Thuidium abietinum (Hedw.) B., S, & G. s.l. : morfologia i distribució a la Península Ibèrica

S'ha realitzat l'estudi morfolbgic dels taxons que comprèn Thuidium abietinum s.1. S'observen, en moltes mostres, diferències pel que fa a les dues varietats: var. abietinum i var. hystricosum, perd alguns exemplars presenten uns caràcters particulars que no coincideixen totalment amb els de les dues varietats citades; corresponen a la fo. intermedium de la var. abietinum. Es destaquen les diferències més importants, com la disposició, forma i mida dels fillidis i la morfologia de la trama cel·lular. Tots els exemplars estudiats són estèrils. Es presenten també dibuixos originals, l'ecologia i la distribució dels tres tàxons en la geografia ibèrica.A comparative morphological study based on the garnetophitic characters of the T. abietinum s.1. taxa has been made. Most samples shows the characteristics of the two varieties: var. abietinum and var. hystricosum but, some species does not conform them. I have recognized the fo. intermedium of var. abietinum in these samples. Here, I show the most importants features about the disposition, shape and size of the leaves and the morphological celular characters. All the specimens are steriles. For each of the taxa, original iconography, the ecology and the current geographical distribution in the Iberian Peninsula are also showed

Contribució a la brioflora de les serres del Montsant i de la Llena

S'ha elaborat un catàleg de briòfits de les Serres del Montsant i de la Llena (Serralada Pre-litoral Catalana), amb un total de 128 tàxons (21 hepàtiques i 107 molses), seguit també d'una breu descripció de la vegetació briofítica de la zona.A catalogue of 128 bryophytic taxa (21 hepatics and 107 mosses) from de mountains of Montsant and Llena has been prepared, followed by a short description of the bryological vegetation

La brioflora de la Sierra de Gata

A catalog of 202 bryophytic taxa from Sierra de Gata is presented, with some comments on interesting species such as Mielichhoferia pontevedrensis, Andreaea crassinervia, Rhynchostegium alopecuroides, etc. Oceanic, suboceanic and temperate corological elements are the most important while the mediterranean and submediterranean ones are less represented.Catálogo de 202 táxones de briófitos conocidos de la Sierra de Gata y comentarios sobre algunas especies interesantes como Mielichhoferia pontevedrensis, Andreaea crassinervia, Rhynchostegium alopecuroides, etc. Se observa una dominancia de 10s elementos corológicos oceánico, suboceánico y templado y una pobreza de los elementos mediterráneo y submediterráneo

Els Briòfits de la Réserve Naturelle de la Forêt de la Massane (SE de França)

Hem identificat 153 tàxons dels quals 121 són molses i 32, hepàtiques. Mnium hornum entapissa una bona part del sòl de la fageda. Jungermannia subulata és abundant a les parts humides a les vores dels rierols. Els nombrosos epífits sobre faigs o roures formen una bona cobertura i tenen una excel·lent vitalitat. Predominen les espècies de distribució temperada, mentre que les boreals, suboceàniques i oceanicomediterrànies són menys abundants. D'una altra banda, malgrat la proximitat al mar de la zona de la Reserva, les de distribució mediterrània i submediterrània són escasses.153 species were identified; 121 mosses and 32 hepaticae. Mnium hornum covers the larger part of the beechwood soil. Jungermannia subulata is abundant on the wet stream margins. Epiphytic species grow copiously on beech and oak trees. The temperate species are the best represented and boreal, suboceanic, and oceanic-mediterranean species are also abundant. In spite of the nearness of the sea, mediterranean and submediterranean species are rare

Estudi de la brioflora dels Ports de Beseit

A catalog of the 186 bryophytic taxa found in the calcareous mountain area of the Ports de Beseit is given, together with a short description of the bryological vegetation, and comments on interesting species such as Acaulon dertosense, Frullania muscicolu, Brachythecium olympicum, Rhynchostegiella compacta, Tortula solmsii, etc. Chorological and ecological spectra are also given.Presentem el catàleg dels 186 taxons briofítics trobats als Ports de Beseit, junt amb una succinta descripció de la vegetació briofítica i comentaris sobre certes especies interessants, com ara Acaulon dertosense, Frullania muscicola, Brachythecium olympicum, Rhynchostegiella compacta, Tortula solmsii, etc. Donem també els espectres corologies i de diversos factors ecologies

Elective Cancer Surgery in COVID-19-Free Surgical Pathways During the SARS-CoV-2 Pandemic: An International, Multicenter, Comparative Cohort Study.

PURPOSE: As cancer surgery restarts after the first COVID-19 wave, health care providers urgently require data to determine where elective surgery is best performed. This study aimed to determine whether COVID-19-free surgical pathways were associated with lower postoperative pulmonary complication rates compared with hospitals with no defined pathway. PATIENTS AND METHODS: This international, multicenter cohort study included patients who underwent elective surgery for 10 solid cancer types without preoperative suspicion of SARS-CoV-2. Participating hospitals included patients from local emergence of SARS-CoV-2 until April 19, 2020. At the time of surgery, hospitals were defined as having a COVID-19-free surgical pathway (complete segregation of the operating theater, critical care, and inpatient ward areas) or no defined pathway (incomplete or no segregation, areas shared with patients with COVID-19). The primary outcome was 30-day postoperative pulmonary complications (pneumonia, acute respiratory distress syndrome, unexpected ventilation). RESULTS: Of 9,171 patients from 447 hospitals in 55 countries, 2,481 were operated on in COVID-19-free surgical pathways. Patients who underwent surgery within COVID-19-free surgical pathways were younger with fewer comorbidities than those in hospitals with no defined pathway but with similar proportions of major surgery. After adjustment, pulmonary complication rates were lower with COVID-19-free surgical pathways (2.2% v 4.9%; adjusted odds ratio [aOR], 0.62; 95% CI, 0.44 to 0.86). This was consistent in sensitivity analyses for low-risk patients (American Society of Anesthesiologists grade 1/2), propensity score-matched models, and patients with negative SARS-CoV-2 preoperative tests. The postoperative SARS-CoV-2 infection rate was also lower in COVID-19-free surgical pathways (2.1% v 3.6%; aOR, 0.53; 95% CI, 0.36 to 0.76). CONCLUSION: Within available resources, dedicated COVID-19-free surgical pathways should be established to provide safe elective cancer surgery during current and before future SARS-CoV-2 outbreaks
