    Hard on the heels of the Lepton-Photon Symposium at Stanford in August came the International Europhysics Conference on High Energy Physics in Madrid from 6-13 September. With the two meetings held so close together, there was much overlap in the physics reported, although some teams were able to use the extra month to present new results. A notable example was the Mark II team working at Stanford's SLC linear collider, who presented new limits on the number of allowed neutrinos.The Madrid meeting attracted about 600 participants from all over the world. An initial three days of parallel sessions followed by four days of plenary talks could cover the field in depth and in breadth.

    This ASTER image was acquired on July 5, 2000 and covers an area of 25 by 24 km over Madrid, Spain. A historic capital city, Madrid is renowned for its unique charm and its exhilarating cultural life. In the 10th century, a Moorish fortress called Magerit was first built on the site, a plateau 656 meters (2,150 feet) above sea level. Spanish Christians seized the city a century later, although Madrid remained relatively unimportant until 1561. It was then that the Spanish king Philip II chose it as the national capital, largely because of its geographic location in the very heart of the country. Some historic structures from this and later periods still grace the narrow streets of the old section of Madrid, although the Spanish Civil War exacted a heavy toll on the city. The image is located at 40.4 degrees north latitude and 3.7 degrees west longitude. The U.S. science team is located at NASA's Jet Propulsion Laboratory, Pasadena, Calif. The Terra mission is part of NASA's Science Mission Directorate.

    The Comunidad Autonoma de Madrid (Autonomous Community of Madrid, in the following Madrid Region), is a region located at the geographical centre of the Iberian Peninsula. Its area is 8.028 km{sup 2}, and its population about five million people. The Department of Economy and Technological Innovation of the Madrid Region, together with some organizations dealing on energy saving and other research institutions have elaborated an Energy Plan for the 2004-12 period. As a part of this work, the Fluid Mechanics Laboratory of the Superior Technical School of Industrial Engineers of the Polytechnic University of Madrid has carried out the assessment of the wind energy resources [Crespo A, Migoya E, Gomez Elvira R. La energia eolica en Madrid. Potencialidad y prospectiva. Plan energetico de la Comunidad de Madrid, 2004-2012. Madrid: Comunidad Autonoma de Madrid; 2004]; using for this task the WAsP program (Wind Atlas Analysis and Application Program), and the own codes, UPMORO (code to study orography effects) and UPMPARK (code to study wake effects in wind parks). Different kinds of data have been collected about climate, topography, roughness of the land, environmentally protected areas, town and village distribution, population density, main facilities and electric power supply. The Spanish National Meteorological Institute has nine wind measurement stations in the region, but only four of them have good and reliable temporary wind data, with time measurement periods that are long enough to provide representative correlations among stations. The Observed Wind Climates of the valid meteorological stations have been made. The Wind Atlas and the resource grid have been calculated, especially in the high wind resource areas, selecting appropriate measurements stations and using criteria based on proximity, similarity and ruggedness index. Some areas cannot be used as a wind energy resource mainly because they have environmental regulation or, in some cases, are very close

  17. Assessing idiopathic pulmonary fibrosis (IPF) with bronchoscopic OCT (Conference Presentation)

    Hariri, Lida P.; Adams, David C.; Colby, Thomas V.; Tager, Andrew M.; Suter, Melissa J.

    2016-03-01

    Idiopathic pulmonary fibrosis (IPF) is a progressive, fatal form of fibrotic lung disease, with a 3 year survival rate of 50%. Diagnostic certainty of IPF is essential to determine the most effective therapy for patients, but often requires surgery to resect lung tissue and look for microscopic honeycombing not seen on chest computed tomography (CT). Unfortunately, surgical lung resection has high risks of associated morbidity and mortality in this patient population. We aim to determine whether bronchoscopic optical coherence tomography (OCT) can serve as a novel, low-risk paradigm for in vivo IPF diagnosis without surgery or tissue removal. OCT provides rapid 3D visualization of large tissue volumes with microscopic resolutions well beyond the capabilities of CT. We have designed bronchoscopic OCT catheters to effectively and safely access the peripheral lung, and conducted in vivo peripheral lung imaging in patients, including those with pulmonary fibrosis. We utilized these OCT catheters to perform bronchoscopic imaging in lung tissue from patients with pulmonary fibrosis to determine if bronchoscopic OCT could successfully visualize features of IPF through the peripheral airways. OCT was able to visualize characteristic features of IPF through the airway, including microscopic honeycombing (< 1 mm diameter) not visible by CT, dense peripheral fibrosis, and spatial disease heterogeneity. These findings support the potential of bronchoscopic OCT as a minimally-invasive method for in vivo IPF diagnosis. However, future clinical studies are needed to validate these findings.

    Full Text Available Una tasa de mortalidad por debajo del promedio nacional español ha hecho que Madrid se gane la reputación de lugar sano para vivir y para morir; aquí, se examina esta reputación usando datos empíricos recientes. Las estadísticas de población demuestran cómo durante los últimos sesenta años, Madrid ha mostrado un mayor crecimiento durante los años 60 y 70, un período de desarrollo económico; desde entonces el nivel de salud se ha deteriorado. La prosperidad económica por sí misma no asegura unas condiciones mejores de la salud, a causa de las desigualdades y desequilibrios en la distribución y el control de los recursos sanitarios. Los datos sobre tipos de enfermedades, causas de hospitalización y periodos de estancia, embarazos, muertes accidentales, y nacimientos, matrimonios, y los índices de mortalidad para Madrid se presentan, y son comparados con los de Barcelona y los de España en su totalidad. De igual modo se sugieren otras áreas de investigación.

    Full Text Available The public transport, as we know it today, originates from the end of the 18 th and beginning of the 19th Centuries. Initially a privilege for the aristocratic and bourgeoisie classes, public transport saw a surge in development once communication between Madrid and others distant urban centers became a necessity that demanded a more economical and accessible transport system. The increase of these services, along with the diversification of the means of transportation, quickly caused congestion problems at transfer points. Throughout the last century, these same problems have been confronted with a variety of diverse strategies and solutions. All in all, the history of intermodality in Madrid tells the story of an evolution that has allowed the urban web to unite all of its branches extending from the main gates that are now being converted the interchanges in relation with the city. From its creation in 1985, the CRTM (transport authority of Madrid, considered the intermodality to be a main priority within the following different fields of action: infrastructure, ticketing and whole image and information. Within the interchanges is where the integration efforts of the different transport modes best become a reality. In essence, interchanges play the same role in today`s cities as the gates in the walls of a centuries-old medieval city. At this moment, interchanges are the gates to the cities of the 21st Century. Resumen El transporte público, tal como lo conocemos hoy, se origina a finales del siglo XVIII y principios del XIX. Inicialmente fue un privilegio para las clases aristocráticas y burguesas. El transporte público vio un aumento en el desarrollo una vez que la comunicación entre Madrid y otros centros urbanos distantes se convirtió en una necesidad que exigía un sistema de transporte más económico y accesible. El aumento de estos servicios, junto con la diversificación de los medios de transporte, causó rápidamente problemas

    2015-01-01

    Purpose of Review Upper airway disease engenders significant morbidity for patients with cystic fibrosis and is increasingly recognized as having a much greater role in pulmonary outcomes and quality of life than originally believed. Widespread disparate therapeutic strategies for cystic fibrosis chronic rhinosinusitis underscore the absence of a standardized treatment paradigm. This review outlines the most recent evidence-based trends in the management of upper airway disease in cystic fibrosis. Recent Findings The unified airway theory proposes that the sinuses are a focus of initial bacterial colonization which seeds the lower airway and may play a large role in maintaining lung infections. Mounting evidence suggests more aggressive treatment of the sinuses may confer significant improvement in pulmonary disease and quality of life outcomes in cystic fibrosis patients. However, there is a lack of high-level evidence regarding medical and surgical management of cystic fibrosis chronic rhinosinusitis that makes generalizations difficult. Summary Well designed clinical trials with long-term follow-up concerning medical and surgical interventions for cystic fibrosis sinus disease are required to establish standardized treatment protocols, but increased interest in the sinuses as a bacterial reservoir for pulmonary infections has generated considerable attention.

    Bonifant, Catherine M; Shevill, Elizabeth; Chang, Anne B

    2014-05-14

    People with cystic fibrosis and pancreatic insufficiency are at risk of fat soluble vitamin deficiency as these vitamins (A, D, E and K) are co-absorbed with fat. Thus, some cystic fibrosis centres routinely administer these vitamins as supplements but the centres vary in their approach of addressing the possible development of deficiencies in these vitamins. Vitamin A deficiency causes predominantly eye and skin problems while supplementation of vitamin A to excessive levels may cause harm to the respiratory and skeletal systems in children. Thus a systematic review on vitamin A supplementation in people with cystic fibrosis would help guide clinical practice. To determine if vitamin A supplementation in children and adults with cystic fibrosis:1. reduces the frequency of vitamin A deficiency disorders;2. improves general and respiratory health;3. increases the frequency of vitamin A toxicity. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register which comprises of references identified from comprehensive electronic database searches and handsearches of relevant journals and abstract books of conference proceedings.Date of the most recent search of the Group's Cystic Fibrosis Trials Register: 07 April 2014. All randomised or quasi-randomised controlled trials comparing all preparations of oral vitamin A used as a supplement compared to either no supplementation (or placebo) at any dose and for any duration, in children or adults with cystic fibrosis (defined by sweat tests or genetic testing) with and without pancreatic insufficiency. No relevant studies for inclusion were identified in the search. No studies were included in this review. As there were no randomised or quasi-randomised controlled trials identified, we cannot draw any conclusions on the benefits (or otherwise) of regular administration of vitamin A in people with cystic fibrosis. Until further data are available, country or region specific guidelines on the use of

    Hidalgo, R.; Sanchez, J.; Ungemach, P.

    2009-07-01

    The Madrid Basin geothermal potential was evidenced in 1980 thanks to an oil exploration well drilled by Shell-Campsa which showed temperatures of 88 degree centigrade and 150 degree centigrade at 1,700 mts and 3,400 mts depth respectively. The low enthalpy geothermal reservoir could be further assessed by four exploratory wells the first one, Pradillo (originals Shell-Campsa oil well), two drilled by ADARO and IGME (Geological survey of Spain) in San Sebastian de los Reyes and Tres Cantos respectively. The latest well, Geomadrid 1, was drilled in 1990 by the Madrid Regional government. The afore mentioned wells have identified a dependable geothermal resource, hosted in a tertiary, clastic, consolidated sandstone reservoir consisting of a thick multilayered sequence (200-800m), with temperatures ranging from 70 degree centigrade to 90 degree centigrade and depths of 1,500 to 2,150 m., overlying a Mesozoic sequence, suitable to be exploited for thermal uses in several district heating grids around Madrid in areas displaying adequate heat loads. A medium temperature reservoir was also identified at the contact between Mesozoic Cretaceous limestones and fractured basement granites at 3,400mts depth, with measured temperatures of 156 degree centigrade, that could be developed and exploited in view of a combined power and heat production (CPH) within the Madrid suburban areas.

    The development and installation of components of a U.S. National Seismic Network (USNSN) in the eastern United States provides the basis for long term monitoring of eastern earthquakes. While the broad geographical extent of this network provides a uniform monitoring threshold for the purpose of identifying and locating earthquakes and while it will provide excellent data for defining some seismic source parameters for larger earthquakes through the use of waveform modeling techniques, such as depth and focal mechanism, by itself it will not be able to define the scaling of high frequency ground motions since it will not focus on any of the major seismic zones in the eastern U.S. Realizing this need and making use of a one time availability of funds for studying New Madrid earthquakes, Saint Louis University and Memphis State University successfully competed for funding in a special USGS RFP for New Madrid studies. The purpose of the proposal is to upgrade the present seismic networks run by these institutions in order to focus on defining the seismotectonics and ground motion scaling in the New Madrid Seismic Zone. The proposed network is designed both to complement the U.S. National Seismic Network and to make use of the capabilities of the communication links of that network

    Achromobacter xylosoxidans is an emerging pathogen in cystic fibrosis (CF). Although the rate of colonization by this microorganism is variable, prevalence is increasing in CF units. A microbiological/clinical study was conducted on of adult CF patients harboring A. xylosoxidans. Identification and susceptibility testing were performed using MicroScan (Siemens). Decline in lung function was assessed using the variable, annual percentage loss of FEV1 (forced expiratory volume in 1s). A. xylosoxidans was isolated in 18 (19.8%) of 91 patients over a 14-year period. Mean age was 26.6 years (18-39 years). Nine patients (9.8%) were chronically colonized. Piperacillin/tazobactam and imipenem were the most active antibiotics. Mean annual decline in lung function in chronically colonized patients was 2.49%. A. xylosoxidans is a major pathogen in CF. A decreased lung function was observed among patients who were chronically colonized by A. xylosoxidans. Antibiotic therapy should be started early in order to prevent chronic colonization by this microorganism.

    Liver fibrosis is a reversible wound-healing response to chronic hepatic injuries. Activation of hepatic stellate cells (HSCs) plays a pivotal role in the development of hepatic fibrosis. The currently accepted mechanism for the resolution of liver fibrosis is the apoptosis and inactivation of activated HSCs. Protein tyrosine phosphatase 1B (PTP1B), a prototype of non-receptor protein tyrosine phosphatase, is proved to be a vital modulator in cardiac fibrogenesis. However, the precise role of PTP1B on liver fibrosis and HSC activation is still unclear. Our study showed that the expression of PTP1B was elevated in fibrotic liver but reduced after spontaneous recovery. Moreover, stimulation of HSC-T6 cells with transforming growth factor-β1 (TGF-β1) resulted in a dose/time-dependent increase of PTP1B mRNA and protein. Co-incubation of HSC-T6 cells with PTP1B-siRNA inhibited the cell proliferation and activation induced by TGF-β1. Additionally, both mRNA and protein of PTP1B were dramatically decreased in inactivated HSCs after treated with adipogenic differentiation mixture (MDI). Over-expression of PTP1B hindered the inactivation of HSC-T6 cells induced by MDI. These observations revealed a regulatory role of PTP1B in liver fibrosis and implied PTP1B as a potential therapeutic target. - Highlights: • The expression of PTP1B in the fibrotic livers and recovery livers • The expression of PTP1B in activated and inactivated HSCs • Blockade of PTP1B inhibited the TGF-β1-induced proliferation and activation of HSCs. • Over-expression of PTP1B abolished the inactivation of HSCs induced by MDI.

    A 15-year pollen count was performed in the atmosphere of Madrid, Spain, to determine the months in which the highest concentrations of allergenic pollens occur. Pollen counts were done with a Burkard spore trap (Burkard Manufacturing, Rickmansworth, Herst., U.K.). The results were subsequently compared with results of skin tests in patients with pollinosis born and living in and around Madrid. The highest airborne presence (percent of total yearly pollen counts, mean of counts from 1979 to 1993) was for Quercus spp. (17%); followed by Platanus spp. (15%), Poaceae (15%), Cupressaceae (11%), Olea spp. (9%), Pinus spp. (7%), Populus spp. (4%), and Plantago spp. (4%). The most predominant pollens from January to April are tree pollens (Cupressaceae, Alnus, Fraxinus, Ulmus, Populus, Platanus, and Morus), although these are also abudant in May and June (Quercus, Olea, and Pinus spp.). The grass pollination period shows a double curve: the first peak occurs from February to April (8% of yearly grasses), and the second peak occurs from May to July (90% of yearly grasses). Among allergenically significant weeds, the most notable is Plantago; in contrast, Rumex, Urticaceae, Cheno-Amaranthaceae, and Artemisia spp. have very low concentrations (arizonica (20%). The population of Madrid is exposed to high concentrations of allergenic pollen from February to July, although the most intense period is from May to June. Grass pollens are the most important cause of pollinosis in this area.

    The New Madrid Seismotectonic Study is a coordinated program of geological, geophysical, and seismological investigations of the area within a 200-mile radius of New Madrid, Missouri. The study is designed to define the structural setting and tectonic history of the area in order to realistically evaluate earthquake risks in the siting of nuclear facilities. Fiscal year 1982 included geological and geophysical studies aimed at better definition of the east-west trending fault systems - the Rough Creek and Cottage Grove systems - and the northwest-trending Ste. Genevieve faulting. A prime objective was to determine the nature and history of faulting and to establish the relationship with that faulting and the northeast-trending faults of the Wabash Valley and New Madrid areas. 27 references, 61 figures

  1. The Social ecology of Madrid: Stratification in comparative perspective.

    Abrahamson, M; Johnson, P

    1974-08-01

    This paper examines the characteristics of residential zones in Madrid, Spain. The primary difference between zones is found to lie in a new bourgeoisie life-style dimension. Working women are found to be the best indicator of this dimension, which also involves servants, natives of Madrid and high degrees of literacy. Fertility-related considerations, however, are unrelated to working women, and this is explained as due to the availability of domestic help and "women-oriented" working arrangements. Fertility and socioeconomic status are found to be interrelated and constitute a second dimension of residential segregation. In conclusion, Madrid is examined in relation to both more and less industrialized cities, leading to a further modification of social area theory contentions concerning the ecology of stratification in developing cities.

    Poor nutrition occurs frequently in people with cystic fibrosis and is associated with other adverse outcomes. Oral calorie supplements are used to increase total daily calorie intake and improve weight gain. However, they are expensive and there are concerns they may reduce the amount of food eaten and not improve overall energy intake. This is an update of a previously published review. To establish whether in people with cystic fibrosis, oral calorie supplements: increase daily calorie intake; and improve overall nutritional intake, nutritional indices, lung function, survival and quality of life. To assess adverse effects associated with using these supplements. We searched the Cochrane Cystic Fibrosis Trials Register comprising references from comprehensive electronic database searches, handsearches of relevant journals and abstract books of conference proceedings. We contacted companies marketing oral calorie supplements.Last search: 18 October 2016. Randomised or quasi-randomised controlled trials comparing use of oral calorie supplements for at least one month to increase calorie intake with no specific intervention or additional nutritional advice in people with cystic fibrosis. We independently selected the included trials, assessed risk of bias and extracted data. We contacted the authors of included trials and obtained additional information for two trials. We identified 21 trials and included three, reporting results from 131 participants lasting between three months and one year. Two trials compared supplements to additional nutritional advice and one to no intervention. Two of the included trials recruited only children. In one trial the risk of bias was low across all domains, in a second trial the risk of bias was largely unclear and in the third mainly low. Blinding of participants was unclear in two of the trials. Also, in one trial the clinical condition of groups appeared to be unevenly balanced at baseline and in another trial there were

  6. Earthquake Hazard in the New Madrid Seismic Zone Remains a Concern

    There is broad agreement in the scientific community that a continuing concern exists for a major destructive earthquake in the New Madrid seismic zone. Many structures in Memphis, Tenn., St. Louis, Mo., and other communities in the central Mississippi River Valley region are vulnerable and at risk from severe ground shaking. This assessment is based on decades of research on New Madrid earthquakes and related phenomena by dozens of Federal, university, State, and consulting earth scientists. Considerable interest has developed recently from media reports that the New Madrid seismic zone may be shutting down. These reports stem from published research using global positioning system (GPS) instruments with results of geodetic measurements of strain in the Earth's crust. Because of a lack of measurable strain at the surface in some areas of the seismic zone over the past 14 years, arguments have been advanced that there is no buildup of stress at depth within the New Madrid seismic zone and that the zone may no longer pose a significant hazard. As part of the consensus-building process used to develop the national seismic hazard maps, the U.S. Geological Survey (USGS) convened a workshop of experts in 2006 to evaluate the latest findings in earthquake hazards in the Eastern United States. These experts considered the GPS data from New Madrid available at that time that also showed little to no ground movement at the surface. The experts did not find the GPS data to be a convincing reason to lower the assessment of earthquake hazard in the New Madrid region, especially in light of the many other types of data that are used to construct the hazard assessment, several of which are described here.

    2007-10-01

    Cystathionine beta synthase (CBS) is a crucial regulator of plasma concentrations of homocysteine. Severe hyperhomocysteinemia due to CBS deficiency confers diverse clinical manifestations, notably pulmonary thrombotic disease. However, the association between hyperhomocysteinemia and chronic obstructive pulmonary disease is not well understood. To investigate the role of hyperhomocysteinemia in lung injury and pulmonary fibrosis, we analyzed the lung of CBS-deficient mice, a murine model of severe hyperhomocysteinemia. The degree of lung injury was assessed by histologic examination. Analysis of profibrogenic factors was performed by real-time quantitative reverse transcription-polymerase chain reaction. CBS-deficient mice develop fibrosis and air space enlargement in the lung, concomitant with an enhanced expression of heme oxygenase-1, pro(alpha)1 collagen type I, transforming growth factor-beta1 and alpha-smooth muscle actin. However, lung fibrosis was found in the absence of increased inflammatory cell infiltrates as determined by histology, without changes in gene expression of proinflammatory cytokines TNFalpha and interleukin 6. The increased expression of alpha-smooth muscle actin and transforming growth factor-beta1 emphasizes the role of myofibroblasts differentiation in case of lung fibrosis due to CBS deficiency in mice.

    2015-01-01

    The emergence of neurology in Madrid between 1885 and 1939 had well-defined characteristics. On foundations laid by Cajal and Río-Hortega, pioneers combined clinical practice with cutting-edge neurohistology and neuropathology research. Luis Simarro, trained in Paris, taught many talented students including Gayarre, Achúcarro and Lafora. The untimely death of Nicolás Achúcarro curtailed his promising career, but he still completed the clinicopathological study of the first American case of Alzheimer's disease. On returning to Spain, he studied glial cells, including rod cells. Rodríguez Lafora described progressive myoclonus epilepsy and completed experimental studies of corpus callosum lesions and clinical and neuropathology studies of senile dementia. He fled to Mexico at the end of the Spanish Civil War (1936-1939). Sanchís Banús, a sterling clinical neurologist, described the first cluster of Huntington's disease in Spain, and he and Río-Hortega joined efforts to determine that pallidal degeneration underlies rigidity in advanced stages of the disease. Just after the war, Alberca Llorente eruditely described inflammatory diseases of the neuraxis. Manuel Peraita studied "the neurology of hunger" with data collected during the siege of Madrid. Dionisio Nieto, like many exiled intellectuals, settled in Mexico DF, where he taught neurohistological methods and neuropsychiatry in the tradition of the Madrid School of Neurology.

    This poster summarizes a few of the more significant facts about the series of large earthquakes that struck the New Madrid seismic zone of southeastern Missouri, northeastern Arkansas, and adjacent parts of Tennessee and Kentucky from December 1811 to February 1812. Three earthquakes in this sequence had a magnitude (M) of 7.0 or greater. The first earthquake occurred on December 16, 1811, at 2:15 a.m.; the second on January 23, 1812, at 9 a.m.; and the third on February 7, 1812, at 3:45 a.m. These three earthquakes were among the largest to strike North America since European settlement. The mainshocks were followed by many hundreds of aftershocks that occurred over the next decade. Many of the aftershocks were major earthquakes themselves. The area that was strongly shaken by the three main shocks was 2-3 times as large as the strongly shaken area of the 1964 M9.2 Alaskan earthquake and 10 times as large as that of the 1906 M7.8 San Francisco earthquake. Geologic studies show that the 1811-1812 sequence was not an isolated event in the New Madrid region. The 1811-1812 New Madrid earthquake sequence was preceded by at least two other similar sequences in about A.D. 1450 and A.D. 900. Research also indicates that other large earthquakes have occurred in the region surrounding the main New Madrid seismicity trends in the past 5,000 years or so.

    Dirofilaria immitis causes heartworm disease, a chronic and potentially fatal cardiopulmonary disease which mainly affects dogs and cats. It is present in most of Spain, due to favourable climatic factors. Madrid, located in the centre of the Iberian Peninsula, is the most highly populated city in the country. There is a lack of current data on canine heartworm and there are no published epidemiological data regarding feline heartworm in this region, therefore the aim of this study was to assess the prevalence and current distribution of canine and feline dirofilariosis in the province of Madrid. Serum samples from 1716 dogs and 531 cats, from animals living in the metropolitan area of Madrid and adjacent areas, were studied. All the samples, either from cats and dogs, were tested for circulating D. immitis antigens using a commercial immunochromatographic test kit. Furthermore, to establish the seroprevalence of heartworm infection in cats, serological techniques for anti-D. immitis and anti-Wolbachia antibody detection were used. Prevalence of D. immitis in the canine population of Madrid was 3%, showing an increase in comparison to previous data. The presence of heartworm in the city centre could be influenced by the presence of Urban Heat Islands, while the positive dogs from metropolitan and adjacent areas were mainly located under the influence of rivers. Regarding cats, 0.2% were positive to the antigens test and 7.3% were seropositive to both anti-D. immitis and Wolbachia surface protein antibodies, which demonstrate the presence of feline heartworm in Madrid. Seropositive cats were present in the same areas where positive dogs were found. Indoor/outdoor cats showed the highest seroprevalence whereas the lowest corresponded to indoor cats, demonstrating that prophylactic treatments should be carried out regardless of lifestyle. Infection was found in 2.2% of dogs and 6.7% of the cats < 1 year-old, which indicates that early preventive campaigns in puppies

    The construction of muon drift tube chambers (DT) has been carried out in four different european institutes: Aachen (Germany), CIEMAT-Madrid (Spain), Legnaro and Turin (Italy), all of them following similar procedures and quality tests. Each chamber is composed by three or two independent units called superlayers, with four layers of staggered drift cells each. The assembly of a superlayer is a succesive glueing of aluminium plates and I-beams with electrodes previously attached, forming a rectangular and gas-tight volume. These pictures illustrate the various processes of material preparation, construction, equipment and assembly of full chambers at CIEMAT (Madrid).

    Burkholderia cepacia complex have emerged as significant pathogens in cystic fibrosis (CF) patients due to the risk of cepacia syndrome and the innate multi-resistance of the microorganisms to antibiotics. The aim of this study was to describe the antimicrobial susceptibility profiles, the genotypes and subtypes of BCC, and the clinical evolution of CF patients with BCC. The lung function and Brasfield and Shwachman score were assessed in 12 patients. BCC were identified and susceptibility was studied by MicroScan (Siemens). Species and genospecies of BCC were confirmed by molecular methods in a Reference Centre (Majadahonda). BCC were identified in 12 of 70 patients (17.1%) over a ten year period. The mean age to colonization by BCC was 24.4 years (SD: 7.71). B. cenocepacia was isolated in 4 patients (33.3%), B. contaminans was isolated in 3 patients (25%), both B. vietnamiensis and B. stabilis were isolated in 2 patients (16.7%), and B. cepacia, B. multivorans and B. late were isolated in one patient (8.3%). Among the B. cenocepacia, subtype IIIa was identified in two strains, and subtype IIIb was identified in the other two strains. There was susceptibility to meropenem in 90% of BCC, 80% to cotrimoxazole, 60% to minocycline, 50% to ceftazidime, and 40% to levofloxacin. B. cenocepacia was the most prevalent species among the BCC isolated in CF adult patients, and subtypes IIIa and IIIb were identified in the 50% of the strains. Meropenem and cotrimoxazole showed the best activity. Copyright © 2012 Elsevier España, S.L. All rights reserved.

    Full Text Available The Madrid of Lope de Vega, Calderón de la Barca and other figures of Spain's Golden Age is also the Madrid of the fearsome Inquisition directed against the influx of Portuguese Jews and against native New Christians of Jewish background, often merchants whose work allowed them to circulate throughout Europe and North Africa. Eradication or true conversion were the only solutions proposed by the Holy Office. Since those conversos who fled Spain left no record dealing with their daily lives in Inquisitorial Madrid, the best source for obtaining such Information and for recreating the atmosphere of the era is the Holy Office itself. Accordingly, the author examines the reports written to the king by the civil servants and/or church officials charged with creating three spectacular autos de fe carried out in the Plaza Mayor: one in 1632 and two in 1680.

    El Madrid de Lope de Vega, Calderón de la Barca y otras figuras del Siglo de Oro español es también el Madrid del terror inquisitorial, dirigido contra los recién llegados judíos portugueses y los cristianos nuevos madrileños, de origen judío, muchos de ellos mercaderes cuyo trabajo les llevaba a viajar por toda Europa y el norte de África. El Santo Oficio no les permitía más opciones que la desaparición física o la conversión sincera. Como aquellos que huyeron del país no dejaron nada escrito sobre su vida cotidiana en este Madrid inquisitorial, la mejor fuente para obtener esta información y recrear el ambiente de la época es el Santo Oficio mismo. Por ello, la autora examina los informes dirigidos al Rey por los oficiales reales y/o inquisidores, encargados de la organización de tres espectaculares autos de fe que tuvieron lugar en la Plaza Mayor, uno en 1632 y dos en 1680.

    Physical exercise training may form an important part of regular care for people with cystic fibrosis. This is an update of a previously published review. To assess the effects of physical exercise training on exercise capacity by peak oxygen consumption, pulmonary function by forced expiratory volume in one second, health-related quality of life and further important patient-relevant outcomes in people with cystic fibrosis. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register which comprises references identified from comprehensive electronic database searches and handsearches of relevant journals and abstract books of conference proceedings.Date of the most recent search: 04 May 2017.We searched ongoing trials registers (clinicaltrials.gov and the WHO ICTRP). Date of most recent search: 10 August 2017. All randomised and quasi-randomised controlled clinical trials comparing exercise training of any type and a minimum duration of two weeks with conventional care (no training) in people with cystic fibrosis. Two authors independently selected studies for inclusion, assessed methodological quality and extracted data. The quality of the evidence was assessed using the GRADE system. Of the 83 studies identified, 15 studies which included 487 participants, met the inclusion criteria. The numbers in each study ranged from nine up to 72 participants; two studies were in adults, seven were in children and adolescents and six studies included all age ranges. Four studies of hospitalised participants lasted less than one month and 11 studies were outpatient-based, lasting between two months and three years. The studies included participants with a wide range of disease severity and employed differing levels of supervision with a mixture of types of training. There was also wide variation in the quality of the included studies.This systematic review shows very low- to low-quality evidence from both short- and long-term studies that in people

    Full Text Available The effect of delocalization on a national economy has been widely studied, however subnational delocalization remains as an unvisited field for researchers. This paper studies the effects of fragmentation and the subsequent localization outside or abroad on the level of industrial and services employment in Madrid region. We work with Madrid data from regional input-output tables and estimate a labour demand function using panel data. Our results show a significant and small negative effect on regional employment of intra-industrial inputs from the national economy and abroad, while imported inputs from other sectors and origins are complementary to employment, resulting in a positive net effect on employment. The increasing specialization in main activities and the use of external providers by firms have a positive impact on the employment of Madrid region.

    The Spanish Conference on e-Science Grid Computing and the EGEE-EELA Industrial Day (http://webrt.ciemat.es:8000/e-science/index.html) are the first edition of this open forum for the integration of Grid Technologies and its applications in the Spanish community. It has been organised by CIEMAT and CETA-CIEMAT, sponsored by IBM and HP and supported by the European Community through their funded projects EELA, EUChinaGrid and EUMedGrid. To all of them, the conference is very grateful. e-Science is the concept that defines those activities developed by using geographically distributed resources, which scientists (or whoever) can access through the Internet. However, commercial Internet does not fulfil resources such as calculus and massive storage -most frequently in demand in the field of e-Science- since they require high-speed networks devoted to research. These networks, alongside the collaborative work applications developed within them, are creating an ideal scenario for interaction among researchers. Thus, this technology that interconnects a huge variety of computers, information repositories, applications software and scientific tools will change the society in the next few years. The science, industry and services systems will benefit from his immense capacity of computation that will improve the quality of life and the well-being of citizens. The future generation of technologies, which will reach all of these areas in society, such as research, medicine, engineering, economy and entertainment will be based on integrated computers and networks, rendering a very high quality of services and applications through a friendly interface. The conference aims at becoming a liaison framework between Spanish and International developers and users of e-Science applications and at implementing these technologies in Spain. It intends to be a forum where the state of the art of different European projects on e- Science is shown, as well as developments in the research

    Epithelial-mesenchymal transition (EMT) describes the global process by which stationary epithelial cells undergo phenotypic changes, including loss of cell-cell adhesion and apical-basal polarity, and acquire mesenchymal characteristics which confer migratory capacity. EMT and its converse, MET (mesenchymal-to-epithelial transition), are integral stages of many physiologic processes, and as such are tightly coordinated by a host of molecular regulators. Converging lines of evidence have identified EMT as a component of cutaneous wound healing, during which otherwise stationary keratinocytes - the resident skin epithelial cells - migrate across the wound bed to restore the epidermal barrier. Moreover, EMT also plays a role in the development of scarring and fibrosis, as the matrix-producing myofibroblast arises from cells of epithelial lineage in response to injury but is pathologically sustained instead of undergoing MET or apoptosis. In this review, we summarize the role of EMT in physiologic repair and pathologic fibrosis of tissues and organs. We conclude that further investigation into the contribution of EMT to the impaired repair of fibrotic wounds may identify components of EMT signaling as common therapeutic targets for impaired healing in many tissues.

    ABSTRACT: The Metropolitan Greenbelt was defined by the 1963 Master Plan for the Madrid Metropolitan Area (MMA, following established international models of urban development, as the structural framework of the MMA, the principal open space within its network of open spaces and a public area of recreation and contact with nature for the residents of Madrid. However, it had become a reserve of land in which various alliances between the institutional authorities and the dominant social class, have been operating on the margin of the original plan, exposing a scarcity of legal and cultural resources for the safeguarding of common interests, and in which the geographical and natural characteristics of the territory itself have come to play an influential role in the functional specialization and spatial segregation of the MMA.

    Social impacts of pollutants from mobile sources are a key element in urban design and traffic planning. One of the most relevant impacts is health effects associated with high pollution periods. Madrid is a city that suffers chronic congestion levels and some periods of very stable atmospheric conditions; as a result, pollution levels exceed air quality standards for certain pollutants.This paper focuses on the social evaluation of transport-related emissions. A new methodology to evaluate those impacts in monetary terms has been designed and applied to Madrid. The method takes into account costs associated with losses in working time, mortality and human suffering; calculated using an impact pathway approach linked to CORINAIR emissions. This also allows the calculation of social costs associated with greenhouse gas impacts. As costs have been calculated individually by effect and mode of transport, they can be used to design pricing policies based on real social costs. This paper concludes that the health and social costs of transport-related air pollution in Madrid is 357 Meuro. In these circumstances, the recent public health tax applied in Madrid is clearly correct and sensible with a fair pricing policy on car use.

    To estimate the prevalence of hepatitis B virus (HBV) infection and vaccine-induced immunity in the region of Madrid, and to analyze their evolution over time. An observational, analytical, cross-sectional study was carried out in the population aged 16-80 years between 2008 and 2009. This was the last of four seroprevalence surveys in the region of Madrid. The prevalence of HBV infection and vaccine-induced immunity was estimated using multivariate logistic models and were compared with the prevalences in the 1989, 1993 and 1999 surveys. In the population aged 16-80 years, the prevalence of HBV infection was 11.0% (95% CI: 9.8-12.3) and that of chronic infection was 0.7% (95% CI: 0.5-1.1). The prevalence of vaccine-induced immunity in the population aged 16-20 years was 73.0% (95% CI: 70.0-76.0). Compared with previous surveys, there was a decrease in the prevalence of HBV infection. Based on the prevalence of chronic infection (<1%), Madrid is a region with low HBV endemicity. Preventive strategies against HBV should especially target the immigrant population. Copyright © 2013.

El análisis de la eficiencia de estas ampliaciones ofrece los siguientes resultados: i el menor coste de la inversión de metro ligero ha permitido reducir los problemas financieros de los gobiernos madrileños; y ii la demanda por los nuevos servicios de transporte aumenta durante los primeros años, aunque desciende posteriormente. Estas conclusiones sugieren la complejidad de las decisiones económicas y políticas de estas ampliaciones, adaptadas a la evolución policéntrica y dispersa de Madrid.

    Full Text Available In Spain environmental surveillance has mainly relied on measures of selected pollutants in air, water, food and soil. A study was conducted in Madrid to assess the feasibility of implementing a surveillance system of exposure among the general population to specific environmental pollutants, using bio-markers. The project was basically focused on the environment surrounding newborns. Hence, the study population was made up of 145 triplets of pregnant women at around 8 months' gestation, their partners, and newborns from two areas, representing the two main types of urban environments in the region, i.e., the City of Madrid and its outlying metropolitan belt. Multiple biologic substrates were collected from each participant in order to assess the most suitable samples for an environmental surveillance system. The selected contaminants represent the main agents to which a population like that of Madrid is exposed every day, including certain heavy metals, persistent organic pollutants and polycyclic aromatic hydrocarbons, as well as micronuclei in peripheral blood, a commonly used unspecific index of cytogenetic damage. In addition, passive air samplers were placed around subjects' place of residence. This paper reports in detail on the design and response rates, summarizes field work results, and discusses some lessons learned.En España, la vigilancia medioambiental se basa principalmente en medidas de ciertos contaminantes en muestras de aire, agua, alimentos y suelos.

    The epithelial-mesenchymal transition (EMT) describes the global process by which stationary epithelial cells undergo phenotypic changes, including the loss of cell-cell adhesion and apical-basal polarity, and acquire mesenchymal characteristics that confer migratory capacity. EMT and its converse, MET (mesenchymal-epithelial transition), are integral stages of many physiologic processes and, as such, are tightly coordinated by a host of molecular regulators. Converging lines of evidence have identified EMT as a component of cutaneous wound healing, during which otherwise stationary keratinocytes (the resident skin epithelial cells) migrate across the wound bed to restore the epidermal barrier. Moreover, EMT plays a role in the development of scarring and fibrosis, as the matrix-producing myofibroblasts arise from cells of the epithelial lineage in response to injury but are pathologically sustained instead of undergoing MET or apoptosis. In this review, we summarize the role of EMT in physiologic repair and pathologic fibrosis of tissues and organs. We conclude that further investigation into the contribution of EMT to the faulty repair of fibrotic wounds might identify components of EMT signaling as common therapeutic targets for impaired healing in many tissues.

Nonsystematic review of the Madrid newspaper Gaceta de Madrid y Diario curioso, erudito, económico y comercial (Madrid Gazette, curious, erudite, financial and commercial) between 1759 and 1790. Review of the medical literature of the 18th century preserved in the Fondo Antiguo of the Biblioteca Histórica of Universidad Complutense de Madrid (Historical Resource of the Historical Library of the Complutense University of Madrid). A Google search of «Charles Richard de Beauregard». Charles de Beauregard focused his professional work mainly on the treatment of the urethral sequela of blennorrhagia, phimosis and paraphimosis. He introduced to 18th century Spanish society (with purported originality and clear commercial interests) therapeutic methods based on lead acetate that had already been developed in France by Thomas Goulard. The urethral sequela of diseases such as blennorrhagic urethritis, stenotic phimosis and paraphimosis were highly prevalent in 18th century Madrid and required complex solutions for the practice of urology of that era. Charles de Beauregard introduced innovative but not original treatments that were invasive but not bloody and that provided him with fame and social prestige. He advertised his professional activity and marketed his therapeutic products through advertisements submitted to the daily press (Madrid Gazette, Gaceta de Madrid). Copyright © 2015 AEU.

    2016-12-01

    Idiopathic pulmonary fibrosis (IPF) is an aging-associated, progressive, and irreversible lung disease of unknown etiology, elusive pathogenesis, and very limited therapeutic options. The hallmarks of IPF are aberrant activation of alveolar epithelial cells and accumulation of fibroblasts and myofibroblasts along with excessive production of extracellular matrix. The linkage of aging with this disorder is uncertain, but a number of changes associated with aging, including telomere attrition, cell senescence, and mitochondrial dysfunction, have been revealed in IPF lungs. Also, aging seems to confer a profibrotic phenotype upon fibroblasts and to increase the severity of the fibrogenic response in non-IPF fibrotic lung disorders. Better knowledge of the pathophysiological mechanisms linking aging to IPF will advance understanding of its pathogenesis and may provide new therapeutic windows to treatment of this devastating disease.

    Abnormal biliary secretion leads to the thickening of bile and the formation of plugs within the bile ducts; the consequent obstruction and abnormal bile flow ultimately results in the development of cystic fibrosis-related liver disease. This condition peaks in adolescence with up to 20% of adolescents with cystic fibrosis developing chronic liver disease. Early changes in the liver may ultimately result in end-stage liver disease with people needing transplantation. One therapeutic option currently used is ursodeoxycholic acid. This is an update of a previous review. To analyse evidence that ursodeoxycholic acid improves indices of liver function, reduces the risk of developing chronic liver disease and improves outcomes in general in cystic fibrosis. We searched the Cochrane CF and Genetic Disorders Group Trials Register comprising references identified from comprehensive electronic database searches, handsearches of relevant journals and abstract books of conference proceedings. We also contacted drug companies and searched online trial registries.Date of the most recent search of the Group's trials register: 09 April 2017. Randomised controlled trials of the use of ursodeoxycholic acid for at least three months compared with placebo or no additional treatment in people with cystic fibrosis. Two authors independently assessed trial eligibility and quality. The authors used GRADE to assess the quality of the evidence. Twelve trials have been identified, of which four trials involving 137 participants were included; data were only available from three of the trials (118 participants) since one cross-over trial did not report appropriate data. The dose of ursodeoxycholic acid ranged from 10 to 20 mg/kg/day for up to 12 months. The complex design used in two trials meant that data could only be analysed for subsets of participants. There was no significant difference in weight change, mean difference -0.90 kg (95% confidence interval -1.94 to 0.14) based on 30

    Cystic fibrosis is a genetic disorder which can lead to multiorgan dysfunction. Malabsorption of fat and fat-soluble vitamins (A, D, E, K) may occur and can cause subclinical deficiencies of some of these vitamins. Vitamin K is known to play an important role in both blood coagulation and bone formation. Supplementation with vitamin K appears to be one way of addressing the deficiency, but there is very limited agreement on the appropriate dose and frequency of use of these supplements. This is an updated version of the review. To assess the effects of vitamin K supplementation in people with cystic fibrosis and to determine the optimal dose and route of administration of vitamin K for both routine and therapeutic use. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group's Trials Register comprising references identified from comprehensive electronic database searches and handsearches of relevant journals and abstract books of conference proceedings.Most recent search: 30 January 2017. Randomised and quasi-randomised controlled trials of all preparations of vitamin K used as a supplement compared to either no supplementation (or placebo) at any dose or route and for any duration, in children or adults diagnosed with cystic fibrosis (by sweat test or genetic testing). Two authors independently screened papers, extracted trial details and assessed their risk of bias. Two trials (total of 32 participants) each lasting one month were included in the review and were assessed as having a moderate risk of bias. One was a dose-ranging parallel group trial in children (aged 8 to 18 years); and the other (with an older cohort) had a cross-over design comparing supplements to no treatment, but no separate data were reported for the first intervention period. Neither of the trials addressed any of the primary outcomes (coagulation, bone formation and quality of life). Both trials reported the restoration of serum vitamin K and undercarboxylated osteocalcin

    Cystic fibrosis is the most common autosomal recessive disease in white populations, and causes respiratory dysfunction in the majority of individuals. Numerous types of respiratory muscle training to improve respiratory function and health-related quality of life in people with cystic fibrosis have been reported in the literature. Hence a systematic review of the literature is needed to establish the effectiveness of respiratory muscle training (either inspiratory or expiratory muscle training) on clinical outcomes in cystic fibrosis. This is an update of a previously published review. To determine the effectiveness of respiratory muscle training on clinical outcomes in people with cystic fibrosis. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials register comprising of references identified from comprehensive electronic database searches and handsearches of relevant journals and abstract books of conference proceedings.Date of most recent search: 17 April 2018.A hand search of the Journal of Cystic Fibrosis and Pediatric Pulmonology was performed, along with an electronic search of online trial databases up until 07 May 2018. Randomised controlled studies comparing respiratory muscle training with a control group in people with cystic fibrosis. Review authors independently selected articles for inclusion, evaluated the methodological quality of the studies, and extracted data. Additional information was sought from trial authors where necessary. The quality of the evidence was assessed using the GRADE system MAIN RESULTS: Authors identified 19 studies, of which nine studies with 202 participants met the review's inclusion criteria. There was wide variation in the methodological and written quality of the included studies. Four of the nine included studies were published as abstracts only and lacking concise details, thus limiting the information available. Seven studies were parallel studies and two of a cross-over design. Respiratory

    Patients with cystic fibrosis (CF) have a relevant morbidity and mortality caused by CF-related liver-disease. While transient elastography (TE) is an established elastography method in hepatology centers, Acoustic-Radiation-Force-Impulse (ARFI)-Imaging is a novel ultrasound-based elastography method which is integrated in a conventional ultrasound-system. The aim of the present study was to evaluate the prevalence of liver-fibrosis in patients with CF using TE, ARFI-imaging and fibrosis blood tests. 106 patients with CF were prospectively included in the present study and received ARFI-imaging of the left and right liver-lobe, ARFI of the pancreas TE of the liver and laboratory evaluation. The prevalence of liver-fibrosis according to recently published best practice guidelines for CFLD was 22.6%. Prevalence of significant liver-fibrosis assessed by TE, ARFI-right-liver-lobe, ARFI-left-liver-lobe, Fibrotest, Fibrotest-corrected-by-haptoglobin was 17%, 24%, 40%, 7%, and 16%, respectively. The best agreement was found for TE, ARFI-right-liver-lobe and Fibrotest-corrected-by-haptoglobin. Patients with pancreatic-insufficiency had significantly lower pancreas-ARFI-values as compared to patients without. ARFI-imaging and TE seem to be promising non-invasive methods for detection of liver-fibrosis in patients with CF. Copyright © 2013 European Cystic Fibrosis Society. Published by Elsevier B.V.

    Full Text Available Hepatic fibrosis is the common pathological outcome of chronic hepatic diseases. An accurate assessment of fibrosis degree provides an important reference for a definite diagnosis of diseases, treatment decision-making, treatment outcome monitoring, and prognostic evaluation. At present, many clinical studies have proven that regression of hepatic fibrosis and early-stage liver cirrhosis can be achieved by effective treatment, and a correct evaluation of fibrosis regression has become a hot topic in clinical research. Liver biopsy has long been regarded as the gold standard for the assessment of hepatic fibrosis, and thus it plays an important role in the evaluation of fibrosis regression. This article reviews the clinical application of current pathological staging systems in the evaluation of fibrosis regression from the perspectives of semi-quantitative scoring system, quantitative approach, and qualitative approach, in order to propose a better pathological evaluation system for the assessment of fibrosis regression.

    Hepatic fibrosis is a wound healing response to insults and as such affects the entire world population. In industrialized countries, the main causes of liver fibrosis include alcohol abuse, chronic hepatitis virus infection and non-alcoholic steatohepatitis. A central event in liver fibrosis is the activation of hepatic stellate cells, which is triggered by a plethora of signaling pathways. Liver fibrosis can progress into more severe stages, known as cirrhosis, when liver acini are substituted by nodules, and further to hepatocellular carcinoma. Considerable efforts are currently devoted to liver fibrosis research, not only with the goal of further elucidating the molecular mechanisms that drive this disease, but equally in view of establishing effective diagnostic and therapeutic strategies. The present paper provides a state-of-the-art overview of in vivo and in vitro models used in the field of experimental liver fibrosis research.

    In the winter of 1811–1812 a series of three great earthquakes occurred in the New Madrid seismic zone. In addition to the three principal shocks, at least 15 other earthquakes, Io ≥ VIII, occurred within a year of the first large earthquake on December 16, 1811. The three main shocks were felt over the entire eastern United States. They were strong enough to cause minor damage as far away as Indiana and Ohio on the north, the Carolinas on the east, and southern Mississippi on the south. They were strong enough to cause severe or structural damage in parts of Missouri, Illinois, Indiana, Kentucky, Tennessee, Mississippi, and Arkansas. The section of this poster titled "Seismic history of the New Madrid region" describes what happened in the epicentral region. Fortunately, few people lived in the severely shaken area in 1811; that is not the case today. What would happen if a series of earthquakes as large and numerous as the "New Madrid" earthquakes were to occur in the New Madrid seismic zone today?

    Heart disease is a deadly syndrome affecting millions worldwide. It reflects an unmet clinical need, and the disease mechanisms are poorly understood. Cardiac fibrosis is central to heart disease. The four-membered family of transmembrane proteoglycans, syndecan-1 to -4, is believed to regulate fibrosis. We review the current literature concerning syndecans in cardiac fibrosis. Syndecan expression is up-regulated in response to pro-inflammatory stimuli in various forms of heart disease with fibrosis. Mice lacking syndecan-1 and -4 show reduced activation of pro-fibrotic signaling and increased cardiac rupture upon infarction indicating an important role for these molecules. Whereas the short cytoplasmic tail of syndecans regulates signaling, their extracellular part, substituted with heparan sulfate glycosaminoglycan chains, binds a plethora of extracellular matrix (ECM) molecules involved in fibrosis, e.g., collagens, growth factors, cytokines, and immune cell adhesion proteins. Full-length syndecans induce pro-fibrotic signaling, increasing the expression of collagens, myofibroblast differentiation factors, ECM enzymes, growth factors, and immune cell adhesion molecules, thereby also increasing cardiac stiffness and preventing cardiac rupture. Upon pro-inflammatory stimuli, syndecan ectodomains are enzymatically released from heart cells (syndecan shedding). Shed ectodomains affect the expression of ECM molecules, promoting ECM degradation and cardiac rupture upon myocardial infarction. Blood levels of shed syndecan-1 and -4 ectodomains are associated with hospitalization, mortality, and heart remodeling in patients with heart failure. Improved understanding of syndecans and their modifying enzymes in cardiac fibrosis might contribute to the development of compounds with therapeutic potential, and enzymatically shed syndecan ectodomains might constitute a future prognostic tool for heart diseases with fibrosis.

    Radioactive contamination of the soil due to a nuclear accident is a risk for the population. A research project, within the program of Radiological Protection by Intervention in CIEMAT, has been developed to study the behaviour of radionuclides in soils. An evaluation of the radiological vulnerability considering the external irradiation and the food chain pathway for caesium and strontium has been determined using partial and global indices, which indicate the potential transfer of the radionuclides via the two mentioned pathways. A detailed study of the soils found in the Autonomous Region of Madrid was carried out with data from individual soil profiles and combining data obtained from maps with a Geographic Information System in order to obtain a spatial distribution of the results. The soil vulnerability for the external irradiation pathway of caesium and strontium is in general found to be higher in more developed soils located in the south and leading to the foothills of the Sierra of Madrid in the north. the vulnerability for the food chain pathway is found to be higher in the less developed soils in acid conditions situated in the Sierra of Madrid.

    Although a considerable number of people either witnessed directly or in the mass media the traumatic scenes of the terrorist attack that took place on March 11th, 2004 in Madrid, only a fraction of Madrid citizens developed posttraumatic symptoms. In this study, posttraumatic stress-related symptoms, degree of exposure, coping strategies related to the attack, and chronic attempts to avoid intrusive thoughts (i.e., thought suppression) were assessed in a general population Madrid sample (N=503) 2-3 weeks after the attacks. Our results showed that participants with higher scores in chronic thought suppression exhibited higher levels of PTSD symptoms. Higher scores in chronic thought suppression also correlated positively with the use of avoidant coping strategies after the attacks. We discuss the possible common roots of avoidance of intrusive thoughts and avoidant coping strategies and the implications of this relationship for the emergence of stress-related symptoms as well as for public health policies.

    Full Text Available Acheck list of the Cynipidae from Comunidad de Madrid (Spain is presented for the first time. The data base contains 2189 records of samplings carried out from 1982 to the present in 103 sites in Madrid and 19 in nearby adjacent provinces. The list of 127 cynipid species from Madrid represents 73% of total Cynipidae species from the Iberian Peninsula. A distribution map in Madrid for each cynipid species is presented, showing the sampling sites where it has been found together with the potential distribution area of the species within the territory. Several aspects on the richness and distribution of the Cynipidae from Madrid are commented: potentially present and absent Iberian species, individual and rare species, and areas of high species richness. The area of highest richness for the Cynipidae of Madrid follows a strip of Cretacic and Tertiary soils along the Guadalix-Venturada-Torrelaguna axis, which also shows a high diversity of cynipid host plants, especially Quercus species. Other areas in SE Madrid deserving protection with regard to cynipids are also shown. These areas, some rich in rare and singular Aylacini species, other relictic areas with Quercus petraea in the Northeast and also some small areas with the presence of Quercus suber in parts of the territory of Madrid, deserve maximum protection concerning Cynipid conservation.

    Cystic Fibrosis (CF) is a genetic disease with equal prevalence across sexes. However, women present worse lung function with faster function decline, earlier onset of bacterial colonization, more frequent pulmonary exacerbations (PE), greater bronchial hyper-responsiveness, and higher mortality rates after puberty than men. The etiology of this gender disparity remains elusive but female hormones have been implicated in several studies. A 20-year-old female with CF with severe recurrent PE, always related to the menstrual cycle since menarche, combined with lung function decline requiring multiple courses of intravenous antibiotics. We report the cessation of PE and recovery of pulmonary function following the insertion of a subcutaneous implant with 68 mg of etonogestrel (Implanon®, Organon Española S.A. Laboratories, Madrid, Spain). Our case report supports the key role of female hormones in the development of PE and in the decline of lung function in a woman with CF. When appropriate, hormonal manipulation through contraceptive methods should be considered as potential treatment.

    Models made of wax had enormous diffusion in the anatomical teaching of the 18th century. It transcended the borders of a science that impregnated with scientific knowledge the artistic expression of beauty. Based on this premise, the San Carlos Royal College of Surgery created in Madrid a large collection of anatomical models, which is currently maintained by the Javier Puerta Anatomy Museum in the School of Medicine at Madrid Complutense University. The collection began in 1786 with Ignacio Lacaba, the first dissector of the Surgery College of Madrid, whose artistic sensibility and deep knowledge of anatomy contributed and facilitated harmonization between the work of the wax sculptors and language and anatomical expression.

    Nephrogenic systemic fibrosis is a new, rare disease of unknown cause that affects patients with renal failure. Single cases led to the suspicion of a causative role of gadodiamide that is used for magnetic resonance imaging. This study therefore reviewed all of the authors' confirmed cases...... of nephrogenic systemic fibrosis (n = 13) with respect to clinical characteristics, gadodiamide exposure, and subsequent clinical course. It was found that all had been exposed to gadodiamide before the development of nephrogenic systemic fibrosis. The delay from exposure to first sign of the disease was 2 to 75...... d (median 25 d). Odds ratio for acquiring the disease when gadodiamide exposed was 32.5 (95% confidence interval 1.9 to 549.2; P

    Pulmonary fibrosis is perhaps the most universal late effect of organ damage after both chemical insult and irradiation in the treatment of lung cancer. The use chemotherapy and radiation therapy, alone or combined, can be associated with clinically significant pulmonary toxicity, which leads to pneumonia and pulmonary fibrosis. It is also reported that about 100,000 people in the United States are suffered from pulmonary fibrosis. Therefore, pulmonary fibrosis will be more focused by medicinal researchers. Because current therapies, aimed at inhibiting pulmonary inflammation that often precedes fibrosis, are effective only in a minority of suffered patients, novel therapeutic methods are highly needed. Some researchers have used bleomycininduced pulmonary fibrosis as a basis for looking at the molecular mechanisms of fibrosis, and total gene expression was monitored using genomics method. However, radiation-induced pulmonary fibrosis has not been fully focused and investigated. Here, we have analyzed changes in gene expression in response to γ- irradiation by using proteomic analysis

  5. Proteinase activated receptor 1 mediated fibrosis in a mouse model of liver injury: a role for bone marrow derived macrophages.

    Directory of Open Access Journals (Sweden)

    Yiannis N Kallis

    Full Text Available Liver fibrosis results from the co-ordinated actions of myofibroblasts and macrophages, a proportion of which are of bone marrow origin. The functional effect of such bone marrow-derived cells on liver fibrosis is unclear. We examine whether changing bone marrow genotype can down-regulate the liver's fibrotic response to injury and investigate mechanisms involved. Proteinase activated receptor 1 (PAR1 is up-regulated in fibrotic liver disease in humans, and deficiency of PAR1 is associated with reduced liver fibrosis in rodent models. In this study, recipient mice received bone marrow transplantation from PAR1-deficient or wild-type donors prior to carbon tetrachloride-induced liver fibrosis. Bone marrow transplantation alone from PAR1-deficient mice was able to confer significant reductions in hepatic collagen content and activated myofibroblast expansion on wild-type recipients. This effect was associated with a decrease in hepatic scar-associated macrophages and a reduction in macrophage recruitment from the bone marrow. In vitro, PAR1 signalling on bone marrow-derived macrophages directly induced their chemotaxis but did not stimulate proliferation. These data suggest that the bone marrow can modulate the fibrotic response of the liver to recurrent injury. PAR1 signalling can contribute to this response by mechanisms that include the regulation of macrophage recruitment.

    Congenital hepatic fibrosis (CHF) is a disease of the biliary epithelium characterized by bile duct changes resembling ductal plate malformations and by progressive peribiliary fibrosis, in the absence of overt necroinflammation. Progressive liver fibrosis leads to portal hypertension and liver failure; however, the mechanisms leading to fibrosis in CHF remain elusive. CHF is caused by mutations in PKHD1, a gene encoding for fibrocystin, a ciliary protein expressed in cholangiocytes. Using a fibrocystin-defective (Pkhd1(del4/del4)) mouse, which is orthologous of CHF, we show that Pkhd1(del4/del4) cholangiocytes are characterized by a β-catenin-dependent secretion of a range of chemokines, including chemokine (C-X-C motif) ligands 1, 10, and 12, which stimulate bone marrow-derived macrophage recruitment. We also show that Pkhd1(del4/del4) cholangiocytes, in turn, respond to proinflammatory cytokines released by macrophages by up-regulating αvβ6 integrin, an activator of latent local transforming growth factor-β1. While the macrophage infiltrate is initially dominated by the M1 phenotype, the profibrogenic M2 phenotype increases with disease progression, along with the number of portal myofibroblasts. Consistent with these findings, clodronate-induced macrophage depletion results in a significant reduction of portal fibrosis and portal hypertension as well as of liver cysts. Fibrosis can be initiated by an epithelial cell dysfunction, leading to low-grade inflammation, macrophage recruitment, and collagen deposition; these findings establish a new paradigm for biliary fibrosis and represent a model to understand the relationship between cell dysfunction, parainflammation, liver fibrosis, and macrophage polarization over time. © 2015 by the American Association for the Study of Liver Diseases.

    Full Text Available Road traffic noise is one of the main concerns of large cities. Most of them have classified their territory in acoustic areas and have constructed strategic noise maps. From both sources we have elaborated seven types of acoustic neighbourhoods according to both their noise gap in regard to the legal standard and the percentage of population exposed to noise. A spatial Durbin model has been selected as the strategy that best models the impact of noise on housing prices. However, results for Madrid do not confirm the hedonic theory and indicate, as one of the possibilities, that the official acoustic areas in Madrid could be incorrectly designed.

    2004-12-01

    This special issue of Plasma Physics and Controlled Fusion comprises refereed papers contributed by invited speakers at the 31st European Physical Society Conference on Plasma Physics. The conference was jointly hosted by the Rutherford Appleton Laboratory, by the EURATOM/UKAEA Fusion Association and by Imperial College London, where it took place from 28 June to 2 July 2004. The overall agenda for this conference was set by the Board of the Plasma Physics Division of the European Physical Society, chaired by Friedrich Wagner (MPIPP, Garching) and his successor Jo Lister (CRPP, Lausanne). It built on developments in recent years, by further increasing the scientific diversity of the conference programme, whilst maintaining its depth and quality. A correspondingly diverse Programme Committee was set up, whose members are listed below. The final task of the Programme Committee has been the preparation of this special issue. In carrying out this work, as in preparing the scientific programme of the conference, the Programme Committee formed specialist subcommittees representing the different fields of plasma science. The chairmen of these subcommittees, in particular, accepted a very heavy workload on behalf of their respective research communities. It is a great pleasure to take this opportunity to thank: Emilia R Solano (CIEMAT, Madrid), magnetic confinement fusion; Jürgen Meyer-ter-Vehn (MPQ, Garching), laser-plasma interaction and beam plasma physics; and Jean-Luc Dorier (CRPP, Lausanne), dusty plasmas. The relatively few papers in astrophysical and basic plasma physics were co-ordinated by a small subcommittee which I led. Together with Peter Norreys (RAL, Chilton), we five constitute the editorial team for this special issue. The extensive refereeing load, compressed into a short time interval, was borne by the Programme Committee members and by many other experts, to whom this special issue owes much. We are also grateful to the Local Organizing Committee

    Full Text Available RESUMEN: Dentro de la enorme violencia presente en la Guerra Civil Española, el inicio de la misma en Madrid se caracterizó por la proliferación de episodios de violencia política, porque esas eran las razones que se argüían, e inorgánica, porque no se conectaba con proyecto revolucionario alguno. En este artículo se analiza una represión incontrolada que tenía como organismos claves las checas, de donde partían las policías de partido que efectuaban detenciones arbitrarias, y como episodios característicos los paseos: ejecuciones sin formación de causa y de forma clandestina. En las checas actuaban sujetos indeseables que generaron un clima de terror e inseguridad en Madrid en los enemigos de la República y en los sospechosos de pocas simpatías hacia el Frente Popular. Este clima de exceso y violencia fue objeto de preocupación de las autoridades republicanas en Madrid, siendo Santiago Carrillo, Consejero de Orden Público de la Junta de Defensa de Madrid, quien consiguió poner coto a los injustificables paseos. En la última parte del artículo se analiza este fenómeno de los paseos. Su ejecución fue sobre todo obra de anarquistas y, en mucha menor medida, de comunistas. Los hechos se iniciaban con la detención al anochecer y, la mayoría de las veces, terminaban con la ejecución de la víctima en la madrugada, casi en ocho de cada diez casos. Sus víctimas fueron sobre todo religiosos, seguidos de empleados y militares. El momento de mayor proliferación fue en los meses de agosto y septiembre de 1936, observándose un drástico descenso a partir de noviembre hasta su casi total desaparición a inicios de 1937, como un síntoma más del proceso de reconstrucción del Estado republicano. Palabras clave: Guerra Civil Española, Violencia política, Represión, Comunismo, Anarquismo.

    Essentials Epithelial cell apoptosis is critical in the pathogenesis of idiopathic pulmonary fibrosis. Protein S, a circulating anticoagulant, inhibited apoptosis of lung epithelial cells. Overexpression of protein S in lung cells reduced bleomycin-induced pulmonary fibrosis. Intranasal therapy with exogenous protein S ameliorated bleomycin-induced pulmonary fibrosis. Background Pulmonary fibrosis is the terminal stage of interstitial lung diseases, some of them being incurable and of unknown etiology. Apoptosis plays a critical role in lung fibrogenesis. Protein S is a plasma anticoagulant with potent antiapoptotic activity. The role of protein S in pulmonary fibrosis is unknown. Objectives To evaluate the clinical relevance of protein S and its protective role in pulmonary fibrosis. Methods and Results The circulating level of protein S was measured in patients with pulmonary fibrosis and controls by the use of enzyme immunoassays. Pulmonary fibrosis was induced with bleomycin in transgenic mice overexpressing human protein S and wild-type mice, and exogenous protein S or vehicle was administered to wild-type mice; fibrosis was then compared in both models. Patients with pulmonary fibrosis had reduced circulating levels of protein S as compared with controls. Inflammatory changes, the levels of profibrotic cytokines, fibrosis score, hydroxyproline content in the lungs and oxygen desaturation were significantly reduced in protein S-transgenic mice as compared with wild-type mice. Wild-type mice treated with exogenous protein S showed significant decreases in the levels of inflammatory and profibrotic markers and fibrosis in the lungs as compared with untreated control mice. After bleomycin infusion, mice overexpressing human protein S showed significantly low caspase-3 activity, enhanced expression of antiapoptotic molecules and enhanced Akt and Axl kinase phosphorylation as compared with wild-type counterparts. Protein S also inhibited apoptosis of alveolar

    Despite major research efforts leading to the recent approval of pirfenidone and nintedanib, the dismal prognosis of idiopathic pulmonary fibrosis (IPF) remains unchanged. The elaboration of international diagnostic criteria and disease stratification models based on clinical, physiological, radiological, and histopathological features has improved the accuracy of IPF diagnosis and prediction of mortality risk. Nevertheless, given the marked heterogeneity in clinical phenotype and the considerable overlap of IPF with other fibrotic interstitial lung diseases (ILDs), about 10% of cases of pulmonary fibrosis remain unclassifiable. Moreover, currently available tools fail to detect early IPF, predict the highly variable course of the disease, and assess response to antifibrotic drugs. Recent advances in understanding the multiple interrelated pathogenic pathways underlying IPF have identified various molecular phenotypes resulting from complex interactions among genetic, epigenetic, transcriptional, post-transcriptional, metabolic, and environmental factors. These different disease endotypes appear to confer variable susceptibility to the condition, differing risks of rapid progression, and, possibly, altered responses to therapy. The development and validation of diagnostic and prognostic biomarkers are necessary to enable a more precise and earlier diagnosis of IPF and to improve prediction of future disease behaviour. The availability of approved antifibrotic therapies together with potential new drugs currently under evaluation also highlights the need for biomarkers able to predict and assess treatment responsiveness, thereby allowing individualised treatment based on risk of progression and drug response. This approach of disease stratification and personalised medicine is already used in the routine management of many cancers and provides a potential road map for guiding clinical care in IPF.

    Because noise-induced hearing impairment is the result not only of occupational noise exposure but also of total daily noise exposure, it is important to take the non-occupational exposure of individuals (during commuting to and from their jobs, at home, and during recreational activities) into account. Mass transit is one of the main contributors to non-occupational noise exposure. We developed a new methodology to estimate a representative commuting noise exposure. The methodology was put into practice for the Madrid subway because of all Spanish subway systems it covers the highest percentage of worker journeys (22.6%). The results of the application highlight that, for Madrid subway passengers, noise exposure level normalized to a nominal 8 hr (L(Ex,8h-cj) ) depends strongly on the type of train, the presence of squealing noise, and the public address audio system, ranging from 68.6 dBA to 72.8 dBA. These values play an important role in a more complete evaluation of a relationship between noise dose and worker health response.

    When the chest is exposed to x radiation and Co-60 gamma radiation, radiation damage may occur in the lungs 2 to 10 weeks after irradiation. This condition is generally referred to as radiation pneumonitis, with the incidence ranging from 5.4% to 91.8% in the literature. Then radiation pneumonitis may develop into pulmonary fibrosis associated with roentgenologically diffuse linear and ring-like shadows and strong contraction 6 months to one year after irradiation. Until recently, little attention has been paid to pulmonary pneumonitis as a delayed effect of A-bomb radiation. The recent study using the population of 9,253 A-bomb survivors have suggested that the prevalence of pulmonary fibrosis tended to be high in heavily exposed A-bomb survivors. Two other studies using the cohort of 16,956 and 42,728 A-bomb survivors, respectively, have shown that the prevalence of roentgenologically proven pulmonary fibrosis was higher in men than women (1.82% vs 0.41%), was increased with aging and had a higher tendency in heavily exposed A-bomb survivors.

    Madrid has recently become the site of one of the most controversial cases of public healthcare reform in the European Union. Despite the fact that the introduction of New Public Management (NPM) into Madrid hospitals has been vigorous, little scholarship has been done to test whether NPM actually led to technical efficiency. This paper is one of the first attempts to do so. We deploy a bootstrapped data envelopment analysis to compare efficiency scores in traditionally managed hospitals and those operating with new management formulas. We do not find evidence that NPM hospitals are more efficient than traditionally managed ones. Moreover, our results suggest that what actually matters may be the management itself, rather than the management model. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available Durante los últimos años, la investigación sobre el Paleolítico en la región de Madrid ha proporcionado nuevos yacimientos y datos que permiten llevar a cabo una actualización de nuestro conocimiento del poblamiento humano de esta región durante el Pleistoceno superior. Las condiciones geo-litológicas de la cuenca sedimentaria madrileña, sumada a la peculiar fisiografía de sierra, pie de monte y cuenca drenada por una densa red fluvial, proporciona un contexto singular en el que el poblamiento parece organizarse funcionalmente atendiendo a los rasgos que cada contexto posee. Las comunidades musterienses supieron sacar provecho de una ordenada estructuración funcional del espacio. En este trabajo además de realizar una actualización del conocimiento en la región, planteamos como los grupos musterienses organizaron de manera planificada y complementaria la explotación de los distintos recursos en nuestra región respondiendo a patrones similares al de otras regiones europeas.In recent years, research on the Paleolithic in the region of Madrid has provided new archaeological sites, sequences and interpretations that allow us to update our knowledge about the human settlement in this region during the upper Pleistocene. Geo-lithological conditions of the Madrid sedimentary basin, combined with the peculiar physiography compose by mountains, slopes and basin drained by a dense river network provides a unique context in which the settlement seems to have been organized as a response to each particular context. During millennia, Mousterian communities learned to use a functional structure of space in order to organize the global activities. In this work, in addition to update our knowledge of the Mousterian occupation this region, we propose the existence of a organizational and complementary model of resource exploitation similar to other european regions.

    Full Text Available En este artículo se presentan y analizan los índices del costo de la vida de tres ciudades españolas, Palencia, Madrid y Sevilla, que cubren el periodo 1680-1800. Las contabilidades de diversos hospitales, colegios e instituciones benéficas han constituido la fuente principal para la elaboración de los referidos índices. En las tres urbes objeto de estudio los precios se comportaron de una manera bastante similar: todos los índices comparten tendencia y ciclo común y presentan un grado significativo de relación lineal entre sus tasas logarítmicas de variación. Sin embargo, también se observan diferencias significativas en los movimientos a corto y largo plazos de los precios: por un lado, las tensiones inflacionistas de la segunda mitad del siglo XVIII fueron más intensas en Palencia y en Sevilla que en la capital de la monarquía hispánica; por otro lado, en Madrid las fluctuaciones interanuales del costo de la vida fueron menos violentas que en Palencia y Sevilla. A nuestro juicio, hay evidencias que apuntan a que la singularidad de Madrid obedeció, ante todo, a la mayor cantidad de recursos que las instituciones públicas dedicaron en dicha urbe a la protección de los consumidores.In this article we present and analyze new cost of living indexes for three relevant Spanish urban centers that cover from 1680 to 1800. The accounts of several hospital, schools and charitable institutions have been used as main sources to construct these indexes. The three indexes behave in a fairly similar way. They share common trends and cycles and show a significant linear relationship among their logarithmic rates of variation. Nonetheless, some substantial differences in the short and the long term movement of prices may be observed as well. On the one hand, inflationary tensions in the second half of the eighteenth century were more intense in Palencia and Seville than in Madrid. On the other hand, yearly fluctuations in the cost of living

    2013-01-01

    Idiopathic pulmonary fibrosis (IPF) is characterized by the progressive and ultimately fatal accumulation of fibroblasts and extracellular matrix in the lung that distorts its architecture and compromises its function. IPF is now thought to result from wound-healing processes that, although initiated to protect the host from injurious environmental stimuli, lead to pathological fibrosis due to these processes becoming aberrant or over-exuberant. Although the environmental stimuli that trigger IPF remain to be identified, recent evidence suggests that they initially injure the alveolar epithelium. Repetitive cycles of epithelial injury and resultant alveolar epithelial cell death provoke the migration, proliferation, activation and myofibroblast differentiation of fibroblasts, causing the accumulation of these cells and the extracellular matrix that they synthesize. In turn, these activated fibroblasts induce further alveolar epithelial cell injury and death, thereby creating a vicious cycle of pro-fibrotic epithelial cell-fibroblast interactions. Though other cell types certainly make important contributions, we focus here on the “pas de deux” (steps of two), or perhaps more appropriate to IPF pathogenesis, the “folie à deux” (madness of two) of epithelial cells and fibroblasts that drives the progression of pulmonary fibrosis. We describe the signaling molecules that mediate the interactions of these cell types in their “fibrosis of two”, including transforming growth factor-β, connective tissue growth factor, sonic hedgehog, prostaglandin E2, angiotensin II and reactive oxygen species.

    Cystic fibrosis is the most common incurable hereditary disease in the US. Persistent respiratory infection is the leading cause of morbidity and mortality in cystic fibrosis patients. This study aimed to review the literature on economic and quality of life outcomes and treatment compliance associated with antibiotic therapies for cystic fibrosis patients. A systematic literature review was conducted using keyword searches of the MEDLINE database and selected conference abstracts. The review covered studies published between January 1990 and May 2007. Evidence suggests that inhaled tobramycin, a key chronic suppressive therapy, can reduce other healthcare costs. The main determinants of the cost of care include disease severity and respiratory infection. Costs vary widely by country. There is evidence that inhaled tobramycin and oral azithromycin improve quality of life and that treatment setting and patient convenience may also impact on quality of life. Antibiotic treatment compliance varied significantly and depended on the method of measurement, with more subjective measures tending to be higher. This review concludes by offering directions for future research.

    Fibrosis blood tests are usually developed using significant fibrosis, which is a unique diagnostic target; however, these tests are employed for other diagnostic targets, such as cirrhosis. We aimed to improve fibrosis staging accuracy by simultaneously targeting biomarkers for several diagnostic targets. A total of 3,809 patients were included, comprising 1,012 individuals with chronic hepatitis C (CHC) into a derivation population and 2,797 individuals into validation populations of different etiologies (CHC, chronic hepatitis B, human immunodeficiency virus/CHC, nonalcoholic fatty liver disease, alcohol) using Metavir fibrosis stages as reference. FibroMeter biomarkers were targeted for different fibrosis-stage combinations into classical scores by logistic regression. Independent scores were combined into a single score reflecting Metavir stages by linear regression and called Multi-FibroMeter Version Second Generation (V2G). The primary objective was to combine the advantages of a test targeted for significant fibrosis (FibroMeter V2G ) with those of a test targeted for cirrhosis (CirrhoMeter V2G ). In the derivation CHC population, we first compared Multi-FibroMeter V2G to FibroMeter V2G and observed significant increases in the cirrhosis area under the receiver operating characteristic curve (AUROC), Obuchowski index (reflecting all fibrosis-stage AUROCs), and classification metric (six classes expressed as a correctly classified percentage) and a nonsignificant increase in significant fibrosis AUROC. Thereafter, we compared it to CirroMeter V2G and observed a nonsignificant increase in the cirrhosis AUROC. In all 3,809 patients, respective accuracies for Multi-FibroMeter V2G and FibroMeter V2G were the following: cirrhosis AUROC, 0.906 versus 0.878 ( P fibrosis AUROC, 0.833 versus 0.832 ( P = 0.366). Multi-FibroMeter V2G had the highest correlation with the area of portoseptal fibrosis and the highest reproducibility over time. Correct classification rates

    Cystic fibrosis is a common autosomal recessive disorder with drastic respiratory symptoms, including shortness of breath and chronic cough. While most of cystic fibrosis treatment is dedicated to mitigating the effects of respiratory dysfunction, the potential effects of this disease on vocal parameters have not been systematically studied. We hypothesized that cystic fibrosis patients, given their characteristic respiratory disorders, would also present dysphonic symptoms. Given that voice disorders can severely impair quality of life, the identification of a potential cystic fibrosis-related dysphonia could be of great value for the clinical evaluation and treatment of this disease. We tested our hypothesis by measuring vocal parameters, using both objective physical measures and the GRBAS subjective evaluation method, in male and female cystic fibrosis patients undergoing conventional treatment and compared them to age and sex matched controls. We found that cystic fibrosis patients had a significantly lower vocal intensity and harmonic to noise ratio, as well as increased levels of jitter and shimmer. In addition, cystic fibrosis patients also showed higher scores of roughness, breathiness and asthenia, as well as a significantly altered general grade of dysphonia. When we segregated the results according to sex, we observed that, as a group, only female cystic fibrosis patients had significantly lower values of harmonic to noise ratio and an abnormal general grade of dysphonia in relation to matched controls, suggesting that cystic fibrosis exerts a more pronounced effect on vocal parameters of women in relation to men. Overall, the dysphonic characteristics of CF patients can be explained by dysfunctions in vocal fold movement and partial upper airway obstruction, potentially caused by the accumulation of mucus and chronic cough characteristic of CF symptomatology. Our results show that CF patients exhibit significant dysphonia and suggest they may

    The road transport system is closely linked to the land-use system. The road system connects territories at all spatial scale, on the other hand, passengers and freight travel behavior are strongly influenced both by land-use and the road transport system. Hence, research in the field of the interactions between land-use and the road transport system is still less, particular the influence of the economic crisis. This paper aims to find out if the statistical analysis of land use and mobility can help to answer the question of what happens during economic crisis on both land use and transport system, and unveiling key spatial relationships between them. The methodology for the analysis was developed accordingly with the data and resources available. First, an exploratory data analysis (EDA) is performed in order to identify the land use and mobility pattern during the last decade. This analysis focuses on six aspects, which are distribution of population and dwellings, employment and jobs, GDP, motorization and modal split. The second aspect consists on crossing the spatial patterns of the different aspects in order to find some explanatory relationships that indicate the presence of the key characteristics. The analysis is based on the case of Madrid Region. The land-use and transport data presented in this analysis are from 2004 to 2014, which are collected from the national statistical institute, the regional government database and two urban mobility surveys of Madrid. Through the exploration analysis, we find that there is close relationship between the land-use system and travel behavior in Madrid Region. With an increasing of new dwellings constructed in the outer periphery of Madrid Region, it leads longer trips distance and more travel cost particularly by car mode. Moreover, during the economic crisis, we also find the motorization level of Madrid keeps the same, as a result of the decreasing GDP and relatively decreasing. (Author)

    Full Text Available This article is a preliminary study of the fossil ruminants found in the Early Miocene site of La Encinilla (Colmenar Viejo, Madrid. The morphological description of dentition and postcranial bones, along with the metrical and comparative study with material from localities of similar age in France and Spain has allowed us to confirm the presence of two Pecoran ruminants in La Encinilla: Andegameryx sp. and a larger species related to Teruelia Moyá-Solá, 1987. Although the identification in one of the cases should be confirmed with more material, the record in the Madrid Bassin would represent new information regarding the known biogeographical distribution of both taxa. The systematic position of Andegameryx and Teruelia is still under discussion, but both forms are clearly distinct from the Cervoidea ruminants found in Europe and the Iberian Peninsula at the same age, such as Amphitragulus, Oriomeryx, Bedenomeryx or Dremotherium.Este trabajo constituye un estudio preliminar de los restos de rumiantes fósiles hallados en el yacimiento del Mioceno inferior de La Encinilla (Colmenar Viejo, Madrid.

    Despite the possible role of adiponectin in the pathogenesis of liver cirrhosis, few data have been collected from patients in different stages of liver fibrosis. We studied the role of adiponectin in 2 chronic hepatitis B (CHB)-patient cohorts. Serum adiponectin was quantified by enzyme-linked immunosorbent assay. One-hundred liver biopsy specimens from CHB patients with different stages of fibrosis and 38 paired liver biopsies from hepatitis B e antigen-positive patients randomized to lamivudine (n=15), pegylated interferon alfa-2a (n=15) or pegylated interferon alfa-2a plus lamivudine (n=8) therapy for 48 weeks were assessed. Serum adiponectin was detected at levels ranging over fourfold magnitude with advancing fibrosis stage and correlated positively with fibrosis stage [r=0.45, p<0.001]. CHB patients with stage 0-1 fibrosis had higher composition of high molecular weight (HMW) form of adiponectin when compared with CHB patients with liver cirrhosis [mean+/-SEM 51.2+/-2.1% vs. 40.9+/-1.7%, respectively, p=0.001]. After antiviral therapy, patients with fibrosis reduction had marked decline in serum adiponectin level and increase in HMW form of adiponectin [mean+/-SEM 43.5+/-1.2% vs. 37.0+/-3.0%, respectively, p=0.04]. Serum adiponectin may have a role in fibrosis progression in CHB infection. A marked decline in serum adiponectin after antiviral therapy is associated with fibrosis reduction.

This article examines the insertion in the labor market of the Senegalese immigrants in Madrid and depicts their main sociodemographic characteristics according to gender. The description of these foreign workers according to gender, age, civil status and level of education allows us to treat them as a human capital, in search of real opportunities in Madrid's labor market. As a result, the analysis presents a basic overview of their economic activities in Madrid while focusing on men who have set up retail business: they are hawkers. Thus, it is noteworthy to point out the social ties (intra/inter-ethnic and transnational networks that support some of them as a group, while getting a job and evolving their commercial activities. However, others are marginalized and isolated in these segments of the labor market where they develop strategies in order to avoid or escape Police assault and prosecution because they are illegal migrants; meanwhile, another group of people

    Radioactive contamination of the soil due to a nuclear accident is a risk for the population. A research project, within the program of Radiological Protection by Intervention in CIEMAT, has been developed to study the behaviour of radionuclides in soils. An evaluation of the radiological vulnerability considering the external irradiation and the food chain pathway for caesium and strontium has been determined using partial and global indices, which indicate the potential transfer of the radionuclides via the two mentioned pathways. A detailed study of the soils found in the Autonomous Region of Madrid was carried out with data from individual soil profiles and combining data obtained from maps with a Geographic Information System in order to obtain a spatial distribution of the results. The soil vulnerability for the external irradiation pathway of caesium and strontium is in general found to be higher in more developed soils located in the south and leading to the foothills of the Sierra of Madrid in the north. The vulnerability for the food chain pathway is found to be higher in the less developed soils in acid conditions situated in the Sierra of Madrid. (Author) 11 refs

    Full Text Available The Madrid Royal Schools of Saint Elizabeth and Loreto were founded by Philip II at the end of 16th Century. Both institutions provided education for orphan girls. They still exist as Catholic coeducational schools granted by the Education Department. These two Schools were Royal Sponsorship belonging to Palace ecclesiastical jurisdiction. The Schools Constitutions sanctioned by Philip V have been preserved until now. Although these Schools have a parallel history, the mentioned Constitutions are completely different for each School. According to these Norms, the Madrid Royal Schools of Saint Elizabeth and Loreto have many differences between them.Los Reales Colegios de Santa Isabel y Loreto de Madrid para niñas huérfanas fueron fundados por Felipe II a finales del siglo XVI. Ambas instituciones siguen funcionando en la actualidad como centros educativos católicos mixtos y concertados. Los dos fueron patronatos reales pertenecientes a la jurisdicción eclesiástica de Palacio. Se han conservado las Constituciones de ambos aprobadas bajo el reinado de Felipe V. Aunque los Colegios tienen una historia paralela, la citada normativa es muy diferente para cada institución; según las Constituciones, Santa Isabel y Loreto tienen más aspectos diferenciadores que comunes.

    In most Western countries young people adopt lifestyles that adversely affect their health, thus increasing the risk of premature onset of chronic diseases. Therefore, the aim of this study was to compare patterns of habits in pre-university and university students in west-central area of Madrid. Descriptive longitudinal study with randomly selected students from Madrid in Madrid universities and schools-institutes. Accepting to participate 1590 students of both sex: 653 males (4,1%) and 937 women (58,9%). To facilitate the study were classified into ≤ 17 years (pre university) and ≥ 18 years (university). BMI, physical activity, alcohol consumption and negative habits with regard to food consumption was studied. Almost 80% have normal weight, are more active pre-university. Gender differences were observed, which should guide the actions of intervention in terms of physical activity or habits. It seems essential to make nutritional programs as well as psychosocial intervention in adolescents and youth to prevent and / or reduce alcohol consumption. Copyright AULA MEDICA EDICIONES 2014.

    Full Text Available This study aimed to analyze the state of the art of adapted physical activity for persons with disabilities in the region of Madrid. To meet this goal, official demographic data and indicators of participation in physical activity programs from 2014 were analyzed. Results indicated a population of 307.880 persons with disability (4.7 % of the entire population. The largest population group among the persons with disabilities is composed by persons with a physical disability. Less than 2.53 % of the population with disability practiced a competitive sport and 21.49 % of persons with disabilities living in Madrid were holders of the “Special Card” that provided them with free access to all public sport facilities. However, no indicator was found related with the participation of the population with disabilities on leisure or health physical activities in the region of Madrid. These results suggest that there is a need for improving monitoring through official indicators and to establish further actions that responds to the analyzed demographic profile.

    Full Text Available The patient was a 4-month-old infant, who underwent persistent ductus arteriosus interruption with titanium clips at the age of 13 days and, since the age of 2 months, had crises of hypoxia and hypertonicity. After clinical investigation, the presence of pulmonary hypertension was confirmed and left ventricular inflow tract obstruction was suspected. The patient underwent surgical treatment at the age of 4 months, during which right and left ventricular endocardial fibrosis was identified. The fibrosis was resected, but the infant had an unfavorable clinical evolution with significant diastolic restriction and died on the sixth postoperative day. Anatomicopathological and surgical findings suggested endomyocardial fibrosis, although that pathology is very rare at the patient's age.

    Cystic fibrosis has historically been considered a pulmonary disease, but with the increasing life expectancy of these patients, gastrointestinal manifestations are becoming more important. Furthermore, nutritional status is closely linked to pulmonary function and, thus, overall mortality. This article discusses gastrointestinal manifestations (which involve nutritional, pancreatic, hepatobiliary, and, in particular, gastrointestinal tract issues) of cystic fibrosis as well as management of the disease. In addition, the article discusses studies that have been critical to our understanding of gastrointestinal manifestations of cystic fibrosis. PMID:27330503

  14. Therapeutic targets in liver fibrosis.

    Fallowfield, Jonathan A

    2011-05-01

    Detailed analysis of the cellular and molecular mechanisms that mediate liver fibrosis has provided a framework for therapeutic approaches to prevent, slow down, or even reverse fibrosis and cirrhosis. A pivotal event in the development of liver fibrosis is the activation of quiescent hepatic stellate cells (HSCs) to scar-forming myofibroblast-like cells. Consequently, HSCs and the factors that regulate HSC activation, proliferation, and function represent important antifibrotic targets. Drugs currently licensed in the US and Europe for other indications target HSC-related components of the fibrotic cascade. Their deployment in the near future looks likely. Ultimately, treatment strategies for liver fibrosis may vary on an individual basis according to etiology, risk of fibrosis progression, and the prevailing pathogenic milieu, meaning that a multiagent approach could be required. The field continues to develop rapidly and starts to identify exciting potential targets in proof-of-concept preclinical studies. Despite this, no antifibrotics are currently licensed for use in humans. With epidemiological predictions for the future prevalence of viral, obesity-related, and alcohol-related cirrhosis painting an increasingly gloomy picture, and a shortfall in donors for liver transplantation, the clinical urgency for new therapies is high. There is growing interest from stakeholders keen to exploit the market potential for antifibrotics. However, the design of future trials for agents in the developmental pipeline will depend on strategies that enable equal patient stratification, techniques to reliably monitor changes in fibrosis over time, and the definition of clinically meaningful end points.

    The February 7, 1812, New Madrid, Missouri, earthquake (M [moment magnitude] 8) was the third and final large-magnitude event to rock the northern Mississippi Embayment during the winter of 1811-1812. Although ground shaking was so strong that it rang church bells, stopped clocks, buckled pavement, and rocked buildings up and down the eastern seaboard, little coseismic surface deformation exists today in the New Madrid area. The fault(s) that ruptured during this event have remained enigmatic. We have integrated geomorphic data documenting differential surficial deformation (supplemented by historical accounts of surficial deformation and earthquake-induced Mississippi River waterfalls and rapids) with the interpretation of existing and recently acquired seismic reflection data, to develop a tectonic model of the near-surface structures in the New Madrid, Missouri, area. This model consists of two primary components: a northnorthwest-trending thrust fault and a series of northeast-trending, strike-slip, tear faults. We conclude that the Reelfoot fault is a thrust fault that is at least 30 km long. We also infer that tear faults in the near surface partitioned the hanging wall into subparallel blocks that have undergone differential displacement during episodes of faulting. The northeast-trending tear faults bound an area documented to have been uplifted at least 0.5 m during the February 7, 1812, earthquake. These faults also appear to bound changes in the surface density of epicenters that are within the modern seismicity, which is occurring in the stepover zone of the left-stepping right-lateral strike-slip fault system of the modern New Madrid seismic zone.

They can result from various causes, both infectious and noninfectious diseases. The application of nanoparticle (NP systems has emerged as a rapidly evolving area of interest for the safe delivery of various drugs and nucleic acids for chronic liver diseases. This review presents the pathogenesis, diagnosis and the emerging nanoparticulate systems used in the treatment of chronic liver diseases caused by liver fibrosis. Activated hepatic stellate cell (HSC is considered to be the main mechanism for liver fibrosis. Ultrasonography and magnetic resonance imaging techniques are widely used noninvasive diagnostic methods for hepatic fibrosis. A variety of nanoparticulate systems are mainly focused on targeting HSC in the treatment of hepatic fibrosis. As early liver fibrosis is reversible by current NP therapy, it is being studied in preclinical as well as clinical trials. Among various nanoparticulate systems, inorganic NPs, liposomes and nanomicelles have been widely studied due to their distinct properties to deliver drugs as well as other therapeutic moieties. Liposomal NPs in clinical trials is considered to be a milestone in the treatment of hepatic fibrosis. Currently, NP therapy for liver fibrosis is updating fast, and hopefully, it can be the future remedy for liver fibrosis. Keywords: liver fibrosis, inorganic nanoparticles, liposomes, micelles

    Full Text Available Transient elastography (TE, a non-invasive tool that measures liver stiffness, has been evaluated in meta-analyses for effectiveness in assessing liver fibrosis in European populations with chronic hepatitis C (CHC. However, these data cannot be extrapolated to populations in Asian countries, where chronic hepatitis B (CHB is more prevalent. In this study, we performed a meta-analysis to assess the overall performance of TE for assessing liver fibrosis in patients with CHB.Studies from the literature and international conference abstracts which enrolled only patients with CHB or performed a subgroup analysis of such patients were enrolled. Combined effects were calculated using area under the receiver operating characteristic curves (AUROC and diagnostic accuracy values of each study.A total of 18 studies comprising 2,772 patients were analyzed. The mean AUROCs for the diagnosis of significant fibrosis (F2, severe fibrosis (F3, and cirrhosis (F4 were 0.859 (95% confidence interval [CI], 0.857-0.860, 0.887 (95% CI, 0.886-0.887, and 0.929 (95% CI, 0.928-0.929, respectively. The estimated cutoff for F2 was 7.9 (range, 6.1-11.8 kPa, with a sensitivity of 74.3% and specificity of 78.3%. For F3, the cutoff value was determined to be 8.8 (range, 8.1-9.7 kPa, with a sensitivity of 74.0% and specificity of 63.8%. The cutoff value for F4 was 11.7 (range, 7.3-17.5 kPa, with a sensitivity of 84.6% and specificity of 81.5%.TE can be performed with good diagnostic accuracy for quantifying liver fibrosis in patients with CHB.

    Full Text Available Abstract Background Liver fibrosis is a stage of non-alcoholic fatty liver disease (NAFLD which is responsible for liver-related morbidity and mortality in adults. Accordingly, the search for non-invasive markers of liver fibrosis has been the subject of intensive efforts in adults with NAFLD. Here, we developed a simple algorithm for the prediction of liver fibrosis in children with NAFLD followed at a tertiary care center. Methods The study included 136 male and 67 female children with NAFLD aged 3.3 to 18.0 years; 141 (69% of them had fibrosis at liver biopsy. On the basis of biological plausibility, readily availability and evidence from adult studies, we evaluated the following potential predictors of liver fibrosis at bootstrapped stepwise logistic regression: gender, age, body mass index, waist circumference, alanine transaminase, aspartate transaminase, gamma-glutamyl-transferase, albumin, prothrombin time, glucose, insulin, triglycerides and cholesterol. A final model was developed using bootstrapped logistic regression with bias-correction. We used this model to develop the 'pediatric NAFLD fibrosis index' (PNFI, which varies between 0 and 10. Results The final model was based on age, waist circumference and triglycerides and had a area under the receiver operating characteristic curve of 0.85 (95% bootstrapped confidence interval (CI with bias correction 0.80 to 0.90 for the prediction of liver fibrosis. A PNFI ≥ 9 (positive likelihood ratio = 28.6, 95% CI 4.0 to 201.0; positive predictive value = 98.5, 95% CI 91.8 to 100.0 could be used to rule in liver fibrosis without performing liver biopsy. Conclusion PNFI may help clinicians to predict liver fibrosis in children with NAFLD, but external validation is needed before it can be employed for this purpose.

    2000-01-01

    Suspended particles are a very complex type of atmospheric pollution because of their chemical composition and size. In fact, there are a quite high number of particles sources which are linked to different physicochemical processes that determine their size. At present particles smaller than 10 μm are considered the most dangerous, as has been recently pointed out by numerous epidemiologic studies. In this way, more restrictive concentration limit values have been approved in the EU countries, so an assessment of present airborne concentration values and the sources apportionment in their most representative areas is needed. In the Madrid Community a first approaching of these and other aims, has been carried out from an analysis of the Madrid Air Quality networks data. This will contribute to the establishment of concentration levels abatement strategies. (Author) 111 refs

    Full Text Available Abstract Background Pathogens with the zoonotic potential to infect humans, such as Campylobacter jejuni, Campylobacter coli and Chlamydophila psittaci, can be found in feral pigeons (Columba livia. Given the high density of these birds in the public parks and gardens of most cities, they may pose a direct threat to public health. Methods A total of 118 pigeons were captured in three samplings carried out in 2006-2007 in public parks and gardens in Madrid, Spain. Standard haematological and morphological analyses were carried out on the pigeons. PCR was used to screen for the presence of Campylobacter jejuni, C. coli and Chlamydophila psittaci. Positive samples were confirmed by DNA sequencing. Results The analyses demonstrated a high prevalence of Chlamydophila psittaci (52.6% and Campylobacter jejuni (69.1% among the birds captured. In contrast, Campylobacter coli was rarely detected (1.1%. Conclusions Pigeons in Madrid can carry Chlamydophila psittaci and Campylobacter jejuni. They may be asymptomatic or subclinical carriers of both pathogens.

    This article tests a hypothesized model of overall happiness among homeless people in Spain. The research was conducted based on a representative sample of homeless people in Madrid (n = 235), all adults, who had spent the night before the interview in a shelter for homeless people, on the street or in other places not initially designed for sleeping, or who were in supervised accommodation for homeless people at the time of the interview. Information was gathered using a structured interview. The results obtained show that around half of the homeless people in Madrid said that they were happy. A positive meta-stereotype and a better perceived general health were associated with a higher overall happiness, while feelings of loneliness were associated with a lower overall happiness. Happiness also showed a significant effect on future expectations. Disabilities and handicaps had a significant effect on perceived general health, which was in turn associated with overall happiness among homeless people. (c) 2015 APA, all rights reserved).

  8. Liver Fibrosis: Current Principles of Diagnosis

    Directory of Open Access Journals (Sweden)

    A.K. Duda

    2014-09-01

    Full Text Available Liver fibrosis — a natural consequence of almost all liver diseases of any origin. We are faced with a number of standard stereotype processes that take place in the liver tissue. Mostly it is the processes of chronic inflammation, which oppose the processes of liver tissue regeneration. The basis of imbalance between the processes of fibrosis and regeneration is an accumulation of extracellular matrix. Liver fibrosis in its development leads to liver cirrhosis, hepatocellular carcinoma, and the increase in morbidity rate is observed worldwide. Furthermore, the process is genetically determined, but modifiable factors play an important role in the progression of this disease. Current data indicate the possibility of reversible liver fibrosis.

  9. A multi-methodological approach to study the temporal and spatial distribution of air quality related to road transport emissions in Madrid, Spain

    2013-04-01

    The traffic-related atmospheric emissions, composition and transport of greenhouse gases (GHGs) and air toxic pollutants (ATPs), are an important environmental problem that affect climate change and air pollution in Madrid, Spain. Carbon dioxide (CO2) affects the regional weather and particularly fine particle matter (PM) translocate to the people resulting in local health problems. As the main source of emissions comes from road transport, and subsequent combustion of fossil fuels, air quality deterioration may be elevated during weekdays and peak hours. We postulate that traffic-related air quality (CO2, methane CH4, PM, volatile organic compounds VOCs, nitrogen oxides NOx and carbon monoxide CO contents) impairs epidemiology in part via effects on health and disease development, likely increasing the external costs of transport in terms of climate change and air pollution. First, the paper intends to estimate the local air quality related to the road transport emissions of weeks over a domain covering Madrid (used as a case study). The local air quality model (LAQM) is based on gridded and shaped emission fields. The European Environmental Agency (EEA) COPERT modeling system will provide GHGs and ATPs gridded and shaped emission data and mobile source parameters, available for Madrid from preliminary emission inventory records of the Municipality of Madrid and from disaggregated traffic counts of the Traffic Engineering Company and the Metropolitan Company of Metro (METRO-Madrid). The paper intends to obtain estimates of GHGs and ATPs concentrations commensurate with available ground measurements, 24-hour average values, from the Municipality of Madrid. The comparison between estimated concentrations and measurements must show small errors (e.g. fractional error, fractional bias and coefficient of determination). The paper's expected results must determine spatial and temporal patterns in Madrid. The estimates will be used to cross check the primary local

    Cystic fibrosis is an autosomal recessive multisystem disorder with an approximate prevalence of 1 in 3500 live births. Allergic bronchopulmonary aspergillosis is a lung disease caused by aspergillus-induced hypersensitivity with a prevalence of 2% to 15% in people with cystic fibrosis. The mainstay of treatment includes corticosteroids and itraconazole. The treatment with corticosteroids for prolonged periods of time, or repeatedly for exacerbations of allergic bronchopulmonary aspergillosis, may lead to many adverse effects. The monoclonal anti-IgE antibody, omalizumab, has improved asthma control in severely allergic asthmatics. The drug is given as a subcutaneous injection every two to four weeks. Since allergic bronchopulmonary aspergillosis is also a condition resulting from hypersensitivity to specific allergens, as in asthma, it may be a candidate for therapy using anti-IgE antibodies. Therefore, anti-IgE therapy, using agents like omalizumab, may be a potential therapy for allergic bronchopulmonary aspergillosis in people with cystic fibrosis. This is an updated version of the review. To evaluate the efficacy and adverse effects of anti-IgE therapy for allergic bronchopulmonary aspergillosis in people with cystic fibrosis. We searched the Cochrane Cystic Fibrosis Trials Register, compiled from electronic database searches and handsearching of journals and conference abstract books.

    The third International Conference on Mathematical Modeling in Physical Sciences (IC-MSQUARE) took place at Madrid, Spain, from Thursday 28 to Sunday 31 August 2014. The Conference was attended by more than 200 participants and hosted about 350 oral, poster, and virtual presentations. More than 600 pre-registered authors were also counted. The third IC-MSQUARE consisted of different and diverging workshops and thus covered various research fields where Mathematical Modeling is used, such as Theoretical/Mathematical Physics, Neutrino Physics, Non-Integrable Systems, Dynamical Systems, Computational Nanoscience, Biological Physics, Computational Biomechanics, Complex Networks, Stochastic Modeling, Fractional Statistics, DNA Dynamics, Macroeconomics etc. The scientific program was rather heavy since after the Keynote and Invited Talks in the morning, three parallel oral sessions and one poster session were running every day. However, according to all attendees, the program was excellent with high level of talks and the scientific environment was fruitful, thus all attendees had a creative time. We would like to thank the Keynote Speaker and the Invited Speakers for their significant contribution to IC-MSQUARE. We also would like to thank the Members of the International Advisory and Scientific Committees as well as the Members of the Organizing Committee.

    Carvalho, Carolina Pimenta

    2008-12-01

    Full Text Available Introduction: Cystic Fibrosis is the most common recessive autosomic genetic disease among Caucasians. It's caused by mutations in the gene that decodes regulatory protein for transmembrane conductance, resulting in defective transport of chlorine. Objective: Review the literature about Cystic Fibrosis, with emphasis on otorhinolaryngologic manifestations. Method: The online Pub Med databases were researched and we applied the following search terms Fibrosis Cystic and Sinusitis, and Mucoviscidosis and Sinusitis. Conclusions: Although it is not the main cause of death, the otorhinolaryngologic manifestations of the Cystic Fibrosis bring important morbidity to these patients.

    2008-04-01

    Full Text Available Idiopathic Pulmonary Fibrosis (IPF is a refractory and lethal interstitial lung disease characterized by loss of alveolar epithelial cells, fibroblast proliferation and extra-cellular matrix protein deposition. EBV, localised to alveolar epithelial cells of pulmonary fibrosis patients is associated with a poor prognosis. In this study we utilised a microarray-based differential gene expression analysis strategy to identify molecular drivers of EBV associated with lung fibrosis. A549 cells and an alveolar epithelial cell line infected with EBV (VAAK were used to identify genes whose expression was altered by EBV reactivation. EBV reactivation by TGFbeta1 drives alterations in expression of non-canonical Wnt pathway mediators, implicating it in epithelial mesenchymal transition (EMT, the molecular event underpinning scar production in tissue fibrosis. Cell invasion, EMT correlated transcripts expression, GSK-3b and c-Jun activation were altered in response to non-canonical Wnt pathway regulation. The role of EBV in promoting fibrosis can be attenuated by antiviral strategies and inhibition of Wnt signalling. Activation of non-canonical Wnt signalling pathway by EBV in epithelial cells suggests a novel mechanism of tissue fibrosis. These data present a framework for further description of the link between infectious agents and fibrosis, a significant disease burden.

    2015-01-01

    Full Text Available Objective: The present mini-review updated the progress in methodologies based on using liver biopsy. Data Sources: Articles for study of liver fibrosis, liver biopsy or fibrosis assessment published on high impact peer review journals from 1980 to 2014. Study Selection: Key articles were selected mainly according to their levels of relevance to this topic and citations. Results: With the recently mounting progress in chronic liver disease therapeutics, comes by a pressing need for precise, accurate, and dynamic assessment of hepatic fibrosis and cirrhosis in individual patients. Histopathological information is recognized as the most valuable data for fibrosis assessment. Conventional histology categorical systems describe the changes of fibrosis patterns in liver tissue; but the simplified ordinal digits assigned by these systems cannot reflect the fibrosis dynamics with sufficient precision and reproducibility. Morphometric assessment by computer assist digital image analysis, such as collagen proportionate area (CPA, detects change of fibrosis amount in tissue section in a continuous variable, and has shown its independent diagnostic value for assessment of advanced or late-stage of fibrosis. Due to its evident sensitivity to sampling variances, morphometric measurement is feasible to be taken as a reliable statistical parameter for the study of a large cohort. Combining state-of-art imaging technology and fundamental principle in Tissue Engineering, structure-based quantitation was recently initiated with a novel proof-of-concept tool, qFibrosis. qFibrosis showed not only the superior performance to CPA in accurately and reproducibly differentiating adjacent stages of fibrosis, but also the possibility for facilitating analysis of fibrotic regression and cirrhosis sub-staging. Conclusions: With input from multidisciplinary innovation, liver biopsy assessment as a new "gold standard" is anticipated to substantially support the accelerated

    Full Text Available Hepatic fibrosis is the common outcome of chronic liver diseases of various causes. At present, liver biopsy is the “gold standard” for the diagnosis of liver fibrosis, but it has limitations and is invasive, which leads to the development of noninvasive assessment of liver fibrosis. The article mainly introduces the technology and application of noninvasive diagnosis of liver fibrosis from the aspects of clinical manifestation, serology, and radiology. It has pointed out the clinical value of these noninvasive diagnosis techniques, and it discusses the progress in clinical research and its limitations for noninvasive diagnosis of liver fibrosis.

    Two patients presented with ureteric obstruction, and voiding symptoms and constipation, respectively, and were examined by means of intravenous urography and computed tomography. One patient was additionally examined by means of MR tomography. After CT (performed in both patients) and MRT (performed in one patient) had shown a diffuse, contrast-enhancing, infiltrating process in the small pelvis with infiltration of adjacent organs and vessels, surgical biopsy proved the diagnosis of idopathic pelvic fibrosis. Extension of retroperitoneal fibrosis below the pelvic rim is very rare. Clinical symptoms of pelvic fibrosis are variable and imaging findings may lead to a broad list of differential diagnoses. We present two patients with idiopathic pelvic fibrosis and discuss radiological findings and differential diagnoses of this rare disease. (orig.)

    Adaptive multiple features method (AMFM) lung texture analysis software recognizes high-resolution computed tomography (HRCT) patterns. To evaluate AMFM and visual quantification of HRCT patterns and their relationship with disease progression in idiopathic pulmonary fibrosis. Patients with idiopathic pulmonary fibrosis in a clinical trial of prednisone, azathioprine, and N-acetylcysteine underwent HRCT at study start and finish. Proportion of lung occupied by ground glass, ground glass-reticular (GGR), honeycombing, emphysema, and normal lung densities were measured by AMFM and three radiologists, documenting baseline disease extent and postbaseline change. Disease progression includes composite mortality, hospitalization, and 10% FVC decline. Agreement between visual and AMFM measurements was moderate for GGR (Pearson's correlation r = 0.60, P fibrosis (as measured by GGR densities) is independently associated with elevated hazard for disease progression. Postbaseline change in AMFM-measured and visually measured GGR densities are modestly correlated with change in FVC. AMFM-measured fibrosis is an automated adjunct to existing prognostic markers and may allow for study enrichment with subjects at increased disease progression risk.

    In this work, we present an automatic method for liver segmentation and fibrosis classification in liver computed-tomography (CT) portal phase scans. The input is a full abdomen CT scan with an unknown number of slices, and the output is a liver volume segmentation mask and a fibrosis grade. A multi-stage analysis scheme is applied to each scan, including: volume segmentation, texture features extraction and SVM based classification. Data contains portal phase CT examinations from 80 patients, taken with different scanners. Each examination has a matching Fibroscan grade. The dataset was subdivided into two groups: first group contains healthy cases and mild fibrosis, second group contains moderate fibrosis, severe fibrosis and cirrhosis. Using our automated algorithm, we achieved an average dice index of 0.93 ± 0.05 for segmentation and a sensitivity of 0.92 and specificity of 0.81for classification. To the best of our knowledge, this is a first end to end automatic framework for liver fibrosis classification; an approach that, once validated, can have a great potential value in the clinic.

  4. Factors Promoting Development of Fibrosis in Crohn’s Disease

    Gerhard Rogler

    2017-07-01

    Full Text Available The concepts on the pathophysiology of intestinal fibrosis in Crohn’s disease (CD have changed in recent years. Some years ago fibrosis was regarded to be a consequence of long-standing inflammation with subsequent destruction of the gut wall matrix followed by scar formation and collagen deposition. Fibrosis in CD patients appeared to be an irreversible process that could hardly be influenced. Therefore, the main target in CD therapy was to control inflammation to avoid fibrosis development. Many of these assumptions seem to be only partially true. Inflammation may be a necessary prerequisite for the initiation of fibrosis. However, when the pathophysiologic processes that lead to fibrosis in CD patients have been initiated fibrosis development may be independent of inflammation and may continue even when inflammation is under good medical control. Fibrosis in CD also may be reversible. After strictureplasty local collagen deposits decrease or even disappear. With new animal models for intestinal fibrosis on the horizon, we need to spend more efforts on understanding the factors influencing fibrosis in CD patients to finally find specific therapies. In this context, it will be as important to find markers and quantitative imaging tools to have reliable endpoints for clinical trials in fibrosing CD.

    Autogenic drainage is an airway clearance technique that was developed by Jean Chevaillier in 1967. The technique is characterised by breathing control using expiratory airflow to mobilise secretions from smaller to larger airways. Secretions are cleared independently by adjusting the depth and speed of respiration in a sequence of controlled breathing techniques during exhalation. The technique requires training, concentration and effort from the individual. It is important to systematically review the evidence demonstrating that autogenic drainage is an effective intervention for people with cystic fibrosis. To compare the clinical effectiveness of autogenic drainage in people with cystic fibrosis with other physiotherapy airway clearance techniques. We searched the Cochrane Cystic Fibrosis Trials Register, compiled from electronic database searches and handsearching of journals and conference abstract books. We also searched the reference lists of relevant articles and reviews, as well as two trials registers (31 August 2017).Dtae of most recent search of the Cochrane Cystic Fibrosis Trials Register: 25 September 2017. We identified randomised and quasi-randomised controlled studies comparing autogenic drainage to another airway clearance technique or no therapy in people with cystic fibrosis for at least two treatment sessions. Data extraction and assessments of risk of bias were independently performed by two authors. The authors assessed the quality of the evidence using the GRADE system. The authors contacted two investigators for further information pertinent to their published studies. Searches retrieved 35 references to 21 individual studies, of which seven (n = 208) were eligible for inclusion. One study was of parallel design with the remaining six being cross-over in design; participant numbers ranged from 17 to 75. The total study duration varied between four days and two years. The age of participants ranged between seven and 63 years with a wide

    To determine the serum hyaluronic acid (HA) levels as biochemical marker of hepatic fibrosis and cirrhosis and correlate it with the degree of hepatic fibrosis and cirrhosis. This study was performed on 100 patients of chronic liver disease whose liver biopsies had been carried out. Fifty healthy controls were also included in the study. Routine liver function tests, hepatitis serology and serum hyaluronic acid levels were carried out on patients and controls. Liver biopsy of 100 patients revealed that 21 were in stage 0 fibrosis, 38 in stage 1 fibrosis, 26 in stage 3 fibrosis and 15 in stage 4 fibrosis. Mean Serum HA (mean +- SD) concentration in patients were 189 +- 98 mg/L vs. 21 +- 10 mg/L of healthy controls. The difference observed was statistically significant (p < 0.001). Patients in stage 4 fibrosis had significantly higher (p <0.001) mean serum HA concentration as compared to other stages of liver fibrosis. Diagnostic accuracy of serum HA at marginally elevated level of 60 mg/L determined the sensitivity 78.4 %, specificity 80.9%, positive predicted value 93.9% and negative predicted value of 50%. Serum HA is a useful non-invasive marker of liver fibrosis. There is a strong positive correlation between serum HA levels and degree of liver fibrosis. The concentration of serum HA rises according to progression of liver fibrosis and levels are highest in patients with liver cirrhosis. (author)

    The progression of liver fibrosis changes the biomechanical properties of liver tissue. This study characterized and compared different liver fibrosis stages in rats in terms of viscoelasticity. Three viscoelastic models, the Voigt, Maxwell, and Zener models, were applied to experimental data from rheometer tests and then the elasticity and viscosity were estimated for each fibrosis stage. The study found that both elasticity and viscosity are correlated with the various stages of liver fibrosis. The study revealed that the Zener model is the optimal model for describing the mechanical properties of each fibrosis stage, but there is no significant difference between the Zener and Voigt models in their performance on liver fibrosis staging. Therefore the Voigt model can still be effectively used for liver fibrosis grading. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Objective: To observe the effect of Ganfukang on liver function and serum hepatic fibrosis markers levels in SD rats with experimental hepatic fibrosis. Methods: SD rat models of liver fibrosis was induced by CCl 4 (n=57). Liver function (GPT, GOT) and serum hepatic fibrosis markers levels (HA, LN, C-IV, PC-III, with RIA) were tested in these models and 10 control rats. Eleven model rats were left untreated, the others were treated with Ganfukang of different concentrations and the above hepatic parameters were again determined after completion of treatment. Results: Lever function was much deteriorated and serum markers levels significantly increased in the model rats (vs controls, P<0.01). After treatment with Ganfukang, the improvement was significant (vs untreated models, P<0.01). Conclusion: Ganfukang is of definite therapeutic value for experimental hepatic fibrosis in rat models.

    Full Text Available This article analyses the emergence of “leaders” of the Chinese community in Madrid, based on a study of a conflict that was brief but significant; specifically, the social protests carried out by shopkeepers and workers in the central district of Lavapiés in 2005 and 2006, and who were protesting against a controversial municipal regulations on trade. What is interesting about this study is the way that it analyses – through this experience of the mobilisation and representation of their community – the way in which these “leaders” were constituted as political entities, with links to the main relevant social actors (associationist movements, political parties and economic groups in Madrid and how they co-opted a certain ability to represent the collective by incorporating such complex, symbolic elements as “being Chinese”, social class, affiliation to local parties and discourses on belonging to the welcoming country. The analysis shows, furthermore, that the various expressions of ethnicity do not represent a fixed, inert reality, but rather a dynamic process which, in addition to the actual paths of the main characters, takes shape based on the context in which it is immersed.

    Full Text Available This paper offers an approach to the study of skateboarding in the city of Madrid through a multi-sited ethnographic study which combines online and offline research. Based on this methodology, we show an analysis of some of the main characteristics of the skate culture in our society, particularly in the city of Madrid, putting the emphasis on the most intersubjective and cultural aspects of this reality. In recent years skateboarding has experienced a visible increase in Madrid and the analytic frame that we propose for studying its diffusion and escalation, answers to changes in the cultural order of western societies and the skate culture in itself, in dynamic interdependence with the economic sphere, as the order of production and distribution of cultural and sporting services and goods.

    Full Text Available Idiopathic pulmonary fibrosis is a progressive and lethal form of interstitial lung disease that lacks effective therapies at present. Glycyrrhizic acid (GA, a natural compound extracted from a traditional Chinese herbal medicine Glycyrrhiza glabra, was recently reported to benefit lung injury and liver fibrosis in animal models, yet whether GA has a therapeutic effect on pulmonary fibrosis is unknown. In this study, we investigated the potential therapeutic effect of GA on pulmonary fibrosis in a rat model with bleomycin (BLM-induced pulmonary fibrosis. The results indicated that GA treatment remarkably ameliorated BLM-induced pulmonary fibrosis and attenuated BLM-induced inflammation, oxidative stress, epithelial-mesenchymal transition and activation of tansforming growth factor-beta signaling pathway in the lungs. Further, we demonstrated that GA treatment inhibited proliferation of 3T6 fibroblast cells, induced cell cycle arrest and promoted apoptosis in vitro, implying that GA-mediated suppression of fibroproliferation may contribute to the anti-fibrotic effect against BLM-induced pulmonary fibrosis. In summary, our study suggests a therapeutic potential of GA in the treatment of pulmonary fibrosis.

    Non-alcoholic fatty liver disease (NAFLD) has become one of the most frequent causes of chronic liver disease. Currently, therapeutic options for NAFLD patients are limited, but new pharmacologic agents are being investigated in the course of clinical trials. Because most of these studies are focusing on patients with fibrosis stages II and III (according to Kleiner), non-invasive identification of patients with intermediate fibrosis stages (II and III) is of increasing interest. Evaluation of NAFLD Fibrosis Score (NFS) and liver stiffness measurement (LSM) for prediction of fibrosis stages II/III. Patients with histologically confirmed NAFLD diagnosis were included in the study. All patients underwent a clinical and laboratory examination as well as a LSM prior to liver biopsy. Predictive value of NFS and LSM with respect to identification of fibrosis stages II/III was assessed. 134 NAFLD patients were included and analyzed. Median age was 53 (IQR 36 - 60) years, 55 patients (41 %) were female. 82 % of our patients were overweight/obese with typical aspects of metabolic syndrome. 84 patients (66 %) had liver fibrosis, 42 (50 %) advanced fibrosis. LSM and NFS correlated with fibrosis stage (r = 0.696 and r = 0.685, respectively; p stages II/III. If both criteria were met, probability of fibrosis stage II/III was 61 %. If none of the two criteria was met, chance for fibrosis stage II/III was only 6 % (negative predictive value 94 %). Combination of LSM and NFS enables identification of patients with significant probability of fibrosis stage II/III. Accordingly, these tests, especially in combination, may be a suitable screening tool for fibrosis stages II/III in NAFLD. The use of these non-invasive methods might also help to avoid unnecessary biopsies. © Georg Thieme Verlag KG Stuttgart · New York.

    To analyze the available information about continuous subcutaneous insulin infusion (CSII) and continuous glucose monitoring (CGM) systems in the public health care system of the Community of Madrid. A survey consisting of 31 items was sent to the 28 endocrinology department of the Madrid public hospitals. Items focused on CSII and CGM and included patients' registrations, as well as data regarding healthcare, administrative, and logistic aspects. Responses from a total of 20 hospitals where these procedures are used were received from March 2013 to May 2014. Data about pediatric patients were obtained from adult endocrinology departments, except for two hospitals which directly reported the information. A total of 1256 CSII pumps were recorded in the Madrid region, of which 1089 were used by adults, and the remaining 167 by pediatric patients. During 2013, 151 new CSII systems were implanted (12% of the total), while 14 pumps were withdrawn. Availability of human resources (medical assistance) and the number of staff practitioners experienced in management of these systems widely varied between hospitals. Eighty-five percent of hospitals used retrospective CGM systems, and 40% routinely placed them before starting an insulin pump. Thirteen hospitals (65%) used long-term, real-time CGM systems in selected cases (a total of 67 patients). Use of these technologies in diabetes is unequal between public health care hospitals in Madrid, and is still significantly lower as compared to other countries with similar incomes. However, there appears to be a trend to an increase in their use. Copyright © 2014 SEEN. Published by Elsevier España, S.L.U. All rights reserved.

    Over the previous 50 years survival of patients with cystic fibrosis has progressively increased. As a result of improvements in health care, increasing numbers of patients with cystic fibrosis are now considering starting families of their own. For the health care professionals who look after these patients, the assessment of the potential risks, and the process of guiding prospective parents through pregnancy and beyond can be both challenging and rewarding. To facilitate appropriate discussions about pregnancy, health care workers must have a detailed understanding of the various important issues that will ultimately need to be considered for any patient with cystic fibrosis considering parenthood. This review will address these issues. In particular, it will outline pregnancy outcomes for mothers with cystic fibrosis, issues that need to be taken into account when planning a pregnancy and the management of pregnancy for mothers with cystic fibrosis or mothers who have undergone organ transplantation as a result of cystic fibrosis.

    Recurrent fibrosis after liver transplantation (LT) impacts on long-term graft and patient survival. We performed a meta-analysis to compare the accuracy of non-invasive methods to diagnose significant recurrent fibrosis (stage F2-F4) following LT. Studies comparing serum fibrosis biomarkers, namely AST-to-platelet ratio index (APRI), fibrosis score 4 (FIB-4), or transient elastography (TE) with liver biopsy in LT recipients were systematically identified through electronic databases. In the meta-analysis, we calculated the weighted pooled odds ratio and used a fixed effect model, as there was no significant heterogeneity between studies. Eight studies were included for APRI, four for FIB-4, and twelve for TE. The mean prevalence of significant liver fibrosis was 37.4%. The summary odds ratio was significantly higher for TE (21.17, 95% CI confidence interval 14.10-31.77, p = 1X10-30) as compared to APRI (9.02, 95% CI 5.79-14.07; p = 1X10-30) and FIB-4 (7.08, 95% CI 4.00-12.55; p = 1.93X10-11). In conclusion, TE performs best to diagnose recurrent fibrosis in LT recipients. APRI and FIB-4 can be used as an estimate of significant fibrosis at centres where TE is not available. Longitudinal assessment of fibrosis by means of these non-invasive tests may reduce the need for liver biopsy.

    Full Text Available Fibrosis is the formation of fibrous connective tissue in response to injury. It is characterized by the accumulation of extracellular matrix components, particularly collagen, at the site of injury. Fibrosis is an adaptive response that is a vital component of wound healing and tissue repair. However, its continued activation is highly detrimental and a common final pathway of numerous disease states including cardiovascular and respiratory disease. Worldwide, fibrotic diseases cause over 800,000 deaths per year, accounting for ~45% of total deaths. With an aging population, the incidence of fibrotic disease and subsequently the number of fibrosis-related deaths will rise further. Although, fibrosis is a well-recognized cause of morbidity and mortality in a range of disease states, there are currently no viable therapies to reverse the effects of chronic fibrosis. Numerous predisposing factors contribute to the development of fibrosis. Biological aging in particular, interferes with repair of damaged tissue, accelerating the transition to pathological remodeling, rather than a process of resolution and regeneration. When fibrosis progresses in an uncontrolled manner, it results in the irreversible stiffening of the affected tissue, which can lead to organ malfunction and death. Further investigation into the mechanisms of fibrosis is necessary to elucidate novel, much needed, therapeutic targets. Fibrosis of the heart and lung make up a significant proportion of fibrosis-related deaths. It has long been established that the heart and lung are functionally and geographically linked when it comes to health and disease, and thus exploring the processes and mechanisms that contribute to fibrosis of each organ, the focus of this review, may help to highlight potential avenues of therapeutic investigation.

    Globally, about five per cent of children are born with congenital or genetic disorders. The most common autosomal recessive conditions are thalassaemia, sickle cell disease, cystic fibrosis and Tay-Sachs disease, with higher carrier rates in specific patient populations. Identifying and counselling couples at genetic risk of the conditions before pregnancy enables them to make fully informed reproductive decisions, with some of these choices not being available if genetic counselling is only offered in an antenatal setting. This is an update of a previously published review. To assess the effectiveness of systematic preconception genetic risk assessment to improve reproductive outcomes in women and their partners who are identified as carriers of thalassaemia, sickle cell disease, cystic fibrosis and Tay-Sachs disease in healthcare settings when compared to usual care. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group's Trials Registers. In addition, we searched for all relevant trials from 1970 (or the date at which the database was first available if after 1970) to date using electronic databases (MEDLINE, Embase, CINAHL, PsycINFO), clinical trial databases (National Institutes of Health, Clinical Trials Search portal of the World Health Organization, metaRegister of controlled clinical trials), and hand searching of key journals and conference abstract books from 1998 to date (European Journal of Human Genetics, Genetics in Medicine, Journal of Community Genetics). We also searched the reference lists of relevant articles, reviews and guidelines and also contacted subject experts in the field to request any unpublished or other published trials.Date of latest search of the registers: 20 June 2017.Date of latest search of all other sources: 16 November 2017.

    Full Text Available Las mujeres componen el 65% de la inmigración brasileña en España. Esta feminización del flujo migratorio se vincula a la transformación de las relaciones de género vividas por estas mujeres en Brasil y en la sociedad de acogida. En Madrid, observamos una gran cantidad de negocios regentados por brasileñas - pequeños emprendimientos del campo de la hostelería o de estética y belleza. Sin embargo, ellas son más comúnmente empleadas en sectores no calificados con baja remuneración - en general relacionados a los servicios domésticos y al cuidado de niños y ancianos y la prostitución - , siendo en muchos casos asociadas a un estereotipo de hipersexualidad que influencia los nichos económicos a los que pueden o no acceder. El presente artículo analiza el rol económico que estas mujeres ocupan, y el conjunto de estereotipos raciales/nacionales con los cuales dialogan para lograr construir su inserción económica en España.The Brazilian women correspond to 65% of the Brazilian immigrants in Spain. This feminization of the displacement is deeply related with a change of the gender relations lived by these women both in Brazil and in host society. In Madrid, Brazilian women are protagonists of a new kind of entrepreneurship. They run small businesses in the field of restoration and of aesthetics and beauty. Nevertheless, they are most commonly employed in low-paid jobs, generally related with domestic services and child/elder care, and with prostitution - being in many cases associated with a stereotype of hyper-sexuality that influences the economic niches they can or can't access. The aim of this paper is to analyze the economic roles of Brazilian immigrants in Madrid, also discussing the imaginaries of the host society with which they dialog to make their economic insertion feasible in Spain.

    Full Text Available BACKGROUND AND AIMS: The PNPLA3 I148M sequence variant favors hepatic lipid accumulation and confers susceptibility to hepatic fibrosis and hepatocellular carcinoma. The aim of this study was to estimate the effect size of homozygosity for the PNPLA3 I148M variant (148M/M on the fibrosis progression rate (FPR and the interaction with age at infection in chronic hepatitis C (CHC. METHODS: FPR was estimated in a prospective cohort of 247 CHC patients without alcohol intake and diabetes, with careful estimation of age at infection and determination of fibrosis stage by Ishak score. RESULTS: Older age at infection was the strongest determinant of FPR (p<0.0001. PNPLA3 148M/M was associated with faster FPR in individuals infected at older age (above the median, 21 years; -0.64±0.2, n = 8 vs. -0.95±0.3, n = 166 log10 FPR respectively; p = 0.001; confirmed for lower age thresholds, p<0.05, but not in those infected at younger age (p = ns. The negative impact of PNPLA3 148M/M on fibrosis progression was more marked in subjects at risk of altered hepatic lipid metabolism (those with grade 2-3 steatosis, genotype 3, and overweight; p<0.05. At multivariate analysis, PNPLA3 148M/M was associated with FPR (incremental effect 0.08±0.03 log10 fibrosis unit per year; p = 0.022, independently of several confounders, and there was a significant interaction between 148M/M and older age at infection (p = 0.025. The association between 148M/M and FPR remained significant even after adjustment for steatosis severity (p = 0.032. CONCLUSIONS: We observed an interaction between homozygosity for the PNPLA3 I148M variant and age at infection in determining fibrosis progression in CHC patients.

  14. TGF-β/Smad signaling in renal fibrosis

    2015-03-01

    Full Text Available TGF-β (transforming growth factor-β is well identified as a central mediator in renal fibrosis. TGF-β initiates canonical and non-canonical pathways to exert multiple biological effects. Among them, Smad signaling is recognized as a major pathway of TGF- signaling in progressive renal fibrosis. During fibrogenesis, Smad3 is highly activated, which is associated with the down-regulation of an inhibitory Smad7 via an ubiquitin E3-ligases-dependent degradation mechanism. The equilibrium shift between Smad3 and Smad7 leads to accumulation and activation of myofibroblasts, overproduction of ECM (extracellular matrix, and reduction in ECM degradation in the diseased kidney. Therefore, overexpression of Smad7 has been shown to be a therapeutic agent for renal fibrosis in various models of kidney diseases. In contrast, another downstream effecter of TGF-β/Smad signaling pathway, Smad2, exerts its renal protective role by counter-regulating the Smad3. Furthermore, recent studies demonstrated that Smad3 mediates renal fibrosis by down-regulating miR-29 and miR-200 but up-regulating miR-21 and miR-192. Thus, overexpression of miR-29 and miR-200 or down-regulation of miR-21 and miR-192 is capable of attenuating Smad3-mediated renal fibrosis in various mouse models of chronic kidney diseases. Taken together, TGF-/Smad signaling plays an important role in renal fibrosis. Targeting TGF-β/Smad3 signaling may represent a specific and effective therapy for chronic kidney diseases associated with renal fibrosis.

    Heritage conservation has a great impact on the economy of a country. The enhancement of archaeological sites is an investment that promotes tourism and culture. The interdisciplinary knowledge of heritage should be the basis of its management. Preventive actions, non-destructive analytical techniques and monitoring for the conservation of these assets should be promoted. "El Risco de las Cuevas" is a highly decayed and nearly vertical gypsum escarpment which contains a series of dwellings excavated during the Chalcolithic and much more recent times. It is located at Perales de Tajuña, 40 km southeast of Madrid, Spain. This monument is approximately 70 metres high and 500 metres wide. It was listed as a cultural and monumental heritage site by the regional government of Madrid in 1998. The gypsum escarpment housing the dwellings forms part of a lower Miocene unit (Madrid Basin). Debris cones with a mixture of debris from the lower, medium and upper units are found at the bottom of the rockwall. The vulnerability of this monument to atmospheric agents has been studied using "in situ" monitoring techniques of humidity, temperature and rate of rockfalls. Drones have been used for aerial photography in the highest areas of the escarpment and have provided an information network of fractures likely to cause rockfall. Gypsum artificial accelerated ageing has been carried out in the laboratory, including freeze/thaw, wet/dry, thermal shock and dissolution tests. To determine the response of these accelerated ageing processes, density, micro-roughness, ultrasound velocities (Vp and Vs), air permeability and microscopy measurements were made before, during and after ageing tests. Geomorphological studies, rates of decay, material characteristics and durability tests indicate that the decay is controlled by the mineralogy, clay content and porosity of the gypsum rock, as well as microclimate, temperature changes and rock fractures. Rockfalls are particularly relevant in the

    Most people with cystic fibrosis (80% to 90%) need pancreatic enzyme replacement therapy to prevent malnutrition. Enzyme preparations need to be taken whenever food is taken, and the dose needs to be adjusted according to the food consumed. A systematic review on the efficacy and safety of pancreatic enzyme replacement therapy is needed to guide clinical practice, as there is variability between centres with respect to assessment of pancreatic function, time of commencing treatment, dose and choice of supplements. This is an updated version of a published review. To evaluate the efficacy and safety of pancreatic enzyme replacement therapy in children and adults with cystic fibrosis and to compare the efficacy and safety of different formulations of this therapy and their appropriateness in different age groups. Also, to compare the effects of pancreatic enzyme replacement therapy in cystic fibrosis according to different diagnostic subgroups (e.g. different ages at introduction of therapy and different categories of pancreatic function). We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register comprising references identified from comprehensive electronic database searches and handsearches of relevant journals and abstract books of conference proceedings. Most recent search: 15 July 2016.We also searched an ongoing trials website and the websites of the pharmaceutical companies who manufacture pancreatic enzyme replacements for any additional trials. Most recent search: 22 July 2016. Randomised and quasi-randomised controlled trials in people of any age, with cystic fibrosis and receiving pancreatic enzyme replacement therapy, at any dosage and in any formulation, for a period of not less than four weeks, compared to placebo or other pancreatic enzyme replacement therapy preparations. Two authors independently assessed trials and extracted outcome data. They also assessed the risk of bias of the trials included in the review. One

    Idiopathic pulmonary fibrosis (IPF) is a chronic and progressive interstitial lung disease with unknown etiology and undefined treatment modality. Fibroblasts are regarded as the major cell type that mediates the onset and progression of lung fibrosis by secreting large amounts of extracellular matrix (ECM) proteins, such as connective tissue growth factor (CTGF/CCN2). Current knowledge confers a crucial role of CCN2 in lung fibrosis. CCN5, another member of the CCN family, has been suggested to play an inhibitory role in some fibrotic diseases, such as cardiac fibrosis. However, the role of CCN5 in the process of IPF remains unknown. In the present study, using western blot analysis, we demonstrate that CCN2 is highly expressed in fibroblasts derived from IPF tissue, but is only slightly expressed in normal human lung fibroblasts. However, CCN5 was weakly expressed in all the above cells. qRT-PCR revealed that transforming growth factor (TGF)-β1 stimulation increased CCN2 expression in the IPF-derived cultures of primary human lung fibroblasts (PIFs) in a time- and concentration-dependent manner, but only slightly affected the expression of CCN5. The overexpression of CCN5 induced by the transfection of PIFs with recombinant plasmid did not affect cell viability, proliferation and apoptosis; however, it significantly suppressed the expression of CCN2, α-smooth muscle actin (α-SMA) and collagen type I. The TGF-β1-induced upregulation of the phosphorylation of Akt was reversed by CCN5 overexpression. Our results also demonstrated that adenovirus-mediated CCN5 overexpression in a mouse model of bleomycin-induced IPF significantly decreased the hydroxyproline content in the lungs, as well as TGF-β1 expression in bronchoalveolar lavage fluid. Taken together, our data demonstrate that CCN5 exerts an inhibitory effect on the fibrotic phenotypes of pulmonary fibroblasts in vitro and in vivo, and as such may be a promising target for the treatment of IPF.

    Inhaled administration of high doses of aminoglycosides is a key maintenance treatment of Pseudomonas aeruginosa chronic respiratory infections in cystic fibrosis (CF). We analyzed the dynamics and mechanisms of stepwise high-level tobramycin resistance development in vitro and compared the results with those of isogenic pairs of susceptible and resistant clinical isolates. Resistance development correlated with fusA1 mutations in vitro and in vivo. pmrB mutations, conferring polymyxin resistance, were also frequently selected in vitro In contrast, mutational overexpression of MexXY, a hallmark of aminoglycoside resistance in CF, was not observed in in vitro evolution experiments.

Information about knowledge, comprehension, perception and use of traffic light labelling (TLL was collected. Analyses examined the frequency of the variables of interest. Differences were tested using the χ2 test.Results: The response rate was 80.6% (first phase and 97.8% (second phase. Consumers that knew the TLL and understood its color-coding system were 41.4% and 18.6% respectively. From the participants that knew the TLL system, 61.5% thought it was very useful (80% among those >65 years and 90% among those with primary studies; p>0.05. Just 31.4% of consumers habitually used TLL to buy their products (70% among those with primary studies; p=0.04. This percentage was higher in consumers that understood the color-coding system (second phase (66.6%; p<0.01.Conclusions: The level of TLL’s knowledge and comprehension was low. Consumers that know TLL, consider it a useful nutrition instrument. Those who understand, use it habitually to buy their products, especially consumers older than 65 years old and with primary studies. A widespread introduction of this system in Spain might contribute to improve food and eating habits, especially elderly people and less educated.

    Full Text Available Congenital hepatic fibrosis is characterized by a ductal plate malformation with duct-like structures and fibrosis. It manifests clinically with portal hypertension and may be associated with multiple congenital defects. We present the case of a 16-year-old male with splenomegaly, leukopenia and thrombocytopenia, esophageal varices, and a histopathological diagnosis of congenital hepatic fibrosis. He exhibits "café au lait' spots and "Lisch' nodules, with a diagnosis of von Recklinghausen's disease. Congenital hepatic fibrosis belongs to the so-called fibropolycystic diseases, in which there is a disordered interaction between cells and the extracellular matrix. Von Recklinghausen's disease affects tissues derived from the neural crest and its diagnosis is based on clinical criteria. It is associated with multiple diseases. We describe its association with congenital hepatic fibrosis for the first time.La fibrosis hepática congénita se origina como consecuencia de una malformación de la placa ductal con estructuras tipo ductales acompañadas de fibrosis. Se manifiesta con hipertensión portal y puede asociarse a múltiples defectos congénitos. Presentamos un varón de 16 años con esplenomegalia, leuco- y plaquetopenia, varices esofágicas y diagnóstico histopatológico de fibrosis hepática congénita. La exploración física mostraba la existencia de manchas de "café con leche' y nódulos de "Lisch' con diagnóstico de enfermedad de von Recklinghausen. La fibrosis hepática congénita forma parte de las enfermedades fibropoliquísticas donde existiría una alteración en la interacción entre las células y la matriz extracelular. La enfermedad de von Recklinghausen afecta a los tejidos derivados de la cresta neural y su diagnóstico se basa en criterios clínicos. Se asocia a múltiples patologías. Presentamos por primera vez su asociación con fibrosis hepática congénita.

    Full Text Available Uno de los objetivos del Estudio Multicéntrico sobre Actitudes y Normas Culturales frente a la Violencia (proyecto ACTIVA es analizar la relación entre las actitudes favorecedoras de la violencia y las conductas violentas. En el presente artículo se estudia la relación entre actitudes autoritarias y dos componentes de la violencia: su justificación y su realización efectiva. La recolección de datos se hizo en la ciudad de Madrid entre octubre y diciembre de 1996. Se trabajó con una muestra representativa de 1 219 personas entrevistadas en sus domicilios a partir del cuestionario común del proyecto ACTIVA, al cual se añadieron algunas preguntas. Globalmente considerada, la muestra tuvo una puntuación baja en la escala de autoritarismo. El grupo de personas que más justificaron la violencia tuvo puntuaciones más altas en autoritarismo, al igual que las personas en cuyas conductas habituales se observó un nivel de agresión mayor. Las actitudes más autoritarias se constataron en barrios de bajos recursos económicos, en personas no activas laboralmente, en las de nivel educativo más bajo y en las que se identificaron con una ideología de derecha. Si los más autoritarios justifican y ejercen más la violencia, es preciso fomentar actitudes de crítica hacia quienes abusan del poder y respeto por las diferencias, a fin de prevenir la aparición de estas conductas, sin olvidar la influencia de las variables sociales mencionadas anteriormente.One of the objectives of the Multicentric Study on Cultural Norms and Attitudes Toward Violence (Estudio Multicéntrico sobre Actitudes y Normas Culturales frente a la Violencia, the ACTIVA project is to analyze the relationship between those attitudes that foster violence and the violent behaviors themselves.

    Full Text Available Abstract Background Malaria in pregnancy is associated with maternal and foetal morbidity and mortality in endemic areas, but information on imported cases to non-endemic areas is scarce. The aim of this study was to describe the clinical and epidemiological characteristics of malaria in pregnancy in two general hospitals in Madrid, Spain. Methods Retrospective descriptive study of laboratory-confirmed malaria in pregnant women at the Fuenlabrada University Hospital and the Príncipe de Asturias University Hospital, in Madrid, over a six- and 11-year period, respectively. Relevant epidemiological, clinical and laboratory data was obtained from medical records. Results There were 19 pregnant women among 346 malaria cases (5.4%. The average age was 27 years. The gestational age (trimester was: 53% 3rd, 31% 1st, 16% 2nd. All but one were multigravidae. Three were HIV positive. All were sub-Saharan immigrants: two were recently arrived immigrants and seventeen (89% had visited friends and relatives. None had taken prophylaxis nor seeked pre-travel advice. Presentation: 16 symptomatic patients (fever in fourteen, asthenia in two, three asymptomatic. Median delay in diagnosis: 7.5 days. Laboratory tests: anaemia (cut off Hb level 11 g/dl 78.9% (mild 31.6%, moderate 31.6%, severe 15.8% thrombocytopaenia 73.7%, hypoglycaemia 10.5%. All cases were due to Plasmodium falciparum, one case of hyperparasitaemia. Quinine + clindamycin prescribed in 84%. Outcomes: no severe maternal complications or deaths, two abortions, fifteen term pregnancies, no low-birth-weight newborns, two patients were lost to follow-up. Conclusions Though cases of malaria in pregnancy are uncommon, a most at risk group is clearly defined: young sub-Saharan mothers visiting friends and relatives without pre-travel counselling and recently-arrived immigrants. The most common adverse maternal and foetal effects were anaemia and stillbirth. Given that presentation can be asymptomatic

    Full Text Available A major issue with Schistosoma mansoni infection is the development of periportal fibrosis, which is predominantly caused by the host immune response to egg antigens. Experimental studies have pointed to the participation of monocytes in the pathogenesis of liver fibrosis. The aim of this study was to characterize the subsets of monocytes in individuals with different degrees of periportal fibrosis secondary to schistosomiasis. Monocytes were classified into classical (CD14++CD16−, intermediate (CD14++CD16+, and nonclassical (CD14+CD16++. The expressions of monocyte markers and cytokines were assessed using flow cytometry. The frequency of classical monocytes was higher than the other subsets. The expression of HLA-DR, IL-6, TNF-α, and TGF-β was higher in monocytes from individuals with moderate to severe fibrosis as compared to other groups. Although no differences were observed in receptors expression (IL-4R and IL-10R between groups of patients, the expression of IL-12 was lower in monocytes from individuals with moderate to severe fibrosis, suggesting a protective role of this cytokine in the development of fibrosis. Our data support the hypothesis that the three different monocyte populations participate in the immunopathogenesis of periportal fibrosis, since they express high levels of proinflammatory and profibrotic cytokines and low levels of regulatory markers.

    Rounds, Sharon I. S.

    2012-01-01

    There is increasing clinical, radiologic, and pathologic recognition of the coexistence of emphysema and pulmonary fibrosis in the same patient, resulting in a clinical syndrome known as combined pulmonary fibrosis and emphysema (CPFE) that is characterized by dyspnea, upper-lobe emphysema, lower-lobe fibrosis, and abnormalities of gas exchange. This syndrome frequently is complicated by pulmonary hypertension, acute lung injury, and lung cancer. The CPFE syndrome typically occurs in male smokers, and the mortality associated with this condition, especially if pulmonary hypertension is present, is significant. In this review, we explore the current state of the literature and discuss etiologic factors and clinical characteristics of the CPFE syndrome. PMID:22215830

    Full Text Available The aim of this study is to compare climatic conditions between the interior of the Iberian Peninsula and the southeastern coast of Spain. The article analyzes selected elements of climate over the last 15 years (2000-2014. Synoptic data from airport meteorological stations in Madrid Barajas and Alicante Elche were used. Attention was focused on annual air temperature, relative humidity and precipitation. The mean climatic conditions over the period 2000-2014 were compared with those over the 1961-1990 period which is recommended by WMO as climate normal and with data for the 1971-2000 coming from ‘Climate Atlas’ of Spanish meteorologists group AEMET. Two of climate elements discussed were characterized by significant changes. The annual air temperature was higher by about 0.2°C in Alicante and 0.9°C in Madrid in the period 2000-2014 compared to the 1961-1990. The current winters were colder than in years 1961-1990 at both stations. Gradual decrease in annual precipitation totals was observed at both stations. In 1961-1990 the annual average precipitation in Madrid amounted to 414 mm, while in Alicante it was 356 mm. However, in the recent years of 2000-2014 these totals were lower compared to 1961-1990 reaching 364.1 mm in the central part of Spain and 245.7 mm on the south-western coast.

    Several comparable mechanisms have been identified for hepatic and pulmonary fibrosis. The human microfibrillar associated glycoprotein 4 (MFAP4), produced by activated myofibroblasts, is a ubiquitous protein playing a potential role in extracellular matrix (ECM) turnover and was recently identified as biomarker for hepatic fibrosis in hepatitis C patients. The current study aimed to evaluate serum levels of MFAP4 in patients with pulmonary fibrosis in order to test its potential as biomarker in clinical practice. A further aim was to determine whether MFAP4 deficiency in mice affects the formation of pulmonary fibrosis in the bleomycin model of lung fibrosis. 91 patients with idiopathic pulmonary fibrosis (IPF), 23 with hypersensitivity pneumonitis (HP) and 31 healthy subjects were studied. In the mouse model, C57BL/6 Mfap4+/+ and Mfap4-/- mice between 6-8 weeks of age were studied. Serum levels of MFAP4 were measured by ELISA in patients and in mice. Surfactant protein D (SP-D) and LDH were measured as comparison biomarkers in patients with pulmonary fibrosis. Morphometric assessment and the Sircol kit were used to determine the amount of collagen in the lung tissue in the mouse model. Serum levels of MFAP4 were not elevated in lung fibrosis - neither in the patients with IPF or HP nor in the animal model. Furthermore no significant correlations with pulmonary function tests of IPF patients could be found for MFAP4. MFAP4 levels were increased in BAL of bleomycin treated mice with pulmonary fibrosis. MFAP4 is not elevated in sera of patients with pulmonary fibrosis or bleomycin treated mice with pulmonary fibrosis. This may be due to different pathogenic mechanisms of liver and lung fibrogenesis. MFAP4 seems to be useful as serum biomarker for hepatic but not for lung fibrosis.

    2015-01-01

    Cystic fibrosis is the most common fatal inherited autosomal recessive disease in Caucasians, affecting approximately one out of every 2,000 births. Survival of patients with cystic fibrosis has significantly improved due to advances in respiratory and nutritional care, and their current average life expectancy is 30-40 years. Development of cystic fibrosis-related diabetes is a comorbidity that increases with age and may reach a prevalence up to 50% in adults. Its development is associated to impaired lung function and nutritional status, and early diagnosis and treatment are therefore essential to improve quality of life and performance status. Insulin therapy for diabetes and other early carbohydrate metabolism disorders may improve lung function and nutritional status of patients with cystic fibrosis. Copyright © 2014 SEEN.

    Suspended particles are a very complex type of atmospheric pollution because of their chemical composition and size. In fact, there are a quite high number of particles sources which are linked to different physico-chemical processes that determine their size. At present particles smaller than 10 {mu}m are considered the most dangerous, as has been recently pointed out by numerous epidemiologic studies. In this way, more restrictive concentration limit values have been approved in the EU countries, so an assessment of present airborne concentration values and the sources apportionment in their most representative areas is needed. In the Madrid Community a first approaching of these and other aims, has been carried out from an analysis of the Madrid Air Quality networks data. This will contribute to the stablishment of concentration levels abatement strategies. (Author) 111 refs.

    Small animal models of lung fibrosis are essential for unraveling the molecular mechanisms underlying human fibrotic lung diseases; additionally, they are useful for preclinical testing of candidate antifibrotic agents. The current end-point measures of experimental lung fibrosis involve labor-intensive histological and biochemical analyses. These measures fail to account for dynamic changes in the disease process in individual animals and are limited by the need for large numbers of animals for longitudinal studies. The emergence of noninvasive imaging technologies provides exciting opportunities to image lung fibrosis in live animals as often as needed and to longitudinally track the efficacy of novel antifibrotic compounds. Data obtained by noninvasive imaging provide complementary information to histological and biochemical measurements. In addition, the use of noninvasive imaging in animal studies reduces animal usage, thus satisfying animal welfare concerns. In this article, we review these new imaging modalities with the potential for evaluation of lung fibrosis in small animal models. Such techniques include micro-computed tomography (micro-CT), magnetic resonance imaging, positron emission tomography (PET), single photon emission computed tomography (SPECT), and multimodal imaging systems including PET/CT and SPECT/CT. It is anticipated that noninvasive imaging will be increasingly used in animal models of fibrosis to gain insights into disease pathogenesis and as preclinical tools to assess drug efficacy.

    Full Text Available The Th2 immune response in chronic schistosomiasis is associated with the development of periportal fibrosis. However, little is known about the phenotype and activation status of T cells in the process. Objective. To evaluate the profile of T cells in schistosomiasis patients with periportal fibrosis. Methods. It was a cross-sectional study, conducted in the village of Agua Preta, Bahia, Brazil, which included 37 subjects with periportal fibrosis determined by ultrasound. Peripheral blood mononuclear cells were obtained by the Ficcol-hypaque gradient and the frequency of T cells expressing the surface markers CD28, CD69, CD25, and CTLA-4 was determined by flow cytometry. Results. The frequency of CD4+CD28+ T lymphocytes was higher in individuals with moderate to severe fibrosis compared to patients with incipient fibrosis. We did not observe any significant difference in the frequency of CD4+ T cells expressing CD69 among groups of individuals. There was also no significant difference in the frequency of CD8+ T cells expressing CD28 or CD69 among the studied groups. Individuals with moderate to severe fibrosis presented a lower frequency of CD8+ T cells, CD4+CD25high T cells, and CD4+CTLA-4+ T cells when compared to patients without fibrosis or incipient fibrosis. The frequency of CD4+CD25low cells did not differ between groups. Conclusion. The high frequency of activated T cells coinciding with a low frequency of putative Treg cells may account for the development of periportal fibrosis in human schistosomiasis.

    Genetic counseling is an important part of health care in patients with cystic fibrosis or respiratory diseases associated with the CFTR (cystic fibrosis transmembrane conductance regulator) gene, including certain types of allergic bronchopulmonary aspergilloses or bronchial diseases (diffuse bronchiectasia). The basic goal is to provide patients with information on the transmission of cystic fibrosis and to asses the risk of recurrence. This risk is determined from molecular biology analyses examining the CFTR gene. Genotyping is the only means of screening for the heterozygous state, frequent in the French population (about 1/30). Because of the large number of mutated alleles not covered entirely by the genetic tests, there remains a question of probability expressed as a residual risk of a heterozygous state. A prenatal genotype diagnosis should be proposed to heterozygous couples who have a 25% risk of having a diseased child. Technically, this is almost always possible and the results are highly reliable. Nevertheless, there remains the risks related to sample taking and the ethical issue about which the patients must be informed. Management of these at risk couples who desire a child must be based on a multidisciplinary approach, particularly important when one of the parents has overt cystic fibrosis.

  3. Radiation pneumonitis and fibrosis

    Shopova, V.; Salovsky, P.; Dancheva, V.

    2001-01-01

    The likelihood of toxic pulmonary lesions development as the result of radiation therapy for pulmonary carcinoma and breast cancer is discussed. Two possible forms of radiation induced changes are described, namely: classical radiation pneumonitis (RP) terminating with lung fibrosis circumscribed in the radiation zone, and sporadic RP giving rise to bilateral lymphatic alveolitis and manifestations outside the irradiation field. Attention is called to the fact that chemotherapy augments the risk of toxic lung damage occurrence. A number of markers for early RP diagnosis, including lactate dehydrogenase activity, KL-6, procollagen III, transforming growth factor β, C-reactive protein and partial oxygen pressure are listed. Therapeutic possibilities in coping with RP and pulmonary fibrosis are assayed. Apart from the standard therapeutic approach using corticosteroids and azatioprin, ideas are set forth concerning the application of some antioxidants, angiotensin converting enzyme inhibitors and γ-interferon. It is pointed out that radiation pneumonitis and pulmonary fibrosis treatment has an essential practical bearing on life expectancy and quality of life in a great number of cancer patients. (author)

    In a retrospective study radiotherapy of breast fibrosis in hormone-treated men with histologically confirmed prostate carcinoma was examined. 10 patients had received hormones even before irradiation, 113 obtained hormone administration only after irradiation. The objective size of the glandular body and the overall size of the breast were measured with a special method developed by the author. 46 patients indicated complaints. With hypertrophic mamma and hypertrophic mamilla in 67 examined patients, 127 different symptoms resulted in total. Four patients of the group who had obtained hormones before irradiation, suffered from subjective symptoms. It resulted that radiotherapy of breast fibrosis carried out during hormone treatment is no gynecomastia prophylaxis, that already existent mamma hypertrophies are irreversible, but that existent sensations were notably reduced within 6 months after irradiation therapy. These results indicate the necessity of a radiotherapy of the mamma fibrosis before the hormone treatment is begun. Particularly in cases of higher operative risks, also the possibility of preferring radiotherapy to mastectomy should be fully utilized, in view of adequate or even better therapeutic results.

    Obstruction of the pancreatic duct can lead to pancreatic fibrosis. We investigated the correlation between the extent of pancreatic fibrosis and the postoperative exocrine and endocrine pancreatic function. Fifty-five patients who were treated for pancreatic and periampullary carcinoma and 19 patients with chronic pancreatitis were evaluated. Exocrine pancreatic function was evaluated by fecal elastase-1 test, while endocrine pancreatic function was assessed by plasma glucose level. The extent of fibrosis, duct dilation and endocrine tissue loss was examined histopathologically. A strong correlation was found between pancreatic fibrosis and elastase-1 level less than 100 microg/g (p pancreatic insufficiency. A strong correlation was found between pancreatic fibrosis and endocrine tissue loss (p pancreatic fibrosis nor endocrine tissue loss were correlated with the development of postoperative diabetes mellitus. Duct dilation alone was neither correlated with exocrine nor with endocrine function loss. The majority of patients develop severe exocrine pancreatic insufficiency after pancreatoduodenectomy. The extent of exocrine pancreatic insufficiency is strongly correlated with preoperative fibrosis. The loss of endocrine tissue does not correlate with postoperative diabetes mellitus. Preoperative dilation of the pancreatic duct per se does not predict exocrine or endocrine pancreatic insufficiency postoperatively. Copyright 2008 S. Karger AG, Basel.

  6. "Tipping" extracellular matrix remodeling towards regression of liver fibrosis

    Fibrosis development was initially conceived as an incessant progressive condition. Nowadays, it has become evident that fibrotic tissue undergoes a continuous two-way process: fibrogenesis and fibrinolysis, characterizing the remodeling of extracellular matrix (ECM). However, in established...... fibrosis, this two-way process is tipped towards fibrogenesis and this leads to a self-perpetuating accumulation of ECM, a distinct metabolic unit, together with other cells and processes promoting fibrosis deposition. Several mechanisms promote fibrosis regression, such as degradation of ECM, infiltration...

    Ultrafiltration failure is a major complication of long-term peritoneal dialysis, resulting in dialysis failure. Peritoneal fibrosis induced by continuous exposure to high glucose dialysate is the major contributor of ultrafiltration failure, for which there is no effective treatment. Overactivation of several signaling pathways, including transforming growth factor-β1 (TGF-β1) and platelet-derived growth factor (PDGF) pathways, contribute to the development of peritoneal fibrosis. Therefore, simultaneously blocking multiple signaling pathways might be a potential novel method of treating peritoneal fibrosis. Previously, we showed that core fucosylation, an important posttranslational modification of the TGF-β1 receptors, can regulate the activation of TGF-β1 signaling in renal interstitial fibrosis. However, it remains unclear whether core fucosylation affects the progression of peritoneal fibrosis. Herein, we show that core fucosylation was enriched in the peritoneal membrane of rats accompanied by peritoneal fibrosis induced by a high glucose dialysate. Blocking core fucosylation dramatically attenuated peritoneal fibrosis in the rat model achieved by simultaneously inactivating the TGF-β1 and PDGF signaling pathways. Next the protective effects of blocking core fucosylation and imatinib (a selective PDGF receptor inhibitor) on peritoneal fibrosis were compared and found to exhibit a greater inhibitory effect over imatinib alone, suggesting that blocking activation of multiple signaling pathways may have superior inhibitory effects on the development of peritoneal fibrosis. Thus, core fucosylation is essential for the development of peritoneal fibrosis by regulating the activation of multiple signaling pathways. This may be a potential novel target for drug development to treat peritoneal fibrosis. Copyright © 2018 International Society of Nephrology. Published by Elsevier Inc. All rights reserved.

  8. Shaded Relief and Radar Image with Color as Height, Madrid, Spain

    The white, mottled area in the right-center of this image from NASA's Shuttle Radar Topography Mission (SRTM) is Madrid, the capital of Spain. Located on the Meseta Central, a vast plateau covering about 40 percent of the country, this city of 3 million is very near the exact geographic center of the Iberian Peninsula. The Meseta is rimmed by mountains and slopes gently to the west and to the series of rivers that form the boundary with Portugal. The plateau is mostly covered with dry grasslands, olive groves and forested hills.Madrid is situated in the middle of the Meseta, and at an elevation of 646 meters (2,119 feet) above sea level is the highest capital city in Europe. To the northwest of Madrid, and visible in the upper left of the image, is the Sistema Central mountain chain that forms the 'dorsal spine' of the Meseta and divides it into northern and southern subregions. Rising to about 2,500 meters (8,200 feet), these mountains display some glacial features and are snow-capped for most of the year. Offering almost year-round winter sports, the mountains are also important to the climate of Madrid.Three visualization methods were combined to produce this image: shading and color coding of topographic height and radar image intensity. The shade image was derived by computing topographic slope in the northwest-southeast direction. North-facing slopes appear bright and south-facing slopes appear dark. Color coding is directly related to topographic height, with green at the lower elevations, rising through yellow and brown to white at the highest elevations. The shade image was combined with the radar intensity image in the flat areas.Elevation data used in this image was acquired by the SRTM aboard the Space Shuttle Endeavour, launched on Feb. 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. SRTM was designed to

  10. The Interplay between Inflammation and Fibrosis in Kidney Transplantation

    2014-01-01

    Full Text Available Serial surveillance renal allograft biopsies have shown that early subclinical inflammation constitutes a risk factor for the development of interstitial fibrosis. More recently, it has been observed that persistent inflammation is also associated with fibrosis progression and chronic humoral rejection, two histological conditions associated with poor allograft survival. Treatment of subclinical inflammation with steroid boluses prevents progression of fibrosis and preserves renal function in patients treated with a cyclosporine-based regimen. Subclinical inflammation has been reduced after the introduction of tacrolimus based regimens, and it has been shown that immunosuppressive schedules that are effective in preventing acute rejection and subclinical inflammation may prevent the progression of fibrosis and chronic humoral rejection. On the other hand, minimization protocols are associated with progression of fibrosis, and noncompliance with the immunosuppressive regime constitutes a major risk factor for chronic humoral rejection. Thus, adequate immunosuppressive treatment, avoiding minimization strategies and reinforcing educational actions to prevent noncompliance, is at present an effective approach to combat the progression of fibrosis.

    2016-06-01

    Full Text Available Renal fibrosis can be induced in different renal diseases, but ultimately progresses to end stage renal disease. Although the pathophysiologic process of renal fibrosis have not been fully elucidated, it is characterized by glomerulosclerosis and/or tubular interstitial fibrosis, and is believed to be caused by the proliferation of renal inherent cells, including glomerular epithelial cells, mesangial cells, and endothelial cells, along with defective kidney repair, renal interstitial fibroblasts activation, and extracellular matrix deposition. Receptor tyrosine kinases (RTKs regulate a variety of cell physiological processes, including metabolism, growth, differentiation, and survival. Many studies from in vitro and animal models have provided evidence that RTKs play important roles in the pathogenic process of renal fibrosis. It is also showed that tyrosine kinases inhibitors (TKIs have anti-fibrotic effects in basic research and clinical trials. In this review, we summarize the evidence for involvement of specific RTKs in renal fibrosis process and the employment of TKIs as a therapeutic approach for renal fibrosis.

    In this work, two different stochastic models will be considered, both oriented to the real-time forecast of daily SO 2 pollution in Madrid. The first one a ''black-box'' model, in which the input-output transfer function is identified by means of the methodology given by Box and Jenkins. The second one is a ''grey-box'' model with a simple reasonable structure in accordance with the physical laws of the phenomena. Moreover, its parameters can assume different values according to the different meteorological synoptic classes defined in part I. The comparison between the performance of the two models shows that the second one is more effective in predicting the critical pollution values

    Context Cystic fibrosis (CF) is the most widespread autosomal recessive genetic disorder that limits life expectation amongst the Caucasian population. As the median survival has increased related to early multidisciplinary intervention, other manifestations of CF have emergedespecially for the broad spectrum of hepatobiliary involvement. The present study reviews the existing literature on liver disease in cystic fibrosis and describes the key issues for an adequate clinical evaluation and management of patients, with a focus on the pathogenetic, clinical and diagnostic-therapeutic aspects of liver disease in CF. Evidence Acquisition A literature search of electronic databases was undertaken for relevant studies published from 1990 about liver disease in cystic fibrosis. The databases searched were: EMBASE, PubMed and Cochrane Library. Results CF is due to mutations in the gene on chromosome 7 that encodes an amino acidic polypeptide named CFTR (cystic fibrosis transmembrane regulator). The hepatic manifestations include particular changes referring to the basic CFTR defect, iatrogenic lesions or consequences of the multisystem disease. Even though hepatobiliary disease is the most common non-pulmonary cause ofmortalityin CF (the third after pulmonary disease and transplant complications), only about the 33%ofCF patients presents clinically significant hepatobiliary disease. Conclusions Liver disease will have a growing impact on survival and quality of life of cystic fibrosis patients because a longer life expectancy and for this it is important its early recognition and a correct clinical management aimed atdelaying the onset of complications. This review could represent an opportunity to encourage researchers to better investigate genotype-phenotype correlation associated with the development of cystic fibrosis liver disease, especially for non-CFTR genetic polymorphisms, and detect predisposed individuals.

    Full Text Available This paper studies the characteristics and recent evolution (1986-2001 of labourforce participation by gender in the region of Madrid, Spain. These characteristics can be related to the recent economic reestructuring process experienced by global capitalism and its productive, social and territorial consequences in our region. After a study of the sociodemographic dimensions of the labourmarket, a territorial perspective is adopted: we recognize, at a local level of detail, the different spatial patterns of male and female activity rates and their evolution. Finally, the analysis attemps to identify the effect of the spatial variation of certain municipal indicators on the distribution of the labourforce participation by gender along the Madrid Metropolitan Area and the entire region of Madrid.

    En este artículo se estudian las características y evolución de la participación laboral según género en la Comunidad de Madrid en el periodo 1986-2001 en el marco de los procesos de cambio social, productivo y territorial que han afectado a la región en los últimos años.

    2003-01-01

    Full Text Available Cystic fibrosis is a genetic disease usually diagnosed by abnormal sweat testing. We report a case of an 18-year-old female with bronchiectasis, chronic P. aeruginosa infection, and normal sweat chloride concentrations who experienced rapid decrease of lung function and clinical deterioration despite treatment. Given the high suspicion ofcystic fibrosis, broad genotyping testing was performed, showing a compound heterozygous with deltaF508 and 3849+10kb C->T mutations, therefore confirming cystic fibrosis diagnosis. Although the sweat chloride test remains the gold standard for the diagnosis of cystic fibrosis, alternative diagnostic tests such as genotyping and electrophysiologic measurements must be performed if there is suspicion of cystic fibrosis, despite normal or borderline sweat chloride levels.

  20. Reversal of liver fibrosis: From fiction to reality.

    Science.gov (United States)

    Zoubek, Miguel Eugenio; Trautwein, Christian; Strnad, Pavel

    2017-04-01

    In chronic liver diseases, an ongoing hepatocellular injury together with inflammatory reaction results in activation of hepatic stellate cells (HSCs) and increased deposition of extracellular matrix (ECM) termed as liver fibrosis. It can progress to cirrhosis that is characterized by parenchymal and vascular architectural changes together with the presence of regenerative nodules. Even at late stage, liver fibrosis is reversible and the underlying mechanisms include a switch in the inflammatory environment, elimination or regression of activated HSCs and degradation of ECM. While animal models have been indispensable for our understanding of liver fibrosis, they possess several important limitations and need to be further refined. A better insight into the liver fibrogenesis resulted in a large number of clinical trials aiming at reversing liver fibrosis, particularly in patients with non-alcoholic steatohepatitis. Collectively, the current developments demonstrate that reversal of liver fibrosis is turning from fiction to reality. Copyright © 2017. Published by Elsevier Ltd.

  3. Inhibition of the Unfolded Protein Response Mechanism Prevents Cardiac Fibrosis.

    Full Text Available Cardiac fibrosis attributed to excessive deposition of extracellular matrix proteins is a major cause of heart failure and death. Cardiac fibrosis is extremely difficult and challenging to treat in a clinical setting due to lack of understanding of molecular mechanisms leading to cardiac fibrosis and effective anti-fibrotic therapies. The objective in this study was to examine whether unfolded protein response (UPR pathway mediates cardiac fibrosis and whether a pharmacological intervention to modulate UPR can prevent cardiac fibrosis and preserve heart function.We demonstrate here that the mechanism leading to development of fibrosis in a mouse with increased expression of calreticulin, a model of heart failure, stems from impairment of endoplasmic reticulum (ER homeostasis, transient activation of the unfolded protein response (UPR pathway and stimulation of the TGFβ1/Smad2/3 signaling pathway. Remarkably, sustained pharmacologic inhibition of the UPR pathway by tauroursodeoxycholic acid (TUDCA is sufficient to prevent cardiac fibrosis, and improved exercise tolerance.We show that the mechanism leading to development of fibrosis in a mouse model of heart failure stems from transient activation of UPR pathway leading to persistent remodelling of cardiac tissue. Blocking the activation of the transiently activated UPR pathway by TUDCA prevented cardiac fibrosis, and improved prognosis. These findings offer a window for additional interventions that can preserve heart function.

    Previous studies have reported that caveolin-1 (Cav-1) is associated with lung fibrosis. However, the role of Cav-1 expression in pirfenidone-treated idiopathic pulmonary fibrosis (IPF) is unknown. This study investigated Cav-1 expression in pirfenidone-treated IPF, and compared the effects of pirfenidone with acetylcysteine and prednisone on IPF. Rat IPF model was established by endotracheal injection of 5 mg/kg bleomycin A5 into the specific pathogen-free Wistar male rats. Pirfenidone (P, 100 mg/kg once daily), prednisone (H, 5 mg/kg once daily) and acetylcysteine (N, 4 mg/kg 3 times per day) were used to treat the rat model by intragastric administration for 45 consecutive days, respectively. The normal rats without IPF were used as the controls. After 15, 30 and 45 days of drug treatment, lung histopathology was assessed. The expression of Cav-1 was determined using real-time quantitative PCR and Western blot; the expression of tumour necrosis factor-α (TNF-α), transforming growth factor-β1 (TGF-β1) and platelet-derived growth factor (PDGF) was determined by enzyme-linked immunosorbent assay. After 15, 30 and 45 days of drug treatment, comparison of the three drug-treated groups with the model group showed significantly lower (p fibrosis scores of lung tissues, as well as expression of TGF-β1, TNF-α and PDGF, but the expression of Cav-1 was higher (p fibrosis score was significantly lower and the protein expression of Cav-1 was significantly higher in the P group (p fibrosis scores (r = -0.506, p pulmonary fibrosis in rat IPF models, which may be related with enhanced caveolin-1, reduced TNF-α, TGF-β1, PDGF.

    In 1998, arsenic concentrations of more than 50 micrograms/l were detected in some drinking water supplies from underground sources in the Autonomous Community of Madrid, which is the maximum permissible concentration for drinking water in Spain. These two facts have meant the getting under way of a specific plan for monitoring arsenic in the drinking water in the Autonomous Community of Madrid. The results of the first two sampling processes conducted in the arsenic level monitoring plan set out are presented. In the initial phase, water samples from 353 water supplies comprised within the census of the Public Health Administration of the Autonomous Community of Madrid were analyzed. A water supply risk classification was made based on these initial results. In a second phase, six months later, the analyses were repeated on those 35 water supplies which were considered to possibly pose a risk to public health. Seventy-four percent (74%) of the water supplies studied in the initial phase were revealed to have an arsenic concentration of less than 10 micrograms/l, 22.6% containing levels of 10 micrograms/l-50 micrograms/l, and 3.7% over 50 micrograms/l. Most of the water supplies showing arsenic levels of more than 10 micrograms/l are located in the same geographical area. In the second sampling process (six months later), the 35 water supplies classified as posing a risk were included. Twenty-six (26) of these supplies were revealed to have the same arsenic level ((10-50 micrograms/l), and nine changed category, six of which had less than 10 micrograms/l and three more than 50 micrograms/l. In the Autonomous Community of Madrid, less than 2% of the population drinks water coming from supplies which are from underground sources. The regular water quality monitoring conducted by the Public Health Administration has led to detecting the presence of more than 50 micrograms/l of arsenic in sixteen drinking water supplies from underground sources, which is the maximum

    Full Text Available Prediction of liver fibrosis progression has a key role in the management of chronic viral hepatitis, as it will be translated into the future risk of cirrhosis and its various complications including hepatocellular carcinoma. Both hepatitis B and C viruses mainly lead to fibrogenesis induced by chronic inflammation and a continuous wound healing response. At the same time direct and indirect profibrogenic responses are also elicited by the viral infection. There are a handful of well-established risk factors for fibrosis progression including older age, male gender, alcohol use, high viral load and co-infection with other viruses. Metabolic syndrome is an evolving risk factor of fibrosis progression. The new notion of regression of advanced fibrosis or even cirrhosis is now strongly supported various clinical studies. Even liver biopsy retains its important role in the assessment of fibrosis progression, various non-invasive assessments have been adopted widely because of their non-invasiveness, which facilitates serial applications in large cohorts of subjects. Transient elastography is one of the most validated tools which has both diagnostic and prognostic role. As there is no single perfect test for liver fibrosis assessment, algorithms combining the most validated noninvasive methods should be considered as initial screening tools.

    To describe the nutritional content of products offered in food and drink vending machines at secondary schools in the Madrid Autonomous Community (Spain), and to evaluate these items' adherence to the nutritional recommendations of the National Health System Consensus Document on School Food. Cross-sectional study of a sample of 330 secondary schools in Madrid across the period 2014-2015. Secondary school vending machines were identified by telephone interview. The products offered in a representative sample of six machines were identified by inspection in situ, and their nutritional composition was obtained from the labelling. A total of 94.5% of the 55 products on offer failed to comply with at least one nutritional criterion of the Consensus Document on School Food. The recommendation relating to sugar content registered the highest level of non-compliance, with 52.7% of products, followed by the recommendations relating to energy (47.3%) and fats (45.5%). The mean number of unmet criteria was 2.2, with this figure being higher in foods than in drinks (2.8 versus 1; p <0.01). Almost all the products on display in secondary school vending machines in Madrid were in breach of the Consensus Document on School Food, mainly due to an excess of calories, sugars and fats. Compulsory nutritional criteria and a procedure for monitoring adherence should be established, specifying those responsible for performing this task and the corrective measures to be applied in the event of non-compliance.

    In this study, the hepatoprotective and anti-fibrotic actions of nootkatone (NTK) were investigated using carbon tetrachloride (CCl 4 )-induced liver fibrosis in mice. CCl 4 administration elevated serum aspartate and alanine transaminases levels, respectively. In addition, CCl 4 produced hepatic oxidative and nitrative stress, characterized by diminished hemeoxygenase-1 expression, antioxidant defenses, and accumulation of 4-hydroxynonenal and 3-nitrotyrosine. Furthermore, CCl 4 administration evoked profound expression of pro-inflammatory cytokine expressions such as tumor necrosis factor-α, monocyte chemoattractant protein-1, and interleukin-1β in hepatic tissues, which corroborated with nuclear factor κB activation. Additionally, CCl 4 -treated animals exhibited higher apoptosis, characterized by increased caspase 3 activity, DNA fragmentation, and poly (ADP-ribose) polymerase activation. Moreover, histological and biochemical investigations revealed marked fibrosis in the livers of CCl 4 -administered animals. However, NTK treatment mitigated CCl 4 -induced phenotypic changes. In conclusion, our findings suggest that NTK exerts hepatoprotective and anti-fibrotic actions by suppressing oxidative stress, inflammation, and apoptosis. © 2017 Wiley Periodicals, Inc.

    2015-04-01

    Understanding the molecular mechanisms underlying liver fibrogenesis is fundamentally relevant to developing new treatments that are independent of the underlying etiology. The increasing success of antiviral treatments in blocking or reversing the fibrogenic progression of chronic liver disease has unearthed vital information about the natural history of fibrosis regression, and has established important principles and targets for antifibrotic drugs. Although antifibrotic activity has been demonstrated for many compounds in vitro and in animal models, none has been thoroughly validated in the clinic or commercialized as a therapy for fibrosis. In addition, it is likely that combination therapies that affect two or more key pathogenic targets and/or pathways will be needed. To accelerate the preclinical development of these combination therapies, reliable single target validation is necessary, followed by the rational selection and systematic testing of combination approaches. Improved noninvasive tools for the assessment of fibrosis content, fibrogenesis and fibrolysis must accompany in vivo validation in experimental fibrosis models, and especially in clinical trials. The rapidly changing landscape of clinical trial design for liver disease is recognized by regulatory agencies in the United States (FDA) and Western Europe (EMA), who are working together with the broad range of stakeholders to standardize approaches to testing antifibrotic drugs in cohorts of patients with chronic liver diseases.

    Full Text Available In the downtown of Madrid there are currently 147 CCTV cameras controlled by the Municipal Police, forming an entire control mesh digitalized through which the look of power is imposed as a standard element in order to produce safety spaces. Far from being a declining reality, this is presented with increasing frequency as a "necessity", and thus, the mayor of Madrid, Ana Botella, has asked to the Government Delegation for installing 46 surveillance cameras more, in order to create "a large shopping and leisure environment covered with closed circuit television, an "ambitious security plan for shopping tourism". One of the central areas where they are concentrated is the neighborhood of Lavapies, where a total of 48 cameras to "fight crime and increase the sense of security" are installed. The discourses who try to legitimize the process of mass implementation of video surveillance in public space usually refer to "security reasons", and "improving the quality of life for residents and visitors". But ... what safety and quality of life are we talking about? Who and how are you protecting? Is it really an effective system of crime control? Try to answer these questions and allude to some resistance movements that have emerged against this process of implementation of urban electronic panopticon in order to question critically the discourses of safety is the objective of this article.

    PURPOSE OF REVIEW: The aim of this article is to outline the history of nephrogenic systemic fibrosis, a new and serious disease of patients with renal failure, and to give an update on its aetiology and prevalence. RECENT FINDINGS: Epidemiological and histochemical studies demonstrated....... Increasingly poor renal function, aberrations in calcium-phosphate metabolism and erythropoietin treatment seem to increase the risk of the disease and its severity. Up to 25-30% of patients with renal failure exposed to gadolinium-based contrast agents may develop nephrogenic systemic disease. The figure...... that gadolinium-containing contrast agents used for magnetic resonance imaging have an essential causative role in most, if not all, cases of nephrogenic systemic fibrosis. One particular agent, gadodiamide, caused the majority of cases, but gadopentetate dimeglumine has also been implicated in several cases...

    Regardless of their primary causes, progressive renal fibrosis and tubular atrophy are the main predictors of progression to end-stage renal disease. Basigin/CD147 is a multifunctional molecule-it induces matrix metalloproteinases and hyaluronan, for example-and has been implicated in organ fibrosis. However, the relationship between basigin and organ fibrosis has been poorly studied. We investigated basigin's role in renal fibrosis using a unilateral ureteral obstruction model. Basigin-deficient mice (Bsg(-/-)) demonstrated significantly less fibrosis after surgery than Bsg(+/+) mice. Fewer macrophages had infiltrated in Bsg(-/-) kidneys. Consistent with these in vivo data, primary cultured tubular epithelial cells from Bsg(-/-) mice produced less matrix metalloproteinase and exhibited less motility on stimulation with transforming growth factor β. Furthermore, Bsg(-/-) embryonic fibro blasts produced less hyaluronan and α-smooth muscle actin after transforming growth factor β stimulation. Together, these results demonstrate for the first time that basigin is a key regulator of renal fibrosis. Basigin could be a candidate target molecule for the prevention of organ fibrosis.

    The Guadarrama Monitoring Network initiative (GuMNet) is an observational infrastructure focused on monitoring the state of the atmosphere, surface and subsurface in the Sierra de Guadarrama, 50 km NW of the city of Madrid. The network is composed of 10 automatic real time weather stations ranging from low altitude (ca. 900 m.a.s.l) to high mountain areas (ca. 2400 m.a.s.l). The GuMNet infrastructure consists in 10 real time automatic weather stations with instrumentation for observing the state of the atmosphere, surface and the subsurface at the Sierra de Guadarrama, just 50 km north-northwest of the city of Madrid. GuMNet lays the foundations of a research network on weather, soil thermodynamics, boundary layer physics, climate and ecosystem oriented impacts, air pollutions, etc. in the Sierra de Guadarrama. GuMNet represents a first step to provide a unique observational network in an environment of high protection to be used as a laboratory serving a wide range of scientific and educational interests. High altitude sites are focused on periglacial areas and lower altitude sites have emphasis on pastures. One of the low altitude sites is equipped with a 10 m high anemometric tower with a 3D sonic anemometer at the top jointly with a CO2/H2O analyzer that will allow sampling of wind profiles and H2O and CO2 eddy covariance fluxes, important for soil respiration and CO2 and water vapor exchange. A portable station has also a 3D sonic anemometer with CO2/H2O analyzer, this 4 meters-high portable tower is designed for comparison with other soil terrain fluxes. The network is connected via general packet radio service (GPRS) to the central lab in the Campus of Excellence of Moncloa and a management software has been developed to handle the operation of the infrastructure. The deployment of instrumentation and connection of sites to the network was finished in 2016. GuMNet is currently in the process of becoming operational. Conceptually, GuMNet intends to convert a

    Full Text Available Pulmonary fibrosis is a progressive and fatal fibrotic disease of the lungs with unclear etiology. Recent insight has suggested that early injury/inflammation of alveolar epithelial cells could lead to dysregulation of tissue repair driven by multiple cytokines. Although dysregulation of interleukin- (IL- 22 is involved in various pulmonary pathophysiological processes, the role of IL-22 in fibrotic lung diseases is still unclear and needs to be further addressed. Here we investigated the effect of IL-22 on alveolar epithelial cells in the bleomycin- (BLM- induced pulmonary fibrosis. BLM-treated mice showed significantly decreased level of IL-22 in the lung. IL-22 produced γδT cells were also decreased significantly both in the tissues of lungs and spleens. Administration of recombinant human IL-22 to alveolar epithelial cell line A549 cells ameliorated epithelial to mesenchymal transition (EMT and partially reversed the impaired cell viability induced by BLM. Furthermore, blockage of IL-22 deteriorated pulmonary fibrosis, with elevated EMT marker (α-smooth muscle actin (α-SMA and overactivated Smad2. Our results indicate that IL-22 may play a protective role in the development of BLM-induced pulmonary fibrosis and may suggest IL-22 as a novel immunotherapy tool in treating pulmonary fibrosis.

    Full Text Available Cystic fibrosis (CF is the most common autosomal recessive disorder in Caucasian populations. Individuals with CF have seen significant increases in life expectancy in the last 60 years. As a result, previously rare complications are now coming to light. The most common of these is cystic fibrosis-related diabetes (CFRD, which affects 40–50% of CF adults. CFRD significantly impacts the pulmonary function and longevity of CF patients, yet a lack of consensus on the best methods to diagnose and treat CFRD remains. We begin by reviewing our understanding of the pathogenesis of CFRD, as emerging evidence shows the cystic fibrosis transmembrane conductance regulator (CFTR also has important roles in the release of insulin and glucagon and in the protection of β cells from oxidative stress. We then discuss how current recommended methods of CFRD diagnosis are not appropriate, as continuous glucose monitoring becomes more effective, practical, and cost-effective. Finally, we evaluate emerging treatments which have narrowed the mortality gap within the CF patient group. In the future, pharmacological potentiators and correctors directly targeting CFTR show huge promise for both CFRD and the wider CF patient groups.

    Immunoreactive trypsin (IRT) was measured in dried blood spots from 160.822 five-day-old babies as a part of a regionwide neonatal screening program for cystic fibrosis. A second test was performed for 492 babies in whom blood IRT levels were found greater than 900 μg/l; retesting revealed persistent elevation in 55. Sweat testing confirmed cystic fibrosis in 43 babies, but results were normal in 12. During the course of this study, a total of 51 cystic fibrosis babies were identified: 43 by newborn screening, 6 because they had meconium ileus; so, early diagnosis was achieved in 49 cases out of 51. Two newborn babies did not have elevated IRT and they were missed by the screening test. Our results confirm that elevated blood IRT is characteristic of newborn babies with cystic fibrosis and show that this test has an excellent specificity (99.7%) and a good sensitivity (95%) when used as a neonatal screening test [fr

  7. Molecular and cellular mechanisms of pulmonary fibrosis

    Science.gov (United States)

    2012-01-01

    Pulmonary fibrosis is a chronic lung disease characterized by excessive accumulation of extracellular matrix (ECM) and remodeling of the lung architecture. Idiopathic pulmonary fibrosis is considered the most common and severe form of the disease, with a median survival of approximately three years and no proven effective therapy. Despite the fact that effective treatments are absent and the precise mechanisms that drive fibrosis in most patients remain incompletely understood, an extensive body of scientific literature regarding pulmonary fibrosis has accumulated over the past 35 years. In this review, we discuss three broad areas which have been explored that may be responsible for the combination of altered lung fibroblasts, loss of alveolar epithelial cells, and excessive accumulation of ECM: inflammation and immune mechanisms, oxidative stress and oxidative signaling, and procoagulant mechanisms. We discuss each of these processes separately to facilitate clarity, but certainly significant interplay will occur amongst these pathways in patients with this disease. PMID:22824096

    Retroperitoneal fibrosis represents a rare inflammatory disease. About two thirds of all cases seem to be idiopathic (= Ormond's disease). The remaining one third is secondary and may be ascribed to infections, trauma, radiation therapy, malignant diseases, and the use of certain drugs. Up to 15 % of patients have additional fibrotic processes outside the retroperitoneum. The clinical symptoms of retroperitoneal fibrosis are non-specific. In sonography retroperitoneal fibrosis appears as a retroperitoneal hypoechoic mass which can involve the ureters and thus cause hydronephrosis. Intravenous urography and MR urography can demonstrate the typical triad of medial deviation and extrinsic compression of the ureters and hydronephrosis. CT and MRI are the modalities of choice for the diagnosis and follow-up of this disease. The lesion typically begins at the level of the fourth or fifth lumbar vertebra and appears as a plaque, encasing the aorta and the inferior vena cava and often enveloping and medially displacing the ureters. In unenhanced CT, retroperitoneal fibrosis appears as a mass that is isodense with muscle. When using MRI, the mass is hypointense in T1-weighted images and of variable intensity in T2-weighted images according to its stage: it may be hyperintense in early stages, while the tissue may have a low signal in late stages. After the administration of contrast media, enhancement is greatest in the early inflammatory phase and minimal in the late fibrotic phase. Dynamic gadolinium enhancement can be useful for assessing disease activity, monitoring response to treatment, and detecting relapse. To differentiate retroperitoneal masses, diffusion-weighted MRI may provide useful information. (orig.)

    The natural history of Crohn's disease follows a path of progression from an inflammatory to a fibrostenosing disease, with most patients requiring surgical resection of fibrotic strictures. Potent antiinflammatory therapies reduce inflammation but do not appear to alter the natural history of intestinal fibrosis. The aim of this study was to determine the relationship between intestinal inflammation and fibrogenesis and the impact of a very early "top-down" interventional approach on fibrosis in vivo. In this study we removed the inflammatory stimulus from the Salmonella typhimurium mouse model of intestinal fibrosis by eradicating the S. typhimurium infection with levofloxacin at sequential timepoints during the infection. We evaluated the effect of this elimination of the inflammatory stimulus on the natural history of inflammation and fibrosis as determined by gross pathology, histopathology, mRNA expression, and protein expression. Fibrogenesis is preceded by inflammation. Delayed eradication of the inflammatory stimulus by antibiotic treatment represses inflammation without preventing fibrosis. Early intervention significantly ameliorates but does not completely prevent subsequent fibrosis. This study demonstrates that intestinal fibrosis develops despite removal of an inflammatory stimulus and elimination of inflammation. Early intervention ameliorates but does not abolish subsequent fibrosis, suggesting that fibrosis, once initiated, is self-propagating, suggesting that a very early top-down interventional approach may have the most impact on fibrostenosing disease.

    Sexually transmitted diseases are a significant public health problem. Within the Madrid Autonomous Region, the districts with the highest syphilis and gonorrhea incidences are part of the same Public Health Service (Servicio de Salud Pública del Área 7, SSPA 7). The objective of this study was to identify, by spatial analysis, clusters of syphilis and gonorrhea infections in this SSPA in Madrid. All confirmed syphilis and gonorrhea cases registered in SSPA 7 in Madrid were selected. Moran's I was calculated in order to identify the existence of spatial autocorrelation and a cluster analysis was performed. Clusters and cumulative incidences (CI) per health zone were mapped. The district with most cases was Centro (CI: 67.5 and 160.7 per 100.000 inhabitants for syphilis and gonorrhea, respectively) with the highest CI (120.0 and 322.6 per 100.000 inhabitants) in the Justicia health zone.91.6% of all syphilis cases and 89.6% of gonorrhea cases were among men who have sex with men (MSM). Moran's I was 0.54 and 0.55 (p=0.001) for syphilis and gonorrhea, respectively. For syphilis, a cluster was identified including the six health zones of the Centro district, with a relative risk (RR)of 6.66 (p=0.001). For gonorrhea, a cluster was found including the Centro district, three health zones of the Chamberí district and one of Latina (RR 5.05; p=0.001). Centro was the district with most cases of syphilis and gonorrhea and the most affected population were MSM. For both infections, clusters were found with an important overlap. By identifying the most vulnerable health zones and populations, these results can help to design public health measures for preventing sexually transmitted diseases.

    Alcohol is the leading cause of cirrhosis and liver-related mortality, but we lack serum markers to detect compensated disease. We compared the accuracy of the Enhanced Liver Fibrosis test (ELF), the FibroTest, liver stiffness measurements (made by transient elastography and 2-dimensional shear-wave elastography), and 6 indirect marker tests in detection of advanced liver fibrosis (Kleiner stage ≥F3). We performed a prospective study of 10 liver fibrosis markers (patented and not), all performed on the same day. Patients were recruited from primary centers (municipal alcohol rehabilitation, n = 128; 6% with advanced fibrosis) and secondary health care centers (hospital outpatient clinics, n = 161; 36% with advanced fibrosis) in the Region of Southern Denmark from 2013 through 2016. Biopsy-verified fibrosis stage was used as the reference standard. The primary aim was to validate ELF in detection of advanced fibrosis in patients with alcoholic liver disease recruited from primary and secondary health care centers, using the literature-based cutoff value of 10.5. Secondary aims were to assess the diagnostic accuracy of ELF for significant fibrosis and cirrhosis and to determine whether combinations of fibrosis markers increase diagnostic yield. The ELF identified patients with advanced liver fibrosis with an area under the receiver operating characteristic curve (AUROC) of 0.92 (95% confidence interval 0.89-0.96); findings did not differ significantly between patients from primary vs secondary care (P = .917). ELF more accurately identified patients with advanced liver fibrosis than indirect marker tests, but ELF and FibroTest had comparable diagnostic accuracies (AUROC of FibroTest, 0.90) (P = .209 for comparison with ELF). Results from the ELF and FibroTest did not differ significantly from those of liver stiffness measurement in intention-to-diagnose analyses (AUROC for transient elastography, 0.90), but did differ in the per-protocol analysis (AUROC for

    Purpose: To extend knowledge on the mechanisms and pathways involved in maintenance of radiation-induced fibrosis (RIF) by performing gene expression profiling of whole blood from breast cancer (BC) survivors with and without fibrosis 3-7 years after end of radiotherapy treatment. Methods and Materials: Gene expression profiles from blood were obtained for 254 BC survivors derived from a cohort of survivors, treated with adjuvant radiotherapy for breast cancer 3-7 years earlier. Analyses of transcriptional differences in blood gene expression between BC survivors with fibrosis (n = 31) and BC survivors without fibrosis (n = 223) were performed using R version 2.8.0 and tools from the Bioconductor project. Gene sets extracted through a literature search on fibrosis and breast cancer were subsequently used in gene set enrichment analysis. Results: Substantial differences in blood gene expression between BC survivors with and without fibrosis were observed, and 87 differentially expressed genes were identified through linear analysis. Transforming growth factor-β1 signaling was identified as the most significant gene set, showing a down-regulation of most of the core genes, together with up-regulation of a transcriptional activator of the inhibitor of fibrinolysis, Plasminogen activator inhibitor 1 in the BC survivors with fibrosis. Conclusion: Transforming growth factor-β1 signaling was found down-regulated during the maintenance phase of fibrosis as opposed to the up-regulation reported during the early, initiating phase of fibrosis. Hence, once the fibrotic tissue has developed, the maintenance phase might rather involve a deregulation of fibrinolysis and altered degradation of extracellular matrix components.

    Purpose: Pulmonary fibrosis is a disorder of the lungs with limited treatment options. Matrix metalloproteinases (MMPs) constitute a family of proteases that degrade extracellular matrix with roles in fibrosis. Here we studied the role of MMP13 in a radiation-induced lung fibrosis model using a MMP13 knockout mouse. Methods and Materials: We investigated the role of MMP13 in lung fibrosis by investigating the effects of MMP13 deficiency in C57Bl/6 mice after 20-Gy thoracic irradiation (6-MV Linac). The morphologic results in histology were correlated with qualitative and quantitative results of volume computed tomography (VCT), magnetic resonance imaging (MRI), and clinical outcome. Results: We found that MMP13 deficient mice developed less pulmonary fibrosis than their wildtype counterparts, showed attenuated acute pulmonary inflammation (days after irradiation), and a reduction of inflammation during the later fibrogenic phase (5-6 months after irradiation). The reduced fibrosis in MMP13 deficient mice was evident in histology with reduced thickening of alveolar septi and reduced remodeling of the lung architecture in good correlation with reduced features of lung fibrosis in qualitative and quantitative VCT and MRI studies. The partial resistance of MMP13-deficient mice to fibrosis was associated with a tendency towards a prolonged mouse survival. Conclusions: Our data indicate that MMP13 has a role in the development of radiation-induced pulmonary fibrosis. Further, our findings suggest that MMP13 constitutes a potential drug target to attenuate radiation-induced lung fibrosis.

    2011-01-01

    Full Text Available Traditional approach to cystic fibrosis patients treatment doesn’t involve upper respiratory tract assessment, though abnormal changes — consequences of the cystic fibrosis transmembrane conductivity regulator gene mutation- do affect nasal and paranasal mucosa to the same extent. Approximately half of cystic fibrosis patients suffer from chronic rhinosinusitis and/or nasal polyposis that worsens the clinical course of already severe disease. Chronic hyperplasia in paranasal cavities can be quite extensive, recurrent and can lead to destruction of osseous walls of the cavity and of nasal septum. Thus increasing the amount of hospital admissions and and their duration. Low awareness of ENT-specialists working in polyclinics and in hospitals of ENT-pathology in cystic fibrosis patients leads to belated diagnostics, excessive manipulations, ineffective treatment, including surgery. All these lays grounds to implication of the early screening diagnostic program and development of proper treatment methods of ENT-complications of cystic fibrosis — therapeutic as well as surgical, with strict specification of indications and contraindications.

    Localized fibrosis of the lung is usually scar tissue while diffuse pulmonary fibrosis is more often a sign of active disease. Chronic infiltrative lung disease may be classified into four categories: idiopathic pneumonitis, collagen diseases, granulomatosis (sarcoidosis), and caused by known diseases (pneumoconiosis, hypersensitivity pneumonitis, drug-induced lung disease, radiation).

    Leola N Chow

    Full Text Available Modulation of chemokine CXCL12 and its receptor CXCR4 has been implicated in attenuation of bleomycin (BLM-induced pulmonary fibrosis and carbon tetrachloride (CCl4-induced hepatic injury. In pulmonary fibrosis, published reports suggest that collagen production in the injured lung is derived from fibrocytes recruited from the circulation in response to release of pulmonary CXCL12. Conversely, in hepatic fibrosis, resident hepatic stellate cells (HSC, the key cell type in progression of fibrosis, upregulate CXCR4 expression in response to activation. Further, CXCL12 induces HSC proliferation and subsequent production of collagen I. In the current study, we evaluated AMD070, an orally bioavailable inhibitor of CXCL12/CXCR4 in alleviating BLM-induced pulmonary and CCl4-induced hepatic fibrosis in mice. Similar to other CXCR4 antagonists, treatment with AMD070 significantly increased leukocyte mobilization. However, in these two models of fibrosis, AMD070 had a negligible impact on extracellular matrix deposition. Interestingly, our results indicated that CXCL12/CXCR4 signaling has a role in improving mortality associated with BLM induced pulmonary injury, likely through dampening an early inflammatory response and/or vascular leakage. Together, these findings indicate that the CXCL12-CXCR4 signaling axis is not an effective target for reducing fibrosis.

    Cystic fibrosis is a common genetic disorder characterized by a severe lung inflammation and fibrosis leading to the patient's death. Enhanced angiogenesis in cystic fibrosis (CF) tissue has been suggested, probably caused by the process of inflammation, as similarly described in asthma and chronic bronchitis. The present study demonstrates an intrinsic pro-angiogenic status of cystic fibrosis airway epithelial cells. Microarray experiments showed that CF airway epithelial cells expressed several angiogenic factors such as VEGF-A, VEGF-C, bFGF, and PLGF at higher levels than control cells. These data were confirmed by real-time quantitative PCR and, at the protein level, by ELISA. Conditioned media of these cystic fibrosis cells were able to induce proliferation, migration and sprouting of cultured primary endothelial cells. This report describes for the first time that cystic fibrosis epithelial cells have an intrinsic angiogenic activity. Since excess of angiogenesis is correlated with more severe pulmonary disease, our results could lead to the development of new therapeutic applications

    The assessment of liver fibrosis in chronic hepatitis C patients is important for prognosis and making decisions regarding antiviral treatment. Although liver biopsy is considered the reference standard for assessing hepatic fibrosis in patients with chronic hepatitis C, it is invasive and associated with sampling and interobserver variability. Serum fibrosis markers have been utilized as surrogates for a liver biopsy. We completed a prospective study of 191 patients in which blood draws and liver biopsies were performed on the same visit. Using liver biopsies the sensitivity, specificity, and negative and positive predictive values for both aspartate aminotransferase/platelet ratio index (APRI) and enhanced liver fibrosis (ELF) were determined. The patients were divided into training and validation patient sets to develop and validate a clinically useful algorithm for differentiating mild and significant fibrosis. The area under the ROC curve for the APRI and ELF tests for the training set was 0.865 and 0.880, respectively. The clinical sensitivity in separating mild (F0-F1) from significant fibrosis (F2-F4) was 80% and 86.0% with a clinical specificity of 86.7% and 77.8%, respectively. For the validation sets the area under the ROC curve for the APRI and ELF tests was, 0.855 and 0.780, respectively. The clinical sensitivity of the APRI and ELF tests in separating mild (F0-F1) from significant (F2-F4) fibrosis for the validation set was 90.0% and 70.0% with a clinical specificity of 73.3% and 86.7%, respectively. There were no differences between the APRI and ELF tests in distinguishing mild from significant fibrosis for either the training or validation sets (P=0.61 and 0.20, respectively). Using APRI as the primary test followed by ELF for patients in the intermediate zone, would have decreased the number of liver biopsies needed by 40% for the validation set. Overall, use of our algorithm would have decreased the number of patients who needed a liver biopsy

  10. Therapy of experimental NASH and fibrosis with galectin inhibitors.

    Directory of Open Access Journals (Sweden)

    Peter G Traber

    Full Text Available Non-alcoholic steatohepatitis (NASH and resultant liver fibrosis is a major health problem without effective therapy. Some data suggest that galectin-3 null mice are resistant to the development of NASH with fibrosis. We examined the ability of two complex carbohydrate drugs that bind galectin-3, GM-CT-01 and GR-MD-02, to treat NASH with fibrosis in a murine model. GR-MD-02 treatment resulted in marked improvement in liver histology with significant reduction in NASH activity and collagen deposition. Treatments seemed also to improve both glomerulopathy and interstitial fibrosis observed in kidneys. The improvement in liver histology was evident when animals were treated early in disease or after establishment of liver fibrosis. In all measures, GM-CT-01 had an intermediate effect between vehicle and GR-MD-02. Galectin-3 protein expression was increased in NASH with highest expression in macrophages surrounding lipid laden hepatocytes, and reduced following treatment with GR-MD-02, while the number of macrophages was unchanged. Treatment with GR-MD-02 also reduced the expression of pathological indicators including iNOS, an important TH1 inflammatory mediator, CD36, a scavenger receptor for lipoproteins on macrophages, and α-smooth muscle actin, a marker for activated stellate cells which are the primary collagen producing cells in liver fibrosis. We conclude that treatment with these galectin-3 targeting drugs improved histopathological findings of NASH and markedly reduced fibrosis in a murine model of NASH. While the mechanisms require further investigation, the treatment effect is associated with a reduction of galectin-3 expressed by activated macrophages which was associated with regression of NASH, including hepatocellular fat accumulation, hepatocyte ballooning, intra-portal and intra-lobular inflammatory infiltrate, and deposition of collagen. Similar effects were found with GM-CT-01, but with approximately four-fold lower potency than

    Liver fibrosis refers to a reversible wound healing process response to chronic liver injuries. Activation of hepatic stellate cells (HSCs) is closely correlated with the development of liver fibrosis. Histone deacetylases(HDACs) determine the acetylation levels of core histones to modulate expression of genes. To demonstrate the link between HDACs and liver fibrosis, CCl4-induced mouse liver fibrosis model and its spontaneous reversal model were established. Results of the current study demonstrated that deregulation of liver HDACs may involved in the development of liver fibrosis. Among 11 HDACs tested in our study (Class I, II, and IV HDACs), expression of HDAC2 was maximally increased in CCl4-induced fibrotic livers but decreased after spontaneous recovery. Moreover, expression of HDAC2 was elevated in human liver fibrotic tissues. In this regard, the potential role of HDAC2 in liver fibrosis was further evaluated. Our results showed that administration of HSC-T6 cells with transforming growth factor-beta1 (TGF-β1) resulted in an increase of HDAC2 protein expression in dose- and time-dependent manners. Moreover, HDAC2 deficiency inhibited HSC-T6 cell proliferation and activation induced by TGF-β1. More importantly, the present study showed HDAC2 may regulate HSCs activation by suppressing expression of Smad7, which is a negative modulator in HSCs activation and liver fibrosis. Collectively, these observations revealed that HDAC2 may play a pivotal role in HSCs activation and liver fibrosis while deregulation of HDACs may serve as a novel mechanism underlying liver fibrosis. - Highlights: • This is the first report to systematically examine expressions of HDACs during liver fibrosis and fibrosis reversal. • Aberrant expression of HDAC2 contributes to the development of liver fibrosis. • Provided important foundation for further liver fibrosis conversion studies.

    Objectives: Patients with idiopathic pulmonary fibrosis (IPF) have an increased risk of pulmonary tuberculosis. However, detecting pulmonary tuberculosis may be difficult due to the underlying fibrosis. The aim of this report is to describe the radiological and clinical findings of pulmonary tuberculosis in patients with idiopathic pulmonary fibrosis. Materials and methods: We reviewed 143 consecutive patients in whom IPF was diagnosed by either the histological or radio-clinical criteria. Among them, nine patients were histologically (n=2) or bacteriologically (n=7) confirmed to have active pulmonary tuberculosis. The location and patterns of pulmonary tuberculosis were examined on a thin section CT scan. Results: The most common thin section CT findings were subpleural nodules (n=6; mean diameter, 3.2 cm) and a lobar or segmental consolidation (n=3). The lesions were located most commonly in the right lower lobe (n=4). The incidence of tuberculosis in patients with idiopathic pulmonary fibrosis was more than five times higher than that of the general population. Conclusion: The atypical manifestation of pulmonary tuberculosis is common in patients with idiopathic pulmonary fibrosis, which may mimic lung cancer or bacterial pneumonia.

    Over the last decade, great enthusiasm has evolved for microRNA (miRNA) therapeutics. Part of the excitement stems from the fact that a miRNA often regulates numerous related mRNAs. As such, modulation of a single miRNA allows for parallel regulation of multiple genes involved in a particular disease. While many studies have shown therapeutic efficacy using miRNA inhibitors, efforts to restore or increase the function of a miRNA have been lagging behind. The miR-29 family has gained a lot of attention for its clear function in tissue fibrosis. This fibroblast-enriched miRNA family is downregulated in fibrotic diseases which induces a coordinate increase of many extracellular matrix genes. Here, we show that intravenous injection of synthetic RNA duplexes can increase miR-29 levels in vivo for several days. Moreover, therapeutic delivery of these miR-29 mimics during bleomycin-induced pulmonary fibrosis restores endogenous miR-29 function whereby decreasing collagen expression and blocking and reversing pulmonary fibrosis. Our data support the feasibility of using miRNA mimics to therapeutically increase miRNAs and indicate miR-29 to be a potent therapeutic miRNA for treating pulmonary fibrosis. PMID:25239947

    Full text of publication follows: Purpose.-The aim of the study was to evaluate radioprotective effect of rosiglitazone (RGZ) on a murine model of late pulmonary damage and of acute intestinal damage. Methods.- Lung fibrosis: C57 mice were treated with the radiomimetic agent bleomycin, with or without rosiglitazone (5 mg/kg/day). To obtain an independent qualitative and quantitative measure for lung fibrosis we used high resolution CT, performed twice a week during the entire observation period. Hounsfield Units (HU) of section slides from the upper and lower lung region were determined. On day 31 lungs were collected for histological analysis. Acute intestinal damage: mice underwent 12 Gy total body irradiation with or without rosiglitazone. Mice were sacrificed 24 or 72 h after total body irradiation and ileum and colon were collected. Results.- Lung fibrosis: after bleomycin treatment, mice showed typical CT features of lung fibrosis, including irregular septal thickening and patchy peripheral reticular abnormalities. Accordingly, HU lung density was dramatically increased. Rosiglitazone markedly attenuated the radiological signs of fibrosis and strongly inhibited HU lung density increase (60% inhibition at the end of the observation period). Histological analysis revealed that in bleomycin-treated mice, fibrosis involved 50-55% of pulmonary parenchyma and caused an alteration of the alveolar structures in 10% of parenchyma, while in rosiglitazone-treated mice, fibrosis involved only 20-25% of pulmonary parenchyma, without alterations of the alveolar structures. Acute intestinal damage: 24 h after 12 Gy of total body irradiation intestinal mucosa showed villi shortening, mucosal thickness and crypt necrotic changes. Rosiglitazone showed a histological improvement of tissue structure, with villi and crypts normalization and oedema reduction. Conclusion.- These results demonstrate that rosiglitazone displays a protective effect on pulmonary fibrosis and radiation

    Various studies have reported that the photochemical nucleation of new ultrafine particles (UFPs) in urban environments within high insolation regions occurs simultaneously with high ground ozone (O3) levels. In this work, we evaluate the atmospheric dynamics leading to summer O3 episodes in the Madrid air basin (central Iberia) by means of measuring a 3-D distribution of concentrations for both pollutants. To this end, we obtained vertical profiles (up to 1200 m above ground level) using tethered balloons and miniaturised instrumentation at a suburban site located to the SW of the Madrid Metropolitan Area (MMA), the Majadahonda site (MJDH), in July 2016. Simultaneously, measurements of an extensive number of air quality and meteorological parameters were carried out at three supersites across the MMA. Furthermore, data from O3 soundings and daily radio soundings were also used to interpret atmospheric dynamics.The results demonstrate the concatenation of venting and accumulation episodes, with relative lows (venting) and peaks (accumulation) in O3 surface levels. Regardless of the episode type, the fumigation of high-altitude O3 (arising from a variety of origins) contributes the major proportion of surface O3 concentrations. Accumulation episodes are characterised by a relatively thinner planetary boundary layer ( 2400 m a.s.l.). This orographic-meteorological setting causes the vertical recirculation of air masses and enrichment of O3 in the lower tropospheric layers. When the highly polluted urban plume from Madrid is affected by these dynamics, the highest Ox (O3+ NO2) concentrations are recorded in the MMA.Vertical O3 profiles during venting episodes, with strong synoptic winds and a deepening of the planetary boundary layer reaching > 2000 m a.s.l., were characterised by an upward gradient in O3 levels, whereas a reverse situation with O3 concentration maxima at lower levels was found during the accumulation episodes due to local and/or regional production

    Policies restricting access to sugary drinks and unhealthy foods in the school environment are associated with healthier consumption patterns. In 2010, Spain approved a Consensus Document regarding Food at Schools with nutritional criteria to improve the nutritional profile of foods and drinks served at schools. The objective of this study was to describe the frequency of food and drink vending machines at secondary schools in Madrid, the products offered at them and their nutritional profile. Cross-sectional study of a random sample of 330 secondary schools in Madrid in 2014-2015. The characteristics of the schools and the existence of vending machines were recorded through the internet and by telephone interview. The products offered in a representative sample of 6 vending machines were identified by in situ inspection, and its nutritional composition was taken from its labeling. Finally, the nutritional profile of each product was analyzed with the United Kingdom profile model, which classifies products as healthy and less healthy. The prevalence of vending machines was 17.3%. Among the products offered, 80.5% were less healthy food and drinks (high in energy, fat or sugar and poor in nutrients) and 10.5% were healthy products. Vending machines are common at secondary schools in Madrid. Most products are vending machines are still less healthy.

    Production site development and alterations of early pulmonary fibrosis were studied. Single irradiation was made at right thorax of rats with 0, 15 and 30 Gy of γ-irradiation, respectively. The rats were divided into three groups which were sacrificed 1, 3, 5 months post irradiation. Hydroxyproline in lungs was measured by biochemical method. Pulmonary type I and III collagens were measured by polarization method. Distribution of angiotensin II (A II) in pulmonary tissues was displayed by immunohistochemical method. Extent of pulmonary fibrosis relatively increased with irradiation dose and time elapse after irradiation. Ratio of type I to type III collagens increased with increasing fibrosis. Proliferating collagen fibers mainly came from fibroblasts of pulmonary bronchial and arterial adventitia, and extended into pulmonary parenchyma. Meanwhile, type I collagen substituted for type III collagen in interstitium of pulmonary alveoli. A II was positive for fibroblasts and macrophages in pulmonary interstitium. Irradiation can stimulate fibroblasts in interstitium proliferation, and type I collagen substitutes for type III collagen. Expression and synthesis of A II in interstitium may promote the course of pulmonary fibrosis

    The 29th International Conference on Photonic, Electronic and Atomic Collisions (XXIX ICPEAC) was held at the Palacio de Congresos ''El Greco'', Toledo, Spain, on 22-28 July, 2015, and was organized by the Universidad Autónoma de Madrid (UAM) and the Consejo Superior de Investigaciones Científicas (CSIC). ICPEAC is held biannually and is one of the most important international conferences on atomic and molecular physics. The topic of the conference covers the recent progresses in photonic, electronic, and atomic collisions with matter. With a history back to 1958, ICPEAC came to Spain in 2015 for the very first time. UAM and CSIC had been preparing the conference for six years, ever since the ICPEAC International General Committee made the decision to hold the XXIX ICPEAC in Toledo. The conference gathered 670 participants from 52 countries and attracted 854 contributed papers for presentation in poster sessions. Among the latter, 754 are presented in issues 2-12 of this volume of the Journal of Physics Conference Series. In addition, five plenary lectures, including the opening one by the Nobel laureate Prof. Ahmed H. Zewail and the lectures by Prof. Maciej Lewenstein, Prof. Paul Scheier, Prof. Philip H. Bucksbaum, and Prof. Stephen J. Buckman, 62 progress reports and 26 special reports were presented following the decision of the ICPEAC International General Committee. Detailed write-ups of most of the latter are presented in issue 1 of this volume, constituting a comprehensive tangible record of the meeting. On the occasion of the International Year of Light (IYL2015) and with the support of the Fundación Española para la Ciencia y la Tecnología (FECYT), the program was completed with two public lectures delivered by the Nobel laureate Prof. Serge Haroche and the Príncipe de Asturias laureate Prof. Pedro M. Echenique on, respectively, ''Fifty years of laser revolutions in physics'rquot; and ''The sublime usefulness of useless science''. Also a

    Pulmonary fibrosis and emphysema are chronic lung diseases characterized by a progressive decline in lung function, resulting in significant morbidity and mortality. A hallmark of these diseases is recurrent or persistent alveolar epithelial injury, typically caused by common environmental exposures such as cigarette smoke. We propose that critical determinants of the outcome of the injury-repair processes that result in fibrosis versus emphysema are mesenchymal cell fate and associated extracellular matrix dynamics. In this review, we explore the concept that regulation of mesenchymal cells under the influence of soluble factors, in particular transforming growth factor-β1, and the extracellular matrix determine the divergent tissue remodeling responses seen in pulmonary fibrosis and emphysema.

    The Public Health General Directorate of Madrid has developed a health vulnerability mapping methodology to assist regional social health teams in health planning, prioritisation and intervention based on a model of social determinants of health and an equity approach. This process began with the selection of areas with the worst social indicators in health vulnerability. Then, key stakeholders of the region jointly identified priority areas of intervention and developed a consensual plan of action. We present the outcomes of this experience and its connection with theoretical models of asset-based community development, health-integrated georeferencing systems and community health interventions.

    The purpose of the study was to examine whether an interaction between two agents causing alveolar epithelial damage would produce lung fibrosis. In mouse lung, intraperitoneal injection of the antioxidant butylated hydroxytoluene causes diffuse alveolar type I cell necrosis, followed by proliferation of type II alveolar cells. In animals exposed to 70% O 2 or 100-200 rad x rays during the phase of type II cell proliferation following BHT, diffuse interstitial lung fibrosis developed within 2 weeks. Quantitative analysis of the lungs for hydroxyproline showed that the interaction between BHT and O 2 or x rays was synergistic. If exposure to O 2 or x rays was delayed until epithelial recovery was complete, no fibrosis was seen. Abnormally high levels of lung collagen persisted up to 6 months after one single treatment with BHT and 100 rad x rays. A commonly seen form of chronic lung damage may thus be caused by an acute interaction between a bloodborne agent which damages the alveolar cell and a toxic inhalant or x rays, provided a critically ordered sequence of exposure is observed

    Radiation fibrosis is the cardinal symptom of the chronicle stage of the cutaneous radiation syndrome. The degree of cutaneous fibrosis can clinically be estimated by palpation. High-frequency 20 MHz-sonography is an established, noninvasive procedure, which renders an exact determination of skin thickness and additionally densitometry is possible. We investigated 15 survivors of the Chernobyl accident in 1986, who developed symptoms of the chronic stage of the cutaneous radiation syndrome. We determined skin thickness and echogenicity of skin areas clinically suggestive of radiation fibrosis before, during and after treatment. 20 MHz-sonography showed a distinct enlargement of the echorich corium and a reduction of the subcutaneous fatty tissue in comparison with the unaffected, contralateral skin, here demonstrating typical features of radiation fibrosis, namely dermal fibrosis and reactive pseudoatrophy and fatty tissue. The histology presented an increase and swelling of the collagen fibers and atypical fibroblastic cells. The patients received treatment with low-dose interferon y (Polyfcron R , 3 x 50μg s.C., three times per week) up to 30 months. A marked reduction of skin thickness and echogenicity reaching nearly normal values could be observed. We conclude that 20 MHz-sonography is an easy to apply, noninvasive, well established procedure to quantify cutaneous radiation fibrosis and to assess therapeutic outcome

    Nonalcoholic fatty liver disease (NAFLD) is a common cause of chronic liver disease. We investigated factors associated with advanced fibrosis in NAFLD. The study included 432 patients with histologically proven NAFLD (26.8% with nonalcoholic steatohepatitis [NASH] and 17.4% with moderate-to severe fibrosis). NASH was defined as steatosis, lobular inflammation, and ballooning degeneration with or without Mallory-Denk bodies and/or fibrosis. Fibrosis was classified into 2 groups: those with no or minimal fibrosis and those with moderate-to-severe fibrosis. Groups were compared using Mann-Whitney and chi-square method analyses. A model was constructed using a stepwise bidirectional method; its predictive power was measured using a 10-fold cross-validation technique. Patients with NASH were more likely to be male (P < .0001); have lower hip-to-waist ratios (P = .03); were less likely to be African American (P = .06); have higher levels of alanine aminotransferase (ALT; P < .0001), aspartate aminotransferase (AST; P < .0001), and serum triglycerides (P = .0154), but lower levels of high-density lipoprotein cholesterol (P < .0001). Patients with moderate-to-severe fibrosis were older (P = .0245); more likely to be male (P = .0189), Caucasian (P = .0382), have diabetes mellitus (P = .0238), and hypertension (P = .0375); and have a lower hip-to-waist ratio (P = .0077) but higher serum AST (P < .0001) and ALT (P < .0001) levels. The multivariate analysis model to predict moderate-to-severe fibrosis included male sex, Caucasian ethnicity, diabetes mellitus, and increased AST and ALT levels (model P value < .0001). In patients with NAFLD, diabetes mellitus and aminotransferase levels are independent predictors of moderate-to-severe fibrosis. They can be used to identify NAFLD patients at risk for advanced fibrosis.

    A study on daily concentration changes of polycyclic aromatic and aliphatic hydrocarbons (PAH's and AH's), was carried out in aerosols sampled m the Ciudad Universitaria of Madrid. Samples were taken at morning and night during February and June, for short sampling times, on glass fiber filters in Hi-Vol samplers, and then extracted ultrasonically with cyclohexane. Analysis were performed by HRGC with fused-silica capillary columns. The variable traffic rate, and the strong influence during winter periods of domestic heating are characteristic of this place. The aim of this work was to evaluate diurnal and seasonal variations of selected AH and PAH in the urban area of Madrid, by using descriptive parameters, such as total concentrations of AH and PAH, characteristic profiles and predominance carbon index.

    To determine the accuracy of ultrasound in the diagnosis and grading of steatosis and fibrosis in Hepatitis C (HCV) patients not responding to ribavarin-interferon therapy. Study Design: A cross-sectional, analytical study. Place and Duration of Study: Radiology Department, Civil Hospital, Karachi, from March 2008 to August 2010. Methodology: Patients with positive HCV RNA despite 24 weeks ribavarin-interferon therapy (non-responders) were subjected to ultrasound and biopsy prior to institution of pegylated interferon therapy for detection and grading of steatosis and fibrosis. Using histopathology as the gold standard, sensitivity, specificity, negative and positive predictive values for ultrasound were determined. Results: The sensitivity of ultrasound for hepatic steatosis was 90.9% for no steatosis (NS), 100% for moderate and gross steatosis and 84.4% for mild steatosis with 100% specificity. The senitivity for fibrosis was 25% for no fibrosis, 100% for mild fibrosis, 89.74% for moderate fibrosis and 100% for gross fibrosis. The overall accuracy for detection of steatosis was 95.39% and that for fibrosis was 98.02%. Hepatic vein showed increased dampening of flow with advancing grades of steatosis and fibrosis. Conclusion: Ultrasound has a high accuracy in the diagnosis and grading of steatosis and fibrosis in HCV nonresponders. Mild fibrosis may confound the diagnosis of mild steatosis. (author)

    Full Text Available Gene therapy is an alternative treatment for genetic lung disease, especially monogenic disorders such as cystic fibrosis. Cystic fibrosis is a severe autosomal recessive disease affecting one in 2500 live births in the white population, caused by mutation of the cystic fibrosis transmembrane conductance regulator (CFTR. The disease is classically characterized by pancreatic enzyme insufficiency, an increased concentration of chloride in sweat, and varying severity of chronic obstructive lung disease. Currently, the greatest challenge for gene therapy is finding an ideal vector to deliver the transgene (CFTR to the affected organ (lung. Adeno-associated virus is the most promising viral vector system for the treatment of respiratory disease because it has natural tropism for airway epithelial cells and does not cause any human disease. This review focuses on the basic properties of adeno-associated virus and its use as a vector for cystic fibrosis gene therapy.

    Chronic loss of appetite in cystic fibrosis concerns both individuals and families. Appetite stimulants have been used to help cystic fibrosis patients with chronic anorexia attain optimal body mass index and nutritional status. However, these may have adverse effects on clinical status. The aim of this review is to systematically search for and evaluate evidence on the beneficial effects of appetite stimulants in the management of CF-related anorexia and synthesize reports of any side-effects. Trials were identified by searching the Cochrane Cystic Fibrosis and Genetic Disorders Group's Cystic Fibrosis Trials Register, MEDLINE, Embase, CINAHL, handsearching reference lists and contacting local and international experts.Last search of online databases: 01 April 2014.Last search of the Cystic Fibrosis Trials Register: 08 April 2014. Randomised and quasi-randomised controlled trials of appetite stimulants, compared to placebo or no treatment for at least one month in adults and children with cystic fibrosis. Authors independently extracted data and assessed the risk of bias within eligible trials. Meta-analyses were performed. Three trials (total of 47 recruited patients) comparing appetite stimulants (cyproheptadine hydrochloride and megesterol acetate) to placebo were included; the numbers of adults or children within each trial were not always reported. The risk of bias of the included trials was graded as moderate.A meta-analysis of all three trials showed appetite stimulants produced a larger increase in weight z score at three months compared to placebo, mean difference 0.61 (95% confidence interval 0.29 to 0.93) (P children, appetite stimulants improved only two of the outcomes in this review - weight (or weight z score) and appetite; and side effects were insufficiently reported to determine the full extent of their impact. Whilst the data may suggest the potential use of appetite stimulants in treating anorexia in adults and children with cystic fibrosis

  18. Comparing the New Madrid Seismic Zone with the Osning Thrust: implications for GIA-induced intraplate tectonics in northern Germany

    Continental intraplate tectonics is a widespread phenomenon that causes significant earthquakes. These earthquakes even occur in areas that are characterized by low strain rates and there are often long intervals between the individual seismic events (Gangopadhyay & Talwani, 2003) that result in a hazard potential. To better understand the controlling factors of intraplate plate earthquakes in northern Germany, we compare the Osning Thrust with the intensively-studied New Madrid Seismic Zone in the Midwest USA. Both areas share major similarities such as a failed rift-basin setting, the presence of intrusive magmatic bodies in the subsurface, tectonic reactivation during the Late Cretaceous, paleo- and historic seismicity and comparable fault parameters. In addition, both areas have a very similar Late Pleistocene deglaciation history. New Madrid was c. 340 km south of the Laurentide ice sheet and ice retreat started around 21 ka and was completed by 8.5 ka (Grollimund & Zoback, 2001). The Osning Thrust was c. 310 km south of the Scandinavian ice sheet and deglaciation began at 24 ka. Both areas show historic seismicity in a similar time frame (New Madrid Seismic Zone: 1811-1812, Johnston & Schweig, 1996); Osning Thrust: 1612 and 1767, Grünthal & Bosse, 1997). We use numerical simulations to identify the timing of potentially GIA-induced fault activity, which are based on the fault stability margin concept of Wu & Hasegawa (1996). From our modelling results it is evident that the fault stability margin changed to negative between 16 and 13 ka for the Osning Thrust, which matches the OSL data of fault-related growth strata (Brandes et al., 2012). For the New Madrid Seismic Zone, the fault stability margin becomes zero between 2.5 ka BP (before 1812) to about 2 ka after the 1812 event, depending on the parameters of the model. This indicates that for both seismic zones, seismicity due to deglaciation was and still is very likely. From this study it can be derived

    Full Text Available BACKGROUND: Cystic fibrosis-related liver disease (CFLD is present in up to 30% of cystic fibrosis patients and can result in progressive liver failure. Diagnosis of CFLD is challenging. Non-invasive methods for staging of liver fibrosis display an interesting diagnostic approach for CFLD detection. AIM: We evaluated transient elastography (TE, acoustic radiation force impulse imaging (ARFI, and fibrosis indices for CFLD detection. METHODS: TE and ARFI were performed in 55 adult CF patients. In addition, AST/Platelets-Ratio-Index (APRI, and Forns' score were calculated. Healthy probands and patients with alcoholic liver cirrhosis served as controls. RESULTS: Fourteen CF patients met CFLD criteria, six had liver cirrhosis. Elastography acquisition was successful in >89% of cases. Non-cirrhotic CFLD individuals showed elastography values similar to CF patients without liver involvement. Cases with liver cirrhosis differed significantly from other CFLD patients (ARFI: 1.49 vs. 1.13 m/s; p = 0.031; TE: 7.95 vs. 4.16 kPa; p = 0.020 and had significantly lower results than individuals with alcoholic liver cirrhosis (ARFI: 1.49 vs. 2.99 m/s; p = 0.002. APRI showed the best diagnostic performance for CFLD detection (AUROC 0.815; sensitivity 85.7%, specificity 70.7%. CONCLUSIONS: ARFI, TE, and laboratory based fibrosis indices correlate with each other and reliably detect CFLD related liver cirrhosis in adult CF patients. CF specific cut-off values for cirrhosis in adults are lower than in alcoholic cirrhosis.

    Evaluation of liver fibrosis stage is crucial in the assessment of chronic HCV patients, regarding decision to start treatment and during follow-up. Our aim was to assess the validity of the enhanced liver fibrosis (ELF) score in discrimination of advanced stage of liver fibrosis in naïve chronic HCV patients. We prospectively evaluated liver fibrosis stage in one hundred eighty-one naïve chronic HCV Egyptian patients by transient elastography (TE)-FibroScan. Patients were categorized into mild to moderate fibrosis (≤F2) group and advanced fibrosis (≥F3) group. The ELF score components, hyaluronic acid (HA), amino-terminal propeptide of type-III-procollagen (PIIINP) and tissue inhibitor of metalloproteinase type-1 (TIMP-1), were done using ELISA test. The mean values of ELF and its individual components significantly correlated with the hepatic fibrosis stage as measured by TE-FibroScan (P value 0.001). ELF cutoff value of 9.8 generated a sensitivity of 77.8%, specificity of 67.1%, area under the receiver operator characteristic curve (AUROC) of 0.76 with 95% confidence interval [CI] (0.68-0.83) for detecting advanced fibrosis (F ≥ 3). ELF panel is a good, reliable noninvasive test and showed comparable results to TE-FibroScan in detecting liver fibrosis stage in treatment naïve chronic HCV patients.

    Lung cancer is usually presented with cough, dyspnea, pain and weight loss, which is overlapping with symptoms of other lung diseases such as pulmonary fibrosis. Pulmonary fibrosis shows characteristic reticular and nodular pattern, while lung cancers are mostly presented with infiltrative mass, thick-walled cavitations or a solitary nodule with spiculated borders. If the diagnosis is established based on clinical symptoms and CT findings, it would be a misapprehension. We report a case of lung adenocarcinoma whose symptoms as well as clinical images overlapped strongly with pulmonary fibrosis. The patient’s non-productive cough, progressive dyspnea, restrictive pattern of pulmonary function test and CT scans (showing reticular interstitial opacities) were all indicative of pulmonary fibrosis. The patient underwent a treatment consisting of corticosteroids and antibiotics, to no avail. Histopathology of the lung showed that the patient suffered from mucinous adenocarcinoma. Albeit the immunohistochemical staining was not consistent with lung adenocarcinoma, tumor’s morphological characteristics were consistent, and were used to make the definitive diagnosis. Given the fact that radiography cannot always make a clear-cut difference between pulmonary fibrosis and lung adenocarcinomas, and that clinical symptoms often overlap, histological examination should be considered as gold standard for diagnosis of lung adenocarcinoma

    The progression of nonalcoholic fatty liver disease (NAFLD) has been linked to deregulated exchange of the endocrine signaling between adipose and liver tissue. Proteomic assays for the phosphorylation events that characterize the activated or deactivated state of the kinase-driven signaling cascades in visceral adipose tissue (VAT) could shed light on the pathogenesis of nonalcoholic steatohepatitis (NASH) and related fibrosis. Reverse-phase protein microarrays (RPMA) were used to develop biomarkers for NASH and fibrosis using VAT collected from 167 NAFLD patients (training cohort, N = 117; testing cohort, N = 50). Three types of models were developed for NASH and advanced fibrosis: clinical models, proteomics models, and combination models. NASH was predicted by a model that included measurements of two components of the insulin signaling pathway: AKT kinase and insulin receptor substrate 1 (IRS1). The models for fibrosis were less reliable when predictions were based on phosphoproteomic, clinical, or the combination data. The best performing model relied on levels of the phosphorylation of GSK3 as well as on two subunits of cyclic AMP regulated protein kinase A (PKA). Phosphoproteomics technology could potentially be used to provide pathogenic information about NASH and NASH-related fibrosis. This information can lead to a clinically relevant diagnostic/prognostic biomarker for NASH.

  5. Novel algorithm for non-invasive assessment of fibrosis in NAFLD.

    Full Text Available INTRODUCTION: Various conditions of liver disease and the downsides of liver biopsy call for a non-invasive option to assess liver fibrosis. A non-invasive score would be especially useful to identify patients with slow advancing fibrotic processes, as in Non-Alcoholic Fatty Liver Disease (NAFLD, which should undergo histological examination for fibrosis. PATIENTS/METHODS: Classic liver serum parameters, hyaluronic acid (HA and cell death markers of 126 patients undergoing bariatric surgery for morbid obesity were analyzed by machine learning techniques (logistic regression, k-nearest neighbors, linear support vector machines, rule-based systems, decision trees and random forest (RF. Specificity, sensitivity and accuracy of the evaluated datasets to predict fibrosis were assessed. RESULTS: None of the single parameters (ALT, AST, M30, M60, HA did differ significantly between patients with a fibrosis score 1 or 2. However, combining these parameters using RFs reached 79% accuracy in fibrosis prediction with a sensitivity of more than 60% and specificity of 77%. Moreover, RFs identified the cell death markers M30 and M65 as more important for the decision than the classic liver parameters. CONCLUSION: On the basis of serum parameters the generation of a fibrosis scoring system seems feasible, even when only marginally fibrotic tissue is available. Prospective evaluation of novel markers, i.e. cell death parameters, should be performed to identify an optimal set of fibrosis predictors.

    Full Text Available Chronic hepatitis C virus (HCV infection is an important cause of morbidity and mortality in people coinfected with human immunodeficiency virus (HIV. Several studies have shown that HIV infection promotes accelerated HCV hepatic fibrosis progression, even with HIV replication under full antiretroviral control. The pathogenesis of accelerated hepatic fibrosis among HIV/HCV coinfected individuals is complex and multifactorial. The most relevant mechanisms involved include direct viral effects, immune/cytokine dysregulation, altered levels of matrix metalloproteinases and fibrosis biomarkers, increased oxidative stress and hepatocyte apoptosis, HIV-associated gut depletion of CD4 cells, and microbial translocation. In addition, metabolic alterations, heavy alcohol use, as well drug use, may have a potential role in liver disease progression. Understanding the pathophysiology and regulation of liver fibrosis in HIV/HCV co-infection may lead to the development of therapeutic strategies for the management of all patients with ongoing liver disease. In this review, we therefore discuss the evidence and potential molecular mechanisms involved in the accelerated liver fibrosis seen in patients coinfected with HIV and HCV.

    Full Text Available El neoliberalismo ha supuesto una transformación en la conceptualización de las clases sociales y una reconfiguración de las relaciones entre ellas. En tal sentido, ha emprendido un cambio en los centros urbanos, intensificando su uso comercial y turístico a partir de la inversión pública en la imagen de la ciudad. En Madrid, entre los años 1998 y 2007, de hegemonía neoliberal, se ha invertido, precisamente, en proyectos que han cambiado la escena urbana, reforzando el carácter fetichista del espacio y fomentando, con ello, el reforzamiento de los valores de excelencia y prestigio social. A partir del análisis de la inversión pública en proyectos de escena urbana, se procede a estudiar aquí los efectos que las peatonalizaciones y semipeatonalizaciones han tenido en la conceptualización del centro de Madrid, en los años de máxima expansión neoliberal.

    Full Text Available The Junta de Information organised in 1866 by the Spanish authorities brought together in Madrid official representatives and people from the Antilles to discuss an essential topic: the situation of Cuba and Puerto Rico. Their complaints and petitions were specific, leaving no doubt as to what Cubans and Puerto Ricans desired. They wished for, on the one hand, the abolition of slavery, and on the other, greater political freedom: in sum, a series of social, economic and political reforms. In reponse, the Spanish authorities displayed an inflexible and intransigent disposition, which did not help the understanding between Antillas and the Spanish. The Spanish authorities responded by increasing direct taxes and rejecting the abolition of customs. On the political front, Spain maintained its extreme defense of the «statu quo». The commissioners from the Antilles found confirmed in Madrid the metropolis's lack of interest towards Cuban and Puerto Rican problems. The situation became irreversible once the independence movement had begun, wiht the objective of achieving freedom from Spanish colonialism.

    There is a large body of evidence that nitric oxide (NO) formation is implicated in mediating silica-induced pulmonary fibrosis. As a reactive free radical, NO may not only contribute to lung parenchymal tissue injury but also has the ability to combine with superoxide and form a highly reactive toxic species peroxynitrite that can induce extensive cellular toxicity in the lung tissues. This study aimed to explore the effect of agmatine, a known NO synthase inhibitor, on silica-induced pulmonary fibrosis in rats. Male Sprague Dawley rats were treated with agmatine for 60 days following a single intranasal instillation of silica suspension (50 mg in 0.1 ml saline/rat). The results revealed that agmatine attenuated silica-induced lung inflammation as it decreased the lung wet/dry weight ratio, protein concentration, and the accumulation of the inflammatory cells in the bronchoalveolar lavage fluid. Agmatine showed antifibrotic activity as it decreased total hydroxyproline content of the lung and reduced silica-mediated lung inflammation and fibrosis in lung histopathological specimen. In addition, agmatine significantly increased superoxide dismutase (p Agmatine also reduced silica-induced overproduction of pulmonary nitrite/nitrate as well as tumor necrosis factor α. Collectively, these results demonstrate the protective effects of agmatine against the silica-induced lung fibrosis that may be attributed to its ability to counteract the NO production, lipid peroxidation, and regulate cytokine effects. © The Author(s) 2014.

    This paper explores the importance of heterogeneity in value of time when assessing the viability of a new road infrastructure to alleviate congestion problems. The Spanish government has developed a congestion pricing demonstration entering Madrid city centre, where road users have to choose between a free but highly congested road and a priced free-flowing road. We consider a continuum of users who differ in their value of time. Users dislike congestion and this is more so the more a user v...

    Patients with chronic hypoxaemia develop secondary polycythaemia that improves oxygen-carrying capacity. Therefore, normal haemoglobin and haematocrit values in the presence of chronic arterial hypoxaemia in cystic fibrosis constitute \\'relative anaemia\\'. We sought to determine the cause of this relative anaemia in patients with cystic fibrosis. We studied haematological indices and oxygen saturation in healthy volunteers (n=17) and in adult patients with cystic fibrosis (n=15). Patients with cystic fibrosis had lower resting arterial oxygen saturation when compared with normal volunteers (P<0.0001), and exercise led to a greater reduction in arterial oxygen saturation (P<0.0001). However, haemoglobin and haematocrit values in patients with cystic fibrosis did not significantly differ from normal volunteers. Serum iron (P=0.002), transferrin (P=0.02), and total iron-binding capacity (P=0.01) were lower in patients with cystic fibrosis. There were no significant differences in serum ferritin, percentage iron saturation, serum erythropoietin or red cell volume between the groups. The data presented demonstrate a characteristic picture of anaemia of chronic disease in adult patients with cystic fibrosis, except for normal haemoglobin and haematocrit values. Normal haemoglobin and haematocrit values in patients with cystic fibrosis appear to represent a combination of the effects of arterial hypoxaemia promoting polycythaemia, counterbalanced by chronic inflammation promoting anaemia of chronic disease.

    Idiopathic pulmonary fibrosis is a fibrosing interstitial pneumonia associated with the radiological and/or histological pattern of usual interstitial pneumonia. Its aetiology is unknown, but probably comprises the action of endogenous and exogenous micro-environmental factors in subjects with genetic predisposition. Its diagnosis is based on the presence of characteristic findings of high-resolution computed tomography scans and pulmonary biopsies in absence of interstitial lung diseases of other aetiologies. Its clinical evolution is variable, although the mean survival rate is 2-5 years as of its clinical presentation. Patients with idiopathic pulmonary fibrosis may present complications and comorbidities which modify the disease's clinical course and prognosis. In the mild-moderate disease, the treatment consists of the administration of anti-fibrotic drugs. In severe disease, the best therapeutic option is pulmonary transplantation. In this paper we review the diagnostic and therapeutic aspects of the disease. Copyright © 2016 Elsevier España, S.L.U. All rights reserved.

    Myofibroblasts are associated with organ fibrosis, but their precise origin and functional role remain unknown. We used multiple genetically engineered mice to track, fate map and ablate cells to determine the source and function of myofibroblasts in kidney fibrosis. Through this comprehensive analysis, we identified that the total pool of myofibroblasts is split, with 50% arising from local resident fibroblasts through proliferation. The nonproliferating myofibroblasts derive through differentiation from bone marrow (35%), the endothelial-to-mesenchymal transition program (10%) and the epithelial-to-mesenchymal transition program (5%). Specific deletion of Tgfbr2 in α-smooth muscle actin (αSMA)(+) cells revealed the importance of this pathway in the recruitment of myofibroblasts through differentiation. Using genetic mouse models and a fate-mapping strategy, we determined that vascular pericytes probably do not contribute to the emergence of myofibroblasts or fibrosis. Our data suggest that targeting diverse pathways is required to substantially inhibit the composite accumulation of myofibroblasts in kidney fibrosis.

The results indicated that DCM exhibited superior performance in reducing liver collagen accumulation, mitigating liver injuries, inhibiting proinflammatory factors and fibrosis-related factor (TGF-β1, Smad2/3, α-SMA, COL1A1 expression compared with UCM. DOW, cordycepin, and adenosine also performed antiliver fibrosis effect. Therefore, because DCM is rich in DOW and functional components, it can achieve anti-liver fibrosis effects through multiple pathways. These ameliorative effects are considerably superior to those of UCM.

    To evaluate the usefulness of diffusion- weighted MRI (DWI) in the detection and staging of liver fibrosis and inflammation. DWI was performed with b-factors of 0, 500 and 1000 s/mm{sup 2}. ADC values were obtained by placing circular regions of interest in four segments of the liver. Differences between the study (n = 34) and control groups' (n = 25) ADC values were examined. Further, this study investigated if and how ADC values were related to fibrosis stages and histological activity index (HAI) scores. The mean ADC value of the liver was smaller in the study group compared with the control group (P < 0.001). Spearman rho correlation analyses showed lower ADC values were associated with higher fibrosis and HAI scores (P < 0.01). There were statistically significant differences in liver ADC values between each combination of fibrosis stages (e.g. stages 0 and 1, 0 and 2) except for stages 1 and 2. ADC values prove to be a valuable technique for the diagnosis of liver fibrosis and inflammation. They can also be useful in fibrosis staging, particularly in distinguishing later stages of fibrosis from intermediate and early stages. (orig.)

    Full Text Available The current rate of consumption is much higher than the ecology capacity of our environment. This is substantially important in cities where the imbalance of metabolic fluxes is greater. In this sense, to promote responsible consumption is the key to look for the urban sustainability, where the major communication messages are based on the current consumer society. Therefore we ask: what messages of responsible consumption are in the city? what discourses and practices related to responsible consumption are in Madrid? This work is an exploratory approach to that context and we use the technique of drift (28 drifts out in 2009 and distributed in four districts of the city of Madrid. We identify multiple and diverse discourses and practices associated with responsible consumption, especially in areas such as mobility, energy and water consumption or the use of time and space.Escuchar

    Anaerobic bacteria are not only normal commensals, but are also considered opportunistic pathogens and have been identified as persistent members of the lower airway community in people with cystic fibrosis of all ages and stages of disease. Currently, the role of anaerobic bacteria in cystic fibrosis lower airway disease is not well understood. Therefore, this review describes the recent studies relating to the potential pathophysiological role(s) of anaerobes within the cystic fibrosis lungs. The most frequently identified anaerobic bacteria in the lower airways are common to both cystic fibrosis and healthy lungs. Studies have shown that in cystic fibrosis, the relative abundance of anaerobes fluctuates in the lower airways with reduced lung function and increased inflammation associated with a decreased anaerobic load. However, anaerobes found within the lower airways also produce virulence factors, may cause a host inflammatory response and interact synergistically with recognized pathogens. Anaerobic bacteria are potentially members of the airway microbiota in health but could also contribute to the pathogenesis of lower airway disease in cystic fibrosis via both direct and indirect mechanisms. A personalized treatment strategy that maintains a normal microbial community may be possible in the future.

    Objective: To investigate the correlationship between blood hepatic fibrosis markers and blood lipids levels. Methods: Serum hepatic fibrosis markers (HA, PC III, IV-C, LN) levels were determined with RIA and serum lipids (TG, TCh HDL; LDL, apoA1, apoB) were measured with biochemical methods in 98 patients with hepatitis in various stages and 50 controls. Liver biopsy was done in all the hepatitis patients. Results: Hepatic fibrosis was classified into 5 grades (S0-S4) according to the pathology shown in the biopsy specimen. The serum lipid levels decreased along with the increase of severity of fibrosis from S0 to S4. Levels in S4 patients were significantly lower than those in controls (P 0.05). Conclusion: The serum hepatic fibrosis markers levels increased and lipids levels decreased along with the progress of hepatitis from acute to cirrhosis. (authors)

  6. Nephrogenic systemic fibrosis (NSF) and gadolinium-based contrast ...

    African Journals Online (AJOL)

    Nephrogenic systemic fibrosis (NSF), unknown before March 1997 and first described in 2000, is a systemic disorder characterised by widespread tissue fibrosis. The first known case occurred in 1997, after the use of gadolinium-based contrast agents (GBCAs) at high doses in patients with renal failure had become routine.

    Gluteal muscle fibrosis with hip contracture is a rare condition and causes major disability; literature reports are sparse. The aim of this study is to present, for the first time in Iraq and the region, a case series of gluteal fibrosis and the results of surgical treatment. Seven children--six boys and one girl--diagnosed as having gluteal muscle fibrosis with hip contracture, were investigated and treated by open surgical release of fibrotic bands and physiotherapy. All patients improved dramatically over the subsequent weeks, and were able to sit and squat in the normal position. Gluteal muscle fibrosis with hip contracture is present in Iraq and more awareness is needed for early diagnosis. Surgical treatment provided excellent results. More studies are needed to delineate the aetiology of the condition.

    Radiographic evidence of chronic interstitial lung changes, usually believed to be attributable to lung fibrosis, is readily recognised in canine practice. Furthermore, there is a body of anecdotal evidence suggesting that a specific clinical entity consistent with chronic lung fibrosis occurs in specific breeds of terrier dogs. However, there is little pathological data to confirm these radiographic and clinical findings and, therefore, chronic interstitial lung disease of dogs is poorly characterised. In this report, a case of chronic pulmonary fibrosis is described in which histopathological confirmation was possible, and suggested that the condition might be analogous to idiopathic pulmonary fibrosis (cryptogenic fibrosing alveolitis) in humans.

    The Autonomous Community of Madrid Epidemiological Bulletin is the main communications link between epidemiological monitoring system and health care professionals. The purpose of this study is that of ascertaining the dissemination and opinion of this Autonomous Community of Madrid Epidemiological Bulletin among primary care physicians for the purpose of adapting this publication to its readers' interests. A telephone survey among primary care physicians in the Autonomous Community of Madrid, asking how often they read the Bulletin, the interest and usefulness of the information included in it. The sample size was estimated at 346 physicians. A two-stage sampling process was carried out-by cluster sampling in the first stage, randomly selecting 125 health care centers and 2.7 physicians per center, 17% being primary care team coordinators. A comparison is made of the results among physicians and coordinators by means of the Chi-square and Fisher's Exact Test method, with Epi-Info v.6. A total of 305 surveys were conducted (245 physicians and 60 coordinators). There was an awareness of the existence of the Autonomous Community of Madrid Epidemiological Bulletin on the part of 91.5% (CI 95%: 88.1-94.8), and 27.2% (CI 95%: 21.9-32.5) were familiar with more than 50% of the last issues published. A total of 92.4% (CI 95%: 89.4-95.8) considered the Bulletin to be interesting or highly interesting, grading its usefulness an average of 3.5 on a maximum scale of 5. Of the permanent sections, the most highly-valued was Epidemic Outbreaks, those reports related to meningococcal infection, tuberculosis and HIV/AIDS being the most highly-valued. The Autonomous Community of Madrid Epidemiological Bulletin is a publication which, although not widely-known by the primary care physicians in the Community, is well-valued when it is read, thus being a useful feedback tool within the Epidemiological Monitoring System.

    Full Text Available Introduction: Lead is a toxic element for humans, with children being the most vulnerable population.Objective: To find out the risk factors associated to the existing blood lead levels (BLLs of children in the Community of Madrid, after 9 years of lead being banned in gasoline.Methods: A cross-sectional study was carried out in 2010 with a sample of 85 children, less than 15 years of age, recruited via the outpatients’ service of the Pediatrics Department of the Hospital Clínico San Carlos in Madrid. Routine blood tests provided the opportunity for determining other blood parameters. Lead levels were measured using electrothermal-atomization atomic absorption spectrometry with the Zeeman-effect background correction. In addition, a survey was undertaken directed to the parents for gathering information about a series of socioeconomic and environmental variables.Results: The arithmetic mean of the BLLs in the children was 1.1 μg/dL (SD=0.7 μg/dL with a range from 0.1 μg/dL to 3.4 μg/dL. The geometric mean was 0.9 μg/dL (SD= 1.1 μg/dL. The risk factors associated to these BLLs are the following: playing in the street; low educational level of the parents; leisure activities of one of the parents linked to lead; tobacco smoking of the father; and drinking tap water.Conclusions: The BLLs of the children in the Community of Madrid have decreased, but there are still sociodemographic and environmental risk factors associated to the present levels.

    A study on daily concentration changes of polycyclic aromatic and aliphatic hydrocarbons (PAH's and AH's), was carried out in aerosols sampled m the Ciudad Universitaria of Madrid. Samples were taken at morning and night during February and June, for short sampling times, on glass fiber filters in Hi-Vol samplers, and then extracted ultrasonically with cyclohexane. Analysis were performed by HRGC with fused-silica capillary columns. The variable traffic rate, and the strong influence during winter periods of domestic heating are characteristic of this place. The aim of this work was to evaluate diurnal and seasonal variations of selected AH and PAH in the urban area of Madrid, by using descriptive parameters, such as total concentrations of AH and PAH, characteristic profiles and predominance carbon index.

    The “qanat” is an ingenious system of collecting and conducting groundwater to a supply point. Its origin dates back to 3000 years ago in the area known today as Armenia, and it had spread widely throughout Persia by 600 BC. The expansion of Islam spread this technique from China to the Iberian Peninsula, where it has received various local names. In Madrid, the technique was widely used for water supply from the ninthcentury until the mid-twentieth century, and in recent centuries received the name “Viajes de agua”. However, the geological and socio-economic environment of the Sierra de Guadarrama in Madrid is not, and has never been, appropriate for the implementation of this type of water catchment. This is why the qanat supply of the former Charterhouse of Santa María de El Paular (Rascafría), which shows a very similar typology to the “Viajes de agua”, modified or constructed in Madrid between the 17th and 19th centuries, is so original. Three “capirotes” (hoods) and a “distribution ark” have been located “in situ” in the vicinity of the Monastery and another “capirote” is used as an ornamental element in the courtyard of the old Hotel El Paular. In this paper we present the results obtained in the field study and files on this “Viaje de agua”, its context within the old Monastery supply, its water quality and various hydrological and hydraulic considerations.

  17. Fibrocytes in pulmonary fibrosis: a brief synopsis

    Directory of Open Access Journals (Sweden)

    Shyam Maharaj

    2013-12-01

    Full Text Available Fibrocytes are bone marrow-derived, circulating mesenchymal progenitor cells that play a role in several fibrotic disorders, including lung fibrosis. They are attracted to injured tissue by various chemokines. It is likely that fibrocytes play a detrimental role in tissue homeostasis and promote fibrosis, although this paradigm needs further confirmation. This would make fibrocytes a possible novel treatment target for fibrotic disorders. Fibrocytes also have some potential as a biomarker for idiopathic pulmonary fibrosis (IPF and other diseases, but the promising preliminary data from single centre studies still require independent validation. Despite several, as yet, unresolved issues, it has become clear that fibrocytes are more than an incidental finding in lung injury and repair, and may hold great promise for the future of IPF management.

  18. Retroperitoneal fibrosis with pancreatic involvement – radiological appearance

    2011-01-01

    Retroperitoneal fibrosis or Ormond’s disease is an uncommon process characterized by fibrous tissue proliferation in the retroperitoneum, usually involving the aorta, inferior vena cava and iliac vessels. Obstructive hydronephrosis is often observed due to ureteral entrapment. This report presents a case of the peripancreatic location of the disease. The role of CT and MRI in establishing diagnosis of retroperitoneal fibrosis in an atypical site is discussed. A 52-year-old woman with Hashimoto’s thyroiditis was admitted to hospital because of pain suggesting renal colic. The patient was subjected to ultrasound, CT, and MRI which did not confirm urolithiasis but revealed pancreatic infiltration. Partial pancreatectomy, left-sided adrenalectomy and splenectomy were performed. Retroperitoneal fibrosis was diagnosed in the histopathological examination. A few weeks after surgery, a complication such as pancreatitis developed. Repeat CT confirmed it and showed right hydronephrosis secondary to ureteral involvement by a mass adjacent to the common iliac artery (defined as a typical manifestation of retroperitoneal fibrosis). Nephrostomy and conservative treatment improved the clinical state of the patient. No progression of the process was observed in the follow-up examinations. Atypical retroperitoneal fibrosis remains a diagnostic challenge. Imaging techniques CT and MRI are useful tools for evaluating the extent of Ormond’s disease. An unusual distribution of the process (e.g. peripancreatic location reported in this study) requires histopathological assessment to establish the final diagnosis

    Myocardial fibrosis can arise from a range of pathological processes and its presence correlates with adverse clinical outcomes. Cardiac magnetic resonance (CMR) can provide a non-invasive assessment of cardiac structure, function, and tissue characteristics, which includes late gadolinium enhancement (LGE) techniques to identify focal irreversible replacement fibrosis with a high degree of accuracy and reproducibility. Importantly the presence of LGE is consistently associated with adverse outcomes in a range of common cardiac conditions; however, LGE techniques are qualitative and unable to detect diffuse myocardial fibrosis, which is an earlier form of fibrosis preceding replacement fibrosis that may be reversible. Novel T1 mapping techniques allow quantitative CMR assessment of diffuse myocardial fibrosis with the two most common measures being native T1 and extracellular volume (ECV) fraction. Native T1 differentiates normal from infarcted myocardium, is abnormal in hypertrophic cardiomyopathy, and may be particularly useful in the diagnosis of Anderson–Fabry disease and amyloidosis. ECV is a surrogate measure of the extracellular space and is equivalent to the myocardial volume of distribution of the gadolinium-based contrast medium. It is reproducible and correlates well with fibrosis on histology. ECV is abnormal in patients with cardiac failure and aortic stenosis, and is associated with functional impairment in these groups. T1 mapping techniques promise to allow earlier detection of disease, monitor disease progression, and inform prognosis; however, limitations remain. In particular, reference ranges are lacking for T1 mapping values as these are influenced by specific CMR techniques and magnetic field strength. In addition, there is significant overlap between T1 mapping values in healthy controls and most disease states, particularly using native T1, limiting the clinical application of these techniques at present.

  3. Localized bilateral perirenal fibrosis, a rare cause of idiopathic retroperitoneal fibrosis

    Directory of Open Access Journals (Sweden)

    2014-08-01

    Full Text Available Background: Idiopathic retroperitoneal fibrosis is an infrequent process of unknown aetiology characterised by fibrous tissue proliferation in the retroperitoneum. Even less frequent is a localized form of this disease by a proliferation of fibrous tissue around single or both kidneys.Case report: We describe a case of 46-year old man in whom medical management was started for accidentally discovered arterial hypertension, which turned out to be difficult to control.   During diagnostic work-up of hypertension, an abdominal ultrasound was obtained a year later demonstrating slight bilateral caliectasis without obvious visible cause for it. Laboratory exams have shown significantly impaired renal function, normocytic anaemia, slightly higher sedimentation rate, increased CRP and normal urinalysis. Nephrologist has decided for hospitalisation during which magnetic resonance imaging was performed  showing a few mm wide tissue coats surrounding both kidneys with fluid lying between the coat and kidney capsule. A biopsy of perirenal mass has confirmed a dense cellular lesion consisted of interweaved fascicles of spindle-shaped cells. After exclusion of tumours and other causes, a diagnosis of retroperitoneal fibrosis was confirmed. Clinical picture and laboratory data corresponded to idiopathic form of this disease. A treatment with tamoxifen was started after patient refused treatment with methylprednisolone. During tamoxifen monotherapy, there was gradual significant improvement of general symptoms, notable decline in inflammation markers, improvement of anaemia, normalisation of kidney function, and normalisation of blood pressure. Conclusion: Retroperitoneal fibrosis is still an obscure and multifaceted disease. A proper selection of diagnostic methods is the key to correct and fast diagnosis as well as good grounding for proper treatment.

    FibroMeters are blood tests for liver fibrosis with several specificities: two main diagnostic targets (fibrosis stage and area of fibrosis); adaptation to specific causes; and results confirmed by an expert system. Thus, FibroMeters comprise six different tests: one for staging and one for quantitation of liver fibrosis in each of the three main causes of chronic liver disease-chronic viral hepatitis, alcoholic liver disease (ALD) and non-alcoholic fatty liver disease (NAFLD). FibroMeters display a high overall diagnostic accuracy and are the only tests to correctly classify 100% of HCV patients without fibrosis or with cirrhosis. They have 90% predictive values in a higher proportion of patients than with other usual blood tests. A 90% correct classification is available in 100% of HCV patients with the following reliable diagnostic intervals: F0/1, F1/2, F2+/-1, F3+/-1. In real-life conditions, the reproducibility of FibroMeters is higher than that of liver biopsy or ultrasonographic elastometry. FibroMeters are robust tests with the most stable diagnostic performance across different centers. Optional tests are also available, such as a specific one for cirrhosis, which has a diagnostic accuracy of 93.0% (AUROC: 0.92) and a 100% positive predictive value for diagnosis of HCV cirrhosis. Determination by FibroMeters of the area of fibrosis - the only direct, non-invasive, quantitative measurement of liver fibrosis - are especially useful for following-up cirrhosis as it correlates well with clinical events. FibroMeters are also very accurate in HVB or HIV-HCV co-infected patients. The tests specific for ALD and NAFLD also have a high diagnostic accuracy (AUROCs: 0.96 and 0.94, respectively, for significant fibrosis).

  5. Radiation-induced pulmonary fibrosis: examination of chemokine and chemokine receptor families.

    Science.gov (United States)

    Johnston, Carl J; Williams, Jacqueline P; Okunieff, Paul; Finkelstein, Jacob N

    2002-03-01

    Fibrosis is a common outcome of chronic inflammation or injury. Pulmonary fibrosis may be the result of abnormal repair after an acute inflammatory response. The process of repair initiated by a tissue insult is largely a function of the activation of cells to produce important biological mediators such as cytokines, growth factors and chemokines, which orchestrate most aspects of the inflammatory response. Consequently, altered regulation of the production of inflammatory cell cytokines and chemokines after injury and repair likely contributes to the fibrosis. Our hypothesis is that chronic expression of specific chemokine and chemokine receptors during the fibrotic phase induced by thoracic irradiation may perpetuate the recruitment and activation of lymphocytes and macrophages, which may contribute to the development of fibrosis. Fibrosis-sensitive (C57BL/6) and fibrosis-resistant (C3H/HeJ) mice were irradiated with a single dose of 12.5 Gy to the thorax. Total lung RNA was prepared and hybridized using microarray analysis and RNase protection assays. At 26 weeks postirradiation, messages encoding the chemokines BLC (now known as Scyb13), C10 (now known as Scya6), IP-10 (now known as Scyb10), MCP-1 (now known as Scya2), MCP-3 (now known as Scya7), MIP-1gamma (now known as Scya9), and RANTES (now known as Scya5) and the chemokine receptors Ccr1, Ccr2, Ccr5 and Ccr6 were elevated in fibrosis-sensitive (C57BL/6) mice. In contrast, only the messages encoding SDF-1alpha (now known as Sdf1) and Ccr1 were elevated 26 weeks postirradiation in fibrosis-resistant (C3H/HeJ) mice. Our results point to the CC and CCR family members as the predominant chemokine responders during the development of fibrosis. These studies suggest that monocyte/macrophage and lymphocyte recruitment and activation are key components of radiation-induced fibrosis.

    Idiopathic pulmonary fibrosis is defined as chronic fibrosing interstitial pneumonia limited to the lung, with poor prognosis. The incidence has been rising in recent years probably due to improved diagnostic methods and increased life expectancy. In 2013, the SEPAR guidelines for the diagnosis and treatment for idiopathic pulmonary fibrosis were published. Since then, clinical trials and meta-analyses have shown strong scientific evidence for the use of pirfenidone and nintedanib in the treatment of idiopathic pulmonary fibrosis. In 2015, the international consensus of 2011 was updated and new therapeutic recommendations were established, prompting us to update our recommendation for the medical treatment of idiopathic pulmonary fibrosis accordingly. Diagnostic aspects and non-pharmacological treatment will not be discussed as no relevant developments have emerged since the 2013 guidelines. Copyright © 2017 SEPAR.

    Nutrition is thought to influence disease status in patients with cystic fibrosis (CF). This cross-sectional study sought to evaluate nutrient intake and anthropometric data from 64 adult outpatients with cystic fibrosis. Nutrient intake from food and supplements was compared with the Dietary Reference Intakes for 16 nutrients and outcomes influenced by nutritional status. Attention was given to vitamin D and calcium given potential skeletal implications due to cystic fibrosis. Measurements included weight, height, body composition, pulmonary function, and serum metabolic parameters. Participants were interviewed about dietary intake, supplement use, pulmonary function, sunlight exposure, and pain. The participants’ mean body mass index (±standard deviation) was 21.8±4.9 and pulmonary function tests were normal. Seventy-eight percent used pancreatic enzyme replacement for malabsorption. Vitamin D deficiency [25-hydroxyvitamin D (25OHD)<37.5 nmol/L] was common: 25 (39%) were deficient despite adequate vitamin D intake. Lipid profiles were normal in the majority, even though total and saturated fat consumption represented 33.0% and 16.8% of energy intake, respectively. Reported protein intake represented 16.9% of total energy intake (range 10%–25%). For several nutrients, including vitamin D and calcium, intake from food and supplements in many participants exceeded recommended Tolerable Upper Intake Levels. Among adults with cystic fibrosis, vitamin D deficiency was common despite reported adequate intake, and lipid profiles were normal despite a relatively high fat intake. Mean protein consumption was adequate, but the range of intake was concerning, as both inadequate or excessive intake may have deleterious skeletal effects. These findings call into question the applicability of established nutrient thresholds for patients with cystic fibrosis. PMID:18060897

    To establish typologies within Madrid's citizens (Spain) with regard to end-of-life by cluster analysis. The SPAD 8 programme was implemented in a sample from a health care centre in the autonomous region of Madrid (Spain). A multiple correspondence analysis technique was used, followed by a cluster analysis to create a dendrogram. A cross-sectional study was made beforehand with the results of the questionnaire. Five clusters stand out. Cluster 1: a group who preferred not to answer numerous questions (5%). Cluster 2: in favour of receiving palliative care and euthanasia (40%). Cluster 3: would oppose assisted suicide and would not ask for spiritual assistance (15%). Cluster 4: would like to receive palliative care and assisted suicide (16%). Cluster 5: would oppose assisted suicide and would ask for spiritual assistance (24%). The following four clusters stood out. Clusters 2 and 4 would like to receive palliative care, euthanasia (2) and assisted suicide (4). Clusters 4 and 5 regularly practiced their faith and their family members did not receive palliative care. Clusters 3 and 5 would be opposed to euthanasia and assisted suicide in particular. Clusters 2, 4 and 5 had not completed an advance directive document (2, 4 and 5). Clusters 2 and 3 seldom practiced their faith. This study could be taken into consideration to improve the quality of end-of-life care choices. Copyright © 2017 SESPAS. Publicado por Elsevier España, S.L.U. All rights reserved.

    Full Text Available BACKGROUND Oral submucous fibrosis is a disease of unknown aetiology and is a legacy of Indians. It has been variously treated both medically and surgically but neither has been found to be rewarding. Various groups have been studying the therapy schedules and aetiological association, but the conclusions have remained unclear. AIM The study aims to focus on newer surgical therapy stressing on the mechanics and use of pedicle tongue flap in the management of this condition. METHODS AND MATERIALS The study comprised of 40 patients from our outpatient department suffering from oral submucous fibrosis in the age group of 11 to 70 years. The contributory factors of oral submucous fibrosis and the symptoms of the disease were evaluated and the role of pedicle tongue flap surgery in the management of this disease which is a premalignant condition is discussed. RESULTS AND CONCLUSION Pedicle tongue flap surgery has given promising results in the treatment of trismus due to oral submucous fibrosis. After the surgery, none of our patients developed any malignant change.

    A study on daily concentration changes of polycyclic aromatic and aliphatic hydrocarbons (PAH's and AH's), was carried out in aerosols sampled m the Ciudad Universitaria of Madrid. Samples were taken at morning and night during February and June, for short sampling times, on glass fiber filters in Hi-Vol samplers, and then extracted ultrasonically with cyclohexane. Analysis were performed by HRGC with fused-silica capillary columns. The variable traffic rate, and the strong influence during winter periods of domestic heating are characteristic of this place. The aim of this work was to evaluate diurnal and seasonal variations of selected AH and PAH in the urban area of Madrid, by using descriptive parameters, such as total concentrations of AH and PAH, characteristic profiles and predominance carbon index.

    2014-06-01

    Pseudo-Bartter syndrome (PBS) describes an uncommon but well recognised complication of cystic fibrosis leading to hypochloraemic, hypokalaemic metabolic alkalosis. Pseudo-Bartter syndrome is usually seen at initial presentation or within the first two years of life in children with cystic fibrosis. Risk factors for development of PBS include warm weather conditions, severe respiratory or pancreatic disease and gastrointestinal losses (e.g. vomiting and diarrhoea). PBS is rare in older children and adolescents although epidemics have been associated with heat wave conditions in warmer climates. In this era of climate change, it is crucial that clinicians consider Pseudo-Bartter syndrome when patients with cystic fibrosis present unwell during summer. Copyright © 2014 Elsevier Ltd.

    Full Text Available Introduction This study evaluates the factors associated with the development of severe periportal fibrosis in patients with Schistosoma mansoni. Methods A cross-sectional study was conducted from April to December 2012 involving 178 patients infected with S. mansoni who were treated in the Hospital das Clínicas of Pernambuco, Brazil. Information regarding risk factors was obtained using a questionnaire. Based on the patients' epidemiological history, clinical examination, and upper abdomen ultrasound evaluation, patients were divided into 2 groups: 137 with evidence of severe periportal fibrosis and 41 patients without fibrosis or with mild or moderate periportal fibrosis. Univariate and multivariate analyses were conducted using EpiInfo software version 3.5.5. Results Illiterate individuals (30.1% and patients who had more frequent contact with contaminated water in towns in the Zona da Mata of Pernambuco (33.2% were at greater risk for severe periportal fibrosis. Based on multivariate analysis, it was determined that an education level of up to 11 years of study and specific prior treatment for schistosomiasis were preventive factors for severe periportal fibrosis. Conclusions The prevailing sites of the severe forms of periportal fibrosis are still within the Zona da Mata of Pernambuco, although there has been an expansion to urban areas and the state coast. Specific treatment and an increased level of education were identified as protective factors, indicating the need for implementing social, sanitary, and health education interventions aimed at schistosomiasis to combat the risk factors for this major public health problem.

    Chronic kidney diseases generally lead to renal fibrosis. Despite great progress having been made in identifying molecular mediators of fibrosis, the mechanism that governs renal fibrosis remains unclear, and so far no effective therapeutic antifibrosis strategy is available. Here we demonstrated that a switch of metabolism from oxidative phosphorylation to aerobic glycolysis (Warburg effect) in renal fibroblasts was the primary feature of fibroblast activation during renal fibrosis and that suppressing renal fibroblast aerobic glycolysis could significantly reduce renal fibrosis. Both gene and protein assay showed that the expression of glycolysis enzymes was upregulated in mouse kidneys with unilateral ureter obstruction (UUO) surgery or in transforming growth factor-β1 (TGF-β1)-treated renal interstitial fibroblasts. Aerobic glycolysis flux, indicated by glucose uptake and lactate production, was increased in mouse kidney with UUO nephropathy or TGF-β1-treated renal interstitial fibroblasts and positively correlated with fibrosis process. In line with this, we found that increasing aerobic glycolysis can remarkably induce myofibroblast activation while aerobic glycolysis inhibitors shikonin and 2-deoxyglucose attenuate UUO-induced mouse renal fibrosis and TGF-β1-stimulated myofibroblast activation. Furthermore, mechanistic study indicated that shikonin inhibits renal aerobic glycolysis via reducing phosphorylation of pyruvate kinase type M2, a rate-limiting glycolytic enzyme associated with cell reliance on aerobic glycolysis. In conclusion, our findings demonstrate the critical role of aerobic glycolysis in renal fibrosis and support treatment with aerobic glycolysis inhibitors as a potential antifibrotic strategy.

    Multiple evidences of soft-sediment to brittle deformation within the Pleistocene fluvial terraces of the Tagus, Jarama, Tajuña and Manzanares river valleys have been described since the middle 20th Century. Cryoturbation, hydroplastic deformations due to underlying karstic collapses or halokinesis on the substratum of neogene gypsums, and seismic shaking have been proposed to interpret these structures. These deformations are typically concentrated in the +18-20 m terrace levels, and closely linked to well-known Palaeolithic sites, in some cases overlaying and/or affecting true prehistoric settlements (i.e. Arganda, Arriaga and Tafesa sites) within the Jarama and Manzanares valleys. The affected settlements typically display acheulian lithic industry linked to the scavenging of large Pleistocene mammals (i.e. Elephas antiquus). Commonly, deformational structures are concentrated in relatively thin horizons (10-50 cm thick) bracketed by undeformed fluvial sands and gravels. The soft-sediment deformations usually consist on medium to fine sized sands injected and protruded in overlaying flood-plain clayey silts, showing a wide variety of convolutes, injections, sand-dikes, dish and pillar structures, mud volcanoes, faults and folds, some times it is possible to undertake their 3D geometrical analysis due to the exceptional conservation of the structures (Tafesa). Recent geo-archaeological prospecting on the for the Palaeolithic Site of Arriaga (South Madrid City) conducted during the year 2009, let to find out an exceptional horizon of deformation of about 1.20 m thick. It consisted on highly disturbed and pervasively liquefacted sands, which hardly can be attributed to no-seismic processes. The acheulian lithic industry of the Madrid Region have been classically attributed the Late Middle Pleistocene (Comunidad de Madrid, AUDEMA S.A. (Proyecto Arriaga-2009).

    Cystic fibrosis is the most common life-shortening recessively inherited disorder in the Caucasian population. The genetic mutation that most frequently provokes cystic fibrosis (ΔF508) appeared at least 53,000years ago. For many centuries, the disease was thought to be related to witchcraft and the "evil eye" and it was only in 1938 that Dorothy H. Andersen characterized this disorder and suspected its genetic origin. The present article reviews the pathological discoveries and diagnostic and therapeutic advances made in the last 75 years. The review ends with some considerations for the future. Copyright © 2015 Elsevier España, S.L.U. and AEEH y AEG. All rights reserved.

    The main objective of this study was to analyse the cocaine addict subgroup from the Madrid study of prevalence of dual disorders in community mental health and substance misuse services. The sample consisted of 837 outpatients from Madrid, Spain. We compared 488 subjects who had a lifetime diagnosis of cocaine abuse or dependence, and 222 subjects who did not have a cocaine substance use disorder. We used the Mini International Neuropsychiatric Interview to evaluate axis I mental disorders, and the Personality Disorder Questionnaire to evaluate personality disorders. Almost three-quarters (73.4%) of cocaine addicts had a current dual disorder. Most prevalent were mood and anxiety disorders. Almost half (49.6%) had a personality disorder. Most of them (94.9%) had other substance use disorders. Cocaine addicts did not have higher prevalence rates of dual pathology than addicts with no cocaine abuse or dependence. Cocaine addicts were associated to a diagnosis of antisocial personality disorder, agoraphobia, and post-traumatic stress disorder, and they had an early age of onset of alcohol and cannabis use. Dual pathology is no higher in cocaine addicts in treatment than in addicts who do not use cocaine, however cocaine addicts started other drugs earlier, and were associated with specific mental disorders.

    Several agents are used to clear secretions from the airways of people with cystic fibrosis. Mannitol increases mucociliary clearance, but its exact mechanism of action is unknown. The dry powder formulation of mannitol may be more convenient and easier to use compared with established agents which require delivery via a nebuliser. Phase III trials of inhaled dry powder mannitol for the treatment of cystic fibrosis have been completed and it is now available in Australia and some countries in Europe. This is an update of a previous review. To assess whether inhaled dry powder mannitol is well tolerated, whether it improves the quality of life and respiratory function in people with cystic fibrosis and which adverse events are associated with the treatment. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register which comprises references identified from comprehensive electronic databases, handsearching relevant journals and abstracts from conferences.Date of last search: 28 September 2017. All randomised controlled studies comparing mannitol with placebo, active inhaled comparators (for example, hypertonic saline or dornase alfa) or with no treatment. Authors independently assessed studies for inclusion, carried out data extraction and assessed the risk of bias in included studies. The quality of the evidence was assessed using GRADE. Six studies (reported in 50 publications) were included with a total of 784 participants.Duration of treatment in the included studies ranged from 12 days to six months, with open-label treatment for an additional six months in two of the studies. Five studies compared mannitol with control (a very low dose of mannitol or non-respirable mannitol) and the final study compared mannitol to dornase alfa alone and to mannitol plus dornase alfa. Two large studies had a similar parallel design and provided data for 600 participants, which could be pooled where data for a particular outcome and time point were

    The liver maintains an immunologically tolerant environment as a result of continuous exposure to food and bacterial constituents from the digestive tract. Hepatotropic pathogens can take advantage of this niche and establish lifelong chronic infections causing hepatic fibrosis and hepatocellular carcinoma. Macrophages (Mϕ) play a critical role in regulation of immune responses to hepatic infection and regeneration of tissue. However, the factors crucial for Mϕ in limiting hepatic inflammation or resolving liver damage have not been fully understood. In this report, we demonstrate that expression of C‐type lectin receptor scavenger receptor‐AI (SR‐AI) is crucial for promoting M2‐like Mϕ activation and polarization during hepatic inflammation. Liver Mϕ uniquely up‐regulated SR‐AI during hepatotropic viral infection and displayed increased expression of alternative Mϕ activation markers, such as YM‐1, arginase‐1, and interleukin‐10 by activation of mer receptor tyrosine kinase associated with inhibition of mammalian target of rapamycin. Expression of these molecules was reduced on Mϕ obtained from livers of infected mice deficient for the gene encoding SR‐AI (msr1). Furthermore, in vitro studies using an SR‐AI‐deficient Mϕ cell line revealed impeded M2 polarization and decreased phagocytic capacity. Direct stimulation with virus was sufficient to activate M2 gene expression in the wild‐type (WT) cell line, but not in the knockdown cell line. Importantly, tissue damage and fibrosis were exacerbated in SR‐AI–/– mice following hepatic infection and adoptive transfer of WT bone‐marrow–derived Mϕ conferred protection against fibrosis in these mice. Conclusion: SR‐AI expression on liver Mϕ promotes recovery from infection‐induced tissue damage by mediating a switch to a proresolving Mϕ polarization state. (Hepatology 2017;65:32‐43).

  7. Thermodynamic Aspects and Reprogramming Cellular Energy Metabolism during the Fibrosis Process

    Directory of Open Access Journals (Sweden)

    2017-11-01

    Full Text Available Fibrosis is characterized by fibroblast proliferation and fibroblast differentiation into myofibroblasts, which generate a relaxation-free contraction mechanism associated with excessive collagen synthesis in the extracellular matrix, which promotes irreversible tissue retraction evolving towards fibrosis. From a thermodynamic point of view, the mechanisms leading to fibrosis are irreversible processes that can occur through changing the entropy production rate. The thermodynamic behaviors of metabolic enzymes involved in fibrosis are modified by the dysregulation of both transforming growth factor β (TGF-β signaling and the canonical WNT/β-catenin pathway, leading to aerobic glycolysis, called the Warburg effect. Molecular signaling pathways leading to fibrosis are considered dissipative structures that exchange energy or matter with their environment far from the thermodynamic equilibrium. The myofibroblastic cells arise from exergonic processes by switching the core metabolism from oxidative phosphorylation to glycolysis, which generates energy and reprograms cellular energy metabolism to induce the process of myofibroblast differentiation. Circadian rhythms are far-from-equilibrium thermodynamic processes. They directly participate in regulating the TGF-β and WNT/β-catenin pathways involved in energetic dysregulation and enabling fibrosis. The present review focusses on the thermodynamic implications of the reprogramming of cellular energy metabolism, leading to fibroblast differentiation into myofibroblasts through the positive interplay between TGF-β and WNT/β-catenin pathways underlying in fibrosis.

    To validate the importance of the angiotensin II receptor isotypes and the lymphatic vessels in systemic sclerosis and idiopathic pulmonary fibrosis. We examined angiotensin II type 1 and 2 receptors and lymphatic vessels in the pulmonary tissues obtained from open lung biopsies of 30 patients with systemic sclerosis and 28 patients with idiopathic pulmonary fibrosis. Their histologic patterns included cellular and fibrotic non-specific interstitial pneumonia for systemic sclerosis and usual interstitial pneumonia for idiopathic pulmonary fibrosis. We used immunohistochemistry and histomorphometry to evaluate the number of cells in the alveolar septae and the vessels stained by these markers. Survival curves were also used. We found a significantly increased percentage of septal and vessel cells immunostained for the angiotensin type 1 and 2 receptors in the systemic sclerosis and idiopathic pulmonary fibrosis patients compared with the controls. A similar percentage of angiotensin 2 receptor positive vessel cells was observed in fibrotic non-specific interstitial pneumonia and usual interstitial pneumonia. A significantly increased percentage of lymphatic vessels was present in the usual interstitial pneumonia group compared with the non-specific interstitial pneumonia and control groups. A Cox regression analysis showed a high risk of death for the patients with usual interstitial pneumonia and a high percentage of vessel cells immunostained for the angiotensin 2 receptor in the lymphatic vessels. We concluded that angiotensin II receptor expression in the lung parenchyma can potentially control organ remodeling and fibrosis, which suggests that strategies aimed at preventing high angiotensin 2 receptor expression may be used as potential therapeutic target in patients with pulmonary systemic sclerosis and idiopathic pulmonary fibrosis.

    Full Text Available During the process of acute or chronic liver injury, hepatic stellate cells interact with various types of cells such as hepatic parenchymal cells, Kupffer cells, and liver sinusoidal endothelial cells to mediate extracellular matrix deposition and sinusoid capillarization and thus initiate the process of hepatic fibrosis. The nature of hepatic fibrosis is repair response after liver injury. Liver biopsy is regarded as the gold standard for the diagnosis of hepatic fibrosis; however, it is generally associated with the risk of bleeding and even death. Noninvasive diagnostic methods for liver fibrosis mainly include serum biomarkers, imaging techniques, and predictive statistical model, but such methods cannot completely replace liver biopsy. At present, the treatment of hepatic fibrosis focuses on the research and development of new drugs targeting primary disease, hepatic stellate cells, or balance of extracellular matrix synthesis/degradation. The research on the molecular mechanism of hepatic fibrosis provides a solid theoretical basis for exploring the treatment of hepatic fibrosis.

    Epithelial-mesenchymal transition (EMT) is involved in a variety of tissue fibroses. Fibroblasts/myofibroblasts derived from epithelial cells contribute to the excessive accumulation of fibrous connective tissue in damaged tissue, which can lead to permanent scarring or organ malfunction. Therefore, EMT-related fibrosis cannot be neglected. This review highlights the findings that demonstrate the EMT to be a direct contributor to the fibroblast/myofibroblast population in the development of tissue fibrosis and helps to elucidate EMT-related anti-fibrotic strategies, which may enable the development of therapeutic interventions to suppress EMT and potentially reverse organ fibrosis.

    Objective: The promotion role of iron on pathogenesis of hepatic fibrosis and the protective role of taurine and L-arginine against hepatic fibrosis were studied. Method: The model of rat radiation hepatic fibrosis was used. Experimental rats were divided into 0 Gy, 30 Gy, 30 Gy + iron, 30 Gy + taurine and 30 Gy + L-arginine groups. Serum iron, liver tissue hydroxyproline (Hyp) and malondialdehyde (MDA) were measured one and three months respectively after irradiation of hepatic tissue, production and distribution characteristics of hepatic tissue type I and III collagen were observed with a polarizing microscope. Results: Administration of iron agent could significantly increase hepatic tissue MDA content and serum iron concentration, one month after irradiation, hepatic tissue Hyp in 30 Gy + iron group began to increase, and collagen in hepatic tissue obviously increased. Taurine and L-arginine could reduce serum iron concentration and decrease production of hepatic fissure Hyp. Conclusion: Exogenous iron agent could promote early development of radiation hepatic fibrosis; taurine and arginine could diminish pathologic alteration of hepatic fibrosis to a certain extent

    Objective: To investigate the post-irradiation neck fibrosis in patients with nasopharyngeal carcinoma and its related factors. Methods: A total of 267 patients received conventional fractionated radiotherapy with D T 50-72 Gy on the neck a half year to 10 years ago were observed for the changes of cervical shape and functions. Results: Different degrees of post-irradiation neck fibrosis were seen in all patients. The rate of heavy degree of neck radiation fibrosis was 24.34 %, and it was 2.74% when received preventive dose on the neck. There was a very significant difference between patients who received late course of tangential irradiation on the neck and those who didn't receive (P=0.0001). The incidence of post-irradiation neck fibrosis didn't increase when patients received radiotherapy combined with chemotherapy (P=0.2678). The function of cervical muscles turned weak in patients received radiotherapy delivered by 6 MV accelerator in late course of tangential irradiation, whereas skin damage was severer in patients treated with 60 Co γ-rays. Conclusions: The incidence of heavy degree of post-irradiation neck fibrosis is high ,and is related closely to late course of tangential irradiation. The authors should avoid adopting this sort of irradiation on the neck. (authors)

    Sprague-Dawley rats were exposed for 6 h daily to 0.8 ppm of ozone and 14.4 ppm of nitrogen dioxide. Approximately 7 to 10 wk after the initiation of exposure, animals began to demonstrate respiratory insufficiency and severe weight loss. About half of the rats died between Days 55 and 78 of exposure; no overt ill effects were observed in animals exposed to filtered air, to ozone alone, or to nitrogen dioxide. Biochemical findings in animals exposed to ozone and nitrogen dioxide included increased lung content of DNA, protein, collagen, and elastin, which was about 300% higher than the control values. The collagen-specific crosslink hydroxy-pyridinium, a biomarker for mature collagen in the lung, was decreased by about 40%. These results are consistent with extensive breakdown and remodeling of the lung parenchyma and its associated vasculature. Histopathologic evaluation showed severe fibrosis, alveolar collapse, honeycombing, macrophage and mast cell accumulation, vascular smooth muscle hypertrophy, and other indications of severe progressive interstitial pulmonary fibrosis and end-stage lung disease. This unique animal model of progressive pulmonary fibrosis resembles the final stages of human idiopathic pulmonary fibrosis and should facilitate studying underlying mechanisms and potential therapy of progressive pulmonary fibrosis.

    The “qanat” is an ingenious system of collecting and conducting groundwater to a supply point. Its origin dates back to 3000 years ago in the area known today as Armenia, and it had spread widely throughout Persia by 600 BC. The expansion of Islam spread this technique from China to the Iberian Peninsula, where it has received various local names. In Madrid, the technique was widely used for water supply from the ninthcentury until the mid-twentieth century, and in recent centuries received the name “Viajes de agua”. However, the geological and socio-economic environment of the Sierra de Guadarrama in Madrid is not, and has never been, appropriate for the implementation of this type of water catchment. This is why the qanat supply of the former Charterhouse of Santa María de El Paular (Rascafría), which shows a very similar typology to the “Viajes de agua”, modified or constructed in Madrid between the 17th and 19th centuries, is so original. Three “capirotes” (hoods) and a “distribution ark” have been located “in situ” in the vicinity of the Monastery and another “capirote” is used as an ornamental element in the courtyard of the old Hotel El Paular. In this paper we present the results obtained in the field study and files on this “Viaje de agua”, its context within the old Monastery supply, its water quality and various hydrological and hydraulic considerations.

    Background: NLRC5, as the largest member of NLRs family, has recently been identified as a critical regulator of immune responses through negatively regulating NF-κB which is associated with the development of hepatic fibrosis. However, the expression and potential roles of NLRC5 in hepatic fibrosis and its reversal are still to be defined. Methods: C57BL/6 mice were treatment with carbon tetrachloride (CCl{sub 4}) induce hepatic fibrosis and its reversal. In vitro, models of hepatic fibrosis and its reversal are established by the treatment with TGF-β and MDI. The expression of NLRC5 was determined by RT-PCR, Western blot and immunohistochemistry. Consequently, NLRC5 was overexpressed or knockdown by transfecting PEGFP-C2-NLRC5 or NLRC5-siRNA respectively in the reversal of hepatic fibrosis, and the expression of fibrogenic genes such as α-SMA and Col1α1 was quantified. The NF-κB activity was detected as well. Results: Immunohistochemistry, RT-PCR and Western blot analysis with liver tissues and primary HSCs showed that NLRC5 was highly expressed in hepatic fibrosis and correspondingly decreased in the reversal stage. The differential expression of NLRC5 was confirmed in vitro. Enforced NLRC5 expression increased the expression of α-SMA and Col1α1, and blockade of NLRC5 reduced the fibrotic response. While the opposite expression of phosphorylated NF-kB p65 and phospho-IκBα was found. Conclusion: NLRC5 is differentially expressed in hepatic tissues and hepatic stellate cells during hepatic fibrosis and its reversal. All the data indicated that NLRC5 may play a crucial role in regulating the reversal of hepatic fibrosis through NF-κB signaling pathway. - Highlights: • The activated HSCs can be reverted to quiescent HSCs by MDI treatment. • NLRC5 expressed differentially during different stages of hepatic fibrosis and its reversal. • Enforced NLRC5 in reverted LX-c cells boosted the expression of α-SMA and Col1α1. • Blockade of NLRC5 diminished

    To investigate whether liver fibrosis can be staged by deep learning techniques based on CT images. This clinical retrospective study, approved by our institutional review board, included 496 CT examinations of 286 patients who underwent dynamic contrast-enhanced CT for evaluations of the liver and for whom histopathological information regarding liver fibrosis stage was available. The 396 portal phase images with age and sex data of patients (F0/F1/F2/F3/F4 = 113/36/56/66/125) were used for training a deep convolutional neural network (DCNN); the data for the other 100 (F0/F1/F2/F3/F4 = 29/9/14/16/32) were utilised for testing the trained network, with the histopathological fibrosis stage used as reference. To improve robustness, additional images for training data were generated by rotating or parallel shifting the images, or adding Gaussian noise. Supervised training was used to minimise the difference between the liver fibrosis stage and the fibrosis score obtained from deep learning based on CT images (F DLCT score) output by the model. Testing data were input into the trained DCNNs to evaluate their performance. The F DLCT scores showed a significant correlation with liver fibrosis stage (Spearman's correlation coefficient = 0.48, p deep learning model based on CT images, with moderate performance. • Liver fibrosis can be staged by a deep learning model based on magnified CT images including the liver surface, with moderate performance. • Scores from a trained deep learning model showed moderate correlation with histopathological liver fibrosis staging. • Further improvement are necessary before utilisation in clinical settings.

    Cardiac fibrosis greatly impairs normal heart function post infarction and there is no effective anti-fibrotic drug developed at present. The current therapies for cardiac infarction mainly take effect by eliminating occlusion in coronary artery by thrombolysis drugs, vascular stent grafting or heart bypass operation, which are capable to provide sufficient blood flow for intact myocardium yet showed subtle efficacy in ameliorating fibrosis condition. The advances of in vitro cell/tissue models open new avenues for drug assessment due to the low cost, good controllability and availability as well as the convenience for operation as compared to the animal models. To our knowledge, no proper biomimetic in vitro cardiac fibrosis model has been reported yet. Here we engineered an in vitro cardiac fibrosis model using heart-derived fibroblasts, and the fibrogenesis was recapitulated by patterning the substrate rigidity which mimicked the mechanical heterogeneity of myocardium post-infarction. Various biomarkers for cardiac fibrosis were assayed to validate the biomimicry of the engineered platform. Subsequent addition of Rho-associated protein kinase (ROCK) pathway inhibitor reduced the ratio of myofibroblasts, indicating the feasibility of applying this platform in screening anti-fibrosis drugs.

    Cystic Fibrosis is caused by mutations in the Cystic Fibrosis Transmembrane conductance Regulator (CFTR) gene resulting in abnormal protein function. Recent advances of targeted molecular therapies and high throughput screening have resulted in multiple drug therapies that target many important mutations in the CFTR protein. In this review, we provide the latest results and current progress of CFTR modulators for the treatment of cystic fibrosis, focusing on potentiators of CFTR channel gating and Phe508del processing correctors for the Phe508del CFTR mutation. Special emphasis is placed on the molecular basis underlying these new therapies and emerging results from the latest clinical trials. The future directions for augmenting the rescue of Phe508del with CFTR modulators is also emphasized. PMID:26097168

    Membrane proteins make up ∼30% of the proteome. During the early stages of maturation, this class of proteins can experience localized misfolding in distinct cellular compartments, such as the cytoplasm, endoplasmic reticulum (ER lumen and ER membrane. ER quality control (ERQC mechanisms monitor folding and determine whether a membrane protein is appropriately folded or is misfolded and warrants degradation. ERQC plays crucial roles in human diseases, such as cystic fibrosis, in which deletion of a single amino acid (F508 results in the misfolding and degradation of the cystic fibrosis transmembrane conductance regulator (CFTR Cl– channel. We introduced the ΔF508 mutation into Caenorhabditis elegans PGP-3, a 12-transmembrane ABC transporter with 15% identity to CFTR. When expressed in intestinal epithelial cells, PGP-3wt was stable and efficiently trafficked to the apical plasma membrane through a COPII-dependent mechanism. However, PGP-3ΔF508 was post-transcriptionally destabilized, resulting in reduced total and apical membrane protein levels. Genetic or physiological activation of the osmotic stress response pathway, which causes accumulation of the chemical chaperone glycerol, stabilized PGP-3ΔF508. Efficient degradation of PGP-3ΔF508 required the function of several C. elegans ER-associated degradation (ERAD homologs, suggesting that destabilization occurs through an ERAD-type mechanism. Our studies show that the ΔF508 mutation causes post-transcriptional destabilization and degradation of PGP-3 in C. elegans epithelial cells. This model, combined with the power of C. elegans genetics, provides a new opportunity to genetically dissect metazoan ERQC.

    Full Text Available Nonalcoholic fatty liver disease (NAFLD is prevalent in 20–25% of the general population and is associated with metabolic risk factors such as obesity, diabetes mellitus, and dyslipidemia. Histologically, NAFLD ranges from simple steatosis to nonalcoholic steatohepatitis (NASH, fibrosis, and cirrhosis. As NASH develops in only 10–15% of patients with NAFLD, it is not practical to biopsy all patients who present with NAFLD. Noninvasive fibrosis tests have been extensively developed recently and offer alternatives for staging fibrosis. Despite their increasing use, such tests cannot adequately differentiate simple steatosis from NASH. At present, such tests can be used as first line tests to rule out patients without advanced fibrosis and thus prevent unnecessary secondary care referrals in a significant number of patients. In this review we present the evidence for the use of noninvasive fibrosis tests in patients with NAFLD.

    Fibrosis in the pancreas is caused by such processes as necrosis/apoptosis, inflammation or duct obstruction. The initial event that induces fibrogenesis in the pancreas is an injury that may involve the interstitial mesenchymal cells, the duct cells and/or the acinar cells. Damage to any one of these tissue compartments of the pancreas is associated with cytokine-triggered transformation of resident fibroblasts/pancreatic stellate cells into myofibroblasts and the subsequent production and deposition of extracellular matrix. Depending on the site of injury in the pancreas and the involved tissue compartment, predominantly inter(peri)lobular fibrosis (as in alcoholic chronic pancreatitis), periductal fibrosis (as in hereditary pancreatitis), periductal and interlobular fibrosis (as in autoimmune pancreatitis) or diffuse inter- and intralobular fibrosis (as in obstructive chronic pancreatitis) develops.

    Cystic fibrosis is the most common hereditary disorder among Caucasians. Most of the patients are diagnosed as children. However, some cases are going undiagnosed into adulthood and are then often misdiagnosed because the non-pediatricians do not know cystic fibrosis very well and do not consider this diagnosis in adult patients. We present the medical history of a woman, who was diagnosed with cystic fibrosis at the age of 39 years, although she had suffered from bronchiectasis, pancreatic insufficiency and liver cirrhosis since many years. Her medical history was long with some diagnosis, but because of her age nobody considered the final diagnosis. In adult patients with bronchiectasis, liver cirrhosis and pancreatic insufficiency in combination or with only one of these symptoms, cystic fibrosis should be included into the differential diagnosis.

    Full Text Available Abstract Background Our aim is to conduct an exploratory study to provide an in-depth characterization of a neighborhood’s social and physical environment in relation to cardiovascular health. A mixed-methods approach was used to better understand the food, alcohol, tobacco and physical activity domains of the urban environment. Methods We conducted this study in an area of 16,000 residents in Madrid (Spain. We obtained cardiovascular health and risk factors data from all residents aged 45 and above using Electronic Health Records from the Madrid Primary Health Care System. We used several quantitative audit tools to assess: the type and location of food outlets and healthy food availability; tobacco and alcohol points of sale; walkability of all streets and use of parks and public spaces. We also conducted 11 qualitative interviews with key informants to help understanding the relationships between urban environment and cardiovascular behaviors. We integrated quantitative and qualitative data following a mixed-methods merging approach. Results Electronic Health Records of the entire population of the area showed similar prevalence of risk factors compared to the rest of Madrid/Spain (prevalence of diabetes: 12 %, hypertension: 34 %, dyslipidemia: 32 %, smoking: 10 %, obesity: 20 %. The food environment was very dense, with many small stores (n = 44 and a large food market with 112 stalls. Residents highlighted the importance of these small stores for buying healthy foods. Alcohol and tobacco environments were also very dense (n = 91 and 64, respectively, dominated by bars and restaurants (n = 53 that also acted as food services. Neighbors emphasized the importance of drinking as a socialization mechanism. Public open spaces were mostly used by seniors that remarked the importance of accessibility to these spaces and the availability of destinations to walk to. Conclusion This experience allowed testing and refining

    Full Text Available Background & Aims: Toll-like receptor 4 (TLR4 signaling is activated through 2 adaptor proteins: MyD88 and TIR-domain containing adaptor-inducing interferon-β (TRIF. TLR4 and MyD88 are crucial in nonalcoholic steatohepatitis (NASH and fibrosis. However, the role of TRIF in TLR4-mediated NASH and fibrosis has been elusive. This study investigated the differential roles of TRIF in hepatic steatosis and inflammation/fibrosis. Methods: A choline-deficient amino acid defined (CDAA diet was used for the mouse NASH model. On this diet, the mice develop hepatic steatosis, inflammation, and fibrosis. TLR4 wild-type and TLR4-/- bone marrow chimeric mice and TRIF-/- mice were fed CDAA or a control diet for 22 weeks. Hepatic steatosis, inflammation, and fibrosis were examined. Results: In the CDAA diet–induced NASH, the mice with wild-type bone marrow had higher alanine aminotransferase and hepatic tumor necrosis factor levels than the mice with TLR4-/- bone marrow. The nonalcoholic fatty liver disease activity score showed that both wild-type and TLR4-/- bone marrow chimeras had reduced hepatic steatosis, and that both types of chimeras had similar levels of inflammation and hepatocyte ballooning to whole-body wild-type mice. Notably, wild-type recipients showed more liver fibrosis than TLR4-/- recipients. Although TRIF-/- mice showed reduced hepatic steatosis, these mice showed more liver injury, inflammation, and fibrosis than wild-type mice. TRIF-/- stellate cells and hepatocytes produced more C-X-C motif chemokine ligand 1 (CXCL1 and C-C motif chemokine ligand than wild-type cells in response to lipopolysaccharide. Consistently, TRIF-/- mice showed increased CXCL1 and CCL3 expression along with neutrophil and macrophage infiltration, which promotes liver inflammation and injury. Conclusions: In TLR4-mediated NASH, different liver cells have distinct roles in hepatic steatosis, inflammation, and fibrosis. TRIF promotes hepatic

    The aberrant fibrotic and repair responses in the lung are major hallmarks of idiopathic pulmonary fibrosis (IPF). Numerous antifibrotic strategies have been used in the clinic with limited success, raising the possibility that an effective therapeutic strategy in this disease must inhibit fibrosis and promote appropriate lung repair mechanisms. IL-13 represents an attractive target in IPF, but its disease association and mechanism of action remains unknown. In the present study, an overexpression of IL-13 and IL-13 pathway markers was associated with IPF, particularly a rapidly progressive form of this disease. Targeting IL-13 in a humanized experimental model of pulmonary fibrosis using tralokinumab (CAT354) was found to therapeutically block aberrant lung remodeling in this model. However, targeting IL-13 was also found to promote lung repair and to restore epithelial integrity. Thus, targeting IL-13 inhibits fibrotic processes and enhances repair processes in the lung.

    To determine which abdominal CT findings predict severe fibrosis and post-operative pain relief in chronic pancreatitis (CP). Pre-operative abdominal CTs of 66 patients (mean age 52 ± 12 years, 53 % males) with painful CP who underwent the Whipple procedure (n = 32), Frey procedure (n = 32) or pancreatic head biopsy (n = 2), between 1/2003-3/2014, were evaluated. CT was evaluated for parenchymal calcifications, intraductal calculi, main pancreatic duct dilation (>5 mm), main pancreatic duct stricture, and abnormal side branch(es). The surgical histopathology was graded for fibrosis. CT findings were evaluated as predictors of severe fibrosis and post-operative pain relief using regression and area under receiver operating curve (AUC) analysis. Thirty-eight (58 %) patients had severe fibrosis. Parenchymal calcification(s) were an independent predictor of severe fibrosis (p = 0.03), and post-operative pain relief over a mean follow-up of 1-year (p = 0.04). Presence of >10 parenchymal calcifications had higher predictive accuracy for severe fibrosis than 1-10 parenchymal calcification(s) (AUC 0.88 vs. 0.59, p = 0.003). The predictive accuracy of >10 versus 1-10 parenchymal calcifications increased after adjusting for all other CT findings (AUC 0.89 vs. 0.63, p = 0.01). Parenchymal calcification(s) independently predict severe fibrosis and are significantly associated with post-operative pain relief in CP. The presence of >10 parenchymal calcifications is a better predictor of severe fibrosis than 1-10 parenchymal calcification(s). (orig.)

The predictive accuracy of >10 versus 1-10 parenchymal calcifications increased after adjusting for all other CT findings (AUC 0.89 vs. 0.63, p = 0.01). Parenchymal calcification(s) independently predict severe fibrosis and are significantly associated with post-operative pain relief in CP. The presence of >10 parenchymal calcifications is a better predictor of severe fibrosis than 1-10 parenchymal calcification(s). (orig.)

    Significant progress has been achieved in developing precision therapies for cystic fibrosis; however, highly effective treatments that target the ion channel, CFTR, are not yet available for many patients. As numerous CFTR therapeutics are currently in the clinical pipeline, reliable screening tools capable of predicting drug efficacy to support individualized treatment plans and translational research are essential. The utilization of bronchial, nasal, and rectal tissues from individual cystic fibrosis patients for drug testing using in vitro assays such as electrophysiological measurements of CFTR activity and evaluation of fluid movement in spheroid cultures, has advanced the prediction of patient-specific responses. However, for precise prediction of drug effects, in vitro models of CFTR rescue should incorporate the inflamed cystic fibrosis airway environment and mimic the complex tissue structures of airway epithelia. Furthermore, novel assays that monitor other aspects of successful CFTR rescue such as restoration of mucus characteristics, which is important for predicting mucociliary clearance, will allow for better prognoses of successful therapies in vivo. Additional cystic fibrosis treatment strategies are being intensively explored, such as development of drugs that target other ion channels, and novel technologies including pluripotent stem cells, gene therapy, and gene editing. The multiple therapeutic approaches available to treat the basic defect in cystic fibrosis combined with relevant precision medicine models provide a framework for identifying optimal and sustained treatments that will benefit all cystic fibrosis patients.

    wound healing. PPARβ/δ agonists inhibit lung fibroblast proliferation and enhance the antifibrotic properties of PPARγ agonists. PPARγ ligands oppose the profibrotic effect of TGF-β, which induces differentiation of fibroblasts to myofibroblasts, a critical effector cell in fibrosis. PPARγ ligands, including the thiazolidinedione class of antidiabetic drugs, effectively inhibit lung fibrosis in vitro and in animal models. The clinical availability of potent and selective PPARα and PPARγ agonists should facilitate rapid development of successful treatment strategies based on current and ongoing research.

    Inactivated Orf virus (ORFV, Parapoxvirus ovis) demonstrates strong antiviral activity in animal models including a human hepatitis B virus (HBV)-transgenic mouse. In addition, expression of interferon (IFN)-γ and interleukin-10 (IL-10) was induced after administration of inactivated ORFV in these mice. IFN-γ and IL-10 are known to elicit antifibrotic activity. We therefore aimed to study antifibrotic activity of inactivated ORFV in models of liver fibrosis. We characterized ORFV-induced hepatic cytokine expression in rats. We then studied ORFV in two models of liver fibrosis in rats, pig serum-induced liver fibrosis and carbon tetrachloride (CCL4 )-induced liver fibrosis. ORFV induced hepatic expression of IFN-γ and IL-10 in rats. ORFV mediated antifibrotic activity when administrated concomitantly with the fibrosis-inducing agents in both models of liver fibrosis. Importantly, when CCL4 -induced liver fibrosis was already established, ORFV application still showed significant antifibrotic activity. In addition, we were able to demonstrate a direct antifibrotic effect of ORFV on stellate cells. These results establish a potential novel antifibrotic therapeutic approach that not only prevents but also resolves established liver fibrosis. Further studies are required to unravel the details of the mechanisms involved. © 2012 The Japan Society of Hepatology.

    Cystic fibrosis is the most common lethal autosomal recessive disorder in the Caucasian population. Although the survival rate in patients constantly improves, lung damage is still the major cause of morbidity and mortality in patients with cystic fibrosis. In clinical practice, evaluation of patients’ pulmonary state is made by combination of monitoring of lung function and more directly by assessing the lung structure in imaging studies. Studies showed that computed tomography findings are more sensitive as compared to the pulmonary function tests. Computed tomography can identify a wide range of morphological abnormalities in patients with cystic fibrosis, such as bronchiectasis (which is progressive, irreversible and probably the most relevant structural change in cystic fibrosis) peribronchial thickening, mucous plugging and many other disorders that occur in the course of the disease. Computed tomography has a crucial role in the assessment of pulmonary damage over time, detecting complications and monitoring treatment effects in patients with cystic fibrosis

Its objective is to delimit “vulnerable areas” so there can be evaluated the opportunities for interve trough them and then define the best tools in detriment of their vulnerability reasons. To determinate those areas we have developed a sociodemographic analysis where we have found those units of population with vulnerable values. Once determinated, we have synthetize them to define them as easy drafts that makes understandable the work area for later on establish a vulnerable areas catalogue with spatial homogeneity and significant size. The basic nucleus of the análisis has been the sociodemographic fact, based on homogeneus data sources for all the area so they could be referenced to specific spacial areas. In each case has been advised other possible indicators of vulnerability including a signifier selection of thrm on the fifth chapter.

    Thrombin activates hepatic stellate cells via protease-activated receptor-1. The role of Factor Xa (FXa) in hepatic fibrosis has not been elucidated. We aimed to evaluate the impact of FXa and thrombin in vitro on stellate cells and their respective inhibition in vivo using a rodent model of hepatic fibrosis. HSC-LX2 cells were incubated with FXa and/or thrombin in cell culture, stained for αSMA and relative gene expression and gel contraction calculated. C57BL/6 J mice were administered thioacetamide (TAA) for 8 weeks with Rivaroxaban (n = 15) or Dabigatran (n = 15). Control animals received TAA alone (n = 15). Fibrosis was scored and quantified using digital image analysis and hepatic tissue hydroxyproline estimated. Stellate cells treated with FXa and thrombin demonstrated upregulation of procollagen, TGF-beta, αSMA and significant cell contraction (43.48%+/- 4.12) compared to culturing with FXa or thrombin alone (26.90%+/- 8.90, p = 0.02; 13.1%+/- 9.84, p < 0.001). Mean fibrosis score, percentage area of fibrosis and hepatic hydroxyproline content (2.46 vs 4.08, p = 0.008; 2.02% vs 3.76%, p = 0.012; 276.0 vs 651.3, p = 0.0001) were significantly reduced in mice treated with the FXa inhibitor compared to control mice. FXa inhibition was significantly more effective than thrombin inhibition in reducing percentage area of fibrosis and hepatic hydroxyproline content (2.02% vs 3.70%,p = 0.031; 276.0 vs 413.1,p = 0.001). FXa promotes stellate cell contractility and activation. Early inhibition of coagulation using a FXa inhibitor significantly reduces TAA induced murine liver fibrosis and may be a viable treatment for liver fibrosis in patients.

    Full Text Available The data described in this article were collected daily over the period June 10, 2010, to November 25, 2012, from the website of the Spanish Ministry of Industry, Energy and Tourism. The database includes information about fuel stations regarding to their prices (both gross and net of taxes, brand, location (latitude and longitude, and postal code in the Spanish provinces of Madrid and Barcelona. Moreover, obtaining the postal codes has allowed us to select those stations that are operating within the metropolitan areas of Madrid and Barcelona. By considering those fuel stations that uninterruptedly provided prices during the entire period, the data can be especially useful to explore the dynamics of prices in fuel markets. This is the case of Balaguer and Ripollés (2016, “Asymmetric fuel price responses under heterogeneity” [1], who, taking into account the presence of the potential heterogeneity of the behaviour of fuel stations, used this statistical information to perform an analysis on asymmetric fuel price responses.

    To evaluate the diagnostic performance of computed tomography (CT) volumetry for discriminating the fibrosis stage in patients with nonalcoholic fatty liver disease (NAFLD). A total of 38 NAFLD patients were enrolled. On the basis of CT imaging, the volumes of total, left lateral segment (LLS), left medial segment, caudate lobe, and right lobe (RL) of the liver were calculated with a dedicated liver application. The relationship between the volume percentage of each area and fibrosis stage was analyzed using Spearman's rank correlation coefficient. A receiver operating characteristic (ROC) curve analysis was performed to determine the accuracy of CT volumetry for discriminating fibrosis stage. The volume percentages of the caudate lobe and the LLS significantly increased with the fibrosis stage ( r = 0.815, P volumetry is a useful diagnostic parameter for staging fibrosis in NAFLD patients.

    Monitoring of pulmonary physiology is fundamental to the clinical management of patients with Cystic Fibrosis. The current standard clinical practise uses spirometry to assess lung function which delivers a clinically relevant functional readout of total lung function, however does not supply any visible or localised information. High Resolution Computed Tomography (HRCT) is a well-established current 'gold standard' method for monitoring lung anatomical changes in Cystic Fibrosis patients. HRCT provides excellent morphological information, however, the X-ray radiation dose can become significant if multiple scans are required to monitor chronic diseases such as cystic fibrosis. X-ray phase-contrast imaging is another emerging X-ray based methodology for Cystic Fibrosis lung assessment which provides dynamic morphological and functional information, albeit with even higher X-ray doses than HRCT. Magnetic Resonance Imaging (MRI) is a non-ionising radiation imaging method that is garnering growing interest among researchers and clinicians working with Cystic Fibrosis patients. Recent advances in MRI have opened up the possibilities to observe lung function in real time to potentially allow sensitive and accurate assessment of disease progression. The use of hyperpolarized gas or non-contrast enhanced MRI can be tailored to clinical needs. While MRI offers significant promise it still suffers from poor spatial resolution and the development of an objective scoring system especially for ventilation assessment.

    Full Text Available Chronic liver damage leads to pathological accumulation of ECM proteins (liver fibrosis. Comprehensive characterization of the human ECM molecular composition is essential for gaining insights into the mechanisms of liver disease. To date, studies of ECM remodeling in human liver diseases have been hampered by the unavailability of purified ECM. Here, we developed a decellularization method to purify ECM scaffolds from human liver tissues. Histological and electron microscopy analyses demonstrated that the ECM scaffolds, devoid of plasma and cellular components, preserved the three-dimensional ECM structure and zonal distribution of ECM components. This method has been then applied on 57 liver biopsies of HCV-infected patients at different stages of liver fibrosis according to METAVIR classification. Label-free nLC-MS/MS proteomics and computation biology were performed to analyze the ECM molecular composition in liver fibrosis progression, thus unveiling protein expression signatures specific for the HCV-related liver fibrotic stages. In particular, the ECM molecular composition of liver fibrosis was found to involve dynamic changes in matrix stiffness, flexibility and density related to the dysregulation of predominant collagen, elastic fibers and minor components with both structural and signaling properties. This study contributes to the understanding of the molecular bases underlying ECM remodeling in liver fibrosis and suggests new molecular targets for fibrolytic strategies.

  10. Efficacies of prevention and control measures applied during an outbreak in Southwest Madrid, Spain.

    Full Text Available Leishmaniasis is a vector-borne disease of worldwide distribution, currently present in 98 countries. Since late 2010, an unusual increase of human visceral and cutaneous leishmaniasis cases has been observed in the south-western Madrid region, totaling more than 600 cases until 2015. Some hosts, such as human, domestic dog and cat, rabbit (Oryctolagus cuniculus, and hare (Lepus granatensis, were found infected by the parasite of this disease in the area. Hares were described as the most important reservoir due to their higher prevalence, capacity to infect the vector, and presence of the same strains as in humans. Various measures were adopted to prevent and control the disease, and since 2013 there was a slight decline in the human sickness. We used a mathematical model to evaluate the efficacy of each measure in reducing the number of infected hosts. We identified in the present model that culling both hares and rabbits, without immediate reposition of the animals, was the best measure adopted, decreasing the proportion of all infected hosts. Particularly, culling hares was more efficacious than culling rabbits to reduce the proportion of infected individuals of all hosts. Likewise, lowering vector contact with hares highly influenced the reduction of the proportion of infected hosts. The reduction of the vector density per host in the park decreased the leishmaniasis incidence of hosts in the park and the urban areas. On the other hand, the reduction of the vector density per host of the urban area (humans, dogs and cats decreased only their affected population, albeit at a higher proportion. The use of insecticide-impregnated collar and vaccination in dogs affected only the infected dogs' population. The parameters related to the vector contact with dog, cat or human do not present a high impact on the other hosts infected by Leishmania. In conclusion, the efficacy of each control strategy was determined, in order to direct future actions

    The topic of the review article [1] is the derivation of a multiscale paradigm for the modeling of fibrosis. Firstly, the biological process of the physiological and pathological fibrosis including therapeutical actions is reviewed. Fibrosis can be a consequence of tissue damage, infections and autoimmune diseases, foreign material, tumors. Some questions regarding the pathogenesis, progression and possible regression of fibrosis are lacking. At each scale of observation, different theoretical tools coming from computational, mathematical and physical biology have been proposed. However a complete framework that takes into account the different mechanisms occurring at different scales is still missing. Therefore with the main aim to define a multiscale approach for the modeling of fibrosis, the authors of [1] have presented different top-down and bottom-up approaches that have been developed in the literature. Specifically, their description refers to models for fibrosis diseases based on ordinary and partial differential equation, agents [2], thermostatted kinetic theory [3-5], coarse-grained structures [6-8] and constitutive laws for fibrous collagen networks [9]. A critical analysis has been addressed for all frameworks discussed in the paper. Open problems and future research directions referring to both biological and modeling insight of fibrosis are presented. The paper concludes with the ambitious aim of a multiscale model.

    This article describes the case of a 16-year-old boy with cystic fibrosis who presented with difficulty seeing in the dark. He had a history of bowel surgery at birth, and he developed cystic fibrosis liver disease and osteopenia during his teenage years. He always had good lung function. When his serum vitamin A level was checked, it was undetectable in sample. He was diagnosed with night blindness and commenced on high-dose vitamin A. His symptoms resolved within 3 days. However, it took over 1 year for his vitamin A level to return to normal. This case emphasizes the importance of monitoring vitamin levels in cystic fibrosis to detect deficiency and prevent long-term consequences, and it highlights the challenges encountered during the course of night blindness treatment.

    Patients with biopsy-proven NASH and especially those with fibrosis are at risk for progressive liver disease, emphasizing the clinical importance of developing non-invasive biomarkers for NASH and NASH-related fibrosis. This study examines the performance of a new biomarker panel for NASH and NASH-related fibrosis with a combination of clinical and laboratory variables. Enrolled patients had biopsy-proven NAFLD. Clinical data, laboratory data, and serum samples were collected at the time of biopsy. Fasting serum was assayed for adiponectin, resistin, glucose, M30, M65, Tissue inhibitor of metalloproteinases-1 (Timp-1), ProCollagen 3 N-terminal peptide (PIIINP), and hyaluronic acid (HA). Regression models predictive of NASH, NASH-related fibrosis, and NASH-related advanced fibrosis were designed and cross-validated. Of the 79 enrolled NAFLD patients, 40 had biopsy-proven NASH and 39 had non-NASH NAFLD. Clinical and laboratory data were from this cohort were used to develop a NAFLD Diagnostic Panel that includes three models (models for NASH, NASH-related fibrosis, and NASH-related advanced fibrosis). The model for predicting NASH includes diabetes, gender, BMI, triglycerides, M30 (apoptosis), and M65-M30 (necrosis) [AUC: 0.81, 95% CI, 0.70-0.89, 300 p value <9E 301 (-06)]. The NASH-related fibrosis prediction model includes the same predictors [AUC: 0.80, 95% CI 0.68-0.88, 307 p value <0.00014]. Finally, the NASH-related advanced fibrosis model includes type 2 diabetes, serum triglycerides, Timp-1, and AST [AUC: 0.81, 95% CI, 0.70-0.89; p value, 0.000062]. This NAFLD Diagnostic Panel based on a clinical and laboratory data has good performance characteristics and is easy to use. This biomarker panel could become useful in the management of patients with NAFLD.

    Virtually all chronic liver injuries result in the activation of hepatic stellate cells (HSCs). In their activated state, these cells are the main collagen-producing cells implicated in liver fibrosis. Capsaicin (CPS), the active compound of chili peppers, can modulate the activation and migration of HSCs in vitro. Here, we evaluated the potential protective and prophylactic effects of CPS related to cholestatic and hepatotoxic-induced liver fibrosis and its possible underlying mechanism of action. Male Balb/c mice received dietary CPS after 3 days of bile duct ligation (BDL) or before and during carbon tetrachloride (CCl4 ) injections. Mice receiving dietary CPS after BDL had a significant improvement of liver fibrosis accompanied by a decrease in collagen deposition and downregulation of activation markers in isolated HSCs. In the CCl4 model, dietary CPS inhibited the upregulation of profibrogenic markers. However, CPS could not attenuate the CCl4 -induced fibrosis when it was already established. Furthermore, in vitro CPS treatment inhibited the autophagic process during HSC activation. Dietary CPS has potential benefits in the therapy of cholestatic liver fibrosis and in the prophylaxis of hepatotoxic-induced liver injury. © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    Cholestatic liver disease is characterized by the progressive destruction of biliary epithelial cells (BECs) followed by fibrosis, cirrhosis and liver failure. Activated hepatic stellate cells (HSCs) and portal fibroblasts are the major cellular effectors of enhanced collagen deposition in biliary fibrosis. Apamin, an 18 amino acid peptide neurotoxin found in apitoxin (bee venom), is known to block Ca2+-activated K+ channels and prevent carbon tetrachloride-induced liver fibrosis. In the present study, we aimed to ascertain whether apamin inhibits biliary fibrosis and the proliferation of HSCs. Cholestatic liver fibrosis was established in mouse models with 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DDC) feeding. Cellular assays were performed on HSC-T6 cells (rat immortalized HSCs). DDC feeding led to increased hepatic damage and proinflammtory cytokine levels. Notably, apamin treatment resulted in decreased liver injury and proinflammatory cytokine levels. Moreover, apamin suppressed the deposition of collagen, proliferation of BECs and expression of fibrogenic genes in the DDC-fed mice. In HSCs, apamin suppressed activation of HSCs by inhibiting the Smad signaling pathway. These data suggest that apamin may be a potential therapeutic target in cholestatic liver disease.

  16. TINF2 Gene Mutation in a Patient with Pulmonary Fibrosis

    Full Text Available Pulmonary fibrosis is a frequent manifestation of telomere syndromes. Telomere gene mutations are found in up to 25% and 3% of patients with familial disease and sporadic disease, respectively. The telomere gene TINF2 encodes an eponymous protein that is part of the shelterin complex, a complex involved in telomere protection and maintenance. A TINF2 gene mutation was recently reported in a family with pulmonary fibrosis. We identified a heterozygous Ser245Tyr mutation in the TINF2 gene of previously healthy female patient that presented with progressive cough due to pulmonary fibrosis as well as panhypogammaglobulinemia at age 52. Retrospective multidisciplinary evaluation classified her as a case of possible idiopathic pulmonary fibrosis. Telomere length-measurement indicated normal telomere length in the peripheral blood compartment. This is the first report of a TINF2 mutation in a patient with sporadic pulmonary fibrosis, which represents another association between TINF2 mutations and this disease. Furthermore, this case underlines the importance of telomere dysfunction and not telomere length alone in telomere syndromes and draws attention to hypogammaglobulinemia as a manifestation of telomere syndromes.

    The purpose of this study was to assess the prognosis of small cell lung cancer (SCLC) based on the underlying pulmonary disease. A total of 204 patients with SCLC were reviewed and categorized into three groups: normal, emphysema and fibrosis. The median overall survival duration (OS) in patients with normal lungs (n=57), with emphysema (n=105) and fibrosis (n=42) was 21.3, 16.4 and 10.8 months (p=0.063). In limited-stage disease (LD), the median OS in patients with fibrosis (7.4 months) was shorter than normal (52.7 months) or emphysema patients (26.4 months) (p=0.034). In extensive-stage disease (ED), the median OS in patients with fibrosis (12.7 months) was not significantly different from normal (11.4 months) or emphysema patients (13.5 months) (p=0.600). Patients with fibrosis had a poorer prognosis than normal or emphysema patients in LD-SCLC, but the coexistence of pulmonary fibrosis did not affect the prognostic outcomes in ED-SCLC.

    Background and purpose: Radiation induced lung fibrosis (RILF) is a major complication after lung irradiation and is very important for long term quality of life and could result in fatal respiratory insufficiency. However, there has been little information on dosimetric parameters for radiotherapy planning in the aspect of RILF. The features of RILF related with dosimetric parameters were evaluated. Methods and materials: Forty-eight patients with non-small cell lung carcinoma who underwent post-operative radiation therapy (PORT) without adjuvant chemotherapy were analyzed. The degree of lung fibrosis was estimated by fibrosis volume and the dosimetric parameters were calculated from the plan of 3-dimensional conformal radiotherapy. Results: The fibrosis volume and V-dose as dosimetric parameters showed significant correlation and the correlation coefficient ranged from 0.602 to 0.683 (P < 0.01). The degree of the correlation line was steeper as the dose increase and threshold dose was not found. Mean lung dose (MLD) showed strong correlation with fibrosis volume (correlation coefficient = 0.726, P < 0.01). Conclusions: The fibrosis volume is continuously increased with V-dose as the reference dose increases. MLD is useful as a single parameter for comparing rival plans in the aspect of RILF.

    Full Text Available Currently nonalcoholic fatty liver disease (NAFLD and nonalcoholic steatohepatitis (NASH are medical problems associated with the increasing prevalence of diabetes mellitus, obesity, hypertension and hypertriglyceridemia, usually designated as the metabolic syndrome associated with insulin resistance. One study demonstrated an increase in NAFLD prevalence of around 17-33% and in NASH prevalence of 5.7-16.5%. NAFLD comprises a range of mild to severe conditions, from simple steatosis to steatohepatitis, hepatic fibrosis and cirrhosis. The diagnosis of hepatic fibrosis is important for prognosis, stratification for treatment, and monitoring of treatment efficacy. Ultrasonography (USG is a simple method for detecting fatty infiltrates in the liver. USG has a sensitivity of 82-89% and a specificity of 93%, but cannot differentiate between hepatic steatosis and fibrosis. The gold standard for evaluation of hepatic fibrosis is liver biopsy, which however is a painful and invasive procedure. Currently determination of serum type IV collagen has been suggested as an alternative to liver biopsy among the non-invasive methods for evaluation of hepatic fibrosis, as its serum concentration is closely correlated with advanced hepatic fibrosis in NASH. Type IV collagen is one of the components of basement membrane and its serum concentration is indicative of degradation of the extracellular matrix.

  1. Cystic fibrosis: a mucosal immunodeficiency syndrome

    Cystic fibrosis transmembrane conductance regulator (CFTR) functions as a channel that regulates the transport of ions and the movement of water across the epithelial barrier. Mutations in CFTR, which form the basis for the clinical manifestations of cystic fibrosis, affect the epithelial innate immune function in the lung, resulting in exaggerated and ineffective airway inflammation that fails to eradicate pulmonary pathogens. Compounding the effects of excessive neutrophil recruitment, the mutant CFTR channel does not transport antioxidants to counteract neutrophil-associated oxidative stress. Whereas mutant CFTR expression in leukocytes outside of the lung does not markedly impair their function, the expected regulation of inflammation in the airways is clearly deficient in cystic fibrosis. The resulting bacterial infections, which are caused by organisms that have substantial genetic and metabolic flexibility, can resist multiple classes of antibiotics and evade phagocytic clearance. The development of animal models that approximate the human pulmonary phenotypes—airway inflammation and spontaneous infection—may provide the much-needed tools to establish how CFTR regulates mucosal immunity and to test directly the effect of pharmacologic potentiation and correction of mutant CFTR function on bacterial clearance.

    Pulmonary fibrosis is a vexing clinical problem with no proven therapeutic options. In the normal lung there is continuous collagen synthesis and collagen degradation, and these two processes are precisely balanced to maintain normal tissue architecture. With lung injury there is an increase in the rate of both collagen production and collagen degradation. The increase in collagen degradation is critical in preventing the formation of permanent scar tissue each time the lung is exposed to injury. In pulmonary fibrosis, collagen degradation does not keep pace with collagen production, resulting in extracellular accumulation of fibrillar collagen. Collagen degradation occurs through both extracellular and intracellular pathways. The extracellular pathway involves cleavage of collagen fibrils by proteolytic enzyme including the metalloproteinases. The less-well-described intracellular pathway involves binding and uptake of collagen fragments by fibroblasts and macrophages for lysosomal degradation. The relationship between these two pathways and their relevance to the development of fibrosis is complex. Fibrosis in the lung, liver, and skin has been associated with an impaired degradative environment. Much of the current scientific effort in fibrosis is focused on understanding the pathways that regulate increased collagen production. However, recent reports suggest an important role for collagen turnover and degradation in regulating the severity of tissue fibrosis. The objective of this review is to evaluate the roles of the extracellular and intracellular collagen degradation pathways in the development of fibrosis and to examine whether pulmonary fibrosis can be viewed as a disease of impaired matrix degradation rather than a disease of increased matrix production.

    Full Text Available The medical statements of the time show us a common opinion of the deplorable sanitary conditions of Madrid and of the most of its districts in the turn of the XIX century. This situation was so terrible that Madrid was named the «death city». In this project, using as the main sources the Healthy Demographic Statitiscs of the Town Council and of the Home Office, we aim to compare the information appeared in these statements and in the historiography studies with the one obtained by the exam of the variations in the mortality of Madrid districts between 1880 and 1931. In order to do that, this project is focused on the analyse of the changes on the general and infant mortalities and on the different Madrid districts rates of some diseases such as diarrhea and enteritis in under-2s, smallpox, diphtheria, pulmonary tuberculosis, flu and the other respiratory diseases. With all of this we try to know better its sanitary conditions in the period mentioned before.

    Full Text Available The frequency and duration of the warmest temperature episodes, a common phenomenon under the continental Mediterranean conditions of the Spanish Southern Meseta, has increased in the Madrid area since the 80´s, although their magnitude remains unchanged. The effect of the urban environment on those extreme events has exacerbated the heat load due to the persistence of the high temperatures along the night time hours. Nevertheless, the diversity of the urban morphology introduces a spatial variability on the strength of this nocturnal heat load, aggravating it in the densely urbanized areas and mitigating it in the vicinities of the green areas.

    La frecuencia y duración de los episodios cálidos extremos, un fenómeno habitual en el clima mediterráneo continental de la Meseta Meridional, ha aumentado en el área de Madrid desde los años noventa, aunque su magnitud permanece constante. En el interior de la aglomeración urbana, el efecto general de la ciudad sobre estos eventos climáticos extremos ha supuesto una exacerbación del calor, no tanto por un aumento de la temperatura máxima, como por una persistencia del calor en las horas nocturnas. No obstante, la diversidad de la morfología urbana introduce variaciones espaciales en la intensidad de este calor nocturno, agravando sus efectos en las áreas densamente urbanizadas y mitigándolos en las proximidades de las áreas verdes.

    Full Text Available Gammaherpesviruses (γHV are implicated in the pathogenesis of pulmonary fibrosis in humans and murine models of lung fibrosis, however there is little direct experimental evidence that such viruses induce lung fibrosis in the natural host. The equine γHV EHV 5 is associated with equine multinodular pulmonary fibrosis (EMPF, a progressive fibrosing lung disease in its natural host, the horse. Experimental reproduction of EMPF has not been attempted to date. We hypothesized that inoculation of EHV 5 isolated from cases of EMPF into the lungs of clinically normal horses would induce lung fibrosis similar to EMPF. Neutralizing antibody titers were measured in the horses before and after inoculation with EHV 5. PCR and virus isolation was used to detect EHV 5 in antemortem blood and BAL samples, and in tissues collected postmortem. Nodular pulmonary fibrosis and induction of myofibroblasts occurred in EHV 5 inoculated horses. Mean lung collagen in EHV 5 inoculated horses (80 µg/mg was significantly increased compared to control horses (26 µg/mg (p < 0.5, as was interstitial collagen (32.6% ± 1.2% vs 23% ± 1.4% (mean ± SEM; p < 0.001. Virus was difficult to detect in infected horses throughout the experiment, although EHV 5 antigen was detected in the lung by immunohistochemistry. We conclude that the γHV EHV 5 can induce lung fibrosis in the horse, and hypothesize that induction of fibrosis occurs while the virus is latent within the lung. This is the first example of a γHV inducing lung fibrosis in the natural host.

    To investigate hepatosplenic volumetry at MDCT for non-invasive prediction of hepatic fibrosis. Hepatosplenic volume analysis in 624 patients (mean age, 48.8 years; 311 M/313 F) at MDCT was performed using dedicated software and compared against pathological fibrosis stage (F0 = 374; F1 = 48; F2 = 40; F3 = 65; F4 = 97). The liver segmental volume ratio (LSVR) was defined by Couinaud segments I-III over segments IV-VIII. All pre-cirrhotic fibrosis stages (METAVIR F1-F3) were based on liver biopsy within 1 year of MDCT. LSVR and total splenic volumes increased with stage of fibrosis, with mean(±SD) values of: F0: 0.26 ± 0.06 and 215.1 ± 88.5 mm{sup 3}; F1: 0.25 ± 0.08 and 294.8 ± 153.4 mm{sup 3}; F2: 0.331 ± 0.12 and 291.6 ± 197.1 mm{sup 3}; F3: 0.39 ± 0.15 and 509.6 ± 402.6 mm{sup 3}; F4: 0.56 ± 0.30 and 790.7 ± 450.3 mm{sup 3}, respectively. Total hepatic volumes showed poor discrimination (F0: 1674 ± 320 mm{sup 3}; F4: 1631 ± 691 mm{sup 3}). For discriminating advanced fibrosis (≥F3), the ROC AUC values for LSVR, total liver volume, splenic volume and LSVR/spleen combined were 0.863, 0.506, 0.890 and 0.947, respectively. Relative changes in segmental liver volumes and total splenic volume allow for non-invasive staging of hepatic fibrosis, whereas total liver volume is a poor predictor. Unlike liver biopsy or elastography, these CT volumetric biomarkers can be obtained retrospectively on routine scans obtained for other indications. (orig.)

Recent findings Epidemiological and histochemical studies demonstrated....... Increasingly poor renal function, aberrations in calcium-phosphate metabolism and erythropoietin treatment seem to increase the risk of the disease and its severity. Up to 25-30% of patients with renal failure exposed to gadolinium-based contrast agents may develop nephrogenic systemic disease. The figure...... that gadolinium-containing contrast agents used for magnetic resonance imaging have an essential causative role in most, if not all, cases of nephrogenic systemic fibrosis. One particular agent, gadodiamide, caused the majority of cases, but gadopentetate dimeglumine has also been implicated in several cases...

    Liver stiffness measurement (LSM) has recently become available for assessment of liver fibrosis. We aimed to develop a prediction model for liver fibrosis using clinical variables, including LSM. We performed a prospective study to compare liver fibrosis grade with fibrosis score. LSM was measured using magnetic resonance elastography in 184 patients that underwent liver resection, and liver fibrosis grade was diagnosed histologically after surgery. Using the prediction model established in the training group, we validated the classification accuracy in the independent test group. First, we determined a cut-off value for stratifying fibrosis grade using LSM in 122 patients in the training group, and correctly diagnosed fibrosis grades of 62 patients in the test group with a total accuracy of 69.3%. Next, on least absolute shrinkage and selection operator analysis in the training group, LSM (r = 0.687, P prediction model. This prediction model applied to the test group correctly diagnosed 32 of 36 (88.8%) Grade I (F0 and F1) patients, 13 of 18 (72.2%) Grade II (F2 and F3) patients, and 7 of 8 (87.5%) Grade III (F4) patients in the test group, with a total accuracy of 83.8%. The prediction model based on LSM, ICGR15, and platelet count can accurately and reproducibly predict liver fibrosis grade.

    Background: To evaluate alternative treatment regimen e.g. neutron therapy determination of treatment efficacy as well as side effects is important. Sensitivity of computed tomography (CT) in detecting changes of connective tissue after neutron therapy was examined. Patients and Methods: In the course of their follow-up period (median 45 months) 12 patients with malignant salivary gland tumors who had postoperatively received neutron (1/12) or photon/neutron therapy (11/12) were examined by means of CT densimetry on 3 representative scans in the area of radiotherapy. In 3 ROI (regions of interest) in subcutaneous fatty tissue the density at the irradiated and the non-irradiated side was determined according to Hounsfield units (HU) and the average density was calculated. The average density of both sides was compared and correlated with the clinical grade of fibrosis according to LENT SOMA. Results: All CT measurements (216 ROI, 18 ROI per patient) showed higher density levels on the irradiated side than on the non-irradiated side. The average density on the irradiated side was -57.7±4.7 HU and on the non-irradiated side -69.4±5.8 HU (p=0.002). In 3/12 patients a clinical fibrosis was not seen; however, the relative density measured on the irradiated and non-irradiated side deviated by up to 8%. This could have been caused by minimal changes not being noticed by either patient and examiner. In patients with determined fibrosis Grade 1 (8/12) the relative density deviation was 4 to 39%. In 1/12 patients with determined fibrosis Grade 2 the relative density deviation was 50%. Fibrosis Grade 3 and 4 did not occur. Conclusions: Fibrosis is correlated with an increasing value of HU of the tissue density in CT. With the described method it is possible to graduate radiation induced subcutaneous fibrosis in correlation to the clinical fibrosis grade according to LENT SOMA. In the patients we examined subcutaneous fibroses after photon/neutron therapy were moderate

    2015-01-01

    Fibrosis is a characteristic pathological feature of an array of chronic diseases, where development of fibrosis in tissue can lead to marked alterations in the architecture of the affected organs. As a result of this process of sustained attrition to organs, many diseases that involve fibrosis are often progressive conditions and have a poor long-term prognosis. Inflammation is often a prelude to fibrosis, with innate and adaptive immunity involved in both the initiation and regulation of the fibrotic process. In this review, we will focus on the emerging roles of the newly described innate lymphoid cells (ILCs) in the generation of fibrotic disease with an examination of the potential interplay between ILC and macrophages and the adaptive immune system.

  20. Genetics and Early Detection in Idiopathic Pulmonary Fibrosis

    Putman, Rachel K.; Rosas, Ivan O.

    2014-01-01

    Genetic studies hold promise in helping to identify patients with early idiopathic pulmonary fibrosis (IPF). Recent studies using chest computed tomograms (CTs) in smokers and in the general population have demonstrated that imaging abnormalities suggestive of an early stage of pulmonary fibrosis are not uncommon and are associated with respiratory symptoms, physical examination abnormalities, and physiologic decrements expected, but less severe than those noted in patients with IPF. Similarly, recent genetic studies have demonstrated strong and replicable associations between a common promoter polymorphism in the mucin 5B gene (MUC5B) and both IPF and the presence of abnormal imaging findings in the general population. Despite these findings, it is important to note that the definition of early-stage IPF remains unclear, limited data exist to definitively connect abnormal imaging findings to IPF, and genetic studies assessing early-stage pulmonary fibrosis remain in their infancy. In this perspective we provide updated information on interstitial lung abnormalities and their connection to IPF. We summarize information on the genetics of pulmonary fibrosis by focusing on the recent genetic findings of MUC5B. Finally, we discuss the implications of these findings and suggest a roadmap for the use of genetics in the detection of early IPF. PMID:24547893
