    Sobre la presencia de Teucrium pumilum y Teucrium libanitis (Lamiaceae) en la provincia de Valencia

    Get PDF
    Teucrium pumilum y T. libanitis son dos especies que han sido citadas como presentes en la provincia de Valencia desde mediados del siglo XX, para los yesos que afloran en la comarca del Valle de Ayora-Cofrentes. El an谩lisis de las etiquetas de los pliegos de los herbarios no es concluyente; ning煤n pliego testigo certificar铆a la presencia de estas especies. La determinaci贸n de visu por parte de Rivas Goday, y su inclusi贸n en una tabla de inventarios fitosociol贸gica, son el 煤nico fundamento de su existencia en la zona en alg煤n momento determinado de la reciente historia bot谩nica espa帽ola. Adem谩s, para T. pumilum, el pliego de herbario que tradicionalmente se ha asignado a la cita valenciana se trata de una confusi贸n en la determinaci贸n por parte de algunos autores con su cong茅nere T. carolipaui, siendo imposible al mismo tiempo asignar una localidad geogr谩fica concreta a este material. Abstract. About the presence of Teucrium pumilum and Teucrium libanitis (Lamiaceae) in the Valencian province, Spain.- Teucrium pumilum and T. libanitis have been cited from Valencia province (Spain) since the middle of the XXth Century from the gypsic soils in the Valle de Ayora-Cofrentes shire. The analysis of specimens and labels is not conclusive; no specimen would certify the presence of any of these taxa. The field identification and their inclusion in a phyotosociological table (relev茅) by Rivas Goday are the only basis of their presence in the territory in a particular moment of the recent Spanish botanical history. Additionally, the unique herbarium specimen from Valencia, impossible to assign a concrete geographic locality, which was traditionally assigned to T. pumilum by some authors, is actually its congeneric T. carolipaui. Resum. Sobre la pres猫ncia de Teucrium pumilum i Teucrium libanitis (Lamiaceae) a la prov铆ncia de Val猫ncia.- Teucrium pumilum i T. libanitis s贸n dues esp猫cies que han estat citades com a presents a la prov铆ncia de Val猫ncia des de mitjans del segle XX, sobre els guixos que afloren a la comarca de la Vall d'Aiora-Cofrents. L'an脿lisi de les etiquetes dels plecs dels herbaris no 茅s concloent; cap plec testimoni certificaria la pres猫ncia d'aquestes esp猫cies. La determinaci贸 de visu per part de Rivas Goday, i la seva inclusi贸 en una taula d'inventaris fitosociol貌gica, s贸n l'煤nic fonament de la seva exist猫ncia a la zona en un moment determinat de la recent hist貌ria bot脿nica espanyola. A m茅s, per a T. pumilum, el plec d'herbari que tradicionalment s' ha assignat a la cita valenciana es tracta d'una confusi贸 en la determinaci贸 per part d'alguns autors amb el seu cong猫nere T. carolipaui, essent impossible al mateix temps assignar una localitat geogr脿fica concreta a aquest material

    Anti-tumour necrosis factor discontinuation in inflammatory bowel disease patients in remission: study protocol of a prospective, multicentre, randomized clinical trial

    Get PDF
    Background: Patients with inflammatory bowel disease who achieve remission with anti-tumour necrosis factor (anti-TNF) drugs may have treatment withdrawn due to safety concerns and cost considerations, but there is a lack of prospective, controlled data investigating this strategy. The primary study aim is to compare the rates of clinical remission at 1?year in patients who discontinue anti-TNF treatment versus those who continue treatment. Methods: This is an ongoing, prospective, double-blind, multicentre, randomized, placebo-controlled study in patients with Crohn?s disease or ulcerative colitis who have achieved clinical remission for ?6?months with an anti-TNF treatment and an immunosuppressant. Patients are being randomized 1:1 to discontinue anti-TNF therapy or continue therapy. Randomization stratifies patients by the type of inflammatory bowel disease and drug (infliximab versus adalimumab) at study inclusion. The primary endpoint of the study is sustained clinical remission at 1?year. Other endpoints include endoscopic and radiological activity, patient-reported outcomes (quality of life, work productivity), safety and predictive factors for relapse. The required sample size is 194 patients. In addition to the main analysis (discontinuation versus continuation), subanalyses will include stratification by type of inflammatory bowel disease, phenotype and previous treatment. Biological samples will be obtained to identify factors predictive of relapse after treatment withdrawal. Results: Enrolment began in 2016, and the study is expected to end in 2020. Conclusions: This study will contribute prospective, controlled data on outcomes and predictors of relapse in patients with inflammatory bowel disease after withdrawal of anti-TNF agents following achievement of clinical remission. Clinical trial reference number: EudraCT 2015-001410-1

    Gysophila hispanica Willk. is an iberian-levantine endemism with optimum in the Maestracensis sector (Castillan-Maestrazgo-Manchego province) and the province of Aragon, which is generally considered a gysum soil element. Analysis of the characteristics of the soils of the locations studied shows a wide edaphic spectrum and indicates that it belongs to halo(gypso)ni trophile taxa
