Briòfits de l'Alt Empordà

En aquest treball presentem el catàleg dels Briòfits coneguts fins ara a l'Alt Empordà. Citem 181 espècies de molses i 59 d'hepàtiques. La major part de les dades es deuen a la Dra. Creu Casas que va estudiar molt intensament é1 Cap de Creus fent troballes molt notables: Entosthodon durieui var. mustaphae, molsa nordafricana desconeguda a Europa, Exormotheca pustulosa, hepàtica citada a Monchique (Portugal), i la varietat nova de l'espècie sudafricana Oedipodiella australis var. catalaunica. Més tard, va recol·lectar Leucobryum juniperoideum a Sant Llorenç de la Muga, espècie considerada oceànica. Es troba amb altres espécies de tendència atlàntica com Harpalejeunea ovata, Hedwigia integrifolia i Campylopus flexuosus. Cal destacar també la darrera recol·lecció al Cap Norfeu de Bryum gemmiluscens, primera cita a la Península

Els Briòfits de les basses de l?Albera, Alt Empordà

Hem estudiat unes basses i unes depressions temporalment inundades en les quals, en evaporar- se l'aigua, sobre el sòl emergit, s'hi observa una elevada diversitat i abundància de briòfits. Per a la distribució dels briòfits hem establert tres zones concèntriques en relació amb el grau d'humitat. En la més externa i excepcionalment inundada, hi destaquen les hepàtiques Riccia gougetiana i Fossombronia maritima i diverses antocerotes; en la zona emergida, Pseudephemerum nitidum, Archidium alternifolium i un nombre elevat d'espècies del gènere Riccia, com R. macro-carpa i R. warnstorfii. En algunes basses on el període d'inundació és llarg, hi hem observat molses pleurocàrpiques, com Amblystegium riparium i Drepanocladus aduncus.Hemos estudiado diversas charcas y depresiones inundadas temporalmente en las que al evaporarse el agua, y sobre el suelo emergente, se observa una elevada diversidad y abundancia de briófitos. Para la distribución de los briófitos hemos establecido tres zonas concéntricas en relación con el grado de humedad. En la más externa y excepcionalmente inundada destacamos las hepáticas Riccia gougetiana y Fossombronia maritima y diversas antocerotas; en la zona emergida Pseudephemerum nitidum, Archidium alternifolium y un elevado numero de especies del género Riccia como R. macrocarpa y R. warnstorfii. En algunas charcas donde el periodo de inundación es prolongado hemos observado musgos pleurocárpicos como Amblystegium riparium y Drepanocladus aduncus.We have studied some depressions and areas temporarily flooded where after the water evaporates, a high diversity and abundance of bryophyta can be observed on the emerged soil. For the distribution of these bryophytes we have established three concentric zones according to their humidity level. At the most external one, which is seldom flooded, the hepatics Riccia gougetiana and Fossombronia maritima were found, as well as various Anthocerotae. At the emerged zone Pseudephemerum nitidum, Archidium alternifolium and a high number of Riccia species, such as R. macrocarpa and R. warnstorfii could be found. In some depressions with a long flooding period, we observed pleurocarpous mosses such as Amblystegium riparium and Drepanocladus aduncus

Knowledge, attitudes, and training in tobacco dependence and cessation treatment among nursing strudents in Catalonia (ECTEC study): cross-sectional study

Nursing students are part of the future health labor force; thus, knowing their knowledge and participation in tobacco control is of importance. Multicenter cross-sectional study conducted to assess nursing students' knowledge, attitudes, and training in tobacco dependence and treatment at 15 nursing schools in Catalonia. We employed a self-administered questionnaire. A total of 4,381 students participated. Few respondents (21.1%) knew how to assess smokers' nicotine dependence, and less than half (41.4%) knew about the smoking cessation therapies. Most (80%) had been educated on the health risks of smoking, 50% about the reasons why people smoke and one-third on how to provide cessation aid. Students in the last years of training were more likely to have received these two contents. Nursing students lack sufficient knowledge to assess and treat tobacco dependence and are rarely trained in such subjects. Nursing curricula in tobacco dependence and treatment should be strengthened to tackle the first preventable cause of disease worldwide

Association of APOA5 and APOC3 genetic polymorphisms with severity of hypertriglyceridemia in patients with cutaneous T-Cell lymphoma treated with bexarotene

Importance: hypertriglyceridemia is the most frequent and limiting adverse effect of bexarotene therapy in cutaneous T-cell lymphoma (CTCL). Despite standard prophylactic measures, there is a wide variability in the severity of this complication, which could be associated with both genetic and environmental factors. Objectives: to analyze the association between genetic polymorphisms of apolipoprotein genes APOA5, APOC3, and APOE and the severity of hypertriglyceridemia during bexarotene therapy and to optimize patient selection for bexarotene therapy based on adverse effect profile. Design, Setting, and Participants: this case series study was conducted in 12 university referral hospitals in Spain from September 17, 2014, to February 6, 2015. One hundred twenty-five patients with a confirmed diagnosis of CTCL who had received bexarotene therapy for at least 3 months were enrolled. Nine patients were excluded owing to missing analytic triglyceride level data, leaving a study group of 116 patients. Data on demographic and cardiovascular risk factor were collected, and a complete blood analysis, including lipid profile and genetic analysis from a saliva sample, was performed. Main Outcomes and Measures: primary outcomes were the maximal triglyceride levels reported in association with the minor alleles of the polymorphisms studied. Results: among 116 patients, the mean (SD) age was 61.2 (14.7) years, 69 (59.5%) were men, and 85 (73.2%) had mycosis fungoides, the most prevalent form of CTCL. During bexarotene therapy, 96 patients (82.7%) experienced hypertriglyceridemia, which was severe or extreme in 8 of these patients (8.3%). Patients who carried minor alleles of the polymorphisms did not show significant differences in baseline triglyceride concentrations. After bexarotene treatment, carriers of at least 1 of the 2 minor alleles of APOA5 c.-1131T>C and APOC3 c.*40C>G showed lower levels of triglycerides than noncarriers (mean [SD], 241.59 [169.91] vs 330.97 [169.03] mg/dL, respectively; P = .02). Conclusions and Relevance: these results indicate that the screening of APOA5 and APOC3 genotypes may be useful to estimate changes in triglyceride concentrations during bexarotene treatment in patients with CTCL and also to identify the best candidates for bexarotene therapy based on the expected adverse effect profile

Preoperative oral antibiotic prophylaxis reduces Pseudomonas aeruginosa surgical site infections after elective colorectal surgery: a multicenter prospective cohort study

BACKGROUND: Healthcare-associated infections caused by Pseudomonas aeruginosa are associated with poor outcomes. However, the role of P. aeruginosa in surgical site infections after colorectal surgery has not been evaluated. The aim of this study was to determine the predictive factors and outcomes of surgical site infections caused by P. aeruginosa after colorectal surgery, with special emphasis on the role of preoperative oral antibiotic prophylaxis. METHODS: We conducted an observational, multicenter, prospective cohort study of all patients undergoing elective colorectal surgery at 10 Spanish hospitals (2011-2014). A logistic regression model was used to identify predictive factors for P. aeruginosa surgical site infections. RESULTS: Out of 3701 patients, 669 (18.1%) developed surgical site infections, and 62 (9.3%) of these were due to P. aeruginosa. The following factors were found to differentiate between P. aeruginosa surgical site infections and those caused by other microorganisms: American Society of Anesthesiologists' score III-IV (67.7% vs 45.5%, p = 0.001, odds ratio (OR) 2.5, 95% confidence interval (95% CI) 1.44-4.39), National Nosocomial Infections Surveillance risk index 1-2 (74.2% vs 44.2%, p < 0.001, OR 3.6, 95% CI 2.01-6.56), duration of surgery ≥75thpercentile (61.3% vs 41.4%, p = 0.003, OR 2.2, 95% CI 1.31-3.83) and oral antibiotic prophylaxis (17.7% vs 33.6%, p = 0.01, OR 0.4, 95% CI 0.21-0.83). Patients with P. aeruginosa surgical site infections were administered antibiotic treatment for a longer duration (median 17 days [interquartile range (IQR) 10-24] vs 13d [IQR 8-20], p = 0.015, OR 1.1, 95% CI 1.00-1.12), had a higher treatment failure rate (30.6% vs 20.8%, p = 0.07, OR 1.7, 95% CI 0.96-2.99), and longer hospitalization (median 22 days [IQR 15-42] vs 19d [IQR 12-28], p = 0.02, OR 1.1, 95% CI 1.00-1.17) than those with surgical site infections due to other microorganisms. Independent predictive factors associated with P. aeruginosa surgical site infections were the National Nosocomial Infections Surveillance risk index 1-2 (OR 2.3, 95% CI 1.03-5.40) and the use of oral antibiotic prophylaxis (OR 0.4, 95% CI 0.23-0.90). CONCLUSIONS: We observed that surgical site infections due to P. aeruginosa are associated with a higher National Nosocomial Infections Surveillance risk index, poor outcomes, and lack of preoperative oral antibiotic prophylaxis. These findings can aid in establishing specific preventive measures and appropriate empirical antibiotic treatment
