Sobre la posición sistemática de Choreonema Schmitz (Corallinaceae, Rhodophyta)

Scanning electron microscopy of conceptacle of the parasite Choreonema thuretii (Bornet) Schmitz reveals the Jania-type surface, only found in members of tribe Janieae (GARBARY & JOHANSEN, 1982). The recognition of Choreonemeae Svedelius (1911) as a evolutively regressive tribe of subfamily Corallinoideae is proposed.La superficie de los conceptáculos de Choreonema thuretii (Bornet) Schmitz observados con el microscopio electrónico de barrido, muestran los caracteres de la superficie tipo-Jania, exclusivos de la tribu Janieae, descritos por GARBARY & JOHANSEN (1982). Se propone reutilizar la tribu Choreonemeae Svedelius (1911), únicamente para este parásito, e incluirla como una tribu evolutivamente regresiva de la subfamilia Corallinoideae

Application of 3D images for the interpretation of bryophytes in the teaching of Botany

Los dos «Proyectos de Innovación Educativa» concedidos, el primero por el Vicerrectorado de Calidad Institucional e Innovación Educativa de la Universidad de La Laguna (ULL) en la convocatoria 2014-2015 y el segundo por el actual Vicerrectorado de Docencia en la convocatoria 2015-2016, a tres profesoras del Área de Botánica, implicadas en la docencia de esta materia en 3 asignaturas («Botánica 1», «Botánica» y «Botánica y Fisiología Vegetal») de 3 titulaciones de la ULL (Grado en Biología, Grado en Ciencias Ambientales y Grado en Farmacia respectivamente), nos han permitido contratar los servicios de una diseñadora gráfica para la elaboración de las imágenes 3D de la parte del «Manual de prácticas de Botánica on-line» correspondiente a los «Briófitos». En el primer proyecto (octubre 2014-noviembre 2015) abordamos los «Briófitos foliosos» y en el segundo (octubre 2015-noviembre 2016) los «Briófitos talosos». Dado que el alumnado, en el entorno virtual, ya dispone de la primera parte del manual dedicada a los «Briófitos foliosos», en este trabajo además de dar a conocer este nuevo recurso didáctico, presentamos la valoración inicial de su uso y acogida por parte del alumnado en las prácticas de laboratorio de la asignatura «Botánica» del Grado de Ciencias Ambientales. Dicha evaluación se realizó mediante un cuestionario anónimo, usando sistemas de respuesta personal (clickers). Los resultados obtenidos nos permiten afirmar que las ilustraciones 3D para las cuales se pidió la financiación han despertado el interés del alumnado, les han servido para comprender mejor la terminología y conceptos del manual, y éste a su vez está estructurado de acuerdo con las prácticas y les ha sido útil en su proceso de aprendizajeThe two «Educational Innovation Projects» awarded by the Vicechancellor for Institutional Quality and Educational Innovation of the University of La Laguna (ULL) in the 2014-2015 call, and by the current Vice-chancellor for Teaching in the 2015-2016 call to three professors of the Botany area involved in the teaching of this discipline in 3 subjects («Botany 1», «Botany» and «Botany and Plant Physiology») of 3 ULL degrees (Degree in Biology, Environmental Sciences and Pharmacy, respectively), have allowed us to hire the services of a graphic designer for the elaboration of the 3D images of the part of the «Manual of practices of Botany on-line» corresponding to the «Bryophytes». In the first project (October 2014-November 2015) we addressed the «foliate bryophytes» while the «Thallose bryophytes» were addressed in the second (October 2015-November 2016). Since the students already had the first part of the manual dedicated to the «Foliose bryophytes» in their virtual classroom, in this work, apart from presenting this new didactic resource, we present the initial assessment of its use and acceptance by part of the students in the laboratory practices of the subject «Botany» of the Degree of Environmental Sciences. This evaluation was developed using an anonymous questionnaire carried out with personal response systems (clickers). The obtained results allow us to affirm that the 3D illustrations for which funding was requested, have aroused students’ interest, have helped them to better understand the terminology and concepts of the manual which is structured in accordance with the practices and has been useful to them in their learning process

Diagnostic yield of chest and thumb ECG after cryptogenic stroke, Transient ECG Assessment in Stroke Evaluation (TEASE): an observational trial

Objective In stroke survivors, atrial fibrillation (AF) is typically evaluated solely by short-term ECG monitoring in the stroke unit. Prolonged continuous ECG monitoring or insertable cardiac monitors require substantial resources. Chest and thumb ECG could provide an alternative means of AF detection, which in turn could allow prompt anticoagulation to prevent recurrent stroke. The objective of this study was to assess the yield of newly diagnosed AF during 28 days of chest and thumb ECG monitoring two times per day in cryptogenic stroke.Methods This study, Transient ECG Assessment in Stroke Evaluation, included patients who had a stroke from Region Gävleborg, Sweden, between 2017 and 2019. Patients with a recent ischaemic stroke without documented AF (or other reasons for anticoagulation) before or during ECG evaluation in the stroke unit were evaluated using the Coala Heart Monitor connected to a smartphone application for remote monitoring.Results The prespecified number of 100 patients (mean age 67.6±10.8 years; 60% men) was analysed. In nine patients (9%, number needed to screen 11) AF but no other significant atrial arrhythmias (>30 s) was diagnosed. The mean CHA2DS2-VASc score was similar among patients with AF and no AF (4.9±1.1 vs 4.3±1.3; p=0.224) and patients with AF were older (74.3±9.0 vs 66.9±10.8; p=0.049). Patients performed on average 90.1%±15.0% of scheduled transmissions.Conclusion In evaluation of cryptogenic stroke, 9% of patients had AF detected using chest and thumb ECG two times per day during 1 month. In many stroke survivors, this is a feasible approach and they will be potentially protected from recurrent stroke by anticoagulation treatment.Trial registration number NCT03301662

Prevalence and genotype distribution of cervical human papilomavirus infection in the pre-vaccination era: a population-based study in the Canary Islands

Objective National Spanish studies show that prevalence of cervical human papillomavirus (HPV) infection in the female population is increasingly frequent, with an overall estimate of 14% in women aged 18–65 years. The objective of this study is to know the prevalence and distribution of HPV types in the female population of the Canary Islands prior to the introduction of HPV vaccines and to investigate the associated clinical and sociodemographic factors.Methods Based on the Primary Health Care database, a sample of adult women (aged 18–65 years) of Gran Canaria (GC) and Tenerife (TF) stratified into nine age groups was carried out between 2002 and 2007. Women were contacted by postal letter and telephone call and were visited in their primary care centre. A clinical-epidemiological survey was completed and cervical samples were taken for cytological study and HPV detection. HPV prevalence and its 95% CI were estimated, and multivariate analyses were performed using logistic regression to identify factors associated with the infection.Results 6010 women participated in the study, 3847 from GC and 2163 from TF. The overall prevalence of HPV infection was 13.6% (CI 12.8%–14.5%) and 11.1% (CI 10.3%–11.9%) for high-risk types. The most frequent HPV type was 16 followed by types 51, 53, 31, 42 and 59. HPV types included in the nonavalent vaccine were detected in 54.1% of infected women. Factors associated with an increased risk of infection were: young ages (18–29 years), the number of sexual partners throughout life, not being married, being a smoker, and having had previous cervical lesions or genital warts.Conclusions It is confirmed that prevalence of HPV infection in the female population of the Canary Islands is high, but similar to that of Spain, HPV 16 being the most frequent genotype. The determinants of infection are consistent with those of other populations

VII Jornadas de Innovación Educativa de la Universidad de La Laguna: imaginar y comprender la innovación en la Universidad

The change of structure and process of the organizations of the current society has generated a great impact in the new way of working. Work teams coordination ensures that a team functions as a unitary whole; is identified as a key process to understand work team effectiveness. This paper presents a brief introduction of the recent research on Work teams in organizations and raises relevant issues about their implications for Pedagogy studies. This paper aims, first, to analyze the potential of team based organizations. And secondly, to examine the effects in pedagogy studies. Coordination is a process that involves the use of strategies and patterns of behavior aimed to integrate actions, knowledge and goals of interdependent members. The tasks have increased its difficulty, doing that individual resolution is very difficult or impossibleUniversidad de La Lagun
