and associated fungi from Glacier Bay National Park, Alaska.

Lichens are widely acknowledged to be a key component of high latitude ecosystems. However, the time investment needed for full inventories and the lack of taxonomic identification resources for crustose lichen and lichenicolous fungal diversity have hampered efforts to fully gauge the depth of species richness in these ecosystems. Using a combination of classical field inventory and extensive deployment of chemical and molecular analysis, we assessed the diversity of lichens and associated fungi in Glacier Bay National Park, Alaska (USA), a mixed landscape of coastal boreal rainforest and early successional low elevation habitats deglaciated after the Little Ice Age.

A new genus, , and a novel nutritional mode revealed in the family Malmideaceae (Lecanoromycetes, Ascomycota).

Lichen-inhabiting fungi are highly specialized mycoparasites, commensals or rarely saprotrophs, that are common components of almost every ecosystem, where they develop obligate associations with lichens. Their relevance, however, contrasts with the relatively small number of these fungi described so far. Recent estimates and ongoing studies indicate that a significant fraction of their diversity remains undiscovered and may be expected in tropical regions, in particular in hyperdiverse fog-exposed montane forests.

Functional ecology of soil microbial communities along a glacier forefield in Tierra del Fuego (Chile).

A previously established chronosequence from Pia Glacier forefield in Tierra del Fuego (Chile) containing soils of different ages (from bare soils to forest ones) is analyzed. We used this chronosequence as framework to postulate that microbial successional development would be accompanied by changes in functionality. To test this, the GeoChip functional microarray was used to identify diversity of genes involved in microbial carbon and nitrogen metabolism, as well as other genes related to microbial stress response and biotic interactions.

From Alaska to Antarctica: Species boundaries and genetic diversity of Prasiola (Trebouxiophyceae), a foliose chlorophyte associated with the bipolar lichen-forming fungus Mastodia tessellata.

Symbiotic associations between green algae (Chlorophyta) and fungi give rise to morphologically and eco-physiologically distinct entities, or so-called, lichens. In one of the most peculiar of these associations, the partners are species of the macroscopic genus Prasiola (Trebouxiophyceae) and the ascomycete Mastodia tessellata (Verrucariaceae). This is the only known case of a lichen symbiosis involving a foliose green alga.

Heveochlorella (Trebouxiophyceae): a little-known genus of unicellular green algae outside the Trebouxiales emerges unexpectedly as a major clade of lichen photobionts in foliicolous communities.

Foliicolous lichens are formed by diverse, highly specialized fungi that establish themselves and complete their life cycle within the brief duration of their leaf substratum. Over half of these lichen-forming fungi are members of either the Gomphillaceae or Pilocarpaceae, and associate with Trebouxia-like green algae whose identities have never been positively determined. We investigated the phylogenetic affinities of these photobionts to better understand their role in lichen establishment on an ephemeral surface.
