Hallazgos audiológicos en niños con mucopolisacaridosis tipos i - iv

2017

Resumen Objetivo Revision y descripcion de la afectacion otoaudiologica en el seguimiento de 23 ninos con diagnostico de mucopolisacaridosis (MPS) tipo  I , II , III y IV . Metodos Estudio retrospectivo de los hallazgos clinicos, audiologicos y tratamiento (medico y/o quirurgico) de 23 ninos con diagnostico de MPS tipo  I , II , III o IV en seguimiento en un hospital terciario entre 1997 y 2015. Resultados Seis casos de MPS  I , 8 de MPS  II , 4 de MPS  III y 5 de MPS  IV fueron revisados. Al inicio del seguimiento el 71,2% de los pacientes presentaban otitis media serosa (OMS) y el 54% de los casos presentaban algun tipo de hipoacusia. El comportamiento de la hipoacusia fue fluctuante en c…

Blastocystis sp., an emerging parasite with controversial pathogenicity. Should all human cases be treated?

Neither Diplectanum nor specific: a dramatic twist to the taxonomic framework of Diplectanum (Monogenea: Diplectanidae).

2019

The taxonomy of the genus Diplectanum has been exclusively based on morphological features, with 28 nominal species parasitic on perciform fishes recognised. We used molecular data, to our knowledge for the first time, to evaluate the taxonomic framework of Diplectanum, infer the relationships amongst species attributed to this genus, re-assess the degree of host specificity and explore the population genetic structure of Diplectanum spp. parasitising Mediterranean sciaenids, which are potential target fish species for aquaculture diversification in the region. A minimum of 10 specimens of Diplectanum spp. were sequenced per host species (Argyrosomus regius, Sciaena umbra, Umbrina canariens…

The protein and microRNA cargo of extracellular vesicles from parasitic helminths – current status and research priorities

2020

Helminth parasites have a remarkable ability to persist within their mammalian hosts, which is largely due to their secretion of molecules with immunomodulatory properties. Although the soluble components of helminth secretions have been extensively studied, the discovery that helminths release extracellular vesicles (EVs) has added further complexity to the host-parasite interaction. Whilst several studies have begun to characterise the molecules carried by helminth EVs, work aimed at investigating their biological functions has been hindered by a lack of helminth-specific EV markers. To begin to address this, we summarised helminth EV literature to date. With a focus on the protein and mi…

Eawag-Soil in enviPath: a new resource for exploring regulatory pesticide soil biodegradation pathways and half-life data.

2017

Developing models for the prediction of microbial biotransformation pathways and half-lives of trace organic contaminants in different environments requires as training data easily accessible and sufficiently large collections of respective biotransformation data that are annotated with metadata on study conditions. Here, we present the Eawag-Soil package, a public database that has been developed to contain all freely accessible regulatory data on pesticide degradation in laboratory soil simulation studies for pesticides registered in the EU (282 degradation pathways, 1535 reactions, 1619 compounds and 4716 biotransformation half-life values with corresponding metadata on study conditions)…

Decline in the incidence of colorectal cancer and the associated mortality in young Italian adults

2020

Objective The incidence of colorectal cancer (CRC) declines among subjects aged 50 years and above. An opposite trend appears among younger adults. In Europe, data on CRC incidence among younger adults are lacking. We therefore aimed to analyse European trends in CRC incidence and mortality in subjects younger than 50 years. Design Data on age-related CRC incidence and mortality between 1990 and 2016 were retrieved from national and regional cancer registries. Trends were analysed by Joinpoint regression and expressed as annual percent change. Results We retrieved data on 143.7 million people aged 20–49 years from 20 European countries. Of them, 187 918 (0.13%) were diagnosed with CRC. On a…

Monitoring B-cell repopulation after depletion therapy in neurologic patients.

2017

ObjectiveTo determine the factors that influence B-cell repopulation after B-cell depletion therapy in neurologic patients and derive recommendations for monitoring and dosing of patients.MethodsIn this study, we determined the association of body surface area (BSA; calculated by body weight and height with the Dubois formula), sex, pretreatment therapy, age, CSF data, and white blood cell counts with the risk and timing of B-cell repopulation, defined as 1% CD19+ cells (of total lymphocytes), following 87 B cell–depleting anti-CD20 treatment cycles of 45 neurologic patients (28 women; mean age ± SD, 44.5 ± 15.0 years).ResultsPatients with a larger BSA had a higher probability to reach 1% C…

Succinate receptor mediates intestinal inflammation and fibrosis.

2018

Succinate, an intermediate of the tricarboxylic acid cycle, is accumulated in inflamed areas and its signaling through succinate receptor (SUCNR1) regulates immune function. We analyze SUCNR1 expression in the intestine of Crohn's disease patients and its role in murine intestinal inflammation and fibrosis. We show that both serum and intestinal succinate levels and SUCNR1 expression in intestinal surgical resections were higher in CD patients than in controls. SUCNR1 co-localized with CD86, CD206, and alpha-SMA(+) cells in human intestine and we found a positive and significant correlation between SUCNR1 and alpha-SMA expression. In human isolated fibroblasts from CD patients SUCNR1 expres…

Fungal DNA is present in tissue specimens of patients with chronic rhinosinusitis.

2004

Background It has been postulated that fungal organisms might represent the immunologic target initiating and maintaining the disease process in patients with chronic rhinosinusitis (CRS). The presence of fungi in nasal mucus has been established by different groups, but so far it has not been shown how the immune system could even recognize such extramucosal—extracorporal—fungal targets. The aim of this study was to determine whether fungal DNA is present in tissue specimens taken from patients with polypoid CRS. Methods Twenty-seven surgical specimens were collected from patients suffering from CRS. Fifteen surgical specimens from healthy ethmoidal mucosa served as controls. A second set …
