The occurrence of Echinorhynchus salmonis Müller, 1784 in benthic amphipods in the Baltic Sea
2015
The acanthocephalan Echinorhynchus salmonis Muller, 1784 is a common parasite of salmonid fish, but it has rarely been reported from an intermediate host. Samples of benthic amphipods, Monoporeia affinis (Lindstrom), were taken from multiple, deep sites (usually below 70 m) in the Gulf of Bothnia over the course of more than a decade and examined for acanthocephalans. Overall, only 0.44% of 23 296 amphipods were infected, all with just a single worm. This prevalence is consistent with several previous reports of acanthocephalans in deep-water, benthic amphipods, but it appears low compared to that often reported for acanthocephalan species infecting littoral amphipods. Parasite occurrence d…
CARCINOSARCOMA ARISING IN A DERMOID CYST OF OVARY: A CASE REPORT
2005
BACKGROUND: Transformation of a cystic benign teratoma of the ovary into a "carcinosarcoma" has very rarely been reported and its histogenetic origin is still debated. CASE PRESENTATION: A case of carcinosarcoma arising from a dermoid cyst is reported. The tumor showed cystic areas delimited by normal squamous epithelium, with transitional areas through dysplastic epithelium to "in situ" and infiltrating squamous cell carcinoma (SCC). The sarcomatous component showed compact tissue composed of round cells concentrically arranged around small vessels, spindle, and pleomorphic cells with a high nuclear-cytoplasmic ratio. Positive staining for vimentin, alpha smooth muscle actin and CD10, as w…
Performance of existing definitions and tests for the diagnosis of invasive fungal diseases other than invasive candidiasis and invasive aspergillosi…

The first step of the project was the conduction of separated systematic reviews of the characteristics and applicability to critically ill, adult patients outside classical populations at ri…
Parasitación intestinal por unicelulares eucariotas en una población con obesidad mórbida: implicaciones clínico-metabólicas
2022
La obesidad es una enfermedad grave y multidimensional que, en la actualidad, ha alcanzado dimensiones pandémicas. Muchos son los mecanismos fisiopatológicos propuestos para intentar explicar el marcado aumento de su incidencia, y que se han orientado a hallar nuevas dianas terapéuticas con las que combatirla. Clásicamente se han señalado los factores ambientales propios del estilo de vida occidental (como la alimentación hipercalórica y el sedentarismo) como relevantes en el desarrollo de esta enfermedad; sin embargo, nuevas evidencias apuntan hacia que también podrían jugar un papel importante elementos infecciosos del medio, con repercusiones tanto perjudiciales como protectoras sobre el…
Effect of a cyanobacterial diet on the competition between rotifers: a case study in Lake Albufera of Valencia, Spain
2019
espanolBrachionus havanaensis se distribuye predominantemente en las regiones Neartica y Neotropical. Ahora se encuentra incluso en las regiones Paleartica y Oriental. Durante el verano de 2015, encontramos altas densidades (> 500 ind./l) de esta especie y bajas abundancias de Brachionus angularis en la laguna de la Albufera, donde la cianobacteria (Microcystis aeruginosa) fue dominante en la comunidad de fitoplancton. Nuestra hipotesis fue que la cianobacteria era toxica para B. angularis pero no para B. havanaensis, por lo que este ultimo superaria al primero en presencia de dicha cianobacteria. Para probar la hipotesis, realizamos experimentos de competencia entre estas dos especies de r…
PCOS Phenotypes: Impact on Fertility
2018
Polycystic ovary syndrome (PCOS) is characterised by an extreme heterogeneity and at least four main phenotypes may be distinguished. In referred population, anovulatory hyperandrogenic phenotype (classic PCOS or phenotypes A and B) is by far the most common phenotype and presents the most severe endocrine and metabolic alterations. Ovulatory PCOS and normoandrogenic phenotype represent a mild form of PCOS that is more common in general population and/or (normoandrogenic) in some particular ethnic group. During their life, because of changes in lifestyle or because of spontaneous changes in ovarian and adrenal androgen secretion that occur during late reproductive age, patients may move fro…
The efficacy and safety of nutrient supplements in the treatment of mental disorders: a meta‐review of meta‐analyses of randomized controlled trials
2019
The role of nutrition in mental health is becoming increasingly acknowledged. Along with dietary intake, nutrition can also be obtained from "nutrient supplements", such as polyunsaturated fatty acids (PUFAs), vitamins, minerals, antioxidants, amino acids and pre/probiotic supplements. Recently, a large number of meta-analyses have emerged examining nutrient supplements in the treatment of mental disorders. To produce a meta-review of this top-tier evidence, we identified, synthesized and appraised all meta-analyses of randomized controlled trials (RCTs) reporting on the efficacy and safety of nutrient supplements in common and severe mental disorders. Our systematic search identified 33 me…
