Three species of the genus Lichenochora (Phyllachorales, not lichenized lichenicolous ascomycetes) are decribed as new to science: L. aipoliae Etayo, Nav.-Ros. et Coppins sp. nov., that grows on Physcia aipolia, L. coppinsii Etayo et Nav.-Ros. sp. nov., on Protopannaria pezizoides, and L. paucispora Etayo et Nav.-Ros. sp. nov., on Bilimbia sabuletorum. A new combination to the genus is proposed: L. lepidiotae (Anzi) Etayo et Nav.-Ros. comb. nov., on Fuscopannaria praetermissa. The description of the anamorph of Lichenochora epidesertorum is included. Raports of known range extensions for different species of the genus: L. constrictella is mentioned by first time for continental America (USA) and L. aprica for Spain. An identification key to the species of Lichenochora are included.Una combinación y tres especies nuevas de Lichenochora (Phyllachorales, ascomicetes liqueníc olas), y notas adicionales para el género. Descripción de tres especies nuevas del género Lichenochora (Phyllachorales, ascomicetes liquenícolas no liquenizados): L. aipoliae Etayo, Nav.-Ros. et Coppins sp. nov., que crece sobre Physcia aipolia, L. coppinsii Etayo et Nav.-Ros. sp. nov., sobre Protopannaria pezizoides, y L. paucispora Etayo et Nav.-Ros. sp. nov., sobre Bilimbia sabuletorum; y propuesta de una nueva combinación para el género: L. lepidiotae (Anzi) Etayo et Nav.-Ros. comb. nov., un hongo propio de Fuscopannaria praetermissa. Se incluye la descripción del anamorfo de Lichenochora epidesertorum; se aportan nuevas citas territoriales para diferentes especies del género: L. constrictella constituye la primera cita para America continental y L. aprica primera cita para España; y se incluyen unas claves de identificación para las especies conocidas del género

Sobre la presencia de pseudopyrenidium tartaricola (eurotiomycetes, hongos liquenícolas) en los Pirineos

Se menciona la presencia de Pseudopyrenidium tartaricola en los Pirineos, en la provincia de Huesca (España). P. tartaricola es un hongo liquenícola de distribución predominantemente ártico-boreal que crece sobre diferentes especies terrícolas y muscícolas de Ochrolechia. La cita aportada constituye la primera mención para la micoflora española, y representa la localidad europea más meridional conocida para este hongo. Esta nota florística se complementa con iconografía original del hábito y de las ascósporas de la especie.The presence of Pseudopyrenidium tartaricola is mentioned in the Pyrenees, specifically in the province of Huesca (Spain). Ps. tartaricola is a lichenicolous fungus with predominantly arctic-boreal distribution, which grows on different terricolous or muscicolous species of Ochrolechia. The provided record is the first mention for Spanish mycoflora, and corresponds to the southernmost European locality known for this fungus. This floristic note is complemented with original iconography of the habit and ascòspores

Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study

Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat
